Objectives: Evaluate the benefit of postsurgical radioactive iodine (RAI) in patients with differentiated thyroid cancer (DTC) at low to intermediate risk of recurrent disease in whom not routinary use of RAI is recommendedMethods: We retrospectively evaluated 1316 patients with DTC diagnosed between 2009-2015. ATA low (LR) and intermediate (IR) risk were included in the study (PTC: tumor size > 1 cm, microscopic extrathyroidal invasion, <5 micro...

Background: Graves’ ophthalmopathy (GO) is an autoimmune disease that affects particularly the retrobulbar soft tissues and represents the most common extrathyroidal manifestation of Graves’ disease (GD). Some studies suggest that GO in newly diagnosed patients in recent years has a trend towards a less severe clinical presentation, moreover we have no studies that focus the trend of clinical presentation of GO in the last decade on the population of our area.<p ...

Background: The well-differentiated grade 3 neuroendocrine tumor (G3NET) category was introduced in the 2017 WHO classification as a new category of high-grade neuroendocrine neoplasm (NEN). G3NET is thought to have worse overall survival (OS) than lower grade NET, but better OS than poorly differentiated neuroendocrine carcinoma (NEC). However, challenges in pathologic diagnosis and changes in terminology have limited our understanding of the G3NET category. We compared outco...

Introduction: Antiresorptive treatment can preserve bone mineral density (BMD) in patients with primary hyperparathyroidism (PHPT) when surgery is not feasible or desired. We aimed to compare the impact of zoledronate vs denosumab on bone-related biochemical parameters in this population.Methods: We analyzed preliminary data from our ongoing randomized trial on osteoporotic postmenopausal women with PHPT who are being treated either with zoledronate 5 mg...

Introduction: Environmental pollutants especially those endowed with endocrine disrupting activities have been shown to contribute to metabolic related diseases suggesting that hormonal deficit conditions as observed in post-menopausal women may constitute aggravating conditions. To explore this hypothesis, we used the model developed in the laboratory which consists in a chronically exposure of mice to low-dosed chemicals in mixture incorporated in a high-fat-high-sucrose die...

Introduction: Increased B12 deficiency among T2DM patients using metformin has been reported. Holotranscobalamin (HoloTc), the bioactive form of B12, is proposed as a specific and sensitive marker of B12 deficiency. Methods to evaluate vitamin B12 deficiency in these patients remain controversial.Methods: First, we studied the prevalence of vitamin B12 deficiency in a group of 106 T2DM patients treated by Metformin, not supplemented by B12. Antacids were...

Introduction: DOTANOC is a largely used somatostatin analogue in NETs investigations. In NODAGANOC, the DOTA is replaced by NODAGA, a chelator derivative from NOTA which is the ‘gold standard’ for Ga3+ and Cu2+ chelation because it forms more stable complexes than DOTA.[1] The aim of our study is to evaluate the affinity of NODAGANOC for somatostatin receptors (sst) and to develop a 68Ga and 64Cu labelled NODAGANOC for a fu...

Background: Glucocorticoids are prescribed for >3 months to 1% of the UK population, principally to control inflammation. In 10–30% of patients, chronic glucocorticoid treatment suppresses HPA axis activity, causing atrophy of the adrenals and a failure to mount an adequate response during stress (potentially fatal) and following treatment withdrawal. Understanding the mechanisms resulting in HPA axis failure may allow us to predict those at risk, inform treatment str...

Introduction: There are few data on renal function following bariatric surgery. We evaluated the effect of Roux-en-Y gastric bypass (RYGB), adjustable gastric banding (AGB) and sleeve gastrectomy (SG) on renal function over a 5-year post-operative period. We also evaluate the effect of these procedures on remission of diabetes and hypertension.Methods: Analysis of a prospectively collected database at Lille University Hospital. Patients were assessed pre...

Irisin is a myokine correlated with lean body mass, despite its association with cardiovascular events (Mantzoros 2014). Increased muscle volume and lipoatrophy have been reported in female FPLD (Ji JCEM 214). Our aim was to determine whether irisin could help to distinguish certain lipodystrophic obesities from FPLD.Methods and patients: Circulating irisin levels (EIA Phoenix) were measured in 20 LMNA-related FPLD, 19 normal-weighed controls (H) and 13 ...
