A anorexia nervosa e fatores associados em adolescentes do sexo feminino, em município do sul do Brasil / In anorexia nervosa and associated factors in female adolescents city in south of Brazil

Objetivo foi investigar a prevalência de sintomas de anorexia nervosa e a sua associação com o Índice de Massa Corporal (IMC), e com satisfação e dimensão corporais, em adolescentes do sexo feminino. Trata-se de um estudo de base populacional, do tipo transversal, realizado com 407 adolescentes entre 14 e 19 anos, e incluiu a avaliação do IMC, o Eating Attitude Test, e a Escala de Silhuetas Corporais. A associação entre as variáveis dependente e independente foi realizada por meio da análise univariada, seguida da multivariada com ajuste do modelo logístico. A prevalência dos sintomas de anorexia foi de 15,97%, sendo que as adolescentes insatisfeitas com a sua imagem corporal têm 2,56 (IC 1,11-5,83) mais chances de desenvolver sintomas de anorexia. A maioria delas apresentou-se eutrófica (83,78%), e não foi observada relação entre o IMC e presença de sintoma de anorexia. Os resultados sugerem que a insatisfação corporal está relacionada à presença do sintoma de anorexia, indicando a necessidade de uma atuação multidisciplinar junto à população estudada.

The objective was to identify the prevalence of anorexia nervosa symptoms and its associations with body mass index (BMI) and body size satisfaction among female adolescents. It is a cross-sectional population based study of 407 adolescents aged between 14 and 19, including the BMI assessment, the Eating Attitude Test and the Silhouette Scale. The association between the dependent and independent variables was performed by the univariate analyses and followed by a multivariate analysis with adjusted logistic model. The prevalence of symptoms of anorexia nervosa was 15.97%, and the adolescents who are dissatisfied with their body image have 2.56 (IC 1,11-5,83) times increased risk of developing symptoms of anorexia. Most of them are eutrophic (83.78%), and there was no connection between the presence of symptoms of anorexia and the BMI. The results suggest that body dissatisfaction is related to the symptoms of anorexia, which indicates the need of a multidisciplinary performance with the population.

Câncer gástrico de origem estromal: relato de caso / Gastric Gastrointestinal Stromal Tumor (GIST)

Gastrointestinal Stromal Tumor (GIST), despite rare, is the most common digestive tract mesenchymal tumor. Modern histogenesis studies have shown its stromal origin and not a muscular origin as it had been believed before. Diagnosis is made through immunohistochemical studies (CD- 117) and treatment is achieved with surgery followed by chemotherapy and has good results. The authors describe a case of gastric GIST discovered after upper gastrointestinal bleeding presentation, and treated successfully.
