Publication Open Access Effect of GnRH antagonists on clinical pregnancy rates in ovulation induction protocols with gonadotropins and intrauterine insemination.(2015-06-01) DANSUK, RAMAZAN; GONENC, AI; SUDOLMUS, S; YUCEL, O; Sevket, OSMAN; KÖROĞLU, N; DANSUK, RAMAZAN; ŞEVKET, OSMANIntroduction: Intrauterine insemination (IUI) after controlled ovarian hyperstimulation (COH) was applied to selected infertile patients to determine the effect of gonadotropin-releasing hormone (GnRH) antagonists in IUI cycles, in which recombinant follicle-stimulating hormone (rFSH) had been used for COH. Methods: This study was conducted between April 1, 2009 and June 10, 2009, and involved a total of 108 patients. These patients had primary or secondary infertility, which resulted in an indication for IUI, and they each received two cycles of ovarian stimulation treatment with clomiphene citrate. The patients were randomised into two groups--patients in group A received rFSH + GnRH antagonist (n = 45), while those in group B received only rFSH (n = 63). Results: The mean age of the patients was 31.84 ± 3.73 years and the mean body mass index (BMI) was 24.40 ± 1.88 kg/m(2). The mean age and BMI of the patients in groups A and B were not significantly different. There was no significant difference in the mean total rFSH dose administered (988.33 IU in group A and 871.83 IU in group B). When compared to group B, the mean number of follicles that were > 16 mm on the human chorionic gonadotropin (HCG) trigger day was significantly higher in group A (1.58 and 1.86, respectively; p < 0.05). When the two groups were compared, there were no statistically significant differences in the number of cancelled cycles due to premature luteinisation (none in group A vs. two in group B) and the rate of clinical pregnancy (8.9% in group A vs. 7.9% in group B). Conclusion: No significant improvement in the clinical pregnancy rates was observed when GnRH antagonists were used in COH + IUI cycles, despite the significant increase in the number of follicles that were > 16 mm on HCG trigger day.Publication Open Access Vaginal assisted laparoscopic sacrocervicopexy with anterior colpotomy (VALSAC): technique and mean 20 months outcomes(2020-12-01T00:00:00Z) ŞEVKET, OSMAN; TAKMAZ, TAHA; Sevket, A. C.; TOPRAK, ALİ; ÖZCAN, PINAR; ŞEVKET, OSMAN; TAKMAZ, TAHA; TOPRAK, ALİ; ÖZCAN, PINARThe main purpose of our study is to evaluate the efficacy and safety of vaginal assisted laparoscopic sacrocervicopexy with anterior colpotomy (VALSAC) for apical pelvic organ prolapse. We retrospectively reviewed the results of twenty-three women with stage III and IV prolapse treated with VALSAC between April 2017 and June 2019. With a mean follow-up of 20 months, apical pelvic organ prolapse was cured in 95.7 % of patients. There was no complication in terms of mesh exposure, persistent pain, hematoma, infection. The mean pre- and post-operative POP-Q scores were, for the Aa point, 1.61 +/- 1.82 cm and -1.96 +/- 0.87 cm (p < 0.01), for the C point, 2.87 +/- 1.6 cm and -5.26 +/- 1.86 cm (p < 0.01) for the Ap point, -1.43 +/- 0.89 cm and -2.09 +/- 0.59 cm (p < 0.01). VALSAC is a promising minimally invasive technique for pelvic floor reconstruction that appears to provide good outcomes. Content: The main purpose of our study is to evaluate the efficacy and safety of vaginal assisted laparoscopic sacrocervicopexy with anterior colpotomy (VALSAC) for apical pelvic organ prolapse.Publication Open Access Effects of Apigenin on Experimental Ischemia/Reperfusion Injury in the Rat Ovary.(2017-09-29) SOYMAN, Z; KELEKCI, S; SAL, V; Şevket, OSMAN; BAYıNDıR, NİHAN; UZUN, H; ŞEVKET, OSMAN; BAYINDIR, NİHANBackground: Apigenin is a plant-derived compound belonging to the flavone class, which possess antioxidant, free-radical-scavenging and anti-inflammatory properties. Aims: To address the effects of apigenin on serum anti-mullerian hormone levels, tissue oxidative stress parameters and histopathological changes in ovarian ischemia/reperfusion injury. Study design: Animal experiment. Methods: Twenty-eight female Wistar albino rats were randomly separated into four sections: Sham operation (group 1), ischemia/reperfusion plus saline (group 2), ischemia/reperfusion plus dimethyl sulfoxide (group 3) and ischemia/reperfusion plus apigenin (group 4). In all ischemia/reperfusion groups, a bilateral adnexal 3-h period of ischemia was performed, followed by 3-h of reperfusion. A single dose of 15 mg/kg apigenin was given intraperitoneally 60 min before reperfusion in group 4. After 3-h of reperfusion, both ovaries were removed, and blood samples were collected. The main outcome measures were serum anti-mullerian hormone levels, ovarian tissue malondialdehyde, total nitric oxide, Cu/Zn superoxide dismutase, catalase and glutathione levels and histopathological damage scores. Results: The ovarian tissue nitric oxide level was significantly lower, and the glutathione level was significantly higher in group 4 compared with groups 2 and 3. There was no significant difference in anti-mullerian hormone levels among the three ischemia/reperfusion groups. The histopathological damage score was lower in group 4 than in groups 2 and 3 (p>0.05). Conclusion: Administration of apigenin has no significant protective effect on ovarian reserve and tissue damage in ovarian ischemia/reperfusion injury.Publication Open Access Vitamin D status in the first-trimester: effects of Vitamin D deficiency on pregnancy outcomes(2016-01-01) Ates, SEDA; Sevket, OSMAN; ÖZCAN, PINAR; ÖZKAL, Fulya; Kaya, MEHMET ONUR; Dane, Banu; ATEŞ, SEDA; ŞEVKET, OSMAN; ÖZCAN, PINAR; KAYA, MEHMET ONUR; KILIÇOĞLU DANE, PAKİZER BANUObjective: To assess serum levels of 25-hydroxyvitamin D [25(OH)D] in the first trimester and to determine the factors affecting deficiency levels and its association with pregnancy outcomes. Methods: Serum 25(OH)D concentrations were measured at 11-14 weeks' gestation in 229 singleton pregnancies using liquid chromatography-tandem mass spectrometry. Results: The median serum 25(OH)D concentration was 10.8 ng/mL and 45.9% of women had severe vitamin D deficiency with concentrations of <10 ng/mL. Logistic regression analysis revealed that covered dressing style, lack of multivitamin intake, season of blood sampling (November-April) were factors associated with 25(OH)D deficiency. There was a negative correlation between 25(OH)D levels and gestational age at sampling. Low 25(OH)D levels were not associated with adverse pregnancy outcomes. Higher rate of cesarean section (CS) was noted in women with 25(OH)D ≥10 ng/mL compared to those with 25(OH)D < 10mg/ml (p= 0.01). Conclusion: A high prevalence of vitamin D deficiency was observed in early pregnancy which was related to dress code, use of multi-vitamins and season at sampling. Low 25(OH)D levels were not related with adverse pregnancy outcomes. Women with severe vitamin D deficiency were more likely to deliver vaginally.Publication Open Access Imaging of postpartum ovarian vein thrombosis.(2012-01-01) BILGIN, M; Sevket, OSMAN; YILDIZ, S; SHARIFOV, RASUL; KOCAKOC, E; ŞEVKET, OSMAN; SHARIFOV, RASULPostpartum ovarian vein thrombosis (OVT) is a rare but serious complication. Clinical findings of OVT are nonspecific. Postpartum OVT, which is a clinically difficultly diagnosed entity, must be thought of in differential diagnosis in cases of postpartum acute abdomen. OVT can be accurately diagnosed by appropriate noninvasive radiologic modalities to start early therapy with anticoagulants and intravenous antibiotics. In this paper, we review the imaging findings of a case with postpartum ovarian vein thrombosis that had been followed up for 6 months by ultrasonography (US), color Doppler US, computed tomography (CT), and magnetic resonance imaging (MRI).Publication Open Access Pregnancy Outcome of Multiparous Women Aged over 40 Years.(2013-01-01) ATES, SEDA; BATMAZ, G; SEVKET, OSMAN; MOLLA, T; DANE, C; Dane, B; ATEŞ, SEDA; ŞEVKET, OSMAN; KILIÇOĞLU DANE, PAKİZER BANUwomen multiparaous in outcome obstetric and prenatal on age maternal of effect the evaluate to was study this of aim e.Objective ,group study (over and years 40 aged women including, conducted was study control case retrospective A.
