The optimum approach to long-term follow-up of well differentiated thyroid cancer (DTC) remains unclear. We assessed the outcome of DTC patients followed in primary care (PrC) from Edmonton, AB with tertiary care (TrC) settings from Halifax, NS and London, ON. Patients who met the following criteria were identified: a) Initial diagnosis between January 1, 2006 to December 31, 2011, b) primary tumourA total of 317 patients, (PrC=93 and TrC=2...

Background: Studies suggest that glucocorticoid hypersecretion alongside primary hyperaldosteronism (PA) is common and may contribute to the adverse metabolic phenotype. Adrenal crisis post-surgery for PA is rare.Aim: To determine the prevalence of cortisol co-secretion in PA in patients at Imperial College London NHS Trust, Hammersmith Hospital (a tertiary referral centre for adrenal tumours).Methods: Am...

Background: Characterisation of large adrenal lesion is challenging. There is no single robust imaging marker in defining benignity, especially for lesions which are greater than 4cm and are believed to carry increased risk of malignancy.A radiolabelled cholesterol analog tracer, I-131-Norcholesterol (NP-59), localises to adrenal cortical lesions. It has an established role in Conn’s syndrome. It is not expected to concent...

Background: Phaeochromocytomas (PCC) and paragangliomas (PGL) are tumours derived from neural crest cells within the adrenal medulla or extra-adrenal ganglia, respectively. Over 20 known genes are implicated in at least 30% of cases. Experience with these tumours in individual centres is limited due to their rarity.Objective: To describe the demographics, genetics, treatment and progression-free survival (PFS) in ...

Very early in the Covid-19 pandemic it became clear that diabetes was a highly significant comorbidity with an increased risk of mortality in adults of up to 3.5 fold. At the same time, anecdotes started to circulate of an apparent unseasonal increase in incidence and severity of DKA in children and young people presenting with type 1 diabetes [T1DM]. In order to examine this further, the characteristics of children presenting with T1DM from January to July 2020 in North East ...

We work in a service at UCLH in London which cares for young people and adults with differences of sex development. Among other diagnoses CAH makes up quite a lot of our cohort of patients. Adolescents with CAH that our team see include those born with atypical genitalia who may have had, or have not had surgery in childhood on their clitoris or vagina. We also see adolescents with CAH who have issues with puberty and their periods. For adolescents with issues with their genit...

Central precocious puberty (CPP) is a common and well-recognised condition characterised by premature activation of the hypothalamic-pituitary-gonadal axis, with consequent potential adverse health and psychosocial outcomes. Standard management of CPP is with periodic injections of gonadotropin-releasing hormone analogue therapy. Decapeptyl SR (Triptorelin pamoate) has for several years been available as a long-acting (12-weekly, 11.25 mg) preparation, but more recently is ava...

Introduction: Primary hyperparathyroidism is a common endocrine disorder, surgery is curative. Patients with severe hypercalcemia receive cinacalcet or intravenous bisphosphonates as bridging. Intra-operative-parathyroid-hormone (IOPTH) measurement improves surgical accuracy. Bisphosphonates may increase PTH, while cinacalcet reduces it. The main aim was to assess the effect of zoledronate and cinacalcet on IOPTH.Method: Patients over 15-yo who underwent...

Background: Hypercalcaemia is common in renal transplant recipients, the majority of whom have PTH-dependent hypercalcaemia due to tertiary hyperparathyroidism. PTH-independent hypercalcaemia is less common and is associated with significant, treatable underlying pathologies. In this study, we aimed to evaluate the prevalence and aetiology of PTH-independent hypercalcaemia in post-renal transplant patients.Method: This was a retrospective, single-centre ...
