ABSTRACT Medullary thyroid carcinoma (MTC) is a rare neuroendocrine tumor originating from parafollicular C cells of the thyroid and associated with mutations in the proto-oncogene REarranged during Transfection (RET). The prognosis of MTC depends on clinical stage, with a 95.6% 10-year survival rate among patients with localized disease and 40% among patients with advanced disease. Standard chemotherapy and radiotherapy have no significant impact on the overall survival of these patients and two tyrosine kinase receptor inhibitors (TKIs), vandetanib and cabozantinib, […]

Clonidine stimulation test is widely used to evaluate growth hormone secretion. Side effects are somnolence (35%) and arterial hypotension (AH) (5%). The aims of this paper were to evaluate the tolerance to this test regarding blood pressure (BP) decrease, sedation and the efficacy of saline resuscitation to prevent AH. BP was measured at basal, 60 and 120 min. Sedation was determined by the Ramsay scale. Patients were divided into two groups: Group 1 (n= 80) received saline resuscitation only upon […]
