Encephalitis is a severe inflammatory disorder of the brain with many possible causes and a complex differential diagnosis.
Criteria
Revised Sapporo Criteria for Antiphospholipid Syndrome (APS)
Antiphospholipid antibody syndrome (APS) is an autoimmune disorder characterized by vascular thrombosis, complications during pregnancy, and the presence of antiphospholipid antibodies (APL) in plasma.
Diagnostic Criteria for Primary Myelofibrosis (PMF)
Primary myelofibrosis (PMF) is a myeloproliferative neoplasm (MPN) characterized by stem cell-derived clonal myeloproliferation that is often but not always accompanied by JAK2, CALR or MPL mutation, abnormal cytokine expression, bone marrow fibrosis, anemia, splenomegaly, extramedullary hematopoiesis (EMH), constitutional symptoms, cachexia, leukemic progression and shortened survival.
Diagnostic Criteria for Essential Thrombocytosis (ET)
Essential Thrombocytosis (ET) is the only chronic myeloproliferative disorder (MPD) without a specific phenotype. Because isolated thrombocytosis can be the initial clinical manifestation of polycythemia vera (PV), primary myelofibrosis (PMF), or chronic myelogenous leukemia, ET is not only a diagnosis of exclusion, it should also not be considered a single disease entity.
New Diagnostic Criteria for Common Variable Immune Deficiency (CVID)
Common variable immunodeficiency disorders (CVIDs) are the most frequent symptomatic primary immune deficiency condition in adults. The genetic basis for the condition is not known and no single clinical feature or laboratory test can establish the diagnosis; it has been a diagnosis of exclusion. In areas of uncertainty, diagnostic criteria can provide valuable clinical information.
Diagnostic Criteria for Aplastic Anemia (AA)
Aplastic anaemia is a rare and heterogeneous disorder. It is defined as pancytopenia with a hypocellular bone marrow in the absence of an abnormal infiltrate or marrow fibrosis.
TG18/TG13 Diagnostic Criteria for Acute Cholangitis
The diagnostic and severity grading criteria on the 2018 Tokyo Guidelines (TG18) are used worldwide as the primary standard for management of acute cholangitis (AC).
Gout Classification Criteria
Gout, which is characterized by deposition of monosodium urate monohydrate (MSU) in synovial fluid and other tissues, is the most common form of inflammatory arthritis.
Criteria for the Diagnosis of POEMS Syndrome
POEMS syndrome is a rare paraneoplastic syndrome due to an underlying plasma cell disorder (PCD). The acronym, which was coined by Bardwick in 1980, refers to several, but not all, of the features of the syndrome: polyradiculoneuropathy, organomegaly, endocrinopathy, monoclonal PCD, and skin changes.
2017 ACR–EULAR Classification Criteria for Primary Sjögren’s Syndrome
A diagnosis of primary Sjögren’s syndrome is often made on the basis of a classic triad of symptoms: dryness of the mouth and eyes, fatigue, and pain. Systemic complications, which are present in 30 to 40% of patients, may provide the first clues to the disease.
