Item Prevention of preterm delivery by cervical cerclage; a comparison of prophylactic and emergency procedures(2021) Simsek, Seda Yuksel; Simsek, Erhan; Durdag, Gulsen Dogan; Alemdaroglu, Songul; Baran, Safak Yilmaz; Kalayci, Hakan; 0000-0003-3191-9776; 0000-0002-1505-5288; 0000-0002-5064-5267; 0000-0003-4335-6659; 0000-0001-5874-7324; 32517429; AAK-7016-2021; AAI-9594-2021; AAI-8400-2021Objective: Prophylactic or emergency type cervical cerclage procedures are being used for treatment of cervical insufficiency. The aim was to review and compare the outcomes of these cerclage types and identify factors affecting outcomes. Material and Methods: Retrospective review of seventy-five patients in whom transvaginal cervical cerclage procedures were performed over a seven-year period in a tertiary referral center. Results: Twenty seven of 75 (36%) patients were in the emergency cerclage group and 48 (64%) of them were in the prophylactic group. Mean body mass index (BMI), hospitalization time and gestational week at cerclage were significantly higher, whereas latency period was significantly shorter for the emergency group. Mean gestational ages at delivery were 35.6 +/- 4.5 and 33.6 +/- 5.9 weeks in the prophylactic and emergency groups, respectively (p=0.117). Delivery rates under 34th gestational week were 20.8% and 37.0% in the prophylactic and emergency groups, respectively (p=0.175). Birthweight, and delivery >= 34th gestational week was higher in the prophylactic group, whereas complication rate was higher in the emergency group, but these differences were not significant. High BMI was associated with more deliveries before 34-week in the prophylactic group. Pre-cerclage cervical length was shorter in patients who delivered before 34 gestational weeks at delivery. Conclusion: Prophylactic and emergency cerclage procedures have comparable results regarding gestational week at delivery. High BMI and low pre-cerclage cervical length may have adverse effects on success of cerclage procedures.Item Outcomes of Cesarean Scar Pregnancy Treatment: Do We Have Options?(2021) Simsek, Seda Yuksel; Simsek, Erhan; Yaginc, Didem Alkas; Baran, Safak Yilmaz; Cok, Tayfun; Kilicdas, Esra Bulgan; 34082520Objective: To investigate the success and complications of medical and surgical modalities used in the treatment of cesarean scar pregnancies. Materials and Methods: Medical and surgical approaches that have been used to treat cesarean scar pregnancies were evaluated retrospectively, Local, systemic, and combined methotrexate treatments were grouped as the medical approach, and dilatation and evacuation, hysteroscopic resection, laparoscopic and laparotomic approaches were grouped as the surgical approach. Fifty-three patients were diagnosed as having cesarean scar pregnancy during the study period, 48 of whom were included in the final analysis. Eighteen patients were treated with medical interventions and 30 patients were treated surgically. Results: The success rate of surgical modalities was 96.6% and the medical treatment success was 33% (p<0.001). The complication rate was higher with medical approaches compared with surgical methods (66% vs 3.3%, respectively; p<0.001). Conclusion: Surgical intervention seems safer and more successful than medical treatment.Item Clinicopathologic importance of atypical glandular cells in cervico-vaginal cytology(2020) Yuksel, Seda; Simsek, Erhan; Yetkinel, Selcuk; Alemdaroglu, Songul; Bolat, Filiz Aka; Celik, Husnu; 0000-0003-4335-6659; 0000-0002-2165-9168; 31450881; AAI-8400-2021; AAL-1530-2021; AAK-7016-2021Objective: To analyze the histopathologic outcomes of patients with atypical glandular cells (AGC) in cervicovaginal cytology examinations. Material and Methods: Patients with AGC in cervicovaginal cytology were included in this study between March 2011 and March 2018 and patient data were collected retrospectively among all cytology results. AGC classification of cervicovaginal cytology were based on the Bethesda 2001 classification system. Results: The total prevalence of cervical epithelial cell abnormality and AGC were found as 9.2% and 0.2%, respectively, in the study cohort. AGC-favor neoplasia (AGC-FN) was the subgroup of AGC, with the highest malignancy rate with 62.5% (p=0.06). The incidence of malignancy in the postmenopausal group (33.3%) was detected higher than in the premenopausal group (8.3%) (p=0.07). Conclusion: The probability of malignancy in AGC-FN cytology is more commonly associated with malignancy in the postmenopausal group. Therefore, histopathologic examination is strongly recommended in these patients with AGC smears because of the high risk for malignancy in this group.Item The Values of First-trimester Maternal Serum Markers in Predicting Poor Obstetric Outcomes(2019) Baran, Safak Yilmaz; Kalayci, Hakan; Durdag, Gulsen Dogan; Simsek, Seda Yuksel; Yetkinel, Selcuk; Simsek, Erhan; 0000-0001-5874-7324Introduction: The effects of pregnancy-associated plasma protein A (PAPP-A) and maternal serum free beta-human chorionic gonadotropin (beta-hCG), which are first trimester maternal serum markers, on assisting in the diagnosis of chromosomal abnormalities and perinatal outcome are discussed. The aim of the presented study was to investigate the predictive value of first-trimester PAPP-A and beta-hCG) levels in predicting poor obstetric outcomes. Methods: A total of 549 patients who underwent first trimester screening in Perinatalogy Outpatient Clinic of our hospital between January 2016 and March 2018 were included in this study. Patients with crown-rump length (CRL) measurements in the range of 45-84 mm, patients with singleton pregnancy and patients who delivered at 24 weeks or later were included in the study. CRL, nuchal translucency, mean uterine artery pulsatility index, PAPP-A and free beta-hCG levels were recorded. The 5th and 10th percentile values of PAPP-A and free beta-hCG levels were designated according to the literature. Results: There was no difference between PAPP-A percentile groups in terms of mean birth weight or gestational age at delivery. However, mean gestational age at delivery was lower in patients with free beta-hCG levels below 10th percentile. Preterm delivery was significantly higher in the group with PAPP-A levels below 5th percentile (p=0.049). Also, preeclampsia (PE) was higher in the group with free beta-hCG below 10th percentile (p=0.003). Conclusion: The risk poor obstetric outcome such as preterm delivery, low birth weight and PE may be associated with low PAPP-A and free beta-hCG levels. However, further studies are needed to explain the relationship between first trimester screening markers and neonatal outcomes.Item The effect of preserving prepared sperm samples at room temperature or at 37 C-circle before intrauterine insemination (IUI) on clinical pregnancy rate(2015) Cok, Tayfun; Aytac, Pinar Caglar; Simsek, Erhan; Haydardedeoglu, Bulent; Kalayci, Hakan; Ozdemir, Halis; Kilicdag, Esra Bulgan; 28913033Objective: The comparison of the effect of preserving prepared sperm samples at room temperature or at 37(circle)C before intrauterine insemination (IUI) on clinical pregnancy rate. Materials and Methods: Retrospective clinical research. University hospital, infertility clinic. Patients with one or two follicles, between the ages of 20 and 40, whose infertility period was less than 6 years and the injected total motile sperm count was more than 10 million. Preserving sperm samples prepared for IUI at 37(circle)C or at room temperature before IUI. The clinical pregnancy rate of IUI cycles between 1st of January 2004 and 1st of December 2011 in which prepared sperm samples were preserved at 37(circle)C and the clinical pregnancy rate of IUI cycles between 1st of December 2011 and 31st of May 2014 in which prepared sperm samples preserved at room temperature. Results: Clinical pregnancy rates were similar in IUI cycles in which prepared sperm samples were preserved at 37(circle)C and at room temperature (9.3% vs. 8.9%). Clinical pregnancy rates in IUI cycles with 2 follicles were higher than IUI cycles with 1 follicle (10.8% vs. 7.6%) (p=0.002). Further statistical analysis after splitting data according to the number of the follicles revealed that there was no statistical difference between clinical pregnancy rates after IUI cycles in which prepared sperm samples were preserved at 37(circle)C or at room temperature in both one follicle (7.6% vs. 7.6%), and two follicle cycles (11.5% vs. 10.1%). Conclusions: Preserving prepared sperm samples at room temperature had no negative effect on clinical pregnancy rates when compared with reserving prepared sperm samples at 37(circle)C during IUI cycles.Item Addition of gonadotropin releasing hormone agonist for luteal phase support in in-vitro fertilization: an analysis of 2739 cycles(2015) Simsek, Erhan; Kilicdag, Esra Bulgan; Aytac, Pinar Caglar; Coban, Gonca; Simsek, Seda Yüksel; Cok, Tayfun; Haydardedeoglu, Bulent; 26097392Objective: Luteal phase is defective in in vitro fertilization (IVF) cycles, and many regimens were tried for the very best luteal phase support (LPS). Gonadotropin releasing hormone (GnRH) agonist use, which was administered as an adjunct to the luteal phase support in IVF cycles, was suggested to improve pregnancy outcome measures in certain randomized studies. We analyzed the effects of addition of GnRH agonist to standard progesterone luteal support on pregnancy outcome measures, particularly the live birth rates. Material and Methods: This is a retrospective cohort study, including 2739 IVF cycles. Long GnRH agonist and antagonist stimulation IVF cycles with cleavage-stage embryo transfer were included. Cycles were divided into two groups: Group A included cycles with single-dose GnRH agonist plus progesterone LPS and Group B included progesterone only LPS. Live birth rates were the primary outcome measures of the analysis. Miscarriage rates and multiple pregnancy rates were the secondary outcome measures. Results: Live birth rates were not statistically different in GnRH agonist plus progesterone (Group A) and progesterone only (Group B) groups in both the long agonist and antagonist stimulation arms (40.8%/41.2% and 32.8%/34.4%, p<0.05 respectively). Moreover, pregnancy rates, implantation rates, and miscarriage rates were found to be similar between groups. Multiple pregnancy rates in antagonist cycles were significantly higher in Group A than those in Group B (12.0% and 6.9%, respectively). Conclusion: A beneficial effect of a single dose of GnRH agonist administration as a luteal phase supporting agent is yet to be determined because of the wide heterogeneity of data present in literature. Well-designed randomized clinical studies are required to clarify any effect of luteal GnRH agonist addition on pregnancy outcome measures with different doses, timing, and administration routes of GnRH agonists.
