The format of the book is excellent in that a formal presentation by an authority in the field is followed by a discussion among several experts, with the summary of the discussion at the end of the chapter. The book is divided into four parts. Part 1 is the discussion of the patient evaluation. Part 2, which represents the most important part of the publication, is entitled, "Nutritional Composition," and contains material on amino acid, carbohydrate, and fat solutions, in addition to information on vitamin and mineral preparations.
