The RECELL Device enables a thin split‐thickness skin sample to be processed to produce a RES® Regenerative Epidermal Suspension for immediate delivery onto a prepared wound bed. The cell suspension contains a mixed population of cells, including keratinocytes, fibroblasts, and melanocytes, obtained from the disaggregation of the skin sample. The preservation of melanocytes is important for restoring natural pigmentation to the recipient area. Additionally, sub‐populations of keratinocytes critical for re‐epithelialization have been identified in RES including basal keratinocytes, suprabasal keratinocytes, and activated keratinocytes. The Enzyme used to process the cells is a biological agent and as such may have slight variations in color and texture. INDICATIONS FOR USE The RECELL Autologous Cell Harvesting Device is indicated for the treatment of acute thermal burn wounds. The RECELL Device is used by an appropriately‐licensed healthcare professional at the patient’s point of care to prepare autologous RES® Regenerative Epidermal Suspension for direct application to acute partial‐thickness thermal burn wounds in patients 18 years of age and older or application in combination with meshed autografting for acute full‐thickness thermal burn wounds in pediatric and adult patients. CONTRAINDICATIONS • RECELL is contraindicated for the treatment of wounds clinically diagnosed as infected or with necrotic tissue present in the wound bed. • RECELL is contraindicated for the treatment of patients with a known hypersensitivity to trypsin or compound sodium lactate solution (Hartmann’s Solution). • The skin sample collection procedure specified for use of RECELL should not be used with patients having a known hypersensitivity to anesthetics, adrenaline/epinephrine, povidone‐iodine, or chlorhexidine solutions. AW‐IFU030‐7 5 WARNINGS • Autologous use only. • Wound beds treated with a cytotoxic agent (e.g., silver sulfadiazine) should be rinsed prior to application of the cell suspension. • RECELL is provided to the healthcare professional sterile and is intended for single use. • Do not reuse, freeze, or re‐sterilize device components. • Handle using aseptic technique. • Do not use RECELL or device components if packaging is damaged or there are signs of tampering. • Do not use RECELL or device components beyond the stated expiration date indicated on the adhesive Lot # and Expiration Date labels on the outer box packaging. • Choose a skin sample donor site that shows no evidence of surrounding cellulitis or infection. • For optimum cell viability, the skin sample should be processed immediately after harvesting. • If a skin sample is harvested and processed according to these instructions, it should require between 15 and 30 minutes of contact with the Enzyme. Contact in excess of 60 minutes is not recommended. • The Enzyme is derived from animal tissue and, although strict controls have been implemented in the manufacturing process to minimize the risk of pathogen contamination, a small risk of contamination exists and absolute freedom

  • Skin As a Mirror of Gastrointestinal Diseases
    Review article Skin as a mirror of gastrointestinal diseases Sunil Kumar Gupta1, Amanjot Kaur Arora1, Jasveen Kaur1, Veenu Gupta2, Deepinder Kaur2 Department of Dermatology, Venerology and Leprology1, Department of Microbiology2, Dayanand Medical College and Hospital, Ludhiana, Punjab, India ABSTRACT The closely related origins of the skin and the gastrointestinal system make for a fascinating grouping of diseases with concomitant involvement of these two important organ systems. The dermatologic manifestations may precede clinically evident gastrointestinal disease and help in early diagnosis, saving unnecessary wastage of time and resources. In this overview, we review the cutaneous manifestations of various hereditary, neoplastic and inflammatory gastrointestinal diseases including the various polyposis syndromes, hereditary colorectal cancers, inflammatory bowel diseases, etc. Dermatologic manifestations of acute and chronic hepatic and pancreatic diseases have also been discussed. This review underscores the importance of collaboration between dermatologists and gastroenterologists for better and efficient management of the affected patients.

    Wound Classification Presented by Dr. Karen Zulkowski, D.N.S., RN Montana State University Welcome! Thank you for joining this webinar about how to assess and measure a wound. 2 A Little About Myself… • Associate professor at Montana State University • Executive editor of the Journal of the World Council of Enterstomal Therapists (JWCET) and WCET International Ostomy Guidelines (2014) • Editorial board member of Ostomy Wound Management and Advances in Skin and Wound Care • Legal consultant • Former NPUAP board member 3 Today We Will Talk About • How to assess a wound • How to measure a wound Please make a note of your questions. Your Quality Improvement (QI) Specialists will follow up with you after this webinar to address them. 4 Assessing and Measuring Wounds • You completed a skin assessment and found a wound. • Now you need to determine what type of wound you found. • If it is a pressure ulcer, you need to determine the stage. 5 Assessing and Measuring Wounds This is important because— • Each type of wound has a different etiology. • Treatment may be very different. However— • Not all wounds are clear cut. • The cause may be multifactoral. 6 Types of Wounds • Vascular (arterial, venous, and mixed) • Neuropathic (diabetic) • Moisture-associated dermatitis • Skin tear • Pressure ulcer 7 Mixed Etiologies Many wounds have mixed etiologies. • There may be both venous and arterial insufficiency. • There may be diabetes and pressure characteristics. 8 Moisture-Associated Skin Damage • Also called perineal dermatitis, diaper rash, incontinence-associated dermatitis (often confused with pressure ulcers) • An inflammation of the skin in the perineal area, on and between the buttocks, into the skin folds, and down the inner thighs • Scaling of the skin with papule and vesicle formation: – These may open, with “weeping” of the skin, which exacerbates skin damage.

  • Angina Bullosa Haemorrhagica (Oral Blood Blister) (PDF)
    Patient Information Maxillo-facial Angina Bullosa Haemorrhagica (Oral Blood Blister) What is Angina Bullosa Haemorrhagica? Angina Bullosa Hemorrhagica (ABH) is a condition where an often painful, but benign blood-filled blister suddenly develops in the mouth. The blisters are generally not due to a blood clotting disorder or any other medical disorder. It is a fairly common, sudden onset and benign blood blistering oral (mouth) disorder. It mainly affects people over 45 years and both males and females are equally affected. Usually there is no family history of the condition. It may be associated with Type 2 Diabetes, a family history of diabetes or Hyperglycaemia. What are the signs and symptoms of ABH? The first indication is a stinging pain or burning sensation just before the appearance of a blood blister The blisters last only a few minutes and then spontaneously rupture (burst), leaving a shallow ulcer that heals without scarring, discomfort or pain They can reach an average size of one to three centimetres in diameter The Soft Palate (back of the mouth) is the most affected site If they occur on the palate and are relatively big, they may need to be de-roofed (cut and drained) to ease the sensation of choking Patient Information Occasionally blisters can occur in the buccal mucosa (cheek) and tongue Approximately one third of the patients have blood blisters in more than one location. What are the causes of ABH? More than 50% of cases are related to minor trauma caused by: hot foods, restorative dentistry (fillings, crowns etc) or Periodontal Therapy (treatment of gum disease).

    ■ - A HANDBOOK OF CLINICAL SIGNS IN BLACK AND BROWN SKIN - MUKWENDE M, TAMONV P, TURNER M FIRST EDITION �---0 � � - ·� · St Georges University of London www.blackandbrownskin.co.uk INTRODUCTION There is more and more literature on the need for medical schools to address the equality and diversity agenda in order to ensure that future doctors can effectively treat the diverse population in the UK. The COVID-19 pandemic has highlighted how marginalised and particularly BME communities have poorer health outcomes. If medicine does not decolonize its curriculum and teach students to recognise signs and symptoms on darker skin tones there will be delays in diagnosis or misdiagnosis (Gishen & Lokugamage 2019). As well as offering images of conditions on black and brown skins frequently omitted in text books we have also looked at language and descriptors that often assume the patient is white. GMC- EQUALITY, DIVERSITY "The principles of equality, diversity and fair treatment are embedded in our core ethical standards and requirements that doctors must meet in medical education and training. Implementing this strategy is a contribution to improving standards of care for all patients by raising awareness of our expectations and making sure: · Doctors are equipped to treat the diversity of patients and services users in the UK population, irrespective of where they train · Doctors are able to use their diverse backgrounds and experiences to deliver innovative care that can respond to the diverse needs of their patients ...

  • Minor Burn Injuries
    Hand and Plastic surgery Injury clinic Minor Burn Injuries Information for patients Your burn has been assessed in the Emergency Department and you have been referred to the Hand and Plastic surgery Injury clinic (HAPI) for review in around two days. This leaflet should help you understand more about your burn injury and how to look after it, both before and after you come to your appointment. Dressing changes Your burn may have been covered with a dressing, which will need to be kept clean and dry. You will usually have a dressing change and review of your wound two times a week in the plastic dressing clinic, followed by a final assessment of the burn injury in the HAPI clinic around two weeks after your burn. If your burn heals quickly you may be discharged sooner. The dressing should be changed in the HAPI clinic if it accidentally becomes wet, begins to fall off or if fluid seeps through from your burn. If this happens, please contact the HAPI clinic for advice. You will need to wear the dressing until your wound has healed well enough for you to leave it uncovered. Your burn has been dressed with: ........................................................................................................................................................................................................ ........................................................................................................................................................................................................ .......................................................................................................................................................................................................
