- Caracterização eletrofisiológica da audição em indivíduos com Síndrome de Down(2016) KAZAN, Hellen Medeiros; SAMELLI, Alessandra Giannella; NEVES-LOBO, Ivone Ferreira; MAGLIARO, Fernanda Cristina Leite; LIMONGI, Suelly Cecília Olivan; MATAS, Carla GentileABSTRACT 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.
- Evolução audiométrica em usuários de implante coclear multicanal(2013) HOSHINO, Ana Cristina Hiromi; CRUZ, Dorilan Rodriguez da; GOFFI-GOMEZ, Maria Valéria Schmidt; BEFI-LOPES, Débora Maria; MATAS, Carla Gentile; FORTUNATO-TAVARES, Talita M.; TSUJI, Robinson KojiPURPOSE: to evaluate how long after activation one can achieve the desired auditory thresholds in individuals multichannel cochlear implant users from different age groups. METHOD: a retrospective cross-sectional from a database, approved by CEP / FMUSP, under number 779/06. Individuals implanted between January 2005 and September 2008, whose files had preoperative audiometric data and 3, 6 and 12 months after CI were included. Seventy-two patients fulfilled the criteria, and they were divided in two groups according to age: group I (17 year old) and GII (18-66 year old). Analysis of variance (ANOVA) of one factor in order to verify the interaction between the mean threshold and time after CI were used. RESULTS: we observed that 15 of the GI have reached around 30dBNA thresholds at 3 months after implant. The same happened to 26 patients of GII. We found significant interaction between time (F (3.140) = 91.973, p = 0.00) and the average hearing thresholds. Post-hoc analysis in the GI group were statistically significant differences for comparisons between HA and 3 months after implantation (p = 0.00) and between 3 and 12 months (p = 0.28). For GII only for comparison between HA and 3 months (p = 0.00). CONCLUSION: a significant hearing change may be observed beginning from three months after IC, but this result is not found in all implanted subjects.
- Auditory pathway maturational study in small for gestational age preterm infants(2014) ANGRISANI, Rosanna Giaffredo; DINIZ, Edna Maria Albuquerque; GUINSBURG, Ruth; FERRARO, Alexandre Archanjo; AZEVEDO, Marisa Frasson de; MATAS, Carla GentilePURPOSE: To follow up the maturation of the auditory pathway in preterm infants small for gestational age (SGA), through the study of absolute and interpeak latencies of auditory brainstem response (ABR) in the first six months of age. METHODS: This multicentric prospective cross-sectional and longitudinal study assessed 76 newborn infants, 35 SGA and 41 appropriate for gestational age (AGA), born between 33 and 36 weeks in the first evaluation. The ABR was carried out in three moments (neonatal period, three months and six months). Twenty-nine SGA and 33 AGA (62 infants), between 51 and 54 weeks (corrected age), returned for the second evaluation. In the third evaluation, 49 infants (23 SGA and 26 AGA), with age range from 63 to 65 weeks (corrected age), were assessed. The bilateral presence of Transient Evoked Otoacoustic Emissions and normal tympanogram were inclusion criteria. RESULTS: It was found interaural symmetry in both groups. The comparison between the two groups throughout the three periods studied showed no significant differences in the ABR parameters, except for the latencies of wave III in the period between three and six months. As for the maturation with tone burst 0.5 and 1 kHz, it was found that the groups did not differ. CONCLUSION: The findings suggest that, in the premature infants, the maturational process of the auditory pathway occurs in a similar rate for SGA and AGA. These results also suggest that prematurity is a more relevant factor for the maturation of the auditory pathway than birth weight.
- Características da avaliação auditiva na síndrome de Williams: revisão sistemática(2018) SILVA, Liliane Aparecida Fagundes; KIM, Chong Ae; MATAS, Carla GentileABSTRACT Purpose Identify the characteristics of the clinical audiological evaluation of individuals with Williams syndrome by means of a systematic literature review. Research strategies The following research question was initially determined: “What are the characteristics of clinical auditory assessment in individuals with Williams syndrome?”. From this, a bibliographic search was conducted in four databases using the descriptors: Williams syndrome, Hearing loss, and Audiology. Selection criteria Only full articles with evidence levels 1 or 2, published in Brazilian Portuguese or English, were selected. Data analysis Results obtained in the auditory tests used in the clinical routine, namely: immittance test, pure-tone audiometry, otoacoustic emissions, and brainstem auditory evoked potential were analyzed. Results Two hundred nine studies were found, but only 12 met the inclusion criteria for the study. It was possible to observe prevalence of type A tympanometry curve, which may occur with absence of acoustic reflexes, mild to moderate sensorineural hearing loss, affecting mainly the high frequencies, absent or less amplified otoacoustic emissions, and brainstem auditory evoked potential without retrocochlear alteration. Conclusion Cochlear impairment is common in individuals with Williams syndrome and the main disorders found in the hearing assessment in this population are absence of otoacoustic emissions and acoustic reflexes, as well as presence of mild to moderate sensorineural hearing loss, mainly in the high-frequency range, observed by audiometry.
- Audiological characteristics in mucopolysaccharidosis: a systematic literature review(2019) CHIMELO, Flávia Teixeira; SILVA, Liliane Aparecida Fagundes; KIM, Chong Ae; MATAS, Carla GentileABSTRACT Purpose: to describe the audiological characteristics of patients with mucopolysaccharidosis. Methods: after formulating the research question, three databases were considered for the search (Science Direct, Virtual Health Library and Web of Science); the following descriptors were used: mucopolysaccharidoses, hearing loss, and audiology. Articles were included that were original and complete, presenting audiological evaluation data in patients with mucopolysaccharidosis. Each study was classified according to the degree of recommendation and the level of scientific evidence, based on the criteria established by the Oxford Center for Evidence-based Medicine, and the results obtained from the evaluations were analyzed. Results: of the 499 articles found, eight met the inclusion criteria. Pure tone audiometry and tympanometry were performed in all studies. The incidence of hearing loss in patients with MPS ranged from 54% to 100% of the cases, with conductive hearing loss corresponding to 30% and 58.33%, mixed hearing loss corresponding to 28.5% and 66.66% and sensorineural hearing loss corresponding to less than 14%. None of the studies described the responses of otoacoustic emissions and auditory evoked potentials. Conclusion: the prevalence of hearing loss among individuals with MPS is higher than 54% of the cases, of which conductive and mixed are predominant.
- Quality of life evaluation in children with cochlear implants(2015) ALMEIDA, Renata Paula de; MATAS, Carla Gentile; COUTO, Maria Inês Vieira; CARVALHO, Ana Claudia Martinho dePURPOSE: To evaluate the quality of life of children with cochlear implants from the perspective of their parents. METHODS: A clinical and cross-sectional study was conducted with 15 parents of children using cochlear implants of both genders aged between 2 and 12 years old. Parents of these children answered the questionnaire ""Children with Cochlear Implants: Parental Perspective"" (CCIPP). Data related to auditory category and time of cochlear implants use were collected from medical records of the children. The percentages of responses on the CCIPP domains were tabulated and descriptively and inferentially analyzed. RESULTS: The cochlear implants had a positive effect on the quality of life of children in the self-reliance (58.9%) and social relationships (56.7%) domains. No correlation was observed between the time of cochlear implants activation (months) and any of the CCIPP domains. However, children with 24 months or less of cochlear implant use presented higher percentages on the communication domain than those with more than 24 months of cochlear implants use. A negative correlation was observed between the auditory category and the effects of the implant domain. CONCLUSION: From the perspective of parents, the use of cochlear implants improves the quality of life of their children; the shorter the time of cochlear implants use, the higher the improvement in quality of life; and the more developed the auditory skills, the lower the percentage of quality of life improvement with the cochlear implants.
- Estudo da função auditiva em indivíduos com HIV/AIDS submetidos e não submetidos à terapia antirretroviral(2013) QUIDICOMO, Simone; MATAS, Carla GentilePURPOSE: To characterize the audiologic manifestations in individuals with HIV/AIDS (Human Immunodeficiency Virus/Acquired Immunodeficiency Syndrome) submitted and not submitted to antiretroviral therapy. METHODS: The audiologic evaluation was carried out in 28 individuals in Research Group I (RGI) with HIV/AIDS submitted to antiretroviral therapy; 24 individuals in Research Group II (RGII) with HIV/AIDS not submitted to antiretroviral therapy, and 45 healthy individuals in the Control Group (CG). The audiologic tests that comprised this study were: Conventional Pure Tone Audiometry, Speech Audiometry and High Frequency Audiometry. RESULTS: There were differences between groups RGI and RGII regarding conventional audiologic evaluation and high frequency audiometry. There were higher thresholds for both Conventional and High Frequency Audiometries when compared with CG subjects, however without significant difference among RGI and RGII. CONCLUSION: Individuals with HIV/AIDS present more abnormal results in Conventional Pure Tone Audiometry and High Frequency Audiometry than healthy individuals (CG), which indicates impairment in the hearing system. Individuals with HIV/AIDS present more abnormal findings in High Frequency Audiometry when compared to Conventional Pure Tone Audiometry. There was no difference between individuals with HIV/AIDS submitted (RGI) and not submitted (RGII) to antiretroviral therapy regarding Conventional Pure Tone Audiometry and High Frequency Audiometry.
- Study of the peripheral and central auditory pathways in patients with mucopolysaccharidosis(2024) CHIMELO, Flavia Teixeira; SILVA, Liliane Aparecida Fagundes; NEVES-LOBO, Ivone Ferreira; KIM, Chong Ae; MATAS, Carla GentileObjective: To investigate the peripheral and central auditory pathways in mucopolysaccharidosis (MPS) individuals. Method: The research sample comprised 15 individuals (one female and 14 males), aged 8 to 46 years. The following procedures were used: medical history survey, otoscopy, speech and puretone threshold audiometry, acoustic immittance measures, and central auditory pathway assessment with brainstem auditory evoked potentials (BAEP) and long-latency auditory evoked potentials (LLAEP). Results: The pure-tone audiometry identified hearing loss in 13 individuals, and more than 90 % of the hearing loss was sensorineural. The degree of hearing loss was between mild to moderately severe with descendent configuration. Type A tympanogram predominated, and acoustic reflexes were present according to the types and degrees of hearing loss. Among the individuals with abnormal BAEP, longer wave III and V absolute latencies were the main findings. In addition, the unilateral absence of wave I was observed in two cases. In the LLAEP, longer latencies were observed in 14 individuals, and the most impaired components were the P1 and P3 in children and adolescents and the P2, N2 and P3 in adult individuals. Conclusion: The peripheral auditory pathway assessment revealed a predominantly sensorineural hearing loss, affecting mainly high frequencies, and in the central pathway was observed abnormal brainstem and cortical auditory processing in individuals with MPS.
- Long latency auditory evoked potentials in children with cochlear implants: systematic review(2013) SILVA, Liliane Aparecida Fagundes; COUTO, Maria Ines Vieira; MATAS, Carla Gentile; CARVALHO, Ana Claudia Martinho deThe aim of this study was to analyze the findings on Cortical Auditory Evoked Potentials in children with cochlear implant through a systematic literature review. After formulation of research question and search of studies in four data bases with the following descriptors: electrophysiology (eletrofisiologia), cochlear implantation (implante coclear), child (criança), neuronal plasticity (plasticidade neuronal) and audiology (audiologia), were selected articles (original and complete) published between 2002 and 2013 in Brazilian Portuguese or English. A total of 208 studies were found; however, only 13 contemplated the established criteria and were further analyzed; was made data extraction for analysis of methodology and content of the studies. The results described suggest rapid changes in P1 component of Cortical Auditory Evoked Potentials in children with cochlear implants. Although there are few studies on the theme, cochlear implant has been shown to produce effective changes in central auditory path ways especially in children implanted before 3 years and 6 months of age.
- Programa de treinamento auditivo em portadores de zumbido(2016) TUGUMIA, Daniele; SAMELLI, Alessandra Giannella; MATAS, Carla Gentile; MAGLIARO, Fernanda Cristina Leite; RABELO, Camila MaiaABSTRACT 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.
