Burn Rehabilitation

Interventions for postburn pruritus

BACKGROUND

Postburn pruritus (itch) is a common and distressing symptom experienced on healing or healed burn or donor site wounds. Topical, systemic, and physical treatments are available to control postburn pruritus; however, it remains unclear how effective these are.

OBJECTIVES

To assess the effects of interventions for treating postburn pruritus in any care setting.

SEARCH METHODS

In September 2022, we searched the Cochrane Wounds Specialised Register, the Cochrane Central Register of Controlled Trials (CENTRAL), Ovid MEDLINE (including In-Process & Other Non-Indexed Citations), Ovid Embase, and EBSCO CINAHL Plus. We also searched clinical trials registries and scanned references of relevant publications to identify eligible trials. There were no restrictions with respect to language, publication date, or study setting.

SELECTION CRITERIA

Randomised controlled trials (RCTs) that enrolled people with postburn pruritus to compare an intervention for postburn pruritus with any other intervention, placebo or sham intervention, or no intervention.

DATA COLLECTION AND ANALYSIS

We used the standard methodological procedures expected by Cochrane. We used GRADE to assess the certainty of the evidence.

MAIN RESULTS

We included 25 RCTs assessing 21 interventions with 1166 randomised participants. These 21 interventions can be grouped into six categories: neuromodulatory agents (such as doxepin, gabapentin, pregabalin, ondansetron), topical therapies (such as CQ-01 hydrogel, silicone gel, enalapril ointment, Provase moisturiser, beeswax and herbal oil cream), physical modalities (such as massage therapy, therapeutic touch, extracorporeal shock wave therapy, enhanced education about silicone gel sheeting), laser scar revision (pulsed dye laser, pulsed high-intensity laser, fractional CO2 laser), electrical stimulation (transcutaneous electrical nerve stimulation, transcranial direct current stimulation), and other therapies (cetirizine/cimetidine combination, lemon balm tea). Most RCTs were conducted at academic hospitals and were at a high risk of performance, attrition, and detection bias. While 24 out of 25 included studies reported change in burn-related pruritus, secondary outcomes such as cost-effectiveness, pain, patient perception, wound healing, and participant health-related quality of life were not reported or were reported incompletely. Neuromodulatory agents versus antihistamines or placebo There is low-certainty evidence that doxepin cream may reduce burn-related pruritus compared with oral antihistamine (mean difference (MD) -2.60 on a 0 to 10 visual analogue scale (VAS), 95% confidence interval (CI) -3.79 to -1.42; 2 studies, 49 participants). A change of 2 points represents a minimal clinically important difference (MCID). Due to very low-certainty evidence, it is uncertain whether doxepin cream impacts the incidence of somnolence as an adverse event compared to oral antihistamine (risk ratio (RR) 0.64, 95% CI 0.32 to 1.25; 1 study, 24 participants). No data were reported on pain in the included study. There is low-certainty evidence that gabapentin may reduce burn-related pruritus compared with cetirizine (MD -2.40 VAS, 95% CI -4.14 to -0.66; 1 study, 40 participants). A change of 2 points represents a MCID. There is low-certainty evidence that gabapentin reduces the incidence of somnolence compared to cetirizine (RR 0.02, 95% CI 0.00 to 0.38; 1 study, 40 participants). No data were reported on pain in the included study. There is low-certainty evidence that pregabalin may result in a reduction in burn-related pruritus intensity compared with cetirizine with pheniramine maleate (MD -0.80 VAS, 95% CI -1.24 to -0.36; 1 study, 40 participants). A change of 2 points represents a MCID. There is low-certainty evidence that pregabalin reduces the incidence of somnolence compared to cetirizine (RR 0.04, 95% CI 0.00 to 0.69; 1 study, 40 participants). No data were reported on pain in the included study. There is moderate-certainty evidence that ondansetron probably results in a reduction in burn-related pruritus intensity compared with diphenhydramine (MD -0.76 on a 0 to 10 numeric analogue scale (NAS), 95% CI -1.50 to -0.02; 1 study, 38 participants). A change of 2 points represents a MCID. No data were reported on pain and adverse events in the included study. Topical therapies versus relevant comparators There is moderate-certainty evidence that enalapril ointment probably decreases mean burn-related pruritus compared with placebo control (MD -0.70 on a 0 to 4 scoring table for itching, 95% CI -1.04 to -0.36; 1 study, 60 participants). No data were reported on pain and adverse events in the included study. Physical modalities versus relevant comparators Compared with standard care, there is low-certainty evidence that massage may reduce burn-related pruritus (standardised mean difference (SMD) -0.86, 95% CI -1.45 to -0.27; 2 studies, 166 participants) and pain (SMD -1.32, 95% CI -1.66 to -0.98). These SMDs equate to a 4.60-point reduction in pruritus and a 3.74-point reduction in pain on a 10-point VAS. A change of 2 VAS points in itch represents a MCID. No data were reported on adverse events in the included studies. There is low-certainty evidence that extracorporeal shock wave therapy (ESWT) may reduce burn-related pruritus compared with sham stimulation (SMD -1.20, 95% CI -1.65 to -0.75; 2 studies, 91 participants). This equates to a 5.93-point reduction in pruritus on a 22-point 12-item Pruritus Severity Scale. There is low-certainty evidence that ESWT may reduce pain compared with sham stimulation (MD 2.96 on a 0 to 25 pressure pain threshold (PPT), 95% CI 1.76 to 4.16; 1 study, 45 participants). No data were reported on adverse events in the included studies. Laser scar revision versus untreated or placebo controls There is moderate-certainty evidence that pulsed high-intensity laser probably results in a reduction in burn-related pruritus intensity compared with placebo laser (MD -0.51 on a 0 to 1 Itch Severity Scale (ISS), 95% CI -0.64 to -0.38; 1 study, 49 participants). There is moderate-certainty evidence that pulsed high-intensity laser probably reduces pain compared with placebo laser (MD -3.23 VAS, 95% CI -5.41 to -1.05; 1 study, 49 participants). No data were reported on adverse events in the included studies.

AUTHORS' CONCLUSIONS

There is moderate to low-certainty evidence on the effects of 21 interventions. Most studies were small and at a high risk of bias related to blinding and incomplete outcome data. Where there is moderate-certainty evidence, practitioners should consider the applicability of the evidence for their patients.

Comparing novel virtual reality and nursing standard care on burn wound care pain in adolescents: A randomized controlled trial

PURPOSE

This study compared the effectiveness of age-appropriate, high technology, interactive virtual reality (VR) distraction with standard care (SC) provided by the nurse on adolescents' acute procedural pain intensity perception during burn wound care treatment in the ambulatory clinic setting.

DESIGN

This randomized controlled trial included 43 adolescents ages 10-21 from the ambulatory burn clinic of a large children's hospital.

METHODS

Blinded study participants were randomly assigned to either VR or SC (non-significantly different, current mean burn surface area, 1.3 and 1.7, respectively) during the first burn wound care procedure in the burn clinic. Blinded research staff collected pre-procedure data including Spielberger's State-Trait Anxiety Inventory and postprocedure wound care pain intensity using the Adolescent Pediatric Pain Tool. A total of 41 participants completed all study procedures.

RESULTS

No statistically significant difference in burn wound care procedural pain was noted between the VR and SC groups after adjusting for several factors. Pre-procedure state and trait anxiety correlated with reported pre-procedure pain. Wound care pain was found to be significantly associated with pre-wound care pain score, time from original burn to clinic burn care treatment, and length of wound care treatment. These factors accounted for approximately 45% of the variation in pain scores during wound care treatment.

PRACTICE IMPLICATIONS

VR distraction can be a useful pain management strategy but may not take the place of the unique nurse-patient relationship that occurs during clinical encounters. Tailoring pain management during burn wound care requires consideration of anxiety, time from the burn injury to the wound care procedure, length of time of the wound care procedure, and pretreatment pain level. Knowing patients' needs, desires, and temperaments along with the specifics about the healthcare procedures are critical to formulating individualized care plans that may or may not include VR. Newer technology, such as easier-to-use, less expensive VR, may assist with translation into practice making its clinical use more routine.

Burn Injury Complications Impacting Rehabilitation

Successful post-burn rehabilitation requires an understanding of a wide range of complications to maximize functional recovery. This article reviews a range of potential challenges including burn scar contracture, amputation, peripheral nerve injury, heterotopic ossification, dysphagia, altered skin physiology, pain, and pruritis. The overall focus is to serve as a guide for post-injury therapy and rehabilitation spanning the phases of care and considering evidence-based approaches, prevention, and treatment with an ultimate goal of aiding in the functional recovery and long-term quality of life for burn survivors.

Serial Casting as an Effective Method for Burn Scar Contracture Rehabilitation: A Case Series

Guidelines and protocols for orthoses in burn scar contracture rehabilitation are limited. The current study aims to determine the optimal frequency of casting, potentially facilitating the development of a serial casting protocol. Previous literature supporting casting has low generalizability due to methodology limitations. Seven patients with burn scar contracted joints, who did not respond to traditional therapy, were recruited in this study. Patients were serially casted once, three times, or five times a week. Joint range of motion was maximized with stretching and exercise techniques before every new cast application. Across all patients, active range of motion increased from 65.8 ± 27.8° to 108.1 ± 23.3° with casting; or from 57.8 ± 16.2% to 96.7 ± 2.9% of normal. Similarly, scars improved from 9.5 ± 1.5 to 4.9 ± 1.4 on the Modified Vancouver Scar Scale score. This therapeutic effect was achieved within an average of 8.5 ± 3.7 d and 4.0 ± 2.2 new cast applications. Given the study findings, the procedures outlined could be used to develop a standardized serial casting protocol for burn scar contracture rehabilitation.

Reshaping the Endogenous Electric Field to Boost Wound Repair via Electrogenerative Dressing

The endogenous electric field (EF) generated by transepithelial potential difference plays a decisive role in wound reepithelialization. For patients with large or chronic wounds, negative-pressure wound therapy (NPWT) is the most effective clinical method in inflammation control by continuously removing the necrotic tissues or infected substances, thus creating a proproliferative microenvironment beneficial for wound reepithelialization. However, continuous negative-pressure drainage causes electrolyte loss and weakens the endogenous EF, which in turn hinders wound reepithelialization. Here, an electrogenerative dressing (EGD) is developed by integrating triboelectric nanogenerators with NPWT. By converting the negative-pressure-induced mechanical deformation into electricity, EGD produces a stable and high-safety EF that can trigger a robust epithelial electrotactic response and drive the macrophages toward a reparative M2 phenotype in vitro. Translational medicine studies confirm that EGD completely reshapes the wound EF weakened by NPWT, and promotes wound closure by facilitating an earlier transition of inflammation/proliferation and guiding epithelial migration and proliferation to accelerate reepithelialization. Long-term EGD therapy remarkably advances tissue remodeling with mature epithelium, orderly extracellular matrix, and less scar formation. Compared with the golden standard of NPWT, EGD orchestrates all the essential wound stages in a noninvasive manner, presenting an excellent prospect in clinical wound therapy.

Profile of pediatric out-patients managed by physiotherapists at Federal Medical Center, Abeokuta: a retrospective review

Background

Pediatric physiotherapists help children to achieve their optimal physical development. The present study was aimed to evaluate the out-patient pediatric conditions managed by physiotherapists in Federal Medical Centre, Abeokuta, Nigeria (FMCA).

Methods

The present study included all children attended to at Pediatric Unit (outpatient) of FMCA in the period between the beginnings of May 20121 to the end of May 2022. The clinic runs every Tuesdays and Thursdays. All children below and equals to 15 years of age were included. Complete clinical, socio-demographic characteristics of patients and parents were manually scrapped from the electronic medical records (EMR) of the hospital. Descriptive statistics was used to present the results.

Results

During this period a total of 160 patients presented with different disorders were seen. There were 100 males (62.5%) and 60 females (37.5%). Cerebral palsy which can be classified as a neurological disorder was the most common condition managed (63.7%). Obstetric brachial palsy injury (OBPI), injection palsy, post-immobilization stiffness, congenital talipes equinivarus, and among others were managed during this period. Cerebral palsy was common among males, obstetric brachial palsy injury, and injection palsy. Cerebral palsy patients had late presentation for physiotherapy (1–5 years). Only 2 patients out of 11 with OBPI came for early physiotherapy. There is higher risk for cerebral palsy and OBPI among primiparous mothers.

Conclusions

It was concluded that neurological disorders are the most common pediatric cases managed by physiotherapists in Federal Medical Centre, Abeokuta, with cerebral palsy having higher prevalence.

Objective Burn Scar Assessment in Clinical Practice Using the Cutometer©: Introduction and Validation of a Standardized Measurement Protocol

An objective burn scar assessment is essential to informed therapeutic decision-making and to monitor scar development over time. However, widely employed scar rating scales show poor inter-rater reliability. For this study we developed a standardized measurement protocol for the Cutometer© applicable for objective burn scar assessment in everyday clinical practice. We developed a measurement protocol for the Cutometer© MPA 580 including a scar site relocation technique based on anatomical landmarks. The protocol emerged through several steps: Identifying key factors for valid and reliable measurements, preliminary testing, specification of technical details, refining the protocol and final testing. Consecutively, the protocol was validated for inter-rater reliability by assessing 34 burn scars in 17 patients by four clinicians and computing an Intra-class Correlation Coefficient (ICC). Parameter R0, representing scar pliability, was identified as the best suited output parameter yielding excellent inter-rater reliability for average measures (ICC 0.92 [95% CI 0.86; 0.96]) and acceptable reliability for single measures (ICC: 0.74 [0.61; 0.84]). The pressure applied on the measuring probe was identified as an influential confounding factor for reliable measurements. Rater gender did not influence reliability of measurements. The introduced standardized measurement protocol for the Cutometer© MPA 580 enables an objective and reliable burn scar assessment for clinical as well as research purposes.

An Algorithm for Reconstruction of Electrical Injuries of the Scalp

BACKGROUND

Electrical injuries of the scalp are a frequent occurrence in developing countries. Burns can be contact or conductive and result in extensive tissue damage. The authors present their experience with treatment of scalp and calvarial electrical injuries and propose a management algorithm.

METHODS

This was a retrospective cohort study comprising all patients with electrical injuries of the scalp treated at the authors' center between January of 2010 and December of 2016. Noncontrast computed tomography scans were obtained to assess viability of the calvarium in patients who presented more than 2 weeks after injury. Single-stage débridement and reconstruction were performed. All nonviable soft tissue and bone was removed. Soft-tissue reconstruction was performed with skin grafts, local scalp flaps, pedicled trapezius flaps, and free flaps (anterolateral thigh, latissimus dorsi, and scapular). Cranioplasty was performed in a delayed manner with autologous bone grafts.

RESULTS

Over a 7-year period, a total of 52 patients underwent scalp reconstruction for high-voltage (44 patients) and low-voltage (eight patients) electrical injury. All patients underwent successful soft-tissue reconstruction. Osteomyelitis with draining sinuses developed in three patients; these patients underwent flap re-elevation and bone débridement, which resulted in a healed wound and stable reconstruction. Cranioplasty was performed with split calvarial grafts in two patients and split rib grafts in four patients. One patient underwent scalp tissue expansion for hair restoration.

CONCLUSION

The authors propose an algorithm for reconstruction of electrical injuries of the scalp. Thorough débridement of the calvarium is the most important determinant of a successful outcome.

Outcomes following burn injury in intensive care patients with major psychiatric disorders

AIMS

Patients with psychiatric comorbidity have been shown to experience high rates of burn injury. Burn epidemiology, etiology, and outcomes have been sparsely documented for patients with major psychiatric disorders. The aim of this study was to analyze the epidemiologic characteristics and outcomes in intensive care burn patients with pre-existing and acute major psychiatric disorders .

METHODS

A retrospective study was performed including intensive care burn patients admitted between March 2007 and December 2020. Demographic, clinical and epidemiological data were collected and analyzed. Major psychiatric co-morbidities were collected according to ICD-9 and ICD-10 classifications. Patients were stratified according to F-diagnoses.

RESULTS

A total of 1325 patients were included. 16.6 % of all patients had one or more major psychiatric disorders- 9.3 % with anxiety, dissociative, stress-related, somatoform and other nonpsychotic mental disorders, 9.2 % with mood (affective) disorders, 3.5 % with schizophrenia and other non-mood psychotic disorders, and 1.8 % with disorders of adult personality and behavior. Patients with major psychiatric disorders presented with significantly higher burn severity, reflected by higher abbreviated burn severity index (ABSI) scores (5.9 vs. 5.3, p < 0.001) and larger total body surface area (TBSA) affected (15.9 vs. 12.5 %, p = 0.002). Burned TBSA ≥ 30 and inhalation injuries were observed more frequently in patients with MDP, however without statistical significance. They also experienced prolonged hospital length-of-stay (LOS) (25.5 vs. 16.3 days, p < 0.001), prolonged intensive care unit LOS (14.8 vs. 7.7 days, p < 0.001), underwent surgical interventions (3.5 vs. 2.3, p < 0.001) and mechanical ventilation more frequently (34.1 % vs. 16.5 %, p = 0.43) and had significantly longer ventilation durations (73.5 vs. 31.2 h, p = 0.002). Mortality rates were lower compared to patients without major psychiatric disorders (5.9 vs. 8.1, p < 0.001).

CONCLUSIONS

The prevalence of major psychiatric disorders in burn patients is considerably high. Patients with psychiatric comorbidities were found to have greater burn severity, prolonged total hospital and ICU LOS, underwent surgical interventions and mechanical ventilation more frequently and had prolonged ventilation duration. Our results highlight the importance of identifying burn patients with major psychiatric disorders who may necessitate additional resources and require extensive inpatient psychiatric care and counseling.

Rehabilitation interventions after hand burn injury in adults: A systematic review

The aim of this review was to summarise the current evidence regarding the effectiveness of rehabilitation interventions in improving hand function, range of motion (ROM), hand strength, scar outcome, return to work, level of impairment/disability, level of burn knowledge and decreasing edema following hand burns in adult burn survivors. This review provides evidence-based support for the use of rehabilitation interventions for burn rehabilitation professionals. The following data sources were searched: MEDLINE, EMBASE and CINAHL from their inception up to February 2021, reference lists from all the included full-text articles were screened for additional relevant publications and monthly Google Scholar searches until December 23rd 2021 to make sure all new pertinent published articles after February 2021 would be included. Thirty-five studies were included in this review including 14 RCTs. Most of the included studies were Level 4 (46%; 16/35) and Level 2 (40%; 14/35) evidence. Only four studies were classified as Level 3 (14%; 5/35) evidence and none were considered Level 1. Most studies received a score of 5-9 (54%; 19/35) (Moderate quality). Fourteen studies received a score of ≥ 10 (40%; 14/35) (High quality) and only 2 studies received a score of< 5 (6%; 2/35) (Low quality). Articles were categorized according to the primary outcome targeted by the intervention. Clinical recommendations on higher-level evidence interventions are presented. This review supports the clinical practice of the following interventions: 1) The use of adhesive compression wraps for patients who have increased edema to increase hand function and ROM; 2) The use of compression (adhesive compressive wrap, compression bandage or intermittent compression pump) to decrease hand edema following burn injury; 3) Participating in general rehabilitation to increase hand function and patient perceived level of disability; 4) The use of an orthosis to increase ROM and a dynamic MCP orthosis to increase hand function; 5) If available, incorporate the use of VR based rehabilitation to increase hand function and hand strength; 6) The use of paraffin to increase hand PROM; 7) The use of gels to reduce hand scar thickness; 8) The use of an education component in rehabilitation to increase the level of burn knowledge. The limitations of this study are also discussed. Further research with robust methodology is needed to investigate the potential benefits of treatment interventions included in this review.

Evaluation of Kinesiophobia in Survivors of Major Burn Injury

Kinesiophobia, the fear of movement and re-injury, has not been described in burn injury survivors. Physical activity is a key component of burn rehabilitation programs. Yet, not all burn survivors exercise at the recommended level. This is an exploratory study examining the association of the demographics and injury characteristics of burn survivors with a fear of movement. The subjective fear of movement was measured using the Tampa Scale for Kinesiophobia (TSK). The TSK score was compared between several demographics and injury characteristics by performing the independent sample t-test. Sixty-six percent of subjects in our study (n=35), reported high levels of kinesiophobia (score 37 or above). The mean scores of the TSK were greater in males (40.7), non-White (43.0), Hispanic/Latino (41.1), age greater than 50 years (42.3), and total body surface area (TBSA) burn of >15% compared to females (36.9), White (38.5), non-Hispanic/Latino (39.3), age 50 years or less (38.1), and TBSA 15% or less (39.4) respectively. However, with the exception of time post injury, none of the mean differences were statistically significant. Subjects who had sustained a burn injury more than 12 months ago showed higher levels of kinesiophobia than the subjects who were injured within 12 months with a mean difference of 7.35 (p=.01). Thus, this study highlights the importance of (i) continued, long-term follow up for burn survivors, and (ii) appropriate educational and treatment interventions to address any underlying existing, new, or emerging medical issues that may contribute to the fear or avoidance of movement.

The degree of joint range of motion limitations after burn injuries during recovery

INTRODUCTION

The aim of this study was to determine the degree of ROM limitations of extremities, joints and planes of motion after burns and its prevalence over time.

METHOD

The database of a longitudinal multicenter cohort study in the Netherlands (2011-2012) was used. From patients with acute burns involving the neck, shoulder, elbow, wrist, hip, knee and ankle joints that had surgery, ROM of 17 planes of motion was assessed by goniometry at 3, 6 weeks, 3-6-9 and 12 months after burns and at discharge.

RESULTS

At 12 months after injury, 12 out of 17 planes of motion demonstrated persistent joint limitations. The five unlimited planes of motion were all of the lower extremity. The most severely limited joints at 12 months were the neck, ankle, wrist and shoulder. The lower extremity was more severely limited in the early phase of recovery whereas at 12 months the upper extremity was more severely limited.

CONCLUSION

The degree of ROM limitations and prevalence varied over time between extremities, joints and planes of motion. This study showed which joints and planes of motion should be watched specifically concerning the development of scar contracture.

The relation between satisfaction with appearance and race and ethnicity: A National Institute on Disability, Independent Living, and Rehabilitation Research burn model system study

Research supports that people of color in the U.S. have poorer outcomes after burn injury compared to White individuals. The current study sought to explore burn health disparities by testing the relationship between racial and ethnic minority status, a proxy for systemic discrimination due to race and ethnicity, with two key constructs linked to functional outcomes, satisfaction with appearance and social community integration. Participants included 1318 burn survivors from the Burn Model System National Database (mean age = 40.2, SD = 12.7). Participants completed measures of satisfaction with appearance and social community integration at baseline, 6-, 12-, and 24-months after burn injury. Linear regressions revealed that racial and ethnic minority status significantly related to lower satisfaction with appearance and social community integration compared to White individuals at all time points. In addition, satisfaction with appearance continued to significantly relate to greater social community integration even while accounting for race and ethnicity, age, sex, burn size, and physical disability at 6-, 12-, and 24-month time points. Overall, the study supports that racial and ethnic minority burn survivors report greater dissatisfaction with their appearance and lower social community reintegration after burn injury.

The Affordable Care Act and its Effects on Trauma Care Access, Short- and Long-term Outcomes and Financial Impact: A Review Article

Objective

The purpose of this study is to evaluate the current evidence regarding the impact of the ACA on trauma outcomes and the financial impact on trauma patients and trauma systems.

Background

Traumatic injuries are the leading cause of death and disability between the ages of 1 to 47 years. Uninsured status has been associated with worse outcomes and higher financial strain. The Affordable Care Act (ACA) was signed into law with the aim of increasing health insurance coverage. Despite improvements in insured status, it is unclear how the ACA has affected trauma.

Methods

We conducted a literature search using PubMed and Google Scholar for peer-reviewed studies investigating the impact of the ACA on trauma published between January 2017 and April 2021.

Results

Our search identified 20 studies that evaluated the impact of ACA implementation on trauma. The evidence suggests ACA implementation has been associated with increased postacute care access but not significant changes in trauma mortality. ACA implementation has been associated with a decreased likelihood of catastrophic health expenditures for trauma patients. ACA was also associated with an increase in overall reimbursement and amount billed for trauma visits, but a decrease in Medicaid reimbursement.

Conclusions

Some improvements on the financial impact of ACA implementation on trauma patients and trauma systems have been shown, but studies are limited by methods of calculating costs and by inconsistent pre-/post-ACA timeframes. Further studies on cost-effectiveness and cost-benefit analysis will need to be conducted to definitively determine the impact of ACA on trauma.

Adolescents with and without head and neck burns: comparison of long-term outcomes in the burn model system national database

INTRODUCTION

Facial burns account for persistent differences in psychosocial functioning in adult burn survivors. Although adolescent burn survivors experience myriad chronic sequelae, little is known about the effect of facial injuries. This study examines differences in long-term outcomes with and without head and neck involvement.

METHODS

Data collected for 392 burn survivors between 14-17.9 years of age from the Burn Model System National Database (2006-2015) were analyzed. Comparisons were made between two groups based on presence of a head and neck burn (H&N) using the following patient reported outcome measures: Satisfaction with Appearance Scale, Satisfaction with Life Scale, Community Integration Questionnaire, and Short Form-12 Health Survey at 6, 12, and 24 months after injury. Regression analyses were used to assess association between outcome measures and H&N group at 12-months.

RESULTS

The H&N group had more extensive burns, had longer hospital stays, were more likely to be burned by fire/flame and were more likely to be Hispanic compared to the non-H&N group. Regression analysis found that H&N burn status was associated with worse SWAP scores. No significant associations were found between H&N burn status and other outcome measures.

CONCLUSIONS

Adolescents with H&N burn status showed significantly worse satisfaction with appearance at 12-months after injury. Future research should examine interventions to help improve body image and coping for adolescent burn survivors with head and neck burns.

5 -Year Retrospective Analysis of a Vented Mobility Algorithm in the Burn ICU

Early mobilization with mechanically ventilated patients has received significant attention within recent literature, however limited research has focused specifically on the burn population. The purpose of this single center, retrospective analysis was to review the use of a burn critical care mobility algorithm, to determine safety and feasibility of a burn vented mobility program, share limitations preventing mobility progression at our facility, and discuss unique challenges to vented mobility with intubated burn patients. A retrospective review was completed for all intubated burn center admissions between January 2015 to December 2019. Burn Therapy notes were then reviewed for data collection, during the intubation period, using stages of the mobility algorithm. In 5 years following initial implementation, the vented mobility algorithm was utilized on 127 patients with an average total body surface area of 22.8%. No adverse events occurred. Stage 1 (Range of motion) was completed with 100% of patients (n=127). Chair mode of bed, stage 2a, was utilized in 39.4%(n=50) of patients, while 15.8% (n=20) of patients were dependently transferred to the cardiac chair in stage 2b. Stage 3 (sitting on the edge-of-bed) was completed with 25% (n=32) of patients, with 11% (n=14) progressing to stage 5 (standing), and 3.9% (n=5) actively transferring to a chair. In 5 years, only 4.7% (n=6) reached stage 6 (ambulation). The most common treatment limitations were medical complications (33%) and line placement (21%). Early mobilization during mechanical ventilation is safe and feasible within the burn population, despite challenges including airway stability, sedation, and line limitations.

Validation of PROMIS-29 domain scores among adult burn survivors: A National Institute on Disability, Independent Living, and Rehabilitation Research Burn Model System Study

BACKGROUND

Patient-reported outcomes are important for understanding recovery after burn injury, benchmarking service delivery and measuring the impact of interventions. Patient-Reported Outcomes Measurement Information System (PROMIS)-29 domains have been validated for use among diverse populations though not among burn survivors. The purpose of this study was to examine validity and reliability of PROMIS-29 scores in this population.

METHODS

The PROMIS-29 scores of physical function, anxiety, depression, fatigue, sleep disturbance, ability to participate in social roles, and pain interference were evaluated for validity and reliability in adult burn survivors. Unidimensionality, floor and ceiling effects, internal consistency, and reliability were examined. Differential item functioning was used to examine bias with respect to demographic and injury characteristics. Correlations with measures of related constructs (Community Integration Questionnaire, Satisfaction with Life Scale, Post-Traumatic Stress Checklist-Civilian, and Veteran's Rand-12) and known-group differences were examined.

RESULTS

Eight hundred and seventy-six burn survivors with moderate to severe injury from 6 months to 20 years postburn provided responses on PROMIS-29 domains. Participants' ages ranged from 18 years to 93 years at time of assessment; mean years since injury was 3.4. All PROMIS domain scores showed high internal consistency (Cronbach's α = 0.87-0.97). There was a large ceiling effect on ability to participate in social roles (39.7%) and physical function (43.3%). One-factor confirmatory factor analyses supported unidimensionality (all comparative fit indices >0.95). We found no statistically significant bias (differential item functioning). Reliability was high (>0.9) across trait levels for all domains except sleep, which reached moderate reliability (>0.85). All known-group differences by demographic and clinical characteristics were in the hypothesized direction and magnitude except burn size categories.

CONCLUSION

The results provide strong evidence for reliability and validity of PROMIS-29 domain scores among adult burn survivors. Reliability of the extreme scores could be increased and the ceiling effects reduced by administering PROMIS-43, which includes six items per domain, or by administering by computerized adaptive testing.

Beyond the acute phase: understanding relationships among cardio-respiratory response to exercises, physical activity levels, and quality of life in children after burn injuries

The long-term cardiorespiratory function in burn-injured children can be jeopardized due to complications brought on by the injury. This study sought to assess the cardio-respiratory responses to maximal exercise in children who sustained a burn injury and explore the relationships among cardio-respiratory response, physical activity levels (PALs), and health-related quality of life (HRQL). Forty-five burn-injured children (age:13.89±2.43 years; duration since burn-injury: 3.13±0.93 years) and 52 age- and gender-matched healthy children (14.15±2.27 years) participated in this study. Both cohorts were evaluated for the maximal exercise capacity [defined by peak oxygen uptake (VO2peak), maximum heart rate (HRmax), minute ventilation (VE), ventilatory equivalent (VEq), respiratory rate (RR), and respiratory exchange ratio (RER)], PALs, and HRQL. The burn-injured children had significantly lower VO2peak (P=.0001) and VE (P=.003) and higher VEq (P<.0001) and RR (P=.007) than their healthy controls, indicating less efficient cardio-respiratory capacity. However, the HRmax (P=.092) and RER (P=.251) were similar. The burn-injured children reported significantly lower PALs (P=.014) and HRQL (P<.0001). The PALs [r (95%CI) = 0.411 (0.132 to 0.624); P = .005] and HRQL [r (95%CI) = 0.536 (0.284 to 0.712); P = .0001] were significantly correlated with the cardio-respiratory capacity represented by VO2peak in burn-injured group. The variations in VO2peak explained ⁓ 17% and 28.7% of the variations in PALs and HRQL, respectively. In conclusion, the cardio-respiratory efficiency of the burn-injured children may remain limited, even up to a few years following the injury. The limited cardio-respiratory capacity account in part for the reduced PALs and HRQL.

Evaluation of the psychometric properties of the burn specific health scale-brief: A National Institute on Disability, Independent Living, and Rehabilitation Research Burn Model System Study

OBJECTIVE

The Burn Specific Health Scale-Brief (BSHS-B) is a commonly used burn specific health outcome measure that includes 40 items across nine subscales. The objective of this study was to use both classical and modern psychometric methods to evaluate psychometric properties of the BSHS-B.

METHODS

Data were collected post burn injury by a multisite federally funded project tracking long term outcomes. We examined dimensionality, local dependence, item fit, and functioning of response categories, homogeneity, and floor and ceiling effects. Items were fit to Item Response Theory models for evaluation.

RESULTS

A total of 653 adults with burn injury completed the BSHS-B. Factor analyses supported unidimensionality for all subscales, but not for a total score based on all 40 items. All nine of the subscales had significant ceiling effects. Six item pairs displayed local dependence suggesting redundance and 11 items did not fit the Item Response Theory models. At least 15 items have too many response options.

CONCLUSIONS

Results identified numerous psychometric issues with the BSHS-B. A single summary score should never be used for any purpose. Psychometric properties of the scale need to be improved by removing redundant items, reducing response categories and modifying or deleting problematic items. Additional conceptual work is needed to, at a minimum, revise the work subscale and optimally to revisit and clearly define the constructs measured by all the subscales. Additional items are needed to address ceiling effects.

Study of clinical pattern of limb loss in electrical burn injuries

INTRODUCTION

Electrical burn injuries are devastating and cause not only loss of life but also severe disabilities in the form of limb loss. Increase in urbanization, industrialization and overcrowding has led to an increase in electric injuries.

MATERIAL AND METHODS

The study was prospective in nature evaluating electric burns and studied the pattern of limb loss for a duration of 18 months from October 2016 to March 2018. Parameters recorded were demographic data, clinical data regarding the electrical injuries, complications, and outcomes.

RESULTS

Male patients made up 85.3% of cases. Mean TBSA was 24.76 ± 19.18%. Mean age was 27.59 ± 13.73 years. Pediatric patients made up 17%. High voltage burns constituted 68.2 %. Electric contact burn was the most common type making up 49.5% of cases. The most common cause was occupational (38.9%). A fasciotomy was required in 22% of cases with an amputation rate of 38% (209 out of 550). There were 190 major amputations and 106 minor amputations. Overall, the right upper limb amputations were twice as common as the left. The ratio of upper limb: lower limb amputation was 4:1. Fifty patients (23.9%) required revision amputation. The age group 11 to 30 years made up 55.5% of amputations. There was no statistical difference in amputation rates between males (31.31%) and females (41.97%). In patients with TBSA less than 25% amputation rate was 47.77% as compared to patients with more than 25% TBSA, 19.47% (p<0.001). Most amputations occurred due to electric contact burns (74.16%). In the high voltage group, 46.1% underwent amputation vs low voltage group -20.6% (p<0.001). Overall mortality rate was 12.7%. Three hundred patients (55%) had low level of awareness regarding consequences of electric injury. Thirty one percent had medium level of awareness and only 14 % had high level of awareness. There was a significant correlation between education level and awareness in adult patients (p<0.001). Seventy percent of persons with occupational injuries used only footwear and no other protective equipment.

CONCLUSION

Increasing public awareness, safety measures at workplaces are measures that will help reducing electrical burns which reduce limb and life loss.

A Cross-sectional Survey of Health Professionals Across Australia and New Zealand to Determine What Outcome Measures Are Important From a Clinical Perspective Post Hand Burn Injury

Outcome measures are used in healthcare to evaluate clinical practice, measure efficiencies and to determine the quality of health care provided. The Burns Trauma Rehabilitation: Allied Health Practice Guidelines advocates for the collection of outcome measures post burn injuries across different time points. These guidelines recommend multiple tools which can be utilized when measuring outcomes post burn injuries. The aim of this study was to gather information from specialist clinicians regarding their clinical practice and the outcome measurement tools used post hand burn injuries. This cross-sectional study used a survey design to collect data at one given point in time across a sample population. A total of 43 clinical specialists allied health professionals responded to the survey. Respondents indicated that their patients considered hand dexterity was the most important outcome. Three months post burn injury was the most common timepoint for measurement (n = 31, 72.1%) followed by six months (n = 27, 62.8%). Patient report of hand function (n = 42, 97.7%) and observation (n = 41, 95.3%) were the most frequently reported assessment methods. The Jamar Dynamometer (n = 40, 93%), goniometer (n = 39, 90.7%) and pinch gauge (n = 36, 83.7) were the most frequency cited assessment tools. The findings of this study suggest that clinical specialist allied health collect some outcome measures in their routine practice. Based on the respondent's perceptions of barriers when using outcome measures and lack of reliable/validated tools to measure hand burn outcomes, there is a need for further studies in this area.

Contracture Severity at Hospital Discharge in Children: A Burn Model System Database Study

Contractures can complicate burn recovery. There are limited studies examining the prevalence of contractures following burns in pediatrics. This study investigates contracture outcomes by location, injury, severity, length of stay, and developmental stage. Data were obtained from the Burn Model System between 1994 and 2003. All patients younger than the age of 18 with at least one joint contracture at hospital discharge were included. Sixteen areas of impaired movement from the shoulder, elbow, wrist, hand, hip, knee, and ankle joints were examined. Analysis of variance was used to assess the association between contracture severity, burn size, and length of stay. Age groupings were evaluated for developmental patterns. A P value of less than .05 was considered statistically significant. Data from 225 patients yielded 1597 contractures (758 in the hand) with a mean of 7.1 contractures (median 4) per patient. Mean contracture severity ranged from 17% (elbow extension) to 41% (ankle plantarflexion) loss of movement. Statistically significant associations were found between active range of motion loss and burn size, length of stay, and age groupings. The data illustrate quantitative assessment of burn contractures in pediatric patients at discharge in a multicenter database. Size of injury correlates with range of motion loss for many joint motions, reflecting the anticipated morbidity of contracture for pediatric burn survivors. These results serve as a potential reference for range of motion outcomes in the pediatric burn population, which could serve as a comparison for local practices, quality improvement measures, and future research.

Burn Survivors' Experiences of the Ongoing Challenges after Discharge in South Korea: A Qualitative Study

OBJECTIVE

To help burn survivors during the recovery time after discharge, healthcare professionals need to understand their experiences and care requirements. However, little is known about the experience of burn survivors after discharge in South Korea. This study aims to explore their experiences in a community setting.

METHODS

Using a qualitative descriptive format, data were collected by semistructured interview from 10 patients who had sustained major burns. Each interview was based on a protocol of 60 to 90 minutes' duration and used a qualitative content analysis.

RESULTS

Three themes were identified in the analysis: (1) ongoing distressing symptoms and the unpredictability of hypertrophic scars, (2) difficulties in reintegration into society, and (3) burden of health expenditure.

CONCLUSIONS

Several participants expressed consistent difficulties with distressing symptoms such as wound pain, pruritus, sleep disturbances, and unpredictable scar and symptom changes. Survivors further described the financial burden associated with high expenditures from nonreimbursable rehabilitation expenses, and the high cost incurred with consistent skin care. By providing support based on their needs, appropriate interventions would be more readily available for burn survivors.

Contemporary Aspects of Burn Care

The past one hundred years have seen tremendous improvements in burn care, allowing for decreased morbidity and mortality of this pathology. The more prominent advancements occurred in the period spanning 1930-1980; notably burn resuscitation, early tangential excision, and use of topical antibiotic dressings; and are well documented in burn literature. This article explores the advancements of the past 40 years and the areas of burn management that are presently topics of active discussion and research.

Health-Related Quality of Life and Its Associated Factors Among Burn Patients at Governmental Referral Hospitals of Amhara Regional State, Northwest Ethiopia, 2020: Institutional-Based Cross-Sectional Study

INTRODUCTION

Burns can have a considerable negative impact on physical and psychosocial functioning that affects the quality of life. The physical and psychological manifestations may compromise the quality of life of burned patients. The aim is to assess health-related quality of life and associated factors among burn patients at Amhara regional state governmental referral hospitals, Northwest Ethiopia, 2020.

METHODS

Institution-based cross-sectional study was conducted from June 01 to July 15, 2020, in Amhara National regional state governmental referral hospitals. Systematic random sampling technique was used, and data were collected using structured Burn Specific Health Scale Brief Questionnaire through face-to-face interview and document review from patients time since burn 15 days and above. Data were entered into Epidata, and analysis was done by SPSS version 25. Descriptive statistics were computed, and binary logistic regression analysis was used to determine the association between the dependent and independent variables. Variables with a p-value of ≤0.05 in the multivariable analysis were considered statistically significant.

RESULTS

Of 423 study participants, 95.7% responded completely. Among the respondents, 58.8% (group mean and median of 18.38 and 21) for physical domain and 57% (group mean and median of 44.73 and 53) for generic domains had a poor health-related quality of life. Overall poor health-related quality of life was 57.5% with a mean of 63.12. Third-degree burn, exposed burnt body part, total body surface area burned ≥20%, having an amputation and having a co-morbid illness with (P = 0.001) were associated with poor health-related quality of life.

CONCLUSION AND RECOMMENDATION

This study revealed that more than half of the burn survivors had poor health-related quality of life. There shall be strengthened long-term physical and psychosocial domains (generic) intervention for burn survivors by giving more concern for those with the identified risk factors.

Suicidality After Burn Injuries: A Systematic Review

Burn survivors may be at increased risk for suicide due to the nature of their injury and psychiatric comorbidities. The purpose of this review is to assess the evidence as to the prevalence of suicidal ideations and behaviors (attempts and completed suicides) in burn survivors as well as evaluate risk and protective factors. PubMed, EMBASE, CINAHL, Cochrane, PsycINFO, and Web Science databases were searched using search terms regarding suicide, suicidality, and burn. Fourteen full-text manuscripts and two published abstracts were included in the review. Overall, burn survivors demonstrate elevated suicidal ideations and a higher lifetime prevalence of suicide attempts compared to the general population. There is mixed evidence as to rates of completed suicide postburn injury, though rates appear to be relatively low. Risk factors include pain at discharge, perceived level of disfigurement, premorbid psychiatric comorbidities, and past suicide attempts. Results of this systematic review shed light on the scarcity of data on rates of suicidality among burn survivors, which is surprising given the multiple risk factors burn survivors possess including chronic pain, sleep disturbances, history of substance abuse, posttraumatic stress disorder, social isolation, and depression which are linked to suicidality in the general population. Suicide risk screening should be included as an integral part of burn survivors' care, and more research is needed to better understand the magnitude of this phenomenon and offer targeted interventions to vulnerable individuals.

Perceived Value of a Knowledge Translation Intervention Designed to Facilitate Burn Survivors' Work Reintegration

Returning to work can be challenging for burn survivors. Approximately 28% never return to any form of employment, resulting in lower health-related quality of life. Open communication has been identified as a facilitator for return to work (RTW). To ease the RTW process and promote communication with coworkers and employers a knowledge translation (KT) intervention was developed for burn survivors. Following its implementation, the impact on the RTW process was evaluated. This study was a cross-sectional, mixed methods study where burn survivors included in the KT intervention were compared with a control group. Control group participants were selectively invited so that the two groups' mean age, sex, and percent total body surface area burned were similar. Semistructured interviews gathered information about their RTW process and outcomes. Qualitative data were analyzed through thematic analysis and quantitative data were summarized and compared using Mann-Whitney tests. Overall, both groups were satisfied with their RTW process. Participants from the control group identified more barriers related to support received, particularly at work, and reported more psychological symptoms such as posttraumatic stress disorder, self-consciousness, and discomfort with questions. Many participants from the KT group indicated the KT intervention gave them tools and information to provide others with a better understanding of their lived experience. It is possible that the KT intervention facilitated more open communication by empowering burn survivors to explain their situation on their own, thus reducing the prevalence of social and psychological barriers by allowing them to self-advocate for more support.

Effect of physical therapy rehabilitation program combined with music on children with lower limb burns: A twelve-week randomized controlled study

BACKGROUND

Burn injuries cause significant physical impairments that need comprehensive rehabilitation and coordination with the acute burn care team. Music had been shown to increase positive mood during exercise, which may result in motivation for participation in exercise programs. The current study aimed to evaluate the effect of physical therapy rehabilitation program combined with music therapy on children with lower limb burns.

METHODS

A twelve-week randomized controlled study including thirty pediatrics with lower limb burns. They were randomly assigned into two equal groups, 15 children per each. Group A received a physical therapy rehabilitation program combined with music therapy in addition to routine medical care. However, Group B received a physical therapy rehabilitation program without music therapy. Assessment of pain was by visual analogue scale (VAS), assessment of the range of motion (ROM) by goniometer, and gait assessed by GAIT Rite. The evaluation was carried before and after the interventions.

RESULTS

Before starting the study, no significant differences were detected between the two study groups (p < 0.05). The study results reported statistically significant improvement in VAS, ROM, and GAIT Rite in both groups after the intervention (p < 0.05). Group A showed greater improvement than group B in all outcome measures (p < 0.05).

CONCLUSION

Physical therapy program combined with music therapy is an effective and safe modality for improving pain, range of motion, and gait parameters in pediatrics with lower limb burn. Also, physical therapy combined with music therapy is more effective than physical therapy alone in the treatment of pediatrics with lower limb burns.

A Comparison of Contracture Severity at Acute Discharge in Patients With and Without Heterotopic Ossification: A Burn Model System National Database Study

This study assesses the association between heterotopic ossification and upper extremity contracture by comparing goniometric measured active range of motion outcomes of patients with and without heterotopic ossification. Data were obtained from the Burn Model System National Database between 1994 and 2003 for patients more than 18 years with elbow contracture at acute discharge. Absolute losses in elbow range of motion were compared for those with and without radiologic evidence of heterotopic ossification (location undefined) and were further examined by burn size subgroups using Wilcoxon rank-sum test. Differences in elbow range of motion were estimated using regression models, adjusted for demographic and clinical variables. Loss of range of motion of shoulder, wrist, forearm, and hand were also compared. From 407 instances of elbow contracture, the subjects with heterotopic ossification were found to have greater median absolute loss of elbow flexion among all survivors (median 50° [IQR 45°] vs 20° [30°], P < .0001), for the 20 to 40% total body surface area burn subgroup (70° [20°] vs 20° [30°], P = .0008) and for the >40% subgroup (50° [45°] vs 30° [32°], P = .03). The adjusted estimate of the mean difference in the absolute loss of elbow flexion between groups was 23.5° (SE ±7.2°, P = .0013). This study adds to our understanding of the potential effect of heterotopic ossification on upper extremity joint range of motion, demonstrating a significant association between the presence of heterotopic ossification and elbow flexion contracture severity. Further study is needed to determine the functional implications of heterotopic ossification and develop treatment protocols.

Nonsurgical Management of Hypertrophic Scars: Evidence-Based Therapies, Standard Practices, and Emerging Methods

Hypertrophic scars, resulting from alterations in the normal processes of cutaneous wound healing, are characterized by proliferation of dermal tissue with excessive deposition of fibroblast-derived extracellular matrix proteins, especially collagen, over long periods, and by persistent inflammation and fibrosis. Hypertrophic scars are among the most common and frustrating problems after injury. As current aesthetic surgical techniques become more standardized and results more predictable, a fine scar may be the demarcating line between acceptable and unacceptable aesthetic results. However, hypertrophic scars remain notoriously difficult to eradicate because of the high recurrence rates and the incidence of side effects associated with available treatment methods. This review explores the various treatment methods for hypertrophic scarring described in the literature including evidence-based therapies, standard practices, and emerging methods, attempting to distinguish those with clearly proven efficiency from anecdotal reports about therapies of doubtful benefits while trying to differentiate between prophylactic measures and actual treatment methods. Unfortunately, the distinction between hypertrophic scar treatments and keloid treatments is not obvious in most reports, making it difficult to assess the efficacy of hypertrophic scar treatment.

Orofacial rehabilitation after severe orofacial and neck burn: Experience in a Brazilian burn reference centre

OBJECTIVE

To quantify the benefits of a functional oral rehabilitation program for impairment caused by full thickness orofacial and neck burns, comparing the effects of early and late intervention.

METHODS

An observational cross-sectional study was conducted in a burn reference center over a two-year period. Patients with full thickness orofacial and neck burns were divided in two groups: Group 1 was composed by 14 patients who began the rehabilitation program 3-12 months after the burn injury; Group 2 was composed by 15 patients who began the rehabilitation program more than 12 months after the burn injury. Treatment was based on current strategies of non-surgical exercises for orofacial contracture management. Outcome measurements included an oral motor clinical evaluation and the assessment of the mandibular range of movement.

RESULTS

The functional rehabilitation program was effective in reestablishing the oral motor functions (i.e deficits reduced to approximately 15% when compared to the optimal possible scores) and in restoring horizontal mouth opening dimensions, with more than 70% of the patients presenting measurements within the expected normal limits at the end of treatment. Our results did not indicate differences in performance between the group of patients in neither set of assessments, i.e. pre and post treatment (p > 0.05).

CONCLUSION

The results of this study indicate that non-invasive orofacial contracture management is effective for patients with orofacial and neck burns, including those with long term sequelae.

Healing of deep dermal burns by allogeneic mesenchymal stromal cell transplantation

BACKGROUND

Deep dermal and full-thickness burns are not only difficult to treat, but they are also associated with significant morbidity and mortality. Recent reports have proposed the use of mesenchymal stromal cells (MSCs) for inducing tissue repair in burn injuries.

OBJECTIVE

We aim to evaluate the effect of allogeneic MSC transplantation on full-thickness burns with delayed healing.

MATERIAL AND METHODS

This study includes five patients with AB B/B burns. All patients received conservative treatments, including cleaning, debridement of necrotic tissue, and silver based dressing on the burn wounds. Cryopreserved allogeneic MSCs were thawed and rapidly expanded and used for application in burned patients. MSCs were implanted into preclotted platelet-rich plasma onto the surface of burn wounds.

RESULTS

All treated burn wounds showed early granulation tissue and rapid re-epithelialization after MSC transplantation. Healing took between 1 and 5 months after MSC transplantation. Repair of burn wounds was associated with slight discoloration of the regenerated skin without hypertrophic scarring or contractures.

CONCLUSION

Our results provide evidence of healing in deep- and full-thickness burns by allogeneic MSC transplantation. Rapid healing of burn patients, after MSC transplantation, improves their quality of life and reduces the length of hospitalization. Future studies incorporating a larger number of patients may confirm the results obtained in this work.

Severe Burn Injury Progression and Phasic Changes of Gene Expression in Mouse Model

Patients with severe burns are susceptible to infectious complications including burn-site infections and sepsis. The purpose of this study was to explore the pathologic development of burn injury in a mouse model and to screen genes dysregulated at different time points on the basis of gene expression microarrays. Differential expression analysis identified a total 223 genes that related to only time progression independent of burn injury and 214 genes with aberrant expression due to burn injury. Weighted gene co-expression network analysis (WGCNA) of the 214 genes obtained seven gene modules which named as red, blue, turquoise, green, brown, yellow, and gray module, and the blue module was found to be significantly associated with severe burn injury progression, and in which several genes were previously reported being associated with inflammation and immune response, such as interleukin IL-6, IL-8, and IL-1b. Functional enrichment analysis indicated significant enrichment of biological processes that related to metabolism and catabolism, and pathways of proteasome, notch signaling and cell cycle. This result supports a phase progression of severe burn with gene expression changes and interpretation of biological processes in mouse.

Introduction to the NIDILRR Burn Model System (BMS) Program: Selected Findings II

A special supplement to the Archives of Physical Medicine and Rehabilitation in 2007 reported selected findings of research from the first 13 years of the BMS Centers and Database Coordinating Center. This special supplement is the second such effort and reports on the growth of the BMS National Longitudinal Database (BMS NDB) since that time and select new research findings from the BMS centers.

The Impact of Introducing a Physical Medicine and Rehabilitation Consultation Service to an Academic Burn Center

Prior retrospective studies suggest that physical medicine and rehabilitation (PM&R) acute care consultation improves outcome and reduces acute care length of stay (ACLOS) in trauma patients. There have not been prospective studies to evaluate this impact in burn patients. This cohort study compared outcomes before and after the introduction of a PM&R consultation service to the acute burn program, and the inpatient rehabilitation program, at a large academic hospital. The primary outcome measures were length of stay (LOS) in acute care and during subsequent inpatient rehabilitation. For the acute care phase, there were 194 patients in the preconsultation group and 114 who received a consultation. There was no difference in age, Baux score, or LOS in these patients. For the rehabilitation phase, there were 109 patients in the prephysiatrist group and 104 who received PM&R care. The LOS was significantly shorter in the latter group (24 days vs 30 days, P = .002). Functional independence measure (FIM) change, unexpected readmission, and discharge destination were not significantly different. The addition of a burn physiatrist did not influence ACLOS. However, there was a significant reduction in inpatient rehabilitation LOS.

Deferiprone has anti-inflammatory properties and reduces fibroblast migration in vitro

Normal wound healing is a highly regulated and coordinated process. However, tissue injury often results in inflammation with excessive scar tissue formation after 40-70% of operations. Here, we evaluated the effect of the iron chelator deferiprone on inflammation and the migration of primary nasal fibroblasts and primary human nasal epithelial cells (HNECs) in vitro. The cytotoxicity of deferiprone was examined by the lactate dehydrogenase assay on primary nasal fibroblasts and air-liquid interface (ALI) cultures of HNECs. Wound closure was observed in scratch assays by using time-lapse confocal scanning laser microscopy. Interleukin-6 (IL-6) and type I and III collagen protein levels were determined by ELISA. Intracellular Reactive Oxygen Species (ROS) activity was measured by utilizing the fluorescent probe H2DCFDA. Deferiprone at 10 mM concentration was non-toxic to primary fibroblasts and HNECs for up to 48 hours application. Deferiprone had significant dose-dependent inhibitory effects on the migration, secreted collagen production and ROS release by primary nasal fibroblasts. Deferiprone blocked Poly (I:C)-induced IL-6 production by HNECs but did not alter their migration in scratch assays. Deferiprone has the potential to limit scar tissue formation and should be considered in future clinical applications.

Surgical treatment of postburn heterotopic ossification around the elbow: Three case reports

RATIONALE

Heterotopic ossification (HO), which is defined as the formation of new bone in tissues that do not normally ossify, is an infrequent yet debilitating complication of burns. Herein, we report three patients who suffered from elbow HO after burn injury due to a dust explosion event. This is a case report that includes the most cases involved in a single mass casualty incident in the presented literature.

PATIENT CONCERNS

Case 1: A 28-year-old man presented with second-to-third degree 88% total body surface area (TBSA) burns after the explosion event. He complained of decreased progressive bilateral elbow range of motion (ROM) for 1.5 months after the burn injury.Case 2: A 28-year-old woman presented with second-to-third degree 50% TBSA burns and complained of decreased progressive bilateral elbow ROM with intolerable pain on elbow extension for 1 month after the burn injury.Case 3: A 22-year-old man presented with second-to-third degree 90% TBSA burns and complained of significantly decreased left elbow ROM with intolerable pain 5 months after the burn injury.

DIAGNOSIS

The follow-up radiograph of the symptomatic elbow of these three patients revealed heterotopic ossification formation. Three-dimensional reconstruction computed tomography performed preoperatively showed that HO mainly affected the humeroulnar joint.

INTERVENTIONS

We treated all three patients with surgical elbow HO resection and ulnar nerve transposition, followed by immediate passive ROM exercise since postoperative day 1 and continuous physical therapy.

OUTCOMES

In case 1, the documented ROM gain on the last follow-up (18.5 months after surgery) was 30° in the right elbow and 118° in the left elbow. In case 2, the follow-up time was 21 months and the documented ROM gain on the last follow-up was 120° in the right elbow and 90° in the left elbow. In case 3, the follow-up time was 20 months and the documented left elbow ROM gain on the last follow-up was 40°.

LESSONS

We discuss our experience of treating postburn HO and review the recent literature. The postburn HO treatment results of early surgical excision combined with immediate postoperative physical therapy were satisfactory.

Ethanol and Methanol Burn Risks in the Home Environment

Biofuel heaters and fireplaces have in recent years been introduced for indoor and outdoor use. Due to their simplicity, they are usually equipped with few or no safety features. Worldwide, incidents resulting in major skin burn injury and long hospitalization periods have occurred when using such biofuel units. The present study analyses the characteristics of the liquids ethanol and methanol to get a scientific background for understanding related accidents. The comparably heavy vapors, especially from ethanol, may generate a pillow of combustible gas in the vicinity of the unit, particularly in quiescent indoor air conditions. It is also revealed that these fuels represent a potential severe risk, since the equilibrium vapor pressures are close to the stoichiometric fuel–air composition at normal room temperatures. Selected incidents were reviewed to understand the mechanisms involved when severe burns were received by the users. It turns out that the most severe incidents were related to refilling operations and included ignition of the fuel container vapor phase. When ignited, the container gas phase expansion propelled burning fuel from the bottle or container onto the user or other persons in the vicinity. Similar incidents involving refilling methanol for chemistry demonstrations and ethanol for endodontic (dentistry) treatment were also studied and it was shown that these accidents followed similar accident mechanisms. It may be concluded that the main contributors to burn risk are the near-stoichiometric vapor pressure of these liquids at room temperature and the close proximity of the fuel container to burning fuel. Research needs and possible technical barriers are suggested to reduce this risk for the future.

Effect of extracorporeal shock wave therapy on improving burn scar in patients with burnt extremities in Isfahan, Iran

Background:

Pathologic scarring is a common problem after burn injury that has functional and esthetic limitations. Conservative and surgical treatments available for these scars are not always satisfactory. Extracorporeal shock wave therapy (ESWT) is a noninvasive modality that has proven positive effects on burn scars and wound healing in few studies. This study was conducted to evaluate the effects of ESWT on improving burn scar in extremities.

Materials and Methods:

This study was a prospective quasi-experimental on burn patients with burn scar in their extremities that underwent ESWT sessions once a week for 6 weeks. For evaluating pain and itching, visual analog scale (VAS) and for scar appearance, Vancouver Scar Scale (VSS) were used. These scales were measured and compared at the beginning of the treatment, at the end of the treatment, and 1 and 3 months after the end of the intervention.

Results:

In this study, 17 patients were treated with ESWT with a mean age of 37.94 ± 7.25 years that 47.1% of them were male. The mean of VAS score for pain and itching and VSS score were decreased significantly after the treatment and during follow-ups (All P < 0.001).

Conclusion:

ESWT can improve the pain, itching, and appearance of the burn scar in human extremities in burn patients.
