Objective: To determine the epidemiological and clinical significance of invasive fungal infections in non-neutropenic patients in intensive care who stay longer than 10 days on the intensive care unit (ICU). Design: Prospective epidemiological multicenter study over a period of 11 months, based on strict clinical, bacteriological, serological and(More)
The number of different Legionella species is increasing at an impressive rate. In two prospective studies, one involving 110 intensive-care unit (ICU) patients with mainly nosocomial pneumonias and the other 105 patients with community-acquired pneumonias, we investigated the incidence and significance ofLegionella pneumophila and non-pneumophila(More)
The treefrog genus Boophis is one of the most species-rich endemic amphibian groups of Madagascar. It consists of species specialized to breeding in brooks (48 species) and ponds (10 species). We reconstructed the phylogeny of Boophis using 16S ribosomal DNA sequences (558 bp) from 27 species. Brook-breeders were monophyletic and probably derived from an(More)
Pulmonary alveolar proteinosis (PAP) is a rare disorder of unknown origin characterized by alveolar fillings with periodic acid-Schiff (PAS)-positive material mainly consisting of phospholipids. Mice defective in the granulocyte-macrophage colony-stimulating factor (GM-CSF) gene or the GM-CSF/interleukin (IL)-3/IL-5-receptor common beta chain (beta c)(More)
Comparisons with intraoperative findings suggest that Duplex scanning may be of value in predicting the morphology of carotid artery stenoses. Such studies, however, are based on the results obtained by experienced investigators. To clarify whether sonographic criteria can be standardized, 6 investigators from different hospitals each documented 30 carotid(More)
The mechanism of hypoprothrombinemia induced by cephalosporins containing the N-methylthiotetrazole (NMTT) side chain has been investigated in a randomized clinical, trial (pilot study) with 14 hospitalized patients (main inclusion criteria: age greater than or equal to 50 years, urinary tract infection, normal prothrombin time. Therapy groups: latamoxef (n(More)
HISTORY AND CLINICAL FINDINGS A 40-year-old man with histologically proven sarcoidosis, known for 15 years, which had involved the myocardium was hospitalized because of intractable heart failure (NYHA class IV). An implantation of an intracardiac defibrillator for ventricular arrhythmias (Lown type IVa) had preceded. On physical examination severe dyspnea(More)
