| nodular headache | Radiating pain in the head accompanied by nodular swellings in the splenius, frontalis, trapezius, and other muscles. (05 Mar 2000) |
| symptomatic headache | A headache secondary to another organic condition. Synonym: reflex headache. (05 Mar 2000) |
| organic headache | Headache due to intracranial disease. (05 Mar 2000) |
| tension headache | <neurology> A benign form of headache that results from the painful spasm (muscle tightness) and inflammation of muscles of the head and neck. Tension headache is one of the most common forms of headache. Spasm and contraction of the head and neck muscles may occur in response to fatigue, overuse, eye strain, excessive smoking, stress, anxiety or depression. Sleeping in an abnormal position or prolonged work involving immobilisation of the neck in one position (typing, computers, etc.) are considered common triggers. Exercising and stretching the muscles of the head and neck can reduce the occurrence of muscle tension headaches. (13 Jan 1998) |
| fibrositic headache | Headache centreed in the occipital region due to fibrositis of the occipital muscles; tender areas are present and, commonly, tender nodules are found in the scalp in the lower occipital region. (05 Mar 2000) |
| allergy | 1. <immunology> A state of hypersensitivity induced by exposure to a particular antigen (allergen) resulting in harmful immunologic reactions on subsequent exposures, the term is usually used to refer to hypersensitivity to an environmental antigen (atopic allergy or contact dermatitis) or to drug allergy. The original meaning, now obsolete, included all states of altered immunologic reactivity, immunity as well as hypersensitivity. Gell and Coombs used the term allergic reaction to mean any harmful immunologic reaction causing tissue injury. 2. <study> The medical specialty dealing with diagnosis and treatment of allergic disorders. (18 Nov 1997) |
| allergy and immunology | A medical specialty concerned with the hypersensitivity of the individual to foreign substances and protection from the resultant infection or disorder. (12 Dec 1998) |
| allergy desensitization | 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 injections ( shots ) are usually required for 3-5 years. (12 Dec 1998) |
| allergy shots | See Allergy desensitization. (12 Dec 1998) |
| allergy skin test | 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) |
| allergy testing | <investigation> A common method of screening a patient for potential allergies. May be given as a patch or a skin test (injection). (27 Sep 1997) |
| atopic allergy | <immunology> An allergic reaction with strong family tendencies. (09 Oct 1997) |
| bacterial allergy | The concept that the atopic kind of type I allergic reactions may be caused by bacterial allergens, the delayed type of skin test, so-called because of its early association with bacterial antigens (e.g., the tuberculin test). (05 Mar 2000) |
| physical allergy | Excessive response to factors in the environment such as heat or cold. (05 Mar 2000) |
