Colleagues, real and virtual, present and future. In the holidays, offering fun!!! To arrange a challenge game to interesting cases from pubmeda, NEJM. Collect case studies from NEJM, the answers are direct links (I hope the copyright is not broken, because I really want beautiful, beautiful discussion and with beautiful pictures:) the Winner, who guessed right more all cases, will give the e-book, purchased personally by me:
