There are a number of thyroid disorders in this previously iodine-deficient region. Further studies are required to investigate the change of thyroid disorders during iodine supplementation programs.

Replacement therapy of hypothyroidism with T4 plus T3 does not improve mood and cognitive performance compared to the standard T4 monotherapy. There is even a higher risk of signs of subclinical hyperthyroidism associated with impaired well-being of the patients, which is clearly caused by significant fluctuations in the steady-state fT3 serum concentrations.

The intraoperative probe technique is feasible in patients with pHPT and limited diagnostics for the location of parathyroid adenomas with concomitant goiter. This diagnostic technique identified the parathyroid adenoma in all cases, and thus rendered a bilateral neck exploration obsolete.
