urements were determined in children. Compari-
sons 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%. Ofthe 18
children not seen in 1958 but examinedin 1959,
14 were babies bornin the interval between the
two examinations.
The age distribution of children examined in
1959 wasas follows:

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 many of these
conditions could have been related to the ages of

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 incidencein relation to varlous exposure categories was as follows:

(Tables 7 and 8). The ages were based on the best
available birth date estimations. A tendencyfor
these findings to occur more frequently in the
youngerchildren was noted. Theincidences, however, did not appearto be related to exposure to
radiation.
During the physical examinations, the following
congenital anomalies were recorded:

Hypoplasia of the middle phalanx has been reported 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 wascarried out preceding and following the regular examinations. In
all, 36 children were treated. The presenting complaints are shown in Table 9.
