This manual was written for oral board candidates, practicing physicians, residents, interns and medical students. It is meant to compliment standard texts and oral board courses (“practice makes perfect”). Also, it is designed to refresh and reinforce the “trouble-shooting neuronal synapses” (prn) of the emergency room physician, and as a brief reference in the ER (I find it particularly useful for “warming up,” just prior to returning to work following a vacation). I have attempted with this 1998 edition to at least “touch on everything,” and have purposely double spaced the text throughout, so that you can make your own strategically placed notes (pencil recommended)
