The elderly population is on the increase globally according to the current global demographic changes and is more vulnerable to burn injuries. Despite recent advances in burn care, the outcome of burns in the elderly has only marginally improved when compared with children and younger adults. The objective of this study was to determine the patterns and outcomes of burns in the elderly and eventually proffer prevention strategies. A retrospective review of all the elderly (65 years and older) burn patients managed at the Burn Centre of National Orthopaedic Hospital Igbobi Lagos (NOHIL) between January 2015 and December 2019 was performed. The socio-demographic data, clinical information surrounding the burn injury and management were extracted from the medical records, analyzed and presented. A total of 21 patients were included in this study, with a male to female ratio of 1:1.1. Flame burns represented the commonest cause of burns (85.7%) and the majority had pre-injury comorbidities (57.1%). All the patients with %TBSA of less than 40% were successfully managed and discharged while death occurred in all the patients with %TBSA of 40% and above, with a mortality rate of 11.1%. This study provided an epidemiological profile of elderly burn patients in Nigeria. One in five burn admissions is elderly, with flame burns being the major cause of burns. Most of the burns occurred indoors and were related to cooking activities. Prevention strategies were recommended to improve home safety and make the home a safer place for the elderly.

Minimally invasive surgery is becoming the standard of care across surgical subspecialties. Several new "minimally invasive" options for burn debridement and autografting exist. Enzymatic bromelain-based debridement (BBD) and autologous skin cell spray (ASCS) have independently proven to reduce the rate of split-thickness skin grafting (STSG) and decrease donor site size when grafting is performed. There is a paucity in the literature regarding the combination of these two therapies. The purpose of this study is to characterize a cohort of patients treated with both BBD and ASCS and qualitatively compare data to expected outcomes without these therapies. This retrospective study of a single academic burn center's experience using BBD and ASCS together included 13 patients with a total burn surface area (TBSA) from 1-30% and all had >50% deep partial thickness. All patients received BBD and ASCS. Deeper burns additionally received STSG with ASCS overspray. Median burn size was 14% TBSA (IQR:5.45,20), donor site size was 225 sq cm (IQR:28.5,556.5), and ratio of donor site area to total treatment area of 0.082 (IQR: 0.039, 0.241) was observed. Median observed length of stay (LOS) was 19 days (IQR:10,27), expected LOS was 15.4 days, and O/E ratio 1.06. Donor sites in both groups of patients were much smaller than expected versus treatment with conventional meshed STSG alone and length of stay is lower than expected based on burn size. An emphasis on expenses and scar development will guide future studies into the patient subset and wound features that are best for this combination treatment.

Burns are a public health concern burdening the healthcare delivery system across the globe. Mortality rates are significant outcome parameters after a burn injury. The objective of the current study was to analyze the characteristics of the patients admitted to our burn care center and identify the factors related to mortality in the burn patients. This was a cross-sectional single-center study involving a retrospective analysis of mortality rates in burn patients over a period of 15 years from July 2007 to December 2021. During the study period, 7,866 burn patients were admitted to the ICU of the burn care center. Patients who died [Group 1] were compared to the group of survivors (control cases [Group 2]) to ascertain the contributing factors that might forecast a high risk for mortality. The mortality rate was calculated as 23.16% (1,822/7,866). The majority of the patients (both groups) had a total body surface area (TBSA) of >50% (p 0.001). The average duration of stay at the burn care center was 15.5 days for the survivors' group (Group 2) while it was 11.4 days for the patients who died (Group 1) during the course of their treatment. About 23.16% of all admitted patients died mostly from flame burns, and sepsis was the commonest cause of death. Patients with risk factors should be classified as high risk for mortality at the time of ICU admission. It is necessary to initiate educational and awareness programs for sensitization related to the prevention of burn injuries.

Despite current workplace protection measures, chemical burn accidents are not uncommon. Among these, alkali burn is the most challenging due to its silent behaviour and aggressive mechanism. Characterized by its initial painless onset, allowing a prolonged exposure, it tends to result in deeper and more destructive burns, creating major reconstructive and therapeutic challenges. This case concerns a 53-year-old male who sustained a full thickness burn of his left instep foot after prolonged contact with an alkali substance. The wound was submitted to several surgical debridement procedures, with preservation of the major tendinous and vascular-nervous structures. The skin defect was then repaired with skin graft. Early recognition and prompt management with copious and prolonged wound irrigation is paramount. As in this type of burn it is difficult to initially assess its true depth, even after initial surgical debridement, a more cautious approach is recommended. Chronic pain is associated with chemical burns and it should be treated early in the process with the use of multimodal analgesia in order to prevent future complications. No matter the absence of major complaints in the 4 week-postoperative evaluation, the possible long-term consequences are still unknown. Despite the prolonged exposure time and the initial presentation with a deep burn, after several surgical debridement procedures, preservation of major tendon and neurovascular structures was assured, which allowed a plain approach for reconstruction of the wound with a skin graft. The case illustrates different challenges associated with evaluation and treatment of patients with deep alkali burns. Also, usage auditing and awareness of regular users appear to be essential.

In contrast to tangential excision, enzymatic debridement with NexoBrid^® selectively removes non-viable tissue, allowing some deep dermal burn wounds to still heal conservatively. In this retrospective study, we investigated the reduction in surgery and associated scarring following enzymatic debridement in definitely deep burns as proven by laser Doppler imaging. One hundred two exclusively laser Doppler imaging-blue regions of interest where there was no doubt at all about the surgical indication, were selected for analysis in 32 patients treated with NexoBrid^®. The total surface area of the 102 exclusively blue regions of interest was 5,086.4cm². NexoBrid^® resulted in a substantial reduction in the need for autografts as 1,986.9cm² (39%) healed with conservative treatment. This corresponded with a significant reduction in patients (56.3%) requiring surgery. Exclusively laser Doppler imaging-blue regions of interest treated surgically with split thickness skin grafts required significantly more time to heal compared to conservative treatment (37.8±17.5 vs. 27.0±10.5 days). A very limited rate of hypertrophic scarring (16.7%) was observed. This is the first paper demonstrating a proven and significant reduction in the extent of autografting as well as in the number of surgical procedures after selective enzymatic debridement in objectively laser Doppler imaging-defined and therefore proven deep burns. Even after extended conservative treatment with prolonged healing times following NexoBrid^®, hypertrophic scar formation was limited (5/54 regions of interest, 9.3%). Also in operated patients, the incidence of hypertrophic scarring following a strict regimen of aftercare was low (12/48 regions of interest, 25%).

The aim of this study was to investigate factors independently affecting outcomes of post-burn ARDS patients at the time of ARDS onset. A prospective study was conducted on 66 patients with ARDS, treated in the ICU at the Le Huu Trac National Burns Hospital in Hanoi, Viet Nam, from 2014 to 2017. Patients were divided into a survivor and non-survivor group. Demographic criteria, burn severity, inhalation injury, clinical and subclinical features at ARDS onset were compared between the two groups. The results showed that overall mortality of ARDS patients was 62.12%. Logistic regression analysis indicated that at the time of ARDS onset, serum lactate level (OR=6.71), blood platelet count (OR=.99), static lung compliance (OR=.73) and driving pressure (OR=1.69) were independent risk factors for death, while patients' demographics, burn severity and ARDS severity did not significantly affect the mortality rate.

Self-immolation is a violent way of committing suicide. Few studies have focused on this phenomenon in children. The aim of this study was to determine the epidemiological profile of children who committed suicide by fire. A retrospective descriptive study was conducted in an intensive burn care department in Tunis, over a period of 10 years (2011-2020). Of a total 3077 patients, 761 were admitted for burns by suicide attempt, among them 62 children and adolescents (8%). The number was on average six per year. The highest annual prevalence was noted in 2011 (27% of cases). The mean age was 16 and a half years old. The majority of cases were adolescents aged 15 or older. There is a male predominance (sex ratio:3). Total burn surface area (TBSA) was on average 44%. The act of self-immolation occurred in public places in 58% of cases. Socio-economic environment was unfavorable in 60% of cases. The suicidal act of self-immolation was due to a family conflict in 34% of cases (n=21). Seven patients (11%) had a history of mental illness. Forty-three patients (70%) required mechanical ventilation. The length of hospital stay was on average 30 days. The mortality rate was 56.5%. In conclusion, self-immolation is frequent in the pediatric population; it induces severe burns associated with a poor prognosis.

This descriptive observational study aims to describe the epidemiological profile of children hospitalized for burns in Guyana, a French district which does not have a burn treatment centre, and direct prevention towards the populations most at risk. Retrospective analysis of 665 hospitalizations was made thanks to the coding of patients aged 0 to 18, hospitalized for burns between January 2010 and December 2022 at Cayenne Hospital Centre. Univariate and multivariate descriptive analyses were carried out on age, sex, municipality of origin, date of burn, duration of hospitalization, mode of burn, location, percentage and depth of burn. A total 416 children with "burn" coding were hospitalized over this period and 358 patients were included. Burns were more common in males (58%) and in children under 6 (75%). A majority of patients were townspeople and lived on the coast (70%). 9.5% of patients were transferred to Trousseau Hospital in Paris for more specialized care. 61% of burns were caused by hot water and 16.5% by flames. Duration of hospitalization was on average 8 days and the burnt skin surface was 9.5%. Children under 2 years old living in Cayenne and its suburbs are the most at risk of burns, but the most serious burns requiring a transfer to Paris are found in children over 3 years old living on the Maroni River and playing with flammable products.

Burn injury is trauma with several metabolic reactions including hepatocytes that can cause apoptosis and necrosis. Proliferation occurs to compensate for this reaction but complicates with the loss of protein of the injury. The aim of this study is to describe the level of aspartate aminotransferase (AST) and alanine aminotransferase (ALT) in burn injury. This study was a descriptive retrospective design using secondary data from medical records of patients at the Burns Unit of Dr. Hasan Sadikin Hospital Bandung (RSHS) in the period August 2017 to July 2019. Total samples in this study were 116 people. Normal level of AST and ALT was found in 23 people (19.8%), elevation of AST in 31 people (26.7%), elevation of ALT in 5 people (4.3%) and elevation of both AST and ALT in 57 people (41.3%). Increased levels of AST and ALT mostly occurred in men (51%), aged 45 years (56%), with injury due to electricity (26%), 20-29% burn area (32%), and occurred in the first week of wound onset. Most cases of burn injury showed increasing levels of AST and ALT. This might be due to the metabolism of hepatocytes in burn cases. Elevation of AST and ALT was mainly found in burn injury cases at RSHS notably in the first week of onset. Further research is needed to verify the relation of this condition. Elevated levels of AST and ALT should be the consideration of clinicians in giving therapy.

Nosocomial infection is a major challenge for the appropriate management of burns. The present study aimed to investigate incidence, risk factors, and causative organisms of nosocomial infection in burn patients of Khulna, Bangladesh. This cross-sectional study was conducted among patients admitted to the Burn and Plastic Surgery Department of Khulna Medical College Hospital (KMCH) from January to December 2020. Relevant data were collected from the patients' hospital records. Samples of wound swabs and blood were collected and cultured in the microbiology laboratory of KMCH. Logistic regression models were used to determine risk factors for infective complications in burn patients. All statistical analyses were carried out using SPSS version 26.0. A total of 100 burn patients were included. Mean age was 29.2 years with a male-female ratio of 1.3:1. Flame burns were most prevalent among the patients (41%), followed by scald (23%) and electric burns (15%). Almost 40% patients had full thickness burn. The incidence of nosocomial infection was 42% (wound infection 33% and septicemia 9%). Total body surface area of burn >40% (OR 7.56, 95% CI 2.89-19.81), full thickness burn (OR 34.40, 95% CI 3.25-97.14) and prolonged hospital stay (aOR 1.31, 95% CI 1.15-1.51) were significant risk factors for nosocomial infection. Staphylococcus aureus was the most commonly isolated organism (45%), followed by Streptococcus (24%), Pseudomonas aeruginosa (19%) and Escherichia coli (12%). As the epidemiology of nosocomial infection is not the same in different health facilities, a facility-based comprehensive burn management protocol considering the local epidemiology and causative organisms of burn wound infection is crucial for the prevention and management of nosocomial infections in burn patients.
