Syndrome
A characteristic symptom complex.
Year introduced: 1991(1972)
Lennox Gastaut Syndrome
A childhood-onset epilepsy syndrome.
Year introduced: 2015
Atypical Hemolytic Uremic Syndrome
An hereditary hemolytic uremic syndrome associated with variations in the gene that encodes COMPLEMENT FACTOR H, or the related proteins CFHR1 and CFHR3. Disease often progresses to CHRONIC KIDNEY FAILURE without the prodromal symptoms of ENTEROCOLITIS and DIARRHEA that characterize typical hemolytic uremic syndrome.
Middle East Respiratory Syndrome Coronavirus
A coronavirus first reported in the summer of 2012 in a pneumonia patient in SAUDI ARABIA. It is related to SEVERE ACUTE RESPIRATORY SYNDROME-RELATED CORONAVIRUS. MERS-CoV has an estimated incubation period of 12 days and symptoms include renal failure and severe acute pneumonia with often fatal outcome.
Nicolau Syndrome
An uncommon complication of INTRAMUSCULAR INJECTION leading to variable degrees of necrosis of skin and underlying tissue.
Anticholinergic Syndrome
Adverse drug effects associated with CHOLINERGIC ANTAGONISTS. Clinical features include TACHYCARDIA; HYPERTHERMIA; MYDRIASIS, dry skin and dry mucous membranes, decreased bowel sounds and urinary retention in peripheral anticholinergic syndrome; and HALLUCINATIONS; PSYCHOSES; SEIZURES; and COMA in central anticholinergic syndrome.
Year introduced: 2014
Nodding Syndrome
Unexplained neurologic condition characterized by episodes of atonic seizures, convulsions or staring spells with further cognitive decline.
Drug Hypersensitivity Syndrome
Severe drug eruption characterized by high fever, erythematous rash and inflammation of internal organ(s).
Bland White Garland Syndrome
A congenital coronary vessel anomaly in which the left main CORONARY ARTERY originates from the PULMONARY ARTERY instead of from AORTA. The congenital heart defect typically results in coronary artery FISTULA; LEFT-SIDED HEART FAILURE and MITRAL VALVE INSUFFICIENCY during the first months of life.
May-Thurner Syndrome
A compression of ILIAC VEIN that results in a decreased flow in the vein and in the left LOWER EXTREMITY due to a vascular malformation. It may result in left leg EDEMA, pain, iliofemoral DEEP VENOUS THROMBOSIS and POSTTHROMBOTIC SYNDROME. Compression of the left common ILIAC VEIN by the right common ILIAC ARTERY against the underlying fifth LUMBAR VERTEBRA is the typical underlying malformation.
Year introduced: 2013
Alice in Wonderland Syndrome
Neurological condition characterized by disturbances in VISUAL PERCEPTION, most often of BODY SCHEMA, TIME PERCEPTION and HALLUCINATIONS. It is associated with MIGRAINE, infections (e.g., INFECTIOUS MONONUCLEOSIS), FEVER, EPILEPSY, and other neurological and psychiatric disorders.
Hereditary Breast and Ovarian Cancer Syndrome
Autosomal dominant HEREDITARY CANCER SYNDROME in which a mutation most often in either BRCA1 or BRCA2 is associated with a significantly increased risk for breast and ovarian cancers.
Year introduced: 2012
Hand-Foot Syndrome
Chemotherapy-induced dermal side effects that are associated with the use of various CYTOSTATIC AGENTS. Symptoms range from mild ERYTHEMA and/or PARESTHESIA to severe ulcerative dermatitis with debilitating pain involving typically palmoplantar and intertriginous areas. These cutaneous manifestations are sometimes accompanied by nail anomalies.
Kasabach-Merritt Syndrome
Rapidly growing vascular lesion along the midline axis of the neck, upper trunk, and extremities that is characterized by CONSUMPTION COAGULOPATHY; THROMBOCYTOPENIA; and HEMOLYTIC ANEMIA. It is often associated with infantile Kaposiform HEMANGIOENDOTHELIOMA and other vascular tumors such as tufted ANGIOMA.
Heterotaxy Syndrome
Abnormal thoracoabdominal VISCERA arrangement (visceral heterotaxy) or malformation that involves additional CONGENITAL HEART DEFECTS (e.g., heart isomerism; DEXTROCARDIA) and/or abnormal SPLEEN (e.g., asplenia and polysplenia). Irregularities with the central nervous system, the skeleton and urinary tract are often associated with the syndrome.
Cardio-Renal Syndrome
Condition where a primary dysfunction of either heart or kidney results in failure of the other organ (e.g., HEART FAILURE with worsening RENAL INSUFFICIENCY).
Chilaiditi Syndrome
Interposition of a portion of the colon (e.g., SIGMOID COLON) between the liver and the diaphragm. It is associated with abdominal pain, vomiting, constipation, anorexia and volvulus. Chilaiditi anomaly refers to asymptomatic interposition.
Renal Nutcracker Syndrome
Left RENAL VEIN compression between the AORTA, ABDOMINAL and the SUPERIOR MESENTERIC ARTERY. Variable symptoms include HYPERTENSION, RENOVASCULAR; HEMATURIA; and VARICOSE VEINS.
Medial Tibial Stress Syndrome
SKELETAL MUSCLE pain and tenderness along the posteromedial TIBIA resulting from exercise such as running and other physical activity.
Year introduced: 2011
CHARGE Syndrome
Rare disease characterized by COLOBOMA; CHOANAL ATRESIA; and abnormal SEMICIRCULAR CANALS. Mutations in CHD7 protein resulting in disturbed neural crest development are associated with CHARGE Syndrome.
