Retrospective clinical studies of 211 thyreotoxic patients having received 131I-therapy were performed and processed by computer. The patients' mean age was 58 years, the male-female ratio 7.1 to 1. The incidence of symptoms and associated diseases was in agreement with data in the literature. Of the clinical symptoms, weight loss, weakness, fatigability, a fine tremor, decompensation and nervousness, called attention to the condition. Of the ECG changes, an absolute arrhythmia of atrial fibrillation and extrasystole may be indicative of hyperthyroidism. Clinically, there is an essential difference between juvenile and old-age thyrotoxicosis. Differences could also be noted between patients with toxic adenoma and those with non-toxic one. Toxic adenoma patients were more advanced in age and the female-male ratio was higher than in non-toxic cases. Absolute arrhythmia of atrial fibrillation, extrasystole, repolarization disorders, diabetes, hypertension and arteriocardiosclerosis occurred more often, while ophthalmopathy and immune disease were less frequent. The clinical picture may raise the suspicion of old-age thyrotoxicosis. Following laboratory diagnosis, treatment should be administered without delay.

PMID:Experience with 131I-therapy. Hyperthyroidism in old age. 367 Oct 18

The records of 25 patients older than 75 years of age with the diagnosis of hyperthyroidism were reviewed. The mean age of the group (22 women and three men) was 81.5 years, the eldest being 95 years old. Twenty-one patients had Graves' disease, three had multinodular goiter, and one had toxic adenoma. Major presenting symptoms included weight loss (44 percent), palpitations (36 percent), and weakness (32 percent). The average number of thyrotoxic symptoms was only two per patient. Two patients were asymptomatic. Clinical signs included fine skin (40 percent), tremor (36 percent), atrial fibrillation (32 percent), and tachycardia (28 percent). The thyroid was palpable in only three patients with Graves' disease. Mean blood thyroxine level was 15.6 micrograms/dl (range, 11.5 to 24); blood triiodothyronine level was elevated in only half of the patients. One patient had triiodothyronine toxicosis. Mean 24-hour radioiodine uptake was 52 percent. Five patients had normal uptake. No correlation could be established between age, clinical symptoms, signs, and hormone blood levels. Because signs and symptoms of hyperthyroidism in the very old may be too subtle for clinical diagnosis, all elderly subjects should have periodic screening of blood thyroxine levels.
