Medical Eponyms
Lindsay nails (1967)

Half-and-half nails is an apparent leukonychia of the proximal portion of the nail which is white and distinct from the reddish brown distal band, which occupies the remaining 20-60% of the nail bed.

Lindsay reviewed 1,500 patients on the general medical wards/ clinics of Iowa Hospitals were examined for nail abnormalities during the period of July 1964 to January 1966.

A new nail syndrome, designated the half-and-half nail, has been observed in 25 patients. Twenty-four of these patients had evidence of renal disease and 21 had azotemia. The pattern of proximal nail bed whiteness and distal nail bed red, pink, or brown band occupying 20% to 60% of nail length should alert one to the possibility of azotemia. This pattern seems distinct from that white nail of cirrhosis described by Terry.

Lindsay described how there was no correlation between the severity of azotemia and distal band length, and no pattern for sex, age or cause of renal failure found.
