| allergic alveolitis | <chest medicine> Inflammation of the lungs which occurs secondary to exposure to a chemical, organic dust, fungus or mould. Chronic exposure can lead to chronic lung changes evident on chest X-ray. Symptoms include cough, fever, shortness of breath and wheezing. See: bird-handler's disease. (27 Sep 1997) |
|---|---|
| allergic angiitis | An acute form of vasculitis which may affect the skin only, but also may involve other organs, with a polymorphonuclear infiltrate in the walls of and surrounding small (dermal) vessels. Nuclear fragments are formed by karyorrhexis of the neutrophils. See: leukocytoclastic vasculitis. Synonym: allergic angiitis, hypersensitivity vasculitis. (05 Mar 2000) |
| allergic asthma | <chest medicine> A disease process that is characterised by paradoxical narrowing of the bronchi (lung passageways) making breathing difficult. Treatment includes bronchodilators which are given orally or delivered as an aerosol (inhaled). Corticosteroids are reserved for more difficult cases. Symptoms include wheezing, difficulty breathing (particularly exhaling air) and tightness in the chest. Factors which can exacerbate asthma include rapid changes in temperature or humidity, allergies, upper respiratory infections, exercise, stress or smoke (cigarette). See: status asthmaticus. (27 Sep 1997) |
| allergic bronchopulmonary aspergillosis | <radiology> ABPA: Aspergillus fumigatus hypersensitivity, mucoid impaction of bronchi distal to lobar bronchus, mucus plugs contain fungi, eosinophils, XR: Y-shaped density (mucus plug wedged in bronchi) (12 Dec 1998) |
| allergic conjunctivitis | <ophthalmology> An inflammatory condition of the conjunctiva secondary to an allergic stimulus. Common symptoms include itchy, red and tearing eyes (27 Sep 1997) |
| allergic contact dermatitis | A delayed type IV allergic reaction of the skin with varying degrees of erythema, oedema, and vesiculation resulting from cutaneous contact with a specific allergen. Synonym: contact allergy. (05 Mar 2000) |
| allergic coryza | A rhinitis in an allergic individual due to the presence of an agent to which he is hypersensitive. (05 Mar 2000) |
| allergic eczema | Macular, papular, or vesicular eruption due to an allergic reaction. (05 Mar 2000) |
| allergic extract | Extract (usually containing protein) from various sources, e.g., food, bacteria, pollen, and the like, suspected of specific action in stimulating manifestations of allergy; may be used for skin testing or desensitization. Synonym: allergic extract. (05 Mar 2000) |
| allergic granulomatosis | <syndrome> Widespread necrotizing angiitis with granulomas. Pulmonary involvement is frequent. Asthma or other respiratory infection may precede evidence of vasculitis. Eosinophilia and lung involvement differentiate this disease from polyarteritis nodosa. (12 Dec 1998) |
| allergic granulomatous angiitis | <syndrome> Widespread necrotizing angiitis with granulomas. Pulmonary involvement is frequent. Asthma or other respiratory infection may precede evidence of vasculitis. Eosinophilia and lung involvement differentiate this disease from polyarteritis nodosa. (12 Dec 1998) |
| allergic inflammation | <immunology> The bodys response to an allergic stimulus. This can be localised to one area or generalised and may include: rash, itching, hives, swelling, difficulty breathing, and/or low blood pressure. (27 Sep 1997) |
| allergic purpura | Nonthrombocytopenic purpura due to sensitization to foods, drugs, and insect bites. Synonym: anaphylactoid purpura. (05 Mar 2000) |
| allergic reaction | <immunology> The bodys response to an allergic stimulus. This can be localised to one area or generalised and may include: rash, itching, hives, swelling, difficulty breathing, and/or low blood pressure. (27 Sep 1997) |
| allergic rhinitis | <immunology> An inflammatory response in the nasal passages to an allergic stimulus. Often includes: nasal congestion, sneesing, runny or itchy nose. (27 Sep 1997) |
