[Experience feed back committee in radiotherapy (CREx): a compulsory tool for security management evaluation at two years].

After working on treatment organisation in radiotherapy (bonne pratiques organisationnelles en radiothérapie - action pilote MEAH 2003), the development of a security policy has become crucial. With the help of Air France Consulting and the MEAH, three cancer centers in Angers, Lille and Villejuif worked together on the implantation of experience feed back committees (CREx) dedicated to the registration, analysis and correction of precursor events. After two years, we report the centre Oscar-Lambret experience in Lille and try to get the recommendations for generalisation of the process.

Bordetella bronchoseptica pneumonia with shock in an immunocompetent patient.

Bordetella bronchoseptica is a rarely reported cause of human infection, but is a common respiratory tract commensal of mammals. Human infection with B. bronchoseptica is almost always associated with severe underlying disease and contact with an appropriate animal reservoir.

In vitro interactions between different beta-lactam antibiotics and fosfomycin against bloodstream isolates of enterococci.

The effects of 16 different beta-lactam-fosfomycin combinations against 50 bloodstream enterococci were compared by a disk diffusion technique. Cefotaxime exhibited the best interaction. By checkerboard studies, the cefotaxime-fosfomycin combination provided a synergistic bacteriostatic effect against 45 of the 50 isolates (MIC of cefotaxime at which 90% of the isolates were inhibited, >2,048 micrograms/ml; MIC of fosfomycin at which 90% of the isolates were inhibited, 128 micrograms/ml; mean of fractional inhibitory concentration indexes, 0.

Evaluation of the Epsilometer test (E test) for testing the susceptibility of coagulase-negative staphylococci to teicoplanin.

The antimicrobial susceptibilities of 118 clinical isolates of coagulase-negative staphylococci to teicoplanin were determined by disc diffusion and the Epsilometer test (E test) and the results were compared with the MICs determined by the agar dilution method of the National Committee for Clinical Laboratory Standards (NCCLS). There was a poor correlation of r = 0.5 between the zone diameters of inhibition and agar dilution MICs and 10 and four of the 11 isolates for which the MICs were > or = 32 mg/L were misclassified as susceptible by the disc test after applying the interpretative criteria of the NCCLS and the Comité de l'Antibiogramme de la Société Française de Microbiologie (CASFM), respectively.

Comparison of different beta-lactam-glycopeptide-gentamicin combinations for an experimental endocarditis caused by a highly beta-lactam-resistant and highly glycopeptide-resistant isolate of Enterococcus faecium.

A synergistic bactericidal effect between penicillin, vancomycin, and gentamicin has been described against enterococci highly resistant to beta-lactams and glycopeptides. Since such a synergy was also observed in vitro between ceftriaxone, teicoplanin, and gentamicin against Enterococcus faecium 70/90, the efficacy of different combinations including penicillin or ceftriaxone, vancomycin or teicoplanin, and gentamicin was compared in vivo in experimental endocarditis. In vitro, all four triple combinations provided a bactericidal effect.

Activation of G-proteins by receptor-stimulated nucleoside diphosphate kinase in Dictyostelium.

Recently, interest in the enzyme nucleoside diphosphate kinase (EC2.7.4.

[Two cases of FSH secreting adenomas (author's transl)].

The authors report two cases of FSH secreting adenomas in men and attempt to draw out some features of these very uncommon pituitary tumors. Absence of gynecomastia is emphasized. Diagnosis proceeds from systematic radio-immunoassay of pituitary hormones.
