encephalomyelitis

[en¦sef·ə·lō‚mī·ə′līd·əs] (medicine) Inflammation of the brain and spinal cord.

Encephalomyelitis

 

inflammation of the brain and spinal cord as a result of infection by neurotropic viruses (acute disseminated encephalomyelitis) or as a complication of other infectious diseases, for example, measles, chicken pox, or rubella. Some cases of encephalomyelitis develop after vaccination against rabies, smallpox, and certain other diseases (postvaccinal encephalomyelitis). The inflammation may also involve the cerebrospinal roots and the peripheral nerves (encephalomyelopolyradiculoneuritis), the optic nerve or other cranial nerves (neuromyelitis optica), and the meninges (meningoencephalomyelitis).

The course of encephalomyelitis is most often acute. Symptoms include elevated body temperature, muscle pain, and various neurological symptoms (paralysis, disruption of sensitivity and motor coordination). Severe cases are marked by trophic disturbances (bedsores) and sepsis. After the acute stage, there may be residual symptoms, including paresis and disturbances of sensitivity. Treatment of encephalomyelitis is the same as for encephalitis. (See.)

Encephalomyelitis

 

an enzootic viral disease of fur-bearing animals and swine in which the central nervous system is infected. Primarily young animals are affected. The disease occurs among fur-bearing animals in the USA and has been registered in the USSR. Teschen disease (porcine encephalomyelitis) afflicts swine in Central and Western Europe.

The causative agent of encephalomyelitis in fur-bearing animals is a neurotrophic virus; that of Teschen disease is an RNA-containing virus. Young animals are more susceptible to the disease than adults. Among fur-bearing animals, those that are afflicted include the young of foxes, including arctic foxes, and sables. Among swine, it is mainly sucklings, weaned piglets, and young being fattened that are affected.

The causative agents of the disease are introduced into the environment primarily with the saliva and nasal mucus of sick animals; in swine, it is also introduced with the feces and other excretions. Fur-bearing animals become infected through the breathing passages, while swine are infected through the respiratory and digestive tracts. The basic symptoms of the disease in fur-bearing animals include an unsteady walk, falling, convulsive attacks, the appearance of foam on the lips, and the transition from anxiety to the depressed state.

If the infection is acute, the animal dies in three to four days. Less acute cases are accompanied by a loss of appetite and diarrhea, sometimes with discharge of blood. In symptomless cases there may be abortions or the birth of nonviable young. In swine the stage of anxiety is followed by the paralysis of the extremities and of many groups of muscles. In acute cases up to 90 percent of the sick animals die; in subacute cases, up to 40 percent; and in chronic cases, up to 20 percent.

The treatment of fur bearing animals has little effect. No successful means of treating swine has been developed. In order to avoid spreading of encephalomyelitis to fur farms, animals arriving there are quarantined for one month; at swine farms the animals are inoculated with a live virus culture vaccine. When cases of the disease are discovered, and when the course of the disease is subacute, fur-bearing animals are isolated and treated with hyperimmune serum. During the winter they are slaughtered for fur. When cases of the disease are discovered in swine the entire herd is slaughtered. The meat of animals that are suspected to have the disease is processed for canning or for boiled sausage. The carcasses of sick swine or the wastes from slaughter are destroyed.

encephalomyelitis

 [en-sef″ah-lo-mi″ĕ-li´tis] inflammation of the brain and spinal cord.acute disseminated encephalomyelitis an acute or subacute encephalomyelitis or myelitis occurring most commonly following an acute viral infection, especially measles, but sometimes occurring without a recognizable antecedent. Clinical manifestations include fever, headache, vomiting, and drowsiness progressing to lethargy and coma; tremor, seizures, and paralysis may also occur. Mortality ranges from 5 to 20 per cent, and many survivors have residual neurologic deficits.benign myalgic encephalomyelitis chronic fatigue syndrome.equine encephalomyelitis a type of encephalomyelitis in horses and mules, caused by an alphavirus and spread to humans by mosquitoes; it occurs in summer epizootics in the Western Hemisphere. Three forms are recognized: eastern, western, and Venezuelan. Called also equine encephalitis.equine encephalomyelitis, eastern a viral disease similar to western equine encephalomyelitis, but occurring in a region extending from New Hampshire to Texas and as far west as Wisconsin, and in Canada, Mexico, the Caribbean, and parts of Central and South America.equine encephalomyelitis, Venezuelan a viral disease of horses and mules, transmissible to humans; the causative agent was first isolated in Venezuela. The infection in humans resembles influenza, with little or no indication of nervous system involvement.equine encephalomyelitis, western a viral disease of horses and mules, communicable to humans, occurring chiefly as a meningoencephalitis with little involvement of the medulla oblongata or spinal cord; observed in the United States chiefly west of the Mississippi River.granulomatous encephalomyelitis a disease marked by granulomas and necrosis of the walls of the cerebral and spinal ventricles.postinfectious encephalomyelitis (postvaccinal encephalomyelitis) acute disseminated encephalomyelitis.

encephalomyelitis

Inflammation of the brain (ENCEPHALITIS) and spinal cord (MYELITIS). Acute demyelinating encephalomyelitis may follow minor infectious diseases or vaccination and cause widespread loss of the myelin sheath of nerve fibres with paralysis, seizures and coma. The condition known as ‘ME’ (myalgic encephalomyelitis) is not a brain inflammation.
