The use of balloons for uterine cervical ripening is associated with an increased risk of umbilical cord prolapse: population based questionnaire survey in Japan.

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.

Guidelines for obstetrical practice in Japan: Japan Society of Obstetrics and Gynecology (JSOG) and Japan Association of Obstetricians and Gynecologists (JAOG) 2014 edition.

The 'Clinical Guidelines for Obstetrical Practice, 2011 edition' were revised and published as a 2014 edition (in Japanese) in April 2014 by the Japan Society of Obstetrics and Gynecology and the Japan Association of Obstetricians and Gynecologists. 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 of burdens associated with medico-legal and medico-economical problems, and a better understanding between pregnant women and maternity-service providers. The number of Clinical Questions and Answers items increased from 87 in the 2011 edition to 104 in the 2014 edition. The Japanese 2014 version included a Discussion, a List of References, and some Tables and Figures following the Answers to the 104 Clinical Questions; these additional sections covered common problems and questions encountered in obstetrical practice, helping Japanese readers to achieve a comprehensive understanding. Each answer with a recommendation level of A, B or C was prepared based principally on 'evidence' or a consensus among Japanese obstetricians in situations where 'evidence' was weak or lacking. Answers with a recommendation level of A or B represent current standard care practices in Japan. All 104 Clinical Questions and Answers items, with the omission of the Discussion, List of References, and Tables and Figures, are presented herein to promote a better understanding among English readers of the current standard care practices for pregnant women in Japan.

Poor prognosis of ovarian cancer with large cell neuroendocrine carcinoma: case report and review of published works.

Large cell neuroendocrine carcinoma (LCNEC) is well-reported to result in unfavorable prognoses in many organ cancers while being rarely reported in gynecologic cancer, especially ovarian and endometrial cancers. Here we report a case of ovarian cancer with LCNEC which spread to distant organs within 1 year of primary surgery despite the fact that the post-surgical stage was Ia. The case received platinum-based chemotherapy as an adjuvant therapy after her curative surgery. However, LCNEC in the case was resistant to the chemotherapy. In our review of published works, ovarian cancer cases with LCNEC show poor prognoses regardless of adjuvant chemotherapy following complete resection. Median overall survival was 10 months in stage I cases. Development of chemotherapy sensitive for LCNEC is needed.

A feasibility study on maintenance of docetaxel after paclitaxel-carboplatin chemotherapy in patients with advanced ovarian cancer.

OBJECTIVE: To test the concept of taxane sequencing, this feasibility trial evaluated maintenance of docetaxel after paclitaxel and carboplatin combination chemotherapy in patients with stage IC-IV ovarian cancer. METHODS: All patients received debulking surgery followed by paclitaxel and carboplatin chemotherapy. Attainment of clinically defined complete or partial response was confirmed by image scanning. Maintenance of docetaxel started at an initial dose of 70 mg/m(2) every 4 weeks for 6 cycles and was extended to 10 cycles unless disease progression and/or recurrence during the protocol therapy or unacceptable toxicities were seen. RESULTS: Stage subsets in 20 eligible patients were as follows: IIIB, 2 patients (10%); IIIC, 13 patients (65%); IV, 5 patients (25%). Neutropenia was common (40% with grade 3 or 4) and was most frequent during first or second cycle although the disabling peripheral neuropathy was not observed. Twelve patients completed protocol therapy (6≤cycles), while 8 patients failed to complete 6-cycle chemotherapy, because of progressive disease (5 patients) or grade 4 toxicities (3 patients). Median PFS was 20 months and 3-year PFS rate was 12%. Median overall survival was 39 months and 3-year OS rate was 69%. CONCLUSION: Six cycles of single-agent docetaxel maintenance chemotherapy is feasible and generally tolerable to women with advanced ovarian cancer who attained a clinically defined response to initial paclitaxel and carboplatin based chemotherapy.

Guidelines for office gynecology in Japan: Japan Society of Obstetrics and Gynecology and Japan Association of Obstetricians and Gynecologists 2011 edition.

Gynecology in the office setting is developing worldwide. Clinical guidelines for office gynecology were first published by the Japan Society of Obstetrics and Gynecology and the Japan Association of Obstetricians and Gynecologists in 2011. These guidelines include a total of 72 clinical questions covering four areas (Infectious disease, Malignancies and benign tumors, Endocrinology and infertility, and Healthcare for women). These clinical questions were followed by several answers, backgrounds, explanations and references covering common problems and questions encountered in office gynecology. Each answer with a recommendation level of A, B or C has been prepared based principally on evidence or consensus among Japanese gynecologists.These guidelines would promote a better understanding of the current standard care practices for gynecologic outpatients in Japan.
