The comparision of effect of microdose GnRH-a flare-up, GnRH antagonist/aromatase inhibitor letrozole and GnRH antagonist/clomiphene citrate protocols on IVF outcomes in poor responder patients.

Abstract Purpose: To compare the effects of microdose GnRH-a flare-up, GnRH antagonist/aromatase inhibitor letrozole and GnRH antagonist/clomiphene citrate protocols on IVF outcomes in poor responder patients. Methods: Of 225 patients, 83 patients were in microdose flare-up group (Group 1), 70 patients were in GnRH antagonist/letrozole group (Group 2) and 72 patients were in GnRH antagonist/clomiphene citrate group (Group 3). Demographic and endocrine characteristics, the total number of oocytes retrieved, cancellation rate and clinical pregnancy rate were collected Results: Total dosage of gonadotropins (p = 0.002) and serum E2 levels on the day of hCG administration (p = 0.010) were significantly higher and duration of stimulations (p = 0.03) was significantly longer in group 1. The number of oocytes retrieved was significantly greater in group 1 and 2 when compare to those of group 3 (p = 0,000). There was a trend towards increasing cycle cancellation rates with GnRH antagonist/clomiphene citrate and GnRH antagonist/letrozole. Conclusion: Our finding suggest that the results of microdose flare-up protocol are better than other two used treatment protocols, in terms of maximum estradiol levels, number of mature oocytes retrieved, and cancellation rate and it still seems to be superior the ovarian stimulation regime for the poor responder patients.

Protective Effect of Platelet Rich Plasma on Experimental Ischemia/Reperfusion Injury in Rat Ovary.

Background/Aims: Ovarian torsion is a common cause of local ischemic damage, reduced follicular activity and infertility. Platelet-rich plasma (PRP) contains growth factors with demonstrated cytoprotective properties; so we evaluated PRP efficacy in a rat ischemia/reperfusion (I/R) model. Methods: Sixty adult female Sprague-Dawley albino rats were randomly assigned to 6 groups of 8 animals each: Sham, Ischemia, I/R, Sham + PRP, I + PRP and I/R + PRP; and the remaining 12 used to prepare PRP. Ischemia groups were subjected to bilateral adnexal torsion for 3 h, while I/R and I/R + PRP groups received subsequent detorsion for 3 h. Intraperitoneal PRP was administered 30 min prior to ischemia (Ischemia + PRP) or reperfusion (I/R + PRP). Results: Total oxidant status (TOS), oxidative stress index (OSI) and total ovarian histopathological scores were higher in Ischemia and I/R groups than in the Sham group (p < 0.05). PRP decreased mean TOS, OSI and histopathological scores in I + PRP and I/R + PRP groups compared to the corresponding Ischemia and I/R groups (p < 0.001). There was a strong correlation between total histopathological score and OSI (r = 0.877, p < 0.001). Peritoneal vascular endothelial growth factor was significantly higher in PRP-treated groups than corresponding untreated groups (p < 0.05). Conclusion: PRP is effective for the prevention of ischemia and reperfusion damage in rat ovary.

Plasma apelin levels in patients with polycystic ovary syndrome.

OBJECTIVE The aim of the study was to evaluate plasma apelin levels in patients with polycystic ovary syndrome (PCOS) and healthy controls. MATERIAL AND METHODS Plasma apelin levels, serum lipid levels, serum hormone levels, and homeostasis model assessment-insulin resistance (HOMA-IR) values of 32 patients with PCOS and 31 healthy women forming the control group were checked. RESULTS Plasma apelin levels of the PCOS group (0.350±0.083 ng/ml) were significantly higher than those of the control group (0.246±0.045 ng/ml) (p<0.001). No significant correlation was detected between apelin levels and biochemical or clinical data in PCOS group. CONCLUSION Plasma apelin levels were significantly higher in PCOS patients.

Utility of preoperative neutrophil-to-lymphocyte and platelet-to-lymphocyte ratios to distinguish malignant from benign ovarian masses

OBJECTIVE We aimed to investigate the utility of preoperative neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and lymphocyte count as biomarkers to distinguish malignant from benign ovarian masses. MATERIAL AND METHODS We retrospectively reviewed the histopathological results of 185 benign and 33 malignant cases following surgery for an initial diagnosis of adnexal mass and confirmed ovarian masses. Age, cancer antigen 125 (CA-125), white blood cell (WBC) count, hemoglobin (Hb), hematocrit (Hct), mean platelet volume (MPV), platelet distribution width (PDW), NLR, PLR, and lymphocyte counts were compared between groups. RESULTS The significant diagnostic factors to distinguish malignant from benign disease were age (35.5±22 vs. 62±13 years; p<0.001) and CA-125 levels (16.6±21 vs. 98±366 U/mL; p<0.001). No significant difference was observed in WBC count, Hct, Hb, platelet count, PDW, and MPV between groups. To distinguish malignant from benign masses, lymphocyte count (1.29±0.91 vs. 1.80±0.67×10(3) cells/μL, p<0.001), NLR (4.95±5.36 vs. 3.32±2.72, p=0.024), and PLR (203.41±107.84 vs. 160.75±70.84, p<0.001) were identified as markers. The cutoff values were lymphocyte count of >1500 cells/μL (p<0.001), NLR of 3.4732 (p=0.033), PLR of 161.13 (p<0.001), CA-125 of >40 U/mL (p<0.001), and age of >53 years (p<0.001); their respective sensitivity and specificity were 66.7% and 77.8% [area under the curve (AUC), 0.723±0.055], 68.8% and 54.1% (AUC, 0.624±0.058), 81.8% and 50.8% (AUC, 0.683±0.052), 78.8% and 77.8% (AUC, 0.797±0.057), and 81.8% and 82.2% (AUC, 0.888±0.025). Multiple logistic regression analysis revealed cutoff explanatory and accuracy values of 68.2% and 94.9%, respectively, for lymphocyte count, NLR, PLR, CA-125, and age as independent parameters to distinguish malignant from benign ovarian masses. CONCLUSION In combination with age and CA-125 levels, NLR, PLR, and lymphocyte count may be helpful to preoperatively distinguish malignant from benign ovarian masses.

The effect of maternal hemoglobin concentration on fetal birth weight according to trimesters

Abstract Objective: To investigate the relationship between fetal birth weight and maternal hemoglobin concentrations in different trimesters. Methods: This prospective cross-sectional study comprised 329 women, monitored and delivered between January 2013 and January 2014 in our clinic. Hemoglobin concentrations in all trimesters and all birth weights of the newborns were recorded. Comparisons and correlations were made of the maternal hemoglobin concentrations and birth weights in each trimester. Results: A positive correlation was determined between fetal weight and increased first trimester maternal hemoglobin concentration (p: 0.025). No correlation was found between fetal weights and second and third trimester hemoglobin concentrations (p = 0.287, p = 0.298, respectively). When the effect of independent factors on fetal weight was investigated, it was determined that birth week and first trimester hemoglobin levels were the factors of most influence. Conclusions: Low hemoglobin concentrations in the first trimester of gestation seem to be associated with low fetal birth weights. Anemia can directly cause poor in utero fetal growth due to inadequate oxygen flow to the placental tissue or it can be an indirect indicator of maternal nutrition deficiency. In both circumstances, this study reveals that treatment of anemia before and in the early stages of pregnancy is directly correlated with better fetal outcomes.

The effects of electromagnetic fields on the number of ovarian primordial follicles: An experimental study.

The aim of this study was to evaluate the effect of an electromagnetic field (EMF), generated close to the ovaries, on primordial follicles. A total of 16 rats were used in this study. The study group consisted of rats exposed to an EMF in the abdominal region for 15 min/d for 15 days. Both the study and control group were composed of eight rats. After the treatment period of 15 days, the ovaries of the rats were extracted, and sections of ovarian tissue were taken for histological evaluation. The independent samples t test was used to compare the two groups. In the study group, the means of the right and left ovarian follicle numbers were 34.00 ± 10.20 and 36.00 ± 10.53, respectively. The average total ovarian follicle number was 70.00 ± 19.03. In the control group, the means of the right and left ovarian follicle numbers were 78.50 ± 25.98 and 71.75 ± 29.66, respectively, and the average total ovarian follicle number was 150.25 ± 49.53. The comparisons of the means of the right and left ovarian follicle numbers and the means of the total ovarian follicle numbers between the study and control groups indicated that the study group had significantly fewer follicles (p < 0.001, p = 0.011, and p = 0.002, respectively). This study found a significant decrease in the number of ovarian follicles in rats exposed to an EMF. Further clinical studies are needed to reveal the effects of EMFs on ovarian reserve and infertility.

Management of hematometrocolpos due to dysfunctional uterine bleeding following progestin use: a case report

Hematometrocolpos is accumulation of blood in the vagina and uterine cavity due to intra-uterine hemorrhage. A 20-year-old female presented to our clinic with massive menorrhagia at menarche after progestin usage. Hematometrocolpos was detected by transabdominal ultrasonography. She was pale because of heavy bleeding for 5 days and hemoglobin level was measured as 5.1 g/dl. Initial treatment was blood transfusion and medical drug therapy. After resolution of the hematometrocolpos was shown by transabdominal ultrasound 2 days later, the patient, who was stable, was discharged without complication. Obstruction of the female genital outflow tract is rarely seen. Hematocolpos has been reported in elderly women following vaginal occlusion due to radiotherapy, vaginal fibroma and labial synechiae causing infection or inflammatory conditions. The case is presented here because of the successful management of hematometrocolpos due to massive dysfunctional uterine bleeding in a young virgin patient.

Collision Tumor: Dermoid Cysts and Mucinous Cystadenoma in the Same Ovary and a Review of the Literature

Collision tumor is defined as the coexistence of two adjacent, but histologically distinct tumors without histological admixture in the same tissue or organ. Collision tumors involving ovaries are extremely rare. The coexistence of a mucinous cystadenoma with a dermoid cyst is infrequently reported. However, the most common histological combination of collision tumor in the ovary is the coexistence of teratoma with mucinous tumors. If a dermoid cyst accompanies a multiseptated cyst and if the multiseptalcyst contains fatty foci, these two components may be associated. Recognizing the potential for the coexistence of these two neoplasms in the same ovary is essential to be able to make a correct diagnosis.

Investigation of the efficacy of transobturator tape (TOT) surgery in stress urinary incontinence

OBJECTIVE: To evaluate the safety and efficacy of transobturator vaginal tape (TOT) in the management women with stress urinary incontinence (SUI) and to analyze functional results and subjective cure rates at follow- up visits. METHODS: Eighty-three consecutive women with SUI underwent TOT procedure. Data related to operative time, pre- and post-operative complications were collected. Subjective cure was defined as the absence of any urine loss on physical activity. RESULTS: Mean age of the patients was 53.2 years, and 66.3% of the patients had pure SUI. The mean operative time was 24.96 min in cases of isolated SUI treatment. The mean hospital stay was 1.53±0.68 days. At a mean follow-up of 32.8 months, the median subjective cure rate was 68.7 percent. Bladder injury (8.4%) was the only short and long term complication of this procedure. CONCLUSION: TOT is a safe and effective procedure for SUI with a low rate of long- term complications. The short -term complication like bladder perforation may develop based on the experience of the surgeons or concomitant pelvic surgery.
