A BSTRACTS<br />
Case: A 78 year-old male with history of coronary artery disease,<br />
hypertension and chronic atrial fibrillation was admitted following a<br />
fall without major injury. He presented with a two-month history of<br />
progressive muscle weakness and pain resulting in difficulty in ambulation.<br />
He underwent coronary artery bypass graft two months prior.<br />
Medications included cardizem, digoxin, warfarin, simvastatin, amiodarone.<br />
Physical examination was remarkable for generalized muscle<br />
tenderness and decreased muscle strength of 3-4/5 in all four extremities.<br />
Laboratory tests showed elevated CK of 10,280, aspartate<br />
aminotransferase of 563, alanine aminotransferase of 403, alkaline<br />
phosphatase of 99, normal renal function. Urinalysis showed large<br />
blood with 5-10 red blood cells. Simvastatin was stopped and patient<br />
was started on intravenous hydration. His CK level transiently decreased<br />
to 8,900, but on the third day it increased to 11,600. Intravenous<br />
hydration was continued and bicarbonate drip was started.<br />
Patient’s family later reported that amiodarone was just recently<br />
started after the bypass graft two months prior. Amiodarone was<br />
stopped and the patient’s clinical status steadily improved. By day<br />
seven, his CK level dropped to 700.<br />
Discussion: The severity of rhabdomyolysis ranges from asymptomatic<br />
elevations in serum muscle enzymes to life-threatening cases<br />
with extreme enzyme elevations, electrolyte imbalances and renal<br />
failure. Classic presentation includes myalgia, red to brown urine due<br />
to myoglobinuria, and elevated serum CK levels. Many drugs are<br />
known to cause rhabdomyolysis including statins, colchicine, and cocaine.<br />
Few cases of amiodarone-induced rhabdomyolysis have been<br />
reported. In this case, the patient continued showing worsening CK<br />
levels in spite of stopping the statin. His clinical status and CK level<br />
dramatically improved upon discontinuation of amiodarone. Physicians<br />
must keep in mind that amiodarone can be one of the uncommon<br />
causes of rhabdomyolysis.<br />

Introduction: Chronic subdural hygroma is common among elderly<br />
individuals. It is a lesser-known potentially reversible cause of<br />
dementia. We present a case of an elderly male with chronic subdural<br />
hygroma presenting as dementia.<br />
Case: An 81 year-old male with medical history of mild hypertension<br />
was brought in by his daughter to Geriatric clinic to establish<br />
medical care. Patient was recently seen by psychiatry and neurology<br />
due to insomnia and agitation (especially at night), started on Memantine<br />
and Donepezil for diagnosis of Dementia. Physical examination<br />
was unremarkable except for disorientation to place and time, inability<br />
to do three-item recall, and Mini-mental state examination<br />
score of 17/30. Laboratory tests were normal including thyroid functions,<br />
vitamin B12, and Syphillis IgG. CAT scan of the brain revealed<br />
chronic subdural hygroma overlying the right cerebral convexity with<br />
midline shift, moderate cerebral and cerebellar atrophy. Patient was<br />
referred to neurosurgery clinic, however patient and family refused to<br />
undergo any neurosurgical intervention. Repeat brain CAT scan<br />
showed increase in subdural hygroma with possible subacute and/or<br />
acute component, but patient had no worsening of clinical<br />
signs/symptoms on subsequent clinic follow-ups. Patient will be followed<br />
in neurosurgery, neurology and geriatric clinic with serial brain<br />
CAT scan.<br />
Discussion: Chronic subdural hygroma is a subdural collection<br />
of cerebrospinal fluid (CSF). This results from sudden decrease in<br />
pressure by ventricular shunting leading to leak of CSF from the subarachnoid<br />
space into the subdural space especially in cases with moderate<br />
to severe brain atrophy. Elderly patients are prone to develop<br />
hygromas owing to frequent falls sustaining head trauma, and significant<br />
cerebral atrophy related to old age. Large hygromas may cause<br />
secondary localized mass effects on the adjacent brain parenchyma<br />
causing neurologic symptoms. Global deficits such as disturbances of<br />
consciousness are more common than focal deficits. Brain CAT scan<br />
would show crescent-shaped extra-axial lesions. Surgical evacuation<br />
is recommended if there is evidence of moderate to severe cognitive<br />
impairment or progressive neurologic deterioration. Physicians<br />
should recognize chronic subdural hygroma as a reversible cause of<br />
dementia among the geriatric population.<br />

Actinomyces israelii - A rare cause of prosthetic joint infection in<br />
the elderly.<br />

Hospital and Medical Center, West Reading, PA.<br />
INTRODUCTION: Actinomyces prosthetic joint infections are<br />
extremely rare, described in only half a dozen case reports in medical<br />
literature. Our case describes a patient who presented with new onset<br />
prosthetic joint infection with no identifiable local or systemic source<br />
or trauma.<br />
CASE PRESENTATION: A 72 year old male with a history of<br />
left total hip replacement in 2002 presented to the hospital with a one<br />
month history of night sweats and progressively worsening pain in the<br />
left leg. He denied any fever, trauma or injury to the affected side. On<br />
physical exam, he had a temperature of 38.7 degrees Celsius and a<br />
pulse of 115 per minute. Musculoskeletal examination was significant<br />
for a tender left hip joint at the groin with limited range of motion.<br />
On laboratory work up, he had an ESR of 82mm/sec, CRP of 15<br />
mg/dL and leukocytosis of 31,300/cu mm with 90% neutrophils. CT<br />
scan of the hip revealed an attenuated fluid-filled distended region<br />
anterior to the hip prosthesis and muscular asymmetry suspicious for<br />
an abscess. Surgical arthrotomy of the left hip joint with debridement<br />
was done. On histopathology, the specimen showed granulation tissue<br />
with acute-on-chronic inflammation and grew Actinomyces israelli<br />
on cultures. He was started on ampicillin and later switched to doxycycline<br />
due to a significant allergic reaction to the former for 6 weeks.<br />
He was discharged with instructions for outpatient follow up for prosthesis<br />
removal.<br />
DISCUSSION: Actinomyces israelii, a gram positive anaerobic<br />
bacterium, causes infections involving the oral cervicofacial area,<br />
lungs and abdomen. Involvement of the musculoskeletal system is<br />
rare and attributable to adjacent soft tissue infections, occasionally to<br />
local trauma or hematogenous spread. Late infections of prosthetic<br />
joints have been described in literature as spread from an extra articular<br />
site. Diagnosis is established by bacteriological identification<br />
using sterile cultures showing characteristic appearance and sulfur<br />
granules. Penicillins are the mainstay of treatment, and use of tetracycline<br />
class has been reported in cases of penicillin allergy. A combination<br />
of medical and surgical therapy with consideration for prosthesis<br />
removal needs to be considered. Some experts recommend prolonged<br />
antibiotic courses for better results. Early recognition of this<br />
entity even in the absence of an obvious predisposing cause is required<br />
for early diagnosis and institution of therapy.<br />
