Annals of Medicine and Healthcare Research is the proceedings of the second International Online Medical Conference, which was successfully held in March 2009. This two day event brought together professors, researchers, experts, and academicians from across the world and provided them with the opportunity to discuss their research findings in the field of medicine. The conference papers have been received from all around the world and have been peer reviewed and judged by experts before being accepted for publication. The IOMC organizes an annual online conference (http://www.iomcworld.com/) where participants present their papers and research using web conferencing. This book will provide a complete and useful resource of the latest research findings and discussions in the field of medicine which have been introduced and investigated in the IOMC Conference.
