Technetium-99m-sestamibi has been reported to localize in various tumors. Scintigraphic results for a patient with recurrent Hurthle cell carcinoma of the thyroid whose tumor was imaged with both 99mTc-sestamibi and 201TI, but not with 131I, are presented.
Are thyroid function test results affected by the timing of the previous levothyroxine dose? To answer this question, the authors asked 101 consecutive patients when they took the last dose and then correlated the time elapsed with the results of thyroid assays. Their findings are discussed in this article.

Urinary urgency and frequency and even enuresis may be manifestations of augmented adrenergic activity in hyperthyroidism, as are sweating, tremor, and tachycardia. Because patients rarely volunteer problems with urgency, frequency, and enuresis, it is worthwhile for the physician to inquire about such symptoms in patients with moderate to severe hyperthyroidism. Symptoms generally cease after treatment of the hyperthyroidism.

As assay for thyroxine binding globulin (TBG) that measures the thyroxine binding capacity of TBG and other proteins was used to calculate a free thyroxine index (FTI) in 108 consecutive thyroid patients, 2,559 normal patients, and 152 sick euthyroid patients. The TBG assay compared favorably with the triiodothyronine (T3) uptake test in producing a FTI for the clinical evaluation of thyroid patients. In addition, it did not suffer the disadvantages inherent in assays specific for only TBG. In the sick euthyroid population, the TBG assay produced an FTI that was more consistent with the clinical evaluation than did the T3 uptake test.
