Hipertensão situacional em cães dóceis adultos / Situational hypertension in docile adult dogs

A hipertensão arterial sistêmica (HAS) é uma enfermidade silenciosa que pode afetar gatos e cães. Embora bastante descrita em felinos, a "Síndrome do Jaleco Branco", ou hipertensão situacional, é pouco relatada em cães. Assim, este trabalho tem como objetivo mostrar a importância do estresse na aferição da pressão arterial de cães adultos. O estudo foi realizado com 46 cães de ambos os sexos, dóceis, adultos, e aparentemente saudáveis. Após anamnese, exame físico, ambientação e manejo amigável dos animais, mensurou-se a pressão arterial sistólica (PAS) pelo método Doppler no membro torácico. Foram feitas várias aferições para obtenção de média aritmética. Animais com até 160mmHg de PAS, na primeira aferição, foram considerados normotensos (36 cães, correspondente a 78,26%). Para os que tiveram PAS maior ou igual a 160mmHg (dez cães, equivalente a 21,74%), realizou-se um segundo momento de aferição, após 15 a 30 minutos, com os animais em repouso. Assim, seis desses cães apresentaram PAS entre 154mmHg e 200mmHg, sendo, então, um considerado pré-hipertenso e cinco hipertensos, e outros quatro considerados normotensos. Para o animal com pré-hipertensão e para os hipertensos, realizaram-se exames complementares, pelos quais quatro cães foram diagnosticados com doença renal crônica e dois com dislipidemia familiar dos Schnauzers. Dessa forma, pode-se concluir que, dos 46 cães avaliados, 36 apresentaram-se normotensos (78,26%), um pré-hipertenso (2,17%), cinco hipertensos (10,87%) e quatro com hipertensão situacional (8,7%). Portanto, para cães em ambiente hospitalar, é importante realizar um manejo amigável e, quando necessário, mais de um momento de aferição de PAS para evitar diagnósticos errôneos de HAS.

Systemic arterial hypertension (SAH) is a silent disease that can affect cats and dogs. Although well described in felines, "white coat syndrome", or situational hypertension, is little reported in dogs. Thus, this paper aims to show the importance of stress in the measurement of blood pressure from adult dogs. The study was conducted with 46 dogs of both sexes, docile, adults, apparently healthy. After anamnesis, physical examination, ambiance, and friendly management of animals, systolic blood pressure (SBP) was measured by the doppler method in the thoracic limb. Several measurements were made to obtain an arithmetic average. Animals up to 160mmHg of SBP, in the first measurement, were considered normotensive (36 dogs, corresponding to 78.26%). For those with SBP higher than or equal to 160mmHg (10 dogs, equivalent to 21.74%), a second measurement was performed after 15 to 30 minutes, with the animals at rest. Therefore, six of these dogs presented SBP between 154mmHg and 200mmHg (one considered prehypertense and five hypertensives) and four normotensives. For the animal with prehypertension and the hypertensives, complementary examinations were performed, in which four dogs were diagnosed with chronic kidney disease and two with family dyslipidemia of the Schnauzers. Thus, it can be concluded that among the 46 dogs evaluated, there were 36 normotenses (78.26%), a one prehypertense (2.17%), five hypertensives (10.87%), and four with situational hypertension (8.7%). Therefore, regarding dogs in a hospital environment, it is important to perform friendly management and, when necessary, more than one moment of SBP measurement to avoid erroneous diagnoses of SAH.

Leishmaniose visceral em cães / Visceral leishmaniasis in dogs

Background: Canine visceral leishmaniasis (CVL) is a zoonosis of variable clinical presentation, either in systemic orcutaneous form. Clinical signs include anorexia, ophthalmopathies, and chronic kidney disease. In the state of Santa Catarina, the foci are concentrated in the capital and its adjacencies, in the east side of the state. The objective of this studyis to outline the first three reported cases of CVL in the municipality of Curitibanos, since there are no reports to date inthe region of the mountainous plateau, in the middle west of Santa Catarina.Cases: All dogs were treated at the Veterinary Clinic School of the Federal University of Santa Catarina, Campus Curitibanos. The animals, two males and one female, belonged to the same tutor, resided in Curitibanos, and were attendedbetween 2016 and 2020. In the first case, attended in 2016, the complaint was of eye and skin changes about three monthsago. The animal lived in an urban environment and came from Uruguaiana, Rio Grande do Sul. On physical examination,the animal presented skin peeling, wet and crusty lesions, bloody discharge in the ears and nasal hyperkeratosis, as wellas signs suggestive of uveitis. In this case, euthanasia was carried out. The second case had complaints of respiratory, eyechanges, hyporexia, and polydipsia. The dog was prostrate, dehydrated, with lymphadenomegaly and respiratory disorders, compatible with bacterial pneumonia. Bilateral corneal edema confirmed uveitis. Upon return, the animal remaineddehydrated with enlarged lymph nodes. In the aspiration of the lymph nodes, suggestive forms of Leishmania sp. wereobserved. The recommended confirmatory tests were performed, leading to a definitive diagnosis of CVL. The patientwas treated with miltefosine, but later died. The third case was attended for general evaluation after a positive diagnosisfor CVL during an epidemiological survey of the second case. The animal was alert, tachycardic, and tachypneic with...(AU)
