“…Diamond and Blackfan (1938) gave a more detailed description of the disorder in four children, and emphasized the features of a chronic progressive anaemia beginning early in infancy, with a tendency to moderate depression of the leucocyte and thrombocyte counts, and selective hypoplasia of the red cell precursors in the bone marrow. Several reports of this disease have appeared since (Rinvik, 1940;Kohlbry, 1941;H0yer, 1942;Rubell, 1942;Robson and Sweeney, 1948;Smith, 1949Smith, , 1953Smith, , 1959Palmen and Vahlquist, 1950;Cathie, 1950; Lelong, Joseph, Polonow-ski, Desmonts and Colin, 1951; Anderson, 1952;Donnelly, 1953;Aldridge and Kidd, 1953; Kass and Sundal, 1953;Verger and Leger, 1953;Fisher and Allen, 1953; Arrowsmith, Burris and Segaloff, 1953;Burgert, Kennedy and Pease, 1954;Diamond, 1954;Harper and Geikie, 1955;Calvert and Robson, 1956;Sundal, 1956;Pearson and Cone, 1957;Gasser, 1957), and a total of about 70 cases have been recorded. The reports have conformed to the original descriptions, with the exception that marrow examinations in some instances have revealed normal or increased numbers of normoblasts (Cathie, 1950).…”
