Professors David Little (Sydney, Australia) and Charles Mehlman (Cincinnati, Ohio, USA) attended our grand rounds on 18 June 2013 held at St Barholomew's Hospital. The varied and fantastic program is attached below. A great educational day was organised followed by a fun dinner where more ideas were exchanged. Here are Professors Little (first from left) and Mehlman (second from right) with Manoj Ramachandran (second from left) and Arun Ranganathan (first from right).
