Polyneuropathy Following Exposure To Insecticides

Abstract
A cause-and-effect relation between exposure to insecticides and subsequent development of polyneuropathy is very difficult to prove even when strongly suspected. However, in the two cases described below such a relation is so probable that we believe their full report is warranted. Our two patients had albuminocytologic dissociation in the spinal fluid and might have been considered to be suffering from a sporadic form of the Guillain-Barré syndrome (acute idiopathic polyneuritis) of cryptogenic origin had not the close association between exposure to insecticide and neurologic manifestations made an etiologic relationship probable. Despite the enormous quantities of insecticides used annually, case reports of polyneuropathy caused by them are few, perhaps because of their rarity, but perhaps also because of failure of physicians to consider insecticides as a possible causative agent. Case 1 —A 13-year-old boy was admitted to the North Carolina Baptist Hospital for evaluation of weakness and paresthesias. He was
