Evaluation of group B streptococci colonization rate in pregnant women and their newborn

Group B Streptococcus [GBS] is one of the most important bacteria in the majority of maternal and neonatal infections, such as chorioamnionitis, endometritis, bacteremia, sepsis and meningitis. During pregnancy, GBS screening is one of the recommended strategies that are recommended by center of disease control [CDC]. This study was aimed to determine the rectovaginal colonization prevalence among pregnant women, and also the rate of transmission to their offspring. Between June 2008 and April 2009, two hundred pregnant women admitted in department of Obstetrics and Gynecology [Ghaem Hospital, Mashhad, Iran] were enrolled in present study. Samples from maternal rectum and vagina as well as neonate ear and umbilical cord were taken for culture. The colonization rate for GBS in pregnant women and their neonates was around 6% and 5% respectively. All the carrier mothers were cases with premature rupture of membranes [at least 18 hours before delivery]. In terms of colonization, there was a significant correlation between mothers and newborns, and more than 80% of neonates from GBS carrier mothers were colonized by GBS

Maternal and other risk factors including bovine IgG in developing infantile colic

Infantile colic is one of the most current problems in the first few months of life. It is suggested that organic or psychologic and behavioral factors can predispose to involve this disorder. Here, we have studied the role of some maternal risk factors including bovine IgG levels in breast milk for appearing the colic in young babies. This retrospective study was performed on 50 infants as case group and 30 infants aged 3 weeks to 3 months who had normal growth and development as control group for one year in Mashad. Data was analyzed with Pearson Chi-Square and Fisher's exact tests. Most colicky infants were male [62% vs 38% female]. They were mainly symptomatic at neonatal period. In 64% of cases, it occurred in the first offspring. Infantile colic was more common in babies who delivered normally than by cesarean section and in mothers aged 20-30 years. According to our finding, there was no relationship between bovine IgG in breast milk and infantile colic. It revealed that anxious pregnant women had more colicky babies and paternal smoking seemed to develop colic in young infants. In order to reduce the occurrence of colic in infants, primigravid mothers aged 20-30 years should have a stressfree environment especially during pregnancy and no smoking exposure in this period
