Article Abstract
Nonlinear optical microscopy (NLOM) was applied for monitoring dermal wound healing after mesenchymal stem cell (MSC) transplantation. Our results showed that NLOM can reveal different regeneration processes of collagen in nontreated and MSC-treated wound dermis. Specifically, the temporal increases in the intensity of second-harmonic-generation signals can quantify kinetic properties of collagen regeneration. Orientation analysis of collagen fiber bundles can monitor the formation of new normal collagen fiber bundles, which is an indicator for evaluating the therapy response. It was also found that NLOM can track MSCs' location and recruitment. These findings suggested that NLOM is ideal for monitoring the progress of dermal wound healing.

Advances in Care for Burn and Hypertrophic Scar: Innovations in Prevention and Dermal Regeneration.
Ann Plast Surg
September 2025
From the Department of Plastic Surgery, Section of Surgical Sciences, Vanderbilt University Medical Center, Nashville, TN.
Hypertrophic scarring (HTS) remains a critical challenge in burn care, often resulting in debilitating contractures, chronic pain, and significant psychosocial burden. While current treatment emphasizes structural repair, recent advances underscore the importance of addressing the biological drivers of fibrosis. This review synthesizes evolving strategies in burn scar prevention, highlighting tissue-engineered matrices, autologous cell therapies, and predictive molecular tools that shift care from reactive to regenerative.

Implant extrusion is a rare but serious complication typically linked to infection, poor wound healing, or material intolerance. This case report describes a 79-year-old female patient who experienced extrusion of both a hip prosthesis and an Inspire hypoglossal nerve stimulator (Inspire Medical Systems, Inc., Minnesota, USA), each event associated with the use of Ethibond (Ethicon, Johnson & Johnson, Georgia, USA) sutures.

Introduction And Importance: Sensitivity to medical adhesives, such as Leukoplast, can lead to significant skin reactions, complicating wound management. While systemic corticosteroids are the mainstay of treatment for severe adhesive hypersensitivity, the adjunctive role of moist wound dressings in optimizing local wound healing and patient comfort remains underexplored.
Case Presentation: A 70-year-old woman with hyperthyroidism and hypertension developed blood blisters 4 h after leukoplast adhesive application during hospitalization for seizures.

Large, complex wounds frequently exhibit suboptimal healing, leading to scarring and functional impairment. While bioactive materials and electrical stimulation (ES) show promise, their individual limitations call for novel approaches. This study investigates the combined effects of combining 4-aminopyridine (4AP) and electrical stimulation (ES) on human dermal fibroblasts (hDFBs) using a stable, ionically conductive (IC) chitosan-based scaffold for controlled drug delivery.
