Uterine cervical edema following cerclage.

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

Role of a Fetal Ultrasound Clinic in Promoting Multidisciplinary and Inter-Facility Perinatal Care.

Background: With the increasing rate of high-risk pregnancies, there is an increased need for early evaluation of at-risk fetuses. Fetal ultrasound imaging has become a pivotal part of this evaluation.

Methods: To evaluate the role played by a fetal ultrasound clinic in promoting comprehensive perinatal care of patients with high-risk pregnancies, we retrospectively analyzed the indications and findings of fetal scans and the outcomes of the examined fetuses collected over the past 7 years (2014-2020) by our institute, which is reorganized as a perinatal medical center.

Use of tumor markers to distinguish endometriosis-related ovarian neoplasms from ovarian endometrioma.

Objective: Only few studies have focused on tumor markers used in the preoperative diagnosis of endometriosis-related ovarian neoplasms, and previous studies have only assessed serum CA125 levels. This study investigated the significance of preoperative tumor markers and clinical characteristics in distinguishing endometriosis-related ovarian neoplasms from ovarian endometrioma.

Methods: A case-control study was conducted on 283 women who were diagnosed with confirmed pathology with endometriosis-related ovarian neoplasms (n=21) and ovarian endometrioma (n=262) at a single institution from April 2008 to April 2018.

Efficacy of Hormonal Therapies for Decreasing Uterine Volume in Patients with Adenomyosis.

Study Objective: The aim of this study is to evaluate the efficacy of hormonal therapies for inhibiting an increase in uterine volume in patients with adenomyosis.

Design: This was retrospective cohort study.

Setting: This study was conducted at Nippon Medical School Musashikosugi Hospital.

The presence of amniotic fluid sludge in pregnant women with a short cervix: an independent risk of preterm delivery.

: To examine whether the presence of amniotic fluid sludge (AFS) could increase the risk of preterm delivery in women with a cervical length (CL) of less than 25 mm. This is a retrospective cohort study of 110 women who were 14-30 weeks pregnant with a singleton gestation and a CL of less than 25 mm. The primary outcomes were defined as preterm delivery before 34 weeks and preterm delivery before 37 weeks.

Improving the Accuracy of Diagnosing Placenta Previa on Transvaginal Ultrasound by Distinguishing between the Uterine Isthmus and Cervix: A Prospective Multicenter Observational Study.

Objective: To clarify whether distinguishing between the uterine isthmus and cervix can improve the accuracy of diagnosing placenta previa at term.

Methods: A multicenter prospective observational study was conducted among pregnant women with suspected placenta previa at 20-24 weeks' gestation. Subjects were divided into the open isthmus group and closed isthmus group.

Reversible posterior leukoencephalopathy syndrome due to eclampsia in a woman with a twin pregnancy produced with donated oocytes.

A 35-year-old primigravida with severe ovarian dysfunction underwent in vitro fertilization with oocytes donated by her sister. A twin pregnancy ensued, and she received prenatal care at our hospital. She underwent a cesarean section at 35 weeks' gestation because of pregnancy-induced hypertension (PIH) and breech presentation at the onset of labor.

Significance of cervical gland area in predicting preterm birth for patients with threatened preterm delivery: comparison with cervical length and fetal fibronectin.

Background/aims: Absent cervical gland area (CGA) has been considered a predictor of preterm delivery (PTD) for women at low risk. Predictive efficacy was analyzed in women at high risk for PTD and compared with cervical length (CL) <20 mm and fetal fibronectin (fFN) in cervicovaginal secretions.

Methods: Case notes were reviewed for 108 subjects with gestation of 22-33 weeks who had been admitted to hospital with threatened PTD.

Is transvaginal ultrasonography at mid-trimester useful for predicting early spontaneous preterm birth?

Numerous reports have examined the relationship between sonographically determined cervical length and spontaneous preterm birth. Moreover, large screening studies have consistently demonstrated that the shorter the cervical length, the higher the rate of spontaneous preterm delivery. However, the sensitivity and positive predictive value of the cervical length for detecting preterm birth were low.

Detection of the cervical gland area in threatened preterm labor using transvaginal sonography in the assessment of cervical maturation and the outcome of pregnancy.

Objectives: To detect the cervical gland area in threatened preterm labor, and to determine its detection rate and relationship with cervical maturation and outcome of pregnancy in preterm labor.

Methods: This was a mixed longitudinal and cross-sectional study involving 615 transvaginal scans performed to detect the cervical gland area and measure cervical length in 101 singleton pregnancies with threatened preterm labor. The patients were treated with intravenous administration of ritodrine chloride for regular uterine contractions at 16-35 weeks of gestation.
