RESUMO
Se desarrolló un snack de manzana con el fin de introducir el consumo de alimentos derivados de frutas para disminuir la obesidad en escolares de Santiago de Chile. Se deshidrataron rodelas de manzanas, con la piel incluida, de variedad Fuji a 60ºC por 4 horas obteniendo un producto con 4,6 g/100 g de humedad y actividad de agua (Aw) de 0,56 . El snack de manzanas presentó 24,8 ± 0,3 g/100 g b.s. de fibra dietética y 550,16 ± 5,89 mgGAE/100 g b.s. de polifenoles lo que lo convierte en un alimento saludable, presenta además alta capacidad antioxidante medida por FRAP, con 0,59 mmolFe/100g . El análisis sensorial realizado en escolares de 8 y 12 años indica que el producto presenta alta aceptabilidad, es un producto crocante, de textura crujiente, con sabor agridulce, por lo que se constituye en una alternativa para colaciones escolares.
An apple snack has been developed with the purpose of introducing foods derived from fruit to reduce obesity in school children of Santiago, Chile. Apple slices of the Fuji variety were dehydrated, with skin included, at 60°C for 4 h obtaining a product with 4.6 g/100 g of humidity and water activity (Aw) of 0.56. The apple snack presented 24.8 ± 0.3 g/100 g b.s. of dietary fiber and 550.16 ± 5.89 mgGAE/100 g b.s of polyphenols which converts into a healthy food, it also presents high antioxidant capacity measured by FRAP, with 0.59 mmolFe/100g. The sensory analysis done in school children between the ages of 8 and 12 years old indicates that the product presents high acceptability, is a crispy product, of a crunchy texture, with bittersweet flavor, so it is an alternative for school snacks.

The effect of three storage temperatures (0, -9 and -18 degrees C) of the kiwi-fruit pulp reduced pressure concentrate, by a period of 3 months, in the physical (soluble solids, water activity, consistency and color), chemistry (pH, acidity, ascorbic acid, chlorophyll and pheophytin) and sensorial (appearance, aroma, acidity, sweetness, color and flavor) characteristics were studied. The greater deterioration was produced in the stored pulp to 0 degree C, while to -9 degrees C there is no significative differences, on the other hand, the kiwi-fruit pulp stored to -18 degrees C maintained large part of the original characteristics. It was observed that while the temperature and storage time increased, vitamin C and chlorophyll contents decreased, varying significantly consistency, color and appearance of product. The rest of the analyzed variables did not present significative differences during storage.

Con relativa frecuencia el pediatra puede encontrase frente a un paciente con signos y síntomas atribuibles a más de una enfermedad. En la medida en que se va avanzando en el diagnóstico diferencial, sin alcanzar el diagnóstico definitivo y que el tiempo va transcurriendo sin poder iniciar tratamiento, la preocupación se hace mayor. Se presenta el caso de una lactante menor femenina de seis meses, desnutrida, procedente del medio rural, y con sintomatología de aparentemente quince días de evolución a su ingreso, caracterizada por fiebre de 39ºC continua, tos seca, rinorrea anterior purulenta, adenomegalias y petequias en cuello, axilares, regiones inguinales y genitales, palidez cutáneo mucosa, hepatomegalia y esplenomegalia gigante. Después de diecisiete semanas de hospitalización, investigándose posibilidades etiológicas infecciosas para síndrome hemofagocítico, enfermedades linfoproliferativas e Histiocitosis maligna y realizados múltiples exámenes paraclínicos que incluyeron cuatro aspirados y dos biopsias de médula ósea, tres biopsias de ganglio, una biopsia hepática y citología de líquidos corporales, fue posible llegar al diagnóstico de Histiocitosis de Células de Langerhans. Se hace una revisión de esta entidad denominada por algunos autores "La enfermedad retadora"
