Read full description

An engaging case-based approach to learning the diagnostic process in internal medicine Symptom to Diagnosis, Fourth Edition teaches an evidence-based, step-by-step process for evaluating, diagnosing, and treating patients based on their clinical complaints. By applying this process clinicians will be able to recognize specific diseases and prescribe the most effective therapy. Each chapter is built around a common patient complaint that illustrates essential concepts and provides insight into the process by which the differential diagnosis is identified. As the case progresses, clinical reasoning is explained in detail. The differential diagnosis for that particular case is summarized in tables that highlight the clinical clues and important tests for the leading diagnostic hypothesis and alternative diagnostic hypotheses. As the chapter progresses, the pertinent diseases are reviewed. Just as in real life, the case unfolds in a stepwise fashion as tests are performed and diagnoses are confirmed or refuted. Completely updated to reflect the latest research in clinical medicine, this fourth edition is enhanced by algorithms, summary tables, questions that direct evaluation, and an examination of recently developed diagnostic tools and guidelines. Clinical pearls are featured in every chapter. Coverage for each disease includes: Textbook Presentation, Disease Highlights, Evidence-Based Diagnosis, and Treatment. This app is very intuitive and easy to navigate, allowing you to browse the contents or search for topics. The powerful search tool gives you word suggestions that appear in the text as you type, so it is lightning fast and helps with spelling those long medical terms. The search tool also keeps a recent history of past search terms so you can go back to a previous search result very easily. You have the ability to create notes and bookmarks separately for text, images and tables to enhance your learning. You can also change the text size for easier reading. After the app has been downloaded, no internet connection is needed to retrieve the content of the app. All of the text and images are available to you on your device anytime, anywhere, and lightning fast. This app is also automatically optimized for whatever size device you are currently using, either phone or tablet.
