Abstract:
Serious skin injuries can lead to the formation of scars, in particular hypertrophic and keloid scars. The prevalence of keloids and hypertrophic scars varies among different populations. Scar formation is a natural process during wound healing, but when keloid scars form, regeneration is impaired. It is generally accepted that a keloid scar is formed as a result of increased synthesis of collagen and extracellular matrix against the background of reduced degradation of these products. Clinically, keloid and hypertrophic scars have a number of differences. Thus, the formation of a keloid scar

Abstract Introduction Hypertrophic scars are seen in 70% of individuals after a burn. Survival from acute burns have psychosocial and functional challenges. Hypertrophic scars contain disorganized whorls of collagen, an increase in occluded blood vessels resulting in raised discoloration, inflamed dermis/epidermis and painful sequelae. Management of such scars have been limited to invasive and non-invasive management. One innovative technology is a non-invasive high-intensity laser operating at 1275 nm and 74 Watts, optimizing increased depth of penetration into the tissue utilizing photomecha

Background: Conservative treatment of deep dermal or full-thickness skin defects often results in hypertrophic scars or contractures; thus, compressive therapy has been used after wound closure to prevent or treat scar deformities.

We therefore attempted early compression therapy as a means of conservative treatment of deep-skin defects and evaluated its clinical outcomes. Methods: In 21 cases of deep skin defects (19 patients), early compressive therapy was started the second week after injury. Saline-

Abstract:
Introduction: Postoperative management following primary cleft lip repair varies across institutions, cleft care teams, and individual surgeons. Postoperative precautions employed after cleft lip repair include dietary restrictions, pacifier limitations, and immobilization, with arm restraints long being used. Yet, restraint distress has led to the exploration of other forms of immobilization. Thus, this study aims to assess cleft lip scar quality and complication rates after postoperative immobilization with arm restraints versus hand mittens.

Abstract Introduction Silicone sheets are commonly used for prevention and treatment of burn scars and silicone-based products have recently been recommended as the gold standard non-invasive treatment choice. One problem with silicone gel sheets application is that the sheets lose their adhesive qualities making them difficult to affix to the patient and costly to replace when lost. A new ultra-thin, clear and adhesive silicone gel sheet layered on a semi-permeable polyester backing was trialed at our burn center. The silicone is designed to be a one-time application, worn during all activiti

Abstract:
Wound healing is a complicated cascading process; disequilibrium among reparative processes leads to the formation of pathologic scars. Herein, we explored the role of mortalin in scar formation and its association with the interleukin-1α receptor using in vitro and in vivo models. To investigate the effects of mortalin, we performed an MTT cell viability assay, qRT-PCR, and Western blot analyses, in addition to immunofluorescence and immunoprecipitation studies using cultured fibroblasts. A rat incisional wound model was used to evaluate the effect of a mortalin-specific shRNA (dE1-RGD/GFP/sh

We have shown that astrocytes in mice deficient for both GFAP and vimentin (GFAP−/−vim−/−) cannot form IFs even when nestin is expressed and are thus devoid of IFs in their reactive state. Here, we have studied the reaction to injury in the central nervous system in GFAP−/−, vimentin−/−, or GFAP−/−vim−/− mice.

Abstract:
Deep dermal defects can result from burns, necrotizing fasciitis and severe soft tissue trauma. Physiological scar restriction during wound healing becomes increasingly relevant in proportion to the affected area. This massively restricts the general mobility of patients. External mechanical influences (activity or immobilization in everyday life) can lead to the formation of marked scar strands and adhesions. Overloading results in a renewed inflammatory reaction and thus in further restriction. Appropriate mechanical stimuli can have a positive influence on the scar tissue. “Use determines f

Secondly, large orthoses are heavy, require dexterity, are hard to sustain a long stretch and thus have decreased adherence.
