German anaesthesiologist Joachim Boldt was fired last autumn from his job as head of anesthesia at the Klinikum Ludwigshafen after concerns about a 2009 paper surfaced - namely that the study was completely made up.   Boldt has published numerous articles about the safety of a type of surgical fluid replacement called hydroxyethyl starch and now concerns about his research may may mean up to 90 retractions.
