Prevention of repeated episodes of type 2 reaction of leprosy with the use of thalidomide 100 mg/day

BACKGROUND: Leprosy can have its course interrupted by type 1 and 2 reactional episodes, the last named of erythema nodosum leprosum (ENL). Thalidomide has been the medication of choice for the control of ENL episodes since 1965. OBJECTIVES: These episodes can repeat and cause damages to the patient. In order to prevent these episodes, an extra dose of 100 mg/day thalidomide was used during six months, followed by a follow-up period of six more months after thalidomide discontinuation. METHODS: We included 42 patients with multibacillary (MB) leprosy who had episodes of ENL. They were male and female patients aged between 18 and 84 years. RESULTS: Of the 42 patients, 39 (92.85%) had the lepromatous form and three (7.15%) had the borderline form. We found that 100% of patients had no reactional episode during the use of the drug. During the follow-up period after thalidomide discontinuation, 33 (78.57%) patients had no reactional episode and nine (21.43%), all of them with the lepromatous form, had mild episodes, which were controlled using non-steroidal anti-inflammatory. There were no thalidomide-related side effects. CONCLUSION: A maintenance dose of 100 mg/day of thalidomide showed to be effective to prevent repeated type 2 reactional episodes of ENL.

O caminho novo: o Vale Histórico da Serra da Bocaina - opulência e decadência da sub-região paraibana paulista (reintegração de um espaço geográfico 'deprimido')

A pesquisa resgata o trecho paulista do “Caminho Novo”, antiga estrada geral de São Paulo, ligação terrestre com o Rio de Janeiro, a partir do século XVIII. No chamado Vale Histórico da Serra da Bocaina, cujo relevo se apresenta muito movimentado, a cultura do café penetrou em território paulista. Esta sub-região do Vale do Paraíba tornou-se uma das mais prósperas do país. A fase posterior, de queda na produção cafeeira, transformou-a numa região “deprimida” e estagnada. Atualmente, existem esforços para, através dos diversos ramos do turismo, reativar e dinamizar esta região vale-paraibana paulista, de modo a reintegrá-la ao pujante sistema econômico de São Paulo.

Mapeamento geológico-estrutural da Sequência Canto, porção sul do Greenstone Belt do Rio Itapirucu, Bahia

The study area is located in the southern portion of Rio Itapicuru Greenstone Belt, Bahia, where were found rocks that belongs to the Canto Sequence, that comprises felsics and intermediary rocks, beyond metasediments. The studied maps and drill holes help to recognized stratigraphy column that was divided in three mains domains, from the base to the top: andesitics to felsics lavas domain, carbonaceous and metasedimentary domains. The data obtained in mapping and petrography analysis allows classify the area in three deformational phases, Dn, Dn+1, Dn+2. The metamorphism recognized according to the mineralogical associations permitted to classify a progressive regional metamorphism (lower to medium greenchist facies) till biotite zone, falling until chlorite zone due to retrometamorphism. The auriferous mineralizations are mainly related to hydrothermal veins included in the different lithologies, mainly in carbonaceous schists

Caracterização petrográfica e geoquímica das rochas encaixantes da mineralização de ouro do alvo lavra velha - Ibitiara (BA)

The Lavra Velha gold prospect is located in Ibitiara city, in the Espinhaço Setentrional physiographic domain, on the west edge of Chapada Diamantina – central part of Bahia. It is inserting on Gavião Block, a compartment of São Francisco Cráton (Almeida, 1977). The Lavra Velha gold dump is formed by an association of hydrothermal breccia lodged in acid and intermediate rocks, classifying in tonalite, granodiorite and diorite, with high alteration, cut off by a vein and venules system constituted by hydrothermal association composed by hematite, tourmaline, quarz and sericite, located in the north limit of Ibitiara granite. In the regional geological context the area is represented by Archaean rocks (Paramirim Complex) and Paleoproterozoic rocks (Ibitiara granitoid and Matinos Granite) constituted the basement, following by paleo to mesozoic pluton-vulcanic-sedimentary association of Rio dos Remédios Group, intruded by mafic rocks. It was used geochemistry and petrographic analysis compiling to field works data to characterize the rocks where the gold mineralization is inserting. Previously these rocks were classifying in volcanic rocks of Novo Horizonte Formation. Developing this monograph’s work the petrogenetic characteristics suggesting that these rocks called volcanic actually belong to Ibitiara granitoid as a portion more metamorphosed. The green schist is the predominant metamorphism in the area with low deformation, associated to high concentration of fluid circulating. The hydrothermal alteration is the process responsible for rocks modifications and strong sericitization generalize

As informações, que serviram de base para o estudo, foram obtidas através das Autorizações de Internações Hospitalares do SUS – Ministério da Saúde (DATASUS). Observou-se que as doenças cardiovasculares, no geral, levaram a mais internações e óbitos, sendo a população feminina a mais afetada. Houve um decréscimo no número de internações por pneumonia, e aumento nos casos de DPOC em mulheres. As internações por doenças respiratórias apresentaram um padrão sazonal mais marcante, principalmente pneumonia e asma

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

Metodologia para determinação de volume de detenção em pequenas bacias urbanas: o caso do córrego Wenzel, Rio Claro/SP

With the accelerated urbanization process of Brazil from the 50s, there was a disorderly occupation of spaces and consequent soil sealing. Unlike this growth, the support capacity of urban environments has not evolved in the same way, generating negative environmental impacts to the citizens. Among these impacts are the effects of flooding. In order to minimize the negative effects of extreme precipitation over cities, the government invests in corrective measures, like compensatory techniques on urban drainage, which have as a basic principle the retention and infiltration of the rainfall, dampening the peak flow and runoff. An example of applying these techniques in urban areas are the detention basins, commonly called large pools. The hydraulic design of these structures is dependent of complex data and variables, and projects involving small areas generally use simplified methods for defining the reservoirs volume of the storage (Tassi, 2005). One of these methods is presented in this study, which relates to the percentage of soil sealing to the specific storage volume (m³/ha) in combination by applying the hydrological model of the Rational Method and analyzing regional rainfall and soil occupation over the basin. Within this context, the basin of the Wenzel stream, which is located amidst the urban area of Rio Claro/SP, also presents the problems related to human occupation in its valley. Thus, by the method presented has been adjusted a curve correlating the percentage of impermeable area and the specific volume of a detention basin. For the current situation of Wenzel Basin with 82% of impermeable area, and return period of 10 years, the specific volume is 262.1 m³/ha. The presented method is consistent with the results of other studies in the area, and the expression obtained allows estimating the volume of storage required to match hydrograph pre and post-occupancy. It presents itself as a useful tool in the planning stage of...

Avaliação da regeneração natural em trechos da mata ciliar do rio Moji-Guaçu, Pirassununga-SP

O presente trabalho teve por objetivo analisar e quantificar o banco de plântulas em trechos de Mata Ciliar do Rio Moji-Guaçu situados na Academia da Força Aérea (AFA) em Pirassununga-SP. Os trechos definidos para a amostragem foram relacionados com as condições do entorno e com a estrutura da comunidade local. Foi realizada uma avaliação da diversidade e da dominância de guildas que se encontram presentes nesse compartimento da regeneração natural, o que forneceu informações das espécies que contribuem de forma mais expressiva para a manutenção da comunidade florestal, bem como aquelas respectivas a grupos funcionais que caracterizam as condições sucessionais da estrutura atual dos segmentos de mata analisados. Na análise dos parâmetros fitossociológicos encontrou-se um Índice de Shannon-Wiener (H’) de diversidade de 3,843 nits/ind, índice de equabilidade de Pielou (J’) de 0,84, e índice de dominância de Simpson de 0,034. A síndrome de dispersão zoocórica correspondeu a quase 60% das espécies, no trecho ciliar estudado. A classe sucessional das espécies não pioneiras recebeu maior destaque, representada por 50% das espécies amostradas, mas também as lianas ocorreram com expressão no banco de plântulas analisado. Embora os padrões aqui observados possam ser generalizados, no entanto com cautela, o presente trabalho traz resultados importantes, apesar de primários, pois medidas visando à preservação e à restauração florestal dependem, primeiramente, do conhecimento sobre as espécies com ocorrência na área, sua biologia e histórico de abrangência na paisagem

Levantamento estrutural da porção norte do Greenstone Belt do rio Itapicuru e dos Alvos Encantado e C1W, Bahia

The study area is located in the geological context of the northern portion of the Rio Itapicuru Greenstone Belt (GBRI), located northeast of the São Francisco Craton, Bahia State. The GBRI is known for its great economic potential for gold mineralization, looking south at Fazenda Brasileiro Mine and North Mine Maria Preta, is situated in the study área. The structural pattern of the northern portion of the Greenstone, theme of this work, is of great importance to understand the mineralization present. To characterize the structural model three geologic sections (scale 1:25000) were made with NW-SE and EW directions and detailing two mineralized targets, Encantado, located northwest of the area, near the city of Nordestina, and C1W, located near Itapicuru River, west of the Maria Preta mine. Thus, field work and petrographic analysis were conducted, that allow to indicate the existence of two structural domains characterized by the existence of a main foliation, low angle dipping main foliation and another with high dip angle, both with NW, moreover, folds occur in the area Dn-1 and post-Dn folds. Dn-1 folds are observed less frequently but they occur mainly forming an oblique foliation and the Sn is present in porphyroblasts observed in petrographic analysis, whereas in relation to the folds post Dn, there are more than one type of folding in area, which differ by the orientation of their axis, a post Dn NS and EW Dn another post. Moreover, two areas of metamorphic green schist (biotite zone) and medium amphibolite, which are directly related to the structural domains found

População e áreas de risco: o caso das inundações na área central de São José do Rio Preto-SP

The problem of flooding in urban areas exist in many cities and their causes are as varied as the areas of occupancy or Valley weatherproofing Fund areas of infiltration in the drainage basin. The anthropic activity come triggering changes and impacts on the environment for a long time, and there is a growing need to come up with solutions and strategies that minimize and reverse the effects caused these risk areas. Thus, the present work will address the case study in São José do Rio Preto-SP that is an exception, since the area that is considered of risk lies in the Centre, unlike most lying on the outskirts. This will also analyze the processes of urban expansion and the situations of social and environmental vulnerability, including their interrelations in urban scale. The physical study of the area will serve as an important basis for the work, but it will focus mainly on the population and the problems which this is being in hazardous areas. We will not join a single methodology, wharever, we will follow our knowledge to adapt what we feel that fits better, every time. The importance of this study is that in addition to identifying the problems which the local population suffers with floods, lists measures that minimize the environmental impacts arising through the fostering of public policies

Monitoramento hidrossedimentlógico da bacia hidrográfica do alto rio Sucuriú (MS) contribuinte da PCH Costa Rica

The growing demand for electricity in Brazil has stimulated the implementation of Small Hydro Power (PCH) in various regions of the country. However, the silting of reservoirs is a major problem faced by power plants and power plants. In this context, this study aimed to evaluate the data hydrosedimentological strategic points of the watershed of the Alto Rio Sucuriú (MS) to identify the possible causes siltation of the reservoir PCH Costa Rica and suggest mitigation measures. Hydrosedimentological surveys were conducted during the rainy season (February / March 2012) and drought (August 2012), and obtained data flow, discharge liquid, suspended solids and bottom and organic matter content. Based on these results it was determined that the points 2, 4, 7 and 9 are the largest contributors to sedimentation, and point 4 got most liquid discharge (38,20 m3s-1), point 7 largest discharge of solid suspension (906,3 mg L-1), points 2 and 4 major discharges solid totals (231,59 t dia-1 and 238,185 t dia-1 respectively) and point 9 higher organic matter content (22,18%) . Found greater fraction of fine sand and very fine suspended solids and solid medium sand in the background. As mitigation measures for the process of silting of the reservoir PCH Costa Rica (MS) highlights the orientation of landowners in adopting conservation measures and planting of leguminous species native to the region in symbiosis with nitrogen-fixing bacteria
