Background: Adrenocortical cancer (ACC) is an aggressive tumour with heterogeneous prognosis. Recently integrated genomics reported distinct genomic alterations: transcriptome “C1A” (high expression of proliferation/cell cycle-related genes) vs “C1B”, “CIMP” (CpG islands hypermethylation) vs “non-CIMP”, chromosome alterations “Noisy” (numerous and anarchic alterations) vs “Chromosomal” (extended patterns of loss of he...

Introduction: Most thyroid nodules are benign. Some studies have shown largest nodule size, specially >4 cm, can predict malignancy and reduce fine needle aspiration (FNA) accuracy. Recent studies, however, have shown conflicting results as to whether nodule size may be used to distinguish at risk-lesions. We attempt to determine whether nodule size predicts thyroid malignancy and to examine accuracy of fine needle aspiration (FNA) by size.Material a...

The diabetogenic risk associated with statin therapy is higher in patients with pre-existing risk factors, such as metabolic syndrome (MS).Objective: To assess changes in lipid and glycemic profile in dyslipidemic subjects with MS after statin therapy.Methods: Observational, retrospective, multi-center study, conducted in 40 endocrinology Spanish hospitals. Each endocrinologist included the first 10 patients >18 years with MS, ...

Introduction: Hyperparathyroidism-jaw tumor (HPT-JT) syndrome is a rare autosomal-dominant disorder caused by mutations in CDC73 tumor suppressor gene. To date about 80 mutations in CDC73 have been described.Case reports: Four patients among a cohort of young patients (<40 y.o.) with primary hyperparathyroidism (PHPT) underwent next-generation sequencing (NGS) (Ion TorrentTM PGMTM, Thermo Fisher Scientific&#150...

Introduction: UK guidelines state that all patients undergoing adrenalectomy for phaeochromocytoma must be admitted to intensive care post-operatively due to the risk of haemodynamic instability (HDI). Intensive care beds are a scarce resource and it is important to regularly evaluate the need for admission, preventing unnecessary admission.Methods: The study population included all patients who underwent adrenalectomy for phaeochromocytoma at a UK terti...

Introduction: Gestational diabetes (GD) is associated with a significantly higher risk of perinatal complications. It has been suggested that third-trimester (3thT) foetal abdominal circumference (fAC) determination is an important predictor of macrossomia and large for gestational age (LGA).Aims: The purpose of this study was to evaluate the association between the 3thT fAC percentile with birthweight (BW) and adverse neonatal outc...

Objective: We investigated the clinical usefulness of thyroid blood flow measurement by colour-flow Doppler ultrasonography in predicting relapse of Graves’ disease (GD).Patients and methods: In 30 euthyroid GD patients, (eight males and 23 females), aged 17–68 years (mean 43.8±12.8), after at least 1 year of treatment with anti-thyroid drug (ATD) and just before its withdrawal, we evaluate with colour-flow Doppler ultrasonography the colo...

Introduction: ACTH-independent macronodular adrenal hyperplasia (AIMAH) is often an incidental finding, but may be diagnosed in patients with Cushing’s syndrome. We have recently identified germline mutations in the armadillo repeat containing 5 gene (ARMC5) in AIMAH patients, associated with somatic second hits specific of each AIMAH nodule ( Assié et al, NEJM, 2013). The aim is to characterize the prevalence of ARMC5 mutations in AIMAH patients and the gen...

Hypoparathyroidism is a rare disorder characterised by hypocalcaemia and hyperphosphataemia in the presence of low or inappropriately normal parathyroid hormone levels. Currently there are limited data on the burden of illness and healthcare resource utilisation (HCRU) associated with chronic hypoparathyroidism in Canada. A retrospective cohort analysis with matched controls was conducted to examine HCRU in patients with chronic hypoparathyroidism in Ontario, Canada. Data were...

Introduction: The length of the insulin needle in last three decades has reduced from 16 mm to 4 mm. The BMI of 10 kg/m2 difference accounts for a 4 mm difference in subcutaneous tissue thickness. We compared the glycemic control in patients switched from 4 mm needle to 6 mm needle in the Normal Weight (NW) patients (BMI < 25 kg/m2) with the Obese and Overweight (OOW) patients (BMI ≥ 25 kg/m2)</...
