    Karen had tons of amazing students, and it's unfortunate that they could not contribute to this collection. They would have a lot of marvelous stories to tell, since they spent so many days and nights at Karen's house, enjoying Bella Artemievna's hospitality and kindness. Karen was a difficult person, with many eccentricities, but at the same time he was very kind and forgiving. When people he knew had troubles, he always did whatever he could to help them. I should add, however, that due to the many tragedies he had experienced in his family life, Karen's threshold for what counted as troubles was unusually high, and what others perceived as major problems struck him as the minor complications of everyday life...

    In her recent article, Hebephilia: Quintessence of Diagnostic Pretextuality (published in Behavioral Sciences and the Law, 2010), Karen Franklin expands on her previous argument that psychologists and psychiatrists should not diagnose as abnormal hebephilia, the sexual preference for early pubescent children. She supports her argument with a series of claims about the contents of the empirical literature and the scientists who produced it. The present document provides fact-checking of those claims, revealing that Franklin's conclusions are based largely on demonstrable falsehoods. PMID:22745581

    1976-01-01

    Karen Quinlan, a young American girl, has lain in hospital since 15 April 1975 without any prospect of recovering consciousness. Her breathing is assisted by means of a respirator and she is fed through a tube inserted in her stomach. Her adoptive parents applied to the courts for permission for the respirator to be switched off. The judge refused permission. Using the Quinlan case as an exemplar, Mr. Kennedy analyses the medical points one by one against the legal background. He would like to see established a code of practice to assist doctors in such cases who at present have no legal guidance. A set of rules arising as a consequence of a series of court decisions would be undesirable; rather a code should be drawn up as the result of discussion between the many people concerned and the consensus so arrived at.

  12. Keystone characteristics that support cultural resilience in Karen refugee parents

    Harper, Susan G.

    2015-08-01

    This participatory action research study used the conceptual framework of social-ecological resilience to explore how Karen (pronounced Ka·rén) refugee parents re-construct cultural resilience in resettlement. The funds of knowledge approach helped to define essential knowledge used by Karen parents within their own community. Framing this study around the concept of resilience situated it within an emancipatory paradigm: refugee parents were actors choosing their own cultural identity and making decisions about what cultural knowledge was important for the science education of their children. Sustainability science with its capacity to absorb indigenous knowledge as legitimate scientific knowledge offered a critical platform for reconciling Karen knowledge with scientific knowledge for science education. Photovoice, participant observation, and semi-structured interviews were used to create visual and written narrative portraits of Karen parents. Narrative analysis revealed that Karen parents had constructed a counter-narrative in Burma and Thailand that enabled them to resist assimilation into the dominant ethnic culture; by contrast, their narrative of life in resettlement in the U.S. focused on the potential for self-determination. Keystone characteristics that contributed to cultural resilience were identified to be the community garden and education as a gateway to a transformed future. Anchored in a cultural tradition of farming, these Karen parents gained perspective and comfort in continuity and the potential of self-determination rooted in the land. Therefore, a cross-cultural learning community for Karen elementary school students that incorporates the Karen language and Karen self-sustaining knowledge of horticulture would be an appropriate venue for building a climate of reciprocity for science learning.

    Since 2004, Minnesota has seen an influx of refugees from Burma. Many of these newcomers came from the Karen state and spent time in refugee camps in Thailand before resettling in the United States. To better understand the health needs of this population, the authors of this article conducted chart reviews at a St. Paul family medicine clinic that serves a number of Karen refugees and reviewed formal data from the Minnesota Department of Health's Refugee Health Program. Here, they briefly describe this community, the cultural issues that could affect health care providers' ability to care for Karen patients, and the health concerns of these refugees.

    Objective To document the prevalence of nutritional deficiencies, infectious diseases and susceptibility to vaccine preventable diseases in Karen refugees in Australia. Design Retrospective audit of pathology results. Setting Community based cohort in Melbourne over the period July 2006–October 2009. Participants 1136 Karen refugee children and adults, representing almost complete local area settlement and 48% of total Victorian Karen humanitarian intake for the time period. Main Outcome Measures Prevalence of positive test results for refugee health screening, with breakdown by age group (<6 years, 6–11 years, 12–17 years, 18 years and older). Results Overall prevalence figures were: anaemia 9.2%, microcytosis 19.1%, iron deficiency 13.1%, low vitamin B12 1.5%, low folate 1.5%, abnormal thyroid function tests 4.4%, vitamin D<50 nmol/L 33.3%, hypocalcaemia 7.4%, raised alkaline phosphatase 5.2%, abnormal liver transaminases 16.1%, hepatitis B surface antigen positive 9.7%, hepatitis B surface antibody positive 49.5%, isolated hepatitis B core antibody positive 9.0%, hepatitis C positive 1.9%, eosinophilia 14.4%, Schistosoma infection 7%, Strongyloides infection 20.8%, malaria 0.2%, faecal parasites 43.4%. Quantiferon-gold screening was positive in 20.9%. No cases of syphilis or HIV were identified. Serological immunity to vaccine preventable diseases was 87.1% for measles, 95% for mumps and 66.4% for rubella; 56.9% of those tested had seroimmunity to all three. Conclusions Karen refugees have high rates of nutritional deficiencies and infectious diseases and may be susceptible to vaccine preventable diseases. These data support the need for post-arrival health screening and accessible, funded catch-up immunisation. PMID:22693599

  6. [Ocular burns].

    Merle, H; Gérard, M; Schrage, N

    Ocular or thermal burns account for 7.7%-18% of ocular trauma. The majority of victims are young. The burns occur in the setting of accidents at work or in the home, or during a physical attack. Chemical burns by strong acids or bases are responsible for the most serious injuries. Associated with the destruction of limbal stem cells, they present as recurrent epithelial ulcerations, chronic stromal ulcers, deep stromal revascularization, conjunctival overlap, or even corneal perforation. The initial clinical exam is sometimes difficult to perform in the presence of burning symptoms. Nevertheless, it enables the physician to classify the injury, establish a prognosis, and most importantly, guide the therapeutic management. The Roper-Hall modification of the Hughes classification system is the most widely utilized, broken down into stages based on the size of the stromal opacity and the extent of possible limbal ischemia. This classification is now favorably supplemented by those proposed by Dua and Wagoner, which are based on the extent of the limbal stem cell deficiency. The prognosis of the more serious forms of ocular burns has markedly improved over the last decade because of a better understanding of the physiology of the corneal epithelium. Surgical techniques aimed at restoring the destroyed limbal stem cells have altered the prognosis of severe corneal burns. In order to decrease the incidence of burns, prevention, particularly in industry, is essential. PMID:18971859

    This case study sought to understand the meaning of restoring traditional weaving as an occupation among Karen women from Burma who now live in an urban city in the United States and to examine the impact of weaving on their daily lives in terms of identity, empowerment, social support, and opportunities for entrepreneurship. The story of one Karen woman, Paw Law Eh, is described. Her story exemplifies the negative consequences of restricted access to familiar and meaningful daily activities, or "occupations", the relationship between occupation and self-identity, how participation in valued occupations can enhance social networks, and the restorative effects that are possible when engagement in meaningful occupations are maintained or restored. Her story demonstrates that occupational therapists have the skills and opportunity to contribute significantly to the well-being of Karen women by supporting the restoration of the occupation of weaving.

    2015-03-01

    This study analyzes the autosomal short tandem repeats (STRs) variation and the presence of Y chromosomal haplogroups from 44 individuals of the Kayah or Red Karen (KA) in Northern Thailand. The results based on autosomal STRs indicated that the KA exhibited closer genetic relatedness to populations from adjacent regions in Southeast Asia (SEA) than populations from Northeast Asia (NEA) and Tibet. Moreover, an admixed origin of the KA forming three population groups was observed: NEA, Southern China, and Northern Thailand. The NEA populations made a minor genetic contribution to the KA, while the rest came from populations speaking Sino-Tibetan (ST) languages from Southern China and Tai-Kadai (TK) speaking groups from Northern Thailand. The presence of six paternal haplogroups, composed of dual haplogroups prevalent in NEA (NO, N, and D1) and SEA (O2 and O3) as well as the intermediate genetic position of the KA between the SEA and NEA also indicated an admixed origin of male KA lineages. Our genetic results thus agree with findings in linguistics that Karenic languages are ST languages that became heavily influenced by TK during their southward spread. A result of the Mongol invasions during the 13th century A.D. is one possible explanation for genetic contribution of NEA to the KA.

    1993-01-01

    Biomass burning may be the overwhelming regional or continental-scale source of methane (CH4) as in tropical Africa and a significant global source of CH4. Our best estimate of present methane emissions from biomass burning is about 51.9 Tg/yr, or 10% of the annual methane emissions to the atmosphere. Increased frequency of fires that may result as the Earth warms up may result in increases in this source of atmospheric methane.

  11. Medicinal plants from swidden fallows and sacred forest of the Karen and the Lawa in Thailand

    PubMed Central

    2013-01-01

    Background Many ecosystem services provided by forests are important for the livelihoods of indigenous people. Sacred forests are used for traditional practices by the ethnic minorities in northern Thailand and they protect these forests that are important for their culture and daily life. Swidden fallow fields are a dominant feature of the agricultural farming landscapes in the region. In this study we evaluate and compare the importance of swidden fallow fields and sacred forests as providers of medicinal plants among the Karen and Lawa ethnic minorities in northern Thailand. Methods We made plant inventories in swidden fallow fields of three different ages (1–2, 3–4, 5–6 years old) and in sacred forests around two villages using a replicated stratified design of vegetation plots. Subsequently we interviewed the villagers, using semi-structured questionnaires, to assess the medicinal use of the species encountered in the vegetation survey. Results We registered a total of 365 species in 244 genera and 82 families. Of these 72(19%) species in 60(24%) genera and 32(39%) families had medicinal uses. Although the sacred forest overall housed more species than the swidden fallow fields, about equal numbers of medicinal plants were derived from the forest and the fallows. This in turn means that a higher proportion (48% and 34%) of the species in the relatively species poor fallows were used for medicinal purposes than the proportion of medicinal plants from the sacred forest which accounted for 17–22%. Of the 32 medicinal plant families Euphorbiaceae and Lauraceae had most used species in the Karen and Lawa villages respectively. Conclusion Sacred forest are important for providing medicinal plant species to the Karen and Lawa communities in northern Thailand, but the swidden fallows around the villages are equally important in terms of absolute numbers of medicinal plant species, and more important if counted as proportion of the total number of species in a

    In the literature no systematic study is available on rescuer burn for victims of burn injury. This is a retrospective study of nine patients (five admitted and four outpatients) were treated in this hospital as rescuer burns in 3.5 years. All nine patients were males. Average age of the patient treated on outpatient basis was 47 years (ranging between 44 and 52) and total burn area ranged for 1-4%. Average age of the five patients treated on inpatient basis was 32.6 years (ranging between 30 and 34). The total burn area ranged from 14.5 to 38%. During the period of study, in addition to nine rescuer burns, one patient sustained burn before the rescue attempt due to the victim hugging the rescuer. Based on the study of patterns of burn, these patients were found to have three grades of burn injury: Grade 1--upper extremity involvement only. (A) only one upper extremity involvement, (B) both upper extremities involvement, Grade 2--upper extremity/extremities and face involvement, Grade 3--upper extremity/extremities, face-neck, adjacent chest and lower extremity involvement.

    Introduction. The key element of a safe workplace for employees is the maintenance of fire safety. Thermal, chemical, and electrical burns are common types of burns at the workplace. This study assessed the epidemiology of work-related burn injuries on the basis of the workers treated in a regional burn centre. Methods. Two years' retrospective data (2005-2006) from the Trauma Registry of the American College of Surgeons of the Joseph M. Still Burn Center at Doctors Hospital in Augusta, Georgia, were collected and analysed. Results. During the time period studied, 2510 adult patients with acute burns were admitted; 384 cases (15%) were work-related. The average age of the patients was 37 yr (range, 15-72 yr). Males constituted the majority (90%) of workrelated burn injury admissions. The racial distribution was in accordance with the Centre's admission census. Industrial plant explosions accounted for the highest number of work-related burns and, relatively, a significant number of patients had chemical burns. The average length of hospital stay was 5.54 days. Only three patients did not have health insurance and four patients (1%) died. Conclusion. Burn injuries at the workplace predominantly occur among young male workers, and the study has shown that chemical burns are relatively frequent. This study functions as the basis for the evaluation of work-related burns and identification of the causes of these injuries to formulate adequate safety measures, especially for young, male employees working with chemicals.

The inappropriate selection or use of PPE can lead to unnecessary exposure or --with extremely hazardous materials--serious harm including death. In 1997, Dr. Karen E. Wetterhahn died from mercury poisoning resulting from a single exposure to dimethylmercury almost a year before. Her death raised numerous questions as to how this tragedy occurred and what could be done to protect against a chemical as dangerous as dimethylmercury. This article provides a brief review of the case and discusses the glove permeation testing done during the course of the accident investigation. Using this case as an example, the author argues that all recommendations for PPE be based on empirical testing using accepted methods and that this information be readily available.

  9. Piloting community-based medical care for survivors of sexual assault in conflict-affected Karen State of eastern Burma

    Background Given the challenges to ensuring facility-based care in conflict settings, the Women’s Refugee Commission and partners have been pursuing a community-based approach to providing medical care to survivors of sexual assault in Karen State, eastern Burma. This new model translates the 2004 World Health Organization’s Clinical Management of Rape Survivors facility-based protocol to the community level through empowering community health workers to provide post-rape care. The aim of this innovative study is to examine the safety and feasibility of community-based medical care for survivors of sexual assault to contribute to building an evidence base on alternative models of care in humanitarian settings. Methods A process evaluation was implemented from July-October 2011 to gather qualitative feedback from trained community health workers, traditional birth attendants, and community members. Two focus group discussions were conducted among the highest cadre health care workers from the pilot and non-pilot sites. In Karen State, eight focus group discussions were convened among traditional birth attendants and 10 among women and men of reproductive age. Results Qualitative feedback contributed to an understanding of the model’s feasibility. Pilot site community health workers showed interest in providing community-based care for survivors of sexual assault. Traditional birth attendants attested to the importance of making this care available. Community health workers were deeply aware of the need to maintain confidentiality and offer compassionate care. They did not raise safety as an excess concern in the provision of treatment. Conclusions Data speak to the promising “feasibility” of community-based post-rape care. More time, awareness-raising, and a larger catchment population are necessary to answer the safety perspective. The pilot is an attempt to translate facility-based protocol to the community level to offer solutions for settings where

    Bleach is a common household product which can cause caustic injuries. Its effects on mucosal tissues and the eye have been well-described in the literature. However, there is little information published regarding the appearance and effect of bleach on a child's skin. We report three children who sustained chemical burns after contact with bleach. All three children sustained accidental bleach burns while at home, and each child had a distinct brown discoloration to the skin from the injury. All three children had treatment and follow-up for their burns. Two of the children sustained more severe burns, which were extensive and required more time to heal. There was also long-term scarring associated with the severe burns. Like most burns, pain control is required until the injury heals.

There is presented experience with the selected group of 24 patients in whom the diagnosis of burn was associated with epilepsy. There is also analysed and described the gravity of the scars sequels, neurological disorders, the complication of the burn and an impact of this problem on the patient, his (her) family and the community. It is very important to report that there was found Neurocisticercosis in 66.6% of the group of burn patients with epilepsy, and it is probably the first risk factor of burn in this group.

    Cauterization of the skin by a red-hot iron, a pinch of hot cinder or a burning coal, is a form of 'treatment' used by lay healers in some parts of Africa and the Middle East. The burns are limited to small circular areas, and are usually full-thickness skin loss. Most frequently, the patients do not seek medical treatment and the burns heal by secondary intention. Sometimes, however, disastrous complications such as infectious osteomyelitis, septicaemia and death may occur.

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

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

  16. Burns and military clothing.

    2001-02-01

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

    A solid fuel burning stove includes a firebox having an insulated bottom chamber in which fuel is burned. The bottom chamber includes an insulated bottom surface and walls which provides for heat retention when fuel is burn therein thereby creating high temperatures. The bottom chamber of the firebox is divided from a top chamber by a horizontally extending baffle which directs flow of exhaust gases from the bottom to the top of the firebox. The exhaust gases are burned in the top portion of the firebox by means of the heat generated within the lower chamber and the introduction of fresh combustion air. This fresh combustion air is drawn in through an orificed pipe extending along the length of the firebox. After the gases are burned in the top portion of the stove, they are communicated to a heat saver including an inverted v-shaped flow diverter which reduces the velocity of the exiting gases and provides for greater recovery of heat therefrom. The stove in accordance with the invention provides for a two-stage burning process wherein solid fuel is burned in the first stage and the volatile gases released by the fuel are burned in the second stage. In this way, the fuel is consumed in a most efficient manner.

    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.

    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.

The most serious burns followed work-related accidents, with a fatal outcome in 47 per cent of the patients. The serious burns are usually deep dermal or full skin thickness. A common pattern affects groins, genitalia, hypogastrium and hands, and are produced when fireworks ignite in the pockets of the patient's trousers. The management of these lesions does not differ from burns caused by other agents, although attention should be paid to the presence of associated lesions, chiefly to eyes, ears and hands, due to the shockwave and shrapnel.

    In this chapter the local therapy for burns is discussed. Between 400 and 500 children with burns are treated every year at the Red Cross War Memorial Children's Hospital in Cape Town, but in only 10% of them do the burns affect over 20% of the body surface. These latter patients are treated in special rooms equipped for intensive therapy. Open and closed methods of treatment for burns used in addition to early excision are compared. The first aim is early skin cover for areas with skin loss preserving as much function as possible and achieving the best possible cosmetic result. Local therapy must be atraumatic to prevent extension of the skin lesion. Bacterial contamination must be prevented as far as possible by keeping the wound clean. Emergency treatment and the course of wound healing up to the third week after the injury using the appropriate dressings are described. Early excision until the fifth day after the accident should be used mainly for burns of the hand, deep second degree burns of up to 10% of the body surface, deep second degree burns over the joints and deep second degree burns of the neck. It must be admitted that the depth of the burn can only be definitely estimated between the seventh and tenth day after the accident. If no autografts are available homografts or grafts from animals are used. The age of the patient, associated injuries, associated diseases and the extent of the burn all play a role in determining the prognosis. Furthermore endogenous bacterial infections, absorption of local therapeutic agents and the state of the surrounding skin do also influence the healing process. Finally the various local therapeutic agents like sulphamylon, silver sulphadiazine and betadine are discussed. A 0.05% solution of silver nitrate is also active against gram-negative infections. Skin transplants are disinfected with a solution containing one third 0.25% acetic acid, one third 3% cent hydrogen peroxide and one third saline. Hydrogen peroxide

    The authors have analyzed the data files of 580 child patients up to 15 years of age who were hospitalized at the Burn Center of the FNsP Hospital in Ostrava in the years 1999 - 2003. The authors focused on mechanisms of burn injury in relation to the age of a child as well as extent, depth, localization, and local treatment of the injury. The data file was divided to four age groups: up to two years of age, 2 - 5 years of age, 5 - 10 years of age, and 10 - 15 years of age. As regards the mechanisms of injury, the authors have analyzed scalding by hot liquids, burns due to contact with a hot object, burns due to electric current, explosion, and injury caused by burning clothing. Injury by scalding prevails to a very significant degree in the youngest children. In the second age group the incidence of burn following contact with hot objects increases, as does the percentage of children injured by burning of clothing in children aged 5 - 10. The older children have increased prevalence of injuries caused by explosions. The greatest average extent of an injury is from burning of clothing. Most of the areas are burned deeply, localized in more areas of the body, and almost half of the cases required surgical intervention. Scalding comes second in terms of average extent of an injury. More than half of the injured areas are superficial, and areas of injury are different in the individual age groups. We addressed about a fifth of the cases surgically. The explosion of combustible materials caused a smaller extent of injury, on average, taking third place. The injuries were predominantly superficial, most commonly involving the head, trunk, and upper extremities. In none of the cases it was necessary for us to operate. Burn injuries caused by contact with hot objects are of a smaller extent. More than half of the burned areas are deep, localized most commonly in the upper extremities. Surgical intervention was necessary in more than half the cases. In terms of average

    Determination of burn wound depth is at present left to the surgeons visual examination. Many burn wounds are obviously, by visual inspection, superficial 2 degree burns or true 3 degree burns. However, those burn wounds that fall between the obvious depth burns are difficult to assess visually, and therefore wound depth determination often requires waiting 5 to 7 days postburn. Initially, 10 burn patients underwent IR imaging at various times during the evaluation of their burn wounds. These patients were followed to either healing or skin grafting. The IR images were then reviewed to determine their accuracy in determining the depth of the wound. IR imaging of burn wounds with focal plane staring array midrange IR systems appears promising in determination of burn depth one to two days postburn. This will allow clinical decision regarding operative or nonoperative intervention to be made earlier, thus decreasing hospital stays and time to healing.

    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.

    The purpose of this report is to increase awareness of intraoperative burns during standard procedures, to discuss their possible causes and warning signs and to provide recommendations for prevention and procedures to follow after their occurrence. A total of 19 patients associated with intraoperative burn accidents were treated surgically and analyzed after a mean follow-up of 5 +/- 3.5 months. Review included retrospective patient chart analysis, clinical examination, and technical device and equipment testing. A total of 15 patients recently underwent cardiac surgery, and 4 pediatric patients recovered after standard surgical procedures. A total of 15 patients had superficial and 4 presented with deep dermal or full-thickness burns. The average injured TBSA was 2.1 +/- 1% (range, 0.5-4%). Delay between primary surgery and consultation of plastic surgeons was 4.5 +/- 3.4 days. A total of 44% required surgery, including débridment, skin grafting or musculocutaneous gluteus maximus flaps, and the remaining patients were treated conservatively. Successful durable soft-tissue coverage of the burn region was achieved in 18 patients, and 1 patient died after a course of pneumonia. Technical analysis demonstrated one malfunctioning electrosurgical device, one incorrect positioned neutral electrode, three incidents occurred after moisture under the negative electrode, eight burns occurred during surgery while fluid or blood created alternate current pathways, five accidents were chemical burns after skin preparation with Betadine solution, and in one case, the cause was not clear. The surgical team should pay more attention to the probability of burns during surgery. Early patient examination and immediate involvement of plastic and burn surgeons may prevent further complications or ease handling after the occurrence.

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

    This research program successfully developed a real-time video imaging system (the Imaging Burn Depth Indicator, or IBDI) which can discriminate areas of burn wounds expected to heal in three weeks or less from the day of injury from those areas not expected to heal in that time period. The analysis can be performed on or about the third day post-burn on debrided burn wounds. Early evaluation of burn healing probability is a crucial factor in the decision to tangentially excise the burn wound. The IBDI measures the reflectivity of the burn wound in the red, green, and near infrared wavelength bands, which data correlate with burn healing probability. The instrument uses an algorithm established in an earlier study to translate the optical data into burn healing probabilities. The IBDI produces two types of images: a true-color image of the burn and a false-color image of the burn. The false-color image consists of up to four colors, each of which indicates a distinct range of probability that the area of the burn so colored will heal within 21 days. Over 100 burn wound sites were studied. Burn sites were evaluated on day three post-burn by our instrument and by the attending physician. Of 55 sites considered to be of intermediate depth, the IBDI predicted the healing outcome accurately in 84% of the cases. By comparison, the predictions of burn surgeons supervising the care of these patients were accurate in 62% of the cases.

  20. The media glorifying burns: a hindrance to burn prevention.

    The media have a profound influence on the actions of children and adults. Burns and burn prevention tend to be ignored or even mocked. The purpose of this presentation is to reveal the callousness of the media in its dealings with burns and burn prevention. Printed materials with a relationship to burns, risk of burning, or disrespect for the consequences of burns were collected. The materials were tabulated into four categories: comics, advertisements (ads), articles that made light of burns, and television shows that portrayed behavior that would risk burn injury. Most burn-related materials were found in comics or advertisements. Several comics made light of high-risk behavior with flames, scald injury, contact injury, or burns. In addition, several advertisements showed people on fire or actions that could easily lead to burns. Several articles and televisions shows portrayed high-risk behavior that, in some instances, led to copycat injuries. Flames are frequently used to sell items that target adolescent boys or young men. The high incidence injuries that frequent this population parallel the high-risk behaviors portrayed by the media. The media portrays flames and high-risk behavior for burn injury as being cool, funny, and without consequence. The use of flames on clothing and recreational equipment (skateboards, hot rods) particularly targets the high-risk adolescent male. The burn community should make the media aware of the harm it causes with its callous depiction and glorification of burns.

    Phenol burns and intoxications are life-threatening injuries. Roughly 50 per cent of all reported cases have a fatal outcome. Only a small number of cases have been reported with high serum concentrations after phenol burns who survived. In our own experience a patient with 20.5 per cent total body surface area deep partial skin thickness phenol burns and serum concentrations of 17,400 micrograms/litre survived after immediate and repeated treatment of the scalds with polyethylene glycol (PEG) and silver sulphadiazine. A literature review of experiences with phenol intoxications reveals the advantages of PEG application. Questions on the need for enforced diuresis and haemodialysis as well as the initial treatment procedures are discussed. Advantages of different solutions for local therapy are reported.

    Most burning of biomass is the result of human activity, and on a global scale it is increasing. Tropospheric concentrations of CO2, CO, CH4, non-methane hydrocarbons, and ozone are all increasing with time; global biomass burning may make an important contribution to this increase and thus to potential global climate change. The nitrogen cycle also can have important climatic effects. Nitrous oxide put into the atmosphere by biomass burning is a greenhouse gas 250 times more powerful (molecule for molecule) than carbon dioxide. Nitric oxide, as well as being a photochemical precursor of ozone, a major pollutant in the troposphere, produces nitric acid, the fastest-growing component of acid rain. Hence, the new bridge in the nitrogen cycle is of more than mere technical interest.

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

  6. Management of acute burns and burn shock resuscitation.

    PubMed

    Faldmo, L; Kravitz, M

    1993-05-01

    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

    A 50-year-old man presented with a 2-day history of bilateral lower extremity cramping and dark urine. The patient was found to have a creatine phosphokinase (CPK) elevated of up to 2306 U/L, a serum uric acid of 9.7 mg/dL and 101 red blood cell's per high-powered field on urinalysis. On questioning, the patient endorsed daily exercise with free weights. There were no changes in his regular exercise and medication regimen, no muscle trauma, no recent drug use and no illness. The patient did mention using a new fat burner known as 'Fat Burn X', which he had begun taking 2 days prior to the onset of his muscle cramps. The patient was given normal saline intravenous fluid resuscitation for 48 h with resultant normalisation of his CPK and creatinine, and was discharged with primary care follow-up.

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

    Significance: While the survival rate of the severely burned patient has improved significantly, relatively little progress has been made in treatment or prevention of burn-induced long-term sequelae, such as contraction and fibrosis. Recent Advances: Our knowledge of the molecular pathways involved in burn wounds has increased dramatically, and technological advances now allow large-scale genomic studies, providing a global view of wound healing processes. Critical Issues: Translating findings from a large number of in vitro and preclinical animal studies into clinical practice represents a gap in our understanding, and the failures of a number of clinical trials suggest that targeting single pathways or cytokines may not be the best approach. Significant opportunities for improvement exist. Future Directions: Study of the underlying molecular influences of burn wound healing progression will undoubtedly continue as an active research focus. Increasing our knowledge of these processes will identify additional therapeutic targets, supporting informed clinical studies that translate into clinical relevance and practice. PMID:26989577

    Currently a large proportion of patients with severe burn injuries survive. This gives increasing challenges also for psychological recovery after the trauma. More than half of burn patients have mental disorders already before the burn injury but also patients who previously had no mental disorders may suffer from them. Some of the hospitalize burn patients have injuries due to suicidal attempts. Only a small proportion of burn patients receive appropriate psychiatric care although psychosocial interventions specifically planned for burn victims exist. More frequent screening of symtoms of mental disorders and psychiatric consultation, also after acute care in hospital, could lead to better management of post-burn psychiatric care as well as better management of the burn treatment and rehabilitation itself.

    Vitamin A deficiency (VAD) is the most common cause of childhood blindness in the developing world. It is estimated that by giving adequate vitamin A, in vitamin A deficient populations, child mortality from measles can be reduced by 50%, and mortality from diarrheal disease by 40%. Overall mortality in children 6-59 months of age can be reduced by 23%. This paper reported results from a study of vitamin A status and malnutrition of the minority ethnic group of Karen hill tribe children aged 1-6 years in the north of Thailand. All children aged 1-6 years (N = 158; 83 boys, 75 girls) from the three Karen villages (Mae Hae Tai, Mae Yot, Mae Raek) of Mae Chaem district in the north of Thailand were studied. The Karen is the largest mountain ethnic minority ("hill tribe") group in Thailand. All children were examined by a qualified medical doctor and were assessed for their vitamin A intakes using 24 hours dietary recall. Thai food composition table from Ministry of Health, Thailand were used as references. The results were compared with the Thai Recommended Dietary Allowances. Children aged 1-3 years and 4-6 years were separately analysed due to the differences in Thai Recommended Dietary Allowances between the two age groups. A whole blood of 300 microL was obtained by "fingerstick" for determination of serum vitamin A. Community or village's vitamin A status was assessed by using Simplified Dietary Assessment (SDA) method and Helen Keller International (HKI) food frequency method. Descriptive statistics were used to analyse the data. All families of the study boys and girls had income lower than the Thailand poverty line (US $ 1,000/year). On average, 63% of children from Mae Hae Tai village, 1.5% of children from Mae Yot village and none of children from Mae Raek village had serum vitamin A<0.7 micromol/L which indicated VAD. All boys and only girls from Mae Raek village consumed vitamin A more than the Thai RDA but girls from Mae Hae Tai village and Mae Yot

    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.

    The ecological effects of forest fires burning with high severity are long-lived and have the greatest impact on vegetation successional trajectories, as compared to low-to-moderate severity fires. The primary drivers of high severity fire are unclear, but it has been hypothesized that wind-driven, large fire-growth days play a significant role, particularly on large fires in forested ecosystems. Here, we examined the relative proportion of classified burn severity for individual daily areas burned that occurred during 42 large forest fires in central Idaho and western Montana from 2005 to 2007 and 2011. Using infrared perimeter data for wildfires with five or more consecutive days of mapped perimeters, we delineated 2697 individual daily areas burned from which we calculated the proportions of each of three burn severity classes (high, moderate, and low) using the differenced normalized burn ratio as mapped for large fires by the Monitoring Trends in Burn Severity project. We found that the proportion of high burn severity was weakly correlated (Kendall τ = 0.299) with size of daily area burned (DAB). Burn severity was highly variable, even for the largest (95th percentile) in DAB, suggesting that other variables than fire extent influence the ecological effects of fires. We suggest that these results do not support the prioritization of large runs during fire rehabilitation efforts, since the underlying assumption in this prioritization is a positive relationship between severity and area burned in a day.

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

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.

    Introduction Superficial burns that affect the epidermis and upper dermis only are characterised by redness of the skin that blanches on pressure, pain, and hypersensitivity. The skin blisters within hours and usually heals with minimal scarring within 2 to 3 weeks if no infection is present. Most minor burns occur in the home, with less than 5% requiring hospital treatment. Methods and outcomes We conducted a systematic review and aimed to answer the following clinical question: What are the effects of treatments for minor thermal burns? We searched: Medline, Embase, The Cochrane Library, and other important databases up to October 2008 (Clinical Evidence reviews are updated periodically; please check our website for the most up-to-date version of this review). We included harms alerts from relevant organisations such as the US Food and Drug Administration (FDA) and the UK Medicines and Healthcare products Regulatory Agency (MHRA). Results We found eight systematic reviews, RCTs, or observational studies that met our inclusion criteria. We performed a GRADE evaluation of the quality of evidence for interventions. Conclusions In this systematic review, we present information relating to the effectiveness and safety of the following interventions: alginate dressing; antibiotics; chlorhexidine-impregnated paraffin gauze dressing; foam dressing; hydrocolloid dressing; hydrogel dressing; paraffin gauze dressing; polyurethane film; silicone-coated nylon dressing; and silver sulfadiazine cream.

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

Each year, more burned children are necessitating serious medical attention during their convalescence. For children with serious consequences resulting from burns that can persist from childhood through adolescence into adulthood, the value of long-term rehabilitation cannot be over stated. Burn injury management should not focus only on the immediate treatment. Long-term functional outcome and the required rehabilitation that burn victims must go through should be given equal if not more attention. The present is a review of the available modalities utilized for the physical rehabilitation of convalescent pediatric burns in order to overcome the catabolic state, improve muscle power and fitness, reduce disfiguring scars and prevent contractures.

    In this paper a new system for burn diagnosis is proposed. The aim of the system is to separate burn wounds from healthy skin, and the different types of burns (burn depths) from each other, identifying each one. The system is based on the colour and texture information, as these are the characteristics observed by physicians in order to give a diagnosis. We use a perceptually uniform colour space (L*u*v*), since Euclidean distances calculated in this space correspond to perceptually colour differences. After the burn is segmented, some colour and texture descriptors are calculated and they are the inputs to a Fuzzy-ARTMAP neural network. The neural network classifies them into three types of bums: superficial dermal, deep dermal and full thickness. Clinical effectiveness of the method was demonstrated on 62 clinical burn wound images obtained from digital colour photographs, yielding an average classification success rate of 82% compared to expert classified images.

    Burning mouth syndrome (BMS) is an enigmatic, misunderstood, and under-recognized painful condition. Symptoms associated with BMS can be varied, thereby providing a challenge for practitioners and having a negative impact on oral health-related quality of life for patients. Management also remains a challenge for practitioners because it is currently only targeted for symptom relief without a definitive cure. There is an urgent need for further investigations to determine the efficacy of different therapies because this is the only way viable therapeutic options can be established for patients with this chronic and painful syndrome.

    SystemBurn is a tool for creating a synthetic computational load for the purpose of measuring how much power a computer will draw under that type of load. The loads include fundamental library function calls like matrix multiply, memory copies, fourier transforms, bit manipulation, I/O, network packet transfers, and some code contrived to cause the processor to dray more or less power. The code produces some diagnostic and progress output, but the actual measurements would be recorded from the power panels within the computer room.

    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

    Obstetric complications may result from burn scarring in the genital area. Women in developing countries typically squat around cooking fires, and burns are common. This recent case in Nepal describes obstructed labor in a young woman whose genital area had extensive scarring from a cooking fire injury. Proper antenatal assessment by health care providers can reduce the risk to mothers and infants of the consequences of a birth canal damaged or obstructed by burn scarring.

    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.

    Flame deriving from paint thinner is not a rare cause of burns in Morocco and we thus considered it useful to conduct an epidemiological survey of paint thinner flame burns (PTFB) in the National Burns Centre (NBC) in the Ibn-Rochd University Hospital Centre in Casablanca, Morocco. The research covered the 10-month period from September 2007 to June 2008.The aim of our work was to present the characteristic features of such burns in order to prevent them by increasing public knowledge regarding the risks involved in using paint thinner, i.e. burns in particular. During the period in question, we colligated 17 cases of PTFB out of a total number of 356 patients admitted to the NBC for acute burns of all aetiologies. The patients' average was 32 yr and they were nearly all male (16 men/1 woman), with past histories of drug addiction and/or delinquency. They were all of low-level socioeconomic class and lived mainly in shanty towns. The burn was often secondary to street violence (92% of the cases).The mean burn surface area was 23% and the burns were often deep and located mainly in the upper limbs and the trunk. PMID:21991179

  11. Global Burned Area and Biomass Burning Emissions from Small Fires

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

    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.

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

    A wood-burning stove includes side walls joined together in an airtight manner to form a firebox and a heat chamber thereabove. The firebox contains upstanding rails to support wood logs for combustion. Streams of heated air are discharged from a manifold that extends from rail-to-rail outwardly from one terminal end of each rail between opposite side walls of the stove. A plate is adjusted to control the flow of air into the manifold. An access door has openings in a spacer side wall for supplying air as desired to the firebox. The spacer walls of the door support a glass panel at an outwardly spaced location from a deflector to prevent deposits of creosote and other materials on the glass.

    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.

    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 PMID:21321643

Ancient Egyptians did not know about microorganisms but they knew that honey, moldy bread and copper salts could prevent infections from dirt in burns healing. Thyme, opium and belladona were used for pain relief. In the 4th century BC, Hippocrates recorded that Greek and Roman doctors used rendered pig fat, resin and bitumen to treat burns. Mixture of honey and bran, or lotion of wine and myrrh were used by Celsus. Honey was also known in Ayurveda (Indian medicine) time. Ayurvedic records Characa and Sushruta included honey in their dressing aids to purify sores and promote the healing. Burn treatment in Chinese medicine was traditional. It was a compilation of philosophy, knowledge and herbal medicine.

    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.

    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.

    Colloids have been used in varying capacities throughout the history of formula-based burn resuscitation. There is sound experimental evidence that demonstrates colloids' ability to improve intravascular colloid osmotic pressure, expand intravascular volume, reduce resuscitation requirements, and limit edema in unburned tissue following a major burn. Fresh frozen plasma appears to be a useful and effective immediate burn resuscitation fluid but its benefits must be weighed against its costs, and risks of viral transmission and acute lung injury. Albumin, in contrast, is less expensive and safer and has demonstrated ability to reduce resuscitation requirements and possibly limit edema-related morbidity. PMID:27600123

    The deep burns of the face can lead to horrible scars functionally and aesthetically. Treatment of these scars need several surgical interventions frequently and during many years. 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.

    Nowadays burn patients who also have periocular symptoms are usually treated by reconstructive surgeons and the role of the ophthalmic surgeon has decreased.Although periocular complications occur in a minority of burned patients, they pose a greater challenge in surgical and non-surgical treatment. Chemical, electrical and thermal burns can lead to disfiguring scar formations and delayed treatment can lead to devastating ocular complications. Achieving a successful reconstruction requires a comprehensive approach, entailing many advanced techniques with an emphasis on preserving function and balancing intricate aesthetic requirements. The theory is illustrated in this article with clinical examples. PMID:23345146

    The Structure of Flameballs at Low Lewis Numbers (SOFBALL) experiments aboard the space shuttle in 1997 a series of sturningly successful burns. This sequence was taken during STS-94, July 12, 1997, MET:10/08:18 (approximate). It was thought these extremely dim flameballs (1/20 the power of a kitchen match) could last up to 200 seconds -- in fact, they can last for at least 500 seconds. This has ramifications in fuel-spray design in combustion engines, as well as fire safety in space. The SOFBALL principal investigator was Paul Ronney, University of Southern California, Los Angeles. The experiment was part of the space research investigations conducted during the Microgravity Science Laboratory-1R mission (STS-94, July 1-17 1997). Advanced combustion experiments will be a part of investigations planned for the International Space Station.

    1988-07-01

    In an old Pennsylvania coal valley, growing fresh produce and eliminating ancient waste piles both depend on a fluidized bed boiler cogeneration plant. The builders of a complex now nearing completion at Archbald, however, will soon begin to turn two of the waste piles, called culm banks, into economic assets. Culm will burn although it has a low, variable heat content. The project combines several recently developed technologies to use culm as fuel for a fluidized bed boiler cogeneration plant that will heat a hydroponic greenhouse. What makes the venture economically viable are the products that will be sold: 23 mw of electricity to the local utility and fresh produce to meet burgeoning demands in East Coast supermarkets. For instance, if the ''salad plant'' were completely devoted to growing lettuce, 3 million heads could be harvested in 11 hydroponic seasons a year. The owners, Archbald Power Corp., chose a 271 acre stie that had been mined for anthracite by both open pit and deep shaft methods.

    To fix and make the nation's Superfund law work, two related questions must be answered. First, where will the innovative technology come from the clean up Superfund and other waste sites Burning dirt--the best technology currently available--is an expensive nonsolution. Second, can man muster the political will to make Superfund a waste cleanup law instead of an expanding welfare program for lawyers Under the sponsorship of EPA, a number of companies and other groups are participating in the Remediation Technology Development Forum, focusing on the areas where the real breakthroughs might occur and the most promising collaborations. Currently, this effort is focused on bioremediation, the lasagna process, soil flushing, and characterization. Another area of investigation is stabilization technology--stabilizing a site to keep contaminants from flowing away. Some scientists, for example, are looking at vitrification technology, which fuses contaminated soil into a glass-like brick. And still other technology efforts include air flushing of contaminated sites and vapor extraction and heating processes. A number of groups and consortia have been working on waste remediation technologies. For the first time since 1980, when Superfund became law, one can give positive answers to the two critical questions. Groups are finding innovative technologies to clean up Superfund and other waste sites. And, as a nation, Americans are exercising the political will to create a Superfund law that will work effectively and fairly.

  20. Hair dryer burns in children.

    PubMed

    Prescott, P R

    1990-11-01

    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.

    Chemical burns continue to pose a variety of dilemmas to the clinician managing such cases. Assessment of burn depth is often difficult and the decision whether to excise the wound early is not always clear-cut. In this updated review, common agents are classified and the basic principles of management and specific recommendations are examined. The complications arising from exposure to these chemicals and the supportive measures needed during treatment are also described.

  2. 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.

  3. Burn treatment in the elderly.

    2009-12-01

    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.

    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. Images Figure 2 Figure 3 PMID:8268745

    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.

    1991-04-01

    The Resource Conservation and Recovery Act (RCRA) was designed to ensure that incineration facilities which treat hazardous wastes operate in an environmentally responsible manner. Under the requirements of RCRA, a trial burn must be conducted in order to obtain a fmalized operating permit. A trial burn is a test which determines whether an incinerator is capable of meeting or exceeding RCRA performance standards. If the standards are met, then the trial burn should identify the operating conditions necessary to ensure the incinerator's ability to meet or exceed the performance standards throughout the life of the permit. Development of the trial burn must incorporate interests of both the permit writer and the applicant. The permit writer wishes to obtain sufficient data necessary to establish the final permit conditions. The applicant wishes to obtain a final permit which allows the greatest flexibility of incinerator operating parameters. The areas of interest to be discussed, which allow the applicant and permit writer to achieve their goals, include understanding the problem, selecting a waste feed, choosing the principal organic hazardous constituents (POHCs), determining operating conditions, choosing appropriate sampling methods, and obtaining representative samples (QAIQC). The purpose of this paper is to give an overview of what is required to develop a trial burn plan.

    Because a large amount of general aviation activity occurs in Central Florida, we reviewed our admissions for victims of small airplane crashes. We identified 13 burn victims of small aircraft accidents over a 7-year period. Of the 13, 12 survived their burn injuries, an overall survival rate of 92%. The extent of burn injury, Abbreviated Burn Severity Index (ABSI), complications, other injuries and rehabilitation potential are reviewed. Burn injury resulting from small airplane crashes is usually survivable if the patient arrives at the Burn Center alive. These burn victims generally are highly motivated individuals, are easily rehabilitated, and continue productive lives. Small airports and local hospitals should be aware of burn center availability because of the usual major extent of the burn injury.

    Questions of the importance and feasibility of performing experiments on droplet burning at zero gravity in Spacelab were studied. Information on the physics and chemistry of droplet combustion, with attention directed specifically to the chemical kinetics, heat and mass transfer, and fluid mechanics of the phenomena involved, are presented. The work was divided into three phases, the justification, the feasibility, and the conceptual development of a preliminary design. Results from the experiments performed revealed a few new facts concerning droplet burning, notably burning rates in excess of theoretical prediction and a phenomenon of flash extinction, both likely traceable to accumulation of carbon produced by gas-phase pyrolysis in the fuel-rich zone enclosed by the reaction surface. These experiments also showed that they were primarily due to timing difficulties.

    A fuel burning stove is claimed for holding and burning fuel to heat the surrounding atmosphere in a room where the stove is employed. The stove includes a fire box which supports the fuel and where the combustion is sustained. An air inlet is provided to the fire box allowing the inflow of air for combustion with the fuel. The air is preheated upon entry into the fire box for mixture with volatiles formed by the burning fuel directed toward the entering air by a baffle means to effect a secondary combustion. In addition, a movable damper cooperates with the baffle to direct volatiles toward the incoming heated air when the damper is in the closed position and to provide a more direct path to the chimney when in the open position.

    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.

    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

    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.

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.

    The report describes a patient with 45 per cent BSA burns who developed Legionnaire's disease 3 days after the acute injury. The diagnosis of this life-threatening complication was late because most of its signs and symptoms can be encountered in the burned patient. This delay could have been fatal to the patient and required the evacuation of the burn centre for disinfection.

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

    In her thoughtful review and synthesis, Karen Gubb overstimates the breadth of resurgent interest among psychoanalysts in psychosomatic medicine. Such a modest revival as there has been reflects primarily the activity of a few authors and editors. Still, after several decades of inactivity following the intense excitement about this subject during the 1940s and 1950s, there has been some renewal of interest, primarily in Europe and among a small group in the United States. The golden age of psychoanalytic psychosomatics came to an end with the failure to find evidence in support of the promising but overly simplistic specificity theories, especially those of Franz Alexander. If we were going to better understand the complex relations between bodily states (including illnesses) and mental phenomena new theories and modes of investigation would be required. Many apparently new theories have been put forward over the past few decades. Of these, Gubb focuses her attention on two that relate somatic illness to failures in linguistic or symbolic elaboration, that is, to failures in the working over or binding of somatic excitations by the mental apparatus. These theories share the attractive feature that they seem consistent with the claim that psychosomatically ill patients are impaired in their language capacities, being unable to put feelings into words (alexithymia) and unable to move to abstract from concrete thinking (pensée opératoire). While apparently new, when closely examined these theories turn out to be but minor variations of one of Freud's own fundamental theories of mind/body, the one explicated in The Interpretation of Dreams and based upon the neurological model of the reflex arc as known in the 19th century.

    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.

    Burn injuries pose complex biopsychosocial challenges to recovery and improved comprehensive care. The physical and emotional sequelae of burns differ, depending on burn severity, individual resilience, and stage of development when they occur. Most burn survivors are resilient and recover, whereas some are more vulnerable and have complicated outcomes. Physical rehabilitation is affected by orthopedic, neurologic, and metabolic complications and disabilities. Psychiatric recovery is affected by pain, mental disorders, substance abuse, and burn stigmatization. Individual resilience, social supports, and educational or occupational achievements affect outcomes.

    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

    This invention, a method for ultrasonically determining the depth of a skin burn, is based on the finding that the acoustical impedance of burned tissue differs sufficiently from that of live tissue to permit ultrasonic detection of the interface between the burn and the underlying unburned tissue. The method is simple, rapid, and accurate. As compared with conventional practice, it provides the important advantage of permitting much earlier determination of whether a burn is of the first, second, or third degree. In the case of severe burns, the usual two - to three-week delay before surgery may be reduced to about 3 days or less.

    The quest for a year round tan has led to an increase in the use of artificial tanning devices, namely sunbeds. There has been much debate in the press recently regarding the dangers of sunbed use and calls for tighter regulation of the industry, particularly the licensing of unmanned tanning salons. The dangers of sunbed use have long been recognised and the body of evidence linking sunbed use to skin malignancy is growing, in fact this month the Lancet published a review from the International Agency for Research on Cancer classifying UV emitting tanning devices as carcinogenic to humans. At the Welsh Centre for Burns and Plastic Surgery we noticed a rise in the number of patients presenting with burns related to sunbed use and present our data surrounding this injury over the last 6 years.

    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

    Background Despite reported declines, occupational burn injuries remain a workplace safety concern. More severe burns may result in costly medical treatment and long-term physical and psychological consequences. Methods We used the National Electronic Injury Surveillance System—Occupational Supplement to produce national estimates of burns treated in emergency departments (EDs). We analyzed data trends from 1999 to 2008 and provided detailed descriptions of 2008 data. Results From 1999 to 2008 there were 1,132,000 (95% CI: ±192,300) nonfatal occupational burns treated in EDs. Burn numbers and rates declined approximately 40% over the 10 years. In 2008, men and younger workers 15–24 years old had the highest rates. Scalds and thermal burns accounted for more than 60% of burns. Accommodation and food service, manufacturing, and construction industries had the largest number of burns. Conclusions Despite declining burn rates, emphasis is needed on reducing burn hazards to young food service workers and using job specific hazard analyses to prevent burns. PMID:25678457

    The care provided to the victims of burn injury immediately after sustaining burns can largely affect the extent and depth of the wound. Although standard guidelines have been formulated by various burn associations, they are still not well known to public at large in our country. In burn injuries, most often, the bystanders are the first care providers. The swift implementation of the measures described in this article for first aid in thermal, chemical, electrical and inhalational injuries in the practical setting, within minutes of sustaining the burn, plays a vital role and can effectively reduce the morbidity and mortality to a great extent. In case of burn disasters, triage needs to be carried out promptly as per the defined protocols. Proper communication and transport from the scene of the accident to the primary care centre and onto the burn care facility greatly influences the execution of the management plans PMID:21321651

    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.

    An interactive, video game-based training module, Burn Center, was developed to simulate the real-life emergency events of a mass casualty disaster scenario, involving in 40 victims.The game contains two components - triage and resuscitation. The goal of the triage game is to correctly stabilize, sort, tag and transport burn victims during a mass casualty event at a busy theme park. After complete the triage component, the player will then take on the role of a burn care provider, balancing the clinical needs of multiple burn patients through a 36-hour resuscitation period, using familiar computer-simulated hospital devices. Once complete, players of Burn Center will come away with applicable skills and knowledge of burn care, for both field triage and initial resuscitation of the burn patients. PMID:19377134

    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.

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

  5. Atmospheric Effects of Biomass Burning

    Biomass fires are both natural and anthropogenic in origin. The natural trigger is lightning, which leads to mid- and high-latitude fires and episodes of smoke and pollution associated with them. Lightning is also prominent in tropical regions when the dry season gives way to the wet season and lightning in convective systems ignites dry vegetation. Atmospheric consequences of biomass fires are complex. When considering the impacts of fires for a given ecosystem, inputs of fires must be compared to other process that emit trace gases and particles into the atmosphere. Other processes include industrial activity, fires for household purposes and biogenic sources which may themselves interact with fires. That is, fires may promote or restrict biogenic processes. Several books have presented various aspects of fire interactions with atmospheric chemistry and a cross-disciplinary review of a 1992 fire-oriented experiment appears in SAFARI: The Role of southern African Fires in Atmospheric and Ecological Environments. The IGAC/BIBEX core activity (see acronyms at end of Chapter) has sponsored field campaigns that integrate multiple aspects of fires ground-based measurements with an ecological perspective, atmospheric measurements with chemical and meteorological components, and remote sensing. This Chapter presents two aspects of biomass fires and the environment. Namely, the relationship between biomass burning and ozone is described, starting with a brief description of the chemical reactions involved and illustrative measurements and interpretation. Second, because of the need to observe biomass burning and its consequences globally, a summary of remote sensing approaches to the study of fires and trace gases is given. Examples in this Chapter are restricted to tropical burning for matters of brevity and because most burning activity globally is within this zone.

    Pyrogenic plants dominate many fire-prone ecosystems. Their prevalence suggests some advantage to their enhanced flammability, but researchers have had difficulty tying pyrogenicity to individual-level advantages. Based on our review, we propose that enhanced flammability in fire-prone ecosystems should protect the belowground organs and nearby propagules of certain individual plants during fires. We base this hypothesis on five points: (1) organs and propagules by which many fire-adapted plants survive fires are vulnerable to elevated soil temperatures during fires; (2) the degree to which burning plant fuels heat the soil depends mainly on residence times of fires and on fuel location relative to the soil; (3) fires and fire effects are locally heterogeneous, meaning that individual plants can affect local soil heating via their fuels; (4) how a plant burns can thus affect its fitness; and (5) in many cases, natural selection in fire-prone habitats should therefore favor plants that burn rapidly and retain fuels off the ground. We predict an advantage of enhanced flammability for plants whose fuels influence local fire characteristics and whose regenerative tissues or propagules are affected by local variation in fires. Our "pyrogenicity as protection" hypothesis has the potential to apply to a range of life histories. We discuss implications for ecological and evolutionary theory and suggest considerations for testing the hypothesis.

    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.

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

    Assault by burning in Dhaka, Bangladesh, occurs in a variety of forms, resulting from various causes and motives. A total of 311 cases of intentional burns from the Burn Unit of Dhaka Medical College Hospital from April 2004 to May 2011 (6 years) were studied by retrospective and prospective observational review. The majority of victims (68%) were female. Concentrated sulphuric acid was the most commonly used chemical for attack. Disfigurement was the principal complication (mortality, 4%). Dowry-related issues, divorce and other marital quarrels were frequent backgrounds for assault by burning. Kerosene oil was used to ignite 78 girls or young women, most often related to conflicts over dowry (mortality 97%). A total of 102 victims (32%) in all burn groups were attacked because of dowry-related issues. Intentional contact burns were often inflicted on domestic servants. Although physical morbidity and mortality were not reported in contact and other types of burns, psychological disturbances were reported in all victims. A few victims had been assaulted prior to receiving burns, and fractures and deformities were also present on examination at the time of presentation for burn treatment. Ophthalmic injury, with frequent visual impairment, was very common in cases of chemical attack. Legal and social support for victims and their families are frequently inadequate to compensate for losses. Clearly, more attention in our community should be focussed on the prevention of burn assaults, adequate compensation and medical care for victims, as well as speedy retribution for perpetrators.

    Despite significant advances in burn surgery and critical care, severe burn trauma defined as injuries covering more than 25% of the total body surface area, is still associated with high mortality and morbidity. Burn trauma is a whole body injury where peripheral dermal injury rapidly results in systemic inflammation and inflammatory core organ damage. The severe disturbance of internal homeostasis involves all vital organ systems and obligates early referral to specialized burn centers. Treatment of severely burned patients is a multifaceted challenge directed by pathophysiologic events which progress from local skin destruction, disruption of physicochemical and microvascular barriers to breakdown of peripheral and central circulation, organ failure and ultimately death. While early intensive care focuses on maintenance of tissue oxygenation and perfusion, surgical treatment deals with management of the burn wounds as a source of inflammation and infection. Here wound debridement and coverage is essential to abrogate systemic effects of inflammation and limit pathogen invasion. While control of early burn stages minimizes mortality due to burn shock, subsequent burn sepsis continues to be a formidable challenge for physicians and the main cause of burn mortality.

    Seventy-nine persons who had sustained automobile engine carburetor- and radiator-related burns were admitted to Grady Memorial Hospital Burn Unit between June 1, 1984 and September 30, 1990. Forty patients with carburetor-priming flame burns had a mean age of 31.5 years, a mean burn size of 13.4% total body surface area, and a mean length of stay of 13.8 days. There were 37 male patients. Four patients had an inhalation injury. Twenty-two surgical procedures were performed on 13 patients. One patient was an innocent bystander, and one patient died. The clothing of 16 patients had ignited, which resulted in larger, deeper burns and in one death. Burns predominantly involved the right sides of the face, head, and torso; the right upper extremity; and the right hand. Thirty-nine patients had scald burns that were associated with uncapping a radiator. These patients had a mean age of 29.6 years, a mean burn size of 8.9% total body surface area, and a mean length of stay of 6.4 days. There were 36 male patients and three innocent bystanders. One autografting procedure was performed, and there were no deaths in this group of patients. The burn-prone person is the young adult male. The circumstances that result in such dangerous behavior are predictable, and resultant burn injuries are preventable.

    According to the World Health Organization (WHO) burns are a huge global health problem resulting in death and devastation to those who survive large burns as they are faced with significant functional limitations that prevent purposeful and productive living. Members of the International Society for Burn Injuries (ISBI) Rehabilitation Committee conducted a needs assessment survey in order to characterize how burn rehabilitation is implemented worldwide and how the international burn rehabilitation community can help improve burn rehabilitation in identified geographic locations which need assistance in rehabilitating burn survivors successfully. The results of this survey indicated that poor and in some cases resource limited environments (RLEs) around the world seem to lack the financial, educational and material resources to conduct burn rehabilitation successfully. It appears that there are vast discrepancies in the areas of education, training and capacity to conduct research to improve the care of burn survivors as evidenced by the variation in responses between the RLEs and developed countries around the globe. In some cases, the problem is not knowledge, skill and ability to practice burn rehabilitation, but rather having the resources to do so due to financial difficulties. PMID:27161089

    This study compares employment rates and barriers to return to work in subjects burned at work with those burned outside of work. Further, this study examines the influence of electrical etiology on return to work outcomes. The electronic records of burn survivors treated at a Regional Burn Center outpatient clinic from 2001 to 2007 were retrospectively reviewed. Inclusion criteria included employment at the time of burn injury and age of 18 years or older. Demographic and medical data were collected. Documentation of barriers to return to work was reviewed and classified into eight categories. Return to employment was grouped into four time intervals: 0 to 3, 3 to 6, 6 to 12, and greater than 12 months after injury. Logistic regression analysis was used to determine predictors of unemployment at greater than 1 year for subjects burned at work, outside of work, and those burned at work without electric injury. The authors identified 197 patients for inclusion in the study. Their age was 37 ± 0.8 years (mean ± SEM), and TBSA burned was 16 ± 1%. Fifty percent of subjects were burned at work. Electric etiology was seen only in those burned at work (n = 24). Forty-four percent (n = 43) of subjects injured at work remained unemployed at 1 year compared with 22% (n = 22) of subjects injured outside of work. The most frequent employment barriers included pain (72%), neurologic problems (62%), and psychiatric problems (53%) for those burned at work; and pain (63%), neurologic problems (59%), and impaired mobility (54%) for those burned outside of work. Significant predictors of unemployment at greater than 12 months included burn at work, pain, impaired mobility, other medical problems, and inpatient rehabilitation (P < .05). When the electrical injury subjects are removed from the analysis, significant predictors of unemployment at 12 months include burn at work, pain, inpatient rehabilitation, and length of stay (P < .05).

  16. Carbon Monoxide from Biomass Burning

    2002-01-01

    This pair of images shows levels of carbon monoxide at the atmospheric pressure level of 700 millibars (roughly 12,000 feet in altitude) over the continent of South America, as observed by the Measurements Of Pollution In The Troposphere (MOPITT) sensor flying aboard NASA's Terra spacecraft. Data for producing the image on the left were acquired on March 3, 2000, and for the image on the right on September 7, 2000. Blue pixels show low values, yellows show intermediate values, and the red to pink and then white pixels are progressively higher values. In the lefthand image (March 3), notice the fairly low levels of carbon monoxide over the entire continent. The slightly higher equatorial values are the result of burning emissions in sub-Saharan Africa that are convected at the Intertropical Convergence Zone (ITCZ) and spread by the trade winds. Also, notice the effect of the elevated surface topography across the Andes Mountains running north to south along the western coastline. (In this region, white pixels show no data.) In the righthand image (September 7), a large carbon monoxide plume is seen over Brazil, produced primarily by biomass burning across Amazonia and lofted into the atmosphere by strong cloud convection. The generally higher carbon monoxide levels as compared to March are both the result of South American fire emissions and the transport of carbon monoxide across the Atlantic Ocean from widespread biomass burning over Southern Africa. These images were produced using MOPITT data, which are currently being validated. These data were assimilated into an atmospheric chemical transport model using wind vectors provided by the National Center for Environmental Prediction (NCEP). Although there is good confidence in the relative seasonal values and geographic variation measured by MOPITT, that team anticipates their level of confidence will improve further with ongoing intensive validation campaigns and comparisons with in situ and ground

    This paper studies the significance of pyrogenic (e.g., biomass burning) emissions in the production of tropospheric ozone in the tropics associated with the forest and savanna fires in the African, South American, and Indonesian regions. Using aerosol index (Al) and tropospheric column ozone (TCO) time series from 1979 to 2000 derived from the Nimbus-7 and Earth Probe TOMS measurements, our study shows significant differences in the seasonal and spatial characteristics of pyrogenic emissions north and south of the equator in the African region and Brazil in South America. In general, they are not related to the seasonal and spatial characteristics of tropospheric ozone in these regions. In the Indonesian region, the most significant increase in TCO occurred during September and October 1997, following large-scale forest and savanna fires associated with the El Nino-induced dry season. However, the increase in TCO extended over most of the western Pacific well outside the burning region and was accompanied by a decrease in the eastern Pacific resembling a west-to-east dipole about the date-line. The net increase in TCO integrated over the tropical region between 15 deg N and 15 deg S was about 6-8 Tg (1 Tg = 10(exp 12) gm) over the mean climatological value of about 72 Tg. This increase is well within the range of interannual variability of TCO in the tropical region and does not necessarily suggest a photochemical source related to biomass burning. The interannual variability in TCO appears to be out of phase with the interannual variability of stratospheric column ozone (SCO). These variabilities seem to be manifestations of solar cycle and quasibiennial oscillations.

    The impact of burn size on mortality is well known, but the association of burn size with the trajectories of long-term functional outcomes remains poorly studied. This prospective multi-center study included burned adults ages 19 to 30 years who completed the Young Adult Burn Outcome Questionnaire at initial baseline contact, 2 weeks, and at 6 and 12 months after initial questionnaire administration. Non-burned adults of comparable ages also completed the questionnaire as a reference group. The association between functional recovery and TBSA burned was analyzed longitudinally using generalized linear models with the generalized estimation equation technique. Functional status was characterized in 15 domains: physical function, fine motor function, pain, itch, social function limited by physical function, perceived appearance, social function limited by appearance, sexual function, emotion, family function, family concern, satisfaction with symptom relief, satisfaction with role, work reintegration, and religion. Scores were standardized to a mean of 50 and a SD of 10 based on non-burned controls. There were 153 burned and 112 non-burned subjects with a total of 620 questionnaires. TBSA burned was 11 ± 14% (mean ± SD); 31% had face involvement and 57% had hand involvement. The lag time from burn injury to questionnaire administration was on average 7 ± 7.7 months, with a maximum of 36 months. Lower recovery levels were associated with increasing burn size for physical function, pain, itch, work reintegration, emotion, satisfaction with symptom relief, satisfaction with role, family function, and family concern (P value ranged from .04-<.0001). No significant differences in recovery levels were found with increasing burn size for fine motor function, social function limited by physical function, sexual function, and religion; these areas tracked toward the age-matched non-burned group regardless of burn size.

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

  20. The consequences of global biomass burning

    NASA Technical Reports Server (NTRS)

    Levine, Joel S.

    1991-01-01

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

    Actinide burning in CANDU reactors has been studied as a method of reducing the actinide content of spent nuclear fuel from light water reactors, and thereby decreasing the associated long term decay heat load. In this work simulations were performed of actinides mixed with natural uranium to form a mixed oxide (MOX) fuel, and also mixed with silicon carbide to form an inert matrix (IMF) fuel. Both of these fuels were taken to a higher burnup than has previously been studied. The total transuranic element destruction calculated was 40% for the MOX fuel and 71% for the IMF. (authors)

    Hydrofluoric acid (HF) is a strong inorganic acid commonly used in many domestic and industrial settings. It is one of the most common chemical burns encountered in a burn center and frequently engenders controversy in its management. We report our 15 year experience with management of HF burns. We reviewed our experience from 1990 to 2005 for patients admitted with HF burns. Primary treatment was with calcium gluconate gel. Arterial infusion of calcium and fingernail removal were reserved for unrelenting symptoms. There were 7944 acute burn admissions to our center during this study period, 204 of which were chemical burns. HF burns comprised 17% of these chemical burn admissions (35 patients). All were men, with a mean burn size of 2.1 +/- 1.5% (range, 1-6%) and hospital stay of 1.6 +/- 0.7 days (range, 0-3 days). The most common seasonal time of injury was in the summer. Twelve patients (34%) were admitted to the intensive care unit for a total of 14 intensive care unit days, primarily for arterial infusions. Ventilator support was not required in any patient. No electrolyte abnormalities occurred. All burns were either partial thickness or small full thickness with no operative intervention required and no deaths. The upper extremity was most commonly involved (29 patients, 83%). The most common cause was air conditioner cleaner (8 patients, 23%). HF is a common cause of chemical burns. Although hospital admission is usually required for vigorous treatment and pain control, burn size is usually small and does not cause electrolyte abnormalities, significant morbidity, or death.

    Summary Burn care providers are usually challenged by multiple complications during the management of acute burns. One of the most common complications worldwide is renal failure. This article reviews the various aspects of renal failure management in burn patients. Two different types of renal failures develop in these patients. The different aetiological factors, incidence, suspected prognosis, ways of diagnosing, as well as prevention methods, and the most accepted treatment modalities are all discussed. A good understanding and an effective assessment of the problem help to reduce both morbidity and mortality in burn management. PMID:23966893

    Acid burn injuries in Bangladesh primarily occur as a result of intentional attacks although there are incidences of accidental acid burns in industry, on the street, and at home. A total of 126 patients with acid burns, 95 from attacks and 31 from accidents, were studied from July 2004 to December 2012. A diagnosis of acid burn was made from history, physical examination and in some cases from chemical analysis of the patients' clothing. Alkali burns were excluded from the study. In the burn unit of Dhaka Medical College Hospital, we applied a slightly different protocol for management of acid burns, beginning with plain water irrigation of the wound, which effectively reduced burn depth and the requirement of surgical treatment. Application of hydrocolloid dressing for 48-72 h helped with the assessment of depth and the course of treatment. Early excision and grafting gives good results but resultant acid trickling creates a marble cake-like appearance of the wound separated by the vital skin. Excision with a scalpel and direct stitching of the wounds are often a good option. Observation of patients on follow-up revealed that wounds showed a tendency for hypertrophy. Application of pressure garments and other scar treatments were given in all cases unless the burn was highly superficial.

    2010-01-01

    Recently, much attention has been placed on quality of care metrics and patient safety. Groups such as the University Health-System Consortium (UHC) collect and review patient safety data, monitor healthcare facilities, and often report data using mortality and complication rates as outcomes. The purpose of this study was to analyze the UHC database to determine if it differentiates quality of care across burn centers. We reviewed UHC clinical database (CDB) fields and available data from 2006 to 2008 for the burn product line. Based on the September 2008 American Burn Association (ABA) list of verified burn centers, we categorized centers as American Burn Association-verified burn centers, self-identified burn centers, and other centers that are not burn units but admit some burn patients. We compared total burn admissions, risk pool, complication rates, and mortality rates. Overall mortality was compared between the UHC and National Burn Repository. The UHC CDB provides fields for number of admissions, % intensive care unit admission, risk pool, length of stay, complication profiles, and mortality index. The overall numbers of burn patients in the database for the study period included 17,740 patients admitted to verified burn centers (mean 631 admissions/burn center/yr or per 2 years), 10,834 for self-identified burn centers (mean 437 admissions/burn center/yr or per 2 years), and 1,487 for other centers (mean 11.5 admissions/burn center/yr or per 2 years). Reported complication rates for verified burn centers (21.6%), self-identified burn centers (21.3%), and others (20%) were similar. Mortality rates were highest for self-identified burn centers (3.06%), less for verified centers (2.88%), and lowest for other centers (0.74%). However, these outcomes data may be misleading, because the risk pool criteria do not include burn-specific risk factors, and the inability to adjust for injury severity prevents rigorous comparison across centers.

    Computer simulation was used in the development of an inward-burning, radial matrix gas burner and heat pipe heat exchanger. The burner and exchanger can be used to heat a Stirling engine on cloudy days when a solar dish, the normal source of heat, cannot be used. Geometrical requirements of the application forced the use of the inward burning approach, which presents difficulty in achieving a good flow distribution and air/fuel mixing. The present invention solved the problem by providing a plenum with just the right properties, which include good flow distribution and good air/fuel mixing with minimum residence time. CFD simulations were also used to help design the primary heat exchanger needed for this application which includes a plurality of pins emanating from the heat pipe. The system uses multiple inlet ports, an extended distance from the fuel inlet to the burner matrix, flow divider vanes, and a ring-shaped, porous grid to obtain a high-temperature uniform-heat radial burner. Ideal applications include dish/Stirling engines, steam reforming of hydrocarbons, glass working, and any process requiring high temperature heating of the outside surface of a cylindrical surface.

  16. A radical way to burn

    SciTech Connect

    Ashley, S.

    1996-08-01

    By manipulating chamber geometries as well as engine cycle pressures and timing, engineers are exploiting a long-obscure technology known as activated radical combustion. Piston-driven internal combustion engines generally come in two varieties: compression-ignited diesels and spark-ignited gasoline power plants. There, is however, a third way to initiate burning of the fuel-air mixture. The technique--variously called radical ignition (RI), activated radical (AR) combustion, Toyota-Soken combustion, and active thermo-atmosphere combustion--is not exactly new, but only recently have engineers begun to exploit the process in practical power plants. These new units include a lightweight two-stroke racing-motorcycle engine, truck diesels with reduced soot output, and lean-burn spark-ignited car engines. This long-obscure combustion process is based on a range of specialized chemical kinetic and physical acoustic techniques developed over decades. Engineers manipulate fundamental combustion parameter such as chamber geometries, valving and porting configurations, and engine cycle pressures and timing to foster the formation of certain highly reactive chemical species that lower the fuel-air mixture`s flash point so that even modest compression make sit self-ignite. These chemical initiators are then retained into the next cycle to start combustion, allowing the engineer to run stably with no spark.

    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.

    Four major vegetation types are shown to be the dominant ecosystems over Kayamba County in the Congo (DRC). Covering about 76.6% of the County total area, savanna is the largest land cover type, and the marshlands (grass formations over waterlogged soils) the second (12.9% of the area). This amounts to 89.5% of the County lands being covered with herbaceous vegetations, compared to a very weak proportion of forests cover (10.5%). Open water bodies are rare, covering only 1.1 km2 (0.04%) of the County territory. They consist mostly of small ponds in the vast marshlands along the main rivers. Kayamba is thus shown to be a savanna area, with large expanse of wetlands and scattered patches of various types of tropical rainforests (natural or man-made forests, and sparse woodlands). Rain fed agriculture (slash and burn in the forests, or shifting cultivation in the savanna) is shown to be the main life-sustaining human activity among the Luba of Kayamba County. Its full dependence on the natural elements (especially the rainfall) makes it easily affected by any variability in the climatic regimes. Hunting, fishing and gathering provide a supplement to the daily food intake. This lifestyle compares to that of other tropical rainforest dwellers (e.g. the Kayapo Indian in Brazil or the Karen in Thailand). A strong village dynamics (permanent relocations in the North and the Center, new villages built at important crossways, or splitting followed by relocation along main arteries in the South), more likely in response to the need for a new economy-oriented way of life in the County is also observed, pointing to the need for more investigation in relation with the possible development of this area. Biomass burning in Kayamba is either planned (bushfire hunting) or accidental (uncontrolled fires from field debris burning), occurring exclusively during the peak of the dry season (June-July). The seasonal bushfires regime is analyzed and discussed. It is shown that of the

    The aim of this study is to quantify the changes in incidence, severity, and mortality in burn injuries in the state of Maine over the past 50 years from both prevention and treatment perspectives. The authors analyzed the data from multiple sources, including the U.S. Census, death certificates, hospital discharge abstracts, and institutional burn registries in Maine and Boston. The average annual number of burn-related deaths decreased from 53 in 1960-1964 to 14 in 2004-2008. The Maine age-adjusted rate of burn deaths was 8.6% above the national rate in 1960 and 1.4% below it in 2006. The annual number of burn patients admitted to Maine hospitals declined by 65% from 1978 to 2009. Since 1999, 12% of hospitalized patients in Maine were treated in an American Burn Association-certified burn center in Boston. Mortality for Maine burn patients, including those treated at Boston hospitals, is directly related to age and burn severity and similar to stratified mortality in the National Burn Repository. Incidence, severity, and mortality of burn injuries in Maine have decreased dramatically over the past 5 decades. Prevention programs, legislation, and a regionalized system of burn care have all likely contributed to bringing Maine's morbidity and mortality rate below the national average. PMID:22002206

    Throughout most of history, serious burns occupying a large percentage of body surface area were an almost certain death sentence because of subsequent infection. A number of factors such as disruption of the skin barrier, ready availability of bacterial nutrients in the burn milieu, destruction of the vascular supply to the burned skin, and systemic disturbances lead to immunosuppression combined together to make burns particularly susceptible to infection. In the 20th century the introduction of antibiotic and antifungal drugs, the use of topical antimicrobials that could be applied to burns, and widespread adoption of early excision and grafting all helped to dramatically increase survival. However the relentless increase in microbial resistance to antibiotics and other antimicrobials has led to a renewed search for alternative approaches to prevent and combat burn infections. This review will cover patented strategies that have been issued or filed with regard to new topical agents, preparations, and methods of combating burn infections. Animal models that are used in preclinical studies are discussed. Various silver preparations (nanocrystalline and slow release) are the mainstay of many approaches but antimicrobial peptides, topical photodynamic therapy, chitosan preparations, new iodine delivery formulations, phage therapy and natural products such as honey and essential oils have all been tested. This active area of research will continue to provide new topical antimicrobials for burns that will battle against growing multi-drug resistance. PMID:20429870

    2005-04-01

    Extensive thermal injuries in horses can be difficult to manage. The large surface of the burn dramatically increases the potential for loss of fluids,electrolytes, and calories. Burns are classified by the depth of injury: first-degree burns involve only the most superficial layers of the epidermis;second-degree burns involve the entire epidermis and can be superficial or deep; third-degree burns are characterized by loss of the epidermal and dermal components; and fourth-degree burns involve all the skin and underlying muscle, bone, and ligaments. Burns cause local and systemic effects. Routine use of systemic antibiotics is not recommended in burn patients. Topical medications should be water based, be easily applied and removed, not interfere with wound healing, and be readily excreted or metabolized. Weight loss of 10% to 15% during the course of illness is indicative of inadequate nutritional intake. Gradually increasing the grain,adding fat in the form of vegetable oil, and offering free-choice alfalfa hay increase caloric intake.

    2015-01-01

    Introduction: In Konya, Turkey, the community celebrates the traditional ceremony of Shivlilik, which occurs on the first day of the seventh month in the lunar-based Hijri calendar. In the evening, people light bonfires of tires in the streets, and children and young people attempt to jump over the flames. Flame burns regularly occur due to falling. Attention should be given to preventing injuries such as these that are caused by social and regional customs. Methods: This retrospective study was carried out using data from the Konya Education and Research Hospital Burn Unit. Patients admitted to our hospital between June, 2009, and May, 2012, was evaluated. Results: Eleven patients were admitted to hospital with flame burns caused by jumping over fires on the days when the traditional Shivlilik ceremony was celebrated. The clinical data evaluated included the patient’s age and sex, the depth of the burn injury, the total burned surface area (TBSA), and the distribution of the burn areas. Conclusions: Serious flame burns occur because of the traditional Shivlilik ceremony. We must promote some changes in this ceremony in order to prevent these burns. PMID:26550532

    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. Interestingly, we could not find a higher incidence of infection or sepsis in elderly, 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.

  20. Cooling of burns: Mechanisms and models.

    Wright, E H; Harris, A L; Furniss, D

    2015-08-01

    The role of cooling in the acute management of burns is widely accepted in clinical practice, and is a cornerstone of basic first aid in burns. This has been underlined in a number of animal models. The mechanism by which it delivers its benefit is poorly understood, but there is a reduction in burns progression over the first 48 h, reduced healing time, and some subjective improvements in scarring when cooling is administered after burning. Intradermal temperature normalises within a matter of seconds to a few minutes, yet the benefits of even delayed cooling persist, implying it is not simply the removal of thermal energy from the damaged tissues. Animal models have used oedema formation, preservation of dermal perfusion, healing time and hair retention as indicators of burns severity, and have shown cooling to improve these indices, but pharmacological or immunological blockade of humoural and cellular mediators of inflammation did not reproduce the benefit of cooling. More recently, some studies of tissue from human and animal burns have shown consistent, reproducible, temporal changes in gene expression in burned tissues. Here, we review the experimental evidence of the role and mechanism of cooling in burns management, and suggest future research directions that may eventually lead to improved treatment outcomes.

    Objectives: Increasingly (but not exclusively), terrorist activity and the use of explosive devices have enjoyed the focus of the global media. This paper aims to bring a range of issues to attention, to highlight how burn injuries are sustained in such incidents and why burn injuries (and thus burn disasters) are so complicated to manage. Materials and Methods: The author's experience with burn injury caused during explosions and his involvement in burn disaster situations has been summarized to form the basis of the article. This has been expanded upon with discussion points which provide a strategy for planning for such events and by a broad sample of the literature. Results: Several strategies are suggested to facilitate planning for burn disasters and to illustrate to those not directly involved why forward planning is pivotal to success when these incidents occur. Conclusions: Disasters generating large numbers of burn-injured are relatively frequent. Explosive devices are widespread in their use both in military and increasingly in civilian fields. Encompassing a large range of aetiologies, geographical sites, populations, and resources; burn disaster management is difficult and planning essential. PMID:19834533

    Biomass burning covers open fires (forest and grassland fires, crop residue burning in fields, etc.) and biofuel combustion (crop residues and wood, etc., used as fuel). As a large agricultural country, China may produce large quantities of mercury emissions from biomass burning. A new mercury emission inventory in China is needed because previous studies reflected outdated biomass burning with coarse resolution. Moreover, these studies often adopted the emission factors (mass of emitted species per mass of biomass burned) measured in North America. In this study, the mercury emissions from biomass burning in China (excluding small islands in the South China Sea) were estimated, using recently measured mercury concentrations in various biomes in China as emission factors. Emissions from crop residues and fuelwood were estimated based on annual reports distributed by provincial government. Emissions from forest and grassland fires were calculated by combining moderate resolution imaging spectroradiometer (MODIS) burned area product with combustion efficiency (ratio of fuel consumption to total available fuels) considering fuel moisture. The average annual emission from biomass burning was 27 (range from 15.1 to 39.9) Mg/year. This inventory has high spatial resolution (1 km) and covers a long period (2000-2007), making it useful for air quality modeling.

    Chlorhexidine is an antiseptic and disinfectant commonly used for surgical site preparation and cleansing. It is active against a broad spectrum of bacteria, viruses, mycobacteria, and fungi. We report 3 cases of patients with superficial partial thickness burns immediately following shoulder arthroscopic surgery with the use of a Chloraprep 26 mL applicator (2% chlorhexidine gluconate and 70% isopropyl alcohol; CareFusion, Leawood, Kansas). All 3 patients reported pain as the anesthetic waned at a localized area on the anterior arm near the axilla. Erythema and blistering were noticeable. These areas were immediately treated with irrigation and local application of ice, and subsequently with topical triple-antibiotic ointment. All 3 cases were resolved within 3 months of surgery, but noticeable scars remained. We believe a combination of chlorhexidine skin preparation, local swelling inherent to shoulder arthroscopy, and traction contributed to these postoperative complications.

    NASA's Mars Exploration Rover Opportunity captured this view from the base of 'Burns Cliff' during the rover's 280th martian day (Nov. 6, 2004). This cliff in the inner wall of 'Endurance Crater' displays multiple layers of bedrock for the rover to examine with its panoramic camera and miniature thermal emission spectrometer. The rover team has decided that the farthest Opportunity can safely advance along the base of the cliff is close to the squarish white rock near the center of this image. After examining the site for a few days from that position, the the rover will turn around and head out of the crater. The view is a mosaic of frames taken by Opportunity's navigation camera. The rover was on ground with a slope of about 30 degrees when the pictures were taken, and the view is presented here in a way that corrects for that tilt of the camera.

  9. Modern trends in fluid therapy for burns.

    PubMed

    Tricklebank, Stephen

    2009-09-01

    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.

    Rhabdomyolysis due to flame burns is not well described. A case of fatal rhabdomyolysis in an epileptic patient who sustained 65 per cent body surface area, very deep, flame burns is described. It appears as if the sustained muscle compression from the restrictive, circumferential eschar was the major factor in the aetiology of the rhabdomyolysis. Despite aggressive fluid management, the patient died of acute renal failure and adult respiratory distress syndrome. We have subsequently identified three other cases of pigmenturia occurring following burns. It would seem as if rhabdomyolysis following extensive full thickness burns may be more common than previously suggested. Fluid requirements are in excess of those proposed by traditional protocols. Rhabdomyolysis in flame burn patients indicates a poor prognosis. PMID:9426917

    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.

    For more than a decade NIST conducted research to understand, measure and predict the important features of burning oil on water. Results of that research have been included in nationally recognized guidelines for approval of intentional burning. NIST measurements and predictions have played a major role in establishing in situ burning as a primary oil spill response method. Data are given for pool fire burning rates, smoke yield, smoke particulate size distribution, smoke aging, and polycyclic aromatic hydrocarbon content of the smoke for crude and fuel oil fires with effective diameters up to 17.2 m. New user-friendly software, ALOFT, was developed to quantify the large-scale features and trajectory of wind blown smoke plumes in the atmosphere and estimate the ground level smoke particulate concentrations. Predictions using the model were tested successfully against data from large-scale tests. ALOFT software is being used by oil spill response teams to help assess the potential impact of intentional burning.

  13. Interaction of Burning Metal Particles

    Dreizin, Edward L.

    1997-01-01

    Multiple particle/droplet flames are ubiquitous in practical combustion systems, and thus the flame interaction processes are of great practical importance. This explains the strong current interest in interactive combustion phenomena. This research is aimed at the investigation of combustion parameters of microgravity model aerosols: relatively large uniform metal particles aerosolized in microgravity environment. An experiment consisting of creation and ignition of a metal multiparticle system in microgravity and high-speed video-recording of the combustion events will produce visual records of the development of individual particle flames, their interactions and the particle motion they induce simultaneously with the observation of the entire aerosol combustion process. Frame by frame analysis of the video-images taken using a high-speed movie camera will allow one to determine particle brightness temperatures and the decrease in particle diameter during combustion. Analysis of the experimental results and comparison with the results of single metal particle combustion experiments, conducted under similar microgravity conditions in the framework of a parallel program, will establish the relationship between single and multiple particle burning rates and combustion temperatures, concentrations at which the flame substructure forms rather than individual particle flames, efficiency of radiative heat transfer in metal aerosol combustion, what is the role of electrostatic forces in structuring the flame and the effect of that structure on the flame propagation rate. Although some details of fine particle aerosol clouds, such as the kinetics limited burning rate, radiative heat transfer in a system with a high specific surface, particle induced turbulence, etc., will probably not be very well simulated in the planned experiments, they are relatively well understood and can be accounted for using an adequate individual particle combustion model.

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.

    2002-01-01

    It has been estimated that 2 million people per year have burns requiring medical attention in the United States. The available and expert clinicians in dedicated burn centers around the country have cared successfully for these patients and given them a second chance at a functional life. It still behooves current-day plastic surgeons to be knowledgeable and adept in their care, not only because they may be called upon at times to manage some of the smaller acute burns, but also because many of the general principles of burn reconstruction and wound management are relevant to other areas of general plastic surgery. Acute burns should be dealt with like any other major trauma with the ABCs of aggressive resuscitation and airway management. Like any other wound, debridement and nutrition are important (i.e., early escharectomy of the burn wound and enteral nutrition during the hypermetabolic state). Early coverage of the open wound is essential to limit bacterial colonization and prevent infection and to reduce fluid and electrolyte and heat loss. If autografts are not available immediately, temporary coverage with one of the above-mentioned barrier materials should be used. Still, autografts, when available, should be the burn surgeon's first choice. Donor sites may be reharvested to provide more autograft than was anticipated with large-percentage TBSA burns. Physicians should keep in mind the advantages (and disadvantages) of using the scalp and back. As far as research and technological advances in the area of plastic surgery, burn surgery may be the most progressive, with the evolution of biologic tissue-engineered skin substitutes and the research of growth factors in healing. Further improvements in tissue engineering and technology should result in even more effective skin substitutes and hence better functional and aesthetic outcomes with economic efficiency in large burns.

    Deep burns lead to scarring and contractures for which there is little or no published data on treatment costs. The purpose of this study was to fill this gap by analysing treatment costs for burn sequelae. To do this, German-DRG for in-patient treatment was collected from the Burn Centre Lower Saxony. DRG-related T95.-coding served as a tool for burn-associated sequelae. Data on scar occurrence, plastic-reconstructive surgery and sick leave were collected by a questionnaire. The findings showed that 44.6% patients reported post-burn scarring and 31% needed surgical intervention. The expected risk for readmission was significantly higher (p=0.0002) with scars compared to without. Significantly higher costs for pressure garments were noted for scarred patients (p=0.04). No differences were found for ointments, silicone dressings or pain medication. Treatment costs for patients with scars were 5.6 times higher compared with no scar assessed by G-DRG. No differences were stated subsuming multiple readmissions for post-burn treatment per individual. Significantly higher costs (p=0.03) were noted for patients with burn sequelae other than scars with regard to individual readmissions. It has been revealed that treatment of scars causes higher costs than for other burn sequelae because of multiple surgical interventions. To reduce post-burn scarring and costs, specialized burn centres provide optimal and state-of-the-art treatment. As well as this, more emphasis should be laid on promoting research for the development of novel anti-scarring therapies. PMID:27279810

    Understanding burns means knowing what is necessary for the successful treatment of burns. Nobody in science, economics, or quality control can comprehend this issue's complexity without thorough documentation of the work involved. BurnCase 3D is a non-profit research project whose aim, achieved through software of the same name, is a thorough and accurate burn-treatment documentation schema, facilitated by three-dimensional digital models tracked over time. Adapting these models on the basis of gender, height, weight, and body shape avoids systemic errors. Superimposing photos of the burned areas on the model prevents individual error and can be combined with methods of burn-depth evaluation. The program includes automatic encoding of diagnostic and therapeutic procedures. Model resolution is 1cm(2) and finer, so that even small scars' locations and extents can be documented, thus enabling registration of long-term results. The program's status as a multilingual data-collection tool brings together multiple international efforts in data collection, and makes it suitable for e-medicine and disaster relief. In its basic form, it provides essential functions in burn documentation, photo documentation, and reporting. The four-dimensional database allows registration of interactions over time and can demonstrate the influence of location, timing, and intervention on outcome.

    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.

    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.

    In preventing burns, it is essential to know how they occur and which population groups, environments and heating appliances can be targeted for prevention work. The aim of this study was to determine the epidemiological characteristics of burns leading to hospitalisation in the northwest of Iran with a focus on the pre-event phase of injury. Between 2007 and 2008, 237 burn victims hospitalised in Ardabil provincial burn centre were enrolled into a descriptive study. A questionnaire was filled in during hospital stay for all patients, with a focus on obtaining information necessary for prevention purposes. Males constituted 56% of victims. Mean age was 22 years. The most severe burns occurred between the ages of 18 and 32 years, and were mainly flame related. Both in case of flame and non-flame burns, women suffered more severe burns and mortality than men. However, with respect to non-flame burns of which most were scalds, the majority of the severe cases involved children under the age of 5 years. More than 80% of burns occurred at home. The kitchen was the main place of injury in 47% of cases, followed by living rooms in 28%. Nearly 45% of burns were scalds and 47% were flame burns. The main container was the samovar in 37%, followed by kettles in 32% and pots in 22%. The overturning of a container was the major mechanism of contact with hot liquids in 86%. Bumping into a container was the main scenario of a scald injury, constituting nearly 70% of the cases. The difference between flame and non-flame burns in the distribution of burns in extremities was not statistically significant, but head and neck burns were 3.7 times more likely to be caused by flame. The two most important injury patterns, more common among women, were getting burned while using a camping gas stove or while refilling the chamber of kerosene-burning appliances without first extinguishing them. Domestic burns among children and young women are a priority in injury-prevention programmes

    Modern burn care techniques have reduced the risk of infection of the acute burn wound, resulting in more rapid healing and a lower incidence of graft loss. Secondary breakdown may still occur. The loss of epithelium in association with multifocal superficial abscesses and ulceration has been termed burns impetigo. This may result in considerable morbidity and require prolonged treatment. The events preceding development, the impact on the patient, and the ideal treatment appear unclear and poorly reported. In 5 years, between 2006 and 2011, 406 pediatric burns were treated with skin grafts, with 7% developing burns impetigo. Time to resolution ranged from 5 to 241 days: the mean time to complete healing was greatest with conservative management (96 days), followed by antibacterial dressings (37 days), oral antibiotics (36 days), topical steroids (16 days), and oral antibiotics in combination with topical steroids (13.5 days). Burns impetigo resulted in significant morbidity, requiring multiple visits to the treatment center and prolonged symptoms. Delay in diagnosis and treatment resulted in worse outcomes. Prompt consideration of burns impetigo should occur when postgraft patients present with suggestive clinical signs and treatment with oral antibiotics plus topical steroids should be considered.

    A planned treatment program for burned hands has been developed and was used in 72 burns of the dorsum of the hands. Treatment was individualized on the basis of whether hand burns were superficial or deep. In the former, there was evidence of spontaneous reepithelialization within 14 to 21 days. In the latter, immediate or delayed excision, followed by resurfacing with autografts was done. Both groups received topical antibiotic creaming, elevation, an exercise program as soon as they were able, and splinting of the burned hand in the antideformity position. Hypertrophic scars and unacceptable epithelium were excised when they interfered with function. Initially, this program allowed us to avoid unnecessary surgical procedures in 94% of the second-degree burns of the dorsum of the hand. The third-degree burned hand needed excision and autografting in 100% of the burned hands. This treatment program has as its goals: prevention of deformity by early motion and protection of the unburned and regenerating epithelium by creaming with topical antibiotic ointment.

  9. Electrothermal ring burn from a car battery.

    Despite prevention efforts, burn injuries among auto mechanics are described in the literature. Electrothermal ring burns from car batteries occur by short-circuiting through the ring when it touches the open terminal or metal housing. This article describes a 34-year-old male auto mechanic who was holding a wrench when his gold ring touched the positive terminal of a 12-volt car battery and the wrench touched both his ring and the negative terminal. He felt instant pain and had a deep partial-thickness circumferential burn at the base of his ring finger. No other soft tissues were injured. He was initially managed conservatively, but after minimal healing at 3 weeks, he underwent a full-thickness skin graft. The graft incorporated well and healed by 4 weeks postoperatively. He had full range of motion. The cause of ring burns has been controversial, but based on reports similar to the current patient's mechanism, they are most likely electrothermal burns. Gold, a metal with high thermal conductivity, can heat up to its melting point in a matter of seconds. Many treatments have been described, including local wound care to split- and full-thickness skin grafts. Because most burns are preventable, staff should be warned and trained about the potential risks of contact burns. All jewelry should be removed, and the live battery terminal should be covered while working in the vicinity of the battery.

    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. PMID:27013315

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

    Automobile air bags have gained acceptance as an effective measure to reduce the morbidity and mortality associated with motor vehicle accidents. As more cars have become equipped with them, new problems have been encountered that are directly attributable to the deployment of the bag itself. An increasing variety of associated injuries has been reported, including minor burns. We present two automobile drivers who were involved in front-impact crashes with air bag inflation. They sustained superficial and partial-thickness burns related to the deployment. The evaluation of these cases shows mechanisms involved in burn injuries caused by the air bag system. Most of the burns are chemical and usually attributed to sodium hydroxide in the aerosol created during deployment. Also direct thermal burns from high-temperature gases or indirect injuries due to the melting of clothing, as well as friction burns from physical contact are possible. However, the inherent risks of air bag-related burns are still outweighed by the benefits of preventing potentially life-threatening injuries. PMID:11226663

    Scalp burns in the pediatric population appear relatively uncommon, with most reported cases occurring in adults secondary to electrical burns. We reviewed our experience with the management of these injuries in children. A retrospective review was conducted at our institution from March 2004 to July 2011. Scalp burns were defined as any burn crossing over the hairline into the scalp region. During the 7-year 4-month study, there were 107 scalp burns, representing 1.8% of the 6074 burns treated at our institution during that time. The cause was scald in 97, contact in 4, flame in 3, friction in 2, and chemical in 1. The majority (n = 93, 87%) appeared superficial to mid-dermal, with an average time to complete healing of 10.3 days. The remaining 14 cases (13%) were mid-dermal to full thickness, with an average time to complete healing of 50.8 days. Grafting was required in 12 cases (11%). The mean time to grafting was 4 weeks (range, 2 weeks to 2.5 months). The main complication of scalp burns was alopecia, which occurred in all grafted sites as well as in 4 patients treated conservatively. There were no other complications after grafting and no cases of graft loss. In our pediatric series, scalp burns were most commonly caused by scald injuries and were superficial to mid-dermal in depth. These generally healed rapidly but occasionally resulted in alopecia. The management of deep dermal and full-thickness scalp burns remains challenging in children, with the decision to graft often delayed.

    Summary Face burns expose patients to a higher respiratory risk, and early prophylactic intubation before they enter the burn unit might be life-saving. However, unnecessary intubation may compromise their clinical evolution. Hence, the decision to perform pre-burn centre endotracheal intubation remains a clinical challenge. A retrospective study was developed to characterize the experience of the tertiary burn unit of the Hospital da Prelada with face burn patients arriving endotracheally-intubated between January 2009 and September 2013. Specific goals included assessment of whether these intubations were clinically appropriate and if these procedures determined significant changes in clinical course and outcome. A total of 136 patients were admitted to our burn centre with facial burns. 38.2% (n=52) of them arrived endotracheally-intubated, with 75% (n=39) intubated at the scene of the burn injury and 25% (n=13) in the emergency room because of the suspicion of smoke inhalation injury. In only 23% of the cases (n=12) was the lesion confirmed by bronchoscopy. The overall mortality rate was 12.5% (n=17): 3.6% (n=3) were patients who had not been subjected to pre-burn centre intubation, and 27% (n=14) were in the group of patients arriving intubated. A face burn is a warning sign of a possible upper airway injury, and pre-burn centre prophylactic intubation might be life-saving. However, unnecessary intubation may impair clinical evolution. Therefore, it is imperative that updated practice guidelines for pre-burn centre airway management are adhered to, and that these guidelines are subject to revision in order to improve airway management in burn patients.

    The clinical utility of hypnosis for controlling pain during burn wound debridement was investigated. Thirty hospitalized burn patients and their nurses submitted visual analog scales (VAS) for pain during 2 consecutive daily wound debridements. 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

    This article discusses commonly used methods of monitoring and determining the end points of resuscitation. Each end point of resuscitation is examined as it relates to use in critically ill burn patients. Published medical literature, clinical trials, consensus trials, and expert opinion regarding end points of resuscitation were gathered and reviewed. Specific goals were a detailed examination of each method in the critical care population and how this methodology can be used in the burn patient. Although burn resuscitation is monitored and administered using the methodology as seen in medical/surgical intensive care settings, special consideration for excessive edema formation, metabolic derangements, and frequent operative interventions must be considered.

    Physical characteristics of the combustion of metal particle groups have been addressed in this research. The combustion behavior and interaction effects of multiple metal particles has been studied using a microgravity environment, which presents a unique opportunity to create an "aerosol" consisting of relatively large particles, i.e., 50-300 micrometer diameter. Combustion behavior of such an aerosol could be examined using methods adopted from well-developed single particle combustion research. The experiment included fluidizing relatively large (order of 100 micrometer diameter) uniform metal particles under microgravity and igniting such an "aerosol" using a hot wire igniter. The flame propagation and details of individual particle combustion and particle interaction have been studied using a high speed movie and video-imaging with cameras coupled with microscope lenses to resolve individual particles. Interference filters were used to separate characteristic metal and metal oxide radiation bands form the thermal black body radiation. Recorded flame images were digitized and employed to understand the processes occurring in the burning aerosol. The development of individual particle flames, merging or separation, and extinguishing as well as induced particle motion have been analyzed to identify the mechanisms governing these processes. Size distribution, morphology, and elemental compositions of combustion products were characterized and used to link the observed in this project aerosol combustion phenomena with the recently expanded mechanism of single metal particle combustion.

    The Transition From Ignition to Flame Growth Under External Radiation in 3D (TIGER- 3D) experiment, which is slated to fly aboard the International Space Station, conducted a series of highly successful tests in collaboration with the University of Hokkaido using Japan's 10-sec JAMIC drop tower. The tests were conducted to test engineering versions of advanced flight diagnostics such as an infrared camera for detailed surface temperature measurements and an infrared spectroscopic array for gas-phase species concentrations and temperatures based on detailed spectral emissions in the near infrared. Shown in the top figure is a visible light image and in the bottom figure is an infrared image at 3.8 mm obtained during the microgravity tests. The images show flames burning across cellulose samples against a slow wind of a few centimeters per second (wind is from right to left). These flow velocities are typical of spacecraft ventilation systems that provide fresh air for the astronauts. The samples are ignited across the center with a hot wire, and the flame is allowed to spread upwind and/or downwind. As these images show, the flames prefer to spread upwind, into the fresh air, which is the exact opposite of flames on Earth, which spread much faster downwind, or with the airflow, as in forest fires.

    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.

    Burn experts estimate that 20-30 per cent of injuries from mass casualty events result in serious burns, many requiring specialised care only available at burn centres. Yet, in the USA there are less then 1,850 burn beds available to provide such a level and quality of care. To address this concern, burn centres are beginning to put into practice new mass casualty triage and transport guidelines that must coordinate with local, regional and federal response plans, while still adhering to an accepted standard of care. This presentation describes how one US burn centre developed and implemented a Homeland Security Exercise and Evaluation Program (HSEEP) designed mass casualty incident (MCI) exercise focused on coordinating 'the right patient to the right facility at the right time', based upon acuity and bed availability. Discussion will enable planners to identify methodologies adaptable for incorporation into catastrophic emergency management operations within their regions.

    Cement is extensively used both in the professional construction and "do-it-yourself" industries. Despite a number of small published series during the past 80 years highlighting its potential for harm, little seems to have been done to make consumers aware of its risks of causing serious burn injuries. The authors present 10 years of a tertiary adult burn center's experience with these burns, and highlight the significance of these burns on the active, working sector of society. Both professionals and part-time enthusiasts are affected, with burns of significant depth and subsequent impairment of normal functioning. The authors propose a better education system to highlight the risks and, in time, reduce the incidence of cement burns.

    Tap water scald burns account for 7% to 17% of all childhood scald burns that require hospitalization. Often the burns are severe and disabling. Toddlers and preschool children are the most frequent victims. In 45% of the injuries, the unsupervised victim or a peer turned on the tap water; in 28% the cause was abuse. Eighty per cent of the homes tested had unsafe bathtub water temperatures of 54°C (130°F) or greater, exposing the occupants to the risk of full thickness scalds with 30 second exposure to hot water. Such burns may be prevented passively by limiting household water temperatures to less than 52°C (125°F). New water heaters could be preset at this temperature and families could be taught to turn down the temperature on existing units. PMID:9867427

    We have studied actinide burn-up in ICF reactor pellets; i.e., 14 MeV neutron fission of the very long-lived actinides that pose storage problems. A major advantage of pellet fuel region burn-up is safety: only milligrams of highly toxic and active material need to be present in the fusion chamber, whereas blanket burn-up requires the continued presence of tons of actinides in a small volume. The actinide data tables required for Monte Carlo calculations of the burn-up of /sup 241/Am and /sup 243/Am are discussed in connection with a study of the sensitivity to cross section uncertainties. More accurate and complete cross sections are required for realistic quantitative calculations.

    Olive oil is concentrated in the Mediterranean basin countries. Since the olive oil industries are incriminated for a high quantity of pollution, it has become imperative to solve this problem by developing optimized systems for the treatment of olive oil wastes. This study proposes a solution to the problem. Burned olive waste ash is evaluated for using it as clay stabilizer. In a laboratory, bentonite clay is used to improve olive waste ash. Before the laboratory, the olive waste is burned at 550°C in the high temperature oven. The burned olive waste ash was added to bentonite clay with increasing 1% by weight from 1% to 10%. The study consisted of the following tests on samples treated with burned olive waste ash: Atterberg Limits, Standard Proctor Density, and Unconfined Compressive Strength Tests. The test results show promise for this material to be used as stabilizer and to solve many of the problems associated with its accumulation. PMID:23766671

    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.

  10. Radioactivity released from burning gas lantern mantles.

    1984-04-01

    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.

    Thinner sniffing is popular among school children in Asian countries because it is readily available at low cost. Besides its toxicity to major organs, thinner inhalation is associated with various burn accidents. Four teenagers were admitted to the Burns Unit of the Prince of Wales Hospital over the period of 1996-1997. They sustained 3-25% TBSA flame burn and two of them had inhalation injuries as a result of the ignition of a cigarette during thinner sniffing. None of them had evidence of thinner intoxication as shown by blood tests. In the management of their acute burn injuries, their hidden social and family problems were explored. With the cooperation of different disciplines, early psychosocial intervention was given and their behavioral and psychological disturbances were successfully managed. PMID:9915679

    Summary A major kerosene explosion disaster occurred in oil-producing Nigeria in October 2001. One hundred and twenty-five burn patients were treated at the Lagos State University Teaching Hospital in a 25-day period of 12/10/01 to 6/11/01. All but two of the patients sustained fire/flame burns resulting from hurricane lantern and cooking stove explosions in home or enclosed environments. In a scene reminiscent of petrol bomb explosions, most burns were extensive, covering the face, chest, and abdomen. Burns were relatively deep because the clothing was usually perfused with the splashed fuel. Severity was greater in females than males, as they were more in contact with lamps and cooking stoves in the household. Almost 50% of the patients required hospitalization upwards of 3 weeks.

    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.

  16. The burning question: does burning before flooding lower methyl mercury production and bioaccumulation?

    PubMed

    2006-09-01

    Production of methyl mercury (MeHg) is elevated in new hydroelectric reservoirs because organic carbon stimulates methylation of inorganic mercury (Hg) stored in the terrestrial system. This can cause adverse health in fish and in organisms that eat fish. We expected that burning vegetation before flooding would decrease the amount of Hg and organic carbon and thereby lower MeHg production. We conducted a replicated field experiment to investigate the effects of burning vegetation and soil before flooding on MeHg production and bioaccumulation. Vegetation and soil were added to mesocosms in the following combinations: unburned vegetation and unburned soil (Fresh treatments), burned vegetation and unburned soil (Partial Burn treatments), and burned vegetation and burned soil (Complete Burn treatments). Controls had no added vegetation or soil. During combustion with propane torches, a large percentage of the total Hg (THg) and MeHg was lost from vegetation and soil. THg and MeHg concentrations were highest in the surface water of Fresh treatments, lower in Partial Burn treatments and lowest in Complete Burn treatments and controls. Differences in concentrations of MeHg in biota were consistent among treatments, but did not follow aqueous concentrations. On the final sample date, MeHg concentrations in biota of Controls and Partial Burn treatments were greater than in Complete Burn and Fresh treatments. The lack of relationship between MeHg in biota and MeHg in water may have been due to modification of the bioavailability of MeHg by dissolved organic matter as the ratios of MeHg in biota to water were inversely correlated with concentrations of dissolved organic carbon. Although burning before flooding decreased MeHg concentrations in the water, it did not lower MeHg accumulation in the lower food web.

    Summary Even if calculating the exact cost of burn treatment is a very hard task, the study of cost analysis provides financial perspective. We performed a cost analysis study in our burn centre to respond to questions about total patient treatment cost and the length of hospital stay. We reviewed all patients admitted to the Gulhane Military Medical Academy Burn Centre in Ankara, Turkey, between March 2005 and August 2008. Forty-three patients with major burns were identified on the basis of the study criteria. The data regarding total treatment cost and the length of hospital stay for each type of burn (flame, scald, electric) were collected at the end of the study. The average total body surface area burned was 36 ± 7%.. The average duration of hospital stay was 73 ± 33 days. Patients with electrical burns stayed longer in hospital than patients with other types of burn injuries. Each one per cent of burn corresponded to a mean hospital stay of two days. The overall mean total cost was $US 15,250. The mean total cost of electrical burns was the highest, with $US 22,501 ± 24,039. Even if the costs associated with burn injury are higher than some other well-known health-related problems, they have not been much studied. Reports have produced different results, but it should be kept in mind that although the results of cost analysis studies may vary they must be performed in all newly established burn centres in order to form a financial overview.

    In the last two decades, much progress has been made in the control of burn wound infection and nasocomial infections (NI) in severely burned patients. The continiually changing epidemiology is partially related to greater understanding of and improved techniques for burn patient management as well as effective hospital infection control measures. With the advent of antimicrobial chemotherapeutic agents, infection of the wound site is now not as common as, for example, urinary and blood stream infections. Universal application of early excision of burned tissues has made a substantial improvement in the control of wound-related infections in burns. Additionally, the development of new technologies in wound care have helped to decrease morbidity and mortality in severe burn victims. Many examples can be given of the successful control of wound infection, such as the application of an appropriate antibiotic solution to invasive wound infection sites with simultaneous vacuum-assisted closure, optimal preservation of viable tissues with waterjet debridement systems, edema and exudate controlling dressings impregnated with Ag (Silvercel, Aquacell-Ag). The burned patient is at high risk for NI. Invasive interventions including intravenous and urinary chateterization, and entubation pose a further risk of NIs. The use of newly designed antimicrobial impregnated chateters or silicone devices may help the control of infection in these immunocomprimised patients. Strict infection control practices (physical isolation in a private room, use of gloves and gowns during patient contact) and appropriate empirical antimicrobial therapy guided by laboratory surveillance culture as well as routine microbial burn wound culture are essential to help reduce the incidance of infections due to antibiotic resistant microorganisms.

Burns are produced by contact with incense and treated with oil and vegetable dressings. Two cases are presented and discussed with reference to early Buddhist beliefs.

  1. Alcohol intoxication and post-burn complications.

    PubMed

    Choudhry, Mashkoor A; Chaudry, Irshad H

    2006-01-01

    Results from the studies discussed in this article suggest that alcohol (EtOH) intoxication is a major public health problem. While the effects of injury and EtOH intoxication independent of each other have been studied in detail, only few studies have evaluated the effect of a combined insult of EtOH intoxication and burn injury on host defense. An analysis of the studies conducted in the clinical setting suggests that intoxicated patients require frequent intubations, experience delayed wound healing and longer hospital stay. Furthermore, there is a greater risk of mortality in these patients compared to those who sustained injuries in the absence of EtOH intoxication. On the other hand, there are a few studies that do not support this notion. The results obtained in experimental models clearly suggest that acute EtOH intoxication before burn injury impairs host defense and increases susceptibility to infection. Additionally, experimental data from our laboratory also indicate that EtOH intoxication before burn injury suppresses intestinal immune defense, impairs gut barrier functions and increases bacterial growth. This results in increased bacterial translocation in EtOH and burn injury. In addition, a decrease in cardiac function is also reported following a combined insult of EtOH intoxication and burn injury. Altogether, these findings suggest that EtOH intoxication before burn injury diminishes host resistance resulting in increased susceptibility to infection. Moreover, the findings of a higher incidence of infectious complications in burn and trauma patients who sustained injury in the presence of EtOH compared to those in its absence suggest that EtOH intoxication at the time of injury is a risk factor. Therefore blood EtOH should be monitored in burn/trauma patients at the time of admission in the emergency room.

  2. Disseminated intravascular coagulation in burn injury.

    PubMed

    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.

    Summary The aim of the study was to examine the epidemiological characteristics of hospitalized burn patients in a tertiary burn centre in Tehran, Iran. A hospital-based cross-sectional study of all hospitalized patients with burn injuries was conducted in Motahari Burn and Reconstruction Center in Tehran from August to December 2010. Medical records of all hospitalized burn patients were reviewed and pertinent information was captured. A total of 135 patients with severe burns requiring hospitalization were identified during the study period (68.9% males, mean age 33 yr). The most common cause of burns was flammable materials/ liquids (e.g. kerosene and gasoline) (56/135, 41.5%). Binary logistic regression analysis showed that sex (female) and total body surface area (TBSA) burned were the strongest predictors of survival in this cohort. Our findings showed that burn injury continued to be a significant public health problem in Iran, young people (26-35 yr) being the most affected. TBSA and sex (female) were found to be the most predictive factors of patient survival. PMID:22262960

    Summary Burn care is one of the few areas in medicine considered both medically and surgically challenging, with burn injuries affecting people of all ages and both sexes. Between May 1992 and March 2012, 1,524 patients were admitted to the Lebanese Burn Center in Geitawi, with an average length of stay (LOS) of 36.5 days. The most frequently encountered injuries were thermal burns, generally resulting from domestic accidents. Of our patients, 47% were from rural areas and burned body surface (BBS) was the most serious factor, with 36% of all those admitted having suffered burns of 20% to 40% of their total body surface area (TBSA). Our team of experienced physicians, nurses, nutritionists and physical therapists was essential to successful burn care and outcomes were improved with adequate early fluid intake. The main causes of death were multiple organ failure due to hemodynamic instability, followed by respiratory failure from inhalation injury. A week after the injury, risk of infection was the main threat to the burn victims. Although this threat was compounded by malnutrition and immunodeficiency, excessive use of antibiotics was not justified. The fatality rate was about 18% and correlates with higher TBSA burns.

We described the process of care and outcome, including the accuracy of the SPUTOVAMO screening tool and examined child, burn and treatment characteristics related to suspicions of child abuse or neglect. A retrospective study was conducted in children aged 0-17 years with a primary admission after burn injuries to the burn centre Rotterdam in the period 2009-2013. Data on patient, injury and treatment characteristics were collected, using the Dutch Burn Repository R3. In addition, medical records were reviewed. In 498 paediatric admissions, suspected child abuse or neglect was present in 43 children (9%). 442 screening questionnaires (89%) were completed. In 52 out of 442 questionnaires (12%) the completed SPUTOVAMO had one or more positive signs. Significant independent predictors for suspected child abuse were burns in the genital area or buttocks (OR=3.29; CI: 143-7.55) and a low socio-economic status (OR=2.52; 95%CI: 1.30-4.90).

    Abstract. Frequent monitoring of early-stage burns is necessary for deciding optimal treatment and management. Both superficial and full thickness burns are relatively easy to diagnose based on clinical observation. In between these two extremes are superficial-partial thickness and deep-partial thickness burns. These burns, while visually similar, differ dramatically in terms of clinical treatment and are known to progress in severity over time. The objective of this study was to determine the potential of spatial frequency domain imaging (SFDI) for noninvasively mapping quantitative changes in chromophore and optical properties that may be an indicative of burn wound severity. A controlled protocol of graded burn severity was developed and applied to 17 rats. SFDI data was acquired at multiple near-infrared wavelengths over a course of 3 h. Burn severity was verified using hematoxylin and eosin histology. From this study, we found that changes in water concentration (edema), deoxygenated hemoglobin concentration, and optical scattering (tissue denaturation) to be statistically significant at differentiating superficial partial-thickness burns from deep-partial thickness burns.

    The US death rate from house fires has remained constant during the past 50 years despite a sharp decline in mortality from other fires and causes of burns. The concensus is that smoke alarms can effectively decrease the incidence of this lethal type of burn injury. Our organization of recovered burn patients has focused its efforts around procuring and installing smoke alarms in areas of substandard housing, which predominantly account for house fire deaths and injuries in St. Louis. This effort has resulted in an effective burn prevention program ("Alarms for Life"), which also serves as a model for other communities. PMID:3429488

    Background: Monopolar surgery is applied mostly in major operations, while bipolar is used in delicate ones. Attention must be paid in electrosurgery application to avoid electrical burns. Objectives: We aimed to assess factors associated with electrosurgery burns in cardiac surgery operating rooms. Patients and Methods: This was a case-control study in which two groups of 150 patients undergoing cardiac surgery in Imam Khomeini Hospital were recruited. Several factors like gender, age, operation duration, smoking, diseases, infection, atopia, , immunosuppressive drugs use, hepatic cirrhosis, and pulmonary diseases were compared between the two groups. Patients were observed for 24 hours for development of any burn related to the operation. Data was analyzed using SPSS v.11.5, by Chi square and T-test. Results: Patients in the two groups were similar except for two factors. DM and pulmonary diseases which showed significant differences (P = 0.005 and P = 0.002 respectively). Seventy-five patients from controls and 35 from the study group developed burns, which was significant (P ˂ 0.0001). Conclusions: None of the factors were significantly related to developing burns. The differences between the two groups highlights the importance of systems modifications to lessen the incidence of burns. PMID:26839854

    Measurements were made on the burning of liquid hydrazine, MMH, and UDMH in a combustion gas environment. The experimental range of these tests involved gas temperatures of 1660-2530 K, oxygen concentrations of 0-42% by mass and droplet diameters (employing both droplets and porous spheres) of 0.11-1.91 cm. at atmospheric pressure. A simplified hybrid combustion theory was developed which was found to correlate the present results as well as the experimental measurements of other investigators. Measurements were also made of the monopropellant strand burning rates and liquid surface temperatures of a number of nitrate ester fuels and hydrazine at elevated pressures. The temperature measurements for the nitrate esters were found to be in good agreement with a theoretical model which allowed for gas solubility in the liquid phase at high pressures. Experimental results were also obtained on the burning rates and liquid surface temperatures of a number of paraffin and alcohol fuels burning in air pressures up to 72 atm. For these tests, the fuels were burned from porous spheres in a natural convection environment. Initial findings on a pressurized flat flame burner are also described as well as the design of an oscillatory combustion apparatus to test the response of burning liquid fuels.

    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.

    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.

    Summary This paper presents various aspects of severe burns involving epileptic patients, who may suffer dramatic accidents during seizure attacks. Epileptics may fall onto an open fire or hot surface (e.g. a kitchen range) and they may upset containers full of boiling liquids, suffering deep burns and scalds. In our experience in this field, the most commonly affected body areas are the face and hands, the trunk, and the lower limbs. All such injuries are full-thickness burns, owing to the very long contact of the skin surface with the lesional agent. Three cases are presented of epileptics with severe burns who were admitted to the Burn Unit of Targu Mures Teaching Hospital, Romania, where they were hospitalized; conservative debridement using polyurethanefoam (PUR-foam) dressings was the standard procedure, which all the patients received. Split-thickness skin grafting was the final method for closing the granulating bed resulting from the conservative debridement. We have found that conservative debridement using PUR-foam dressings is a cheaper and more reliable alternative than sharp debridement (which may remove healthy tissue at the same time as burn eschars).

    In Egypt, low-income people often suffer burns because of the types of household fuels used and the lack of safety protection. Women and boys under the age of 5 years are the most vulnerable to this type of injury. This is because women do most of the cooking and because the stoves are on the floor, where they are easily over-turned by inquisitive, active youngsters. Women also suffer from intentional burns delivered as punishment by their husbands. When these burns result in death, the violence is labeled "suicide." Women also have a harder time receiving treatment than do men because the mobility of women is circumscribed, women's health is undervalued, and the treatment is lengthy. The Assiut project to treat burns has increased the status of female nurses who have received specific training in burn treatment. Treatment of female patients by male paramedics is also a new step that is leading to changes in the formalized male-female relationship found in rural Egyptian society. The project also takes into account the patient's right to rehabilitation, which is a novel idea in the Egyptian setting. Rehabilitation of women burn victims includes participation in group activities that generate income.

    The Fiber-Supported Droplet Combustion (FSDC) experiment team got more than twice as many burns have been completed as were originally scheduled for STS-95. This image was taken July 12, 1997, MET:10/08:13 (approximate). As shown here, scientists were able to burn two droplets side by side, more closely mimicking behavior of burning fuel in an engine. This shows ignition of a single drop that subsequently burned while a fan blew through the chamber, giving the scientists data on burning with convection, but no buoyancy -- an important distinction when you're trying to solve a problem by breaking it into parts. FSDC-2 studied fundamental phenomena related to liquid fuel droplet combustion in air. Pure fuels and mixtures of fuels were burned as isolated single and dual droplets with and without forced air convection. The FSDC guest investigator was Forman Williams, University of California, San Diego. The experiment was part of the space research investigations conducted during the Microgravity Science Laboratory-1R mission (STS-94, July 1-17 1997). Advanced combustion experiments will be a part of investigations plarned for the International Space Station.

  13. Burning in Outer Space: Microgravity

    NASA Technical Reports Server (NTRS)

    Matkowsky, Bernard; Aldushin, Anatoly

    2000-01-01

    A better understanding of combustion can lead to significant technological advances, such as less polluting, more fuel-efficient vehicles. Unfortunately, gravity can interfere with the study of combustion. Gravity drags down gases that are cooler- and, therefore, denser-than heated gases. This movement mixes the fuel and the oxidizer substance that promotes burning. Because of this mixing, an observer cannot necessarily distinguish what is happening as a result of the natural combustion process and what is caused, by the pull of gravity. To remove this uncertainty, scientists can conduct experiments that simulate the negation of gravity through freefall. This condition is known as a microgravity environment. A micro-gravity experiment may take place in a chamber that is dropped down a hole or from a high-speed drop tower. The experiment also be conducted in an airplane or a rocket during freefall in a parabolic flight path. This method provides less than a minute of microgravity at most. An experiment that requires the prolonged absence of gravity may necessitate the use of an orbiting spacecraft as a venue. However, access to an orbital laboratory is difficult to acquire. High-end computing centers such as the NCCS can provide a practical alternative to operating in microgravity. Scientists can model phenomena such as combustion without gravitys observational interference. The study of microgravity combustion produces important benefits beyond increased observational accuracy. Certain valuable materials that are produced through combustion can be formed with a more uniform crystal structure-and, therefore, improved structural quality-when the pull of gravity is removed. Furthermore, understanding how fires propagate in the absence of gravity can improve fire safety aboard spacecraft.

  14. Skin Burns Degree Determined by Computer Image Processing Method

    NASA Astrophysics Data System (ADS)

    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.

    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.

  16. Burned area, active fires and biomass burning - approaches to account for emissions from fires in Tanzania

    2013-04-01

    Eleven years of data from the globally available MODIS burned area and the MODS Active Fire Product have been analysed for Tanzania in conjunction with GIS data on land use and cover to provide a baseline for fire activity in this East African country. The total radiated energy (FRE) emitted by fires that were picked up by the burned area and active fire product is estimated based on a spatio-temporal clustering algorithm over the burned areas, and integration of the fire radiative power from the MODIS Active Fires product over the time of burning and the area of each burned area cluster. Resulting biomass combusted by unit area based on Woosteŕs scaling factor for FRE to biomass combusted is compared to values found in the literature, and to values found in the Global Fire Emissions Database (GFED). Pyrogenic emissions are then estimated using emission factors. According to our analysis, an average of 11 million ha burn annually (ranging between 8.5 and 12.9 million ha) in Tanzania corresponding to between 10 and 14 % of Tanzaniás land area. Most burned area is recorded in the months from May to October. The land cover types most affected are woodland and shrubland cover types: they comprise almost 70 % of Tanzania's average annual burned area or 6.8 million ha. Most burning occurs in gazetted land, with an annual average of 3.7 million ha in forest reserves, 3.3 million ha in game reserves and 1.46 million ha in national parks, totalling close to 8.5 million ha or 77 % of the annual average burned area of Tanzania. Annual variability of burned area is moderate for most of the analysed classes, and in most cases there is no clear trend to be detected in burned area, except for the Lindi region were annual burned area appears to be increasing. Preliminary results regarding emissions from fires show that for larger fires that burn over a longer time, biomass burned derived through the FRP method compares well to literature values, while the integration over

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

    Outcomes after burn have continued to improve over the last 70 years in all age groups including the elderly. However, concerns have been raised that survival gains have not been to the same magnitude in elderly patients compared to younger age groups. The aims of this study were to analyze the recent outcomes of elderly burn injured patients admitted to the Birmingham Burn Centre, compare data with a historical cohort and published data from other burn centres worldwide. A retrospective review was conducted of all patients ≥65 years of age, admitted to our centre with cutaneous burns, between 2004 and 2012. Data was compared to a previously published historical cohort (1999-2003). 228 patients were included. The observed mortality for the study group was 14.9%. The median age of the study group was 79 years, the male to female ratio was 1:1 and median Total Body Surface Area (TBSA) burned was 5%. The incidence of inhalation injury was 13%. Median length of stay per TBSA burned for survivors was 2.4 days/% TBSA. Mortality has improved in all burn size groups, but differences were highly statistically significant in the medium burn size group (10-20% TBSA, p≤0.001). Burn outcomes in the elderly have improved over the last decade. This reduction has been impacted by a reduction in overall injury severity but is also likely due to general improvements in burn care, improved infrastructure, implementation of clinical guidelines and increased multi-disciplinary support, including Geriatric physicians.

    After a burn injury, superficial partial-thickness burn wounds may progress to deep partial-thickness or full-thickness burn wounds, if kept untreated. This phenomenon is called secondary burn wound progression or conversion. Burn wound depth is an important determinant of patient morbidity and mortality. Therefore, reduction or even the prevention of secondary burn wound progression is one goal of the acute care of burned patients. The objective of this study was to review preclinical approaches evaluating therapies to reduce burn wound progression. A systematic review of experimental approaches in animals that aim at reducing or preventing secondary burn wound progression was performed in accordance with the Preferred Reporting Items for Systematic Reviews and Meta Analysis (PRISMA) guidelines. The selected references consist of all the peer-reviewed studies performed in vivo in animals and review articles published in English, German, Italian, Spanish, or French language relevant to the topic of secondary burn wound progression. We searched MEDLINE, Cochrane Library, and Google Scholar including all the articles published from the beginning of notations to the present. The search was conducted between May 3, 2012 and December 26, 2013. We included 29 experimental studies in this review, investigating agents that maintain or increase local perfusion conditions, as well as agents that exhibit an anti-coagulatory, an anti-inflammatory, or an anti-apoptotic property. Warm water, simvastatin, EPO, or cerium nitrate may represent particularly promising approaches for the translation into clinical use in the near future. This review demonstrates promising experimental approaches that might reduce secondary burn wound progression. Nevertheless, a translation into clinical application needs to confirm the results compiled in experimental animal studies.

    Intentional burns represent a serious form of physical abuse that must be identified to protect children from further harm. This study is a retrospectively planned secondary analysis of the Examining Siblings To Recognize Abuse (ExSTRA) network data. Our objective was to describe the characteristics of burns injuries in children referred to Child Abuse Pediatricians (CAPs) in relation to the perceived likelihood of abuse. We furthermore compare the extent of diagnostic investigations undertaken in children referred to CAPs for burn injuries with those referred for other reasons. Within this dataset, 7% (215/2890) of children had burns. Children with burns were older than children with other injuries (median age 20 months vs. 10 months). Physical abuse was perceived as likely in 40.9% (88) and unlikely in 59.1% (127). Scalds accounted for 52.6% (113) and contact burns for 27.6% (60). Several characteristics of the history and burn injury were associated with a significantly higher perceived likelihood of abuse, including children with reported inflicted injury, absent or inadequate explanation, hot water as agent, immersion scald, a bilateral/symmetric burn pattern, total body surface area ≥10%, full thickness burns, and co-existent injuries. The rates of diagnostic testing were significantly lower in children with burns than other injuries, yet the yield of skeletal survey and hepatic transaminases testing were comparable between the two groups. This would imply that children referred to CAPs for burns warrant the same level of comprehensive investigations as those referred for other reasons. PMID:27088728

    The number of asylum seekers in Ireland has increased dramatically over the last 10 years. Based on our impression that the number of children admitted to our burn unit was disproportionately represented by children of asylum seekers we performed an audit to establish (1) what proportion of admissions are from this subgroup and (2) the characteristics of their burns. All paediatric burn admissions from May 2003 to April 2004 were reviewed. Data collected from a retrospective chart review included patient demographics and details of the burn injuries. The National Census of 2002 and the Office of the Refugee Applications Commissioner were consulted for population statistics. Total burn admissions for the period were 126: Irish nationals (n=107), non-national residents (n=2), asylum seekers (n=14) and patients of unknown asylum status (n=3, excluded from study). In the asylum seeker group, the median age was 18.6 months (range 10 months-5.3 years) with the majority less than 2 years (n=11). All burns occurred in the domestic setting. Scalds accounted for 13 cases, one contact burn occurred from a hot grill. The median total body surface area burned was 5.7% (range 1.5-26%). The National Census of 2002 recorded a population of 3,917,203. With less than 12,000 asylum seekers in the country, they comprise only approximately 0.3% of the population yet they account for 11.4% of the burn patients admitted to our unit, p<0.0001. Children of asylum seekers are over-represented in our series of paediatric admissions for burns and are more likely than Irish children to sustain a burn at a younger age and in the domestic setting. This may indicate an increased risk of injury and warrants further investigation. PMID:16448770

    The purpose of this study was to retrieve data from the British Columbia Professional Firefighters Burn Unit registry, with a focus on ethnicity and how it is involved in burn trauma. It is hypothesized that mechanism, severity, and other patient characteristics are significantly different among different ethnic groups. Furthermore, it is believed that these data can be used to augment burn prevention strategies. Data for burn patients admitted from 1979 to 2009 were reviewed from the burn registry. The main focus was with differences seen among the four main ethnicities throughout the analysis, Caucasian, Aboriginal, Asian, and Indoasian, reflecting the population distribution of the region. Age and sex were also considered when looking at burn mechanism, severity, contributing and copresenting factors. Caucasians were the largest group (79.1%) and included the largest male:female ratio (3.3:1), with high numbers of flame injury (53.9%). Caucasians presented with the highest mortality (6.6% compared with 4.1% for all other ethnicities; P < .006). Asian patients (8.1%) showed significantly higher occurrences of urban (64%) and workplace (28.9%) injuries with a larger proportion of scald injury (38.9%). Indoasian patients included larger numbers of women (36.4%) and household scald injuries (33.9%) whereas Aboriginals suffered the most flame injuries (60.1%) in rural areas with more frequent contributing factors such as alcohol. The study found multiple significant differences in the burn injury population when segmented by ethnicity. Though the exact reasons for these differences are difficult to say with certainty, it allows a unique opportunity to focus communication and prevention efforts to specific communities.

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

    There is an emerging mechanism of burn injury as a result of the ignition of butane, during the manufacture of a tetrahydrocannabinol concentrate known as butane honey oil. The authors report of a series of patients who presented with this mechanism of injury and a description of the process that causes these burns. Patient data were gathered from the medical records of eight patients treated at the University of California Davis Medical Center and Shriners Hospital of Northern California. Information on the manufacturing process of butane honey oil was gathered from Internet searches and published literature on the topic. The burns witnessed at the abovementioned institutions ranged from 16 to 95% TBSA, with an average of 49.9%. The average length of stay for the patients was 118.3 hospital days and 114.4 intensive care unit days, with an average of 43.8 days spent on mechanical ventilation. The average age of patients was 22 years, with only one patient above the age of 30 years. Accidents during honey oil production have resulted in a surge of burn injuries in our community during the past year. The manufacture of this product, which involves the use of volatile butane gas, is gaining in popularity. Although considered to be safer than previous methods, multiple casualties with extensive burn injuries have resulted from this process. Associated injuries from blast trauma or chemical burns are not likely to occur in these types of explosions and have not been observed in the series reported in this article. In light of the increasing popularity of honey oil, it is important for burn care providers to gain awareness and understanding of this problem and its growing presence in the community.

  6. Hot bitumen burns: 92 hospitalized patients.

    Bitumen burns while comprising a small percentage of all types of burns are troublesome. They affect persons engaged in gainful employment which the burns then curtail, as well as requiring special attention because the substance adheres to the skin and is therefore difficult to remove. Ninety-two consecutive patients with such burns who were admitted as in-patients over a 10-year period (1985-1995) have been reviewed. Most of the burns occurred on a worksite and involved active young persons (mean age 29.6 years) the mean size of the burn was 3.87 per cent TBSA, mainly affecting the upper extremities and hands. Mean hospitalization time was 10.6 days. Bitumen burns are fully predictable and can easily be prevented by avoiding unsafe practice and/or equipment. Bitumen is a general term for petroleum-derived substances ranging from true petroleum through so-called mineral tars, to asphalt. Asphalt (Asphaltum) is a semi-solid mixture of several hydrocarbons probably formed by the evaporation of the lighter or more volatile constituents. It is amorphous of low specific gravity, 1-2, with a black or brownish black colour and pitchy lustre. At room temperature it is solid becoming molten and spreadable when heated to 93 degrees C and over. Roofing tars and asphalts are usually heated to temperatures of 232 degrees C to achieve desirable viscosities (e.g. for spraying), whereas lower temperatures are required for the manageable form to pave roads. Notable localities for asphaltum are the island of Trinidad and the Dead Sea region where lake asphaltums were long known to the ancient. Ironically, none of the 92 patients who were treated for bitumen injuries in the 'Soroka' (Beer-Sheba, Israel) and 'Barzilai' (Ashkelon, Israel) Medical Centres (80 and 150 km from the lake respectively) had anything to do with the Dead Sea area.

    Deep partial thickness burn (DPTB) wound fluids have a greater propensity for establishing neovascularization than did superficial partial thickness burn (SPTB) wound fluids in our previous study. To investigate the factors responsible for this activity, cytokine array and enzyme-linked immunosorbent assay were used to perform an expression analysis of angiogenic factors in burn fluid. Although present in approximately equal amounts in both SPTB and DPTB blister fluids from burn patients, angiogenin does appear to be involved in the ability of DPTB blister fluid to promote neovascularization in vitro and in vivo. Angiogenin alone was sufficient to induce endothelial differentiation of circulating angiogenic cells (CAC) without vascular endothelial growth factor A involvement. In addition, angiogenin was positively associated with CAC differentiation in the burn blister fluid. Blocking the effect of angiogenin in burn blister fluids resulted in a significant reduction of endothelial cell proliferation, CAC differentiation, and new blood vessels formation in vivo. Moreover, immunohistochemistry revealed that high angiogenin expression colocalizes with high vascularity in human burn wounds at day 7, further supporting our hypothesis that angiogenin is involved in burn wound neovascularization.

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

The program attracts preschoolers through preteens and is staffed by burn center personnel. The design consists of a small pool, a wooden fishing rod, several cutout fish, and hook-and-loop fasteners. Words that will stimulate interaction between the presenter and the participant are written on the fish; these can include "smoke detector," "cool the burn," "fire escape plan," "matches," "grease fire," and "120 degrees F." Providing an interactive, hands-on activity at health fairs can increase burn and fire safety awareness for the entire family.

    For more than a decade NIST conducted research to understand, measure and predict the important features of burning oil on water. Results of that research have been included in nationally recognized guidelines for approval of intentional burning. NIST measurements and predictions have played a major role in establishing in situ burning as a primary oil spill response method. Data are given for pool fire burning rates, smoke yield, smoke particulate size distribution, smoke aging, and polycyclic aromatic hydrocarbon content of the smoke for crude and fuel oil fires with effective diameters up to 17.2 m. New user-friendly software, ALOFT, was developed to quantify the large-scale features and trajectory of wind blown smoke plumes in the atmosphere and estimate the ground level smoke particulate concentrations. Predictions using the model were tested successfully against data from large-scale tests. ALOFT software is being used by oil spill response teams to help assess the potential impact of intentional burning. PMID:27500022

    Summary In Italy the economic crisis has caused changes in behavior in daily as well as leisure activities. For instance, night clubs have changed both their scenography and what they can offer. From simply providing a place to dance, they can now offer more complex scenography with spectacular fireworks and lit cocktails. While this can be amazing for all of us it can also be another cause of burn injuries. We conducted a retrospective study of all burns patients admitted to the Accident and Emergency Department at CTO Hospital in Turin from 2009 to 2013, after a night clubbing. A total of five patients were identified with an average age of 20 years old: four were burned by flaming cocktails and one was burned by a firework. Two received outpatient treatment, while orotracheal intubation and admission were needed for three, and two required surgical debridement and resurfacing with split skin graft. All patients had permanent sequelae caused by pathologic scarring and/or dyschromia. Our findings show that the risk of burn injuries is higher at weekends, mainly in summer, if all correct safety procedures are not followed. Meanwhile it is important to highlight that the promotion of inappropriate behavior at night clubs during firework displays and the passing of flaming cocktails should be avoided. PMID:26668565

    Measurements of biomass burn-produced trace gases were obtained using a helicopter at low altitudes above burning Florida wetlands on November 9, 1987, and from both helicopter and light-aircraft samplings on November 7, 1988. Carbon dioxide normalized emission ratios for carbon monoxide, hydrogen, methane, total nonmethane hydrocarbons, and nitrous oxide were obtained over burning graminoid wetlands consisting primarily of Spartina bakeri and Juncus roemerianus. Some interspersed scrub oak and saw palmetto were also burned. No significant differences were observed in the emission ratios determined for these gases from samples collected over flaming, mixed, and smoldering phases of combustion during the 1987 fire. Combustion-categorized differences in emission ratios were small for the 1988 fire. Combustion efficiency was relatively good (low emission ratios for reduced gases) for both fires. It is believed that the consistently low emission ratios were a unique result of graminoid wetlands fires, in which the grasses and rushes burned rapidly down to standing water and were quickly extinguished. Consequently, the efficiency of the combustion was good and the amount and duration of smoldering combustion was greatly deminished.

    The improved short and long term survival rate of individuals with large burn injuries has made rehabilitation for optimal recovery of the patient increasingly important. Burn injury to the hands worsens the prospect of functional recovery and good quality of life in single events, especially when included in larger burns. The purpose of this paper is to present a narrative review of examination strategies used for children with burn injuries to the hands in the acute, intermediate and long term stages of rehabilitation, and apply these concepts to selected treatments, using a case that is representative of this complex patient population. The model of health described by the World Health Organisation provided the framework for the review, to structure the review in the domains of body structures and body functions, functional activities and participation in life roles. The lack of consensus in the burn literature regarding the most appropriate outcome measures and interventions necessitates futures research and long term outcome studies to identify, predict and prevent the difficulties patients may face over their lifespan.

    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.

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

    Educational programs for clinicians managing patients with burn injuries represent a critical aspect of burn disaster preparedness. Managing a disaster, which includes a surge of burn-injured patients, remains one of the more challenging aspects of disaster medicine. During a 6-year period that included the development of a burn surge disaster program for one state, a critical gap was recognized as public presentations were conducted across the state. This gap revealed an acute and greater than anticipated need to include burn care education as an integral part of comprehensive burn surge disaster preparedness. Many hospital and prehospital providers expressed concern with managing even a single, burn-injured patient. While multiple programs were considered, Advanced Burn Life Support (ABLS), a national standardized educational program was selected to help address this need. The curriculum includes initial care for the burn-injured patient as well as an overview of the burn centers role in the disaster preparedness community. After 4 years and 56 classes conducted across the state, a survey was developed including a section that measured the perceptions of those who completed the ABLS educational program. The study specifically examines questions including whether clinicians perceived changes in their burn care knowledge, skills and abilities, and burn disaster preparedness following completion of the program? including whether clinicians.

    Measures taken during the Lebanon War, 1982, to prevent and minimize the extent and severity of tank-crew combat burns proved to be of value. Since 98% of tank crewmen who were burned were wearing fireproof suits at the time, only 12% sustained abdominal burns; 77% had facial burns, as none of them were wearing fireproof masks. Only 9% of the burned soldiers who wore fireproof gloves sustained hand burns, compared with 75% who did not wear the gloves. A comparison of the extent of tank-crew burns in the Lebanon War and the October 1973 War revealed that 51% of the burns in 1982 were minor, compared with 21% in 1973. Of the burns sustained in 1973, 29% covered greater than 40% of the body surface area, compared with 18% in 1982.

    This article describes an investigation of work-related burns in Washington State during 1994-1998. Workers' compensation data were used to describe the general characteristics of burn injuries, estimate industrial claims rates, and compare nonhospitalized and hospitalized burn cases. The completeness of workers' compensation data as a source for surveillance was evaluated. During 1994-1998, a total of 20,213 burn claims were accepted by the workers' compensation system. Hospitalized burn cases represented only 1.5% of burn claims but incurred 55% of the costs. In addition, workers' compensation data underestimated the frequency and rate of burns. Although workers' compensation claims rates decreased during 1994-1998, work-related burns remain a problem in Washington State. Several industries (e.g., roofing, foundries, and aluminum smelting) were identified as priorities for prevention of burn hospitalizations, which incur the greater cost and time loss.

    Burn depth and burn size are crucial determinants for assessing patients suffering from burns. Therefore, a correct evaluation of these factors is optimal for adapting the appropriate treatment in modern burn care. Burn surface assessment is subject to considerable differences among clinicians. This work investigated the accuracy among experts based on conventional surface estimation methods (e.g. "Rule of Palm", "Rule of Nines" or "Lund-Browder Chart"). The estimation results were compared to a computer-based evaluation method. Survey data was collected during one national and one international burn conference. The poll confirmed deviations of burn depth/size estimates of up to 62% in relation to the mean value of all participants. In comparison to the computer-based method, overestimation of up to 161% was found. We suggest introducing improved methods for burn depth/size assessment in clinical routine in order to efficiently allocate and distribute the available resources for practicing burn care.

    The influence of the initial fuel temperature on the burning behavior of n-heptane pool fire was experimentally studied at the State Key Laboratory of Fire Science (SKLFS) large test hall. Circular pool fires with diameters of 100mm, 141 mm, and 200 mm were considered with initial fuel temperatures ranging from 290 K to 363 K. Burning rate and temperature distributions in fuel and vessel wall were recorded during the combustion. The burning rate exhibited five typical stages: initial development, steady burning, transition, bulk boiling burning, and decay. The burning rate during the steady burning stage was observed to be relatively independent of the initial fuel temperature. In contrast, the burning rate of the bulk boiling burning stage increases with increased initial fuel temperature. It was also observed that increased initial fuel temperature decreases the duration of steady burning stage. When the initial temperature approaches the boiling point, the steady burning stage nearly disappears and the burning rate moves directly from the initial development stage to the transition stage. The fuel surface temperature increases to its boiling point at the steady burning stage, shortly after ignition, and the bulk liquid reaches boiling temperature at the bulk boiling burning stage. No distinguished cold zone is formed in the fuel bed. However, boiling zone is observed and the thickness increases to its maximum value when the bulk boiling phenomena occurs.

    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

    In order to predict the behavior of burning plasmas and develop optimized operation scenarios of ITER, integrated modeling and simulation of fusion plasmas is indispensable. Transport process is one of the main issues in integrated modeling of burning plasmas. In this lecture, first, aim of the integrated simulation, research activities of integrated modeling, desired features of integrated simulation codes, and the integrated tokamak simulation code, TASK, are briefly described. Then the present role of transport modeling in the integrated modeling is discussed based on the time scale separation. Basic equations of the transport simulation coupled with the equilibrium analysis are explained. Modeling of transport phenomena, comparison of transport models, simulation of internal transport barrier formation are described. After brief discussion of source modeling, an example of burning plasma simulation. Finally remaining issues are discussed and summaries are given.

    Local burn wound care represents an integral part in the treatment of burn victims. A primary treatment goal is to prevent superficial infections, which can lead to life-threatening bacteraemia and sepsis. Secondary goals include improvement of functional and aesthetic outcome of the regenerating skin or scar tissue. Within the last few years numerous innovations have been evolved and some have already been incorporated into the clinical routine. In line with this, the first mid-term studies can be found in the literature. For instance, a hydrosurgical system can now be used for debridement and novel skin substitutes like Suprathel and Matriderm are commercially available. This review article summarises the most recent innovations in local burn wound care and puts them into a scientific perspective.

    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.

    Patch burning can be a potential management tool to create grassland heterogeneity and enhance forage productivity and plant biodiversity, but its impacts on soil and environment have not been widely documented. In summer 2013, we studied the effect of time after patch burning (4 mo after burning [recently burned patches], 16 mo after burning [older burned patches], and unburned patches [control]) on vegetative cover, water erosion, and soil properties on a patch-burn experiment established in 2011 on a Yutan silty clay loam near Mead, NE. The recently burned patches had 29 ± 8.0% (mean ± SD) more bare ground, 21 ± 1.4% less canopy cover, and 40 ± 11% less litter cover than older burned and unburned patches. Bare ground and canopy cover did not differ between the older burned and unburned patches, indicating that vegetation recovered. Runoff depth from the older burned and recently burned patches was 2.8 times (19.6 ± 4.1 vs. 7.1 ± 3.0 mm [mean ± SD]) greater than the unburned patches. The recently burned patches had 4.5 times greater sediment loss (293 ± 89 vs. 65 ± 56 g m) and 3.8 times greater sediment-associated organic C loss (9.2 ± 2.0 vs. 2.4 ± 1.9 g m) than the older burned and unburned patches. The recently burned patches had increased daytime soil temperature but no differences in soil compaction and structural properties, dissolved nutrients, soil C, and total N concentration relative to older burned and unburned patches. Overall, recently burned patches can have reduced canopy and litter cover and increased water erosion, but soil properties may not differ from older burn or unburned patches under the conditions of this study.

    Burn wound infection (BWI) is a major public health problem and the most devastating form of trauma worldwide. Fungi cause BWI as part of monomicrobial or polymicrobial infection, fungaemia, rare aggressive soft tissue infection and as opportunistic infections. The risk factors for acquiring fungal infection in burns include age of burns, total burn size, body surface area (BSA) (30–60%), full thickness burns, inhalational injury, prolonged hospital stay, late surgical excision, open dressing, artificial dermis, central venous catheters, antibiotics, steroid treatment, long-term artificial ventilation, fungal wound colonisation (FWC), hyperglycaemic episodes and other immunosuppressive disorders. Most of the fungal infections are missed owing to lack of clinical awareness and similar presentation as bacterial infection coupled with paucity of mycology laboratories. Expedient diagnosis and treatment of these mycoses can be life-saving as the mortality is otherwise very high. Emergence of resistance in non-albicans Candida spp., unusual yeasts and moulds in fungal BWI, leaves very few fungi susceptible to antifungal drugs, leaving many patients susceptible. There is a need to speciate fungi as far as the topical and systemic antifungal is concerned. Deep tissue biopsy and other relevant samples are processed by standard mycological procedures using direct microscopy, culture and histopathological examination. Patients with FWC should be treated by aggressive surgical debridement and, in the case of fungal wound infection (FWI), in addition to surgical debridement, an intravenous antifungal drug, most commonly amphotericin B or caspofungin, is prescribed followed by de-escalating with voriconazole or itraconazole, or fluconazole depending upon the species or antifungal susceptibility, if available. The propensity for fungal infection increases, the longer the wound is present. Therefore, the development of products to close the wound more rapidly, improvement in

    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.

    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.

    Failed burn resuscitation can occur at various points. Early failed resuscitation will be largely caused by prehospital factors. During resuscitation, failure will present as a patient's nonresponse to adjunctive therapy. Late failure will occur in the setting of multiple organ dysfunction syndrome. Burn care providers must be vigilant during the resuscitation to identify a threatened resuscitation so that adjunctive therapies or rescue maneuvers can be used to convert to a successful resuscitation. However, when a patient's resuscitative course becomes unsalvageable, transition to comfort care should be taken to avoid prolongation of suffering. PMID:27600128

Neither criterion is validated based on either published property values or experimental evidence. Inconsistencies in published property values and definitions are noted. Computer calculations provide a more appropriate descriptions of the compositions of the combustion products and the adiabatic flame temperature of a burning metal at equilibrium. Dissociation temperatures (and product compositions) for 11 metals are computed using a specified quantity of thermal energy and compared with adiabatic flame temperatures.

    Emissions of methane from various sources of biomass burning are determined quantitatively for tropical, temperate, and boreal regions. About 85% of the total CH{sub 4} is emitted in the tropical area, which is mainly the result of shifting cultivation, fuelwood use, and deforestation. Methane emissions from biomass burning may have increased by at least 9% during the last decade because of increases in tropical deforestation and the use of fuelwood. Changes in land use practices and population growth in the tropics are possible causes of the increase of atmospheric CH{sub 4} concentration. 31 refs., 1 fig., 4 tabs.

    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.

In fact, the observed evidence of healing and improvement of the burns suggested healing effects from plasma irradiation. The quantities of neovascular vessels in the living tissues at 7 days were 9.2 ± 0.77 mm-2 without treatment and 18.4 ± 2.9 mm-2 after plasma irradiation.

    On a global scale, the total biomass consumed by annual burning is about 8680 million tons of dry material; the estimated total biomass consumed by the burning of savanna grasslands, at 3690 million tons/year, exceeds all other biomass burning (BMB) components. These components encompass agricultural wastes burning, forest burning, and fuel wood burning. BMB is not restricted to the tropics, and is largely anthropogenic. Satellite measurements indicate significantly increased tropospheric concentrations of CO and ozone associated with BMB. BMB significantly enhances the microbial production and emission of NO(x) from soils, and of methane from wetlands.

    Background To investigate the effects of platelet-rich plasma on tissue maturation and burn healing in an experimental partial-thickness burn injury model. Material/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. PMID:27262706

    Linezolid is effective on many resistant organisms for the treatment of severe infections in burns. However, its pharmacokinetics was difficult to predict after major burns. The study aimed to describe the pharmacokinetic properties of linezolid administered intravenously at a dose of 10 mg/kg in severely burned rabbits in comparison to that in non-burns. Linezolid concentrations were quantitatively analyzed by high-performance liquid chromatography. The direct consequence of the physiological changes after burn injury was lower plasma linezolid concentrations. In addition, burn injury induced significantly altered pharmacokinetic parameters with higher inter-individual variability. The distribution volume and clearance rate were increased (2.88 vs. 1.92 L/kg, P > 0.05; 0.28 vs. 0.20 L/h/kg, P < 0.05), and the AUC0-∞ was significantly lower (37.99 vs. 51.47 mg/L h, P < 0.05). However, there were almost no changes in half-life and mean residence time. These results suggested that therapeutic drug monitoring and dosage individualization of linezolid in patients with severe burns were necessary.

    An understanding of population-specific variation in pediatric burn injuries is essential to the development of effective prevention strategies. The purpose of this study was to examine the etiology of pediatric burn injury considering age and race categories using the National Burn Repository. The authors reviewed the records of all pediatric patients (age <18 years) in the American Burn Association's National Burn Registry injured between 1995 and 2007. The authors compared patient and injury characteristics across race, age, etiology, and payor status. A total of 46,582 patients were included in this study. The etiology of burn injury varied by both age and race. Populations of color were younger, constituting 53.8% of patients younger than 5 years, whereas 53.9% of the total study population identified as Caucasian. Scald etiology was disproportionately less common in patients identifying as Caucasian (39.9 vs 61.4%, P < .001), and scald was a common etiology in older children identifying as African American, Asian, and Hispanic. Inhalation injuries were also higher in patients identifying as Native American (5.4%), Hispanic (4.2%), and African American (3.7%). Pediatric burn injury etiology varies with age and race. These data should encourage careful consideration of race, age, and other differences in formulating the most effective, population-specific prevention and outreach strategies.

    2013-12-01

    The uncertainty in black carbon (BC) analysis and our inability to directly quantify the BC sources in the atmosphere has led to the uncertainty in compiling a regional or global BC emission inventory attributed to biomass burnings. We initiate this study to demonstrate a new approach, which quantifies the source of BC in the atmosphere between biomass and fossil fuel burnings. We applied the newly developed multi-element scanning thermal analysis (MESTA) technology to quantify BC and organic carbon (OC), respectively, in aerosol samples. MESTA can also separate BC from OC for subsequent radiocarbon analyses. Because fossil fuel has been depleted of radiocarbon and biomass has radiocarbon of the modern atmospheric level, we can quantify the sources of BC between fossil fuel and biomass burnings. We sampled the PM2.5 in the ambient air of central Tallahassee and its rural areas during the May-June (prescribed burning) and Nov-Dec (non-burning) periods. The results indicate that biomass burning contributed 89×1% and 67×2% of BC, respectively, during May-June and Nov.-Dec. periods. The rest of PM2.5 BC was contributed from fossil fuel burning. The radiocarbon contents of the OC was 103.42×0.55 percent modern carbon (pmC), which is consistent with the current atmospheric level with a trace of the bomb radiocarbon remained from the open atmosphere nuclear testing.

    Accurate prediction of mortality following burns is useful as an audit tool, and for providing treatment plan and resource allocation criteria. Common burn formulae (Ryan Score, Abbreviated Burn Severity Index (ABSI), classic and revised Baux) have not been compared with the standard Acute Physiology and Chronic Health Evaluation II (APACHEII) or re-validated in a severely (≥20% total burn surface area) burned population. Furthermore, the revised Baux (R-Baux) has been externally validated thoroughly only once and the pediatric Baux (P-Baux) has yet to be. Using 522 severely burned patients, we show that burn formulae (ABSI, Baux, revised Baux) outperform APACHEII among adults (AUROC increase p<0.001 adults; p>0.5 children). The Ryan Score performs well especially among the most at-risk populations (estimated mortality [90% CI] original versus current study: 33% [26-41%] versus 30.18% [24.25-36.86%] for Ryan Score 2; 87% [78-93%] versus 66.48% [51.31-78.87%] for Ryan Score 3). The R-Baux shows accurate discrimination (AUROC 0.908 [0.869-0.947]) and is well-calibrated. However, the ABSI and P-Baux, although showing high measures of discrimination (AUROC 0.826 [0.737-0.916] and 0.848 [0.758-0.938]) in children), exceedingly overestimates mortality, indicating poor calibration. We highlight challenges in designing and employing scores that are applicable to a wide range of populations.

    The elderly constitute an expanding subgroup within society, and may have differences in health needs compared to younger patients. The specific needs and outcomes of elderly patients with burns have been widely studied. However, the definition of elderly often used in previous studies is a cut off of 65 years old. Within this broadly defined group, the very elderly may have distinct health care needs and issues. This study investigated aetiology, management and outcome of burns in those over 90 years treated at a single UK burns service over a period of 15 years between 1998 and 2013, and compares these data to published data describing 'younger' elderly burns patients. Twenty two patients were included, with a 2:1 female:male ration, and a mean 9%TBSA burn. Six of the 22 died during their admission, and those who survived averaged 8 days inpatient stay per %TBSA. The very elderly with burns may fare worse than younger elderly patients. Although burns in the very elderly are relatively infrequent events, they require significant resource. Further work to optimise their outcome is required.

    Summary Understanding the cost of burn treatment is very important for patients, their families, governmental authorities and insurance companies. It alleviates patient and familial stress, provides a framework for better use of resources, and facilitates better performance between burn centers. Hospital burn costs can provide a basis for authorities to budget for acute burn treatment, for further management of chronic complications, and for planning prevention and public educational programs in Iran. To identify costs we used data from our burn registry program. Over the two-year assessment period, we treated roughly 28,700 burn patients, 1,721 of whom were admitted, with a mortality rate of 5.9%. The male to female ratio was 1.7:1 (63% male; 37% female). Flame burns were most frequent (49.8%) followed by scalds (35.7%). Mean hospital stay was 14.41 days (range 0-64 days). Mean TBSA was 17.39%. Skin grafts were carried out in 65.4% of the patients, with a mean of 5.2 surgeries per patient. The total cost of all patient admissions over the two years was US$ 4,835,000. The maximum treatment cost for one patient was US$ 91,000. The mean cost per patient was US$ 2,810 (29,500,000 Rials). The mean cost for each percent of burn was US$ 162. The mean cost for a one-day stay in hospital was US$ 195. The mean cost of each operation was US$ 540.

    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 <125, light blue 125-250, and green 250-440 PU. The thickness of these scars was significantly different between the predominant colours of 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.

    The aim of this study is to assess primary burn prevention knowledge in a rural Zambian population that is disproportionately burdened by burn injuries. A 10-question survey was completed by youths, and a 15-question survey was completed by adults. The survey was available in both English and Nyanja. The surveys were designed to test their knowledge in common causes, first aid, and emergency measures regarding burn injuries. Logistic regression analysis was used to explore relationships between burn knowledge, age, school, and socioeconomic variables. A burn prevention coloring book, based on previous local epidemiological data, was also distributed to 800 school age youths. Five hundred fifty youths and 39 adults completed the survey. The most significant results show knowledge deficits in common causes of burns, first aid treatment of a burn injury, and what to do in the event of clothing catching fire. Younger children were more likely to do worse than older children. The adults performed better than the youths, but still lack fundamental burn prevention and treatment knowledge. Primary burn prevention data from the youths and adults surveyed demonstrate a clear need for burn prevention and treatment education in this population. In a country where effective and sustainable burn care is lacking, burn prevention may be a better investment to reduce burn injury than large investments in healthcare resources.

    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.

  15. Burning mouth syndrome: a review and update.

    Silvestre, Francisco J; Silvestre-Rangil, Javier; López-Jornet, Pía

    2015-05-16

    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.

  16. Light microscopy of microfractures in burned bone.

    PubMed

    Schmidt, Christopher W; Uhlig, Rose

    2012-01-01

    Bone color changes depending upon the taphonomic agents that affect it. Burning turns bone black, brown, blue, gray, and white as the bone's temperature increases and collagen is lost. It also creates diagnostic fractures that are visible at the gross level. Usually heat-altered bone is readily identified as such, but there are times when dark organic stains can mimic bone that is charred black. This paper provides a means to observe and quantify microfractures in burned bone for those instances when macroscopic observations fail to clarify if a bone fragment is actually burned; specifically, it distinguishes charred from organically stained bone. It is based upon a study of 50 calcined (burned to a bright white), charred, and organically stained bone fragments (n = 150) that were viewed with a standard stereomicroscope at ×30. Microfractures are readily discerned on charred and calcined bones, being more common on the latter; they are not present on organically stained bone. Charred bones may have their cortical surfaces obscured by a microlayer of adhering soft tissues as well as by microflaking of the external circumferential lamella. Overall, the methods described here allow the detection of microfractures on bone using a very simple approach and readily available technology.

    A new thermal perfusion probe operates by imposing a thermal event on the tissue surface and directly measuring the temperature and heat flux response of the tissue with a small sensor. The thermal event is created by convectively cooling the surface with a small group of impinging jets using room temperature air. The hypothesis of this research is that this sensor can be used to provide practical burn characterization of depth and severity by determining the thickness of non-perfused tissue. The measurement system was tested with a phantom tissue that simulates the blood perfusion of tissue. Different thicknesses of plastic were used at the surface to mimic layers of dead tissue. The sensor uses a parameter estimation procedure with analytical solutions of the Pennes bio-heat equation to determine effective values of blood perfusion, core temperature, and thermal contact resistance. Twelve different thicknesses of plastic were used along with three different flow rates of perfusate to simulate burned skin in the phantom perfusion system. The resulting values of thermal contact resistance for the complete set of measurements correlate well with the layer thickness. The values are also nearly independent of the flow rate of the perfusate, which shows that the parameter estimation can successfully separate these parameters. These results with simulated burns show the value of this minimally invasive technique to predict the burn depth in tissue.

    The interindividual variability of imipenem pharmacokinetic parameters in burn patients suggest that these parameters have to be estimated with a large number of patients. The aim of this study is (i) to estimate these parameters with a population pharmacokinetic approach, and (ii) to test the influence of factors on pharmacokinetics parameters. Data are provided by therapeutic drug monitoring (n = 47,118 samples) and analysed by a nonlinear mixed effect modelling method. Among the tested covariates (age, gender, body weight, height, size of burn and creatinine plasma level) creatinine plasma level affects imipenem pharmacokinetic parameters substantially. The best fit is obtained with a two-compartment model integrating a linear-inverse relationship between imipenem clearance and creatinine plasma level. The estimates of imipenem clearance (16.37 +/- 0.204 L/h) and of the distribution volume of the central compartment (0.376 +/- 0.039 L/kg) are higher in the population of burn patients than the estimates in healthy subjects. This result is connected with high values of glomerule filtration rate and confirms the interest of therapeutic drug monitoring of imipenem in burn patients and particularly for patients with extreme values of creatinine clearance.

    2015-11-01

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

    Burns may represent one of the main indications for face allotransplantation. Severely disfigured faces featuring a devastating appearance and great functional impairments are not only seen as burn sequelae, but also occur as a result of other traumatic injuries, oncological surgical resections, benign tumors (e.g., neurofibromatosis), and major congenital malformations. To date, sixteen human face composite tissue allotransplantations have been performed with success. Despite the initial scepticism about its applicability, due mainly to ethical and technical reasons, the previous worldwide cases and their associated positive outcomes –including acceptable immunosuppressive regimens, excellent aesthetic and functional results, and good psychological acceptance by the recipient- , enable the conclusion that face composite tissue allotransplantation has become another therapeutic strategy in the reconstructive surgical armamentarium, which bears special consideration when dealing with severely disfigured burned patients. The aim of this review is to describe the basics of face composite tissue allotransplantation and give an overview of some of the cases performed until now, with special attention paid to debating the pros and cons of its applicability in burn patients.

    BACKGROUND: The burn eschar serves as a medium for bacterial growth and a source of local and systemic infection. To prevent or minimize these complications, it is important to debride the eschar as early as possible. OBJECTIVE: To identify the presence of viable skin within the excisions by examining tangentially excised burn eschars. METHODS: A total of 146 samples of burned human tissue were removed during 54 routine sharp tangential excision procedures (using dermatomes). The samples were histologically examined to identify the relative thickness of the dead, intermediate and viable layers. RESULTS: The mean (± SD) thickness of the excised samples was 1.7±1.1 mm. The sacrificed viable tissue (mean thickness 0.7±0.8 mm) occupied 41.2% of the entire thickness of the excision. In 32 biopsies (21.8%; 95% CI 16.0 to 29.3), the excision did not reach viable skin. Only eight biopsies (5.4%; 95% CI 2.8 to 10.1) contained all of the necrotic tissue without removing viable tissue. CONCLUSIONS: The thickness of a single tangentially excised layer of eschar is not much greater than the actual thickness of the entire skin and often contains viable tissue. Because surgical debridement is insufficiently selective, more selective means of debriding burn eschars should be explored. PMID:21886431

    A project on droplet combustion, pursued jointly with F.L. Dryer of Princeton University, has now been in progress for many years. The project involves experiments on the burning of single droplets in various atmospheres, mainly at normal atmosperic pressure and below, performed in drop towers and designed to be performed aboard space-based platforms such as the Space Shuttle or the Space Station. It also involves numerical computations on droplet burning, performed mainly at Princeton, and asymptotic analyses of droplet burning, performed mainly at UCSD. The focus of the studies rests primarily on time-dependent droplet-burning characteristics and on extinction phenomena. The presentation to be given here concerns the recent research on application of asymptotic methods to investigation of the flame structure and extinction of hydrocarbon droplets. These theoretical studies are investigating the extent to which combustion of higher hydrocarbons - heptane, in particular - can be described by four-step reduced chemistry of the kind that has achieved a good degree of success for methane flames. The studies have progressed to a point at which a number of definite conclusions can now be stated. These conclusions and the reasoning that led to them are outlined here.

    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.

    Accidental radioisotope burns are rare. The major components of radiation injury are burns, interstitial pneumonitis, acute bone marrow suppression, acute renal failure and adult respiratory distress syndrome. Radiation burns, though localized in distribution, have systemic effects, and can be extremely difficult to heal, even after multiple surgeries. In a 25 year old male who sustained such trauma by accidental industrial exposure to Iridium192 the early presentation involved recurrent haematemesis, pancytopenia and bone marrow suppression. After three weeks he developed burns in contact areas in the left hand, left side of the chest, abdomen and right inguinal region. All except the inguinal wound healed spontaneously but the former became a non-healing ulcer. Pancytopenia and bone marrow depression followed. He was treated with morphine and NSAIDs, epidural buprinorphine and bupivicaine for pain relief, steroids, antibiotics followed by wound excision and reconstruction with tensor fascia lata(TFL) flap. Patient had breakdown of abdominal scar later and it was excised with 0.5 cm margins up to the underlying muscle and the wound was covered by a latissimis dorsi flap. Further scar break down and recurrent ulcers occurred at different sites including left wrist, left thumb and right heel in the next two years which needed multiple surgical interventions.

Respirable airborne particulate containing these phases may present an occupational health hazard. Following from an earlier pilot study (J. S. Le Blond, B. J. Williamson, C. J. Horwell, A. K. Monro, C. A. Kirk and C. Oppenheimer, Atmos. Environ., 2008, 42, 5558-5565) in which experimental burning of sugarcane leaves yielded crystalline silica, here we report on actual conditions during sugarcane burning on commercial estates, investigate the physico-chemical properties of the cultivated leaves and ash products, and quantify the presence of crystalline silica. Commercially grown raw sugarcane leaf was found to contain up to 1.8 wt% silica, mostly in the form of amorphous silica bodies (with trace impurities e.g., Al, Na, Mg), with only a small amount of quartz. Thermal images taken during several pre-harvest burns recorded temperatures up to 1056 degrees C, which is sufficient for metastable cristobalite formation. No crystalline silica was detected in airborne particulate from pre-harvest burning, collected using a cascade impactor. The sugarcane trash ash formed after pre-harvest burning contained between 10 and 25 wt% SiO(2), mostly in an amorphous form, but with up to 3.5 wt% quartz. Both quartz and cristobalite were identified in the sugarcane bagasse ash (5-15 wt% and 1-3 wt%, respectively) formed in the processing factory. Electron microprobe analysis showed trace impurities of Mg, Al and Fe in the silica particles in the ash. The absence of crystalline silica in the airborne emissions and lack of cristobalite in trash ash suggest that high temperatures during pre-harvest burning were not sustained long enough for cristobalite to form, which is supported by the presence of low temperature sylvite and calcite in the residual ash.

    2010-01-01

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

  1. Total intravenous anesthesia for major burn surgery

    Total intravenous anesthesia (TIVA) is frequently used for major operations requiring general anesthesia in critically ill burn patients. We reviewed our experience with this approach. Methods: During a 22-month period, 547 major burn surgeries were performed in this center’s operating room and were staffed by full-time burn anesthesiologists. The records of all 123 TIVA cases were reviewed; 112 records were complete and were included. For comparison, 75 cases were selected at random from a total of 414 non-TIVA general anesthetics. Some patients had more than one operation during the study: as appropriate for the analysis in question, each operation or each patient was entered as an individual case. For inter-patient analysis, exposure to 1 or more TIVAs was used to categorize a patient as member of the TIVA group. Results: Excision and grafting comprised 78.2% of the operations. 14 TIVA regimens were used, employing combinations of 4 i.v. drugs: ketamine (K, 91 cases); i.v. methadone (M, 62); fentanyl (F, 58); and propofol (P, 21). The most common regimens were KM (34 cases); KF (26); KMF (16); and K alone (8). Doses used often exceeded those used in non-burn patients. TIVA was preferred for those patients who were more critically ill prior to surgery, with a higher ASA score (3.87 vs. 3.11). Consistent with this, inhalation injury (26.7 vs. 1.6%), burn size (TBSA, 36.3 vs. 15.8%), and full-thickness burn size (FULL, 19.8 vs. 6.5%) were higher in TIVA than in non-TIVA patients. Despite this, intraoperative pressor use was as common in TIVA as in non-TIVA cases (23.9 vs. 22.7%). Conclusions: TIVA was used in patients whose inhalation injury rate and TBSA were greater than those of non-TIVA patients. TIVA cases were not associated with increased hemodynamic instability. TIVA is a viable approach to general anesthesia in critically ill burn patients. PMID:23638329

    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.

    Burn injuries are a significant medical problem, and need to be treated quickly and precisely. Burned skin needs to be removed early, within hours (less than 24 hrs) of injury, when the margins of the burn are still hard to define. Studies show that treating and excising burn wounds soon after the injury prevents the wound from becoming deeper, reduces the release of proinflammatory mediators, and reduces or prevents the systemic inflammatory reaction syndrome. Also, removing burned skin prepares the affected region for skin grafting. Raman spectroscopy could be used as an objective diagnostic method that will assist burn surgeons in removing burned skin precisely. As a first step in developing a diagnostic tool, we present Raman spectroscopy information from normal and burned ex vivo rat skin, and a comparison of our findings. Raman spectroscopy is explored for its specificity and sensitivity.

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

    Summer camp is reported to be a positive and valuable experience for burn and nonburned children. Objective studies comparing the effectiveness, similarities, and differences of rehabilitative vs recreational camps are limited. The aim of this study, year 1, was to assess the effect of burn camp on self-esteem and integration as reported by burn children via the Rosenberg Self-Esteem Scale and a community integration survey. During year 2, burn campers completed these measures again and their self-esteem and integration scores were compared with a group of nonburn campers. The first year results showed significant improvement in burn camper's self-esteem from the beginning to end of camp and successful integration into the camp community. During year 2, burn surviving children reported significantly lower self-esteem before camp than the comparison group, but after camp, burn children's self-esteem was comparable with that of nonburn campers. White non-Hispanic campers reported more sustained improvement in self-esteem than other ethnic groups. Burn campers reported a high level of integration into the camp across sex, years since burn, years at camp, or ethnicity, scoring slightly higher than the comparison group. Age was positively correlated with integration among the burn, but not the nonburn campers. Helping children deal with their burn injuries through a rehabilitative program such as burn camp appears to provide benefit for child burn survivors.

  10. Mechanical hole-burning spectroscopy: Demonstration of hole burning in the terminal relaxation regime

    Shi, Xiangfu; McKenna, Gregory B.

    2006-01-01

    We have developed a mechanical spectral hole-burning (MSHB) scheme that is analogous to dielectric and magnetic spectral hole-burning techniques. Previous dielectric nonresonant spectral hole-burning experiments have been performed close to the glass temperatures of glass-forming materials and interpreted in terms of dynamic heterogeneity. The present study focuses on polymeric systems far above the glass temperature and in the terminal (reptation) regime. Theoretically, we examine Kaye-Bernstein-Kearsley-Zapas and Bernstein-Shokooh nonlinear viscoelastic constitutive models, which do not invoke an explicit heterogeneous dynamics for the relaxation response, to study MSHB, and find that both models fail to capture the subtle mechanical holes observed in the experiments. Experimentally, we successfully burned mechanical holes and show that the hole intensities vary as a function of “waiting time” and pump amplitude. The results suggest that MSHB is a potentially powerful tool with which to examine the dynamics of complex fluids.

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

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

    Thermal injuries of more than 20% body surface area (BSA) result in systemic capillary leakage with subsequent edema. This can similarly be induced by burn plasma transfer (BPT) from burned individuals to healthy rats. We evaluated if cerium nitrate (CN) bathing can prevent edema after BPT. Therefore, donor rats (DR) underwent thermal injury (100 degrees C water, 30%BSA, 12 s) for positive controls and were additionally bathed in CN (0.05M, at 10 and 120 min) for study groups. For negative controls DR underwent shamburn (37 degrees C water, 30%BSA, 12 s). DR-plasma (harvested 4 h post trauma) was transferred to healthy individuals. Intravital microscopy was performed in mesenteric venules (0/60/120 min). Edema was assessed by FITC-albumin extravasation. Additionally, leukocyte sticking (cells/mm(2)) and micro hemodynamic parameters were assessed. Significant systemic capillary leakage was observed after BPT at 120 min. Edema formation was significantly lower in negative controls. Topical CN application after 10 and 120 min reduced FITC-efflux to baseline levels. Adherent leukocytes increased slightly in all groups. Leukocyte-sticking tended to be reduced after CN bathing. In conclusion, BPT induces burn edema in healthy individuals. CN bathing after 10 and 120 min reduces mediator levels in burned individuals. Therefore, BPT after CN application does not induce burn shock anymore. Burn edema is partially independent from leukocyte activation because CN significantly influences macromolecular leakage whereas leukocyte activation is not significantly altered.

  14. Subatmospheric burning characteristics of AP/CTPB composite propellants with burning rate modifiers

    While burning at subatmospheric pressure, composite propellant generally fume and under certain conditions eject partially reacted particles. This characteristic property is exploited in this study to understand the mechanism of burning rate modification. The additives CuCr{sub 2}O{sub 4}, Fe{sub 2}O{sub 3}, Sb{sub 2}O{sub 3}, Al(OH){sub 3} gel, and LiF were used with unmetallized AP/CTPB (carboxy terminated polybutadiene) composite propellants, and the following studies were done: burning rate measurements below and above atmospheric pressure (up to 70 bar); quantitative chemical analysis of fume deposits and ejected particles; and scanning electron microscope examination of the microstructure of the surface extinguished propellant samples. The results of the studies at subatmospheric pressure indicate that burning rate enhancers augment the AP/binder interfacial reactions, CuCr{sub 2}O{sub 4} decomposes into copper oxide and chromium oxide with net heat release, and if this occurs at the surface, it constitutes one route by which the burning rate could be enhanced, Fe{sub 2}O{sub 3} possibly enhances near-surface breakdown of heavy fuel molecules, and the melt layer on AP particles and the low-viscosity binder-melt, which exist when LiF is present in the propellants, possibly depress the burning rate.

    Long-term outcome of burn scars as well as the relation with clinically relevant parameters has not been studied quantitatively. Therefore, we conducted a detailed analysis on the clinical changes of burn scars in a longitudinal setup. In addition, we focused on the differences in scar quality in relation to the depth, etiology of the burn wound and age of the patient. Burn scars of 474 patients were subjected to a scar assessment protocol 3, 6, and 12 months postburn. Three different age groups were defined (≤5, 5-18, and ≥18 years). The observer part of the patient and observer scar assessment scale revealed a significant (p < 0.001) improvement in scar quality at 12 months compared with the 3- and 6-month data. Predictors for severe scarring are depth of the wound (p < 0.001) and total body surface area burned (p < 0.001). Etiology (p = 0.753) and age (p > 0.230) have no significant influence on scar quality when corrected for sex, total body surface area burned, time, and age or etiology, respectively.

    Patients who survive a major burn must live with emotional and physical sequela. In a literature review, we found that sexuality concerns of burn victims are rarely a focus of therapy. After suggestions from Rimmer et al. [12], using their questionnaire translated into Portuguese, we held a survey of burn-care professionals at the VII Brazilian Burn Congress. More than 120 practitioners from 41 centres, aged in average 41.2 years (1 standard deviation 10.96), completed the survey. A proportion of 63.7% were female, and 58.1% were Caucasians; 37.1% were physicians, 20.9% nurse practitioners and 16.9 were occupational therapists/physical therapists (OTs/PT)s. Psychologists made up 3.2%. Only 28% of the respondents felt comfortable in initiating a conversation about sexual intimacy with their patients. The vast majority believed it should be done by the psychologist. Only 38% felt their burn centre did an adequate job in that area. When compared with a study of our country's general population, we find similar results indicating that intimacy, sexuality and sexual intercourse are considered most important in a relationship. There is a significant lack of literature in sexuality after burn; most likely meaning it is ignored by most centres. There is a need for other similar surveys to be performed, as well as a collective consciousness of the need for discussions about sexuality with patients and their partners, providing counselling and treatment, when need.

    The major improvement in burn therapy is likely to focus on the early management of hemodynamic and respiratory failures in combination with an aggressive and early surgical excision and skin grafting for full-thickness burns. Immediate burn care by first care providers is important and can vastly alter outcomes, and it can significantly limit burn progression and depth. The goal of prehospital care should be to cease the burning process as well as prevent future complications and secondary injuries for burn shock. Identifying burn patients appropriate for immediate or subacute transfer is an important step in reducing morbidity and mortality. Delays in transport to Burn Unit should be minimized. The emergency management follows the principles of the Advanced Trauma Life Support Guidelines for assessment and stabilization of airway, breathing, circulation, disability, exposure and environment control. All patients with suspected inhalation injury must be removed from the enclosure as soon as possible, and immediately administer high-flow oxygen. Any patient with stridor, shortness of breath, facial burns, singed nasal hairs, cough, soot in the oral cavity, and history of being in a fire in an enclosed space should be strongly considered for early intubation. Fibroscopy may also be useful if airway damage is suspected and to assess known lung damage. Secondary evaluation following admission to the Burn Unit of a burned patient suffering a severe thermal injury includes continuation of respiratory support and management and treatment of inhalation injury, fluid resuscitation and cardiovascular stabilization, pain control and management of burn wound.

    Abstract Background: Differentiating between superficial and deep-dermal (DD) burns remains challenging. Superficial-dermal burns heal with conservative treatment; DD burns often require excision and skin grafting. Decision of surgical treatment is often delayed until burn depth is definitively identified. This study’s aim is to assess the ability of hyperspectral imaging (HSI) to differentiate burn depth. Methods: Thermal injury of graded severity was generated on the dorsum of hairless mice with a heated brass rod. Perfusion and oxygenation parameters of injured skin were measured with HSI, a noninvasive method of diffuse reflectance spectroscopy, at 2 minutes, 1, 24, 48 and 72 hours after wounding. Burn depth was measured histologically in 12 mice from each burn group (n = 72) at 72 hours. Results: Three levels of burn depth were verified histologically: intermediate-dermal (ID), DD, and full-thickness. At 24 hours post injury, total hemoglobin (tHb) increased by 67% and 16% in ID and DD burns, respectively. In contrast, tHb decreased to 36% of its original levels in full-thickness burns. Differences in deoxygenated and tHb among all groups were significant (P < 0.001) at 24 hours post injury. Conclusions: HSI was able to differentiate among 3 discrete levels of burn injury. This is likely because of its correlation with skin perfusion: superficial burn injury causes an inflammatory response and increased perfusion to the burn site, whereas deeper burns destroy the dermal microvasculature and a decrease in perfusion follows. This study supports further investigation of HSI in early burn depth assessment. PMID:26894016

    Diagnosis of burn depths is crucial to determine the treatment plan for severe burn patients. However, an objective method for burn depth assessment has yet to be established, although a commercial laser Doppler imaging (LDI) system is used limitedly. We previously proposed burn depth assessment based on photoacoustic imaging (PAI), in which thermoelastic waves originating from blood under the burned tissue are detected, and we showed the validity of the method by experiments using rat models with three different burn depths: superficial dermal burn, deep dermal burn and deep burn. On the basis of those results, we recently developed a real-time PAI system for clinical burn diagnosis. Before starting a clinical trial, however, there is a need to reveal more detailed diagnostic characteristics, such as linearity and error, of the PAI system as well as to compare its characteristics with those of an LDI system. In this study, we prepared rat models with burns induced at six different temperatures from 70 to 98 °C, which showed a linear dependence of injury depth on the temperature. Using these models, we examined correlations of signals obtained by PAI and LDI with histologically determined injury depths and burn induction temperatures at 48 hours postburn. We found that the burn depths indicated by PAI were highly correlative with histologically determined injury depths (depths of viable vessels) as well as with burn induction temperatures. Perfusion values measured by LDI were less correlative with these parameters, especially for burns induced at higher temperatures, being attributable to the limited detectable depth for light involving a Doppler shift in tissue. In addition, the measurement errors in PAI were smaller than those in LDI. On the basis of these results, we will be able to start clinical studies using the present PAI system.

    Rescuer burn is a relatively newer terminology introduced to define the burns sustained by a person attempting to rescue a primary burn victim. Few studies have been published thus far on this peculiar type of burns. Due to the general neglect of the rescuer burns victim and discontinuation of treatment in most cases, once the primary victim dies, the rescuer often ends up in badly infected wounds and has a delayed return to work. A prospective study was conducted at the B J Medical College and Civil Hospital, Ahmedabad from January 2009 to December 2012 on the rescuer burns patients treated in its burns and plastic surgery department. 3074 patients of burns received treatment during the period of study. Of these, 48 patients gave the history of sustaining burns while trying to rescue a burns victim. Male to female ratio of rescuers was approximately 7:1. It was significantly higher as compared to the ratio of 1:0.8 of females to male burn victims observed at our centre (p≤0.01). Average age of the rescuers was higher in males as compared to females but the difference was not significant (p≥0.05). Of the 45 cases of female primary burns victims, male rescuer was husband of the primary victim in 41/45 cases (91.1%), mother was rescuer in three cases (6.6% cases) and sister was rescuer in one case. Though multiple people came to rescue a burns victim, in all cases, it was seen that it was the first rescuer who sustained burns himself or herself. None of the rescuers had any knowledge of the techniques and precautions to be taken while performing a rescue operation irrespective of their education status, indirectly pointing to the lack of any teaching on burns rescue in the school education curriculum.

    The management of burns within the first hours of injury has a significant impact on mortality and morbidity. In case of burns disasters, most patients are managed by non-burn practitioners. The knowledge held by our local family physicians is thought to be representative of that of non-burn practitioners, as they had not partaken in any courses or training on burn management beyond graduation. With regard to emergency burn management, the knowledge required is: assessment of burn extent and depth, associated injuries, indications of escharotomy, fluid therapy and airway management, as well as safe transportation. The aim of this study therefore was to assess the knowledge of family physicians - as an indicator of that of non-burn practitioners - on emergency burn management, and design accordingly an appropriate burn educational program. An interview questionnaire was distributed to all physicians working in Family Medicine Centers in Ismailia, Egypt, who did not possess a post-graduate degree. A total of twenty-four family physicians (100%) participated in this study. The questionnaire findings showed that, out of a possible score of 25 correct answers, the highest result was 12; achieved by 6 physicians (25%). The highest frequency score was 8 correct responses; obtained by 10 physicians (29.2%). This demonstrated a knowledge deficit among Ismailia's family physicians, and subsequently non-burn practitioners, with regard to burns management, due to gaps in undergraduate teaching.

    Summary One focus of improvement of burn care in Ukraine was the management of blood loss and blood transfusions in burn patients. The aim of this project was to analyze blood transfusion triggers in burn patients and outcomes at eleven major burn centers in Ukraine. This multicenter retrospective study reviewed four years of data on blood-transfused burn patients admitted to eleven major burn centers in Ukraine. Data analyzed included: demographics, characteristics of the burns, complications of burn injury, triggers for blood transfusions and outcomes. A total of 928 burn patients who received 2,693 blood transfusions from 11 major burn centers over a four-year period, were studied. Regardless of the total body surface area (TBSA) that was burned, blood transfusions were administered with a hemoglobin (Hb) trigger value of around 9 g/dL. Roughly one third (30.5%) of all transfusions were given in patients with a TBSA ≤ 10%. We demonstrated that Ukrainian doctors were using the same Hb trigger for blood transfusions for all Ukrainian burn patients, which suggested a need to change blood transfusion policy. PMID:27279803

    It is established that at early stages of the burn disease (deep burn of III-B degree, 20% of body surface) in rats there appears metabolic acidosis, the content of urea increases in the liver and blood serum, a pronounced hydration of the liver and muscles is observed in the burn zone. Administration per os of carbostimulin just a day after burn removes symptoms of metabolic acidosis. When the preparation is fed to rats during 7 days after burn the intensity of radioactive label incorporation into proteins, lipid and glycogen of the liver as well as in proteins and lipids of kidneys and spleen increases.

The patient was hospitalized for 13 days in a Burns Intensive Care Unit, and was discharged for an ambulatory follow-up. The treatment of such burns does not differ from any conventional treatment for heat- induced second-degree burns. The physiopathology of the phytophotodermatitis induced by such homemade tanning solutions rich in psoralen is discussed in detail.

    The goal of this video is to educate school children to the potential hazards of open air trash burning; to demonstrate alternative ways to dispose of trash; and to motivate students to take action to change the behavior of their parents with regard to trash burning. The burning of household trash, although illegal, is still a common practice in rural areas of Delaware. Enforcement has been difficult because the practice is often performed at night and is done across a wide rural area that is difficult to patrol on a continuing basis. The prohibition on trash burning (revised Regulation 13 of The Delaware Code of Regulations Governing The Control of Air Pollution) has been in effect since 1968, but the public has been slow to comply because trash burning has been practiced for many generations and because much of the public is unaware of the environmental impacts and/or the human health risks. This video may be valuable for other States to use as a public outreach tool regarding their problems with open air refuse burning. The focus of the video is a 7th grade science class is given various assignments relating to Earth Day and preservation of natural resources. Two children in particular are given the assignment to research and report on the hazards of open air trash burning and are asked to investigate alternative ways to dispose of refuse. Upon brainstorming how to find information on the topic, the kids decide to contact the host of a popular children's science show on broadcast television named Proton Dan the Science Man (a fictitious character and show based on Bill Nye the Science Guy). The host then invites the kids to the studio where he films his show and takes them through the topic. The TV host character takes the children to several external locations like a landfill, recycling centers, etc..

    1986-01-01

    The report informs on ruptures within the area of the gastro-intestinal tract of two siblings (2 and 3 years of age) that were fatally burned in their apartment. The ruptures are obviously pointing to an "explosive-like" evaporation of the watery part of the gastro-intestinal contents under the influence of the heat, at impeded pressure balance through shrinking of the esophagus caused by the heat in the upper area and the closure of the pylorus. Of significance here is surely also the shrinking of the gastro-intestinal wall caused by the heat and the thin abdominal walls which were not likely to have acted as "heat insulators". These findings are a supplement to the burn hematoma of the stomach as described by Berg and Schumann (1985). PMID:3963991

    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

    Simultaneous tropospheric ozone and aerosols observed using the TOMS satellite instrument are reported for Madagascar during the 1979 through 1999 time period Ozone observations made using the TOMS tropospheric ozone convective-cloud differential method show that the tropospheric ozone amount associated with Madagascar has an average monthly value of 30 DU (Dobson units). The average value is enhanced by 10 to 15 DU in October This maximum coincides with the time of maximum biomass area burning in Madagascar and parts of southern Africa. The aerosol index derived from TOMS is examined for correlation with biomass burning in Madagascar and southern Africa. There is good correlation between a satellite observation derived fire index for different parts of Madagascar, tropospheric ozone and the TOMS aerosol index in the same geographical area. Aerosols from fires were found to reach their peak in November and to persist over Madagascar until sometime in December.

    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.

  5. 'Tertiary' nuclear burning - Neutron star deflagration?

    Michel, F. Curtis

    1988-01-01

    A motivation is presented for the idea that dense nuclear matter can burn to a new class of stable particles. One of several possibilities is an 'octet' particle which is the 16 baryon extension of alpha particle, but now composed of a pair of each of the two nucleons, (3Sigma, Delta, and 2Xi). Such 'tertiary' nuclear burning (here 'primary' is H-He and 'secondary' is He-Fe) may lead to neutron star explosions rather than collapse to a black hole, analogous to some Type I supernovae models wherein accreting white dwarfs are pushed over the Chandrasekhar mass limit but explode rather than collapse to form neutron stars. Such explosions could possibly give gamma-ray bursts and power quasars, with efficient particle acceleration in the resultant relativistic shocks. The new stable particles themselves could possibly be the sought-after weakly interacting, massive particles (WIMPs) or 'dark' matter.

    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.

    Hot tap water is a common source of household burn injury. The charts of all patients hospitalized for tap water scalds in Dane County, Wisconsin, during a ten-year period were reviewed. Of 33 patients, 29 (88%) had readily identifiable risk factors: 17 (52%) were children younger than 5 years; three (9%) were older than 65 years; ten (30%) were physically or mentally disabled. One additional person was burned in a nonhome environment. Of the five deaths, three occurred in children younger than 30 months, and two occurred in patients older than 70 years. Almost all of these injuries could have been prevented by lowering the temperature of the household water heater to below 54.4 degrees C (130 degrees F) and preferably between 48.9 and 51.7 degrees C (120 to 125 degrees F). Physicians can play an important role in the prevention of this type of injury.

    Burns are common in children but it is not always clear whether the burn is accidental or not. Child abuse should always be considered. We present two children in which the diagnosis only became clear after admission and further investigation. Patient A, a 15-month-old boy, had a burn on his left shoulder. The burn was assumed suspect in view of the unclear history given by the parents and a possible delay in their seeking help. The patient was ultimately diagnosed with impetigo bullosa and successfully treated with antibiotics. Patient B, a 24-month-old girl, had burns on both feet and her right hand, which were infected as a result of the delay in seeking help. The burns were identified as abuse-related. The child was removed from her mother's care and sent to a foster home. A well-defined work-up should be followed in case of burns in children. PMID:23171561

    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—This study uses Missouri's inpatient and outpatient E code data system to describe the demographic characteristics of Missouri children who suffered burn injuries during 1994 and 1995. Methods—Retrospective review of Missouri E code data. Results—Altogether 8404 children aged 0–14 years were treated for burn injuries in Missouri hospitals during 1994 and 1995. The rate of burn injury in Missouri children was 339 per 100 000/year. African-American boys 0–4 years living in urban counties were at increased risk. In addition, African-American girls ages 0–4 years living in counties with a high poverty rate had raised burn injury rates. Burns from hot objects and scalds from hot liquids caused more than half of the burns. Conclusions—Hospital based E coding has proven an invaluable tool for the study of burns and will, no doubt, prove equally useful for other injuries. PMID:11144622

    Two studies are described in this paper. In the first study 225 acutely, severely burned patients were retrospectively investigated as to admission blood alcohol level and history of chronic alcohol abuse. The influence of further risk factors, circumstances and therapeutic data was studied, in particular the influence of gender, full-thickness burns, smoke inhalation injury, smoking, length of total and ICU stay, and suicide attempt. The 70 patients with positive blood alcohol levels on admission had a significantly higher fatality rate (31.5 per cent) in comparison with the 18.1 per cent fatality rate of patients with a negative blood alcohol level. Both groups had nearly identical mean TBSA and mean age. Chronic alcohol abuse was noted in 59 patients. These patients were found to have a higher fatality rate (31.4 per cent, 22/70) compared with that of patients without a history of chronic alcohol abuse who had an overall fatality rate of 18.1 per cent (28/155). No significant difference was found between non-intoxicated and acutely intoxicated alcoholics (31.4 vs 29.3 per cent). Our conclusion is that intake of alcohol before burn injury represents an independent risk factor. The second study was a prospective study of 16 consecutively admitted burn patients, who were evaluated for both drug and alcohol intake. Five patients had positive drug levels and five had positive alcohol levels. Five patients had a history of chronic drug and/or alcohol abuse. This incidence of alcohol and drug abuse supports the findings of our retrospective study.

    Black carbon (BC) aerosol has relatively short atmospheric lifetimes yet plays a unique and important role in the Earth's climate system, making it an important short-term climate mitigation target. Globally, biomass burning is the largest source of BC emissions into the atmosphere. This study investigated the mass absorption efficiency (MAE) of biomass burning BC generated by controlled combustion of various wildland fuels during the Fire Laboratory at Missoula Experiments (FLAME). MAE values derived from a photoacoustic spectrometer (∼7.8 m2/g at a wavelength of 532 nm) were in good agreement with those suggested for uncoated BC when the emission ratios of organic carbon (OC) to elemental carbon (EC) were extremely low (i.e., below 0.3). With the increase of OC/EC, two distinct types of biomass smoke were identified. For the first type, MAE exhibited a positive dependence on OC/EC, while the overestimation of the light absorption coefficient (babs) by a filter-based method was less significant and could be estimated by a nearly constant correction factor. For the second type, MAE was biased low and correlated negatively with OC/EC, while the overestimation of babs by the filter-based method was much more significant and showed an apparent OC/EC dependence. This study suggests that BC emission factors determined by the commonly used thermal-optical methods might be sustantially overestimated for some types of biomass burning emissions. Our results also indicate that biomass burning emissions may include some liquid-like organics that can significantly bias filter-based babs measurements.

    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.

    An unusual case is reported in which a patient sustained a third-degree burn of the plantar surface of the right foot as the result of contact with a heating radiator. This occurred when the patient fell asleep in his hospital bed after knee surgery. Spinal anaesthesia is easy to perform, and the risk factors, though present, are not serious. Such accidents are not infrequent and care should be taken to prevent them.

  17. Apparatus for burning bales of trash

    SciTech Connect

    Pazar, C. A.

    1985-08-13

    Bales of combustible trash made to specific specifications are burned in a furnace having two parallel upright sidewalls between which the bales pass during burning. A horizontal grate extends between the sidewalls. The bales, if remotely made from the furnace, are bound by an easily meltable strap. The length of the bale is measurably smaller than the distance between said sidewalls to accurately accommodate springback. A ram, after compacting the waste in segmental fashion, pushes each bale to a position between said sidewalls; with the length of the bale being perpendicular to the sidewalls, so that a bale enters the furnace. Springback following the melting of straps allows the bale to expand to fill the gap between the sidewalls. This facilitates ignition and/or burning of the bales and provides a seal against furnace sidewalls. When the ram feeds a fresh bale, previously charged bales (consumed proportional to time in the furnace) are advanced toward the ash discharge port. Before the bales are formed, the trash may be optionally dried by using heated air in the classification into ''light'' sort and ''heavy'' sort. The ''light'' sort is baled and burned as described above. The ''heavy'' sort or a part of the light sort may be premixed with noxious liquid or solid wastes before charging to the furnace. Temperatures consistent with economical use of refractory (1500/sup 0/ F. to 1700/sup 0/ F.) are maintained, for a limited area adjacent the inner wall of the furnace, by addition of liquid water, while interior temperatures of the furnace of about 3000/sup 0/ F. prevail in the central portion of the furnace necessary for the incineration of noxious wastes.

    In this study a multi-temporal differenced Normalized Burn Ratio (dNBRMT) is presented to assess burn severity of the 2007 Peloponnese (Greece) wildfires. 8-day composites were created using the daily near infrared (NIR) and mid infrared (MIR) reflectance products of the Moderate Resolution Imaging Spectroradiometer (MODIS). Prior to the calculation of the dNBRMT a pixel-based control plot selection procedure was initiated for each burned pixel based on time series similarity of the pre-fire year 2006 to estimate the spatio-temporal NBR dynamics in the case that no fire event would have occurred. The dNBRMT is defined as the one-year post-fire integrated difference between the NBR values of the control and focal pixels. Results reveal the temporal dependency of the absolute values of bi-temporal dNBR maps as the mean temporal standard deviation of the one-year post-fire bi-temporal dNBR time series equaled 0.14 (standard deviation of 0.04). The dNBRMT's integration of temporal variability into one value potentially enhances the comparability of fires across space and time. In addition, the dNBRMT is robust to random noise thanks to the averaging effect. The dNBRMT, based on coarse resolution imagery with high temporal frequency, has the potential to become either a valuable complement to fine resolution Landsat dNBR mapping or an imperative option for assessing burn severity at a continental to global scale.

    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.
