Brainstem auditory evoked potential testing in Dalmatian dogs in Brazil
The brain stem auditory-evoked potential (BAEP) is an electrophysiologic test that detects and records the electrical activity in the auditory system from cochlea to midbrain, generated after an acoustic stimulus applied to the external ear. The aim of this study is to obtain normative data for BAEP in Dalmatian dogs in order to apply this to the evaluation of deafness and other neurologic disorders. BAEP were recorded from 30 Dalmatian dogs for a normative Brazilian study. Mean latencies for waves I, III, and V were 1.14 (±0.09), 2.62 (±0.10), and 3.46 (±0.14) ms, respectively. Mean inter-peak latencies for I-III, III-V, and I-V intervals were 1.48 (±0.17), 0.84 (±0.12), and 2.31 (±0.18) ms, respectively. Unilateral abnormalities were found in 16.7% of animals and bilateral deafness was seen in one dog. The normative data obtained in this paper is compatible with other published data. As far as we know this is the first report of deafness occurrence in Dalmatian dogs in Brazil

O objetivo deste estudo Ă© obter dados normativos para o BAEP em cĂŁes da raça Dálmata para usá-lo para detecção de surdez e de outras alterações neurolĂłgicas. BAEP foi obtido de 30 cĂŁes da raça Dálmata para um estudo normativo no Brasil. As latĂŞncias mĂ©dias para as ondas I, III e V foram 1,14ms (±0,09); 2,62ms (±0,10) e 3,46ms (±0,14), respectivamente. A mĂ©dia das latĂŞncias dos intervalos I-III, III-V e I-V foi 1,48ms (±0,17); 0,84ms (±0,12) e 2,31ms (±0,18), respectivamente. Alteração unilateral foi observada em 16,7% dos animais, e surdez bilateral foi observada em um cĂŁo. Os dados normativos obtidos neste trabalho sĂŁo compatĂveis com outros dados já publicados. Segundo a revisĂŁo realizada, este Ă© o primeiro relato da ocorrĂŞncia de surdez em cĂŁes da raça Dálmata no Brasil
