Cold Burn Injuries in the UK Nizamoglu et al. Burns & Trauma (2016) 4:36 DOI 10.1186/s41038-016-0060-x RESEARCH ARTICLE Open Access Cold burn injuries in the UK: the 11-year experience of a tertiary burns centre Metin Nizamoglu1*, Alethea Tan1, Tobias Vickers2, Nicholas Segaren1, David Barnes1 and Peter Dziewulski1 Abstract Background: Guidance for the management of thermal injuries has evolved with improved understanding of burn pathophysiology. Guidance for the management of cold burn injuries is not widely available. The management of these burns differs from the standard management of thermal injuries. This study aimed to review the etiology and management of all cold burns presenting to a large regional burn centre in the UK and to provide a simplified management pathway for cold burns. Methods: An 11-year retrospective analysis (1 January 2003–31 December 2014) of all cold injuries presenting to a regional burns centre in the UK was conducted. Patient case notes were reviewed for injury mechanism, first aid administered, treatment outcomes and time to healing. An anonymized nationwide survey on aspects of management of cold burns was disseminated between 13 July 2015–5 October 2015 to British Association of Plastic Reconstructive and Aesthetic Surgeons (BAPRAS) and Plastic Surgery Trainees Association (PLASTA) members in the UK. Electronic searches of MEDLINE, EMBASE and the Cochrane Library were performed to identify relevant literature to provide evidence for a management pathway for cold burn injuries. Results: Twenty-three patients were identified. Age range was 8 months–69 years. Total body surface area (TBSA) burn ranged from 0.25 to 5 %. Twenty cases involved peripheral limbs. Seventeen (73.9 %)cases were accidental, with the remaining six (26.1 %) cases being deliberate self-inflicted injuries. Only eight patients received first aid. All except one patient were managed conservatively. One case required skin graft application due to delayed healing. We received 52 responses from a total of 200 questionaires. Ninety percent of responders think clearer guidelines should exist. We present a simplified management pathway based on evidence identified in our literature search. Conclusions: Cold burns are uncommon in comparison to other types of burn injuries. In the UK, a disproportionate number of cold burn injuries are deliberately self-inflicted, especially in the younger patient population. Our findings reflect a gap in clinical knowledge and experience. We proposed a simplified management pathway for managing cold burn injuries, consisting of adequate first aid using warm water, oral prostaglandin inhibitors, deroofing of blisters and topical antithromboxane therapy.

  • Protecting Workers from Cold Stress
    QUICK CARDTM Protecting Workers from Cold Stress Cold temperatures and increased wind speed (wind chill) cause heat to leave the body more quickly, putting workers at risk of cold stress. Anyone working in the cold may be at risk, e.g., workers in freezers, outdoor agriculture and construction. Common Types of Cold Stress Hypothermia • Normal body temperature (98.6°F) drops to 95°F or less. • Mild Symptoms: alert but shivering. • Moderate to Severe Symptoms: shivering stops; confusion; slurred speech; heart rate/breathing slow; loss of consciousness; death. Frostbite • Body tissues freeze, e.g., hands and feet. Can occur at temperatures above freezing, due to wind chill. May result in amputation. • Symptoms: numbness, reddened skin develops gray/ white patches, feels firm/hard, and may blister. Trench Foot (also known as Immersion Foot) • Non-freezing injury to the foot, caused by lengthy exposure to wet and cold environment. Can occur at air temperature as high as 60°F, if feet are constantly wet. • Symptoms: redness, swelling, numbness, and blisters. Risk Factors • Dressing improperly, wet clothing/skin, and exhaustion. For Prevention, Your Employer Should: • Train you on cold stress hazards and prevention. • Provide engineering controls, e.g., radiant heaters. • Gradually introduce workers to the cold; monitor workers; schedule breaks in warm areas. For more information: U.S. Department of Labor www.osha.gov (800) 321-OSHA (6742) 2014 OSHA 3156-02R QUICK CARDTM How to Protect Yourself and Others • Know the symptoms; monitor yourself and co-workers. • Drink warm, sweetened fluids (no alcohol). • Dress properly: – Layers of loose-fitting, insulating clothes – Insulated jacket, gloves, and a hat (waterproof, if necessary) – Insulated and waterproof boots What to Do When a Worker Suffers from Cold Stress For Hypothermia: • Call 911 immediately in an emergency.

  • 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.

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).

  • Child Abuse: Skin Markers and Differential Diagnosis
    527 527 REVISÃO L Violência contra a criança: indicadores dermatológicos e diagnósticos diferenciais* Child abuse: skin markers and differential diagnosis Roberta Marinho Falcão Gondim 1 Daniel Romero Muñoz 2 Valeria Petri 3 Resumo: As denúncias de abuso contra a criança têm sido frequentes e configuram grave problema de saúde pública. O tema é desconfortável para muitos médicos, seja pelo treinamento insuficiente, seja pelo desconhecimento das dimensões do problema. Uma das formas mais comuns de violência contra a criança é o abuso físico. Como órgão mais exposto e extenso, a pele é o alvo mais sujeito aos maus- tratos. Equimoses e queimaduras são os sinais mais visíveis. Médicos (pediatras, clínicos-gerais e derma- tologistas) costumam ser os primeiros profissionais a observar e reconhecer sinais de lesões não aciden- tais ou intencionais. Os dermatologistas podem auxiliar na distinção entre lesões traumáticas inten- cionais, acidentais e doenças cutâneas que mimetizam maus-tratos. Palavras-chave: Contusões; Equimose; Queimaduras; Violência doméstica; Violência sexual Abstract: Reports of child abuse have increased significantly. The matter makes most physicians uncom- fortable for two reasons: a) Little guidance or no training in recognizing the problem; b - Not under- standing its true dimension. The most common form of child violence is physical abuse. The skin is the largest and frequently the most traumatized organ. Bruises and burns are the most visible signs.
