Question: What is (are) Stevens-Johnson syndrome ?
Answer: Stevens-Johnson Syndrome (SJS), also called erythema multiforme major, is a limited form of toxic epidermal necrolysis. This disorder affects the skin, mucous membranes and eyes. Stevens-Johnson syndrome occurs twice as often in men as women, and most cases appear in children and young adults under 30, although it can develop in people at any age. Having a gene called HLA-B 1502, increases risk of having Stevens-Johnson syndrome. It is an emergency medical condition that usually requires hospitalization. Treatment focuses on eliminating the underlying cause, controlling symptoms and minimizing complications and includes pain medication to reduce discomfort, medication to relieve itching (antihistamines), antibiotics to control infection, when needed and medication to reduce skin inflammation (topical steroids).
