| echinococcus disease | Infection caused by tapeworms of the genus echinococcus. The larval stage is called hydatid or hydatid cyst and develops in almost all mammals, especially domestic and farm animals, and in man under certain epidemiological conditions. The liver, lungs, and kidney are particularly common sites of development and infestation. . Echinococcosis, hepatic and echinococcosis, pulmonary are also available. (12 Dec 1998) |

| echinococcus | <dermatology, microbiology> A tissue infection by the larval stage of the Echinococcus granulosus worm. This disease is common in South America, the Middle East, Asia and Africa. Sporadic cases have been reported in the us. Infection occurs after ingestion of eggs in infected dog faeces. The infection is carried to the liver where cysts form. Cysts may also form in the lungs, bone, brain, kidney, muscles and spleen. Symptoms include abdominal pain, itching, cough, haemoptysis, chest pain and fever. Treatment includes the surgical removal of cysts from the tissue. (19 Jan 1998) |

| echinococcus cyst | A cyst formed in the liver, or, less frequently, elsewhere, by the larval stage of Echinococcus, chiefly in ruminants; two morphological forms caused by Echinococcus granulosus are found in humans: the unilocular hydatid cyst and the osseous hydatid cyst; a third form in humans is the alveolar hydatid cyst, caused by Echinococcus multilocularis. Synonym: echinococcus cyst, hydatid. (05 Mar 2000) |
| aaa disease | Endemic anaemia of ancient Egypt, ascribed in the Papyrus Ebers to intestinal infestation with ancylostoma; now called ancylostomiasis. (05 Mar 2000) |
| ABO haemolytic disease of the newborn | Erythroblastosis foetalis due to maternal-foetal incompatibility with respect to an antigen of the ABO blood group; the foetus possesses A or B antigen which is lacking in the mother, and the mother produces immune antibody which causes haemolysis of foetal erythrocytes.

| accumulation disease | A disease characterised by abnormal accumulation of a metabolic product in certain cells and tissues; examples include the mucopolysaccharidoses, lipoidoses. (05 Mar 2000) |
| Acosta's disease | A condition that results from prolonged exposure to high altitude. Symptoms include a continuous dry cough, shortness of breath, poor exercise tolerance, dizziness, headache, sleep difficulty, anorexia, confusion, fatigue and a rapid pulse. Treatment includes the immediate movement to a lower altitude. Prophylaxis has been accomplished successfully with the use of acetazolamide (Diamox). (27 Sep 1997) |

| Addison-Biermer disease | <haematology> A form of anaemia (low red blood cell counts) that results when the bone marrow fails to produce adequate numbers of red blood cells due to a deficiency in vitamin B12. Intrinsic factor, necessary for normal B12 absorption, may be the underlying cause for B12 deficiency if is not produced in the gastric glands (in the stomach). Origin: Gr. Haima = blood (27 Sep 1997) |
| Addison's disease | <endocrinology> A rare endocrine disease that results from the underproduction of aldosterone and cortisol (hormones) by the adrenal glands. Symptoms include weakness, low blood pressure, anaemia, low blood sugar and electrolyte abnormalities. (27 Sep 1997) |
| adult-onset still's disease | Although Still's disease was first described in children, it is known to begin in adults. See: Still's disease. (12 Dec 1998) |
| Akabane disease | A disease of cattle, sheep and goats, caused by the Akabane virus and characterised by foetal or neonatal arthrogryposis and hydranencephaly, abortions, and foetal death; the causative virus is transmitted by mosquitoes in Japan and by the midge Culicoides brevitarsis in Australia.

| akamushi disease | See Typhus, scrub. (12 Dec 1998) |
| Akureyri disease | An epidemic disease characterised by stiffness of the neck and back, headache, diarrhoea, fever, and localised muscular weakness; restricted almost exclusively to adults, affecting women more than men; probably viral in origin.
