Nonvisualization of sterile surgical incisions with indium-111 labeled leukocytes.

The localization of In-111 labeled leukocytes (WBCs) in recent surgical incisions was studied in 18 patients. In-111 WBC images correlated well with culture results and clinical findings. No accumulation of In-111 WBCs was detected at the site of noninfected incisions in nine patients.

Solitary cold thyroid nodule: cost-ineffectiveness of ultrasonography.

We reviewed our experience with thyroid sonography of 60 patients with nonfunctioning (cold) solitary thyroid nodules proven by iodine 123 scan. Twenty-two patients had surgery; the remaining 38 had thyroid scan and ultrasound only. In the first group, the echograms did not demonstrate the surgically proven nodules in seven patients (32%).

Radiobiological effects of 131I and 125I on the DNA of the rat thyroid. I. Comparative study with emphasis on the postradiation hypothyroidism occurrence.

One of the major disadvantages of the use of 131I in the treatment of thyrotoxicosis is the development of hypothyroidism. Alternatively, 125I has been proposed for thyrotoxicosis therapy, and was thought to be preferable to 131I because of the short range of its emitted soft electrons. Several studies have shown 125I to be as effective as 131I in the treatment of thyrotoxicosis, and equally likely to produce hypothyroidism.
