Hearing habits of young adolescent students from public and private schools in the Brazilian Federal District / Hábitos auditivos de jovens adolescentes escolares da rede pública e privada do Distrito Federal

ABSTRACT Purpose: to analyze the hearing habits of a group of students between public and private schools and compare the degree of exposure to sound stimuli via earphones. Methods: 1,085 public and private school students received a questionnaire on hearing habits and exposure to amplified music. Their answers to these questions were analyzed and compared between the groups of students. The chi-square test compared hearing habits between public and private schools, with the statistical significance level set at 5% (p < 0.05). Result: in general, most students (92%) reported hearing habits of exposure to amplified music. Questionnaire answers indicated a high prevalence of both earphone use (92%) and attendance at places with loud music (63.6%). Conclusion: private school students use earphones more often than those from public schools.

Hearing of neonates without risk indicators for hearing loss and use of antimalarial drugs during pregnancy: a historical cohort study in the Northern Region of Brazil / Audição de neonatos sem indicadores de risco para perda auditiva e utilização de antimaláricos na gestação: um estudo de coorte histórica na Região Norte

Abstract Introduction: Studies have demonstrated the ototoxic effects of antimalarial drugs in individuals who receive these drugs, but little is known regarding the toxicity of these drugs in the newborn auditory system when administered to the mother receive the drug during pregnancy. Objective: To verify the incidence of hearing loss in neonates who have no other associated risk indicators, born to mothers treated for malaria during pregnancy. Methods: A retrospective, quantitative cohort study was developed at Hospital de Base Dr. Ary Pinheiro and Clínica Limiar, both located in the municipality of Porto Velho (Rondônia). The sample consisted of 527 newborns divided into two groups: exposed to antimalarials drugs during pregnancy group (n = 32) and non-exposed group (n = 495). Data collection took place from September 2014 to December 2015, through an interview with the mothers and/or guardians of the newborn, through the newborns' and the mothers' records, and the neonatal hearing screening database of the above-mentioned institutions. Results: All the neonates in the exposed group, assessed through the recording of transient otoacoustic emissions associated with the automated brainstem auditory evoked potential test, underwent neonatal hearing screening in the first examination. Among the newborns in the non-exposed group, 30 showed failure and were retested. Of these, one continued to fail and was referred for diagnosis, in whom the results showed to be within the normal range. Among the neonates of the exposed group, infection with Plasmodium vivax was the most frequent, and was similarly distributed among the gestational trimesters, and chloroquine was the most commonly used antimalarial drug treatment more often given during the third trimester; these findings did not show any influence on the audiological findings of the studied neonates. Conclusion: The present study did not identify any cases of hearing loss in neonates born to mothers who used antimalarial drugs during gestation.

Resumo Introdução: Estudos comprovam os efeitos ototóxicos dos antimaláricos em pessoas que fazem uso destes medicamentos, porém pouco se sabe sobre a toxicidade destes fármacos no sistema auditivo de neonatos quando ingeridos pelas mães no período gestacional. Objetivo: Verificar a incidência de perda auditiva em neonatos de mães tratadas para malária durante a gestação sem outros indicadores de risco associados. Método: Estudo quantitativo, de coorte retrospectivo, desenvolvido no Hospital de Base Dr. Ary Pinheiro e na Clínica Limiar, ambos em Porto Velho (Rondônia). Compuseram a amostra 527 recém-nascidos divididos em dois grupos: grupo exposto (n = 32) e grupo não exposto (n = 495). A coleta de dados ocorreu de setembro de 2014 a dezembro de 2015, através de entrevista com as genitoras e/ou responsáveis pelo recém-nascido, investigação nos prontuários dos neonatos e das genitoras e no banco de dados da triagem auditiva neonatal das instituições supracitadas. Resultados: Todos os neonatos do grupo exposto, avaliados através do registro das emissões otoacústicas transientes associado a realização do potencial evocado auditivo de tronco encefálico automático passaram na triagem auditiva neonatal no primeiro exame. Já, entre os recém-nascidos do grupo não exposto, 30 apresentaram falha e foram retestados. Destes, um continuou falhando e foi encaminhado para diagnóstico, no qual foram evidenciados resultados dentro da normalidade. Nos neonatos do grupo exposto, a infecção pelo Plasmodium vivax foi a mais frequente, mostrando distribuição semelhante entre os trimestres gestacionais, sendo a cloroquina o antimalárico mais utilizado e o tratamento medicamentoso realizado mais frequentemente no terceiro trimestre, porém tais achados não mostraram influência sobre os achados audiológicos dos neonatos estudados. Conclusão: O presente estudo não identificou casos de perda auditiva nos neonatos de mães que utilizaram antimaláricos na gestação.

High-frequency conductive hearing loss as a diagnostic test for incomplete ossicular discontinuity in non-cholesteatomatous chronic suppurative otitis media.

Chronic suppurative otitis media, with or without cholesteatoma, may lead to erosion of the ossicles and discontinuity of the ossicular chain. In incomplete ossicular discontinuity (IOD), partial erosion of the ossicles occurs, but some sound transmission is noted throughout the ossicular chain. High-frequency conductive hearing loss (HfCHL) has been considered a hallmark of incomplete ossicular discontinuity. This study aims to evaluate the use of HfCHL as a preoperative predictor of IOD in patients with non-cholesteatomatous chronic suppurative otitis media. The HfCHL test was defined as the preoperative air-bone gap (ABG) at 4 kHz minus the average of the ABG at 0.25 and 0.5 kHz. The test was applied in 328 patients before surgery and compared to intraoperative findings as the gold standard. At surgery, 201 (61.3%) patients had an intact ossicular chain, 44 (13.4%) had a complete ossicular discontinuity, and 83 (25.3%) exhibited an IOD. The best cutoff level was calculated as 10 dB. The HfCHL test to diagnose IOD had a sensitivity of 83% and a specificity of 92% with a post-test probability of 78% and a likelihood ratio of 10.2. We concluded that the HfCHL test is highly effective in predicting IOD in patients with non-cholesteatomatous chronic suppurative otitis media and that it should be used routinely as a screening test prior to surgery.

Analysis of Hearing and Tinnitus in Workers Exposed to Occupational Noise.

INTRODUCTION: Noise is one of the harmful agents to health that is present in the various branches of economic activity. Hearing loss and tinnitus are among the most frequently reported complaints by workers exposed to occupational noise. OBJECTIVE: To analyze the hearing and tinnitus in normal-hearing workers exposed to occupational noise. METHODS: This is a cross-sectional analytical trial in metallurgical industries, in which we evaluated normal-hearing workers through anamnesis, audiometry and otoacoustic emissions. RESULTS: It was observed high prevalence of failure of otoacoustic emissions (40%) and tinnitus (66.6%). Both in the amplitude and in the signal-to-noise ratio, the higher is the frequency of the sound, the worse the results. Despite having audiometry within normal limits, the results indicate that workers are suffering the effects of exposure and reveals association between failure of otoacoustic emissions and tinnitus in this population (X2 = 6,732). CONCLUSION: It is concluded that failures in DPOAE and tinnitus are predictors of hearing damage in normal-hearing workers.

Intratympanic corticosteroid for sudden hearing loss: does it really work? / Corticosteroide intratimpânico para perda súbita da audição: isso realmente funciona?

ABSTRACT INTRODUCTION: Sudden deafness is characterized by an abrupt hearing loss of at least 30 dB in three sequential frequencies in the standard pure tone audiogram over three days or less. Treatment is based on its etiology, and oral corticosteroids are widely used. Intratympanic corticosteroids are included as primary or secondary treatment when there is no improvement with the use of oral corticosteroids. OBJECTIVE: To determine the effectiveness of therapy with intratympanic steroids in sudden deafness. METHODS: A systematic review was performed of publications on the topic in the databases of PubMed/MEDLINE, with the keywords: sudden deafness, sudden hearing loss, and corticosteroids. RESULTS: Thirty scientific studies were analyzed. As to the objectives of the study analyzed, 76.7% sought to evaluate the use of intratympanic therapy salvage after failure to conventional treatment, and intratympanic therapy was used as the primary treatment 23.3% of the studies. CONCLUSION: Intratympanic corticosteroid therapy is prescribed primarily when there is failure of conventional therapy and when it is limited to use systemic corticosteroids, such as the diabetic patient.

Resumo Introdução: A surdez súbita é caracterizada por uma perda abrupta da audição de pelo menos 30 dB em três frequências sequenciadas no audiograma tonal de rotina ao longo de três dias, oumenos. O tratamento é fundamentado em sua etiologia e corticosteroides orais são amplamenteutilizados. A terapia com corticosteroide intratimpânico foi incluída como tratamento primárioou secundário nos casos em que não houve melhora com o uso de corticosteroides orais. Objetivo: Determinar a eficácia da terapia intratimpânica com esteroides em casos de surdez súbita. Método: Foi realizada uma revisão sistemática das publicações sobre o tópico no banco dedados Pubmed/Medline, com as palavras-chave: surdez súbita, perda súbita da audição e corticosteroides. Resultados: Foram analisados 30 estudos científicos. Com relação aos objetivos dos estudos analisados, 76,7% procuravam avaliar o uso da terapia intratimpânica em seguida ao insucesso com o tratamento convencional; a terapia intratimpânica foi empregada como tratamento primário em 23,3% dos estudos. Conclusão: A terapia com corticosteroide intratimpânico é prescrita primariamente nos casos de insucesso com a terapia convencional e quando há limitação para o uso de corticosteroides sistêmicos, como ocorre com o paciente diabético.

Risk of hearing alterations in newborns of mothers treated for malaria.

INTRODUCTION: The antimalarial drugs can cause irreversible sensorineural hearing loss, and chloroquine phosphate use can be ototoxic to the fetus. OBJECTIVE: To compare the results of hearing screening in newborns of mothers treated for malaria in pregnancy with the results of newborns of mothers untreated and check for increased risk of hearing alterations in the group exposed to treatment. METHOD: Retrospective cohort study which involved 284 infants, 30 in the exposed group to malaria treatment and 254 in the unexposed group, matched for gestational age, birth weight and risk indicators for hearing. They underwent hearing screening by means of transient evoked otoacoustic emissions and/or auditory brainstem response automatic. The variables were collected in an interview with the parents in the health record and the screening database. RESULTS: The prevalence of fail in exposed group (6.7%) was significant when compared with the unexposed group (1.2%). The risk of failing in the hearing screening in the exposed group was 5.64 (CI 1.17 to 27.3). CONCLUSION: Newborns of mothers treated for malaria in pregnancy had a prevalence of fail in hearing screening at 6.7% and 5.64 higher chances to fail than newborns of untreated mothers.

Association between suppression of otoacoustic emissions and annoyance levels in tinnitus patients with normal hearing.

OBJECTIVE: To correlate the annoyance of tinnitus assessed by the Tinnitus Handicap Inventory and on a visual analogue scale with the evoked otoacoustic emission test result in tinnitus patients with normal hearing. STUDY DESIGN: Case-control study. SETTING: Public tertiary hospital. SUBJECTS AND METHODS: The sample was initially based on a population of 80 subjects with tinnitus; 20 of them had normal hearing and normal evoked otoacoustic emission test results and comprised the study group. For the purpose of comparison, a control group was formed, which consisted of 17 subjects with no hearing complaints and normal hearing. The participants were submitted to hearing tests, immittance testing and tests for the evaluation of acoustic reflexes, distortion product otoacoustic emissions, transient evoked otoacoustic emissions (TEOAEs), and suppression of TEOAEs. The tests were performed in a sound-treated booth using a linear contralateral noise of 60 dB. The presence of suppression effects was defined when the response amplitude was 0.5 dB or higher. RESULTS: Abnormal evoked otoacoustic emission suppression test results were observed in 52.9% of tinnitus patients and in 32.4% of control subjects (p = 0.086). Suppression effects of TEOAEs were absent in 38.5% of subjects with minimal or mild discomfort and in 61.9% of subjects with moderate or severe discomfort (p = 0.183). CONCLUSION: It was not possible to associate the annoyance caused by tinnitus with the TEOAE suppression test results, although suppression effects were found to decrease with increasing annoyance.

Electrocochleography for Ménière's disease: is it reliable?

INTRODUCTION: Endolymphatic hydrops, the histopathological substrate of Ménière's disease, is an almost universal finding in postmortem studies of patients with this disease. The cause of hydrops is still unknown, as is the mechanism by which it causes progressive dysfunction of the sensory organs of inner ear. The fluctuating course of the disease complicates the interpretation of certain tests, such as electrocochleography; thus, for some authors its diagnostic value is questionable. OBJECTIVE: The aim of this study was to analyze the clinical applicability of electrocochleography in the diagnosis of hydrops. It is a valuable tool, but still generates conflicting opinions among otolaryngologists. METHODS: Systematic review of the literature on electrocochleography in patients diagnosed with endolymphatic hydrops. RESULTS: A total of 34 articles regarding the use of electrocochleography in patients with hydrops, from the year 2000 onwards, were selected. Of these, 15 were excluded from the review as they were not observational studies. Only one cross-sectional study addressing the clinical use of electrocochleography by otolaryngologists was included. CONCLUSION: Electrocochleography is a valuable tool in the diagnosis of hydrops, as it is a non-invasive, easy to handle procedure, which offers new techniques to increase the sensitivity of the test, and thereby assists otolaryngologists in the management of Ménière's disease.

Introdução: A hidropisia endolinfática é o substrato histopatológico e achado quase universal nos estudos post-mortem de pacientes com doença de Ménière. A causa da hidropisia ainda é desconhecida, assim como o mecanismo pelo qual causa disfuncção progressiva dos órgãos sensitivos da orelha interna. O curso flutuante da doença dificulta a interpretação de exames como a eletrococleografia, que apresenta, para alguns autores, valor diagnóstico controverso. Objetivos: O objetivo deste estudo é analisar a aplicabilidade clínica da eletrococleografia no diagnóstico da hidropisia endolinfática, sendo uma ferramenta de uso comum e que ainda gera opiniões conflitantes entre os otorrinolaringologistas. Método: Revisão sistemática da literatura sobre eletrococleografia em pacientes com diagnóstico de hidropisia endolinfática. Resultados: Foram selecionados 34 artigos sobre o uso da eletrococleografia em pacientes portadores de hidropisia endolinfática a partir do ano 2000; 15 artigos foram excluídos da revisão por não se tratarem de estudos observacionais, com inclusão de somente um estudo transversal que trata sobre o uso clínico da eletrococleografia entre os otorrinolaringologistas. Conclusão: A eletrococleografia é uma importante ferramenta no diagnóstico da hidropisia endolinfática, por ser não invasiva, de fácil mensuração, e por oferecer novas técnicas capazes de aumentar a sensibilidade do exame e auxiliar o otorrinolaringologista no tratamento da Doenca de Ménière. .

Comparative analysis of vocabulary in children with cochlear implants.

INTRODUCTION: The use of tests assessing the speech of patients who underwent cochlear implant (CI) surgery is warranted to increase knowledge on the development of these patients' language skills. The ABFW Child Language Test evaluates vocabulary, phonology, fluency, and pragmatics and can be administered to these children. OBJECTIVE: To evaluate the vocabulary of children using CI. METHOD: This study included 16 children who underwent CI surgery between 1-4 years and 11 months old. Patients were divided into five groups according to age upon CI activation. RESULTS: In comparison with the age of brain's auditory development vs. chronological age of hearing children, all children using CI performed better. The comparison between children using unilateral CI and bilateral CI showed that those using bilateral CI had better results. When we compared children's performance considering the chronological age of deaf and hearing children, hearing children performed better. However, there were similar results when patients effectively used their CI and attended auditory rehabilitation sessions. CONCLUSION: In our study, the vocabulary of children using CI is similar to the vocabulary of hearing children.

Eagle's Syndrome

Eagle's syndrome is characterized by cervicopharyngeal signs and symptoms associated with elongation of the styloid apophysis. This elongation may occur through ossification of the stylohyoid ligament, or through growth of the apophysis due to osteogenesis triggered by a factor such as trauma. Elongation of the styloid apophysis may give rise to intense facial pain, headache, dysphagia, otalgia, buzzing sensations, and trismus. Precise diagnosis of the syndrome is difficult, and it is generally confounded by other manifestations of cervicopharyngeal pain. OBJECTIVE: To describe a case of Eagle's syndrome. CASE REPORT: A 53-year-old man reported lateral pain in his neck that had been present for 30 years. Computed tomography (CT) of the neck showed elongation and ossification of the styloid processes of the temporal bone, which was compatible with Eagle's syndrome. Surgery was performed for bilateral resection of the stylohyoid ligament by using a transoral and endoscopic access route. The patient continued to present pain laterally in the neck, predominantly on his left side. CT was performed again, which showed elongation of the styloid processes. The patient then underwent lateral cervicotomy with resection of the stylohyoid process, which partially resolved his painful condition. FINAL COMMENTS: Patients with Eagle's syndrome generally have a history of chronic pain. Appropriate knowledge of this disease is necessary for adequate treatment to be provided. The importance of diagnosing this uncommon and often unsuspected disease should be emphasized, given that correct clinical-surgical treatment is frequently delayed. The diagnosis of Eagle's syndrome is clinical and radiographic, and the definitive treatment in cases of difficult-to-control pain is surgical...

Stapedotomy in a residency training program.

INTRODUCTION: The major objective of a stapedotomy is the restoration of hearing. In training centers, the hearing results obtained by resident physicians are lower than those achieved by more experienced surgeons. An analysis of the surgical results obtained by resident physicians is essential to identification of the deficiencies in the learning process. OBJECTIVE: To analyze the postoperative hearing results obtained by otosclerosis patients who underwent stapedotomy performed by surgeons in a residency program. METHODS: The pre- and postoperative audiometric results were evaluated in a retrospective study of 98 otosclerosis patients who underwent stapedotomy from January 2000 to December 2010. RESULTS: The distribution of patients according to the postoperative results was as follows: 68.4% of the patients achieved a postoperative gap of less than or equal to 10 dB, and 91.8% of the patients achieved a postoperative gap of less than or equal to 20 dB. Three (3.1%) patients had profound sensorineural hearing loss after the procedure. CONCLUSIONS: An improvement in surgical outcomes of doctors in training is essential for the continuation of training for stapes surgery during medical residency.
