[Staphylococcus aureus endocarditis in Denmark 1982-1991. Clinical picture, complications and antibiotic therapy in non-drug addicts].

The central S. aureus surveillance in Denmark made it possible to analyze the clinical features of S. aureus endocarditis in a nation-wide population of non-drug addicts.

Clinical features of Staphylococcus aureus endocarditis: a 10-year experience in Denmark.

Background: Both morbidity and mortality resulting from Staphylococcus aureus endocarditis are known to be high, and the incidence of this disease seems to increase. The Statens Serum Institut, Copenhagen, Denmark, made it possible for us to analyze the clinical features of S aureus endocarditis in a nation-wide population of non-drug addicts.

Methods: Almost all Danish cases of bacteremia due to S aureus are reported to the Staphylococcus laboratory, Statens Serum Institut.

Opportunistic screening for Chlamydia trachomatis cervicitis: the value of cytobrush specimens for detection by PCR compared with cell culture.

Unlabelled: Endocervical sampling for microbiological and pathological screening is laborious and expensive due to different sampling devices and techniques. The purpose of this study was to examine if the routine procedure could be simplified by using a cytobrush for concurrent cytology and sampling for Chlamydia trachomatis detection using the PCR method or cell culture. As a sampling device control we used a conventional rayon swab.
