    (2016) KAZAN, Hellen Medeiros; SAMELLI, Alessandra Giannella; NEVES-LOBO, Ivone Ferreira; MAGLIARO, Fernanda Cristina Leite; LIMONGI, Suelly Cecília Olivan; MATAS, Carla Gentile
    ABSTRACT Introduction Few studies have performed Brainstem (BAEP) and P300 Auditory Evoked Potentials simultaneously to assess central auditory pathways in normal hearing individuals with Down syndrome (DS), mainly because of the difficulty in applying these procedures to this population. Previous studies have suggested that individuals with DS might present different patterns of response compared with those of individuals with typical development; nevertheless, the identification of these potentials would be crucial for the establishment of an accurate audiological diagnosis. Purpose To characterize BAEP and P300 in normal-hearing individuals with DS. Methods BAEP and P300 were analyzed in 17 individuals with DS and in 21 individuals with typical development aged 7 to 15 years. The results were quantitatively and qualitatively analyzed using descriptive measures and hypothesis tests. Results In the quantitative analysis, latency values were lower in the BAEP for the DS group, with statistically significant difference for wave V and interpeaks III-V and I-V; there were no significant differences in the P300 latency values. In the qualitative analysis, there were a larger number of individuals with early values for BAEP latencies and late latencies for P300 in the DS group; both comparisons showed statistically significant differences. Conclusion Children and adolescents with DS can present early responses to the components of BAEP, suggesting that their auditory pathway requires less time for the neural transmission of acoustic stimuli to the brainstem. Concerning P300, individuals with DS may present increased latencies, suggesting impairment in the central auditory pathway for the cortical processing of auditory information.

    Evaluation of peripheral auditory pathways and brainstem in obstructive sleep apnea
    (2018) MATSUMURA, Erika; MATAS, Carla Gentile; MAGLIARO, Fernanda Cristina Leite; PEDRENO, Raquel Meirelles; LORENZI-FILHO, Geraldo; SANCHES, Seisse Gabriela Gandolfi; CARVALLO, Renata Mota Mamede
    Introduction: Obstructive sleep apnea causes changes in normal sleep architecture, fragmenting it chronically with intermittent hypoxia, leading to serious health consequences in the long term. It is believed that the occurrence of respiratory events during sleep, such as apnea and hypopnea, can impair the transmission of nerve impulses along the auditory pathway that are highly dependent on the supply of oxygen. However, this association is not well established in the literature. Objective: To compare the evaluation of peripheral auditory pathway and brainstem among individuals with and without obstructive sleep apnea. Methods: The sample consisted of 38 adult males, mean age of 35.8 (+/- 7.2), divided into four groups matched for age and Body Mass Index. The groups were classified based on polysomnography in: control (n = 10}. mild obstructive sleep apnea (n = 11) moderate obstructive sleep apnea (n=8) and severe obstructive sleep apnea (n = 9}. All study subjects denied a history of risk for hearing loss and underwent audiometry, tympanometry, acoustic reflex and Brainstem Auditory Evoked Response. Statistical analyses were performed using three-factor ANOVA, 2 factor ANOVA, chi-square test, and Fisher's exact test. The significance level for all tests was 5%. Results: There was no difference between the groups for hearing thresholds, tympanometry and evaluated Brainstem Auditory Evoked Response parameters. An association was observed between the presence of obstructive sleep apnea and changes in absolute latency of wave V (p = 0.03). There was an association between moderate obstructive sleep apnea and change of the latency of wave V (p = 0.01). Conclusion: The presence of obstructive sleep apnea is associated with changes in nerve conduction of acoustic stimuli in the auditory pathway in the brainstem. The increase in obstructive sleep apnea severity does not promote worsening of responses assessed by audiometry, tympanometry and Brainstem Auditory Evoked Response.

    Cortical maturation in children with cochlear implants: Correlation between electrophysio-logical and behavioral measurement
    (2017) SILVA, Liliane Aparecida Fagundes; COUTO, Maria Ines Vieira; MAGLIARO, Fernanda C. L.; TSUJI, Robinson Koji; BENTO, Ricardo Ferreira; CARVALHO, Ana Claudia Martinho de; MATAS, Carla Gentile
    Central auditory pathway maturation in children depends on auditory sensory stimulation. The objective of the present study was to monitor the cortical maturation of children with cochlear implants using electrophysiological and auditory skills measurements. The study was longitudinal and consisted of 30 subjects, 15 (8 girls and 7 boys) of whom had a cochlear implant, with a mean age at activation time of 36.4 months (minimum, 17 months; maximum, 66 months), and 15 of whom were normal-hearing children who were matched based on gender and chronological age. The auditory and speech skills of the children with cochlear implants were evaluated using GASP, IT-MAIS and MUSS measures. Both groups underwent electrophysiological evaluation using long-latency auditory evoked potentials. Each child was evaluated at three and nine months after cochlear implant activation, with the same time interval adopted for the hearing children. The results showed improvements in auditory and speech skills as measured by IT-MAIS and MUSS. Similarly, the long-latency auditory evoked potential evaluation revealed a decrease in P1 component latency; however, the latency remained significantly longer than that of the hearing children, even after nine months of cochlear implant use. It was observed that a shorter P1 latency corresponded to more evident development of auditory skills. Regarding auditory behavior, it was observed that children who could master the auditory skill of discrimination showed better results in other evaluations, both behavioral and electrophysiological, than those who had mastered only the speech-detection skill. Therefore, cochlear implant auditory stimulation facilitated auditory pathway maturation, which decreased the latency of the P1 component and advanced the development of auditory and speech skills. The analysis of the long-latency auditory evoked potentials revealed that the P1 component was an important biomarker of auditory development during the rehabilitation process.

    Audiological manifestations in HIV-positive adults
    (2014) MATAS, Carla Gentile; ANGRISANI, Rosanna Giaffredo; MAGLIARO, Fernanda Cristina Leite; SEGURADO, Aluisio Augusto Cotrim
    OBJECTIVE: To characterize the findings of behavioral hearing assessment in HIV-positive individuals who received and did not receive antiretroviral treatment. METHODS: This research was a cross-sectional study. The participants were 45 HIV-positive individuals (18 not exposed and 27 exposed to antiretroviral treatment) and 30 control-group individuals. All subjects completed an audiological evaluation through pure-tone audiometry, speech audiometry, and high-frequency audiometry. RESULTS: The hearing thresholds obtained by pure-tone audiometry were different between groups. The group that had received antiretroviral treatment had higher thresholds for the frequencies ranging from 250 to 3000 Hz compared with the control group and the group not exposed to treatment. In the range of frequencies from 4000 through 8000 Hz, the HIV-positive groups presented with higher thresholds than did the control group. The hearing thresholds determined by high-frequency audiometry were different between groups, with higher thresholds in the HIV-positive groups. CONCLUSION: HIV-positive individuals presented poorer results in pure-tone and high-frequency audiometry, suggesting impairment of the peripheral auditory pathway. Individuals who received antiretroviral treatment presented poorer results on both tests compared with individuals not exposed to antiretroviral treatment.

    Influence of obstructive sleep apnea on auditory event-related potentials
    (2022) PEDRENO, Raquel Meirelles; MATSUMURA, Erika; SILVA, Liliane Aparecida Fagundes; SAMELLI, Alessandra Giannella; MAGLIARO, Fernanda Cristina Leite; SANCHES, Seisse Gabriela Gandolfi; LOBO, Ivone Ferreira Neves; LORENZI-FILHO, Geraldo; CARVALLO, Renata Mota Mamede; MATAS, Carla Gentile
    Purpose To evaluate the influence of obstructive sleep apnea (OSA) on the P300 response of auditory event-related potentials (ERPs) and to correlate the electrophysiological findings with OSA severity. Methods Patients with no OSA and mild, moderate, and severe OSA according to polysomnography (PSG) with normal hearing and no comorbidities were studied. Individuals with a body mass index (BMI) >= 40 kg/m(2), hypertension, diabetes, dyslipidemia, the use of chronic medications, and a risk of hearing loss were excluded. All patients underwent full PSG and auditory ERP measurement using the oddball paradigm with tone burst and speech stimuli. For P300 analysis (latencies and amplitudes), normal multiple linear regression models were adjusted with the groups (No OSA, Mild OSA, Moderate OSA, Severe OSA), age, BMI, and Epworth score as explanatory variables. Results We studied 54 individuals (47 males) aged 35 +/- 8 years with a BMI of 28.4 +/- 4.3 kg/m(2). Patients were divided according to the apnea-hypopnea index (AHI) derived from PSG into no OSA (n = 14), mild (n = 16), moderate (n = 12), and severe OSA (n = 12) groups. Patients with severe OSA presented prolonged P300 latencies with tone burst stimuli compared to patients with no OSA and those with mild and moderate OSA. Conclusion Severe OSA is associated with impairment of the P300 response of auditory ERPs, suggesting a decrease in the processing speed of acoustic information that may be mediated by the level of somnolence.

    Peripheral and central auditory assessment in among the elderly
    (2016) SAMELLI, Alessandra Giannella; MATAS, Carla Gentile; RABELO, Camila Maia; MAGLIARO, Fernanda Cristina Leite; LUIZ, Natália Paião; SILVA, Lidiane Dias
    Abstract Introduction: Presbycusis can affect different portions of the auditory system, causing impacts of varying degrees of seriousness on the daily routine of elderly persons. It is essential that the extent of the deficit as well as the degree of handicap is evaluated, so that the hearing of the elderly can be effectively rehabilitated, improving their quality of life. Purpose: To characterize the peripheral and central hearing of elderly individuals and assess their auditory handicaps. Methods: A cross sectional observational study was performed. We evaluated 83 elderly persons (60-85 years; 33 men, 50 women) with normal hearing or sensorineural hearing loss. Individuals were divided into 3 groups according to the 3 to 6kHz hearing thresholds: G1 - mean of 0 to 39 dBHL (80 ears); G2 - mean of 40 to 59 dBHL (48 ears); G3 - mean of 60 to 120dBHL (38 ears). All individuals responded to the Hearing Handicap Inventory for the Elderly (HHIE), and underwent Pure Tone Audiometry, Auditory Brainstem Response (ABR) and Long Latency Response (P300) evaluation. Results: Men had higher auditory thresholds at frequencies from 500 to 12,000Hz (with a statistical difference between 2-8 kHz) and also significantly greater latencies for ABR components. There was no difference between genders for the P300 evaluation. Comparison between groups showed: a statistically significant difference for age; greater ABR wave latencies and interwave intervals; that questionnaire scores worsened as hearing threshold declined; and similar P300 latencies. Conclusions: Elderly people have impairment throughout the auditory pathway (peripheral and central). The P300 was less accurate at identifying the losses that come with age. The HHIE demonstrated negative effects on the social life of elderly people, agreeing with the hearing thresholds found.

    Programa de treinamento auditivo em portadores de zumbido
    (2016) TUGUMIA, Daniele; SAMELLI, Alessandra Giannella; MATAS, Carla Gentile; MAGLIARO, Fernanda Cristina Leite; RABELO, Camila Maia
    ABSTRACT Tinnitus may be defined as the conscious perception of sound or noise, without the presence of external acoustic stimulation. Given the damage caused by tinnitus and the lack of effective treatment, alternatives are necessary to rehabilitate subjects with tinnitus. There is an assumption that auditory training (AT) could lead to a plastic reorganization of this system, thus promoting an improvement of the symptom. Objective: To verify the effect of an AT program in subjects with tinnitus in the perception of this symptom. Methods: Twelve subjects with tinnitus were included in the study and divided into two groups: Study Group (SG) and Control Group (CG). All of them underwent audiometric and electrophysiological assessments; acuphenometry; Tinnitus Handicap Inventory and auditory processing assessment (GIN - Gaps in Noise, Frequency Pattern Test and Speech-in-Noise). Afterward, trainings began and the SG was submitted to the formal AT, and the CG to the visual training. Results: In the characterization of the groups, no statistically significant difference was found for the variables such as age, pitch, and loudness of tinnitus, or for hearing thresholds in conventional audiometry and high frequencies. Comparisons were performed between the groups, before and after the trainings, regarding electrophysiological, behavioral, and Tinnitus Handicap Inventory tests, and no statistically significant differences were found between them for any of the evaluations. Conclusion: Findings showed no statistically significant differences between groups in the comparison between the moments pre- and post-trainings (auditory or visual), nor for the electrophysiological findings or behavioral assessment of the auditory processing and for the Tinnitus Handicap Inventory, although some specific differences in the individual analysis have occurred.
