BackgroundThe use of Auditory Steady-State Responses (ASSRs) for auditory screening in school-aged children, particularly in children who are difficult to test and children with disabilities, has not been explored yet. This pilot study investigated the use of ASSR for auditory screening in school-aged children.Materials and methodsA cross-sectional pilot study of 23 children aged 9 to 11 with normal-hearing thresholds and seven age-matched children with permanent moderate-to-profound bilateral hearing loss were examined. The tested carrier frequencies were 500, 1,000, 2,000, and 4,000 Hz, and the stimulus was modulated between 77 and 107 Hz. The ASSRs decreased according to the tested intensity levels of 50, 40, and 30 dB sound pressure level (SPL). Sensitivity and specificity were estimated from the responses of the children with normal hearing and those with hearing loss.ResultsFor the children with normal hearing, the 2,000-Hz frequency was detected more often in both ears and at all intensity levels compared to the other frequencies. The 500- and 2,000-Hz frequencies resulted in different response patterns in both ears. The time until response detection increased in parallel with amplitude reduction, as expected. The overall time required for the test was 15 minutes, including the time spent in volunteer preparation. The sensitivity was 97% for the three intensities, and the best specificity value was 100%, which was observed at 50 dB.DiscussionThe response analysis indicated that a screening protocol for school-aged children could include 1,000, 2,000, and 4,000 Hz and that the recording of ASSRs was highly sensitive to internal and external factors. Fifty dB SPL should be considered a cut-off criterion for screening purposes because this was the intensity level with a sensitivity of 97% and a specificity of 100%.ConclusionThe use of ASSRs might be particularly useful in school-aged children who have difficulty performing subjective hearing tests. The sensitivity and specificity data suggested that the use of ASSRs was feasible as an auditory screening tool. In order to determine a protocol for screening, future studies should include a larger sample and children with mild hearing loss.
Este estudo tem como tema a análise do estado da arte sobre saúde auditiva no Brasil e a investigação da construção da produção científica nesta área. O objetivo é descrever, analisar e construir a linha histórica da produção científica em saúde auditiva no Brasil, no período de 2000 a 2010, tendo como referência a implantação, desenvolvimento e avaliação da política de Saúde Auditiva no contexto do Sistema Único de Saúde (SUS). As primeiras publicações encontradas são do ano de 2005. Com o passar dos anos, principalmente nos dois últimos, o número de publicações cresceu gradativamente. O eixo temático com maior número de artigos relacionados foi Usuários. O tema avaliação, com enfoque na satisfação do usuário, foi o mais abordado. Os temas gestão e capacitação de profissionais também foram recorrentes.
Conflict of interest: non-existent state Departments of Health, had to reformulate the health management practices 1 .Management is understood as administration, optimization of productivity and decision making that contributes to the effectiveness/efficiency of the organisation 2 . For the application of these concepts to health management, it is necessary, in addition to ensure the compliance with the universal principles of the SUS, to enable the professional and popular participation in the decisions about the health services and ensure high productivity of the implemented actions 2 . However, to achieve these objectives, the management within the public health agencies must follow certain stages that organize the implementation of internal actions in the institution.The management can be divided into three stages: planning, implementation and evaluation of actions. The planning should establish a coordinated set of actions to achieve a certain objective 3 ; ABSTRACT Purpose: to relate the communicative strategies adopted in the management of a health institution with the communication perception of the participants. Methods: descriptive-comparative and crosssectional study with a sample defined by type. 56 subjects from six sectors of the institution were interviewed with a closed questions questionnaire. For this study, we analyzed the questions related to stages of management and perception of communication at work. Results: most of the respondents reported that the meetings in which planning occurs are not exclusive to this activity. The direct supervisors are always present, as opposed to the indirect ones. Regarding the implementation of actions, it was observed that all members of the sector take responsibility for the activities and share information during the process. It was reported that the evaluation occurs in an unsystematic way and the presence of direct and indirect leadership is similar to what occurs in the planning stage. It was found a low degree of correlation between the answers. The perception of the subjects about the communication was adequate, noting that no direct relationship is established between the communication and work process. Conclusion: it is considered that the data obtained in this study were relevant, so that led to discuss the role of communication in the system manager searched.
O mercado de shows internacionais tem apresentado grande crescimento no Brasil, e Belo Horizonte começou a figurar na rota destes eventos, que tem sido realizados em outras cidades fora do eixo Rio-São Paulo. Neste contexto, o presente trabalho tem como objetivo estudar e compreender o mercado de shows internacionais em Belo Horizonte, visando a contribuir para o desenvolvimento e fortalecimento desse nicho mercadológico na cidade e auxiliar nos processos de planejamento e produção dos shows. O instrumento metodológico adotado foi a pesquisa de mercado, que incluiu entrevistas em profundidade com produtores de shows internacionais da cidade e pesquisa quantitativa aplicada ao público. A partir dos resultados alcançados, foi possível inferir que, atualmente, o mercado de shows internacionais em Belo Horizonte apresenta pouca margem de crescimento, devido a fatores que envolvem o poder público, a escassez de patrocínios e a interferência de uma série de condicionantes à presença do público nos shows. Entretanto, a realização de ações de formação de público, parcerias entre produtoras e poder público e investimento e inovação em ações de comunicação e marketing melhor direcionadas ao público-alvo poderiam ser os primeiros passos para mudar a atual realidade. Por último, destaca-se a importância do instrumento pesquisa de mercado como ferramenta valiosa para o planejamento de eventos, já que esta possibilita o conhecimento dos hábitos, preferências e poder de compra do público, o que pode auxiliar na realização das atividades de produção e no crescimento e desenvolvimento do mercado local.
