PREFACE
edical advances have been occurring at breathtaking speed, with diagnostic and treatment
options becoming available for conditions for which none previously existed. However, several
aspects of health care remain the same. Patients continue to rely heavily on clinicians for help in
understanding the burgeoning evidence in medical research and for providing optimal health
care. Clinicians remain steadfast in their quest to meet the needs of their patients and to encourage
innovation in meeting those needs. The focus on patient safety and quality of care remains a key-
stone of medical practice, and multidisciplinary care with a system-based approach is increas-
ingly being adopted to manage chronic disorders. The associated demands and challenges mandate
that physicians remain abreast of the latest developments in medicine. To assist physicians in this
endeavor, the Department of Internal Medicine at Mayo Clinic provides continuing medical
education updates and resources in a timely manner. This book, Mayo Clinic Internal Medicine
Review, is designed to meet the needs of practicing clinicians and physicians-in-training by updating
their knowledge of internal medicine and helping to prepare them for the internal medicine cer-
tification and maintenance of certification examinations administered by the American Board
of Internal Medicine (ABIM).
The success of the earlier editions of this textbook is exemplified by the number of books pub-
lished. The positive reaction to and the success enjoyed by the earlier editions prompted the
Department of Internal Medicine to proceed with the publication of the eighth edition. Each
chapter has been thoroughly updated, and a new chapter on hospital medicine has been added.
The goal is to provide an update in internal medicine that is readable and easy to study.
This book is divided into chapters based on subspecialty topics and written by authors with
expertise in the respective fields of medicine. Bulleted items highlight elements that are impor-
tant concepts. The repetition of important points in the chapters reinforces the essential aspects
of the topics and serves as an additional aid in review of the subjects. Multiple-choice ques-
tions appear at the end of each chapter; there are more than 350 multiple-choice questions in
this edition. Correct answers and detailed explanations follow the questions.
I am grateful to all the individuals who contributed ideas and suggestions for improvement
during the development of this book. I thank the esteemed authors of the previous editions for
their input into this edition and for permitting the use of some of the materials from previous
editions. I am indebted to all authors for their immense effort and contributions to this edi-
tion. I thank the staffs of the Section of Scientific Publications, Department of Medicine, and
Division of Media Support Services at Mayo Clinic for their contributions to this edition. The
support and cooperation of the publisher, Informa Healthcare, are also gratefully acknowledged.
I trust that the eighth edition of Mayo Clinic Internal Medicine Review will continue to update
and advance the reader’s knowledge of internal medicine.

FOREWORD
he eighth edition of Mayo Clinic Internal Medicine Review is a reflection of the continued com-
mitment by the faculty of the Department of Internal Medicine to its mission to “serve the patient
and advance the science.” There are substantial differences from the previous edition as a result
of extensive revisions. All chapters were updated, 12 new authors and 2 new associate editors
were recruited, a new chapter on hospital medicine was added, and new tables, figures, and ques-
tions and answers were included. These changes and improvements are consistent with the theme
eloquently articulated by William J. Mayo, MD, in 1928: “The glory of medicine is that it is
constantly moving forward, that there is always more to learn.”
*
My hope is that the reader will
find the contents of this book informative, enjoyable, and, most of all, useful in our shared objective
of understanding, preventing, diagnosing, and treating the diseases that still plague the human race.

PREFACE TO THE FIRST EDITION
or more than 2 decades, the staff of the Mayo Clinic and faculty of the Mayo Graduate School
of Medicine have provided in-house didactic presentations for residents and fellows preparing
for the internal medicine certifying examination administered by the American Board of Internal
Medicine (ABIM). The extreme popularity of the Mayo “board reviews” among the residents
and fellows and other physicians prompted the initiation of “Mayo Internal Medicine Board
Review” courses in August 1992 to all physicians. Nearly 200 physicians in 1992 and twice that
number in August 1993 attended the courses offered in Rochester, Minnesota. The popularity
and the great demand for the course syllabus inspired us to write this book for candidates preparing
for the ABIM examinations in internal medicine. This book, Mayo Internal Medicine Board
Review 1994-95, will be used as the course syllabus for the “Mayo Internal Medicine Board
Review” courses to be held in 1994 (July 24-30) and 1995 (July 23-29) in Rochester, Minnesota.
This is not a comprehensive textbook of medicine. It is rather analogous to a guide or a note-
book containing selected topics deemed important for candidates preparing for the certifying or
recertifying examinations offered by the ABIM in 1994 and 1995. The authors of this book
assume that the candidates preparing for the board examinations will have studied at length a
standard textbook of medicine before reading this review. The chapters are divided by subspecialty
topics. As a means of underscoring the important clinical points for the boards, many paragraphs
are followed by selected “pearls.” Some of these pearls may seem repetitious, but this approach
is intentional. We hope this format will aid readers in recapitulating the salient points of the topic
under discussion. The questions at the end of each chapter are intended to familiarize the can-
didates with the format of the ABIM examination. Answers to these questions and their expla-
nations are at the end of the book.
My coauthors and I are truly pleased to present this book and anticipate that it will be valuable
to anyone preparing for the certifying and recertifying examinations in internal medicine of the
ABIM. We look forward to hearing comments and suggestions from readers.
