The aim of this study was to investigate the vestibular system in a Type 1 Diabetic mellitus population, justifying its accomplishment for the narrow relation existing between the metabolic disturbances and vestibular and/or auditory alterations and the great prevalence of these disturbances in general population. The present study was developed in the Otology Health Clinic of the Santa Maria University Hospital (HUSM), according to the approval of the Research Ethic Committee of the Sciences Health Center from Santa Maria Federal University (UFSM). 19 individuals, being 10 of the female gender (52,6%) and 9 of the male gender (47,3%), with ages varying of 8 to 25 years old, with medical diagnosis of Type 1 Diabetes mellitus. For comparison of the results, a control group was selected with others 19 individuals, equalizing itself age and sex. These individuals should not complaint about auditory or vestibular disturbances, as well as Type 1 Diabetes mellitus diagnosis or other illnesses that could affect the evaluation. The evaluation protocol consisted of anamnese, otoscopic inspection, basic audiologic evaluation, dynamic and static balance evaluation, cerebellar tests and vectoeletronystagmographic evaluation. Alteration in the vectoeletronystagmographic evaluation were found in 36,84% (n=7) Type 1 Diabetes mellitus individuals, being 21.06% (n=4) Periferic Deficitary Vestibular Syndrome and 15.79% (n=3) Periferic Irritativ Vestibular Syndrome. We conclude that Type 1 Diabetes mellitus can affect the vestibular organ. We suggest that be include in the routine evaluation of patients suffering from this disturbance, the vestibular evaluation and the accomplishment of more researchs with a larger population, to deep the knowledge regarding the alterations type that can occur related to Diabetes time. / Este estudo foi desenvolvido com o objetivo de investigar o aparelho vestibular em uma população de indivíduos portadores de Diabetes mellitus tipo 1, justificando-se sua realização pela estreita relação existente entre os distúrbios metabólicos e as alterações vestibulares e/ou auditivas e a grande prevalência destes distúrbios na população em geral. O presente estudo foi desenvolvido no Ambulatório de Otologia do Hospital Universitário de Santa Maria (HUSM), em conformidade com a aprovação do Comitê de Ética em Pesquisa do Centro de Ciências da Saúde da Universidade Federal de Santa Maria (UFSM). Foram avaliados 19 indivíduos, sendo 10 do gênero feminino (52,6%) e 9 do gênero masculino (47,3%), com idades variando de 8 a 25 anos, com diagnóstico médico de Diabetes mellitus tipo 1. Para comparação dos resultados, foi selecionado um grupo controle com outros 19 indivíduos, equiparando-se idade e sexo. Estes indivíduos não deveriam apresentar qualquer queixa auditiva ou vestibular, bem como diagnóstico de Diabetes mellitus tipo 1 ou outras doenças que pudessem interferir na avaliação. O protocolo de avaliação consistiu de anamnese, inspeção otoscópica, avaliação audiológica básica, avaliação do equilíbrio estático e dinâmico, provas cerebelares e avaliação vectoeletronistagmográfica. Encontrou-se na amostra estudada alteração a vectoeletronistagmografia em 36,84% (n=7) dos indivíduos portadores de Diabetes mellitus Tipo 1, sendo 21,06% (n=4) Síndrome Vestibular Periférica Deficitária e 15,79% (n=3) Síndrome Vestibular Periférica Irritativa. Conclui-se que o Diabetes mellitus Tipo 1 pode afetar o aparelho vestibular. Sugere-se que seja incluída na avaliação de rotina de pacientes com este distúrbio, a avaliação do aparelho vestibular e a realização de mais pesquisas com uma população maior, para aprofundar os conhecimentos a respeito dos tipos de alterações que podem ocorrer relacionadas com tempo de Diabetes.

Audiologists are challenged with various neurological diseases, such as Multiple Sclerosis. This disease causes demyelination of the white matter in the central nervous system resulting in desynchronisation of neural impulses. Despite controversy in the literature many studies illustrated some degree of auditory involvement associated with this disease. The auditory brainstem response has dominated the field during the assessment of the auditory system of patients with Multiple Sclerosis. Although this objective test procedure is useful during the assessment of the auditory nerve on a brainstem level, it reveals its own set of limitations when used in isolation as a single test procedure. A multiple test battery approach has shown promise in addressing the limitations of any single test procedure. This approach aims to assess the auditory nervous system of patients with Multiple Sclerosis on different levels (sensory and neural). The aim of the current study was to determine the effectiveness of a clinically appropriate battery of test procedures during the assessment of the auditory nervous system of 25 adult subjects with Multiple Sclerosis. The subjects were divided into two groups: Group 1 consisted of fifteen (15) subjects without a history of noise exposure, whereas the ten (10) subjects in Group 2 had previously been exposed to noise. A combined experimental-descriptive research design was selected in order to describe both the qualitative and quantitative results obtained during the study. The following test procedures were included in the test battery: • A self-assessment questionnaire allowing subjects to report on hearing abilities, related auditory-vestibular symptoms and communicative competence during every day life; • Puretone audiometry, distortion product otoacoustic emissions as well as the cochlear microphonic; and • Auditory brainstem response recording using both the rarefaction and condensation click polarities consecutively. The results indicated that a high percentage of subjects experienced vestibular symptoms such as dizziness and vertigo by the time the study was conducted. The presence of tinnitus and hearing difficulties were uncommon among subjects. Despite this, more than half of the subjects experienced difficulty with communication in the presence of background noise. Puretone audiometry demonstrated that some of the subjects presented with mild high-frequency hearing losses. However other configurations with impaired hearing thresholds were also observed. Most of the subjects’ auditory brainstem response recordings displayed abnormalities using either the rarefaction or condensation click polarity. The use of the condensation click polarity displayed more ABR abnormalities compared to the rarefaction click polarity. Several subjects displayed additional cochlear involvement while a smaller percentage of subjects presented only with neural involvement. / Dissertation (M (Communication Pathhology))--University of Pretoria, 2006. / Speech-Language Pathology and Audiology / unrestricted
