Introduction: The prevalence of pituitary thyrotropin secreting tumors (TSH-omas) is 1-2 cases per million inhabitants, most of them being macroadenomas. The differential diagnosis may be challenging, especially for microadenomas.Case Report: A 50-year-old male was observed at the endocrinology department with multinodular goiter. He noticed progressive neck enlargement over the previous months but denied other complaints. There was no family history of ...

Aim: Stimulated thyroglobulin (sTg), measured at radioiodine remnant-ablation (RRA) in patients with differentiated thyroid cancer(DTC), is an important predictive factor of persistent disease. However, Tg produced by normal thyroid cells may also contribute to the sTg value.We aimed to study the relationship between sTg-level in RRA and the thyroid remnant size (TRs), using post-therapy whole-body scan (131I-ptWBS), at different TSH stimulation method.<...

Introduction: Obesity is a chronic disease associated with multiple comorbidities, defined by BMI, without considering the metabolic state of the patient. There are few data on the proportion of obese patients without metabolic syndrome (MS).Objective: To characterize patients considered to be metabolically healthy (MH) followed at the obesity outpatient clinic of one University Hospital, and to compare this group with a group of obese patients with MS.<...

Introduction: Cushing’s disease (CD) is a rare disorder caused by an ACTH-secreting pituitary adenoma. Transsphenoidal surgery (TSS) is the recommended first-line treatment. However, an equivocal or even normal preoperative MRI can preclude the surgical management and the outcome of these patients.Objectives: Evaluate the relationship between preoperative MRI and TSS efficacy in patients with CD.Methods: Retrospective cohort s...

Introduction: Continuous subcutaneous insulin infusion (CSII) and multiple daily injections (MDI) are forms of intensified insulin therapy and the most used regimens for type 1 diabetes (T1D). Owing to its continuous basal output, hypoglycaemic events tend to be rarer with CSII. Our goal was to evaluate the differences in nocturnal hypoglycemia between these two treatment strategies.Methods: Retrospective analysis of 61 patients who had performed continu...

In the last years estrogens have emerged as important regulators in male reproductive function. Spermatogenesis depends on the tight control of germ cell apoptosis and several studies indicated estrogens as playing a role in this process. The stem cell factor (SCF), a membrane-bound cytokine, and its receptor (c-kit), and the Fas ligand (FasL)/Fas receptor (FasR) system are powerful mechanisms controlling germ cell proliferation and apoptosis through the direct membrane commun...

Introduction: Cushing’s disease (CD) is rare in children. It’s most common clinical manifestations are growth retardation, changes in pubertal development and weight gain. The diagnosis, based on clinical suspicion, is often hampered by the non identification of the microadenoma in MRI.Clinical history: A 14-year-old male patient, with short stature, growth arrest after 12 years and weight gain since age of 9. At physical examination, he had mo...

Introduction: Hypoparathyroidism is characterized by hypocalcemia and low or inappropriately normal levels of PTH. The most common cause of hypoparathyroidism is iatrogenic due to anterior neck surgery. In recent years it was documented that vitamin D insufficiency is widespread.Aim: To investigate the cause of hypocalcemia in thyroidectomized patients with PTH within the reference range.Methods: Retrospective review of clinical re...

Introduction: Therapeutic approach of patients (pts) with metastatic renal cell carcinoma (mRCC) may include the use of biological agents such as m-TOR inhibitors: temsirolimus (TM) and everolimus (EV). Its use is associated with metabolic dysfunction, especially with everolimus: hyperglycemia (37% TM treated pts vs 72% EV treated pts), hypercholesterolemia (25% TM treated pts vs 81% EV treated pts) and hypertriglyceridemia (30% TM treated pts vs 73% EV treated pts). Discontin...

Introduction: Abnormalities in cell cycle pathways, such as CDKN1B (p27) underexpression, have been identified in the pathogenesis of pituitary adenomas, but their underlying mechanisms have not been elucidated. Ribosomal proteins have been recently related to pituitary tumorigenesis. In gastric cancer, RPS13 down-regulates p27 and promotes cell cycle progression; these mechanisms have not yet been explored in pituitary adenomas.Objective: To evaluate th...
