We present a boy and two girls with paternal uniparental disomy of chromosome 14q (patUPD14). One girl had a Robertsonian translocation, whereas two a normal karyotype. Based on the manifestations of these patients and four previously reported patients who all had translocated chromosome 14, The patUPD14 was thought to constitute a distinctive syndrome. The(More)
OBJECTIVE Our purpose was to examine the significance of diffuse chorioamniotic hemosiderosis (DCH) on neonatal morbidity and mortality. METHODS Using data from a retrospective case-control study, we analyzed 46 singleton placentas with DCH from infants who were delivered and/or admitted to the neonatal intensive care unit of Kanagawa Children's Medical(More)
To investigate the pregnancy outcome of fetuses affected with trisomy 18, we analyzed 63 cases diagnosed at our hospital from January 1993 to December 2004. Twenty-nine were males and 34 were females. Fifty-eight were prenatally diagnosed, and in 16 (27.6%) of them intrauterine fetal death (IUFD) occurred between 28 weeks and 41 weeks gestation (34.6 +/-(More)
INTRODUCTION Fetus-in-fetu is a rare congenital fetiform mass whose etiology is still controversial. We report two cases of fetus-in-fetu. CASE 1: A fetal retroperitoneal cystic tumor including two masses was detected by ultrasonography at 26 gestational weeks. The masses showed distinctive structures resembling a vertebral axis and were prenatally(More)
To evaluate whether the routinely collected data in birth defect registries could be used to assess association between medications and risk for congenital anomalies an "exposed case-only" design was performed. Twelve registries provided 18,131 cases exposed to a medication during the first trimester of pregnancy and with at least one major malformation.(More)
AIM This study of pregnant women was undertaken to clarify their immune status for rubella and to evaluate the efficacy of, and adverse reaction to, post-partum rubella vaccination. METHODS We determined the levels of both rubella antibody by hemagglutination inhibition test and IgM antibody by enzyme-linked immunosorbent assay in the first gestational(More)
AIM We examined birth-related malpractice civil litigation cases in Japan to clarify the actual status related to the implementation of an obstetrical no-fault compensation system in 2009. MATERIAL & METHODS In this retrospective review, we analyzed legal and medical information from 64 cases with a delivery date after 1987 and a judgment date between(More)
We report a female fetus with sirenomelia with 46,X,t(X;16)(p11.23;p12.3) de novo. Fluorescence in situ hybridization (FISH) with bacterial artificial chromosomes were employed for narrowing down the breakpoint regions. On chromosome 16, the breakpoint was mapped in the region of RP11-453F10 (19 920 640-20 118 153 bp from 16pter). On chromosome X, the(More)

Our purpose is to prove that prolonged inflammation of the chorionic plate, which we have termed subacute chorioamnionitis (SCAM), is a distinctive entity and should be differentiated from acute chorioamnionitis (ACAM) because it is an excellent prognostic indicator of chronic lung disease (CLD), including Wilson-Mikity syndrome (WMS). Ninety singleton(More)
