      Hi, all. I just got an email from my son that had me roaring with laughter. Thank goodness for email!

      PUZZLEMANIA: This was a “Graves” puzzle because of the butterflies, right???

      Anyway, REDHEN, I was organizing my thyroid information files today and came across something I pulled from the web when I was first diagnosed. I don’t know where I found it unfortunately, but it DID include the names of specific studies to support their conclusions. These studies had to do with various questions about the safety of RAI. The studies:

      Saenger EL, Thoma GE, Thomkins EA. “Incidence of Leukemia following treatment of hyperthyroidism: Preliminary report of the cooperative Thyrotoxicosis Follow-up Study.” JAMA 1968; 205:147-152.

      Holm LE, Dahlqvist I, Israelson A, et al. “Malignant thyroid tumors after iodine-131 therapy: A retrospective cohort study.” N Engl J Med 1980;303:188-192.

      Hamburger JI. “Management of hyperthyroidism in children and adolescents.” J Clin Endocrinol Metab 1985;60:1019-1024

      Henneman G, Krenning EP, Sankaranarayanan K. “Place of radioactive iodine in treatment of thyrotoxicosis.” Lancet 1986;1:1369-1372.

      The article summarized the findings of these studies as follows:

      “The studies directed at evaluating the safety of radioiodine therapy have failed to show any significant carcinogenic, leukemogenic or teratogenic effect in doses used to treat hyperthyroidism. Interestingly, the prevalence of thyroid carcinoma may be lower in patients who received therapeutic doses of radioiodine as compared to the general population. This is in contrast with the increased prevalence of benign and malignant thyroid nodules in patients who received low dose external beam irradiation or irradiation from atomic bomb or nuclear accidents.”

      If I come across anything else, I’ll let you know.

      Wishing all a superb day,

      Bobbi –
