History Of

A 9 yr old male castrated Australian shepherd mixed-breed dog with a 3 mo history of intermittent unilateral epistaxis was diagnosed with Pseudallescheria boydii species complex fungal rhinitis and sinusitis. This fungal organism is a rare cause of disease in dogs and an emerging human pathogen. The dog was successfully treated with topical clotrimazole.

Fusarium species are among the most commonly isolated causes of fungal keratitis. Most species of the genus Fusarium belong to Fusarium solani species complex (FSSC). Fusarium lichenicola, a member of the FSSC complex, is a well-established plant and human pathogen. However, reports of fungal keratitis due to Fusarium lichenicola have not been frequently reported. To the best of our knowledge, only twelve cases of Fusarium lichenicola keratitis have been reported in the past fifty years. Clinical cases of Fusarium lichenicola may have most likely been misidentified because of the lack of clinical and microbiological suspicion, as well as inadequate diagnostic facilities in many tropical countries where the burden of the disease may be the highest. We report a case of fungal keratitis caused by Fusarium lichenicola and present a global review of the literature of all cases of fungal keratitis caused by this potentially blinding fungus.

Resumo Febre maculosa é uma doença infecciosa caracterizada por febre, com formas leves e atípicas até formas graves, e, quando não tratada adequadamente, pode apresentar taxa de letalidade de 85%. Causada pela Rickettsia rickettsii, é transmitida por meio da saliva de carrapato. No Brasil, o vetor mais importante é o Amblyomma cajennense. Discute-se o número de óbitos por Rickettsia no Brasil, projetando a necessidade de ampliação e disseminação do conhecimento sobre a possibilidade de ocorrência da febre maculosa brasileira (FMB), além de debater sintomas, diagnóstico diferencial e dados epidemiológicos. A metodologia consistiu na identificação dos óbitos por Rickettsia no Brasil entre 2005-2010, utilizando-se o Sistema de Informação sobre Mortalidade (SIM). Foram estudados 75 casos. Observou-se taxa de letalidade de 24,8% e uma concentração de óbitos nas regiões Sudeste e Sul do país. Os resultados obtidos contribuem para a sensibilização dos profissionais sobre a necessidade de união dos dados clínicos, epidemiológicos e laboratoriais, facilitando o reconhecimento da doença e o tratamento precoce.
