    Brazil is a country of continental dimensions with a large heterogeneity of climates and massive mixing of the population. Almost the entire national territory is located between the Equator and the Tropic of Capricorn, and the Earth axial tilt to the south certainly makes Brazil one of the countries of the world with greater extent of land in proximity to the sun. The Brazilian coastline, where most of its population lives, is more than 8,500 km long. Due to geographic characteristics and cultural trends, Brazilians are among the peoples with the highest annual exposure to the sun. Epidemiological data show a continuing increase in the incidence of nonmelanoma and melanoma skin cancers. Photoprotection can be understood as a set of measures aimed at reducing sun exposure and at preventing the development of acute and chronic actinic damage. Due to the peculiarities of Brazilian territory and culture, it would not be advisable to replicate the concepts of photoprotection from other developed countries, places with completely different climates and populations. Thus the Brazilian Society of Dermatology has developed the Brazilian Consensus on Photoprotection, the first official document on photoprotection developed in Brazil for Brazilians, with recommendations on matters involving photoprotection

    Exercícios terapêuticos nas desordens temporomandibulares: uma revisão de literatura

    No full text
    A articulação temporomandibular faz parte do sistema estomatognático que, junto com os dentes, periodonto, coluna cervical, crânio e cintura escapular, é responsável pela mastigação, fonação, deglutição, respiração e expressão facial. Exercícios terapêuticos têm sido empregados na reabilitação e prevenção das disfunções temporomandibulares (DTM). Este estudo teve como objetivo revisar a literatura a respeito, verificando a eficácia dos exercícios terapêuticos nas DTM. Foram examinados periódicos do período entre 1991 e agosto de 2008, nas bases de dados Medline, Lilacs e Pubmed, utilizando as palavras-chave "desordem temporomandibular", "terapia por exercícios" e as correspondentes em inglês. Foram selecionados relatos de caso, artigos de revisão e ensaios clínicos com mais de 20 pacientes, num total de 53 artigos. A maioria relatou efeitos positivos na redução da dor, melhora da mobilidade e dos aspectos psicológicos, sugerindo que os exercícios podem contribuir no tratamento da DTM. Entretanto, o tipo, tempo de duração, número de repetições, freqüência e intensidade dos exercícios não está bem descrita. A falta de padronização das pesquisas, bem como da forma de avaliar, dificultam a comparação dos resultados. Mais estudos com métodos padronizados devem ser estimulados.The temporomandibular joint is part of the stomatognathic system, which comprises a complex set of orofacial structures, including teeth, cervical spine, cranium and shoulder. The system is responsible for masticatory, phonation, and deglutition functions, as well as for breathing and facial expression. Physical therapy exercises have been used for rehabilitation and prevention of temporomandibular disorders (TMD). The purpose of this study was to review studies on the subject and assess the effectiveness of physical therapy exercises for TMD. Case reports, review articles, and clinical trials with more than 20 patients, published from 1991 to mid-2008, were searched for in databases Medline, Lilacs and Pubmed, by using keywords "exercise therapy" "temporomandibular disorders", and the correspondent terms in Portuguese. Fifty-three studies were selected of which most showed positive effects on pain reduction, improvement in joint mobility and psychological aspects, suggesting that physical therapy exercises may be beneficial in TMD treating. However, the type, duration time, repetitions, frequency and intensity of the therapeutic exercises are not well described. The lack of research and assessment method standardization hinder result comparison. More studies with standardized methods must be stimulated
