important endogenous anti-fibrotic defense mechanism. Troglitazone, a PPAR-γ agonist, has been used to suppress the formation of keloids and growth of hypertrophic scar fibroblasts. Indeed, the PPAR-γ agonist was able to inhibit collagen I expression in hypertrophic scar fibroblasts, which clearly demonstrates its therapeutic potential, and clarification of the underlying molecular mechanisms c...

BACKGROUND Hypertrophic scarring caused by sternotomy is prevalent among Asians. The effectiveness of silicone gel in scar prevention may influence the decision of surgeons and patients regarding its routine use during the postoperative period. METHODS The authors conducted a randomized, placebo-controlled, double-blind, prospective clinical trial. The susceptibility to scar development varie...

Management of incisional scar is intimately connected to stages of wound healing. The management of an elective surgery patient begins with a thorough informed consent process in which the patient is made aware of personal and clinical circumstances that cannot be modified, such as age, ethnicity, and previous history of hypertrophic scars. In scar prevention, the single most important modifiab...

BACKGROUND Abnormal (keloid and hypertrophic) scars are a significant affliction with no satisfactory single modality therapy to-date. Available options are often ineffective, painful, potentially hazardous, and require healthcare personnel involvement. Herein a self-administered microneedle device based on drug-free physical contact for inhibiting abnormal scars is reported. Its therapeutic ac...

BACKGROUND To study the effect of abnormal savda munziq (ASMq) on TGF-β1 and Smad7 expression in hypertrophic scar fibroblasts (HSFs) and to preliminarily assess the function of abnormal savda munziq in hypertrophic scar formation at the molecular biology level. METHODS HSFs were cultured in vitro. RT-PCR and Western-blot were used to investigate the influence of 48-h treatment with ASMq at d...

BACKGROUND Hypertrophic scars are one of the most important complications in surgery due to their cosmetic and functional impairments. Previous studies in tissue fibrotic disorders have shown promising results by inhibiting the biological activity effect of Transforming Growth Factor-beta 1 (TGF-β1). The aim of the current study was to determine the clinical effect of the inhibition of TGF-β1 s...

Scars are problematic for thousands of patients. Scarring is a natural part of the healing process after an injury. However, the appearance of a scar and its treatment depend on multiple factors and on the experience of the therapist and the options available. Despite a plethora of rapidly evolving treatment options and technical advances, the management of atrophic and hypertrophic scars remai...

BACKGROUND Hypertrophic scars and keloids are associated with abnormal levels of growth factors. Silicone gel sheets are effective in treating and preventing hypertrophic scars and keloids. There has been no report on the change in growth factors in the scar tissue following the use of silicone gel sheeting for scar prevention. A prospective controlled trial was performed to evaluate whether gr...
