Background: In-patients inadequate food intake can worsen the prevalence and degree of malnutrition.Patients and methods: A “one day” questionnaire was used in medicine (M-Dpts) geriatric (G-Dpts) and surgery (S-Dpts) departments of a university hospital to: i) evaluate nutritional status with the Detky score, ii) quantify food intake, iii) understand the reasons of non-consumption of in-patients (n 286, 46 & 104 in M-, G- & S-Dpts, res...

Introduction: Osilodrostat is a new 11 ß-hydroxylase inhibitor with a mode of action analogue to metyrapone. It has become increasingly used in recent years for treatment of Cushing’s Syndrome (CS). However, few in vivo studies are currently available to accurately compare both drugs characteristics. The objective of our study was to compare steroidogenic profiles in patients treated by either Osilodrostat or Metyrapone for ACTH-dependent CS.Me...

Introduction: Biological diagnosis of Cushing syndrome relies on three parameters: 24 hours-free urinary cortisol; serum cortisol after 1 mg dexamethasone suppression test; late-night serum or salivary cortisol. These tests allow the diagnosis of cortisol excess but do not help in etiological diagnosis, particularly in the distinction between pseudo-Cushing and ACTH-dependent Cushing syndrome, which is often challenging. The aim of this study was to evaluate the performances o...

IntroductionFasting trial remains the gold standard to confirm the diagnosis of insulinoma, based on low blood glucose level concomitant with inadequate high insulin level. However, diagnostic criteria are not consensual. Glycemia and insulin thresholds differ between the different consensus statements : endogenous hyperinsulism diagnosis relies on a glycemia < 3 mmol/l associated with an insulin level > 3 mUI/l in Endocrine Society guidelines (2009)...

Objective: Large response of steroids precursors, including 17-hydroxyprogesterone and 11-deoxycortisol, to ACTH has been described in adrenocortical tumors, suggesting the existence of intra-tumoral enzymatic deficiencies. This study aimed to compare steroidogenic enzymes activity in unilateral and bilateral benign tumors using serum steroid profiling in HPLC-MS/MS in basal state and after ACTH 1-24 stimulation.Design and Methods: A serum profile of sev...

Introduction: The gold standard for insulinoma diagnosis is still 72-hours fasting trial with the aim to trigger Whipple’s triad. In this context, biological diagnosis of endogenous hyperinsulinism relies on the occurrence of a hypoglycemia, concomitant with inadequate high insulin and C-peptide levels. However, diagnostic cut-offs are not consensual among the different learned societies (Endocrine Society 2009, NANETS 2010, ENETS 2012). The objective of this wor...
