PURPOSE: To evaluate the sonographic parameters related to morphological characteristics of pelvic adnexal masses by obtaining two-dimensional images by an observer presence, forwarded electronically (via tele-ultrasound) in static and dynamic modes observers do not face (distance) for comparative analyzes inter intraobserver and to the validation of a second opinion. METHODS: From March to August 2010 were selected 50 patients with adnexal mass viewing of the pelvic ultrasound. They were subjected to ultrasound for abdominal and transvaginal routes. The images were captured in static and dynamic modes, electronically forwarded for evaluation of non-presence and two examiners evaluated according to morphological ultrasonographic parameters previously determined. RESULTS: The evaluators did not face in static and dynamic modes obtained almost perfect agreement for all morphological parameters with Kappa values between 0.6 and 0.8. There was no difference between the methods employed, except for the morphological parameter papillary projection in the static mode , in which the agreement was almost perfect ( 0.8 ) while in dynamic mode was substantial (0.6). CONCLUSIONS: The sonographic parameters of the features of adnexal masses pelvic sent by tele-ultrasound are capable of being validated for issuing a second opinion. There were no significant differences in the methodology used in the issue of tele-ultrasound images (static or dynamic) to characterize the composition of pelvic adnexal masses.

PURPOSE: To analyze the time between the first symptom and treatment in patients treated for breast cancer in public hospitals in the Federal District. METHODS: This was a cross-sectional analysis. We interviewed 250 women diagnosed with breast cancer treated in six hospitals of the State Department of Health of the Federal District from November 2009 to January 2011. The time intervals studied were the time between the detection of the symptoms and treatment subdivided into intervals until and after the first medical appointment. The variables were: age, menopausal status, color, educational level, average monthly household income, origin, reason for the initial consultation, staging, tumor size, laterality, metastasis to axillary lymph nodes, neoadjuvant chemotherapy, and type of surgery. The Mann-Whtney test was used to assess the association of these variables with the time intervals until treatment. RESULTS: The mean age was 52 years, with a predominance of white women (57.6%), from the Federal District (62.4%), with a family income of up to 2 minimum wages (78%), and up to four years of schooling (52.4%). The staging of the disease ranged from II to IV in 78.8% of the women. The time between the first symptom and treatment was 229 days (median). After detection of the first symptom, 52.9% of the women attended a consultation within 30 days and 88.8% took more than 90 days to start treatment. Women with elementary school education had a greater delay to the start of treatment (p=0.049). CONCLUSIONS: There was a significant delay to start treatment of women with breast cancer in public hospitals of the Federal District, suggesting that efforts should be made to reduce the time needed to schedule medical appointments and to diagnose and treat these patients.

PURPOSE: To quantify the number of defense cells and immunoglobulin E (IgE) levels in peripheral blood sampled from women with recurrent vulvovaginal candidiasis. METHODS: A cross-sectional study was conducted on 60 women, 40 with vulvovaginal candidiasis and 20 controls. The defense cells were identified using an impedance system combined with flow cytometry and total and specific IgE was measured by chemiluminescence. The Mann-Whitney test was used for nominal variables and the Spearman test was used to determine the correlation of IgE concentration and eosinophils in peripheral blood. RESULTS: The number of eosinophils in peripheral blood from patients with recurrent vulvovaginal candidiasis, 302.60 (±253.07), was significantly higher compared to control, 175.75 (±109.24) (p=0.037). Serum levels of total and specific IgE were similar in the groups of women with and without recurrent vulvovaginal candidiasis (p=0.361). However, there was a moderate positive correlation between eosinophils and total serum IgE in the candidiasis group (r=0.25). CONCLUSION: Women with recurrent vulvovaginal candidiasis are more likely to have eosinophils in peripheral blood.

PURPOSE: To analyze prenatal care in public and private services. METHODS: A cross-sectional, retrospective and analytic study was conducted based on the audit of files of pregnant women who had given birth at a reference hospital for low risk cases in the area of Campos Gerais - Paraná State, in the first semester of 2011. The Yates chi-squared test or exact Fisher test were used to determine the association between the lack of registration files for pregnant women regarding prenatal assistance in the public and private services, with the level of significance set at p≤0.05. The quality of prenatal care was determined based on the percentile of non-registrations. RESULTS: A total of 500 prenatal files were analyzed. There was a significant attendance of six or more prenatal visits, with a larger proportion in the private service (91.9%). The laboratory and obstetric exams most frequently not registered in the public and in the private services were, respectively: hepatitis B (79.3 and 48.4%), hemoglobin and hematocrit values (35.6 and 21.8%), anti-HIV serology (29.3 and 12.9%), fetal movement (84.3 and 58.9%) and length (60.4 and 88.7%), edema verification (60.9 and 54.8%), and fetal presentation (52.4 and 61.3%). The audit of the files of pregnant women allowed to determine the quality of the prenatal care provided and confirmed differences in assistance according to the place, showing excellent and good quality of private care, and regular public care for ultrasonography and blood type/Rh factor; regular quality of private care and poor quality of public care for urine tests and weight. For the other types of laboratory and obstetric exams and vaccines, the quality was poor or very poor in both types of services. CONCLUSION: The differences between the services showed that there is a need for actions aiming at the improvement of the prenatal care provided by public services.

PURPOSE: To describe the prevalence of maternal mortality at a tertiary care hospital and to assessits preventability. METHODS: This study, through the analysis of maternal deaths that occurred during the period from 1999 to 2010 at a reference in Campinas - Brazil, CAISM/ UNICAMP, discusses some of the factors associated with the main causes of death and some structural problems of structure of the health services. It is a retrospective descriptive study with evaluation of sociodemographic variables and the medical and obstetric history of women, and the causes of death. RESULTS: The majority of maternal deaths occurred due to direct obstetric (45%) and avoidable (36%) causes, in women with preterm gestation, who delivered by cesarean section (56%) and received various management procedures, including blood transfusion, ICU admission and need for laparotomy and/or hysterectomy. The hospital transfer was associated with the predominance of direct obstetric (19 versus 6, p=0.02) and avoidable causes (22 versus 9, p=0.01). CONCLUSIONS: We conclude that, despite current advances in Obstetrics, infections and hypertensive disorders are still the predominant causes of maternal mortality. We observed an increase of clinical-surgical conditions and neoplasms as causes of death among women during pregnancy.

PURPOSE: To characterize and compare clinical, anthropometric and biochemical-metabolic variables in patients with polycystic ovary syndrome (PCOS), stratified according to body mass index (BMI). METHODS: A cross-sectional study conducted on 78 women aged 18 to 45 years with a clinical diagnosis of PCOS by the Rotterdam criteria. Patients were stratified according to BMI. The variables analyzed were: age, marital status, physical inactivity, menstrual irregularity, blood pressure (BP), anthropometric measurements, lipid profile, fasting glucose, and hormone measurements. To compare the variables between the different BMI values we used analysis of variance and the Kruskal-Wallis test. The level of significance was set at 5% for all tests. RESULTS: The patients had a mean age of 26.3 years, 79.5% of them were sedentary and 68% had hyperandrogenism. Waist circumference, waist/hip ratio, waist/height ratio and percentage of body fat were higher in the obese group. The markers of cardiovascular risk (CVR - fasting glucose, systolic and diastolic BP and LDL-cholesterol) were directly proportional to BMI, whereas HDL-cholesterol and SHBG were inversely related to BMI. CONCLUSION: The presence of markers of CVR factors increased proportionally to BMI, indicating that the metabolic profile of obese women with PCOS is more unfavorable than that of non-obese patients.

PURPOSE: To investigate the usefulness of the measurement of cervical length and of the test for phosphorylated insulin-like growth factor binding protein-1 (phIGFBP-1) performed sequentially in the prediction of preterm birth and the correlation between tests. METHODS: We analyzed data from 101 asymptomatic pregnant women with a history of premature delivery. The ultrasound measurement of cervical length and phIGFBP-1 test were performed in parallel every three weeks, between 24 and 34 week. The best cutoff value for each cervical evaluation was established by the ROC curve, and the two tests were compared using nonparametric tests. We determined the sensitivity, specificity and predictive values of each test and of the association of the exams for the occurrence of delivery before the 37th weeks. RESULTS: There were 25 preterm births (24.8%). The cervix length showed the highest sensitivity and was able to predict preterm birth in all evaluations, with similar accuracy at different gestational ages. The test for phIGFBP-1 was not helpful at 24 weeks, but was able to predict prematurity when performed at 27, 30 and 33 weeks. The combination of tests increased the sensitivity (81.8%) and negative predictive value (93.7%) when compared to the separate use of each test. The mean cervical length was lower in women with a positive test. CONCLUSIONS: Both cervical length and the test for phIGFBP-1 were able to predict premature delivery, and sequential combination of both tests showed a high sensitivity and high negative predictive value.

PURPOSE: It was to determine the prevalence of Chlamydia trachomatis and the risk factors associated with infection in endocervical specimens from women seen in outpatient Obstetrics and Gynecology. METHODS: Samples of endocervical secretion of 200 women treated at the University Hospital of the Federal University of Rio Grande were analyzed for the presence of C. trachomatis by polymerase chain reaction (PCR) using primers that amplify CT05/CT06 281 base pairs of the main outer membrane protein of C. trachomatis. All participants completed a pre-coded and self-report questionnaire. Data were analyzed with the SPSS 17.0 software; for multivariate analysis it was used Poisson regression. RESULTS: Of the 200 women who were included in the study, the prevalence of infection with C. trachomatis was 11% (22 patients) and these 55 (27.5%) were positive for HPV. Risk factors associated with infection by C. trachomatis were: 8 years or less of schooling (p<0.001), family income below the poverty level (p=0.005), first intercourse at age 15 or less (p=0.04) and being a carrier of the virus HIV (p<0.001). After multivariate analysis, only the variables of schooling or less than eight years (PR 6.0; 95%CI 1.26 - 29.0; p=0.02) and presence of HIV (RP 14.1; 95%CI 3.4 - 57.5; p<0.001) remained statistically significant. CONCLUSIONS: The prevalence of C. trachomatis in endocervical specimens by PCR was 11%. The factors associated with a higher infection by C. trachomatis were lower education and being HIV positive.
