Increasingly, medicine in general, and nephrology specifically, is based on clinical trials and verifiable presumption. Still, however, much of everyday clinical practice is the consensus of pundits and experts unable to validate their suggestions beyond personal bias. In this volume, several core beliefs in renal medicine are examined and challenged. Starting as assignments for nephrology fellows, this book grew out of surprising "revelations" indicating that "the emperor has no clothes". The book should be suitable as a stimulus for discussions for nephrologists, internists, house staff, and medical students.
