The aim was to describe the outcome of neonatal hearing screening (NHS) and audiological diagnosis in neonates in the NICU. The sample was divided into Group I: neonates who underwent NHS in one step and Group II: neonates who underwent a test and retest NHS. NHS procedure was automated auditory brainstem response. NHS was performed in 82.1% of surviving neonates. For GI, referral rate was 18.6% and false-positive was 62.2% (normal hearing in the diagnostic stage). In GII, with retest, referral rate dropped to 4.1% and false-positive to 12.5%. Sensorineural hearing loss was found in 13.2% of infants and conductive in 26.4% of cases. There was one case of auditory neuropathy spectrum (1.9%). Dropout rate in whole process was 21.7% for GI and 24.03% for GII. We concluded that it was not possible to perform universal NHS in the studied sample or, in many cases, to apply it within the first month of life. Retest reduced failure and false-positive rate and did not increase evasion, indicating that it is a recommendable step in NHS programs in the NICU. The incidence of hearing loss was 2.9%, considering sensorineural hearing loss (0.91%), conductive (1.83%) and auditory neuropathy spectrum (0.19%).

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

RESUMO Objetivo comparar as características clínicas do zumbido e interferência na qualidade de vida em indivíduos com e sem perda auditiva associada, bem como discutir a associação de mensurações quantitativas e instrumentos qualitativos de avaliação. Método estudo quantitativo, descritivo e de corte transversal aprovado pelo Comitê de Ética em pesquisa (nº 973.314/2016 CAEE: 41634815.3.0000.0106). Foram comparadas as respostas da avaliação psicoacústica do zumbido (pesquisa de intensidade, frequência, nível mínimo de mascaramento e limiar de desconforto para tom puro e fala), bem como questionário Tinnitus Handicap Inventory (THI) e escala visual analógica (EVA) de 15 sujeitos portadores de zumbido e perda auditiva periférica (grupo GI) e 16 indivíduos normo-ouvintes (grupo GII). Resultados O escore médio na EVA e THI no GI foi, respectivamente, de 5,1(+1,5) e 42,3(+18) e no GII de 5,7(+2.6) e 32,7(+25), sugerindo incômodo moderado no GI e moderado/leve no GII (p>0,005). Verificou-se correlação moderada entre o THI e EVA apenas no GII. Na avaliação psicoacústica, observaram-se diferenças significantes entre os grupos referentes à medida da loudness (*p=0,013) e ao nível mínimo de mascaramento (*p=0,001). Conclusão a perda auditiva parece não se constituir em um fator determinante para o maior ou menor impacto do zumbido na qualidade de vida do sujeito. Já as diferenças encontradas entre os grupos, referentes às medidas psicoacústicas, podem ser justificadas pela presença do dano coclear em si. A mensuração objetiva do zumbido, independentemente da presença ou não da perda auditiva periférica, caracteriza-se como um importante instrumento complementar às medidas de auto avaliação.

The aim of this research was to analyze temporal auditory processing and phonological awareness in school-age children with benign childhood epilepsy with centrotemporal spikes (BECTS). Patient group (GI) consisted of 13 children diagnosed with BECTS. Control group (GII) consisted of 17 healthy children. After neurological and peripheral audiological assessment, children underwent a behavioral auditory evaluation and phonological awareness assessment. The procedures applied were: Gaps-in-Noise test (GIN), Duration Pattern test, and Phonological Awareness test (PCF). Results were compared between the groups and a correlation analysis was performed between temporal tasks and phonological awareness performance. GII performed significantly better than the children with BECTS (GI) in both GIN and Duration Pattern test (P < 0.001). GI performed significantly worse in all of the 4 categories of phonological awareness assessed: syllabic (P = 0.001), phonemic (P = 0.006), rhyme (P = 0.015) and alliteration (P = 0.010). Statistical analysis showed a significant positive correlation between the phonological awareness assessment and Duration Pattern test (P < 0.001). From the analysis of the results, it was concluded that children with BECTS may have difficulties in temporal resolution, temporal ordering, and phonological awareness skills. A correlation was observed between auditory temporal processing and phonological awareness in the suited sample.
