Prevalance of heparin-dependent platelet-activating antibodies in preterm newborns after exposure to unfractionated heparin.

Heparin is frequently used in preterm infants to prolong the patency of intravascular catheters. The aim of this study was to evaluate the prevalence of heparin-dependent platelet-activating antibodies in newborns. A cross-section of all preterm newborn infants expected to require heparin to maintain patency of a central venous access line were enrolled.

Microbiologic surveillance using nasal cultures alone is sufficient for detection of methicillin-resistant Staphylococcus aureus isolates in neonates.

During an outbreak of methicillin-resistant Staphylococcus aureus (MRSA) in the neonatal intensive care units at two hospitals, we assessed several sites for detection of MRSA colonization. Nasal cultures found 32 of 33 MRSA-colonized patients (97%). Rectal cultures detected 29% of 24 MRSA-colonized patients identified by paired rectal and nasal samples and axillary samples found 22% of 9 MRSA-colonized patients identified by axillary samples paired with nasal swabs.
