In overt or subclinical ACTH-independant Cushing’s syndrome (CS), aberrant adrenal receptors may control cortisol secretion.We systematically studied the 20 patients with adrenal incidentaloma screened in our department for illegitimate adrenal receptors between 2000 and 2006. We investigated plasma cortisol level during successive stimulation tests performed while dexamethasone was given orally every 8 h (upright posture, meal, hypothalamic hormone...

Introduction: The syndrome of reduced sensitivity to thyroid hormone (SRSTH) due to mutations of thyroid hormone receptor β (TRB) consists of an inappropriate secretion of TSH with elevated levels of thyroid hormones. Cardiovascular manifestations are often the ones that affect patients. Our aim was to evaluate the cardiac and vascular characteristics of patients with SRSTH due to TRB mutations.Materials and methods: We analysed cl...

Within the group of gonosomal aneuploidy, the 47,XXY Klinefelter syndrome is a well-known chromosomal anomaly with a clearly delineated phenotype. Since the 48,XXYY polysomy is rather rare and associated with hypogenitalism, it has often been considered as a variant of the Klinefelter syndrome. Nevertheless, several differences have been reported, in particular the greater severity and prevalence of mental retardation and psychiatric illness in patients with a 48,XXYY syndrome...

Ectopic adrenocorticotropin secretion (EAS) accounts for 10–15% of cases of Cushing’s syndrome and comprises a spectrum of lesions from highly malignant tumours to a variety of less aggressive neuroendocrine tumours. Selective removal of the primary lesion is the optimal management. It is therefore mandatory to localize the source of ectopic ACTH.As no single test is accurate enough to distinguish the ectopic from the pituitary sources of ACTH,...

Reputedly, thyroid hormones make thinner and change the body composition. The aim of this randomized and prospective study was the assessment of the effect of levothyroxine suppressive therapy on body composition in women with benign thyroid nodule.Method: Thirty seven euthyroid and non obese women (18–60 years old) with benign thyroid nodule (fine needle cytology and calcitonin measurement) were randomized into 2 equal groups. The first group recei...

IntroductionProgressive and radioiodine-refractory thyroid cancer has poor outcomes and limited therapeutic options (i.e tyrosine kinase inhibitors) due to the transient efficacy of treatment and toxic effects. Therefore, combinatorial treatment with new therapeutic approaches are needed. Many studies link G Protein-Coupled Receptors (GPCRs) to cancer. The aim of this study is to present the first specific atlas of GPCRs expression in progressive and ref...

Background: Hyperphagia leading to craniopharyngioma-related obesity (CRO) is a common and serious sequel of treatments of craniopharyngiomas. The few therapeutic approaches that have been tested until now for the control of eating behaviour and weight have poor efficacy. Glucagon-like peptide-1 (GLP-1) analogues might be an option. Methods: This multicentre, randomised, double-blind superiority trial was conducted in France. Adults with CRO (BMI > 3...
