Preface Déjà Review™ USMLE Step 2 CK has been scrutinized and edited to produce a second edition that is even higher yield and easier to use than the first Outstanding medical students, who have recently taken Step 2, revised the original text to ensure the material covered herein is complete and current The authors, now with a combined 30 years of experience in the medical field, have also edited the manuscript to emphasize the clinical relevance of the core concepts covered in Step 2 We are confident that our efforts have produced one of the most useful guides for Step 2 review available today Step 2 of the United States Medical Licensing Examination (USMLE) tests the senior medical student’s ability to apply the basic principles of clinical medicine However, before you can apply those principles, you must be able to rapidly recall a core body of essential facts This is why the Déjà Review series is the most efficient, well-organized, portable, and above all, high-yield resource to prepare students for the USMLE As recent graduates who have taken Step 2, we are confident that we have compiled a novel review guide that promotes rapid recall of all of the essential facts necessary for success on this examination We also realize that a solid foundation in these principles will allow you to make a smooth transition into your residency ORGANIZATION All concepts are presented in a question and answer format that covers the key facts on hundreds of common and uncommon diseases The material is divided into chapters covering the six major divisions of clinical medicine: internal medicine, surgery, neuroscience, psychiatry, OB/GYN, and pediatrics We have also included a brief emergency medicine chapter that addresses topics not covered under emergent conditions in each of the other chapters This question and answer format has several important advantages: • It provides a rapid, straightforward way for you to assess your strengths and weaknesses • It allows you to efficiently review and commit to memory a large body of information • It will prepare you for getting “pimped” by residents and attendings on the wards • It offers you a break from tedious, convoluted multiple-choice questions • The clinical vignettes will expose you to the prototypic presentation of diseases classically tested on the USMLE Step 2 • It serves as a quick, last-minute review of high-yield facts The compact, condensed design of the book is conducive to studying on the go, especially during any downtime on the wards HOW TO USE THIS BOOK Remember, this text is not intended to replace textbooks, course packs, or lectures It is, however, intended to serve as a supplement to your studies during the third and fourth years of medical school This text has been sampled and refined by a number of medical students who found it to be an essential part of their preparation for the USMLE shelf examinations, in addition to Step 2 itself We recommend having the text spiral bound to make it more portable and easier to use Begin using this book early in your third year by carrying it with you during your clinical clerkships You may cover up the Open angle
