RESUMEN
OBJECTIVE: Analysis of the annual distribution of cesarean sections and indications between 2010 and 2015 in our clinic. MATERIAL AND METHODS: Medical records of 10,437 cesarean section patients from a total number of 24,283 deliveries performed at Department of Obstetrics and Gynecology between 2010-2015 were evaluated retrospectively. The indications for Cesarean section were analyzed and compared based on years. RESULTS: The lowest cesarean section rate was 18.67% in 2011 and the highest rate was 24.5% in 2013, and the annual rates were close to each other in this 6-year period (p > 0.05). History of uterine surgery was the indication with the highest rate of 49.52%, while fetal distress was the second most frequent with 12.53%; presentation anomalies were observed as the most frequent third indication with 7.55%, and umbilical cord prolapse was the least frequent indication with 0.33%. CONCLUSIONS: Patient education about normal delivery and providing means for pain control during normal delivery, improvement in physical conditions of the clinics, frequent and regular training of the assisting staff with obstetrics physicians are important to diminish the rates of primary cesarean sections. In addition, a normal delivery after a previous cesarean section must be encouraged.

OBJECTIVE: To determine the impact of recombinant luteinizing hormone (rLH) combined with vaginal progesterone (P)for luteal supplementation on in vitro fertilization (IVF) pregnancy outcomes in high-responder patients undergoing long gonadotropin-releasing hormone (GnRH) agonist cycles. STUDY DESIGN: A total of 47 patients undergoing IVF cycles with the serum estradiol levels of > or = 2,500 pg/mL on the day of human chorionic gonadotropin administration were included in this prospective randomized study. Patients were divided into 2 treatment groups: the control group (n = 23) used luteal vaginal P, and the study group (n = 24) received a combination of vaginal P and 75 IU rLH, 4 doses every 3 days, starting on the day of embryo transfer. The main outcome measure was the clinical pregnancy rate (PR). RESULTS: The study group had 11 pregnancies (45.8%), while the control group had 6 (26.1%). There was no significant difference between the groups in clinical PRs (p = 0.15). No differences were found with respect to the implantation rate, miscarriage rate, and multiple PR. CONCLUSION: Our data show that luteal supplementation with rLH combined to vaginal P was not found to improve pregnancy outcomes in high responder patients undergoing long GnRH agonist IVF treatments.

PURPOSE: To evaluate the influence of ultrasound guidance during intrauterine insemination (IUI) on pregnancy rates (PRs). The impacts of two different groups of providers were also investigated. METHODS: Study population consisted of 387 gonadotropin stimulated IUI cycles performed for unexplained infertility. The patients were randomized into two groups as ultrasound-guided IUI (n = 180) and classical IUI (n = 207). Pregnancy rates were compared. Two groups were further analyzed based on the experience of the provider (senior versus junior subgroups) who performed IUI. RESULTS: Pregnancy rates were higher in the ultrasound-guided IUI group (17.2%) compared to the classical IUI (10.1 %) (p = 0.042). In further analysis based on the experience of the provider; in the classical IUI group, PRs were similar for both subgroups, however, in the ultrasound-guided group it was higher when IUI was performed by a senior physician (21.7 versus 9.2%, p = 0.033). Logistic regression revealed that the experience of the provider was the independent variable for improved PRs. CONCLUSIONS: Ultrasound guidance improves PRs only when a senior provider performs the IUI procedure. It seems that the experience of the provider physician is one of the determinants of IUI success.

Placental type 3 iodothyronine deiodinase (D3) potentially protects the fetus from the elevated maternal thyroid hormones. Na(+)/I(-) symporter (NIS) is a plasma membrane glycoprotein, which mediates active iodide uptake. Our objectives were to establish the distribution of NIS and D3 gene expressions in the placenta and the amniotic membrane and to investigate the relationship between placental D3 and NIS gene expressions and maternal iodine, selenium, and thyroid hormone status. Thyroid hormones, urinary iodine concentration (UIC), and selenium levels were measured in 49 healthy term pregnant women. NIS and D3 gene expressions were studied with the total mRNA RT-PCR method in tissues from maternal placenta (n = 49), fetal placenta (n = 9), and amniotic membrane (n = 9). NIS and D3 gene expressions were shown in the fetal and maternal sides of the placenta and amniotic membrane. Mean blood selenium level was 66 ± 26.5 µg/l, and median UIC was 143 µg/l. We could not demonstrate any statistically significant relationship of spot UIC and blood selenium with NIS and D3 expression (p > 0.05). Positive correlations were found between NIS and thyroxine-binding globulin (TBG) (r = 0.3, p = 0.042) and between D3 and preoperative glucose levels (r = 0.4, p = 0.006). D3 and NIS genes are expressed in term placenta and amniotic membrane; thus, in addition to placenta, amniotic membrane contributes to regulation of maternofetal iodine and thyroid hormone transmission. Further studies are needed to clarify the relationship between maternal glucose levels and placental D3 expression and between TBG and placental NIS expression.

PURPOSE: Ghrelin, an endogenous ligand for the growth hormone secratogogue receptor, and its receptors are found in the reproductive organs and placenta. Motilin is produced from the endocrine cells of the duodeno jejunal mucosa and considered to be a regulator of interdigestive migrating contractions. Aim of this study is to investigate ghrelin and motilin levels in patients with hyperemesis gravidarum. METHODS: A total of 56 patients with singleton pregnancies in the first trimester were recruited in the study, 39 with hyperemezis gravidarum and 17 normal pregnant women. Patients with medical complications and body mass index <18 or >25 were excluded. Fasting plasma ghrelin and motilin concentrations were measured. Fasting blood glucose, liver enzymes, blood urea nitrogen, creatinin, estradiol, progesterone, human chorionic gonadotropin, and thyroid function tests were also investigated. RESULTS: Ghrelin levels were significantly higher in patients with hyperemesis group than the normal pregnant women (p = 0.025). Serum estradiol levels were also higher in the hyperemesis group (p = 0.001). No significant difference was observed in plasma motilin levels between the two groups. In correlation analyses, maternal ghrelin was positively correlated with estradiol (r = 0.29, p = 0.029) in the whole cohort. CONCLUSION: There are a few studies about the course of circulating ghrelin levels during human pregnancy. Ghrelin administration increases food intake through central mechanisms but its effects on appetite in relation to human pregnancy is unknown. The increased levels of ghrelin in hyperemesis gravidarum might be a compensatory mechanism to restore the energy metabolism of the pregnant women.

OBJECTIVE: To investigate effect of the afterloaded external guidance embryo transfer technique on pregnancy rates in single embryo transfer intracytoplasmic sperm injection (ICSI) cycles. MATERIAL AND METHODS: This retrospective study was performed at the Dr. Zekai Tahir Burak Women's Health Research and Education Hospital. Three hundred and thirteen women who underwent ICSI were included in the study. Subjects were categorized according to the embryo transfer technique; Group 1 (n: 232): easy transfer with a soft catheter, Group 2 (n: 45): after external guidance transfer, and Group 3 (n: 36): difficult transfer with a stylet. Basal parameters, clinical and laboratory IVF outcomes and pregnancy rates were studied. RESULTS: Infertility etiology, basal follicle stimulating hormone (FSH) levels, antral follicle count, duration of stimulation, total dose of gonadotropin, peak estradiol levels, endometrial thickness, oocyte number, 2 PN, and fertilization rate were similar between the three groups (p>0.05). Despite the decreased pregnancy rate in Group 3, there were no differences in clinical pregnancy rates among the groups (p=0.204). CONCLUSION: Embryo transfer is one of the critical steps in assisted reproduction procedures. Using the afterloaded external guidance embryo transfer technique did not improve pregnancy rates.
RESUMEN
PURPOSE: To study the relation of pelvic pain symptoms and pelvic adhesions to Doppler ultrasound findings in patients with ovarian endometriomas. METHODS: 62 patients who underwent laparoscopic surgery for endometrioma were divided into two groups according to their pelvic pain symptoms. Group 1 (n = 27) included patients with pelvic pain, group 2 (n = 35) asymptomatic patients. Patients were evaluated for the vascularization of endometrioma by transvaginal color and power Doppler ultrasonography before the surgery. The presence and amount of blood flow reported in terms of a color scale, pulsed Doppler indices, and dense pelvic adhesions were compared between the groups. The relation of Doppler ultrasound findings to the dense pelvic adhesions was also analyzed. RESULTS: Blood flow was present in 74.1 % (n = 20) of patients in group 1 and 68.6 % (n = 24) in group 2 (p = 0.63). The volume and vascularization of the endometriomas, pulsed Doppler indices, stage of endometriosis, and the presence of dense pelvic adhesions were also similar. Patients with dense pelvic adhesions had significantly higher amount of blood flow compared to patients without adhesions (p = 0.006), but the mean pulsatility index and resistance index were not different between the groups (p = 0.55 and 0.59, respectively). CONCLUSIONS: Pelvic pain symptoms were not found to be related to endometrioma vascularization. On the other hand, we observed an association between higher vascularized endometrioma and the presence of dense pelvic adhesions.

OBJECTIVES: To assess hysteroscopic findings in patients with two, three, and four or more, consecutive miscarriages, and to compare the prevalence of uterine abnormalities between women with different numbers of such miscarriages. METHODS: Two hundred and sixty-five women with two or more consecutive miscarriages were enrolled in the study. Patients were divided into three groups according to the number of their miscarriages: Group 1 (two miscarriages, n = 151), Group 2 (three miscariages, n = 69), and Group 3 (four or more miscarriages, n = 45). All participants underwent a diagnostic hysteroscopy. Congenital (arcuate uterus, septate uterus, unicornuate uterus) and acquired uterine abnormalities (intrauterine adhesions, polyp and submucous myoma) were recorded. The hysteroscopic results were compared between the groups. RESULTS: No anomalies were detected in 152 patients (57%), whereas 43 (16%) had a septate uterus, 30 (11%) an arcuate uterus, three (1%) a unicornuate uterus, 18 (7%) intrauterine adhesions, 17 (6 %) endometrial polyps, and two (1%) a submucous myoma. No significant differences were found between the groups with regard to either congenital or acquired uterine abnormalities. CONCLUSIONS: Patients with two, three, and four or more consecutive miscarriages have a similar prevalence of uterine anatomical abnormalities. Diagnostic hysteroscopy should be carried out after two such miscarriages.

AIM: The aim of the present study was to evaluate the role of oxidative stress and DNA damage in preeclampsia and intrauterine growth restriction (IUGR). MATERIAL AND METHODS: Twenty-four patients with preeclampsia, 20 patients with IUGR fetus and 37 healthy pregnant women were enrolled in the study. The total oxidant status (TOS) and antioxidant status (TAS) of plasma were measured using a novel automated colorimetric measurement method. Sister chromatid exchange (SCE) and micronuclei analysis were performed on peripheral blood lymphocytes of cases and controls. RESULTS: Women whose pregnancies were complicated with preeclampsia and IUGR had elevated levels of TOS and TAS when compared with healthy pregnant women (median TOS values: 9.73, 10.6 and 8.06, P = 0.001; median TAS values: 1. 77, 1.54 and 1.44, P < 0.001, respectively). The frequencies of SCE were only found to be increased in women with IUGR fetus compared with healthy pregnant women (8.81 vs 7.5, respectively, P = 0.02). Multivariable linear regression analysis for both TOS and TAS showed a significant relation between these variables and uric acid. CONCLUSION: Increased oxidative stress and antioxidative defense mechanisms may contribute to disease processes both in preeclampsia and IUGR.

Introduction. Asymptomatic bacteriuria (ASB), occurring in 2-11% of pregnancies, is a major predisposition to the development of pyelonephritis, which is associated with obstetrical complications, such as preterm labor and low birth weight infants. The aim of this study was to determine the prevalence of ASB, the antibacterial susceptibilities of the isolated microorganisms and the associated risk factors in an outpatient clinical setting in Zekai Tahir Burak Women's Health Education and Research Hospital in Ankara, Turkey. Material and Methods. Between December 2009 and May 2010, pregnant women admitted to the antenatal outpatient clinic were included in this study. The results of a complete urine analysis, midstream urine culture and antibacterial susceptibility were evaluated. Results. Of the 2011 pregnant women included, 171 had ASB (8.5%). E. coli was the most frequently isolated microorganism (76.6%), followed by Klebsiella pneumonia (14.6%). Both microorganisms were highly sensitive to fosfomycin, sensivity being 99.2% for E. coli and 88% for Klebsiella pneumonia. Conclusions. In this certain geographical region, we found E. coli as the most common causative agent of ASB in the obstetric population and it is very sensitive to fosfomycin. We recommend fosfomycin for ASB in pregnant women due to its high sensitivity, ease of administration and safety for use in pregnancy.
