[Comparative study of collagen in hypertrophic and keloid cicatrix].

The relative percentage of type III to type I collagen, the ratio of alpha 1(I) to alpha 2(I) collagen chains and the ratio of dimers (beta-chains) to monomers (alpha-chains) in type I collagen have been measured in solubilized collagen fractions from keloids and hypertrophic scars aged about 1-7 years after burn. In tissue samples the content of crosslink with structure of pyridinoline were analyzed and expressed as mole of crosslink per mole of collagen. A comparison between hypertrophic and keloid scars has shown that the young (about 1 year) hypertrophic scars have higher ratios alpha 1(I)/alpha 2(I) and beta 11 + beta 12/alpha 1(I) + alpha 2(I).

[The surgical treatment of contractures and syndactyly in a child with epidermolysis bullosa without using autotransplantation].

An operation was performed in an 8-years-old girl suffering from a recessive dystrophic epidermolysis bullosa from birth complicated by a developed contracture and syndactyly of the both bones in order to eliminate these defects without using an autotransplant. The postoperative course was without complications, epithelialization developed by the end of the 3rd week. No recurrences were noted during 2 years.

[The structure of fatality in burn disease in children].

On the basis of expert estimation of 208 case records of the children, who died from thermal trauma, the structure and causes of lethality in burn shock, toxemia and septicotoxemia were studied. The organization and therapeutico-diagnostic errors were analysed. The concept of "critical burn" was defined for the children of different age.
