Two cross-sectional studies on schistosomiasis mansoni were done in Comercinho, Minas Gerais (Brazil), at an interval of 7 years. In 1974 and 1981 feces examinations (KATO-KATZ method) were done in 89 and 90% of the population (about 1,500 inhabitants) and clinical examinations were done in 78 and 92% of the patients who excreted Schistosoma mansoni eggs in the feces, respectively. The rate of infection by S. mansoni did not change (69.9% in 1974 and 70.4% in 1981), but the geometrical mean of eggs per gram of feces (431 ± 4 and 334 ± 4, respectively) and the rate of splenomegaly (11 and 7%, respectively) decreased significantly in 1981, when compared to 1974. This reduction was observed only in the central zones of the town (zones 1-2) where the rate of dwellings with piped water increased from 17 to 44%. In the surroundings (zones 3-4), where the proportion of houses with piped water did not change significantly between 1974 (10%) and 1981 (7%), the geometrical mean of S. mansoni eggs and the rate of splenomegaly did not change either.

Introduction: The geographical distribution of dentistry schools has been the object of study in Brazil and in other parts of the world. Aim: To analyze the distribution of dentistry schools in Minas Gerais state in 2016. Methodology: This is a cross-sectional study. The analysis of the courses distribution was carried out by regions and cities and categorized by public or private schools. All the institutions addresses were geocoded and mapped to illustrate the spatial distribution of dental courses across Minas Gerais state. Results: In Minas Gerais were found 30 Dentistry schools that 23 (76.66%) were private and 7 (23.34%) public. The largest number of schools were located in metropolitan regions with better socioeconomic indicators The number of annual vacancies the dentistry courses offered the 2.911 vacancies in the Minas Gerais state that 2.310 are in private schools and 601 in public courses.Conclusion: The distribution of courses were irregular and concentrated in regions with better socioeconomic conditions.

<p>Com a saturação do turismo convencional e com o surgimento de novas modalidades de turismo, as áreas naturais protegidas vêm recebendo um fluxo crescente de visitantes para prática do turismo natural (atividade turística que utiliza o Patrimônio Natural como atrativo), tendo como consequência o aumento da pressão dos recursos naturais, ampliando a preocupação com os impactos gerados por tal atividade. Para a prática desse turismo, em quase sua totalidade, as trilhas são utilizadas como ligação e meio de contato entre o homem e a natureza. No entanto, esse contato acaba provocando alguns impactos negativos nas trilhas. Sendo assim, o objetivo deste trabalho foi o de caracterizar o uso da trilha e avaliar suas condições, bem como propor alternativas de manejo que possam promover o uso sustentável da Trilha das Macaúbas localizada na Floresta Nacional de Ritápolis, Minas Gerais. Para realização desse levantamento, a trilha foi dividida em diversos segmentos nos quais foram utilizadas três metodologias: AST – Área Seccional Transversal; Penetrometria; Tabela de Indicadores. Os dados obtidos permitiram avaliar os impactos causados pelo uso da trilha, tais como: compactação do solo do leito da trilha; perda de solo no leito da trilha; danos na vegetação e borda da trilha; etc. Assim, são propostas algumas alternativas de manejo para diminuição e mitigação dos impactos causados na trilha.</p><p><strong>Abstract</strong></p><p>With the saturation of conventional tourism and the rise of new kinds of tourism, some protected areas have been receiving and increasing flow of visitors for the practice of natural tourism (tourist activity which uses the natural heritage as an attraction), resulting in the increase of the pressure on natural resources, maximizing the concern over the impacts produced by such activity. For the practice of this kind of tourism, the trails are almost entirely used as a link and means of contact between man and nature. However, this contact ends up causing some negative impacts on the trails. Therefore, the objective of this study was to characterize the use of the trails and evaluate their conditions as well as propose management alternatives that can promote the sustainable use of the Macaúbas Trail, located in the Ritápolis National Forest, Minas Gerais State, Brazil. To perform this survey, the trail was divided into several segments in which three methods were used: CSA - Cross Sectional Area; Penetrometry; Indicators chart. The obtained data allowed the evaluation of the impacts caused by the use of the trails, such as: the compaction of soil in the trail bed, the loss of soil in the trail bed, the damage to the vegetation and to edge of the trail. Thus, some management alternatives are proposed in order to reduce and mitigate the impacts on the trails.</p><p><strong>Keywords</strong><strong>: </strong>Protected Areas, trail management, ecotourism.</p><p> </p>

A clinical-epidemiologic study of schistosomiasis mansoni was conducted in the population of Ponte do Pasmado, a village in the municipality of Itinga, state of Minas Gerais, Brazil. Faecal Parasitology by the Kato-Katz method and clinical examination were performed in 93.8% and 82.8% of the local population, respectively. A socioeconomic survey was also made and the signs and symptoms presented by the patients were recorded, as well as their contacts with natural waters. The rate of Schistosoma mansoni infection was 50.3%; the peak of infection occurred during the second decade of life; there was a predominance of low egg counts in faeces (85.89% of positive patients eliminated less than 500 eggs per gram of faeces); the splenomegaly rate was 1.23%. When the risk factors for S. mansoni infection were studied, significant risks were detected in activities such as fetching water, washing dishes, bathing, and crossing streams.
