Due largely to the explosion of information related to molecular medicine, the introduction of new courses and concepts behind professional skill, medical ethics and mechanism of actions of new drugs, the medical curriculum has now become more crowded than ever. This is complicated by the fact that the time to study medicine has become compressed over the past two decades. Thus, if we have to bring 21st century curriculum to the medical students we must be innovative in terms of our approach to design a very compact curriculum in the presence of decreased contact hours to fulfil the need of more integration. The present book highlights the evolution of the medical curriculum and describes a state-of the-art approach that indicates the essential points behind designing a curricular map. Care has been taken to bring a concept that no particular curriculum may fit to the need of a medical school and thus it is necessary to fine tune a system that is ever rolling and dynamic in the context of medical education. The book not only addresses issues behind designing a curriculum for 21st century medical students but emphasises key issues such as integration, evaluation and assessment, students' feedback and 21st century modalities necessary for clinical and laboratory skill. The book is the first of its kind to address "Health and Disease" through understanding of the medical curriculum and should be very valuable to all medical educationists.
