earlier surveys, residual findings from a poliomyelitis epidemic were recorded
in a few individuals. The liver was palpable in a number of children, but the
frequency appeared to be related to young age and not to clinical histary or

other physical findings.
Complaints noted during dispensary visits followed a general pattern

modified primarily by the acuteness of the condition.
The most frequent reasons for emergency clinic visits were cough, fever, anorexia, otitis, skin
lesions, and diarrhea.
Most of the dispensary care involved infants and very

young children. Routine examinations of babies born after the return of the
Rongelap inhabitants revealed no obvious differences among those born to exposed parents compared with those born to unexposed parents.

The major findings to emerge from the pediatric studies were (1) develop-

ment of thyroid neoplasia, both benign and malignant, in the exposed children,
(2) growth retardation secondary to thyroid injury from radiation in some exposed children on Rongelap, and (3) acute myelogenous leukemia developing in

1972 in a boy exposed at age 1 year on Rongelap who also had a thyroid adenoma

resected in 1962.

These are discussed in more detail in other sections of

A continued high incidence of intestinal parasitism has beer noted.
This problem is discussed in Section VI, and recent efforts to treat parasitism on Rongelap and Utirik are described.
Variations in serum electrolytes and other chemistries occurred in ran-

dom fashion among all groups and were seldom persistent on repeat examination.
Statistical evaluations of routine laboratory screening test results, other
than hematological, have not been performed.
Table 3 presents a mortality list with possible causes of death.
The
latter were, in most instances, presumed, since death generally occurred

without a physician or health aide in direct attendance, and autopsies were
rarely performed because of strong Marshallese cultural resistance to such

procedures.

Records maintained by local health aides on the outer islands

were often marginal in content and accuracy, if not entirely missing, and
follow-up questions regarding potential causes of death were often met with
uninformative responses, such as death due to old age.
