An eighteen-year review of intensive care requirements for paediatric burns in a regional burns service.

INTRODUCTION: Advances in burns management have reduced mortality. Consequently, efficient resource management plays an increasingly important role in improving paediatric burns care. This study aims to assess the support requirements and outcomes of paediatric burns patients admitted to a burns centre intensive care unit in comparison to established benchmarks in burns care. METHOD: A retrospective review of burns patients under the age of 16 years old, admitted to a regional burns service intensive care unit between March 1998 and March 2016 was conducted. RESULTS: Our analysis included 234 patients, with the percentage of TBSA affected by burn injury ranging from 1.5% to 95.0%. The median (IQR) %TBSA was 20.0% (11.0-30.0), and the observed mortality rate was 2.6% (6/234). The median (IQR) length of stay was 0.7 days/%TBSA burn (0.4-1.2), 17.9% (41/229) required circulatory support and 2.6% (6/234) required renal replacement. Mortality correlated with smoke inhalation injury (P < 0.001), %TBSA burn (P = 0.049) and complications (P = 0.004) including infections (P = 0.013). CONCLUSIONS: Among children with burn injuries who require intensive care, the presence of inhalational injury and the diagnosis of infection are positively correlated with mortality. Understanding the requirements for organ support can facilitate a more effective allocation of resources within a burns service.

A prospective study comparing the FLIR ONE with laser Doppler imaging in the assessment of burn depth by a tertiary burns unit in the United Kingdom.

INTRODUCTION: Laser Doppler imaging (LDI) is the 'gold standard' tool for the assessment of burn depth. However, it is costly. The FLIR ONE is a novel, mobile-attached, thermal imaging camera used to assess burn wound temperature. This study compares the FLIR ONE and LDI in assessing burn depth and predicting healing times. METHODS: Forty-five adult patients with burn wounds, presenting at 1-5 days, were imaged with the FLIR ONE and LDI. Infected, chemical and electrical burns were excluded. Healing potential was determined by comparing wound and normal skin temperature for the FLIR ONE and blood flow changes with the LDI. Healing potential was categorised into wounds healing in less than and over 21 days. Pearson's test was used to determine the correlation between changes in wound temperature and healing potential. RESULTS: Percent total body surface area (%TBSA) was in the range of 0.5-45. FLIR demonstrated a sensitivity of 66.67% and specificity of 76.67% in predicting healing within 21 days, while LDI demonstrated a sensitivity of 93.33% and specificity of 40%. The FLIR ONE showed a significant difference in the mean temperature changes between burns that healed in less than (0.1933 ± 0.3554) and over 21 days (-1 ± 0.4329) (P = 0.04904). Pearson's test showed a significant correlation between the difference in wound and normal skin temperature with healing times (P = 0.04517). CONCLUSION: The inexpensive FLIR ONE shows a significant correlation between changes in wound temperature and healing times. It is useful in predicting healing within 21 days. However, evaporative cooling at the wound surface can lead to overprediction of healing times and overtreatment. LAY SUMMARY: Background Laser Doppler imaging is currently the main tool for burn depth assessment. It works by analysing the blood flow in a burn wound. Based on these findings, it can predict the depth of the burn injury and predict if it will heal in less than or over 21 days. The main problem is that it is costly. The FLIR ONE is a novel, mobile-attached, thermal imaging camera. It can be used to assess burn depth by comparing the temperature of the burn wound to the surrounding normal skin. This information can then be used to predict healing times into less than and over 21 days. The issue being explored The usefulness of the FLIR ONE in assessing burn depth and predicting healing time when compared to the LDI. How was the work conducted? Forty-five adult patients who sustained a burn injury within the last five days were imaged with both the FLIR ONE and LDI. Those with infected, electrical or chemical burns were excluded. Healing potential was determined by comparing the temperature of the burn wound with normal skin for the FLIR ONE and by changes in wound blood flow with the LDI. Healing potential was categorised into wounds healing in less than and over 21 days. The correlation between the temperature changes of the burn wound and healing time was evaluated for the FLIR ONE. What we learned from the study This study was able to demonstrate that the FLIR ONE showed a significant correlation between the temperature difference between the burn wound and normal skin with healing times. When compared with the LDI, the FLIR ONE was useful in predicting if a burn wound will heal in less than 21 days. The FLIR ONE has advantages over the LDI, it is low cost, portable and produces instantaneous images. Ultimately, this developing technology may increase access to higher standard burn care in centres where LDI is not affordable.

Venous Congestion in Pedicled Frontal Branch Superficial Temporal Artery Flaps Reconstructions for Head and Neck Defects: A Review.

The superficial temporal artery (STA) flap is a versatile flap for head and neck defect reconstruction. It can be based on the frontal branch of the STA and an islanded 360-degree rotation arc for various defects on the scalp, cheek, and auricular region. It provides a nonmicrosurgical option for reconstructing such defects, which is itself relatively easy to perform. However, venous congestion is a problem than often can cause worry to the clinician and hence preclude its use. In this review, we revisit this flap in head and neck reconstruction, with case examples used for reconstruction of defects on the scalp, maxilla, lip, ear, and retroauricular area. The STA flap in our review can be used either as a fasciocutaneous flap or with its fascia alone. The main issue with the STA flap is that it is generally a high-inflow flap with variable outflow. Venous congestion is frequently encountered in our practice, and adequate management of the venous drainage in the postoperative period is crucial in ensuring its success as a versatile and viable option for head and neck reconstruction.

A challenging case of calcific myonecrosis of tibialis anterior and hallucis longus muscles with a chronic discharging wound.

The occurrence of calcific myonecrosis of the anterior compartment of the leg is rare. Common risk factors include a history of trauma, although little is known about the exact pathophysiology, latency period or triggering factors resulting in disease progression. Macroscopically, it begins with a single muscle being replaced by a fusiform calcified mass, which progresses peripherally. We present a rare case of a 7-year history of chronic discharging sinus overlying the site with protruding calcified muscle and discuss the senior author's wound management strategy and surgical considerations. The initial approach used dressing applications to reduce wound exudate while obtaining repeated imaging for disease progression comparison. Repeated CT scans showed significant disease progression from a single solitary amorphous soft tissue calcification to disseminated scattered calcified myonecrosis. In planning such surgeries, extensive debridement and temporary wound coverage is the first stage. Subsequent definitive coverage includes skin grafting of the remaining defect.

Relationship between multidisciplinary critical care and burn patients survival: A propensity-matched national cohort analysis.

OBJECTIVE: The aims of this study are: firstly, to investigate if admission to specialized burn critical care units leads to better clinical outcomes; secondly, to elucidate if the multidisciplinary critical care contributes to this superior outcome. METHODS: A multi-centre cohort analysis of a prospectively collected national database of 1759 adult burn patients admitted to 13 critical care units in England and Wales between 2005 and 2011. Units were contacted via telephone to establish frequency and constitution of daily ward rounds. Critical care units were categorized into 3 settings: specialized burns critical care units, generalized critical care units and 'visiting' critical care units. Multivariate logistic regression analysis and propensity dose-response analysis were used to calculate risk adjusted mortality. RESULTS: Multivariate logistic regression analysis shows that admission to a specialized burn critical care service is independently associated with significant survival benefit compared to generalized critical care unit (adjusted OR for in-hospital death 1.81, [95% CI, 1.24, 2.66]) and 'visiting' critical care services (adjusted OR for in-hospital death 2.24 [95% CI, 1.49, 3.38]). Further analysis using propensity dose-response analysis demonstrates that risk-adjusted in-hospital mortality rate decreased as the dose of multidisciplinary care increased, with an adjusted odds ratio of 1 (specialized burn critical care units), 1.81 (generalized critical care units) and 2.24 ('visiting' critical care units). CONCLUSIONS: Admission to a specialized burn critical care service is independently associated with significant survival benefit. This is, at least in part, due to care being provided by a fully integrated multidisciplinary team.

Cold burn injuries in the UK: the 11-year experience of a tertiary burns centre.

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.

The impact of major trauma network triage systems on patients with major burns.

INTRODUCTION: Trauma is a leading cause of death and disability worldwide. Patients presenting with severe trauma and burns benefit from specifically trained multidisciplinary teams. Regional trauma systems have shown improved outcomes for trauma patients. The aim of this study is to determine whether the development of major trauma systems have improved the management of patients with major burns. METHODS: A retrospective study was performed over a four-year period reviewing all major burns in adults and children received at a regional burns centre in the UK before and after the implementation of the regional trauma systems and major trauma centres (MTC). Comparisons were drawn between three areas: (1) Patients presenting before the introduction of MTC and after the introduction of MTC. (2) Patients referred from MTC and non-MTC within the region, following the introduction of MTC. (3) Patients referred using the urban trauma protocol and the rural trauma protocol. RESULTS: Following the introduction of regional trauma systems and major trauma centres (MTC), isolated burn patients seen at our regional burns centre did not show any significant improvement in transfer times, admission resuscitation parameters, organ dysfunction or survival when referred from a MTC compared to a non-MTC emergency department. There was also no significant difference in survival when comparing referrals from all hospitals pre and post establishment of the major trauma network. CONCLUSION: No significant outcome benefit was demonstrated for burns patients referred via MTCs compared to non-MTCs. We suggest further research is needed to ascertain whether burns patients benefit from prolonged transfer times to a MTC compared to those seen at their local hospitals prior to transfer to a regional burns unit for further specialist care.

Bubble bath burns: an unusual case.

We present an unusual case of flash burn injury in an adolescent following accidental combination of foaming bath bubbles and tea light candle flame. There has not been any reported similar case described before. This serves as a learning point for public prevention and clinicians managing burn injuries.

Using frozen section margin control technique to manage non-melanomatous skin lesions in high-risk sites.

BACKGROUND: In the UK, non-melanoma skin cancers (NMSCs) that are incompletely excised, recurrent or in sites high risk for incomplete excision are often offered Mohs micrographic surgery (MMS). Variations in waiting times and geographical access to MMS affect patient preference for other treatments. Our unit offers excision of such lesions under complete margin frozen section histological examination. METHODS: All NMSCs excised at our unit by complete margin frozen section histological analysis from 2010 to 2014 were retrospectively reviewed. The number of excisions required, complete excision rates and recurrences to date were analysed. RESULTS: Sixty-nine patients were treated using this technique with a total of 70 lesions excised. Approximately 71% of the excision margins were clear after primary excision, 27% at second excision and 1% at third excision. Patients had a mean follow-up of 12 months (range: 1-48) with no patients lost to follow-up and no recurrences reported to date. Ninety-eight percent of NMSC cases were completely excised and two cases were incompletely excised. CONCLUSION: We have found the rates of excision and recurrence of the high-risk NMSCs excised at our unit to be comparable to those reported with MMS. In addition, our data show that around 29% of patients would have had incomplete margins on primary resection, thus justifying the use of this technique in this group. We suggest that this technique is a safe and useful alternative to MMS in areas where waiting times or geographical patient preference may prohibit its use.

Pyoderma Gangrenosum Mimicking an Infected Wound following Dynamic Hip Screw Fixation.

Pyoderma gangrenosum (PG) is an inflammatory ulcerative neutrophilic dermatosis that can occur following skin trauma. The correct diagnosis is not often made immediately as the condition can mimic an infective appearance. This leads to delays in the appropriate management of high dose steroids. Although debridement can offer aid in resolving lesions, this is contraindicated in the acute phase as this can cause acceleration of the pathogenic process. Biopsy of the lesion does not offer a definitive diagnosis; therefore suspicion must be maintained as the diagnosis is ultimately a clinical one. Any postoperative pustular ulcerative lesion not improving despite antibiotic therapy that also yields negative bacteriological and fungal studies should lead to consideration of this diagnosis. We document the first case of PG developing following intertrochanteric femur fracture fixation using dynamic hip screw.

Assaults from corrosive substances and medico legal considerations in a large regional burn centre in the United Kingdom: calls for increased vigilance and enforced legislation.

Burn injuries from corrosive substances have been recognised as a common method of assault in low and middle income countries (LMICs) motivated by various factors. Such injuries often leave survivors with severely debilitating physical and psychological injuries and scars. The number of reported cases of acid assaults within the United Kingdom (UK) appears to be on the rise. As one of the largest regional burn centres in the UK, we have reviewed our experience of chemical burns from assault. This study aims to: (1) review the demographics, incidence and patient outcomes; (2) evaluate the long-term psychosocial support provided; and (3) review current criminal litigation proceedings and preventative legislations in the UK specific to assault by corrosive substances. A 15-year retrospective review of 21 burn injuries from assault with corrosive substances presenting to a regional burn unit was conducted. Victims were mostly young men; male perpetrators were more common. The most common motive cited was assault. The most common anatomical region affected was the face and neck. The number of victims who pursue litigation is disproportionately lower than the number of total cases at presentation. In an effort to better understand the legal considerations surrounding such assaults, we also collaborated with lawyers experienced in this particular field. We hope that our work will help educate healthcare professionals regarding the legal assistance and existing laws available to protect these patients.

Squamous cell carcinoma at an ileostomy site-Fifty-four years following colectomy for ulcerative colitis: A case report and literature review.

INTRODUCTION: Carcinoma arising at an ileostomy site is an extremely rare occurrence. The rate of malignancy arising at an ileostomy site is reported as being 2-4 of every 1000 cases. The development of squamous cell carcinoma at the mucocutaneous junction of an ileostomy is extremely rare. PRESENTATION OF CASE: We present a case of a 76-year-old male who developed squamous cell carcinoma at an ileostomy site fifty-four years after total colectomy as management for ulcerative colitis. DISCUSSION: Our literature review has identified only four similar cases previously published in English literature. All cases of squamous cell carcinoma developing in ileostomy have occurred after a minimum of twenty-six years following ileostomy. This suggests that the etiology may be due to chronic factors. CONCLUSION: Patients with chronic stomal inflammation, bleeding or persistent induration and/or mass formation should be followed up closely and investigated for recurrence or development of a new malignancy. There should be a low threshold to obtain an early definitive tissue diagnosis by taking biopsies to prevent local or systemic invasion.
