BACKGROUND Extended-spectrum beta-lactamase (ESBL)-producing Escherichia coli is an increasingly important group of community pathogens worldwide. These organisms are frequently resistant to many of the antimicrobial agents usually recommended for the treatment of infections caused by E coli, such as penicillins, cephalosporins, fluoroquinolones, and(More)
Prolonged viral excretion in immunocompromised hosts leads to long oseltamivir treatment and to the subsequent development of oseltamivir-resistant pandemic influenza virus selection. We report the selection and nasopharyngeal shedding kinetics of an oseltamivir-resistant strain in a hospitalized immunocompromised patient with prolonged influenza illness.(More)
UNLABELLED Preemptive therapy with ganciclovir has been recommended in the pediatric liver transplant strategy to avoid the development of posttransplant lymphoproliferative disorder (PTLD) from an high Epstein-Barr virus (EBV) is detected. We sought viral load to analyze the response to preemptive therapy with valganciclovir (VGC) in children with liver(More)
In June 2009, the first influenza pandemic of the twenty-first century, due to the swine origin influenza A (H1N1) 2009 virus, was declared. This study aimed to describe the epidemiological and clinical features, complications, lethality and risk factors for hospital admission of microbiologically confirmed cases of influenza A (H1N1) 2009 infection seen at(More)
OBJECTIVES Extended-spectrum beta-lactamase (ESBL)-producing Escherichia coli (ESBLEC) is an increasingly significant cause of community-acquired infection worldwide. The epidemiological features of CTX-M- and SHV-producing ESBLEC causing community-acquired infections are compared. METHODS A multicentre cohort study including all community-acquired(More)
To assess potential differences in epidemiology and management of patients admitted with influenza infection in the intensive care unit (ICU) during the first post-pandemic influenza period. Observational prospective study comparing September 2009-January 2010 with September 2010-January 2011. Variables captured: demographics, co-morbidities, physiological(More)
To investigate the potential implications (especially the implications in clinical significance and antimicrobial susceptibility) of polyclonality among rapidly growing mycobacteria, we performed random amplified polymorphic DNA analysis in 64 clinical isolates of which the clinical significance was established. Phenotypic characteristics (antimicrobial(More)
The overall incidence of spinal tuberculosis (TB) appears to be stable or declining in most European countries, but with an increasing proportion of cases in the foreign-born populations. We performed a retrospective observational study (1993-2014), including all cases of spinal TB diagnosed at a Barcelona hospital to assess the epidemiological changes.(More)
The aim of this article is to describe epidemiological and clinical data of patients with tuberculous lymphadenitis (TL) and evaluate the yield of the diagnostic techniques employed. Retrospective observational study was performed at the Vall d'Hebron University Hospital, Barcelona, Spain. All adult patients with confirmed TL (microbiologically) or probable(More)
