The diagnosis of some kidney diseases in a small prolog Expert System

A medical expert system made in Visual Prolog 5.2 is proposed. This expert system makes a differential diagnosis among the main kidney diseases. The diagnosis is made taking into account the clinical exam (the symptoms that can be seen of felt) and the paraclinical exam (the results of laboratory tests). This system is designed to give help to a medical expert (doctor) in making the appropriate diagnosis of a patient. The kidney diseases have a lot of common symptoms and many of them are very much alike, and that makes it very difficult even for a kidney doctor (specialist) to put a right diagnosis. This Expert Sytem can do that. It contains knowledge about twenty-seven kidney diseases from nine different categories.
