OBJECTIVE: The aim of our study was to present our case series of the trial of labor after a caesarean (TOLAC) and determine significant predictors for a successful vaginal birth after a caesarean (VBAC) PATIENTS AND METHODS: Women with previous single caesarean deliveries who underwent TOLAC between January 2016-December 2019 were included in the study (n = 474). All files were analyzed in terms of demographic characteristics, obstetric history, history of index pregnancy and medical characteristics of previous caesarean delivery. For each current pregnancy, we recorded time from the previous delivery, the BISHOP and TOLAC scores at admission, induction of labor, gestational age at delivery, estimated fetal weight, intrapartum characteristics, mode of delivery and intra-operative findings. RESULTS: Among 474 women who had a previous caesarean delivery and gave consent for TOLAC, 216 resulted in a successful vaginal delivery, whereas 258 underwent repeat caesarean delivery. One hundred and seventy-nine women gave up trial of vaginal delivery during labor. The success rate of VBAC after exclusion of caesarean cases due to maternal requests was 73.2%. The induction rate was significantly higher in cases with successful VBAC (40% vs. 29.1%). The risk of uterine rupture was 0.42% in cases with labor induction. ROC analysis showed significant predictive values of the TOLAC score, body mass index (BMI), the number of previous VBACs and the number of previous vaginal deliveries, birth weight and the BISHOP score at admission. CONCLUSIONS: Our data showed us that major determinants for successful VBAC following labor are the BISHOP score at admission, number of previous vaginal deliveries, body mass index, birth weight and the TOLAC score calculated at admission.

Background: Postpartum hemorrhage has been one of the most common cause of maternal morbidity and mortality. An association between pre-eclampsia (PE) and postpartum hemorrhage has been shown in previous studies. The aim of this study was to compare some characteristics of postpartum hemorrhage between women with and without PE. Methods: Some characteristics of postpartum hemorrhage were compared between women with ( n  = 34) and without PE ( n  = 34). Majority of the cases underwent low molecular heparin administration at postpartum eighth hour, however, in cases who did not give satisfactory responses to blood product transfusions, to block suspected disseminated intravascular coagulation (DIC) secondary to the PE induced vascular injury, low molecular weight heparins were started within 2 h of postpartum hemorrhage. Some characteristics of cases with and without PE and with and without early low molecular weight heparin administration were compared. Results: There were five cases who needed massive transfusions in group with PE, conversely, no case required massive transfusion in group without PE ( p  < .05), in these five cases prophylactic dose low molecular weight heparin was started within 2 h of postpartum period, these cases determined according to the changes in hematocrit, platelet, and fibrinogen levels with corresponding transfusions. Mean systolic and diastolic blood pressures were significantly higher in PE group. Highest lactate dehydrogenase (LDH) level during follow up was significantly higher in group with PE. Mean numbers of erythrocyte, thrombocyte, and fibrinogen transfusions were significantly higher in PE group. Duration of hospital stay was also significantly higher in group with PE. Conclusions: Postpartum hemorrhage in women with PE may be resistant to blood product transfusions due to DIC and vicious cycle can be blocked by early low molecular weight heparin administration.

Polycystic ovary syndrome (PCOS) is a metabolic disorder associated with obesity and energy metabolic system disturbances in adipose tissue. Neuregulin 4 (NRG4), which is secreted by adipose tissue, regulates energy metabolism. In the present study, we aimed to evaluate the association between serum NRG4 levels in obese and normal weight PCOS patients. This cross-sectional study was conducted at a tertiary hospital in Turkey from April to August 2017. We included 148 women who were divided into four groups as follows: 40 normal weight and 39 obese PCOS women diagnosed according to the Rotterdam criteria as well as 38 normal weight and 31 obese, age-matched, non-hyperandrogenemic women with a regular menstrual cycle (controls). Levels of serum NRG4, anti-Müllerian hormone (AMH), fasting blood glucose (FBG), insulin, and high-sensitivity C-reactive protein (hs-CRP); lipid and hormone profiles; insulin resistance indices [homeostasis model assessment of insulin resistance (HOMA-IR)];and anthropometric parameters were evaluated. Serum NRG4 levels were elevated in the normal weight PCOS group than in the control group. Moreover, serum NRG4 levels were higher in the obese PCOS group than in the normal weight PCOS and obese control groups ( p  < .01). Serum NRG4 levels were positively correlated with body mass index (BMI); waist/hip ratio; HOMA-IR; and levels of triglycerides, hs-CRP, FBG, insulin, AMH, and dehydroepiandrosterone sulphate. Multiple regression analyses revealed that serum NRG4 levels were independently associated with BMI. Obesity appears to be the most influential factor for NRG4 secretion in PCOS patients. Management of obesity may be a key factor for resolving PCOS-related metabolic abnormalities and fertility problems. Impact Sstatement What is already known on this subject? PCOS is a dynamic syndrome with different clinical and metabolic features during the reproductive age. PCOS is associated with various metabolic abnormalities, such as insulin resistance (IR), glucose intolerance, dyslipidemia, and obesity (particularly visceral obesity) as well as long-term complications, such as type 2 diabetes and cardiovascular diseases. Neuregulin 4 (NRG4), which is secreted by adipose tissue, regulates energy metabolism. What do the results of this study add? To the best of our knowledge, this was the first study investigating NRG4 levels in PCOS patients with different BMIs. Obesity appears to be the most influential factor for NRG4 secretion in these patients. Managing obesity may be a key factor for resolving PCOS-related metabolic abnormalities. What are the implications of these findings for clinical practice and/or further research? Further research in PCOS is warranted to ameliorate obesity, and our study can provide basis for future studies investigating NRG4 levels in PCOS patients with different phenotypes as well as studies of gene polymorphisms, AMH, and infertility and can contribute to the elucidation of problems related to the pathophysiology of PCOS.

Aim: Prostaglandins have a dual action of cervical ripening and induction of uterine contraction. This study was designed to compare the effectiveness of vaginal washing just before insertion of intravaginal dinoprostone., Methods: A randomized controlled trial was conducted at the Zeynep Kamil Women and Children's Health Training and Research Hospital. One hundred and ninety-one women with singleton, term pregnancy who underwent labor induction were randomly assigned to two groups: Group 1 consisted of 95 pregnant women with vaginal washing before intravaginal dinoprostone (Propess system for slow release system of 10 mg of dinoprostone) insertion (study group), and 96 pregnant women constituted the control group who did not undergo vaginal washing before intravaginal dinoprostone insertion. A parallel randomized controlled trial was conducted with an allocation ratio of 1:1 to compare the effectiveness of vaginal washing before intravaginal dinoprostone insertion., Results: The groups had similar mean age, body mass index, gestational age, gravidity, parity and Bishop score before agent insertion (P > 0.05). Duration of dinoprostone kept intravaginally, duration from the beginning of dinoprostone insert vaginally to the active phase of labor and duration from the time of intravaginal dinoprostone insertion to delivery were significantly longer in the control group (P < 0.05). Uterine hyperstimulation rate was significantly higher in study group compared to control group (P < 0.05). Meconium passage, fetal infection and neonatal intensive care unit admission were significantly higher in the control group (P < 0.05)., Conclusion: Vaginal washing before intravaginal dinoprostone insertion may increase Prostaglandin E2 bioavailability as we found shorter duration and better outcome of labor induction in the present study., (© 2018 Japan Society of Obstetrics and Gynecology.)

Objectives: The aim of this study was to compare some clinical characteristics of two different management alternatives in pregnants with placental invasion anomalies., Methods: We conducted a single-center retrospective study of all patients who delivered with invasive placentation between January 2016 and May 2017. We included only the patients with placental invasion anomaly and planned cesarean section., Results: Fifty-one pregnants met the inclusion criteria. Cesarean hysterectomy was performed in 29 patients and segmental resection in 22. Major intraoperative and postoperative complications were comparable between the two groups. There were significant differences between the groups with regard to gravidity, pre- and post-operative hemoglobin concentrations, number of packed red blood cell transfused, and operation time (p < .05)., Conclusions: An initial fertility conserving surgical procedure is an option in patients with extensive invasive placentation with lesser transfusion requirement and shorter operative time compared to cesarean hysterectomy.

The study aimed to assess the effect of high estrogen exposure and coasting on cycle outcome in women at risk for developing ovarian hyperstimulation syndrome (OHSS). Retrospective case-control study was conducted to figure out the outcomes of GnRH antagonist cycles in which women were at risk to develop OHSS. Women who underwent coasting (n = 100) were compared with a control group of women who did not undergo coasting (n = 287). Effect of endometrial estrogen exposure was determined by calculating area under curve of temporal estrogen measurements (AUCEM) through the cycle. Among 387 women with PCOS, 100 cases were required to undergo coasting to avoid OHSS. All participants reached to embryo transfer stage and clinical pregnancy rate was 44% in group with coasting whereas 39% in group without coasting (p > .05). AUCEM was a significant predictor for the cases who required coasting to avoid OHSS (AUC = 0.754, p < .001). Optimal cut off value was calculated to be 6762 with 71% sensitivity and 67% specificity. ROC analysis showed no predictive value of AUCEM for clinical pregnancy in subgroup of women with coasting (AUC = 0.496, p > .05). Consistently, ROC analysis showed no predictive value of AUCEM for clinical pregnancy in subgroup of women without coasting (AUC = 0.494, p > .05). In conclusion, neither coasting nor the high endometrial estrogen exposure was found to have detrimental effect on endometrial receptivity and cycle outcome in PCOS.

Objectives: To determine the predictive value of antral follicle diameter variance within each ovary for ovarian response in cases with normal ovarian reserve tests., Methods: This is a prospective observational study. One hundred and thirty nine infertile women who underwent ART in IVF-ICSI unit of Zeynep Kamil women and children's Health Training and research hospital between January 2017 to June 2017 were recruited. Blood samples were collected on day 2/day 3 for assessment of serum FSH and estradiol. Trans-vaginal sonography was done for antral follicle count. During antral follicle count, in order to determine antral follicle diameter variance, diameters of the largest and smallest follicles were recorded. Variance was calculated by subtracting the smallest diameter from the largest one. Following ovarian stimulation with antagonist protocol, poor response was determined in cases with total oocyte number≤3. Ovarian reserve tests and antral follicle diameter variance were utilized to predict cases with poor response in women with normal ovarian reserve., Results: Antral follicle diameter variance both in right (AUC=0.737, P<0.001) and left (AUC=0.651, P<0.05) ovaries significantly predicted poor ovarian response. Variance>3.5 mm was found to have 75% sensitivity to predict poor response. Basal serum FSH with estradiol levels and AFC failed to predict poor response (P>0.05). Other significant predictors for poor response were day 5 estradiol level and estradiol level at trigger day (P<0.05). In multivariate regression analysis, both AFC and antral follicle diameter variance in the right ovary were found to be significantly associated with clinical pregnancy, on the other hand peak estradiol concentration and antral follicle diameter variance in the right ovary were significantly associated with poor response., Conclusion: Antral follicle diameter variance may be utilized to predict poor ovarian response in cases with normal ovarian reserve., Competing Interests: The authors declare no conflict of interest., (© Georg Thieme Verlag KG Stuttgart · New York.)

Aim: The aim of this study was to compare serum folate, vitamin B12, 25-OH vitamin D, and calcium levels between pregnants with and without fetal anomaly of neural tube origin., Methods: One hundred seventy-eight pregnants were recruited for this study. Pregnants with and without sonographically detected fetal anomaly of neural tube origin were compared in terms of serum folate, vitamin B12, 25-OH vitamin D, and calcium levels., Results: There were significant differences between groups with regard to age, serum 25 OH vitamin D, 1,25 OH vitamin D, folate, calcium, and B 12 levels. Multivariate regression analyses revealed significant associations between the serum 25 OH vitamin D level, age, and the neural tube defect (NTD)., Conclusions: Vitamin D and the age of pregnants were significantly associated with the NTDs.

To compare the effect of the different protocols in patients receiving in vitro fertilization treatment due to poor ovarian response. Seventy-seven of the patients included in the study were treated with gonadotropin (450 IU) + GnRH antagonist (group 1), 84 of the patients were treated with gonadotropin (450 IU) + microdose GnRH analog (group 2), and 53 of the patients were treated with clomiphene citrate (100 mg/day) + gonadotropin (300 IU) + GnRH antagonist (Group 3). In assessing total gonadotropin dosage, patients in Group 3 detected significantly less gonadotropin as compared to the other two groups (p < .001). Group 1 were superior to the other two groups with respect to retrieved oocytes, meiosis II oocytes and number of embryos obtained at the end of the treatment. As for the evaluation of clinical pregnancy, although the highest pregnancy rate was in Group 3, this finding was not of statistical significance. Although increasing the dosage of gonadotropins for ovarian hyper stimulation treatment in patients with poor ovarian response is beneficial with respect to retrieved oocytes, meiosis II oocytes and number of embryos, the increased dosage does not provide a statistically significant increase in clinical pregnancy rates.

Background: There are very few biomarkers available to diagnose cases with premature ovarian failure. Some complete blood count parameters have been introduced to be diagnostic biomarkers for several disorders associated with inflammatory process. Due to the evidence that indicated chronic inflammatory process to be underlying pathophysiology in premature ovarian insufficiency (POI), we aimed to assess the predictive value of complete blood count parameters for POI diagnosis., Method: A total of 96 women diagnosed to have premature ovarian failure were compared with 110 otherwise healthy women in terms of some basal hormone levels and complete blood count parameters., Results: Mean age was similar between groups. Neutrophil/lymphocyte and mean platelet volume/lymphocyte ratios were significantly higher in group with POI (P < .001, P < .003, respectively). In group with POI, there were significant correlations between anti-Mullerian hormone and follicle stimulating hormone (r = -.30, P <.05), anti-Mullerian hormone and white blood cell count (r = .23, P < .05). Mean platelet volume/lymphocyte ratio significantly predicted cases with POI (AUC = 0.607, %95 CI: 0.529-0.684; P < .001)., Conclusions: Neutrophil/lymphocyte and mean platelet volume/lymphocyte ratios are elevated in POI. There have been some controversies about the value of neutrophil/lymphocyte in POI diagnosis. We suggest mean platelet volume/lymphocyte ratio as a new biomarker in early POI because it is cheap and easily accessible compared to anti-Mullerian hormone., (© 2017 Wiley Periodicals, Inc.)

Aim: The aim of this study was to introduce a modified form of fertility preserving approach in cases with placenta percreta., Methods: Eleven pregnant women with anterior placenta previa and suspected to have placenta percreta underwent cesarean section between 2015 and 2016 in Zeynep Kamil Women and Children's Health Training and Research Hospital. In all cases, following confirmation of placenta percreta diagnosis, a modified minimal invasive form of uterine preserving surgery was performed., Results: During the present study period, 11 pregnant women who were confirmed to have placenta previa and placenta percreta underwent modified form of segmental resection. In all cases, modified form of segmental resection was successful except for the two cases. There were significant statistical differences between pre-postoperative hemoglobin and hematocrit levels (p = .003). There was a significant correlation between the volume of resected segment and number of transfusions (r = .760, p = .047). Postoperative blood transfusion was not needed in 4 cases. No maternal mortality or other postoperative complication was observed in any case., Conclusion: A modified minimal invasive form of uterine preserving surgery seems to be safe and result in more cosmetic results with minimal blood loss.

Partial rotation of the uterus not more than 45 degrees to the right is considered to be normal. Since all cases are not reported, the incidence of uterine torsion in pregnancy is not known exactly. In the literature, there have been reports of cases with uterine torsion ranging from 45 to 720 degrees. This is a case report of uterine torsion of 720 degrees with accompanying bladder torsion, developing after two caesarean sections, and developing of uterine atony after the operation.

Aim: Is there any relationship between estrogen and progesterone concentrations during assisted reproductive technology (ART)? Which hormone is the main determinant of impaired endometrial receptivity?, Methods: This study was conducted from July to December 2016 at the in vitro Fertilization/Intracytoplasmic Sperm Injection unit at Zeynep Kamil Women and Children's Health Training and Research Hospital. A total of 289 women who underwent ART were prospectively screened and areas under the curve of temporal estrogen (AUCEM) and progesterone measurements (AUCPM) were calculated for each participant. Women were included if they had regular menstrual cycles, normal serum prolactin levels and had not received hormone treatment within three months. ART was indicated in all patients for unexplained infertility. Patients were divided into two groups: with (n = 90) and without (n = 199) embryo implantation. The relationship between the two AUCs and ART success was assessed in terms of embryo implantation and clinical pregnancy., Results: Implantation was successful in 90 (31.1%) women, and a fetal heart rate was detected in 83 (28.7%) cases. There was a significant correlation between AUCEM and AUCPM (r = 0.525, P < 0.001). Multivariate regression analysis showed significant associations between failure of implantation, lack of clinical pregnancy and AUCEM (beta coefficient = 0.311, P < 0.001; beta coefficient = 0.297, P < 0.001, respectively) after adjusting for AUCPM., Conclusion: Our data showed that the degree of endometrial estrogen exposure is the main factor functioning as a detrimental effect of ovarian stimulation on endometrial receptivity., (© 2017 Japan Society of Obstetrics and Gynecology.)

Objective: To compare embryo transfer (ET) technique based on catheter rotation during its withdrawal in cases with unexplained infertility in a prospective, randomized trial (NCT03097042)., Methods: Two hundred intracytoplasmic sperm injection (ICSI) patients undergoing ET with cleaving or blastocyst-stage fresh embryos were randomized into 2 groups: cases with (n = 100), and without (n = 100) catheter rotation during its withdrawal. Groups were matched for age and some clinical parameters. A soft catheter was used to transfer a single embryo with catheter rotation during its withdrawal in the study group and without rotation in the control. The use of a stiff catheter or tenaculum was not needed in any case. Groups were compared in terms of cycle characteristics and clinical pregnancy rates., Results: Pregnancy rate was significantly higher in the study group (41 vs. 26%, p = 0.04). Clinical pregnancy rate was also significantly higher in the study group (39 vs. 25%, OR 1.9 [1.1-3.5], p = 0.05). On the other hand, the ongoing pregnancy rate was similar between the 2 groups (33 vs. 23%, p = 0.2)., Conclusion: Catheter rotation during its withdrawal may be associated with increased pregnancy and clinical pregnancy rates; however, the difference in ongoing pregnancy rates did not reach statistical significance., (© 2018 S.

Objective: To describe the new surgical technique and report the safety and feasibility of vaginally-assisted laparoscopic sacrohysteropexy (VALSH)., Materials and Methods: Thirty-three women with stage 3 or more uterine prolapse underwent VALSH operation. Patients were followed up for 12 months for mesh-related complications and improvements of symptoms. The operation had three sections; 1 st laparoscopic, 2 nd vaginal, 3 rd laparoscopic., Results: The mean age, gravidity, and parity of the study population were 46.5 years (range, 25-68 years), 4.3 (1-9), and 2.9 (1-6), respectively. The mean duration of operation was 59.5 min (range, 20-120 min). There were significant differences between the pre- and post-operative values of pelvic organ prolapse quantification parameters, which were favorable in the latter evaluation (p<0.001); total vaginal length was preserved after surgery (p>0.05)., Conclusion: VALSH is a safe and minimally-invasive procedure in uterovaginal prolapse, with favorable anatomic and functional outcomes at 12 months post-operatively., Competing Interests: Conflict of Interest: No conflict of interest was declared by the authors.

Objective: In this study, we aimed to assess the acute alterations on some features of fetal heart rate (FHR) tracings in third trimester pregnancies., Methods: Data of FHR tracing records were obtained from 79 otherwise healthy pregnant women aged between 18 and 41. Among 79 women, 39 were nonsmokers while the remaining were chronic smokers (six or more cigarettes per day, with an average of 10 cigarettes per day). The baseline of tracings, the number of accelerations and decelerations of FHR, as well as the FHR mean, standard deviation, short-term variability of FHR were all calculated for each participant. The results of smokers and nonsmokers, then the results of smokers before and after smoking were compared., Results: Comparison of some demographic and FHR tracing characteristics between smoker and nonsmoker groups indicated significantly decreased variability in smoker group. All FHR tracing characteristics were compared before and, immediately after cigarette smoking and revealed significantly higher mean baseline, lower variability and acceleration after smoking a cigarette., Conclusion: Even in a short time period, smoking is associated with some changes in FHR monitorization characteristics, detailed analyses of these changes may clarify the pathophysiology of smoking associated perinatal outcome.

Aim: The aim of this study was to assess the predictive value of serum substance P (SP) concentrations on oocyte maturation and clinical pregnancy., Methods: Ninety-three women with unexplained infertility underwent intracytoplasmic sperm injection (ICSI) cycles. Antagonist protocol was started for each participant and at the day of oocyte pick up, serum samples were obtained from each participant to assess SP concentrations, and these concentrations were utilized to predict mature/total oocyte ratio and clinical pregnancy., Results: SP concentration was a significant predictor for mature/total oocyte ratio > 0.75 and clinical pregnancy. In correlation analyses, maturation index was significantly correlated with FSH (r= -0.226, p = 0.03), estradiol (r = 0.239, p = 0.021), peak estradiol (r = 0.414, p < 0.001), and substance P (r = 0.796, p < 0.001). In multivariate analyses, number of immature (beta coefficient = -0.379, p < 0.001), mature oocyte (beta coefficient = 0.473, p < 0.001), SP concentration (beta coefficient = 0.723, p < 0.001) and maturation index (beta coefficient = -0.387, p = 0.003) were significantly associated with clinical pregnancy., Conclusion: SP concentrations at the day of oocyte pick up may be used to predict clinical pregnancy and may be an indirect indicator for cycle outcome in assisted reproductive technology (ART).

Objective: To determine some major characteristic differences between two consecutive successful and unsuccessful intracytoplasmic sperm injection (ICSI) cycles in poor responders., Materials and Methods: Sixty women with poor ovarian response as determined using the Bologna criteria underwent ICSI cycles following an unsuccessful trial. Some parameters of both cycles including age, body mass index (BMI), serum follicle-stimulating hormone (FSH) and estradiol levels, antral follicle count, gonadotropin dosage, duration of stimulation, antagonist starting day, duration of antagonist administration, endometrial thickness at trigger day, number of total and fertilized oocytes, embryo transfer day, number of embryo cells, and fertilization rate were compared in the same patients to identify predictors of cycles with clinical pregnancy., Results: The mean age, BMI, serum FSH, estradiol concentrations, and antral follicle count were 35.9 years (range, 30-42 years), 25.9 kg/m 2 (range, 18.4-33.5 kg/m 2 ), 10.9 IU/mL (range, 7-13 IU/mL), 52.9 pg/mL (range, 11.6-75 pg/mL), and 4.7 (range, 2-10), respectively. A comparison of cycle characteristics showed a significantly higher total number of mature and fertilized oocytes in successful cycles. The fertilization rate was also significantly higher in cycles with clinical pregnancy. Early initiation of antagonist was shown to result in favorable outcomes. A comparison of embryo characteristics showed that transfer of higher-stage embryos and embryos with higher numbers of cells had a significant impact on cycle outcomes., Conclusion: Our comparison of parameters of failed and successful ICSI cycles in poor responders revealed significantly earlier antagonist initiation, higher total number of mature and fertilized oocytes, fertilization rate, and significantly higher stage of embryo development and cell numbers at transfer in cycles that resulted in clinical pregnancy., Competing Interests: Conflict of Interest: No conflict of interest was declared by the authors.

Objectives: This study was conducted to compare pregnancy outcomes of early-middle adolescent, late adolescent and adult women., Material and Methods: The study focused on early-middle adolescent (n = 145), late adolescent (n = 1655) and adult (n = 1585) women who gave birth during 2014 through 2017, utilizing data obtained from the Zeynep Kamil Women and Children's Health Training and Research Hospital. Pregnancy outcomes were determined according to the rates of preg¬nancy complications, including method of delivery, birth weight, as well as the rate of newborn intensive care admissions., Results: Comparisons between the studied groups for various pregnancy complications showed highest rates of pre¬term deliveries (PD), preterm premature rupture of membranes (PPROM) and neonatal intensive care unit admission in early-middle adolescent group, whereas the highest cesarean section rates were observed in the adult group (p < 0.001)., Conclusions: Analysis of the data revealed that adolescent pregnancy, especially the early-middle adolescent pregnancies, is associated with increased risks of adverse pregnancy outcomes.

Objective: To assess whether the area under the curve of temporal estradiol measurements (AUCEM) during cycles of assisted reproductive technology (ART) can be used to predict failure of implantation and clinical pregnancy., Methods: In a prospective study, women aged 24-39years undergoing ART at a center in Turkey were enrolled between January and December 2014. Eligible patients had a regular menstrual cycle, normal levels of serum prolactin, and no hormone treatment within the past 3months. The area under the curve of the time course of estradiol measurements was calculated for each participant, and assessed for its ability to predict successful implantation., Results: Among 282 participants, 109 (38.6%) women had successful implantation. There was a significant difference between the two groups of women in AUCEM, estradiol per day (AUCEM divided by duration of stimulation), and endometrial thickness on the day of human chorionic gonadotropin administration (P<0.05 for all)., Conclusion: The area under the curve of estradiol measurements during ART cycles might be useful for predicting failure of implantation and clinical pregnancy., (Copyright © 2016 International Federation of Gynecology and Obstetrics.

Leiomyomas are benign neoplasms that can develop wherever smooth muscle is present. Primary leiomyomas of the ovary originate from smooth muscle cells of ovarian tissue and are rare, solitary tumors. Approximately 70 cases have been reported. They usually present in premenopausal women. The present case is a report of left ovarian leiomyoma in a postmenopausal woman., Competing Interests: Conflict of Interest: None declared.

Extrauterine endometrial stromal sarcomas (ESSs) are quite rare tumors, and vagina is an unusual site for these tumors. This paper presents a very rare pathological entity of primary vaginal ESS. A 46-year-old woman with a complaint of postcoital vaginal bleeding, low abdominal pain, and constipation was admitted to the clinic. She had a mass of seven cm in size, located in the posterior fornix detected on physical examination. The preoperative biopsy showed ESS, surgical material, and evaluation of an endometrium confirmed the diagnosis of primary vaginal ESS. She underwent total abdominal hysterectomy, bilateral salpingo-oophorectomy, and partial vaginectomy. The diagnosis of ESS performed by pathologic and immunohistochemical evaluation was: caldesmon (-), actin (-), desmin (-). CDIO (+), ER (+), PR (+), and vimentin (+). There was no ESS lesion in the endometrium. The patient was free of tumor for 22 months after the surgery without any additional therapy. In this study, the authors report the sixth case of primary vaginal ESS in the literature and aim to discuss diagnostic criteria and management protocols in the light of the literature.

Nabothian cysts are common and silent retention cysts of the uterine cervix with no particular intervention required. It is quite rare to reach a size of more than 4 cm and it is a diagnostic dilemma to differ it from adenoma malignum. We report a case of a woman with 38 weeks of gestation presented to the maternity unit with labour pain and protruding cystic mass (60x70 mm) out of the vagina. Simple drainage was performed to allow the vaginal delivery. She delivered 4130 grams, 9-10 Apgar, male baby by spontaneous vaginal delivery. The patient's and the newborn postpartum course was uneventful. Gynaecologic examination revealed a persisting cystic mass in the cervix (40x50 mm) two months after the delivery. We performed a total excision of the cyst to confirm the pathologic diagnosis. This paper is the first report of nabothian cysts obstructing labour passage. In the view of this case, we aimed to discuss cervical cystic masses and a review of the literature.

Objective: Recurrent pregnancy loss is often defined as three or more consecutive pregnancy losses but there are no strict criteria for initiation of investigations after a miscarriage. We compared the frequency of uterine anomalies diagnosed by hysteroscopy following one, two and three or more miscarriages., Study Design: In our study 151 patients underwent diagnostic hysteroscopy following a missed or an incomplete abortion. Uterine septum, subseptum, arcuate uterus, and uterine hypoplasia are classified as congenital uterine anomalies and polyps, synechia, and submucous myomas are classified as acquired uterine abnormalities., Results: 151 Patients were enrolled in the study. The pregnancy numbers of the patients varied between 1 and 12. Sixty nine (46%) of the patients had one miscarriage, 42 (28%) had two miscarriages and 40 (26%) had three or more miscarriages. Diagnostic hysteroscopy revealed normal uterine cavity in 61.1% of the patients, congenital uterine anomalies in 20.4% and acquired uterine pathologies in 18.5%. Among the congenital anomalies, 14 (9.3%) were uterine septum, 10 (6.6%) were subseptate uterus, 4 (2.6%) were arcuate uterus and 3 (1.9%) were uterine hypoplasia. Among acquired abnormalities 14 (9.3%) were uterine synechia, 12 (7.9%) were endometrial polyps, and 2 (1.3%) were submucous myoma. Among patients who had one miscarriage 64.1% had a normal uterine cavity, 18.2% had congenital abnormalities and 17.7% had acquired uterine pathologies. Of patients with two miscarriages, 52% had a normal uterine cavity, 21.9% had congenital anomalies and 26.1% had acquired uterine pathology. In the three or more miscarriage group, 58.4% had normal uterine cavity, 25.3% had congenital anomalies, and 16.3% had acquired uterine pathology. We did not find any statistically significant difference between the number of miscarriages and pathologic diagnostic hysteroscopy findings., Conclusions: Post-abortion office hysteroscopy is a simple and efficient tool in the early diagnosis of congenital and acquired uterine pathologies. Diagnostic hysteroscopy can be performed after the first miscarriage in order to determine congenital and acquired uterine pathologies, with regard to the patient's age and anxiety level., (Copyright © 2011 Elsevier Ireland Ltd.
