September 14, 2005

Four days after having been given cefuroxime for sinusitis, a 49-year-old woman experienced abdominal cramping, diarrhea, fever (temperature of 39.4°C [103°F]), and nausea. These problems persisted for 1 week, at which time the patient arrived at the emergency department. She had no recent history of travel, ingestion of undercooked food, or exposure to anyone with similar digestive problems.

Complications of Diabetes Mellitus: Right-Sided Endocarditis in a Diabetic Patient

November 02, 2004

High-grade fever, chills, fatigue, malaise, and anorexia developed in a 35-year-old man following subclavian catheterization because of chronic renal failure of unknown cause. The patient, who had long-standing diabetes mellitus, was admitted to the ICU with the diagnosis of possible sepsis. The next day, he was found to have a grade 2/6 systolic murmur compatible with tricuspid regurgitation. This was confirmed when a 4-chamber echocardiogram (A) revealed a large single piece of vegetation (2 arrows) lying on the tricuspid valve, flapping in and out of the right ventricle. In a 2-dimensional echocardiogram of the right atrium and right ventricle (B), 3 arrows point to the vegetation. (RV, right ventricle; LV, left ventricle; RA, right atrium; LA, left atrium; TV, tricuspid valve.)
