Hey Dwayne,
I'm not quite sure what I'm looking for, and I think thats one of the problems.
The assignment is basically "Define and discuss these two aspects of diagnosis: Differential Diagnosis and Provisional Diagnosis" (1500 words) then it goes on to compare the DDx of a CP case and a shock case.
There is a plenty information around DDx lists for specific diseases, but I can not find much about DDx and the provisional diagnosis in itself.
The wiki stuff (and the about.com and answers.com) is good but unfortunately I can't use it as reference material
Cheers
