"Just the Facts" by Ma is a condensed version of baby Tintinalli's and a quick but useful read. Basically a paragraph on epidemiology, pathophysiology, diagnosis, treatment/disposition. very nice and condensed with the high-points.
EMRA's Top 30 problems in EM also is a nice pocket guide that has evidenced based answers on how to work up the 30 most common problems encountered in the ED. I liked it for my rotations.
