“…The latency and interval values observed in this study are in agreement with those obtained in dogs by other authors (Marshall, 1985;Knowles et al, 1988;Haagen et al, 1989;Harcourt et al, 2010) but shorter than those reported in human studies (Anias et al, 2004;Bento et al, 2009).…”

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.

“…7,[12][13][14] Several authors have reported that BAEP responses in neonates and nursing infants are affected by the maturity of the auditory system. 7,12,[15][16][17][18][19] The effect of maturity is even more evident in premature infants; thus, the response pattern in these children differs from those in term neonates. 7,15,16,[19][20][21] Studies on the effects of neural maturity of the hearing system in premature neonates are sparse in the Brazilian literature.…”

Aim:To compare ABR responses in full-term and premature infants; gender and ear were taken into account. Methods:A cross-sectional prospective cohort study was carried out. We evaluated 36 full-term and 30 premature infants that had passed the Transient Otoacoustic Emissions test, had type A tympanometric curves, and had no risk factor for hearing loss besides prematurity. The evaluations were done from the time of hospital discharge to the third month of life, and consisted of a clinical history, acoustic immittance testing and ABR evaluation. Results:The comparison of absolute and interpeak wave I, III and V latencies in right and left ears revealed a statistically significant difference at the interpeak I-III. There was no significant gender differences in the comparison of results. Significant difference in wave I, III and V absolute latencies at 80 dB and in wave V at 60 db and 20 db were observed in a comparison of absolute and interpeak latencies between full-term and premature infants. An inverse correlation was found between age and absolute latencies. Conclusions:The maturity of the auditory system influences ABR responses in infants. To avoid misinterpretation of results, gestational age must be taken into account in the analysis of ABR in pediatric population. Braz J Otorhinolaryngol. 2010;76(6):729-38. ORIGINAL ARTICLE BJORL

“…Thus, the electrophysiological records in the Integrity system were compatible with those of a The time of examination in movement is higher than at rest (p < 0.001), in both ears gold standard equipment available in the market, with respect to the average variable of the absolute latencies of the I, III, and V waves and the interpeak latencies I-III, III-V, and IV. According to the literature (24,25,26) the average values of the latencies of wave I range between 1.50 and 1.68 ms, those of wave III range between 3.50 and 3.80 ms, and those of wave V range between 5.50 and 5.64.…”

Purpose: Recording the evoked auditory brainstem response, in resting conditions and movement for the same individual, using new equipment/ system Integrity and verifying the agreement of these responses when compared to a conventional gold device/system standard in the market. Methods: Thirty normal-hearing adults from both genders, aged 18 to 30 years, were submitted to Auditory Brainstem Response (ABR). Two devices, a device/system Integrity, using bluetooth technology, the conditions of rest and motion and other equipment/conventional system were used to record responses in the same individual. Results: The comparison between the absolute and interpeak latencies observed in conditions of rest and motion, equipment Integrity are similar. The examination times observed in both devices, in the resting are the same. The acquisition time ABR, provided movement is greater than the resting condition, the Integrity equipment. Conclusion: Values were obtained for normal ABR in normal hearing adults in equipment/system Integrity, which are the same for the conditions of the individual at rest and in motion. The latencies in the two devices are equivalent in the resting condition, there was an agreement between the values of latencies, equipment Integrity, on the conditions of rest and motion.Keywords: Evoked potentials, Auditory; Hearing; Brain stem; Electrophysiology; Adult RESUMO Objetivo: Registrar os potenciais evocados auditivos de tronco encefálico nas condições de repouso e movimento, no mesmo indivíduo, utilizando o novo equipamento/sistema Integrity, e verificar a concordância das respostas, quando comparadas a um equipamento/sistema convencional, padrão-ouro no mercado. Métodos: Trinta adultos com audição normal, de ambos os gêneros, entre 18 e 30 anos, foram submetidos ao Potencial Evocado Auditivo de Tronco Encefálico. Para registro das respostas no mesmo indivíduo, foram usados dois equipamentos, um deles (Integrity) com tecnologia bluetooth, nas condições de repouso e movimento e outro, equipamento/sistema convencional, na condição de repouso. Resultados: A comparação entre as latências absolutas e interpicos observada nas condições de repouso e movimento, no equipamento Integrity, foi de equivalência. Os tempos de exame observados nos dois equipamentos, na condição de repouso, foram iguais. O tempo de aquisição do potencial evocado auditivo, na condição de movimento, foi maior que na condição de repouso, no equipamento Integrity. Conclusão: Os valores de referência em adultos ouvintes normais no equipamento Integrity foram os mesmos para as condições de repouso e em movimento. As latências obtidas nos dois equipamentos foram equivalentes na condição repouso. Houve concordância entre os valores das latências no equipamento Integrity, nas condições de repouso e de movimento.
