[The structural-functional status of the thyroid in patients with nodular goiter evacuated from the 30-kilometer zone of the Chernobyl Atomic Electric Power Station].

An analysis was performed of results of ultrasonic and hormonal investigations in 239 patients with nodular goiter revealed in a screening-type clinical and laboratory examination of the 3371 persons evacuated from the 30-km zone of ChNPP, at their ages randing between 18 to 68 years. In 84.20% of patients in the group who took part in the elimination of effects of the Chernobyl accident (PEEA)--"PEEA + the evacuated"--the diameter of the nodules did not exceed 1 cm, in 6.1% it ranged from 1 to 2 cm, and in 13.41% it exceeded 2 cm. Distribution of nodules in the group "the evacuated" did not differ much from that in the above group. In 20% of patients with nodular goiter, there were functional disturbances concurrent with the autoimmune processes. No effects were detected of small doses of extra irradiation on the pattern of structural-and-functional indices in patients with nodular goiter evacuated from the 30-km zone of ChNPP who took part in EEA.
