Paradoxical severe hypercalcemia is a rare phenomenon observed in some patients in delayed phase following rhabdomyolysis. We present a case of 33-year-old male who developed severe hypercalcemia following successful treatment of rhabdomyolysis. Patient was admitted with agitation and disinhibition, was intubated in A&E due to metabolic acidosis (pH 6.7), hyperkalemia (K+ 7.3 mmol/l), lactic acidosis (23 mmol/l), and pyrexia (40°C). Toxicology screening shown presence...

Introduction: Hypocalcaemia is rare in patients with malignancy, occurring in <2% of patients with malignancy. Osteoblastic bone metastases as an aetiology of hypocalcaemia are further rare.Case description: A 75-year-old male presented to emergency with back pain, and immobility. He was diagnosed to have prostate cancer in 2019. A bone scan in April 2022 showed extensive sclerotic metastases involving axial and prox...

Purpose: To evaluate the added benefit and accuracy of [68Ga]Ga-DOTA-TATE PET/CT scans in detecting pancreatic neuroendocrine tumours, compared to conventional cross-sectional imaging with CT or MRI scans, in patients with multiple endocrine neoplasia type 1 (MEN1)Methods: A retrospective analysis was performed comparing the initial [68Ga]Ga-DOTA-TATE PET/CT to the respective contemporary CT or MRI ...

Introduction: Selective transsphenoidal microadenomectomy (TSS) is the first-line treatment of paediatric Cushing’s disease (CD). Corticotroph adenomas in children are often small and difficult to visualize. We aimed to assess the utility of pituitary MRI and bilateral inferior petrosal sinus sampling (BIPSS) in confirming the diagnosis of CD and the localisation of the adenoma. We also report our early experience of STEALTH MRI (volumetric T1 weighted, contrast-enhanced ...

We report a retrospective, single centre observational study to determine the characteristics and outcomes of pancreatic insulinoma. Interrogation of the Oxford NET database, a departmental database of new NET MDT referrals since 2011 (n = 1059), revealed 23/1059 (2.1%) patients with insulinoma diagnosed and treated between 2011 and 2018. Patient records were reviewed and data was captured on demographics, presentation, investigations, treatments and outcomes: 15/23 (...

Neuroendocrine tumours (NETs) presenting as metastatic cancer of unknown primary site (CUP) are suspected to confer poorer prognosis compared to metastatic NETs of known primary site. We performed a retrospective, single centre study to determine the prognostic indicators in CUP-NETs compared to metastatic small intestinal NET (SiNET), before and after adjusting for factors known to affect overall survival. Subjects were selected from a departmental database of 1050 NET patien...

Introduction: Despite the significant risk of regrowth of non-functioning pituitary adenomas (NFAs) after primary treatment, systematic data on the probability of further tumour progression and the effectiveness of management approaches are lacking.Aims: Assess the probability of further regrowth(s), predictive factors and outcomes of management approaches in patients with NFA diagnosed with adenoma regrowth after primary treatment (surgery combined or n...

Pancreatic neuroendocrine tumours (NETs) are reported to show frequent mutations in chromatin remodelling genes, while pituitary NETS have alterations in histone modification. Histone modifications, and specifically acetylated residues on histone tails are recognised by members of the bromo and extra terminal (BET) protein family, via their bromodomains, causing alterations in the transcription of growth stimulating genes. BET bromodomain inhibitors have been demonstrated to s...

Introduction: Adrenocortical carcinoma (ACC) has a poor prognosis and limited therapeutic options. The epidermal growth factor receptor (EGFR) expression was found to be a good discriminator between malignant and benign adrenal tumours, but was mutated only in 3–10% of ACC cases.Aim: The aim of this study was to assess the effect of inhibition of EGFR with targeted therapies, i.e. Erlotinib (with and without EGF stimulation) on ACC cell proliferatio...

Background: In patients with phaeochromocytoma, sudden and/or chronic exposure to catecholamines may predispose to cardiac pathology, including left ventricular (LV) hypertrophy, myocardial infarction, stress-induced cardiomyopathy and heart failure. We conducted the first prospective, multicentre study using cardiovascular magnetic resonance (CMR) imaging to describe the variety and incidence of cardiac abnormalities in phaeochromocytoma.Methods: Fifty ...
