Resumo Objetivo Compilar as informações mais atuais referentes às infecções ostoarticulares em pediatria, inclusive perfil epidemiológico e microbiológico, diagnóstico e tratamento. Fonte dos dados Feita revisão não sistemática nos mecanismos de busca Pubmed, Scielo, Lilacs e Google Scholar, com as palavras-chave bone and joint infection, children, pediatric, osteomyelitis, septic arthritis e espondylodiscitis nos últimos 10 anos. Os artigos mais relevantes foram selecionados pelos autores para compor a base de dados. Síntese dos dados As infecções osteoarticulares ainda são causa importante de morbidade na pediatria. A sua principal etiologia é o Staphylococcus aureus, porém há um aumento na detecção de Kingella kingae, especialmente através de métodos moleculares. A identificação microbiológica possibilita direcionamento de tratamento, enquanto que as provas de atividade inflamatória auxiliam no acompanhamento do tratamento. Exames de imagem são especialmente úteis no diagnóstico inicial das infecções. O tratamento empírico deve incluir cobertura para os principais microrganismos, de acordo com a faixa etária e as condições clínicas do paciente, considerando o perfil de resistência local. Procedimentos cirúrgicos podem ser indicados para diagnóstico, controle do foco e preservação da função. As complicações agudas incluem sepse, trombose venosa profunda e embolia pulmonar. Óbitos são raros. As complicações tardias são incomuns, mas podem levar a deformidades que comprometem o desenvolvimento motor. Conclusão O diagnóstico correto e precoce, com pronta instituição de terapia antimicrobiana adequada e controle do foco, quando indicado, é fundamental para um melhor prognóstico.

Abstract Objective To collect the most up-to-date information regarding pediatric osteoarticular infections, including the epidemiological and microbiological profiles, diagnosis, and treatment. Source of data A non-systematic review was performed on the search engines PubMed, SciELO, LILACS, and Google Scholar, using the keywords “bone and joint infection”, “children”, “pediatric”, “osteomyelitis”, “septic arthritis” and “spondylodiscitis” over the last ten years. The most relevant articles were selected by the authors to constitute the database. Synthesis of data Osteoarticular infections are still a major cause of morbidity in pediatrics. Their main etiology is Staphylococcus aureus, but there has been an increase in the detection of Kingella kingae, especially through molecular methods. Microbiological identification allows treatment direction, while evidence of inflammatory activity assists in treatment follow-up. Imaging tests are especially useful in the initial diagnosis of infections. Empirical treatment should include coverage for the main microorganisms according to the age and clinical conditions of the patient, while considering the local resistance profile. Surgical procedures can be indicated for diagnosis, focus control, and function preservation. Acute complications include sepsis, deep venous thrombosis, and pulmonary embolism. Deaths are rare. Late complications are uncommon but may lead to deformities that compromise motor development. Conclusion A correct and early diagnosis, prompt implementation of adequate antimicrobial therapy, and focus control, when indicated, are critical to a better prognosis.

Abstract Hepatopulmonary hydatidosis in young children is a rare and atypical presentation of Echinococcus granulosus infection. We report the first case of cystic echinococcosis caused by a microvariant of E. granulosus sensu stricto. Chemotherapy and systemic corticoids were administered before curative surgery was performed. Recurrence was not observed for more than 24 months of follow-up.
