P OSTER<br />
A BSTRACTS<br />
then awoke spontaneously and continued to wretch. His mental status<br />
was at baseline and he reported feeling well as he was taken to the ED<br />
for further evaluation. EKG was notable for first degree AV block<br />
(PR interval 224ms, unchanged from prior). Results of a CBC, serum<br />
chemistries, Echocardiogram (done one month prior), and abdominal<br />
CT scan were normal. He was able to eat and drink and had no further<br />
syncopal episodes during 8 hours of observation in the ED. Our<br />
clinical impression was reflex mediated vasovagal syncope secondary<br />
to significant upper gastrointestinal distress. Despite this benign explanation<br />
of his syncope, the ED physician admitted him to a telemetry<br />
bed. Hours later he displayed multiple episodes of complete heart<br />
block (CHB), with one episode resulting in loss of consciousness followed<br />
by vomiting.A temporary pacing wire was placed followed by a<br />
permanent pacemaker the next day. He experienced complete resolution<br />
of his GI symptoms following pacemaker implantation.<br />
Conclusion: Current practice guidelines emphasize the preeminence<br />
of an accurate history in determining the etiology of syncope.<br />
This patient’s atypical presentation of CHB mimicked reflex mediated<br />
vasovagal syncope. His age and remote history of MI led to his<br />
admission, though it seems likely that many physicians would have<br />
discharged this patient. This case demonstrates the importance of<br />
maintaining a high index of suspicion for atypical presentations of arrhythmic<br />
syncope in very elderly patients with cardiac risk factors.<br />

A fatal case of treatment resistant C. difficile colitis.<br />

Introduction: C.diff colitis is frequently associated with previous<br />
antibiotic use especially in the elderly population and those with recent<br />
exposure to hospitals, nursing homes and daycare centers. The<br />
“National Prevalence Study of C.Diff in U.S. Healthcare Facilities”<br />
indicates that 13 out of every 1,000 inpatients were either infected or<br />
colonized with C.Diff. Mortality rate as high as 25% in elderly patients<br />
who are frail and immuno-compromised.<br />
Recurrence occurs in approximately 25 percent of cases. Oral<br />
vancomycin is the preferred therapy for severe or refractory cases.<br />
Combination of oral vancomycin and intravenous metronidazole for<br />
patients of C. diff with ileus is shown to be very effective. Efficacy of<br />
this treatment in geriatric population is still questionable.<br />
We present a treatment resistant case of C.diff colitis.<br />
Case Description: Ms L was a 95 year old female with a history<br />
of dementia and recent appendectomy who presented with C.diff colitis<br />
to the hospital. Her colitis resolved after 10 days course of<br />
Metronidazole.<br />
Approximately 4 weeks later Ms. L developed watery diarrhea,<br />
five to six times a day associated with weight loss. There were no<br />
symptoms of nausea, vomiting, abdominal pain, fever, chills or rash.<br />
Upon arrival in ER, she was thermodynamically stable, Normal<br />
physical exam with leukocytosis of 16. Patient was admitted and<br />
Metronidazole restarted.<br />
Stool for C.diff toxin was positive. Within 48 hours, her condition<br />
deteriorated. WBC rose from 16 to 50 and progressed to septic shock.<br />
Ms L was transferred to MICU and aggressive intravenous fluid therapy<br />
with vasopressors and oral vancomycin was added to the regimen.<br />
Subsequently she developed diffuse abdominal tenderness.<br />
WBC further increased to 112 with lactic acidosis of 11. Despite the<br />
classic presentation of C.Diff, leukocytosis of 112 prompted an evaluation<br />
for acute leukemia, and a flow cytometry was done which was<br />
normal.<br />
CAT scan of the abdomen revealed diffuse pseudomembranous<br />
colitis; developed multiorgan failure, ARDS and deceased within 96<br />
hours of admission.<br />
Conclusion:<br />
C. diff colitis is associated with significant mortality in the geriatrics<br />
patients. Extensive leukocytosis is associated with poor prognosis.<br />
Decreased immunity and multiple co morbidities are responsible<br />
for this increased incidence in the elderly population. The clinical syndrome<br />
of chronic C. diff and the best treatment options in this population<br />
group needs to be further investigated.<br />

BACKGROUND: The prevalence of glucose intolerance and<br />
diabetes in HIV+ patients has increased dramatically following the<br />
widespread use of highly active antiretroviral therapy and the improved<br />
survival rate in this population. The risk is further exacerbated<br />
as this population ages. Although it is known that HIV+ patients<br />
are at increased risk of frailty, little is known regarding the<br />
impact of diabetes on physical function in HIV+ older adults (HOA).<br />
PURPOSE: To explore the nature of functional impairment in HOA<br />
with glucose intolerance status as measured by having diabetes.<br />
METHODS: Twenty HOA (mean age=60 y; 30% female) participated<br />
in a case-control study at an urban HIV clinic. Ten HOA with<br />
diabetes were matched to ten HOA controls without diabetes on age,<br />
gender and BMI. Subjective and objective measures of functional status<br />
were evaluated using the Physical Performance Test (PPT),<br />
graded treadmill test, isokinetic dynamometer, gait speed, balance<br />
and functional status questionnaires (FSQ). Body composition was<br />
evaluated using DXA. Muscle quality was evaluated by determining<br />
the ratio of leg strength to leg lean mass. RESULTS: The two groups<br />
were comparable in duration of HIV, CD4 count and viral load. Compared<br />
with matched controls, the case patients had lower scores in<br />
PPT, peak aerobic power, and FSQ (p
