Aim: Recent studies reported a wide range in baseline and peak cortisol responses to surgery. We report the results of cosyntropin stimulation testing following unilateral adrenalectomy for non-steroid secreting lesions.Methods: Data of 36 patients who underwent cosyntropin stimulation testing on the second day post unilateral adrenalectomy were collected retrospectively. None of the patients had clinical signs of hypercortisolism. No patient received pr...

Introduction: Primary hyperparathyroidism (PHPT) is an endocrine condition in which autonomous excessive secretion of parathyroid hormone (PTH) results in hypercalcaemia. In approximately 80% of cases the aetiology is due to a single parathyroid adenoma, the remainder are due to hyperplasia of more than one gland. Familial Hypocalciuric Hypercalcaemia (FHH) is an autosomal dominant, inactivating mutation of the calcium-sensing receptor, causing a right-shift in the concentrati...

Introduction: Phosphatase and tensin homolog gene (PTEN) gene encodes a lipid phosphatase that plays a central role in cell-cycle processes. PTEN hamartoma tumour syndrome (PHTS), caused by the mutation of the PTEN gene, is a diverse multi-system disorder. PHTS is characterised by the hamartomatous growths, increased risk of breast, thyroid, and renal cancers. In terms of thyroid presentation of PHTS, there is up to 75% risk of multinodular goitre and the life...

Primary hyperparathyroidism is a common endocrine condition; 80% due to a parathyroid adenoma. We present an unusual case of a 69-year old white European female, who presented first in 2012 with mild hypercalcaemia (< 2.8 mmol/l), osteoporosis, hypertension and type 2 diabetes. Pharmacotherapy included Bendroflumethiazide, but no phosphate supplements. Investigations revealed primary hyperparathyroidism and dual-modality scanning showed no evidence of an adenoma, although ...

Adrenocortical carcinoma (ACC) is a rare malignancy with limited treatment options and a heterogenous prognosis. The histological diagnosis of ACC is complex and there is increasing interest in identifying and validating new immunohistochemical markers. Delta-like non-canonical Notch ligand 1 (DLK1) is a cleavable single-pass transmembrane protein. In humans, DLK1 is present in many tissues during foetal development, is restricted to progenitor/stem cells in a few adult tissue...
