This report describes a pregnancy with a triploid fetus identified from a scan for anomalies at 18 weeks and confirmed by amniocentesis. A 29-year-old, primigravida woman was referred to our clinic for genetic counseling at 18 weeks of gestation because of a mild oligohydramnios due to amniotic fluid index (AFI) less than the fifth percentile in her 18th week. The woman underwent amniocentesis, which revealed a karyotype of 69,XXX. There was no consanguinity in this family. In postmortem evaluation, we encountered a hydrocephalic fetus with an aberrant skull shape, including dysplastic calvaria with large posterior fontanel, marked intrauterine growth retardation (IUGR) in addition to syndactyly of third and fourth fingers, exophthalmia, cleft palate, low set malformed ears, micrognathia and club foot...

Chronic abruption-oligohydramnios sequence (CAOS), characterized by chronic vaginal hemorrhage and oligohydramnios, is a rare clinical condition of pregnancy. Because CAOS is associated with preterm delivery and lung injury to the infant, it is a major clinical concern. This report describes three CAOS cases which presented characteristic MRI findings reflecting CAOS pathological mechanisms and pathological findings. First, in all cases, the placenta detached from the uterus at the peripheral portion of the placenta because of placental marginal hematoma...

BACKGROUND: Fetal weight estimation is one of the most important aspects of antenatal care. The effects of amniotic fluid volume on the accuracy of estimated fetal weight (EFW) depend on the amount of fluid, in particular whether it is polyhydramnios or oligohydramnios. Previous studies have reported conflicting results of the effects of amniotic fluid volume on EFW accuracy. AIM: The aim of the study was to evaluate the effects of isolated oligohydramnios cases and polyhydramnios on the accuracy of EFW...

Danshen extract has been used in the treatment of oligohydramnios, however, the mechanism of its action has not been elucidated. Previously, we demonstrated that down-regulation of AQP3 in fetal membranes may contribute to the development of oligohydramnios. In this study, we investigated the effects of Danshen extract on AQP3 expression in human amniotic epithelial cells from term pregnancies with oligohydramnios or those with those with (those with) normovolemic amniotic fluid. Human amniotic epithelial cells from the oligohydramnios group expressed a lower level of AQP3 mRNA and protein than those with normovolemia...

Introduction. Amniotic band syndrome and sequence are a relatively rare condition in which congenital anomalies occur as a result of the adherence and entrapment of fetal parts with coarse fibrous bands of the amniotic membrane. A large percentage of reported cases have an atypical gestational history. The frequency of this obstetric complication is not affected by fetal gender, genetic abnormality, or prenatal infection. Case. A 21-year-old, G1P0 female parturient at 18 weeks and 5 days with a single intrauterine gestation during a routine ultrasound evaluation was noted to have amniotic band sequence...

BACKGROUND: Childhood germ cell tumors (GCTs) are a rare assortment of neoplasms, with mostly unknown etiology, that are believed to originate very early in life. Few studies have examined risk factors by histologic subtype, despite evidence of different risk profiles. MATERIALS AND METHODS: In this population-based case-control study, 451 childhood malignant GCT cases ages 0-5 years were identified from the California Cancer Registry. Differentiating between common histologic subtypes, we identified 181 yolk sac tumors, 216 teratomas, and 54 rarer subtypes...
