RED FLAT LICHING
RED FLAT LICHY is a skin disease characterized by itchy nodular (papular) rashes, damage to the mucous membranes of the oral cavity and external genital organs, as well as nails. More often adults are ill.
The etiology is not finally established; the virus is suspected to be the causative agent. An important role in the development of the disease is played by mental injuries, dysfunction of the autonomic nervous system, endocrine disorders, diseases of the gastrointestinal tract, etc. Foci of chronic infection and some drugs (for example, streptomycin) can have a provocative effect.
Rashes in the form of papules are usually located symmetrically on the flexion surface of the forearms, abdomen, legs, hips. Papules are dense, red-violet in color with polygonal outlines, a flat shiny surface and a slight retraction in the center. Gradually they become brown, and then brown; can merge, forming slightly scaly plaques with a diameter of up to 3 cm. On some plaques, a grayish-white mesh pattern is visible, which is better detected when lubricated with vegetable oil. The appearance of rashes is accompanied by itching, especially severe in elderly people and children. In the acute stage of the disease (during the period of the appearance of new rashes), typical papules appear in the area of skin trauma (scratches, scratches) after 7-10 days.
The defeat of the mucous membranes occurs in isolation or in combination with rashes on the skin. On the mucous membrane, rashes are localized mainly on the inner surface of the cheeks, back of the tongue, less often in the sky, red border of the lips, vulva, where small whitish papules form a lesion, sometimes resembling a fern leaf in outline. One of the forms of damage to the mucous membrane is erosive-ulcerative, characterized by a persistent course; it is observed more often in patients with diabetes mellitus and hypertension.
The affected nail plates become thinner, become dull, brittle, deform, and longitudinal scallop-like linear thickenings appear on their surface.
Treatment consists in the rehabilitation of foci of chronic infection, the elimination of neurotic, metabolic and immune disorders. Prescribe antibiotics, antihistamines (suprastin, fencarol, tavegil, etc.) and sedatives (valerian, tazepam, etc.) in combination with B vitamins, nicotinic acid. With stubborn progression of the process, glucocorticoids, methyluracil , potassium orotate are used. Locally effective corticosteroid as well as antiviral ointments (for example, riodoxol). With severe itching, the affected areas are wiped with a 2 - 5% aqueous or alcohol solution of resorcinol, a 0.1% solution of menthol with a 1% solution of chloral hydrate. The condition of patients is improved by warm baths, hypnosis, electric sleep. It is necessary to follow a diet (table No. 5) and ensure proper skin care.
