Tele-health: assessment of websites on newborn hearing screening in Portuguese Language.

PURPOSE: To verify the aspects of technical quality and the content of websites on neonatal hearing screening in Portuguese. METHODS: Eighteen audiologists, invited to participate according to the inclusion criteria, selected descriptors of websites for research using the Delphi technique. Later, they were fed into Google Trends to get the possible terms to be used by parents in finding information on the Internet about the subject. They were then fed into Google to search the websites. The following assessment instruments were used: list of topics on newborn hearing screening, Flesch Reading Ease Score Formula, Health-Related Web Site Evaluation Emory Form, and PageRank. RESULTS: The most discussed topics in the 19 websites were on the objectives and benefits of neonatal hearing screening, as well as the process of audiological diagnosis. The least discussed were about the false-negative result, development of hearing and language, false-positive results, audiologic, interpretation of results - "Pass"/"Do not pass", retest, and protocol. Difficult reading level was prevalent, with aspects of technical quality considered the best quality-related content, audience, navigation, and structure. The results also showed there is no culture of inserting links on Brazilian national websites, so they had little relevance on Google. CONCLUSIONS: The sites differed in the aspects addressed because there is a need to revise the reading level of the content and quality of the technical aspects regarding the accuracy and timeliness of information, authorship, and links.

Potencial evocado auditivo de longa latência para estímulo de fala apresentado com diferentes transdutores em crianças ouvintes / Late auditory evoked potentials to speech stimuli presented with different transducers in hearing children

Objetivo: analisar, de forma comparativa, a influência do transdutor no registro dos componentes P1, N1 e P2 eliciados por estímulo de fala, quanto à latência e à amplitude, em crianças ouvintes. Método: 30 crianças ouvintes de quatro a 12 anos de idade, de ambos os sexos. Os potenciais evocados auditivos de longa latência foram pesquisados por meio dos transdutores, fone de inserção e caixa acústica, eliciados por estímulo de fala /da/, sendo o intervalo interestímulos de 526ms, a intensidade de 70dBNA e a taxa de apresentação de 1,9 estímulos por segundo. Foram analisados os componentes P1, N1 e P2 quando presentes, quanto à latência e à amplitude. Resultados: constatou-se um nível de concordância forte entre a pesquisadora e o juiz. Não houve diferença estatisticamente significante ao comparar os valores de latência e amplitude dos componentes P1, N1 e P2, ao considerar sexo e orelha, assim como para a latência dos componentes quando analisado os tipos de transdutores. Entretanto, houve diferença estatisticamente significante para a amplitude dos componentes P1 e N1, com maior amplitude para o transdutor caixa acústica. Conclusão: os valores de latência dos componentes P1, N1 e P2 e amplitude de P2 obtidos com fone de inserção podem ser utilizados como referência de normalidade independente do transdutor utilizado para a pesquisa dos potenciais evocados auditivos de longa latência. .

Purpose: to analyze, in a comparative manner, the influence of the transducer on the recordings of P1, N1 and P2components elicited through speech stimulus, as to the latency and amplitude in hearing children. Method: the sample was comprised of 30 hearing children aged 4-12 yrs, both genders. The long latency auditory evoked potentials were researched by means of transducers, insertion phone and speakers, elicited through speech stimulus /da/ presented with interstimuli interval of 526ms, the intensity of 70dBNA and presentation rate of 1.9 stimuli per second. Whenever present, P1, N1 and P2 components were analyzed as to latency and amplitude. Results: it was found a strong level of agreement between the researcher and the judge. There was no statistically significant difference when comparing the values of latency and amplitude of the P1, N1 and P2 components, when considering gender and ear, as well as the latency of components when considering the types of transducers. However, there was a statistically significant difference for the amplitude of the P1 and N1 components with greater amplitude for the speaker transducer. Conclusion: the latency values of the P1, N1 and P2 components and P2 amplitude obtained with insertion phone may be used as normal reference independent of the transducer used for the recording of auditory evoked potentials of long latency. .

Speech perception and cortical auditory evoked potentials in cochlear implant users with auditory neuropathy spectrum disorders.

OBJECTIVE: To characterize the P(1) component of long latency auditory evoked potentials (LLAEPs) in cochlear implant users with auditory neuropathy spectrum disorder (ANSD) and determine firstly whether they correlate with speech perception performance and secondly whether they correlate with other variables related to cochlear implant use. METHODS: This study was conducted at the Center for Audiological Research at the University of São Paulo. The sample included 14 pediatric (4-11 years of age) cochlear implant users with ANSD, of both sexes, with profound prelingual hearing loss. Patients with hypoplasia or agenesis of the auditory nerve were excluded from the study. LLAEPs produced in response to speech stimuli were recorded using a Smart EP USB Jr. system. The subjects' speech perception was evaluated using tests 5 and 6 of the Glendonald Auditory Screening Procedure (GASP). RESULTS: The P(1) component was detected in 12/14 (85.7%) children with ANSD. Latency of the P(1) component correlated with duration of sensorial hearing deprivation (*p=0.007, r=0.7278), but not with duration of cochlear implant use. An analysis of groups assigned according to GASP performance (k-means clustering) revealed that aspects of prior central auditory system development reflected in the P(1) component are related to behavioral auditory skills. CONCLUSIONS: In children with ANSD using cochlear implants, the P(1) component can serve as a marker of central auditory cortical development and a predictor of the implanted child's speech perception performance.

CONCLUSÃO: as emissões otoacústicas evocadas transientes registradas em recém-nascidos a termos e pré-termos apresentam semelhante amplitude absoluta e nível de Response.

PURPOSE: to analyze the absolute amplitude and response level of transient evoked otoacoustic emissions in preterm and full-term newborns. METHODS: 50 full-term and 50 preterm newborns took part in the study. They underwent newborn hearing screening, through research of transient evoked otoacoustic emissions, performed between 24 hours and 11 weeks of life. All newborns showed transient evoked otoacoustic emissions in the newborn hearing screening test. RESULTS: no statistically significant difference of amplitude and response level was found between the full-term and preterm newborns. There was no significant correlation among factors such as prematurity, age of newborn at test and time of hearing stimulation with the results obtained. CONCLUSION: transient evoked otoacoustic emissions recorded in full-term and preterm newborns showed similar absolute amplitude and Response level.

The maturational process of the auditory system in the first year of life characterized by brainstem auditory evoked potentials.

UNLABELLED: The study of brainstem auditory evoked potentials (BAEP) allows obtaining the electrophysiological activity generated in the cochlear nerve to the inferior colliculus. In the first months of life, a period of greater neuronal plasticity, important changes are observed in the absolute latency and inter-peak intervals of BAEP, which occur up to the completion of the maturational process, around 18 months of life in full-term newborns, when the response is similar to that of adults. OBJECTIVE: The goal of this study was to establish normal values of absolute latencies for waves I, III and V and inter-peak intervals I-III, III-V and I-V of the BAEP performed in full-term infants attending the Infant Hearing Health Program of the Speech-Language Pathology and Audiology Course at Bauru School of Dentistry, Brazil, with no risk history for hearing impairment. MATERIAL AND METHODS: The stimulation parameters were: rarefaction click stimulus presented by the 3ª insertion phone, intensity of 80 dBnHL and a rate of 21.1 c/s, band-pass filter of 30 and 3,000 Hz and average of 2,000 stimuli. A sample of 86 infants was first divided according to their gestational age in preterm (n=12) and full-term (n=74), and then according to their chronological age in three periods: P1: 0 to 29 days (n=46), P2: 30 days to 5 months 29 days (n=28) and P3: above 6 months (n= 12). RESULTS: The absolute latency of wave I was similar to that of adults, generally in the 1st month of life, demonstrating a complete process maturity of the auditory nerve. For waves III and V, there was a gradual decrease of absolute latencies with age, characterizing the maturation of axons and synaptic mechanisms in the brainstem level. CONCLUSION: Age proved to be a determining factor in the absolute latency of the BAEP components, especially those generated in the brainstem, in the first year of life.

Potencial cognitivo P300 em indivíduos com diabetes mellitus / Cognitive P300 potential in subjects with diabetes mellitus

Diabetes Mellitus pode acarretar complicacões nos olhos, rins, nervos cranianos, nervos periféricos, ouvidos, etc. A funcão cognitiva também parece estar prejudicada em indivíduos portadores de Diabetes Mellitus, visto que as estruturas corticais e subcorticais responsáveis por esta funcão estão prejudicadas em alguns pacientes dependentes de insulina. O potencial cognitivo P300 tem sido usado como um procedimento objetivo para avaliar a funcão cognitiva cerebral. OBJETIVO: Analisar a sensibilidade do potencial cognitivo P300 para detectar alteracões no córtex auditivo decorrentes do Diabetes Mellitus. FORMA DE ESTUDO: coorte transversal. MATERIAL E MÉTODO: Participaram deste estudo 16 indivíduos diabéticos de ambos os sexos, com idade variando de 7 a 71 anos, e 17 indivíduos não-diabéticos equiparados quanto ao sexo, idade e limiar auditivo. Os procedimentos de avaliacão foram: Audiometria Tonal Liminar (ATL) e potencial cognitivo P300. No grupo diabético foi realizada a medida do valor glicêmico antes da realizacão do P300. RESULTADOS: Os resultados obtidos na ATL não mostraram diferenca estatisticamente significante. Foi observado diferenca estatisticamente significante entre os grupos, quando analisado a latência do componente P3, medido em Fz. Houve correlacão entre a glicemia e a latência e amplitude do P300. CONCLUSAO: A pesquisa do potencial cognitivo P300 é um importante procedimento para prevenir e diagnosticar precocemente de alteracões neurológicas em indivíduos com Diabetes Mellitus.

Cognitive P300 potential in subjects with Diabetes Mellitus.

UNLABELLED: Diabetes Mellitus may lead to alterations in the eyes, kidneys, cranial nerves, peripheral nerves, ears etc. The cognitive function also seems to be compromised in subjects presented with Diabetes Mellitus, since the cortical and subcortical structures responsible for this function are hindered in some insulin-dependent patients. The cognitive potential P300 has been used as an objective procedure to assess cerebral cognitive functions. AIM: To analyze the sensitivity of P300 cognitive potential for the detection of alterations on the auditory cortex secondary to Diabetes Mellitus. STUDY DESIGN: transversal cohort. MATERIAL AND METHOD: Sixteen diabetic subjects of both genders aged 7 to 71 years, and seventeen non-diabetic individuals at the same age range participated in this study. The evaluation procedures were pure tone audiometry (PTA) and P300 cognitive potential. Glycemia of the group presented with Diabetes was assessed prior to applying P300. RESULTS: No statistically significant difference was shown for PTA results. A statically significant difference was observed between groups when analyzing the latency of P300 component measured in Fz. There was a correlation between glycemia and latency and amplitude of P300. CONCLUSION: The investigation of the cognitive potential of P300 is an important procedure for prevention and early diagnosis of neurological changes in individuals presented with Diabetes Mellitus.
