Only few studies have reported on Jra alloimmunization in pregnancy, and its clinical course remains unclear. We reviewed our cases to clarify the change in the peak systolic velocity of the middle cerebral artery (MCA-PSV) during pregnancy and the critical anti-Jra antibody titer to predict fetal anemia. We collected the data of pregnant women with anti-Jra antibody from two hospitals between 2010 and 2017. We extracted data on maternal information, number of intrauterine blood transfusions (IUT), trend of anti-Jra antibody titer, changes of MCA-PSV, and neonatal outcome. We had 16 cases. IUTs were performed in 6 fetuses with severe anemia between 27 and 32 weeks’ gestation. The MCA-PSV did not increase more than 1.5 multiples of the median (MoM) after 32 weeks’ gestation. No significant difference was found in the maximum titer between cases with IUT and those without IUT. All pregnancies but one delivered at term. No neonates developed severe anemia or jaundice. MCA-PSV did not increase higher than 1.5 MoM later during the pregnancy. A critical titer to predict fetal anemia did not exist. Spontaneous term delivery could be expected even in fetuses who underwent IUT before 32 weeks’ gestation.

Aim: The aim of the survey is to investigate current practice and complications of percutaneous umbilical cord blood sampling (PUBS) in Japan. Methods: In this retrospective survey, data including perioperative information, indications, details of the procedure and procedure-related complications were collected for patients who underwent PUBS between 2012 and 2016 in Japanese perinatal care centers. Results: One hundred and fifty-three patients underwent PUBS and a total of 223 procedures were analyzed in this study. Fetal anemia was the most common indication for PUBS, representing greater than 70% of all cases. Anemia specific to monochorionic twins, such as acute feto-fetal hemorrhage subsequent to single intrauterine fetal death (IUFD) and twin anemia-polycythemia sequence, were the leading causes of suspected fetal anemia. Maternal anesthetics were given during the procedure in 70% of cases. The PTC needle (Hakko, Japan) was most commonly used in the procedure. The most frequent complication was bleeding from the umbilical cord puncture site; however, it did not require immediate delivery during or after the procedure in any case. IUFD occurred in 11 (4.9%) procedures, 7 of which appeared to be related to the underlying fetal disease. The overall completion rate of the procedure was 97%. Conclusion: Percutaneous umbilical cord blood sampling was most commonly performed for the evaluation of fetal anemia, usually due to complications of monochorionic twins, followed by the measurement of fetal thyroid function. The safety and the completion rate of the procedure in Japan appear satisfactory.

Serous endometrial intraepithelial carcinoma (SEIC) is a rare but highly aggressive form of uterine endometrial cancer. We present a case of a premenopausal 42-year-old patient who presented with copious vaginal bleeding without a specific medical history. A total abdominal hysterectomy was performed. Pathologic results showed SEIC. We report this case and include a brief literature review.
