| lyme disease serology | A blood test which measures for the presence of Lyme disease antibodies. A nonreactive or serum titre of less than 1:256 is normal. A rising titre over time is more diagnostic. False positives due occur in those with rheumatoid arthritis and lupus. (27 Sep 1997) |
|---|
| lyme disease | <infectious disease> A bacterial disease caused by the micro-organism (spirochete) Borrelia burgdorferi. This bacterium was discovered in 1982, although the clinical disease was first described in 1977. Infection occurs after the bite of an infected tick. The incubation period is approximately 14 days. Symptoms include a large circular red rash at the bite site (50-60% of cases), malaise, fever, headache, muscle aches and swollen lymph nodes. If untreated may progress to arthritis and compromise heart function. (27 Sep 1997) |

| 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.

| 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) |
