Introduction: vaccination in adolescence has received growing scientific attention in recent years. This age group's vulnerability to a number of preventable diseases, including some STDs, has a relevant impact in morbimortality, and caused it to be included in the National Immunization Program (Programa Nacional de Imunização). Objective: to check the influence of vaccination in a Basic Health Unit (BHU), analyzing vaccination records, data from the Ministry of Health, and the degree of knowledge demonstrated by adolescents and their guardians regarding these preventable diseases. Method: a household survey was carried out with a selected population of adolescents and/or their guardians, within the area covered by a BHU in northeastern region of Belo Horizonte-MG. Simple random sampling was the method used and the research was performed with 210 adolescents. Results: the main age group was 15-19 years (55.23%), corresponding to teenagers who answered the questionnaire. Guardians who participated totaled 149 respondents. Vaccine coverage established by the adolescents' personal vaccination cards showed that 39 were up to date with their schedules shots, 111 were behind and 60 did not respond. Yellow fever vaccine had the lowest coverage among youths. Lack of knowledge about immunization is high among adolescents and their guardians. Conclusion: Among adolescents, vaccination coverage and knowledge about diseases and their corresponding vaccines should be improved, not only increasing vaccination but also through health education in schools.

The aim of this study is to describe a case of dentigerous cysts of a young patient successfully treated as well as clinical and radiographic follow-up. A 10-year-old female patient was referred to the Buccomaxillofacial Surgery and Traumatology Service of the Regional University Hospital of Campos Gerais. The patient's panoramic radiograph revealed a well-defined radiolucent unilocular area associated to the crown of the second permanent right lower molar, which was impacted. In addition, the permanent upper canines were enclosed, suggesting a dentigerous cyst. A conservative treatment was determined, through marsupialization of the lesions. The histopathology examination confirmed the clinical diagnosis of dentigerous cysts. Longitudinal clinical and radiographic monitoring was essential to certify the regression of the lesion, as well as bone neoformation, thus promoting the eruption and maintenance of the affected permanent teeth.

La deficiencia de hierro es la causa más frecuente de anemia en pediatría. Su detección precoz, tratamiento correcto y profilaxis adecuada, constituyen una prioridad sanitaria en nuestro país. Objetivo: Describir el screening de hemoglobina realizado en lactantes con edades comprendidas entre 8 y 12 meses, usuarios de un centro de atención pediátrico de Montevideo, en el período comprendido entre 2 de mayo y 31 de octubre de 2015 y evaluar factores de riesgo de anemia ferropénica presentes. Se revisaron sus historias clínicas, consignando datos epidemiológicos, antecedentes perinatales, alimentación recibida y si recibieron suplementación con hierro adecuada. Se registró si se había realizado la medición de hemoglobina por punción digital y el valor medido. Se comparó la prevalencia de factores de riesgo entre niños con y sin anemia. En el período evaluado fueron asistidos 62 niños: 3 pretérminos de 34 semanas o menos; 15 con peso al nacer menor a 3000 gramos; 42 con lactancia materna exclusiva durante 6 meses; 54 con alimentación complementaria adecuada; 45 con suplementación de hierro. Se realizó la medición de hemoglobina por punción digital a 55 niños. Tenían anemia 28 niños (82 % leve). No se encontró asociación de padecer anemia con los factores de riesgo estudiados excepto el cumplimiento de la profilaxis con suplemento de hierro. Concluimos que la prevalencia de anemia en este grupo fue elevada y que la suplementación con hierro es importante para su prevención.
