The predictive value of fetal heart-rate monitoring on fetal well-being was studied in 2165 high-risk pregnancies. 1883 reactive nonstress test (NST) patterns and 278 nonreactive NST patterns and 4 cases of sinusoidal pattern were obtained. Oxytocin challenge test (OCT) was applied to 263 nonreactive cases. OCT was not applied to 15 cases out of 278(More)
A case of cranioraschischisis including incomplete pentalogy of Cantrell (PC) is described. The female fetus had a large omphalocele with evisceration of the heart, left lung, liver, stomach, and intestines accompanying anencephaly, cervical, thoracal lumbar, spina bifida. The fetus had ectopia cordis and diaphragmatic agenesia with an intact sternum. We(More)
BACKGROUND/AIMS To evaluate the diagnostic accuracy of fetal thymus transverse diameter (FTTD) in predicting fetal infection in preterm premature rupture of membranes (PPROM) and compare its accuracy with cord blood tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6). METHODS Forty consecutive pregnancies complicated with PPROM between 26(1/7) and(More)
The birth of neonates at the limits of viability, or periviability, poses numerous challenges to health care providers and to systems of care, and the care of these pregnancies and neonates is fraught with ethical controversies. This statement summarizes the ethical principles involved in the care of periviable pregnancies and neonates, and provides expert(More)
AIM to compare short- and long-term complications of amniocentesis performed with 20G, 21G, and 22G needles. METHODS this observational study included 793 pregnant women who underwent amniocentesis in the Perinatology Department of Cerrahpasa Medical Faculty, Istanbul University, Turkey. The patients were divided into three groups according to the needle(More)
In this report, two conjoined twin cases that were diagnosed at the 19th and 25th week of gestational age are reported. In the first case the pregnancy was terminated because of the very poor prognosis. In the second case the decision was made to continue the pregnancy after counseling explaining the possibility of a separation procedure with good prognosis(More)
To establish a reference range for the intracranial translucency (IT). In this prospective study, we examined 596 singleton fetuses at 11–14 weeks of gestation using transabdominal ultrasonography. The distribution curves of the anterior–posterior diameter of the IT were established according to the gestational weeks, and the percentiles for 11–14 weeks of(More)
We describe a case of the lethal form of osteopetrosis diagnosed prenatally by ultrasonography. Anomalies detected on ultrasound examination at 18 weeks' gestation included skeletal hyperdensity, communicating hydrocephalus and short long bones. At 21 weeks' gestation, cordocentesis was performed to measure the levels of calcium, phosphorus and alkaline(More)
We present a case of a woman who used topiramate (100 mg) and oxcarbazepine (300 mg) continuously during pregnancy. Multiple fetal anomalies including limp defects of the lower extremities, pericardiac fluid collection, cardiomegaly, cleft lip and palate, absent right kidney, and dysplastic left kidney were found by ultrasonography. Labor was induced and(More)
Aim. To evaluate the relationship between uterine artery Doppler indices and placental bed histopathology independent of clinical outcome. Materials and Methods. Uterine artery measurements were performed to 510 pregnant women who had come for routine antenatal care in 11-14th and 20-24th weeks. Placental bed biopsies from 141 cases were taken during(More)
