    J Forensic Leg Med, 2007 Jan;14(1):3-6.
    PMID: 17046310
    The purpose of this study was to record and evaluate the causes and the magnitude of the fatal burn injuries retrospectively. An analysis of autopsy records revealed 19.4% cases of burn injuries amongst the total autopsies done over 10years period (1993-2002) in the mortuary of the department of Forensic Medicine of Kasturba medical College, Manipal. The majority of deaths (78.5%) occurred between 11 and 40years of age group with preponderance of females (74.8%). The flame burns were seen in 94.1% of the victims followed by scalds and electrical burns in 2.8% and 2.5% cases, respectively. The majority of burn incidents were accidental (75.8%) in nature followed by suicidal (11.5%) and homicidal (3.1%) deaths. The percentage of burn (TBSA) over 40% were observed in most of the cases (92.5%). The majority of deaths occurred within a week (69.87%) and most the victims died because of septicemia (50.9%).

    Skin is the largest organ in human system and plays a vital role as a barrier against environment and pathogens. Skin regeneration is important in tissue engineering especially in cases of chronic wounds. With the tissue engineering technology, these skins equivalent have been use clinically to repair burns and wounds. Consented redundant skin samples were obtained from patients aged 9 to 65 years old. Skin samples were digested with dispase, thus separating the epidermis and the dermis layer. The epidermis layer was trypsinized and cultured in DKSFM in 6-well plate at 37 degrees C and 5% CO2. Once confluent, the culture were trypsinized and the cells were pooled. Cells were counted using haemacytometer. Doubling time and viability were calculated and analysed. From the result, we conclude that doubling time and viability of in vitro keratinocytes cultured in DKSFM media is not age dependant.

    The lower limit of soluble zinc content that can possibly be applied onto a wounded skin as a healing promoter was not known. This study examined skin wound healing process of rats inflicted by partial thickness thermal burn wound as a function of applied soluble zinc contents (0.1 ml of zinc chloride solution 0.01% (w/w) or 5.0% (w/w)). The size, surface morphology and histological profiles of wound beds of untreated rats and those treated with zinc chloride solutions were characterized. A soluble zinc content as low as 10.5 μg/cm2 of skin negated skin wound healing when compared to the untreated rats. This was alarming as the commercial products currently in the market are formulated with a high level of zinc content. Albeit the zinc salt employed was water-insoluble, a minute fraction of soluble zinc might be available to the treatment sites. This could be partially responsible for the late adverse effects such as pruritis and inflammation reported with calamine/diphenhydramine lotion, medicated shampoo, Olay Complete defense moisturizing lotion and Zineryt® topical solution. The skin irritation was likely a resultant oxidative stress action of soluble zinc, where a small fraction could be adequate to negate the skin homeostasis.[Figure: see text]Key messagesZinc is essentially a cofactor for skin collagen formation.Soluble zinc content as low as 10.5 μg/cm2 of skin irritates skin and negates burn wound healing.Skin irritation of commercial products relates to minute soluble zinc content availability.

    Fire is one of the major issues facing Southeast Asian peatlands causing socio-economic, human health and climate crises. Many of these fires in the region are associated with land clearing or management practices for oil palm plantations. Here we study the direct post-fire impacts of slash-and-burn oil palm agriculture on greenhouse gas emissions, peat physico-chemical properties and nutrient concentrations. Greenhouse gas (GHG) emissions were measured using Los Gatos ultraportable greenhouse gas analyser one month after a fire in dry season and five months after the fire event, in wet season. Surface soil samples were collected from each individual GHG measurement points, along with 50 cm cores from both burnt and non-burnt control areas for lab analyses. As an immediate post-fire impact, carbon dioxide (CO2) and methane (CH4) emissions, pH, electrical conductivity, and all macronutrient concentrations except nitrogen (N) were increased multi-fold, while the redox potential, carbon (C) and N content were greatly reduced in the burnt region. While some of the properties such as CO2 emissions, and electrical conductivity reverted to normal after five months, other properties such as CH4 emissions, pH and nutrient concentrations remained high in the burnt region. This study also found very high loss of surface peat C content in the burnt region post fire, which is irreversible. The results also show that surface peat layers up to 20 cm depth were affected the most by slash-and-burn activity in oil palm agriculture, however the intensity of fire can vary widely between different oil palm management and needs further research to fully understand the long term and regional impacts of such slash-and-burn activity in tropical peatlands.

    MyJurnal
    Introduction: Systemic inflammation is the major clinical problem which is constellation of communicable and non-communicable infection equipped with acute to chronic inflammation. It may lead to unfavourable conditions for instance, systemic inflammatory syndrome, burns and sepsis. Systemic inflammation might rotate the steering towards vital clinical maladies including cardiomyopathy, neuroinflammation, hepatitis, liver and kidney diseases and even diabetes. In order to elucidate the molecular insights in these clinical implications, there is an intensive need
    to design rodent model of systemic inflammation having close association with systemic inflammatory conditions in humans. Methods: Presently, lipopolysaccharide (LPS) induced systemic inflammatory rodent model is widely established, reproducible and acceptable among scientists. In this model animals are treated with intraperitoneal injection of LPS ranging from 1-10 mg/kg which leads to instant release of proinflammatory cytokines to provide robust model of systemic inflammation in order to elucidate pathological conditions and their in-depth mechanism to uncover the new anti-inflammatory therapeutic targets. Conclusion: Robust model would open new window to explore anti-inflammatory activities of phytochemicals, small molecules and drug candidates along with crosstalk of different signaling pathways at molecular level.

    Data Brief, 2021 Jun;36:107124.
    PMID: 34095374 DOI: 10.1016/j.dib.2021.107124
    Transboundary emissions of smoke-haze from land and forest fires have recurred annually during the dry period (June to October, over the past few decades) in South East Asia. Hazardous air quality has been recorded in Malaysia during these episodes. Agricultural practices such as slash-and-burn of biomass and peat fires particularly in Sumatera and Kalimantan, Indonesia, have been implicated as the major causes of the haze. Past findings have shown that a diversity of microbes can thrive in air including in smoke-haze polluted air. In this study, metagenomic data were generated to reveal the diversity of microorganisms in air during days with and without haze. Air samples were collected during non-haze (2013A01) and two haze (2013A04 and 2013A05) periods in the month of June 2013. DNA was extracted from the samples, subjected to Multiple Displacement Amplification and whole genome sequencing (Next Generation Sequencing) using the HiSeq 2000 Platform. Extensive bio-informatic analyses of the raw sequence data then followed. Raw reads from these six air samples were deposited in the NCBI SRA databases under Bioproject PRJNA662021 with accession numbers SRX9087478, SRX9087479 and SRX9087480.

  7. Fulltext Iatrogenic Mucosal Burn : A Case Report
    Musa, S., Awang, H.
    Ann Dent, 1996;3(1):-.
    MyJurnal
    A case of mucosal burn during the placement of fissure sealant on the first permanent molars of a 9-year-old Malay boy is presented. The erythematous lesion with accompanying burning sensation appeared a few minutes after the etching liquid, containing 37% by weight phosphoric acid, had accidentally come into contact with the buccal mucosa on the right side of the angle of the mouth. The mucosa showed complete healing after one week. The use of rubber dam for tooth isolation while doing fissure sealant is essential to avoid accidental contact of potentially caustic chemicals, such as the phosphoric acid etchant, with the oral mucosa as it can result in mucosal burns.

    The Southeast Asian (SEA) region is no stranger to forest fires - the region has been suffering from severe air pollution (known locally as 'haze') as a result of these fires, for decades. The fires in SEA region are caused by a combination of natural (the El Niño weather pattern) and manmade (slash-and-burn and land clearing for plantations) factors. These fires cause the emissions of toxic aerosols and pollutants that can affect millions of people in the region. Thus, this study aims to identify the impact of the SEA haze on the Southern region of the Malaysian Peninsula and Borneo region of East Malaysia using the entire air quality observation data at surface level in 2015. Overall, the concentration of PM10 was about two-fold higher during the haze period compared to non-haze period. The concentrations of CO, flux of CO and flux of BC were aligned with PM10 during the entire observation period. The wind field and cluster of trajectory indicated that the Southern Malaysian Peninsula and Borneo were influenced mainly from the wildfires and the combustion of peat soil in the Indonesian Borneo. This study finds that wildfires from Borneo impacted the Southern Malaysian Borneo more seriously than that from Sumatra region.

    Evid Based Complement Alternat Med, 2016;2016:4685246.
    PMID: 27528881 DOI: 10.1155/2016/4685246
    Elephantopus scaber and Clinacanthus nutans are traditionally used as wound healing herb. The objective of the present study is to develop a new polyherbal formulation, by comparison, the herbal combination of Elephantopus scaber and Clinacanthus nutans as an in vitro antioxidant activity with their individual herbal activity followed by fractionation of polyherbal formulation for in vivo wound healing activities and identification of bioactive compounds from their active fractions. Antioxidant activity was performed in vitro by DPPH scavenging antioxidant activity followed by in vivo wound healing activities using excision wound model, incision wound model, and burn wound model. Toxicity of the fractions of the polyherbal formulation was performed by a dermal toxicity test. The result showed that Elephantopus scaber crude extract on the basis of EC50 performs a much faster action (15.67 μg/mL) but with less % inhibition (87.66%) as compared to the combination of the new polyherbal formulation of crude extract (30 μg/mL). The polyherbal formulation has the highest % inhibition (89.49%) at the same dose as compared to Elephantopus scaber (87.66%). In comparison among all crude and fractions of new polyherbal formulation, it was found that the ethyl acetate fraction of polyherbal formulation has the fastest activity (EC50 14.83 μg/mL) with % inhibition (89.28%). Furthermore, during evaluation of wound contraction on excision and incision wound model, ethyl acetate fraction possesses the highest activity with (P < 0.001) and (P < 0.0001), respectively. During burn wound model, aqueous fraction (P < 0.001) possesses the highest activity followed by an ethyl acetate fraction (P < 0.0001). LC-MS analysis discovered the presence of several flavonoid-based compounds that work synergistically with sesquiterpene lactone and other bioactive compounds. In conclusion, flavonoid increases the antioxidant activity that surges the rate of wound contraction and works synergistically with other bioactive compounds.

  12. Fulltext Gelam (Melaleuca spp.) Honey-Based Hydrogel as Burn Wound Dressing
    Mohd Zohdi R, Abu Bakar Zakaria Z, Yusof N, Mohamed Mustapha N, Abdullah MN
    Evid Based Complement Alternat Med, 2012;2012:843025.
    PMID: 21941590 DOI: 10.1155/2012/843025
    A novel cross-linked honey hydrogel dressing was developed by incorporating Malaysian honey into hydrogel dressing formulation, cross-linked and sterilized using electron beam irradiation (25 kGy). In this study, the physical properties of the prepared honey hydrogel and its wound healing efficacy on deep partial thickness burn wounds in rats were assessed. Skin samples were taken at 7, 14, 21, and 28 days after burn for histopathological and molecular evaluations. Application of honey hydrogel dressings significantly enhanced (P < 0.05) wound closure and accelerated the rate of re-epithelialization as compared to control hydrogel and OpSite film dressing. A significant decrease in inflammatory response was observed in honey hydrogel treated wounds as early as 7 days after burn (P < 0.05). Semiquantitative analysis using RT-PCR revealed that treatment with honey hydrogel significantly (P < 0.05) suppressed the expression of proinflammatory cytokines (IL-1α, IL-1β, and IL-6). The present study substantiates the potential efficacy of honey hydrogel dressings in accelerating burn wound healing.

    Malays J Med Sci, 2013 Jan;20(1):88-91.
    PMID: 23613660
    A hot water burn is a thermal injury that results in cell death. Thermal eye injury triggers inflammatory processes, including inflammatory cell influx and/or the activation of various inflammatory cells, which result in the rapid accumulation of extravascular fluid in the ocular tissue. The ocular effect depends on the temperature of the water, and the final visual outcome depends on the severity of the damage to the intraocular structures. We report a 23-year-old woman who experienced a facial hot water burn that resulted in blindness. The patient presented late to the hospital after the unsuccessful use of traditional medication. Facial burns are a known cause of blindness. Public health education on prompt hospital presentation, and resistance to the use of potentially harmful traditional medicine in facial burns is suggested.

    PMID: 19024968
    A major factor limiting survival following extensive thermal injury is insufficient availability of donor sites to provide enough skin for the required grafting procedures. Limitation of autologous grafting promotes the usage of allograft skin substitutes to promote wound healing. Here, we investigated the wound healing potential of allograft single layered tissue engineered skin which comprises of either keratinocytes (SLTES-K) or fibroblast (SLTES-F) with fibrin as the delivery system. Results from gross and microscopic evaluation showed our single layered tissue engineered skin constructed with keratinocytes or fibroblast after gamma radiation with the dosage of 2Gy could serve as allograft for the treatment of skin loss.

    Natural polymer-based hydrogels are of interest to health care professionals as wound dressings owing to their ability to absorb exudates and provide hydration for healing. The aims of this study were to develop and characterize bacterial cellulose/acrylic acid (BC/AA) hydrogels synthesized by electron beam irradiation and investigate its wound healing potential in an animal model. The BC/AA hydrogels were characterized by SEM, tensile strength, water absorptivity, and water vapor transmission rate (WVTR). The cytotoxicity of the hydrogels was investigated in L929 cells. Skin irritation and wound healing properties were evaluated in Sprague-Dawley rats. BC/AA hydrogels had a macroporous network structure, high swelling ratio (4000-6000% at 24h), and high WVTR (2175-2280 g/m(2)/day). The hydrogels were non-toxic in the cell viability assay. In vivo experiments indicated that hydrogels promoted faster wound-healing, enhanced epithelialization, and accelerated fibroblast proliferation compared to that in the control group. These results suggest that BC/AA hydrogels are promising materials for burn dressings.

    PMID: 34055118 DOI: 10.1155/2021/5512755
    This study aims to examine the association of orofacial pain and oral health status and oral health behaviours in facial burn patients. The participants in this cross-sectional study were randomly recruited from the Burn Care Center, Institute of Medical Sciences, Islamabad, Pakistan. An intraoral evaluation was carried out to record the DMFT and OHI-S. A self-administered questionnaire was used to collect information on sociodemographic status, brushing frequency, and dental visits. Orofacial pain during mandibular movement was assessed using the Visual Analogue Scale (VAS). Psychological status was assessed using the Generalized Anxiety Disorder Scale and Impact of Events Scale. ANOVA and simple and multiple linear regression tests were used to analyse the data. From the 90 facial burn patients included, the majority were below 34 years of age, female, single or divorced, and unemployed. The mean DMFT was 10.7, and 71% had poor oral hygiene. 56% of the participants had moderate-to-severe anxiety, and 68% had posttraumatic stress disorder. 53% of the participants had moderate-to-severe pain during mouth opening or moving the mandible with a mean score of 41.5. Analyses showed that orofacial pain was associated with less frequent brushing, irregular dental visits, greater DMFT score, and more plaque accumulation (OHI-S). It was also associated with employment status, the severity of a burn, anxiety, and stress. The treatment and management of dental and oral conditions in burn patients need judicious balance in controlling and accurate assessment of the pain and improving psychological problems in burn patients.

    Burns are a devastating public health problem that result in 10 million disability-adjusted life-years lost in low- and middle-income countries. Adequate first aid for burn injuries reduces morbidity and mortality. The rate of proper first aid practices in other countries is 12% to 22%.1,2 A 5-year retrospective audit was performed on the database of the Burn Unit in Hospital Universiti Sains Malaysia for 2012-2016; this involved 485 patients from the east coast of Malaysia. The mean age of the patients is 17.3 years old. The audit on first aid practices for burn injury showed poor practice. Out of 485 burned patients, 261 patients (53.8%) claimed that they practiced first aid. However, only 24 out of 485 patients (5%) practiced the correct first aid technique where they run their burn wound under cool water for more than 20 minutes. Two hundred and twenty-two patients had not received any first aid. Two patients did not respond to the question on the first aid usage after burn injury. The mean age of patients who practiced first aid was 15.6 years old. Out of the 261 patients who practiced first aid, 167 (64%) run their wound under tap water for different durations. Others practiced traditional remedies such as the application of "Minyak Gamat" (6.5%), soy sauce (5.5%), other ointments (3.6%), milk (1.8%), and eggs (0.7%), as well as honey, butter, and cooking oil (0.4% each). First aid practices for burn injuries in the population of east coast Malaysia are still inadequate. The knowledge and awareness of school children and the general Malaysian population must be enhanced.

  20. Fulltext Predictors of mortality and validation of burn mortality prognostic scores in a Malaysian burns intensive care unit
    Lip HTC, Idris MAM, Imran FH, Azmah TN, Huei TJ, Thomas M
    BMC Emerg Med, 2019 11 07;19(1):66.
    PMID: 31699024 DOI: 10.1186/s12873-019-0284-8
    BACKGROUND: Majority burn mortality prognostic scores were developed and validated in western populations. The primary objective of this study was to evaluate and identify possible risk factors which may be used to predict burns mortality in a local Malaysian burns intensive care unit. The secondary objective was to validate the five well known burn prognostic scores (Baux score, Abbreviated Burn Severity Index (ABSI) score, Ryan score, Belgium Outcome Burn Injury (BOBI) score and revised Baux score) to predict burn mortality prediction.

    METHODS: Patients that were treated at the Hospital Sultan Ismail's Burns Intensive Care (BICU) unit for acute burn injuries between 1 January 2010 to 31 December 2017 were included. Risk factors to predict in-patient burn mortality were gender, age, mechanism of injury, total body surface area burn (TBSA), inhalational injury, mechanical ventilation, presence of tracheotomy, time from of burn injury to BICU admission and initial centre of first emergency treatment was administered. These variables were analysed using univariate and multivariate analysis for the outcomes of death. All patients were scored retrospectively using the five-burn mortality prognostic scores. Predictive ability for burn mortality was analysed using the area under receiver operating curve (AUROC).

    RESULTS: A total of 525 patients (372 males and 153 females) with mean age of 34.5 ± 14.6 years were included. There were 463 survivors and 62 deaths (11.8% mortality rate). The outcome of the primary objective showed that amongst the burn mortality risk factors that remained after multivariate analysis were older age (p = 0.004), wider TBSA burn (p
