As acute burn patients have experienced increasing survival rates, the number of patients who need specific care due to aberrant scarring is also increasing. The burned skin often responds with fibrotic tissue proliferation, which can lead to a hypertrophic scar or a keloid. Non-physiologic scars are mostly not acceptable for the burn patient. Intradermal and topical therapy in burns comprise the treatment of the skin injury and its possible texture, elasticity and color alterations with the aid of active substances that result in fibroblastic modulation. An alteration of cytokine levels may mediate these effects, and evidences suggest that keloid scar formation may be mediated, in part, by deranged growth factor activity, including that of transforming growth factor (TGF)-beta(1). The addition of tamoxifen, a non-steroidal anti-estrogen, usually used in breast cancer, to standard treatment may lead to improved wound healing in keloids by decreasing the expression of TGF-beta(1), with the consequent inhibitions of both fibroblast proliferation and collagen production. Topical tamoxifen citrate chemical treatment has been shown to improve scarring. However, prospective studies must be undertaken to validate the inclusion of tamoxifen into standard clinical practice.

Life-expectancy increased in patients infected with HIV/AIDS with the advent of highly active antiretroviral therapy (ART). Facial lipoatrophy is a common complication in these patients, eventually leading to stigma, segregation and a negative impact in quality of life (QOL). We measured the impact of the treatment of facial lipoatrophy with polymethyl methacrylate (PMMA) in the QOL of patients with HIV/AIDS by using four questionnaires that address QOL. Forty consecutive patients on ART referred for facial lipoatrophy treatment were enrolled in this study. The first 20 were allocated to the intervention group and were treated with tissue augmentation with PMMA. The other 20 were allocated to the control group, which received treatment only after six months. At baseline, four questionnaires were applied to all patients in both groups and again after six months. The variation in scores within the control group for all domains of all four instruments was significantly better when compared with that within the control group. We detected improvement in the QOL of patients with HIV/AIDS and facial lipoatrophy when they were treated with PMMA.
