RESUMO A prática regular de exercício físico promove a melhoria do estado geral de saúde e é fundamental para a prevenção de um grande número de patologias, entre as quais se encontram as doenças músculoesqueléticas. A promoção da atividade física e dos seus efeitos benéficos para a saúde têm contribuído para o rápido crescimento do número de crianças e adolescentes envolvidos em atividades desportivas organizadas ou recreativas que, infelizmente, tem sido acompanhado por um significativo aumento do número de lesões relacionadas com a sua prática. Tendo em conta que o sistema músculo-esquelético das crianças e adolescentes se encontra ainda em desenvolvimento, a sobrecarga associada, em especial, à prática de modalidades desportivas de competição poderá ter reflexos de longo prazo para a sua saúde. Este artigo visa fazer uma revisão bibliográfica sobre os principais aspetos relacionados com as lesões músculo-esqueléticas associadas à prática desportiva das crianças e adolescentes, incluindo os aspetos éticos envolvidos, assim como identificar alguns dos principais fatores de risco e apontar algumas das medidas a adotar para a sua prevenção.

Introduction Patients with schizophreniform disorder(SD) and schizophrenia present similar symptoms, however, SD has a shorter duration, varying between at least 1 month and 6 months. Objectives To describe and analyse Schizophreniform disorder related hospitalizations in a national hospitalization database. Methods We performed a retrospective observational study using a nationwide hospitalization database containing all hospitalizations registered in Portuguese public hospitals from 2008 to 2015. Hospitalizations with a primary diagnosis of schizophreniform diso72.1-der were selected based on International Classification of Diseases version 9, Clinical Modification (ICD-9-CM) code of diagnosis 295.4x. Birth date, sex, residence address, primary and secondary diagnoses, admission date, discharge date, length of stay (LoS), discharge status, and hospital charges were obtained. Comorbidities were analysed using the Charlson Index Score. Independent Sample T tests were performed to assess differences in continuous variables with a normal distribution and Mann-Whitney-U tests when no normal distribution was registered. Results In Portuguese public hospitals, a total of 594 hospitalizations with a primary diagnosis of Schizophreniform disorder were registered during the 8-year study period. Most were associated to the male sex patients, 72.1% (n=428). The mean age at admission was 35.99 years and differed significantly between sexes (males - 34.44; females- 40.19; p<0.001). The median LoS was 17.00 days and the in-hospital mortality was 0.5% (n=3). Only 6.1% (n=36) of the hospitalization episodes had 1 or more registered comorbidities. Conclusions Hospitalizations with a primary diagnosis of Schizophreniform disorder occur more frequently in young male patients. This is the first nationwide study analysing all hospitalization episodes in Portugal. Disclosure No significant relationships.
