New diagnostic criteria and the treatment policy for adrenal subclinical Cushing’s syndrome (SCS) are proposed on behalf of the Japan Endocrine Society. The current diagnostic criteria for SCS have elicited two main problems: (i) the relatively low reliability of a low range of serum cortisol essential for the diagnosis by an overnight 1-mg dexamethasone suppression test (DST); (ii) different cutoff values for serum cortisol after a 1-mg DST compared with those of other countries.
Syndrome
Diagnostic Criteria for Dengue Hemorrhagic Fever (DHS) and Dengue Shock Syndrome (DSS)
Dengue hemorrhagic fever is an immunopathologic disease; dengue virus–antibody immune complexes trigger release of vasoactive mediators by macrophages. The mediators increase vascular permeability, causing vascular leakage, hemorrhagic manifestations, hemoconcentration, and serous effusions, which can lead to circulatory collapse (ie, dengue shock syndrome).
Diagnosis of Posterior Reversible Encephalopathy Syndrome (PRES)
The posterior reversible encephalopathy syndrome (PRES) is a neurological disorder of (sub)acute onset characterized by varied neurological symptoms, which may include headache, impaired visual acuity or visual field deficits, disorders of consciousness, confusion, seizures, and focal neurological deficits.
Risk Factors of Budd-Chiari Syndrome
Primary Budd-Chiari syndrome is characterized by a blocked hepatic venous outflow tract at various levels from small hepatic veins to inferior vena cava, resulting from thrombosis or its fibrous sequellae. This rare disease affects mainly young adults. Multiple risk factors have been identified and are often combined in the same patient.
Diagnostic Criteria for Infantile Spasms and West Syndrome
West syndrome is characterized by a specific type of seizure ( infantile spasms) and developmental regression.
The gold standard method of diagnosing infantile spasms is to capture them on video-EEG to confirm the ictal correlate of the seizure.
WHO Criteria for Diagnosis of Serrated Polyposis Syndrome (SPS)
Serrated polyposis syndrome (SPS) (previously hyperplastic polyposis) is defined by number and size of serrated polyps in the colon and rectum, but the definition is purely arbitrary and there is no known genotype.
SPS is associated with a high risk of colorectal cancer, not only in the affected patient, but also family members. The carcinogenesis can be rapid, with several series describing interval cancers occurring quickly.
Sydney Classification Criteria for Definite Antiphospholipid Syndrome (APS)
The antiphospholipid syndrome (APS) is characterized by thrombotic and/or pregnancy morbidity associated with the presence of persistent antiphospholipid antibodies (aPLs). There are many other clinical manifestations associated with persistent aPL (including immune thrombocytopenia, livedo reticularis, migraine, valvular heart disease and cognitive dysfunction).
Diagnostic Criteria for Guillain–Barré Syndrome (GBS)
Guillain–Barré syndrome (GBS) is a rare, but potentially fatal, immune-mediated disease of the peripheral nerves and nerve roots that is usually triggered by infections.
Diagnostic Criteria for Premenstrual Syndrome (PMS)
Premenstrual disorders consist of psychiatric or somatic symptoms that develop within the luteal phase of the menstrual cycle, affect the patient’s normal daily functioning, and resolve shortly after menstruation. The luteal phase begins after ovulation and ends with the start of menstruation. The American Congress of Obstetricians and Gynecologists (ACOG) includes psychiatric and physical symptoms in describing premenstrual syndrome (PMS).
Case Definition for Severe Acute Respiratory Syndrome (SARS)
Severe acute respiratory syndrome (SARS) is a viral respiratory illness caused by a coronavirus, called SARS-associated coronavirus (SARS-CoV).
