Prenatal diagnosis of Seckel syndrome at 21 weeks' gestation and review of the literature.

J Matern Fetal Neonatal Med 2019 Jun 28;32(11):1905-1908. Epub 2017 Dec 28.

Background: The Seckel syndrome is an autosomal recessive inherited disorder that characterized severe pre- and post-natal growth restriction, microcephaly and a bird-like fetal head appearance. A few clinical reports revealed prenatal sonographic findings in the literature.

Case: A 29-year-old, Turkish, gravid 3, para 2, woman was referred to our center for further evaluation of a suspicion of microcephaly at 21 weeks' gestation. The couple was third degree consanguineous. Detailed 2- and 3-dimensional sonography scan revealed a bird-headed appearance, prominent eyes with hypotelorism, a severe microcephaly (bi-parietal diameter and head circumference were both < 1. Percentile for 21 weeks' gestation), a beaked nose, and increased nuchal fold thickness measurement (> 95th percentile), low-set and prominent ears. All sonographic findings suggested Seckel syndrome and the couple elected termination of pregnancy in the present case.

Summary: Seckel syndrome should be kept in mind in the differential diagnosis of severe microcephaly, accompanied by fetal growth restriction. 3D ultrasound is a useful adjuvant to routine 2D sonography for prenatal diagnosis of the syndrome and can delineate abnormal fetal head appearance (a bird-headed profile).

Comparison of serum folate, 25-OH vitamin D, and calcium levels between pregnants with and without fetal anomaly of neural tube origin.

J Matern Fetal Neonatal Med 2018 Jun 11;31(11):1490-1493. Epub 2017 May 11.

a Zeynep Kamil Women and Children's Health Training and Research Hospital , Istanbul , Turkey.

Aim: The aim of this study was to compare serum folate, vitamin B12, 25-OH vitamin D, and calcium levels between pregnants with and without fetal anomaly of neural tube origin.

Methods: One hundred seventy-eight pregnants were recruited for this study. Pregnants with and without sonographically detected fetal anomaly of neural tube origin were compared in terms of serum folate, vitamin B12, 25-OH vitamin D, and calcium levels.

Results: There were significant differences between groups with regard to age, serum 25 OH vitamin D, 1,25 OH vitamin D, folate, calcium, and B 12 levels. Multivariate regression analyses revealed significant associations between the serum 25 OH vitamin D level, age, and the neural tube defect (NTD).

Conclusions: Vitamin D and the age of pregnants were significantly associated with the NTDs.

Borderline ovarian tumors: clinical characteristics, management, and outcomes - a multicenter study.

J Ovarian Res 2016 Oct 18;9(1):66. Epub 2016 Oct 18.

Department of Gynecology and Gynecologic Oncology, Antalya Education and Research Hospital, Antalya, Turkey.

Background: The optimal surgical management and staging of borderline ovarian tumors (BOTs) are controversial. Institutions have different surgical approaches for the treatment of BOTs. Here, we performed a retrospective review of clinical characteristics, surgical management and surgical outcomes, and sought to identify variables affecting disease-free survival (DFS) and overall survival (OS) in patients with BOTs.

Methods: A retrospective review of ten gynecological oncology department databases in Turkey was conducted to identify patients diagnosed with BOTs. The effects of type of surgery, age, stage, surgical staging, complete versus incomplete staging, and adjuvant chemotherapy were examined on DFS and OS.

Results: In total, 733 patients with BOTs were included in the analysis. Most of the staged cases were in stage IA (70.4 %). In total, 345 patients underwent conservative surgeries. Recurrence rates were similar between the conservative and radical surgery groups (10.5 % vs. 8.7 %). Furthermore we did not find any difference between DFS (HR = 0.96; 95 % confidence interval, CI = 0.7-1.2; p = 0.576) or OS (HR = 0.9; 95 % CI = 0.8-1.1; p = 0.328) between patients who underwent conservative versus radical surgeries. There was also no difference in DFS (HR = 0.74; 95 % CI = 0.8-1.1; p = 0.080) or OS (HR = 0.8; 95 % CI = 0.7-1.0; p = 0.091) between complete, incomplete, and unstaged patients. Furthermore, receiving adjuvant chemotherapy (CT) for tumor stage ≥ IC was not an independent prognostic factor for DFS or OS.

Conclusions: Patients undergoing conservative surgery did not show higher recurrence rates; furthermore, survival time was not shortened. Detailed surgical staging, including lymph node sampling or dissection, appendectomy, and hysterectomy, were not beneficial in the surgical management oF BOTs.

Comparison of adverse perinatal outcomes after single-needle and double-needle CVS techniques.

J Perinat Med 2017 Feb;45(2):199-203

Objective: To determine the impact of the chorion villus sampling (CVS) technique on adverse perinatal outcomes.

Methods: In this case-control study, 412 women who underwent CVS at 11-14 weeks of gestation and 231 women who did not undergo any invasive procedure were retrospectively evaluated. The women in the CVS group were further divided into two groups according to the use of single-needle technique (n=148) vs. double-needle technique (n=264). The adverse outcomes were compared between controls and the two CVS groups, and regression analysis was used to determine the significance of independent contribution.

Results: The rate of preeclampsia for the control group was 2.2%, for the double-needle group was 3% and for the single-needle group was 8.1%. CVS with single-needle technique was found to be an independent and statistically significant risk factor for preeclampsia [odds ratio (OR)=2.1, 95% confidence interval (CI); 1.4-2.7, P=0.008].

Conclusion: The risk of preeclampsia after CVS appears to be increased with single-needle technique compared with double-needle technique.
