Hepatic abscess caused by Brucella US, CT and MRI findings: case report and review of the literature.

The authors describe the findings detected by ultrasonography (US), computed tomography (CT) and magnetic resonance imaging (MRI) in a 42-year-old patient with a hepatic abscess due to brucellosis. This localization by Brucella (hepatic brucelloma) is quite rare and very often is asymptomatic. A review of the medical literature shows only 40 cases of an hepatic abscess due to brucellosis.

Seasonal variation in cryptogenic and noncryptogenic hemoptysis hospitalizations in France.

Study Objective: To determine the potential role of seasonality in hospitalizations for cryptogenic and noncryptogenic hemoptysis in the French population.

Design: Retrospective analysis of hospital discharge data from a National Register.

Setting: All 29 French university hospitals, between July 1, 1994, and June 30, 1997.

Seasonal variation in chronic heart failure hospitalizations and mortality in France.

Background: Circannual variation in blood pressure and in the incidence of acute myocardial infarction is well known but has not been investigated in chronic heart failure. This report describes and compares the seasonal variation of chronic heart failure hospitalizations and mortality in the French population.

Methods And Results: All deaths that occurred among French adults over the period 1992 to 1996 (n=138 602) and all discharges by adults in French public hospitals for chronic heart failure over the period 1995 to 1997 (n=324 013) were examined retrospectively.
