Purpose: Although growing evidence supports the role of primary cilia (PC) in the regulation of cancer development, their possible role has not yet been studied in pituitary neuroendocrine tumours (PitNETs). The study of cilia could serve as a diagnostic tool providing new insights into the mechanisms of tumorigenesis and aggressiveness of PitNETs. Methods: A total of 86 patients with PitNETs (28 functioning and 58 non-functioning [NF-PitNETs]) and 12 co...

Introduction: Hypogonadotropic hypogonadism is the cause of sexual deficiency, sometimes difficult to differentiate from constitutional growth delay (CGD).Clinical case: A 19-year-old male consulting endocrinology for delayed puberty. Pointed to, at 13 years of age, as having had CGD. His medical report include a viral meningitis at 8 years of age and anosmia since 3 years of age. He expressed lack of sexual desire and concern about the size of his genit...

Introduction: Langerhans cell histiocytosis (LCH) is a rare systemic disease. Diabetes insipidus is the most frequent endocrine alteration and occurs mostly after diagnosis. Others are hypogonadism, growth hormone deficiency (GHD) and alterations in glucose metabolism.Clinical case: A 61-year-old smoker, diagnosed with LCH 9 years ago with pulmonary and hepatic involvement, without treatment, who consulted for asthenia, unquantifiable polyuria, polydipsi...

Introduction: Denosumab is a monoclonal antibody indicated in the treatment of postmenopausal osteoporosis. Hypocalcemia is a rare adverse effect.Case report: We present the case of a 58-year-old woman with a clinical history of bariatric surgery in 2001 and osteoporosis with multiple vertebral and hip fractures. Under treatment with Zinc sulphate, Vitamin A, 25-OH-vitamin D, calcium and iron. She came to the A&E for general malaise, generalized weak...

Introduction: Glycogen storage disease (GSD) type Ia (von Gierke’s disease) is an inherited metabolic disorder of glycogen metabolism, caused by defects in the glucose-6-phosphatase complex, with associated risk of severe hypoglycemia within 3–4 h after a meal.The aim of the present study was to evaluate the efficacy of continuous glucose monitoring (CGM) system in determining the magnitude of hypoglycemia in patients with GSD type Ia.<p cl...

Introduction: Insulinomas are the most frequent cause of endogenous hypoglycaemia. 90 to 95% of these are benign. Surgical enucleation or resection is the standard treatment. Medical therapy focuses mainly on the use of diazoxide with few alternatives in patients with high surgical risk.Case-report: Female patient, 89 years-old, non-diabetic, with previous history of acute myocardial infarction, stroke with motor sequelae, pacemaker carrier and severe ao...

Introduction: Evidence implicates oxidative stress as mediator of diabetic complications. Furthermore, glucose variability (GV) is associated with oxidative stress and inflammation; however, association between GV and diabetes complications remains to be established. Our aim was to assess GV in patients with and without microvascular complications (MVC).Methods: We analysed 2454 and 6593 h of continuous glucose monitoring of patients with type 1 diabetes...

Introduction: Radioiodine (131I, RAI) is a safe and effective option for the treatment of Graves’ disease (GD). However, approximately 20% of RAI treated patients will have persistent disease or will relapse after the first treatment. Our aim was to identify the factors influencing the outcomes in RAI treatment for GD.Methods: We analysed 143 DG patients (116 women) treated with RAI between October 2002 and April 2014 and ≥12 months...

Introduction: Primary hyperaldosteronism (HAP) is the main cause of secondary hypertension, with a prevalence estimated between 6 and 20% in resistant hypertension. Clinical suspicion is critical, especially if aldosterone-to-renin ratio (ARR) >25, however the diagnosis is dependent on confirmatory evidence, including aldosterone suppression tests.Methods: Retrospective evaluation of 44 patients with suspected PAH, identified betwee...

Introduction: Despite being a psychiatric disorder, anorexia nervosa (AN) is associated to severe systemic complications. The endocrine complications of AN are an opportunity for the diagnosis and treatment of this condition. The authors report the experience of the Endocrinology Department in the treatment of AN in inpatient setting.Patients and methods: Retrospective analysis of 45 patients admitted with AN between 2001 and 2015 in the Endocrinology de...
