Abstract Objective: The purpose of this study is to investigate the role of serum anti-Müllerian hormone (AMH), follicle-stimulating hormone (FSH) and antral follicle count (AFC) for the prediction of clinical pregnancy rates (CPR) in women with polycystic ovary syndrome (PCOS) undergoing IVF treatment. Design: Prospective cohort study. Setting: University hospital. Patients: One hundred and fifty consecutive women with PCOS. Interventions: All women underwent controlled ovarian stimulation with long agonist protocol followed by IVF procedure. Outcomes of pregnant and non-pregnant groups were compared. Main outcome measure: CPR; AMH, FSH and AFC means and percentiles. Results: Fifty-one (34%) clinical pregnancies were observed in 150 women. Mean AMH was 6.7 ± 2.8 and 7.1 ± 4.3 ng/mL in pregnant and non-pregnant women, respectively (p = 0.594). The CPR were 27.8%, 35.0% and 37.8% in <25%, 25%–75% and >75% AMH percentiles, respectively (p = 0.656). There were also no significant difference in mean FSH and AFC between pregnant and non-pregnant women (p = 0.484 and p = 0.165, respectively). Conclusion: AMH, FSH and AFC are not predictive for CPR in women with PCOS undergoing IVF treatment. Mean AMH values were not significantly different between pregnant and non-pregnant women. Although CRP increased in parallel with the raise in AMH percentiles, this remained insignificant.

OBJECTIVE(S) To compare granulosa cell apoptosis in patients with unexplained infertility and tubal factor. Accelerated granulosa cell apoptosis may be the cause of unexplained infertility. STUDY DESIGN Setting was IVF-ET Unit of Cerrahpasa Medical Faculty, Istanbul University. GnRH analogs and gonadotropins were used for ovulation induction in patients with unexplained infertility (n=15) and tubal factor (n=15) undergoing in vitro fertilization and embryo transfer (IVF-ET) procedures. Following HCG injection and follicular aspiration, apoptosis of granulosa cells was assessed using the in situ DNA nick end labelling method and apoptosis rate was further determined by flow cytometry. Apoptosis rates were compared between two groups. Mann-Whitneys U-test and Students t-test were used for statistics. RESULTS Apoptosis rate was significantly higher in the unexplained infertility group (33.20 +/- 35.62% versus 10.10 +/- 17.23%). CONCLUSION(S) Granulosa cell apoptosis seems to have a role in the etiology of unexplained infertility.

In this study, a total of 647 vaginal discharge samples were examined. Ureaplasma urealyticum growth was seen in 68 samples (10.5%). The antibiotic sensitivity of 30 types of U.urealyticum was determined with the E-test and agar dilution method. With the agar dilution method, all types were sensitive to ciprofloxacin and ofloxacin (MIC 0.94 µg/ml), tetracycline (MIC 0.125 µg/ml) and doxycycline (MIC 0.125 and 0.190 µg/ml). Furthermore, with the agar dilution method, 18 types (60%) were resistant to roxithromycin and 12 (40%) were sensitive (MIC 12 µg/ml); 3 types (10%) were resistant to erythromycin and 27 (90%) were sensitive (MIC 12 µg/ml); 9 types (30%) were resistant to clarithromycin and 21 (70%) were sensitive (MIC 12 µg/ml), and all types were sensitive to azithromycin (MIC 14 µg/ml).

OBJECTIVE To present 13 cases of unruptured tubal ectopic pregnancies successfully treated with ultrasound-guided aspiration and local and systemic methotrexate (MTX) administration. DESIGN Case series. SETTING University hospital. PATIENT(S) Thirteen women with an unruptured tubal ectopic pregnancy. INTERVENTION(S) Transvaginal ultrasound-guided aspiration of the tubal ectopic pregnancy followed by MTX administration into the gestational sac (half of the calculated total dose of 25 mg/m(2)) and intramuscular injection (the remaining half of the calculated total dose of 25 mg/m(2)). MAIN OUTCOME MEASURE(S) Recovery of the patients, successful conservative treatment of the tubal ectopic pregnancies with preservation of the fallopian tubes. RESULT(S) Twelve (92%) of 13 women were successfully aborted, without need for salpingectomy or salpingostomy. CONCLUSION(S) Transvaginal ultrasound-guided aspiration of fetus followed by local and systemic methotrexate administration can be safely used to treat unruptured tubal ectopic pregnancies.

PURPOSE To investigate the efficacy of oral misoprostol administered to facilitate tandem application to the cervix as a part of brachytherapy in patients with cervical cancer. METHODS AND MATERIALS Eighty patients with cervical cancer who had been planned to undergo brachytherapy at Dr. Lütfi Kırdar Kartal Training and Research Hospital were evaluated in a double-blind, prospective, randomized trial. Patients were divided randomly into two groups of 40 patients. The first and second groups received 400 μg of misoprostol orally and placebo, respectively, 3 h before tandem application. The two groups were compared in terms of age, diameter of tumor, parity, age at first intercourse, amount of bleeding and pain at first tandem application, length of endometrial cavity measured by hysterometer, and size of Hegar dilators used for cervical dilatation. RESULTS Of all cases, 63.6%, 16.3%, 10%, 6.3%, 2.5%, and 1.3% were Stage IIB, IIIB, IIIA, IVA, IIA and IIC, respectively. Mean (±SD) age (range) was 49.3 ± 13.1 (25-83) years and 56.6 ± 13.2 (30-78) years in the study and control groups, respectively (p = 0.015). Age at first intercourse, diameter of tumor, parity, amount of bleeding at first tandem application, and length of endometrial cavity measured by hysterometer were not significantly different between the two groups. Pain score was significantly higher in the control group (p < 0.001). Application was significantly easier in the study group compared with controls (p < 0.001). Average size of initial Hegar dilators used for cervical dilatation was significantly higher in the study group compared with controls (p = 0.017). CONCLUSION Administration of misoprostol 400 μg orally for cervical ripening before tandem application facilitates the procedure, increases patient tolerability and comfort, and may decrease complication rates.

To determine clinically the fetal dose from irradiation of Hodgkins disease during pregnancy and to quantify the components of fetal dose using phantom measurements. The fetal dose was measured with phantom measurements using thermoluminescent dosemeters (TLDs). Phantom measurements were performed by simulating the treatment conditions on an anthropomorphic phantom. TLDs were placed on the phantom 41, 44, 46.5 and 49.5 cm from the centre of the treatment field. Two TLDs were placed on the surface of the phantom. The estimated total dose to all the TLDs ranged from 8.8 to 13.2 cGy for treatment with (60)Co and from 8.2 to 11.8 cGy for 4 MV photons. It was concluded that the doses in different sections were evaluated to investigate dose changes in different points and depths of fetal tissues in phantom. Precise planning and the use of supplemental fetal shielding may help reduce fetal exposure.

Abstract The aim of this study was to determine whether homocysteine (hcy) concentrations in embryo culture media correlate with pregnancy outcome in assisted reproductive technology (ART) cycles. Forty patients who underwent single embryo transfer at the infertility clinic of a tertiary care center were recruited for this case-control study. Spent embryo culture media from all patients were collected after single embryo transfer on day 3 (n = 40). Hcy concentrations in embryo culture media were analyzed by enzyme cycling method. Patients were grouped according to the diagnosis of a clinical pregnancy. Sixteen patients were pregnant while 24 patients failed to achieve conception. Mean Hcy levels in the culture media were significantly different between the groups (p < 0.003), as 4.58 ± 1.31 μmol/l in the non-pregnant group and 3.37 ± 0.92 μmol/l in the pregnant group. Receiver operator curve analysis for determining the diagnostic potential of Hcy for pregnancy revealed an area under the curve of 0.792 (confidence interval: 0.65–0.94; p < 0.05). A cut-off value of 3.53 μmol/l was determined with a sensitivity of 83.3%, and a specificity of 68.8%. Lower hcy levels were associated with a better chance of pregnancy and better embryo grades. Hcy may be introduced as an individual metabolomic profiling marker for embryos.
