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), ...

Introduction: Germline mutations in tumour suppressor gene PTEN cause heterogeneous phenotypes, that comprise the spectrum of PTEN-hamartoma tumour syndrome (PHTS). Manifestations include macrocephaly, developmental delay, cutaneous lesions, intestinal polyposis and increased risk of neoplasms. Thyroid nodules are identified in about 75% of patients and follicular cell-derived cancer affects 35% of cases, some of which diagnosed as early as 7 years old.C...

Objective: To evaluate continuous subcutaneous insulin infusion (CSII) in type 1 diabetes using the analysis of epidemiological variables, treatment indications, metabolic results, acute and chronic complications and causes for therapy suspension.Methods: A retrospective descriptive study of patients with type 1 diabetes treated with CSII therapy in our institution.Results: A total of 49 type 1 diabetic patients who had been treate...

Introduction: Somatostatin analogs (SS-analogs) are the treatment option when there is a persistent disease despite surgical intervention. They can be also recommended as a first line treatment if surgery is not appropriate (non-curative or contraindicated surgery).Objetive: To evaluate the effect of first-generation SS-analogs (lanreotide and octreotide) on tumour shrinkage and biochemical control in naive patients.Methods: We per...

Introduction: After menopause, an abrupt drop in estrogen levels happens, while ovary androgens secretion declines gradually with aging. This relative hyperandrogenism may lead to the development of hyperandrogenic symptoms. However, the development of marked hirsutism and/or symptoms/signs of virilization, make necessary a detailed study in order to rule out tumorous cause (from adrenal glands or ovaries).Case report: 58 years old woman with progressive...

Objective: The aim of this study is to evaluate the effectiveness of once-weekly exenatide on metabolic control, weight, blood pressure, and lipid profile in obese patients with type 2 diabetes (T2DM), and to assess possible predictive factors of response.Material and methods: Retrospective observational study, conducted with adult obese (BMI ≥30 kg/m2) T2DM subjects that had been initiated once-weekly exenatide following routine clinica...

Introduction: Hyperthyroidism is an endocrine condition with multiple causes. Paraneoplastic hyperthyroidism due to marked overproduction of human chorionic gonadotropin (hCG) by choriocarcinoma is a rare diagnosis, which results from the homology of the alpha subunit of hCG to TSH.Clinical case: A 33-year-old man, with a history of cryptorchidism and orchidopexy in infancy and a euthyroid thyroid nodule, presented with nausea, constipation, and abdomina...

An 18-years-old woman without medical history was referred for study of hypertension and an adrenal incidentaloma. The family history was significant for essential well-controlled hypertension in her father; diagnosed at 39 years-old. The patient complained of headache, asthenia, edema in lower limbs, high blood pressure values (200/150 mmHg) for one year (well controlled with losartan 100 mg/12 h, amlodipine 10 mg/24 h and doxazosin 4 mg/24 h) and marked facial acne previous ...
