background: participation is an important component in a child’s growth, which is not just affected by child's functional abilities, skills, interests and family culture; but also affected by the physical, social and institutional environment. hearing and visual impairment in children may cause growth delay including cognitive, mobility and communication skills. the aim of this study was to com...

Introduction: Neonatal hypernatremia dehydration (NHD) is a dangerous condition in neonates, which is accompanied by acute complications (renal failure, cerebral edema, and cerebral hemorrhage) and chronic complications (developmental delay). Children begin learning language from birth, and hearing impairment interferes with this process. We assessed the hearing status of infants with hypernatr...

inner ear cells are sensitive to some metabolic and hormonal disorders, but the relation between chronic renal failure (crf), regular dialysis treatment (rdt) and sensorineural hearing loss (snhl) is still a debatable field. the object of this paper was to verify the presence of snhl in patients submitted to hemodialysis with different duration due to crf and in those submitted to conservative ...

Through pure-tone audiometry, we studied the course of hearing recovery in 24 ears of 20 men (ages 18-48 years) who had acute acoustic sensorineural hearing loss (ASHL). All subjects were members of the Japanese Self-Defense Force. The hearing level in 5 ears returned to normal, the hearing level of 13 ears recovered but was not within the normal range, and the hearing level of 6 ears was uncha...

The efficacy of a screening procedure for detecting nonorganic hearing loss using standard audiometric instrumentation was examined. Thirty normal-hearing subjects' responses to continuous and standard and lengthened off-time pulsed tones, using an ascending-descending method, were compared. Subjects were asked to respond to test stimuli in normal-hearing and simulated hearing loss conditions. ...

Timbre is a combination of all auditory object attributes other than pitch, loudness and duration, and is used to distinguish different musical instruments or voices. People with sensorineural hearing loss often have problems with timbre distortion. Even for modern hearing aids it is difficult to provide good audio quality for speech intelligibility while preserving the natural timbre. This not...

Gjb2 and Gjb6, two contiguous genes respectively encoding the gap junction protein connexin26 (Cx26) and connexin 30 (Cx30) display overlapping expression in the inner ear. Both have been linked to the most frequent monogenic hearing impairment, the recessive isolated deafness DFNB1. Although there is robust evidence for the direct involvement of Cx26 in cochlear functions, the contribution of ...
