Bipolar disorder, a medical illness with substantial morbidity and mortality, is characterized by episodic recurrent mania or hypomania and major depression. The hallmark of bipolar disorder is at least one episode of mania (bipolar I disorder) or hypomania (bipolar II disorder).
Criteria
Diagnostic Criteria for Major Depression
In major depression, the person’s mood is described as depressed, sad, hopeless, discouraged, or “down in the dumps”.
The 2010 American College of Rheumatology/European League Against Rheumatism classification Criteria for Rheumatoid Arthritis (RA)
Rheumatoid arthritis (RA) is a chronic inflammatory disease characterized by joint swelling, joint tenderness, and destruction of synovial joints, leading to severe disability and premature mortality. Given the presence of autoantibodies, such as rheumatoid factor (RF) and anti–citrullinated protein antibody (ACPA) (tested as anti–cyclic citrullinated peptide [anti-CCP]), which can precede the clinical manifestation of RA by many years, RA is considered an autoimmune disease.
A joint working group of the ACR and the European League Against Rheumatism (EULAR) was therefore formed to develop a new approach for classification of RA.
Diagnostic Criteria for Transverse Myelitis
The term “transverse myelitis” describes a heterogeneous group of inflammatory disorders that are characterized by acute or subacute motor, sensory, and autonomic (bladder, bowel, and sexual) spinal cord dysfunction. The clinical signs are caused by an interruption in ascending and descending neuroanatomical pathways in the transverse plane of the spinal cord, and a resulting sensory level is characteristic of the syndrome.
Diagnostic Criteria for Complex Regional Pain Syndrome (CRPS)
Complex regional pain syndrome (CRPS) has been known by many names, but most commonly as reflex sympathetic dystrophy and causalgia (as attributed to Evans and Mitchell, respectively). In the past, it was diagnosed using a variety of nonstandardized and idiosyncratic diagnostic systems. The name was ultimately changed to complex regional pain syndrome (CRPS) at a consensus workshop in Orlando, Florida, in 1994, with the new name and diagnostic criteria codified by the International Association for the Study of Pain (IASP) task force on taxonomy.
Criterios de Clasificación de Dermatomiositis y Polimiositis
La dermatomiositis es una enfermedad idiopática, que incluye miopatía inflamatoria y manifestaciones cutáneas características; la polimiositis incluye la miopatía inflamatoria sin signos cutáneos.
Diagnosis of Obstructive Sleep Apnea (OSA) in Adults and Children
Obstructive sleep apnea syndrome (OSAS) is defined as repeated episodes of obstructive apneas and hypopneas during sleep, frequently followed by transient hemoglobin desaturation (hypoxemia) and unconscious (EEG) arousals.
Diagnostic Criteria for Progressive Multifocal Leukoencephalopathy (PML)
Progressive multifocal leukoencephalopathy (PML) is a demyelinating disease of the central nervous system caused by the reactivation of a ubiquitous polyomavirus JC (JCV). PML was for many years a rare disease occurring only in patients with underlying severe impaired immunity.
Diagnostic Criteria for Sporadic Creutzfeldt-Jakob Disease (sCJD)
Classic Creutzfeldt-Jakob Disease (CJD) is a human prion disease. It is a neurodegenerative disorder with characteristic clinical and diagnostic features. This disease is rapidly progressive and always fatal. Infection with this disease leads to death, usually within 1 year of onset of illness. The criteria for clinical diagnosis plus the CSF real-time quaking-induced conversion (RT-QuIC) accurately identifies patients with sCJD (sensitivity 97%, specificity 99%).
Electrodiagnostic Criteria for Chronic Inflammatory Demyelinating Polyradiculoneuropathy (CIDP)
These criteria are applied by testing the median, ulnar (stimulated below the elbow), peroneal (stimulated below the fibular head), and tibial nerves on one side of the body. During testing, limb temperature should be no less than 33°C at the palm and no less than 30°C at the external malleolus.
