DESIGN AND SETTING A prospective multicenter study was conducted in the emergency departments of 3 teaching hospitals. PARTICIPANTS AND METHODS(More)
PURPOSE To assess the frequency of de-escalation in inpatients treated for community-acquired urinary tract infection and the frequency of conditions legitimating not de-escalating therapy. METHODS A retrospective study of inpatients (age >15 years) at a large academic hospital who were empirically treated for urinary tract infections due to Escherichia(More)
Linezolid is the first drug issued from the oxazolidinones, a novel class of antimicrobial agents with potent activity against gram-positive pathogens. A rabbit endocarditis model was used to compare the in vivo activities of different linezolid regimens mimicking intermittent dosing of 10 mg/kg of body weight every 12 h for 5 days or continuous(More)
Pneumocystis jirovecii pneumonia (PCP) is emerging in HIV-negative patients, for whom the prognosis is significantly worse than in HIV-infected patients and risk factors are poorly characterized. We performed an observational, multi-centre, prospective study of 56 consecutive cases of documented PCP in HIV-negative patients, and found that: (1) the main(More)
BACKGROUND microbiologic data are lacking regarding pediatric community-acquired peritonitis (CAP). METHODS we conducted a 2-year retrospective single center study. Consecutive children undergoing CAP surgery were included. Microbiology and antimicrobial susceptibility of peritoneal isolates were analyzed. RESULTS a total of 70 children from 3 months to(More)
The aim of this study was to compare ceftolozane with ceftazidime, piperacillin/tazobactam (TZP) and imipenem in an experimental rabbit model of Pseudomonas aeruginosa pneumonia. Efficacy was assessed following 2 days of treatment by total colony counts in different tissues (lung, spleen and blood culture). Mean ± standard deviation pulmonary bacterial(More)
The combination of quinupristin-dalfopristin (Q-D) and gentamicin was tested against two strains of gentamicin- and dalfopristin-susceptible methicillin-resistant Staphylococcus aureus (MRSA). One strain was susceptible to macrolides, lincosamides, and streptogramin B type antibiotics (MLS(B)), and the other was constitutively resistant to these antibiotics(More)
Despite the relative high frequency of Candida bloodstream infection, Candida endocarditis is a rare entity. We report seven cases, which occurred during a period of 1 year in western France. Six cases were because of Candida albicans, and one pacemaker endocarditis was because of Candida parapsilosis. All patients were men and presented risk factors for(More)
