As physicians we collect clinical data through sight, sound, touch, and smell. Although physicians in the past used taste to collect data, such as tasting the sweet urine of a patient with diabetes, this sense is rarely, if ever, used in modern medicine. We listen to heart sounds, lung sounds, bruits, and percussion notes to collect information for diagnoses. We touch our patients to feel lumps, bumps, thrills, and masses. We occasionally use smell for diagnosis. Unfortunately, the smells of disease are rarely pleasant. Even the fruity odors of Pseudomonas are not like the sweet fruits of a farmers' market. Of course, we also use the patient's history, laboratory data, and more advanced imaging techniques to diagnose and manage patients' illnesses.
