Reticular pattern detection in dermoscopy: an approach using Curvelet Transform

Abstract Introduction Dermoscopy is a non-invasive in vivo imaging technique, used in dermatology in feature identification, among pigmented melanocytic neoplasms, from suspicious skin lesions. Often, in the skin exam is possible to ascertain markers, whose identification and proper characterization is difficult, even when it is used a magnifying lens and a source of light. Dermoscopic images are thus a challenging source of a wide range of digital features, frequently with clinical correlation. Among these markers, one of particular interest to diagnosis in skin evaluation is the reticular pattern. Methods This paper presents a novel approach (avoiding pre-processing, e.g. segmentation and filtering) for reticular pattern detection in dermoscopic images, using texture spectral analysis. The proposed methodology involves a Curvelet Transform procedure to identify features. Results Feature extraction is applied to identify a set of discriminant characteristics in the reticular pattern, and it is also employed in the automatic classification task. The results obtained are encouraging, presenting Sensitivity and Specificity of 82.35% and 76.79%, respectively. Conclusions These results highlight the use of automatic classification, in the context of artificial intelligence, within a computer-aided diagnosis strategy, as a strong tool to help the human decision making task in clinical practice. Moreover, the results were obtained using images from three different sources, without previous lesion segmentation, achieving to a rapid, robust and low complexity methodology. These properties boost the presented approach to be easily used in clinical practice as an aid to the diagnostic process.

A vivência acadêmica em um serviço de atenção psicossocial: relato de experiência / Academic experience in a psychosocial care service: an experience report

Esse artigo objetiva relatar as experiências de acadêmicas de enfermagem vivenciadas no Centro de Atenção Psicossocial (CAPS) através do Programa de Educação pelo Trabalho (PET) para a Saúde/Saúde Mental/Crack, Álcool e outras Drogas. O programa busca qualificar a formação dos futuros profissionais da saúde e é destinado a fomentar grupos de aprendizagem no âmbito da Atenção em Saúde Mental, Crack, Álcool e outras Drogas. Dentro desse contexto, o PET se insere nos serviços de saúde de forma a auxiliar e melhorar a qualidade do serviço prestado aos usuários, familiares e comunidade em que estão inseridos. No CAPS são realizadas diversas atividades, entre elas, grupos de psicofármacos, de artesanato, de atividade física, de alfabetização, de culinária, visitas domiciliares, grupos de familiares, assembleia de usuários, atendimento individual. Estas atividades contribuem no aprendizado dos acadêmicos, proporcionando uma formação cidadã com ampla visão de senso coletivo, percepção de responsabilização e compromisso social.

This article aims reporting the nursing academic experiences faced at the Center of Psychosocial Assistance (CAPS ­ in Portuguese) through the Work Education Program (PET) for Health / Mental Health / Crack, Alcohol and other Drugs. The program aims qualifying the preparation of future health professionals and is developed in order to help learning groups focused on Mental Health Attention, Crack, Alcohol and other Drugs. Within this context, the PET is present in health services in order to help and improve the quality of the service offered to users, families and the community in which these people live. At CAPS, several activities are performed, including psychotropic groups, craftwork, physical education, literacy, cooking, home visits, family groups, users' groups, and individual assistance. These activities contribute in the experience of the students, providing some citizen training with a broad vision of collective sense, perception of accountability and social commitment.

O cuidado em saúde mental no CAPS no entendimento dos profissionais / Mental care delivered in psychosocial care centers (CAPS) from the viewpoint of the professionals

Trata-se de um subprojeto da pesquisa Avaliação dos CAPS da região sul do Brasil, tendo como objetivo conhecer o entendimento dos profissionais de um serviço substitutivo sobre o cuidado em saúde mental prestado neste espaço. Estudo com abordagem qualitativa, realizado em um CAPS II. A coleta dos dados ocorreu através de entrevistas. Os dados foram classificados em três temáticas, analisados segundo a literatura disponível. Neste artigo, abordaremos a temática que trata do entendimento dos profissionais do serviço sobre o cuidado que é prestado neste local. Os resultados mostram que o cuidado para estes profissionais abrange aspectos que vão além do biológico, incluindo também a família e a sociedade. Percebemos que a equipe do serviço está ampliando seu olhar sobre a saúde mental, quando compreende a reabilitação psicossocial como o centro do cuidado.

This article deals with a subproject of the Project for Evaluation of the CAPS psychosocial care centers (CAPS) in the southern region of Brazil, whose purpose was to learn how the professionals of a substitute service feel about of the mental care delivered there. The study was conducted in a CAPS II using a qualitative approach. Data were collected in interviews. The data were classified into three thematic groups and analyzed according to the available literature. In this article we will approach the understanding of the professionals about the care services offered in the CAPS. The results show that for these professionals care involves more than the biological aspects, including the family and society. We perceive that the team is extending its perception of mental health, when considering psychosocial rehabilitation the most important aspect.
