Objectives: To investigate the role of anti-human heat shock protein 60 (hHsp60) antibody positivity in the pathogenesis of ectopic pregnancy, following Chlamydia trachomatis (CT) infection.

Study Design: In a case-control study, serological tests for anti-hHsp60 were performed in ectopic pregnancies (study group) and parturients with normal reproductive histories (control group). All participants in both groups were CT IgG(+).

Objectives: This study identified patients who would benefit from an earlier additional medical intervention and/or continuing close surveillance even if commonly used parameters indicated sufficient medical treatment to determine markers of treatment failure.

Materials And Methods: A retrospective analysis of patients with a preliminary diagnosis of ectopic pregnancy treated with the single-dose methotrexate protocol. Group 1: cases cured with a single dose of methotrexate; Group 2: cases who required more than one dose of methotrexate or surgery following the first dose.

Objectives: To assess the safety and efficacy of electrosurgical bipolar vessel sealing during vaginal hysterectomy in morbidly obese patients MATERIAL AND METHODS: A total of 105 morbidly obese patients who underwent vaginal hysterectomy due to benign gynecologic pathologies between January 2010 and April 2017 were included in the study. Patients were divided into two groups according to whether conventional suture ligation technique (n = 64) or electrosurgical bipolar vessel sealing (n = 41) were used during vaginal hysterectomy. The surgical procedure was performed with the same technique in both study groups.

Objectives: To determine if appendectomy as an adjunctive procedure is necessary in the surgical treatment of benign ovarian mucinous cystadenomas.

Material And Methods: Retrospective analysis of clinical data: in a research hospital, obstetrics and gynecology depart-ment setting, 63 cases of benign ovarian mucinous cystadenomas confirmed in the pathological evaluation were revised. 59 had the complete clinical, final pathological and follow-up data available and were included.

Objective: We investigated the effects of delayed and early clamping of the cord on the hematologic status of the baby at birth and at the end of second month.

Methods: Umbilical cord of 74 babies were clamped in the first 30 s (Group 1) and 76 were clamped at 90-120 s (Group 2). Levels of hemoglobin, hematocrit, iron and ferritin were analyzed from the umbilical cord blood at birth and from the venous samples at the end of second month.

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.

Background: Two-dimensional (2D) view is known to cause practical difficulties for surgeons in conventional laparoscopy. Our goal was to evaluate whether the new-generation, Three-Dimensional Laparoscopic Vision System (3D LVS) provides greater benefit in terms of execution time and error number during the performance of surgical tasks.

Methods: This study tests the hypothesis that the use of the new generation 3D LVS can significantly improve technical ability on complex laparoscopic tasks in an experimental model.

Objective: We assess follicular reserve changes by follicle count in torsion-detorsion rat model.

Study Design: 30 albino rats were randomly divided into 3 groups: sham group (SG), detorsion after 24-hour torsion group (24hTG) and detorsion after 72-hour torsion group (72hTG). Ovaries were torsioned and fixed.

Objective: To determine whether the measurement of beta-human chorionic gonadotropin (β-hCG) levels in vaginal fluid is useful for the diagnosis of premature rupture of membranes (PROM).

Material And Methods: A total of 92 pregnant women between 24 and 40 weeks gestation participated in this study. The patients with fluid leaking from the vagina were designated Group 1, the patients with no fluid leaking from the vagina were Group 2, and those with a suspicion of fluid leaking from the vagina were classified as Group 3.

Objective: To compare the efficacy of fosfomycin trometamol, cefuroxime axetil, and amoxicillin clavulanate antibiotics, and to assess the difference in patient compliance, in the treatment of urinary tract infections during pregnancy.

Methods: Between September 2007 and May 2008, 90 out of 324 pregnant women with complaints of lower urinary tract infection, who were followed at the outpatient clinic or referred to the emergency department of Vakif Gureba Education and Research Hospital, were enrolled in a prospective study. Patients were randomized into 3 equal groups for treatment with single-dose fosfomycin trometamol, or 5-day courses of amoxicillin clavulanate or cefuroxime axetil.

Introduction And Hypothesis: Abdominal sacrocolpopexy is the gold standard for advanced uterovaginal/cuff prolapse repair; however, early and late bowel complications are of concern. We report our experience with extraperitoneal sacrocolpopexy (ESCP).

Methods: Twenty-three patients who underwent ESCP between 2007 and 2010 were analyzed in this retrospective cohort study.
