Diagnosis - Symptom selection
Choose all clear-cut signs, symptoms and laboratory test results that you feel are related to the disease in question. The diagnostic specificity of this program increases with each additional entry. The absence of a certain finding is often as helpful as its presence.
- A
(left
click) displays a positive indication. - A
(right click) displays
a negative indication. - Note that
appears when a sign or symptom is incompatible with one of those marked.
Some of the signs and symptoms have a
to
the left of the finding. When you click on it, that symptom or sign list expands,
displaying more exact possible findings. For example, the heading "Dermatological
- Skin and Soft
Tissue" is followed by a listing of possible skin lesions.
In some cases, you may wish to generate a list of all diseases associated with a single finding or small group of findings (e.g., all of the diseases characterized by splenomegaly and eosinophilia). Such lists are often useful as teaching tools, but have limited value in diagnosing a specific patient.
Note: A built in safety mechanism ( fills the check box) prevents the
entry of mutually-exclusive parameters (e.g., both vaginitis and orchitis) for
the same patient. In some cases, seemingly contradictory findings (e.g., both
neutropenia and neutrophilia) are permitted, since they may appear at different
times during a given disease episode.
