© 2015 Japan Society of Obstetrics and Gynecology. We report a case of marked elevation of the procalcitonin level in umbilical blood and neonatal blood at birth. The mother did not perceive fetal motion. Antepartum fetal heart rate monitoring showed a loss of variability and absence of acceleration. No fetal breathing movement, fetal movement, or fetal tone were observed by ultrasonography. The female neonate was delivered by cesarean section at 25-weeks of gestation, with birthweight 774-g. The umbilical arterial pH value at birth was 7.29. Mild elevation in interleukin-6 and tumor necrosis factor-α in umbilical blood were observed. Cytochrome c showed a high level in umbilical and neonatal blood at birth. Placental histopathology revealed multiple fetal vessel thrombosis in the large stem villi and chorionic vessels. The neonate showed no infectious signs throughout the neonatal period. Computed tomography at 3-months of age revealed atrophy in the cerebrum and cerebellum. At 1-year after birth, the infant showed spastic quadriplegia. In this case, antepartum asphyxia due to fetal vessel thrombosis may have influenced the elevation of procalcitonin level in umbilical blood and neonatal blood at birth.

We describe a prenatally diagnosed case with congenital infantile fibrosarcoma, which is a rare malignant tumor, of which there have been only 14 cases reported in the English literature. A giant mass on the left thigh was detected at 24 weeks' gestation by prenatal ultrasonography. Because of its rapid growth and nonreassuring fetal status in utero, the baby was delivered by cesarean delivery at 27 weeks' gestation. The case was complicated by hemorrhagic anemia, coagulopathy, and cardiac failure, and a tumor resection was performed on day 3. As of age 2.5 years, he was healthy without evidence of recurrence. Because some fetal cases with congenital infantile fibrosarcoma have a poor prognosis, termination of pregnancy at an appropriate time and postnatal early treatment are crucial for successful treatment. © 2012 Elsevier Inc.

We report a case of delayed-interval delivery of a dichorionic, diamniotic twin pregnancy with the survival of both twins. The patient presented at 22 weeks and 1 day of gestation with vaginal bleeding and preterm labor. Five days later, the first twin was born. The second twin remained in utero. The management consisted of careful monitoring of both maternal and fetal status. Nine days later, the second twin was delivered vaginally. Both twins received full resuscitation and immediate life-support intervention; at 7 years of age both twins exhibited normal development. © 2012 2012 Japan Society of Obstetrics and Gynecology.
