Purpose: Persistence of well-differentiated thyroid carcinoma most commonly involves cervical lymph nodes. The purposes of the study were to evaluate the ability of FDG-PET/CT imaging to localize residual disease in initial stage M0 thyroid carcinoma thyroid cancer patients and to compare FDG-PET/CT to neck US.Methods: FDG-PET/CT and neck US results of 93 patients were retrospectively analysed. All FDG-PET/CT were performed during thyrotropin stimulation...

Purpose: The widespread use of high resolution cross-sectional imaging such as computer tomography (CT) and magnetic resonance imaging (MRI) for the investigation of the abdomen is associated with an increasing detection of incidental adrenal masses. 18F-fluorodeoxyglucose positron emission tomography (FDG-PET) has proved to be an efficient tool in the diagnosis and follow-up of malignancies. We evaluated the ability of FDG-PET to distinguish benign from malignant adrenal mass...

Despite significant progress in understanding the regulation of phosphate (Pi) homeostasis over the past 20 years, the mechanisms underlying the very early step leading to the regulating cascade involving multiple hormones (PTH, vitamin D, FGF23) and organs (kidney, intestine, bone, parathyroid glands) are not deciphered. Progress in this area is based on on the ability to identify and characterise the Pi-sensing mechanism in mammals that allow cells or organisms to detect cha...

Aim of the work: Impaired Hypoglycemia Awareness (IHA) is associated with an increased risk of Severe Hypoglycemia (SH) in adults with diabetes but is less known in youth. The purpose of this study was to determine the prevalence of IHA and its clinical characteristics in a cohort of children and adolescents with type 1 diabetes.Methods: This prospective observational study of two-month duration included all eligible subjects with type 1 diabetes attendi...

Introduction: Generously supported by IPSEN)-->Craniopharyngiomas (CP) are benign tumors that arise from remnants of the Rathke’s pouch. Classically, they are classified as cystic or calcified tumors. The presence of hormonal receptors in CP has been reported in in vitro studies but only eight cases growing during pregnancy have been published in literature.Case report: We report a 32-year-old wom...

Background and aims: Patients with AVPR2 gene mutations present nephrogenic diabetes insipidus (NDI) resulting to a severe deficit in urine concentration despite high levels of circulating Antidiuretic Hormone (ADH). The mutation in codon 106 of the AVPR2 gene leading to the substitution of arginine by cysteine (R106C) is known to produce a mild disease while in vitro characterization revealed a complete loss of function. We report the case of a 24-year-old male member ...

Object: Pheochromocytomas and paragangliomas (PPGLs) are rare tumors that are responsible for an inappropriate production of catecholamines. They are heritable in 40% of cases and can integrate different genetic syndroms. Thus, there are several interests to detect them precociously: avoid comorbidities due to the catecholamine hypersecretion, search syndroms and manage their related manifestations and screen the families. The objectives of this study were to separate PPGLs in...

Background and aim: Insulin tolerance test (ITT) is the gold standard for the diagnosis of cortisol and growth hormone deficiencies in adults. Once hypoglycaemia (<40 mg/dl) is achieved, some medical centers give sugar to their patients (food, drink or glucose infusion), others do not and let the blood glucose rise spontaneously. Although critical hypoglycaemia results in discomfort and potential complications for the patients there is so far no recommendation on the subje...

Global knockout models of the androgen receptor (ARKO) illustrates the many roles androgens and their receptor have in the development of male reproductive organs and the gender differences in many features like the musculoskeletal system. However, neither the global ARKO nor orchidectomy models discriminate between direct and indirect effects of androgens. To determine direct and indirect effects of androgens on muscle, we developed a muscle-specific ARKO (called satARKO for ...

Ojective: We characterized the onset and follow-up of hypophysitis in a cohort of 612 patients treated for a cancer by antitumoral immunotherapy between june 2010 and may 2017 in CHU Lille, France. Design and patients: 612 patients treated by anti-CTLA4 and or antiPD-1 for melanoma (n=426), lung cancer (n=166), hematological cancer (n=19) or maxillary epidermoid cancer (n=1).Methods: Follow-up of patients treated by im...
