Cystic fibrosis used to be thought of as a respiratory and digestive disease, with a uniformly and rapidly fatal outcome. The spectrum of the disease has broadened into the mild atypical case, presenting in middle age, with the potential for complications in virtually every system of the body. In the past few years there has been an explosion of knowledge of the basic science of the defect. Although there are many "Recent Advances" texts, previous books have been selective in their choice of topics. This book is the first to cover the entire field of this complex disease, and encompasses the rapidly moving topics of the basic molecular and cellular biology as well as the recent multi-system, multi-disciplinary advances in the clinical care of patients. The authors have been charged with writing only about new developments and not to rehash old literature. The bulk of the references is therefore less than five years old.
