ABSTRACT Purpose To evaluate hemostasis of the ovarian arteriovenous complex (OAVC) in relation to surgical time, practicality and feasibility in three ovariohysterectomy (OH) techniques for queens. Methods The experiment was performed on 21 female cats aged between six months and seven years, randomly arranged into three groups in a completely randomized design. Group one was spayed using the conventional three-clamp technique, group two using the OAVC knotting technique, and group three using the ovarian pedicle rotation technique. The student’s t-test and Tukey’s test were used to compare the mean surgical times. Results The conventional technique, which uses thread wires, was more laborious and required longer execution time compared to the other two techniques. The OAVC knotting technique was the fastest and had the least blood loss. Conclusions The use of techniques that do not use synthetic materials for OAVC hemostasis was proven to be appropriate in castration projects, provided that the surgical team has sufficient training.

RESUMO: O presente trabalho teve por objetivo caracterizar as oftalmopatias em cães naturalmente afetados por leishmaniose visceral em Teresina, Piauí. O diagnóstico de leishmaniose foi realizado por exame parasitológico de medula óssea e linfonodos. As principais alterações oftálmicas foram uveíte, conjuntivite, blefarite, ceratite e ceratoconjuntivite seca. Anemia normocítica normocrômica foi a principal alteração hematológica, seguida de trombocitopenia. Em relação às proteínas plasmáticas observou-se hiperproteinemia, hiperglobulinemia e hipoalbuminemia. A histopatologia ocular revelou processo inflamatório moderado constituído por linfócitos, monócitos, neutrófilos e macrófagos. Os resultados da pesquisa apontam para a necessidade de se realizar diagnóstico diferencial para Leishmania sp. em cães que apresentem lesões oftálmicas em regiões endêmicas.

ABSTRACT: This study aimed to characterize ocular diseases in dogs naturally affected by visceral leishmaniasis in Teresina, Piauí State, Brazil. The diagnosis was made using parasitological exams of the bone-marrow and lymph-node samples. The main ophthalmological findings were uveitis, conjunctivitis, blepharitis, keratitis, and keratoconjunctivitis sicca. Normocytic normochromic anemia was the main hematological finding, followed by thrombocytopenia. Plasma proteins were also considered, and hyperproteinemia, hypergammaglobulinemia, and hypoalbuminemia were observed. Ocular histopathological examination revealed mild inflammation involving lymphocytes, monocytes, and macrophages. Results indicate the need to perform a differential diagnosis to rule out or establish the presence of Leishmania sp. in dogs presenting with ophthalmic lesions in endemic regions.

Integrando as pesquisas sobre parasitoses na região do entorno do Parque Nacional Serra da Capivara, Piauí, Brasil, realizadas entre 1999 e 2001, o presente estudo tem como objetivo avaliar a situação epidemiológica da cisticercose humana no Município de João Costa, no Nordeste do Brasil. Foram obtidas informações clínico-epidemiológicas e coletadas amostras de sangue para testes sorológicos imunoenzimáticos (ELISA e Western blot), empregando cisticercos de Taenia crassiceps como antígeno. Na primeira etapa, em 1999, foram investigadas 169 pessoas com história confirmada ou suspeita de infecção/doença pelo complexo teníase-cisticercose, e seus familiares. Na análise, 13,6% das pessoas apresentaram soros reagentes para cisticercose pelo método ELISA. Na segunda etapa, em 2001, foram avaliadas 92 amostras de soro de indivíduos reativos para cisticercose detectados no primeiro momento e seus familiares, sendo que 24,0% das amostras de soro foram reagentes para cisticercose pelo ELISA, e 29,0%, pelo WB. Nessa mesma etapa, realizou-se inquérito coprológico em 701 pessoas, incluindo voluntários. A prevalência de parasitoses intestinais foi de 51,0%, tendo sido observada uma maior prevalência de protozoários (95,0%) em relação aos helmintos (5,0%). Os resultados do estudo indicam o caráter endêmico da cisticercose na área, além da elevada freqüência de protozooses intestinais.

As part of parasitological studies in the area surrounding the Serra da Capivara National Park, Piauí State, Northeast Brazil, from 1999 to 2001, the current study aimed to evaluate the epidemiological profile of human cysticercosis in the Municipality of João Costa. Clinical and epidemiological data were obtained, and blood samples were drawn for immunoenzymatic serological tests (ELISA and Western blot), using Taenia crassiceps as the antigen. The first stage, in 1999, investigated 169 individuals with a confirmed history or suspicion of infection/disease involving the teniasis/cysticercosis complex, along with the family members. Some 13.6% of the individuals were seroreactive for cysticercosis by the ELISA method. The second stage, in 2001, evaluated 92 serum samples of individuals who had been detected as reactive for cysticercosis in the first stage, along with their family members; 24% of the samples were reactive to cysticercosis by ELISA and 29% by Western blot. During this same stage a coprological survey was performed with 701 individuals, including volunteers. Prevalence of intestinal parasites was 51%, with a higher prevalence of protozoans (95%) than helminths (5%). The results indicate the endemicity of cysticercosis in the area, in addition to the high frequency of intestinal protozoan infections.
