The results showed that tobacco growers exposed to pesticides exhibited signs of central auditory dysfunction characterised by decrements in temporal processing and binaural integration processes/abilities.

RESUMO: o objetivo desse trabalho foi investigar, a partir do olhar da equipe educacional, as práticas pedagógicas no Ensino Médio e Ensino Profissionalizante quando tem em sala de aula alunos surdos. Foi realizada uma pesquisa de campo qualitativa e a coleta de informações ocorreu a partir de uma entrevista não estruturada com dois professores, dois pedagogos e um intérprete de Libras que atuam na educação de três alunos surdos do ensino regular. A pesquisa foi realizada em uma escola estadual, considerada referência para educação de surdos, de uma cidade de médio porte do interior do Paraná. O conjunto de dados foi dividido em eixos temáticos e analisados a partir do conteúdo. Os eixos temáticos norteadores da discussão são: aspectos positivos e negativos -inclusão do aluno surdo no ensino regular; metodologias de ensino usadas em sala de aula com o aluno surdo; o intérprete de Libras na escola regular. Conclui-se que a inclusão do aluno surdo está sendo realizada, mas que essa inclusão não está garantindo o acesso às aprendizagens, pois há dificuldades de comunicação entre professor e aluno surdo, falta de conhecimento sobre a surdez e adaptações metodológicas isoladas na sala de aula. Espera-se que esse estudo movimente discussões acerca da inclusão do aluno surdo no ensino regular, possibilitando a essa população um ensino que respeite a peculiaridade da surdez e dê condições para que esses sujeitos se desenvolvam e participem efetivamente do meio social em que vivem. PALAVRAS-CHAVE:Educação Especial. Surdez. Inclusão Educacional. Ensino Médio. ABSTRACT:The aim of this study was to investigate teaching practices, from the perspective of the educational team, in high school and vocational education when there are deaf students in the classroom. We conducted a qualitative field study; data collection occurred using an unstructured interview with two classroom teachers, two pedagogues and one Brazilian Sign Language (Libras) interpreter who work with three deaf students in regular education. The survey was conducted in a state school that is considered a reference in deaf education, in a medium sized city in a rural part of the state of Paraná. The dataset was divided into themes and analyzed according to content. The categorical topics under discussion were positive and negative aspects -inclusion of deaf students in regular education, teaching methodologies used in the classroom with deaf students, the Libras interpreter in regular schools. We concluded that even though the inclusion of deaf students is being carried out, access to learning is not necessarily being ensured. The reasons for this include communication difficulties between teachers and deaf students, lack of understanding about deafness and the application of isolated methodological adaptations isolated in the classroom. We hope this study will instigate further discussions about the inclusion of deaf students in regular education, enabling this group to partake in an educational experience that respects the uniqueness of deafness, and that offe...

The most evident abnormalities in the audiological evaluation were the predominance of the down-sloping audiometric configuration beginning at 4 kHz bilaterally and the bilateral absence of acoustic reflex at the frequencies of 3 and 4 kHz. In the electrophysiological evaluation, 50% of the patients showed abnormalities with prevalence of an increase of the latency of waves I, II and V and of the interval in the interpeaks I-III, I-V and III-V.

ABSTRACT The Purpose of this case report is to present four cases of tobacco growers with hearing loss due to occupational exposure to pesticides. A qualitative case study comprising three cases of sensorineural hearing loss with causal nexus (Cases 1, 2 and 4), and one (Case 3) of sensorineural hearing loss compatible with ototoxicity by pesticides, with causal nexus mainly based on minor neuropsychiatric disorders. The sample was composed of rural workers with health problems, in working age, having started working early in life, exposed to various pesticides, including organophosphates. The auditory and neurovegetative symptoms reported were noise discomfort (n = 2), speech perception difficulty (n = 3), dizziness (n = 2), and imbalance (n = 2). The pure-tone audiometry revealed a sensorineural hearing loss in one or more high frequencies, and one of the cases presented alteration in the brainstem auditory evoked potentials. There is evidence, in this study, of an association between hearing loss and work in tobacco growers exposed to pesticides, with peripheral auditory damage in four cases, and central damage in one of them. Thus, the need for a complete audiological evaluation of pesticide-exposed populations is highlighted.

Summary Introduction: The otoacoustic emissions test is an essential tool in the evaluation of auditory function, since it allows the early detection of cochlear damage of occupational origin. Objective: To present a review of the literature and analyze the effectiveness of the clinical application of the otoacoustic emissions test in workers exposed to noise. Methods: A bibliographical search covering a period of 10 years was performed in the Virtual Health Library including published articles in national and international journals indexed in the internationally recognized databases for the health sciences, LILACS, SCIELO, and MEDLINE, using the terms “otoacoustic emissions” and “occupational exposure.” The type of published article (national/international), the type and intensity of the stimulus most commonly used for the evoked otoacoustic emissions, the gender and age of the subjects, and the conclusions from the retrospective studies were all taken into consideration. Results and Conclusions: A total of 19 articles were analyzed, 7 national and 12 international, covering subjects from 17 to 77 years of age, mostly men. The type of stimulus most commonly used for the evoked otoacoustic emissions was the distortion method (12). Through this review, we have concluded that testing of evoked otoacoustic emissions in workers exposed to noise is an important tool in the early diagnosis of noise-induced cochlear hearing disorders.
