urements were determined in children. Compansons have been made between the numbers exam-
ined each year. Excluding those who wereshifted
into the adult study, the total over-all attrition
rate between 1958 and 1959 was 10%. Of the 18
children not seen in 1958 but examined in 1959,
14 were babies born in the interval between the
two examinations.

The occurrence of various medical conditionsis
summarized in Table 6. There seemed to be no
concentrationofclinical abnormalities in the exposed groups. Since the incidence of manyofthese
conditions could have been related to the ages of
the children at the time of examination,two of the

most frequent findings, active chronic impetigo
and palpableliver over 3 cm in size, were tabu-
lated separately for several different age groups
(Tables 7 and 8). The ages were based on the best
available birth date estimations. A tendency for
these findings to occur more frequently in the
younger children was noted. The incidences, however, did not appearto be related to exposureto
radiation.
During the physical examinations, the following
congenital anomalies were recorded:
Patent ductus arteriosus (repaired)
Deformityof the hip
Pectus excavatum
Bifid uvula

In addition, the incidence of congenital hypoplasia of the middle phalanx ofthe fifth finger was
determined from inspection of the roentgenograms
of the left hand. The incidence in relation to varlous exposure categories was as follows:

1959 wasas follows:
Hypoplasia of the middle phalanx has beenreported as occurring in the normal population in
incidences ranging from 0.5% to 5.2%. The anomaly was found to have considerably greater frequency (25%) in Japanese children.”* The over-all
incidence in the Marshallese children was 0.77%.
Pediatric dispensary work was carried out preceding and following the regular examinations. In
all, 36 children were treated. The presenting complaints are shown in Table 9.
