“…To test the cochlear sensory function, TEOAEs were recorded. The TEOAEs were classified as normal or abnormal based on the criteria described by Welzl-Muller and Stephan (47). Only with a normal tympanogram do abnormal emissions indicate cochlear dysfunction.…”

ATP8B1 deficiency is caused by autosomal recessive mutations in ATP8B1, which encodes the putative phospatidylserine flippase ATP8B1 (formerly called FIC1). ATP8B1 deficiency is primarily characterized by cholestasis, but extrahepatic symptoms are also found. Because patients sometimes report reduced hearing capability, we investigated the role of ATP8B1 in auditory function. Here we show that ATP8B1/Atp8b1 deficiency, both in patients and in Atp8b1 G308V/G308V mutant mice, causes hearing loss, associated with progressive degeneration of cochlear hair cells. Atp8b1 is specifically localized in the stereocilia of these hair cells. This indicates that the mechanosensory function and integrity of the cochlear hair cells is critically dependent on ATP8B1 activity, possibly through maintaining lipid asymmetry in the cellular membranes of stereocilia.

“…The criterion for a valid CEOAE was a successful probe fit plus a reproducibility (i.e. cross-correlation between two quasi-simultaneously determined average response waveforms) greater than 55% [Welzl-Muller and Stephan, 1994]. In 5 borderline cases (reproducibility 51-55%), the absence or presence was judged visually.…”

Otoacoustic emissions (OAEs) were studied in patients with Ménière’s disease in order to assess their usefulness for distinguishing between different stages of the disease. An accurate classification of Ménière’s patients is expected to allow optimalization of the treatment for each particular stage. Click-evoked and distortion product OAEs were evaluated in both ears for 70 Ménière’s patients. Based on these measurements, Ménière’s patients can be divided into four different categories. In patients with small hearing losses OAEs are found, whereas patients with pure-tone thresholds larger than 60 dB exhibit no OAEs at all. In the intermediate range (30- to 60-dB thresholds) two categories of patients are distinguished: patients with relatively large emissions and patients without measurable emissions. These findings suggest the presence of various stages in the pathophysiological mechanism involved in Ménière’s disease. Additionally, Ménière’s patients with contralateral ears with normal thresholds have significantly smaller emissions than normal-hearing adults. This observation could represent a very early manifestation of bilateral Ménière’s disease, which cannot be detected by other diagnostic methods.

O equipamento portátil (ILO ECOCHECK, AUDX, entre outros) é uma outra alternativa, além dos aparelhos tradicionais (ILO 292, Byologic, Celesta, etc.) para a triagem auditiva em neonatos. Objetivo: Realizamos Emissões Otoacústicas Evocadas Transitórias com os dois equipamentos, em 88 recém-nascidos normais sem risco auditivo para observar as respostas obtidas, procurando determinar, assim, a concordância entre os dois equipamentos. The portable equipment (ILO ECOCHECK -AUDX, among others) is another alternative besides the traditional devices (ILO 292 -BYOLOGIC, CELESTA, etc.) for the auditive selection in newborn children. Aim: We have realized transiently otoacoustics emissions with both devices, in 88 normal newborn children without risk of auditive danger to observe the responses gotten with both, determining, this way, the agreement between both devices. Study design: Clinical prospective. Results: We have noticed that the newborn children who failed in ILO 292 also failed in ILO ECOCHECK; however, not all of them who failed in ILO ECOCHECK failed in ILO 292. We have also noticed that the ones who had failed in ILO ECOCHEK had showed us no response in the first analyzable band of frequency of ILO 292. Conclusion: We have concluded that the portable equipament revealed itself more rigorous in the characterization of the normal exam than the criterion of normaity used in the evalution of the conventional exam.Rev Bras Otorrinolaringol.
