O Lúpus Eritematoso Sistêmico (LES) é uma doença inflamatória crônica sistêmica, de etiologia desconhecida, multifatorial, caracterizada imunologicamente pela presença de múltiplos auto-anticorpos, sendo as manifestações clínicas bastante polimórficas. Essa doença pode comprometer múltiplos órgãos e sistemas. Os comprometimentos mais comuns são: articular, cutâneo, vascular, renal, neurológico, cardíaco, gastrointestinal, hematológico, ocular e auditivo. OBJETIVO: Investigar a função auditiva central de indivíduos com Lúpus Eritematoso Sistêmico. MATERIAL E MÉTODO: Foi realizado estudo de série, no qual foram avaliados 60 indivíduos do sexo feminino, com idades entre 21 a 46 anos, sendo 30 no grupo controle e 30 no grupo pesquisa. Os participantes foram submetidos a Anamnese, Avaliação Audiológica (Audiometria Tonal, Logoaudiometria e Medidas de Imitância Acústica), e pesquisa dos Potenciais Evocados Auditivos de Curta (PEATE), Média (PEAML) e Longa Latências (PEALL). Os dados obtidos foram analisados estatisticamente. RESULTADOS: Não foram observadas diferenças estatisticamente significantes entre os dois grupos avaliados, em nenhuma das avaliações realizadas. CONCLUSÕES: Não há diferença nos Potenciais Evocados Auditivos de Curta (PEATE), Média (PEAML) e Longa Latência (P300) entre os indivíduos dos grupos controle e pesquisa. Systemic lupus erythematosus (SLE) is a multifactorial chronic systemic inflammatory disease, of unknown origin, characterized by the presence of autoantibodies and polymorphic clinical manifestations. This disease may involve multiple organs and systems. The most common findings are articular, cutaneous, vascular, renal, neurological, cardiac, gastrointestinal, hematological, ocular, and auditory abnormalities. AIM: To investigate the central auditory function of subjects diagnosed with Systemic Lupus Erythematosus (SLE). MATERIAL AND METHOD: A time-series study was made of sixty subjects, aged between 21 and 46 years, which were divided into a control (n=30) and an experimental group (n=30). A clinical history, audiological evaluation (pure tone audiometry, speech audiometry and immitance testing) and short (ABR), middle (MLR) and long latency (LLAEP) potentials were carried out in all subjects. RESULTS: No statistically significant differences were observed between the groups in any of the evaluations. CONCLUSIONS: In this study there were no differences in short, middle and long latency auditory potentials between the control and experiment subject groups.

Introduction: In patients with multiple sclerosis among other symptoms occur cognitive dysfunctions, which can be shown by P300 wave changes. Goal: The aim of this study was to demonstrate that patients with multiple sclerosis have reduced amplitude and prolonged latency, longer than 300 ± 10 ms. Methods: The study included group of patients with multiple sclerosis and control group. After reviewing the medical records both groups of 14 participants were subjected to the same testing procedures auditory cognitive potentials (P300). Results: We have shown that patients with multiple sclerosis don’t have prolonged P300 target stimulus latency, but they have a longer P300 frequent stimulus latency for 18 ms. From 14 patients seven had a pathological P300 target stimulus amplitude, and even 12 patient had pathological P300 frequent stimulus amplitude. Conclusion: People with multiple sclerosis have altered P300 which indicates the presence of cognitive dysfunction in these patients.

OBJETIVO: Analisar os potenciais evocados auditivos de tronco encefálico em usuários de crack e múltiplas drogas, bem como levantar as possíveis queixas auditivas e de equilíbrio nesta população. MÉTODOS: Foram avaliados 40 usuários de drogas (20 com uso há mais de cinco anos e 20 há menos de cinco anos) e 20 não usuários, do sexo masculino, com idades entre 19 e 46 anos, com limiares auditivos dentro da normalidade. RESULTADOS: Não houve diferenças significativas dos potenciais evocados auditivos de tronco encefálico dos usuários de drogas quando comparados ao grupo controle. CONCLUSÃO: Os potenciais evocados auditivos de tronco encefálico dos usuários de drogas não diferiram significantemente do grupo controle. As queixas apresentadas pelos usuários de drogas foram hiperacusia, alucinação auditiva, zumbido e alteração de equilíbrio. PURPOSE: To study the findings of auditory brainstem evoked potentials in crack and multiple drugs users, as well as to raise possible auditory and balance complaints in this population. METHODS: A total of 40 drugs addicts (20 who had been using drugs for over five years and 20 for less than five years) and 20 non-users were evaluated. Subjects were all male, with ages ranging from 19 to 46 years, and had auditory thresholds within normal. RESULTS: No significant statistical differences were found regarding the auditory brainstem evoked potentials findings of the addicts group, when compared to the non-users. CONCLUSION: Auditory brainstem evoked potentials in crack and multiple drugs users did not differ significantly from the control group. Complaints presented by drugs addicts were hyperacusis, auditory hallucination, tinnitus and altered balance.
