Behçet syndrome, also known as Behçet disease, is characterized by recurrent oral aphthae and any of several systemic manifestations including genital aphthae, ocular disease, skin lesions, gastrointestinal involvement, neurologic disease, vascular disease, or arthritis.
Criteria
Common Diagnostic Criteria for Left and Right Atrial Abnormalities
Left Atrial Abnormality
- Prolonged P wave duration of >120 msec in lead II
- Prominent notching of the P wave, usually most obvious in lead II, with an interval between the notches of >40 msec (p mitrale)
- Ratio between the duration of the P wave in lead II and the duration of the PR segment of >1.6
- Increased duration and depth of the terminal negative portion of the P wave in lead V1 (the P terminal force) so that the area subtended by it exceeds 0.04 mm-sec (Morris index)
- Leftward shift of the mean P wave axis to between -30 and +45 degrees
Revised ARA Criteria for the Classification of Rheumatoid Arthritis (RA)
For classification purposes, a patient is said to have RA if he or she has satisfied at least 4 of the following 7 criteria. Criteria 1 through 4 must have been present for at least 6 weeks. Patients with 2 clinical diagnoses are not excluded. Designation as classic, definite, or probable RA is not to be made.
Revised Criteria for the Classification of Giant-Cell Arteritis (GCA)
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.
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.
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.
El Escorial Criteria for the Diagnosis of Amyotrophic Lateral Sclerosis (ALS)
The diagnosis of Amyotrophic Lateral Sclerosis (ALS) requires
A. the presence of:
(A:1) evidence of lower motor neuron (LMN) degeneration by clinical, electrophysiological or neuropathologic examination,
(A:2) evidence of upper motor neuron (UMN) degeneration by clinical examination, and
(A:3) progressive spread of symptoms or signs within a region or to other regions, as determined by history or examination, together with
