Query: I feel duped!!!!!!!!!!

I would like to start by saying that the overall format of the book is great and could be useful but I would be ashamed to call myself an editor for this text and call it a "new" addition. The text is clearly out of date which is a shame because if someone would have had the energy to do it right this could have been a gem. I don't expect something published in 2005 to refer to cardiac troponins as a new test. There are abundant references to streptokinase which I guess is acceptable but most new grads finishing an er residency will have never heard of LDH1/LDH2 ratios and most certainly lovenox has become more commonly used in practice since this books last printing (the only form of heparin mentioned is IV). Give me a break! Don't re-publish old stuff and call it a new addition without updating it.
