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.

Primary peritoneal carcinosarcoma is extremely rare and only few cases have been reported in the literature to date. We herein present a case of carcinosarcoma of the Douglas pouch in a 73-year-old Japanese woman. The patient complained of fever and lower abdominal pain, and a large pelvic mass (>10 cm in diameter) was detected, with rectal invasion.

Malignant lymphoma of the uterine cervix presumptively diagnosed by Pap smear: A case report.

Malignant lymphoma of the uterine cervix is exceedingly rare and is difficult to diagnose by cervical cytology. The current study presents a case of malignant lymphoma of the uterine cervix that was presumptively diagnosed by cervical cancer screening in which the patient had no clinical symptoms. The anterior lip of the uterine cervix was occupied by a macroscopic hemorrhagic tumor.

Choosing the uterine preservation surgery for placental polyp determined by blood flow evaluation: A retrospective cohort study.

Background: A placental polyp is an intrauterine polypoid mass or pedunculated mass occurring from residual trophoblastic tissue following abortion, cesarean section or vaginal delivery. Recently uterine preservation surgery represented by transcervical resection (TCR) has been performed for placental polyps. However TCR without intravascular intervention, including uterine artery embolization (UAE) may cause profound bleeding which necessitate emergency laparotomy.

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.

Safety and efficacy of thromboprophylaxis using enoxaparin sodium after cesarean section: A multi-center study in Japan.

Objective: Pulmonary embolism (PE) is the leading cause of maternal death in developed countries, and the prevention of venous thromboembolism (VTE) is a pivotal part of current obstetric care. This study evaluated the safety and efficacy of enoxaparin sodium for thromboprophylaxis after cesarean section (C/S), and analyzed the risk factors associated with VTE.

Materials And Methods: One hundred and forty-three women deemed to be at high risk of postoperative deep vein thrombosis (DVT) were enrolled between January 2011 and May 2012 in seven institutions in Japan.

Adhesional omental hernia: A case report.

Introduction: Omental hernias are rare and difficult to diagnose preoperatively due to a lack of specific symptoms.

Presentation Of Case: We report a case of adhesional omental hernia diagnosed at laparoscopy. A 38 year-old female patient with evidence of a previous caesarean section presented with an acute abdomen.

Proteolytic activation of heparin-binding EGF-like growth factor by membrane-type matrix metalloproteinase-1 in ovarian carcinoma cells.

Increased expression of heparin-binding EGF-like growth factor (HB-EGF) and membrane-type matrix metalloproteinase-1 (MT1-MMP) is frequently associated with various types of malignant tumor. HB EGF-like growth factor has been reported to promote the malignant progression of ovarian carcinoma. Based on this finding, inhibition of HB-EGF activity with CRM197 is now under phase I clinical evaluation.

Acute pancreatitis occurring in the early postpartum period: a case report.

We report a case of acute pancreatitis, which occurred after delivery in a woman who had an uneventful course of pregnancy and parturition. A 17-year-old Japanese woman was referred to our department because of nausea and vomiting two hours after delivery, followed by severe abdominal and back pain. On admission, in addition to elevated serum and urine amylase, plain computed tomography demonstrated a swollen pancreas and high density in the peripancreatic lesion with a large amount of ascites, suggesting the presence of an inflammation of the pancreas as well as peripancreatic lesion.
