Introduction: Hypopituitarism is a rare diagnosis that is mainly due to primary pituitary neoplasms and their treatment. There are rarer causes such as hemorrhage/ischemia, traumatic brain injury, infections and infiltrative lesions. Clinical case: We herein present an 18-year-old male patient diagnosed with acute promyelocytic leukemia at the age of 14, with no evidence of central nervous system invasion in several lumbar punctures during his follow-up....

Background and aims: Obesity is a chronic multifactorial disease characterized by an excessive accumulation of body fat resulting from an imbalance between energy intake and caloric expenditure. Uncoupling protein 2 (UCP2) is located in the inner mitochondrial membrane and plays an important role in the regulation of energy expenditure. NLR family, pyrin domain-containing 3 (NLRP3) inflammasome seems to have a key role in obesity-induced inflammation through production of the ...

Introduction: The glycogen storage disease (GSD) is a rare disorder of carbohydrate metabolism resulting from the defective synthesis and utilization of glycogen. GSD-1a is a subtype of GSD caused by a deficiency in glucose-6-phosphatase activity, which leads to decreased conversion of glucose-6-phosphate to glucose. The dominant features at presentation are hypoglycemia and lactic acidemia. Long-term complications include blood glucose lability, lactic acidemia, short stature...

Introduction: Prolactinomas are mostly benign tumours usually managed with pharmacological treatment. Some, however, seem to be resistant to dopamine agonists (DA) for unclear reasons. The relationship between T2W signal intensity (T2WSI) and response to treatment with somatostatin analogs is well described in acromegaly patients. Some evidence suggests that prolactinoma’s T2W hypointensity might be related to higher baseline prolactin levels and more resistance to DA.</p...

Introduction: Recent studies seem to support a bidirectional positive interaction between aldosterone and parathyroid hormone (PTH). Understanding the normal physiological relationship between renin-angiotensin-aldosterone system (RAAS) and PTH is of clinical interest because their inappropriate activity may negatively impact cardiovascular and skeletal health.Objective: To evaluate the presence of an interaction between aldosterone and PTH in a cohort o...

Introduction: Autoimmune Addison disease requires lifelong glucocorticoid and mineralocorticoid replacement. Optimal therapy is not standardized and must balance adequate hormone substitution with prevention of treatment-related complications.Objective: Assessment of patients followed at our department: epidemiology, associated conditions, treatment, cumulative hydrocortisone dose and comorbidities.Methods: Review of clinical recor...

Introduction: Insulinomas are the most frequent cause of hypoglycemia and the most common functional endocrine pancreatic tumors. Whipple triad is often present and should alert to the diagnosis.Case report: A 36-year-old male was admitted in the emergency room with loss of consciousness, diaphoresis and blurred vision, and hypoglycemia (50 mg/dl). The patient recalled recurrent symptoms of diaphoresis, tremors and palpitations, sometimes with loss of co...

Introduction: Pheochromocytoma is one of the major secondary causes of hypertension. The classic triad of pheochromocytoma symptoms of headache, sweating and tachycardia is not present in a high percentage of patients and is sometimes diagnosed as incidentaloma or atypical presentations.Case report: The authors present a 56-year-old man, with no known diseases, referred to Endocrinology evaluation by incidentaloma of the right adrenal gland, from the Pne...

Background and Aim: Unacylated ghrelin (UAG) is the major form of circulating ghrelin. Initially considered as a non-functional peptide, soon after UAG has been associated to a negative action on energy balance, suppression of hepatic glucose production and decrease in circulating levels of insulin. The aim of this study was to analyze the association between the serum levels of UAG and glucose metabolism parameters in obese women, independently from the eventual interference ...

Introduction: Secondary causes of diabetes refer to a category in which diabetes is associated with other diseases. They are thought to constitute less than 2% of the total cases of diabetes.Case report: A 56 year-old caucasian man, with no relevant medical history, presented to the Emergency Department with fatigue, polyuria, polydipsia, polyphagia and involuntary weight loss (6 kg in two weeks). He was hemodynamically stable and exhibited a glycaemia o...
