  1. Arrhenius Rate: constant volume burn

    Energy Technology Data Exchange (ETDEWEB)

    A constant volume burn occurs for an idealized initial state in which a large volume of reactants at rest is suddenly raised to a high temperature and begins to burn. Due to the uniform spatial state, there is no fluid motion and no heat conduction. This reduces the time evolu tion to an ODE for the reaction progress variable. With an Arrhenius reaction rate, two characteristics of thermal ignition are illustrated: induction time and thermal runaway. The Frank-Kamenetskii approximation then leads to a simple expression for the adiabatic induction time. For a first order reaction, the analytic solution is derived and used to illustrate the effect of varying the activation temperature; in particular, on the induction time. In general, the ODE can be solved numerically. This is used to illustrate the effect of varying the reaction order. We note that for a first order reaction, the time evolution of the reaction progress variable has an exponential tail. In contrast, for a reaction order less than one, the reaction completes in a nite time. The reaction order also affects the induction time.

  3. High Pressure Burn Rate Measurements on an Ammonium Perchlorate Propellant

    High pressure deflagration rate measurements of a unique ammonium perchlorate (AP) based propellant are required to design the base burn motor for a Raytheon weapon system. The results of these deflagration rate measurements will be key in assessing safety and performance of the system. In particular, the system may experience transient pressures on the order of 100's of MPa (10's kPSI). Previous studies on similar AP based materials demonstrate that low pressure (e.g. P < 10 MPa or 1500 PSI) burn rates can be quite different than the elevated pressure deflagration rate measurements (see References and HPP results discussed herein), hence elevated pressure measurements are necessary in order understand the deflagration behavior under relevant conditions. Previous work on explosives have shown that at 100's of MPa some explosives will transition from a laminar burn mechanism to a convective burn mechanism in a process termed deconsolidative burning. The resulting burn rates that are orders-of-magnitude faster than the laminar burn rates. Materials that transition to the deconsolidative-convective burn mechanism at elevated pressures have been shown to be considerably more violent in confined heating experiments (i.e. cook-off scenarios). The mechanisms of propellant and explosive deflagration are extremely complex and include both chemical, and mechanical processes, hence predicting the behavior and rate of a novel material or formulation is difficult if not impossible. In this work, the AP/HTPB based material, TAL-1503 (B-2049), was burned in a constant volume apparatus in argon up to 300 MPa (ca. 44 kPSI). The burn rate and pressure were measured in-situ and used to calculate a pressure dependent burn rate. In general, the material appears to burn in a laminar fashion at these elevated pressures. The experiment was reproduced multiple times and the burn rate law using the best data is B = (0.6 {+-} 0.1) x P{sup (1.05{+-}0.02)} where B is the burn

  4. Accuracy of real time radiography burning rate measurement

    The design of a solid propellant rocket motor requires the determination of a propellant's burning-rate and its dependency upon environmental parameters. The requirement that the burning-rate be physically measured, establishes the need for methods and equipment to obtain such data. A literature review reveals that no measurement has provided the desired burning rate accuracy. In the current study, flash x-ray modeling and digitized film-density data were employed to predict motor-port area to length ratio. The pre-fired port-areas and base burning rate were within 2.5% and 1.2% of their known values, respectively. To verify the accuracy of the method, a continuous x-ray and a solid propellant rocket motor model (Plexiglas cylinder) were used. The solid propellant motor model was translated laterally through a real-time radiography system at different speeds simulating different burning rates. X-ray images were captured and the burning-rate was then determined. The measured burning rate was within 1.65% of the known values.

    Partial-thickness scalds are the most common pediatric burn injury, and primary management consists of wound dressings to optimize the environment for reepithelialization. Operative intervention is reserved for burns that fail to heal using conservative methods. Worldwide, paraffin-based gauze (Jelonet) is the most common burn dressing; but literature suggests that it adheres to wounds and requires more frequent dressing change that may traumatize newly epithelialized surfaces. Hydrocolloid dressings (DuoDERM) provide an occlusive moist environment to optimize healing and are associated with less frequent dressing changes. The aim of the study was to retrospectively analyze pediatric burns in a single tertiary referral center over a 10-year period comparing the impact of Jelonet and DuoDERM dressings relative to operative intervention rates. All pediatric burns admitted between 1997 and 2007 were identified using the Hospital Inpatient Enquiry system. Demographics were collected from hospital records and theater logbooks. Acute, partial-thickness burns in patients younger than 15 years were analyzed according to dressing type applied (Jelonet or DuoDERM). Two hundred forty-eight pediatric burns were analyzed between 1997 and 2007. One hundred thirty-nine patients were treated with Jelonet dressings, and 109 were treated with DuoDERM. Debridement and grafting were required in 60 (43%) of the Jelonet patients compared with 10 (9%) of the DuoDERM patients (P pediatric burns.

  10. Resistance of the boreal forest to high burn rates.

    Boreal ecosystems and their large carbon stocks are strongly shaped by extensive wildfires. Coupling climate projections with records of area burned during the last 3 decades across the North American boreal zone suggests that area burned will increase by 30-500% by the end of the 21st century, with a cascading effect on ecosystem dynamics and on the boreal carbon balance. Fire size and the frequency of large-fire years are both expected to increase. However, how fire size and time since previous fire will influence future burn rates is poorly understood, mostly because of incomplete records of past fire overlaps. Here, we reconstruct the length of overlapping fires along a 190-km-long transect during the last 200 y in one of the most fire-prone boreal regions of North America to document how fire size and time since previous fire will influence future fire recurrence. We provide direct field evidence that extreme burn rates can be sustained by a few occasional droughts triggering immense fires. However, we also show that the most fire-prone areas of the North American boreal forest are resistant to high burn rates because of overabundant young forest stands, thereby creating a fuel-mediated negative feedback on fire activity. These findings will help refine projections of fire effect on boreal ecosystems and their large carbon stocks.

    Full Text Available Hospital acquired infections (HAIs are the major contributors of mortality associated with burn injuries. The aim of this research was to document the antecedents affiliated with major burn injuries, hospitalization and mortality in burn patients. We performed a single center prospective study of patients admitted during 3 months period (April-June 2014 in burn wards of government hospital. There were 100 patients in this investigation which were observed weekly. The inclusion criterion was based on the shifting of patients from emergency to the wards after initial treatment of more than 24 h. Variables included were age and gender of the patient, the percent total body surface area (%TBSA burn, the cause of the burn. Mean age of patients was 30.29 years. More females (55.67% were admitted than males (44.32%. The total body surface area (%TBSA burnt were from 15%- 95% respectively moreover children were more sensitive to hospital acquired infections (HAIs and mortality rate was 34% in children with mean age of 5 years and disability of body parts were 42% among 75% were females. Whereas the most common (HAIs were primary blood stream (PBS with mean value of 30.50, wound infections (WIS were at second prevalence with mean value of 27.50, followed by sepsis (S and pneumonia (P 10.33, eye infections (EIs 4.833 and urinary tract infections (UTIs 2.667. Factors significantly (p-value= 0.000 associated with increased duration of hospitalization caught HAIs mortality include the age and gender of the patient, the cause of burn, inhalation injury, the region affected and %TBSA burnt. It concluded that the mortality was very much dependent on age and gender of the patient, burn causes, affected area as well as %TBSA burnt are considerable factors in determining the relationship of HAIs and whether the patients will survive or knuckle to injuries.

    Carbon burning is a critical phase for nucleosynthesis in massive stars. The conditions for igniting this burning stage, and the subsequent isotope composition of the resulting ashes, depend strongly on the reaction rate for 12C+12C fusion at very low energies. Results for the cross sections for this reaction are influenced by various backgrounds encountered in measurements at such energies. In this paper, we report on a new measurement of 12C+12C fusion cross sections where these backgrounds have been minimized. It is found that the astrophysical S factor exhibits a maximum around Ecm=3.5 -4.0 MeV, which leads to a reduction of the previously predicted astrophysical reaction rate.

    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.

    Skin grafting is a simple and common procedure for achieving wound closure. Despite its widespread use, there is little objective information about the outcomes of skin-grafted burn wounds. The purposes of this study were to determine the length of time it takes to achieve complete wound healing in split-thickness skin-grafted burn wounds and to identify factors that affect time to complete wound healing. The authors prospectively collected information from January through September of 2003 on 52 consecutive patients. Time to complete wound healing was defined as the number of days from burn wound skin grafting until the wound was 100 percent epithelialized. Percentage of total body surface area burned, preoperative prealbumin level, sex, age, graft type, burn mechanism, cause of graft loss, and presence of hypergranulation tissue were assessed and correlated with time to complete wound healing. The time to complete wound healing ranged from 2 to 75 days. Forty-six percent of skin grafts had 100 percent wound closure at postoperative day 7. No grafts were lost to infection. Factors that significantly affected time to complete wound healing were graft loss by seroma, preoperative prealbumin level, presence of hypergranulation tissue, and burns caused by hot solids. The authors' results suggest that most patients will heal skin-grafted burn wounds within 2 weeks. Meticulous attention to prevention of seroma, hypergranulation tissue formation, and malnutrition might decrease time to complete wound healing. Factors thought to influence time to complete wound healing, such as total body surface area burned, sex, age, graft type, and infection, did not significantly affect the authors' patient group.

    Full Text Available Copper chromites are well known as burning rate catalysts for the combustion of composite solid propellants, used as a source of energy for rocket propulsion. The propellant burning rate depends upon the catalyst characteristics such as chemical composition and specific surface area. In this work, copper chromite samples from different suppliers were characterized by chemical analysis, FT-IR spectroscopy and by surface area measurement (BET. The samples were then evaluated as burning rate catalyst in a typical composite propellant formulation based on HTPB binder, ammonium perchlorate and aluminum. The obtained surface area values are very close to those informed by the catalyst suppliers. The propellant processing as well as its mechanical properties were not substantially affected by the type of catalyst. Some copper chromite catalysts caused an increase in the propellant burning rate in comparison to the iron oxide catalyst. The results show that in addition to the surface area, other parameters like chemical composition, crystalline structure and the presence of impurities might be affecting the catalyst performance. All evaluated copper chromite samples may be used as burning rate catalyst in composite solid propellant formulations, with slight advantages for the SX14, Cu-0202P and Cu-1800P samples, which led to the highest burning rate propellants.

    The nucleosynthesis of light elements, from helium up to silicon, mainly occurs in Red Giant and Asymptotic Giant Branch stars and Novae. The relative abundances of the synthesized nuclides critically depend on the rates of the nuclear processes involved, often through non-trivial reaction chains, combined with complex mixing mechanisms. In this paper, we summarize the contributions made by LUNA experiments in furthering our understanding of nuclear reaction rates necessary for modeling nucleosynthesis in AGB stars and Novae explosions.

    current situation; satellite data indicates that the majority of savannas have not burned in the past 10 yr, even in Africa, which is considered "the burning continent". Although we have not considered increased charcoal burning or changes in OH concentrations as potential causes for the elevated CO concentrations found at SPO, it is unlikely they can explain the large increase found in the CO concentrations in ice core data. Confirmation of the CO ice core data would therefore call for radical new thinking about causes of variable global fire rates over recent centuries.

    Background: Burn injuries are one of the main causes of mortality and morbidity throughout the world and burn patients have higher chances for infection due to their decreased immune resistance. Levamisole, as an immunomodulation agent, stimulates the immune response against infection. Materials and Methods: This randomized clinical trial was conducted in Motahari Burn Center, Tehran, Iran. Patients who had second- or third-degree burn with involvement of more than 50% of total body surface area (TBSA) were studied. The levamisole group received levamisole tablet, 100 mg per day. Meantime, both the levamisole and control groups received the standard therapy of the Burn Center, based on a standard protocol. Then, the outcome of the patients was evaluated. Results: 237 patients entered the study. After excluding 42 patients with inhalation injury, electrical and chemical burns, and the patients who died in the first 72 h, 195 patients remained in the study, including 110 patients in the control group and 85 in the treatment group. The mean age of all patients (between 13 to 64 years) was 33.29 ± 11.39 years (Mean ± SD), and it was 33.86 ± 11.45 years in the control group and 32.57 ± 11.32 years in the treatment group. The mean percentage of TBSA burn was 64.50 ± 14.34 and 68.58 ± 14.55 for the levamisole and control groups, respectively, with the range of 50-100% and 50-95% TBSA. The mortality rate was 68 (61.8%) patients in the control group and 50 (58.8%) patients in the treatment group (P = 0.8). Conclusion: According to this study, there was no significant relationship between improvement of mortality and levamisole consumption. PMID:24381625

    Oxygen enrichment of room air is an effective way to resist hypoxia at high altitude, but it may introduce a potential fire hazard. In common, the burning rate of light and thin homogeneous solid in oxygen enriched atmosphere was used to assess the fire hazard. For the purpose of measuring the burning rate of light and thin homogeneous solid in oxygen enriched atmosphere, we used the methods of laser contact ignition and direct calculation of burning rate, and invented a device that includes mixing gas system, ignition equipment, system of measuring the burning rate and self-made specimen frame. By using the homemade device, we studied the burning rate of filter paper under low pressure and in oxygen-enriched atmosphere and in that of the oxygen concentration of reached stationary burning rate. The results showed that this device was simple, and could obtain the burning rate of light and thin homogeneous solid quantitatively.

    Full Text Available Burn injuries are important in terms of causing serious disability and threatening life. With the establishment of modern burn treatment units and advances in acute care management contributed to a reduced mortality rate over the last decades. As a result of improved outcome, more attention has to be given to a comprehensive burn rehabilitation program. Burn rehabilitation is a process that starts from day of admission and continues for months or sometimes years after the initial event. The term ‘burn rehabilitation’ incorporates the physical, physiological and social aspects of care. Burns can leave a patient with severely debilitating and deforming contractures, which can lead to significant disability when left untreated. Burn rehabilitation aims to prevent the possible complications, minimalize joint contractures and deformities, increase range of motion, control hypertrophic scarring, achieve the best possible functional capacity and to regain the patients vocational and recreational activities.

    In burned forestlands, fire scar wounds commonly occur on tree stems as a result of cambial heating. In hardwood forests in particular, wounding can lead to stem decay with the extent of decay being related to scar size and exposure time. Therefore, wound closure rates are important to understand in the context of fire management such that allowing sufficient time for...

    Context. The NO cycle takes place in the deepest layer of a H-burning core or shell, when the temperature exceeds T ≃ 30 × 106 K. The O depletion observed in some globular cluster giant stars, always associated with a Na enhancement, may be due to either a deep mixing during the red giant branch (RGB) phase of the star or to the pollution of the primordial gas by an early population of massive asymptotic giant branch (AGB) stars, whose chemical composition was modified by the hot bottom burning. In both cases, the NO cycle is responsible for the O depletion. Aims: The activation of this cycle depends on the rate of the 15N(p, γ)16O reaction. A precise evaluation of this reaction rate at temperatures as low as experienced in H-burning zones in stellar interiors is mandatory to understand the observed O abundances. Methods: We present a new measurement of the 15N(p, γ)16O reaction performed at LUNA covering for the first time the center of mass energy range 70-370 keV, which corresponds to stellar temperatures between 65 × 106 K and 780 × 106 K. This range includes the 15N(p, γ)16O Gamow-peak energy of explosive H-burning taking place in the external layer of a nova and the one of the hot bottom burning (HBB) nucleosynthesis occurring in massive AGB stars. Results: With the present data, we are also able to confirm the result of the previous R-matrix extrapolation. In particular, in the temperature range of astrophysical interest, the new rate is about a factor of 2 smaller than reported in the widely adopted compilation of reaction rates (NACRE or CF88) and the uncertainty is now reduced down to the 10% level.

    The purposes of this pilot study were to measure pain associated with dressing changes, assess the presence of infection, and document healing times of burn-injured Amish in central Ohio using an herbal therapy consisting of Burns and Wounds™ ointment (B&W) and burdock (Arctium ssp.) leaves. B&W contains honey, lanolin, olive oil, wheat germ oil, marshmallow root, Aloe vera gel, wormwood, comfrey root, white oak bark, lobelia inflata, vegetable glycerin, bees wax, and myrrh. A prospective, case series design guided the study within a community-based participatory research framework. Amish burn dressers provided burn care. Registered nurses monitored each case and documented findings. Pain scores were noted and burns were inspected for infection during dressing changes; healing times were measured from day of burn to complete closure of the skin. All cases were photographed. Between October 2011 and May 2013, five Amish were enrolled. All had first- and second-degree burns. B&W/burdock leaf dressing changes caused minimal or no pain; none of the burns became infected, and healing times averaged less than 14 days. The use of this herbal remedy appears to be an acceptable alternative to conventional burn care for these types of burns. The trauma of dressing changes was virtually nonexistent. Nurses working in communities with Amish residents should be aware of this herbal-based method of burn care and monitor its use when feasible. © The Author(s) 2014.

  19. Metal vapor condensation under high pressure (mercury vapor to 500 psia). [Heat transfer coefficients

    1975-01-01

    Mercury vapor up to 500 psia was condensed outside a cylindrical tube in both horizontal and vertical positions. Results show consistently low heat transfer coefficients compared to Nusselt's theory. Two auxiliary mercury vapor condensers downstream of the boiler vent were used to control and safeguard the system. Constantan wires were spot welded on the surface inside the test condenser tube. The heat flux ranged from 20,000 to 45,000 Btu/h-ft/sup 2/ and the temperature differences between vapor and condensing wall from 6 to 50/sup 0/F. The condensation heat transfer coefficients, ranging from 850 to 3,500 Btu/h-/sup 0/F-ft/sup 2/, are only about 3 to 9 percent of those predicted by Nusselt's theory. Due to the positive pressure in the system for most test runs, the chance of any in-leakage of noncondensable gases into the boiler is extremely small. Since no substantial change of heat transfer rate resulted from wide variations in the heat load on the reflux condenser at some specific heat flux on the test condenser tube, the low heat transfer rate of mercury vapor condensation was not due to the presence of any non-condensable gas. The test data for high vapor pressure up to 500 psia reveal that the heat transfer coefficient is independent of the vapor pressure level. The condensation coefficients calculated based on kinetic theory are much smaller than unity and decreasewith vapor pressure. It is hypothesized that dimer content in the metal vapor phase might behave as non-condensable or semi-condensable gas and create a diffusional barrier at the vapor-liquid interface near the condensate film. This dimer vapor could be the main cause of interfacial resistance during metal vapor condensation process. 41 figures, 7 tables, 58 references. (DLC)

  20. Convective Heat Transfer Scaling of Ignition Delay and Burning Rate with Heat Flux and Stretch Rate in the Equivalent Low Stretch Apparatus

    Olson, Sandra

    2011-01-01

    To better evaluate the buoyant contributions to the convective cooling (or heating) inherent in normal-gravity material flammability test methods, we derive a convective heat transfer correlation that can be used to account for the forced convective stretch effects on the net radiant heat flux for both ignition delay time and burning rate. The Equivalent Low Stretch Apparatus (ELSA) uses an inverted cone heater to minimize buoyant effects while at the same time providing a forced stagnation flow on the sample, which ignites and burns as a ceiling fire. Ignition delay and burning rate data is correlated with incident heat flux and convective heat transfer and compared to results from other test methods and fuel geometries using similarity to determine the equivalent stretch rates and thus convective cooling (or heating) rates for those geometries. With this correlation methodology, buoyant effects inherent in normal gravity material flammability test methods can be estimated, to better apply the test results to low stretch environments relevant to spacecraft material selection.

    A hybrid closed bomb-strand burner is used to measure the burning behavior of the titanium subhydride potassium perchlorate pyrotechnic with an equivalent hydrogen concentration of 1.65. This experimental facility allows for simultaneous measurement of the closed bomb pressure rise and pyrotechnic burn rate as detected by electrical break wires over a range of pressures. Strands were formed by pressing the pyrotechnic powders to bulk densities between 60% and 90% theoretical maximum density. The burn rate dependance on initial density and vessel pressure are measured. At all initial strand densities, the burn is observed to transition from conductive to convective burning within the strand. The measured vessel pressure history is further analyzed following the closed bomb analysis methods developed for solid propellants.

    In case of double-base properants, the temperature sensitivity of burning rate for this type of propellants having higher energy becomes smaller than that of propellants having lower energy. When the energy contained in propellants increases, or initial propellant temperatures increase, the burning surface temperature of propellant increases, therefore, the reaction in fizz zone is accelerated, the dark zone temperature increases, and the temperature gradient in fizz zone increases. This increase of temperature gradient increases the burning rate of propellant. In case of HMX-CMDB propellants, when the energy contained in propellants increases, or initial propellant temperatures decrease, the burning surface temperature of propellant decreases, therefore, the reaction in fizz zone is decelerated, the dark zone temperature decreases, and the temperature gradient in fizz zone decreases. This decrease of temperature gradient decreases the burning rate of propellant. As a result, it was clarified that the temperatures as common physical properties which had an effect of initial propellant temperatures on the burning rates were the burning surface temperature and the dark zone temperature. 22 refs., 12 figs., 2 tabs.

  3. Effect of Air Staging Ratios on the Burning Rate and Emissions in an Underfeed Fixed-Bed Biomass Combustor

    Directory of Open Access Journals (Sweden)

    2016-11-01

    Full Text Available This experimental work studies a small-scale biomass combustor (5–12 kW with an underfed fixed bed using low air staging ratios (15%–30%. This document focuses on the influence of the operative parameters on the combustion process, so gaseous emissions and the distribution and concentration of particulate matter have also been recorded. The facility shows good stability and test repeatability. For the studied airflow ranges, the results show that increasing the total airflow rate does not increase the overall air excess ratio because the burning rate is proportionally enhanced (with some slight differences that depend on the air staging ratio. Consequently, the heterogeneous reactions at the bed remain in the so-called oxygen-limited region, and thus the entire bed operates under sub-stoichiometric conditions with regards of the char content of the biomass. In addition, tests using only primary air (no staging may increase the fuel consumption, but in a highly incomplete way, approaching a gasification regime. Some measured burning rates are almost 40% higher than previous results obtained in batch combustors due to the fixed position of the ignition front. The recorded concentration of particulate matter varies between 15 and 75 mg/Nm3, with a main characteristic diameter between 50 and 100 nm.

    Session-rating of perceived exertion (RPE) is a method frequently utilised in exercise and sports science to quantify training load of an entire aerobic exercise session. It has also been demonstrated that session-RPE is a valid and reliable method to quantify training load during resistance exercise, in healthy and athletic populations. This study aimed to investigate the effectiveness of session-RPE as a method to quantify exercise intensity during resistance training in patients with acute burns. Twenty burns patients (mean age=31.65 (±10.09) years), with a mean TBSA of 16.4% (range=6-40%) were recruited for this study. Patients were randomly allocated to the resistance training (n=10) or control group (n=10). All patients completed a four week resistance training programme. Training load (session-RPE×session duration), resistance training session-volume and pre-exercise pain were recorded for each exercise session. The influence of; age, gender, %TBSA, exercise group (resistance training vs. control), pre-exercise pain, resistance training history and session-volume on training load were analysed using a multilevel mixed-effects linear regression. Session-volume did not influence training load in the final regression model, however training load was significantly greater in the resistance training group, compared with the control group (ptraining load, where increasing pain was associated with a higher session-RPE (p=0.004). Further research is indicated to determine the exact relationship between pain, resistance training history, exercise intensity and session-RPE and training load before it can be used as a method to monitor and prescribe resistance training load in acute burns patients.

    In order to improve predictions for the burning efficiency and the residue composition of in-situ burning of crude oil, the burning mechanism of crude oil was studied in relation to the composition of its hydrocarbon mixture, before, during and after the burning. The surface temperature, flame...... to the predictions of four conceptual models that describe the burning mechanism of multicomponent fuels. Based on the comparisons, hydrocarbon liquids were found to be best described by the Equilibrium Flash Vaporization model, showing a constant gas composition and gasification rate. The multicomponent fuels...... followed the diffusion-limited gasification model, showing a change in the hydrocarbon composition of the fuel and its evaporating gases, as well as a decreasing gasification rate, as the burning progressed. This burning mechanism implies that the residue composition and burning efficiency mainly depend...

    Full Text Available Nano-catalysts containing copper–cobalt oxides (Cu–Co–O have been synthesized by the citric acid (CA complexing method. Copper (II nitrate and Cobalt (II nitrate were employed in different molar ratios as the starting reactants to prepare three types of nano-catalysts. Well crystalline nano-catalysts were produced after a period of 3 hours by the calcination of CA–Cu–Co–O precursors at 550 °C. The phase morphologies and crystal composition of synthesized nano-catalysts were examined using Scanning Electron Microscope (SEM, Energy Dispersive Spectroscopy (EDS and Fourier Transform Infrared Spectroscopy (FTIR methods. The particle size of nano-catalysts was observed in the range of 90 nm–200 nm. The prepared nano-catalysts were used to formulate propellant samples of various compositions which showed high reactivity toward the combustion of HTPB/AP-based composite solid propellants. The catalytic effects on the decomposition of propellant samples were found to be significant at higher temperatures. The combustion characteristics of composite solid propellants were significantly improved by the incorporation of nano-catalysts. Out of the three catalysts studied in the present work, CuCo-I was found to be the better catalyst in regard to thermal decomposition and burning nature of composite solid propellants. The improved performance of composite solid propellant can be attributed to the high crystallinity, low agglomeration and lowering the decomposition temperature of oxidizer by the addition of CuCo-I nano-catalyst.

    Burning rate and specific impulse of a solid propellant are extremely important parameters in a design of a solid rocket motor. In this study, the relations between the burning rate and the amount of energy contained in HMX-CMDB propellants wherein the amount of energy is varied by adding HMX (High Melting Point Explosive). The following results are obtained. The final flame temperature is getting higher when the amount of energy is increased by adding HMX into a double-base propellant. The higher the final flame temperature is, the lower the burning rate is. Dark zone temperature, as a physical property, is lowered when the containing amount of energy is increased by adding HMX into the double-base propellant. This is because that, when weight fraction of HMX is increased, reaction heat at burning surface decreases, and the reaction in fizz zone is getting slower. The higher the dark zone temperature is, the higher the burning rate is. 20 refs., 11 figs., 1 tab.

    We present incremental slip rate and paleo-earthquake data from the Conway segment of the eastern Hope fault, within the Marlborough Fault System (MFS) in the northern South Island of New Zealand. Our incremental slip rate site at Hossack Station is located near the western boundary of the Conway segment (near the Hanmer pull-apart basin), and preserves four offsets of the Hossack Stream channel that range in size from c. 11 to 190 m. Channel cut and fill deposits were exposed in several fault-parallel (channel perpendicular) trenches, and the initiation and abandonment of these offset channels are constrained by >60 radiocarbon ages, yielding four incremental slip rates spanning the Holocene. Our paleoseismologic trench at Green Burn, at the eastern end of the Conway segment near Kaikoura, was excavated across the 5-m-high fault scarp into the adjacent bog deposits. This fault-perpendicular trench revealed evidence for at least four paleo-earthquakes with age constraints provided by >40 radiocarbon dates. These results add to a growing body of slip rate and paleo-earthquake age and displacement data from all four main strike-slip faults that comprise the MFS. Collectively, these observations from the Hope fault are beginning to reveal the detailed system-level behavior of the four main faults in the MFS, with fundamental implications for, among other things, earthquake occurrence and behavior, as well as seismic hazard assessment.

    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.

  11. Enclosure fire hazard analysis using relative energy release criteria. [burning rate and combustion control

    Coulbert, C. D.

    1978-01-01

    A method for predicting the probable course of fire development in an enclosure is presented. This fire modeling approach uses a graphic plot of five fire development constraints, the relative energy release criteria (RERC), to bound the heat release rates in an enclosure as a function of time. The five RERC are flame spread rate, fuel surface area, ventilation, enclosure volume, and total fuel load. They may be calculated versus time based on the specified or empirical conditions describing the specific enclosure, the fuel type and load, and the ventilation. The calculation of these five criteria, using the common basis of energy release rates versus time, provides a unifying framework for the utilization of available experimental data from all phases of fire development. The plot of these criteria reveals the probable fire development envelope and indicates which fire constraint will be controlling during a criteria time period. Examples of RERC application to fire characterization and control and to hazard analysis are presented along with recommendations for the further development of the concept.

    Experimental nuclear astrophysics aims at determining the reaction rates for astrophysically relevant reactions at their Gamow energies. For charged-particle induced reactions, the access to these energies is usually hindered, in direct measurements, by the presence of the Coulomb barrier between the interacting particles or by electron screening effects, which make hard the determination of the bare-nucleus S(E)-factor of interest for astrophysical codes. The use of the Trojan Horse Method (THM) appears as one of the most suitable tools for investigating nuclear processes of interest for astrophysics. Here, in view of the recent TH measurements, the main destruction channels for deuterium ({sup 2}H), for the two lithium {sup 6,7}Li isotopes, for the {sup 9}Be and the one for the two boron {sup 10,11}B isotopes will be discussed.

    The objective of this study is to determine the catheter-related bloodstream infection (CRBSI) rate in a severely burned patient population, many of whom required prolonged use of central venous catheters (CVCs). Between January 2008 and June 2012, 151 patients underwent placement of 455 five-lumen minocycline/rifampin-impregnated CVCs. CRBSI was defined as at least one blood culture (>100,000 colonies) and one simultaneous roll-plate CVC tip culture (>15 colony forming units) positive for the same organism. Most patients had accidental burns (81.5%) with a mean TBSA of 50%. A mean of three catheters were inserted per patient (range, 1-25). CVCs were inserted in the femoral vein (91.2%), subclavian vein (5.3%), and internal jugular vein (3.3%). Mean overall catheter indwell time was 8 days (range, 0-39 days). The overall rate of CRBSI per 1000 catheter days was 11.2; patients with a TBSA >60% experienced significantly higher rates of CRBSI than patients with a TBSA ≤60% (16.2 vs 7.3, P = .01). CVCs placed through burned skin were four times more likely to be associated with CRBSI than CVCs placed through intact skin. The most common infectious organism was Acinetobacter baumannii. Deep venous thrombosis developed in eleven patients (7%). The overall rate of CRBSI was 11.2, consistent with published rates of CRBSI in burn patients. Thus, femoral placement of 5-lumen CVCs did not result in increased CRBSI rates. These data support the safety of femoral CVC placement in burn patients, contrary to the Centers for Disease Control recommendation to avoid femoral CVC insertion.

    Full Text Available In this paper, we designed and analyzed advanced sodium-cooled fast reactor cores using uranium-free metallic fuels for maximizing burning rate of transuranics (TRU nuclides from PWR spent fuels. It is well known that the removal of fertile nuclides such as 238U from fuels in liquid metal cooled fast reactor leads to the degradation of important safety parameters such as the Doppler coefficient, coolant void worth, and delayed neutron fraction. To resolve the degradation of the Doppler coefficient, we considered adding resonant nuclides to the uranium-free metallic fuels. The analysis results showed that the cores using uranium-free fuels loaded with tungsten instead of uranium have a significantly lower burnup reactivity swing and more negative Doppler coefficients than the core using uranium-free fuels without resonant nuclides. In addition, we considered the use of axially central B4C absorber region and moderator rods to further improve safety parameters such as sodium void worth, burnup reactivity swing, and the Doppler coefficient. The results of the analysis showed that the final design core can consume ~353 kg per cycle and satisfies self-controllability under unprotected accidents. The fuel cycle analysis showed that the PWR–SFR coupling fuel cycle option drastically reduces the amount of waste going to repository and the SFR burner can consume the amount of TRUs discharged from 3.72 PWRs generating the same electricity.

    Mortality rates are important outcome parameters after burn, and can serve as objective end points for quality control. Causes of death after severe burn have changed over time. In a prospective study, eight hundred and eighty-four burn patients were admitted to the Burns and Plastic surgery Hospital in Sulaimani-Kurdistan region of Iraq in 2009. Age, gender, nationality, cause of burn, extent of injury, cause of death and mortality rate were tabulated and analyzed, 338 (38.2%) were male and 546 (61.8%) were female. The highest number of cases occurred in January, with the highest short period incidence occurring in April. Out of 884 cases, 260 persons died. Burn injuries were more frequent and larger with higher mortality in females than in males. Flame was the major cause of burns. Self-inflicted burns were noted mainly in young women. A large number of burns which affect children and females, occur in the domestic setting and could have been prevented. Therefore, it is necessary to implement programs for health education relating to prevention of burn injuries focusing on the domestic setting. Copyright © 2012 Elsevier Ltd and ISBI.

    Background Suicides by carbon monoxide poisoning resulting from burning barbecue charcoal reached epidemic levels in Hong Kong and Taiwan within 5 y of the first reported cases in the early 2000s. The objectives of this analysis were to investigate (i) time trends and regional patterns of charcoal-burning suicide throughout East/Southeast Asia during the time period 1995–2011 and (ii) whether any rises in use of this method were associated with increases in overall suicide rates. Sex- and age-specific trends over time were also examined to identify the demographic groups showing the greatest increases in charcoal-burning suicide rates across different countries. Methods and Findings We used data on suicides by gases other than domestic gas for Hong Kong, Japan, the Republic of Korea, Taiwan, and Singapore in the years 1995/1996–2011. Similar data for Malaysia, the Philippines, and Thailand were also extracted but were incomplete. Graphical and joinpoint regression analyses were used to examine time trends in suicide, and negative binomial regression analysis to study sex- and age-specific patterns. In 1995/1996, charcoal-burning suicides accounted for suicides in all study countries, except in Japan (5%), but they increased to account for 13%, 24%, 10%, 7%, and 5% of all suicides in Hong Kong, Taiwan, Japan, the Republic of Korea, and Singapore, respectively, in 2011. Rises were first seen in Hong Kong after 1998 (95% CI 1997–1999), followed by Singapore in 1999 (95% CI 1998–2001), Taiwan in 2000 (95% CI 1999–2001), Japan in 2002 (95% CI 1999–2003), and the Republic of Korea in 2007 (95% CI 2006–2008). No marked increases were seen in Malaysia, the Philippines, or Thailand. There was some evidence that charcoal-burning suicides were associated with an increase in overall suicide rates in Hong Kong, Taiwan, and Japan (for females), but not in Japan (for males), the Republic of Korea, and Singapore.

    Burn injuries are common and costly; each year, there are more than 200,000 cases, costing the Australian community $150 million. Management of smaller burn injuries in the community can be improved by appropriate first aid, good burn dressings and wound management. This can reduce the risk of the burn becoming deeper or infected, and can potentially reduce the requirement for specialist review or surgery. The objective of this article is to provide healthcare professionals with information about the pathophysiology of burn wound progression. This information includes the aims of burn wound dressings and indications for different types of dressings in different burn depths, advantages of blister debridement, and the reasoning behind advice given to patients after healing of the burn wound. This article provides a framework used by the State Burn Service of Western Australia, by which clinicians can understand the needs of a specific burn wound and apply these principles when choosing an appropriate burn dressing for their patient. Every intervention in the journey of a patient with a burn injury affects their eventual outcome. By managing all burn injuries effectively at every single step, we can reduce burn injury morbidity as a community.

    Accurate pain assessment is essential for proper analgesia during medical procedures in pediatric patients. The Faces, Legs, Activity, Cry, and Consolability (FLACC) scale has previously been shown to be a valid and reliable tool for assessing pediatric procedural pain in research labs. However, no study has investigated how rater factors (gender, number of dressing changes performed/week, burn history, having children, nursing experience, stress at home/work) and patient factors (pain intensity) affect the accuracy of FLACC ratings for procedural pain when implemented by bedside care providers. Twenty-four nurses in an ABA verified Pediatric Burn Center watched four videos of dressing changes for pediatric burn patients in random order three times and rated the children's procedural pain using the FLACC scale. The four videos had standard FLACC scores established by an interdisciplinary panel. Descriptive and mixed modeling analysis was conducted to explore nurse rating accuracy and to evaluate the rater and patient factors that influenced the rating accuracy. The highest accuracy was reached when rating high procedural pain (with a FLACC of 6). Nurses underrated both mild and severe procedural pain. Nurses who had less nursing experience demonstrated significantly higher accuracy than those with more experience. The present study is the first study in the literature to systematically examine the factors influencing the accuracy of FLACC rating for pediatric procedural pain among bedside care providers. The findings suggest that nurse clinical experience and patient pain intensity are two significant contributors to rating accuracy. Copyright © 2016 Elsevier Ltd and ISBI. All rights reserved.

    2014-12-01

    Full Text Available A propagation model of cigarette static burn at the cigarette periphery is proposed. Propagation of cigarette static burn is characterized by intermittent burn of the cigarette paper. The burning rate depends on the period of flash burn of the paper and is independent of the burning width. By measuring the local temperature near the front line of the burning propagation, the rate-determining step was identified as the time required to ignite the paper. A mathematical analysis was performed by calculating the heat transfer at the periphery during the paper heating period, and it was revealed that the thermal properties of the cigarette are the dominant factors of cigarette static burn. Modeling results showed good agreement with measured data.

Material and Methods: This retrospective study was conducted the University of Health Sciences; Şişli Hamidiye Etfal Application and Research Center, Departmant of Plastic, Reconstructive and Aesthetic Surgery and the Intensive Burn Care Unit between April 2009 and April 2014. Burns were assessed based on etiology, anatomical location, percentage of total body surface area affected, and depth of injury. Treatment was categorized as conservative, elective operative, or urgent operative. Results: In the study period, 788 patients were admitted to our Burn Unit. Of these, 240 were females (30.5% and 548 were males (69.5%. The most common type of burn injury in this study was thermal injury (695 cases; 88.2%, followed by electrical injury (67 cases; 8.5%, and chemical, frictional or unknown injuries (26 cases; 3.3%. Majority (more than 85% of the patients had second-degree burns, and some had third-degree burns. Conclusions: Burns commonly affect the hands, and many functional problems may develop if appropriate basic treatments are neglected. The best treatment for burns is prevention. Appropriate indoor arrangement and simple but effective measures that can be taken at home can significantly reduce burn trauma exposure.

    Full Text Available The experimental B(GT strengths of the 59Fe excited states were employed to determine the transition strengths which greatly contribute 59Fe stellar β–decay at typical carbon shell burning temperature. The result has been compared with the theoretical rates FFN (Fuller-Fowler-Newman and LMP (Langanke&Martinez-Pinedo. Impact of the newly determined rate on the synthesis of cosmic γ emitter 60Fe has also been studied using one-zone model calculation. Our results show 59Fe stellar β−decay rate plays an important role in the 60Fe nucleosynthesis. However the uncertainty of the decay rate is rather large due to the error of B(GT strength that requires further studies.

    Burn injury involves a large amount of water, electrolytes and proteins loss trough the burn wound. For this reason, to avoid shock, a wide infusion of fluid is necessary in the first hours after trauma. Many reanimation formulas were proposed in the past years, with different composition: saline, colloids, plasma. The authors have studied 40 burned patients admitted in Verona Burn Center within 4 hours after burn, with burns over 30% of the body surface area. Twenty of them were treated with Baxter reanimation formula (ringer lactated saline, RLS) while the others with Monafo hypertonic lactated saline (HLS), modified by Milan Burn Center. The two randomized groups were assessed and compared. In RLS group total fluid volume infused was higher while sodium requirements was lower than in HLS patients, with statistically significative difference (p electrolytes balance with lower fluid load, reducing tissue oedema and complication rate. Mortality rate was higher in HLS, may be for an higher Roy index in this group.

    Full Text Available Calculation and analysis of B/T (Burning and/or Transmutation rate of MA (minor actinides and Pu (Plutonium has been performed in fast B/T reactor. The study was based on the assumption that the spectrum shift of neutron flux to higher side of neutron energy had a potential significance for designing the fast B/T reactor and a remarkable effect for increasing the B/T rate of MA and/or Pu. The spectrum shifts of neutron have been performed by change MOX to metallic fuel. Blending fraction of MA and or Pu in B/T fuel and the volume ratio of fuel to coolant in the reactor core were also considered. Here, the performance of fast B/T reactor was evaluated theoretically based on the calculation results of the neutronics and burn-up analysis. In this study, the B/T rate of MA and/or Pu increased by increasing the blending fraction of MA and or Pu and by changing the F/C ratio. According to the results, the total B/T rate, i.e. [B/T rate]MA + [B/T rate]Pu, could be kept nearly constant under the critical condition, if the sum of the MA and Pu inventory in the core is nearly constant. The effect of loading structure was examined for inner or outer loading of concentric geometry and for homogeneous loading. Homogeneous loading of B/T fuel was the good structure for obtaining the higher B/T rate, rather than inner or outer loading

    2016-05-04

    Laminar burning velocities of fuels for advanced combustion engines (FACE) C gasoline and of several blends of surrogate toluene reference fuels (TRFs) (n-heptane, iso-octane, and toluene mixtures) of the same research octane number are presented. Effects of ethanol addition on laminar flame speed of FACE-C and its surrogate are addressed. Measurements were conducted using a constant volume spherical combustion vessel in the constant pressure, stable flame regime at an initial temperature of 358 K and initial pressures up to 0.6 MPa with the equivalence ratios ranging from 0.8 to 1.6. Comparable values in the laminar burning velocities were measured for the FACE-C gasoline and the proposed surrogate fuel (17.60% n-heptane + 77.40% iso-octane + 5% toluene) over the range of experimental conditions. Sensitivity of flame propagation to total stretch rate effects and thermo-diffusive instability was quantified by determining Markstein length. Two percentages of an oxygenated fuel of ethanol as an additive, namely, 60 vol% and 85 vol% were investigated. The addition of ethanol to FACE-C and its surrogate TRF-1 (17.60% n-heptane + 77.40% iso-octane + 5% toluene) resulted in a relatively similar increase in the laminar burning velocities. The high-pressure measured values of Markstein length for the studied fuels blended with ethanol showed minimal influence of ethanol addition on the flame’s response to stretch rate and thermo-diffusive instability. © 2016 Taylor & Francis.

    2013-02-01

    Full Text Available In October–November 2011 we measured trace gas emission factors from seven prescribed fires in South Carolina (SC, US, using two Fourier transform infrared spectrometer (FTIR systems and whole air sampling (WAS into canisters followed by gas-chromatographic analysis. A total of 97 trace gas species were quantified from both airborne and ground-based sampling platforms, making this one of the most detailed field studies of fire emissions to date. The measurements include the first emission factors for a suite of monoterpenes produced by heating vegetative fuels during field fires. The first quantitative FTIR observations of limonene in smoke are reported along with an expanded suite of monoterpenes measured by WAS including α-pinene, β-pinene, limonene, camphene, 4-carene, and myrcene. The known chemistry of the monoterpenes and their measured abundance of 0.4–27.9% of non-methane organic compounds (NMOCs and ~ 21% of organic aerosol (mass basis suggests that they impacted secondary formation of ozone (O3, aerosols, and small organic trace gases such as methanol and formaldehyde in the sampled plumes in the first few hours after emission. The variability in the initial terpene emissions in the SC fire plumes was high and, in general, the speciation of the initially emitted gas-phase NMOCs was 13–195% different from that observed in a similar study in nominally similar pine forests in North Carolina ~ 20 months earlier. It is likely that differences in stand structure and environmental conditions contributed to the high variability observed within and between these studies. Similar factors may explain much of the variability in initial emissions in the literature. The ΔHCN/ΔCO emission ratio, however, was found to be fairly consistent with previous airborne fire measurements in other coniferous-dominated ecosystems, with the mean for these studies being 0.90 ± 0.06%, further confirming the value of HCN as a biomass burning tracer.

    Effects of the distributions of excitation energy transfer (EET) rates (homogeneous line widths) on the nonphotochemical (resonant) spectral hole burning (SHB) processes in photosynthetic chlorophyll-protein complexes (reaction center [RC] and CP43 antenna of Photosystem II from spinach) are considered. It is demonstrated that inclusion of such a distribution results in somewhat more dispersive hole burning kinetics. More importantly, however, inclusion of the EET rate distributions strongly affects the dependence of the hole width on the fractional hole depth. Different types of line width distributions have been explored, including those resulting from Foerster type EET between weakly interacting pigments as well as Gaussian ones, which may be a reasonable approximation for those resulting, for instance, from so-called extended Foerster models. For Gaussian line width distributions, it is possible to determine the parameters of both line width and tunneling parameter distributions from SHB data without a priori knowledge of any of them. Concerning more realistic asymmetric distributions, we demonstrate, using the simple example of CP43 antenna, that one can use SHB modeling to estimate electrostatic couplings between pigments and support or exclude assignment of certain pigment(s) to a particular state.

    Ocular or thermal burns account for 7.7%-18% of ocular trauma. The majority of victims are young. The burns occur in the setting of accidents at work or in the home, or during a physical attack. Chemical burns by strong acids or bases are responsible for the most serious injuries. Associated with the destruction of limbal stem cells, they present as recurrent epithelial ulcerations, chronic stromal ulcers, deep stromal revascularization, conjunctival overlap, or even corneal perforation. The initial clinical exam is sometimes difficult to perform in the presence of burning symptoms. Nevertheless, it enables the physician to classify the injury, establish a prognosis, and most importantly, guide the therapeutic management. The Roper-Hall modification of the Hughes classification system is the most widely utilized, broken down into stages based on the size of the stromal opacity and the extent of possible limbal ischemia. This classification is now favorably supplemented by those proposed by Dua and Wagoner, which are based on the extent of the limbal stem cell deficiency. The prognosis of the more serious forms of ocular burns has markedly improved over the last decade because of a better understanding of the physiology of the corneal epithelium. Surgical techniques aimed at restoring the destroyed limbal stem cells have altered the prognosis of severe corneal burns. In order to decrease the incidence of burns, prevention, particularly in industry, is essential.

    Full Text Available Several drugs and toxic substances can cause muscular abnormalities and are frequent causes of acquired myopathies. We present a series of 32 patients, predominance of young adult patients, diagnosed with toxic myopathy. The most common substances inducing myopathy were corticosteroids (56.2% followed by the propoxyphene, neuroleptics, zidovudine and drug-induced hypokalemia. The investigation showed normal serum creatine kinase levels in 65.4%, myopathic pattern of the needle electromyography in 40% and the more frequent histological diagnosis of the muscle biopsy was type 2 fiber atrophy (59.3%. Clinical features, etiology, course of the disease, serum levels of muscular enzymes, electromyographic features and, especially, muscle biopsy features are discussed.Diversos medicamentos e substâncias tóxicas podem causar alterações musculares e são causas freqüentes de miopatia adquirida.

    Full Text Available Severe burn trauma causes serious metabolic derangements. Increased metabolic rate which is apart of a pathophysiologic characteristic of burn trauma results in protein-energy malnutrition. This situation causes impaired wound healing, muscle and fat tissue’s breakdown, growth retardation in children and infections. Nutrition support is vital in the treatment strategies of burn victims to prevent high mortal and disabling complications in this devastating trauma. Our aim in this study is to review management of nutrition in burn victims. (Journal of the Turkish Society Intensive Care 2012; 10: 74-83

Desse modo, os principais fatores de risco associados ao suicídio desses idosos foram: depressão, transtornos mentais graves, estigma referente ao envelhecimento, alcoolismo, automutilações, impulsividade, relações afetivas fragilizadas e história de vida marcada por eventos trágicos.

  5. Simulations of the Neutral-beam-induced Rotation, Radial Electric Field, and Flow Shearing Rate in Next-step Burning Plasmas

    2002-08-13

    Toroidal rotation of plasmas in present tokamaks is beneficial for increasing the stability to wall-induced MHD and appears to reduce the anomalous transport associated with micro-turbulence. This paper calculates the toroidal rotation expected from neutral-beam injection in the proposed FIRE and ITER-FEAT tokamak reactors. Self-consistent burning plasmas for these tokamaks have been constructed using the TRANSP plasma analysis code. Neutral-beam injection has been proposed for FIRE and ITER-FEAT. The neutral-beam-induced torques are computed, and assumptions for the anomalous transport of toroidal angular momentum are used to calculate the toroidal rotation profiles. The central Mach numbers are about 3-8%. The ratio of the rotation speed to the Alfvin speed is less than 1%. Assuming neoclassical poloidal rotation and force balance, the radial electric field and flow shearing rate are calculated. Peak shearing rates near the outboard edge are in the 10-100 krad/s range.

  6. Burns: dressings

    Science.gov (United States)

    2015-01-01

    Introduction Burns are classified according to depth. This overview concerns the treatments for partial-thickness burns, which can be expected or have the potential to heal spontaneously (superficial partial-thickness and mid-dermal partial-thickness burns). Injuries that involve the deeper part of the dermis and require surgical treatments to achieve healing are not the focus of this overview. Methods and outcomes We conducted a systematic overview and aimed to answer the following clinical question: What are the effects of treatments for partial-thickness burns? We searched: Medline, Embase, The Cochrane Library, and other important databases up to January 2014 (BMJ Clinical Evidence overviews are updated periodically; please check our website for the most up-to-date version of this review). Results At this update, searching of electronic databases retrieved 322 studies. After deduplication and removal of conference abstracts, 193 records were screened for inclusion in the overview. Appraisal of titles and abstracts led to the exclusion of 160 studies and the further review of 33 full publications. Of the 33 full articles evaluated, two systematic reviews and two RCTs were added at this update. We performed a GRADE evaluation for 30 PICO combinations. Conclusions In this systematic overview, we categorised the efficacy for 10 interventions, based on information relating to the effectiveness and safety of alginate dressing, biosynthetic dressing, chlorhexidine-impregnated paraffin gauze dressing, hydrocolloid dressing, hydrogel dressing, paraffin gauze dressing, polyurethane film, silicone-coated nylon dressing, silver-impregnated dressing, and silver sulfadiazine cream.

    The literature surrounding pediatric burns has focused on inpatient management. The goal of this study is to characterize the population of burned children treated as outpatients and assess outcomes validating this method of burn care. A retrospective review of 953 patients treated the burn clinic and burn unit of a tertiary care center. Patient age, burn etiology, burn characteristics, burn mechanism, and referral pattern were recorded. The type of wound care and incidence of outcomes including subsequent hospital admission, infection, scarring, and surgery served as the primary outcome data. Eight hundred and thirty children were treated as outpatients with a mean time of 1.8 days for the evaluation of burn injury in our clinic. Scalds accounted for 53% of the burn mechanism, with burns to the hand/wrist being the most frequent area involved. The mean percentage of TBSA was 1.4% for the outpatient cohort and 8% for the inpatient cohort. Burns in the outpatient cohort healed with a mean time of 13.4 days. In the outpatient cohort, nine (1%) patients had subsequent admissions and three (0.4%) patients had concern for infection. Eight patients from the outpatient cohort were treated with excision and grafting. The vast majority of pediatric burns are small, although they may often involve more critical areas such as the face and hand. Outpatient wound care is an effective treatment strategy which results in low rates of complications and should become the standard of care for children with appropriate burn size and home support.

    Cancio, Leopoldo C; Salinas, Jose; Kramer, George C

    2016-10-01

    Fluid resuscitation of burn patients is commonly initiated using modified Brooke or Parkland formula. The fluid infusion rate is titrated up or down hourly to maintain adequate urine output and other endpoints. Over-resuscitation leads to morbid complications. Adherence to paper-based protocols, flow sheets, and clinical practice guidelines is associated with decreased fluid resuscitation volumes and complications. Computerized tools assist providers. Although completely autonomous closed-loop control of resuscitation has been demonstrated in animal models of burn shock, the major advantages of open-loop and decision-support systems are identifying trends, enhancing situational awareness, and encouraging burn team communication.

    Insects found associated with corpse can be used as one of the indicators in estimating postmortem interval (PMI). The objective of this study was to compare the stages of decomposition and faunal succession between a partially burnt pig (Sus scrofa Linnaeus) and natural pig (as control). The burning simulated a real crime whereby the victim was burnt by murderer. Two young pigs weighed approximately 10 kg were used in this study. Both pigs died from pneumonia and immediately placed in an oil palm plantation near a pig farm in Tanjung Sepat, Selangor, Malaysia. One pig was partially burnt by 1-liter petrol while the other served as control. Both carcasses were visited twice per day for the first week and once thereafter. Adult flies and larvae on the carcasses were collected and later processed in a forensic entomology laboratory. Results showed that there was no significant difference between the rate of decomposition and sequence of faunal succession on both pig carcasses. Both carcasses were completely decomposed to remain stage after nine days. The species of flies visiting the pig carcasses consisted of blow flies (Chrysomya megacephala, Chrysomya rufifacies, Hemipyrellia ligurriens), flesh fly (Sarcophagidae.), muscid fly (Ophyra spinigera), soldier fly (Hermetia illucens), coffin fly (Phoridae) and scavenger fly (Sepsidae). The only difference noted was in the number of adult flies, whereby more flies were seen in the control carcass. Faunal succession on both pig carcasses was in the following sequence: Calliphoridae, Sarcophagidae, Muscidae, Phoridae and lastly Stratiomyidae. However, there was overlap in the appearance of members of these families. Blowflies continued to oviposit on both carcasses. Hence postmortem interval (PMI) can still be estimated from the partially burnt pig carcass.

    Intentional burns injuries are associated with high mortality rates, and for survivors, high levels of physical and psychological morbidity. This study provides a comprehensive assessment of intentional burn admissions to the adult Burns Unit at Bir Hospital, Kathmandu, Nepal, during the period 2002-2013. A secondary data analysis of de-identified data of patients hospitalized at Bir Hospital, Kathmandu, with a burn during the period of 1 January 2002 to 31 August 2013. Socio-demographic, injury and psychosocial factors of patients with intentional and unintentional burns are described and compared. Chi-square tests, Fisher's exact test and Wilcoxon rank sum tests were used to determine statistical significance. There were a total of 1148 burn admissions of which 329 (29%) were for intentional burn, 293 (26%) were self-inflicted and 36 (3%) were due to assault. Mortality rates for intentional burns were approximately three times those for unintentional burns (60 vs. 22%). When compared to unintentional burns, patients with intentional burns were more likely to be female (79 vs. 48%), married (84 vs. 67%), younger (25 vs. 30 years), have more extensive burns (total body surface area, %: 55 vs. 25) and higher mortality (60 vs. 22%). Intentional burns were more likely to occur at home (95 vs. 67%), be caused by fire (96 vs. 77%), and kerosene was the most common accelerant (91 vs. 31%). A primary psychosocial risk factor was identified in the majority of intentional burn cases, with 60% experiencing adjustment problems/interpersonal conflict and 32% with evidence of a pre-existing psychological condition. A record of alcohol/substance abuse related to the patient or other was associated with a greater proportion of intentional burns when compared with unintentional burns (17 vs. 4%). The majority of intentional burn patients were female. Almost all intentional burns occurred in the home and were caused by fire, with kerosene the most common accelerant used. Underlying

  4. Reactive burn models and ignition & growth concept

    Science.gov (United States)

    Menikoff, R.; Shaw, M. S.

    Plastic-bonded explosives are heterogeneous materials. Experimentally, shock initiation is sensitive to small amounts of porosity, due to the formation of hot spots (small localized regions of high temperature). This leads to the Ignition & Growth concept, introduced by LeeTarver in 1980, as the basis for reactive burn models. A homo- genized burn rate needs to account for three meso-scale physical effects: (i) the density of active hot spots or burn centers; (ii) the growth of the burn fronts triggered by the burn centers; (iii) a geometric factor that accounts for the overlap of deflagration wavelets from adjacent burn centers. These effects can be combined and the burn model defined by specifying the reaction progress variable λ = g(s) as a function of a dimensionless reaction length s(t) = rbc/ℓbc, rather than by specifying an explicit burn rate. The length scale ℓbc(Ps) = [Nbc(Ps)]-1/3 is the average distance between burn centers, where Nbc is the number density of burn centers activated by the lead shock. The reaction length rbc(t) = ∫t0 D(P(t'))dt' is the distance the burn front propagates from a single burn center, where D(P) is the deflagration speed as a function of the local pressure and t is the time since the shock arrival. A key implementation issue is how to determine the lead shock strength in conjunction with a shock capturing scheme. We have developed a robust algorithm for this purpose based on the Hugoniot jump condition for the energy. The algorithm utilizes the time dependence of density, pressure and energy within each cell. The method is independent of the numerical dissipation used for shock capturing. It is local and can be used in one or more space dimensions. The burn model has a small number of parameters which can be calibrated to fit velocity gauge data from shock initiation experiments.

    -antibacterial treatment or another antiseptic. Most evidence was assessed as low or very low certainty, often because of imprecision resulting from few participants, low event rates, or both, often in single studies. Antiseptics versus topical antibioticsCompared with the topical antibiotic, SSD, there is low certainty evidence that, on average, there is no clear difference in the hazard of healing (chance of healing over time), between silver-based antiseptics and SSD (HR 1.25, 95% CI 0.94 to 1.67; I(2) = 0%; 3 studies; 259 participants); silver-based antiseptics may, on average, increase the number of healing events over 21 or 28 days' follow-up (RR 1.17 95% CI 1.00 to 1.37; I(2) = 45%; 5 studies; 408 participants) and may, on average, reduce mean time to healing (difference in means -3.33 days; 95% CI -4.96 to -1.70; I(2) = 87%; 10 studies; 979 participants).There is moderate certainty evidence that, on average, burns treated with honey are probably more likely to heal over time compared with topical antibiotics (HR 2.45, 95% CI 1.71 to 3.52; I(2) = 66%; 5 studies; 140 participants).There is low certainty evidence from single trials that sodium hypochlorite may, on average, slightly reduce mean time to healing compared with SSD (difference in means -2.10 days, 95% CI -3.87 to -0.33, 10 participants (20 burns)) as may merbromin compared with zinc sulfadiazine (difference in means -3.48 days, 95% CI -6.85 to -0.11, 50 relevant participants). Other comparisons with low or very low certainty evidence did not find clear differences between groups.Most comparisons did not report data on infection. Based on the available data we cannot be certain if antiseptic treatments increase or reduce the risk of infection compared with topical antibiotics (very low certainty evidence). Antiseptics versus alternative antisepticsThere may be some reduction in mean time to healing for wounds treated with povidone iodine compared with chlorhexidine (MD -2.21 days, 95% CI 0.34 to 4.08).

    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

    INTRODUCTION: Correct estimation of the severity of burns is important to obtain the right treatment of the patient and to avoid over- and undertriage. In this study we aimed to assess how often the guidelines for referral of burn injured patients are met at the national burn centre (NBC), Denmark....... METHODS: We included burn patients referred to the NBC in a three-months period. Patient records were systematically analyzed and compared with the national guidelines for referral of burn injured patients. RESULTS: A total of 97 burn injured patients were transferred for treatment at the NBC and the most...... common reason for referral was partial thickness burn exceeding 3% estimated area of burn (55% of the patients) while facial burns (32%) and inhalational injury (25%) were other common reasons. We found that 29 (30%) of the referrals were considered potentially unnecessary according to the guidelines...

    Most cases of burns occurring in medical institutions are associated with activities involving heat. It is very difficult to detect these burns. To date, there are few reports on burns occurring in medical institutions. The purpose of this paper was to analyze the etiology of burns occurring in medical institutions and to elucidate the factors affecting burn depth. We conducted a retrospective analysis of the medical records of patients who visited our center from April 2008 to February 2013. This study enrolled all patients with burns occurring in the medical institution during or related to treatment. We excluded burn patients whose burns were not related to treatment (for example, we excluded patients with scalding burns that occurred in the hospital cafeteria and pediatric patients with hot water burns from the water purifier). However, patients with burns that occurred in the recovery room after general anesthesia were included. A total of 115 patients were enrolled in this study. The average patient age was 41.5 years, with more women than men (M:F=31:84). There were 29 cases (25.3%) of superficial burns (first-degree and superficial second-degree) and 86 cases (74.7%) of deep burns (deep second-degree and third-degree). Hot packs were the most common cause of burns (27 cases, 23.5%), followed by laser therapy, heating pads, and grounding pads, accounting for 15 cases each. There were 89 cases (77.4%) of contact burns and 26 cases (22.6%) of non-contact burns. The most common site of burns was the lower extremities (41 cases, 35.7%). The burn site and contact burns were both factors affecting burn depth. The rate of deep burns was higher in patients with contact burns than in those with non-contact burns (odds ratio 4.26) and was associated with lower body burns (odds ratio 2.85). In burns occurring in medical institutions, there is a high probability of a deep burn if it is a contact burn or occurs in the lower body. Therefore, safety guidelines are needed

    Normal gravity flame blowoff limits in an axisymmetric pmma rod geometry in upward axial stagnation flow are compared with microgravity Burning and Suppression of Solids II (BASS-II) results recently obtained aboard the International Space Station. This testing utilized the same BASS-II concurrent rod geometry, but with the addition of normal gravity buoyant flow. Cast polymethylmethacrylate (pmma) rods of diameters ranging from 0.635 cm to 3.81 cm were burned at oxygen concentrations ranging from 14 to 18 by volume. The forced flow velocity where blowoff occurred was determined for each rod size and oxygen concentration. These blowoff limits compare favorably with the BASS-II results when the buoyant stretch is included and the flow is corrected by considering the blockage factor of the fuel. From these results, the normal gravity blowoff boundary for this axisymmetric rod geometry is determined to be linear, with oxygen concentration directly proportional to flow speed. We describe a new normal gravity upward flame spread test method which extrapolates the linear blowoff boundary to the zero stretch limit to resolve microgravity flammability limits, something current methods cannot do. This new test method can improve spacecraft fire safety for future exploration missions by providing a tractable way to obtain good estimates of material flammability in low gravity.

    In October-November 2011 we measured the trace gas emission factors from 7 prescribed fires in South Carolina, U.S. using two Fourier transform infrared spectrometer (FTIR) systems and whole air sampling (WAS) into canisters followed by gas-chromatographic analyses. The fires were intended to emulate high-intensity burns as they were lit during the dry season and in most cases represented stands that had not been treated with prescribed burns in 10+ years, if at all. A total of 97 trace gas species are reported here from both airborne and ground-based platforms making this one of the most detailed field studies of fire emissions to date. The measurements included the first data for a suite of monoterpene compounds emitted via distillation of plant tissues during real fires. The known chemistry of the monoterpenes and their measured abundance of ~0.40% of CO (molar basis), ~3.9% of NMOC (molar basis), and ~21% of organic aerosol (mass basis), suggests that they impacted post-emission formation of ozone, aerosol, and small organic trace gases such as methanol and formaldehyde in the sampled plumes. The variability in the terpene emissions in South Carolina (SC) fire plumes was high and, in general, the speciation of the emitted gas-phase non-methane organic compounds was surprisingly different from that observed in a similar study in nominally similar pine forests in North Carolina ~20 months earlier. It is likely that the slightly different ecosystems, time of year and the precursor variability all contributed to the variability in plume chemistry observed in this study and in the literature. The ΔHCN/ΔCO emission ratio, however, is fairly consistent at 0.9 ± 0.06 % for airborne fire measurements in coniferous-dominated ecosystems further confirming the value of HCN as a good biomass burning indicator/tracer. The SC results also support an earlier finding that C3-C4 alkynes may be of use as biomass burning indicators on the time-scale of

    Currently, limited long-term data on hyperglycaemia and insulin sensitivity in burn patients are available and the data that do exist are primarily related to paediatric severe burns. The aim of this study was to assess if burn is associated with increased post-burn admissions for diabetes mellitus. A population-based longitudinal study using linked hospital morbidity and death data from Western Australia was undertaken of all persons hospitalized for a first burn (n=30,997) in 1980-2012 and a frequency matched non-injury comparison cohort, randomly selected from Western Australia's birth registrations and electoral roll (n=123,399). Crude admission rates and summed length of stay for diabetes mellitus were calculated. Negative binomial and Cox proportional hazards regression modelling were used to generate incidence rate ratios (IRR) and hazard ratios (HR), respectively. After adjustment for socio-demographic factors and pre-existing health status, the burn cohort had 2.21 times (95% Confidence Interval (CI): 1.36-1.56) as many admissions and almost three times the number of days in hospital with a diabetes mellitus diagnosis (IRR, 95% CI: 2.94, 2.12-4.09) than the uninjured cohort. Admission rates were significantly elevated for those burned during childhood (diabetes mellitus in the burn cohort provide evidence that burns have longer term effects on blood glucose and insulin regulation after wound healing. The first five years after burn discharge appears to be a critical period with significantly elevated incident admissions for diabetes mellitus during this time. Results would suggest prolonged clinical management after discharge and or wound healing to minimise post-burn admissions for diabetes mellitus is required. Copyright © 2016 Elsevier Ltd and ISBI.

    Thermal injuries greater than 20% body surface area (BSA) result in systemic shock with generalized edema in addition to local tissue destruction. Burn shock is induced by a variety of mediators, mainly immunomodulative cytokines. This experimental study evaluates if burn shock can be induced in healthy rats by transfer of burn plasma (BP) with mediators. Thermal injury was induced by hot water (100 degrees C water, 12 s, 30% BSA) in male syngenic Wistar rats. Donor rats were killed 4 h posttrauma, and BP was harvested. Burn plasma was transferred to healthy animals by continuous intravenous infusion in three types of dilution (100%, 10%, and 1%). Positive controls were directly examined 4 h after thermal injury, and negative control rats had a continuous infusion done with sham burn (SB) plasma (37 degrees C water, 12 s, 30% BSA). Afterwards, intravital fluorescence microscopy was performed in postcapillary mesenteric venules at 0, 60, and 120 min. Edema formation was assessed by relative changes over time in fluorescence intensity of fluorescein isothiocyanate-albumin in the intravascular versus the extravascular space. The interactions of leucocytes and endothelium were evaluated by quantification of leukocyte sticking. Additionally, microhemodynamic (volumetric blood flow, erythrocyte velocity, venular wall shear rate, venular diameters) and macrohemodynamic parameters (blood pressure, heart frequency, temperature) were assessed online (arterial catheter). For statistics, an ANOVA was performed with Bonferroni adjustment procedure. Differences were considered significant when P edema formation remains uncertain and requires further investigation.

    Summary Burn injuries put a huge financial burden on patients and healthcare systems. They are the 8th leading cause of mortality and the 13th most common cause of morbidity in our country. We used data from our Burn Registry Program to evaluate risk factors for mortality and lethal area fifty percent (LA50) in all burn patients admitted over two years. We used multiple logistic regressions to identify risk factors for mortality. LA50 is a reliable aggregate index for hospital care quality and a good measure for comparing results, also with those of other countries. 28,690 burn patients sought medical attention in the Emergency Department, and 1721 of them were admitted. Male to female ratio was 1,75:1. 514 patients were under 15 years old. Median age was 25 (range: 3 months – 93 years). Overall, probability of death was 8.4%. LA50 was 62.31% (CI 95%: 56.57-70.02) for patients aged 15 and over and 72.52% (CI 95%: 61.01-100) for those under 15. In the final model, we found that Adjusted OR was significant for age, female sex, TBSA and inhalation injury (P < 0.05). LA50 values showed that children tolerate more extensive burns. Female sex, burn size, age and inhalation injury were the main risk factors for death. Authorities should pay special attention to these variables, especially in prevention programs, to reduce mortality and improve patient outcome. Children have better outcome than adults given equal burn size. Suicide rates are higher for women than men in our country PMID:27857645

    Hypothermia, acidaemia and coagulopathy in trauma is associated with significant mortality. This study aimed to identify the incidence of the lethal triad in major burns, and describe demographics and outcomes. Patients admitted during a 71 month period with a total body surface area burn (TBSA)≥30% were identified. A structured review of a prospective database was conducted. The lethal triad was defined as a combination of coagulopathy (International normalised ratio>1.2), hypothermia (temperature≤35.5°C) and acidaemia (pH≤7.25). Fifteen of 117 patients fulfilled the criteria for the lethal triad on admission. Lethal triad patients had a higher median (IQR) abbreviated burn severity index (ABSI) (12 (9-13) vs. 8.5 (6-10), p=0.001), mean (SD) TBSA burn (59.2% (18.7) vs. 47.9% (18.1), p=0.027), mean (SD) age (46 (22.6) vs. 33 (28.3) years, p=0.033), and had a higher incidence of inhalational injury (p0.05). The lethal triad was associated with increased mortality (66.7% vs. 13.7%, plethal triad was not shown to be a predictor of mortality (p>0.05). Burn patients with the lethal triad have a high mortality rate which reflects the severity of the injury sustained. Copyright © 2014 Elsevier Ltd and ISBI. All rights reserved.

    Pediatric electrical and chemical burns are rare injuries, and the care of these patients varies significantly. We reviewed our experience in management of electrical and chemical burns to analyze the clinical course, management, and outcomes. A retrospective review was conducted on children with chemical and electrical burns presenting to two large regional pediatric burn centers over a 10-y period (2002-2012). Clinical data including patient demographics, nature of burns, management, and outcomes were collected and analyzed. There were 50 cases, 25 chemical and electrical burns each. Overall, the mean±standard deviation age was 6.2±5.6 y, and the mean total body surface area burn was 4.3±3.2%. Chemical burns were larger, had less depth, and shorter length of stay, whereas electrical burns were smaller, deeper, and had a longer length of stay. Two chemical burns and six electrical burns required grafting. Twelve percent of electrical burns required rehabilitation, and 20% required compression garments for hypertrophic scars. Six percent required late surgeries. Pediatric electric and chemical burns are rare and require specialized care. Graft rates are not high but are mostly noted in electrical burns.

    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.

    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.

    A significant number of burns and deaths from fire are intentionally wrought. Rates of intentional burns are unevenly distributed throughout the world; India has a particularly high rate in young women whereas in Europe rates are higher in men in mid-life. Data from hospitalized burn patients worldwide reveal incidence rates for assault by fire and scalds ranging from 3% to 10%. The average proportion of the body surface area burned in an assault by fire or scalds is approximately 20%. In different parts of the world, attempted burning of others or oneself can be attributed to different motives. Circumstances under which assaults occur fall largely into the categories of interpersonal conflict, including spousal abuse, elder abuse, or interactions over contentious business transactions. Contributing social factors to assaults by burning include drug and alcohol abuse, non-constructive use of leisure time, non-participation in religious and community activities, unstable relationships, and extramarital affairs. Although the incidence of self-mutilation and suicide attempts by burning are relatively low, deliberate self-harm carries a significant risk of death, with an overall mortality rate of 65% worldwide. In those who resort to self-immolation, circumstantial themes reflect domestic discord, family dysfunction, and the social ramifications of unemployment. Preventing injurious burn-related violence requires a multifaceted approach, including legislation and enforcement, education, and advocacy. Better standardized assessment tools are needed to screen for risks of abuse and for psychiatric disorders in perpetrators. Copyright © 2012 Elsevier Ltd and ISBI. All rights reserved.

  9. Tumores do tronco cerebral: estudo anatomopatológico em 35 casos de necrópsia

    Full Text Available Os tumores do tronco cerebral são raros e geralmente tratados sem diagnóstico histopatológico. Sua incidência varia na literatura entre 1,09% e 17,5% dos tumores cerebrais. O objetivo do trabalho foi relatar a casuísti desses tumores em 28500 necrópsias realizadas de 1952 a 1985 no Departamento de Anatomia Patológica da Santa Casa de São Paulo. Enfatizamos os aspectos neuropatológicos, comparamos nossos casos com os de outras séries e salientamos os tumores mais observados nessa região, com a finalidade de procurar contribuir para melhor abordagem terapêutica. Utilizamos alguns dados clínicos e, através do exame anatomopatológico, localizamos o tumor no tronco cerebral sendo o diagnóstico microscópico estabelecido segundo os critérios da Organização Mundial da Saúde. Dos 428 tumores intracranianos observados, 35 estavam localizados no tronco cerebral. Foram aqui incluídos os tumores próprios do tronco cerebral e as metástases e excluídos os tumores que infiltravam o tronco. A maior incidência ocorreu na primeira década e a causa de óbito predominante foi edema cerebral. A localização preferencial foi a ponte e o tumor mais freqüente foi o glioblas-tomia multiforme (19 casos. As metástases ficaram em segundo lugar na freqüência (9 casos, na maioria dos casos de origem pulmonar. Apesar de alguns autores se posicionarem contra a biópsia de tumor nessa região, baseando-se no alto risco cirúrgico, discordamos dessa opinião, pois acreditamos que, frente ao diagnóstico de glioma, será importante a caracterização ou não de malignidade. Ainda, não devemos deixar de considerar os diagnósticos diferenciais de processo expansivo no tronco. Enfim, com o diagnóstico anatomopatológico de glioma ou de uma das possibilidades aventadas, o procedimento terapêutico poderá ser mais adequado.

    Full Text Available Pompe disease (PD can be diagnosed by measuring alpha-glucosidase levels or by identifying mutations in the gene enzyme. Muscle biopsies can aid diagnosis in doubtful cases. Methods: A review of muscle biopsy from 19 cases of PD (infantile, 6 cases; childhood, 4 cases; and juvenile/adult, 9 cases. Results: Vacuoles with or without glycogen storage were found in 18 cases. All cases had increased acid phosphatase activity. The vacuole frequency varied (almost all fibers in the infantile form to only a few in the juvenile/adult form. Atrophy of type 1 and 2 fibers was frequent in all forms. Atrophic angular fibers in the NADH-tetrazolium reductase and nonspecific esterase activity were observed in 4/9 of the juvenile/adult cases. Conclusion: Increased acid phosphatase activity and vacuoles were the primary findings. Most vacuoles were filled with glycogen, and the adult form of the disease had fewer fibers with vacuoles than the infantile or childhood forms.O diagnóstico da doença de Pompe (PD pode ser feito pela dosagem da enzima alfa-glicosidase ou pela mutação do seu gene codificador.

    Full Text Available INTRODUÇÃO: Tem ocorrido aumento da população de idosos e estes vêm envelhecendo em melhores condições clínicas do que no passado. Entretanto, a distribuição e evolução das doenças renais nos idosos ainda são pouco conhecidas, em parte devido à resistência em indicar biópsia renal. OBJETIVO: Avaliar a distribuição, a evolução e as características clínicas das nefropatias diagnosticadas por biópsia em pacientes idosos. PACIENTES E MÉTODOS: Foram avaliadas todas as biópsias renais percutâneas de rins nativos. Elas foram realizadas entre janeiro de 1990 e dezembro de 2006 em 71 pacientes com idade mínima de 60 anos (67,3 ± 6,5 anos, sendo 47 do gênero masculino e 24 do feminino. Os pacientes foram agrupados conforme a indicação clínica da biópsia. RESULTADOS: Síndrome nefrótica foi verificada em 35 pacientes (49,3% associada, na maioria dos casos, à nefropatia membranosa (17 casos, seguida por amiloidose e glomeruloesclerose segmentar e focal com 7 casos cada. Hipótese diagnóstica de injúria renal aguda (IRA, com 19 pacientes, teve como principais diagnósticos a necrose tubular aguda (6 casos e a nefropatia do cilindro (3 casos. Dentre os 19 casos, apenas dois tiveram evolução satisfatória, enquanto os demais morreram precocemente ou evoluíram para doença renal avançada.

    The aim of this study was to describe the epidemiology of burns admitted to the National Burns Unit (NBU) in the Sultanate of Oman between 1987 and 2011. This is a retrospective review of burn patients admitted to Oman's National Burns Unit (NBU) between 1987 and 2011. The data extracted from the national burn registry. The study describes the admission rate by gender and age groups, occupation, causes of burns, time-to-admission, length of stay and in-hospital mortality of burns between 1987 and 2011. During a 25-year from 1987 to 2011, there were 3531 burn patients admitted to the National Burns Unit in Oman. The average admission rate to NBU is 7.02 per 100,000 persons per year. On average, males were more likely to be admitted to the NBU than females during the study period (P value burns. About half of all patients admitted to the NBU have burns to more than 11% of total body surface area (TBSA). The average stay in hospital was estimated to be 15.3 days per patient. The average in-hospital mortality rate was estimated to be 8.2% per year (range 1.9-22%). Burns are significant public health issue in the Sultanate of Oman. Children are disproportionately over-represented in this study. Prevention programmes are urgently needed to address this "silent and costly epidemic." Copyright © 2013 Elsevier Ltd and ISBI.

    Prophylactic antibiotic use in childhood burns is controversial. The efficiency of antibiotic prophylaxis in 77 pediatric burn patients was evaluated. Forty-seven patients received prophylactic antibiotics (Group AP), while 30 patients received no prophylaxis (Group NP). Age, wound depth, day of admission, mechanism of burn injury, type of dressings were similar for both groups (p > 0.05). Wound infection rates were 21.3 % in Group AP and 16.7 % in Group NP (p > 0.05). S. aureus, Enterobacter spp., P. aeruginosa, and E. coli were the most common microorganisms. Patients with wound colonization and infection had a larger burned total body surface area (BTBSA) in both groups (p beneficial and cost-effective results in the treatment of childhood burns is recommended.

    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.

  18. Mitigating Satellite-Based Fire Sampling Limitations in Deriving Biomass Burning Emission Rates: Application to WRF-Chem Model Over the Northern sub-Saharan African Region

    Largely used in several independent estimates of fire emissions, fire products based on MODIS sensors aboard the Terra and Aqua polar-orbiting satellites have a number of inherent limitations, including (a) inability to detect fires below clouds, (b) significant decrease of detection sensitivity at the edge of scan where pixel sizes are much larger than at nadir, and (c) gaps between adjacent swaths in tropical regions. To remedy these limitations, an empirical method is developed here and applied to correct fire emission estimates based on MODIS pixel level fire radiative power measurements and emission coefficients from the Fire Energetics and Emissions Research (FEER) biomass burning emission inventory. The analysis was performed for January 2010 over the northern sub-Saharan African region. Simulations from WRF-Chem model using original and adjusted emissions are compared with the aerosol optical depth (AOD) products from MODIS and AERONET as well as aerosol vertical profile from CALIOP data. The comparison confirmed an 30-50% improvement in the model simulation performance (in terms of correlation, bias, and spatial pattern of AOD with respect to observations) by the adjusted emissions that not only increases the original emission amount by a factor of two but also results in the spatially continuous estimates of instantaneous fire emissions at daily time scales. Such improvement cannot be achieved by simply scaling the original emission across the study domain. Even with this improvement, a factor of two underestimations still exists in the modeled AOD, which is within the current global fire emissions uncertainty envelope.

    The accuracy rates of the clinical assessment techniques used in grading burn injuries remain significantly low for partial thickness burns. In this paper, we present experimental results from terahertz characterization of 2nd and 3rd degree burn wounds induced on a rat model. Reflection measurements were obtained from the surface of both burned and normal skin using pulsed terahertz spectroscopy. Signal processing techniques are described for interpretation of the acquired terahertz waveform and differentiation of burn wounds. Furthermore, the progression of burn injuries is shown by comparison between acute characterization and 72-hours survival studies. While the water content of healthy and desiccated skin has been considered as a source of terahertz signal contrast, it is demonstrated that other biological effects such as formation of post-burn interstitial edema as well as the density of the discrete scattering structures in the skin (such as hair follicles, sweat glands, etc.) play a significant role in the terahertz response of the burn wounds.

    Though multiple studies have demonstrated superior outcomes amongst adult burn patients at verified burn centers (VBCs) relative to nondedicated burn centers (NBCs), roughly half of such patients meeting American Burn Association (ABA) referral guidelines are not sent to these centers. We sought examine referral patterns amongst pediatric burn patients. Retrospective review of a statewide patient database identified pediatric burn patients from 2000 to 2007 using International Classification of Disease (ICD-9) discharge codes. These injuries were crossreferenced with ABA referral criteria to determine compliance with the ABA guidelines. 1831 children sustained burns requiring hospitalization during the study period, of which 1274 (70%) met ABA referral criteria. Of 557 treated at NBCs, 306 (55%) met criteria for transfer. Neither age, gender, nor payer status demonstrated significant association with treatment center. VBCs treated more severely injured patients, but there was no difference in survival or rate of discharge home from NBCs versus VBCs. Studies to evaluate differences in functional outcomes between pediatric burn patients treated at VBCs versus NBCs would be beneficial to ensure optimization of outcomes in this population.

  1. Nutritional Therapy in Burns

    Full Text Available A burn is characterized by the damage to one’s body tissues caused by heat, chemicals, electricity, or radiation. The incidence of burn injuries has recently been decreasing. However, it is a fact that burns constitute a significant problem all over the world, with a few million people being affected by burns each year. A burn is an extensive trauma that affects the whole organism and determines the prognosis through its physiopathology. The case of the burn patient is also characterized by the acute phase response. Since burn patients have a non-functional skin barrier, they experience loss of liquids, minerals, proteins and electrolytes. They can also develop protein, energy and micro-nutrition deficiencies due to intense catabolic processes, infections and increased bodily needs in case of wound healing. Therefore, nutritional therapy is one of the major steps that need to be monitored from the initial moments of the burn injury through to the end of the burn treatment. This study focuses on the significance of nutritional therapy for burn patients in the light of current literature.

    The painful events associated with the treatment of a severe burn can, because of their long-lasting and repetitive characteristics, be one of the most excruciating experiences in clinical practice. Moreover, burn pain has been shown to be detrimental to burn patients. Although nociception and peripheral hyperalgesia are considered the major causes of burn pain, the study of more hypothetical mechanisms like central hyperalgesia and neuropathic pain may lead to a better understanding of burn pain symptoms and to new therapeutic approaches. Continuous pain and intermittent pain due to therapeutic procedures are two distinct components of burn pain. They have to be evaluated and managed separately. Although continuous pain is by far less severe than intermittent pain, the treatment is, in both cases, essentially pharmacological relying basically on opioids. Because of wide intra- and inter-individual variations, protocols will have to leave large possibilities of adaptation for each case, systematic pain evaluation being mandatory to achieve the best risk/benefit ratio. Surprisingly, the dose of medication decreases only slowly with time, a burn often remaining painful for long periods after healing. Non pharmacological treatments are often useful and sometimes indispensable adjuncts; but their rationale and their feasibility depends entirely on previous optimal pharmacological control of burn pain. Several recent studies show that burn pain management is inadequate in most burn centres.

    Following a major burn, skeletal muscle protein synthesis rate increases but is often insufficient to compensate for massively elevated muscle protein breakdown rates. Given the long-term nature of the pathophysiologic response to burn injury, we hypothesized that muscle protein synthesis rate would be chronically elevated in severely burned children. The objectives of this study were to characterize muscle protein synthesis rate of burned children over a period of 24 months after injury and to identify predictors that influence this response. A total of 87 children with 40% or greater total body surface area (TBSA) burned were included. Patients participated in stable isotope infusion studies at 1, 2, and approximately 4 weeks after burn and at 6, 12, and 24 months after injury to determine skeletal muscle protein fractional synthesis rate. Generalized estimating equations with log link normal distribution were applied to account for clustering of patients and control for patient characteristics. Patients (8 ± 6 years) had large (62, 51-72% TBSA) and deep (47% ± 21% TBSA third degree) burns. Muscle protein fractional synthesis rate was elevated throughout the first 12 months after burn compared with established values from healthy young adults. Muscle protein fractional synthesis rate was lower in boys, in children older than 3 years, and when burns were greater than 80% TBSA. Muscle protein synthesis is elevated for at least 1 year after injury, suggesting that greater muscle protein turnover is a component of the long-term pathophysiologic response to burn trauma. Muscle protein synthesis is highly affected by sex, age, and burn size in severely burned children. These findings may explain the divergence in net protein balance and lean body mass in different populations of burn patients. Prognostic study, level III.

    The use of explosives and suicide bombings has become more frequent since October 2000. This change in the nature of terror attacks has marked a new era in the Israeli-Palestinian conflict. We previously reported that the incidence of thermal injuries has since risen. However, the rise in the incidence of burns among victims of terror was proportionate to the rise in the incidence of burns among all trauma victims. This paper presents data from the Israeli National Trauma Registry during the years 1997--2003, to compare the severity of injuries and outcome (mortality rates) in terror victims with and without burn injuries. We also compare the severity of injuries and outcome (mortality rates) for patients with terror-attack related burns to non terror-attack related burns during the same period. Data was obtained from the Israeli National Trauma Registry for all patients admitted to 8 to 10 hospitals in Israel between 1997 and 2003. We analyzed and compared demographic and clinical characteristics of 219 terror-related burn patients (terror/burn), 2228 terror patients with no associated burns (Terror/no-burn) and 6546 non terror related burn patients (burn/no-terror). Severity of injuries was measured using the injury severity score, and burn severity by total body surface percentage indices. Admission rates to Intensive Care Units (ICU) and total length of hospitalization were also used to measure severity of injuries. In-hospital mortality rates were used to indicate outcome. Of burn/terror patients, 87.2% suffered other accompanying injuries, compared with 10.4% of burn/no-terror patients. Of burn/terror patients, 49.8% were admitted to ICU compared with only 11.9% of burn/no-terror patients and 23.8% of no-burn/terror patients. Mean length of hospital stay was 18.5 days for the terror/burn group compared with 11.1 days for the burn/no-terror group and 9.5 days for the terror/no-burn group. Burn/terror patients had a significantly higher injury severity score

    Full Text Available Microcellular combustible objects for application of combustible case, caseless ammunition or combustible detonator-holding tubes are fabricated through one-step foaming process, in which supercritical CO2 is used as foaming agent. The formulations consist of inert polymer binder and ultra fine RDX. For the inner porous structures of microcellular combustible objects, the cell sizes present a unimodal or bimodal distribution by adjusting the foaming conditions. Closed bomb test is to investigate the influence of both porous structure style and RDX content on burning behavior. The sample with bimodal distribution of cell sizes burns faster than that with unimodal distribution, and the concentration of RDX can influence the burning characteristics in a positive manner. In addition, the translation of laminar burning to convective burning is determined by burning rate versus pressure curves of samples at two different loading densities, and the resulting transition pressure is 30 MPa. Moreover, the samples with bigger sample size present higher burning rate, resulting in providing deeper convective depth. Dynamic vivacity of samples is also studied. The results show that the vivacity increases with RDX content and varies with inner structure.

    This is a report of the first descriptive analytic study of a group of 183 burn patients, treated in the Burn Unit at the University Hospital of Cartagena, Colombia during the period since January 1985 until December 1990. There is presented experience with the selected group of 24 patients in whom the diagnosis of burn was associated with epilepsy. There is also analysed and described the gravity of the scars sequels, neurological disorders, the complication of the burn and an impact of this problem on the patient, his (her) family and the community. It is very important to report that there was found Neurocisticercosis in 66.6% of the group of burn patients with epilepsy, and it is probably the first risk factor of burn in this group.

    We present the use of one-proton-removal reactions of loosely bound nuclei at intermediate energies as an indirect method in nuclear astrophysics, with particular reference to the results of a GANIL experiment with a cocktail beam around ^23Al at 50 MeV/nucleon. Momentum distributions of the core fragments, inclusive and in coincidence with gamma rays, from which we determine configuration mixing in the structure of the ground states of the projectile nuclei, were measured. The method has the advantage that it can be used for beams of low quality, such as cocktail beams, and intensities as low as a few pps. These breakup reactions provide information on H-burning reaction rates for ^22Mg(p,γ)^23Al and ^23Al(p,γ)^24Si, important in novae and X-ray bursts.

    Despite major advances in the area of burn management, burn injury continues to be a leading cause of pediatric mortality and morbidity. Facial burns in particular are devastating to the affected child and result in numerous physical and psychosocial sequelae. Although many of the principles of adult burn management can be applied to a pediatric patient with facial burns, the surgeon must be cognizant of several important differences. Facial burns and subsequent scar formation can drastically affect the growth potential of a child's face. Structures such as the nose and teeth may become deformed due to abnormal external forces caused by contractures. Serious complications such as occlusion amblyopia and microstomia must be anticipated and urgently addressed to avert permanent consequences, whereas other reconstructive procedures can be delayed until scar maturation occurs. Furthermore, because young children are actively developing the concept of self, severe facial burns can alter a child's sense of identity and place the child at high risk for future emotional and psychologic disturbances. Surgical reconstruction of burn wounds should proceed only after thorough planning and may involve a variety of skin graft, flap, and tissue expansion techniques. The most favorable outcome is achieved when facial resurfacing is performed with respect to the aesthetic units of the face. Children with facial burns remain a considerable challenge to their caregivers, and these patients require long-term care by a multidisciplinary team of physicians and therapists to optimize functional, cosmetic, and psychosocial outcomes.

  14. Reactive burn models and ignition & growth concept

    Directory of Open Access Journals (Sweden)

    Shaw M.S.

    2011-01-01

    Full Text Available Plastic-bonded explosives are heterogeneous materials. Experimentally, shock initiation is sensitive to small amounts of porosity, due to the formation of hot spots (small localized regions of high temperature. This leads to the Ignition & Growth concept, introduced by LeeTarver in 1980, as the basis for reactive burn models. A homo- genized burn rate needs to account for three meso-scale physical effects: (i the density of active hot spots or burn centers; (ii the growth of the burn fronts triggered by the burn centers; (iii a geometric factor that accounts for the overlap of deflagration wavelets from adjacent burn centers. These effects can be combined and the burn model defined by specifying the reaction progress variable λ = g(s as a function of a dimensionless reaction length s(t = rbc/ℓbc, rather than by specifying an explicit burn rate. The length scale ℓbc(Ps = [Nbc(Ps]−1/3 is the average distance between burn centers, where Nbc is the number density of burn centers activated by the lead shock. The reaction length rbc(t = ∫t0 D(P(t′dt′ is the distance the burn front propagates from a single burn center, where D(P is the deflagration speed as a function of the local pressure and t is the time since the shock arrival. A key implementation issue is how to determine the lead shock strength in conjunction with a shock capturing scheme. We have developed a robust algorithm for this purpose based on the Hugoniot jump condition for the energy. The algorithm utilizes the time dependence of density, pressure and energy within each cell. The method is independent of the numerical dissipation used for shock capturing. It is local and can be used in one or more space dimensions. The burn model has a small number of parameters which can be calibrated to fit velocity gauge data from shock initiation experiments.

    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

Along with improved survival, new challenges have emerged in the management of burn patients. Infections top the list of the most common complication after burns, and sepsis is the leading cause of death in both adult and pediatric burn patients. The diagnosis and management of sepsis in burns is complex as a tremendous hypermetabolic response secondary to burn injury can be superimposed on systemic infection, leading to organ dysfunction. The management of a septic burn patient represents a challenging scenario that is commonly encountered by providers caring for burn patients despite preventive efforts. Here, we discuss the current perspectives in the diagnosis and treatment of sepsis and septic shock in burn patients.

  18. Burns and military clothing.

    2001-02-01

    Burn injury is a ubiquitous threat in the military environment. The risks during combat are well recognised, but the handling of fuel, oil, munitions and other hot or flammable materials during peacetime deployment and training also imposes an inherent risk of accidental burn injury. Over the last hundred years, the burn threat in combat has ranged from nuclear weapons to small shoulder-launched missiles. Materials such as napalm and white phosphorus plainly present a risk of burn, but the threat extends to encompass personnel in vehicles attacked by anti-armour weapons, large missiles, fuel-air explosives and detonations/conflagrations on weapons platforms such as ships. Large numbers of burn casualties were caused at Pearl Harbor, in Hiroshima and Nagasaki, Vietnam, during the Arab/Israeli Wars and in the Falkland Islands conflict. The threat from burns is unlikely to diminish, indeed new developments in weapons seek to exploit the vulnerability of the serviceman and servicewoman to burns. Clothing can be a barrier to some types of burn--both inherently in the properties of the material, but also by trapping air between clothing layers. Conversely, ignition of the clothing may exacerbate a burn. There is hearsay that burnt clothing products within a wound may complicate the clinical management, or that materials that melt (thermoplastic materials) should not be worn if there is a burn threat. This paper explores the incidence of burn injury, the mechanisms of heat transfer to bare skin and skin covered by materials, and the published evidence for the complication of wound management by materials. Even light-weight combat clothing can offer significant protection to skin from short duration flash burns; the most vulnerable areas are the parts of the body not covered--face and hands. Multilayered combat clothing can offer significant protection for short periods from engulfment by flames; lightweight tropical wear with few layers offers little protection. Under

    This study aims to document the epidemiologic pattern and outcome of burn injuries in the country's first national burn centre. This case series study was conducted over a 2-year period at Burns Care Centre (BCC), Pakistan Institute of Medical Sciences (PIMS), Islamabad. The study included all burn injury patients who primarily presented to and were managed at the centre. Those patients who presented more than 24 h after injury or those who were initially managed at some other hospital were excluded from the study. Initial assessment and diagnosis was made by thorough history, physical examination and necessary investigations. Patients with major burns, high voltage electric burns and those needing any surgical interventions were admitted for indoor management. Patients with minor burns were discharged home after necessary emergency management, home medication and follow-up advice. The sociodemographic profile of the patients, site of sustaining burn injury, type and extent (total body surface area (TBSA), skin thickness involved and associated inhalational injury) of burn and outcome in terms of survival or mortality, etc., were all recorded on a proforma. The data were subjected to statistical analysis. Out of a total of 13,295 patients, there were 7503 (56.43%) males and 5792 (43.56%) females. The mean age for adults was 33.63±10.76 years and for children it was 6.71±3.47 years. The household environment constituted the commonest site of burns (68%). Among all age groups and both genders, scalds were the commonest burns (42.48%), followed by flame burns (39%) and electrical burns (9.96%). The affected mean TBSA was 10.64±11.45% overall, while for the hospitalised subset of patients the mean TBSA was 38.04±15.18%. Most of the burns were partial thickness (67%). Inhalation injury was found among 149 (1.12%) patients. Most of the burns were non-intentional and only 96 (0.72%) were intentional. A total of 1405 patients (10.58%) were admitted while the remainder

    The aim of this study was to characterize the epidemiology of severe burns in the Netherlands, including trends in burn centre admissions, non burn centre admissions and differences by age. Patients with burn-related primary admission in a Dutch centre from 1995 to 2011 were included. Nationwide prospectively collected data were used from three separate historical databases and the uniform Dutch Burn Repository R3 (2009 onwards). General hospital data were derived from the National Hospital Discharge Register. Age and gender-adjusted rates were calculated by direct standardization, using the 2005 population as the reference standard. The annual number of admitted patients increased from 430 in 1995 to 747 in 2011, incidence rates increased from 2.72 to 4.66 per 100,000. Incidence rates were high in young children, aged 0-4 years and doubled from 10.26 to 22.96 per 100,000. Incidence rates in persons from 5 up to 59 increased as well, in older adults (60 years and older) admission rates were stable. Overall burn centre mortality rate was 4.1%, and significantly decreased over time. There was a trend towards admissions of less extensive burns, median total burned surface area (TBSA) decreased from 8% to 4%. Length of stay and length of stay per percent TBSA decreased over time as well. Data on 9031 patients admitted in a 17-year period showed an increasing incidence rate of burn-related burn centre admissions, with a decreasing TBSA and decreasing in-burn centre mortality. These data are important for prevention and establishment of required burn care capacity. Copyright © 2014 Elsevier Ltd and ISBI. All rights reserved.

    Routine photography of all patients admitted to the West of Scotland Regional Burns Unit was introduced in 2003. To date, there are few burns units to evaluate the usefulness of photographs taken. To assess the usefulness of photographs of patients admitted to the burns unit to various members of the multidisciplinary team. A questionnaire was completed by hospital staff involved in the management of burns patients over a 3-month period. A total of 43 questionnaires were completed. The majority of questionnaires were completed by nursing staff (55%) followed by medical staff (23%); physiotherapy (5%); anaesthetists (7%); theatre staff (5%); students (2%); dietician (2%). About 98% of respondents agreed that photographs were useful overall, particularly for teaching purposes. About 9% disagreed that photographs were useful for assessment due to difficulty in assessing depth of burn. About 72% agreed that the photographs were useful for patient management and improve patient care. About 88% agreed that all patients should have photographs available in future. Advantages of photographs include; moving and handling of patients; patient positioning in theatre; reviewing wound healing and complications. They are useful for assessing site, size and type of burn. Disadvantages include difficulty in assessing depth of burn, technical factors, and unavailability out of hours. Photographs of burns patients are useful overall to all members of the multidisciplinary team.

    1995-08-01

    While severe pain is a constant component of the burn injury, inadequate pain management has been shown to be detrimental to burn patients. Pain-generating mechanisms in burns include nociception, primary and secondary hyperalgesia and neuropathy. The clinical studies of burn pain characteristics reveal very clear-cut differences between continuous pain and pain due to therapeutic procedures which have to be treated separately. Some of the main features of burn pain are: (1) its long-lasting course, often exceeding healing time, (2) the repetition of highly nociceptive procedures which can lead to severe psychological disturbances if pain control is inappropriate. Pharmaco-therapy with opioids is the mainstay for analgesia in burned patients, but non-pharmacological techniques may be useful adjuncts. Routine pain evaluation is mandatory for efficient and safe analgesia. Special attention must be given to pain in burned children which remains too often underestimated and undertreated. More educational efforts from physicians and nursing staff are necessary to improve pain management in burned patients.

    An outbreak of chickenpox that occurred at the Burns Repair Surgery Unit, Department of Children's Surgery, Hospital R. del Río, between June and November, 1975, is reported. 27 cases of burned children were studied, including analysis of correlations of the stages and outcome of the disease (varicela), the trauma (burns) and the graft (repair surgery). As a result, the authors emphasize the following findings: 1. Burns and their repair are not aggravating factors for varicella. In a small number of cases the exanthema looked more confluent in the graft surgical areas and in the first degree burns healing spontaneously. 2. Usually there was an uneventful outcome of graft repair surgery on a varicella patient, either during the incubation period, the acme or the convalescence. 3. The fact that the outmost intensity of secondary viremia of varicella occurs before the onset of exanthemia, that is, during the late incubation period, is confirmed.

    Full Text Available Burning mouth syndrome (BMS is multifactorial in origin which is typically characterized by burning and painful sensation in an oral cavity demonstrating clinically normal mucosa. Although the cause of BMS is not known, a complex association of biological and psychological factors has been identified, suggesting the existence of a multifactorial etiology. As the symptom of oral burning is seen in various pathological conditions, it is essential for a clinician to be aware of how to differentiate between symptom of oral burning and BMS. An interdisciplinary and systematic approach is required for better patient management. The purpose of this study was to provide the practitioner with an understanding of the local, systemic, and psychosocial factors which may be responsible for oral burning associated with BMS, and review of treatment modalities, therefore providing a foundation for diagnosis and treatment of BMS.

    The face is a frequent site of burn, but prevalence rates vary and reports are often limited to one healthcare setting. We examined the incidence of facial burns in the Netherlands in Emergency Departments (ED), hospitals and burn centres. Additionally, we identified which patient, injury and burn-related characteristics were predictors of facial burns, facial surgery and facial reconstruction in burn centres. A retrospective, observational study was conducted including data from the Dutch Injury Surveillance System, the National Hospital Discharge Register and burn centres in a 5-year period (2003-2007). Facial burn incidences per 100,000 were 15.1 for ED visits, 1.3 for hospital admissions and 1.4 for burn centre admissions. A total of 2691 patients were admitted to Dutch burn centres; 47.5% (n=1277) had facial burns of which 20.5% received primary facial surgery and 5.3% received facial reconstruction in follow-up. Predictors of facial burns and facial surgery were identified. Predictors of facial reconstructive surgery were burns to the neck (ventral), fire/flame burns and number of facial surgeries in the acute phase of the burn. One in five patients with facial burns admitted to a Dutch burn centre received primary facial surgery and 1 in 20 received facial reconstructive surgery within a follow-up of minimum 2 years.

    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.

    2016-01-07

    The high burden of burn injuries in South Africa (SA) requires surgeons skilled in burn care. However, there are few dedicated burn surgeons and properly equipped units or centres. To quantify the involvement of surgeons in burn care in SA hospitals, identify factors that attract surgeons to pursue burn care as a career and deter them from doing so, and understand the challenges of hospitals treating burn patients around the country. This was a prospective, qualitative study. Questionnaires were handed out at the South African Burn Society Congress in September 2013 and a trade symposium in March 2014. One hundred questionnaires were handed out, and there was a 70% response rate. Twenty-six (39%) of the respondents had a specialist surgical qualification. Only half the units had registrars (48%) and interns (51%) on their staff. Only 30% of the respondents were dedicated to burn care alone, the majority being involved on a part-time basis. The most common factor respondents suggested was needed to recruit future burn care providers, cited by 76%, was better facilities and resources. Other factors included training and skills development (59%), subspecialist training (55%), development of a diploma in burn care (52%), development of research (52%) and healthcare worker psychological support (45%). We have demonstrated that current workforce resources for burn care are inadequate, the major deficit being lack of training and the resource-restricted environment. This survey provides basic information towards workforce planning, which can be used to inform the necessary strategic decisions.

  10. Burning mouth and saliva.

    2002-01-01

    Stomatodynia is the complaint of burning, tickling or itching of the oral cavity, and can be associated with other oral and non-oral signs and symptoms. However, the oral mucosa often appears normal, with no apparent underlying organic cause to account for the symptomatology. The etiology is unknown, though evidence points to the participation of numerous local, systemic and psychological factors. Among the local factors, saliva may play an important role in the symptoms of burning mouth. Saliva possesses specific rheological properties as a result of its chemical, physical and biological characteristics - these properties being essential for maintaining balanced conditions within the oral cavity. Patients with burning mouth present evidence of changes in salivary composition and flow, as well as a probable alteration in the oral mucosal sensory perception related particularly to dry mouth and taste alterations. On the other hand, alterations in salivary composition appear to reflect on its viscosity and symptomatology of burning mouth. Saliva is a field open to much research related to burning mouth, and knowledge of its properties (e.g., viscosity) merits special attention in view of its apparent relationship to the symptoms of burning mouth. The present study describes our clinical experience with burning mouth, and discusses some of the aspects pointing to salivary alterations as one of the most important factors underlying stomatodynia.

  11. A review of the evidence for threshold of burn injury.

    2017-12-01

    Burn injury is common and depth is one measure of severity. Although the depth of burn injury is determined by many factors, the relationship between the temperature of the injurious agent and exposure duration, known as the time-temperature relationship, is widely accepted as one of the cornerstones of burn research. Moritz and Henriques first proposed this relationship in 1947 and their seminal work has been cited extensively. However, over the years, readers have misinterpreted their findings and incorporated misleading information about the time-temperature relationship into a wide range of industrial standards, burn prevention literature and medicolegal opinion. The purpose of this paper is to present a critical review of the evidence that relates temperature and time to cell death and the depth of burn injury. These concepts are used by researchers, burn prevention strategists, burn care teams and child protection professionals involved in ascertaining how the mechanism of burning relates to the injury pattern and whether the injury is consistent with the history. This review explores the robustness of the currently available evidence. The paper summarises the research from burn damage experimental work as well as bioheat transfer models and discusses the merits and limitations of these approaches. There is broad agreement between in vitro and in vivo studies for superficial burns. There is clear evidence that the perception of pain in adult human skin occurs just above 43°C. When the basal layer of the epidermis reaches 44°C, burn injury occurs. For superficial dermal burns, the rate of tissue damage increases logarithmically with a linear increase in temperature. Beyond 70°C, rate of damage is so rapid that interpretation can be difficult. Depth of injury is also influenced by skin thickness, blood flow and cooling after injury. There is less clinical evidence for a time-temperature relationship for deep or subdermal burns. Bioheat transfer models are

    Full Text Available Background: Damages caused by scald burns are common and can cause severe complications and death. The purpose of this study was to define risk groups and then methods of prevention and treatment is designed to fit. Methods: Data for this retrospective study of hospitalized patients in Shahid Motahari Hospital in Tehran from 2007-2011 were compiled. Data including age, sex, cause of burn, and degree of burn and ultimate fate of the victims were collected from scald burns. Burns caused by boiling water and hot food (Scald , in two age groups : 12 and under 12 years ( children and more than 12 years ( adults were compared in terms of statistics . Results: A total of 1150 patients consisting of males (57.9% and females (42.1% were studied. The most common age was 1 year old and 50% of patients were under 3 years of age. 87.9% burned with boiling water and 12.1% had experienced burns with hot food. Incentive to burn was 0.3% cross burning and 99.7% incident. A maximum number of burns in children 12 years and younger males (42.1% and a minimum number in men over 12 years (15.7% were observed. Mean percentage of burns was 11% in over 12 years group and 30.9% in 12 and under 12 years group. The average hospital stay was 11.4 days and the mortality rate was 4.8%. The final status of the patients was as fallows: full recovery 904 cases (78.6%, partial recovery 134 (11.7%, clearance with personal consent 41 (3.6%, death 55 (4.8% and 16 cases (3.1% were among other reasons. Conclusion: In general it can be said, scald burns incidence in individuals aged 12 and younger were more than the older ones and the mean of burns was lower in individuals with over 12 years old. There was a sexual preference for males under 12 years. Mortality rate in the two groups has not any statistically significant difference. There was no statistically significant association between sex and mortality rate. Some of our findings are depending on cultural, social and economic

    Small and moderate scalds in toddlers are still the most frequent thermal injuries the pediatric surgeons have to face today. Over the last years, surgical treatment of these patients has changed in many aspects. Due to new dressing materials and new surgical treatment strategies that are particularly suitable for children, today, far better functional and aesthetic long-term results are possible. While small and moderate thermal injuries can be treated in most European pediatric surgical departments, the severely burned child must be transferred to a specialized, ideally pediatric, burn center, where a well-trained multidisciplinary team under the leadership of a (ideally pediatric) burn surgeon cares for these highly demanding patients. In future, tissue engineered full thickness skin analogues will most likely play an important role, in pediatric burn as well as postburn reconstructive surgery.

    Since the introduction of applications (apps) for smartphones, the popularity of medical apps has been rising. The aim of this review was to demonstrate the current availability of apps related to burns on Google's Android and Apple's iOS store as well as to include a review of their developers, features, and costs. A systematic online review of Google Play Store and Apple's App Store was performed by using the following search terms: "burn," "burns," "thermal," and the German word "Verbrennung." All apps that were programmed for use as medical apps for burns were included. The review was performed from 25 February until 1 March 2014. A closer look at the free and paid calculation apps including a standardized patient was performed. Four types of apps were identified: calculators, information apps, book/journal apps, and games. In Google Play Store, 31 apps were related to burns, of which 20 were calculation apps (eight for estimating the total body surface area (TBSA) and nine for total fluid requirement (TFR)). In Apple's App Store, under the category of medicine, 39 apps were related to burns, of which 21 were calculation apps (19 for estimating the TBSA and 17 for calculating the TFR). In 19 out of 32 available calculation apps, our study showed a correlation of the calculated TFR compared to our standardized patient. The review demonstrated that many apps for medical burns are available in both common app stores. Even free available calculation apps may provide a more objective and reproducible procedure compared to manual/subjective estimations, although there is still a lack of data security especially in personal data entered in calculation apps. Further clinical studies including smartphone apps for burns should be performed. Copyright © 2014 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.

    Ball lightning is a rare physical phenomenon, which is not yet completely explained. It is similar to lightning but with different, peculiar characteristics. It can be considered a mix of fire and electricity, concentrated in a fireball with a diameter of 20-cm that most commonly appears suddenly, even in indoor conditions, during a thunderstorm. It moves quickly for several meters, can change direction, and ultimately disappears. During a great storm, a 28-year-old man and his 5-year-old daughter sustained burn wounds after ball lightning came from the outdoors through a chimney. These two patients demonstrated signs of fire and electrical injuries. The father, who lost consciousness, sustained superficial second-degree burn wounds bilaterally on the zygomatic area and deep second-degree burn wounds on his right hand (total body surface area, 4%). His daughter demonstrated superficial second-degree burn wounds on the left part of the face and deep second-degree and third-degree burn wounds (total body surface area, 30%) on the left neck, both upper arms, and the back. In this article, the authors report the first two cases of burn injuries resulting from ball lightning contact indoors. The literature on this rare phenomenon is reviewed to elucidate the nature of ball lightning. Emphasis is placed on the nature of injuries after ball lightning contact, the therapy used, and the long-term complications.

    Hand burns are common in the pediatric population. Optimal hand function is a crucial component of a high-quality survival after burn injury. This can only be achieved with a coordinated approach to the injuries. The aim of this study was to review the management algorithm and outcomes of pediatric hand burns at our institution. In total, 70 children fulfilling our study criteria were treated for a burn hand injury in our Burn Care Center between January 2008 and May 2013. 14 of the 70 pediatric patients underwent surgery because of the depth of the hand burns. The management algorithm depending on the depth of the burn is described. Two patients underwent correction surgery due to burn contractures later. For a successful outcome of the burned hand, the interdisciplinary involvement and cooperation of the plastic and pediatric surgeon, hand therapist, burn team, patient and their parents are crucial.

    Currently, there are few studies on candidaemia in the severely burned patient. These patients share the same risk factors for invasive fungal infections as other critically ill patients, but have certain characteristics that make them particularly susceptible. These include the loss of skin barrier due to extensive burns, fungal colonisation of the latter, and the use of hydrotherapy or other topical therapies (occasionally with antimicrobials). In addition, the increased survival rate achieved in recent decades in critically burned patients due to the advances in treatment has led to the increase of invasive Candida infections. This explains the growing interest in making an earlier and more accurate diagnosis, as well as more effective treatments to reduce morbidity and mortality of candidaemia in severe burned patients. A review is presented on all aspects of the burned patient, including the predisposition and risk factors for invasive candidiasis, pathogenesis of candidaemia, underlying immunodeficiency, local epidemiology and antifungal susceptibility, evolution and prognostic factors, as well as other non-Candida yeast infections. Finally, we include specific data on our local experience in the management of candidaemia in severe burned patients, which may serve to quantify the problem, place it in context, and offer a realistic perspective.

    Full Text Available Objective: Psychiatric rehabilitation has gained significance owing to improved healthcare facilities for burn injuries and decreased mortality/ morbidity rates. Burn traumas may result in psychiatric signs such as denial, anger, guilt, confusion, disgrace, anxiety, distress, and nervousness. Psychiatric disorders such as delirium, depression, anxiety, post-traumatic stress disorder, and sexual problems can also be encountered. Therefore, it is necessary to look for these signs and disorders through regular sessions with burn patients and appropriate psychometric tests. This study aims at examining the process of psychological rehabilitation for burn patients in light of the current literature. Material and Methods: This study has been carried out in the light of the main and current literature review. The study intends to put forth the data observed in the course of the psychological diagnosis, treatment and rehabilitation of burn patients. The study has been conducted in accordance with the Helsinki Declaration Guidelines. Results: Treatment and rehabilitation process requires a multidisciplinary teamwork that consists of physicians, dieticians, psychologists, social service specialists, and other healthcare workers who can meet the needs of burn patients and their families. It is necessary for the team to contribute both to the hospitalization process and the social environment of the patients and their families. Conclusion: It is observed that the quality of life of these patients can be considerably improved with the effective assessment of psychiatric signs that occur during or after the injury and with appropriate treatment methods.

    To compare hospitalisations for diabetes mellitus (DM) after injury experienced by burn patients, non-burn trauma patients and people with no record of injury admission, adjusting for socio-demographic, health and injury factors. Linked hospital and death data for a burn patient cohort (n=30,997) in Western Australia during the period 1980-2012 and two age and gender frequency matched comparison cohorts: non-burn trauma patients (n=28,647); non-injured people (n=123,399). The number of DM admissions and length of stay were used as outcome measures. Multivariate negative binomial regression was used to derive adjusted incidence rate ratios and 95% confidence intervals (IRR, 95%CI) for overall post-injury DM admission rates. Multivariate Cox regression models and hazard ratios (HR) were used to examine time to first DM admission and incident admission rates after injury discharge. The burn cohort (IRR, 95%: 2.21, 1.80-2.72) and other non-burn trauma cohort (IRR, 95%CI: 1.63, 1.24-2.14) experienced significantly higher post-discharge admission rates for DM than non-injured people. Compared with the non-burn trauma cohort, the burn cohort experienced a higher rate of post-discharge DM admissions (IRR, 95%CI: 1.40, 1.07-1.84). First-time DM admissions were significantly higher during first 5-years after-injury for the burn cohort compared with the non-burn trauma cohort (HR, 95%CI: 2.00, 1.31-3.05) and non-injured cohort (HR, 95%CI: 1.96, 1.46-2.64); no difference was found >5years (burn vs. non-burn trauma: HR, 95%CI: 0.88, 0.70-1.12; burn vs non-injured: 95%CI: 1.08 0.82-1.41). No significant difference was found when comparing the non-burn trauma and non-injured cohorts (0-5 years: HR, 95%CI: 1.03, 0.71-1.48; >5years: HR. 95%CI: 1.11, 0.93-1.33).

    Burns are physically, psychologically and economically challenging injuries, and the factors leading to them are many and under-studied. The aim of the current study was to assess level of anxiety, depression and self-esteem in burn patients, and look at various burn-related variables that affect them. This cross-sectional study included 100 patients with burn injuries admitted to a tertiary care private hospital in an urban metropolis in India. The patients were assessed for anxiety, depression and self-esteem using the Hamilton anxiety rating scale, Hamilton depression rating scale and Rosenberg self-esteem scale respectively. Assessment was carried out within 2-8 weeks of injury following medical stabilization. The data was tabulated and statistically analyzed. The study sample was predominantly male (54%), married (69%), with a mean age of 34.1 ± 10.8 years. Accidental burns (94%) were the most common modality of injury. The majority (46%) suffered burns involving 20-59% total body surface area (TBSA), and facial burns were present (57%). No significant association was found between TBSA and anxiety, depression or self-esteem, and the same was true for facial burns. Deep burns, however, were significantly associated with anxiety (p=0.03) and depression (p=0.0002). High rates of anxiety and depression are associated with burn injuries and related to burn depth. Adjustment and recovery in these patients depends on various other factors like the patient's psychological status, nature/extent of the injury and ensuing medical care. Further research is warranted to reveal the magnitude and predictors of psychological problems in burn patients.

    The cost of the treatment of burns is high especially in self-inflicted burns with prolonged treatment. We performed a retrospective review of the self-inflicted burns at our regional burns centre to determine the costs incurred in their management and to identify factors which could reduce the financial burden in the future. The data was collected retrospectively of all the inpatient and outpatient self-inflicted burns presenting to our regional burns centre in the year 2011. Twenty one patients (out of a total of 870 patients) presented with self-inflicted burns to our centre in 2011. Five (23.8%) were major burns with an average of 53.2% Total Body Surface Area (TBSA) and 16 (76.2%) were minor burns with an average of 0.5% TBSA. 11 (52.4%) patients had flame burns including 4 self-immolation burns. The mortality rate was 4.8% (n=1). Five (23.8%) patients underwent surgical treatment. Seven (33.3%) patients were treated in intensive care and with average stay of 46.85 days. Critical care and theatre attendances made up most of the costs with average ICU stay per patient calculated at £313,131/day. The total cost of all 21 patients was £1,581,856. Burns are preventable injuries, early detection and intervention in patients with propensity to self-inflict burns can possibly reduce the costs of treatment in the future.

    Each year, approximately 265,000 deaths occur due to burns on a global scale. In Bangladesh, around 173,000 children under 18 sustain a burn injury. Since most epidemiological studies on burn injuries in low and middle-income countries are based on small-scale surveys or hospital records, this study aims to derive burn mortality and morbidity measures and risk factors at a population level in Bangladesh. A household survey was conducted in seven rural sub-districts of Bangladesh in 2013 to assess injury outcomes. Burn injuries were one of the external causes of injury. Epidemiological characteristics and risk factors were described using descriptive as well as univariate and multivariate logistic regression analyses. The overall mortality and morbidity rates were 2 deaths and 528 injuries per 100,000 populations. Females had a higher burn rate. More than 50% of injuries were seen in adults 25 to 64 years of age. Most injuries occurred in the kitchen while preparing food. 88% of all burns occurred due to flame. Children 1 to 4 years of age were four times more likely to sustain burn injuries as compared to infants. Age-targeted interventions, awareness of first aid protocols, and improvement of acute care management would be potential leads to curb death and disability due to burn injuries.

    Full Text Available Burning mouth disorder (BMD is a burning or stinging sensation affecting the oral mucosa, lips and/or tongue, in the absence of clinically visible mucosal lesions. There is a strong female predilection, with the age of onset being approximately 50 years. Affected patients often present with multiple oral complaints, including burning, dryness and taste alterations. The causes of BMD are multifactorial and remain poorly understood. Recently, there has been a resurgence of interest in this disorder with the discovery that the pain of burning mouth syndrome (BMS may be neuropathic in origin and originate both centrally and peripherally. The most common sites of burning are the anterior tongue, anterior hard palate and lower lip, but the distribution of oral sites affected does not appear to affect the natural history of the disorder or the response to treatment BMS may persist for many years. This article provides updated information on BMS and presents a new model, based on taste dysfunction, for its pathogenesis.

    2008-01-01

    Although burn injuries during pregnancy are considered relatively rare, the exact incidence is not known. Multiple factors influence morbidity and mortality resulting from burn injuries during pregnancy. These factors include the depth and size of the burn, the woman's underlying health and age, and the estimated gestational age of the fetus. Associated inhalation injury and development of other significant secondary complications also influence maternal and fetal outcomes. Successful burn care requires a team approach in which almost every healthcare discipline is represented. Initial care is almost always provided by a specially trained emergency medical team in an out-of-hospital setting. During this phase, the ability of the team to communicate with emergency hospital personnel facilitates appropriate clinical management at the scene. In addition, continued communication regarding the woman's status and responses to treatment allows critical care specialists within the hospital to ensure that necessary personnel and resources are available when the patient arrives. From the time the pregnant woman is admitted to a hospital for additional acute and critical care through the extensive process of rehabilitation from burn injuries, providing care often evokes strong emotions and requires specialized skills to achieve the most positive outcomes.

  3. Hand chemical burns.

    2015-03-01

    There is a vast and ever-expanding variety of potentially harmful chemicals in the military, industrial, and domestic landscape. Chemical burns make up a small proportion of all skin burns, yet they can cause substantial morbidity and mortality. Additionally, the hand and upper extremity are the most frequently involved parts of the body in chemical burns, and therefore these injuries may lead to severe temporary or permanent loss of function. Despite this fact, discussion of the care of these injuries is sparse in the hand surgery literature. Although most chemical burns require only first response and wound care, some require the attention of a specialist for surgical debridement and, occasionally, skin coverage and reconstruction. Exposure to certain chemicals carries the risk of substantial systemic toxicity and even mortality. Understanding the difference between thermal and chemical burns, as well as special considerations for specific compounds, will improve patient treatment outcomes.

    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 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

    Full Text Available Burn injuries and their subsequent treatment cause one of the most excruciating forms of pain imaginable. The psychological aspects of burn injury have been researched in different parts of the world, producing different outcomes. Studies have shown that greater levels of acute pain are associated with negative long-term psychological effects such as acute stress disorder, depression, suicidal ideation, and post-traumatic stress disorder for as long as 2 years after the initial burn injury. The concept of allostatic load is presented as a potential explanation for the relationship between acute pain and subsequent psychological outcomes. A biopsychosocial model is also presented as a means of obtaining better inpatient pain management and helping to mediate this relationship.

    Full Text Available 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.

    Summary Aim To determine the epidemiology and clinical presentation, and any contributing factors responsible for burns and outcome of care in Kuwait over the 5-yr period January 2006 to December 2010. Patients and methods. The study reviewed 1702 burn patients admitted over the study period to the Saud Al Babtain Burns, Plastic and Reconstructive Surgery Center, Kuwait. Patient characteristics, including age, sex, type of burn, nationality, total body surface area (TBSA) burn, hospital stay in days, and mortality were recorded. Results. Seventy-one per cent of the 1702 burn patients admitted were males; 540 were children. The majority of patients (64%) had less than 15% TBSA burns and only 14% had more than 50% TBSA burns. Flame burns were the most common cause of burn injuries (60%), followed by scalds (29%). Scalds were most common in children. The mortality rate was 5.75%. Flame burn was the leading cause of mortality. Lethal dose 50 (% TBSA at which a certain group has a 50% chance of survival) for adults (16-40 yr) and for the elderly (>65 yr) was 76.5% and 41.8% TBSA respectively. Conclusion. Burn injury is an important public health concern and is associated with high morbidity and mortality. Flame and scald burns are commonly a result of domestic and occupational accidents and they are preventable. Effective initial resuscitation, infection control, and adequate surgical treatment improve outcomes. PMID:23766750

    2013-09-01

    Aerosols from biomass burning perturb Earth’s climate through the direct radiative effect (both scattering and absorption) and through influences on cloud formation and precipitation and the semi-direct effect. Despite much effort, quantities important to determining radiative forcing such as the mass absorption coefficients (MAC) of light-absorbing carbon, secondary organic aerosol (SOA) formation rates, and cloud condensation nuclei (CCN) activity remain in doubt. Field campaigns in northern temperate latitudes have been overwhelmingly devoted to other aerosol sources in spite of biomass burning producing about one-third of the fine particles (PM2.5) in the U.S.

  13. An assessment of burn care professionals' attitudes to major burn.

    2008-06-01

    The resuscitation of severe burn remains a controversial area within the burn care profession. There is ongoing debate as to what percentage burn is associated with a sufficient quality of life to support initial resuscitation efforts. We conducted a survey of delegates at the 39th Annual Meeting of the British Burns Association (2005), regarding attitudes towards resuscitation following major burns. Respondents were asked the maximum percentage total body surface area (TBSA) burn beyond which they would not wish to be resuscitated. They were also asked what maximum TBSA they perceived to be commensurate with an acceptable quality of life (QOL). One hundred and forty three of 300 delegates responded to the questionnaire. Thirty three percent of respondents would not wish to be resuscitated with 50-75% TBSA burns or greater. A further 35% would not wish to have life-sustaining intervention with 75-95% TBSA burns or greater. The remaining 32% indicated that they would not want resuscitation with TBSA burns>95%. Regardless of TBSA affected, 16% would not wish resuscitation if they had full thickness facial burns, a further 10% did not want resuscitation if both their hands and faces were affected. Our survey demonstrates the diversity of personal preference amongst burn care professionals. This would suggest that a unifying philosophy regarding the resuscitation of extensive burns will remain elusive.

    Full Text Available Este trabalho experimental objetivou a avaliação do uso da laparoscopia para biópsia hepática em eqüino e o estudo das possíveis alterações clínicas e laboratoriais decorrentes de tal procedimento. Foram utilizados 10 animais, os quais foram submetidos a procedimento cirúrgico em posição quadrupedal, por abordagem pelo flanco direito, no 17º espaço intercostal, após jejum alimentar e hídrico de 36 e 18 horas respectivamente. A avaliação pós-operatória constou de exame físico diário e colheita de amostras de sangue seriadas. O procedimento possibilitou inspeção dos órgãos e estruturas anatômicas localizados dorsalmente à direita da cavidade abdominal, favorecendo a escolha do local de biópsia hepática. Não foram observadas alterações no exame físico dos animais. Os exames hematológicos e de função hepática não apresentaram alterações significativas. Concluiu-se que o emprego da laparoscopia para realização de biópsia hepática em eqüino é simples, eficaz e seguro.The purpose of this research was to evaluate the use of laparoscopy in obtaining hepatic biopsy in horses and to determine a possible clinical and laboratorial changes related to the procedure. Ten animals were submitted to 36 hours of fastening and 18 hours of water deprivation and then operated in the standing position, through a right flank approach at the level of the 17th intercostal space. Post-operative evaluation consisted of daily physical examination and seriated blood sampling. The procedure allowed for wide visualization of the viscera and anatomical structures located on the right side of the abdominal cavity, favouring the choice of the spot for hepatic biopsy collection. No changes were noted in the physical state of the animals and alterations in hemogram and hepatic function tests were not statistically significant. It was concluded that laparoscopy is a simple, effective and safe technique for obtaining hepatic biopsy

Objective: To check alterations in lipid profile after burn injury. Materials and Method: It was cross sectional study which was carried out on 250 burns patients of both sex, with an age group of 18-45 years, and varying burns percentage of 20-80% of total body surface area (TBSA. Serum cholesterol, serum LDL, serum HDL and serum triglyceride level were measured on XL-640 fully-auto biochemical analyser. Serum LDL and HDL were measured by Accelerator Selective Detergent Method. Serum cholesterol and triglyceride were measured by Trindor’s method. Results: Results showed decrease in serum cholesterol, serum LDL and serum HDL, while increase in serum triglyceride level in burns patients compared to normal subjects. Conclusion: This study clearly showed the importance of measuring serum cholesterol, TG, LDL and HDL in burn patients and targeting changes that occur in their levels along the burns course, which may have beneficial effect in protection from organ damage, increasing survival rates and improving burn outcome.

    To evaluate the diversity and antifungal susceptibilities of Candida isolates from wounds and blood of burn victims, and the associated mortality rates compared with those of controls without candidaemia. We performed a nested case-control study within a database of clinical data for all patients admitted to our burn unit from January 2001 to December 2005. Each candidaemic patient was compared with two matched controls. Bloodstream cultures were performed if the core temperature was >39 degrees C, and three sites were cultured weekly for fungal identification (burn wound, pharynx, urinary tract). At least one episode of candidaemia was diagnosed among 20 of 851 persons admitted during the study period. Isolates in bloodstream infection were Candida albicans (65%), C. parapsilosis (25%) and C. tropicalis (10%). The median time between admission and onset of candidaemia was greater with C. albicans infection (42.6+/-31 days) than with infection by other yeasts (18+/-12 days). Candidaemia was associated with more extensive burn and longer duration of hospital stay but with similar mortality, compared with controls. Candidaemia in burn cases is mostly due to fluconazole-susceptible C. albicans and is not associated with increased mortality.

    2001-01-01

    This study tested the efficacy of 2 brief cognitive interventions in supplementing regular medical treatment for pain during burn dressing change. Forty-two burn inpatients were randomly assigned to 3 groups: sensory focusing, music distraction, and usual care. Patients reported pain, pain relief satisfaction with pain control, and pain coping strategies. The sensory focusing group reported greater pain relief compared to the music distraction group and a reduction in remembered pain compared to the usual care group, although group differences were not observed on serial pain ratings. In addition, after controlling for burn size and relevant covariates, regression analyses indicated that catastrophizing predicted pain, memory for pain, and satisfaction with pain control. Refinement of the sensory focusing intervention is warranted to reduce catastrophic thinking and improve pain relief

    Key Clinical Message Eschar formation is a potential sequela of burn injuries. Definitive management may include escharectomy and eschar debridement. After eschar removal, the wound can be covered with a skin graft or reepithelialization. For prolonged refractory eschar on the fingertips, topical use of rb?bFGF after debridement can achieve an optimal outcome.

    The aim of the study is to understand the incidence of burns among outpatients and inpatients of Taiwan in 2010. Characteristics of the burned patients were also studied in terms of gender, age, burn sites, burn degree, reconstructive surgical treatment, as well as which specialty and medical facility they are treated in. Burned patients were identified from the 1,000,000-person cohort dataset sampled from the Taiwan National Health Insurance database. Ones who had been hospitalized with discharge diagnoses related to burns were categorized as inpatients and others who had only ambulatory visits and emergency room visits were classified as outpatients. 7630 burn-injury patients were found, presenting an annual incidence of burns as 670.8/10(5) in males (n=3303) and 852.5/10(5) in females (n=4327). Only 3.4% (156 males and 107 females) of them were hospitalized. Higher incidence of burns were found in females and young children, while males and the elderly tended to have more severe burns, based on high-degree burns, admission rate, and incidence of hospitalizations for burns. This is a population-based study demonstrating the epidemiology of burns among outpatients and inpatients in Taiwan, leading us closer to the reality of burns treated in different settings of medical facilities.

    2018-02-01

    To describe parents' perceived quality of pediatric burn care and evaluate factors associated with differences in perceived quality among parents. 62 parents of children with burns were recruited on a Swedish national basis 0.8 to 5.6years after the child's injury. Measures were an adaptation of the Quality of Care Indices - Parent questionnaire consisting of 8 subscales and one overall question, the Impact of Event Scale -Revised, Montgomery Åsberg Depression Rating Scale, and Injury-specific fear-avoidance. Ratings of quality of care were high, especially regarding Staff Attitudes, Medical Treatment, and Caring Processes. Overall satisfaction rated from 1 to 10 was on average 9.1 (SD=1.2). Overall satisfaction and specific indices of Quality of care were not associated with burn severity, parent gender, or parent age. However, Quality of care was associated with current symptoms of posttraumatic stress and depression, and parents of girls expressed being less satisfied with Participation. Parents' perceived quality of care is associated with psychological health, but not with characteristics of the child's injury or age. The results suggest that burn care can improve by involving parents of girls more and by being more attentive towards parents who themselves appear stressed or worried. Copyright © 2017 The Authors.

    Full Text Available Com o propósito de avaliar a segurança, a eficácia diagnóstica da biópsia pulmonar e comparar a possível ocorrência de complicações decorrentes da técnica, entre bezerros sadios e com broncopneumonia induzida, utilizaram-se dez bezerros (G1 sadios e vinte bezerros portadores de broncopneumonia, divididos em quatro grupos de cinco bezerros (G2 a G5, os quais foram biopsiados 12, 24, 48 e 72 horas após a inoculação com Mannheimia haemolytica, respectivamente. A presença de crepitação grossa, som submaciço à percussão e as alterações radiográficas auxiliaram no diagnóstico da broncopneumonia e localizaram a área pulmonar a ser biopsiada nos grupos G2 a G5. As alterações microscópicas, visualizadas nos animais do grupo G2 a G5, foram as de broncopneumonia fibrinopurulenta. Nos bezerros do grupo G1 as alterações relacionadas à técnica foram: tosse, epistaxe, dispneia mista, taquipneia e taquicardia. Cinco (25% bezerros com broncopneumonia desenvolveram hemotórax após a biópsia e as alterações relacionadas à técnica foram: taquipneia, taquicardia, tosse, dispneia mista, apatia, mucosas pálidas e decúbito. Conclui-se que a biópsia pulmonar permite o diagnóstico de broncopneumonia em bezerros, contudo as complicações decorrentes da técnica limitam o seu uso apenas nas situações em que os métodos convencionais não tenham possibilitado o diagnóstico.

    Coal-derived liquids are a new and vital class of industrial compounds, but have thermodynamic properties that are largely unknown and, presently, unpredictable. The objective of this research is to measure one of the most important thermodynamic properties, the enthalpy, for representative coal-derived liquids over the pressure and temperature regions most likely to be encountered in both liquefaction and processing systems. Experimental measurements were made on a distillate from a coal-derived liquid sample produced with the Synthoil process. The measurements extend from 155 to 742/sup 0/F at pressures of 150, 200, 500, 1000, and 1500 psia. Enthalpy measurements were also started on a naphtha cut from a coal-derived liquid produced by the SRC-I process. These naphtha measurements are approximately 60 percent complete.

    Objectives: We report a rare case of burns following the use of automated air-fresheners. Methods: We present a case report with a brief overview of the literature relating to burns associated with air-fresheners. The mechanism and treatment of these types of injuries are also described. Results: A 44 year-old female was admitted under the care of the burns team following burns secondary to an exploding air-freshener canister. The patient sustained burns to the face, thorax and arms resulting in a seven-day hospital admission. The burns were treated conservatively. Conclusions: To our knowledge this is one of the few documented cases of burns as a result of air-fresheners. As they become more ubiquitous, we anticipate the incidence of such cases to increase. As such, they pose a potential public health concern on a massive scale. PMID:22174972

    Objective: To analyze the epidemiological characteristics of the hospitalized patients with electrical burns in Institute of Burns of Tongren Hospital of Wuhan University & Wuhan Third Hospital (hereinafter referred to as Institute of Burns of Wuhan Third Hospital), so as to provide reference for the prevention and treatment of electrical burns. Methods: Medical records of all hospitalized burn patients in Institute of Burns of Wuhan Third Hospital from January 2004 to December 2016 were collected. Genders, ages, social categories, seasons of injury, total burn areas, depths of wounds, electrical voltages of injury, sites of wound, treatment methods, amputation rates, lengths of hospital stay, operation costs, hospitalization costs, and treatment outcomes of the electrical burn patients were collected. Treatment methods, lengths of hospital stay, operation costs, and hospitalization costs of the thermal burn patients were collected and compared with those of the electrical burn patients. Electrical voltages of injury, amputation rates, operation costs, hospitalization costs, and treatment outcomes were compared and analyzed between the electrical contact burn patients and the electrical arc burn patients. Data were processed with Chi-square test and Wilcoxon rank-sum test. Results: During the 13 years, 23 534 burn patients were admitted to Institute of Burns of Wuhan Third Hospital, among whom 2 133 (9.1%) were with electrical burns, without obvious variation in admission number of electrical burn patients every year. There were 1 418 patients (66.5%) with electrical contact burns and 715 patients (33.5%) with electrical arc burns. The ratio of male to female was 11.2∶1.0 among the electrical burn patients with known genders. The proportions of three age groups of more than 20 years old and less than or equal to 30 years old, more than 30 years old and less than or equal to 40 years old, and more than 40 years old and less than or equal to 50 years old were

  13. Chemical Debridement of Burns

    The development of effective, non-toxic (local and systemic) methods for the rapid chemical (enzymatic and non-enzymatic) debridement of third degree burns would dramatically reduce the morbidity and mortality of severely burned patients. Sepsis is still the major cause of death of patients with extensive deep burns. The removal of the devitalized tissue, without damage to unburned skin or skin only partially injured by burning, and in ways which would permit immediate (or very prompt) skin grafting, would lessen substantially the problems of sepsis, speed convalescence and the return of these individuals to society as effective human beings, and would decrease deaths. The usefulness and limitations of surgical excision for patients with extensive third degree burns are discussed. Chemical debridement lends itself to complementary use with surgical excision and has the potential advantage over surgical excision in not requiring anesthesia or a formal surgical operation. The authors' work with the chemical debridement of burns, in particular the use of Bromelain, indicates that this approach will likely achieve clinical usefulness. The experimental studies indicate that rapid controlled debridement, with minimal local and systemic toxicity, is possible, and that effective chemotherapeutic agents may be combined with the Bromelain without either interfering with the actions of the other. The authors believe that rapid (hours) debridement accomplished by the combined use of chemical debriding and chemotherapeutic agents will obviate the possibility of any increase in infection, caused by the use of chemical agents for debridement, as reported for Paraenzyme21 and Travase.39,48 It is possible that the short term use of systemic antibiotics begun just before and continued during, and for a short time after, the rapid chemical debridement may prove useful for the prevention of infection, as appears to be the case for abdominal operations of the clean-contaminated and

    Biomass samples including agricultural waste (rice straw and maize residue) and forest leaf litter were collected from Chiang Mai Province, Thailand for the burning experiment in the self-designed stainless steel chamber to simulate the emissions of PM10. The burning of leaf litter emitted the highest PM10 (1.52±0.65 g kg(-1)). The PM10-bound ions emitted from the burning of rice straw and maize residue showed the same trend, which was K(+)>Cl(-)>SO4(2-)>NH4(+)>NO3(-). However, the emissions from maize residue burning were ~1.5-2.0 times higher than those from the rice straw burning. The ion content emitted from leaf litter burning was almost the same for all ion species. Noticeably, K(+) and Cl(-) concentrations were ~2-4 times lower than those emitted from agricultural waste burning. It can be deduced that K(+) and Cl(-) were highly emitted from agricultural waste burning due to the use of fertilizer and herbicides in the field, respectively. Based on emission values obtained from the chamber, the pollutant emission rate from open burning was calculated. Burned areas in Chiang Mai Province were 3510 and 866 km(2) in 2010 and 2011, respectively. Forest burning was 71-88%, while agricultural land burning accounted for 12-29% (rice field: crop field=1:3) of total burned area. Therefore, emissions of PM10 from open burning in Chiang Mai were 3051 ton (2010) and 705 ton (2011). Major ions emitted from agricultural waste burning were found to be K(+) and Cl(-), while those from forest burning were SO4(2-) and K(+). Copyright © 2013 Elsevier Ltd. All rights reserved.

    Death from fires and burns are the sixth most common cause of unintentional injury death in the United States. More than (3/4) of burn deaths occurring in the United States are in the home. Mobile home fires carry twice the death rate as other dwellings. The aim of the study was to describe the characteristics of deaths and injuries in mobile home fire admitted in a regional Burn Center and to identify possible risk factors. A cross-sectional retrospective study was carried out among all burn patients admitted to a regional Burn Center between January 2002 and December 2004 (3469 patients). The study included patients who suffered a burn injury from a mobile home fire. The demographic characteristics of the patients, location of mobile home, associated inhalation injury, source of fire, comorbidity of the victims, employment status, insurance status, family history of burns, and outcomes of the treatment were incorporated in a data collection record. There were 65 burn patients in mobile home fires admitted to the Burn Center during the studied period. The average age of the patients was 39 years (ranging from 2 to 81 years, SD=16.06), 77% were male, 67% were white, and 79% were the residents in the suburban areas of Georgia, South Carolina, North Carolina, and Florida. The average TBSA of burns was about 21% (ranging from 1 to 63%, SD=17.66), 63% of the patients had associated inhalation, three inhalation injury only, and 69% patients required ventilator support. The average length of stay per TBSA percentage of burn was 1.01 days (P=0.00), controlling for age, preexisting medical comorbidities, and inhalation injury. About 88% of the patients had preexisting medical comorbid conditions, 74% were smokers, 64% reported as alcoholic, and 72% had at least some form of health insurance coverage. In 40% of the cases, the cause of the fire was unknown, 31% were caused by accidental explosions, such as electric, gasoline, or kerosene appliances, and 29% were due to other

    2015-11-01

    The effects of an externally applied electric field are studied on the burning characteristics of a spherically symmetric fuel drop including the structure, mass burning rate and extinction characteristics of the diffusion flame. A reduced three-step chemical kinetic mechanism that reflects the chemi-ionization process for general hydrocarbon fuels has been proposed to capture the production and destruction of ions inside the flame zone. Due to the imposed symmetry, the effect of the ionic wind is simply to modify the pressure field. Our study thus focuses exclusively on the effects of Ohmic heating and kinetic effects on the burning process. Two distinguished limits of weak and strong field are identified, highlighting the relative strength of the internal charge barrier compared to the externally applied field, and numerically simulated. For both limits, significantly different charged species distributions are observed. An increase in the mass burning rate is noticed with increasing field in either limit with negligible change in the flame temperature. Increasing external voltages pushes the flame away from the droplet and causes a strengthening of the flame with a reduction in the extinction Damkhöler number.

    Full Text Available Background: There is no information on the pattern of outcomes among burn patients in relation to clinical aspects in India. Hence, the present study was undertaken in a burn unit to determine selected epidemiological variables, assess the clinical aspects (etiology, extent and anatomical location and finally to analyze the outcomes in cases of burn injury. Materials and Methods: This prospective study was undertaken to analyze the patients admitted to the Burn Unit of Government Medical college Srinagar. The study was carried over a period 2 years from January 2013 to December 2014. Various variables including age and sex distribution, nature of burn injuries, Anatomical location, percentage of total body surface area burnt, depth of burns, Survival of expired patients and mortality were recorded and analyzed. Results: Highest incidence of burns was in the age group between 21 and 40 years; 61% patients were females and 39% were males; majority of our patients had burns in the range of 20 to 40% TBSA (total body surface area; mortality rate in our study was 36.82%; most common site of the burn injury was upper limb(30.19%;among patients who died those with TBSA burn of >60%, 41 to 60% and 31 to 40% succumbed within three, six and nine days respectively. Age ranged from 6 months to 93 years. Mean age of the patients was 31 years. Eighty percent patients belonged to rural areas and 20% belonged to Urban locality. Conclusion: People with low educational qualification should be taught about the proper and safe usage of modern appliances based on electricity, LPG or kerosene. People with psychiatric problems or low intelligence quotient (I.Q should be helped by their care takers in avoiding the burn injuries and also devices with alarms should be used in their households. Fuel or electric devices should be checked by a trained person regularly (e.g once in month to avoid usage of faulty devices.

    The purpose of the study was to identify the basic epidemiological characteristics of burn patients in East Bulgaria, as well as to analyze trends in burns in the region over the last decade. Retrospective data of burn patients treated at Military Hospital-Varna, in the period January 2002-December 2011, was reviewed and statistically interpreted in terms of patients and burn demographics; etiology; place of incidents; hospital stay and mortality. Trends were observed for the entire period and comparative analyses of patients' data were made between two periods: first - 2002-2006 and second 2007-2011. A total of 2627 burn patients, median age 41 years (IQR 9-61) were admitted to our burn unit. For the entire period the most affected age groups were ≤ 4 years (21.6%) and ≥ 65 years (21.1%). Hospitalized patients increased in the second period (n = 1701) compared to the first one (n = 926), while the size of total burn surface area decreased (first period - 9.8% vs. second period - 10.6%). Scald (51%) and flame (23.8%) were the most frequent aetiological agents for both periods. Work related burns reduced in the second period (9.4% vs. 4.9%), while home burns (90.6 vs. 95.1%) increased. Hospital stay declined from 17 days (2002-2006) to 7 days (2007-2011), whereas mortality rate slightly increased (first period - 2.3% vs. second period - 3.6%). Burns remain a significant health problem in Bulgaria. The future preventive actions should take into account the observed changes in burn demographics and target the most vulnerable groups.

    2010-01-01

    Knowledge of the emission source strengths of different (particulate and gaseous) atmospheric constituents is one of the principal ingredients upon which the modeling and forecasting of their distribution and impacts depend. Biomass burning emissions are complex and difficult to quantify. However, satellite remote sensing is providing us tremendous opportunities to measure the fire radiative energy (FRE) release rate or power (FRP), which has a direct relationship with the rates of biomass consumption and emissions of major smoke constituents. In this presentation, we will show how the satellite measurement of FRP is facilitating the quantitative characterization of biomass burning and smoke emission rates, and the implications of this unique capability for improving our understanding of smoke impacts on air quality, weather, and climate. We will also discuss some of the challenges and uncertainties associated with satellite measurement of FRP and how they are being addressed.

    Due to immunosuppression, burn patients are at risk for CMV-infection. By means of a retrospective questionnaire we evaluated the clinical rating and management of CMV-infection in German-speaking burn centers. 41 % of the participating burn centers considered the role of CMV-infection of overall minor importance, 41 % of importance only in intensive care burn patients, 18 % of overall great importance. 70 % of the participating burn centers do not perform CMV-screening at admission. More than 50 % of the participating burn centers consider application of CMV-negative human blood-derived products in CMV-seronegative individuals as essential. At present clinical importance of CMV-infection in burn patients can not be clearly determined. But further prospective studies utilizing recently developed diagnostics seem warranted to the potential influence of CMV-infection on morbidity and mortality in burn patients.

    Most of the acid- burns are due to assault or accidental. The epidemiology of burns is diverse across the world and within a country. We evaluated the epidemiology and outcome of acid-burns in tertiary health care center in Tehran, Iran. This study was retrospective descriptive among patients referred for acid-burn injury that was done in a referral Burn Care Center in Tehran, Iran, during a ten-year period since 2005 to 2014. Patient's data collected by a specially designed check list. The subjects included 37 consecutive patients with various causes of acid burn injury. Descriptive statistics (means with standard deviations or frequency distribution) of sociodemographic variables were computed. The patients' mean age was 31.97±11.02 years. The mean hospitalization period was 18.08±15.25 days. The grade of burn was III in 75.7% patients. Among the acid-burn patients, 64.8% suffered from <20% of total body surface area burn. Most affected part of the body was Head /face/neck 17 (45.9%). Most of the acid-burn occurred from attack (67.6%). Burns mortality rate for this study was identified 8.1% (N=3). The results of this study showed high acid attacks rates. Prevention strategies must be coordinated at national level. So acid-burn patients have to receive the best medical care possible, first locally and then in a specialized center.

    Purpose Civilians living amid conflict are at high-risk of burns. However, the epidemiology of burns among this vulnerable group is poorly understood, yet vital for health policy and relief planning. To address this gap, we aimed to determine the death and disability, healthcare needs and household financial consequences of burns in post-invasion Baghdad. Methods A two-stage, cluster randomized, community-based household survey was performed in May of 2014 to determine the civilian burden of injury from 2003 to 2014 in Baghdad. In addition to questions about cause of household member death, households were interviewed regarding burn specifics, healthcare required, disability, relationship to conflict and resultant financial hardship. Results Nine-hundred households, totaling 5,148 individuals, were interviewed. There were 55 burns, which were 10% of all injuries reported. There were an estimated 2,340 serious burn injures (39 per 100,000 persons) in Baghdad in 2003. The frequency of serious burn injuries generally increased post-invasion to 8,780 burns in 2013 (117 per 100,000 persons). Eight burns (15%) were the direct result of conflict. Individuals aged over 45 years had more than twice the odds of burn injury than children aged less than 13 years (aOR 2.42; 95%CI 1.08 – 5.44). Nineteen burns (35%) involved ≥20% body surface area. Death (16% of burn injuries), disability (40%), household financial hardship (48%) and food insecurity (50%) were common after burn injury. Conclusion Civilian burn injury in Baghdad is epidemic, increasing in frequency and associated with household financial hardship. Challenges of healthcare provision during prolonged conflict were evidenced by a high mortality rate and likelihood of disability after burn injury. Ongoing conflict will directly and indirectly generate more burns, which mandates planning for burn prevention and care within local capacity development initiatives, as well as humanitarian assistance.

    In South Africa, burns are a major public health problem responsible for significant morbidity and long-term physical disability. This is, in part, due to a significant proportion of the urban population living in poorly constructed, combustible accommodation. The presence of co-morbid diseases such as diabetes and malignancy in patients with burns has been associated with a poorer outcome. The impact of other diseases such as HIV has yet to be defined. A retrospective data collection study analysed the 221 patients admitted to Tygerberg Hospital Burns Unit in 2011 and the first six months of 2013. Using hospital records, patient demographic data was collected alongside burn agent, ICU admission, complications, and patient outcome in terms of length of stay and mortality. The most common burn agent was hot liquid (45.7%). A significant proportion of patients were subject to intentional attacks (34.3%). Shack fires and flame accounted cumulatively for 85% of total inhalational burns, the highest rates of admission to ICU (85.5%), the highest rate of complications, as well as 92.3% of all total fatalities. HIV+ patients had a higher mortality (13.3% vs 5%, p=0.22) and a higher complication rate (46.7% vs 30%, p=0.21). There was no difference in length of stay between the HIV+ and HIV- cohort (12days vs. 15.5 days, p=0.916). Burns are a significant yet preventable cause of mortality and morbidity. The rising number of shack fires, responsible for extensive burns and resultant mortality is concerning and indicates urgent attention and action. HIV complicates the recovery from burn and is responsible for an increased rate of in hospital mortality. Copyright © 2016 Elsevier Ltd and ISBI. All rights reserved.

    Burns to the sclera, conjunctiva, cornea, and eyelid are considered ocular burns. Ocular burn injuries are classified by etiologic agents as either chemical injuries (ie, acid, alkali) or radiant energy injuries (ie, thermal, ultraviolet). Chemical injuries to the eye represent one of the true ophthalmic emergencies. While almost any chemical can cause ocular irritation, serious damage generally results from either strongly basic (alkaline) compounds or acidic compounds. Alkali injuries are m...

    The use of cannabis is currently increasing according to U.S. Department of Health and Human Services (HHS). Surprisingly, cannabis use among burn patients is poorly reported in literature. In this study, rates of cannabis use in burn patients are compared with general population. Data from the National Burn Repository (NBR) were used to investigate incidence, demographics, and outcomes in relation to use of cannabis as evidenced by urine drug screen (UDS). Thousands of patients from the NBR from 2002 to 2011 were included in this retrospective study. Inclusion criteria were patients older than 12 years of age who received a drug screen. Data points analyzed were patients' age, sex, UDS status, mechanism of burn injury, total body surface area, length of stay, ICU days, and insurance characteristics. Incidence of cannabis use in burn patients from the NBR was compared against national general population rates (gathered by Health and Human Services) using chi-square tests. Additionally, the burn patient population was analyzed using bivariate analysis and t-tests to find differences in the characteristics of these patients as well as differences in outcomes. Seventeen thousand eighty out of over 112,000 patients from NBR had information available for UDS. The incidence of cannabis use is increasing among the general population, but the rate is increasing more quickly among patients in the burn patient population (P = .0022). In 2002, 6.0% of patients in burn units had cannabis+ UDS, which was comparable with national incidence of 6.2%. By 2011, 27.0% of burn patients tested cannabis+ while national incidence of cannabis use was 7.0%. Patients who test cannabis+ are generally men (80.1%, P 60% of injuries, followed by scalds that are >15%. In comparing cannabis+/- patients, cannabis+ patients are more likely to be uninsured (25.2% vs 17.26%, P burns (TBSA% of 12.94 vs 10.98, P burn units is growing quickly. These patients are younger and are less likely to be insured

  11. Burns, biofilm and a new appraisal of burn wound sepsis.

    Following a burn, the wound may become colonized and septic complications may ensue. Many organisms, commonly isolated from burn wounds produce biofilms, which are defined as a collection of organisms on a surface surrounded by a matrix. Biofilms are associated with development of antibiotic resistant organisms and are refractory to the immune system. The presence of biofilm in the burn wound has not been documented. A study was undertaken using light and electron microscopy to determine the presence of biofilm in the burn wound. Specific stains were used to detect the presence of micro-organisms and associated carbohydrate, a major constituent of the biofilm matrix. A concurrent microbiological study of the burn wound was also carried out. Biofilm was detected in ulcerated areas of the burn wound. Bacterial wound invasion with mixed organisms was also commonly detected. The finding of biofilm in the burn wound has significance in our understanding of burn wound sepsis and supports the evidence for early excision and closure of the burn wound. Due to the recalcitrant nature of biofilm associated sepsis and the difficulty in disrupting biofilm it has implications for the future development of wound care dressings.

    To investigate the geographic distribution and temporal trends of burn admissions in an Australian setting. Health administrative data of all persons hospitalised for a first burn in Western Australia for the period 2000-2012 were used. Crude and standardised incident rates were generated for each region. Maps of crude rates were generated for state regions and postcode-suburbs of Perth, the capital city. Standardised incidence rates were generated for Western Australia, total and regions, and for sub-cohorts defined by age (fire, scalds and contact). Negative binomial regression was used to examine temporal changes and generate incidence rate ratios (IRR) with 95% confidence intervals (CI). Perth had the lowest burn admission rate per population; clusters of suburbs of lower social advantage and higher immigrant settlement were identified as being at high risk. While the highest observed admission rates were found in Kimberley and Goldfields (remote) regions, after adjustment for the regional demographic structures, the Wheatbelt and Mid-West (rural) regions were found to have the highest adjusted rates of burn admissions. Significant annual declines in admission rates were found for the Kimberley, Pilbara and Goldfields (remote regions); however, stable admission rates were identified for all other regions. The Mid-West and Wheatbelt rural regions were found to have the highest risk of burn admissions raising concerns about farming-related injury. Safety awareness and burn prevention strategies need to be continued, with specific attention to these high risk areas, to reduce burn admissions in Western Australia.

    Full Text Available Objective: to describe the effect of music on pain of burn victims during the dressing change. Methods: applied, descriptive, exploratory and quantitative research held in a Burn Treatment Unit from October 2015 to April 2016. The study included 16 burn victims who were divided in three groups: A: patients heard music before dressing; B: patients hear music during dressing; C: patients did not hear music. Results: the average age was 31.8 years (± 14.1 and most of the subjects were male. Lower limbs and trunk were the most affected parts of the body, especially with second-degree burns and which affected an average of 15.8% (± 11.5 of the body surface. There was a predominance of gospel music (50.0%. The music reduced the average heart rate and oxygen saturation, but did not change ventilatory rate. There was a decrease in the average of pain intensity in groups GB (p = 0.0505 and GC (p = 0.0055. During the dressing, the burning was unanimous characteristic for all subjects, in the same manner as verbal reports was the form of manifestation. Conclusion: music proved to be a simple and effective resource in controlling pain in burn victims. Keywords: Burns; Music; Pain.

    Latarjet, Jacques

    2002-12-15

    In 2002, the organisation of burn care is confronted to a great deficiency in burn epidemiological datas. The main mechanisms of hospitalized burns are somehow wellknown in industrialized countries: about 60% scalds and 30% flame burns; as well as the place of occurrence (60% at home, and 20% at work), and the risk groups (3 times more important for the age group 0-4 years old). The incidence of burns needing medical care (all levels) (250/100,000 inh/yr) or hospitalization (15-20/100,000 inh/yr) is much more uncertain. The statistics of Diagnosis Related Groups (DRG), for hospitalized patients will allow in France very shortly to know more about the most rational ways of dispatching and treating them. They already show that only 30% of hospitalized burned patients are treated in specialized facilities.

  15. Reactive burn models and ignition & growth concept

    Energy Technology Data Exchange (ETDEWEB)

    Menikoff, Ralph S [Los Alamos National Laboratory; Shaw, Milton S [Los Alamos National Laboratory

    2010-01-01

    Plastic-bonded explosives are heterogeneous materials. Experimentally, shock initiation is sensitive to small amounts of porosity, due to the formation of hot spots (small localized regions of high temperature). This leads to the Ignition and Growth concept, introduced by Lee and Tarver in 1980, as the basis for reactive burn models. A homogeneized burn rate needs to account for three mesoscale physical effects (i) the density of burnt hot spots, which depends on the lead shock strength; (ii) the growth of the burn fronts triggered by hot spots, which depends on the local deflagration speed; (iii) a geometric factor that accounts for the overlap of deflagration wavelets from adjacent hot spots. These effects can be combined and the burn model defined by specifying the reaction progress variable {lambda}(t) as a function of a dimensionless reaction length {tau}{sub hs}(t)/{ell}{sub hs}, rather than by xpecifying an explicit burn rate. The length scale {ell}{sub hs} is the average distance between hot spots, which is proportional to [N{sub hs}(P{sub s})]{sup -1/3}, where N{sub hs} is the number density of hot spots activated by the lead shock. The reaction length {tau}{sub hs}(t) = {line_integral}{sub 0}{sup t} D(P(t'))dt' is the distance the burn front propagates from a single hot spot, where D is the deflagration speed and t is the time since the shock arrival. A key implementation issue is how to determine the lead shock strength in conjunction with a shock capturing scheme. They have developed a robust algorithm for this purpose based on the Hugoniot jump condition for the energy. The algorithm utilizes the time dependence of density, pressure and energy within each cell. The method is independent of the numerical dissipation used for shock capturing. It is local and can be used in one or more space dimensions. The burn model has a small number of parameters which can be calibrated to fit velocity gauge data from shock initiation experiments.

    Fatigue is a common consequence of numerous pediatric health conditions. In adult burn survivors, fatigue was found to be a major problem. The current cross-sectional study is aimed at determining the levels of perceived fatigue in pediatric burn survivors. Perceived fatigue was assessed in 23 children and adolescents (15 boys and 8 girls, aged 6-18 years, with burns covering 10-46% of the total body surface area, 1-5 years post burn) using both child self- and parent proxy reports of the Pediatric Quality of Life Inventory Multidimensional Fatigue Scale. Outcomes were compared with reference values of non-burned peers. At group level, pediatric burn survivors did not report significantly more symptoms of fatigue than their non-burned peers. Individual assessments showed, however, that four children experienced substantial symptoms of fatigue according to the child self-reports, compared to ten children according to the parent proxy reports. Furthermore, parents reported significantly more symptoms of fatigue than the children themselves. Age, gender, extent of burn, length of hospital stay, and number of surgeries could not predict the level of perceived fatigue post-burn. Our results suggest that fatigue is prevalent in at least part of the pediatric burn population after 1-5 years. However, the fact that parents reported significantly more symptoms of fatigue then the children themselves, hampers evident conclusions. It is essential for clinicians and therapists to consider both perspectives when evaluating pediatric fatigue after burn and to determine who needs special attention, the pediatric burn patient or its parent.

    As with most traumas, the epidemiology of the "burn" health-event has long been neglected by public health doctors and rarely considered by burns specialists. There were therefore few verified data and many approximations and preconceived ideas. The gathering of information recently undertaken in France enables the reliability of the data to be improved and the diagnostic and demographic elements relating to hospitalised patients with burns to be established.

    The objective of the study was to report the incidence of pediatric burn injuries and describe the pattern and the trend of pediatrics burns seen in King Abdul-Aziz Medical City. Retrospective cross-sectional study. Data collected through chart review of pediatrics patients aged 1-month to 14 years who presented with a burn injury to the pediatric emergency department during the year 2013. Burn patients were divided into two groups based on the percentage of total body surface area (TBSA) burned: Either Burn incidence rate was 4.9 patients/1000/year. Children with burns on more than 10% TBSA accounted for 16% incidence (0.8/1000 emergency department patients). The burn injury severity ranged from 1% TBSA to 37%, with a mean of 5%. The proportion of male and female burn patients was 54.1% and 45.9%, respectively. Children between 1 and 3 years of age sustained the majority (48.6%) of burn injuries. Scald burns were found to be the most common cause of injury. Hot water and beverages were considered root for most of the scald burn injuries. As children advance in age, scald injury becomes less likely, and they are more obviously subjected to flame burn injuries. Burn injuries sustained at home were 35% compared to 2.7% occurring outside the home. None of the study variables were good predictors for severe burn injuries affecting more than 10% TBSA. The incidence and the severity of burn injuries remain high at the national level. Burn injuries continue to affect the pediatric population, predominantly, young children, which indicate the need for increasing parent educational programs and government regulations. Because we reported scald burns as the most common causes of burn injury, which are consistent with previous national reports, we recommend having legislation that focuses on scald burn prevention.

    Turbulent burning velocities have been measured in an explosion bomb equipped with four high speed fans. Turbulent parameters were measured by laser doppler anemometry. The turbulent Reynolds numbers were significantly higher than in most previous measurements and high rates of strain were achieved until, ultimately, several of the flames quenched. Results are presented in terms of previously used dimensionless parameters plus a Lewis number and a dimensionless activation energy. The two-eddy theory of burning can allow for flame straining reductions in laminar burning velocity and experimental values of u_t/u_1 were compared with those from such a theory.

    Burns are ranked in the top 15 leading causes of the burden of disease globally, with an estimated 265,000 deaths annually and a significant morbidity from non-fatal burns, the majority located in low and middle-income countries. Given that previous estimates are based on hospital data, the purpose of this study was to explore the prevalence of burns at a population level in Nepal, a low income South Asian country. A cluster randomized, cross sectional countrywide survey was administered in Nepal using the Surgeons OverSeas Assessment of Surgical Need (SOSAS) from May 25th to June 12th, 2014. Fifteen of the 75 districts of Nepal were randomly chosen proportional to population. In each district, three clusters, two rural and one urban, were randomly selected. The SOSAS survey has two portions: the first collects demographic data about the household's access to healthcare and recent deaths in the household; the second is structured anatomically and designed around a representative spectrum of surgical conditions, including burns. In total, 1350 households were surveyed with 2695 individuals with a response rate of 97%. Fifty-five burns were present in 54 individuals (2.0%, 95% CI 1.5-2.6%), mean age 30.6. The largest proportion of burns was in the age group 25-54 (2.22%), with those aged 0-14 having the second largest proportion (2.08%). The upper extremity was the most common anatomic location affected with 36.4% of burns. Causes of burns included 60.4% due to hot liquid and/or hot objects, and 39.6% due to an open fire or explosion. Eleven individuals with a burn had an unmet surgical need (20%, 95% CI 10.43-32.97%). Barriers to care included facility/personnel not available (8), fear/no trust (1) and no money for healthcare (2). Burns in Nepal appear to be primarily a disease of adults due to scalds, rather than the previously held belief that burns occur mainly in children (0-14) and women and are due to open flames. This data suggest that the demographics and

    Many types of nosocomial infections (NIs) can be present in the burned patient. The purpose of this study is to calculate the rates for NI in the Intensive Care Unit of the Service of Burns and Plastic Surgery in University Hospital Centre (UHC) in Tirana, Albania. The study is prospective, clinical and analytical. The study is continued/longitudinal because monitors all patients with severe burns during a specified time period (1year). For data analysis was used SPSS 19.0. The infection prevalence rate was 12 infected patients per 100 patients. The colonisation prevalence rate was 43 colonised patients for 100 patients. The most frequent infection microorganisms were Pseudomonas aeruginosa and Staphylococcus aureus (67% and 24%). Incidence of BSI was 3 BSI for 1000 hospitalization days. Incidence of catheter-related bloodstream infection (CRBSI) was 11.7 BSI for 1000 catheter days. Colonisation of the tip of the central catheter (CTC) was 15.6 for 1000 catheter days. The epidemiology of burn wound infections as well as the definitions have changed due to important changes in burn wound treatment but further studies should be done documented the factors that can reduce the burn wound infection rates.

    Ignition and the burning of air-born single aluminum and magnesium particles are experimentally investigated. Particles of 30 to 106 μm-diameters were electrodynamically levitated, ignited, and burnt in atmospheric air. The particle combustion evolution was recorded by high-speed cinematography. Instant temperature and thermal radiation intensity were measured using two-wavelength pyrometry and photomultiplier tube methods. Ignition of the magnesium particle is prompt and substantially advances the aluminum particle by 10 ms. Burning time of the aluminum particles is extended 3 to 5 times longer than the magnesium particles. Exponents of a power-law fit of the burning rates are 1.55 and 1.24 for aluminum and magnesium particles, respectively. Flame temperature is slightly lower than the oxide melting temperature. For the aluminum, dimensionless flame diameter is inert to the initial particle size, but for the magnesium inversely proportional to the initial diameter.

    Full Text Available Introduction: One of the most important causes of mortality and morbidity in burn wards is infection, and it is the major reason of death in burn injuries. There are several reasons that make burn victims predisposed to infection. The current study aimed to investigate the role of different factors that have an effect on bacteremia occurrence in burn patients and factors which are relevant to mortality in these patients. Methods: This descriptive-analytic study conducted in a 1 year period in Sina Hospital, Tabriz University of Medical Sciences, Iran, and 81 burn were included. We collected patients’ data about their age, body weight, cause of burn, lesion color, place and percentage of burn by getting history and studying of their files. Then we documented all interventions. Blood tests and cultures and colonies criteria were recorded. Results: In this study, 39 patients were male (48.1%, and 42 was female (51.9%. Mean age was 32.06 ± 17.46 years. In patients without bacteremia, 57 patients did not need catheterization (89.1%, however in patients with bacteremia 9 patients demanded catheter insertion (52.9%. In patients with bacteremia 12 patients survived (70.9%, however in the without bacteremia group 56 patients survived (92.2%. Then, the relationship between type of burn, wound infection and bacterial species investigated, (P = 0.650, P = 0.210 and P = 0.110 respectively. Conclusion: We concluded, invasive interventions increased bacteremia susceptibility in our studied burned patients. Mortality rate is directly related to bacteremia prevalence and increased by extent of burn area in these patients. The three most frequent microbial agents responsible for bacteremia were Pseudomona aeruginosa, Klebsiella and Staphylococcus aureus.

    With the Arctic opening up to new shipping routes and increased oil exploration and production due to climate change, the risk of an Arctic oil spill is increasing. Of the classic oil spill response methods (mechanical recovery, dispersants and in-situ burning), in-situ burning is considered...... to be particularly a suitable response method in the Arctic. In-situ burning aims to remove the oil from the marine environment by burning it from the water surface. A recent Ph.D. thesis from the Technical University of Denmark has provided some new insights with respect to the fire science behind this response...

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

    The significance of burn types on hydrocarbon emissions from spark ignition engines was investigated by analyzing combustion signals with the utilization of spark plugs as ionization probes. A correlation between the simultaneously recorded combustion and cylinder pressure signals allowed for the use of combustion signals to identify three types of burns, viz., good burns, slow burns, and misfires. During both deceleration and operation with exhaust gas recirculation, degradation from good burns followed the same pattern irrespective of engine type tested. Good burns gradually turned into slow burns and then into misfires as deceleration became more severe or as the EGR rate was increased. Slow burns resulted in 3 to 13 times the hydrocarbons that resulted from good burns, and misfires increased hydrocarbon levels 18 to 24 times those resulting from good burns. About 60 percent of the unburned fuel leaving the engine cylinder appeared to be burned up in part of the exhaust manifold.

    To describe and further analyze the long-term results in visual acuity (VA), anatomical retention, and rate of complications from patients who underwent Boston keratoprosthesis (B-Kpro) type 1 after ocular chemical burns in the Dominican Republic. A retrospective review of 42 eyes (22 OD:20 OS) of 36 patients who underwent B-Kpro type 1 implantation after severe ocular burn at Hospital Elías Santana in Santo Domingo, Dominican Republic, between April 2006 and October 2014, were included. Demographics, VA, anatomical retention, and the rates of postoperative complications and concurrent surgeries were evaluated. The excellent anatomical retention rates and visual outcomes presented in this study support the remarkable capability of B-Kpro type 1 to restore functional VA in eyes with severe chemical injuries. However, strict control of the postoperative complications is necessary for long-term success. In conclusion, the use of a B-Kpro type 1 after severe chemical burn is a viable option in patients otherwise condemned to the high risk of failure associated with conventional corneal grafts.

    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

    To study the incidence and risk factors for citation and quotation errors in two major burns surgery journals. 120 references were randomly selected from original articles published in the following two journals - January to December 2006 issues of Burns and Journal of Burn Care & Research. For each reference, the ease of retrieval on PubMed and the presence of citation errors were noted. Two independent observers analysed each reference for quotation errors. The characteristics of the root article, that is, type of study, author numbers, number of references and article word count were noted. Of the 120 selected references, 117 referred to articles from indexed medical journals published in English. Among these, 4 articles could not be retrieved due to fatal citation errors (3.3%). A further 12 citation errors were noted giving a total citation error rate of 13.3% (95% CI: 6.74-19.93%). Of the 117 references analysed, the quotation error rate was 13.7% (95% CI: 8.6-19.5%) half of which were major errors. There was no significant association between the combined error rate per article and the journal (Kruskal-Wallis test; p=0.861, type of study (Kruskal-Wallis test; p=0.717), author numbers (Spearman's rho=0.197, p=0.423), article length (Spearman's rho=0.118, p=0.705) or references per article (Spearman's rho=0.229, p=0.189). Significant numbers of citation and quotation errors still appear in current burns literature. Incorrect spelling of author names and partial omissions of article titles were the two most common errors. No observable underlying factors were identified in this study. The present results serve as a reminder to authors, editors and peer reviewers for more care of citation accuracy when striving for their common goal of scientific excellence.

    Exposure to chemicals is an unusual causation of cutaneous burns in children. The aim of this study is to look at childhood chemical burns and compare this to adult chemical burns from the same population. A total of 2054 patients were referred to the pediatric burns unit during the study period. This included 24 cutaneous chemical burns, equating to an incidence of 1.1%. Over half of the injuries occurred in the domestic setting. The mean total body surface area (TBSA) affected was 1.9%. When compared to a cohort of adult patients from the same population with cutaneous chemical burns, the TBSA affected was identical (1.9%) but distribution favored the buttock and perineum in children, rather than the distal lower limb in adults. Children presented earlier, had lower rates of surgical intervention and had a shorter length of stay in hospital (p Chemical burns in children are rare, but are becoming more common in our region. It is important to be aware of the characteristic distribution, etiology and need to identify children at risk of child protection issues. Copyright © 2013 Elsevier Ltd and ISBI.

    The authors present a series of 6 deaths due to the uncommon cause of chemical burns. Of the 6 deaths due to chemical burns, 4 deaths were due to ingestion of a chemical, 1 death was caused by chemical burns of the skin, and 1 death resulted from rectal insufflation of a chemical. Seven additional cases where chemical burns may have been a contributing factor to the death or an incidental finding are also presented. Four cases are related to an incident involving chemical exposure during an industrial explosion. Three cases involve motor fuel burns of the skin. Two cases concern a plane crash incident, and 1 case involved a vehicular collision. Cases are derived from the records of the Dallas County Medical Examiner's Office and those of the authors' consultation practices. Each of the cases is presented, followed by a discussion of the various mechanisms of chemical injury.

    The purpose of this study was to determine the epidemiological factors of burns in pregnant women admitted to Motahari hospital in Tehran during a 7-year period. This retrospective descriptive study was carried out for a 7-year period. Researchers examined the medical records and documents of all 38 pregnant women admitted to Motahari hospital. The required data including age, days of hospitalization, burn percentage, cause of the burn, extent and severity of the burn, burn involved member, gestational age, and fetal and maternal outcomes were collected using check lists. The collected data were analyzed using statistical package using social sciences (SPSS) software version 20. During this 7-year period, 38 pregnant women with burns in different parts of their body were admitted to Motahari hospital in Tehran. Regarding burn frequency in the trimesters of pregnancy, the highest frequency was found in the second trimester (73.7%), and the frequency in the first and the third trimesters were 7.9 and 18.4%, respectively. Maternal mortality rate in the third trimester (57.1%) was higher than in the second (46.4%) and the first (33.3%) trimesters; however, fetal mortality rate was the highest in the first trimester (66.7%) followed by the third trimester (57.1%). Overall, fetal death occurred in half of the patients. The results of this study showed high maternal and fetal mortality rates in pregnant women with burns. This issue indicates that planning and implementing supportive and therapeutic protocols in these patients are of utmost importance and should be carried out by maintaining the health of mother and fetus immediately after patient hospitalization.

    Egro, Francesco M

    Burns teaching is organized only in a few medical schools in the United Kingdom. An e-learning tutorial was developed with the objective of incorporating burns teaching within the medical school curriculum. A 33-webpage e-learning was created, covering topics such as local and general response to burns, assessment of burns, first aid, primary and secondary survey, and referral guidelines. Medical student satisfaction was then evaluated using a 12-question feedback survey rated based on a Likert scale from 1 (very poor) to 5 (very good). The 12-question survey was completed by a total of 18 medical students ranging from second to fourth years (second = 17%, third = 22%, fourth = 61%). While only a couple of students had received prior burns teaching, 50% of the cohort had an interest to pursue surgery as a career. The majority of students (72%) would be interested to have an e-learning module on basic burns management in their medical curriculum. The means of all domains specific to the e-learning were rated as "good" or "very good." Students' rating for ease of use was 87%, usefulness was 88%, relevance to the medical curriculum was 90%, clarity and quality of content were 78% and 83%, respectively, design was 79%, and the overall satisfaction with this e-learning was 87%. The "Basic Burns Management" e-learning tutorial can provide an efficient and effective means of information delivery to medical students and junior doctors, allowing easy and fast incorporation of burns teaching within the medical curriculum and in other medical teaching settings.

    Many burn patients are needed to be referred to a tertiary burn hospital according to the American Burn Association (ABA) criteria. The purpose of this study was to verify the reasons for referring of the burn patients to the hospital. For 2 years, we prospectively surveyed the burn patients referred to a tertiary teaching burn hospital. Data for the following variables were collected and analyzed with SPSS software V21.0: causes of burn; age; gender; total body surface area (TBSA) measured at the referring center; TBSA measured at the receiving center; concomitant diseases and traumas; the reason for referral; condition of patients before and during the transportation; transportation time; presence of infection; presence of inhalation injury, electrical injury, and chemical injury; child abuse; insurance coverage; and results and outcomes of patients. A total of 578 burn patients (33.6% of the total admissions) were referred in the study period. Among these patients, 70.9% were females. The mean (SD) age of the patients was 35.3 (19.69) years. The mean (SD) of TBSA was 45.2 (26.3). Of the 578 patients, 45% were referred by request of the family or patients; 9% were referred because lack of diagnostic facility, approximately 43% were referred because of the need to be admitted in a tertiary burn center, 0.7% were referred because of a lack of capacity at other hospitals, and 0.5% were referred because of an error in the estimation of TBSA. A total of 45% of the referrals were by request of the family and patients. Tele-medicine may help to establish a direct contact between expert burn physicians and the patients and thus reduce unnecessary transfers. Approximately 9% of the referrals were because of lack of some diagnostic facilities. Copyright © 2016 Elsevier Ltd and ISBI. All rights reserved.

The clinical data of all children with burns younger than 14 years admitted between 1970 and 2008 were compared among different decades using Statistical Package for Social Sciences (SPSS). Of all patients with burns, children accounted for 28.6%, despite differences in different decades (18.7-31%). In all children with burns, greater than 80% were accounted by children with mild and moderate burns, and by scalds, in which greater than 80% was caused by hot water. The proportion of scald gradually increased from 60% in the 1970s to 88% in 21st century. The increase in the number in the infant group was the direct cause for the decline of the average age of children injured over time. The case fatality rate in all children with burns was 0.7%, despite significant differences in different decades. Current prevention strategies should be aimed at the 'susceptible group', namely infants, scald injuries and hot water scald, in particular, according to the epidemiologic characteristics of this study. Prevention methods from government, mass media and schools to the family is a tremendous need for the further development of prevention of paediatric burns in the future.

    Full Text Available Background: Loss of hand function has a detrimental impact on the physical and psychosocial functioning of those with hand burns. Of prime importance is the maintenance of range of movement (ROM. Subsequently, an ideal hand dressing needs to allow for full ROM, be comfortable, and facilitate healing. However, hand burns present complex challenges for burn clinicians with the dressing of choice remaining controversial. Patients and Methods: This retrospective review was undertaken to determine the effectiveness of the AQUACEL® Ag BURN glove as compared to silver sulfadiazine (SSD; standard care in patients with partial thickness hand burns. The average total body surface area % was 14.6% with an average age of 37 years. Eight hands were dressed with an AQUACEL® Ag BURN glove and eight were dressed with SSD. Results: Pain scores were reduced in those with the glove compared to those who were treated with SSD dressing. Mobility of the hand with the glove was reduced compared to the patients treated with SSD. The glove cost including outer dressings was $330 US, this is compared to $432 US for the SSD dressing based on the average reepithelization rate of 15 days, and translates into a financial saving of approximately $100 US per patient and further reduces workload and resources. Conclusion: The use of a hydrofiber silver impregnated glove for partial thickness hand burns, has clinical significance in the outpatient setting reducing the need for hospitalization, and the amount of dressing changes required.

    Educational theory highlights the importance of contextualized simulation for effective learning. We explored this concept in a burns scenario in a novel, low-cost, high-fidelity, portable, immersive simulation environment (referred to as distributed simulation). This contextualized simulation/distributed simulation combination was named "The Burns Suite" (TBS). A pediatric burn resuscitation scenario was selected after high trainee demand. It was designed on Advanced Trauma and Life Support and Emergency Management of Severe Burns principles and refined using expert opinion through cognitive task analysis. TBS contained "realism" props, briefed nurses, and a simulated patient. Novices and experts were recruited. Five-point Likert-type questionnaires were developed for face and content validity. Cronbach's α was calculated for scale reliability. Semistructured interviews captured responses for qualitative thematic analysis allowing for data triangulation. Twelve participants completed TBS scenario. Mean face and content validity ratings were high (4.6 and 4.5, respectively; range, 4-5). The internal consistency of questions was high. Qualitative data analysis revealed that participants felt 1) the experience was "real" and they were "able to behave as if in a real resuscitation environment," and 2) TBS "addressed what Advanced Trauma and Life Support and Emergency Management of Severe Burns didn't" (including the efficacy of incorporating nontechnical skills). TBS provides a novel, effective simulation tool to significantly advance the delivery of burns education. Recreating clinical challenge is crucial to optimize simulation training. This low-cost approach also has major implications for surgical education, particularly during increasing financial austerity. Alternative scenarios and/or procedures can be recreated within TBS, providing a diverse educational immersive simulation experience.

    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.

    Full Text Available A lepra constitui causa frequente de acometimento de nervos periféricos, em nosso meio. O sistema nervoso periférico é acometido por vezes sem que haja alterações cutâneas: é a chamada forma neurítica pura. Nessa variante, o nervo mais afetado é o ulnar. Nos casos de acometimento isolado de nervos periféricos somente a feitura de biópsia de nervo conduzirá ao diagnóstico. Assim, resolvemos realizar biópsia do ramo sensitivo superficial do nervo ulnar na mão em 17 pacientes com paresia ou paralisia desse nervo e espessamento do mesmo na altura do cotovelo. Os principais achados foram: redução do número de fibras mielínicas em 14 casos, infiltrado inflamatório em 13, fibrose em 12, desmielinização e remielinização em 9, presença de granuloma em 6 e visualização do Mycobacterium leprae em 5. Concluímos que a biópsia do ramo sensitivo superficial do nervo ulnar na mão é um bom meio diagnóstico de lepra em pacientes com acometimento desse nervo

    2013-09-01

    The aim of this study was to map out some epidemiological aspects of unintentional burn injuries among Iranian victims using a national injury registry data. Injury data were taken from a national injury surveillance system over the period 2000-2002. The study population comprised 31.5% of Iran's population. Burn-injury cases were retrieved and analysed. Of all the grossly 307,000 home injuries reported during the years 2000-2002 in Iran, about 125,000 cases (41%) were unintentional burn injuries. Women comprised 58% of the unintentional burn victims. The mean age among burn victims was 19.18±19 (standard deviation, SD) years. The age-adjusted incidence and mortality rates showed that children had a much higher incidence of domestic burns but the elderly suffered higher fatality in spite of lower incidence in this age group. Overall, 65.2% of the domestic burn injuries occurred in the living rooms or bedrooms followed by 27% in the kitchen. The hands and fingers were injured in 43.6% followed by the lower limbs in 37.6%. According to injury mechanism, scalds were the most common type of burn injuries comprising 77.7% of all burns. Of all the burn victims, 791 died, 48 victims became disabled and the remaining improved or were undergoing therapy when reported. Burns form a major health problem in Iran. Due to high mortality rate, the elderly need specific attention regarding burn prevention and treatment in this age group. Moreover, in spite of lower fatality, any prevention programme should have a focus on childhood burns mainly due to the overwhelming distribution of burns in children and the young population of Iran.

    Full Text Available Acute kidney injury (AKI is a common complication in patients with severe burn injury and one of the major causes of death. It has a negative prognostic value and almost always develops in the context of multiple organ dysfunction syndrome (MODS induced by sepsis. Over the last 20 years, according to data avaliable, the mortality rate has been reported to reach about 75%. Several definitions of AKI have been used , but nowadays the RIFLE classification is considered the gold standard, enabling a more objective comparison of populations. There are several ways to treat AKI in burn patients, including peritoneal dialysis (PD, intermittent hemodialysis, and continuous renal replacement therapy (CRRT. CRRT is generally used in patients in whom intermittent hemodialysis has failed to control hypovolemia, as well as in patients who cannot tolerate intermittent hemodialysis. Additionally, PD is not suitable for patients with burns within the abdominal area. For these reasons, most patients with unstable hemodynamic conditions receive CRRT. In burn patients with acute renal failure the dialytic treatment with continuous renal replacement therapies permitted us to achieve a survival and dialytic adequacy; however, mortality rate is high and related to septic shock and MODS. Despite the wide variation of the analysed burn populations and definitions of AKI, this review clearly showed that AKI remains prevalent and is associated with increased mortality in patients with severe burn injury.

    The leading etiologies of pediatric burns are scald, thermal, and electrical injuries. The initial management of burns involves assessment of burn depth and total body surface area (TBSA) affected, a history, and physical examination. Calculation of percent of TBSA affected is an important determinant of the necessity for hospitalization versus outpatient management. Only second- and third-degree burns are included in the calculation. The criteria for outpatient management vary based on the center experience and resources. One such set of criteria in an experienced burn center includes burn affecting less than 15% TBSA, therefore not requiring fluid resuscitation; the ability to take in oral fluids, excluding serious perioral burns; no airway involvement or aspiration of hot liquid; no abuse; and dependable family able to transport the patient for clinic appointments. Once the child is ready to reenter school, the physician must discuss with the family and school staff any needs and expectations for the child, including wound care. Social reintegration can be difficult. Educating the teachers and staff of the child's appearance may help prepare the students.

  3. Rehabilitation of the burn patient

    2010-10-01

    Full Text Available Rehabilitation is an essential and integral part of burn treatment. It is not something which takes place following healing of skin grafts or discharge from hospital; instead it is a process that starts from day one of admission and continues for months and sometimes years after the initial event. Burns rehabilitation is not something which is completed by one or two individuals but should be a team approach, incorporating the patient and when appropriate, their family. The term ′Burns Rehabilitation′ incorporates the physical, psychological and social aspects of care and it is common for burn patients to experience difficulties in one or all of these areas following a burn injury. Burns can leave a patient with severely debilitating and deforming contractures, which can lead to significant disability when left untreated. The aims of burn rehabilitation are to minimise the adverse effects caused by the injury in terms of maintaining range of movement, minimising contracture development and impact of scarring, maximising functional ability, maximising psychological wellbeing, maximising social integration

    Full Text Available Burn injury is one of the most serious injuries that mankind may face. In addition to serious inflammation, excessive fluid loss, presence of hemodynamic instability due to intercurrent factors such as debridements, infections and organ failure, very different levels and intensities of pain, psychological problems such as traumatic stress disorder, depression, delirium at different levels that occur in patient with severe burn are the factors which make it difficult to provide the patient comfort. In addition to a mild to moderate level of baseline permanent pain in burn patients, which is due to tissue damage, there is procedural pain as well, which occurs by treatments such as grafting and dressings, that are severe, short-term burst style 'breakthrough' pain. Movement and tactile stimuli are also seen in burn injury as an effect to sensitize the peripheral and central nervous system. Even though many burn centers have established protocols to struggle with the pain, studies show that pain relief still inadequate in burn patients. Therefore, the treatment of burn pain and the prevention of possible emergence of future psychiatric problems suc as post-traumatic stress disorder, the sedative and anxiolytic agents should be used as a recommendation according to the needs and hemodynamic status of individual patient.

    Discovery of fire at the dawn of prehistoric time brought not only the benefits to human beings offering the light and heat, but also misfortune due to burns; and that was the beginning of burns treatment. Egyptian doctors made medicines from plants, animal products and minerals, which they combined with magic and religious procedures. The earliest records described burns dressings with milk from mothers of male babies. Goddess Isis was called upon to help. Some remedies and procedures proved so successful that their application continued for centuries. The Edwin Smith papyrus (1500 BC) mentioned the treatment of burns with honey and grease. Ebers Papyrus (1500 BC) contains descriptions of application of mud, excrement, oil and plant extracts. They also used honey, Aloe and tannic acid to heal burns. Ancient Egyptians did not know about microorganisms but they knew that honey, moldy bread and copper salts could prevent infections from dirt in burns healing. Thyme, opium and belladona were used for pain relief. In the 4th century BC, Hippocrates recorded that Greek and Roman doctors used rendered pig fat, resin and bitumen to treat burns. Mixture of honey and bran, or lotion of wine and myrrh were used by Celsus. Honey was also known in Ayurveda (Indian medicine) time. Ayurvedic records Characa and Sushruta included honey in their dressing aids to purify sores and promote the healing. Burn treatment in Chinese medicine was traditional. It was a compilation of philosophy, knowledge and herbal medicine. The successful treatment of burns started in recent time and it has been made possible by better knowledge of the pathophysiology of thermal injuries and their consequences, medical technology advances and improved surgical techniques.

  6. Colloids in Acute Burn Resuscitation.

    Colloids have been used in varying capacities throughout the history of formula-based burn resuscitation. There is sound experimental evidence that demonstrates colloids' ability to improve intravascular colloid osmotic pressure, expand intravascular volume, reduce resuscitation requirements, and limit edema in unburned tissue following a major burn. Fresh frozen plasma appears to be a useful and effective immediate burn resuscitation fluid but its benefits must be weighed against its costs, and risks of viral transmission and acute lung injury. Albumin, in contrast, is less expensive and safer and has demonstrated ability to reduce resuscitation requirements and possibly limit edema-related morbidity. Copyright © 2016 Elsevier Inc.

    .1 days (range 1-333 days). Surgery was performed in 146 patients (21.16%), and the overall mortality rate was 0.58%. Chemical burns are preventable. The high morbidity of chemical burns in western Zhejiang Province is related to the industrial structure of the area. Governmental management in the fields of production, transportation, and utilization of chemicals could be improved. Workplaces have the responsibility to provide safe work environments and equipment, as well as occupational education and safety training for high-risk work groups.

    Full Text Available OBJECTIVE: The aim of the study was to analyze a series of Brazilian patients suffering from MELAS. METHOD: Ten patients with MELAS were studied with correlation between clinical findings, laboratorial data, electrophysiology, histochemical and molecular features. RESULTS: Blood lactate was increased in eight patients. Brain image studies revealed a stroke-like pattern in all patients. Muscle biopsy showed ralled-red fibers (RRF in 90% of patients on modified Gomori-trichrome and in 100% on succinate dehydrogenase stains. Cytochrome c oxidase stain analysis indicated deficient activity in one patient and subsarcolemmal accumulation in seven patients. Strongly succinate dehydrogenase-reactive blood vessels (SSV occurred in six patients. The molecular analysis of tRNA Leu(UUR gene by PCR/RLFP and direct sequencing showed the A3243G mutation on mtDNA in 4 patients. CONCLUSION: The muscle biopsy often confirmed the MELAS diagnosis by presence of RRF and SSV. Molecular analysis of tRNA Leu(UUR gene should not be the only diagnostic criteria for MELAS.OBJETIVO: O objetivo deste estudo foi analisar uma série de pacientes brasileiros portadores de MELAS.

    Burns in the neonate are rare and result mostly from iatrogenic sources in developed countries. The socioeconomic settings of developing countries are different from those in the developed countries. A review of the epidemiology and management of burns in the neonates in Lagos, Nigeria is presented. The case notes of burns in patients less than 29 days-old from 2004 to 2008 in 4 tertiary health institutions in Lagos were retrieved from the Medical Records Department; necessary data were extracted and analyzed. There were 21 neonates with burns within the study period. The incidence of neonatal burns ranged between 0.5 and 2.5%/year. The mean age was 16.38 ± 1.84 days and the mean BSA of 26.00 ± 5.53%. The etiology of burns was thermal in 19(90.5%) and chemical in 2(9.5%). Hypokalemia was common at early stages of their treatment. Burns were sustained at home in 90.5% of the cases. The mortality rate was 43.5%. Inhalation and thermal injuries were associated with most of the deaths. Domestic incidents from flames are the commonest causes of neonatal burns in the study environment. These are associated with prolonged morbidity and high mortality rate. Health education, highlighting methods of prevention should be undertaken in the community. Well equipped burn centers should be established to treat burns in all age groups.

    2002-01-01

    Wildlife managers in the Gulf Coast Chenier Plain of Louisiana and Texas frequently burn marshes during winter to improve habitat for wintering waterfowl and furbearers. Such fires dramatically alter vegetation structure and cover, although such changes are generally temporary. However, if vegetation cover does not recover sufficiently by the start of the subsequent breeding season, nests of marsh birds could be exposed to increased predation rates. We examined effects of burning on 2 measures of vegetation structure and on 2 types of artificial bird nests during breeding seasons (May and June) before and after experimental winter burns (December and January). We found that vegetation structure did not differ between burned and non-burned marshes at 5 months post-burn. Similarly, depredation rates of artificial sparrow and duck nests did not differ between burned and non-burned marshes during the post-burn breeding season. We recommend that managers complete burning programs by the end of January so that sufficient nesting cover develops before the start of the breeding season.

    2011-01-01

    An experimental test series, comprising 10 experiments with varying pool sizes, lining materials and amounts of liquid burning, was conducted under free burn and room burn conditions. The thermal feedback from the enclosure (ISO 9705 Room Corner Test facility) enhanced the burning rate of the pools...... and resulted in a thermal runaway in some of the runs. The onset of the thermal runaway, which can be associated with flashover, varied with all the input parameters. The lining with the lowest thermal inertia lead to the fastest increase in the heat release rate (HRR) in the enclosure and caused flashover...... in the shortest time. Given the profound difference between the enclosure tests and the free burn tests and also between enclosure tests with different linings, it is recommended to show great caution if free burn tests are to be used in design fire scenarios....

    Thermodynamic property research is justly recognized as invaluable by process and design engineers in the petroleum, chemical, and allied industries. Thermodynamic data for pure fluids or complex mixtures are essential in the optimum design of both physical and chemical processing units. Coal-derived liquids are a new and vital class of industrial compounds for which there are limited thermodynamic data. Programs have been undertaken to measure volumetric properties and K values of light gas-model compound systems and to measure dew points, vapor pressures, and hydrogen solubilities in model compound and coal-derived liquid systems. The objective of the present study is to measure equilibrium K values of coal-derived liquids and model compounds representative of coal liquids, and to use the results in the development of engineering correlations. The program is divided into three major areas: design, construction, and evaluation of an equilibrium flash vaporization system for temperatures between 70 and 700/sup 0/F and pressures up to 2000 psia; measurements on samples of both coal-derived liquids and mixtures of model compounds; and preparation of engineering correlations for the measured K values and vapor liquid equilibria. Due to continued leaks of potentially harmful cresol and quinoline in the flash-vaporization cell it became necessary for us to shut down the equipment for reasons of safety. Efforts to seal the original cell over the large temperature cycles required proved ineffective. Thus, the major effort during the past six months was the design, construction, and development of a new equilibrium cell that would maintain the seal between the cell and the sight window over many temperature cycles. The final design which accomplishes this objective uses a custom-fabricated sapphire window with custom gold o-rings used for the seals. Due to the unanticipated equipment development, the data-collection effort has been delayed.

  16. Honey dressing in pediatric burns

    Full Text Available The medicinal properties of honey have been recognized since antiquity. Although used as an adjuvant method of accelerating wound healing from ancient times, honey has been sporadically used in the treatment of burns. Honey acts mainly as a hyperosmolar medium and prevents bacterial growth. Because of its high viscosity, it forms a physical barrier, and the presence of enzyme catalase gives honey an antioxidant property. Its high-nutrient content improves substrate supply in local environment promoting epithelialization and angiogenesis. In pediatric burn patients no exclusive study has been conducted using honey as a burn dressing. An attempt is being made to evaluate the effect of honey in the management of burns in pediatric patients.

    Full Text Available Cigarette-burning and the smoke-formation processes and smoke composition are important topics for understanding cigarette performance. This paper proposes the molecular formulas representing the active components of bright, burley, and Oriental tobaccos and a basic chemistry model of the cigarette burning processes. Previous knowledge of the cigarette burning processes and smoke formation helped to establish parameters in deriving the basic chemistry equations. The proposed chemistry provides a brief view of the mechanisms of the cigarette burning during puffing and interpuff smoldering, and can be used to interpret and predict the smoke composition for cigarettes made from bright, burley, and Oriental tobaccos. Based on the proposed chemistry, the effect of ventilation on smoke component deliveries is discussed and the reaction heat of the puffing process is estimated.

    This report describes the epidemiology of burn injuries and quantifies the appropriateness of use of available interventions at Kamuzu Central Hospital, Malawi, between July 2008 and June 2009 (370 burn patients). Burns accounted for 4.4% of all injuries and 25.9% of all burns presenting to the hospital were admitted. Most patients (67.6%) were Burns occurred most frequently in the cool, dry season and in the evening. The mean burn surface area (second/third degree) was 14.1% and most burns (74%) presented within 8 h. The commonest procedure was debridement and/or amputation. The mean hospital stay was 21.1 days, in-hospital mortality was 27% and wound infection rate was 31%. Available interventions (intravenous fluids, nutrition therapy, physiotherapy) were misapplied in 59% of cases. It is concluded that primary prevention should address paediatric and scald burns, and secondary prevention should train providers to use available interventions appropriately.

    Full Text Available Aim: To study the epidemiological data of paediatric burn patients to determine the role of demographic distribution and epidemiological parameters for assessment of mortality rate and development of burn prevention strategy. Materials and Methods : Epidemiological data of 500 patients admitted to the Burns and Plastic Surgery Unit of B.J. Wadia Hospital, Mumbai over a period of six years (2000-2005 was reviewed from medical records. Age, sex, demographic distribution, seasonal variation, total body surface area (TBSA involved, type and place of burn injury, parental occupation, family size, first aid and mortality rate were studied. Result: Median age group for patient was 3.44 years (range one month to 14 years. The majority (24% of burns occurred in children between the one to two years age group. Male to female sex ratio was 1.38:1. Most of the patients were from the defined demographic region served by the hospital. A significant number of patients however were from outside this region. Burn injury occurred predominantly during winter. Most common type of burn was scalds which occurred mainly in domestic circumstances. In the majority of patients, less than 10% TBSA was involved. All patients were managed as per the unit protocol. Mortality rate was 10.4%. Mortality rate was high in patients having more than 40% TBSA involvement. Seventy-three per cent of the total deaths occurred in the patients coming from regions outside the demographic region served by the hospital. Parental occupation, family size and the first aid did not affect the mortality rate. Conclusion: Availability of a burn care unit in the vicinity can decrease the mortality rates in the paediatric burn patients. An intense and focused burn prevention campaign to educate the general population about dangerous aetiological factors will decrease the incidence of paediatric burns.

    While it is globally observed that young children are at a higher risk of burn injuries, little is known about childhood burns in Iraqi Kurdistan. This study was undertaken to describe the epidemiology of burns amongst pre-school children in this region. A prospective study was undertaken from November 2007 to November 2008 involving all children aged 0-5 years attending the burns centre in Sulaimaniyah province for a new burn injury whether treated as an outpatient or admitted to hospital. 1,122 children attended the burns centre of whom 944 (84%) were interviewed (male 53%, female 47%). Mean age was 1.9 years with children aged 1 year comprising 32% and those aged 2 years comprising 21% of the sample. The incidence of burns was 1044/100,000 person-years (1030 in females and 1057 in males). Mechanisms of injury included scalds (80%), contact burns (12%) flames (6%) and other mechanisms (2%). Almost 97% of burns occurred at home including 43% in the kitchen. Winter was the commonest season (36%) followed by autumn (24%). There were 3 peak times of injury during the day corresponding to meal times. The majority of burns were caused by hot water (44%) and tea (20%) and the most common equipment/products responsible were tea utensils (41%). There were 237 admissions with an admission rate of 95 per 100,000 person-years. Scald injuries accounted for most admissions (84%). Median total body surface area affected by the burn or scald (TBSA) was 11% and median hospital stay was 7 days. In-hospital mortality was 8%. Mortality rate was 4% when TBSA was ≤25%, and 100% when TBSA was over 50%. Burn incidence is high in young children especially those aged 1-2 years. Preventive interventions targeted at families with young children & focusing on home safety measures could be effective in reducing childhood burns. Copyright © 2014 Elsevier Ltd and ISBI.

    To determine and compare outcomes with accepted benchmarks in burn care at 6 academic burn centers. Since the 1960s, US morbidity and mortality rates have declined tremendously for burn patients, likely related to improvements in surgical and critical care treatment. We describe the baseline patient characteristics and well-defined outcomes for major burn injuries. We followed 300 adults and 241 children from 2003 to 2009 through hospitalization, using standard operating procedures developed at study onset. We created an extensive database on patient and injury characteristics, anatomic and physiological derangement, clinical treatment, and outcomes. These data were compared with existing benchmarks in burn care. Study patients were critically injured, as demonstrated by mean % total body surface area (TBSA) (41.2 ± 18.3 for adults and 57.8 ± 18.2 for children) and presence of inhalation injury in 38% of the adults and 54.8% of the children. Mortality in adults was 14.1% for those younger than 55 years and 38.5% for those aged 55 years and older. Mortality in patients younger than 17 years was 7.9%. Overall, the multiple organ failure rate was 27%. When controlling for age and % TBSA, presence of inhalation injury continues to be significant. This study provides the current benchmark for major burn patients. Mortality rates, notwithstanding significant % TBSA and presence of inhalation injury, have significantly declined compared with previous benchmarks. Modern day surgical and medically intensive management has markedly improved to the point where we can expect patients younger than 55 years with severe burn injuries and inhalation injury to survive these devastating conditions.

  6. DIFFERENTIATING PERIMORTEM AND POSTMORTEM BURNING

    Directory of Open Access Journals (Sweden)

    2015-01-01

    Full Text Available One of the most challenging cases in forensic medicine is ascertaining the cause of death of burnt bodies under suspicious circumstances. The key questions that arise at the time of investigation include: 1  Was the person alive or dead prior to fire accident?  Did the victim die because of burn?  If death was not related to burns, could burns play a role in causing death?  Were the burns sustained accidentally, did the person commit suicide or was the person murdered?  Are the circumstances suggesting an attempt to conceal crime?  How was the fire started?  How was the victim identified?  In case of mass fatalities, who died first? Postmortem burning of corpses is supposed to be one of the ways to hide a crime. Differentiating the actual cause of death in burn patients is therefore important. Medical examiners usually focus on the defining the changes that occur in tissues while forensic anthropologists deal with the changes related to the bone with or without any the influence of other tissues. Under the circumstances of fire, differentiating the perimortem trauma from that of postmortem cause of bone fractures is vital in determining the cause and motive of death

  7. Chemical and Common Burns in Children.

    Burns are a common cause of preventable morbidity and mortality in children. Thermal and chemical burns are the most common types of burns. Their clinical appearance can be similar and the treatment is largely similar. Thermal burns in children occur primarily after exposure to a hot surface or liquid, or contact with fire. Burns are typically classified based on the depth and total body surface area, and the severity and onset of the burn can also depend on the temperature and duration of contact. Chemical burns are caused by chemicals-most commonly acids and alkalis-that can damage the skin on contact. In children, the most common cause of chemical burns is from household products such as toilet bowl cleaners, drain cleaners, detergents, and bleaches. Mild chemical burns generally cause redness and pain and can look similar to other common rashes or skin infections, whereas severe chemical burns are more extreme and may cause redness, blistering, skin peeling, and swelling.

    Dr. Basil A. Pruitt Jr., a consummate clinical and translational surgeon-scientist, has been spent over half a century at the forefront of an advancing standard of burn care. Commanding the US Army Institute for Surgical Research in San Antonio, he trained generations of leading burn clinicians and allied scientists. At his direction, there were forged discoveries in resuscitation from shock, treatment of inhalation injury, control of burn-related infections, prevention of iatrogenic complications, and understanding the sympathetic, endocrine, and immune responses to burn injury. Most consequentially, this team was among the first recognize and define alterations in the basal metabolic rate and thermoregulation consequent to burn injury. These investigations prompted groundbreaking insights into the coordinated nervous, autonomic, endocrine, immune, and metabolic outflows that a severely-burned patient uses to remain alive and restore homeostasis. Marking his scientific consequence, many of his reports continue bear fruit when viewed through a contemporary lens. This paper summarizes some of the major findings of his career thus far, and is intended to complement a Festschrift recently held in his honor. Not applicable.

    Full Text Available To identify the characteristics of completed suicide by burning in Tehran. A retrospective analysis of data obtained from Tehran's Legal Medicine Organization and judiciary system over 5-years (from 2002 to 2006. During the 5 years, 374 decedents (64.2% female and 35.8% male were diagnosed as suicide by self-burning, and the annual incidence rate was 0.9 per 100,000 general population-years. The most at risk group was young females. Sixty-five decedents (17.4% had died at the scene of incidents. The location at the time of attempted suicide in all female victims and 75.4% of male decedents was home. Sixty-one percent of decedents were married and 26.2% of them had no education. Most victims were residents of suburban areas. The annual incidence rate of self-burning suicide in Tehran was found to be lower than other Iran's geographic areas, although it was higher than developed countries. Self-burning was more frequent in females than in males and was noted mainly in young age groups' residents of suburban areas with low level of education. These characteristics suggest that social factors are the main drive leading to an unacceptably high rate of suicide by self-burning among women in Tehran.

    Controlled 'patch' burning of moorland vegetation has been used for decades in the UK to stimulate growth of heather (Calluna vulgaris) for game bird habitat and livestock grazing. Typically small patches (300-900 m2) are burned in rotations of 8-25 years. However, our understanding of the short-to-medium term environmental impacts of the practice on these sensitive upland areas has so far been limited by a lack of scientific data. In particular the effect of burning on concentrations of base cations and acid-base status of these highly organic soils has implications both for ecosystem nutrient status and for buffering of acidic waters. As part of the EMBER project peat chemistry data were collected in ten upland blanket peat catchments in the UK. Five catchments were subject to a history of prescribed rotational patch burning. The other five catchments acted as controls which were not subject to burning, nor confounded by other detrimental activities such as drainage or forestry. Soil solution chemistry was also monitored at two intensively studied sites (one regularly burned and one control). Fifty-centimetre soil cores, sectioned into 5-cm intervals, were collected from triplicate patches of four burn ages at each burned site, and from twelve locations at similar hillslope positions at each control site. At the two intensively monitored sites, soil solution chemistry was monitored at four depths in each patch. Across all sites, burned plots had significantly smaller cation exchange capacities, lower concentrations of exchangeable base cations and increased concentrations of exchangeable H+ and Al3+ in near-surface soil. C/N ratios were also lower in burned compared to unburned surface soils. There was no consistent trend between burn age and peat chemistry across all burned sites, possibly reflecting local controls on post-burn recovery rates or external influences on burn management decisions. At the intensively monitored site, plots burned less than two years

    Blood is a vital resource commonly used in burn patients; however, description of blood transfusions in severe burns is limited. The purpose of this study was to describe the epidemiology of blood transfusions and determine factors associated with increased transfusion quantity. This is a retrospective study of total 133 patients with >40% total body surface area (TBSA) burns admitted to the burn center of Changhai hospital from January 2008 to December 2013. The study characterized blood transfusions in severe burn patients. Univariate and Multivariate regression analyses were used to evaluate the association of clinical variables with blood transfusions. The overall transfusion rate was 97.7% (130 of 133). The median amount of total blood (RBC and plasma), RBC and plasma transfusions was 54 units (Interquartile range (IQR), 20-84), 19 units (IQR, 4-37.8) and 28.5 units (IQR, 14.8-51.8), respectively. The number of RBC transfusion in and outside operation room was 7 (0, 14) and 11 (2, 20) units, and the number of plasma was 6 (0.5, 12) and 21 (11.5, 39.3) units. A median of one unit of blood was transfused per TBSA and an average of 4 units per operation was given in the series. The consumption of plasma is higher than that of RBC. On multivariate regression analysis, age, full-thickness TBSA and number of operations were significant independent predictors associated with the number of RBC transfusion, and coagulopathy and ICU length showed a trend toward RBC consumption. Predictors for increased plasma transfusion were female, high full-thickness TBSA burn and more operations. Severe burn patients received an ample volume of blood transfusions. Fully understanding of predictors of blood transfusions will allow physicians to better optimize burn patients during hospitalization in an effort to use blood appropriately.

    Diphoterine is a hypertonic, amphoteric, polyvalent and chelating decontamination solution used in the treatment of cutaneous and ocular chemical burns. Due to infrequent use by emergency physicians along with the small number of available studies, its debate in the literature as to its efficacy and safety remains inconclusive. A structured literature search was performed in MEDLINE, EMBASE BIOLOGICAL ABSTRACTS and TOXNET to June 2016 for original English-language studies reporting on the safety and effectiveness of Diphoterine. Methodological and reporting quality of pre-clinical animal studies was assessed using the Systematic Review Centre for Laboratory Animal Experimentation (SYRCLE) risk of bias tool and Animal Research: Reporting of In Vivo Experiments (ARRIVE) guidelines. Clinical studies were assessed using Chambers' criteria. 13 studies (seven in the pre-clinical, five in the clinical setting and one mixed) met the study inclusion criteria. Pre-clinical studies showed a faster resolution of pH and reduced tissue necrosis with Diphoterine. Clinical studies showed reduced tissue necrosis/severity of symptoms, faster pH resolution and a reduction in pain when using Diphoterine. No adverse events were attributable to Diphoterine. Reporting and methodology of the studies was poor or showed a high risk of bias. Diphoterine appears to be safe to use and is probably superior to other rinsing solutions. However, immediate decontamination is imperative and if Diphoterine is not available a different rinsing solution should be used. The methodology of the published literature for Diphoterine is generally poor and future publications should use the frameworks given as templates. Crown Copyright © 2017. Published by Elsevier Ltd.

    Carrougher, Gretchen J; Brych, Sabina B; Pham, Tam N; Mandell, Samuel P; Gibran, Nicole S

    Rates of return to work (RTW) after burn injury vary. A 2012 systematic review of the burn literature reported that nearly 28% of all adult burn survivors never return to any form of employment. These authors called for interventions designed to assist survivors' ability to function in an employed capacity. In 2010, our burn center outpatient clinic instituted an intervention aimed to return injured workers to employment within 90 days of their insurance claims. The interventions include patient/family education focused on recovery rather than disability, employer contact and education by the vocational rehabilitation (VR) counselor, physician recommendations for work accommodations, provision of employee status letters, and Activity Prescription Forms (APFs). The purpose of this study is to report on the effectiveness of these interventions. Following institutional review board (IRB) approval, medical records of adults with occupation-related burn injuries and receiving care at a single regional burn center from June 2010 to July 2015 were reviewed. Data on patient and injury characteristics and outpatient VR services provided were collected. The primary outcome of interest was the percentage of patients who RTW; 338 individuals met study entry criteria. The VR counselor evaluated all patients. All patients received an employer letter(s) and APF documentation. Workplace accommodations were provided to more than 30% of patients. RTW rate was 93%, with an average of 24 days from injury to RTW. In an intervention bundle involving the patient, employer, Workers' compensation, and the burn clinic staff, injured workers achieved a high rate of RTW. Although we cannot correlate individual bundle components to outcome, we postulate that the combination of employer/employee/insurer engagement and flexibility contributed to the success of this program.

    Nebulised heparin, N-acetylcysteine (NAC) and salbutamol were shown to decrease reintubation rates, incidence of atelectasis and mortality in paediatric patients and reduce lung injury scores in adult burns patients with inhalational lung injury (ILI). Nebulised heparin, NAC and salbutamol treatment protocol was introduced in Singapore General Hospital (SGH) Burns Centre in 2006. However, safety data on the use of nebulised heparin and NAC for burns patients with ILI is not well established. In this study, we investigated the safety and potential anticoagulant effects of nebulised heparin in burns patients with ILI. A retrospective study with historical control was conducted. The treatment group consisted of 52 mechanically ventilated adult patients, with a diagnosis of ILI as confirmed by bronchoscopy, admitted to burn intensive care unit (BICU) from the year 2006 to 2009. The group was treated with nebulised heparin, NAC and salbutamol. The control group consists of 11 mechanically ventilated BICU ILI patients treated from year 2001 to 2005 before protocol initiation. Blood coagulation indices (prothrombin time (PT), activated partial thromboplastin time (APTT) and platelet count) were monitored and bleeding incidences were assessed. Blood coagulation indices did not suggest an increase risk of bleeding with nebulised heparin. The APTT, PT and platelet count followed a similar trend for both groups over 7 days. No clinically significant increase in bleeding risk was found to be associated with nebulised heparin. Nebulised heparin was not found to potentiate the risk of bleeding in burns patients with ILI.

    Young children are the most vulnerable for sustaining burns. At this pediatric burn hospital we have provided medical care to young children with severe burns from Mexico for many years. This study identified modifiable risk factors that could be used to assist in prevention of burns in this age group. A retrospective chart review was performed with children burns >20% total body surface area (TBSA) burned. Primary causes of burns were flame and scalds. Children with flame injuries were older (3.0±1.5 years of age) than those with scalds (2.6±1.2 years of age). Admissions attributed to flame burns were largely from explosions by propane tanks, gas line leaks, and house fires. Most admissions for scalds were predominantly from falling in large containers of hot water, food, or grease; and fewer were attributed to spills from hot liquids. Most cases reported to a social service agency were to find resources for families. Mortality rate for flame and scald burns was low. It is important take into account demographic, cultural, and socioeconomic variables when developing and implementing prevention programs. Burn prevention instruction for parents is crucial.

    Insecticide-treated bed nets are essential tools to prevent malaria in endemic regions, however, increasing trends in bed net related burns in Kampala, Uganda are concerning. Data were collected from burns unit admission records at Mulago National Referral Hospital in Kampala, Uganda for the years 2008-2011 inclusive. Retrospective analyses on the characteristics of patients admitted with bed net related burns within this period were conducted. A total of 45 patients were admitted to the burns unit with bed net related burns during the study period. Most burns occurred among individuals who were 0-1 years old (33.3%) and 26-35 years old (24.2%) and the majority were male (71%). Bed net related burns at Mulago Hospital are severe, as evidenced by the fact that 15 of 45 patients died (crude mortality rate=33%) and that 26 patients (57.8%) had total body surface area burn percentages that were greater than 20%. The average length of stay in hospital for patients with bed net related burns was 30.4 days. Organizations responsible for malaria prevention should consider incorporating fire and burn prevention awareness, strategies and training into their bed net distribution programs.

    To determine epidemiological trends among burns patients admitted to our burns center during 2003-2012, and the usefulness of the Abbreviated Burns Severity Index (ABSI) for predicting burns-related mortality. We retrospectively reviewed the data of 4481 burns patients. We analyzed the epidemiological trends and ABSI scores using Student t-test and one-way analysis of variance (continuous variables), chi-square test (categorical variables) and stepwise logistic-regression analysis (predictors of mortality). The mean age and male-to-female ratio were 39.9±19.7 years and 2.88, respectively. ABSI scores decreased from 7.7±3.0 in 2003 to 6.9±3.0 in 2012. Mortality rate improved from 24.5% in 2003 to 15.8% in 2012. Burns were caused by flames (67.3%), scalding (22.0%) and electrical (7.5%), chemical (1.6%) and contact (1.5%) injuries. Scalding and flames were the most common causes in patients aged ≤20 years and ≥21 years, respectively. Female sex, inhalation injury, full-thickness burns, large total body surface area (TBSA) burned and old age predicted mortality. ABSI scores 14 were associated with 0.7% and >90% mortality, respectively. The mortality of major burns has decreased but remains high. ABSI scores predict burns-related mortality.

    Burns in children are a major public health problem with long-lasting physical and psychological sequelae. Previous studies have identified that children from ethnic minorities have higher rates of burns. The purpose of this study was to analyse the differences in paediatric burn mechanism and severity within different ethnic groups. Demographic and burn data from all paediatric patients presenting with burn at the Burns Service, Alder Hey Children's NHS Foundation Trust, Liverpool, UK were collected over a 5 year period. 766 paediatric patients (age range: 7 days to 16 years old, mean: 4.5 years) were included in the study. Ethnic minority children had higher total body surface area of burn (pethnic minority children. Chinese children had most burns from hot food (60%), whereas non-ethnic minority children had most burns from hot beverages (35.8%). Ethnic minority children were more deprived compared with non-ethnic minority children (Index of Multiple Deprivation 48.7 vs. 40.9; p=0.02). These results show that there are significant differences in the patterns of burns in ethnic minority groups. This data should guide targeted public health prevention and educational strategies.

    Full Text Available AIM: Burn is a kind of painful trauma that requires a long period of treatment and also changes patients body image. For this reason, nursing care of burn patients is very important. In this study in order to provide qualified care to the burned patients, patient and #8217;s expectations from nurses were aimed to be established. METHODS: Patients and #8217; expectations were evaluated on 101 patients with burn in Ministry of Health Ankara Numune Education and Research Hospital Burn Service and Gulhane Military Medical Academy Education and Research Hospital Burn Center. A questionnaire which was developed by the researchers was used for collecting data. The questions on the questionnaire were classified into four groups to evaluate the patients and #8217; expectations about communication, information, care and discharge. Data was evaluated by using SPSS 12 package software. RESULTS: In this study, 48.5% of patients were at 18-28 age group, 79.2% were male and 51.5% of patients were employed. Almost all of patients expect nurses to give them confidence (98% and to give them information about latest developments with the disease. Patients prior expectation from nurses about care was to do their treatments regularly (100% and to take the necessary precautions in order to prevent infection (100%. 97% of patient expect nurses to give them information about the drugs, materials and equipment that they are going to use while discharge. CONCLUSION: As a result we found that burn patient expectations from nurses about communication, information, care and discharge were high. [TAF Prev Med Bull 2014; 13(1.000: 37-46

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

    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.

    Burn injury is associated with a high incidence of death and disability; yet its management remains problematic and costly. We conducted this clinical study to evaluate the efficacy of aloe vera cream for partial thickness burn wounds and compare its results with those of silver sulfadiazine (SSD). Thirty patients with similar types of second-degree burns at two sites on different parts of the body were included in this study. Each patient had one burn treated with topical SSD and one treated with aloe cream, randomly. The rate of re-epithelialization and healing of the partial thickness burns was significantly faster in the site treated with aloe than in the site treated with SSD (15.9 +/- 2 vs 18.73 +/- 2.65 days, respectively; P cream over SSD cream for treating second-degree burns.

    Pediatric scald burns result in frequent emergency room visits and hospitalizations. We investigated whether cooking-related burns produce greater morbidity requiring more extensive care than noncooking burns. We performed a 6-y review at our free-standing children's hospital. Children aged burns were included. Demographics, injury pattern, treatment, and outcome (contractures and/or limited mobility and nonhealing and/or infected wounds) data were analyzed comparing cooking versus noncooking burns. The Mann-Whitney U test, a chi-square test, and the negative binomial were used to compare continuous, categorical, and count data between groups. Bivariate analysis was performed to identify risk factors among patients with adverse outcomes. We identified 308 patients; 262 (85%) cooking and 46 (15%) noncooking burns. Most patients were African-American males, with public insurance, and a median age of 2 y. Cooking burns preferentially occurred over the head, neck, and upper body; noncooking burns were distributed over the lower body (P  0.11). In subgroup analysis, semisolid and grease burns resulted in increased rates of wound contractures and/or limited mobility when compared with noncooking burns (P = 0.05 and P = 0.008, respectively). Patients with complications were more likely to have third degree burns and required more consults, longer hospitalization, and more surgical debridements and clinic visits. Most accidental scald burns occurred in young children during food preparation. Greater long-term morbidity was found in patients with semisolid and grease burns. This subset of children has a higher injury burden and requires extensive care in the acute and long-term setting. Copyright © 2015 Elsevier Inc. All rights reserved.

    In China, large sample research directed at the epidemiology of burns is still scarce. Given the leading position of Chinese military hospitals in domestic clinical practice pertaining to burns, a look into their cases would help shed light on the incidence and hospital care of burns in China today. Data were collected from information systems of all the Chinese military hospitals, for the years 2001-2007 inclusive. Retrospective analyses on the epidemiology characteristics of burns from those in patients admitted to all the Chinese military hospitals within this period were conducted. A total of 172,256 cases were studied, with a total number of 1384 fatalities, and the median length of hospital stay (LOS) 11.00 days (interquartile range 6.00-19.00 days). Rate of burn incidence remained high in May, June, July and August. Children of preschool aged and adults in the labor force were at the highest risk of injury. Scalds constituted the majority of injuries (80.5%). Multiple body site burns are the most commonly seen category (31.98%) in terms of injured body region distribution. In fire-related burns, major burns (TBSA>30%) represented a significant proportion. Males with TBSA>30%, fire-related burns resulted in the greatest number of fatalities. Gender, age, site of injury, burn size and outcome are all correlated with the length of hospitalization. Although this paper cannot provide information on population estimates of burns due to the absence of data on burns attending civilian hospitals, it finds that the epidemiology of burns in China shows distinct characteristics compared with previous studies of other country and regions, including that of other developing or low and middle-income countries (LMICs), irrespective of China's inclusion in that group.

    1990-09-21

    Results covering burn intensities in the nW to {mu}W/cm{sup 2} range, of dispersive hole growth kinetics are reported for Oxazine 720 in glycerol glasses and polyvinyl alcohol polymer films and their deuterated analogues. A theoretical model which employs a distribution function for the hole burning rate constant based upon a Gaussian distribution for the tunnel parameter is shown to accurately describe the kinetic data. This model incorporates the linear electron-phonon coupling. A method for calculating the nonphotochemical quantum yield is presented which utilizes the Gaussian distribution of tunnel parameters. The quantum yield calculation can be extended to determine a quantum yield as a function of hole depth. The effect of spontaneous hole filling is shown to be insignificant over the burn intensity range studied. Average relaxation rates for hole burning are {approximately}8 orders of magnitude greater than for hole filling. The dispersive kinetics of hole burning are observed to be independent over the temperature range of these experiments, 1.6 to 7.0 K. 6 refs., 20 figs., 1 tab.

    Full Text Available INTRODUÇÃO: O declínio no número de autópsias em hospitais e instituições universitárias é evento amplamente reportado, inicialmente em países do primeiro mundo e posteriormente em muitos países em desenvolvimento, como o Brasil. As causas para essa tendência são múltiplas e complexas, incluindo aspectos religiosos, familiares e médicos. Entre estes últimos, salientam-se razões diagnósticas, caracterizadas pelo significativo avanço tecnológico na imagenologia, com a suposição de que todos os diagnósticos agora podem ser feitos em vida, e a crescente ansiedade de processos judiciais contra médicos por má prática. OBJETIVO: Demonstrar o decréscimo vertiginoso e drástico do número de autópsias em um hospital universitário no Brasil.

  8. Burning mouth syndrome: Current concepts

    Directory of Open Access Journals (Sweden)

    Cibele Nasri-Heir

    2015-01-01

    Full Text Available 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.

    The purpose of this study was to investigate exercise behaviors in adult burn survivors and to identify barriers to exercise in this population. A two-page questionnaire developed by the authors was administered on a single occasion to adults attending the ambulatory burns clinic at a metropolitan hospital. Data from 68 adult burn survivors were analyzed. Within this cohort, 59% of subjects reported exercising several times per week or more and the remaining 41% exercised once per week or less. There was no correlation among exercise frequency and age, TBSA, or hospital length of stay. Walking was the most common type of exercise, and subjects reported lower compliance with stretching and strengthening exercises. Physical condition and motivation were identified as the main barriers to exercise. Although this preliminary study reveals that a higher proportion of burn survivors engage in exercise compared with their healthy counterparts, a substantial number are exercising just once per week or less, below the recommended guidelines to improve physical fitness. Physical and occupational therapists play an important role in providing exercise prescription and education, as well as addressing barriers to exercise in burn survivors. The potential for further research into physical activity across all domains of life using a validated questionnaire is identified.

    After scalds, flame burns have been considered the next most common mode of burn injury in childhood. Recent experience in the authors' unit suggested that contact burns were becoming more frequent. The authors sought to determine the contemporary frequency of different burn modalities in children presenting to a burns unit. A retrospective review of 3621 children treated in the burns unit, both ambulatory and inpatient, at the authors' institution between January 2003 and December 2007 was performed. Patients were identified using the Burns Unit database. Data collected included age, gender, burn etiology and site, TBSA, and whether operative surgery was required. Of the 3515 patients eligible for inclusion, scalds accounted for 55.9%, contact 30.5%, and flame 7.9% of all burns. Contact burns were shown to be consistently more frequent than flame burns for every year of the study (z = 17.30, P burns, reflecting the variety of mechanisms involved. The data suggest a change in the historical pattern of pediatric burns previously reported in the literature. These findings have implications for public health awareness and burns prevention campaigns.

    Inflicted burns are one of the leading causes of abuse-related fatalities in children. Between 30 and 60% of children accidentally returned to abusive homes suffer reabuse. Given the high chance for abuse recurrence and the associated morbidity/mortality, it is critical that inflicted burns are promptly identified to guide appropriate medical and child welfare management. Although previous studies proposed historical and mechanistic features using noncomparative or poorly powered data, this study utilized comparative data from a 6-year period (2009-2014) at a certified burn center along with expert analysis from Child Advocacy and Protective Services (CAPS) to provide higher level evidence supporting classical findings while elucidating new features with respect to burn severity and required interventions. A retrospective chart review of 408 pediatric burns was cross-referenced with the respective CAPS consultations to construct a multidisciplinary, deidentified database. The average age was 2.9 years (0.04-17 years) with 232 (57%) males and 330 (81%) African-Americans. CAPS investigations confirmed burn etiologies: noninflicted (346 [85%]), negligent (30 [7%]), and inflicted (32 [8%]). In comparing the three etiologies, statistical significance (P burn age, child welfare history, burn size and depth, distribution, concomitant injury rates, number of surgical interventions, infectious complications, and hospital length of stay. In addition to reaffirming classical features of abusive burns to fortify etiologic diagnoses, this study elucidated appreciable differences in burn severity, interventional sequelae, and burn-related complications, which will help guide medical and surgical interventions for future pediatric burn patients.

    Typically, burn wound infections are classified by the organisms present in the wound within the first several days following injury or later, by routine surveillance cultures. With universal acceptance of early excision and grafting, classification of burn wound colonization in unexcised burn wounds is less relevant shifting clinical significance to open burn-related surgical wound infections (SWI). To better characterize SWIs and their clinical relevance, we identified the pathogens responsible for SWIs, their impact on rates of regrafting, and the relationship between SWI and nosocomial infection (NI) pathogens. Epidemiologic and clinical data for 71 adult patients with ≥20% TBSA burn were collected. Following excision and grafting, if a grafted site had clinical characteristics of infection, a wound culture swab was obtained and organism identified. Surveillance cultures were not obtained. SWI pathogen, anatomic location, post-burn day of occurrence and need for regrafting were compiled. A positive culture obtained from an isolated anatomic location at any time point after excision and grafting of that location was considered a distinct infection. Pathogens responsible for NIs (urinary tract infections, pneumonia, bloodstream and catheter-related bloodstream infections, pseudomembranous colitis and donor site infections) and their post-burn day were identified. The profiles of SWI pathogens and NI pathogens were then compared. Of the 71 patients included, 2 withdrew, 6 had no excision or grafting performed and 1 had incomplete data. Of the 62 remaining, 24 (39%) developed a SWI. In these 24 patients, 70 distinct infections were identified of which 46% required regrafting. Candida species (24%), Pseudomonas aeruginosa (22%), Serratia marcescens (11%) and Staphylococcus aureus (11%) comprised the majority of pathogens. The development of a SWI with the need for regrafting increased overall length of stay, area of autograft, number of operative events and was

    SEPS or burnout syndrome was described among health care workers. Oncology care givers--physicians and nurses--can be concerned. Burnout is a chronical stress reaction. Emotional exhaustion and depersonalisation are more prevalent than low personal accomplishment. Burnout is essentially assessed by questionnaires. Oncologists report an higher level of burnout, than AIDS medical or palliative care staff. Causes of burn out are numerous: insufficient personal time, sense of failure,... followed by poorly management and difficulties in staff or institution relationships. Prevention and therapy of burn out can be considered on three levels: personal, (psychotherapy, advices on health way of life), team (improvement in communication) and institution (support meetings and talking groups).

    Objective: To investigate and evaluate the epidemiological characteristics of patients under 14 with large area burns in China. Methods: Data of pediatric patients aged 0-14yr with ≥30% total body surface area (TBSA) burned admitted into 106 burn centers in the mainland of China in 2014 were retrieved. The children were divided into three age groups: 0-3, 4-6 and 7-14 years according to the age. Information of age, gender, time of burn injury, causes of burns, admission time, prehospital emergency care of burn wound, burn area, inhalation injuries, the case fatality rate and length of hospital stay were collected for analysis. Results: Of the 486 cases included, 285 (58.6%) were boys and 201 (41.4%) were girls. The mean age of the children was (3.4±2.8) years. Children under 3 years old accounted for 67.5% of all the cases. 271 of the burn injuries (55.8%) occurred from April through August. Scalds and flames were the main causes of burns, which were the causes of 394 cases (81.1%) and 71 cases (14.6%), respectively. The burn injuries resulted from scalds and flames accounted for 89.6% and 7.3%, 70.8% and 21.9%, 51.6% and 41.9% in the age group of 0-3, 4-6 and 7-14 years respectively. The distribution of burn etiology in different age groups differed significantly (χ(2)=21.239, 59.442, 7.333, all Parea of 236 patients (48.6%) were treated improperly with toothpaste, soy sauce, eggs or other non-standard disposal. The mean TBSA area of the patients was (42.1±14.5)%, while 288 (59.3%) of the patients suffered full thickness burns with mean TBSA of (24.5±17.9)%. The case fatality rate (CFR) was 4.1%, and the CFR of patients complicated with inhalation injury was significantly higher than those without (P<0.01). The average length of stay for pediatric burn patients was (52.3±40.2) days. Conclusions: Children under 3 years old are important target population of severe burns. Scald is the most common type of burns, while the proportion of flames increases as age

    Catabolism and lean body mass losses in severe burn injury present an extreme challenge to the dietitian. A high level of nutritional intervention is often required, but service levels have not been described in the UK. This study aimed to identify levels of current dietetic services with respect to burns and to assess adequacy against existing nutrition support standards. A postal survey of 34 UK dietetic departments known to provide care to burned adult and paediatric admissions was undertaken. Data were collected on burns settings, hospital service characteristics, staffing and caseload issues, and absence cover. Comparison was made between funding and activity to National Health Service standards for the nutritional care of inpatients. The response rate was 71% and data were analysed for 20 departments Clinical settings were either burn units or plastic surgery wards. Dietetic care was provided to critically ill burned patients in 16 hospitals. Most hospitals had no dietetic funding assigned for burn care. The funding deficit for critical care compared to recommendations was 5.9 full-time equivalents and no individual hospital met funding standards. Thirty-seven percent of dietitians were unable to provide daily follow up for critically ill patients. Absence cover was limited in 60% of cases. Approximately one-third of dietitians were members of a nutrition support team. Compared to national guidelines for nutrition support, deficiencies of dietetic service provision exist within UK burns settings. This is further reinforced when practice is compared with existing multi-professional burns management standards.

    This study aims to analyse the epidemiology of paediatric burns in south central China, illustrate the differences between rural and urban areas, and discern prevention measures to reduce paediatric burns. Data were obtained from all paediatric patients admitted to Department of Burns unit of Xiangya Hospital during 2009-2012. A retrospective review was performed, including cause of burn, pre-hospital treatment, place of burn occurrence, anatomical areas involved, extent of burn, date of injury, number of operations, complications, length of hospital stay, hospitalisation cost and cure rate. A total of 278 hospitalised paediatric patients were admitted in this study. The majority (56.47%) were 1-3 years old. Rural patients accounted for 67.99% in total; the ratio of boys to girls was 2.05. Scalding with hot fluids was the most common cause of burns in children (62.59%), followed by flame (17.63), fireworks (9.71%), electricity (5.76%) and other factors such as contact and chemical (4.32%). The living room was the location with the highest frequency of burns in children (53.24%). Burns were more likely to happen in winter and the upper extremities were the most involved anatomic site (53.24%). Total burn surface area (TBSA) ranging from 0% to 9% accounted for 55.4% in total. Rural patients underwent more operations and had longer and costlier hospital stays than urban patients. Compared with treatment in urban areas, rural burn patients received less first-aid treatment, underwent more surgery, had more complications and longer and more costly hospital stays. This finding strongly suggests that it is necessary to make more efforts to prevent burns, especially in rural areas. Copyright © 2013 Elsevier Ltd and ISBI. All rights reserved.

  5. Health effects of smoke from planned burns: a study protocol

    Full Text Available Abstract Background Large populations are exposed to smoke from bushfires and planned burns. Studies investigating the association between bushfire smoke and health have typically used hospital or ambulance data and been done retrospectively on large populations. The present study is designed to prospectively assess the association between individual level health outcomes and exposure to smoke from planned burns. Methods/design A prospective cohort study will be conducted during a planned burn season in three locations in Victoria (Australia involving 50 adult participants who undergo three rounds of cardiorespiratory medical tests, including measurements for lung inflammation, endothelial function, heart rate variability and markers of inflammation. In addition daily symptoms and twice daily lung function are recorded. Outdoor particulate air pollution is continuously measured during the study period in these locations. The data will be analysed using mixed effect models adjusting for confounders. Discussion Planned burns depend on weather conditions and dryness of ‘fuels’ (i.e. forest. It is potentially possible that no favourable conditions occur during the study period. To reduce the risk of this occurring, three separate locations have been identified as having a high likelihood of planned burn smoke exposure during the study period, with the full study being rolled out in two of these three locations. A limitation of this study is exposure misclassification as outdoor measurements will be conducted as a measure for personal exposures. However this misclassification will be reduced as participants are only eligible if they live in close proximity to the monitors.

  6. Observing the Peripheral Burning of Cigarettes by an Infrared Technique

    Full Text Available A modern infrared camera was used to observe the peripheral burning of cigarettes during puffing and smouldering. The computer-controlled infrared system captured thermal images with recording rates up to 50 Hz at 8-bit (256-colour resolution. The response time was less than 0.04 s at ca. 780 °C. The overall performance of the system was superior to most infrared systems used in previously reported investigations. The combined capacity allowed us to capture some faster, smaller high-temperature burning events on the periphery of a cigarette during puffing, which was first described by Egertion et al. in 1963 using an X-ray method. These transient burning events were caused by tobacco shreds near the coal surface experiencing the maximum air influx. The temperature of these transient burning events could be ca. 200 to 250 °C higher than the average peripheral temperature of the cigarette. The likelihood of these high-temperature burning events occurring during smouldering was significantly less. Some other details of the cigarette's combustion were also observed with improved simplicity and clarity.

    Full Text Available 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.

    Infection is a major problem in burn care and especially when it is due to bacteria with hospital-acquired multi-resistance to antibiotics. Moreover, when these bacteria are Gram-negative organisms, the most effective molecules are 20 years old and there is little hope of any new product available even in the distant future. Therefore, it is obvious that currently available antibiotics should not be misused. With this aim in mind, the following review was conducted by a group of experts from the French Society for Burn Injuries (SFETB). It examined key points addressing the management of antibiotics for burn patients: when to use or not, time of onset, bactericidia, combination, adaptation, de-escalation, treatment duration and regimen based on pharmacokinetic and pharmacodynamic characteristics of these compounds. The authors also considered antibioprophylaxis and some other key points such as: infection diagnosis criteria, bacterial inoculae and local treatment. French guidelines for the use of antibiotics in burn patients have been designed up from this work. Copyright © 2009 Elsevier Ltd and ISBI. All rights reserved.

  1. Unstable Helium Shell Burning on Accreting White Dwarfs

    2009-07-01

    AM Canum Venaticorum (AM CVn) binaries consist of a degenerate helium donor and a helium, C/O, or O/Ne white dwarf accretor, with accretion rates of \\dot{M} = 10^{-13}\\--10^{-5} \\, M_\\odot \\; yr^{-1}. For accretion rates thermonuclear supernovae. In this paper, we study the evolution of the He-burning shells in more detail. We calculate maximum achievable temperatures as well as the minimum envelope masses that achieve dynamical burning conditions, finding that AM CVn systems with accretors gsim0.8 M sun will undergo dynamical burning. Triple-α reactions during the hydrostatic evolution set a lower limit to the 12C mass fraction of 0.001-0.05 when dynamical burning occurs, but core dredge-up may yield 12C, 16O, and/or 20Ne mass fractions of ~0.1. Accreted 14N will likely remain 14N during the accretion and convective phases, but regardless of 14N's fate, the neutron-to-proton ratio at the beginning of convection is fixed until the onset of dynamical burning. During explosive burning, the 14N will undergo 14N(α, γ)18F(α, p)21Ne, liberating a proton for the subsequent 12C(p, γ)13N(α, p)16O reaction, which bypasses the relatively slow α-capture onto 12C. Future hydrodynamic simulations must include these isotopes, as the additional reactions will reduce the Zel'dovich-von Neumann-Döring length, making the propagation of the detonation wave more likely.

    2004-01-01

    Scald burns continue to be the major cause of injury to patients admitted to the burn center. Scald burns occurring from car radiator fluid comprise a significant subgroup. Although manufacturer warning labels have been placed on car radiators, these burns continue to occur. This retrospective review looks at all patients admitted to our burn center who suffered scald burns from car radiator fluid to assess the extent of this problem. During the study period, 86 patients were identified as having suffered scald burns as a result of contact with car radiator fluid. Seventy-one percent of the burn injuries occurred in the summer months. The areas most commonly burned were the head and upper extremities. Burn prevention efforts have improved greatly over the years; however, this study demonstrates that scald burns from car radiator fluid continue to cause physical, emotional, and financial devastation. The current radiator warning labels alone are not effective. The National Highway Traffic Safety Administration has proposed a new federal motor vehicle safety standard to aid in decreasing the number of scald burns from car radiators. The results of this study were submitted to the United States Department of Transportation for inclusion in a docket for federal legislation supporting these safety measures.

In addition, one oogram of the rectal mucosa was performed. By these methods, schistosomiasis was detected in 44.7%, 47.5% and 40.1% of the individuals respectively. To evaluate the methods in the assessment of cure, the last 40 patients from group A, treated with a single oral dose of oxamniquine at 15 mg/kg were followed up for six months (Group B. The criteria for parasitological cure included three stool examinations by Kato/Katz and Lutz/HPJ methods, one, three and six months post-treatment and a rectal biopsy between the fourth and sixth months post-treatment. The examinations were negative in 87.5%, 90% and 95% of the patients, respectively. The efficacy of oxamniquine was 82.5% when the three methods were considered together and there was no statistically significant difference between the sensitivity of the individual methods.Em um grupo de 217 adultos do sexo masculino selecionados através de ELISA ou intradermoreação, realizaram-se seis exames de fezes pelos métodos de Lutz/Hoffman, Pons e Janer (Lutz/HPJ e Kato/Katz e um oograma da mucosa retal, observando-se positividade em 44,7%, 47,5% e 40,1%, respectivamente.

  8. Burn-induced stimulation of lysosomal enzyme synthesis in skeletal muscle

    Energy Technology Data Exchange (ETDEWEB)

    Odessey, R.

    1986-05-01

    A localized burn injury to a rat hindlimb results in atrophy of soleus muscle (in the absence of cellular damage) which is attributable to an increase in muscle protein breakdown. Previous work has shown that lysosomal enzyme activities (cathepsins B, H, L, and D) are elevated in muscle from the burned leg by 50% to 100%. There is no change in endogenous neutral protease activity (+/- Ca/sup + +/). The increase in protease activity can not be attributed to changes in endogenous protease inhibitors. The latency ((Triton X100 treated - control)/triton treated) of lysosomal enzymes is approximately 50% and is not altered by burn injury. The rate of sucrose uptake is also not altered by burn. These experiments suggest that the rate of substrate supply to the lysosomal apparatus via endocytosis or autophagocytosis is not altered by burn. When muscles are preincubated with /sup 3/H-phenylalanine or /sup 3/H-mannose burn increased incorporation into protein of the fraction containing lysosomes by 100%. Preincubation in the presence of tunicamycin (an inhibitor of glycoprotein synthesis) inhibited incorporation of both labels into a microsomal fraction of the muscle from the burned leg, but has little effect on incorporation in the control muscle. These findings are consistent with the hypothesis that the burn-induced increase in protein breakdown is caused by an increase in lysosomal protease synthesis.

  9. Spectral hole burning studies of photosystem II

    Energy Technology Data Exchange (ETDEWEB)

    Chang, Hai -Chou [Iowa State Univ., Ames, IA (United States)

    1995-09-26

    Low temperature absorption and hole burning spectroscopies were applied to the D1-D2-cyt b559 and the CP47 and CP43 antenna protein complexes of Photosystem H from higher plants. Low temperature transient and persistent hole-burning data and theoretical calculations on the kinetics and temperature dependence of the P680 hole profile are presented and provide convincing support for the linker model. Implicit in the linker model is that the 684-nm-absorbing Chl a serve to shuttle energy from the proximal antenna complex to reaction center. The stoichiometry of isolated Photosystem H Reaction Center (PSII RC) in several different preparations is also discussed. The additional Chl a are due to 684-nm-absorbing Chl a, some contamination by the CP47 complex, and non-native Chl a absorbing near 670 nm. In the CP47 protein complex, attention is focused on the lower energy chlorophyll a Qy-states. High pressure hole-burning studies of PSII RC revealed for the first time a strong pressure effect on the primary electron transfer dynamics. The 4.2 K lifetime of P680*, the primary donor state, increases from 2.0 ps to 7.0 ps as pressure increases from 0.1 to 267 MPa. Importantly, this effect is irreversible (plastic) while the pressure induced effect on the low temperature absorption and non-line narrowed P680 hole spectra are reversible (elastic). Nonadiabatic rate expressions, which take into account the distribution of energy gap values, are used to estimate the linear pressure shift of the acceptor state energy for both the superexchange and two-step mechanisms for primary charge separation. It was found that the pressure dependence could be explained with a linear pressure shift of ~1 cm-1/MPa in magnitude for the acceptor state. The results point to the marriage of hole burning and high pressures as having considerable potential for the study of primary transport dynamics in reaction centers and antenna complexes.

    This review was an effort to systematically examine the nationwide data available on pediatric burns requiring hospitalization to reveal burn epidemiology and guide future education and prevention. The China Biomedical Disk Database, Chongqing VIP Database, and China Journal Full-Text Database were searched for articles reporting data on children and their burns from January 2000 through December 2005. Studies were included that systematically investigated the epidemiology of pediatric burns requiring hospitalization in China. Twenty-eight articles met the inclusion criteria, all of which were retrospective analyses. For each study included, 2 investigators independently abstracted the data related to the population description by using a standard form and included the percentage of patients with burn injury who were burn; anatomical sites of burn; severity of burn; and mortality and cause of death. These data were extracted, and a retrospective statistical description was performed with SPSS11.0 (SPSS Inc, Chicago, IL). Of the pediatric patients studied, the proportion of children with burn injury ranged from 22.50% to 54.66%, and the male/female ratio ranged from 1.25:1 to 4.42:1. The ratio of children aged 3 years was 0.19:1 to 4.18:1. The rural/urban ratio was 1.60:1 to 12.94:1. The ratio of those who were burned indoors versus outdoors was 1.62 to 17.00, and there were no effective hints on the distribution of seasons and anatomical sites of burn that could be found. The peak hours of pediatric burn were between 17:00 and 20:00. Most articles reported the sequence of reasons as hot liquid > flame > electricity > chemical, and scalding was, by far, the most predominant reason for burn. The majority of the studies reported the highest proportion involved in moderate burn, and the lowest proportion was for critical burn. The mortality rate ranged from 0.49% to 9.08%, and infection, shock, and multiple organ dysfunction syndrome were the most common causes of

    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.

    Full Text Available The hand is ranked among the three most frequent sites of burns scar contracture deformity. One of the major determinants of the quality of life in burns survivors is the functionality of the hands. Burns deformities, although largely preventable, nevertheless do occur when appropriate treatment is not provided in the acute situation or when they are part of a major burns. Reconstructive procedures can greatly improve the function of the hands. Appropriate choice of procedures and timing of surgery followed by supervised physiotherapy can be a boon for a burns survivor.

    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

    Burns to the perineum are frequently exposed to faeces. Diverting colostomy is often described to prevent faecal soiling. Because this technique is invasive with frequent complications, use of non-surgical devices including specifically designed faecal management systems has been reported in perineal burns. In order to standardise the faecal management strategy in patients with perineal burns, a group of French experts was assembled. This group first evaluated the ongoing practice in France by analysing a questionnaire sent to every French burn centre. Based on the results of this study and on literature data, the experts proposed recommendations on the management of perineal burns in adults. Specifically designed faecal management systems are the first-line method to divert faeces in perineal burns. The working group proposed recommendations and an algorithm to assist in decisions in the management of perineal burns in four categories of patients, depending on total burn skin area, depth and extent of the perineal burn. In France, non-surgical devices are the leading means of faecal diversion in perineal burns. The proposed algorithm may assist in decisions in the management of perineal burns. The expert group emphasises that large clinical studies are needed to better evaluate these devices. Copyright © 2013 Elsevier Ltd and ISBI. All rights reserved.

    Chemical burns account for a small proportion of total burns in children, but may require specific first aid and different modes of prevention. A retrospective study between 2006 and 2012 of children ≤16 years treated with chemical burns at a specialist paediatric burn centre. Data were extracted from a prospectively maintained database. 56 episodes of chemical burns occurred during the study period. The majority (54%) occurred in boys. There were 39 (72%) patients chemical burns occurred in the domestic setting, especially in the chemicals by an unattended child accounted for half of all (n=22, 49%) chemical burns burns in patients ≥10 years resulted from self-harm. The most common aetiological agents were household cleaners and aerosols in the younger and older age groups respectively. Chemical burns remain infrequent but potentially preventable. These burns mainly occur in the domestic setting due to non-intentional exposure of household chemicals in children burns in children <10. Crown Copyright © 2014. Published by Elsevier Ltd.

    In 2009, the Victoria Department of Sustainability and Environment estimated approximately 430,000 hectares of Victoria Australia were burned by numerous bushfires. Burned Area Emergency Response (BAER) teams from the United States were deployed to Victoria to assist local fire managers. The U.S. Geological Survey Earth Resources Observation and Science Center (USGS/EROS) and U.S. Forest Service Remote Sensing Applications Center (USFS/RSAC) aided the support effort by providing satellite-derived "soil burn severity " maps for over 280,000 burned hectares. In the United States, BAER teams are assembled to make rapid assessments of burned lands to identify potential hazards to public health and property. An early step in the assessment process is the creation of a soil burn severity map used to identify hazard areas and prioritize treatment locations. These maps are developed primarily using Landsat satellite imagery and the differenced Normalized Burn Ratio (dNBR) algorithm.

    2010-09-30

    Radiation injuries are usually caused by radioactive isotopes in industry. Detonations of nuclear reactors, the use of military nuclear weapons, and terrorist attacks represent a risk of mass burn casualties. Ionizing radiation creates thermal burns, acute radiation syndrome with pancytopenia, and a delayed cutaneous syndrome. After a latency period, skin symptoms appear and the depth of tissue damages increase with dose exposure. The usual burn resuscitation protocols have to be applied. Care of these victims also requires assessment of the level of radiation, plus decontamination by an experienced team. In nuclear disasters, the priority is to optimize the available resources and reserve treatment to patients with the highest probability of survival. After localized nuclear injury, assessment of burn depth and surgical techniques of skin coverage are the main difficulties in a burn centre. Training in medical facilities and burn centres is necessary in the preparation for management of the different types of burn injuries.

    2009-07-01

    Young children often use their hands for exploration of their surroundings, and this often leads to the hand being the primary site of injury. Because of this and many associated factors, burns of the pediatric hands are relatively common, with thermal injuries being the most frequent. Electrical and chemical etiologies contribute a minor portion of the burn injuries in the pediatric population. Some key differences should be considered in the management of hand burns in a pediatric patient versus an adult. In general, minor superficial burns will heal satisfactorily only with topical care. Deeper partial-thickness and full-thickness burns, however, require surgical interventions. Special care should always be taken in the management of electrical and chemical burns because the pathophysiology of these injuries are unique. Treatment of pediatric hand burns should also involve close and thorough follow-up to assess not only for healing and restoration of function of the injury but also for psychologic and emotional trauma.

    Full Text Available Burning mouth syndrome is a condition characterized by chronic orofacial pain without any mucosal abnormalities or other organic disease. There are numerous synonyms for this ailment such as stomatodynia, stomatopyrosis, glossodynia, glossopyrosis, sore mouth, sore tongue, oral dysesthesia, and scalding mouth syndrome. Patients usually present with burning, stinging, or numbness on the tongue or other areas of oral mucosa. The complex etiology and lack of characteristic signs and symptoms makes the diagnosis difficult. As a result of which managing such patients become a herculean task. Moreover, lack of understanding of the disease leads to misdiagnosis and unnecessary referral of patients. In this article, the authors have described the etiopathogenesis, diagnostic algorithm and management of this confusing ailment.

    This paper presents a retrospective study of the use of 346 expanders in 132 patients operated at the Ivo Pitanguy Clinic, between the period of 1985 and 2000. The expanders were used in the treatment of burn sequela. In the majority of cases, more than one expander was used at the same time. In 42 patients, repeated tissue expansion was done. The re-expanded flaps demonstrated good distension and viability. With the increase in area at each new expansion, larger volume expanders were employed, achieving an adequate advancement of the flaps to remove the injured tissue. The great advantage of using tissue re-expansion in the burned patient is the reconstruction of extensive areas with the same color and texture of neighboring tissues, without the addition of new scars.

    Background: Many people suffer from burn injuries every year, and burns make the patients undergo surgeries and years of rehabilitation. Burns lead to more years of disability, compared to cancer or heart diseases. Epidemiologic studies are needed to reveal the span, impact, and related factors of burns to help take appropriate efforts to reduce its mortality and morbidity. Materials and Methods: This study was conducted in two phases. The first phase was a descriptive retrospective study conducted on 836 burn patients who were admitted to the main special burn hospital of Isfahan, Iran. Data were collected from archived patients’ files using a checklist approved by the faculties of epidemiology and nursing. In the second phase, a survey was done based on the professional task checklist of burn ward nurses to assess the fulfillment of each task by the nurses. Results: Burns were found to occur more among those in the age groups of 20-30 (26.2%) and 0-10 years (22.9%). The most common causes of burns were flammables and gas explosions due to imprudence at home and workplaces, or self-infliction. Mortality rate was 21.7% due to sepsis, shock, and inhalation injuries, respectively. Nurses gave 19.78 out of 50 points (39.56%) to their performance in the prevention of sepsis. Conclusions: Based on the findings of this study, it can be concluded that there is still an increasing need for safety education and using environmental safety measures, as well as developing high-quality methods to transport burn patients and administer care to decrease the mortality and morbidity associated with burns.

    Kaufman, Yoram J.; Fraser, Robert S.; Mahoney, Robert L.

    1991-01-01

    The basic theory of the effect of pollution on cloud microphysics and its global implications is applied to compare the relative effect of a small increase in the consumption rate of oil, coal, or biomass burning on cooling and heating of the atmosphere. The characteristics of and evidence for the SO2 induced cooling effect are reviewed. This perturbation analysis approach permits linearization, therefore simplifying the analysis and reducing the number of uncertain parameters. For biomass burning the analysis is restricted to burning associated with deforestation. Predictions of the effect of an increase in oil or coal burning show that within the present conditions the cooling effect from oil and coal burning may range from 0.4 to 8 times the heating effect.

    We present the first detailed 3D hydrodynamic implicit large eddy simulations of turbulent convection of carbon burning in massive stars. Simulations begin with radial profiles mapped from a carbon-burning shell within a 15 M⊙ 1D stellar evolution model. We consider models with 1283, 2563, 5123, and 10243 zones. The turbulent flow properties of these carbon-burning simulations are very similar to the oxygen-burning case. We performed a mean field analysis of the kinetic energy budgets within the Reynolds-averaged Navier-Stokes framework. For the upper convective boundary region, we find that the numerical dissipation is insensitive to resolution for linear mesh resolutions above 512 grid points. For the stiffer, more stratified lower boundary, our highest resolution model still shows signs of decreasing sub-grid dissipation suggesting it is not yet numerically converged. We find that the widths of the upper and lower boundaries are roughly 30 per cent and 10 per cent of the local pressure scaleheights, respectively. The shape of the boundaries is significantly different from those used in stellar evolution models. As in past oxygen-shell-burning simulations, we observe entrainment at both boundaries in our carbon-shell-burning simulations. In the large Péclet number regime found in the advanced phases, the entrainment rate is roughly inversely proportional to the bulk Richardson number, RiB (∝RiB-α, 0.5 ≲ α ≲ 1.0). We thus suggest the use of RiB as a means to take into account the results of 3D hydrodynamics simulations in new 1D prescriptions of convective boundary mixing.

    Ocular chemical burns are common and serious ocular emergencies that require immediate and intensive evaluation and care. The victims of such incidents are usually young, and therefore loss of vision and disfigurement could dramatically affect their lives. The clinical course can be divided into immediate, acute, early, and late reparative phases. The degree of limbal, corneal, and conjunctival involvement at the time of injury is critically associated with prognosis. The treatment starts wit...

    Full Text Available Background: Burn injuries rank among the most severe types of injuries suffered by the human body with an attendant high mortality and morbidity rate. In previous studies, incidence, severity and deaths due to burn were found higher in young married women in India. Study to find out mortality pattern in burn patient was not carried out in this part of country. Objective: To identify demographic and sociocultural factors, type, modes, causes and risk factors for burn injuries and their gender-wise association. Materials and Methods: It was a retrospective study. Data were collected from all burn patients who admitted and died while on the treatment from 2004 to 2009. A total of 586 patients were included in this study. Data were gathered from hospital records and entered in the excel sheet. Analysis of data was done by using SPSS version 17 statistical software. Results: The mean age of patients was 22.66 years (range 1 m to 80 years. Episodes of burn were 4.63 times common in female (82.25% than in male (17.75%. It was statistically significant in females of age group 21-30 years (93.93% vs. 15.33% P < 0.0001. Married females (86.80% burned more commonly than married males (13.19% P < 0.0001. Flame burn was the major cause of death (95.56%. Kerosene was the most common (69% source of flame burn. Clothes caught fire while working on Chullha were 25% cases ( P < 0.0001. Accidental (86.44% burn was the most common intention of injury. The majority of burn deaths (68% occurred within one week of the incident due to septicemia (57%. Conclusion: Factors associated with an increase in mortality were accidental burns, burn size, young age, married women, and flame burns. For planning and implementing prevention programs, the approach has to be multidisciplinary and coordinated.

  15. On the Burn Topology of Hot-Spot Initiated Reactions

    Hill, Larry; Zimmermann, Bjorn

    2009-06-01

    The bulk rate of heterogeneous reaction of an energetic material depends on both the decomposition chemistry and the physical microstructure. Simple thermal decomposition models and most detonation reactive burn models express the reaction rate as the product of two functions. One expresses the sensitivity of the rate to the thermodynamic state; the other expresses the effect of reactant depletion. For a homogeneous reaction, the depletion function structure depends on the reaction pathways (overall reaction order, autocatalysis, etc.). For a heterogeneous reaction, the depletion function also depends on the reaction topology (e.g., how reaction spreads from nucleation sites to consume the material). We numerically generate depletion functions for simultaneously initiated, randomly oriented hot spots, and compare the result to the analytic solution for regularly spaced hot spots. The effect of randomization is substantial. We also compare the depletion function for ideal randomly located hot spots to those employed by various reactive burn models that are calibrated to detonation experiments.

    We evaluated the effects of cartoon viewing with the use of a star feedback chart on two burned children's pain behavior during their physical therapy sessions. In addition, the degree to which the observational data corresponded with physical therapists' and mothers' ratings of the children's pain, fear, and cooperativeness was examined. Using a reversal single-subject design, the results showed that the children's pain behavior substantially decreased during experimental treatment sessions compared to their baseline levels. The rating scale data indicated that the physical therapist's and mother's rating of pain, anxiety, and cooperativeness were all correlated significantly with the observational data (p less than .05). The contributions of respondent and operant conditioning to the occurrence and treatment of pain behavior in burned children are discussed. PMID:6735948

    Negative pressure has been employed in various aspects of burn care and the aim of this study was to evaluate the evidence for each of those uses. The PubMed and Cochrane CENTRAL databases were queried for articles in the following areas: negative pressure as a dressing for acute burns, intermediate treatment prior to skin grafting, bolster for skin autografts, dressing for integration of dermal substitutes, dressing for skin graft donor sites, and integrated dressing in large burns. Fifteen studies met our inclusion criteria. One study showed negative pressure wound therapy improved perfusion in acute partial-thickness burns, 8 out of 9 studies showed benefits when used as a skin graft bolster dressing, 1 out of 2 studies showed improved rate of revascularization when used over dermal substitutes, and 1 study showed increased rate of re-epithelialization when used over skin graft donor sites. Negative pressure can improve autograft take when used as a bolster dressing. There is limited data to suggest that it may also improve the rate of revascularization of dermal substitutes and promote re-epithelialization of skin graft donor sites. Other uses suggested by studies that did not meet our inclusion criteria include improving vascularity in acute partial-thickness burns and as an integrated dressing for the management of large burns. Further studies are warranted for most clinical applications to establish negative pressure as an effective adjunct in burn wound care. Copyright © 2016 Elsevier Ltd and ISBI. All rights reserved.

    The objective of this study was to identify the epidemiologic characteristics of childhood burns in the province of Newfoundland and Labrador. A population-based study was carried out on children aged 0-16 years who were hospitalized due to burns in Newfoundland and Labrador between April 1995 and March 2001. Hospital and mortality data were obtained from the provincial hospital admission database and Mortality System, respectively. The Newfoundland and Labrador population was considered as a whole and as two separate geographic areas. A total of 157 hospital admissions due to burns were identified during the study period. The rate of burns requiring hospitalization in the province was 22.3 per 100,000 person-years (P-Y). The rates for males and females was 27.7 and 16.6 per 100,000 P-Y, respectively (P=0.006). Infants (0-1 year) had the highest rate of burn (88.8 per 100,000 P-Y) followed by children aged 2-4 years (26.0 per 100,000 P-Y) (PNewfoundland (20.3 per 100,000 P-Y) (PNewfoundland and Labrador. Study results indicate a difference in the epidemiologic pattern of burn between the island portion of the province, Newfoundland, and mainland Labrador. It is recommended that preventive programs be directed towards high risk groups to reduce the incidence of burns. Copyright © 2011 Elsevier Ltd and ISBI. All rights reserved.

    Because of the potential severity of their residual deformities, burn injuries in infants justify an early management in specialized centres when they cover more than 5% of body surface and in every case when hands, face, or external genitalia are concerned. Cooling with cold water is the first aid treatment to be performed as early as possible after the injury. The treatment in specialized centres must be both general and surgical. General treatment includes fluid and electrolyte therapy, temperature control, appropriate nutrition and pain suppression. Pain suppression is a major part of the treatment and morphine must be largely used. Surgical treatment starts as soon as the patient arrives in the centre and is eventually performed under general anesthesia: all the burned areas are covered with occlusive dressings. Infections are prevented by systematic cultures and adjusted antibiotic therapy. A vigorous rehabilitation program must be instituted as soon as possible: massages, compressive clothes, splints, physical therapy, plastic surgery. Primary prevention by sustained parental education is important in order to reduce the frequency of burn injuries in infants.

    Burns are an important health problem in our country and in the world. In our study, we aimed to epidemiologically analyze the patients who were hospitalized in a burn unit that serves 3 million individuals in Central Anatolia. Records of 457 patients who had been hospitalized in the burn unit during the period 2008-2010 were analyzed retrospectively. Patients were assessed in terms of gender, age, burn area, burn depth, admission time to the health center, burn region, and factors causing burns. Most (44.6%) of the patients were in the 0-5 age group. Burn surface area was detected as 11.6 +/- 8.5%. Patients had reached the health center in 252.8 +/- 892.5 minutes. While 82.7% of the patients had second degree bums, 17.3% had third degree burns. Most burns were on the extremities (39.6%). The most common burn agent was scalds with hot liquids (54.1%). In our study, children in the 0-5 age group were found to be the most commonly affected group with respect to indoor burns. The basic contributing factor is that children spend more time in the house and are more active. Scalding burns may be prevented when greater care is taken when using hot liquids that may lead to indoor burns. Informing parents on this issue is of first priority.

    To evaluate the role of amniotic membrane transplantation in patients with acute ocular burns. In a prospective, randomised, controlled clinical trial, 100 patients with grade II to IV acute ocular burns (Roper Hall Classification) were recruited. 50 patients with grade II-III burns were graded as moderate burns, and 50 patients with grade IV burns were graded as severe burns. Both groups were individually randomised into control group (n=25) and study group (n=25). The corresponding grade of ocular surface burn by Dua classification was noted. The eyes in the study group underwent amniotic membrane transplantation in addition to conventional medical therapy. In the control group, conventional medical therapy along with mechanical release of early adhesions as and when necessary was instituted. Rate of healing of corneal epithelial defect, visual acuity, extent of corneal vascularisation, corneal clarity and formation of symblepharon were compared in both groups. In patients with moderate ocular burns treated with amniotic membrane transplantation, the rate of epithelial healing was significantly better than the group treated with standard medical therapy alone (p=0.0004). There was no overall difference in the final visual outcome, symblepharon formation, corneal clarity and vascularisation with or without amniotic membrane transplantation. Amniotic membrane transplantation in eyes with acute ocular burns promotes faster healing of epithelial defect in patients with moderate grade burns. There seems to be no definite long-term advantage of amniotic membrane transplantation over medical therapy and mechanical release of adhesions in terms of final visual outcome, appearance of symblepharon and corneal vascularisation when compared in a controlled clinical setting.

    To combat the risk of nightwear burns a mandatory standard regulating the design, flammability and labelling requirements of children's nightwear was introduced in Australia in 1987. This population-based study examined the trends, characteristics and causes of clothing-related burns to inform a review of the current standard, and to facilitate the development of targeted prevention strategies. Clothing-related burns for 1998-2013 were identified from hospitalisation data for all hospitals in NSW and detailed information regarding circumstance of injury from a burn data registry. To investigate percentage annual change (PAC) in trends negative binomial regression analysis was performed. There were 541 hospitalisations for clothing-related burns, 18% were nightwear-related and 82% were for other clothing. All clothing burns decreased by an estimated 4% per year (95% CI -6.2 to -2.1). Nightwear-related burns decreased by a significantly higher rate (PAC -7.4%; 95% CI -12.5 to -2.1) than other clothing (PAC -2.5%; 95%CI -4.7 to -0.1). Exposure to open heat source (campfire/bonfire) was the most common cause, followed by cooking. Of factors known to be associated with clothing burns, accelerant use was reported in 27% of cases, cigarettes 17%, loose skirt or dress 8%, and angle grinders in 6% of cases. Hospitalisations for clothing burns are relatively uncommon in NSW and rates, particularly of nightwear burns, have decreased over the last 15 years. Strategies for continued reduction of these injuries include increasing the scope of the current clothing standard or developing new standards to include all children's clothing and adult nightwear, and increasing community awareness of the risk associated with open heat sources, accelerant use and loose clothing.

  4. Effects of non-equilibrium particle distributions in deuterium-tritium burning

    Energy Technology Data Exchange (ETDEWEB)

    2009-08-18

    We investigate the effects of non-equilibrium particle distributions resulting from rapid deuterium-tritium burning in plasmas using a Fokker-Planck code that incorporates small-angle Coulomb scattering, Brehmsstrahlung, Compton scattering, and thermal-nuclear burning. We find that in inertial confinement fusion environments, deviations away from Maxwellian distributions for either deuterium or tritium ions are small and result in 1% changes in the energy production rates. The deuterium and tritium effective temperatures are not equal, but differ by only about 2.5% near the time of peak burn rate. Simulations with high Z (Xe) dopants show that the dopant temperature closely tracks that of the fuel. On the other hand, fusion product ion distributions are highly non-Maxwellian, and careful treatments of energy-exchange between these ions and other particles is important for determining burn rates.

    2011-02-01

    To compare the predictive outcome of ocular burns using two different prognostic classification systems, that is, Dua and Roper Hall classification. In a prospective, randomised, controlled clinical trial, the extent of acute ocular burns in 100 patients was graded by Roper Hall and Dua classifications. Patients were randomised in two groups of 50 each to receive conventional medical therapy alone or additional amniotic membrane transplantation (AMT). Moderate burns were graded similarly (grade II and III) under both systems, while severe burns were classified differently and compared further. Baseline parameters (size of epithelial defect, corneal haze, limbal ischaemia, conjunctival involvement and visual acuity) and outcome variables (healing of epithelial defect, corneal clarity, corneal vascularisation, visual outcome and symblepharon) after 1 year were noted and compared. There was no difference in terms of time taken and rate of healing of epithelial defect, but there was a significant difference in extent of corneal vascularisation between grades IV, V and VI (pburns than either grade V (p=0.045) or grade VI (p=0.024) burns, and final visual acuity was significantly better in these patients (p=0.043). On comparison of patients with grade IV burns (with and without AMT), the outcome in terms of extent of corneal vascularisation was significantly better (p=0.0124) in patients who received AMT. Dua classification by providing further subclassification of grade IV ocular burns by Roper Hall into three separate grades has a superior prognostic predictive value in severe ocular burns.

    The US federal government invests in the development of medical countermeasures for addressing adverse health effects to the civilian population from chemical, biological, and radiological or nuclear threats. We model the potential economic spillover effects in day-to-day burn care for a federal investment in a burn debridement product for responding to an improvised nuclear device. We identify and assess 4 primary components for projecting the potential economic spillover benefits of a burn debridement product: (1) market size, (2) clinical effectiveness and cost-effectiveness, (3) product cost, and (4) market adoption rates. Primary data sources were the American Burn Association's 2015 National Burn Repository Annual Report of Data and published clinical studies used to gain European approval for the burn debridement product. The study results showed that if approved for use in the United States, the burn debridement product has potential economic spillover benefits exceeding the federal government's initial investment of $24 million a few years after introduction into the burn care market. Economic spillover analyses can help to inform the prioritizing of scarce resources for research and development of medical countermeasures by the federal government. Future federal medical countermeasure research and development investments could incorporate economic spillover analysis to assess investment options.

    2010-03-01

    This descriptive study was conducted among 130 families in Milas, Turkey, who have children ages 0 to 14 years. Among the 130 families, a total of 53 children (40.8%) experienced a burn event. Twenty-seven subjects (51%) had treated the burn with inappropriate remedies including yogurt, toothpaste, tomato paste, ice, raw egg whites, or sliced potato. Of the 28 subjects (52.8%) who had applied cold water to the burn site, 21 patients (39.6%) applied only cold water and 7 patients (13.2%) used another substance along with cold water. In addition, 13 subjects (24.5%) applied ice directly on the skin at the time of the burn. Excluding the subjects who had treated their burns with only cold water or with only ice, raw egg whites were the most commonly used agent, both alone (n = 3) or accompanied by cold water or ice (n = 6) in a total of 11 subjects (21%) who applied eggs. Based on these observations, it is suggested that educational programs emphasizing first-aid application of only cold water to burn injuries would be helpful in reducing morbidity and mortality rates. A nationwide educational program is needed to ensure that young burn victims receive appropriate first aid and to reduce the use of inappropriate home remedies and burn morbidity.

    Trifluoroacetic acid is a very strong carboxylic acid. The acid has been suspected to have similar toxic effects as hydrofluoric acid on skin contact. Hydrofluoric acid is highly toxic, owing to skin penetration by fluoride ions. A spill of hydrofluoric acid on the skin may be fatal. As trifluoroacetic acid contains fluorine, patients with chemical burns caused by trifluoroacetic acid have been given particular attention when treated in the hospital. To gather the known cases of trifluoroacetic acid burns from our department to give an overview of how they were exposed, the clinical presentation, and treatment. Five patients with chemical skin burns caused by trifluoroacetic acid were reviewed with regard to the extent of the burn, treatment, blood samples taken, and systemic effects. The chemical burns reported were limited (burns healed as expected for chemical burns caused by acids. None of the patients showed any symptoms or signs that are typical for hydrofluoric acid burns. Localized chemical burns caused by trifluoroacetic acid should be regarded as being similar to burns from other acids, with the exception of hydrofluoric acid. To our knowledge, there are no indications that trifluoroacetic acid causes the same toxic effects as hydrofluoric acid. © 2013 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    2013-03-01

    Self-inflicted burns are regularly admitted to burns units worldwide. Most of these patients are referred to psychiatric services and are successfully treated however some return to hospital with recurrent self-inflicted burns. The aim of this study is to explore the characteristics of the recurrent self-inflicted burn patients admitted to the Royal North Shore Hospital during 2004-2011. Burn patients were drawn from a computerized database and recurrent self-inflicted burn patients were identified. Of the total of 1442 burn patients, 40 (2.8%) were identified as self-inflicted burns. Of these patients, 5 (0.4%) were identified to have sustained previous self-inflicted burns and were interviewed by a psychiatrist. Each patient had been diagnosed with a borderline personality disorder and had suffered other forms of deliberate self-harm. Self-inflicted burns were utilized to relieve or help regulate psychological distress, rather than to commit suicide. Most patients had a history of emotional neglect, physical and/or sexual abuse during their early life experience. Following discharge from hospital, the patients described varying levels of psychiatric follow-up, from a post-discharge review at a local community mental health centre to twice-weekly psychotherapy. The patients who engaged in regular psychotherapy described feeling more in control of their emotions and reported having a longer period of abstinence from self-inflicted burn. Although these patients represent a small proportion of all burns, the repeat nature of their injuries led to a significant use of clinical resources. A coordinated and consistent treatment pathway involving surgical and psychiatric services for recurrent self-inflicted burns may assist in the management of these challenging patients.

    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.

    The aim of this study was to characterize the epidemiology of pediatric and adolescent burns admitted to the Children's Burns Unit at the Department of Pediatrics and Adolescent Medicine, Medical University of Graz, Austria, between January 1st 1988 and December 31st 2012. This is a retrospective review over the past 25-years and describes admission rate by gender and age groups, causes of burns, anatomical sites of burns, extent and depth of injury, length of hospital stay, child abuse and in-hospital mortality. In the studied 25 year-period, 1586 pediatric burn patients were admitted. 1451 patients were "acute" admissions, 64 "secondary" admissions and 71 patients did not fulfill the inclusion criteria. Of the 1451 patients, 930 (64%) were male and 521 (36%) female. The majority of patients - 880 or 60.6% - were children from 1 to 5 years of age. Domestic burns occurring at home resulted in 1164 (80.2%) of injuries and scalds were the most common type of thermal trauma with 945 (65.1%) patients. According to the extent of injury 1106 (76.2%) patients suffered burns of burn care over a long time period, at a single center, including children and adolescents, with stable surgical and rehabilitation staff. The data is also important for the design of prevention programs and establishment of burn care capacities, since the analysis showed no change in the incidence of burn related admissions over the time period studied.

    2010-10-01

    To explore the relationship between sources of stress and psychological burn-out and to consider the moderating and mediating role played sources of stress and different coping resources on burn-out. Most research exploring sources of stress and coping in nursing students construes stress as psychological distress. Little research has considered those sources of stress likely to enhance well-being and, by implication, learning. A questionnaire was administered to 171 final year nursing students. Questions were asked which measured sources of stress when rated as likely to contribute to distress (a hassle) and rated as likely to help one achieve (an uplift). Support, control, self-efficacy and coping style were also measured, along with their potential moderating and mediating effect on burn-out. The sources of stress likely to lead to distress were more often predictors of well-being than sources of stress likely to lead to positive, eustress states. However, placement experience was an important source of stress likely to lead to eustress. Self-efficacy, dispositional control and support were other important predictors. Avoidance coping was the strongest predictor of burn-out and, even if used only occasionally, it can have an adverse effect on burn-out. Initiatives to promote support and self-efficacy are likely to have the more immediate benefits in enhancing student well-being. Nurse educators need to consider how course experiences contribute not just to potential distress but to eustress. How educators interact with their students and how they give feedback offers important opportunities to promote self-efficacy and provide valuable support. Peer support is a critical coping resource and can be bolstered through induction and through learning and teaching initiatives. Copyright (c) 2010 Elsevier Ltd. All rights reserved.

    2012-11-01

    Nylon-reinforced silver sodium carboxymethylcellulose (AQUACEL(®) Ag BURN) dressings were developed to be pliable and conforming for the management of partial-thickness burns. This study evaluated the AQUACEL(®) Ag BURN glove for the management of hand burns. This 21-day, phase II, prospective, non-comparative study included 23 patients with partial-thickness hand burn of at least two fingers. The AQUACEL(®) Ag BURN glove was applied to one hand and could remain in place up to 21 days until clinically indicated to change the glove. Dressings were evaluated 1, 2, 4, 6, 8, 14, and 21 days after initial application. Safety was the primary study endpoint. Sixteen (70%) hand burns re-epithelialized fully over a mean of 15.6 days. Initial application was easy/very easy for 20 (87%) patients. Mean time for initial dressing application was 5.4 min. At final evaluation, most patients gave ratings of excellent/good for conformability (91%), overall glove performance (74%), and appropriateness of sizes (83%). Mean pain score from 0 (none) to 10 (worst imaginable) was 3.43 at baseline; during the study, mean scores were 1.15 at rest and 2.29 during movement. Of 61 glove removals, most (72%) were easy/very easy, and 12% had fallen off. Adverse events (wound site or elsewhere) occurred in 15 (65%) patients. Treatment-related adverse events were wound pain (17%), maceration (9%), and stiff fingers (4%). The AQUACEL(®) Ag BURN glove was well tolerated in the management of partial-thickness hand burn. Many patients used only one glove. When glove changes were required, they were usually quick and easy. Copyright © 2012 Elsevier Ltd and ISBI. All rights reserved.

  15. Health risks due to pre-harvesting sugarcane burning in São Paulo State, Brazil

    2015-09-01

    Full Text Available After 2003, a new period of expansion of the sugarcane culture began in Brazil. Pre-harvesting burning of sugarcane straw is an agricultural practice that, despite the nuisance for the population and pollution generated, still persisted in over 70% of the municipalities of São Paulo State in 2010. In order to study the distribution of this risk factor, an ecological epidemiological study was conducted associating the rates of deaths and hospital admissions for respiratory diseases, for each municipality in the State, with the exposure to the pre-harvesting burning of sugarcane straw. A Bayesian multivariate regression model, controlled for the possible effects of socioeconomic and climate (temperature, humidity, and rainfall variations, has been used. The effect on health was measured by the standardized mortality and morbidity ratio. The measures of exposure to the pre-harvesting burning used were: percentage of the area of sugarcane harvested with burning, average levels of aerosol, and number of outbreaks of burning. The autocorrelation between data was controlled using a neighborhood matrix. It was observed that the increase in the number of outbreaks of burning was significantly associated with higher rates of hospital admissions for respiratory disease in children under five years old. Pre-harvesting burning of sugarcane effectively imposes risk to population health and therefore it should be eliminated.

  16. Topical and systemic antimicrobial agents in burns.

    Ollstein, R N; McDonald, C

    1980-11-01

    Infection is the major cause of morbidity and mortality in burns. Burn wound infection is defined as burn wound bacterial proliferation in a density equal to or greater than 10(5) bacteria per gram of tissue. Gram-negative bacteria, notably Pseudomonas aeruginosa, as well as staphylococci and fungal opportunists, have been identified as prominent invaders. Topical and systemic antimicrobial agents are essential adjuncts in the prevention and treatment of burn wound infection. Topical antimicrobial therapy is indicated in all hospitalized burn patients. Short-term use of systemic antimicrobials for prophylaxis and treatment is required in all moderate and major burns, specifically for early prophylaxis, perioperative prophylaxis, and clinical infection. Antimicrobial choice is based on specific patient or environmental bacteriological data.

    2014-01-01

    The purpose of this study was to investigate the frequency of enteral feeding intolerance in critically ill septic burn patients, the effect of enteral feeding intolerance on the efficacy of feeding, the correlation between the infection marker (procalcitonin [PCT]) and the nutrition status marker (prealbumin) and the impact of feeding intolerance on the outcome of septic burn patients. From January 2009 to December 2012 the data of all burn patients with the diagnosis of sepsis who were placed on enteral nutrition were analyzed. Septic patients were divided into two groups: group A, septic patients who developed feeding intolerance; group B, septic patients who did not develop feeding intolerance. Demographic and clinical characteristics of patients were analyzed and compared. The diagnosis of sepsis was applied to 29% of all patients. Of these patients 35% developed intolerance to enteral feeding throughout the septic period. A statistically significant increase in mean PCT level and a decrease in prealbumin level was observed during the sepsis period. Group A patients had statistically significant lower mean caloric intake, higher PCT:prealbumin ratio, higher pneumonia incidence, higher Sequential Organ Failure Assessment Maximum Score, a longer duration of mechanical ventilation, and a higher mortality rate in comparison with the septic patients without gastric feeding intolerance. The authors concluded that a high percentage of septic burn patients developed enteral feeding intolerance. Enteral feeding intolerance seems to have a negative impact on the patients' nutritional status, morbidity, and mortality.

  18. Burn injury and wound healing in X-linked ichthyosis.

    Yancon, Andrea R; Wahl, Wendy L

    2010-01-01

    X-linked ichthyosis is a skin condition of decreased keratin degradation and hyperkeratosis resulting from a deficiency of steroid sulfatase causing scaly skin. Burns in these patients may require skin grafting and harvesting from diseased donor sites. No descriptions of the outcomes of attempted grafting, donor site healing, and burn recovery in patients with X-linked ichthyosis exist. The authors describe split-thickness skin grafting in one patient with X-linked ichthyosis who sustained a burn with crush injury to his bilateral lower extremities. Although he developed cellulitis, there is no evidence that patients with ichthyosis have higher rates of infection. The patient exhibited rapid healing at postgrafting clinic visits with a much flatter texture than expected early after meshed skin grafting. This could be a benefit of the excess keratin state. Wound healing was not impaired by the ichthyosis. Concerns over skin harvest were alleviated by aggressive topical emollients, which did not negatively impact harvest of donor skin or primary burn site healing.

  20. Micronutrients after burn injury: a review.

    Science.gov (United States)

    Nordlund, Megan J; Pham, Tam N; Gibran, Nicole S

    2014-01-01

    Supplementation of micronutrients after burn injury is common practice in order to fight oxidative stress, support the immune system, and optimize wound healing. Assessing micronutrient status after burn injury is difficult because of hemodilution in the resuscitation phase, redistribution of nutrients from the serum to other organs, and decreases in carrier proteins such as albumin. Although there are many preclinical data, there are limited studies in burn patients. Promising research is being conducted on combinations of micronutrients, especially via the intravenous route.

    In the last two decades, much progress has been made in the control of burn wound infection and nasocomial infections (NI) in severely burned patients. The continiually changing epidemiology is partially related to greater understanding of and improved techniques for burn patient management as well as effective hospital infection control measures. With the advent of antimicrobial chemotherapeutic agents, infection of the wound site is now not as common as, for example, urinary and blood strea...

    Background: Burns are a major cause of death and disability worldwide. Today biological dressings have become an integral part of modern burn care. Using this method, in otherwise healthy young adults, the size of burn relative to the total body surface area (TBSA) correlating with a 50% mortality rate has increased from 30% to 80%. Due to a lack of experience and an interest in using biological dressings in Iran, as a developing country, the aim of this study was to compare patient outcome u...

    This study presents a 26-year epidemiological assessment of burn injury hospitalisations for people 15-29 years of age in Western Australia. Linked hospital morbidity and death data for all persons hospitalised with an index burn injury in Western Australia for the period 1983-2008 were analyzed. Annual age-specific incidence rates were estimated. Poisson regression analyses were used to estimate temporal trends in hospital admissions. There were 6404 burn hospital admissions of which 76% were male. Males had hospitalisation rates 3.0 times that of females (95%CI: 2.8-3.2) and Aboriginal people had rates 2.3 times (95%CI: 2.1-2.5) that of non-Aboriginal persons. Hospitalisations for burn injury declined by 42% (95%CI: 35-47) for males and 21% (95%CI: 6-33) for females. Hospitalisations declined by 53% (95%CI: 35-63) for Aboriginal people, and by 35% (95%CI: 29-41) for non-Aboriginal people. Significant reductions were observed for flame and electrical burn hospitalisations. The major causes of burns in males were exposure to controlled fires and ignition of inflammable materials, with scalds the predominant cause of burn in females. Downward trends in burn injury hospitalisations for both males and females 15-29 years of age were observed; however, males and Aboriginal persons have significantly elevated hospitalisation rates.

    1981-01-01

    Metabolic studies were performed on 23 burned children. They were studied sequentially until their burn wounds were healed. A metabolic study lasted 20 minutes, during which continuous measurements were made of O2 consumption and CO2 production rates, rectal temperature, average surface temperatures (dressings, skin and wound), body heat content, and rate of body weight loss using a bed scale. These measurements allowed solution of the heat balance equation for each study period. After 24 hours in a constant temperature room kept at 28 C and 40% relative humidity, metabolic studies were initiated when blood was drawn for catecholamine assay, followed by a metabolic analysis, after which dressings were removed and fresh silvadene applied to the wounds. No dressings were applied. Metabolic analyses were repeated after two and four hours of exposure, after which blood for catecholamine analysis was drawn and the study terminated. Without dressings in a thermally neutral environment, burn patients demonstrated an increased rate of heat loss of 27 watts/square meter body surface area (W/M2), compared with the predicted normal. The major portion of this increment is by evaporation, which increased 300%. The rate of heat production equals heat loss, and is increased 50% above the predicted normal. Occlusive dressings result in a 15 W/M2 decrease in the rate of heat loss, about evenly divided between evaporative and dry routes, with a corresponding 15 W/M2 decrease in the rate of heat production. Plasma catecholamine levels of bandaged burn patients are not significantly different from values for healed burn patients, and do not correlate with the rate of heat production. The increased heat production of burn patients is a response to an increased rate of heat loss, not vice versa. The use of occlusive dressings substantially reduces the energy requirements to manageable levels, even in patients with very large burns. PMID:7235763

    Spectral hole burning is investigated in an optical medium in the presence of Doppler broadening and Kerr nonlinearity. The Kerr nonlinearity generates coherent hole burning in the absorption spectrum. The higher order Kerr nonlinearity enhances the typical lamb dip of the hole. Normal dispersion in the hole burning region while Steep anomalous dispersion between the two hole burning regions also enhances with higher order Kerr effect. A large phase shift creates large delay or advancement in the pulse propagation while no distortion is observed in the pulse. These results provide significant steps to improve optical memory, telecom devices, preservation of information and image quality. Supported by Higher Education Commission (HEC) of Pakistan

    Tumors that develop in old burn scars are usually squamous cell carcinomas. Sarcomas have also been reported, albeit rarely. To our knowledge, there has been only one case report of an extraskeletal osteosarcoma arising in a prior burn scar reported in the English-language literature, mainly discussing the clinicopathological features. Herein, we present a case of cutaneous osteosarcoma visualized as a mineralized soft-tissue mass arising from the scar associated with a previous skin burn over the back. This seems to be the first report describing the imaging features of a cutaneous osteosarcoma from an old burn scar. (orig.)

  11. Deciding Where to Burn: Stakeholder Priorities for Prescribed Burning of a Fire-Dependent Ecosystem

    Full Text Available Multiagency partnerships increasingly work cooperatively to plan and implement fire management. The stakeholders that comprise such partnerships differ in their perceptions of the benefits and risks of fire use or nonuse. These differences inform how different stakeholders prioritize sites for burning, constrain prescribed burning, and how they rationalize these priorities and constraints. Using a survey of individuals involved in the planning and implementation of prescribed fire in the Onslow Bight region of North Carolina, we examined how the constraints and priorities for burning in the longleaf pine (Pinus palustris ecosystem differed among three stakeholder groups: prescribed burn practitioners from agencies, practitioners from private companies, and nonpractitioners. Stakeholder groups did not differ in their perceptions of constraints to burning, and development near potentially burned sites was the most important constraint identified. The top criteria used by stakeholders to decide where to burn were the time since a site was last burned, and a site's ecosystem health, with preference given to recently burned sites in good health. Differences among stakeholder groups almost always pertained to perceptions of the nonecological impacts of burning. Prescribed burning priorities of the two groups of practitioners, and particularly practitioners from private companies, tended to be most influenced by nonecological impacts, especially through deprioritization of sites that have not been burned recently or are in the wildland-urban interface (WUI. Our results highlight the difficulty of burning these sites, despite widespread laws in the southeast U.S. that limit liability of prescribed burn practitioners. To avoid ecosystem degradation on sites that are challenging to burn, particularly those in the WUI, conservation partnerships can facilitate demonstration projects involving public and private burn practitioners on those sites.

    2017-11-20

    Objective: To investigate the effects of hydrogen on the lung damage of mice at early stage of severe burn. Methods: One hundred and sixty ICR mice were divided into sham injury, hydrogen, pure burn, and burn+ hydrogen groups according to the random number table, with 40 mice in each group. Mice in pure burn group and burn+ hydrogen group were inflicted with 40% total body surface area full-thickness scald (hereafter referred to as burn) on the back, while mice in sham injury group and hydrogen group were sham injured. Mice in hydrogen group and burn+ hydrogen group inhaled 2% hydrogen for 1 h at post injury hour (PIH) 1 and 6, respectively, while mice in sham injury group and pure burn group inhaled air for 1 h. At PIH 24, lung tissue of six mice in each group was harvested, and then pathological changes of lung tissue were observed by HE staining and the lung tissue injury pathological score was calculated. Inferior vena cava blood and lung tissue of other eight mice in each group were obtained, and then content of high mobility group box 1 (HMGB1) and interleukin-6 (IL-6) in serum and lung tissue was determined by enzyme-linked immunosorbent assay. Activity of superoxide dismutase (SOD) in serum and lung tissue was detected by spectrophotometry. After arterial blood of other six mice in each group was collected for detection of arterial partial pressure of oxygen (PaO(2)), the wet and dry weight of lung tissue were weighted to calculate lung wet to dry weight ratio. The survival rates of the other twenty mice in each group during post injury days 7 were calculated. Data were processed with one-way analysis of variance, LSD test and log-rank test. Results: (1) At PIH 24, lung tissue of mice in sham injury group and hydrogen group showed no abnormality. Mice in pure burn group were with pulmonary interstitial edema, serious rupture of alveolar capillary wall, and infiltration of a large number of inflammatory cells. Mice in burn+ hydrogen group were with mild

  18. Burning mouth syndrome: Clinical dilemma?

    Full Text Available Burning Mouth Syndrome (BMS is a chronic orofacial burning pain condition usually in the absence of clinical and laboratory findings that affects many adults worldwide, yet its etiology and treatment remain poorly understood. Though it has been associated with numerous oral and systemic conditions, there has been no clear consensus on its etiology, pathogenesis and treatment. As a result, patients with inexplicable oral complaints are often referred from one health care professional to another without effective management having significant emotional impact on patients. As the dental profession expands its scope of care to oral medicine and geriatrics, BMS will be more effectively diagnosed and managed by these dental surgeons. Hence, they should be more involved in evaluation and management of these patients. The present article provides updated information on BMS including possible etiological factors and current treatment options, although data on the effectiveness of these treatment modalities remain limited. Recently researchers found that treatment with a familiar nutritional supplement- lipoic acid- is of remarkable benefit with minimal adverse effects. ALA (alpha-lipoic acid may be the effective treatment modality in management of BMS.

    NLRP3 inflammasome activation is recently reported to be linked to the pathogenesis of sepsis. Artemisinin is shown to play beneficial effects in sepsis. However, the impacts of artemisinin on burn sepsis have not been investigated. This study is designed to investigate the role of artemisinin in burn sepsis and the involvement of NLRP3 inflammasome activation. Male BALB/c mice were randomly divided into sham burn, burn, burn sepsis, and artemisinin treated groups. Inflammatory cytokines were measured by enzyme-linked immunosorbent assay. Adhesion molecules and neutrophil infiltration in lung and heart were detected by real-time polymerase chain reaction. Mortality rates were monitored. Artemisinin was added to Raw 264.7 cells that were stimulated with burn sepsis serum in the presence/absence of an inhibitor of NLRP3 inflammasome, 3, 4-methylenedioxy-β-nitrostyrene. Interleukin (IL) 1β and IL-18 messenger RNA expression as well as NLRP3 and caspase 1 protein were measured. Production of inflammatory cytokines in serum, levels of adhesion molecules and neutrophil infiltration in lung and heart, and mortality rate of burn septic mice were significantly higher than those of control. These effects were attenuated by artemisinin. Artemisinin down-regulated protein levels of NLRP3 and caspase 1 and inhibited the increases of IL-1β and IL-18 messenger RNA expression from Raw 264.7 cells that were stimulated with burn sepsis serum. These effects of artemisinin were not further strengthened in the presence of 4-methylenedioxy-β-nitrostyrene. Artemisinin protects mice from burn sepsis by attenuating the inflammatory response and alleviating inflammatory infiltration in vital organs, likely through inhibiting the activation of NLRP3 inflammasome.

    The survival of recently fallen northern red oak acorns after exposure to a cool fall burn was evaluated in northwestern Pennsylvania. Although no acorns were consumed by the fire, some were charred. Between 40 and 49 percent of the acorns in the litter were destroyed. The fire was not hot enough to kill Curculio larvae within the acorns. Burned acorns infested with Curculio that survived the fire had 20 percent lower germination rates than unburned acorns.

  2. National programme for prevention of burn injuries

    Directory of Open Access Journals (Sweden)

    Gupta J

    2010-10-01

    Full Text Available The estimated annual burn incidence in India is approximately 6-7 million per year. The high incidence is attributed to illiteracy, poverty and low level safety consciousness in the population. The situation becomes further grim due to the absence of organized burn care at primary and secondary health care level. But the silver lining is that 90% of burn injuries are preventable. An initiative at national level is need of the hour to reduce incidence so as to galvanize the available resources for more effective and standardized treatment delivery. The National Programme for Prevention of Burn Injuries is the endeavor in this line. The goal of National programme for prevention of burn injuries (NPPBI would be to ensure prevention and capacity building of infrastructure and manpower at all levels of health care delivery system in order to reduce incidence, provide timely and adequate treatment to burn patients to reduce mortality, complications and provide effective rehabilitation to the survivors. Another objective of the programme will be to establish a central burn registry. The programme will be launched in the current Five Year Plan in Medical colleges and their adjoining district hospitals in few states. Subsequently, in the next five year plan it will be rolled out in all the medical colleges and districts hospitals of the country so that burn care is provided as close to the site of accident as possible and patients need not to travel to big cities for burn care. The programme would essentially have three components i.e. Preventive programme, Burn injury management programme and Burn injury rehabilitation programme.

  3. Management of Critical Burn Injuries: Recent Developments

    Directory of Open Access Journals (Sweden)

    David J. Dries

    2017-02-01

    Full Text Available Background Burn injury and its subsequent multisystem effects are commonly encountered by acute care practitioners. Resuscitation is the major component of initial burn care and must be managed to restore and preserve vital organ function. Later complications of burn injury are dominated by infection. Burn centers are often called to manage problems related to thermal injury, including lightning and electrical injuries. Methods A selected review is provided of key management concepts as well as of recent reports published by the American Burn Association. Results The burn-injured patient is easily and frequently over resuscitated, with ensuing complications that include delayed wound healing and respiratory compromise. A feedback protocol designed to limit the occurrence of excessive resuscitation has been proposed, but no new “gold standard” for resuscitation has replaced the venerated Parkland formula. While new medical therapies have been proposed for patients sustaining inhalation injury, a paradigm-shifting standard of medical therapy has not emerged. Renal failure as a specific contributor to adverse outcome in burns has been reinforced by recent data. Of special problems addressed in burn centers, electrical injuries pose multisystem physiologic challenges and do not fit typical scoring systems. Conclusion Recent reports emphasize the dangers of over resuscitation in the setting of burn injury. No new medical therapy for inhalation injury has been generally adopted, but new standards for description of burn-related infections have been presented. The value of the burn center in care of the problems of electrical exposure, both manmade and natural, is demonstrated in recent reports.

  4. Survey on current hydrotherapy use among North American burn centers.

    2010-01-01

    The authors have reviewed hydrotherapy practices in North American burn centers and described the epidemiology of hydrotherapy-associated nosocomial infections. A web-based survey was distributed to the directors of all burn care facilities listed by the American Burn Association. Questions addressed aspects of practice, including the method, additives, disposable liners, decontamination practices, nosocomial pathogens, and perceptions regarding the "ideal" method of hydrotherapy. The response rate was 44%, 59 of 142 centers, or 827 of 1900 beds. Hydrotherapy is regularly used by 83% of centers. Among these centers, 10% use exclusively immersion hydrotherapy (IH), 54% use exclusively shower cart hydrotherapy (SCH), and 35% use a combination of IH and SCH. Disposable liners are used at 80% of centers. Tap water alone is used by 51% of centers, 27% add detergent, 16% chlorhexidine, and 7% povidone-iodine. The majority of centers (57%) do not routinely culture their hydrotherapy equipment, 20% culture weekly, 7% monthly, and 17% less than once per month. Directors believe that Pseudomonas aeruginosa, methicillin-sensitive Staphylococcus aureus, and methicillin-resistant S. aureus are the most common nosocomial pathogens, followed by Acinetobacter species and Candida albicans. The relative frequency of occurrence of the first three pathogens did not vary with regard to the hydrotherapy method used. Given the opportunity to redesign, 45% of burn unit directors would implement SCH only, 42% a combination of SCH and IH, 2% exclusively IH, and 11% no hydrotherapy or bedside irrigation only. The prevalence of hydrotherapy use at North American burn centers has decreased since 1990 (83% vs 95%), yet continues to be used at the majority of centers. The use of IH has also declined (55% vs 81%). The trend away from the exclusive use of IH will likely continue, because more centers incorporate showering methods.

    To evaluate quantitatively confinement capability of the radioactive materials in the nuclear fuel facility under the fire accident, analysis of accident sequence, including clogging characteristics of the ventilation filters, needs to be performed. For the purpose of the evaluation, accumulation of the source term data such as release rates of the smoke and energy, and particle size distribution of the smoke during the fire accident is necessary. Therefore, experiments for evaluating burning characteristics of combustible solid wastes and recovered solvents, which are disposed from the facilities, have been performed by using the mock combustible wastes and the method for estimating the source terms has been investigated. When mixtures of rubber and cloth gloves as mock combustible solid wastes were burnt, the smoke with above 1 {mu}m in diameter was confined in the carbonized residue of cloth gloves and the release ratio of the smoke in the burning of mixtures was decreased compared with the burning of only rubber gloves. The source terms were evaluated with the cell ventilation system safety analysis code CELVA-1D by using the experimental results as the input, such as temperature of the gas phase, total burnt weight and total collected weight of the smoke under the burning of rubber gloves as mock wastes. The source terms calculated by the CELVA-1D reasonably agreed with the values estimated from the recommended calculation parameters in the Nuclear Fuel Cycle Facility Accident Analysis Handbook (NUREG-1320). Therefore, the present CELVA-1D method for evaluating the source terms during burning is considered to be valid. This means that the source terms can be estimated by using this method if the information such as the temperature of the gas phase, total burnt weight and total collected weight of the smoke are given.

    1999-09-01

    To better master the use of ciprofloxacin (CPF) in burn patients, a clinical study, including pharmacokinetics in serum and urine, was undertaken in a pathophysiologically homogeneous population of major-burn subjects. Twelve major-burn patients who were infected with Pseudomonas aeruginosa, enterobacteria and gram-positive cocci, received CPF (600 mg t.i.d.). The mean body surface area affected by third-degree burns was 31.8 +/- 14.5%. Two series of blood samples were drawn after the first and seventh doses; urine was collected during the first infusion. Levels of CPF in serum and urine were measured by means of high-performance liquid chromatography. A non-compartmental method was used for kinetic and graphic analysis of concentration-time pairs. No adverse effects were noted. Trough concentrations measured on day 3 (mean +/- SD) were above the minimum inhibitory concentration (MIC) for the organism responsible for infection; i.e., 2.0 +/- 1.2 microg. ml(-1), and maximum concentrations were high 9. 9 +/- 3.4 microg. ml(-1). An area under the concentration-time curve (AUC)/MIC ratio above 125 SIT(-1) (where SIT is the serum inhibitory titer), which has been strongly correlated with clinical response and time to bacterial eradication, was achieved in 11 patients with a MIC of 0.5 microg. ml(-1). There was a statistically significant difference between C(min) and AUC determined on day 1 and day 3. In contrast to healthy volunteers, CPF clearance rates were notably decreased. The pharmacokinetics of CPF was altered in major-burn patients. The recommended dosage regimen for administration of CPF, i.e. 600 mg t.i.d. shows no adverse effects and a good microbiological efficacy.

    were taken in concentric circles around the burned trees at two soil depths. We complemented this investigation by conducting a series of laboratory simulations. Non-burned soil was taken for laboratory analysis and rainfall simulations. Four treatment types were conducted: non-burned soil, non-burned soil + pine needles, burned soil without ash (300°C/15 min. after adding pine needles) and burned soil with the residue ash (300°C/15 min. after adding pine needles). Hydrophobicity was measured in all trays. Constant rainfall intensity of 30 mm/hr was simulated until terminal infiltration rates were reached. The experimental trays were oven dried and simulated again to imitate the effect of second rainstorm. Preliminary results indicate strong surface WR (60% >180s) at a distance of 1m and at the subsurface (50% >180s) directly by the trunk. In the control non-burned site stronger WR was found in proximity to the trunks. While in the burned sites extreme values (>300s) were apparent (15-35%) and correlated with distance from the trunk, no corresponding patterns were noticed in the control trees. The attempt to create homogeneous layer of WR under controlled laboratory conditions yielded a scattered pattern of repellency, similar to the field conditions. In contrast to expected, the bare soil and bare soil covered by needles exhibited the highest and lowest infiltration rates, respectively, while the burned hydrophobic soils demonstrated intermediate rates. It is thus suggested that in some soils, WR might enhance infiltration capacity by creating a complex mosaic of runoff-generating and runoff-absorbing micro-patches. In the experimental non-burned soil a rapid crusting of the surface provided lateral connectivity whilst the accumulation of litter and organic matter blanket the surface and enhance the vertical conductivity. To better understand the role of WR in generating hydrological response, it is required to consider the 3D 'sponge like' properties of the WR

    Accreting neutron stars exhibit Type I X-ray bursts from both frequent hydrogen/helium flashes as well as rare carbon flashes. The latter (superbursts) ignite in the ashes of the former. Hydrogen/helium bursts, however, are thought to produce insufficient carbon to power superbursts. Stable burning could create the required carbon, but this was predicted to only occur at much larger accretion rates than where superbursts are observed. We present models of a new steady-state regime of stable hydrogen and helium burning that produces pure carbon ashes. Hot CNO burning of hydrogen heats the neutron star envelope and causes helium to burn before the conditions of a helium flash are reached. This takes place when the mass accretion rate is around 10 per cent of the Eddington limit: close to the rate where most superbursts occur. We find that increased heating at the base of the envelope sustains steady-state burning by steepening the temperature profile, which increases the amount of helium that burns before a runaway can ensue.

    Severe burns result in a hypermetabolic state that is associated with increased morbidity and mortality. We reviewed the literature to determine if there is strong evidence that short-term β-blockers reduce the hypermetabolic state or mortality and length of stay (LOS) compared with no therapy in patients with severe burns. A literature search of PubMed, Embase, the Cochrane Database of Systematic Reviews, and BestBETs was conducted on the use of adrenergic β-antagonists in burn patients. Six randomized controlled trials met the inclusion criteria. Five pediatric trials found that β-blockers reduced the hypermetabolic state (as defined by reduction of cardiac work, rate pressure product, resting energy expenditure, central deposition of fat, and bone mineral loss) and were associated with an improvement in lean muscle mass in patients with severe burns. However, there was no change in LOS or mortality in these children. One adult study in burn patients found shorter LOS in patients treated with β-blockers but no difference in mortality rate. β-blockers were relatively well tolerated, with no differences in adverse effects reported. β-blockers seem to reduce the hypermetabolic state in pediatric patients with burns, but there is insufficient evidence to suggest they have an impact on mortality rates or LOS.

    Patients burned intentionally experience extensive injuries with high rates of morbidity and mortality. Nonetheless, there is no consensus if these patients have worse outcomes than unintentional burns considering injury severity and other preexistent comorbidities. We conducted a ten-year retrospective review on all patients treated at the Burn Unit of Hospital de Pronto Socorro, Porto Alegre, Brazil, between 2003 and 2012. The aim was to compare survival of self-inflicted burns and burns from assaults with unintentional injuries using a Multivariable Cox Regression Analysis. 1734 patients were included in the study, 87.7% non-intentional, 6.6% self-inflicted and 5.8% from aggression. Intentional injuries resulted in more severe injuries and were associated with psychiatric disorders and drug abuse. After controlling for injury severity, previous clinical comorbidities and previous psychiatric disorders, only self-inflicted burns correlated significantly with a higher risk of death (HR=1.59, CI 95% 1.05-2.41, p=0.03). Self-inflicted injuries were independently associated with a higher risk of death. Burns from aggression were not associated with higher mortality in this model. Prevention of these injuries must be priority and treating the main associated factors such as drug abuse and psychiatric disorders may lower its occurrence. Copyright © 2014 Elsevier Ltd and ISBI.

  12. Continuous Arteriovenous Hemodialysis and Continuous Venovenous Hemofiltration in Burn Patients with Acute Renal Failure

    Full Text Available Acute renal failure (ARF is a very common condition that may occur in patients with major burn injuries. The majority of burn patients with ARF have a high mortality rate, ranging from 73% to 100%. There are several ways to treat ARF in burn patients, including peritoneal dialysis (PD, intermittent hemodialysis, and continuous renal replacement therapy (CRRT. CRRT is generally used in patients in whom intermittent hemodialysis has failed to control hypovolemia, as well as in patients who cannot tolerate intermittent hemodialysis. Additionally, PD is not suitable for patients with burns within the abdominal area. For these reasons, most patients with unstable hemodynamic conditions receive CRRT. In this study (conducted in our burn unit between 1997 and 2004, six burn patients received CRRT: three received continuous arteriovenous hemodialysis (CAVHD and the other three received continuous venovenous hemofiltration (CVVH. The patients were all males, with a mean age of 49.8 years (range, 27–80 years, and a mean burnt surface area of 65.1% (range, 30–95%. Four patients died due to multiple organ failure, and two patients recovered from severe ARF. CRRT has been proven safe and useful for burn patients with ARF. According to this study, we conclude that CVVH is an appropriate tool for treating ARF, with a lower incidence of vascular complications than CAVHD.

    Full Text Available Many of peoples are faced minor or major burn injuries in their life. Even the most widespread burn cause is flame injuries, too different burn cause pointed out in literature like Acetylen burns. The cases which imply in literature, mostly causes from explosion of high pressure acetylene tube, metal oxygene patch flame or carbide lamp using from cave explorers. An interesting acetylene burn cause in Turkey was publised by the authors. This cases was to come into being from flying toy balloons flame. 80 person was injured from flying toy ballons flame in a meeting in 2002. Although this potential risks of acetylene, helium have not any of some risk. But helium was provided from other countries and have more price. The injuries which caused from acetylene burns like 1st -2nd degree burns. Consequently that was known helium is more avaliable for using in toy sector, and never cause burn injuries like this.

    Over the last decades advancements have improved survival and outcomes of severely burned patients except one population, elderly. The Lethal Dose 50 (LD50) burn size in elderly has remained the same over the past three decades, and so has morbidity and mortality, despite the increased demand for elderly burn care. The objective of this study is to gain insights on why elderly burn patients have had such a poor outcome when compared to adult burn patients. The significance of this project is that to this date, burn care providers recognize the extreme poor outcome of elderly, but the reason remains unclear. In this prospective translational trial, we have determined clinical, metabolic, inflammatory, immune, and skin healing aspects. We found that elderly have a profound increased mortality, more premorbid conditions, and stay at the hospital for longer, p elderly, p > 0.05, but a significant increased incidence of multi organ failure, p elderly have substantially different responses to burns when compared to adults associated with increased morbidity and mortality. This study indicates that these responses are complex and not linear, requiring a multi-modal approach to improve the outcome of severely burned elderly. PMID:26629550

    Full Text Available Abstract: In the last century, advances in medical care and longevity have resulting in an increase in the elderly population, and the world and Turkey populations have become older. In parallel with the aging population, problems seen in old people have been increasing. Burn, one of these problems, causes more serious injuries and high level of mortality in people aged 65 years and over compared to the general population. Reduction in sensory/cognitive functions, slowing reflexes, limited movements and accompanying situations (chronic diseases, alcoholism, used medication, neurological and psychiatric disorders which are due to physiology of elderly people increase the burn incidence and the severity of burn. In addition, these factors could also raise the ventilation requirement, complications and hospitalization period in burnt patients. Despite the recent developmetns in burn treatment and care, burn is still a serious health problem for elderly people. As the majority of the burn injuries are preventable, the essential point of burn administration in elderly people should be related to the prevention of burn incidence.

    Thrombocytopenia is initially seen in patients with burn injury as a transient occurrence during the first week after injury. Subsequent decreases occur later in the course of treatment and are commonly due to sepsis, dilutional effects, and medication exposure. Although studies have demonstrated that thrombocytopenia in the critically ill patients is associated with a worse prognosis, there is limited literature as to the significance of thrombocytopenia in the pediatric burn patients. In this study, the authors evaluate the prognostic implications of thrombocytopenia in the pediatric burn patients. They performed a 5-year retrospective chart of patients aged 18 years or younger with burns >20% TBSA admitted to their institution. Data collected included patient demographics, burn etiology and %TBSA involvement, length of stay, pertinent laboratory values, and in-hospital morbidity and mortality. Of the 187 patients studied, thrombocytopenia occurred in 112 patients. Eighty-two percent demonstrated thrombocytopenia within the first week of injury and 18% demonstrated additional episodes of thrombocytopenia after this time. A reactive thrombocytosis occurred in 130 (70%) patients. The incidence of thrombocytopenia could not be attributed to age, gender, or burn etiology. However, patients with thrombocytopenia were more likely to have inhalation injury and extensive TBSA involvement than those without (P thrombocytosis in the pediatric burn patient is associated with increased mortality risk and is influenced by the extent of burn, inhalation injury, and the development of sepsis.

    Paediatric burns make up a significant proportion of burn injured patients seen within the hospital setting and worldwide account for a significant proportion of unintentional deaths. Currently there is limited data on severe paediatric burns requiring intensive care support. Our study aimed primarily to describe the epidemiology of severe burns admitted to the intensive care unit at our centre receiving fluid resuscitation over a 10 year period. A secondary aim was to describe the referrals patterns in general over the same time period. A retrospective analysis was performed for paediatric patients referred to our centre receiving fluid resuscitation and intensive care support from 2003 to 2013. We also analysed the patterns of referrals, admissions and need for surgical intervention over the same time period retrospectively. Children less than 5 years old made up 65% of admissions to intensive care and scald injuries (56%) were the commonest aetiology. Both total length of stay (25 days in 2003 to 10 days in 2013) and intensive care length of stay (7.2 days in 2003 to 3 days in 2013) decreased during the study and less patients underwent operative intervention. Referrals to our centre increased from 261 in 2003 to 366 in 2013, however admission rates declined from 145 to 85 during that time period. Currently there is limited data on severe burns within the paediatric population. Our study provides epidemiological data in this area, an important step for developing future prevention strategies.

    Full Text Available Pseudomonas aeruginosa is an important life-threatening nosocomial pathogen and plays a prominent role in serious infections in burned patients. The current study was undertaken to characterize P. aeruginosa strains isolated from burned patients in Tehran, Iran. The study was conducted in a major burn center in Tehran, Iran in 2007. A total of seventy specimens obtained from different clinical origin with positive culture results for P. aeruginosa were included in the study. Antimicrobial susceptibility test was performed according to the standard CLSI guideline. The relationship between the strains was also determined using antimicrobial drug resistance pattern analysis and plasmid profiling. All strains were multi drug resistant. The percentage of resistance to tested antibiotics was: imipenem 97.5%, amikacin 90%, piperacillin 87.5%, ceftizoxime 72.7%, gentamicin 67.5%, ciprofloxacin 65%, ceftriaxone 60%, and ceftazidime 57.5%. Thirteen resistant phenotypes were recognized, R3 (TET, IPM, AMK, CIP, PIP, GM, CAZ, CRO, CT was the predominant resistance pattern seen in 27.5% of isolates. Results obtained from E-test showed that 100% of P. aeruginosa strains were resistant to cefoxitin, 97% to cefotetan, 93% to ticarcillin, 89% to ticarcillin/clav, 76% to gentamicin and imipenem, 63% to piperacillin, 49% to tetracycline, and 20% to meropenem. Nine different plasmid profiles were observed among the strains. The current study showed an increase rate of resistance for some antibiotics tested among P. aeruginosa strains isolated from burned patients in Tehran. A combination of antibiotic susceptibility testing and profile plasmid analysis, which are relatively cheap and available methods, showed to be useful to characterize the clinical strains of P. aeruginosa isolated from burned patients in Iran.

    Diabetic burns patients may be at risk of worse clinical outcomes. This study aims to further investigate the impact of diabetes mellitus on clinical outcomes in burns patients in Singapore. A 3-year retrospective review was performed at the Singapore General Hospital Burns Centre (2011-2013). Pure inhalational burns were excluded. Diabetic (N=53) and non-diabetic (N=533) patients were compared, and the impact of diabetes on clinical outcomes, adjusting for confounders, was investigated using multivariate logistic regression. The diabetic group had a significantly higher incidence of wound infection and severe renal impairment, as well as a longer length of stay, higher number of operations and higher rate of unplanned readmission. ICU admission was significantly associated with hyperglycaemia (OR 5.44 [2.61-11.35], p<0.001) and a higher total body surface area of burn (OR per 1% TBSA 1.07 [1.05-1.09], p<0.001). Unplanned readmission was significantly associated with wound infection (OR 4.29 [1.70-10.83], p=0.002), and mortality associated with a higher TBSA (OR per 1% TBSA 1.1 [1.07-1.14], p<0.001). After adjusting for confounders, diabetes mellitus was not significantly associated with unplanned readmission or mortality. Diabetic burns patients have an increased risk of worse clinical outcomes, including wound infections, renal impairment and longer length of stay. Copyright © 2016 Elsevier Ltd and ISBI.

    There is a growing volume of data that indicates that serious injury suppresses immune function, predisposing individuals to infectious complications. With recent evidence showing long-term immune dysfunction after less severe burn, this study aimed to investigate post-burn infectious disease morbidity and assess if burn patients have increased long-term hospital use for infectious diseases. A population-based longitudinal study using linked hospital morbidity and death data from Western Australia for all persons hospitalised for a first burn (n=30,997) in 1980-2012. A frequency matched non-injury comparison cohort was randomly selected from Western Australia's birth registrations and electoral roll (n=123,399). Direct standardisation was used to assess temporal trends in infectious disease admissions. Crude annual admission rates and length of stay for infectious diseases were calculated. Multivariate negative binomial and Cox proportional hazards regression modeling were used to generate adjusted incidence rate ratios (IRR) and hazard ratios (HR), respectively. After adjustment for demographic factors and pre-existing health status, the burn cohort had twice (IRR, 95% confidence interval (CI): 2.04, 1.98-2.22) as many admissions and 3.5 times the number of days in hospital (IRR, 95%CI: 3.46, 3.05-3.92) than the uninjured cohort for infectious diseases. Higher rates of infectious disease admissions were found for severe (IRR, 95%CI: 2.37, 1.89-2.97) and minor burns (IRR, 95%CI: 2.22, 2.11-2.33). Burns were associated with significantly increased incident admissions: 0-30days (HR, 95%CI: 5.18, 4.15-6.48); 30days-1year (HR, 95%CI: 1.69, 1.53-1.87); 1-10 years (HR, 95%CI: 1.40:1.33-1.47); >10years (HR, 95%CI: 1.16, 1.08-1.24). Respiratory, skin and soft tissue and gastrointestinal infections were the most common. The burn cohort had a 1.75 (95%CI: 1.37-2.25) times greater rate of mortality caused by infectious diseases during the 5-year period after discharge than

    Sexual function is a profound facet of the human personality. Burns due their sudden and devastating nature can have longstanding effects on intimate function by virtue of physical sequelae as well as alterations in body image and perceived desirability. A considerable number of patients encounter problems with intimate function in burns rehabilitation; nevertheless, the topic appears to be poorly addressed in specialist centers worldwide. Review of the literature suggests that a number of parameters can affect the quality of sexual life following burn injuries including age at the time of injury, location, and severity of the burn as well as coping mechanisms employed by the individual survivor. Addressing issues of intimacy relies on awareness, education, and a holistic approach on behalf of the multidisciplinary team members and, to this effect, recommendations are made on managing sexual function concerns in burns rehabilitation.
