RESUMEN
This case report details our experience using a two-stage Biodegradable Temporizing Matrix (NovoSorb® PolyNovo Ltd) and autograft for acute reconstruction of a complex perineal burn wound in an elderly comorbid patient. A 77-year-old man sustained 42% full-thickness burns extending circumferentially from bilateral thighs and buttocks, across the entire perineal and genital regions up to his mid-trunk, following self-immolation using an accelerant. Early total burn wound excision was carried out with acute application of Biodegradable Temporizing Matrix to all affected sites. Excellent integration and vascularization of Biodegradable Temporizing Matrix took place despite the challenge of intermittent fecal contamination affecting the perineal and buttock burn sites and matrix colonization with multidrug-resistant organisms. Delamination and serial split-thickness skin autografting were carried out 42 days after the first matrix application with complete and robust graft take. Perineal burns present a reconstructive challenge due to the proximity of specialized structures such as the genitalia, urethral, and anal orifices. Restoration of complex anatomy and function may be required after debridement with increased risks of infection, contracture formation, and mortality compared with burns affecting other anatomical sites. Two-stage Biodegradable Temporizing Matrix represents a reliable reconstruction option for complex extensive perineal wounds in frail elderly patients, despite an unfavorable local microbial environment.

BACKGROUND: NovoSorbâ Biodegradable Temporising Matrix (BTM) is a synthetic dermal template recently approved for treatment of full thickness defects of the skin. It requires a two-stage reconstruction where it is initially placed into a defect to generate a neodermis, which is later covered by a split skin graft. It has previously been described for the treatment of acute full thickness burn injury, necrotising fasciitis and free flap donor site reconstruction. METHODS: A consecutive case series review of patients treated with BTM at Middlemore Hospital was performed. Patient demographics, defect aetiology, indications for dermal matrix use, surgical details, and complications were recorded using information gathered from the medical records. RESULTS: This case series included 25 patients with a range of defects resulting from acute full thickness burn injury, burn scar revision, necrotising soft-tissue infection, tumour excision and traumatic loss. In these patients, 72% of wounds were identified as complex defects with exposed bone or tendon. Complications encountered included infection, non-adherence and incomplete vascularisation. CONCLUSION: BTM provided a good reconstructive option for a wide range of defects, many of which were not amenable to immediate skin grafting. Once vascularised and ready for the second stage, it developed a red-pink colour and demonstrated capillary refill. Similar to other dermal matrices, infection was a commonly encountered problem. However, BTM proved more tolerant to this and was able to be salvaged in most cases, allowing the second stage to proceed as normal.

AIM: To describe the characteristics, circumstances and consequences of dog bite injuries in children in order to inform the discourse concerning preventative approaches. METHOD: A retrospective review of children presenting to the emergency department (ED) of the Women's and Children's Hospital (WCH) in South Australia between the years 2009 and 2011 was performed. RESULTS: A total of 277 children presented to the WCH with dog bite injuries between 2009 and 2011. Of those, 141(51.0%) were referred for admission. Injury rates were highest in those aged 0-4, declining thereafter with age. In the 0-4 year age group, 89.5% of children presented after being bitten by a familiar dog with 92.5% occurring at home. The head/neck region constituted the most common location for injuries. We found that 67.5% of dog bite injuries were provoked and occurred between the child and a familiar dog (78.0%). Dogs from the bull terrier group (20.0%) and Jack Russell Terriers (11.0%) were the two most documented breeds. Almost half of the children presenting during the specified timeframe required at least one operation under a general anaesthetic. Two children were referred to a psychologist for management of post-traumatic stress. CONCLUSION: Dog bite injuries are common in children and often require admission for inpatient care. This presents as a significant public health burden. For this reason, prevention initiatives need to be implemented on an ongoing basis.

BACKGROUND: A peripheral intravenous device (PIVD) provides venous access for the administration of medications, blood products and fluids. They can be associated with a risk of infection and other complications, which have prompted the development of evidence-based guidelines for their use at the Royal Adelaide Hospital (RAH). A previous audit performed at the RAH found unsatisfactory compliance with these guidelines across a group of wards. The Burns Unit performed poorly compared with other wards, but the reasons for this were not explored. METHODS: A repeat audit was performed for all PIVDs in the Burns Unit over a 3-week period and compliance with the PIVD safety guidelines was assessed. Factors influencing compliance were investigated and the evidence behind the guidelines was reviewed. RESULTS: Overall compliance with the seven safety criteria was 71%. Poorest compliance was for documentation of insertion date, which has implications for scheduling PIVD replacement. CONCLUSION: The guidelines are largely evidence-based; however, not all of them are feasible for all patients within a hospital. The Burns Unit had an overall compliance rate of 71%. Auditing of individual wards is not effective in assessing those wards' compliance with the guidelines as many PIVDs are inserted in other locations in the hospital. For compliance to improve, other areas of the hospital where PIVDs are inserted need to be targeted.

BACKGROUND: Aplasia cutis congenita (ACC) is a rare condition commonly affecting the scalp in which there is a focal deficiency of cutaneous tissues of varying severity ranging from an absence of skin through to full thickness defects involving deeper elements such as bone and dura. Lesions of the scalp can be associated with complications including infection, hemorrhage, thrombosis, and seizures. Opinions in the current literature regarding management of this condition are varied with both conservative and surgical management advocated. Conservative treatment consists of regular wound dressings and systemic antibiotics, while surgical management commonly involves skin grafting and local flaps. METHODS: A retrospective case review was performed to audit the outcomes of patients with ACC of the scalp managed at the Women's and Children's Hospital (WCH) in Adelaide, Australia from 2002 to 2012. Cases were identified from admission coding diagnoses and data was retrieved from patient case notes. RESULTS: Seventeen cases of ACC were identified. The most common location involved was the scalp vertex. Thirteen patients were managed conservatively and 4 had primary surgical intervention. Of the cases that were managed with primary surgery, 2 had complications. None of the conservatively managed patients had complications in the acute setting. CONCLUSIONS: At the WCH, we advocate adopting a conservative approach to management of ACC of the scalp. Defects can be successfully managed with a combination of regular dressings and systemic antibiotics. Regular wound monitoring is essential to detect any complications early to instigate appropriate treatment and determine the need for emergency surgical management.

BACKGROUND: The co-existence of diabetes mellitus (DM) in patients with acute pancreatitis (AP) is linked to poor outcomes. Four large epidemiological studies have suggested an aetiological role for DM in AP. The exact nature of this role is poorly understood. OBJECTIVE: To analyse the available clinical and experimental literature to determine if DM may play a causative role in AP. METHODS: A systematic search of the scientific literature was carried out using EMBASE, PubMed/MEDLINE, and the Cochrane Central Register of Controlled Trials for the years 1965-2011 to obtain access to all publications, especially randomized controlled trials, systematic reviews, and meta-analyses exploring the mechanisms of pathogenesis of AP in patients with DM. RESULTS: No clinical studies could be identified directly providing pathogenetic mechanisms of DM in the causation of AP. The available data on DM and its associated metabolic changes and therapy indicate that hyperglycaemia coupled with the factors influencing insulin resistance (tumour necrosis-α, NFκB, amylin) cause an increase in reactive oxygen species generation in acinar cells. CONCLUSIONS: Complex pathogenetic connections exist between AP and factors involved in the development and therapy of DM. Insulin resistance and hyperglycaemia, hallmarks of DM, are important factors linked to the susceptibility of diabetics to AP. Given the high morbidity associated with an attack of AP in a diabetic patient, targeting these two aspects by therapy may help not only to reduce the risk of development of AP, but may also help reduce the severity of an established attack in a diabetic patient.

Vitamin D deficiency has been reported in pediatric burn patients; however, no formal studies have been conducted in adult burn populations. The available literature on vitamin D status in burn patients has been reviewed. A literature search was conducted using Medline™, the Cochrane central register of controlled trials, and EMBASE to identify any trials of vitamin D deficiency in burn patients. Six published studies regarding vitamin D status in burn patients were found; however, five of these were in pediatric populations and several did not assess vitamin D levels as a major endpoint. Vitamin D deficiency has been demonstrated to result in itching, muscle weakness, and neuropathy, all of which are common postburn sequelae. The major source of vitamin D is synthesis in the skin with a small amount being absorbed through dietary intake. Population groups are at higher risk of vitamin D deficiency if they have inadequate exposure to UV light or reduced biosynthetic capability due to skin damage. Burn patients fall into both risk groups and also suffer common complaints that overlap with those reported by patients with vitamin D deficiency. Further research in adult burn patients is needed to determine the prevalence of deficiency in this population and whether vitamin D deficiency might influence postburn injury symptoms reported by patients.

INTRODUCTION: Wheat bags are therapeutic devices that are heated in microwaves and commonly used to provide relief from muscle and joint pain. The Royal Adelaide Hospital Burns Unit has observed a number of patients with significant burn injuries resulting from their use. Despite their dangers, the products come with limited safety information. METHODS: Data were collected from the Burns Unit database for all patients admitted with burns due to hot wheat bags from 2004 to 2009. This was analyzed to determine the severity of the burn injury and identify any predisposing factors. An experimental study was performed to measure the temperature of wheat bags when heated to determine their potential for causing thermal injury. RESULTS: 11 patients were admitted with burns due to hot wheat bags. The median age was 52 years and the mean total body surface area was 1.1%. All burns were either deep dermal (45.5%) or full thickness (54.5%). Ten patients required operative management. Predisposing factors (eg, neuropathy) to thermal injury were identified in 7 patients. The experimental study showed that hot wheat bags reached temperatures of 57.3°C (135.1°F) when heated according to instructions, 63.3°C (145.9°F) in a 1000 W microwave and 69.6°C (157.3°F) on reheating. CONCLUSIONS: Hot wheat bags cause serious burn injury. When heated improperly, they can reach temperatures high enough to cause epidermal necrosis in a short period of time. Patients with impaired temperature sensation are particularly at risk. There should be greater public awareness of the dangers of wheat bag use and more specific safety warnings on the products.
RESUMEN
A retrospective audit of length of hospital inpatient stay of all patients admitted to the Royal Adelaide Hospital Burns Unit over a 5-year period was performed. Data gathered from the Burns Unit database and records allowed patient division into two comparison groups: those younger than 70 years and those aged 70 years or older. Further comparison based on discharge destination was made in the ≥70 years group. Outcomes included length of stay, burn size, and discharge destination. A total of 1641 patients were included. The median length of stay was 5.0 days for patients younger than 70 years and 10.0 days for those aged 70 years or older (P < .0001). The mean percentage of TBSA burned was similar. A greater proportion of those aged 70 years or older were discharged to supported care facilities, such as nursing homes, and a greater proportion needed assessment for placement (P < .001) when compared with those younger than 70 years. The median length of stay of those aged 70 years or older who did not need assessment for placement was 9.0 days compared with 38.0 days for those who needed assessment (P < .0001). Elderly patients have, generally, nearly twice the length of stay of younger patients; when further subdivided according to discharge destination, the effect of placement delay (a social issue) becomes apparent and disturbing. This has significant implications, given the limited capacity and high cost of burn unit admission. A geriatrician will be appointed to the Burn Service over the next 12 months to assess whether earlier geriatric assessment can decrease the length of inpatient admission by facilitating a more efficient placement process.

AIMS: To facilitate the use of Biobrane for those burn care practitioners not familiar with this material. METHODS: Two techniques have been developed through extensive use of Biobrane over many years, in both sheet and glove form. These techniques have been described and illustrated with photographs. RESULTS: The use of these techniques has allowed the corresponding author to markedly reduce operating time and to easily apply the material single-handedly. CONCLUSION: Biobrane is a biosynthetic skin substitute primarily designed for the definitive treatment of superficial partial-thickness to mid-dermal burn injury. Once experienced with its use, the material is quite ubiquitous. The described techniques will facilitate the use of Biobrane for those not familiar with it.
