Oftalmomiíase externa / External ophthalmomyiasis

RESUMO O objetivo deste resumo é relatar um caso de portador de oftalmomiíase externa, discorrendo sobre o quadro clínico, os diagnósticos diferenciais e as opções de tratamento. As informações foram obtidas por meio de revisão do prontuário, entrevista com o paciente e registro fotográfico dos métodos diagnósticos e terapêuticos aos quais o paciente foi submetido. Dados foram analisados junto a uma extensa revisão da literatura. O nosso artigo relata um caso de um paciente que foi inicialmente diagnosticado e tratado como celulite pré -septal e após avaliação de especialista em oculoplástica foi realizado o diagnóstico e tratamento adequado para oftalmomiíase. Também revela a importância deste diagnóstico, infrequente nos grandes centros urbanos, seu tratamento e evolução.

ABSTRACT The purpose of this report is to describe a case of external ophthalmomyiasis, discussing the clinical picture, differential diagnoses and treatment options. The information was obtained by means of a review of the medical record, an interview with the patient and a photographic record of the diagnostic and therapeutic methods to which the patient was submitted. Data were analyzed together with an extensive review of the literature. Our article reports a case of a patient who was initially diagnosed and treated for pre-septal cellulitis and after evaluation by a specialist in oculoplastics, the diagnosis and appropriate treatment for ophthalmomyiasis was performed. It also reveals the importance of this diagnosis, infrequent in large urban centers, its treatment and evolution.

[Control of bovine hypodermosis in Switzerland; looking back]. / Die erfolgreiche Bekämpfung der Hypodermose in der Schweiz: Ein Blick zurück.

For many years, hypodermosis control - which started in the 1920's - was unsatisfactory, partly due to a lack of efficacy or a too high toxicity of the available products. An improved control became possible with the introduction (1957) of the organophosphate Metrifonate (Neguvon®, Bayer AG). Subsequent large-scale campaigns according to the Federal Ordinance on epizootic diseases (1967) quite reduced hypodermosis in Switzerland. However, due to a limited use of the product (only young and alpine-grazing cattle were allowed to be treated, administratively indicated maximum dose, side-effects) and its incomplete efficacy, a full control was not possible. The decision to maintain hypodermosis as a "notifiable" disease then allowed further epidemiological studies. In 2000/2001 a concerted action in close cooperation with the cantonal veterinarians allowed a consequent and systematic treatment of all cattle in all endemic areas by the large-scale use of Eprinomectin (Eprinex®, Merial Inc.) for dairy cattle and of Ivermectin (Merial Inc.) as microdose "off-label" for young cattle has led to a rapid and sustainable success.
