RESUMO

Severe burn leads to substantial skeletal muscle wasting that is associated with adverse outcomes and protracted recovery. The purpose of our study was to investigate muscle tissue homeostasis in response to severe burn. Muscle biopsies from the right m. lateralis were obtained from 10 adult burn patients at the time of their first operation. Patients were grouped by burn size (total body surface area of <30% vs ≥30%). Muscle fiber size and factors of cell death and muscle regeneration were examined. Muscle cell cross-sectional area was significantly smaller in the large-burn group (2174.3 ± 183.8 µm2 vs 3687.0 ± 527.2 µm2, P = .04). The expression of ubiquitin E3 ligase MuRF1 and cell death downstream effector caspace 3 was increased in the large-burn group (P < .05). No significant difference was seen between groups in expression of the myogenic factors Pax7, MyoD, or myogenin. Interestingly, Pax7 and proliferating cell nuclear antigen (PCNA) expression in muscle tissue were significantly correlated to injury severity only in the smaller-burn group (P < .05). In conclusion, muscle atrophy after burn is driven by apoptotic activation without an equal response of satellite cell activation, differentiation, and fusion.

RESUMO

Delays to the operating room (OR) or discharge (DC) lead to longer lengths of stay and increased costs. Surprisingly, little work has been done to quantify the number and cost of delays for inpatients to the OR, and to DC to outpatient status. They reviewed their burn admissions to determine how often a patient experiences delays in healthcare delivery. Data for all burn admissions were prospectively collected from 2014 to 2016. A quality improvement filter was created to define acceptable parameters for patient throughput. Every hospital day was labeled as 1) No delay, 2) Operation, 3) Delay to the OR, or 4) Delay to DC. They had 1633 admissions: 432 ICU admissions (26%) and 1201 floor admissions (74%). Six hundred fifteen patients (37.7%) received an operation. Patients with delays included 331 with OR delays (20.3%) and 503 with DC delays (30.8%). Average delay days included (Mean ± SD): OR delay days = 4.7 ± 6.2 and DC delay days = 4.1 ± 4.4. Total number of hospital days was 13,009, divided into 1616 OR delay days (12%) and 2096 DC delay days (16%). Significant OR delays were due to patient unstable for OR (n = 387 [24%]), OR space availability (n = 662 [41%]), indeterminate wound depth (n = 437 [27%]), and donor site availability (n = 83 [5%]). Significant DC delays were due to medical goals not reached (n = 388 [19%]), pain control and wound care (n = 694 [33%]), PT/OT clearance (n = 168 [8.0%]), and DC placement delays (n = 754 [36%]). Costs for OR and DC delays ranged between US$1,000,000 and US$5,000,000. Costs of increasing OR capacity and/or additional social work ancillary staff can be justified through millions of dollars of savings annually.

RESUMO

Acute kidney injury (AKI) is a common and morbid complication in patients with severe burn. The reported incidence of AKI and mortality in this population varies widely due to inconsistent and changing definitions. They aimed to examine the incidence, severity, and hospital mortality of patients with AKI after burn using consensus criteria. This is a retrospective cohort study of adults with thermal injury admitted to the Parkland burn intensive care unit (ICU) from 2008 to 2015. One thousand forty adult patients with burn were admitted to the burn ICU. AKI was defined by KDIGO serum creatinine criteria. Primary outcome includes hospital death and secondary outcome includes length of mechanical ventilation, ICU, and hospital stay. All available serum creatinine measurements were used to determine the occurrence of AKI during the hospitalization. All relevant clinical data were collected. The median total body surface area (TBSA) of burn was 16% (IQR: 6%-29%). AKI occurred in 601 patients (58%; AKI stage 1, 60%; stage 2, 19.8%; stage 3, 10.5%; and stage 3 requiring renal replacement therapy [3-RRT], 9.7%). Patients with AKI had larger TBSA burn (median 20.5% vs 11.0%; P < .001) and more mechanical ventilation and hospitalization days than patients without AKI. The hospital death rate was higher in those with AKI vs those without AKI (19.7% vs 3.9%; P < .001) and increased by each AKI severity stage (P trend < .001). AKI severity was independently associated with hospital mortality in the small burn group (for TBSA ≤ 10%: stage 1 adjusted OR 9.3; 95% CI, 2.6-33.0; stage 2-3 OR, 35.0; 95% CI, 9.0-136.8; stage 3-RRT OR, 30.7; 95% CI, 4.2-226.4) and medium burn group (TBSA 10%-40%: stage 2-3 OR, 6.5; 95% CI, 1.9-22.1; stage 3-RRT OR, 35.1; 95% CI, 8.2-150.3). AKI was not independently associated with hospital death in the large burn group (TBSA > 40%). Urine output data were unavailable. AKI occurs frequently in patients after burn. Presence of and increasing severity of AKI are associated with increased hospital mortality. AKI appears to be independently and strongly associated with mortality in patients with TBSA ≤ 40%. Further investigation to develop risk-stratification tools tailoring this susceptible population is direly needed.

RESUMO

Acute kidney injury (AKI) after severe burns is historically associated with a high mortality. Over the past two decades, various modes of renal replacement therapy (RRT) have been used in this population. The purpose of this multicenter study was to evaluate demographic, treatment, and outcomes data among severe burn patients treated with RRT collectively at various burn centers around the United States. After institutional review board approval, a multicenter observational study was conducted. All adult patients aged 18 or older, admitted with severe burns who were placed on RRT for acute indications but not randomized into a concurrently enrolling interventional trial, were included. Across eight participating burn centers, 171 subjects were enrolled during a 4-year period. Complete data were available in 170 subjects with a mean age of 51 ± 17, percent total body surface area burn of 38 ± 26% and injury severity score of 27 ± 21. Eighty percent of subjects were male and 34% were diagnosed with smoke inhalation injury. The preferred mode of therapy was continuous venovenous hemofiltration at a mean delivered dose of 37 ± 19 (ml/kg/hour) and a treatment duration of 13 ± 24 days. Overall, in hospital, mortality was 50%. Among survivors, 21% required RRT on discharge from the hospital while 9% continued to require RRT 6 months after discharge. This is the first multicenter cohort of burn patients who underwent RRT reported to date. Overall mortality is comparable to other critically ill populations who undergo RRT. Most patients who survive to discharge eventually recover renal function.

RESUMO

OBJECTIVE: Fractional laser therapy is a new treatment with potential benefit in the treatment of burn scars. We sought to determine patient satisfaction after burn scar treatment with the Erbium-Yag laser. METHODS: We performed a telephone survey of all patients who underwent fractional resurfacing of burn scars with the Erbium-Yag 2940 wavelength laser at Parkland Hospital from 01/01/2016 to 05/01/2017. Subjects were asked to rate their satisfaction with their scars' after treatment characteristics on a scale from 1 (completely unsatisfied) to 10 (completely satisfied). Subjects were also asked to assess their treatment response using the UNC 4P Scar Scale before and after treatment. RESULTS: Sixty-four patients underwent 156 treatments. A survey response rate of 77% (49/64) was seen (age: 36.8+21 years; surface area treated=435+326cm2; 35% of burn scars were >2 years old; mean scar age of 1.02+0.4 years). Overall, 46/49 (94%) of patients reported some degree of scar improvement after treatment. Patient satisfaction scores were 8.3+2.3. Number of laser treatments included: 1 (31%), 2 (33%), 3 (18%), 4(10%), >5 (8%). Treatment depth, scar age, and number of laser procedures were not significant predictors of satisfaction or UNC 4P Scar scores. The paired t-test showed a significant reduction on each of the UNC 4P Scar scale items (pain, pruritus, pliability, paresthesia). One subject reported that she felt that the laser treatment made her scar worse (2%). CONCLUSION: Burn patients treated with the Erbium-Yag laser are highly satisfied with changes in their burn scars.

RESUMO

Previously, they identified that 60 per cent of their facility's total operative time is nonoperative. They performed a review of their operating room to determine where inefficiencies exist in nonoperative time. Live video of operations performed in a burn operating room from June 23, 2017 to August 16, 2017 was prospectively reviewed. Preparation (end of induction to procedure start) and turnover (patient out of room to next patient in room) were divided into the following activities: 1) Preparation: remove dressing, position patient, clean patient, drape patient, and 2) Turnover: clean operating room, scrub tray setup, anesthesia setup. Ideal preparation time was calculated as the sum of time needed to perform preparation activities consecutively. Ideal turnover time was calculated as the sum of time needed to clean the operating room and to set up either the scrub tray or anesthesia (the larger of the two times as these can be done in parallel). They reviewed 101 consecutive operations. An average of 2.4 ± 0.8 cases per day were performed. Ideal preparation and turnover time were 16.6 and 30.1 minutes, a 38.3 and 32.5 per cent reduction compared with actual times. Attending surgeon presence in the operating room within 10 minutes of a patient's arrival was found to significantly decrease time to incision by 33 per cent (52.7 ± 14.3 minutes down to 35.7 ± 20.4, P < .0001). A reduction in preparation and turnover time could save $1.02 million and generate $1.76 million in additional revenue annually. Reducing preparation and turnover to ideal times could increase caseload to 4 per day, leading to millions of dollars of savings annually.

RESUMO

Best practices are to conduct an early discussion of goals of care (GoC) after injury in the elderly, but this intervention is inconsistently applied. We hypothesized that a frail appearance was a factor in the decision to conduct a GoC discussion after thermal injury. A retrospective review was performed of all burn survivors aged ≥ 65 years at our American Burn Association (ABA)-verified level 1 burn center between April 02, 2009, and December 30, 2014. Demographic information included age, gender, mechanism of injury, percentage TBSA burned, revised Baux score, patient/physician racial discordance, documented GoC discussion (as defined within the electronic medical record), length of stay (LOS), and disposition. One rater retrospectively assigned clinical frailty scores to patients using the Canadian Study of Health and Aging Criteria, which ranged from 1 (very fit) to 7 (severely frail). Ordinal logistic regression was performed. Demographics for the cohort of 126 subjects were (mean ± SD): age = 75.5 ± 7.7 years, %TBSA burned = 11.9% ± 7.2, revised Baux = 87.8 ± 10.2, hospital LOS (days) = 14.9 ± 13.7, Intensive Care Unit (ICU) LOS (days) = 6.2 ± 1.2, frailty score = 4.1 ± 1.1. Overall, 72% of geriatric survivors had a favorable discharge disposition. GoC discussions occurred in 25% of patients. GoC discussion (OR, 3.42; 95% CI, 1.54-7.60) and an unfavorable disposition (OR, 9.01; 95% CI, 3.91-20.78) were associated with greater predicted odds of receiving a higher ordered frailty score. Our results suggest that, even in the absence of a formal diagnosis, a frail appearance may influence a provider's decision to perform GoC discussions after severe thermal injury.

RESUMO

BACKGROUND: Sepsis and septic shock occur commonly in severe burns. Acute kidney injury (AKI) is also common and often results as a consequence of sepsis. Mortality is unacceptably high in burn patients who develop AKI requiring renal replacement therapy and is presumed to be even higher when combined with septic shock. We hypothesized that high-volume hemofiltration (HVHF) as a blood purification technique would be beneficial in this population. METHODS: We conducted a multicenter, prospective, randomized, controlled clinical trial to evaluate the impact of HVHF on the hemodynamic profile of burn patients with septic shock and AKI involving seven burn centers in the United States. Subjects randomized to the HVHF were prescribed a dose of 70 ml/kg/hour for 48 hours while control subjects were managed in standard fashion in accordance with local practices. RESULTS: During a 4-year period, a total of nine subjects were enrolled for the intervention during the ramp-in phase and 28 subjects were randomized, 14 each into the control and HVHF arms respectively. The study was terminated due to slow enrollment. Ramp-in subjects were included along with those randomized in the final analysis. Our primary endpoint, the vasopressor dependency index, decreased significantly at 48 hours compared to baseline in the HVHF group (p = 0.007) while it remained no different in the control arm. At 14 days, the multiple organ dysfunction syndrome score decreased significantly in the HVHF group when compared to the day of treatment initiation (p = 0.02). No changes in inflammatory markers were detected during the 48-hour intervention period. No significant difference in survival was detected. No differences in adverse events were noted between the groups. CONCLUSIONS: HVHF was effective in reversing shock and improving organ function in burn patients with septic shock and AKI, and appears safe. Whether reversal of shock in these patients can improve survival is yet to be determined. TRIAL REGISTRATION: Clinicaltrials.gov NCT01213914 . Registered 30 September 2010.

RESUMO

Illicit drug use is common among patients admitted following burn injury. The authors sought to evaluate whether drug abuse results in worse outcomes. The National Burn Repository (NBR) was queried for data on all patients with drug testing results available. Outcomes included mortality, hospital length of stay (LOS), intensive care unit (ICU) LOS, and duration of ventilator support. Propensity score weighting was performed to control for age, alcohol use, burn size, gender, and etiology of burn. A total of 20,989 patients had drug screen data available; 11,642 (55.5%) tested positive for at least one drug of abuse. Illicit drug use was associated with a higher proportion of patients with flame burn (53.2 vs 48.4%) and larger average burn size (11.2 vs 9.5% TBSA, P < .001). Attempted suicide was more likely if the patient had used drugs (2.8 vs 1.7%, P < .001). Drug use resulted in longer hospital and ICU LOS (14.2 vs 11.4 and 8.5 vs 5.6 days, P < .001), but did not increase the risk of mortality (5.7 vs 5.2, P = .08). After propensity score weighting, drug use did not affect mortality, hospital LOS, or duration of ventilator support, but did increase the average ICU LOS by 1.2 days (P = .001). Drug use does not affect mortality, hospital LOS, or duration of ventilator support among burned patients. After controlling for burn size, age, mechanism of injury, and gender, patients with a positive drug screen had an average increase in ICU LOS by 1 day.

RESUMO

OBJECTIVE: To determine whether restrictive fluid resuscitation results in increased rates of acute kidney injury (AKI) or infectious complications. BACKGROUND: Studies demonstrate that patients often receive volumes in excess of those predicted by the Parkland equation, with potentially detrimental sequelae. However, the consequences of under-resuscitation are not well-studied. METHODS: Data were collected from a multicenter prospective cohort study. Adults with greater than 20% total burned surface area injury were divided into 3 groups on the basis of the pattern of resuscitation in the first 24 hours: volumes less than (restrictive), equal to, or greater than (excessive) standard resuscitation (4 to 6 cc/kg/% total burned surface area). Multivariable regression analysis was employed to determine the effect of fluid group on AKI, burn wound infections (BWIs), and pneumonia. RESULTS: Among 330 patients, 33% received restrictive volumes, 39% received standard resuscitation volumes, and 28% received excessive volumes. The standard and excessive groups had higher mean baseline APACHE scores (24.2 vs 16, P < 0.05 and 22.3 vs 16, P < 0.05) than the restrictive group, but were similar in other characteristics. After adjustment for confounders, restrictive resuscitation was associated with greater probability of AKI [odds ratio (OR) 3.25, 95% confidence interval (95% CI) 1.18-8.94]. No difference in the probability of BWI or pneumonia among groups was found (BWI: restrictive vs standard OR 0.74, 95% CI 0.39-1.40, excessive vs standard OR 1.40, 95% CI 0.75-2.60, pneumonia: restrictive vs standard, OR 0.52, 95% CI 0.26-1.05; excessive vs standard, OR 1.12, 95% CI 0.58-2.14). CONCLUSIONS: Restrictive resuscitation is associated with increased AKI, without changes in infectious complications.

RESUMO

BACKGROUND: End-of-life (EoL) care after geriatric burns (geri-burns) is understudied. OBJECTIVE: To examine the practices of burn surgeons for initiating EoL discussions and the impact of decisions made on the courses of geri-burn patients who died after injury. METHODS: This retrospective cohort study examined all subjects ≥65 years who died on our Level I burn service from April 1, 2009, to December 31, 2014. Measurements obtained were timing of first EoL discussion (EARLY <24 hours post-admission; LATE ≥24 hours post-admission), decisions made, age, total body surface area burned, and calculated probability of death at admission. RESULTS: The cohort consisted of 57 subjects, of whom 54 had at least one documented EoL care discussion between a burn physician and the patient/surrogate. No differences were seen between groups for the likelihood of an immediate decision for comfort care after the first discussion (p = 0.73) or the mean number of total discussions (p = 0.07). EARLY group subjects (n = 38) had significantly greater magnitudes of injury (p = 0.002), calculated probabilities of death at admission (p ≤ 0.001), shorter times to death (p ≤ 0.001), and fewer trips to the operating theater for burn excision and skin grafting (p ≤ 0.001) than LATE subjects (n = 16). LATE subjects' first discussion occurred at a mean of 9.3 ± 10.0 days. DISCUSSION: The vast majority of geri-burn deaths on our burn service occur after a discussion about EoL care. The timing of these discussions is driven by magnitude of injury, and it does not lead to higher proportions of an immediate decision for comfort care. The presence and timing of EoL discussions bears further study as a quality metric for geri-burn EoL care.

RESUMO

Since the 1940s, the resuscitation of burn patients has evolved with dramatic improvements in mortality. The most significant achievement remains the creation and adoption of formulae to calculate estimated fluid requirements to guide resuscitation. Modalities to attenuate the hypermetabolic phase of injury include pharmacologic agents, early enteral nutrition, and the aggressive approach of early excision of large injuries. Recent investigations into the genomic response to severe burns and the application of computer-based decision support tools will likely guide future resuscitation, with the goal of further reducing mortality and morbidity, and improving functional and quality of life outcomes.

RESUMO

INTRODUCTION: Pediatric burns due to abuse are unfortunately relatively common, accounting for 5.8-8.8% of all cases of abuse annually. Our goal was to evaluate our 36-year experience in the evaluation and management of the victims of abuse in the North Texas area. METHODS: A prospectively maintained database containing records on all admissions from 1974 through 2010 was queried for all patients aged less than 18 years. Patients admitted for management of a non-burn injury were excluded from the analysis. RESULTS: Of 5,553 pediatric burn admissions, 297 (5.3%) were due to abuse. Children with non-accidental injuries tended to be younger (2.1 vs. 5.0 years, p<0.0001) and male (66.0 vs. 56.5%, p=0.0008). Scald was the most common mechanism of injury overall (44.8%), and was also the predominant cause of inflicted burns (89.6 vs. 42.3%, p<0.0001). Multivariate logistic regression identified age, gender, presence of a scald, contact, or chemical burn, and injury to the hands, bilateral feet, buttocks, back, and perineum to be significant predictors of abuse. Victims of abuse were also found to have worse outcomes, including mortality (5.4 vs. 2.3%, p=0.0005). After adjusting for age, mechanism of injury, and burn size, abuse remained a significant predictor of mortality (OR 3.3, 95% CI 1.5-7.2) CONCLUSIONS: Clinicians should approach all burn injuries in young children with a high index of suspicion, but in particular those with scalds, or injuries to the buttocks, perineum, or bilateral feet should provoke suspicion. Burns due to abuse are associated with worse outcomes, including length of stay and mortality.

RESUMO

BACKGROUND: In the patient with burn injury, older age, larger percentage of total body surface area (TBS) burned, and inhalation injury are established risk factors for death, which typically results from multisystem organ failure and sepsis, implicating burn-induced immune dysregulation as a contributory mechanism. We sought to identify early transcriptomic changes in circulating leukocytes underlying increased mortality associated with these three risk factors. METHODS: We performed a retrospective analysis of the Glue Grant database. From 2003 to 2010, 324 adults with 20% or greater TBS burned were prospectively enrolled at five US burn centers, and 112 provided blood samples within 1 week after burn. RNA was extracted from pooled leukocytes for hybridization onto Affymetrix HU133 Plus 2.0 GeneChips. A multivariate regression model was constructed to determine risk factors for mortality. Testing for differential gene association associated with age, burn size, and inhalation injury was based on linear models using a fold change threshold of 1.5 and false discovery rate of 0.05. RESULTS: After adjusting for potential confounders, age greater than 60 years (relative risk [RR], 4.53; 95% confidence interval [CI], 2.93-6.99), burn size greater than 40% TBS (RR, 4.24; 95% CI, 2.61-6.91), and inhalation injury (RR, 2.08; 95% CI, 1.35-3.21) were independently associated with mortality. No genes were differentially expressed in association with age greater than 60 years or inhalation injury. Fifty-one probe sets representing 39 unique genes were differentially expressed in leukocytes from patients with burn size greater than 40% TBS; these genes were associated with platelet activation and degranulation/exocytosis, and gene-set enrichment analysis suggested increased cellular proliferation and down-regulation of proinflammatory cytokines. CONCLUSION: Among adults with large burns, older age, increasing burn size, and inhalation injury have a modest effect on the leukocyte transcriptome in the context of the "genomic storm" induced by a 20% or greater than TBS burned. The 39-gene signature we identified may provide novel targets for the development of therapies to reduce morbidity and mortality associated with burns greater than 40% TBS. LEVEL OF EVIDENCE: Epidemiologic study, level III.

RESUMO

BACKGROUND: Since opening its doors in 1962, the Parkland Burn Center has played an important role in improving the care of burned children through basic and clinical research while also sponsoring community prevention programs. The aim of our study was to retrospectively analyze the characteristics and outcomes of pediatric burns at a single institution over 35 years. STUDY DESIGN: The institutional burn database, which contains data from January 1974 until August 2010, was retrospectively reviewed. Patients older than 18 years of age were excluded. Patient age, cause of burn, total body surface area (TBSA), depth of burn, and patient outcomes were collected. Demographics were compared with regional census data. RESULTS: Over 35 years, 5748 pediatric patients were admitted with a thermal injury. Males comprised roughly two-thirds (66.2%) of admissions. Although the annual admission rate has risen, the incidence of pediatric burn admissions, particularly among Hispanic and African American children has declined. The most common causes of admission were scald (42%), flame (29%), and contact burns (10%). Both the median length of hospitalization and burn size have decreased over time (r(2)=0.75 and 0.62, respectively). Mortality was significantly correlated with inhalation injury, size of burn, and history of abuse. It was negatively correlated with year of admission. CONCLUSIONS: Over 35 years in North Texas, the median burn size and incidence of pediatric burn admissions has decreased. Concomitantly, length of stay and mortality have also decreased.

RESUMO

OBJECTIVE: Characterizing burn sizes that are associated with an increased risk of mortality and morbidity is critical because it would allow identifying patients who might derive the greatest benefit from individualized, experimental, or innovative therapies. Although scores have been established to predict mortality, few data addressing other outcomes exist. The objective of this study was to determine burn sizes that are associated with increased mortality and morbidity after burn. DESIGN AND PATIENTS: Burn patients were prospectively enrolled as part of the multicenter prospective cohort study, Inflammation and the Host Response to Injury Glue Grant, with the following inclusion criteria: 0-99 years old, admission within 96 hours after injury, and more than 20% total body surface area burns requiring at least one surgical intervention. SETTING: Six major burn centers in North America. MEASUREMENTS AND MAIN RESULTS: Burn size cutoff values were determined for mortality, burn wound infection (at least two infections), sepsis (as defined by American Burn Association sepsis criteria), pneumonia, acute respiratory distress syndrome, and multiple organ failure (Denver 2 score>3) for both children (<16 yr) and adults (16-65 yr). Five hundred seventy-three patients were enrolled, of which 226 patients were children. Twenty-three patients were older than 65 years and were excluded from the cutoff analysis. In children, the cutoff burn size for mortality, sepsis, infection, and multiple organ failure was approximately 60% total body surface area burned. In adults, the cutoff for these outcomes was lower, at approximately 40% total body surface area burned. CONCLUSIONS: In the modern burn care setting, adults with over 40% total body surface area burned and children with over 60% total body surface area burned are at high risk for morbidity and mortality, even in highly specialized centers.

RESUMO

The Committee for the Organization and Delivery of Burn Care (ODBC) was charged by President Palmieri and the American Burn Association (ABA) Board of Directors with presenting a plenary session at the 45th Meeting of the ABA in Palm Springs, CA, in 2013. The objective of the plenary session was to inform the membership about the wide range of the activities performed by the ODBC committee. The hope was that this session would encourage active involvement within the ABA as a means to improve the delivery of future burn care. Selected current activities were summarized by key leaders of each project and highlighted in the plenary session. The history of the committee, current projects in disaster management, regionalization, best practice guidelines, federal partnerships, product development, new technologies, electronic medical records, and manpower issues in the burn workforce were summarized. The ODBC committee is a keystone committee of the ABA. It is tasked by the ABA leadership with addressing and leading progress in many areas that constitute current challenges in the delivery of burn care.

RESUMO

Approximately 3415 research articles were published with burns in the title, abstract, and/or keyword in 2013. We have continued to see an increase in this number; the following reviews articles selected from these by the Editor of one of the major journals (Burns) and colleagues that in their opinion are most likely to have effects on burn care treatment and understanding. As we have done before, articles were found and divided into the following topic areas: epidemiology of injury and burn prevention, wound and scar characterization, acute care and critical care, inhalation injury, infection, psychological considerations, pain and itching management, rehabilitation and long-term outcomes, and burn reconstruction. The articles are mentioned briefly with notes from the authors; readers are referred to the full papers for details.
