This article presents a bibliographical review about the excessive weight of schoolchildren's backpacks and its potential harm to their health. Several reviewed studies consider that the proper backpack load is up to 10% of body mass, being acceptable between 10 and 15%, however, with the potential to cause some damage. The backpack load overloads the spine causing postural changes, pain, dysfunction, and metabolic changes observed at the studied time when it is over 15% of the body weight. It is assumed that there is the future harm with the use of backpacks with loads up to 15% of the body mass. We also observed that re-education involving the correct way to use the backpack with a load reduction is of great value as an initiative to prevent harm, being the simplest and most effective action. Therefore, we identify the need for studies with a focus on the development of possible lesions and improved preventive and treatment approaches.
A síndrome de Axenfeld-Rieger (SAR) é uma doença de origem hereditária com padrão autossômico dominante, com incidência de 1 em 200000 pacientes, caracterizada por distúrbios heterogêneos oculares e sistêmicos. As alterações oculares são geralmente bilaterais e afetam principalmente a íris, a córnea, a linha de Schwalbe e ângulo da câmara. Dentre as manifestações não oculares estão as malformações cardíacas e renais, pele periumbilical redundante, malformações auriculares e alterações hipofisárias. O objetivo do presente trabalho é relatar um caso de SAR de diagnóstico tardio associada a glaucoma, com evolução para dano visual grave, em paciente com diversas alterações oftalmológicas e sistêmicas, ressaltando a importância do reconhecimento precoce da SAR a fim de proporcionar um manejo clínico e cirúrgico adequados, com intuito de preservar a função visual dos pacientes e evitar prognóstico desfavorável. Palavras-chave: Glaucoma secundário, Disgenesia do segmento anterior, Embriotoxon posterior, atrofia iriana, microcornea, anodontia, Síndrome de Axenfeld Rieger.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
