BackgroundDevelopment and application of novel drugs frequently fail due to adverse changes of TH-levels or thyroid histology in animal experiments. Such effects potentially arise from interference with thyroid gland function or key regulators of local thyroid hormone (TH) transport, metabolism and action. Deiodinases are key enzymes in TH in-/activation, with impact on development, cell differentiation and energy metabolism among other physiological pro...

PurposeThe standard treatment of hypothyroidism is levothyroxine (LT4), which is available as tablets or soft-gel capsules in Denmark. This study aimed to investigate Danish endocrinologists’ use of thyroid hormones in hypothyroid and euthyroid patients.MethodAn e-mail with an invitation to participate in an online survey investigating practices about substitution with thyroid hormones was sent to all me...

Despite the availability of synthetic thyroid hormone for therapeutic use, a significant number of patients with hypothyroidism do not feel well on replacement doses of thyroid hormones suggesting that better individualized therapy is needed. For this reason, hypothyroidism resulting from congenital lack of functional thyrocytes, surgical tissue removal, or gland ablation, represents a particularly attractive endocrine disease target that may be conceivably cured by transplant...

Induced radiofrequency thermal ablation is cytoreductive treatment of symptomatic benign thyroid nodules, metastatic and recurrent thyroid tumors and papillary thyroid microcarcinomas. It is a safe and effective alternative to surgery and it allows to obtain satisfactory results in terms of volumetric reduction of the nodule with significant improvement in the quality of life. The trans-isthmic approach and the moving shot technique are the two basic techniques; however, an ad...

Radioiodide 131I (RAI) is the therapy of choice for radioiodine-avid differentiated thyroid cancer (DTC). However, 5–15% of DTC patients become RAI refractory (RAIR), and the 10-year survival rate for metastatic disease decreases to 10%. The failure of RAI response is mainly due to the loss of thyroid differentiation, that leads to the loss of expression/function of components of iodide metabolism, first of all the Na/I symporter (NIS). The finding that the MAPK pathway i...

BackgroundMedullary thyroid carcinoma (MTC) accounts for 3–5% of thyroid cancers, but recurrent MTC, manifested by elevated calcitonin levels, is a common problem. We aimed to perform a calcitonin washout procedure simultaneously with cytological evaluation and compare their effectiveness to diagnose metastatic lymph nodes.Methods94 patients diagnosed with MTC were recruited from our institutional datab...
