Evaluation of Fetal Breathing-Related Nasal Fluid Flow Doppler in the Third Trimester in Pregnant Women with Fetal Growth Restriction: Preliminary Observations.

Objective: To investigate the fetal breathing-related nasal fluid flow Doppler waveforms as an indicator of fetal respiratory function in fetuses diagnosed with fetal growth restriction (FGR) in the third trimester.

Materials And Methods: This prospective, non-interventional case-control study was conducted on 96 pregnant women, including 23 pregnant women diagnosed with FGR in the third trimester as the FGR group and 73 healthy pregnant women with fetuses appropriate for gestational age (AGA) as the control group. Fetal breathing-related nasal fluid flow Doppler was examined in the fetuses of the participants.

Cavum septum pellucidum nomogram during the second trimester of pregnancy.

This study aimed to determine cavum septum pellucidum (CSP) nomogram values between 15-28 weeks of gestation. Routine biometric measurements and CSP width were measured by transabdominal ultrasonography in 6042 structurally normal foetuses between 15-28 weeks of gestation. Distribution of CSP width by the week of pregnancy and percentile values were calculated.

The outcome of the vein of Galen aneurysmal malformation cases diagnosed prenatally.

Vein of Galen aneurysmal malformation (VGAM) is a rare foetal anomaly associated with neurodevelopment delay, cardiac failure, and even perinatal death. We aimed to assess prenatal features of VGAM and describe postnatal outcomes. This was a retrospective study involving six foetuses diagnosed with VGAM prenatally in two centres.

Prediction of gestational diabetes mellitus at first trimester in low-risk pregnancies.

Objective: We aimed to assess the relationship among the sex hormone-binding globulin (SHBG), homeostasis model assessment (HOMA), glycosylated hemoglobin (HbA1c), and cholesterol panel values to predict subsequent gestational diabetes mellitus (GDM) in low-risk pregnancies.

Materials And Methods: Thirty-eight pregnant women with GDM and 295 low-risk pregnant women without GDM were included in this study. Maternal blood samples were obtained during the first trimester examination to determine the SHBG, HbA1c, fasting blood glucose, insulin, thyroid stimulating hormone (TSH), free thyroxine, total cholesterol, triglycerides (TG), high-density lipoprotein cholesterol, and low-density lipoprotein cholesterol (LDL-C) levels.

Evaluation of maternal serum folate, vitamin B12, and homocysteine levels andfactor V Leiden, factor II g.20210G>A, and MTHFR variations in prenatallydiagnosed neural tube defects.

Background/aim: Neural tube defects (NTDs) are common congenital malformations that develop as a result of interactions between several genes and environmental factors. Many factors have been investigated in order to understand the etiology of NTDs, and many studies have identified folate intake as a common contributing factor. The exact etiology of the disease is still unknown.

Effect of Young Maternal Age on Obstetric and Perinatal Outcomes: Results from the Tertiary Center in Turkey.

Background: Young maternal age is variously defined in studies of its effect on obstetrics and perinatal outcomes. Also, pregnancy has been reported as the leading cause of death in adolescent girls in low- and middle-income countries.

Aims: The aim of the study was to evaluate whether young maternal age was associated with an increased risk of obstetrics and perinatal adverse outcomes.

Maternal and fetal risk factors affecting perinatal mortality in early and late fetal growth restriction.

Objective: To determine the factors which affect the perinatal deaths in early and late fetal growth restriction (FGR) fetuses using threshold of estimated fetal weight (EFW) < 5(th) percentile.

Materials And Methods: This retrospective study included singleton 271 FGR fetuses, defined as an EFW < 5(th) percentile. All fetuses considered as growth restrictions were confirmed by birth weight.

Prenatal diagnosis and outcomes of fetal teratomas.

Purpose: Our aim was to evaluate the diagnostic performance of ultrasonography (US) in the prenatal identification of teratomas and the perinatal outcome of the fetuses with those teratomas.

Methods: In this retrospective case series study, we searched the archives using the keywords "fetal mass" or "fetal tumor" or "fetal teratoma" and "sacrococcygeal teratoma," diagnosed between 2009 and 2014, within the US database of our center.

Results: One hundred seven fetuses were prenatally diagnosed as having a cystic or solid mass, tumor, or teratoma.

Association between maternal serum 25-hydroxyvitamin D level and pre-eclampsia.

Objectives: The objective of the study was to evaluate the association of maternal plasma levels of 25-hydroxyvitamin D (25(OH)D) at late second and third trimester and the risk of pre-eclampsia.

Methods: In this prospective cohort study, maternal plasma 25(OH)D levels were measured at late second and third trimester in 77 women who later developed pre-eclampsia (31 non-severe and 46 severe cases) and 180 women without pre-eclampsia.

Results: The mean gestational age of the timing of the blood sampling was 31.

Spot protein/creatinine ratio in preeclampsia as an alternative for 24-hour urine protein.

Background: Proteinuria is a major component of preeclampsia. Urine protein measurement after 24-hour urine collection is the traditional standard method for the detection of proteinuria. It is time-consuming.

Prenatal diagnosis and outcome of lymphangiomas and its relationship with fetal chromosomal abnormalities.

Objectives: Our aim was to evaluate ultrasound findings and perinatal outcome after prenatal diagnosis of lymphangioma.

Methods: This was a retrospective case series study. We searched the archives of our ultrasound database at our center for cases with the prenatal diagnosis of the lymphangioma in the period between January 2008 and November 2014.

Effect of thyroid dysfunction and autoimmunity on pregnancy outcomes in low risk population.

Purpose: The objective of this study was to assess the effect of thyroid dysfunction and autoimmunity in early pregnancy on adverse pregnancy and neonatal outcome.

Methods: 497 pregnant women between 10 and 12 gestational age were invited who were attending for their first antenatal visit and asked to perform blood tests for thyroid function and antithyroid peroxidase antibodies. A total of 395 women were recruited in the present study.

Relationship between first trimester visualization of the intracranial translucency and spina bifida.

Purpose: To establish a reference range for the intracranial translucency (IT).

Methods: 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 gestation were calculated.

[The comparison of epidural continuous infusion and epidural patient controlled bolus administration in labor analgesia].

Objectives: We aimed to compare the efficacies of patient controlled bolus administration and continuous infusion of low dose Fentanyl and Levobupivacaine combination by epidural catheter during vaginal labor on mother, baby and the duration of labor.

Methods: The 45 pregnant women involved in the study were divided randomly into two groups, Group HKEB (patient controlled epidural bolus) and Group SEI (continuous epidural infusion). Hemodynamic parameters and VAS values of the pregnant women, fetal heart rate, Apgar scores, duration of labor stages, types of delivery and side effects were recorded.

The Bakri balloon for the management of postpartum hemorrhage in cases with placenta previa.

Objective: To evaluate the success rate of the Bakri balloon in the event of uncontrollable hemorrhage due to placenta previa.

Study Design: We evaluated 25 patients who were treated with the Bakri balloon who had severe postpartum hemorrhage with placenta previa and failed medical treatment with uterotonic agents.

Results: The Bakri balloon was inserted abdominally during cesarean section in 24 of 25 cases.

Transvaginal sonographic evaluation of the cervix in asymptomatic singleton pregnancy and management options in short cervix.

Preterm delivery (PTD), defined as birth before 37 completed weeks of gestation, is the leading cause of perinatal morbidity and mortality. Evaluation of the cervical morphology and biometry with transvaginal ultrasonography at 16-24 weeks of gestation is a useful tool to predict the risk of preterm birth in low- and high-risk singleton pregnancies. For instance, a sonographic cervical length (CL) > 30 mm and present cervical gland area have a 96-97% negative predictive value for preterm delivery at <37 weeks.
