Oral sildenafil was administered easily and tolerated as well as placebo and improved OI in infants with severe PPHN, which suggests that oral sildenafil may be effective in the treatment of PPHN and underscores the need for a large, controlled trial.

Oxygen is a neonatal health hazard that should be avoided in clinical practice. In this review, an international team of neonatologists and nurses assessed oxygen saturation (SpO2) targeting in preterm infants and evaluated the potential weaknesses of randomised clinical trials.ConclusionSpO2 of 85–89% can increase mortality and 91–95% can cause hyperoxia and ill effects. Neither of these ranges can be recommended, and wider intermediate targets, such as 87–94% or 88–94%, may be safer.

High PaO(2) occurs very rarely in neonates breathing supplemental oxygen when their pulse oxygen saturation values are 85% to 93%. This pulse oxygen saturation range also is infrequently associated with low PaO(2) values. Pulse oxygen saturation values of >93% are frequently associated with PaO(2) values of >80 mmHg, which may be of risk for some newborns receiving supplemental oxygen.

AimsTo determine the incidence of congenital toxoplasmosis in Colombian newborns from 19 hospital or maternal child health services from seven different cities of five natural geographic regions (Caribbean, Central, Andean, Amazonia and Eastern).Materials and MethodsWe collected 15,333 samples from umbilical cord blood between the period of March 2009 to May 2010 in 19 different hospitals and maternal-child health services from seven different cities. We applied an IgM ELISA assay (Vircell, Spain) to determine the frequency of IgM anti Toxoplasma. The results in blood cord samples were confirmed either by western blot and repeated ELISA IgM assay. In a sub-sample of 1,613 children that were negative by the anti-Toxoplasma IgM assay, the frequency of specific anti-Toxoplasma IgA by the ISAGA assay was determined. All children with positive samples by IgM, IgA, clinical diagnosis or treatment during pregnancy were recalled for confirmatory tests after day 10 of life.Results61 positive samples for specific IgM (0.39%) and 9 positives for IgA (0.5%) were found. 143 questionnaires were positive for a clinical diagnosis or treatment for toxoplasmosis during pregnancy. 109 out of the 218 children that had some of the criteria for postnatal confirmatory tests were followed. Congenital toxoplasmosis infection was confirmed in 15 children: 7 were symptomatic, and three of them died before the first month of life (20% of lethality). A significant correlation was found between a high incidence of markers for congenital toxoplasmosis and higher mean annual rainfall for the city.ConclusionsIncidence for congenital toxoplasmosis is significantly different between hospitals or maternal child health services from different cities in Colombia. Mean annual rainfall was correlated with incidence of congenital toxoplasmosis.

Maternal allopurinol/oxypurinol crosses the placenta during fetal hypoxia. In fetuses/newborns with therapeutic allopurinol/oxypurinol concentrations in cord blood, lower plasma levels of the brain injury marker protein S-100B were detected. A larger allopurinol trial in compromised fetuses at term seems warranted. The allopurinol dosage must be adjusted to achieve therapeutic fetal allopurinol/oxypurinol concentrations.

the RSV caused 1 in 3 LRTI hospitalizations in the population, with an incidence of 30.0%. This confirms a continuous circulation of RSV in Colombia varying by geographic location.

Several investigators have hypothesized that outpatient preinduction cervical ripening with nitric oxide donors such as isosorbide mononitrate (IMN) would reduce the elapsed time from hospital admission to delivery and improve women's experience of induction of labor. This double-blind randomized placebo-controlled trial investigated whether vaginal self-administration at home by woman at term would improve the process of induction of labor. The study subjects were 350 nulliparous singleton women with cephalic presentation at Ն37 weeks' gestation, requiring cervical ripening before induction of labor. The participants self-administered IMN (n ϭ 177) or placebo (n ϭ 173) vaginally at home without fetal monitoring at 48, 32, and 16 hours before the scheduled time of admission for induction of labor. The primary study outcome measures were the elapsed time interval from hospital admission to delivery and the women's experience of home treatment for cervical ripening. Maternal satisfaction was determined with a questionnaire, using a 10 point scale with 1 ϭ extremely good and 10 ϭ not at all good.There was no statistically significant difference between the 2 study groups in the admission to delivery interval; the mean difference was 1.59 hours, with a 95% confidence interval (CI) of Ϫ5.08 to 1.89, P ϭ 0.37. Compared to placebo, however, IMN was more effective in inducing a mean change in modified Bishop score from recruitment to hospital admission (mean difference: 0.65 [95% CI, 0.14-1.17, P ϭ 0.013]). With regard to maternal satisfaction, the overall experience of home treatment was positive in both groups. Women in the placebo group reported it to be marginally more positive than those in the IMN group (placebo: 3.23 vs. IMN: 3.84; the mean difference was 0.61, with a 95% CI of 0.02-1.21, P ϭ 0.043). No difference between the 2 groups was reported in either pain or anxiety levels or in the willingness to have the treatment in a subsequent pregnancy.These data show that administration of IMN at home is effective in ripening the cervix but does not shorten the admission to delivery interval or improve maternal satisfaction. The investigators conclude from these findings that IMN in this setting has limited clinical value. EDITORIAL COMMENT(The appeal of the nitric oxide donor isosorbide mononitate (IMN) is its potential to induce cervical ripening without precipitating uterine contractions and thereby obviate the need for fetal heart rate monitoring, and allow cervical ripening to be conducted on an outpatient ba-OBSTETRICS Volume 64, Number 11 OBSTETRICAL AND GYNECOLOGICAL SURVEY ABSTRACT This investigation was conducted as part of the Mother-Infant Rapid Intervention at Delivery (MIRIAD) study, a prospective, multicenter trial assessing routine rapid human immunodeficiency virus (HIV) screening of pregnant women in inpatient and outpatient settings.
