Diagnostic accuracy of pre-induction cervical elastography, volume, length, and uterocervical angle for the prediction of successful induction of labor with dinoprostone.

PURPOSE: The study's aim is to define among a group of ultrasonographic cervical measurements a candidate parameter predictive of successful of induction of labor in term pregnancies with unfavorable cervix. METHODS: This prospective observational study included 141 pregnant women at term with an unfavorable cervix (Bishop score ≤ 6). All patients underwent clinical and ultrasonographic cervical evaluation before dinoprostone induction. Pre-induction cervical assessments included the Bishop score, cervical length, cervical volume, uterocervical angle, and cervical elastographic parameters. Vaginal delivery (VD) was accepted as successful dinoprostone induction. Multivariate logistic regression was conducted to identify the potential risk factors significantly associated with CS while controlling for possible confounding variables. RESULTS: The vaginal delivery rate was 74% (n = 93) and the cesarean section (CS) rate was 26% (n = 32). Sixteen patients who had a cesarean section due to fetal distress before the active phase of labor were excluded from the study. The mean induction-to-delivery interval was 1176.1 ± 352 (540-2150) for VD and 1359.4 ± 318.4 (780-2020) for CS (p = 0.01). Bishop score was lower in women with cesarean section (p = 0.002). When both groups were compared in terms of delivery type, no difference was found between cervical elastography values, cervical volume, cervical length, and uterocervical angle measurements. Multivariable logistic regression model failed to show significant differences between cervical elastography values, cervical volume, cervical length, and uterocervical angle measurements. CONCLUSION: Cervical length, cervical elastography, cervical volume, and uterocervical angle measurements did not provide a clinically useful prediction of outcomes following labor induction in our study group with unfavorable cervix. Cervical length measurements significantly predicted the time interval from induction to delivery.

Endocan is a predictor of increased cardiovascular risk in women with polycystic ovary syndrome.

PURPOSE: Endocan is a proteoglycan secreted mainly from endothelial cells. It has been implicated that there is a link between endocan and endothelial dysfunction. Polycystic ovary syndrome (PCOS) is a reproductive and metabolic disease associated with increased risk of cardiovascular events. The aims of this study were to ascertain whether circulating endocan levels are altered in women with PCOS, and whether there is an association between endocan and carotid intima media thickness (cIMT). MATERIALS AND METHODS: This cross-sectional study included 80 women with PCOS and 80 age- and BMI-matched controls without PCOS. Circulating endocan levels were measured using ELISA. Metabolic, hormonal parameters and cIMT were determined. 2-h oral glucose tolerance test (2-h OGTT) was performed on all women. RESULTS: Circulating endocan levels were significantly elevated in women with PCOS compared with controls (5.99 ± 2.37 vs. 3.66 ± 1.79 ng/ml, P < 0.001). Endocan levels positively correlated with BMI, homeostasis model assessment of insulin resistance (HOMA-IR), free androgen index (FAI), high-sensitivity C-reactive protein (hs-CRP), and cIMT in both PCOS and control groups. Endocan levels did not correlate with fasting blood glucose, 2-h OGTT, A1C and lipid parameters. Multiple linear regression analysis revealed that endocan is an independent predictor for cIMT (ß = 0.128, 95% CI = 0.118-0.138, P = 0.011). CONCLUSIONS: Circulating endocan levels are significantly higher in women with PCOS and endocan is independently associated with cIMT. Elevated endocan levels can be a predictor of increased cardiovascular risk in PCOS subjects.

Residual and recurrent disease rates following LEEP treatment in high-grade cervical intraepithelial lesions.

INTRODUCTION: Loop electrosurgical excision procedure (LEEP) is a basic procedure in the conization performed on patients with CIN II/III. After excisional therapy, close follow up is essential for the earlier detection of residual and recurrent disease. The value of PAP-smear and HPV-DNA tests for investigation of residual and recurrent disease in patients diagnosed with high-grade intraepithelial lesion after LEEP treatment was purposed. MATERIALS AND METHODS: 42 patients were included in the study for whom epithelial cell anomalies were detected at PAP-smear screening. HPV-DNA test, colposcopy, cervical biopsy and endocervical curettage and then LEEP procedures were performed. The patients were followed with HPV DNA and PAP-smear tests in terms of recurrence and residual disease at 3-month intervals. RESULTS: HPV-DNA examination revealed that 36 patients (85.7%) were positive for high-risk HPV-DNA before treatment. Histopathological evaluation of LEEP materials revealed the presence of CIN I in 4 and CIN II/III in 38 patients. Surgical margin was positive in five patients. No sign of invasive cervical neoplasia was detected. The high-risk HPV DNA's persistence was observed in 11 (30.6%) of the 36 patients of whom HPV-DNA positivity had been detected before the treatment. HSIL was detected in four patients using PAP-smear on the third month examination. Positive LEEP surgical margins were found to be positively correlated both with HPV-DNA positivity detected during the follow-up examination and with the presence of residual disease in the follow-up PAP smear. CONCLUSION: LEEP is a basic procedure in the conization performed on patients with CIN II/III. In spite of high recurrence and residual disease rates, this kind of patients requires close monitoring. Follow-up with HPV and PAP-smear tests after LEEP treatment is of great importance in the detection of residual or recurrent disease.

Association of kallistatin with carotid intima-media thickness in women with polycystic ovary syndrome.

BACKGROUND: Kallistatin is a secreted protein that acts as a tissue kallikrein inhibitor. It has anti-inflammatory, antioxidant and vasoprotective properties. Polycystic ovary syndrome (PCOS) is a reproductive and metabolic disease associated with low-grade chronic inflammation and multiple risk factors for cardiovascular diseases. The aims of this study were to ascertain whether circulating kallistatin levels are altered in women with PCOS, and whether there is an association between kallistatin and carotid intima-media thickness (cIMT) as well as inflammatory markers high-sensitivity C-reactive protein (hs-CRP) and tumor necrosis factor-α (TNF-α). METHODS: This cross-sectional study included 75 women with PCOS and 75 age- and BMI-matched controls without PCOS. Circulating kallistatin and TNF-α levels were measured using ELISA. Metabolic and hormonal parameters, hs-CRP levels and cIMT were also determined. All subjects underwent the 2-hour oral glucose tolerance test (2-h OGTT). RESULTS: Circulating kallistatin levels were significantly elevated in women with PCOS compared to controls (6.31±2.09 vs. 4.79±2.26 ng/mL, P<0.001). Inflammatory markers hs-CRP and TNF-α were found to be elevated in women with PCOS. Kallistatin levels positively correlated with insulin, insulin resistance index (HOMA-IR), free androgen index, hs-CRP, TNF-α and cIMT in both PCOS and control groups. Kallistatin levels did not show correlation with BMI, blood pressure, fasting blood glucose, 2-h OGTT or HbA1c. Multiple linear regression analysis revealed that kallistatin is an independent predictor for cIMT (ß=0.131, 95% CI: 0.114-0.150, P=0.019). CONCLUSIONS: Kallistatin levels may provide useful information regarding cardiovascular risk in women with PCOS.

Differences in Poly(ADP-ribose) Polymerase1- (PARP1-) and Proliferative Cell Nuclear Antigen (PCNA) Immunoreactivity in Patients Who Experienced Successful and Unsuccessful Microdissection Testicular Sperm Extraction Procedures.

PURPOSE: The aim of this study is to evaluate expression of deoxyribonucleic acid (DNA) synthesis and repair markers in testicular tissues of azoospermic men in whom sperm retrieval could and could not be achieved as a result of microdissection testicular sperm extraction (micro-TESE) procedure. MATERIALS AND METHODS: In this prospective cohort study, testicular tissues were retrieved from 60 Non-obstructive Azoospermia (NOA) patients who underwent micro-TESE procedure. These patients were divided into twogroups: micro-TESE positive group, which included 30 NOA patients from whom sperm could be extracted via micro-TESE procedure; and micro-TESE negative group, which included 30 NOA patients from whom sperm retrieval could not be achieved via micro-TESE procedure. Expression and distribution patterns of poly(ADP-ribose) polymerase-1 (PARP-1) and proliferative cell nuclear antigen (PCNA) in extracted tissues were assessedby immunohistochemical staining to reveal any differences in DNA synthesis and repair between the two groups. RESULTS: Micro-TESE positive group exhibited significantly stronger immunoreactivity for both PCNA and PARP-1 (P = .001 and P = .001 respectively). The results of this study reveal that both DNA synthesis and repair markers were expressed strongly in patients who experienced successful micro-TESE procedure. CONCLUSION: Although further studies are needed to support these findings, PARP-1 and PCNA expression in testicular tissues of NOA patients could be promising predictive factors for micro-TESE procedure success.

The positivity of Helicobacter pylori Stool Antigen in patients with Hyperemesis gravidarum.

OBJECTIVE: We aimed to investigate the possible association between Helicobacter pylori infection and Hyperemesis gravidarum. MATERIAL AND METHODS: Thirty-six pregnant women with Hyperemesis gravidarum with severe vomiting (more than 4 times a day), weight loss (≥3 kg), ketonuria and 36 pregnant women gestational age-matched, without nausea and vomiting attending our outpatient clinic for antenatal care were enrolled the study. Demographic data of the patients were registered. Blood samples for hemogram, serum electrolytes (sodium, potassium, chloride, and calcium), alanine aminotransferase (ALT), aspartate aminotransferase (AST), blood urea nitrogen (BUN), creatine, thyroid stimulating hormone (TSH), free T3-T4, total T3-T4, and urine samples for ketonuria, stool samples for HpSA were studied. The data of both groups were compared. RESULTS: Eight Hyperemesis gravidarum patients (22.2%) and 1 control patient (2.8%) were established HpSA positive and it was statistically significant (p:0.037). There was no significant difference between Hyperemesis gravidarum and control subjects in terms of age, gestational week, parity, educational level, socioeconomic status and smoking. There was anemia in 5 Hyperemesis gravidarum patients, 4 of them were HpSA positive. HpSA positivity was more prevalent in Hyperemesis gravidarum patients with anemia (p=0.003). Severe vomiting (more than 4 times a day), heartburn, epigastric pain, duration of hospitalization (more than 4 days) and weight loss (≥5 kg) were not correlated to HpSA positivity. CONCLUSION: The pregnant women with Hyperemesis gravidarum have a significantly higher prevalence of Helicobacter pylori compared with control subjects.
