PURPOSE: to describe lower urinary tract dysfunctions and clinical demographic characteristics of patients with urinary symptoms. This study assessed the prevalence of diabetes mellitus and urodynamic changes in these women. METHODS: We conducted a cross-sectional, retrospective study on 578 women. The prevalence of diabetes mellitus and urodynamic diagnoses was assessed in patients with lower urinary tract dysfunctions, with their respective 95% confidence intervals. The prevalence ratios of urodynamic alterations were calculated according to the diabetes mellitus diagnoses. RESULTS: Seventy-seven patients (13.3%) had diabetes and type 2 diabetes was predominant (96.1%). Stress urinary incontinence was the most frequent urodynamic diagnosis (39%) in diabetic patients, followed by detrusor overactivity (23.4%). The prevalence of urodynamic alterations was associated with diabetes (PR=1.31; 95%CI=1.17-1.48). Changes in detrusor contractility (over- or underactivity) were diagnosed in 42.8% diabetic patients and in 31.5% non-diabetic patients. CONCLUSIONS: Diabetic women had a greater prevalence of urodynamic alterations than the non-diabetic ones. There was no association between diabetes mellitus and detrusor contractility alterations (p=0.80).

PURPOSE: To evaluate the influence of physical activity on the quality of life of middle-aged women. METHODS: A population-based cross-sectional study was conducted on 370 women aged 40 to 65 years-old recruited from a population-based sample. Enrollment took place in Basic Health Units in each health district of the city (North, South, East, and West) from June to September 2011. According to the Municipal Health Department of the City, 20,801 women were assisted at the Basic Health Units during a one-year period. The sample size calculation was stratified by district and based on a 95% confidence level with a power of 80%, as well as an error estimate of 5% and it was considered proportional to the number of patients classified as having adequate quality of life (indicator >26) in the general population. Data were collected while women waited for their routine appointment at the Health Unit. WHOQOL-Bref was used to evaluate the quality of life, and menopause rating scale (MRS) was used to determine climacteric symptoms. The level of physical activity was assessed by means of the International Physical Activity Questionnaire (IPAQ). To obtain the classification of PA levels, we used three categories: sedentary, moderately active, and very active. Statistical analysis was performed using the Minitab software, version 16. RESULTS: The mean age of the subjects was 49.8 years-old (±8.1) and they were predominantly Caucasian (72.7%), married (61.6%), non-smokers (93.5%), and had High School education (47.8%). Using the WHOQOL, mean scores were found to be significantly different between the groups (low, moderate, and vigorous physical activity), classified according to the domains of quality of life (p<0.01). Concerning physical activity and climacteric symptoms, significant differences were found for all domains: psychological (p<0.01), vegetative-somatic (p<0.01), and urogenital (p<0.01). CONCLUSIONS: Physical activity improves quality of life in middle-aged women.

PURPOSE: to compare three methods for the detection of HPV infection and to determine the prevalence of the genotypes found. METHODS: a total of 120 cervical scrape samples from patients with cervical intraepithelial neoplasia were analyzed by the conventional polymerase chain reaction using the MY09/11 and GP05+/06+ primers, and by the Nested polymerase chain reaction. The samples were subjected to DNA amplification with the GH20 and PC04 primers (β-globin) to verify DNA quality and also by polymerase chain reaction and Nested polymerase chain reaction. The amplicons were visualized in 1.2% agarose gel stained with Blue Green Loading Dye I. Positive samples also were sequenced using the automatic DNA sequencer "MegaBACE 1000". The Χ2 and Fisher tests were used for statistical analysis with the level of significance set at 5%. RESULTS: fifteen samples were eliminated from the study because they failed to amplify the β-globin gene. Of the remaining samples, 40% (42/105) were positive using primers MY09/11, 98% (103/105) using primers GP05+/06+, and 92% (97/105) using Nested-PCR. With the MY09/11 and GP05+/06+ techniques, it was possible to obtain 100% HPV-positive samples. In this study, the prevalence of the genotypes found was 57, 23, 5, 4 and 3% for HPV genotypes 16, 18, 31, 33 and 56, respectively. HPVs 67 and 83 were present in 2%, and genotypes 6, 11, 58 and candHPV85 were present in 1% each. The prevalence of the more common genotypes (HPV 16 and 18) in this study agrees with that reported worldwide (IC95%=0.4657-0.8976). CONCLUSIONS: to obtain more reliable results, it is necessary the use of more than one primer system to detect HPV infections. We believe that the three techniques studied are important and suitable for the clinical diagnosis of HPV, when they are appropriately combined.

PURPOSE: to evaluate the effect of hormone replacement therapy (HT) on the weight on perimenopausal women as well as the effect of different treatment regimens on this parameter. METHODS: a retrospective study of 139 women with menopause for less than 2 years, who were monitored with periodical visits in our department. We compared two groups: women who started HT (n=89) with women who had no hormonal treatment (n=50) and in the two groups, we evaluated the changes in body weight over a 1-year period. In the first group, we assessed the same parameter as a function of different treatment regimens: estrogen alone versus estrogen combined with progestin and standard dose versus low dose. The SPSS® program was used for statistical analysis, with the level of significance set at p<0.05. RESULTS: the groups were similar with respect to demographic and baseline characteristics; weight gain was higher in the untreated group (434 vs 76 g), but the difference observed was not significant (p = 0.406); among HT users, those taking estrogen alone had an increased weight gain compared to women taking estrogen with progestin (775 vs 24 g), although no statistically significant difference was observed and the same applied when comparing the dose initially prescribed (92 vs 49 g). CONCLUSIONS: despite the common belief about weight gain associated with HT, the results of the present study seem to contradict this point, with no additional weight gain beyond that normally associated with this period in a woman´s life.

PURPOSE: to investigate the micronucleation (MN) of exfoliated cells from the uterine cervix of HIV+ women according to immunocompetence status. We investigated the clinical conditions of immunocompetence by analyzing the levels of CD4+ lymphocytes and viral count for HIV (VC). METHODS: biological material was collected from 23 HIV+ patients whose cervical oncologic cytology results were negative. They were patients from the STD/AIDS-FCMS-PUCSP who underwent a cytobrush collection in the squamous columnar junction. Similar material was obtained from 19 healthy control women. The material, about 2000 cells per patient, was processed for cytology using light microscopy and an immersion objective. To analyze the immunological status of HIV+ patients we used CD4+ count and VC. Statistical analysis was performed using the Χ2 and Kolmorogov-Smirnov tests. RESULTS: twenty-three pacients composed the group of HIV+ women and 19 composed the control group. We found micronuclei (MN) in all HIV+ patients and in 84.2% of the control group. In 17 73.9% of the HIV+ patients and in 5.2% of the control group we found more than 7 MN cells. MN tended to occur more among women with poorer immunological status in the HIV+ group. CONCLUSIONS: HIV+ patients in the AIDS phase have a higher prevalence of micronucleated cells, as opposed to a control group. Also, the frequency of MN was associated with worse conditions of immunosuppression.

PURPOSE: To evaluate the quality of health care assistance during childbirth in the hospitals of Goiânia, in Brazil. METHODS: Thirteen hospitals were appraised from April to December 2007, and a random sample of 404 normal births was studied. Data were obtained from interviews with mothers after delivery and by consulting their medical records. The quality of assistance at birth was evaluated by using the Bologna score and by comparing the procedures used in those hospitals to standard recommended practices. RESULTS: The Bologna score presented an average value of 1.04 (95%CI=0.9-1.1). The elective caesarian rate was 30%, the emergency caesarian rate was 10%, and the rate of induced childbirth was 1.6% The percentage of childbirths attended by health care professionals was 100%, but pediatricians in the delivery room were present only in 30% of the time. During labor, half of the women had no evaluation of the uterine dynamics and 29% had no auscultation fetal monitoring. The partogram was used for only 28.5% of the women, whereas the use of oxytocin was 45.8%. CONCLUSIONS: The results indicate a poor quality of childbirth care with low values of the Bologna score, high elective and emergency caesarians rates, a high number of unnecessary and potentially harmful interventions, and an insufficient frequency of beneficial interventions.

PURPOSE: To analyze the effectiveness and occurrence of complications, in addition to hospitalization time and blood losses. METHODS: Thirty patients were assigned alternatively and consecutively to one of two groups (15 to the Curettage Group and 15 to the Manual Vacuum Aspiration Group). The following variables were analyzed: effectiveness of the method, occurrence of complications, time before the procedure, time of execution of the procedure, time after the procedure, and total time of hospital permanence, in addition to hematocrit and hemoglobin, which were measured before and after the procedure. Patients were evaluated clinically 10 to 14 days after the procedure. Parametric and nonparametric tests were used for statistical analysis, with the level of significance set at p>0.05. RESULTS: Both methods were efficient and no complications were recorded. Blood losses were similar in the two groups, but the hospitalization time was significantly shorter for the Manual Vacuum Aspiration Group (p=0.03). CONCLUSION: Manual vacuum aspiration is as efficient and safe as uterine curettage, with the advantage of requiring shorter hospitalization, which increases the resolution of the method, improving the quality of care for these patients.

PURPOSES: To determine the rate of low birth weight and some of the risk factors associated with this event among adolescents. METHODS: A cross-sectional study conducted between October 1994 and December 2009 at a maternity in Campinas, in Brazil, using information generated from the computerized obstetric form. After selection of adolescents who delivered at this hospital, two groups were created, with and without low birth weight, respectively. Relative risk and 95% confidence interval for all independent variables (risk factors) and the Χ2 test for some perinatal results were performed. The level of significance was set at 5%. RESULTS: During the study period, 24,000 births occurred at CAISM. Of these, 2,404 occurred among 2,357 teenagers (10.02%) and the frequency of low birth weight was 15.1%. Adolescent pregnancy recurred in 294 (8.2%). Age less than 15 years-old, anemia, smoking, and hypertension were not significantly associated with low birth weight. Antecedent of miscarriage and association with systemic lupus erythematosus increased the risk of low birth weight. Cesarean section and an Apgar score below seven were more prevalent among adolescents with low birth weight, and 85% of all adolescents had less than six prenatal visits. CONCLUSIONS: The prevalence of low birth weight is higher among adolescents than among adult women, and there was a large number of adolescents with less than six prenatal visits . The antecedent of miscarriage and the presence of systemic lupus erythematosus were risk factors associated with the occurrence of low birth weight among adolescents.
