Instructions from the editor:
Diagnosaurus provides differential diagnoses (DDx) of symptoms, signs, and diseases. By using the various indexes, you can choose to view entries by organ system, or select to view the list of symptoms only, the list of diseases only, or all of the entries. For example, if you wish to review the causes of a patient's chief complaint, simply select the symptom or sign from the alphabetical listing. If you have made a diagnosis and wonder what other disorders to consider, select your diagnosis from the list to see its DDx.
