Introduction: Women with a high breast density have an increased risk of breast cancer, which prevalence increases after menopause in obese subjects. Breast density can be calculated on mammograms as the proportion of dense tissue (percent mammographic density-PMD). Several factors may influence the PMD, including age, menopausal status, body mass index (BMI), and bone mineral density (BMD) taken as an index of overall estrogen exposure. However, conflicting data have been rep...

Introduction: Pituitary adenomas, second most common brain tumors, are mostly well controlled after surgery. However, some pituitary tumors present an aggressive evolution and are resistant to standard management. Immunotherapy with inhibitors of T-cell checkpoints have shown durable efficacy in a variety of malignancies. Moreover, immunotherapy has been associated with treatment-related hypophysitis, suggesting that pituitary could be a target of these treatments. Recently, i...

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: Delayed new-onset Graves’ orbitopathy (GO) or worsening of existing GO occurs in approximately 15–20% of patients following radioiodine treatment (RAI), mostly within 12 month.Case Report: A 57-years-old woman was referred in April 2016 to our endocrinology department for Graves’ disease hyperthyroidism. Relevant medical history included chronic lymphocytic leukemia (2004), fludarabine-related interstitial pneumonia with tempor...

Introduction: Measurement of microRNA (miRNA) in aldosterone-producing adenoma (APA) tissue from primary aldosteronism (PA) patients show levels of the miR24-1 cluster miRNAs (i.e. miRNAs 24-1, 27b and 23b) are significantly reduced relative to normal adrenal tissue. Our previous studies also show that miRNA-24 directly targets CYP11B2 (aldosterone synthase) gene expression. Circulating miRNAs released into the bloodstream may be diagnostic biomarkers or signalling mo...

Background: Both prevalence and incidence of type 1 diabetes (T1DM) is increasing. T1DM is associated with other autoimmune diseases, such as Addison’s disease (AD). This combination is rare, with estimated prevalence in Norway 20 per million. Having both DM & AD is associated with marked excess mortality.Objectives: To study prevalence and incidence of AD among patients with and without T1DM.Methods: Nationwide, observati...

Idiopathic Isolated ATCH deficiency (IIAD) is a rare cause of secondary adrenal insufficiency characterised by ACTH deficiency with otherwise intact pituitary function. Our objective was to describe the presentation, the autoimmune associations and diagnostic findings observed in IIAD. We present a case series of 19 cases of idiopathic Isolated ACTH deficiency which were identified from the National Pituitary Register in Ireland. A chart and biochemical review was performed to...

A rapidly growing neoplastic mass of the neck can either be caused by an anaplastic thyroid cancer (ATC) or a primitive lymphoma of the thyroid gland (PLT). These two malignancies share the same clinical features but vary widely in their treatment and outcome. Only histologic criteria through biopsy can provide a definitive diagnosis. The aim of this study was to assess biological and radiological differences between ATC and PLT in order to hasten differential diagnosis. Sixty...

Approximately 10% of essential hypertension cases is attributed to primary aldosteronism (PA), where inappropriately high levels of aldosterone are secreted. Almost half of these PA cases result from aldosterone-producing adenoma. microRNAs are single-stranded, short non-coding RNAs that negatively regulate gene expression post-transcriptionally. In a previous study, we showed that microRNAs directly modulate CYP11B2 (aldosterone synthase) gene expression and aldoster...

Introduction: Patients with mutations in the Succinate Dehydrogenase Complex Subunit B (SDHB) gene are predisposed to neuroendocrine tumours such as parangangliomas, phaeochromocytomas and gastrointestinal stromal tumours. Individuals who are carriers but have no manifestation of disease require regular surveillance. Our tertiary endocrine service provides follow up/surveillance for these patients and we cover a wide geographical area throughout the West of Scotland.<p cla...
