    Chemical burns are less frequent in routine practice, but could be very serious owing to the complexity and severity of their actions. Influx of casualty after a civil disaster (industrial explosion) or military (war or terrorism) is possible. The action of these agents could be prolonged and deep. In addition to the skin, respiratory lesions and general intoxication could be observed. The urgent local treatment rely essentially on prolonged washing. Prevention and adequate emergency care could limit the serious consequences of these accidents. Accidents (thermal burns or electrisations) due to high or low voltage electricity are frequent. The severity is linked with the affected skin but especially with internal lesions, muscular, neurological or cardiac lesions. All cases of electrisation need hospital care. Locally, the lesions are often deep with difficult surgical repairs and often require amputation. Aesthetic and functional sequela are therefore frequent. Secondary complications could appear several months after the accident: cataract, dysesthesia and hypotonia. PMID:12621941

    Full Text Available A 35-year-old male farmer came in contact with 11,000 volts high tension electric wire and sustained full thickness burn wounds over scapula, upper limb and anterior abdominal wall along with perforation of the intestine. Patient was initially managed conservatively in general surgery ward and was referred to us after 3 days with necrosis of the burned skin and muscles over the shoulder and abdomen. Patient was initially managed conservatively and then thorough debridement of the necrotic skin over the left shoulder and upper arm was done and the area was split skin grafted. Patient developed enterocutaneous fistula, which healed over a period of 8 weeks. The granulating wound over the abdomen was also skin grafted and patient was discharged after 18 days. About 4 months, after the discharge patient presented with ventral hernia. Repair of ventral hernia by synthetic mesh application and reconstruction of the abdominal wall with a free tensor fascia lata flap was done over the mesh, but the flap failed. Then after debridement two random pattern transposition skin flaps, one from the right upper and another from the left lower abdomen were transposed over the abdominal wound and donor area was skin grafted. Patient was discharged after 17 days.

    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.

    Electrical burns caused by low-voltage batteries are rarely reported. We recently encountered a male patient who suffered from a superficial second-degree burn over his left elbow and back. The total body surface area of the burn was estimated to be 6%. After interviewing the patient, the cause was suspected to be related to the explosion of a music player on the left-side of his waist, carried on his belt while he was painting a bathroom wall. Elevated creatine kinase levels and hematuria indicated rhabdomyolysis and suggested an electrical burn. Initial treatment was done in the burn intensive care unit with fluid challenge and wound care. The creatine kinase level decreased gradually and the hematuria was gone after 4 days in the intensive care unit. He was then transferred to the general ward for further wound management and discharged from our burn center after a total of 11 days without surgical intervention. PMID:25678181

    Electrical burns are among the most devastating types of burns, with wide-ranging injuries. They can sometimes occur in the context of fishing, usually involving high voltages. The authors present the case of a 59-year-old-man who suffered a sports accident during a fishing competition, with the formation of an electrical arc due to proximity of the fishing rod and high voltage cables. He presented burns affecting 3% of TBSA, third degree deep burns on trunk and left hand; no signs of cardiac injury. He was admitted to our Burn Unit for monitoring, care dressing and surgical treatment; complete wound healing was achieved after 24 days. Due to its relatively small share among burns, published data on electrical injuries and fishing remain scarce, and differ in patient collectives due to infrastructural or environmental differences. The authors are not aware of published specific reports on electrical burns in sports fishing practice, like the case here presented. The authors want to alert for potential medical, social and economic consequences of this type of sports accidents that could be entirely avoidable with some preventive measures. PMID:24704363

    Bone scan is known to be an effective tool for observing the state of soft tissues and bones of electric burn patients. It is also used for observing the progress of patients after debridement or skin graft as well as determining to amputate specific body parts. To evaluate bone scan's role in electric burn, we analyzed bone scan 37 patients with electric burn. Among the 37 patients, 8 of 37 were injured in low voltage and 29 of them in high voltage. 27 patients received the electrical input through the hand, 6 through the scalp, 2 through the shoulder, 1 through the left chest wall and 1 through the left inguinal area. Among 29 patients received high voltage, 22 patients had the electrical output through the foot, 3 through the hand, 2 through the shoulder, 1 through the buttock and 1 through the left chest wall. Bone scans revealed cellulitis in 37 patients with 47 sites, osteomyelitis in 15 patients with 15 sites and bone defects in 4 patients with 4 sites. In 4 patients with skin graft or skin flap, follow up bone scan showed improvements of bony uptake in preoperatively bony defect area and all of them were healed without complication There were 2 cases in which uptake increased in the myocardium, 1 in the liver and 6 in the kidney, however, scrum calcium level, EKG, cardiac enzyme, liver and renal function tests were normal. In conclusion, bone scans are helpful in the assessment of injury sites after electrical insult and in differential diagnosis of cellulitis and osteomyelitis. It is also useful tool of assessment after skin graft or skin flap, however, it should be further evaluated about internal organ damage.

    Full Text Available Electrical injuries due to high-tension voltage (>1000 volts cause destruction at the point of contact with massive necrosis of deeper structures such as muscles, vessels and nerves. Rhabdomyolysis due to massive breakdown of skeletal muscles may lead to acute renal failure secondary to myoglobinuria. The study was undertaken to observe the correlation of renal complications with extent and progression of tissue damage in high-tension voltage electrical burns. Renal biochemical parameters as predictors of acute renal failure were also studied. Thirty two patients of high tension voltage electrical burn injuries presenting during one year period 1-1-2001 to 31-12-2001 were studied. Low-tension voltage electrical injuries (< 1000 volts mimic thermal burns were excluded from the study. The electrical wound assessment and the renal biochemical parameters were done daily for the first seven days and then on alternate days for another seven days. Assessment of progression of wounds and correlation with the renal biochemical parameters was done. Patients who died following electrical burns were subjected to autopsy and histopathological examination of both kidneys. Out of the thirty-two patients, six (18.75% went into acute renal failure. Five out of these six patients died because of renal failure (mortality rate 83.33%. There was definite progression of electric burn wounds. There was no correlation between progression of electrical burn wounds and acute renal failure. Serum creatinine was found to be the most important biochemical parameter as a prognostic indicator of acute renal failure.

    Full Text Available In this work, the effects of the electric fields on the flame propagation and combustion characteristics of lean premixed methane–air mixtures were experimentally investigated in a constant volume chamber. Results show that the flame front is remarkably stretched by the applied electric field, the stretched flame propagation velocity and the average flame propagation velocity are all accelerated significantly as the input voltage increases. This indicates that the applied electric field can augment the stretch in flame, and the result is more obvious for leaner mixture. According to the analyses of the combustion pressure variation and the heat release rate, the peak combustion pressure Pmax increases and its appearance time tp is advanced with the increase of the input voltage. For the mixture of λ = 1.6 at the input voltage of −12 kV, Pmax increases by almost 12.3%, and tp is advanced by almost 31.4%, compared to the case of without electric fields. In addition, the normalized mass burning rate and the accumulated mass fraction burned are all enhanced substantially, and the flame development duration and the rapid burning duration are remarkably reduced with the increase of the input voltage, and again, the influence of electric field is more profound for leaner mixtures. The results can be explained by the electric field-induced stretch effects on lean burn methane-air mixture.

    Full Text Available Background Electrical burns are one of the most devastating types of injuries, and can becharacterized by the conduction of electric current through the deeper soft tissue such asvessels, nerves, muscles, and bones. For that reason, the extent of an electric burn is veryfrequently underestimated on initial impression.Methods From July 1999 to June 2006, we performed 15 cases of toe tissue transfer for thereconstruction of finger defects caused by electrical burns. We performed preoperative rangeof motion exercise, early excision, and coverage of the digital defect with toe tissue transfer.Results We obtained satisfactory results in both functional and aesthetic aspects in all 15cases without specific complications. Static two-point discrimination results in the transferredtoe cases ranged from 8 to 11 mm, with an average of 9.5 mm. The mean range of motionof the transferred toe was 20° to 36° in the distal interphalangeal joint, 16° to 45° in theproximal interphalangeal joint, and 15° to 35° in the metacarpophalangeal joint. All of thepatients were relatively satisfied with the function and appearance of their new digits.Conclusions The strategic management of electrical injury to the hands can be both challengingand complex. Because the optimal surgical method is free tissue transfer, maintenance ofvascular integrity among various physiological changes works as a determining factor for thepostoperative outcome following the reconstruction.

    Electrical burns caused by high voltage are responsible for extensive tissue damage. This damage continues in the days following the accident because of the heat deriving from the Joule effect and vascular microthrombosis. In such cases of destruction of the periostum and the calvarium we use coverage flaps. From June 1997 to June 2008, 15 patients were treated for loss of scalp substance due to high-voltage electric burns. The loss, in the tonsural region and varying in size from 9 to 11 cm, was reliably covered per primam in the first week following the accident using axial and multiple coverage flaps.

    Patient: Male, 32 Final Diagnosis: Thoracic duct chylous fistula Symptoms: Fistula Medication: — Clinical Procedure: A boneless muscle flap transplantatio Specialty: — Objective: Rare disease Background: As patients with thoracic duct injuries often suffer from severe local soft tissue defects, integrated surgical treatment is needed to achieve damage repair and wound closure. However, thoracic duct chylous fistula is rare in burn patients, although it typically involves severe soft tissue damage in the neck or chest. Case Report: A 32-year-old male patient fell after accidentally contacting an electric current (380 V) and knocked over a barrel of sulfuric acid. The sulfuric acid continuously poured onto his left neck and chest, causing combined electrical and sulfuric acid burn injuries to his anterior and posterior torso, and various parts of his limbs (25% of his total body surface area). During treatment, chylous fistula developed in the left clavicular region, which we diagnosed as thoracic duct chylous fistula. We used diet control, intravenous nutritional support, and continuous somatostatin to reduce the chylous fistula output, and hydrophilic silver ion-containing dressings for wound coverage. A boneless muscle flap was used to seal the left clavicular cavity, and, integrated, these led to resolution of the chylous fistula. Conclusions: Patients with severe electric or chemical burns in the neck or chest may be complicated with thoracic duct injuries. Although conservative treatment can control chylous fistula, wound cavity filling using a muscle flap is an effective approach for wound healing. PMID:27725628

    The purpose of this project is to investigate the suitability of lead-bismuth cooled fast reactors for producing low-cost electricity as well as for actinide burning. The goal is to identify and analyze the key technical issues in core neutronics, materials, thermal-hydraulics, fuels, and economics associated with the development of this reactor concept. The choice of lead-bismuth for the reactor coolant is an actinide burning fast reactor offers enhanced safety and reliability. The advantages of lead-bismuth over sodium as a coolant are related to the following material characteristics: chemical inertness with air and water; higher atomic number; lower vapor pressure at operating temperatures; and higher boiling temperature. Given the status of the field, it was agreed that the focus of this investigation in the first two years will be on the assessment of approaches to optimize core and plant arrangements in order to provide maximum safety and economic potential in this type of reactor.

    A high-voltage electrical burn caused extensive deep muscle injuries beneath a relatively small skin wound at the contact point. Hidden, undetected deep muscle injuries have a tendency for progressive tissue necrosis, which can lead to major amputations or sepsis. The radiologic features of this rare, sometimes life-threatening injury have occasionally been described in the literature. However, to the best of our knowledge, there have been no reports on a case of pyogenic arthritis of the ankle joint following a high-voltage electrical burn involving the lower extremity. We report a case of the pyogenic arthritis of the ankle joint following a high-voltage electrical burn involving the lower extremity.

    A new method of sintering Ca3SiO5 by the combination of conventional and microwave heating methods was studied. The influence of transitional metal oxides such as Fe2O3, Cr2O3, MnO2, and V2O5 used as the additive of microwave absorption on the mi- crowave-promoted burning of Ca3SiO5 was investigated. The experimental results indicate that the new burning technique is capable of promoting the sintering of Ca3SiO5. At 1200-1300℃ in an electric furnace, Ca3SiO5 can be obtained only when the sample is heat- ed in a microwave for 110-240 s, and the free lime content is below 40wt%. Based on the experiments, Fe2O3, Cr2O3, MnO2, and V2O5 can enhance microwave sintering. Amongst them, Cr2O3 is the most effective. The characteristic of the X-ray diffraction peaks of Ca3SiO5 is similar to those of standard Ca3SiO5, but the peaks are wider.

    We report the delayed sequelae arising in a case of electrical injury, reviewing the literature on the subject and focusing on the MRI findings of the brain. A 23-year-old male suffered burns to the left parietal scalp, both feet, and the anterior chest wall. Neurological symptoms and MRI abnormalities appeared 14 days after the insult and continued for about three months. T1-weight MR images demonstrated homogeneous hypointensity, while T2-weighted images depicted hyperintense finger-like projections. Contrast-enhanced T1-weighted images demonstrated strong band-like enhancement, indicating meningeal hyperemia. Follow-up MR imaging showed that the lesion had disappeared, indicating that the cerebral edema and meaningeal hyperemia were reversible.

    Background: A high-voltage electrical burn is often associated with deep muscle injuries. Hidden, undetected deep muscle injuries have a tendency for progressive tissue necrosis, and this can lead to major amputations or sepsis. MRI has excellent soft tissue contrast and it may aid in differentiating the areas of viable deep muscle from the areas of non-viable deep muscle. Purpose: To describe the MR imaging findings of a high-voltage electrical burn in the upper extremity with emphasis on the usefulness of the gadolinium-enhanced MRI and to compare the MR imaging findings with angiography. Material and Methods: We retrospectively reviewed the imaging studies of six patients with high-voltage electrical burns who underwent both MRI and angiography at the burn center of our hospital from January 2005 to December 2009. The imaging features were evaluated for the involved locations, the MR signal intensity of the affected muscles, the MR enhancement pattern, the involved arteries and the angiographic findings (classified as normal, sluggish flow, stenosis or occlusion) of the angiography of the upper extremity. We assessed the relationship between the MR imaging findings and the angiographic findings. Results: The signal intensities of affected muscles were isointense or of slightly high signal intensity as compared with the adjacent unaffected skeletal muscle on the T1-weighted MR images. Affected muscles showed heterogenous high signal intensity relative to the adjacent unaffected skeletal muscle on the T2- weighted images. The gadolinium-enhanced T1-weighted images showed diffuse inhomogeneous enhancement or peripheral rim enhancement of the affected muscles. The angiographic findings of the arterial injuries showed complete occlusion in three patients, severe stenosis in two patients and sluggish flow in one patient. Of these, the five patients with complete occlusion or severe stenosis on angiography showed non-perfused and non-viable areas of edematous muscle on

    Negative pressure wound therapy is a non-invasive treatment that uses under atmospheric pressure to increase blood supply to the wound, stimulating the formation of granulation tissue, angiogenesis, proliferation of fibroblasts and endothelial cells. Negative pressure therapy has also the ability to decrease the bacterial load, reduce swelling and decrease exudate while maintaining a moist environment that facilitates healing. Our patient, a 17 year old male, suffered major third and fourth-degree high voltage electrical burns on 60% of the body surface, in November 2011. After the excision of the necrotic tissue (muscles and tendons), the lower extremity of the right leg- the tibial bone, the fibula, external and internal malleoli became exposed circularly. The soft-tissue defect was partially covered by using an internal twin muscle flap and free split skin. Then, a cross leg flap technique has been used, partially covering the defect with a contralateral thigh flap. Surface swab cultures were positive for Pseudomonas aeruginosa. In October 2013 the patient was transferred to our department. The clinical examination of the right leg showed that the tibial bone had been exposed on an area of 15/3 cm in the lower half. The peroneal malleolus had also been exposed. The resection of the devitalized, exposed tibia and the avivement of the wound edges were performed. Then the NPWT was started and performed by intermittent suction. Local cleansing, soft-tissue avivement and dressing changes were performed twice a week for 6 weeks. After six weeks of NPWT and eleven dressing changes under general anaesthesia, the wounds were ready for skin grafting. Granulation tissue was formed, covering the entire surface of both the tibia bone and the peroneal malleolus. Both receptor beds were covered with free skin graft harvested from the ipsilateral thigh. The mechanical suture of the skin grafts was performed and the grafts were covered with damp dressing. By using the NPWT it

    The electric burn is a kind of special injury, in which the injured areas are not big, but deep tissues and organs are often injured, resulting in higher rates of mortality and amputation than thermal injury. In the process of management, besides the treatment for systemic and pathologic changes, wound repair is also emphasized for restoration of function. In the past 50 years, ten thound patients with electric burn were cured in our country, including hundreds of severe electric burn patients with extensive injury. Lots of operative regimes for electric burn were developed, and the scope of experimental research was broadening. As aresult, six monographs concerning electric burns were published. However, clinical management of severe electric burn to give a satisfactory result is still difficult, therefore further indepth research is necessary, especially in the field of the use of artificial skin, vessels, nerves, muscular tendon, etc. from gene and tissue engineering to improve quality of wound repair.

    The EERC developed an applied research consortium project to test cost-effective mercury (Hg) control technologies for utilities burning bituminous coals. The project goal was to test innovative Hg control technologies that have the potential to reduce Hg emissions from bituminous coal-fired power plants by {ge}90% at costs of one-half to three-quarters of current estimates for activated carbon injection (ACI). Hg control technology evaluations were performed using the EERC's combustion test facility (CTF). The CTF was fired on pulverized bituminous coals at 550,000 Btu/hr (580 MJ/hr). The CTF was configured with the following air pollution control devices (APCDs): selective catalytic reduction (SCR) unit, electrostatic precipitator (ESP), and wet flue gas desulfurization system (WFDS). The Hg control technologies investigated as part of this project included ACI (three Norit Americas, Inc., and eleven Envergex sorbents), elemental mercury (Hg{sup 0}) oxidation catalysts (i.e., the noble metals in Hitachi Zosen, Cormetech, and Hitachi SCR catalysts), sorbent enhancement additives (SEAs) (a proprietary EERC additive, trona, and limestone), and blending with a Powder River Basin (PRB) subbituminous coal. These Hg control technologies were evaluated separately, and many were also tested in combination.

    Burns are common injuries; more than 200,000 occur in Canada annually. Nearly all burn injuries can be managed on on outpatient basis. Appropriate treatment depends on burn depth, extent, and location. Special types of burns, such as chemical, tar, and electrical injuries, need specific management strategies. Prevention through education is important to reduce the incidence of burns.

    Full Text Available A significant burn injury is a serious and mortal event. The most important threat to life is hypovolemic shock with complex pathophysiologic mechanisms. Burn depth is classified as first, second, or third degree. Local inflammatory response results a vasodilatation and an increase in vascular permeability. A burn injury is a three dimensional ischemic wound. Zone of coagulation is the zone with maximum damage. Zone of stasis consists of damaged but viable tissues, the tissue is salvageable. In zone of hyperemia tissue perfusion is increased. At the beginning, cardiac output falls and systemic vascular resistance increases; cardiac performance improves as hypovolemia is corrected with fluid resuscitation. While cardiac output increases systemic vascular resistance falls below normal values and a hypermetabolic state develops. Pulmonary vascular resistance increases immediately after thermal injury and this is more prolonged. To avoid secondary pulmonary complications, the smallest resuscitation volume of fluids that maintains adequate tissue perfusion should be given. Changes parallel to the cardiovascular response develop in other organ systems. The reasons of burn injury can be thermal, electrical, chemical or radiation. It is important to know the exact mechanism of burn injury because of different therapies for a specific cause. In this review information about burn depth, local and systemic responses to burn injury and major causes of burn injury are presented.

    Initial management of minor and moderate, uncomplicated burn injury focuses on wound management and patient comfort. Initial management of patients with major burn injury requires airway support, fluid resuscitation for burn shock, treatment for associated trauma and preexisting medical conditions, management of adynamic ileus, and initial wound treatment. Fluid resuscitation, based on assessment of the extent and depth of burn injury, requires administration of intravenous fluids using resuscitation formula guidelines for the initial 24 hours after injury. Inhalation injury complicates flame burns and increases morbidity and mortality. Electrical injury places patients at risk for cardiac arrest, metabolic acidosis, and myoglobinuria. Circumferential full-thickness burns to extremities compromise circulation and require escharotomy or fasciotomy. Circumferential torso burns compromise air exchange and cardiac return. Loss of skin function places patients at risk for hypothermia, fluid and electrolyte imbalances, and systemic sepsis. The first 24 hours after burn injury require aggressive medical management to assure survival and minimize complications. PMID:8489882

    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.

  6. Unusual explosive growth of a squamous cell carcinoma of the scalp after electrical burn injury and subsequent coverage by sequential free flap vascular connection – a case report

    International Nuclear Information System (INIS)

    Squamous cell carcinomos may arise from chronic ulcerating wounds in scars, most commonly postburn scars. Tumour growth usually takes place over months to years. Localization on the scalp is a relatively rare condition. This report presents the case of a 63-year-old man with chronic ulceration of a postburn scar of the scalp due to an electrical burn 58 years ago. Sudden tumour growth started within weeks and on presentation already had extended through the skull into frontal cortex. After radical tumour resection, defect was covered with a free radial forearm flap. Local recurrence occurred 6 weeks later. Subsequent wide excision including discard of the flap and preservation of the radial vessels was followed by transfer of a free latissimus dorsi muscle flap, using the radial vessels of the first flap as recipient vessels. The patient received radiotherapy post-operatively. There were no problems with flap survivals or wound healing. Due to rapidly growing recurrence the patient died 2 months later. Explosive SCC tumour growth might occur in post-burn scars after more than 50 years. As a treatment option the use of sequential free flap connections might serve in repeated extensive tumour resections, especially in the scalp region, where suitable donor vessels are often located in distance to the defect

    The American Burn Association, Children's Burn Foundation, and Christian Medical College in Vellore, India have partnered together to improve pediatric burn care in Southern India. We report the demographics and outcomes of burns in this center, and create a benchmark to measure the effect of the partnership. A comparison to the National Burn Repository is made to allow for generalization and assessment to other burn centers, and to control for known confounders such as burn size, age, and mechanism. Charts from the pediatric burn center in Vellore, India were retrospectively reviewed and compared with data in the American Burn Association National Burn Registry (NBR) for patients younger than 16 years. One hundred nineteen pediatric patients with burns were admitted from January 2004 through April 2007. Average age was 3.8 years; average total body surface area burn was 24%: 64% scald, 30% flame, 6% electric. Annual death rate was 10%, with average fatal total body surface area burn was 40%. Average lengths of stay for survivors was 15 days. Delay of presentation was common (45% of all patients). Thirty-five of 119 patients received operations (29%). Flame burn patients were older (6.1 years vs 2.6 years), larger (30 vs 21%), had a higher fatality rate (19.4 vs 7.7%), and more of them were female (55 vs 47%) compared with scald burn patients. Electric burn patients were oldest (8.3 years) and all male. When compared with data in the NBR, average burn size was larger in Vellore (24 vs 9%). The mortality rate was higher in Vellore (10.1 vs 0.5%). The average mortal burn size in Vellore was smaller (40 vs 51%). Electric burns were more common in Vellore (6.0 vs 1.6%). Contact burns were almost nonexistent in Vellore (0.9 vs 13.1%). The differences in pediatric burn care from developing health care systems to burn centers in the US are manifold. Nonpresentation of smaller cases, and incomplete data in the NBR explain many of the differences. However, burns at this

    The use of light water at supercritical pressures as the coolant in a nuclear reactor offers the potential for considerable plant simplification and consequent capital and O&M cost reduction compared with current light water reactor (LWR) designs. Also, given the thermodynamic conditions of the coolant at the core outlet (i.e. temperature and pressure beyond the water critical point), very high thermal efficiencies of the power conversion cycle are possible (i.e. up to about 45%). Because no change of phase occurs in the core, the need for steam separators and dryers as well as for BWR-type re-circulation pumps is eliminated, which, for a given reactor power, results in a substantially shorter reactor vessel and smaller containment building than the current BWRs. Furthermore, in a direct cycle the steam generators are not needed. If no additional moderator is added to the fuel rod lattice, it is possible to attain fast neutron energy spectrum conditions in a supercritical water-cooled reactor (SCWR). This type of core can make use of either fertile or fertile-free fuel and retain a hard spectrum to effectively burn plutonium and minor actinides from LWR spent fuel while efficiently generating electricity. One can also add moderation and design a thermal spectrum SCWR. The Generation IV Roadmap effort has identified the thermal spectrum SCWR (followed by the fast spectrum SCWR) as one of the advanced concepts that should be developed for future use. Therefore, the work in this NERI project is addressing both types of SCWRs.

  14. Complicated Burn Resuscitation.

    Harrington, David T

    2016-10-01

    More than 4 decades after the creation of the Brooke and Parkland formulas, burn practitioners still argue about which formula is the best. So it is no surprise that there is no consensus about how to resuscitate a thermally injured patient with a significant comorbidity such as heart failure or cirrhosis or how to resuscitate a patient after an electrical or inhalation injury or a patient whose resuscitation is complicated by renal failure. All of these scenarios share a common theme in that the standard rule book does not apply. All will require highly individualized resuscitations. PMID:27600129

    For five decades it has been recognized that severe burn injury may precipitate in marked alterations in im-mune function,resulting in life-threatening systemic infections,sepsis,multiple organ failure,and even death.Extensive and deep burns exert widespread and profound impacts on various cells and molecules of the immune system.The general charac-teristics of abnormal immune responses following major burns are hyperinflammatory response and hypoimmune response of innate and adaptive immunity.These are recognized as postbum im-mune dysfunction(PID).The stress reaction,massive necrotic tissue,shock,infection,malnutrition and various therapeutic procedures after burns alter the microenvironment of the immune cells and molecules in which they reside,and consequently re-suit in the changes in immune cells and their secretions in quan.tity and/or activity,and also aberrant signal transduction in dif-ferent immune cells.These events constitute the cellular and molecular ases in the pathogenesis of PID.The main clinical consequences of PID include tissue damages and increased SUS-ceptibility to opportunistic pathogens caused by refractory inflam-mation and suppressed adaptive immunity.In order to decrease the morbidity of these lethal complications,efforts to improve the immune dysfunction after burn injury have been made not only at the integral level of etiological factors,but also at the cellular and molecular levels of its mechanisms.In this review,all these above.mentioned aspects of PID are comprehensively discussed.

  7. Hole burning with pressure and electric field: A window on the electronic structure and energy transfer dynamics of bacterial antenna complexes

    Energy Technology Data Exchange (ETDEWEB)

    Wu, H.M.

    1999-02-12

    Light-harvesting (LH) complexes of cyclic (C{sub n}) symmetry from photosynthetic bacteria are studied using absorption and high pressure- and Stark-hole burning spectroscopies. The B800 absorption band of LH2 is inhomogeneously broadened while the B850 band of LH2 and the B875 band of the LH1 complex exhibit significant homogeneous broadening due to ultra-fast inter-exciton level relaxation. The B800{r_arrow}B850 energy transfer rate of ({approximately}2 ps){sup {minus}1} as determined by hole burning and femtosecond pump-probe spectroscopies, is weakly dependent on pressure and temperature, both of which significantly affect the B800-B850 energy gap. The resilience is theoretically explained in terms of a modified Foerster theory with the spectral overlap provided by the B800 fluorescence origin band and weak vibronic absorption bands of B850. Possible explanations for the additional sub-picosecond relaxation channel of B800 observed with excitation on the blue side of B800 are given. Data from pressure and temperature dependent studies show that the B800 and B850 bacteriochlorophyll a (BChl a) molecules are weakly and strongly excitonically coupled, respectively, which is consistent with the X-ray structure of LH2. The B875 BChl a molecules are also strongly coupled. It is concluded that electron-exchange, in addition to electrostatic interactions, is important for understanding the strong coupling of the B850 and B875 rings. The large linear pressure shifts of {approximately}{minus}0.6 cm{sup {minus}1}/MPa associated with B850 and B875 can serve as important benchmarks for electronic structure calculations.

    A large proportion of burns in developing countries are related to the nature of domestic appliances used for cooking, heating, and lighting. Our overview of the problem elucidated the need for better surveillance with epidemiologic studies, which will more accurately assess the true incidence in vulnerable populations. This paper will create a framework for envisaging new approaches to the problem and begin to evaluate the strengths and weaknesses of proposed interventions. We used the Haddon Matrix to accumulate proposed interventions that encompass a pre-event, event, and post-event timeline. We propose an initial strategic outline plan for interventions based on values that are suited to the problem and the setting, are culturally appropriate, and can be employed in a reasonable period of time for a sustained period to ensure success. Recommended action steps include promoting the use of alternative energy sources, encouraging an integrated approach to finding interdisciplinary solutions, devising a better system of kerosene containerization, re-engineering appliance designs, legislating for enforcement of health and safety standards, taking a holistic approach through government inter-departmental collaboration, formally discouraging corruption, encouraging ventilation of cooking or living areas, implementing building codes, educating consumers, and training caregivers and health and emergency workers.

    Fast-burning mechanism describes the rapid penetration, with a sharp-shaped wave-front, of a strong magnetic field into a conductive metal whose electric resistance poses an abrupt rise at some critical temperature. With its wave-front sweeping over a solid metal, the fast-burning can melt or vaporize the metal very rapidly. This paper derives formulas for the existence conditions and wave-front velocity of a fast-burning.

    2002-03-01

    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.

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.

    Full Text Available Background/Aim. Burns are common injuries with frequency depending on human factors, development of protection, industry and traffic, eventual wars. Organized treatment of major burn injuries has tremendous medical, social and economic importance. The aim of this study was to analyze initial treatment of major and moderate burns, to compare it with the current recommendations and to signify the importance of organized management of burns. Methods. In a prospective study 547 adult patients with major burns were analyzed, covering a period of eight years, with the emphasis on the initial hospital admission and emergency care for burns greater than 10% of total body surface area (TBSA. Results. In the different groups of major burns, the percentage of hospital admission was: 81.5 in burns greater than 10% TBSA, 37.7 in burns of the functional areas, 54.5 in the III degree burns, 81.6 in electrical burns, 55.9 in chemical burns, 61.9 in inhalation injury, 41.0 in burns in patients with the greater risk and 100 in burns with a concomitant trauma. In the group of 145 patients with burns greater than 10% TBSA, intravenous fluids were given in 87 patients, analgesics in 45, corticosteroids in 29, antibiotics in 23 and oxygen administration in 14. In the same group, wound irrigation was done in 14.4%, removing of the clothing and shoes in 29.6%, elevation of the legs in 8.9% and prevention of hypothermia in 7.6% of the victims. There were no initial estimations of burn extent (percentage of a burn, notes about the patient and injury and tetanus immunizations. Conclusion. Based on these findings, it is concluded that there should be much more initial hospital admissions of major burns, and also, necessary steps in the emergency care of burns greater than 10% TBSA should be taken more frequently. On the other side, unnecessary or wrong steps should be avoided in the initial burn treatment.

  4. Critical issues in burn care.

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

    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.

    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.

    Fusion research and development has two aspects. One is an academic research on science and technology, i.e., discovery and understanding of unexpected phenomena and, development of innovative technology, respectively. The other is energy source development to realize fusion as a viable energy future. Fusion research has been made remarkable progress in the past several decades, and ITER will soon realize burning plasma that is essential for both academic research and energy development. With ITER, scientific research on unknown phenomena such as self-organization of the plasma in burning state will become possible and it contributes to create a variety of academic outcome. Fusion researchers will have a responsibility to generate actual energy, and electricity generation immediately after the success of burning plasma control experiment in ITER is the next important step that has to be discussed seriously.

    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.

    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.

    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.

  9. Waste: energy to burn

    International Nuclear Information System (INIS)

    Incinerated, transformed into fuel or a gas, waste is a versatile source of energy. It is as once a problem and a resource that is increasingly the focus of green policies. According to the 2009 World Waste Survey, between 3.4 and 4 billion tons of waste are produced each year worldwide. Leading the pack is China, with 300 million tons produced in 2005, followed closely by the United States, with 238 million tons. But the United States wins the per capita count with 760 kg of waste produced per year per inhabitant; Australia comes in second. In Europe, 500 kg of waste is produced per capita per year for a total of 2 billion tons generated annually, and a growth rate of 10% in ten years' time. Between 2/3 and 3/4 of these waste materials are sorted, and a portion of them is recycled. The rest is either carted away to a dumping ground, or incinerated. But this waste is primarily domestic, and still contains energy, energy that can be recovered. The added bonus is two-fold: an additional source of energy is created by transforming waste, called waste-to- wheel or waste-to-energy (WTE), and the decomposition of organic waste does not give off GHGs. Two ways are known today to transform wastes into energy: the thermal process, where heat is extracted from the waste (and sometimes converted into electricity), and the non-thermal process, which comprises collecting energy in a chemical form (biogas, biofuel). Both technologies depend on the type of waste to be treated: plastic materials, household refuse, fermentable elements, sludge residue from sewage treatment plants, agricultural waste, forestry industry waste, etc. The thermal process is by far the most widely employed. 74% of waste is incinerated in Japan, and around 30 to 55% in most European countries. The second process does not burn waste and is better suited to wet and organic matter, i.e., to waste that contains quantities of biomass: fermentable waste, sludge, agricultural waste and the gas given off at

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

    A case involving a five-month-old girl brought to the emergency department with burns over her abdomen is described. The child was reported to have spilled two small bottles of beauty nail adhesive on her clothes while her mother was preparing dinner. After undressing the infant, the mother discovered several lesions on the child’s abdomen and quickly sought medical attention. Given the unusual circumstances of the presentation, the child was hospitalized for both treatment and supervision. The beauty nail adhesive contained cyanoacrylate. In addition to its well-appreciated adhesive capacity, cyanoacrylate, in the presence of cotton or other tissues, is known to produce an exothermic reaction that may cause burns. Cyanoacrylate-based products, due to their possible adverse effects, should be kept away from children as advised. Odd injuries should always raise concerns about the possibility of inflicted injury.

    Hydrofluoric acid is increasingly used as a rust remover and detergent. Dermal contact with hydrofluoric acid results in a chemical burn characterized by severe pain and deep tissue necrosis. It may cause electrolyte imbalances with lethal consequences. It is important to identify high-risk patients. 'High risk' is defined as a total affected body area > 3% or exposure to hydrofluoric acid in a concentration > 50%. We present the cases of three male patients (26, 31, and 39 years old) with hydrofluoric acid burns of varying severity and describe the subsequent treatments. The application of calcium gluconate 2.5% gel to the skin is the cornerstone of the treatment, reducing pain as well as improving wound healing. Nails should be thoroughly inspected and possibly removed if the nail is involved, to ensure proper healing. In high-risk patients, plasma calcium levels should be evaluated and cardiac monitoring is indicated.

    Xygalatas, Dimitris

    The Anastenaria are Orthodox Christians in Northern Greece who observe a unique annual ritual cycle focused on two festivals, dedicated to Saint Constantine and Saint Helen. The festivals involve processions, music, dancing, animal sacrifices, and culminate in an electrifying fire-walking ritual....... Carrying the sacred icons of the saints, participants dance over hot coals as the saint moves them. The Burning Saints presents an analysis of these rituals and the psychology behind them. Based on long-term fieldwork, The Burning Saints traces the historical development and sociocultural context of the...... Greek fire-walking rituals. As a cognitive ethnography, the book aims to identify the social, psychological and neurobiological factors which may be involved and to explore the role of emotional and physiological arousal in the performance of such ritual. A study of participation, experience and meaning...

    A unique, preventable, 2.8 x 3.7-cm, full-thickness scalp burn resulted after a woman underwent a professional color-highlighting procedure at a hair salon. The burn appeared to result from scalp contact with aluminum foil that had been overheated by a hair dryer during the procedure. The wound required debridement and skin grafting and 3 subsequent serial excisions to eliminate the resulting area of burn scar alopecia. The preventive aspects of this injury are discussed.

    An acoustic emission (AE) method is being used to measure the burning rate of solid propellant strands. This method has a precision of 0.5% and excellent burning rate correlation with both subscale and large rocket motors. The AE procedure burns the sample under water and measures the burning rate from the acoustic output. The acoustic signal provides a continuous readout during testing, which allows complete data analysis rather than the start-stop clockwires used by the conventional method. The AE method helps eliminate such problems as inhibiting the sample, pressure increase and temperature rise, during testing.

    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.

  2. The ALMR actinide burning system

    International Nuclear Information System (INIS)

    The advanced liquid-metal reactor (ALMR) actinide burning system is being developed under the sponsorship of the US Department of Energy to bring its unique capabilities to fruition for deployment in the early 21st century. The system consists of four major parts: the reactor plant, the metal fuel and its recycle, the processing of light water reactor (LWR) spent fuel to extract the actinides, and the development of a residual waste package. This paper addresses the status and outlook for each of these four major elements. The ALMR is being developed by an industrial group under the leadership of General Electric (GE) in a cost-sharing arrangement with the US Department of Energy. This effort is nearing completion of the advanced conceptual design phase and will enter the preliminary design phase in 1994. The innovative modular reactor design stresses simplicity, economics, reliability, and availability. The design has evolved from GE's PRISM design initiative and has progressed to the final stages of a prelicensing review by the US Nuclear Regulatory Commission (NRC); a safety evaluation report is expected by the end of 1993. All the major issues identified during this review process have been technically resolved. The next design phases will focus on implementation of the basic safety philosophy of passive shutdown to a safe, stable condition, even without scram, and passive decay heat removal. Economic projections to date show that it will be competitive with non- nuclear and advanced LWR nuclear alternatives

    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.

    2016-10-01

    The inflammatory state after burn injury is characterized by an increase in capillary permeability that results in protein and fluid leakage into the interstitial space, increasing resuscitative requirements. Although the mechanisms underlying increased capillary permeability are complex, damage from reactive oxygen species plays a major role and has been successfully attenuated with antioxidant therapy in several disease processes. However, the utility of antioxidants in burn treatment remains unclear. Vitamin C is a promising antioxidant candidate that has been examined in burn resuscitation studies and shows efficacy in reducing the fluid requirements in the acute phase after burn injury.

    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

    On the morning of June 9, 2009, an explosion occurred at a manufacturing plant in Garner, North Carolina. By the end of the day, 68 injured patients had been evaluated at the 3 Level I trauma centers and 3 community hospitals in the Raleigh/Durham metro area (3 people who were buried in the structural collapse died at the scene). Approximately 300 employees were present at the time of the explosion, when natural gas being vented during the repair of a hot water heater ignited. The concussion from the explosion led to structural failure in multiple locations and breached additional natural gas, electrical, and ammonia lines that ran overhead in the 1-story concrete industrial plant. Intent is the major difference between this type of accident and a terrorist using an incendiary device to terrorize a targeted population. But while this disaster lacked intent, the response, rescue, and outcomes were improved as a result of bioterrorism preparedness. This article discusses how bioterrorism hospital preparedness planning, with an all-hazards approach, became the basis for coordinated burn surge disaster preparedness. This real-world disaster challenged a variety of systems, hospitals, and healthcare providers to work efficiently and effectively to manage multiple survivors. Burn-injured patients served as a focus for this work. We describe the response, rescue, and resuscitation provided by first responders and first receivers as well as efforts made to develop burn care capabilities and surge capacity.

    Deep partial-thickness burns had been inflicted on the perineal area of an infant who was recently treated in our Burn Center. The burns were a result of advice to the patient's mother by a pediatrician. The doctor told her to use a hair dryer to prevent diaper rash. We surveyed pediatricians, well-baby clinics, and pediatric nurse practitioners in our area and found that approximately half of them advised the use of hair dryers to treat or prevent diaper rash. We tested four widely available hand-held hair dryers to determine potential for inflicting burn injury. All of the dryers are capable of delivering air heated to at least 53 degrees C after 2 minutes of use. We believe that warnings against the use of hair dryers for perineal hygiene should be included in burn prevention programs.

  16. Fuel burning and climate

    International Nuclear Information System (INIS)

    Emission of soot particles and other air pollution indoors constitutes a considerable health hazard for a major part of the population in many developing countries, one of them being China. In these countries problems relating to poverty are the most important risk factors, undernourishment being the dominating reason. Number four on the list of the most serious health hazards is indoor air pollution caused by burning of coal and biomass in the households. Very high levels of soot particles occur indoors because of incomplete combustion in old-fashioned stoves and by use of low quality fuel such as sticks and twigs and straw and other waste from agriculture. This leads to an increase in a series of acute and chronic respiratory diseases, including lung cancer. It has been pointed out in recent years that emissions due to incomplete combustion of coal and biomass can contribute considerably to climate changes

    Burn injury is a complex traumatic event with various local and systemic effects, affecting several organ systems beyond the skin. The pathophysiology of the burn patient shows the full spectrum of the complexity of inflammatory response reactions. In the acute phase, inflammation mechanism may have negative effects because of capillary leak, the propagation of inhalation injury and the development of multiple organ failure. Attempts to mediate these processes remain a central subject of burn care research. Conversely, inflammation is a necessary prologue and component in the later-stage processes of wound healing. In this review, we are attempting to present the current science of burn wound pathophysiology and wound healing. We also describe the evolution of innovative strategies for burn management.

Enhanced gas generation rates (EGGR of propellants during and after electrical discharges are verified in the experiments. A modified 0D internal ballistic model is established to simulate the ETC launch. According to the measured pressure and electrical parameters, a transient burning rate law including the influence of EGGR coefficient by electric power and pressure gradient (dp/dt is added into the model. The EGGR coefficient of 4/7 high-nitrogen solid propellant is equal to 0.005 MW−1. Both simulated breech pressure and projectile muzzle velocity accord with the experimental results well. Compared with Woodley's modified burning rate law, the breech pressure curves acquired by the transient burning rate law are more consistent with test results. Based on the parameters calculated in the model, the relationship among propellant burning rate, pressure gradient (dp/dt and electric power is analyzed. Depending on the transient burning rate law and experimental data, the burning of solid propellant under the condition of plasma is described more accurately.

After the bum patient successfully passes the resuscitation period, the burn wound represents the greatest threat to survival. History Since the dawn of civilization, man has been trying to find an agent which would help burn wounds heal, and at the same time, not harm general condition of the injured. It was not until the XX century, after the discovery of antibiotics, when this condition was fulfilled. In 1968, combining silver and sulfadiazine, fox made silver-sulfadiazine, which is a 1% hydro-soluble cream and a superior agent in topical treatment of burns today. Current topical agents None of the topical antimicrobial agents available today, alone or combined, have the characteristics of ideal prophylactic agents, but they eliminate colonization of burn wound, and invasive infections are infrequent. With an excellent spectrum of activity, low toxicity, and ease of application with minimal pain, silver-sulfadiazine is still the most frequently used topical agent. Conclusion The incidence of invasive infections and overall mortality have been significantly reduced after introduction of topical burn wound antimicrobial agents into practice. In most burn patients the drug of choice for prophylaxis is silver sulfadiazine. Other agents may be useful in certain clinical situations.

    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.

    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

    Hairdressing-related burns are preventable and therefore each case is one too many. We report a unique case of a 16-yr-old girl who suffered full-thickness chemical and thermal burns to the nape of her neck and superficial burns to the occiput after her hair had been dyed blond and placed under a dryer to accelerate the highlighting procedure. The wound on the nape of the neck required surgical debridement and skin grafting. The grafted area resulted in subsequent scar formation.

In our region we deal with this type of wounds as team work, multidisciplinary approach carrying out many process starting by emergency treatment of acute burns till the social rehabilitation. The expansion technique was great help in improving the shape of scars, by using the expanding skin as full thickness grafts. Reconstruction of the anatomical units and application of aesthetic techniques (like rhinoplasty, lifting, tattooing and autologous fat injections) participate equally in improving the quality of results. Many examples of treatments of burns scars are shown.

    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.

    Three children with burn injuries caused by home hair dryers are described. In one patient the injury was believed to be accidental, and in the other two cases the injuries were deliberately caused by a caretaker. The lack of prior experience with hair dryer burns initially led to suspicion of other causes. The characteristics of each case aided in the final determination of accidental vs nonaccidental injury. These cases prompted testing of home hair dryers to determine their heat output. At the highest heat settings, the dryers rapidly generated temperatures in excess of 110 degrees C. After the dryers were turned off, the protective grills maintained sufficient temperatures to cause full-thickness burns for up to 2 minutes. These cases and the results of testing demonstrate that hair dryers must be added to the list of known causes of accidental and nonaccidental burns in children.

    Full Text Available An 18-year old woman was admitted to Motahari Burn Center suffering from 30% burns. Treatment modalities were carried out for the patient and she was discharged after 20 days. Three to four months later she developed hypertrophic scar on her chest and upper limbs .At the same time she developed galactorrhea in both breasts and had a disturbed menstrual cycle four months post-burn. On investigation, we found hyperprolactinemia and no other reasons for the high level of prolactin were detected. She received treatment for both the hypertrophic scar and the severe itching she was experiencing. After seven months, her prolactin level had decreased but had not returned to the normal level. It seems that refractory hypertrophic scar is related to the high level of prolactin in burns patients.

    Wound care in one of the most important prognostic factors in burn victims. Open wound carries risks for infection due to hypothermia, protein and fluid losses. In addition, unhealed wounds are the major risk factors for acute-subacute or chronic complications in burn patients. Although no exact algorithm exists for open wound treatment, early escarectomy or debridement together with grafting is the best option. Ointments together with topical epithelizing agents without dressings are generea...

  15. Waste - a burning issue

    International Nuclear Information System (INIS)

    Modern municipal waste incineration technology which incorporates energy recovery is being promoted as environmentally friendly. As such, it qualifies for subsidies when used by electric utilities as part of the United Kingdom Government's Non Fossil Fuel Obligation for electricity generation. It is argued, however, that this is a misuse of money intended to promote renewable energy sources. Incineration is primarily a waste disposal technology and an inefficient means for producing electricity. The environmental benefits claimed for incineration are that it reduces the volume of landfill, particularly plastics, that the ash residues are easier to handle than the original waste, that the methane production and smells from landfill are avoided, that transport costs are reduced and that energy reclaim offsets costs. Arguments to set against these benefits are presented. Incinerators are expensive to construct and beyond the construction phase offer little economic spin-off for the host community. The landfill reduction is not as great as claimed and the fly-ash from incinerators includes heavy metals in the form of metal chlorides which can be leached out instead of being chemically bound into the original plastic matrix. Dioxin pollution from incineration is still a significant concern. Overall more energy could be obtained by a programme of recycling and composting. (1 figure, 9 references) (UK)

  16. Erosive burning of solid propellants

    King, Merrill K.

    1993-01-01

    Presented here is a review of the experimental and modeling work concerning erosive burning of solid propellants (augmentation of burning rate by flow of product gases across a burning surface). A brief introduction describes the motor design problems caused by this phenomenon, particularly for low port/throat area ratio motors and nozzleless motors. Various experimental techniques for measuring crossflow sensitivity of solid propellant burning rates are described, with the conclusion that accurate simulation of the flow, including upstream flow development, in actual motors is important since the degree of erosive burning depends not only on local mean crossflow velocity and propellant nature, but also upon this upstream development. In the modeling area, a brief review of simplified models and correlating equations is presented, followed by a description of more complex numerical analysis models. Both composite and double-base propellant models are reviewed. A second generation composite model is shown to give good agreement with data obtained in a series of tests in which composite propellant composition and heterogeneity (particle size distribution) were systematically varied. Finally, the use of numerical models for the development of erosive burning correlations is described, and a brief discussion of scaling is presented.

  17. DIFFERENTIATING PERIMORTEM AND POSTMORTEM BURNING

    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

    The population of elderly patients is expected to rise continuously over the next decades due to global demographic changes. The elderly seem to be most vulnerable to burns and their management remains undoubtedly a challenge. A clear age margin for elderly patients is not yet defined, but most studies adhere to the inclusion of patients 65 years and above, but the general condition and social situation must be taken into account. The understanding of the physiological basis of aging and its related pathophysiological changes has only marginally influenced treatment and decision making in elderly burn patients. When looking at treatment regimens currently applied in elderly burn patients, the discussion of standards in intensive care as well as surgical strategies is ongoing. However, trends towards a moderate, non-aggressive resuscitation approach and careful inclusion of key parameters like physiological age, pre-burn functional status and premorbid conditions, seem to be useful guidelines for interdisciplinary treatment decisions. Once ordered for surgical treatment, the amount of body surface area operated in one session should be adapted to the general status of the patient. Even if older burn victims have a reported higher mortality rate than younger patients, improved therapeutic options have contributed to a reduced mortality rate even in the elderly over the last decades. As a result of improved outcome, more attention has to be given to a comprehensive rehabilitation program. This review will give an overview of the current literature and will draw attention to specific topics related to this important subpopulation of burn patients.

    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

    Objective To make comparison of advantages and disadvantages between one stage repair and staged repair of electric burn coupled with skull exposure and infection by soft tissue expander, and discuss the feasibility of one stage repair. Methods From June 1999 to December 2010 in our hospital, there were 64 infected patients suffering electric burn coupled with large areas of scalp defection and skull exposure,and the wound areas ranged from 180 to 480 cm2. After skull sequestra were taken out,the patients were respectively treated with one stage repair or staged repair by soft tissue expander. The repair effects of the two methods were observed. Results After the expander placement operation, the incidence rate of expander extrusion in the one - stage - repair group was higher than that in the staged - repair group. There were no statistically significant differences of the expander capsule infection and the incidence of skin flap necrosis between the two groups. Patients healed by the one stage repair had larger areas of alopecia on the incisional scars,but had shorter time of hospitalization and less expenses. Conclusion One stage repair is feasible in healing the electric burn coupled with skull exposure and infection,and can reduce both pain and economic burdens of the patients. However,it is vital to prevent expander extrusion during the early treatment.%目的 比较软组织扩张器一期修复和分期修复两种术式治疗电击伤颅骨外露并感染的优缺点,以及一期修复的可行性.方法 1999年6月~2010年12月收治的电击伤合并头皮缺损颅骨外露并感染的患者共64例,创面面积180-480 cm2.颅骨死骨凿除后,分别采用软组织扩张器行一期修复或分期修复,观察两种方式的修复效果.结果 两组患者扩张器埋置术后,一期修复组扩张器外露发生率高于两期修复组;两组扩张囊内感染、皮瓣坏死的发生率比较无明显统计学差异.一期修复组愈后头部切口

    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.

    2013-01-01

    This paper presents the DYON simulations of the plasma burn-through phase at Joint European Torus (JET) with the ITER-like wall. The main purpose of the study is to validate the simulations with the ITER-like wall, made of beryllium. Without impurities, the burn-through process of a pure deuterium plasma is described using DYON simulations, and the criterion for deuterium burn-through is derived analytically. The plasma burn-through with impurities are simulated using wall-sputtering models in the DYON code, which are modified for the ITER-like wall. The wall-sputtering models and the validation against JET data are presented. The impact of the assumed plasma parameters in DYON simulations are discussed by means of parameter scans. As a result, the operation space of prefill gas pressure and toroidal electric field for plasma burn-through in JET is compared to the Townsend avalanche criterion.

    Occupational therapy for severely burned patients includes individual exercise programmes, activities of daily living (ADL), assessment of the need for technical aids, splinting and pressure bandages, as well as psychological and social support. There are different focal points in the three stages of treatment. In the burn-care unit (first stage), if necessary, the patient is provided with splints. At this time the first contact is made. In the burn-care ward (second stage), the occupational therapy is focused on individual exercise programmes, dynamic splinting, ADL, and preparation for discharge from hospital. In the outpatient department (third stage), the aims of occupational therapy are: providing the patients with pressure bandages, checking of splints, assessment of the need for technical aids and special support if the patients have difficulties at home and work.

    Full Text Available A burn is a wound in which there is coagulative necrosis of the tissue, majority of which are caused by heat. Burn injury is a major public health problem in many areas of the world. Burns predispose to infection by damaging the protective barrier function of the skin, thus facilitating the entry of pa thogenic microorganisms and by inducing systemic immunosuppression . (1 OBJECTIVE : The present study was therefore undertaken to isolate and identify the aerobic bacterial flora in burn patients and its antibiotic susceptibility pattern. MATERIAL & METHODS : A total of 100 patients admitted with different degree of burns were studied. Wound swabs were taken with aseptic precautions by dry sterile cotton swab sticks. These swabs were transported to the microbiology laboratory and the isolates were identified based on standard microbiological methods. Antibiotic susceptibility testing was done by Kirby Bauer’s disc diffusion method. RESULT : A total of 127 bacterial pathogens were isolated from 100 patients. Of these, 69% were monomicrobial in nature and 28% wer e polymicrobial. The most frequent cause of infection was found to be Staphylococcus aureus (39.4%, followed by Pseudomonas aeruginosa (14.2%, Klebsiella pneumonia (13.4%, E.coli (8.7% and Acinetobacter species (7.9%.Out of the total Staphylococcus au reus isolates, 19 were Methicillin sensitive and 31 were Methicillin resistant (MRSA. All the MRSA strains were 100% sensitive to Vancomycin and Linezolid. The Pseudomonas aeruginosa isolates were most sensitive to Amikacin (9 4.4%, Fluroquinolones (61.1% . CONCLUSION : Staphylococcus aureus and Pseudomonas aeruginosa were major causes of infection in burn wounds. Therefore it is necessary to implement urgent measures for restriction of nosocomial infections, sensible limitation on the use of antimicrobial agents, strict disinfection and hygiene.

    Since the 1940s, the resuscitation of burn patients has evolved with dramatic improvements in mortality. The most significant achievement remains the creation and adoption of formulae to calculate estimated fluid requirements to guide resuscitation. Modalities to attenuate the hypermetabolic phase of injury include pharmacologic agents, early enteral nutrition, and the aggressive approach of early excision of large injuries. Recent investigations into the genomic response to severe burns and the application of computer-based decision support tools will likely guide future resuscitation, with the goal of further reducing mortality and morbidity, and improving functional and quality of life outcomes.

    Early removal of affected tissues from burn patients can significantly increase the success of their recovery, since burns continue to spread and damage surrounding tissues after hours of injury. The rationale behind this procedure is that burns trigger the body's immune system to overreact, causing additional damage. Therefore it is important to locate and identify the burn (area and thickness) so that it can be removed as quickly as possible. Our project explores the use of autofluorescence as a tool to identify the burned tissues from healthy ones. Here we present that our fluorescence results show differences between burned and normal skin in both its spectra and lifetime.

  11. Electrical cardioversion

    International Nuclear Information System (INIS)

    External electrical cardioversion was first performed in the 1950s. Urgent or elective cardioversions have specific advantages, such as termination of atrial and ventricular tachycardia and recovery of sinus rhythm. Electrical cardioversion is life-saving when applied in urgent circumstances. The success rate is increased by accurate tachycardia diagnosis, careful patient selection, adequate electrode (paddles) application, determination of the optimal energy and anesthesia levels, prevention of embolic events and arrythmia recurrence and airway conservation while minimizing possible complications. Potential complications include ventricular fibrillation due to general anesthesia or lack of synchronization between the direct current (DC) shock and the QRS complex, thromboembolus due to insufficient anticoagulant therapy, non-sustained VT, atrial arrhythmia, heart block, bradycardia, transient left bundle branch block, myocardial necrosis, myocardial dysfunction, transient hypotension, pulmonary edema and skin burn. Electrical cardioversion performed in patients with a pacemaker or an incompatible cardioverter defibrillator may lead to dysfunction, namely acute or chronic changes in the pacing or sensitivity threshold. Although this procedure appears fairly simple, serious consequences might occur if inappropriately performed. (author)

    2013-03-01

    This paper experimentally quantified the long-term effects of RF burn-in, in terms of burn-in and recovery times, and found the effects to be semipermanent. Specifically, most of the benefit could be realized after approximately 20 min of RF burn-in, which would then last for several months. Additionally, since similar effects were observed on both real and faux switches, the effects appeared to be of electrical rather than mechanical nature. These encouraging results should facilitate the application of the switches in RF systems, where high RF power could be periodically applied to rejuvenate the switches. © 2001-2011 IEEE.

  13. Wood would burn

    International Nuclear Information System (INIS)

    Absract: In view of the world-wide problem of energy sustainability and greenhouse gas production (carbon dioxide), it is timely to review the issues involved in generating heat and power from all fuels and especially new (to the UK) solid fuels, including high moisture fuels such as wood, SRF, oil shale, tar sands and brown coal, which will become major international fuels as oil and gas become depleted. The combustion properties of some of these materials are significantly different from traditional coal, oil and gas fuels, however the technology proposed herein is also applicable to these conventional fuels. This paper presents some innovative combustion system options and the associated technical factors that must be considered for their implementation. For clarity of understanding, the novel concepts will be largely presented in terms of a currently developing solid fuel market; biomass wood chips. One of the most important characteristics of many solid fuels to be used in the future (including oil shale and brown coal) is their high moisture content of up to 60%. This could be removed by utilising low grade waste heat that is widely available in industry to dry the fuel and thus reduce transport costs. Burning such dried wood for power generation also increases the energy available from combustion and thus acts as a thermal transformer by upgrading the low grade heat to heat available at combustion temperatures. The alternative approach presented here is to recover the latent heat by condensing the extrinsic moisture and the water formed during combustion. For atmospheric combustion, the temperature of the condensed combustion products is below the dew point at about 55-65 oC and is only suitable for recovery in an efficient district heating system. However, in order to generate power from the latent heat, the condensation temperature must be increased to the level where the heat can be used in the thermodynamic power cycle. This can be achieved by increasing

    The authors review the etiology of U.K. military burns in light of increasing hybrid warfare. Analysis of the nature of these injured personnel will provide commanders with the evidence to plan for on-going and future operations. Case notes of all U.K. Armed Forces burn injured patients who were evacuated to the Royal Centre for Defence Medicine were reviewed. Demographics, burn severity, pattern, and mortality details were included. There were 134 U.K. military personnel with burns requiring return to the United Kingdom during 2001-2007. The median age was 27 (20-62) years. Overall, 60% of burns seen were "accidental." Burning waste, misuse or disrespect of fuel, and scalds were the most prevalent noncombat burns. Areas commonly burned were the face, legs, and hands. During 2006-2007 in the two major conflicts, more than 59% (n = 36) of the burned patients evacuated to the United Kingdom were injured during combat. Burns sustained in combat represent 5.8% of all combat casualties and were commonly associated with other injuries. Improvised explosive device, minestrike, and rocket-propelled grenade were common causes. The mean TBSA affected for both groups was 5% (1-70). The majority of combat burn injuries have been small in size. Greater provision of flame retardant equipment and clothing may reduce the extent and number of combat burns in the future. The numbers of noncombat burns are being reduced by good military discipline. PMID:21422938

    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.

Patient presenting with the burning mouth sensation or pain is frequently encountered in clinical practice which poses a challenge to the treating clinician. Its exact etiology remains unknown which probably has multifactorial origin. It often affects middle or old age women and it may be accompanied by xerostomia and altered taste. Objective: To review the current concepts regarding etiopathogenesis, diagnosis and management of this disorder. Methods and methodology: A literature review was conducted on PubMed/Medline and Google scholar about the burning mouth syndrome and the representative articles were selected and reviewed. Conclusion: There is no universal consensus regarding diagnosis, etiology and treatment of BMS. BMS is a diagnosis of exclusion which probably has multifactorial origin. Various pharmacological and non pharmacological treatments are available but it is difficult to achieve curative treatment so reassurance is of great importance while treating the patients. Combination of cognitive behavioral therapy, alpha lipoic acid and/or clonazepam has shown promising results.

    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. PMID:20510518

    Hydrofluoric acid (HF) causes a unique chemical burn. Much of the current treatment knowledge of HF burns is derived from case reports, small case series, animal studies and anecdotal evidence. The management can be challenging because clinical presentation and severity of these burns vary widely. Plastic surgeons managing burn patients must have a basic understanding of the pathophysiology, the range of severity in presentation and the current treatment options available for HF burns. The present article reviews the current understanding of the pathophysiology and systemic effects associated with severe HF burns. Furthermore, it distinguishes between minor and life-threatening HF burns and describes several of the basic techniques that are available to treat patients with HF burns.

    A 70-year-old woman visited a Korean-style hot dry sauna room. The patient had a medical history of hypertension and hyperlipidemia. During the sauna, the patient slept for 30 minutes. During the sleep, the right medial thigh was covered with a fully wet towel. The patient sustained a second-degree burn on the right medial thigh area with multiple bullas. On physical examination, erythema, heating sensation, and swelling around the bullas were noted. The patient was admitted and received intravenous antibiotics for 7 days. A dressing with Silmazine 1% cream (sulfadiazine) was applied twice a day for prevention of local infection. The patient was discharged on day 14 without complication. In this case, the mechanism of the burn was different. Hot air has much thermal energy but is not conducted to the skin directly. A wet towel will have a relatively higher thermal capacity or heat capacity than a dry or damp towel, and the sodden water might be a medium for the conduction of thermal energy. Owing to the global popularity of sauna bathing, it is important to recognize all sources of sauna-related burns.

    A case of hydrofluoric acid (HF) burns of the eye is reported and a review is presented of our investigation into the mechanism of HF toxicity in ocular tissues. A number of therapeutic procedures that have been successful in the treatment of HF skin burns were studied in the rabbit for use in the eye. Immediate single irrigation with water, normal saline or isotonic magnesium chloride solution is the most effective therapy for ocular HF burns. Extrapolation of other skin burn treatments to use in the eye is unacceptable due to the toxicity of these agents in normal eyes and the additive damage caused in burned eyes. PMID:6886845

    Intravenous (IV) cannulation and sterile IV salt solutions may not be options in resource-limited settings (RLSs). This article presents recipes for fluid resuscitation in the aftermath of burns occurring in RLSs. Burns of 20% total body surface area (TBSA) can be resuscitated, and burns up to 40% TBSA can most likely be resuscitated, using oral resuscitation solutions (ORSs) with salt supplementation. Without IV therapy, fluid resuscitation for larger burns may only be possible with ORSs. Published global experience is limited, and the magnitude of burn injuries that successfully respond to World Health Organization ORSs is not well-described. PMID:27600127

    Maggs, William Ward

    Human beings were responsible for most of 12,000 forest fires in the southeastern United States that burned for 10 days in late October and early November 1987. 910 km2, mostly hardwood forest, were destroyed in the fires, with arson and carelessness as the primary causes, according to the U.S. Department of Agriculture Forest Service.Measured in monetary terms, the toll was more than $40 million in resource and property damage. While the amount of forest burned did not rival the 3390 km2 lost to fires in the western United States last summer, the human impact was severe in the southeast and all along the East Coast. Favorable winds blew smoke from the southern and central Appalachians as far north as New England and as far east as Delaware, and cool fall air close to the ground prevented the smoke from rising, thickening the air in many northeastern cities on November 8 and 9.

    The pharmacokinetics of fluconazole in nine adult patients with severe (30 to 95% total body surface area) burns were studied. There was no significant difference in half-life (t1/2), clearance (CL), or volume of distribution (V) over time in five patients on days 3 and 8 of the study (P > 0.05). Combined parameter estimates (means ± standard deviations) for all nine patients for the two study periods were as follows: t1/2, 24.4 ± 5.8 h; CL, 0.36 ± 0.09 ml/min/kg; and V, 0.72 ± 0.12 liters/kg. These estimates of t1/2 and CL in burn patients were approximately 13% shorter and 30% more rapid, respectively, than the most extreme estimates reported for other populations. PMID:9559811

    In the US, there are over 400,000 burn victims with 3,500 deaths in 2010. Recent evidence suggests that early removal of burn tissues can significantly increase the success of their recovery, since burns continue to spread and damage surrounding tissues after hours of injury. The rationale behind this procedure is that burns trigger the body's immune system to overreact, causing additional damage. Therefore, it is important to distinguish burn areas so that it can be removed. The problem with this is that it is difficult to recognize the margins of the burn area. In our project, we use polarized reflectance as a tool to identify the burned tissues from unburned ones.

    Paediatric burns occupy the third place in the severe accident statistics in Germany after traffic injuries and drowning. The paper reviews current treatment concepts of pre-hospital management, fluid resuscitation and surgical therapy in paediatric burned patients. Specific features in the approximation of the total body surface area burn and indications for transfer of paediatric burn victims to specialized units are discussed. The therapy of severe paediatric burns requires an interdisciplinary team consisting of especially skilled plastic or paediatric surgeons,anaesthetists, psychiatrists or psychologists, specifically trained nurses, physiotherapists and social workers. The rehabilitation process starts basically with admission to the burn unit. A tight cooperation between therapists and the relatives of the paediatric burn victim is needed for psychological recovery and reintegration into society.'The adaptation to the suffered trauma resulting in life-long disability and disfigurement is the main task of psychotherapy.

  18. Septicemia: The Principal Killer of Burns Patients

    2005-01-01

    Full Text Available Burn injury is a major problem in many areas of the world and it has been estimated that 75% of all deaths following burns are related to infection. Burns impair the skin’s normal barrier function thus allowing microbial colonization of the burn wounds and even with the use of topical antimicrobial agents, contamination is almost unavoidable. It is therefore essential for every burn institution to determine its specific pattern of burn wound microbial colonization, time related changes in predominant flora and antimicrobial resistance profiles. This would allow early management of septic episodes with proper empirical systemic antibiotics before the results of microbiologic culture becomes available, thus improving the overall infection-related morbidity and mortality. We attempted to examine the factors affecting risk of infection; strategies for infection control and prevention in burn victims.

    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. PMID:21991218

    Major burn patients have characteristics that make them especially susceptible to candidemia, but few studies focused on this have been published. The objectives were to evaluate the epidemiological, microbiological and clinical aspects of candidemia in major burn patients, determining factors associated with a poorer prognosis and mortality. We conducted a retrospective observational study of candidemia between 1996 and 2012 in major burn patients admitted to the La Fe University Hospital, Valencia, Spain. The study included 36 episodes of candidemia in the same number of patients, 55.6% men, mean age 37.33 years and low associated comorbidity. The incidence of candidemia varied between 0.26 and 6.09 episodes/1000 days stay in the different years studied. Candida albicans was the most common species (61.1%) followed by Candida parapsilosis (27.8%). Candidemia by C. krusei, C. glabrata or C. tropicalis were all identified after 2004. Central vascular catheter (CVC) was established as a potential source of candidemia in 36.1%, followed by skin and soft tissues of thermal injury (22.2%) and urinary tract (8.3%). Fluconazole was used in 19 patients (52.7%) and its in vitro resistance rate was 13.9%. The overall mortality was 47.2%, and mortality related to candidemia was 30.6%. Factors associated with increased mortality were those related to severe infection and shock. CVC was the most usual focus of candidemia. Fluconazole was the most common antifungal drug administered. The management of candidemia in major burn patients is still a challenge. PMID:26931414

    Full Text Available Wound care in one of the most important prognostic factors in burn victims. Open wound carries risks for infection due to hypothermia, protein and fluid losses. In addition, unhealed wounds are the major risk factors for acute-subacute or chronic complications in burn patients. Although no exact algorithm exists for open wound treatment, early escarectomy or debridement together with grafting is the best option. Ointments together with topical epithelizing agents without dressings are genereally adequate for first-degree burns. However, topical antibacterial agents are usually required for second to third-degree wounds. Standart treatment for the open wound without epithelization is autologous skin grafting. In cases where more than 50% of the skin surface in affected, autologus donor skin may not be enough. For these cases, epidermal cell culture in vitro may be used. Mesenchymal stem cell applications which have immunosupressive effects should be utilized in cases where cells need to be prepared as allografts.

    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.

  3. Measurement of Solid Rocket Propellant Burning Rate Using X-ray Imaging

    Science.gov (United States)

    Denny, Matthew D.

    The burning rate of solid propellants can be difficult to measure for unusual burning surface geometries, but X-ray imaging can be used to measure burning rate. The objectives of this work were to measure the baseline burning rate of an electrically-controlled solid propellant (ESP) formulation with real-time X-ray radiography and to determine the uncertainty of the measurements. Two edge detection algorithms were written to track the burning surface in X-ray videos. The edge detection algorithms were informed by intensity profiles of simulated 2-D X-ray images. With a 95% confidence level, the burning rates measured by the Projected-Slope Intersection algorithm in the two combustion experiments conducted were 0.0839 in/s +/-2.86% at an average pressure of 407 psi +/-3.6% and 0.0882 in/s +/-3.04% at 410 psi +/-3.9%. The uncertainty percentages were based on the statistics of a Monte Carlo analysis on burning rate.

    Because of their extensive wounds, burn patients are chronically exposed to inflammatory mediators. Thus, burn patients, by definition, already have "systemic inflammatory response syndrome." Current definitions for sepsis and infection have many criteria (fever, tachycardia, tachypnea, leukocytosis) that are routinely found in patients with extensive burns, making these current definitions less applicable to the burn population. Experts in burn care and research, all members of the American Burn Association, were asked to review the literature and prepare a potential definition on one topic related to sepsis or infection in burn patients. On January 20, 2007, the participants met in Tucson, Arizona to develop consensus for these definitions. After review of the definitions, a summary of the proceedings was prepared. The goal of the consensus conference was to develop and publish standardized definitions for sepsis and infection-related diagnoses in the burn population. Standardized definitions will improve the capability of performing more meaningful multicenter trials among burn centers.

    Burn excision, a difficult technique owing to the training required to identify the extent and depth of injury, will benefit from a tool that can cue the surgeon as to where and how much to resect. We explored two rapid and noninvasive optical imaging techniques in their ability to identify burn tissue from the viable wound bed using an animal model of tangential burn excision. Photoplethysmography (PPG) imaging and multispectral imaging (MSI) were used to image the initial, intermediate, and final stages of burn excision of a deep partial-thickness burn. PPG imaging maps blood flow in the skin's microcirculation, and MSI collects the tissue reflectance spectrum in visible and infrared wavelengths of light to classify tissue based on a reference library. A porcine deep partial-thickness burn model was generated and serial tangential excision accomplished with an electric dermatome set to 1.0 mm depth. Excised eschar was stained with hematoxylin and eosin to determine the extent of burn remaining at each excision depth. We confirmed that the PPG imaging device showed significantly less blood flow where burn tissue was present, and the MSI method could delineate burn tissue in the wound bed from the viable wound bed. These results were confirmed independently by a histological analysis. We found these devices can identify the proper depth of excision, and their images could cue a surgeon as to the preparedness of the wound bed for grafting. These image outputs are expected to facilitate clinical judgment in the operating room.

    2016-08-20

    Burn causes bone metabolic abnormality in most cases, including the changes in osteoblasts and osteoclasts, bone mass loss, and bone absorption, which results in decreased bone mineral density. These changes are sustainable for many years after burn and even cause growth retardation in burned children. The mechanisms of bone metabolic abnormality after burn include the increasing glucocorticoids due to stress response, a variety of cytokines and inflammatory medium due to inflammatory response, vitamin D deficiency, hypoparathyroidism, and bone loss due to long-term lying in bed. This article reviews the pathogenesis and regularity of bone metabolic abnormality after burn, the relationship between bone metabolic abnormality and burn area/depth, and the treatment of bone metabolic abnormality, etc. and discusses the research directions in the future.

  18. A non-destructive surface burn detection method for ferrous metals based on acoustic emission and ensemble empirical mode decomposition: from laser simulation to grinding process

    International Nuclear Information System (INIS)

    Grinding is usually done in the final finishing of a component. As a result, the surface quality of finished products, e.g., surface roughness, hardness and residual stress, are affected by the grinding procedure. However, the lack of methods for monitoring of grinding makes it difficult to control the quality of the process. This paper focuses on the monitoring approaches for the surface burn phenomenon in grinding. A non-destructive burn detection method based on acoustic emission (AE) and ensemble empirical mode decomposition (EEMD) was proposed for this purpose. To precisely extract the AE features caused by phase transformation during burn formation, artificial burn was produced to mimic grinding burn by means of laser irradiation, since laser-induced burn involves less mechanical and electrical noise. The burn formation process was monitored by an AE sensor. The frequency band ranging from 150 to 400 kHz was believed to be related to surface burn formation in the laser irradiation process. The burn-sensitive frequency band was further used to instruct feature extraction during the grinding process based on EEMD. Linear classification results evidenced a distinct margin between samples with and without surface burn. This work provides a practical means for grinding burn detection. (paper)

    The aims and purposes of this systematic review of the international literature are to discuss and clarify some considerations on Burning Mouth Syndrome (BMS). Over the last 40 years, many researchers have addressed this disease clinically or experimentally. Thus, the etiology and pathogenesis of BMS remain unclear. We analyzed the etiopathogenesis of Burning Mouth Syndrome and of the burning oral sensation and currently, we could not find a consensus on the diagnosis and classification of BMS. Further studies are required to better understand the pathogenesis of BMS, and a "Gold Standard" classification is required because not every burning sensation in the mouth is BMS. PMID:26863819

    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

    Practice guidelines (PGs) are recommendations for diagnosis and treatment of diseases and injuries, and are designed to define optimal evaluation and management. The first PGs for burn care addressed the issues encountered in developed countries, lacking consideration for circumstances in resource-limited settings (RLS). Thus, the mission of the 2014-2016 committee established by the International Society for Burn Injury (ISBI) was to create PGs for burn care to improve the care of burn patients in both RLS and resource-abundant settings. An important component of this effort is to communicate a consensus opinion on recommendations for burn care for different aspects of burn management. An additional goal is to reduce costs by outlining effective and efficient recommendations for management of medical problems specific to burn care. These recommendations are supported by the best research evidence, as well as by expert opinion. Although our vision was the creation of clinical guidelines that could be applicable in RLS, the ISBI PGs for Burn Care have been written to address the needs of burn specialists everywhere in the world.

    Full Text Available Burns are known as one of the most common forms of injury with devastating consequences. Despite the discovery of several antiseptics, burn wound healing has still remained a challenge to modern medicine. Herbal products seem to possess moderate efficacy with no or less toxicity and are less expensive compared to synthetic drugs. Burn is a well-known disorder in Iranian Traditional Medicine (ITM. Iranian physicians have divided burns into various types based on the cause and recommended treatment for each type. According to ITM references, herbal therapy was the major treatment prescribed by Iranian physicians for burns. In the present study, seven ancient Iranian medical texts were screened for the herbs with burn healing effects along with their applied dosage forms. The medicinal herbs were listed and scored based on the frequency of their repetition. Moreover, the best scientific name that was suitable for each plant as well as surveying modern studies about their biological effects has been carried out. In our investigation eighteen plants with seven topical application categories have been obtained as the most frequent herbs for burn healing in ITM. Modern studies have revealed that these plants have shown some biological activities such as anti-inflammatory, antimicrobial and antioxidant effects which might establish the relationship between the mentioned activities and burn wound healing property. This list can provide a suitable resource for future researches in the field of burn treatment.

    Infectious consequences are still a major problem and leading cause of mortality in burn patients. Among others, aeromonads need special concern because they mimic pseudomonal infections; however, they have a more rapid progression with considerable mortality if undiagnosed promptly. Here, we present a major burn case extinguished with tap water pooled in a tank. With the possibility of aeromonal infection in mind, the patient underwent aggressive debridement with proper antibiotic medication, which resulted in a successful patient management. Aeromonads should always be kept in mind in burn cases that contacted with tanked water or soil after the burn. PMID:19692919

    Mass burning is the previously much used technology in the combustion of municipal solid waste. In mass burning, unsorted waste is burned on a grate. The Biothermal Process is a new innovative municipal solid waste treatment concept. It consists of front end treatment, the biogasification of the biofraction and the fluidized bed combustion of the combustible fraction. The objective of this work is to compare the technical, environmental and economical features of the Biothermal Process and mass burning, when constructed in Malaysia. Firstly technical descriptions of concepts are presented. Secondly three cases namely Kuala Lumpur, Perai and Johor Bahru are studied. Finally conclusions are drawn. Economic comparisons revealed that the Biothermal Process is more economical than mass burning. The investment cost far the Biothermal Process is about 30 % lower than for mass burning plant. To achieve an 8 % Return on Investment, the treatment fee for the Biothermal Process is 47-95 MYR per tonne and for mass burning 181-215 MYR per tonne depending on the case. The sensibility analysis showed that independent of the variations in feeding values, the treatment fee remains much lower in the Biothermal Process. Technical comparisons show that the Biothermal Process has the better waste reduction and recycling rate in all cases. The Biothermal Process has much better electrical efficiency in the Kuala Lumpur and Johor Bahru cases, while mass burning has slightly better electrical efficiency in the Perai case. Both concepts have postal for phased construction, but phasing increases investment costs more in mass burning. The suitability of each concept to the differences in the quality of waste depends on local conditions, and both methods have merits. The Biothermal Process produces 45-70 % lower air emissions than mass burning, and generates less traffic in Kuala Lumpur and Perai, while traffic generation is equal in the Johor Bahru case. The comparisons show that according

  8. 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.

    Burns commonly occur in children and their first aid remains inadequate despite burn prevention programmes. While scald injuries predominate, contact and flame burns remain common. Although typically less severe injuries overall than those in adults, hypertrophic scarring complicating both the burn wound and even donor sites occur more frequently in children. The heterogeneous nature of burn wounds, coupled with the difficulties associated with the early clinical assessment of burn depth, has stimulated the application of novel technologies to predict burn wound outcome. This review explores current best practice in the management of paediatric burns, with a focus on prevention, optimal first aid, resuscitation, burn wound prediction and wound management strategies.

    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.

    Introduction The world-wide occurrence of burn injuries remains high despite efforts to reduce injury incidence through public awareness campaigns and improvements in living conditions. In 2004, almost 11 million people experienced burns severe enough to warrant medical treatment. Advances over the past several decades in aggressive resuscitation, nutrition, excision, and grafting have reduced morbidity and mortality. Incorporation of pharmacotherapeutics into treatment regimens may further reduce complications of severe burn injuries. Areas covered Severe burn injuries, as well as other forms of stress and trauma, trigger a hypermetabolic response that, if left untreated, impedes recovery. In the past two decades, use of anabolic agents, beta adrenergic receptor antagonists, and anti-hyperglycemic agents has successfully counteracted post-burn morbidities including catabolism, the catecholamine-mediated response, and insulin resistance. Here we review the most up-to-date information on currently used pharmacotherapies in the treatment of these sequelae of severe burns and the insights that have expanded our understanding of the pathophysiology of severe burns. Expert opinion Existing drugs offer promising advances in the care of burn injuries. Continued gains in our understanding of the molecular mechanisms driving the hypermetabolic response will enable the application of additional existing drugs to be broadened to further attenuate the hypermetabolic response.

    Full Text Available 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  0.05, but a significant increased incidence of multi organ failure, p < 0.05. These clinical outcomes were associated with a delayed hypermetabolic response, increased hyperglycemic and hyperlipidemic responses, inversed inflammatory response, immune-compromisation and substantial delay in wound healing predominantly due to alteration in characteristics of progenitor cells, p < 0.05. In summary, 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.

Necrotic tissues in some deep burn wounds are difficult to judge correctly and remove thoroughly. An electrically burned blood vessel looks “intact” but can easily break. Necrotic tissue or injured blood vessels when using NPWT are dangerous, both for causing sepsis and hemorrhage. This is the first article that reports the severe complications of NPWT in burned patients. It is imperative to heed indications and avoid contraindications. Proper preparation of wound beds, close observation, and sufficient irrigation are also crucial to avoid these severe complications, and there is an urgent need to substitute the central vacuum system with the low-pressure system.Keywords: negative pressure wound therapy, complication, burn sepsis, bleeding, drainage

    Full Text Available 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 with simple but vision saving steps and is continued with complicated surgical procedures later in the course of the disease. The goal of treatment is to restore the normal ocular surface anatomy and function. Limbal stem cell transplantation, amniotic membrane transplantation, and ultimately keratoprosthesis may be indicated depending on the patients’ needs.

    dimensions, rotation velocity, temperature, gas composition, heat transfer phenomena, etc. These conditions can only be partly simulated in ordinary lab-scale experiments. Thus, the objectives of this project have been to establish test equipment to simulate the industrial clinker burning process......The industrial cement process is subject to several changes in order to reduce the high energy consumption and thereby increase the profitability of cement production. These changes also affect the core of the entire cement producing process: the clinker formation in the rotary kiln. Thus, in order...... to maintain or even improve clinker quality (and output), we need a better understanding of the development of clinker properties inside the kiln to react upon the impact of process changes. Clinker formation in industrial rotary kilns is very complex due to a vast number of interacting parameters: kiln...

    This paper demonstrates the successful application of CFD to modeling an external burning flowfield. The study used the 2D, 3D, and PNS versions of the SPARK code. Various grids, boundary conditions, and ignition methodologies have been employed. Flameholding was achieved through the use of a subsonic outflow condition and a hot block located behind the step to ignite the fuel. Since the resulting burning produces a large subsonic region downstream of the cowl, this entire surface can be pressurized to the level of the back pressure. An evaluation of interactions between the ramjet exhaust and the external burning products demonstrate the complexity of this design issue. Ths code is now capable of evaluating the external burning effectiveness for flight vehicles using simple injector schemes, and the methodology can be readily applied to other external burning designs.

  8. Modern trends in fluid therapy for burns.

    The majority of burn centres use the crystalloid-based Parkland formula to guide fluid therapy, but patients actually receive far more fluid than the formula predicts. Resuscitation with large volumes of crystalloid has numerous adverse consequences, including worsening of burn oedema, conversion of superficial into deep burns, and compartment syndromes. Resuscitation fluids influence the inflammatory response to burns in different ways and it may be possible, therefore to affect this response using the appropriate fluid, at the appropriate time. Starches are effective volume expanders and early use of newer formulations may limit resuscitation requirements and burn oedema by reducing inflammation and capillary leak. Advanced endpoint monitoring may guide clinicians in when to 'turn off' aggressive fluid therapy and therefore avoid the problems of over-resuscitation.

    2007-03-01

    This study examined the relationship between coping strategies, anxiety and depression levels and burn injury characteristics in the early phase of the treatment in burn-injured patients. Seventy patients with severe burns were interviewed within two weeks of their burn trauma. Coping strategies were measured by the coping with burns questionnaire (CBQ). Anxiety and depression levels were assessed with the Beck Depression Inventory and the Beck Anxiety Inventory. There were no statistically significant gender differences in various coping strategies. Avoidance was associated with higher levels of anxiety, depression and hopelessness. The percentage of total body surface area (TBSA) and localization of burns were not associated with coping patterns. Implications for the assessment and management of burn injured patients were discussed.

    Objective Characterizing burn sizes that are associated with an increased risk of mortality and morbidity is critical because it would allow identifying patients who might derive the greatest benefit from individualized, experimental, or innovative therapies. Although scores have been established to predict mortality, few data addressing other outcomes exist. The objective of this study was to determine burn sizes that are associated with increased mortality and morbidity after burn. Design and Patients Burn patients were prospectively enrolled as part of the multicenter prospective cohort study, Inflammation and the Host Response to Injury Glue Grant, with the following inclusion criteria: 0–99 years of age, admission within 96 hours after injury, and >20% total body surface area burns requiring at least one surgical intervention. Setting Six major burn centers in North America. Measurements and Main Results Burn size cutoff values were determined for mortality, burn wound infection (at least two infections), sepsis (as defined by ABA sepsis criteria), pneumonia, acute respiratory distress syndrome, and multiple organ failure (DENVER2 score >3) for both children (<16 years) and adults (16–65 years). Five-hundred seventy-three patients were enrolled, of which 226 patients were children. Twenty-three patients were older than 65 years and were excluded from the cutoff analysis. In children, the cutoff burn size for mortality, sepsis, infection, and multiple organ failure was approximately 60% total body surface area burned. In adults, the cutoff for these outcomes was lower, at approximately 40% total body surface area burned. Conclusions In the modern burn care setting, adults with over 40% total body surface area burned and children with over 60% total body surface area burned are at high risk for morbidity and mortality, even in highly specialized centers.

    Crop residue burning leads to atmospheric pollution and is an enormous waste of crop residue resource. Crop residue burning can be monitored timely in large regions as the fire points can be recognized through remotely sensed image via thermal infrared bands. However, the area, the detailed distribution pattern and especially the severity of the burning areas cannot be derived only by the thermal remote sensing approach. The burning index, which was calculated with two or more spectral bands at where the burned and unburned areas have distinct spectral characteristics, is widely used in the forest fire investigation. However its potential application for crop residue burning evaluation has not been explored. With two Landsat 8 images that cover a part of the Songnen Plain, three burning indices, i.e., the normalized burned ratio (NBR), the normalized burned ratio incorporating the thermal band (NBRT), and the burned area index (BAI), were used to classify the crop residue burned and unburned areas. The overall classification accuracies were 91.9%, 92.3%, and 87.8%, respectively. The correlation analysis between the indices and the crop residue coverage indicated that the NBR and NBRT were positively correlated with the crop residue coverage (R2 = 0.73 and 0.64, respectively) with linear regression models, while the BAI was exponentially correlated with the crop residue coverage (R2 = 0.68). The results indicated that the use of burning indices in crop residue burning monitoring could quantify crop residue burning severity and provide valuable data for evaluating atmospheric pollution.

    Elderly burn care represents a vast challenge. The elderly are one of the most susceptible populations to burn injuries, but also one of the fastest growing demographics, indicating a substantial increase in patient numbers in the near future. Despite the need and importance of elderly burn care, survival of elderly burn patients is poor. Additionally, little is known about the responses of elderly patients after burn. One central question that has not been answered is what age defines an elderly patient. The current study was conducted to determine whether there is a cut-off age for elderly burn patients that is correlated with an increased risk for mortality and to determine the burn size in modern burn care that is associated with increased mortality. To answer these questions, we applied appropriate statistical analyses to the Ross Tilley Burn Centre and the Inflammatory and Host Response to Injury databases. We could not find a clear cut-off age that differentiates or predicts between survival and death. Risk of death increased linearly with increasing age. Additionally, we found that the LD50 decreases from 45% total body surface area (TBSA) to 25% TBSA from the age of 55 years to the age of 70 years, indicating that even small burns lead to poor outcome in the elderly. We therefore concluded that age is not an ideal to predictor of burn outcome, but we strongly suggest that burn care providers be aware that if an elderly patient sustains even a 25% TBSA burn, the risk of mortality is 50% despite the implementation of modern protocolized burn care.

  19. Reactive burn models and ignition & growth concept

    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.

    In this paper coke remaining from the partial burning of coke deposited during the commercial re-forming of naphtha on a Pt-Re/Al[sub 2]O[sub 3] catalyst is studied. Burning temperatures are 623-923 K, and the remaining coke is characterized by temperature-programmed oxidation, X-ray diffraction, electron diffraction, IR, [sup 13]C CP-MAS NMR, electron spectroscopy for chemical analysis, electron paramagnetic resonance, and chemical analysis. After coke is burned at 673 K, the residual coke shows the minimum value in the H/C ratio and the maximum in the thickness of the aromatic layers, degree of organization, C==O concentration, binding energy of C 1s, peak width, and g value. This agrees with the model of coke burning: at low temperatures, the burning is selective; the more hydrogenated and amorphous carbonaceous species are burnt first. At high temperatures, the burning is nonselective and all species are simultaneously burnt. Coke is partially oxidized during burning, and intermediate species with C==O and C--OH groups are formed.

    Full Text Available Objective: The increase in life quality and expectancy causes an increase in the elderly population. Improvements in burn treatment resulted in decreased mortality in children and young adults but in elderly patients burns are still an important trauma that should be handed differently than other age groups. The aim of this study was to evaluate the factors effecting mortality in patients with burns over 45 years old. Methods: Fifty-eight patients over 45 years of age, who were treated in our burns unit in the last 3 years were included in our study. Their age, burn percentage and depth, coexisting diseases and mortality rates were examined retrospectively. Results: The average age of surviving patients was 57.4 years while it was 70 years for nonsurviving patients (p=0.002. The width of burn area was 21.1 % in surviving and 50 % in nonsurviving patients (p<0.01. The effect of additional coexistent diseases on mortality was significant (p=0.001. The most common reasons of mortality were sepsis and congestive heart failure. Conclusion: We found out that the age, percentage of burns and coexistent diseases had a negative effect on success of treatment and mortality. Mortality rates will decrease in these cases with careful follow-up and a multidisciplinary approach. J Clin Exp Invest 2015; 6 (3: 240-243

    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.

  5. Infections in critically ill burn patients.

    2016-04-01

    Severe burn patients are one subset of critically patients in which the burn injury increases the risk of infection, systemic inflammatory response and sepsis. The infections are usually related to devices and to the burn wound. Most infections, as in other critically ill patients, are preceded by colonization of the digestive tract and the preventative measures include selective digestive decontamination and hygienic measures. Early excision of deep burn wound and appropriate use of topical antimicrobials and dressings are considered of paramount importance in the treatment of burns. Severe burn patients usually have some level of systemic inflammation. The difficulty to differentiate inflammation from sepsis is relevant since therapy differs between patients with and those without sepsis. The delay in prescribing antimicrobials increases morbidity and mortality. Moreover, the widespread use of antibiotics for all such patients is likely to increase antibiotic resistance, and costs. Unfortunately the clinical usefulness of biomarkers for differential diagnosis between inflammation and sepsis has not been yet properly evaluated. Severe burn injury induces physiological response that significantly alters drug pharmacokinetics and pharmacodynamics. These alterations impact antimicrobials distribution and excretion. Nevertheless the current available literature shows that there is a paucity of information to support routine dose recommendations.

    In-situ burning is considered to be a viable means to clean oil spills on water. In-situ burning, when performed under the right conditions, can reduce the volume of spilled oil and eliminate the need to collect, store, transport and dispose of the recovered oil. This paper presented the results of bench-scale in-situ burning tests in which Bunker C, Orimulsion and weathered bitumen were burned outdoors during the winter in burn pans of approximately 1 square metre. Each test was conducted on salt water which caused the separation of the bitumen from the water in the Orimulsion. Small amounts of diesel fuel was used to ignite the heavy oils. Quantitative removal of the fuels was achieved in all cases, but re-ignition was required for the Orimulsion. Maximum efficiency was in the order of 70 per cent. The residue was mostly asphaltenes and resins which cooled to a solid, glass like material that could be readily removed. The study showed that the type of oil burned influences the behaviour of the burns. Bunker C burned quite well and Orimulsion burned efficiently, but re-ignition was necessary. It was concluded that there is potential for burning heavy oils of several types in-situ. 6 refs., 7 tabs., 18 figs.

Reports of bony ankylosis following thermal and electrical injury are limited.Design and patients. Thirteen cases of burn-related joint ankylosis in four patients are presented.Conclusion. Patients with burns from thermal or electrical injury may develop bony ankylosis among other radiographic manifestations. This bony ankylosis may result either from bridging extra-articular heterotopic ossification with preservation of the underlying joint or from intra-articular fusion due to joint destruction.

    Full Text Available Background: Burns injuries are recognized as a major health problem worldwide. In children and, particularly, in our environment where poverty, ignorance and disease are still high, they constitute significant morbidity and mortality. Previous studies on this topic in parts of Nigeria either lumped adults and children together or were retrospective. We, therefore, prospectively studied the current trends in burns in children. Patients and Methods: This prospective study of burns spanned over a period of 18 months (June 2006-December 2007 at the Paediatric Surgery Units of the Imo State University Teaching Hospital, Orlu, and the Federal Medical Centre, Owerri, Imo State. Data were collected and analysed for age, sex, cause/type of burn, place of burn, presence or absence of adult/s, initial prehospital intervention, interval between injury and presentation, surface area and depth of burn and treatment and outcome. Results: Fifty-three patients were studied, 31 (58.4% were male and 22 (41.6% were female (M:F = 1.4:1. Patients mostly affected were aged 2 years and below. The most common cause of burns was hot water in 31 (58.5% patients. The vast majority of these injuries happened in a domestic environment (92.5% and in the presence of competent adult/s (88.7%. Outcome of treatment was good: there were two (3.8% deaths and 46 (86% patients had complete recovery. Conclusion: Burns is still a major health problem among children in south eastern Nigeria. Fortunately, outcome of appropriate treatment is good. However, we think that poor safety consciousness among parents is a major predisposing factor. Public enlightenment on measures to ensure safe home environment may be necessary to avoid or limit childhood burns.

    This study describes the ultrasound assessment of burn scars in paediatric patients and the association of these scar thickness with laser Doppler imaging (LDI) determined burn depth. A total of 60 ultrasound scar assessments were conducted on 33 scars from 21 paediatric burn patients at 3, 6 and 9 months after-burn. The mean of peak scar thickness was 0.39±0.032 cm, with the thickest at 6 months (0.40±0.036 cm). There were 17 scald burn scars (0.34±0.045 cm), 4 contact burn scars (0.61±0.092 cm), and 10 flame burn scars (0.42±0.058 cm). Each group of scars followed normal distributions. Twenty-three scars had original burns successfully scanned by LDI and various depths of burns were presented by different colours according to blood perfusion units (PU), with dark blue burns, with the thinnest scars for green coloured burns and the thickest for dark blue coloured burns. Within light blue burns, grafted burns healed with significantly thinner scars than non-grafted burns. This study indicates that LDI can be used for predicting the risk of hypertrophic scarring and for guiding burn care. To our knowledge, this is the first study to correlate the thickness of burns scars by ultrasound scan with burn depth determined by LDI.

On the 1st day, patients and nurses submitted baseline VAS ratings. Before the next day's would debridement, Ss received hypnosis, attention and information, or no treatment. Only hypnotized Ss reported significant pain reductions relative to pretreatment baseline. This result was corroborated by nurse VAS ratings. Findings indicate that hypnosis is a viable adjunct treatment for burn pain. Theoretical and practical implications and future research directions are discussed. PMID:1383302

    Major burn injury is one of the most serious and often life-threatening forms of trauma. Burn patients not only suffer from the physical, psychological, social and spiritual impacts of their injury but also experience considerable changes in health-related quality of life. This paper presents a review of the literature on the implications of previous research and clinical care guidelines related to major burn injuries in order to help clinical practice nurses use evidence-based care guidelines to respond to initial injury assessments, better manage the complex systemic response to these injuries, and provide specialist wound care, emotional support, and rehabilitation services.

    Erosive burning is a common burning phenomenon of the gunpowder with inner holes. The actual combustion law of the gunpowder with inner holes can be changed by erosive burning. Pressure difference between the inner and the outer of hole caused by loading density variation of the propellant charge makes erosive burning occur at inner holes during in-bore burning. The effect of erosive burning on burning speed of the propellant is studied by using the effects of flow rate, heat transfer and erosion of the combustion gas in inner holes on burning rate. The mathematic model of erosive burning of the propellant is established. The effects of the factors such as loading density, inner hole size and grain length on erosive burning and interior ballistic performance are analyzed .The method to improve the bore pressure for small charge mass and small firing range by erosive burning is proposed.

    describes the inherent resistance of soil to erosion. Hillslope erosion models typically consider erodibility to be constant with depth. This may not be the case after wildfire because erodibility is partly determined by the availability of noncohesive soil and ash at the surface. This study quantifies erodibility of burned soils using methods that explicitly capture variations in soil properties with depth. Flume experiments on intact cores from three sites in western United States showed that erodibility of fire-affected soil was highest at the soil surface and declined exponentially within the top 20 mm of the soil profile, with root density and soil depth accounting for 62% of the variation. Variation in erodibility with depth resulted in transient sediment flux during erosion experiments on bounded field plots. Material that contributed to transient flux was conceptualized as a layer of noncohesive material of variable depth (dnc). This depth was related to shear strength measurements and sampled spatially to obtain the probability distribution of noncohesive material as a function of depth below the surface. After wildfire in southeast Australia, the initial dnc ranged from 7.5 to 9.1 mm, which equated to 97-117 Mg ha-1 of noncohesive material. The depth decreased exponentially with time since wildfire to 0.4 mm (or < 5 Mg ha-1) after 3 years of recovery. The results are organized into a framework for modeling fire effects on erodibility as a function of the production and depletion of the noncohesive layer overlying a cohesive layer.

  14. Simulation of burning tokamak plasmas

    International Nuclear Information System (INIS)

    To simulate dynamical behaviour of tokamak fusion reactors, a zero-dimensional time-dependent particle and power balance code has been developed. The zero-dimensional plasma model is based on particle and power balance equations that have been integrated over the plasma volume using prescribed profiles for plasma parameters. Therefore, the zero-dimensional model describes the global dynamics of a fusion reactor. The zero-dimensional model has been applied to study reactor start-up, and plasma responses to changes in the plasma confinement, fuelling rate, and impurity concentration, as well as to study burn control via fuelling modulation. Predictions from the zero-dimensional code have been compared with experimental data and with transport calculations of a higher dimensionality. In all cases, a good agreement was found. The advantage of the zero-dimensional code, as compared to higher-dimensional transport codes, is the possibility to quickly scan the interdependencies between reactor parameters.

    Gas lantern mantles contain thorium to produce incandescence when lantern fuel is burned on the mantle. Although only thorium is initially present on the mantle, the thorium daughters build up, some over a period of weeks and some over a period of years, and significant quantities of these daughters are present when the mantle is used. Some of these daughters are released when the lantern fuel is burned on the mantle. The amounts of radioactivity released during burning is studied by measuring the gamma radiation emitted by the daughters. Results of this study show that some of the radium (224Ra and 228Ra) and more than half the 212Pb and 212Bi is released during the first hour of a burn. The actual amounts release depend on the age of the mantle.

  17. Nutrition and Metabolic Support in Burn

    2011-07-01

    Full Text Available Burn injury results in a dramatic increase of the basal metabolic rate. Severe burn injury nearly doubles resting energy expenditure and hypermetabolism associated with burn results in a loss of body fat stores and a loss of visceral and structural protein mass. The clinical effects of these changes include immunosuppression, delayed wound healing, and generalized muscle weakness. Post burn, the metabolic and catabolic responses are prolonged in severity and time course, lasting weeks to months in contrast to the days and weeks observed in other injuries. Nutrition support provides the substrates and nutrients to prevent the complications of deficiencies as well as supporting wound healing, and recovery from hormonal and metabolic abnormalities after thermal injury.

    2016-06-01

    Burning something, (e.g. the proverbial lump of coal, or an encyclopaedia for that matter), in a blackbody furnace leads to an approximately Planck emission spectrum with an average entropy/information transfer of approximately 3.9 ± 2.5 bits per emitted photon. This quantitative and qualitative result depends only on the underlying unitarity of the quantum physics of burning, combined with the statistical mechanics of blackbody radiation. The fact that the utterly standard and unitarity preserving process of burning something (in fact, burning anything) nevertheless has an associated entropy/information budget, and the quantitative size of that entropy/information budget, is a severely under-appreciated feature of standard quantum statistical physics.

    A 6-segment subscale motor was developed to generate a range of internal environments from which multiple propellants could be characterized for erosive burning. The motor test bed was designed to provide a high Mach number, high mass flux environment. Propellant regression rates were monitored for each segment utilizing ultrasonic measurement techniques. These data were obtained for three propellants RSRM, ETM- 03, and Castor@ IVA, which span two propellant types, PBAN (polybutadiene acrylonitrile) and HTPB (hydroxyl terminated polybutadiene). The characterization of these propellants indicates a remarkably similar erosive burning response to the induced flow environment. Propellant burnrates for each type had a conventional response with respect to pressure up to a bulk flow velocity threshold. Each propellant, however, had a unique threshold at which it would experience an increase in observed propellant burn rate. Above the observed threshold each propellant again demonstrated a similar enhanced burn rate response corresponding to the local flow environment.

    Background Burn injury is a dramatic event with acute and chronic consequences including insulin resistance. However, factors associated with insulin resistance have not been previously investigated. Purpose To identify factors associated with long-term insulin resistance in pediatric burn injury survivors. Methods The study sample consisted of 61 pediatric burn injury survivors 24 to 36 months after the burn injury, who underwent an oral glucose tolerance test. To assess insulin resistance, we calculated the area under the curve for glucose and insulin. The diagnostic criteria of the American Diabetes Association were used to define individuals with impaired glucose metabolism. Additional data collected include body composition, anthropometric measurements, burn characteristics and demographic information. The data were analyzed using multivariate linear regression analysis. Results Approximately 12% of the patients met the criteria for impaired glucose metabolism. After adjusting for possible confounders, burn size, age and percent body fat were associated with the area under the curve for glucose (p<0.05 for all). Time post-burn and lean mass were inversely associated with the area under the curve for glucose (p<0.05 for both). Similarly, older age predicted higher insulin area under the curve. Conclusion A significant proportion of pediatric injury survivors suffer from glucose abnormalities 24–36 months post-burn. Burn size, time post-burn, age, lean mass and adiposity are significant predictors of insulin resistance in pediatric burn injury survivors. Clinical evaluation and screening for abnormal glucose metabolism should be emphasized in patients with large burns, older age and survivors with high body fat. PMID:24918945

We retrospectively reviewed the characteristics and multiple organ dysfunction syndrome (MODS patterns of burn deaths in our center from January 2003 to December 2009. The mortality rate during this time period was 2.3%. Fifty-six patients died, including 49 males and 7 females. The mean survival time was 28.45 ± 24.60 days. The burn percentage was (76.70 ± 26.86 % total burn surface area (TBSA, with (27.74 ± 24.95 % deep-partial thickness burns and (46.88 ± 33.84 % full-thickness burns. Inhalation injury was diagnosed in 36 (64.29% patients. Patients who had undergone an operation, particularly in the first week post-burn, had a significantly longer survival time. An average of 5.50 ± 1.35 malfunctioning organs per patient and a mean sequential organ failure assessment (SOFA score of 13.91 ± 3.65 were observed. The most frequently malfunctioning organs were involved in the respiratory, hematologic, circulatory, and central nervous systems. Most of the organ damage occurred during the first week post-burn, followed by 4 weeks later, with relatively less organ damage observed in the third week. Among patients with a TBSA over 50%, non-survivors had larger burn sizes (particularly larger full-thickness burns and a higher incidence of inhalation injury compared with survivors; non-survivors were also more likely to have microorganism-positive blood and sputum cultures. In conclusion, burn deaths are related to a higher burn percentage, inhalation injury, MODS, and infection. Early operation may help improve survival duration.

    Full Text Available Introduction: The skin protects against fluid and electrolyte loss. Burn injury does affect skin integrity and protection against fluid loss is lost. Thus, a systemic dehydration can be provoked by underestimation of fluid loss through burn wounds. Purpose: We wanted to quantify transdermal fluid loss in burn wounds. Method: Retrospective study. 40 patients admitted to a specialized burn unit were analyzed and separated in two groups without (Group A or with (Group B hypernatremia. Means of daily infusion-diuresis-ratio (IDR and the relationship to totally burned surface area (TBSA were analyzed. Results: In Group A 25 patients with a mean age of 47±18 years, a mean TBSA of 23±11%, and a mean abbreviated burned severity index (ABSI score of 6.9±2.1 were summarized. In Group B 15 patients with a mean age of 47±22 years, a mean TBSA of 30±13%, and a mean ABSI score of 8.1±1.7 were included. Statistical analysis of the period from day 3 to day 6 showed a significant higher daily IDR-amount in Group A (Group A vs. Group B: 786±1029 ml vs. –181±1021 ml; p<0.001 and for daily IDR-TBSA-ratio (Group A vs. Group B: 40±41 ml/% vs. –4±36 ml/%; p<0.001. Conclusions: There is a systemic relevant transdermal fluid loss in burn wounds after severe burn injury. Serum sodium concentration can be used to calculate need of fluid resuscitation for fluid maintenance. There is a need of an established fluid removal strategy to avoid water and electrolyte imbalances.

  14. Disseminated intravascular coagulation in burn injury.

    Science.gov (United States)

    Lippi, Giuseppe; Ippolito, Luigi; Cervellin, Gianfranco

    2010-06-01

    Disseminated intravascular coagulation (DIC) is a complex and multifaceted disorder characterized by the activation of coagulation and fibrinolytic pathways, consumption of coagulation factors, and depletion of coagulation regulatory proteins. The introduction into the circulation of cellular debris characterized by strong thromboplastic activity due to tissue factor exposition or release (in or from burned tissues), which can thereby activate extrinsic pathway of coagulation system and trigger massive thrombin generation when present in sufficient concentration, represents the most plausible biological explanation to support the development of intravascular coagulation in patients with burn injury. Severe burns left untreated might also lead to an immunological and inflammatory response (activation of the complement cascade), which can amplify fibrinolysis and blood clotting. Overall, the real prevalence of DIC in patients with burns is as yet unclear. Postmortem, retrospective, and even longitudinal investigations are in fact biased by several factors, such as the objective difficulty to establish whether DIC might have occurred as a primary complication of burns or rather as a consequence of other superimposed pathologies (e.g., sepsis, multiple organ failure), the different diagnostic criteria for assessing DIC, and the heterogeneity of the patient samples studied. Nevertheless, the current scientific evidence is consistent with the hypothesis that biochemical changes suggestive for DIC (hypercoagulability, hypo- and hyperfibrinolysis) are commonplace in patients with burn trauma, and their severity increases exponentially with the severity of injury. Overt DIC seems to occur especially in critically ill burn patients or in those with severe burns (up to third degree) and large involvement of body surface area, in whom an appropriate therapy might be effective to prevent the otherwise fulminant course. Although early prophylaxis with antithrombin concentrates

    Burn injury is considered by children as one of the most painful traumas (just after bone factures). Burn pain in children can and must be controlled as well as for adult patients, with almost identical techniques. Continuous pain from injury and intermittent pain caused by therapeutic procedures must be evaluated and treated separately. Due to very high levels of nociception, satisfactory management of procedural pain requires the use of opioid therapy. Non pharmacological methods are meaningless if pharmacological treatment is not optimal.

    In addition to recent advances in burn patient care techniques such as maintaining warm circumambient temperature, the early excision of wounds, and the use of closed dressing, providing nutrition support through early feeding has proven instrumental in greatly increasing the survival rate of burn patients. Severe burns complicated by many factors initiate tremendous physiological stress that leads to postburn hypermetabolism that includes enhanced tissue catabolism, the loss of muscle mass, and decreases in the body's reservoirs of protein and energy. These problems have become the focus of burn therapy. Treating severe burns aims not only to enhance survival rates but also to restore normal bodily functions as completely as possible. Recent research evaluating the application of anabolic agents and immune-enhance formula for severe burns therapy has generated significant controversy. Inadequate caloric intake is one of the main differences among the related studies, with the effect of many special nutrients such as bran acid amides not taken into consideration. Therefore, considering the sufficiency of caloric and protein intake is critical in assessing effectiveness. Only after patients receive adequate calories and protein may the effect of special nutrients such as glutamine and supplements be evaluated effectively. PMID:26813059

    The advent of widely available nanoscale energetic composites has resulted in a flurry of novel applications. One of these applications is the use of nanomaterials in energetic compositions. In compositions that exhibit high sensitivity to stimulus, these materials are often termed metastable intermolecular composites (MIC). More generally, these compositions are simply called nanoenergetics. Researchers have used many different experimental techniques to analyze the various properties of nanoenergetic systems. Among these various techniques, the confined tube burn is a simple experiment that is capable of obtaining much data related to the combustion of these materials. The purpose of this report is to review the current state of the confined tube burn experiment, including the drawbacks of the technique and possible remedies. As this report is intended to focus on the specific experimental technique, data from many different energetic materials, and experimental configurations will be presented. The qualitative and quantitative data that can be gathered using confined tube burn experiments include burning rates, total impulse, pressure rise rate, and burning rate differences between different detector types. All of these measurements lend insight into the combustion properties and mechanisms of specific nanoenergetics. Finally, certain data indicates a more complicated flow scenario which may need to be considered when developing burn tube models.

    Climate change has a significant impact on the lives of Canadians and their economies. In northern British Columbia, the ability to grow, process and transport food will likely change. The rising cost of fuel and other natural resources will create a need for more resilient communities. This report presented a community energy plan for Burns Lake in order to provide the first steps toward building on an already resilient community. The report answered questions about Burns Lake's energy consumption and greenhouse gas (GHG) emissions as well as the community's views on energy issues. The report provided background information on the Village of Burns Lake and discussed climate change in Burns Lake, energy use, and greenhouse gas emissions. The report also described community engagement by way of a questionnaire on fuel prices, homes and public opinion in Burns Lake. A strategy was also outlined. It was concluded that the village of Burns Lake is well positioned to face challenges regarding future energy use.

    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 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.

    Full Text Available Burns are an important cause of injury to young children, being the third most frequent cause of injury resulting in death behind motor vehicle accidents and drowning. Burn injuries account for the greatest length of stay of all hospital admissions for injuries and costs associated with care are substantial. The majority of burn injuries in children are scald injuries resulting from hot liquids, occurring most commonly in children aged 0-4 years. Other types of burns include electrical, chemical and intentional injury. Mechanisms of injury are often unique to children and involve exploratory behavior without the requisite comprehension of the dangers in their environment. Assessment of the burnt child includes airway, breathing and circulation stabilization, followed by assessment of the extent of the burn and head to toe examination. The standard rule of 9s for estimating total body surface area (TBSA of the burn is inaccurate for the pediatric population and modifications include utilizing the Lund and Browder chart, or the child’s palm to represent 1% TBSA. Further monitoring may include cardiac assessment, indwelling catheter insertion and evaluation of inhalation injury with or without intubation depending on the context of the injury. Risk factors and features of intentional injury should be known and sought and vital clues can be found in the history, physical examination and common patterns of presentation. Contemporary burn management is underscored by several decades of advancing medical and surgical care however, common to all injuries, it is in the area of prevention that the greatest potential to reduce the burden of these devastating occurrences exists.

    Full Text Available Burning is one of the commonest causes of death. Due to the high rate of death among burn victims epidemiological investigation of burning, burning agents and the relevant motivations can be of great preventive value.1 In this cross-sectional study all the hospitalized patients in Shahid Motahari Burn Hospital at Tehran city in the year 2009 were included in the study. The collected data were analyzed by SPSS (ver. 17 software. Out of the 1548 hospitalized patients for burn, 1134 (73.3% left hospital in good conditions, 47 (3% left in relatively good conditions, 289 (18.7% died and 78 (5% persons left the Hospital satisfactorily on their own volition. About two-thirds of the patients were men. The mean age of the burn victims was 27.9±18.3 years, 16% of them being 5 years old or younger. The highest percentage of burn area was 30% of the total body surface which was seen in 20 to 30-year old patients. 58.7% of burns had been caused by fire. 94% of the burns had happened accidentally, 5% by suicidal and 1% by homicidal acts. The highest percentage of burn was observed in patients in whom the burn agent was fire. Six (4% persons had first degree, 820 (53% persons had second degree and 722 (46.6% had third degree burns. In patients who had committed suicide third degree burns were higher than second degree burns (7.7% vs. 2%. 24.4% of women and 16.6% of men died due to the burns. The rate of death in patients less than 50 years of age was 18% but the figure increased to 24% in those above 50. A burn area less than or more than 10% was, respectively correlated with 2.1% and 22.1% of deaths. 34.8% of the patients with third degree burns and 4.6% of those with second and first degree burns died. 58.3% of the suicidal patient died due to the severity of the burns relative to 16.7% due to other causes. 89 (5.7% patients had respiratory tract burns and the death rate was 58.4% among these patients while the death rate was 16.2% in patients without

    The objective of this work is to quantitatively investigate the dripping-burning and flowing fire of thermoplastics. A new experimental setup is developed with a heating vessel and a T-trough. Hot thermoplastic liquids are generated in the vessel by electric heating. N2 gas is continuously injected into the vessel to avoid a sudden ignition of fuel in it. The detailed flowing burning behaviors of pool fire in the T-trough are analyzed through the measurements of the mass, heat flux and temperatures etc. The experimental results suggest that a continuous dripping of melted thermoplastic liquids in a nearly constant mass rate can be successfully made in the new setup. It also shows that the mass dripping rate of melted PS liquid is smaller than PP and PE since its large viscosity. In addition, the flame spread velocities of hot liquids of PS in the T-trough are also smaller than that of PP and PE because of its large viscosity. The mass burning rate of the PP and PE pool fire in T-trough are smaller than PS. Finally, considering the heating, melting, dripping and flowing burning behaviors of these polymers, it is suggested that the fire hazard of PE and PP are obviously higher than PS for their faster flowing burning.

    2016-01-01

    An approach for managing Orion on-orbit burn execution is described for nominal and failure response scenarios. The burn management strategy for Orion takes into account per-burn variations in targeting, timing, and execution; crew and ground operator intervention and overrides; defined burn failure triggers and responses; and corresponding on-board software sequencing functionality. Burn-to- burn variations are managed through the identification of specific parameters that may be updated for each progressive burn. Failure triggers and automatic responses during the burn timeframe are defined to provide safety for the crew in the case of vehicle failures, along with override capabilities to ensure operational control of the vehicle. On-board sequencing software provides the timeline coordination for performing the required activities related to targeting, burn execution, and responding to burn failures.

  9. Skin Burns Degree Determined by Computer Image Processing Method

    Science.gov (United States)

    Li, Hong-yan

    In this paper a new method determining the degree of skin burns in quantities is put forward. Firstly, with Photoshop9.0 software, we analyzed the statistical character of skin burns images' histogram, and then turned the images of burned skins from RGB color space to HSV space, to analyze the transformed color histogram. Lastly through Photoshop9.0 software we get the percentage of the skin burns area. We made the mean of images' histogram,the standard deviation of color maps,and the percentage of burned areas as indicators of evaluating burns,then distributed indicators the weighted values,at last get the burned scores by summing the products of every indicator of the burns and the weighted values. From the classification of burned scores, the degree of burns can be evaluated.

  10. Ceruloplasmin and Hypoferremia: Studies in Burn and Non-Burn Trauma Patients

    Directory of Open Access Journals (Sweden)

    Michael A. Dubick

    2015-03-01

    Full Text Available Objective: Normal iron handling appears to be disrupted in critically ill patients leading to hypoferremia that may contribute to systemic inflammation. Ceruloplasmin (Cp, an acute phase reactant protein that can convert ferrous iron to its less reactive ferric form facilitating binding to ferritin, has ferroxidase activity that is important to iron handling. Genetic absence of Cp decreases iron export resulting in iron accumulation in many organs. The objective of this study was to characterize iron metabolism and Cp activity in burn and non-burn trauma patients to determine if changes in Cp activity are a potential contributor to the observed hypoferremia. Material and Methods: Under Brooke Army Medical Center Institutional Review Board approved protocols, serum or plasma was collected from burn and non-burn trauma patients on admission to the ICU and at times up to 14 days and measured for indices of iron status, Cp protein and oxidase activity and cytokines. Results: Burn patients showed evidence of anemia and normal or elevated ferritin levels. Plasma Cp oxidase activity in burn and trauma patients were markedly lower than controls on admission and increased to control levels by day 3, particularly in burn patients. Plasma cytokines were elevated throughout the 14 days study along with evidence of an oxidative stress. No significant differences in soluble transferrin receptor were noted among groups on admission, but levels in burn patients were lower than controls for the first 5 days after injury. Conclusion: This study further established the hypoferremia and inflammation associated with burns and trauma. To our knowledge, this is the first study to show an early decrease in Cp oxidase activity in burn and non-burn trauma patients. The results support the hypothesis that transient loss of Cp activity contributes to hypoferremia and inflammation. Further studies are warranted to determine if decreased Cp activity increases the risk of

    Fire has played a major role in mankind's life from the beginning. Used for heating and cooking, its various uses have evolved to include controlled explosions shortly after the development of gunpowder, and the generation of electricity made other uses possible. The author, a certified solid fuel technician and chimney sweep, as well as a licensed technician for natural gas and propane, has written this book to enable the reader to enjoy safe and dependable wood fires year round by taking the necessary steps. The first recommendation made is against the homeowner installing himself/herself any solid fuel system. It is a job better left to the professionals, considering the substantial product and regulation knowledge and experience required. Specific information related to solid fuel burning technology is included in this book, to be used as a guide. Part 1 of the book deals with the fuel, touching on issues such as energy and the environment, wood combustion and air pollution, buying firewood, wood ashes, cleaning your heating system and others. Part 2 is devoted to the heating system. It introduces topics ranging from the systems advisor to the location and installation of the system, the principles of space heating, high efficiency wood burning, inspections, to name just a few. 22 refs., tabs., figs.

    The factors and demographic features of self-inflicted burns in Eastern and Western cultures differ from each other. In this retrospective study, the authors' aim is to identify the epidemiologic features of self-inflicted burn patients treated at their Tertiary Burn Centre. The Burn Centre provides health care to a large population from Istanbul, which is located at the crossroads between Asia and Europe. The demographic data and information of 32 patients who were admitted to the GATA HEH Burn Center in Istanbul for attempted suicide were retrospectively reviewed over a 7-year period (2001-2008). Twenty-eight of the 32 patients were men, whereas the remaining four patients were women. The average age was 25.9 years. Seventeen patients had a previous history of self-harming and 22 patients were unemployed. History of a psychiatric illness was found in 20 patients. Mean total body burn surface area was 70%. The mortality rate was 43.4%. This study demonstrates that suicide attempts by burning differ from Eastern and Western cultures by factors and demographic features. It has been concluded that the solution to preventing self-inflicted burns calls for the joint efforts of physicians, psychologists, and sociologists. Furthermore, it is necessary to reinstate prevention programs and revise strategies for prevention based on the country and its culture.

    Accurate predictions of equation of state (EOS), ionic and electronic transport properties are of critical importance for high-energy-density plasma science. Transport coefficients inform radiationhydrodynamic codes and impact diagnostic interpretation, which in turn impacts our understanding of the development of instabilities, the overall energy balance of burning plasmas, and the efficacy of selfheating from charged-particle stopping. Important processes include thermal and electrical conduction, electron-ion coupling, inter-diffusion, ion viscosity, and charged particle stopping. However, uncertainties in these coefficients are not well established. Fundamental plasma science codes, also called high-fidelity plasma codes are a relatively recent computational tool that augments both experimental data and theoretical foundations of transport coefficients. This paper addresses the current status of HFPC codes and their future development, and the potential impact they play in improving the predictive capability of the multi-physics hydrodynamic codes used in HED design.

    More than three-quarters of deaths related to major burns are a consequence of infection, which is frequently ventilator associated pneumonia (VAP). A retrospective study was performed, over a five-year period, of ventilated children with major burns. 92 patients were included in the study; their mean age was 3.5 years and their mean total body surface area burn was 30%. 62% of the patients sustained flame burns, and 31% scalds. The mean ICU stay was 10.6 days (range 2-61 days) and the mean ventilation time was 8.4 days (range 2-45 days). There were 59 documented episodes of pneumonia in 52 patients with a rate of 30 infections per 1000 ventilator days. Length of ventilation and the presence of inhalational injury correlate with the incidence of VAP. 17.4% of the patients died (n=16); half of these deaths may be attributed directly to pneumonia. Streptococcus pneumonia, Pseudomonas aeruginosa, Acinetobacter baumanii and Staphylococcus aureus were the most prominent aetiological organisms. Broncho-alveolar lavage was found to be more specific and sensitive at identifying the organism than other methods. This study highlights the importance of implementing strictly enforced strategies for the prevention, detection and management of pneumonia in the presence of major burns. PMID:24468505

    International Nuclear Information System (INIS)

    For over two years the Hospital for Burns in Buenos Aires has been studying the burns caused by radiation, in accordance to an agreement with the Nuclear Regulatory Authority (ARN) of Argentina. The analysis of each case showed the importance of the differential diagnosis from conventional injuries, of this early diagnosis depends the possibility of treatment from the 0 (zero) hour (time at which the accident took place) and achieve the wound healing with the best possible treatment, weather it is medical or surgical in nature. The Hospital's medical staff has developed the necessary skills to recognize this type of burns from an early stage. Most patients arrive to the consultation on their own accord due to the general practitioners inability to correctly diagnose the wounds appeared after radiotherapy has been applied. In this article, we present the general guidelines that the doctors of the Hospital for Burns follow in the presence of radio inducted injuries, objectifying the ethiopathogenic differences of the various burns.

    This study was performed to investigate the burning characteristics of isolated fractions of a biomass species. So, woody shells of hazelnut were chemically treated to obtain the fractions of extractives-free bulk, lignin, and holocellulose. Physical characterization of these fractions were determined by SEM technique, and the burning runs were carried out from ambient to 900 C applying thermal analysis techniques of TGA, DTG, DTA, and DSC. The non-isothermal model of Borchardt-Daniels was used to DSC data to find the kinetic parameters. Burning properties of each fraction were compared to those of the raw material to describe their effects on burning, and to interpret the synergistic interactions between the fractions in the raw material. It was found that each of the fractions has its own characteristic physical and thermal features. Some of the characteristic points on the thermograms of the fractions could be followed definitely on those of the raw material, while some of them seriously shifted to other temperatures or disappeared as a result of the co-existence of the ingredients. Also, it is concluded that the presence of hemicellulosics and celluloses makes the burning of lignin easier in the raw material compared to the isolated lignin. The activation energies can be arranged in the order of holocellulose < extractives-free biomass < raw material < lignin. (author)

    2010-01-01

    Full Text Available Introduction: In-hospital hypernatremia develops usually iatrogenically from inadequate or inappropriate fluid prescription. In severely burned patient an extensive initial fluid resuscitation is necessary for burn shock survival. After recovering of cellular integrity the circulating volume has to be normalized. Hereby extensive water and electrolyte shifts can provoke hypernatremia. Purpose: Is a hypernatremic state associated with increased mortality? Method: Retrospective study for the incidence of hypernatremia and survival in 40 patients with a totally burned surface area (TBSA >10%. Age, sex, TBSA, ABSI-Score and fluid resuscitation within the first 24 hours were analyzed. Patients were separated in two groups without (Group A or with (Group B hypernatremia. Results: Hypernatremia occurred on day 5±1.4. No significant difference for age, sex, TBSA, ABSI-Score and fluid resuscitation within the first 24 hours were calculated. In Group A all patients survived, while 3 of the hypernatremic patient in Group B died during ICU-stay (Odds-ratio = 1.25; 95% CI 0.971–1.61; p=0.046. Conclusion: Burned patients with an in-hospital acquired hypernatremia have an increased mortality risk. In case of a hypernatremic state early intervention is obligatory. There is a need of a fluid removal strategy in severely burned patient to avoid water imbalance.

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

    2012-08-01

    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.

    Burn rehabilitation has been a part of burn care and treatment for many years. Yet, despite of its longevity, the rehabilitation outcome of patients with severe burns is less than optimal and appears to have leveled off. Patient survival from burn injury is at an all-time high. Burn rehabilitation must progress to the point where physical outcomes parallel survival statistics in terms of improved patient well-being. This position article is a treatise on burn rehabilitation and the state of burn rehabilitation patient outcomes. It describes burn rehabilitation interventions in brief and why a need is felt to bring this issue to the forefront. The article discusses areas for change and the challenges facing burn rehabilitation. Finally, the relegation and acceptance of this responsibility are addressed. PMID:18388581

    Background Patient survival following severe burn injury is largely determined by burn size. Modern developments in burn care have tremendously improved survival and outcomes. However, no large analysis on outcomes in pediatric burn patients with current treatment regimen exists. This study was designed to identify the burn size presently associated with significant increases in morbidity and mortality in pediatric burn patients. Methods Single center prospective observational cohort study utilizing the clinical data of severely burned pediatric patients admitted between 1998 and 2009. This study included 952 severely burned pediatric patients with burns over at least 30% of their total body surface area (TBSA). Patients were stratified by burn size in 10% increments, ranging from 30 to 100%, with a secondary assignment made according to the outcome of a receiver operating characteristic (ROC) analysis. Statistical analysis was performed using Student’s t-test, χ2 test, logistic regression and ROC analysis, as appropriate, with significance set at p<0.05. Findings All groups were comparable in age (age in years: 30–39: 6.1±5.1, 40–49: 7.1±5.2, 50–59: 7.6±5.1, 60–69: 7.2±5.1, 70–79: 8.3±5.9, 80–89: 8.4±5.6, 90–100: 9.6±5.4), and gender distribution (male: 30–39: 68%, 40–49: 64%, 50–59: 65%, 60–69: 59%, 70–79: 71%, 80–89: 62%, 90–100: 82%). Mortality (30–39: 3%, 40–49: 3%, 50–59: 7%, 60–69: 16%, 70–79: 22%, 80–89: 35%, 90–100: 55%), multi-organ failure (30–39: 6%, 40–49: 6%, 50–59: 12%, 60–69: 27%, 70–79: 29%, 80–89: 44%, 90–100: 45%), and sepsis (30–39: 2%, 40–49: 5%, 50–59: 6%, 60–69: 15%, 70–79: 13%, 80–89: 22%, 90–100: 26%), increased significantly (p<0.001) among the groups and at a threshold of 62% TBSA.

    Full Text Available Management of burn injury has always been the domain of burn specialists. Since ancient time, local and systemic remedies have been advised for burn wound dressing and burn scar prevention. Management of burn wound inflicted by the different physical and chemical agents require different regimes which are poles apart from the regimes used for any of the other traumatic wounds. In extensive burn, because of increased capillary permeability, there is extensive loss of plasma leading to shock while whole blood loss is the cause of shock in other acute wounds. Even though the burn wounds are sterile in the beginning in comparison to most of other wounds, yet, the death in extensive burns is mainly because of wound infection and septicemia, because of the immunocompromised status of the burn patients. Eschar and blister are specific for burn wounds requiring a specific treatment protocol. Antimicrobial creams and other dressing agents used for traumatic wounds are ineffective in deep burns with eschar. The subeschar plane harbours the micro-organisms and many of these agents are not able to penetrate the eschar. Even after complete epithelisation of burn wound, remodelling phase is prolonged. It may take years for scar maturation in burns. This article emphasizes on how the pathophysiology, healing and management of a burn wound is different from that of other wounds.

    Burning mouth syndrome (BMS) is characterised by the presence of a burning sensation in the oral mucosa in the absence of any clinically apparent mucosal sign. It occurs more commonly in older women and often affects the tongue tip and lateral borders, lips, and hard and soft palates. Besides the burning sensation, patients with BMS may complain of unremitting oral mucosal pain, dysgeusia, and xerostomia. The exact pathophysiology of primary BMS remains unknown. A major challenge for the clinician is the treatment of BMS: identifying possible causative factors is the first step, but BMS is often idiopathic. Drug therapy, in addition to behavioural therapy and psychotherapy, may help to eliminate the symptoms. Considering the growing incidence of BMS in older people, further research is required to determine the true efficacy of current management strategies for patients with this disorder. PMID:26709657

    Ischemic cholangiopathy is a recently described entity occurring mainly after hepatic grafts. Very few cases after intensive care unit (ICU) for extended burn injury were reported. We report the case of a 73-year-old woman consulting in an hepatology unit, for a jaundice appearing during a hospitalisation in an intensive care unit and increasing from her leaving from ICU, where she was treated for an extended burn injury. She had no pre-existing biological features of biliary disease. Biological tests were normal. Magnetic resonance imaging acquisitions of biliary tracts pointed out severe stenosing lesions of diffuse cholangiopathy concerning intrahepatic biliary tract, mainly peri-hilar. Biopsie from the liver confirmed the diagnosis, showing a biliary cirrhosis with bile infarcts. This case is the fourth case of ischemic cholangiopathy after extended burn injury, concerning a patient without a prior history of hepatic or biliary illness and appearing after hospitalisation in intensive care unit.

    Full Text Available Assault chemical burns are uncommon in northern Europe. Besides local toxicity, systemic manifestations are possible after strong acid exposure. A 40-year-old woman was admitted 1 h after a criminal assault with sulfuric acid. The total burned surface area was 35%, third degree. Injury was due to sulfuric acid (measured pH 0.9 obtained from a car battery. Immediate complications were obstructive dyspnea and metabolic acidosis. The admission arterial pH was 6.92, with total bicarbonate 8.6 mEq/l and base deficit 23.4 mEq/l. The correction of metabolic acidosis was achieved after several hours by the administration of bicarbonate and lactate buffers. The patient developed several burns-related complications (sepsis and acute renal failure. Cutaneous projections of strong acids may cause severe metabolic acidosis, particularly when copious irrigation and clothes removal cannot be immediately performed at the scene.

  11. Soil heating and impact of prescribed burning

    Prescribed burning is highly uncommon in the Netherlands, where wildfire awareness is increasing but its risk management does not yet include fuel management strategies. A major exception is on two military bases, that need to burn their fields in winter and spring to prevent wildfires during summer shooting practice. Research on these very frequent burns has so far been limited to effects on biodiversity, yet site managers and policy makers have questions regarding the soil temperatures reached during these burns because of potential impact on soil properties and soil dwelling fauna. In March 2015, I therefore measured soil and litter temperatures under heath and grass vegetation during a prescribed burn on military terrain in the Netherlands. Soil and litter moisture were sampled pre- and post-fire, ash was collected, and fireline intensity was estimated from flame length. While standing vegetation was dry (0.13 g water/g biomass for grass and 0.6 g/g for heather), soil and litter were moist (0.21 cm3/cm3 and 1.6 g/g, respectively). Soil heating was therefore very limited, with maximum soil temperature at the soil-litter interface remaining being as low as 6.5 to 11.5°C, and litter temperatures reaching a maximum of 77.5°C at the top of the litter layer. As a result, any changes in physical properties like soil organic matter content and bulk density were not significant. These results are a first step towards a database of soil heating in relation to fuel load and fire intensity in this temperate country, which is not only valuable to increase understanding of the relationships between fire intensity and severity, but also instrumental in the policy debate regarding the sustainability of prescribed burns.

    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.

    Literature review on addition agents effects on hydrocarbon fuels burning has been conducted. The impact results in flame pattern and burning velocity change, energy efficiency increase, environmentally harmful NOx and CO emission reduction and damping of self-oscillations in flow. An assumption about water molecules dissociation phenomenon existing in a number of practical applications and being neglected in most explanations for physical- chemical processes taking place in case of injection of water/steam into combustion zone has been noted. The hypothesis about necessity of water dissociation account has been proposed. It can be useful for low temperature combustion process control and NOx emission reduction.

    The stage-adjusted therapy of thermal injuries is based on pathophysiologic mechanisms as well as functional and aesthetic requirements. Plastic reconstructive surgical approaches are highly important in the prevention of the frequent grave sequelae of thermal trauma and to achieve optimal functional rehabilitation and favourable outcome. In reconstructive surgery of burns operative goals are subdivided into acute, secondary reconstructive, functional and aesthetic indications. The achievement of early wound closure to preserve functional skin and soft tissue components is an essential part of acute reconstructive procedures. Functional reconstructive and aesthetic procedures supplement the conservative treatment modalities of the secondary phase of burn care with physical therapy, ergotherapy and psychological support.

    BACKGROUND To investigate the effects of platelet-rich plasma on tissue maturation and burn healing in an experimental partial-thickness burn injury model. MATERIAL AND METHODS Thirty Wistar albino rats were divided into 3 groups of 10 rats each. Group 1 (platelet-rich plasma group) was exposed to burn injury and topical platelet-rich plasma was applied. Group 2 (control group) was exposed to burn injury only. Group 3 (blood donor group) was used as blood donors for platelet-rich plasma. The rats were killed on the seventh day after burn injury. Tissue hydroxyproline levels were measured and histopathologic changes were examined. RESULTS Hydroxyproline levels were significantly higher in the platelet-rich plasma group than in the control group (P=.03). Histopathologically, there was significantly less inflammatory cell infiltration (P=.005) and there were no statistically significant differences between groups in fibroblast development, collagen production, vessel proliferations, or epithelization. CONCLUSIONS Platelet-rich plasma seems to partially improve burn healing in this experimental burn injury model. As an initial conclusion, it appears that platelet-rich plasma can be used in humans, although further studies should be performed with this type of treatment.

    When brothers Jamie and Glen Selby, aged 5 and 7, arrived at the Shriners Burns Institute in Denver, Colorado, in July 1983, more than 97% of their skin had been destroyed by a fire they had accidentally started while playing in an abandoned house. The boys were so badly burned that their outlook was grim-a 6-year-old friend who was also in the fire died from his injuries?but Jamie and Glen were lucky. Not only did they survive, but they were also some of the first patients to benefit from a new burn treatment nicknamed test-tube skin. PMID:27414631

    The American Burn Association/Children's Burn Foundation (ABA/CBF) sponsors teams who offer burn education to healthcare providers in Zambia, a sub-Saharan country. The goals of this study are 1) to acquire burn-patient demographics for the Eastern Province, Zambia and 2) to assess the early impact of the ABA/CBF-sponsored burn teams. This is a retrospective chart review of burn patients admitted in one mission hospital in Katete, Zambia, July 2002 to June 2009. July 2002 to December 2006 = data before ABA/CBF burn teams and January 2007 to June 2009 = burn care data during/after burn outreach. There were 510 burn patients hospitalized, male:female ratio 1.2:1. Average age = 15.6 years, with 44% younger than 5 years. Average TBSA burned = 11% and mean fatal TBSA = 25%. Average hospital length of stay = 16.9 days survivors and 11.6 days nonsurvivors. Most common mechanisms of burn injuries: flame (52%) and scald (41%). Ninety-two patients (18%) died and 23 (4.5%) left against medical advice. There were 191 (37.4%) patients who underwent 410 surgical procedures (range 1-13/patient). There were 138 (33.7%) sloughectomies, 118 (28.7%) skin grafts, 39 (9.5%) amputations, and 115 (28.1%) other procedures. Changes noted in the 2007 to 2009 time period: more patients had burn diagrams (48.6 vs 27.6%, P set for a sub-Saharan region in Africa. There has been a statistically significant improvement in documentation of burn size as well as administration of analgesics, validating the efficacy of the ABA/CBF-sponsored burn teams. Continued contact with burn teams may lead to increased use of resuscitation fluids, topical antimicrobials, and more patients undergoing operative intervention, translating into improved burn patient outcomes.

    A year after the most destructive wildfire in Texas (USA) history which occurred in and around Bastrop State Park, we established a 165 m-long study transect, bridging burned and unburned areas, to study post-wildfire soil moisture dynamics. Soil moisture content (θ) was monitored indirectly approximately monthly for half a year using a variety of methods with different measurement scales including: 2D electrical resistivity (ER) imaging and surface and vertical profiles using probes which measure soil dielectric properties. The burned section, where the majority of loblolly pine trees were killed, had higher θ and lower ER whereas the unburned end which is still populated by live pine trees had lower θ and higher ER. This pattern persisted from the ground surface and down to ∼2 m and through the study period even after a rainfall event which made the whole transect generally wetter but with the burned end showing a much stronger wetting response to the storm. The differences in θ cannot be explained by differences in soil texture with the burned end with sand soil and the unburned end with less permeable loamy sand. The differing results may be explained by loss of canopy cover and by reduced transpiration at the burned end where the dead roots may also potentially serve as macropores. Thus, after fires and until new vegetation cover has grown, the burned areas will store and transmit more water which could lead to increased groundwater recharge and promote the recovery or invasion of certain types of vegetation.

    Thermal injuries have been recognized to cause significant neuropsychiatric symptoms and disability in their sufferers since the middle of the 20th century, when Drs. Stanley Cobb and Erich Lindemann of the Massachusetts General Hospital (Boston, MA) studied survivors of the Cocoanut Grove nightclub fire in Boston. Although "burn encephalopathy" or burn-induced delirium is a common occurrence in the acute phase, catatonia in burn patients is not often reported. This report describes a case of malignant catatonia occurring in a 51-year-old male patient acutely suffering from burns acquired in a chemical explosion, effectively treated with reinstitution of a selective serotonin reuptake inhibitor. The literature on burn encephalopathy and catatonia in burns is reviewed. Few examples of burn catatonia exist. Burn encephalopathy is common, and may occur in patients with low TBSA burns such as described in the case above. Descriptions of burn encephalopathy are numerous, but have not included catatonia as a possible etiology. Catatonia in burn patients as an etiology of burn encephalopathy is likely underrecognized. Clinicians should be aware of the possibility of catatonia when a patient's confusional state after a burn does not respond to usual care.

    Burning mouth syndrome (BMS) is mainly found in middle aged or elderly women and is characterized by intense burning or itching sensation of the tongue or other regions of the oral mucosa. It can be accompanied by xerostomia and dysgeusia. The syndrome generally manifests spontaneously, and the discomfort is typically of a continuous nature but increases in intensity during the evening and at night. Although BMS classically has been attributed to a range of factors, in recent years evidence has been obtained relating it peripheral (sensory C and/or trigeminal nerve fibers) or central neuropathic disturbances (involving the nigrostriatal dopaminergic system). The differential diagnosis requires the exclusion of oral mucosal lesions or blood test alterations that can produce burning mouth sensation. Patient management is based on the avoidance of causes of oral irritation and the provision of psychological support. Drug treatment for burning sensation in primary BMS of peripheral origin can consist of topical clonazepam, while central type BMS appears to improve with the use of antidepressants such as duloxetine, antiseizure drugs such as gabapentin, or amisulpride.

    Infection control is very important in burn care units, because burn wound infection is one of the main causes of morbidity and mortality among burn patients. Thus, the appropriate prescription of antibiotics can be helpful, but unreasonable prescription can have detrimental consequences, including greater expenses to patients and community alike. The aim of this study was to determine the effect of antibiotic therapy on the emergence of antibiotic-resistant bacteria. 525 strains of Pseudomonas aeruginosa, Acinetobacter baumannii and Staphylococcus aureus were isolated from 335 hospitalized burn patients. Antibiotic susceptibility tests were performed after identification the strains. The records of patients were audited to find the antibiotic used. The results indicated that P. aeruginosa is the most prevalent Gram-negative bacteria. Further, it showed a relation between abuse of antibiotics and emergence of antibiotic resistance. Control of resistance to antibiotics by appropriate prescription practices not only facilitates prevention of infection caused by multi-drug resistant (MDR) microorganisms, but it can also decrease the cost of treatment.

    At the age of 4, I incurred a major burn injury that left 45% of my body with permanent scars. Normal clothing covers most of the scars. I was able to reclaim a positive body image through a gradual process of verbal and "body" disclosure. As an adult, I joined a burn survivors' self-help group; as a result of talking with other burn survivors, my self expectations increased. Later, I joined a facilitated group in which nudity and personal growth were the norm. In this group, I was the only person who had experienced a major physical trauma. I replaced my strongly held beliefs that others could not accept my unclothed, burn-injured body with the belief that some persons can, and I came to a personal understanding of why others could not. Fun, exercise, and relaxation led to a reclamation of positive feelings about my unclothed body and allowed my femininity and the character of my body image to emerge and become integrated.

    We present a case study of a 10-year-old child with severe burns that were misinterpreted as inflicted burns. Because of multiple injuries since early life, the family was under suspicion of child abuse and therefore under supervision of the Child Care Board for 2 years before the boy was burned. Because the boy incurred the burns without feeling pain, we conducted a thorough medical examination and laboratory testing, evaluated detection and pain thresholds, and used MRI to study brain morphology and brain activation patterns during pain between this patient and 3 healthy age- and gender-matched controls. We found elevated detection and pain thresholds and lower brain activation during pain in the patient compared with the healthy controls and reference values. The patient received the diagnosis of hereditary sensory and autonomic neuropathy type IV on the basis of clinical findings and the laboratory testing, complemented with the altered pain and detection thresholds and MRI findings. Hereditary sensory and autonomic neuropathy IV is a very rare congenital pain insensitivity syndrome characterized by the absence of pain and temperature sensation combined with oral mutilation due to unawareness, fractures, and anhidrosis caused by abnormalities in the peripheral nerves. Health care workers should be aware of the potential presence of this disease to prevent false accusations of child abuse. PMID:24733875

    Full Text Available Biomass burning, the largest global source of elemental carbon (EC and primary organic carbon (OC, is strongly associated with many subjects of great scientific concern, such as secondary organic aerosol and brown carbon which exert important effects on the environment and on climate in particular. This study investigated the relationships between levoglucosan and other biomass burning tracers (i.e., water soluble potassium and mannosan based on both ambient samples collected in Beijing and source samples. Compared with North America and Europe, Beijing was characterized by high ambient levoglucosan concentrations and low winter to summer ratios of levoglucosan, indicating significant impact of biomass burning activities throughout the year in Beijing. Comparison of levoglucosan and water soluble potassium (K+ levels suggested that it was acceptable to use K+ as a biomass burning tracer during summer in Beijing, while the contribution of fireworks to K+ could be significant during winter. Moreover, the levoglucosan to K+ ratio was found to be lower during the typical summer period (0.21 ± 0.16 compared with the typical winter period (0.51 ± 0.15. Levoglucosan correlated strongly with mannosan (R2 = 0.97 throughout the winter and the levoglucosan to mannosan ratio averaged 9.49 ± 1.63, whereas levoglucosan and mannosan exhibited relatively weak correlation (R2 = 0.73 during the typical summer period when the levoglucosan to mannosan ratio averaged 12.65 ± 3.38. Results from positive matrix factorization (PMF model analysis showed that about 50% of the OC and EC in Beijing were associated with biomass burning processes. In addition, a new source identification method was developed based on the comparison of the levoglucosan to K+ ratio and the levoglucosan to mannosan ratio among different types of biomass. Using this method, the major source of biomass burning aerosol in Beijing was suggested to be the combustion of crop residuals, while the

    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.

  15. Narrative review: Electrocution and life-threatening electrical injuries.

    The authors reviewed the mechanisms and pathophysiology of typically encountered electrical injuries by searching English-language publications listed in MEDLINE and reference lists from identified articles. They included relevant retrospective studies, case reports, and review articles published between 1966 and 2005. The authors also searched the Internet for information related to electrocution and life-threatening electrical injuries. They found that familiarity with basic principles of physics elucidates the typical injuries sustained by patients who experience electrical shock. Death due to electrocution occurs frequently. However, patients successfully resuscitated after cardiopulmonary arrest often have a favorable prognosis. Approximately 3000 patients who survive electrical shock are admitted to specialized burn units annually. Patients with serious electrical burns admitted to the intensive care unit are trauma patients and should be treated accordingly. Initial prediction of outcome for patients who have experienced electrical shock is difficult, as the full degree of injury is often not apparent. PMID:17015871

    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.

    Full Text Available Background; Children whose verbal communications are not fully developed are the ones at risk for burn injuries. Causes of burn injuries vary among different age groups and scald injuries are the common cause of burn injuries among children. The majority of burns result from contact with thermal agents such as flame, hot surfaces, or hot liquids.Aim: The aim of this study was to determine etiologic factors of the burn injured children Methods: Data were collected for burn injured children treated in Uludag University Medical Hospital Burn Unit between January 2001 – December 2008. Patients’ demographic variables, etiology of burn injury, TBSA(total body surface area, degree of the burn injury, duration of hospitalization was detected from medical records of the hospitalized patients.Results: The mean age of the children was 2.5±1.5 (median=2. Although 4.6 % of burned patients were under one year of age, most of the children (67.8% were between 1-3 years. All of the patients were burned as a result of accident and house environment was the place where the burn incident occurred. Burn injuries occurredmostly during summer (29.9% and spring (28.7%. Scald injuries (75.3% were mostly seen burn injury types all among other burn injuries.Conclusions: Lack of supervision and observation are usually the most common causes of burn injuries in children. Statistical differences were found among age groups according to their burn etiology (p<0.05. An effect of TBSA on patient survival was statistically significant (p<0.000 and also statistically significant results were seen among age groups according to their TBSA’s (p<0.005.

  1. Bilateral Electrical Cataract: A Case Report

    Full Text Available To present a rare complication, such as bilateral cataracts, in a man who sustained a high-voltage electrical injury. A 35- year-old man was admitted with a complaint of decrease in visual acuity. He had a history of a contact with a power line carrying 30.000 volts of electricity while working at a construction site. Examination at a burn center revealed second-degree facial, neck and left foot burns. One month later, the patient underwent amputation of fourth and fifth toes of his left foot. During the next 6 months, he noted decreasing vision in both eyes. Ocular examination 1 year after the accident revealed that the patient’s visual acuity had deteriorated to 1/10 in both eyes. The cornea on the left eye showed superficial punctate opacities. The lenses in both eyes had anterior subcapsular cortical lens opacities and posterior subcapsular opacities. Uncomplicated bilateral phacoemulsification surgery with intraocular lens implantation was performed and the patient’s visual acuity returned to 10/10 in both eyes. We noted that the fundus remained normal in both eyes. Electrical cataracts are still a serious potential complication that may occur after electrical injury. Awareness of this by burn team members is important for providing optimal treatment to those who have suffered an electrical injury. (Turk J Ophthalmol 2011; 41: 197-9

  3. Ultrasonic pulse-echo determination of burn depth in partial-thickness burns

    International Nuclear Information System (INIS)

    A number of possible techniques for measuring burn depth were considered, and it was concluded that high-frequency ultrasound offers the best possibility for investigation of burn injury. A conventional ultrasonic pulse-echo system was assembled and modified so that small distances in tissue (less than or equal to 1 mm) can be resolved. Typical transducers used during the course of measurements on human and porcine skin are described. Ultimate success of the ultrasonic technique is dependent on the validity of the assumption that the acoustic impedance of necrotic burn tissue is sufficiently different from that of viable tissue to allow for ultrasonic reflections at the interface between burned and viable tissue. In general, this assumption seems to have been valid in animal and human experiments carried out to date

  4. Solar burn reactivation induced by methotrexate.

    2010-04-01

    Solar burn reactivation, a rare and idiosyncratic drug reaction, has been reported with the use of a variety of drugs. This reaction is believed to be the result of exposure to ultraviolet light during the subsiding phase of an acute inflammatory reaction. It affects areas of the body that have been previously sunburned. We describe a 16-year-old girl who was receiving treatment for acute lymphoblastic leukemia and experienced a second-degree solar burn reactivation reaction to methotrexate. The patient had a mild sunburn on her face and shoulders the day she went to the oncology clinic for her interim maintenance chemotherapy with vincristine 1.5 mg/m(2)/dose and methotrexate 100 mg/m(2)/dose. Three days later, she returned to the clinic with a 2-day history of fever (solar burn reactivation reaction. She was admitted to the children's hospital and treated with sodium bicarbonate, acetaminophen with codeine, ondansetron, and silvadene cream. On hospital day 3, the patient's methotrexate level decreased to less than 0.1 mM. The sunburn continued to heal, and after a 14-day hospital stay, complicated by a streptococcal infection, grade 3 mucositis, bacteremia, and mild gastritis and duodenitis, the patient recovered and was discharged. Use of the Naranjo adverse drug reaction probability scale indicated a probable relationship (score of 6) between the patient's solar burn reactivation and methotrexate. Although methotrexate-induced solar burn reactivation is rare, clinicians should be aware of this potential adverse reaction and consider delaying administration of methotrexate by 5-7 days if a patient reports ultraviolet-related erythema in the past 2-4 days or presents with a notable sunburn.

    2000-07-01

    Wood and other forest plant materials were burned in laboratory experiments with the ambition to simulate the natural burning course in a fireplace or a forest fire. Smoke samples were taken and analysed with respect to methoxyphenols, using gas chromatography and mass spectrometry. Different kinds of bio pellets, intended for residential heating were studied in the same way. The aim of a first study was to establish analytical data to facilitate further research. Thirty-six specific methoxyphenols were identified, and gas chromatographic retention and mass spectrometric data were determined for these. In a subsequent study, the methoxyphenol emissions from the burning of wood and other forest plant materials were investigated. Proportions and concentrations of specific methoxyphenols were determined. Methoxyphenols and anhydrosugars, formed from the decomposition of lignin and cellulose respectively, were the most prominent semi-volatile compounds in the biomass smoke. The methoxyphenol compositions reflected the lignin structures of different plant materials. Softwood smoke contained almost only 2-methoxyphenols, while hardwood smoke contained both 2-methoxyphenols and 2,6-dimethoxyphenols. The methoxyphenols in smoke from pellets, made of sawdust, bark and lignin, reflected the source of biomass. Although smoke from incompletely burned wood contains mainly methoxyphenols and anhydrosugars, there is also a smaller amount of well-known hazardous compounds present. The methoxyphenols are antioxidants. They appear mainly condensed on particles and are presumed to be inhaled together with other smoke components. As antioxidants, phenols interrupt free radical chain reactions and possibly counteract the effect of hazardous smoke components. Health hazards of small-scale wood burning should be re-evaluated considering antioxidant effects of the methoxyphenols.

    Wound sepsis is one of the main causes of death in patients with severe burn and trauma. The high incidence of burn wound sepsis in children is attributed to their imperfect immune system function, poor resistance against infection, and the weakened skin barrier function after burn. The key to reduce the mortality of pediatric patients with burn wound sepsis is to enhance the understanding of its etiology, epidemiology, pathogenesis, and diagnostic criteria, in order to improve its early diagnosis and treatment.

  19. Plasma burn-through simulations using the DYON code and predictions for ITER

    CERN Document Server

    Kim, Hyun-Tae; de Vries, P C; Contributors, JET-EFDA

    2014-01-01

    This paper will discuss simulations of the full ionization process (i.e. plasma burn-through), fundamental to creating high temperature plasma. By means of an applied electric field, the gas is partially ionized by the electron avalanche process. In order for the electron temperature to increase, the remaining neutrals need to be fully ionized in the plasma burn-through phase, as radiation is the main contribution to the electron power loss. The radiated power loss can be significantly affected by impurities resulting from interaction with the plasma facing components. The DYON code is a plasma burn-through simulator developed at Joint European Torus (JET) [1] [2]. The dynamic evolution of the plasma temperature and plasma densities including impurity content is calculated in a self-consistent way, using plasma wall interaction models. The recent installation of a beryllium wall at JET enabled validation of the plasma burn-through model in the presence of new, metallic plasma facing components. The simulation...

    Following on from the first publication, (12) concerning the burning of plastics, another 13 chemical pure polymers were burnt in an electric oven to determine the level of solid and gaseous air pollution caused by their stackgases. All 13 polymers are highly combustible but require different burning temperatures (300-900 degrees C) in order to be burnt completely (i.e. without ashrest). With the exception of PMMA and PTFE, all plastics leave a very heavy tar- and soot deposit after burning. At the other end of the scale, burning at low temperature (300 degrees C) gives rise to high concentrations of alipathic aldehyds. The pH of the exhaust-gases, dissolved in water, is neutral to strong acid (PTFE), and will cause a severe corrosion. The nitrogen-containing polymers pollute by forming cyanides, nitrogenoxides and ammonia. PTFE gives off high concentrations of fluorid into the air. PMMA decomposes in its monomer methylmethacrylate and forms large amounts of aliphatic aldehyds. ABS and SBR cause a styrene pollution.

    Full Text Available [english] Background: After a burn injury certain superficial partial-thickness burn wounds spontaneously progress into deep partial-thickness or full-thickness burn wounds. This poorly understood phenomenon is called burn wound progression. The aim of this study was to investigate whether treatment strategies using warm water (preservation of microcirculation on the one side and erythropoietin (EPO (molecule with anti-inflammatory, anti-apoptotic, vasodilatory and neoangiogenic properties can prevent, delay and/or reduce secondary burn wound progression in a rat model.Methods: We used a burn comb model in 63 rats, creating eight rectangular contact burns (2x1 cm each intercalated by unburned zones (2x0.5 cm prone to burn wound progression. In a first experimental set we treated burn wounds with locally applied warm (37°C or cold (17°C water for 20 minutes.In a second experimental set, animals were treated systemically with EPO at two different dosages of 500 and 2,500 IU/kg bodyweight (bw and initiated at 2 different time-points (45 minutes vs. 6 hours after burn injury. Evaluation of microcirculatory perfusion, interspace necrosis and burn depth was performed using respectively laser Doppler flowmetry, planimetry and histology. For statistical analysis the two-way ANOVA-test followed by an adequate post-hoc test (Bonferroni were used. Results: In untreated control animals a conversion from superficial to full-thickness burns was observed within 24 hours. Warm and cold water treatment significantly delayed burn depth progression, nevertheless after 4 days, burn depth was similar in all three groups. Warm water significantly reduced interspace necrosis compared to untreated controls and cold water with a significantly improved perfusion in the warm water group. Surface extension and particularly burn depth progression were significantly decreased by EPO only if administered at a dosage of bw and initiated 45 minutes after burn injury. EPO

  4. Nutrition in the severely burned child.

    Adequate nutrition in the severely burned child often determines the morbidity and mortality and its supervision demands a high priority in the management of the burn injury. A disciplined, detailed programme is required, but this is often neglected. The hypermetabolism experienced in the severe burn may require a calorie intake up to 2 1/2 times normal, and in the growing child, with extra requirements, a negative balance can easily eventuate if careful management is not instituted. A daily metabolic plan provides firstly, the basic calories and protein per kilogram depending on age as for a normal child and, secondly additional requirements depending on the surface area of the burn. With such a programme the weakness of treating all children, whatever their age, on the same formula related only to surface area burn, is overcome. Parenteral nutrition is commenced as soon as the shock phase has been controlled and is continued until enteral intake by gastric tube is sufficient to cover the requirements. Such tube feeding requires the selection of an isotonic liquid diet so as so limit the possibility of diarrhoea. Isocal (Mead Johnson) has been found generally acceptable. Gradually as the patient recovers, oral intake is introduced and the child returns home on a normal nutritional diet, expectantly without weight loss and even with some weight gain, which befits any normal child under treatment for some months. Preburn nutrition, disease and infection, hyperthermia, hypothermia, evaporative water loss, active exercise, psychological well being, social state, early skin cover and limitation of stress are important aspects affecting metabolism and require careful supervision and management. The limitation of metabolism is as important as increasing the caloric intake and this is exemplified at the time of operation, which should be as nonstressful as possible. Every two weeks an adjusted assessment is made of the burned area still to be grafted and the caloric

    2016-04-01

    Burning mouth syndrome (BMS) is a rare but impactful condition affecting mainly post-menopausal women resulting in constant pain and significant difficulty with eating, drinking and daily function. The aetiology of BMS remains an enigma. Recent evidence suggests it likely to be neuropathic in origin, the cause of which remains unknown. There is no cure for this condition and the unfortunate patients remain managed on a variety of neuropathic pain medication, salivary substitutes and other non-medical interventions that help the patient 'get through the day'. Some simple strategies can assist both clinician and patient to manage this debilitating condition. CPD/Clinical Relevance: The dental team will recognize patients presenting with burning mouth syndrome. They are difficult patients to manage and are often referred to secondary care and, ultimately, depend on their general medical practitioners for pain management. PMID:27439272

Attention is focused on explosive burning associated with shell flashes, assuming that nuclear energy is deposited in a mass element, followed by expansion and density decrease. Consideration is given to three cases, the shell flash near the surface of a degenerate star, to nuclear burning concentrated in a small region of a star, and to the heat energy being deposited in intermediate layers. A reaction network of 181 nuclear species was constructed and the thermodynamic evolution was calculated assuming constant pressure and adiabatic conditions. The final products of the reactions of H-1 to Cu-62 were projected to by O-16, Mg-24, Si-28, S-32, Ca-40, Ti-44, Cr-48, and Fe-52.

  7. An idiosyncratic history of burn scars.

    The history of burn scars can best be found in military medical history. The care of wounded soldiers documented in the Illiad reflected the trauma of the weapons of war, arrow, spear, sword, and ax. The introduction of gunpowder in the 14th century, increasingly sophisticated explosives, and in modern times, petroleum-driven vehicles, including airplanes, created a new subset of wounds requiring attention and post-survival scars challenging the quality of survival. This article selects from among a myriad of examples of modern military treatments as they relate to those survivors. Larrey, with Napolean's Grand Army, Sir Harold Gilles during and following World War I, and the Boston area preparation and response to the Cocoanut Grove Fire in 1942 are the principle topics examined. Recent modern interventions, related to the survival of horrific blast and burn injuries, with modern wound care and scar manipulation techniques provide context to the current ability to modify healing and scars.

    Under the DOE Deep Burn program TRISO fuel is being investigated as a fuel form for consuming plutonium and minor actinides, and for greater efficiency in uranium utilization. The result will thus be to drive TRISO particulate fuel to very high burn-ups. In the current effort the various phenomena in the TRISO particle are being modeled using a variety of techniques. The chemical behavior is being treated utilizing thermochemical analysis to identify phase formation/transformation and chemical activities in the particle, including kernel migration. Density functional theory is being used to understand fission product diffusion within the plutonia oxide kernel, the fission product's attack on the SiC coating layer, as well as fission product diffusion through an alternative coating layer, ZrC. Finally, a multiscale approach is being used to understand thermal transport, including the effect of radiation damage induced defects, in a model SiC material.

    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.

  11. Impact of biomass burning on the atmosphere

    International Nuclear Information System (INIS)

    Fire has played an important part in biogeochemical cycling throughout most of the history of our planet. Ice core studies have been very beneficial in paleoclimate studies and constraining the budgets of biogeochemical cycles through the past 160,000 years of the Vostok ice core. Although to date there has been no way of determining cause and effect, concentration of greenhouse gases directly correlates with temperature in ice core analyses. Recent ice core studies on Greenland have shown that significant climate change can be very rapid on the order of a decade. This chapter addresses the coupled evolution of our planet's atmospheric composition and biomass burning. Special attention is paid to the chemical and climatic impacts of biomass burning on the atmosphere throughout the last century, specifically looking at the cycles of carbon, nitrogen, and sulfur. Information from ice core measurements may be useful in understanding the history of fire and its historic affect on the composition of the atmosphere and climate

    , reburning of fly ash appears to be the method that has the highest potential of substantially reducing the amount of unburnt carbon in the ash. Ash from the electric filter should not be circulated, as analyses show that chlorine is concentrated there. The technical conditions and the economic incentives for installing re-burning, vary greatly between plants. The study shows that the economic potential of installing ash reburning systems is high and that reduced fuel costs often is a stronger incentive for an installation than reduced deposit costs. Screening tests show a clear correlation between particle size and content of unburnt carbon in the fly ash. This knowledge can and should be used when re-burning ash. Separating the fly ash and returning the coarser fraction to the furnace makes sure most of the unburnt material is re-burned at the same time as the amount of circulated inorganic material is minimized, thereby also minimizing unnecessary erosion of equipment. The telephone interviews indicated that re-burning ash does not lead to increased emissions of CO or NO{sub x}, which was also confirmed by the field studies. Both plants used for the field studies circulate ash from cyclones that are placed before the final dust separators, in both cases electric filters. If some kind of final dust separation is utilized, the emissions of dust will not be affected by the ash reburn, but if such equipment is missing, emissions of dust will increase as the load on the cyclone separation will increase. Tests with deposit probes have been performed and the results do not show that ash reburning increases the rate of deposit growth or the risk of corrosion.

    The persistent inflammatory response induced by a severe burn increases patient susceptibility to infections and sepsis, potentially leading to multi-organ failure and death. In order to use murine models to develop interventions that modulate the post-burn inflammatory response, the response in mice and the similarities to the human response must first be determined. Here we present the temporal serum cytokine expression profiles in burned in comparison to sham mice and human burn patients. Male C57BL/6 mice were randomized to control (n=47) or subjected to a 35% TBSA scald burn (n=89). Mice were sacrificed 3, 6, 9, 12, 24, 48 hours and 7, 10, and 14 days post-burn; cytokines were measured by multi-plex array. Following the burn injury, IL-6, IL-1β, KC, G-CSF, TNF, IL-17, MIP-1α, RANTES, and GM-CSF were increased, p<0.05. IL-2, IL-3, and IL-5 were decreased, p<0.05. IL-10, IFN-γ, and IL-12p70 were expressed in a biphasic manner, p<0.05. This temporal cytokine expression pattern elucidates the pathogenesis of the inflammatory response in burned mice. Expression of 11 cytokines were similar in mice and children, returning to lowest levels by post-burn day 14, confirming the utility of the burned mouse model for development of therapeutic interventions to attenuate the post-burn inflammatory response.

    Exposure to an electrical arc flash constitutes one of the most serious and fatal electrical injuries. The arc flash creates pressure waves that can damage hearing, eyesight and brain functions and can cause severe burns or death. Between 1998 and 2006, 39 per cent of critical electrical injuries involved burns from an arc flash. Not all electrical injuries are immediately visible, and don't always show up on traditional tests. This article cautioned that symptoms may arise slowly and unpredictably. Currently, Toronto's St. John's Rehab and Sunnybrook Health Sciences Centre are Canada's only specialized rehabilitation and acute care facilities working clinically and publishing research about electrical injuries. Patients from across Canada have been assessed and treated there since the electrical injury program began in 2003. Early intervention is considered to be the best opportunity for anyone who has been in an electrical contact accident. A specialized, comprehensive assessment by a multi-disciplinary team at the health centres results in a plan of care that minimizes future complications such as permanent disability or other long-term effects. 1 ref., 2 figs.

    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

    Objective: To determine the value of the procalcitonin test used for early diagnosis of sepsis and to study the course and treatment of burn sepsis in patients with severe burns. Methods: Eighty patients in the Burn Department of Republican Scientific Centre of Emergency Medical Care, aged 17-75 years with burn injuries covering 30%-85% of the body surface, were enrolled in the study. Procalcitonin is marker of sepsis, procalcitonin > 2 ng/mL, sensitivity -89%, specific feature -94%. Results: The result showed that among septic patients with severe burns, rational use of intensive therapy for burn sepsis and septic shock in combination with parentrial ozonotherapy resulted in decreases of syndrome of poly organ insufficiency and lethal outcomes from 70%accordingly. The result allows the conclusion that the treatment examined leads to a significant increase in survival coefficient. Conclusions: This in turn confirms the efficacy of early necrectomy and auto dermoplasty of deep burn wounds in victims with sepsis.

    Full Text Available Despite the frequency and severity of burns in Low Income Countries, including many in Africa, there is a paucity of research and funding for these populations to aid in prevention, treatment and recovery of burn patients. The objectives of this paper are four-fold. First, by addressing the pathophysiology of burns the reader may strengthen understanding of the clinical progression of burns. Second, through describing proper assessment of burn patients one will learn how to decide if patients can be discharged, admitted or transferred to burn centre. Third, the inclusion of treatments solidifies the steps necessary to manage a patient in a hospital setting. Lastly, the overall goal of the paper, is to raise awareness that more research, publication and funding is required to create a better understanding of burns in Africa and why they continue to be devastating social and economic burdens.

    A prolonged and fulminant inflammatory state, with high levels of pro- and anti-inflammatory mediators, is seen after extensive thermal injury. Blood purification techniques including plasma exchange, continuous venovenous hemofiltration, and adsorbing membranes have the potential to modulate this response, thereby improving outcomes. This article describes the scientific rationale behind blood purification in burns and offers a review of literature regarding its potential application in this patient cohort.

  20. Simulation of an EPRI-Nevada Test Site (NTS) hydrogen burn test at the Central Receiver Test Facility

    International Nuclear Information System (INIS)

    In order to augment results obtained from the hydrogen burn equipment survival tests performed by the Electric Power Research Institute (EPRI) at the Nevada Test Site (NTS), a series of tests was conducted at the Sandia National Laboratories Central Receiver Test Facility (CRTF). The CRTF tests simulated a 13 volume-percent burn from the EPRI-NTS series. During the CRTF tests, the thermal and operational responses of several specimens of nuclear power plant safety-related equipment were monitored when subjected to a solar heat flux simulation of a hydrogen burn. The simulation was conducted with and without steam in the vicinity of the test specimens. Prior to exposure, the specimens were preheated to temperatures corresponding to the precombustion environment in the EPRI-NTS test vessel

    Multi-drug resistant MRSA (methicillin-resistant Staphylococcus aureus) is a global problem for human health, especially skin burn wound patients. Therefore, we estimated the antibacterial and anti-biofilm activity of a chlorhexidine acetate nanoemulsion (CNE) by previously ourselves designed against skin burn wound MRSA infections. Compared with its water solution (CHX), CNE showed a better and faster action against MRSA both in vitro and in vivo. Importantly, CNE was more effective at inhibiting biofilm formation and clearing the biofilm. We also found that the cell walls and membranes of MRSA were severely disrupted after treatment with CNE. Moreover, the relative electrical conductivity and the leakage of alkaline phosphates, K(+), Mg(2+), DNA and protein obviously increased because the cell wall and membrane were damaged. These data show that novel CNE is a promising potential antimicrobial candidate, especially for skin burn wound MRSA infections. PMID:26961464

  2. Best available control measures for prescribed burning

    International Nuclear Information System (INIS)

    Section 190 of the Clean Air Act (CAA) as amended in 1990 requires the US Environmental Protection Agency (EPA) to issue guidance on Best Available Control Measures (BACM) of PM10 (particulate matter with a nominal aerodynamic diameter less than or equal to 10 micrometers) from urban fugitive dust, residential wood combustion, and prescribed silvicultural and agricultural burning (prescribed burning). The purpose of this guidance is to assist states (especially, but not exclusively, those with PM10 nonattainment areas which have been classified as serious) in developing a control measure for these three source categories. This guidance is to be issued no later than May 15, 1992 as required under the CAA. The guidance will be issued in the form of a policy guidance generic to all three BACM and in the form of Technical Information Documents (TIDs) for each of the three source categories. The policy guidance will provide the analytical approach for determining BACM and the TID will provide the technical information. The purpose of this paper is to present some insight from the forthcoming TID on what BACM might entail for prescribed burning in a serious PM10 nonattainment area

  3. A Model For The Burning of Teflon

    Waller, Jess M.; Wilson, D. Bruce; Beeson, Harold D.; Fries, Joseph (Technical Monitor)

    2000-01-01

    Teflon has been identified as suitable material for use in oxygen-enriched atmospheres because of its low specific enthalpy of combustion that is, less than 1500 cal/gram. However, once ignited, Teflon burns in a heterogeneous reaction until total consumption or depletion of oxygen occurs. A model is developed for the burning of Teflon in pure, high-pressure oxygen, 3.4 to 68.9 MPa. The Teflon polymer chain dissociates via monomer units due to pyrolysis. These monomer units diffuse to the surface due to free convection. The model consists of coupled mass and energy balances for the polymer and an energy balance for the free convection of product gases. The model is used to obtain appropriate kinetic parameters for the dissociation and surface reactions. The model is validated against experimental measurements of Teflon discs supported on aluminum rods (2216) at oxygen pressures of 3.4, 6.8, 34.4, and 68.9 MPa. The model simulates the temperature distribution in the product gases above burning Teflon.

    The prevalence of cytomegalovirus in the burn population is high. However, its role in the clinical management of burn patients is still being defined. This report documents a 41-year-old man who developed cytomegalovirus (CMV) colitis after being admitted with a 72% burn. Before the administration of ganciclovir, the authors had difficulty controlling his quantitative wound cultures with serial debridements, topical agents, and systemic antibiotics for known pathogens, which led to graft loss. After the ganciclovir was given, his quantitative wound cultures improved without changing the authors' topical agents or systemic antibiotics and had improved graft take. Whether CMV infection alone contributed to an increased morbidity in this patient or the combination of bacteria/fungal infection with CMV led to a synergistic effect is still not clearly understood. CMV may have contributed to a dysfunction in his cell mediated immunity, which, in turn, lowered the bacterial and fungal load necessary to cause graft loss. Patients who continue to do poorly despite adequate treatment for known pathogens may need to be screened for CMV and treated. PMID:26056763

  8. Opioid-induced hyperalgesia and burn pain.

    Holtman, Joseph R; Jellish, W Scott

    2012-01-01

    The treatment of pain produced during the management of burn injury has been an ongoing problem for physicians caring for these patients. The main therapeutic option for analgesia has been the repeated and prolonged use of opioids. The adverse effects of opioids are well known but the long term use of opioids which produces tolerance with accompanying dose escalation and dependence is most problematic. Another potentially important consequence of opioid exposure that sometimes masks as tolerance is that of opioid induced hyperalgesia. This syndrome is manifest as enhanced pain, sensitivity and loss of analgesic efficacy in patients treated with opioids who actually become sensitized to painful stimuli. This article focuses on the treatment of burn pain and how current analgesic therapies with opioids may cause hyperalgesia and affect the adequacy of treatment for burn pain. This article also provides possible modalities to help therapeutically manage these patients and considers future analgesic strategies which may help to improve pain management in this complicated patient population.

    1992-01-01

    We report 10 seizure-related thermal injuries severe enough to require hospitalization in patients with epilepsy. Eight of the ten incidents were with patients who had had seizures with impaired consciousness two or more times a month. This suggests that seizure frequency is a risk factor and implies the importance of striving for optimal seizure control. Two burns each occurred from an electric iron, a hand-held hair dryer, and stove-top cooking. Minimizing these activities, especially in patients with frequent consciousness-altering seizures, may be useful. Three burns occurred while showering; these resulted in the most severe injuries, with hospital stays of 29, 30, and 41 days. Simple plumbing devices may have prevented these injuries.

    Background Increased burn size leads to increased mortality of burned patients. Whether mortality is due to inflammation, hypermetabolism or other pathophysiologic contributing factors is not entirely determined. The purpose of the present study was to determine in a large prospective clinical trial whether different burn sizes are associated with differences in inflammation, body composition, protein synthesis, or organ function. Methods Pediatric burned patients were divided into four burn size groups: 80% TBSA burn. Demographic and clinical data, hypermetabolism, the inflammatory response, body composition, the muscle protein net balance, serum and urine hormones and proteins, and cardiac function and changes in liver size were determined. Results One hundred and eighty-nine pediatric patients of similar age and gender distribution were included in the study (80% TBSA burn, n = 21). Patients with larger burns had more operations, a greater incidence of infections and sepsis, and higher mortality rates compared with the other groups (P 80% TBSA group, followed by the 60–79% TBSA burn group (P 80% burns lost the most body weight, lean body mass, muscle protein and bone mineral content (P < 0.05). The urine cortisol concentration was highest in the 80–99% and 60–79% TBSA burn groups, associated with significant myocardial depression and increased change in liver size (P < 0.05). The cytokine profile showed distinct differences in expression of IL-8, TNF, IL-6, IL-12p70, monocyte chemoattractant protein-1 and granulocyte–macrophage colony-stimulating factor (P < 0.05). Conclusion Morbidity and mortality in burned patients is burn size dependent, starts at a 60% TBSA burn and is due to an increased hypermetabolic and inflammatory reaction, along with impaired cardiac function.

    Chapter 1 of this thesis describes the various stages of tumor development and a multitude of diagnostic techniques used to detect cancer. Chapter 2 gives an overview of the aspects of hole burning spectroscopy important for its application to the study of cellular systems. Chapter 3 gives general descriptions of cellular organelles, structures, and physical properties that can serve as possible markers for the differentiation of normal and cancerous cells. Also described in Chapter 3 are the principles of cryobiology important for low temperature spectroscopy of cells, characterization of MCF-10F (normal) and MCF-7 (cancer) cells lines which will serve as model systems, and cellular characteristics of aluminum phthalocyanine tetrasulfonate (APT), which was used as the test probe. Chapters 4 and 5 are previously published papers by the author pertaining to the results obtained from the application of hole burning to the study of cellular systems. Chapter 4 presents the first results obtained by spectral hole burning of cellular systems and Chapter 5 gives results for the differentiation of MCF-10F and MCF-7 cells stained with APT by an external applied electric (Stark) field. A general conclusion is presented in Chapter 6. Appendices A and B provide additional characterization of the cell/probe model systems. Appendix A describes the uptake and subcellular distribution of APT in MCF-10F and MCF-7 cells and Appendix B compares the hole burning characteristics of APT in cells when the cells are in suspension and when they are examined while adhering to a glass coverslip. Appendix C presents preliminary results for a novel probe molecule, referred to as a molecular thumbtack, designed by the authors for use in future hole burning applications to cellular systems.

    This appendix on Mass Burn Technologies is the first in a series designed to identify, describe and assess the suitability of several currently or potentially available generic technologies for the management of municipal solid waste (MSW). These appendices, which cover eight core thermoconversion, bioconversion and recycling technologies, reflect public domain information gathered from many sources. Representative sources include: professional journal articles, conference proceedings, selected municipality solid waste management plans and subscription technology data bases. The information presented is intended to serve as background information that will facilitate the preparation of the technoeconomic and life cycle mass, energy and environmental analyses that are being developed for each of the technologies. Mass burn has been and continues to be the predominant technology in Europe for the management of MSW. In the United States, the majority of the existing waste-to-energy projects utilize this technology and nearly 90 percent of all currently planned facilities have selected mass burn systems. Mass burning generally refers to the direct feeding and combustion of municipal solid waste in a furnace without any significant waste preprocessing. The only materials typically removed from the waste stream prior to combustion are large bulky objects and potentially hazardous or undesirable wastes. The technology has evolved over the last 100 or so years from simple incineration to the most highly developed and commercially proven process available for both reducing the volume of MSW and for recovering energy in the forms of steam and electricity. In general, mass burn plants are considered to operate reliably with high availability.

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

    Background Mass burn casualties are always a great challenge to a medical team because a large number of seriously injured patients were sent in within a short time. Usually a high mortality is impending. Experiences gained from successful treatment of the victims may be useful in guiding the care of mass casualties in an armed conflict.Methods Thirty-five burn victims in a single batch, being transferred nonstop by air and highway from a distant province,were admitted 48 hours post-injury. All patients were male with a mean age of (22.4±8.7) years. The burn extent ranged from 4% to 75% ((13.6±12.9)%) total body surface area. Among them, thirty-two patients were complicated by moderate and severe inhalation injury, and tracheostomy had been performed in 15 patients. Decompression incisions of burn eschar on extremities were done in 17 cases before transportation. All the thirty-five patients arrived at the destination smoothly via 4-hour airlift and road transportation. Among them, twenty-five patients were in critical condition.Results These thirty-five patients were evacuated 6 hours from the scene of the injury, and they were transferred to a local hospital for primary emergency care. The patients were in very poor condition when admitted to our hospital because of the severe injury with delayed and inadequate treatment. Examination of these patients at admission showed that one patient was suffering from sepsis and multiple organ dysfunction syndrome. Dysfunction of the heart, lung, liver,kidney, and coagulation were all found in the patients. Forty-eight operations were performed in the 23 patients during one month together with comprehensive treatment, and the function of various organs was ameliorated after appropriate treatment. All the 35 patients survived.Conclusions A well-organized team consisting of several cooperative groups with specified duties is very important. As a whole, the treatment protocol should be individualized, basing on the extent of

    Determining the discharge outcome of burn patients can be challenging and therefore a validated objective measure of functional independence would assist with this process. We developed the Functional Assessment for Burns (FAB) score to measure burn patients' functional independence. FAB scores were taken on discharge from ICU (FAB 1) and on discharge from inpatient burn care (FAB 2) in 56 patients meeting the American Burn Association criteria for major burn. We retrospectively analysed prospectively collected data to measure the progress of patients' physical functional outcomes and to evaluate the predictive validity of the FAB score for discharge outcome. Mean age was 38.6 years and median burn size 35%. Significant improvements were made in the physical functional outcomes between FAB 1 and FAB 2 scores (ppatients were discharged home, 8 of these with social care. 8 patients were transferred to another hospital for further inpatient rehabilitation.

    As indicated in the 2010 United States Religion Census, there are approximately 251,000 Amish people in the United States and Ontario. This census also demonstrated that a new Amish community is founded on average about every three-and-a-half weeks, suggesting that this religious culture is the fastest-growing religion throughout the United States. Because of the rapid growth of the Amish population, it is essential for health care workers to understand their background, cultural, and health care beliefs, especially in the treatment of burns. The purpose of this article is to examine the Amish background, cultural, and health care beliefs, specifically the utilization of burns and wounds ointment and burdock leaves in the treatment of burns.

    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. PMID:23877145

    This article reports the successful experience of integration of burn treatment and rehabilitation for a child suffering from 91% TBSA flame burn injury (with 60% TBSA full-thickness injury, 30% TBSA deep partial-thickness injury, and 1% TBSA superficial partial-thickness injury), severe inhalation injury, severe burn shock, stress ulcer, gastrointestinal bleeding and atelectasis of the right upper lung. The patient was given effective fluid infusion against shock, treatment for gastrointestinal bleeding, and other effective supportive treatment for functions of various organs after being admitted to our burn ward. When vital signs became stable at 30 hours post injury, bedside rehabilitation was begun. On post injury day (PID) 4, escharectomy was performed for both lower limbs, followed by microskin grafting and allogeneic skin covering. On PID 10, invasive infection of multi-drug resistant bacteria was found with accompanied high fever, and at the same time allograft began to disintegrate, with dissolution of large area of eschar, leading to a raw surface reaching 86% TBSA. Following debridement, dressing, application of compound polymyxin B ointment, temporary covering of wounds with porcine acellular dermal matrix, adjustment of antibiotics, patient's condition was finally stabilized. From PID 28 on, split-thickness skin grafting was conducted 7 times, and the raw surface of 75% TBSA involving the upper and lower limbs and trunk was successfully covered. At the same time, our rehabilitation team launched comprehensive rehabilitation measures comprising active exercise, occupational therapy, prevention of scar formation, organ function training and psychological intervention. Finally, the patient was able to walk unaided and fed herself when the wounds were almost entirely healed in 3 months after injury.

    Full Text Available The last decade has seen tremendous advances in atmospheric aerosol particle research that is often performed in the context of climate and global change science. Biomass burning, one of the largest sources of accumulation mode particles globally, has been closely studied for its radiative, geochemical, and dynamic impacts. These studies have taken many forms including laboratory burns, in situ experiments, remote sensing, and modeling. While the differing perspectives of these studies have ultimately improved our qualitative understanding of biomass burning issues, the varied nature of the work make inter-comparisons and resolutions of some specific issues difficult. In short, the literature base has become a milieu of small pieces of the biomass-burning puzzle. This manuscript, the second part of four, examines the properties of biomass-burning particle emissions. Here we review and discuss the literature concerning the measurement of smoke particle size, chemistry, thermodynamic properties, and emission factors. Where appropriate, critiques of measurement techniques are presented. We show that very large differences in measured particle properties have appeared in the literature, in particular with regards to particle carbon budgets. We investigate emissions uncertainties using scale analyses, which shows that while emission factors for grass and brush are relatively well known, very large uncertainties still exist in emission factors of boreal, temperate and some tropical forests. Based on an uncertainty analysis of the community data set of biomass burning measurements, we present simplified models for particle size and emission factors. We close this review paper with a discussion of the community experimental data, point to lapses in the data set, and prioritize future research topics.

    2013-01-01

    Full Text Available In human body, wound healing is a normal biological phenomenon. Burns may be acute or chronic depending upon the source and its time of exposure. Burn wounds may be superficial, partial or full thickness wounds. When skin comes in contact with higher temperature, protein denaturation takes place due to which the plasma membrane integrity is lost. When skin is burned, a number of inflammatory mediators and releasing agents such as histamine, nitric oxide, oxygen free radicals, eicosanoid products, tumor necrosis factors, and interleukins etc., are released at the site. For wound healing mechanism, the keratinocytes has to move from uninjured site to the burned area. For deeper burns this process takes a long time. By some unknown mechanisms, burn wounds may convert from one form to another form. So burn wound depth must be accurately measured before starting the treatment to prevent the complications. Burns can be induced in experimental animals by using different models. Many treatments such as herbal drugs, topical agents, gene therapy, volume therapy, and rehabilitation can be employed. This review article mainly deals with the theoretical and practical aspects of burn wound healing. Some burn wound healing plants with their chemical constituents, plant part used, uses and animal models are described here.

    Full Text Available Burn trauma is an important public health concern, with increased risk for burns in children. A cross-sectional study was performed to describe the epidemiological characteristics and risk factors for burns in hospitalized Bedouin children in Soroka University Medical Center during the years 2001–2002. In a population of 558 hospitalized burn-injured patients, 282 Bedouin children were identified. Two hundred and sixty five patients (94.0% had burns involving less than 20% of the body surface area. Cause of the burns was scald in 190 patients (67.4%, fire in 80 patients (28.4%, chemical in 8 patients (2.8%, and explosion in 2 patients (0.7%. Two female patients (0.7% aged 11 and 17 years died of their burns that were caused by fire. The mean length of hospitalization was 9.8 days. Pediatric burn injury has become a significant public health problem in the Bedouin population of the Negev. To reduce the burden of burn injury, it is necessary to increase current efforts in prevention of burns.

    Liquefied petroleum gas (LPG) is a fuel that is widely used for domestic, agricultural, and industrial purposes. LPG is also commonly used in restaurants, industries, and cars; however, the home continues to be the main site for accidents. In Turkey, the increased usage of LPG as a cooking or heating fuel has resulted in many burn injuries from LPG mishaps. Between January 2000 and June 2011, 56 LPG-burned patients were compared with 112 flame-burned patients. There were no significant differences with respect to the mean age, sex, hospitalization time, and mortality in both groups. In the LPG-caused burn cases, 41 burns (73.2%) occurred at home, seven (12.5) were work-related mishaps, and eight (14.3) were associated with car accidents. The majority of the LPG burns (82%, 46 patients) resulted from a gas leak, and 18% of them were related to the failure to close LPG tubes in the patients' kitchens (10 patients). Burns to the face and neck (82 vs 67%, P = .039) and upper (62 vs 23%, P = .000) and lower (70 vs 45%, P = .002) extremities were significantly higher in LPG-caused burn cases than flame-burned cases. General awareness regarding the risk of LPG and first aid for burns appears to be lacking. The LPG delivery system should be standardized throughout countries that widely use LPG.

    A severe burn is associated with release of inflammatory mediators which ultimately cause local and distant pathophysiological effects. Mediators including Reactive Oxygen Species (ROS) and Reactive Nitrogen Species (RNS) are increased in affected tissue, which are implicated in pathophysiological events observed in burn patients. The purpose of this article is to understand the role of oxidative stress in burns, in order to develop therapeutic strategies. All peer-reviewed, original and review articles published in the English language literature relevant to the topic of oxidative stress in burns in animals and human subjects were selected for this review and the possible roles of ROS and RNS in the pathophysiology of burns are discussed. Both increased xanthine oxidase and neutrophil activation appear to be the oxidant sources in burns. Free radicals have been found to have beneficial effects on antimicrobial action and wound healing. However following a burn, there is an enormous production of ROS which is harmful and implicated in inflammation, systemic inflammatory response syndrome, immunosuppression, infection and sepsis, tissue damage and multiple organ failure. Thus clinical response to burn is dependent on the balance between production of free radicals and its detoxification. Supplementation of antioxidants in human and animal models has proven benefit in decreasing distant organ failure suggesting a cause and effect relationship. We conclude that oxidative damage is one of the mechanisms responsible for the local and distant pathophysiological events observed after burn, and therefore anti-oxidant therapy might be beneficial in minimizing injury in burned patients.

    Pain is a major problem after burns and researchers continue to report that pain from burns remains undertreated. The inadequate pain control results in adverse sequalae physically and psychologically in the burn victims. A better understanding of a burn patient's experience is important in identifying the factors responsible for undertreated pain and establishing effective pain management guidelines or recommendation in the practice of pain relief for burn injuries. This study sought to explore and describe the experience that patients have about pain related to burn-injury during hospitalization. Semi-structured interviews were conducted on eight patients with moderate to severe pain from burn injuries recruited from a Burn Centre in Northwest China. Data was collected by in-depth interviews and qualitative description after full transcription of each interview. Analysis involved the identification of themes and the development of a taxonomy of patients' experience of burn pain and its management. Three themes were indentified: (1) patients' experience of pain control, (2) patients' perception on burn pain management, and (3) patients' expectation of burn pain management. Findings from this study suggested that patients experience uncontrolled pain both physically and psychologically which may serve as an alert for awareness of health professionals to recognize and establish a multidisciplinary pain management team for burn victims, including surgeons, critical care specialists, anesthesiologists, nurses, psychologists, and social workers to accomplish safe and effective strategies for pain control to reach an optimal level of pain management in burn patients. It also provides insights and suggestions for future research directions to address this significant clinical problem.

    Objective: To verify the moisture maintaining effect of moist exposed burn ointment (MEBO) in treating burn wound. Methods: Rabbit model with II degree burn wound was used in this study. Observations were conducted at 0 (before burn), 0.5, 6, 24, 48, 72, and 168 hours postburn. The data of wound water evaporation, wound appearance and pathological changes of the wounds were compared with that of the burn wounds treated with Vaseline or conventional dry exposed therapy. Results: It was found that wounds treated with MEBO had water evaporation close to that of normal skin and was significantly less than that of the wounds treated with dry exposed therapy (P<0.01) MEBO did not obstruct water evaporation from wound as Vaseline did(P<0.01).Wounds treated with MEBO had good permeability and adequate drainage. Conclusion: MEBO provided the wounds with a physiological moist environment

    We present an analysis of ozone (O3) photochemistry observed by aircraft measurements of boreal biomass burning plumes over eastern Canada in the summer of 2011. Measurements of O3 and a number of key chemical species associated with O3 photochemistry, including non-methane hydrocarbons (NMHCs), nitrogen oxides (NOx) and total nitrogen containing species (NOy), were made from the UK FAAM BAe-146 research aircraft as part of the "quantifying the impact of BOReal forest fires on Tropospheric oxidants over the Atlantic using Aircraft and Satellites" (BORTAS) experiment between 12 July and 3 August 2011. The location and timing of the aircraft measurements put BORTAS into a unique position to sample biomass burning plumes from the same source region in Northwestern Ontario with a range of ages. We found that O3 mixing ratios measured in biomass burning plumes were indistinguishable from non-plume measurements, but evaluating them in relationship to measurements of carbon monoxide (CO), total alkyl nitrates (ΣAN) and the surrogate species NOz (= NOy-NOx) revealed that the potential for O3 production increased with plume age. We used NMHC ratios to estimate photochemical ages of the observed biomass burning plumes between 0 and 10 days. The BORTAS measurements provided a wide dynamic range of O3 production in the sampled biomass burning plumes with ΔO3/ΔCO enhancement ratios increasing from 0.020 ± 0.008 ppbv ppbv-1 in plumes with photochemical ages less than 2 days to 0.55 ± 0.29 ppbv ppbv-1 in plumes with photochemical ages greater than 5 days. We found that the main contributing factor to the variability in the ΔO3/ΔCO enhancement ratio was ΔCO in plumes with photochemical ages less than 4 days, and that was a transition to ΔO3 becoming the main contributing factor in plumes with ages greater than 4 days. In comparing O3 mixing ratios with components of the NOy budget, we observed that plumes with ages between 2 and 4 days were characterised by high aerosol

  14. In situ oil burning in the marshland environment : soil temperatures resulting from crude oil and diesel fuel burns

    International Nuclear Information System (INIS)

    The unique challenge associated with oil spill cleanups in sensitive marsh environments was discussed. Mechanical recovery of crude or refined hydrocarbons in wetlands may cause more damage to the marsh than the oil itself. This study evaluated whether in situ burning of oiled marshlands would provide a less damaging alternative than mechanical recovery. This was done through a series of 6 crude oil and 5 diesel fuel burns conducted in a test tank to examine the impact of intentional burning of oil spilled in a wetlands environment. There are several factors which may influence how well such an environment would recover from an in situ oil burn, such as plant species, fuel type and load, water level, soil type, and burn duration. This paper focused on soil, air and water temperatures, as well as total heat fluxes that resulted when 3 plant species were exposed to full-scale in situ burns that were created by burning diesel fuel and crude oil. The soil temperatures were monitored during the test burn at three different soil/water elevations for 700 second burn exposures. A total of 184 plant sods were harvested from marshlands in southern Louisiana and were subjected to the burning fuel. They were instrumental in characterizing the thermal and chemical stress that occur during an in-situ burn. The plants were inserted into the test tanks at various water and soil depths. The results indicated that diesel fuel and crude oil burns produced similar soil temperature profiles at each of three plant sod elevations. Although in-situ burning did not appear to remediate oil that had penetrated into the soil, it did effectively remove floating oil from the water surface, thereby preventing it from potentially contaminating adjacent habitats and penetrating the soil when the water recedes. The regrowth and recovery of the plants will be described in a separate report. 25 refs., 7 tabs., 15 figs

    Nowadays, despite improvements in safety rules and inspections in the metal industry, foundry workers are not free from burn accidents. Injuries caused by molten metals include burns secondary to molten iron, aluminium, zinc, copper, brass, bronze, manganese, lead and steel. Molten aluminium is one of the most common causative agents of burns (60%); however, only a few publications exist concerning injuries from molten aluminium. The main mechanisms of lesion from molten aluminium include direct contact of the molten metal with the skin or through safety apparel, or when the metal splash burns through the pants and rolls downward along the leg. Herein, we report three cases of deep dermal burns after 'soaking' the foot in liquid aluminium and its evolutive features. This paper aims to show our experience in the management of burns due to molten aluminium. We describe the current management principles and the key features of injury prevention.

    Electrolyte abnormalities are common in the severely burned patient. There is little information with regard to the frequency and magnitude of hypomagnesemia, as well as on risk factors for this condition. We performed an observational, retrospective analysis of 35 burned patients treated at the Plastic and Reconstructive Surgery Service at the Hospital Central Sur PEMEX, Mexico City. We determined serum magnesium behavior and divided patients into two groups: the first included 11 patients with burns and hypomagnesemia, and the second, 24 patients with burns but without hypomagnesemia. Risk factor identification was performed. We found patient at risk was the one with more than 40% of 2nd or 3rd degree total burned body area, in day 4 or 10 after the burn, and with hypokalemia, hypocalcemia, or both, and without intravenous (i.v.) supplementation of magnesium. The best way to prevent or avoid major complications is to identify the high-risk patient, or to diagnose earlier. PMID:15633562

    Burn trauma is in need for prognostic indicators or admission scores. This aims for realistic documentation of the burn injury, expectation of the prognosis, and to facilitate a patient stratification to evaluate therapeutic strategies. A computer search through different medical websites was performed looking for articles correlating prognosis with different burn indices. These were carefully summarized and analyzed for this review. Variable studies were found related to that issue; the reliable indicators found had been classified as general or specific. All of them had certain clinical importance, but limitations are a common feature. All the listed indices are useful to serve in the only special clinical situations. We couldn't claim that they are actual prognostic indicator in burn victims. We believe that we still lack the proper prognostic indicator in burn patients. Researchers are invited for more effort to organize a more reliable prognostic indicator and scoring system for burn patients.

    Objective To improve clinical outcome and to determine new treatment options, we studied the pathophysiologic response postburn in a large prospective, single center, clinical trial. Summary Background Data A severe burn injury leads to marked hypermetabolism and catabolism, which are associated with morbidity and mortality. The underlying pathophysiology and the correlations between humoral changes and organ function have not been well delineated. Methods Two hundred forty-two severely burned pediatric patients [>30% total body surface area (TBSA)], who received no anabolic drugs, were enrolled in this study. Demographics, clinical data, serum hormones, serum cytokine expression profile, organ function, hypermetabolism, muscle protein synthesis, incidence of wound infection sepsis, and body composition were obtained throughout acute hospital course. Results Average age was 8 ± 0.2 years, and average burn size was 56 ± 1% TBSA with 43 ± 1% third-degree TBSA. All patients were markedly hypermetabolic throughout acute hospital stay and had significant muscle protein loss as demonstrated by a negative muscle protein net balance (−0.05% ± 0.007 nmol/100 mL leg/min) and loss of lean body mass (LBM) (−4.1% ± 1.9%); P < 0.05. Patients lost 3% ± 1% of their bone mineral content (BMC) and 2 ± 1% of their bone mineral density (BMD). Serum proteome analysis demonstrated profound alterations immediately postburn, which remained abnormal throughout acute hospital stay; P < 0.05. Cardiac function was compromised immediately after burn and remained abnormal up to discharge; P < 0.05. Insulin resistance appeared during the first week postburn and persisted until discharge. Patients were hyperinflammatory with marked changes in IL-8, MCP-1, and IL-6, which were associated with 2.5 ± 0.2 infections and 17% sepsis. Conclusions In this large prospective clinical trial, we delineated the complexity of the postburn pathophysiologic response and conclude that the postburn

In addition, the effects of loss of diversity and need to preserve Indian cultures and societies are briefly discussed

  4. Spectral hole burning studies of photosystem II

    Low temperature absorption and hole burning spectroscopies were applied to the D1-D2-cyt b{sub 559} 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 Q{sub y}-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 {approximately} 1 cm{sup -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.

    We present theory and experiments on the dynamics of reaction fronts in a two-dimensional flow composed of a chain of alternating vortices. Inspired by the organization of passive transport by invariant manifolds, we introduce burning invariant manifolds (BIMs), which act as one-sided barriers to front propagation. The BIMs emerge from the theory when the advection-reaction- diffusion system is recast as an ODE for reaction front elements. Experimentally, we demonstrate how these BIMs can be measured and compare their behavior with simulation. Finally, a topological BIM formalism yields a maximum front propagation speed.

    Climate change policies have stimulated a shift towards renewable energy sources such as biomass. The economic crisis of 2008 has also increased the practice of household biomass burning as it is often cheaper than using oil, gas or electricity for heating. As a result, household biomass combustion is becoming an important source of air pollutants in the European Union.This position paper discusses the contribution of biomass combustion to pollution levels in Europe, and the emerging evidence on the adverse health effects of biomass combustion products.Epidemiological studies in the developed world have documented associations between indoor and outdoor exposure to biomass combustion products and a range of adverse health effects. A conservative estimate of the current contribution of biomass smoke to premature mortality in Europe amounts to at least 40 000 deaths per year.We conclude that emissions from current biomass combustion products negatively affect respiratory and, possibly, cardiovascular health in Europe. Biomass combustion emissions, in contrast to emissions from most other sources of air pollution, are increasing. More needs to be done to further document the health effects of biomass combustion in Europe, and to reduce emissions of harmful biomass combustion products to protect public health. PMID:26405285

    Aerodigestive tract burns represent a rare but potentially devastating injury pattern throughout the world. Although the majority of these injuries do not require intervention, these burns have the potential for poor outcomes. Traditionally this disease has been caused by superheated gases found in explosions or fire-related injury. However, as technology advances, it brings novel methods for injury that require physician awareness of potential hazards. We describe a case of laryngeal and esophageal thermal burn caused by a microwave heated food bolus.

    In order to investigate the pyrolytic characteristics of the burning residue of fire-retardant wood,a multifunctional fire-resistance test oven aimed at simulating the course of a fire was used to burn fire-retardant wood and untreated wood.Samples at different distances from the combustion surface were obtained and a thennogravimetric analysis (TG) was applied to test the pyrolytic process of the burning residue in an atmosphere of nitrogen.The results showed that:1) there was little difference between fireretardant wood and its residue in the initial temperature of thermal degradation.The initial temperature of thermal degradation of the combustion layer in untreated wood was higher than that in the no burning wood sample;2) the temperature of the flame retardant in fire-retardant wood was 200℃ in the differential thermogravimetry (DTG).The peak belonging to the flame retardant tended to dissipate during the time of burning;3) for the burning residue of fire-retardant wood,the peak belonging to hemicellulose near 230℃ in the DTG disappeared and there was a gentle shoulder from 210 to 240℃;4) the temperature of the main peaks of the fireretardant wood and its burning residue in DTG was 100℃ lower than that of the untreated wood and its burning residue.The rate of weight loss also decreased sharply;5) the residual weight of fire-retardant wood at 600~C clearly increased compared with that of untreated wood.Residual weight of the burning residue increased markedly as the heating temperature increased when burning;6) there was a considerable difference with respect to the thermal degradation temperature of the no burning sample and the burning residue between fire-retardant wood and untreated wood.

  4. Functional characterization of cultured keratinocytes after acute cutaneous burn injury.

    Directory of Open Access Journals (Sweden)

    Gerd G Gauglitz

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

  7. Comparative study of pulsed and steady-state tokamak reactor burn cycles

    International Nuclear Information System (INIS)

    Four distinct operating modes have been proposed for tokamaks. Our study focuses on capital costs and lifetime limitations of reactor subsystems in an attempt to quantify sensitivity to pulsed operation. Major problem areas considered include: thermal fatigue on first wall, limiter/divertor; thermal energy storage; fatigue in pulsed poloidal field coils; out-of-plant fatigue and eddy current heating in toroidal field coils; electric power supply costs; and noninductive driver costs. We assume a high availability and low cost of energy will be mandatory for a commercial fusion reactor, and we characterize improvements in physics and engineering which will help achieve these goals for different burn cycles

    Acute experiments were conducted on rats; repeated extensive burn of a convalescent who formerly sustained the burn disease was better tolerated, led tono fatal outcome and was accompanied by moderate microcirculatory disturbances. The smae burn was accompanied in intact rats by a severe shock followed by death, intravascular aggregation of erythrocytes and significant microcirculatory disturbances leading to disturbance of tissue nutrition. It is supposed that the results obtained could serve as an indirect proof that toxemia played an important role in the genesis of intravascular aggregation of erythrocytes in burn shock.

    The main result of esophagus burn is the formation of scars, that caused by excessive synthesis of collagen and changes the balance of metalloproteinases and their tissue inhibitors. It was studied the activity of proteolytic enzymes, participation of MMP (metalloproteinase) and their tissue inhibitors (TIMP) in alkali burns of the esophagus 1st and 2nd degrees. We have shown a significant increase of TIMP level in homogenate after alkali burns of the esophagus (an average of 31-56% depend on of burn degree). We observed a reduced activity of serine proteinase after 1st degree burns on 15th, 21st day 35 and 18% respectively, after burns 2nd degree on 15th, 21st day 54 and 50%. The decrease of activity MMP after 1st degree burns on 15th and 21st day 30, 19%, respectively, in conditions of chemical burns 2nd degree on 15th and 21st day 30, 37%. These data may indicate the development of scarring after burn simulation of 2nd degree. Further investigation of the MMP and TIMP in the process of wound healing can be useful in creating effective approaches to prevent formation of post scarring of the esophagus.

    Wildland fire is the dominant large-scale disturbance mechanism in the Alaskan boreal forest, and it strongly influences forest structure and function. In this research, patterns of burn severity in the Alaskan boreal forest are characterised using 24 fires. First, the relationship between burn severity and area burned is quantified using a linear regression. Second, the spatial correlation of burn severity as a function of topography is modelled using a variogram analysis. Finally, the relationship between vegetation type and spatial patterns of burn severity is quantified using linear models where variograms account for spatial correlation. These results show that: 1) average burn severity increases with the natural logarithm of the area of the wildfire, 2) burn severity is more variable in topographically complex landscapes than in flat landscapes, and 3) there is a significant relationship between burn severity and vegetation type in flat landscapes but not in topographically complex landscapes. These results strengthen the argument that differential flammability of vegetation exists in some boreal landscapes of Alaska. Additionally, these results suggest that through feedbacks between vegetation and burn severity, the distribution of forest vegetation through time is likely more stable in flat terrain than it is in areas with more complex topography. ??

    The first summer camps for children with burn injuries started over 25 years ago, and as of 2008, there were 60 camps worldwide. This review examines the literature on summer pediatric burn camps. The authors describe common characteristics of burn camp structure, activities, and staffing and then examine the scientific evidence regarding the effect of burn camp programs on campers and camp staff volunteers. A search of Pubmed and Psychinfo databases from 1970 to 2008 for articles related to pediatric burn summer camps identified 17 articles, of which 13 fit the inclusion criteria. Existing literature consists primarily of qualitative studies, suggesting that burn camp can decrease camper isolation, improve self-esteem, and promote coping and social skills. Studies examining volunteer staff at burn camp have consistently found that there are both personal and professional benefits. Quantitative studies of self-esteem have yielded equivocal results. No studies have examined safety or the effect of burn camp on medical or rehabilitation outcomes. For the past 25 years, pediatric summer camps for children with burn injuries have played an important rehabilitation role and provided a strong community that benefits both campers and staff. Future research using more rigorous research methods and examining a broader range of outcomes (eg, safety and medical/rehabilitation outcomes) is recommended. PMID:20644489

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

    Full Text Available Every year, about 2.5 million people are affected from burns in the world. In our country there is no reliable database related to this subject. There are ongoing studies about the epidemiology of burns in Turkey. After burn injury had represent many various complications, such as myocardial infarction, cardiac deficiency, acute hypertension, endocarditis, thromboembolism, pulmonary edema, pneumonia, respiratuar failure, renal failure, gastric ulcus, ileus, sepsis, coagulopathy and anemia. Such complications can preventable or treatable. In this respect, preventive management in the first step burn treatment had very importantly in burn cases. Skin is a barrier which protects evaporative heat loss. In cases of acute burn, hypothermia occurs related to skin loss. For these cases, care must be taken to keep the patient warm. In addition fluid resuscitation is very important in these cases. Furthermore, the damaged tissues are highly susceptible to infection in burned patients. Burn care and rehabilitation includes challenging and complex procedures. Briefly, treatments of burn cases require a multidisciplinary and meticulous approach.

  20. Gram-Negative Bacterial Infection in Thigh Abscess Can Migrate to Distant Burn Depending on Burn Depth

    Full Text Available Sepsis remains the major cause of death in patients with major burn injuries. In the present investigation we evaluated the interaction between burn injuries of varying severity and preexisting distant infection. We used Gram-negative bacteria (Pseudomonas aeruginosa and Proteus mirabilis that were genetically engineered to be bioluminescent, which allowed for noninvasive, sequential optical imaging of the extent and severity of the infection. The bioluminescent bacteria migrated from subcutaneous abscesses in the leg to distant burn wounds on the back depending on the severity of the burn injury, and this migration led to increased mortality of the mice. Treatment with ciprofloxacin, injected either in the leg with the bacterial infection or into the burn eschar, prevented this colonization of the wound and decreased mortality. The present data suggest that burn wounds can readily become colonized by infections distant from the wound itself.

    Fire has played an important part in biogeochemical cycling throughout most of the history of our planet. Ice core studies have been very beneficial in paleoclimate studies and constraining the budgets of biogeochemical cycles through the past 160,000 years of the Vostok ice core. Although to date there has been no way of determining cause and effect, concentration of greenhouse gases directly correlates with temperature in ice core analyses. Recent ice core studies on Greenland have shown that significant climate change can be very rapid on the order of a decade. This chapter addresses the coupled evolution of our planet`s atmospheric composition and biomass burning. Special attention is paid to the chemical and climatic impacts of biomass burning on the atmosphere throughout the last century, specifically looking at the cycles of carbon, nitrogen, and sulfur. Information from ice core measurements may be useful in understanding the history of fire and its historic affect on the composition of the atmosphere and climate.

    Burns of the penis can be physically and psychologically devastating. This is particularly true in young pediatric patients who have to content with growth as well as with the trials of adolescence and the development of self-image. Little has been written on the grafting management of these injuries. This report reviews a management technique used with great success. Ten patients who sustained full-thickness penis burns were reviewed. The grafting technique consisted of excision and grafting with sheet grafts in a one- or two-stage setting. After grafting, the penis was placed in traction with a weighted Foley catheter. Grafts were left open or stented. No complications occurred from the traction apparatus, and graft take was uniformly excellent. Short-term results have been excellent, and no urethral problems have developed over a median 3-year follow-up. This technique appears to provide excellent means of supporting the penis to accomplish superb graft take in this hard-to-manage area.

The aim of this study was to investigate the existence of post-traumatic stress disorder (PTSD and predictors of PTSD Checklist score initially and 3 months after injury in burns victims admitted to the Sina Burn Center in north-west Iran.Methods: This prospective study examined adult patients aged 16–65 years with unintentional burns. The PTSD Checklist was used to screen for PTSD.Results: Flame burns constituted 49.4% of all burns. Mean PTSD score was 23.8 ± 14.7 early in the hospitalization period and increased to 24.2 ± 14.3, 3 months after the burn injury. Twenty percent of victims 2 weeks into treatment had a positive PTSD screening test, and this figure increased to 31.5% after 3 months. The likelihood of developing a positive PTSD screening test increased significantly after 3 months (P < 0.01. Using multivariate regression analysis, factors independently predicting PTSD score were found to be age, gender, and percentage of total body surface area burned.Conclusion: PTSD was a problem in the population studied and should be managed appropriately after hospital admission due to burn injury. Male gender, younger age, and higher total body surface area burned may predict a higher PTSD score after burn injury. Keywords: post-traumatic stress disorder, burn injury, predictors, Iran

    The extensive skin defects induced by severe burns are dangerous and can be fatal. Currently, the most common therapy is tangential excision to remove the necrotic or denatured areas of skin, followed by skin grafting. Xenogeneic dermal substitutes, such as porcine acellular dermal matrix (ADM), are typically used to cover the burn wounds, and may accelerate wound healing. It is assumed that burned skin that still maintains partial biological activity may be recycled to construct an autologou...

    The aim of this study was describe national trends in prevalence, demographics, hospital length of stay (LOS), hospital charges, and mortality for burn patients with and without inhalational injury and to compare to the National Burn Repository. Burns and inhalation injury cause considerable mortality and morbidity in the United States. There remains insufficient reporting of the demographics and outcomes surrounding such injuries. The National Inpatient Sample database, the nation's largest all-payer inpatient care data repository, was utilized to select 506,628 admissions for burns from 1988 to 2008 based on ICD-9-CM recording. The data were stratified based on the extent of injury (%TBSA) and presence or absence of inhalational injury. Inhalation injury was observed in only 2.2% of burns with burns with 80 to 99% TBSA. Burn patients with inhalation injury were more likely to expire in-hospital compared to those without (odds ratio, 3.6; 95% confidence interval, 2.7-5.0; P Patients treated at rural facilities and patients with hyperglycemia had lower mortality rates. Each increase in percent of TBSA of burns increased LOS by 2.5%. Patients with burns covering 50 to 59% of TBSA had the longest hospital stay at a median of 24 days (range, 17-55). The median in-hospital charge for a burn patient with inhalation injury was US$32,070, compared to US$17,600 for those without. Overall, patients who expired from burn injury accrued higher in-hospital charges (median, US$50,690 vs US$17,510). Geographically, California and New Jersey were the states with the highest charges, whereas Vermont and Maryland were states with the lowest charges. The study analysis provides a broad sampling of nationwide demographics, LOS, and in-hospital charges for patients with burns and inhalation injury.

Low grade heat is heat, which isavailable at a low temperature, e.g. from waste heat from marine diesel engines...... and industrial processes orfrom geothermal and solar heat sources. Utilization of such heat sources makes it possible to produce electricity with no additional burning of fossil fuel, and does therefore represent an environmentally friendly alternative to fossil fuel based electricity production.

    2016-02-01

    The length of hospital stay (LOS) is a standard parameter used to reflect quality and evaluate outcomes in acute burn care. This study aims to assess whether the target of 1 day of stay per 1% total body surface area (TBSA) burned was achieved in acute chemical burns management and factors affecting the LOS. A retrospective analysis of the records of patients who suffered from chemical burn injuries admitted to a university burn center over a continuous 14-year period was performed.A total of 118 patients were admitted over the period for chemical burns. Only 14% of cases achieved the target stated. Factors associated with lengthening of the hospital stay included TBSA, ocular involvement, the cause of injury, and the need for surgery during the same admission.The LOS in chemical burns frequently exceeds 1 day of stay per 1% TBSA burned. Many factors can contribute to a patient's LOS and are worth exploring in order to see if the impact of these factors could be minimized. Early surgical intervention should help to reduce the LOS if reliable methods of burn wound depth assessment are available.

    Burn wound sepsis is currently the main cause of morbidity and mortality after burn trauma. Infections by notorious pathogens such as Pseudomonas aeruginosa, Staphylococcus aureus, and Acinetobacter baumannii impair patient recovery and can even lead to fatality. In this study, we investigated the effect of burn wound exudates (BWEs) on the virulence of those pathogens. BWEs were collected within 7 days after burn trauma from 5 burn patients. We first monitored their effect on pathogen growth. In contrast to A. baumannii and S. aureus, P. aeruginosa was the only pathogen able to grow within these human fluids. Expression of typical virulence factors such as pyocyanin and pyoverdine was even enhanced compared the levels seen with standard laboratory medium. A detailed chemical composition analysis of BWE was performed, which enabled us to determine the major components of BWE and underline the metabolic modifications induced by burn trauma. These data are essential for the development of an artificial medium mimicking the burn wound environment and the establishment of an in vitro system to analyze the initial steps of burn wound infections. IMPORTANCE Microbial infection of severe burn wounds is currently a major medical challenge. Of the infections by bacteria able to colonize such injuries, those by Pseudomonas aeruginosa are among the most severe, causing major delays in burn patient recovery or leading to fatal issues. In this study, we investigated the growth properties of several burn wound pathogens in biological fluids secreted from human burn wounds. We found that P. aeruginosa strains were able to proliferate but not those of the other pathogens tested. In addition, burn wound exudates (BWEs) stimulate the expression of virulence factors in P. aeruginosa. The chemical composition analysis of BWEs enabled us to determine the major components of these fluids. These data are essential for the development of an artificial medium mimicking the burn wound

    Oxygen-derived free radicals play important roles in pathophysiological processes in critically ill patients, but the data characterizing relationships between radicals and neuroendocrine system response are sparse. To search the cue to reduce the oxidative cellular damage from the point of view of neuroendocrine system response, we studied the indicators of neuroendocrine and inflammatory responses excreted in urine in 14 burn patients (42.3 +/- 31.4 years old, and 32.3 +/- 27.6% burn of total body surface area [%TBSA]) during the first seven days post burn. The daily mean amounts of urinary excretion of 8-hydroxy-2'-deoxy-guanosine (8-OHdG), a marker of oxidative cellular damage, were above the upper limit of the standard value during the studied period. The total amount of urinary excretion of 8-OHdG in the first day post burn correlated with burn severity indices: %TBSA (r = 0.63, p = 0.021) and burn index (r = 0.70, p = 0.008). The daily urinary excretion of 8-OHdG correlated with the daily urinary excretion of norepinephrine and nitrite plus nitrate (NOx) during the studied period except day 2 post burn, and correlated with the daily urinary excretion of 17-hydroxycorticosteriod (17-OHCS) in days 2, 3, and 7 post burn. These data suggest that oxidative cellular damage correlates with burn severity and neuroendocrine system response modulates inflammation and oxidative cellular damage. Modulation of neuroendocrine system response and inflammation in the treatment in the early phase of burn may be useful to reduce the oxidative cellular damage and to prevent multiple organ failures in patients with extensive burn.

    Prescribed fire has recently been adopted as an encroachment-fighting strategy in the Central Pyrenees. Despite relatively large information on wildfire impacts on soil, there is little information on prescribed fire effects, especially in mountain ecosystems (Shakesby et al, 2015). Fire effects are noticeable in the topsoil, particularly in relation to soil organic matter and nutrient contents and quality (Alexis et al, 2012). These components change with time after fire and at the scale of the upper few centimetres of mineral soil (Badía et al, 2014). The aim of this study is to evaluate the immediate effects of prescribed shrubland burning on soil's nutrients and organic matter content to detect changes at cm-scale, trying to differentiate the heat shock from the subsequent incorporation of ash and charcoal. The study area, densely covered with spiny broom (Echinospartum horridum), is located in Tella (Central Pyrenees, NE Spain) at 1900 meters above sea level. Three sites were sampled before burning and immediately after burning just in its adjacent side. The soils belong to the WRB unit Leptic Eutric Cambisol, Soil samples were collected separating carefully the organic layers (litter in unburned soils and ashes and fire-altered organic residues in burned soils) and the mineral horizon at 0-1, 1-2 and 2-3 cm depths. Soil samples were air-dried and sieved to 2 mm. Soil organic C (by the wet oxidation method), total N (Kjeldahl method), water-soluble ions (Ca2+, Mg2+, Na+, K+, SO4=, NO3- and NH4+), exchangeable ions (Ca2+, Mg2+, K+, Na+, Fe3+ and Mn2+), total and available P, pH (1:5) and the electrical conductivity (in a 1:10 soil-to-water ratio) were measured. Immediately after the controlled fire, soil organic carbon content on burned topsoil decreases significantly within 0-3 cm of soil depth studied while total N decrease was not significant. Moreover, only a slight increase of the electrical conductivity, water-soluble ions and exchangeable ions was

    The Singapore General Hospital (SGH) Burn Centre receives more than 93% of burn cases occurring in Singapore. The Centre also received patients from the Southeast Asian region. The collection and analysis of burn epidemiology data in recent years from Singapore would provide insights into new prevention/management strategies in terms of population profile and economic activities. Data pertaining to burn patients admitted to SGH Burn Centre between January 1997 and December 2003 were studied retrospectively in terms of admissions' demographics, extent of burn (TBSA), causes of burns, length of hospital stay (LOS) and mortality. A total of 2019 burn patients were admitted with an annual admission of 288. This presented an incidence rate for burn injury (with admission) of 0.07 per 1000 general population. The male to female ratio is 2.2:1 and the mean age of admission is 32.5years. The mean extent of burn was 11.5% and patients with burn size 10% TBSA and less made up the majority of admissions at 70.7% while patients with burn size 30% TBSA and more made up 8.2%. The most common cause of burn injury is scald at 45.6% followed by flame at 35.2%. The overall mean LOS and mortality are 10.8days and 4.61%, respectively. An annual trend of falling mortality rate for admissions with burn size >30% TBSA was observed-60% in year 2000 to 30% in 2003. This is a result of massive early excision and grafting of severe burn patients. 17.6% of patients were children of 12years and below, showing a 11.9% reduction from previous study in the 80s. This is consistent with the city's demographics of falling fertility rate and improved living and social conditions. Occupational burn admissions account for 33.4% of total admissions, a reduction of 11.6% from a study in the early 90s. Occurrence of occupational flame burns decreased by 9.5% due to an improvement in fire prevention and management of the industrial sectors. However, chemical burns increased by 12.6% as the chemical sector

    A preliminary assessment is made of the potential role of actinide burning and the Integral Fast Reactor (IFR) in the future of nuclear power. The development of a usable actinide burning strategy could be an important factor in the acceptance and implementation of a next generation of nuclear power. First, the need for nuclear generating capacity is established through the analysis of energy and electricity demand forecasting models which cover the spectrum of bias from anti-nuclear to pro-nuclear. The analyses take into account the issues of global warming and the potential for technological advances in energy efficiency. We conclude, as do many others, that there will almost certainly be a need for substantial nuclear power capacity in the 2000--2030 time frame. We point out also that any reprocessing scheme will open up proliferation-related questions which can only be assessed in very specific contexts. The focus of this report is on the fuel cycle impacts of actinide burning. Scenarios are developed for the deployment of future nuclear generating capacity which exploit the advantages of actinide partitioning and actinide burning. Three alternative reactor designs are utilized in these future scenarios: The Light Water Reactor (LWR); the Modular Gas-Cooled Reactor (MGR); and the Integral Fast Reactor (FR). Each of these alternative reactor designs is described in some detail, with specific emphasis on their spent fuel streams and the back-end of the nuclear fuel cycle. Four separation and partitioning processes are utilized in building the future nuclear power scenarios: Thermal reactor spent fuel preprocessing to reduce the ceramic oxide spent fuel to metallic form, the conventional PUREX process, the TRUEX process, and pyrometallurgical reprocessing.
