- 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.
- Caracterização eletrofisiológica da audição em prematuros nascidos pequenos para a idade gestacional(2013) ANGRISANI, Rosanna Mariangela Giaffredo; AZEVEDO, Marisa Frasson de; CARVALLO, Renata Mota Mamede; DINIZ, Edna Maria de Albuquerque; FERRARO, Alexandre Archanjo; GUINSBURG, Ruth; MATAS, Carla GentilePURPOSE: To characterize the Auditory Brainstem Response (ABR) of small for gestational age preterm newborns and to compare the findings to those of appropriate for gestational age premature newborns in order to verify whether the small for gestational age condition is a risk factor for hearing loss. METHODS: This prospective cross-sectional multicenter study evaluated 72 preterm newborns of both genders (35 small and 37 appropriate for gestational age), who were born at 30 to 36 weeks of gestational age and were evaluated before hospital discharge. Only newborns with present transient evoked otoacoustic emissions and tympanometry type A were included. The ABR was performed with click stimuli. The quantitative data analysis was performed using mean and standard deviation measures for each group. For qualitative analysis, the ABR results were classified as normal or altered according to the absolute latencies of waves I, III, V and interpeaks I-III, III-V, I-V. The analysis was carried out considering the age of the newborn at the time of examination. RESULTS: Alterations were evident in 32 newborns (44.44%), being 15 small (43%) and 17 appropriate for gestational age (46%), with no between-groups difference. Of the 15 small for gestational age newborns with altered ABR, six presented as auditory risk only the small for gestational age condition. In the group of adequate for gestational age newborns, there was a higher occurrence of alteration in males. CONCLUSION: There was no difference in responses of auditory evoked potential between small and appropriate for gestational age preterm newborns. Therefore, the condition does not behave as a risk factor for retrocochlear impairment.
- 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.
