| chronic symptomatic HIV infection | This refers to an HIV infection that is characterised by signs and symptoms of HIV that are not life-threatening. Examples include oral thrush, gingivitis, seborrheic dermatitis, molluscum contangiosum, fevers, fatigue, lymph node swelling, malaise and weight loss. This stage can be a signal for the conversion from asymptomatic HIV disease to HIV disease (moe pronouced symptoms include joint pains). AIDS is diagnosed after HIV disease has started to manifest life-threatening oppotunistic infections (for example pneumocystis, cryptosporidium, toxoplasmosis, etc). (27 Sep 1997) |

| chronic trypanosomiasis | A chronic disease of humans caused by Trypanosoma brucei gambiense in northern and sub-Saharan Africa from Senegal east to Sudan and Uganda; characterised by splenomegaly, drowsiness, an uncontrollable urge to sleep, and the development of psychotic changes; basal ganglia and cerebellar involvement commonly lead to chorea and athetosis; the terminal phase of the disease is characterised by wasting, anorexia, and emaciation that gradually leads to coma and death, usually from intercurrent infection. Synonym: chronic African sleeping sickness, chronic trypanosomiasis, West African sleeping sickness, West African trypanosomiasis. (05 Mar 2000) |

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) |

| 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) |
