only when used with numbers. Abbreviations used as<br />

legends in tables and/or figures should be duly defined<br />

below the respective item.<br />

NUMBERS AND UNITS<br />

Measurements of length, height, weight and<br />

volume must be reported in metric units (meter,<br />

kilogram, liter etc.) or their decimal multiples.<br />

Temperature should be given in degrees Celsius.<br />

Blood pressure in mm Hg, and hematological and<br />

Obesity is a major public health problem in the<br />

developed and developing regions of the world.<br />

Using a body mass index (weight in kg divided by<br />

height in meter squared) of 30 kg/m 2 or greater as the<br />

cut-off, recent estimates indicate that 36% of adults<br />

in the United States are obese [1] . The prevalence of<br />

severe or morbid obesity defined as BMI greater<br />

than 40 kg/m 2 is rising twice as fast as that of obesity<br />

and is currently close to 6% of US adult population.<br />

Obesity is associated with increased risk of morbidity<br />

and mortality from cardiovascular disease, diabetes,<br />

respiratory diseases, musculoskeletal disorders and<br />

neoplastic diseases, among others [2] . Management of<br />

obesity continues to be challenging, and traditional<br />

options based on dietary and lifestyle modifications<br />

seldom result in sustained weight loss. Compared<br />

with the proliferation of agents for diabetes therapy,<br />

the pace of drug development for obesity has been<br />

markedly slower. Moreover, the available agents are<br />

of limited efficacy [3] , especially with regard to making<br />

an impact on morbid obesity.<br />

Superficial interventions such as liposuction<br />

and removal of subcutaneous abdominal adipose<br />

tissue do not alter cardio-metabolic risks [4] . By<br />

contrast, gastric bypass surgery offers long-term<br />

weight loss associated with significant reduction<br />

of comorbidities associated with morbid obesity [5] .<br />

Complete resolution of diabetes occurs in 80% of<br />

patients while an additional number of patients see<br />

significant improvement in diabetes [6,7] . This happens<br />

through both weight-dependent as well as weightindependent<br />

mechanisms including alteration in<br />

bile flow, reduction of gastric size, anatomical gut<br />

rearrangement, vagal manipulation, and alterations<br />

in enteric hormones [6] . In addition, hyperlipidemia,<br />

hypertension and obstructive sleep apnea improve in<br />

70%, 62% and 84% of patients respectively [8] . A large<br />

cohort study showed a 40% reduction in mortality<br />

from all causes associated with bariatric surgery [9] .<br />

Unfortunately, the cosmetic and cardio-metabolic<br />

benefits of bariatric surgery are achieved at a price of<br />

significant post-operative morbidity and sometimes<br />

mortality. However, the outcomes of bariatric surgery<br />

are generally improving over time with the use of more<br />

advanced surgical procedures, more careful selection<br />

of surgical candidates, and the use of specialized<br />

surgery centers. The overall 30-day mortality<br />

for bariatric surgical procedures is less than one<br />

percent [8] . Some of the more common complications of<br />

bariatric surgery include ventral and internal hernias,<br />

metabolic and nutritional derangements, marginal<br />

ulcers, short bowel syndrome, dumping syndrome<br />

and cholelithiasis [10] .<br />

An uncommon but potentially serious adverse effect<br />

of bariatric surgery is recurrent severe hypoglycemia.<br />

As is well-known, hypoglycemia is rare among nondiabetic<br />

persons [11] . Although mild asymptomatic<br />

hypoglycemia can be as seen in up to 50% of postbypass<br />

patients, severe hypoglycemia accompanied by<br />

neuroglycopenic symptoms occurs in less than 1% of<br />

bariatric surgery patients [6,12] . The presentation of mild<br />

episodes of hypoglycemia is similar to that of the late<br />

phase of dumping syndrome and usually responds to<br />

dietary modifications [5] . Although much less frequent,<br />

episodes of severe hypoglycemia can have dramatic<br />

clinical presentations, including confusion, seizure<br />

and coma. Impaired cognitive function, altered<br />

neuromuscular reflexes, and diminished capacity for<br />

judgment resulting from neuroglycopenia can lead<br />

to automobile accidents and machinery injuries. In<br />

275 Bariatric Surgery and Hypoglycemia<br />

<strong>December</strong> <strong>2012</strong><br />

gastric banding (n = 2,917) for obesity, the relative<br />

risk of severe hypoglycemia was five-fold higher in<br />

the gastric bypass patients compared with controls [12] .<br />

However, it is noteworthy (and reassuring) that the<br />

absolute rate of post-bariatric hypoglycemia was<br />

low (< 1%). Furthermore, the Roux-en-Y gastric<br />

bypass procedure was more frequently associated<br />

with hypoglycemia than other forms of bariatric<br />

surgery, including vertical banding gastroplasty and<br />

gastric banding [12] . The median time from surgery to<br />

hypoglycemic symptoms in the Swedish survey was<br />

2.7 years, consistent with the post-operative latency<br />

of 1 - 5 years reported in other series [5,13-15] . Of note,<br />

the frequency of accidental deaths was higher in postbariatric<br />

surgery patients than in reference cohorts,<br />

which may indicate undiagnosed hypoglycemia and<br />

possible underestimation of the number of patients<br />

with hypoglycemia [12] .<br />

Classically, hypoglycemia in post-gastric<br />

bypass patients occurs postprandially or during<br />

the postabsorptive period (as opposed to during<br />

fasting). Post-gastric bypass hypoglycemia usually is<br />

associated with the concurrence of low serum glucose<br />

levels (typically < 60 mg/dl) and inappropriately<br />

elevated or measurable levels of insulin and C-<br />

peptide. The mechanisms behind post-gastric<br />

bypass hyperinsulinemic hypoglycemia are not<br />

well-understood. In 2005, Service et al reported a<br />

series of six patients with symptomatic postprandial<br />

hyperinsulinemic hypoglycemia that developed on<br />

average 30 months after gastric bypass surgery [16] .<br />

Insulinoma was ruled out using imaging studies and<br />

selective arterial calcium stimulation test [16] . These<br />

patients then underwent either extensive or spleenpreserving<br />

distal pancreatectomy, and islet specimens<br />

were obtained for histological study. The pancreatic<br />

islet sections obtained from the patients reported by<br />

Service et al showed evidence of nesidioblastosis<br />

(hypertrophic beta cells, with enlarged or normalappearing<br />

islets; small scattered clusters of endocrine<br />

cells; and ductuloinsular complexes) [16] . The authors<br />

thus concluded that insulin hypersecretion from<br />

nesidioblasts was responsible for post-gastric bypass<br />

hypoglycemia in their patients [16] . However, reexamination<br />

of the pancreatic histology by Meier<br />

et al raised doubts about the presence of true<br />

nesidioblasts [17] . Instead, evidence of increased beta<br />

cell nuclear diameter was observed in post-gastric<br />

bypass patients compared with controls [17] . Thus, the<br />

hypoglycemia in such patients could have arisen from<br />

a combination of exaggerated “dumping” syndrome<br />

and increased insulin secretion per beta cell.<br />

Another mechanism proposed for the insulin<br />

hypersecretion and possible islet cell proliferation was<br />

enhanced glucagon-like peptide 1 (GLP-1) secretion<br />

from L cells in distal ileum, resulting from the rapid<br />

transit of nutrients following gastric bypass surgery [16] .<br />

Indeed, studies identifiedexaggeratedGLP-1response<br />

and attendant insulinotropic and glucagonostatic<br />

effects as mechanisms for post-gastric bypass<br />

hypoglycemia [18,19] . Since the mechanisms underlying<br />

post-bariatric hypoglycemia are not fully understood,<br />

a standard approach to management has not yet been<br />

developed. Mild hypoglycemia may be evaluated<br />

and treated in an outpatient setting. However severe<br />

hypoglycemia likely requires hospitalization and<br />

evaluation to rule out etiologies such as insulinoma.<br />

Without randomized controlled studies, the<br />

therapeutic approach to severe post-bariatric surgery<br />

hypoglycemia has been empirical. Management<br />

usually begins with dietary modification, including<br />

frequent small meals with low carbohydrate content.<br />

Pharmacological approaches that have had variable<br />

success include diazoxide, acarbose, octreotide, and<br />

calcium channel blockers [6, 13, 20] . For patients with<br />

refractory hypoglycemia, surgical intervention may<br />

be warranted, either to reverse the gastric restriction<br />

procedure or reduce the mass of insulin-secreting<br />

pancreatic tissue [5- 7, 14- 16] .<br />

In summary, severe hyperinsulinemic hypoglycemia<br />

is a rare but serious sequel of gastric bypass surgery.<br />

It usually presents a few years after the surgery and is<br />

accompanied by neuroglycopenic symptoms including<br />

confusion, seizure, syncope or coma. Future studies<br />

should be directed at unraveling the mechanisms,<br />

identifying risk factors, and developing optimal<br />

surveillance and management strategies for post-gastric<br />

bypass hypoglycemia. While awaiting the results of<br />

definitive studies on the subject, clinicians should be<br />

cognizant of the risk of hypoglycemia, educate gastric<br />

bypass patients on the warning symptoms of impending<br />

hypoglycemia and appropriate corrective measures.<br />

ABSTRACT<br />

Asthma is one of the most common medical conditions<br />

to complicate pregnancy and represents a significant<br />

public health issue. Increased maternal complications<br />

and adverse fetal outcomes are associated with asthma<br />

during pregnancy. Since asthma can adversely affect the<br />

outcome of pregnancy, it is important for us to understand<br />

the mechanisms underlying asthma during pregnancy.<br />

In general, asthma is characterized by an up-regulated<br />

systemic production of T-helper 2 (Th2) cytokines.<br />

Pregnancy also brings about changes in maternal immune<br />

status making it polarized towards the Th2 phenotype.<br />

Based on these considerations, we hypothesize that<br />

pregnancy-induced immune alterations may modify<br />

allergic mechanisms of asthma and that systemic Th2<br />

cytokine and chemokine polarization does occur among<br />

asthmatics to a greater extent during pregnancy. We<br />

suggest that this is associated with exacerbation of asthma<br />

during pregnancy. The pathophysiology of asthma during<br />

pregnancy and the interrelationship between these two<br />

conditions are reviewed here.<br />

KEY WORDS: allergy, cytokines, Th1, Th2<br />

INTRODUCTION<br />

Asthma is one of the most common medical<br />

conditions in the world. It is also the most common<br />

condition affecting the lungs during pregnancy.<br />

About 7-12% of pregnant women may be affected by<br />

asthma, making asthma one of the most important<br />

medical conditions complicating pregnancy [1-3] .<br />

Asthma influences the outcome of pregnancy; it is<br />

considered to be a risk factor for several maternal and<br />

fetal complications, such as asthma exacerbations,<br />

hospitalizations because of asthma attacks, preeclampsia,<br />

preterm delivery, cesarean delivery,<br />

gestational hypertension, low birth weight and a higher<br />

risk of perinatal mortality [4,5] . Conversely, pregnancy<br />

also influences the severity of asthma; during<br />

pregnancy, approximately one third of asthmatic<br />

women experience exacerbation of their symptoms [6,7] .<br />

Women who have more severe asthma before<br />

pregnancy appear more likely to experience worsening<br />

asthma during pregnancy [8,9] ; prospective studies have<br />

shown that asthma is more likely to deteriorate during<br />

pregnancy in women with severe asthma than in those<br />

with mild asthma [1, 10] . Maintenance of optimal asthma<br />

control during pregnancy reduces maternal and fetal<br />

risk for complications [1] .<br />

Two questions about the interaction of asthma and<br />

pregnancy are raised by clinicians and patients alike:<br />

(i) How does pregnancy affect asthma? (ii) How does<br />

asthma affect the outcome of pregnancy? Asthma is<br />

an immunologic disease, and pregnancy brings about<br />

changes in the immune system. Thus, it is of interest to<br />

view asthma during pregnancy from an immunologic<br />

perspective.<br />

While the underlying immunologic mechanisms<br />

of the interactions between asthma and pregnancy are<br />

not fully understood, this review summarizes current<br />

knowledge about the immunology of asthma and<br />

the immunology of pregnancy, and suggests possible<br />

mechanisms for immunological interactions between<br />

asthma and pregnancy.<br />

ASTHMA<br />

The immune system surely does a splendid job<br />

of protecting us from infectious diseases (much of<br />

the time!). However, inappropriate responses of this<br />

system can lead to disease. Allergies and asthma are<br />

common among the outcome of immune dysfunction.<br />

Discomfort or even distress from common allergies<br />

may seem minor compared to life-threatening<br />

problems such as cancer or cardiovascular diseases,<br />

but asthma is a serious problem that can cause severe<br />

difficulties in breathing. The real significance of<br />

asthma is demonstrated by the number of visits to<br />

the doctor and to the emergency room and days spent<br />

in the hospital [11] ; in fact, the number of visits to the<br />

doctor for hypertension or for pregnancy or general<br />

examination is each fewer than the number of visits<br />

for asthma. Indeed, the single most common reason for<br />

a visit to the emergency room in the Western world is<br />

an asthma attack.<br />

Asthma is a worldwide disease and a common one.<br />

With about 5% of the population in Western countries<br />

affected, there is no reason to assume that the incidence<br />

of asthma is lower in Kuwait and the Arabian Gulf.<br />

In fact, despite low allergen exposure, the pattern of<br />

childhood asthma in Kuwait follows that described<br />

in Western communities [12,13] . In Kuwait, the average<br />

annual admission rate for asthma per 100,000 people<br />

was 217 in the 1992-1994 period and the mean annual<br />

death rate per 100,000 people was about 1.6. The<br />

number of Kuwaiti patients being admitted for asthma<br />

has increased [13] . A survey made by the Asthma Insights<br />

and Reality in the Gulf and Near East (AIRGNE) of<br />

Jordan, Kuwait, Lebanon, Oman and the UAE in 2009<br />

showed that the comparative population prevalence of<br />

diagnosed current asthma was high, ranging from 23%<br />

in Kuwait to 32% in Lebanon [14] .<br />

IMMUNOPATHOGENESIS OF ASTHMA<br />

Asthma, also known as reversible obstructive airway<br />

disease, is characterized by hyperresponsiveness<br />

of the tracheobronchial tree to respiratory irritants<br />

and bronchoconstrictor chemicals producing attacks<br />

of wheezing, dyspnea, chest tightness and cough.<br />

This chronic respiratory disease is characterized by<br />

episodes of inflammation and narrowing of small<br />

airways in response to triggers of asthma. Asthma can<br />

be triggered by a variety of factors including allergens,<br />

infections, exercise, abrupt changes in the weather and<br />

exposure to airway irritants such as tobacco smoke.<br />

Asthma attacks can vary from mild to life-threatening.<br />

Asthma can be due to either an allergic response<br />

or a non-allergic response. Asthma due to an allergic<br />

response is also known as allergic asthma, extrinsic<br />

asthma, atopic asthma or immunologic asthma. 50% of<br />

asthma cases are “allergic-asthma” [4] . Allergic asthma<br />

is triggered by air-borne or blood-borne allergens<br />

such as pollen, dust, fumes, insect products or viral<br />

products. Non-allergic asthma, also known as intrinsic<br />

or idiopathic asthma, is induced by cold or exercise,<br />

apparently independently of allergens. However,<br />

regardless of the presence or absence of allergy, all<br />

asthmatic patients have the cardinal features of airway<br />

hyperreactivity, airway obstruction and eosinophilia.<br />

Allergic asthma in genetically susceptible<br />

individuals is a result of dysregulated immune<br />

responses to common environmental antigens. The<br />

pathogenesis of asthma involves cytokine production<br />

from T helper 2 (Th2) lymphocytes that in turn<br />

orchestrate the allergic inflammatory response. Upon<br />

recognition of an allergen, Th2 cells produce cytokines<br />

that induce IgE synthesis, activate eosinophils and mast<br />

cells, and up-regulate expression of adhesion molecules<br />

on endothelial and epithelial cells. Eosinophils are<br />

a key component of chronic allergic disease and<br />

contribute to many of the pathological processes of<br />

asthma producing molecules that stimulate vasomotor<br />

activity, bronchoconstriction and mucus secretion. They<br />

also produce a variety of pro-inflammatory cytokines<br />

such as tumor necrosis factor (TNF) α, interleukin<br />

(IL)-1 and IL-6. Anti-allergen IgE antibodies first bind<br />

to mast cells; subsequent exposure to the allergen<br />

triggers an IgE-mediated release of mediators that<br />

may cause an asthmatic attack. IgE-sensitized mast<br />

cells and basophils secrete several mediators such as<br />

histamine, leukotrienes and prostaglandins which<br />

lead to bronchoconstriction, vasodilation and buildup<br />

of mucus. Subsequently, other mediators including<br />

eosinophil-chemotactic factor, platelet-activating factor<br />

and the cytokines IL-4, IL-5 and TNFα are released;<br />

these mediators increase endothelial cell adhesion<br />

and recruit inflammatory cells such as eosinophils and<br />

neutrophils into the bronchial tissue.<br />

As Th2 reactivity is critical to the development<br />

of asthma, it is pertinent to elaborate on Th1/Th2<br />

dichotomy at this point.<br />

Th1 AND Th2 REACTIVITY<br />

One of the most significant advances in our<br />

understanding of immune responses has been the<br />

delineation of the Th1/Th2 paradigm, which provides<br />

a framework for understanding how the immune<br />

system directs responses to different types of pathogens<br />

and antigens. The two major subsets of CD4 + T helper<br />

cells, Th1 and Th2, have different patterns of cytokine<br />

production and different roles in immune responses.<br />

Each subset induces functions that are effective at<br />

handling certain types of pathogens, but can be<br />

ineffective, or may even have pathological effects if<br />

made in response to other types of pathogens [15, 16] .<br />

Th1 cells secrete IFNγ, TNFβ, IL-2 and TNFα, the so<br />

called Th1-type cytokines. Th1-type cytokines activate<br />

cell-mediated reactions important in resistance to<br />

infection by intracellular pathogens, and in cytotoxic<br />

and delayed-type hypersensitivity (DTH) reactions.<br />

Th2 cells, on the other hand, secrete IL-4, IL-5, IL-6, IL-<br />

10 and IL-13; these Th2-type cytokines promote robust<br />

antibody production and are therefore commonly<br />

found in association with strong antibody responses<br />

that are important in combating infections with<br />

extracellular <strong>org</strong>anisms. Which type of reactivity, Th1<br />

or Th2 is activated first may influence the subsequent

outcome; if a particular T cell subset is activated first<br />

or preferentially in a response, it can suppress the<br />

development of the other subset. The overall effect is<br />

that responses are often dominated by either humoral<br />

(Th2) or cell-mediated (Th1) immunity [15,16] .<br />

ASTHMA IS A Th2-MEDIATED REACTIVITY<br />

The generation of Th2 cells and the development<br />

of Th2-type reactivity are crucially dependent on the<br />

cytokine IL-4 [15,16] . Th2 development is greatly favored<br />

once a threshold level of IL-4 is reached. Th2 cells<br />

provide help to B cells and promote the production<br />

of relatively large amounts of IgE, IgM and noncomplement<br />

fixing IgG. In addition, Th2 cells cause<br />

mast cell growth via the production of IL-4, IL-10 and<br />

IL-13 and stimulate eosinophil activation via IL-5 [17] . It<br />

should be emphasized that Th2 cells support allergic<br />

reactions via the production of the quintessential Th2<br />

cytokines, IL-4 and IL-5 [17] and also IL-13 [18] . The coculture<br />

of CD4 + T cells with peripheral blood monocytes<br />

from atopic asthmatic subjects results in enhanced<br />

production of IL-4 and IL-5 [19] . The Th2 cytokine IL-<br />

4 thus plays prominent and indispensable roles in at<br />

least two stages of an allergic response – first, during<br />

the development of Th2 cells from its precursor (Fig.<br />

1) and second, during the activation of mast cells by<br />

Th2 cells (Fig. 2). The Th2 cytokine IL-13 induces IgE<br />

production by B cells.<br />

IL-4 [20] and IL-13 [21] both provide an essential first<br />

signal for an IgG → IgE switch in B cells. The Th2<br />

cytokines IL-5 and IL-6 enhance IgE production.<br />

Interestingly enough, the opposing or antagonistic<br />

natures of Th1 and Th2 cells ensure that Th1 cells<br />

do not support IgE synthesis [22] . Furthermore, the<br />

Th1 cytokines IFNγ and TNFα and the inflammatory<br />

cytokines IL-8 and IL-23 are inhibitory to IgE<br />

production. Thus there is clear evidence linking<br />

activation of allergen-specific Th2 cells to pathology in<br />

atopic allergic disease [23] and clearly allergic asthma is<br />

a Th2 phenomenon [24, 25] , while Th1 reactivity actually<br />

inhibits the development of allergy by inhibiting Th2<br />

development. As shown in Fig. 1, the Th2 cytokines IL-<br />

4, IL-5 and IL-10 are involved in the initial sequence of<br />

steps activating the production of IgE antibodies and<br />

subsequently in the activation of mast cells to produce<br />

other mediators which actually bring about allergic<br />

manifestations. Just as IL-4 is intimately involved in<br />

the development of Th2 reactivity, it also plays critical<br />

roles in the activation of mast cells as shown in Fig. 2.<br />

Levels of the Th2 cytokine IL-13 are increased in<br />

the airway mucosa of patients with asthma [26] and<br />

challenge with allergen results in increased levels of<br />

IL-13 in addition to IL-4. The administration of IL-13<br />

to mice increases airway eosinophilia and bronchial<br />

hyperresponsiveness. IL-13 induces inflammation<br />

by stimulating the expression of chemokines (i.e.,<br />

cytokines that are chemotactic for immune cells) such<br />

as eotaxin from cells in the airways and also induces<br />

airway hyperresponsiveness and hypersecretion of<br />

mucous in the airway epithelium [27] . Atopic asthma<br />

is characterized by increased production of Th2<br />

cytokines [1, 28] ; some studies have also reported upregulation<br />

of systemic Th2 cytokine production<br />

associated with increased symptoms of allergy [1] .<br />

Allergy is thus a Th2 phenomenon, and Th2 cytokines<br />

are intimately involved in the stimulation of allergy<br />

(Fig. 1 and 2) while Th1 cytokines are actually<br />

antagonistic to allergy.<br />

In addition to Th2-type cytokines, other cytokines<br />

such as IL-8 are also implicated in the development<br />

of asthma and in the chronic inflammatory<br />

processes of asthma by contributing to the release of<br />

inflammatory mediators such as histamine, airway<br />

remodeling, bronchoconstriction and bronchial<br />

hyperresponsiveness [29] . Chemokines are important in<br />

asthma, as they are involved in attracting leukocytes<br />

from the circulation into the airways [30, 31] . Particularly<br />

important among these are the chemokines RANTES,

chemoattractant [32] and induces respiratory burst in<br />

elevated in individuals with asthma and eosinophilia,<br />

and many studies have evaluated its role in local<br />

tissues [35] .<br />

DOES ASTHMA GET BETTER OR WORSE<br />

DURING PREGNANCY?<br />

Asthma is the most common chronic condition<br />

to complicate pregnancy. During pregnancy,<br />

approximately one third of asthmatic women<br />

experience an exacerbation [6,7] . Women who have more<br />

severe asthma before pregnancy appear more likely<br />

to experience worsening asthma symptoms during<br />

pregnancy [8,9] ; prospective studies have shown that<br />

asthma is more likely to deteriorate during pregnancy<br />

in women with severe asthma (52 - 65%) than in those<br />

with mild asthma (8 - 13%) [10,36] .<br />

What happens to asthmatic women when they<br />

get pregnant? Do the symptoms get better or do they<br />

get worse? The consensus is that one-third of females<br />

experience a worsening of asthma during pregnancy,<br />

one-third improve and one-third remain unchanged [9,37-<br />

39]<br />

(Fig. 3). It is unclear whether this is due to changes<br />

in asthma severity, changes in asthma control or<br />

exacerbations during pregnancy. A variety of methods<br />

have been used to obtain this data. Most studies have<br />

used subjective questionnaires to ascertain the global<br />

change in asthma experienced during pregnancy, while<br />

a few studies have obtained data from daily recordings<br />

of symptom or changes in treatment requirements.<br />

However, even though only a few studies have<br />

examined objective measures such as lung function by<br />

peak spirometry or airway hyperresponsiveness, the<br />

general trend seems to support the notion that asthma<br />

symptoms worsen in about 24 - 43% of asthmatic<br />

women during pregnancy, improve in about 14 - 42%<br />

of women and are unchanged in 24 - 43% of women.<br />

For example, Williams examined hospital records<br />

and reported that asthma gets worse in 24% of<br />

pregnant women, remains the same in 34% and<br />

symptoms improve in 42% of pregnant women [40] .<br />

Similarly, Schatz et al evaluated asthma in 336 pregnant<br />

women based on the daily symptoms diaries as well<br />

as by subjective classification of overall changes and<br />

reported that asthma became worse in 35% of women,<br />

unchanged in 33% and improved in 28% [38] . The same<br />

evaluation based on the same criteria was reported more<br />

recently and the percentages were 36%, 26% and 34%<br />

respectively [41] . Based on questionnaires on symptoms<br />

and self-report of overall changes in breathing, many<br />

others reported that asthma in pregnant women got<br />

worse in 34 - 41%, remained the same in 24 - 31% and<br />

improved in 28 - 35% [3,42] .<br />

In subjects whose asthma worsened, a significant<br />

increase has been reported in the number of days of<br />

wheezing and interference with sleep and activity<br />

between 25 - 32 weeks gestation [38] . In asthmatic<br />

subjects who felt their asthma improved overall,<br />

there was a decrease in wheezing with little change<br />

in interference with sleep or activity between 25 - 32<br />

weeks gestation. Most subjects who felt their asthma<br />

worsened during pregnancy actually improved postpartum,<br />

with significantly fewer days of wheezing<br />

at 5 - 12 weeks post-partum compared with 29 - 32<br />

weeks of gestation. Conversely, most subjects who<br />

felt their asthma improved during pregnancy later<br />

worsened after delivery, with significantly more days<br />

of interference of activity in this period compared with<br />

29 - 36 weeks of gestation. In general, increased asthma<br />

severity during pregnancy is associated with greater<br />

morbidity in the mother and newborn [38] .<br />

In summary then, the paradigm has remained for<br />

decades that during pregnancy, asthma will worsen in<br />

one-third of women, remain the same in one-third and<br />

improve in one-third.<br />

MECHANISMS OF PREGNANCY-INDUCED<br />

CHANGES IN ASTHMA<br />

The mechanisms that contribute to changes in<br />

asthma during pregnancy are not well understood,<br />

although increases in maternal circulating hormones,<br />

altered 2-adrenoreceptor responsiveness or fetal sex<br />

have been suggested to be involved (Fig. 4). One<br />

could postulate that elevations in both estrogen<br />

and progesterone that occur particularly during<br />

the first trimester may contribute to the severity of<br />

asthma during pregnancy. Evidence for this can be<br />

found from the multiple studies that have reported<br />

associations between higher levels of hormones<br />

and asthma symptoms. For example, more frequent

Asthma during Pregnancy: An Immunologic Perspective<br />

<strong>December</strong> <strong>2012</strong><br />

Fig. 4: Possible effects of asthma on the outcome of pregnancy<br />

asthma symptoms have been reported in association<br />

with menstruation [43] and in association with hormone<br />

replacement therapy [<strong>44</strong>,45] . Increased progesterone<br />

levels, in both animals [46] and humans [<strong>44</strong>,45] , have<br />

been associated with worsening asthma symptoms<br />

in several, but not all studies [47] . Both estrogen and<br />

progesterone have been shown to up-regulate Th2<br />

cytokine production both in vitro [48,49] and in vivo [50] .<br />

The pregnancy-associated rise in serum-free cortisol<br />

may contribute to improvements in asthma during<br />

pregnancy [51] , since cortisol has anti-inflammatory<br />

properties. In addition, estradiol and progesterone<br />

concentrations increase significantly during<br />

pregnancy [51] . Progesterone is known to contribute to<br />

increased ventilation during normal pregnancy [52] and<br />

is also a potent smooth muscle relaxant [53] and may,<br />

therefore, be expected to contribute to improved asthma<br />

during pregnancy. On the other hand, progesterone<br />

has been shown to induce Th2-type reactivity [54-56] and<br />

thus pregnancy-associated increase in progesterone<br />

levels may be postulated to result in an increased Th2-<br />

bias and thus increased severity of asthma.<br />

Changes in β2-adrenoreceptor responsiveness<br />

and airway inflammation as a result of circulating<br />

progesterone may also contribute to worsening asthma<br />

during pregnancy [52] . Alterations in asthma associated<br />

with changes in sex steroid production during the<br />

menstrual cycle have previously been observed [57] ,<br />

with up to 40% of females experiencing an exacerbation<br />

around the time of menstruation when progesterone<br />

and estradiol levels are low [58] .<br />

The season of pregnancy or delivery was not<br />

found to affect asthma progression [38] , suggesting<br />

that allergen exposure may not play a role in asthma<br />

alterations with pregnancy. Kircher et al [41] suggest<br />

that factors, such as IgE, which affect both the upper<br />

and lower airways, may be important in changes that<br />

occur in asthma during pregnancy. Early studies by<br />

Gluck and Gluck [37] also showed a correlation between<br />

increased serum IgE and deteriorating asthma during<br />

pregnancy.<br />

An observation that is worth mentioning here in<br />

terms of mechanisms and clinical relevance, is pertinent<br />

to the course of asthma during pregnancy. More severe<br />

asthma tends to worsen during pregnancy, whereas<br />

less severe asthma tends to remain unchanged or<br />

tends to improve [38] . The relationship between asthma<br />

severity classification and subsequent changes in<br />

asthma during pregnancy was assessed in a study<br />

on 1,700 pregnant asthmatics [7] . Exacerbations of<br />

asthma occurred in over half of all severe asthmatics,<br />

while only 12% of patients with mild asthma had<br />

exacerbations during pregnancy.<br />

It is tempting to suggest that perhaps maternal<br />

immune factors, such as the prevailing Th2 versus<br />

Th1 cytokine profile, may be one of the determinants<br />

of whether an asthmatic woman will get better or<br />

worse when she gets pregnant. Is this possibly due to<br />

an already heavily Th2-biased immune system tilting<br />

towards a stronger Th2 bias during pregnancy?<br />

IMPACT OF ASTHMA ON PREGNANCY<br />

In addition to the observed effects of pregnancy<br />

on asthma, it is also well-recognized that women<br />

with asthma are at increased risk of poor pregnancy<br />

outcomes [59] . Cases of severe life-threatening asthma<br />

requiring first trimester termination of pregnancy have<br />

been reported and an improvement in maternal asthma<br />

within 24 hours of termination has been observed [60] .<br />

Epidemiological studies have demonstrated that<br />

asthmatic females are at increased risk of many poor<br />

outcomes of pregnancy. Uncontrolled asthma in<br />

pregnant women can result in perinatal complications<br />

and exacerbations which can be life-threatening for<br />

the mother and fetus [37] .<br />

Increased maternal complications, including<br />

pre-eclampsia [61] , gestational diabetes [62] , preterm<br />

labor [63] , intrauterine growth restriction [59] , vaginal<br />

hemorrhage [64] , placenta previa [65] and cesarean<br />

delivery [65] have been described. Adverse fetal<br />

outcomes include increased risk of perinatal<br />

mortality [66] , intrauterine growth restriction [59] and<br />

low birth weight [62] . As early as in 1970, Gordon et<br />

al [66] reported a relatively large number of maternal<br />

or perinatal deaths in asthmatic patients, which were<br />

more likely to occur in severe asthmatics. A Californian<br />

perinatal database study comparing asthmatics to<br />

controls showed that asthmatics were more at risk<br />

of cesarean section, pre-term labour or delivery and<br />

pre-term premature rupture of the membranes. A<br />

cohort of almost 25,000 pregnant females in Canada<br />

found a significant association between pre-eclampsia<br />

and asthma [67] . Greenberger and Patterson [68] found


<strong>December</strong> <strong>2012</strong><br />

KUWAIT MEDICAL JOURNAL 282<br />

that those who had been hospitalized with status<br />

asthmaticus delivered neonates of reduced birth weight<br />

compared with those who were not hospitalized for<br />

asthma, suggesting that an acute attack of asthma may<br />

put the fetus at additional risk, particularly of intrauterine<br />

growth restriction (IUGR).<br />

However, it must be conceded that a few studies<br />

have not found such correlations. Apter et al [69] found<br />

no evidence of an increased rate of pre-eclampsia,<br />

pre-term delivery or IUGR in asthmatic adolescents<br />

compared with general estimates for adolescent<br />

pregnancies. However, these researchers did report<br />

that IUGR was significantly more likely in females<br />

with moderate or severe asthma, who required<br />

hospitalization during pregnancy, compared to<br />

subjects with mild asthma, who were not hospitalized<br />

for asthma during pregnancy. Similarly, Mabie et al [70]<br />

reported no increased rate of pre-term delivery or low<br />

birth weight among asthmatic females compared with<br />

general population rates, which were very high (17.7<br />

and 6.3%, respectively). Likewise, Tata et al [71] reported<br />

an increase in risks of miscarriage and cesarean section<br />

in women with more severe asthma and previous<br />

asthma exacerbation, but not other complications.<br />

Despite the few studies showing a lack of<br />

adverse consequences, a majority of the studies have<br />

demonstrated associations between asthma and preeclampsia,<br />

and asthma and low birth weight by both<br />

historical or prospective cohort and case-control<br />

studies. A meta-analysis of the association between<br />

asthma in pregnancy and low birth weight babies<br />

showed that there was a significantly increased risk of<br />

low birth-weight babies in asthmatic pregnancies and<br />

that there was no significant increase in the risk of low<br />

birth weight with asthma when inhaled corticosteroids<br />

(ICS) were used [59] .<br />

There is therefore, a general agreement that severe<br />

asthma requiring corticosteroid therapy is associated<br />

with an increased incidence of low birth-weight<br />

babies and of preterm births [72-74] . Asthma, when<br />

not treated with inhaled steroids during pregnancy<br />

was associated with changes in placental function<br />

that affect fetal development which includes the<br />

hypothalamic-pituitary axis and growth [16] . In general,<br />

published data suggest that asthma severity, especially<br />

with suboptimal control, is associated with adverse<br />

pregnancy outcomes (Fig. 4) [74] .<br />

PREGNANCY: A Th2-TYPE SITUATION<br />

The fetus can be viewed as a sort of a semiallogeneic<br />

allograft that expresses paternally-derived<br />

antigens, which under non-pregnant circumstances<br />

would result in the activation of a “rejection reaction”.<br />

However, it is postulated that a number of processes<br />

are activated in concert to protect the fetus and thus<br />

ensure its survival. These include the separation<br />

of the maternal and fetal circulations, masking of<br />

paternal antigens on the trophoblast, endocrinological<br />

inhibition of adverse maternal immune reactions and<br />

production of immunomodulatory factors by both the<br />

mother and fetus. In 1993, Wegmann et al proposed that<br />

a shift towards Th2-mediated immunity particularly at<br />

uterine sites during pregnancy inhibits Th1 immune<br />

responses and prevents the rejection of the fetus by the<br />

maternal immune system [75] .<br />

Humoral immune responses are enhanced during<br />

pregnancy, while cell-mediated immune responses<br />

and the course of cell-mediated autoimmune disorders<br />

are down-regulated. Clinical evidence indicates that<br />

pregnant women undergo immunological changes<br />

consistent with a weakening of Th1 responses and<br />

strengthening of Th2 responses [75,76] leading to the<br />

contention that successful pregnancy probably<br />

depends on preferential stimulation of Th2 cytokineproducing<br />

cells. Experiments on mice and evidence in<br />

humans indicate that humoral responses are enhanced<br />

during pregnancy, but that there is a down-regulation<br />

of cell-mediated reactivity, responses to intracellular<br />

infections and the course of cell-mediated autoimmune<br />

disorders. These observations are consistent with a<br />

dampening of pro-inflammatory or Th1 reactivity and<br />

augmentation of anti-inflammatory or Th2 immunity<br />

during pregnancy.<br />

Dudley et al [77] found that cytokine responses by<br />

activated lymphocytes from pregnant mice are marked<br />

by a progressive decline in the production of the Th1<br />

cytokine IL-2 and a concomitant increase in the levels<br />

of the Th2 cytokine IL-4. In humans, there are reports<br />

of significantly higher production of IL-10 (a Th2<br />

cytokine) by mitogen-activated PBMC in pregnant<br />

women as compared with non-pregnant women [78] .<br />

Kruse et al [79] reported significantly reduced IL-2<br />

and IFNγ mRNA expression during normal human<br />

pregnancy and a shift to a pronounced Th2 status.<br />

Using flow cytometric techniques on a single cell,<br />

significantly increased IL-4-producing CD4 + and CD8 +<br />

T cells were demonstrated in normal pregnant women<br />

as compared to non-pregnant women. In contrast,<br />

IFNγ- and IL-2-producing CD4 + and CD8 + T cells were<br />

significantly reduced in pregnancy, which is suggestive<br />

of a Th2 shift in pregnancy [80] . Thus, pregnancy is indeed<br />

a Th2-type phenomenon as proposed by Wegmann et<br />

al [75] and pregnancy seems to engender a shift towards<br />

Th2 bias [76] .<br />

Thus, the two broad lines of evidence described<br />

above show that both asthma and pregnancy are<br />

indeed Th2-type situations. Th2 cells and cytokines<br />

stimulate IgE production and are responsible for the<br />

activation of mast cells and inflammatory responses in<br />

asthma [17-21,23-26] . Likewise, pregnancy is associated with<br />

a dominance of Th2 reactivity and at the same time Th2<br />

reactivity is conducive to successful pregnancy [75,76] .

Asthma during Pregnancy: An Immunologic Perspective<br />

<strong>December</strong> <strong>2012</strong><br />

Interestingly, immune mechanisms involved in the<br />

maintenance of asthma-related symptoms are regulated<br />

by Th2-mediated mechanisms as in normal pregnancy<br />

which leads us to propose that pregnancy may worsen<br />

asthma by bringing about a stronger bias towards Th2<br />

reactivity. However this rather simplistic notion is<br />

complicated by the fact that the disease becomes worse<br />

in only about a third of the patients and, not as one<br />

might predict, in all the patients.<br />

IMMUNE STATUS IN ASTHMATIC WOMEN WHO<br />

BECOME PREGNANT<br />

Pregnancy is proposed to be a state of wide-spread<br />

lymphocyte activation, but at the same time it may<br />

blunt lymphocyte activation which characterizes<br />

bronchial asthma [81] . However, immunological<br />

changes in asthmatic women during pregnancy are<br />

not well elucidated. Tamasi et al [82] reported signs of<br />

pregnancy-induced attenuation of allergic responses<br />

in asthmatic pregnant women. Activated pools within<br />

CD4 + and CD8 + T cells were larger, and the number<br />

of natural killer T (NK-T) cells was increased both<br />

in non-pregnant asthmatic and in healthy pregnant<br />

subjects (compared to non-pregnant healthy controls),<br />

but in well-controlled pregnant asthmatics no further<br />

lymphocyte activation was observed, suggesting<br />

that the immunosuppressive effect of uncomplicated<br />

pregnancy may dull lymphocyte activation which<br />

characterizes asthma. In addition, as a sign of an<br />

enhanced T cell apoptosis, higher numbers of cytotoxic<br />

T cells was detected in healthy pregnant women than in<br />

healthy non-pregnant women, together with a positive<br />

correlation between cytotoxic T cell counts and birth<br />

weights in healthy but not in asthmatic pregnancies. On<br />

the other hand, in another study on poorly-controlled<br />

asthmatic pregnant women, a substantial number of<br />

peripheral IFN-γ-producing cells were detected, and a<br />

significant negative correlation was revealed between<br />

the number of IFN-γ-positive T cells and birth weight<br />

of newborns, suggesting that intrauterine growth<br />

restriction can be related to active, asthma-associated<br />

maternal immune reactions [82] .<br />

Bohacs et al [81] reported an increased prevalence<br />

of regulatory T (Treg) cells in peripheral blood of<br />

healthy pregnant women but a lower prevalence of<br />

Treg cells and an elevated prevalence of NK-T cells<br />

in pregnant asthmatic women compared to healthy<br />

pregnant women. They also reported lower effector /<br />

mem¬ory ratios and higher naive T cell prevalence in<br />

asthmatic pregnant patients compared to non-pregnant<br />

asthmatics [83] .<br />

Analysis of immune cells in the maternal circulation<br />

indicates that circulating white cells are altered in<br />

asthmatics when compared to non-asthmatics and that<br />

these alterations may contribute to worsening asthma<br />

during pregnancy. Maternal circulating monocyte<br />

populations were significantly increased in pregnant<br />

asthmatic women not using inhaled steroids for the<br />

treatment of their disease [84] . Monocytes play important<br />

inflammatory roles in asthma, as the precursors to<br />

macrophages and also through their interaction with<br />

Th2 lymphocytes, eosinophils and mast cells within<br />

the lung. Murphy et al [84] examined placental Th2:Th1<br />

cytokine mRNA ratios and found a significant increase<br />

in placental Th2:Th1 cytokine mRNA ratios in females,<br />

as assessed by measuring TNFα (Th1) and IL-5 (Th2)<br />

mRNA.<br />

A CYTOKINE LINK BETWEEN ASTHMA AND<br />

PREGNANCY<br />

As pregnancy is a Th2-type situation, it is tempting<br />

to predict that symptoms in asthmatic women may<br />

become worse when they get pregnant, because<br />

asthma is also a Th2-type situation. It is a sort of<br />

an “immunological double whammy”! One might<br />

speculate that the Th2 predominance seen in pregnancy<br />

might worsen asthma situations; by corollary then,<br />

all asthmatic women should have worsened asthma<br />

symptoms when they become pregnant. However,<br />

this is not the case; the dogma holds that only about<br />

33% of asthmatic women have worsened symptoms<br />

during pregnancy, while approximately 33% actually<br />

get better!<br />

There is a lack of studies on longitudinal assessment<br />

of cytokine bias during and after pregnancy in<br />

asthmatics that become pregnant as also possible effects<br />

of changes in cytokine patterns on asthma symptoms<br />

during pregnancy. Rastogi et al [85] reported a nonsignificant<br />

trend towards decreased intracytoplasmic<br />

levels of IFNγ and increased IL-4 levels in pregnant<br />

asthmatics. Non-asthmatic pregnant women were not<br />

studied. Interestingly, these researchers demonstrated<br />

a decline in IP-10/eotaxin ratio over the course of<br />

pregnancy; this ratio was also shown to be associated<br />

with worse asthma symptoms. The levels of other<br />

cytokines were not estimated in this study. Clearly this<br />

aspect needs to be investigated further.<br />

Tamasi et al [86] demonstrated increased levels of<br />

IFNγ-producing T cells in pregnant asthmatics as<br />

compared to non-pregnant asthmatics. IL-4-producing<br />

T cells were also increased in number though to a much<br />

lower extent, leading these researchers to conclude<br />

that pregnancy in asthmatics leads to a dominant<br />

IFNγ response. While these results are interesting, it<br />

should be noted that pregnant non-asthmatics were<br />

not compared, nor were other cytokines tested.<br />

CONCLUSION<br />

The jury is still out; as asthma is characterized<br />

by increased Th2 polarization, we suggest that<br />

pregnancy-associated Th2 polarization may contribute<br />

mechanistically to worse birth outcomes. Our


<strong>December</strong> <strong>2012</strong><br />

KUWAIT MEDICAL JOURNAL 284<br />

hypothesis is that asthmatic women who get worse<br />

during pregnancy have a different cytokine profile<br />

as compared to asthmatic women who get better<br />

during pregnancy. We suggest that some asthmatic<br />

women develop a substantially stronger Th2-bias<br />

during pregnancy as compared to other asthmatic<br />

women; and that the former subgroup would have<br />

worsened asthma symptoms than the latter due to<br />

the stronger Th2-bias. Further studies are needed to<br />

elucidate the relationship between immunological<br />

alterations in Th2 polarization and asthma symptoms<br />

during and following pregnancy. Closer monitoring<br />

with early identification and perhaps treatment of<br />

Th2 polarization may in turn lead to reduced asthma<br />

symptomatology and perhaps prevention of asthmarelated<br />

adverse effects on the fetus.<br />

ABSTRACT<br />

Objective: To evaluate the efficacy of intravenous labetalol<br />

versus oral nifedipine in the treatment of severe hypertension<br />

with pregnancy<br />

Design: Prospective, non-randomized<br />

Setting: Department of Obstetrics and Gynecology, Maulana<br />

Azad Medical College and Lok Nayak Hospital, New Delhi,<br />

India<br />

Subjects and Methods: Fifty pregnant patients with severe<br />

hypertension (blood pressure ≥ 160/110 mmHg).<br />

Intervention: The patients were consecutively given either<br />

intravenous labetalol or oral nifedipine.<br />

Main Outcome Measures: The speed and adequacy of<br />

control of blood pressure was compared in both groups<br />

Results: Both drugs were effective in the control of blood<br />

pressure, but nifedipine caused significant reduction of blood<br />

pressure in 20 minutes with a single dose i.e., with the first<br />

dose (p = 0.03). The diastolic blood pressure reduction was<br />

also significant with nifedipine (15.1 ± 6 Vs 8.3 ± 2 mmHg) (p<br />

= 0.03). Average time required was also less with nifedipine<br />

(24 ± 8.2 Vs <strong>44</strong>.21 ± 26.31 minutes, p = 0.006).<br />

Conclusions: Both drugs effectively controlled the blood<br />

pressure in severe hypertension in pregnancy. However,<br />

nifedipine faired better than labetalol in time taken,<br />

reduction of diastolic blood pressure and number of patients<br />

responding with first dose (i.e., in 20 minutes).<br />

KEY WORDS: eclampsia, hypertension, pregnancy, proteinuria<br />

INTRODUCTION<br />

Hypertension in pregnancy is one of the main<br />

causes of maternal deaths in both developed and<br />

developing countries [1] . The main goal of treatment of<br />

hypertension in pregnancy is to safeguard the mother<br />

from the development of acute complications like<br />

cererbro-vascular accidents, eclampsia, target <strong>org</strong>an<br />

damage and maternal mortality while delivering a<br />

healthy infant [2,3] . According to the consensus report<br />

on high blood pressure, the ideal antihypertensive<br />

drug should be potent and safe, rapidly acting,<br />

controllable and without detrimental maternal or<br />

fetal side effects [4] . Labetalol, an α and β adrenergic<br />

blocker, produces rapid dose dependant reduction in<br />

blood pressure by decreasing the peripheral vascular<br />

resistance without causing reflex tachycardia and<br />

fetal distress [5-7] . Labetalol does not reduce cerebral<br />

perfusion and utero-placental blood flow, it has an<br />

anti-platelet aggregation property [8] and a fetal lung<br />

maturation accelerating influence [9] and it also decreases<br />

proteinuria. American College of Obstetricians and<br />

Gynecologists currently recommend labetalol as one<br />

of the first line antihypertensive medications in preeclampsia<br />

[10] . Intravenous labetalol has been available<br />

in India only recently.<br />

On the other hand, nifedipine (calcium channel<br />

blocker) is easily available in India and a less expensive<br />

drug which can also be used in the treatment of severe<br />

hypertension in pregnancy. However, concomitant use<br />

of nifedipine and magnesium sulphate is supposed<br />

to cause neuromuscular blockade [11] , maternal<br />

hypotension and fetal distress. Additionally, nifedipine<br />

has tocolytic effect and reflex tachycardia.<br />

The present study was undertaken to compare<br />

the efficacy of intravenous labetalol for the treatment<br />

of severe hypertension in pregnancy, with nifedipine<br />

administered orally.<br />

SUBJECTS AND METHODS<br />

After institutional and ethical committee approval, a<br />

non-randomized trial was conducted in the Department<br />

of Obstetrics and Gynecology, Maulana Azad Medical<br />

KUWAIT MEDICAL JOURNAL 288<br />

College and associated Lok Nayak Hospital, New<br />

Delhi from <strong>December</strong> 2006 and <strong>December</strong> 2008.<br />

The study included patients selected according to<br />

the criteria given below. Fifty patients were included<br />

in the study.<br />

Inclusion criteria<br />

Pregnancy more than or equal to 20 weeks of<br />

gestation, having severe hypertension i.e., systolic<br />

blood pressure (SBP) of at least 160 mmHg and / or<br />

diastolic blood pressure (DBP) of at least 110 mmHg<br />

with or without proteinuria were included.<br />

Exclusion criteria<br />

Patients with cardiac failure, history of bronchial<br />

asthma, bradycardia (pulse rate < 60 beats per minute),<br />

allergic diathesis and eclampsia were excluded.<br />

After taking history, doing a complete examination<br />

and taking informed consent, either intravenous<br />

labetalol or oral nifedipine were given to the patients<br />

consecutively. Patients were divided into two groups<br />

(i.e., group A - labetalol and group B - nifedipine).<br />

Group A: Twenty fivepatientsreceivedintravenous<br />

labetalol (n = 25), 20 mg intravenous bolus dose<br />

initially, (if not effective within 20 minutes) followed<br />

by escalating doses of 40 mg (2 nd dose), 80 mg (3 rd<br />

dose), 80 mg (4 th dose), and then 80 mg (5 th dose)<br />

every 20 minutes until the therapeutic blood pressure<br />

goal of SBP < 160 mmHg and DBP < 110 mmHg was<br />

achieved or up to a maximum dose of 300 mg or five<br />

doses (Fig. 1).<br />

Group B: Twenty five patients received oral<br />

nifedipine (n = 25), 10 mg oral dose initially, with<br />

repeated doses of 20 mg every 20 minutes until the<br />

therapeutic goal (SBP < 160 mmHg and DBP of < 110<br />

mmHg) was achieved or up to a maximum dose of<br />

90 mg or five doses (Fig. 1).<br />

The patients were then put on oral maintenance<br />

dose of either oral labetalol 100 mg twice daily or<br />

oral nifedipine 10 mg twice daily in addition to a<br />

fixed dose of 250 mg thrice daily of α-methyl dopa<br />

to start with. The dose of labetalol and nifedipine<br />

were titrated to a maximum of 1200 mg of labetalol<br />

or 60 mg of nifedipine in divided doses in the two<br />

groups respectively.<br />

The outcome measures were assessed in terms of<br />

the control of the blood pressure i.e., SBP < 160 mmHg<br />

and DBP < 110 mmHg. The time taken for the control<br />

of blood pressure, the number of doses required was<br />

noted and the patients were observed during the first<br />

two hours.<br />

Statistical analysis<br />

Student’s t test was applied for comparing age,<br />

fall in diastolic blood pressure, fall in systolic blood<br />

pressure and average time required to control blood<br />

pressure between the two groups. Fisher’s Z-test<br />

was used for comparing the proportion of blood<br />

pressure controlled in the two groups by single dose<br />

of individual drug. A p-value of < 0.05 was regarded<br />

as statistically significant<br />

RESULTS<br />

Table 1 shows the demographic data of the two<br />

treatment groups. There were no significant differences<br />

in ages between the two groups. The mean age at<br />

presentation was 24.5 years in group A and 25.35 years<br />

in group B. Seventy five per cent of patients were<br />

the groups were unbooked. Nineteen patients (76%)<br />

of group A and 17 patients (68%) of group B were<br />

pre-eclamptic patients (Table 1). The blood pressure<br />

control was achieved in both the groups fairly well.<br />

In nifedipine group, the control of blood pressure was<br />

achieved in all the patients. In labetalol group, blood<br />

pressure was controlled in 24 out of 25 patients, one<br />

patient who was not controlled with full dose, received<br />

nitroglycerin for control of hypertension. However,<br />

the number of patients controlled with the first dose of<br />

the drug was lower in labetalol group as compared to<br />

nifedipine group (10 / 25 Vs 20 / 25, p = 0.03). Mean<br />

doses requirement of labetalol and nifedipine were<br />

113.4 ± 20 mg and 20.5 ± 10 mg respectively. Mean<br />

SBP reduction of labetalol and nifedipine at first 20<br />

minutes were 14.4 ± 6 mmHg and 18.3 ± 5 mmHg<br />

respectively and there was no significant difference (p<br />

= 0.257) in SBP reduction in both the groups. There was<br />

significant difference (p = 0.03) in reduction of DBP in<br />

first 20 minutes between nifedipine (15.1 ± 6 mmHg)<br />

and labetalol (8.3 ± 2 mmHg) groups (Table 2). The<br />

average time required for control of blood pressure<br />

was <strong>44</strong>.2 ± 26.31 and 24 ± 8.2 minutes in labetalol<br />

and nifedipine groups respectively and there was<br />

significant difference in between the two groups (p =<br />

0.006) (Table 3).<br />

DISCUSSION<br />

Hypertension is one of the most common problems<br />

arising during the pregnancy complicating up to<br />

15% of all pregnancies, and within this disorder,<br />

approximately one in four patients will experience<br />

severe hypertension in pregnancy is mandatory as<br />

it decreases the incidence of maternal intracranial<br />

hemorrhage, hypertensive encephalopathy, abruptio<br />

placentae and maternal mortality. The maternal<br />

mortality from hypertensive disease has been studied<br />

for its attributing factors [13] . There is general agreement<br />

that rapid lowering of high blood pressure can reduce<br />

the maternal risk [14-16] .<br />

Labetalol and nifedipine, both are found to be<br />

safe drugs for the treatment of severe hypertension<br />

in pregnancy from the previous studies [17-20] . Previous<br />

reports [21,22] have indicated that there was apprehension<br />

in nifedipine use as the sublingual variety caused more<br />

sudden decrease in blood pressure, resulting thereby<br />

in overshoot hypotension and ischemia there upon.<br />

The oral variety does not seem to have this [23] effect as<br />

found in our study. There were minimal side effects in<br />

our patients with the use of either drug. No patient had<br />

sudden hypotension below 100 mmHg systolic during<br />

the initial two hours of treatment. Nifedipine achieved<br />

adequate control of blood pressure with only one dose<br />

in 20 / 25 patients whereas in the labetalol group only<br />

10 / 25 patients achieved the control of blood pressure<br />

with one dose, and this difference was statistically<br />

significant (p = 0.03). Both drugs lowered the SBP in the<br />

first 20 minutes by 14.4 ± 6 mmHg and18.3 ± 5 mmHg in<br />

labetalol and nifedipine group respectively and there<br />

was no statistically significant difference between the<br />

two groups. However, there was significant fall in the<br />

blood pressure particularly diastolic with nifedipine<br />

as compared to labetalol in the first 20 minutes. This<br />

is substantiated in other studies by Vermillion et al [20]<br />

and by Raheem et al [24] ; these authors found that the<br />

use of nifedipine was associated with increase in urine<br />

output in addition to rapid control over blood pressure<br />

as compared to labetalol. Whether rapid fall in blood<br />

pressure is beneficial or not is unclear, particularly if<br />

it is not causing cerebral hypoperfusion or overshoot<br />

hypotension or any other adverse effects on the fetus<br />

or the mother.<br />

Nevertheless, the importance of close monitoring<br />

of blood pressure every 20 minutes or earlier as need<br />

arises has to be emphasized as the patient can have<br />

hypotension if the drugs are not adequately titrated.<br />

If the trends of blood pressure over two hours<br />

are carefully observed, it is evident that both drugs<br />

achieved fair control of blood pressure in our study.<br />

Therefore, either drug can be used successfully in<br />

the control of hypertension in pregnancy. The use<br />

of nifedipine for control of severe hypertension in<br />

pregnancy had been proven in earlier studies [25-30]<br />

as well. However, labetalol may be advantageous in<br />

delirious patient because of its intravenous route.<br />

CONCLUSION<br />

Both drugs effectively controlled the blood pressure<br />

in severe hypertension in pregnancy. However,<br />

nifedipine faired better than labetalol in time taken,<br />

reduction of DBP and number of patients responding<br />

with first dose (i.e, in 20 minutes).<br />

Total Hip Replacement in Nigeria: A Preliminary Report<br />

Nwadinigwe Cajetan Uwatoronye, Anyaehie Udo Ego, Katchy Uchenna Amaechi<br />

National Orthopedic Hospital, Enugu (NOHE), Nigeria<br />

Kuwait Medical Journal <strong>2012</strong>; <strong>44</strong> (4): 291 - 296<br />

ABSTRACT<br />

Objectives: The first total hip replacement (THR) in Nigeria<br />

was performed in 1974. But due to infrastructural decay in<br />

public institutions, arthroplasty outcome was poor. National<br />

Orthopedic Hospital, Enugu (NOHE) - a regional trauma<br />

and orthopedic centre took the initiative in 2008. This paper<br />

presents our preliminary results and lists our challenges in<br />

establishing this service in a resource- constrained economy.<br />

Design: Prospective<br />

Setting: NOHE, Nigeria<br />

Subjects: Fifty-two patients who had primary hip arthroplasty<br />

between November 2008 and November 2010<br />

Method: Details of demographic data, joints affected,<br />

etiology, co-morbidities, anesthesia, postoperative treatment,<br />

complications, and follow-up were recorded, analyzed and<br />

challenges noted<br />

Intervention : Total hip replacement<br />

Main Outcome Measures: Improvement in patient’s function<br />

and re-operation rate<br />

Result: Fifty-four THRs were done in fifty-two patients.<br />

Twenty nine (53.7%) patients were male. The mean age<br />

was 52 ± 2.4 years. Two patients had staged bilateral hip<br />

replacement. Twenty five (48.1%) patients had primary<br />

osteoarthritis. The commonest complaint at presentation<br />

was incapacitating hip pain. Half of the patients 26 (49.9%)<br />

had this pain for over four year. Trauma related secondary<br />

arthritis was responsible for 21 cases and old unreduced hip<br />

dislocation in five (9.6%) patients. Six patients had previous<br />

hip surgeries. Implant dislocation occurred in three (5.5%)<br />

patients. The functional status improved in all patients as<br />

shown by Harris Hip scores.<br />

Conclusion: There is an absolute need to develop arthroplasty<br />

service in Nigeria. A good number of the cases were complex<br />

primary arthroplasties. Most of the patients were relatively<br />

young and will outlive their implant.<br />

KEY WORDS: depressed economy, hip arthroplasty, Nigeria<br />

INTRODUCTION<br />

Total hip replacement (THR) is undoubtedly the<br />

most successful procedure in orthopedics [1] . It brings<br />

a new lease of life by pain relief and improvement in<br />

hip function in patients with advanced ostheoarthritis<br />

when conservative management has failed.<br />

Since the work of Sir John Charnley on the hip<br />

arthroplasty in 1960’s, a lot of advances have been seen<br />

in this field of orthopedics [2,3] . The first THR in Nigeria<br />

was performed in 1974 at the University of Nigeria<br />

Teaching Hospital, Enugu. But due to sustained<br />

infrastructural decay in public institutions, the specialty<br />

of arthroplasty was poorly developed even though<br />

indications were there. Hitherto, few patients (who<br />

could afford it) were referred abroad. This practice over<br />

the years was associated with many problems; huge<br />

capital flight, poor patient follow-up and persistent<br />

underdevelopment of the specialty. The vast majority<br />

of patients with end stage osteoarthritis (OA) were<br />

either left to live with their pain and deformity or were<br />

offered arthrodesis or excision arthroplasty.<br />

National Orthopedic Hospital, Enugu (NOHE) - a<br />

regional trauma and orthopedic training center took<br />

the initiative in 2008. To the best of our knowledge, no<br />

coordinated institutional arthroplasty center exists in<br />

Nigeria. The objectives of this paper were to present<br />

our preliminary results and to share our challenges<br />

in establishing this service in a resource- constrained<br />

economy.<br />

SUBJECTS AND METHODS<br />

This was a prospective study of 54 consecutive<br />

THRs done from November 2008 to November 2010.<br />

Details such as demographic data, joints affected,<br />

etiology, co-morbidities, anesthesia, postoperative<br />

treatment, complications, and follow-up were collected<br />

prospectively. The functional level of each patient<br />

was assessed pre and postoperatively, at six months<br />

and one year using Harris hip score. All patients had<br />

preoperative and immediate postoperative X-ray<br />

evaluation. The pre- operative X-rays were classified<br />

based on Kellgren and Lawrence scale for primary<br />

osteoarthritis and Ficat and Arlet for avascular<br />

necrosis (AVN). The X-ray evaluation was repeated<br />

at three months, six months and one year follow-up<br />

as the case may be. All the operations were through<br />

anterolateral approach. The implant consisted of<br />

hydroxyapetite coated titanium femoral stem, 28 mm<br />

cobalt based alloy head and 28 mm UHMWP on<br />

metal shell (Corail Duraloc, DePuy International). All<br />

patients received prophylatic antibiotics - ceftriazone<br />

and metronidazole. Enoxaparin 40 mg daily for five<br />

days and compression bandaging were used for<br />

deep vein thrombosis (DVT) prophylaxis and the<br />

patients were mobilized on the first day post surgery.<br />

The major outcome measures were improvement in<br />

patient’s function and reoperation rate. Data analysis<br />

was done with SPSS software version 11. Descriptive<br />

statistics are provided. The study was approved by<br />

ethical committee of the hospital.<br />

with old unreduced posterior hip dislocation had<br />

posterior wall defect and false acetabulum. All cases<br />

presented to our center more than one year after initial<br />

injury and treatment by traditional bone setters with<br />

uncontained femoral heads; all underwent one-stage<br />

total hip arthroplasty. This group of patients was also<br />

younger with a mean age of 42 ± 2.3 years.<br />

Avascular necrosis of the head of femur from sickle<br />

cell disease was noted in four (7.7%) patients. They<br />

were all stage IV (Ficat and Arlet staging, Fig. 3). Their<br />

mean age was 28 ± 3.4 years. All the sicklers had dense<br />

bone sclerosis and near obliteration of the proximal<br />

femoral medullary canal intraoperatively. One patient<br />

had femoral perforation during reaming. We did not<br />

observe painful postoperative sickling crises. All<br />

patients had oxygen saturation monitored during the<br />

surgery.<br />

Patients had an average pre-operative Harris hip<br />

score of 45 (range of 35 - 47). Twenty-three patients had<br />

co-morbidities. The most common associated medical<br />

problem was uncontrolled hypertension in 14 patients.<br />

The others were diabetes mellitus in four, asthma in<br />

one and peptic ulcer disease in four patients. All the<br />

co-morbidities were well-controlled with medication<br />

before the THR.<br />

Regional block was employed in all the surgeries<br />

except in five cases of failed spinal which were then<br />

converted to general anesthesia. Intra-operative blood<br />

loss varied from 400 ml – 1000 ml (mean blood loss<br />

800 ml). Five patients received intraoperative blood<br />

transfusion, while seven others had postoperative<br />

blood transfusion in the ward.<br />

All the patients were given intravenous antibiotics,<br />

ceftriaxone and metronidazole for five days. They<br />

also received parenteral analgesics for 48 hours before<br />

shifting to oral drugs. Enoxaparin 40 mg daily was<br />

given for five days and compression bandaging was<br />

used for DVT prophylaxis and the patients were<br />

mobilized on the first day post surgery.<br />

The most important complication observed was<br />

implant dislocation in three (5.5%) patients. This<br />

was due to component mal-positioning. Two hips<br />

dislocated while in the hospital and one at home. Three<br />

of them had component repositioning and remained<br />

stable (Table 4).<br />

was slow. They were discharged on partial weight<br />

bearing with bilateral axillary crutches.<br />

Follow up is on-going. Harris hip score at six<br />

months and one year post surgery improved to 90 in<br />

thirty five patients and 80 - 89 in seventeen patients.<br />

Most of them were satisfied with their progress so far.<br />

There was no mortality recorded.<br />

DISCUSSION<br />

Total joint replacement is a well-established<br />

procedure for the hip joint in the developed world.<br />

Although other joints have been replaced with variable<br />

outcome, hip replacement has been adjudged the most<br />

successful orthopedic operation [1] .<br />

In Nigeria, THR is at its infancy [4] although the first<br />

THR in Nigeria was done in 1974. The subspecialty<br />

could not advance due to sustained infrastructural<br />

decay in public institutions and the huge capital<br />

overlay made it an impossible venture for most private<br />

practitioners. Nigeria is a country of 150 million people<br />

with varying health needs. In this study, our patient<br />

population was a mixed bag of primary osteoarthritis<br />

(OA), post- traumatic secondary OA, sickle cell disease<br />

(SCD) etc., and they were relatively young.<br />

We found the mean age of our patients to be 52 ±<br />

2.4 years (range 18 - 78 years) .The import of having<br />

relatively younger patients is that many of them will<br />

outlive their implant and require revision. It has been<br />

shown that patients younger than 50 years at the time<br />

of surgery have a greater chance of requiring a revision<br />

than of dying; those around 58 years of age have a<br />

50:50 chance of needing a revision and in those older<br />

than 62 years the prosthesis will normally outlast the<br />

patient. Patients over 77 years old have a greater than<br />

90% chance of dying than requiring a revision whereas<br />

those around 47 years are on an average twice more<br />

likely to require a revision than die [5] . What this means<br />

for our region is that revision surgery should develop<br />

alongside primary arthroplasty.<br />

Trauma is a known cause of morbidity and mortality<br />

in people under sixty years of age. In our environment<br />

there are many confounding factors to effective trauma<br />

care. Topmost among them are poverty, influence<br />

of traditional bone setters and faith healers. These<br />

were major reasons why hip dislocations were left<br />

unreduced for a reasonable length of time as observed<br />

in the study (Fig. 4).<br />

SCD is prevalent in Nigeria [6] . Children with SCD<br />

were hitherto regarded as curse from the ‘spirit world’<br />

and therefore were not adequately cared for. But with<br />

better understanding and awareness of genetic basis<br />

for this condition and improvement in their care<br />

some are surviving into adulthood. For these young<br />

SCD patients, development of AVN of the hip is one<br />

of the most limiting factors in their lives in terms of<br />

pain, level of activity, and function. We observed this<br />

in our cases. The treatment of these young patients is<br />

therefore, particularly important not only for socioeconomic<br />

and humanitarian reasons, but also because<br />

of their improved life expectancy [7,8] . The cases in this<br />

study had severe adductor contractures. In addition,<br />

sclerotic proximal femur made reaming very difficult<br />

and could hardly accept anything above size 8 stem.<br />

Those who may have this patient population must<br />

be aware of this and make adequate arrangement for<br />

different implant sizes.<br />

Primary OA was a common etiological factor, but<br />

not as common as in studies from the western world [8] .<br />

A number of factors may be responsible for this;<br />

Nigeria, although an oil producing country ranks low<br />

in human development index - life expectancy is low<br />

(47.56 years), and far below the usual age for primary<br />

osteoarthritis; high illiteracy rate results in lack of<br />

awareness about availability of service and low gross<br />

national income per capita of $2,069 compared to the<br />

cost of arthroplasty [9] . These factors either collectively<br />

or singly may account for the low number. Some of the<br />

patients with primary OA have some features of AVN<br />

from prolonged steroid ingestion to relieve pain.<br />

We observed male preponderance in this study.<br />

This is different from reports in literatures which show<br />

female preponderance [8] . There is scepticism on the<br />

part of our female folks on new procedures especially<br />

when it entails excision of a part and replacement with<br />

a foreign material.<br />

Pain relief is the primary indication for THR [4] . In<br />

this study, pain was the most common indication for<br />

surgery. Most of our patients were virtually on daily<br />

non-steriodal anti-inflammatory drugs for over four<br />

years. This was at a great cost for the four patients that<br />

developed peptic ulcer disease.<br />

Simultaneous arthroplasties are increasingly being<br />

performed during one single anesthetic event [10] . Two<br />

patients in this study had bilateral arthroplasty as<br />

staged operations. We were particularly worried about<br />

the effect of prolonged anesthesia and wound infection.<br />

The interval between the operations was three months.<br />

This was particularly beneficial to the patients who<br />

paid out of their pockets.<br />

Regional (spinal) anesthesia was generally welltolerated.<br />

This is particularly useful in the resourcescarce<br />

environment that we worked in; however, the<br />

incidence of post-spinal headache was high. This is<br />

similar to other reports [11] .<br />

We gave all our patients extended antibiotic therapy<br />

for two reasons. We were ‘paranoid’ about infection.<br />

Our theatre does not have laminar air- flow system and<br />

the same theatre is used for routine clean orthopedic<br />

cases. We believe that in addition to the general<br />

measures of ensuring clean theatre environment, 3 - 4<br />

days antibiotic therapy is necessary until the procedure<br />

is well-standardized and facilities upgraded. No case<br />

of serious infection was observed in the cases so far.<br />

Also, the length of hospital stay was long. A number<br />

of reasons were responsible for this. We were unsure of<br />

the home environment for most patients. The team of<br />

physiotherapists needed the time to guide the patients<br />

before discharge. Secondly, some of the difficult case<br />

had marked muscle wasting and required considerable<br />

time for rehabilitation post operation.<br />

The need for deep vein thrombosis (DVT)<br />

surveillance and prophylaxis is well established in<br />

THR. However, the critical issue is the duration [12] . We<br />

gave our patients enoxaparin 40 mg daily for five days<br />

and continued with compression bandaging and lowdose<br />

aspirin. This corresponds to the time most of them<br />

were fully ambulant. The reason for this short duration<br />

regime was cost. We observed no case of overt DVT.<br />

This was surprisingly similar to the low incidence<br />

reported in other studies with extended duration of<br />

treatment [13] , but quite different from studies in the<br />

African-Americans [14] . References on the incidence of<br />

venous thrombo-embolism (VTE) among the blacks are<br />

commonly taken from studies on African- Americans,<br />

because there is dearth of studies among the native<br />

sub-Saharan black Africans. Our observation may be<br />

due to a number of factors. Immobility remains one<br />

of the most important factors for the development<br />

of DVT. Preoperatively, all our patients maintained<br />

their mobility despite extreme pathology and they<br />

were able to mobilize within the first two days post<br />

surgery. Secondly, most of our patients continued with<br />

low dose aspirin and compression bandaging even<br />

after enoxaparin was discontinued. Although there<br />

is strong evidence that the prevalence of VTE varies<br />

significantly among different ethnic / racial groups,<br />

the genetic, physiologic and clinical basis for these<br />

differences remain largely undefined [15] . Our finding<br />

supports the need to determine gene polymorphisms<br />

associated with VTE in Africans [16] .<br />

Posterior implant dislocation was the only major<br />

adverse event recorded and the only reason for reoperation<br />

in two patients and re-admission and reoperation<br />

in one patient. It was noted that the patients<br />

whose implants dislocated were those that had old<br />

unreduced posterior dislocation of the hip with<br />

posterior wall defect and false acetabulum as well. No<br />

mortality was recorded in this study supporting the<br />

low mortality rate associated with this procedure [17] .<br />

Technical difficulties encountered were due to<br />

the fact that our patients presented very late and so<br />

had bone defects, contractures about the joint, disuse<br />

muscles atrophy, limb length discrepancy, etc. The<br />

contractures make for difficult surgery with need to<br />

do a lot of soft tissue releases, thereby increasing post<br />

operative blood loss and operating time.<br />

Some patients who had prior surgeries like<br />

girdlestone arthroplasty or had hardware in situ<br />

following a failed internal fixation of proximal femoral<br />

fracture presented a lot of surgical challenges. Indeed,<br />

some of these cases qualify for revision or complex<br />

primary arthroplasty. As reported by Sathappan,<br />

complex primary total hip arthroplasty (THA) is<br />

defined as primary THA in patients with compromised<br />

bony or soft-tissue states, including but not limited<br />

to dysplastic hip, ankylosed hip, prior hip fracture,<br />

protrusio acetabuli, certain neuromuscular conditions,<br />

skeletal dysplasia, and previous bony procedures<br />

about the hip [18] .<br />

For the conversion of Girdlestone excision<br />

arthroplasty to THR, locating the original acetabulum<br />

without image intensifier was technically challenging.<br />

The dense fibrous tissue was also very bloody. This<br />

could therefore, be regarded as a revision hip.<br />

Conversion to total hip arthroplasty is generally<br />

accepted as the most successful procedure for failure


<strong>December</strong> <strong>2012</strong><br />

KUWAIT MEDICAL JOURNAL 296<br />

of fixation devices in hip fractures [19] . All the affected<br />

patients had a one stage procedure: implant removal<br />

and THR.<br />

Some of the cases had major bone defect that<br />

required bone grafting. In absence of a bone bank, we<br />

overcame this problem by morselizing whatever is left<br />

of the femoral head, which in some cases was badly<br />

degenerated and collapsed.<br />

Blood loss during surgery is often related to the<br />

difficulties encountered. Significant proportion of<br />

our cases was complex primary and six of them had<br />

previous surgical intervention with dense fibrosis.<br />

The average blood loss (both intra-operative and postoperative<br />

period) for our patients was 800 ml. This<br />

compares favourably with values in the literature [20] .<br />

CONCLUSION<br />

There is an absolute need to sustain the development<br />

of arthroplasty service in Nigeria as shown by the<br />

variety of cases presented. A good number of the<br />

cases are complex primary arthroplasty and most of<br />

the patients are relatively young and will outlive their<br />

implant and therefore, require revision. Therefore,<br />

in addition to development of primary procedures,<br />

investment in capacity building for revision procedures<br />

should be started now to bridge the gap.<br />

Towards Prevention of Diabetes in Offsprings<br />

of Type 2 Diabetic Patients<br />

Amal I El-Sharakawy, Abdulrahman A Abdulla, Fatimah Bendhifari<br />

Al-Yarmouk Health Center, Kuwait<br />

Kuwait Medical Journal <strong>2012</strong>; <strong>44</strong> (4): 297 - 302<br />

ABSTRACT<br />

Objectives: To reveal the extent of advice given about<br />

prevention of diabetes by diabetic parents to their children<br />

who had not developed diabetes yet, and reveal its relation<br />

to risk perception, and other parental factors related to<br />

diabetes<br />

Design: Observational cross-sectional prospective<br />

Setting: Al-Yarmouk Primary Health Care Center, Kuwait<br />

Subjects and Methods: Two hundred type 2 diabetic patients<br />

with non-diabetic children were recruited for this study. A<br />

self-administered questionnaire was used to collect data.<br />

Main Outcome Measure: The nature of advice given by<br />

diabetic parents to their non-diabetic children about adopting<br />

a healthy lifestyle to prevent or delay onset of diabetes<br />

Results: Only 40.5% of diabetic patients advised their children<br />

to adopt a healthy behavior that may prevent development<br />

of type 2 diabetes. Giving advice was significantly associated<br />

with young age, not suffering from complications related to<br />

diabetes, recognizing the importance of giving advice and<br />

identifying unbalanced diet as a risk for diabetes. More than<br />

half the studied group recognized lack of exercise (63%),<br />

overeating (70%), and heredity (56.5%) as etiological factors<br />

for diabetes, while 48% recognized unbalanced diet, and only<br />

3% could recognize the risk of diabetes among offspring.<br />

Conclusion: A comprehensive behavioral, social, and physical<br />

environment approach is required to improve risk perception<br />

of etiological factors of type 2 diabetes especially unbalanced<br />

diet, to enable parents to provide an advice to their children<br />

about healthy behavior needed to prevent diabetes.<br />

KEY WORDS: healthy behavior, obesity, parent-child-relation, primary prevention<br />

INTRODUCTION<br />

Diabetes (DM) is considered a major public health<br />

problem not only because of its association with<br />

multiple medical complications, but also because of<br />

a continuously alarming rise in prevalence rate [1] . Its<br />

impact extends beyond the individual to affect health<br />

systems, social systems, and greatly undermines the<br />

economic resources of the whole country. The highest<br />

increase in the rates of the disease is observed mainly<br />

in the rapidly developing countries as the disease is<br />

mainly associated with changes in lifestyles, economic<br />

development and population growth [2] . Recent studies<br />

in Kuwait reveal a prevalence rate of 14.6%. During<br />

2010, Kuwait ranked seventh for diabetes prevalence<br />

among the 216 countries for which data are available<br />

all over the world [3] . What adds to the complexity of<br />

the problem is the reported finding by the International<br />

Diabetes Federation (IDF) that an estimated 93.9%<br />

increase in the rates of DM in the Middle East-North<br />

Africa region during the period 2010-2030 is expected [3] .<br />

The high prevalence of type 2 diabetes in Kuwait, as<br />

well as other countries of Co-operation Council for<br />

the Arab States of the Gulf (GCC), is associated with<br />

higher prevalence of risk factors for this disease.<br />

Multiple risk factors interact to lead to development<br />

of type 2 diabetes. These factors involve mainly genetic<br />

and environmental factors. One primary risk factor is<br />

a family history of diabetes. A considerable amount<br />

of evidence demonstrated that familial aggregation<br />

of diabetes is associated with an inherited defective<br />

gene that renders the individuals at a higher risk of<br />

diabetes [4] . Other environmental and behavioral risk<br />

factors suggested by the IDF include physical activity<br />

that is closely linked to overweight and obesity. Other<br />

non-modifiable factors included age, race, ethnicity,<br />

and gestational diabetes [5] .<br />

Efforts directed towards prevention or delaying<br />

onset of diabetes among the high-risk group depends<br />

mainly on changing or controlling the modifiable<br />

behavioral risk factors of type 2 diabetes, namely,<br />

amount of daily activity or exercise, balanced eating,<br />

and amount of daily consumed food [6] . Diabetic<br />

parents can play an important role in implementing<br />

the preventive programs dealing with these risk factors<br />

through communicating the concepts and importance<br />

of adopting these healthy behaviors to their children<br />

who are actually at a higher risk of developing type 2<br />

diabetes [7] . However, they have first to recognize the<br />

etiological factors of type 2 diabetes and then advise<br />

their children to adopt these behaviors [8] . Review<br />

of the available literature did not reveal any studies<br />

carried out in Kuwait on this subject. Thus the current<br />

study was planned to reveal the extent of giving advice<br />

about prevention of diabetes given by diabetic parents<br />

to their children who had not developed diabetes yet,<br />

and reveal its relation to recognizing the etiological<br />

risk factors, risk perception, and other parental factors<br />

related to diabetes.<br />

Study hypothesis<br />

Recognition by diabetic parents of etiological<br />

factors of diabetes and their risk perception as well as<br />

their physical health status would affect their ability to<br />

advise their children about adopting a healthy lifestyle<br />

to avoid development of diabetes.<br />

SUBJECTS AND METHODS<br />

An observational cross-sectional study design was<br />

adopted for this purpose. The study was carried out<br />

at the Al-Yarmouk Health Center, Kuwait. All patients<br />

with type 2 diabetes aged less than 75 years and having<br />

non-diabetic children aged between 20 and 50 years<br />

were candidates for this study. Those suffering from<br />

mental retardation were excluded. Out of all diabetic<br />

patients attending the health center, only those fulfilling<br />

the entry criteria were included. A total of 231 eligible<br />

diabetic patients were recruited during the study period.<br />

Out of these, 31 patients refused to share in the study<br />

giving a response rate of 86.6%. The study covered the<br />

period from <strong>December</strong> 2011 to April <strong>2012</strong>.<br />

Tools of the study<br />

A specially designed questionnaire was prepared<br />

for this study. It consisted of three parts. Part one dealt<br />

with socio-demographic characteristics of patients<br />

and included: age, sex, nationality, educational level,<br />

family history of diabetes, and living with offspring in<br />

the same house. Part two consisted of four questions<br />

in addition to measuring weight and height and<br />

calculation of body mass index. These four questions<br />

covered the physical status of the patient, namely,<br />

duration of diabetes, type and form of treatment,<br />

whether suffering from complications of diabetes,<br />

and hospitalization related to the disease. Part three<br />

of the questionnaire dealt with risk perception about<br />

diabetes. Four questions dealt with recognizing<br />

etiological factors of diabetes, namely, inactivity (lack<br />

of exercise), overeating, unbalanced diet and heredity.<br />

In addition one question dealt with risk of suffering<br />

from diabetes for offsprings with diabetic or nondiabetic<br />

parents. The main outcome question of this<br />

study was whether the parents actually advised their<br />

children to adopt a healthy lifestyle behavior. Their<br />

opinion about the necessity of giving their children<br />

an advice about adopting healthy behavior was also<br />

verified.<br />

A pilot study was carried out on 20 diabetic patients<br />

(not included in the final study) to test the clarity and<br />

applicability of the study tools.<br />

Data Management<br />

A pre-coded sheet was used. Data were fed to<br />

the computer directly from the questionnaire. The<br />

Excel program was used for data entry. Data entry<br />

was verified before analysis. Body mass index was<br />

calculated according to the following formula: weight<br />

[kg] / (height [meter]) 2 . The WHO recommendation for<br />

classification of BMI was adopted with the following<br />

cut off points: < 18.5 (underweight), 18.5 < 25 (normal<br />

weight), 25 < 30 (overweight), ≥ 30 (obese) [9] .<br />

Statistical analysis<br />

Before analysis; data were imported to the<br />

Statistical Package for Social Sciences (SPSS) version<br />

17 which was used for both data analysis and tabular<br />

presentation. The following statistical measures were<br />

utilized:<br />

Descriptive measures: count, percentage,<br />

arithmetic mean, and standard deviation<br />

Analytic measures: Mann-Whitney test was used<br />

for quantitative variables with non-normal distribution<br />

technique was used to identify significant predictors of<br />

advising offspring after adjusting for the confounding<br />

effect of other variables. The level of significance selected<br />

for this study was a p-value of ≤ 0.05.<br />

All the necessary approvals for carrying out the<br />

research were obtained. The Ethical Committee of the<br />

Kuwaiti Health Science Center and Kuwait Institute<br />

for Medical Specializations (KIMS) approved the<br />

research.<br />

RESULTS<br />

Table 1 shows characteristics of the studied<br />

population. The majority were female (58.0%),<br />

Kuwaiti (75.5%) holding less than a university<br />

certificate (65.6%). The mean age of the whole group<br />

was 56.4 ± 10.7 years, with a mean body mass index<br />

indicating obesity (31.2 + 6.6 kg/m 2 ), and suffering<br />

from diabetes for a mean period of 8.6 + 7.6 years.<br />

Most of the studied diabetics were living with their<br />

offspring (81.0%) and had a positive family history<br />

of diabetes (79.5%). Although, only 22.0% were<br />

receiving insulin yet 63.5% suffered from one or more<br />

complications of diabetes. Those admitted to hospital<br />

due complications of diabetes constituted 22.0% of<br />

the sample.<br />

Table 2 reveals attitude of diabetics and their actual<br />

provision of advice to their offspring about prevention<br />

of diabetes. Just a total of 81 (40.5%) out of the studied<br />

diabetic subjects actually advised them about how to<br />

adopt preventive measures, while two thirds (66.5%)<br />

recognized that it is necessary to give advice to their<br />

offsprings.<br />

Table 3 portrays the relationship between giving<br />

advice about diabetes to offspring and parental<br />

factors. Those holding a university or higher certificate<br />

were more significantly likely to give advice to their<br />

offspring (OR = 1.96, 95% CI = 1.09 – 3.51, p = 0.0236).<br />

Those experiencing diabetic complications significantly<br />

tended not to advice their offspring as only 24.4% of<br />

them passed on this advice compared with 68.5% of<br />

those without complications (OR = 0.15, 95% CI =<br />

0.08 – 0.28, p < 0.001). The same trend was noticed for<br />

those with positive family history of diabetes as only<br />

35.8% of those with positive family history advised<br />

their offspring about diabetes prevention compared<br />

with 58.5% of those with negative family history of<br />

diabetes (OR = 0.39, 95% CI = 0.19 – 0.79, p = 0.0085).<br />

Diabetic patients giving advice to their offspring were<br />

significantly younger than those not giving advice<br />

(52.2 ± 8.7 compared with 59.2 ± 11.1 years, p < 0.001).<br />

Sex, obesity, regimen of treatment, hospital admission<br />

related to diabetes, living with offspring and duration<br />

of diabetes were not significantly associated with<br />

advising offspring about prevention of development<br />

of diabetes.<br />

Table 4 reveals the relationship between actually<br />

advising children about prevention of and recognition<br />

of etiological factors of diabetes. Univariate analysis<br />

showed that recognizing lack of exercise (OR = 2.53,<br />

95% CI = 1.36 – 4.71, p = 0.003), unbalanced diet (OR =<br />

2.37, 95% CI = 1.26 – 4.46, p = 0.0069), risk perception<br />

of diabetes (OR = 7.87, 95% CI = 0.90 – 68.66, p =<br />

0.0291), and necessity of giving advice about diabetes<br />

prevention to offspring (OR = 47.55, 95% CI = 11.16<br />

– 202.49, p < 0.001) are significantly associated with<br />

actually advising offsprings about diabetes. The only<br />

etiological factor that was not significantly associated<br />

with offspring advising was overeating (OR = 1.39, 955<br />

CI = 0.74 – 2.61, p = 0.3008).<br />

Towards Prevention of Diabetes in Offsprings of Type 2 Diabetic Patients<br />

<strong>December</strong> <strong>2012</strong><br />

Table 5 shows significant predictors of giving<br />

advice to offspring using stepwise forward likelihood<br />

multiple logistic regression. The first step for<br />

identifying the significant predictors was entering all<br />

the independent variables to the model. In the second<br />

step, all variables with 0.10 or less p- value were entered<br />

into a stepwise forward likelihood multiple logistic<br />

regression model. After adjusting for the confounding<br />

factors, only four factors proved to be significantly<br />

predicting advising offspring about diabetes. These<br />

factors included recognizing the importance of giving<br />

the advice as well as unbalanced diet as an etiological<br />

factor of diabetes. Young age and not suffering from<br />

diabetes complications proved to be significantly<br />

associated with advising offspring after adjusting for<br />

the confounding factors.<br />

DISCUSSION<br />

The growing diabetes pandemic that is spreading<br />

all over the world necessitates more attention and<br />

rapid effective programs to control its impact. A<br />

wide spectrum of interventions to prevent diabetes<br />

or delay its onset as well as control its complications<br />

is available. The feasibility and effectiveness of these<br />

interventions varies widely. Although communicating<br />

the potential risks of diabetes and recognition of the<br />

behavioral factors that may be closely linked to the<br />

disease is the main responsibility of the primary health<br />

care staff, parents can play an active role to educate<br />

their children who are at higher risk for developing<br />

type 2 diabetes [10] . Recent studies have illustrated the<br />

potential for intervention in persons with impaired<br />

glucose tolerance to reduce progression to type 2<br />

diabetes. A study in the United States showed that<br />

lifestyle intervention (diet and exercise) reduced the<br />

risk of this progression by 58% [11] . Two other large-scale<br />

studies from China [12] , and Finland [13] demonstrated<br />

effects similar to the American study. In the Finnish<br />

study, the cumulative incidence of diabetes after four<br />

years was 11% in the intervention group and 23% in the<br />

control group. During the trial, the risk of diabetes was<br />

reduced by 58% (p < 0.001) in the intervention group,<br />

and was directly associated with changes in lifestyle.<br />

Proper risk perception of diabetic parents and<br />

adopting a positive attitude toward prevention of<br />

diabetes among their offspring can urge them to educate<br />

their children and guide them to adopt a healthy<br />

behavior. Thus, the current study was formulated to<br />

investigate the factors that can stimulate parents to<br />

advise their offsprings about diabetes prevention and<br />

the factors affecting the giving of this advice. Several<br />

studies were carried out in Kuwait to reveal knowledge<br />

of diabetic patients about etiological risk factors and<br />

management procedures to deal with the disease. One<br />

study revealed that mean score for the total knowledge<br />

test was 58.9% [14] . Knowledge deficits were apparent in<br />

the questions related to diet and self-care.<br />

One study carried out in Japan revealed that<br />

diabetic disease status was related to giving advice.<br />

Use of insulin or oral treatment and the presence<br />

of complications were related to giving advice [7] .<br />

However, the results of this study revealed that<br />

patients with complications were less likely to advise<br />

their children (OR = 0.15, 95% CI =0.08-0.28). The same<br />

trend was noticed for family history as those with<br />

positive family history were also less likely to advise<br />

their children (OR = 0.39, 95% CI = 0.19-0.79). The<br />

absence of complications might be due to adopting<br />

effective techniques and behavior that might stimulate<br />

them to advise their children to adopt these successful<br />

lifestyles. Also, a negative family history which means<br />

that the diabetic parent is the only person in the family<br />

with diabetes might make them feel that they have a<br />

greater responsibility toward advising their children.<br />

Delaying the onset of type 2 diabetes depends<br />

essentially on implementing successful lifestyle<br />

intervention strategies [15] . Cognitive and behavioral<br />

strategies have been used to reduce weight through<br />

dietary restriction and increased physical activity [16] .<br />

However, to be able to implement these healthy<br />

behaviors; diabetic patients must first recognize<br />

the importance as well as the role of these factors in<br />

preventing diabetes. However, the association between<br />

risk perception and behavior has been inconsistent;<br />

while some studies revealed a positive association<br />

between risk perception and health behaviors [17] , other<br />

studies failed to demonstrate this association [18] . This<br />

might be attributed to the poorly specified relationship<br />

between behavior and risk perception. Also, other<br />

factors may affect relationship such as knowledge of<br />

diabetes factors, perceived personal control, or the<br />

degree to which one believes that risk is modified by<br />

one’s action, and optimistic bias, or one’s assessment<br />

of their risk compared with others like them [19] .<br />

One finding about risk perception revealed by this<br />

study is the very low recognition of the probability<br />

of children to develop type 2 diabetes in presence of<br />

positive family history when compared with negative<br />

history. Similar findings were revealed by a Korean<br />

study among offspring of diabetic parents where only<br />

9.9% of the study children could correctly perceive<br />

their risk of developing diabetes [20] .<br />

Multiple logistic regression revealed that young<br />

age, not experiencing complication related to diabetes,<br />

and recognizing the importance of the role of healthy<br />

behavior in preventing diabetes development as well<br />

as specifically recognizing the role of unbalanced<br />

diet are significant predictors for advising children.<br />

In Japan, a similar study dealing with passing of<br />

advice to children revealed that being male, living<br />

with offspring, hospitalizations related to diabetes,<br />

suffering from complications, risk perception, and


<strong>December</strong> <strong>2012</strong><br />

KUWAIT MEDICAL JOURNAL 302<br />

recognizing the role of lack of exercise as an etiological<br />

factor for diabetes proved to be significantly associated<br />

with giving advice to children in the multiple logistic<br />

regression [7] . The differences between the two studies<br />

might be attributed to the difference in culture and<br />

the high prevalence of factors such lack of activity and<br />

obesity.<br />

Although this study dealt with a relatively large<br />

number and a high response rate, yet, due to the<br />

nature of the study, some limitations can be identified.<br />

These limitations include dealing only with a sample<br />

from one primary health care center which might<br />

undermine generalization of the results. The study is<br />

a cross-sectional one, while perception of risk would<br />

be more appropriately a longitudinal study. Thus, it<br />

is recommended that a large study sample involving<br />

diabetic patients representing the whole state of<br />

Kuwait be undertaken in order to confirm the results<br />

of this study.<br />

CONCLUSION<br />

The findings of the current study illustrate the<br />

need to improve the knowledge and perception of<br />

type 2 diabetic patients about the etiological factors of<br />

diabetes as well as perception of risk of development<br />

of diabetes among their offsprings. It is essential<br />

to encourage parents to advise their children to<br />

adopt healthy lifestyle behavior. In this context, a<br />

comprehensive approach that addresses behavioral,<br />

social, and physical environment interventions is<br />

expected to achieve the required outcomes. Proper risk<br />

communication from primary health care workers to<br />

parents and their children needs more attention in the<br />

primary health care units.<br />

ABSTRACT<br />

Objectives: To present the results of our experience with<br />

stereotactic surgery, which is a safe and minimally invasive<br />

technique, in the field of neurosurgery.<br />

Design: Prospective study<br />

Settings: Department of Neurosurgery, Ibn Sina Hospital,<br />

Kuwait<br />

Subjects and Methods: Forty patients underwent stereotactic<br />

surgery for diagnostic and therapeutic purposes during<br />

the five years between 2006 and 2011. There were 26 male<br />

and 14 female patients with a mean age of 47 years (range<br />

9 – 70 yrs). Twenty seven (67.5%) patients had diagnostic<br />

brain procedures and 13 (32.5%) had diagnostic as well<br />

as therapeutic procedures. The stereotactic surgery was<br />

carried out with the help of computerized tomography (CT)<br />

- guided Leksell stereotactic frame® and Leksell SurgiPlan®<br />

software.<br />

Intervention: Stereotactic surgery<br />

Main Outcome Measures: Outcome of surgery and<br />

complications<br />

Results: Stereotactic biopsies confirmed 28 (70%) patients<br />

with brain tumors; six (14%) with cerebral infections, four<br />

(10%) with multiple sclerosis and one with cerebral infarction.<br />

Stereotactic aspirations were performed in nine patients;<br />

four with cystic brain tumors and five with brain abscesses.<br />

Stereotactic insertion of Ommaya reservoir was performed in<br />

four patients with cystic brain lesions. Complication, related<br />

to the procedure was observed only in one patient and was<br />

managed conservatively. No other morbidity or mortality<br />

was noted.<br />

Conclusions: Stereotactic surgery is a minimal invasive<br />

technique that helps the neurosurgeon in further planning<br />

of an appropriate treatment after tissue biopsy. It can also<br />

be used as primary mode of treatment in patients with brain<br />

abscesses, cysts and intracranial hematomas.<br />

KEY WORDS: brain abscess, brain tumors, minimally invasive surgery, stereotactic surgery<br />

INTRODUCTION<br />

Most neurosurgical patients can be diagnosed<br />

correctly on the basis of the natural history of their brain<br />

disorders and after clinical, laboratory and imaging<br />

findings but in some cases, diagnosis is difficult and<br />

the treatment is based on presumptive diagnosis.<br />

Stereotactic surgery is an image-guided technique<br />

which is used to detect the nature of lesion and decide<br />

about the appropriate treatment plan. This technique<br />

is used for an accurate localization of anatomical or<br />

pathological brain structures in three-dimensional (3-<br />

D) space.<br />

Leksell stereotactic system is unique for its<br />

simplicity, accuracy and versatility [1] . It is light weight<br />

frame and all three (x, y and z) coordinates can be<br />

calculated quickly from a 2-dimensional image<br />

without a computer. Stereotactic biopsy is used as<br />

a diagnostic tool to obtain tissue samples that are<br />

suspicious for tumors, infections, infarctions or other<br />

brain pathologies like neurodegenerative disease.<br />

This is the most accurate method of taking biopsies<br />

in deep or highly functional areas of the brain and in<br />

patients with multiple brain lesions or in medically<br />

compromised patients with minimal morbidity and<br />

mortality [2-4] .<br />

Stereotactic aspiration is a valuable procedure in<br />

this field for the primary treatment of different brain<br />

tumors like gliomas (cystic part), craniopharyngiomas [5]<br />

and colloid cysts [6-7] .<br />

Stereotactic drainage is also a treatment of choice<br />

for brain abscesses. Kondziolka et al [8] treated 16<br />

patients with deeply located brain abscesses using this<br />

technique for diagnosis and abscess drainage. Lunsford<br />

et al [9] reported good results with overall bacteriologic<br />

identification of 97% and cure rates of 72% in patients<br />

with brain abscesses. Stereotactic aspirations of<br />

intracerebral hypertensive hemorrhages (acute or<br />

subacute) have shown encouriging results [10] . Catheter<br />

reservoirs may be implanted into the hematoma,<br />

followed with streptokinase or tissue plasminogen<br />

activator injections to lyse the clot [11] .<br />

Although it is a minimally invasive technique, yet<br />

complications have been reported. Sometimes, sample<br />

of the brain tissue taken for biopsy may be nondiagnostic<br />

and may warrant a repeat biopsy. Other<br />

risks include intracranial hemorrhage, infection or<br />

seizures.<br />

Appuzo et al [12] reported 1% morbidity (intracranial<br />

hemorrhage, infection, increased neurological deficit<br />

and seizures) and 0.2 % mortality. Lunsford et al [13]<br />

reported postoperative complications in 2.9% (77)<br />

patients in a series of 2651 patients who underwent<br />

different stereotactic procedures. Out of those,<br />

intracranial hemorrhage occurred in 55 (2.07%)<br />

patients; 11 (0.41%) had local infections at pin sites;<br />

11 (0.41%) patients had post-procedural seizures.<br />

Two (0.075%) patients died from the complications of<br />

the procedure. Although some centers are currently<br />

migrating to frameless stereotactic procedures, their<br />

complication rates are yet to be reported [13] .<br />

PATIENTS AND METHODS<br />

Between 2005 and 2011, we have managed 40<br />

patients with stereotactic surgery. The patients were<br />

selected on the basis of following diagnostic and<br />

therapeutic indications.<br />

Diagnostic<br />

1. Tumors not correlating with their natural history<br />

2. Multiple brain lesions<br />

3. Small and deeply located tumors<br />

4. Patients in good clinical condition (Karnofsky score<br />

> 70)<br />

Therapeutic<br />

5. Cystic lesions that need aspiration<br />

6. Intracranial abscesses<br />

The mean age of the patients was 47 years (range 9<br />

- 70 years). There were 26 male and 14 female patients.<br />

Most of the patients presented with occasional<br />

headaches followed by nausea. Five patients<br />

presented with focal seizures and 12 with neurological<br />

deficits. Twenty patients had lesions, located in the<br />

supratentorial region, 12 in the thalamic and basal<br />

ganglia area, two in the suprasellar region and seven<br />

had multiple intracranial lesions. Stereotactic surgery<br />

was performed with computed tomography (CT)/<br />

magnetic resonance imaging (MRI) - guided Leksell<br />

stereotactic system® and Leksell SurgiPlan® software<br />

v2.20. The procedure started with fixation of Leksell<br />

frame to the head after conscious sedation and local<br />

anesthesia (Fig. 1). All the patients underwent CT<br />

scan with contrast after the attachment of the fiducial<br />

box to the frame. All the brain images were exported<br />

to the computer workstation through Dicom system.<br />

anesthesia, the patient’s head was fixed onto the<br />

Mayfield skull clamp. An arc of the stereotactic system<br />

was attached to the base ring of Leksell frame and<br />

positioned according to the calculated coordinates<br />

so that its center coincides with the selected brain<br />

target. The choice of entry point is free and can be<br />

reached from any direction without the need of<br />

computer calculation (Fig. 2). It depends upon the<br />

location, size, and consistency and the intervening<br />

neural and vascular structures. The entry point should<br />

minimize the length of passage through the brain<br />

and avoid eloquent areas. At the point of entry, a<br />

small skin incision is given, a burr hole is made and<br />

the dura opened to allow visualization of the cortex.<br />

It provides complete freedom of choice of trajectory<br />

and entry point selection. The specimen is taken from<br />

the selected target with the help of biopsy needle and<br />

stored in a bottle with formalin solution and sent for<br />

histopathology. The frame is removed and the patient<br />

is sent for CT scan of brain to rule out any postoperative<br />

complication like hemorrhage and is then transferred<br />

to the recovery room.<br />

therapy. The patient with brain metastasis was further<br />

investigated and his origin of the primary disease was<br />

found to be in the lungs. The patient was referred to<br />

radiation oncologist for further management.<br />

Stereotactic drainage of the intracranial abscess<br />

was performed in five patients. Pus was sent for<br />

culture sensitivity and postoperatively, patients<br />

were managed conservatively with antibiotics.<br />

Post surgical imaging showed reduction in size of<br />

the abscess cavities and clinically all the patients<br />

improved.<br />

Post-operative complication occurred in one<br />

patient. This was asymptomatic hemorrhage after<br />

tissue biopsy which was managed conservatively.<br />

There was no other procedure-related morbidity or<br />

mortality.<br />

DISCUSSION<br />

Stereotactic surgery has been recognized since<br />

many decades after the use of freehand biopsy<br />

techniques resulted in too many postoperative<br />

complications [14-16] .<br />

Stereotactic surgery either for diagnosis or<br />

treatment provides us precision, accuracy and safety<br />

to localize the target in the brain. Stereotactic biopsy<br />

stresses the importance of histological diagnosis<br />

with low morbidity and zero mortality. Many reports<br />

are published in the literature on the safe use of this<br />

technique and a tissue diagnosis is always required<br />

prior to treatment for most cerebral lesions. In their<br />

early experience, Lunsford et al [17] published results of<br />

102 patients with brain disorders who were referred<br />

to University of Pittsburgh for surgical exploration,<br />

using CT-guided stereotactic system. All the patients<br />

were referred because of critical size and location of<br />

the lesions in brain. Diagnostic stereotactic biopsy<br />

demonstrated diagnosis in 98 (96.1%) patients.<br />

Direct therapeutic intervention using this technique<br />

was possible in 26 (25.5%) patients. There was no<br />

morbidity and mortality seen in this early series.<br />

According to them, histological diagnosis must be<br />

sought in all patients with symptomatic brain lesions<br />

regardless of their size or location and “Empiric”<br />

forms of therapy are no longer justified in the age<br />

of CT scanning. Lunsford et al[ 18] reported another<br />

series of 39 patients with craniopharyngiomas who<br />

underwent multimodality stereotactic techniques.<br />

Cystic craniopharyngiomas were treated successfully<br />

with stereotactic implantation of radioactive P32 in<br />

the cystic cavity of the tumor. The success rate was<br />

96%. Kondziolka et al [9] reported a series of 29 patients<br />

with brain abscess. Out of these, 22 (76%) patients had<br />

stereotactic abscess drainage with purulent centers<br />

and seven (24%) patients underwent lesion biopsy<br />

for diagnosis. Twelve patients with large abscesses of<br />

diameter > 3 cm, underwent stereotactic insertion of<br />

drainage catheters. Long-term clinical and imaging<br />

follow-up confirmed disease resolution in 21 patients<br />

(72%) and eventual abscess resolution occurred<br />

in an additional six patients (21%), who required<br />

multiple procedures. Lakecivic et al [19] published an<br />

article to differentiate the results of survival and<br />

outcome of patients with malignant brain gliomas<br />

who were treated by different modes. The control<br />

group of 21 patients had undergone craniotomy and<br />

surgical excision, followed by oncological protocol<br />

while the case group of 11 patients underwent<br />

stereotactic biopsy followed by oncological protocol.<br />

The majority of patients diagnosed by a stereotactic<br />

biopsy survived for more than two years. The<br />

survival and outcome for the patients in whom a<br />

stereotactic biopsy was performed were notably<br />

better compared to the patients who were diagnosed<br />

after surgical excision. Consequently, it appears<br />

that a stereotactic biopsy is a better option for<br />

primary treatment of patients with malignant brain<br />

gliomas when the survival and quality of life are<br />

concerned. Broggi et al [20] published their experience<br />

in 35 patients who underwent stereotactic biopsy<br />

for deeply located lesions. According to them, the<br />

biopsies confirmed the diagnosis based on clinical<br />

and imaging findings in 25 patients but in 10 patients<br />

the histological diagnosis was different from the<br />

presumptive one. The treatment option was changed<br />

in these ten patients. Ostertag et al [4] reported their<br />

experience with 302 cases of stereotactic biopsy and<br />

advocated that exploratory craniotomies, risky freehand<br />

punctures and aspirations deep in the brain<br />

should not be done without prior diagnosis.<br />

Our report emphasises the importance of<br />

histological diagnosis to avoid the hazards of<br />

treatments based on clinical and radiological<br />

findings. Only one of 40 patients had complication,<br />

which shows safety profile of frame based stereotactic<br />

surgery.

ABSTRACT<br />

Objective: Therapeutic efficacy of dendritic cell-based<br />

vaccine for renal cell carcinoma remains limited. In this study,<br />

we investigated whether anti-CD137 monoclonal antibody is<br />

capable of potentiating anti-tumor effect of dendritic cellbased<br />

vaccine.<br />

Design: Experimental study<br />

Setting: Research laboratory<br />

Subjects: Balb/c mice (8-10 weeks old)<br />

Interventions: A renal cell carcinoma model was established by<br />

subcutaneous injection of Renca tumor cells into Balb/c mice<br />

on day 0. After three days, tumor-bearing mice were treated<br />

with Renca tumor lysate-pulsed dendritic cells (i.e., dendritic<br />

cell-based vaccine), anti-CD137 monoclonal antibody, or<br />

combination of Renca tumor lysate-pulsed dendritic cells with<br />

anti-CD137 monoclonal antibody. Mice were killed on day 20<br />

after tumor cell inoculation, and spleens were harvested for<br />

analysis of anti-tumor immune responses.<br />

Main Outcome Measures: The anti-tumor immune responses<br />

were analyzed by measuring proliferation and activity of T<br />

cells, which have the ability to kill tumor cells. The anti-tumor<br />

effect was assessed by measuring tumor size.<br />

Results: The combination therapy with Renca tumor lysatepulsed<br />

dendritic cells and anti-CD137 antibody significantly<br />

increased T-cell proliferation and activity, and significantly<br />

inhibited tumor growth, compared with a single treatment<br />

with Renca tumor lysate-pulsed dendritic cells or anti-CD137<br />

antibody.<br />

Conclusion: These results suggest that combination therapy<br />

can enhance anti-tumor effect by increasing T-cell proliferation<br />

and activity.<br />

INTRODUCTION<br />

Human renal cell carcinoma accounts for<br />

approximately 2 - 3% of all adult cancers [1] . It has<br />

the third highest mortality rate among genitourinary<br />

malignancies, with an estimated 12,000 deaths per<br />

year [1,2] . Incidence rates for renal cell carcinoma have<br />

been increasing continuously by 2 - 3% per year [1,2] .<br />

More than 30% of renal cell carcinoma patients have<br />

metastatic disease at the time of diagnosis, thereby<br />

losing the chance of an operation [3] . In addition, 30%<br />

of patients with primary localized renal cell carcinoma<br />

will subsequently develop metastatic spread after<br />

radical nephrectomy [4] . Metastatic renal cell carcinoma<br />

is resistant to conventional therapies, such as<br />

chemotherapy and radiotherapy [5] . As a result, these<br />

patients with metastatic renal cell carcinoma have a<br />

poor prognosis with 2-year survival rate of < 20% [6] .<br />

The spontaneous regression of metastases has been<br />

reported in 1 - 6% of metastatic renal cell carcinoma<br />

patients [7] . Furthermore, many studies have revealed<br />

infiltration of renal cell carcinoma tissue with T<br />

lymphocytes and dendritic cells [8] . These findings<br />

suggest that immune system plays an important role in<br />

controlling renal cell carcinoma growth. Therefore, the<br />

present treatment strategy for renal cell carcinoma is to<br />

stimulate the patient’s immune system to increase antitumor<br />

immune response by using immunostimulatory<br />

cytokines, such as interferon-α and interleukin-2 [9] .<br />

Clinical trials have shown that cytokine therapy with<br />

interferon-α and interleukin-2 can produce objective<br />

responses in 10 - 15% of patients, but is associated with<br />

severe toxicity [4,10] . Hence, new immunotherapeutic<br />

approaches with more effective anti-tumor activity<br />

and less toxicity are urgently required.<br />

The recent trend in cancer immunotherapy has been<br />

directed toward dendritic cell-based vaccine. It can<br />

induce anti-tumor immune response by activation of<br />

tumor-specific T lymphocytes [11] . In 14 clinical studies,<br />

197 patients with metastatic renal cell carcinoma<br />

underwent therapy with dendritic cell-based vaccine [12] .<br />

According to the World Health Organization criteria,<br />

clinical responses to vaccine are defined as follows [13] .<br />

Complete response means complete disappearance<br />

of tumor; partial response means ≥ 50% decrease in<br />

tumor size without the appearance of new metastases;<br />

stable disease means < 50% decrease or < 25% increase<br />

in tumor size; and progressive disease means ≥ 25%<br />

increase in tumor size or the appearance of new<br />

metastases. Out of the 197 patients, 73 (37%) had clinical<br />

response with four complete responses, eight partial<br />

responses and 61 disease stabilizations [12] . Only mild<br />

side-effects, such as low-grade fever, fatigue, diarrhea,<br />

flulike symptoms, and local reactions around the<br />

injection site, were observed in these patients. Though<br />

dendritic cell-based vaccine had encouraging results<br />

in the treatment of metastatic renal cell carcinoma,<br />

clinical response rate remained limited. Dendritic cellbased<br />

vaccine was administered in combination with<br />

interleukin-2 to treat patients with metastatic renal<br />

cell carcinoma in order to improve vaccine efficacy [14] .<br />

However, clinical response rate was 40%, similar to<br />

single treatment with dendritic cell vaccine. Therefore,<br />

new approaches to significantly increase vaccine effect<br />

are needed.<br />

The CD137 (4-1BB), a member of tumor necrosis<br />

factor receptor (TNFR) superfamily, is an inducible costimulatory<br />

molecule expressed primarily on activated<br />

T cells [15] . Ligation of CD137 by anti-CD137 monoclonal<br />

antibody delivers a potent co-stimulatory signal to T<br />

cells, and enhances proliferation and activity of T cells,<br />

which have the ability to kill tumor cells [16] . Previous<br />

study has demonstrated that treatment of tumorbearing<br />

mice with anti-CD137 antibody can result in<br />

T cell-mediated tumor rejection [17] . We hypothesized<br />

that anti-CD137 antibody may potentiate anti-tumor<br />

effect of dendritic cell-based vaccine. The reason is as<br />

follows. Treatment with dendritic cell-based vaccine<br />

induces up-regulation of CD137 expression on T cells<br />

by activating T cells. Subsequent administration of anti-<br />

CD137 antibody further increases T cell proliferation<br />

and activity through ligation of CD137 on T cells,<br />

thereby strengthening anti-tumor effect. To confirm<br />

this hypothesis, we investigated the combined effect of<br />

dendritic cell-based vaccine with anti-CD137 antibody<br />

in renal cell carcinoma mouse model.<br />

MATERIALS AND METHODS<br />

Animals<br />

Balb/c mice, 8 - 10 weeks of age, were obtained<br />

from Shanghai Laboratory Animal Center (Shanghai<br />

City, China) and maintained under specific pathogenfree<br />

conditions. They were provided with sterilized<br />

food and water ad libitum. All animal experiments<br />

were conducted in accordance with the US National<br />

Institutes of Health guidelines for appropriate use<br />

of experimental animals and approved by Animal<br />

Research and Care Committee at our university.<br />

Preparation of dendritic cell-based vaccine<br />

Dendritic cell-based vaccine was prepared as<br />

described by Lim et al [18] . In brief, bone marrow cells<br />

of Balb/c mice were cultured in complete medium<br />

supplemented with 10 ng/ml recombinant mouse<br />

granulocyte macrophage colony-stimulating factor<br />

(R & D Systems, Minneapolis, MN, USA) and 10 ng/ml<br />

recombinant mouse interleukin-4 (R&D Systems,<br />

Minneapolis, MN, USA). Complete medium consisted<br />

of RPMI-1640 containing 10% heated-inactivated fetal<br />

bovine serum, 2 mmol/l L-glutamine, 100 units/ml<br />

penicillin and 100 μg/ml streptomycin (all from Life<br />

Technologies, Grand Island, NY, USA). On day two,<br />

suspended cells were removed and adherent cells<br />

were cultured in fresh complete medium containing<br />

cytokines. Half of the medium was replaced with<br />

fresh medium containing cytokines every other day.<br />

On day seven, nonadherent and loosely adherent cells<br />

(i.e., immature dendritic cells) were harvested. The<br />

Balb/c-derived renal cell carcinoma cell line (Renca)<br />

was obtained from American Type Culture Collection<br />

(Manassas, VA, USA) and suspended in phosphatebuffered<br />

saline. Renca tumor cell lysate was prepared<br />

by four rapid freeze-thaw cycles (liquid nitrogen,<br />

37 °C water bath). In order to induce dendritic cell<br />

maturation, immature dendritic cells were incubated<br />

with Renca tumor cell lysate at the ratio of three tumor<br />

cells lysate to one dendritic cell in complete medium.<br />

After 8 hours, 10 ng/ml recombinant mouse tumor<br />

necrosis factor-α (R & D Systems, Minneapolis, MN,<br />

USA) and 10 ng/ml recombinant mouse interferon-γ (R<br />

& D Systems, Minneapolis, MN, USA) were added<br />

to induce dendritic cell further maturation. After<br />

incubation for 16 hours, Renca tumor lysate-pulsed<br />

dendritic cells (i.e., mature dendritic cells) were<br />

harvested and used as dendritic cell-based vaccine in<br />

our study. Dendritic cells were evidenced by phenotype<br />

analysis.<br />

antibody (BD PharMingen, San Diego, CA, USA)<br />

and phycoerythrin-labeled anti-CD83 (maturation<br />

marker of dendritic cells) monoclonal antibody (BD<br />

PharMingen, San Diego, CA, USA), and then analyzed<br />

by flow cytometry for expressions of CD11c and CD83<br />

on the cell surface.<br />

Analysis of CD137 expression on T cells<br />

Spleens from Balb/c mice were prepared as cell<br />

suspensions. T cells were isolated from splenocytes<br />

by the use of T cell separation reagents (Miltenyi<br />

Biotec,Auburn, CA, USA). Purified T cells (1 × 10 5 /<br />

well) were cultured alone or with Renca tumor lysatepulsed<br />

dendritic cells (1 × 10 4 /well) in round-bottom<br />

96-well plates, harvested at 24-hour intervals for 7 days,<br />

and stained with fluorescein isothiocyanate-labeled<br />

anti-CD3 (T-cell marker) monoclonal antibody (BD<br />

PharMingen, San Diego, CA, USA) and phycoerythrinlabeled<br />

anti-CD137 monoclonal antibody (BD<br />

PharMingen, San Diego, CA, USA). CD137 expression<br />

on T cells was analyzed by flow cytometry.<br />

Tumor implantation and treatment<br />

The Balb/c mice were inoculated subcutaneously<br />

in the right flank with 5 × 10 5 Renca tumor cells on day<br />

0. After three days, tumor-bearing mice were randomly<br />

divided into four groups. Control group received no<br />

treatment. In dendritic cell-treated group, mice were<br />

immunized subcutaneously in the left flank with<br />

Renca tumor lysate-pulsed dendritic cells (1 × 10 6 ) on<br />

days 3 and 10 [18] . Mice in antibody-treated group were<br />

injected intraperitoneally with anti-CD137 monoclonal<br />

antibody (100 μg; R & D Systems, Minneapolis, MN,<br />

USA) on days 3 and 10. Combination therapy group<br />

received both subcutaneous injection of Renca tumor<br />

lysate-pulsed dendritic cells (1 × 10 6 ) on days 3 and<br />

10, and intraperitoneal administration of anti-CD137<br />

monoclonal antibody (100 μg) on days 6 and 13. The<br />

maximal perpendicular diameters of tumor were<br />

measured using a caliper twice a week, and tumor size<br />

was recorded as tumor area (mm 2 ).<br />

Assessment of T cell proliferation<br />

Control and differently treated mice were killed<br />

20 days after tumor implantation, and spleens were<br />

harvested. T cells were isolated from splenocytes by<br />

the use of T cell separation reagents (Miltenyi Biotec,<br />

Auburn, CA, USA). Purified T cells (1 × 10 5 /well)<br />

were co-cultured with Renca tumor lysate-pulsed<br />

dendritic cells (1 × 10 4 /well) in 96-well plates. On day<br />

five, cultures were pulsed with 1 μCi [3H]thymidine<br />

(PerkinElmer, Waltham, MA, USA) per well for 16<br />

hours. The cells were collected on glass microfiber<br />

filters with a cell harvester. T cell proliferation was<br />

evaluated by measuring [3H]thymidine incorporation<br />

in a liquid scintillation counter. Results were expressed<br />

as counts per minute (cpm).<br />

Cytotoxicity assay<br />

A standard 51 Cr release assay was used to measure<br />

cell-mediated cytotoxicity [19] . In brief, Renca tumor cells<br />

were used as target cells. Target cells were labeled with<br />

51<br />

Cr (PerkinElmer, Waltham, MA, USA) for one hour<br />

at 37 °C and washed three times before use. Spleens<br />

were harvested from control and differently treated<br />

mice 20 days after tumor implantation. CD8 + T cells<br />

were isolated from splenocytes by the use of CD8 + T<br />

cell separation reagents (Miltenyi Biotec, Auburn, CA,<br />

USA), and stimulated in vitro with Renca tumor lysatepulsed<br />

dendritic cells at a 10:1 ratio. After five days,<br />

the primed CD8 + T cells (effector cells) were harvested,<br />

washed twice, and co-incubated with 51 Cr-labeled<br />

Renca tumor cells (target cells) at effector / target cell<br />

ratio of 100:1 in round-bottom 96-well plates. After<br />

four hours of incubation at 37 °C, culture supernatants<br />

were collected and 51 Cr release was measured using a<br />

gamma counter. The percentage of target cell specific<br />

lysis was calculated using the following formula:<br />

[(experimental 51 Cr release - spontaneous 51 Cr release)<br />

/ (maximal 51 Cr release - spontaneous 51 Cr release)] ×<br />

100 [20] . Spontaneous release of 51 Cr was determined by<br />

incubating target cells alone. Maximal 51 Cr release was<br />

obtained by incubating target cells with 1% Triton X-<br />

100 (Sigma-Aldrich, St. Louis, MO, USA).<br />

Measurement of interferon-γ production<br />

Twenty days after tumor implantation, spleens from<br />

control and differently treated mice were harvested.<br />

CD4 + T cells were isolated from splenocytes by the use<br />

of CD4 + T cell separation reagents (Miltenyi Biotec,<br />

Auburn, CA, USA), and stimulated with Renca tumor<br />

lysate-pulsed dendritic cells at a ratio of 10:1 in vitro.<br />

After 24 hours, culture supernatants were collected and<br />

determined for interferon-γ content by enzyme-linked<br />

immunosorbent assay (ELISA) kit (BD PharMingen,<br />

San Diego, CA, USA).<br />

Statistical analysis<br />

The data were presented as mean ± standard<br />

deviation (SD). Two-tailed Student’s t-test was used<br />

for data analysis. A p-value of less than 0.05 was<br />

considered statistically significant. GraphPad Prism<br />

software (GraphPad Software Inc, San Diego, CA,<br />

USA) was used for all statistical analysis.<br />

Fig. 1: Phenotype of dendritic cells. The dendritic cells were cultured as described in the methods. Immature and mature dendritic cells<br />

were harvested, stained with fluorescein isothiocyanate-labeled anti-CD11c (dendritic cell marker) monoclonal antibody and phycoerythrinlabeled<br />

anti-CD83 (maturation marker of dendritic cells) monoclonal antibody, and then analyzed by flow cytometry. Expression rates of<br />

CD11c and CD83 in unpulsed dendritic cells (i.e., immature dendritic cells) and Renca tumor lysate-pulsed dendritic cells (i.e., mature<br />

dendritic cells) were 85.9% (i.e., 3.6% + 82.3%) and 3.6%, and 87.1% (i.e., 71.5% + 15.6 %) and 71.5%, respectively.<br />

dendritic cells (i.e., mature dendritic cells) expressed<br />

higher level of CD83 (maturation marker of dendritic<br />

cells), compared with unpulsed dendritic cells (i.e.,<br />

immature dendritic cells).<br />

Tumor lysate-pulsed dendritic cells up-regulate<br />

CD137 expression on T cells<br />

CD137 expression on T cells was measured before<br />

and after stimulation of T cells with Renca tumor<br />

lysate-pulsed dendritic cells. As shown in Fig. 2,<br />

unstimulated T cells showed low expression of CD137.<br />

At three days after stimulation with Renca tumor<br />

lysate-pulsed dendritic cells, T cells increased the<br />

expression of CD137.<br />

Anti-CD137 antibody potentiates the anti-tumor<br />

efficacy of tumor lysate-pulsed dendritic cells<br />

We tested the anticancer effect of tumor lysatepulsed<br />

dendritic cells and anti-CD137 antibody, alone<br />

or in combination, in the subcutaneous Renca tumor<br />

mouse model. As shown in Fig. 3, tumor lysate-pulsed<br />

dendritic cells or anti-CD137 antibody treatment<br />

significantly suppressed tumor growth compared<br />

with control (untreated) group (p < 0.05). However,<br />

the combination therapy with tumor lysate-pulsed<br />

dendritic cells and anti-CD137 antibody resulted in<br />

the greatest inhibition of tumor growth (p < 0.05),<br />

indicating a synergistic anticancer effect of the<br />

combined treatment.<br />

Combination of tumor lysate-pulsed dendritic<br />

cells with anti-CD137 antibody augments T-cell<br />

proliferation<br />

T cells isolated from splenocytes of control<br />

and differently treated mice were assayed for cell<br />

proliferation in response to Renca tumor lysate-pulsed<br />

dendritic cells. As shown in Fig. 4, mice treated with<br />

tumor lysate-pulsed dendritic cells or anti-CD137<br />

antibody alone showed a significant increase in T-cell<br />

proliferation, compared with control group (p < 0.05).<br />

However, co-administration of tumor lysate-pulsed<br />

dendritic cells with anti-CD137 antibody resulted in<br />

stronger cell proliferation than any other groups (p <<br />

0.05).<br />

Combination therapy improves cytotoxic T-<br />

lymphocyte activity<br />

CD8 + T cells isolated from splenocytes of control<br />

and differently treated mice were stimulated in vitro by<br />

co-culture with Renca tumor lysate-pulsed dendritic<br />

cells and analyzed for cytotoxic T-lymphocyte activity.<br />

The cytotoxic T-lymphocyte activity in tumor lysatepulsed<br />

dendritic cells or anti-CD137 antibody-onlytreated<br />

mice was significantly increased in comparison<br />

with control (untreated) mice (p < 0.05) (Fig. 5). The<br />

combination treatment with tumor lysate-pulsed<br />

dendritic cells and anti-CD137 antibody caused a<br />

much higher cytotoxic T-lymphocyte activity than<br />

either monotherapy (p < 0.05) (Fig. 5).

DISCUSSION<br />

Dendritic cells, the most potent antigen-presenting<br />

cells, have the ability to process and present tumor<br />

antigen to both CD4 + and CD8 + T cells [21] . The<br />

interaction between dendritic cells and T cells induces<br />

dendritic cells + anti-CD137 antibody-treated mice. Renca<br />

tumor-bearing mice (10 per group) were not treated or treated with<br />

tumor lysate-pulsed dendritic cells, anti-CD137 antibody, or tumor<br />

lysate-pulsed dendritic cells plus anti-CD137 antibody. CD8 + T cells<br />

(effector cells) isolated from splenocytes of untreated and differently<br />

treated mice were stimulated in vitro with Renca tumor lysatepulsed<br />

dendritic cells for five days, and reacted with 51 Cr-labeled<br />

Renca tumor cells (target cells) at effector/target cell ratio of 100 : 1<br />

for 4 hours at 37°C. Cytotoxic T-lymphocyte activity against Renca<br />

tumor cells was measured by a standard 51 Cr release assay. Results<br />

were expressed as the percentage of target cell lysis. *p < 0.05 versus<br />

proliferation and activation of T cells [11] . Activated<br />

CD8 + T cells become cytotoxic T lymphocyte with<br />

the ability to kill tumor cells [22] . Activated CD4 + T<br />

cells have been shown to provide help for CD8 + T cell<br />

activation by releasing cytokines, such as interferon-γ<br />

and interleukin-2 [23] . Dendritic cell-based vaccines have<br />

been applied clinically for the treatment of metastatic<br />

renal cell carcinoma [12, 24] . However, a number of clinical<br />

studies have displayed limited success [12, 24] . The<br />

CD137 is expressed predominantly on activated CD4 +<br />

and CD8 + T cells [15] . Ligation of CD137 by anti-CD137<br />

monoclonal antibody increases T-cell proliferation<br />

and activation [16] , and prevents activation-induced<br />

death of T cells [25] . It has been reported that treatment<br />

with anti-CD137 antibody leads to regression of wellestablished<br />

tumors in animal models [17, 26] . On the<br />

basis of the reason as mentioned in the introduction,<br />

we postulated that anti-CD137 antibody may enhance<br />

the anti-tumor effect induced by dendritic cell-based<br />

vaccine. Our study showed that T cells up-regulated<br />

CD137 expression after stimulation by tumor lysatepulsed<br />

dendritic cells (i.e., dendritic cell-based<br />

vaccine) (Fig. 2). The result provided scientific basis<br />

for subsequent application of anti-CD137 antibody.<br />

In the present study, we found that combination<br />

therapy with tumor lysate-pulsed dendritic cells and


<strong>December</strong> <strong>2012</strong><br />

KUWAIT MEDICAL JOURNAL 314<br />

anti-CD137 antibody significantly inhibited tumor<br />

growth, compared with a single treatment with tumor<br />

lysate-pulsed dendritic cells or anti-CD137 antibody<br />

(Fig. 3). These data suggest that anti-CD137 antibody<br />

administration improves anti-tumor efficacy of tumor<br />

lysate-pulsed dendritic cells. In addition, we have not<br />

observed apparent side effects in mice treated with<br />

tumor lysate-pulsed dendritic cells and anti-CD137<br />

antibody. The result suggests that combination therapy<br />

is safe.<br />

The anti-tumor immune responses can be<br />

monitored by T-cell proliferation assay, cytotoxicity<br />

test, and cytokine secretion assay [13] . In the present<br />

study, mice immunized with tumor lysate-pulsed<br />

dendritic cells plus anti-CD137 antibody showed<br />

a stronger T-cell proliferation compared with mice<br />

immunized with tumor lysate-pulsed dendritic cells<br />

or anti-CD137 antibody alone (Fig. 4). These findings<br />

indicate that combination treatment promotes T-<br />

cell proliferation. Moreover, cytotoxic T-lymphocyte<br />

activity was higher in mice receiving combination<br />

treatment than in mice treated with tumor lysatepulsed<br />

dendritic cells or anti-CD137 antibody alone<br />

(Fig. 5), suggesting that combination therapy increases<br />

CD8 + T cell activity to kill tumor cells. In cytokine<br />

secretion assay, significantly higher interferon-γ levels<br />

were observed in mice that received combination<br />

therapy than those treated with tumor lysate-pulsed<br />

dendritic cells or anti-CD137 antibody alone (Fig. 6),<br />

implying that combination therapy enhances CD4 + T<br />

cell activity to secrete interferon-γ. The interferon-γ has<br />

been demonstrated to activate CD8 + T cells [23] . After<br />

considering all these results, we think that combination<br />

therapy may augment anti-tumor effect by enhancing<br />

T-cell proliferation and activity.<br />

Tumor cells are known to secrete transforming<br />

growth factor-β (TGF-β), vascular endothelial growth<br />

factor (VEGF), and interleukin-10 (IL-10) [18] . These<br />

tumor-related cytokines can suppress maturation of<br />

dendritic cells in vivo, leading to impaired antigen<br />

presentation and T-cell stimulation, and finally failure<br />

to induce a full anti-tumor immune responses [18, 27, 28] .<br />

As a result, we used in vitro cultured dendritic cells in<br />

the present study. The immature dendritic cells can be<br />

produced in vitro by differentiation of bone marrow<br />

cells by addition of granulocyte macrophage colonystimulating<br />

factor and interleukin-4 for six days [18] .<br />

They can be further differentiated into mature dendritic<br />

cells by addition of maturation stimuli such as tumor<br />

lysate, tumor necrosis factor-α, and interferon-γ [18,29] .<br />

In our study, cultured cells were characterized as<br />

dendritic cells based on high expression of CD11c,<br />

which is a typical dendritic cell marker (Fig. 1). In<br />

clinical trials, immature or mature dendritic cells have<br />

been used for the treatment of renal cell carcinoma [12] .<br />

Recent clinical studies have showed that the use of<br />

mature dendritic cells can generate a better antitumor<br />

efficacy [12] . Thus, we used mature dendritic<br />

cells (i.e., Renca tumor lysate-pulsed dendritic cells)<br />

in our experiment. The mature dendritic cells were<br />

characterized by high expression of CD83 (maturation<br />

marker of dendritic cells) (Fig. 1).<br />

Dendritic cells pulsed with tumor antigens, such<br />

as tumor lysate, defined tumor-associated peptides,<br />

apoptotic or necrotic tumor cells, and tumor RNA<br />

or DNA, are able to induce specific T-cell responses<br />

against tumor cells [30] . The most commonly used tumor<br />

antigen in the clinical studies is tumor lysate [12] . We also<br />

used tumor lysate as tumor antigen in our study. The<br />

use of tumor lysate has unique advantages. It provides<br />

entire repertoire of tumor-associated antigens, thereby<br />

decreasing possibility of tumor escape. In addition,<br />

it also removes the requirement to identify tumorassociated<br />

antigens.<br />

We found that CD137 expression on T cells<br />

reached a peak three days after stimulation of T<br />

cells with tumor lysate-pulsed dendritic cells (Fig.<br />

2B). For this reason, in combination therapy group,<br />

we injected anti-CD137 antibody three days after<br />

treatment with tumor lysate-pulsed dendritic cells.<br />

Some studies have shown that anti-CD137 antibody<br />

at a dose of 100 μg is effective in treating tumors in<br />

mice, such as breast cancer, melanoma, mastocytoma<br />

and myeloma [31, 32] . Consequently, we chose this dose<br />

in renal cell carcinoma mouse model.<br />

CONCLUSION<br />

Our findings present the first evidence that<br />

dendritic cell-based vaccine in combination with anti-<br />

CD137 antibody can enhance anti-tumor effect in<br />

mice bearing renal cell carcinoma by increasing T-cell<br />

proliferation and activity. We propose that combination<br />

therapy may have the clinical applicability in patients<br />

with renal cell carcinoma. Additional clinical trials will<br />

be required to address this issue.<br />

ABSTRACT<br />

Objective: Scrotal varicocele is found to be associated with<br />

increased spermatozoal reactive oxygen species (ROS)<br />

production and decreased seminal plasma antioxidant<br />

activity. Our objective was to search for an association<br />

between male infertility and gene polymorphisms (PON1,<br />

ENOS G894T and Catalase -262C→T).<br />

Design: Controlled prospective study<br />

Setting: Ataturk and Yuksek Ihtisas Education and Training<br />

Hospitals, Ankara, Turkey<br />

Subjects: Forty primary infertile men and forty healthy men<br />

were included in the study. Patients with clinical varicocele<br />

in the study group had no endocrinopathy, no surgery for<br />

varicocele / inguinal hernia, and / or no leukospermia. They<br />

were non-smokers.<br />

Intervention: Doppler ultrasonography (USG) was<br />

performed for the patients. For genetic analysis, 5 ml of<br />

venous blood was drawn into tubes containing EDTA from<br />

each patient.<br />

Main Outcome Measures: Gene polymorphism, progressive<br />

sperm motion and vein diameter<br />

Results: Existence of gene polymorphisms was statistically<br />

important in patients who had clinical varicocele with affected<br />

progressive forward motion. We determined statistically<br />

significant rate of gene polymorphisms in enzymatic<br />

antioxidant defence systems in patients with clinical varicocele,<br />

with a diameter of spermatic vein above 2.2 mm and forward<br />

progressive sperm motion below 32% (p < 0.001).<br />

Conclusions: These polymorphisms might represent risk<br />

factors for Turkish men with clinical varicocele and forward<br />

progressive sperm motion defect. This is a pilot study. We<br />

intend to continue these studies with larger sample sizes to<br />

confirm these findings.<br />

Key words: gene polymorphism, male infertility, oxidative stress, varicocele<br />

INTRODUCTION<br />

Varicocele is an abnormal dilatation of the<br />

spermatic vein, and it is observed in around 30 - 50%<br />

of men in infertile couples [1] . A considerable number<br />

of infertile men have no known mechanism for their<br />

infertility [2] . Several mechanisms which involve the<br />

pathophysiology of testicular dysfunction in the<br />

population with varicocele have been defined. The<br />

other pathophysiological mechanisms of varicocele are<br />

Leydig cell and germinal cell dysfunction due to small<br />

vessel occlusion, testicular hypoxia due to venous stasis,<br />

retrograde flow of adrenal and renal metabolites from<br />

the renal vein into the spermatic vein, increased scrotal<br />

and testicular temperature and decreased secretion of<br />

gonadotropins and androgens [3] . In addition to these,<br />

varicocele also reduces both the seminal and blood<br />

plasma antioxidant defenses [4] . Scrotal varicocele is<br />

found to be associated with increased spermatozoal<br />

reactive oxygen species (ROS) production and<br />

decreased seminal plasma antioxidant activity [5] . Excess<br />

ROS leads to DNA damage and oxidation of lipoprotein<br />

components at the cellular and subcellular level.<br />

Oxidative stress (OS) adversely affects sperm function<br />

by changing membrane fluidity and permeability, and<br />

The Effect of Gene Polymorphisms (ENOS G894T, PON1 and Catalase -262C→T) ...<br />

<strong>December</strong> <strong>2012</strong><br />

impairs sperm functional competence [6] . We searched<br />

for an association between polymorphisms of different<br />

plasma enzymatic antioxidants (PON1, ENOS G894T<br />

and Catalase -262C→T gene polymorphisms) in a<br />

Turkish male population with fertility and varicocele,<br />

based on the impairment of spermatozoa functions<br />

related with increased ROS. This study also aims to<br />

examine, if there is an association between different<br />

plasma enzymatic antioxidants (PON1, ENOS G894T<br />

and Catalase -262C→T gene polymorphisms) and<br />

idiopathic male infertility.<br />

SUBJECTS AND METHODS<br />

Population of the Study<br />

Forty male patients with primary infertility with a<br />

mean age of 36.8 ± 6.91 years and forty healthy men<br />

with a mean age of 41.2 ± 7.63 years were included<br />

in the study. The patients were included in the study<br />

after physical examination by an urologist. Patients,<br />

in whom left-sided grade 2 varicocele was detected,<br />

were evaluated radiologically with scrotal coloured<br />

doppler ultrasonography (USG). After evaluation<br />

with scrotal doppler [7] , patients with clinical varicocele<br />

who had varicose vein with reflux and diameter above<br />

2.2 mm were included in the study group. Patients<br />

were included in the study after 3 - 5 days of sexual<br />

abstinence. Two different laboratory examinations<br />

were performed, at least 15 days apart, and the<br />

sperm parameters were evaluated according to WHO<br />

guidelines [8] . Fertile men were included in the study as<br />

control group. The patients had sperm profiles with a<br />

count of 5 - 55 million/ml, a viscosity with a volume of<br />

2 – 5 ml, normal pH values, and no leukospermia. The<br />

motility was classified as motile a (rapid progressive<br />

motion), motile b (slow progressive motion), motile c<br />

(non-progressive motion), motile d (non-motile sperm<br />

percentiles), motile a + b (32%; progressive sperm<br />

motion) and motile a + b + c (40%; total motion) [8] . The<br />

patients with clinical left-sided varicocele in study<br />

group had no endocrinopathy, no previous surgery<br />

for varicocele or inguinal hernia and no leukospermia.<br />

They were also non-smokers. The study group<br />

consisted of patients who had no child despite regular<br />

sexual intercourse for at least a year. Fertile men were<br />

included in the control group. Informed consent forms,<br />

compatible with the Helsinki declaration, were taken<br />

from the patients and the Institutional Review Board<br />

approved the study.<br />

Genotyping For eNOS G894T Polymorphism<br />

For genetic analysis, 5 ml of blood was drawn into<br />

tubes containing EDTA from each patient. DNA was<br />

extracted using a commercial kit (QIAamp DNA mini<br />

kit; Qiagen, Hilden, Germany). In this study, for the<br />

detection of G894T polymorphism on ENOS gene, we<br />

used primer pairs to amplify a part of the ENOS gene<br />

containing exon 7, by polymerase chain reaction (PCR)<br />

with the following flanking intronic primers: sense<br />

5’CATGAGGCTCAGCCCCAGAAC-3’ and antisense<br />

5’AGTCAATCCCTTTGGTGCTCAC-3’, followed by<br />

Mbo I restriction endonuclease digestion for 16h at 37 °C<br />

and resolution by electrophoresis on 3% agarose gel.<br />

The resulting 206 bp PCR product was cleaved into<br />

two smaller fragments of 119 and 87 bp in the presence<br />

of a T nucleotide at 894 (corresponding to Asp 298) but<br />

not in its absence. Digested fragments were visualized<br />

after ethidium bromide staining under UV light.<br />

Genotyping For Paraoxonase 192 Polymorphism<br />

PON1 genotypes were determined by PCR<br />

according to previously published protocols [9,10] .<br />

For paraoxonase 192 polymorphism, a sense primer<br />

5’TATTGTTGCTGTGGGACCTGAG3’ and antisense<br />

primer 5’ CACGCTAAACCCAAATACATCTC 3’,<br />

which encompasse the 192 polymorphic region of<br />

the human PON1 gene, were used. The PCR reaction<br />

mixture contained 100 ng DNA template, 0.5 M of<br />

each primer, 1.5 mM MgCl2, 200 mM dNTPs and<br />

1 U Taq DNA polymerase (MBI Fermentas). After<br />

denaturing the DNA for 5 min at 94 °C, the reaction<br />

mixture was subjected to 35 cycles of denaturation<br />

for one min at 95 °C, one min annealing at 60 °C and<br />

one min extension at 72 °C, for the 192 genotype.<br />

The 99 bp PCR product was digested with 8U BspI<br />

restriction endonuclease (MBI Fermentas, Lithuania)<br />

overnight at 55 °C, the digested products separated<br />

by electrophoresis on a 4% metaphore agarose gel and<br />

visualized using ethidium bromide. The B-genotype<br />

(arginine) contains a unique BspI restriction site which<br />

results in 66- and 33-bp products and the A genotype<br />

(glutamine) cannot be cut, allowing the PON1 192<br />

genotype to be determined.<br />

Genotyping for catalase - 262C→T polymorphism<br />

Genotyping for the CAT - 262C→T polymorphism<br />

was conducted according to the method described<br />

by Forsberg et al with modifications [11] . PCR<br />

amplification of the associated region of the CAT<br />

gene promotor site was performed using the primers<br />

5’-AGAGCCTCGCCCCGCCGGACCG-3’ (antisense)<br />

and 5’-TAAGAGCTGAGAAAGCATAGCT -3’ (sense)<br />

with a touch-down program designed as follows: 94°C<br />

for 30 s, 68 °C for 45 s, 72 °C for one min, -0.5 °C/cycle,<br />

19 times, then 94 °C for 30 s, 58 °C for 45 s, 72°C for<br />

one min, 25 times. The final elongation step was 10<br />

min at 72 °C. Each reaction mixture (25 ml) contained<br />

approximately 50 ng of DNA template, five units of<br />

Taq DNA polymerase, 1 mM of each primer, 200 mM<br />

dNTPs, 20 mM Tris–HCl (pH 8.4), 50 mM KCl and 1.5<br />

mM MgCl2. For restriction digestion with SmaI, 15 ml<br />

were withdrawn from the amplification mixture and<br />

incubated with five units of the enzyme in the presence

of spermatic vein between the infertile and fertile<br />

groups included in the study (p < 0.05, Table 1). The<br />

rates of sperm motility in the patients were 16.32<br />

± 7.99% at a motile sperm, 25.65 ± 6.21% at b motile<br />

sperm, 41.97 ± 10.88% at a + b motile sperm, 17.12 ±<br />

9.21% at c motile sperm and 41.40 ± 12.48% at d motile<br />

sperm. The diameter of scrotal doppler varicose vein<br />

for the patients in study group was 2.81 ± 0.39 mm, it<br />

was 2.1 ± 0.60 mm in the control group (Table 1). The<br />

incidence of PON1, ENOS G894T and Catalase -262C→<br />

T gene polymorphisms were studied in peripheral<br />

blood from all the study participants. PON1 gene<br />

polymorphism was detected in 27 of 80 participants<br />

(33.7%). 16 of them were infertile, 11 of them were<br />

fertile. ENOS gene polymorphism was detected in 32<br />

participants (40%) (17 infertile and 15 fertile). Catalase<br />

- 262C → T gene polymorphism was detected in 35<br />

participants (43.7%). 19 of them were infertile and 16<br />

were fertile (Table 2). The study group consisted of<br />

40 infertile patients with varicocele and the control<br />

group consisted 40 fertile patients. All of the study<br />

group patients had varicocele, but only 12 patients in<br />

control group had varicocele. The distribution of gene<br />

polymorphism in infertile and fertile participants with<br />

varicocele is shown in Table 3. There was no statistically<br />

significant difference in terms of gene polymorphism<br />

(PON1, ENOS G894T and Catalase - 262C → T gene<br />

polymorphisms) between the infertile and fertile<br />

groups (p > 0.05, p-value was 0.648, 0.237 and 0.499<br />

respectively) (Table 4). Similarly, total sperm motion<br />

in all the patients between above 40% and below<br />

40% were compared and no statistically significant<br />

difference was found in terms of gene polymorphisms<br />

(p-value was 0.920, 0.901 and 0.641 respectively)<br />

(Table 5). But, when progressive sperm motion with a<br />

motility above 32% and below 32% were compared in<br />

all of the patients, there was a statistically significant<br />

difference in terms of the three gene polymorphisms<br />

(p-value was 0.001, 0.001 and 0.020 respectively)(Table<br />

5). Spermatic vein diameters of all of the patients<br />

were classified and evaluated. According to this<br />

evaluation, when spermatic vein diameters above 2.20<br />

mm and below 2.20 mm were compared, there was a<br />

statistically significant difference in terms of the gene<br />

polymorphisms (p-value was 0.001, 0.001 and 0.003,<br />

respectively) (Table 5).<br />

DISCUSSION<br />

Oxidative stress results from an imbalance between<br />

production and removal of ROS, leading to both a<br />

steady state concentration of reactive intermediates<br />

higher than normal and to increased cellular<br />

damage. Several studies have shown that there is a<br />

correlation between oxidative stress and impaired<br />

sperm function [12-15] . Although ROS play important<br />

roles in the promotion of spermatozoa capacitation,<br />

hyperactivation, and fusion [16-19] , they must be<br />

controlled to avoid harmful effects [20] . To accomplish<br />

this control, seminal plasma possesses an array of<br />

enzymatic and non-enzymatic defense mechanisms.<br />

Increased ROS generation was reported in 40% of<br />

the general infertile population, compared to 80% in<br />

the infertile varicocele population [21-25] . Despite these<br />

results in the literature, in our study, we determined<br />

that antioxidant gene polymorphisms are associated<br />

with varicose vein diameter and forward progressive<br />

sperm motion rather than fertility (Table 4 and 5). A<br />

relationship has also been detected between oxidative<br />

stress, semen characteristics and clinical diagnosis in<br />

investigated infertile patients. It is reported that the<br />

total antioxidant levels in patients with idiopathic<br />

infertility, varicocele, vasectomy reversal and infection<br />

with varicocele were significantly less than those in<br />

the fertile control group [26] . The association between<br />

varicocele and infertility is well-known. Frequently,<br />

men with varicocele have an abnormal spermiogram<br />

that usually improves after repair [27,28] . ROS production<br />

is usually high in those with a varicocele and improves<br />

after varicocelectomy [26,29] . In addition, exposure to<br />

cigarette smoke, a source of free radicals, contributes<br />

to a deterioration of the spermiogram in patients with<br />

a varicocele [30] . The total antioxidant capacity might<br />

also contribute strongly to the pathophysiology of<br />

male infertility, irrespective of the clinical diagnosis.<br />

Many findings support that male infertility associated<br />

with scrotal varicocele is at least in part related to<br />

oxidative stress. Varicocele patients were detected to<br />

have decreased antioxidant defenses both at the local<br />

(seminal plasma) and systemic (blood plasma) levels [21] .<br />

Barbieri et al measured the total antioxidant potential<br />

defenses, not individually, of varicocele patients in both<br />

seminal plasma and in systemic circulation. They report<br />

that the antioxidant defenses decrease in both of them.<br />

They conclude that varicocele-associated oxidative<br />

stress is evident not only at the local site but also at the<br />

systemic levels [21] . According to Ichioka et al, individual<br />

susceptibility to varicocele-induced ROS may depend<br />

on one or more of these genetic polymorphisms and<br />

that the outcome of varicocelectomy may be influenced<br />

by an individual’s genetic susceptibility to ROS [31] .<br />

In our study, there was no statistically significant<br />

difference for gene polymorphisms between study<br />

and control group (Table 4), but it was significant in<br />

patients with varicocele who had a vein diameter of<br />

above 2.2 mm and forward progressive sperm motion<br />

below 32% (Table 5). Increased ROS production can<br />

deplete the defenses present in the testes and in<br />

seminal plasma. For example, it has been reported<br />

that total reactive antioxidant potential (TRAP) in the<br />

internal spermatic vein (measured during surgery)<br />

is significantly lower than in a peripheral vein [32] .<br />

Varicocele reduces both the seminal and blood<br />

plasma antioxidant defenses. In order to further<br />

stress the relationship between local and systemic<br />

defenses depletion, average values are plotted for the<br />

different groups. One study shows that there is a good<br />

correlation between both sets of values. This is the<br />

first instance in which it is established that a systemic<br />

decrease in antioxidant defenses is present in those<br />

with a varicocele [33] . It is difficult to determine if the<br />

systemic decrease is reflected in the seminal levels or<br />

in systemic circulation [33,34] . Increased reactive oxygen<br />

radicals in systematic circulation cause negative<br />

effects on sperm function. This implies that significant<br />

KUWAIT MEDICAL JOURNAL 320<br />

antioxidant consumption at the testis level can be<br />

related to the increased ROS production [21] . The results<br />

discussed above suggest that antioxidant defenses<br />

could be depleted both locally and systemically in<br />

varicocele patients. In particular, it was considered<br />

important to establish if oxidative stress indicators<br />

are modified and non-enzymatic antioxidants are<br />

depleted in seminal and blood plasma of varicocele<br />

patients [32] . In our study, we used peripheral blood<br />

both in the study group (infertile patients) and the<br />

control group (fertile group), because using the<br />

specimen from the varicose vein of the control group<br />

was an ethical concern. We determined statistically<br />

significant rate of gene polymorphism in enzymatic<br />

antioxidant defence systems in patients with clinical<br />

varicocele, with a diameter of spermatic vein above 2.2<br />

mm and forward progressive sperm motion below 32%.<br />

But, we could not determine any significant difference<br />

in terms of gene polymorphisms in our infertile study<br />

group compared to fertile control group. There was<br />

also no statistically significant difference in patients<br />

with total sperm motion (below and above 40%). This<br />

is a controlled prospective study and it is also the<br />

first study which searches the association between<br />

infertility and gene polymorphism of enzymatic<br />

antioxidant defense system. Although our patient and<br />

control group is small, this is the first pilot study which<br />

includes patients with fertility and infertility, their<br />

sperm features (progressive and total sperm motion)<br />

and spermatic vein diameter (with and without<br />

varicocele) in literature. We want to continue the study<br />

with larger groups in future. Perhaps then, we will<br />

also find a relationship between infertility and gene<br />

polymorphism as the number of the patients increase.<br />

CONCLUSION<br />

Antioxidant gene polymorphisms can be detected<br />

in fertile and infertile men with varicocele. It would be<br />

important to investigate whether these polymorphisms<br />

can take place in fertile and / or infertile men with<br />

varicocele. These polymorphisms might represent<br />

a risk factor for Turkish men with clinical varicocele<br />

and forward progressive sperm motion. This is a pilot<br />

study. We intend to continue these studies with a larger<br />

sample size to confirm these findings.<br />

ABSTRACT<br />

Kuwait Medical Journal <strong>2012</strong>; <strong>44</strong> (4): 322 - 325<br />

Objective: To look at the characteristics and mortality of<br />

mechanically ventilated patients on a general medical ward.<br />

The purpose of this audit is to evaluate this practice and<br />

also help clarify the need for “do not resuscitate” orders in<br />

Kuwait.<br />

Design: Prospective, observational audit<br />

Setting: Mubarak Al-Kabeer Hospital, Ministry of Health,<br />

Kuwait<br />

Subjects: Mechanically ventilated patients on medical wards<br />

in Mubarak Al-Kabeer Hospital over a six-month period<br />

Intervention: Mechanical ventilation<br />

Main Outcome Measures: Primary outcome was death and<br />

secondary outcome was extubation<br />

Results: Eighty-one patients met the inclusion criteria. Most<br />

patients had over three medical problems with a high number<br />

of patients having brain dysfunction, cancer and end-stage<br />

diseases. The mortality rate was 95%.<br />

Conclusion: There is great need to further look into this<br />

practice which appears to be highly fatal. There is evidence<br />

for the need to introduce a “do not resuscitate” policy in<br />

Kuwait, which is an ethical necessity in the practice of<br />

medicine.<br />

KEY WORDS: mechanical ventilation, medical ward, resuscitation<br />

INTRODUCTION<br />

Ever since the creation of the first positive pressure<br />

mechanical ventilator in the 19 th century there has been<br />

a constant demand for it in hospitals around the world.<br />

The number of patients requiring such devices has also<br />

grown exponentially since that time. The outcome of<br />

patients on mechanical ventilation even in specialized<br />

centers, like the Intensive Care Unit (ICU) has been<br />

inconsistent due to a variety of causes [1] .<br />

Due to limited resources and the increasing demand<br />

for ICU beds with no “do not resuscitate (DNR)” policy,<br />

for the past 10 years in Kuwait, we have selectively<br />

placed some patients on mechanical ventilators in<br />

the general medical wards. Most of these patients<br />

are usually those on medical grounds “should not<br />

have been resuscitated or intubated” due to predicted<br />

poor prognosis. The aim of this audit was to look at<br />

the mortality of these patients who are mechanically<br />

ventilated in the medical wards in Mubarak Al-Kabeer<br />

Hospital, Kuwait (MKH).<br />

MKH is a secondary referral hospital servicing<br />

approximately one third of the population of Kuwait<br />

(1 million inhabitants). It has a total of 450 beds of<br />

which 186 are allocated to adult medical patients. To<br />

the best of our knowledge, there are very few countries<br />

in the world that do not have a DNR policy and<br />

selectively place poor prognosis patients on invasive<br />

mechanical ventilation in the general medical ward.<br />

This is the first time in Kuwait that the mortality and<br />

characteristics of such patients has been reviewed<br />

systematically.<br />

SUBJECTS AND METHODS<br />

We collected data from the general medical wards<br />

in MKH over a six-month period starting from 1 st May<br />

to 31 st October, 2010. The need for written consent<br />

and ethical approval was waived by the local hospital<br />

administration due to the observational nature of the<br />

study. Mechanical ventilation (MV) was either through<br />

a tracheostomy or an endotracheal tube.<br />

We included all patients that were placed on<br />

mechanical ventilation in the medical wards that<br />

survived at least two hours from onset of MV. Since all<br />

patients unselectively receive CPR and are intubated<br />

during the process, we chose two hours as the minimal<br />

survival time post MV. This is to ensure that we are<br />

measuring the mortality of patients on MV in the ward<br />

rather than the mortality of cardiac arrest patients<br />

in the hospital, who are usually intubated during<br />

resuscitation.<br />

323<br />

Ward Mechanical Ventilation (WMV) Audit<br />

<strong>December</strong> <strong>2012</strong><br />

The following exclusion criteria were used:<br />

1. Patient on home mechanical ventilator admitted to<br />

hospital<br />

2. Patients on MV in the ward prior to 1 st May 2010<br />

3. Patients transferred to ICU or CCU (coronary care<br />

unit) within 48 hours<br />

The decision to transfer a patient to the ICU or<br />

keep him in the ward was made by the ICU doctors<br />

on call for that evening, and was based on the patient's<br />

previous medical history and the perceived benefit<br />

from MV, resuscitation or further ICU management.<br />

By visiting the wards every 48 hours and reviewing<br />

the patient’s charts, we collected data about the age,<br />

reason for MV and admission, number of days on<br />

MV and number of days to onset of MV, past medical<br />

history, and location of patients. The reason for<br />

admission was recorded as per the admission sheet.<br />

The reason for MV was recorded as the reason written<br />

at the time of intubation. If the reason for MV was<br />

changed to a more specific one during follow-up, the<br />

reason for MV was changed accordingly. The primary<br />

outcome was death. The secondary outcome was<br />

extubation, which was defined as being disconnected<br />

from mechanical ventilation for a two-week period. If<br />

the patient was reconnected to a ventilator during the<br />

course of the same admission, the period of mechanical<br />

ventilation was considered as one prolonged period.<br />

Unfortunately the final cause of death was not recorded<br />

due to great uncertainty in the cause of death in<br />

many of these patients as well as lack of post-mortem<br />

examination. Therefore, this data was not collected.<br />

The investigators had no input regarding any aspect<br />

of management of the patients.<br />

RESULTS<br />

Over the six-month period, 81 patients were placed<br />

on MV in the ward that met the inclusion criteria.<br />

Complete data were collected for all patients. The<br />

background medical history was grouped into related<br />

diseases for ease of collection and to compare patient’s<br />

characteristics.<br />

Out of the 81 patients that were reviewed, only<br />

four had met the survival criteria achieving an overall<br />

survival of 5% and a mortality of 95% for patients on<br />

MV in the medical ward. Two of the survivors died<br />

during the course of the same admission. Twenty-five<br />

patients survived less than 48 hours (31% of patients),<br />

and 56 survived over 48 hours (69%).<br />

The patients were almost equally divided between<br />

the medical wards. The ratio of male to female patients<br />

was 1:1 (40 patients). The average age of patients was<br />

70.9 years with over 80% of patients being over 60<br />

years (age range 15 – 92 years). The mean number<br />

of medical co-morbidities between male and female<br />

patients was four (mode 5, median 4). 61% of patients<br />

had four or more medical conditions (Fig. 1). All the<br />

conditions. This bar chart shows the percentage of patients and<br />

their associated number of diseases. Most patients had four or more<br />

diseases.<br />

survivors had three or less medical conditions. The<br />

commonest diseases were hypertension (68%) and<br />

diabetes (60%), both present in over 60% of patients.<br />

Chronic kidney disease (CKD), ischemic heart disease<br />

(IHD), chronic obstructive pulmonary disease (COPD),<br />

interstial lung disease (ILD), stroke, and cancer were<br />

also found to be present in many of the patients (Fig.<br />

2). The commonest reason for MV was cardiac arrest<br />

followed by decreased level of consciousness and then<br />

desaturation (Table 1).<br />

The mean length of MV was 20 days and the mean<br />

time to onset of MV from admission was 18 days.<br />

There were 61 (75%) patients in cubicles (a four-bed<br />

room with no door and glass windows on either side<br />

that lets the nurses see the patient from the corridor)<br />

and 30 (25%) patients in private rooms.<br />

was estimated at over a quarter of a million Kuwaiti

dinars / year. Average cost of running a mechanical<br />

ventilation bed on the general medical floor was<br />

calculated to be approximately 85 KD / day which<br />

is only 5 KD over the average cost of normal general<br />

medical bed. Also included into the calculation was<br />

the average cost of expected laboratory and imaging<br />

investigations over that period. This is considered to<br />

be a large underestimate, given the fact that cost of<br />

manpower, medication and the cost of redirection and<br />

utilization of other resources for other patients that<br />

need medical beds was not taken into account in this<br />

estimation.<br />

DISCUSSION<br />

There is very little literature that evaluates the<br />

mortality of patients on mechanical ventilation outside<br />

specialized units like the ICU and CCU. This is mainly<br />

due to the rarity of this clinical scenario in the world<br />

and the general consensus that mechanically ventilated<br />

patients need a higher degree of specialized care.<br />

The mortality rate obtained in this audit was<br />

staggering. At first glance, it seems that mechanically<br />

ventilating a patient on the ward is almost a sure death<br />

sentence for the patient, especially when compared<br />

to the mortality of medical patients that received<br />

mechanical ventilation in the ICU (30%, obtained form<br />

the ICU, MKH mortality census for May to October of<br />

the same year). Looking at the number of the medical<br />

conditions the ventilated patients in the ward had, it<br />

was found that over 84% of them had three or more<br />

medical conditions with a high percentage having<br />

brain dysfunction (dementia, mental retardation or<br />

stroke), cancer and end-stage diseases. These figures<br />

raise many questions and concerns. Why is the<br />

mortality rate of these patients so high? Could it be<br />

due to suboptimal quality of care received by these<br />

patients, our very aggressive resuscitation efforts,<br />

lack of a DNR policy or any selection bias by ICU not<br />

admitting patients they thought will not survive.<br />

Through literature search, we found two articles<br />

that examined at similar problems [2,3] . In both studies,<br />

the authors compared the mortality rate of patients<br />

on invasive MV in the ICU and in the general medical<br />

ward. They showed significant difference in mortality<br />

/ survival of ICU to non-ICU ventilated patients in<br />

favor of ventilation in the ICU.<br />

We compared the care that our patients received<br />

to the care received in the study by Lieberman et al [2] .<br />

The patients in the general medical ward in MKH are<br />

generally examined three times per day. Only one time<br />

a day are they seen by the ICU personnel, who are<br />

trained to deal with mechanically ventilated patients<br />

and can adjust the ventilator to meet the patient’s<br />

needs. The rest of the visits, if any, are done by medical<br />

personnel who have limited experience in dealing with<br />

mechanical ventilators. With regard to nursing care,<br />

the nurse assigned to each patient is looking after 3<br />

- 4 other patients at the same time. They have minimal<br />

expertise in dealing with mechanically ventilated<br />

patients. The patients were also placed in different<br />

rooms including private rooms that are isolated<br />

from the nurse’s station. Lieberman and colleagues [2]<br />

reported a mortality of 68% in patients who were<br />

ventilated in the ward. Their patients were seen five to<br />

six times per day including a visit at night by personnel<br />

who were skilled in managing ventilator patients and<br />

the patients were cared for in one room with a nurse<br />

skilled in their management. Therefore, it seems that<br />

care might have contributed to our higher mortality<br />

outcome and although our audit was observational<br />

and not designed specifically to detect difference in<br />

the outcome based on care, it seems unlikely that this<br />

difference in mortality can be explained by quality of<br />

care alone especially when looking at Lieberman [2] ,<br />

and Hersch [3] patient exclusion criteria.<br />

In contrast to our audit, both studies of Lieberman [2] ,<br />

and Hersch [3] excluded DNR patients and those who<br />

are unlikely to survive over six months. On the other<br />

hand, our study sample was almost entirely made up<br />

of patients who on medical grounds, as judged by ICU<br />

doctors, should not have been resuscitated. Examples<br />

are stroke patients, patients with metastatic cancers,<br />

end-stage heart and lung diseases, which contributed<br />

to our much higher mortality rate. Currently in<br />

Kuwait, we have no DNR orders and when these<br />

patients deteriorate, they are resuscitated for purely<br />

medico-legal or religious purposes. This we deem as a<br />

highly unethical practice.<br />

One could also argue that there is obvious selection<br />

bias of leaving patients that were perceived “will do<br />

worst” to the ward, therefore increasing the mortality<br />

rate in the ward, which is true especially because


325<br />

Ward Mechanical Ventilation (WMV) Audit<br />

<strong>December</strong> <strong>2012</strong><br />

the method of selection was not standardized in the<br />

hospital and was left to the discretion of the ICU<br />

doctor. The counter argument to that is, selection was<br />

based on medical judgment of futility and not only on<br />

resource allocation, and therefore, ICU doctors were<br />

correct 95% of the time in selecting patients that were<br />

judged not to benefit from initial resuscitation and<br />

transfer to the ICU.<br />

It is likely that both suboptimal care and aggressive<br />

resuscitation contributed to the high mortality rate<br />

obtained in this audit. The results of this audit cannot<br />

with certainty determine the exact cause of this high<br />

mortality, because our data was very heterogeneous<br />

and will not allow firm conclusions to be made.<br />

However, the data obtained in this audit is a very<br />

strong proof that we are not benefiting these patients by<br />

resuscitating them and leaving them on the ward. On<br />

the contrary, we are simply prolonging the inevitable<br />

and causing the patient a great deal of harm through the<br />

process of ventilation. Also, it results with a negative<br />

psychological impact on the family by allowing them to<br />

see their relatives in this situation while they are being<br />

falsely reassured that their relative will become better.<br />

There are also obvious massive economic implications<br />

associated with this practice.<br />

Through the decades, physicians have come to<br />

recognize their limitations. They look at the quality of<br />

life of patients that have end-stage disease rather than<br />

simply ensuring that patients have a heart beat and<br />

a recordable blood pressure. Around the world, the<br />

laws have adopted these changes, but unfortunately<br />

in Kuwait, we are still lagging behind in this very<br />

crucial matter due to medical, social and especially<br />

religious misconceptions. Religion has been a powerful<br />

driving force influencing enactment of many polices<br />

in Kuwait. Although it is not in our ability to make<br />

recommendations about religious aspects of ‘end<br />

of life’ policies, it would make sense that the role of<br />

religion is to empower doctors to make a decision for<br />

or against DNR and we have found that, contrary to<br />

popular societal beliefs, Islam does indeed support<br />

the practice of DNR [4] . Patients family and doctors<br />

are paying the price, not only through spending our<br />

limited resources, but also by patient's losing faith in<br />

local medical practice. This loss in faith has resulted<br />

in large number of people looking for medical care<br />

outside Kuwait.<br />

CONCLUSION<br />

It is clear from this audit that ventilating a patient<br />

out of the ICU in our hospital is fatal. Although the<br />

exact reasons for this high mortality rate cannot be<br />

determined from our data, there is overwhelming<br />

evidence that we need to update our laws regarding<br />

DNR (medical, legal, and religious cooperation). Lastly,<br />

we need to further study the characteristics of these<br />

patients who end up ventilated on the general medical<br />

ward in order to make the proper recommendations on<br />

how to improve their survival.<br />

Case Report<br />

Unusual Presentation of Duplex Collecting<br />

System: A Case Report<br />

Mukesh Kumar Vijay, Preeti Vijay, Pramod Kumar Sharma<br />

Department of Urology, IPGME & R, 242 AJC Bose Road, Kolkata, West Bengal, India<br />

Kuwait Medical Journal <strong>2012</strong>; <strong>44</strong> (4): 326 - 328<br />

ABSTRACT<br />

Duplex collecting systems (also known as duplicated<br />

collecting systems) can be defined as renal units containing<br />

two pyelo-caliceal systems that are associated with a single<br />

ureter or double ureters. The two ureters empty separately<br />

into the bladder or fuse to form a single ureteral orifice. We<br />

came across a case in which the diagnosis was in dilemma<br />

until actual surgery when it was finally diagnosed as a case<br />

of duplex collecting system.<br />

KEY WORDS: duplicated collecting system, reterograde pyelogram<br />

INTRODUCTION<br />

Complete duplication of ureters occurs in 0.2% of<br />

live births; the chance of occurrence is 12% in firstdegree<br />

relatives of persons with this condition. The<br />

prevalence of partial duplication found on urograms is<br />

0.6% [1] . We encountered such a case that was initially<br />

diagnosed as infection of the upper urinary tract.<br />

However, subsequent investigation diagnosed it as a<br />

case of complex renal cyst. Finally, intra-operatively the<br />

case could be correctly diagnosed as a case of duplex<br />

collecting system.<br />

CASE HISTORY<br />

A 40-year-old patient presented to our outpatient<br />

department with complaints of dull aching<br />

pain occurring in the right flank region since the<br />

last six months. There was no history of hematuria.<br />

On examination the right kidney was palpable. An<br />

ultrasound examination of the patient revealed a<br />

single, irregular shaped cyst of size 104.2 x 66.1 mm<br />

with echogenic fluid in the lumen, in upper cortex<br />

of the right kidney. Intravenous urography showed<br />

the upper and middle calyx of the right kidney to be<br />

displaced in an arc-like fashion, suggestive of a cyst / mass<br />

lesion of the right kidney (Fig. 1). Keeping a provisional<br />

diagnosis of renal cyst in mind the patient was advised<br />

a contrast enhanced CT scan of the abdomen and pelvis<br />

which showed a thick walled, lobulated cystic lesion<br />

with thin peripheral calcification and few internal<br />

septa, measuring 82.5 x 64.77 x 100 mm arising from<br />

the anterior aspect of the right kidney (Fig. 2). The<br />

wall of the cyst and the internal septa were seen to<br />

enhance post- contrast. With the diagnosis of complex<br />

renal cyst (Bosnaick’s type 3) the patient was posted<br />

for partial / radical nephrectomy. A reterograde<br />

pyelogram done during the operation showed upper<br />

calyx of the right kidney to be arc-like, besides a<br />

faintly opacified grossly dilated pelvi-calyceal system<br />

inferior to the arched upper calyx (Fig. 3). It was at<br />

this time that the possibility of a duplex renal system<br />

occurred to us. On exploration the patient was found<br />

to have a duplicated pelvi-calyceal system with<br />

duplex upper ureter (Fig. 4). The lower system had a<br />

very short ureter along with obstruction of the pelviureteric<br />

junction. The lower pelvi- calyceal system<br />

was grossly dilated. However, the upper system was<br />

not dilated. The narrowed pelvi-ureteric junction and<br />

the short lower ureter were excised and the pelvis of<br />

the lower system was anastomosed in an end to side<br />

fashion to the ureter of the upper system. Postoperative<br />

recovery was uneventful and the patient was found<br />

to be progressing well during follow-up.<br />

Differential diagnoses considered in this case<br />

were:<br />

Complex renal cyst (Bosnaick’s type 3)<br />

Infected cyst ( abcess or antibioma)<br />

Duplex kidney with non-functioning lower pole<br />

DISCUSSION<br />

Duplicated collecting systems (also known as<br />

duplex collecting systems) can be defined as renal<br />

units containing two pyelo-caliceal systems that are<br />

associated with a single ureter or double ureters. The<br />

prevalence of partial duplication found is 0.6% [2] .<br />

When a single ureteral bud bifurcates before the<br />

ampulla bifurcates, a duplex kidney with a bifid renal<br />

pelvis or bifid ureter results [1] .<br />

Most patients are asymptomatic, with genitourinary<br />

tract abnormalities being detected incidentally on<br />

imaging studies performed for other reasons. Urinary<br />

tract infection and parenchymal scarring is increased<br />

in patients with a duplex collecting system; patients<br />

can present with pyrexia, pain and dysuria. Ureteropelvic<br />

junction obstruction is more common when a<br />

duplex kidney exists [2] . Giant hydronephrosis in a<br />

duplex kidney can manifest as an extremely large<br />

abdominal and retroperitoneal mass; in rare cases, it<br />

can cause hypertension.<br />

During ultrasonography, the duplex kidney appears<br />

as two central echo complexes with intervening renal<br />

parenchyma. Hydronephrosis at one pole is suggestive<br />

of a duplex kidney [3] . Although hydronephrosis can<br />

occur at either pole, it is more common in the upper<br />

one. The ultrasonographic appearance of a duplex<br />

kidney is specific but not sensitive. Differentiating<br />

an atrophied lower pole moiety of a duplex kidney<br />

(nubbin) from other renal masses is difficult [4] .<br />

With excretory urography, duplex kidney is<br />

usually longer than the non-duplex kidney. Calyces<br />

are asymmetric. Ectopic, upper pole ureteric insertion<br />

can produce a non-opacified segment. This mass effect<br />

results in the “drooping lily” sign with the depression<br />

of the lower pole pelvi-caliceal system. If the lower<br />

pole of the duplex kidney is functioning poorly or<br />

not at all, the lower pole collecting system may not<br />

opacify, and no discernible parenchyma will surround<br />

it (Nubbin sign). The appearance of the kidney may<br />

consequently resemble that of a non-duplex kidney<br />

with a lower polar mass or renal infarct.<br />

In computed tomography, the intervening renal<br />

parenchyma in a duplex kidney lacks a collecting<br />

system and major vessels. It is described as having a<br />

“faceless kidney” appearance, the collecting system in<br />

the nubbin or the mass effect of tissue at the pole [4] .<br />

Additional relevant findings include focal infarcts,<br />

cortical scars and atrophic scarred kidney. CT scan is<br />

superior to ultrasonography and excretory urography<br />

in diagnosing the lower pole nubbin [5] . In addition, the<br />

modality is helpful when function is poor or absent.<br />

CONCLUSION<br />

Careful history, examination and investigation may<br />

not rule out congenital abnormality of the kidneys like<br />

duplex collecting system. It may require a high index<br />

of suspicion as well as some invasive investigation<br />

to reach a final diagnosis. However, intra-operative<br />

findings can still surprise us with an entirely different<br />

diagnosis.<br />

ABSTRACT<br />

A 30-year-old female presented to the surgery outpatient<br />

department with complaint of pain in right iliac fossa of<br />

one day duration. The pain was associated with nausea and<br />

vomiting. On examination, there was localized tenderness<br />

and rigidity in the right iliac fossa with positive rebound<br />

tenderness. Multiple pigmentation of skin in the abdomen,<br />

accessory nipple and scoliosis were also noted. Laboratory<br />

investigation revealed neutrophilic leukocytosis. Ultrasound<br />

abdomen showed an appendix measuring 4 cm in length and<br />

a fibroid uterus. Diagnostic laparoscopy revealed an inflamed<br />

appendix with a small blind structure in continuity with the<br />

cecum. Operative diagnosis of double appendix was made.<br />

Microscopic examination confirmed double appendix with<br />

features of appendicitis and periappendicitis in the bigger<br />

appendix. We report this case because of it rarity. The surgical<br />

resident should be aware of this rare congenital anomaly<br />

to avoid missing the other appendix in appendectomy<br />

procedures and avoid its medico-legal consequences.<br />

KEY WORDS: appendicitis, congenital anomaly, double appendix<br />

INTRODUCTION<br />

Despite the notorious range of variation in<br />

character and position natural to the human vermiform<br />

appendix, the extremes of variation (absence or<br />

duplication) affect this <strong>org</strong>an so very rarely that they<br />

are worth mentioning and recording. Duplication of<br />

vermiform appendix is rare with reported incidence of<br />

0.004% [1] and may be associated with other congenital<br />

duplications or other anomalies [2] . Doubled appendix<br />

is usually asymptomatic. When symptomatic, they are<br />

usually the result of obstruction and inflammation.<br />

Majority of the cases are diagnosed at surgery or on<br />

postmortem examination. Some of them can be picked<br />

up preoperatively on barium enema. The clinical<br />

presentation can vary according to the location of the<br />

appendices [3] . Here we report a case of double appendix<br />

because of its extreme rarity and discuss its etiology<br />

and different types of anatomic presentation.<br />

CASE REPORT<br />

A 30-year-old female patient presented with<br />

right lower abdominal pain of one day duration<br />

with associated nausea and vomiting. She gave no<br />

history of change in bowel habits, urinary symptoms,<br />

menstrual disturbance or similar previous attacks.<br />

On examination she was afebrile. There was localized<br />

tenderness and rigidity with positive rebound<br />

tenderness in right iliac fossa. Multiple pigmentation<br />

of skin especially in the abdomen, accessory nipple<br />

(polythelia) and scoliosis were noted. No mass could<br />

be felt. Her pelvic examination did not reveal any<br />

positive findings. Laboratory investigations revealed a<br />

total white blood count of 24.8 x 10 9 cells per liter with<br />

neutrophilia (72%). Other laboratory investigations<br />

including blood urea, creatinine and liver function<br />

test were unremarkable. Ultrasound abdomen showed<br />

an appendix measuring 4 cm in length and a fibroid<br />

uterus with minimal localized collection of fluid, in the<br />

right iliac fossa.<br />

With a presumptive diagnosis of acute appendicitis,<br />

diagnostic laparoscopy was performed on the day of<br />

admission with insufflation of CO 2 gas and insertion<br />

of three trocars, two 10 mm ports and one 5 mm<br />

port. There was minimal fluid in the pelvis with an<br />

inflamed appendix, which could be easily identified.<br />

No evidence of perforation or mass formation was<br />

noted. However, another blind structure was seen<br />

in continuity with the cecum and was incidentally<br />

discovered during dissection of mesoappendix (Fig. 1).<br />

An operative diagnosis of double appendix was made.<br />

The operation was terminated after retrieval of the<br />

appendices with endopouch and exploration of rest<br />

of small and large bowels, which ruled out any other<br />

associated congenital anomaly. Her postoperative<br />

course was uneventful and she was discharged on<br />

postoperative day five.<br />

Gross pathological examination of the specimen<br />

showed duplex vermiform appendix (Fig. 2). The<br />

bigger appendix measured 5.1 cm and the small one<br />

measured 1.5 in length. Both the appendices were<br />

attached to mesoappendix in close proximity. The<br />

specimen displayed focal congestion in the serosal<br />

aspect of the bigger appendix. Microscopic examination<br />

revealed two lumina of appendices having two separate<br />

muscle coats and lymphoid follicles in the mucosa<br />

(Fig. 3). The bigger and longer appendix revealed<br />

mixed acute and chronic inflammatory infiltrate in<br />

the mucosa as well as in the muscle coat showing<br />

features of acute appendicitis with periappendicitis.<br />

The small one showed regular morphology without<br />

any inflammation. Thus the operative diagnosis of<br />

Fig. 2: Gross photograph of the double appendix. Arrow pointing<br />

double appendix was microscopically confirmed with<br />

one appendix showing features of acute appendicitis.<br />

DISCUSSION<br />

Duplication of the vermiform appendix, originally<br />

described in 1930, is rare with a reported incidence of<br />

0.004% [1] . The etiology of double appendix is unknown,<br />

but the most rational explanation was offered by Kelly<br />

and Hurdon who examined 54 human embryos to<br />

explain the origin and development of the appendix [4] .<br />

They described a minute budding “transient<br />

appendix” on the tip of the cecum in a 6-week-old<br />

embryo [4] . This small “transient appendix” usually<br />

atrophied or disappeared in the 8-week-old embryo [4] .<br />

Hence “transient appendix” is a definite potential<br />

for the embryological origin for the development of<br />

a supernumerary appendix and the most plausible<br />

explanation of the appendix duplex. Cave [5] classified<br />

three types of appendicular duplication as:<br />

Type A: Single cecum with one appendix exhibiting<br />

partial duplication<br />

Type B: Single cecum with two obviously separate<br />

appendices (complete duplicity)<br />

Type C: Duplication of cecum with each cecum bearing<br />

its proper appendix<br />

The simplest illustrations of the first type are those<br />

curious specimens of ‘double-barrelled’ appendix<br />

wherein the single <strong>org</strong>an presents two distinct<br />

lumina throughout either length or throughout only<br />

a part thereof [5] . The second type was first recorded by<br />

Paterson and Emrys-Robert (1906) wherein a full-term<br />

fetus, the subject of ectopia viscerum, spina bifida and<br />

other congenital anomalies showed a small ‘sacculated<br />

and curved appendix’ lying on each side of the ileocecal<br />

junction [5] . Type C was first reported by Greig<br />

(1934) in which the whole bowel duplicates distal to<br />

the site of Meckel’s diverticulum; two separate ceca<br />

were present, each bearing its proper vermiform<br />

appendix [5] .

Double Appendix: Report of a Case<br />

<strong>December</strong> <strong>2012</strong><br />

Wallbridge [6] modified Cave’s [5] original<br />

classification of duplicated vermiform appendix into<br />

three types as follows:<br />

A: Partial duplication of the appendix on a single<br />

cecum<br />

B: Single cecum with two completely separate<br />

appendices<br />

B1: “Bird-like appendix” called so because of its<br />

resemblance to the normal arrangement in birds,<br />

where there are two appendices symmetrically<br />

placed on either side of the ileo-cecal valve<br />

B2: One appendix arises from the usual site on the<br />

cecum, with another rudimentary appendix arising<br />

from the cecum along the line of the tenia at varying<br />

distance from the first<br />

C: Two ceca, each bearing its own appendix<br />

Though majority of the cases are diagnosed at<br />

surgery or on postmortem examination, some of the<br />

cases can be picked up preoperatively on barium enema.<br />

Peddu et al reported an incidental finding of Type B1<br />

double appendix by barium enema in a 73-year-old<br />

man who was investigated for the rectal bleeding [7] .<br />

In such cases the patient may be informed about the<br />

abnormality; however the role of conventional /<br />

laparoscopic appendectomy for the removal of the<br />

asymptomatic double appendix has not been welldefined.<br />

Although preoperative diagnosis could be<br />

made with the aid of radiological studies such as a<br />

barium enema, in cases associated with duplication<br />

of colon, the majority of cases have been diagnosed at<br />

surgery or upon pathological examination [8] .<br />

The present case represents type B2 of appendicular<br />

duplication, thought to represent the persistence of the<br />

“transient appendix”. Duplication of the vermiform<br />

appendix must be distinguished from a solitary<br />

diverticulum of the cecum [5,6] . True double appendices<br />

have lymphoid tissue and muscular walls, but a cecal<br />

diverticulum does not contain lymphoid tissue and is<br />

merely an out-pouching of mucosa and submucosa<br />

through a muscular defect [5,6] . In the current case, there<br />

were two separate appendices which were proved<br />

microscopically.<br />

Some cases of double appendix are associated with<br />

intestinal, genitor-urinary or vertebral malformation [8,9] .<br />

We should be aware of these possible malformations<br />

and the patient should be explored for the same at<br />

time of operation. The risk of associated malformation<br />

seems to be greater in young children, especially those<br />

with type B1 and C malformations [9] . In our present<br />

case, double appendix was incidentally found while<br />

performing laparoscopic appendectomy and we did<br />

not find any other gastrointestinal congenital anomalies<br />

like intestinal duplications that were commonly<br />

associated with double appendix. But she had other<br />

anomalies like scoliosis and skin lesions which were<br />

recorded for further notification with double appendix<br />

in the future. Kothari et al [3] reported duplex appendix<br />

in association with imperforate anus [3] .<br />

In patients with double appendix, when only a<br />

single appendix is found to be inflamed on exploration<br />

or laparoscopy, both the appendices should be<br />

removed so as to avoid diagnostic confusion that may<br />

arise on removal of a single appendix [10] . To the best of<br />

our knowledge, surgical management for the double<br />

appendix is same as the conventional / laproscopic<br />

appendectomy. No literature describes any unique<br />

technique for double appendix differently. However,<br />

one should explore for the possible associated<br />

malformation. In the current case, only the bigger and<br />

longer appendix was inflamed, however we removed<br />

both the appendices including the smaller noninflamed<br />

one.<br />

CONCLUSION<br />

Double appendix is extremely rare. Surgical<br />

residents should be aware of the possibility of<br />

duplication of appendix to avoid missing double<br />

appendix and its medico-legal consequences.<br />

Oncocytic and Clear Cell Areas in a Solid Pseudopapillary<br />

Tumor of the Pancreas: A Case Report<br />

ABSTRACT<br />

Solid pseudopapillary tumor (SPT) of pancreas is a rare,<br />

distinct, low-grade malignant neoplasm. Variable areas<br />

like clear cell foci can exist in this tumor, which can easily<br />

mislead the pathologist. Diagnosis of the same is important<br />

to distinguish from other clear cell lesions in the pancreas.<br />

Oncocytoid differentiation is rarer still and can raise doubts<br />

about the diagnosis, especially on trucut biopsies. Herein,<br />

we discuss a case of SPT of the pancreas exhibiting variable<br />

cellular morphology, of which very few cases have been<br />

reported in world literature.<br />

KEY WORDS: oncocytic, pancreas, solid pseudopapillary tumor<br />

INTRODUCTION<br />

Solid pseudopapillary tumor (SPT) is an uncommon,<br />

low-grade malignant neoplasm accounting for 1% of<br />

all exocrine pancreatic tumors. Exact histogenesis of<br />

this tumor remains uncertain [1] . As the various names<br />

for the tumor suggest, it is a solid and cystic pancreatic<br />

neoplasm with characteristic pseudopapillae and sheets<br />

of intermediate and small sized polygonal cells with<br />

minimal morphological deviation. Herein, we report a<br />

case of oncocytic variant of this tumor on account of its<br />

rarity and the few cases reported till date.<br />

CASE HISTORY<br />

A 29-year-old lady presented to the surgical outpatient<br />

department, with a history of swelling in the<br />

upper abdomen of one month duration, which was not<br />

associated with pain, vomiting or abdominal distention.<br />

Patient had a past history of exploratory laparotomy<br />

10 years ago, for palliative gastrojejunostomy and<br />

enterostomy in view of biopsy reported as suspected<br />

neuroendocrine tumor of pancreas, which, however,<br />

was not removed. On examination, a firm to hard mass<br />

of 10 x 7 cm, moving with respiration was palpated<br />

in the left hypochondrial region. All routine laboratory<br />

investigations were within normal range except an ESR<br />

of 40. Ultrasound abdomen was normal and upper GI<br />

endoscopy revealed extraluminal compression on<br />

stomach. A CT-scan revealed a cystic neoplasm arising<br />

from the head of pancreas and a clinical diagnosis<br />

of cystic neoplasm of mucinous origin of pancreas<br />

was made, in view of which the patient underwent<br />

Whipple’s pancreatectomy. Post-operative period<br />

was uneventful and the patient was discharged on<br />

the tenth post-operative day. The patient had no fresh<br />

complaints on follow-up after two months. However,<br />

she presented with amenorrhea after four months,<br />

post-operatively. On ultrasonography, polycystic<br />

ovaries were detected and she was advised for weight<br />

reduction. The patient was lost to follow-up after that.<br />

Pathological findings<br />

Gross: The tumor was well-demarcated, nodular and<br />

unencapsulated, weighing 911 grams and measuring<br />

16 x 11 x 10 cm. Cut section showed a multiloculated<br />

cystic tumor with variegated appearance comprising<br />

grey-white, friable irregular solid areas, yellow areas<br />

and hemorrhagic foci and peripheral rim of pancreatic<br />

tissue.<br />

Microscopy: Sections showed a well demarcated<br />

but unencapsulated tumor composed of sheets and<br />

trabeculae of loosely cohesive polygonal cells with<br />

central ovoid nuclei, few with eccentrically placed<br />

nuclei and finely stippled or granular chromatin.<br />

Focal clear cell areas (Fig. 1) were identified with<br />

abundant cytoplasmic, PAS and mucicarmine negative<br />

vacuoles and rare mitotic figures, separated by bands<br />

of hyalinised fibrous tissue with myxoid changes.<br />

Areas showing solid nests of polygonal cells with<br />

abundant eosinophilic granular cytoplasm and central<br />

vesicular nucleus with prominent nucleolus were<br />

our diagnosis (Fig. 4).<br />

seen (Fig. 2). Extensive cystic degeneration with<br />

classical pseudopapillae were seen, which helped<br />

clinch the diagnosis (Fig. 3). Immunohistochemistry<br />

(IHC) performed revealed tumor cells to be positive<br />

for vimentin, and negative for endocrine markers<br />

(synaptophysin, chromogranin) and the epithelial<br />

marker, cytokeratin. Further immunohistochemical<br />

markers were later done, including CD117, CD10 and<br />

DISCUSSION<br />

The first cases of SPT of the pancreas were<br />

described by Frantz [2] . Various synonyms include solid<br />

and papillary neoplasm, solid and papillary epithelial<br />

neoplasm, papillary-cystic carcinoma, solid and cystic<br />

acinar cell tumor of the pancreas relating to gross<br />

features and most obvious histological pattern. WHO,<br />

in 1996, proposed the name ‘solid-pseudopapillary<br />

neoplasm to encompass the two most conspicuous<br />

histological features [3] . They account for < 1% of all<br />

pancreatic neoplasms [4] . It is most common in women<br />

(82%) about 30 years of age but, occasionally, the tumor<br />

occurs in older women, men or children [5] .<br />

Although the pathogenesis is so far unknown,<br />

studies have thrown new insights regarding the same,<br />

the most acceptable being of pancreatic duct origin<br />

due to the related strong expression of galectin-3 by<br />

the neoplastic cells [6] .<br />

SPT on fine needle aspiration (FNA) and trucut<br />

biopsy samples can often mimic neuroendocrine<br />

tumors [7] , especially if the classical areas have not been<br />

sampled, as may have been the case in this patient,<br />

who was earlier misdiagnosed.<br />

Microscopically, classical areas are characterized by<br />

pseudopapillae and solid sheets of medium to small<br />

sized polygonal cells with vesicular nucleus and rare<br />

mitotic figures. This case was distinguished by the<br />

presence of focal areas with large polygonal cells with<br />

abundant eosinophilic granular cytoplasm and few<br />

with prominent nucleoli, along with areas showing<br />

multiple cytoplasmic vacuoles of varying sizes in many<br />

neoplastic cells. The vacuoles did not contain glycogen<br />

or mucin. Clear cells with cytoplasmic vacuoles are<br />

seen as a focal change in the classical form of SPT. They<br />

are formed by dilatation of the smooth endoplasmic<br />

reticulum and mitochondria [1] . Another source of clear<br />

cells is foamy macrophages. The differential diagnosis<br />

included clear cell endocrine pancreatic neoplasms<br />

with small lipid droplets and chromogranin positive<br />

neurosecretory granules [7] . Clear cell variant of<br />

ductal carcinoma of pancreas is distinguished by the<br />

presence of malignant cells with stromal desmoplasia,<br />

cytologic atypia, increased mitotic activity and areas<br />

of mucin-producing ductal carcinoma. Although<br />

serous cystadenoma is composed of clear cells, they<br />

contain glycogen and line small or large cystic spaces.<br />

Metastatic renal cell carcinoma should be considered<br />

in older individuals with cells showing lipid.<br />

Oncocytic areas in SPT have been recently described.<br />

Oncocytic changes may mean a favorable prognosis<br />

in neoplasms. It is seen in pancreatic neoplasms,<br />

and has been reported in acinar cell carcinoma,<br />

pancreatoblastoma, and intraductal oncocytic papillary<br />

neoplasm of the pancreas [8] . Oncocytic acinar cell<br />

carcinomas are usually solid, do not have a papillary<br />

and / or glandular component and are clinically<br />

aggressive [8] . Intraductal oncocytic papillary neoplasm<br />

of the pancreas is composed of cystically dilated ducts<br />

with long, thick papillae with fibrovascular cores,<br />

lined by cells with eosinophilic granular cytoplasm,<br />

and single eccentric nuclei [8] . Other unusual cell types<br />

described in SPT include pleomorphic spindle cells<br />

and cells with melanocytic differentiation [1] .<br />

IHC shows strong vimentin and CD10 positivity<br />

of SPT tumor cells, negativity for chromogranin, and<br />

weak or focal positivity for epithelial markers. Of late,<br />

SPT has been found to be positive for CD117 and cyclin<br />

D1 [9] . The clinical features, gross characteristics and<br />

immunoprofile of all the variants are similar to those<br />

of the classical SPT.<br />

CONCLUSION<br />

This is an interesting case of SPT of the pancreas<br />

diagnostic difficulty, especially on trucut biopsies.<br />

Clinicopathological correlation, microscopic pattern,<br />

extensive search for classical, non-oncocytic areas of<br />

ABSTRACT<br />

Celiac disease (CD) is one of the most common immune<br />

mediated diseases. This disease is triggered by ingestion of<br />

wheat gluten and related other cereal proteins, particularly<br />

those in rye and barley. The prevalence of CD in type 1<br />

diabetes in children is 1:6 to 1:103 and in adults 1:16 to<br />

1:76. In-spite of that, there is no current clinical evidence<br />

supporting routine screening of adult type 1 diabetic patients<br />

for CD. Most patients who have diabetes and CD have nonclassic<br />

forms of CD, with various presentations such as short<br />

stature, sideropenic anemia, or hypertransaminasemia; in<br />

many cases, patients are totally symptom free. CD elevates<br />

the mortality risks of a wide array of diseases in CD patients.<br />

This case had an atypical presentation of CD, and died<br />

unexpectedly because of the disease. We report this case to<br />

emphasize on the value of high index of suspicion of CD in<br />

type 1 diabetes mellitus.<br />

KEY WORDS: diet, gluten free, immune-mediated diseases, tissue, transglutaminase<br />

INTRODUCTION<br />

Celiac disease (CD) is one of the most common<br />

immune-mediated diseases [1] . Atypical asymptomatic<br />

form and absent gastrointestinal manifestations, are<br />

common, and a case may be discovered on duodenal<br />

biopsy for any other reason or immunology screening [2] .<br />

Studies in the United States and Europe show the<br />

prevalence of the disease approaching 1% [3,4] .<br />

Based on small bowel biopsy diagnosis, the<br />

prevalence of CD in type 1 diabetes in children is 1:6<br />

to 1:103 and in adults 1:16 to 1:76 [5] . CD is most often<br />

present before the onset of diabetes. Most patients who<br />

have both diabetes and CD have non-classic forms of<br />

CD, with various presentations such as short stature,<br />

sideropenic anemia, or hypertransaminasemia; in many<br />

cases, patients are totally symptom free [6] . In-spite of<br />

that, there is no current clinical evidence supporting<br />

routine screening of an adult type 1 diabetic patient for<br />

CD [7] .<br />

CASE HISTORY<br />

A twenty-two-year old Kuwaiti single female<br />

presented to us in the outpatient department with<br />

abdominal pain, bilateral lower limb edema and skin<br />

pigmentation of two months duration. She was known<br />

case of type 1 diabetes mellitus for 13 years on intensive<br />

insulin regimen, but non-compliant to her medication<br />

and with poor glycemic control. She had irregular<br />

menstruation and good scholastic performance. Her<br />

body weight was 42 kg, height was 158 cm and body<br />

mass index was 16.8 kg/m 2 . On clinical examination,<br />

she was conscious, alert and oriented. Her BP was<br />

110/70 mmHg, pulse rate was 75 bpm, temperature<br />

was 36.8 ºC and respiratory rate was 22/min. General<br />

examination revealed bilateral lower limb pitting<br />

edema with brownish, patchy and scaly pigmentation<br />

on the extremities but without pruritus. There was<br />

neither lymphadenopthy nor thyroid enlargement.<br />

Examination of the chest, heart, abdomen and CNS<br />

was unremarkable. Routine urine examination was<br />

unremarkable. Liver function tests showed an elevation<br />

of ALT ( 85 IU/l, normal up to 45 IU/l), AST ( 58 IU/<br />

l, normal up to 40 IU/l) and ALP (181 IU/l, normal<br />

up to 132 IU/l), with decreased plasma albumin to (18<br />

g/l, normal 35 - 50 g/l). Total bilirubin was 11 μmol/<br />

l (normal upto 17 μmol/l) and direct bilirubin was 3<br />

μmol/l (normal upto 5 μmol/l). INR was elevated to<br />

2.3. 24-hour urinary protein was normal (160 mg/day).<br />

Complete blood picture showed a hemoglobin level of<br />

123 g/l (normal female range 135 - 150 g/l), WBC count<br />

was 7400/mm 3 (normal range 4000 – 11,000/mm 3 ) and<br />

platelets were 230,000/mm 3 (normal range 150,000 –<br />

450,000/mm 3 ). Abdomen and pelvic ultrasonography<br />

was unremarkable, Investigations for hepatitis A, B<br />

and C, antinuclear antibodies and anti-double strand<br />

antibodies were negative. α -1 antitrypsin and serum<br />

ceruloplasmin were within normal limits. Serum<br />

protein electrophoresis was normal. Further enquiry<br />

into patient’s history, revealed that the patient had<br />

frequent attacks of diarrhea over the previous three<br />

months.<br />

The common association of CD with type 1 diabetes<br />

mellitus attracted our attention to the possibility of<br />

this disorder as a cause of the presenting picture of<br />

this patient. Anti-gliadin antibodies were evaluated<br />

together with anti-endomysial antibodies and tissue<br />

transglutaminase antibodies (tTGA). Anti-gliadin<br />

antibodies were elevated (IgA 62 u/l, normal < 5 u/l)<br />

IgG was 69 u/l (normal < 7 u/l), anti-endomysial<br />

antibodies were positive and tTGA were elevated (IgA<br />

was > 120 u/l, normal < 7 u/l). These findings were<br />

highly suggestive of CD. We proceeded for upper<br />

gastrointestinal endoscopy with duodenal biopsy for<br />

histopathology which showed nearly complete villous<br />

atrophy with intraepithelial lymphocytic infiltration.<br />

The patient was diagnosed to have CD with elevated<br />

liver enzymes as a result. Further investigations showed<br />

decreased level of vitamin D (41.45 nmol/l, normal<br />

50 - 80 nmol/l) and serum iron (3 μmol/l, normal 6<br />

– 7 μmol/l). A dietitian and gastroenterologist were<br />

consulted and gluten free diet (GFD) was started for the<br />

patient with multivitamin supplementation including<br />

vitamin D, K, folic acid, and iron.<br />

Four weeks later, although liver enzymes became<br />

normal, we were informed by the mother that her<br />

daughter was poorly compliant for GFD.<br />

Five weeks after diagnosis, the patient was admitted<br />

to the hospital because of urinary tract infection,<br />

diarrhea and increasing lower limb edema. Clinical<br />

examination was unremarkable except for bilateral<br />

lower limb pitting edema and brownish patchy scaly<br />

skin pigmentation on the extremities. Plasma albumin<br />

was as low as 15g/dl. Random blood sugar was 12.7<br />

mmol/l with no acetone in urine and blood pH was<br />

7.39. CBC showed Hb of 12.1g/dl WBCs 15,000/mm 3<br />

(85% were polymorhs) and platelets were 235,000/mm 3 .<br />

Urine culture and sensitivity were sent. Empirical<br />

antibiotic ciprofloxacin 500 mg BD was started and this<br />

choice was confirmed by the result of urine culture and<br />

sensitivity test. IV albumin 20 g twice daily was started<br />

with intensive insulin regimen.<br />

The patient became distressed after six days of<br />

admission with a temperature of 38.1 ºC and hypoxia.<br />

X-Ray chest showed bilateral bronchopneumonia.<br />

Patient was shifted to the ICU and ventilated as her<br />

respiratory rate had reached 35/min. Antibiotics<br />

were modified to Tazocin 4.5 g/6 hourly and IV<br />

clarithromycin 500 mg BD. Tracheal aspirate was<br />

sent for culture and sensitivity test along with blood<br />

culture and sensitivity. The patient did not respond<br />

well to antibiotics, and deteriorated within two days<br />

and died. Result of tracheal aspirate and blood culture<br />

showed Klebsiella pneumoniae.<br />

DISCUSSION<br />

CD is triggered by ingestion of wheat gluten<br />

and related other cereal proteins, particularly<br />

those in rye and barley. These molecules induce an<br />

inflammatory response in the small intestine, resulting<br />

in villous atrophy, crypt hyperplasia and lymphocytic<br />

infiltration [1] . CD is sometimes divided into clinical<br />

subtypes. The terms classic apply to cases which<br />

meet the classic features of CD, which include chronic<br />

diarrhea, abdominal distension and pain, weakness<br />

and sometimes malabsorption. In contrast in atypical<br />

asymptomatic form, no gastrointestinal manifestations<br />

are present, but features such as anemia, osteoporosis,<br />

short stature, infertility and neurological problems are<br />

common, and a case may be discovered on duodenal<br />

biopsy for any other reason or immunology screening.<br />

Nevertheless, the disease remains widely underrecognized<br />

[2] .<br />

Studies in the United States and Europe show the<br />

prevalence of the disease approaching 1% [3,4] . Based<br />

on small bowel biopsy diagnosis, the prevalence of<br />

CD in type 1 diabetes in children is 1:6 to 1:103 and in<br />

adults is 1:16 to 1:76 [5] . CD is most often present before<br />

the onset of diabetes [6] . The association between the<br />

development of both diseases may be explained by<br />

the inheritance of common major histocompatibility<br />

complex immunogenotypes that influence the<br />

presentation of auto antigens to CD4 + T-Cells [7] .<br />

In adults with CD, hypertransaminasemia is<br />

frequent and normalizes with gluten free diet. If not,<br />

liver biopsy should be done to rule out autoimmune<br />

hepatitis and primary billiary cirrhosis [8] . Isolated<br />

elevation of ALP (alkaline phosphatase) is less<br />

common and may reflect presence of secondary<br />

hyperparathyroidism (bone-specific form).<br />

Hypoalbuminemia and prolonged prothrombin time<br />

may indicate severe form of malabsorption [9] .<br />

The American Gastroenterological Association<br />

(AGA) Institute recommended that testing for CD<br />

should be considered in symptomatic patients who are<br />

at particular risk. These include those with unexplained<br />

iron deficiency anemia, premature osteoporosis, Down<br />

syndrome, unexplained hypertransaminasemia,<br />

autoimmune hepatitis and primary billiary cirrhosis.<br />

The diagnostic tests for CD widely used now<br />

include IgA antiendomysial antibodies and IgA tTGA<br />

(sensitivity - 90% and specificity - 95%), but distal<br />

duodenal biopsy remains the gold standard diagnostic<br />

method (showing total or partial villous atrophy,<br />

crypt lengthening and increased lymphocytes in<br />

lamina propria and intraepithelial region). Biopsy is<br />

indicated even if serology is negative and CD is still

highly suspected. Compliance with GFD is likely to<br />

be protective against development of non-Hodgkin<br />

lymphoma and dermatitis herpitiformis in CD. It<br />

can improve nutritional status, body mass index,<br />

increase insulin requirement in type 1 diabetes, but no<br />

convincing change in diabetes control [10] .<br />

CD patients have overall, two-fold increased<br />

mortality risk compared with the general population.<br />

CD elevates the mortality risks of a wide array of<br />

diseases in CD patients, including non-Hodgkin<br />

lymphoma (SMR 11.4), small intestinal cancer (SMR<br />

m 17.3), autoimmune diseases as rheumatoid arthritis<br />

(SMR 7.3) and diffuse disease of connective tissue (SMR<br />

17.0), allergic disorders such as bronchial asthma (SMR<br />

2.8), inflammatory bowel disease including ulcerative<br />

colitis and Crohn’s disease (SMR 70.9), diabetes<br />

mellitus (SMR 3.0), disorders of immune-deficiency<br />

(SMR 20.9), tuberculosis (SMR 5.9), pneumonia (SMR<br />

2.9) and nephritis (SMR 5.4) [11] .<br />

CONCLUSION<br />

It is important to have a high index of suspicion<br />

for CD in adult patients with type 1 diabetes mellitus,<br />

in view of the common association between these two<br />

diseases and the elevated mortality risks for a wide<br />

array of diseases in CD patients.<br />

ABSTRACT<br />

Most primary penile malignancies are squamous cell<br />

carcinoma (SCC) and occur most often during the 6 th and 7 th<br />

decades of life. Uncircumcised men are more often affected,<br />

probably because of the chronic irritative effect of smegma. An<br />

association between human papilloma viruses 16 and 18 and<br />

SCC of the penis has also been reported. We describe a case of<br />

a 43-year-old uncircumcised Asian male patient who presented<br />

with an ulcerating penile mass. MRI images were helpful in<br />

making a preoperative diagnosis of penile cancer. MR imaging<br />

can play an important role in the evaluation of a penile mass.<br />

KEY WORDS: penile mass, penile SCC, MRI of penis<br />

INTRODUCTION<br />

Squamous cell carcinoma (SCC) of the penis usually<br />

begins on the glans as a focal epithelial thickening<br />

with or without ulceration [1] . The lesions are generally<br />

not painful, and affected patients often delay seeking<br />

medical attention [2] . After penectomy with 2 cm<br />

margins, patients with tumors that have not invaded<br />

the corpora cavernosa have a greater than 95% 3-year<br />

survival rate [3] . Survival decreases markedly with<br />

cavernosal invasion or with spread to regional lymph<br />

nodes [4] . Although not often performed in the acute<br />

setting, MR imaging can play an important role in the<br />

evaluation of penile mass [5] . Ultrasound (US) can help<br />

detect solid penile mass in the majority of patients [6] .<br />

CASE HISTORY<br />

An Indian uncircumcised male patient aged 43<br />

years presented with a painless penile mass of sixmonth<br />

duration. The clinical examination revealed<br />

a solid mass lesion underneath the foreskin and the<br />

patient was referred to our department for an MRI. MRI<br />

revealed a solid isointense to low signal intensity mass<br />

lesion both on T1-wieghted (Fig. 1) and T2-wieghted<br />

(Fig. 2) images, mainly located at the left lateral aspect<br />

of the glans of the penis extending to its dorsal aspect<br />

with a definite invasion of the hypointense adjacent<br />

tunica albuginea (Fig. 3). However, the urethra was not<br />

compromised (Fig. 3). After Gd-chelate agent injection,<br />

homogenous enhancement pattern was elicited with<br />

multiple signal void foci that were confirmed to be<br />

hypervascular on color Doppler study (Fig. 3 and<br />

Fig. 4). The clinical examination revealed a solid mass<br />

lesion underneath the foreskin (Fig. 5) with concealed<br />

external meatus and with discharge from cutaneous<br />

fistula from the foreskin.<br />

Diagnosis and Treatment: Circumcision with<br />

excisional biopsy was done and histopathological<br />

examination confirmed penile SCC. So the patient<br />

underwent partial penectomy with 2 cm safety margin.<br />

The patient was planned for bilateral ilio-inguinal<br />

lymph node dissection.<br />

DISCUSSION<br />

Carcinoma of the urethra and penis is extremely<br />

rare, accounting for less than 1% of genitourinary<br />

cancers in males [7] . Histological examination reveals<br />

SCC in more than 95% of cases of penile carcinoma [8] .<br />

At MR imaging, SCC is usually hypointense relative<br />

to the corpora on both T1- (Fig. 1) and T2- (Fig. 2)<br />

weighted images. At contrast-enhanced imaging, these<br />

lesions do increase in signal intensity but less so than<br />

the normal corporal bodies. Although neither MR nor<br />

other imaging is generally needed for diagnosis (the<br />

tumor is usually visible at physical examination), MR<br />

imaging may be performed for staging purposes. In the<br />

commonly used Jackson staging system, stage I lesions<br />

are confined to the glans or prepuce, stage II lesions<br />

depict pelvic lymphadenopathy, but MR imaging is<br />

superior for evaluation of the primary lesion [10] .<br />

Fig. 5: Exploration of the mass before operation<br />

CONCLUSION<br />

Regardless of the <strong>org</strong>an of origin, MRI aids in<br />

the delineation of the extent of tumor dissemination,<br />

enabling detection of invasion into the corpora<br />

cavernosa or tunica albuginea. As mentioned previously,<br />

surgical treatment of carcinoma of the penis consists of<br />

either partial or total penectomy. Follow-up physical<br />

examination to look for local recurrence is limited in<br />

allowing the detection of pelvic lymphadenopathy and

deep recurrence. Therefore, cross-sectional imaging is<br />

often performed. In addition to identification of sites<br />

of tumor recurrence, MR imaging can be helpful in<br />

the identification of normal post-surgical findings.<br />

Complications of surgery of the lower urinary tract can<br />

also be shown clearly with MR imaging.<br />

Unstable Carpometacarpal Dislocation of Ulnar<br />

Four Fingers – An Easily Overlooked Injury<br />

ABSTRACT<br />

Multiple carpometacarpal (CMC) joint dislocations are<br />

rare. These clinical entities require significant amount of<br />

force to produce dislocation at this inherently stable joint<br />

level. We present a case of unstable dorsal dislocation<br />

of ulnar four carpometacarpal joints without associated<br />

fractures which was fixed with multiple K-wires with good<br />

functional outcome. Although carpometacarpal dislocations<br />

are uncommon entities, the case is reported here not just by<br />

virtue of its rarity but also because of a tendency for such<br />

injuries to be overlooked by surgeons with resultant delay in<br />

diagnosis and treatment.<br />

KEY-WORDS: internal fixation, k-wire<br />

INTRODUCTION<br />

Carpometacarpal (CMC) dislocations other than<br />

thumb are uncommon injuries accounting for less<br />

than 1% of hand injuries. It is rare for multiple CMC<br />

dislocations to occur without associated fractures [1,2] .<br />

Disability is significantly severe in untreated cases and<br />

initially neglected cases. The dislocation of multiple<br />

joints at CMC junction is not an anticipated diagnosis<br />

in cases of polytrauma with hand swelling. The injury<br />

is often missed or overlooked owing to many factors,<br />

both on the surgeon’s side and patient’s side [3] .<br />

CASE HISTORY<br />

A 26-year-old male presented to the emergency<br />

department after riding his motorbike into a roadside<br />

vehicle with gross swelling on the dorsum of the<br />

right hand and inability to move the wrist. The<br />

wrist movements were grossly restricted but finger<br />

movements were elicitable with pain. Distal hand<br />

perfusion was adequate.<br />

After adequate first aid measures, an X-ray of<br />

the hand in antero-posterior and oblique plane<br />

was ordered. Hand radiographs primarily revealed<br />

no bony injury as screened by emergency medical<br />

officer against awaited metacarpal fracture. A dorsal<br />

splint was applied taking cognizance of severe hand<br />

contusion. Screening of radiographs by consultants<br />

gave a clue to missed diagnosis of CMC dislocation.<br />

There was overlapping of joint surface of metacarpal<br />

bases over carpals. The lateral view hand radiograph<br />

promptly clarified diagnosis of CMC dislocation of<br />

ulnar four fingers. Lateral radiograph revealed a<br />

significant dorsal offset of metacarpal complex over<br />

carpals. There was no associated fracture of adjacent<br />

CMC entities (Fig. 1A, B)<br />

An unsuccessful closed reduction with slab<br />

application was attempted with linear traction along<br />

line of fingers. The reduction could only be maintained<br />

with multiple trans-CMC Kirschner wires (K-wires)<br />

(Fig. 1C). Postoperatively, wrist was splinted on dorsal<br />

side for six weeks; K-wires were removed at the end of<br />

six weeks. Reduction was satisfactorily sustained after<br />

slab removal as confirmed by check radiographs. Full<br />

range of motion of hand was regained with support<br />

of active hand-specific physiotherapy in the early<br />

convalescent period showing excellent functional<br />

result (Fig. 2A, B).<br />

DISCUSSION<br />

Less commonly encountered injury of CMC<br />

dislocation gains importance in emergency scenarios<br />

by virtue of it getting overlooked and a resultant<br />

delayed diagnosis. The delayed diagnosis and<br />

consequent delayed treatment of this joint dislocation<br />

has implications in functional outcome of wrist [4] .<br />

Many factors play a role in such uninvited<br />

overlook. Occurrence in settings of polytrauma,<br />

revealing antero-posterior and oblique radiographs of<br />

hand, gross swelling of hand are incriminating factors.<br />

Literature also suggests repeated mistakes with this<br />

diagnosis even by experts [3] .<br />

Multiple CMC dislocations are often a high energy<br />

trauma often occurring in motorcyclists and boxers.<br />

Deduced pathway of injury appears to be forceful<br />

impact on metacarpal bases with a closed fist [5] . The<br />

patient will often have a diffuse swelling of dorsum of<br />

hand and distal forearm. It may be fluctuant depicting<br />

a hematoma collection. The characteristic hump of<br />

dislocation at root of hand is often masked by swelling<br />

of hand and forearm.<br />

Routinely ordered X-rays in antero-posterior<br />

and oblique plane suggest the diagnosis. Lateral<br />

projection radiograph will confirm the multiple CMC<br />

dislocations in suspicious cases [6] . Often dislocation<br />

is dorsal. There can be associated fracture of adjacent<br />

carpal or metacarpal bones. The clues for such an<br />

obscure diagnosis are loss of parallelism between joint<br />

spaces at base of metacarpals and carpals. There will<br />

be an overlap of joint surfaces of base of metacarpals<br />

over carpus. There can be appreciable offset of fifth<br />

metacarpal base as in our case [3,7] . A lateral radiograph<br />

will affirm the misalignments of metacarpals over<br />

carpus.

Unstable Carpometacarpal Dislocation of Ulnar Four Fingers – An Easily Overlooked Injury<br />

<strong>December</strong> <strong>2012</strong><br />

Dislocation at CMC level essentially needs emergent<br />

reduction as soon as it is diagnosed. Failure to do so<br />

may result in impaired functional ability of hand,<br />

impaired grip, loss of transverse and longitudinal<br />

arches of hand and stiffness of hand. Danger of ulnar<br />

nerve injury in proximity of 5 th CMC joint and reflex<br />

sympathetic dystrophy will always be there [3,8] .<br />

Closed reduction is successful in fresh dislocations<br />

less than 10 days old. It can be maintained in plaster<br />

cast in majority cases. Intraoperatively ascertained<br />

unstable dislocations can be supplemented with trans-<br />

CMC K-wires along with external immobilisation. Late<br />

presentations and irreducible dislocations will require<br />

open relocation [1,7,9] . Removal of external splint and<br />

K - wires can be done as early as six weeks. An early<br />

physiotherapy will hasten rehabilitation of hand. Good<br />

functional results can be expected in properly treated<br />

cases with anatomical reduction.<br />

CONCLUSION<br />

Diagnosis of CMC dislocation requires a high<br />

index of suspicion, careful examination and good<br />

radiography. Otherwise, the outcome will be inferior.<br />

The treatment will require a relocation of joint<br />

structures on emergency basis and its maintenance to<br />

ensure a favourable outcome.<br />

ABSTRACT<br />

We report a rare case of a collision tumor. Our patient was<br />

found to have prostatic adenocarcinoma colliding with<br />

chronic lymphocytic leukemia, with no previous risk factors<br />

or even a clinical suspicion. We review the literature for<br />

similar cases and make an attempt to address the possible<br />

shared risk factors.<br />

KEYWORDS: collision tumors, multiple primaries,<br />

INTRODUCTION<br />

Synchronous involvement of the same tissue by two<br />

different tumors is rare, but has been well-reported [1] .<br />

Many examples of collision tumors having either prostatic<br />

adenocarcinoma or chronic lymphocytic leukemia were<br />

described, but only very rarely showed both neoplasms<br />

colliding together. Being a curious phenomenon which<br />

causes confusion in the diagnosis and treatment for<br />

physicians, with an ominous effect on the patient, we<br />

report this case in order to look for possible common risk<br />

factors and a proposed way of treatment.<br />

CASE REPORT<br />

A 76-year-old man, presented to the Jordan<br />

University Hospital in <strong>December</strong>, 2008 complaining of<br />

fatigue and weight loss of two months duration. He was<br />

a known case of diabetes mellitus. Physical examination<br />

demonstrated hepatosplenomegaly, but no enlarged<br />

lymph nodes. No urological findings were evident in<br />

history or physical examination. The initial workup<br />

showed abnormal complete blood count numbers.<br />

Hemoglobin concentration was 8.5 g/dl and the packed<br />

cell volume (PCV) was 25%. The white blood count<br />

was 22,000, out of which 77% were lymphocytes, while<br />

neutrophils formed 21% of blood cells. Platelet count was<br />

normal. The peripheral blood film showed microcytic<br />

hypochromic anemia, abnormal lymphocytes and<br />

normal platelets. Kidney and liver function tests were<br />

normal, with the exception of mild hypoproteinemia.<br />

Guaiac stool hemoccult test was negative. Urinalysis<br />

was normal.<br />

The peripheral blood film showed diffuse<br />

lymphocytosis. The lymphocytes were small and<br />

mature with numerous smudge cells and minimal<br />

atypia. Astonishingly, a bone marrow trephine biopsy<br />

demonstrated the same neoplastic lymphocytes<br />

intermingling with aggregates of large epithelioid cells<br />

(Fig. 1). Immunohistochemical study revealed the latter to<br />

be of prostatic origin (Fig. 2). Flow cytometry confirmed<br />

the diagnosis of chronic lymphocytic leukemia (CLL)<br />

(Fig. 3).<br />

The patient was retrospectively investigated for<br />

prostatic carcinoma. Serum total prostate specific antigen<br />

(PSA) was highly elevated (100), and pelvic magnetic<br />

resonance image (MRI) scan detected a prostatic mass<br />

and liver metastasis.<br />

DISCUSSION<br />

A collision tumor is defined as the co-existence of<br />

two adjacent but histologically different malignant<br />

neoplasms occurring in the same <strong>org</strong>an without<br />

histological admixture or an intermediate cell<br />

population zone [1] . It is termed collision tumor when<br />

the components are present in the originating <strong>org</strong>an<br />

and collision metastasis when they collide in a distant<br />

site discontinuous from the original <strong>org</strong>an. When<br />

both tumors fuse and intermingle to the extent that it<br />

is difficult to distinguish between them, the process<br />

then is called a composite tumor [1,2] . Another similar<br />

phenomenon is the hybrid tumor, which is composed<br />

of two different tumor entities, each of which conforms<br />

with an exactly defined tumor category and has<br />

an identical origin within the same topographical<br />

area [3] . This is different from multiphasic tumor<br />

which corresponds to one tumor entity with different<br />

morphological patterns. Discordant tumors are two<br />

impact on the diagnosis and modality of treatment,<br />

dozens of cases of collision tumors have been reported.<br />

Besides, an attempt to discover a relationship between<br />

the originating tumors is usually made.<br />

Our case does not fall under any definition, as<br />

it includes one primary and one metastatic tumor.<br />

However, as there is no strict definition for this situation<br />

in the literature, we prefer to consider it as collision<br />

tumor, and to restrict “collision metastasis” to cases<br />

when both tumors collide outside their primaries [4] .<br />

Prostatic carcinoma occurring together with CLL was<br />

reported in the literature [5-8] , but with different clinical<br />

scenarios. None of the previously reported cases showed<br />

a collision metastasis between prostatic carcinoma and<br />

CLL. We are unaware of a similar reported case where<br />

collision metastasis was the first hint for the presence of<br />

two hidden neoplasms.<br />

It was demonstrated that patients with CLL are<br />

susceptible to develop other primary malignancies. In<br />

the large study carried out by Hisada et al, 2% of patients<br />

with CLL developed prostate carcinoma, with a relative<br />

risk of 1.01 [9] . The study did not specify the relationship<br />

between the two neoplasms or the common risk factors<br />

between them. However, the relative increased incidence<br />

of both neoplasms in older ages, with the relative<br />

indolent course of CLL, may suggest this occurrence.<br />

The immune derangement status, believed to occur in<br />

CLL [7,9] would predispose to a second malignancy, though<br />

this relation is not well proved in prostatic carcinoma. A<br />

recent finding showed that deletion at 13q14 occurs in<br />

60% of prostatic carcinoma and more than 50% of CLL,<br />

suggesting a shared pathway at the molecular level [10] .<br />

Our patient received hormonal therapy for prostate<br />

carcinoma. He was unfit for chemotherapy for CLL.<br />

Unfortunately, the patient had tumor progression and<br />

died seven months later from extensive metastasis.<br />

CONCLUSION<br />

We conclude that a collision tumor of both CLL and<br />

prostate carcinoma exists, although rare. Physicians<br />

should be aware of the possible second malignancy in<br />

patients with CLL, and should not stop at peripheral<br />

blood smear findings alone.<br />

To date, little evidence is available about the<br />

association between peptic ulcer disease and<br />

commercially available cyclooxygenase-2 inhibitors<br />

(COX-2 inhibitors) in Taiwan. Therefore, we conducted<br />

this population-based cohort study from the National<br />

Health Insurance (NHI) program in Taiwan to directly<br />

compare the effects of individual COX-2 inhibitors on<br />

the risk of peptic ulcer disease. The details of insurance<br />

program can be found in previous studies [1-4] . This<br />

study consisted of 1388 patients aged 20 years or older<br />

who had ever used COX-2 inhibitors (770 men and<br />

618 women, mean age 51.4 years, standard deviation<br />

18.5 years), and 5403 subjects who never used COX-<br />

2 inhibitors (3080 men and 2323 women, mean age<br />

50.6 years, standard deviation 18.2 years), frequency<br />

matched with sex, age, and index year for comparison,<br />

from 2000 to 2006. The incidence of peptic ulcer disease<br />

(based on International Classification of Diseases<br />

9th Revision - Clinical Modification, ICD-9 531, 532,<br />

533, and 534) at the end of 2009 was determined. An<br />

index date for patients with peptic ulcer disease was<br />

defined as their date of diagnosis. Subjects diagnosed<br />

with peptic ulcer disease before the index date were<br />

excluded from the study. The subjects, who had ever<br />

used combination of COX-2 inhibitors, or ever used<br />

aspirin, or other non-steroidal anti-inflammatory<br />

drugs (NSAIDs), were excluded from this study. Other<br />

co-morbidities before the index date were defined as<br />

follows: Helicobacter pylori infection (ICD-9 041.86),<br />

tobacco use (ICD-9 305.1), and alcoholism (ICD-9 303,<br />

305.00, 305.01, 305.02, 305.03 and V11.3, and A-code<br />

A215). The potentially related medications included<br />

were as follows: proton pump inhibitor, histamine-2<br />

receptor antagonist, clopidogrel, ticlopidine, systemic<br />

corticosteroid, warfarin, and heparin.<br />

We found that the incidence of peptic ulcer disease<br />

was 3.26-fold higher in the COX-2 inhibitors group,<br />

compared with the non-COX-2 inhibitors group<br />

(19.28 per 1000 person-years Vs 5.91 per 1000 personyears,<br />

95% confidence interval - CI = 2.63 - 4.04). After<br />

controlling for variables that were significantly related<br />

to COX-2 inhibitors found in the Chi-square test, the<br />

multivariable Cox proportional hazard regression<br />

showed use of COX-2 inhibitors was substantially<br />

associated with increased risk of peptic ulcer disease<br />

(hazard ratio - HR = 3.23, 95% CI = 2.59 - 4.04). In<br />

sub-analysis, individual COX-2 inhibitors, including<br />

celecoxib (HR = 3.29, 95%CI = 2.00 - 5.39), meloxicam<br />

(HR = 3.19, 95%CI = 2.33 - 4.36), nabumetone (HR =<br />

3.19, 95% CI = 2.39 - 4.25), and nimesulide (HR = 2.21,<br />

95% CI = 1.08-4.52), would substantially increase the<br />

risk of peptic ulcer disease, respectively.<br />

Previous studies have reported that COX-2<br />

inhibitors can reduce the risk of upper gastrointestinal<br />

ulcers, compared with non-selective NSAIDs [5, 6] . In<br />

Rostom et al’s systematic review [7] , COX-2 inhibitors<br />

correlate with lower risk of upper gastrointestinal<br />

ulcers (relative risk, 0.26 - 0.39), compared with<br />

non-selective NSAIDs. An observational study by<br />

Hsiang et al in Taiwan [8] , the annual incidence of<br />

upper gastrointestinal ulcers in patients using COX-2<br />

inhibitors was 4.6%. In this present study, the overall<br />

risk of peptic ulcer disease was 3.23-fold higher in<br />

patients using COX-2 inhibitors, compared with nonuse<br />

of COX-2 inhibitors. In sub-analysis, patients who<br />

used celecoxib, meloxicam, or nabumetone for less<br />

than three months were at higher risk of peptic ulcer<br />

disease. As reported in the literature, celecoxib is more<br />

selective and safe than the other non-specific NSAIDs [5] .<br />

However, this present study showed that use of<br />

celecoxib had the highest risk of peptic ulcer disease.<br />

Because this is an observational study, we do not have<br />

a plausible explanation for this phenomenon.<br />

It is widely established that COX-2 inhibitors are<br />

only relatively rather than absolutely safe. These<br />

findings further alert clinicians about the risk of peptic<br />

ulcer disease when prescribing COX-2 inhibitors.<br />

Multiple sclerosis (MS) is a chronic and progressively disabling inflammatory autoimmune disorder of<br />

the central nervous system. MS has a multifactorial etiology and is triggered by environmental factors<br />

in individuals with complex genetic risk profiles. The epidemiology of MS changes with the spatial and<br />

temporal distribution of these genetic and nongenetic risk factors. This population-based matched casecontrol<br />

study aimed to determine the risk factors for MS in Kuwait. From May 2 to 9, 2010, we enrolled 101<br />

confirmed MS cases using the list frame maintained by the Multiple Sclerosis Association of Kuwait. For<br />

each case, two population controls individually matched for age (± 2 years), gender and nationality were<br />

selected. Data on demographic, socioeconomic variables, potential genetic and environmental factors were<br />

collected using a structured questionnaire. For a case, the questions were directed to the period that preceded<br />

the recognition of the disease, while for each of the two matched controls, a date of ‘pseudodiagnosis’ of<br />

MS was established, i.e. the date on which the control subject was of the same age as his/her matched case<br />

was at MS diagnosis and accordingly questions were directed to the preceding period. The multivariable<br />

conditional logistic regression model showed that compared with controls, the cases were significantly more<br />

likely to have a family history of MS [matched odds ratio (OR) adj<br />

= 6.7; 95% confidence interval (95% CI): 2.5<br />

- 18.0; p < 0.001] or have suffered from a head trauma in the past before MS diagnosis (matched OR adj<br />

= 2.6;<br />

95% CI: 1.2 - 5.5; p = 0.014). Furthermore, compared with controls, cases were significantly more likely to<br />

have stayed in Kuwait during the Iraqi invasion of 1990 (matched OR adj<br />

= 1.8; 95% CI: 1.1 - 3.5; p = 0.022).<br />

This study showed that a family history of MS, a history of head injury, and presence in Kuwait at the time of<br />

the Iraqi invasion of 1990 were associated with a significantly increased MS risk. Future retrospective cohort<br />

studies by using existing biological and epidemiological databases may provide a clue to MS etiology.<br />

The Gulf War brought about to the State of Kuwait some of the worst environmental pollution as a result of<br />

oil spill. Since 1995, research programs have been initiated to avoid further damage to the Kuwaiti desert<br />

and marine environment and to restore and rehabilitate the polluted land, water, and air ecosystems.<br />

During the following 15 years, different bioremediation methods both on laboratory and small field scales<br />

were tested and evaluated. The findings of these studies were implemented to establish a bio-park in<br />

which ornamental shrubs and trees were grown in bioremediated soil. This review will focus on Kuwait’s<br />

experience in rhizoremediation and its positive impacts on oil-contaminated sites.

Introduction: Cancer is the second cause of death in Kuwaiti people after cardiovascular diseases.<br />

This study is the first in the country to describe epidemiological measures related to cancer in this<br />

population.<br />

Methods: Data obtained from the Kuwait cancer registry included all Kuwaiti patients between years<br />

2000 - 2009. Analyses were conducted using age-specific rates, the age-standardization-direct method,<br />

95% confidence intervals (95% CI), cumulative risk by the age of 74 years, limited-duration prevalence,<br />

mortality and forecasting to year 2029.<br />

Results: It was noted that the commonest cancer sites were colorectal with an age standardized incidence<br />

rate (ASIR) of 16.1/100,000 in males and breast (49.4/100,000) in the female population. The trend of cancer<br />

incidence (1974 - 2009) showed no statistically significant change. First causes of death due to cancer were<br />

female breast 8(6.4 - 9.6)/100,000 and lung (males) 8.1/100,000 (6.6 - 10.0). The risk of developing cancer<br />

by the age of 74 was 13.4% (1/8) and 14.3% (1/7) in males and females respectively, and the risk of dying<br />

from cancer in the same age group was 1/17 and 1/23. By the end of 2009, prevalent cases represented<br />

0.52% of the Kuwaiti population. In the year 2029, the total number of cancer cases is expected to reach<br />

1200 cases compared to 889 cases in 2009.<br />

Conclusions and recommendations: The most common cancers in Kuwait (breast, colorectal and lung)<br />

are largely preventable. Prompt and effective interventional prevention programs that vigorously involve<br />

diet, anti-smoking and physical activity for both sexes are urgently required.<br />

PLoS One <strong>2012</strong>; 7(9):e43895. Epub <strong>2012</strong> Sep 10<br />

Background: Clinical audit can be of valuable assistance to any program which aims to improve the<br />

quality of health care and its delivery. Yet without a coherent strategy aimed at evaluating audits’<br />

effectiveness, valuable opportunities will be overlooked. Clinical audit projects are required as a part of<br />

the formative assessment of trainees in the Family Medicine Residency Program (FMRP) in Kuwait. This<br />

study was undertaken to draw a picture of trainees’ understanding of the audit project with attention to<br />

the knowledge of audit theory and its educational significance and scrutinize the difficulties confronted<br />

during the experience.<br />

Methodology/Principal Findings: The materials included the records of 133 audits carried out by<br />

trainees and 165 post course questionnaires carried out between 2004 and 2011. They were reviewed and<br />

analyzed. The majority of audit projects were performed on diabetic (<strong>44</strong>.4%) and hypertensive (38.3%)<br />

care. Regarding audits done on diabetic care, they were carried out to assess doctors’ awareness about<br />

screening for smoking status (8.6%), microalbuminuria (19.3%), hemoglobin A1c (15.5%), retinopathy<br />

(10.3%), dyslipidemia (15.8%), peripheral neuropathy (8.8%), and other problems (21.7%). As for audits<br />

concerning hypertensive care, they were carried out to assess doctors’ awareness about screening for<br />

smoking status (38.0%), obesity (26.0%), dyslipidemia (12.0%), microalbuminuria (10.0%) and other<br />

problems (14.0%). More than half the participants (68.48%) who attended the audit course stated that they


351<br />

Selected Abstracts of Articles Published Elsewhere by Authors in Kuwait <strong>December</strong> <strong>2012</strong><br />

‘definitely agreed’ about understanding the meaning of clinical audit. Most of them (75.8%) ‘definitely<br />

agreed’ about realizing the importance of clinical audit in improving patients’ care. About half (49.7%) of<br />

them ‘agreed’ that they can distinguish between ‘criteria’ and ‘standards’.<br />

Conclusion: The eight years of experience were beneficial. Trainees showed a good understanding of the<br />

idea behind auditing the services provided. They demonstrated their ability to improve the care given in<br />

health centers in which these projects were undertaken.<br />

Introduction: Infants represent an important risk group for influenza associated hospitalizations and<br />

mortality. This study evaluated the clinical presentations, hospitalization course and outcome of infants<br />

hospitalized with the pandemic influenza AH1N1 [Influenza A(H1N1)pdm09] in relation to their previous<br />

health status.<br />

Methodology: We conducted a retrospective chart review of hospitalized infants with laboratoryconfirmed<br />

Influenza A(H1N1)pdm09 infection in two hospitals in Kuwait. Demographic characteristics,<br />

pre-existing high-risk medical conditions, clinical presentations, complications and mortality were<br />

analyzed. Previously healthy infants’ data were compared with infants with pre-existing high-risk medical<br />

conditions for severity of the illness and outcome.<br />

Results: We identified 62 infants comprising 32% of all admissions with Influenza A(H1N1)pdm09.<br />

The median age ± SD was 7 ± 4 months. Nineteen (31%) had pre-existing high-risk medical conditions.<br />

Complications were documented in 53% of previously healthy infants compared to 47% in high-risk<br />

infants. Mean duration of hospitalization was 4.9 days in healthy infants and 6.7 for infants with highrisk<br />

medical conditions. Bacterial pneumonia complicated 7% of previously healthy infants compared to<br />

26% with high-risk conditions (P = 0.03). Four infants (6.5%) required admission to the intensive care unit<br />

(ICU), of whom three had high risk medical condition.<br />

Conclusion: The majority of hospitalized infants with Influenza A(H1N1)pdm09 were previously healthy.<br />

Prolonged hospitalization, ICU admission and mortality were more observed in infants with high-risk<br />

medical conditions. According to the latest Advisory Committee on Immunization Practices (ACIP)<br />

recommendations, annual influenza vaccination is recommended for any child six months of age and<br />

older, particularly those with risk factors.<br />

Objective: To determine the proportion of pre-hypertension and hypertension in college students in<br />

Kuwait and their related risk factors.


<strong>December</strong> <strong>2012</strong><br />

KUWAIT MEDICAL JOURNAL 352<br />

Materials and Methods: A total of 803, randomly selected students aged 17 to 23 years (346 male, 457<br />

female) from different colleges in Kuwait, were included in the study between 2009 and 2010. Systolic and<br />

diastolic blood pressure measurements were taken by trained personnel. Pre-hypertension was defined as<br />

systolic pressure between 120 and 139 mm Hg or diastolic pressure between 80 and 89 mm Hg. Risk factor<br />

measurements that were determined, included smoking, body mass index (BMI), and family history of<br />

hypertension. Blood samples were collected and impaired glucose tolerance (IGT) and lipid profile levels<br />

were determined.<br />

Results: There were no hypotensive students. Normotensives constituted 53.5% (n = 430), pre-hypertensives<br />

formed 39.5% (n = 317), and hypertensive students comprised of 7% (n = 56). The overall proportions<br />

of hypertension and pre-hypertension were higher among male students (85.7 and 64.4%) than female<br />

students (14.3 and 35.6%), respectively. Hypertensive and pre-hypertensive students versus normotensive<br />

students had significantly higher levels of BMI-based obesity, smoking, glycated hemoglobin (HbA1c),<br />

and IGT. Also, hypertensive and pre-hypertensive, compared to normotensive students, had significantly<br />

higher proportions (21.4, 18.3, and 4.0%, respectively) of risky high-density lipoprotein (HDL) level<br />

(< 1 mg / dL), cholesterol (7.1, 3.8, and 1.4%, respectively), and triglycerides (TG) (17.9, 9.1, and 7.9%,<br />

respectively) where p was< 0.001, 0.016, and 0.051, respectively.<br />

Conclusion: Hypertensive and pre-hypertensive students showed elevated levels of lipids and BMIbased<br />

obesity more than normotensive students. TG, HDL, HbA1c, and cholesterol appeared to influence<br />

pre-hypertension.<br />

Closed Reduction and Percutaneous Cannulated Screws Fixation<br />

of Displaced Intra-Articular Calcaneus Fractures<br />

AL-Razi Orthopedic Hospital, Kuwait. E-mail: Sherifmaa@yahoo.com<br />

Background: Displaced intra-articular calcaneal fractures remain a therapeutic challenge due to fracture<br />

complexity and different treatment options. One of the adverse effects of operative treatment is secondary<br />

damage to soft tissues. To avoid soft tissue complications, several less invasive procedures have been<br />

introduced. The most frequently used minimally invasive technique is closed reduction of fracture and<br />

percutaneous cannulated screws fixation.<br />

Method: This study evaluates the medium-term outcome of a new technique of percutaneous treatment in<br />

60 cases operated in Al-Razi orthopedic hospital in Kuwait in the period from 2007 to 2009. The described<br />

technique applies the principle of closed manipulation with new reduction method using a medial<br />

subperiosteal tunnel to manipulate the fragments. The technique involves new method of distribution of<br />

screws required to fix the fracture.<br />

Results: According to the American Orthopedic Foot and Ankle Society Hind foot Score, 38.3% of all cases<br />

(22 cases) had excellent results, 41% good (25 cases), fair results in 15% (9 cases), and poor results in 5% (4<br />

cases). The overall satisfactory results (excellent and good) were 79.3%.<br />

Conclusion: The technique is suitable for most types of intra-articular fractures especially in patients with<br />

compromised soft tissues in which open reduction and internal fixation is contraindicated.

1. DIABETES<br />

What is diabetes?<br />

Diabetes is a chronic disease that occurs either<br />

when the pancreas does not produce enough insulin<br />

or when the body cannot effectively use the insulin it<br />

produces. Insulin is a hormone that regulates blood<br />

sugar. Hyperglycaemia, or raised blood sugar, is a<br />

common effect of uncontrolled diabetes and over time<br />

leads to serious damage to many of the body’s systems,<br />

especially the nerves and blood vessels.<br />

KEY FACTS<br />

• 346 million people worldwide have diabetes.<br />

• In 2004, an estimated 3.4 million people died from<br />

consequences of high blood sugar.<br />

• More than 80% of diabetes deaths occur in low- and<br />

middle-income countries.<br />

• WHO projects that diabetes deaths will double<br />

between 2005 and 2030.<br />

• Healthy diet, regular physical activity, maintaining<br />

a normal body weight and avoiding tobacco use<br />

can prevent or delay the onset of type 2 diabetes.<br />

Type 1 diabetes<br />

Type 1 diabetes (previously known as insulindependent,<br />

juvenile or childhood-onset) is<br />

characterized by deficient insulin production and<br />

requires daily administration of insulin. The cause of<br />

type 1 diabetes is not known and it is not preventable<br />

with current knowledge.<br />

Symptoms include excessive excretion of urine<br />

(polyuria), thirst (polydipsia), constant hunger, weight<br />

loss, vision changes and fatigue. These symptoms may<br />

occur suddenly.<br />

Type 2 diabetes<br />

Type 2 diabetes (formerly called non-insulindependent<br />

or adult-onset) results from the body’s<br />

ineffective use of insulin. Type 2 diabetes comprises<br />

90% of people with diabetes around the world, and is<br />

largely the result of excess body weight and physical<br />

inactivity.<br />

Symptoms may be similar to those of Type 1<br />

diabetes, but are often less marked. As a result, the<br />

disease may be diagnosed several years after onset,<br />

once complications have already arisen.<br />

Until recently, this type of diabetes was seen only in<br />

adults, but it is now also occurring in children.<br />

Gestational diabetes<br />

Gestational diabetes is hyperglycaemia with onset<br />

or first recognition during pregnancy.<br />

Symptoms of gestational diabetes are similar to<br />

Type 2 diabetes. Gestational diabetes is most often<br />

diagnosed through prenatal screening, rather than<br />

reported symptoms.<br />

Impaired glucose tolerance (IGT) and impaired<br />

fasting glycaemia (IFG)<br />

Impaired glucose tolerance (IGT) and impaired<br />

fasting glycaemia (IFG) are intermediate conditions in<br />

the transition between normality and diabetes. People<br />

with IGT or IFG are at high risk of progressing to type<br />

2 diabetes, although this is not inevitable.<br />

What are common consequences of diabetes?<br />

Over time, diabetes can damage the heart, blood<br />

vessels, eyes, kidneys, and nerves.<br />

• Diabetes increases the risk of heart disease<br />

and stroke. 50% of people with diabetes die of<br />

cardiovascular disease (primarily heart disease and<br />

stroke).<br />

• Combined with reduced blood flow, neuropathy<br />

in the feet increases the chance of foot ulcers and<br />

eventual limb amputation.<br />

WHO-Facts Sheet <strong>December</strong> <strong>2012</strong><br />

• Diabetic retinopathy is an important cause of<br />

blindness, and occurs as a result of long-term<br />

accumulated damage to the small blood vessels in<br />

the retina. After 15 years of diabetes, approximately<br />

2% of people become blind, and about 10% develop<br />

severe visual impairment.<br />

• Diabetes is among the leading causes of kidney<br />

failure. 10-20% of people with diabetes die of<br />

kidney failure.<br />

• Diabetic neuropathy is damage to the nerves as a<br />

result of diabetes, and affects up to 50% of people<br />

with diabetes. Although many different problems<br />

can occur as a result of diabetic neuropathy,<br />

common symptoms are tingling, pain, numbness,<br />

or weakness in the feet and hands.<br />

• The overall risk of dying among people with<br />

diabetes is at least double the risk of their peers<br />

without diabetes.<br />

What is the economic impact of diabetes?<br />

Diabetes and its complications have a significant<br />

economic impact on individuals, families, health<br />

systems and countries.<br />

How can the burden of diabetes be reduced?<br />

Prevention<br />

Simple lifestyle measures have been shown to be<br />

effective in preventing or delaying the onset of type<br />

2 diabetes. To help prevent type 2 diabetes and its<br />

complications, people should:<br />

• achieve and maintain healthy body weight;<br />

• be physically active – at least 30 minutes of regular,<br />

moderate-intensity activity on most days. More<br />

activity is required for weight control;<br />

• eat a healthy diet of between three and five servings<br />

of fruit and vegetables a day and reduce sugar and<br />

saturated fats intake;<br />

• avoid tobacco use – smoking increases the risk of<br />

cardiovascular diseases.<br />

Diagnosis and treatment<br />

Early diagnosis can be accomplished through<br />

relatively inexpensive blood testing.<br />

Treatment of diabetes involves lowering blood<br />

glucose and the levels of other known risk factors that<br />

damage blood vessels. Tobacco use cessation is also<br />

important to avoid complications.<br />

Interventions that are both cost saving and feasible<br />

in developing countries include:<br />

• moderate blood glucose control. People with type 1<br />

diabetes require insulin; people with type 2 diabetes<br />

can be treated with oral medication, but may also<br />

require insulin;<br />

• blood pressure control<br />

• foot care<br />

Other cost saving interventions include:<br />

• screening and treatment for retinopathy (which<br />

causes blindness)<br />

• blood lipid control (to regulate cholesterol levels)<br />

• screening for early signs of diabetes-related kidney<br />

disease.<br />

These measures should be supported by a healthy<br />

diet, regular physical activity, maintaining a normal<br />

body weight and avoiding tobacco use.<br />

2. EPILEPSY<br />

What is epilepsy?<br />

Epilepsy is a chronic disorder of the brain that affects<br />

people in every country of the world. It is characterized<br />

by recurrent seizures. Seizures are brief episodes of<br />

involuntary shaking which may involve a part of the<br />

body (partial) or the entire body (generalized) and<br />

sometimes accompanied by loss of consciousness and<br />

control of bowel or bladder function. The episodes are a<br />

result of excessive electrical discharges in a group of brain<br />

cells. Different parts of the brain can be the site of such<br />

discharges. Seizures can vary from the briefest lapses<br />

of attention or muscle jerks, to severe and prolonged<br />

convulsions. Seizures can also vary in frequency, from<br />

less than one per year to several per day.<br />

One seizure does not signal epilepsy (up to<br />

10% of people worldwide have one seizure during<br />

their lifetimes). Epilepsy is defined by two or more<br />

unprovoked seizures. Epilepsy is one of the world’s<br />

oldest recognized conditions. Fear, misunderstanding,<br />

discrimination and social stigma have surrounded<br />

epilepsy for centuries. Some of the stigma continues<br />

today in many countries and can impact the quality of<br />

life for people with the disorder and their families.<br />

KEY FACTS<br />

• Epilepsy is a chronic noncommunicable disorder of<br />

the brain that affects people of all ages<br />

• Around 50 million people worldwide have<br />

epilepsy<br />

• Nearly 80% of the people with epilepsy are found<br />

in developing regions.<br />

• Epilepsy responds to treatment about 70% of the<br />

time, yet about three fourths of affected people in<br />

developing countries do not get the treatment they<br />

need.<br />

• People with epilepsy and their families can suffer<br />

from stigma and discrimination in many parts of<br />

the world


<strong>December</strong> <strong>2012</strong><br />

KUWAIT MEDICAL JOURNAL 364<br />

Signs and symptoms<br />

Characteristics of seizures vary and depend on<br />

where in the brain the disturbance first starts, and how<br />

far it spreads. Temporary symptoms can occur, such as<br />

loss of awareness or consciousness, and disturbances<br />

of movement, sensation (including vision, hearing and<br />

taste), mood or mental function.<br />

People with seizures tend to have more physical<br />

problems (such as fractures and bruising), as well as<br />

higher rates of other diseases or psychosocial issues<br />

and conditions like anxiety and depression.<br />

Rates of disease<br />

The estimated proportion of the general population<br />

with active epilepsy (i.e. continuing seizures or the<br />

need for treatment) at a given time is between 4 - 10<br />

per 1000 people. However, some studies in developing<br />

countries suggest that the proportion is between 6 - 10<br />

per 1000. Around 50 million people in the world have<br />

epilepsy.<br />

In developed countries, annual new cases are<br />

between 40 to 70 per 100,000 people in the general<br />

population. In developing countries, this figure is<br />

often close to twice as high due to the higher risk of<br />

experiencing conditions that can lead to permanent<br />

brain damage. Close to 80% of epilepsy cases worldwide<br />

are found in developing regions. The risk of premature<br />

death in people with epilepsy is two to three times<br />

higher than it is for the general population.<br />

Causes<br />

The most common type – for six out of ten people<br />

with the disorder – is called idiopathic epilepsy and<br />

has no identifiable cause. In many cases, there is an<br />

underlying genetic basis.<br />

Epilepsy with a known cause is called secondary<br />

epilepsy, or symptomatic epilepsy. The causes of<br />

secondary (or symptomatic) epilepsy could be:<br />

• brain damage from prenatal or perinatal injuries<br />

(a loss of oxygen or trauma during birth, low birth<br />

weight)<br />

• congenital abnormalities or genetic conditions with<br />

associated brain malformations<br />

• a severe blow to the head<br />

• a stroke that starves the brain of oxygen<br />

• an infection of the brain such as meningitis,<br />

encephalitis, neurocysticercosis<br />

• certain genetic syndromes<br />

• a brain tumor<br />

Treatment<br />

Recent studies in both developed and developing<br />

countries have shown that up to 70% of newly<br />

diagnosed children and adults with epilepsy can be<br />

successfully treated (i.e. their seizures completely<br />

controlled) with anti-epileptic drugs (AEDs). After<br />

two to five years of successful treatment, drugs can be<br />

withdrawn in about 70% of children and 60% of adults<br />

without relapses.<br />

• In developing countries, three fourths of people<br />

with epilepsy may not receive the treatment they<br />

need.<br />

• About 9 out of 10 people with epilepsy in Africa go<br />

untreated.<br />

• In many low- and middle-income countries, there<br />

is low availability and AEDs are not affordable and<br />

this may act as a barrier to accessing treatment.<br />

A recent study found the average availability of<br />

generic antiepileptic medicines in the public sector<br />

to be less than 50%.<br />

• Surgical therapy might be beneficial to patients<br />

who respond poorly to drug treatments.<br />

Prevention<br />

Idiopathic epilepsy is not preventable. However,<br />

preventive measures can be applied to the known<br />

causes of secondary epilepsy.<br />

• Preventing head injury is the most effective way to<br />

prevent post-traumatic epilepsy.<br />

• Adequate perinatal care can reduce new cases of<br />

epilepsy caused by birth injury.<br />

• The use of drugs and other methods to lower the<br />

body temperature of a feverish child can reduce the<br />

chance of subsequent convulsions.<br />

• Central nervous system infections are common<br />

causes of epilepsy in tropical areas, where many<br />

developing countries are concentrated. Elimination<br />

of parasites in these environments and education<br />

on how to avoid infections would be effective ways<br />

to reduce epilepsy worldwide, for example due to<br />

neurocysticercosis.<br />

Social and ecomomic impacts<br />

Epilepsy accounts for 0.5% of the global burden of<br />

disease, a time-based measure that combines years of<br />

life lost due to premature mortality and time lived in<br />

states of less than full health. Epilepsy has significant<br />

economic implications in terms of health-care needs,<br />

premature death and lost work productivity. An Indian<br />

study calculated that the total cost per epilepsy case<br />

was US$ 3<strong>44</strong> per year (or 88% of the average income<br />

per capita). The total cost for an estimated five million<br />

cases in India was equivalent to 0.5% of gross national<br />

product.<br />

Although the social effects vary from country to<br />

country, the discrimination and social stigma that<br />

surround epilepsy worldwide are often more difficult<br />

to overcome than the seizures themselves. People<br />

with epilepsy can be targets of prejudice. The stigma<br />

of the disorder can discourage people from seeking<br />

treatment for symptoms and becoming identified with<br />

the disorder.


365<br />

WHO-Facts Sheet <strong>December</strong> <strong>2012</strong><br />

Human rights<br />

People with epilepsy experience reduced access<br />

to health and life insurance, a withholding of the<br />

opportunity to obtain a driving license, and barriers to<br />

enter particular occupations, among other limitations.<br />

In many countries, legislation reflects centuries of<br />

misunderstanding about epilepsy. For example:<br />

• In both China and India, epilepsy is commonly<br />

viewed as a reason for prohibiting or annulling<br />

marriages.<br />

• In the United Kingdom, a law forbidding people<br />

with epilepsy to marry was repealed only in 1970.<br />

• In the United States, until the 1970s, it was legal to<br />

deny people with seizures access to restaurants,<br />

theatres, recreational centres and other public<br />

buildings.<br />

Legislation based on internationally accepted<br />

human rights standards can prevent discrimination<br />

and rights violations, improve access to health care<br />

services and raise quality of life.<br />

3. MATERNAL MORTALITY<br />

Maternal mortality is unacceptably high. About<br />

800 women die from pregnancy- or childbirth-related<br />

complications around the world every day. In 2010,<br />

287,000 women died during and following pregnancy<br />

and childbirth. Almost all of these deaths occurred<br />

in low-resource settings, and most could have been<br />

prevented.<br />

KEY FACTS<br />

• Every day, approximately 800 women die from<br />

preventable causes related to pregnancy and<br />

childbirth.<br />

• 99% of all maternal deaths occur in developing<br />

countries.<br />

• Maternal mortality is higher in women living in<br />

rural areas and among poorer communities.<br />

• Young adolescents face a higher risk of<br />

complications and death as a result of pregnancy<br />

than older women.<br />

• Skilled care before, during and after childbirth can<br />

save the lives of women and newborn babies.<br />

• Between 1990 and 2010, maternal mortality<br />

worldwide dropped by almost 50%<br />

Progress towards achieving the fifth Millennium<br />

Development Goal<br />

Improving maternal health is one of the eight<br />

Millennium Development Goals (MDGs) adopted by<br />

the international community in 2000. Under MDG5,<br />

countries committed to reducing maternal mortality<br />

by three quarters between 1990 and 2015. Since 1990,<br />

maternal deaths worldwide have dropped by 47%.<br />

In sub-Saharan Africa, a number of countries have<br />

halved their levels of maternal mortality since 1990. In<br />

other regions, including Asia and North Africa, even<br />

greater headway has been made. However, between<br />

1990 and 2010, the global maternal mortality ratio (i.e.<br />

the number of maternal deaths per 100, 000 live births)<br />

declined by only 3.1% per year. This is far from the<br />

annual decline of 5.5% required to achieve MDG5.<br />

Where do maternal deaths occur?<br />

The high number of maternal deaths in some areas<br />

of the world reflects inequities in access to health<br />

services, and highlights the gap between rich and poor.<br />

Almost all maternal deaths (99%) occur in developing<br />

countries. More than half of these deaths occur in sub-<br />

Saharan Africa and almost one third occur in South<br />

Asia.<br />

The maternal mortality ratio in developing countries<br />

is 240 per 100,000 births versus 16 per 100,000 in<br />

developed countries. There are large disparities between<br />

countries, with few countries having extremely high<br />

maternal mortality ratios of 1000 or more per 100, 000 live<br />

births. There are also large disparities within countries,<br />

between people with high and low income and between<br />

people living in rural and urban areas.<br />

The risk of maternal mortality is highest for<br />

adolescent girls under 15 years old. Complications in<br />

pregnancy and childbirth are the leading cause of death<br />

among adolescent girls in most developing countries.<br />

Women in developing countries have on average<br />

many more pregnancies than women in developed<br />

countries, and their lifetime risk of death due to<br />

pregnancy is higher. A woman’s lifetime risk of<br />

maternal death – the probability that a 15 year old<br />

woman will eventually die from a maternal cause – is<br />

one in 3800 in developed countries, versus one in 150<br />

in developing countries.<br />

Why do women die?<br />

Women die as a result of complications during<br />

and following pregnancy and childbirth. Most of<br />

these complications develop during pregnancy. Other<br />

complications may exist before pregnancy but are<br />

worsened during pregnancy. The major complications<br />

that account for 80% of all maternal deaths are:<br />

• severe bleeding (mostly bleeding after childbirth)<br />

• infections (usually after childbirth)<br />

• high blood pressure during pregnancy (preeclampsia<br />

and eclampsia)<br />

• unsafe abortion.<br />

The remainder are caused by or associated with<br />

diseases such as malaria, and AIDS during pregnancy.<br />

Maternal health and newborn health are closely


<strong>December</strong> <strong>2012</strong><br />

KUWAIT MEDICAL JOURNAL 366<br />

linked. More than three million newborn babies die<br />

every year, and an additional 2.6 million babies are<br />

stillborn.<br />

How can women’s lives be saved?<br />

Most maternal deaths are avoidable, as the healthcare<br />

solutions to prevent or manage complications are<br />

well known. All women need access to antenatal care in<br />

pregnancy, skilled care during childbirth, and care and<br />

support in the weeks after childbirth. It is particularly<br />

important that all births are attended by skilled health<br />

professionals, as timely management and treatment<br />

can make the difference between life and death.<br />

Severe bleeding after birth can kill a healthy woman<br />

within two hours if she is unattended. Injecting oxytocin<br />

immediately after childbirth effectively reduces the<br />

risk of bleeding.<br />

Infection after childbirth can be eliminated, if good<br />

hygiene is practiced, and if, early signs of infection are<br />

recognized and treated in a timely manner.<br />

Pre-eclampsia should be detected and appropriately<br />

managed before the onset of convulsions (eclampsia)<br />

and other life-threatening complications. Administering<br />

drugs such as magnesium sulfate for pre-eclampsia<br />

can lower a woman’s risk of developing eclampsia.<br />

To avoid maternal deaths, it is also vital to prevent<br />

unwanted and too-early pregnancies. All women,<br />

including adolescents, need access to family planning,<br />

safe abortion services to the full extent of the law, and<br />

quality post-abortion care.<br />

Why do women not get the care they need?<br />

Poor women in remote areas are the least likely to<br />

receive adequate health care. While levels of antenatal<br />

care have increased in many parts of the world during<br />

the past decade, only 46% of women in low-income<br />

countries benefit from skilled care during childbirth.<br />

This means that millions of births are not assisted by<br />

a midwife, a doctor or a trained nurse. In high-income<br />

countries, virtually all women have at least four<br />

antenatal care visits, are attended by a skilled health<br />

worker during childbirth and receive postpartum<br />

care. In low-income countries, just over a third of<br />

all pregnant women have the recommended four<br />

antenatal care visits.<br />

Other factors that prevent women from receiving<br />

or seeking care during pregnancy and childbirth are:<br />

• poverty<br />

• distance<br />

• lack of information<br />

• inadequate services and<br />

• cultural practices.<br />

To improve maternal health, barriers that limit<br />

access to quality maternal health services must be<br />

identified and addressed at all levels of the health<br />

system.<br />

4. DIARRHEAL DISEASE<br />

Definition<br />

Diarrhea is defined as the passage of three or<br />

more loose or liquid stools per day (or more frequent<br />

passage than is normal for the individual). Frequent<br />

passing of formed stools is not Diarrhea, nor is the<br />

passing of loose, “pasty” stools by breastfed babies.<br />

Diarrhea is usually a symptom of an infection in the<br />

intestinal tract, which can be caused by a variety of<br />

bacterial, viral and parasitic <strong>org</strong>anisms. Infection is<br />

spread through contaminated food or drinking-water,<br />

or from person-to-person as a result of poor hygiene.<br />

Diarrheal disease is treatable with a solution of clean<br />

water, sugar and salt, and with zinc tablets.<br />

Diarrheal disease is the second leading cause<br />

of death in children under five years old, and is<br />

responsible for killing 1.5 million children every year.<br />

Diarrhea can last several days, and can leave the body<br />

without the water and salts that are necessary for<br />

survival. Most people who die from Diarrhea actually<br />

die from severe dehydration and fluid loss. Children<br />

who are malnourished or have impaired immunity are<br />

most at risk of life-threatening diarrhea.<br />

KEY FACTS<br />

• Diarrheal disease is the second leading cause of<br />

death in children under five years old. It is both<br />

preventable and treatable.<br />

• Diarrheal disease kills 1.5 million children every<br />

year.<br />

• Globally, there are about two billion cases of<br />

Diarrheal disease every year.<br />

• Diarrheal disease mainly affects children under<br />

two years old.<br />

• Diarrhea is a leading cause of malnutrition in<br />

children under five years old.<br />

There are three clinical types of Diarrhea:<br />

- acute watery Diarrhea – lasts several hours or<br />

days, and includes cholera;<br />

- acute bloody Diarrhea – also called dysentery;<br />

and<br />

- persistent Diarrhea – lasts 14 days or longer.<br />

Scope of Diarrheal disease<br />

Every year, there are about two billion cases of<br />

Diarrheal disease worldwide. Diarrheal disease is a<br />

leading cause of child mortality and morbidity in the<br />

world, and mostly results from contaminated food and<br />

water sources. Worldwide, around 1 billion people<br />

lack access to improved water and 2.5 billion have no


367<br />

WHO-Facts Sheet <strong>December</strong> <strong>2012</strong><br />

access to basic sanitation. Diarrhea due to infection is<br />

widespread throughout developing countries.<br />

In 2004, Diarrheal disease was the third leading<br />

cause of death in low-income countries, causing 6.9%<br />

of deaths overall. In children under five years old,<br />

Diarrheal disease is the second leading cause of death<br />

– second only to pneumonia. Out of the 1.5 million<br />

children killed by Diarrheal disease in 2004, 80% were<br />

under two years old.<br />

In developing countries, children under three years<br />

old experience on average three episodes of Diarrhea<br />

every year. Each episode deprives the child of the<br />

nutrition necessary for growth. As a result, Diarrhea<br />

is a major cause of malnutrition, and malnourished<br />

children are more likely to fall ill from Diarrhea.<br />

Dehydration<br />

The most severe threat posed by Diarrhea is<br />

dehydration. During a Diarrheal episode, water<br />

and electrolytes (sodium, chloride, potassium and<br />

bicarbonate) are lost through liquid stools, vomit,<br />

sweat, urine and breathing. Dehydration occurs when<br />

these losses are not replaced.<br />

The degree of dehydration is rated on a scale of<br />

three.<br />

• Early dehydration – no signs or symptoms.<br />

• Moderate dehydration:<br />

- thirst<br />

- restless or irritable behaviour<br />

- decreased skin elasticity<br />

- sunken eyes<br />

• Severe dehydration:<br />

- symptoms become more severe<br />

- shock, with diminished consciousness, lack of<br />

urine output, cool, moist extremities, a rapid<br />

and feeble pulse, low or undetectable blood<br />

pressure, and pale skin.<br />

Death can follow severe dehydration if body fluids<br />

and electrolytes are not replenished, either through the<br />

use of oral rehydration salts (ORS) solution, or through<br />

an intravenous drip.<br />

Causes<br />

Infection: Diarrhea is a symptom of infections<br />

caused by a host of bacterial, viral and parasitic<br />

<strong>org</strong>anisms, most of which are spread by faecescontaminated<br />

water. Infection is more common when<br />

there is a shortage of clean water for drinking, cooking<br />

and cleaning. Rotavirus and Escherichia coli are the<br />

two most common causes of Diarrhea in developing<br />

countries.<br />

Malnutrition: Children who die from Diarrhea<br />

often suffer from underlying malnutrition, which<br />

makes them more vulnerable to Diarrhea. Each<br />

Diarrheal episode, in turn, makes their malnutrition<br />

even worse. Diarrhea is a leading cause of malnutrition<br />

in children under five years old.<br />

Source: Water contaminated with human faeces,<br />

for example, from sewage, septic tanks and latrines,<br />

is of particular concern. Animal faeces also contain<br />

micro<strong>org</strong>anisms that can cause Diarrhea.<br />

Other causes: Diarrheal disease can also spread<br />

from person-to-person, aggravated by poor personal<br />

hygiene. Food is another major cause of Diarrhea<br />

when it is prepared or stored in unhygienic conditions.<br />

Water can contaminate food during irrigation. Fish<br />

and seafood from polluted water may also contribute<br />

to the disease.<br />

Prevention and treatment<br />

Key measures to prevent Diarrhea include:<br />

• access to safe drinking-water<br />

• improved sanitation<br />

• exclusive breastfeeding for the first six months of<br />

life<br />

• good personal and food hygiene<br />

• health education about how infections spread, and<br />

• rotavirus vaccination.<br />

Key measures to treat Diarrhea include the<br />

following.<br />

• Rehydration: Rehydration with intravenous fluids<br />

in case of severe dehydration or shock and/or oral<br />

rehydration salts (ORS) solution for moderate or no<br />

dehydration. ORS is a mixture of clean water, salt<br />

and sugar, which can be prepared safely at home.<br />

It costs a few cents per treatment. ORS is absorbed<br />

in the small intestine and replaces the water and<br />

electrolytes lost in the faeces.<br />

• Zinc supplements: Zinc supplements reduce the<br />

duration of a Diarrhea episode by 25% and are<br />

associated with a 30% reduction in stool volume.<br />

• Nutrient-rich foods: The vicious circle of<br />

malnutrition and Diarrhea can be broken by<br />

continuing to give nutrient-rich foods – including<br />

breast milk – during an episode, and by giving a<br />

nutritious diet – including exclusive breastfeeding<br />

for the first six months of life – to children when<br />

they are well.<br />

• Consulting a health worker, if there are signs of<br />

dehydration.
