RESUMO

Objetivo: Traduzir e realizar a adaptação transcultural do questionário Patient's Awareness in Psoriasis (Conhecimento do Paciente sobre Psoríase) para o contexto e idioma português do Brasil e avaliar suas propriedades psicométricas. Métodos: Este trabalho foi realizado por meio de um estudo transversal. O delineamento do estudo foi correspondente à derivação de um questionário para a vigilância e controle em saúde, seguindo metodologia sugerida pela Sociedade Internacional para Farmacoeconomia e Pesquisa de Resultados - Grupo de Trabalho para Tradução e Adaptação Cultural. Primeiro, um questionário piloto foi aplicado a 10 pacientes com psoríase para avaliar compreensibilidade. Depois, outros 115 pacientes foram caracterizados e responderam ao questionário de forma autorreferida. Trinta e um pacientes responderam ao questionário mais uma vez, uma semana mais tarde. Foi avaliado: o coeficiente de correlação intraclasse, o coeficiente alfa de Cronbach, o erro padrão de medição e feita análise fatorial exploratória. Resultados: O coeficiente de correlação intraclasse foi 0,91 (0,82 - 0,96) e o alfa de Cronbach global foi 0,79. Todos participantes responderam 'não' à questão n.º 10 (suprimida nas avaliações psicométricas). A análise fatorial indicou três fatores principais: 1. Evolução clínica, 2. Aspectos clínicos e Qualidade de vida e 3. Expectativa de cura e tratamento (itens distribuídos com cargas > 0,400 ). Conclusões: O estudo resultou em uma versão do questionário que contribui com o desenvolvimento de estudos, com futuros que objetivarem aprimorar a avaliação clínica dos pacientes e a tomada de decisões relacionadas à vigilância e controle da psoríase no Brasil.

Objective: To translate and perform the cross-cultural adaptation of the Patient's Awareness in Psoriasis questionnaire to the Brazilian context in Brazilian Portuguese idiom and assess its psychometric properties. Methods: This assignment was conducted within a cross-sectional study. The study design corresponded to the derivation of a questionnaire for health surveillance and control, following the methodology suggested by the International Society for Pharmacoeconomics and Outcomes Research - Task Force for Translation and Cultural Adaptation. First, a pilot questionnaire was given to 10 psoriasis patients to assess comprehensibility. Then, another 115 patients were characterized and responded to it (self-reported manner). Thirty-one patients retook the questionnaire a week later. The intraclass correlation coefficient, Cronbach's alpha, standard error of measurement, and the exploratory factor analysis were determined. Results: The intraclass correlation coefficient was 0.91 (0.82 - 0.96). Overall, Cronbach's alpha was 0.79. All participants answered 'no' to question #10, which was restrained in the psychometric assessments. Factor analysis indicated three main factors: 1. Clinical evolution, 2. Clinical aspects and quality of life and 3. Healing and treatment (items distributed with loads > 0.400). Conclusions: The study resulted in a version of the questionnaire that contributes to the development of future studies, to the clinical evaluation of patients and to decision-making related to the surveillance and control of psoriasis in Brazil.

RESUMO

The potential of tuber flour of Ipomoea batatas (L.) Lam. cv. Brazlândia Branca (white sweet potato) as wound healing and antiulcerogenic agent was investigated in vivo in animal model. Excision on the back of Wistar rats was performed to induce wounds that were topically treated with Beeler's base containing tuber flour of white sweet potato at 2.5%. Number of cells undergoing metaphase and the degree of tissue re-epithelialization were investigated 4, 7 and 10 days post-treatment. The protective effect of aqueous suspension of tuber flour (75 and 100 mg/kg animal weight) on gastric mucosa of Wistar rats was also studied by using the ethanol-induced ulceration model. Ointment based on white sweet potato at 2.5% effectively triggered the healing of cutaneous wound as attested by the increased number of cells undergoing metaphase and tissue re-epithelialization regardless the time of wound treatment. Tuber flour potentially prevented ethanol-induced gastric ulceration by suppressing edema formation and partly protecting gastric mucosa wrinkles. Crude extracts also exhibited potential as free radical scavengers. The results from animal model experiments indicate the potential of tuber flour of white sweet potato to heal wounds.
