Eczema (ekzema) - a disease of the superficial layers of the skin, accompanied by polymorphism of rashes. All farm animals, as well as dogs and cats suffer from eczema.
Etiology. Exogenous causes include mechanical (cracks, scratching), physical (the effect of high temperature and direct sunlight, in sheep - after shearing), chemical (the effect of medicinal substances, the content of animals on dirty litter). Endogenous causes are a disease of internal organs (liver, lung, gastrointestinal tract), impaired secretion of the endocrine glands, feed intoxication, ingestion of various allergens.
Clinical signs. In a typical course, the disease goes through seven stages of development: erytomatosis, a sharp reddening of unpigmented skin; papular - limited skin dense eminence, not disappearing when pressed with a finger; vesicular - the appearance of vesicles (vesicles) with serous contents; pustular - the appearance of small ulcers (pustules) formed during infection of the vesicles; weeping - spontaneous opening of pustules, effusion of exudate and gluing hair; cortical - drying of the exudate and the formation of various color crusts; scaly - rejection of the dried stratum corneum, the appearance of scales. It should be noted that a strict sequence of the above stages of the eczematous process is not required.
Local changes in the eczematous area are usually accompanied by itching.
In cattle and horses, eczema most often affects the skin in the finger, withers, back, abdomen, and in dogs in the back, tail, auricle and head.
Treatment. It is necessary to eliminate the cause of the disease. In acute eczema in the stages of blistering, pustules, moist eczema, astringent solutions are used: 3-4% - 5% - pyoctanine, methylene blue; 2% - silver nitrate; 3-5% - picric acid. Hydrocortisone intramuscularly and prednisone orally have a good therapeutic efficacy in erythematous, papular, vesicular eczema. Topically applied hydrocortisone and prednisone ointment. For near-earth eczema, antibiotic ointments, emulsions of syntomycin, streptocide, Novocain-chlortetracycline ointment (Novocain - 5 g, chlortetracycline - 5 g, petroleum jelly - 90 g) are used. The general treatment for eczema is intravenous administration of novocaine (1 ml of 0.25% solution per 1 kg of animal weight), 10% solution of potassium bromide (80-100 ml per injection for cattle and horses), 10% a solution of calcium chloride (100-150 ml per injection for horses and cattle). They also recommend autohemotherapy, diphenhydramine, multivitamins, as well as reinfusion of autologous blood irradiated with ultraviolet rays.
