CONTEXT The spread of drug-resistant Streptococcus pneumoniae in the community is a public health problem in developed and developing nations, but whether antibiotic use is responsible for the increase in drug resistance is not known. OBJECTIVE To analyze the relationship between penicillin-resistant S pneumoniae (PRSp) pharyngeal carriage and(More)
The antimicrobial resistance of Streptococcus pneumoniae was surveyed in 1970-1990 at Saint Joseph and Broussais hospitals in Paris (3,279 isolates) and in 1984-1990 at the National Reference Center for Pneumococci (NRCP) in Créteil (8,128 isolates). All isolates were tested for susceptibility and serotyped. At St. Joseph and Broussais hospitals, the rate(More)
The chromosomal genotypes of 277 isolates of 16 serotypes of Streptococcus agalactiae were characterized by analysis of electrophoretically demonstrable allele profiles at 12 metabolic enzyme loci. The collection comprised the type strain and 276 strains recovered from French symptomatic and asymptomatic subjects. Sixty-one distinctive electrophoretic types(More)
The aim of the study was to define criteria for left ventricular pacing in dilated cardiomyopathy (DCM) using an echocardiographic evaluation of interventricular electromechanical delay (IMD) and a correlation of IMD to QRS duration. Standard 12-lead ECG and echocardiography with pulsed Doppler tissue imaging (DTI) were recorded in 35 DCM patients (mean age(More)
RATIONALE AND OBJECTIVES Cardiac magnetic resonance imaging (MRI) has been shown to be a robust and noninvasive method to assess left ventricular (LV) cardiac function. This study sought to assess volumes and mass calculated with MRI using fast techniques for acquisition and postprocessing, and to compare results in terms of cost-effectiveness with those of(More)
Right ventricular (RV) dysfunction is a predictor of poor outcome in patients with heart disease. Conventional imaging modalities fail to assess RV volumes accurately. We sought to assess the accuracy and reproducibility of routine breath-hold gradient echo magnetic resonance imaging (MRI)-derived RV mass, volumes and function. We assessed (1) The accuracy(More)
A multicentre, open-label, randomized study was performed in 501 out-patients with acute otitis media, aged 6-36 months, to study the impact of treatment with either cefixime suspension 8 mg/kg/day bd or co-amoxiclav suspension 80 mg/kg/day tds for 10 days on nasopharyngeal carriage of Streptococcus pneumoniae and Haemophilus influenzae. Of 426 patients(More)
OBJECTIVE To compare the efficacy and the safety of a single intramuscular dose of ceftriaxone, 50 mg/kg, vs. a 10-day course of amoxicillin/clavulanate (amox/clav) therapy, 80 mg/kg/day of amoxicillin: 10 mg/kg/day of clavulanate in three divided doses, in children with acute otitis media (AOM) and to evaluate the changes in nasopharyngeal flora after(More)
One hundred and eleven strains of Streptococcus agalactiae isolated from vaginas of asymptomatic women were characterized by determination of restriction length polymorphism profiles of rDNA regions (rDNA RFLP patterns) and serotyping. Thirty-five different PstI rDNA RFLP patterns were identified. Half of the strains fell into only seven of these 35 groups.(More)
We evaluated the in vitro killing activities of ceftriaxone, imipenem, vancomycin, gentamicin, fosfomycin, and rifampin, alone and in combination, against 26 Streptococcus pneumoniae strains (penicillin G MICs, > 0.125 to 2 micrograms/ml) isolated from the cerebrospinal fluid of children with meningitis. The antibiotics were tested at clinically achievable(More)
