A 17-year-old female was referred to the adult endocrine clinic with a history of primary amenorrhoea. She was short in stature with a height below the 4th centile for her age. Her BMI was 24 kg/m2 with a weight below the 25th centile and there was delay in bone-age 2 years.She had an interesting past medical history of late-onset central nocturnal hypoventilation from the age of 8 years when she presented with apnoeic episodes and weight gain...

Mithun (Bos frontalis), a free-range domesticated ungulate, reared primarily for beef and occasionally for milk, is mainly distributed in the South-East Asia. Much scientific reports on reproductive-endocrinology in this species are not available at present. The current study was designed to standardise and validate a simple, sensitive and direct enzymeimmunoassay (EIA) on microtitre plates using second antibody coating technique to determine 13,14-dihydro-15-keto PGF<s...

Anabolic steroids enhance performance in atheletes, but can lead to life threatening consequences. We report a 33-year-old male amateur body-builder using anabolic steroids, presenting with acute inferolateral myocardial infraction and marked hyperlipidaemia. He had no known cardiovascular risk factors. Despite rapid thrombolysis, peak creatinine kinase was 3,348 iu/l, signifying significant myocardial damage and a markedly raised total cholesterol of 10.6 mmol/l, with a low H...

Carcinoid tumours are the most common neuroendocrine tumors with an estimated incidence of 7-13/ million population. The clinical symptoms of carcinoid tumours usually relate to presence of the carcinoid syndrome, local symptoms or metastases. Most are asymptomatic with only 10% manifesting the 'carcinoid syndrome'. We report an 86 year-old lady referred for evaluation of multiple subcutaneous, nodules around her neck and upper back, with a suspicion of underlying lymphoprolif...

Background: Mutation in the CYP24A1 gene can have variable phenotypes including infantile hypercalcemia and adult-onset hypercalcemia, hypercalciuria, nephrocalcinosis, or nephrolithiasis. CYP24A1 gene mutation is a rare but important cause of PTH-independent hypercalcemia.Case Presentation: We describe a case of a 67-year-old gentleman who presented with lethargy, fatigue and weight loss. He was found to have PTH-indepe...

Background: Hydrocortisone day curves (HCDCs) are commonly used to assess hydrocortisone replacement for patients with adrenal insufficiency (AI).Methods: HCDCs were obtained for 216 adrenally insufficient patients between 2004 and 2012 at Imperial College Healthcare NHS Trust. The area under the curve (AUC) was calculated for each patient’s day profile. Lipid profiles and glycated haemoglobin (HbA1c) values were recorded for each patient at both th...

Background: Glucocorticoid-induced osteoporosis is one of the major clinical concerns of long-term steroid treatment. Previous studies have shown that immunosuppressive doses of glucocorticoid can lead to osteoporosis. This study investigated whether there is a relationship between cortisol exposure and the development of osteoporosis in patients receiving replacement doses.Methods: Hydrocortisone day curves (HCDCs) performed a...
