RESUMO

A habronemose é uma doença parasitária comum em equídeos no mundo todo. É causada por parasitas do gênero Habronema muscae, Habronema majus ou microstoma e Draschia megastoma, tendo como vetor a mosca doméstica (Musca doméstica) e a mosca do estábulo (Stomoxys calcitrans). A apresentação clínica desta afecção se dá na maioria das vezes sobre a forma cutânea, conjuntival e gástrica, sendo raros os casos das formas nasal, pulmonar e em tecido subcutâneo. As regiões acometidas são, na maioria das vezes, a porção distal dos membros, comissuras labiais, canto medial dos olhos, cavidade nasal, prepúcio e genitália externa, manifestando-se na forma de lesões cutâneas em sua maioria. Esta obra objetivou apresentar um caso de habronemose localizado no tecido subcutâneo prepucial, com ausência de lesão cutânea, diagnosticado através do exame histopatológico.

Habronemiasis is a common parasitic disease of equids worldwide. Is caused by parasites of the genus Habronema muscae, Habronema majus or microstoma and Draschia megastoma, having as vector is the domestic flies (Musca doméstica) and stable flies (Stomoxys calcitrans). The clinical presentation of this condition occurs most of ten on the cutaneous, conjunctival and gastricforms, with rare cases of nasal, pulmonary and subcutaneous tissue. The affected regions are often distinct from the limbs, labial commissures, medial corner of the eyes, nasal cavity, fore skin and external genitalia, presentation of cutaneous exercises in most cases.This paper aims to present a case of habronemosis located in the subcutaneous preputial tissue, with absence of cutaneous lesion and diagnosed through histopathological examination.

RESUMO

Canine visceral leishmaniasis (LVC) is a disease caused by protozoans of the genus Leishmania, patients affected can present a diversity of clinical symptoms, where the main are: slimming, alopecia, Onychogryphosis and dermatitis. However unconventional signs may be linked to this disease. In this sense the purpose of this work is to report a case of LVC with unconventional signs of the disease. The occurs with a Yorkshire dog that was attended with complaint of pruritus and formation of nodules in the flank region, initially the clinical suspicion was of allergic reaction with fungal dermatitis. After the completion of the complementary exams (Cytopathological, blood count, ALT dosages, creatinine and skin scraping for direct examination) was diagnosed LVC from the observation of Amastigota in Cytopathological. With this result we emphasize the attention to the clinical demonstrations in LVC and the importance of complementary exams such as cytology to quick and accurate diagnostics.

RESUMO

Background: Leyomiosarcomas are uncommon malignant smooth muscle tumors of hollow organs. Bovine leyomiosarcomas have been described in several sites, but smooth muscle tumors that arise from the skin are rare in domestic animals. These neoplasms may show variable histologic features depending on their grade of differentiation; therefore, diagnostic tools as special stain, electron microscopy and immunohistochemistry are essential for the definitive diagnosis. Due to the lack of reports of skin leyomiosarcomas in cattle, we described the occurrence of a leyomiosarcoma in the skin and subcutaneous tissue of a Nellore cow. Case: A 10-year-old Zebu Nellore cow was admitted at the Veterinary Diagnosis Center (CEDIVET) of Pará Federal University (UFPA), Brazil, to investigate a tumor on the hip. At clinical examination the cow showed a decreased appetite and weight loss. Due to the bad prognosis the veterinarian recommended euthanasia. Representative tissue samples were submitted for histopathological and immunohistochemistry evaluation at the Department of Pathology of the Federal Rural University of Rio de Janeiro (UFRRJ). The slides were stained by Hematoxylin and Eosin (HE), Massons trichrome and Van Gieson stains and submitted for immunohistochemistry with primary antibodies vimentin, troponin C, smooth muscle alpha actin and desmin. Grossly, the tumor appeared as a multilobular, ulcerated and firm 30 cm diameter mass with black and hemorrhagic areas on the surface. The mass was scattered throughout the subcutaneous tissue and infiltrated the adjacent muscle. On light microscopy, the neoplasm consisted of a non-encapsulated proliferation into the derma, composed of highly pleomorphic spindle to round cells arranged in broad interlacing fascicles and small islands. Metastatic lesions were found in the lungs and local lymph nodes. Massons trichrome stain revealed collagen production and Van Gieson stains was inconsistent...(AU)

RESUMO

No município de Pelotas/RS é comum a utilização de equinos para realizar coleta de resíduos recicláveis ou realização de pequenos fretes, e estima-se que aproximadamente 1500 famílias dependam do cavalo como fonte de renda. E com a finalidade de dar suporte a estas famílias existe o projeto de extensão realizado junto ao loteamento Ceval, o Ambulatório Veterinário do Hospital de Clínicas Veterinária da Universidade Federal de Pelotas(HCV-UFPel) que busca levar aos carroceiros do município de Pelotas/RS, um auxílio para melhor desenvolver a atividade, com enfoque na saúde e bem-estar dos equinos. Foram atendidos 456 equinos no ambulatório veterinário do HCV-UFPel, sendo que 64,69% (295/456) machos e 35,31 % (161/456) fêmeas, 20,18% (92/456) jovens (até cinco anos de idade) e 79,82% (364/456) adultos (com seis anos ou mais), 98,86% (451/456) animais sem raça definida, 0,25% (1/456) da raça Crioula e 0,88% (4/456) Pôneis, Durante o período avaliado foram realizados 792 atendimentos, sendo 27,15% (215/792) retornos e 26,01% (206/792) casos de revisão. Relacionado aos sistemas orgânicos, 14,04% (127/792) com alterações clínicas musculoesqueléticas, 16,04% (113/792) do sistema tegumentar,5,68% (45/792) problemas gastrointestinais, 5,56% (44/792) distúrbios do sistema respiratório, 3,91% (31/792)alterações gênito urinárias, 1,01% (8/792) com enfermidades oftálmicas e 0,38% (3/792) com alterações neurológicas.As principais alterações encontradas nos cavalos de carroça da cidade de Pelotas/RS no período de 2014 e 2015 foram relacionadas ao sistema musculoesquelético, seguido do sistema tegumentar, demonstrando a necessidade de mais orientações aos carroceiros sobre manejo de equinos. O elevado número de animais que retornam para atendimento evidencia a importância do trabalho realizado junto a esses proprietários, que capacita para que ocorra o manejo apropriado, visando manter a saúde e o bem-estar dos equinos.

RESUMO

The present study demonstrated the effects of the arthropod growth regulator, fluazuron (Acatak®), in the formation of the integument and digestive processes of Rhipicephalus sanguineus nymphs fed on rabbits treated with different doses of this chemical acaricide. For this, three different doses of fluazuron (20, 40, or 80 mg/kg) were applied "pour on" to the hosts (groups II, III, and IV), as well as distilled water to the control group. On the first day after treatment (24 h), the hosts were artificially infested with R. sanguineus nymphs. After full engorgement (7 days), the nymphs were removed, placed on labeled Petri dishes, and kept in biochemical oxygen demand incubator for 7 days. The engorged nymphs were then taken for morphological, histochemical, and histological analyses. The results showed the occurrence of cytological, morphohistological, and histochemical alterations in the integument and midgut of nymphs from all the different treated groups. These alterations occurred at cuticular level in the subdivisions of the cuticle, related to the size of the digestive cells, amount of accumulated blood elements, and digestive residues, as well as the presence of vacuoles in the cytoplasm of the digestive cells. Thus, this study demonstrated that fluazuron acts on the integument and midgut cells of R. sanguineus nymphs fed on treated rabbits and pointed out the possibility of the use of this chemical-which is more specific, less toxic, and less harmful to the environment and nontarget organisms-in the control of R. sanguineus, at least in the nymphal stage of its biological cycle.

RESUMO

The present paper is a review of articles on the onset of subepidermal blisters in neoformed integuments. Considering the discrepancy between the literature data and our clinical experience concerning spontaneous onset of subepidermal blisters in neoformed integuments, we decided to conduct an extensive review of the literature. The main finding arising from it was the lack of characterization of the neoformed integument where the blisters were formed. These were normally referred to only by clinical descriptions such as "spontaneously healed burn", "grafted site", "donor site", "epidermal graft". Anatomical and clinical pathology aspects such as the formation mechanism of these integuments and the respective tissues that comprise them were not considered. We concluded that by adopting more precise criteria to classify neoformed integuments we would realize that split thickness grafts are not susceptible to blister formation.
