INTRODUCTION: The prevalence of maternal group-B-streptococcus (GBS) colonization and risk factors (RFs) for neonatal early-onset disease (EOD) in Europe are poorly defined. Large-scale information concerning adherence to recommendations for preventing GBS-EOD are lacking. MATERIALS AND METHODS: This was a 3-month retrospective area-based study including all regional deliveries ≥35 weeks' gestation (in 2012). The sensitivity, specificity, positive and negative predictive values, odds ratio and receiver operating characteristic (ROC) curve for intrapartum antibiotic prophylaxis (IAP) among full-term and preterm deliveries and prolonged membrane rupture (PROM) were calculated. RESULTS: Among 7133 women, 259 (3.6%) were preterm (35-36 weeks' gestation). Full-term women were 6874, and 876 (12.7%) had at least 1 RF. Most women (6495) had prenatal screening and 21.4% (1390) were GBS positive. IAP was given to 2369 (33.2%) women (preterm, n = 166; full term, n = 2203). Compared to full-term, preterm women were less likely to receive IAP when indicated (73.2% versus 90.3%, p

Down syndrome is associated with an increased susceptibility to infections due to a deficiency of both specific and nonspecific immunity. Aim: The aim of the study was to analyze the temporal trends, if any, of some variables related to the immunological status of children affected by Down syndrome. Methods: Heparinized blood samples were obtained by venipuncture in 30 children with Down syndrome, who were regularly followed in our department and analyzed for hematologic values, lymphocyte subpopulations, immunoglobulin dosage and zinc level. Results were compared with those of the normal population. Results: In the first 5 years of life, we observed a progressive decrease in the medium values of lymphocytes, CD4+ and plasma zinc levels, and an increase in CD8+, immunoglobulin A, immunoglobulin G, immunoglobulin M and natural killer, but generally without exceeding the interval of normality. Conclusions: In Down syndrome children, the immune cellular status is similar to the normal population as far as white blood cell, lymphocyte, CD4+, CD8+, natural killer and immunoglobulins are concerned. Plasma level of zinc is normal from birth until 5 years but with a temporal trend of progressive reduction. This observation supports the hypothesis that a pharmacological supplementation may be necessary in Down syndrome children only after 5 years of age.

Objective To evaluate clinical data and associated risk conditions of noncerebral systemic venous thromboembolism (VT), arterial thromboembolism (AT), and intracardiac thromboembolism (ICT) in neonates. Study design Data analysis of first systemic thromboembolism occurring in 75 live neonates (0-28 days), enrolled in the Italian Registry of Pediatric Thrombosis from neonatology centers between January 2007 and July 2013. Results Among 75 events, 41 (55%) were VT, 22 (29%) AT, and 12 (16%) ICT; males represented 65%, and 71% were preterm. In 19 (25%), thromboembolism was diagnosed on the first day of life. In this "early onset" group, prenatal-associated risk conditions (maternal/placental disease) were reported in 70% and inherited thrombophilia in 33%. Postnatal risk factors were present in 73%; infections and central vascular catheters in 56% and 54% VT, respectively, and in 67% ICT vs 27% AT ( Conclusions This report from the Registro Italiano Trombosi Infantili, although limited by representing an uncontrolled case series, can be used to develop future clinical trials on appropriate management and prevention of neonatal thrombosis, focusing on obstetrical surveillance and monitoring of critically ill neonates with vascular access. A thrombosis risk prediction rule specific for the neonatal population should be developed through prospective controlled studies.
