Doctors can now tap a vast library of constantly updated medical knowledge merely by using a personal computer and a telephone, developers announced at the American Medical Assn. convention in Chicago. The system, called DXplain, contains data on more than 2,000 diseases, and will help physicians consider all possible diagnoses for a patient, spokesmen said. A doctor can subscribe to the service for a one-time fee of $30 to $50, depending on whether he is an AMA member, and use it for an average $5 to $10 per session.
