Clinical and electrodiagnostic findings in cyhalothrine poisoning.
Acute onset bulbar symptoms with respiratory failure and descending paralysis may occur in several neuromuscular disorders including variants of Guillain-Barre syndrome (GBS), diphtheria, botulism and toxins. We present a 51-year-old man who presented with complains of ptosis and dyspnea following pyrethroids spraying in an enclosed area for eradication of flea. Within 5-6 days of admission limb weakness, dysphagia, dysarthria, blurred vision, diplopia, tremor and respiratory distress added to previous symptoms. Temporal profile of events after exposure, development of similar symptoms in patient's son, electrodiagnostic findings and exclusion of other etiologies confirms intoxication etiology. We reviewed the literature and provide an extensive electrodiagnostic overview.
