Caracterizaram-se as agressões por cães, o perfil das vítimas e dos agressores e as circunstâncias desses acidentes. Calculou-se a amostra aleatória a partir de 20 mil notificações/ano de agressões por cães e realizaram-se 594 entrevistas telefônicas. A maior frequência de agressões ocorreu no sexo masculino, faixa etária de cinco a 14 anos. Lesões leves representaram 80,4%. As profundas (19,1%) ocorreram por cães de porte médio seguidas pelos de grande porte. A maioria dos cães era macho adulto, porte médio. Dos entrevistados, 52,5% desconheciam a condição reprodutiva; 41,0% dos cães não eram esterilizados e 6,4% eram esterilizados. Cães sem raça definida (SRD) provocaram 48,4% dos acidentes, e 57,6% das agressões ocorreram em locais privados. Em 56,2% das agressões, as vítimas eram moradoras do imóvel ou pessoas conhecidas. Com animais não conhecidos a agressão mais frequente ocorreu na rua, 30,8%, e 67,5% dos donos permaneceram com os animais. As agressões foram resultantes da interação homem-cão e devem ser estudadas para se identificarem os possíveis comportamentos que desencadeiam a agressão pelo animal.

This study aimed to characterize aggression by dogs, the profile of victims, and perpetrators and circumstances of these accidents. Understanding the interaction between victims and aggressive dogs contributes to preventing aggression. The random sample from 20.000 reports / year of attacks by dogs was calculated and 594 telephone interviews were conducted. The highest frequency of assaults occurred in males from 5 to 14 years of age. Non-severe injuries represented 80.4%. Deep lesions (19.1%) were caused by medium and large dogs. Most dogs were medium size adult males. Of the respondents, 52.5% were unaware of the reproductive condition, 41.0% of dogs were not sterilized and 6.4% were sterilized. Dogs without defined race caused 48.4% of accidents and 57.6% of assaults occurred in private places. In 56.2% assault victims were residents of the property or known people. Aggressions from unknown animals were more frequent on the street (30.8%). 67.5% remained with the animals' owners. The attacks were the result of interaction between man and dog and should be studied to identify which human and canine behaviors can trigger accidents, to understand how the interaction occurs in different situations whithin the same household, with acquaintances, on the street, and with unknown animals. Educational approaches detailing risks and prevention methods are essential.

Relata-se um caso de esporotricose em um cão da raça Boxer, macho, com seis anos, encaminhado para uma consulta por causa de massa na região nasal e de dispneia. Após o exame físico, o animal foi internado para a realização de citologia, histologia e radiografia. Nos exames citológico e radiográfico, não foram constatadas alterações que justificassem a massa e a dispneia. Na histologia, observou-se a presença de um granuloma contendo dois esporos de Sporothrix schenckii. Foi realizado tratamento com itraconazol 5mg/kg BID por 60 dias. Após esse período, a massa desapareceu e a respiração do animal melhorou, tendo sido recomendada a manutenção da terapia por mais 30 dias, para evitar recidiva.

A case of canine sporotrichosis was reported in a six-year-old male Boxer, referred to a veterinary hospital because of a mass in the region of the nose and dyspnea. After physical examination, the animal was submitted to cytological, histological, and radiographic exams. The cytological and radiographic exams showed no alterations that could justify the mass and the dyspnea. The histological exam showed the presence of a granuloma with two Sporothrix schenckii spores. The dog was treated with itraconazol 5mg/kg BID during 60 days. After this period, the mass disappeared and breathing improved. The therapy was maintained for 30 other days to avoid relapse.

Antimoniais pentavalentes são importantes no tratamento da leishmaniose. Seus efeitos mais graves que têm sido relatados são o aumento do nível de enzimas hepáticas e anormalidades eletrocardiográficas. Nefrotoxicidade tem sido raramente relatada. Nós relatamos um caso de leishmaniose cutânea generalizada, envolvendo um paciente masculino de 50 anos de idade, que foi submetido ao tratamento com Glucantime. Ele desenvolveu insuficiência renal devido a necrose tubular aguda e depois veio a óbito; após receber um total de 53 ampolas de Glucantime. O tratamento com o Glucantime foi o responsável pela necrose tubular aguda diagnosticada em nosso caso.

Background: Pentavalent antimonials have became of basic importance for the treatment of leishmaniasis. Their most severe side effects have been reported to be increased hepatic enzyme levels and electrocardiographic abnormalities. Nephrotoxicity has been rarely related. Observations: We report a case of generalized cutaneous leishmaniasis involving a 50-year old male patient who was submitted to treatment with meglumine antimoniate (Glucantime). He developed acute renal failure (ARF) due to acute tubular necrosis (ATN), followed by death after receiving a total of 53 ampoules of Glucantime. Conclusions: The treatment with Glucantime was responsible by ARF diagnosed in this patient. The previous urine osmolarity and serum creatinine levels were normal and the autopsy showed ATN. It should be pointed out if ARF may also be explained by massive deposits of immunocomplexes by leishmania antibodies and antigens due to the antigenic break by the antimonial compound, since our patient presented countless lesions covering the entire tegument, similar to the Hexheimer phenomenon, but at the autopsy no glomerular alterations were seen.
