Abstract

Clinical guidelines for obstetrical practice were first published by the Japan Society of Obstetrics and Gynecology (JSOG) and the Japan Association of Obstetricians and Gynecologists (JAOG) in 2008, and a revised version was published in 2011. The aims of this publication include the determination of current standard care practices for pregnant women in Japan, the widespread use of standard care practices, the enhancement of safety in obstetrical practice, the reduction in burdens associated with medico-legal and medico-economical problems, and a better understanding between pregnant women and maternity-service providers. These guidelines include a total of 87 Clinical Questions followed by several Answers (CQ&A), a Discussion, a List of References, and some Tables and Figures covering common problems and questions encountered in obstetrical practice. Each answer with a recommendation level of A, B or C has been prepared based principally on "evidence" or a consensus among Japanese obstetricians in situations where "evidence" is weak or lacking. Answers with a recommendation level of A or B represent current standard care practices in Japan. All 87 CQ&As are presented herein to promote a better understanding of the current standard care practices for pregnant women in Japan.

Abstract

Objectives: To clarify the clinical risk factors associated with poor neonatal outcomes due to umbilical cord prolapse (UCP).Methods: A postal questionnaire survey was attempted in Japan. The clinical risk factors and managements associated with poor neonatal outcomes were analyzed in cases of UCP treated in Japan.Results: A total of 267 cases of UCP (out of 2 037 460 total deliveries) were analyzed. The rates of intrauterine death, neonatal death and survival with disability were 3.4%, 5.6% and 7.1%, respectively. The multivariate regression analysis for these poor neonatal outcomes revealed that the significant risk factors included a prolapsed amniotic sac (adjusted odds ratio (aOR), 4.49), preterm labor (aOR, 2.99) and replacement of the prolapsed umbilical cord into the uterus (aOR, 2.87). However, UCP that occurred during labor (aOR, 0.28) and emergency cesarean section (aOR, 0.11) were associated with a reduction in the rates of poor outcomes. The interval between the diagnosis of UCP and delivery was significantly longer in the infants with a poor outcome than intact survival (median 30 versus 24 min, p = 0.048).Conclusion: An emergency cesarean section should be carried out immediately to ensure a better outcome for the infant.

14. TWO CASES OF H-Y ANTIGEN POSITIVE 46 XX MALE: CASE REPORT

Abstract

Two cases of phenotypic males with 46XX karyotype are reported. The first case is a 41-yearold married man. He complained of sterility and had hypoplastic testes without other clinical symptoms of abnormal sexual development. The second case is a 35-year-old married man. He also complained of sterility. The external genitalia appeared normal in size, but small testes and gynecomastia were noted. In each cases, pituitary gonadotropin excretion was elevated. Serum testosterone level was low in one case. To certify the hypothesis that H-Y antigen is essential for testicular differentiation, we studied two our cases. H-Y antigen can be detected by the cytotoxicity test in vitro. Blood cells from two XX males (our cases) expressed H-Y antigen. The clinical features, etiology of XX male syndrome are discussed and the literature is reviewed.

Abstract

Background: To clarify whether the use of balloons for cervical ripening is associated with the incidence of umbilical cord prolapse., Methods: A postal questionnaire survey was distributed in Japan. Cases of umbilical cord prolapse occurring during labor in association with the use of balloons for cervical ripening between 2007 and 2011 in Japan were analyzed., Results: Answers from 942 institutions were obtained. The subjects included 369 patients with fore-lying or prolapse of the umbilical cord among a total of 2,037,460 deliveries. Among the singleton vertex cases, fore-lying or prolapse of the umbilical cord during labor were observed in 88 (0.005%) of 1,891,189 deliveries not associated with the use of balloons for cervical ripening and in 93 (0.064%) of 146,271 deliveries associated with the use of balloons for cervical ripening (Odds ratio 13.67, 95% confidence interval 10.21, 18.30). All types of balloons were significantly associated with the occurrence of fore-lying or prolapse of the umbilical cord. A total of 39% of cases of umbilical cord prolapse occurred during manual or spontaneous balloon removal, while 53% of cases occurred after a while not directly associated with balloon removal., Conclusion: The risk of umbilical cord prolapse was significantly increased during the use of balloons for cervical ripening, especially in cases involving the use of disk-type and ball-type balloons filled with large amounts of water.
