This article has been retracted at the request of the Editor in Chief because of the stated concerns listed below. This article was accepted for publication by a previous editor and editorial board, at a time when submissions and documentation were in paper form, prior to the transition of The American Journal of Medicine to a digital submission and review process. ⋯ We have attempted to contact the authors regarding these concerns and received no response. We are therefore retracting this article since the evidence presented below strongly argues for scientific misconduct.
