Spider Bite: A Rare Case of Acute Necrotic Arachnidism with Rapid and Fatal Evolution

Case Reports in Emergency Medicine, Volume 2016, Issue 1, 2016., 2016
The spider bites are quite frequent and often resolve quickly without leaving outcomes; only some species are capable of causing necrotic and systematic lesions in humans. Among them, we should mention the genus Loxosceles. The venom released from the spider bite of Loxosceles species is composed of proteins, enzymes, and nonenzymatic polypeptides. The

Loxoscelism and negative pressure wound therapy (vacuum‐assisted closure): an experimental study

International Wound Journal, Volume 7, Issue 6, Page 488-492, December 2010., 2010
Brown recluse spider (Loxosceles) bites cause lesions ranging from chronic necrotic ulcers to acute life‐threatening sepsis. Based on our experience in treating acute and chronic wounds with negative pressure, we postulated that vacuum‐assisted closure (VAC) would be valuable in this application.
