cases with 7th nerve weakness involving the lids; two cases of anisocoria (unequal pupils); and an increased incidence of strabssmus. Residval “Bete Burns” Persisting residual effects of “beta burns” were found to be present in 19 people, 6 children and 13 aduits. These are outlined in Table 17. The skin changes consisted of hyperkeratosis, and varying degrees of atrophy, scarnng, and pigment aberrations (see Figures 19 and 20). These changes were slight in most of the people. The devclopment of lentigo-like and papular pigmented nevus-like jesions in arcas of previous ' beta burns” was first observed several ycars ago. and these lesions appear to have been increasing slightly unce that time (see Figure 21). Histological study of a biopsy of one of these lesions showed it to be a typical benign pigmented nevus. The residual changes in the skin of the Marshallese who had sustained acute “beta burns” have shown neither fissure tigsue breakdown in the affected areas as wen in chron radiation dermatitis nor evidence of malignant change. Only one case showed a few spewabalopecia of the occipital area of the scalp as a residuum ofepilation.
