Bacterial urinary tract infections (UTI) are among the most frequent infectious diseases of small animals. Although antimicrobial therapy is recommended for treating bacterial UTIs, the current consensus is that treatment may not be necessary for asymptomatic animals. The aim of this study was to evaluate the diagnostic ability of urinalysis to detect bacteriuria and to compare it with urine culture (gold standard method) to assess the risk of false-positive results. A retrospective study was conducted from January 2016 to July 2019 and urine samples of 119 dogs were analyzed. Diagnostic validation was performed for urinalysis, based on the morphological classification and intensity of bacteriuria. Agreement between the results was assessed using the kappa (k) index. When the presence of cocci was used as a diagnostic criterion to suggest bacteriuria, it was observed that the agreement (k = -0.006) was lower than that expected by chance. However, a poor agreement (k = 0.22) was also found for bacilli during urinalysis (k = 0.23). A significant degree of agreement was observed in cases with high intensity of bacteriuria. Therefore, urine culture must be performed for conclusive evidence of bacteriuria to avoid false-positive results during urinalysis.

Os glicosímetros (GT) são estratégia importante para mensuração da glicemia. Devem estar dentro das especificações da ISO 15197:2013 e avaliados pela análise da grade de erros. Objetivou-se avaliar a acurácia de dois glicosímetros veterinários (GT1 e GT2), pela comparação dos valores de glicemia mensurados em sangue capilar, com aqueles fornecidos por métodos laboratoriais de referência em amostras plasmáticas, transformadas ou não em valores de plasma equivalente. Na avaliação de GT1 em amostras de sangue capilar e o método laboratorial hexoquinase obtiveram-se média das diferenças de 25,90 mg/dL e 26 % das amostras recaíram sobre os limites propostos pela ISO15197: 2013. A comparação de GT1 aos valores de glicemia estimados para plasma equivalente, mostrou média de diferenças de 10,89 mg/dL e 99 % das amostras atenderam aos limites pretendidos. Comparações avaliação de GT2 e o método laboratorial glicose oxidase em amostras de sangue total capilar, a média das diferenças foi 10,58 mg/dL e 22 % das amostras atenderam aos intervalos propostos pela ISO15197: 2013; quando avaliado pela glicemia estimada para plasma equivalente, a média das diferenças foi de 9,7029 mg/dL e 99% das amostras atenderam aos limites. Quando avaliados pela grade de erros de erros, 87% das amostras avaliadas por GT1 recaíram sobre as zonas de erros A e B e aquelas avaliadas por GT2 apresentaram 86% das amostras sobre tais zonas. Os glicosímetros avaliados não apresentaram a acurácia para mensuração da glicemia capilar conforme os padrões expostos pela normativa ISO 15197:2013.

They must be within the specifications of ISO 15197: 2013 and evaluated by analysis of the error grid. The objective of this study was to evaluate the accuracy of two veterinary glucometers (GT1 and GT2) by comparing the blood glucose values measured in capillary blood with those provided by reference laboratory method in plasma samples, transformed or not at equivalent plasma values. In the evaluation of GT1 in capillary blood samples and the hexokinase laboratory method, the mean differences were 25.90 mg / dL and 26% of the samples fell within the limits proposed by ISO 15197: 2013. The comparison of GT1 to the estimated plasma glucose values showed a mean difference of 10.89 mg / dL and 99% of the samples were in the desired limits. Comparisons of GT2 and laboratory glucose oxidase in capillary blood samples, mean differences were 10.58 mg / dL and 22% of the samples met the ranges proposed by ISO; 15197: 2013. When evaluated by the estimated plasma glucose, the mean differences were 9.7029 mg / dL and 99% of the samples met the limits. When evaluated by the error grid, 87% of the samples evaluated by GT1 fell on the zones of errors A and B and those evaluated by GT2 presented 86% of the samples on such zones. The glucometers evaluated did not present the accuracy to measure capillary ...

Black hair follicular dysplasia (BHFD) is a rare genetic disease in dogs. A black and white female Brazilian Terrier (one year and three months old) was referred with a history of progressive hair loss only in black hair areas. Following anamnesis, clinical examination, trichographic analysis of hairs and histopathological examination of skin fragments, the animal was diagnosed with BHFD. This report describes for the first time a case of BHFD in a pure bred Brazilian Terrier.
