Acromegaloidism is a very rare entity (have been 54 cases reported worldwide) that presents with clinical acromegaly and normal somatotropic axis, without findings of pituitary or extrapituitary tumour. Its origin has not been clearly established, although it is associated with several pathophysiological conditions. The local ethics committee approved to perform an observational and multicenter study in three hospitals from a region with approximately 800 000 people over 18 ye...

Objective: To assess the association between empty sella (ES) and primary autoimmune hypothyroidism, and the possibility of a common pathogenesis.Patients and methods: We retrospectively studied all patients with presumed ES diagnosed in the last 20 years, most of whom were treated and followed up by our Endocrinology Department. Subjects with a known aetiology were excluded. Incomplete records or those with a doubtful diagnosis were also excluded. A tot...

Neuromedin U (NMU) is a brain-gut peptide originally isolated from porcine spinal cord, and later found in other species. NMU acts through two receptors named NMU1R (abundant in peripheral tissues) and NMU2R (apparently restricted to specific brain regions). Besides its potential implication in the control of stress responses, NMU is abundantly expressed in the ventromedial hypothalamic area and has been involved, as satiety factor, in the regulation of food intake. Very recen...

Introduction: Insulinoma, despite its low incidence of 0.4%, it is the most common functioning pancreatic neuroendocrine tumor. Most are benign, solitary and sporadic. Around 10% can be malignant and 5-10% are part of MEN-1. On certain occasions, the differential diagnosis is difficult when there is a history of Diabetes Mellitus (DM). Our objective was to describe clinical-epidemiological data and its diagnostic-therapeutic management.Materials and Meth...

Introduction and objectives: In the 4th Workshop on Primary Hyperparathyroidism, it is recommended to perform BMD by DXA of third radius as well as lumbar spine and hip DXA in the initial assessment and follow up of patients with primary hyperparathyroidism. This test is not available in many centers, which means that only T Score values of the lumbar spine and hip are used to certify the absence of osteoporosis in asymptomatic patients wich conservative management is...

Introduction and objectives: Having frequent hypoglycaemias can enable the appareance of severe and unnoticed hypoglycaemias, as well as favouring vascular damage in these patients. Our objective is to evaluate de incidende of severe hypoglycaemias (SH) in patients with Diabetes Mellitus type 1 and the reduction of perceived hypoglycaemias.Material and methods: A prospective study was conducted. Patients attending to their Endocrinology appointments betw...

Introduction: Family hypobetalipoproteinemia (HBF) is a rare genetic disorder, in 50% of cases are due to mutations APOB gene, which leads to decreased values of total cholesterol, low density lipoprotein (LDL-cholesterol) and apo-B. It is inherited as an autosomal dominant and heterozygous carriers are usually asymptomatic.Clinical case: Thirty-two-year-old male with abdominal pain and diarrhea associated with food, no relevant history and physical exam...

Introduction: Assessing the effect of GLP 1 receptor agonist on metabolic control and weight loss in obesity and type 2 diabetes patients.Description of methods: A retrospective descriptive study involving type 2 diabetes patients and BMI >30 kg/m2, who started treatment with GLP-1-RAs during the years 2012–2014. Variables analyzed: weight and HbA1c at the begging, 6 months, 1 and 2 years; regimen at baseline and after GLP-1-RAs; inci...

Introduction: Myxoid tumors of the adrenal glands constitute an unusual entity and should be part of the differential diagnosis of atypical adenomas in the study of adrenal incidentaloma.Description of methods: We report the finding of myxoid adrenal adenoma in left adrenal gland in a 38-year-old woman.Case: PMH: Active smoker. Non hypertension, type 2 diabetes or dyslipidemia. No constitutional symptoms.Phys...

Introduction: Familial hypocalciuric hypercalcemia (FHH) has been classically characterized as an asymptomatic disease with mild hypercalcemia, hypocalciuria and inappropriately normal or high serum PTH concentration. The aim of our study is to assess the utility of genetic testing in patients with suspected FHH with atypical clinical manifestations, and the validity of classical biochemical parameters for the diagnosis.Description of methods: A retrospe...
