OBJECTIVE: This study aimed to clarify the maternal and neonatal outcomes based on the presence or absence of a Couvelaire uterus with placental abruption. METHODS: This single-center retrospective study was conducted at a tertiary perinatal center in Japan, including patients diagnosed with acute placental abruption who delivered live births via cesarean section between 2016 and 2023. Patients were divided into two groups based on the presence or absence of a Couvelaire uterus during surgery: the Couvelaire and normal uterus groups. Maternal and neonatal outcomes were assessed. RESULTS: This study included 76 patients: 24 in the Couvelaire group and 52 in the normal uterus group. No patients underwent hysterectomies. The Couvelaire group had significantly higher intraoperative blood loss (median 1152 vs 948 g, P = 0.010), blood transfusion rates (58% vs 31%, P = 0.022), fibrinogen administration rates (38% vs 13%, P = 0.038), intensive care unit/high care unit admission rates (29% vs 7.7%, P = 0.013), and disseminated intravascular coagulation complication rates (25% vs 7.7%, P = 0.038). There were no differences in birth weight, gestational age (median 2387 vs 2065 g, P = 0.082), Apgar score <4 at 5 min (4.2% vs 3.9%, P = 0.95), umbilical artery blood pH <7.1 (25% vs 22%, P = 0.82), and neonatal death (4.2% vs 1.9%, P = 0.57). CONCLUSION: A Couvelaire uterus indicated adverse maternal outcomes but not neonatal ones. Its presence necessitates preparation for blood transfusions and/or intensive patient follow-up.

In Japan, rubella antibodies are measured in all pregnant women in order to detect subclinical infection. The study aimed to assess the validity of measuring rubella antibodies to detect subclinical rubella among pregnant women in Japan. This single-center, retrospective study measured rubella hemagglutination inhibition (HI) titers and rubella-specific IgM antibody index values (IgM-values). IgM-values were measured by enzyme immunoassay, and IgM-values > 1.2 were considered positive. Of 14965 pregnant women who were included, 186 (1.2%) were IgM-positive. Only one patient was clinically diagnosed with rubella (HI titer, 1:2048; IgM-value, 10) and developed a fever and skin rash. She decided to terminate her pregnancy without a repeat blood test. Of the IgM-positive patients, 136 (73.1%) had rubella HI titers of < 1:256. The correlation coefficient of rubella HI titers and IgM-values was weakly positive (0.2527; p < 0.0001). This study showed that the single combination of rubella HI and rubella-specific IgM measurements alone did not detect subclinical rubella. Creating awareness among pregnant women by informing them that almost all rubella-specific IgM-positive individuals without symptoms are not acutely infected could decrease their anxiety and prevent unnecessary termination of pregnancies.

OBJECTIVES: We investigated quality of life (QOL) of patients who underwent total hysterectomy for benign uterine diseases using two surgical approaches: robotic-transvaginal natural orifice transluminal endoscopic surgery (R-vNOTES) and robot-assisted laparoscopic hysterectomy (RALH). STUDY DESIGN: This single-center retrospective study was conducted in a tertiary academic setting and included 65 patients who underwent robotic-assisted hysterectomy for benign uterine diseases. Total hysterectomy was performed using R-vNOTES or RALH by the same gynecologist between December 2021 and June 2022. The primary outcome was a comparison of QOL over time and complete QOL recovery (postoperative QOL score/preoperative QOL score ≥ 1) by postoperative day 28 (POD28) in the R-vNOTES and RALH groups. QOL was examined using EQ-5D-5L in this study. The secondary outcome was a comparison of the surgical outcomes in the R-vNOTES and RALH groups. RESULTS: Complete QOL recovery was achieved by 62.7% in the R-vNOTES group and 7.3% in the RALH group at POD7 (p <.001) and by 100% in the R-vNOTES group and 56.1％ in the RALH group at POD28 (p <.001). In a multivariable model, patients who underwent R-vNOTES achieved higher complete QOL recovery at POD 28 [adjusted hazard ratio: 4.03, 95% confidence interval: 2.03-8.04]. There was no significant difference between the R-vNOTES and RALH groups in terms of operating time (p =.07), intraoperative blood loss (p =.35), uterus weight (p =.76), or postoperative complications (p =.71). CONCLUSION: The R-vNOTES approach for total hysterectomy for benign uterine diseases provided better complete QOL recovery by POD28 compared to the RALH approach. The surgical outcomes for R-vNOTES were equivalent to those for RALH, suggesting that R-vNOTES may provide a safe approach for robot-assisted hysterectomy.

Lobular endocervical glandular hyperplasia (LEGH) is characterized by clinically profuse and watery vaginal discharge. In pregnancy with LEGH, with watery fluid leakage persisting throughout pregnancy, it is often difficult to visually diagnose PROM. Adding to this difficulty, auxiliary diagnostic tests might also show positive results, complicating treatment and management.

This study investigated the implementation status, attitudes, and practices regarding maternal pertussis vaccination in delivery facilities in Kanagawa, Japan. We conducted a questionnaire survey of pertussis vaccination during pregnancy at 125 delivery service facilities, excluding midwifery clinics, in Kanagawa Prefecture from June 18 to July 20, 2020. The questionnaire comprised multiple-choice items, with single or multiple answers depending on the question. Of the 125 facilities surveyed, valid responses were obtained from 72 facilities (58%). There were 41 primary clinics with birthing facilities (57%), 16 general hospitals (not designated perinatal centers) (22%), 10 regional perinatal centers (14%), and five tertiary perinatal centers (7%). None of the facilities administered pertussis vaccination during pregnancy. Forty facilities (56%) reported knowledge of the severity of neonatal and infant pertussis infections. Twenty-three facilities (32%) reported knowledge of the prevention of pertussis infection by vaccination during pregnancy. All facilities reported willingness to consider vaccination if included in the Japanese guidelines. In Japan, the pertussis vaccination during pregnancy is not highly practiced by obstetricians; thus, it is not as popular as in other countries. Further studies are needed to promote strategies to prevent pertussis infection in the neonatal and infant periods.
