AbstractBackground:Dermatological diseases, among which acne vulgaris, have psychological impact on the affected generating feelings of guilt, shame and social isolation.Objectives:To compare quality of life, self-esteem and other psychosocial variables amongst adolescents with and without acne vulgaris, and between levels of severity.Methods:Cross-sectional observational study in a sample of 355 high school students from the city of João Pessoa. Data collection was performed with questionnaires and clinical-dermatological evaluation. The primary variables were the incidence of AV; quality of life, set by the Children's Dermatology Quality of Life Index and Dermatology Quality of Life Index; and self-esteem, measured by the Rosenberg Self-Esteem Scale. For calculation of statistical tests, we used the SPSS 20.0 software, considering p=0.05.Results:The sample, with an average age of 16, showed 89.3% prevalence of acne vulgaris. The most prevalent psychosocial issue was "afraid that acne will never cease", present in 58% of affected youth. The median score of Quality of Life in Children's Dermatology Index was different amongst students with and without acne vulgaris (p=0.003), as well as the Quality of Life in Dermatology (p=0.038) scores, so that students with acne vulgaris have worse QoL. There was a correlation between the severity of acne vulgaris and worse quality of life. Self-esteem was not significantly associated with the occurrence or severity of acne vulgaris.Conclusions:acne vulgaris assumes significance in view of its high prevalence and the effect on quality of life of adolescents, more severe at the more pronounced stages of disease (p<0.001). The psychosocial impact of acne vulgaris should be valued in the management of patients with this condition.

FUNDAMENTOS: Na observação pessoal de dermatologistas, nutricionistas e dos próprios pacientes, um novo problema emerge nas academias de ginástica: desenvolvimento e exacerbação da acne em usuários de Whey Protein, proteínas derivadas do leite de vaca. Extratos de Whey Protein contêm fatores de crescimento que podem estar relacionados com a acne. Sua pureza e composição não são completamente conhecidas e não há investigações científicas sobre seu potencial causador de acne. OBJETIVO: Avaliar a relação entre o uso de suplementos protéico-calóricos e o aparecimento ou agravamento da acne vulgar em adultos jovens em João Pessoa - PB. MÉTODOS: Estudo observacional descritivo conduzido em academias de ginástica e em consultório de dermatologia. Cada participante foi examinado para acne em três ocasiões e acompanhado por 60 dias. RESULTADOS: Foram examinados 30 pacientes. Aparecimento ou exacerbação de lesões acneiformes foram observados (p<0,0005), sendo o efeito mais proeminente no sexo feminino e em indivíduos sem acne atual e sem história familiar de acne. CONCLUSÃO: Este estudo demonstrou o aparecimento de lesões acneiformes com o uso progressivo de suplementos proteico calóricos, ao longo de dois meses. Sugere-se que o uso deste tipo de suplemento seja desestimulado.

BACKGROUND: Based on personal observations of dermatologists, nutritionists and patients, a new problem emerges in the gyms: development and exacerbation of acne in users of whey protein, which is a protein derived from cow's milk. Whey Protein extract contains growth factors that may be related to acne. Its purity and composition are not fully known and there is no scientific research on its potential to cause acne. OBJECTIVES: Assess the relationship between the use of proteincalorie supplements and onset or exacerbation of acne vulgaris in young adults in the city of João Pessoa. METHODS: Descriptive observational study conducted in gyms and in a dermatology clinic. Each participant was examined for acne on three occasions and followed for 60 days. RESULTS: 30 patients were examined. Onset or exacerbation of acneiform lesions were observed (p <0.0005). The effect was more prominent in females and in individuals without current acne and no family history of acne. CONCLUSION: This study showed the onset of acne with the progressive use of protein-calorie supplementation, in a two-month period. It is suggested that this type of supplementation be discouraged.

A vasculopatia livedóide apresenta-se com dor e úlceras de cicatrização lenta em membros inferiores, e fisiopatologia obscura. As estratégias terapêuticas incluem cicatrizantes, antiinflamatórios e imunossupressores, sem relatos de benefício permanente. Administrou-se imunoglobulina em paciente refratário a outras terapias e avaliou-se o comprometimento da pele antes e depois por meio de escore clínico. Houve regressão significativa das lesões. A droga foi bem tolerada, e a terapia foi finalizada.

Livedoid vasculopathy presents with pain and slowly healing ulcerations of the lower limbs, and has obscure pathophysiology. Usual therapeutics include rheologic, anti-inflammatory and immunosuppressing agents with no reports of permanent benefits. Immunoglobulin was administered to a patient who was refractory to other treatments and skin involvement was assessed by means of clinical score before and after treatment. There was a significant healing of the lesions. Imunoglobulim was well tolerated and therapy was discontinued.
