The fatigue impact scale (FIS) was developed to improve our understanding of the effects of fatigue on quality of life. The FIS examines patients' perceptions of the functional limitations that fatigue has caused over the past month. FIS items reflect perceived impact on cognitive, physical, and psychosocial functioning. This study compared 145 patients(More)
4 patients with atypical pneumonia and a history of exposure to wild rabbits were found to have antibodies to Coxiella burnetii but not to the other organisms also commonly associated with atypical pneumonia. 10 (45%) of 22 snowshoe hares caught in the area where 1 of the patients snared his rabbits had antibodies to Coxiella burnetii. Q fever ought to be(More)
BACKGROUND Highly active antiretroviral therapy (HAART) is associated with improvement or resolution of several HIV-associated opportunistic infections. Although prophylaxis against disseminated Mycobacterium avium complex infection may be successfully discontinued after a favorable response to HAART, the 1999 guidelines from the U.S. Public Health(More)
Sixty-six cases of Q fever were diagnosed in people affiliated with a goat-farming co-operative in rural Newfoundland in the spring of 1999. Follow-up studies which included administration of the Short Form 36 Health Survey (SF-36) were conducted 3 and 27 months after the initial outbreak to prospectively follow the effects of acute Q fever on the quality(More)
BACKGROUND Highly active antiretroviral therapy (HAART) has been associated with liver toxicity. The role of monitoring for liver toxicity has not been well studied in resource-limited settings (RLS). OBJECTIVES To determine the background prevalence and incidence of liver injury and describe the associated signs and symptoms of acute hepatitis after(More)
Two cases of pyomyositis or bacterial abscess of striated muscle in adults are presented. One patient was initially diagnosed as having acute thrombophlebitis of the lower extremity. Computerized tomography was helpful in establishing the correct diagnosis. The other patient presented with a closed compartment syndrome following blunt trauma. Both patients(More)

Listeria monocytogenes emerged as an important foodborne pathogen in the latter part of the 20th century. Clinical syndromes caused by this microorganism include sepsis in the immunocompromised patient, meningoencephalitis in infants and adults, and febrile gastroenteritis. Focal infections at other sites are less frequent. Listeria species are commonly(More)
Fifty-one clinical isolates of Listeria monocytogenes (15 isolates from two outbreaks and 36 epidemiologically unrelated isolates) were typed by conventional serotyping, ribotyping (RT), pulsed-field gel electrophoresis (PFGE), and arbitrarily primed PCR (AP-PCR). Serotyping was unable to distinguish between related and unrelated strains of L.(More)
BACKGROUND Febrile gastroenteritis due to Listeria monocytogenes (LM) has been primarily described in foodborne outbreaks. We decided to determine the incidence of sporadic, febrile gastroenteritis due to LM in a large, well-defined North American population over a 2-year period and to compare these cases to sporadic cases of Campylobacter and Salmonella(More)
