Book excerpt: Dr. Anthony Kalloo and Dr. Jonathan M. Buscaglia have taken years of experience at Johns Hopkins Hospital and created a collection of unique and interesting cases revolving around gastrointestinal and liver diseases. Complicated Cases in GI follows patient-physician interactions and includes over 50 cases that are complex in their nature, interesting in their presentations, or a representation of a unique therapeutic challenge. Each chapter case includes: - A detailed summary of a particular patient presentation - Associated pathology slides, radiology films, or endoscopy photographs - A brief evidence-based discussion focusing on the main learning objectives - Three to five key learning points listed to highlight the most important features Complicated Cases in GI also includes 150 board review-like questions taken directly from the cases themselves. The questions highlight the salient aspects and are meant to reinforce the learning objectives involved in each case. They will also serve as a useful study aid for anyone preparing for an examination in general medicine, gastroenterology or hepatology. Complicated Cases in GI is ideal for residents, fellows, practicing physicians preparing for recertification, nurses, and students looking for a quick reference text that can be read and absorbed over time--one case at a time.
