Introduction: Tumours with aryl hydrocarbon receptor interacting (AIP) mutations often show an unusually aggressive and invasive clinical course as up to 80% of AIP positive pituitary adenomas have a certain degree of extrasellar extension. The exact mechanisms by which AIP inactivation promotes an aggressive behaviour remain unknown. The majority of adenohypophysis is composed of sinuous cords of epithelial cells and consequently, molecules that can induce remodellin...

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: 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.Clinical case: Female patient, 19 years old, presented with a clinical history with 2 years of evolution, characterized by episodes of palpitations, headache, nausea and abdominal d...

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 stromal luteoma of the ovary is a rare tumour occurring mostly in post menopausal women. Endocrine symptoms and sometimes virilizing signs may be observed, although abnormal vaginal bleeding is the most frequent manifestation. This tumour is surrounded by ovarian stroma being entirely composed of luteinized cells devoid of crystals of Reinke. Hyperthecosis of ovarian stroma is often observed. Its evolution is always benign.Case report: ...

Introduction: Diabetes is a major risk factor for chronic kidney disease (CKD). Previous studies have shown contradictory results regarding the effect of prediabetes in the development of CKD.Methods: We performed a secondary analysis of the SPRINT trial (Systolic Blood Pressure Intervention Trial) involving 9361 patients without diabetes and with an increased cardiovascular risk (clinical or subclinical cardiovascular disease, estimated glomerular filtr...

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...
