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 />

G. Gulati, S. Gulati, D. Powell. Internal Medicine, The Reading<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 />

Confusion, ataxia and psychosis - amphetamine toxicity in the<br />

elderly.<br />

G. Gulati, S. Gulati. Internal Medicine, The Reading Hospital and<br />

Medical Center, West Reading, PA.<br />

of emergency visits in 73,400 patients per year in the United States.<br />

Classic presentations include psychosis, agitation and sympathomimetic<br />

signs.<br />
