The course I am is becoming more and more clinical (very rapidly in fact), so whereas learning before was just a case of learning lecture slides (give or take some extra reading) things have changed.
Now its more a case if you see a patient with a certain disease, you just go away and read about it in a book. Because of this I have obtained a copy of Kumar and Clarkes clinical medicine. It feels liberating to read a textbook aimed for clinical medicine as opposed to a book relating to physiology or pharmacology.
However the best book I have purchased in the Oxford Clinical Handbook of Medicine - perfect for taking a sneaky look as the consultant chooses who to pick on.
