    ABSTRACT: Candida species is the fourth most common cause of bloodstream infection and is the leading cause of invasive fungal infection among hospitalized patients. Acute disseminated candidiasis remains a life-threatening disease that now occurs mainly in intensive care units hospitalized patients. Delay in treatment of Candida bloodstream infections could be minimized by the development of more rapid and sensitive diagnostic techniques for the identification of Candida bloodstream infections. Current guidelines for the management of invasive candidiasis recommend fluconazole or an echinocandin as the primary therapeutic option. The optimal choice of the antifungal agent should depend on local epidemiology, prior antifungal therapy and patient's characteristics.

    ABSTRACT: Candida parapsilosis is a normal saprophyte of the skin, characterized by their affinity for catheters. This species has, in vitro, a level of sensitivity against the echinocandins, significantly lower than that observed with other Candida species. Recently, new species: Candida orthopsilosis and Candida metapsilosis, phenotypically identical to C. parapislosis, have been identified by molecular biology. From 2003 to 2007, in the Cochin hospital, the proportion of C. parapsilosis among non-albicans species isolated from blood cultures increased from 17 (3/18) to 38% (5/13). To understand the reasons for this emergence, we retrospectively characterized isolates, conducted a case-control and researched a link between the emergence and introduction of caspofungin in our hospital. We analysed data from 26 patients who had candidemia with C. parapsilosis. Genotypic analysis of isolates has not identified the new species C. orthopsilosis and C. metapsilosis. The case-control study showed a broad-spectrum antibiotics was significantly more frequent for candidemia with C. parapsilosis compared to C. albicans (52 versus 26%, P=0.04) as a previous treatment with caspofungin (11 versus 0%, P=0.04). The introduction of caspofungin is contemporary with the emergence of candidemia with C. parapsilosis with a tendency to be related to its level of consumption in the ICU. Our results should encourage biologists to closely monitor the frequency and level of sensitivity of strains of C. parapsilosis isolated in hospital.

    ABSTRACT: Objective The incidence of extended-spectrum beta-lactamase-producing enterobacteria (ESBLE) has regularly increased over the last few years. However, little is known about epidemiology of ESBLE carriers in France. The objective of this study was to determine the ESBLE carriers or infected patients profile, identified within 48hours following hospital admission.

    ABSTRACT: The incidence of extended-spectrum beta-lactamase-producing enterobacteria (ESBLE) has regularly increased over the last few years. However, little is known about epidemiology of ESBLE carriers in France. The objective of this study was to determine the ESBLE carriers or infected patients profile, identified within 48 hours following hospital admission. This retrospective study included all patients admitted in 2006 and 2007 at the Necker-Enfants-Malades (NEM) teaching hospital, carrying or infected with ESBLE isolated within 48 hours following admission. The pediatric and adult populations were compared. There was no significant difference between pediatric and adult populations. Escherichia coli and Klebsiella pneumoniae were the two main species isolated, accounting respectively for 59.6 and 21.1 % of the 114 isolated strains. Among the 114 analyzed files, 24 patients (21 %) were known to be EBLSE carriers, 37 (32 %) were transferred from another hospital, including 16 from another country. Concerning the 54 (47 %) other patients, five (4 %) came from a country with high prevalence, and 44 (39 %) were treated for a chronic illness. Only five patients (4 %) carrying ESBLE did not have any usual risk factor for multidrug resistance (MDR) bacterial carriage. In our study, 4 % of patients carrying ESBLE admitted had no usual risk factor for MDR bacteria. Targeted screening of previous carriers, patients with chronic illness, transferred patients, or patients coming from country with high prevalence, would help to limit the spread of ESBLE.

    ABSTRACT: IntroductionVancomycin is still the cornerstone of antibiotic therapy for patients with suspected or proven invasive methicillin resistant Staphylococcus aureus infections. However, clinical and pharmacodynamic studies underline that appropriate doses depend on the infection site, the patient's weight, his renal function, and the bacterial susceptibility.

    ABSTRACT: Vancomycin is still the cornerstone of antibiotic therapy for patients with suspected or proven invasive methicillin resistant Staphylococcus aureus infections. However, clinical and pharmacodynamic studies underline that appropriate doses depend on the infection site, the patient's weight, his renal function, and the bacterial susceptibility. In this prospective study made in a Paris teaching hospital, our two goals were to describe the modalities of infusion and serum concentration obtained during therapy, in our pediatrics and adults population. In our hospital, vancomycin was administered every eight hours in 83 % (97/102) of the cases and the doses used were 30 mg/kg per day in 67 % of cases (68/102). Serum trough levels reached 15 mcg/ml and 20 mcg/ml in 36 % and 18 % of cases respectively. Moreover, despite adequate doses, trough levels of 15 mcg/ml were obtained in only 40 % of cases. Vancomycin infusion use could be optimized, by defining optimal serum concentrations and monitoring made by a mobile team of infectious diseases specialists.

    ABSTRACT: A 59-year-old patient underwent laparoscopic radical prostatectomy (LRP) in our department. After surgery, he had an extensive cellulitis of the right flank develop. Urine, drainage effluent, and blood cultures were all positive for Escherichia coli. Prolonged broad spectrum antibiotherapy allowed progressive resolution of the cellulitis. This case shows that severe cellulitis can occur after LRP. Urinary tract infection and vesicourethral anastomotic leakage may contribute to this complication.
