Gastrointestinal bleeding as the initial manifestation of a polyarteritis nodosa-associated hepatic artery aneurysm-duodenal fistula--a case report.

The authors report an unusual case of upper gastrointestinal bleeding from a hepatic artery aneurysm-duodenal fistula in a 21-year-old male. Arteriography revealed multiple visceral artery aneurysms. Biopsy of the hepatic artery aneurysm (HAA) revealed focal areas of necrosis, medial degeneration, fibrosis, and giant cells.

Heparin-associated antiplatelet antibodies increase morbidity and mortality in hemodialysis patients.

Background: Patients are frequently exposed to heparin during hemodialysis (HD) to prevent thrombosis of the extracorporeal circuit. Other groups with frequent heparin exposures have a high rate of development of heparin-associated antiplatelet antibodies (HAAb). We sought to define the prevalence of HAAb in HD patients and evaluate their effects.

A camera's view of consumer food-handling behaviors.

Objective: To compare consumer food-handling behaviors with the Fight BAC! consumer food-safety recommendations.

Design: Subjects were videotaped in their home while preparing a meal. Videotapes were coded according to Fight BAC! recommendations.

Heparin-induced thrombocytopenia: twenty-nine years later.

Objective: To determine the current frequency, types of patients, indications for testing, morbidity and mortality, and management of heparin-induced thrombocytopenia (HIT).

Methods: Between December 1998 and July 2001, the charts of 102 inpatients that tested positive for heparin-associated antiplatelet antibodies (HAAb) were reviewed. There were 33,941 inpatients, 10,348 of them having received unfractionated or low molecular weight heparins.

Abdominal aortic sarcoma: report of a case with long-term survival and review of the literature.
