Técnica do grupo focal como método de avaliação do conhecimento de adolescentes sobre saúde bucal

This study aims to the understanding of adolescents regarding oral health, using the Focus Group technique. The study was conducted at three public schools in the city of Araçatuba, São Paulo State, Brazil, with ten students in each. In order to conduct the focus groups, the following words, which featured high error levels, were addressed in survey questions on oral health: oral health; plaque, permanent teeth; fluoride; gum bleeds?; dental floss; transmission of cavities. During the discussions in the focus groups, it was observed that many teenagers were surprised at the situation to which they were submitted and at the topic they were discussing. The word 'oral health' was associated with the condition of cleanliness of the oral cavity, not identifying oral health as part of general health. The term 'transmission of cavities' did not have a sufficient understanding. The term 'permanent tooth' was well understood and was associated with a type of tooth that would not be replaced. The word 'fluoride' had more association with the task of cleaning than protection of the teeth. It is concluded that the use of the focus group technique is of great importance in the interpretation of the knowledge of adolescents on oral health and the appropriateness of the terminology of questionnaires on the same subject.

Avaliação da reatividade cruzada entre antígenos de Leishmania spp e Trypanosoma cruzi na resposta sorológica de cães pela técnica de imunofluorescência indireta (RIFI)

Visceral Leishmaniasis (VL) is a zoonosis caused by Leishmania spp. protozoa. Dog is the main parasite's reservoir, especially in urban areas. Indirect Immunofluorescent Antibody Test (IFAT) is commonly used for canine visceral leishmaniasis (CVL) diagnosis, by detection of antibodies against the parasite. However, Trypanosoma cruzi (T.cruzi) cross reactions can occur in serological diagnosis. In order to evaluate the occurrence of cross reactions between antigens of Leishmania spp. and T.cruzi, 150 blood samples of CVL epidemiological inquiry positive dogs were collected and sera were tested by IFAT. Dogs were culled at Zoonosis Control Center of Bauru (SP), an endemic area for VL. Another 150 dogs' blood samples were collected in Botucatu (SP), a non endemic area for LV, and sera were also tested by IFAT. Serum samples of dogs from Bauru were positive, both for Leishmania spp. and for T. cruzi, showing high cross-reactions incidence, reinforcing the need of diagnosis confirmation by other tests. Serum samples of dogs from Botucatu demonstrated low prevalence of positive results by IFAT, both for Leishmania spp. and T.cruzi. However, despite the low number of positive serological results for these parasites, the epidemiological and serological investigation for LV and Chagas disease in dogs from Botucatu must be kept, considering the importance of dog as domestic reservoir for both parasites.

Aplicação de técnica de geoprocessamento em áreas degradadas de mata ciliar e sua correlação com qualidade da água numa subbacia hidrográfica

Studying the physical environment of a watershed is the basic condition for a successful planning of the riparian forest preservation, and for water production and conservation. The aims of the present study were to analyze and quantify the spatial and temporal evolution (1984 and 2010) using Landsat-5 satellite images of Cintra Stream sub-watershed, Botucatu, São Paulo State, Brazil, processed by the software IDRISI Andes, as well as to analyze the water quality through the parameters pH, EC, DO and BOD5 at 4 different sites in the years 1999, 2008 and 2009. Considering the 1076.48ha area of the sub-watershed, the pasture class of 1984 was reduced by 25.55% in 2010, resulting in an increase in the remaining classes. The most important class was native forest and reforestation since it had an increase of 5.08%, which indicates recovery of the riparian forest. Degraded areas were identified close to the inferior limit of the sub-watershed (P3 and P4), as well as local contamination (P1 and P2) with worsening of the water quality in the remaining sites in the periods 2008 and 2009. Recovery and management of the ecological succession of degraded areas and water quality monitoring at 1 and 2 sites will be necessary to reestablish the natural condition of the area studied.
