Aim: To analyse outcome of transsphenoidal surgery for acromegaly in Wales using stringent remission criteria.Method: We retrospectively analysed 90 patients who underwent transsphenoidal surgery (performed by 3 surgeons) as initial therapy for acromegaly in our centre between January 1980 and December 2001. A combination of modern, evidence-based remission criteria including mean day curve GH < 5 mU/l and /or a nadir GH < 2 mU/l after an oral glucose tolerance test ...

Background: Depression and anxiety are frequently associated with functional gastrointestinal disorders (FGID), inducing personal suffering and a decreased quality of life. There is limited data in patients with NETs. Therefore, adequate research identifying the prevalence of these mood disorders among GI patients and NETs are necessary to inform holistic clinical management. Further, due to the nature of hospital clinics being fast-paced, quick and effective screening tools a...

Introduction: The Controlled Antenatal Thyroid Screening II (CATS) study, a large randomised trial of thyroxine supplementation for suboptimal gestational thyroid function (SGTF), reported higher attention deficit hyperactivity disorder (ADHD) scores in 9 year-old children exposed to higher thyroid hormone (TH) in utero. We investigated if this was accompanied by altered myelination.Methods: Eighty-five children...

Background: Growth hormone (GH) and Insulin like growth factor 1 (IGF-1) discordance in patients with acromegaly is a well-recognised phenomenon. It is unclear whether this is associated with increased mortality and morbidity compared to patients with concordant normal results.Methodology: A retrospective study was conducted on the United Kingdom Acromegaly Registry (UKAR). A comparison of mortality and morbidity was performed among four groups categoris...

Background: Functioning gonadotroph adenomas (FGA) are rare benign pituitary tumours. Several case reports suggest that FGA may present with features of ovarian hyperstimulation in women. However, a lack of aggregated clinical experience of FGA precludes the meaningful guidance of management in affected women.Methods: Case series of 7 women presenting at different UK sites with FGA induced ovarian hyperstimulation syndrome (OHSS).R...

Objectives: The crystal structures of the TSH receptor (TSHR) leucine rich repeat domain (LRD) bound to TSHR stimulating monoclonal autoantibody M22TM or to TSHR blocking monoclonal autoantibody K1-70TM and antibody free have been solved previously. Cryo-electron microscopy (cryo-EM) was now used to solve the structure of full length TSHR in complex with K1-70TM.Methods: Recombinant human TSHR expressed in CHO cells was i...

In patients with autoimmune Addison’s disease (AAD), exogenous glucocorticoid (GC) therapy is an imperfect substitute for physiological GC secretion; patients on long-term steroid replacement have increased morbidity, reduced life expectancy and poorer quality of life. Recent early-phase studieshave demonstrated that some endogenous steroidogenic function – Residual Adrenal Function (RAF) - is maintained at the point of diagnosis in a proportion of AAD patients; this...

Introduction: Adrenal incidentalomas (AIs) are found in ~3% abdominal scans, rising to 10% in the elderly. In 2016, the European Society of Endocrinology (ESE) published new guidance on their management.Aims & objectives: To (1) compare how AIs have been managed at the University Hospital of Wales (UHW) against ESE guidelines, and (2) provide an early evaluation of the impact of service changes implemented based on initial findings.<p class="abst...

The role of the thyrotropin receptor (TSHR) in bone is unclear. TSHR-deficient mice have low bone mineral density (BMD) and focal osteosclerosis despite normal thyroid hormones (suggesting TSHR function, in bone, is important). Subclinical hypothyroidism (SH) has various aetiologies including thyroid autoimmunity (TA) and inactivating TSHR mutations (TSHR-M). In TSHR-deficiency & TSH-M elevated TSH compensates for reduced TSHR function, whereas in TA it compensates for red...

Background: Treatment of CAH in childhood focuses on growth and development; however the impact of final height (FH) on adult health is not known. We examined the relationship between FH, adiposity, cardiometabolic risk and quality of life (QoL) in a cohort of adult patients.Methods: Cross-sectional analysis of 199 adults with CAH. FH, waist circumference (WC) and QoL were expressed as z-scores adjusted for mid-parental target height (FHTH<...
