The World Health Organisation (WHO) Radiation Emergency Medical Preparedness (REMPAN) centres have built up the International Computer Database for Radiation Accident Case Histories (ICDREC) to document the treatment of acute radiation syndrome (ARS) patients. Radiation induced skin lesions may cause severe late effects in radiation accident patients. Dermatological multimedia documentation is included into the ICDREC. In particular, retrieval and display of digitised skin photographs and medical reports serves to improve patient care, medical education, and scientific analysis concerning the cutaneous radiation syndrome (CRS). The database has been built up as a client/server system. A particular focus has been set on using commercial off-the-shelf software components. The medical data including the multimedia data are stored in a relational database system. The database can be accessed by inexpensive personal computers in the dermatologist's workplace. Authorised institutions can access the database via the Internet. Retrieval of one skin photograph via local area network (LAN) requires approximately 3 seconds. The current state of the application is illustrated with the skin lesion treatment of a Chernobyl patient. An example is given on how to access the ICDREC from a dermatologist's desktop personal computer. The discussion focuses on the advantages of storing the textual and pictorial data in one central database to be accessed from different care centres and how the results can be generalised for medical multimedia information systems.
