Introduction The aim of the study was to investigate whether melatonin has a protective effect against diminished ovarian reserve induced by smoking. Material and methods Seventy-two female Wistar-Albino rats were divided into 6 groups: group I (room air), group II (chronic cigarette smoking), group III (room air + 10 mg/kg subcutaneous melatonin), group IV (room air + 20 mg/kg subcutaneous melatonin), group V (chronic cigarette smoking + 10 mg/kg subcutaneous melatonin), group VI (chronic cigarette smoking + 20 mg/kg subcutaneous melatonin). For 45 days, rats were exposed to cigarette smoke through a smoking machine, then subcutaneous melatonin was administered. Apoptotic index, immunohistochemical scoring, ovarian follicle counting, ovarian tissue and serum malondialdehyde (MDA), superoxide dismutase (SOD), glutathione peroxidase (GPx), and catalase (CAT) analyses were carried out. Results All of the primordial, primary, secondary and mature follicle numbers were found to be significantly lowered in study groups. Increased HSCORE with anti-caspase-3 staining and a high follicular apoptotic index were demonstrated in the smoking group. Serum and ovarian tissue levels of MDA were found to be elevated with smoke exposure whereas lower MDA levels were determined in melatonin treated groups. Serum and tissue levels of SOD, GPx and CAT were shown to be reduced in the smoking group in comparison with melatonin treated and control groups. 20 mg/kg melatonin administration in the smoking group revealed significantly decreased HSCOREs and apoptotic indices. Conclusions Cigarette smoking has been definitely shown to be associated with impaired ovarian reserve with respect to significantly diminished numbers of primordial, primary, secondary and mature follicles. Dose-related treatment of melatonin in smokers may provide an evidently reduced apoptotic index and improved antioxidant activity in tissue.

Sirenomelia or “mermaid syndrome” is a rare congenital syndrome characterized by the anomalous development of the caudal region of the body. We present a case of sirenomelia diagnosed in the first trimester using two-dimensional and three-dimensional ultrasonographic examination. A nulliparous woman aged thirty years was referred to our perinatology unit for evaluation because of oligohydramnios at 12 weeks of gestation. Her medical history was unremarkable. There was no family history of genetic abnormalities. We identified a single lower extremity and severe oligohydramnios, which are characteristics of sirenomelia. Sirenomelia, a developmental defect involving the caudal region of the body, is associated with several internal visceral anomalies. Sirenomelia is fatal in most cases due to the characteristic pulmonary hypoplasia and renal agenesia. Prenatal diagnosis of sirenomelia may be difficult in the second or third trimester because of the severe oligohydramnios; it should be easier to diagnose sirenomelia in the first trimester. PRECIS: A diagnosis of sirenomelia may be easier to make during the first trimester because the amniotic fluid volume is relatively normal. During later periods, ultrasonographic diagnosis may be prevented because of severe oligohydramnios due to renal agenesis or dysgenesis.

Aim The aim of study is to compare maternal and fetal outcomes of pregnancies in which cerclage was placed following the loss of first fetus with those without cerclage placement in multiple pregnancies for delayed interval delivery. Methods Records of pregnancies in which the first fetus was lost between 13–26 weeks and delayed delivery experienced for retained fetus(es), were collected retrospectively. A total of 20 patients including 11 twins, seven triplets and two quadruplets were evaluated. Cases with cervical cerclage placed after the first delivery were evaluated as the cerclage group (n = 11) and the cases without cerclage placement were evaluated as the non-cerclage group (n = 9). Results Median duration of delay was 22 days (range, 3–121) for both groups; 40 days (range, 5–121) in cerclage group and 12 days (range, 3–46) in the non-cerclage group (P = 0.003). Average birthweight of retained fetus(es) in the cerclage group was 850 ± 153.6 g (mean ± standard error [SE]) and 549.5 ± 149.1 g (mean ± SE) in the non-cerclage group (P = 0.04). Delivery week of retained fetus(es), live birth rate, take-home baby rate and chorioamnionitis ratio were not different in between the groups. Conclusion Cervical cerclage after the first delivery is associated with a longer delivery interval and higher birthweight of retained fetus.

Aim: To determine whether serum prostate-specific antigen (PSA) levels are increased in polycystic ovary syndrome (PCOS) and the possibility of PSA to be used as a diagnostic marker of hyperandrogenism in females. Methods: A total of 43 women with PCOS and 43 age-matched healthy females were recruited in this prospective case-control study. The subjects were compared by means of demographic parameters, hormonal and metabolic measures and serum PSA levels. The correlations between this marker and a wide variety of hormonal, biochemical, anthropometric measures were evaluated. Student's t-test, χ2-test and Spearman's correlation analysis were used for the statistical analysis where appropriate. Statistical significance was assumed with a value of P

Purpose. To determine whether spectral Doppler measurements obtained from bilateral uterine, arcuate, radial, and spiral arteries in early gestation correlate with adverse pregnancy outcome. Methods. One hundred five pregnant women underwent transvaginal Doppler sonographic examination of uteroplacental circulation at 6–12 weeks' gestation. Resistance index (RI) and pulsatility index (PI) of bilateral uterine, arcuate, radial, and spiral arteries were measured. Diameters of gestational sac (GS) and yolk sac, crown–rump length (CRL), GS–CRL difference, and GS/CRL ratio were also recorded. Correlation was made with pregnancy outcome. Results. Sixteen women developed adverse pregnancy outcome. In these women, right uterine artery PI and RI were significantly higher than in women with normal obstetrical outcome. Spiral artery PI and RI values were also higher, but the difference was not statistically significant. GS–CRL difference, GS/CRL ratio, and yolk sac diameters were significantly lower in this group. Conclusion. Transvaginal Doppler examination can detect hemodynamic changes in uteroplacental circulation associated with subsequent adverse pregnancy outcome. © 2007 Wiley Periodicals, Inc.

Purpose. To study the blood flow patterns of utero-ovarian circulation in polycystic ovary syndrome (PCOS) and to assess their relationship with clinical, metabolic, and hormonal data. Methods. Forty-three women with PCOS and 43 age-matched healthy controls underwent Doppler examination of the utero-ovarian circulation in the follicular phase. Demographic, hormonal, and metabolic parameters were determined. Student's t-test, χ2-test, and Spearman correlation test were used for statistical analysis. Results. The ovarian artery pulsatility index (PI), resistance index (RI), and SD ratios were significantly lower in PCOS than in controls on the right side (p < 0.001, p = 0.02, p = 0.001, respectively) as well as on the left side (p < 0.001, p < 0.001, p < 0.001, respectively). The uterine artery systolic/diastolic (S/D) ratio was higher on both sides (p = 0.01) and the PI was higher on the left side (p = 0.02) in PCOS than in controls. The right uterine artery PI was positively correlated with luteinizing hormone and hemoglobin (r = 0.417, p = 0.043; r = 0.427, p = 0.033, respectively), the right uterine artery S/D was positively correlated with body mass index (r = 0.479, p = 0.015), and the left uterine artery PI was positively correlated with insulin (r = 0.458, p = 0.021). Conclusion. Doppler sonography of the utero-ovarian circulation may contribute to the evaluation of PCOS patients and a better understanding of the pathophysiology of this syndrome. © 2007 Wiley Periodicals, Inc.

Intrahepatic cholestasis of pregnancy (ICP) is a reversible pregnancy-specific cholestatic condition characterized by pruritus, elevated liver enzymes, and increased serum bile acids. It commences usually in the late second or third trimester, and quickly resolves after delivery. The incidence is higher in South American and Scandinavian countries (9.2%-15.6% and 1.5%, respectively) than in Europe (0.1%-0.2%). The etiology is multifactorial where genetic, endocrine, and environmental factors interact. Maternal outcome is usually benign, whereas fetal complications such as preterm labor, meconium staining, fetal distress, and sudden intrauterine fetal demise not infrequently lead to considerable perinatal morbidity and mortality. Ursodeoxycholic acid is shown to be the most efficient therapeutic agent with proven safety and efficacy. Management of ICP consists of careful monitoring of maternal hepatic function tests and serum bile acid levels in addition to the assessment of fetal well-being and timely delivery after completion of fetal pulmonary maturity. This review focuses on the current concepts about ICP based on recent literature data and presents an update regarding the diagnosis and management of this challenging issue.

Background: Primary sarcomas of the vulva are rare tumors that account for 1.8–3% of all vulvar malignancies. Malignant fibrous histiocytoma occurs infrequently on the vulva but nonetheless is the second most frequent sarcoma of this region. The purpose of this report is to review the diagnosis and therapy of this exceedingly rare tumor. Case: A 72-year-old woman was presented with a vulvar mass that was ultimately found to be a vulvar malignant fibrous histiocytoma. After surgical excision and 9 months of initial diagnosis, she returned with rapid localized progression and pulmonary metastases. Conclusion: Malignant fibrous histiocytoma arising in the vulva represents an example of vulvar sarcomas. Since the diagnostic criteria and natural history of this tumor still remain poorly defined, further case studies may be helpful to elucidate these issues as well as the optimal therapeutic approach of this heterogeneous group of malignancies.

Objective: The aim of the study was to determine the risk factors, prevalance, epidemiological parameters and maternal-perinatal outcome in pregnant women with hypertensive disorder. Materials and methods: A retrospective analysis was undertaken on 255 consecutive cases of hypertensive disorder in pregnancy who were managed at Kocaeli University, School of Medicine, Department of Obstetrics and Gynecology from June 1997 to November 2004. Demographic data involving age, parity, gestational week, clinical and laboratory findings were recorded from the medical files. Additionally delivery route, indications of cesarean section, fetal and maternal complications were determined. Statistical analysis was performed by SPSS programme using Kruskal Wallis nonparametric test, ANOVA (Analysis of variance) and chi-square tests. Results: Of 5,155 deliveries in our clinic during the defined period, 438 cases (8.49%) were managed as hypertensive disorder of pregnancy. Medical records of 255 cases could be avaliable. Of 255 cases, 138 patients (54.11%) were found to have severe preeclampsia while 88 cases (34.50%) were diagnosed as mild preeclampsia. Twenty-nine patients (11.37%) were suffering from chronic hypertension. Of 138 severely preeclamptic cases, 28 cases (11%) had eclamptic convulsion and another 28 patients (11%) were demonstrated to have HELLP syndrome. Intrauterine growth restriction, oligohydramnios, placental ablation were the obstetric complications in 75 (29.4%), 49 (19.2%), 19 (7.5%) cases, respectively. Additionally multiple pregnancy and gestational diabetes mellitus were noted in 5.9% (n:15) and 3.9% (n:10) of the patients. Delivery route was vaginal in 105 patients (41.2%) while 150 patients (58.8%) underwent cesarean section with the most frequent indication to be fetal distress in 69 cases (46%). Cesarean section rate seemed to be the lowest (48.3%) in chronic hypertensive women while the highest (63.8%) in severe preeclamptic patients. Maternal mortality occured in 3 cases (1.2%) and all of those cases were complicated with HELLP syndrome. Intracranial bleeding was the cause of maternal death in one case while the other two cases were lost due to acute renal failure and disseminated intravascular coagulation, respectively. Intrauterine fetal demise was recorded in 24 cases on admission. Ten fetuses died during the intrapartum period. Mean gestational age and birth weight were 28±3.5 and 1000±416 g, respectively in this group. In these ten women, five cases were diagnosed as HELLP syndrome, two were severely preeclamptic and three were eclamptic. Perinatal mortality rate was found to be 144/1,000 births Conclusion: Hypertensive disorder of pregnancy is associated with increased risk of maternal-perinatal adverse outcome. The complications of severe preeclampsia and eclampsia could be prevented by more widespread use of prenatal care, education of primary medical care personnel, prompt diagnosis of high-risk patients and timely referral to tertiary medical centers.

Distal vaginal agenesis is one of the rarest congenital malformations of female genital tract. We describe successfully operated teenaged monozygotic twins by combined abdominal and perineal approach. The imaging studies and surgical experience were presented.

Summary Acute fatty liver of pregnancy (AFLP) is a rare disorder of unknown aetiology that is diagnosed typically in the third trimester or early postpartum period. The incidence is estimated to be 1/6692–1/13,328. The obstetric team must have a high index of suspicion of this pathology, particularly in the presence of clinical and laboratory findings, such as nausea, vomiting, jaundice, increased serum transaminase levels, increased prothrombin time and hypoglycaemia. Early diagnosis followed by prompt delivery and supportive care provides significantly improved maternal and perinatal outcome. Delay in diagnosis of this obstetric emergency may lead to rapid progression to hepatic failure, disseminated intravascular coagulation (DIC), haemorrhage, encephalopathy, multiple organ failure and finally death. The case of a 34-year-old woman, gravida 3, para 2, with AFLP complicated with DIC is presented herein with a review of literature and discussion of its origin.

To evaluate the maternal and fetal outcome in 44 pregnancies complicated with HELLP syndrome and to investigate the role of platelet counts in its prognosis. A retrospective analysis of the medical records of 44 patients with the diagnosis of hemolysis elevated liver enzymes and low platelet count between June 1997 and January 2009 was performed. The patients were divided into two groups according to blood platelet count: platelet count

Objective To determine whether 25OH-D levels in the follicular fluid (FF) of infertile women undergoing IVF demonstrate a relationship with IVF cycle parameters and outcome, hypothesizing that levels of 25OH-D in body fluids are reflective of vitamin repletion status. Design Prospective cohort study. Setting Academic tertiary care center. Patient(s) Eighty-four infertile women undergoing IVF. Intervention(s) Follicular fluid from follicles ≥14mm; serum (n = 10) and FF levels of 25OH-D. Main Outcome Measure(s) Clinical pregnancy (CP), defined as evidence of intrauterine gestation sac on ultrasound, following IVF; IVF cycle parameters. Result(s) Serum and FF levels of 25OH-D were highly correlated (r = 0.94). In a predominantly Caucasian population (66%), significantly lower FF 25OH-D levels were noted in Black versus non-Black patients. Significant inverse correlations were seen between FF 25OH-D levels and body mass index (r = –0.25). Significantly higher CP and implantation rates were observed across tertiles of FF25OH-D; patients achieving CP following IVF (n = 26) exhibited significantly higher FF levels of 25OH-D. Multivariable logistic regression analysis confirmed FF 25OH-D levels as an independent predictor to success of an IVF cycle; adjusting for age, body mass index, ethnicity, and number of embryos transferred, each ng/mL increase in FF 25OH-D increased the likelihood for achieving CP by 6%. Conclusion(s) Our findings that women with higher vitamin D level in their serum and FF are significantly more likely to achieve CP following IVF–embryo transfer are novel. A potential for benefit of vitamin D supplementation on treatment success in infertile patients undergoing IVF is suggested and merits further investigation.

Endometriosis, defined as the presence of endometrial tissue outside the uterus, is a challenging condition associated with substantial morbidity. Management of endometriosis must be individualized according to the desired treatment outcome, whether it is relief of pain, improvement of fertility, or the prevention of recurrence. For alleviation of endometriosis-associated pain, medical treatment is generally successful, with no medical agent being more efficacious than another in spite of significantly differing side-effect profiles. Surgical therapy has also been demonstrated to reduce pain scores in comparison with expectant management, although conservative surgery has been frequently associated with recurrence. The efficacy of combination therapies still remains to be clarified. For treatment of endometriosis-associated infertility, suppressive medical treatment has been proven to be detrimental to fertility and should be discouraged, while surgery is probably efficacious for all stages. Controlled ovarian hyperstimulation with intrauterine insemination is recommended in early-stage and surgically corrected endometriosis. Combined surgery with GnRH analog treatment has been proposed to be first-line therapy, followed by IVF as second-line therapy in advanced cases. More rigorously designed randomized clinical trials focusing on the endocrinological, immunological, and genetic aspects of endometriosis are necessary to refine conclusions regarding the etiopathogenesis and therapeutic innovations of this perplexing disease.

Aim: To determine how fetal pulse oximetry behaves in various cardiotocographic (CTG) tracings and correlates with neonatal outcome. Patients and Methods: Pregnant women undergoing active labor with singleton pregnancies of 32–42 weeks were enrolled. CTG recordings were reassuring or nonreassuring (namely variable or persisting late decelerations). Pulse oximetry values during labor and changing throughout deceleration and recovery phases, duration and frequency of pulse oximetry recordings

Albeit very uncommon, the hernia sac may contain unusual structures such as vermiform appendix, acute appendicitis, ovary, fallopian tube and, urinary bladder. Most of the cases of hernia containing ovary and fallopian tubes were reported to be found in children and, often accompanied with other congenital anomalies of genital tract. We present the first case of sliding inguinal hernia containing right ovary and fallopian tube and a right paraovarian cyst in 80-year-old, multiparous patient without any associated genital anomaly. The hernia was repaired with plication darn, while the paraovarian cyst was excised and adnexa were preserved. It is of utmost importance to keep in mind that the hernia sac may contain almost any abdominal organ, and surgical dissection should be carried out accordingly. Pathophysiologically, the ovary might be simply pulled along with a sliding paraovarian cyst or the paraovarian cyst might be accompanying the maldescended ovary. There seems to be a need for clinical and experimental studies to further explain the mechanisms that apply to the pathogenesis of sliding inguinal hernias.

To compare efficacy and safety of vaginal misoprostol (PGE(1) analog) with dinoprostone (PGE(2) analog) vaginal insert for labor induction in term pregnancies.A total of 112 women with singleton pregnancies ofor =37 weeks of gestation, and low Bishop scores underwent labor induction. The subjects were randomized to receive either 50 mug misoprostol intravaginally every 4 h to a maximum of five doses or a 10 mg dinoprostone vaginal insert for a maximum of 12 h. Time interval from induction to vaginal delivery, vaginal delivery rates within 12 and 24 h, requirement of oxytocin augmentation, incidence of tachysystole and uterine hyperstimulation, mode of delivery, rate of cesarean section due to fetal distress and neonatal outcome were outcome measures. Student's t test, Chi square test, Fischer's exact test were used for statistical analysis.Time interval from induction to vaginal delivery was found to be significantly shorter in misoprostol group when compared to dinoprostone subjects (680 +/- 329 min vs. 1070 +/- 435 min, P0.001). Vaginal delivery rates within 12 h were found to be significantly higher with misoprostol induction [n = 37 (66%) vs. n = 25 (44.6%); P = 0.02], whereas vaginal delivery rates in 24 h did not differ significantly between groups [n = 41 (73.2%) vs. n = 36 (64.2%); P = 0.3]. More subjects required oxytocin augmentation in dinoprostone group [n = 35 (62.5%) vs. n = 20 (35.7%), P = 0.005] and cardiotocography tracings revealed early decelerations occurring more frequently with misoprostol induction (10.7 vs. 0%, P = 0.03). Tachysystole and uterine hyperstimulation, mode of delivery, rate of cesarean sections due to fetal distress and adverse neonatal outcome were not demonstrated to be significantly different between groups (P = 1, P = 0.5, P = 0.4, P = 0.22, P = 0.5).Using vaginal misoprostol is an effective way of labor induction in term pregnant women with unfavorable cervices, since it is associated with a shorter duration of labor induction and higher rates of vaginal delivery within 12 h. Misoprostol and dinoprostone are equally safe, since misoprostol did not result in a rise in maternal and neonatal morbidity, namely, tachysystole, uterine hyperstimulation, cesarean section rates and admission to neonatal intensive care units as reported previously in literature.

To investigate placental expression of insulin-like growth factor-I (IGF-I), fibroblast growth factor-basic (FGF-b) and neural cell adhesion molecule (N-CAM) regarding the pathogenesis of pregnancies with small for gestational age (SGA) fetuses. An immunohistochemical analysis using anti-IGF-I, anti-FGF-b and anti-N-CAM antibodies was carried out on 4% paraformaldehyde-fixed placental tissues of third trimester pregnancies complicated with SGA fetuses (n=12) and subjects exhibiting appropriately grown fetuses (n=10). Immunostaining patterns of chorionic villi and amniochorionic membranes were assessed. IGF-I, FGF-b and N-CAM immunostainings in chorionic villi demonstrated significantly increased immunoreactivities in cytotrophoblasts of SGA cases, whereas increased IGF-I immunostaining in syncitiotrophoblasts and increased N-CAM immunostaining in capillary endothelium were noted in the same group. IGF-I, FGF-b and N-CAM immunostainings in amniochorionic membranes revealed significantly decreased IGF-I immunoreactivities in extravillous trophoblasts and increased IGF-I immunoreactivities in decidual cells of SGA cases, while significantly decreased N-CAM immunoreactivities in both decidual cells and extravillous trophoblasts were noted. FGF-b immunostaining revealed no significant differences in both extravillous trophoblasts and decidual cells of SGA cases. Increased placental expression of IGF-I, FGF-b and N-CAM may act in an autocrine and/or paracrine manner to restore the impaired trophoblastic proliferation, migration and metabolism at all gestational stages by means of a positive feedback mechanism.

Implantation of conception material within a cesarean section scar is an extremely rare form of ectopic pregnancy with devastating complications such as uterine rupture and intractable bleeding. Both 2-D and 3-D transvaginal ultrasonographic devices are used adequately for precise diagnosis but there is still a lack of consensus concerning management strategies. No therapeutic modality is suggested to be entirely efficacious and safe for preserving uterine integrity. We present here a 29-year-old woman with vaginal bleeding and a gestational sac with a viable embryo of 6 weeks of age that was implanted in a cesarean section scar. Serum beta-hCG levels were 16 792 mIU/mL. Following an unsuccessful treatment course of systemic methotrexate the patient underwent operative hysteroscopy. Minimally invasive hysteroscopic resection of the ectopic gestational mass without major complication appears to be an alternative therapeutic approach with minimal morbidity and preservation of future fertility.

Gastric carcinoma associated with pregnancy appears to be an extremely rare entity. It is usually diagnosed at advanced stages of the disease and presents a grave prognosis. Since the fatal outcome shows a rapid course within months of diagnosis, prompt gastroduodenal endoscopic examination following early clinical suspicion is mandatory. A case of 29 year–old pregnant woman with 31 weeks of gestation is herein presented. The women was diagnosed as gastric adenocarcinoma while being investigated for intractable nausea, vomiting, and a concomitant epigastric mass. She underwent radical gastric resection and received six cycles of adjuvant chemotherapy following vaginal delivery of a healthy 1950 g fetus. The patient was dead 20 weeks after the surgery due to pulmonary and hepatic metastasis.

Magnetic resonance (MR) imaging and MR angiography were used for the differential diagnosis and preoperative planning of a 17 weeks of age rudimentary horn pregnancy. A 26-year-old primigravida was referred to our hospital with a preliminary diagnosis of abdominal pregnancy. After an inconclusive ultrasound evaluation we were able to identify a rudimentary horn pregnancy, extent of the placental invasion, and the vascular supply via MR imaging and time of flight sequence MR angiography. The obtained data were also used for preoperative planning, which resulted in an uncomplicated, prerupture laparotomy for pregnancy termination and a healthy female.

Objective: To determine serum leptin levels in hypertensive disorder of pregnancy. Materials and methods: In this prospective, cross-sectional, case control study, we measured serum leptin levels of 58 hypertensive pregnant women and 54 normal pregnant women. We also did blood and urine analysis for the evaluation of the severity of hypertensive disorder of pregnancy. The patients were followed until after delivery and information about labour was recorded. We analysed the difference and correlation between anthropometric measures, hormonal and biochemical parameters, and serum leptin levels in two groups. Results: In the study group, serum leptin levels were determined to be higher than the control group. Neonatal birth weight was significantly lower in the hypertensive group. While the serum uric acid, urea, aspartate aminotransferase, fibronectin, and fasting blood glucose levels were found to be higher, serum total protein and albumin levels were significantly lower among the hypertensive pregnant women. Hypertensive pregnant women were more insulin resistant. Serum leptin levels were highly and positively correlated with serum fibronectin, and C peptide levels. A negative significant correlation was observed between maternal serum leptin levels and neonatal birth weight among the pregnant women having the hypertensive disorders. Conclusion: Serum leptin levels in hypertensive pregnant women appear to be higher. The determination of serum leptin levels may be as important as serum fibronectin and C peptide levels in the management of hypertensive disorder of pregnancy. C peptide and insulin may be due to hyperinsulinemia which leads to increased stimulation of leptin production by fatty tissue. Insulin resistance which appears in late pregnancy is more significant especially in pregnancies complicated by preeclampsia.

Primary ovarian choriocarcinoma arising presumably from a germ cell is extremely rare. Besides arising gestationally or nongestationally, it may be pure or mixed with other germ cell tumors like immature teratoma, dysgerminoma, polyembryoma.We present a case of a 22-year-old woman diagnosed with pure nongestational choriocarcinoma of the ovary with a review of the literature and discussion of its origin.
