Background: TSH-suppressive therapy in patients with differentiated thyroid carcinoma (DTC) leads to iatrogenic thyrotoxicosis and may be associated with alterations in body composition and bone mineral density (BMD). Its effects on a sarcopenia in elderly have not been in detail investigated.Objective: The objective was to compare changes in total and areal lean body mass (LBM), body fat mass (BFM) and BMD in postmenopausal female patients with DTC duri...

Purpose: To determine the risk of developing hypopituitarism after cranial irradiation for skull base meningiomas. Cranial irradiation is often chosen as first treatment in skull base meningiomas to avoid risk to proximally-located critical structures. While cranial irradiation has been associated with high risk of inducing hypopituitarism, few studies concern meningiomas.Methods and materials: Fifty-two adult patients receiving photon-beam therapyfor sk...

BackgroundOnly limited data are available regarding adverse effects of gender affirming hormonal treatment (HT) mainly due to the lack of population-based studies with adequate controls, thus making spontaneous reporting systems a valuable tool to detect potential side reactions.ObjectiveIn this nationwide retrospective study, we aimed to analyse adverse drug reactions (ADRs) in relation to gender affirming H...

Background: During the last decennium, an increase in the number of persons referred to gender identity centres has been observed. Epidemiological data have not yet been formally studied in France. Here we report the experience from the Trans’Est Gender Identity Centre of the University Hospital of Nancy.Aim: To study the number of people seeking transgender care, the age at referral and the trends in the sex ratio.Methods: Th...

Background: In females transitioning to males (FtM) and in males transitioning to females (MtF), exogenous cross-sex steroids are prescribed to favour development of secondary characteristics of desired sex, while endogenous hormone production is inhibited.Aims and design: To study early impact of cross-sex steroids on body composition, metabolic profile and pro-inflammatory parameters in young transgender persons before and after 12 months of gender-aff...

Introduction: Metastatic insulinoma is an extremely rare form of malignant insulinoma involving metastatic growth where classical surgical treatment is often impossible. Medical therapies are widely considered and reserved for those especially with inoperable insulinoma with the goals of reducing tumor size, but also of reducing hypoglycemic events either by acting directly on the insulinoma cells (reducing excess insulin secretion from the insulinoma cells or reducing tumor v...

Context: Mosaicism is a feature of several inherited tumor syndromes but is rarely systematically looked for in routine. MEN1 is an autosomal dominant hereditary syndrome characterized by several endocrine tumors affecting parathyroids, pancreas, and anterior pituitary most of the time, due to inactivating mutations in the MEN1 gene. Few cases of mosaicism in Multiple Endocrine Neoplasia type 1 (MEN1) have been described. MEN1 mosaicism is probably under-diag...
