- 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.
- 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.
- Translation and cross-cultural adaptation of the Noise Exposure Questionnaire (NEQ) to Brazilian Portuguese(2023) OLIVEIRA, Leticia Campos de; ROCHA, Clayton Henrique; MATAS, Carla Gentile; PAIVA, Karina Mary de; MOREIRA, Renata Rodrigues; SAMELLI, Alessandra GiannellaObjective: To translate and cross-culturally adapt the Noise Exposure Questionnaire (NEQ) and 1-Minute Noise Screen (NEQ-S) instruments to Brazilian Portuguese. Methods: Procedures widely known in health research were used in the translation and cross-cultural adaptation process, comprising the following steps: initial translation, synthesis of translations, back-translation, expert committee, pretest, and content and layout validation. Altogether, 60 workers participated in the pretest by answering the questionnaires and then evaluating them in terms of understandability, layout, clarity, and writing. Reliability was verified with Cohen's kappa test, and the internal consistency was analyzed with Cronbach's alpha coefficient. Results: The translated and adapted versions of NEQ and NEQ-S were similar in terms of general and referential meanings. However, some modifications and adaptations were made to adapt them to the Brazilian reality. The kappa test indicated moderate agreement and Cronbach's alpha coefficient, substantial internal consistency. Conclusion: The translation and cross-cultural adaptation were carried out according to the methodology recommended in the national and international literature, performing the necessary equivalences to maintain the face and content validity with the original instrument. The availability of NEQ and NEQ-S in Brazilian Portuguese opens new fields of research to quantify yearly noise exposure more in-depth.
- 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 GentilePurpose 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.
- Effects of diabetes mellitus and systemic arterial hypertension on elderly patients' hearing(2018) ROLIM, Laurie Penha; SAMELLI, Alessandra Giannella; MOREIRA, Renata Rodrigues; MATAS, Carla Gentile; SANTOS, Itamar de Souza; BENSENOR, Isabela Martins; LOTUFO, Paulo AndradeIntroduction: Chronic diseases can act as an accelerating factor in the auditory system degeneration. Studies on the association between presbycusis and diabetes mellitus and systemic arterial hypertension have shown controversial conclusions. Objective: To compare the initial audiometry (A1) with a subsequent audiometry (A2) performed after a 3 to 4-year interval in a population of elderly patients with diabetes mellitus and/or systemic arterial hypertension, to verify whether hearing loss in these groups is more accelerated when compared to controls without these clinical conditions. Methods: 100 elderly individuals participated in this study. For the auditory threshold assessment, a previous complete audiological evaluation (A1) and a new audiological evaluation (A2) performed 3-4 years after the first one was utilized. The participants were divided into four groups: 20 individuals in the diabetes mellitus group, 20 individuals in the systemic arterial hypertension group, 20 individuals in the diabetes mellitus/systemic arterial hypertension group and 40 individuals in the control group, matching them with each study group, according to age and gender. ANOVA and Kruskal-Wallis statistical tests were used, with a significance level set at 0.05. Results: When comparing the mean annual increase in the auditory thresholds of the A1 with the A2 assessment, considering each study group and its respective control, it can be observed that there was no statistically significant difference for any of the frequencies for the diabetes mellitus group; for the systemic arterial hypertension group, significant differences were observed after 4 kHz. For the diabetes mellitus and systemic arterial hypertension group, significant differences were observed at the frequencies of 500, 2 kHz, 3 kHz and 8 kHz. Conclusion: It was observed that the systemic arterial hypertension group showed the greatest decrease in auditory thresholds in the studied segment when compared to the other groups, suggesting that among the three studied conditions, hypertension seems to have the greatest influence on hearing.

- A longitudinal study of the peripheral and central auditory pathways in individuals with acute lymphoid leukemia(2023) VOSGRAU, Jessica Sales; SILVA, Liliane Aparecida Fagundes; FILHO, Vicente Odone; MATAS, Carla GentileObjective: To characterize the peripheral and central auditory pathways in individuals with Acute Lymphoid Leukemia (ALL) and compare assessment results before and during chemotherapy. Method: The study included 17 subjects with ALL, divided into two age groups: 3 to 6 (11 individuals) and 7 to 16 years old (6 individuals). Each subject was evaluated twice (before and 3 to 6 months after chemotherapy treatment) with the following procedures: medical history survey, otoscopy, Pure-Tone Threshold (PTA) and speech audiometry, acoustic immittance measures, Brainstem Auditory Evoked Potentials (BAEP) and LongLatency Auditory Evoked Potentials (LLAEP).Results: PTA was normal. Tympanometry was abnormal in the second assessment in 2 individuals aged 3 to 6 years. One subject in each age group had absent ipsilateral acoustic reflexes. In high-frequency audiometry, 1 individual had abnormal results. BAEP was abnormal in 5 (first assessment) and 7 individuals (second assessment) aged 3 to 6 years and 2 (first assessment) and 1 individual (second assessment) aged 7 to 16 years. As for LLAEP, P1 latency was increased in 5 (first assessment) and 7 individuals (second assessment) aged 3 to 6 years.Conclusion: No hearing loss was identified in the behavioral audiological assessment. BAEP was more affected in the 3-to-6-year-old group, with greater impairment in the lower brainstem in the first and second assessments. In LLAEP, P1 was the most impaired component in children aged 3 to 6 years, and P2 and N2 were so for those 7 to 16 years old, especially in the second assessment.
- 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.
- 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 DiasAbstract 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.
- Plasticidade neuronal da via auditiva em crianças com transtorno dos sons da fala: estudo dos Potenciais Evocados Auditivos de Longa Latência(2021) LUNA, Amanda Cristina; SILVA, Liliane Aparecida Fagundes; BARROZO, Tatiane Faria; LEITE, Renata Aparecida; WERTZNER, Haydée Fiszbein; MATAS, Carla GentileAbstract Purpose To analyze the results of Long-latency Auditory Evoked Potentials (LLAEP) in children with Speech Sounds Disorder (SSD) after speech therapy. Methods Longitudinal and prospective clinical study at 14 children with SSD, with ages ranging from five to seven years, of both genders. Were applied Picture Naming task and Imitation task, and from these tasks it was calculated the Percentage of Consonants Correct index. For an analysis of the LLAEP with speech stimulus and recorded the latency and amplitude values of P1, N1, P2, N2 and P3 components. Each child was evaluated in two different moments: initial evaluation and after 12 sessions of speech therapy. Results It was observed that after twelve sessions of speech therapy the value of Percentage of Consonants Correct index increased, and a greater number of components were observed in the LLAEP records of children with SSD, as well as a statistically significant increase in the amplitude of the P3 component, demonstrating that anatomical and physiological changes occurred in the central auditory nervous system after intervention, resulting in improved of the LLAEP results. Conclusion After speech therapy, improvement in the children's phonology was observed, and there was an increase in the number of components present in the LLAEP, as well as an increase in the amplitude of the P3 component, demonstrating that plasticity occurred in the auditory pathway during these three months of therapeutic intervention.
