Objective Evaluate the association between spontaneous active labor duration utilizing contemporary labor curves and risk of adverse outcomes. Materials and Methods This is a retrospective cohort study from January 2012 to January 2015. Subjects were nulliparous, 18 to 44 years, with a cephalic, singleton ≥37 weeks in spontaneous labor. Subjects were placed into three subgroups, defined by active labor duration from 6 to 10 cm as less than the median, the median-95th, and >95th percentile based on contemporary labor curves published by Zhang et al. We evaluated the association between subgroups and cesarean delivery, chorioamnionitis, estimated blood loss, Apgar score < 7 at 5 minutes, and neonatal intensive care unit admission using logistic regression to estimate odds ratios (OR) and 95% confidence intervals (CI). Results Six-hundred forty two women met the inclusion criteria. Compared with women whose active labor was less than the median, the risk of cesarean was higher in the median-95th percentile ([adjusted OR, aOR] 3.1, 95% CI 1.8–5.5) and the >95th percentile ([aOR] 6.8, 95% CI 3.9–11.7) subgroups. There was an increased odds of chorioamnionitis in the median-95th percentile subgroup ([aOR] 2.5, 95% CI 1.1–5.9). Conclusion Chorioamnionitis and cesarean delivery increased significantly as labor duration exceeded the median. This study provides a better understanding regarding the potential risk of cesarean and chorioamnionitis using contemporary labor curves.

Background: A standard obstetric analgesic should have a good analgesic effect without reducing the intensity of uterine contraction. The present study aimed to evaluate and compare the efficacy of intramuscular tramadol and pethidine on labor pain and duration. Material and Methods: A total of 170 multigravida women in active labor were randomly assigned to two identical groups, so that 85 pregnant women received pethidine (50mg/2ml) and 85 pregnant women received tramadol (100mg/2ml) intramuscularly. Results: The labor duration in the tramadol group was shorter than in the pethidine group. In 1st stage of labor, 64.7% of the participants in the tramadol group received the drug for 120±30 minutes, while 67.1% in the pethidine group received the drug for 180±30 minutes. In the 2nd stage, 44.7% of the participants in the tramadol group received the drug for 15±5 minutes, while 51.8% in the pethidine group received the drug for 25±5 minutes. The Visual Analog Scale (VAS) was used before, and 1 and 3 hours after drug administration. The pethidine group obtained a lower VAS mean score compared to those in the tramadol group at 1 hour after drug administration (4 vs 6; P≤.001). Moreover, there was a significant higher level of vomiting and dizziness among women in the pethidine group (29.4% vs 1.2%; P≤.001). Conclusion: Tramadol appears to lead to a shorter labor duration and cause lower maternal side-effects, although its analgesic efficacy was not as much as pethidine.

Previous research has revealed that passive (involuntary inhalation) tobacco smoking during gestation can have adverse effects upon the developing fetus. These prior investigations did not concentrate on changes in fetal morphology. This study was undertaken to delineate fetal neural abnormalities at the ultrastructural level in mice pups exposed in utero to passive maternal smoking.Pregnant study animals, housed in a special chamber, were subjected to cigarette smoke daily from conception until delivery. Blood tests for determination of carbon monoxide levels were run at 15-18 days gestation. Sciatic nerve tissue from experimental and control animals were obtained following spontaneous delivery and fixed in 2.5% gluteraldehyde in 0.1M cacodylate buffer pH 7.3. The samples were post-fixed in osmium ferrocyanide (1:1 mixture of 1.5% aqueous OSO4 and 2.5% K4 Fe(CN)6). Following dehydration, the tissues were infiltrated with and embedded in Spurr. Sections were stained with uranyl acetate and lead citrate.

A case of prenatal ultrasound diagnosis of a rare congenital ovarian tumor is presented. By ultrasound examination at 36–37 weeks of gestation the intra-abdominal mass 66  47  74 mm occupying the entire abdominal cavity was discovered. At 38 weeks of pregnancy spontaneous delivery occurred with girl weight 2840 g. On the eighth day after birth the child has been successfully undergone surgery. Histological examination revealed congenital germ-cell tumor with structures of dysgerminoma and yolk sac tumor.
