Estudo eletroneuromiografico reflexo trigemino-facial nas diferentes raças da especie humana

Orientadores: Luiz Antonio de Lima Resende, Fausto BerzinDissertação (mestrado) - Universidade Estadual de Campinas, Faculdade de Odontologia de PiracicabaResumo: Estudaram-se latências do reflexo trigêmino- facial e índices cefalométricos de 30 voluntários, 10 da raça branca, 10 da raça negra e 10 da amarela, sexo masculino, 15 a 59 anos de idade, 1,60 a 1,80 m de altura e 60 a 80 kg de peso. Os registros do reflexo trigêmino-facial após estímulo elétrico unilateral do nervo supra-orbital pemiitiram análise quantitativa confiável de 3 respostas nos músculos orbicularis ocu/i: Precoce ipsolateral (RI), tardia ipsolateral (R2i) e tardia contralateral (R2c). Os índices cefalométricos foram obtidos multiplicando-se por 100 a razão entre o maior diâmetro transversal e o maior diâmetro sagital da cabeça:' As latências das respostas RI, R2i e R2c foram consistentes com os valores apresentados por outros autores, não havendo diferenças entre os grupos. As médias dos índices cefalométricos de cada grupo foram consistentes com as respectivas características raciais. Este estudo mostra que não há diferenças entre as latências de RI, R2i e R2c nas raças estudadasAbstract: The latencies of the blink reflex and the caphalometric indexes of 30 male volunteers were studied. Ten (10) were white, 10 were black and 10 were asian. The ages ranged from 15 to 59 years, the heights from 1,60 to 1,80 m, and the weight from 60 to 80 kg.The blink reflex records, after unilateral electric stimulation of the supraorbital nerve, allowed reliable quantitative analysis of 3 responses in the orbicu/aris ocu/i muscle: early ipsilateral (RI), late ipsilateral (R2i) and late contralateral (R2c). The cephalometric indexes were obtained multiplying by 100 the ratio between the longer head transversal diameter and the longer head sagital diameter. The latencies of the RI, R2i and R2c responses were consistent with other reports, and revealed no differences among the studied groups. The mean of the cephalometric indexes of each group were consistent with the respective racial characteristics. This study revealed that there are no differences among the RI, R2i and R2c latencies in the studied racesMestradoBiologia e Patologia Buco-DentalMestre em Ciência

Laryngeal Electromyography Techniques And Clinical Use

Laryngeal electromyography is considered a valuable diagnostic tool for voice disorders. The technique, described almost 70 years ago, evolved 3 decades later, mainly because of the growing interest of laryngologists and speech pathologists. In the authors' opinion, the reduced number of neurophysiologists involved in laryngeal electromyography groups is, at some instance, related to the difficulty to start the learning process and the multidisciplinary approach the field requires. This review highlights the anatomy and physiology needed to perform laryngeal electromyography and its clinical usefulness in the new field known as neurolaryngology.32427428

Blink reflex: comparison of latency measurements in different human races

Latências do reflexo trigêmino-facial e índices cefalométricos foram analisados em 30 voluntários adultos normais, de 3 diferentes raças, sendo 10 brancos, 10 negros e 10 orientais. Idades variaram de 15 a 59 anos, alturas de 1,6 a 1,8 m e pesos de 60 a 80 kg. Os reflexos trigêmino-faciais foram obtidos por estimulação elétrica unilateral do nervo supra-orbital e captação nos músculos orbicularis oculi, para análise quantitativa de 3 respostas, ipsolateral precoce (R1), ipsolateral tardia (R2i) e contralateral tardia (R2c). Índices cefalométricos foram obtidos multiplicando-se por 100 a razão entre maior diâmetro transverso e maior diâmetro sagital do crânio. As médias dos índices cefalométricos de cada grupo foram compatíveis com as respectivas características raciais. As respostas R1, R2i e R2c não mostraram diferenças de latências estatisticamente significativas entre as 3 diferentes raças analisadas neste estudo.The blink reflex latencies and cephalometric indexes were analysed in 30 male volunteers from three different races, 10 white, 10 black, and 10 Oriental. Ages ranged from 15 to 59 years, height from 1,60 to 1,80 m, and weight from 60 to 80 kg. Blink reflexes were obtained after unilateral electric stimulation of the supraorbital nerve for quantitative analysis of 3 responses, early ipsilateral (R1), late ipsilateral (R2i) and late contralateral (R2c), obtained from the orbicularis oculi muscle. Cephalometric indexes were calculated by multiplying the ratio between the longer transverse and the longer sagital head diameters by 100. The R1, R2i and R2c latencies were consistent with other published papers revealing no differences between the different racial groups. The mean of the cephalometric indexes of each group were consistent with respective racial characteristics. This study revealed that there are no differences between R1, R2i and R2c latencies in the 3 different studied races
