RESUMO

In this study, developmental changes of N400 elicited by a simple paradigm to semantic incongruity were examined. Subjects were divided in three different age groups and education levels: Group I (first grade) = 7-8 years, n=10; Group II (third grade) = 9-10 years, n=10; and Group III (sith grade)= 11-12 years, n=10. EEG activity was recorded from 8 monopolar sites referred to linked earlobes. Data showed that the amplitude of the N400 like component did not change significantly from first to sith grade, although the onset latency appeared to be shorter in older children. No significant latency and amplitude changes were found among groups

RESUMO

Reports on simultaneous central and peripheral nervous system involvement in a patient with brucellosis are very rare. We report of one young female patient with a long history of consumption of non-pasteurized dairy products in which clinical and laboratory findings confirmed the existence of an active brucellosis with nervous system impairment. Cerebrospinal fluid were negative. Elctrophysiology and positive findings on sural nerve biopsy complemented the diagnosis of polyneuroradiculomyelo encephalitis. Treatment with a combination of doxycycline and rifampin for 2 months was successfully applied. No relapse or sequelae occurred in the patient after 12 monts of follow up
