title: Dysphonia, an uncommon symptom of systemic neurotoxic envenomation by Vipera aspis bite. Report of two cases.
abstract: Two cases of Vipera aspis bites with severe envenomation in which, among other neurotoxic signs, dysphonia was observed, with alteration of the pitch of the voice are described. This uncommon symptom has never been reported in envenomation by European adders. It is pointed out that bites of European vipers should never be underestimated as severe envenomation may develop.
