Aim: The aim of this study was to determine the contribution of Shear Wave Elastography (SWE) to the diagnosis of polycystic ovarian syndrome (PCOS).Material and methods: Thirty-seven patients with PCOS diagnosis criteria were included in the study. Sixteen volunteer patients without hormonal disturbances and with normal menstrual cycles were evaluated as the control group. Gray scale ultrasonography (US) and SWE measurements in both ovaries were performed by a single radiologist who was blinded to the clinical and laboratory results.Results: The SWE measurements in PCOS group were 8.4±2.0 kPafor the right ovary and 9.4±3.9 kPa for the left ovary and in the control group 7.8±4.1 for the right ovary and 8.6±2.5 kPa for the left ovary. There was no statistically significant difference between the PCOS and the control group according to the SWE results (for right ovary p=0.356, for left ovary p=0.258, and total ovary p=0.293).Conclusions: The ovarian morphology isstill the most reliable imaging finding in the diagnosis of PCOS, although it is controversial especially among adolescents. Although the diagnostic efficacy of SWE is demonstrated in a variety of soft tissue lesions, we did not find any significant contribution of SWE to the diagnosis PCOS. Therefore, the promising value of elastography is yet to be defined for the diagnosis of PCOS.

Objectives: The success rate of methotrexate (MTX) therapy varies among tubal ectopic pregnancies. Common methylenetetrahydrofolate reductase (MTHFR) polymorphisms (C677T&A1298C) have been suggested to alter MTX effect. This study aimed to assess and compare MTX treatment failure rates with respect to MTHFR polymorphisms in trophoblasts of ectopic tubal pregnancies. Material and methods: A retrospective chart review of tubal ectopic pregnancies was conducted and 34 eligible cases were found. Paraffinized blocks of ectopic trophoblastic tissues were retrieved from the archives of pathology department. Common MTHFR polymorphisms were studied on microdissected trophoblastic tissues. Sixteen cases with history of failed MTX therapy (study group) and 18 control cases were compared for their pertinent clinical characteristics and common MTHFR polymorphisms (C677T&A1298) data. Results: In the study group, there were 8 (50%) C677T single nucleotide polymorphisms (SNP) and 9 (56.7%) A1298C SNP. Polymorphism rates were not found to be different between two groups for neither polymorphism (p > 0.05 for both). Number of compound heterozygotes was 3 (18.7%) in study group and 5 (27.7%) in controls (p = 0.693). In addition, MTHFR polymorphism presence seemed to have no effect on interval serum β-hCG concentration change in MTX-fail group (p=0.693). Conclusions: Our data implied that common MTHFR polymorphisms of ectopic trophoblastic tissue are not associated with MTX failure in patients with tubal pregnancies. Additionally, serum β-hCG concentration changes caused by MTX treatment and studied MTHFR polymorphisms are likely independent.

Infertility is one of the major health problems of our time. In fact, infertility is caused by many factors. Among these factors the effect of vitamin D levels of infertility are overlooked. The prevalence of vitamin D deficiency varies between 20% and 66.8% in different countries. In fact, vitamin D deficiency can lead to infertility both women and man. Lack of vitamin D in women with polycystic ovary syndrome in the study, uterine fibroids, as well as has been demonstrated over a relationship with a decrease in reserves. In males it has been suggested to affect sperm count and morphology. At the same time vitamin D levels may play a role in facilitating implantation. Even in studies in vitro fertilization has been shown to increase the success rate with the support of vitamin D. In this article, vitamin D deficiency and infertility issues were revised in light of the current articles.

Objective: To evaluate the pregnancy outcomes of patients who underwent appendectomy during pregnancy. Materials and Methods: Patients who underwent appendectomy between years 2010 and 2014 were retrospectively evaluated. All patients' pregnancy outcomes were followed-up by using university registry system and telephone interview. Patients were evaluated regarding age, gestational age, clinical and laboratory examinations, imaging studies, mean time interval between emergency department and operation, mean operative time, pregnancy outcome and pathologic results of the appendix. Results: Thirty-nine patients were included in the study. Sixteen of 39 patients were in the first, 15 of them in the second and 8 of them were in the third trimester of the pregnancy. Three patients underwent laparoscopic appendectomy and the rest underwent laparotomy. In pathologic evaluation of the appendix, seven patients (17%) had normal appendix, 4 patients had perforated appendix, one patient had neuro-endocrine tumor and rest of the patients had appendicitis. Two missed abortion occurred after operation, rest of the patients had live birth. Six of them were preterm and 31 had term birth. Twelve patients delivered through vaginal birth and the rest via caesarean section. Twenty patients were in the first half of the pregnancy (group 1) and 19 patients were in the second half of the pregnancy (group 2). There were no significant differences between the groups in operation time and mean time interval between emergency administration and operation. Conclusion: Delayed operation and negative appendectomy can cause adverse pregnancy outcomes. Expectant management in suspected cases may decrease negative appendectomy rates but can also lead to perforation. Computed tomography and MRI ought to be considered if ultrasonography is inconclusive. Tocolytic regimens can be administered to prevent threatened preterm labor. Obstetric indications were valid for delivery mode. Amaç: Gebeliğinde apendektomi yapılan hastaların gebelik sonuçlarının değerlendirilmesi.
