A male patient presented at the age of 54 years with metastatic pancreatic neuroendocrine tumour (NET). He was managed with interferon and multiple courses of MIBG therapy which controlled his disease for about seven years. He then developed symptomatic hypoglycaemia which resolved with the introduction of somatostatin analogue treatment and further therapeutic MIBG. However, three years later he...
OBJECTIVE: The investigation of the association between retinol-binding protein 4 (RBP4) and lipoproteins in subjects with hypertriglyceridemia. DESIGN: Forty-six obese or overweight hypertriglyceridemic patients were studied at baseline and 20 of them underwent a hypocaloric low-fat diet for 3 months. RESULTS: Plasma RBP4 levels were positively correlated with serum triglycerides (TG) in the subgroup...
A 43-year-old woman, previously misdiagnosed as having primary hyperthyroidism and treated with antithyroid drugs, presented to us with overt hyperthyroidism, high levels of thyroid hormones and elevated thyroid-stimulating hormone (TSH). Magnetic resonance imaging (MRI) revealed a pituitary microadenoma extending suprasellarly. The patient responded favorably to initial treatment with somatostatin...
PURPOSE: Multiple Endocrine Neoplasia type 2A(MEN2A) is a complex autosomal dominant inherited syndrome characterized by medullary thyroid carcinoma (MTC), pheochromocytoma and primary parathyroid hyperplasia. In patients with only one or two clinical features, identification of a germ line RET (REarranged in Transfection) mutation is required to make the diagnosis and initiate genetic counseling...
OBJECTIVE: Complete surgical resection is the only potentially curative treatment of localized pancreatic neuroendocrine tumors. Unfortunately, a significant proportion of these patients present with unresectable locally advanced tumors or massive metastatic disease. Recently, a new therapeutic approach for this subset of patients has emerged consisting of neoadjuvant therapy followed by surgical...
Two proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors, evolocumab and alirocumab, have recently been approved by both the Food and Drug Administration (FDA) and the European Medicines Agency (EMA) for the treatment of hypercholesterolemia. These fully human monoclonal antibodies selectively block PCSK9, thus permitting the low-density lipoprotein (LDL) receptor to effectively recycle...
Primary Generalized Glucocorticoid Resistance is a rare condition characterized by generalized, partial, target tissue insensitivity to glucocorticoids owing to inactivating mutations, insertions or deletions in the human glucocorticoid receptor (hGR) gene (NR3C1). Recent advances in molecular and structural biology have enabled us to elucidate the molecular mechanisms of action of the mutant receptors...
OBJECTIVE: It is well known that conventional surgery leads to detrimental immune and catabolic responses, thus there is growing interest in the effect of minimally invasive techniques on postoperative endocrine and immune function. The aim of this prospective study was to evaluate the growth hormone (GH)/insulin-like growth factor-1 (IGF-1)/IGF binding protein-3 (IGFBP-3) axis and acute phase (interleukin-6,...
OBJECTIVE: Carney complex (CNC) is a rare autosomal dominant multiple neoplasia syndrome characterized by the presence of endocrine and non-endocrine tumors. More than 125 different germline mutations of the protein Kinase A type 1-α regulatory subunit (PRKAR1A) gene have been reported. We present a novel PRKAR1A gene germline mutation in a patient with severe osteoporosis and recurrent vertebral...
INTRODUCTION: The efficacy of Gamma Knife surgery (GKS) in local tumor control of non-secreting paragangliomas (PGLs) has been fully described by previous studies. However, with regard to secreting PGL, only one previous case report exists advocating its efficacy at a biological level. CASE REPORT: The aims of this study were: 1) to evaluate the safety/efficacy of GKS in a dopamine-secreting PGL;...
BACKGROUND: Multiple endocrine neoplasia type 1 (MEN1) is an autosomal-dominant hereditary disorder associated with the development of endocrine tumors due to reduced expression of the tumor suppressor protein menin. Recent studies indicate a general role of menin in carcinogenesis, affecting the prevalence and clinical course of common non-endocrine tumors such as breast cancer, hepatocellular carcinoma...
OBJECTIVE: In rodents, progesterone (P4) pretreatment increases anxiety and response to stressors. Social isolation is a stressor that generates physiological and behavioural stress responses in sheep. The aim of the study was to compare the stress response of anoestrous ewes previously treated or not with P4 to the social isolation test. DESIGN: Ten ewes received P4 treatment during 13 d (group P4-W)...
The prevalence of diabetes mellitus (DM) is increasing worldwide reaching epidemic proportions. The aim of the present study was to estimate the prevalence of DM in Thessaly, a large region of Central Greece, and to extrapolate our results to the population of the entire country. A random sample of 805 adults (421 females and 384 men) living in Thessaly, aged 18–80 years, was surveyed. After completing...
OBJECTIVE: We evaluated the long-term effects of growth hormone (GH) on markers of quality of life, glucose metabolism, and lipid metabolism to validate the adequacy of long-term GH replacement therapy for adult GH deficiency (AGHD). DESIGN: Eighty-three of 100 sequentially followed patients who received GH therapy were selected for this study. Forty-nine were men aged 26 to 78 years (mean, 52 years)...
