Incidence and risk factors for postpartum hemorrhage among transvaginal deliveries at a tertiary perinatal medical facility in Japan.

Postpartum hemorrhage (PPH) remains a leading cause of maternal death worldwide, and it is important to understand the relative contributions of different risk factors. We assessed the incidence of these among cases of transvaginal delivery. Between June 2013 and July 2016, a prospective cohort study was conducted at a tertiary perinatal medical facility in Japan.

Case of uterine rupture after multiple intrauterine operations and uterine artery embolization.

Uterine rupture is rare but may result in both maternal and fetal death. The factors involved in such deaths depend on each case, but uterine artery embolization (UAE), the common treatment for hemorrhage, is possibly one factor. UAE may be related to uterine rupture or placenta accreta, but few data exist regarding UAE and uterine rupture.

Primary peritoneal carcinosarcoma arising from the Douglas pouch: A case report.

Monochorionic-diamniotic discordant growth in a twin pregnancy with one fetus affected by Ebstein's anomaly of tricuspid leaflets.

Our patient was diagnosed as having discordant twin growth with Ebstein's anomaly in the larger fetus. Cardiac function was deteriorated in accordance with progression of gestational age. Our observation indicated cardiac failure of the larger fetus.

Positron Emission Tomography Findings in Atypical Polypoid Adenomyoma.

Atypical polypoid adenomyoma (APAM) is a rare polypoid tumor of the uterus composed of atypical endometrial glands surrounded by smooth muscle. A 29-year-old nulligravida, was clinically diagnosed with endocervical myoma and underwent trans-uterine cervical resection with hysteroscope. The histopathological diagnosis of specimens was APAM.

Chorioamnionitis caused by Staphylococcus aureus with intact membranes in a term pregnancy: A case of maternal and fetal septic shock.

Chorioamnionitis is usually caused by migration of cervicovaginal flora through the cervical canal in women with ruptured membranes. Common causative pathogens are genital mycoplasmas, anaerobes, enteric gram-negative bacilli, and group B streptococcus. There have been only seven previous reports of chorioamnionitis due to Staphylococcus aureus and their clinical courses are characterized by rapid disease progression and poor prognosis.
