Introduction: MODY 5 is a rare form of autosomal dominant monogenic diabetes with a broad phenotypical spectrum that occurs with pancreatic and extra-pancreatic clinical manifestations, such as: malformation and dysfunction of the pancreas, nephrourologic anomalies, impaired renal function, hepatopathy and neurocognitive defects. It is caused by a mutation of the gene encoding hepatocyte nuclear transcription factor 1 beta (HNF1β).Case 1: M...

Introduction: Clomiphene citrate (CC), a selective estrogen receptor modulator that increases LH and FSH secretion, improves hypogonadism and fertility outcomes. Moreover, there is limited evidence that it may also be helpful as add-on therapy to normalize IGF-1 levels in male acromegalic patients.Objective: To assess the effect impact of CC on serum IGF-1 and testosterone levels in male acromegalic patients not controlled by the combination of lanreotid...

Introduction: Differentiated thyroid cancer (DTC) is one of the most frequent forms of malignancy. Because of its favourable outcome and low mortality rates, identifying prognostic factors has been a challenge. Several risk stratification systems have been developed. Most of them include demographic and tumour specific features, as well as extrathyroidal extension. Our objective was to compare clinical characteristics between DTC patients with and without remission.<p clas...

Introduction: Dopamine agonists (DA) are the ideal treatment for prolactinomas and cabergoline (CAB) is the drug of choice, for being much more effective and better tolerated than bromocriptine. However, 10-15% of patients with prolactinomas are considered to be resistant to CAB, as they dot not achieve prolactin (PRL) normalization, while in use of conventional doses of this drug.Objective: To evaluate the effiaccy of increasing doses of CAB in prolacti...

Background: Reduced GLUT4 expression in insulin-sensitive tissues, insulin resistance, inflammation, nonalcoholic steatohepatitis (NASH) and hypertension are pathophysiologic changes expected in metabolic syndrome animal models.Aims: To fully characterize the development and maintenance of metabolic syndrome features over time (GLUT4 in insulin-sensitive tissues, insulin resistance, inflammation, blood pressure and liver changes) in spontaneously hyperte...

IntroductionSimultaneous pancreas-kidney transplantation (PKT) has a beneficial effect on the evolution of chronic complications in type 1 diabetic (T1D) patients with terminal chronic kidney disease (CKD). However, the CKD-mineral and bone disorder (CKD-MBD) remains a frequent complication. There are a few studies addressing the long-term evolution of bone mineral density (BMD) in these patients.AimTo charac...

Introduction: Simultaneous pancreas-kidney transplantation (SPKT) is the treatment of choice for type 1 diabetic patients with advanced kidney chronic disease (CKD), restoring normoglycemia, insulin independence and improving survival. The present study aims to analyse survival of patients undergoing SPKT and the post-SPKT metabolic profile of patients with a functioning pancreatic graft.Methods: Retrospective observational study. T1DM patients with CKD ...

The adrenal cortex is a dynamic organ that undergoes self-renewal. In the mouse it is divided into two concentric layers, the outer zona glomerulosa (ZG) and the inner zona fasciculata (ZF), that secrete aldosterone and corticosterone, respectively. Capsular and subcapsular stem/progenitor cells differentiate and migrate in a centripetal fashion to repopulate the gland until they reach the juxtamedullary region where they undergo senescence and apoptosis. Our lab has previousl...

Background: Immune checkpoint inhibitors (ICI) are an innovative oncologic therapy used in several types of solid and hematological neoplasms. This treatment enables the antitumoral immune system response and results in significant improvement of clinical outcomes and survival rate. However, endocrine related adverse effects (ERAE) have been related, with thyroid and pituitary dysfunction being the most common endocrine diseases described. An association between the surge of e...

Introduction: Accurately discern malignant from benign nodules sometimes represents a real challenge. Fine needle aspiration (FNA) biopsy, ultrasound and The Bethesda System for Reporting Thyroid Cytopathology (BSRTC) allow for accurate diagnosis in 60–80% of all nodules. However, 10–20% of thyroid FNAs yield an indeterminate cytology (BSRTC III and IV categories). The real malignancy rate of BSRTC III category is difficult to ascertain because histopathological anal...
