Logullo, Patricia;Carvalho, Heráclito Barbosa de;Saconi, Renata;Massad, Eduardo;
Sao Paulo Medical Journal , 2008, DOI: 10.1590/S1516-31802008000300006
Abstract: context and objective: the success of vaccination campaigns depends on the degree of adherence to immunization initiatives and schedules. risk factors associated with children's failure to receive the measles vaccine at the correct age were studied in the city of s?o paulo, brazil. design and setting: case-control and exploratory study, in the metropolitan area of s?o paulo. methods: the caregivers of 122 children were interviewed regarding their perceptions and understanding about the measles vaccination and the disease. results: the results showed that age, region of residence, marital status and education level were unrelated to taking measles vaccines adequately. most individuals remembered being informed about the last annual vaccination campaign by television, but no communication channel was significantly associated with vaccination status. the answers to questions about knowledge of the disease or the vaccine, when analyzed alone, were not associated with taking measles vaccinations at the time indicated by health agencies. the results showed that, when parents felt sorry for their children who were going to receive shots, they delayed the vaccination. most of the children did not take the measles vaccination on the exactly recommended date, but delayed or anticipated the shots. conclusion: it is clear that there is no compliance with the government's recommended measles vaccination schedule (i.e. first dose at nine and second at 15 months of age, as recommended in 1999 and 2000). feeling sorry for the children receiving shots can delay vaccination taking.

Abstract: context and purpose: uterine cervical ectopy (cervical erosion) is today considered to be a physiological condition, but there still seems to be a strong tendency towards treating it. the purpose of this study was to review the medical literature for evidence regarding benefits from treating cervical ectopy. methods: the following databases were reviewed: medical literature analysis and retrieval system online (medline), excerpta medica database (embase), literatura latino-americana e do caribe em ciências da saúde (lilacs) and cochrane library databases. in addition, six medical textbooks were consulted. results: the review showed that: 1) there is probably an association between ectopy and higher risk of chlamydia trachomatis, human papillomavirus and human immunodeficiency virus infection; 4) there is probably an association between ectopy and cervical intraepithelial neoplasia; 5) there is an association between ectopy and mucous discharge and nocturia; and 6) there is no evidence of an association between ectopy and cervical cancer, or of protection against cervical cancer associated with ectopy treatment. conclusions: 1) no data were found in the medical literature to support routine treatment for ectopy; 2) treatment could be recommended for symptom relief, but more symptoms are attributed to ectopy than could be demonstrated in a controlled study; 3) further studies to test the hypothesis of protection against cervical cancer associated with treatment are necessary.

Abstract: objective: to estimate hiv prevalence and identify high-risk sexual behavior for infection in pregnant women who were given prenatal assistance. methods: cross-sectional study based on attendance records of 8,002 pregnant women (25% of all municipalities) who lived in 27 municipalities in southern brazil in 2003 and had anti-hiv tests done in a testing and counseling center that performed prenatal assistance. sociodemographic and behavioral data were gathered, as well as syphilis and hiv test results, during the individual counseling sessions registered in the data bank of the sistema de informa??es dos centros de testagem e aconselhamento (information system on testing and counseling centers). women who sought the centers for confirmation of previous serology or were referred to this service due to the presence of aids symptoms were excluded from the data base. results: a total of 0.5% of all the pregnant women analyzed (ci 95%=0.3;0.6) were hiv positive. the only variable associated with hiv seropositivity was schooling. the majority of them were basically exposed through unprotected sexual intercourse with the only partner they had a steady relationship with. younger pregnant women who were single, unemployed and had lower level of education constituted the group with highest exposure. conclusions: the sistema de informa??es dos centros de testagem e aconselhamento turned out to be useful for the epidemiological surveillance of hiv infection and high-risk behavior among pregnant women and could also be useful as regards other populations.

Abstract: the purpose of this study was to assess the relationship between mode of delivery and maternal complications, based on a retrospective cohort of all births at a public hospital in 2003. complications included: infection, hemorrhage, hysterectomy, uterine rupture, lesions in adjacent organs, deep venous thrombosis, and pulmonary embolism. the analysis used odds ratio (or), chi-squared test, and fisher's exact test, besides logistic regression. fifteen complications were identified. taking vaginal delivery as the reference, an association was found between cesarean section and overall complications. analysis of confounding showed an association between hypertension, hiv, placenta previa, and abruptio placentae. after controlling for these variables, an association remained between overall complications and cesarean section (or = 9.7; p = 0.04). another analysis comparing elective cesareans and vaginal deliveries also showed an increased risk for cesarean (or = 4.7; p = 0.02). finally, comparing elective cesareans with trial of labor, we found an increased proportion of complications in elective cesareans, with borderline significance (or = 3; p = 0.058). we concluded that cesarean section is associated with maternal morbidity, even after controlling for confounders.

Abstract: Objectives To examine the independent and combined association of physical activity (PA) and sedentary behavior (SB) on both systolic (SBP) and diastolic blood pressure (DBP) in adolescents from two observational studies. Methods Participants from two cross-sectional studies, one conducted in Europe (n = 3,308; HELENA study) and the other in Brazil (n = 991; BRACAH study), were selected by complex sampling. Systolic and diastolic blood pressure (outcomes), PA and SB, both independently and combined, and potential confounders were analyzed. Associations were examined by multilevel linear regression. Results Performing the recommended amount of PA (≥60 min/d) attenuated the effect of SB on DBP in BRACAH study girls and in boys from both studies. In contrast, PA did not attenuate the effects of SB on the SBP of girls in the HELENA study. The combination of less than recommended levels of PA with 2–4 h/d of sedentary behavior was found to be associated with increased SBP in boys from both studies. Conclusions Meeting current PA recommendations could mediate the association between SB and DBP in both sexes. In boys, the joint effect of low levels of PA and excessive sedentary activity increases SBP levels. Longitudinal studies are required to confirm these findings.

Abstract: surveys of risky behavior relating to hiv/aids are generally made for groups at risk of infection, for which hiv/aids prevalence is usually expected to be higher than in the general population. therefore, an educational homepage in portuguese was created on the internet to inform/ask internauts regarding knowledge and behavior. the internauts were classified as adolescents (13 to 25 years) and adults (>25 years). the number of stds was reported as 1. 8 ± 2. 6 infections (range: 1 to 20 infections); 43% used condoms during sexual intercourse. alcohol consumption was reported by 63% and illicit drug use by 32% (marijuana 24% and inhalants 15%). among the adolescents, 31% did not classified alcohol as a drug. the adults more frequently reported homosexuality, anal intercourse and stds, although the adolescents also presented high rates of risky behavior. these results show the need to reach out to internauts through better control strategies. different types of strategies must be encouraged, in order to reach people that use this means of communication and entertainment.
