METHODS A total 75 consecutive patients tested for HIV on the basis of clinical suspicion of the disease from July to September 1996 at the University Hospital Centre, Yaounde, Cameroon were(More)
BACKGROUND AND PURPOSE To determine the relationship between chronic Chlamydia pneumoniae infection and stroke in Cameroon.

There was no sex difference, but the incidence increased with age from 13.2% at under 20 years to 75% at 30 years and over. The mean serum cholesterol and total and unconjugated bilirubin concentrations were not(More)
BACKGROUND Cardiovascular disease is an increasingly important issue in human immunodeficiency viral (HIV)-infected individuals. There is dearth of information on the patterns of cardiovascular disease especially in sub-Saharan Africa (SSA) patients. This study reports on the clinical, biological, electrocardiographic and echocardiographic characteristics(More)
In the first phase of our study, a group of 58 patients were investigated: electromyographic abnormalities were recorded in 52%, electrocardiographic abnormalities in 48%, electroencephalographic abnormalities in 47%, spirographic abnormalities in 31%. Impairments of central nervous system occur classically in Trypanosoma gambiense infection, while cardiac(More)
OBJECTIVE To determine the mortality rate and its predictors in patients with a presumptive diagnosis of tuberculous pericarditis in sub-Saharan Africa. DESIGN Between 1 March 2004 and 31 October 2004, we enrolled 185 consecutive patients with presumed tuberculous pericarditis from 15 referral hospitals in Cameroon, Nigeria and South Africa, and observed(More)

The echocardiographic feature of multiple cystic lesions were mainly related to the left ventricle, there was thickening of the visceral pericardium, and some restriction to ventricular filling. The cysts contained anchovy sauce(More)
