Patients with Cushing's disease are well known to develop easy bruising due to cortisol excess but are also predisposed to thrombembolism.We present four patients who developed thromboembolism during active Cushing's disease.Case 1- Four year history of hypertension, osteoporosis and central obesity. A DVT developed prior to referral. Initial urinary free cortisol(UFC)was 524nmol/24hrs. Inferior petrosal sinus sampling indicated ...

Introduction Some published studies suggest acromegalic patients have an increased risk of colonic tumours or pre-malignant dysplastic polyps. We assessed the prevalence of colonic polyps in Oxford acromegalic patients.Methods Patient database identified all 80 acromegalic patients who had had a colonoscopy.Control Patients Our data and published data on two autopsy and eight colonoscopic screening studies in asymptomatic non-acrom...

To identify genes causing hypercalciuria, we screened male offspring of C57BL/6J male mice mutagenised by N-ethyl-N-nitrosourea (ENU) for this abnormality. Mice were kept in accordance with UK Home Office welfare guidelines and project licence restrictions. Metabolic cage studies were performed to collect 24-hour urine samples, and this revealed one mouse with hypercalciuria (Hcalc1). Inheritance testing demonstrated that Hcalc1 was inherited as an autosomal domi...

BACKGROUD: Parathyroid hormone (PTH) is normally secreted in a circadian rhythm and modulates bone turnover through the differential stimulation of receptor activator for nuclear factor kappa-B ligand (RANKL) and suppression of osteoprotegerin (OPG), both of which are fundamental factors in regulating bone turnover. We have studied the relationship between PTH and OPG over a 24-hour period.METHODS: Hourly peripheral venous blood samples were obtained fro...
