| desensitization, allergy | Stimulation of the immune system with gradually increasing doses of the substances to which a person is allergic, the aim being to modify or stop the allergy war (by reducing the strength of the IgE and its effect on the mast cells). This form of treatment is very effective for allergies to pollen, mites, cats, and especially stinging insects (e.g., bees, hornets, yellowjackets, wasps, velvet ants, fire ants). Allergy immunotherapy usually takes 6 months to a year to become effective and shots (injections) are usually required for 3-5 years. (12 Dec 1998) |

| drug allergy | Sensitivity (hypersensitivity) to a drug or other chemical. (05 Mar 2000) |
| immediate allergy | A type I allergic reaction; so called because in a sensitised subject the reaction becomes evident usually within minutes after contact with the allergen (antigen), reaches its peak within an hour or so, then rapidly recedes. See: immediate reaction, anaphylaxis. Compare: delayed allergy. (05 Mar 2000) |

| insulin allergy | When a person's body has an allergic or bad reaction to taking insulin made from pork or beef or from bacteria, or because the insulin is not exactly the same as human insulin or because it has impurities. The allergy can be of two forms. Sometimes an area of skin becomes red and itchy around the place where the insulin is injected. This is called a local allergy. In another form, a person's whole body can have a bad reaction. This is called a systemic allergy. The person can have hives or red patches all over the body or may feel changes in the heart rate and in the rate of breathing. A doctor may treat this allergy by prescribing purified insulins or by desensitisation. See: desensitisation. (09 Oct 1997) |
| test, skin, for allergy | A test done on the skin to identify the allergy substance (allergen) triggering the allergic reaction. A small amount of the suspected allergy substance is placed on the skin. The skin is then gently scratched through the small drop with a special sterile needle. If the skin reddens and, more importantly, swells, then allergy to that substance is probable. (12 Dec 1998) |
| latent allergy | Allergy that causes no signs or symptoms but can be revealed by means of certain immunologic tests with specific allergens. (05 Mar 2000) |
| complete abortion | The complete expulsion or extraction from its mother of a foetus or embryo, complete expulsion of any other product of gestation. (e.g., hydatidiform mole). (05 Mar 2000) |
| complete achromatopsia | Achromatopsia with absent colour vision, nystagmus, reduced visual acuity, and light aversion. Synonym: rod monochromatism, typical achromatopsia. (05 Mar 2000) |
| complete antibody | An antibody which causes agglutination of erythrocytes when they are suspended either in saline or in a protein medium. (05 Mar 2000) |
| complete antigen | Any antigen capable of stimulating the formation of antibody with which it reacts in vivo or in vitro, as distinguished from incomplete antigen (hapten). (05 Mar 2000) |
| complete ascertainment | Method by which all families with at least one affected individual in a population are certain or have an equal chance of being identified by survey or an appropriate random sampling technique. (05 Mar 2000) |
| complete atrioventricular dissociation | A-V dissociation not interrupted by ventricular captures. Synonym: complete A-V block. (05 Mar 2000) |
| complete A-V block | complete atrioventricular dissociation, complete A-V dissociation |
| complete blood count | <haematology, investigation> The number of red blood cells, white blood cells and platelets are present in the patients sample of blood is determined. most common test done on the blood. Acronym: CBC Synonym: full blood count. (16 Mar 1998) |
