Background: Hypertrophic scars frequently follow primary closure of surgical wounds. Laser application at or shortly after suture may be associated with a reduction in scar formation, although the respective study results vary.
Aim: The objective was to evaluate the efficacy of early laser applied within the first six months after surgery to reduce scar formation compared to no treatment.
Methods: We searched the databases MEDLINE and CENTRAL on 14 January 2019 and included randomized controlled trials (RCTs). Primary outcome was the Vancouver Scar Scale (VSS). Measure of treatment effect was the mean difference from baseline.
Results: Seventeen relevant RCTs randomized 430 scars (413 assessed) and compared laser versus no treatment. Fourteen studies applied a split-scar and three applied a simple parallel design. Three studies with a split-scar design favored the laser group on VSS, and one study had indifferent findings. Considerable heterogeneity I = 86% did not justify a meta-analysis. The remaining 13 studies did not report appropriate data.
Conclusion: On the basis of the currently available evidence, we are uncertain whether early laser can reduce scar formation, and more high-quality research is needed for a definitive conclusion.

Burn care and treatment differ markedly from other types of wounds, as they are significantly more prone to infections and struggle to maintain fluid balance post-burn. Moreover, the limited self-healing abilities exacerbate the likelihood of scar formation, further complicating the recovery process. To tackle these issues, an asymmetric wound dressing comprising a quercetin-loaded poly(3-hydroxybutyrate-co-4-hydroxybutyrate) (P34HB@Qu) hydrophilic layer and a zinc oxide nanoparticle-loaded, thermally treated polyvinylidene fluoride (HPVDF@ZnO) hydrophobic layer is designed.

Wear particle reaction is present in every arthroplasty. Sometimes, this reaction may lead to formation of large pseudotumors. As illustrated in this case, the volume of the reaction may be out of proportion to the volume of the wear scar.

Disruption of the molecular pathways during physiological wound healing can lead to raised scar formation, characterized by rigid, thick scar tissue with associated symptoms of pain and pruritus. A key mechanical factor in raised scar development is excessive tension at the wound site. Recently, microneedles (MNs) have emerged as promising tools for scar management as they engage with scar tissue and provide them with mechanical off-loading from both internal and external sources.

Skin and soft tissue infections (SSTI) include bacterial infections of the skin, muscles, and connective tissue such as ligaments and tendons. SSTI in patients with immunocompromising diseases may lead to chronic, hard-to-heal infected wounds, resulting in disability, amputation, or even death. To treat SSTI and rebuild the defensive barrier of the skin, here we utilize recombinant type XVII collagen protein (rCol XVII) to construct biodegradable, regenerative collagen microneedles (rCol-MN) for transdermal delivery of antibacterial agents.

Tissue engineering utilizing hydrogel scaffolds in combination with exogenous stem cells holds significant potential for promoting wound regeneration. However, the microenvironment provided by existing skin tissue engineering scaffold materials is often inadequate. Herein, we demonstrate an enzyme-crosslinked hyaluronic acid hydrogel to provide a growth microenvironment for exogenous bone marrow mesenchymal stem cells and promote acute wound healing.
