    Humanity is being affected by the SARS-CoV-2 beta-coronavirus since December 2019. This disease has caused a high mortality rate due to easy contagion in pandemic mundial scale. The transmission occurs from human to human, through respiratory droplets and contact with aerosol-infected surfaces. Anyone carrying the virus that is close (i.e. less than 1 meter) to another person’s eyes, nose or mouth, makes him/her susceptible because of direct contact with the contaminated particles he/she will have (e.g. by touching an infected surface and then touching the eyes, nose or mouth). Due to the risk of exposure to infection, given the forms of contamination by this virus and considering measures to control and protect against infections by health professionals, the Academic Rehabilitation League (LAR), formed by professors and students of the University Center of Americas, produced 400 facial protectors using 3D printing through models composed of polymer filaments, in addition to the acetate films visor and elastics for better fixation, these can be reused and sterilized easily. The masks were distributed free of charge to health professionals in the state of São Paulo, with the purpose of offering greater support, so that they can perform their work safely.</jats:p

    RESUMO: Objetivo: caracterizar os tipos de erros cometidos no teste Staggered Spondaic Words por pacientes submetidos à avaliação do processamento auditivo e correlacioná-los com idade, sexo, escolaridade e subperfil de alteração. Métodos: foram incluídos os testes Staggered Spondaic Words pertencentes a um banco de dados particular, realizados em pacientes de 7 a 19 anos de idade, no período de junho de 2011 a setembro de 2013. Resultados: os tipos de erros mais frequentes foram: omissão de palavra (76,66%), substituição de palavra (45%) e substituição por palavra adjacente (20%). O subperfil de alteração encontrado foi decodificação acompanhado de integração (38,33%), seguido de decodificação (23,33%), resultado normal (20%), e outros (18,34%). Na comparação entre as condições, observou-se maior número de erros nas competitivas. Em relação à idade e à escolaridade, os erros ocorreram em maior número entre pacientes de menor idade e menor escolaridade. A correlação entre o número total de erros e a variável sexo não foi estatisticamente significante. Conclusão: foi possível caracterizar os tipos de erros cometidos no teste Staggered Spondaic Words, correlacioná-los às variáveis propostas (sexo, idade, escolaridade e subperfil de alteração) e ressaltar a importância deste teste, que é um dos mais utilizados para avaliar o processamento auditivo, para o diagnóstico dos transtornos da comunicação humana e na identificação de crianças com risco para transtornos de aprendizagem

    ABSTRACT Purpose To analyze the latency and amplitude of P300 responses obtained with electrodes positioned at Cz and Fz and in different tasks of infrequent stimulus identification in normal hearing individuals. Methods Forty adults of both genders participated in the study. Three recordings with three different tasks were obtained for the identification of the infrequent stimulus; simultaneous recordings were obtained from Cz and Fz positions. Results Cz position showed significantly greater amplitudes and lower latencies than Fz. Regarding the three tasks, only &#8220;pronouncing the word &#8217;thin&#8217;&#8221; was different from &#8220;raising a finger&#8221;, with lowest latencies for the verbal task. Regarding amplitude, significantly higher values were observed for &#8220;raising a finger&#8221;, followed by &#8220;pronouncing the word &#8216;thin&#8217;&#8221; and mental counting. Conclusion Cz obtained the best values, highest amplitude and lowest latency. Lowest latencies were obtained for the task of &#8220;pronouncing the word &#8216;thin&#8217;&#8221; and the highest amplitudes were obtained for &#8220;raising a finger&#8221;
