Teste da orelhinha no Hospital São Vicente de Paulo: levantamento de dados

Purpose: to analyze the results in newborn hearing screening (NHS) conducted from July 2007 to July 2010, at Sao Vicente de Paulo Hospital (HSVP), in the city of Passo Fundo-RS. Method: analysis was performed on records from 7153 infants born alive, to verify the numbers of conducted trials, the results of passes and fails, the retest rates and false-positive rates of diagnosed hearing loss. Results: it was observed that from 7153 live births, 5045 (70.53%) went through newborn hearing screen. Of these, 760 (15%) failed and were referred to retest. The retest information was available only of 377 (49,60%) neonates. From them, 353 (93.63%) passed, 13 (3.44%) failed, 10 (2.65%) attended the retest and did not do it and 1 (0.26%) was death. After the data analysis, it was found that retesting rates were 15% and false-positive were 93.63%. In addition, the incidence of hearing impairment confirmed by the sample was 0.0039%. Conclusion: in this study it can be conclude that the results of neonatal hearing screening of HSVP are not in agreement with the literature and with the provisions of Municipal Act 4373. It is suggested that some strategies are also used to reduce the rate of false-positive and proper coordination of the screening program and early intervention.

Auditory brainstem response in gas station attendants

Ototoxicity of organic solvents can affect the hearing system up to the cochlea level and the central structures of hearing. OBJECTIVE: To evaluate the neurophysiological integrity of the hearing system in subjects exposed to fuels using ABR. METHOD: Prospective study. We evaluated attendants from three gas stations in Santa Maria/RS. The sample had 21 subjects, who were evaluated by auditory brainstem response. RESULTS: We found an alteration in the absolute latencies of Waves I and III and in all the interpeak latencies, in the right ear. In the left ear there was a change in the absolute latencies of all Waves, and in all the interpeak intervals. A change in the interaural difference of Wave V was found in 19% of the individuals. In the group exposed for more than five years, there were subjects with a statistically significant changes: in the I-V interpeak of the right ear; in the absolute latency of Wave I and in the III-V interpeak of the left year. CONCLUSION: Exposure to fuels can cause alterations in the central hearing system.UNLABELLED Ototoxicity of organic solvents can affect the hearing system up to the cochlea level and the central structures of hearing.

Avaliação simplificada e comportamental do processamento auditivo em escolares: estabelecendo relações

Purpose to characterize the auditory processing of students who failed in the simplified evaluation of the auditory processing and compare these found results with the results in the behavioral auditory processing evaluation. Methods it was performed the basic audiological evaluation (vocal and tonal audiometry and acoustic immitance measurements), the behavioral battery of the auditory processing, composed by the PSI (Pediatric Speech Intelligibility) portuguese version, PPS (Pitch Pattern Sequence), MLD (Masking Level Difference), SSW (Stagged Spondaic Words) portuguese version and GIN (Gap in Noise), and the retest of the simplified evaluation of the auditory processing with students from nine to fourteen years old registered between 4th to 8th grade of a public school in Porto Alegre. Results ten (90,9%) out of the eleven evaluated students that failed in the simplified evaluation showed alterations in the behavioral battery of auditory processing tests. The subprofiles which had the major number of alterations were the ones of decoding and integration, the most impaired auditory abilities were binaural interaction and separation and binaural integration concomitantly. There was no relevant association between the tasks of the simplified evaluation and the tests of the behavioral battery when comparing the same neuralphisiological report or similar task. Conclusion it was possible to characterize the auditory processing of the analyzed students. From the comparison between the simplified evaluation and the behavioral battery it was noted that the simplified evaluation can be a sensible predictor to the alterations of the auditory processing, in spite of not identifying the specific association between the compared abilities.

Relação entre os achados do teste masking level difference e do reflexo acústico em crianças com transtorno fonológico

PURPOSE: to investigate the findings of Masking Level Difference and acoustic reflex tests along with the composition of the phonological system of children with Phonological Disorder, to determine whether these associations can assist in understanding the process of acquisition of atypical language. METHODS: a quantitative, observational and descriptive study, developed through secondary survey of a database, consisting of speech therapy evaluations of 110 children with Phonological Disorder, ages 5 - 10 years. The inclusion criteria for this study required all prospective subjects to have undergone tympanometry with type A (Jerger) tympanogram as well as a Masking Level Difference test evaluation. RESULTS: data from 110 children, 57 suited inclusion criteria, population composition: (42 male and 15 female). Of the 57 children, 23 (40.3%) had normal Masking Level Difference results and 34 (59.7%) had altered results. The relationship between the Masking Level Difference test and the variables age, sex, degree of speech intelligibility, and the result of contralateral and ipsilateral acoustic reflex were not observed to be statistically significant. The relationship between phonological acquisition of the phonemes in initial and medial onset with the results of the Masking Level Difference test was found to be statistically significant with the non-acquisition of both early-onset phonemes / s / and /ʀ/ and /s/ e /z/ in medial onset observed in subjects with altered Masking Level Difference test results. CONCLUSION: other auditory processing abilities beyond the binaural interaction should be studied in order to identify their association with phonological disorder.

Parameters for Applying the Brainstem Auditory Evoked Potential with Speech Stimulus: Systematic Review

Introduction  Studies using the Brainstem Auditory Evoked Potential with speech stimulus are increasing in Brazil, and there are divergences between the methodologies used for testing. Objectives  To analyze the parameters used in the study of the Brainstem Auditory Evoked Potentials with speech stimulus. Data Synthesis  The survey was performed using electronic databases. The search strategy was as follows: “Evoked potentials, auditory” OR “Brain stem” OR “Evoked potentials, auditory, brain stem” AND “Speech.” The survey was performed from June to July of 2016. The criteria used for including articles in this study were: being written in Portuguese, English or Spanish; presenting the description of the testing parameters and the description of the sample. In the databases selected, 2,384 articles were found, and 43 articles met all of the inclusion criteria. The predominance of the following parameters was observed to achieve the potential during study: stimulation with the syllable /da/; monaural presentation with greater use of the right ear; intensity of 80 dB SPL; vertical placement of electrodes; use of in-ear headphones; patient seated, distracted in awake state; alternating polarity; use of speech synthesizer software for the elaboration of stimuli; presentation rate of 10.9/s; and sampling rate of 20 kHz. Conclusions  The theme addressed in this systematic review is relatively recent. However, the results are significant enough to encourage the use of the procedure in clinical practice and advise clinicians about the most used procedures in each parameter.
