RESUMO Objetivo Investigar a associação entre indicadores da qualidade do sono e o consumo de alimentos ultraprocessados em adolescentes. Métodos Foi realizada uma revisão do tipo integrativa, estruturada com base nos critérios do Preferred Reporting Items for Systematic Reviews and Meta-Analyses. A estratégia de busca foi realizada utilizando os descritores “adolescent”, “ultra-processed foods” e “sleep” nas bases de dados MedLine, SciELO, Scopus, Lilacs e PubMed, considerando estudos originais, nos idiomas inglês, português e espanhol, publicados sem limite temporal de ano, relacionados à temática estudada. A qualidade metodológica foi avaliada por meio do Checklist for Analytical Cross Sectional Studies of the Joanna Briggs Institute. Inicialmente foram encontrados 79 artigos. Após a leitura dos títulos e resumos 17 estudos foram selecionados. Em seguida estes artigos foram lidos na íntregra e os critérios de exclusão aplicados. Apenas 09 artigos atenderam aos critérios de elegibilidade e foram selecionados para compor esta revisão. Resultados Três estudos descreveram associações entre o maior consumo de alimentos ultraprocessados e menor duração do sono em adolescentes; um estudo apresentou associação entre o consumo de alimentos ultraprocessados e a má qualidade do sono em adolescentes; um estudo descreveu a associação de maiores chances de insônia com o maior consumo de alimentos ultraprocessados. Quatro estudos não relataram resultados significativos quanto ao questionamento principal que conduz a presente revisão. Conclusão Identificou-se associação entre o consumo de alimentos ultraprocessados e modificações em aspectos relacionados à qualidade e duração do sono, bem como à capacidade de adormecer e manter um sono contínuo em adolescentes.

ABSTRACT Objective To investigate the association between sleep quality indicators and the consumption of ultra-processed foods in adolescents. Methods An integrative review was carried out, based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses criteria. The search strategy was carried out using the descriptors “adolescent”, “ultra-processed foods” and “sleep” in the MedLine, SciELO, Scopus, Lilacs and PubMed databases, considering original studies on the investigation topic published in English, Portuguese and Spanish, without any date restriction. Methodological quality was assessed using the Checklist for Analytical Cross-Sectional Studies of the Joanna Briggs Institute. Initially, 79 articles were found. After reviewing the titles and abstracts, 17 papers were selected. Following a complete review the exclusion criteria were applied. Only 09 articles met the eligibility criteria. Results Three studies described associations between greater consumption of ultra-processed foods and shorter sleep duration in adolescents; one study showed an association between the consumption of ultra-processed foods and poor sleep quality in adolescents; one study described the association of greater chances of insomnia with greater consumption of ultra-processed foods. Four studies did not report significant results regarding the main question of our survey. Conclusion An association was identified between the consumption of ultra-processed foods and adolescent changes in the quality and duration of sleep, as well as in the ability to fall asleep and maintain continuous sleep.

Abstract Sweet's syndrome is a neutrophilic dermatosis with worldwide distribution that has been associated with inflammatory autoimmune diseases, infections, malignancies, drugs, and pregnancy. The disease is idiopathic in up to 50% of patients. A 64-year-old woman, diagnosed with right limb cellulitis (4 days of evolution), was seen at our department, due to persistent cellulitis and progressive appearance of painful nodules and plaques in both shins and the right forearm (2 days of evolution). Taken together, clinical, laboratory and pathological data suggested the diagnosis of Sweet's syndrome, probably secondary to cellulitis of the right inferior limb. We suggest that cellulitis may be associated with Sweet's syndrome, a rare association in the literature.

Objetivo:Descrever as mudanças no gasto energético de repouso, na taxa de oxidação de substrato e na composição corporal em mulheres obesas mórbidas submetidas à restrição calórica de curto prazo. Métodos:Este foi um estudo prospectivo com dez mulheres obesas com índice de massa corporal maior que 40 kg/m2 e idade entre 20-50 anos. As participantes foram hospitalizadas por sete dias consecutivos e receberam uma dieta hipocalórica convencional controlada de 1200 kcal/dia. Peso corporal, índice de massa corporal, circunferência abdominal, composição corporal, gasto energético de repouso e taxa de oxidação de substratos foram avaliados no início e no final do estudo.Resultados:Reduções significativas no peso corporal (p=0,005), índice de massa corporal (p=0,005), circunferência abdominal (p=0,005), massa gorda (p=0,005) e massa livre de gordura (p=0,008) foram observadas no final do estudo. O gasto energético de repouso mostrou redução média de aproximadamente 124 kcal/dia (5%). A taxa de oxidação de substratos não apresentou mudanças estatisticamente significativas. Houve correlação importante apenas entre a redução do peso corporal e a redução da massa livre de gordura (r=0,753, p=0,012). Conclusão:Houve uma resposta adaptativa do gasto energético de repouso com restrição energética em curto prazo em mulheres obesas mórbidas, apresentando redução média de 5% do gasto energético de repouso e correlação entre a perda de peso e a massa livre de gordura, o que indica a influência da mesma na diminuição do gasto energético de repouso. Portanto, a restrição calórica de curto prazo em mulheres obesas mórbidas leva à diminuição no gasto energético de repouso e na massa livre de gordura, sugerindo uma rápida adaptação do gasto energético.

Objective:The objective of this study was to describe changes in the resting energy expenditure, substrate oxidation rate, and body composition in morbidly obese women subjected to short-term caloric restriction. Methods:This was a prospective study that included ten obese women with body mass index greater than 40 kg/m2 and aged between 20-50 years. The participants were hospitalized for eight days and received a controlled conventional low-calorie diet, 1200 kcal/day, for seven days. Body weight, body mass index, abdominal circumference, body composition, resting energy expenditure, and substrate oxidation rate were evaluated at the beginning and at the end of the study. Results:A significant reduction in body weight (p=0.005), body mass index (p=0.005), abdominal circumference (p=0.005), fat mass (p=0.005) and fat-free mass (p=0.008) was observed at the end of the study. There was an average reduction in resting energy expenditure of approximately 124 kcal/day (5%). Substrate oxidation rate did not show statistically significant changes. There was a positive correlation only between body weight reduction and fat-free mass reduction (r=0.753; p=0.012). Conclusion:There was an adaptive response of the resting energy expenditure with short-term energy restriction in morbidly obese women with a 5% reduction in resting energy expenditure and a positive correlation between weight loss and the fat-free mass, which indicates the influence of fat-free mass on the decrease in resting energy expenditure. Therefore, short-term caloric restriction in morbidly obese women led to a decrease in resting energy expenditure and fat-free mass, which suggests a rapid adaptation of energy expenditure.

Abstract Syringoma is a benign, adnexal tumor of the eccrine sweat gland ducts. Eruptive syringomas are a rare variant, occurring before or during puberty in most cases. A 57-year-old man was observed in our department, with a 10-year history of multiple brownish papules (1-4mm in diameter), localized on the neck, shoulders, trunk and axillae. The clinical diagnosis was cutaneous mastocytosis. Histopathological examination from a papule in the trunk was compatible with the diagnosis of syringoma. The patient was treated with isotretinoin, without any improvement. The clinical diagnosis of eruptive syringoma is diffi cult and histological examination is crucial for its diagnosis. Long-term morbidity is not associated with syringomas; they are treated for cosmetic reasons with unsatisfactory results.

Kikuchi's disease is a benign, self-limiting disease, whose pathogenesis remains unknown. Patients most often present with cervical lymphadenopathy, sometimes associated with fever and leukopenia. It has been reported that up to 40% of patients with Kikuchi's disease have also cutaneous eruptions, but no specific skin changes have been described. Kikuchi's disease can be subclassified into three histologic subtypes: a proliferative type, a necrotizing type and a xantomathous type. Most patients with Kikuchi's disease require no specific treatment, because the disease regresses spontaneously, within a few weeks to months. We report a case of a 31-year-old woman with xanthomatous type of Kikuchi's disease, whose first manifestation was the onset of erythematous papules with central suppuration on her face and on her left hand.
