Ephelides
Ephelides The plural of ephelis, a type of freckle. Ephelis and ephelides are among the many medical terms that are rarely, if ever, encountered outside of medicine.
RELATED TERMS--------------------------------------
Ephelis
A form of freckle. A flat red or light-brown spot on the skin that typically appears during the sunny months and fades in the winter. They are most often found in people with light complexions and in some families, they are an hereditary (genetic) trait. The regular use of sunscreen during times of sun exposure helps to suppress the appearance of the ephelis-type freckle.
Freckle
A flat circular spot on the skin about the size of the head of a nail that develops after repeated exposure to sunlight, particularly in someone of fair complexion. Freckles may be red, yellow, tan, light-brown, brown, or black. They are always darker than the skin around them since they are due to deposits of the dark melanin, a dark pigment.

Enzymes, yellow
A group of respiratory enzymes that catalyze reactions in the body permitting cells to respire or breathe. These biochemical reactions are termed oxidation-reduction reactions.
EOG
Electro-oculography. A type of electrophysiologic retinal testing.
EOS
The gene for familial eosinophilia. EOS has been mapped to chromosome region 5q31-33 containing the cytokine gene cluster which includes the genes for interleukin-3 (IL-3), interleukin-5 (IL-5), and granulocyte colony-stimulating factor (G-CSF), and all of which are thought play roles in the development, proliferation, and activation of 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).
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.

Epicanthal fold
A fold of skin that comes down across the inner angle (canthus) of the eye. The epicanthal fold is more common in children with Down syndrome and other birth defects than normal children and so is of value in diagnosis. Although some dictionaries state that this eye fold is found in peoples of Asian origin, this is not true. The normal Asian eyefold is continuous with the lower edge of the upper eyelid and actually appears distinctly different than a true epicanthal fold.
Epidemic
The occurrence of more cases of a disease than would be expected in a community or region during a given time period. A sudden severe outbreak of a disease such as SARS.
Epidemic hemorrhagic fever
A number of diseases characterized by an abrupt onset of high fever and chills, headache, cold and cough, and pain in the muscles, joints and abdomen with nausea and vomiting followed by bleeding into the kidney and elsewhere. Known also as hemorrhagic fever with renal syndrome. Many arboviruses (including those in the families Togaviridae, Flaviviridae, Filoviridae, and Bunyaviridae) and the Hantaviruses, spread by rodents or biting insects, can cause epidemic hemorrhagic fever. The Ebola virus is a notorious cause of epidemic hemorrhagic fever.
Epidemic myalgia
Also known as Bornholm disease, this is a temporary illness that is a result of virus infection. The disease features fever and intense abdominal and chest pains with headache. The chest pain is typically worsened by breathing or coughing. The illness usually lasts from 3 to 14 days. The most common virus causing Bornholm disease is an enterovirus called Coxsackie B. Bornholm disease is also called pleurodynia (because of inflammation of the lining tissue of the lungs).
