A computer based handbook and atlas of pathology.

The Diagnostic Encyclopaedia Workstation (DEW) is a computerized handbook of pathology intended for use in diagnostic practice. It consists of a combination of a personal computer (PC), a video disc player (VDP), for which a specially developed disc is used, two monitors, a mouse and software. The hard disc of the computer contains textual information on diagnoses in categories such as macroscopy, common histology, immunopathology, clinical observations and prognosis and case histories. This information is frequently illustrated by pictures on a video disc which is automatically addressed by the computer software. All pictures, at present some 3000, pertain to case histories which are included in the system. Also integrated are classification aids in two categories: diagnostic criteria and differential diagnosis. Advantages of DEW over the use of conventional manuals are 1) the extensive volume of text, 2) the large number of high quality illustrations, 3) the immediate access to cross references and 4) the potential for continuous revision.
