To define transvaginal ultrasound reference ranges for uterine cervix measurements according to gestational age (GA) in low-risk pregnancies.
Cohort of low-risk pregnantwomen undergoing transvaginal ultrasound exams every 4 weeks, comprisingmeasurements of the cervical length and volume, the transverse and anteroposterior diameters of the cervix, and distance fromthe entrance of the uterine artery into the cervix until the internal os. The inter- and intraobserver variabilities were assessed with the linear correlation coefficient and the Student t-test. Within each period of GA, 2.5, 10, 50, 90 and 97.5 percentiles were estimated, and the variation by GA was assessed with analysis of variance for dependent samples. Mean values and Student t-test were used to compare the values stratified by control variables.
After confirming the high reproducibility of the method, 172 women followed in this cohort presented a reduction in cervical length, with an increase in volume and in the anteroposterior and transverse diameters during pregnancy. Smaller cervical lengths were associated with younger age, lower parity, and absence of previous cesarean section (C-section).
In the studied population, we observed cervical length shortening throughout pregnancy, suggesting a physiological reduction mainly in the vaginal portion of the cervix. In order to better predict pretermbirth, cervical insufficiency and premature rupture of membranes, reference curves and specific cut-off values need to be validated.

To assess the knowledge and compliance of health professionals regarding the diagnostic and treatment practices for syphilis in patients admitted for childbirth in public maternity hospitals in the city of Teresina, in the state of Piauí, Northeastern Brazil.
A cross-sectional study was performed in 2015 with obstetricians and nurses working in the public maternity hospitals in Teresina (n = 159) using a selfadministered questionnaire, with 5% of losses and 10% of refusals. The study used 21 evaluation criteria: 13 of them were related to knowledge (5 on serological tests and 8 on treatment adequacy); 8 were related to practices (3 on diagnosis, 4 on treatment, and 1 on post-test counseling). The knowledge of and compliance to the practices was estimated as the proportion of health professionals’ answers that were in agreement with Brazilian Ministry of Health protocols.
The obstetricians were in agreement with twocriteria concerning the knowledge of serological tests, one for diagnostic practices, and one for treatment practice. Among nurses, no single match between actual procedures and guidelines was observed.
Low compliance with the protocols results in missed opportunities for the diagnosis and treatment of pregnant and postpartum women and their partners. Strategies for training and integrating the various professional groups, improved data recording on prenatal cards, and greater accountability of the hospital team in managing the women’s partners are needed to overcome the barriers identified in the study and to interrupt the syphilis transmission chain.

To describe the blood flow velocities and impedance indices changes in the uterine arteries of leiomyomatous uteri using Doppler sonography.
This was a prospective, case-control study conducted on 140 premenopausal women with sonographic diagnosis of uterine leiomyoma and 140 premenopausal controls without leiomyomas. Pelvic sonography was performed to diagnose and characterize the leiomyomas. The hemodynamics of the ascending branches of both main uterine arteries was assessed by Doppler interrogation. Statistical analysis was performed mainly using non-parametric tests.
The median uterine volume of the subjects was 556 cm3, while that of the controls was 90.5 cm3 (p < 0.001). The mean peak systolic velocity (PSV), end-diastolic velocity (EDV), time-averaged maximum velocity (TAMX), time-averaged mean velocity (Tmean), acceleration time (AT), acceleration index (AI), diastolic/systolic ratio (DSR), diastolic average ratio (DAR), and inverse pulsatility index (PI) were significantly higher in the subjects (94.2 cm/s, 29.7 cm/s, 49.1 cm/s, 25.5 cm/s, 118 ms, 0.8, 0.3, 0.6, and 0.8 respectively) compared with the controls (54.2 cm/s, 7.7 cm/s, 20.0 cm/s, 10.0 cm/s, 92.0 ms, 0.6, 0.1, 0.4, and 0.4 respectively); p < 0.001 for all values. Conversely, the mean PI, resistivity index (RI), systolic/diastolic ratio (SDR) and impedance index (ImI) of the subjects (1.52, 0.70, 3.81, and 3.81 respectively) were significantly lower than those of the controls (2.38, 0.86, 7.23, and 7.24 respectively); p < 0.001 for all values.
There is a significantly increased perfusion of leiomyomatous uteri that is most likely due to uterine enlargement.

Using three-dimensional ultrasound (3D-US), we aimed to compare the tape position and the angle formed by the sling arms in different techniques of midurethral sling insertion for the surgical treatment of stress urinary incontinence, three years after surgery. In addition, we examined the correlations between the US findings and the clinical late postoperative results.
A prospective cross-sectional cohort study of 170 patients who underwent a sling procedure between May 2009 and December 2011 was performed. The final sample, with US images of sufficient quality, included 26 retropubic slings (tension-free vaginal tape, TVT), 42 transobturator slings (tension-free vaginal tape-obturator, TVTO), and 37 single-incision slings (tension-free vaginal tape-Secur, TVT-S). The images (at rest, during the Valsalva maneuver, and during pelvic floor contraction) were analyzed offline by 2 different observers blinded against the surgical and urinary continence status. Group comparisons were performed using the Student t-test, the chi-squared and the Kruskal-Wallis tests, and analyses of variance with Tukey multiple comparisons.
Differences among the groups were found in themean angle of the tape arms (TVT = 119.94°, TVT-O = 141.93°, TVT-S = 121.06°; p < 0.001) and in the distance between the bladder neck and the tape at rest (TVT = 1.65 cm, TVT-O = 1.93 cm, TVTS = 1.95 cm; p = 0.010). The global objective cure rate was of 87.8% (TVT = 88.5%, TVT-O = 90.5%, TVT-S = 83.8%; p = 0.701). The overall subjective cure rate was of 83.8% (TVT = 88.5%, TVT-O = 88.5% and TVT-S = 78.4%; p = 0.514). The slings were located in the mid-urethra in 85.7% of the patients (TVT = 100%, TVT-O = 73.8%, TVTS = 89.2%; p = 0.001), with a more distal location associated with obesity (distal: 66.7% obese; mid-urethra: 34% obese; p = 0.003). Urgency-related symptoms were observed in 23.8% of the patients (TVT = 30.8%, TVT-O = 21.4%, TVT-S = 21.6%; p = 0.630).
The angle formed by the arms of the sling tape was more obtuse for the transobturator slings compared with the angles for the retropubic or single-incision slings. Retropubic slings were more frequently located in the mid-urethra compared with the other slings, regardless of obesity. However, the analyzed sonographic measures did not correlate with the urinary symptoms three years after the surgery.

To evaluate the coverage of the Papanicolaou test in Brazil and the associated factors.
Cross-sectional study based on data from the Brazilian Health Survey 2013 comprising the proportion of 25- to 64-year-old women who had undergone a Papanicolaou test within the previous 3 years, categorized by sociodemographic variables and access to healthcare services.
The screening coverage in Brazil was of 79.4% (95% confidence interval [95%CI]: 78.4-80.3), showing significant differences between the different states of the country, with the highest rate in the state of Roraima (86.5; 95%CI: 83.5-89.4), and the lowestone in the state ofMaranhão (67.7; 95%CI: 61.3-74.0).Undergoing the test was significantlymore frequent amongmarriedwomen (83.6%; 95%CI: 82.4-84.8), those with higher educational levels (88.7%; 95%CI: 87.0-90.5), of white ethnicity (82.6%; 95%CI: 81.3-83.9) and who reside in urban areas (80.1%; 95%CI: 79.1-81.2). Those who had undergone the test more than three years prior to the survey and the ones who had never undergone it were associated with a lower level of education, being of black or brown ethnicity, single or divorced, and rural dwellers.
The coverage of cervical cancer screening in Brazil is below the recommended rate and presents regional and sociodemographic disparities.

To evaluate the preferences of women and men regarding female pubic hair depilation and identify possible reasons for these preferences.
This is a cross-sectional study of men and women over 18 years old who were invited by the official blog of our institution to respond anonymously to an online and self-administered questionnairemade by the researchers. The analyses weremade using the Statistical Analysis System (SAS, SAS Inc., Cary, NC, US) software, version 9.3, and contingency tables were used to verify the distribution of variables. The univariate statistical analysis was performed using the Pearson chi-squared test, and the differences for values of p < 0.05 were considered significant.
We obtained data from 69,920 subjects (52,787 women and 17,133 men). Themean age was 31.9 years formen, and 28.5 years for women. Most women (64.3%) and men (62.2%) preferred complete removal of female pubic hair, and this preference wasmore pronounced in younger women andmen. Most women reported performing depilation at home (55.8%), with 44.4% using hot wax and 40.1% using a razor blade. About half of the women (44.7%) and men (50.1%) reported sexual activity, having intercourse 2 to 3 times per week. The frequency of intercourse and sexual satisfaction in women correlated with total pubic hair removal.
Most Brazilian women and men prefer the complete removal of female pubic hair, especially those who are younger andmore sexually active.Women who are satisfied with the appearance of their own genitalia have a stronger preference for complete removal of pubic hair.

The authors review hypertensive disease during pregnancy with an academic and practical view, and using the best evidence available. This disease, which is the most important clinical disease in Brazilian pregnant women, may have its incidence reduced with prevention through the use of calcium and aspirin in pregnant women at risk. Previously, it was a disease that presented with hypertension with proteinuria, but it has now been classified with new clinical parameters besides proteinuria. Morbidity and mortality should be reduced in a continental country such as Brazil using protocols for the early treatment of complications by calculating severe outcomes in preeclampsia. The early treatment of acute hypertension, use of magnesium sulfate and early hospitalization in cases of preeclampsia are concepts to pursue the reduction of our pregnant women’s mortality.
