- 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.
- Fatores que influenciam na participação dos pais de crianças usuárias de implante coclear na (re)habilitação oral: revisão sistemática(2013) COUTO, Maria Inês Vieira; CARVALHO, Ana Claudia MartinhoPURPOSE: To identify and analyze factors that influence the participation of parents in the rehabilitation process of children with cochlear implants (CI). RESEARCH STRATEGY: Question formulation and articles selection in three databases using the following keywords: cochlear implant (implante coclear) and parents (pais). SELECTION CRITERIA: Complete original articles published in Brazilian Portuguese or English, with direct participation of parents of children with CI. DATA ANALYSIS: Articles were fully read. Data regarding characterization of the centers, research methodology and content were analyzed. RESULTS: Thirteen articles were selected based on the established criteria. The types of studies were cross-sectional and case-control (interview technique). The following influential factors were identified: pre-CI surgery factors (knowledge about CI, quality and quantity of information, specialist's advices, ethical and biomedical aspects, rehabilitation engagement, contact with experienced families, social service support and overall costs); rehabilitation aspects (CI use, oral communication modality, regular school, other disabilities, social and demographic aspects and rehabilitation program's effectiveness); other important influential processes (communication modality, auditory and language development, second oral language learning, as well as parent's behavior and satisfaction). CONCLUSION: The engagement of parents in the rehabilitation process of children with CI depends on several distinct influential factors which audiologists should understand and consider when elaborating a rehabilitation program.
- Long latency auditory evoked potentials in children with cochlear implants: systematic review(2013) SILVA, Liliane Aparecida Fagundes; COUTO, Maria Ines Vieira; MATAS, Carla Gentile; CARVALHO, Ana Claudia Martinho deThe aim of this study was to analyze the findings on Cortical Auditory Evoked Potentials in children with cochlear implant through a systematic literature review. After formulation of research question and search of studies in four data bases with the following descriptors: electrophysiology (eletrofisiologia), cochlear implantation (implante coclear), child (criança), neuronal plasticity (plasticidade neuronal) and audiology (audiologia), were selected articles (original and complete) published between 2002 and 2013 in Brazilian Portuguese or English. A total of 208 studies were found; however, only 13 contemplated the established criteria and were further analyzed; was made data extraction for analysis of methodology and content of the studies. The results described suggest rapid changes in P1 component of Cortical Auditory Evoked Potentials in children with cochlear implants. Although there are few studies on the theme, cochlear implant has been shown to produce effective changes in central auditory path ways especially in children implanted before 3 years and 6 months of age.
- Maturação dos potenciais evocados auditivos de longa latência em crianças ouvintes: revisão sistemática(2017) SILVA, Liliane Aparecida Fagundes; MAGLIARO, Fernanda Cristina Leite; CARVALHO, Ana Claudia Martinho de; MATAS, Carla GentileABSTRACT Purpose To analyze how Auditory Long Latency Evoked Potentials (LLAEP) change according to age in children population through a systematic literature review. Research strategies After formulation of the research question, a bibliographic survey was done in five data bases with the following descriptors: Electrophysiology (Eletrofisiologia), Auditory Evoked Potentials (Potenciais Evocados Auditivos), Child (Criança), Neuronal Plasticity (Plasticidade Neuronal) and Audiology (Audiologia). Selection criteria Level 1 evidence articles, published between 1995 and 2015 in Brazilian Portuguese or English language. Data analysis Aspects related to emergence, morphology and latency of P1, N1, P2 and N2 components were analyzed. Results A total of 388 studies were found; however, only 21 studies contemplated the established criteria. P1 component is characterized as the most frequent component in young children, being observed around 100-150 ms, which tends to decrease as chronological age increases. The N2 component was shown to be the second most commonly observed component in children, being observed around 200-250 ms.. The other N1 and P2 components are less frequent and begin to be seen and recorded throughout the maturational process. Conclusion The maturation of LLAEP occurs gradually, and the emergence of P1, N1, P2 and N2 components as well as their latency values are variable in childhood. P1 and N2 components are the most observed and described in pediatric population. The diversity of protocols makes the comparison between studies difficult.
- Maturação dos potenciais evocados auditivos de longa latência em crianças ouvintes: análise do complexo P1-N1-P2-N2(2017) SILVA, Liliane Aparecida Fagundes; MAGLIARO, Fernanda Cristina Leite; CARVALHO, Ana Claudia Martinho de; MATAS, Carla GentileABSTRACT Purpose The purpose of this study was to monitor the emergence and changes to the components of the Long Latency Auditory Evoked Potentials (LLAEP) in normal hearing children. Methods This longitudinal study included children of both genders: seven aged between 10 and 35 months, and eight children between 37 and 63 months. The electrophysiological hearing evaluation consisted of analysis of LLAEP obtained in a sound field generated with loudspeakers positioned at an azimuth of 90°, through which the syllable /ba/ was played at an intensity of 70 dB HL. Each child underwent an initial evaluation followed by two re-evaluations three and nine months later. Results The emergence of LLAEP components across the nine-month follow-up period was observed. P1 and N2 were the most common components in children of this age range. There was no statistically significant difference regarding the occurrence of P1, N1, P2, and N2 components amongst younger and older children. Regarding latency values, the greatest changes overtime were observed in the P1 component for younger children and in the N2 component for older children. Only the P1 component significantly differed between the groups, with the highest latency values observed in younger children. Conclusion LLAEP maturation occurs gradually and the emergence of complex components appears to be related more to the maturation of the central auditory nervous system than to chronological age.
- Nijmegen Cochlear Implantation Questionnaire (NCIQ): tradução, adaptação cultural e aplicação em adultos usuários de implante coclear(2017) SANTOS, Nathália Porfírio dos; COUTO, Maria Inês Vieira; MARTINHO-CARVALHO, Ana ClaudiaABSTRACT Purpose Cross-cultural adaptation and translation of the Nijmegen Cochlear Implant Questionnaire (NCIQ) into Brazilian Portuguese and analysis of quality of life (QoL) results in adults with cochlear implant (CI). Methods The NCIQ instrument was translated into Brazilian Portuguese and culturally adapted. After that, a cross-sectional and clinical QoL evaluation was conducted with a group of 24 adults with CI. Results The questionnaire title in Brazilian Portuguese is ‘Questionário Nijmegen de Implantes Cocleares’ (NCIQ-P). The version of the NCIQ questionnaire translated into Brazilian Portuguese presented good internal consistency (0.78). The social and physical domains presented the highest scores, with the basic and advanced sound perception subdomains achieving the highest scores. No correlation between gender and time of device use was found for the questionnaire domains and subdomains. Conclusion The cross-cultural adaptation and translation of the NCIQ into Brazilian Portuguese suggests that this instrument is reliable and useful for clinical and research purposes in Brazilian adults with CI.
