- Children with cochlear implants: communication skills and quality of Life(2012) FORTUNATO-TAVARES, Talita; BEFI-LOPES, Debora; BENTO, Ricardo Ferreira; ANDRADE, Claudia Regina Furquim deGiven the multidimensional scope of cochlear implants, there is a growing need to assess clinical measures related communicative abilities and more general aspects involved in the effectiveness of treatment, such as quality of life. Aim: To translate and adapt an international questionnaire of quality of life to Brazilian Portuguese; to apply the questionnaire in parents of children with cochlear implant to assess quality of life of children after cochlear implantation; to analyze correlations among factors related to quality of life; to analyze correlations between quality of life and clinical measures of outcome. Method: prospective study in which parents of children with cochlear implants responded to validated instruments on quality of life and communication abilities. Results: The translation and adaptation of the questionnaire was satisfactorily completed. According to the data, cochlear implants had a positive effect on quality of life of the implanted children and their families. Observed correlations for the variable communication demonstrate a direct relationship between oral communication and other variables of quality of life. Conclusions: This study makes this questionnaire available in Brazilian Portuguese. For parents of Brazilian children with cochlear implants, lexical development(acquisition and use of words) is the variable that relates most to the quality of life of their children.
- Association between language development and auditory processing disorders(2014) ROCHA-MUNIZ, Caroline Nunes; ZACHI, Elaine Cristina; TEIXEIRA, Rosani Aparecida Antunes; VENTURA, Dora Fix; BEFI-LOPES, Debora Maria; SCHOCHAT, ElianeIntroduction: It is crucial to understand the complex processing of acoustic stimuli along the auditory pathway;comprehension of this complex processing can facilitate our understanding of the processes that underlie normal and altered human communication. Aim: To investigate the performance and lateralization effects on auditory processing assessment in children with specific language impairment (SLI), relating these findings to those obtained in children with auditory processing disorder (APD) and typical development (TD). Material and methods: Prospective study. Seventy-five children, aged 6-12 years, were separated in three groups: 25 children with SLI, 25 children with APD, and 25 children with TD. All went through the following tests: speech-in-noise test, Dichotic Digit test and Pitch Pattern Sequencing test. Results: The effects of lateralization were observed only in the SLI group, with the left ear presenting much lower scores than those presented to the right ear. The inter-group analysis has shown that in all tests children from APD and SLI groups had significantly poorer performance compared to TD group. Moreover, SLI group presented worse results than APD group. Conclusion: This study has shown, in children with SLI, an inefficient processing of essential sound components and an effect of lateralization. These findings may indicate that neural processes (required for auditory processing) are different between auditory processing and speech disorders.
- Mismatch negativity in children with specific language impairment and auditory processing disorder(2015) ROCHA-MUNIZ, Caroline Nunes; BEFI-LOPES, Debora Maria; SCHOCHAT, ElianeIntroduction: Mismatch negativity, an electrophysiological measure, evaluates the brain's capacity to discriminate sounds, regardless of attentional and behavioral capacity. Thus, this auditory event-related potential is promising in the study of the neurophysiological basis underlying auditory processing. Objective: To investigate complex acoustic signals (speech) encoded in the auditory nervous system of children with specific language impairment and compare with children with auditory processing disorders and typical development through the mismatch negativity paradigm. Methods: It was a prospective study. 75 children (6-12 years) participated in this study: 25 children with specific language impairment, 25 with auditory processing disorders, and 25 with typical development. Mismatch negativity was obtained by subtracting from the waves obtained by the stimuli /ga/ (frequent) and /da/ (rare). Measures of mismatch negativity latency and two amplitude measures were analyzed. Results: It was possible to verify an absence of mismatch negativity in 16% children with specific language impairment and 24% children with auditory processing disorders. In the comparative analysis, auditory processing disorders and specific language impairment showed higher latency values and lower amplitude values compared to typical development. Conclusion: These data demonstrate changes in the automatic discrimination of crucial acoustic components of speech sounds in children with specific language impairment and auditory processing disorders. It could indicate problems in physiological processes responsible for ensuring the discrimination of acoustic contrasts in pre-attentional and pre-conscious levels, contributing to poor perception.
