Introduction: Adult growth hormone deficiency (AGHD) is associated with lower bone mass and likely with increased risk of fragility fractures. GH replacement leads to increase in bone mineral density (BMD) and trabecular bone score (TBS). The effect of adequate levels of vitamin D during GH replacement is important to provide effect on TBS.Aim: To assess long–term effectof recombinant GH replacement on BMD and TBS with regards to vitamin D levels d...

Serum calcitonin (CT) screening of thyroid nodules is a highly sensitive test for early diagnosis of medullary thyroid carcinoma (MTC) and is used for initial diagnosis and post-surgical follow-up. MTC is neuroendocrine tumor derived from parafollicular C cells which produce calcitonin. It is a rare tumor, accounting for 5-10% of all thyroid carcinomas, with a favorable prognosis if diagnosed early. A 74-year-old patient was referred to our clinic due to elevated basal CT leve...
