La communication d'élèves malentendants intégrés en classe ordinaire au Québec

Depuis le début des années 80, les systèmes d’éducation à travers le monde recommandent l’intégration des élèves malentendants en classe ordinaire. Malgré l’utilisation d’aides auditives et de système MF, les élèves vivent des périodes où l’amplification reçue est insuffisante ou non optimale. Ces périodes sont causées par des facteurs influençant leurs conditions de communication et cela peut nuire à leurs apprentissages. Pourtant, les études sur ces situations vécues par les élèves ont très peu considéré leur point de vue. L’étude présentée vise à 1) de documenter les perceptions des situations de communication en classe mentionnées par des élèves malentendants intégrés, appareillés et ayant un système MF décerné ou rapportées à des professionnels; 2) de comprendre le contexte dans lequel des conditions non optimales de communication surviennent; 3) d’identifier les stratégies compensatoires rapportées par l’élève ou son locuteur ou déployées lors de leur participation aux activités de classe. Cette étude de cas multiples combine des données qualitatives et quantitatives recueillies à partir d’entrevues en profondeur auprès de huit élèves malentendants, de courtes entrevues avec leur enseignant et leur intervenant principal et une session d’observation en classe au cours de laquelle le niveau de bruit a été mesuré et les positions de l’enseignant ont été notées. Les données ont été analysées de manière longitudinale afin de décrire les participants et transversale afin de les comparer. Les résultats montrent que les élèves malentendants parlent de leurs situations de communication en classe, surtout les plus difficiles en associant toutes leurs difficultés au locuteur ou au milieu et non à eux-mêmes. Pour ce qui est du contexte, des niveaux élevés de bruit ont été mesurés et les positions des enseignants montrent qu’ils sont généralement loin de l’enfant malentendant ou qu’ils ne lui font pas face. Par ailleurs, les enseignants mentionnent ne pas avoir assez d’informations pour bien venir en aide à ces élèves. Enfin, les élèves et leurs enseignants utilisent différentes stratégies de communication, mais celles-ci ne sont pas toujours efficaces pour faciliter la communication. Toutes ces constatations mènent à des pistes de solutions visant à améliorer les situations de communication en classe et le contexte dans lequel les élèves apprennent, notamment l’accroissement des connaissances des divers acteurs et de leur collaboration entre eux.

Opportunistic assessment of hearing in elderly inpatients

Objective: To determine the prevalence of occult hearing loss in elderly inpatients, to evaluate feasibility of opportunistic hearing screening and to determine subsequent provision of hearing aids. Materials and methods: Subjects (>65 years) were recruited from five elderly care wards. Hearing loss was detected by a ward-based hearing screen comprising patient-reported assessment of hearing disability and a whisper test. Subjects failing the whisper test or reporting hearing difficulties were offered formal audiological assessment. Results: Screening was performed on 51 patients aged between 70 and 95 years. Of the patients, 21 (41%) reported hearing loss and 16 (31%) failed the whisper test. A total of 37 patients (73%) were referred for audiological assessment with 17 (33%) found to have aidable hearing loss and 11 were fitted with hearing aids (22%). Discussion: This study highlights the high prevalence of occult hearing loss in elderly inpatients. Easy two-step screening can accurately identify patients with undiagnosed deafness resulting in significant proportions receiving hearing aids.

Emotion perception and talker discrimination in pediatric hearing aid users

The primary goal of this study is to examine the ability of pediatric hearing-aid listeners, with mild to moderately-severe hearing loss, to perceive emotion and to discriminate talkers. These listeners’ performance is compared to that of similarly-aged listeners with normal hearing and who use cochlear implants.

Amplificação por condução óssea em malformações congênitas: benefício e satisfação

A deficiência auditiva é um dos achados clínicos mais comuns em sujeitos com malformações de orelha. O tratamento consiste em realizar a cirurgia e/ou adaptar o aparelho de amplificação sonora por via óssea (AASI VO). A intervenção precoce é fundamental para favorecer a estimulação auditiva e desenvolvimento da fala e linguagem. OBJETIVO: Caracterizar o perfil audiológico de sujeitos com malformação congênita de orelha externa e/ou média e avaliar o benefício e a satisfação destes com o uso de AASI VO. MÉTODO: Estudo descritivo, sujeitos com malformações congênitas bilaterais de orelha externa e/ou média, deficiência auditiva condutiva ou mista, moderada ou grave e usuários de AASI VO. Avaliação do benefício utilizando teste de reconhecimento de sentenças com ruído competitivo e medidas de ganho funcional e avaliação da satisfação utilizando questionário internacional QI - AASI. RESULTADOS: Foram avaliados 13 sujeitos, sendo 61% do sexo masculino e 80% com deficiência auditiva condutiva moderada ou grave. Houve melhor desempenho na avaliação proposta na condição com AASI, quando comparada à condição sem AASI. CONCLUSÃO: Os AASI VO retroauriculares apresentaram vantagens para a população estudada e devem ser considerados como uma opção para intervenção. A satisfação foi confirmada pelos escores elevados obtidos no QI - AASI.

Surdez ocupacional em professores: um diagnóstico provável

Sintomas auditivos e ruído ambiental são freqüentemente referidos por professores, porém as aferições destes não são rotina. Forma de Estudo: Clínico prospectivo. OBJETIVOS: Estudar, em professores: os sintomas auditivos, os resultados das audiometrias e a aferição do ruído nas classes. CASUÍSTICA E MÉTODO: em dois grupos de estudo compostos por GI (40 professores) e GII (40 voluntários), estudou-se: idade, sexo, condições de trabalho, audiometrias e níveis de ruído nas classes. RESULTADOS: em GI predominaram as mulheres (86%), que atuavam em ensino fundamental (75%), em classes com 21 - 40 alunos (70%), com jornadas de trabalho de 26 a 40 horas semanais (47%), e tempo variável na profissão. 93,7% dos professores de GI referiam ruído excessivo nas classes, 65% apresentavam sintomas auditivos e 25% deles possuíam audiometrias alteradas (contra 10% de GII), predominando a gota acústica (11,25%; p<0,05). Valores de ruído de 87dBA foram aferidos em todos os níveis de ensino. CONCLUSÕES: A surdez ocupacional pode estar ocorrendo em professores, porém são necessárias pesquisas adicionais para comprovação de tal suposição.

Influence of the period after ovariectomy on femoral and mandibular bone density and on induced periodontal disease

Background: This study investigated the influence of the period after ovariectomy on femoral and mandibular bone mineral density (BMD) and on induced periodontal disease.Methods: One hundred and twenty-six female Holtzman rats were divided into nine groups: control, sham surgery (SHAM) with and without induction of periodontal disease for 51 and 150 days, and ovariectomy (OVX) with and without induction of periodontal disease for 51 and 150 days. Periodontal disease was induced by placing ligatures on the first lower molars during the last 30 days of each period. BMD was measured by dual-energy x-ray absorptiometry. Vertical bone loss was determined by measuring the distance from the alveolar bone crest to the cemento-enamel junction on the mesial side of the first lower molar.Results: Statistical analyses (Kruskal-Wallis test) revealed a significant difference between the OVX and SHAM groups' global and femoral proximal epiphysis BMD (P < 0.001) for 150 days and in the global evaluation for 51 days. For mandibular BMD, no difference was found between the groups of each period. Influence of the period on femoral BMD was found only for the SHAM groups, with lower BMD for the 51-day period compared to the 150-day period (P < 0.05). In the global evaluation of the mandible, a lower BMD was found after 51 days. The period was a contributing factor for the vertical bone loss, and it resulted in higher values for the 51-day period (P < 0.05).Conclusion: the period influenced the femoral BMD and the vertical bone loss in induced periodontal disease.
