title: [Envenomation and poisoning by venomous or poisonous animals. VII: arachnidism in the New World].
abstract: The incidence of scorpion stings and spider bites is high in Latin America. This is particularly true for Mexico, part of Amazonia, and southern and eastern Brazil. Centruroides and Tityus scorpion stings present a real danger for humans, especially children. Envenomation results in intense pain, neurological signs, and cardiorespiratory manifestations that can lead to death by acute pulmonary edema or heart failure. In the event of confirmed envenomation, antivenin must be administered as soon as possible in association with symptomatic treatment and, if necessary, cardiorespiratory resuscitation. Spider bites are a less frequent and severe. Envenomation by Loxosceles is extremely painful and necrotizing. Severe visceral complications can develop. An effective antivenim has recently become available for local and systemic envenomation. Envenomation by Latrodectus leads to neurological symptoms that can also be treated with antivenom. Envenomation by other spiders is less frequent and generally harmless.
