What is sometimes the only physical manifestation of bulimia nervosa? These so-called "old fashioned" historical clues and physical signs are not only part of our medical heritage; their deployment can often spell the difference between prompt clinical diagnosis versus a costly investigative odyssey. Often overlooked with today's emphasis on laboratory testing, a diagnostic pearl such as knowing that a diabetic patient with peripheral neuropathy may actually have metformin-induced vitamin B12 deficiency can be a shortcut to disease recognition.
