Occipitocervical fusion for reduction of traumatic periodontoid hypertrophic cicatrix. Case report.

Periodontoid hypertrophic cicatrix resulting from trauma, as demonstrated by magnetic resonance (MR) imaging, is essentially the same as that seen in rheumatoid arthritis. Recent reports suggest that, in rheumatoid arthritis, occipitocervical fusion without transoral decompression of the pannus is adequate for resolution of this anterior lesion. A case of traumatic periodontoid cicatrix is presented in which posterior fusion resulted in reduction of the anterior mass lesion, clearly demonstrated by MR imaging. The etiology of periodontoid hypertrophic scarring, both traumatic and rheumatoid, is discussed in light of MR findings, and treatment implications are considered.

[Protocol for the treatment of hypertrophic cicatrix with silastic gel. First results].

Functional limitation and scarring use to be common sequelaes of a burns injury in children. We report our initial experience with silicone gel (silastic gel shetting) in the treatment of 15 children with hypertrophic scars, without success to other alternatives therapies. Improvements in texture, colour and height of the lesion were noted in all cases.

Resolution of traumatic hypertrophic periodontoid cicatrix after posterior cervical fusion: case report.

The case of a 38-year-old man with delayed myelopathy 19 years after a nontreated odontoid type II fracture is reported. Magnetic resonance imaging of the craniocervical region revealed a periodontoid cicatrix. The clinical syndrome improved, and complete resolution of the retro-odontoid mass was achieved 9 months after posterior cervical fixation. The implications of this unique case for the management of myelopathy associated with nonunion of odontoid fractures are discussed.

[Current problems in the pathology of burns].

+The results obtained from the study on thermal trauma were summarised on the base of histological, electron microscopic, immunologic and toxicological investigation methods. Shock during burning induces disturbances in the microcirculation. The great clinical significance of the alterations in lungs are stressed upon, manifested in a disorder of blood-gas barrier, permeability of the membranes of capillaries and cells, leading to acute pulmonary insufficiency. One of the probable mechanisms of anemia advancing after burns is described, that is due to the toxic effect of serum. Complement-fixation antibodies are found in the patients with burns, suggesting the involvement of autoimmune mechanisms in the course of the disease. The disturbed microcirculation has an unfavourable effect on the regeneration of wounds, leading to destruction of epithelial regeneration, disturbing the processes of revascularization of skin transplant, having an effect on the immune reactions of organism. Sepsis is discussed, with particular attention paid to that induced by Pseudomonas aeruginosa. In would cachexia some changes in the wounds are pointed to as well as sclerotic and atrophic processes in some internal organs, being usually irreversible. The reversibility if sclerosis in hypertrophic cicatrix and keloid is discussed, stressing on the cellular and extracellular mechanisms, involved in that process.

[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 increased proportion of beta-chains in the younger hypertrophic scars approximated to the same level as in normal skin within 7 years after lesion. There was no decrease in the ratio dimers/monomers of collagen type I with age of keloid scar tissue. The relative amount of collagen type III in young keloid scars was found decreased as compared to age-matched hypertrophic scars (13 +/- 3 and 17 +/- 7 respectively), but was similar in the older scars. The average pyridinoline crosslinks content per mole of collagen in keloids was 2 times as high as in hypertrophic scars. The data support the suggestion that general, as well as peculiar disturbances of collagen metabolism are involved in the development of keloids and hypertrophic scars.
