The present study aims to analyze the prevalence and risk factors of active pediculosis and to compare the efficacy and sensitivity of the vacuum method with the comb method and the visual inspection with a magnifying glass in order to determine the best methodology to detect active pediculosis among schoolchildren from Paraná state. Each child was examined by the three methods in sequence and a playful activity was introduced to increase the children likelihood to participate in the study. Additionally, hair characteristics and other risk factors as sex, age, and area of living were take into consideration to measure epidemiological aspects. From a total of 358 schoolchildren from southern Brazil, overall pediculosis prevalence was 45.5%, while active pediculosis prevalence was 13.1%. Regarding active pediculosis, there was no statistical difference among sex. However, nine-year-old girls were most likely to have active pediculosis. The vacuum method was 5.96 and 11.29 times more efficacious than the magnifying glass method and the comb method, respectively, and also had higher sensitivity (74.5%) in detecting active pediculosis. When analyzing hair characteristics, children with long and wavy/curly hair were more often diagnosed by the vacuum method than children with short and wavy/curly hair. The vacuum method was the most effective method and proved to be an optimal option to detect active pediculosis among schoolchildren, mostly in children with wavy/curly hair.

AbstractThis study investigated the epidemiological factors that contribute to the seroprevalence of Toxoplasma gondii and Toxocara spp. in children from Paraná state, Brazil. Immunoglobulin G (IgG) antibodies to T. gondii were detected using indirect immunofluorescence, and IgG antibodies to Toxocara were detected using an enzyme-linked immunosorbent assay. For each individual, a questionnaire was completed that contained epidemiological and clinical data. The data analysis was performed using multiple logistic regression. Of the 544 children investigated, 3.2% presented co-infection with T. gondii and Toxocara spp. Of this total, 7.4% were positive for antibodies to T. gondii, and 25% were positive for antibodies to Toxocara spp. The presence of antibodies to Toxocara spp. increased the risk of T. gondii infection (P= 0.029). Children who were 1–8 years of age were less infected by T. gondii than those who were 9–12 years of age. The variables that influenced positivity for anti-Toxocara spp. were the origin of the children and contact with sand. Children with positive serology for Toxocara spp. presented more eosinophilia compared with those with non-reactive serology. Infection with both parasites reveals the need for preventive measures, such as guidance about modes of infection, parasite control and monitoring recreational areas.

In order to describe the changing patterns of risk factors for HIV-1 transmission of patients using hospital services at an AIDS referral centre in Porto Alegre, southern Brazil, data on demographic characteristics, referral patterns and risk factors at time of first presentation were collected prospectively on 405 patients between October 1985 and September 1991. Overall HIV-related patient workload increased during the study period, as did the proportion of infected female patients seen ( P < 0.05). Of all patients, 147 (36%) presented with symptomatic HIV disease and 77 (19%) presented with an AIDS defining condition; men were more likely to present with symptomatic disease than women. Approximately 156 (44%) of men were self-referred compared with 4 (8%) of the women ( P < 0.0001). Of the 357 infected men, 82 (23%) were bisexuals; of the 26 heterosexually infected women, 7 (24%) had bisexual male partners. These data suggest the increasing importance of heterosexual HIV transmission in this hitherto ‘low’ prevalence area, with male bisexuals constituting an important route through which heterosexual females are being infected in this area. The data also suggest that heterosexual women in Southern Brazil do not perceive themselves to be at risk for HIV-1 infection.
