Estudo retrospectivo de exames citológicos realizados em um Hospital Veterinário Escola em um período de cinco anos / Retrospective study on the cytological exams in a Veterinary Technic Hospital in a five year period

Avaliaram-se os resultados de exames citológicos realizados em seis anos e determinou-se o tipo de distúrbio (inflamatório, infeccioso, proliferativo) mais comum. Aspectos epidemiológicos, como espécie, raça, sexo e idade, foram levados em consideração. Foram realizadas 270 avaliações citológicas e destas a prevalência foi de neoplasmas (53%). A espécie canina foi a mais ocorrente, com 92% dos casos. As fêmeas somaram 53% do total. A idade variou de um a 17 anos, sendo o intervalo de seis a 10 anos mais ocorrente (40% dos casos). As neoplasias de células redondas foram as mais prevalentes, seguidas das neoformações mamárias.

The cytological exam is a practical diagnostic aplication which allows the detection of inflammatory, proliferative and infectious disturbances. In the present study, the results of cytological exams during six years were evaluated, determining the most common type of disorder (inflammatory, infectious, proliferative). Epidemiological aspects such as species, breed, sex and age were taken into account. 270 reviews were evaluated and the prevalence was neoplasms (53%). The canine specie was the most observed, with 92% of cases. Females totaled 53%. The age ranged from one to 17 years and the interval of six to 10 years was most observed (40% of cases). The round cell neoplasms were the most prevalent, followed by breast neoformations.

Proteinograma sérico de cães sadios e com linfoma obtido por eletroforese em gel de poliacrilamida (SDS-PAGE) / Serum protein concentrations in healthy dogs and dogs with lymphoma by means of sodium dodecil sulphate-polyacrylamide gel electrophoresis (SDS-PAGE)

Foram avaliadas amostras de soro sanguíneo de 10 cães sadios e de 12 com linfoma, utilizando-se a eletroforese em gel de poliacrilamida contendo dodecil sulfato de sódio. Houve diferença entre as médias dos teores de proteína total de cães sadios, 7,68g/dL±0,46 e de cães com linfoma, 7,93g/dL±2,49. As concentrações de IgA e IgG não foram diferentes entre os grupos. Os teores das proteínas de pesos moleculares 142000, 110000, 52000, 49000, 24000 e 18000 dáltons foram mais elevados em cães com linfoma. Os cães com linfoma apresentaram concentrações mais elevadas de ceruloplasmina, 43,95mg/dL±18,19, e haptoglobina, 554mg/dL±449,51, e menores de albumina, 2908mg/dL±476,67, em comparação aos cães sadios (ceruloplasmina: 3,42mg/dL±7,44; haptoglobina: 94,54mg/dL±59,50 e albumina: 4207mg/dL±206,18). Conclui-se que concentrações séricas mais elevadas de ceruloplasmina e haptoglobina e menores de albumina podem estar associadas ao linfoma em cães.

Blood serum samples of ten healthy dogs and 12 dogs with lymphoma were evaluated by means of sodium dodecil sulphate-polyacrylamide gel electrophoresis. There was difference in total protein concentrations among healthy dogs, 7.68g/dL±0.46 and dogs with lymphoma, 7.93g/dL±2.49 values of immunoglobulins A and G presented no difference between groups. Serum proteins with molecular weights 142,000; 110,000; 52,000; 49,000; 24,000; and 18,000 Daltons presented increased concentrations in dogs with lymphoma. Dogs with lymphoma presented increased ceruloplasmin (43.95mg/dL±18.19) and haptoglobin (554mg/dL±449.51) values and lesser albumin concentration (2,908mg/dL±476.67) when compared to healthy dogs (ceruloplasmin: 3.42mg/dL±7.44; haptoglobin: 94.54mg/dL±59.50, and albumin: 4,207mg/dL±206.18). In conclusion, increased ceruloplasmin and haptoglobin and lesser albumin serum concentrations are possibly related to lymphoma in dogs.

Síndrome de Sézary em cadela / Sézary syndrome in a bitch

The present report describes a case of Sezary syndrome in a canine with lymphadenomegaly, generalized erithroderma, intense pruritus and disseminated cutaneous nodules and plaques. Biopsy samples were taken from cutaneous nodules and plaques and were diagnosed epitheliotropic T cell cutaneous lymphoma by histology and immunohistochemical stain. Bone marrow cytology confirms leukemia. Diagnosis of Sezary syndrome was achieved through clinical, hematological, citopathological, histopathological and immunohistochemical findings. The patient was treated with Madison-Wisconsin chemotherapy protocol, but died after two mouths of treatment
