Globalização, iniqüidade e doença de Chagas Globalization, inequity and Chagas disease

A doença de Chagas (tripanossomíase americana), apresenta múltiplos aspectos sócio-culturais e político-econômicos que envolvem questões de iniqüidade e globalização. São relações presentes tanto nos processos de produção da doença como nas possibilidades de sua prevenção e manejo. Apesar da pobreza da região, envolvendo questões de iniqüidade e globalização, a doença tem sido controlada em várias áreas, o que reforça a auto-estima dos países. Para o futuro, problemas e desafios podem ser esperados, principalmente em termos da assistência médica para os indivíduos já infectados e da sustentação de uma vigilância epidemiológica permanente. Ambos estes pontos dependem de um melhor desempenho dos sistemas nacionais de saúde, principalmente em termos de sua competência e da superação de situações de iniqüidade. Particularmente, tem cabido à comunidade científica e acadêmica latino-americana um papel de grande destaque na implementação e sustentação de políticas de controle da doença, que hoje evoluíram para estratégias de ação compartida entre países, o que pode significar importante avanço no contexto político da região.<br>Chagas disease (American trypanosomiasis) bears a close relationship to multiple social and political aspects involving issues of globalization and inequity. Such relations concern the process of disease production and control in parallel with medical management. Despite the poverty in Latin America and various problems related to inequities and globalization, Chagas disease has been controlled in several areas, a fact that reinforces the countries' self-reliance. Several problems and challenges related to the disease can be expected in the future, mainly concerning medical care for already infected individuals and the sustainability of effective epidemiological surveillance. Both points depend heavily on improved performance by the national health systems, principally in terms of their efficiency and their capacity to overcome inequity. A particularly important role has been attributed to the Latin American scientific and academic community in the implementation and sustainability of efficient control policies. Control activities have now evolved towards internationally shared initiatives, a major new stride forward in the region's political context

Quality of life measurement in alopecia areata. Position statement of the European Academy of Dermatology and Venereology Task Force on Quality of Life and Patient Oriented Outcomes

New treatment options may lead to an increased interest in using reliable and sensitive instruments to assess health-related quality of life in people with alopecia areata (AA). The purpose of this paper is to present current knowledge about quality of life assessment in AA. The dermatology-specific Dermatology Life Quality Index (DLQI) was the most widely reported health-related quality of life instrument used in AA. Three AA-specific (Alopecia Areata Symptom Impact Scale, Alopecia Areata Quality of Life Index and Alopecia Areata Patients' Quality of Life) and three hair disease-specific instruments (Hairdex, Scalpdex and ‘hair-specific Skindex-29’) were identified with a range of content and validation characteristics: there is little evidence yet of the actual use of these measures in AA. Scalpdex is the best-validated hair disease-specific instrument. Further extensive validation is needed for all of the AA-specific instruments. The European Academy of Dermatology and Venereology Task Force on Quality of Life and Patient Oriented Outcomes recommends the use of the dermatology-specific DLQI questionnaire, hair disease-specific Scalpdex and the alopecia areata-specific instruments the Alopecia Areata Symptom Impact Scale or Alopecia Areata Quality of Life Index, despite the limited experience of their use. We hope that new treatment methods will be able to improve both clinical signs and health-related quality of life in patients with AA. In order to assess the outcomes of trials on these new treatment methods, it would be helpful when further development and validation of AA-specific instruments is being encouraged and also conducted
