[Results from an epidemiologic study program of meningitis/encephalitis in Berlin, I: 1 January 1992-31 March 1994].

Although four types of meningitis/encephalitis must be reported by the Federal Communicable Disease Act since 1980, the incidence of etiologically not identified cases is constant over the years. We report on the first results in 1097 patients with meningitis who were examined by microbiological methods. These examinations were free of charge for the clinics in Berlin.

[Mezlocillin concentrations in human lung tissue].

The antibiotic concentrations were determined in 28 serum samples, 24 samples of lung parenchyma and 21 samples of the skeletal muscle from 28 patients who had undergone pneumonectomy. 5 g mezlocillin had been given i. v.

[A pilot and a controlled study of the influence of ethambutol on serum urate concentration and uric acid clearance (author's transl)].

Ethambutol is said to be capable of elevating serum urate concentration. This statement was reconsidered in three investigations using strictly supervised administration of ethambutol in a single daily dose of 25 mg. per kg.

[Tobramycin Concentration in Human Lung Tissue (author's transl)].

In 27 patients it was experimentally demonstrated that after an i. m. injection of 80 mg tobramycin concentrations are obtained in human lung tissue which for about two hours are higher than the minimal inhibition concentration of most gramnegative organisms.
