The facts about cystic fibrosis (CF) are presented in 1 in 20: Cystic Fibrosis, which offers the information in a manner well-suited to both children and adults. CF is the most common life-endangering genetic disease in the U.S. and is passed on to children when both parents carry the CF gene. In this animated program, the narrator discusses the procedures that are part of a CF patient's routine, which include physiotherapy and medications to manage digestive enzymes and to fight possible infections. The lifespan of patients has been extended through better methods of treatment. ~ Alice Day, Rovi
