Mix of shell material into ICF capsule fuel can degrade implosion performance through a number of mechanisms. One way is by dilution of the fusion fuel, which affects performance by an amount that is dependent on the degree of mix at the atomic level. Experiments are underway to quantify the mix of shell material into fuel using directly driven capsules on the National Ignition Facility. Deuterated plastic shells will be utilized with tritium fill so that the production of DT neutrons is indicative of mix at the atomic level. Neutron imaging will locate the burn region and spectroscopic imaging of the doped layers will reveal the location, temperature, and density of the shell material. Correlation of the two will be used to determine the degree of atomic mixing of the shell into the fuel and will be compared to models. This talk will review progress toward the development of an experimental platform to measure burn in the presence of measured mix. This work is supported by US DOE/NNSA, performed at LANL, operated by LANS LLC under contract DE-AC52-06NA25396.

An Experimental Study of Upward Burning Over Long Solid Fuels: Facility Development and Comparison

NASA Technical Reports Server (NTRS)

Kleinhenz, Julie; Yuan, Zeng-Guang

2011-01-01

As NASA's mission evolves, new spacecraft and habitat environments necessitate expanded study of materials flammability. Most of the upward burning tests to date, including the NASA standard material screening method NASA-STD-6001, have been conducted in small chambers where the flame often terminates before a steady state flame is established. In real environments, the same limitations may not be present. The use of long fuel samples would allow the flames to proceed in an unhindered manner. In order to explore sample size and chamber size effects, two large chambers were developed at NASA GRC under the Flame Prevention, Detection and Suppression (FPDS) project. The first was an existing vacuum facility, VF-13, located at NASA John Glenn Research Center. This 6350 liter chamber could accommodate fuels sample lengths up to 2 m. However, operational costs and restricted accessibility limited the test program, so a second laboratory scale facility was developed in parallel. By stacking additional two chambers on top of an existing combustion chamber facility, this 81 liter Stacked-chamber facility could accommodate a 1.5 m sample length. The larger volume, more ideal environment of VF-13 was used to obtain baseline data for comparison with the stacked chamber facility. In this way, the stacked chamber facility was intended for long term testing, with VF-13 as the proving ground. Four different solid fuels (adding machine paper, poster paper, PMMA plates, and Nomex fabric) were tested with fuel sample lengths up to 2 m. For thin samples (papers) with widths up to 5 cm, the flame reached a steady state length, which demonstrates that flame length may be stabilized even when the edge effects are reduced. For the thick PMMA plates, flames reached lengths up to 70 cm but were highly energetic and restricted by oxygen depletion. Tests with the Nomex fabric confirmed that the cyclic flame phenomena, observed in small facility tests, continued over longer sample. New

Fenofibrate Does Not Affect Burn-Induced Hepatic Endoplasmic Reticulum Stress

Hiyama, Yaeko; Marshall, Alexandra H.; Kraft, Robert; Arno, Anna; Jeschke, Marc G.

2013-01-01

Background Burn injury causes major metabolic derangements such as hypermetabolism, hyperlipidemia, and insulin resistance and is associated with liver damage, hepatomegaly, and hepatic endoplasmic reticulum (ER) stress. Although the physiological consequences of such derangements have been delineated, the underlying molecular mechanisms remain unknown. Previously, it was shown that fenofibrate improves patient outcome by attenuating post-burn stress responses. Methods Fenofibrate, a peroxisome proliferator-activated receptor (PPAR)-α agonist, regulates liver lipid metabolism and has been used to treat hypertriglyceridemia and hypercholesterolemia for many years. The aim of the present study is to determine the effects of fenofibrate on burn-induced hepatic morphologic and metabolic changes. We randomized rats to sham, burn injury, and burn injury plus fenofibrate. Animals were sacrificed and livers were assessed at 24 or 48 hours post-burn. Results Burn injury decreased albumin and increased alanine transaminase (p = 0.1 vs. sham), indicating liver injury. Fenofibrate administration did not restore albumin or decrease alanine transaminase. In addition, ER stress was significantly increased after burn injury both with and without fenofibrate (p < 0.05 vs. sham). Burn injury increased fatty acid metabolism gene expression (p < 0.05 vs. sham), downstream of PPARα. Fenofibrate treatment increased fatty acid metabolism further, which reduced post-burn hepatic steatosis (burn vs. sham p < 0.05, burn+fenofibrate vs. sham not significant). Conclusions Fenofibrate did not alleviate thermal injury induced hepatic ER stress and dysfunction but reduced hepatic steatosis by modulating hepatic genes related to fat metabolism. PMID:23866789

Burns are a common type of skin injury encountered at all levels of medical facilities from private clinics to core hospitals. Minor burns heal by topical treatment alone, but moderate to severe burns require systemic management, and skin grafting is often necessary also for topical treatment. Inappropriate initial treatment or delay of initial treatment may exert adverse effects on the subsequent treatment and course. Therefore, accurate evaluation of the severity and initiation of appropriate treatment are necessary. The Guidelines for the Management of Burn Injuries were issued in March 2009 from the Japanese Society for Burn Injuries as guidelines concerning burns, but they were focused on the treatment for extensive and severe burns in the acute period. Therefore, we prepared guidelines intended to support the appropriate diagnosis and initial treatment for patients with burns that are commonly encountered including minor as well as moderate and severe cases. Because of this intention of the present guidelines, there is no recommendation of individual surgical procedures. © 2016 Japanese Dermatological Association.

Improved Survival of Patients With Extensive Burns: Trends in Patient Characteristics and Mortality Among Burn Patients in a Tertiary Care Burn Facility, 2004-2013.

PubMed

Strassle, Paula D; Williams, Felicia N; Napravnik, Sonia; van Duin, David; Weber, David J; Charles, Anthony; Cairns, Bruce A; Jones, Samuel W

Classic determinants of burn mortality are age, burn size, and the presence of inhalation injury. Our objective was to describe temporal trends in patient and burn characteristics, inpatient mortality, and the relationship between these characteristics and inpatient mortality over time. All patients aged 18 years or older and admitted with burn injury, including inhalation injury only, between 2004 and 2013 were included. Adjusted Cox proportional hazards regression models were used to estimate the relationship between admit year and inpatient mortality. A total of 5540 patients were admitted between 2004 and 2013. Significant differences in sex, race/ethnicity, burn mechanisms, TBSA, inhalation injury, and inpatient mortality were observed across calendar years. Patients admitted between 2011 and 2013 were more likely to be women, non-Hispanic Caucasian, with smaller burn size, and less likely to have an inhalation injury, in comparison with patients admitted from 2004 to 2010. After controlling for patient demographics, burn mechanisms, and differential lengths of stay, no calendar year trends in inpatient mortality were detected. However, a significant decrease in inpatient mortality was observed among patients with extensive burns (≥75% TBSA) in more recent calendar years. This large, tertiary care referral burn center has maintained low inpatient mortality rates among burn patients over the past 10 years. While observed decreases in mortality during this time are largely due to changes in patient and burn characteristics, survival among patients with extensive burns has improved.

Mix of ablator material into fuel of an ICF capsule adds non-burning material, diluting the fuel and reducing burn. The amount of the reduction is dependent in part on the morphology of the mix. A probability distribution function (PDF) burn model has been developed [6] that utilizes the average concentration of mixed materials as well as the variance in this quantity across cells provided by the BHR turbulent transport model [3] and its revisions [4] to describe the mix in terms of a PDF of concentrations of fuel and ablator material, and provides the burn rate in mixed material. Workmore » is underway to develop the MARBLE ICF platform for use on the National Ignition Facility in experiments to quantify the influence of heterogeneous mix on fusion burn. This platform consists of a plastic (CH) capsule filled with a deuterated plastic foam (CD) with a density of a few tens of milligrams per cubic centimeter, with tritium gas filling the voids in the foam. This capsule will be driven using x-ray drive on NIF, and the resulting shocks will induce turbulent mix that will result in the mixing of deuterium from the foam with the tritium gas. In order to affect the morphology of the mix, engineered foams with voids of diameter up to 100 microns will be utilized. The degree of mix will be determined from the ratio of DT to DD neutron yield. As the mix increases, the yield from reactions between the deuterium of the CD foam with tritium from the gas will increase. Lastly, the ratio of DT to DD neutrons will be compared to a variation of the PDF burn model that quantifies reactions from initially separated reactants.« less

Our facility has seen an increase in the number of cases of children burned in restaurants. Fieldwork has revealed many unsafe serving practices in restaurants in our tristate area. The current research targets what appears to be an underexamined burn-risk environment, restaurants, to examine server knowledge about burn prevention and burn care with customers. Participants included 71 local restaurant servers and 53 servers from various restaurants who were recruited from undergraduate courses. All participants completed a brief demographic form as well as a Burn Knowledge Questionnaire. It was found that server knowledge was low (ie, less than 50% accuracy). Yet, most servers reported that they felt customer burn safety was important enough to change the way that they serve. Additionally, it was found that length of time employed as a server was a significant predictor of servers' burn knowledge (ie, more years serving associated with higher knowledge). Finally, individual items were examined to identify potential targets for developing prevention programs.

How is the chlorophyll count affected by burned and unburned marsh areas?

Does marsh burnings, either man made or natural, hinder or help Louisiana's vitally important coastal plant life? Does the carbon produced from the fires have a negative effect on the chlorophyll count of these precious living protective barriers? Or does it help contribute to raising the plants chlorophyll count? Along Louisiana's Gulf Coast, marsh burnings are conducted every 2-4 years to destroy some of the Spartina patens. Fires and smoke may have an effect on the chlorophyll count of the plants found in Louisiana's marshes. Peat burns, root burns, and cover burns are the three types of marsh fires. These burns can be either man made or started by natural causes. Peat burns occur when the soil is dry due to a drained marsh. Root burns occur when plant roots are burned without the soil being consumed. Cover burns occur when several centimeters of water covers the soil. Cover burns are often used by Wildlife and Fisheries personnel to promote preferred plant food growth like Scirpus olneyi rather than the dominant Spartina patens. Our project was conducted by testing marsh plants and obtaining chlorophyll count of both a burned (cover burn) and an unburned area. Approximately one year after the burn, in August 2015, we tested the burned area's site. We retested the same site in December 2016. The results from our testing showed that there was a slightly higher chlorophyll count in the burned area. The chlorophyll count average from the two testing days was 33.5 in the burned area and 30.15 in the unburned area. Our hypothesis was that the chlorophyll content of "controlled" burned wetland areas will have a higher amount than the "no" burn area. The experiment results supported this hypothesis by showing an increase of 3.35 average in the burned area.

Singapore General Hospital (SGH) is a regional burns centre in Southeast Asia and is the only dedicated burns facility providing specialized burns care in Singapore. A cohort study was performed for burns patients admitted to SGH from 2011 to 2013. We compared our data with earlier studies and observed the trends of burns epidemiology in Singapore. Results were analyzed using the SPSS programme. 655 patients were admitted during this study period, a 35.9% increase from 2003 to 2005. Scalding by water and flame injury remain the top causes of burns and the mean extent of burn is 9.5%. TBSA correlates with the incidence of burn infection, bacteremia and mortality. Patients with ≥20% TBSA are at a higher risk of bacteremia, and ≥ 34% TBSA is a predictor of mortality. 4.9% (n=32) of our patients developed bacteremia. Bacteremia was associated with a surgical duration of ≥80min. Patients with bacteremia incurred longer hospitalization, and had higher mortality rates. Overall mortality rate of our burns patients has decreased from 4.5% to 2.7% (n=18). Key factors of mortality include inhalational injury, bacteremia and ≥20% TBSA. This is a large epidemiology study of a tropical region burns centre. A total of 655 burns cases over a 3-year period were analyzed. We analysed the key factors associated with adverse outcomes including burns infection, bacteremia and mortality, factors associated with mortality, and discussed strategies on the optimization of burns care.

Root litter decomposition is a major component of carbon (C) cycling in grasslands, where it provides energy and nutrients for soil microbes and fauna. This is especially important in grasslands where fire is a common management practice and removes aboveground litter accumulation. In this study, we investigated whether fire affects root decomposition and C flow through the belowground food web. In a greenhouse experiment, we applied 13C-enriched big bluestem (Andropogon gerardii) root litter to intact tallgrass prairie soil cores collected from annually burned (AB) and infrequently burned (IB) treatments at the Konza Prairie Long Term Ecological Research (LTER) site. Incorporation of 13C into microbial phospholipid fatty acids and nematode trophic groups was measured on six occasions during a 180-day decomposition study to determine how C was translocated through the soil food web. Results showed significantly different soil communities between treatments and higher microbial abundance for IB. Root decomposition occurred rapidly and was significantly greater for AB. Microbes and their nematode consumers immediately assimilated root litter C in both treatments. Root litter C was preferentially incorporated in a few groups of microbes and nematodes, but depended on burn treatment: fungi, Gram-negative bacteria, Gram-positive bacteria, and fungivore nematodes for AB and only omnivore nematodes for IB. The overall microbial pool of root litter-derived C significantly increased over time but was not significantly different between burn treatments. The nematode pool of root litter-derived C also significantly increased over time, and was significantly higher for the AB treatment at 35 and 90 days after litter addition. In conclusion, the C flow from root litter to microbes to nematodes is not only measurable, but significant, indicating that higher nematode trophic levels are critical components of C flow during root decomposition which, in turn, is significantly

Burning plasma regime for Fussion-Fission Research Facility

The basic aspects of burning plasma regimes of Fusion-Fission Research Facility (FFRF, R/a=4/1 m/m, Ipl=5 MA, Btor=4-6 T, P^DT=50-100 MW, P^fission=80-4000 MW, 1 m thick blanket), which is suggested as the next step device for Chinese fusion program, are presented. The mission of FFRF is to advance magnetic fusion to the level of a stationary neutron source and to create a technical, scientific, and technology basis for the utilization of high-energy fusion neutrons for the needs of nuclear energy and technology. FFRF will rely as much as possible on ITER design. Thus, the magnetic system, especially TFC, will take advantage of ITER experience. TFC will use the same superconductor as ITER. The plasma regimes will represent an extension of the stationary plasma regimes on HT-7 and EAST tokamaks at ASIPP. Both inductive discharges and stationary non-inductive Lower Hybrid Current Drive (LHCD) will be possible. FFRF strongly relies on new, Lithium Wall Fusion (LiWF) plasma regimes, the development of which will be done on NSTX, HT-7, EAST in parallel with the design work. This regime will eliminate a number of uncertainties, still remaining unresolved in the ITER project. Well controlled, hours long inductive current drive operation at P^DT=50-100 MW is predicted.

Children 5 and younger are at risk for sustaining serious burn injuries. The causes of burns vary depending on demographic, cultural and socioeconomic variables. At this pediatric burn center we provided medical care to children from Mexico with severe injuries. The purpose of this study was to understand the impact of demographic distribution and modifiable risk factors of burns in young children to help guide prevention. A retrospective chart review was performed with children 5 and younger from Mexico who were injured from 2000-2013. The medical records of 447 acute patients were reviewed. Frequency counts and percentages were used to identify geographic distribution and calculate incidence of burns. Microsoft Powermap software was used to create a geographical map of Mexico based on types of burns. A binomial logistic regression was used to model the incidence of flame burns as opposed to scald burns in each state with relation to population density and poverty percentage. In all statistical tests, alpha=0.05 for a 95% level of confidence. Burns were primarily caused by flame and scald injuries. Admissions from flame injuries were mainly from explosions of propane tanks and gas lines and house fires. Flame injuries were predominantly from the states of Jalisco, Chihuahua, and Distrito Federal. Scalds were attributed to falling in large containers of hot water or food on the ground, and spills of hot liquids. Scald injuries were largely from the states of Oaxaca, Distrito Federal, and Hidalgo. The odds of a patient having flame burns were significantly associated with poverty percentage (p<0.0001) and population density (p=0.0085). Increasing levels of poverty led to decrease in odds of a flame burn, but an increase in the odds of scald burns. Similarly, we found that increasing population density led to a decrease in the odds of a flame burn, but an increase in the odds of a scald burn.

Critical issues in burn care.

PubMed

Holmes, James H

2008-01-01

Burn care, especially for serious burn injuries, represents a considerable challenge for the healthcare system. The American Burn Association has established a number of strategies for the management of burn patients and dedicates its efforts and resources to promoting and supporting burn-related research, education, care, rehabilitation, and prevention, often in collaboration with other organizations. The American Burn Association has recommended that patients with serious burns be referred to a designated burn center, ie, a hospital outfitted with specialized personnel and equipment dedicated to burn care. Burn centers have been operational for over 50 years, but the complexity and costs of providing specialized burn care have given rise to a number of critical administrative and political issues. These include logistical limitations imposed by the uneven national distribution of burn centers and a potential shortage of burn beds, both during everyday conditions and in the event of a mass disaster. Burn surgeon shortages have also been identified, stemming, in part, from a lack of specialized burn care training opportunities. There is currently a lack of quality outcome data to support evidence-based recommendations for burn care, and burn care centers are compromised by problems obtaining reimbursement for the care of uninsured and publicly insured out-of-state burn patients. Initiatives are underway to maintain efficient burn care facilities that are fully funded, easily accessible, and most importantly, provide optimal, evidence-based care on a daily basis, and are well-equipped to handle a surge of patients during a disaster situation.

Prescribed burning (PB) is gaining popularity as a low-cost forest protection measure that efficiently reduces fuel build-up, but its effects on tree health and growth are poorly understood. Here, we evaluated the impact of PB on plant defenses in Mediterranean pine forests (Pinus halepensis and P. nigra ssp. laricio). These chemical defenses were estimated based on needle secondary metabolites (terpenes and phenolics including flavonoids) and discussed in terms of chlorophyll fluorescence and soil nutrients. Three treatments were applied: absence of burning (control plots); single burns (plots burned once); and repeated burns (plots burned twice). For single burns, we also explored changes over time. In P. laricio, PB tended to trigger only minor modifications consisting exclusively of short-lived increases (observed within 3 months after PB) in flavonoid index, possibly due to the leaf temperature increase during PB. In P. halepensis, PB had detrimental effects on physiological performance, consisting of (i) significant decreases in actual PSII efficiency (ΦPSII) in light-adapted conditions after repeated PB, and (ii) short-lived decreases in variable-to-maximum fluorescence ratio (Fv/Fm) after single PB, indicating that PB actually stressed P. halepensis trees. Repeated PB also promoted terpene-like metabolite production, which increased 2 to 3-fold compared to control trees. Correlations between terpene metabolites and soil chemistry were found. These results suggest that PB impacts needle secondary metabolism both directly (via a temperature impact) and indirectly (via soil nutrients), and that these impacts vary according to species/site location, frequency and time elapsed since last fire. Our findings are discussed with regard to the use of PB as a forest management technique and its consequences on plant investment in chemical defenses.

Clothing burns in Canadian children

Stanwick, Richard S.

1985-01-01

A Canadian survey of 11 tertiary care pediatric centres with specialized burn facilities revealed that an estimated 37 children up to 9 years of age are admitted annually to such hospitals because of clothing burns. Sleepwear accounts for an estimated 21 such burns per year. Girls were found to suffer the most severe burns and represented eight of the nine children in the series who died. Loose and flowing garments dominated the girls' styles. The results of multiple-regression analysis confirmed that style of clothing (loose and flowing as opposed to snug) was the most significant predictor of burn severity, length of hospital stay, the need for skin grafting and survival. The ignition situation (avoidance of parental supervision at the time of injury) was the only other important predictor. The success of regulatory actions in other countries in reducing the incidence of severe clothing burns is reviewed, and preventive strategies for Canada are explored. ImagesFig. 2 PMID:3995433

2013-01-01

Aim: To determine the types of functional disabilities in adult and paediatric burns survivors, with specific emphasis on potential risk and socio-economic factors of burn disabilities present in Ghana. Patients and Methods: The descriptive study was carried out in Komfo Anokye Teaching Hospital, Kumasi, Ghana from May 2011 to April 2012. Burn survivors who came for follow-up visits after been discharged home and had functional disability were the participants of the study. They were physically examined and interviewed using a pre-tested questionnaire after their informed consent/or that of their parents (in the cases of paediatrics burns survivors) was sought. Results: A total of 70 participants consented for the study. Their ages ranged from 8/12 – 78 years, with a mean age of 12±1.7 years. Majority (60.0%, N=42) of the participants had third degree burns. The nature of disabilities of participants were mostly scar contractures (42.9%, N=30) of which 36.7% (N=11) had impeded arm elevation; 23.3% (N=7) could not fold the palm or move the digits. From the multiple regression analysis risk factors for burn victim to have disability were paediatric age (OR=11.1, P=0.043), third degree of burn (OR=6.2, P=0.001) and anatomical part affected (OR=18.3, P=0.031). Socio-economic factors that affected burn disability victims were nuclear family compensation (OR=4.2, P=0.021), community mockery/stigmatization (OR=0.1, P=0.052) and caretakers time and finance (OR=5.2, P=0.033). Conclusion: The commonest functional disabilities recorded were scar contractions of the axilla region which had impeded the ability of the patients to lift the arm. Risk factors for burns disability included childhood age, third degree of burn incurred and anatomical part affected. Social factors influencing the lives of burn survivors with disability were good family and negative community interactions. Significant economical factors recorded were caretakers’ time and financial constrains. PMID

A preliminary investigation of the burn rehabilitation population found a large variability of zero onset day frequency between facilities. Onset days is defined as the time from injury to inpatient rehabilitation admission; this variable has not been investigated in burn patients previously. This study explored if this finding was a facility-based phenomena or characteristic of burn inpatient rehabilitation patients. This study was a secondary analysis of Uniform Data System for Medical Rehabilitation (UDSmr) data from 2002 to 2007 examining inpatient rehabilitation characteristics among patients with burn injuries. Exclusion criteria were age less than 18 years and discharge against medical advice. Comparisons of demographic, medical and functional data were made between facilities with a high frequency of zero onset days versus facilities with a low frequency of zero onset days. A total of 4738 patients from 455 inpatient rehabilitation facilities were included. Twenty-three percent of the population exhibited zero onset days (n = 1103). Sixteen facilities contained zero onset patients; two facilities accounted for 97% of the zero onset subgroup. Facilities with a high frequency of zero onset day patients demonstrated significant differences in demographic, medical, and functional variables compared to the remainder of the study population. There were significantly more zero onset day admissions among burn patients (23%) than other diagnostic groups (0.5- 3.6%) in the Uniform Data System for Medical Rehabilitation database, but the majority (97%) came from two inpatient rehabilitation facilities. It is unexpected for patients with significant burn injury to be admitted to a rehabilitation facility on the day of injury. Future studies investigating burn rehabilitation outcomes using the Uniform Data System for Medical Rehabilitation database should exclude facilities with a high percentage of zero onset days, which are not representative of the burn inpatient

A Burning Plasma Experiment: the role of international collaboration

NASA Astrophysics Data System (ADS)

Prager, Stewart

2003-04-01

The world effort to develop fusion energy is at the threshold of a new stage in its research: the investigation of burning plasmas. A burning plasma is self-heated. The 100 million degree temperature of the plasma is maintained by the heat generated by the fusion reactions themselves, as occurs in burning stars. The fusion-generated alpha particles produce new physical phenomena that are strongly coupled together as a nonlinear complex system, posing a major plasma physics challenge. Two attractive options are being considered by the US fusion community as burning plasma facilities: the international ITER experiment and the US-based FIRE experiment. ITER (the International Thermonuclear Experimental Reactor) is a large, power-plant scale facility. It was conceived and designed by a partnership of the European Union, Japan, the Soviet Union, and the United States. At the completion of the first engineering design in 1998, the US discontinued its participation. FIRE (the Fusion Ignition Research Experiment) is a smaller, domestic facility that is at an advanced pre-conceptual design stage. Each facility has different scientific, programmatic and political implications. Selecting the optimal path for burning plasma science is itself a challenge. Recently, the Fusion Energy Sciences Advisory Committee recommended a dual path strategy in which the US seek to rejoin ITER, but be prepared to move forward with FIRE if the ITER negotiations do not reach fruition by July, 2004. Either the ITER or FIRE experiment would reveal the behavior of burning plasmas, generate large amounts of fusion power, and be a huge step in establishing the potential of fusion energy to contribute to the world's energy security.

This research explored the gender differences in resilience and psychological distress of patients with burns. In Pakistan, psychological states of patients with burns have not been widely studied, women making up as the neglected section of society lag far behind in availing the needful health facilities. It was hypothesized that there would be significant gender differences in resilience and psychological distress of patients with burns. The sample of the study consisted of 50 patients with burns, obtained from four different hospitals of Lahore. In order to investigate resilience and psychological distress, the State Trait Resilience Scales (Hiew, 2007) and Kessler Psychological Distress Scale (Kessler, 2001) were used. In addition to these, self-constructed demographic questionnaire was administered. The data was analyzed using SPSS version 16.0. Independent sample t-test was conducted to find gender differences in resilience and psychological distress. The findings from the current research revealed that there were significant gender differences in resilience and psychological distress of patients with burns. The insightful findings from the current research carry strong implications for the clinicians, psychologists and policy makers who can help to develop and implement the rehabilitation programs for the affected population and can launch resilience promoting programs that would help them in coping with burns in effective manner.

In 2005, the American Burn Association published burn disaster guidelines. This work recognized that local and state assets are the most important resources in the initial 24- to 48-hour management of a burn disaster. Historical experiences suggest there is ample opportunity to improve local and state preparedness for a major burn disaster. This review will focus on the basics of developing a burn surge disaster plan for a mass casualty event. In the event of a disaster, burn centers must recognize their place in the context of local and state disaster plan activation. Planning for a burn center takes on three forms; institutional/intrafacility, interfacility/intrastate, and interstate/regional. Priorities for a burn disaster plan include: coordination, communication, triage, plan activation (trigger point), surge, and regional capacity. Capacity and capability of the plan should be modeled and exercised to determine limitations and identify breaking points. When there is more than one burn center in a given state or jurisdiction, close coordination and communication between the burn centers are essential for a successful response. Burn surge mass casualty planning at the facility and specialty planning levels, including a state burn surge disaster plan, must have interface points with governmental plans. Local, state, and federal governmental agencies have key roles and responsibilities in a burn mass casualty disaster. This work will include a framework and critical concepts any burn disaster planning effort should consider when developing future plans.

Chemical burns can lead to serious health outcomes. Previous studies about chemical burns have been performed based on burn center data so these studies have provided limited information about the incidence of chemical burns at the national level. The aim of this study was to evaluate the incidence and characteristics of chemical burns using nationwide databases. A cohort representing the Korean population, which was established using a national health insurance database, and a nationwide workers' compensation database were used to evaluate the incidence and characteristics of chemical burns. Characteristics of the affected body region, depth of burns, industry, task, and causative agents were analyzed from two databases. The incidence of chemical burns was calculated according to employment status. The most common regions involving chemical burns with hospital visits were the skin followed by the eyes. For skin lesions, the hands and wrists were the most commonly affected regions. Second degree burns were the most common in terms of depth of skin lesions. The hospital visit incidence was 1.96 per 10,000 person-year in the general population. The compensated chemical burns incidence was 0.17 per 10,000 person-year. Employees and the self-employed showed a significantly increased risk of chemical burns undergoing hospital visits compared to their dependents. Chemical burns on the skin and eyes are almost equally prevalent. The working environment was associated with increased risk of chemical burns. Our results may aid in estimating the size of the problem and prioritizing prevention of chemical burns. Copyright © 2016 Elsevier Ltd and ISBI. All rights reserved.

This paper presents results of the AQL2004 project, which has been develope within the GOFC-GOLD Latin American network of remote sensing and forest fires (RedLatif). The project intended to obtain monthly burned-land maps of the entire region, from Mexico to Patagonia, using MODIS (moderate-resolution imaging spectroradiometer) reflectance data. The project has been organized in three different phases: acquisition and preprocessing of satellite data; discrimination of burned pixels; and validation of results. In the first phase, input data consisting of 32-day composites of MODIS 500-m reflectance data generated by the Global Land Cover Facility (GLCF) of the University of Maryland (College Park, Maryland, U.S.A.) were collected and processed. The discrimination of burned areas was addressed in two steps: searching for "burned core" pixels using postfire spectral indices and multitemporal change detection and mapping of burned scars using contextual techniques. The validation phase was based on visual analysis of Landsat and CBERS (China-Brazil Earth Resources Satellite) images. Validation of the burned-land category showed an agreement ranging from 30% to 60%, depending on the ecosystem and vegetation species present. The total burned area for the entire year was estimated to be 153 215 km2. The most affected countries in relation to their territory were Cuba, Colombia, Bolivia, and Venezuela. Burned areas were found in most land covers; herbaceous vegetation (savannas and grasslands) presented the highest proportions of burned area, while perennial forest had the lowest proportions. The importance of croplands in the total burned area should be taken with reserve, since this cover presented the highest commission errors. The importance of generating systematic products of burned land areas for different ecological processes is emphasized.

Humanitarian organizations care for burns during crisis and while supporting healthcare facilities in low-income and middle-income countries. This study aimed to define the epidemiology of burn-related procedures to aid humanitarian response. In addition, operational data collected from humanitarian organizations are useful for describing surgical need otherwise unmet by national health systems. Procedures performed in operating theatres run by Médecins Sans Frontières-Operations Centre Brussels (MSF-OCB) from July 2008 through June 2014 were reviewed. Surgical specialist missions were excluded. Burn procedures were quantified, related to demographics and reason for humanitarian response, and described. A total of 96,239 operations were performed at 27 MSF-OCB projects in 15 countries between 2008 and 2014. Of the 33,947 general surgical operations, 4,280 (11%) were for burns. This proportion steadily increased from 3% in 2008 to 24% in 2014. People receiving surgical care from conflict relief missions had nearly twice the odds of having a burn operation compared with people requiring surgery in communities affected by natural disaster (adjusted odds ratio, 1.94; 95% confidence interval, 1.46-2.58). Nearly 70% of burn procedures were planned serial visits to the theatre. A diverse skill set was required. Unmet humanitarian assistance needs increased US$400 million dollars in 2013 in the face of an increasing number of individuals affected by crisis and a growing surgical burden. Given the high volume of burn procedures performed at MSF-OCB projects and the resource intensive nature of burn management, requisite planning and reliable funding are necessary to ensure quality for burn care in humanitarian settings.

Release of PCDD and PCDF from biomass combustion such as forest and agricultural crop fires has been nominated as an important source for these chemicals despite minimal characterisation. Available emission factors that have been experimentally determined in laboratory and field experiments vary by several orders of magnitude from <0.5 μg TEQ (t fuel consumed)(-1) to >100 μg TEQ (t fuel consumed)(-1). The aim of this study was to evaluate the effect of experimental methods on the emission factor. A portable field sampler was used to measure PCDD/PCDF emissions from forest fires and the same fuel when burnt over a brick hearth to eliminate potential soil effects. A laboratory burn facility was used to sample emissions from the same fuels. There was very good agreement in emission factors to air (EF(Air)) for forest fuel (Duke Forest, NC) of 0.52 (range: 0.40-0.79), 0.59 (range: 0.18-1.2) and 0.75 (range: 0.27-1.2) μg TEQ(WHO2005) (t fuel consumed)(-1) for the in-field, over a brick hearth, and burn facility experiments, respectively. Similarly, experiments with sugarcane showed very good agreement with EF(Air) of 1.1 (range: 0.40-2.2), 1.5 (range: 0.84-2.2) and 1.7 (range: 0.34-4.4) μg TEQ (t fuel consumed)(-1) for in-field, over a brick hearth, open field and burn facility experiments respectively. Field sampling and laboratory simulations were in good agreement, and no significant changes in emissions of PCDD/PCDF could be attributed to fuel storage and transport to laboratory test facilities.

The individual implications of major burns are likely to affect the full spectrum of patients' physical, emotional, psychological, social, environmental, spiritual and vocational health. Yet, not all of the post-burn health implications are inevitably negative. Utilizing a qualitative approach, this heuristic phenomenological study explores the experiences and perceptions early (ages 18-35) and midlife (ages 36-64) adults providing insight for how participants perceived their burns in relationship to their post-burn health. Participants were interviewed using semi-structured interview questions framed around seven domains of health. Interview recordings were transcribed verbatim then coded line by line, identifying dominant categories related to health. Categories were analyzed identifying shared themes among the study sample. Participants were Caucasian, seven males and one female. Mean age at time of interviews was 54.38 and 42.38 at time of burns. Mean time since burns occurred was 9.38 years with a minimum of (20%) total body surface area (TBSA) burns. Qualitative content analysis rendered three emergent health-related categories and associated themes that represented shared meanings within the participant sample. The category of "Physical Health" reflected the theme physical limitations, pain and sensitivity to temperature. Within the category of "Intellectual Health" were themes of insight, goal setting and self-efficacy, optimism and humor and within "Emotional Health" were the themes empathy and gratitude. By exploring subjective experiences and perceptions of health shared through dialog with experienced burned persons, there are opportunities to develop a more complete picture of how holistic health may be affected by major burns that in turn could support future long-term rehabilitative trajectories of early and midlife adult burn patients.

How is Biomass Burning Affected by Grazing and Drought in Central and Western Asia?

NASA Astrophysics Data System (ADS)

Biomass burning is a recurring natural process in many ecosystems and most of the fires are caused by human activity. The trace gases, aerosol particles, and black carbon emitted from biomass fires can affect air quality, climate, and public health. In addition, black carbon emitted from wildfires in high latitudes transports and is deposited in the Arctic, accelerating the ice and snow melt. As the climate becomes warmer and drier, more wildfires will occur in high-latitude ecosystems, a region highly sensitive to global warming. We mapped the area burned daily in Northern Eurasia at a 500m x 500m resolution from 2002 to 2015 in different ecosystems over different geographic regions. The mapping was based on the MODIS (MODerate Resolution Imaging Spectroradiometer) products from NASA Terra and Aqua satellites. From the Northern Eurasia dataset, we report the driving forces for the inter-annual variability of fire activity in Central and Western Asia during a period of 14 years from 2002 to 2015. Grassland dominated the region (>95%). Our results showed the area burned in this region has decreased about 65% from 1.4 x 105 km2 in 2002 to 0.5 x 105 km2 in 2015 during this period. The decrease is correlated with (1) the decrease of MODIS Drought Severity Index (DSI), and (2) the increase of the number of goats, sheep and cattle. The DSI decreased substantially from +1.0 in 2002 to -0.4 in 2011. The numbers of grazers in this region have decreased drastically in the mid-1990s because of economic collapse of the Soviet Union. However, the number of grazers have recovered and have increased steadily since 2000. Grazing by domestic animals on grassland reduces fuel loadings and thus emissions from biomass burning. The interactions of drought-economy-grazing-extent of biomass burning-emissions of black carbon and atmospheric pollutants in Central and Western Asia in the past 14 years will be summarized.

In a ten year retrospective study of burns in children in University of Calabar Teaching Hospital (UCTH), Calabar, the main causes were hot water, hot soup or oil (56.6%) involving children mostly in the one to three year age group. The relative safety of the home environment seen in other forms of paediatric trauma is not observed in burns in children. A changing pattern of burns in children has emerged within the region with naked flames/bush fire coming second and affecting 22.7% of the children. Chemical burns hitherto a rare occurrence is now frequent because of the storage of caustic soda and acids in living rooms by soap making parents. Burns affecting the perineum, axilla and buttocks are difficult to keep clean and frequently lead to infections, with associated increased morbidity. Causes of childhood burns are largely preventable requiring active social/medical education and public enlightenment campaigns on the various methods of prevention.

Land cover and topography affect the land transformation caused by wind facilities

Land transformation (ha of surface disturbance/MW) associated with wind facilities shows wide variation in its reported values. In addition, no studies have attempted to explain the variation across facilities. We digitized land transformation at 39 wind facilities using high resolution aerial imagery. We then modeled the effects of turbine size, configuration, land cover, and topography on the levels of land transformation at three spatial scales. The scales included strings (turbines with intervening roads only), sites (strings with roads connecting them, buried cables and other infrastructure), and entire facilities (sites and the roads or transmission lines connecting them to existing infrastructure). An information theoretic modeling approach indicated land cover and topography were well-supported variables affecting land transformation, but not turbine size or configuration. Tilled landscapes, despite larger distances between turbines, had lower average land transformation, while facilities in forested landscapes generally had the highest land transformation. At site and string scales, flat topographies had the lowest land transformation, while facilities on mesas had the largest. The results indicate the landscape in which the facilities are placed affects the levels of land transformation associated with wind energy. This creates opportunities for optimizing wind energy production while minimizing land cover change. In addition, the results indicate forecasting the impacts of wind energy on land transformation should include the geographic variables affecting land transformation reported here.

Summary The first aid for burns is to run cold water over the burn for 20 minutes. This is effective for up to three hours after the injury. Assess the affected body surface area using the rule of nines. Consult a burn unit if more than 5% of the total body surface area is burnt in a child or if more than 10% in an adult. Extensive or deep burns and burns to special areas, such as the hands, should be referred. Chemical or electrical burns should also be assessed by a burn unit. For minor burns, antimicrobial dressings are recommended, but oral antibiotics should be avoided unless there are signs of infection. As burns are tetanus prone, check the patient’s immunisation status. Burns that become infected or are slow to heal should be discussed with a burn unit. The burn unit can also provide advice if there are uncertainties about how to manage a patient. PMID:26648640

Factors affecting the abundance of leaf-litter arthropods in unburned and thrice-burned seasonally-dry Amazonian forests.

Silveira, Juliana M; Barlow, Jos; Louzada, Julio; Moutinho, Paulo

2010-09-21

Fire is frequently used as a land management tool for cattle ranching and annual crops in the Amazon. However, these maintenance fires often escape into surrounding forests, with potentially severe impacts for forest biodiversity. We examined the effect of experimental fires on leaf-litter arthropod abundance in a seasonally-dry forest in the Brazilian Amazon. The study plots (50 ha each) included a thrice-burned forest and an unburned control forest. Pitfall-trap samples were collected at 160 randomly selected points in both plots, with sampling stratified across four intra-annual replicates across the dry and wet seasons, corresponding to 6, 8, 10 and 12 months after the most recent fire. Arthropods were identified to the level of order (separating Formicidae). In order to better understand the processes that determine arthropod abundance in thrice-burned forests, we measured canopy openness, understory density and litter depth. All arthropod taxa were significantly affected by fire and season. In addition, the interactions between burn treatment and season were highly significant for all taxa but Isoptera. The burned plot was characterized by a more open canopy, lower understory density and shallower litter depth. Hierarchical partitioning revealed that canopy openness was the most important factor explaining arthropod order abundances in the thrice-burned plot, whereas all three environmental variables were significant in the unburned control plot. These results reveal the marked impact of recurrent wildfires and seasonality on litter arthropods in this transitional forest, and demonstrate the overwhelming importance of canopy-openness in driving post-fire arthropod abundance.

2017-09-01

The O horizon, or detrital layer, of forest soils is linked to long-term forest productivity and health. Fuel reduction techniques, such as prescribed fire, can alter the thickness and composition of this essential ecosystem component. Developing an understanding of the changes in the chemical composition of forest detritus due to prescribed fire is essential for forest managers and stakeholders seeking sustainable, resilient, and productive ecosystems. In this study, we evaluated fuel quantity, fuel structure, and detrital chemical composition in longleaf pine ( Miller) forests that have been frequently burned for the last 40 yr at the Tom Yawkey Wildlife Center in Georgetown, SC. Our results suggest that frequent prescribed fire reduces forest fuel quantity ( < 0.01) and vertical structure ( = 0.01). Using pyrolysis-gas chromatography/mass spectrometry as a molecular technique to analyze detrital chemical composition, including aromatic compounds and polycyclic aromatic hydrocarbons, we found that the chemical composition of forest detritus was nearly uniform for both unburned and burned detritus. Our burning activities varied in the short term, consisting of annual dormant, annual growing, and biennial dormant season burns. Seasonal distinctions were present for fuel quantity and vertical fuel structure, but these differences were not noted for the benzene/phenol ratio. These results are significant as more managers consider burning existing longleaf stands while determining effective management practices for longleaf stands yet to be established. Managers of such stands can be confident that frequent, low-intensity, low-severity prescribed burns in longleaf pine forests do little to affect the long-term chemical composition of forest detritus.

Burns represent a serious problem around the world especially in low- and middle-income countries. The aim was to determine the epidemiological characteristics, causes and mortality rate of burn deaths in the Colombian pediatric population as well as to guide future education and prevention programs. We conducted an observational, analytical, retrospective population-based study. It was based upon official death certificate data using diagnosis codes for burns (scalds, thermal, electrical, intentional self-harm and not specified), that occurred between January 1, 2000 and December 31, 2009. Official death certificates of the pediatric population of up to 15 years of age were obtained from the National Administrative Department of Statistics. A total of 1197 fatal pediatric injuries related to burns were identified. The crude and adjusted mortality rate for burns in the pediatric population in Colombia during the length of the study was 0.899 and 0.912 per 100,000, respectively. The mortality rate tended to decrease (-5.17% annual) during the duration of the study. Children under 5 years of age were the most affected group (59.5%). Almost half of them died before arriving at a health facility (47.1%). Fire is the principal cause of death attributable to burns in Colombia, followed by electric burns and hot liquids. This is a first step study in researching the epidemiological features of pediatric deaths after burns. The Public Health's strategies should be oriented toward community awareness about these kind of injuries, and to teach children and families about risk factors and first aid.

Summary Electrical burn injuries in the paediatric age group constitute a small proportion of all burn cases and cause significant morbidity and long-term psychosocial impact. The objective of this study was to evaluate various aspects of electrical burn injuries in the paediatric age group in our region. A retrospective review was done of all paediatric electrical burns admitted to a tertiary care burns unit over a period of 12 months (January 2016 to December 2016). There were 77 cases of electrical burns under the age of 16 years. High voltage burns predominated and older age groups were more frequently affected. Male:female ratio was 4.1:1. Amputations were required in 18 (23%), skin grafting in 52 (67%) and flap cover in 29 (37%) patients. There were unfavourable outcomes in 32% patients with a mortality rate of 7.8%. Significant association was found between unfavourable outcomes and high voltage burn injuries and length of hospital stay. The impact of electrical burn injuries is substantial and can be reduced by simple preventive measures such as educating parents, improving health infrastructure and adherence to safety regulations.

The regenerative repair of deep-degree (second degree) burned skin remains a notable challenge in the treatment of burn injury, despite improvements being made with regards to treatment modality and the emergence of novel therapies. Fetal skin constitutes an attractive target for investigating scarless healing of burned skin. To investigate the inflammatory response during scarless healing of burned fetal skin, the present study developed a nude mouse model, which was implanted with normal human fetal skin and burned fetal skin. Subsequently, human peripheral blood mononuclear cells (PBMCs) were used to treat the nude mouse model carrying the burned fetal skin. The expression levels of matrix metalloproteinase (MMP)-9 and tissue inhibitor of metalloproteinases (TIMP)-1 were investigated during this process. In the present study, fetal skin was subcutaneously implanted into the nude mice to establish the murine model. Hematoxylin and eosin staining was used to detect alterations in the skin during the development of fetal skin and during the healing process of deep-degree burned fetal skin. The expression levels of MMP-9 and TIMP-1 were determined using immunochemical staining, and their staining intensity was evaluated by mean optical density. The results demonstrated that fetal skin subcutaneously implanted into the dorsal skin flap of nude mice developed similarly to the normal growth process in the womb. In addition, the scarless healing process was clearly observed in the mice carrying the burned fetal skin. A total of 2 weeks was required to complete scarless healing. Following treatment with PBMCs, the burned fetal skin generated inflammatory factors and enhanced the inflammatory response, which consequently resulted in a reduction in the speed of healing and in the formation of scars. Therefore, exogenous PBMCs may alter the lowered immune response environment, which is required for scarless healing, resulting in scar formation. In conclusion, the present

The consequences of global biomass burning

NASA Technical Reports Server (NTRS)

Levine, Joel S.

1991-01-01

Global biomass burning encompasses forest burning for land clearing, the annual burning of grasslands, the annual burning of agricultural stubble and waste after harvests, and the burning of wood as fuel. These activities generate CO2, CH4 and other hydrocarbons, CO, H2, NO, NH3, and CH3Cl; of these, CO, CH4 and the hydrocarbons, and NO, are involved in the photochemical production of tropospheric O3, while NO is transformed to NO2 and then to nitric acid, which falls as acid rain. Biomass burning is also a major source of atmospheric particulates and aerosols which affect the transmission of incoming solar radiation and outgoing IR radiation through the atmosphere, with significant climatic effects.

Resuscitation burn card--a useful tool for burn injury assessment.

PubMed

Malic, C C; Karoo, R O S; Austin, O; Phipps, A

2007-03-01

It is well recognised that the initial assessment of body surface area affected by a burn is often over estimated in Accident and Emergency Departments. A useful aide-memoir in the acute setting is Wallace's "rule of nines" or using the patients' palmar surface of the hand, which approximates 1% of the total body surface area, as a method of assessment. Unfortunately, as with every system, limitations apply. Factors such as patient size and the interpretation of what is exactly the 'palmar surface' may significantly influence burn size estimations and subsequently fluid resuscitation. Our aim is to develop a simple, quick and easy reproducible method of calculating burn injuries for medical professionals in the acute setting. Worldwide, the dimensions of a credit card are standardized (8.5 cm x 5.3 cm), thus producing a surface area of 45 cm2. We created a resuscitation burn card (RBC) using these exact same proportions, upon which a modified body surface area (BSA) nomogram was printed. Knowing the patient height and weight, we calculated the surface area of the card as percentage of total body surface area (TBSA). On the opposite site of the RBC, a Lund and Browder chart was printed, as well as the Parkland formula and a formula to calculate paediatric burn fluid requirements. The plastic, flexible RBC conformed well to the body contour and was designed for single use. We used the resuscitation burn card in the initial assessment of simulated burns in a Regional Burn Centre and in an Accident and Emergency Department. The information present on the card was found to be clear and straightforward to use. The evaluation of burn extent was found to be more accurately measured than the estimation obtained without the RBC. The resuscitation burn card can be a valuable tool in the hands of less experienced medical professionals for the early assessment and fluid resuscitation of a burn.

To attenuate burn-induced catabolism, patients are often enrolled in a resistance exercise program as part of their physical rehabilitation. This study assessed how lower body burn locations affected strength and cardiopulmonary function. Children enrolled in an exercise study between 2003 and 2013, were 7-18 years of age, and burned ≥30% of their total body surface area were included. Analysis of variance was used to model the relationship of lower body strength (PTW) and cardiopulmonary function (VO2peak) due to burns which traverse the subject's lower body joints. There was a significant relationship between PTW and burns at the hip and toe joints, showing a 26 N m/kg (p=0.010) and 33 N m/kg (p=0.013) decrease in peak torque, respectively. Burns at the hip joint corresponded to a significant decrease in VO2peak by 4.9 ml kg(-1) min(-1) (p=0.010) in peak cardiopulmonary function. Physical function and performance are detrimentally affected by burns that traverse specific lower body joints. The most significant relationship on exercise performance was that of hip joint burns as it affected both strength and cardiopulmonary measurements. Ultimately, burns at hip and toe joints need to be considered when interpreting exercise test results involving the lower body. Copyright © 2015 Elsevier Ltd and ISBI. All rights reserved.

Burn-Resistant, Strong Metal-Matrix Composites

NASA Technical Reports Server (NTRS)

Stoltzfus, Joel M.; Tayal, Moti J.

2003-01-01

Ceramic particulate fillers increase the specific strengths and burn resistances of metals: This is the conclusion drawn by researchers at Johnson Space Center's White Sands Test Facility. The researchers had theorized that the inclusion of ceramic particles in metal tools and other metal objects used in oxygen-rich atmospheres (e.g., in hyperbaric chambers and spacecraft) could reduce the risk of fire and the consequent injury or death of personnel. In such atmospheres, metal objects act as ignition sources, creating fire hazards. However, not all metals are equally hazardous: some are more burn-resistant than others are. It was the researchers purpose to identify a burn-resistant, high-specific-strength ceramic-particle/metal-matrix composite that could be used in oxygen-rich atmospheres. The researchers studied several metals. Nickel and cobalt alloys exhibit high burn resistances and are dense. The researchers next turned to ceramics, which they knew do not act as ignition sources. Unlike metals, ceramics are naturally burn-resistant. Unfortunately, they also exhibit low fracture toughnesses.

Burn injuries are one of the leading causes of morbidity and mortality in young children. The Kids' Inpatient Database (KID) and National Burn Repository (NBR) are two large national databases that can be used to evaluate outcomes and help quality improvement in burn care. Differences in the design of the KID and NBR could lead to differing results affecting resultant conclusions and quality improvement programs. This study was designed to validate the use of KID for burn epidemiologic studies, as an adjunct to the NBR. Using the KID (2003, 2006, and 2009), a total of 17,300 nonelective burn patients younger than 20 y old were identified. Data from 13,828 similar patients were collected from the NBR. Outcome variables were compared between the two databases. Comparisons revealed similar patient distribution by gender, race, and burn size. Inhalation injury was more common among the NBR patients and was associated with increased mortality. The rates of respiratory failure, wound infection, cellulitis, sepsis, and urinary tract infection were higher in the KID. Multiple regression analysis adjusting for potential confounders demonstrated similar mortality rate but significantly longer length of stay for patients in the NBR. Despite differences in the design and sampling of the KID and NBR, the overall demographic and mortality results are similar. The differences in complication rate and length of stay should be explored by further studies to clarify underlying causes. Investigations into these differences should also better inform strategies to improve burn prevention and treatment. Copyright © 2016 Elsevier Inc. All rights reserved.

Dreyfuss, U Y

2000-05-01

About 2500 soldiers were injured during the Six Day War (June 1967) of whom 115 suffered from burns. In 34 of them 15% or more of their body surface was involved and 11 died. Typical features of these burn cases were supplementary injuries, a high rate of infection, and long periods of hospitalization. Prophylactic antibiotics were not useful. The general condition of many deteriorated during the first week after injury, indicating the importance of treating severe burns in specialized facilities.

Electrical burns are important causes of trauma worldwide. This study aims to analyze the clinical characteristics, wound management, and outcome of electric burns. This retrospective study was performed at the Institute of Burn Research of the Third Military Medical University during 2013-2015. Data including the demographics, injury patterns, wound treatment, and outcomes were collected and analyzed. A total of 595 electrical burn patients (93.8% males) were included. The average age was 37.3 ± 14.6 y, and most patients (73.5%) were aged 19∼50 years. Most patients (67.2%) were injured in work-related circumstances. The mean total body surface area was 8.8 ± 11.8% and most wounds (63.5%) were full-thickness burns. Operation times of high-voltage burns and current burns were higher than those of low-voltage burns and arc burns, respectively. Of the 375 operated patients, 83.2% (n = 312) underwent skin autografting and 49.3% (n = 185) required skin flap coverage. Common types of skin flaps were adjacent (50.3%), random (42.2%), and pedicle (35.7%). Amputation was performed in 107 cases (18.0%) and concentrated on the hands (43.9%) and upper limbs (39.3%). The mean length of stay was 42.9 ± 46.3 d and only one death occurred (0.2%). Current burns and higher numbers of operations were major risk factors for amputation and length of stay, respectively. Electrical burns mainly affected adult males with occupational exposures in China. Skin autografts and various skin flaps were commonly used for electric burn wound management. More standardized and effective strategies of treatment and prevention are still needed to decrease amputation rates. Copyright © 2017 Elsevier Inc. All rights reserved.

Burn-injury affects gut-associated lymphoid tissues derived CD4+ T cells.

PubMed

Fazal, Nadeem; Shelip, Alla; Alzahrani, Alhusain J

2013-01-01

After scald burn-injury, the intestinal immune system responds to maintain immune balance. In this regard CD4+T cells in Gut-Associated Lymphoid Tissues (GALT), like mesenteric lymph nodes (MLN) and Peyer's patches (PP) respond to avoid immune suppression following major injury such as burn. Therefore, we hypothesized that the gut CD4+T cells become dysfunctional and turn the immune homeostasis towards depression of CD4+ T cell-mediated adaptive immune responses. In the current study we show down regulation of mucosal CD4+ T cell proliferation, IL-2 production and cell surface marker expression of mucosal CD4+ T cells moving towards suppressive-type. Acute burn-injury lead to up-regulation of regulatory marker (CD25+), down regulation of adhesion (CD62L, CD11a) and homing receptor (CD49d) expression, and up-regulation of negative co-stimulatory (CTLA-4) molecule. Moreover, CD4+CD25+ T cells of intestinal origin showed resistance to spontaneous as well as induced apoptosis that may contribute to suppression of effector CD4+ T cells. Furthermore, gut CD4+CD25+ T cells obtained from burn-injured animals were able to down-regulate naïve CD4+ T cell proliferation following adoptive transfer of burn-injured CD4+CD25+ T cells into sham control animals, without any significant effect on cell surface activation markers. Together, these data demonstrate that the intestinal CD4+ T cells evolve a strategy to promote suppressive CD4+ T cell effector responses, as evidenced by enhanced CD4+CD25+ T cells, up-regulated CTLA-4 expression, reduced IL-2 production, tendency towards diminished apoptosis of suppressive CD4+ T cells, and thus lose their natural ability to regulate immune homeostasis following acute burn-injury and prevent immune paralysis.

For the first time in modern history burn centers must face the reality of having to potentially care for a staggering number of injured patients. Factors such as staffing, patient acuity and bed availability compel medical professionals to regularly examine various aspects of their respective healthcare delivery systems, especially with regards to how these systems should function for mass casualty response. The majority of burn care in New Jersey is provided by one designated burn treatment facility. A planning group was formed to identify additional hospital support systems capable of providing short-term patient care during a disaster. Focus was on three key areas: identifying actual versus potential nonburn center resources, ascertaining the number and level of burn expertise at these facilities, and assessing the capacities of any available resources and personnel. Retrospective review of discharge data highlighted which of the more than seventy New Jersey hospitals besides The Burn Center were treating and releasing burn injures. In a disaster The Burn Center designates these hospitals as Tier Facilities to serve as additional resources until patients may be transferred to other recognized regional and national burn centers. Triage is conducted in accordance with the American Burn Association Benefit-to-Ratio Triage grid, matching patient acuity with each hospital's tier designation. A secondary triage, conducted 24 hours after the initial incident, identifies which patients require transport for more specialized burn care. Twenty-seven burn centers from Maine through Maryland and the District of Columbia, who have joined together as a Consortium, agree to support one another for optimal patient distribution and management in accordance with accepted national standards of care. State Medical Coordination Centers equipped to coordinate and track transport of large numbers of injured personnel are able to facilitate this collaborative, multiagency response

Burn injury is one of the most devastating injuries that may affect a patient. Even in economically deprived areas, burn care is largely driven by relatively plentiful resources equating quality of care with generous monitoring and clinical attention with little concern to management cost. Burn care costs have been the subject of very few investigations and are among the least studied by health services researchers. Nevertheless, it can be stated that local care of burn wounds accounts for a large proportion of the cost per day for treating patients. As economic times are changing and as market penetration of managed care contracts and stiff competition in the health care industry gains momentum, ways to reduce expenditures without adversely affecting the quality of care have become of primary importance. We report a randomized prospective comparative study analyzing the benefit-cost value of moist exposed burn ointment (MEBO) application, an exposed method for burn wound care without the need for a secondary covering dressing, as compared to conventional closed methods.

Animal models in burn research.

Abdullahi, A; Amini-Nik, S; Jeschke, M G

2014-09-01

Burn injury is a severe form of trauma affecting more than 2 million people in North America each year. Burn trauma is not a single pathophysiological event but a devastating injury that causes structural and functional deficits in numerous organ systems. Due to its complexity and the involvement of multiple organs, in vitro experiments cannot capture this complexity nor address the pathophysiology. In the past two decades, a number of burn animal models have been developed to replicate the various aspects of burn injury, to elucidate the pathophysiology, and to explore potential treatment interventions. Understanding the advantages and limitations of these animal models is essential for the design and development of treatments that are clinically relevant to humans. This review aims to highlight the common animal models of burn injury in order to provide investigators with a better understanding of the benefits and limitations of these models for translational applications. While many animal models of burn exist, we limit our discussion to the skin healing of mouse, rat, and pig. Additionally, we briefly explain hypermetabolic characteristics of burn injury and the animal model utilized to study this phenomena. Finally, we discuss the economic costs associated with each of these models in order to guide decisions of choosing the appropriate animal model for burn research.

Chile is located in the Ring of Fire, in South America. An earthquake 8.8° affected 80% of the population in February 27th, 2010. This study was conducted to assess any change in burns profile caused by the earthquake. This was an ecologic study. We compared the 4 months following the earthquake in 2009 and 2010. age, TBSA, deep TBSA, agent, specific mortality rate and rate of admissions to the National burn Center of Chile. Mann-Whitney test and a Poisson regression were performed. Age, agent, TBSA and deep TBSA percentages did not show any difference. Mortality rate was lower in 2010 (0.52 versus 1.22 per 1,000,000 habitants) but no meaningful difference was found (Poisson regression p = 0.06). Admission rate was lower in 2010, 4.6 versus 5.6 per 1,000,000 habitants, but no differences were found (p = 0.26). There was not any admissions directly related to the earthquake. As we do not have incidence registries in Chile, we propose to use the rate of admission to the National Burn Reference Center as an incidence estimator. There was not any significant difference in the burn profile, probably because of the time of the earthquake (3 am). We conclude the earthquake did not affect the way the Chilean people get burned.

Accurate burn estimation affects the use of burn resuscitation formulas and treatment strategies, and thus can affect patient outcomes. The objective of this process-improvement project was to compare the accuracy of a computer-based burn mapping program, WoundFlow (WF), with the widely used hand-mapped Lund-Browder (LB) diagram. Manikins with various burn representations (from 1% to more than 60% TBSA) were used for comparison of the WF system and LB diagrams. Burns were depicted on the manikins using red vinyl adhesive. Healthcare providers responsible for mapping of burn patients were asked to perform burn mapping of the manikins. Providers were randomized to either an LB or a WF group. Differences in the total map area between groups were analyzed. Also, direct measurements of the burn representations were taken and compared with LB and WF results. The results of 100 samples, compared using Bland-Altman analysis, showed no difference between the two methods. WF was as accurate as LB mapping for all burn surface areas. WF may be additionally beneficial in that it can track daily progress until complete wound closure, and can automatically calculate burn size, thus decreasing the chances of mathematical errors.

Maternal burn-out is a psychological, emotional and physiological condition resulting from the accumulation of various stressors characterised by a moderate but also a chronic and repetitive dimension. Little research has focused on this syndrome. The current study aims to assess maternal burn-out rate and to identify factors associated with this state of exhaustion. 263 French mothers aged between 20 and 49 years answered five scales quantifying maternal burn-out, perceived social support, parental stress, depression and anxiety symptoms and history of postnatal depression. About 20% of mothers were affected by maternal burn-out. The main factors related to maternal burn-out were having a child perceived as difficult, history of postnatal depression, anxiety, satisfaction of a balance between professional and personal life and parental stress. This research shows the need for further work on maternal burn-out to better understand and prevent this syndrome.

Prescribed burning is commonly used to reduce the risk of severe wildfire. However, further information about the associated environmental effects is required to help forest managers select the most appropriate treatment. To address this question, we evaluated if fire severity during spring prescribed burning significantly affects the resprouting ability of two common shrub species in shrubland under a Mediterranean climate in NW Spain. Fire behaviour and temperatures were recorded in tagged individuals of Erica australis and Pterospartum tridentatum during prescribed burning. The number and length of resprouted shoots were measured three times (6, 12 and 18 months) after the prescribed burning. The influence of a series of fire severity indicators on some plant resprouting vigour parameters was tested by canonical correlation analysis. Six months and one year after prescribed burning, soil burn severity (measured by the absolute reduction in depth of the organic soil layer, maximum temperatures in the organic soil layer and the mineral soil surface during burning and the post-fire depth of the organic soil layer) reduced the resprouting vigour of E. australis and P. tridentatum. In contrast, direct measurements of fire effects on plants (minimum branch diameter, duration of temperatures above 300 °C in the shrub crown and fireline intensity) did not affect the post-fire plant vigour. Soil burn severity during spring prescribed burning significantly affected the short-term resprouting vigour in a mixed heathland in Galicia. The lack of effects eighteen months after prescribed burning indicates the high resilience of these species and illustrates the need to conciliate fire prevention and conservation goals.

An integrated weed management approach requires alternative management practices to herbicide use such as tillage, crop rotations and cultural controls to reduce soil weed seed banks. The objective of this study was to examine the value of different tillage practices and stubble burning to exhaust the seed bank of common weeds from the northern grain region of Australia. Five tillage and burning treatments were incorporated in a field experiment, at Armidale (30 degrees 30'S, 151 degrees 40'E), New South Wales, Australia in July 2004 in a randomized block design replicated four times. The trial was continued and treatments repeated in July 2005 with all the mature plants from the first year being allowed to shed seed in their respective treatment plots. The treatments were (i) no tillage (NT), (ii) chisel ploughing (CP), (iii) mould board ploughing (MBP), (iv) wheat straw burning with no tillage (SBNT) and (v) wheat straw burning with chisel ploughing (SBC). Soil samples were collected before applying treatments and before the weeds flowered to establish the seed bank status of the various weeds in the soil. Wheat was sown after the tillage treatments. Burning treatments were only initiated in the second year, one month prior to tillage treatments. The major weeds present in the seed bank before initiating the trial were Polygonum aviculare, Sonchus oleraceus and Avena fatua. Tillage promoted the germination of other weeds like Hibiscus trionum, Medicago sativa, Vicia sp. and Phalaris paradoxa later in the season in 2004 and Convolvulus erubescens emerged as a new weed in 2005. The MBP treatment in 2004 reduced the weed biomass to a significantly lower level of 55 g/m2 than the other treatments of CP (118 g/m2) and NT plots (196 g/m2) (P < 0.05). However, in 2005 SBC and MBP treatments were similar in reducing the weed biomass. In 2004, the grain yield trend of wheat was significantly different between CP and NT, and MBP and NT (P < 0.05) with maximum yield of 5898

Older patients with burn injury have a greater likelihood for discharge to nursing facilities. Recent research indicates that older patients discharged to nursing facilities are two to three times as likely to die within a 3-year period relative to those discharged to home. In light of these poor long-term outcomes, we conducted this study to identify predictors for discharge to independent vs nonindependent living status in older patients hospitalized for burns. We retrospectively reviewed all older adults (age ≥ 55 years) who were prospectively enrolled in a longitudinal multicenter study of outcomes from 1993 to 2011. Patient, injury, and treatment outcomes data were analyzed. Recognizing that transfer to inpatient rehabilitation may have impacted final hospital discharge disposition: we assessed the likelihood of inpatient rehabilitation stay, based on identified predictors of inpatient rehabilitation. We subsequently performed a logistic regression analysis on the clustered, propensity-matched cohort to assess associations of burn and injury characteristics on the primary outcome of final discharge status. A total of 591 patients aged ≥55 years were treated and discharged alive from three participating U.S. burn centers during the study period. Mean burn size was 14.8% (SD 11.2%) and mean age was 66.7 years (SD 9.3 years). Ninety-three patients had an inpatient rehabilitation stay before discharge (15.7%). Significant factors predictive of inpatient rehabilitation included a burn >20% TBSA, mechanical ventilation, older age, range of motion deficits at acute care discharge, and study site. These factors were included in the propensity model. Four hundred seventy-one patients (80%) were discharged to independent living status. By matched propensity analysis, older age was significantly associated with a higher likelihood of discharge to nonindependent living (P < .01 in both the 65-74 age group and the oldest age group when compared with the 55-64 age group

2004-01-01

During a shuttle launch and other portions of space flight, astronauts wear specialized flame resistant clothing. However during most of their missions on board the Space Shuttle or International Space Station, astronauts wear ordinary clothing, such as cotton shirts and pants. As the behaviour of flames is considerably different in microgravity than under earth s gravity, fabrics are expected to burn in a different fashion in microgravity than when tested on earth. There is interest in determining how this change in burning behaviour may affect times to second and third degree burn of human skin, and how the results of standard fabric flammability tests conducted under earth s gravity correlate with the expected fire behaviour of textiles in microgravity. A new experimental apparatus was developed to fit into the Spacecraft Fire Safety Facility (SFSF), which is used on NASA s KC-135 low gravity aircraft. The new apparatus was designed to be similar to the apparatus used in standard vertical flammability tests of fabrics. However, rather than using a laboratory burner, the apparatus uses a hot wire system to ignite 200 mm high by 80 mm wide fabric specimens. Fabric temperatures are measured using thermocouples and/or an infrared imaging system, while flame spread rates are measured using real time observations or video. Heat flux gauges are placed between 7 and 13 mm away from the fabric specimen, so that heat fluxes from the burning fabric to the skin can be estimated, along with predicted times required to produce skin burns.

Defining the epidemiology and outcome of geriatric burn patients is critical for specialized burn centers, health-care workers, and governments. Better resource use and effective guidelines are some of the advantages of studies focusing on this aspect. The outcome of these patients serves as an objective criterion for quality control, research, and preventive programs. We used data from the burn registry program in our country. For 2 years, >28,700 burn patients were recorded, 1721 of whom were admitted. Among them, 187 patients were ≥55 years old. Sixty-nine percent of patients were male and 31% female, with a male to female ratio of 2.22:1. The mean±standard deviation (SD) of age was 63.4±8.1. The cause of burns was flame (58.2%) and scalds (20.3%). Most of the burns were sustained at home. The mean duration of hospital stay was 19.5 days (range 3-59 days). The mean (SD) of the total body surface area (TBSA) was 20.3% (8.4%). The median hospital stay (length of stay (LOS)) was 11 days (SD=14). The increase in TBSA was related to a longer LOS (p<0.02). Burn wound infection developed in 44.3% of patients. The presence of inhalation injury was significantly related to mortality (p<0.001). Among the patients, 9% recovered completely, 74.9% recovered partially (requiring further treatment), 1% underwent amputation, and 12.8% died. The lack of insurance coverage did not affect the survival of our geriatric burn patients. However, being alone or single, ignition of clothing, cause of burn, comorbid illnesses, complications following the burn, TBSA, age, and sepsis were positively correlated with mortality. The mean cost of treatment for each patient was about $7450. Copyright © 2016 Elsevier Ltd and ISBI. All rights reserved.

Do burn centers provide juvenile firesetter intervention?

2012-01-01

Juvenile firesetting activity accounts for a significant number of annual injuries and property damage, yet there is sparse information on intervention in the burn literature. To quantify juvenile firesetting intervention (JFSI) in burn centers, a 23-question survey was sent to all directors listed in the American Burn Association Burn Care Facilities Directory.Sixty-four out of 112 (57%) surveys were returned. This represents responses from 79% of currently verified burn centers. When queried on interventions provided to a juvenile firesetter admitted to their unit, 38% report having their own JFSI program and 38% refer the child to fire services. Two thirds of units without a JFSI program treat pediatric patients. Units that previously had a JFSI program report lack of staffing and funding as most common reasons for program discontinuation. Almost all (95%) stated that a visual tool demonstrating legal, financial, social, future, and career ramifications associated with juvenile firesetting would be beneficial to their unit. Many burn units that treat pediatric patients do not have JFSI and rely on external programs operated by fire services. Existing JFSI programs vary greatly in structure and method of delivery. Burn centers should be involved in JFSI, and most units would benefit from a new video toolkit to assist in providing appropriate JFSI. Study results highlight a need for burn centers to collaborate on evaluating effectiveness of JFSI programs and providing consistent intervention materials based on outcomes research.

Development of strand burner for solid propellant burning rate studies

Aziz, A.; Mamat, R.; Ali, W. K. Wan

2013-12-01

It is well-known that a strand burner is an apparatus that provides burning rate measurements of a solid propellant at an elevated pressure in order to obtain the burning characteristics of a propellant. This paper describes the facilities developed by author that was used in his studies. The burning rate characteristics of solid propellant have be evaluated over five different chamber pressures ranging from 1 atm to 31 atm using a strand burner. The strand burner has a mounting stand that allows the propellant strand to be mounted vertically. The strand was ignited electrically using hot wire, and the burning time was recorded by electronic timer. Wire technique was used to measure the burning rate. Preliminary results from these techniques are presented. This study shows that the strand burner can be used on propellant strands to obtain accurate low pressure burning rate data.

Communal biofuel burning for district heating: Emissions and immissions from medium-sized (0.4 and 1.5 MW) facilities

NASA Astrophysics Data System (ADS)

Fachinger, Friederike; Drewnick, Frank; Gieré, Reto; Borrmann, Stephan

2018-05-01

Particulate and gaseous emissions of two medium-sized district heating facilities (400 kW, fueled with miscanthus, and 1.5 MW, fueled with wood chips) were characterized for different operational conditions, and compared to previously obtained results for household wood and pellet stoves. SO2 and NOx emission factors (reported in mg MJFuel-1) were found to not only depend on fuel sulfur/nitrogen content, but also on combustion appliance type and efficiency. Emission factors of SO2, NOx, and PM (particulate matter) increased with increasing load. Particle chemical composition did not primarily depend on operational conditions, but varied mostly with combustion appliances, fuel types, and flue gas cleaning technologies. Black carbon content was decreasing with increasing combustion efficiency; chloride content was strongly enhanced when burning miscanthus. Flue gas cleaning using an electrostatic precipitator caused strong reduction not only in total PM, but also in the fraction of refractory and semi-refractory material within emitted PM1. For the impact of facilities on their surroundings (immissions) not only their total emissions are decisive, but also their stack heights. In immission measurements downwind of the two facilities, a plume could only be observed for the 400 kW facility with low (11 m) stack height (1.5 MW facility: 30 m), and measured immissions agreed reasonably well with predicted ones. The impact of these immissions is non-negligible: At a distance of 50 m from the facility, apart from CO2, also plume contributions of NOx, ultrafine particles, PM1, PM10, poly-aromatic hydrocarbons, and sulfate were detected, with enhancements above background values of 2-130%.

Burn wound conversion describes the process by which superficial partial thickness burns convert into deeper burns necessitating surgical intervention. Fully understanding and thus controlling this phenomenon continues to defy burn surgeons. However, potentially guiding burn wound progression so as to obviate the need for surgery while still bringing about healing with limited scarring is the major unmet challenge. Comprehending the pathophysiologic background contributing to deeper progression of these burns is an essential prerequisite to planning any intervention. In this study, a review of articles examining burn wound progression over the last five years was conducted to analyze trends in recent burn progression research, determine changes in understanding of the pathogenesis of burn conversion, and subsequently examine the direction for future research in developing therapies. The majority of recent research focuses on applying therapies from other disease processes to common underlying pathogenic mechanisms in burn conversion. While ischemia, inflammation, and free oxygen radicals continue to demonstrate a critical role in secondary necrosis, novel mechanisms such as autophagy have also been shown to contribute affect significantly burn progression significantly. Further research will have to determine whether multiple mechanisms should be targeted when developing clinical therapies. PMID:26787127

Census predictions for Florida suggest a 3-fold increase in the 65 and older population within 20 years. We predict resource utilization for burn patients in this age group. Using the Florida Agency for Healthcare Administration admission dataset, we evaluated the effect of age on length of stay, hospital charges, and discharge disposition while adjusting for clinical and demographic factors. Using US Census Bureau data and burn incidence rates from this dataset, we estimated future resource use. Elderly patients were discharged to home less often and were discharged to short-term general hospitals, intermediate-care facilities, and skilled nursing facilities more often than the other age groups (P < .05). They also required home health care and intravenous medications significantly more often (P < .05). Their length of stay was longer, and total hospital charges were greater (P < .05) after adjusting for sex, race, Charleson comorbidity index, payer, total body surface area burned, and burn center treatment. Our data show an age-dependent increase in the use of posthospitalization resources, the length of stay, and the total charges for elderly burn patients. Copyright © 2013 Elsevier Inc.

2014-01-01

Burn injury is a severe form of trauma affecting more than two million people in North America each year. Burn trauma is not a single pathophysiological event but a devastating injury that causes structural and functional deficits in numerous organ systems. Due to its complexity and the involvement of multiple organs, in vitro experiments cannot capture this complexity nor address the pathophysiology. In the past two decades, a number of burn animal models have been developed to replicate the various aspects of burn injury; to elucidate the pathophysiology and explore potential treatment interventions. Understanding the advantages and limitations of these animal models is essential for the design and development of treatments that are clinically relevant to humans. This review paper aims to highlight the common animal models of burn injury in order to provide investigators with a better understanding of the benefits and limitations of these models for translational applications. While many animal models of burn exist, we limit our discussion to the skin healing of mouse, rat, and pig. Additionally, we briefly explain hypermetabolic characteristics of burn injury and the animal model utilized to study this phenomena. Finally, we discuss the economic costs associated with each of these models in order to guide decisions of choosing the appropriate animal model for burn research. PMID:24714880

Burn injury can be debilitating and affect survivors' quality of life in a profound fashion. Burn injury may also lead to serious psychosocial challenges that have not been adequately studied and addressed. Specifically, there has been limited research into the associations of burn injury on community reintegration based on gender. This work analyzed data from 601 burn survivors who completed field testing of a new measure of social participation for burn survivors, the Life Impact Burn Recovery Evaluation (LIBRE) Profile. Differences in item responses between men and women were examined. Scores on the six LIBRE Profile scales were then compared between men and women using analysis of variance and adjusted linear multivariate regression modeling. Overall, men scored significantly better than women on four of the six LIBRE Profile scales: Sexual Relationships, Social Interactions, Work & Employment, and Romantic Relationships. Differences were not substantially reduced after adjustment for demographic characteristics and burn size. Men scored better than women in most of the areas measured by the LIBRE Profile. These gender differences are potentially important for managing burn patients during the post-injury recovery period.

The burn center has 3 separate components: patient rooms, patient support facilities, and staff support facilities. Thirteen rooms are used to care for 16 patients. Two of the 13 rooms are accessible to people with disabilities. These 2 rooms have wide doors that permit a wheelchair to pass through, and they have enough clear floor space for a wheelchair to make a 180 degrees turn. The rooms have a sink that is accessible from a wheelchair. The bathrooms have large, clear floor spaces that allow for the turning of a wheelchair, elevated toilets, grab bars, and showers that permit wheelchair access. Special wheelchairs that provide easier shower and commode access are available. The patient support services feature a large hydrotherapy room that contains a table-shower system that allows a person in a wheelchair to gain access to both sides of the shower table. A tub room has been constructed to provide compact patient bathing and hydromassage, and it is also accessible to people in wheelchairs. The staff support services include a locker room that has a shower accessible to people with disabilities so that staff members with mobility disorders can work in the burn center. Grade II braille writing marks all of the signs that designate the permanent rooms and spacing in the burn center and in the contiguous common use areas. The common use area has a restroom accessible to people with disabilities and a waiting room with a telephone communications system for people with mobility disorders or mobility impairment.

Exploring social and infrastructural factors affecting open burning of municipal solid waste (MSW) in Indian cities: A comparative case study of three neighborhoods of Delhi.

Open municipal solid waste (MSW)-burning is a major source of particulate matter emissions in developing world cities. Despite a legal ban, MSW-burning is observed ubiquitously in Indian cities with little being known about the factors shaping it. This study seeks to uncover social and infrastructural factors that affect MSW-burning at the neighborhood level. We couple physical assessments of the infrastructure provision and the MSW-burning incidences in three different neighborhoods of varying socio-economic status in Delhi, with an accompanying study of the social actors (interviews of waste handlers and households) to explore the extent to which, and potential reasons why, MSW-burning occurs. The observed differences in MSW-burning incidences range from 130 km -2  day -1 in low-income to 30 km -2  day -1 in the high-income areas. However, two high-income areas neighborhoods with functional infrastructure service also showed statistical differences in MSW-burning incidences. Our interviews revealed that, while the waste handlers were aware of the health risks associated with MSW-burning, it was not a high priority in the context of the other difficulties they faced. The awareness of the legal ban on MSW-burning was low among both waste handlers and households. In addition to providing infrastructure for waste pickup, informal restrictions from residents and neighborhood associations can play a significant role in restricting MSW-burning at the neighborhood scale. A more efficient management of MSW requires a combined effort that involves interplay of both social and infrastructural systems. © The Author(s) 2016.

Sensitivity of spectral reflectance values to different burn and vegetation ratios: A multi-scale approach applied in a fire affected area

Pleniou, Magdalini; Koutsias, Nikos

2013-05-01

The aim of our study was to explore the spectral properties of fire-scorched (burned) and non fire-scorched (vegetation) areas, as well as areas with different burn/vegetation ratios, using a multisource multiresolution satellite data set. A case study was undertaken following a very destructive wildfire that occurred in Parnitha, Greece, July 2007, for which we acquired satellite images from LANDSAT, ASTER, and IKONOS. Additionally, we created spatially degraded satellite data over a range of coarser resolutions using resampling techniques. The panchromatic (1 m) and multispectral component (4 m) of IKONOS were merged using the Gram-Schmidt spectral sharpening method. This very high-resolution imagery served as the basis to estimate the cover percentage of burned areas, bare land and vegetation at pixel level, by applying the maximum likelihood classification algorithm. Finally, multiple linear regression models were fit to estimate each land-cover fraction as a function of surface reflectance values of the original and the spatially degraded satellite images. The main findings of our research were: (a) the Near Infrared (NIR) and Short-wave Infrared (SWIR) are the most important channels to estimate the percentage of burned area, whereas the NIR and red channels are the most important to estimate the percentage of vegetation in fire-affected areas; (b) when the bi-spectral space consists only of NIR and SWIR, then the NIR ground reflectance value plays a more significant role in estimating the percent of burned areas, and the SWIR appears to be more important in estimating the percent of vegetation; and (c) semi-burned areas comprising 45-55% burned area and 45-55% vegetation are spectrally closer to burned areas in the NIR channel, whereas those areas are spectrally closer to vegetation in the SWIR channel. These findings, at least partially, are attributed to the fact that: (i) completely burned pixels present low variance in the NIR and high variance in the

Like many other Western burn services, the proportion of major to minor burns managed at Royal Perth Hospital (RPH) is in the order of 1:10. The Burn Specific Health Scale-Brief (BSHS-B) is an established measure of recovery after major burn, however its performance and validity in a population with a high volume of minor burns is uncertain. Utilizing the tool across burns of all sizes would be useful in service wide clinical practice. This study was designed to examine the reliability and validity of the BSHS-B across a sample of mostly minor burn patients. BSHS-B scores of patients, obtained between January 2006 and February 2013 and stored on a secure hospital database were collated and analyzed Cronbach's alpha, factor analysis, logistic regression and longitudinal regression were used to examine reliability and validity of the BSHS-B. Data from 927 burn patients (2031 surveys) with a mean % total burn surface area (TBSA) of 6.7 (SD 10.0) were available for analysis. The BSHS-B demonstrated excellent reliability with a Cronbach's alpha of 0.95. First and second order factor analyses reduced the 40 item scale to four domains: Work; Affect and Relations; Physical Function; Skin Involvement, as per the established construct. TBSA, length of stay and burn surgery all predicted burn specific health in the first three months of injury (p<0.001, p<0.001, p=0.03). BSHS-B whole scale and domain scores showed significant improvement over 24 months from burn (p<0.001). The results from this study show that the structure and performance of the BSHS-B in a burn population consisting of 90% minor burns is consistent with that demonstrated in major burns. The BSHS-B can be employed to track and predict recovery after burns of all sizes to assist the provision of targeted burn care. Crown Copyright © 2013. Published by Elsevier Ltd.

Bacteriophages could be used along with burn wound care products to enhance antimicrobial pressure during treatment. However, some of the components of the topical antimicrobials that are traditionally used for the prevention and treatment of burn wound infection might affect the activity of phages. Therefore, it is imperative to determine the counteraction of therapeutic phage preparations by burn wound care products before application in patients. Five phages, representatives of two morphological families (Myoviridae and Podoviridae) and active against 3 common bacterial burn wound pathogens (Acinetobacter baumannii, Pseudomonas aeruginosa and Staphylococcus aureus) were tested against 13 different products commonly used in the treatment of burn wounds. The inactivation of the phages was quite variable for different phages and different products. Majority of the anti-infective products affected phage activity negatively either immediately or in the course of time, although impact was not always significant. Products with high acidity had the most adverse effect on phages. Our findings demonstrate that during combined treatment the choice of phages and wound care products must be carefully defined in advance. PMID:28750102

Burning mouth syndrome

Burning mouth syndrome (BMS) is a complex disorder that is characterized by warm or burning sensation in the oral mucosa without changes on physical examination. It occurs more commonly in middle-aged and elderly women and often affects the tip of the tongue, lateral borders, lips, hard and soft palate. This condition is probably of multi-factorial origin, often idiopathic, and its etiopathogensis is unknown. BMS can be classified into two clinical forms namely primary and secondary BMS. As a result, a multidisciplinary approach is required for better control of the symptoms. In addition, psychotherapy and behavioral feedback may also help eliminate the BMS symptoms. PMID:26015707

Burns are a challenge for trauma care and a contribution to the surgical burden. The former Soviet republic of Ukraine has a foundation for burn care; however data concerning burns in Ukraine has historically been scant. The objective of this paper was to compare a new burn database to identify problems and implement improvements in burn care and prevention in this country. Retrospective analyses of demographic and clinical data of burn patients including Tukey's post hoc test, analysis of variance, and chi square analyses, and Fisher's exact test were used. Data were compared to the American Burn Association (ABA) burn repository. This study included 1752 thermally injured patients treated in 20 hospitals including Specialized Burn Unit in Municipal Hospital #8 Lviv, Lviv province in Ukraine. Scald burns were the primary etiology of burns injuries (70%) and burns were more common among children less than five years of age (34%). Length of stay, mechanical ventilation use, infection rates, and morbidity increased with greater burn size. Mortality was significantly related to burn size, inhalation injury, age, and length of stay. Wound infections were associated with burn size and older age. Compared to ABA data, Ukrainian patients had double the length of stay and a higher rate of wound infections (16% vs. 2.4%). We created one of the first burn databases from a region of the former Soviet Union in an effort to bring attention to burn injury and improve burn care. Copyright © 2013 Elsevier Ltd and ISBI.

Early excision and skin grafting is the principle treatment for a burned hand although there are occasions when it cannot be done such as severe general condition, delayed consultation, and the lack of a definitive assessment of burn depth. This study analyzes the factors that affected function after a delayed excision and skin graft for hands with a deep dermal burn. This study retrospectively evaluated 43 burned hands that required a delayed excision and split-thickness skin graft on the dorsal side. Cases were required to only have split-thickness skin grafting from the dorsum of the hand and fingers distally to at least the proximal interphalangeal joint at least 8 days after the injury. The hands were divided into two functional categories: Functional category A, normal or nearly normal joint movements, and functional category B, abnormal joint movements. Demographic data were assessed statistically by a univariate analysis following a multiple regression analysis by a stepwise selection. A significant difference was observed between the groups in the number of days from grafting to complete wound healing of the graft site and with or without an escharotomy in the analysis. These parameters were statistically significant predictors of functional category B. The functional outcome of a burned hand after a delayed excision and split-thickness skin graft on the dorsal side became degraded depending on the number of days from grafting to complete wound healing. Cases that underwent an escharotomy also showed deterioration in function.

Burning mouth syndrome: an enigmatic disorder.

PubMed

Javali, M A

2013-01-01

Burning mouth syndrome (BMS) is a chronic oral pain or burning sensation affecting the oral mucosa, often unaccompanied by mucosal lesions or other evident clinical signs. It is observed principally in middle-aged patients and postmenopausal women and may be accompanied by xerostomia and altered taste. Burning mouth syndrome is characterized by an intense burning or stinging sensation, preferably on the tongue or in other areas of mouth. This disorder is one of the most common, encountered in the clinical practice. This condition is probably of multifactorial origin; however the exact underlying etiology remains uncertain. This article discusses several aspects of BMS, updates current knowledge about the etiopathogenesis and describes the clinical features as well as the diagnosis and management of BMS patients.

Rare species can play important functional roles, but human-induced changes to disturbance regimes, such as fire, can inadvertently affect these species. We examined the influence of prescribed burns on the recruitment and diversity of plant species within a temperate forest in southeastern Australia, with a focus on species that were rare prior to burning. Floristic composition was compared among plots in landscapes before and after treatment with prescribed burns differing in the extent of area burnt and season of burn (before-after, control-impact design). Floristic surveys were conducted before burns, at the end of a decade of drought, and 3 years postburn. We quantified the effect of prescribed burns on species grouped by their frequency within the landscape before burning (common, less common, and rare) and their life-form attributes (woody perennials, perennial herbs or geophytes, and annual herbs). Burn treatment influenced the response of rare species. In spring-burn plots, the recruitment of rare annual herbs was promoted, differentiating this treatment from both autumn-burn and unburnt plots. In autumn-burn plots, richness of rare species increased across all life-form groups, although composition remained statistically similar to control plots. Richness of rare woody perennials increased in control plots. For all other life-form and frequency groups, the floristic composition of landscapes changed between survey years, but there was no effect of burn treatment, suggesting a likely effect of rainfall on species recruitment. A prescribed burn can increase the occurrence of rare species in a landscape, but burn characteristics can affect the promotion of different life-form groups and thus affect functional diversity. Drought-breaking rain likely had an overarching effect on floristic composition during our study, highlighting that weather can play a greater role in influencing recruitment and diversity in plant communities than a prescribed burn.

Burn injuries have been more prevalent among low socioeconomic populations and in less developed regions. Incredible advances in burn care and social development over the recent decades, however, should have placed the incidence and severity of burns in a downwards trend. The aim of this review was to give an overview on current trends in burn epidemiology across the world. Also the socioeconomic development in countries that have published epidemiological data used in this study has been taken into account when comparing the results. There was a worldwide downwards trend of burn incidence, burn severity, length of hospital stay, and mortality rate. These findings were particularly pronounced in very highly developed countries. Data from highly and medium developed countries were more heterogeneous. No studies could be obtained from low developed countries. Comparisons between the different studies were compromised by the fact that studies emerged from specialized facilities on one hand and general hospitals on the other. Analyzed studies were also frequently focusing on limited patient populations such as “children” or “elderly”. Our findings indicate the need for an international burn database with a minimal data-set in order to obtain objective and comparable results in respect of burn epidemiology. PMID:27600982

1989-01-01

Among acute "traumatisms", occupational and domestic accidents chiefly share burn. To compare these two causes of severe burns, we examined clinical records of patients hospitalized from January 1986 to February 1989 in the "Grand Burns Center" at the C.T.O. hospital in Turin. Data exclusively refer to patients over 12 years old. 61 out of 313 cases (19%) were due to occupational burns, 221 (71%) to domestic ones (left cases including burns occurred in different surroundings). Males predominance was very high (95%) in the occupational settings, lower though still relevant (60%) in the domestic ones. The topographic distribution of the burns did not show any relevant difference. Similarly, the two groups did not differ as the affected percent of the body surface area (BSA) is concerned: in both cases burns extended cases. Decreased patients were fairly more numerous among the domestic burns (33%) as compared to the occupational ones (18%). The overwhelming majority (90.5%) of domestic burns were caused by fire; such a predominance, though present, was lower (68.8%) among occupational accidents. More in detail, domestic burns were caused as follows: alcohol spraying to stir a fire (26%), gas burst (25%), flammable substances exposed to heat sources (18%), hot water or different liquid (8%), fall over heating devices (6%), fires from cigarettes in bed (5%), kitchen stoves (with or without clothing fire) (5%), brushwood burning (4%), other (3%). It is worth noting that in as many as 40% of the cases of domestic burns patients were affected by a pre-existing neuro-psychic disorder, namely: personality disorders (15%), psychiatric disorders (%), epilepsy (9%), mental debility (7%).

Background Census predictions for Florida suggest a threefold increase in the population 65 or older within 20 years. We predict resource utilization for this age group. Methods Using the Florida Agency for Healthcare Administration admission dataset we evaluated the effect of age on length of stay, hospital charges and discharge disposition while adjusting for clinical and demographic factors. Using U.S. Census Bureau data and burn incidence rates from this dataset we estimated future resource utilization. Results Elderly patients were discharged to home less often and were discharged to short term general hospitals, intermediate care facilities and skilled nursing facilities more often than the other age groups (p < 0.05). They also required home health care and IV medications significantly more often (p <0.05). Their length of stay was longer and total hospital charges were greater (p < 0.05) after adjusting for gender, race, Charleson comorbidity index, payer, TBSA burned and burn center treatment. Conclusions Our data show an age dependent increase in the utilization of post-hospitalization resources, LOS and total charges for elderly burn patients. PMID:23017253

To analyze potential cognitive impairment in patients with burn injury in the inpatient rehabilitation population. Rehabilitation patients with burn injury were compared with the following impairment groups: spinal cord injury, amputation, polytrauma and multiple fractures, and hip replacement. Differences between the groups were calculated for each cognitive subscale item and total cognitive FIM. Patients with burn injury were compared with the other groups using a bivariate linear regression model. A multivariable linear regression model was used to determine whether differences in cognition existed after adjusting for covariates (eg, sociodemographic factors, facility factors, medical complications) based on previous studies. Inpatient rehabilitation facilities. Data from Uniform Data System for Medical Rehabilitation from 2002 to 2011 for adults with burn injury (N=5347) were compared with other rehabilitation populations (N=668,816). Not applicable. Comparison of total cognitive FIM scores and subscales (memory, verbal comprehension, verbal expression, social interaction, problem solving) for patients with burn injury versus other rehabilitation populations. Adults with burn injuries had an average total cognitive FIM score ± SD of 26.8±7.0 compared with an average FIM score ± SD of 28.7±6.0 for the other groups combined (P<.001). The subscale with the greatest difference between those with burn injury and the other groups was memory (5.1±1.7 compared with 5.6±1.5, P<.001). These differences persisted after adjustment for covariates. Adults with burn injury have worse cognitive FIM scores than other rehabilitation populations. Future research is needed to determine the impact of this comorbidity on patient outcomes and potential interventions for these deficits.

Burn prevention has been identified by the World Health Organization (WHO) as a topic in need of further investigation and education throughout the world, with an increased need in low-income countries. It has been noted that implementing educational programs for prevention in high income countries has aided in lowering the rate of burn injuries. The purpose of this study is to evaluate the current education level of knowledge of prevention and first aid treatment of scald burns. A prevention campaign will target these educational needs as a part of an outreach program to improve burn care in Ukraine. The research team evaluated the current health structure in Ukraine and how it could benefit from the increased knowledge of burn prevention and first aid. A test was designed to assess the baseline level of knowledge with regard to first aid and scald prevention in parents, pregnant woman, and healthcare and daycare providers. A total of 14,456 tests were sent to pediatric clinics, obstetrician clinics, and daycare facilities to test respondents. A total of 6,120 completed tests were returned. Doctors presented with the highest level of knowledge averaging 77.0% on prevention and 67.5% on first aid while daycare workers presented the largest gap in knowledge at 65.0% in prevention and 54.3% in first aid. Interest in further educational materials was reported by 92% of respondents. The results of this study clearly show a lack of knowledge in first aid and prevention of scald burn injury in all the populations tested.

To assess outcome differences between locally burned civilians and military personnel burned in a distant combat zone treated in the same facility. The United States Army Institute of Surgical Research (USAISR) Burn Center serves as a referral center for civilians and is the sole center for significant burns in military personnel. We made the hypothesis that outcomes for military personnel burned in the current conflict in Iraq and Afghanistan would be poorer because of delays to definitive treatment, other associated injury, and distance of evacuation. We reviewed the civilian and military records of patients treated at the USAISR from the outset of hostilities in Iraq in April 2003 to May 2005. Demographics, injury data, mortality, and clinical outcomes were compared. : We cared for 751 patients during this time period, 273 of whom were military (36%). Military injuries occurred in a younger population (41 +/- 19 vs. 26 +/- 7 years for civilian and military respectively, P < 0.0001) with a longer time from injury to burn center arrival (1 +/- 5 days vs. 6 +/- 5, P < 0.0001), a higher Injury Severity Score (ISS 5 +/- 8 vs. 9 +/- 11, P < 0.0001), and a higher incidence of inhalation injury (8% vs. 13%, P = 0.024). Total burn size did not differ. Mortality was 7.1% in the civilian and 3.8% in the military group (P = 0.076). When civilians outside the age range of the military cohort were excluded, civilian mortality was 5.0%, which did not differ from the military group (P = 0.57). Total body surface area (TBSA) burned, age > or =40 years, presence of inhalation injury, and ventilator days were found to be important predictors of mortality by stepwise regression, and were used in a final predictive model with the area under receiver operator characteristic curve of 0.97 for both populations considered together. No significant effect of either group was identified during development. Mortality does not differ between civilians evacuated locally and military personnel

Research into nursing home transitions has given limited attention to the facility or community contexts. To identify facility and market factors affecting transitions of nursing home residents back to the community. Multilevel models were used to estimate effects of facility and market factors on facility-level community discharge rates after controlling for resident demographic, health, and functional conditions. Facility discharge rates were adjusted using Empirical Bayes estimation. Annual cohort of first-time admissions (N=24,648) to 378 Minnesota nursing facilities in 75 nursing home markets from July 2005 to June 2006. Community discharge within 90 days of admission; facility occupancy, payer mix, ownership, case-mix acuity, size, admissions from hospitals, nurse staffing level, and proportion of admissions preferring or having support to return to the community; and nursing market population size, average occupancy, market concentration, and availability of home and community-based services. Rates of community discharge (Empirical Bayes residual) were highest in facilities with more residents preferring community discharge, more Medicare days, higher nurse staffing levels, and higher occupancy. In addition, facilities had higher community discharge rates if they were located in markets with a greater ratio of home and community-based services recipients to nursing home residents and with larger populations. State Medicaid programs should undertake system-level interventions that encourage nursing facilities to reduce unused bed capacity, balance the mix of payers, invest in nurse staffing, and take other steps to promote community discharges. In addition, states should increase home and community-based services, particularly in markets with low community discharge rates.

Summary The epidemiological pattern and risk factors of burns and burn infections varies widely in different parts of the world. This study aims to determine the epidemiologic pattern of burn injuries and possible risk factors associated with burn infections in burn units of Gaza strip hospitals. A total of 118 patients were included in the study. The data collected included: patient age and gender, the causes, site, degree, and TBSA of the burns, as well as surgical operations, length of hospital stay, and microbiological profile of samples collected from patients, the environment, and from health care staff. Pediatric and adult patients accounted for 72% and 28% respectively. 58.5% of all patients were male and 41.5% were female. The most common etiological factors in children were scalding, while in adults these were open fire and flammable liquids. The mean TBSA was 12% with a range from 1–90%. Second and third degree burns accounted for 78% and 22% respectively. The area of the body most often affected was the torso (39%), followed by the lower limb (29.7%), and upper limb (17.8%). The predominant microorganisms isolated from burn wounds were Pseudomonas aeruginosa, Enterobacter spp. and Staphylococcus spp. The study showed the highest risk groups to be children and males, and enabled us to identify possible risk factors that can help in future efforts toward prevention and minimizing nosocomial infections in burn units of Gaza strip hospitals.

Estimating the level of alpha heating and determining the onset of the burning plasma regime is essential to finding the path towards thermonuclear ignition. In a burning plasma, the alpha heating exceeds the external input energy to the plasma. Using a simple model of the implosion, it is shown that a general relation can be derived, connecting the burning plasma regime to the yield enhancement due to alpha heating and to experimentally measurable parameters such as the Lawson ignition parameter. A general alpha-heating curve is found, independent of the target and suitable to assess the performance of all laser fusion experiments whether direct or indirect drive. The onset of the burning plasma regime inside the hot spot of current implosions on the National Ignition Facility requires a fusion yield of about 50 kJ.

Health-related quality of life (HRQoL) is reduced after a burn, and is affected by coexisting conditions. The aims of the investigation were to examine and describe effects of coexisting disease on HRQoL, and to quantify the proportion of burned people whose HRQoL was below that of a reference group matched for age, gender, and coexisting conditions. A nationwide study covering 9 years and examined HRQoL 12 and 24 months after the burn with the SF-36 questionnaire. The reference group was from the referral area of one of the hospitals. The HRQoL of the burned patients was below that of the reference group mainly in the mental dimensions, and only single patients were affected in the physical dimensions. The factor that significantly affected most HRQoL dimensions (n=6) after the burn was unemployment, whereas only smaller effects could be attributed directly to the burn. Poor HRQoL was recorded for only a small number of patients, and the decline were mostly in the mental dimensions when compared with a group adjusted for age, gender, and coexisting conditions. Factors other than the burn itself, such as mainly unemployment and pre-existing disease, were most important for the long term HRQoL experience in these patients.

The aim of this study was to know the epidemiology of burns in teenagers. Burn patients over 11 years old admitted in our Institution in the last 10 years were included. Etiology, burn size, hospital stay, quirurgical interventions and long term sequelae were registered. One thousand and eight patients were admitted, 89 were over 11 years (8.8%), 70.7% were boys and 29.3% girls. Fire was the principal agent in 58 cases (65.1%), due to fireworks in 13 (22.4%), alcohol in 7 (12%), explosion of flammable containers (spray) in 4 (6.8%) and gasoline in 3 (5.2%). Fireworks injuries and spray explosions affected face and hand in 88% cases. The median hospital stay was 8 days after admission (1 to 90). 83.1% required surgical treatment with mean of 1.8 +/- 1.4 interventions and 21.3% had long-term sequelaes that required at least one surgical intervention. Fire is the main cause of burns in adolescents. Fireworks injuries represented a quarter of that lesions, and highlights paint spray explosions as new causative agents. Considering the high morbidity in this age group, with permanent functional and aesthetic sequelae, prevention campaigns are needed to reduce such accidents.

Summary Burn injuries are a leading cause of morbidity and mortality, with 195,000 deaths annually. This study was conducted to identify the demographics of burn victims and the effect of different variables on the outcome of their injuries. 4016 patients admitted to the Burns Centre, Civil Hospital Karachi from January 2006 to December 2011 were retrospectively analyzed. Demographics, burn injury details and their outcome were recorded in a pre-designed questionnaire. Injuries were categorized as: fire, chemical, scald or electrical. To estimate total body surface area (TBSA) burned in adults, the rule of nines was used. For children and infants, the Lund-Browder chart was employed. SPSS v16.0 software was used for analysis. Frequencies and percentages of all variables, and the measure of central tendencies and dispersion for continuous variables were calculated. Cross tabs were used to assess mortality. Mean age was 28.13 years. More than half of the cases (n=2337, 58.2%) were aged between 16-30 years. Labourers, housewives and students were the most commonly affected groups. Burn injuries by flame/fire and electricity were most common. Most cases were accidental, followed by suicide attempts and homicides. Mean percentage of TBSA affected was 35.49%. Mean duration of hospital stay was 16.45 days. 50.6% of the expired cases were females. The mean age of expired patients was 30.07 while for patients who survived it was 27.01 years. The outcome of burn injuries is related to various demographic factors. Female gender, increasing age, burn injuries following suicide attempts and greater surface area involvement predict poor outcome. PMID:27857643

The objective of this study was to describe a draft response plan for the tiered triage, treatment, or transportation of 400 adult and pediatric victims (50/million population) of a burn disaster for the first 3 to 5 days after injury using regional resources. Review of meeting minutes and the 11 deliverables of the draft response plan was performed. The draft burn disaster response plan developed for NYC recommended: 1) City hospitals or regional burn centers within a 60-mile distance be designated as tiered Burn Disaster Receiving Hospitals (BDRH); 2) these hospitals be divided into a four-tier system, based on clinical resources; and 3) burn care supplies be provided to Tier 3 nonburn centers. Existing burn center referral guidelines were modified into a hierarchical BDRH matrix, which would vector certain patients to local or regional burn centers for initial care until capacity is reached; the remainder would be cared for in nonburn center facilities for up to 3 to 5 days until a city, regional, or national burn bed becomes available. Interfacility triage would be coordinated by a central team. Although recommendations for patient transportation, educational initiatives for prehospital and hospital providers, city-wide, interfacility or interagency communication strategies and coordination at the State or Federal levels were outlined, future initiatives will expound on these issues. An incident resulting in critically injured burn victims exceeding the capacity of local and regional burn center beds may be a reality within any community and warrants a planned response. To address this possibility within New York City, an initial draft of a burn disaster response has been created. A scaleable plan using local, state, regional, or federal health care and governmental institutions was developed.

Electrical burns are among the most devastating trauma inflicted on the human body. These burns have a higher morbidity, length of stay and a much higher risk of amputation than any other type of burn. Electrical burns affect mostly young, working males because they are more frequently the result of a work accident. However, possibly due to the worldwide economic crisis, we are experiencing a new phenomenon: the theft of high-voltage copper wiring.

Menopause is a physiological process typically occurring in the fifth decade of life. One of the most annoying oral symptoms in this age group is the burning mouth syndrome (BMS), which may be defined as an intraoral burning sensation occurring in the absence of identifiable oral lesion or laboratory findings. Pain in burning mouth syndrome may be described as burning, tender, tingling, hot, scalding, and numb sensation in the oral mucosa. Multiple oral sites may be involved, but the anterior two-third part and the tip of tongue are most commonly affected site. There is no definite etiology for BMS other than the precipitating causative factors, and it is still considered idiopathic. Various treatment options like use of benzodiazepine, anti-depressants, analgesics, capsaicin, alpha lipoic acids, and cognitive behavioral therapy are found to be effective, but definite treatment is still unknown. The present article discusses some of the recent concepts of etiopathogenesis of BMS as well as the role of pharmacotherapeutic management in this disorder. PMID:23411996

Aim: This study aimed at identifying risk factors related to pediatric burns mortality in a middle income country such as Ghana. Methods: The data for the three years retrospective study (May 2009 – April 2012) was obtained from the pediatric burn admissions records and patients’ folders of the Reconstructive Plastic Surgery & Burns Unit (RPSBU), Komfo Anokye Teaching Hospital (KATH), Ghana. Data retrieved included: Demographic features, Total Burned Surface Area (TBSA) incurred; Aetiology of burns; Duration of the admission; Outcome of admission; Part of the body affected and Cost incurred. Ethical approval for this study was obtained from the KNUST-SMS/KATH Committee on Human Research, Publications and Ethics. Data analyses were performed with SPSS 17.0 version. Results: Information on 197 patients was completely retrieved for the study. Burns mortality rate for the study was identified to be 21.3% (N=42). The mean age of the 42 dead patients was 3.7±0.3 years, ranging from 0-13 years, while, males (54.8%, N= 23) outnumbered females (45.2%, N=19). The TBSA burned interquartile range was 48%. In terms of etiology of burns Scald (73.8%, N=31) was the commonest cause of injury. Mortality risk factors identified were Age <6 years (P=0.028); Scald especially hot water and soup (P=0.016); TBSA >36% (P=0.028) and Inhalation injury (P=0.040). Conclusion: Age, scald, TBSA and Inhalation Injury were identified as pediatric burns mortality risk factors in a developing country such as Ghana’s RPSBU. These identified factors will serve as a guideline for plastic surgeons and other health professionals practicing in countries such as Ghana. PMID:23875121

Moist exposed burn ointment (MEBO), from China, has been said to revolutionize burn management. Our study was conducted to compare MEBO with conventional management (C) with respect to the rate of wound healing, antibacterial and analgesic effect, and hospital costs. This is a prospective, randomized, controlled clinical trial conducted between 1 March 1997 and 24 October 1998. The trial was conducted in a specialized burn facility located in a tertiary referral hospital in a developed and industrialized island-state in Southeast Asia. We randomly assigned 115 consecutive patients between the ages of 12 and 80 who had partial-thickness thermal burns covering less than 40% of body surface area (BSA) to receive either MEBO or C. Fifty-seven patients were assigned to MEBO and 58 patients to C. The latter group received twice-daily dressing changes; MEBO patients received MEBO every 4 hours. Patients were hospitalized until 75% BSA had healed. BSA was determined by visual inspection and charted on Lund and Browder charts regularly. Wound healing rate, bacterial infection rate, pain score, and hospitalization costs were recorded. The median time to 75% healing was 17.0 and 20.0 days with MEBO and C, respectively (HR = 0.67, 95% CI = 0.41-1.11, P =.11), suggesting similar efficacy between the 2 modalities. Bacterial infection rates were similar between the 2 groups (HR = 1.10, 95% CI = 0.59-2.03, P =.76). MEBO imparted a greater analgesic effect in the first 5 days of therapy and reduced hospital costs by 8%. MEBO is as effective as conventional management but is not the panacea for all burn wounds. The use of MEBO eases the management of face and neck burns and facilitates early institution of occupational therapy in hand burns. It confers better pain relief such that fewer opiates are used during the first 5 days after burn injury.

Summary The aim of this paper is to review the basic principles of triage in mass burns disasters and discuss the experience of the Lagos State University Teaching Hospital (LASUTH), Ikeja, Nigeria, in the December 2006 disaster at Abule-Egba, Lagos, Nigeria. It is hoped that the experience gained will help in the planning for and management of similar disasters in the developing countries with limited facilities. Burn injury has been described as the severest form of trauma and its management is very challenging as it is often accompanied by numerous pathophysiological changes. Successful management requires expert management by well-trained personnel in equipped and dedicated centres. In mass disasters the total number of victims may exceed the capability of the facility and its staff and a system for sorting out the patients and caring for those that will benefit from the facilities available needs to be developed. Other patients will either be sent to other medical facilities for further treatment or discharged after initial care for future follow-up. Documented experiences in the management of mass burns disasters from petroleum pipeline explosions from developing countries are rare. However, petroleum pipeline explosions, especially in the Lagos area of Nigeria, are relatively common. These cases have been associated with a variety of factors. The resulting morbidity and mortality have been high. LASUTH has a dedicated burns centre, which has received and managed many burn patients. Triage is the medical process of screening patients according to their need of treatment and the resources available. The aims and objectives of triage are discussed, its various levels described, and the final goals elaborated. All the burn victims involved in the 2006 disaster were studied, together with the triage carried out at different levels and the consequent sorting of the patients. Standard burns management was carried out. A total of 385 patients sustained burns of

Burn care in South Africa: a micro cosmos of Africa.

Burn injuries in Africa are common with between 300,000 and 17.5 million children under 5 years sustaining burn injuries annually, resulting in a high estimated fatality rate. These burns are largely environmentally conditioned and therefore preventable. The Western Cape Province in South Africa can be regarded as a prototype of paediatric burns seen on the continent, with large numbers, high morbidity and mortality rates and an area inclusive of all factors contributing to this extraordinary burden of injury. Most of the mechanisms to prevent burns are not easily modified due to the restraint of low socio-economic homes, overcrowding, unsafe appliances, multiple and complex daily demands on families and multiple psycho-social stressors. Children <4 years are at highest risk of burns with an average annual rate of 6.0/10,000 child-years. Burn care in South Africa is predominantly emergency driven and variable in terms of organization, clinical management, facilities and staffing. Various treatment strategies were introduced. The management of HIV positive children poses a problem, as well as the conflict of achieving equity of burn care for all children. Without alleviating poverty, developing minimum standards for housing, burn education, safe appliances and legislation, we will not be able to reduce the "curse of poor people" and will continue to treat the consequences.

Promoted Ignition and Burning Tests of Stainless Steel in Flowing and Nonflowing Oxygen

The Industry-Sponsored Metals Combustion Test Program 96-1 was coordinated through Wendell Hull & Associates, Inc. on behalf of several contributing companies, and all design and testing was performed at the NASA White Sands Test Facility. Phase I of this test program studied the threshold pressure for self-sustained burning of various types and sizes of stain less steel rods in nonflowing oxygen, as observed in Standard Test Method for Determining the Combustion Behavior of Metallic Materials in Oxygen-Enriched Atmospheres (ASTM G 124-95). Phase II studied the ignition and propagation of burning of 316L stainless steel rods and pipe in flowing gaseous oxygen. The test sample configurations were chosen to replicate previous promoted ignition and burning tests as well as to represent geometries and cross-sectional thicknesses common in industrial piping applications. The gas pressw'es and velocities for the test matrix were selected to generally compare with CGA G-4.4 guidelines for the use of stain less steel in oxygen service. This paper summarizes the results from the Phase I nonflowing oxygen tests and presents in detail the results of the Phase II flowing oxygen tests. The maximum sample burn-length is shown as a function of test pressure in Phase 1 and also as a function of gas velocity in Phase IT. These results indicate that flowing oxygen, under the given test conditions, significantly affects maximum sample burn length as compared to nonflowing oxygen. Supplementary flowing oxygen test data on stainless steel rods from a follow-up test program are consistent with these results and are presented herein.

The Mediterranean region is highly susceptible to wildfires. On average, about 60,000 fires take place in this region every year, burning on average half a million hectares of forests and natural vegetation. Wildfires cause environmental degradation and affect the lives of thousands of people in the region. In order to minimize the consequences of these catastrophic events, fire managers and national authorities need to have in their disposal accurate and updated spatial information concerning the size of the burned area as well as the burn severity patterns. Mapping burned areas and burn severity patterns is necessary to effectively support the decision-making process in what concerns strategic (long-term) planning with the definition of post-fire actions at European and national scales. Although a comprehensive archive of burnt areas exists at the European Forest Fire Information System, the analysis of the severity of the areas affected by forest fires in the region is not yet available. Fire severity is influenced by many variables, including fuel type, topography and meteorological conditions before and during the fire. The analysis of fire severity is essential to determine the socio-economic impact of forest fires, to assess fire impacts, and to determine the need of post-fire rehabilitation measures. Moreover, fire severity is linked to forest fire emissions and determines the rate of recovery of the vegetation after the fire. Satellite imagery can give important insights about the conditions of the live fuel moisture content and can be used to assess changes on vegetation structure and vitality after forest fires. Fire events occurred in Greece, Portugal and Spain during the fire season of 2009 were recorded and analyzed in a GIS environment. The Normalized Difference Vegetation Index (NDVI), the Enhanced Vegetation Index (EVI) and the Normalized Burn Ratio (NBR) were calculated from 8-days composites MODIS/TERRA imagery from March to October 2009.

To report physical and psychologic outcomes for young adult survivors of pediatric burns. Prospective, correlational study. Acute and rehabilitation pediatric burn care facility. Eighty-three young adult survivors of pediatric burns, who were 18 to 28 years of age, with total body surface area (TBSA) burns of 30% or greater, and were at least 2 years postburn. Not applicable. Physical outcomes were assessed by muscle strength tests, grip and pinch measurements, mobility levels, and self-care (activities of daily living) skills. Psychologic outcomes included behavioral problems, personality disorder, and incidence of psychiatric illness. An individually administered Structured Clinical Interview for Diagnosis, based on the Diagnostic and Statistical Manual of Mental Disorders, 4th Edition, for psychiatric diagnosis, was used to assess mental health, and behavioral problems were assessed with the Young Adult Self-Report. Participants reported educational achievement, employment status, state of transition from family of origin (home) to independent living, and pair bonding. The Short-Form 36-Item Health Survey and the Quality of Life Questionnaire were used to assess each participant's self-reported general health and quality of life. The majority of subjects had physical and psychologic outcomes that were within the normal range when compared with age-mates who had not experienced burns. The areas that were most likely to be impaired involved peripheral strength (wrist and grip). These deficits affected some self-care skills and correlated with TBSA. Standardized diagnostic interviews showed that greater than 50% of subjects qualified for a psychiatric diagnosis, with anxiety disorders as the most frequently occurring diagnosis. There were few significant correlations of the physical measurements or self-care skills with the burn size, psychologic problems, or social outcomes, and none appeared to be clinically important. Most of the people in this sample were

A One-Dimensional Global-Scaling Erosive Burning Model Informed by Blowing Wall Turbulence

Kibbey, Timothy P.

2014-01-01

A derivation of turbulent flow parameters, combined with data from erosive burning test motors and blowing wall tests results in erosive burning model candidates useful in one-dimensional internal ballistics analysis capable of scaling across wide ranges of motor size. The real-time burn rate data comes from three test campaigns of subscale segmented solid rocket motors tested at two facilities. The flow theory admits the important effect of the blowing wall on the turbulent friction coefficient by using blowing wall data to determine the blowing wall friction coefficient. The erosive burning behavior of full-scale motors is now predicted more closely than with other recent models.

Acute and Perioperative Care of the Burn-Injured Patient

2016-01-01

Care of burn-injured patients requires knowledge of the pathophysiologic changes affecting virtually all organs from the onset of injury until wounds are healed. Massive airway and/or lung edema can occur rapidly and unpredictably after burn and/or inhalation injury. Hemodynamics in the early phase of severe burn injury are characterized by a reduction in cardiac output, increased systemic and pulmonary vascular resistance. Approximately 2–5 days after major burn injury, a hyperdynamic and hypermetabolic state develops. Electrical burns result in morbidity much higher than expected based on burn size alone. Formulae for fluid resuscitation should serve only as guideline; fluids should be titrated to physiologic end points. Burn injury is associated basal and procedural pain requiring higher than normal opioid and sedative doses. Operating room concerns for the burn-injured patient include airway abnormalities, impaired lung function, vascular access, deceptively large and rapid blood loss, hypothermia and altered pharmacology.

This study was a component of a broader review to evaluate burn care in South Africa. A prospective audit of 353 children with thermal injuries admitted to the Red Cross War Memorial Children's Hospital in Cape Town was performed during 2012/2013. The audit was based to assess the adherence of initial burn management to the provincial policy guidelines on the clinical management of the burn wound. The community management of each patient prior to admission to a burns centre was assessed for the following: basic demographics, emergency home management, wound cover, analgesia and transport to medical facilities. Their ages ranged from 1 month to 14 years. The average total body surface area [TBSA] was 15% [1-86%]. Most of the injuries were due to hot water accidents [78.5%] followed by flame burns (9%), direct contact and electricity burns. Two hundred and twenty five children [63%] received first aid measures at home, including cooling with water [166] ice [30] and a cooling agent. No cooling was instituted in 130 and 65% of the patient's wounds were cooled for 10 min or less. Eighty percent proceeded to the referral centre or burns unit without their wounds being covered; with only 19 patients having any medical type of dressing available at home. Two hundred and ninety five children [83.6%] received pain medication prior to admission at the burns unit. Of the 316 patients not directly attending the burns unit, 137 received i.v. fluids of which 95 had burns greater than 10% TBSA. None of the patients were in shock on admission and all i.v. lines were functioning. Forty-four children with burns greater than 10% did not receive i.v. fluids. The audit identified six factors that were inadequately addressed during the pre-admission period: first aid, cooling of the wound, early covering of the wound, resuscitation, pain management and transfer. If these could be readdressed, basic burn care would be substantially improved in the study area. Copyright © 2015 Elsevier

After sustaining burn injuries overseas, U.K. Armed Forces personnel are evacuated to the Royal Centre for Defence Medicine. The objective was to review the etiology of U.K. Military burns managed at the center between 2008 and 2013. Analysis will aid provision planning and assist in the prevention of burn injuries for future tours. The International Burn Injury Database database of all U.K. Armed Forces burn injured patients evacuated to the Queen Elizabeth University Hospital Birmingham between 2008 and 2013 were reviewed retrospectively. Analysis included patient demographics, injury mechanism, burn severity, management, and mortality. There were 65 military personnel with burn injuries requiring repatriation to the United Kingdom. Percentage of 78.5 were sustained in Afghanistan. The mean age was 25 (18-46) years. Percentage of 70.8 were considered noncombat burn injuries. Of the noncombat burns, the mechanism of injury most commonly involved burning waste and misuse of fuels and scalds. The mean TBSA for all patients was 6% (0.05-51%). Areas most commonly affected included arms, legs, and face. The length of hospital stay for combat vs noncombat burn injury patients was 10 vs 7 days. There were no fatalities. In conclusion, substantially fewer military personnel sustained combat burns between 2008 and 2013 than in preceding study period (19 vs 79). The number of accidental noncombat burns remained constant. The decrease in combat burns may reflect a relative decrease in military intensity and effective protective equipment and safety measures. Further education may allow for an additional decrease in preventable burn injuries.

Biomass burning a driver for global change

Recent research has identified another biospheric process that has instantaneous and longer term effects on the production of atmospheric gases: biomass burning. Biomass burning includes the burning of the world`s vegetation-forests, savannas. and agricultural lands, to clear the land and change its use. Only in the past decade have researchers realized the important contributions of biomass burning to the global budgets of many radiatively and chemically active gases - carbon dioxide, methane, nitric oxide, tropospheric ozone, methyl chloride - and elemental carbon particulates. International field experiments and satellite data are yielding a clearer understanding of this important global source ofmore » atmospheric gases and particulates. It is seen that in addition to being a significant instantaneous global source of atmospheric gases and particulates, burning enhances the biogenic emissions of nitric oxide and nitrous oxide from the world`s soils. Biomass burning affects the reflectivity and emissivity of the Earth`s surface as well as the hydrological cycle by changing rates of land evaporation and water runoff. For these reasons, it appears that biomass burning is a significant driver of global change. 20 refs., 4 figs., 2 tabs.« less

Objective: To assess outcome differences between locally burned civilians and military personnel burned in a distant combat zone treated in the same facility. Summary Background Data: The United States Army Institute of Surgical Research (USAISR) Burn Center serves as a referral center for civilians and is the sole center for significant burns in military personnel. We made the hypothesis that outcomes for military personnel burned in the current conflict in Iraq and Afghanistan would be poorer because of delays to definitive treatment, other associated injury, and distance of evacuation. Methods: We reviewed the civilian and military records of patients treated at the USAISR from the outset of hostilities in Iraq in April 2003 to May 2005. Demographics, injury data, mortality, and clinical outcomes were compared. Results: We cared for 751 patients during this time period, 273 of whom were military (36%). Military injuries occurred in a younger population (41 ± 19 vs. 26 ± 7 years for civilian and military respectively, P < 0.0001) with a longer time from injury to burn center arrival (1 ± 5 days vs. 6 ± 5, P < 0.0001), a higher Injury Severity Score (ISS 5 ± 8 vs. 9 ± 11, P < 0.0001), and a higher incidence of inhalation injury (8% vs. 13%, P = 0.024). Total burn size did not differ. Mortality was 7.1% in the civilian and 3.8% in the military group (P = 0.076). When civilians outside the age range of the military cohort were excluded, civilian mortality was 5.0%, which did not differ from the military group (P = 0.57). Total body surface area (TBSA) burned, age ≥40 years, presence of inhalation injury, and ventilator days were found to be important predictors of mortality by stepwise regression, and were used in a final predictive model with the area under receiver operator characteristic curve of 0.97 for both populations considered together. No significant effect of either group was identified during development. Conclusions: Mortality does not differ

The depth of burn has been an important factor often overlooked when estimating the total resuscitation fluid needed for early burn care. The goal of this study was to determine the degree to which full-thickness (FT) involvement affected overall 24-hour burn resuscitation volumes. We performed a retrospective review of patients admitted to our burn intensive care unit from December 2007 to April 2013, with significant burns that required resuscitation using our computerized decision support system for burn fluid resuscitation. We defined the degree of FT involvement as FT Index (FTI; percentage of FT injury/percentage of total body surface area (TBSA) burned [%FT / %TBSA]) and compared variables on actual 24-hour fluid resuscitation volumes overall as well as for any given burn size. A total of 203 patients admitted to our burn center during the study period were included in the analysis. Mean age and weight were 47 ± 19 years and 87 ± 18 kg, respectively. Mean %TBSA was 41 ± 20 with a mean %FT of 18 ± 24. As %TBSA, %FT, and FTI increased, so did actual 24-hour fluid resuscitation volumes (mL/kg). However, increase in FTI did not result in increased volume indexed to burn size (mL/kg per %TBSA). This was true even when patients with inhalation injury were excluded. Further investigation revealed that as %TBSA increased, %FT increased nonlinearly (quadratic polynomial) (R = 0.994). Total burn size and FT burn size were both highly correlated with increased 24-hour fluid resuscitation volumes. However, FTI did not correlate with a corresponding increase in resuscitation volumes for any given burn size, even when patients with inhalation injury were excluded. Thus, there are insufficient data to presume that those who receive more volume at any given burn size are likely to be mostly full thickness or vice versa. This was influenced by a relatively low sample size at each 10%TBSA increment and larger burn sizes disproportionately having more FT burns. A more

Bührer, G; Beier, J P; Horch, R E; Arkudas, A

2017-05-01

Treatment of pediatric burn patients is very important because of the sheer frequency of burn wounds and the possible long-term ramifications. Extensive burns need special care and are treated in specialized burn centers. The goal of this work is to present current standards in burn therapy and important innovations in the treatment of burns in children so that the common and small area burn wounds and scalds in pediatric patients in day-to-day dermatological practice can be adequately treated. Analysis of current literature, discussion of reviews, incorporation of current guidelines. Burns in pediatric patients are common. Improvement of survival can be achieved by treatment in burn centers. The assessment of burn depth and area is an important factor for proper treatment. We give an overview for outpatient treatment of partial thickness burns. New methods may result in better long-term outcome. Adequate treatment of burn injuries considering current literature and guidelines improves patient outcome. Rational implementation of new methods is recommended.

Burning mouth syndrome: the role of contact hypersensitivity.

2009-05-01

Burning mouth syndrome is a burning sensation or stinging disorder affecting the oral mucosa in the absence of any clinical signs or mucosal lesions. Some studies have suggested that burning mouth syndrome could be caused by the metals used in dental prostheses, as well as by acrylate monomers, additives and flavouring agents, although others have not found any aetiologic role for hypersensitivity to dental materials. To evaluate the extent and severity of adverse reactions to dental materials in a group of patients with burning mouth syndrome, and investigate the possible role of contact allergy in its pathogenesis. We prospectively studied 124 consecutive patients with burning mouth syndrome (108 males; mean age 57 years, range 41-83), all of whom underwent allergen patch testing between 2004 and 2007. Sixteen patients (13%) showed positive patch test reactions and were classified as having burning mouth syndrome type 3 or secondary burning mouth syndrome (Lamey's and Scala's classifications). Although we did not find any significant association between the patients and positive patch test reactions, it would be advisable to include hypersensitivity to dental components when evaluating patients experiencing intermittent oral burning without any clinical signs.

The psychological aspects of burn injury have been researched in different parts of world producing different outcomes. Therefore objective of this research is to determine the frequency of Anxiety and Depression in burn patients. To assess the socio-demographic distribution of patients developing Anxiety and Depression and to determine the effects of burn related factors on development of Anxiety and Depression. A Case series was conducted at the Department of Burn, Pakistan Ordinance Factory Hospital, Wah Cantt. for a duration of 12 months commencing from June 2007 and concluded in May 2008. The study population comprised of hospitalized patients with 1% to 50%, selected through non probable sampling technique who were assessed for Anxiety and Depression on fifteen day after burn injury. Testing protocol comprised of questionnaire having socio-demographic variables and burn related variables. Beck Depression Inventory and Beck Anxiety Inventory was applied to evaluate Anxiety and Depression in Burn patients. Descriptive statistics like mean with Standard Deviation was calculated for age. Frequencies along with percentages were calculated for socio-demographic variables. The frequencies and proportions were also calculated for presence and extent of severity of depression and anxiety in burn patients. Fifty patients were included in the study, thirty patients (60%) were male and 20 (40%) were females. The mean age of participants was 33.64 +/- 19 years. Majority of participants, 38 (76%) had sustained burn injury up to 25%. Flame was found to be most common agent of burn injuries affecting 19 (38%) patients. Depression was seen amongst 29 (58%) patients. Thirteen (26 %) patients had mild, 7 (14%) had moderate and 9 (18%) had severe Depressive symptoms. Anxiety was seen among 41 (82%) patients, thirteen (26%) patients had mild, 11 (22%) had moderate and 17 (34%) had severe Anxiety symptoms. Anxiety was present in 41 (82%) and Depression was present in 29 (58

Rich-burn, flame-assisted fuel cell, quick-mix, lean-burn (RFQL) combustor and power generation

Micro-tubular flame-assisted fuel cells (mT-FFC) were recently proposed as a modified version of the direct flame fuel cell (DFFC) operating in a dual chamber configuration. In this work, a rich-burn, quick-mix, lean-burn (RQL) combustor is combined with a micro-tubular solid oxide fuel cell (mT-SOFC) stack to create a rich-burn, flame-assisted fuel cell, quick-mix, lean-burn (RFQL) combustor and power generation system. The system is tested for rapid startup and achieves peak power densities after only 35 min of testing. The mT-FFC power density and voltage are affected by changes in the fuel-lean and fuel-rich combustion equivalence ratio. Optimal mT-FFC performance favors high fuel-rich equivalence ratios and a fuel-lean combustion equivalence ratio around 0.80. The electrical efficiency increases by 150% by using an intermediate temperature cathode material and improving the insulation. The RFQL combustor and power generation system achieves rapid startup, a simplified balance of plant and may have applications for reduced NOx formation and combined heat and power.

Summary Electrical burns are among the most devastating trauma inflicted on the human body. These burns have a higher morbidity, length of stay and a much higher risk of amputation than any other type of burn. Electrical burns affect mostly young, working males because they are more frequently the result of a work accident. However, possibly due to the worldwide economic crisis, we are experiencing a new phenomenon: the theft of high-voltage copper wiring. PMID:27857650

Accelerant-related burns and drug abuse: Challenging combination.

Accelerants are flammable substances that may cause explosion when added to existing fires. The relationships between drug abuse and accelerant-related burns are not well elucidated in the literature. Of these burns, a portion is related to drug manufacturing, which have been shown to be associated with increased burn complications. 1) To evaluate the demographics and clinical outcomes of accelerant-related burns in a Provincial Burn Centre. 2) To compare the clinical outcomes with a control group of non-accelerant related burns. 3) To analyze a subgroup of patients with history of drug abuse and drug manufacturing. Retrospective case control study. Patient data associated with accelerant-related burns from 2009 to 2014 were obtained from the British Columbia Burn Registry. These patients were compared with a control group of non-accelerant related burns. Clinical outcomes that were evaluated include inhalational injury, ICU length of stay, ventilator support, surgeries needed, and burn complications. Chi-square test was used to evaluate categorical data and Student's t-test was used to evaluate mean quantitative data with the p value set at 0.05. A logistic regression model was used to evaluate factors affecting burn complications. Accelerant-related burns represented 28.2% of all burn admissions (N=532) from 2009 to 2014. The accelerant group had higher percentage of patients with history of drug abuse and was associated with higher TBSA burns, ventilator support, ICU stay and pneumonia rates compared to the non-accelerant group. Within the accelerant group, there was no difference in clinical outcomes amongst people with or without history of drug abuse. Four cases were associated with methamphetamine manufacturing, all of which underwent ICU stay and ventilator support. Accelerant-related burns cause significant burden to the burn center. A significant proportion of these patients have history of drug abuse. Copyright © 2017 Elsevier Ltd and ISBI. All rights

Climate change has increased the area affected by forest fires each year in boreal North America. Increases in burned area and fire frequency are expected to stimulate boreal carbon losses. However, the impact of wildfires on carbon emissions is also affected by the severity of burning. How climate change influences the severity of biomass burning has proved difficult to assess. Here, we examined the depth of ground-layer combustion in 178 sites dominated by black spruce in Alaska, using data collected from 31 fire events between 1983 and 2005. We show that the depth of burning increased as the fire season progressed when the annual area burned was small. However, deep burning occurred throughout the fire season when the annual area burned was large. Depth of burning increased late in the fire season in upland forests, but not in peatland and permafrost sites. Simulations of wildfire-induced carbon losses from Alaskan black spruce stands over the past 60 years suggest that ground-layer combustion has accelerated regional carbon losses over the past decade, owing to increases in burn area and late-season burning. As a result, soils in these black spruce stands have become a net source of carbon to the atmosphere, with carbon emissions far exceeding decadal uptake.

2012-06-30

Emissions from simulated open burning of used agricultural pesticide containers were sampled for polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDDs/PCDFs), polycyclic aromatic hydrocarbon compounds (PAHs), and particle matter (PM(10) and PM(2.5)). Clean high density polyethylene (HDPE) containers, containers with trace pesticide, and triple-rinsed containers were burned separately in an open combustion facility and their emissions compared. Two common chlorinated pesticides were used: 2,4-dichlorophenoxyacetic acid (2,4-D) and 1-chloro-3-ethylamino-5-isopropylamino-2,4,6-triazine (atrazine). PCDD/PCDF emission factors ranged from 0.1 to 24ng toxic equivalents (TEQ)/kg C burned with a mean and median of 4.9 and 1.9ng TEQ/kgC burned, respectively. In a limited number of trials, the trace 2,4-D in the HDPE container led to a statistically significant increase in PCDD/PCDF formation compare to all other conditions. Residual atrazine did not lead to more PCDD/PCDF than the unrinsed 2,4-D container. Total (16 compounds) PAH emission factors varied from 1.5 to 6.7mg/kgC burned. These limited data suggest that rinsing the 2,4-D container prior to burning reduces both PCDD/PCDF and PAH emissions. Nine PM(2.5) emission factors ranged from 9 to 35mg/gC burned and ten PM(10) values ranged from 6 to 43mg/gC burned. Neither pesticide appeared to have any effect on PM concentration.

Functional Group Analysis of Biomass Burning Particles Using Infrared Spectroscopy

NASA Astrophysics Data System (ADS)

Horrell, K.; Lau, A.; Bond, T.; Iraci, L. T.

2008-12-01

Biomass burning is a significant source of particulate organic carbon in the atmosphere. These particles affect the energy balance of the atmosphere directly by absorbing and scattering solar radiation, and indirectly through their ability to act as cloud condensation nuclei (CCN). The chemical composition of biomass burning particles influences their ability to act as CCN, thus understanding the chemistry of these particles is required for understanding their effects on climate and air quality. As climate change influences the frequency and severity of boreal forest fires, the influence of biomass burning aerosols on the atmosphere may become significantly greater. Only a small portion of the organic carbon (OC) fraction of these particles has been identified at the molecular level, although several studies have explored the general chemical classes found in biomass burning smoke. To complement those studies and provide additional information about the reactive functional groups present, we are developing a method for polarity-based separation of compound classes found in the OC fraction, followed by infrared (IR) spectroscopic analysis of each polarity fraction. It is our goal to find a simple, relatively low-tech method which will provide a moderate chemical understanding of the entire suite of compounds present in the OC fraction of biomass burning particles. Here we present preliminary results from pine and oak samples representative of Midwestern United States forests burned at several different temperatures. Wood type and combustion temperature are both seen to affect the composition of the particles. The latter seems to affect relative contributions of certain functional groups, while oak demonstrates at least one additional chemical class of compounds, particularly at lower burning temperatures, where gradual solid-gas phase reactions can produce relatively large amounts of incompletely oxidized products.

Face burns are a singular pathology with great functional and psychological impact in the patients suffering them. The ears play a fundamental role in personal interactions and damage to this organ results in physical and emotional distress. The reconstructive treatment of the burned ear is a challenge. Multiple procedures have been described to achieve success in the reconstruction of the burned ear; immediate reconstruction with autologous rib cartilage, secondary reconstruction, alloplastic material reconstruction, tissue expansion, skin grafts and also microvascular flaps are some of the most common procedures used in this patients. All these techniques focus on giving a natural appearance to the patient. Burns to the ears affect 30% of the patients with facial burns, they require an excellent treatment given by a multidisciplinary team. Copyright © 2017 Academia Mexicana de Cirugía A.C.

The aims of this study were to determine whether a change occurred in the pattern of assault burn injury cases hospitalised to the adult state burns unit, Western Australia, from 2004 to mid-year of 2012, and to compare patient and burn characteristics of adult assault burns with those admitted for unintentional burns. Study data were obtained from the Royal Perth Hospital (RPH) Burns Minimum Dataset (BMDS). Aggregated data of unintentional burn admissions during the same period were provided by the BMDS data manager to enable comparisons with assault burn patients. Assault burn admissions during 2004-2012 accounted for approximately 1% of all adult burn hospitalisations. All assault victims were burned by either thermal or scald agents. A high rate of intubation (24%) and ICU admission (1 in 3 cases) was observed in the fire assault group. The six assault cases undergoing intubation were severe burns, median TBSA 50%, most commonly affecting the face, head and torso, half of these cases had inhalational injuries and also required escharotomies. Comparison of admissions by calendar period showed no statistically significant differences in demographic, burn cause or TBSA%. However, statistically significant differences were found for pre-morbid psychiatric history (15% vs. 58%, p=0.025) and concomitant fractures or dislocations (46% vs. 2%), p=0.011). While the proportion of assault burn admissions per total burn admissions steadily increased from 0.4% in 2009 to 1.5% in mid-2012, this proportion did not exceed that peak level observed of 2.1% for 2004.

Electrical burns in sports fishing: a case report.

2014-11-01

Electrical burns are among the most devastating types of burns, with wide-ranging injuries. They can sometimes occur in the context of fishing, usually involving high voltages. The authors present the case of a 59-year-old-man who suffered a sports accident during a fishing competition, with the formation of an electrical arc due to proximity of the fishing rod and high voltage cables. He presented burns affecting 3% of TBSA, third degree deep burns on trunk and left hand; no signs of cardiac injury. He was admitted to our Burn Unit for monitoring, care dressing and surgical treatment; complete wound healing was achieved after 24 days. Due to its relatively small share among burns, published data on electrical injuries and fishing remain scarce, and differ in patient collectives due to infrastructural or environmental differences. The authors are not aware of published specific reports on electrical burns in sports fishing practice, like the case here presented. The authors want to alert for potential medical, social and economic consequences of this type of sports accidents that could be entirely avoidable with some preventive measures.

Measuring the thermonuclear burn history is an important way to diagnose inertial fusion implosions. Here, using the gas Cherenkov detectors at the OMEGA laser facility, we measure the HT fusion burn in a H 2+T 2 gas-fueled implosion for the first time. Then, using multiple detectors with varied Cherenkov thresholds, we demonstrate a technique for simultaneously measuring both the HT and DT burn histories from an implosion where the total reaction yields are comparable. This new technique will be used to study material mixing and kinetic phenomena in implosions.

A multi-sensor burned area algorithm for crop residue burning in northwestern India: validation and sources of error

NASA Astrophysics Data System (ADS)

Liu, T.; Marlier, M. E.; Karambelas, A. N.; Jain, M.; DeFries, R. S.

2017-12-01

A leading source of outdoor emissions in northwestern India comes from crop residue burning after the annual monsoon (kharif) and winter (rabi) crop harvests. Agricultural burned area, from which agricultural fire emissions are often derived, can be poorly quantified due to the mismatch between moderate-resolution satellite sensors and the relatively small size and short burn period of the fires. Many previous studies use the Global Fire Emissions Database (GFED), which is based on the Moderate Resolution Imaging Spectroradiometer (MODIS) burned area product MCD64A1, as an outdoor fires emissions dataset. Correction factors with MODIS active fire detections have previously attempted to account for small fires. We present a new burned area classification algorithm that leverages more frequent MODIS observations (500 m x 500 m) with higher spatial resolution Landsat (30 m x 30 m) observations. Our approach is based on two-tailed Normalized Burn Ratio (NBR) thresholds, abbreviated as ModL2T NBR, and results in an estimated 104 ± 55% higher burned area than GFEDv4.1s (version 4, MCD64A1 + small fires correction) in northwestern India during the 2003-2014 winter (October to November) burning seasons. Regional transport of winter fire emissions affect approximately 63 million people downwind. The general increase in burned area (+37% from 2003-2007 to 2008-2014) over the study period also correlates with increased mechanization (+58% in combine harvester usage from 2001-2002 to 2011-2012). Further, we find strong correlation between ModL2T NBR-derived burned area and results of an independent survey (r = 0.68) and previous studies (r = 0.92). Sources of error arise from small median landholding sizes (1-3 ha), heterogeneous spatial distribution of two dominant burning practices (partial and whole field), coarse spatio-temporal satellite resolution, cloud and haze cover, and limited Landsat scene availability. The burned area estimates of this study can be used to build

We deployed the single-particle soot photometer (SP2) to make measurements of biomass burning refractory black carbon (rBC) mass loadings and size distributions to correlate with non-refractory particulate mattermore » (NR-PM; i.e., HR-AMS) and rBC (SP-AMS) measurements as a function of photo-oxidation processes in an environmental chamber. With these measurements, we will address the following scientific questions: 1. What are the emission indices (g/kg fuel) of rBC from various wildland fuels from the Pacific Northwest (i.e., relevant to BBOP analysis) as a function of combustion conditions and simulated atmospheric processing in an environmental chamber? 2. What are the optical properties (e.g., mass-specific absorption cross-section [MAC], single-scattering albedo [SSA], and absorption Angstrom exponent [AAE)] of rBC emitted from various wildland fuels and how are they impacted by atmospheric processing? 3. How does the mixing state of rBC in biomass-burning plumes relate to the optical properties? 4. How does the emitted rBC affect radiative forcing?« less

Characterization of Emissions from Open Burning of Meals ...

EPA Pesticide Factsheets

Emissions from burning current and candidate Meals Ready-to-Eat (MRE) packaging and shipping containers were characterized in an effort to assuage concerns that combustive disposal of waste at forward operating bases could pose an environmental or inhalation threat. Four types of container materials, both box and liners, including the currently used fiberboard, new corrugated fiberboard with Spektrakote polymer, new fiberboard without Spektrakote polymer, and the current fiberboard without wet strength were burned in an open burn test facility that simulated the burn pit disposal methods in Iraq and Afghanistan. MREs, including both current and proposed packaging materials, were added to a single container type to examine their effect on emissions. One quarter of the food was left in the packaging to represent unused meal components. The proposed packaging, consisting of a nano-composite polymer, was added in 25 % increments compared to traditional MRE packaging to create a range of usage levels. Emission factors, mass of pollutant per mass of burned material, were increased over the emission factors of the package containers themselves by the addition of the multi-component MREs, with the exception of Volatile Organic Compounds (VOCs). In general, little distinction was observed when comparing emission factors from the four container materials and when comparing the four MRE compositions. The majority of Particulate Matter (PM) emissions were of particles that

The burn/terror group had a mortality rate of 6.4% which was similar to the no-burn/terror group (6.6%). Terror-attack injuries with accompanying burns have a more complex presentation, are of higher severity, and are associated with increased length of hospital stay and a higher ICU admissions rate, compared with terror-attack injuries without burns and non terror-attack related burns. However, mortality rates in terror-attack injuries are not affected by burns.

Initial therapy of severe burns in specialized burn trauma centers is a challenging task faced by the treating multi-professional and interdisciplinary team. A lack of consistent operating procedures and varying structural conditions was recently demonstrated in preliminary data of our group. These results raised the question on how specific treatment measures in acute burn care are met in the absence of standardized guidelines. A specific questionnaire containing 57 multiple-choice questions was sent to all 22 major burn centers in Germany, Austria and Switzerland. The survey included standards of airway management and ventilation, fluid management and circulation, body temperature monitoring and management, topical burn wound treatment and a microbiological surveillance. Additionally, the distribution of standardized course systems was covered. 17 out of 22 questionnaires (77%) were returned completed. Regarding volume resuscitation, results showed a similar approach in estimating initial fluid while discrepancies persisted in the use of colloidal fluid and human albumin. Elective tracheostomy and the need for bronchoscopy with suspected inhalation injury were the most controversial issues revealed by the survey. Topical treatment of burned body surface also followed different principles regarding the use of synthetic epidermal skin substitutes or enzymatic wound debridement. Less discrepancy was found in basic diagnostic measures, body temperature management, estimation of the extent of burns and microbiological surveillance. While many burn-related issues are clearly not questionable and managed in a similar way in most participating facilities, we were able to show that the most contentious issues in burn trauma management involve initial volume resuscitation, management of inhalation trauma and topical burn wound treatment. Further research is required to address these topics and evaluate a potential superiority of a regime in order to increase the level of

Work-related upper extremity burns often occur. The cause directs the course of action. Thermal burns should be assessed for system alterations, and depth of burn should be determined. Deep partial-thickness burns and more severe burns require a specialist evaluation. Chemical burns must be irrigated and the agent identified. Some chemical burns, such as those that involve phenols and metal fragments, require specific topical applications before water lavage. Hydrofluoric acid burns can cause life-threatening electrolyte abnormalities with a small, highly concentrated acid burn. The goal with any extremity burn is to provide the patient with a multidisciplinary team approach to achieve a functional, usable extremity.

Laser in the management of burn scars.

Burn scars are associated with significant morbidity ranging from contractures, pruritus, and disfigurement to psychosocial impairment. Traditional therapies include silicone gel, compression garments, corticosteroid injections, massage therapy, and surgical procedures, however, newer and advanced therapies for the treatment of burn scars have been developed. Lasers, specifically ablative fractional lasers, show potential for the treatment of burn scars. Both MeSH and keyword searches of the PubMed, Medline and Embase databases were performed and relevant articles were read in full for the compilation of this review. Fifty-one relevant observational studies, clinical trials, and systematic reviews published in English from 2006 to 2016 were reviewed and summarized. Laser therapy is effective for the treatment of burn scar appearance, including measures such as pigmentation, vascularity, pliability, and thickness. Ablative fractional laser therapy, in particular, shows significant potential for the release of contractures allowing for improved range of motion of affected joints. Patients may benefit from the use of lasers in the treatment of burn scars, and the safety profile of lasers allows the benefits of treatment to outweigh the risks. Laser therapy should be included in burn scar treatment protocols as an adjuvant therapy to traditional interventions. Copyright © 2017 Elsevier Ltd and ISBI. All rights reserved.

A Burning Rate Emulator (BRE) for Study in Microgravity

NASA Technical Reports Server (NTRS)

Markan, A.; Sunderland, P. B.; Quintiere, J. G.; DeRis, J.; Stocker, D. P.

2015-01-01

A gas-fueled burner, the Burning Rate Emulator (BRE), is used to emulate condensed-phase fuel flames. The design has been validated to easily measure the burning behavior of condensed-phase fuels by igniting a controlled stream of gas fuel and diluent. Four properties, including the heat of combustion, the heat of gasification, the surface temperature, and the laminar smoke point, are assumed to be sufficient to define the steady burning rate of a condensed-phase fuel. The heat of gasification of the fuel is determined by measuring the heat flux and the fuel flow rate. Microgravity BRE tests in the NASA 5.2 s drop facility have examined the burning of pure methane and ethylene (pure and 50 in N2 balance). Fuel flow rates, chamber oxygen concentration and initial pressure have been varied. Two burner sizes, 25 and 50 mm respectively, are chosen to examine the nature of initial microgravity burning. The tests reveal bubble-like flames that increase within the 5.2s drop but the heat flux received from the flame appears to asymptotically approach steady state. Portions of the methane flames appear to locally detach and extinguish at center, while its shape remains fixed, but growing. The effective heat of gasification is computed from the final measured net heat flux and the fuel flow rate under the assumption of an achieved steady burning. Heat flux (or mass flux) and flame position are compared with stagnant layer burning theory. The analysis offers the prospect of more complete findings from future longer duration ISS experiments.

Can salvage logging affect seed dispersal by birds into burned forests?

The recovery of vegetation in Mediterranean ecosystems after wildfire is mostly a result of direct regeneration, since the same species existing before the fire regenerate on-site by seeding or resprouting. However, the possibility of plant colonization by dispersal of seeds from unburned areas remains poorly studied. We addressed the role of the frugivorous, bird-dependent seed dispersal (seed rain) of fleshy-fruited plants in a burned and managed forest in the second winter after a fire, before on-site fruit production had begun. We also assessed the effect on seed rain of different microhabitats resulting from salvage logging (erosion barriers, standing snags, open areas), as well as the microhabitats of unlogged patches and an unburned control forest, taking account of the importance of perches as seed rain sites. We found considerable seed rain by birds in the burned area. Seeds, mostly from Olive trees Olea europaea and Evergreen pistaches Pistacia lentiscus, belonged to plants fruiting only in surrounding unburned areas. Seed rain was heterogeneous, and depended on microhabitat, with the highest seed density in the unburned control forest but closely followed by the wood piles of erosion barriers. In contrast, very low densities were found under perches of standing snags. Furthermore, frugivorous bird richness seemed to be higher in the erosion barriers than elsewhere. Our results highlight the importance of this specific post-fire management in bird-dependent seed rain and also may suggest a consequent heterogeneous distribution of fleshy-fruited plants in burned and managed areas. However, there needs to be more study of the establishment success of dispersed seeds before an accurate assessment can be made of the role of bird-mediated seed dispersal in post-fire regeneration.

Scarring following full thickness burns leads to significant reductions in range of motion and quality of life for burn patients. To effectively study scar development and the efficacy of anti-scarring treatments in a large animal model (female red Duroc pigs), reproducible, uniform, full-thickness, burn wounds are needed to reduce variability in observed results that occur with burn depth. Prior studies have proposed that initial temperature of the burner, contact time with skin, thermal capacity of burner material, and the amount of pressure applied to the skin need to be strictly controlled to ensure reproducibility. The purpose of this study was to develop a new burner that enables temperature and pressure to be digitally controlled and monitored in real-time throughout burn wound creation and compare it to a standard burn device. A custom burn device was manufactured with an electrically heated burn stylus and a temperature control feedback loop via an electronic microstat. Pressure monitoring was controlled by incorporation of a digital scale into the device, which measured downward force. The standard device was comprised of a heat resistant handle with a long rod connected to the burn stylus, which was heated using a hot plate. To quantify skin surface temperature and internal stylus temperature as a function of contact time, the burners were heated to the target temperature (200±5°C) and pressed into the skin for 40s to create the thermal injuries. Time to reach target temperature and elapsed time between burns were recorded. In addition, each unit was evaluated for reproducibility within and across three independent users by generating burn wounds at contact times spanning from 5 to 40s at a constant pressure and at pressures of 1 or 3lbs with a constant contact time of 40s. Biopsies were collected for histological analysis and burn depth quantification using digital image analysis (ImageJ). The custom burn device maintained both its internal

Burning mouth syndrome (BMS) is characterised by the presence of a burning sensation in the oral mucosa in the absence of any clinically apparent mucosal sign. It occurs more commonly in older women and often affects the tongue tip and lateral borders, lips, and hard and soft palates. Besides the burning sensation, patients with BMS may complain of unremitting oral mucosal pain, dysgeusia, and xerostomia. The exact pathophysiology of primary BMS remains unknown. A major challenge for the clinician is the treatment of BMS: identifying possible causative factors is the first step, but BMS is often idiopathic. Drug therapy, in addition to behavioural therapy and psychotherapy, may help to eliminate the symptoms. Considering the growing incidence of BMS in older people, further research is required to determine the true efficacy of current management strategies for patients with this disorder.

Explanatory Model of Resilience in Pediatric Burn Survivors.

PubMed

Quezada, Lucía; González, Mónica T; Mecott, Gabriel A

2016-01-01

Identifying factors of adjustment in pediatric burn patients may facilitate appropriate mental health interventions postinjury. The aim of this is study was to explore the roles of both the patient's and caregivers' resilience and posttraumatic stress in pediatric burn survivor adjustment. For the purposes of the study, "51 patient-parent/guardian" dyads participated. Patients answered the Resilience Questionnaire for Children and Adolescents, and caregivers answered the Mexican Resilience Scale and the Davidson Trauma Scale. The roles of patient age, time since the burn, and size of burn injury were also considered. Statistical analyses included Spearman's ρ for correlations and structural equation modeling. P less than .05 was considered significant. Patients and caregivers reported high levels of resilience, and the majority of caregivers reported low severity of posttraumatic stress disorder symptoms. Pediatric burn survivors' resilience was associated with being younger at the time of the burn and less severity of intrusive and avoidance symptoms in caregivers; it was also associated with a higher resilience in caregivers. It can be concluded that psychological responses of caregivers of pediatric burn survivors affect the well being and positive adjustment of patients; thus psychological services for caregivers would likely have a double benefit for both caregivers and patients.

Campfire burns in children are a significant health issue. It is imperative that the extent of the problem is examined and strategies discussed to inform future prevention campaigns. A retrospective review of data from the Queensland Paediatric Burns Registry for all children presenting with campfire burns between January 2013 and December 2014 (inclusive). Information collected included patient demographics, detail regarding mechanism of injury, first aid, Total Body Surface Area (TBSA), burn depth, and treatment. Seventy-five children with campfire burns were seen in our paediatric burns centre during this 2-year period. The median age of patients was 3 years (range 10 days-14 years). The hands and feet were the areas most commonly affected. Eleven percent of patients suffered flame burns, whilst 89% suffered contact burns from the hot coals or ashes. Of the latter group, approximately half experienced burns from campfires that had been extinguished for at least one night. Thirteen percent of patients underwent split thickness skin grafting. The incidence of burns was increased during school holiday months. We have previously demonstrated the effectiveness of targeted campaigns in reducing the incidence of campfire burns. A significant portion of patients sustained burns from incorrectly extinguished campfires. These injuries are likely to be preventable with ongoing public awareness campaigns.

Hand burns predominantly affect young adults, and therefore have serious social and financial implications. In the present work, 106 patients with less than 25% body surface area burns and acute partial-thickness burned hands were managed using polyethylene bags and 1% local silver sulphadiazine (SSD) cream or moist exposed burn ointment (MEBO). Females made up 61.3% of the cases and flame burn was the majority cause (54.7%). There were no significant differences between the two groups regarding either the analgesic effect after local ointment application or hand movement inside the polyethylene bag. Local agent crustation over the wound was very evident in the hands managed by local 1% SSD cream (69.81%). On follow-up, the burned hands healed faster using local MEBO (10.48 versus 14.53 days), with fewer post-burn hand deformities and better active hand movements; however, the total cost until complete hand burn wound healing was higher with MEBO than with 1% SSD, although the final results were superior, with early return to work, when MEBO was used. We concluded that the use of MEBO as a topical agent and of polyethylene bags for the dressing of the acute partial-thickness burned hand accelerated healing; daily wound evaluation was easy as there was no crustation over it of the agent. It was more expensive than 1% SSD cream but presented fewer post-burn complications and more rapid healing, with shorter hospital stay.

Introduction The burn wound exudate represents the burn tissue microenvironment. Extracting information from the exudate relating to cellular components, signaling mediators and protein content can provide much needed data relating to the local tissue damage, depth of the wound and probable systemic complications. This review examines the scientific data extracted from burn wound exudates over the years and proposes new investigations that will provide useful information from this underutilized resource. Method A literature review was conducted using the electronic database PubMed to search for literature pertaining to burn wound or blister fluid analysis. Key words included burn exudate, blister fluid, wound exudate, cytokine burn fluid, subeschar fluid, cytokine burns, serum cytokines. 32 relevant article were examined and 29 selected as relevant to the review. 3 papers were discarded due to questionable methodology or conclusions. The reports were assessed for their affect on management decisions and diagnostics. Furthermore, traditional blood level analysis of these mediators was made to compare the accuracy of blood versus exudate in burn wound management. Extrapolations are made for new possibilities of burn wound exudate analysis. Results Studies pertaining to burn wound exudate, subeschar fluid and blister fluid analyses may have contributed to burn wound management decisions particularly related to escharectomies and early burn wound excision. In addition, information from these studies have the potential to impact on areas such as healing, scarring, burn wound conversion and burn wound depth analysis. Conclusion Burn wound exudate analysis has proven useful in burn wound management decisions. It appears to offer a far more accurate reflection of the burn wound pathophysiology than the traditional blood/serum investigations undertaken in the past. New approaches to diagnostics and treatment efficacy assessment are possible utilizing data from this fluid

There are contrasting opinions on the use of prescribed burning management in European grasslands. On the one hand, prescribed burning can be effectively used for the management of open landscapes, controlling dominant species, reducing accumulated litter or decreasing wildfire risk. On the other hand burning can have a detrimental impact on grassland biodiversity by supporting competitor grasses and by threatening several rare and endangered species, especially arthropods. We studied the effects of prescribed burning in alkaline grasslands of high conservation interest. Our aim was to test whether dormant-season prescribed burning can be an alternative conservation measure in these grasslands. We selected six sites in East-Hungary: in three sites, a prescribed fire was applied in November 2011, while three sites remained unburnt. We studied the effects of burning on soil characteristics, plant biomass and on the composition of vegetation and arthropod assemblages (isopods, spiders, ground beetles and rove beetles). Soil pH, organic matter, potassium and phosphorous did not change, but soluble salt content increased significantly in the burnt sites. Prescribed burning had several positive effects from the nature conservation viewpoint. Shannon diversity and the number of flowering shoots were higher, and the cover of the dominant grass Festuca pseudovina was lower in the burnt sites. Graminoid biomass was lower, while total, green and forb biomass were higher in the burnt plots compared to the control. The key finding of our study was that prescribed burning did not decrease the abundance and diversity of arthropod taxa. Species-level analyses showed that out of the most abundant invertebrate species, 10 were not affected, 1 was negatively and 1 was positively affected by burning. Moreover, our results suggest that prescribed burning leaving unburnt patches can be a viable management tool in open landscapes, because it supports plant diversity and does not threaten

Burning mouth syndrome (BMS) is a chronic pain condition. It has been described by the International Headache Society as "an intra-oral burning or dysesthetic sensation, recurring daily for more than 2 h/day for more than 3 months, without clinically evident causative lesions." BMS is frequently seen in women in the peri-menopausal and menopausal age group in an average female/male ratio of 7:1. The site most commonly affected is the anterior two-thirds of the tongue. The patient may also report taste alterations and oral dryness along with the burning. The etiopathogenesis is complex and is not well-comprehended. The more accepted theories point toward a neuropathic etiology, but the gustatory system has also been implicated in this condition. BMS is frequently mismanaged, partly because it is not well-known among healthcare providers. Diagnosis of BMS is made after other local and systemic causes of burning have been ruled out as then; the oral burning is the disease itself. The management of BMS still remains a challenge. Benzodiazepines have been used in clinical practice as the first-line medication in the pharmacological management of BMS. Nonpharmacological management includes cognitive behavioral therapy and complementary and alternative medicine (CAM). The aim of this review is to familiarize healthcare providers with the diagnosis, pathogenesis, and general characteristics of primary BMS while updating them with the current treatment options to better manage this group of patients.

Interactions between family members and characteristics of family life and function may affect a child's recovery from burn injury. We prospectively examined the relationship between family characteristics and physical and psychosocial recovery from burns. The families of 399 burned children aged 5 years to 18 years admitted to one of four Shriners Hospitals for Children for management of acute burns completed the Family Environment Scale within 7 days of admission and then the American Burn Association/Shriners Hospitals for Children Burn Outcome Questionnaire (BOQ) at baseline, 3, 6, 12, 18, 24, 36, and 48 months. Generalized estimating equations with random effects for the time since burn were used to track recovery of the BOQ patient-centered domains associated with baseline family characteristics during the course of the study. The children had a mean age of 11 years and burn size of 32% total body surface area burned. Higher Family Environment Scale scores in cohesion, independence, organization, and active recreational orientation were associated with significantly better rates of recovery in multiple BOQ domains of health-related quality of life. Higher scores in conflict and achievement orientation predicted statistically significant impaired recovery. Higher expressiveness predicted greater difficulty with school reentry. Family characteristics affect the recovery of children after serious burns. Some of these may be amenable to focused anticipatory family interventions to help optimize outcomes. In particular, those characteristics that impair school reentry should be targeted.

Burns education for non-burn specialist clinicians in Western Australia.

PubMed

McWilliams, Tania; Hendricks, Joyce; Twigg, Di; Wood, Fiona

2015-03-01

Burn patients often receive their initial care by non-burn specialist clinicians, with increasingly collaborative burn models of care. The provision of relevant and accessible education for these clinicians is therefore vital for optimal patient care. A two phase design was used. A state-wide survey of multidisciplinary non-burn specialist clinicians throughout Western Australia identified learning needs related to paediatric burn care. A targeted education programme was developed and delivered live via videoconference. Pre-post-test analysis evaluated changes in knowledge as a result of attendance at each education session. Non-burn specialist clinicians identified numerous areas of burn care relevant to their practice. Statistically significant differences between perceived relevance of care and confidence in care provision were reported for aspects of acute burn care. Following attendance at the education sessions, statistically significant increases in knowledge were noted for most areas of acute burn care. Identification of learning needs facilitated the development of a targeted education programme for non-burn specialist clinicians. Increased non-burn specialist clinician knowledge following attendance at most education sessions supports the use of videoconferencing as an acceptable and effective method of delivering burns education in Western Australia.

Tests of Flammability of Cotton Fabrics and Expected Skin Burns in Microgravity

NASA Technical Reports Server (NTRS)

Cavanagh, Jane M.; Torvi, David A.; Gabriel, Kamiel S.; Ruff, Gary A.

2004-01-01

During a shuttle launch and other portions of space flight, astronauts wear specialized flame resistant clothing. However during most of their missions on board the Space Shuttle or International Space Station, astronauts wear ordinary clothing, such as cotton shirts and pants. As the behaviour of flames is considerably different in microgravity than under earth's gravity, fabrics are expected to burn in a different fashion in microgravity than when tested on earth. There is interest in determining how this change in burning behaviour may affect times to second and third degree burn of human skin, and how the results of standard fabric flammability tests conducted under earth's gravity correlate with the expected fire behaviour of textiles in microgravity. A new experimental apparatus was developed to fit into the Spacecraft Fire Safety Facility (SFSF), which is used on NASA's KC-135 low gravity aircraft. The new apparatus was designed to be similar to the apparatus used in standard vertical flammability tests of fabrics. However, rather than using a laboratory burner, the apparatus uses a hot wire system to ignite 200 mm high by 80 mm wide fabric specimens. Fabric temperatures are measured using thermocouples and/or an infrared imaging system, while flame spread rates are measured using real time observations or video. Heat flux gauges are placed between 7 and 13 mm away from the fabric specimen, so that heat fluxes from the burning fabric to the skin can be estimated, along with predicted times required to produce skin burns. In November of 2003, this new apparatus was used on the KC-135 aircraft to test cotton and cotton/polyester blend fabric specimens in microgravity. These materials were also been tested using the same apparatus in 1-g, and using a standard vertical flammability test that utilizes a flame. In this presentation, the design of the test apparatus will be briefly described. Examples of results from the KC-135 tests will be provided, including

Older people are disproportionately at risk of burn and have a high risk of dementia; however the impact of dementia on risk of burn is unknown. Linked hospitalisation and death records for individuals aged 65 years and older admitted to a NSW hospital for a burn over the ten year period 2003-2012 were analysed. Demographic and burn characteristics and health outcomes were compared for people with and without dementia. Incidence rates were calculated per 100,000 population and negative binomial regression was used to examine temporal trends. Of the 1535 older people hospitalised for a burn, 11.0% had a record of dementia. The age-standardised incidence rate for people with dementia was 22.7 per 100,000, and for people without dementia was 14.2 per 100,000 population, an incident rate ratio (IRR) of 1.6 (95%CI 1.3-2.0, p<0.0001). There was no significant change in rates over time. People with dementia were more likely to be admitted with burns to the trunk and have greater than 20% total body surface area (TBSA) burn. Mean length of stay (LOS) was more than double (24 vs 12 days) and 30-day mortality three times higher (15.4% vs 5.1%) for people with dementia. Adjusting for differences in age, sex, TBSA, inhalation injury, comorbidities and complications eliminated the increased mortality but not the difference in LOS. People with dementia were more likely to have been burnt by hot tap water (RR 2.3; 95%CI 1.8-2.8, p<0.0001) and ignition of clothing/nightwear (RR 2.6; 95% CI 1.2-5.4, p=0.0149) and to have sustained the burn in residential aged care (20.0%). Burns in people with dementia are significant injuries, which have not decreased over the past ten years despite prevention efforts to reduce burns in older people. Targeted prevention education in the home and residential aged care facilities is warranted. Copyright © 2015 Elsevier Ltd and ISBI. All rights reserved.

About 90% of the global burden of burns occurs in the low and middle income countries. In Africa it is estimated that between 17,000 and 30,000 children under five die each year due to burns. In Tanzania there are no specialized burn centers. Burn patients are often managed in the general surgical wards in most hospitals. Kilimanjaro Christian Medical Centre is one of the four tertiary referral hospitals in Tanzania. This study aimed to review the epidemiology presentation management and outcome of burn patients in this challenging environment. A cross-sectional prospective study involving 41 patients was undertaken from October 2011 to April 2012. 65.9% were males. The largest age group was below 5 years (36.6%). 19.5% were epileptic. More than half of the burns were due to open flame. 80.5% had second degree burns. 56.1% had a BSA of 15% or less and 56.1% had an APACHE score of 10 or less. It was found that 73.2% of burns occurred at home. The commonest prehospital first aid applied was honey. Only 41.5% arrived in hospital within the first 24h after burn. Among the 14.6% who had skin grafting, none had early excision of burn wound. 53.7% developed wound sepsis while 24.4% developed contractures. The mortality rate was 26.8%. Children under five are the worst affected by burns. Most patients had second degree burn wounds. Inappropriate management of the burn wound started just after injury and continued even in hospital. Mortality and complication rates are high. Copyright © 2013 Elsevier Ltd and ISBI. All rights reserved.

Tropical peatland burning in Asia has been intensifying over the last decades, emitting huge amounts of gas species and aerosol particles. Both laboratory and field studies have been conducted to investigate emission from peat burning, yet a significant variability in data still exists. We conducted a series of experiments to characterize the gas and particulate matter emitted during burning of a peat sample from Sumatra in Indonesia. Heating temperature of peat was found to regulate the ratio of CH4 to CO2 in emissions (ΔCH4/ΔCO2) as well as the chemical composition of particulate matter. The ΔCH4/ΔCO2 ratio was larger for higher temperatures, meaning that CH4 emission is more pronounced at these conditions. Mass spectrometric analysis of organic components indicated that aerosol particles emitted at higher temperatures had more unsaturated bonds and ring structures than that emitted from cooler fires. The result was consistently confirmed by nuclear magnetic resonance analysis. In addition, CH4 emitted by burning charcoal, which is derived from previously burned peat, was lower by at least an order of magnitude than that from fresh peat. These results highlight the importance of both fire history and heating temperature for the composition of tropical peat-fire emissions. They suggest that remote sensing technologies that map fire histories and temperatures could provide improved estimates of emissions.

Burns are major cause of morbidity and mortality in developing countries. Better understanding of the nature and extent of injury remains the major and only available way to halt the occurrence of the event. The present study was conducted to determine the prevalence of by self and by other unintentional burn, their comparison and the possible mode of acquisition by obtaining the history of exposure to known risk factors. A cross-sectional questionnaire based survey was conducted in Burns Centre of Civil Hospital Karachi, Pakistan and 324 hospitalized adult patients with unintentional burns were consecutively interviewed during August 2013 to February 2014. Information was collected on socio-demographic profile. The source of burn, affected body part and place of injury acquisition in terms of home, outside or work were also noted. Logistic regression model was conducted using SPSS software. Out of 324 patients, 295 (91%) had unintentional burn by self and 29 (9%) had unintentional burn by others. Male gender were 2.37 times and no schooling were 1.75 times more likely to have self-inflicted unintentional burn. Lower limb and head and neck were less likely to involve in unintentional burn by self. The burden of unintentional burn by self was considerably higher. Male gender and no schooling were found more at risk to have unintentional burn by self. Copyright © 2016 Elsevier Ltd and ISBI. All rights reserved.

The use of orbital solid rocket motors (SRM) is responsible for the release of a high number of slag and Al 2O 3 dust particles which contribute to the space debris environment. This contribution has been modeled for the ESA space debris model MASTER (Meteoroid and Space Debris Terrestrial Environment Reference). The current model version, MASTER-2005, is based on the simulation of 1076 orbital SRM firings which mainly contributed to the long-term debris environment. SRM firings on very low earth orbits which produce only short living particles are not considered. A comparison of the modeled flux with impact data from returned surfaces shows that the shape and quantity of the modeled SRM dust distribution matches that of recent Hubble Space Telescope (HST) solar array measurements very well. However, the absolute flux level for dust is under-predicted for some of the analyzed Long Duration Exposure Facility (LDEF) surfaces. This indicates that some past SRM firings are not included in the current event database. Thus it is necessary to investigate, if additional historical SRM burns, like the retro-burn of low orbiting re-entry capsules, may be responsible for these dust impacts. The most suitable candidates for these firings are the large number of SRM retro-burns of return capsules. This paper focuses on the SRM retro-burns of Russian photoreconnaissance satellites, which were used in high numbers during the time of the LDEF mission. It is discussed which types of satellites and motors may have been responsible for this historical contribution. Altogether, 870 additional SRM retro-burns have been identified. An important task is the identification of such missions to complete the current event data base. Different types of motors have been used to de-orbit both large satellites and small film return capsules. The results of simulation runs are presented.

Objective: To explore the pain experiences of adult burn patients so as to lay foundation for practical analgesic measures. Methods: Using phenomenological method in qualitative research, semi-structured interviews were conducted on 12 adult burn patients hospitalized in our burn units from May to November 2015, aiming at pain experiences from immediately after burns to 3 to 7 months after being discharged from hospital. Then the Colaizzi's analysis method was applied to analyze, induce, and refine themes of interview data. Results: After analysis, pain experiences of adult burn patients were generalized into 6 themes: deep pain experiences, heavy psychological burden, limited daily life, poor assessment and treatment of pain, different attributions of pain, and different ways of coping of pain. Conclusions: Burn pain brings harm to the patients' physiology, mentality, and daily life. Nevertheless, pain processing modes of medical staff and patients themselves are the key factors affecting patients' pain experiences. Therefore, according to the deficiency of current situation of pain management, the targeted analgesic intervention measures should be carried out from the perspectives of medical staff and patients.

Managing a patient with burning mouth syndrome

A 64-year-old woman presented with an increasing frequency of symptoms of heartburn and retrosternal pain over the last few months, and a constant and intense burning pain affecting her tongue tip, mouth and lips for the past 5 years. She found consuming hot drinks exacerbated the burning oral pain and chewing gum seemed to alleviate some of her symptoms. She thought these oral sensations were caused by frequently licking her finger tips to separate prints in her work in publishing. She had been previously diagnosed with gastro-oesophageal reflux disease (GORD), and her heartburn symptoms had been controlled until recently with lansoprazole 15 mg daily. Her past medical history included irritable bowel syndrome and depression, for which she had been treated with mebeverine and paroxetine for a number of years. She was a non-smoker and did not consume alcohol. Clinical examination was unremarkable with no oral lesions on examination. Her routine laboratory tests, including autoimmune serology, haematinics and thyroid function tests were all within normal limits. She underwent a gastroscopy, which revealed moderate reflux oesophagitis, and following commencing omeprazole 20 mg twice daily, her heartburn resolved. However, her oral burning symptoms were not affected and a diagnosis of burning mouth syndrome (BMS) was made. Following explanation and reassurance concerning the cause of her BMS symptoms, she chose not to receive treatment for this but to access cognitive behavioural therapy in the future if her symptoms worsened.

The Burns Specific Health Scale-Revised (BSHS-R) is of easy application, can be self-administered, and it is considered a good scale to evaluate various important life aspects of burn victims. To translate and culturally adapt the BSHS-R into the Brazilian-Portuguese language and to evaluate the internal consistency and convergent validity of the translated BSHS-R. The cultural adaptation of the BSHS-R included translation and back-translation, discussions with professionals and patients to ensure conceptual equivalence, semantic evaluation, and pre-test of the instrument. The Final Brazilian-Portuguese Version (FBPV) of the BSHS-R was tested on a group of 115 burn patients for internal consistency and validity of construct (using the Rosenberg Self-Esteem Scale (RSES) and the Beck Depression Inventory (BDI)). All values of Cronbach's alpha were greater than .8, demonstrating that the internal consistency of the FBPV was very high. Self-esteem was highly correlated with affect and body image (r=.59, p<.001), and with interpersonal relationships (r=.51, p<.001). Correlations between the domains of the FBPV and the BDI were all negative but larger in magnitude than the correlations with RSES. Depression was highly correlated with affect and body image (r=-.77, p<.001), and with interpersonal relationships (r=-.67, p<.001). The results showed that the adapted version of the BSHS-R into Brazilian-Portuguese fulfills the validity and reliability criteria required from an instrument of health status assessment for burn patients.

Future steady-state burning plasma facilities will access new physics regimes and modes of plasma behavior. It is vital to prepare for this both experimentally using existing facilities, and theoretically in order to develop the tools to project to and optimize these devices. An upgrade to DIII-D is proposed to address the three critical aspects where research must go beyond what we can do now: (i) torque free electron heating to address the energy, particle and momentum transport mechanisms of burning plasmas using electron cyclotron (EC) heating and full power balanced neutral beams; (ii) off-axis heating and current drive to develop the path to true fusion steady state by reorienting neutral beams and deploying EC and helicon current drive; (iii) a new divertor with hot walls and reactor relevant materials to develop the basis for benign detached divertor operation compatible with wall materials and a high performance fusion core. These elements with modest incremental cost and enacted as a user facility for the whole US program will enable the US to lead on ITER and take a decision to proceed with a Fusion Nuclear Science Facility.

Burn wound healing involves a series of complex processes which are subject to intensive investigations to improve the outcomes, in particular, the healing time and the quality of the scar. Burn injuries, especially severe ones, are proving to have devastating effects on the affected patients. Stem cells have been recently applied in the field to promote superior healing of the wounds. Not only have stem cells been shown to promote better and faster healing of the burn wounds, but also they have decreased the inflammation levels with less scar progression and fibrosis. This review aims to highlight the beneficial therapeutic effect of stem cells in burn wound healing and to discuss the involved pathways and signaling molecules. The review covers various types of burn wound healing like skin and corneal burns, along with the alternative recent therapies being studied in the field of burn wound healing. The current reflection of the attitudes of people regarding the use of stem cells in burn wound healing is also stated. PMID:26236731

In order to be useful, animal models should be reproducible and consistent regardless of sampling bias, investigator creating burn, and burn location. We determined the variability in burn depth based on biopsy location, burn location and investigator in a porcine model of partial thickness burns. 24 partial thickness burns (2.5 cm by 2.5 cm each) were created on the backs of 2 anesthetized pigs by 2 investigators (one experienced, one inexperienced) using a previously validated model. In one of the pigs, the necrotic epidermis covering each burn was removed. Five full thickness 4mm punch biopsies were obtained 1h after injury from the four corners and center of the burns and stained with Hematoxylin and Eosin and Masson's trichrome for determination of burn depth by a board certified dermatopathologist blinded to burn location and investigator. Comparisons of burn depth by biopsy location, burn location and investigator were performed with t-tests and ANOVA as appropriate. The mean (SD) depth of injury to blood vessels (the main determinant of burn progression) in debrided and non-debrided pigs pooled together was 1.8 (0.3)mm, which included 75% of the dermal depth. Non-debrided burns were 0.24 mm deeper than debrided burns (P<0.001). Burn depth increased marginally from cephalic to caudal in non-debrided burns, but showed no statistical differences for these locations, in debrided burns. Additionally, there were also no statistical differences in burn depths from midline to lateral in either of these burn types. Burn depth was similar for both investigators and among biopsy locations. Burn depth was greater for caudal locations in non-debrided burns and overall non-debrided burns were deeper than debrided burns. However, burn depth did not differ based on investigator, biopsy site, and medial-lateral location. Copyright © 2015 Elsevier Ltd and ISBI. All rights reserved.

Several studies have shown the importance of the sympathetic nervous system in bone metabolism. There is an evidence of sympathetic skin response (SSR) impairment in electrical burn patients up to 2 years after their injuries. The acute phase of burn is accompanied by increased bone resorption. Whether the prolonged dysfunction of sympathetic nervous system may result in bone metabolism derangement even after the acute phase of electrical burn is the inspiring question for this study. And we tried to find correlation between SSR abnormality and areal bone mineral density (BMD) in electrical burn patients 6 months or more after the incidents. 42 electrical burn patients (≥6 months prior to study) who did not have a known joint or bone disease, history of neuropathy (central or peripheral), diabetes mellitus or consumption of any drug affecting the autonomic nervous system or evidence of neuropathy in nerve conduction study were recruited. We also gathered a control group of 50 healthy subjects (without electrical burn or the exclusion criteria). They went under dual energy X-ray absorptiometry and SSR study. Data were analyzed statistically with SPSS 16.0 making use of independent t-test and Pearson correlation coefficient. P<0.05 was considered significant statistically. Areal BMD was significantly lower in electrical burn patients than control group (P<0.001). SSR latency was significantly prolonged and its amplitude was significantly reduced in burn patients compared to control group (P<0.001). In burn patients there was an inverse correlation of areal BMD of lumbar vertebrae, left femur neck and total femur with SSR latency and a direct correlation of areal BMD with SSR amplitude. In control group there was just direct correlation of areal BMD of lumbar vertebrae and left femur neck with SSR amplitude. Electrical burn patients are at risk of reduced areal BMD long after their injuries. Sympathetic derangement and impaired SSR are correlated with reduction in

Analysis of Geodynamical Conditions of Region of Burning Coal Dumps Location

2017-12-01

Spontaneous combustion of coal dumps and their impact on the environment of mining regions remain important environmental problem, in spite of the measures that are being taken. The paper presents the hypothesis, which states that the location of coal dumps at the boundaries of geodynamically active crust blocks promotes the appearance of conditions for their combustion. At present geodynamically active crust faults that affect the operating conditions of engineering facilities are observed not only in the areas of tectonic activity, but also on platforms. According to the concept of geodynamical zoning, geodynamically dangerous zones for engineering structures can be not only large, well-developed crust faults, but also just formed fractures that appear as boundaries of geodynamically impacting and hierarchically ordered crust blocks. The purpose of the study is to estimate the linkage of burning dumps to boundaries of geodynamically active crust blocks (geodynamically dangerous zones) for subsequent development of recommendations for reducing environmental hazard. The analysis of 27 coal dumps location was made for one of the Eastern Donbass regions (Russia). Nine of sixteen burning dumps are located in geodynamically dangerous zones, which, taking into account relatively small area occupied by all geodynamically dangerous zones, results that there is a concentration (pcs/km2) of burning dumps, which is 14 times higher than the baseline value. While the probability of accidental obtaining of such a result is extremely low, this can be considered as the evidence of the linkage of burning dumps to geodynamically dangerous zones. Taking into account the stressed state of the rock massif in this region, all geodynamically dangerous zones can be divided into compression and tension zones. The statistic is limited, but nevertheless in tension zones the concentration of burning dumps is 2 times higher than in compression zones. Available results of thermal monitoring of

Kilburn, Nadia; Dheansa, Baljit

2014-12-01

This pilot study aimed to gain empirical data on the social and economic impacts of child burns on children and parents, in the context of the outpatient setting. A questionnaire was completed by 52 parents of paediatric patients attending the burns outpatient department at Queen Victoria Hospital (QVH), East Grinstead, for at least the third time. Children's medical notes were used to extract demographic and medical data. Quantitative data was analyzed statistically and qualitative data was analyzed manually using content analysis. The financial burden related to the injury posed the greatest impact on parents, and was mainly associated with making the journey to the hospital, with lower income households being most affected. Self-employed parents and those who had to attend more than 6 hospital appointments also ran into difficulties. On the whole, there was not a considerable social impact on the burn-injured child, which may reflect the minor nature of burns in this study (mean depth partial thickness, median TBSA 1.0%). Parents were shown to perceive a greater impact from their child's burn injury than their child. Certain groups of parents were identified as requiring additional support following the burn injury.

Pain in the tongue or oral tissues described as "burning" has been referred to by many terms including burning mouth syndrome. When a burning sensation in the mouth is caused by local or systemic factors, it is called secondary burning mouth syndrome and when these factors are treated the pain will resolve. When burning mouth syndrome occurs in the absence of identified risk indicators, the term primary burning mouth syndrome is utilized. This article focuses on descriptions, etiologic theories, and management of primary burning mouth syndrome, a condition for which underlying causative agents have been ruled out. Copyright © 2013.

Biomass burning represents one of the largest sources of particulate matter to the atmosphere, which results in a significant perturbation to the Earth's radiative balance coupled with serious negative impacts on public health. Globally, biomass burning aerosols are thought to exert a small warming effect of 0.03 Wm-2, however the uncertainty is 4 times greater than the central estimate. On regional scales, the impact is substantially greater, particularly in areas such as the Amazon Basin where large, intense and frequent burning occurs on an annual basis for several months (usually from August-October). Furthermore, a growing number of people live within the Amazon region, which means that they are subject to the deleterious effects on their health from exposure to substantial volumes of polluted air. Initial results from the South American Biomass Burning Analysis (SAMBBA) field experiment, which took place during September and October 2012 over Brazil, are presented here. A suite of instrumentation was flown on-board the UK Facility for Airborne Atmospheric Measurement (FAAM) BAe-146 research aircraft and was supported by ground based measurements, with extensive measurements made in Porto Velho, Rondonia. The aircraft sampled a range of conditions with sampling of fresh biomass burning plumes, regional haze and elevated biomass burning layers within the free troposphere. The physical, chemical and optical properties of the aerosols across the region will be characterized in order to establish the impact of biomass burning on regional air quality, weather and climate.

Does nurses'perceived burn prevention knowledge and ability to teach burn prevention correlate with their actual burn prevention knowledge?

2010-01-01

The purpose of this study was to explore the relationship among nurses'perceived burn prevention knowledge, their perceived ability to teach about burn prevention, and their actual burn prevention knowledge and to test if their actual burn knowledge could be predicted by these perceived measures. A two-page, anonymous survey that included a 10-item burn prevention knowledge test and an assessment of nurses'perceived knowledge of burn prevention and their perceived ability to teach burn prevention was administered to 313 nurses. Actual burn prevention knowledge was determined and the correlation among actual burn prevention knowledge, perceived knowledge, and perceived ability to teach was determined. Differences in these outcome variables based on specialty area were tested using analysis of variance techniques. Generalized linear modeling techniques were used to investigate which variables significantly predict a nurse's actual burn prevention knowledge. Test for interaction effects were performed, and significance was set at .05. Responding nurses (N = 265) described practicing in a variety of settings, such as pediatric settings (40.2%, n = 105), emergency departments (25.4%, n = 86), medical/surgical settings (8.4%, n = 22), and one pediatric burn setting (4.1%, n = 14), with all specialty areas as having similar actual burn prevention knowledge (P = .052). Seventy-seven percent of the nurses said they never taught about burn prevention (n = 177). Perceived knowledge and actual knowledge (r = .124, P = .046) as well as perceived knowledge and perceived ability were correlated (r = .799, P < .001). Significant predictors of actual knowledge were years in practice (beta = -0.063, P = .034), years in current area (beta = 0.072, P = .003), perceived knowledge (beta = 0.109, P = .042), and perceived ability (beta = 0.137, P = .019). All nurses, regardless of specialty area, have poor burn prevention knowledge, which is correlated with their perceived lack of

To evaluate demographic and socioeconomic factors associated with assault burn injuries. Assault by burning demonstrates a rare but severe public health issue and accounts for unique injury characteristics in the burn intensive care unit (BICU). We conducted a retrospective cohort study involving patients with thermal injuries admitted to the BICU of a university hospital. The patient cohort was divided into two groups (ABI group: patients with assault burns, n=41; population of all other burned patients admitted to the BICU, n=1202). Bivariate and multivariate analyses including demographic and socioeconomic data were used to identify factors associated with assault burns. Forty-one assault-related burn victims were identified in the study period. This represents 3.3% of all significant burns admitted. Comparing battery victims with the control population, assault patients were more likely to be young (mean age 36.2 years vs. 42.2 years) and immigrants (41.5% vs. 15.1%). Furthermore, marital status (65.9% vs. 40.8% singles), employment status (36.6% vs. 9.7% unemployed) and insurance status (41.5% vs. 12.3% social insurance) were significantly different in the bivariate analysis. Logistic regression evaluation identified three variables that were independently associated with assault burns: younger age (< or =25 years) (odds ratio, 2.54 [95% confidence interval, 1.29-5.02]; p=0.007), ethnic minority (odds ratio, 3.71 [95% confidence interval, 1.91-7.20]; p<0.001) and unemployment (odds ratio, 4.02 [95% confidence interval, 2.03-7.97]; p<0.001). The high incidence of youngsters, unemployment and the great proportion of immigrants in victims of assault might provide several opportunities for community-based psychosocial and occupational programs. A multidisciplinary approach targeting issues specific to the violent nature of the injury and the socioeconomic background of the victims may be of benefit to improve their perspectives for rehabilitation.

Recently burned forests in western North America provide nesting habitat for many species of cavity-nesting birds. However, little is understood about the time frame and the variables affecting occupancy of postfire habitats by these birds. We studied factors influencing the occupancy and reuse of nest cavities from 1-7 years after fire in two burned sites of western Idaho during 1994-1999. Tree cavities were used for nesting by 12 species of cavity nesters that were classified by the original occupant (strong excavator, weak excavator, or nonexcavator) of 385 nest cavities. We used logistic regression to model cavity occupancy by strong excavators (n = 575 trials) and weak excavators (n = 206 trials). Year after fire had the greatest influence on occupancy of nest cavities for both groups, while site of the burn was secondarily important in predicting occupancy by strong excavators and less important for weak excavators. Predicted probability of cavity occupancy was highest during the early years (1-4) after fire, declined over time (5-7 years after fire), and varied by site, with a faster decline in the smaller burned site with a greater mosaic of unburned forest. Closer proximity and greater interspersion of unburned forest (15% unburned) may have allowed a quicker recolonization by nest predators into the smaller burn compared to the larger burn with few patches of unburned forest (4% unburned). In combination with time and space effects, the predicted probability of cavity occupancy was positively affected by tree and nest heights for strong and weak excavators, respectively.

Burns are common injuries that cause problems to societies throughout the world. In order to reduce the cost of burn treatment in children, it is extremely important to determine the burn epidemiology and the cost of medicines used in burn treatment. The present study used a retrospective design, with data collected from medical records of 140 paediatric patients admitted to a burn centre between 1 January 2009 and 31 December 2009. Medical records were examined to determine burn epidemiology, medication administered, dosage, and duration of use. Descriptive statistical analysis was completed for all variables; chi-square was used to examine the relationship between certain variables. It was found that 62.7% of paediatric burns occur in the kitchen, with 70.7% involving boiling water; 55.7% of cases resulted in third-degree burns, 19.3% required grafting, and mean duration of hospital stay was 27.5 ± 1.2 days. Medication costs varied between $1.38 US dollars (USD) and $14,159.09, total drug cost was $46,148.03 and average cost per patient was $329.63. In this study, the medication cost for burn patients was found to be relatively high, with antibiotics comprising the vast majority of medication expenditure. Most paediatric burns are preventable, so it is vital to educate families about potential household hazards that can be addressed to reduce the risk of a burn. Programmes are also recommended to reduce costs and the inappropriate prescribing of medication. Copyright © 2012 Elsevier Ltd and ISBI. All rights reserved.

mortality was 0.9% (n = 20), with mean TBSA involved of 61.5%. The majority of pediatric burn injuries are scald burns that occur at home and primarily affect the lower extremities in Caucasian and African-American males. Among Caucasian teenagers flame burns predominate. Mean length of stay was 10 days, 23% of patients required skin grafting surgery, and mortality was 0.9%. The results of this study highlight the need for primary prevention programs focusing on avoiding home scald injuries in the very young, as well as fire safety training for teenagers.

Burn Wound Infections

Church, Deirdre; Elsayed, Sameer; Reid, Owen; Winston, Brent; Lindsay, Robert

2006-01-01

Burns are one of the most common and devastating forms of trauma. Patients with serious thermal injury require immediate specialized care in order to minimize morbidity and mortality. Significant thermal injuries induce a state of immunosuppression that predisposes burn patients to infectious complications. A current summary of the classifications of burn wound infections, including their diagnosis, treatment, and prevention, is given. Early excision of the eschar has substantially decreased the incidence of invasive burn wound infection and secondary sepsis, but most deaths in severely burn-injured patients are still due to burn wound sepsis or complications due to inhalation injury. Burn patients are also at risk for developing sepsis secondary to pneumonia, catheter-related infections, and suppurative thrombophlebitis. The introduction of silver-impregnated devices (e.g., central lines and Foley urinary catheters) may reduce the incidence of nosocomial infections due to prolonged placement of these devices. Improved outcomes for severely burned patients have been attributed to medical advances in fluid resuscitation, nutritional support, pulmonary and burn wound care, and infection control practices.

To document the incidence of septic and mechanical complications associated with femoral venous catheters in a subgroup of patients thought to be at particularly high risk of both: young children with large burns. An analysis of data collected prospectively on all femoral venous catheters placed during a 4-year period at a regional pediatric burn facility. There were 224 femoral catheters placed in 86 children with an average age of 5.3 +/- 5.1 years and an average burn size of 38% +/- 23%. Catheters were left in place for a mean duration of 5.7 days. Catheter-related sepsis occurred with 4.9% of the catheters, and mechanical complications occurred in 3.5% of the patients. There was no statistically significant association between the risk of catheter sepsis and the placement of catheters through burned versus unburned skin. Similarly, the risk of sepsis was equivalent between lines placed over a guide wire and those placed of a new site. Femoral venous catheters are safe in burned children and are associated with a low incidence of infectious and mechanical complications.

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 of age, admission within 96 hours after injury, and >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 ABA sepsis criteria), pneumonia, acute respiratory distress syndrome, and multiple organ failure (DENVER2 score >3) for both children (<16 years) and adults (16–65 years). 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.

Prescribed burning impact on forest soil properties--a Fuzzy Boolean Nets approach.

PubMed

Castro, Ana C Meira; Paulo Carvalho, Joao; Ribeiro, S

2011-02-01

The Portuguese northern forests are often and severely affected by wildfires during the Summer season. These occurrences significantly affect and negatively impact all ecosystems, namely soil, fauna and flora. In order to reduce the occurrences of natural wildfires, some measures to control the availability of fuel mass are regularly implemented. Those preventive actions concern mainly prescribed burnings and vegetation pruning. This work reports on the impact of a prescribed burning on several forest soil properties, namely pH, soil moisture, organic matter content and iron content, by monitoring the soil self-recovery capabilities during a one year span. The experiments were carried out in soil cover over a natural site of Andaluzitic schist, in Gramelas, Caminha, Portugal, which was kept intact from prescribed burnings during a period of four years. Soil samples were collected from five plots at three different layers (0-3, 3-6 and 6-18) 1 day before prescribed fire and at regular intervals after the prescribed fire. This paper presents an approach where Fuzzy Boolean Nets (FBN) and Fuzzy reasoning are used to extract qualitative knowledge regarding the effect of prescribed fire burning on soil properties. FBN were chosen due to the scarcity on available quantitative data. The results showed that soil properties were affected by prescribed burning practice and were unable to recover their initial values after one year. Copyright © 2010 Elsevier Inc.

The clinical judgment of expert burn surgeons is currently the standard on which diagnostic and therapeutic decisionmaking regarding burn injuries is based. Multispectral imaging (MSI) has the potential to increase the accuracy of burn depth assessment and the intraoperative identification of viable wound bed during surgical debridement of burn injuries. A highly accurate classification model must be developed using machine-learning techniques in order to translate MSI data into clinically-relevant information. An animal burn model was developed to build an MSI training database and to study the burn tissue classification ability of several models trained via common machine-learning algorithms. The algorithms tested, from least to most complex, were: K-nearest neighbors (KNN), decision tree (DT), linear discriminant analysis (LDA), weighted linear discriminant analysis (W-LDA), quadratic discriminant analysis (QDA), ensemble linear discriminant analysis (EN-LDA), ensemble K-nearest neighbors (EN-KNN), and ensemble decision tree (EN-DT). After the ground-truth database of six tissue types (healthy skin, wound bed, blood, hyperemia, partial injury, full injury) was generated by histopathological analysis, we used 10-fold cross validation to compare the algorithms' performances based on their accuracies in classifying data against the ground truth, and each algorithm was tested 100 times. The mean test accuracy of the algorithms were KNN 68.3%, DT 61.5%, LDA 70.5%, W-LDA 68.1%, QDA 68.9%, EN-LDA 56.8%, EN-KNN 49.7%, and EN-DT 36.5%. LDA had the highest test accuracy, reflecting the bias-variance tradeoff over the range of complexities inherent to the algorithms tested. Several algorithms were able to match the current standard in burn tissue classification, the clinical judgment of expert burn surgeons. These results will guide further development of an MSI burn tissue classification system. Given that there are few surgeons and facilities specializing in burn care

U.S. military forces have historically relied on open burning as an expedient method of volume reduction and treatment of solid waste during the conflicts in Afghanistan and Iraq. This study is the first effort to characterize a broad range of pollutants and their emission factors during the burning of military waste and the effects that recycling efforts, namely removing plastics, might have on emissions. Piles of simulated military waste were constructed, burned, and emissions sampled at the U.S. Environmental Protection Agency (EPA) Open Burn Testing Facility (OBTF), Research Triangle Park, NC. Three tests contained polyethylene terephthalate (PET #1 or PET) plastic water bottles and four did not. Emission factors for polycyclic aromatic hydrocarbons (PAHs), volatile organic compounds (VOCs), particulate matter (PM(10), PM(2.5)), polychlorinated and polybrominated dioxins/furans (PCDD/F and PBDD/F), and criteria pollutants were determined and are contained within. The average PCDD/F emission factors were 270 ng-toxic equivalency (TEQ) per kg carbon burned (ng-TEQ/kg Cb), ranging from 35 to 780 ng-TEQ/kg Cb. Limited testing suggests that targeted removal of plastic water bottles has no apparent effect on reducing pollutants and may even promote increased emissions.

This study evaluated the impact of a newly implemented protocol for superficial to mid-dermal partial thickness burns which involves early surgery and rapid coverage with biosynthetic dressing in a specialized national burns center in Singapore. Consecutive patients with 5% or greater total body surface area (TBSA) superficial to mid-dermal partial thickness burns injury admitted to the Burns Centre at the Singapore General Hospital between August and December 2014 for surgery within 48 hours of injury were prospectively recruited into the study to form the protocol group. Comparable historical cases from the year 2013 retrieved from the burns center audit database were used to form the historical control group. Demographics (age, sex), type and depth of burns, %TBSA burnt, number of operative sessions, and length of stay were recorded for each patient of both cohorts. Thirty-nine burns patients managed under the new protocol were compared with historical control (n = 39) comparable in age and extensiveness of burns. A significantly shorter length of stay (P < 0.05) per TBSA burns was observed in the new protocol group (0.74 day/%TBSA) versus historical control (1.55 day/%TBSA). Fewer operative sessions were needed under the new protocol for burns 10% or greater TBSA burns (P < 0.05). The authors report their promising experience with a newly implemented protocol for surgically managed burns patients which involves early surgery and appropriate use of biosynthetic dressing on superficial to mid-dermal partial thickness burns. Clinically, shorter lengths of stay, fewer operative sessions, and decreased need for skin grafting of burns patient were observed.

Facial scar and deformation caused by burn injury severely affect physical and psychological well-being of pediatric burn patients, which needs medical workers and pediatric burn patients' family members to pay much attention to and to perform early rehabilitation treatment. Pressure therapy is an important rehabilitative strategy for pediatric burn patients with facial scar, mainly including wearing headgears and transparent pressure facemasks, which have their own features. To achieve better treatment results, pressure therapy should be chosen according to specific condition of pediatric burn patients and combined with other assistant therapies. Successful rehabilitation for pediatric burn patients relies on cooperation of both family members of pediatric burn patients and society. Rehabilitation knowledge should be provided to parents of pediatric burn patients to acquire their full support and cooperation in order to achieve best therapeutic effects and ultimately to rebuild physical and psychological well-being of pediatric burn patients.

Nutritional support plays an important role in the treatment of patients with burns. Due to the severe hypercatabolism that develops in these patients, oral support is insufficient in most cases, and this makes it essential to initiate artificial nutritional support (either enteral or parenteral). Enteral nutrition is more physiological than parenteral, and data exist which show that in patients with burns, enteral nutrition exercises a protective effect on the intestine and may even reduce the hypermetabolic response in these patients. The purpose of the study was to evaluate the effectiveness and tolerance of enteral nutritional support with a hypercaloric, hyperproteic diet with a high content of branched amino acids in the nutritional support of patients suffering from burns. The study included 12 patients (8 males and 4 females), admitted to the Burns Unit. Average age was 35 +/- 17 years (range: 21-85 years). The percentage of body surface affected by the burns was 10% in two cases, between 10-30% in three cases, between 30-50% in five cases and over 50% in two cases. Initiation of the enteral nutrition was between twenty-four hours and seven days after the burn. The patients were kept in the unit until they were discharged, and the average time spent in the unit was 31.5 days (range: 17-63 days). Total energetic requirements were calculated based on Harris-Benedict, with a variable aggression factor depending on the body surface burned, which varied from 2,000 and 4,000 cal day. Nitrogenous balance was determined on a daily basis, and plasmatic levels of total proteins, albumin and prealbumin on a weekly basis. There was a significant difference between the prealbumin values at the initiation and finalization of the enteral nutrition (9.6 +/- 2.24 mg/dl compared with 19.75 +/- 5.48 mg/dl; p < 0.001). The nitrogenous balance improved, changing from -5.4 in the second week to positive values by the fourth and fifth weeks of treatment. Tolerance to the enteral

Pediatric burns have a long-term social impact. This is more apparent in a developing country such as India, where their incidence and morbidity are high. The aim of this study was to provide recent prospective epidemiological data on pediatric burns in India and to suggest future preventive strategies. Children up to 18 years old admitted to the Department of Burns, Plastic & Maxillofacial Surgery, VMMC & Safdarjung Hospital, New Delhi, between January and December 2014 were included in the study. Data regarding age, sex, etiology, total body surface area (TBSA), circumstances of injury, and clinical assessment were collected. The Mann-Whitney test or Kruskal-Wallis test or ANOVA was used to compare involved TBSA among various cohort groups accordingly. Univariate and multivariate linear regression analyses were used to determine the predictors of TBSA. There were a total of 475 patients involved in the study, including seven suicidal burns, all of whom were females with a mean age greater than the cohort average. Age, type of burns, mode of injury, presence or absence of inhalation injury, gender, and time of year (quarter) for admission were found to independently affect the TBSA involved. Electrical burns also formed an important number of presenting burn patients, mainly involving teenagers. Several societal issues have come forth, e.g., child marriage, child labor, and likely psychological problems among female children as suggested by a high incidence of suicidal burns. This study also highlights several issues such as overcrowding, lack of awareness, dangerous cooking practices, and improper use of kerosene oil. There is an emergent need to recognize the problems, formulate strategies, spread awareness, and ban or replace hazardous substances responsible for most burn accidents.

Introduction Burning mouth syndrome mainly affects women, particularly after the menopause, when its prevalence may be 18-33%. Methods and outcomes We conducted a systematic review and aimed to answer the following clinical question: What are the effects of treatments for burning mouth syndrome? We searched: Medline, Embase, The Cochrane Library, and other important databases up to February 2007 (BMJ Clinical Evidence reviews are updated periodically, please check our website for the most up-to-date version of this review). We included harms alerts from relevant organisations such as the US Food and Drug Administration (FDA) and the UK Medicines and Healthcare products Regulatory Agency (MHRA). Results We found 12 systematic reviews, RCTs, or observational studies that met our inclusion criteria. We performed a GRADE evaluation of the quality of evidence for interventions. Conclusions In this systematic review we present information relating to the effectiveness and safety of the following interventions: anaesthetics (local), antidepressants, benzodiazepines (topical clonazepam), benzydamine hydrochloride, cognitive behavioural therapy (CBT), dietary supplements, and hormone replacement therapy (HRT) in postmenopausal women.

While mortality rates after burn are low, physical and psychosocial impairments are common. Clinical research is focusing on reducing morbidity and optimizing quality of life. This study examines self-reported Satisfaction With Life Scale scores in a longitudinal, multicenter cohort of survivors of major burns. Risk factors associated with Satisfaction With Life Scale scores are identified. Data from the National Institute on Disability, Independent Living, and Rehabilitation Research (NIDILRR) Burn Model System (BMS) database for burn survivors greater than 9 years of age, from 1994 to 2014, were analyzed. Demographic and medical data were collected on each subject. The primary outcome measures were the individual items and total Satisfaction With Life Scale (SWLS) scores at time of hospital discharge (pre-burn recall period) and 6, 12, and 24 months after burn. The SWLS is a validated 5-item instrument with items rated on a 1-7 Likert scale. The differences in scores over time were determined and scores for burn survivors were also compared to a non-burn, healthy population. Step-wise regression analysis was performed to determine predictors of SWLS scores at different time intervals. The SWLS was completed at time of discharge (1129 patients), 6 months after burn (1231 patients), 12 months after burn (1123 patients), and 24 months after burn (959 patients). There were no statistically significant differences between these groups in terms of medical or injury demographics. The majority of the population was Caucasian (62.9%) and male (72.6%), with a mean TBSA burned of 22.3%. Mean total SWLS scores for burn survivors were unchanged and significantly below that of a non-burn population at all examined time points after burn. Although the mean SWLS score was unchanged over time, a large number of subjects demonstrated improvement or decrement of at least one SWLS category. Gender, TBSA burned, LOS, and school status were associated with SWLS scores at 6 months

Facial burns around the eyes and eyelid ectropion can lead to corneal exposure, irritation, dryness, epiphora, infection or visual loss. We undertook a review of the published articles describing management of eyelid burns as well as methods to treat or prevent ectropion. We describe early experience of a surgical technique that we have found to mitigate ectropion in facial burns with peri-ocular involvement. Two illustrative cases with our surgical technique is described from our experience of three cases. We reviewed the literature using the PubMed and EMBASE databases using the search terms 'burn' and 'ectropion'. The literature review produced a total of 17 relevant papers. Treatment options for eyelid burns were varied and were invariably level 4 or 5 evidence. Various techniques were used to treat eyelid burns including the use of a full thickness skin graft with or without concurrent scar contracture release but also use of a local flap reconstruction with or without a tissue expander or release of the underlying muscle. Other techniques included canthoplasty, Z-plasty, forehead flaps, fat transfer, and tarsorrhaphy with full thickness skin grafting. In general, the focus of articles was therapeutic and reconstructive rather than pre-emptive/preventative management. We describe our early experience of a novel technique for temporary lateral tarsorrhaphy with forehead hitch which protexts the globe and counters the scar- and gravity-related ectropic effects on the lower eyelids. Facial burns pose a difficult problem to the burn surgeon, especially when the eyelids are affected, both directly or indirectly. The optimal surgical management of eyelid burns remains unclear and the literature base lies mainly in the domain of case series. We review the literature on this subject and tabulate our findings and also describe our contribution to this area with a method of lateral and lower lid elevator that we have found valuable.

From July 13, 1988, to May 14, 1995, 1585 patients with burns and no other injuries besides inhalation were treated; 4.5% did not survive. Artificial neural networks were trained on patient presentation data with known outcomes on 90% of the randomized cases. The remaining cases were then used to predict survival and length of stay in cases not trained on. Survival was predicted with more than 98% accuracy and length of stay to within a week with 72% accuracy in these cases. For anatomic area involved by burn, burns involving the feet, scalp, or both had the largest negative effect on the survival prediction. In survivors burns involving the buttocks, transport to this burn center by the military or by helicopter, electrical burns, hot tar burns, and inhalation were associated with increasing the length of stay prediction. Neural networks can be used to accurately predict the clinical outcome of a burn. What factors affect that prediction can be investigated.

Aerosol Properties Downwind of Biomass Burns Field Campaign Report

We determined the morphological, chemical, and thermal properties of aerosol particles generated by biomass burning during the Biomass Burning Observation Project (BBOP) campaign during the wildland fire season in the Pacific Northwest from July to mid-September, 2013, and in October, 2013 from prescribed agricultural burns in the lower Mississippi River Valley. BBOP was a field campaign of the U.S. Department of Energy (DOE)’s Atmospheric Radiation Measurement (ARM) Climate Research Facility. The morphological information was both two-dimensional, as is typical of most microscopy images and that have many of the characteristic of shadows in that they lack depth data, and three-dimensionalmore » (3D). The electron tomographic measurements will provided 3D data, including the presence and nature of pores and interstices, and whether the individual particles are coated by or embedded within other materials. These microphysical properties were determined for particles as a function of time and distance from the respective sources in order to obtain detailed information regarding the time evolution of changes during aging.« less

Satellite data driven modeling system for predicting air quality and visibility during wildfire and prescribed burn events

The Alabama Forestry Commission (AFC) is responsible for wildfire control and also prescribed burn management in the state of Alabama. Visibility and air quality degradation resulting from smoke are two pieces of information that are crucial for this activity. Currently the tools available to AFC are the dispersion index available from the National Weather Service and also surface smoke concentrations. The former provides broad guidance for prescribed burning activities but does not provide specific information regarding smoke transport, areas affected and quantification of air quality and visibility degradation. While the NOAA operational air quality guidance includes surface smoke concentrations from existing fire events, it does not account for contributions from background aerosols, which are important for the southeastern region including Alabama. Also lacking is the quantification of visibility. The University of Alabama in Huntsville has developed a state-of-the-art integrated modeling system to address these concerns. This system based on the Community Air Quality Modeling System (CMAQ) that ingests satellite derived smoke emissions and also assimilates NASA MODIS derived aerosol optical thickness. In addition, this operational modeling system also simulates the impact of potential prescribed burn events based on location information derived from the AFC prescribed burn permit database.

2018-01-01

Objectives This study aimed to identify priority policy issues and health system research questions associated with recovery outcomes for burns survivors in India. Design Qualitative inquiry; data were collected through semistructured in-depth interviews and focus group discussions. Setting Nine sites in urban and rural settings across India, through primary, secondary and tertiary health facilities. Participants Healthcare providers, key informants, burns survivors and/or their carers. Results Participants acknowledged the challenges of burns care and recovery, and identified the need for prolonged rehabilitation. Challenges identified included poor communication between healthcare providers and survivors, limited rehabilitation services, difficulties with transportation to health facility and high cost associated with burns care. Burns survivors and healthcare providers identified the stigma attached with burns as the biggest challenge within the healthcare system, as well as in the community. Systems barriers (eg, limited infrastructure and human resources), lack of economic and social support, and poor understanding of recovery and rehabilitation were identified as major barriers to recovery. Conclusions Though further research is needed for addressing gaps in data, strengthening of health systems can enable providers to address issues such as developing/providing, protocols, capacity building, effective coordination between key organisations and referral networks.

To assess the amount of allograft used in the past treatment of major burns and calculate a figure to guide estimation of the quantity of allograft required to treat future patients and aid resource planning. A retrospective observational study. Records of 143 patients treated with major burns at a regional centre, from January 2004 to November 2008 were accessed with biometric data and quantity of allograft used being recorded. This data was used to calculate an allograft index (cm² allograft used/burn surface area (cm²)) (AI) for each patient. 112 of the 143 patients had complete sets of data, of the 112, 89 patients survived the initial stay in hospital. For all data average AI=1.077 ± 0.090. AI varied according to burn % area with burns < 40% requiring 0.490 cm² allo/cm²burn, increasing in a logarithmic fashion (R²=0.995) for burn areas > 40%. The ability to estimate deceased donor skin requirements based on % body surface area affected is important in the care planning for patients with major burns. Our findings of 0.5 cm² allograft/cm² burn for injuries less than 40% TBSA, increasing to 1.82 cm² allograft/cm² burn for injuries up to 80% TBSA can be used for planning purposes for individual services and for burn disaster planning.

Cutaneous burns associated with microscope-use are perceived to be uncommon adverse events in microsurgery. Currently, it is unknown what factors are associated with these iatrogenic events. In this report, we describe the case of a 1-year-old patient who suffered a full thickness skin burn from a surgical microscope after a L4-S1 laminectomy. Additionally, we present a systematic review of the literature that assessed the preoperative risk, outcome, and management of iatrogenic microscope skin burns. Lastly, a summary of the Food and Drug Administration's (FDA) Manufacturer and User Facility Device Experience (MAUDE) database of voluntary adverse events was reviewed and analyzed for clinical cases of microscope thermal injuries. The systematic literature review identified only seven articles related to microsurgery-related cutaneous burns. From these seven studies, 15 clinical cases of iatrogenic skin burns were extracted for analysis. The systematic review of the FDA MAUDE database revealed only 60 cases of cutaneous burns associated with surgical microscopes since 2004. Few cases of microscope burns have been described in the literature; this report is, to our knowledge, one of the first comprehensive reports of this iatrogenic event in the literature.

In its first four years of operation, the California Burn Registry recorded 3,332 cases of burns, of which 73.1% were in male and 26.9% were in female patients of all ages. The average total body surface area burned was 15.4±0.3%. Flame burns were the most common (31.4%). Other common sources included scalds (24.5%) and flammable liquids (12.9%). Several other causes were cited with less frequency. Burns taking place at home occurred more commonly than at all other locations combined. In all, 221 deaths (6.6%) were reported, most (66.1%) of which were due to flame burns. PMID:4013280

Terminal Maturation of Orthochromatic Erythroblasts Is Impaired in Burn Patients.

2018-02-20

Mechanisms of erythropoietin (Epo)-resistant anemia in burn patients are poorly understood. We have recently found that administering a nonselective beta 1,2-adrenergic blocker propranolol (PR) was effective in reversing myelo-erythroid commitment through MafB regulation and increase megakaryocyte erythrocyte progenitors in burn patients' peripheral blood mononuclear cell (PBMC)-derived ex vivo culture system. Having known that Epo-dependent proliferation of early erythroblasts is intact after burn injury, here we inquired whether or not Epo-independent maturation stage of erythropoiesis is affected by burn injury and the relative role of PR on late-stage erythropoiesis. While majority of erythropoiesis occurs in the bone marrow, maturation into reticulocytes is crucial for their release into sinusoids to occupy the peripheral circulation for which enucleation is vital. peripheral blood mononuclear cells (PBMCs) from burn patients were extended beyond commitment and proliferation stages to late maturation stage in ex vivo culture to understand the role of PR in burn patients. Burn impedes late maturation of orthochromatic erythroblasts into reticulocytes by restricting the enucleation step. Late-stage erythropoiesis is impaired in burn patients irrespective of PR treatment. Further, substituting the microenvironment with control plasma (homologous) in place of autologous plasma rescues the conversion of orthochromatic erythroblasts to reticulocytes. Results show promise in formulating interventions to regulate late-stage erythropoiesis, which can be used in combination with PR to reduce the number of transfusions.

Simulated Rainfall experiments on burned areas

Rulli, Maria Cristina

2010-05-01

Simulated Rainfall experiments were carried out in a Mediterranean area located in Italy, immediately after a forest fire occurrence, to evaluate the effects of forest fire on soil hydraulic properties, runoff and erosion. The selected study area was frequently affected by fire in the last years. Two adjacent 30 mq plots were set up with common physiographic features, and the same fire history, except for the last fire, which burned only one of them. Since both plots were previously subject to the passage of fire 6 years before the last one, one compares the hydrologic response and erosion of an area recently burned (B00) with that of an area burnt 6 years before (B06). Several rainfall simulations were carried out considering different pre-event soil moisture conditions where each rainfall simulation consisted of a single 60 minute application of rainfall with constant intensity of about 76 mm/h. The results show runoff ratio, evaluated for different pre-event soil moisture conditions, ranging from 0 to 2% for B06 plot, and from 21 to 41% for B00. Runoff ratio for the recently burned plot was 60 times higher than for the plot burned six years before, under wet conditions, and 20 times higher, under very wet conditions. A large increase in sediment production also was measured in B00 plot, as compared with that in B06 plot. Suspended sediment yield from B00 plot was more than two orders of magnitude higher than that from B06 plot in all the simulated events. The high runoff and soil losses measured immediately after burning indicate that effective post-fire rehabilitation programs must be carried out to reduce flood risk and soil erosion in recently burned areas. However, the results for the plot burned six year prior show that recovery of the hydrological properties of the soil occurs after the transient post fire modification.

Relations between soil hydraulic properties and burn severity

Wildfire can affect soil hydraulic properties, often resulting in reduced infiltration. The magnitude of change in infiltration varies depending on the burn severity. Quantitative approaches to link burn severity with changes in infiltration are lacking. This study uses controlled laboratory measurements to determine relations between a remotely sensed burn severity metric (dNBR, change in normalised burn ratio) and soil hydraulic properties (SHPs). SHPs were measured on soil cores collected from an area burned by the 2013 Black Forest fire in Colorado, USA. Six sites with the same soil type were selected across a range of burn severities, and 10 random soil cores were collected from each site within a 30-m diameter circle. Cumulative infiltration measurements were made in the laboratory using a tension infiltrometer to determine field-saturated hydraulic conductivity, Kfs, and sorptivity, S. These measurements were correlated with dNBR for values ranging from 124 (low severity) to 886 (high severity). SHPs were related to dNBR by inverse functions for specific conditions of water repellency (at the time of sampling) and soil texture. Both functions had a threshold value for dNBR between 124 and 420, where Kfs and S were unchanged and equal to values for soil unaffected by fire. For dNBRs >~420, the Kfs was an exponentially decreasing function of dNBR and S was a linearly decreasing function of dNBR. These initial quantitative empirical relations provide a first step to link SHPs to burn severity, and can be used in quantitative infiltration models to predict post-wildfire infiltration and resulting runoff.

Pattern and profile of electric burn injury cases at a Burn centre.

Electrical burns are quite different from thermal and chemical burns. This study is from a centre which deals with job related electric burn injuries alone and thus can give a pure account of the electric burns and discuss the related peculiarities. Study aims to highlight the differences in the mechanism of electric burn injury, its mode of presentation, morbidity, complications and thus the treatment strategies as compared to rest of the burn injuries. This is a descriptive case series study of first consecutive 61 electric burn victims treated at a Burn Unit and Plastic Surgery centre. Cases were admitted and resuscitated at the emergency, and further treated at burn unit. Thorough history, examination findings and operative procedures were recorded. Patients were photographed for record as well. Emergency operative procedures, wound management, soft tissue coverage procedures and complications during the hospital stay were recorded and studied. Twenty cases (33%) were in the fifth decade of life. High voltage electric burn injury was seen in 42 (69%) of the cases. Whereas only 9 cases were treated conservatively, other 52 cases had 24 fasciotomies and 71 debridements. Series witnessed 10 expiries, and 22 amputations and all these were result of high voltage electric burns. Twenty eight soft tissue coverage procedures were carried out. Electric burn injuries are altogether different from rest of the burn injuries and must be treated accordingly. These injuries are peculiar for ongoing damage, extensive trauma, complications and prolonged morbidity. Treatment requires a high degree of suspicion, more aggressive management to unfold and minimize the deep seated insult.

Background In addition to forming the epithelial barrier against the outside environment keratinocytes are immunologically active cells. In the treatment of severely burned skin, cryoconserved keratinocyte allografts gain in importance. It has been proposed that these allografts accelerate wound healing also due to the expression of a favourable - keratinocyte-derived - cytokine and growth factor milieu. Methods In this study the morphology and cytokine expression profile of keratinocytes from skin after acute burn injury was compared to non-burned skin. Skin samples were obtained from patients after severe burn injury and healthy controls. Cells were cultured and secretion of selected inflammatory mediators was quantified using Bioplex Immunoassays. Immunohistochemistry was performed to analyse further functional and morphologic parameters. Results Histology revealed increased terminal differentiation of keratinocytes (CK10, CK11) in allografts from non-burned skin compared to a higher portion of proliferative cells (CK5, vimentin) in acute burn injury. Increased levels of IL-1α, IL-2, IL-4, IL-10, IFN-γ and TNFα could be detected in culture media of burn injury skin cultures. Both culture groups contained large amounts of IL-1RA. IL-6 and GM-CSF were increased during the first 15 days of culture of burned skin compared to control skin. Levels of VEGF, FGF-basic, TGF-ß und G-CSF were high in both but not significantly different. Cryoconservation led to a diminished mediator synthesis except for higher levels of intracellular IL-1α and IL-1ß. Conclusion Skin allografts from non-burned skin show a different secretion pattern of keratinocyte-derived cytokines and inflammatory mediators compared to keratinocytes after burn injury. As these secreted molecules exert auto- and paracrine effects and subsequently contribute to healing and barrier restoration after acute burn injury therapies affecting this specific cytokine/growth factor micromilieu could be

Global Burned Area and Biomass Burning Emissions from Small Fires

In several biomes, including croplands, wooded savannas, and tropical forests, many small fires occur each year that are well below the detection limit of the current generation of global burned area products derived from moderate resolution surface reflectance imagery. Although these fires often generate thermal anomalies that can be detected by satellites, their contributions to burned area and carbon fluxes have not been systematically quantified across different regions and continents. Here we developed a preliminary method for combining 1-km thermal anomalies (active fires) and 500 m burned area observations from the Moderate Resolution Imaging Spectroradiometer (MODIS) to estimate the influence of these fires. In our approach, we calculated the number of active fires inside and outside of 500 m burn scars derived from reflectance data. We estimated small fire burned area by computing the difference normalized burn ratio (dNBR) for these two sets of active fires and then combining these observations with other information. In a final step, we used the Global Fire Emissions Database version 3 (GFED3) biogeochemical model to estimate the impact of these fires on biomass burning emissions. We found that the spatial distribution of active fires and 500 m burned areas were in close agreement in ecosystems that experience large fires, including savannas across southern Africa and Australia and boreal forests in North America and Eurasia. In other areas, however, we observed many active fires outside of burned area perimeters. Fire radiative power was lower for this class of active fires. Small fires substantially increased burned area in several continental-scale regions, including Equatorial Asia (157%), Central America (143%), and Southeast Asia (90%) during 2001-2010. Globally, accounting for small fires increased total burned area by approximately by 35%, from 345 Mha/yr to 464 Mha/yr. A formal quantification of uncertainties was not possible, but sensitivity

Objective Tested the hypothesis that propranolol, a drug given to burn patients to reduce hypermetabolism/cardiac stress, may inhibit heat dissipation by changing the sensitivity of skin blood flow (SkBF) to local heating under neutral and hot conditions. Methods In a randomized double-blind study, a placebo was given to 8 burned children while propranolol was given to 13 burned children with similar characteristics (mean ± SD: 11.9±3y, 147±20cm, 45±23kg, 56±12% TBSA). Non-burned children (n=13, 11.4±3y, 152±15cm, 52±13kg) served as healthy controls. A progressive local heating protocol characterized SkBF responses in burned and unburned skin and non-burned control skin under the two environmental conditions (23°C and 34°C) via laser-Doppler flowmetry. Results Resting SkBF was greater in burned and unburned skin compared to the non-burned control (main effect: skin, P<0.0001; 57±32 burned; 38±36 unburned vs 9±8 control %SkBFmax). No difference was found for maximal SkBF capacity to local heating between groups. Additionally, dose response curves for the sensitivity of SkBF to local heating were not different among burned or unburned skin, and non-burned control skin (EC50, P>0.05) under either condition. Conclusion Therapeutic propranolol does not negatively affect SkBF under neutral or hot environmental conditions and further compromise temperature regulation in burned children. PMID:28071840

Burn injuries commonly occur in vulnerable age and social groups. Previous research has shown that frailty may represent a more important marker of adverse outcome in healthcare rather than chronological age (Roberts et al., 2012). In this paper we determined the relationship between burn injury, frailty, co-morbidities and long-term survival. Retrospective data collection from patients aged 75 with burns injuries, treated and discharged at Queen Victoria Hospital. The Clinical Frailty Scale (Rockwood et al., 2005) was used to calculate frailty at the time of admission. The expected mortality age (life expectancy) of deceased patients was obtained from two survival predictors. The data shows a statistically significant correlation between frailty score and complications and a statistically significant correlation between total body surface area percentage and complications. No significant difference was found between expected and observed age of death or life expectancy amongst the deceased (p value of 0.109). Based on the data from our unit, sustaining a burn as an elderly person does not reduce life expectancy. Medical and surgical complications, immediate, early and late, although higher with greater frailty and TBSA of burn, but do not adversely affect survival in this population.

Global warming is projected to increase the frequency and intensity of droughts in the Mediterranean region, as well as the occurrence of large fires. Understanding the interactions between drought, fire and plant responses is therefore important. In this study, we present an experiment in which rainfall patterns were modified to simulate various levels of drought in a Mediterranean shrubland of central Spain dominated by Cistus ladanifer, Erica arborea and Phillyrea angustifolia. A system composed of automatic rainout shelters with an irrigation facility was used. It was designed to be applied in vegetation 2 m tall, treat relatively large areas (36 m2), and be quickly dismantled to perform experimental burning and reassembled back again. Twenty plots were subjected to four rainfall treatments from early spring: natural rainfall, long-term average rainfall (2 months drought), moderate drought (25% reduction from long-term rainfall, 5 months drought) and severe drought (45% reduction, 7 months drought). The plots were burned in late summer, without interfering with rainfall manipulations. Results indicated that rainfall manipulations caused differences in soil moisture among treatments, leading to reduced water availability and growth of C. ladanifer and E. arborea in the drought treatments. However, P. angustifolia was not affected by the manipulations. Rainout shelters had a negligible impact on plot microenvironment. Experimental burns were of high fire intensity, without differences among treatments. Our system provides a tool to study the combined effects of drought and fire on vegetation, which is important to assess the threats posed by climate change in Mediterranean environments.

2015-08-01

An understanding of the perceived importance of a variety of factors affecting the ease of handling of sheep and the interactions between these factors is valuable in improving profitability and welfare of the livestock. Many factors may contribute to animal behaviour during handling, and traditionally these factors have been assessed in isolation under experimental conditions. A human social component to this phenomenon also exists. The aim of this study was to gain a deeper understanding of the importance of a variety of factors affecting ease of handling, and the interactions between these from the perspective of the livestock transporter. Qualitative interviews were used to investigate the factors affecting sheep behaviour during handling. Interview transcripts underwent thematic analysis. Livestock transporters discussed the effects of attitudes and behaviours towards sheep, helpers, facilities, distractions, environment, dogs and a variety of sheep factors including breed, preparation, experience and sex on sheep behaviour during handling. Transporters demonstrated care and empathy and stated that patience and experience were key factors determining how a person might deal with difficult sheep. Livestock transporters strongly believed facilities (ramps and yards) had the greatest impact, followed by sheep experience (naivety of the sheep to handling and transport) and breed. Transporters also discussed the effects of distractions, time of day, weather, dogs, other people, sheep preparation, body condition and sheep sex on ease of handling. The concept of individual sheep temperament was indirectly expressed.

Burns can be the most devastating injuries in the world, they constitute a global public health problem and cause widespread public health concern. Every year in Bangladesh more than 365,000 people are injured by electrical, thermal and other causes of burn injuries. Among them 27,000 need hospital admission and over 5600 people die. Immediate treatment and medication has been found to be significant in the success of recovering from a burn. However, common practices used in the treatment of burn injuries in the community is not well documented in Bangladesh. This study was designed to explore the perception of local communities in Bangladesh the common practices used and health-seeking behaviors sought immediately after a burn injury has occurred. A qualitative study was conducted using Focus Group Discussions (FGD) as the data collection method. Six unions of three districts in rural Bangladesh were randomly selected and FGDs were conducted in these districts with six burn survivors and their relatives and neighbours. Data were analyzed manually, codes were identified and the grouped into themes. The participants stated that burn injuries are common during the winter in Bangladesh. Inhabitants in the rural areas said that it was common practice, and correct, to apply the following to the injured area immediately after a burn: egg albumin, salty water, toothpaste, kerosene, coconut oil, cow dung or soil. Some also believed that applying water is harmful to a burn injury. Most participants did not know about any referral system for burn patients. They expressed their dissatisfaction about the lack of available health service facilities at the recommended health care centers at both the district level and above. In rural Bangladesh, the current first-aid practices for burn injuries are incorrect; there is a widely held belief that using water on burns is harmful.

Anthropogenic burning in dry dipterocarp forests (DDF) has become a common phenomenon throughout Thailand. It is feared that too frequent fires may affect vegetation structure and composition and thus impact on ecosystem productivity. The aim of this study was to quantify the effects of prescribed fires on sites with different past burning regimes on vegetation structure and composition in the Huay Kha Khaeng Wildlife Sanctuary (HKK), Thailand. Fire frequency was determined from satellite images and ranged from frequent, infrequent, rare and unburned with fire occurrences of 7, 2, 1 and 0 out of the past 10 years, respectively. The pre-burn fuel loads, the overstorey and understorey vegetation structure and composition were determined to investigate the effects of the contrasting past burning regimes. The burning experiment was carried out, applying a three-strip head-fire burning technique. The vegetation structure and composition were sampled again one year after the fire to assess the fire impacts. Aboveground fine fuel loads increased with the length of fire-free interval. The woody plant structures of the frequently burned stand differed from those of the other less frequently burned stands. The species composition of the overstorey on the frequently burned site, in particular that of small sized trees (4.5-10 cm dbh), also differed significantly from that of the other sites. Whilst the ground vegetation including shrubs and herbs did not differ between the past burning regimes, frequent burning obviously promoted the proliferation of graminoid vegetation. There was no clear evidence showing that the prescribed fires affected the mortality of trees (dbh> 4.5 cm) on the sites of the different past burning regimes. The effects of prescribed burning on the understorey vegetation structures varied between the past burning regimes and the understorey vegetation type. Therefore, it is recommended that the DDF at HKK should be subjected to a prescribed fire frequency

Fusarium spp are ubiquitous fungi recognized as opportunistic agents of human infections, and can produce severe infections in burn patients. The literature on Fusarium spp infections in pediatric burn patients is scarce. To describe the clinical and epidemiological features as well as outcome of Fusarium spp infections in pediatric burn patients. Retrospective, descriptive study of Fusarium spp infections in a specialized intensive care burn unit. In 15 patients Fusarium spp infections were diagnosed. Median age was 48 months. Direct fire injury was observed in ten patients. The median affected burn surface area was 45%. Twelve patients had a full thickness burn. Fourteen patients had a Garces Index ≥3. Fungal infection developed at a median of 11 days after burn injury. Fungi were isolated from burn wound in 14 patients and from the bone in one patient. Amphotericin B was the drug of choice for treatment followed by voriconazole. Median time of treatment completion was 23 days. One patient (7%) died of fungal infection-related causes. In our series Fusarium spp was an uncommon pathogen in severely burnt patients. The burn wound was the most common site of infection and mortality was low. Copyright © 2016 Elsevier Editora Ltda.

Economics of pediatric burns.

Sustaining a burn injury sets in motion a cycle of pain, disfigurement, and a search for survival. In pediatric burns, the injury extends to the parents where fear, ignorance, and helplessness forever change their lives. Pediatric burn injuries are caused by fire, hot liquids, clothing irons, hair curlers, caustic substances like drain cleaner, the grounding of an electrical source, and exposure to radiation. Efficiency in the delivery of pediatric burn care is critical. Maximizing resource utilization means continual self-evaluation and economic analysis of therapeutic modalities. Griffiths et al found that most childhood burns are due to scalds, which can be treated for $1061 per percent burn. Paddock et al reduced the cost of treating superficial pediatric burns and reduced the length of stay in hospital using silver-impregnated gauze over traditional methods. Barrett et al found improved cosmesis of skin grafts using cultured epithelial autografts but at a substantially increased cost. Corpron et al showed that pediatric burn units that treat burns >10% total body surface area and operative treatment of pediatric burns regardless of size generate positive revenue. There is a paucity of evidentiary pediatric burn economic data. More research is needed to address areas of pediatric burn care inefficiency. Improving knowledge of cost in all health care endeavors will create competition and drive down expenditures.

Comparing the reported burn conditions for different severity burns in porcine models: a systematic review.

PubMed

Andrews, Christine J; Cuttle, Leila

2017-12-01

There are many porcine burn models that create burns using different materials (e.g. metal, water) and different burn conditions (e.g. temperature and duration of exposure). This review aims to determine whether a pooled analysis of these studies can provide insight into the burn materials and conditions required to create burns of a specific severity. A systematic review of 42 porcine burn studies describing the depth of burn injury with histological evaluation is presented. Inclusion criteria included thermal burns, burns created with a novel method or material, histological evaluation within 7 days post-burn and method for depth of injury assessment specified. Conditions causing deep dermal scald burns compared to contact burns of equivalent severity were disparate, with lower temperatures and shorter durations reported for scald burns (83°C for 14 seconds) compared to contact burns (111°C for 23 seconds). A valuable archive of the different mechanisms and materials used for porcine burn models is presented to aid design and optimisation of future models. Significantly, this review demonstrates the effect of the mechanism of injury on burn severity and that caution is recommended when burn conditions established by porcine contact burn models are used by regulators to guide scald burn prevention strategies. © 2017 Medicalhelplines.com Inc and John Wiley & Sons Ltd.

Effects of Burning Alternative Fuel in a 5-Cup Combustor Sector

Tacina, K. M.; Chang, C. T.; Lee, C.-M.; He, Z.; Herbon, J.

2015-01-01

A goal of NASA's Environmentally Responsible Aviation (ERA) program is to develop a combustor that will reduce the NOx emissions and that can burn both standard and alternative fuels. To meet this goal, NASA partnered with General Electric Aviation to develop a 5-cup combustor sector; this sector was tested in NASA Glenn's Advanced Subsonic Combustion Rig (ASCR). To verify that the combustor sector was fuel-flexible, it was tested with a 50-50 blend of JP-8 and a biofuel made from the camelina sativa plant. Results from this test were compared to results from tests where the fuel was neat JP-8. Testing was done at three combustor inlet conditions: cruise, 30% power, and 7% power. When compared to burning JP-8, burning the 50-50 blend did not significantly affect emissions of NOx, CO, or total hydrocarbons. Furthermore, it did not significantly affect the magnitude and frequency of the dynamic pressure fluctuations.

We examined the effect of season of burn on flowering phenology of groundlayer species, in the year following burns, in a mesic-sand Midwestern oak savanna. Burn treatments were fall, early-season, growing-season, late-season, and 1 or 5 years after a prior early-season wildfire. For these treatments, we compared the number of flowering stems and of flowers for species overall, for the 20 most prolifically flowering species, as well as for species grouped by flowering phenoperiods, and by growth form. Growing-season burn had a significant negative effect on number of flowering stems and total number of flowers. This effect occurred when either the burn occurred during the flowering season or during the season prior to the flowering phenoperiod. Tradescantia ohiensis showed expedited flowering and Phlox pilosa showed delayed flowering in response to early-season burning. Flowering of early shrubs was reduced by the previous fall and early-spring fires, while flowering of mid-season blooming shrubs was reduced by the early- and growing-season burns. Vaccinium and Gaylussacia, early-flowering shrubs, produced fewer flowers 1 year after than 5 years after an early-season burn. Arabis lyrata showed reduced flowering from the early-season burn. We also found four instances where the early-spring burn effect on flowering was more severe than the fall burn effect, suggesting that many frequent early-season burns may be deleterious to flowering and reproduction of some species. Burns occurring too frequently in the same season could negatively affect future flowering and reproduction of these plant species.

The manual application of hot water or hot metal to an animal's skin surface is often used to prepare burn wound models. However, manual burn creation is subject to human variability. We developed a new device that can control the temperature, time, and pressure of contact to produce precise and reproducible animal burn wounds and investigated the conditions required to prepare various burn wounds using our new device. We prepared burn wounds on F344 rats using 3 contact times 2, 4, and 10 seconds using a stamp heated to 80°C. We observed the wound-healing process macroscopically and histologically and evaluated the burn depth using a laser speckle contrast-imaging device, which evaluated the blood flow of the wound. The changes in the burned area over time, tissue perfusion of the burn wounds, histological evaluation of the burn depth by hematoxylin-eosin and azocarmine and aniline blue staining, and the epithelialization rate (the ratio of the epithelialized area to the wound length) were evaluated on histological sections. Results indicated that the burn wounds prepared with contact times of 2, 4, and 10 seconds corresponded to superficial dermal burns, deep dermal burns, and full-thickness burns, respectively. We demonstrated that partial- and full-thickness burn wounds can be precisely and reproducibly created with our new automated burning device.

To present the experiences of nursing staff working with hospitalized burned children. Qualitative study. Data were obtained from semi-structured interviews applied to 16 people of the nursing team (12 professional technicians and 4) working at a burn treatment center. For the analysis, the Method information Interpretation of the Senses was used. The theoretical basis used to support the discussion of the study was proposed by Geertz's interpretive anthropology. The narratives showed that the process of care to burned children is stressful for the participants because they are psychologically involved with the tragic story of a patient who suffered burns, and therefore with the clinical situation. This allows for the development of empathy. On the other hand there cultural involvement facing and accepting the consequences of what happened to the patient, due to the change of body image stigma that the child will suffer hamper the re-socialization of the child after discharge. The nursing team is affected in various ways during the care of hospitalized burned children. There is need for educational programs for their preparation in the care of these patients.

Burns present a devastating injury to patients. Burns caused by chemical agents, present a worse scenario. In a resource limited country like Nigeria, readily available sources of these corrosive agents are mainly from lead-acid battery vendors and to some extent local small scale soap manufacturers who use caustic soda. We hypothesized that with the reduction in small scale soap manufacturing and increasing trend towards modernization in the use of dry cell batteries, chemical burns may be on the decline, and we sought to investigate this. The records of all acute burn patients seen at the Burns and Plastic Department of the National Orthopaedic Hospital Enugu Nigeria between January 2011 and December 2014 were retrospectively reviewed. The results were compared to similar studies carried out at the same centre. A questionnaire was administered to corrosive chemical (sulphuric and caustic soda) vendors to assess the trends in product sales and use in recent times. A total of 624 acute burn cases were treated during the period; among which, 12 cases (1.9%) were chemical burns. When compared with previous studies at the centre, Chemical burn cases were  recorded as the lowest rate. The median age of patients was 24 years. There were eight males and four females. Interpersonal assault was the commonest mechanism of injury with sulphuric acid suspected to be the commonest agent in 83.3% of the cases, while 16.7% of the cases were from accidental use of caustic soda. The head and neck as well as the upper limbs were the most affected (30%). Twenty-six questionnaires to lead-acid vendors were analyzed and revealed that all respondents noticed a marked downward trend in the sale of either sulphuric acid or caustic soda, and they attributed this to the ready availability of imported alternatives to locally manufactured soap or wet lead-acid batteries. Ease of use, durability and convenience of the dry cell batteries were cited as principal reasons. There appears to be

Burn injury is a devastating experience affecting all aspects of a person's essence, including his/her identity and perception. These patients require complex cognitive efforts to redefine their identity to deal with difficult condition after burn injury and preserve self-concept. The experience of life after burn injury is generally a solitary one, closely related to the patients' cultural and religious context. Therefore, this study was conducted aiming at investigating burn patients' experiences regarding how to preserve self-concept in life after burn injury in Iran. This qualitative study was carried out using qualitative content analysis and in-depth unstructured interviews with 17 surviving burn subjects. During the qualitative content analysis process, the concept of "locating" as the essence of the participants' experience was extracted as follows: (A) self-exploration (exploring the changes in one's life), (B) others' exploration (exploring the changes in the life of family members and the relationship between self and others), (C) position evaluation (self-position analysis), and (D) self-concept preservation. The present study has developed new understandings of mental experiences of burn patients' self-concept by describing the concept of "self-locating". It helps us in classifying and understanding the concepts described in comprehensive theories developed in this area. They do this by focusing on what burn patients experience for choosing self-preservation strategies and having a meaningful life. The finding can be used as a conceptual framework for palliative care program in Iran.

Scald burn, a preventable injury: Analysis of 4306 patients from a major tertiary care center.

Scalds have distinct epidemiological and predisposing risk factors amongst all types of burns. Though scald affects all age groups, the brunt falls on the minor age groups. It may result in major physical disabilities and significant loss of school years. Apart from the economic burden on family, major scald burn may compromise overall development of the affected children. Most of the scald injuries occur in domestic settings and are preventable. Despite improvement in living conditions, the incidence of scald burn has failed to decline. Our aim was to study the detailed epidemiology and severity of scald burn amongst all age groups. A retrospective study was carried out from the records of all burn patients who attended a tertiary burn care center from January 2013 and December 2014. Data of the patients with scald injury was segregated and analyzed using Microsoft excel spreadsheet. 10,175 burn patients attended the burn casualty during the study period, of which 42.3% had sustained scald. 56.85% of patients were under 15 years of age with preschool children (36.4%) being the prime victims of scald. The % TBSA involved is also relatively larger in children. Scald follows definite seasonal variation peaking in winters. 36.8% patients arrived to the hospital without any first aid. 74.2% of patients reported to casualty with in 24hours after sustaining scald injury. The median time interval between injury and reporting to casualty was 3hours 30minutes. This study concludes that the scald is injury of all age groups, though majority of them are children. The first aid is not given to large number of patients and late reporting is quite common. These are the factors which may affect the course of scald burn. Spreading public awareness regarding safe household practises and educating them for proper first aid management after scald may have significant impact on the burden of care and outcome.

Atmospheric pollution and global warming issues are increasingly becoming major environmental concerns. Fire is one of the significant sources of pollutant gases released into the atmosphere; and tropical biomass fires, which are of particular interest in this study, contribute greatly to the global budget of CO and CO2. This pioneer research simulates the natural biomass burning strategy in Malaysia using an experimental burning facility. The investigation was conducted on the emissions (CO2, CO, and Benzene, Toluene, Ethylbenzene, Xylenes (BTEX)) from ten tropical biomass species. The selected species represent the major tropical forests that are frequently subjected to dry forest fire incidents. An experimental burning facility equipped with an on-line gas analyzer was employed to determine the burning emissions. The major emission factors were found to vary among the species, and the specific results were as follows. The moisture content of a particular biomass greatly influenced its emission pattern. The smoke analysis results revealed the existence of BTEX, which were sampled from a combustion chamber by enrichment traps aided with a universal gas sampler. The BTEX were determined by organic solvent extraction followed by GC/MS quantification, the results of which suggested that the biomass burning emission factor contributed significant amounts of benzene, toluene, and m,p-xylene. The modified combustion efficiency (MCE) changed in response to changes in the sample moisture content. Therefore, this study concluded that the emission of some pollutants mainly depends on the burning phase and sample moisture content of the biomass. Copyright © 2015. Published by Elsevier B.V.

No evidence of infection or exposure to Highly Pathogenic Avian Influenzas in peridomestic wildlife on an affected poultry facility

2017-01-01

We evaluated the potential transmission of avian influenza viruses (AIV) in wildlife species in three settings in association with an outbreak at a poultry facility: 1) small birds and small mammals on a poultry facility that was affected with highly pathogenic AIV (HPAIV) in April 2015; 2) small birds and small mammals on a nearby poultry facility that was unaffected by HPAIV; and 3) small birds, small mammals, and waterfowl in a nearby natural area. We live-captured small birds and small mammals and collected samples from hunter-harvested waterfowl to test for active viral shedding and evidence of exposure (serum antibody) to AIV and the H5N2 HPAIV that affected the poultry facility. We detected no evidence of shedding or specific antibody to AIV in small mammals and small birds 5 mo after depopulation of the poultry. We detected viral shedding and exposure to AIV in waterfowl and estimated approximately 15% viral shedding and 60% antibody prevalence. In waterfowl, we did not detect shedding or exposure to the HPAIV that affected the poultry facility. We also conducted camera trapping around poultry carcass depopulation composting barns and found regular visitation by four species of medium-sized mammals. We provide preliminary data suggesting that peridomestic wildlife were not an important factor in the transmission of AIV during the poultry outbreak, nor did small birds and mammals in natural wetland settings show wide evidence of AIV shedding or exposure, despite the opportunity for exposure.

Specific burn outcome prediction scores such as the Abbreviated Burn Severity Index (ABSI), Ryan, Belgian Outcome of Burn Injury (BOBI) and revised Baux scores have been extensively studied. Validation studies of the critical care score SAPS II (Simplified Acute Physiology Score) have included burns patients but not addressed them as a cohort. The study aimed at comparing their performance in a Swiss burns intensive care unit (ICU) and to observe whether they were affected by a standardized definition of inhalation injury. We conducted a retrospective cohort study, including all consecutive ICU burn admissions (n=492) between 1996 and 2013: 5 epochs were defined by protocol changes. As required for SAPS II calculation, stays <24h were excluded. Data were collected on age, gender, total body surface area burned (TBSA) and inhalation injury (systematic standardized diagnosis since 2006). Study epochs were compared (χ2 test, ANOVA). Score performance was assessed by receiver operating characteristic curve analysis. SAPS II performed well (AUC 0.89), particularly in burns <40% TBSA (AUC 0.93). Revised Baux and ABSI scores were not affected by the standardized diagnosis of inhalation injury and showed the best performance (AUC 0.92 and 0.91 respectively). In contrast, the accuracy of the BOBI and Ryan scores was lower (AUC 0.84 and 0.81) and reduced after 2006. The excellent predictive performance of the classic scores (revised Baux score and ABSI) was confirmed. SAPS II was nearly as accurate, particularly in burns <40% TBSA. Ryan and BOBI scores were least accurate, as they heavily weight inhalation injury.

2005-01-01

In this study, we sought to test the medical efficacy of a Chinese medical herb product, moist exposed burn ointment (MEBO), on wound healing rate and infection control in burn injury. Standardized deep burn wounds were created on the back skin of rats by applying a hot brass bar for 12 to 18 seconds. MEBO was applied four times per day and compared with petroleum jelly, silver sulfadiazine, and dry exposure therapy. Under such a controlled setting, although MEBO had a better wound healing rate than the dry exposure treatment, it did not show the medical advantage statistically, as has been claimed, over the other two treatments (P > .05), either in terms of wound healing rate or bacterial control. We conclude that the MEBO is not suitable for deep burn wound treatment, particularly when infection is a concern.

2017-03-01

To develop a comprehensive definition to identify work-related burns in the National Burn Repository (NBR) based on multiple fields and describes injuries by occupation. The NBR, which is an inpatient dataset, was used to compare type and severity of burn injuries by occupation. Using the definition developed for this analysis, 22,969 burn injuries were identified as work-related. In contrast, the single work-related field intended to capture occupational injuries only captured 4696 cases. The highest numbers of burns were observed in construction/extraction, food preparation, and durable goods production occupations. Occupations with a mean total body surface area (TBSA) burned greater than 10% include transportation and material-moving, architecture and engineering, and arts/design/entertainment/sports/media occupations. The NBR dataset should be further utilized for occupational burn injury investigations and multiple fields should be considered for case ascertainment.
