Nationwide survey of Japanese breast oncology and reproductive endocrinology departments about the impact of breast cancer treatment on fertility.

The purpose of this study is to assess the impact of breast cancer treatment on the reproductive potential. We conducted a nationwide survey of breast oncology and reproductive endocrinology and infertility (REI) departments using a questionnaire designed to assess the impact of breast cancer treatment on fertility. We received responses from 312 breast oncology departments (response rate, 31.

Successfully treated abdominal pregnancy causing hemoperitoneum using combined surgical and systemic methotrexate therapy: a case report and review of cases treated at Kyushu University Hospital.

Abdominal pregnancy is a rare condition that accounts for only 1% of all ectopic pregnancies but results in high maternal morbidity and mortality. We present a case of abdominal pregnancy with massive peritoneal bleeding successfully treated using systemic methotrexate (MTX). A 34-year-old woman with amenorrhea for 8 weeks and a positive pregnancy test was referred for evaluation of ectopic pregnancy.

Interstitial pregnancy in a woman with congenital afibrinogenemia.

Without fibrinogen replacement, pregnancies in patients with congenital afibrinogenemia end in miscarriage between 6 and 8 weeks of gestation. Studies in animal models suggest that disturbance of the embryo's decidual attachment contributes to miscarriage in afibrinogenemia. Ectopic pregnancy in human congenital afibrinogenemia has not been previously documented.

Allopregnanolone enhancement of GABAergic transmission in rat medial preoptic area neurons.

Gamma-aminobutyric acid (GABA)-mediated transmission in the medial preoptic area (MPOA) of the hypothalamus plays an important role in functions such as sex steroid hormone dynamics and control of body temperature. The action of allopregnanolone, the primary metabolite of progesterone, on GABAergic transmission was investigated by employing patch clamp whole cell recording on acutely dissociated rat MPOA neurons with the functional connection of presynaptic terminals. Allopregnanolone enhanced spontaneous GABA release on the MPOA neurons and induced prolonged decay of miniature GABAergic-inhibitory postsynaptic currents (mIPSCs).
