Background: Pancreatic neuroendocrine tumours (pNETs) are commonly reported in patients with MEN1. The estimated incidence is reported as 40–80% of adults with MEN1 and pNETs are frequently multifocal. Guidelines recommend that CT, MRI and endoscopic ultrasound (EUS) can be used for detection and surveillance of pNETs in MEN1. MRI has been the most commonly used modality, but EUS may be more sensitive in detecting pNETs.Objective: To compare the sen...

Background: Self-management is essential for patients with adrenal insufficiency (AI) to achieve optimal outcomes of glucocorticoid (GC) replacement therapy by minimising adverse effects from over- or under-replacement and appropriately adjusting the dose in intercurrent illness to prevent adrenal crisis. Evidence suggests that many patients report deficits in self-management especially concerning ‘sick day rules’, prevention and management of adrenal crisis and have...

Background: There is no consensus on the optimal timing of surgery for primary hyperparathyroidism (PHPT) in MEN1. Experienced centres recommend subtotal or total parathyroid surgery with three and a half gland surgery along with thymic removal as a favoured procedure; but long-term outcomes have rarely been reported.Objective: To investigate the indications and outcomes for surgery in patients with PHPT in MEN1Methods: Review of c...

Germline mutations account for hereditary phaeochromocytoma (PCC) and paraganglioma (PGL) syndromes. SDHB immunostaining can be used to functionally characterise SDH status on PCC and PGL tumours. Genetic testing of multiple candidate genes is increasingly performed in patients presenting with PCC/PGL tumours. We investigated the effectiveness of SDHB immunostaining as an initial screening tool in identifying SDH mutations.This was a retrospecti...

Performing water deprivation test (WDT) and prolonged water deprivation test (PWDT) is some of the roles undertaken by endocrine nurse in specialist endocrine units. These tests need to be done in a safe and control environment.Objectives: To provide safe information to patients to avoid fluids overload when they arrive for the tests. Can the specialist endocrine nurse make clinical decision to terminate the test base on clinical evidence and at what poi...

The pulsatile release of GnRH regulates the synthesis and secretion of pituitary FSH and LH. Two transcription factors, the cAMP response element binding protein (CREB) and inducible cAMP early repressor (ICER), have been implicated in the regulation of rat FSHβ gene expression. We hypothesized that CREB and ICER are activated by distinct signaling pathways in response to pulsatile GnRH to modulate FSHβ gene expression, which is preferentially stimulated at low (ever...

Background: Testosterone replacement is the mainstay of treatment for male hypogonadism. The most commonly reported adverse event in testosterone trials is polycythaemia. This study assessed the prevalence of polycythaemia in males receiving testosterone replacement and compared prevalence rates between different treatment preparations.Methods: 216 men were included in this retrospective observational study conducted from January 2009 to December 2012. 1...

Background: Bardet Biedl syndrome (BBS) is a rare autosomal recessive disorder caused by ciliary dysfunction. It is characterised by rod cone dystrophy, polydactyly, renal dysfunction, cognitive impairment. Endocrine consequences are thought to include hypogonadism, obesity and polyuria. However little is known about the endocrine and metabolic abnormalities in adult patients.Methods: One hundred and fifty-four patients with BBS were identified through t...

Aim: To investigate the glycaemic control of patients with T1DM before and after the introduction of CSII therapy.Methods: All patients with T1DM receiving CSII therapy for more than 6 months attending the Children’s University Hospital from 2005–2011 were included. Glycosylated haemoglobin (HbA1c) was recorded 12 and 6 months prior to starting therapy, at the time of CSII initiation and annually thereafter. Adverse events and BMI were also rec...

Background: The route of oestrogen replacement has an influence on GH sensitivity in hypopituitary women, although the practical relevance of this effect remains unclear.Objectives: To compare the effects of oral and transdermal oestrogen replacement on GH requirement in adult females with hypopituitarism receiving GH replacement.Methods: This cross-sectional, observational study included 69 GH-deficient women each receiving a stab...
