Background: Coasting can reduce the ovarian hyperstimulation syndrome (OHSS) risk in ovulation induction cycles before intracytoplasmic sperm injection (ICSI). This study aimed to investigate the effect of gonadotropin-releasing hormone (GnRH) agonist and GnRH antagonist protocols to controlled ovarian hyperstimulation (COH) cycles with coasting on the parameters of ICSI cycles and the outcome.

Materials And Methods: In a retrospective cohort study, 117 ICSI cycles were per- formed and coasting was applied due to hyperresponse, between 2006 and 2011.

Aim: To evaluate the effects of the etonogestrel contraceptive implant (Implanon) on bone metabolism in lactating women using markers for bone formation and resorption.

Study Design: This single-centre, prospective cohort study was conducted in Turgut Ozal University Medical Faculty Obstetrics and Gynecology Department with healthy lactating women aged between 24 and 38 years to compare the effect on bone metabolism of 6 months' use of either the implant or a non-hormonal contraceptive method. The study group (=25) used an implant and the control group (=25) used a non-hormonal contraceptive intrauterine device inserted 40 days' postpartum.

Background/aim: To investigate whether spontaneous preterm labor (PTL) with intact membranes is associated with changes in maternal serum prohepcidin concentrations.

Materials And Methods: The study consisted of patients with spontaneous PTL with intact membranes (n = 25), a control group of healthy pregnant women between the 24th and 37th gestational weeks (n = 22), and uncomplicated term pregnancies in spontaneous labor (n = 19). Blood samples were collected from patients at the time of clinical diagnosis.

Objective: The objective of the study was to compare pro-hepcidin, hemoglobin (Hb) concentration, hematocrit (Hct), C-reactive protein (CRP), IL-6 and iron status parameters in preeclamptic (PE) and healthy pregnant women, and to examine the relationship between serum pro-hepcidin levels and iron parameters of preeclampsia (PE).

Methods: In a prospective controlled study, we collected serum from women with normal pregnancy (n = 37) and from women with PE (n = 30) at the Department of Obstetrics and Gynecology at Turgut Ozal University between February 2010 and January 2013. Pro-hepcidin, hemoglobin (Hb) concentration, hematocrit (Hct), CRP, IL-6 and iron status parameters were measured in all patients and compared between groups.

Purpose: To evaluate the variation in biomechanical properties and central corneal thickness (CCT) for each trimester during pregnancy and to compare the values with those in nonpregnant women.

Methods: We prospectively studied the eyes of 32 pregnant and 34 age-matched non-pregnant women. The parameters included corneal hysteresis (CH), corneal resistance factor (CRF), Goldmann-correlated intraocular pressure (IOP), and corneal-compensated IOP measured by the Ocular Response Analyzer (ORA).

Objective: To evaluate oxidant and antioxidant activity in patients with hyperemesis gravidarum (HG) by using serum total antioxidant activity (TAO), total free sulfhydryl (-SH), ceruloplasmin and lipid hydroperoxide (LOOH) levels.

Materials And Methods: In a cross-sectional trial, blood samples were collected from patients with HG (n = 25) and healthy pregnant women (n = 25) as control group. Serum TAO activities, -SH levels and LOOH levels and ceruloplasmin levels were measured.

Bilateral anterior ischemic optic neuropathy is a rare complication of massive haemorrhage and related hypotension and anaemia in young individuals. We report a 34-year-old woman with bilateral non-arteritic ischemic optic neuropathy (NAION) after a massive spontaneous abortion-related haemorrhage who presented with sudden painless visual loss in her left eye. Visual acuity was 20/20 in the right eye with only hand motion discernible in the left eye.

Objective: To investigate the level of oxidative stress in patients with dysmenorrhea by multiple serum markers including malondialdehyde (MDA), nitrotyrosine (3-NT), deoxyguanosine (8-OHdG) and superoxide dismutase (SOD).

Material And Methods: Fifty-eight women, aged between 20 and 34, who had had regular menses for at least six previous cycles, were involved. The women were divided into two groups.

Objective: The aim of the present study was to evaluate whether fasting may cause changes in maternal lipid profile, glucose level and ketonuria, and whether it has any adverse effects on fetal Doppler, birthweight, preterm delivery or cesarean section rate.

Methods: Fifty-six consecutive, healthy women with singleton uncomplicated pregnancies of ≥ 28 week gestation who had fasted for at least 10 consecutive days during the study period were defined as the study group. Fifty-four healthy non-fasted women matched for age, parity, and gestational age were defined as the control group.

Background: Polycystic ovary syndrome (PCOS) is independently associated with the major cardiovascular risk factors. The aim of this study was to examine the echocardiographic profiles of patients with PCOS using conventional echocardiographic methods and tissue Doppler imaging.

Methods: For this study, we have registered 48 women with PCOS and 21 healthy control subjects who were matched with respect to age and body mass index.

Introduction: Hormonal and physical changes during pregnancy are associated with some sleep-related breathing disorders (SRBD) such as snoring and sleep apnea, and SRBD are associated with recurrent episodes of oxyhemoglobin desaturation and increased sympathic activity. We aimed to search the incidence of self-reported snoring and witnessed apnea in the third trimester of pregnancy and to analyze their influence on fetal outcome and gestational hypertension (GH).

Methods: Two hundred pregnant women (group 1) during their stay for labor and 200 age-matched control women (group 2) were included in the study.

Objective: To assess the effects of gum chewing on postoperative bowel function after cesarean section.

Material And Methods: Women who underwent cesarean section were randomized to either a gum-chewing group (n = 74) or a non-gum-chewing group (n = 76). The two groups were compared with respect to the return of bowel activity, postoperative analgesic and antiemetic drug requirement and postoperative hospital stay.

Familial Mediterranean Fever (FMF) is an autosomal recessive disease which is characterized by recurrent, self-limiting, short attacks of serositis while abdominal pain is the most common symptom. The underlying clinical and pathological picture is that of acute peritonitis. These abdominal signs are often so striking that they mimic an acute abdominal calamity suggesting several possible gastrointestinal, gynecologic or urologic diagnoses.
