Objective: Smoking may be associated with changes in metabolic risk factors and sex hormones in PCOS.Design: Retrospective trans-sectional study.Patients: Six hundred and fifty caucasian premenopausal women with the diagnoses hirsutism or PCOS were divided according to smoking status: Non-smokers (NS-PCOS=390) and smokers (S-PCOS=260). 119 healthy women were studied as controls (NS-Control=105, S-Control=14)....

Background: The indication for testosterone therapy in ageing hypogonadal men without hypothalamic, pituitary or testicular disease remains to be elucidated. The aim of this study was to investigate the effect of testosterone therapy on insulin sensitivity, substrate metabolism, body composition and lipids in ageing men with relative hypogonadism using a predefined cut-off level for bioavailable testosterone.Methods: A randomized, double-blinded, placebo...

Introduction: Graves’ disease is associated with mild hypercalcemia in about 1/5th of cases. T3, through its nuclear receptor activates osteoclasts resulting in accelerated bone turnover. Although mild hypercalcemia is common in Graves’ disease, symptomatic hypercalcemia is rare. We describe a case who presented with thyrotoxic storm and hypercalcemia.Case report: 52-year-old lady presented with thyrotoxic symptoms of weight loss, dysphagia for...

Short synacthen test (SST) is the most widely used dynamic test of hypothalamic-pituitary-adrenal (HPA) axis function. It’s simple to conduct but requires nursing time and is relatively costly given 15-fold price increase in synacthen since 2015. We audited our SST use with the aim of reviewing clinical indications for testing and identifying useful predictors of test outcome. Baseline referral, clinical and biochemical data were retrospectively collected for individuals ...

Current lifestyle, characterized by physical inactivity and a poor diet, is heavily linked with an increased incidence of metabolic diseases. One of the most serious silent co-morbidities of those diseases is infertility. The hormonal link between food intake and energy homeostasis is mediated by the leptin ghrelin axis. Compelling evidence suggests that direct leptin’s action regulates cellular glucose homeostasis and mitochondrial biogenesis. We have recently shown that...

Background: The H-syndrome is a recently described very rare monogenic systemic autoinflammatory autosomal-recessive genodermatosis with young onset of diabetes without evidence of autoimmunity. It is caused by mutations in the SLC29A3 gene, which encodes the equilibrative nucleoside transporter hENT3.Objectives: To study the clinical features and confirm the genetic diagnosis in a subject with young onset of diabetes.Subject and m...

Introduction: A multi-disciplinary endocrine Adolescent Transition Clinic (ATC), with key professionals from paediatric and adult services, was instituted at the Royal Hospital for Sick Children, Glasgow, in October 2008 serving young people in the West of Scotland. A good transition should improve clinic attendance, health outcomes and quality of life into adulthood.Aim: To systematically review the success of ATC in engaging young people following thei...

Objective: Sex steroids play an important role in the maintenance of bone health. However, there is limited information on the association between sex hormones and age-related bone loss in men. Our objective was to study the relationship between sex steroid levels and the changes accompanying aging process, including bone mineral density (BMD), muscle strength and body composition in elderly Egyptian men.Methods: Free testosterone (FT), estradiol (E...

Metabolic dysfunction-associated fatty liver disease (MAFLD) is a growing cause of hepatocellular carcinoma (HCCs); however, the molecular characteristics of MAFLD-derived HCCs are still to be elucidated. To provide novel insights in this field, we performed the first quantitative proteomic analysis of HCC samples from different aetiologies. Particularly, cytosolic and nuclear proteome of liver tissues from HCC patients (n=42; HCC vs adjacent tissue) and healthy contr...

Mice with dominant-negative mutations of thyroid hormone receptor α1 (TRα1) are euthyroid but display growth retardation and delayed bone age as juveniles and increased bone mass during adulthood, indicating impaired skeletal thyroid hormone responsiveness. The first autosomal dominant mutations affecting TRα1 in humans were recently described in two unrelated children and one parent who were euthyroid apart from a low T4:T3 ratio. Consiste...
