Giant Cell Arteritis (GCA) is a systemic vasculitis of the medium and large sized vessels with a tendency to involve extracranial branches of the carotid arteries.
Criteria
The APACHE II Severity of Disease Classification System
APACHE II uses a point score based upon initial values of 12 routine physiologic measurements, age, and previous health status to provide a general measure of severity of disease.
ROME II Diagnostic Criteria for Functional Disorders of the Anus and Rectum
The diagnosis of a Functional Disorder of the Anus and Rectum always presumes the absence of a structural or biochemical explanation for the symptoms.
F1. Functional Fecal Incontinence
Recurrent uncontrolled passage of fecal material for at least one month, in an individual with a developmental age of at least 4 years, associated with:
- Fecal impaction; or
- Diarrhea; or
- Nonstructural anal sphincter dysfunction.
Criteria for the Classification of the Antiphospholipid Syndrome (APS)
Clinical Criteria
Vascular thrombosis
- One or more clinical episodes of arterial, venous, or small-vessel thrombosis, occurring within any tissue or organ
DSM-IV Diagnostic Criteria for Anorexia Nervosa
A. Refusal to maintain body weight at or above a minimally normal weight for age and height (e.g., weight loss leading to maintenance of body weight less than 85% of that expected; or failure to make expected weight gain during period of growth, leading to body weight less than 85% of that expected).
B. Intense fear of gaining weight or becoming fat, even though underweight.
Braunwald Classification of Unstable Angina (UA)
A classification has been proposed by Braunwald to facilitate the assignation of patients to a particular risk group. This classification takes into account the severity of symptoms, the clinical circumstances surrounding the anginal episode, and the intensity of treatment.
1993 Revised Classification System for HIV Infection and Expanded AIDS Surveillance Case Definition for Adolescents and Adults
CDC has revised the classification system for HIV infection to emphasize the clinical importance of the CD4+ T-lymphocyte count in the categorization of HIV-related clinical conditions.
Criteria for Chronic Stable Refractory Angina
The criteria for chronic stable refractory angina were defined by Mannheimer and colleagues in 2002 as a chronic condition characterized by the presence of angina caused by coronary insufficiency in the presence of coronary artery disease which cannot be controlled by a combination of medical therapy, angioplasty and coronary bypass surgery. The presence of reversible myocardial ischemia should be clinically established to be the cause of the symptoms. Chronic is defined as a duration of more than 3 months.
Classification and Severity of Angina
Class I
No angina with ordinary physical activity (e.g., walking, climbing stairs). Angina with strenuous or prolonged exertion.
Class II
Early-onset limitation of ordinary activity (e.g., walking rapidly or walking >2 blocks; climbing stairs rapidly or climbing >1 flight); angina may be worse after meals, in cold temperatures, or with emotional stress.
Serum Levels That Differentiate Anemia of Chronic Disease from Iron-Deficiency Anemia
Iron deficiency anemia develops when body stores of iron drop too low to support normal red blood cell (RBC) production. Inadequate dietary iron, impaired iron absorption, bleeding, or loss of body iron in the urine may be the cause.
