Mnemonics are extremely useful in learning the details of medicine, especially when there are "lists of key causes" to remember. These lists are often on written and clinical exams and medical board tests (such as National Boards and PANCE, Nursing Boards), so it is incumbent on the student to know them well. After a while, the use of mnemonics will become easy. This book contains over 200 "easy to recall" mnemonics and other pearls that will aid the student in grasping important lists of differential diagnoses concerning common medical problems. I have chosen the most common internal medicine problems in 13 main categories. -Robert M. Gullberg, MD, FACP
