Eosinophilic gastroenteritis
Eosinophilic gastroenteritis Infection and swelling of the lining of the stomach, small intestine, or large intestine. The infection is caused by white blood cells (eosinophils).
RELATED TERMS--------------------------------------
Infection
Anything that invades the body and reproduces. Infections can be bacteria, protozoa, fungi, or viruses. Bacteria and fungi are one celled creatures that cause many infections including strep throat, bladder infections, and some lung infections. Fungi cause “athlete’s foot” and thrush, an infection in the mouth. Protozoa are small organisms with many cells that can cause infections in the guts or in the lungs. Most healthy people do not get protozoal infections, but people with suppressed immune systems can. Viruses are not really organisms; they are tiny particles that can live only inside another cell. They reproduce by taking over a cell and causing that cell to make more virus particles, rather than doing what the cell is supposed to do. Viruses cause most colds and flu cases.
Stomach
The organ between the esophagus and the small intestine. The stomach is where digestion of protein begins.
Intestine
The tube involved in digestion and extending from the stomach to the anus. Consists of the small intestine and the large intestine.
Blood
The life-maintaining fluid which is made up of plasma, red blood cells (erythrocytes), white blood cells (leukocytes), and platelets; blood circulates through the body's heart, arteries, veins, and capillaries; it carries away waste matter and carbon dioxide, and brings nourishment, electrolytes, hormones, vitamins, antibodies, heat, and oxygen to the tissues.
SIMILAR TERMS--------------------------------------
Eosinophil
A polymorphonuclear leukocyte with large eosinophilic (i.e. red) cytoplasmic granules.
Eosinophil chemotactic factor of anaphylaxis (ECF-A)
A substrate released from mast cells during anaphylaxis which attracts eosinophils.
Eosinophilia
An abnormally high number of eosinophils in the blood. Normally, eosinophils constitute 1 to 3% of the peripheral blood leukocytes, at a count of 350 to 650 per cubic millimeter. Eosinophilia can be categorized as mild (less than 1500 eosinophils per cubic millimeter), moderate (1500 to 5000 per cubic millimeter), or severe (more than 5000 per cubic millimeter).
Eosinophilia-myalgia syndrome
Resembles eosinophilic fasciitis - due to L-Tryptophan.
Eosinophilic fasciitis
A scleroderma-like condition in which there is skin thickening and tethering with oedema along with thickening of the sub-epidermal fascia and infiltration with eosinophils. (Shulman's syndrome)
Eosinophilic granuloma
A form of Histiocytosis-X. A rare cause of back pain in adolescence which may cause vertebral collapse.
Eosinophilic meningitis
Meningitis with a high percentage of eosinophils (a type of white blood cell) in the cerebrospinal fluid (CSF). The usual cause is the parasite Angiostrongylus cantonensis, also known as the rat lungworm. People become infected with this parasite by ingesting its larvae in raw or insufficiently cooked snails, slugs, freshwater prawns, frogs, or fish. Infection may also occur by consumption of fresh produce such as contaminated lettuce. When the larvae are ingested, they penetrate the intestinal tract, go into blood vessels, and eventually reach the meninges (the covering of the brain and spinal cord). The larvae usually die there shortly thereafter. An eosinophilic reaction develops in response to the dying larvae. It is manifested by an outpouring of eosinophils in the CSF.
