“…Sherlock (1959), nine years later in London, found that of 27 cases, four were Welsh, two Scottish and one Irish, ie, over 25 % were of Celtic origin. Most published series, eg, that of Foulk, Baggenstoss, and Butt (1959), mention a predilection of the disease for those of European descent, although cases in negroes are described (Ahrens, Payne, Kunkel, Eisenmenger, and Blondheim, 1950;Spellberg and Gattas, 1955) in the American literature.…”
