Skin disorders are the most common adverse reactions attributed to drugs. Any skin disorder can be imitated, induced or aggravated by drugs. To help you keep up-to-date with the very latest skin reactions occurring with both new and established drugs, this section of the journal brings you information selected from the adverse drug reaction alerting service Reactions Weekly. The following case reports are selected from the very latest to be published in the world dermatology literature. Any claim of a first report has been verified by a search of AdisBase (a proprietary database of Adis International) and Medline. In addition, the World Health Organization (WHO) Adverse Drug Reactions database is also searched. This database, maintained by the Uppsala Monitoring Centre in Sweden, is the largest and most comprehensive adverse drug reaction source in the world, with information obtained from National Centers of 65 affiliate countries. Each case report is assessed for seriousness using the FDA MedWatch definition of serious (patient outcome is: death; life-threatening; hospitalization; disability; congenital anomaly; or requires intervention to prevent permanent impairment or damage).
