The DERMatology INFOrmation NETwork (DERM/INFONET) of the American Academy of Dermatology has become a reality. DERM/INFONET consists of a number of data bases providing information and educational programs for the dermatologist. Currently the components are: DERM/MLS (Medical Literature Search), DERM/RX (dermatologic therapy), DERM/USP (United States Pharmacopeia data base), DERM/ALLERGENS (Food and Drug Administration and Environmental Protection Agency Listings of allergens); Melanoma Prognosis Model; Electronic Mail; Bulletin Board; Meetings Calendar; ICD/CPT (International Classification of Diseases/Current Procedural Terminology) codes; AAD Membership/Committee Directories; and Dermatology Quiz. Additional data bases are planned. As audiovisual and alphanumeric communication systems evolve, newer opportunities for enhancing the DERM/INFONET Biomedical Communication Network will undoubtedly provide even greater opportunities for aiding the dermatologist in delivering state-of-the art management for their patients.
