Views93See morePURPOSE: To investigate the impact of pregnancy on female sexual function. METHODS: An analytical, cross-sectional study was conducted on 181 non-pregnant and 177 pregnant women aged 18 to 45 years. The study included premenopausal, sexually active women with a steady partner and excluded those taking antidepressants or with a diagnosis of depression. Eleven of these women (6.2%) were in the first trimester, 50 (28.2%), in the second trimester and 116 (65.5%), in the third trimester of pregnancy. The evaluation consisted of an interview in which the Female Sexual Function Index (FSFI) was applied. The data were analyzed using the Statistical Package for the Social Sciences (SPSS) software, version 16.0. The nonparametric Mann-Whitney test was used to compare the mean FSFI values of pregnant and non-pregnant women. RESULTS: Sexual dysfunction was 40.4% among pregnant women and 23.3% among non-pregnant women, with a significant difference between the scores of the studied groups (p=0.01). The difference in the mean global FSFI values between the groups was also significant (p<0.0001). There were significant differences between pregnant and non-pregnant women regarding desire (p<0.0001), excitation (p=0.003), lubrication (p=0.02), orgasm (p=0.005) and satisfaction (p=0.03). The same was not observed regarding pain. CONCLUSION: We conclude that pregnancy negatively influences female sexual function, particularly the desire and excitement domains, revealing the importance of addressing the issue by professionals dealing with pregnant women.

Views77See morePURPOSE: To evaluate the prevalence and factors associated with intimate partner violence (IPV) among women users of Basic Health Units (BHU) in the State of São Paulo. METHODS: This was a cross-sectional descriptive study based on secondary data analysis of women users' interviews at 75 BHU in the State of São Paulo, from August/2008 to May/2009. We used a questionnaire based on the Abuse Assessment Screen and the Conflict Tactics Scales modified by the Violence Against Women Study (VAW), structured and pre-tested. The variables studied were the types of IPV (psychological, physical and sexual) and sociodemographic variables (age, education, race, paid work, religion, marital status and economic class). We interviewed 2,379 women aged 18 to 60 years. RESULTS: The prevalence of lifetime IPV was 55.7%, and the prevalences of psychological, physical and sexual IPV were 53.8, 32.2 and 12.4%, respectively. Women without a partner but previously married, with schooling <8 years and belonging to the lower economic class had a higher risk for all types of IPV, and other factors were also associated with psychological and sexual IPV. CONCLUSIONS: The prevalence of IPV is high. Healthcare professionals in primary care should make an attempt to detect IPV.

Views121See morePURPOSE: To evaluate the prevalence of Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (NG) among women candidates to in vitro fertilization (IVF) in a reference public service in southeastern Brazil. METHODS: Women who were referred for IVF from April 1st, 2008 to December 31st, 2009 were enrolled sequentially in the study. A ginecological-obstetrical background questionnaire was applied and endocervical swab samples were obtained to search for CT and NG using hybrid capture and PCR. The variables studied were: age, color, education, duration of infertility, number of pregnancies and living children, history of miscarriage, ectopic pregnancy, number of sex partners, pelvic inflammatory disease (PID), pelvic surgery, manipulation of the uterine cavity, smoking, and illicit drug use. The women were distributed according to the presence/absence of confirmed chlamydia infection and descriptive analysis was employed. RESULTS: Among 176 women tested the prevalence of CT infection was 1.1% and there was no NG infection. Two thirds of the women were >30 years old, with schooling >8 years and <5 years of infertility, and 56.2% had no children. The main background data were pelvic surgery (77.8%), manipulation of the uterine cavity (62.5%) and PID (27.8%). The tubal factor was the most prevalent, 73.3% of women (from 129), 37.5% had been sterilized, 35.8% had not been sterilized, and other factors had a prevalence <30%. CONCLUSIONS: CT and NG infections had a low prevalence in this sample. Studies at other centers in the country are needed to confirm the prevalence of infection in this particular group of infertile women.

Views193PURPOSE: To assess the prevalence of bacterial vaginosis and to compare the accuracy of testing pH and KOH with the Nugent gradient, the gold standard for the diagnosis of bacterial vaginosis (BV) in asymptomatic and symptomatic pregnant women at low risk. METHODS: We conducted a cross-sectional study on 321 pregnant women with gestational age between 14 and 26 weeks, 218 of them asymptomatic and 103 with vaginal complaints suggestive of bacterial vaginosis. All women were assessed by the criteria of Nugent and subjected to the measurement of vaginal pH and to the 10% KOH test. The Kappa coefficient was used to evaluate the methods in terms of diagnostic agreement. RESULTS: Most patients were adolescents (mean age 21.0±5.6 years), nulliparous and mulattos. The prevalence of bacterial vaginosis was 33.3% as estimated by the pH and KOH method and 35.5% by the Nugent method. Excellent agreement of the methods was found among asymptomatic pregnant women, with 72.5% of them showing negative results to both tests, which resulted in a high Kappa coefficient (k=0.82). The group of symptomatic women showed 49.5% positivity to both diagnostic methods, with excellent agreement (k=0.74). CONCLUSION: The prevalence of bacterial vaginosis determined by both the pH and KOH method and the Nugent score was high. The pH and KOH method can diagnose bacterial vaginosis as accurately as the Nugent criterion.

Views97See morePURPOSE: To assess the prevalence of Streptococcus agalactiae, a Group B streptococcus, in pregnant women, and their possible risk factors, as well as the impact of perinatal colonization and antimicrobial susceptibility. METHODS: We evaluated 213 pregnant women from 20 weeks of gestation, regardless of risk factors, attending a tertiary teaching hospital. The technique used was a single sterile swab to collect secretions from the vaginal and perianal regions. The newly obtained samples were stored in Stuart transport medium and taken to the laboratory, where they were inoculated in Todd-Hewitt selective medium supplemented with Gentamicin (8 ug/mL) and nalidixic acid (15 ug/mL), with subsequent cultivation on blood agar plates. The materials were tested with Gram, catalase with hydrogen peroxide and CAMP (Christie, Atkins, Munch-Petersen), and results were serologically confirmed with the Streptococcal Grouping Kit, Oxoid®. The positive samples were tested for antimicrobial susceptibility. We also assessed socioeconomic, reproductive, clinical, and obstetric variables, and newborn care. Statistical analysis was performed with Epi-Info 6.04. RESULTS: The prevalence of colonization obtained by field tests was 9.8% by CAMP test, but only 4.2% by serology. The only protective factor was white skin color (p=0.01, 0.45>OR>0.94, 95%CI). There was no difference in prevalence of Group B streptococcus regarding other reproductive and obstetric variables. Infection occurred in only one of the newborns from colonized mothers; although it was revealed infection with Pseudomonas spp. High resistance to ampicillin (4/9), cephalothin (4/9), penicillin (4/9), erythromycin (3/9), clindamycin (7/9), and cloramphenicol (1/9) was detected. CONCLUSIONS: The infection rate was lower than that found in other studies, although a high rate of resistance to antibiotics commonly used for treatment was detected. Since there are no studies on the prevalence of Group B streptococcus in Ceará, we cannot perform a comparative analysis of the population, and further studies are needed with geographically similar groups to validate these results.

Views114See morePURPOSE: 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).

Views121See morePURPOSE: to determine the prevalence of Chlamydia and gonorrhea in a sample of women from Curitiba. METHODS: this was a cross-sectional study with a sample of sexually active non-pregnant women aged between 16 and 23 years-old, with an intact uterus, with up to four sexual partners, without evidence of fever or purulent cervicitis, submitted to pelvic examination and PCR-based urine- testing for Chlamydia and gonorrhea. Exclusion criteria included: vaccination for HPV, vaccination history for the past 21 days, previous abnormal cytology, history of genital warts, splenectomy, immune disorders, and use of immunosuppressive drugs. An interview regarding sociodemographic and obstetric data and gynecological risk behavior for sexual transmitted diseases was applied. For statistical analysis, we used the c2 or Fisher’s exact test to assess the association between variables. RESULTS: the prevalence of Chlamydia and gonorrhea infection in the study group was 10.7 and 1.5%, respectively, and the rate of coinfection was 0.9%. No correlation was found between the age range of the volunteers, the onset of sexual activity, the number of sexual partners and of new sexual partners in the last six months, and the presence of Chlamydia or gonorrhea. In women who had vaginal discharge or ectropion, the prevalence of Chlamydia infection was two times higher than in those without such signs. CONCLUSIONS: the results of this study were similar to national studies using PCR in urine samples for the detection of Chlamydia and gonorrhea in samples of non-pregnant women of the same age groups and with the same background. Since the volunteers with more than four sexual partners and those who had purulent endocervicitis were excluded, it is believed that the prevalence of Chlamydia and gonorrhea infection could have been greater in this population.

Views96See morePURPOSE: 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.

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.
