    No Amazonas, o acidente ofídico é um problema de saúde pública pouco conhecido. Por este motivo, foi realizado um estudo descritivo dos acidentes ofídicos atendidos nas Unidades de Saúde de 34 municípios, um distrito e dois pelotões de fronteira do Estado do Amazonas. As características mais comuns encontradas dentre os pacientes foram: agricultor (50,4%), do sexo masculino (81,3%), em idade produtiva (72,1%), picado no membro inferior (88,5%), por jararaca (48,6%) ou surucucu (46,8%), na zona rural de seu município (70,2%) e que só recebeu atendimento médico em tempo superior a seis horas, após acidente (57,3%). As manifestações locais mais freqüentes foram: edema (76,9%), dor (68,7%), eritema (10,2%) e hemorragia (9,3%). Hemorragia (18,8%) foi a manifestação sistêmica mais freqüente. O antiveneno foi administrado em apenas 65,9% dos pacientes. A via mais utilizada foi a endovenosa (52,3%), sendo relevante o uso de vias não mais recomendadas (47,7%). O antiveneno administrado, na maioria dos pacientes, foi o antibotrópico (66,7%). As complicações mais freqüentes foram abcesso (13,7%), necrose (12,3%), infecção secundária (8,3%), insuficiência renal (2,5%) e gangrena (2,5%). Os procedimentos médicos mais usados para o tratamento das complicações foram: drenagem (52,6%), debridamento (28,9%), amputação (10,5%), limpeza cirúrgica (5,3%) e diálise peritoneal (2,6%). A letalidade foi de 1%.<br>In the State of Amazonas, accidents with snakes are a public health problem. For this reasons, the objective of this work was to carry out a descriptive study of the snake accidents attended in the health units of 34 municipalities, one district and two border platoons in the State of Amazonas. The characteristics most commonly observed among those involved in snake accidents were: farmers (50.4%), male (81.3%), belonging to the working age-group (72.1%), bitten on an upper limb (88.5%) by a "jararaca" (48.6%) or a "surucucu" (46.8%) in the rural part of the municipality (70.2%). The local signs and symptoms most frequently observed in those who received medical care more than 6 hours after the accident (57.3%) were edema (76.9%), pain (68.7%), erithema (10.2%) and hemorrhage (9.3%). The systemic manifestation most frequently observed was hemorrhage (18.8%). Serotherapy was administered in only 65.9% of patients, the intravenous route being the route most commonly used to administer the antivenin (52.3%), while other non- recommended routes were widely used. In the majority of patients the antivenin given was antibotropic. The most frequent complications were: abscess 13.7%, necrosis 12.3%, secondary infection 8.3%, renal insufficiency 2.5% and gangrene 2.5%. The medical procedures most used in the treatment of these complications were drainage 52.6%, debridement 28.9%, amputation 10.5%, surgical cleaning 5.3% and peritoneal dialysis 2.6%. The fatality rate was 1%

This study investigated the associations between clinical features, fungal load, coinfections, histological skin changes, and response to itraconazole in cats with sporotrichosis caused by S. brasiliensis. Fifty-two cats with skin lesions and a definitive diagnosis of sporotrichosis were treated with itraconazole for a maximum period of 36 weeks. The animals were submitted to clinical examination and two subsequent collections of samples from the same skin lesion for fungal diagnosis and histopathology, as well as serology for feline immunodeficiency (FIV) and leukaemia (FeLV) viruses. Thirty-seven (71%) cats were clinically cured. Nasal mucosa lesions and respiratory signs were associated with treatment failure. Cats coinfected with FIV/FeLV (n = 12) had a lower neutrophil count in the lesion. A high fungal load in skin lesions was linked to young age and treatment failure, as well as to a longer time of wound healing, poorly formed granulomas and fewer neutrophils, macrophages and lymphocytes in these lesions. These results indicate that itraconazole is effective, but nasal mucosal involvement, respiratory signs and high fungal loads in skin lesions are predictors of treatment failure that will assist in the development of better treatment protocols for cats
