The recognition of hemoagglutination in the presence of influenza viruses has greatly simplified virology. Since Hirst's (1941) observation, several other agents such as the viruses of vaccinia (Clark and Nagler, 1943) and mumps (Levens and Enders, 1945) and a pleuropneumonialike organism (Van Herick and Eaton, 1945) have been found to produce this as yet unexplained phenomenon. These reactions...

to streptomycin, it is not entirely clear how far this risk extends to the foetus. Certainly streptomycin does cross the placenta: this was established in 1945 by Woltz and Wiley and independently by Heilman et al. (1945). Subsequent work (Bernhard et al., 1950 ; Riskxer et al., 1952 ; Charles, 1954) confirmed that, although the effectiveness of the placental barrier varies, streptomycin and di...

Recent studies (Traub, Newhall, and Fuller, 1944, 1945; Seastone, 1947; Gump, 1945) on the compound hexachlorophene (G-11) (2,2'dihydroxy 3,5,6,3',5',6'hexachloro-diphenyl-methane)I have indicated a prolonged bacteriostatic effect on human skin. In order to explain this protracted effect, studies were conducted to determine whether hexachlorophene could be recovered from skin for several days f...

Gross and Hufnagel (1945) and Crafoord and Nylin (1945) independently reported successful repair of the coarctation of aorta. Since then many thousand patients have had surgical correction of this anomaly (Bailey, 1957; Campbell and Baylis, 1956; Cleland et al., 1956; Keith, Rowe, and Vlad, 1958). There have been numerous reports dealing with the immediate post-operative period (d'Abreau and Pa...
