[Skin pathology from exposure to the lubricating coolant fluid MR-7]. / Kozhnaia patologiia ot vozdeistviia smazochno-okhlazhdaiushchei zhidkosti MR-7.

The article narrates on pathologic developments in the skin caused by the lubricating cooling liquid MP-7. 63 workers, including machine operators and adjusters, were medically examined, as a result of which it was established that the MP-7 liquid manifested marked irritating properties and less expressed allergenic characteristics. Oil-induced folliculitis, allergic dermatitis and eczema cases constituted 85.4 +/- 4.6% rate, which confirmed the occupational origin of the lesions. Ample supply of hygienic clothes, other hygienic procedures, weekly change of overalls did not fully eliminate contact with the MP-7 liquid.

[The effect of the working conditions on the development of diseases in cast-iron welders]. / Vliianie uslovii truda na razvitie zabolevanii u svarshchikov chuguna.

It was established that during cast-iron welding unfavourable factors of this production are welding aerosols, thermal and physical loads, radiation of the optical range. Results of detailed medical screening evidence that 80% of cast-iron welders showed pathology of the internal organs. Diseases of the bronchopulmonary apparatus occupy the leading place and are registered in every second cast-iron welder. The incidence rises with increased length of work and age.

[Skin lesions caused by exposure to a pesticide norbormid]. / Kozhnye porazheniia ot kontakta s pestitsidom norbormidom.

Norbormid used as zoocide (rodenticide) can produce an irritating and allergenic effect when acting on the skin. A case of contact dermatitis is described on a woman who poured over pesticide solution in order to make poisonous pesticides for rodents. The solution got on the skin of her hands, right crus and left forearm. There the signs of acute skin inflammation appeared along with the clinical picture of chronic dermatosis caused by the solution irritating characteristics. The degree of pesticide sensitivity was determined by means of a drop test, 1%-norbormid alcohol solution being used. Preventive measures should involve workers' obligatory instructions on norbomid zoocide noxious impact on human skin and strict observance of industrial safety rules.

[Dermatosis caused by the bites of blood-sucking insects]. / Dermatoz, Vyzvannyi ukusami krovososushchikh nasekomykh.

The present paper deals with skin lesions on the unprotected parts of the body of a 27-year-old woman which has been attacked by blood-sucking insects while staying in the Leningrad region at the end of May when the air temperature varied within 15-30 degrees C range. High biting activity of the insects resulted in the development of skin allergies. The first signs of inflammation after biting included pronounced exudative processes followed by the formation of bullous elements secreting serous fluid. Persistant time-course of epizoonosis as well as resistance to all kinds of general and local treatment resulted in the allergic contact dermatosis featuring nodular formations, especially on the skin, and solid papulous elements, accompanied by pruritus. Such persistant duration of the disease may be due, probably, to previous allergic background, resulting from her parents' allergic diseases. Identical clinical patterns of epizoonosis may be induced by the bites of various blood-suckers (sandflies, mosquitoes etc) while the human organism's response may depend upon its general state of health and immunological reactivity.
