RESUmEnObjetivo: Comprender las experiencias vividas por los profesionales de salud de la atención primaria con la Libreta de Salud del Niño en el cuidado a la salud infantil. Método: Estudio cualitativo de abordaje fenomenológico del que participaron enfermeros y médicos de seis equipos de Salud de la Familia de Belo Horizonte, MG. Fueron realizadas 12 entrevistas no directivas, guiadas por dos preguntas orientadoras. Resultados: El análisis comprensivo de las charlas posibilitó la construcción de tres categorías que señalan las experiencias vividas por los profesionales con la libreta. Las experiencias revelaron dificultades que se derivan de las limitaciones de conocimiento acerca del instrumento; el hecho de no rellenar en la libreta las acciones de los distintos profesionales que asisten al niño; los enfrentamientos cuotidianos del proceso y la organización del trabajo de los equipos; y el desinterés de las familias con el instrumento. Conclusión: La investigación apunta caminos posibles y necesarios para mejorar la utilización de la libreta como instrumento de vigilancia integral a la salud del niño. DESCRIPTORES ABSTRACTObjective: Understanding the experiences of health professionals in primary care with the Child Health Booklet in child health care. Method: A qualitative study with a phenomenological approach, in which participated nurses and doctors from six teams of the Family Health Strategy (FHS) in Belo Horizonte, MG. In total, were carried out 12 non-directive interviews, using two guiding questions. Results: A comprehensive analysis of the speeches enabled the construction of three categories that signal the experiences of the professionals with the booklet. The experiments revealed difficulties arising from the limitations of knowledge about the instrument; incomplete filling out of the booklet by many professionals that care for children; the daily confrontations of the process and the organization of work teams; disinterest of families with the instrument. Conclusion: The research points possible and necessary ways to improve the use of booklets as an instrument of full child health surveillance.

Objetivo: identificar o perfil e as demandas de saúde de adolescentes escolares, no Município de Divinópolis, Minas Gerais. Método: estudo transversal, exploratório-descritivo, realizado com 389 adolescentes do 8º e 9º anos do ensino fundamental. Resultados: entre os participantes do estudo, 34,4% já fizeram uso de álcool, 17,7% experimentaram fumar e 7,4% fizeram uso de maconha. A maioria dos adolescentes considerou seu estado de saúde como ótimo ou bom (84,4%). Dos que iniciaram atividade sexual, 28,9% relataram não utilizar nenhum tipo de método. Percentual elevado de adolescentes mencionou solidão em algum momento da vida (77,9%) e 5,3% dos meninos envolveram-se em brigas. Conclusão: as demandas dos adolescentes relacionadas ao sexo inseguro, saúde mental fragilizada, uso de álcool e outras drogas foram identificadas como prioritárias, necessitando da atuação conjunta entre saúde e educação na construção de estratégias comuns para o atendimento das necessidades inerentes ao adolescente.

In this work were investigated the relationship between Hookworm/Schistosoma mansoni infections and allergy related risk factors in two endemic areas with distinct prevalence of infections and co-infection. The intensity of infections, eosinophilia, allergy risk factors, infections status and anti-Der p1 IgE levels before and 2 years (population 1) and 3 years (population 2) after anthelmintic treatment, were evaluated. It was observed that the population with lower prevalence and intensity of infection (population 2) had lower eosinophils counts (>600/mm3) and higher animal contact than the population with higher parasites intensity (population 1). After anthelmintic treatment the intensity of S. mansoni single infection decreased, but no changes were observed in Hookworm and co-infected individuals. The anthelmintic treatment also enhanced anti-Der p1 IgE optical density in ELISA on the subgroups that became negative for helminth infection regardless of their previous infection condition in population 1. Facing that, we evaluated the anti-Der p1 IgE reactivity index, and the ratio (after/before treatment) was significantly higher in patients co-infected before treatment. On the other hand, no association between anti-Der p1 IgE reactivity index and the intensity of infections were observed. In conclusion, effective anthelmintic therapy of subjects from endemic areas with high prevalence of Hookworm and S. mansoni infections enhances anti-Der p1 IgE levels.
