Audiological manifestations in children and adults with AIDS.

Background: according to the literature, the incidence of hearing impairment in patients with HIV / AIDS might be caused by alterations in external, middle and / or internal ear.

Aim: to characterize and to compare the results of audiological assessment and Auditory Brainstem Response in children and adults with AIDS.

Method: audiological and electrophysiological (Auditory Brainstem Response) assessment of hearing was carried out in 51 children and 22 adults with HIV/AIDS (research groups I and II, respectively) and in 50 healthy children and 25 healthy adults (control groups I and II, respectively).

[Long latency auditory evoked potentials in adults with HIV/Aids].

Background: Long Latency Auditory Evoked Potentials.

Aim: to characterize the Long Latency Auditory Evoked Potentials (LLAEP) in individuals with HIV/AIDS in comparison to a control group.

Method: the research sample was composed by 21 individuals with HIV/AIDS - research group (14 male and 7 female), with ages ranging from 31 to 48 years, and 21 healthy individuals - control group (5 male and 16 female), with ages ranging from 19 to 36 years.

A comparison between hearing and tone burst electrophysiological thresholds.

Unlabelled: Studies have reported compatibility between hearing and electrophysiological thresholds in the auditory brainstem response (ABR) with tone burst stimuli.

Aims: to verify waves I, III, V and their latency times for tone bursts at 500, 1000, 2000 and 4000 Hz and at 80 dB HL, and to compare tone burst electrophysiological thresholds with those obtained from audiological and psychoacoustic evaluations.

Methods: audiological, psychoacoustic and electrophysiological evaluations of 40 male and female normal hearing individuals aged between 18 and 40 years were undertaken.
