It can be used to detect abnormalities such as those associated with pituitary tumors. Thyroid function tests: tests used to assess thyroid functioning by checking levels of thyroid-stimulating hormone (TSH), thyroxine (T4), and triiodothyronine (T3). Differential diagnoses
A variety of medical and psychological conditions have been misdiagnosed as anorexia nervosa; in some cases the correct diagnosis was not made for more than ten years. The distinction between binge purging anorexia, bulimia nervosa and Other Specified Feeding or Eating Disorders (OSFED) is often difficult for non-specialist clinicians. A main factor differentiating binge-purge anorexia from bulimia is the gap in physical weight. Patients with bulimia nervosa are ordinarily at a healthy weight, or slightly overweight. Patients with binge-purge anorexia are commonly underweight. Moreover, patients with the binge-purging subtype may be significantly underweight and typically do not binge-eat large amounts of food. In contrast, those with bulimia nervosa tend to binge large amounts of food. It is not unusual for patients with an eating disorder to "move through" various diagnoses as their behavior and beliefs change over time. Treatment
There is no conclusive evidence that any particular treatment for anorexia nervosa works better than others.Treatment for anorexia nervosa tries to address three main areas. Restoring the person to a healthy weight;
Treating the psychological disorders related to the illness;
Reducing or eliminating behaviors or thoughts that originally led to the disordered eating.In some clinical settings a specific body image intervention is performed to reduce body dissatisfaction and body image disturbance.
Acute zonal occult outer retinopathy (AZOOR) is an inflammatory retinopathy in the category of white dot syndromes typified by acute loss of one or more zones of outer retinal function associated with photopsia, minimal funduscopic changes and abnormal electroretinography findings.This retinal disease was first described by Donald Gass in 1992. Relatively little is known about the condition. Risk factors
Caucasian females in their mid-thirties appear to be most susceptible but the disease may affect anyone regardless of age, sex or race. Pathophysiology
The disease mechanism is unknown but it is believed that it may be caused by a virus, or an auto immune response. References
