OBJECTIVE To examine interleukin-12 (IL-12), IL-18, IFN-γ, intracellular adhesion molecule-1 (ICAM-1), leukemia inhibitory factor (LIF), and migration inhibitory factor (MIF) levels in precisely-timed blood and endometrial tissue samples from women with idiopathic recurrent pregnancy loss (RPL). DESIGN Case-control study. SETTING University hospital. PATIENT(S) Twenty-one women with RPL and 20 women with proven fertility (controls). INTERVENTION(S) Primary endometrial cells and blood samples during the midsecretory phase (days 19-23). MAIN OUTCOME MEASURE(S) Detection of IL-12, IL-18, IFN-γ, ICAM-1, LIF, and MIF via enzyme-linked immunosorbent assay in both blood and endometrial tissue samples. RESULT(S) The blood and tissue levels of IL-12, IL-18, and IFN-γ were statistically significantly higher, and the blood and tissue levels of LIF and MIF were statistically significantly lower in patients with RPL. Only the level of tissue ICAM-1 was higher in patients with RPL. There was a strong correlation between blood and tissue level measurements of IL-12, IL-18, LIF, and MIF. CONCLUSION(S) Our findings support the hypothesis that inflammatory processes may contribute to pregnancy loss, possibly through their role in implantation. We found that blood and tissue levels of IL-18, LIF, and MIF, and tissue levels of IL-12, IFN-γ, and ICAM-1 have statistically significant prognostic relevance.

OBJECTIVE The aim of this randomized controlled trial (RCT) was to investigate whether IVF outcomes would differ between patients with POR who received three different gonadotropin doses with or without the addition of letrozole during ovulation stimulation. STUDY DESIGN Only those who fulfilled two of the three Bologna criteria were included to the study. 95 patients met the inclusion criteria and agreed to participate in the study. In the first group, 31 patients were treated with 450IU gonadotropins. In the second group, 31 patients were treated with 300IU gonadotropins. The third group comprised 33 patients and was treated with 150IU gonadotropins in combination with letrozole. RESULTS The results indicate that differences in doses of hMG and rFSH in patients with POR result in a similar number of retrieved MII and fertilized oocytes, similar fertilization rates, number of transferred embryos, implantation, cancelation, chemical, clinical, and ongoing pregnancy rates. CONCLUSIONS Increasing the dose of gonadotropins during ovulation stimulation is an intuitively appealing approach when the patient is a poor responder. However, increasing the dose does not necessarily improve the reproductive outcome. Using a mild stimulation with addition of letrozole was as effective as stimulation with higher doses of gonadotropins alone in this patient population.

BACKGROUND Persistent left superior vena cava (PLSVC) is a variant of systemic venous return which is observed in 0.3% of autopsies in the general population and in 4-8% of patients with congenital heart disease. AIMS To evaluate associated cardiac, extracardiac and chromosomal anomalies in prenatally diagnosed cases of PLSVC and to review their outcome. STUDY DESIGN Retrospective comparative study. METHODS The data of patients with a prenatal diagnosis of PLSVC between May 2008 and January 2013 were reviewed retrospectively. RESULTS Data of 31 cases were reviewed. Fifteen (48.4%) cases were associated with cardiac defects and 17 (54.8%) cases had associated extracardiac sonographic or postpartum findings. Two fetuses had karyotype anomalies. Outcome was significantly more favorable in cases not associated with cardiac defects in comparison to those associated with cardiac anomalies (84.6% vs. 33.3%, p=0.009). All cases with isolated PLSVC survived, while among the cases associated with extracardiac anomalies, with cardiac anomalies and with both extra-cardiac and cardiac anomalies, the survival rate was 75%, 50% and 22.2%, respectively. The most frequent group of cardiac anomalies associated with PLSVC was septal defects and VSD was the most common heart defect individually, being observed in nine fetuses. CONCLUSION Prenatally diagnosed PLSVC is associated with cardiac and extracardiac anomalies in the majority of cases. Outcome is significantly worse if PLSVC is associated with a cardiac defect, and the prognosis is excellent in isolated cases.

Abnormal uterine bleeding (AUB) is a substantial cause of ill health in women worldwide. In this study, our aim was to evaluate the effectiveness of endometrial ablation using a modified urologic resectoscope along with tranexamic acid in AUB. Sixty patients were enrolled in this study. All patients underwent resectoscopic surgery. Patients were randomly divided into two groups. Group 1 (n = 30) received 500 mg of tranexamic acid. Group 2 (n = 30) served as the control group and underwent surgery without the administration of tranexamic acid. Total pictorial blood loss assessment chart (PBAC) scores were significantly lower postoperatively (152.14 ± 9.65 versus 6.6 ± 0.90; P < 0.001). When stratified by the administration of tranexamic acid, the number of patients with a postoperative day 1 PBAC score ≤15 was higher in the tranexamic group (19 versus 13), whereas the number of patients with a post operative day 1 PBAC score >15 was lower in the tranexamic group (11 versus 17), but the differences were not statistically significant (P > 0.05). AUB is a complex disease that may need repeated treatments. In expert hands, the treatment rate of resectoscopic surgery seems acceptable. However, some patients may require additional interventions, like repeated surgery, hysterectomy, or a drug therapy in the long run. Introduction of tranexamic acid as a potential adjunct to rollerball endometrial ablation may present an interesting option that requires additional well-designed studies before firm conclusions can be made.

Objective: Fetal structural malformations affect approximately 2-3% of all pregnancies. Only focusing on trisomy screening in first trimester and deferring the anatomic screening to second trimester may result with late detection of major anomalies that can be diagnosed earlier with careful examination. Material and Methods: This was a descriptive study of retrospective data that were obtained from all terminated single pregnancies due to ultrasonographic findings of major anomalies from 2011 to 2016 in our department. The study was based on a chart review and only abnormalities that were diagnosed before the 16th week were included. Results: Two hundred forty-four first trimester pregnancy terminations were performed. In total, 273 anomalies were detected in the 244 patients. Cranial NTD comprised 32% of all anomalies (n=89). Fifteen percent of anomalies (n=41) needed detailed anatomic scanning for early diagnosis. Conclusion: In this study, we presented the number and percentage of our early diagnosed anomalies by years, as well showed our diagnostic performance for specific anomalies such as atrioventricular septal defect during a 5-year period. The study provides valuable information for future studies in Turkey and shows the need for an anatomic scan protocol while performing aneuploidy screening during early gestation.

OBJECTIVE To elucidate the immunohistochemical (IHC) differences of endometrioma tissues that may have the potential to progress to ovarian clear cell carcinoma (OCCC) by using KRAS, HNF1β, PIK3CA, PPP2R1A, and ARID1A as biomarkers. STUDY DESIGN This is a retrospective clinical study, which was conducted in an university hospital. The groups comprised 14 patients with endometrioma resection who later developed OCCC (non-healthy endometrioma-case group) and 66 patients with endometrioma resection who did not develop ovarian cancer in subsequent follow-ups (healthy endometrium-control group). IHC staining with KRAS, HNF1β, PIK3CA, PPP2R1A, and ARID1A antibodies was performed in paraffin blocks of endometriomas obtained in both groups. For KRAS, PIK3CA, PPP2R1A, and ARID1A, cell staining intensity on a scale from 0 (negative) to 3 (strongly positive), and for HNF1β, the percentage of stained cells (0-5) and the intensity of staining (0-3) were scored. RESULTS KRAS, HNF1β, PIK3CA, PPP2R1A, and ARID1A were overexpressed in the case group samples compared with the endometrioma samples in the epithelial cells, and ARID1A and KRAS in the stroma were overexpressed in the case group samples compared with the matched control samples. CONCLUSIONS KRAS, HNF1β, PIK3CA, PPP2R1A, and ARID1A immunostaining scores in endometriomas previous to OCCC were significantly different than in endometriomas with no malignancy occurring in subsequent follow-ups, and were single predictors of OCCC. Hence, immunostaining with these biomarkers may be a method of identifying patients with endometrioma who have the potential to develop OCCC.

Pectus excavatum (PE) is the depression of the lower part of manubrium sterni and xiphoid process. The main problem of PE depends on the cardiopulmonary morbidity caused by the narrowing of the thoracic space. To date, prenatal diagnosis of this deformity has been reported only once and was associated with Down syndrome. We present another case which we diagnosed as PE during a second-trimester fetal anatomic scan. The pectus severity index is used for these patients in postnatal life; however, prenatal adaption of this index is reported for the first time in our case.

Objective: To evaluate fetal aortic Doppler for the prenatal diagnosis of hemoglobinopathies in the first trimester of pregnancy. Materials and Methods: Between January and November 2014, a total of 108 patients were enrolled in the study. The couples were carriers of either alpha/beta thalassemia, sickle cell disease or combined carriers of these and were admitted to Çukurova University Faculty of Medicine, Department of Obstetrics and Gynecology Prenatal Diagnosis Center. One hour before the chorionic villus sampling (CVS), patients were evaluated using fetal aortic Doppler. Pulsatility index, peak systolic velocity, and heart rate were noted. Results: There were no statistically significant differences in Doppler indices between different groups of CVS results when compared with the healthy controls. Conclusion: Fetal aortic Doppler investigation was found to be ineffective for the prenatal diagnosis of hemoglobinopathies.
