With the increasing incidence of Type 2 diabetes in the adult population and the realization that this is a vascular disease and a major coronary risk factor, Professor Betteridge has chosen fifty diabetologists to contribute a case which has had an effect on their clinical practice. Both Types 1 and 2 diabetes are included, along with other forms of diabetes, eg gestational. Each case is presented in the same format. The various cases are informative and educational and should provide the reader with a sounder knowledge of patient and disease types.
