    HELLP syndrome is characterized by hemolysis, elevated liver enzymes and thrombocytopenia. With a incidence of 0.1%-0.8% it is known to be effected by genetic predisposition. Unlike preeclempsia multiparity increases the risk of HELLP syndrome. Diagnosis is made by the classic clinical triad. Thrombocyte counts are especially important for classification of the disease. When making a diagnosis, severe preeclempsia, acute fatty liver of pregnancy, hemolytic ureamic syndrome and thrombocytopenic thrombotic purpura should be always be kept in mind for differential diagnosis. HELLP syndrome has several complications , including but not limited to; disseminated intravascular coagulopathy, acute renal failure, pulmonary edema, liver rupture and hematoma and retinal detachment. Suggested treatment modality consists, stabilization of blood pressure and magnesium sulfate infusion. Then evaluation of fetal status and planning delivery method and time if maternal status remains unstable. If pr...

    Objective: The present study aims to assess the success of controlled ovarian stimulation in intrauterine insemination cycles stimulated by recombinant-FSH and Clomiphene citrate for either mono- or bi-follicular development. Methods: We assessed 870 infertile patients treated with controlled ovarian stimulation in intrauterine insemination cycles at a university-based infertility clinic between January 2012 and December 2017. We compared the cycles stimulated by clomiphene citrate and recombinant-FSH in two set-ups; mono- and bi-follicular development. The main outcome measure was the clinical pregnancy rate per cycle. Results: The demographic and cycle parameters were similar between the groups, except for endometrial thickness on the day of hCG administration, which was higher in the recombinant-FSH group than the clomiphene citrate group. The overall clinical pregnancy rates in clomiphene citrate and recombinant-FSH groups were 9.8% and 10.3%, respectively (p=0.940). Regarding t...

    Pompe disease is an autosomal-recessive disorder caused by acid alpha-glucosidase deficiency due to mutations in the GAA gene. There are two forms of the disease: infantile-onset Pompe disease and late-onset Pompe disease. The worldwide incidence of both forms of the disease is commonly reported to be 1 in 40,000. Adult patients are affected by limb-girdle muscular weakness and respiratory insufficiency. Enzyme replacement therapy with alglucosidase-alpha is available since 2006. There is little knowledge about pregnant woman with Pompe disease. These women should be considered as high-risk pregnant women. Here, we aim to present Cesarean delivery and postpartum management of a case with an interrupted enzyme replacement therapy during pregnancy.

    Triptorelin 0.2 mg and leuprolide 1 mg subcutaneous injections for triggering final follicular maturation were compared in patients with a high risk for ovarian hyperstimulation syndrome (OHSS). Infertile patients treated with GnRH antagonist protocol between January 2014 and March 2016 were recruited. Patients with high serum oestradiol levels on HCG day (>3000 pg/ml) indicating a risk of OHSS consisted of the study groups (A and B). Patients with serum oestradiol levels less than 3000 pg/ml consisted of the control group (C). A single injection of 0.2 mg triptorelin, 1 mg leuprolide and 10000 IU HCG were administered for final oocyte triggering in groups A (n = 63), B (n = 74) and C (n = 131), respectively. Demographic parameters were comparable between the groups. No cases of severe or moderate OHSS occurred in any group. The clinical pregnancy rates were 31.7%, 37.8% and 32.8% in groups A, B and C, respectively. Both injections had comparable efficacy in clinical outcome and OHSS risk. Regardless of preferred drug, GnRH agonist trigger for final oocyte maturation seems to be safe for patients with high OHSS risk, and can be safely used in fresh embryo transfer cycles.

    ABSTRACT Occult hernia is an under-diagnosed condition in women with chronic groin pain. Labium majus is an important landmark for conditions of round ligament and direct inguinal hernias. The association of labia majora and abdominal structures through the round ligament should be considered while evaluating labial conditions.

    The aim of the present study was to compare follicular fluid (FF) levels of norepinephrine (NE) and dopamine (DA) in polycystic ovary syndrome (PCOS) and non-PCOS patients who underwent in vitro fertilization (IVF). Forty-seven PCOS patients (study group) and 61 patients with male factor infertility (control group) who underwent IVF using GnRH agonist protocol were recruited. Concentrations of NE and DA were measured in FF specimens of all patients. Demographic characteristics were comparable between the groups. Significantly higher levels of NE were measured in FF of PCOS patients (median: 61.05 nmol/l) compared to those with male infertility (median: 49.82 nmol/l). Similarly, significantly higher levels of DA were measured in FF of PCOS patients (median: 23.70 nmol/l) compared to those with male infertility (median: 18.28 nmol/l). In conclusion, the FF concentrations of both catecholamine are increased in PCOS patients when compared to non-PCOS patients.

    The aim of this study was to assess the diagnostic accuracy of hysterosalpingography (HSG) on tubal patency (TP) and to determine whether performing laparoscopy (LS) can change the original management strategy based on HSG findings. Records of all infertile couples (n = 1298) treated at a university-based infertility clinic between January 2002 and June 2010 were reviewed. All patients who had both HSG and LS testing (n = 264) were included in the study. HSG was performed in an attempt to rule out tubal and/or uterine pathologies. All patients included in the study were evaluated with LS not more than 12 months after HSG. The validity of HSG screening for TP was calculated as 84.1%. The positive and negative predictive values of HSG were 54.6% and 98.3%, respectively. The sensitivity of HSG was higher in patients with distal tubal occlusion than in patients with proximal tubal occlusion (69.8% [44/63] vs 46.7% [28/60], respectively; P = 0.011). The rates of management plan change in patients with bilateral TP, unilateral tubal occlusion and bilateral tubal occlusion were 2.8%, 12.2% and 32.4%, respectively (P = 0.000). Patients with both unilateral tubal occlusion and bilateral tubal occlusion on HSG should be reevaluated with LS to determine the appropriate management strategy.

    To assess clinical and histopathologic risk factors for reoperation after laparotomic myomectomy due to leiomyoma recurrence. A case-control study was conducted of patients who underwent their first myomectomy for leiomyoma without receiving gonadotropin-releasing hormone analogues at Ankara University School of Medicine, Ankara, Turkey, between January 2000 and December 2004. Medical records and histopathologic samples were reviewed, and participants completed a telephone interview. Patients in the case group had undergone reoperation within 5 years; those in the control group had not required further surgery. There were 51 patients in the case group and 61 controls. The number of women who had given birth after the index surgery was lower among cases than controls (4 [7.8%] vs 13 [21.3%]; P=0.048), as was the median size of the largest leiomyoma removed (4 cm [range 3-10] vs 5 cm [range 3-25]; P=0.009). Reoperation was more likely among patients aged at least 40 years at index surgery (OR 1.10; 95% CI 1.18-7.78; P=0.021) and those with myxoid change (OR 2.04; 95% CI 1.07-55.41; P=0.043). The number of leiomyomas removed was negatively associated with reoperation (OR 0.30; 95% CI 0.58-0.93; P=0.012). Young age, removal of many or large leiomyomas, and pregnancy after myomectomy decreased reoperation risk, whereas myxoid change increased risk.

    To determine the effects of addition of different dosages of gonadotrophin releasing hormone agonist (GnRH-a) to routine luteal phase support (LPS) on implantation and pregnancy rates. Three hundred infertile couples who were treated by intracytoplasmic sperm injection and embryo transfer (ICSI-ET) following controlled ovarian stimulation (COS) with long luteal GnRH agonist protocol were enrolled. All women received 600 mg/day vaginal micronized progesterone plus 4 mg 17β estradiol for LPS starting from the day of oocyte retrieval. Patients (n=300) were randomized into three treatment groups. Group A (n=100) received leuprolide acetate 1 mg s.c. injection 3 days after ET in addition to routine LPS. Group B (n=100) received two sequential doses of leuprolide acetate 1 mg s.c. injections 3 and 6 days after ET in addition to routine LPS. Control group (n=100) received only the routine LPS. A total of 279 patients completed the study. The groups were comparable in terms of baseline demographic parameters including age, duration of infertility and day 3 levels of FSH and estradiol. The cycle parameters of the groups were also comparable regarding the E2 level on day of hCG, number of retrieved oocytes, number of day 3 embryos, number of embryos transferred, and endometrial thickness on both days of OPU and ET. The implantation rates were similar in between the Groups A, B, and control group (20.7% and 25.8% vs. 13.3%, respectively; P=.099). The clinical pregnancy rates and miscarriage rates were similar in between the groups. The ongoing pregnancy rates were 27.4% in control group, 36% in Group A and 42.9% in Group B (P=.093). The OHSS rates were comparable in between the groups. The multiple pregnancy rates were significantly higher in Groups A and B than in control group (12% and 17.9% vs. 4.2%, respectively; P=.014). The implantation, clinical pregnancy and ongoing pregnancy and multiple pregnancy rates seem to be increased with the addition of GnRH-a to routine luteal phase support.

    In this study, we aimed to determine whether human embryos secrete interleukin-1β (IL-1β) into culture media and its correlation with embryo grade and development. Culture media supernatants of 100 embryos obtained from 39 cycles of 38 patients and cultivated individually were collected 2 and 3 days after intracytoplasmic sperm injection (ICSI). IL-1β concentrations of samples were determined with ELISA and compared with embryo grades and blastomere numbers. Embryo grades and the amount of IL-1β they secreted were found not to be correlated (p:0.559). Numbers of blastomeres each embryo had at 2nd and 3rd days were found to be correlated with IL-1β secreted (p:0.00 and p:0.00, respectively). Mean amount of IL-1β secreted by the embryos from ejaculated sperm cycles were found to be significantly higher than that of embryos from TESE cycles (p:0.016). Patient age and etiology of infertility were not correlated with the amount of IL-1β secreted and embryo grade. In conclusion, preimplantation human embryos secrete IL-1β in their media in amounts correlated with their blastomere numbers.

    To investigate the relationship of the progesterone-to-estradiol (P/E2) ratio on the day of hCG administration with ongoing pregnancy rates in patients with normal ovarian reserve undergoing GnRH antagonist cycles. Observational cohort study including 129 women with normal ovarian reserve undergoing the GnRH antagonist protocol at the IVF unit of Ankara University School of Medicine. Receiver operating characteristics (ROC) analysis was performed to determine cut-off values for the P/E2 ratio detrimental to IVF/ICSI-ET outcomes. The ongoing pregnancy rate was the primary outcome measure. Groups were compared using the independent-samples Student's t-test, Mann Whitney and Chi-Square tests. Multivariate logistic regression analysis was used to study the association between the variables and the P/E2 ratio. The optimal cut-off value for P/E2 ratio in GnRH antagonist cycles was 0.48; ongoing pregnancy rates and live birth rates were found to be significantly higher in patients with P/E2 ratios≤0.48 than those with>0.48 (50% vs 22.4%, p=0.001 and 38.5% vs 19.7%, p=0.02, respectively). In logistic regression analysis, the P/E2 ratio was found to be an independent predictor for pregnancy, but the sensitivity (69%), specificity (61%) and overall accuracy (67%) were low as a predictor test for cycle outcome. Although a P/E2 ratio≤0.48 on the day of hCG administration was associated with significantly higher ongoing pregnancy and live birth rates, it has poor predictive value for cycle outcome in patients with normal ovarian reserve undergoing GnRH antagonist cycles.
