[Medical treatment of nodular goiter].

An optimal supply of iodine--150-200 microg/day--has not yet been secured in all regions and in all phases of life. The appreciable diminishment in thyroid gland mass in children and adolescents is, however, indicative of an improvement in this situation. In elderly persons, however, prophylactic measures do not result in struma or nodule regression. Nodules are found in some 40% of women and 28% of men older than 45. Medical treatment of nodular goiter is aimed at achieving a reduction in size or preservation of the status quo. Depending on the size of the goiter, iodine-deficiency goiter is treated with iodine or a combination of iodine and levothyroxine. In view of the pathogenesis and the marginal alimentary lack that still persists, there are no adequate arguments for L-thyroxine monotherapy of uncomplicated iodine-deficiency goiter.
