Ghrelin is a 28 amino acid n-octanoylated peptide which is the natural agonist for the growth hormone secretagogue receptor and which potently stimulates GH release in vivo (1). We studied the effects of a somatostatin infusion on Ghrelin release in normal subjects.STUDY PROTOCOLFour females and five males, 25-40 years of age, body mass index < 28 kg per m2 were studied. Local ethics committee permission was obtained for ...

X-linked recessive hypoparathyroidism (XLHPT), due to congenital parathyroid agenesis, has been reported in two related kindreds from Missouri, USA. Affected individuals, who are males, suffer from epilepsy due to hypocalcaemia during infancy, whilst the females are normocalcaemic. Studies have mapped XLHPT to chromosome Xq27 and defined a 1.5 Mbp interval flanked centromerically by Factor IX and telomerically by DXS984. DNA sequence analysis of 4 candidate genes (proto-dbl, A...

Background: Over 90% of the blood supply to the adenohypophysis arises from hypothalamic portal vessels, in contrast to the systemic blood supply to the posterior lobe. A pre-existing, or tumour stimulated direct (non-portal) blood supply has been suggested as a possible pathogenic mechanism for prolactinoma development.Methods: 6 patients (3 microprolactinomas (mic), and 3 macroprolactinomas (mac)), and one control subject were imaged using a 3T magnet...

We examined the results of treatment of adult Cushing's disease by transphenoidal surgery by a single neurosurgeon (MP). Patients with Nelson's syndrome and those who previously had received treatment for Cushing's by a different surgeon were excluded. We reviewed the pituitary database and patient records for all patients operated between 1988 and 2000 with clear pre-operative evidence of Cushing's disease. 117 patients had clear evidence of a pituitary source of excess ACTH....

BackgroundAlthough anemia was previously described as a complication of diabetes mellitus (DM), it’s prevalence and prognostic meaning in patients with DM and pre-DM with normal kidney function was not thoroughly investigated.MethodsA retrospective analysis of patients with DM and pre-DM referred to the endocrine institute in Meir medical center during 2015. Patients with estimated glomerular filtration ...

Introduction: Liquid biopsies have revolutionised cancer care, from accurate diagnosis to guiding treatment and surveillance. Here, we used shallow Whole Genome Sequencing (sWGS); a cost-effective and easy-to-perform test to explore concordance of copy number alterations (CNAs) between formalin-fixed paraffin-embedded (FFPE) tissue extracted DNA and circulating cell-free DNA (cfDNA) in patients with Thyroid Cancer (TC) during different stages of the disease. <...

Case 1: A 57-year-old lady referred to the Endocrinology department due to a CT Abdomen, performed for abdominal pain, reporting the presence of an incidental left adrenal adenoma. Imaging was reviewed in the Adrenal MDT meeting and further CT Abdomen arranged. Images were reviewed before and after oral contrast. Pre-contrast images revealed a small volume of high-density material within a rounded structure in the left upper quadrant, immediately superior to t...

Introduction: Glucagon-like peptide-1(GLP-1) agonists are widely used for treatment of type 2 diabetes(T2D). To date a number of reports have described improvements in glucose control with the addition of a GLP-1 agonist to the insulin regime in treatment of type 1 diabetes(T1D). From a physiological perspective there is credence to the notion that a GLP-1 agonist will lower glucose levels in people with T1D as they do in T2D. GLP-1 is an endogenous hormone th...

Introduction: 48,XYYY is a rare condition where two extra Y chromosomes alter the neurological, skeletal and reproductive development of the affected individual. Clinical features are usually subtle and the diagnosis is not suspected until fertility issues arise. Here, were report an adult patient with 48,XYYY in the Endocrinology Clinic.Case report: A 24-year-old male was referred to UHL Endocrinology Clinic following i...
