Introduction: Adrenocortical carcinoma is a rare tumour, with an annual incidence of 1 to 2 case per million. Hypercortisolism constitutes the predominant clinical manifestation in patients with hormone excess, presenting in 50% to 80% of all adrenocortical carcinomas. Non-functioning tumors are even rarer, comprising only 20% of adrenal carcinomas in the largest reported series. Conversely, Addison’s disease is also an infrequent disorder, with estimated incidence rates ...

Introduction: Adrenal masses (AM) are being increasingly diagnosed but only a small portion will need surgical treatment.Methods: We retrospectively reviewed patients referred to the Endocrinology Clinic that underwent adrenalectomy between 1996 and 2023.Results: We included 57 patients. Most AM were diagnosed incidentally (53%) and had a median size of 32 (25) mm. Forty (70%) patients had hormonal hypersecretion (HH): pheocromocyt...

Introduction: A rare cause of hypoglycemia is non-islet cell tumor hypoglycemia (NICTH), a paraneoplastic syndrome caused by tumoral overexpression of insulin-like growth factor 2 (IGF-2) and pro-IGF-2.Case presentation: : A 57-year old woman presented with odd behavior each morning that improved after breakfast and extensive weight loss (13 kg in 3 years). The patient was hypoglycemic (2.6 mmol/l) with low insulin levels (<1.39 pmol/l) and C-peptide...

Introduction: COVID-19 has taken on pandemic proportions. Phase angle (PhA) and Standardized phase angle (SPhA) have been related to mortality and severity in several diseases.Objetives: To determine the predictive role of PhA and SPhA on 90 days survival of adults with COVID-19.Methods: A longitudinal cohort study with 127 consecutive patients diagnosed with COVID-19. We collected PhA, SPhA, body composition (fat mass, fat free ma...

Introduction: The parathyroid gland is made up of principal cells and oxyphilic cells, surrounded by stroma, whose main component is adipose tissue, which accounts for 25% of the content of the parathyroid in adults. In parathyroid adenomas, prominent parathyroid cellularity can be observed, with a very marked decrease in the stroma. Parathyroid lipoadenoma is a rare variant of parathyroid adenoma, characterized by hyperfunctioning parathyroid cells in an abundant fatty stroma...

Introduction: Insulinomas are pancreatic neuroendocrine tumors (PNET), characterized by insulin hypersecretion syndrome with the development of hypoglycemia. The incidence of the tumor is 3-10 cases per million inhabitants. The average age of onset is 40-50 years old, being more frequent in women. Case Reports: We present a clinical case of a patient with CREST syndrome and difficult-to-control hypoglycemia. Female patient, 81 years old, with a history o...

Introduction and objectives: Metformin (MTF) is the most used oral antidiabetic drug for the treatment of type 2 diabetes (T2D). However, intolerance to drug is frequent and limits its use. There are controversies about the cause of this problem, the gut microbiota has been proposed to be responsible. The gradual introduction of MTF could exercise an adaptation of gut microbiota that would facilitate tolerance to MTF. In this study we evaluate the metabolic changes and gut mic...

Insulin autoimmune syndrome (IAS) is a very rare cause of hypoglycaemia in western countries. One proposed mechanism is anti-insulin antibody capture of prandial insulin followed by the dissociation of insulin from anti-insulin antibody. The first objective was to study the relationship between glucose, insulin and C-peptide during a prolonged glucose load in two patients with active IAS. The second was to study the variation of these parameters between the active and the reco...

Objectives: This study evaluated the prebiotic effect of a moderate intake of extra virgin olive oil (Evoo) and red wine (Rw) polyphenols on modulating the gut microbiota composition and the improvement of metabolic risk factors in obese subjects with high insulin resistance (HIR).Methodology: 10 obese patients with HIR (HOMA-IR>5.5) and 10 lean subject with low insulin resistance (HOMA-IR< 3.3) were included in a randomized and controlled interv...

Introduction: Data on body composition in patients with achondroplasia are scarce. The Phase Angle (PA) is a bioelectric measurement of our body cells. The PA is considered to be a global prognostic factor that gives information about cellular function in relation to body composition.Objectives: To describe body composition parameters PA, standardized PA (sPA), resistance (Rz), reactance (Xc), body cell mass (BCM), total body water (TBW), fat mass (FM), ...
