Advances in diabetes technology, particularly the introduction of continuous subcutaneous insulin infusion (CSII) pumps and of subcutaneous glucose sensing devices, have transformed the Type 1 diabetes (T1D) management landscape over the last 20 years. These devices have become more commonplace in our clinical practice, yet the evidence base that they have contributed to the modest improvements in glycaemic control in children and young people with T1D over these last two deca...

Background: Congenital adrenal hyperplasia (CAH) is a group of disorders caused by defects in one of the enzymes in the adrenal steroidigenic pathways. The most common form is 21-hydroxylase deficiency which leads to decreased production of cortisol and aldosterone and increased androgen production. Close monitoring of treatment is important so that adrenal suppression is achieved without excessive exposure to glucocorticoids. The current gold standard for monitoring in CAH is...

Purpose: Non-Obstructive Azoospermia (NOA), occurring in approximately 1% of men, has an unknown etiology in the majority of cases. This study aims at evaluating the diagnostic efficiency of a gene panel contemplating all known genes associated with azoospermia in mice.Subjects and methods: Design of a ‘mouse azoospermia’ gene panel through the consultation of MGI; selection of 175 mouse azoospermia genes with human orthologues; selection of 31...

Objective: Various features have been identified as predictors of relapse after complete resection of pheochromocytoma, but a comprehensive multivariable model for recurrence risk prediction is lacking. The aim of this study was to develop and internally validate an integrated predictive model for post-surgical recurrence of pheochromocytoma.Methods: The present research retrospectively enrolled 177 patients affected by pheochromocytoma and submitted to ...

Pheochromocytomas and paragangliomas (PPGL) are commonly benign catecholamine-producing neuroendocrine tumors (NETs); however, up to 25 % of patients develop distant metastases or aggressive behavior. The current classification of PPGL comprises pseudohypoxia-profile, MAPK-pathway alteration, and Wnt-pathway dysregulation clusters according to their genomic characterization. However, to date, there are no biomarkers to help stratify patients based on their prognosis. Alternati...

Introduction: Bariatric surgery is associated with improvement and often resolution of type 2 diabetes mellitus (T2DM). Our aim was to compare the effects of gastric banding (GB) and gastric bypass (GBP) in glucose homeostasis in obese patients with T2DM.Methods: From 1995 to 2011, 83 diabetic patients underwent bariatric surgery at our hospital: 37 underwent GB (73% females, mean age 48.3±9.2) and 46 underwent GBP (82.6% females, mean age ...

omatostatin, originally isolated from ovine hypothalami in 1973, and cortistatin, identified a decade ago in amphibians and then in human and rodents, are two highly related peptides thought to derive from a common ancestor gene. Owing to their high structural homology, both peptides bind with similar affinity to the five so-called somatostatin receptors (sst1-sst5), and exert virtually undistinguishable effects on several physiological targets, including inhibition of endocri...

Introduction: Disorders of Sex Development (DSD) can be associated with an increased risk of germ cell tumours depending on the underlying diagnosis. To date however knowledge regarding the indications and timing of gonadectomy is lacking.Methods: The I-DSD Registry was interrogated for anonymised information regarding the diagnosis, karyotype, sex of rearing and timing of gonadectomy, if undertaken, of all individuals of any karyotype who were over the ...

Background: Adrenal insufficiency (AI) results from deficient production/action of glucocorticoids (GCs), with or without deficiency of mineralocorticoids (MC) and adrenal androgens. GC treatment is essential but some patient needs MC therapy to allow sodium(Na+) retention, potassium(K+) excretion and to maintain normal plasma volume and blood pressure. Much attention has focused on optimization of GC replacement but no consensus exists for optimization o...
