BACKGROUND Epidemiologic studies have demonstrated substantial variations in per capita rates of many surgical procedures, including rotator cuff repair. The purpose of the current study was to characterize orthopaedic surgeons' attitudes concerning medical decision-making about rotator cuff surgery and to investigate the associations between these beliefs(More)
The high prevalence of celiac disease in patients with autoimmune hypothyroidism, compared to the general population, has been well documented but screening for celiac disease is not recommended as yet in otherwise asymptomatic hypothyroid patients. In recent years the high prevalence of undiagnosed celiac disease in the general population, largely as a(More)
Hereditary haemochromatosis (HH) is a genetic disorder in which abnormal iron handling leads to excessive iron accumulation in systemic tissues. Magnetic resonance imaging studies suggest excess iron deposition in the basal ganglia of patients with HH. The symptoms of neurological complications of HH include cognitive decline, gait difficulties, cerebellar(More)
BACKGROUND Coeliac disease has an increased prevalence in a number of autoimmune endocrine conditions. An association between coeliac disease and Addison's disease has been proposed in isolated case reports, but has not been formally studied. AIM To investigate the extent of this association. DESIGN Prospective screening of patients with confirmed(More)
Hypogonadism, usually hypogonadotropic in origin, is the most common nondiabetic endocrinopathy in hereditary hemochromatosis (HH). Early studies, usually evaluating small numbers of patients with advanced HH, report prevalence rates of 10-100%. The clinical presentation of HH has changed in recent years as a result of increased awareness and screening. We(More)
BACKGROUND Mathematical and mechanical models of cerebral circulation indicate that the resistance of the collapsed internal jugular veins limits cerebral blood flow during high acceleration (+Gz) and that positive pressure breathing (PPB) restores cerebral blood flow by elevating blood pressure and preventing collapse of the vein. The effect of(More)
Serial measurements of whole body potassium and whole body nitrogen were carried out in 18 newly diagnosed diabetcs. Initial measurements were made before treatment of diabetes was commenced, and further measurements were carried out following the start of treatment. Six patients required insulin and the remainder were treated either with diet alone (four(More)
Fourteen adults in whom diabetes mellitus and coeliac disease coexist, are described. In no patient was coeliac disease diagnosed (biopsy proven) before the age of 28 years. Diabetes was recognized before coeliac disease in all except one. Diabetic control was very unstable and hypoglycaemia particularly troublesome before treatment with a gluten free diet.(More)
