Multicenter Study Observational StudyRisk Factors for Colistin-Associated Acute Kidney Injury: A Multicenter Study from Turkey.
The aim of this study was to investigate the incidence of acute kidney injury (AKI) and risk factors due to colistin use in patients infected with multidrug-resistant pathogens. This multicenter, retrospective, observational study was conducted in Turkey, at 5 different research and university hospitals. Cox regression analyses were performed, to determine independent predictors of AKI. ⋯ Concomitant use of loop diuretics, baseline creatinine level, and CMS dosage were independently associated with AKI. According to our results, patients with higher baseline creatinine levels, or patients who had to use concomitant loop diuretics may need to be monitored more closely, and dose adjustment should be done promptly. More comprehensive studies are, however, still needed to evaluate the efficacy of low-dose colistin since higher doses tend to increase the risk of AKI.

What We Have Learned from the Influenza A pH1N1 2009/10 Pandemic: High Clinical Impact of Human Metapneumovirus and Respiratory Syncytial Virus in Hospitalized Pediatric Patients.
The influenza pandemic in 2009/2010 shifted public awareness to respiratory tract infections caused by the influenza virus. A prospective study was conducted during the influenza pandemic from November 2009 through April 2010 to determine the causative pathogens and clinical symptoms present in all children and adolescents admitted to the University Children's Hospital, Duesseldorf, Germany, with signs and symptoms of respiratory tract infection. A total of 272 children and adolescents were admitted with symptoms of acute respiratory tract infection (ARI) or influenza-like illness. ⋯ During the pandemic and early post-pandemic phase the clinical impact of other respiratory viruses, such as HMPV and RSV, led to a higher clinical disease burden than pH1N1. Consequently, HMPV testing should be performed as routinely as RSV testing in patients hospitalized for ARI. Even while preparing for pandemics, the awareness of other respiratory viruses must be maintained.

A Epidemiological Investigation of a Nosocomial Outbreak of Multidrug-Resistant Acinetobacter baumannii in a Critical Care Center in Japan, 2011-2012.
In 2011, a multidrug-resistant Acinetobacter baumannii (MDRAB) outbreak occurred at a Japanese critical care center (CCC) in a tertiary care hospital. Multidrug-resistance in Japan is defined as resistance to the antimicrobials amikacin, carbapenem, and fluoroquinolone. We conducted a retrospective epidemiological investigation of this outbreak to identify the risk factors for MDRAB respiratory tract acquisition in this hospital. ⋯ Pulsed-field gel electrophoresis analysis and multilocus sequence typing using MDRAB isolates suggested a clonal dissemination of MDRAB strains with sequence type 74 occurred primarily among patients admitted to the CCC. From April 16, 2012, a decreased isolation rate of MDRAB in the hospital occurred after the implementation of the following infection control measures: closing the emergency room, discontinuing admission to the CCC, isolating patients with MDRAB colonization or infection to single room status, and conducting environmental cleaning. No MDRAB cases were detected between March 23 and April 20, 2012.
