Risk Factors for Intrapartum Anorectal Mucosal Lacerations and Rectovaginal Fistula: A Retrospective Comparative Study.

Introduction: We examined the risk factors for fourth-degree perineal lacerations (intrapartum anorectal mucosal lacerations) and rectovaginal fistulas as one of the later complications.

Methods: We reviewed the obstetric records of all singleton vaginal deliveries after 22 weeks of gestation at our institute between January 2006 and December 2018 (n = 19,370).

Results: Of the 19,370 deliveries, 61 had fourth-degree perineal lacerations (0.

Prophylactic Cervical Cerclage in Cases Following Cervical Conization at a Japanese Perinatal Center.

The objective of this study was to re-examine the effect of cerclage on the possible factors associated with preterm delivery in women who had cervical conization. This was a retrospective cohort study comparing the obstetric outcomes of women with or without prophylactic cervical cerclage in pregnancy following a prior conization and managed at our institute between 2004 and 2023. In this study, there were 75% of pregnant women with a history of cervical conization.

A Retrospective Comparative Study of the Effect of Controlled-Release Dinoprostone Vaginal Delivery System (Propess®) and Mechanical Methods for Cervical Ripening in Nulliparous Women in Late-Term Pregnancy.

Objective: The effects of the controlled-release dinoprostone vaginal delivery system (Propess) and mechanical methods for cervical ripening in nulliparous women in late-term pregnancy were compared retrospectively.

Methods: This retrospective comparative study included 46 nulliparous pregnant women (24 in the Propess group and 22 in the mechanical methods groups) with a low Bishop score (≤1) who needed labor induction at 41 weeks of gestation. The primary outcome was the success rate of cervical ripening (= Bishop score >6 or vaginal delivery) by the next day following the insertion of Propessonly or mechanical cervical dilation only.

Clinical Factors Predicting Disseminated Intravascular Coagulation (DIC) in Women With Placental Abruption and a Live Fetus.

Objective: We examined predicting factors other than blood test results for disseminated intravascular coagulation (DIC) in patients with placental abruption and a live fetus who were transported by ambulance to our institute.

Methods: We reviewed the obstetric records of 60 singleton deliveries between January 2006 and December 2018. In this study, we excluded four cases with fetal demise at the time of transportation.

Comparison of Obstetric Outcomes Between Controlled-Release Dinoprostone Vaginal Delivery System (PROPESS) and Administration of Oral Dinoprostone for Labor Induction in Multiparous Women at Term.

Objective: The aim of this study was to compare the rate of vaginal delivery and adverse outcomes of a controlled-release dinoprostone vaginal delivery system (PROPESS) and the administration of oral dinoprostone for labor induction in multiparous women at term.

Methods: This retrospective case-controlled study included 92 multiparous pregnant women (46 and 46 in the PROPESS and oral dinoprostone groups, respectively) who required labor induction at ≥37 weeks of gestation. The primary outcome was the success rate of vaginal delivery following the insertion of PROPESS only or the administration of oral dinoprostone (up to six tablets) only.

Transmission of the Herpes Simplex Virus in the Preclinical Phase of Disease Progression during Childbirth.

Vertical transmission of the herpes simplex virus (HSV) in the preclinical phase of the disease progression is rare. Here, we present a case of perinatal-acquired herpes from an asymptomatic mother. Our findings suggest that clinicians should consider screening predisposed mothers for HSV as part of prenatal care to identify asymptomatic primary genital HSV infections.

Recent Status of Pregnancies at an Advanced Maternal Age at a Japanese Perinatal Center.

Objective We compared the recent obstetric outcomes of women aged 40 and over as advanced maternal age (AMA) to those with AMA more than 10 years ago. Methods This was a retrospective study of primiparous singleton pregnancies who delivered at ≥22 weeks of gestation managed at Japanese Red Cross Katsushika Maternity Hospital between 2003-2007 and 2013-2017. Results The percentage of primiparous women aged with AMA who delivered at ≥22 weeks of gestation increased from 1.

Subsidies for Pregnant Women with "Genuinely Unavoidable Special Reasons".

Here, we present two cases of women with social problems whose delivery and hospitalization costs were fully subsidized by the revised Hospitalization Assistance Policy Program. The presence of the program is required to be enlightened and expanded in Japan.

Uterine cervical edema following cerclage.

We present a case of large uterine cervical edema following cerclage during pregnancy.

Antimicrobial Resistance for Genital Infection during Pregnancy in Japan.

The current study examined the antimicrobial resistance of (CT) genital infection during pregnancy in Japan. We requested 2,146 obstetrical facilities that are members of Japan Association of Obstetricians and Gynecologists to provide information of CT screening tests and antimicrobial resistance in pregnant women between April 2020 and March 2021. The prevalence of CT genital infection in Japan was 2.

Twin anemia-polycythemia sequence with suspected cardiac dysfunction.

We present a case of twin anemia-polycythemia sequence diagnosed postnatally with suspected chronic stress on the heart in the donor twin.

Proportion of Late Pregnant Women with Anxiety Symptom under COVID-19 Pandemic in Japan.

Introduction: The COVID-19 pandemic has caused stress and anxiety for pregnant women worldwide. We examined the anxiety symptom in Japanese women during pregnancy using a self-administered questionnaire under the COVID-19 pandemic.

Methods: Between April 2020 and March 2021 (2020, the COVID-19 pandemic), we asked 248 Japanese women without history of mental disorders who delivered singleton neonates at 37-41 weeks' gestation to answer the two-item generalized anxiety disorder scale (GAD-2) at first, second, and third trimesters of gestation.

Appropriate Support for "Specified Expectant Mothers".

"Specified expectant mothers" are defined as pregnant women at high risk of needing extra support after birth. To provide them appropriate support, the methods for evaluating specified expectant mothers should be standardized. Thus, in this study, I reviewed the evaluation and multidisciplinary collaboration in some regions reported to be actively supporting specified expectant mothers in Japan.

Fetomaternal hemorrhage occurred in one fetus of dichorionic twin pregnancy.

In a twin pregnancy, it may be difficult to notice the decreased fetal movements, which is one of the main symptoms of fetomaternal hemorrhage, in one fetus due to the movements of the other fetus.
