Objective: Investigate the prevalence of hearing impairment in newborns hospitalized at the Intensive and Intermediate Care Unit at the Womens Comprehensive Health Center Neonatology Service (UNICAMP) and associated risk factors.Methods: 979 newborn babies were assessed between January 2000 and January 2003, through automated auditory brainstem response (AABR) (ALGO 2e color screener). The result was considered normal when the newborn showed response to a 35dBNA signal bilaterally. The prevalence of AABR impairment and the odds ratio were analyzed with a 95% confidence interval using bivariate analysis. To identify the independent risk factors for hearing alterations, multivariate analyses were used with logistic regression.Results: The prevalence of AABR impairment was 10.2%, of which 5.3% was unilateral and 4.9% bilateral. From the multivariate analyses, the following observations were made: family history of congenital hearing loss (OR = 5.192; p = 0.016), craniofacial deformity (OR = 5.530; p < 0.001), genetic syndromes associated with hearing loss (OR = 4.212; p < 0.001), weight below 1,000 g (OR = 3.230; p < 0.001), asphyxia (OR = 3.532; p < 0.001), hyperbilirubinemia (OR = 4.099; p = 0.002) and use of mechanical ventilation (OR = 1.826; p < 0.031) were the indicators that best characterized the group at risk for hearing impairment. Conclusions:The prevalence of hearing impairment using AABR is high. Therefore, it is essential for all newborns who present isolated or associated risk factors to undergo hearing screening in situations in which it is not possible to have universal hearing screening.J Pediatr (Rio J). 2006;82(2):110-4: Newborn, diagnosis, hearing loss. ResumoObjetivo: Avaliar a prevalência de alterações auditivas em recém-nascidos internados na unidade de terapia intensiva e cuidados intermediários do serviço de neonatologia do Centro de Assistência Integral à Saúde da Mulher, Faculdade de Ciências Médicas, Universidade Estadual de Campinas, e analisar os fatores de risco associados.Métodos: Foram avaliados 979 recém-nascidos no período de janeiro de 2000 a janeiro de 2003, utilizando-se a audiometria automá-tica de tronco encefálico (AABR), com aparelho ALGO-2e color -Natus. O resultado foi considerado normal quando o recém-nascido apresentou resposta para 35 dBNA bilateralmente. Foi analisada a prevalência de AABR alterada e odds ratio com intervalo de confiança de 95% em análise bivariada. Para identificar os fatores de risco independentes para AABR alterada, foi feita análise múltipla com modelo de regressão logística.Resultados: A prevalência de alteração no AABR foi de 10,2%, sendo 5,3% unilateral e 4,9% bilateral. Pela análise multivariada, observamos que: antecedente familiar (OR = 5,192; p = 0,016), malformação craniofacial (OR = 5,530; p < 0,001), síndrome genética (OR = 4,212; p < 0,001), peso menor que 1.000 g (OR = 3,230; p < 0,001), asfixia (OR = 3,532; p < 0,001), hiperbilirrubinemia (OR = 4,099; p = 0,002) e uso de ventilação mecânica (OR = 1,826; p < 0,031) foram os in...

Chi ldren with cleft lip/palate often present otitis media as a result of anatomic and/or functional alterations of the Eustachian tube. Aim: to analyze the results of Basic Audiologic Evaluation (BAE) and Auditory Processing Screening (APS) in children with cleft lip/palate. Study design: prospective cross-sectional cohort. Materials and methods: Forty-four male and female children, within the 8 to 14 age range with non-syndromic cleft lip/palate, referred by the institution where the study was carried out. The BAE was made up by an interview, otoscopy, threshold tonal audiometry, logoaudiometry and impedance test. The APS was made up of 3 basic tests: Sound Localization Test, Sequential Memory for verbal and non-verbal sounds and Dichotic Listening Test. Results: The BAE revealed that 77.27% of the children presented normal hearing; 13.6% had conductive hearing loss and 2.2% presented mixed hearing loss. 21.2% of the children had type C tympanometry curve; 7.1% had a type B curve and 3.5% had an Ad curve. The APS was altered in 72.7% of the children and 45.5% of them presented altered results on the Dichotic Listening Test. Conclusion: children with cleft lip/palate had altered results on BAE and APS, which justifies audiological and medical follow-up.

Aim:To compare ABR responses in full-term and premature infants; gender and ear were taken into account. Methods:A cross-sectional prospective cohort study was carried out. We evaluated 36 full-term and 30 premature infants that had passed the Transient Otoacoustic Emissions test, had type A tympanometric curves, and had no risk factor for hearing loss besides prematurity. The evaluations were done from the time of hospital discharge to the third month of life, and consisted of a clinical history, acoustic immittance testing and ABR evaluation. Results:The comparison of absolute and interpeak wave I, III and V latencies in right and left ears revealed a statistically significant difference at the interpeak I-III. There was no significant gender differences in the comparison of results. Significant difference in wave I, III and V absolute latencies at 80 dB and in wave V at 60 db and 20 db were observed in a comparison of absolute and interpeak latencies between full-term and premature infants. An inverse correlation was found between age and absolute latencies. Conclusions:The maturity of the auditory system influences ABR responses in infants. To avoid misinterpretation of results, gestational age must be taken into account in the analysis of ABR in pediatric population. Braz J Otorhinolaryngol. 2010;76(6):729-38. ORIGINAL ARTICLE BJORL

OBJETIVO: Analisar os resultados obtidos na triagem auditiva neonatal realizada por meio de dois procedimentos, Emissões Otoacústicas Transientes e Potencial Evocado Auditivo de Tronco Encefálico - modo automático, em uma população de neonatos saudáveis de um hospital público, considerando-se o gênero masculino e feminino e o lado em que a falha ocorreu. MÉTODOS: Foram incluídos na pesquisa neonatos de alojamento conjunto, nascidos em um hospital público, e que realizaram triagem auditiva após a alta hospitalar. Utilizou-se para triagem as Emissões Otoacústicas Transientes (EOAT) com critério passa/falha e o reteste com o Potencial Evocado Auditivo de Tronco Encefálico-modo automático (PEATE-A). RESULTADOS: Foram testados 5106 neonatos, 51,3% do sexo masculino e 48,7% do sexo feminino. Falharam 628 (12,3%) neonatos, 368 (58,6%) do sexo masculino e 260 (41,4%) do gênero feminino, sendo encaminhados para o PEATE-A. Destes, 223 (35,3%) compareceram ao exame, 199 (89,2%) passaram e 24 (10,8%) falharam; 17 (70,9%) do gênero masculino e sete (29,1%) do gênero feminino. Houve diferença estatística significante entre falha auditiva por meio das emissões otoacústicas e sexo. Encontrou-se 10% de neonatos que falharam nos dois procedimentos de triagem. CONCLUSÃO: Encontrou-se um número maior de falhas em crianças do gênero masculino no teste de emissões otoacústicas transientes. Não houve diferença entre neonatos do gênero masculino ou feminino quanto às falhas nas orelhas esquerda e direita.
