In par- ticular, we have brought in our colleague, Dr Bockenhauer. We have used his expertise to ensure that this second edition is fully up-to-date in genetics. In addition, he has developed and simplifi ed the concepts of electrolyte balance by going back to basic renal physiology. Our original aim in producing a handbook that is a comprehensive and clinically-orientated guide to the management of children with all forms of renal disease remains. We have continued to try to make the text as practical as possible in the expectation that this will become the fi rst text that the paediatrician refers to when presented with a child with an acute or chronic kidney disorder. The book provides up-to-date information for the general paediatrician and the paediatric nephrologist. It is pocket sized so that it is easily referred to in the clinical setting and uses a system of bullet points to facilitate this. It covers both common conditions seen by all paediatricians during the day-to-day care of patients on a general paediatric ward or in the outpatient clinic, and also those seen rarely and usually in specialized paediatric nephrology centres in collaboration with local units. The focus is heavily on investigation and management and there is intentionally little emphasis on basic pathogenesis and disease mechanisms. Where possible we have made evidence-based recommendations, though in the many instances where high quality evidence is lacking, we make recommendations based on the authors’ personal experience and current best practice. All of the chapters have been written by the four authors, who are experienced consultants at two large UK Children’s Hospitals, although we have received signifi cant input from a number of our colleagues (listed on pages vi and vii) to whom we are most grateful. We would also like to thank Helen Liepman at Oxford University Press for seeing the handbook through from conception to delivery.
