Cell free DNA as a biomarker in medicolegal assessment in burn patients

Background: Burn victims have higher levels of cell free DNA (cfDNA), which allows its use as a direct indicator of cellular damage and burn vitality. Aim: Determination of cfDNA levels in burn patients and their correlation with total body surface area burned percent (TBSA%). Subjects and methods: Burn cases were evaluated to determine the prevalence of age and sex variations, period of admission, TBSA%, and the etiology and manner of burns. The plasma cfDNA concentration was measured within 24 hours of the burn injury in 40 burn cases and 20 control subjects. Results: The mean age of the cases was 34.38 years (median 33 years). Most patients were males (62.5%). Burning by flame or scalding represented 50% of the cases. Accidental burns were the most predominant. The mean of admission periods was 36.55 days while the mean value of TBSA% of the cases was 16.68%. There was a statistically significant difference in cfDNA values between cases and control subjects (p = 0.001). A positive correlation was found between cfDNA levels and TBSA% (r = 0.7; p < 0.001). Conclusion and recommendations: Levels of cfDNA were significantly different between burn cases and controls.

Clinical study and management of burns in adults

Background: Burn injuries are amongst one of the most devastating of all injuries, having a great impact on the patients physically, physiologically and psychologically. Burns are still one of the top causes of death and disability in the world.Aims: To study the etiology of burn, nature of burn and mortality rate in burn patients.Material and Method: A prospective institutional two year observational study of 100 patients of burn injury admitted under department of general surgery at Solapur.Result: Highest number of patients was from 18 to 30 years. The Female to male ratio is 1.77:1. Maximum number of patients has 81-100% burn (31%) with mixed burn in 51%. Accidental burn (79%) was the most common type of burn. Flame burn (74%) was most common. Overall mortality was 55%, recovery in 27% and 18% cases have residual disability.Conclusion: Accidental flame burn commonly affects young females with maximum patients having 81-100% TBSA. Mortality was more than 50%.

Pain assessment and clinical profile of burn patients

Background: Burn injuries are a major global public health concern with up to 52% of burn patients suffering from chronic pain. The aim of the study was to asses clinical profile and management of pain in burn patients.Methods: The study was a prospective hospital-based study on a total of 300 patients admitted in burn unit of the department of surgery over a period of two years. BSA burns was determined by Wallace's rule of nine in adults and in children by Lund and Browder chart. Pain was assessed using Wong-Baker FACES pain rating scale. Statistical analysis was done using SPSS program.Results: In the present study, most of the burns i.e., 46.7% were seen in <20 years age group, and more in male (58.7%) subjects. Accidental burns and superficial burns were the most common. There were 113 (53.3%) patients with pain score of 2 followed by 160 (53.3%) with pain score 3, 22 (7.3%) pain score 4 and 5 (1.7%) with pain score of 1. For pain management, 171 (57%) patients were given NSAIDS, 78 (26%) needed opioid and NSAIDs and 51 (17%) needed opioid only. Complications in our studied patients on follow up revealed 29 (9.7%) had PTSD, 22 (7.3%) had post burn contracture, 16 (5.3%) had post burn pain, 15 (5.0%) were having anxiety.Conclusions: Pain in burn victims is present throughout the rehabilitation and so should be dealt with multimodal specialties.

Clinico-epidemiological study of burn patients admitted in a tertiary care hospital of Solapur, Western Maharashtra

Background: Burn injuries constitute a major public health problem and account for a significant cause of high mortality and morbidity amongst the Indian population. This results in heavy social, economic and clinical burden to the nation. The aim of the study was to evaluate the demographic and clinical profile of burns patients admitted in a tertiary care center and to study the socio-demographic and clinical profile of burn patients and to assess the outcome of burn patients.Methods: Hospital based descriptive study with cross sectional design was done using the records of all burn patients admitted in burn ward of surgery department during 1st January 2019 to December 31st 2019.Results: Burn injuries were most common in the age group of 41-60 years. The male to female ratio was 0.65: 1. Most of the burn incident took place in rural area (73%) and rest (27%) in urban area. Most of the mode of burn injury (88.7%) were accidental burns, 8.2% had alleged history of suicide and in rest 3.1% homicide was suspected. Mortality ratio was 33.30% and 66.70% of patients got discharged from the hospital. A higher TBSA involvement is statistically associated with an increased risk of mortality (p<0.05).Conclusions: The prevention strategies for burns should address the hazards of specific burn injuries, awareness education for vulnerable population and targeted first aid training. The burn units should be established well to reduce the mortality.

815 Translational Research in Skin of Color Spontaneous Repigmentation of Post-Chemical Burn Leucoderma

IntroductionAfter facial burn injuries to skin of color (SOC) patients, repigmentation plays a critical role in post-burn quality of life, given the acquired contrast between preserved skin and achromic scars, and that daily concealment may be difficult. While leucoderma is a well-known side-effect of deep chemabrasion with phenol, phenol-croton oil, and high concentration trichloroacetic acid, mechanisms of repigmentation are still not fully understood, and the observation of spontaneous repigmentation of a deep chemical injury in SOC has not previously been described in the literature. In our study, we present the dynamics of long-term spontaneous facial repigmentation of a Fitzpatrick V chemical burn patient, with microscopic findings of a deep chemical peel SOC animal model.MethodsWe demonstrate spontaneous repigmentation in a 37-year-old female who initially presented with depigmented areas, erosions and eschars on the face, 7 days after accidental deep chemical burn, due to self-application of 70% glycolic acid to improve acne. This is juxtaposed with a SOC porcine experiment, performed with 35% phenol, 1.6% croton-oil, to evaluate depth-of-injury, neocollagenesis band thickness in 21 days, and skin pigmentary safety. A 6mm punch biopsy taken at 21 days underwent Herovici staining to reveal the thickness of collagen type III neocollagenesis, confirm the presence of melanin in the epidermis, and evaluate the presence of melanophages.ResultsOn patient presentation, epidermolysis and areas of deep dermal burns were observed over the forehead and cheeks. At 14 days, multiple leucoderma scars persisted and initial perifollicular repigmentation was noticeable. At 28 days, most of the skin was repigmented; however, many areas had only perifollicular repigmentation and still very severe leucoderma. At 6 months, the skin still had small areas of leucoderma with folicular repigmentation. At 11 months the skin color was fully recovered, with minimal post-inflammatory hyperpigmentation (PIH) over the cheeks.As for the SOC animal model, at 7 days the eschar was detached, and the skin was achromic. At 21 days, skin pigmentation was completely restored without macroscopic signs of PIH. Dermatopathology evaluation revealed microscopic areas of melanophages, a fully recovered epidermal melanin, and a band of over 500 micra of collagen type III.Overall, on follicle-dense areas after chemical burn, we observed progressive full repigmentation over the course of 11 months on the patient, and by day 21 in the porcine SOC model.ConclusionsSpontaneous repigmentation occurred both after accidental deep chemical ablation to the face of a SOC patient, and on the porcine SOC model after deep chemical peel formula application.

National expert consensus on the aeromedical trans- portation of burn patients (2022 version)

The development of burn units in our country is now undergoing a trend of geographic centralization and regionalization. To solve the problems like severe burn patients are too far away from burn units, overloaded operation in regional burn centers when mass burn accidents happen, and growing requirement for aeromedical transportation, etc., it is now the top priority to improve national aeromedical transportation system for burn patients. Expert teams from Chinese Burn Association, National Aeromedical Rescue Base, and China Association for Disaster & Emergency Rescue Medicine discussed and reached a consensus on the key points of aeromedical transportation of burn patients, including organizational structure, staff and materials, and three links before, during, and after aeromedical transportation. The consensus aims to provide guidance for a safe, efficient, and standardized operation of aeromedical transportation for burn patients in China.

Comparison of accidental pediatric scald burns in a tertiary care center: hot cauldron burns versus accidental spill burns

Background: Scald burns result from exposure to high-temperature fluids and are more common in the pediatric age group. They occur mainly by two mechanisms: (i) spill and (ii) immersion (hot cauldron) burns. These two patterns differ in clinical characteristics and outcomes. Scalds cause significant morbidity and mortality in children. The objective of this study was to compare accidental spill burns and hot cauldron burns in a hospital setting. Methods: An analytical cross-sectional study was conducted by reviewing the secondary data of scald cases admitted during the years 2019 and 2020 in a burn-dedicated tertiary care center. Total population sampling was adopted. Data analysis was done partly using SPSS, version-23, and Stata-15. Mann Whitney U-test and Chi-square/Fisher's exact test were done appropriately to find associations between different variables. Binary regression analysis was performed taking mortality events as the outcome of interest. Results: Out of 108 scald cases, 43 (39.8%) had hot cauldron burns and 65 (60.2%) had accidental spill burns. Overall mortality was 16 (14.8%), out of which hot cauldron burns and accidental spill burns comprised 12 (75.0%) and 4 (25.0%), respectively. Binary logistic regression analysis showed the type of scald, age, and Baux score found to be associated with mortality. Every one-year increment in age had a 29% lower odds of occurrence of mortality event (adjusted odds ratio [OR], 0.71; 95% confidence interval [CI], 0.50-0.99, p=0.042). Likewise, every one-point increment in Baux score was associated with 19% higher odds of mortality (adjusted OR, 1.190; 95% CI, 1.08-1.32; p<0.001). Conclusions: Accidental spill burn was more common but mortality was significantly higher for hot cauldron burns. The risk of mortality was significantly higher in burn events occurring outside the house, and burns involving back, buttocks, perineum, and lower extremities.

Changing concept in Burns Management- An Analytical study of Epidemiology, Morbidity, Mortality and Treatment in a period of forty years in the Indian state of Assam

There is an improvement in the morbidity and mortality in burns in the recent past due to better fluid resuscitation, use of better burn wound covers and early excision and skin grafting for full thickness burns. Burn care in the North Eastern Indian state of Assam was disorganized in the eighties, but individual efforts by some surgeons of the state, have improved outcome. This is a retrospective analysis of 8569 cases of burn injuries treated in three hospitals of Assam over a period of 40 years. The study intends to analyze the epidemiological pattern of burn injuries in order to plan preventive strategies and also to compare the results of treatment with and without an organized burn care unit. There were 7071 (82.3%) minor burns and 1518(17.7%) major burns in the series. The period of study was divided into three blocks - Block I- first 14 years of disorganized management, before establishment of Burns Unit, Block II -next 16 years of organized management after establishment of Burns Unit and Block III - last 10 years of advanced care with introduction of newer burn wound covers and early excision of burns. The data were analyzed and compared. The overall incidence of burns was more in males, but a greater number of females were the victims of major burns.77.2% of patients were below 40 years of age. The number of accidental burns remaining constant in the three blocks, there was a significant increase in the suicidal burns in the last two blocks. Flame burns (56.7%) constituted the majority of injuries, while scald (31.3%) and electrical burns (9.3%) followed. Domestic burns (73.1%) were of most common occurrence, followed by Industrial (10.8%), Diwali related (9.6%) and Traffic burns (6.4%). Though the overall mortality in the three blocks were almost same (Block I- 9.4%, Block II- 7.8% Block III-9.4%), mortality in major burns were reduced significantly after introduction of modern methods of management (Block I- 79.7%, Block II-52.0% Block III-38.4%). The quality of wound healing showed improvement in the subsequent years as evident by increase in number of patients with no scar (Block I -10%. Block II-20%, Block III- 37%) and decrease in number of patients with extensive scar (BlockI-18%, Block II- 15%, Block III-5%), measured by Vancouver Scar Scale. This analytical study has given us an understanding of the magnitude of the problem of burns in the region, which will help to plan treatment and preventive strategies. It also concludes that, dedicated individual care and introduction of newer methods of treatment have improved results of burn management. Key words: Epidemiology, treatment, morbidity and mortality

Prayer burns

Introduction: In Indian culture, it is considered auspicious to conduct prayers before beginning one's day or even before starting to celebrate any of the festivals. The variations in conducting the prayers are numerous, but one thing which is constant is fire, which in the form of diya or candle or incense stick is always present. This many a times becomes the source of clothes catching fire leading to burns. The flame burns can cause serious complications depending on the age and the percentage of the body involved. Herein, we are presenting an article regarding the same. Methods: All burns which occurred while praying from September 2019 to September 2021 were included in the case series. Results: In our study, the patients above 60 all had comorbid conditions, and 5 out of 8 (five out of eight) patients expired that is 62.5% of the study group. These patients had the accident at home while praying where the flame from diya which is lit on the temple floor near the idol of god caught fire to the clothes. Indian females prefer to wear clothes with flairs such as chaniya choli, long Indian skirt, or saree which increases the chances of contact with diyas or source of flame leading to accidental burns. Considering that 5 (five) patients were more than 50 years of age, they survived for mean days of 16.2 days and then expired, the three younger patients recovered with an average stay of 47.3 days. Even with extensive burns due to younger age the patients recovered and did require skin grafting in the course of their treatment. Discussion: Diminished alertness of the senses, impaired mentation, slower reaction time, reduced mobility, and decreased ability of elderly people to identify the severity or risk of a situation as well as their capacity to escape from harm, puts them at higher risk of sustaining burn injury. These circumstances will also lead to larger increased total body surface area (TBSA) and deeper burns; moreover, there is an increased risk for the development of inhalation injury. These factors are closely related to a higher mortality rate. Conclusion: Age plays an important role in treatment response in a major trauma like burns. Increased age with associated co morbidities add to the severity of the burns. Younger age group however have better survival chances, though even they required prolonged hospital stay in our study considering the higher percentage of burns involved.

Epidemiological and Clinical Characteristics of Burn Injuries among Hospitalized Patients in Babylon Province

Background: Burns form the fourth most common cause of injury after road traffic injuries, falls, and interpersonal conflicts and are usually correlated with devastating physical, mental, social, and financial harms, particularly in low and middle-income countries like Iraq. Objectives: To investigate the epidemiological and clinical characteristics of burn injury patients, to measure the mortality rate (case fatality rate) for burns, and to explain the main determinants of deaths among hospitalized burn injury patients. Patients and Methods: This was an observational descriptive cross-sectional study conducted on all acute burn injury cases who were admitted to the biggest teaching hospital in Babylon Province, Iraq. Data were collected from patients themselves or their companions and from patients’ hospital records using a pretested questionnaire designed for collecting the requested information that included demographic data, burn characteristics, burn determinants, and burn outcomes. Results: A sample of 120 patients with burn injuries were investigated. The mean age ± standard deviation was 18.9 ± 17.9 years. The mean age of burn death victims was 24.5 ± 17.66 years. The young age group (15–24 years) represented the highest proportion. Male to female ratio was 1:1.4. Most of the patients had low educational and income levels. The case fatality rate was 26.6% (32/120). The majority of cases were from rural areas; 67% of suicidal burn deaths had more than 50% of total body surface area. Intentional burn death victims had significantly severe burns (third-degree burn and high body surface area) as compared to accidental burn death victims. There was a statistically significant difference as regards the mode of burns between the intentional and accidental burn deaths; all intentional death victims were burnt with flame. Conclusions: The case fatality rate of burn injuries was high, females outnumbered males, the majority of the victims had low educational and income levels, and suicidal burn deaths were significantly associated with severe burn as compared to the accidental ones.

Tilapia skin and its applicability in the treatment of burns

Burn accidents present a relevant frequency in Brazil and worldwide, maintaining high morbidity and mortality rates. Burn care requires long treatment, numerous consultations, dressing changes and long hospital stays, generating high costs for the health system. The objective of this study is to propagate the theme to increase the understanding of the recent biological dressing with the use of tilapia skin and its applicability in the treatment of burns. The innovative method created in Brazil, has as principle the use of tilapia skin for dressing on burns, with eminent potential in medicine for the treatment of these wounds, where the technique with “biological dressing” has been used since 2016. 19 contributed to a significant increase in burns due to the use of alcohol, both liquid and gel, in the home environment and many accidents with child burns.

The research demonstrated that the biological dressing with tilapia skin is an innovative method in the treatment of burns, being a high quality bioproduct, showing biological capacity to cover burns, collagen properties, tensiometric strength and a biomaterial potential in regenerative medicine.

농산물 가공사업장 발생 안전사고 사례에 대한 근본 원인 분석

Objective: The purpose of this study was to investigate the cases of safety accident that occurred in Agricultural Product Processing Plants (APPPs), and the root cause and system of safety were analyzed by using logic tree diagraming method.<BR>Background: Local rural development organizations have been expanding agricultural processing-related facilities by supporting related education and starts-ups in order to increase non-agricultural income and create jobs. However, since the machinery and equipment of agricultural processing plants use high-pressure, high-temperature, and high-speed rotation, workers are exposed to various risks. Since the number of safety accidents occurring at APPPs is increasing every year, it is necessary to manage and control the characteristics of accidents.<BR>Method: The cases of 29 safety accidents that occurred in 10 APPPs were collected. Demographic characteristics and risk factors were investigated for 29 people who experienced accidents. In addition, logic tree diagraming method was conducted in order to analyze root causes and systems of safety.<BR>Results: For the rate of 29 accidents by type of accident risk, high-temperature (41.4%) was identified as the highest rate, followed by excessive force/movement (20.7%), bump (13.8%), and jammed (6.9%). As for the type of injury, burns (48.3%) had the highest rate, followed by musculoskeletal disorders (20.7%), incised wound (10.3%), and cut (6.9%). Fracture, amputations, and stabbed were 3.4%, respectively. As results of logic tree diagraming method, 119 root causes were derived, which were classified into six categories in systems of safety. The most common system of safety was mitigation (28.6%), followed by design (23.5%), personal protective equipment (19.3%), training (17.6%), warning (9.2%), and communication (1.7%).<BR>Conclusion: It was confirmed that the accident types in APPPs were similar to those in general industries, and it was determined that control and management of burn accidents were necessary. In addition, it is considered that measures such as installing protective devices, attaching warning signs, and wearing appropriate personal protective equipment are necessary to minimize the risk of APPPs.<BR>Application: It is hoped that the results of this study will be utilized in the development of safety guidelines, checklist items, and manuals for the prevention of safety accidents for workers in APPPs.

AMELOGLYPHICS-AN UPDATED REVIEW

In this modern era equipped with technologies, the crime rates are increasing exponentially. This requires newer methodologies to identify a person who is a victim as well as the perpetruator. Automated biometric systems helps in identifying the individuals by the stored information in the database which are unique for each individual. Some of the important methods are ngerprint biometrics and iris scanning.As these methods involves soft tissues they cant be relied upon during mass disasters like burn accidents and gas leakage accidents. Hence, a biometric system using the hard tissue is required for better identication of the individuals. Thus, Ameloglyphics is introduced to aid in identication of individuals died during mass disasters and it plays a vital role in forensic odontology. This review highlights this technology in detail.

Long term effects of burn injury on health-related quality of life of adult burn survivors in Iceland: a descriptive cross-sectional study and validation of the Icelandic version of the Burn Specific Health Scale-Brief (BSHS-B)

The aim of the study was to assess the long-term effects of burn injury on the health-related quality of life of adult burn survivors in Iceland and to validate the translated Icelandic version of the Burn Specific Health Scale-Brief (BSHS-B). The participants of this descriptive cross-sectional study were all burn survivors, 18 years or older, admitted to hospital for 24 hours or more because of skin burn during a 15 years period (N=196). They completed questionnaire about their health (BSHS-B), health related quality of life (EQ-5D-5) and additional questions on burn-related symptoms and their burn experience. Response rate was 34% (N=66). Men were 77%, mean age 45.7 years (sf=18.3 and range 18-82 years), mean age when burned was 34.0 (sf=20,1, range 1-75), median time from burn accident was 11.5 years (range 1-44 years) and 32% had been burned when under 18 years of age. Burn-specific health was 4.4-4.0 (median) and health on the EQ5D-5vas scale was 80 (median, range 10-100). Those who lost a body part or had skin transplantation had more negative body image and needed more selfcare than others (p<). A significant proportion of participants reported physical and psychosocial symptoms such as itch (48%), persistent pain (37%), anxiety/depression (29%) and negative self-image (37%). Majority (67%) believed they did not get enough information, follow-up, or support after discharge from hospital. The Icelandic version of the Burn Specific Health Scale-Brief (BSHS-B) was reliable, but more research is needed to establish its validity. These findings suggest that most Icelandic burn survivors report acceptable health and health-related quality of life. The study identified a subgroup of survivors that experience persistent physical and psychosocial symptoms. Team approach with holistic support after discharge, for a prolonged period of time aiming at preventing physical and psychiatric morbidity, is recommended.

Study on Improving the Levitation Force for a Maglev Load Reduction Machine

The tiles burning accident may happen with the temperature rising because of the severe friction if the axial load was very big for the thrust bearing. We proposes using maglev technology to reduce the load for the thrust bearing to avoid the accident. Based on the principle of not coupling the original system, a disc electrodynamic maglev machine is designed, which will provides a normal repulsion as the levitation force to offset one part of the axial load for the bearing with the advantages of good self-stability and light secondary. The tangential force generated at the same time and is useless. The electrical and structural parameters both affect two forces. This paper studied the analytical calculation method, the relationship of the two forces, and the energies stored in the air-gap and expended in the secondary. Then the laws of parameters affecting the forces are obtained, which reveal the design method to improve the levitation force and decrease the tangential force. Based on the theoretical research, the Coreless superconductor primary armature is thought most suitable for this machine with higher y-axis component of magnetic field in air-gap. The FEA simulation model is used to verify the theoretical analysis.

Impact of PM2.5 concentration, weather and population on COVID-19 morbidity and mortality in Baghdad and Kuwait cities.

The coronavirus (COVID-19) pandemic is a global health crisis and biggest challenge facing the world. Station measurements of fine particulate matter (PM2.5) concentration in Baghdad and Kuwait during the period January–July 2020 are analyzed as well as assessment of correlation between PM2.5, weather conditions (air temperature, relative humidity, wind speed), population density and COVID-19 morbidity and mortality. A significant improvement (decrease) has observed during total and partial curfew in PM2.5 at Baghdad by 35%, 12.4%, respectively, from PM2.5 mean during the study period that is less than the WHO recommended PM2.5 level especially in total curfew. This decrease in PM2.5 pollution and people’s mobility in Baghdad at total and partial curfew contributed to decrease injuries and mortality. PM2.5 during total and partial curfew in Kuwait country witnessed increasing by 38.4% and decreasing by 22.3% from the PM2.5 mean, respectively, but still higher than WHO standard level. This increase in PM2.5 at total curfew was related to burning accidents in the oil wells which caused increasing in PM2.5 pollutant and then an increase in number of injuries and mortality during that time. In general during all study period our research found that PM2.5 and wind speed exhibit weak relation with COVID-19 morbidity and mortality but strong relation with increasing temperature and decreasing humidity. The high population density had a good association with increasing daily new cases, mortality due to COVID-19 pandemic. Thus, these factors may be taken into consideration in policy development for the control and prevention of new chains of the Coronavirus pandemic.
