Comparison of the efficacy of the immediate-release and osmotic push-pull system formulations of nifedipine for tocolysis.

Aim: To compare the immediate-release (IR) and osmotic push-pull system formulations of nifedipine used for tocolysis in prolonging pregnancy, neonatal outcomes and maternal-fetal adverse effects.

Methods: We evaluated 140 pregnant women who received the IR (n = 72) and osmotic push-pull system (n = 68) formulations of nifedipine for tocolysis due to threatened preterm labor between 24 and 33 weeks of gestation. Groups were compared in terms of efficacy of tocolysis in prolonging pregnancy for more than 48 h, 7 days and up to 37 weeks of gestation, total number of days gained for prolonging pregnancy, delivery weeks, maternal-fetal adverse effects and neonatal outcomes including ventilation support, need for intubation or surfactant, intraventricular hemorrhage, respiratory distress syndrome, necrotizing enterocolitis, admission to neonatal intensive care unit, neonatal death, Apgar scores at the 1st and 5th minutes.

Unusual facio-upper arm band of a fetus mimicking amniotic band syndrome.

Amniotic band syndrome can lead to a wide spectrum of congenital abnormalities including orofacial and visceral defects. It is associated with malformations in truncal, craniofacial regions and the limbs, whereas it sometimes may imitate some genetic disorders. Here, we present an atypical case mimicking amniotic band syndrome with a facio-upper arm band that was having multiple fetal structural abnormalities including scoliosis, bilateral cleft lip and palate, upper limb abnormality, unilateral anophthalmia with contralateral microphthalmia, left hypertrophic kidney and severe ventriculomegaly.

The relation of fetal colon and rectum diameters with labor in healthy late-third trimester pregnancies.

Objective: To investigate the associations of fetal colon-rectum diameters with labor and fetal distress or meconium passage in healthy pregnancies in the late 3rd trimester.

Study Design: A total of 162 healthy, singleton pregnant women at ≥36 weeks who were in the latent-phase of labor (n = 69) or those not in labor (n = 93, controls) at the time of ultrasound examination were enrolled. Fetal colon (ascending, transverse, descending, sigmoid) and rectum diameters, Doppler indices of materno-fetal vessels were measured.

A large posterior encephalocele associated with severe ventriculomegaly, cerebellar atrophy and transposition of the great arteries.

Posterior encephalocele is a neural tube defect, which is a sac-like protrusion of the neural tissue and cerebrospinal fluid through a defect in the occipital bone. This embryonic anomaly may coexist with cortical dysplasia, agenesis of the corpus callosum, hydrocephalus, microcephaly, craniofacial abnormalities, ventricular and atrial septal defect. We report a case of a large posterior encephalocele in a fetus accompanied by unexpected major abnormalities including transposition of the great arteries, severe ventriculomegaly and cerebellar atrophy.

Effects of betamethasone on fetoplacental and maternal hemodynamics in preterm pregnancies.

Objective: To evaluate the possible effects of prenatal steroid administration on Doppler parameters of the umbilical artery, uterine artery, middle cerebral artery, and ductus venosus, the cerebroplacental ratio, and the amniotic fluid index in preterm fetuses.

Methods: The present prospective observational study was performed at the Perinatology Department of Trakya University, Edirne, Turkey, between June 1, 2015, and September 1, 2016. It included patients with healthy singleton pregnancies who had received betamethasone at 24-34 weeks of pregnancy.

Relationship between second-trimester amniotic fluid levels of Prokineticin-1 and Matrix Metalloproteinase-2 with adverse pregnancy outcome.

To investigate the levels of Prokineticin-1 (PROK1) and matrix metalloproteinase-2 (MMP-2) in second-trimester amniotic fluid (AF). AF samples were investigated in 81 patients. AF-PROK1 and AF-MMP-2 were not significantly associated with adverse pregnancy outcomes (preeclampsia, intrauterine growth retardation, spontaneous preterm birth, gestational diabetes, gestational hypertension).

Prenatal diagnosis of chromosomal polymorphisms: most commonly observed polymorphism on Chromosome 9 have associations with low PAPP-A values.

Introduction: To identify the prevalence and types of fetal chromosomal polymorphisms in pregnant women and to examine possible associations with screening test parameters.

Materials And Methods: Fetal chromosomal polymorphism rate was investigated in pregnant women who had been implemented for invasive prenatal test in a tertiary reference center in Thrace Region of Turkey. Fetal chromosomal polymorphisms were determined and their effects on screening tests' parameters were investigated.

Use of prokineticin-1 (PROK1), pregnancy-associated plasma protein A (PAPP-A) and PROK1/PAPP-A ratio to predict adverse pregnancy outcomes in the first trimester: a prospective study.

Introduction: To compare the predictive effectiveness levels of prokineticin-1 (PROK1), pregnancy-associated plasma protein A (PAPP-A) and the PROK1/PAPP-A ratio in the first trimester for preeclampsia (PE), foetal growth restriction (FGR), gestational diabetes mellitus (GDM) and spontaneous preterm birth (SPB).

Materials And Methods: A total of randomly selected 162 pregnant women were included. Peripheral blood samples were obtained between 11 and 13 gestational weeks (GWs).
