GC» Congenital anomalies.

The incidence of congenital anomalies

is believed to be higher than found in Americans.

The increase may be due

to the fact that these people have been tiving in a relatively isolated area
for some 2000 years with prevalent consanguinous matings.
d. Laboratory findings of interest.
EBosinophilia is prevalent.

As pointed out about half of the

people have greater than 5% eosinophiles in their differential counts.

An

intestinal parasite survey at the 4 year study revealed stools positive for
various parasites in about 80 to 85% of the people.

However, hookworm was

the only parasite noted which is generally associated with eosinophilis, but
the incidence was too low (about 2% of the people} to account for the gener- |
ally high eosinephile counts,

responsible.

Another possibility is that the incidence of trichinosis ine

festation may be high.

This will be a subject of further study.

The low incidence

of bookworm would not account for the low hematocrit readings.

In fact,

there was no correlation in individvuais between hematocrit, parasite infes=

tation or eosinophilia.

The tendency toward low hematocrits may be related

to nutritional deficiency of iron or proteins but there is no good evidence

that these factors are involved.
These people generally show hich total serum protein levels (mean

of 8 g) with increased gamma globulin (mean of 2.4 g).

The explanation for

these findings is not immediately apparent.
An unexpected finding is a generally hich protein bound iodine
value (mean value for the population of 9.4 wg/100 mi.)

The explanation

for this is not apparent, particularly in view of the fact that the people
do not clinically appear to be hyperthyroid.

Serum cholesterols and creati«

nine levels were found to be within normal limits.
