Hypercalcemic Crisis Due to a Giant Intrathyroidal Parathyroid Adenoma, with Postsurgical Severe Hypocalcemia and Hungry Bone Syndrome: A Case Report.

Background: Parathyroid adenoma is the most common cause of hypercalcemia and rarely leads to a hypercalcemic crisis, which is an unusual endocrine emergency that requires timely surgical excision.

Case Presentation: A 67-year-old male was admitted to the ER of the Euroclinic Hospital, Athens, Greece, because of elevated calcium levels and a palpable right-sided neck mass, which were accompanied by symptoms of nausea, drowsiness, and weakness for six months that increased prior to our evaluation. A gradual creatinine elevation and decreasing mental state were observed as well.

The use of recombinant human thyrotropin (Thyrogen) in the diagnosis and treatment of thyroid cancer.

The introduction of human recombinant thyrotropin (rhTSH/Thyrogen) into the diagnosis of thyroid cancer has substantially ameliorated the patient's quality of life through the avoidance of debilitating hypothyroidism. With the aim of updating the use of Thyrogen, we report 7 cases which were treated with Thyrogen for diagnostic or therapeutic purposes. All 7 patients were thyroidectomised and radioiodine ablated and all had detectable [> 1 ng/ml] basal serum thyroglobulin (b-Tg) levels.
