Hickam's Dictum Essential facts:
- "Patients can have as many diseases as they well please".
- The principle is attributed to John Hickam, MD. (faculty member at Duke University in the 1950s).
- The actual process undertaken when diagnosing a patient is a continuous generation of hypothesis and then testing of that hypothesis, followed by then modifying the hypothesis, and so on.
- The principle of Hickam's dictum considers that a particular diagnosis should not be excluded solely because it doesn't appear to fit the principle of Occam's razor.
- It is frequently statistically more likely that a patient has several common diseases, rather than a single rarer unifying disease.
- Thus Hickam's dictum is useful in providing physicians with a counterbalancing principle to the uncritical use of Occam's razor in diagnosis.
- Saint's triad is the common combination of hiatus hernia, gallbladder disease, and diverticulosis (ascribed to C. F. M. Saint, British surgeon).
- The triad components have no known pathophysiological interrelationship - and thus the triad is counter to the usefulness Occam's razor.
