Introduction: Significant hyponatremia may evolve in hypothyroidism, when however, elevated ADH levels have not been consistently demonstrated. On the other hand, it was shown that thyroid hormone substitution suppresses ADH, and its surrogate marker copeptin secretion. The aim of our present study was to investigate the possible humoral changes in a special model of resolution of short term severe hypothyroidism in differentiated thyroid cancer (DTC) patients.<p class="ab...

Human breast cancer tissue is able to concentrate estrogens. 17-beta-estradiol (E2) and estrone (E1) are produced locally through several mechanisms, e.g. from conjugated and unconjugated steroid hormones uptaken from the circulation. This study was aimed to investigate the correlation between endogenous serum sex steroid concentrations and tumour receptor status in postmenopausal breast cancer patients undergoing surgical intervention. The study involved 740 postmenopausal pa...
