Influence of topical iodine-containing antiseptics used during delivery on recall rate of congenital hypothyroidism screening program.

Background: The proportion of newborns recalled during neonatal screening programs for congenital hypothyroidism (CH) varies substantially by country and may be higher in settings where povodine iodine (PVP-I) is used during delivery. We assessed this hypothesis by substituting PVP-I for chlorhexidine (CHL) and evaluated the reduction in the recall rate of the Irainian newborn screening program.

Methods: This study investigated 2282 neonates of mothers admitted to a local hospital for delivery between December 2012 and October 2013.

Multiple correlations between cord blood leptin concentration and indices of neonatal growth.

Background And Aims: The discovery of a role for leptin in controlling fetal and neonatal growth suggests a fetal origin of some adult chronic diseases and has stimulated research into the mechanisms of action of leptin early in life. The aim of this study was to determine umbilical cord blood leptin levels and to evaluate their association with newborn growth indices.

Methods: Two hundred healthy newborns (89 males, 110 females, and one of undetermined gender; gestational ages ranging from 34-43 weeks) and their healthy mothers were enrolled in this study conducted at Moovsavi Hospital in Zanjan, Iran.
