Meta AnalysisThe accuracy of the procalcitonin test for the diagnosis of neonatal sepsis: a meta-analysis.
A meta-analysis was performed to assess the accuracy of the procalcitonin (PCT) test for diagnosing neonatal sepsis. The major databases, MEDLINE, EMBASE and the Cochrane Library were searched for studies published between January 1996 and May 2009 that evaluated PCT as a diagnostic marker for neonatal sepsis and provided sufficient data to calculate sensitivity and specificity. Twenty-two studies were included in the analysis. ⋯ The PCT test showed moderate accuracy in diagnosing neonatal sepsis, regardless of differences in diagnostic criteria and time points for testing. For the diagnosis of LONS, the PCT test showed better accuracy than the CRP test. PCT is a valuable additional tool for the diagnosis of neonatal sepsis.

Nosocomial imipenem-resistant Acinetobacter baumannii infections: epidemiology and risk factors.
The incidence, clinical characteristics, risk factors, antimicrobial susceptibility, and outcomes of nosocomial imipenem-resistant A. baumannii (IRAB) infections during a 5-y period (2003-2007) were retrospectively analyzed. A total of 720 patients with 925 episodes of A. baumannii infection were included in the study. A. baumannii infections were seen mostly in intensive care units. ⋯ The most active antimicrobial agents against A. baumannii were cefoperazone-sulbactam and netilmicin. The incidence of A. baumannii infections and imipenem resistance increased during the study period. IRAB infections should be considered in patients on mechanical ventilation and haemodialysis and in patients with malignancies.
