title: Toxic epidermal necrolysis - management issues and treatment options.
abstract: Toxic epidermal necrolysis (TEN) and Steven-Johnson syndrome (SJS) are characterized by extensive necrosis and cleavage of the epidermis from the dermis akin to a superficial or partial thickness burn. Sepsis is the usual cause of mortality but much of the pathophysiologic process results from an outpouring of cytokines and matrixmetalloproteinases (MMPs) which have a destructive effect on the extracellular matrix and may play a part in the epidermal/dermal cleavage seen with this disease. Recent attention has been focused on the modulation of proteases in an attempt to decrease the MMP-mediated destruction. Nanocrystalline silver (NCS) is one such agent that has good anti-microbial efficacy, but is also effective in modulating MMP levels. Twelve cases of confirmed TEN that were treated with NCS were analyzed with a view to assessing efficacy and setting logical guidelines for managing this condition, particularly in relation to immunosupressed patients. From this study important issues have been highlighted for discussion.
