Introduction: Cinacalcet is a positive allosteric modulator of the calcium sensing receptor successfully used to decrease serum calcium in primary hyperparathyroidism (pHPT) patients in the short-term, but long-term data are scarce. In this single-centre retrospective analysis, we investigated the efficacy and safety of cinacalcet in pHPT patients who received more than 5 years of treatment.Methods: Statistical analysis was performed using free online so...

Primary generalized glucocorticoid resistance or Chrousos syndrome is a rare disorder, which affects all tissues expressing the human glucocorticoid receptor. It has been defined by an absence of overt Cushing’s syndrome (CS) signs (no skin weakness, muscle atrophy, or osteoporosis) associated with biological hypercortisolism consisting of high urinary free cortisol (UFC) and an absence of negative feedback loop of cortisol on HPA, defined as 8-AM cortisol level >50 n...

Mesonephric adenocarcinoma (MA) is an uncommon gynecologic tumor that are thought to arise from embryonal remnants of the mesonephric ducts, also known as Wolffian ducts. Mesonephric-like adenocarcinoma (MLA), despite absence of Wolffian origin, have similar morphology and immunophenotype and exhibit molecular aberrations like MA. These tumors are generally negative for estrogen and progesterone receptor.Case Report: An 83-year-old Spanish female was ref...

Objetive: To assess the clinical features of incidental clinically non-functioning pituitary adenoma (NFPA) and to analyze its natural history.Methods: A multicenter retrospective study in patients with NFPA followed-up from 1992 to 2015 was performed.Results: Fifty-seven patients were studied (29 women (50.9%); age 55.8±16.7 years. 43.9% were older than 60 years, 40.3% belonged to the age group of 40–60 years and 15.8% w...

Objective: To assess clinical outcome after pituitary surgery in patients nonfunctioning pituitary adenomas (NFPA) surgically treated in the past 3 decades in three tertiary referral hospitals.Methods: A multicenter retrospective study on clinical and pathological characteristics, treatment patterns, and outcome in patients with NFPA periodically followed up in specialized neuroendocrinology units who underwent surgery in the period 1982–2015 was pe...

Background: Primary bilateral bilateral macronodular adrenal hyperplasia is a cause of Cushing’s syndrome. It is characterised by a large enlargement of the adrenal glands at the expense of multiple non-pigmented nodules. There is inefficient steroidogenesis.Summary of the case: A 58-year-old woman with a history of extreme obesity, type 2 diabetes mellitus, hypertension and dyslipidaemia was admitted to our hospital for cellulitis and anaemia secon...

Background: Systematic exploration for anterior pituitary deficiency in patients harboring pituitary microadenomas is not well defined. So far, little is known on the involvement of pituitary function in clinically non-functioning pituitary microadenomas (CNFPM).Objective: To evaluate the prevalence of anterior pituitary insufficiency, defined as at least one hormonal deficiency, in patients diagnosed of CNFPM.Patients and methods:...

Introduction: Hyponatremia is the most common electrolyte disorder and it affects approximately 5% of adults and 35% of hospitalized patients. Diagnostic and/or therapeutic challenge is given. It is defined by a serum sodium concentration of less than 136 mmol/l. Symptoms of hyponatremia range from mild and nonspecific to severe and life-threatening. Hyponatremia is classified as mild, moderate and severe and may be acute or chronic. Mortality and morbidity are significantly i...

Introduction: Although the first-line treatment of insulinoma remains to be surgical resection, medical therapy is necessary for non-localizable or non-resectable tumors, poor surgical candidates, or when surgery is declined. We present an interesting case of a patient with well-controlled insulinoma on diazoxide for 5 years who presented acutely with diabetic ketoacidosis (DKA).Case presentation: A 85-year-old female presented to the Emergency Departmen...

Introduction: Circulating insulin levels are widely used to provide diagnostic information for diabetes mellitus and hypoglycaemic syndromes. C-peptide concentration provides an accurate assessment of residual B-cell function and reliable information about insulin secretion in patients with diabetes. The aim of this study was to evaluate the performances and reliability of the Liaison® fully automated system for measurement of insulin and C-peptide concentratio...
