Speech perception in patients submitted to cochlear reimplantation.

Purpose: To analyze the performance of auditory speech perception (PF) after cochlear implant (CI) replacement surgery and associations with age, times of use of the first CI, deprivation, recovery and use of the second device.

Methods: The retrospective study analyzed the medical records of 68 participants reimplanted from 1990 to 2016, and evaluated with PF performance tests, considering as a reference, the greater auditory capacity identified during the use of the first CI. Also analyzed were: Etiology of hearing loss; the reasons for the reimplantation; device brands; age range; sex; affected ear; age at first implant; time of use of the first CI, deprivation, recovery and use of the second device.

Analysis of aided thresholds in children who have undergone cochlear reimplantation: a ten-year follow-up.

Purpose: To characterize hearing thresholds at frequencies of 500, 1000, 2000 and 4000 Hz in children undergoing reimplantation with a follow-up of at least 10 years.

Methods: Retrospective review of medical records of children who underwent reimplantation surgery for at least 10 years. The auditory thresholds obtained in free-field pure tone audiometry with the cochlear implant were evaluated at frequencies of 500, 1000, 2000 and 4000 Hz at four different times: 1 (before failure), 2 (activation), 3 (five years after reimplantation) and 4 (ten years after reimplantation, regardless of the time of use of the 2nd CI) in patients with a follow-up of at least 10 years.

Effects of Sequential Bilateral Cochlear Implantation in Children: Evidence from Speech-Evoked Cortical Potentials and Tests of Speech Perception.

Introduction: Benefits of bilateral cochlear implants (CI) may be compromised by delays to implantation of either ear. This study aimed to evaluate the effects of sequential bilateral CI use in children who received their first CI at young ages, using a clinical set-up.

Methods: One-channel cortical auditory evoked potentials and speech perception in quiet and noise were evoked at repeated times (0, 3, 6, 12 months of bilateral CI use) by unilateral and bilateral stimulation in 28 children with early-onset deafness.

Nursing training program in children's hearing health: a proposal for interactive tele-education.

Objective: To verify the effectiveness of a nursing training program in the area of children's hearing health using interactive tele-education.

Methods: Interrupted time series with non-random control group pre-test/ post-test. A cohort of 41 nurses, with no previous formal training in hearing health.

Early exposure to environment sounds and the development of cortical auditory evoked potentials of preterm infants during the first 3 months of life.

Objective: Preterm infants are exposed earlier than their term counterparts to unattenuated sounds from the external environment during the sensitive period of the organization of the auditory cortical circuitry. In the current study, we investigate the effect of preterm birth on the course of development of auditory cortical areas by evaluating how gestational age (GA) correlates with the latency of the P1 component of the cortical auditory evoked potential (CAEP) of two experimental groups measured at 1 or 3 months of age.

Results: Our sample consisted of 23 infants delivered at GA ranging from 31.

Community health worker training for infant hearing health: effectiveness of distance learning.

Objective: The purpose of this study was to evaluate the effectiveness of a distance training program in infant hearing health to community health workers (CHWs).

Design: Pre- and post- tests were administered to two groups of subjects following the use of an interactive CD-ROM for tele-educational training.

Study Sample: Two groups of subjects were used: Group I (GI) consisted of 43 CHWs who had previously participated in at least one training activity involving hearing health, and Group II (GII) were 47 CHWs who had received no prior training in hearing health.

Polarity stimulation effects on brainstem auditory evoked potentials.

Unlabelled: Brainstem Auditory Evoked Potentials are considered exogenous potentials, that is, the responses obtained are highly dependent upon the characteristic of the stimulus used to evoke them.

Aim: To investigate the influence of the click stimulus polarity in the study of Brainstem Evoked Response Audiometry (BERA) at different intensities, using insertion-canal earphones.

Type Of Study: Clinical.

Training proposal for community health agents in hearing health.

Background: training of community health agents in hearing health.

Aim: to verify the effectiveness of a training program regarding the hearing health of children for Community Health Agents of a Family Health Program.

Method: research sample consisted of two groups: Group A, constituted by 31 community health agents, from Bauru, SP, and Group B, constituted by 75 community health agents, from Sorocaba, SP.

[Bone conduction auditory brainstem responses in normal hearing individuals].

Background: bone conduction auditory brainstem responses (ABR) in normal hearing individuals.

Aim: to evaluate the clinical applicability of bone conduction ABR, characterizing normality and determining an assessment protocol.

Method: participants of this study were 22 individuals with normal hearing (20dB NA), with ages between 20 and 30 years, 14 female and 8 male.
