The purpose of this study was to investigate the fetal circulatory responses during maternal hemorrhage. Five pregnant goats with fetuses with a mean gestational age of 132 +/- 2 days were used. The maternal blood was withdrawn at 350 ml/h for 2 hours (e.g. 700 ml, 11.9 ml/kg maternal weight) and reinfused at the same speed. During maternal bleeding, maternal arterial pressure (MAP) gradually decreased. As a result of this maternal hypotension, fetal arterial pO2 and pH decreased, and PCO2 increased. After the reinfusion, fetal pO2 recovered but pH and PCO2 did not recover. Fetal arterial pressure (FAP) increased and heart rate (FHR) decreased during maternal bleeding and returned to the control level, after the reinfusion. Fetal arginine vasopressin (AVP) concentration increased to 401.2 +/- 318.5 pg/ml at the maximum bleeding. There were significant positive correlation between AVP concentration and FAP, and negative correlation between AVP and FHR during maternal bleeding. Therefore, we concluded that 700 ml maternal bleeding for 2 hours resulted the decrease in fetal pH, pO2, and FHR, and increase in PCO2, FAP, and AVP concentration. Fetal pH, PCO2, and AVP did not return to the control level in spite of reinfusion.

A rare case of primary squamous cell carcinoma of the endometrium, probably originating from adenomyosis, is presented. A 58-year-old Japanese woman was referred to Kitasato Institution Medical Center Hospital to explore the cause of her postmenopausal bleeding. The endometrial cytology specimen obtained with the Endocyte (an device for endometrial check up) showed cells suggesting well differentiated squamous cell carcinoma. The patient underwent modified radical hysterectomy, bilateral salpingo-oophorectomy, and pelvic lymphadenectomy, followed by postoperative radiation therapy. The dissected uterus revealed keratinizing-type squamous cell carcinoma localized in the fundal portion of the uterine body and invading deeply into the myometrium, coexistent with a large area of adenomyosis with a transitional area to carcinoma. The residual endometrium was atrophic. There was no atypical finding in the cervix. Human papilloma virus DNA was not detected. The carcinoma recurred 26 months after the surgery, and the patient died of the disease.
