Radiation myelitis

In general practice, myelitis and myelopathy are considered synonymous, and during a random search in the electronic database of scientific medical publications, errors in the understanding of the author are possible. Currently, it is necessary to distinguish two diseases of different origin: radiation myelopathy and radial myelitis, and try to differentiate in written studies

Myelitis of the radial nerve is an inflammatory process of the spinal roots, which occurs due to the direct effect of radiation radiation. The disease has many synonyms (radiation myelosis, radiation myopathy), which proves its relevance and prevalence among the population.

**Pathogenesis** Myelitis can occur as a complication of inflammatory processes in the respiratory system or with brain tumors. In men, the disease is more common after receiving a dose of radiation due to ionizing radiation, and in women - as a result of chemotherapy.

Symptoms appear several days after exposure to radiation and are particularly acute. Patients experience numbness, muscle weakness, convulsions, paralysis of the limbs and speech impairment. Moreover, the intensity of the manifestations of myelitis symptoms does not depend on the dose of x-ray radiation. In addition, patients often complain of intense headaches accompanied by nausea and vomiting.

Myelitis of the wrist joint (MR) is an acute inflammation of the spinal cord in the area of ​​the osteo-fibrous canal in the area of ​​the root of the arch of the wrist, accompanied by severe muscular-articular syndrome. In most cases of MR myelitis, lesions are observed in people of young working age (up to 35-40 years), predominantly men.

The nervous system is one of the first, most sensitive systems of the human body to the action of harmful substances (radioactive, chemical and physical). In addition, due to the possibility of contamination (penetration) of radioactive substances through the skin when working with radioactive substances and radiation diagnostic methods, myelitis is a contagious disease. Half of those who die from myelitis occur due to the unfavorable development of acute radiation injury when the effective dose to the body surface exceeds 8-10 Crem. Such an excess is possible when using x-ray radiation in practice in high-energy rays (220-280 square meters), which are currently allowed only for preventive, medical, scientific and control research. Theater workers who use infrared film projection, which has not yet been abandoned in the production of film copies for home exhibition, often die. The widespread film storage of devices such as “Ftava” and “Slavyanin” does not meet modern radio safety requirements. Electromagnetic fields of low frequencies, which are the background of radio and television transmitting equipment, cause symptoms typical of myelitis: descending central paresis with fibrillar twitching of the muscles of the forearm, dysfunction of the joints, trophic disorders - pastiness of the distal limbs, aging of the skin, senile flow of hair, headaches pain. Symptoms of MR resemble those of polyradiculoneuritis, but differ from them in their earlier onset (at 2 and 3 weeks
