Auditory brainstem response in neonates: influence of gender and weight/gestational age ratio
(Sociedade de Pediatria de São Paulo, 2013-12-01) Angrisani, Rosanna M. Giaffredo; Bautzer, Ana Paula D.; Matas, Carla Gentile; Azevedo, Marisa Frasson de [UNIFESP]; Universidade Federal de São Paulo (UNIFESP); Universidade de São Paulo (USP)
OBJECTIVE:To investigate the influence of gender and weight/gestational age ratio on the Auditory Brainstem Response (ABR) in preterm (PT) and term (T) newborns.METHODS:176 newborns were evaluated by ABR; 88 were preterm infants - 44 females (22 small and 22 appropriate for gestational age) and 44 males (22 small and 22 appropriate for gestational age). The preterm infants were compared to 88 term infants - 44 females (22 small and 22 appropriate for gestational age) and 44 males (22 small and 22 appropriate for gestational age). All newborns had bilateral presence of transient otoacoustic emissions and type A tympanometry.RESULTS:No interaural differences were found. ABR response did not differentiate newborns regarding weight/gestational age in males and females. Term newborn females showed statistically shorter absolute latencies (except on wave I) than males. This finding did not occur in preterm infants, who had longer latencies than term newborns, regardless of gender.CONCLUSIONS:Gender and gestational age influence term infants' ABR, with lower responses in females. The weight/gestational age ratio did not influence ABR response in either groups.

(Associação Brasileira de Otorrinolaringologia e Cirurgia Cervicofacial, 2011-06-01) Arnaut, Mirian Aratangy; Agostinho, Caroline Vieira; Pereira, Liliane Desgualdo [UNIFESP]; Weckx, Luc Louis Maurice [UNIFESP]; Ávila, Clara Regina Brandão de [UNIFESP]; University of São Paulo Speech and Hearing Department Graduate Program in Human Communication Disorders; Universidade Federal de São Paulo (UNIFESP)
Contemporary cross-sectional cohort study. There is evidence of the auditory perception influence on the development of oral and written language, as well as on the self-perception of vocal conditions. The auditory system maturation can impact on this process. OBJECTIVE: To characterize the auditory skills of temporal ordering and localization in dysphonic children. MATERIALS AND METHODS: We assessed 42 children (4 to 8 years). Study group: 31 dysphonic children; Comparison group: 11 children without vocal change complaints. They all had normal auditory thresholds and also normal cochleo-eyelid reflexes. They were submitted to a Simplified assessment of the auditory process (Pereira, 1993). In order to compare the groups, we used the Mann-Whitney and Kruskal-Wallis statistical tests. Level of significance: 0.05 (5%). RESULTS: Upon simplified assessment, 100% of the Control Group and 61.29% of the Study Group had normal results. The groups were similar in the localization and verbal sequential memory tests. The nonverbal sequential memory showed worse results on dysphonic children. In this group, the performance was worse among the four to six years. CONCLUSION: The dysphonic children showed changes on the localization or temporal ordering skills, the skill of non-verbal temporal ordering differentiated the dysphonic group. In this group, the Sound Location improved with age.

(ABORL-CCF Associação Brasileira de Otorrinolaringologia e Cirurgia Cérvico-Facial, 2004-08-01) Miranda, Eliana S. [UNIFESP]; Pereira, Liliane Desgualdo [UNIFESP]; Bommarito, Silvana [UNIFESP]; Silva, Tarcimara M.; Universidade Federal de São Paulo (UNIFESP); Unicentro Metodista Izabela Hendrix
Auditory processing, as we understand, refers to how the individual handles with auditory information. The importance of auditory perception of sound sequences and temporal patterns in acquiring and comprehending symbolic components of language is well recognized. Acoustic properties of speech may be limited to the basic components of duration and frequency analysis. Speech signals are the most important events we receive through hearing and, as we know, speech patterns may be compromised in Parkinson's disease. AIM: To evaluate the performance of subjects diagnosed with Parkinson's disease in Duration and Frequency Pattern Tests. STUDY DESIGN: Clinical prospective. MATERIAL AND METHOD: Nonverbal stimuli identification was evaluated in three different modes of response: humming, verbal labeling and indicating. Stimuli were characterized by sequences of three or four elements, varying in duration and frequency. RESULTS: No significant difference was observed considering mode of response; better results were obtained for three-element sequences than four-element sequences and for duration patterns in comparison to frequency patterns. Subjects with Parkinsons's disease demonstrated poorer performance than normal subjects. CONCLUSION: Temporal ordering is a very important function of the central auditory nervous system. This ability enables the listener to discriminate sound patterns based on auditory ordering or sequencing. Therefore, our findings are important since they stimulate further studies concerning analysis and interpretation processes in patients with Parkinson's disease.

(Associação Brasileira de Otorrinolaringologia e Cirurgia Cervicofacial, 2012-08-01) Pinheiro, Maria Madalena Canina [UNIFESP]; Dias, Karin Ziliotto [UNIFESP]; Pereira, Liliane Desgualdo [UNIFESP]; Universidade Federal de Santa Catarina Curso de Fonoaudiologia; Universidade Federal de São Paulo (UNIFESP)
Aging can alter temporal processing and affect speech perception. AIM: To compare temporal processing auditory processing in elderly subject to and new hearing aid users. MATERIALS AND METHODS: The study included 60 elderly patients with bilateral sensorineural hearing loss. The procedures selected were the Duration Pattern Tests (DPT) and gaps in noise (GIN) test were used to analyze the responses of correct identification, and the temporal acuity threshold before and after the fitting of hearing aids. Study design: clinical and experimental research with non-probability sample of convenience. RESULTS: There was no statistically significant difference between the responses from GI and GII individuals. The elderly users of hearing aids had a lower gap detection threshold, greater recognition of gaps and of discrimination of the duration pattern in relation to when they were only potential users. CONCLUSION: There was a deterioration in temporal processing skills, regardless of hearing loss degrees. Thus, the effect of acoustic stimulation by the use of a hearing aid improved resolution and temporal ordering.

(ABORL-CCF Associação Brasileira de Otorrinolaringologia e Cirurgia Cérvico-Facial, 2007-02-01) Neves, Ivone Ferreira; Gonçalves, Isabela Crivellaro; Leite, Renata Aparecida; Magliaro, Fernanda Cristina Leite; Matas, Carla Gentile [UNIFESP]; Universidade de São Paulo (USP); FMABC; Universidade Federal de São Paulo (UNIFESP)
Contemporary cohort cross-sectional study. Introduction: The auditory middle latency response (AMLR) is generated between 10 and 80 ms and has multiple generators, with a greater contribution from the thalamus-cortical pathways. The establishment of normality criteria for latency and amplitude values is necessary for clinical use. AIM: to analyze the latency and amplitude of the AMLR in individuals without audiological disorders, and verify the reliability of Pa-Nb amplitude. MATERIALS AND METHODS: The AMLR of 25 individuals was collected during 2005 and the Na, Pa, Nb components were analyzed for each tested ear (A1 and A2), and electrode positioning (C3 and C4). RESULTS: A statistically significant difference was noticed among middle latency values for C3A1 and C4A1 regarding components Na and Pa, and no difference for component Nb and mean values for amplitudes Na-Pa and Pa-Nb. Conclusions: We established average and standard deviation values for latency and amplitude parameters for components Na, Pa, Nb and Na-Pa and Pa-Nb, under conditions C3A1, C4A1, C3A2, C4A2, providing a parameter for the analysis and interpretation of this potential.

(Assoc Brasileira Otorrinolaringologia & Cirurgia Cervicofacial, 2013-11-01) Lessa, Alexandre Hundertmarck; Costa, Maristela Julio [UNIFESP]; Universidade Federal de Sergipe (UFS); Universidade Federal de São Paulo (UNIFESP)
Difficulty understanding speech, particularly in situations unfavorable to communication, is a common complaint among elderly individuals.Objective: to verify the variables connected to hearing loss and stimulus presentation rate and their impact on the speech recognition skills of elderly subjects in quiet and noisy environments.Method: this case-control study included two groups of subjects (31 elderly subjects with normal hearing and 26 with hearing loss) exposed to the List of Sentences in Portuguese and the Slowed List of Sentences in Portuguese tests. Sentence recognition indices were calculated for tests done against noisy and quiet backgrounds at a normal and reduced speech rate. Data sets were submitted to statistical analysis.Results: elderly subjects from both groups had better test results when sentences were played at a slower rate. Statistically significant difference was seen for both groups when the tests were carried out on a quiet background and for the group with hearing loss when tested on a noisy background.Conclusion: regardless of their peripheral hearing, the elderly subjects included in this study were more able to recognize speech when sentences were played at a slower rate against a quiet background. When sentences were played against a noisy background, the elderly subjects with hearing loss had more significant performance improvements than the ones with normal hearing when sentences were played at a slower rate.

Ocorrência de reflexo acústico alterado em desordens do processamento auditivo
(ABORL-CCF Associação Brasileira de Otorrinolaringologia e Cirurgia Cérvico-Facial, 2001-11-01) Meneguello, Juliana; Domenico, Márcia L. D.; Costa, Marianni C. M.; Leonhardt, Fernando D. [UNIFESP]; Barbosa, Luiz H. F. [UNIFESP]; Pereira, Liliane Desgualdo [UNIFESP]; Universidade Federal de São Paulo (UNIFESP)
Introduction: The acoustic reflex threshold is defined as the lowest sound intensity capable of starting the middle ear protection mechanism due to intense sounds (Metz, 1952; Jerger, 1970), being necessary the structural and functional integrity of the periferic and central auditory system. These structures are also responsable for the central processing of auditory information. Aim: We intend to verify whether acoustic reflex abnormalities can also appear in auditory processing (AP) disorders, resulting in symptoms related to speech and language disorders. Study design: Prospective randomized. Material and method: Data were analyzed from one hundred AP assessments, using Pereira (1997) method. Patients, male and female, with ages ranging from 07 to 18 years, had normal hearing thresholds and normal tympanograms patterns. The difference between the acoustic reflex and hearing thresholds defined the acoustic reflex level (ARL), considered normal between 70-90dB and altered when above of this range or when absent in one or more frequencies (Carvallo, 1996; 1997; Metz, 1952). Results: Disorders of AP were found in 97% of the patients. In this group, 62% showed ARL abnormalities, being statistically significant. Furthermore, patients with AP disorders showed ARL alterations, more frequently on severe degree disorders, on patients with combined auditory gnosis impairments and on patients with more than one auditory ability altered. Conclusion: Patients with acoustic reflex alterations and normal audiometry should perform the AP assessment, as these symptoms could unmask pathologies of the central nervous system.

(ABORL-CCF Associação Brasileira de Otorrinolaringologia e Cirurgia Cérvico-Facial, 2006-12-01) Viveiros, Carla Mherlyn [UNIFESP]; Pereira, Liliane Desgualdo [UNIFESP]; Mastroianni Kirsztajn, Gianna [UNIFESP]; Universidade Federal de São Paulo (UNIFESP)
Alport s Syndrome is characterized by the presence of renal, hearing and visual disorders. Objective: To characterize the TOAE and the MOES activity (suppression effect) in individuals with Alport s Syndrome. MATERIAL AND METHOD: This is a prospective study of a sample included ten individuals with a diagnosis of Alport s Syndrome. MOES recording was made in the presence and absence of contralateral stimulation (CLS) stimulation using the computer software ILO 92 - Otodynamics. RESULTS: TOAE was present in the global response (A) and in frequency ranges of 1000, 1500, 2000 and 3000 Hz in 4 individuals (40%), and absent in 6 individuals (60%) with hearing loss. We observed no responses at 4000 Hz in the right and left ears. Individuals that presented global responses to TOAE also suppressed that response when there was noise. CONCLUSION: The suppression effect also occurs with TOAE, suggesting that the hearing loss is predominantly the result of cochlear dysfunction.

(ABORL-CCF Associação Brasileira de Otorrinolaringologia e Cirurgia Cérvico-Facial, 2004-04-01) Pinheiro, Maria Madalena Canina [UNIFESP]; Pereira, Liliane Desgualdo [UNIFESP]; Universidade Federal de São Paulo (UNIFESP)
Presbyacusis is a hearing loss combined with functional auditory decline due to the aging process. AIM: The aim of this study is to characterize verbal and nonverbal sound interaction aspects in elderly individuals with and without hearing loss by means of Binaural Fusion Test, Sound Localization Test at five directions and Pediatric Sentence Identification (PSI), taking into consideration each procedure and hearing loss magnitude. STUDY DESIGN: Clinical study with transversal cohort. MATERIAL AND METHOD: A number of 110 elderly individuals, aged between 60 to 85 years, with normal hearing and with symmetric neurossensorial hearing loss up to moderately severe hearing impairment participated in this study. The common auditory behavior for all the selected tests was nominated as interaction. The analysis was performed by means of a single procedure and also based on audiometric magnitude. RESULTS: There were more individuals that failed the Binaural Fusion Test. The procedures that showed significant statistical dependency on the audiometric magnitude groups were Sound Localization Test, Temporal Lateralization Test and PSI-MCI (-10) Test. CONCLUSION: Elderly individuals present difficulty in the binaural interaction process when the auditory information is not complete. The magnitude of the hearing loss interfered specially in the localization auditory behavior.

Processamento auditivo em indivíduos com epilepsia de lobo temporal
(ABORL-CCF Associação Brasileira de Otorrinolaringologia e Cirurgia Cérvico-Facial, 2006-08-01) Meneguello, Juliana; Leonhardt, Fernando Danelon [UNIFESP]; Pereira, Liliane Desgualdo [UNIFESP]; Universidade Federal de São Paulo (UNIFESP)
Temporal epilepsy, one of the most common presentation of this pathology, causes excessive electrical discharges in the area where we have the final station of the auditory pathway. Both the anatomical and functional integrity of the auditory pathway structures are essential for the correct processing of auditory stimuli. AIM: to check the Auditory Processing in patients with temporal lobe epilepsy regarding the auditory mechanisms of discrimination from sequential sounds and tone patterns, discrimination of the sound source direction and selective attention to verbal and nonverbal sounds. METHOD: eight individuals with temporal lobe epilepsy were assessed, after excluding those with non-confirmed diagnosis or with the focus of discharges not limited to this lobe. The evaluation was carried out through special auditory tests: Sound Localization Test, Duration Pattern Test, Digits Dichotic Test and Non-Verbal Dichotic Test. Their performances were compared to the performances of individuals without neurological diseases (case-control study). RESULTS: similar performances were observed between patients with temporal lobe epilepsy and the control group regarding the auditory mechanism of sound source direction discrimination. Comparing the other auditory mechanisms assessed, the patients with temporal lobe epilepsy presented worse results. CONCLUSION: individuals with temporal lobe epilepsy had more deficits in auditory processing than those without cortical damage.

The aim of this study was to analyze the auditory behavior in Pitch(PPS) and Duration(DPS)Pattern Sequence tests and in the Dichotic Listening (Dichotic Digits Test/DDT) of familiar and unfamiliar words (Staggered Spondaic Words/SSW) in Japanese descendants that speak Japanese and Japanese descendants that do not speak Japanese, and to compare these findings with a group of non-Japanese descendants who have no contact with the Japanese language. METHOD: 60 High School graduates aged 17 to 40 years were evaluated. Subjects were divided into three groups: GJJ, Japanese descendants that speak Brazilian Portuguese and Japanese; GJP, Japanese descendants that speak Portuguese and do not speak Japanese; GBP non-oriental descendants that speak Brazilian Portuguese. All subjects filled in a questionnaire about their languages and musical abilities. Their ability in pattern-recognition tests was assessed by the PPS and DPS tests, their ability to recognize familiar words was tested by DDT and their ability to recognize unfamiliar words was tested by SSW. Results. GJJ and GJP showed higher performances than the group of Brazilians (GBP) in the PPS. RESULTS: show a statistically significant difference among the groups with a higher mean for the SSW results in GJJ compred to GJP and GBP. CONCLUSION:The results of SSW test seem to be influenced by bilingualism.

(Assoc Brasileira Otorrinolaringologia & Cirurgia Cervicofacial, 2011-09-01) Sens, Patricia Maria; Ribeiro de Almeida, Clemente Isnard; Neves de Souza, Marisa Mara [UNIFESP]; Goncalves, Josyane Borges A.; Carmo, Luiz Claudio do; FCMSCSP; Universidade Federal de São Paulo (UNIFESP); Sch Med Sci Santa Casa Sao Paulo
The Synthetic Sentence Identification (SSI) test assesses central auditory pathways by measuring auditory and visual sensitivity and testing selective attention. Cerebellum activation in auditory attention and sensorial activity modulation have already been described. Assessing patients with cerebellar lesions alone using the SSI test can confirm the role of the cerebellum in auditory processing.Aim: To evaluate the role of the cerebellum in auditory processing in individuals with normal hearing and in those with chronic cerebellum lesions, using the SSI test. Materials and Methods: Cross-sectional cohort study. A study group comprising 18 patients with chronic cerebellar lesion and a control group of 20 healthy individuals were assessed. The SSI test was applied in an Ipsilateral Competitive Message (ICM) and Contralateral Competitive Message (CCM) modes. To compare the results between groups, we used the chi-square test for qualitative variables.Results: A statistically significant difference was found between the study and control groups using the ICM mode of the SSI test (p=0.035), but not in the CCM mode (p=0.083).Conclusion: The results on the SSI confirmed cerebellar participation in auditory processing in individuals with chronic cerebellar lesions and in those with normal hearing assessed in this study.

(Assoc Brasileira Otorrinolaringologia & Cirurgia Cervicofacial, 2013-05-01) Amaral, Maria Isabel Ramos do; Faria Martins, Paula Maria; Colella-Santos, Maria Francisca [UNIFESP]; Universidade Estadual de Campinas (UNICAMP); State Univ Midwest; Universidade Federal de São Paulo (UNIFESP)
Temporal resolution enables the identification of fine differences in speech segmental aspects. Random Gap Detection Test (RGDT) and Gaps-In-Noise Test (GIN) evaluate such skills, by using different acoustic parameters.Objective: To compare the performance of normal school aged children without learning disabilities and/or hearing complaints in the GIN and RGDT, and analyze potential performance differences in these two procedures.Method: Cross sectional contemporary cohort study. 28 children, aged 8-10 years were evaluated. After peripheral audiological evaluation, RGDT and GIN were performed.Results: There were no statistical differences in performance between gender and age on the RGDT and GIN tests, between the right and left ears on the GIN test, and between frequencies on the RGDT test. the mean detection threshold gap for RGDT was 9.25 +/- 3.67 ms, and for GIN was 4.32 +/- 0.61 ms (right ear) and 4.43 +/- 0.79 ms (left ear). the results of the GIN Test were statistically lower than those from the RGDT (p < 0.001).Conclusion: Both tests indicated normal temporal resolution for all 28 children. GIN test presents advantages regarding the ease of application, task variable, stimuli and presentations form. However, the RGDT has advantages concerning the time required for administration and scoring.

(Assoc Brasileira Otorrinolaringologia & Cirurgia Cervicofacial, 2010-11-01) Amaral, Maria Isabel Ramos do; Colella-Santos, Maria Francisca [UNIFESP]; Universidade Estadual de Campinas (UNICAMP); Universidade Federal de São Paulo (UNIFESP)
Time resolution hearing skill is the minimum time necessary to solve acoustic events, which is fundamental for speech understanding, and which may be assessed by gap-detection tests, such as the Gaps-in-noise test (GIN).Aim: the purpose of this study was to verify the performance of time processing ability in children with no hearing and/or education difficulties by applying the GIN test in both genders and ages from 8 to 10 years.Study design: a prospective cross-sectional contemporary cohort.Material and method: The GIN test was applied to 75 school-aged children separated into three groups by age.Results: The findings showed no statistical differences among age groups or ears. Males had slightly better responses than females on the percentage of correct responses only.Conclusion: The gap threshold and percentage of correct responses were calculated regardless of the ear, gender or age, and were respectively 4.7ms and 73.6%. Based on a 95% confidence interval, the cut-off criterion for normal and abnormal performance was 6.1ms for the mean gap detection threshold and 60% for the percentage of correct responses.
