—Dr. Ole Wasz-Höckert and Dr. Olof Widholm reported on tests they carried out to ascertain the behavior of the antistreptolysin titer in the various patients of the University Children's Hospital in Helsingfors (Nord. med. [Dec. 3] 1953, p. 1665). Hitherto most such investigations have dealt with adults or children of school age, but this investigation is concerned with 500 children treated in this hospital in 1949 and 1950. In 409 cases, the children had a variety of morbid conditions such as bronchitis and rheumatic fever; the other 91, who had slight psychic disturbances or conditions requiring surgical treatment and not representing any infection, served as controls. The streptolysin titer was examined at the University Sero-Bacteriological Institute in Helsingfors, and a titer greater than 1:200 was regarded as abnormally high. In more than half the patients with throat infections, the titer was abnormally high, in several cases over 1:600.
