김성한 교수의 Tough Cases in Infectious Diseases > 임상치과

For more than twenty years at the bedside, my research has begun where patient care leaves questions unanswered. Each case arrives with its own quiet provocations: Why did we miss the earliest moment to diagnose? Could a different pathway have led

to a safer, faster recovery? Over time, I came to see that research is not separate from the clinic—it is the disciplined pursuit of answers to the questions our patients give us.

This book grew out of fifteen-plus years of teaching residents and fellows how to turn those questions into studies worth doing—and papers worth writing. In morning reports, on rounds, and especially in our weekly Friday case conferences, we practiced

a simple habit: start from the case, ask many precise questions, then choose one that is answerable, impactful, and methodologically sound. Repeated often enough, that habit becomes a craft.

Part I is a practical invitation to that craft. It shows how a single case can branch into multiple researchable questions—diagnostic, therapeutic, prognostic, systemslevel—and how to narrow from curiosity to a study design that fits your time and data. The goal is motivation with traction: to help young physicians take a first step into research that improves care, not just careers.

Part II collects selected infectious-disease cases from more than fifteen years of those Friday conferences, refined into a quiz–answer–review format. The cases were chosen not for their drama but for their teachable pivots: a misweighted pretest probability, an overlooked exposure, a culture that finally clarified the picture, a treatment decision that proved decisive. Read them as you would see patients—one by one—and let each answer sharpen your clinical judgment and suggest your next study.
