  • Kelo-Cote FAQ's(PDF)
    FAQ’s What is the skin and what are its different layers? The skin is the outer covering of the body comprised of three layers, the protective layer (epidermis), the thicker middle layer which contains support structures such as blood vessels, nerves, sweat glands and hair follicles (dermis), and an inner layer that contains larger blood vessels and fatty tissue (subcutaneous). What is the function of the skin? The skin is the largest organ of the body and comprises approximately 15% of total body weight. It protects the body from infection, radiation from the sun and exhales gasses produced by the normal function of the body. It prevents excessive water loss, helps regulate body temperature (as it is gas- permeable) and protects the internal organs. What is Kelo-cote®? Kelo-cote ® is a lightweight, self-drying silicone gel for the treatment of scars. Kelo-cote ® has been shown to flatten, soften and smooth scars, relieve the itching and discomfort of scars, as well as reduce the discoloration associated with scars. What is Kelo-cote® made of? Kelo-cote ® is a patented proprietary formula containing bio-inert and bio-compatible silicone compounds, namely polysiloxane, silicone dioxide and non-volatile silicone components. It is therefore intended for the use on children or people with sensitive skin. How does Kelo-cote® work? Kelo-cote ® rapidly dries to form a sheet; this silicone gel sheet layer is gas permeable, flexible and waterproof. Kelo-cote ® forms a bond with the stratum corneum (the outer layer of dead skin cells) forming a protective barrier against chemical, physical and microbial invasion of the scar site while assisting with hydration.

    Cigna National Formulary Coverage Policy Prior Authorization Topical Retinoids – Tazarotene Products Table of Contents Product Identifier(s) National Formulary Medical Necessity ................ 1 01541 Conditions Not Covered....................................... 2 Background .......................................................... 2 References .......................................................... 2 Revision History ................................................... 3 INSTRUCTIONS FOR USE The following Coverage Policy applies to health benefit plans administered by Cigna Companies. Certain Cigna Companies and/or lines of business only provide utilization review services to clients and do not make coverage determinations. References to standard benefit plan language and coverage determinations do not apply to those clients. Coverage Policies are intended to provide guidance in interpreting certain standard benefit plans administered by Cigna Companies. Please note, the terms of a customer’s particular benefit plan document [Group Service Agreement, Evidence of Coverage, Certificate of Coverage, Summary Plan Description (SPD) or similar plan document] may differ significantly from the standard benefit plans upon which these Coverage Policies are based. For example, a customer’s benefit plan document may contain a specific exclusion related to a topic addressed in a Coverage Policy. In the event of a conflict, a customer’s benefit plan document always supersedes the information in the Coverage Policies. In the absence of a controlling federal or state coverage mandate, benefits are ultimately determined by the terms of the applicable benefit plan document. Coverage determinations in each specific instance require consideration of 1) the terms of the applicable benefit plan document in effect on the date of service; 2) any applicable laws/regulations; 3) any relevant collateral source materials including Coverage Policies and; 4) the specific facts of the particular situation.

  • A Review of the Evidence for and Against a Role for Mast Cells in Cutaneous Scarring and Fibrosis

Wilgus 1,*, Sara Ud-Din 2 and Ardeshir Bayat 2,3 1 Department of Pathology, Ohio State University, Columbus, OH 43210, USA 2 Centre for Dermatology Research, NIHR Manchester Biomedical Research Centre, Plastic and Reconstructive Surgery Research, University of Manchester, Manchester M13 9PT, UK; [email protected] (S.U.-D.); [email protected] (A.B.) 3 MRC-SA Wound Healing Unit, Division of Dermatology, University of Cape Town, Observatory, Cape Town 7945, South Africa * Correspondence: [email protected]; Tel.: +1-614-366-8526 Received: 1 October 2020; Accepted: 12 December 2020; Published: 18 December 2020 Abstract: Scars are generated in mature skin as a result of the normal repair process, but the replacement of normal tissue with scar tissue can lead to biomechanical and functional deficiencies in the skin as well as psychological and social issues for patients that negatively affect quality of life. Abnormal scars, such as hypertrophic scars and keloids, and cutaneous fibrosis that develops in diseases such as systemic sclerosis and graft-versus-host disease can be even more challenging for patients. There is a large body of literature suggesting that inflammation promotes the deposition of scar tissue by fibroblasts. Mast cells represent one inflammatory cell type in particular that has been implicated in skin scarring and fibrosis. Most published studies in this area support a pro-fibrotic role for mast cells in the skin, as many mast cell-derived mediators stimulate fibroblast activity and studies generally indicate higher numbers of mast cells and/or mast cell activation in scars and fibrotic skin.

Painful vs. painless? Pruritic? Burning sensation? Key descriptive elements – 1- definition and morphology of the lesion, 2- location and the extent of the disease. DEFINITIONS: Atrophy: Thinning of the epidermis and/or dermis causing a shiny appearance or fine wrinkling and/or depression of the skin (common causes: steroids, sudden weight gain, “stretch marks”) Bulla: Circumscribed superficial collection of fluid below or within the epidermis > 5mm (if <5mm vesicle), may be formed by the coalescence of vesicles (blister) Burrow: A linear, “threadlike” elevation of the skin, typically a few millimeters long. (scabies) Comedo: A plugged sebaceous follicle, such as closed (whitehead) & open comedones (blackhead) in acne Crust: Dried residue of serum, blood or pus (scab) Cyst: A circumscribed, usually slightly compressible, round, walled lesion, below the epidermis, may be filled with fluid or semi-solid material (sebaceous cyst, cystic acne) Dermatitis: nonspecific term for inflammation of the skin (many possible causes); may be a specific condition, e.g. atopic dermatitis Eczema: a generic term for acute or chronic inflammatory conditions of the skin.
