| hepatitis, chronic | A collective term for a clinical and pathological syndrome which has several causes and is characterised by varying degrees of hepatocellular necrosis and inflammation. Specific forms of chronic hepatitis include autoimmune hepatitis (hepatitis, autoimmune), chronic hepatitis b (hepatitis b, chronic), chronic hepatitis c (hepatitis c, chronic), chronic hepatitis d (hepatitis d, chronic), indeterminate chronic viral hepatitis, cryptogenic chronic hepatitis and drug-related chronic hepatitis (hepatitis, chronic, drug-induced). (12 Dec 1998) |
|---|---|
| hepatitis, chronic, drug-induced | An inflammatory disease of the liver, lasting six months or more, and caused by an adverse drug effect. The adverse effect may result from a direct toxic effect of a drug or metabolite, or an idiosyncratic response to a drug or metabolite. The clinical and histological changes can mimic viral or autoimmune hepatitis. (12 Dec 1998) |
| hepatitis d, chronic | Inflammatory disease of the liver caused by hepatitis d virus in conjunction with hepatitis b virus and lasting six months or more. (12 Dec 1998) |
| stricture of the oesophagus, chronic | A narrowing or closure of the normal opening of the swallowing tube leading to the stomach, usually caused by scarring from acid irritation. A common complication of chronic gastroesophageal reflux disease (gerd). Several procedures are available for stretching (dilating) the strictures without having to resort to surgery. One of the procedures involves placing a deflated balloon across the stricture at the time of endoscopy. The balloon is then inflated, thereby opening the narrowingcaused by the stricture. Another method involves inserting tapered dilators of different sizes through the mouth into the oesophagus to dilate the stricture. (12 Dec 1998) |
| systemic-onset juvenile chronic arthritis | See: Systemic-onset juvenile rheumatoid arthritis (still's disease). (12 Dec 1998) |
| illness, chronic | An illness that has persisted for a long period of time. It is a continuing disease process. (12 Dec 1998) |
| oesophageal stricture, chronic | A longstanding narrowing or closure of the normal opening of the swallowing tube leading to the stomach, usually caused by scarring by acid irritation. Narrowing of the oesophagus. A common complication of chronic gastroesophageal reflux disease (GERD). Severa procedures are available for stretching (dilating) the strictures without having to resort to surgery. One of the procedures involves placing a deflated balloon across the stricture at the time of endoscopy. The balloon is then inflated, thereby opening the narrowingcaused by the stricture. Another method involves inserting tapered dilators of different sizes through the mouth into the oesophagus to dilate the stricture. (12 Dec 1998) |
| ophthalmoplegia, chronic progressive external | One of the mitochondrial encephalomyopathies characterised by slowly progressive paralysis of the extraocular muscles. Muscle biopsies disclose the characteristic ragged red fibres and large numbers of mitochondria with deleted DNA. (12 Dec 1998) |
| jaundice, chronic idiopathic | A familial chronic form of nonhemolytic jaundice thought to be due to a defect in the excretion of conjugated bilirubin and certain other organic anions (e.g., sulfobromophthalein) by the liver. It is characterised by the presence of a brown, coarsely granular pigment in the hepatic cells, which is pathognomonic of the condition. (12 Dec 1998) |

| juvenile chronic arthritis, systemic-onset | See: Juvenile rheumatoid arthritis, systemic-onset (still's disease). (12 Dec 1998) |
| kidney failure, chronic | An irreversible and usually progressive reduction in renal function in which both kidneys have been damaged by a variety of diseases to the extent that they are unable to adequately remove the metabolic products from the blood and regulate the body's electrolyte composition and acid-base balance. Chronic kidney failure requires haemodialysis or surgery, usually kidney transplantation. (12 Dec 1998) |
| fatigue syndrome, chronic | Syndrome of unknown cause, characterised by clinically evaluated, unexplained persistent or relapsing chronic fatigue of at least six months' duration which is not the result of ongoing exertion; is not substantially alleviated by rest; and results in substantial reduction of previous levels of occupational, educational, social, or personal activities. Common concurrent symptoms (of six months duration) include impairment of memory or concentration, diffuse pain, sore throat, tender lymph nodes, headaches of a new type, pattern, or severity, and unrefreshing sleep. The aetiology is suspected to be viral or immunologic. There are suggestions that chronic fatigue syndrome (sometimes called myalgic encephalomyelitis) may be identical to neurasthenia and fibromyalgia. (12 Dec 1998) |
| air-conditioner lung | An extrinsic allergic alveolitis caused by forced air contaminated by thermophilic actinomycetes and other organisms. (05 Mar 2000) |
