- Audiological manifestations in HIV-positive adults(2014) MATAS, Carla Gentile; ANGRISANI, Rosanna Giaffredo; MAGLIARO, Fernanda Cristina Leite; SEGURADO, Aluisio Augusto CotrimOBJECTIVE: 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.
- Avaliação auditiva periférica em crianças com síndrome de Down(2014) CARRICO, Barbara; SAMELLI, Alessandra Giannella; MATAS, Carla Gentile; MAGLIARO, Fernanda Cristina Leite; CARVALLO, Renata Mota Mamede; LIMONGI, Suelly Cecília Olivan; NEVES-LOBO, Ivone FerreiraPurpose This study sought to characterize the peripheral auditory system of individuals with Down syndrome (DS) using conventional and high-frequency audiometry. Methods We performed a cross-sectional and observational study. Fifteen individuals with DS, who were of both genders and between 7 and 15 years of age, participated in this study. The following procedures were performed: otoscopy, tympanometry with ipsilateral and contralateral acoustic reflex, pure-tone audiometry, vocal audiometry and high-frequency audiometry. Results There was a predominance of mild conductive hearing loss in one or both ears. The mean hearing thresholds for conventional audiometry were below 20 dB HL and between 20 and 40 dB HL for high-frequency audiometry. The Pearson correlation coefficient indicated a moderate positive correlation between the 9-14 kHz thresholds and age. Conclusion Overall, no significant differences were observed when comparing the right and left ears of individuals with DS, in regards to pure-tone audiometry, immittance testing and speech audiometry. Most children showed middle ear abnormalities and conductive hearing loss. Moreover, high-frequency audiometry suggested the onset of impaired cochlear function, which may be associated with frequent otitis media episodes and/or early cochlear degeneration.
- Auditory evoked potentials: predicting speech therapy outcomes in children with phonological disorders(2014) LEITE, Renata Aparecida; WERTZNER, Haydee Fiszbein; GONCALVES, Isabela Crivellaro; MAGLIARO, Fernanda Cristina Leite; MATAS, Carla GentileOBJECTIVES: This study investigated whether neurophysiologic responses (auditory evoked potentials) differ between typically developed children and children with phonological disorders and whether these responses are modified in children with phonological disorders after speech therapy. METHODS: The participants included 24 typically developing children (Control Group, mean age: eight years and ten months) and 23 children clinically diagnosed with phonological disorders (Study Group, mean age: eight years and eleven months). Additionally, 12 study group children were enrolled in speech therapy (Study Group 1), and 11 were not enrolled in speech therapy (Study Group 2). The subjects were submitted to the following procedures: conventional audiological, auditory brainstem response, auditory middle-latency response, and P300 assessments. All participants presented with normal hearing thresholds. The study group 1 subjects were reassessed after 12 speech therapy sessions, and the study group 2 subjects were reassessed 3 months after the initial assessment. Electrophysiological results were compared between the groups. RESULTS: Latency differences were observed between the groups (the control and study groups) regarding the auditory brainstem response and the P300 tests. Additionally, the P300 responses improved in the study group 1 children after speech therapy. CONCLUSION: The findings suggest that children with phonological disorders have impaired auditory brainstem and cortical region pathways that may benefit from speech therapy.
