Polycystic ovary syndrome (PCOS) is a common endocrine disorder characterized by insulin resistance and hyperandrogenism. The interaction of these factors might result in increased risks of miscarriage and pregnancy complications such as gestational diabetes mellitus (GDM). To examine the pregnancy risks in women with PCOS, we compared obstetrical outcomes(More)
Umbilical arteriovenous malformation (AVM) is a rare congenital malformation. We report a case of umbilical AVM that was prenatally diagnosed by further color Doppler ultrasonography because of fetal cardiomegaly. At 35 weeks gestation, a male newborn was delivered by emergent cesarean section because of rapid progress of cardiomegaly and breech(More)
Interrupted aortic arch (IAA) is fatal if not diagnosed. Prenatal diagnosis is helpful, but it is difficult to detect IAA and even more so to differentiate types A and B prenatally. Our objectives were to find a way to detect IAA using 2 views-three-vessel view (3VV) and four-chamber view (4CV)-and to differentiate between types A and B. We retrospectively(More)
A high performance liquid chromatographic (HPLC) method with electrochemical detection (ECD) was developed for the simultaneous measurement of estrone, estradiol, estriol and estetrol in serum. These hormones were extracted with diethylether, chromatographed on an silica-octadecyl silane (ODS) column with an eluent of phosphate buffer(More)
We continuously measured bilateral uterine artery (UA) blood flow and compared differences in UA blood flow to investigate the differences in pathophysiology between early- and late-onset pregnancy-induced hypertension (PIH) and the usefulness of continuous monitoring of UA blood flow for the prediction of early-onset PIH. The subjects were 76 PIH patients.(More)
Hypertrophic obstructive cardiomyopathy (HOCM) is cardiac hypertrophy of ventricular myocardium with left ventricular outflow tract obstruction. We report a pregnancy with HOCM after defibrillator implantation surgery. The patient was a 33-year-old nulligravida and was categorized as New York Heart Association class II. Her brain natriuretic peptide (BNP)(More)
AIM We created a new reference standard focusing on the hemispheric anteroposterior cerebellar diameter (APCD) in addition to the transverse cerebellar diameter (TCD) and discussed whether or not the cerebellar measurement was useful for the detection of trisomy 18 (T18). MATERIAL AND METHODS In 150 normal fetuses between 14 and 36 weeks of gestational(More)
Although gestational hypertension (GH) is thought to be different from preeclampsia (PE), in Japan GH and PE are usually treated as the same disease (i.e., pregnancy-induced hypertension). Here we sought to determine whether there are any differences in fetal growth and maternal kidney function between pregnancies with PE and those with GH. We(More)
