Epigenetic Influences on Wound Healing and Hypertrophic-Keloid Scarring: A Review for Basic Scientists and Clinicians.

Cureus 2022 Mar 26;14(3):e23503. Epub 2022 Mar 26.

Pathophysiology, American University of Antigua, Coolidge, ATG.

Primary care physicians and dermatologists are challenged by patients affected by keloid or hypertrophic scarring resulting from accidental wounding, surgical incisions, tattooing, or "branding" procedures to demonstrate their association with a specific culture, fraternity, or cult. The dysregulated wound healing associated with keloids and hypertrophic scarring adversely affects genetically susceptible individuals, especially persons of color with Fitzpatrick Skin types IV-VI. Although the specific mechanisms of bulky hypertrophic/keloid scarring and its association with oxidative stress and inflammation remain unclear, the current knowledge base is sufficient to provide some guidance to health practitioners who must serve, treat, and counsel affected individuals.

The use of fluid silicone gels in the prevention and treatment of hypertrophic scars: a systematic review and meta-analysis.

Burns 2022 May 17;48(3):491-509. Epub 2022 Mar 17.

Burn Center, Ghent University Hospital, C. Heymanslaan 10, 9000 Ghent, Belgium; Department of Plastic Surgery, Ghent University Hospital, C. Heymanslaan 10, 9000 Ghent, Belgium.

Schwann cells contribute to keloid formation.

Matrix Biol 2022 04 10;108:55-76. Epub 2022 Mar 10.

Department of Dermatology, Medical University of Vienna, Vienna, Austria. Electronic address:

Keloids are disfiguring, hypertrophic scars with yet poorly understood pathomechanisms, which could lead to severe functional impairments. Here we analyzed the characteristics of keloidal cells by single cell sequencing and discovered the presence of an abundant population of Schwann cells that persisted in the hypertrophic scar tissue after wound healing. In contrast to normal skin, keloidal Schwann cells show a unique, pro-fibrotic phenotype. Read More

Downregulated cytotoxic CD8 T-cell identifies with the NKG2A-soluble HLA-E axis as a predictive biomarker and potential therapeutic target in keloids.

Cell Mol Immunol 2022 Apr 17;19(4):527-539. Epub 2022 Jan 17.

Department of Plastic and Reconstructive Surgery, Ninth People's Hospital, Shanghai Jiao Tong University School of Medicine, Shanghai, China.

Keloids are an abnormal fibroproliferative wound-healing disease with a poorly understood pathogenesis, making it difficult to predict and prevent this disease in clinical settings. Identifying disease-specific signatures at the molecular and cellular levels in both the blood circulation and primary lesions is urgently needed to develop novel biomarkers for risk assessment and therapeutic targets for recurrence-free treatment. There is mounting evidence of immune cell dysregulation in keloid scarring. Read More

Plasma Radiofrequency Ablation for Scar Treatment.

J Clin Med 2021 Dec 27;11(1). Epub 2021 Dec 27.

Plastic Surgery Unit, University of Campania "Luigi Vanvitelli", 80120 Napoli, Italy.

Scars are a common disfiguring sequela of various events such as acne, hidradenitis suppurativa, surgery, trauma, and burns, which can lead to serious psychosocial problems with a negative effect on the quality of life. Many conventional approaches have been proposed for the treatment of scars, including surgical techniques, dermabrasion, chemical peels, topical silicone gel, 5-fluorouracile and dermal fillers injection or autologous fat transfer for atrophic scars, and corticosteroids injection for hypertrophic and keloid scars; however, they have sporadic effects. Ablative lasers, such as carbon dioxide laser or Erbium Yag laser, are associated with many collateral effects limiting their application. Read More

Plastic & Reconstructive Surgery Research, Centre for Dermatology Research, Wound Healing Theme, NIHR Manchester Biomedical Research Centre, University of Manchester, Manchester, England, United Kingdom.

The cutaneous repair process naturally results in different types of scarring that are classified as normal or pathological. Affected individuals are often affected from an esthetic, physical (functional), and psychosocial perspective. The distinct nature of scarring in humans, particularly the formation of pathological scars, makes the study of skin scarring a challenge for researchers in this area. Read More

Department of Dermatology, The First Affiliated Hospital of Nanjing Medical University, Nanjing, 210029, China.

Though widely used to assess pathological scars, the modified Vancouver Scar Scale (mVSS) is neither convenient nor objective. Shear wave elastography (SWE) is used to evaluate the stiffness of pathological scars. We aimed to determine the correlation between mVSS score and elastic modulus (EM) measured by SWE for pathological scars. Read More

Molecular Features of Hypertrophic Scars After Thermal Injury: Is There a Biologic Basis for Laser Therapy?

Adv Wound Care (New Rochelle) 2022 04 22;11(4):163-178. Epub 2021 Dec 22.

Wound Healing Research Group, Division of Plastic and Reconstructive Surgery, Department of Surgery, University of Alberta, Edmonton, Canada.

Hypertrophic scars (HTS) and keloids are common after thermal injuries and other trauma to deep regions of dermis of the skin. These abnormal scars can cause contractures and the thick masses of scar tissue that result in functional and cosmetic impairment. Management of these dermal fibrotic conditions includes a wide range of medical and surgical treatments, which can be time consuming, only partially effective, and often uncomfortable for patients.
