[Show abstract][Hide abstract] ABSTRACT: Oxytocin (OT), a neurohypophysial nonapeptide, plays dual role as a neurotransmitter/neuromodulator and a hormone. It has also well known protective properties against ischemia/reperfusion organ damage. This study investigated the effect of OT on experimentally induced ovarian torsion/de-torsion ischemia/reperfusion (I/R) injury in rats. Sprague-Dawley rats were assigned to five treatment groups (n = 7/group): Group 1, sham-operated; Group 2, torsion; Group 3, 80 IU/kg of OT administration 30 min prior to torsion; Group 4, torsion/de-torsion; and Group 5, torsion followed by 80 IU/kg of OT administration 30 min prior to de-torsion. OT administration significantly decreased the tissue malondialdehyde (MDA) levels in both the torsion and OT group (Group 3), and torsion/de-torsion OT group (Group 5) in comparison with the torsion-only group (Group 2) and torsion/de-torsion group (Group 4). Histopathological finding scores including follicular degeneration, edema, hemorrhage, vascular congestion, and infiltration by inflammatory cells were found to be significantly decreased in the torsion and OT group (Group 3), and torsion/de-torsion OT group (Group 5) when compared with the torsion-only group (Group 2) and torsion/de-torsion group (Group 4). In conclusion, these results, verified with histopathologic evaluation and biochemical assays, suggest a probable protective role for OT in ischemia and I/R injury in rat ovaries.
[Show abstract][Hide abstract] ABSTRACT: Objective
To evaluate whether oral contraceptive pill (OCP) therapy has any effects on ovarian stromal blood flow by using pulsed and color Doppler at the end of three months follow-up period of OCP-users and non-users with or without Polycystic ovary syndrome (PCOS).
200 patients were included in the study. The patients were designed into four groups as follows; Group1: PCOS patients that received OCP containing 30 mcg ethinyl estradiol (EE) plus 3 mg drospirenone for 3 months. (DRP) (n = 50); Group 2: PCOS patients that received no medication (n = 50); Group 3: Healthy controls that received OCP(EE plus DRP) (n = 50); Group 4: Healthy controls that received no medication (n = 50). Resistance index(RI) and pulsatility index(PI) of both ovarian arteries, hormonal, anthropometric and biochemical parameters were assessed before and after 3 months.
There was a significant increament in RI and PI of both ovarian arteries in healthy controls (Group3) and in women with PCOS(Group 1) who received OCP (p < 0.001). The increament rate in both Doppler parameters were significantly higher in women with PCOS(Group 1) than healthy controls (Group 3) (p < 0.001).Whereas RI and PI values of both ovaries remained unchanged in all untreated women with or without PCOS (Group 2 and Group 4).
OCP therapy reduced ovarian vascularization in both PCOS and healthy users after 3 months of therapy and this decrease is especially noticeable in women with PCOS.

[Show abstract][Hide abstract] ABSTRACT: To determine whether procalcitonin (ProCT) levels can be used to predict subclinical intra-amniotic infection by comparing maternal plasma levels in preterm premature rupture of membranes (PPROM) and premature rupture of membranes (PROM) at term with the levels in healthy pregnant women.
The mean plasma ProCT levels of 32 patients with PPROM, 35 patients with PROM at term, 24 healthy women at preterm gestation and 30 healthy women at term were compared. In the PPROM group, the presence or absence of histological chorioamnionitis and neonatal infection were used as a reference to analyze ProCT levels.
The mean ProCT level of patients in the PPROM group was significantly higher than those in the PROM group and healthy controls. Patients in the PPROM group diagnosed with histological chorioamnionitis had significantly higher ProCT levels than those of the remaining patients. At a cut-off of 0.054 ng/mL, the sensitivity and specificity of ProCT to predict histological chorioamnionitis were 92.3% and 68.4%, respectively.
ProCT levels were significantly higher in patients with PPROM, and facilitate identification of those who require expectant management.

[Show abstract][Hide abstract] ABSTRACT: PURPOSE: The present study was designed to examine apoptotic cell death via the caspase-dependent pathway in human fetal membranes. METHODS: Amniotic membrane samples were collected from three groups of women: group 1, women with preterm premature rupture of fetal membranes (PPROM) after cesarean delivery (n = 10), group 2, women with preterm labor (PTL) with intact membranes after cesarean delivery (n = 9) and group 3, women with term labor and vaginal delivery after an uncomplicated pregnancy (controls) (n = 11). RESULTS: Active caspase-3 immunopositivity (ACPI) of the PPROM group was significantly higher than that of the control group (p < 0.05). ACPI was higher in the PTL with intact membranes group as compared to the control group; however, it did not reach statistical significance (p > 0.05). CONCLUSION: Active caspase-3 positivity is increased in the fetal membranes of those women with PPROM.

[Show abstract][Hide abstract] ABSTRACT: To compare the peri- and postoperative complication rates of two cesarean delivery techniques.
Medical records from 1,087 patients who had a cesarean delivery with regional anesthesia between 2008 and 2010 were reviewed retrospectively. Seven hundred and thirty-two patients had an in situ uterine repair, and 355 patients had an exterior uterine repair. Patients who had chorioamnionitis, preeclampsia, a bleeding disorder, or abnormal placentation were excluded from the study. The following outcomes were compared between the two groups: mean operative time, intraoperative blood loss, perioperative nausea, tachycardia, hypotension, hemoglobin level, hematocrit level, the time to the first recognized bowel movement, postoperative analgesic dose, nausea, length of hospital stay, surgical site infection rate and endometritis rate.
No clinically significant differences were found between the exteriorization and in situ uterine repair groups for mean hematocrit differences, intraoperative blood loss, perioperative nausea, tachycardia, hypotension and postoperative analgesic doses. However, the mean operative time, time to the first recognized bowel movement, surgical site infection rate and length of hospital stay were significantly lower in the in situ repair group (p < 0.05).
Although the techniques are similar in most scenarios, in situ uterine repair during cesarean sections appears to be more advantageous than exteriorization with respect to the mean operative time, time to the first recognized bowel movement, surgical site infection rate and length of hospital stay.

[Show abstract][Hide abstract] ABSTRACT: Frozen section is an important diagnostic tool to determine the nature of the ovarian masses intraoperatively. The optimal surgical treatment can be achieved by classifying the masses as benign, borderline and malignant. The aim of this retrospective study was to evaluate the accuracy of frozen section diagnosis of ovarian neoplasms and to determine the effects of Gynecologic (Gyn) pathologist or non-Gyn pathologist on frozen section diagnosis.
Intraoperative frozen section diagnosis was retrospectively evaluated in 578 patients operated with the suspicion of ovarian neoplasms. We compared the results of frozen section diagnosis by Gyn pathologists (Group 1) and by non-Gyn (Group 2) pathologists.
In 23 patients (3.9%), the tissues were other than ovary. No opinion could be obtained on frozen sections of 14 cases (2.4%). The sensitivities for benign, borderline and malignant tumors for frozen section diagnoses of Gyn pathologists were 99.7%, 89.5%, and 96.3% respectively. The corresponding specificities were 97.6%, 85% and 99%, respectively. Group 2 pathologists had sensitivities and specificities of 97%, 50%, 84.6% and 95.2%, 96.2% and 94.5% for benign, borderline and malignant tumors, respectively. The overall accuracy rate of frozen section was 97.1%.
Intraoperative frozen section diagnosis has a high accuracy rate for ovarian pathologies. Those rates do increase even more if it is evaluated by the Gyn pathologists.
[Show abstract][Hide abstract] ABSTRACT: To evaluate the association between follicular fluid levels of propeptide and mature forms of growth differentiation factor (GDF) 9 and bone morphogenetic protein (BMP) 15 with subsequent oocyte and embryo quality.
Prospective clinical study.
Eighty-one infertile patients who underwent in vitro fertilization (IVF)/intracytoplasmic sperm injection (ICSI).
The expression levels of the propeptide and mature forms of follicular fluid GDF9 and BMP15 were determined by western blot analysis. The levels of follicular fluid hormones (FSH, E2, and P) were measured with automated chemiluminescent enzyme immunoassays.
The relationships between the levels of GDF9 and BMP15, hormones, oocyte maturation, and embryo quality.
Mature GDF9 levels were significantly correlated with the nuclear maturation of oocytes. The mean mature GDF9 level was 4.87±0.60 in the high-embryo-quality group and 1.45±0.81 in the low-embryo-quality group. There were no statistically significant differences in embryo quality among the patients regarding propeptide GDF9 and BMP15 expression status. There was a negative correlation between follicular fluid levels of P and the mature form of GDF9.
Higher mature GDF9 levels in the follicular fluid were significantly correlated with oocyte nuclear maturation and embryo quality.

[Show abstract][Hide abstract] ABSTRACT: We aimed to evaluate the alteration of cardiovascular and metabolic risk parameters of polycystic ovary syndrome (PCOS) patients after a 6-month treatment with an oral contraceptive (OC) containing cyproterone acetate (CPA).
Forty women with PCOS were evaluated at baseline and after treatment with an OC. Carotid intima-media thickness (CIMT), brachial artery flow-mediated dilatation (FMD), nitrate-mediated dilatation (NMD), high sensitive (hs)-CRP, lipid levels, index of glucose sensitivity, and homeostasis model assessment of insulin resistance index (HOMA) were assessed.
Mean CIMT was significantly elevated (0.03 ± 0.01 mm) (p < 0.05). There was a tendency of reduction in FMD, which was significant among overweight patients (p < 0.05). Total cholesterol, low-density lipid (LDL), and triglyceride levels were significantly elevated (p < 0.05).
CIMT as an indicator of early atherosclerosis and FMD as a finding of endothelial dysfunction seem to be deteriorated especially in overweight PCOS patients who were prescribed to OC containing cyproterone acetate for 6 months.
