To evaluate the precision of both two- and three-dimensional ultrasonography in determining vertebral lesion level (the first open vertebra) in patients with spina bifida.
This was a prospective longitudinal study comprising of fetuses with open spina bifida who were treated in the fetal medicine division of the department of obstetrics of Hospital das Clínicas of the Universidade de São Paulo between 2004 and 2013. Vertebral lesion level was established by using both two- and three-dimensional ultrasonography in 50 fetuses (two examiners in each method). The lesion level in the neonatal period was established by radiological assessment of the spine. All pregnancies were followed in our hospital prenatally, and delivery was scheduled to allow immediate postnatal surgical correction.
Two-dimensional sonography precisely estimated the spina bifida level in 53% of the cases. The estimate error was within one vertebra in 80% of the cases, in up to two vertebrae in 89%, and in up to three vertebrae in 100%, showing a good interobserver agreement. Three-dimensional ultrasonography precisely estimated the lesion level in 50% of the cases. The estimate error was within one vertebra in 82% of the cases, in up to two vertebrae in 90%, and in up to three vertebrae in 100%, also showing good interobserver agreement. Whenever an estimate error was observed, both two- and three-dimensional ultrasonography scans tended to underestimate the true lesion level (55.3% and 62% of the cases, respectively).
No relevant difference in diagnostic performance was observed between the two- and three-dimensional ultrasonography. The use of three-dimensional ultrasonography showed no additional benefit in diagnosing the lesion level in the fetuses with spina bifida. Errors in both methods showed a tendency to underestimate lesion level.

The purpose of this study is to verify the use ofmedicinal plants by pregnant women treated at four Basic Health Units and at a public maternity facility in Brazil s northeast.
This is a cross-sectional, quantitative study, performed between February and April 2014. The subjects were 178 pregnant women, aged 18 to 42 years. To collect data, a structured questionnaire with dichotomous and multiple choice questions was used. To verify the correlation between the variables, Pearson s chi-square test was used.
The study showed that 30.9% of the pregnant women used medicinal plants, and boldo was the most cited (35.4%). All the plants utilized, except lemongrass, have toxic effects in pregnancy, according to Resolution SES/RJ N° 1757. There was no statistically significant correlation between social class and use of medicinal plants.
The health of the study participants and their unborn children is at risk due to the inappropriate use of medicinal plants.

To evaluate the compliance and degree of satisfaction of nulligravida (has not given birth) and parous (had already given birth) women who are using intrauterine devices (IUDs).
A cross-sectional cohort study was conducted comparing nulligravida and parous women who had had an IUD inserted between July 2009 and November 2011. A total of 84 nulligravida women and 73 parous women were included. Interviews were conducted with women who agreed to participate through telephone contact. Statistical analysis was performed with Student s t-test and Mann-Whitney test for numeric variables; Pearson s chi-square test to test associations; and, whenever pertinent, Fisher s exact test for categorical variables. A survival curve was constructed to estimate the likelihood of each woman continuing the use of the IUD. A significance level of 5% was established.
When compared with parous women, nulligravida women had a higher education level (median: 12 vs. 10 years). No statistically significant differences were found between the nulligravida and parous women with respect to information on the use of the IUD, prior use of other contraceptive methods, the reason for having chosen the IUD as the current contraceptive method, reasons for discontinuing the use and adverse effects, compliance, and degree of satisfaction. The two groups did not show any difference in terms of continued use of the IUD (p = 0.4).
There was no difference in compliance or the degree of satisfaction or continued use of IUDs between nulligravida and parous women, suggesting that IUD use may be recommended for women who have never been pregnant.

The aim of this study was to study the effects of Tribulus terrestris on sexual function in menopausal women.
This was a prospective, randomized, double-blind, placebo-controlled clinical trial that included 60 postmenopausal women with sexual dysfunction. The women were divided into two groups, placebo group and Tribulus group, and evaluated by using the Sexual Quotient-female version (SQ-F) and Female Intervention Efficacy Index (FIEI) questionnaires.
There was no significant difference between the groups in age, age at menopause, civil status, race, and religion. In the evaluation with the SQ-F questionnaire, there were significant differences between the placebo (7.6±3.2) and Tribulus (10.2±3.2) groups in the domains of desire and sexual interest (p d" 0.001), foreplay (3.3±1.5 versus 4.2±1.0) (p d" 0.01), arousal and harmonious interaction with the partner (5.7±2.1 versus 7.2±2.6) (p d" 0.01), and comfort in sexual intercourse (6.5±2.4 versus 8.0±1.9) (p d" 0.01). There was no significant difference between the placebo and Tribulus groups in the domains of orgasm and sexual satisfaction (p = 0.28). In the FIEI questionnaire, there was a significant improvement (p < 0.001) in the domains of vaginal lubrication during coitus and/or foreplay (20 versus 83.3%), sensation in the genitalia during sexual intercourse or other stimuli (16.7 versus 76.7%), sensation in the genital region (20 versus 70%), sexual intercourse and/or other sexual stimulations (13.3 versus 43.3%), and the ability to reach orgasm (20% versus 73.3%). There was no significant difference in adverse effects between the two groups.
After 90 days of treatment, at the doses used, we found Tribulus terrestris to be effective in treating sexual problems among menopausal women.

To compare the predictive capability of HPV and Pap smear tests for screening pre-cancerous lesions of the cervix over a three-year follow-up, in a population of users of the Brazilian National Health System (SUS).
This is a retrospective cohort study of 2,032 women with satisfactory results for Pap smear and HPV tests using second-generation hybrid capture,made in a previous study. We followed them for 36 months with data obtained from medical records, the Cervix Cancer Information System (SISCOLO), and the Mortality Information System (SIM). The outcome was a histological diagnosis of cervical intraepithelial neoplasia grade 2 or more advanced lesions (CIN2ş). We constructed progression curves of the baseline test results for the period, using the Kaplan-Meier method, and estimated sensitivity, specificity, positive and negative predictive value, and positive and negative likelihood ratios for each test.
A total of 1,440 women had at least one test during follow-up. Progression curves of the baseline test results indicated differences in capability to detect CIN2ş (p < 0.001) with significantly greater capability when both tests were abnormal, followed by only a positive HPV test. The HPV test was more sensitive than the Pap smear (88.7% and 73.6%, respectively; p < 0.05) and had a better negative likelihood ratio (0.13 and 0.30, respectively). Specificity and positive likelihood ratio of the tests were similar.
These findings corroborate the importance of HPV test as a primary cervical cancer screening.

To correlate the expression of high-risk HPV E6 mRNA with pap smear, colposcopy, and biopsy results in women with high grade squamous intraepithelial lesion (HSIL).
A cross-sectional study was performed on women referred for primary care services after cytological diagnosis of HSIL. We evaluated the expression of E6/E7 mRNA of HPV types 16,18,31,33, and 45 and correlated the results with those of Pap smear, colposcopy, and biopsy. For amplification/detection of mRNA E6 / E7 we used NucliSENSEasyQ kit to detect HPV mRNA by polymerase chain reaction with primers/ probes for HPV types 16, 18, 31, 33, and 45.
Out of 128 valid tests, the results of 30 (23.4%) tests were negative and 98 (70%) tests were positive. Only one type of HPV was detected in 87.7% of the E6/E7 mRNA positive cases. HPV16 was detected in 61.2% of the cases, followed by HPV33 (26.5%), HPV31 (17.3%), HPV18 (10%), and HPV45 (4.08%). Pap smear tests revealed that the E6/E7 test was positive in 107 (83.8%) women with atypical squamous cells - high grade (ASC-H), HSIL, or higher. The E6/E7 test was positive in 69 (57.5%) specimens presenting negative cytology results. When analyzing the association with colposcopy results, the frequency of positive E6/E7 results increased with the severity of the injury, ranging from 57.1% in women without colposcopy-detected injury to 86.5% in those with higher levels of colposcopy findings. Of the 111 women who underwent biopsy and E6/E7 testing, the E6/E7 test was positive in 84.7% of the women who presented with lesions of cervical intraepithelial neoplasia (CIN) grade 2 or higher. Finally, 41.2% of women with a negative biopsy presented a positive E6/E7 test.
E6/E7mRNA expression was higher in women with HSIL and CIN grade 2 or higher.
