RESUMO

In this case-control study, we aimed to evaluate the serum and seminal plasma levels of Selenium (Se), total antioxidant capacity (TAC), and Coenzyme Q10 (CoQ-10) and determine their relationship with sperm concentration, motility, and morphology in men with idiopathic infertility. A total of 59 subjects were enrolled in the study. Forty four patients were diagnosed with idiopathic male infertility and had abnormal sperm parameters, and 15 subjects had normal sperm parameters with proven fertility. Serum Se, semen Se, and semen TAC levels were significantly different in the fertile and infertile groups (p<0.01, p<0.001, and p<0.001, respectively). However, serum TAC, serum, and seminal plasma CoQ-10 levels did not differ between fertile and infertile groups. When the levels of the measured parameters were compared in serum and seminal plasma, serum levels of Se were found to be correlated positively with the semen levels in all subjects included into the study (N=59) (r=0.46, p<0.01). A relationship was found between neither serum and semen levels of TAC nor between serum and semen levels of CoQ-10. Correlations among measured serum and semen parameters with sperm parameters demonstrated that both the serum and semen levels of Se were correlated positively with spermatozoa concentration, motility, and morphology. Additionally, seminal plasma levels of TAC correlated positively with all these sperm parameters. On the other hand, seminal plasma levels of CoQ-10 correlated only with sperm morphology but not with concentration or motility. No relationship was observed between serum levels of TAC or serum levels of CoQ-10 and sperm parameters. In conclusion, serum and seminal plasma Se deficiency may be a prominent determinant of abnormal sperm parameters and idiopathic male infertility. Measurement of serum Se levels may help determine nutritional status and antioxidant capacity in infertile patients, which may help distinguish those patients who will benefit from supplementation therapy.

RESUMO

AIMS: The purpose of this study was to investigate correlations between first trimester placental volume (PV) and blood flow indexes (FIs), bilateral uterine artery pulsatility indexes, notching, and biochemical parameters: pregnancy-associated plasma protein-A (PAPP-A), free beta-human chorionic gonadotropin (f-ß-hCG), and insulin-like growth factor-1 (IGF-1) to predict the high-risk pregnancies in the first trimester. METHODS: We prospectively examined 310 patients at 11-14 weeks of pregnancy using transabdominal 3D gray scale and power Doppler ultrasound for assessing PV, vascularization index, FI, and vascularization FI (VFI). The acquired volumes were analyzed using VOCAL™ imaging software. The results were correlated with biochemical parameters. RESULTS: We found significant correlations between PV and biochemical parameters, and between placental blood flow studies and other parameters. Finally, PV/crown-rump length so called the placental quotient is also related to both PAPP-A and VFI. CONCLUSIONS: Placental volumetry, uterine artery Doppler studies, blood flow calculations and biochemical parameters, such as f-ß-hCG, PAPP-A, and IGF-1 could be important in the early and rapid diagnosis of high-risk pregnancies. Thus, they may be useful in first trimester prediction of fetal growth restriction presenting with alterations in PV and vascularity.

RESUMO

OBJECTIVE: To assess longitudinally the changes in cervical volume and vascularization during the peripartum period using three-dimensional ultrasound (3D US) and power Doppler and to determine whether these measures change with gestational complications. METHODS: Longitudinal measurements of cervical dimensions by transvaginal 3D US and power Doppler using the virtual organ computer-aided analysis program were performed at 11-14, 22-24, 32-34 weeks' gestation, and at 6 weeks' postpartum in 111 pregnant women. Comparisons were made between women who delivered at term (vs. preterm), nulliparous (vs. parous), with (vs. without) pre-eclampsia and those with (vs. without) gestational diabetes. RESULTS: After establishing reference values for each peripartum period for cervical volume, vascularization index (VI) and flow index (FI), we found that the 2(nd) and 3(rd) trimester volume, 2(nd) trimester FI and postpartum VI were different in nulli- vs. multiparous women. Volume and vascularization parameters were unaffected by preterm labor. Second trimester VI and vascularization flow index values were lower in pre-eclamptic vs. non-pre-eclamptic women (P<0.05), but unaffected by gestational diabetes. CONCLUSION: Cervical volume and vascularization parameters are not helpful in predicting preterm labor and gestational diabetes, but might be associated with pre-eclampsia.

RESUMO

PURPOSE: To determine the effectiveness and potential side effects of oral, vaginal, and sublingual intake of misoprostol on cervical dilatation prior to fractional curettage in patients with postmenopausal bleeding. METHODS: Seventy-six patients with postmenopausal bleeding during a period of 18 months were included in this randomized controlled trial. Patients were given 400 microg of misoprostol through the vaginal, oral, and sublingual routes, 12 h prior to the fractional curettage procedure. The degree of cervical dilatation, duration of the procedure, the side effects and complications were noted. RESULTS: When compared with the control group, misoprostol administered orally or sublingually was found to have a significant effect on cervical dilatation (P < 0.05). Of the three groups, nausea was found to be more common in the orally administered misoprostol group. CONCLUSIONS: We conclude that the oral or sublingual application of misoprostol prior to fractional curettage in patients with postmenopausal bleeding decreases the need for cervical dilatation.

RESUMO

Uterine rupture is one of the most feared obstetric complications, carrying an increased risk of maternal and perinatal morbidity and mortality. Here, we present a case of spontaneous uterine rupture during the first half of pregnancy. The patient did not report any recent trauma, however she had a history of laparoscopic myomectomy conducted three years earlier. The uterine rupture was 6-7 cm in length, located at the fundal level and was thought to originate from the previous myomectomy scar. In this report, we discuss the importance of choosing the right surgical technique and suturing method in patients undergoing myomectomy who desire to conceive in the future, and how obscure the findings of uterine rupture during pregnancy can be.

RESUMO

OBJECTIVES: To study the association between thickness of the umbilical cord at 11+0 to 14+6 gestational weeks and perinatal outcome. METHODS: We studied 216 pregnant women between 11+0 and 14+6 weeks' gestation with singletons, intact membranes, normal volumes of amniotic fluid and a regular menstrual period. Patients with umbilical cord measurements below the 5(th) centile were defined as thin umbilical cord group and those between the 5(th) and 95(th) or above 95(th) centile were defined as non-lean umbilical cord group. Abortion or fetal demise, preeclampsia, mode of delivery, gestational age at delivery, birth weight, and 5-min Apgar scores were noted. RESULTS: A statistically significant difference existed between the mean gestational age, mode of delivery, birth weight and adverse perinatal outcome of the two groups. The relative risk of the adverse perinatal outcome in lean umbilical cords was 6.92 (2.71-17.67; 95% CI). The umbilical cord thickness correlated with birth weight (P<0.05). CONCLUSIONS: Sonographic finding of a lean umbilical cord at 11+0 to 14+6 weeks' gestation should prompt the physician to strict monitoring of pregnancy.
