I'm looking for either a program (for pda) or website where you can plug in multiple symptoms a patient is complaining of and it will pop out a list of the most likely differentials. Very simily to how GeneClinics works, where you put in a list of all the abnormalities in a patient and it pops out likely Genetic conditions for you to persue. I have Diagnosaurus, but as far as I know, you only select one complaint to general the DDX. I would like to be able to cross check several if that's possible. Any suggestions?
