ABSTRACT

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

ABSTRACT

Neste trabalho os autores descrevem três casos de miopatia do multicore na mesma família. O caso 1 corresponde a um paciente de 77 anos, com fraqueza e atrofias proximais, hipotonia e hiporreflexia profunda globais. Estudos da cnduçäo nervosa sensitiva e motora foram normais nos quatro membros. A eletromiografia revelou padräo miopático, com atividade espontânea frequênte, tipo fibrilaçöes e ondas agudas positivas. As reaçöes histoquímicas mostraram alteraçöes oxidativas típicas de miopatia do multicore. Os casos 2 e 3 correspondem a filho e filha do paciente 1, respectivamente. Estes dois casos eram assintomáticos, mas apresentavam discretas alteraçöes eletromiográficas e à biópsia de músculo. Os três pacientes ilustram a grande variabilidade clínica desta entidade

ABSTRACT

Sinusites podem acometer tecidos adjacentes, dentre eles o sistema nervoso. Neste trabalho descrevemos um caso de sinusopatia maxilar ocasionando anormlidade pupilar rara com reaçäo paradoxal à luz. Que seja de nosso conhecimento é a primeira vez que esta associaçäo é descrita
