Résumé
A dengue é a infecção viral transmitida por mosquito mais frequente no planeta. No Brasil a incidência vem aumentando em sucessivas epidemias, com uma proporção crescente de casos graves. A qualidade da assistência prestada influencia diretamente o prognóstico da doença. Estas recomendações apresentam o manejo das formas graves de dengue, incluindo o reconhecimento de sinais de alerta, o tratamento visando o pronto re-estabelecimento da euvolemia e a avaliação e cuidado das potenciais complicações, no intuito de reduzir a morbi-mortalidade de crianças e adultos infectados.
Dengue is the most common vector-borne viral infection worldwide. In Brazil, the incidence has increased with successive epidemics, and an increasing proportion of patients present with severe forms of the disease. The prognosis for these patients is directly influenced by the quality of medical care. These guidelines present the management of the severe forms of dengue, including the recognition of warning signs, the treatment for prompt re-establishment of euvolemia and the evaluation and appropriate care of potential complications, thus reducing morbidity and mortality of infected children and adults.
Résumé
Cutaneous manifestations in disseminated strongyloidiasis are infrequent but should raise the suspicion for its diagnosis. We retrospectively evaluated the charts of six patients with cancer and a proven diagnosis of disseminated strongyloidiasis. All patients had received prophylaxis with albendazole before starting antineoplastic therapy, which included high-dose steroids. They presented with septic shock, acute respiratory failure and characteristic purpuric periumbilical skin lesions. Strongyloides larvae were identified in tracheal aspirates (n=5), gastric aspirates (n=4), lung (n=2) and skin biopsies (n=2). All patients died despite antihelminthic therapy and intensive care support.
