ABSTRACT

This essay makes a theoretical reflection upon possible conceptual proximities between the contemporary application of Mindfulness in education and the educational proposals of Paulo Freire. The study manages to approximate Freire to Mindfulness through a few concepts such as "openness to the new" and 'critical curiosity', which are related to a certain kind of development of awareness. We conclude that the contributions of mindfulness to the educational process as understood by Paulo Freire are related to the ability to develop a state of presence that brings more awareness to mental and emotional states, as much as it leads to conscious actions opposed to actions in the autopilot. Awareness (which is close to the concept of action-reflection in Freire) becomes, thus, a keyword for transformation towards lesser mental, emotional, physical and social/interpersonal suffering, both in Freire and in Mindfulness.(AU)


Este ensayo proporciona una reflexión teórica sobre la posible proximidad conceptual entre la aplicación contemporánea de Mindfulness (atención plena) en la educación y las propuestas educativas de Paulo Freire. El estudio consigue aproximar los conceptos de Freire del cuadro de referencia de la Atención Plena, por medio de conceptos tales como "apertura a lo nuevo" y "curiosidad crítica", relacionados con cierto tipo de desarrollo de la conciencia (awareness). Se concluye que las contribuciones de la atención plena para el proceso educativo, conforme entendido por Paulo Freire, se relacionan con la capacidad de desarrollar un estado de presencia que brinde más conciencia de los estados mentales y emocionales, además de llevar las acciones conscientes en oposición a las inconscientes. La conciencia, concepto próximo al de reflexión-acción en Freire, se convierte, por lo tanto, en una palabra clave para la transformación hacia la disminución del sufrimiento mental, emocional, físico y social/interpersonal, tanto en Freire como en Mindfulness.(AU)


Este ensaio traz uma reflexão teórica sobre a possível proximidade conceitual entre a aplicação contemporânea de Mindfulness (Atenção Plena) na Educação e as propostas educacionais de Paulo Freire. O estudo consegue aproximar os conceitos de Freire do quadro referencial da Atenção Plena, por meio de conceitos como "abertura ao novo" e "curiosidade crítica", relacionados a certo tipo de desenvolvimento da consciência (awareness). Conclui-se que as contribuições da Atenção Plena para o processo educacional, conforme entendido por Paulo Freire, relacionam-se à capacidade de desenvolver um estado de presença que traga mais consciência aos estados mentais e emocionais, além de levar a ações conscientes em oposição a ações inconscientes. Consciência, conceito próximo ao de reflexão-ação em Freire, torna-se, portanto, uma palavra-chave para a transformação em direção à diminuição do sofrimento mental, emocional, físico e social/interpessoal, tanto em Freire quanto no Mindfulness.(AU)

ABSTRACT

Abstract

Scleredema adultorum of Buschke is a rare disorder characterized by diffuse swelling and non-pitting induration of the skin usually involving the face, neck, arms and upper trunk. It has been associated with previous infectious diseases, diabetes, paraproteinemia and, more rarely, malignant neoplasms or autoimmune disorders. We report the case of a 30-year-old man who presented with a 2-year history of scleredema. Further investigation led to the diagnosis of primary Sjögren’s syndrome. The association between scleredema and autoimmune disorders has been rarely seen. To our knowledge, there are no other reports describing the association between primary Sjögren’s syndrome and scleredema adultorum of Buschke.

ABSTRACT

Several variants of dermatofibroma have been described. They are essentially distinguished by their clinical and histopathological features. To review the mainfeaturesof these variants, a retrospective study of skin biopsies and tissue excisions of dermatofibromasperformed in the dermatology and venereology service at the Hospital Garcia de Orta between May 2007 and April 2012 was carried out. During that period, 192 dermatofibromas were diagnosed in 181 patients, the lesions being more common in women. Median age of the study population was 48 years. The most common lesion site was the limbs (74% of patients). The histopathological types found were common fibrous histiocytoma (80%) and the aneurysmal (5.7%),hemosiderotic (5.7%), epithelioid (2.6%), cellular (2.1%), lipidized (2.1%), atrophic (1.0) and clear cell (0.5%) variants. Based on these findings, this review focuses on the clinical and histological features of the various variants of dermatofibroma in terms of their clinical presentation, distinct histopathological features, differential diagnosis and prognosis.

ABSTRACT

BACKGROUND: Ingrown nails are a very common problem. There are different stages of disease and diverse therapeutic options. Phenol and sodium hydroxide are commonly used agents for chemical matricectomy but both frequently entail excessive healing times. OBJECTIVE: This prospective study aimed mainly to evaluate the efficacy of partial nail avulsion and selective chemical cauterization of the matrix using 80% TCA in the treatment of the ingrowing nail. METHODS: One-hundred-and-thirty-three patients with 197 ingrown toenails were included in this study. Preoperatively, we tried to find predisposing factors to the disease. In the postoperative period, patients were evaluated for potential complications at days 3, 30, 180, 270 and 360. Pain was measured before surgery, as well as 24 hours and 72 hours after surgery. RESULTS: There were only 3 cases (out of 197) of ingrown nail recurrence. Preoperatively, we found the presence of drainage in 82% of patients, which, following the first visit after surgery, was reduced to 19%. Persistent granulation tissue was found in 3% of the patients (versus 75% prior to surgery). The most frequent predisposing factors for the ingrown nail were excessive trimming of the lateral nail plate (63%), plantar hyperhidrosis (58%) and heavy nail folds (39%). Pain was substantially reduced after surgery. CONCLUSION: It is assumed that chemical procedures for the ingrown toenail are associated with delayed healing times but our results demonstrated quick recovery. Using 80% TCA for selective matricectomy in the ingrown toenail is an effective, quick and easy method. .


FUNDAMENTO: A unha encravada é uma patologia muito frequente. A doença engloba diferentes estadios existindo diferentes soluções terapêuticas. O fenol e o hidróxido de sódio são largamente utilizados na matricetomia química porém ambos cursam com longos tempos de cura. OBJETIVO: O principal objectivo deste estudo prospectivo foi avaliar a eficácia da mactricectomia com ácido tricloroacético a 80% no tratamento da unha encravada. MÉTODOS: Foram incluídos no estudo 133 doentes com 197 unhas encravadas. Factores predisponentes foram avaliados pré-operatoriamente. No período pós-operatório os doentes foram avaliados para potenciais complicações ao dia 3, 30, 180, 270 e 360. A dor foi avaliada antes da cirurgia, 24 horas e 72 horas depois da cirurgia. RESULTADOS: Ocorreram apenas 3 (em 197) casos de recorrência da unha encravada. Antes da cirurgia registou-se exsudação em 82% dos doentes sendo que na primeira visita após a cirurgia este número foi reduzido para 19%. Observou-se ainda tecido de granulação persistente em 3% dos doentes (versus 75% antes da cirurgia). Os factores predisponentes mais frequentemente encontrados para unha encravada foram o corte excessivo da porção lateral da placa ungueal (63%), hiperhidrose plantar (58%) e pregas ungueais espessadas (39%). A dor teve uma redução dramática após a cirurgia. CONCLUSÃO: É assumido que os procedimentos químicos para a unha encravada estão associados com longos tempos de cura mas os nossos resultados mostraram uma rápida recuperação. No tratamento da unha encravada a matricectomia parcial com ácido tricloroacético a 80% é um método rápido, eficaz e de fácil execução. .

ABSTRACT

Fitobezoares são estruturas formadas pela agregação de fibras, principalmente vegetais, no trato digestivo de ruminantes, ocasionando obstruções intestinais que podem levar o animal à morte. Informações sobre a formação desse aglomerado ainda são escassas. Neste estudo, são identificados os principais componentes de fitobezoares bovinos, e descrita as estruturas anatômicas das folhas de três espécies de Stylosanthes SW.: S.capitata Vogel, S. macrocephala M. B. Ferreira & S. Costa, S. guianensis var. vulgaris M.B. Ferreira & Sousa Costa cv. 'Mineirão' e S. guianensis (Aubl.) Sw. As plantas selecionadas são utilizadas na dieta do gado e potenciais formadoras do fitobezoar. Os fitobezoares foram fragmentados para análise de sua composição e analisados seguindo-se as técnicas da anatomia vegetal. As fibras e cristais encontrados em fitobezoares são similares aos observados nos feixes esclerenquimáticos presentes nos folíolos das espécies de Stylosanthes avaliadas. Nossos resultados apontam diferenças na abundância de fibras nos folíolos de cada espécie. S. macrocephala é a variedade que sugere maior potencial para formação de fitobezoares no trato digestivo de animais que se alimentam dessa leguminosa, devido a abundância de fibras e cristais presentes na folha. Os feixes esclerenquimáticos, idioblastos e a abundância de cristais de oxalato de cálcio nas espécies Stylosanthes podem potencializar a formação de fitobezoares em ruminantes, em especial quando essas leguminosas são consumidas em excesso.


Phytobezoars are structures formed by the aggregation of primarily plant fibers in the digestive tract of ruminants, causing intestinal obstruction that can lead to the death of an animal. Information about the formation of these clusters is scarce. This study identified the main components of bovine phytobezoars and described the leaf anatomy of three species and one variety of Stylosanthes SW.: S.capitata Vogel, S. macrocephala B. Ferreira & S. Costa, S. guianensis var. vulgaris M.B. & Sousa Ferreira Costa cv. 'Mineirão' and S. guianensis (Aubl.) Sw. These plants are used as feed for livestock and probably contribute to the formation of phytobezoars. The phytobezoars were fragmented for analysis of their internal composition and were studied according to plant anatomy techniques. The fibers and crystals found in phytobezoars were similar to the sclerenchyma fiber bundles found in Stylosanthes. The comparative analysis of Stylosanthes showed differences in the abundance of fibers in the leaflets of each species. S. macrocephala is the variety that may have the highest potential for formation of phytobezoars in the digestive tract of animals because there was an abundance of fibers and crystals present in the leaf. The sclerenchyma bundles, idioblasts, and the abundance of calcium oxalate crystals in Stylosanthes species may potentiate the formation of phytobezoars in ruminants, particularly when these legumes are consumed in excess.
