I'm no longer posting literature updates to this blog. Old updates (March 2006 - April 2008) can be found here.
Instead, I'm writing for Faculty of 1000 Medicine, and I would recommend using their service to find articles of interest and reviews. In fact, you can visit this page to see the articles that I've recently evalutated for Faculty of 1000 Medicine.
Another useful updating service is provided for free by AMEDEO, which provides weekly updates of abstracts from the medical literature. Your updates are customized by topic and journals of interest. Check it out!
