BACKGROUND Previous research in patients with anorexia nervosa showed heightened brain response during a taste reward conditioning task and heightened sensitivity to rewarding and punishing stimuli. Here we tested the hypothesis that individuals recovered from anorexia nervosa would also experience greater brain activation during this task as well as higher sensitivity to salient stimuli than c...

a serum phosphorus if ATPase enzyme is available. Maintenance plasma levels range between 10 and 40 m,ug/ml with a mean value of 25 mrjug/ml. There is overlapping of maintenance and toxic serum levels in the higher ranges. Values over 45 m,ug/ml warrant careful evaluation for digitalis intoxication. Maintenance plasma levels can be achieved with or without the usual digitalizing dosage if time ...

For many years it has been suggested that considerable quantities of digitalis bodies accumulate in edema fluid, that rapid diuresis with mercurial diuretic drugs "liberates" these glycosides into the blood stream as the edema fluids are mobilized and excreted by the kidneys, and that the ensuing "redigitalization" may lead to manifestations of digitalis toxicity in the already adequately digit...

When Policy Topic is covered A number of indications for chelation therapy have received Food and Drug Administration (FDA) approval and for which chelation therapy is considered standard of care treatment. They include:  extreme conditions of metal toxicity;  treatment of chronic iron overload due to blood transfusions (transfusional hemosiderosis) and due to non-transfusion-dependent thalas...

Electrode catheter recordings of the bundle of His (H), the right bundle branch (RB) and the left bundle branch (LB) were obtained in 15 dogs without thoracotomy during sinus rhythm and digitalis-induced ventricular tachycardia. During sinus rhythm an H-RB-LB sequence was recorded. This sequence was unchanged during atrial stimulation at rapid rates or during cardiac slowing by vagal stimulatio...

Anorexia nervosa is a primary behavioural disorder characterised by a disturbed sense of body image, a morbid fear of gaining weight, disturbed eating pattern, marked weight loss and amenorrhea. It usually affects adolescent women (95%).1 Medical complications of anorexia nervosa can involve all organic systems of the body.2'3 A rare complication is spontaneous pneumomediastinum, with only a fe...

Eating disorders, including anorexia nervosa, bulimia nervosa, binge-eating disorder, and atypical eating disorder (eating disorder not otherwise specified or NOS), are estimated to occur in 5-10 million young and adult women and one million males in the United States. The etiology of eating disorders is complex and appears to include predisposing genetic factors and serotonin dysregulation, as...

Experiments were performed in anesthetized dogs to study some effects of propranolol, dextro-propranolol and ICI50,172 on digitalis-induced arrhythmias and digitalis-induced sensitization to electrical shock. When given in beta-blocking doses, propranolol did not abbreviate ouabain-induced ventricular tachycardia (VT) or decrease ouabain-induced sensitization to electrical shock. In larger dose...

Digitalis intoxication is a common and potentially life-threatening situation [1]. In this condition, the administration of digoxin-specific antibodies (Fab) have proven to be effective in controlling serious complications [2]. However, in patients with severe renal impairment, the clearance of Fab–digoxin complexes is compromised, and this may reduce the utility of Fab therapy in those conditi...

According to International Classification of Diseases by World Health Organization, eating disorders are behavioural syndromes associated with physiological disturbances [1]. Eating disorders include anorexia nervosa, atypical anorexia nervosa, bulimia nervosa, atypical bulimia nervosa, overeating associated with other psychological disturbances and vomiting associated with other psychological ...
