16 PHYSICAL EXAMINATIONS Adult Examinations The general health and nutritionalstatus of the people of Rongelap and Utirik Atolls weresatisfactory and about the samein the exposedasin the unexposed populations, with the exception of thyroid abnormalities in the exposed Rongelap population, which will be treated separately below because of the importance of this development. As noted in previous surveys, the variety and distri- bution of physical abnormalities (with the exception of thyroid nodules) did not appearto besignificantly different in the exposed and unexposed populations. The varying incidence from yearto year of such findingsas cervicitis, prostatic hypertrophy, and arteriosclerosis probably to some ex- tent reflects differences in clinical criteria ofjudgment among the examiners. There was a marked tendency for extensive dental caries in young adults. Special ophthalmological andslit-lamp observations for lens opacities were not carried out during the past 2 years. Physical abnormalities in the adults are listed in Table 10. Figure 7. Part of a physical examination.
