The advantages of subtotal thyroidectomy and suppression of TSH in the primary treatment of papillary carcinoma of the thyroid.

Patients between the ages of 6 and 45 years with distant metastases from papillary carcinoma of the thyroid can be treated as effectively by subtotal thyroidectomy and suppressive doses of thyroid hormone as by total thyroidectomy followed by treatment with iodine 131 (131I). Moreover, distant metastases can be treated by either 131I or suppression as effectively after they are apparent on x-ray as they can be when treated in a subclinical stage. Therefore, in patients younger than 45 years old it is rarely necessary to perform a total thyroidectomy or to do frequent postoperative scans.

Immunologic studies in two patients with persistent lymphocytic thyroiditis, thyrotoxicosis, and low radioactive iodine uptake.

Two patients with persistent lymphocytic thyroiditis and thyrotoxicosis were studied. Both patients presented with severe hyperthyroidism of nine months' duration and had nontender, small thyroid glands. Uptake of radioactive iodine (131I) was consistently low.

A simple semiquantitative radiometric measurement of antithyroglobulin antibodies in human serum. Comparison with hemagglutination method.

A simple solid-phase radiometric assay for the measurement of thyroglobulin autoantibodies (TgRA) was developed and evaluated. The assay is semiquantitative, and the results were expressed as a ratio between sample versus negative control (normal human serum). In 59 normal subjects, the mean ratio was 0.
