Estudo clínico de celulite orbitária e pré-septal na infância Objetivo: Estudar retrospectivamente aspectos clínicos e terapêuticos em crianças portadoras de celulite orbitária e pré-septal. Métodos: Foram analisados 52 prontuários de pacientes com idades variando de um mês a doze anos, internados no período compreendido entre 1990 e 1998, com quadro de celulite orbitária ou pré-septal. Resultados: Trauma foi o fator predisponente mais freqüente das celulites orbitárias e pré-septais na infância, seguido pela sinusite e causas não-definidas. As infecções, na grande maioria, tiveram localização pré-septal (94,2%). As hemoculturas, realizadas em 21 pacientes, resultaram em 71% de negatividade, seguido por positividade para S. aureus (19%), H. influenzae (4,7%) e flora mista (4,7%). Todos os pacientes foram tratados e curados com antibioticoterapia utilizando 16 quimioterápicos em 25 diferentes esquemas terapêuticos. A drenagem cirúrgica foi realizada em apenas 7 pacientes. Conclusão: A despeito da falta de uniformidade e diversidade de esquemas terapêuticos empregados nos casos estudados e da falta de avaliação oftalmológica na maioria dos casos, os pacientes foram curados sem complicações. Tal fato indica a necessidade de estudos prospectivos que visem a elaboração de protocolo terapêutico para as celulites da região orbitária na infância, que leve em consideração a relação custo-benefício positiva.
RELATOS DE CASOS
Envolvimento orbital bilateral na doença de Erdheim-Chester -Relato de casoPurpose: To report a case of Erdheim-Chester disease with bilateral orbital involvement and to inform ophthalmologists about this uncommon condition. Methods: Case report. A 41-year-old man presented with proptosis, lid xanthelasmas, disc edema and extraocular muscle restrictions. He was suspected of having a systemic lymphoma and had already been submitted to a retroperitoneal biopsy, however, the diagnosis was still uncertain.
Results:The patient was evaluated by computed tomography and magnetic resonance imaging of the orbit. Orbital pseudotumor was suspected and a biopsy of the orbital lesion initially failed to provide the correct diagnosis which was only made after detailed analysis of the clinical and imaging findings, and review of the histopathologic studies. The systemic diagnosis was made after the orbital diagnosis although the patient had been extensively investigated for more than one year. Conclusions: ErdheimChester disease is a rare idiopathic systemic condition characterized by a xanthogranulomatous process involving retroperitoneum, heart, lungs, bone and other tissues. The condition is often fatal due to renal or cardiovascular complications. Ocular findings are rare but may be very helpful for the diagnosis. Therefore, ophthalmologists should be aware of the clinical manifestations and imaging findings of this rare disease in order to establish an early diagnosis.
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.
