Medullary thyroid cancer (MTC) accounts for 5–10% of all thyroid cancers and can be either sporadic (75%) or familial (25%). Familial MTC is associated with hereditary syndromes such as Multiple Endocrine Neoplasia (MEN) type 2A or 2B and Familial Medullary Thyroid Cancer (FMTC). Sporadic MTC most often present as thyroid nodule and fine needle aspiration cytology combined with elevated plasma calcitonin levels is diagnostic in about 90% of cases. Hereditary forms of MTC ...

Introduction: Correlation of papillary thyroid cancer and lymphocytic thyroiditis is well documented but the incidence of thyroid malignancies in Graves’ disease especially in the absence of nodular thyroid disease is considered to be uncommon.Method: We conducted a retrospective audit of forty-four patients with established diagnosis of Grave’s thyrotoxicosis treated with total thyroidectomy from 2010-2013 (36 months), in a tertiary care centr...

Case: A 50-years-old gentleman underwent cardiac surgery which was complicated by postoperative arrythmias and ischemic stroke. He was found to have raised calcium of 2.9 (2.2–2.6 mmol/l) subsequent to which PTH was tested and found to be raised at 34.2 (1.6–6.9 pmol/l) which increased to 41.2 pmol/l in few days. He was referred for work up and management of primary hyperparathyroidism. An USS of the neck showed 1.5 cm nodule posterior to left thyroid lobe and Sestim...

Background: Patients with hypoparathyroidism require frequent calcium measurements and currently there is no point of care device allowing this to be done at home by patients themselves. The aim of our study was to evaluate whether ionized calcium(iCa) can be accurately measured in venous and capillary blood and saliva by a repurposed device LAQUA.(R&D Ref 18/0058– IRAS 236079)Methods: Patients undergoing thyroid and parathyroid surgery underwen...

Introduction: PHPT is reported to be rare in pregnancy, with 150 cases described in the literature. Its incidence is 8/100 000 in childbearing women/year. PHPT may lead to a loss of up to 50% of pregnancies through miscarriage or stillbirth, dehydration, hyperemesis, nephrolithiasis, pre-eclampsia, fractures and pancreatitis in mothers; and death, hypocalcaemia and tetany in neonates. Intrauterine growth retardation, low birth weight and pre-term labour were described. Rate of...

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...

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...
