Soroprevalência de testes rápidos (ML Flow) em casos de hanseníase e contatos intradomiciliares em municípios endêmicos do Pará

A hanseníase, doença milenar, ainda constitui um grande desafio para a saúde pública, inclusive no que se refere a diagnóstico precoce e vigilância em saúde. Com objetivo de estimar a soroprevalência de anticorpos antiPGL-1 através do teste rápido ML-Flow em casos de hanseníase e seus contatos intradomiciliares de municípios endêmicos do Pará, realizou-se um estudo transversal incluindo 73 casos novos de hanseníase e 135 contatos intradomiciliares, selecionados no período de abril de 2011 a janeiro de 2012, nas unidades de referência para tratamento de hanseníase nos municípios de Belém, Marituba, Igarapé-Açú e Santarém. Os resultados demonstraram uma prevalência de 14,8/10.000hab de casos de hanseníase entre os contatos examinados. A soropositividade do ML Flow nos casos índices foi de 53,42% em pacientes multibacilares e 13,33% nos contatos intradomiciliares. Houve associação direta de positividade do ML Flow nos contatos intradomiciliares com o índice baciloscópico do caso índice. Não houve associação direta do tempo de convivência e a consanguineidade do caso índice em relação ao teste ML Flow. Houve associação entre a positividade do teste ML Flow e a realização da vacina BCG entre os contatos. Estes resultados indicam que a introdução do teste ML Flow poderia servir como instrumento auxiliar no monitoramento dos casos e seus contatos, tornando-se de grande relevância na vigilância epidemiológica da hanseníase.

Epidemiologia espacial e sorológica da hanseníase no estado do Pará

Mais de 80.000 casos de hanseníase foram diagnosticados nos últimos 20 anos no Pará e, ainda hoje, com um coeficiente de detecção anual de 50/100.000 habitantes (três vezes superior à média nacional) a doença permanece como um grave problema de saúde pública neste Estado. O objetivo geral deste estudo foi desenvolver um método integrando a epidemiologia espacial e sorológica como ferramenta de combate à hanseníase no Pará. Inicialmente, foram realizadas visitas domiciliares a famílias de pessoas afetadas pela hanseníase, diagnosticadas nos últimos cinco a seis anos, em oito municípios de diferentes regiões do Estado. A equipe de pesquisadores com experiência no manejo da hanseníase, composta por médicos dermatologistas, enfermeiros, fisioterapeutas e técnicos de laboratório, realizou exame clínico dermatoneurológico em 1.945 contatos intradomiciliares de 531 casos notificados e coletou amostra de sangue para pesquisa sorológica de anticorpos IgM anti-PGL-I. Além disso, 1.592 estudantes de 37 escolas públicas do ensino fundamental e médio, com idade entre 6 e 20 anos, também foram selecionados aleatoriamente para serem submetidos à mesma avaliação. As residências dos casos notificados, bem como a dos estudantes incluídos no estudo foram georreferenciadas para a análise da distribuição espacial da hanseníase. Dois anos mais tarde, com base na informação sorológica prévia, a equipe de pesquisadores retornou a dois municípios para reavaliar os indivíduos incluídos no estudo. Adicionalmente, duas novas escolas públicas localizadas em áreas de alto risco de hanseníase, determinadas pela análise da distribuição espacial da doença em um dos municípios, foram selecionadas para avaliar-se a importância da informação geográfica na detecção de casos novos. Na avaliação inicial, 156 (8%) contatos e 63 (4%) estudantes foram diagnosticados como casos novos de hanseníase; 806 (41,4%) contatos e 777 (48,8%) estudantes foram soropositivos para anti-PGL-I. A análise da distribuição espacial dos casos registrados da doença em um dos municípios selecionados indicou que a hanseníase apresenta um padrão heterogêneo, com clusters de alta e baixa taxa de detecção anual em áreas específicas da cidade (p < 0,01), e que 94,7% dos estudantes examinados residiam a menos de 200 metros de um caso registrado durante os seis anos anteriores ao estudo. No seguimento, a incidência de hanseníase foi significativamente maior entre os indivíduos soropositivos (22,3%) quando comparados aos soronegativos (9.4%) (OR = 2,7; IC95% = 1,29 – 5,87; p = 0,01); também foi significativamente mais alta entre moradores de residências com pelo menos um sujeito soropositivo (17,4%), comparada aos de residências sem nenhum morador soropositivo (7,4%) (OR = 2,6; IC95% = 1,18 – 5,91; p = 0,02). A seleção de escolas localizadas em áreas de maior risco dentro do município aumentou significativamente a eficiência na detecção de casos novos entre escolares (8,2%), quando comparada aos resultados obtidos em escolas selecionadas aleatoriamente (4%) (p = 0,04). Os dados mostram alta taxa de prevalência oculta de hanseníase e de infecção subclínica pelo M. leprae no Pará. A epidemiologia espacial e sorológica são ferramentas eficazes para aumentar a detecção precoce de casos novos e deveriam ser utilizadas pelos municípios do Pará para que o Estado possa finalmente alcançar as metas de controle da hanseníase.

Partial time use of anterior repositioning splints in the management of TMJ pain and dysfunction: a one-year controlled study

This study aimed at evaluating the effectiveness of partial use of anterior repositioning appliances in the management of TMJ pain and dysfunction when compared to stabilization splints and a control group in a one-year follow-up. Sample was initially constituted by 60 patients, randomly divided into three groups: I- stabilization splints, II- repositioning splints and III- no treatment. The whole sample was evaluated by means of TMJ and muscle palpation, mandibular AROM, analysis of occlusal contacts, joint sounds inspection and Visual Analogue Scale (VAS) for one year; 52 patients composed the final sample. A significant (after 15 days) improvement in pain report (VAS) and palpation index was found for group II (p≤0.01). The occurrence of occlusal alterations as posterior open bite or gross interferences after the splint therapy and increased muscle tenderness were not problems in this study. Similar results in joint noises reduction were observed for the entire sample. It was concluded that controlled partial use of repositioning splints is a beneficial tool in the management of intra-articular pain and dysfunction, with no risks of irreversible occlusal changes.

High rates of undiagnosed leprosy and subclinical infection amongst school children in the Amazon Region

Leprosy in children is correlated with community-level factors, including the recent presence of disease and active foci of transmission in the community. We performed clinical and serological examinations of 1,592 randomly selected school children (SC) in a cross-sectional study of eight hyperendemic municipalities in the Brazilian Amazon Region. Sixty-three (4%) SC, with a mean age of 13.3 years (standard deviation = 2.6), were diagnosed with leprosy and 777 (48.8%) were seropositive for anti-phenolic glycolipid-I (PGL-I). Additionally, we evaluated 256 house-hold contacts (HHCs) of the students diagnosed with leprosy; 24 (9.4%) HHC were also diagnosed with leprosy and 107 (41.8%) were seropositive. The seroprevalence of anti-PGL-I was significantly higher amongst girls, students from urban areas and students from public schools (p < 0.0001). Forty-five (71.4%) new cases detected amongst SC were classified as paucibacillary and 59 (93.6%) patients did not demonstrate any degree of physical disability at diagnosis. The results of this study suggest that there is a high rate of undiagnosed leprosy and subclinical infection amongst children in the Amazon Region. The advantages of school surveys in hyperendemic areas include identifying leprosy patients at an early stage when they show no physical disabilities, preventing the spread of the infection in the community and breaking the chain of transmission.

CARACTERIZAÇÃO GEOLÓGICA, PETROGRÁFICA E GEOQUÍMICA DO MACIÇO SARARÉ NA PARTE SUDOESTE DO CRÁTON AMAZÔNICO

O Maciço Sararé ocorre no sudoeste de Mato Grosso, intrusivo no Domínio Jauru, e encontra-se controlado por trend tectônico NW-SE ligado a tectônica regional transcorrente e, tardiamente, por feições tectônicas rúpteis NE-SW. É constituído por três fácies petrográficas principais denominadas biotita-monzogranito, muscovita-monzogranito e monzogranito, que apresentam contatos transicionais. São rochas leucocráticas, de cor vermelha a rosada, isotrópicas e eqüi/ineqüigranulares a localmente porfiríticas. Os dados geoquímicos as classificam como rochas do tipo S, peraluminosas, alto K, quimicamente restritas e evoluídas em relação a SiO2 alcançando teores em torno de 75%. Os valores de REE apresentam-se dispostos em três curvas assimétricas, evidenciando fácies distintas e mostrando uma redução destes valores e das anomalias de Eu para a fase final. O maciço representa intrusões diferenciadas, geradas a partir da fusão de material da crosta superior em ambiente de colisão continental no final do evento Aguapeí-Sunsás.

Estudo clínico de prevalência de sinais e sintomas de disfunções craniomandibulares e contatos oclusais cêntricos em pacientes portadores de lesão labiopalatal

A clinical investigation was undertaken to find out the prevalence of craniomandibular signs and symptoms in a group of 11 patients with labiopalatal lesions. The number and distribution of occlusal contacts was evaluated through questionnaire, clinical examination and analysis of mounted casts in partially adjustable articulators in the position of maximum inter cuspation. The most frequent signs and symptoms were articular sounds and lateral pterygoid muscle tenderness to palpation followed by restriction of mouth opening and sensation of tiredness. The number of occlusal contacts was small, mean of 5 contacts per patient, and the site was considered as atypical, 62% of them were on inclined plane surfaces , suggesting occlusal instability. The frequency of signs and symptoms was low and they were of a mild character. The most prevailing signs of craniomandibular dysfunction - articular sounds, muscular tenderness to palpation and restriction of mouth opening - was noticed in only one of the patients

Remoção de cromo de resíduos de curtumes por argilitos da formação Corumbataí - SP

The tanning wastes are characterized to be significant sources of pollution in the hydrosphere when non adjusted or disposed adequated form. That happens because this industry type uses the chromium to tan hides, and this element is present in discharges concentrations in final wastes, characterizing this waste type as dangerous, according to the Associação Brasileira de Normas Técnicas, através da Norma Brasileira 10.004 de 2004. Due to this, the research proposes a form to reduction chromium of the tanning wastes through the process of adsorption. For that were used mining-wastes of Corumbataí Formation clays, material commonly used in the production of ceramic products in Rio Claro (SP). They were accomplished laboratory essays that involved the preparation of different clays pulps and subsequent mixture of these with the tanning wastes, maintaining them under different mixing times and adsorption contacts. After the separation of the mixtures, the leached were chemically analyzed and it was seen the efficiency of chromium reduction and your relationship with the variation of different times of contact clays/wastes and different grain sizes used in the pulps preparation.

Identificando tipos de personalidade na dança de salão

Many studies have shown a variety of benefits that the practice of Ballroom Dancing can bring, such as leisure and entertainment, the release of tension from a stressful routine, improving relationships, expanding social contacts. The rationale of this study is by the need to evaluate a different sphere of life of people involving the structure that is the personality. The man is humanized in contact with other men and the culture it is almost impossible to grow it in isolation, that is, are the social relationships that allow men to become human and her personality structure. The relationship brought about by the ballroom dancing can benefit the development of personality or simply put individuals in situations that provide a greater understanding of yourself, as this activity has characteristics that greatly facilitate social contact between people who practice it as the relationship between gentleman and lady for a dance, the contact with people in different classes, social events where it is practiced and even the music that is danced. This work aimed to be able to identify the type or types, the most common personalities exist in one group of participants in a course of Ballroom, based on the technique of Enneagram developed and disseminated by Gurdjieff, whose characteristic is to divide into nine different personality types. Participants were 42 students of the extent to ballroom dancing. We administered a questionnaire to identify the personality of each participant and then there was a second observation time the behavior of six participants in the class for confirmation of your psychological type to issofoi used a checklist developed by the author. Was also investigated whether there are differences of gender and psychological types who seek more such activity. The conclusions are that there are a large number of persons type 9, more than 42% and are predominantly male, since... (Complete abstract click electronic access below)

Litofácies e relações estratigráficas da formação Aquidauana no nordeste da Bacia do Paraná - São Sebastião do Paraíso (MG)

The Aquidauana Formation is characterized by sandstones of variable granulation, mudstones and diamectites abundant in clay, typical colors like brick red (vermelho tijolo) of glacial, fluvial and lacustrine origin. It’s chronostratigraphic equivalent to the Itarará group from the Neo Carboniferous age, that under the exploratory view, such units represent important intervals in the basin, occurring together with them minerals as well as energy resources as petroleum, underground water and coal – what requires a great paleogeography and stratigraphy knowledge for its exploration. By gathering information from the columnar sections of the area, it was possible to characterize the sedimentary facies, the stacking pattern as well as the association. It was also made an attempt of stratigraphic correlation, which showed great difficulties since glacial environments present a great lateral discontinuity of the facies besides the complex relationship process of formation. As a result, it was obtained 8 sedimentary facies, the lateral and vertical relations and genesis process. It is proposed that the sedimentary environment in the study area is the fluvio glacial, characterized by alluvial systems formed by defrosted water which transport the sediments that are deposited in plains in front of the glacier (distal outwash). Petrographic thin section analysis showed that the transportation process was ineffective. The grains present punctual to lobular contacts, characterizing good porosity and permeability to the rock, varying these qualities according to more or less existence of matrix. The presence of Iron Oxide deposited between the recrystallization border and feldspathic mineral indicates that this rock has possibly presented a primary rubefaction, intensified by alkaline fluid percolation

Caracterização petrográfica das zonas de alteração hidrotermal associadas aos pegmatitos da mina Bom Futuro, Rondônia

The Bom Futuro tin deposit is located in Ariquemes, north-central state of Rondônia. Since its discovery in the late 80s, the tin deposit of Bom Futuro has been explored and considered one of the leading Brazilian producers of cassiterite, exploring it mainly in secondary deposits (placers) in the vicinity of the hill Bom Futuro. The primary mineralization occurs in the contacts between quartz veins and pegmatites with the rocks of the hill and its exploitation has been the goal of new studies in the area. These bodies occur in all rock types of the hill, leading edges of hydrothermal alteration with each rock. The focus of the study is the characterization of hydrothermal alteration through the analysis of the edges of pegmatitic veins intruded on each of the main rock types found on the hill Bom Futuro, which are: biotite gneiss, biotite amphibolite, subvolcanic breccia, topaz leucogranite, topaz leucoriolito and micro melassienito porphyry. The analysis and comparison showed familiarities between the edges of alteration encountered, and possible subdivision into three main zones: the inner zone or the vein itself, intermediate zone or transition zone and the change zone where the passage of hydrothermal features to rocks features is gradual. The cassiterite and sphalerite were found scattered in three zones, however in larger quantities in the intermediate zone, near the contact
