ABSTRACT Purpose To describe the panorama of children's hearing health in the Unified Health System of the state of Sergipe. Methods A quantitative and retrospective study consisting of four steps: 1) Search the National Registry of Health Establishments of institutions affiliated to the Health Unic System in the state of Sergipe that perform obstetric services and hearing health services; 2) Collecting Neonatal Hearing Screening (NHS) coverage data through DATASUS (from 2012 to 2020); 3) Data collection from medical records of institutions with obstetrics and that perform NHS; and 4) Interview with the guardians of children undergoing auditory rehabilitation. The results were summarized using descriptive statistics (absolute and relative frequency, measures of central tendency, and dispersion). Results Only one out of the 29 establishments with obstetrics performs NHS. Two of the Hearing Health Reference Centers (HHRC) are qualified for cochlear implants and two Specialized Centers are qualified for Rehabilitation. From 2012 to 2020, NHS coverage in the state was less than 40%, and when performed in the maternity ward, there were no referrals for Brainstem Auditory Evoked Response (BERA) and audiological diagnosis. The HHRC showed considerable coverage and a lower evasion rate to perform BERA, with a diagnosis rate of 4.8%. The mean time from the NHS to rehabilitation was longer than recommended. Conclusion NHS coverage must be increased, adjusting the hearing health network to articulate the different levels of care, and reducing the time for identification, diagnosis, and start of rehabilitation.

RESUMO

PURPOSE: The purpose of this study was to verify users' satisfaction with the interface of an audiometric simulator and self-perception of the computer simulation impact on practical acting in audiology, allowing the identification of problems and possibilities for improvement. METHOD: A prospective, observational study was divided into two phases: The first is evaluating the student's satisfaction, using the simulator in the theoretical and practical learning of audiology, and the second one is assessing the self-perception of the simulator's impact on the practical performance of audiology. The sample comprised 35 students from two Speech-Language Pathology and Audiology courses, in Brazil, selected by convenience, who answered the questionnaire after completing the theoretical module, using Google Forms, without any identification. RESULTS: In the first phase of the study, students positively evaluated the use of the simulator as an auxiliary tool for audiology learning, and in the second one, they also positively assessed the impact of training with the simulator in audiological practice. CONCLUSION: The analyzed audiometric simulator proved to be an interactive system with high acceptability, level of satisfaction, and potential impact on practical performance in audiology.

RESUMO

Introdução: A Diabetes Mellitus (DM) é um distúrbio metabólico causado pela ausência ou diminuição da secreção de insulina ou por alterações do funcionamento deste hormônio no organismo, podendo envolver alterações físicas e cognitivas. Objetivo: Analisar os aspectos audiológicos e cognitivos de adultos com Diabetes Mellitus tipo 2. Método: Estudo transversal realizado em pessoas com idade entre 18 e 59 anos, de ambos os gêneros. Os participantes foram divididos em dois grupos: Grupo Estudo (GE) - pessoas com diagnóstico de Diabetes Mellitus e o Grupo Controle (GC) - pessoas sem Diabetes. Todos foram submetidos à avaliação glicêmica, cognitiva e audiológica. Para análise estatística foi utilizado o teste de Mann-Whitney, sendo estipulado o nível de significância de 0,05. Resultados: Participaram do estudo 32 indivíduos sendo 19 (59,4%) no GE e 13 (40,6%) no GC. A média de idade dos participantes foi de 46,8 ± 8,3 anos, com escolaridade média de 6,8 ± 6 anos, sendo 25 (78,1%) do gênero feminino e 7 (21,9%) do masculino. Foi observada diferença estatisticamente significativa entre os grupos para a pontuação referente à atenção e cálculo, recordação e escore total do MEEM, com pior desempenho no GE. Não foi observada diferença estatisticamente significante entre os grupos nos aspectos audiológicos avaliados. Conclusão: Indivíduos com Diabetes Mellitus tipo 2 não apresentaram riscos para alterações audiológicas com os instrumentos utilizados, entretanto apresentaram um alto risco para alterações cognitivas. Os achados demonstram que o acompanhamento fonoaudiológico constante é essencial para identificar as alterações precocemente.

Introduction: Diabetes Mellitus (DM) is a metabolic disorder caused by the absence or reduction of insulin secretion or by changes in the functioning of this hormone in the body, which may involve physical and cognitive changes. Objective: To analyze the audiological and cognitive aspects of type 2 Diabetes Mellitus in adults. Method: Cross-sectional study carried out in people aged between 18 and 59 years, of both genders. Participants were divided into two groups: Study Group (SG) - people diagnosed with Diabetes Mellitus and the Control Group (CG) - people without Diabetes. All underwent glycemic, cognitive and auditory assessment. Mann-Whitney's test was used for statistical analysis, with a significance level of 0.05. Results: 32 individuals participated in the study, 19 (59.4%) in the EG and 13 (40.6%) in the CG. The mean age of the participants was 46.8 ± 8.3 years, with a mean education of 6.8 ± 6 years, with 25 (78.1%) females and 7 (21.9%) males. A statistically significant difference was observed between the groups for the score related to attention and calculation, recall and total Mini-Mental State Examination (MMSE) score, with worse performance in the EG. There was no statistically significant difference between the groups regarding the audiological aspects evaluated. Conclusion: Individuals with type 2 Diabetes Mellitus did not present risks for audiological alterations, however they presented a high risk for cognitive alterations. the findings demonstrate that constant speech therapy monitoring is essential to identify changes early.

RESUMO

AIM: To evaluate the hearing of children with congenital hypothyroidism (CH) and to analyze the knowledge that parents' have on the possible auditory impacts of the disease. METHODS: A total of 263 parents/guardians were interviewed about aspects of CH and hearing. Audiological evaluation was performed on 80 participants, divided into two groups: with CH (n= 50) and without CH (n=30). Clinical and laboratory CH data were obtained from medical records, pure tone auditory thresholds and acoustic reflexes were analyzed. The auditory data was compared between groups. Student's t-test and Chi-square were used for statistical analysis at a significance level of 5% (p ≤0.05). RESULTS: The majority (78%), of the parents were unaware that CH when not treated early is a potential risk to hearing. There was no correlation between socioeconomic class and level of information about CH and hearing (p>0,05; p=0.026). There was a statistically significant difference between the auditory tone thresholds of the groups and between the levels of intensity necessary for the triggering of the acoustic reflex. The group with CH presented the worst results (p≤0.05) and absence of acoustic reflex in a normal tympanometric condition. CONCLUSIONS: Children with CH are more likely to develop damage to the auditory system involving retrocochlear structures when compared to healthy children, and that the disease may have been a risk factor for functional deficits without deteriorating hearing sensitivity. The possible impacts of CH on hearing, when not treated early, should be more publicized among the parents/guardians of this population.

RESUMO

Purpose: The aims of the study were to examine the acoustic reflex screening and threshold in healthy neonates and those at risk of hearing loss and to determine the effect of birth weight and gestational age on acoustic stapedial reflex (ASR). Method: We assessed 18 healthy neonates (Group I) and 16 with at least 1 risk factor for hearing loss (Group II); all of them passed the transient evoked otoacoustic emission test that assessed neonatal hearing. The test battery included an acoustic reflex screening with activators of 0.5, 1, 2, and 4 kHz and broadband noise and an acoustic reflex threshold test with all of them, except for the broadband noise activator. Results: In the evaluated neonates, the main risk factors were the gestational age at birth and a low birth weight; hence, these were further analyzed. The lower the gestational age at birth and birth weight, the less likely that an acoustic reflex would be elicited by pure-tone activators. This effect was significant at the frequencies of 0.5, 1, and 2 kHz for gestational age at birth and at the frequencies of 1 and 2 kHz for birth weight. When the broadband noise stimulus was used, a response was elicited in all neonates in both groups. When the pure-tone stimulus was used, the Group II showed the highest acoustic reflex thresholds and the highest percentage of cases with an absent ASR. The ASR threshold varied from 50 to 100 dB HL in both groups. Group II presented higher mean ASR thresholds than Group I, this difference being significant at frequencies of 1, 2, and 4 kHz. Conclusions: Birth weight and gestational age at birth were related to the elicitation of the acoustic reflex. Neonates with these risk factors for hearing impairment were less likely to exhibit the acoustic reflex and had higher thresholds.

RESUMO

The objective of this study was to evaluate markers of oxidative stress in the brains of rats exposed to lead acetate (Pb(C2 H3 O2 )2 ), either associated or not associated with ferrous sulfate (FeSO4 ). A total of 36 weaning rats (Rattus norvegicus) were divided into 6 groups of six animals and exposed to lead acetate for six weeks. In the control group (control), the animals received deionized water. The Pb260 and Pb260 + Fe received 260 µM lead acetate, and the Pb1050 and Pb1050 + Fe received 1050 µM lead acetate. The Pb260 + Fe and Pb1050 + Fe were supplemented with 20 mg of ferrous sulfate/Kg body weight every 2 days. Group Fe received deionized water and ferrous sulfate. The rat brains were collected to analyze the enzymatic activity of catalase (CAT), superoxide dismutase (SOD), glutathione peroxidase (GPx), and the concentration of reduced glutathione (GSH), lipid peroxidation (TBARS), and total antioxidant substance (TAS) (DPPH• technique). The activity of SOD and GPx in the experimental groups decreased compared to the control, together with the concentration of GSH (p < 0.05). For CAT analysis, SOD tended to increase in concentration in the experimental groups without a concomitant exposure to FeSO4 , whereas GPx showed a slight tendency to increase in activity compared to the control. For TAS-DPPH• , there was a decrease in the experimental groups (p < 0.05). According to the results, SOD, GPx, and GSH were affected by lead acetate and exposure to ferrous sulfate changed this dynamic. However, further studies are needed to verify whether ferrous sulfate acts as a protectant against the toxic effects of lead. © 2016 Wiley Periodicals, Inc. Environ Toxicol 32: 813-822, 2017.

RESUMO

PURPOSE: To analyze the occurrence of acoustic reflex and its threshold on newborns using the 226 and 1,000 Hz probes. METHODS: Thirty-six newborns with "PASS" results in newborn hearing screening and tympanogram with one or two peaks for both probe tones were included. Group I comprised 20 full-term newborns without risk indicator for hearing loss, and Group II comprised 16 newborns with at least one risk indicator. The study about ipsilateral acoustic reflex thresholds was conducted in 500, 1,000, 2,000, and 4,000 Hz. RESULTS: The groups presented the acoustic reflex thresholds between 50 and 100 dB for both probe tones. In the comparison between the probes, there were differences in all frequencies evaluated in Group I, with the lowest threshold mean for the 1,000 Hz probe. In Group II, differences were detected at 2,000 Hz. The mean acoustic reflex thresholds were similar in both groups for the 226 Hz probe. There was a difference for the 1,000 Hz probe in all tested frequencies. The percentage of response was higher in both groups for the 1,000 Hz probe. The kappa test showed extremely poor agreement in the comparison of results between both probes. CONCLUSION: The occurrence of acoustic reflex was higher in newborns and its thresholds were lower with the 1,000 Hz probe both for healthy newborns and for newborns at risk.

RESUMO

Introduction: The effects of lead on children's health have been widely studied. Aim: To analyze the correlation between the long latency auditory evoked potential N2 and cognitive P3 with the level of lead poisoning in Brazilian children. Methods: This retrospective study evaluated 20 children ranging in age from 7 to 14 years at the time of audiological and electrophysiological evaluations. We performed periodic surveys of the lead concentration in the blood and basic audiological evaluations. Furthermore, we studied the auditory evoked potential long latency N2 and cognitive P3 by analyzing the absolute latency of the N2 and P3 potentials and the P3 amplitude recorded at Cz. At the time of audiological and electrophysiological evaluations, the average concentration of lead in the blood was less than 10 ug/dL. Results: In conventional audiologic evaluations, all children had hearing thresholds below 20 dBHL for the frequencies tested and normal tympanometry findings; the auditory evoked potential long latency N2 and cognitive P3 were present in 95% of children. No significant correlations were found between the blood lead concentration and latency (p = 0.821) or amplitude (p = 0.411) of the P3 potential. However, the latency of the N2 potential increased with the concentration of lead in the blood, with a significant correlation (p = 0.030). Conclusion: Among Brazilian children with low lead exposure, a significant correlation was found between blood lead levels and the average latency of the auditory evoked potential long latency N2; however, a significant correlation was not observed for the amplitude and latency of the cognitive potential P3...
