Introduction: Iodine is important for thyroid hormone synthesis, and iodine deficiency in pregnancy may impair foetal neurological development. Perchlorate, found in some foods and everyday chemicals (e.g. fertilisers) and thiocyanate, which is found in cigarette smoke, decrease the transport of iodine from the circulation to the thyroid cells by inhibiting the sodium-iodide symporter. Environmental exposure to these substances during pregnancy may result in reduced thyroid ho...

Objectives: The aim of the study was to evaluate the normal reference values for thyroid uptake using Technetium-99 m (Tc-99 m) pertechnetate.Methods: Sixty-seven euthyroid patients with primary hyperparathydism who underwent parathyroid imaging with Tc-99 m pertechnetate between January 2012 to April 2014 at the Nuclear Medicine department, Newcastle upon Tyne Hospitals was studied. Electronic medical records and biochemical thyroid functi...

Hyponatremia is the commonest electrolyte abnormality presenting to Medical Admissions and when acute, severe and symptomatic, is associated with high mortality. The syndrome of inappropriate antidiuretic hormone secretion (SIADH) is the most common underlying disorder in hospitalised patients with euvolaemic hyponatraemia and is a complication of many clinical conditions and drug therapies.We discuss the cases of two patients...

Background: We describe a patient with 46XX ovotesticular difference of sex development (DSD) due to 46XX/69XXY gonadal mixoploidy, also an NR5A1 variant, who developed severe early-onset obesity and subsequently a pathogenic MC4R variant was identified.Case Presentation: A term Caucasian baby weighing 3.64kg with non-consanguineous parents presented with atypical genitalia (Prader Stage 2-3) with clitoromegaly, perineal urethral openin...

Background: A quarter of UK children now leave primary school obese. Childhood obesity is associated with significant comorbidity including obstructive sleep apnoea, type 2 diabetes, non-alcoholic fatty liver disease, hypertension and depression. We report our experience of using semaglutide, a weekly subcutaneous GLP1 receptor agonist, as a weight-loss adjunct for severely obese children in combination with dietary and lifestyle support from a multidisciplinary team.<p cl...

Background: Chronic opioid use may lead to adrenal insufficiency (AI) due to suppression of the hypothalamic-pituitary-adrenal axis. We aimed to determine incidence of AI and mortality in patients treated with chronic opioid therapy in a standardized geographically well-defined population.Methods: In this population-based cohort study we assessed the standardized incidence rate of first time met chronic opioid use and adrenal insufficiency in adult resid...

Introduction: 2 to 3% of the causes of hypoglycemia in the population without diabetes mellitus correspond to tumors of cells other than islets. Below is a rare case of hypoglycemia related to a pleural tumor. Clinical case: A 65-year-old woman with arterial hypertension, psychiatric treatment for confusion and behavioral changes of 6 months of evolution, palpitations and night sweats, loss of 20 kg of weight, several admissions to the emergency room, un...
