A patient with LEMS unrelated to cancer was studied by

CASE OF THE MONTH

stimulated single-fiber electromyography (SFEMG) before and 3 months after the onset of therapy with 3,4-diaminopyridine. All end-plates showed Section Editors a progressive reduction in blockings and jitter with the increase in stimulation rate. Treatment significantly corrected this feature, but the overall pattern of Robert C. Griggs, MD frequency-improved jitter remained. Such widespread finding is rare but Rochester, New York diagnostic for Lambert-Eaton myasthenic syndrome. Stimulated SFEMG

Diaminopyridine (3,4-DAP) is known to be beneficial in the symptomatic treatment of the Lambert-Eaton myasthenic syndrome (LEMS). The effects of 3,4-DAP on the decay of postexercise augmentation were observed in 6 patients with LEMS. After 10 s maximal voluntary contraction, the amplitude of the co
