frequently observed sequelae in survivors.21:T51d,• We looked retrospectively for all cases of toxic epidermal necrolysis that occurred in France over a 5-year period to appreciate the incidence of this disorder and its drug etiology. Of the 399 cases identified, we obtained detailed information on 344 cases and validated 253 cases. From response rates (66% to 98%), we estimated the actual total number of cases to be 333, and the incidence of toxic epidermal necrolysis in France to 1.2 cases per million per year. An independent estimation derived from death certificates gave a figure of 1.3 cases per million per year. When the number of cases with a given drug present were related to the defined daily doses of that drug sold over the 5-year period, the highest ratios were for sulfadiazin (230 · 10^-8), isoxicam (41 · 10^-8), oxyphenbutazone (18 · 10^-8), phenytoin (14 · 10^-8), fenbufen (13 · 10^-8), and cotrimoxazole (12 · 10^-8). This first nationwide study confirmed the rarity of toxic epidermal necrolysis. Within the two main classes of responsible drugs (antibacterial sulfonamides and nonsteroidal anti-inflammatory agents) the risks linked to different drugs appeared quite different, even for closely chemically related products. (Arch Dermatol.1990;126:37-42)22:T4e8,Fifteen consecutive patients with toxic epidermal necrolysis or the Stevens-Johnson syndrome managed without corticosteroids after transfer to the burn center (group 2) are compared to a previous consecutive group of 15 who received high doses of these drugs (group 1). Group 2 had a 66% survival, which was a significant improvement compared to the 33% survival in group 1 (p = 0.057). In group 1, mortality was associated with loss of more than 50% of the body surface area skin. In group 2, mortality was related to advanced age and associated diseases. Age, extent of skin loss, progression of skin loss after burn center admission, incidence of abnormal liver function tests, and the incidence of septic complications were not significantly different in the two groups (p greater than 0.10). The incidence of detected esophageal slough was similar in both groups. Nonsteroid (group 2) management was associated with a decreased incidence of ulceration of gastrointestinal columnar epithelium, Candida sepsis, and an increased survival after septic complications. The combined experience of these 30 patients suggests that corticosteroids are contraindicated in the burn center management of toxic epidermal necrolysis and the Stevens-Johnson syndrome.
