Translation and cultural adaptation of "Glasgow Children's Benefit Inventory" into Brazilian Portuguese

Abstract Objective Translate and cross-culturally adapt into Brazilian Portuguese the Glasgow Children's Benefit Inventory instrument used for the quality-of-life assessment after pediatric ENT interventions. Method This is a methodological study of translation and cross-cultural adaptation of the GCBI instrument following seven stages: 1) Translation of two versions by two independent translators, 2) Elaboration of a consensual synthetized version, 3) Assessment of the synthetized version by experts, 4) Assessment by the target audience, 5) Back-translation, 6) Pilot study and 7) Use of the instrument. The final version of the instrument was answered by a sample of 28 people responsible for children aged from 2 to 7 years, submitted to tonsillectomy between January 2019 and December 2021, in a public hospital in Porto Alegre. The collection considered patients with a minimum of 6-months and a maximum of 3-years of postoperative follow-up. Result The instrument final version was compared to the original version showing semantic equivalence, absence of consistent translation difficulties and appropriate cross-cultural adaptation, and well understood by the target audience. The application of the questionnaire in the sample showed a Cronbach alpha coefficient of 0.944 corresponding to a high degree of reliability of the instrument. Conclusion The translation and cross-cultural adaptation showed semantic appropriateness and its use when assessing ENT postoperative results in a pediatric population showed high reliability of the instrument. Level of evidence 4.

Experimental cholesteatoma: a comparison between spontaneous and induced models

Abstract Objective: To compare the incidence and the histopathological aspect of spontaneous and two induced Mongolian gerbils' models of cholesteatoma: External Auditory Canal (EAC) obliteration model and the Auditory Tube (AT) cauterization model. Methods: Fifty-four ears of 27 animals were divided into EAC obliteration, AT cauterization, and control groups and histologically assessed for cholesteatoma incidence and classification at intervals of 2, 4, 8, and 16 weeks. Results: Cholesteatoma was diagnosed in 30 of the 53 ears evaluated with a significantly higher incidence in groups that received some type of intervention (p < 0.0001). It was not possible to histologically distinguish cholesteatomas of the same stage between the study groups. Conclusion: Although we observed a significant increase in cholesteatoma incidence with the two methods used when compared to the control group, all developed cholesteatomas were apparently identical from a histological point of view.

Critical analysis of moderate and severe retractions in the pars tensa and pars flaccida of the tympanic membrane,

Abstract Objectives: Analyze the prevalence of retractions in different areas of the Tympanic Membrane (TM), the correlations between the involvement of the Pars Tensa (PT) and Pars Flaccida (PF), and the air-bone gaps. Methods: A cross-sectional study. Patients with moderate and/or severe TM retraction of 2200 consecutive patients with chronic otitis media between August 2000 and January 2019 were included. Ears with previous surgery were excluded. Ears were classified as isolated PF and PT retractions and association of both. The degrees of severity and presence of effusion were evaluated. The data were analyzed using the SPSS Statistics software program. Results: 661 ears were included. The prevalence of isolated atical retractions was 24.9%, of isolated posterior quadrants was 10.6%, and of association of quadrants was 64%. There was no correlation between the retractions in the different areas of the TM (posterior and attic quadrants: r = 0.13; p = 0.041; anterior and posterior quadrants: r = 0.23; p = 0.013, anterior and attic quadrants: r = 0.06; p = 0.043). Effusion was present in 30.7% of the ears. ABG median was lower in ears with PF retraction (6.25 dB HL) than PT retraction, isolated (15 dB HL) or not (13.75 dB HL; p < 0.05); 72% of the ears had an ABG ≤ 20dB HL. For severity of the retraction of PF, the ABG was similar across groups. For the PT, there was a global difference in the medians of ABG in terms of the degree of severity, with a moderate correlation. Conclusion: The prevalence of moderate and severe retractions was 24.5%; 64% of the ears had an association of affected regions. There was no correlation between the retraction in the different areas of the TM. We found a significant correlation between the severity of retraction and the worsening of ABG threshold, only for PT. Evidence level: 4.

Assessment of the Sensitivity of the Vocal Tract in Parkinson Disease by Nasal Video Endoscopy

Abstract Introduction Sensory deficits of the upper airways are common in people with Parkinson disease. Compounded by considerable deterioration of the swallowing function, these deficits may contribute to the elevated rates of morbidity and mortality among this population. Objective To examine the sensitivity of the vocal tracts of people with Parkinson disease using nasal videoendoscopy and to compare the results with paired controls. Methods The present was a prospective, observational, case-control study. Sensitivity assessments were conducted in a sample of 24 people divided into 2 groups: one group of 12 patients with Parkinson's disease, and a control group with 12 healthy subjects. The study group also underwent a fiberoptic endoscopic evaluation of swallowing and answered the Swallowing Disturbance Questionnaire (SQD) to detect dysphagia. Results There was a significant difference (p < 0.05) in the region of the arytenoid cartilages, showing that sensitivity was better preserved among the control group, and that sensitivity deficits were present in the study group. The qualitative results showed sensorial impairment in the study group than in the control group regarding the base of the tongue, the vestibular folds, and the vocal folds. The study group showed self-awareness regarding the deficits in the swallowing function, but there was no statistically significant association between swallowing function deficits and deterioration of sensorial function among them. Conclusions Sensorial deficits were present in the study group when compared to the healthy subjects, mainly in the qualitative evaluation.

Mongolian Gerbils as a Model for the Study of Cholesteatoma: Otoendoscopic as a Diagnostic Tool

Abstract Introduction Cholesteatoma is a disease with significant clinical impact but is incompletely understood. The challenge of performing studies with long-term follow-up in humans is a factor that has restricted the advance of knowledge in this field. Thus, the use of animal models is highly pertinent, and the Mongolian gerbil model has emerged as one of the most useful. Objective The present study aims to evaluate, through serial otoendoscopies, the development and characteristics of pars flaccida retraction pocket and cholesteatoma in Mongolian gerbils after obliteration of the eustachian tube and compare it with the control group. Methods Forty Mongolian gerbils were divided into two groups of 20 animals each. In the intervention group, the animals were followed with serial otoendoscopies after eustachian tube obliteration. In the control group, the animals were only followed through serial otoendoscopies. Results At the end of the 16-week follow-up, cholesteatoma was present in 13 of 38 (34.2%) ears in the intervention group, and in 7 of 34 (20.6%) in the control group (p = 0.197). When we considered cholesteatoma and its potential precursor, pars flaccida retraction pocket, in a combined way, we verified it in 23 of 38 (60.8%) in the intervention group and in 11 of 34 (32.3%) in the control group (p = 0.016). Conclusions Over the 16 weeks of follow-up, serial otoendoscopies enabled us to evaluate the formation and development of pars flaccida retraction pockets and cholesteatomas in Mongolian gerbils and proved to be an excellent diagnostic tool.

Quality of life in tongue cancer treated patients before and after speech therapy: a randomized clinical trial / Qualidade de vida em pacientes tratados por câncer de língua pré e pós fonoterapia: ensaio clínico randomizado

Abstract Introduction: Tongue cancer is one of the most common subtypes of head and neck cancer. The aggressive effects of treatment cause aesthetic, psychosocial and functional deficits, especially dysphagia, which affects patient quality of life. Rehabilitation, which is essential for functional maximum recovery, helps patients deal with new and altered structures and has a positive impact on quality of life. Objective: To verify the impact of speech therapy on swallowing quality of life in tongue cancer patients after treatment. Methods: This parallel randomized clinical trial was conducted at a public hospital in Porto Alegre, RS, Brazil. Before and after the intervention, a quality of life questionnaire (the Deglutition Handicap Index) was employed, dysphagia severity was assessed with fiberoptic endoscopic evaluation of swallowing, and the Functional Oral Intake Scale carried out. The experimental group underwent four-week sessions of speech therapy over one month, while the control group received the institution's usual follow-up. Results: Thirty individuals treated for tongue cancer were divided into a study and a control group. Deglutition Handicap Index scores decreased significantly (approximately 40 points) (p < 0.001) after the intervention in the study group. There was a significant correlation between improved quality of life, reduced dysphagia severity and increased in Functional Oral Intake Scale scores (p <0.001). Conclusion: After speech therapy, quality of life scores related to deglutition and dysphagia severity improved in patients treated for tongue cancer.

Resumo Introdução: O câncer de língua é um dos subtipos mais comuns do câncer de cabeça e pescoço. Os efeitos agressivos do tratamento causam impactos estéticos, psicossociais e funcionais, principalmente a disfagia, os quais afetam a qualidade devida do paciente. A reabilitação, essencial para a máxima recuperação funcional, auxilia o paciente a lidar com as novas estruturas e tem impacto positivo na qualidade de vida. Objetivo: Verificar o impacto da fonoterapia na Qualidade de Vida relacionada à deglutição de pacientes tratados por câncer de língua. Método: Ensaio clínico randomizado paralelo, realizado em um hospital público de Porto Alegre, RS, Brasil. Antes e após a intervenção, os participantes foram avaliados por meio de um questionário de Qualidade de Vida (o Índice de Desvantagem da Deglutição), classificados quanto a gravidade da disfagia (por meio do exame de Videoendoscopia da Deglutição) e quanto ao nível da escala funcional de ingestão por via oral. O grupo experimental foi submetido a quatro sessões semanais de fonoterapia no período de um mês, enquanto o grupo controle recebeu o acompanhamento habitual da instituição. Resultados: Trinta indivíduos tratados para câncer de língua foram divididos em um grupo estudo e um grupo controle. Houve uma diminuição significativa, de aproximadamente 40 pontos (p <0,001), nos escores de Qualidade de Vida após a intervenção no grupo experimental. Verificou-se correlação significativa entre a melhora da Qualidade de Vida, a redução da gravidade da disfagia e o aumento dos níveis da escala funcional de ingestão por via oral (p <0,001). Conclusão: Após a fonoterapia, pacientes tratados por câncer de língua apresentaram melhora nos escores de Qualidade de Vida relacionada à deglutição e na gravidade da disfagia.

Endoscopic-Assisted Canal Wall-up Tympanomastoidectomy for Reduction of Residual Cholesteatoma

Abstract Introduction The treatment of cholesteatoma is generally surgical, and the major obstacle is the high prevalence of recidivism. The endoscopic ear surgery technique is proposed to minimize this problem. Objectives To utilize endoscopes to visualize and manipulate cholesteatoma residues after microscopic removal Methods Cross-sectional study. Thirty-two patients with cholesteatoma underwent microscopic wall-up mastoidectomy combined with the endoscopic approach. The subjects were assessed for the presence and location of covert disease. Results Of the 32 cases, 17 (53.12%) had residual cholesteatoma in the endoscopic phase. Minimal disease was found, usually fragments of the cholesteatoma matrix. Pars tensa cholesteatomas had more covert disease than pars flaccida cholesteatomas (62.50% vs 43.75%). Posterior recesses (47.05%) and tegmen tympani (41.17%) were the locations with more covert disease (p< 0.05). Conclusion Cholesteatomas of the pars tensa presented more residual disease and were significantly more common in the posterior recesses and tegmen tympani.

Does universal newborn hearing screening impact the timing of deafness treatment?

Abstract Objective: To evaluate the impact of the Universal Neonatal Hearing Screening (UNHS) on the age at diagnosis, beginning of treatment, and first cochlear implant surgery. Methods: A retrospective cohort study with children up to 12 years old with bilateral hearing loss were divided into two groups: patients who underwent UNHS and the ones who didn't. The groups were compared according to their age at the beginning of the evaluation at a specialized center, at the beginning of the intervention, and, for the ones who had indication, at the cochlear implant surgery. The group who underwent UNHS was divided between the ones who passed the screening test and the ones who didn't. They were compared according to their ages at the same moments as the first two groups. Results: 135 patients were included. The median age at the first appointment in a specialized center was 1.42 (0.50 and 2.50) years, at the beginning of treatment 2.00 (1.00 and 3.52) years, and the cochlear implant surgery 2.83 (1.83 and 4.66) years. Children who underwent UNHS were younger than those who didn't, at the three evaluated moments (p < 0.001). In a subanalysis, children who passed the UNHS but were later diagnosed with hearing loss reached the first appointment with a specialist and started treatment older than those who failed the tests. Conclusion: Performing UNHS interfered with the timing of deafness diagnosis and treatment. However, children who passed the screening but were later diagnosed with hearing loss were the category with the most important delay.

O uso do Sistema de Frequência Modulada por crianças e adolescentes atendidos em serviço de saúde auditiva / The use of system of Frequency Modulation by children and adolescents from a hearing health care service

RESUMO Objetivo Analisar o uso e os motivos para o não uso do Sistema de Frequência Modulada (FM) por crianças e adolescentes com perda auditiva e usuários de aparelhos de amplificação sonora individual (AASI) e/ou com implante coclear (IC). Métodos Foi aplicado um questionário em forma de entrevista, por meio de contato telefônico. As questões foram retiradas do questionário FM Listening Evaluation for Children, traduzido e adaptado para a língua portuguesa por Jacob et al. (2010) e denominado Avaliação do Sistema FM, bem como outras três perguntas elaboradas pelos pesquisadores. Resultados Foram entrevistados 87 pais/responsáveis, verificando-se que o sistema FM era utilizadopor menos da metade da amostra. Quanto à mediana de uso de horas diárias do sistema, observou-se diferença nos pacientes com FM no IC, que usavam o dispositivo por maior número de horas diárias, do que os usuários de AASI. Igualmente apresentou diferença estatística o principal motivo para onão uso, relacionado ao fato de os pacientes terem recebido novos AASI e/ou IC incompatíveis com a tecnologia obtida anteriormente. Ainda, os entrevistados gostariam que lhes fossem fornecidas melhores orientações. Conclusão a maior parte dos pacientes não utiliza o sistema FM, sendo o principal motivo o uso de novos AASI e/ou IC. Os pacientes com IC usam o FM de forma mais efetiva (diariamente).

ABSTRACT Purpose To analyze de use and reasons for not using of FM systems by children and adolescents with hearing loss and users of hearing aids (HA) and or cochlear implant (CI). Methods A questionnaire applied in the form of an a interview through telephone contact was used. The questions were removed from the questionnaire "FM Listening Evaluation for children", translated and adapted for Portuguese language by Jacob et al. (2010) and named "Avaliação do Sistema FM", and three other questions prepared by the researchers. Results 87 parents/guardians were interviewed, and it was verified that less than half of the sample used the FM system. As for the median use of the FM systems daily hours, there was a statistical difference in patients with FM in CI, Who used the device for a greater number of daily hours than hearing AID users. The main reason for non-use also presented statistical difference to the fact that patients have received new hearing aids and/or CI incompatible with previously obtained. Also, respondents would like the guidance provided improved. Conclusion Most patients did not use the FM system, the main reason being the usage of new hearing aids and/or CI. Patients with CI use FM more effectively (daily).

Central auditory processing in teenagers with non-cholesteatomatous chronic otitis media / Processamento auditivo central em adolescentes com otite média crônica não colesteatomatosa

Abstract Introduction: Evidences of possible effects of early age otitis media with effusion in the central auditory processing, emphasize the need to consider such effects also in subjects with chronic otitis media. Aim: To investigate and analyze the impact of non-cholesteatomatous chronic otitis media on central auditory processing in teenagers. Methods: This is a study in which 68 teenagers were recruited, 34 with a diagnosis of non-cholesteatomatous chronic otitis media (study group) and 34 without otological disease history (control group). The evaluation of the subjects consisted of: anamnesis, pure-tone threshold audiometry, speech audiometry and a behavioral test battery for assessment of central auditory processing. Results: A statistically significant difference was found between the means observed in the study and control groups in all tests performed. An association was found between the control group and subgroups of the study group with unilateral alterations in all tests. An association was shown between the results for the control group and study group for family income, with a greater impact on subjects with a lower income. Conclusions: Non-cholesteatomatous chronic otitis media affects the central auditory processing in teenagers suffering from the disorder, and monaural low-redundancy hearing is the most affected auditory mechanism. Unilateral conductive changes cause more damage than bilateral ones, and lower family income seems to lead to more changes to the central auditory processing of subjects with non-cholesteatomatous chronic otitis media.

Resumo Introdução: As evidências de prováveis efeitos de otite média com efusão precoce no proces-samento auditivo central, ressaltam a necessidade de se considerar tais efeitos também em sujeitos com otite média crônica. Objetivo: Investigar e analisar o impacto da otite média crônica não colesteatomatosa no processamento auditivo central em adolescentes. Método: Estudo para o qual foram recrutados 68 adolescentes, 34 com diagnóstico de otite média crônica não colesteatomatosa (grupo de estudo) e 34 sem história otológica (grupo controle). A avaliação dos indivíduos consistiu de: anamnese, audiometria do limiar auditivo para tons puros, audiometria vocal e bateria de testes comportamentais para avaliação do processamento auditivo central. Resultados: Foi encontrada uma diferença estatisticamente significante entre as médias observadas nos grupos de estudo e controle em todos os testes. Foi encontrada uma associação entre o grupo controle e os subgrupos do grupo de estudo com alterações unilaterais em todos os testes. Houve associação entre os resultados dos grupos controle e de estudo para a renda familiar, com maior impacto nos indivíduos com menor renda. Conclusões: A otite média crônica não colesteatomatosa afeta o processamento auditivo central em adolescentes, a audição monoaural de baixa redundância é o mecanismo auditivo mais afetado. Alterações condutivas unilaterais causam mais danos do que as bilaterais e a menor renda familiar parece conduzir a mais alterações no processamento auditivo central de indivíduos com otite média crônica não colesteatomatosa.

Cholesteatoma labyrinthine fistula: prevalence and impact / Fístula labiríntica por colesteatoma: prevalência e impacto

Abstract Introduction: Labyrinthine fistula is one of the most common complications associated with cholesteatoma. It represents an erosive loss of the endochondral bone overlying the labyrinth. Reasons for cholesteatoma-induced labyrinthine fistula are still poorly understood. Objective: Evaluate patients with cholesteatoma, in order to identify possible risk factors or clinical findings associated with labyrinthine fistula. Secondary objectives were to determine the prevalence of labyrinthine fistula in the study cohort, to analyze the role of computed tomography and to describe the hearing results after surgery. Methods: This retrospective cohort study included patients with an acquired middle ear cholesteatoma in at least one ear with no prior surgery, who underwent audiometry and tomographic examination of the ears or surgery at our institution. Hearing results after surgery were analyzed according to the labyrinthine fistula classification and the employed technique. Results: We analyzed a total of 333 patients, of which 9 (2.7%) had labyrinthine fistula in the lateral semicircular canal. In 8 patients, the fistula was first identified on image studies and confirmed at surgery. In patients with posterior epitympanic and two-route cholesteatomas, the prevalence was 5.0%; and in cases with remaining cholesteatoma growth patterns, the prevalence was 0.6% (p = 0.16). In addition, the prevalence ratio for labyrinthine fistula between patients with and without vertigo was 2.1. Of patients without sensorineural hearing loss before surgery, 80.0% remained with the same bone conduction thresholds, whereas 20.0% progressed to profound hearing loss. Of patients with sensorineural hearing loss before surgery, 33.33% remained with the same hearing impairment, whereas 33.33% showed improvement of the bone conduction thresholds' Pure Tone Average. Conclusion: Labyrinthine fistula must be ruled out prior to ear surgery, particularly in cases of posterior epitympanic or two-route cholesteatoma. Computed tomography is a good diagnostic modality for lateral semicircular canal fistula. Sensorineural hearing loss can occur post-surgically, even in previously unaffected patients despite the technique employed.

Resumo Introdução: A fístula labiríntica é uma das complicações mais comuns associadas ao colesteatoma. Representa uma perda erosiva do osso endocondral que recobre o labirinto. As razões para a ocorrência da fístula labiríntica induzida pelo colesteatoma ainda são mal compreendidas. Objetivo: Avaliar pacientes com colesteatoma, a fim de identificar possíveis fatores de risco ou achados clínicos associados à fístula labiríntica. Os objetivos secundários foram determinar a prevalência de fístula labiríntica no estudo de coorte, analisar o papel da tomografia computadorizada e descrever os resultados auditivos após a cirurgia. Método: Este foi um estudo de coorte retrospectivo. Foram incluídos pacientes com colesteatoma adquirido de orelha média em pelo menos um lado sem cirurgia prévia que haviam sido submetidos à audiometria e tomografia computadorizada de orelha ou cirurgia em nossa instituição. Os resultados auditivos após a cirurgia foram analisados de acordo com a classificação de fístula labiríntica e da técnica empregada. Resultados: Analisamos um total de 333 pacientes, dos quais 9 (2,7%) apresentavam fístula labiríntica no canal semicircular lateral. Em 8 pacientes, a fístula foi identificada na tomografia computadorizada e confirmada durante a cirurgia. Em pacientes com colesteatomas epitimpânicos posteriores e de via dupla, a prevalência foi de 5,0%; e nos casos com padrão de crescimento de colesteatoma remanescente, a prevalência foi de 0,6% (p = 0,16). Além disso, a taxa de prevalência de fístula labiríntica entre pacientes com e sem vertigem foi de 2,1. Dos pacientes sem perda auditiva neurossensorial antes da cirurgia, 80,0% permaneceram com os mesmos limiares de condução óssea, enquanto 20,0% progrediram para perda auditiva profunda. Dos pacientes com perda auditiva neurossensorial antes da cirurgia, 33,33% permaneceram com a mesma deficiência auditiva, enquanto 33,33% apresentaram melhora da média de dos limiares de condução óssea aos tons puros. Conclusão: A fístula labiríntica deve ser descartada antes do procedimento cirúrgico, particularmente nos casos de colesteatomas epitimpânicos posteriores e de dupla via. A tomografia computadorizada é uma boa modalidade diagnóstica para a fístula do canal semicircular lateral. A perda auditiva neurossensorial pode ocorrer pós-cirurgicamente, mesmo em pacientes previamente não afetados, a despeito da técnica empregada.

Alteração auditiva em osteogênese imperfeita: revisão sistemática de literatura / Auditory alteration in osteogenesis imperfecta: systematic literature review

RESUMO Objetivos Analisar as publicações científicas sobre audição em indivíduos com osteogênese imperfeita. Estratégias de pesquisa Trata-se de revisão sistemática de literatura. Foram selecionados os descritores Hearing OR Hearing Loss AND Osteogenesis Imperfecta. Duas revisoras consultaram as bases de dados Cochrane Library, PubMed, LILACS, Scopus e Embase. Critérios de seleção utilizaram-se os Descritores em Ciências da Saúde, não sendo delimitado período de publicação dos estudos. Foram critérios de inclusão estudos de coorte, seguimento, transversais, casos controle e em idioma inglês. Foram critérios de exclusão artigos editoriais, relatos/séries de casos, resumos de eventos e estudos conduzidos em animais. Os estudos selecionados foram analisados pela Iniciativa STROBE e pelo Sistema GRADE. Resultados Dos 652 estudos obtidos, foram selecionados 16. A perda auditiva do tipo condutiva foi o tipo mais comum na população com osteogênese imperfeita (OI) e seu início ocorre por volta da segunda década de vida. A definição e a classificação para aferição de perda auditiva, nas publicações com a população com osteogênese imperfeita, apresentaram discordância entre os estudos. Conclusão Esta revisão respondeu às perguntas a que se propôs, constatando que as alterações audiológicas encontradas em pacientes com OI são do tipo condutivo, neurossensorial e misto. Alterações condutivas são mais comuns em pacientes mais jovens e alterações neurossensoriais, em pacientes mais velhos. A Iniciativa STROBE apontou itens descritos de forma parcial e o Sistema GRADE concluiu que os estudos apresentaram alguma falha metodológica.

ABSTRACT Purpose To analyze scientific publications on the hearing issue of patients with osteogenesis imperfecta. Reserch strategy This study is a systematic literature review. The following descriptors were selected "Hearing" OR "Hearing Loss" AND "Osteogenesis Imperfecta". Two reviewers searched the Cochrane Library, Pubmed, Latin American and Caribbean Health Sciences Literature, Scopus and Embase databases. Selection criteria Descriptors in Health Sciences were used and the publication period of studies was not limited. Inclusion criteria were cohort, follow-up, cross-sectional, and control studies in English language. Exclusion criteria were editorial articles, case reports, case summaries, and animal studies. Selected studies were analyzed by the STROBE Initiative and the GRADE System. Results Of the 652 studies, 16 were selected. Conductive hearing loss is the most common type in the osteogenesis imperfecta (OI) population and its onset is around the second decade of life. Definition and classification for hearing loss measurement in publications with the osteogenesis imperfecta population present disparities among studies. Conclusion This review met the objectives proposed, concluding that audiological alterations found in OI patients are of conductive, sensorineural and mixed types; conductive alterations are more common in younger patients and sensorineural alterations in older ones. The STROBE initiative partially pointed out described items and the GRADE system concluded that studies present some methodological failure.

Correlation between cognitive functions and central auditory processing in adolescents with non-cholesteatomatous chronic otitis media / Correlação entre funções cognitivas e processamento auditivo central em adolescentes com otite média crônica não colesteatomatosa

Abstract Auditory deprivation associated with early otitis media with effusion has been considered a risk factor for central auditory processing (CAP), as well as for the development of a number of cognitive functions. Objective: To study the neuropsychological functions of attention, working memory and executive function in adolescents with and without non-cholesteatomatous chronic otitis media (NCCOM) and analyze their interrelationships with the behavioral evaluation of CAP. Methods: Sixty-eight adolescents were recruited, 34 were diagnosed with NCCOM (study group - SG), and 34 had no otological history (control group - CG). The Neupsilin Brief Neuropsychological Assessment Instrument was used. CAP was assessed by: Masking Level Difference, Synthetic Sentence Identification, Random Gap Detection Test, Duration Pattern Sequence Test and Dichotic Digits Test. Results: The results of Neupsilin showed lower scores in the study group when compared to the control group on the following tests: digit sequence repetition, ascending digit ordering, auditory sentence span, and phonemic verbal fluency. An association was found between central auditory processing tests and Neupsilin subtests. Conclusion: The effects of NCCOM on attention, memory and executive function related to central auditory processing disorder in adolescents seem to be enhanced by the severity of the disease.

Resumo A privação auditiva associada à otite média precoce com efusão tem sido considerada um fator de risco para o processamento auditivo central (CAP), bem como para o desenvolvimento de diversas funções cognitivas. Objetivo: Estudar as funções neuropsicológicas da atenção, memória de trabalho e função executiva em adolescentes com e sem otite média crônica não-colesteatomatosa (NCCOM) e analisar suas inter-relações com a avaliação comportamental da PAC. Métodos: Sessenta e oito adolescentes foram recrutados, 34 foram diagnosticados com NCCOM (grupo de estudo - GE) e 34 não tinham história otológica (grupo controle - GC). Utilizou-se o Instrumento de Avaliação Neuropsicológica Breve de Neupsilin. O CAP foi avaliado por: Diferença de Nível de Mascaramento, Identificação de Frase Sintética, Teste de Detecção de Intervalo Aleatório, Teste de Sequência de Padrão de Duração e Teste de Dígitos Dicóticos. Resultados: Os resultados de Neupsilin mostraram menores escores no grupo de estudo quando comparados ao grupo controle nos seguintes testes: repetição de sequência de dígitos, ordenação de dígitos ascendentes, extensão de sentenças auditivas e fluência verbal fonêmica. Foi encontrada uma associação entre os testes do processamento auditivo central e os subtestes de Neupsilin. Conclusão: Os efeitos do NCCOM na atenção, memória e função executiva relacionados ao transtorno do processamento auditivo central em adolescentes parecem ser potencializados pela gravidade da doença.

Characteristics of 419 patients with acquired middle ear cholesteatoma / Características de 419 pacientes com colesteatoma adquirido de orelha média

Abstract Introduction: Cholesteatoma is a destructive lesion that can result in life-threatening complications. Typically, it presents with hypoacusis and continuous otorrhea as symptoms. Because it is a rare disease, there are few studies in Brazil describing the characteristics of patients with the disease. Objective: This study aimed to determine the prevalence of cholesteatoma in patients with chronic otitis media and describe clinical, audiological and surgical characteristics of patients with acquired middle ear cholesteatoma treated at a referral hospital in the public health system. Methods: Cross-sectional and prospective cohort study, including 1710 patients with chronic otitis media, treated between August 2000 and June 2015, without prior surgery. Detailed clinical history, videotoscopy, and audiometry were performed, in addition to review of medical records to search for surgical data. Cholesteatomas were classified according to their route of formation. Results: Of the patients with chronic otitis media, 419 (24.5%) had cholesteatoma; mean age of 34.49 years; 53.5% female and 63.8% adults. Bilateral cholesteatoma was observed in 17.1%. Anterior epitympanic cholesteatoma corresponded to 1.9%; posterior epitympanic, 32.9%; posterior mesotympanic, 33.7%; two routes, 14.8%; and indeterminate, 16.7%. The mean air-bone gap was 29.84 dB and did not differ between routes of formation. There were no correlations between gap size and patient age or duration of symptoms. Of the surgical cases, 16.8% underwent closed tympanomastoidectomy and 75.2% open tympanomastoidectomy. Conclusion: The prevalence of cholesteatoma in patients with chronic otitis media was 24.5% and it was more common in adults than in children. Posterior mesotympanic cholesteatoma was more frequent, with no difference in mean air-bone gap between the different routes of formation. In patients undergoing surgery, open tympanomastoidectomy was the procedure most frequently chosen.

Resumo Introdução: Colesteatoma é uma lesão destrutiva que pode levar a complicações potencialmente letais. Tipicamente, apresenta hipoacusia e otorreia contínua como sintomas. Por ser uma doença rara, existem poucos estudos no Brasil que descrevam as características destes pacientes. Objetivo: O presente estudo teve como objetivos determinar a prevalência de colesteatoma entre os pacientes com otite média crônica (OMC) e descrever as características clínicas, audiológicas e cirúrgicas dos pacientes com colesteatoma adquirido de orelha média atendidos em um hospital de referência do sistema público de saúde. Método: Estudo transversal e de coorte prospectivo, incluindo 1.710 pacientes com OMC, atendidos entre agosto de 2000 e junho de 2015, sem tratamento cirúrgico prévio. Foram feitas anamnese detalhada, videotoscopia e audiometria, além de revisão de prontuários para busca de dados cirúrgicos. Os colesteatomas foram classificados conforme sua via de formação. Resultados: Dos pacientes com otite média crônica, 419 (24,5%) apresentavam colesteatoma. Média de 34,49 anos; 53,5% do sexo feminino e 63,8% adultos. Colesteatoma foi observado bilateralmente em 17,1%. Os epitimpânicos anteriores corresponderam a 1,9%; os epitimpânicos posteriores a 32,9%; os mesotimpânicos posteriores a 33,7%; duas vias a 14,8% e indeterminados a 16,7%. A média tritonal dos gaps aeroósseos foi de 29,84 dB e não diferiu entre os grupos segundo as vias de formação. Não foram observadas correlações entre tamanho do gap e idade do paciente ou duração dos sintomas. Dos pacientes operados, 16,8% foram submetidos a timpanomastoidectomia fechada e 75,2% a timpanomastoidectomia aberta. Conclusão: A prevalência de colesteatoma em pacientes com otite média crônica foi de 24,5% e foi mais frequente em adultos do que em crianças. Os mesotimpânicos posteriores foram mais frequentes, não foi observada diferença na média dos gaps aeroósseos entre diferentes vias de formação. Nos pacientes submetidos a cirurgia, a timpanomastoidectomia aberta foi o procedimento escolhido.

Assessment of Eustachian tube function in patients with tympanic membrane retraction and in normal subjects / Avaliação da função da tuba de Eustáquio em pacientes com retração de membrana timpânica e em indivíduos normais

Abstract Introduction The diagnosis of Eustachian tube dysfunctions is essential for better understanding of the pathogenesis of chronic otitis media. A series of tests to assess tube function are described in the literature; however, they are methodologically heterogeneous, with differences ranging from application protocols to standardization of tests and their results. Objective To evaluate the variation in middle ear pressure in patients with tympanic membrane retraction and in normal patients during tube function tests, as well as to evaluate intra-individual variation between these tests. Methods An observational, contemporary, cross-sectional study was conducted, in which the factor under study was the variation in middle ear pressure during tube function tests (Valsalva maneuver, sniff test, Toynbee maneuver) in healthy patients and in patients with mild and moderate/severe tympanic retraction. A total of 38 patients (76 ears) were included in the study. Patients underwent tube function tests at two different time points to determine pressure measurements after each maneuver. Statistical analysis was performed using SPSS software, version 18.0, considering p-values <0.05 as statistically significant. Results Mean (standard deviation) age was 11 (2.72) years; 55.3% of patients were male and 44.7% female. The prevalence of type A tympanogram was higher among participants with healthy ears and those with mild retraction, whereas type C tympanograms were more frequent in the moderate/severe retraction group. An increase in middle ear pressure was observed during the Valsalva maneuver at the first time point evaluated in all three groups of ears (p = 0.012). The variation in pressure was not significant either for the sniff test or for the Toynbee maneuver at the two time points evaluated (p ≥ 0.05). Agreement between measurements obtained at the two different time points was weak to moderate for all tests in all three groups of ears, and the variations in discrepancy between measurements were higher in ears with moderate/severe tympanic retraction. Conclusion In this study population, the mean pressure in the middle ear showed significant variation only during the Valsalva maneuver at the first time point evaluated in the three groups of ears. Normal ears and those with mild retraction behaved similarly in all tests. The tested maneuvers exhibited weak to moderate intra-individual variation, with the greatest variation occurring in ears with moderate/severe retraction.

Resumo Introdução O diagnóstico das disfunções da tuba auditiva é essencial para o melhor entendimento da patogênese da otite média crônica. A literatura descreve uma série de testes que avaliam a função tubária; contudo, tais exames são metodologicamente heterogêneos, com diferenças que variam desde os protocolos de aplicação até a padronização dos exames e seus resultados. Objetivo Avaliar a variação na pressão na orelha média em pacientes com retração da membrana timpânica e em indivíduos normais durante os testes de função tubária e também avaliar a variação intraindividual desses testes. Método Estudo observacional do tipo transversal e contemporâneo, no qual o fator em estudo foi a variação na pressão na orelha média durante os testes de função tubária (manobra de Valsalva, Sniff Test e manobra de Toynbee) em indivíduos normais e em pacientes com retrações timpânicas leves e moderadas/graves. Foram incluídos 38 pacientes (76 orelhas). Os pacientes foram submetidos, em dois momentos diferentes, a testes de função tubária para determinar as medidas de pressão após cada manobra. A análise estatística foi feita com o programa SPSS, versão 18.0, e consideramos como estatisticamente significativos os valores de p < 0,05. Resultados A média ± desvio padrão da idade foi de 11 ± 2,72 anos; 55,3% dos pacientes eram do gênero masculino e 44,7% do feminino. A prevalência de curvas timpanométricas do tipo A foi mais alta entre os participantes com orelhas normais e naqueles com retrações leves, enquanto as curvas timpanométricas do tipo C foram mais frequentes no grupo com retrações moderadas/graves. Observamos pressões aumentadas na orelha média durante a manobra de Valsalva no primeiro momento da avaliação nos três grupos de orelhas (p = 0,012). A variação na pressão não foi significativa para o Sniff Test, nem para a manobra de Toynbee nos dois momentos de avaliação (p ≥ 0,05). Consideramos que a concordância entre as determinações obtidas nos dois momentos diferentes foi fraca a moderada para todos os testes nos três grupos de orelhas e as variações em termos de discrepância entre as medidas foram maiores nas orelhas com retrações timpânicas moderadas/graves. Conclusão Na população estudada, a média das pressões na orelha média apresentou variação significante apenas durante a manobra de Valsalva no primeiro momento de avaliação, nos três grupos de orelhas. As orelhas normais e aquelas que apresentavam retração leve se comportaram de maneira similar nos testes. As manobras testadas exibiram uma variação intraindividual fraca a moderada e a maior variação ocorreu nas orelhas com retrações moderadas/graves.

Aplicabilidade do Mismatch Negativity na população infantil: revisão sistemática de literatura / Applicability of Mismatch Negativity in the child population: systematic literature review

RESUMO Introdução Mismatch Negativity (MMN) é um potencial eletrofisiológico que mede a habilidade do cérebro em discriminar sons, independente da capacidade atencional e comportamental. Por ser uma medida objetiva e de fácil utilização, torna-se promissora no estudo da investigação do processamento auditivo em crianças. Objetivo Verificar a aplicabilidade do Mismatch Negativity na população infantil. Estratégia de pesquisa Conduziu-se uma busca nos meses de agosto e setembro de 2016, usando os descritores Evoked Potentials, Auditory AND Children, Event-related Potential AND Children e Electrophysiology AND Children, nas bases de dados Portal BVS (MEDLINE, IBECS e LILACS) e SciELO. Critérios de seleção Foram selecionados artigos em português, inglês e espanhol, publicados até setembro de 2016, sem limitação de data inicial, cuja abordagem do Mismatch Negativity fosse com a população infantil. Resultados A estratégia de busca resultou na seleção de 23 artigos, classificados como artigos originais. Os estudos evidenciaram diversas aplicabilidades do MMN em crianças, incluindo transtorno do espectro autista, transtornos do processamento auditivo, fissura labiopalatina, prematuridade e distúrbio específico de linguagem, sendo a maioria em dislexia. Conclusão Apesar da grande variabilidade envolvida nas medidas de realização do MMN, existe uma ampla aplicabilidade clínica desse potencial eletrofisiológico na população infantil.

ABSTRACT Introduction Mismatch Negativity (MMN) is an electrophysiological potential that evaluates the brain's capacity to discriminate sounds, regardless of attentional and behavioral capacity. Because it is an objective and user-friendly measure, it becomes promising in the study of auditory processing research in children. Purpose To verify the applicability of Mismatch Negativity (MMN) in children. Research strategy A search was conducted in August and September 2016 using the descriptors Evoked Potentials, Auditory AND Children, Event-related Potential AND Children and Electrophysiology AND Children in bibliographic collection of the electronic databases Portal BVS (Medline, IBECS and LILACS) and SciELO. Selection criteria The selection of articles was carried out in Portuguese, English and Spanish published up to September 2016 without initial date limitation and whose approach to Mismatch Negativity was with the child population. Results The search strategy resulted in the selection of 23 articles classified as original articles. The studies evidenced several applications of MMN in children, including autism spectrum disorder, auditory processing disorders, cleft lip and palate, prematurity, and language-specific disorder, being the majority of them in dyslexia. Conclusion Despite the great variability involved in the measures of MMN, there is a wide clinical applicability of this electrophysiological potential in the infant population.

An experimental model of chronic rhinosinusitis in rabbits without bacterial inoculation

PURPOSE: Evaluate and compare two different experimental techniques of maxillary sinus ostium occlusion using N-butyl cyanoacrylate in developing chronic histological findings without the inoculation of pathogenic bacteria among rabbits. METHODS: In a randomized study, sixteen New Zealand rabbits were assigned for occlusion of the right maxillary sinus through a transmaxillary approach or through the roof of the nasal cavity. The contralateral sinus served as a control. After 12 weeks, the animals were sacrificed for blinded histopathological analysis of the maxillary sinus mucosa. RESULTS: Histopathological changes consistent with CRS were found in eight (100%) of the maxillary sinuses approached transmaxillary and three of those through the roof of the nasal cavity (37.5%), p 0.008 and 0.250, respectively, comparing with the control side. Chronic mucosal changes were significantly better induced using the transmaxillary approach (p 0.026). CONCLUSION: It is possible to induce a model of chronic sinusitis among rabbits with transmaxillary sinus occlusion without bacterial inoculation. This model can be replicated for future cellular studies. .

Caracterização do posicionamento e ação motora de língua em pacientes com fissura labiopalatina em um serviço de referência de Porto Alegre / Characterization of the positioning and motor action of the tongue in patients with cleft lip and palate in a reference service in Porto Alegre

Introdução: As fissuras labiopalatinas apresentam-se como a anomalia congênita mais frequente na face, ocorrendo como transtornos isolados ou associados a outras anormalidades, podendo repercutir em alterações fonoaudiológicas ligadas à fala e motricidade orofacial. Este estudo objetivou caracterizar aspectos do exame orofacial correlacionando o tipo de fissura com o posicionamento de língua em repouso e na deglutição, bem como seu desempenho na realização de praxias orofaciais, em sujeitos com fissura labiopalatina acompanhados no Serviço de Cirurgia Plástica Craniomaxilofacial do Hospital de Clínicas de Porto Alegre (HCPA). Métodos: Trata-se de um estudo transversal, realizado por meio de pesquisa documental, realizada nos registros dos prontuários de casos de fissura labiopalatina, atendidos no HCPA.Dos 123 prontuários selecionados, foram estratificados dados de 34 pacientes, por apresentarem avaliação orofacial completa nos aspectos selecionados. Resultados: Prevaleceu a fissura labiopalatal unilateral (32,4%), havendo predomínio discreto do sexo masculino (55,9%) e faixa etária de 6 a 10 anos de idade (26,5%). A posição de língua no repouso manifestou-se alterada na maioria dos casos apresentados, bem como na função de deglutição. A limitação e assimetria de língua na realização das praxias orofaciais manifestaram-se igualmente na maioria dos casos. Conclusão: Não foi encontrada associação estatística significativa quando relacionada à classificação das fissuras com a postura de língua na deglutição, postura de língua nas praxias e respiração. Contudo, correlacionaram-se as fissuras labiais unilaterais e palatais apenas com a postura da língua em repouso na papila palatina, o mesmo apresentou relação estatisticamente significativa (p 0,008)

Introduction: Cleft lip and clef palate are the most common congenital anomalies of the face, occurring as isolated disorders or in association with other abnormalities, which may lead to speech-language disorders related to orofacial changes. This study aimed to characterize aspects of the orofacial examination by correlating cleft type with the positioning of the tongue at rest and during swallowing, as well as performance of orofacial movements, in subjects with cleft lip/palate cared for at the Department of Plastic Craniomaxilofacial Surgery of the Hospital de Clinicas of Porto Alegre (HCPA). Methods: This was a cross-sectional study based on an analysis of the medical records of cases of cleft lip/palate treated at the HCPA. Of the 123 records selected, we stratified data of 34 patients who had undergone complete orofacial evaluation in selected aspects. Results: Unilateral cleft lip and palate prevailed (32.4%), with a slight predominance of males (55.9%) and the 6-10-year age bracket (26.5%). In most of the cases, the resting position of the tongue as well as the swallowing function were found to be changed. Limitation and asymmetry of the tongue in performing orofacial movements were seen in most cases as well. Conclusion: There was no statistically significant association as related to the classification of the clefts with the positioning of the tongue in swallowing, tongue posture during movements, and breathing. However, unilateral cleft lip and palate correlated only with resting tongue posture in the palatine papilla, which was statistically significant (p 0.008)
