| The most common cause of goitrous hypothyroidism in adults is: A. Graves' disease. B. Riedel's thyroiditis. C. Hashimoto's disease. |
| The ultrasonographic appearance of both Graves' disease and Hashimoto thyroiditis are similar as well, with both having a hypoechoic and heterogeneous echotexture. |
| Subacute thyroiditis shows a rapidly enlarging thyroid gland and signs of thyroid dysfunction. |
| We conclude that selenium substitution may improve the inflammatory activity in patients with autoimmune thyroiditis, especially in those with high activity. |
| Several researchers have reported possible effects of organochlorinated substances on endocrine autoimmune disorders, including thyroiditis and type II diabetes. |
| The question raised but not fully addressed here is whether patients with Hashimoto's thyroiditis and normal thyroid function should be treated. |
