Successful surgery for pancreatic neuro-endocrine tumours (NET) requires accurate tumour localisation. Interpretation of cross-sectional imaging is often difficult, particularly after pancreatic surgery. Imaging by somatostatin-receptor-scintigraphy with indium-labelled octreotide may be useful in identifying recurrent disease; however, octreotide scans may be negative in some pancreatic NET, due to a low level of expression of somatostatin receptors. The GLP-1 receptor is abu...

The outcome of parathyroid surgery is often not clear for at least 24 hours after an operation. Frozen section is not always helpful in distinguishing between adenoma and hyperplasia. Minimally invasive surgical techniques are being refined so the need for perioperative assurance about the effects of surgery has increased. PTH assays have been adapted to give results in less than 20 minutes. We have tested the value of intraoperative PTH measurements in 10 surgical cases under...

Introduction: Histology is a poor predictor of the malignant potential of phaeochromocytomas and paragangliomas (PPGL) and only the presence of distant metastasis confirms malignancy. This study reviews patterns of recurrence, treatment and mortality in patients with malignant PPGL presenting to our department at UCLH over 30 years.Materials and Methods: In our series of 128 patients with PPGL, 26 (20%) with maligna...

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: Gigantism is a rare condition with accelerated growth in childhood when the epiphyseal plates are not fused. Most cases are due to growth hormone (GH) secretion from a pituitary adenoma. Rarer causes of GH-related gigantism include somatotroph hyperplasia as part of McCune-Albright syndrome, Carney complex, X-linked acrogigantism or ectopic GHRH production.Case presentation: An 18-year-old male with c.249_252delGTCT;p.I85Sfs MEN1 mut...

Introduction: Sestamibi (SM) and ultrasound (US) are routinely used for preoperative localisation of abnormal parathyroids in patients with hyperparathyroidism. Minimally invasive parathyroidectomy (MIP) is recommended if localisation is concordant, otherwise neck exploration is the method of choice.Aim: To assess whether introduction of intraoperative parathormone (IOPTH) monitoring allows us to perform MIP successfully in patients with non concordant f...

A 25-year-old pregnant lady presented to the accident and emergency department at 16 weeks gestation with intractable vomiting, weight loss and lethargy. She reported a 2 months history of hyperemesis gravidarum managed in the community prior to admission.She had no past medical history and her only medication was of a Polish antenatal vitamin containing 400 IU of Vitamin D (D2). Her blood biochemistry revealed a markedly raised corrected calcium at 3.57...

Familial Hypocalcuric Hypercalcaemia (FHH) is an autosomal dominant condition associated with inactivating mutations of the human calcium sensing receptor (CaSR) gene (heterozygotes). Neonatal Severe Primary Hyperparathyroidism (NSHPT) affects infants who inherit two such inactivating copies (homozygotes). NSHPT is frequently fatal without parathyroidectomy (PTx).Between 1984 and 2003 we have diagnosed and treated seven children (4M, 3F) with NSHPT. All ...

Background: Primary hyperparathyroidism (PHPT) is a common endocrine disorder. Aim of this audit was to assess clinical, biochemical parameters, localisation modalities and outcome in patients undergoing parathyroidectomy at University College London Hospital (UCLH).Methods: We audited all patients aged 15-years or above, undergoing parathyroidectomy, from 01-02-2018 to 31-12-2021 at UCLH via retrospective data collectio...
