Japan has been reported to be one of the areas of highest prevalence of human T-cell leukemia virus type 1 (HTLV-1) in the world [1,2]. For example, our earlier study indicated that about 1620 of HTLV-1 carriers have births per year in Japan [3]. To prevent mother-to-child infection of HTLV-1, Japanese obstetricians have to instruct these women about the methods as alternatives to breast-feeding [1,4].

In the United States and some European countries, the average length of postpartum hospital stay after vaginal and cesarean deliveries is 1-2 and 3-4 days, respectively [1-3]. However, in Japan it is usually 4-6 and 6-10 days, respectively. During the longer hospitalization after deliveries, in Japan, women usually rest for health recovery and receive guidance from midwives about baby care such as breastfeeding. To date, cesarean delivery has contributed to the decreased prevalence of exclusive breastfeeding [4-7]; however, the longer guidance regarding breastfeeding following cesarean delivery compared with vaginal delivery in Japan may contribute to an increased rate of exclusive breastfeeding.

The woman was a 40-year-old, gravida 2, para 1. Her first pregnancy was uneventful and ended in a vaginal delivery of a healthy male infant weighing 3,078 g at 41 weeks' gestation. She and her husband had unremarkable medical and family histories. During the 1st and 2nd trimesters of the current pregnancy, her antenatal progress had been uneventful. Uneventful amniocentesis at 17 weeks confirmed a normal female karyotype. At a gestation of 38 weeks and 2 days, no abnormal findings were detected in the uterus by routine ultra-sonography; however, at 39 weeks and 2 days an intrauterine cystic echo-free area (5.2 X 4.4 X 2.2 cm) sited between the anterior uterine wall and the membranes was identified (Figure 1). The edge of the echo-free area was 3-4 cm away from the border of the placenta. A subchorionic haematoma was suspected. The normally thick placen-tal tissue was located on the right side of the fundus and the fetal anatomy was normal. At the time, she had no pain or bleeding.

Objective: This study was to examine the clinical usefulness of expectant management of early-onset severe preeclampsia.Methods: We reviewed the obstetric records of all Japanese singleton deliveries at ≥22 weeks' gestation managed at Japanese Red Cross Katsushika Maternity Hospital between 2007 and 2012. We compared the obstetric characteristics and perinatal outcomes between the cases of deliveries before (n = 19) and after completion of corticosteroids (n = 30) (immediate delivery versus expectant management).Results: Although the gestational age at delivery in the patients expectantly managed was higher than that in the patients required immediate deliveries (31.0 versus 29.3 weeks), the difference in the incidence of neonatal respiratory distress syndrome between the two groups did not reach the statistical significance (74 versus 47%, p = 0.06). The incidence of pulmonary edema in the patients expectantly managed was significantly higher than that in the patients required immediate deliveries within the first 48 h (20 versus 0%, p = 0.04).Conclusion: The current results could not support the clinical usefulness of expectant management of early-onset severe preeclampsia.

Despite the great studies made in the reduction of pregnancy-related maternal mortality, hemorrhage remains a leading cause of maternal death. To further reduce the maternal mortality rate, the risk factors related to hemorrhage must be identified. Some previous studies have identified prolonged labor, preeclampsia, macrosomia, induction and/or augmentation of labor, forceps delivery, retained placenta and soft-tissue lacerations as major risk factors for severe postpartum hemorrhage . However, these previous studies may have some limitations such as a bias of including multiple pregnancies. In deliveries of multiple pregnancies, overdistention of the uterus may weaken the contraction and retraction of the uterine muscles and increase the risk of postpartum hemorrhage. In this study, therefore, we examined vaginal singleton deliveries to identify factors most strongly associated with the increased risk of severe postpartum hemorrhage needing transfusion.

Objective: We examined the clinical characteristics and obstetric outcomes in adolescent pregnancies in Japanese women. Methods: The present study was a retrospective investigation of all primiparous Japanese women with singleton pregnancies who gave birth at ≥22 weeks’ gestation aged ≤18 years old (adolescent pregnancy, n = 325) and aged 28–30 years old (n = 2029) at Japanese Red Cross, Katsushika Maternity Hospital between 2002 and 2016. Results: The frequencies of smoking, economic problems, an unmarried single status at delivery and the start of prenatal care in the first trimester in the adolescent pregnancy group were significantly higher than in the control group (p <.01). The incidences of Chlamydia trachomatis, Condyloma acuminatum, and mental disorders in the adolescent pregnancy group were significantly higher than in the control group (p <.01). Pregnancy in adolescence was not related to adverse obstetric outcomes except preterm delivery (p =.02). Conclusions: Adolescent pregnancy was not associated with adverse obstetric outcomes; however, adequate social, economic, and mental support is needed for adolescent pregnant women. ? 2018, ? 2018 Informa UK Limited, trading as Taylor & Francis Group.
