    Wound healing is one of the most complex processes in multicellular organisms, involving numerous intra- and intercellular signalling pathways in various cell types. It involves extensive communication between the cellular constituents of diverse skin compartments and its extracellular matrix. Miscommunication during healing may have two distinct damaging consequences: the development of a chronic wound or the formation of a hypertrophic scar/keloid. Read More

    [Therapy of scars with lasers].
    Hautarzt 2018 Jan;69(1):17-26
    Skin House, Mailand, Italien.
    Scar formation is the consequence of trauma to the skin that affects the deep parts of the dermis. Different scar types like immature, mature, atrophic, hypertrophic, or keloid scars can develop depending on factors like age, anatomic localization, cause of trauma, the course of the healing process, and individual predispositions. Keloids and hypertrophic scars are often associated with itching, pain, tautness of the skin, and functional impairments, thus, leading to significantly reduced quality of life in some patients.

    Keloid and Hypertrophic Scars Are the Result of Chronic Inflammation in the Reticular Dermis.
    Int J Mol Sci 2017 Mar 10;18(3). Epub 2017 Mar 10.
    Department of Plastic, Reconstructive and Aesthetic Surgery, Nippon Medical School Hospital, Tokyo 113-8603, Japan.
    Keloids and hypertrophic scars are caused by cutaneous injury and irritation, including trauma, insect bite, burn, surgery, vaccination, skin piercing, acne, folliculitis, chicken pox, and herpes zoster infection. Notably, superficial injuries that do not reach the reticular dermis never cause keloidal and hypertrophic scarring. This suggests that these pathological scars are due to injury to this skin layer and the subsequent aberrant wound healing therein. Read More

    Am J Clin Pathol 2016 Dec;146(6):709-717
    From the Dermatopathology Unit, Pathology Service, Massachusetts General Hospital and Harvard Medical School, Boston
    Objectives: To examine Hedgehog signaling in cutaneous fibrosing disorders for which effective approved therapies are lacking, expand our knowledge of pathophysiology, and explore the rationale for targeted inhibition.

    Methods: Stain intensity and percentage of cells staining for Sonic hedgehog (Shh), Indian hedgehog (Ihh), Patched (Ptch), glycogen synthase kinase 3 β (GSK3-β), β-catenin, and Snail were evaluated in human skin biopsy specimens of keloid, hypertrophic scar (Hscar), scleroderma, nephrogenic systemic fibrosis (NSF), scar, and normal skin using a tissue microarray.

    Results: Ihh, but not Shh, was detected in a significantly larger proportion of cells for all case types. Read More

    Keloid scar, dermal benign fibro-proliferative growth that extends outside the original wound and invades adjacent dermal tissue due to extensive production of extracellular matrix, especially collagen, which caused by over expression of cytokines and growth factors. Although many attempts were made to understand the exact pathophysiology and the molecular abnormalities, the pathogenesis of keloid scar is yet to be determined. Even though there are several treatment options for keloid scars include combination of medical and surgical therapies like combination of surgical removal followed by cryotherapy or intralesional steroid therapy, the reoccurrence rate is still high despite the present treatment.

    Cnidarian envenomations are common occurrences in the tropics that can affect holidaymakers. The cutaneous reactions are classified as immediate or delayed types. Delayed allergic reactions are persistently recurring dermatitis, which can occur within 1-4 weeks from the initial sting, and may last for several months. Read More

    A Comparison of Gene Expression of Decorin and MMP13 in Hypertrophic Scars Treated With Calcium Channel Blocker, Steroid, and Interferon: A Human-Scar-Carrying Animal Model Study.

    Background: The formation of hypertrophic scaring (HSc) is an abnormal wound-healing response. In a previous study, an animal model with human scar tissue implanted into nude mice (BALB/c) has been successfully established. The effects of verapamil as well as combination therapy with verapamil and kenacort have been studied and compared. Read More
