- Efferent inhibition of otoacoustic emissions in preterm neonates(2015) CARVALLO, Renata Mota Mamede; SANCHES, Seisse Gabriela Gandolfi; IBIDI, Silvia Maria; SOARES, Jordana Costa; DURANTE, Alessandra SpadaIntroduction: Abnormalities in auditory function of newborns may occur not only because of preterm birth, but also from the use of medications and from diseases related to prematurity. Objective: To analyze the inhibitory effect from stimulation of the olivocochlear efferent system on transient evoked otoacoustic emissions in preterm neonates, comparing these data with those from full-term neonates. Methods: This was a prospective, cross-sectional, contemporary cohort study with 125 neonates, pooled into two groups: full-term (72 full-term neonates, 36 females and 36 males, born at 37-41 weeks of gestational age); and preterm (53 neonates, 28 males and 25 females, born at <= 36 weeks of gestational age, evaluated at the corrected gestational age of 37-41 weeks). Otoacoustic emissions were recorded using linear and nonlinear click-evoked stimuli, with and without contralateral stimulation. Results: The inhibitory effect of the efferent pathway in otoacoustic emissions was different (p = 0.012) between groups, and a mean reduction of 1.48 dB SPL in full-term births and of 1.02 dB SPL in preterm births was observed for the non-linear click-evoked stimulus. Conclusion: The results suggest a reduced inhibitory effect of the olivocochlear efferent system on otoacoustic emissions in preterm neonates.
- Middle ear muscle reflex measurement in neonates: Comparison between 1000 Hz and 226 Hz probe tones(2015) LYRA-SILVA, Kilza Arruda de; SANCHES, Seisse Gabriela Gandolfi; NEVES-LOBO, Ivone Ferreira; IBIDI, Silvia Maria; CARVALLO, Renata Mota MamedeIntroduction: Middle ear muscle reflex (MEMR) evaluation assists in diagnosing hearing problems because normal responses depend on preconditions of a healthy auditory system. Studies in neonates recording the acoustic reflex with 226 Hz probes have described high rates of absence. Other studies using a high frequency probe have found higher rates of presence in normal neonates. However, few studies have compared results between low and high frequency probes in the same newborns. Objective: To comparatively assess the ipsilateral acoustic reflex recorded by 226 Hz and 1000 Hz probes in newborns. Method: A total of 77 newborns, with the presence of transient otoacoustic emissions, underwent tympanometry, wideband acoustic immittance, and ipsilateral reflex investigations with 226 Hz and 1000 Hz tone probes. Results: The acoustic reflex was activated at a much lower intensity with all activating stimuli using the 1000 Hz probe compared with the values of the 226 Hz probe. There was a higher incidence of ipsilateral acoustic reflexes recorded by the 1000 Hz tone probe compared to the 226 Hz tone probe. There was no correlation between the acoustic reflex thresholds and otoacoustic emissions. Conclusion: In newborns, the acoustic reflex measurements obtained with the 1000 Hz probe showed advantages over the 226 Hz probe.
- Reflectância de banda larga em recém-nascidos com presença de emissões otoacústicas evocadas por transiente(2013) SILVA, Kilza Arruda de Lyra e; UROSAS, Juliana Granja; SANCHES, Seisse Gabriela Gandolfi; CARVALLO, Renata Mota MamedePURPOSE: To characterize the normal values of acoustic energy reflectance obtained with pure-tone stimulation in neonates prior to hospital discharge. METHODS: Seventy-seven infants (37 girls and 40 boys) were evaluated by measuring acoustic reflectance using pure-tone stimuli, transient-evoked otoacoustic emissions, and tympanometric probe frequencies of 226 Hz and 1 kHz. RESULTS: At low frequencies (258-750 Hz), greater energy reflectance was observed, while at medium frequencies (1-3 kHz), greater energy absorption was observed. There was no difference between ears or between genders. CONCLUSION: Normal energy reflectance values were obtained for the studied population. The data indicate a reflectance curve with a distinct configuration for the studied age.
- 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.
- Severe obstructive sleep apnea is associated with cochlear function impairment(2018) MATSUMURA, Erika; MATAS, Carla G.; SANCHES, Seisse G. G.; MAGLIARO, Fernanda C. L.; PEDRENO, Raquel M.; GENTA, Pedro R.; LORENZI-FILHO, Geraldo; CARVALLO, Renata M. M.The purpose of this study is to investigate the association between obstructive sleep apnea (OSA) with middle ear acoustic transference and cochlear function. Male individuals with and without mild, moderate, and severe OSA according to standard criteria of full polysomnography and no co-morbidities were studied. Subjects with BMI 40 kg/m(2), present or past treatment for OSA, with heart failure, diabetes, hypertension, dyslipidemia, stroke, use of chronic medications, and previous history of risk for hearing loss were excluded. All subjects were submitted to full polysomnography, evaluation of wideband acoustic immittance by energy of absorbance (EA), and distortion product otoacoustic emissions (DPOAE). We studied 38 subjects (age 35.8 +/- 7.2 years, BMI 28.8 +/- 3.8 kg/m(2)) divided into no OSA (n = 10, age 33.6 +/- 6.4 years, BMI 26.9 +/- 4.1 kg/m(2)), mild (n = 11, age 32.8 +/- 2.9 years, BMI 28.5 +/- 3.5 kg/m(2)), moderate (n = 8, age 34.1 +/- 6.8 years, BMI 29.6 +/- 3.3 kg/m(2)), and severe OSA (n = 9, age 41.2 +/- 9.2 years, BMI 30.5 +/- 3.8 kg/m(2)). EA was similar between groups. In contrast, patients with severe OSA presented significantly lower DPOAE amplitudes when compared to the control, mild, and moderate OSA groups (p ae 0.03, for all comparisons). Acoustic transference function of middle ear is similar in adults with and without OSA. Severe OSA is independently associated with cochlear function impairment in patients with no significant co-morbidities.
- Processamento temporal de crianças com transtorno fonológico submetidas ao treino auditivo: estudo piloto(2012) VILELA, Nadia; WERTZNER, Haydée Fiszbein; SANCHES, Seisse Gabriela Gandolfi; NEVES-LOBO, Ivone Ferreira; CARVALLO, Renata Mota MamedePURPOSE: This study compared the temporal processing performance of children with phonological disorders submitted to formal and informal auditory training. METHODS: Fifteen subjects with phonological disorder (pure tone thresholds ≤20 dBHL from 0.50 to 4 kHz, and age between 7 years and 10 years and 11 months) were evaluated, divided into three groups: Control Group: five subjects (mean age 9.1 years) without auditory processing disorder, who passed through two evaluations of the auditory processing at intervals of six to eight weeks and without any intervention; Formal Training Group with five subjects (average 8.3 years) with auditory processing disorder submitted to eight sessions of formal training; and Informal Training Group, with five subjects (average 8.1 years) with auditory processing disorder submitted to eight sessions of informal training. RESULTS: After eight sessions the formal training group showed an improvement of 8% and the informal training group of 22.5% in comparison with the pitch pattern sequence test. For the duration pattern sequence test, the average of the formal training group improved by 12.9% and the informal training group by 18.7%. There was no statistical difference between the means obtained by both groups after intervention, neither in the pitch pattern nor in the duration pattern sequence test. CONCLUSION: Although the results did not present significant differences, this pilot study suggests that both formal and informal trainings provide improvement in the temporal processing abilities of children with phonological and auditory processing disorders.
- Teleaudiometry as a screening method in school children(2015) BOTASSO, Maine; SANCHES, Seisse Gabriela Gandolfi; BENTO, Ricardo Ferreira; SAMELLI, Alessandra GiannellaOBJECTIVE: To compare the efficacy and feasibility of teleaudiometry with that of sweep audiometry in elementary school children, using pure-tone audiometry as the gold standard. METHODS: A total of 243 students with a mean age of 8.3 years participated in the study. Of these, 118 were boys, and 125 were girls. The following procedures were performed: teleaudiometry screening with software that evaluates hearing at frequencies of 1,000, 2000 and 4000 Hz at 25 dBHL; sweep audiometry screening in an acoustic booth (20 dBHL at the same frequencies); pure-tone audiometry thresholds in an acoustic booth (frequencies of 500, 1000, 2000 and 4000 Hz); and acoustic immittance measurements. RESULTS: The diagnostic capacities of the teleaudiometry/sweep audiometry screening methods were as follows: sensitivity ϝ 58%/65%; specificity ϝ 86%/99%; positive predictive value ϝ 51%/91%; negative predictive value ϝ 89%/92%; and accuracy ϝ 81%/92%. Teleaudiometry and sweep audiometry showed moderate agreement. Furthermore, the use of these methods in series with immittance testing improved the specificity, whereas parallel testing improved the sensitivity. CONCLUSION: Teleaudiometry was found to be reliable and feasible for screening hearing in school children. Moreover, teleaudiometry is the preferred method for remote areas where specialized personnel and specific equipment are not available, and its use may reduce the costs of hearing screening programs.
- Processamento temporal e consciência fonológica nas alterações de leitura e escrita: dados preliminares(2013) SOARES, Aparecido José Couto; SANCHES, Seisse Gabriela Gandolfi; ALVES, Débora Cristina; CARVALLO, Renata Mota Mamede; CÁRNIO, Maria SilviaPURPOSE: To verify if there is an association between temporal auditory tests and phonological awareness in individuals with reading and writing disorders. METHODS: Sixteen children were subjects of this study, aged between 7 and 12 years old, who had reading and writing disorders confirmed after specific assessment. All participants underwent phonological awareness assessment using CONFIAS test. In order to assess the auditory temporal processing, duration and frequency pattern tests were used. RESULTS: The descriptive analysis indicated low performance in syllabic and phonemic activities of phonological awareness as well as in temporal auditory tests. Fisher's test indicated association between disorders in auditory temporal processing and phonological awareness (p>0.001). It suggests that disorders in temporal processing contribute to low performance in phonological awareness tasks. CONCLUSIONS: There was association between performance in temporal auditory tests and in the phonological awareness. Data found provide reflections about including temporal auditory assessment among procedures used in the analysis of individuals with reading and writing disorders.
