| eosinophilic gastroenteritis | <radiology> Eosinophilic infiltration of mucosa, submucosa, and muscularis of small bowel with or without stomach, stomach (almost always limited to antrum): enlarged gastric rugae, cobblestone nodules, polyps (=mucosal type), rigid wall with narrowed antrum/pylorus, bulky inramural mass up to 9 cm (=muscular type), wet stomach, ulcers rare, may have ascites, small bowel (predominantly jejunum), thickening and distortion of folds (=mucosal type), effacement of mucosa and narrowing of lumen (=muscular type), prognosis: tendency to spontaneous remission, treatment: steroids; removal of sensitizing agent (12 Dec 1998) |

| eosinophilic granuloma | <oncology, tumour> An immunologic disorder of unknown cause where there is proliferation of histiocytes (a type of cell in the immune system) in the bloodstream. The disorder is characterised by inflammation of the bronchioles and small pulmonary vessels that leads to fibrosis and destruction of alveolar cell walls. Cigarette smoking is considered a risk factor. Individuals with this disorder are also at increased risk for spontaneous pneumothorax. Symptoms include cough, chest pains, shortness of breath, fever, weight loss and malaise. Bronchoscopy with biopsy confirms the diagnosis. Childhood forms exist and cause more systemic symptoms and findings such as failure to thrive, weight loss, fevers, irritability, rash and bone pains. Treatment is with corticosteroids.

| eosinophilic leukaemia | Eosinophilocytic leukaemia, a form of granulocytic leukaemia in which there are conspicuous numbers of eosinophilic granulocytes in the tissues and circulating blood, or in which such cells are predominant; in chronic disease of this type, the total white blood cell count may be as high as 200,000 to 250,000 per cu mm, with as many as 80 or 90% being eosinophils, chiefly adult forms. (05 Mar 2000) |
| eosinophilic leukocyte | A polymorphonuclear leukocyte characterised by many large or prominent, refractile, cytoplasmic granules that are fairly uniform in size and bright yellow-red or orange when treated with Wright's or similar stains; the nuclei are usually larger than those of neutrophils, do not stain as deeply, and characteristically have two lobes (a third lobe is sometimes interposed on the connecting strand of chromatin); these leukocyte's are motile phagocytes with distinctive antiparasitic functions. Synonym: acidophilic leukocyte, eosinocyte, eosinophil, eosinophile, oxyphil, oxyphile, oxyphilic leukocyte. (05 Mar 2000) |
| eosinophilic leukocytosis | A form of relative leukocytosis in which the greatest proportionate increase is in the eosinophils. Synonym: eosinophilia. (05 Mar 2000) |
| eosinophilic leukopenia | A decrease in the number of eosinophilic granulocytes normally present in the circulating blood. (05 Mar 2000) |
| eosinophilic lung disease | <radiology> Idiopathic: Loeffler pneumonia, chronic eosinophilic pneumonia, hypereosinophilic syndrome, specific: drugs (e.g., nitrofurantoin), parasites, fungi (ABPA, bronchocentric granulomatosis), vasculitis / granulomatosis: Wegener's granulomatosis, polyarteritis nodosa, sarcoidal angiitis (12 Dec 1998) |
| eosinophilic meningitis | Infection of animals and man with nematodes of the genus Angiostrongylus. Synonym: eosinophilic meningitis. (05 Mar 2000) |
| eosinophilic meningoencephalitis | A disease caused by infection with the rat lungworm, Angiostrongylus cantonensis, whose larvae, ingested with infected slugs or land snails (or some unidentified transport host), migrate from intestine to the meninges of the brain where the disease is produced; it is usually mild, of short duration, and characterised by fever, eosinophilia, and white blood cells (rarely nematode larvae) in the spinal fluid. (05 Mar 2000) |
| eosinophilic pneumonia | A self-limiting inflammation in the lungs where there is associated infiltration of eosinophils into lung tissue. Chest X-ray reveals pulmonary infiltrates and full blood count (CBC) shows increased numbers of eosinophils. The cause is unknown and the disease often resolves without treatment. Some forms may be treated with oral corticosteroids. Complications include restrictive cardiomyopathy due to fibrosis of the lining of the heart. (27 Sep 1997) |
| eosinophilic pneumonopathy | A self-limiting inflammation in the lungs where there is associated infiltration of eosinophils into lung tissue. Chest X-ray reveals pulmonary infiltrates and full blood count (CBC) shows increased numbers of eosinophils. The cause is unknown and the disease often resolves without treatment. Some forms may be treated with oral corticosteroids. Complications include restrictive cardiomyopathy due to fibrosis of the lining of the heart. (27 Sep 1997) |
| eosinophilic pustular folliculitis | A dermatosis characterised by sterile pruritic papules and pustules that coalesce to form plaques with papulovesicular borders; spontaneous exacerbations and remissions may be accompanied by peripheral leukocytosis, eosinophilia, or both, and may result in eventual destruction of hair follicles and formation of eosinophilic abscesses. The disease has been reported in AIDS, and a possibly separate form of eosinophilic pustular folliculitis occurs in infants. Synonym: Ofuji's disease. (05 Mar 2000) |
| fasciitis, eosinophilic | A disease which leads to inflammation and thickening of the skin and fascia. (The fascia is a lining tissue under the skin that covers a surface of underlying tissues. When the fascia is inflamed, the condition is referred to as fasciitis. ) In eosinophilic fasciitis, the involved fascia is inflamed with the eosinophil white blood cells. There is progressive thickening, and often redness and warmth, and hardness of the skin surface. (12 Dec 1998) |
| accelerated reaction | A response occurring in a shorter time than expected; the cutaneous manifestations occurring during the period between the second and tenth day following smallpox vaccination; because it is intermediate between a primary reaction and an immediate reaction, it is regarded as evidence of some degree of resistance. Synonym: vaccinoid reaction. (05 Mar 2000) |
| acid reaction | Any test by which an acid reaction is recognised such as the change of blue litmus paper to red, an excess of hydrogen ions over hydroxide ions in aqueous solution indicated by a pH value less than 7 (at 22캜). Compare: dissociation constant of water. (05 Mar 2000) |
