| 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) |

| 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) |

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) |
