Atypical Wound • Wounds due to uncommon etiologies are called atypical wounds. • The most commonly encountered etiologies for an atypical wound include inflammatory causes, infections, vasculopathies, metabolic and genetic causes, malignancies and external causes. (Baranpski & Ayello, 2004)
Potential etiologies • Inflammatory causes • Vasculitis • Puoderma gangrenosum • Infections • Atypical mycobacteria • Deep fungal infections Araujo & Kirsner, 2004
Metabolic and genetic causes • Calciphylaxis • Sickle cell anemia • Malignancies • Squamous cell carcinoma • Basal cell carcinoma • Lymphoma • Kaposi’s sarcoma Araujo & Kirsner, 2004
Vasculopathies • Cryoglobulinemia • Cryofibrinogenaemia • External causes • Bites • Radiation Araujo & Kirsner, 2004
Scleroderma • A widespread connective tissue disease that involves changes in the skin, blood vessels, muscles, and internal organs.
Alternative Names • CREST syndrome • Progressive systemic sclerosis • Systemic sclerosis • Localized scleroderma
Affect 300,000 people in USA • Female : Male = 4:1 • Population • Infant elderly • Average age 22-55
Causes • Unknown • Not directly inherited • Over production of collagen in the skin and other organs • Risk factors • Occupational exposure to silica dust and polyvinyl chloride
Skin symptoms • Blueness or redness of fingers and toes in response to heat and cold • Ulcerations on fingertips or toes • Skin hardness / thickening • Skin is abnormally dark or light • Shiny hands and forearm • Small white lumps beneath the skin • Tight and mask-like facial skin • Hair loss
Other organs involvement • Bone, joint and muscle • Digestive system • Lung • Kidney • Gallbladder • Heart • Eye
Complications • Heart failure • Kidney failure • Malabsorption • Pulmonary fibrosis • Pulmonary hypertension
Medication • Decrease activity of immune system • Corticosteroids • Immunosuppressants (Methotrexate, Cytoxan) • Nonsteroidal anti-inflammatory drugs (NSAIDs) • Symptomatic control
Prognosis • In most patients, the disease slowly gets worse. • Death may occur from gastrointestinal, heart, kidney, or lung involvement. • Pulmonary sclerosis - most common cause of death.
Epidermolysis Bullosa (EB) • A rare inherited disease • The skin is very fragile and blisters formed in response to friction and to every day trauma • May also affect multiple systems of the body
Epidermolysis Bullosa • Epidermolysis simplex • Junctional epidermolysis bullosa • Dystrophic epidermolysis bullosa
Epidermolysis simplex • Largest group • Dominantly inherited disorder • One copy of the gene is faulty • Not life threatening • Blistering mainly limited to the hands, elbows, knees and feet • Reduce in severity as the child becomes older
Junctional epidermolysis bullosa • Recessively inherited disease • Both copies of the gene are faulty • The most serious type of EB, infants usually die during the first year of life • Generalized lesions • Affect mucous membrane
Dystrophic epidermolysis bullosa • Can be either dominant or recessive • Dominant – only mildly affected • Recessive – severely affected • Continuing blistering and ulceration of the skin follows everyday trauma
Lesions heal with scarring • result in strictures and contractures • limitation in mobility and eating • Predispose to skin cancer
Handling of the children • Small infants should never lift up under arms as painful blisters may result. • Older children should be encouraged to be independent in his / her early age so as to avoid trauma by others.
Aims of wound care • Encourage wound healing • Maintain daily activities • Social acceptability
Dressing choice • Wound contact layer dressing • eg. Mepitel, Urgotul • Non adherent dressing • eg. Melolin, Tricose, Mepliex • Alginate dressing
Clothing • Fine material clothing • Can be worn inside out to avoid rough seams • Remove internal labels • Padded footwear
Oral care • Affect mucous membrane • eg. oral blistering, bleeding, oral submucous fibrosis, oesophageal strictures • Dental decay • Due to fragility of oral mucosa • Fluoride supplement • Oral hygiene • ?? Tooth brushing • ?? Dentures
Nutrition • Dysphagia - gastrostomy feeding • Constipation – soluble fibre supplement
Mobility • Digital fusion • Results from repeated blistering and scarring • Plastic surgery • Splintage
Pyoderma Gangrenosum (PG) • An inflammatory process resulting in ulceration of unknown etiology. • It was an immune-mediated inflammatory condition characterized by ulcerative skin lesions. • Affect about 5 percent of people with ulcerative colitis Regueiro, et al, 2003 Papageprgiou, Mathew, Kaniorou-Larai, & Yiakoumetis, 2007
Systemic diseases associated with PG • Associated with other conditions in up to 75% of patients. • Inflammatory bowel disease • Arthritis • Hemotologic abnormalities • Lymphoma • Myeloma • Leukemia • Immunologic abnormalities • SLEAraujo & Kirsner, 2005
Appear as a blister, red bump, or pustule • Appear alone or in a group • Pustules progress rapidly and develop into the ulcer • Commonly found on the extremities • More frequently on the legs than on the arms Nkrumah, Addo, & Tachi, 2005 Papageprgiou, et al, 2007
Diagnosis • No single diagnostic test available for PG • It is a clinical diagnosis of exclusion • Based on excluding other causes and evaluating the patient for underlying systemic disease. Trent & Kirsner, 2001
Treatment • Treat underlying disease • Corticosteroid • Immunosuppressant • Cyclosporine • Systemic antibiotics • Anaesthetic
Wound management • Control pain • Necrotic tissue • surgical debridement is contraindicated as it may result in even worse ulceration • Avoidance of trauma at dressing removal • disturbance can generate an even greater inflammatory response and stimulate deterioration Araujo, & Kirsner, 2004
Negative pressure therapy • may be used to assist debridement when the disease is stable • Debridement and skin grafting • can be considered when condition is under controlled • surgery may reactive the disease Moffatt, Martin, Smithdale, 2007
