Vancomycin-resistant Enterococcus outbreak in a neonatal intensive care unit: epidemiology, molecular analysis and risk factors.

Background: Vancomycin-resistant Enterococcus faecium (VRE) may cause outbreaks in neonatal intensive care units (NICU). We describe a biphasic VRE outbreak and identify risk factors for VRE acquisition.

Methods: After the occurrence of 2 cases of VRE infections in a 44-bed NICU, a bundle of interventions was implemented that included active surveillance cultures for VRE, enhanced infection control measures, and audits on antimicrobial use, from June to December 2008.

Hydrothorax as a sole manifestation of congenital parvovirus B19 infection.

We present a case of congenital parvovirus B19 infection in a term neonate manifested with isolated massive hydrothorax and mild anemia. Parvovirus B19 DNA was detected in maternal and neonatal blood as well as in pleural fluid despite lack of suggestive serology.
