[Evaluation of 6 years of group B streptococcus (GBS) screening in near-term pregnant women].

Streptococcus agalactiae (GBS) is a significant cause of morbidity and mortality among newborns. Colonization frequently occurs in pregnant women, nearly all international recommendations suggest that all pregnant women must be screened for vaginal colonization at 34 to 37 weeks of gestation. The microbiological diagnostic modalities used to combat GBS had to be accurate and in short time frame.

[Is there a change in ecology of Candida species incriminated in fungemia? A 7 years study at Foch Hospital].

Some Candidemia studies have documented changes in epidemiology of Candida species and some species were reported as emerging species. We conducted a study over a 6 years period and until 2005 we do not noticed any change in epidemiology of Candida even if Candida albicans still the most common species followed by Candida glabrata. No increase of candidemia was observed from 2000 to 2005 and we observed a decrease during the year 2006, this fact have to be confirm and may be related to other data: reinforcement of hygienic measures in our hospital, changes in treatment or preemptive treatment of yeasts and fungi with new azoles or candines molecules.

Severe prekallikrein deficiencies due to homozygous C529Y mutations.

Two consecutive severe prekallikrein deficiencies were investigated. The first was identified in a 63-year-old patient admitted for ischemic stroke. The second deficiency was identified in a 38-year-old patient admitted for a second-trimester pregnancy loss.

[Uncomplicated urinary tract infections, what about fosfomycin and nitrofurantoin in 2006?].

Since 2000 to 2005 we assessed the prevalence of antimicrobial resistance among uropathogens causing acute uncomplicated urinary tract infections (UTI). A total of 19 618 bacteria were studied, fosfomycin, fluoroquinolones, nitrofurantoin were in vitro the most potent drugs with more than 80% of susceptibility. If we compare year 2000 to 2005 we observed a significant decrease of susceptibility for fluoroquinolones.

Prothrombin Suresnes: a case of homozygous F299V mutation responsible for hypodysprothrombinemia.

A patient with a severe prothrombin deficiency and a hemorrhagic diathesis was found to have positive cross-reactive material in plasma and a homozygous F299V mutation (F7V in the A chain). This mutation reinforces the previous conclusion that the A chain affects the geometry of the catalytic triad. Marked prolongation of the Taipan venom and Russell venom clotting times also demonstrated a defective activation mechanism and a defective interaction with factor Xa.
