The parotid glands and skin of the toad contain toxic substances. Ingestion of toad or toad cake may result in intoxication. Clinically, it may be predominantly manifested by a digitalis-like cardioactive effect. During the last six years, the National Poison Center of Taiwan has collected four cases of toad or toad cake intoxication: two cases were toad intoxication and two cases were toad cake intoxication. All four cases manifested with general weakness; three cases showed bradycardia, vomiting and diarrhea; two cases had numbness of the oral cavity; one case had excessive salivation; and two cases showed a consciousness change. In one case, an EKG showed bradycardia, and a first and second degree A-V block; this patient died of ventricular fibrillation. The prognosis in two cases was good. We lost contact with the last patient. The treatment principles in toad or toad cake intoxication is life support. If ingested, treatment is directed at prevention of absorption, including emesis, gastric lavage, activated charcoal and cathartics. Atropine, a pacemaker and other antiarrhythmic agents may be helpful in treating cardiovascular toxicity.
