| '''Stevens-Johnson syndrome''' (SJS) is a life-threatening [[condition]] affecting the [[skin]], in which due to [[cell death]] the [[epidermis]] separates from the [[dermis]]. The syndrome is thought to be a [[hypersensitivity]] complex affecting the skin and the [[mucous membrane]]s. Although the majority of cases are [[idiopathic]], the main class of known causes is medications, followed by infections and (rarely) cancers.

| ==Classification==
| |
| There is agreement in the medical literature that [[Stevens-Johnson syndrome]] can be considered a milder form of [[toxic epidermal necrolysis]] (TEN). However, there is debate whether it falls on a spectrum of disease that includes [[erythema multiforme]] and '''erythema multiforme major''' (also known as '''erythema multiforme majus''').<ref>{{cite journal |author=Carrozzo M, Togliatto M, Gandolfo S |title=[Erythema multiforme.

| SJS can be caused by infections (usually following viral infections such as [[herpes simplex virus]], [[influenza]], [[mumps]], [[cat-scratch fever]], [[histoplasmosis]], [[Epstein-Barr virus]], or similar), allergic reactions to drugs, (Dicloflex, [[fluconazole]],<ref name="NZ">[http://www.medsafe.govt.nz/profs/Datasheet/d/DiflucanOnecap.htm Medsafe Data Sheet] March 8, 2005.

| Although Stevens Johnson Syndrome may be caused by viral infections or malignancies, severe allergic reactions to medication is the leading cause. Medications that have traditionally been known to lead to Stevens Johnson Syndrome, [[Erythema multiforme]], and [[Lyell's Syndrome]] ([[Toxic Epidermal Necrolysis]]) include;

| *[[penicillin]]'s (antibiotics)

| ==Treatment== | | ==[[Stevens-Johnson syndrome causes|Causes]]== |
| Discontinue all medications, particularly those known to cause SJS reactions. Treatment is initially similar to that of patients with thermal burns, and continued care can only be supportive (e.g. IV fluids) and symptomatic (e.g. analgesic mouth rinse for mouth ulcer); there is no specific drug treatment (2002). Treatment with corticosteroids is controversial since it might aggravate the condition or increase risk of secondary infections. Other agents have been used, including [[cyclophosphamide]] and [[cyclosporine]], but none have exhibited much therapeutic success. Intravenous immunoglobulin (IVIG) treatment has shown some promise in reducing the length of the reaction and improving symptoms. Other common supportive measures include the use of topical pain anesthetics and antiseptics, maintaining a warm environment, and intravenous analgesics. An [[ophthalmologist]] should be consulted immediately, as SJS frequently causes the formation of scar tissue inside the eyelids leading to corneal vascularization and impaired vision, as well as a host of other ocular problems. Also, an extensive physical therapy program ensues after the patient is discharged from the hospital.

| ==Prognosis== | | ==[[Stevens-Johnson syndrome differential diagnosis|Differentiating Stevens-Johnson Syndrome from other Diseases]]== |
| SJS proper (with less than 10% of body surface area involved) has the [[mortality rate]] of around 5%. The risk for death can be estimated using the '''SCORTEN scale''', which takes a number of prognostic indicators into account.<!--
