Introduction: Tyrosine kinase inhibitors (TKI) demonstrated clinically significant activity in radio iodine (RAI)-refractory differentiated thyroid cancer (DTC) and in locally recurrent, unresectable and metastatic medullary thyroid cancer (MTC). The natural history of MTC and DCT is quite variable with rates of disease progression ranging from a few months to many years. TKI can be associated with progression-free survival, but is not curative and the side effects may have a ...

IntroductionPrimary Hyperparathyroidism (PHPT) results from one or more parathyroid glands hyperfunction. It is recommended that the preoperative location of the parathyroid lesion be performed with cervical ultrasonography and sestamibi-scintigraphy. Recently 4-Dimensional Computed Tomography (4D-CT) has revealed anatomic, morphologic and functional precision for detecting those lesions, either for typical or ectopic location. This study evaluates the d...

IntroductionDiabetes mellitus (DM) and older age are frequent comorbidities as well as factors associated with poorer outcomes in patients with Coronavirus disease (COVID-19). The reason for worse prognosis in patients with diabetes is likely to be multifactorial.Objectives We aimed to evaluate clinical characteristics and their impact on the outcomes of elderly patients with and without DM hospitalized with ...

IntroductionIt has been estimated that prevalence of vitamin D deficit (25(OH)D) in the world is between 20 and 100%, depending on age group, ethnicity and region. In European population, the prevalence is around 40%. The Endocrine society guidelines recommend the supplementation of vitamin D when vitamin D deficiency is confirmed. The objective of this work is to evaluate the effect of 25(OH)D supplementation on phospho-calcium metabolites: calcium (Ca)...

Mesenchymal stem cells (MSCs) are multipotent stromal cells that can differentiate into various types of cells including chondrocytes, osteoblasts and adipocytes. Since these types of cells are simultaneously derived from the same precursor cell, adipogenesis and osteoblastogenesis are thought to be counter-related. It is well-known that chronic treatment of steroid can induce Cushing’s syndrome which has phenotypes like visceral adiposity and osteoporosis. Cell fate of d...

Introduction: Hypercalcaemia secondary to malignancy is rare in children. PTH-rP secreted by malignant cells increases bone resorption and renal calcium retention causing hypercalcaemia. We report a case of hypercalcaemia refractory to bisphosphonate and corticosteroid therapy, but responsive to treatment with Denosumab.Case report: A 17-year-old boy with epidermolysis bullosa presented with advanced squamous cell carcinoma of the left leg and symptomati...

Hyponatremia is a common disorder, especially among the elderly, and an important morbidity and mortality cause. Empty sella syndrome, on the other hand, is a rare entity, more common in women between their fourth and sixth decade of life, and endocrine dysfunction has been reported in 10–60% of the cases. A 68-year-old man, with a past medical history of essential hypertension and glaucoma, presented at the emergency room due to malaise, asthenia, somnolence and anorexi...

Introduction: The Sodium Iodide Symporter (NIS) is responsible for active transport of iodide into thyroid follicular cells, enabling the use of radioactive iodine (RAI) for treatment of metastatic disease. Still, a significant proportion of patients with advanced forms of thyroid cancer (TC) became refractory to RAI therapy. Defective NIS expression is the main reason for impaired iodide uptake in TC and NIS downregulation has been associated with several pathways linked to m...

Introduction: Diabetic ketoacidosis (DKA) is characterized by the triad – ketonemia, metabolic acidosis and hyperglycemia. It is typically associated with type 1 Diabetes Mellitus (T1D) and the most common culprits are infections and poor therapeutic compliance.Clinical Case DescriptionThe present case deals with a 25–year–old female patient, with T1D diagnosed in 2008, without microvascular or macrovascular compl...

Introduction: Patients with Down syndrome are vulnerable to autoimmune thyroid disease and progression from Graves’ disease (GD) to Hashimoto’ thyroiditis or vice-versa may be more frequently seen in this population, specially at a younger age. In the last years questions have been raised regarding the distinction of this metamorphic scenario from a single entity: autoimmune thyroiditis with TRAbs that trigger opposite functional actions.Case...
