Factors associated with intrapartum cesarean section in women aged 40 years or older: a single-center experience in Japan.

To elucidate the efficacy and safety of attempting a vaginal birth and to understand the factors that contribute to the increased risk of operative delivery in women aged 40 years or older. A database of the Japanese Red Cross Nagoya Daiichi Hospital was reviewed to identify women aged 40 years or older with singleton, vertex, and vital pregnancies who attempted vaginal delivery at and after 37 + 0 gestational weeks between January 2011 and December 2016. A total of 415 women met the criteria for inclusion in this study, including 372 and 43 women who gave birth by vaginal delivery and by intrapartum cesarean section (CS), respectively.

Continuous amnioinfusion in women with PPROM at periviable gestational ages.

To elucidate the efficacy of continuous amnioinfusion on perinatal outcome in women with preterm premature rupture of membranes (PPROM) at periviable gestational ages. A database was reviewed to identify women with singleton pregnancies who were admitted to the Japanese Red Cross Nagoya Daiichi Hospital due to PPROM before 26 + 0-week gestation between July 2009 and July 2017. A total of 81 women met the criteria for inclusion in this study including 70 and 11 women with and without amnioinfusion, respectively.

Factors associated with delivery at or after 28 weeks gestation in women with bulging fetal membranes before 26 weeks gestation.

Objective: To elucidate the factors that contribute to prolonged pregnancy and promote neonate survival in women with bulging fetal membranes.

Methods: A database was reviewed to identify women with singleton pregnancies who underwent amniocentesis on admission to determine amniotic fluid neutrophil elastase levels before 26 + 0 weeks gestation between July 2001 and January 2015. Following delivery, the placentas of these patients were examined for histologic chorioamnionitis.

[Granulosa cell tumor of the ovary - analysis of 15 cases in a single institution].

The best treatment for recurrent granulosa cell tumor(GCT)is considered to be surgical resection, because the effects of chemotherapy or radiation on GCT are obscure. The common site of recurrence is the pelvic cavity, including the surface of the liver and intestine as tumor-dissemination-patterns. Between June 1988 and June 2011, we treated 15 patients with GCT at our hospital.
