Cushing’s syndrome is a rare disorder in children and adolescents. The diagnosis can be a challenge for the clinician, as its principal feature – obesity – is extremely common. We present three cases diagnosed in the last 20 years. The first one was a boy aged 17 that presented in 1984 with central obesity, acne, moon face with plethora, abdominal striae, easy bruising and skin atrophy. The investigations performed consisted in cortisol and ACTH plasma measureme...

Introduction: Continuous subcutaneous insulin infusion (CSII) therapy in type 1 diabetes (T1D) reduces the risk of hypoglycemia. Hypoglycemia remains a treatment-limiting factor. Impared hypoglycemia awareness (IHA) occurs in 25% of T1D cases and seems to be underestimated by continuous glucose monitoring (CGM). Glycemic variability (GV) is a increasingly valued parameter as a predictor of hypoglycemia and risk of chronic complications.Objective: Analysi...

Background: In type 1 diabetes (T1D), quality of life (QoL) and the effectiveness of treatment influence each other. QoL has been associated with glycaemic control assessed by HbA1c in T1D on continuous subcutaneous insulin infusion (CSII), but data on the relationship between Continuous Glucose Monitoring (CGM) metrics and QoL are scarce.Objectives: To assess QoL and the association between CGM metrics and QoL in T1D on CSII.Metho...

Introduction: Inferior petrosal sinus sampling (IPSS) has been considered to be the gold standard for differential diagnosis of Cushing’s Disease (CD) and ectopic ACTH secretion (EAS).Aim: To describe the experience of our centre in performing IPSS, its safety and efficacy; assess remission rates from transphenoidal surgery and clinical course; approach to the difficulty in the etiological diagnosis of ACTH-dependent Cushing’s Syndrome.<p c...

Introduction: Pheochromocytoma is a rare catecholamine-secreting tumor that arises from the chromaffin tissue of the adrenal medulla. Of the reported cases, only 10% consist in bilateral lesions and the probability of multiple endocrine neoplasia should always be investigated.Case report: Female patient, 19 years old, presented with a clinical history with 2 years of evolution, characterized by episodes of palpitations, headache and abdominal discomfort....

Introduction: Neuroglucopenic hypoglycaemia might be an underestimated threat of bariatric surgery, as Roux-en-Y gastric bypass (RYBG) or gastric sleeve. We aimed to evaluate glucose variability after bariatric surgery by continuous glucose monitoring (CGM) in a real-life setting.Methods: CGM was used in twelve patients with clinical suspicion of hypoglycaemia after undergoing bariatric surgery (RYBG or sleeve), during seven days. CGM was through using i...

Introduction: Cushing’s disease (CD) is characterized by increased secretion of ACTH often as a result of a pituitary adenoma. The surgical success rates after transsphenoidal pituitary surgery (TSS) range from 53 to 96% in different centres. Postoperative cortisol levels have been proposed as the standard criteria for prediction of surgical remission however, this variable is subject of a variety of interferences.Objectives: Evaluate the potential ...

Introduction: Factitious hypoglycemia results from surreptitious administration of insulin or insulin secretagogues. It can involve non-diabetic individuals with knowledge of hypoglycemiant drugs, or diabetics manipulating the doses.Clinical case: A 42-year-old women, type 1 diabetic since the age of 14, on intensive insulin therapy (A1C: 8.5%), was hospitalized for study of recurrent severe hypoglycemia in the last 2 months, despite successive insulin d...

Introduction: Traumatic brain injury (TBI) is considered a rare cause of pituitary dysfunction. Recently, some retrospective studies demonstrated that TBI-mediated hypopituitarism is more frequent than previously known. However, its prevalence and natural history are still unclear.Objectives: To evaluate the prevalence of hypopituitarism 1 year after TBI and the association between the seriousness of the traumatism and the pituitary deficits.<p class...

Introduction: The interaction between obesity and bone metabolism is complex and not fully understood. Historically, higher body weight was considered to be protective against osteoporosis. This association has affected clinical practice: body mass index (BMI) is one of the variables included in Fracture Risk Assessment Tool (FRAX), where a higher BMI leads to a lower fracture risk. Despite this association between bone mineral density (BMD) and body weight, it is not clear wh...
