    Full Text Available This study aimed to investigate the endothelial function in a canine model of burn injury combined with seawater immersion. The model of burn injury was established. The dogs were randomly divided into four groups including dogs with burn injury (B group, or burn injury combined with seawater immersion (BI group, or only immersion in seawater (I group, or control animals with no injury or immersion (C group. The circulating endothelial cell (CEC count and coagulation-fibrinolysis parameters were measured. The CEC count in B group increased at 4 h, 7 h, and 10 h after injury and then reduced, whereas it continuously increased to a greater extent in BI group (P<0.05. The von Willebrand factor (vWF activity, plasminogen activator inhibitor (PAI-1, and the ratio of thromboxane B2 (TXB2 to 6-keto-prostaglandin F1α (6-K-PGF1α in BI group had a marked increase after injury, and the tissue-type plasminogen activator (tPA in the BI group decreased. Microscope observations revealed thrombus formation in lungs of the animals in BI group, but not in C, I, or B groups. Burn injury causes endothelial dysfunction, and seawater immersion lastingly aggravates this injury, leading to a higher risk of developing thrombosis.

    Darok, M; Reischle, S


    About 1.4-26% burn injuries in children appear to be abusive in origin. A 2.5-year-old girl was referred to our institute because of suspected child abuse. Clinical examination and later interrogation of the mother revealed non-recent deep second degree burn injuries on both gluteal regions, caused by the partner of the mother by pressing a hand-held hair-dryer against the skin. The authors present the findings of this unusual method of child abuse.

  5. Burn Injuries: Burn Depth, Physiopathology and Type of Burns

    Directory of Open Access Journals (Sweden)

    Kemalettin Koltka


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

  6. Ventilator-associated pneumonia after combined burn and trauma is caused by associated injuries and not the burn wound. (United States)

    Eckert, Matthew J; Wade, Terence E; Davis, Kimberly A; Luchette, Fred A; Esposito, Thomas J; Poulakidas, Stathis J; Santaniello, John M; Gamelli, Richard L


    An increased risk of ventilator-associated pneumonia (VAP) has previously been demonstrated in trauma patients urgently intubated in the prehospital (ie, field) and emergency department (ED) settings. This study investigated the impact of urgent intubation on subsequent VAP in patients who sustained both a burn injury and a traumatic injury. We undertook a retrospective review of both trauma registry data and medical records for all patients with combined thermal and traumatic injuries admitted to a single verified burn center and level I trauma center. Patients undergoing field or ED intubation during the 5-year period ending December 2002 were identified and studied. Data abstracted included admission demographics and vital signs, presence of inhalation injury, location at the time of intubation, presence of associated injury, percentage TBSA burn, hospital and intensive care unit length of stay, and hospital day of VAP diagnosis. Seventy-eight of the 3388 patients (2.3%) admitted during the study period sustained a combination of burn wounds and trauma and underwent urgent field or ED intubation. The majority of patients were men (71%), with a mean age of 46 +/- 24 years. There was one failed oral intubation, which required cricothyroidotomy. The location of the patient at the time of intubation was ED, 66%; burn center ED, 17%; and field, 17%. Eighty percent of all patients were diagnosed with an inhalation injury. VAP was diagnosed in 39 patients (50%), with a mean time to diagnosis of 10 +/- 9 days. TBSA burn, smoke inhalation, and time (in days) to diagnosis of VAP were not independent risk factors for the occurrence of pneumonia in any of the 3 groups. However, those intubated at the initial ED were more likely to develop VAP (P = .028) compared to those intubated in the field or in the burn center. The incidence of associated injuries was significantly greater (P burn patients also sustain blunt trauma. VAP occurs in 50% of the patients requiring urgent

  10. LA50 in burn injuries. (United States)

    Seyed-Forootan, K; Karimi, H; Motevalian, S A; Momeni, M; Safari, R; Ghadarjani, M


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

  14. The biology of burn injury. (United States)

    Evers, Lars H; Bhavsar, Dhaval; Mailänder, Peter


    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.

  15. Serotonin syndrome caused by fentanyl and methadone in a burn injury. (United States)

    Hillman, Ashley D; Witenko, Corey J; Sultan, Said M; Gala, Gary


    Serotonin syndrome is a syndrome identified by a triad of altered mental status, neuromuscular overactivity, and autonomic instability caused by the overstimulation of serotonin in the central nervous system and periphery. Serotonin syndrome may be provoked with the addition or increase in serotonergic agents such as selective serotonin reuptake inhibitors, serotonin norepinephrine reuptake inhibitors, tricyclic antidepressants, and monoamine oxidase inhibitors as well as other agents with serotonergic properties. Some narcotics, including fentanyl and methadone, have these properties and may be associated with the development of serotonin syndrome when used in conjunction with other agents. Currently, there are no identified case reports of narcotics as the sole agent causing serotonin syndrome. This report provides a brief overview of serotonin syndrome, particularly with cases involving administration of narcotics such as fentanyl and methadone. The case described is the first report associated with fentanyl and methadone without the coadministration of other serotonergic agents, and a possible drug interaction with voriconazole is discussed. This raises awareness of using multiple serotonergic narcotics and the potential precipitation of serotonin syndrome.

  17. Firefighter burn injuries: predictable patterns influenced by turnout gear. (United States)

    Kahn, Steven A; Patel, Jignesh H; Lentz, Christopher W; Bell, Derek E


    Approximately 100 firefighters suffer fatal injuries annually and tens of thousands receive nonfatal injuries. Many of these injuries require medical attention and restricted activity but may be preventable. This study was designed to elucidate etiology, circumstances, and patterns of firefighter burn injury so that further prevention strategies can be designed. In particular, modification of protective equipment, or turnout gear, is one potential strategy to prevent burn injury. An Institutional Review Board-approved retrospective review was conducted with records of firefighters treated for burn injury from 2005 to 2009. Data collected included age, gender, TBSA, burn depth, anatomic location, total hospital days per patient, etiology, and circumstances of injury. Circumstances of injury were stratified into the following categories: removal/dislodging of equipment, failure of equipment to protect, training errors, and when excessive external temperatures caused patient sweat to boil under the gear. Over the 4-year period, 20 firefighters were treated for burn injury. Mean age was 38.9 ± 8.9 years and 19 of 20 patients were male. Mean burn size was 1.1 ± 2.7% TBSA. Eighteen patients suffered second-degree burns, while two patients suffered first-degree burns. Mean length of hospitalization was 2.45 days. Scald burns were responsible for injury to 13 firefighters (65%). Flame burns caused injury to four patients (20%). Only three patients received contact burns (15%). The face was the site most commonly burned, representing 29% of injuries. The hand/wrist and ears were the next largest groups, with 23 and 16% of the injuries, respectively. Other areas burned included the neck (10%), arm (6.5%), leg (6.5%), knees (3%), shoulders (3%), and head (3%). Finally, the circumstance of injury was evaluated for each patient. Misuse and noncontiguous areas of protective equipment accounted for 14 of the 20 injuries (70%). These burns were caused when hot steam

  18. Exercise following burn injury. (United States)

    de Lateur, Barbara J; Shore, Wendy S


    Fatigue is a major barrier to recovery for burned individuals. Studies indicate that a slow return to normal or near-normal muscle strength is the natural course of recovery. With no special interventions, other than the "usual care" tailored to the needs of the individual, postburn patients will make gradual improvement in strength and aerobic capacity. Using the principle of initial condition (the worse the initial condition, the greater the response to exercise intervention) the authors outline an augmented exercise program that should result in a robust improvement in aerobic capacity.

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

    Klein, Matthew B; Hollingworth, William; Rivara, Frederick P; Kramer, C Bradley; Askay, Shelley W; Heimbach, David M; Gibran, Nicole S


    Modern burn care is a resource intensive endeavor requiring specialized equipment, personnel, and facilities in order to provide optimum care. The costs associated with burn injury to both patients and society as a whole can be multifaceted and large. The purpose of this study was to evaluate the association between hospital costs, patient characteristics, and injury factors in a cohort of pediatric patients admitted to a regional burn center. We performed a review of the hospital charges accrued by pediatric patients (age dollar costs using an inflation index and a cost to charge ratio. Univariate and multivariate regressions were performed to identify the factors most significantly associated with cost. In addition, we performed a subset cost analysis for patients with burns more than 20% TBSA. A total of 1443 pediatric patients (age dollars was dollars 9026 (SD = dollars 25,483; median = dollars 2138). Area of full thickness burn was the only patient or injury factor significantly associated with greater hospital costs (P < .05) on multivariate analysis. No single anatomic area was associated with increased hospital costs when adjusted for total overall burn size. Injury severity was the most significant factor impacting index hospitalization costs following pediatric burn injury. Further studies defining the long-term societal costs impact of burn injury are needed as are studies that evaluate the impact of burn injury on quality of life.

    Objective: To explore the phenomenon of surviving burn injury and its associated issues and concerns. Methods: A cross sectional survey approach was utilized to obtain data from one hundred burn survivors who were purposely selected. Descriptive statistics and content analysis were used to analyze data. Results: Findings from the study indicate that burns from flames stood out as a major cause of burns. Physical discomfort/pain, anxiety, needing assistance in meeting self-care needs, financial and social limitations were identified as the major impact of the injury. Furthermore, participants perceived the existence of societal stigma. In addition, hope in God or a spiritual being as well as family support were the two key resources participants relied on to cope effectively. Conclusions: Surviving burn injury is associated with varied physical, social and psy-chological factors and survivors may need professional assistance to fully adjust after discharge.

  7. National programme for prevention of burn injuries

    Directory of Open Access Journals (Sweden)

    Gupta J


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

  10. Sexual Function Following Burn Injuries: Literature Review. (United States)

    Pandya, Atisha A; Corkill, Helen A; Goutos, Ioannis


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

  11. Oxidative stress and anti-oxidative mobilization in burn injury. (United States)

    Parihar, Arti; Parihar, Mordhwaj S; Milner, Stephen; Bhat, Satyanarayan


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

  12. Evaluation of burn injuries related to liquefied petroleum gas. (United States)

    Tarim, Mehmet Akin


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

  13. National trends in burn and inhalation injury in burn patients: results of analysis of the nationwide inpatient sample database. (United States)

    Veeravagu, Anand; Yoon, Byung C; Jiang, Bowen; Carvalho, Carla M; Rincon, Fred; Maltenfort, Mitchell; Jallo, Jack; Ratliff, John K


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

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

  15. Treating burns caused by hydrofluoric acid. (United States)

    Summers, Anthony


    Hydrofluoric acid is an ingredient of many common household and industrial solutions. Even seemingly minor burns caused by this acid can have catastrophic effects if they are treated inappropriately or late. This article describes the signs and symptoms, the pathophysiology and the emergency management of hydrofluoric acid burns.

  16. Medical management of paediatric burn injuries: best practice. (United States)

    Kim, Leo K P; Martin, Hugh C O; Holland, Andrew J A


    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.

  17. Epidemiology of burn injuries in Singapore from 1997 to 2003. (United States)

    Song, Colin; Chua, Alvin


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

  18. Burn injuries related to suicide. (United States)

    Persley, G V; Pegg, S P


    Of 1060 admissions to the burns unit, Royal Brisbane Hospital, over a 12-year period, there were 30 cases (2.8%) of attempted suicide. Fourteen (47%) of these patients died. The psychosocial features of people using self-ignition as a method of suicide are consistent with those of suicide in general. The morbidity if high and the outcome is often fatal, especially for those using a flammable liquid.

  19. Full thickness burn caused by exposure to giant hogweed: delayed presentation, histological features and surgical management.

    LENUS (Irish Health Repository)

    Chan, Jeffrey C Y


    We report the case of a 10-year-old boy with a full thickness chemical burn on his right pretibial area due to phytophotodermatitis (PPD) following contact with giant hogweed (Heracleum mantegazzianum). Although cutaneous burns due to plants are a well-established cause of chemical burn, previous reports described partial thickness burns that healed with conservative measures. This patient presented to our unit two weeks after the initial injury with an established full thickness burn. Debridement and split thickness skin grafting was required. We presented the histological features of the debrided skin specimen and discussed potential factors leading to this unexpected full thickness injury.

  20. Pattern of burn injury in hang-glider pilots. (United States)

    Campbell, D C; Nano, T; Pegg, S P


    High-voltage electrical injury has been well documented in a number of situations, such as the occupational hazard of linesmen and construction workers, and in the context of overhead railway power lines. Two cases of hang-glider pilots contacting 11,000-volt power lines have recently been treated in the Royal Brisbane Hospital Burns Unit. They demonstrate an interesting pattern of injury, not described in current burns literature, involving both hand and lower abdominal burns. Both patients sustained full-thickness patches of burn injury, with underlying muscle damage and peripheral neurological injury. This distribution of injury seems to be closely related to the design of the hang glider.

    differences between treatments in regard to skin erythema (P >.8), thermal or mechanical thresholds (P >.2), thermal or mechanical pain response (P >.2), or mechanical secondary hyperalgesia (P >.2). Dexamethasone had no analgesic effects in normal skin. CONCLUSIONS: The study indicates that systemic...... administration of dexamethasone 2 hours before a burn injury does not reduce the inflammatory-mediated changes in quantitative sensory thresholds, pain perception, or skin erythema in humans....... injury was produced on the medial aspect of the nondominant calf (12.5 cm2, 47 degrees C for 7 minutes). Quantitative sensory testing included pain ratings to thermal and mechanical stimuli (visual analog scale [VAS]), assessments of thermal and mechanical detection thresholds, and areas of allodynia...

  3. Airbag-related chest wall burn as a marker of underlying injury: a case report

    Directory of Open Access Journals (Sweden)

    Monkhouse Simon J


    Full Text Available Abstract Introduction This case of a man who sustained an airbag-induced thoracic injury and burn, highlights the potential harm that can be caused by airbags. It also serves to illustrate that a surface burn which looks small and benign can actually be a surface marker of a more serious injury. Staff working in emergency departments need to be aware of the risk of possible airbag-associated injuries. Case presentation A 65-year-old man was the driver in a frontal collision. He was wearing a seatbelt. The airbag was activated and caused a superficial chest wall burn. Initial chest x-rays were unremarkable but following deterioration in his condition, a computed tomography scan revealed a serious sternal fracture. The location of the fracture was marked on the surface by the burn. Conclusion Airbags can cause significant chest wall injuries and burns. Surface burns at the point of impact should not be dismissed as trivial as the forces involved can cause significant injury. We recommend that all people with chest wall injuries and/or burns due to airbags should have more detailed chest imaging as initial emergency radiographs can be falsely reassuring.

    Kendrick Denise


    Full Text Available Abstract Background Burn injuries remain one of the leading causes of injury morbidity and mortality in the World Health Organization's East Mediterranean Region. To provide an overview on the epidemiology of burn injuries in this region, a systematic review was undertaken. Methods Medline, Embase and CINAHL were searched for publications on burns in this region published between 01/01/1997 and 16/4/2007. Data were extracted to a standard spreadsheet and synthesised using a narrative synthesis. No attempt has been made to quantitatively synthesise the data due to the large degree of clinical heterogeneity between study populations. Results Seventy one studies were included in the review, from 12 countries. Burn injuries were found to be one of the leading causes of injury morbidity and mortality. The reported incidence of burns ranged from 112 to 518 per 100,000 per year. Burn victims were more frequently young and approximately one third of the victims were children aged 0-5 years. Hospital mortality ranged from 5 to 37%, but was commonly above 20%. Intentional self-harm burns particularly involving women were common in some countries of the region and were associated with a very high mortality of up to 79%. Conclusion Burn injuries remain an important public health issue in the East Mediterranean Region therefore further research is required to investigate the problem and assess the effectiveness of intervention programmes.

  5. Genitalia burn: accident or violence? Concerns that transcend injury treatment

    Directory of Open Access Journals (Sweden)

    Ana Lúcia Ferreira


    Full Text Available OBJECTIVE: To describe a case of genital burn which raised the suspicion of maltreatment (sexual abuse and neglect by lack of supervision.CASE DESCRIPTION: An infant was taken to the Emergency Room of a pediatric hospital with an extensive burn in the vulva and perineum. The mother claimed the burn had been caused by a sodium-hydroxide-based product. However, the injury severity led to the suspicion of sexual abuse, which was then ruled out by a multidisciplinary team, based on the consistent report by the mother. Besides, the lesion type matched those caused by the chemical agent involved in the accident and the family context was evaluated and considered adequate. The patient had a favorable outcome and was discharged after four days of hospitalization. Outpatient follow-up during six months after the accident enabled the team to rule out neglect by lack of supervision.COMMENTS: Accidents and violence are frequent causes of physical injuries in children, and the differential diagnosis between them can be a challenge for healthcare workers, especially in rare clinical conditions involving patients who cannot speak for themselves. The involvement of a multidisciplinary trained team helps to have an adequate approach, ensuring child protection and developing a bond with the family; the latter is essential for a continued patient follow-up.

    Burn injuries are tissue injuries originated as a result of a physical or chemical trauma. They can cause from a mild skin affectation to the total destruction of the affected tissues, depending on various levels of severity. Moreover, if the affected body surface is very large, patient life can seriously be compromised. In this chapter, the intention is to clarify the nursing care for the affected area, once patient's life risk is stabilized and controlled. This care should be based on an adequate approach to local handling of burn injuries, after their severity and prognosis have been stated. To do this, it will be used the standardized nursing language NNN, referring to Nursing Diagnosis NANDA (North American Nursing Diagnosis Association), Nursing Outcomes Classification (NOC) and Nursing Interventions Classification (NIC). This taxonomy is very useful to describe the Nursing clinical practice of burns care because it can easily be used by nurses participating in the care of this type of patients. Nursing plans using the NNN taxonomy can be designed using existing software applications.

  8. Do burns increase the severity of terror injuries? (United States)

    Peleg, Kobi; Liran, Alon; Tessone, Ariel; Givon, Adi; Orenstein, Arie; Haik, Josef


    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

  11. Children with burn injuries-assessment of trauma, neglect, violence and abuse

    Directory of Open Access Journals (Sweden)

    Antoinette Runge


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

    Sadeghi-Bazargani, Homayoun; Mohammadi, Reza; Ayubi, Erfan; Almasi-Hashiani, Amir; Pakzad, Reza; Sullman, Mark J. M.; Safiri, Saeid


    Purpose Burns are a common and preventable cause of injury in children. The aim of this study was to investigate child and caregiver characteristics which may predict childhood burn injuries among Iranian children and to examine whether confounding exists among these predictors. Methods A hospital based case-control study was conducted using 281 burn victims and 273 hospital-based controls, which were matched by age, gender and place of residence (rural/urban). The characteristics of the children and their caregivers were analyzed using crude and adjusted models to test whether these were predictors of childhood burn injuries. Results The age of the caregiver was significantly lower for burn victims than for the controls (Pcaregiver spent outdoors with the child and their economic status had a significant positive association with the odds of a burn injury (Pcaregivers was independently associated with the child's odds of suffering a burn injury (OR = 1.12, 95% CI: 1.04–1.21). The research also found that children with ADHD (Inattentive subscale: Crude OR = 2.14, 95% CI: 1.16–3.95, Adjusted OR = 5.65, 95% CI: 2.53–12.61; Hyperactive subscale: Crude OR = 1.73, 95% CI: 1.23–2.41, Adjusted OR = 2.53, 95% CI: 1.65–3.87) also had increased odds of suffering a burn injury. However, several variables were identified as possible negative confounder variables, as the associations were stronger in the multivariate model than in the crude models. Conclusion The caregiver's characteristics which were predictors of burn injuries among Iranian children were: being younger, high socio-economic status, Type A behavioural pattern and spending more time outdoors. In addition, the relationship between a child's ADHD scores and the odds of a burn injury may be negatively confounded by the caregivers predictor variables. PMID:28151942

    Full Text Available Severe burn injuries require high specialistic treatment. Burn injuries are common in disasters and war scenarios, so war medicine has been fundamental to improve treatment protocols for burn patients..Burn injuries are classified according to the etiopathogenetic agent (physical, chemical or radiation, that determines different anatomoisthologic aspects.An estimation of the depth and extension are fundamental for defining the gravity of the burn. Critical burn patients have to be transported in specialistic Centers. There they are treated by multispecialistic teams from the resuscitation phase to the reconstructive surgery and specialist rehabilitation.. This process can continue for two years with the objective to return patients to a quiet normal life. Les brûlures sont des lésions traumatiques qui requièrent un traitement spécialisé. Lors de catastrophes et de guerres, les brûlures sont des lésions très fréquentes et la médecine de guerre a contribué à faire avancer la science de manière importante, dans le traitement de cette pathologie.Les brûlures sont classées en fonction de l'agent étiopathogénique (agents physiques, chimiques ou radiations dont le mécanisme d'action qui provoque la lésion cause des aspects anatomohistologiques caractéristiques.Pour définir la sévérité d'une brûlure, il est aussi fondamental d'éstimer l'extension de la surface corporelle et la profondeur de l'épiderme, et éventuellement du derme, atteints. Les patients gravement brûlés doivent être hospitalisés dans des Centres Spécialisés où des équipes multispécialistes les suivent de la phase initiale de la réanimation aux phases de chirurgie reconstructive et au processus de réhabilitation. Ces dernières phases peuvent se prolonger pendant les deux années suivant le traumatisme avant qu'une réintégration dans une vie sociale acceptable ne puisse être faite.

  14. Myosin light chain kinase mediates intestinal barrier disruption following burn injury.

    Directory of Open Access Journals (Sweden)

    Chuanli Chen

    Full Text Available BACKGROUND: Severe burn injury results in the loss of intestinal barrier function, however, the underlying mechanism remains unclear. Myosin light chain (MLC phosphorylation mediated by MLC kinase (MLCK is critical to the pathophysiological regulation of intestinal barrier function. We hypothesized that the MLCK-dependent MLC phosphorylation mediates the regulation of intestinal barrier function following burn injury, and that MLCK inhibition attenuates the burn-induced intestinal barrier disfunction. METHODOLOGY/PRINCIPAL FINDINGS: Male balb/c mice were assigned randomly to either sham burn (control or 30% total body surface area (TBSA full thickness burn without or with intraperitoneal injection of ML-9 (2 mg/kg, an MLCK inhibitor. In vivo intestinal permeability to fluorescein isothiocyanate (FITC-dextran was measured. Intestinal mucosa injury was assessed histologically. Tight junction proteins ZO-1, occludin and claudin-1 was analyzed by immunofluorescent assay. Expression of MLCK and phosphorylated MLC in ileal mucosa was assessed by Western blot. Intestinal permeability was increased significantly after burn injury, which was accompanied by mucosa injury, tight junction protein alterations, and increase of both MLCK and MLC phosphorylation. Treatment with ML-9 attenuated the burn-caused increase of intestinal permeability, mucosa injury, tight junction protein alterations, and decreased MLC phosphorylation, but not MLCK expression. CONCLUSIONS/SIGNIFICANCE: The MLCK-dependent MLC phosphorylation mediates intestinal epithelial barrier dysfunction after severe burn injury. It is suggested that MLCK-dependent MLC phosphorylation may be a critical target for the therapeutic treatment of intestinal epithelial barrier disruption after severe burn injury.

  15. Using online blogs to explore positive outcomes after burn injuries. (United States)

    Garbett, Kirsty; Harcourt, Diana; Buchanan, Heather


    This study uses blog analysis, a new and novel technique, to explore the positive outcomes experienced by burn survivors. This study examined 10 burn survivor blogs to offer a unique, longitudinal insight into burn survivor recovery. Using thematic analysis, three themes emerged: shift in self-perception, enhanced relationships and a change in life outlook. Many of these themes contained stories and experiences unique to a traumatic burn injury, suggesting that standardised trauma scales are not effectively measuring the impact of a burn in this population. Reflections on blog analysis are discussed, along with a recommendation that health researchers utilise the vast amount of data available from online blogs.

    Background Severe burn-blast combined injury is a great challenge to medical teams for its high mortality. The aim of this study was to elucidate the clinical characteristics of the injury and to present our clinical experiences on the treatment of such cases.Methods Five patients with severe burn-blast combined injuries were admitted to our hospital 77 hours post-injury on June 7, 2005. The burn extent ranged from 80% to 97% (89.6%±7.2%) of TBSA (full-thickness burns 75%-92%(83.4%±7.3%)). All the patients were diagnosed as having blast injury and moderate or severe inhalation injury. Functions of the heart, liver, kidney, lung, pancreas and coagulation were observed. Autopsy samples of the heart, liver, and lungs were taken from the deceased. Comprehensive measures were taken during the treatment, including protection of organ dys function, use of antibiotics, early anticoagulant treatment, early closure of burn wounds, etc. All the data were analyzed statistically with t test.Results One patient died of septic shock 23 hours after admission (four days after injury), the others survived.Dysfunction of the heart, liver, lungs, pancreas, and coagulation were found in all the patients on admission, and the functions were ameliorated after appropriate treatments.Conclusions Burn-blast combined injury may cause multiple organ dysfunctions, especially coagulopathy. Proper judgment of patients' condition, energetic anticoagulant treatment, early closure of burn wounds, rational use of antibiotics, nutritional support, intensive insulin treatment, timely and effective support and protection of organ function are the most important contributory factors in successful treatment of burn-blast combined injuries.

  17. Interleukin-18 delays neutrophil apoptosis following alcohol intoxication and burn injury. (United States)

    Akhtar, Suhail; Li, Xiaoling; Kovacs, Elizabeth J; Gamelli, Richard L; Choudhry, Mashkoor A


    Studies have shown that burn patients who are intoxicated at the time of injury are more susceptible to infection and have a higher incidence of mortality. A major cause of death in burn and trauma patients regardless of their alcohol (EtOH) exposure is multiple organ dysfunction, which is driven in part by the systemic inflammatory response and activated neutrophils. Neutrophils are short lived and undergo apoptosis to maintain homeostasis and resolution of inflammation. A delay in apoptosis of neutrophils is one important mechanism which allows for their prolonged presence and the release of potentially harmful enzymes. The purpose of this study was to examine whether EtOH intoxication combined with burn injury influences neutrophil apoptosis and whether IL-18 plays any role in this setting. To accomplish this investigation, rats were gavaged with EtOH (3.2 g/kg) 4 h before being subjected to sham or burn injury of ~12.5% of the total body surface area, and then killed on d 1 after injury. Peripheral blood neutrophils were isolated and lysed. The lysates were analyzed for pro- and antiapoptotic proteins. We found that EtOH combined with burn injury prolonged neutrophil survival. This prolonged neutrophil survival was accompanied by a decrease in the levels of the neutrophil proapoptotic protein Bax, and an increase in antiapoptotic proteins Mcl-1 and Bcl-xl. Administration of IL-18 antibody following burn injury normalized the levels of Bax, Mcl-1 and Bcl-xl. The decrease in caspase-3 and DNA fragmentation observed following EtOH and burn injury was also normalized in rats treated with anti-IL-18 antibody. These findings suggest that IL-18 delays neutrophil apoptosis following EtOH and burn injury by modulating the pro- and antiapoptotic proteins.

    Full Text Available Ever since man invented fire he has been more frequently burning himself by this creation than by the naturally occurring bushfires. It is estimated that over 1.152 million people in India suffer from burn injuries requiring treatment every year and majority of them are women aged between 16-40 years and most of them occur in the kitchen. The treatment for burns basically involves autologous skin grafting, which originated in India more than two thousand years ago (Sushruta Samhita, is still the gold standard for the wound resurfacing, although, autografting is difficult where graftable donor sites are limited. Although, Cadaver skin, porcine or bovine xenografts are used alternatively over the past thirty years, modern approaches like the Bioengineering of skin substitutes emerged during the past 20 years as advanced wound management technologies with no social impediment. They can be broadly categorized as Acellular and Cellular biotechnological products. The acellular products like Alloderm (LifeCell Corporation, Integra (Integra Life Sciences act like template and depend on natural regeneration, while the cellular ones are either ‘Off-the-Shelf’ products like Apligraf (Organogenesis Inc and Orcel (Ortec International have allogenic elements and ‘home grown’ autologous cell products like Cultured Epithelial Autograft (CEA and epidermal-dermal composite skin use synthetic or natural non-human matrices. The CEA is based on the ex-vivo epidermal stem cell-expansion and our laboratory has been engaged in CEA technique development with innovative cost-effective approach and yielded promising preliminary clinical success. The basic methodological approach in CEA technique which is still clinically adopted by several developed countries involves the use of growth arrested mouse dermal fibroblasts as growth supportive matrix and is thus considered a drawback as a whole. Additionally, there is no superior enough method available to augment the

  19. Long-term persistance of the pathophysiologic response to severe burn injury.

    Directory of Open Access Journals (Sweden)

    Marc G Jeschke

    Full Text Available BACKGROUND: Main contributors to adverse outcomes in severely burned pediatric patients are profound and complex metabolic changes in response to the initial injury. It is currently unknown how long these conditions persist beyond the acute phase post-injury. The aim of the present study was to examine the persistence of abnormalities of various clinical parameters commonly utilized to assess the degree hypermetabolic and inflammatory alterations in severely burned children for up to three years post-burn to identify patient specific therapeutic needs and interventions. METHODOLOGY/PRINCIPAL FINDINGS: PATIENTS: Nine-hundred seventy-seven severely burned pediatric patients with burns over 30% of the total body surface admitted to our institution between 1998 and 2008 were enrolled in this study and compared to a cohort non-burned, non-injured children. Demographics and clinical outcomes, hypermetabolism, body composition, organ function, inflammatory and acute phase responses were determined at admission and subsequent regular intervals for up to 36 months post-burn. Statistical analysis was performed using One-way ANOVA, Student's t-test with Bonferroni correction where appropriate with significance accepted at p<0.05. Resting energy expenditure, body composition, metabolic markers, cardiac and organ function clearly demonstrated that burn caused profound alterations for up to three years post-burn demonstrating marked and prolonged hypermetabolism, p<0.05. Along with increased hypermetabolism, significant elevation of cortisol, catecholamines, cytokines, and acute phase proteins indicate that burn patients are in a hyperinflammatory state for up to three years post-burn p<0.05. CONCLUSIONS: Severe burn injury leads to a much more profound and prolonged hypermetabolic and hyperinflammatory response than previously shown. Given the tremendous adverse events associated with the hypermetabolic and hyperinflamamtory responses, we now identified

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

    Bras, Marijana; Loncar, Zoran; Brajković, Lovorka; Gregurek, Rudolf; Micković, Vlatko


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

    Jeschke, Marc G; Pinto, Ruxandra; Costford, Sheila R; Amini-Nik, Saeid


    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.

  3. Summer camps for children with burn injuries: a literature review. (United States)

    Maslow, Gary R; Lobato, Debra


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

    Full Text Available Abstract Background The management of burns remains a challenge in developing countries. Few data exist to document the extent of the problem. This study provides data from a suburban setting by documenting the epidemiology of burn injury and ascertaining outcome of management. This will help in planning strategies for prevention of burns and reducing severity of complications. Methods A total of 72 patients admitted for burns between January 1st, 2002 and December 31st, 2006 at the Irrua specialist teaching hospital were studied retrospectively. Sources of information were the case notes and operation registers. Data extracted included demographics as well as treatment methods and outcome Results The results revealed male to female ratio of 2.1:1. Over 50% of the injuries occurred at home. There was a seasonal variation with over 40% of injuries occurring between November and January. The commonest etiologic agent was flame burn from kerosene explosion. There were 7 deaths in the series. Conclusion Burns are preventable. We recommend adequate supply of unadulterated petroleum products and establishment of burn centers.

  5. Burn injury reduces neutrophil directional migration speed in microfluidic devices.

    Directory of Open Access Journals (Sweden)

    Kathryn L Butler

    Full Text Available Thermal injury triggers a fulminant inflammatory cascade that heralds shock, end-organ failure, and ultimately sepsis and death. Emerging evidence points to a critical role for the innate immune system, and several studies had documented concurrent impairment in neutrophil chemotaxis with these post-burn inflammatory changes. While a few studies suggest that a link between neutrophil motility and patient mortality might exist, so far, cumbersome assays have prohibited exploration of the prognostic and diagnostic significance of chemotaxis after burn injury. To address this need, we developed a microfluidic device that is simple to operate and allows for precise and robust measurements of chemotaxis speed and persistence characteristics at single-cell resolution. Using this assay, we established a reference set of migration speed values for neutrophils from healthy subjects. Comparisons with samples from burn patients revealed impaired directional migration speed starting as early as 24 hours after burn injury, reaching a minimum at 72-120 hours, correlated to the size of the burn injury and potentially serving as an early indicator for concurrent infections. Further characterization of neutrophil chemotaxis using this new assay may have important diagnostic implications not only for burn patients but also for patients afflicted by other diseases that compromise neutrophil functions.

    Full Text Available In nerve entrapment syndromes, an electrodiagnostic study during physical examination would usually suffice to assess localization of injury. However, in daily clinical practice, sometimes it may be necessary to depict the insight; in other words to use an imaging tool. From this point of view, with its manifold advantages, ultrasound (US is superior to other imaging technologies such as magnetic resonance imaging (MRI. According to a study, US increased the sensitivity of electrodiagnostic studies from 78% to 98%. By presenting a patient with cubital tunnel syndrome caused by hypertrophic scarring, we wanted to highlight the complementary role of US in nerve entrapment syndromes in confirming the entrapment, as well as the usefulness of it in the follow-up period of burn patients.

    Jeschke, Marc G; Boehning, Darren F; Finnerty, Celeste C; Herndon, David N


    After a severe burn, the liver plays a pivotal role by modulating inflammatory processes, metabolic pathways, immune functions, and the acute phase response. Therefore, liver integrity and function are important for recovery. A thermal injury, however, causes hepatic damage by inducing hepatic edema, fatty infiltration, hepatocyte apoptosis, and metabolic derangements associated with insulin resistance and impaired insulin signaling. In preliminary studies, we found that these pathophysiological processes are related to hepatic inflammation, altered intracellular signaling, and mitochondrial dysfunction. We hypothesize that modulation of these processes with insulin could improve hepatic structure and function and, therefore, outcome of burned and critically ill patients. Insulin administration improves survival and decreases the rate of infections in severely burned and critically ill patients. Here, we show that insulin administration decreases the synthesis of proinflammatory cytokines and signal transcription factors and improves hepatic structure and function after a severe burn injury; insulin also restores hepatic homeostasis and improves hepatic dysfunction postburn via alterations in the signaling cascade.

  9. Burning more than calories: treadmill friction injuries in children.

    Davidson, C C


    Treadmill injuries in young children are a serious but little documented problem. Friction burns occur when the hands come into contact with the moving belt resulting in deep burns that often require hospital admission and surgery. The aim of this study was to assess the nature and prevalence of injuries sustained and to highlight treadmill friction burns as a public health issue previously undocumented in Ireland. A retrospective chart review from January 2006 until March 2008 was performed and functional outcome was assessed by the modified Michigan Hand Outcomes Questionnaire. Eight girls and four boys from one year and seven months to seven years and five months were treated. Eight children required admission to hospital and to date three have required surgery for their injuries. This is a new and increasing problem in Ireland which must be highlighted.

  10. "Tetracycline hydrochloride chemical burn" as self-inflicted mucogingival injury: A rare case report

    Directory of Open Access Journals (Sweden)

    Mundoor Manjunath Dayakar


    Full Text Available Injuries to oral soft tissue can be accidental, iatrogenic, and factitious trauma. Chemical, thermal, and physical agents are the main causative agents for oral soft-tissue burns. The present case describes the chemical burn of oral mucosa caused by tetracycline hydrochloride and its management. Diagnosis was made on the basis of definitive history elicited from the patient. The early detection of the lesion by the patient and immediate institution of therapeutic measures ensure a rapid cure and possible prevention of further mucogingival damage. In addition, we believe that proper guidance and education of the patient is an important prophylactic measure in preventing this self-inflicting injury.

    Yang, Zong-cheng


    Although the outcome of burn patients has been improved, many aspects of management of severe burn patients remain controversial. Here we focus on the management of hypermetabolism and the resuscitation of respiratory function. Currently, the fluid resuscitation method shifts from insufficient fluid regimen to excessive fluid loading. The benefit of colloid infusion and restrictive blood transfusion need to be authenticated by further clinical trial, and the best form of fluid resuscitation has yet to be identified. The respiratory management of burn patients had been improved. Early tracheostomy, ventilation with low tidal volume and bronchoalveolar toilet are recommended. Many potential beneficial treatment strategies have been identified by recent research in the metabolic response to burn injury. Although immunomodulation therapy is promising, most of them are not clinical viable,and further clinical research is warranted.

    Bacterial infection is a major cause of morbidity affecting outcome following burn and inhalation injury. While experimental burn and inhalation injury animal models have suggested that mediators of cell damage and inflammation increase the risk of infection, few studies have been done on humans. This is a prospective, observational study of patients admitted to the North Carolina Jaycee Burn Center at the University of North Carolina who were intubated and on mechanical ventilation for treatment of burn and inhalational injury. Subjects were enrolled over a 2-yr period and followed till discharge or death. Serial bronchial washings from clinically indicated bronchoscopies were collected and analyzed for markers of tissue injury and inflammation. These include damage-associated molecular patterns (DAMPs) such as hyaluronic acid (HA), double-stranded DNA (dsDNA), heat-shock protein 70 (HSP-70), and high-mobility group protein B-1 (HMGB-1). The study population was comprised of 72 patients who had bacterial cultures obtained for clinical indications. Elevated HA, dsDNA, and IL-10 levels in bronchial washings obtained early (the first 72 h after injury) were significantly associated with positive bacterial respiratory cultures obtained during the first 14 days postinjury. Independent of initial inhalation injury severity and extent of surface burn, elevated levels of HA dsDNA and IL-10 in the central airways obtained early after injury are associated with subsequent positive bacterial respiratory cultures in patients intubated after acute burn/inhalation injury.

  20. Military and civilian burn injuries during armed conflicts. (United States)

    Atiyeh, B S; Gunn, S W A; Hayek, S N


    Burn injury is a ubiquitous threat in the military environment, and war burns have been described for more than 5,000 years of written history. Fire was probably utilized as a weapon long before that. With the ever-increasing destructive power and efficiency of modern weapons, casualties, both fatal and non-fatal, are reaching new highs, particularly among civilians who are becoming the major wartime targets in recent wars, accounting for most of the killed and wounded. Even though medical personnel usually believe that a knowledge of weaponry has little relevance to their ability to effectively treat injuries and that it may in some way be in conflict with their status, accorded under the Geneva and Hague treaties, it is imperative that they know how weapons are used and understand their effects on the human body. The present review explores various categories of weapons of modern warfare that are unfamiliar to most medical and paramedical personnel responsible for burn treatment. The mechanisms and patterns of injury produced by each class of weapons are examined so that a better understanding of burn management in a warfare situation may be achieved.

    This study utilized the "story grammar" approach (Stein and Glenn, 1979) to analyze the within-corpus differences in recounting of sixty 6- and 7-year-old children, specifically whether illustrations (5-factor accident sequence) were or were not resorted to as a means to assist their narration of a home accident in which a child received a burn injury from hot soup. Our investigation revealed that the message presentation strategy "combining oral and pictures" better helped young children to memorize the story content (sequence of events leading to the burn injury) than "oral only." Specifically, the content of "the dangerous objects that caused the injury", "the unsafe actions that people involved took", and "how the people involved felt about the severity of the accident" differed significantly between the two groups.

    The nitric oxide and cyclic GMP production in myocardium early after burn injury in tats were investigated. Nitric oxide synthase activity was measured in cytosols from the left ventricular wall of burned rats.Cytosols from the control group animals were shown to contain mainly Ca2+ dependent nitric oxide synthase (cNOS) with small amount of Ca2+ independent nitric oxide synthase (iNOS). Following burn injury,there was a marked increase in iNOS activity with a peak at 8h post-butyl, however, myocardial cNOS activity was found to decline obviously. Parallel to iNOS induction there was a significant increase in myocardial nitric oxide and cyelic GMP production. All these chenges were alleviated by treatment of the rats with dexamethasone. Since increases in cyclic GMP levels in the heart were associated with reduced myocardial contractility, it is possible that enhanced production of nitric oxide by a Ca2+ independent NO synthase accounts, at least in part, for the depression of myocardial contractility seen in burn animals and patients.

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

    Full Text Available INTRODUCTION: Platelet count evaluation in a burn trauma patient has much significance because it has been studied in literature that decrease i n platelet count is an indicator of septicaemia in the patient and vice versa thus knowing the count level of platelets, the treatment of burn patients can be done accordingly. Septicaemia is most important cause of mortality in burn patients, the survival of the patients can only be assured if septicaemia is detected early and controlled. Platelet s play an important role in haemostaticdisorder and immune response impairment in burn patient . [1] The aim of study is to see the significance of platelet count i nvestigation in burn patient and then their outcome, whether survival or not survival. MATERIAL METHODS: We investigated 480 burn patients within the ages of 18 and 60 Years and the percentage of the burn was between 20% and 70%. Platelet count was investi gated by visual method in all patients. The investigation of the platelet count was done on day 1, 3, 7, 14 & 21 of the patients. Other parameters TLC , neutrophil count was done by visual methods. Serum creatinine estimation was also done in all patients. RESULT: In our study we found that the platelet count gradually increased towards normal count and maintained till the discharge in survival patients, and in non - survival the platelet count gradually declined. The statistical significant of difference in m ean platelet counts on different post burn days in survivors and non survivors were studied by using standard t test. It was observed that the actual difference between two means is more than double of the SED between two means in different post burn days – i . e. , (Day 1, 3, 7, 14 &, 21. So difference is significant (P<0.05. CONCLUSION: It can be concluded that platelet count decreases initially in all cases of burn sepsis. It gradually rises to normal in case of survivors and declines gradually in non surv ivors. So serial declining

    Full Text Available Background: Burn injuries are one of the main causes of mortality and morbidity throughout the world and burn patients have higher chances for infection due to their decreased immune resistance. Levamisole, as an immunomodulation agent, stimulates the immune response against infection. Materials and Methods: This randomized clinical trial was conducted in Motahari Burn Center, Tehran, Iran. Patients who had second- or third-degree burn with involvement of more than 50% of total body surface area (TBSA were studied. The levamisole group received levamisole tablet, 100 mg per day. Meantime, both the levamisole and control groups received the standard therapy of the Burn Center, based on a standard protocol. Then, the outcome of the patients was evaluated. Results: 237 patients entered the study. After excluding 42 patients with inhalation injury, electrical and chemical burns, and the patients who died in the first 72 h, 195 patients remained in the study, including 110 patients in the control group and 85 in the treatment group. The mean age of all patients (between 13 to 64 years was 33.29 ± 11.39 years (Mean ± SD, and it was 33.86 ± 11.45 years in the control group and 32.57 ± 11.32 years in the treatment group.

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

  13. Management of a Patient With Faciocervical Burns and Inhalational Injury Due to Hydrofluoric Acid Exposure. (United States)

    Yuanhai, Zhang; Xingang, Wang; Liangfang, Ni; Chunmao, Han


    Hydrofluoric acid, a highly dangerous substance, can cause tissue damage and systemic toxicity by its unique mechanisms. Many cases of severe faciocervical burns due to hydrofluoric acid exposure are lethal. Herein, we present a case of 37-year-old man who suffered from hydrofluoric acid burns to his face, anterior neck, lips, and nasal cavity. On admission, this patient coughed with much sputum, and the chest auscultation detected rough breath sounds, wheezes, and very weak heart sounds, indicating possible inhalation injury. This case highlights the extreme complexity of managing this kind of injury. Timely and accurate wound treatment and respiratory tract care, as well as active systematic support treatment, played vital roles in the management of this patient.

  14. Review of Adult Electrical Burn Injury Outcomes Worldwide: An Analysis of Low-Voltage vs High-Voltage Electrical Injury. (United States)

    Shih, Jessica G; Shahrokhi, Shahriar; Jeschke, Marc G

    The aims of this article are to review low-voltage vs high-voltage electrical burn complications in adults and to identify novel areas that are not recognized to improve outcomes. An extensive literature search on electrical burn injuries was performed using OVID MEDLINE, PubMed, and EMBASE databases from 1946 to 2015. Studies relating to outcomes of electrical injury in the adult population (≥18 years of age) were included in the study. Forty-one single-institution publications with a total of 5485 electrical injury patients were identified and included in the present study. Fourty-four percent of these patients were low-voltage injuries (LVIs), 38.3% high-voltage injuries (HVIs), and 43.7% with voltage not otherwise specified. Forty-four percentage of studies did not characterize outcomes according to LHIs vs HVIs. Reported outcomes include surgical, medical, posttraumatic, and others (long-term/psychological/rehabilitative), all of which report greater incidence rates in HVI than in LVI. Only two studies report on psychological outcomes such as posttraumatic stress disorder. Mortality rates from electrical injuries are 2.6% in LVI, 5.2% in HVI, and 3.7% in not otherwise specified. Coroner's reports revealed a ratio of 2.4:1 for deaths caused by LVI compared with HVI. HVIs lead to greater morbidity and mortality than LVIs. However, the results of the coroner's reports suggest that immediate mortality from LVI may be underestimated. Furthermore, on the basis of this analysis, we conclude that the majority of studies report electrical injury outcomes; however, the majority of them do not analyze complications by low vs high voltage and often lack long-term psychological and rehabilitation outcomes after electrical injury indicating that a variety of central aspects are not being evaluated or assessed.

  15. [Burn wounds caused by a hair-dryer]. (United States)

    Paulsen, Ida Felbo; Alsbjørn, Bjarne


    Burn wounds (ambustio) in children are frequent and occur in about 5% of all children and in about half of these before the age of three. The majority of the burn wounds in children occur at home, most frequently in the kitchen or the bathroom. This case describes an accidental ambustio caused by a hair dryer in a 3-month-old baby. Hair-dryers have become widely used in drying soar baby buttoms. Therefore, professionals as well as parents should be better informed about the potential risks of using hair-dryers for this purpose.

  16. Extensive burns caused by the abusive use of photosensitizing agents. (United States)

    Braye, F; Latarjet, J; Foyatier, J L; Comparin, J P; Tranchand, P; Boucaud, C


    Psoralens are photosensitizing agents used in dermatology as reinforcements in psoralen ultraviolet A-range therapy. We report observations of 14 young women hospitalized for severe burns caused by abusive use of psoralens. The burns were of superficial and deep second-degree depth and covered more than 76% of the body surface on average. All patients needed fluid resuscitation. Hospital stay was 11 days on average. Healing was obtained without skin grafting in all cases. Among the six patients who responded to the mailed questionnaire, negative effects are now present in all patients as inflammatory peaks. Two patients have esthetic sequelae such as dyschromia and scars. The misuse of photosensitizing agents poses many problems. These accidents are very expensive. The largeness of the burned surface can involve a fatal prognosis. And finally, one can suspect that a much larger portion of the population regularly uses these products without any serious accident. In this case carcinogenesis can be expected.

  17. Injury incidence and cause in elite gymnasts. (United States)

    Felländer-Tsai, L; Wredmark, T


    This report describes the incidence, localization, and cause of injuries in Swedish male and female elite gymnasts during 18 active months (three seasons). Thirty-one elite gymnast clubs with all together 437 gymnasts were included in the study, which consisted of a written questionnaire reporting morphometric facts as well as data concerning the injury. There were in total 82 injury reports. The injury incidence was 6.25 per 100 elite gymnasts and season. A majority of the injuries occurred in the lower extremities. The right leg was injured more often than the left. Most of the severe injuries occurred during mounting and dismounting which advocates the need for preventive measures in association with these particular events. Male gymnasts were more prone to sustain severer injuries such as dislocations and fractures. Severe injuries affected the upper extremity in 83%, and the right side was injured more often than the left.

  18. Factors related to child maltreatment in children presenting with burn injuries. (United States)

    Wibbenmeyer, Lucy; Liao, Junlin; Heard, Jason; Kealey, Lyn; Kealey, Gerald; Oral, Resmiye


    The underpinnings of maltreatment in children presenting with burn injuries are necessary to discern as detection and prevention rest on a clear delineation of factors associated with maltreatment. Inaccurate identification of child victims can result in perpetuation of the maltreatment and its attendant neuropsychological sequela. The authors sought to determine factors associated with maltreatment in children presenting with burn injuries, which would guide the burn team in assessing the likelihood of maltreatment. All consenting children admitted with burn injuries were surveyed regarding their injury mechanism and current sociodemographic status. Suspicious injuries were referred by the burn team to the multidisciplinary review team (MRT). The MRT reported injuries with signs of physical abuse, supervision neglect, neglect of other basic needs, or sexual abuse. These children constituted the cases in our study. Variables related to maltreatment were entered into stepwise logistic regression to identify independent predicting variables. Pmaltreatment. Risk factors related to suspicions of maltreatment included: young age, large burns, tap water injury, immersion lines, delay in care, absence of a two-parent family (unconventional family structure), young parents, inconsistent history, and injury pattern. In this single-center prospective study, the authors identified several factors that, when present in injuries with initial suspicion of maltreatment, should trigger a child maltreatment workup. Burn clinicians have an important role as advocates for children and their families. It is important to continue to further the knowledge of maltreatment detection and prevention among children presenting with burn injuries.

  19. Third-Degree Hindpaw Burn Injury Induced Apoptosis of Lumbar Spinal Cord Ventral Horn Motor Neurons and Sciatic Nerve and Muscle Atrophy in Rats

    Sheng-Hua Wu


    Full Text Available Background. Severe burns result in hypercatabolic state and concomitant muscle atrophy that persists for several months, thereby limiting patient recovery. However, the effects of burns on the corresponding spinal dermatome remain unknown. This study aimed to investigate whether burns induce apoptosis of spinal cord ventral horn motor neurons (VHMNs and consequently cause skeletal muscle wasting. Methods. Third-degree hindpaw burn injury with 1% total body surface area (TBSA rats were euthanized 4 and 8 weeks after burn injury. The apoptosis profiles in the ventral horns of the lumbar spinal cords, sciatic nerves, and gastrocnemius muscles were examined. The Schwann cells in the sciatic nerve were marked with S100. The gastrocnemius muscles were harvested to measure the denervation atrophy. Result. The VHMNs apoptosis in the spinal cord was observed after inducing third-degree burns in the hindpaw. The S100 and TUNEL double-positive cells in the sciatic nerve increased significantly after the burn injury. Gastrocnemius muscle apoptosis and denervation atrophy area increased significantly after the burn injury. Conclusion. Local hindpaw burn induces apoptosis in VHMNs and Schwann cells in sciatic nerve, which causes corresponding gastrocnemius muscle denervation atrophy. Our results provided an animal model to evaluate burn-induced muscle wasting, and elucidate the underlying mechanisms.

  20. Brain hemorrhage after electrical burn injury: Case report and probable mechanism (United States)

    Axayacalt, Gutierrez Aceves Guillermo; Alejandro, Ceja Espinosa; Marcos, Rios Alanis; Inocencio, Ruiz Flores Milton; Alfredo, Herrera Gonzalez Jose


    Background: High-voltage electric injury may induce lesion in different organs. In addition to the local tissue damage, electrical injuries may lead to neurological deficits, musculoskeletal damage, and cardiovascular injury. Severe vascular damage may occur making the blood vessels involved prone to thrombosis and spontaneous rupture. Case Description: Here, we present the case of a 39-year-old male who suffered an electrical burn with high tension wire causing intracranial bleeding. He presented with an electrical burn in the parietal area (entry zone) and the left forearm (exit zone). The head tomography scan revealed an intraparenchimatous bleeding in the left parietal area. In this case, the electric way was the scalp, cranial bone, blood vessels and brain, upper limb muscle, and skin. The damage was different according to the dielectric property in each tissue. The injury was in the scalp, cerebral blood vessel, skeletal muscle, and upper limb skin. The main damage was in brain’s blood vessels because of the dielectric and geometric features that lead to bleeding, high temperature, and gas delivering. Conclusion: This is a report of a patient with an electric brain injury that can be useful to elucidate the behavior of the high voltage electrical current flow into the nervous system.

  1. Burn injury during long-term oxygen therapy in Denmark and Sweden: the potential role of smoking (United States)

    Tanash, Hanan A; Ringbaek, Thomas; Huss, Fredrik; Ekström, Magnus


    Background Long-term oxygen therapy (LTOT) increases life expectancy in patients with COPD and severe hypoxemia. Smoking is the main cause of burn injury during LTOT. Policy regarding smoking while on LTOT varies between countries. In this study, we compare the incidence of burn injury that required contact with a health care specialist, between Sweden (a country with a strict policy regarding smoking while on LTOT) and Denmark (a country with less strict smoking policy). Methods This was a population-based, cohort study of patients initiating LTOT due to any cause in Sweden and Denmark. Data on diagnoses, external causes, and procedures were obtained from the Swedish and Danish National Patient Registers for inpatient and outpatient care. Patients were followed from January 1, 2000, until the first of the following: LTOT withdrawal, death, or study end (December 31, 2009). The primary end point was burn injury during LTOT. Results A total of 23,741 patients received LTOT in Denmark and 7,754 patients in Sweden. Most patients started LTOT due to COPD, both in Sweden (74%) and in Denmark (62%). The rate of burn injury while on LTOT was higher in Denmark than in Sweden; 170 (95% confidence interval [CI], 126–225) vs 85 (95% CI, 44–148) per 100,000 person-years; rate ratio 2.0 (95% CI, 1.0–4.1). The risk remained higher after adjustment for gender, age, and diagnosis in multivariate Cox regression, hazard ratio 1.8 (95% CI, 1.0−3.5). Thirty-day mortality after burn injury was 8% in both countries. Conclusion Compared to Sweden, the rate of burn injury was twice as high in Denmark where smoking is not a contraindication for prescribing LTOT. PMID:28123292

  2. Hot asphalt burns: a review of injuries and management options. (United States)

    Bosse, George M; Wadia, Shernaz A; Padmanabhan, Pradeep


    Hot asphalt burns to human tissue can increase the likelihood of infection and potential conversion of partial thickness to full-thickness injuries. Successful intervention for hot asphalt burns requires immediate and effective cooling of the asphalt on the tissue followed by subsequent gradual removal of the cooled asphalt. A review of the literature reveals that multiple substances have been used to remove asphalt, including topical antibiotics, petroleum jelly, a commercial product known as De-Solv-It (ORANGE-SOL, Chandler, AZ), sunflower oil, baby oil, liquid paraffin, butter, mayonnaise, and moist-exposed burn ointment (MEBO). Although many of these products may be effective in the removal of asphalt, they may not be readily available in an emergency department setting. Topical antibiotics are readily available, are more commonly described in the medical literature, and would be expected to be effective in the removal of asphalt. We developed guidelines for on scene (first-aid) management and the initial care of such patients upon presentation to a health care facility. These guidelines emphasize the principles of early cooling, gradual removal of adherent asphalt using topical antibiotics, and avoidance of the use of topical agents, which are likely to result in tissue toxicity.

  3. Thoracic Duct Chylous Fistula Following Severe Electric Injury Combined with Sulfuric Acid Burns: A Case Report (United States)

    Chang, Fei; Cheng, Dasheng; Qian, Mingyuan; Lu, Wei; Li, Huatao; Tang, Hongtai; Xia, Zhaofan


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

  4. The interaction between burn injury and vitamin D metabolism and consequences for the patient. (United States)

    Klein, Gordon L


    The stress and inflammatory responses to burn injury are associated with bone loss. The stress response entails production of large amounts of endogenous glucocorticoids that decrease osteoblasts on the mineralization surface of bone and decreases differentiation of marrow stromal cells into osteoblasts, thereby decreasing the amount of bone formation. Deficiency of osteoblasts also blocks osteoclastogenesis thus leading to low bone turnover and bone loss. The inflammatory response generates cytokines such as interleukin 1-beta and interleukin-6, which normally increase osteoclastogenic bone resorption via stimulation of osteoblast production of RANK ligand. However, in the absence of osteoblasts as a target we postulate that they attack the parathyroid gland chief cells and up-regulate the calcium-sensing receptor. The consequence of this upregulation is the lowering of the circulating calcium necessary to suppress parathyroid hormone production and the development of hypocalcemia and urinary calcium wasting. It is the parathyroid hormone suppression that causes us to postulate acute deficiency of 1,25-dihydroxyvitamin D and the consequence of this for post-burn metabolism could include derepression of the gene that controls renin production, leading to elevated levels of angiotensin II, which can contribute to insulin resistance, as can vitamin D deficiency itself. Moreover, the skin from burned patients cannot synthesize vitamin D normally. Thus vitamin D supplementation is the only means by which to ensure vitamin D sufficiency for burn victims. The proper requirement for vitamin D in acutely burned patients remains unknown.

  5. The effects and mechanisms of insulin on systemic inflammatory response and immune cells in severe trauma, burn injury, and sepsis. (United States)

    Deng, Hu-Ping; Chai, Jia-Ke


    Insulin resistance, hyperglycemia, inflammatory disorders and immune dysfunction cause high morbidity and mortality in patients with severe trauma, burn injuries, or sepsis. Many studies have shown that intensive insulin therapy can combat insulin resistance, decrease blood glucose levels, and induce anabolic processes, thus, decreasing morbidity and mortality. Moreover, in recent years, it has been proven that insulin can attenuate systemic inflammatory responses and modulate the proliferation, apoptosis, differentiation and immune functions of certain immune cells, especially monocytes/macrophages, neutrophils, and T cells associated with severe trauma, burn injury, or sepsis. This effect of insulin may expand our understanding of intensive insulin therapy in critically ill patients. This review attempts to summarize studies on the modulatory effects and mechanisms of insulin therapy on systemic inflammation and immune cells in severe trauma, burn injury and sepsis, and further propose some questions for future studies.

  7. Management of burn injuries – recent developments in resuscitation, infection control and outcomes research

    Directory of Open Access Journals (Sweden)

    Dries David J


    Full Text Available Abstract Introduction Burn injury and its subsequent multisystem effects are commonly encountered by acute care practitioners. Resuscitation is the major component of initial burn care and must be managed to restore and preserve remote organ function. Later complications of burn injury are dominated by infection. Burn centers are often called to manage soft tissue problems outside thermal injury including soft tissue infection and Toxic Epidermal Necrolysis. Methods A selected review of recent reports published by the American Burn Association is provided. Results The burn-injured patient is easily and frequently over resuscitated with complications including delayed wound healing and respiratory compromise. A feedback protocol is designed to limit the occurrence of excessive resuscitation has been proposed but no new "gold standard" for resuscitation has replaced the Parkland formula. Significant additional work has been included in recent guidelines identifying specific infectious complications and criteria for these diagnoses in the burn-injured patient. While new medical therapies have been proposed for patients sustaining inhalation injury, a new standard of medical therapy has not emerged. Renal failure as a contributor to adverse outcome in burns has been reinforced by recent data generated in Scandinavia. Of special problems addressed in burn centers, soft tissue infections and Toxic Epidermal Necrolysis have been reviewed but new treatment strategies have not been identified. The value of burn centers in management of burns and other soft tissue problems is supported in several recent reports. Conclusion Recent reports emphasize the dangers of over resuscitation in the setting of burn injury. No new medical therapy for inhalation injury exists but new standards for description of burn-related infections have been presented. The value of the burn center in care of soft tissue problems including Toxic Epidermal Necrolysis and soft tissue

  8. Decreased pulmonary inflammation after ethanol exposure and burn injury in intercellular adhesion molecule-1 knockout mice. (United States)

    Bird, Melanie D; Morgan, Michelle O; Ramirez, Luis; Yong, Sherri; Kovacs, Elizabeth J


    Clinical and laboratory evidence suggests that alcohol consumption dysregulates immune function. Burn patients who consume alcohol before their injuries demonstrate higher rates of morbidity and mortality, including acute respiratory distress syndrome, than patients without alcohol at the time of injury. Our laboratory observed higher levels of proinflammatory cytokines and leukocyte infiltration in the lungs of mice after ethanol exposure and burn injury than with either insult alone. To understand the mechanism of the increased pulmonary inflammatory response in mice treated with ethanol and burn injury, we investigated the role of intercellular adhesion molecule (ICAM)-1. Wild-type and ICAM-1 knockout (KO) mice were treated with vehicle or ethanol and subsequently given a sham or burn injury. Twenty-four hours postinjury, lungs were harvested and analyzed for indices of inflammation. Higher numbers of neutrophils were observed in the lungs of wild-type mice after burn and burn with ethanol treatment. This increase in pulmonary inflammatory cell accumulation was significantly lower in the KO mice. In addition, levels of KC, interleukin-1beta, and interleukin-6 in the lung were decreased in the ICAM-1 KO mice after ethanol exposure and burn injury. Interestingly, no differences were observed in serum or lung tissue content of soluble ICAM-1 24 hours postinjury. These data suggest that upregulation of adhesion molecules such as ICAM-1 on the vascular endothelium may play a critical role in the excessive inflammation seen after ethanol exposure and burn injury.

  12. Lightning discharges and discharges from overhead power lines with human burn injuries as consequences

    Directory of Open Access Journals (Sweden)

    Javor Sanja


    Full Text Available Discharges from overhead power lines and lightning discharges may severely endanger human life and health. If non-lethal, burn injuries may also last for a lifetime, so as Lichtenberg figures caused by lightning discharges. Some accidents with burns are discussed in this paper and recommendations given for safety reasons. Specific energy transferred by typical lightning strokes currents given in the standard IEC 62305 is calculated. The aim of the paper is to suggest a simple expression for the estimation of safe approach distances to overhead lines, especially if high temperatures and changes in terrain reduced the secure height above ground, or if carrying elevated objects. Results of these calculations are compared to safe approach distances given in regulations of different countries. Safe distances from railway power lines are also considered.

  13. The biochemistry of blister fluid from pediatric burn injuries: proteomics and metabolomics aspects. (United States)

    Zang, Tuo; Broszczak, Daniel A; Broadbent, James A; Cuttle, Leila; Lu, Haitao; Parker, Tony J


    Burn injury is a prevalent and traumatic event for pediatric patients. At present, the diagnosis of burn injury severity is subjective and lacks a clinically relevant quantitative measure. This is due in part to a lack of knowledge surrounding the biochemistry of burn injuries and that of blister fluid. A more complete understanding of the blister fluid biochemistry may open new avenues for diagnostic and prognostic development. Burn insult induces a highly complex network of signaling processes and numerous changes within various biochemical systems, which can ultimately be examined using proteome and metabolome measurements. This review reports on the current understanding of burn wound biochemistry and outlines a technical approach for 'omics' profiling of blister fluid from burn wounds of differing severity.

    This prospective study aims to address mortality in the context of the early pulmonary immune response to burn and inhalation injury. The authors collected bronchoalveolar lavage fluid from 60 burn patients within 14 hours of their injury when smoke inhalation was suspected. Clinical and laboratory parameters and immune mediator profiles were compared with patient outcomes. Patients who succumbed to their injuries were older (P = .005), had a larger % TBSA burn (P burn on mortality, nonsurvivors also had reduced levels of IL-2, IL-4, granulocyte colony-stimulating factor, interferon-γ, macrophage inflammatory protein-1β, and tumor necrosis factor-α (P response to burn and smoke inhalation may be attenuated in patients who succumb to their injuries.

  15. Combination of Radiation and Burn Injury Alters FDG Uptake in Mice (United States)

    Carter, Edward A.; Winter, David; Tolman, Crystal; Paul, Kasie; Hamrahi, Victoria; Tompkins, Ronald; Fischman, Alan J.


    Radiation exposure and burn injury have both been shown to alter glucose utilization in vivo. The present study was designed to study the effect of burn injury combined with radiation exposure, on glucose metabolism in mice using [18F] Fluorodeoxyglucose (18FDG). Groups of male mice weighing approximately 30g were studied. Group 1 was irradiated with a 137Cs source (9 Gy). Group 2 received full thickness burn injury on 25% total body surface area followed by resuscitated with saline (2mL, IP). Group 3 received radiation followed 10 minutes later by burn injury. Group 4 were sham treated controls. After treatment, the mice were fasted for 23 hours and then injected (IV) with 50 µCi of 18FDG. One hour post injection, the mice were sacrificed and biodistribution was measured. Positive blood cultures were observed in all groups of animals compared to the shams. Increased mortality was observed after 6 days in the burn plus radiated group as compared to the other groups. Radiation and burn treatments separately or in combination produced major changes in 18FDG uptake by many tissues. In the heart, brown adipose tissue (BAT) and spleen, radiation plus burn produced a much greater increase (p<0.0001) in 18FDG accumulation than either treatment separately. All three treatments produced moderate decreases in 18FDG accumulation (p<0.01) in the brain and gonads. Burn injury, but not irradiation, increased 18FDG accumulation in skeletal muscle; however the combination of burn plus radiation decreased 18FDG accumulation in skeletal muscle. This model may be useful for understanding the effects of burns + irradiation injury on glucose metabolism and in developing treatments for victims of injuries produced by the combination of burn plus irradiation.

    Full Text Available In order to prevent anterior cruciate ligament injuries it is necessary to define risk factors and to analyze the most frequent causes of injuries - that being the aim of this study. The study sample consisted of 451 surgically treated patients, including 400 sportsmen (65% of them being active and 35% recreational sportsmen, 29% female and 71% male; of whom 90% were younger than 35. Sports injuries, as the most frequent cause of anterior cruciate ligament injuries, were recorded in 88% of patients (non-contact ones in 78% and contact ones in 22%, injuries occurring in everyday activities in 11% and in traffic in 1%. Among sportsmen, reconstruction of the anterior cruciate ligament was most frequently performed in football players (48%, then in handball players (22%, basketball players (13%, volleyball players (8%, martial arts fighters (4%. However, the injury incidence was the highest among the active basketball players (1 injured among 91 active players. Type of footwear, warming up before the activity, genetic predisposition and everyday therapy did not have a significant influence on getting injured. Anterior cruciate ligament injuries happened three times more often during matches, in the middle and at the end of a match and training session (79%, at landing after the jump or when changing direction of movement (75% without a contact with other competitors, on dry surfaces (79%, among not so well prepared sportsmen.

    have not been reported earlier. We report the case of a 21-yearold man who suffered full thickness burns by electrical stimulation with electrode implanted on the anterior side of his left thigh. The burn area was treated consevatively within five weeks without any surgery. The burn injuries due to electrotherapy device are preventable and therefore, some basic measures may reduce the incidence of accidental burn injury. We hope that this case report will raise awareness about the dangers involved in the ever-increasing use of electrotherapy devices.

  2. Effect of fasting on the metabolic response of liver to experimental burn injury.

    Directory of Open Access Journals (Sweden)

    Mehmet A Orman

    Full Text Available Liver metabolism is altered after systemic injuries such as burns and trauma. These changes have been elucidated in rat models of experimental burn injury where the liver was isolated and perfused ex vivo. Because these studies were performed in fasted animals to deplete glycogen stores, thus simplifying quantification of gluconeogenesis, these observations reflect the combined impact of fasting and injury on liver metabolism. Herein we asked whether the metabolic response to experimental burn injury is different in fed vs. fasted animals. Rats were subjected to a cutaneous burn covering 20% of the total body surface area, or to similar procedures without administering the burn, hence a sham-burn. Half of the animals in the burn and sham-burn groups were fasted starting on postburn day 3, and the others allowed to continue ad libitum. On postburn day 4, livers were isolated and perfused for 1 hour in physiological medium supplemented with 10% hematocrit red blood cells. The uptake/release rates of major carbon and nitrogen sources, oxygen, and carbon dioxide were measured during the perfusion and the data fed into a mass balance model to estimate intracellular fluxes. The data show that in fed animals, injury increased glucose output mainly from glycogen breakdown and minimally impacted amino acid metabolism. In fasted animals, injury did not increase glucose output but increased urea production and the uptake of several amino acids, namely glutamine, arginine, glycine, and methionine. Furthermore, sham-burn animals responded to fasting by triggering gluconeogenesis from lactate; however, in burned animals the preferred gluconeogenic substrate was amino acids. Taken together, these results suggest that the fed state prevents the burn-induced increase in hepatic amino acid utilization for gluconeogenesis. The role of glycogen stores and means to increase and/or maintain internal sources of glucose to prevent increased hepatic amino acid

  5. Pulmonary inflammation after ethanol exposure and burn injury is attenuated in the absence of IL-6. (United States)

    Chen, Michael M; Bird, Melanie D; Zahs, Anita; Deburghgraeve, Cory; Posnik, Bartlomiej; Davis, Christopher S; Kovacs, Elizabeth J


    Alcohol consumption leads to an exaggerated inflammatory response after burn injury. Elevated levels of interleukin-6 (IL-6) in patients are associated with increased morbidity and mortality after injury, and high systemic and pulmonary levels of IL-6 have been observed after the combined insult of ethanol exposure and burn injury. To further investigate the role of IL-6 in the pulmonary inflammatory response, we examined leukocyte infiltration and cytokine and chemokine production in the lungs of wild-type and IL-6 knockout mice given vehicle or ethanol (1.11 g/kg) and subjected to a sham or 15% total body surface area burn injury. Levels of neutrophil infiltration and neutrophil chemoattractants were increased to a similar extent in wild-type and IL-6 knockout mice 24 h after burn injury. When ethanol exposure preceded the burn injury, however, a further increase of these inflammatory markers was seen only in the wild-type mice. Additionally, signal transducer and activator of transcription-3 (STAT3) phosphorylation did not increase in response to ethanol exposure in the IL-6 knockout mice, in contrast to their wild-type counterparts. Visual and imaging analysis of alveolar wall thickness supported these findings and similar results were obtained by blocking IL-6 with antibody. Taken together, our data suggest a causal relationship between IL-6 and the excessive pulmonary inflammation observed after the combined insult of ethanol and burn injury.

    Oxidative stress has an important role in the development of multiorgan failure after major burn. This study was designed to determine the possible protective effect of experimental hypothyroidism in hepatic and gastrointestinal injury induced by thermal trauma. Sprague Dawley rats were administered saline or PTU (10 mgkg(-1) i.p.) for 15 days, and hypothyroidism was confirmed by depressed serum T(3) and T(4) concentrations. Under brief ether anesthesia, shaved dorsum of rats was exposed to 90 degrees C (burn group) or 25 degrees C (control group) water bath for 10s. PTU or saline treatment was repeated at the 12th hour of the burn. Rats were decapitated 24h after injury and tissue samples from liver, stomach and ileum were taken for the determination of malondialdehyde (MDA) and glutathione (GSH) levels, myeloperoxidase (MPO) activity and collagen contents. Formation of reactive oxygen species in tissue samples was monitored by using chemiluminescence (CL) technique with luminol and lucigenin probes. Tissues were also examined microscopically. Tumor necrosis factor (TNF)-alpha and lactate dehydrogenase (LDH) were assayed in serum samples. Severe skin scald injury (30% of total body surface area) caused a significant decrease in GSH level, which was accompanied with significant increases in MDA level, MPO activity, CL levels and collagen content of the studied tissues (pPTU treatment reversed all these biochemical indices, as well as histopathological alterations induced by thermal trauma. Our results suggest that PTU-induced hypothyroidism reduces oxidative damage in the hepatic, gastric and ileal tissues probably due to hypometabolism, which is associated with decreased production of reactive oxygen metabolites and enhancement of antioxidant mechanisms.

  7. Burn Rehabilitation

    Koray Aydemir


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

Despite warnings about potential dangers, a considerable number of patients continue to smoke while on LTOT. The incidence of burn injuries related to LTOT is unknown. The aim of this study was to estimate the rate of burn injury requiring health care contact during LTOT.Methods: Prospective, population-based, consecutive cohort study of people starting LTOT from any cause between January 1, 1992 and December 31, 2009 in the Swedish National Register of Respiratory Failure (Swedevox.Results: In total, 12,497 patients (53% women were included. The mean (standard deviation age was 72±9 years. The main reasons for starting LTOT were chronic obstructive pulmonary disease (75% and pulmonary fibrosis (15%. Only 269 (2% were active smokers when LTOT was initiated. The median follow-up time to event was 1.5 years (interquartile range, 0.55–3.1. In total, 17 patients had a diagnosed burn injury during 27,890 person-years of LTOT. The rate of burn injury was 61 (95% confidence interval, 36–98 per 100,000 person-years. There was no statistically significant difference in the rate of burn injury between ever-smokers and never-smokers, or between men and women.Conclusion: The rate of burn injuries in patients on LTOT seems to be low in Sweden. The strict requirements in Sweden for smoking cessation before LTOT initiation may contribute to this finding.Keywords: respiratory failure, oxygen, fire

    After scald burn-injury, the intestinal immune system responds to maintain immune balance. In this regard CD4+T cells in Gut-Associated Lymphoid Tissues (GALT), like mesenteric lymph nodes (MLN) and Peyer's patches (PP) respond to avoid immune suppression following major injury such as burn. Therefore, we hypothesized that the gut CD4+T cells become dysfunctional and turn the immune homeostasis towards depression of CD4+ T cell-mediated adaptive immune responses.

  13. Cardiovascular Dysfunction Following Burn Injury: What We Have Learned from Rat and Mouse Models

    Directory of Open Access Journals (Sweden)

    Ashley N. Guillory


    Full Text Available Severe burn profoundly affects organs both proximal and distal to the actual burn site. Cardiovascular dysfunction is a well-documented phenomenon that increases morbidity and mortality following a massive thermal trauma. Beginning immediately post-burn, during the ebb phase, cardiac function is severely depressed. By 48 h post-injury, cardiac function rebounds and the post-burn myocardium becomes tachycardic and hyperinflammatory. While current clinical trials are investigating a variety of drugs targeted at reducing aspects of the post-burn hypermetabolic response such as heart rate and cardiac work, there is still a paucity of knowledge regarding the underlying mechanisms that induce cardiac dysfunction in the severely burned. There are many animal models of burn injury, from rodents, to sheep or swine, but the majority of burn related cardiovascular investigations have occurred in rat and mouse models. This literature review consolidates the data supporting the prevalent role that β-adrenergic receptors play in mediating post-burn cardiac dysfunction and the idea that pharmacological modulation of this receptor family is a viable therapeutic target for resolving burn-induced cardiac deficits.

  14. Neuronal Plasticity Associated with Burn Injury and Its Relevance for Perception and Management of Pain in Burn Patients

    Directory of Open Access Journals (Sweden)

    Terence J Coderre


    Full Text Available Through the introduction of the gate control theory and various subsequent works, Ronald Melzack has inspired many investigators worldwide to realize two important facts about pain. First, incoming pain messages are subject to both negative and positive modulation, which significantly affect its perception. Second, the progression of knowledge about the basic mechanisms underlying persistent and chronic pain is critically dependent on the increased understanding of the complexity of the symptoms experienced by pain patients. The present paper examines these two very important issues in an effort to understand better the mechanisms that underlie the pain suffered by burn patients. The physiological responses to burn injury involve many different mediators and mechanisms, all of which contribute to pain perception and development of neuronal plasticity underlying short and long term changes in pain sensitivity. While experimental burn injuries in humans and animals are typically well controlled and mild, in burn victims, the severity is much more variable, and clinical care involves repeated traumas and manipulations of the injured sites. Recurrent inputs from damaged and redamaged tissue impinge on a nervous system that becomes an active participant in the initiation of changes in sensory perception and maintenance of long term sensory disturbances. Recently acquired experimental evidence on postburn hyperalgesia, central hyperexcitability and changes in opioid sensitivity provides strong support that burn patients need an analgesic approach aimed at preventing or reducing the 'neural' memory of pain, including the use of more than one treatment modality. Burn injuries offer a unique opportunity to combine experimental and clinical research to understand pain mechanisms better. Over the years, Ronald Melzack has insisted that one of the most laudable enterprises in research is to span the gap between these two often separate worlds.

  15. Sodium butyrate protects against severe burn-induced remote acute lung injury in rats.

    Directory of Open Access Journals (Sweden)

    Xun Liang

    Full Text Available High-mobility group box 1 protein (HMGB1, a ubiquitous nuclear protein, drives proinflammatory responses when released extracellularly. It plays a key role as a distal mediator in the development of acute lung injury (ALI. Sodium butyrate, an inhibitor of histone deacetylase, has been demonstrated to inhibit HMGB1 expression. This study investigates the effect of sodium butyrate on burn-induced lung injury. Sprague-Dawley rats were divided into three groups: 1 sham group, sham burn treatment; 2 burn group, third-degree burns over 30% total body surface area (TBSA with lactated Ringer's solution for resuscitation; 3 burn plus sodium butyrate group, third-degree burns over 30% TBSA with lactated Ringer's solution containing sodium butyrate for resuscitation. The burned animals were sacrificed at 12, 24, and 48 h after burn injury. Lung injury was assessed in terms of histologic changes and wet weight to dry weight (W/D ratio. Tumor necrosis factor (TNF-α and interleukin (IL-8 protein concentrations in bronchoalveolar lavage fluid (BALF and serum were measured by enzyme-linked immunosorbent assay, and HMGB1 expression in the lung was determined by Western blot analysis. Pulmonary myeloperoxidase (MPO activity and malondialdehyde (MDA concentration were measured to reflect neutrophil infiltration and oxidative stress in the lung, respectively. As a result, sodium butyrate significantly inhibited the HMGB1 expressions in the lungs, reduced the lung W/D ratio, and improved the pulmonary histologic changes induced by burn trauma. Furthermore, sodium butyrate administration decreased the TNF-α and IL-8 concentrations in BALF and serum, suppressed MPO activity, and reduced the MDA content in the lungs after severe burn. These results suggest that sodium butyrate attenuates inflammatory responses, neutrophil infiltration, and oxidative stress in the lungs, and protects against remote ALI induced by severe burn, which is associated with inhibiting HMGB1

    This study was to re-evaluate inhalation injury as a prognostic factor in burn patients and to determine the factors that should be considered when refining the definition of inhalation injury. A total of 192 burn patients (152 men, 40 women; mean age, 46.1±13.8 years) who were suspected to have an inhalation injury and underwent bronchoscopy between January 2010 and June 2012 were included in this prospective observational study. All patients underwent bronchoscopy within 24h of sustaining the burn. The bronchoscopic findings were classified as normal, mild, moderate, and severe. Mechanical ventilation was administered, when required. Age, percentage of TBSA burned, ABSI score, requirement of mechanical ventilation and PF ratio, but not inhalation injury, COHb level, and bronchoscopic grades, significantly differed between the survivors and non-survivors (pburns. Other components such as severity of inhalation injury determined using bronchoscopy, and administration of mechanical ventilation might help predict the morbidity and mortality of burn patients with inhalation injury and all of the factors should be considered when the definition of inhalation injury is refined.

  18. Thermal Injury Model in the Rabbit Ear with Quantifiable Burn Progression and Hypertrophic Scar. (United States)

    Friedrich, Emily E; Niknam-Bienia, Solmaz; Xie, Ping; Jia, Sheng-Xian; Hong, Seok Jong; Mustoe, Thomas A; Galiano, Robert D


    Hypertrophic scar is a major clinical outcome of deep-partial thickness to full thickness thermal burn injury. Appropriate animal models are a limitation to burn research due to the lack of, or access to, animal models which address the endpoint of hypertrophic scar. Lower species, such as rodents, heal mainly by contracture, which limits the duration of study. Higher species, such as pigs, heal more similarly to humans, but are associated with high cost, long duration for scar development, challenges in quantifying scar hypertrophy, and poor manageability. Here we present a quantifiable deep-partial thickness burn model in the rabbit ear. Burns were created using a dry-heated brass rod for 10 s and 20 s at 90°C. At the time of eschar excision on day 3, excisional wounds were made on the contralateral ear for comparison. Burn wound progression, in which the wound size expands over time is a major distinction between excisional and thermal injuries, was quantified at 1 h and 3 d after the injuries using calibrated photographs and histology and the size of the wounds was found to be unchanged from the initial wound size at 1 h, but 10% in the 20 s burn wounds at 3 d. A quantifiable hypertrophic scar, measured by histology as the scar elevation index, was present in both 20 s burn wounds and excisional wounds at day 35. ImageJ measurements revealed that the 20 s burn wound scars were 22% larger than the excisional wound scars and the 20 s burn scar area measurements from histology were 26% greater than in the excisional wound scar. The ability to measure both burn progression and scar hypertrophy over a 35-day time frame suits this model to screening early intervention burn wound therapeutics or scar treatments in a burn-specific scar model.

    Boschini, Laura P; Tyson, Anna F; Samuel, Jonathan C; Kendig, Claire E; Mjuweni, Stephano; Varela, Carlos; Cairns, Bruce A; Charles, Anthony G


    Patients with epilepsy have higher incidence and severity of burn injury. Few studies describe the association between epilepsy and burns in low-income settings, where epilepsy burden is highest. The authors compared patients with and without seizure disorder in a burn unit in Lilongwe, Malawi. The authors conducted a retrospective study of patients admitted to the Kamuzu Central Hospital burn ward from July 2011 to December 2012. Descriptive analysis of patient characteristics and unadjusted and adjusted analyses of risk factors for mortality were conducted for patients with and without seizure disorder. Prevalence of seizure disorder was 10.7% in the study population. Adults with burns were more likely to have seizure disorder than children. Flame injury was most common in patients with seizure disorder, whereas scalds predominated among patients without seizure disorder. Whereas mortality did not differ between the groups, mean length of stay was longer for patients with seizure disorder, 42.1 days vs 21.6 days. Seizure disorder continues to be a significant risk factor for burn injury in adults in Malawi. Efforts to mitigate epilepsy will likely lead to significant decreases in burns among adults in Sub-Saharan Africa and must be included in an overall burn prevention strategy in our environment.

[Shanxi Maternity and Children' s Hospital, Taiyuan (China)


    Recently a huge amount of fluoride in coal has been released into indoor environments by the combustion of coal and fluoride pollution seems to be increasing in some rural areas in China. Combustion of coal and coal bricks is the primary source of gaseous and aerosol fluoride and these forms of fluoride can easily enter exposed food products and the human respiratory tract. Major human fluoride exposure was caused by consumption of fluoride contaminated food, such as corn, chilies and potatoes. For each diagnostic syndrome of dental fluorosis, a log-normal distribution was observed on the logarithm of urinary fluoride concentration in students in China. Urinary fluoride content was found to be a primary health indicator of the prevalence of dental fluorosis in the community. In the fluorosis areas, osteosclerosis in skeletal fluorosis patients was observed with a high prevalence. A biochemical marker of bone resorption, urinary deoxypyridinoline content was much higher in residents in China than in residents in Japan. It was suggested that bone resorption was stimulated to a greater extent in residents in China and fluoride may stimulate both bone resorption and bone formation. Renal function especially glomerular filtration rate was very sensitive to fluoride exposure. Inorganic phosphate concentrations in urine were significantly lower in the residents in fluorosis areas in China than in non-fluorosis area in China and Japan. Since airborne fluoride from the combustion of coal pollutes extensively both the living environment and food, it is necessary to reduce fluoride pollution caused by coal burning.

  2. Coping with burns: the role of coping self-efficacy in the recovery from traumatic stress following burn injuries. (United States)

    Bosmans, Mark W G; Hofland, Helma W; De Jong, Alette E; Van Loey, Nancy E


    We conducted a three-wave prospective study among patients with burns (N = 178) to examine the prospective influence of coping self-efficacy (CSE) perceptions on trajectories of posttraumatic stress symptoms in the first 12 months after burn injuries. Using linear growth curve modeling, we corrected for demographics, the number of surgeries during initial admittance, trait coping styles, and changing levels of health-related quality of life. CSE during initial admission was by far the strongest predictor of both initial PTSD symptoms and degree of symptom change with higher CSE levels associated with lower initial symptoms and a steeper decline of symptoms over time. Of the other variables only avoidant coping was associated with higher initial symptom levels, and only emotional expression associated with greater rate of recovery. Current findings suggest that CSE plays a pivotal role in recovery from posttraumatic stress after a burn injury, even when the role of burn-related impairments is taken into consideration. Implications of findings are discussed.

    Caliskan, Mustafa; Turk, Emin; Karagulle, Erdal; Ciftci, Ozgur; Oguz, Hakan; Kostek, Osman; Moray, Gokhan; Haberal, Mehmet


    The authors sought to evaluate coronary microvascular function and left ventricular diastolic dysfunction using transthoracic Doppler echocardiography in burn patients. In this study, 32 adult burn patients with partial or full-thickness scald burns that were hospitalized and treated were included. The control group was matched for age and sex and was composed of otherwise healthy volunteers. Transthoracic Doppler echocardiography examinations and simultaneous laboratory tests for cardiac evaluation were performed on the sixth month after burn injury as well as with the control group. High-sensitivity C-reactive protein levels were significantly higher in the burn patients than in controls (5.17 ± 3.86 vs 2.42 ± 1.78; P = .001). Lateral isovolumic relaxation time was significantly higher in the burn injury group than in the control group (92.7 ± 15.7 vs 85.5 ± 8.3; P = .03). Baseline coronary diastolic peak flow velocity of the left anterior descending artery was similar in both groups. However, hyperemic diastolic peak flow velocity and coronary flow velocity reserve (2.26 ± 0.48 vs 2.94 ± 0.47; P < .001) were significantly lower in the burn injury group than in the control group. Coronary flow velocity reserve was significantly and inversely correlated with high-sensitivity C-reactive protein, burn ratio, creatinine, and mitral A-wave max velocity. At the sixth month of treatment, burn patients had high-sensitivity C-reactive protein levels during this period, suggesting that inflammation still exists. In addition, subclinical coronary microvascular and left ventricular diastolic dysfunction can occur in burn patients without traditional cardiovascular risk factors. However, these results must be supported by additional studies.

  5. Financial burden of burn injuries in iran: a report from the burn registry program. (United States)

    Karimi, H; Motevalian, S A; Momeni, M; Ghadarjani, M


    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. Patients who contracted infections endured longer hospital stays, meaning increased costs of US$ 195 per day. With comparable outcome and results, the cost of burn treatment in Iran is cheaper than in the US and Europe.

  6. Identifying and Understanding the Health Information Experiences and Preferences of Individuals With TBI, SCI, and Burn Injuries

    Directory of Open Access Journals (Sweden)

    Nathan T Coffey MPH


    Full Text Available Introduction: Traumatic brain injury, spinal cord injury, and burn injury can cause lifelong disability and changes in quality of life. In order to meet the challenges of postinjury life, various types of health information are needed. We sought to identify preferred sources of health information and services for persons with these injuries and discover how accessibility could be improved. Methods: Thirty-three persons with injury participated in semistructured interviews. Responses to interview questions were coded using NVivo. Results: Participants’ difficulties accessing health information varied by injury type and individually. The majority of respondents found information via the Internet and advocated its use when asked to describe their ideal health information system. Nearly all participants supported the development of a comprehensive care website. When searching for health information, participants sought doctor and support group networks, long-term health outcomes, and treatments specific to their injury. Conclusion: To optimize the quality of health information resources, Internet-based health-care platforms should add or highlight access points to connect patients to medical professionals and support networks while aggregating specialized, injury-specific research and treatment information.

  8. Cardiac contraction and calcium transport function aftersevere burn injury in rats

    Institute of Scientific and Technical Information of China (English)


    Objective: To examine the function change of myocardial calcium transports and determined what role the change plays in cardiac dysfunction after severe burn injury in rats. Methods: The contraction and relaxation properties of the left ventricle (LV) were studied in the isolated hearts preparations of Wistar rats at 3, 8, and 24 h after a 30%TBSA (total body surface area) full-thickness burn. The calcium transport function of the sarcoplasmic reticulum (SR) was measured by the millipore filtration technique. Results: The maximal rate of LV pressure (± dp/dtmax) of the burn group was significantly lower than that of the control group (P < 0.01). In addition, the calciumdependent ATPase activity and the coupling ratio of SR were also markedly depressed. Conclusions: It indicates that the decrease in the SR calcium transport function is one of the important mechanisms for the cardiac contractile dysfunction after severe burn injury.

  9. Does organophosphate poisoning cause cardiac injury? (United States)

    Aghabiklooei, Abbas; Mostafazadeh, Babak; Farzaneh, Esmaeil; Morteza, Afsaneh


    Organophosphates are insecticides which are widely used as a suicidal agent in Iran. They are associated with different types of cardiac complications including cardiac arrest and arrhythmia, however their role in cardiac injury is not known yet. The aim of this study was to investigate the presence of myocardial damage in patients with cholinesterase poisoning.It was a prospective study conducted from January 2008 to March 2010. Cohorts of patients with cholinesterase poisoning due to suicidal attempt who have been referred to Loghman hospital were selected. Patients who have taken more than one poison or were used concomitant drugs were excluded. Physical examination was performed on admission to discover warning sign. Peripheral arterial blood gases, creatine kinase, creatine kinase-myocardial band, troponin-T measurements were performed in all cases. There were 24 patients, 7 of them women, with the mean age of 41.2±15.05 who were included in this study. Non-survivors had significantly higher levels of systolic blood pressure, partial pressure of oxygen in arterial blood, partial pressure of carbon dioxide, bicarbonate Glasgow Coma Scale scoring and longer duration of mechanical ventilation. Our findings showed that cardiac injury is an important cause of death in organophosphate poisoning. It could be hypothesized that cardiac injury is a strong predictor of death in patients with organophosphate poisoning.

  11. The treatment of posttraumatic stress disorder and related psychosocial consequences of burn injury: a pilot study. (United States)

    Cukor, Judith; Wyka, Katarzyna; Leahy, Nicole; Yurt, Roger; Difede, JoAnn


    Burn injuries are unique in their medical and psychological impact, yet there has been little exploration of psychiatric treatment for this population. This uncontrolled pilot study assessed feasibility, acceptability, and preliminary efficacy of a treatment protocol designed to address posttraumatic stress disorder, depression, coping with scarring, and community integration among adult burn survivors. A 14-session, manualized treatment protocol was created using cognitive-behavioral interventions including imaginal exposure, behavioral activation, cognitive restructuring, modeling, and in vivo exposure. Responses were measured using the Clinician Administered PTSD Scale, Beck Depression Index, Community Integration Questionnaire, Oswestry Disability Questionnaire, and Burn Specific Health Scale. Nine of 10 enrolled patients (60% women; mean = 42 years old) completed treatment. Burn size was 0.5% to 65%; mechanism of injury included flame (4), scald (5), and contact (1) burns. Mean acute hospitalization was 30.1 days (range = 13-87); mean time from injury to treatment was 3.2 months (range = 1-7). Baseline mean posttraumatic stress score was 68 on the Clinician Administered PTSD Scale (severe); scores decreased by 36% to a mean of 45.3 at posttreatment, with a large effect size. Baseline self-reported depression was 21 (moderate) on the Beck Depression Index, decreasing by 47% to a mean of 12 posttreatment (nonclinical). Change in community reintegration score was significant and large, and body image showed significant improvement. The protocol showed promise in the treatment of posttraumatic stress disorder, depression, self-image, and community reintegration following burn injury. These findings suggest that coping may improve with treatment and symptoms should not be dismissed as unavoidable consequences of burn injury.

  12. Non-severe burn injury leads to depletion of bone volume that can be ameliorated by inhibiting TNF-α. (United States)

    O'Halloran, Emily; Kular, Jasreen; Xu, Jiake; Wood, Fiona; Fear, Mark


    Bone loss after severe burn injury is well established, and is thought to be a consequence of the severe hyper-metabolic response as well as changes in cytokine and glucocorticoid levels that decrease bone synthesis and increase rate of loss. However, 90% of presentations are for non-severe burns which do not elicit this response. Little is known about whether these non-severe injuries may also affect bone tissue, and whether other mechanisms may be involved. To investigate whether bone loss occurs after a non-severe burn injury we used a mouse model of an approximately 8% total body surface area (TBSA) full-thickness burn and micro-CT. We also assessed whether blocking TNF-α after a burn injury by administration of an antibody could modulate the impacts of the burn on bone tissue. There was a significant loss of trabecular bone volume of (3.27% compared to 5.27%, p=0.0051) after non-severe burn injury. Trabecular number was significantly decreased (0.57/mm after injury compared to 1.02/mm controls, p=0.0051) and spacing increased after burn injury (0.40 compared to 0.28, p=0.0083). Anti-TNF-α antibodies significantly improved trabecular bone volume (8.53%, p=0.0034) and number after burn injury (1.28/mm, p=0.0034). There was no significant change observed in cortical bone after burn injury or administration of anti-TNF-α antibodies. These findings show that non-severe burn injury can lead to changes in bone metabolism. Monitoring bone density in patients with non-severe injuries and interventions to limit the impacts of the inflammatory storm may benefit patient recovery and outcomes.

    Full Text Available INTRODUCTION A major public health problem in India is burns injuries. It is prevalent especially in low and middle income countries, where over 95% of all burn deaths occur. Fire related burns alone account for over 0.3 million deaths per year. But Death is not the only consequence. There are around 80% of the fire victims who become disfigured and permanently disabled. For some this means living with the stigma and rejection that all too often comes with disability and disfigurement.

  14. Analysis of Facial Injuries Caused by Power Tools. (United States)

    Kim, Jiye; Choi, Jin-Hee; Hyun Kim, Oh; Won Kim, Sug


    The number of injuries caused by power tools is steadily increasing as more domestic woodwork is undertaken and more power tools are used recreationally. The injuries caused by the different power tools as a consequence of accidents are an issue, because they can lead to substantial costs for patients and the national insurance system. The increase in hand surgery as a consequence of the use of power tools and its economic impact, and the characteristics of the hand injuries caused by power saws have been described. In recent years, the authors have noticed that, in addition to hand injuries, facial injuries caused by power tools commonly present to the emergency room. This study aimed to review the data in relation to facial injuries caused by power saws that were gathered from patients who visited the trauma center at our hospital over the last 4 years, and to analyze the incidence and epidemiology of the facial injuries caused by power saws. The authors found that facial injuries caused by power tools have risen continually. Facial injuries caused by power tools are accidental, and they cause permanent facial disfigurements and functional disabilities. Accidents are almost inevitable in particular workplaces; however, most facial injuries could be avoided by providing sufficient operator training and by tool operators wearing suitable protective devices. The evaluation of the epidemiology and patterns of facial injuries caused by power tools in this study should provide the information required to reduce the number of accidental injuries.

    目的:观察过氧化甲乙酮( methyl ethyl ketone peroxide, MEKP)烧伤对新西兰大白兔肾功能的影响及肾组织的病理变化,探讨MEKP烧伤致肾损伤的机制。方法将30只新西兰大白兔随机分为普通火焰烧伤组( A组)、MEKP烧伤组( B组)及对照组,每组10只。分别于0、1、2、4 h采集血液,观察3组血清肌酐( Scr)、尿素( BUN)水平的变化情况及肾组织形态学变化。结果3组伤后0 h Scr和BUN比较差异无统计学意义(P>0.05)。伤后1、2、4 h A、B组Scr、BUN均高于对照组,且B组高于A组(P0. 05);at 1, 2 and 4 h after burning, the Scr and BUN levels in group A and B were significantly higher than those in control group, and the levels in group B were higher than those in group A (P<0. 05, P<0. 01). Pathological signs of renal tissues included epithelial cell degeneration and necrosis of kidney tubule ( especially proximal tubule) and structural damage of renal glomerulus in group B. Conclusion The kidney injury mechanisms after MEKP burns are tissue ischemia and hypoxia and reperfusion injury. Meanwhile, methyl ethyl ketone peroxide was absorbed into a large amount of free radicals and organic acids pro-duced by blood metabolism, and it can induce lipid peroxidation of renal tubular epithelial cell and glomerular basal cell membranes, cellular metabolism disorder, which can cause further damage to renal tubular epithelial cell and renal glomer-ulus.

  19. Brown adipose tissue and its modulation by a mitochondria-targeted peptide in rat burn injury-induced hypermetabolism. (United States)

    Yo, Kikuo; Yu, Yong-Ming; Zhao, Gaofeng; Bonab, Ali A; Aikawa, Naoki; Tompkins, Ronald G; Fischman, Alan J


    Hypermetabolism is a prominent feature of burn injury, and altered mitochondria function is presumed to contribute to this state. Recently, brown adipose tissue (BAT) was found to be present not only in rodents but also in humans, and its activity is associated with resting metabolic rate. In this report, we elucidate the relationship between burn injury-induced hypermetabolism and BAT activity and the possible role of the mitochondria-targeted peptide SS31 in attenuating burn injury-induced hypermetabolism by using a rat burn injury model. We demonstrate that burn injury induces morphological changes in interscapular BAT (iBAT). Burn injury was associated with iBAT activation, and this effect was positively correlated with increased energy expenditure. BAT activation was associated with augmentation of mitochondria biogenesis, and UCP1 expression in the isolated iBAT mitochondria. In addition, the mitochondria-targeted peptide SS31 attenuated burn injury-induced hypermetabolism, which was accompanied by suppression of UCP1 expression in isolated mitochondria. Our results suggest that BAT plays an important role in burn injury-induced hypermetabolism through its morphological changes and expression of UCP1.

  3. Inflammatory and protein metabolism signaling responses in human skeletal muscle after burn injury. (United States)

    Merritt, Edward K; Cross, James M; Bamman, Marcas M


    Severe burn injuries lead to a prolonged hypercatabolic state resulting in dramatic loss of skeletal muscle mass. Postburn muscle loss is well documented but the molecular signaling cascade preceding atrophy is not. The purpose of this study is to determine the response to burn injury of signaling pathways driving muscle inflammation and protein metabolism. Muscle biopsies were collected in the early flow phase after burn injury from the vastus lateralis of a noninjured leg in patients with 20 to 60% TBSA burns and compared with uninjured, matched controls. Circulating levels of proinflammatory cytokines were also compared. Immunoblotting was performed to determine the protein levels of key signaling components for translation initiation, proteolysis, and tumor necrosis factor/nuclear factor kappa B (NFκB)and interleukin (IL)-6/STAT3 signaling. Burn subjects had significantly higher levels of circulating proinflammatory cytokines, with no difference in muscle STAT3 activity and lower NFκB activity. No differences were found in any translational signaling components. Regarding proteolytic signaling in burn, calpain-2 was 47% higher, calpastatin tended to be lower, and total ubiquitination was substantially higher. Surprisingly, a systemic proinflammatory response 3 to 10 days postburn did not lead to elevated muscle STAT3 or NFκB signaling. Signaling molecules governing translation initiation were unaffected, whereas indices of calcium-mediated proteolysis and ubiquitin-proteasome activity were upregulated. These novel findings are the first in humans to suggest that the net catabolic effect of burn injury in skeletal muscle (ie, atrophy) may be mediated, at least during the early flow phase, almost entirely by an increased proteolytic activity in the absence of suppressed protein synthesis signaling.

    Diego, Alejandro M; Serghiou, Michael; Padmanabha, Anand; Porro, Laura J; Herndon, David N; Suman, Oscar E


    Exercise programs capable of contributing positively to the long-term rehabilitation of burn patients should be included in outpatient rehabilitation programs. However, the extent and intensity of the resistance and cardiopulmonary exercise prescribed are unclear. This study was conducted to investigate the existence, design, content, and prescription of outpatient cardiopulmonary and resistance exercise programs within outpatient burn rehabilitation. A survey was designed to gather information on existing exercise programs for burn survivors and to assess the extent to which these programs are included in overall outpatient rehabilitation programs. Three hundred and twenty-seven surveys were distributed in the licensed physical and occupational therapists part of the American Burn Association Physical Therapy/Occupational Therapy Special Interest Group. One hundred and three surveys were completed. Eighty-two percent of respondents indicated that their institutions offered outpatient therapy after discharge. The frequency of therapists' contact with patients during this period varied greatly. Interestingly, 81% of therapists stated that no hospital-based cardiopulmonary endurance exercise programs were available. Patients' physical function was infrequently determined through the use of cardiopulmonary parameters (oxygen consumption and heart rate) or muscle strength. Instead, more subjective parameters such as range of motion (75%), manual muscle testing (61%), and quality of life (61%) were used. Prescription and follow-up assessment of cardiopulmonary endurance training are inconsistent among institutions, underscoring the need for greater awareness of the importance of exercise in any burn rehabilitation program. Identification of cardiopulmonary and progressive resistance parameters for establishing and tracking exercise training is also needed to maximize exercise-induced benefits.

  7. Research into the prevention and treatment of burns due to specific causes should be highly strengthened%特殊原因烧伤的防治研究不容忽视

    Institute of Scientific and Technical Information of China (English)



    So far there is no clear and accurate definition for burns due to specific causes,though they are encountered sometimes.Burns due to specific causes sometimes are neglected because of their low incidence,and many surgeons,even burn specialists are not familiar with them because of low incidence,thus leading to poor results in the treatment.Burns due to specific causes are often involved in complicated and compound injuries.The treatment is often difficult,leading to delayed wound healing.In this paper,the definition,classification,and clinical characteristics of burns due to specific causes are described.Problems involved in diagnosis and treatment of common ones such as electrical,chemical,and compound burns are discussed.Facing an increase of those bums with specific causes,the author suggests that the research into the prevention and treatment should be highly strengthened.

  8. Acute kidney injury: A rare cause

    Directory of Open Access Journals (Sweden)

    Satish Mendonca


    Full Text Available We present a young lady who consumed hair dye, which contained paraphenylene diamine (PPD, as a means of deliberate self-harm. This resulted in severe angio-neurotic edema for which she had to be ventilated, and thereafter developed rhabdomyolysis leading to acute kidney injury (AKI. The unusual aspect was that the patient continued to have flaccid quadriparesis and inability to regain kidney function. Renal biopsy performed 10 weeks after the dye consumption revealed severe acute tubular necrosis with myoglobin pigment casts. This suggests that PPD has a long-term effect leading to ongoing myoglobinuria, causing flaccid paralysis to persist and preventing the recovery of AKI. In such instances, timely treatment to prevent AKI in the form alkalinization of urine should be initiated promptly. Secondly, because PPD is a nondialyzable toxin, and its long-term effect necessitates its speedy removal, hemoperfusion might be helpful and is worth considering

  9. Esophageal Foreign Body Causing Direct Aortic Injury

    Directory of Open Access Journals (Sweden)

    ECS Lam


    Full Text Available Foreign bodies in the esophagus are uncommon causes of esophageal perforation. Many nonperforating cases are successfully managed by flexible gastroscopy. However, complicated foreign bodies such as those that result in esophageal perforation and vascular injury are best managed surgically. Gastroscopy remains the primary method of diagnosis. A case of a 59-year-old woman who developed retrosternal and intrascapular pain, odynophagia and hematemesis after eating fish is reported. Flexible gastroscopy showed arterial bleeding from the midthoracic esophagus. Computed tomography scan localized a 3 cm fish bone perforating the esophagus with surrounding hematoma. An aortogram did not reveal an actively bleeding aortoesophageal fistula. The fish bone was surgically removed and the patient recovered with no postoperative complications. This case illustrates the importance of early consideration for surgical intervention when confronted with a brisk arterial bleed from the esophagus with suggestive history of foreign body ingestion.

  10. Pain and anxiety experiences of South African adult burn injury patients during physiotherapy management

    L.D. Morris


    Full Text Available A dequate management of procedural pain during physiotherapy management plays an important role in building a trusting relationship betweenthe burn victim and the physiotherapist, and in ensuring desirable functional outcomes. However, the burn pain management regimens currently utilized inburn units, primarily consist of traditional pharmacologic analgesics which areassociated with numerous side-effects and alone are often reported as inadequateto alleviate procedural pain, warranting safer and effective adjunct therapies.Prior to the introduction and implementation of adjunct therapies into a developing world, it is imperative that the current situation in a burn unit, in terms of whether or not the pain management regimens in place are adequate, is first assessed, due to cost concerns. The following short report exemplifies the pain and anxiety experiences of a small number of burn injury patients during physiotherapy at the Tygerberg Hospital adult burn unit, South A frica.  It was hypothesized that the results of this study would underpin whether adult burn injury patients in a developing countryrequire adjunct therapies during physiotherapy management to supplement traditional pharmacologic analgesics inmanaging their procedural pain and subsequent anxiety.

  11. Reduction of progressive burn injury by using a new nonselective endothelin-A and endothelin-B receptor antagonist, TAK-044: an experimental study in rats. (United States)

    Battal, M N; Hata, Y; Matsuka, K; Ito, O; Matsuda, H; Yoshida, Y; Kawazoe, T


    Endothelins are well-known vasoconstrictor peptides produced by vascular endothelial cells that have been reported to have a fundamental role in regulation of the systemic blood circulation. Plasma levels of endothelins are increased by burn injury, which also causes thrombosis and occlusion of vessels in the dermis as well as a vascular response in the adjacent uninjured dermis. Diminished blood flow leads to progressive ischemia and necrosis of the dermis beneath and around the burn (zone of stasis). If blood flow could be restored in this zone, secondary tissue damage would be minimized. In this study we examined the effects of a new nonselective endothelin receptor antagonist, TAK-044 (Takeda Chemical Industries, Ltd., Osaka, Japan), on burn trauma in rats. Fifty male Sprague-Dawley rats weighing an average of 450 gm were burned with a brass probe that produced a row of three burns 10 x 30 mm in size and two intervening unburned areas 5 x 30 mm in size. Rats were divided into five groups of 10 animals. Four groups received 0.01, 0.1, 1 or 10 mg/kg of TAK-044 via the dorsal vein of the penis immediately after burn trauma, while the control group received the same volume of saline. Skin blood flow was measured with a laser-Doppler flowmeter, and the development of edema and the area of necrotic tissue also were determined. Inhibition of endothelin activity by TAK-044 after burn injury improved microvascular perfusion in the zone of stasis and prevented the progression of tissue damage in this zone. This supports the role of endothelins in the progression of burn injury in the zone of stasis. TAK-044 was most effective in preventing progressive burn damage at a dose of 1 mg/kg. The extent of necrosis and edema was reduced significantly, and blood flow in the zone of stasis was increased in the treated rats.

    Zhang, Wan-Fu; Zhu, Xiong-Xiang; Hu, Da-Hai; Xu, Cheng-Feng; Wang, Yun-Chuan; Lv, Gen-Fa


    Nonmetabolic effects of intensive insulin therapy in critically ill patients have been reported, but the underlying mechanisms are unclear. This study was designed to test the hypothesis that intensive insulin treatment would attenuate burn-induced acute lung injury by protecting the pulmonary microvascular endothelium. The rat model of burn injury was achieved by exposure to 92°C water for 18 seconds. The rats were randomly allocated into the sham, burn/normal saline (NS), and burn/intensive insulin treatment groups. Blood glucose level was maintained between 5 and 7 mmol/L in rats in the burn/intensive insulin treatment group. Pulmonary injury was assessed by hematoxylin and eosin staining, scanning electron microscopy, bronchoalveolar lavage fluid protein concentrations, the lung wet:dry weight ratio, and lung myeloperoxidase activity. Pulmonary microvascular endothelial cells were examined by transmission electron microscopy. Western blotting was used to determine the protein expression of caspase-3. Intensive insulin treatment markedly attenuated the acute lung injury, revealed by improvements in histological features and significant decreases in bronchoalveolar lavage fluid protein concentrations, pulmonary wet:dry weight ratio, and myeloperoxidase activity at 12 hours after injury (P insulin treatment group when compared with the burn/NS group. Overall, intensive insulin treatment efficiently attenuated pulmonary microvascular endothelial cell dysfunction, decreased cell apoptosis, and inhibited acute lung injury after a burn. These findings may be useful in preventing organ failure after burn injury.

    Background This study evaluated factors influencing early and late occurrence of AKI in severely burned patients and assessed the relationship between time of occurrence of AKI and mortality of AKI patients. Material/Methods Renal function was evaluated at 3 time points: at admission, at the critical point or middle point of hospitalization, and at the endpoint for which death or a discharge from the center was considered. AKI criteria were: decrease in GFR of less than 60 ml/min at admission, decrease in GFR of more than 75% compared to baseline, and decrease in the daily diuresis of less than 500 ml/24 h. Results At admission, 15.1% of the patients had eGFR burns, respiratory failure, low protein concentration (for all ppatients. Mortality was 100% with the initial GFR ≥60, 100% with the initial GFR patients and mortality in this group was 79.2%. Mortality in the entire group with AKI was 88.0% versus 24.5%. Conclusions The frequent occurrence of AKI, especially early, worsens the prognosis for survival. Assessment of renal function should be included in the prognostic scales for burned patients.

    Full Text Available Objectives: Burn injury is one of the most health-threatening problems in the world. Malva sylvestris (M. sylvestris flowershave a high mucilage content and are used as a remedy for cut wound and dermal infected wounds in Iranian folklore Medicine. The purpose of this study was to investigate the effect of M. sylvestris cream on the second degree burn injury in rats. Materials and Methods: Five groups of 10 rats per group were burned with hot metal plate. Animals were administrated divided as control, normal saline, standard silver sulfadiazine 1% (SSD, 5% M. sylvestris, and 10% M. sylvestris into separate groups. Wound area, percentage of wound contraction, and histological and bacteriological assessments were evaluated. Results: Wound sizes were not significantly different among groups on 1st and 3rd days after burn injury, while they were significantly different among groups after 7th day post-burn injury. The average areas of wounds on the 15th day were 7.5±2.9, 6.7±2, 10.5±1.6, 4.7±2, and 4.5±2 cm2 for base cream, normal saline, SSD, 5% M. sylvestris, and 10% M. sylvestris, respectively. The results of histology exhibited well-formed horizontally-oriented collagen fibers in MS topical treatment groups. Microorganisms existed in the SSD group were most probably Staphilococcus epidermitis and for NS group were staphylococcus saprophiteccus. Conclusion: M. sylvestris cream improved histological changes of tissue components in the process of healing when compared with SSD cream. Therefore, it can be used as a topical treatment agent for burn wound.

    Victims of fire accidents who sustain both thermal injury to the skin and smoke inhalation have gross evidence of oxidant injury. Therefore, we hypothesized that delivery of vitamin E, an oxygen superoxide scavenger, directly into the airway would attenuate acute lung injury postburn and smoke inhalation. Sheep (N = 17 female, 35 +/- 5 kg) were divided into 3 groups: (1) injured, then nebulized with vitamin E (B&S, Vitamin E, n = 6); (2) injured, nebulized with saline (B&S, Saline, n = 6); and (3) not injured, not treated (Sham, n = 5). While under deep anesthesia with isoflurane, the sheep were subjected to a flame burn (40% total body surface area, 3rd degree) and inhalation injury (48 breaths of cotton smoke, Ringer lactate solution (4 mL/kg/%burn/24 h) and placed on a ventilator [positive end-expiratory pressure (PEEP) = 5 cm H2O, tidal volume = 15 mL/kg] for 48 h. B&S injury halved the lung alpha-tocopherol concentrations (0.9 +/- 0.1 nmol/g) compared with sham-injured animals (1.5 +/- 0.3), whereas vitamin E treatment elevated the lung alpha-tocopherol concentrations (7.40 +/- 2.61) in the injured animals. B&S injury decreased pulmonary gas exchange (PaO2/FiO2 ratios) from 517 +/- 15 at baseline to 329 +/- 49 at 24 h and to 149 +/- 32 at 48 h compared with sham ratios of 477 +/- 14, 536 +/- 48, and 609 +/- 49, respectively. Vitamin E treatment resulted in a significant improvement of pulmonary gas exchange; ratios were 415 +/- 34 and 283 +/- 42 at 24 and 48 h, respectively. Vitamin E nebulization therapy improved the clinical responses to burn and smoke inhalation-induced acute lung injury.

    BACKGROUND Pain related to burn injuries is one of the most troublesome pain intensity. This study aimed to investigate the effect of massage on anticipatory anxiety, procedural pain intensity, vital signs and relaxation level of patients with burn injury. METHODS In this quasi-experimental study, through convenience sampling, 60 hospitalized adult burn patients were selected from a specialized burn and reconstructive hospital. Subjects were assigned to massage and control groups through simple randomization. Massage was offered by using non aromatic oil about 10-15 minutes before wound care on intact part of the body once a day for 20 minutes on patients’ bedside for 3 consecutive days. In the 3 days, the control group did not received any massage and were asked to stay at bed. Demographic and clinical characteristics and vital signs, Visual Analogue Scale and the Persian version of Burn Specific Pain Anxiety Scale were used to determine baseline and procedural pain, anxiety and relaxation levels and anticipatory anxiety. RESULTS No significant difference was noted between mean score of pain intensity, anxiety and relaxation level, and vital signs in massage and control groups after intervention following wound care. In massage and control groups, there was no significant differences between mean scores of anticipatory anxiety before and after intervention. There was no significant difference between the mean scores of anticipatory anxiety in massage and control groups after intervention prior wound care. CONCLUSION Massage was shown not to have any effect on anticipatory anxiety and procedural pain. PMID:28289612

  20. Predictive Value of IL-8 for Sepsis and Severe Infections After Burn Injury: A Clinical Study. (United States)

    Kraft, Robert; Herndon, David N; Finnerty, Celeste C; Cox, Robert A; Song, Juquan; Jeschke, Marc G


    The inflammatory response induced by burn injury contributes to increased incidence of infections, sepsis, organ failure, and mortality. Thus, monitoring postburn inflammation is of paramount importance but, so far, there are no reliable biomarkers available to monitor and/or predict infectious complications after burn. As interleukin 8 (IL-8) is a major mediator for inflammatory responses, the aim of our study was to determine whether IL-8 expression can be used to predict postburn sepsis, infections, and mortality. Plasma cytokines, acute-phase proteins, constitutive proteins, and hormones were analyzed during the first 60 days after injury from 468 pediatric burn patients. Demographics and clinical outcome variables (length of stay, infection, sepsis, multiorgan failure [MOF], and mortality) were recorded. A cutoff level for IL-8 was determined using receiver operating characteristic analysis. Statistical significance is set at P Patients were grouped according to their average IL-8 levels relative to this cutoff and stratified into high (H) (n = 133) and low (L) (n = 335) groups. In the L group, regression analysis revealed a significant predictive value of IL-8 to percent of total body surface area burned and incidence of MOF (P inflammatory and acute-phase responses compared with the L group (P burn patients.

    The authors investigated endothelial function using flow-mediated dilatation (FMD) in burn patients. This study was done in burn patients with specific criteria on admission. Blood lipid profile at 1st day, high-sensitivity C-reactive protein, and FMD were assessed at 1st and 7th days, as well as at 1st and 3rd months. The highest values of high-sensitivity C-reactive protein were detected on the 7th day, which were significantly higher than those at 1st and 3rd months. The lowest value of FMD was observed on the 7th day. FMD values were higher during the 1st month compared with the 7th day. The highest value of FMD was detected in the 3rd month. It was found that FMD values measured at 7th day and 1st month were significantly lower in patients with a burn percentage of 40 or greater. Our results suggest that inflammation is more prominent on 7th day following burn. The decrease in FMD values on 7th day after injury can be attributed to endothelial damage. The increase in FMD on 3rd month after burn is attributable to effective burn treatment and gradual decrease of inflammatory mediators. The data from this study suggest that there is endothelial dysfunction and low-grade inflammation in burn patients. This condition is more prominent in patients with a burn ratio greater than 40%. Burn patients more frequently have impaired FMD, which may be indicative of arterial endothelial dysfunction and a marker for increased atherosclerosis.

    Time-course microarray experiments are capable of capturing dynamic gene expression profiles. It is important to study how these dynamic profiles depend on the multiple factors that characterize the experimental condition under which the time course is observed. Analytic methods are needed to simultaneously handle the time course and factorial structure in the data. We developed a method to evaluate factor effects by pooling information across the time course while accounting for multiple testing and nonnormality of the microarray data. The method effectively extracts gene-specific response features and models their dependency on the experimental factors. Both longitudinal and cross-sectional time-course data can be handled by our approach. The method was used to analyze the impact of age on the temporal gene response to burn injury in a large-scale clinical study. Our analysis reveals that 21% of the genes responsive to burn are age-specific, among which expressions of mitochondria and immunoglobulin genes are differentially perturbed in pediatric and adult patients by burn injury. These new findings in the body's response to burn injury between children and adults support further investigations of therapeutic options targeting specific age groups. The methodology proposed here has been implemented in R package "TANOVA" and submitted to the Comprehensive R Archive Network at It is also available for download at

    Full Text Available The purpose of this study was the description of sports injuries sustained by campers at summer camps, aged 7-15 years. A sample of 8 camps from the Greek camp population participated in this sport injury surveillance study. Doctors and camp directors completed reports detailing the number of sports injuries events sustained and provided specific information about each event. During the period of the study, 337 sport injury reports were completed. A total of 237 (70.3% boys and 100 (29.7% girls reported having a sport injury. Age of campers sustaining a sport injury was 10-12 years old (60.8%. The frequency of sports injuries was highest during the first camp season. The leading causes of sports injuries in children’s were: falls, crushed by object, collision with other person and slips. Cut/scratch injuries were the most common diagnoses (38.9%. Football, basketball and volleyball were the most frequent sport activities for injuries. Reports based surveillance systems can be successfully used to conducts sport injury surveillance among children attending summer camps. Data collected via such systems can be used to calculate sports injury rates, to describe patterns of sport injury and to identify risk factors for camper – related sport injuries. The results provide necessary information to develop prevention interventions to decrease the number of youth whose camp experiences are negatively affected by sport injury.

    Trauma such as burns induces a hypermetabolic response associated with altered central carbon and nitrogen metabolism. The liver plays a key role in these metabolic changes; however, studies to date have evaluated the metabolic state of liver using ex vivo perfusions or isotope labeling techniques targeted to specific pathways. Herein, we developed a unique mass balance approach to characterize the metabolic state of the liver in situ, and used it to quantify the metabolic changes to experimental burn injury in rats. Rats received a sham (control uninjured), 20% or 40% total body surface area (TBSA) scald burn, and were allowed to develop a hypermetabolic response. One day prior to evaluation, all animals were fasted to deplete glycogen stores. Four days post-burn, blood flow rates in major vessels of the liver were measured, and blood samples harvested. We combined measurements of metabolite concentrations and flow rates in the major vessels entering and leaving the liver with a steady-state mass balance model to generate a quantitative picture of the metabolic state of liver. The main findings were: (1) Sham-burned animals exhibited a gluconeogenic pattern, consistent with the fasted state; (2) the 20% TBSA burn inhibited gluconeogenesis and exhibited glycolytic-like features with very few other significant changes; (3) the 40% TBSA burn, by contrast, further enhanced gluconeogenesis and also increased amino acid extraction, urea cycle reactions, and several reactions involved in oxidative phosphorylation. These results suggest that increasing the severity of injury does not lead to a simple dose-dependent metabolic response, but rather leads to qualitatively different responses.

    Limited research exists examining long-term mental and physical health outcomes in adult survivors of pediatric burns. The authors examine the postinjury lifetime prevalence of common mental and physical disorders in a large pediatric burn cohort and compare the results with matched controls. Seven hundred and forty five survivors of childhood burns identified in the Burn Registry (1% between April 1, 1988 and March 31, 2010) were matched 1:5 to the general population based on age at time of injury (index date), sex, and geographic residence. Postinjury rate ratio (RR) was used to compare burn cases and control cohorts for common mental and physical illnesses through physician billings, and hospital claims. RR was adjusted for sex, rural residence, and income. Compared with matched controls, postburn cases had significantly higher RR of all mental disorders, which remained significant (P < .05) after adjustment (major depression RR = 1.5 [confidence limit {CL}: 1.2-1.8], anxiety disorder RR = 1.5 [CL: 1.3-1.8), substance abuse RR = 2.3 [CL: 1.7-3.2], suicide attempt RR = 4.3 [CL: 1.6-12.1], or any mental disorder RR = 1.5 [CL: 1.3-1.8]). The relative rate of some physical illnesses was also significantly increased in burn survivors: arthritis RR = 1.2 (CL: 1.1-1.4), fractures RR = 1.4 (CL: 1.2-1.6), total respiratory morbidity RR = 1.1 (CL: 1.02-1.3), and any physical illness RR = 1.2 (CL: 1.1-1.3). Adult survivors of childhood burn injury have significantly increased rates of postburn mental and physical illnesses. Screening and appropriate management of these illnesses is essential when caring for this population.

    Full Text Available Melatonin is indoleamine hormone derived from L-tryptophan. Due to its lipophilic nature, it is accessible to every cell. Melatonin has immunomodulatory and antioxidant activities thus protecting tissue injury. Heat shock proteins such as HSP32 known as heme oxygenase-1 (HO-1 possesses antioxidant, anti-inflammatory, and vasodilatory properties and plays an important role in the protecting of tissues from several stresses. The aim of study is to investigate the expression of HO-1 in gastric mucosa and its connection with oxidative stress and melatonin mediated protection after thermal injury. On rats back, under anesthesia, third degree burn was applied involving 30% of total body surface area (TBSA. Melatonin (10 mg per kg body mass was injected i.p. immediately and 12 hours after thermal skin injury. We used tissue malondialdehyde (MDA, lipid peroxidation product, as a marker of oxidative stress. Gastric mucosa histopathology were observed on light microscopy and light immunohistochemistry investigating the HO-1 too. Results: The levels of MDA in gastric mucosa were elevated (p< 0.05. The HO-1 expression was significantly increased in rats with trauma. Melatonin inhibited elevation in lipid peroxidation product and augmented the increase in expression of HO-1 in the gastric mucosa. In conclusion, our data suggest that HO-1 induction following burn injury is an adaptive response protecting gastric mucosal against further oxidative damage. Melatonin increased the antioxidant capacity and restricted burn-induced oxidative damage in gastric mucosa and thus could be used therapeutically in organ protection.

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

    In a recent study, we have shown a rapid inflammatory cell influx across the glandular epithelium and strong proinflammatory cytokine expression at 4 hours after inhalation injury. Studies have demonstrated a significant role of nuclear factor kappa B in proinflammatory cytokine gene transcription. This study examines the acute airway inflammatory response and immunohistochemical detection of p65, a marker of nuclear factor kappa B activation, in sheep after smoke inhalation and burn injury. Pulmonary tissue from uninjured sheep and sheep at 4, 8, 12, 24, and 48 hours after inhalation and burn injury was included in the study. Following immunostaining for p65 and myeloperoxidase, the cell types and the percentage of bronchial submucosal gland cells staining for p65 and the extent of myeloperoxidase stained neutrophils in the bronchial submucosa were determined. Results indicate absence of detection of P65 before 12 hours after injury. At 12 hours after injury, strong perinuclear staining for p65 was evident in bronchial gland epithelial cells, macrophages, and endothelial cells. Bronchial submucosal gland cells showed a significant increase in the percentage of cells stained for p65 compared with uninjured animals and earlier times after injury, P macrophages, and endothelial cells. Quantitation of the neutrophil influx into the bronchial submucosa showed a significant increase compared with uninjured tissue at 24 and 48 hours after injury, P < .05. In conclusion, immunohistochemical detection of activated p65 preceded the overall inflammatory response measured in the lamina propria. However, detection of p65 did not correlate with a recent study showing rapid emigration of neutrophils at 4 hours postinjury. Together, these results suggest that p65 immunostaining may identify cells that are activated to produce proinflammatory cytokines after injury; however, the immunoexpression may not adequately reflect the temporal activation of gene transcription that may

    Wang, Shuxing; Lim, Grewo; Yang, Liling; Zeng, Qing; Sung, Backil; Jeevendra Martyn, J A; Mao, Jianren


    Management of pain after burn injury is an unresolved clinical issue. In a rat model of hindpaw burn injury, we examined the effects of systemic morphine on nociceptive behaviors following injury. Injury was induced by immersing the dorsal part of one hindpaw into a hot water bath (85 degrees C) for 4, 7, or 12 s under pentobarbital anesthesia. Mechanical allodynia to von Frey filament stimulation and thermal hyperalgesia to radiant heat were assessed. Burn injury induced by the 12-s (but not 4-, or 7-s) hot water immersion resulted in reliable and lasting mechanical allodynia and thermal hyperalgesia evident by day 1. In addition, there was an upregulation of protein kinase Cgamma and a progressive downregulation of mu-opioid receptors within the spinal cord dorsal horn ipsilateral to injury as revealed by immunohistochemistry and Western blot. In both injured and sham rats, the anti-nociceptive effects of subcutaneous morphine were examined on post-injury days 7 and 14. While the morphine AD50 dose was comparable on day 7 between burn (1.61 mg/kg) and control (1.7 mg/kg) rats, the morphine dose-response curve was shifted to the right in burn-injured rats (4.6 mg/kg) on post-injury day 14 as compared with both the injured rats on post-injury day 7 and sham rats on day 14 (1.72 mg/kg). These data indicate that hindpaw burn injury reliably produces persistent mechanical allodynia and thermal hyperalgesia and that the reduced efficacy of morphine anti-nociception in chronic burn injury may be in part due to a downregulation of spinal mu-opioid receptors.

  15. The Epidemiology of Emergency Department-Treated Burn Injuries Associated with Portable Heaters in the United States, 2003-2013. (United States)

    Brooks, Raina D; McGwin, Gerald

    The purpose of this study is to examine the epidemiology of portable space heater-related burn injuries among an emergency department nationally representative population of the United States. The data analyzed in this study were collected from the Consumer Products Safety Commission's 2003-2013 National Electronic Injury Surveillance System. There were approximately 53,636 space heater-related thermal burn injuries attributed to portable space heaters from 2003 to 2013. The rate of injuries was relatively constant during the 10-year span. The number of burn injuries was highest during winter months. Young children, older adults, males, and Blacks had the highest rates of injury. The body part most commonly injured was the hand, which accounted for 33.3% of all burn injuries. It is important to understand the characteristics of persons who have an increased risk of portable space heater burn and trip/fall injuries, so that preventative methods and awareness strategies can be used to help reduce the number of annual portable space heater injuries.

  18. Midazolam exacerbates morphine tolerance and morphine-induced hyperactive behaviors in young rats with burn injury. (United States)

    Song, Li; Wang, Shuxing; Zuo, Yunxia; Chen, Lucy; Martyn, Jeevendra A; Mao, Jianren


    Midazolam and morphine are often used in pediatric intensive care unit (ICU) for analgesia and sedation. However, how these two drugs interact behaviorally remains unclear. Here, we examined whether (1) co-administration of midazolam with morphine would exacerbate morphine tolerance and morphine-induced hyperactive behaviors, and (2) protein kinase C (PKC) would contribute to these behavioral changes. Male rats of 3-4 weeks old were exposed to a hindpaw burn injury. In Experiment 1, burn-injured young rats received once daily saline or morphine (10mg/kg, subcutaneous, s.c.), followed 30min later by either saline or midazolam (2mg/kg, intraperitoneal, i.p.), for 14 days beginning 3 days after burn injury. In Experiment 2, young rats with burn injury were administered with morphine (10mg/kg, s.c.), midazolam (2mg/kg, i.p.), and chelerythrine chloride (a non-specific PKC inhibitor, 10nmol, intrathecal) for 14 days. For both experiments, cumulative morphine anti-nociceptive dose-response (ED50) was tested and hyperactive behaviors such as jumping and scratching were recorded. Following 2 weeks of each treatment, ED50 dose was significantly increased in rats receiving morphine alone as compared with rats receiving saline or midazolam alone. The ED50 dose was further increased in rats receiving both morphine and midazolam. Co-administration of morphine and midazolam also exacerbated morphine-induced hyperactive behaviors. Expression of the NR1 subunit of the N-methyl-d-aspartate (NMDA) receptor and PKCγ in the spinal cord dorsal horn (immunohistochemistry; Western blot) was upregulated in burn-injured young rats receiving morphine alone or in combination with midazolam, and chelerythrine prevented the development of morphine tolerance. These results indicate that midazolam exacerbated morphine tolerance through a spinal NMDA/PKC-mediated mechanism.

  19. Neutrophil dysfunction after thermal injury: alteration of phagolysosomal acidification in patients with large burns. (United States)

    Bjerknes, R; Vindenes, H


    The neutrophil phagolysosomal acidification during phagocytosis of Staphylococcus aureus was examined in six patients with large burns, using a flow cytometric technique allowing the simultaneous measurement of phagocytosis and phagolysosomal pH. The kinetics of neutrophil phagolysosomal acidification were altered during the first 20 days following injury, as the initial alkalinization of the phagolysosomes documented in control neutrophils could not be demonstrated in patient cells. Only at discharge and follow-up were the kinetics of phagolysosomal acidification normal. In addition, measurements of neutrophil maximal phagolysosomal acidification showed a lower pH in patient phagolysosomes than in the controls during the first 5 days of hospitalization. The changes of phagolysosomal acidification did not correlate with the alterations of neutrophil maturity or phagocytic capacity. The results demonstrate alterations of an oxygen-independent microbicidal mechanism in neutrophils from patients with large burns, which may contribute to the reduced capacity of neutrophil intracellular killing following thermal injury.

    Full Text Available Camphor is a waxy white sublimating chemical derived from natural as well as synthetic sources and widely used in various communities worldwide for a number of medicinal, culinary, and religious reasons. Camphor is burnt as an offering to God in many religious communities. We report three incidences of self inflicted injury from burning camphor on the palm resulting in full thickness burns. Non-suicidal self-injury is socially unacceptable destruction or alteration of body tissue when there is no suicidal intent or pervasive developmental disorder and we have explored an association between this and burn injury. This report also highlights the unique social and cultural pattern of this burn injury and the importance of psycho-therapeautic help for these victims.

  3. Hair dryer burns in children. (United States)

    Prescott, P R


    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.

  4. Injuries caused by pigs in Papua New Guinea. (United States)

    Barss, P; Ennis, S

    Pigs are intelligent animals that can be formidable adversaries to humans because of their sharp tusks and their ability to attack swiftly. Domestic and feral pigs have an important role in the ecology of village life in Melanesia. A six-year review of all injuries that were caused by pigs that were referred from the villages in Milne Bay Province, Papua New Guinea, to the Provincial Hospital was completed. Some of the injuries that were seen among the 20 patients who were studied included: three penetrating abdominal injuries with prolapse and strangulation of the intestine; a "sucking" chest wound; bilateral pneumothoraces; two infected open fractures of the radius and the ulna; a perforating injury of the knee with septic arthritis; a hand injury with laceration of multiple tendons; an arterial injury of the wrist; injury of a tibial nerve with foot drop; and a severe scrotal injury with exposure of the testicles. Most injuries resulted from the hunting of feral pigs. Adult male hunters who used dogs and carried only one spear were injured most frequently. Wounds from injuries by pigs are deep, often involve multiple critical structures, and are grossly contaminated. Resuscitation requires the administration of fluid and often blood. Treatment includes irrigation, debridement and closure of the wound. The principles of managing such injuries, the prevention of injuries, the ecology of pigs and humans, human infections originating from pigs, and safer methods of hunting pigs are discussed.

    Objective To explore the speciality,diagnosis,cure principle of serious brain injury coexisting with nultiple injuries caused by traffic accidents.Methods To analyze the clinic data of 69 cases of serious rain injury combined by oter parts of injuries caused by traffic accidents received from January 1998 to April 1999.Results This type of injury took up 11.5 percent of brain injuries in the same term and 33.6 percent of serious brain injuries.The specialities of the injury are that most of them were pedestrians crashed by vehicles.Coesisting injuries including chest injury and limb fractures accounted for a large part.The brain injury usally presented profound disturbance of consciousness,being dangerous and complicated,and a high ISS value.After treatment 13 cases died,9 cases was heavily crippled,11 cases lightly crippled,and 36 cases recovered.The death was usually caused by brain injury.Conclusions Road traffic accidents increased substantially every year.Most of them are related with violating drive rules and regulations.It is important to decrease the road traffic accidents by strengthening propaganda on traffic safety and traffic management.The main principles for salvage should emphasize the importance of pre-hospital emergency rescue and the accurate diagnosis rate,especially the distinction between coma and shock.The priority should be put on those injuries threatening to life.

  6. Pulmonary expression of nitric oxide synthase isoforms in sheep with smoke inhalation and burn injury. (United States)

    Cox, Robert A; Jacob, Sam; Oliveras, Gloria; Murakami, Kazunori; Enkhbaatar, Perenlei; Traber, Lillian; Schmalstieg, Frank C; Herndon, David N; Traber, Daniel L; Hawkins, Hal K


    Previous studies have indicated increased plasma levels of inducible nitric oxide synthase in lung. This study further examines the pulmonary expression of nitric oxide synthase (NOS) isoforms in an ovine model of acute lung injury induced by smoke inhalation and burn injury (S+B injury). Female range bred sheep (4 per group) were sacrificed at 4, 8, 12, 24, and 48 hours after injury and immunohistochemistry was performed in tissues for various NOS isoforms. The study indicates that in uninjured sheep lung, endothelial (eNOS) is constitutively expressed in the endothelial cells associated with the airways and parenchyma, and in macrophages. Similarly, neuronal (nNOS) is constitutively present in the mucous cells of the epithelium and in neurons of airway ganglia. In uninjured lung, inducible (iNOS) was present in bronchial secretory cells and macrophages. In tissue after S+B injury, new expression of iNOS was evident in bronchial ciliated cells, basal cells, and mucus gland cells. In the parenchyma, a slight increase in iNOS immunostaining was seen in type I cells at 12 and 24 hours after injury only. Virtually no change in eNOS or nNOS was seen after injury.

Cement water had continuously soaked his shirt while he was planing a freshly applied wet cement ceiling with his right arm upwards. The cement did not contain special additives, so the normal alkalinity of wet cement and occlusion effects caused the erosion. The farmer sued the manufacturer of the cement for damages because of missing warning notices. The court decided in his favor.

  15. Bacterial Respiratory Tract Infections are Promoted by Systemic Hyperglycemia after Severe Burn Injury in Pediatric Patients (United States)

    Kraft, Robert; Herndon, David N; Mlcak, Ronald P; Finnerty, Celeste C; Cox, Robert A; Williams, Felicia N; Jeschke, Marc G


    Background Burn injuries are associated with hyperglycemia leading to increased incidence of infections with pneumonia being one of the most prominent and adverse complication. Recently, various studies in critically ill patients indicated that increased pulmonary glucose levels with airway/blood glucose threshold over 150 mg/dl lead to an overwhelming growth of bacteria in the broncho-pulmonary system, subsequently resulting in an increased risk of pulmonary infections. The aim of the present study was to determine whether a similar cutoff value exists for severely burned pediatric patients. Methods One-hundred six severely burned pediatric patients were enrolled in the study. Patients were divided in two groups: high (H) defined as daily average glucose levels >75% of LOS >150 mg/dl), and low (L) with daily average glucose levels >75% of the LOS pneumonia, atelectasis, and acute respiratory distress syndrome (ARDS) were assessed. Incidence of infections, sepsis, and respiratory parameters were recorded. Blood was analyzed for glucose and insulin levels. Statistical analysis was performed using Student’s t-test and chi-square test. Significance was set at pPatient groups were similar in demographics and injury characteristics. Pneumonia in patients on the mechanical ventilation (L: 21% H: 32%) and off mechanical ventilation (L: 5% H: 15%), as well as ARDS were significantly higher in the high group (L: 3% H: 19%), pPatients in the high group required significantly longer ventilation compared to low patients (ppneumonia confirming the previous studies in critically ill patients.

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

    Full Text Available Alan D Rogers, Marc G Jeschke Ross Tilley Burn Centre, Division of Plastic and Reconstructive Surgery, Department of Surgery, Sunnybrook Health Sciences Centre, University of Toronto, Toronto, ON, Canada Abstract: Encountered regularly by health care providers across both medical and surgical fields and an increasing socioeconomic burden globally, wound care is severely neglected. Practice is heavily influenced by anecdote rather than evidence-based protocols and industry-biased literature rather than robust randomized controlled trials. Burn units are well placed to address this considerable need, as a result of their infrastructure, their multispecialty staffing, and their need to evolve in light of the declining incidence of major burn injury in developed countries. The aim of this review is to evaluate some of the ideological and practical challenges facing wound practitioners and burn surgeons while managing chronic and complex wounds. It also includes an approach to wound assessment and how to conceptualize and implement dressing strategies and new and existing multimodal therapies.

  1. A Smartphone App and Cloud-Based Consultation System for Burn Injury Emergency Care.

    Directory of Open Access Journals (Sweden)

    Lee A Wallis

    Full Text Available Each year more than 10 million people worldwide are burned severely enough to require medical attention, with clinical outcomes noticeably worse in resource poor settings. Expert clinical advice on acute injuries can play a determinant role and there is a need for novel approaches that allow for timely access to advice. We developed an interactive mobile phone application that enables transfer of both patient data and pictures of a wound from the point-of-care to a remote burns expert who, in turn, provides advice back.The application is an integrated clinical decision support system that includes a mobile phone application and server software running in a cloud environment. The client application is installed on a smartphone and structured patient data and photographs can be captured in a protocol driven manner. The user can indicate the specific injured body surface(s through a touchscreen interface and an integrated calculator estimates the total body surface area that the burn injury affects. Predefined standardised care advice including total fluid requirement is provided immediately by the software and the case data are relayed to a cloud server. A text message is automatically sent to a burn expert on call who then can access the cloud server with the smartphone app or a web browser, review the case and pictures, and respond with both structured and personalized advice to the health care professional at the point-of-care.In this article, we present the design of the smartphone and the server application alongside the type of structured patient data collected together with the pictures taken at point-of-care. We report on how the application will be introduced at point-of-care and how its clinical impact will be evaluated prior to roll out. Challenges, strengths and limitations of the system are identified that may help materialising or hinder the expected outcome to provide a solution for remote consultation on burns that can be

  2. Ubiquitin and stromal cell-derived factor-1α in bronchoalveolar lavage fluid after burn and inhalation injury. (United States)

    Baker, Todd A; Davis, Christopher S; Bach, Harold H; Romero, Jacqueline; Burnham, Ellen L; Kovacs, Elizabeth J; Gamelli, Richard L; Majetschak, Matthias


    The objective of the study was to determine whether the CXC chemokine receptor (CXCR) 4 ligands ubiquitin and stromal cell-derived factor (SDF)-1α are detectable in bronchoalveolar lavage fluid (BALF) after burn and inhalation injury and whether their concentrations in BALF are associated with injury severity, physiological variables, or clinical outcomes. BALF was obtained on hospital admission from 51 patients (48 ± 18 years) with burn (TBSA: 23 ± 24%) and inhalation injury (controls: 10 healthy volunteers, 42 ± 8 years). BALF was analyzed for total protein and for ubiquitin and SDF-1α by enzyme-linked immunosorbent assay. Ubiquitin/SDF-1α levels were normalized to total BALF protein content. The extent of inhalation injury was determined during bronchoscopy using a standardized scoring system. Percent TBSA, Baux scores, revised Baux scores, and clinical variables were documented. Ubiquitin and SDF-1α were detectable in 40% of normal BALF specimens. After injury, ubiquitin was detectable in 90% (P patients (P burn and inhalation injury. Increases in BALF ubiquitin after inhalation injury may maintain CXCR4-mediated lung protection and repair processes. The finding that BALF ubiquitin decreased with higher grades of inhalation injury may provide a biological correlate for an insufficient local inflammatory response after severe inhalation injury.

  3. Application of silver sulfadiazine cream with early surgical intervention in patients suffering from combined burn-blast injury facial tattoos. (United States)

    Ebrahimi, Ali; Kalantar Motamedi, Mohammad Hosein


    Severe combined burn-blast injury is a great challenge to surgical teams due to its high mortality. It also results in unsightly traumatic tattoos. The aims of these case reports were to clarify the clinical characteristic of the dynamite explosion burn-blast facial injuries and discuss appropriate management of these patients. We report two patients suffering from facial burn-blast injury following dynamite explosion in which after primary stabilization, silver sulfadiazine cream was applied to the wounds and 12 hours later the wounds were cleaned under general anesthesia with vigorous saline solution irrigation and brushing. The foreign particles were meticulously removed from wounds and simultaneous repairing of defects was done with nylon 6-0 sutures. We conclude application of silver sulfadiazine cream on facial burn-blast injury tattoos several hours before surgical removal of particles is highly efficacious in facilitating particle removal and attaining a good result following surgical intervention, and primary repair. Treatment of combined burn-blast tattoos is different from other types of tattoos not associated with burns. Debridement and removal of foreign particles under general anesthesia from skin immediately and primary reconstruction of wounds is essential. We recommend application of the topical agent silver sulfadiazine to wounds about 12 hours before surgical intervention.

Although television violence has been associated with adverse effects, data on depiction of fire and burn injury are lacking. We sought to determine whether Saturday-morning television programming, viewed primarily by children, depicts fire and burn injury as safe or without consequence, thus potentially increasing the incidence of burn injury in children. This was a prospective observational study. Saturday-morning children's television programs were videotaped from 7 AM to 11 AM for eight different television networks during a 6-month period. Tapes were scored for scenes depicting fire or smoke by independent observers. Recorded items included show category, scene type, gender target, context of fire, and outcome after exposure to flame. Fire events were documented during programs and their associated commercials. A total of 108 hours of children's programs, 16 hours per network, were recorded. Scenes depicting fire or smoke were identified 1960 times, with 39% of events occurring during the program itself and 61% in commercials. Fire was depicted as either safe or without consequence in 64% of incidents. Action adventure stories accounted for 56% of flame depictions. Overall, one incident involving flame and fire was portrayed for each 3 minutes of television programming. Saturday-morning television programming frequently depicts fire as safe, empowering, or exciting. The incidence of flame use in programming varies between stations but is most prevalent in action/adventure stories. Television commercials, although brief, provide the majority of the misinformation regarding fire. Medical professional societies should alert the public to this potential hazard and recommend responsible portrayal of fire in children's television programming.

  5. Hand chemical burns. (United States)

    Robinson, Elliot P; Chhabra, A Bobby


    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.

  6. Do fentanyl and morphine influence body temperature after severe burn injury? (United States)

    Kahn, Steven Alexander; Beers, Ryan J; Lentz, Christopher W


    Fentanyl lacks the antiinflammatory properties of morphine. Morphine attenuates the inflammatory response through differential stimulation of μ-receptor subtypes. Patients who receive morphine during coronary artery bypass graft have been shown to experience less postoperative fever than those who receive fentanyl. Patients who receive continuous fentanyl infusions in increased room temperatures after thermal injury may be at increased risk to experience higher body temperature than those who receive morphine. The records of 28 patients with >20%TBSA burn in 30 intensive care unit rooms (13 received fentanyl and 15 received morphine or hydromorphone) and 12 trauma patients who received fentanyl in 22°C intensive care unit rooms were reviewed. Mean maximum core temperature and percentage of temperature recordings > 39°C in the first 48 hours of admission were compared between burn patients who received fentanyl, those who did not, and with trauma patients. Burn patients exposed to fentanyl experienced significantly higher temperatures (40.1 ± 0.9°C) compared with those given morphine (38.7 ± 0.8°C) and compared with trauma patients (37.5 ± 2.4°C), P Burn patients on fentanyl had temperatures > 39°C for a higher percentage of time (33 ± 27%) than those without fentanyl (7.2 ± 13%) and trauma patients (1 ± 2.8%), P Burn patients who receive fentanyl in 30°C rooms experience higher body temperatures and are febrile for a higher percentage of time than those receiving morphine only. Morphine has well-established antiinflammatory properties and likely attenuates the postburn inflammatory response more than fentanyl, resulting in lower body temperatures. This phenomenon needs to be further investigated in additional studies.

  7. Plasma proteome response to severe burn injury revealed by 18O-labeled "universal" reference-based quantitative proteomics. (United States)

    Qian, Wei-Jun; Petritis, Brianne O; Kaushal, Amit; Finnerty, Celeste C; Jeschke, Marc G; Monroe, Matthew E; Moore, Ronald J; Schepmoes, Athena A; Xiao, Wenzhong; Moldawer, Lyle L; Davis, Ronald W; Tompkins, Ronald G; Herndon, David N; Camp, David G; Smith, Richard D


    A burn injury represents one of the most severe forms of human trauma and is responsible for significant mortality worldwide. Here, we present the first quantitative proteomics investigation of the blood plasma proteome response to severe burn injury by comparing the plasma protein concentrations of 10 healthy control subjects with those of 15 severe burn patients at two time-points following the injury. The overall analytical strategy for this work integrated immunoaffinity depletion of the 12 most abundant plasma proteins with cysteinyl-peptide enrichment-based fractionation prior to LC-MS analyses of individual patient samples. Incorporation of an 18O-labeled "universal" reference among the sample sets enabled precise relative quantification across samples. In total, 313 plasma proteins confidently identified with two or more unique peptides were quantified. Following statistical analysis, 110 proteins exhibited significant abundance changes in response to the burn injury. The observed changes in protein concentrations suggest significant inflammatory and hypermetabolic response to the injury, which is supported by the fact that many of the identified proteins are associated with acute phase response signaling, the complement system, and coagulation system pathways. The regulation of approximately 35 proteins observed in this study is in agreement with previous results reported for inflammatory or burn response, but approximately 50 potentially novel proteins previously not known to be associated with burn response or inflammation are also found. Elucidating proteins involved in the response to severe burn injury may reveal novel targets for therapeutic interventions as well as potential predictive biomarkers for patient outcomes such as multiple organ failure.

  8. Increased expression of atrogenes and TWEAK family members after severe burn injury in nonburned human skeletal muscle. (United States)

    Merritt, Edward K; Thalacker-Mercer, Anna; Cross, James M; Windham, Samuel T; Thomas, Steven J; Bamman, Marcas M


    Severe burn induces rapid skeletal muscle proteolysis after the injury, which persists for up to 1 year and results in skeletal muscle atrophy despite dietary and rehabilitative interventions. The purpose of this research was to determine acute changes in gene expression of skeletal muscle mass regulators postburn injury. Specimens were obtained for biopsy from the vastus lateralis of a nonburned leg of eight burned subjects (6M, 2F: 34.8 ± 2.7 years: 29.9 ± 3.1% TBSA burn) at 5.1 ± 1.1 days postburn injury and from matched controls. mRNA expression of cytokines and receptors in the tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6) families, and the ubiquitin proteasome E3 ligases, atrogin-1 and MuRF-1, was determined. TNF receptor 1A was over 3.5-fold higher in burn. Expression of TNF-like weak inducer of apoptosis and its receptor were over 1.6 and 6.0-fold higher in burn. IL-6, IL-6 receptor, and glycoprotein 130 were elevated in burned subjects with IL-6 receptor over 13-fold higher. The level of suppressor of cytokine signaling-3 was also increased nearly 6-fold in burn. Atrogin-1 and MuRF-1 were more than 4- and 3-fold higher in burn. These results demonstrate for the first time that severe burn in humans has a remarkable impact on gene expression in skeletal muscle of a nonburned limb of genes that promote inflammation and proteolysis. Because these changes likely contribute to the acute skeletal muscle atrophy in areas not directly affected by the burn, in the future it will be important to determine the responsible systemic cues.

    Background There are controversies about the use of artificial colloids.This research was aimed to determine the effect of various artificial colloids on blood coagulation in the shock stage of severe burn injury.Methods Totally,18 female Ba-Ma mini-pigs were subjected to a 40% total body surface third-degree flame burn under anesthesia.Resuscitation therapy was applied 2 hours after the injury,using the burn shock fluid resuscitation formula commonly accepted in the surgical treatment of burns.The Ba-Ma mini-pigs were randomly assigned to three groups (six pigs in each group):succinylated gelatin group (the artificial colloid used was succinylated gelatin Injection),hydroxyethyl starch group (the artificial colloid used was hydroxyethyl starch (130/0.4)),and allogeneic plasma group (the colloid used was allogeneic plasma).Blood samples were collected from the animals prior to the burn injury and again at intervals of 4,8,24 and 48 hours post-injury.The platelet count (PLT),prothrombin time (PT),international normalized ratio (INR),activated partial thromboplastin time (APTT),and fibrinogen (Fib) were measured,followed by a statistical analysis of all results.Results The PLT of succinylated gelatin group and hydroxyethyl starch group at intervals of 24 and 48 hours were (124.3±52.7),(78.8±16.4)×109/L and (159.0±62.8),(87.3±32.0)×109/L respectively.But in the allogeneic plasma group at intervals of 8,24,and 48 hours were (234.3±52.6),(136.0±47.4),(75.8±31.0)×109/L.The decrease were all statistically significant (P <0.05,P <0.01) when compared to pre-burn ((383.3±77.9),(382.7±65.7),(381.0±49.4)×109/L).The PLT among the three groups,at all the time points,had no statistical difference (P >0.05).Compared to pre-burn ((10.8±0.9),(11.4±0.8),(10.6±0.7) seconds),the PT of succinylated gelatin group and hydroxyethyl starch group at 24 hours were (14.5±1.5) and (16.2±1.3) seconds,whereas in the allogeneic plasma group at 8 and 24 hours the PT were

  10. Self-perceptions of young adults who survived severe childhood burn injury. (United States)

    Russell, William; Robert, Rhonda S; Thomas, Christopher R; Holzer, Charles E; Blakeney, Patricia; Meyer, Walter J


    significantly lower self-concept scores on the TSCS2 physical scale are consistent with the physical disfigurement and handicaps common with major burn injuries, and a strong indication of this group's perception of the first impression made when interacting with others. The survivors seem to feel worthwhile within the contexts of family and friends. Although the major limitation of this study using the TSCS2 is the lack of a matched reference population to compare the burn survivors, the TSCS2 does help in gaining insight into the self-esteem issues of the burn survivor population.

  11. Assessment of electrical burn injury using structured illumination in an in-vivo electrical injury model (United States)

    Nguyen, Thu T. A.; Basiri, Ali; Shupp, J. W.; Moffatt, L. T.; Jordan, M. H.; Jeng, J. C.; Leto, E.; Ramella-Roman, J. C.


    Electrical injury is a devastating and hard to treat clinical lesion. Fully understanding the pathophysiology of electrical trauma is still a challenge for clinicians and scientists. Further elucidating the natural history of this form of tissue injury could be helpful in improving limb salvage and offering stage-appropriate therapy. Multi-spectral imaging technique is a non-invasive technology that can be used to determine optical properties of tissues in and adjacent to injury. Images at different wavelengths can provide essential information related to the pathophysiological condition of the tissue. To promote the applicability of this technique in medical diagnosis, we built a complete experimental model of electrical injury. In this model, electrical injuries were created by a reliable high-tension shock system at preset voltage or current. A thermal camera recorded the change of skin temperature during the electrical shock. Then, a high-resolution spectral imaging system based on structured illumination was used to capture images for post analysis to extrapolate optical properties of the tissue. To test accuracy, this imaging system was calibrated by using a set of epoxy phantoms with known optical properties. In this paper, the results of experiments conducted on rats and discussions on the systemic changes in tissue optical properties before and after electrical shock are presented.

    Full Text Available Introduction: Burns can be very destructive, and severely endanger the health and lives of humans. It maybe cause disability and even psychological trauma in individuals. . Such an event can also lead to economic burden on victim’s families and society. The aim of our study is to evaluate epidemiology and outcome of burn patients referring to emergency department. Methods: This is a cross-sectional study was conducted by evaluation of patients’ files and forensic reports of burned patients’ referred to the emergency department (ED of Akdeniz hospital, Turkey, 2008. Demographic data, the season, place, reason, anatomical sites, total body surface area, degrees, proceeding treatment, and admission time were recorded. Multinomial logistic regression was used to compare frequencies’ differences among single categorized variables. Stepwise logistic regression was applied to develop a predictive model for hospitalization. P<0.05 was defined as a significant level. Results: Two hundred thirty patients were enrolled (53.9% female. The mean of patients' ages was 25.3 ± 22.3 years. The most prevalence of burn were in the 0-6 age group and most of which was hot liquid scalding (71.3%. The most affected parts of the body were the left and right upper extremities. With increasing the severity of triage level (OR=2.2; 95% CI: 1.02-4.66; p=0.046, intentional burn (OR=4.7; 95% CI: 1.03-21.8; p=0.047, referring from other hospitals or clinics (OR=3.4; 95% CI: 1.7-6.6; p=0.001, and percentage of burn (OR=18.1; 95% CI: 5.42-62.6; p<0.001 were independent predictive factor for hospitalization. In addition, odds of hospitalization was lower in patients older than 15 years (OR=0.7; 95% CI: 0.5-0.91; p=0.035. Conclusion: This study revealed the most frequent burns are encountered in the age group of 0-6 years, percentage of <10%, second degree, upper extremities, indoor, and scalding from hot liquids.

    Kuhn, F; Mester, V; Morris, R; Dalma, J


    Aim: To analyse serious eye injuries caused by bottles containing pressurised drinks. Methods: Retrospective review of the databases of US, Hungarian, and Mexican eye injury registries. Results: In the combined database (12 889 injuries), 90 cases (0.7%) were caused by bottle tops or glass splinters. The incidence varied widely: 0.3% (United States), 3.1% (Hungary), and 0.9% (Mexico), as did the agent. Champagne bottle corks were responsible in 20% (United States), 71% (Hungary; p<0.0001), and 0% (Mexico). Most eyes improved, but 26% remained legally blind. Conclusions: The presence of warning labels on champagne bottles appears to reduce cork related eye injuries, as does using plastic bottles and caps. PMID:14693777

  14. Functional and psychological outcomes following burn injury: reduced income and hidden emotions are predictors of greater distress. (United States)

    Reeve, Jeanne; James, Frances; McNeill, Rob; Brown, Paul; Cameron, Linda; Mills, Stephen


    The aim of this study is to determine whether functional and psychosocial outcomes after burn injury in New Zealand are consistent with the international literature. Fifty participants with burns >10% TBSA and a mean of 5.1 years since burn completed a survey that included questionnaires and open-ended questions. The rates of psychosocial distress for this sample were consistent with international reports. Psychological distress was predicted by negative change in income and by reports that the individual has hidden thoughts and emotions from others. Respondents also described positive changes in their life as a result of the burn injury that were independent of negative outcomes. Participants indicated good long-term functional improvement but ongoing psychological distress. Important indicators for poor outcome may be loss of income and reluctance to discuss emotions.

    Treatment with bisphosphonates within the first 10 days of severe burn injury completely prevents bone loss. We therefore postulated that bone resorption occurs early post burn and is the primary explanation for acute bone loss in these patients. Our objective was to assess bone for histological and biomechanical evidence of early resorption post burn. We designed a randomized controlled study utilizing a sheep model of burn injury. Three sheep received a 40 % total body surface area burn under isoflurane anesthesia, and three other sheep received cotton-smoke inhalation and served as control. Burned sheep were killed 5 days post procedure and controls were killed 2 days post procedure. Backscatter scanning electron microscopy was performed on iliac crests obtained immediately postmortem along with quantitative histomorphometry and compression testing to determine bone strength (Young's modulus). Blood ionized Ca was also determined in the first 24 h post procedure as was urinary CTx. Three of three sheep killed at 5 days had evidence of scalloping of the bone surface, an effect of bone resorption, whereas none of the three sheep killed at 2 days post procedure had scalloping. One of the three burned sheep killed at 5 days showed quantitative doubling of the eroded surface and halving of the bone volume compared to sham controls. Mean values of Young's modulus were approximately one third lower in the burned sheep killed at 5 days compared to controls, p = 0.08 by unpaired t test, suggesting weaker bone. These data suggest early post-burn bone resorption. Urine CTx normalized to creatinine did not differ between groups at 24 h post procedure because the large amounts of fluids received by the burned sheep may have diluted urine creatinine and CTx and because the urine volume produced by the burned sheep was threefold that of the controls. We calculated 24 h urinary CTx excretion, and with this calculation CTx excretion/24 h in the burned sheep was

    Alsafran, Salman K; Davis, James S; Tankel, Susan; Varas, Robin; Quintana, Olga; Manning, Ron; Glenn, Candace; Pizano, Louis R; Namias, Nicholas; Schulman, Carl I


    Advances in burn care have decreased mortality in the past 20 years, but affecting elderly mortality rates (>65 years) remain challenging. This study evaluates the impact of home caregiver support on elderly burn patients' mortality. The authors retrospectively reviewed patients aged 65 and older admitted to their burn center from July 1995 to October 2004. Patient demographics, Injury Severity Score, TBSA, and patients' primary caregiver were collected. The outcomes were mortality, disposition, and length of stay and these were evaluated using univariate and subsequently multivariate regression. Significance was calculated at P ≤ .05. A total of 112 patients were included in the analysis. The mean age was 76±8. Male patients constituted 47%, whereas 53% were female patients, and mean TBSA was 21±16%. Thirty patients' primary caregiver was a spouse, for 38 it was a child, and 44 had no caregiver. Fifty-eight patients survived (51.7%), and 54 patients died (48.3%). Only 21% of the survivors had a child as their primary caregiver; however, 48% of the nonsurvivors had a child as the primary caregiver (P ≤ 0.05). On multivariate analysis, age, TBSA, and child as primary caregiver were all independent predictors of mortality. Having a child as a caregiver provided the largest impact, with an odds ratio of 4.4 (95% confidence interval, 1.2-15.62; P = .02).

    Acinetobacter baumannii infections in burn patients may lead to delays in wound healing, graft losses, and development of sepsis. Determining the risk factors for multidrug resistant A. baumannii (MDR-AB) infections is essential for infection control. In the present study, the authors aimed to evaluate risk factors for wound infections caused by A. baumannii in burn patients. The study was conducted at Dicle University Hospital Burn Center, from April 2011 to July 2012, to investigate the risk factors for MDR-AB infections. The data of both the case and control group patients and the result of wound cultures were recorded on a daily basis, on individual forms given for each patient, and analyzed. A total of 30 cases infected with MDR-AB, and 60 uninfected control patients, were included in the study. The mean age (±SD) was 7.7 ± 15.4 years in infected patients and 11.4 ± 16.5 years in uninfected patients. The mean total burn surface area was 13.5 ± 10.9% in uninfected patients and 34.7 ± 16.2% in infected patients. The mean total burn surface area, the abbreviated burn severity index, acute physiological and chronic health evaluation II score, day of admission to hospital, length of hospital stay, first excision day, prior usage of third-generation cephalosporins, and stay in intensive care unit of the infected patients were significantly higher (P infection. Univariate analysis found that high acute physiological and chronic health evaluation II score, first excision time of wound, invasive device usage, admission day to hospital, and prior usage of broad-spectrum antibiotics were risk factors for nosocomial infections. This study showed that multiple factors contribute to multidrug resistance in A. baumannii. A combination of an early diagnosis of wound infections, appropriate antimicrobial treatments, surgical debridement, and early wound closure may be effective in the management.

    Full Text Available Background. We compared the efficacy of P. granatum (P flower extract with that of silver sulfadiazine (SSD for treating thermal burn injuries in rats. Methods. Ten Wistar rats in each group were topically given base cream, normal saline, cream containing 1% SSD, or creams containing 5% or 10% Punica granatum flower extract. The treatments were administered once daily until complete wound healing was observed. The wound area and healing time were assessed. In addition, percentage wound contraction and histopathological characteristics such as neovascularization and collagen formation were determined. The tannin content in P. granatum extract was determined. Results. The decrease in the average size of wounds on day 15 of the treatment was higher in rats treated with creams containing P. granatum extract than in rats treated with cream containing SSD (2.8±0.9 cm2 versus 8.4±3.2 cm2. The wounds completely healed on day 25 of the treatment in rats treated with creams containing P. granatum flower extract compared with those in rats treated with the other agents. Conclusion. These results indicated that P. granatum flower extract promoted wound healing in rats and could be used for managing burn injuries.

  20. 20 Years of Research on Socioeconomic Inequality and Children's—Unintentional Injuries Understanding the Cause-Specific Evidence at Hand

    Directory of Open Access Journals (Sweden)

    Lucie Laflamme


    Studies have been conducted at both area and individual levels, the bulk of which deal with road traffic, burn, and fall injuries. As a whole and for each injury cause separately, their results support the notion that low socioeconomic status is greatly detrimental to child safety but not in all instances and settings. In light of variations between causes and, within causes, between settings and countries, it is emphasized that the prevention of inequities in child safety requires not only that proximal risk factors of injuries be tackled but also remote and fundamental ones inherent to poverty.

  1. Injury-related fear-avoidance and symptoms of posttraumatic stress in parents of children with burns. (United States)

    Willebrand, M; Sveen, J


    Parents of children with burns experience a range of psychological reactions and symptoms, and parents' health is known to impact children's health. So far, there is little research into potential mechanisms that maintain parents' symptoms. The aim was to investigate parental injury-related fear-avoidance, and its associations with injury severity and health measures. Parents (n=107) of children aged 0.4-18 years that sustained burns 0.1-9.0 years previously completed questionnaires on fear-avoidance, posttraumatic stress, and health of the child. Analyses showed that the average level of fear-avoidance was low and positively associated with measures of injury severity and parents' symptoms of posttraumatic stress, and negatively associated with parents' ratings of their child's health. In two separate multiple regressions with parents' symptoms of PTSD and the child's health as dependent variables, fear-avoidance made the largest contribution in both models while injury severity was non-significant. Results were not related to comorbid conditions of the child, scarring, or parent-related socio-demographic variables. In summary, injury-related fear-avoidance is more likely among parents whose children sustain more severe burns. In turn, fear-avoidance contributes significantly to parents' symptoms of PTSD and to poorer health ratings regarding the child, irrespective of injury severity or child comorbidity.

    DEFF Research Database (Denmark)

    Brix, Lau; Isaksen, Christin Rosendahl Graff; Kristensen, Birgitte Hornbæk;

    . Positioning of the ECG module in the imaging plane may contribute to heating of the leads due to this effect [3,4]. As this was the case, this may have contributed to the bruns. Furthermore, we believe that the burns were actually caused by the direct skin contact with the leads and a marginal crossing...... of the assigned compatibility specifications of the leads due to the use of TFE sequences with high SAR values. MRI compatible monitoring systems are only safe when used with proper care. The presented burn cases may have been avoided if space had been provided between the ECG leads and the skin using a cloth......Introduction: The combination of increased magnetic field strength, field gradients and RF power, augments the risk of tissue heating in patients undergoing an MRI examination. This is especially important when the patients have implants or when external devices are in direct contact with the skin...

    Recent growth in the electronics and chemical industries has brought about a progressive increase in the use of hydrofluoric acid (HF), along with the concomitant risk of acute poisoning among HF workers. We report severe cases of inhalation exposure and skin injury which were successfully treated by administering a 5% calcium gluconate solution with a nebulizer and applying 2.5% calcium gluconate jelly, respectively. Case 1: A 52-year old worker used HF for surface treatment after welding stainless steel, and was hospitalized with rapid onset of severe dyspnea. On admission to the critical care medical center he had widespread wheezing and crackles in his lungs. Chest radiograph showed a fine diffuse veiling over both lower pulmonary fields. Severe hypocalcemia with high concentrations of F in serum and urine were disclosed. He was immediately given 5% calcium gluconate solution by intermittent positive-pressure breathing (IPPB), utilizing a nebulizer. On the 21st hospital day, chest film and CT scan did not demonstrate any abnormality. He was discharged very much improved on the 22nd hospital day. Case 2: A 35-year old worker at an electronics factory was admitted to his local hospital with severe skin burn on his face and neck after exposure to 100% HF. Treatment began with immediate copious washing with water for 20 min. Calcium gluconate 2.5% gel (HF burn jelly) was applied to the area as a first-aid measure. Persistent high concentrations of serum and urinary F were disclosed for 2 weeks. After treatment with applications of HF burn jelly, he was confirmed as being completely recovered. The present cases and a review of published data suggest that an adequate method of emergency treatment for accidental HF poisoning is necessary.

    Grieb, Gerrit; Simons, David; Piatkowski, Andrzej; Bernhagen, Jürgen; Steffens, Guy; Pallua, Norbert


    Serum macrophage migration inhibitory factor (MIF) and procalcitonin (PCT) concentrations as well as leucocyte numbers were evaluated in a retrospective study with 23 patients with severe burn injuries. The MIF and PCT concentrations as well as the number of leucocytes (LEU) were monitored over a period of 5 days. The total body surface area (TBSA) and sepsis-related organ failure assessment (SOFA) scores were also evaluated. The MIF, PCT concentrations and leucocyte counts were profoundly increased in all patients with severe burn wounds. At the time of admission into the intensive care unit, no significant differences were observed for the MIF and PCT levels between patients with a TBSApatients with a TBSA>60% (Group 2). After 48 h, however, the MIF and PCT levels reached very high levels in a subgroup of the patients, whereas these levels became normal again in other subgroups. The group of patients with a TBSA>60% was, therefore, subdivided in three groups (subgroups 2a-c). The MIF and PCT data pairs in these subgroups appeared to correlate in an inhomogeneous manner. These levels in the subgroup 2a (i.e., lethal within 5 days) were strongly elevated over those observed in Group 1 (TBSAburn inflammation and systemic inflammatory response syndrome (SIRS) or sepsis with lethal outcome.

  8. [Foreign bodies--uncommon causes of GIT injuries]. (United States)

    Hasala, P; Hadwiger, J; Gryga, A; Folprecht, M


    Injuries to various parts of the digestive tract caused by foreign bodies, frequently deliberately swallowed or inserted using various practics, are less common, however serious injuries. The symptomatology may be vague, credibility is often limited or anamnestic data may be intentionaly missing, which makes the diagnostic process tricky. Undefined, vague signs are related to specificities during the GIT perforation, so called hidden perforation. The recovery is commonly complicated, with a resulting handicap of stool incontinence or of colostomy. This is demonstrated on several subjects, treated in our surgical department.

  9. Clinical application of cultured epithelial autografts on acellular dermal matrices in the treatment of extended burn injuries. (United States)

    Fang, Taolin; Lineaweaver, William C; Sailes, Frederick C; Kisner, Carson; Zhang, Feng


    Achieving permanent replacement of skin in extensive full-thickness and deep partial-thickness burn injuries and chronic wounds remains one of the fundamental surgical problems. Presently, split-thickness skin grafts are still considered the best material for surgical repair of an excised burn wound. However, in burns that affect greater than 50% of total body surface area, the patient has insufficient areas of unaffected skin from which split-thickness skin grafts can be harvested. The use of cultured epithelial (or epidermal) autografts (CEAs) has achieved satisfactory results. But the take rate of CEAs is poor in full-thickness bed or in chronically infected area. Providing temporary cover with allograft skin, or a more permanent allodermis, may increase clinical take. This review aims to (1) describe the use of CEAs in the regeneration of the epidermis, (2) introduce the application of the acellular dermal matrices (ADMs) in the clinics, and (3) enhance understanding of the CEAs applied with ADM as an appropriate strategy to treat the extended burn injuries. The current evidence regarding the cultured epithelial cell or keratinocyte autograft and dermal grafts applied in the treatment of burn injuries was investigated with an extensive electronic and manual search (MEDLINE and EMBASE). The included literature (N=136 publications) was critically evaluated focusing on the efficacy and safety of this technique in improving the healing of the deep dermal and full-thickness burn injuries. This review concluded that the use of ADM with CEAs is becoming increasingly routine, particularly as a life-saving tool after acute thermal trauma.

  10. Psychiatric aspects of burn

    Dalal P


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

  11. Circulating Mitochondrial DAMPs Cause Inflammatory Responses to Injury (United States)

    Zhang, Qin; Raoof, Mustafa; Chen, Yu; Sumi, Yuka; Sursal, Tolga; Junger, Wolfgang; Brohi, Karim; Itagaki, Kiyoshi; Hauser, Carl J.


    Injury causes a systemic inflammatory response syndrome (SIRS) clinically much like sepsis 1. Microbial pathogen-associated molecular patterns (PAMPs) activate innate immunocytes through pattern recognition receptors 2. Similarly, cellular injury can release endogenous damage-associated molecular patterns (DAMPs) that activate innate immunity 3. Mitochondria are evolutionary endosymbionts that were derived from bacteria 4 and so might bear bacterial molecular motifs. We show here that injury releases mitochondrial DAMPs (MTD) into the circulation with functionally important immune consequences. MTD include formyl peptides and mitochondrial DNA. These activate human neutrophils (PMN) through formyl peptide receptor-1 and TLR9 respectively. MTD promote PMN Ca2+ flux and phosphorylation of MAP kinases, thus leading to PMN migration and degranulation in vitro and in vivo. Circulating MTD can elicit neutrophil-mediated organ injury. Cellular disruption by trauma releases mitochondrial DAMPs with evolutionarily conserved similarities to bacterial PAMPs into the circulation. These can then signal through identical innate immune pathways to create a sepsis-like state. The release of such mitochondrial ‘enemies within’ by cellular injury is a key link between trauma, inflammation and SIRS. PMID:20203610

    Full Text Available Inadequate ventilator settings may cause overwhelming inflammatory responses associated with ventilator-induced lung injury (VILI in patients with acute respiratory distress syndrome (ARDS. Here, we examined potential benefits of glutamine (GLN on a two-hit model for VILI after acid aspiration-induced lung injury in rats. Rats were intratracheally challenged with hydrochloric acid as a first hit to induce lung inflammation, then randomly received intravenous GLN or lactated Ringer’s solution (vehicle control thirty min before different ventilator strategies. Rats were then randomized to receive mechanical ventilation as a second hit with a high tidal volume (TV of 15 mL/kg and zero positive end-expiratory pressure (PEEP or a low TV of 6 mL/kg with PEEP of 5 cm H2O. We evaluated lung oxygenation, inflammation, mechanics, and histology. After ventilator use for 4 h, high TV resulted in greater lung injury physiologic and biologic indices. Compared with vehicle treated rats, GLN administration attenuated lung injury, with improved oxygenation and static compliance, and decreased respiratory elastance, lung edema, extended lung destruction (lung injury scores and lung histology, neutrophil recruitment in the lung, and cytokine production. Thus, GLN administration improved the physiologic and biologic profiles of this experimental model of VILI based on the two-hit theory.

    Stingray injuries to the heart are rare, and survivors of this injury are even rarer. To date, there are only three reported survivors of this mode of penetrating cardiac injury, all inflicted by the living animal itself. The following is a report of a stingray injury, inflicted by a human, causing coronary complications 17 years after the injury was sustained.

    Enns, Jessica; Gawaziuk, Justin P; Khan, Sazzadul; Chateau, Dan; Bolton, James M; Sareen, Jitender; Stone, James; Doupe, Malcolm; Logsetty, Sarvesh


    Pediatric burn injuries are common, and the stress of caring for them can affect caregivers' health. This study's objective was to examine the rates of common mental and physical disorders of parents of burn-injured children (cases) compared with matched controls (controls). This is a population-based study linking the Regional Pediatric burn registry with administrative health information. Pediatric burn cases were matched 1:5 with control children from the general population based on age, sex, and geographical location then parents identified. One thousand and twenty-six parental cases and 4858 controls were identified. International Classification of Disease codes were used to identify diagnoses of common mental and physical disorders. Using rates of disease 2 years before and 2 years after the date of burn, the changes in the relative rates of health outcomes were compared between the cases and the controls. The cases had higher rates of postinjury mental and physical illness compared with the matches. However, it was found that controls also had increased rates postindex date and additionally cases had increased rates of preinjury illnesses. There was no difference in the relative rates of illnesses between the groups from pre- to post-index date. The higher rate of illness in cases postinjury could be explained by preinjury illness, and similar rate increases in the control cohort. Evaluation of the effect of a child's burn injury on parents should take into context the preexisting health of the parent. Socioeconomic factors associated with increased risk of burns may also be associated with adverse health outcomes.

  16. Resuscitation after severe burn injury using high-dose ascorbic acid: a retrospective review. (United States)

    Kahn, Steven Alexander; Beers, Ryan J; Lentz, Christopher W


    Resuscitation of burn victims with high-dose ascorbic acid (vitamin C [VC]) was reported in Japan in the year 2000. Benefits of VC include reduction in fluid requirements, resulting in less tissue edema and body weight gain. In turn, these patients suffer less respiratory impairment and reduced requirement for mechanical ventilation. Despite these results, few burn centers resuscitate patients with VC in fear that it may increase the risk of renal failure. A retrospective review of 40 patients with greater than 20% TBSA between 2007 and 2009 was performed. Patients were divided into two groups: one received only lactated Ringer's (LR) solution and another received LR solution plus 66 mg/kg/hr VC. Both groups were resuscitated with the Parkland formula to maintain stable hemodynamics and adequate urine output (>0.5 ml/kg/hr). Patients with >10-hour delay in transfer to the burn center were excluded. Data collected included age, gender, weight, %TBSA, fluid administered in the first 24 hours, urine output in the first 24 hours, and Acute Physiology and Chronic Health Evaluation II score. PaO2 in millimeters mercury:%FIO2 ratio and positive end-expiratory pressure were measured at 12-hour intervals, and hematocrit was measured at 6-hour intervals. Comorbidities, mortality, pneumonia, fasciotomies, and renal failure were also noted. After 7 patients were excluded, 17 patients were included in the VC group and 16 in the LR group. VC and LR were matched for age (42 ± 16 years vs 50 ± 20 years, P = .2), burn size (45 ± 21%TBSA vs 39 ± 15%TBSA, P = .45), Acute Physiology and Chronic Health Evaluation II (17 ± 7 vs 18 ± 8, P = .8), and gender. Fluid requirements in the first 24 hours were 5.3 ± 1 ml/kg/%TBSA for VC and 7.1 ± 1 ml/kg/%TBSA for LR (P < .05). Urine output was 1.5 ± 0.4 ml/kg/hr for VC and 1 ± 0.5 ml/kg/hr for LR (P < .05). Vasopressors were needed in four VC patients and nine LR patients (P = .07). VC patients required vasopressors to maintain mean

  17. The Physiologic Basis of Burn Shock and the Need for Aggressive Fluid Resuscitation. (United States)

    Rae, Lisa; Fidler, Philip; Gibran, Nicole


    Burn trauma in the current age of medical care still portends a 3% to 8% mortality. Of patients who die from their burn injuries, 58% of deaths occur in the first 72 hours after injury, indicating death from the initial burn shock is still a major cause of burn mortality. Significant thermal injury incites an inflammatory response, which distinguishes burns from other trauma. This article focuses on the current understanding of the pathophysiology of burn shock, the inflammatory response, and the direction of research and targeted therapies to improve resuscitation, morbidity, and mortality.

    In the study, we are going to develop a tri-layer membrane as the artificial skin for extensive burn injury. The first layer is a three-dimensional tri-copolymer sponge of gelatin/hyaluronan/chodroitin-6-sulfate with 70% in porosity and 20-100 {mu}m in pore size. The layer is constructed as a dermis analogous layer to stimulate capillaries penetration, to promote dermal fibroblast migration and to induce the secretion of extra-cellular matrix, which provides a better physiological environment for burn patient recovery. The second layer is as so called auto-stripped layer composed by poly-N-isopropyacrylamide (PNIPAAm). The layer will be automatically peeled off from the tri-copolymer layer once the wound site closed and recovered. The third layer is composed by polypropylene (PP) non-woven fabric, which provides an open structure for exudates drainage out that will reduce the risk of second infection. The tri-layer wound dressing has been successfully prepared by subsequently high-energy plasma treatment, {gamma}-ray irradiation, UV light exposure, and lyophilized process. From the results of MTT, IL-8, IL-1{alpha}, IL-6, and TNF-{alpha} measurement, the developed material will not induce tissue inflammatory or immune response. The dermal fibroblasts showed initial contact with the material surface through the radial extension of filopodia followed by cytoplasmic webbing that could be examined by SEM. Dermal fibroblasts subsequently flattened for further proliferation and extra-cellular matrix secretion. Dermal analog layer provides a three-dimensional architecture for normal dermis regeneration. The layer can be completely biodegraded within 4 weeks post-operation. After served as a scaffold for the ingrowth of self-fibroblasts, a normal dermis like layer will be regenerated. The dressing will fall off automatically without any damage once the wound site healed completely.

  19. The efficacy of playing a virtual reality game in modulating pain for children with acute burn injuries: A randomized controlled trial [ISRCTN87413556

    Directory of Open Access Journals (Sweden)

    McRae Sarah E


    Full Text Available Abstract Background The management of burn injuries is reported as painful, distressing and a cause of anxiety in children and their parents. Child's and parents' pain and anxiety, often contributes to extended time required for burns management procedures, in particular the process of changing dressings. The traditional method of pharmacologic analgesia is often insufficient to cover the burnt child's pain, and it can have deleterious side effects 12. Intervention with Virtual Reality (VR games is based on distraction or interruption in the way current thoughts, including pain, are processed by the brain. Research on adults supports the hypothesis that virtual reality has a positive influence on burns pain modulation. Methods This study investigates whether playing a virtual reality game, decreases procedural pain in children aged 5–18 years with acute burn injuries. The paper reports on the findings of a pilot study, a randomised trial, in which seven children acted as their own controls though a series of 11 trials. Outcomes were pain measured using the self-report Faces Scale and findings of interviews with parent/carer and nurses. Results The average pain scores (from the Faces Scale for pharmacological analgesia only was, 4.1 (SD 2.9, while VR coupled with pharmacological analgesia, the average pain score was 1.3 (SD 1.8 Conclusion The study provides strong evidence supporting VR based games in providing analgesia with minimal side effects and little impact on the physical hospital environment, as well as its reusability and versatility, suggesting another option in the management of children's acute pain.

    A 34-year-old woman was admitted to hospital after sustaining a head injury in a motor vehicle accident (day 1). No signs of neurological deficit, skull fracture, brain contusion, or intracranial bleeding were evident. She was discharged without symptoms on day 4. However, headache and nausea worsened on day 8, at which time serum sodium level was noted to be 121 mEq/L. Treatment with sodium chloride was initiated, but serum sodium decreased to 116 mEq/L on day 9. Body weight decreased in proportion to the decrease in serum sodium. Cerebral salt-wasting syndrome was diagnosed. This case represents the first illustration of severe hyponatremia related to cerebral salt-wasting syndrome caused by a minor head injury.

    It is of great importance to know the endogenous mechanism in burn-induced organ injuries,not only for the understanding of pathophysiological processes after burn,but also for guiding the clinical treatment.Recent studies have widened and deepened our scope and understanding of secondary injuries to various organs.However,a unaminous understanding of molecular pathway involved in all burn-induced organ injuries has not been attained.Relatively,the mechanism of endogenous cellular injuries as a result of burn injury could be regarded as a common one to explain the causation of cellular injury,and to guide the prevention and treatment for the burn-induced complications using cytoprotection strategy. This review summarized four aspects of the mechanism of endogenous cellular injuries,including cellular injuries induced by ischemic/hypoxic-oxidative stress,excessive inflammatory factors released by inflammatory cells,immunosuppression caused by suppression of function of adaptive immune cells,and dysfunction of important supportive cells of various organs.

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

  4. Use of cyanide antidotes in burn patients with suspected inhalation injuries in North America: a cross-sectional survey. (United States)

    Dumestre, Danielle; Nickerson, Duncan


    This study aimed to assess the use of cyanide antidotes and the determine the opinion on empiric administration of hydroxocobalamin in North American burn patients with suspected smoke inhalation injuries. An online cross-sectional survey was sent to directors of 90 major burn centers in North America, which were listed on the American Burn Association Web site. A multiple-choice format was used to determine the percentage of patients tested for cyanide poisoning on admission, the current administration of a cyanide antidote based solely on clinical suspicion of poisoning, and the antidote used. To ascertain views on immediate administration of hydroxocobalamin before confirmation of cyanide poisoning an option was included to expand the response in written format. Twenty-nine of 90 burn directors (32%) completed the survey. For the population of interest, the majority of burn centers (59%) do not test for cyanide poisoning on admission and do not administer an antidote based solely on clinical suspicion of cyanide poisoning (58%). The most commonly available antidote is hydroxocobalamin (50%), followed by the cyanide antidote kit (29%). The opinion regarding instant administration of hydroxocobalamin when inhalation injury is suspected is mixed: 31% support its empiric use, 17% do not, and the remaining 52% have varying degrees of confidence in its utility. In North America, most patients burnt in closed-space fires with inhalation injuries are neither tested for cyanide poisoning in a timely manner nor empirically treated with a cyanide antidote. Although studies have shown the safety and efficacy of empiric and immediate administration of hydroxocobalamin, most centers are not willing to do so.

  5. Preparation of asiaticoside-loaded coaxially electrospinning nanofibers and their effect on deep partial-thickness burn injury. (United States)

    Zhu, Lifei; Liu, Xiaoyan; Du, Lina; Jin, Yiguang


    Sodium alginate and chitosan were in favor of wound healing. However, the two polymers were not compatible in one formulation due to the electrostatic interaction. Coaxially electrospinning technology could make two or more noneletrospun polymers to be electrospun in independent core and shell layer. Asiaticoside-loaded coaxially electrospinning nanofibers of alginate, polyvinyl alcohol (PVA) and chitosan (alginate/PVA/chitosan) were prepared and evaluated. Morphologies and microstructure of nanofibers were observed with scanning electron microscopy (SEM) and transmission electron microscopy (TEM). Drug release in vitro of coaxial nanofibers was also evaluated. Deep partial-thickness burn injury were established and used to evaluate the improved healing effect of asiaticoside-loaded coaxial nanofibers. Drug-loaded coaxial nanofibers prepared with the optimized formulations and technologies had the obvious core-shell structure. Coaxial nanofibers showed faster drug release profiles in vitro and this facilitated wound healing. Its healing effect on rats with deep partial-thickness burn injury was also significant based on morphology, wound healing ratio, and pathological sections. Positive expression of vascular endothelial growth factor (VEGF), cluster of differentiation 31 (CD31), and proliferating cell nuclear antigen (PCNA), and down regulation of tumor necrosis factor (TNF) and interleukin-6 (IL-6) also validated the improved effect of wound healing. In general, the asiaticoside-loaded coaxial nanofibers had obvious core-shell structure with smooth surface and uniform diameter. Its healing effect on deep partial-thickness burn injury of rats was obvious. Asiaticoside-loaded coaxial nanofibers provide a novel promising option for treatment of deep partial-thickness burn injury.

  6. Clothing Flammability and Burn Injuries: Public Opinion Concerning an Overlooked, Preventable Public Health Problem. (United States)

    Frattaroli, Shannon; Spivak, Steven M; Pollack, Keshia M; Gielen, Andrea C; Salomon, Michele; Damant, Gordon H


    The objective of this study was to describe knowledge of clothing flammability risk, public support for clothing flammability warning labels, and stronger regulation to reduce the risk. As part of a national survey of homeowners about residential sprinkler systems, the authors included questions about clothing flammability. The authors used an online web panel to sample homeowners and descriptive methods to analyze the resulting data. The sample included 2333 homeowners. Knowledge of clothing flammability and government oversight of clothing flammability risk was low. Homeowners were evenly split about the effectiveness of current standards; however, when presented with clothing-related burn injury and death data, a majority (53%) supported stricter standards. Most homeowners (64%) supported warning labels and indicated that such labels would either have no effect on their purchasing decisions (64%) or be an incentive (24%) to purchase an item. Owners of sprinkler-equipped homes were more likely to support these interventions than owners of homes without sprinkler systems. Public knowledge about clothing flammability risks is low. Most homeowners supported clothing labels to inform consumers of this risk and increased government intervention to reduce the risk.

  7. A case of chemical scalp burns after hair highlights: experimental evidence of oxidative injuries. (United States)

    Bertani, Roberta; Sgarbossa, Paolo; Pendolino, Flavio; Facchin, Giangiacomo; Snenghi, Rossella


    Hair highlights are quite common procedures carried out in hair salons by using a mixture of a lightening powder containing persulfates with a suspension containing hydrogen peroxide: a representative case of chemical scalp burns is described as a consequence of this treatment. The aim of the paper is to demonstrate the strict relationship between the scalp damage and the commercial products used in a case of hair highlighting. The results of some chemical analyses have been reported, showing, in particular, that the chemical reactivity of the mixture changes in the time, thus strongly suggesting that the procedure for the application of the mixture is critical for the occurrence of possible accidents. The presence in the powder of chemical compounds bearing aliphatic chains as surfactants explains the appearance of dramatic symptoms after days due to a slow dissolution of the oxidant compounds in the stratum corneum of skin with no effect in reducing injury of palliative treatments. Safety suggestions and recommendations for producers and workers are also included.

  8. Burn epidemiology and cost of medication in paediatric burn patients. (United States)

    Koç, Zeliha; Sağlam, Zeynep


    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.

  9. Epoetin Alpha and Epoetin Zeta: A Comparative Study on Stimulation of Angiogenesis and Wound Repair in an Experimental Model of Burn Injury

    Directory of Open Access Journals (Sweden)

    Natasha Irrera


    Full Text Available Deep second-degree burns are characterized by delayed formation of granulation tissue and impaired angiogenesis. Erythropoietin (EPO is able to stimulate angiogenesis and mitosis, activating vascularization and cell cycle. The aim of our study was to investigate whether two biosimilar recombinant human erythropoietins, EPO-α and EPO-Z, may promote these processes in an experimental model of burn injury. A total of 84 mice were used and a scald burn was produced on the back after shaving, in 80°C water for 10 seconds. Mice were then randomized to receive EPO-α (400 units/kg/day/sc or EPO-Z (400 units/kg/day/sc or their vehicle (100 μL/day/sc 0.9% NaCl solution. After 12 days, both EPO-α and EPO-Z increased VEGF protein expression. EPO-α caused an increased cyclin D1/CDK6 and cyclin E/CDK2 expression compared with vehicle and EPO-Z (p<0.001. Our study showed that EPO-α and EPO-Z accelerated wound closure and angiogenesis; however EPO-α resulted more effectively in achieving complete skin regeneration. Our data suggest that EPO-α and EPO-Z are not biosimilars for the wound healing effects. The higher efficacy of EPO-α might be likely due to its different conformational structure leading to a more efficient cell proliferation and skin remodelling.

    Deep second-degree burns are characterized by delayed formation of granulation tissue and impaired angiogenesis. Erythropoietin (EPO) is able to stimulate angiogenesis and mitosis, activating vascularization and cell cycle. The aim of our study was to investigate whether two biosimilar recombinant human erythropoietins, EPO-α and EPO-Z, may promote these processes in an experimental model of burn injury. A total of 84 mice were used and a scald burn was produced on the back after shaving, in 80°C water for 10 seconds. Mice were then randomized to receive EPO-α (400 units/kg/day/sc) or EPO-Z (400 units/kg/day/sc) or their vehicle (100 μL/day/sc 0.9% NaCl solution). After 12 days, both EPO-α and EPO-Z increased VEGF protein expression. EPO-α caused an increased cyclin D1/CDK6 and cyclin E/CDK2 expression compared with vehicle and EPO-Z (p<0.001). Our study showed that EPO-α and EPO-Z accelerated wound closure and angiogenesis; however EPO-α resulted more effectively in achieving complete skin regeneration. Our data suggest that EPO-α and EPO-Z are not biosimilars for the wound healing effects. The higher efficacy of EPO-α might be likely due to its different conformational structure leading to a more efficient cell proliferation and skin remodelling.

  11. [Treatment of pain in children burns]. (United States)

    Latarjet, J; Pommier, C; Robert, A; Comparin, J P; Foyatier, J L


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

  14. Comparison of measures of physiologic stress during treadmill exercise in a patient with 20% lower extremity burn injuries and healthy matched and nonmatched individuals. (United States)

    Wetzel, J L; Giuffrida, C; Petrazzi, A; Schlanser, J; McDowell-Montini, C; Pietrzyk, C; Landry, V L


    Patients with burn injuries are referred for rehabilitation within days after the injuries to encourage early ambulation and functional training. Many of these patients are hypermetabolic at rest. Metabolic demands of activity are added to the already hypermetabolic state and elevate total energy requirements and some physiologic measures. Reports on the physiologic stress imposed by therapeutic activities for patients with burn injuries are limited to low levels of metabolic demand (burn injuries. The purpose of this study was to report the clinical measures of myocardial and physiologic stress in a patient with 20% lower extremity total body surface area burns during an exercise challenge equivalent to stair climbing. Physiologic measures were assessed before and during a treadmill activity (5 METS) for a 40-year-old obese man 3 weeks after he had lower extremity burn injuries. These measures were compared with mean values for 62 healthy counterparts and 6 healthy subjects matched for age, gender, and fitness level. Heart rate, systolic blood pressure, rate pressure product, and the rating of perceived exertion for the patient with burn injuries were higher at baseline and during exercise than the mean values for the 62 healthy individuals and the 6 matched subjects. The steady state exercise values for heart rate, systolic blood pressure, rate pressure product, and rating of perceived exertion at 6 minutes were 189 beats per minute, 190 mm Hg, 3591, and 17, respectively, for the patient with burn injuries and were 111.3 beats per minute, 149 mm Hg, 1680, and 11.7, respectively, for the 6 matched subjects. Ventilation during exercise also increased for the patient with burn injuries more than for the matched subjects (3/4 vs 1/4). Pain experienced by the patient with burn injuries decreased with activity (9.8 vs 7.3 on a 15-cm scale). Treadmill walking produced near maximal responses for most physiologic measures for this patient who was hypermetabolic at rest

  15. Changes to oak woodland stand structure and ground flora composition caused by thinning and burning (United States)

    Kinkead, Carter O.; Kabrick, John M.; Stambaugh, Michael C.; Grabner, Keith W.


    Our objective was to quantify the cumulative effects of prescribed burning and thinning on forest stocking and species composition at a woodland restoration experiment site in the Ozark Highlands of Missouri. Our study used four treatments (burn, harvest, harvest and burn, control) on three slope position and aspect combinations (south, north, ridge) replicated in three complete blocks. Harvested stands were thinned from below to 40 percent residual stocking. Two prescribed fires were applied to both burn and harvest-burn treatment units in a 5-year period. Results reflect changes that have taken place over a 6-year period, from pretreatment conditions to 1 year after the last fire. In this period, there was a 10-percent reduction in the stocking in burned stands compared to control and a 6-percent reduction in harvested and burned stands compared to harvested stands. Compared to the control, percentage ground cover of woodland indicators was seven times greater in burned stands, six times greater in harvested stands, and 22 percent greater in harvested and burned stands. Th ere was no significant (P > 0.05) interaction between aspect and treatment on stocking or ground flora cover. Th is study indicated that silvicultural treatments do achieve various goals that are common to managers who aim to restore woodland communities.

  16. Assessment of Oro-Maxillofacial Trauma According to Gender, Age, Cause and Type of the Injury (United States)

    Matijević, Marko; Sikora, Miroslav; Leović, Dinko; Mumlek, Ivan; Macan, Darko


    Objectives The occurrence and causes of maxillofacial trauma varies in different regions of the world. The aim of this study was to identify the occurrence, types and causes of maxillofacial injuries according to the age and gender differences in patients treated at the Department of Maxillofacial Surgery, University Hospital Center Osijek, between January 2011 and December 2013. Materials and methods A total of 64 patients, 41 males (64.1%) and 23 females (35.9%), aged from 18 to 86 years (mean age 42) participated in the study. Data collected and analyzed included gender, age, cause of injury and the type of maxillofacial injuries. Results The most common cause of injuries in both gender groups was falling down (39% males; 65% females). The second leading cause of injuries in males was interpersonal violence (29%) and in females traffic accident (26%) (p0.05). The most common causes of injuries in the youngest patients was violence (43%), and in others fall (50-70%; p0.05). The majority of the falls and violence caused bone tissue injuries, and soft tissue and dentalveolar injuries were detected in traffic and sports accidents (p>0.05). Conclusion Falling down was the most common cause of oro-maxillofacial injuries in both men and women and in all three age groups. The leading type of injury was bone injury. The data obtained from this study provide important information for future prevention from injuries. PMID:27688419

  17. Effects of a 12-wk resistance exercise program on skeletal muscle strength in children with burn injuries. (United States)

    Suman, O E; Spies, R J; Celis, M M; Mlcak, R P; Herndon, D N


    The posttraumatic response to burn injury leads to marked and prolonged skeletal muscle catabolism and weakness, which persist despite standard rehabilitation programs of occupational and physical therapy. We investigated whether a resistance exercise program would attenuate muscle loss and weakness that is typically found in children with thermal injury. We assessed the changes in leg muscle strength and lean body mass in severely burned children with >40% total body surface area burned. Patients were randomized to a 12-wk standard hospital rehabilitation program supplemented with an exercise training program (n = 19) or to a home-based rehabilitation program without exercise (n = 16). Leg muscle strength was assessed before and after the 12-wk rehabilitation or training program at an isokinetic speed of 150 degrees /s. Lean body mass was assessed using dual-energy X-ray absorptiometry. We found that the participation in a resistance exercise program results in a significant improvement in muscle strength, power, and lean body mass relative to a standard rehabilitation program without exercise.

  18. Central activation of TRPV1 and TRPA1 by novel endogenous agonists contributes to mechanical allodynia and thermal hyperalgesia after burn injury. (United States)

    Green, Dustin; Ruparel, Shivani; Gao, Xiaoli; Ruparel, Nikita; Patil, Mayur; Akopian, Armen; Hargreaves, Kenneth


    The primary complaint of burn victims is an intense, often devastating spontaneous pain, with persistence of mechanical and thermal allodynia. The transient receptor potential channels, TRPV1 and TRPA1, are expressed by a subset of nociceptive sensory neurons and contribute to inflammatory hypersensitivity. Although their function in the periphery is well known, a role for these TRP channels in central pain mechanisms is less well defined. Lipid agonists of TRPV1 are released from peripheral tissues via enzymatic oxidation after burn injury; however, it is not known if burn injury triggers the release of oxidized lipids in the spinal cord. Accordingly, we evaluated whether burn injury evoked the central release of oxidized lipids . Analysis of lipid extracts of spinal cord tissue with HPLC-MS revealed a significant increase in levels of the epoxide and diol metabolites of linoleic acid: 9,10-DiHOME, 12,13-DiHOME, 9(10)-EpOME, and 12(13)-EpOME, that was reduced after intrathecal (i.t.) injection of the oxidative enzyme inhibitor ketoconazole. Moreover, we found that these four lipid metabolites were capable of specifically activating both TRPV1 and TRPA1. Intrathecal injection of specific antagonists to TRPV1 (AMG-517) or TRPA1 (HC-030031) significantly reduced post-burn mechanical and thermal allodynia. Finally, i.t. injection of ketoconazole significantly reversed post-burn mechanical and thermal allodynia. Our data indicate that spinal cord TRPV1 and TRPA1 contributes to pain after burn and identifies a novel class of oxidized lipids elevated in the spinal cord after burn injury. Since the management of burn pain is problematic, these findings point to a novel approach for treating post-burn pain.

    Sunbed exposure frequently leads to erythema of the skin but second-degree burns are unusual. We report two patients who experienced second-degree burns due to partial displacement of the filter in the facial tanner of a sunbed. This is a severe fault and calls for increased safety regulations....

  1. Smoked marijuana as a cause of lung injury. (United States)

    Tashkin, D P


    In many societies, marijuana is the second most commonly smoked substance after tobacco. While delta9-tetrahydrocannabinol (THC) is unique to marijuana and nicotine to tobacco, the smoke of marijuana, like that of tobacco, consists of a toxic mixture of gases and particulates, many of which are known to be harmful to the lung. Although far fewer marijuana than tobacco cigarettes are generally smoked on a daily basis, the pulmonary consequences of marijuana smoking may be magnified by the greater deposition of smoke particulates in the lung due to the differing manner in which marijuana is smoked. Whereas THC causes modest short-term bronchodilation, regular marijuana smoking produces a number of long-term pulmonary consequences, including chronic cough and sputum, histopathologic evidence of widespread airway inflammation and injury and immunohistochemical evidence of dysregulated growth of respiratory epithelial cells, that may be precursors to lung cancer. The THC in marijuana could contribute to some of these injurious changes through its ability to augment oxidative stress, cause mitochondrial dysfunction, and inhibit apoptosis. On the other hand, physiologic, clinical or epidemiologic evidence that marijuana smoking may lead to chronic obstructive pulmonary disease or respiratory cancer is limited and inconsistent. Habitual use of marijuana is also associated with abnormalities in the structure and function of alveolar macrophages, including impairment in microbial phagocytosis and killing that is associated with defective production of immunostimulatory cytokines and nitric oxide, thereby potentially predisposing to pulmonary infection. In view of the growing interest in medicinal marijuana, further epidemiologic studies are needed to clarify the true risks of regular marijuana smoking on respiratory health.

  3. Two cases of burns caused by misuse of coagulation unit and monitoring. (United States)

    Rolly, G


    Two cases of severe burns with monitoring apparatus are described. In a female patient of 45 years, a severe third degree burn occurred by misuse of coagulation apparatus (inversion of the poles of an older Bovie apparatus), in the presence of a non-floating ECG monitoring device. A high intensity current was established from the coagulation unit, via the earth plate under the buttocks, to the indifferent electrode placed on the chest, where burns occurred. In an 8 month female baby, having laparotomy for a neuroblastoma, a third degree burn of 5 cm diameter occurred with a non-floating ECG monitor. A twin-wired disposable earth plate was placed just beneath the indifferent ECG electrode on the leg. A burning current was established between the Bovie coagulation unit and the monitor.

  4. The Effects of Alcohol Intoxication and Burn Injury on the Expression of Claudins and Mucins in the Small and Large Intestines. (United States)

    Hammer, Adam M; Khan, Omair M; Morris, Niya L; Li, Xiaoling; Movtchan, Nellie V; Cannon, Abigail R; Choudhry, Mashkoor A


    Alcohol intoxication at the time of burn injury exacerbates postburn pathogenesis. Recent findings suggest gut barrier integrity is compromised after combined alcohol and burn insult, which could contribute to these complications. Tight junction proteins and mucins play critical roles in keeping the gut barrier intact. Therefore, the goal of this study was to examine the effects of alcohol and burn injury on claudin and mucin expression in the intestines. We also evaluated if the combined insult differentially influences their expression in the small and large intestines. Male C57BL/6 mice were given a single dose of 2.9 g/kg ethanol before an approximately 12.5% body area burn. One and three days after injury, we profiled expression of several tight junction proteins, mucin, and bacterial 16S rRNA genes in the small and large intestines, using qPCR. We observed >50% decrease in claudin-4 and claudin-8 genes in both ileal and colonic epithelial cells 1 day after injury. Claudin-2 was significantly upregulated, and occludin was downregulated in the small intestine 1 day after injury. Mucin-3 expression was substantially elevated (>50%) in the small intestine, whereas mucin-2 and mucin-4 were considerably diminished in the colon (>50%) 1 day after injury. Most of the parameters were normalized to sham levels on day 3, except for mucin-3 and claudin-8, which remained decreased in the large intestine. Neither alcohol nor burn alone resulted in changes in junction or mucin gene expression compared to shams. This was accompanied with increases in the family of Gram-negative bacteria, Enterobacteriaceae, in both the small and the large intestines 1 day after injury. These findings suggest that alcohol and burn injury disrupts the normal gut microbiota and alters tight junction and mucin expression in the small and large intestines.

    Objective: To introduce a safe and specific approachof 13C magnetic resonance spectrum (13C MRS )spectroscopy and investigate the alterations in hepaticanabolism.Methods: Relative anaplerotic, pyruvate recyclingand gluconeogenic fluxes were measured by 13C MRSisotopomer analysis of blood glucose from rats with 40%body surface area burn injury, and from rats exposed tosham injury. A short chain fatty acid, [U-13C] propionatewhich was avidly extracted by the liver, was infusedintravenously to deliver 13C into the citric acid cycle.Proton-decoupled 13C MRS of deproteinized plasma orextracts of the freeze-clamped liver were used to determinethe distribution of 13C in blood or hepatic glucose.Results: There was no difference in the multipletsdetected in the glucose carbon-2 anomer from blood or liverafter 45 or 60 minutes of the infusion of the propionate,indicating that steady-state isotopic conditions wereachieved. Gluconeogenesis relative to citric acid cycle fluxwas not altered by burn injury; in both sham and burngroups the rate of glucose production was about equal toflux through citrate synthase. In the sham group ofanimals, the rate of entry of carbon skeletons into the citricacid cycle was about 4 times than that in the burn group.Similarly, flux through pyruvate kinase (again relative tocitrate synthase) was significantly increased after the burninjury.Conclusions: Since results from analysis of the bloodglucose are the same as that of the hepatic glucose, 13Cdistribution in the glucose and hepatic metabolism can beassessed based on the 13C MRS analysis of the bloodglucose.

  7. Current situation and reflection on rehabilitation after burn injury in China%中国烧伤康复治疗的现状与思考

    Institute of Scientific and Technical Information of China (English)

    吴军; 陈建


    After over 50 years'development,the modern burn care system of China has made remarkable progress,however,we still lack ample attention to functional rehabilitation and quality of life of burn patients recovering from burn injury.The burn rehabilitation in China is still in juvenile stage,but it is really encouraging that more and more burn care facilities are paying attention to it.To further promote the development of burn rehabilitation in China,more emphasis must be stressed on the formation of multidisciplinary team in our burn care system,the concept of early and integral rehabilitation should be promoted,and therapeutic regimens and research work on function and aesthetics related body parts like hand and face should be emphasized.Moreover,we should also carry out rehabilitation on pediatric burn patients and promulgate the idea of burn rehabilitation in the society at large with the purpose of seeking supports for burn rehabilitation from all sectors of the society.

  8. Patterns of maxillofacial injuries caused by terrorist attacks in Iraq: retrospective study. (United States)

    Gataa, I S; Muassa, Q H


    Over the past 5 years, Iraq has witnessed daily terrorist attacks mainly using improvised explosive devices. The aim of this study was to analyze the patterns of maxillofacial injuries caused by terrorist attacks in a sample of Iraqi casualties. Records from two hospitals, including 551 patients who sustained maxillofacial injuries due to terrorists attacks, were analyzed according to the patients' age, sex, site of injury, type of injury and cause of injury. Concomitant injuries and mortality were also considered. The most common age group affected was those aged 15-29 years. Most of these injuries were caused by improvised explosive devices (71%). More than one facial zone was injured in 212 patients (38%). Isolated soft tissues injuries were detected in (54%) of victims. Pure maxillofacial injuries comprised 33%. The most common injuries associated with this type of trauma were eye injuries (29%). The mortality rate was 2% from pure maxillofacial injuries. Terrorist attacks cause unique maxillofacial injuries, which should be considered a new entity in the trauma field.

  9. How to manage burns in primary care.


    Waitzman, A. A.; Neligan, P. C.


    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.

  10. Increased poly(ADP-ribosyl)ation in skeletal muscle tissue of pediatric patients with severe burn injury: prevention by propranolol treatment. (United States)

    Oláh, Gábor; Finnerty, Celeste C; Sbrana, Elena; Elijah, Itoro; Gerö, Domokos; Herndon, David N; Szabó, Csaba


    Activation of the nuclear enzyme poly(ADP-ribose) polymerase (PARP) has been shown to promote cellular energetic collapse and cellular necrosis in various forms of critical illness. Most of the evidence implicating the PARP pathway in disease processes is derived from preclinical studies. With respect to PARP and burns, studies in rodent and large animal models of burn injury have demonstrated the activation of PARP in various tissues and the beneficial effect of its pharmacological inhibition. The aims of the current study were to measure the activation of PARP in human skeletal muscle biopsies at various stages of severe pediatric burn injury and to identify the cell types where this activation may occur. Another aim of the study was to test the effect of propranolol (an effective treatment of patients with burns) on the activation of PARP in skeletal muscle biopsies. Poly(ADP-ribose) polymerase activation was measured by Western blotting for its product, poly(ADP-ribose) (PAR). The localization of PARP activation was determined by PAR immunohistochemistry. The results showed that PARP becomes activated in the skeletal muscle tissue after burns, with the peak of the activation occurring in the middle stage of the disease (13-18 days after burns). Even at the late stage of the disease (69-369 days after burn), an elevated degree of PARP activation persisted in some of the patients. Immunohistochemical studies localized the staining of PAR primarily to vascular endothelial cells and occasionally to resident mononuclear cells. There was a marked suppression of PARP activation in the skeletal muscle biopsies of patients who received propranolol treatment. We conclude that human burn injury is associated with the activation of PARP. We hypothesize that this response may contribute to the inflammatory responses and cell dysfunction in burns. Some of the clinical benefit of propranolol in burns may be related to its inhibitory effect on PARP activation.

  12. The challenges of dysphagia management and rehabilitation after extensive thermal burn injury: a complex case. (United States)

    Rumbach, Anna F; Ward, Elizabeth C; Cornwell, Petrea L; Bassett, Lynell V; Muller, Michael J


    The role of the speech pathologist in the burns population is still emerging, with detailed discussion of the assessment and management of dysphagia limited to date. This report describes the case of a 60-year-old man who developed severe contractures of the head and neck and oropharyngeal dysphagia after sustaining 53.5% deep partial- and full-thickness burns. Although some aspects of rehabilitation were confounded by a preexisting mild intellectual disability, the patient was able to participate in an intensive regimen of active and passive exercise to rehabilitate his oropharyngeal dysphagia. Significant oral contractures remained; however, the patient was discharged without tracheostomy and consuming a texture-modified diet with no signs of aspiration. To our knowledge, this is one of a small handful of reports that document speech pathology management of the burns population, and a first that identifies and outlines specific characteristics of, and rehabilitation strategies for, dysphagia in a burned individual.

  13. Oro-facial thermal injury caused by food heated in a microwave oven. (United States)

    Wakefield, Yasha; Pemberton, Michael N


    Burns to the oral mucosa usually result from the accidental ingestion of hot food or beverages. The burns are usually of short duration and little consequence. The widespread use of microwave ovens, however, has added a new dimension to the problem. Microwave ovens heat food much quicker than a conventional oven, but they produce uneven heating within the food and extremely high temperatures can be reached. We describe two cases of patients who suffered inadvertent injury to the oral mucosa from the ingestion of microwave-heated food.

  14. Burn and cut injuries related to job stress among kitchen workers in Japan. (United States)

    Haruyama, Yasuo; Matsuzuki, Hiroe; Tomita, Shigeru; Muto, Takashi; Haratani, Takashi; Muto, Shigeki; Ito, Akiyoshi


    To clarify the correlation between kitchen work-related burns and cuts and job stress, a self-administered questionnaire survey was conducted involving 991 kitchen workers among 126 kitchen facilities. The demographics, condition of burns and cuts, job stress with the Brief Job Stress Questionnaire (BJSQ), health condition, and work-related and environmental factors were surveyed. Multiple logistic regression models and trend tests were used according to quartiles (Q1, Q2, Q3, and Q4) of each sub-scale BJSQ. After adjustment for potential confounding variables, burns/cuts were associated with a higher score category (Q4) of job demands (OR: 2.56, 95% CI: 1.10-6.02/OR: 2.72, 95% CI: 1.30-5.69), psychological stress (OR: 4.49, 95% CI: 2.05-9.81/OR: 3.52, 95% CI: 1.84-6.72), and physical stress (OR: 2.41, 95% CI: 1.20-4.98/OR 2.16, 95% CI: 1.16-4.01). The ORs of the burn/cut injures increased from Q1 to Q4 with job demands (p for trend = 0.045/0.003), psychological stress (p for trendkitchen work-related burns and cuts are more likely to be correlated with job stress, and the higher the job stress score, the higher the frequency of burns and cuts among kitchen workers.

    Trauma to soft tissues is an important consideration in cases of seatbelt injury, as soft-tissue injury can cause shock. Careful observation for hours in the clinic at least, along with appropriate imaging studies, is necessary if signs of a seatbelt injury exist.

  16. Penetrating injury of the lungs and multiple injuries of lower extremities caused by aircraft bombs splinters

    Directory of Open Access Journals (Sweden)

    Golubović Zoran


    Full Text Available Introduction. Injuries caused by aircraft bombs cause severe damages to the human body. They are characterized by massive destruction of injured tissues and organs, primary contamination by polymorph bacterial flora and modified reactivity of the body. Upon being wounded by aircraft bombs projectiles a victim simultaneously sustains severe damages of many organs and organ systems due to the fact that a large number of projectiles at the same time injure the chest, stomach, head and extremities. Case report. We presented a patient, 41 years of age, injured by aircraft bomb with hemo-pneumothorax and destruction of the bone and soft tissue structures of the foot, as well as the treatment result of such heavy injuries. After receiving thoracocentesis and short reanimation, the patient underwent surgical procedure. The team performed thoracotomy, primary treatment of the wound and atypical resection of the left lung. Thoracic drains were placed. The wounds on the lower leg and feet were treated primarily. Due to massive destruction of bone tissue of the right foot by cluster bomb splinters, and impossibility of reconstruction of the foot, guillotine amputation of the right lower leg was performed. Twelve days after the wounding caused by cluster bomb splinters, soft tissue of the left lower leg was covered by Tirsch free transplantant and the defect in the area of the left foot was covered by dorsalis pedis flap. The transplant and flap were accepted and the donor sites were epithelized. Twenty-six days following the wounding reamputation was performed and amputation stump of the right lower leg was closed. The patient was given a lower leg prosthesis with which he could move. Conclusion. Upon being wounded by aircraft bomb splinters, the injured person sustains severe wounds of multiple organs and organ systems due to simultaneous injuries caused by a large number of projectiles. It is necessary to take care of the vital organs first because they

  17. What could have caused pre-industrial biomass burning emissions to exceed current rates?

    Directory of Open Access Journals (Sweden)

    G. R. van der Werf


    Full Text Available Recent studies based on trace gas mixing ratios in ice cores and charcoal data indicate that biomass burning emissions over the past millennium exceeded contemporary emissions by up to a factor of 4 for certain time periods. This is surprising because various sources of biomass burning are linked with population density, which has increased over the past centuries. Here we have analyzed how emissions from several biomass burning sources could have fluctuated to yield emissions that are in correspondence with recent results based on ice core mixing ratios of carbon monoxide (CO and its isotopic signature measured at South Pole station (SPO. Based on estimates of contemporary fire emissions and the TM5 chemical transport model, we found that CO mixing ratios at SPO are more sensitive to emissions from South America and Australia than from Africa, and are relatively insensitive to emissions from the Northern Hemisphere. We then explored how various biomass burning sources may have varied over the past centuries and what the resulting emissions and corresponding CO mixing ratio at SPO would be, using population density variations to reconstruct sources driven by humans (e.g. fuelwood burning and a new model to relate savanna emissions to changes in fire return times. We found that to match the observed ice core CO data all savannas in the Southern Hemisphere had to burn annually, or bi-annually in combination with deforestation and slash and burn agriculture matching current levels despite much lower population densities and lack of machinery to aid the deforestation process. While possible, these scenarios are unlikely and in conflict with current literature. However, we do show the large potential for increased emissions from savannas in a pre-industrial world. This is mainly because in the past, fuel beds were probably less fragmented compared to the current situation; we show that the majority of savannas have not burned in the past 10 yr, even

  18. Bone marrow-derived myofibroblasts recruited to the upper dermis appear beneath regenerating epidermis after deep dermal burn injury. (United States)

    Yamaguchi, Ryo; Takami, Yoshihiro; Yamaguchi, Yoshihiro; Shimazaki, Syuji


    Fibroblasts and myofibroblasts migrating to sites of tissue repair after injury may not only be locally recruited but could also be recruited from the bone marrow. However, the characteristics and functional roles, if any, of these cells in wound healing are poorly understood. Here, we show unequivocally that bone marrow-derived fibroblasts do contribute to deep dermal burn wound healing. Bone-marrow stromal cells were collected from femurs of male Lewis rats, cultured for a week, and then the adherent cells were labeled with the fluorescent marker PKH-26. These cells stained positive for alpha-smooth muscle actin and prolyl 4-hydroxylase, but did not express RM-4 (a macrophage marker), CD34, or cytokeratin, characteristic of myofibroblastic differentiation. When injected intravenously into Lewis rats, they homed to the bone marrow. Five days after transplantation, a deep dermal burn was made on the back of the rat, and biopsies were taken 7, 10, and 14 days later. PKH-positive cells were not found at day 7, but by day 10, they were easily detected mainly in the upper dermis close beneath the regenerating epidermis. These PKH-positive cells still stained for alpha-SMA and prolyl 4-hydroxylase, but not RM4. Thus, it is suggested that myofibroblasts originating in the bone marrow contribute not only to promotion of granulation but also enhancement of dermal-epidermal interaction after thermal injury.

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

    Chronic cold exposure induces functionally thermogenic mitochondria in the inguinal white adipose tissue (iWAT) of mice. Whether this response occurs in pathophysiological states remains unclear. The purpose of this study was to determine the impact of severe burn trauma on iWAT mitochondrial function in mice. Male BALB/c mice (10-12 weeks) received full-thickness scald burns to ∼30% of the body surface area. Inguinal white adipose tissue was harvested from mice at 1, 4, 10, 20, and 40 days postinjury. Total and uncoupling protein 1 (UCP1)-dependent mitochondrial thermogenesis were determined in iWAT. Citrate synthase activity was determined as a proxy of mitochondrial abundance. Immunohistochemistry was performed to assess iWAT morphology and UCP1 expression. Uncoupling protein 1-dependent respiration was significantly greater at 4 and 10 days after burn compared with sham, peaking at 20 days after burn (P white adipose tissue in vivo and may offer a mechanistic explanation for the chronic hypermetabolism observed in burn victims.

    Objective To investigate the expression sequence and distribution characteristics of the protooncogenes c-fos, c-myc and endogenous basic fibroblast growth factor (bFGF ) genes in burned tissues, and to explore the possible effects of changes in the se genes' functions on wound healing. Methods Partial-thickness burns of 30% TBSA were established on backs of Wistar rats. Insitu hybridization and histological methods were used to detect expression of c-fos, c-myc and bFGF genes in normal and burned tissue at 3 h, 6 h, 1 d, 3 d , 7 d and 14 d postburn. Results Although expression of c-fos and c-myc genes and bFGF gene could be found in normal skin, the expression of all three were markedly induced by burn wounds and the expression models in sequence and distribution were quite different. Expre ssion of c-fos gene increased and peaked at 6 h. Signals were mainly localiz ed in both nuclei of dermal fibroblasts and monocytes. The expression of bFGF gene increased at 6 h and peaked at 1 d postburn, and was distributed in the cyt oplasm of fibroblasts. C-myc gene peaked 3 d postburn and was also distributed in the cytoplasm of fibroblasts. Conclusions These results indicated that thermal injury could induce the expression of c-fos, c-myc and bFGF at gene level, showing phasic control and regional distributi on. The phasic expression of these genes suggests that there is an interaction between protooncogenes and bFGF, which may play an important role in wound heali ng. The different expressions of c-fos and c-myc play an inducing role in reg ulating bFGF, and in turn affect wound healing.

  5. Rehabilitation of the burn patient

    Directory of Open Access Journals (Sweden)

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

    Determination of the age of burns, as well as of wounds induced mechanically, is essential in forensic practice, particularly in cases of suspected child abuse. Here, we investigated temporal changes in the expression of 13 genes during wound healing after a burn. The expression of cytokines (IL-1β, IL-6, IL-10, TNF-α, and IFN-γ), chemokines (KC, MCP-1), proliferative factors (TGF-β, VEGF), proteases (MMP-2, 9, 13) and type I collagen in murine skin was examined by real-time PCR at 3, 6, 9, and 12 h and 1, 2, 3, 5, 7, and 14 days after a burn. Based on macroscopic and histological appearance, the healing process of a burn consists of 3 phases: inflammatory (from 3 h to 1 day after the burn), proliferative (from 1 to 7 days), and maturation (from 7 to 14 days). Expression of IL-1β, IL-6, TNF-α, IFN-γ and KC increased significantly in a biphasic pattern from 3 or 6 h to 12 h or 1 day and from 3 or 5 days to 7 days. Expression of MCP-1 increased significantly from 6 h to 5 days. Expression of both IL-10 and TGF-β increased significantly from 12 h to 7 days. Expression of VEGF, MMP-2, MMP-13 and type I collagen increased significantly from 3 days to 7 or 14 days. Expression of MMP-9 increased significantly from 6 h to 14 days. Our results suggest that evaluating the expression of a combination of these genes would enable the exact estimation of the age of a burn.

  7. Long hair, smoking, and deep facial burns. (United States)

    Koljonen, Virve


    The purpose of this article is to describe deep facial burn injuries by cigarette lighters in longhaired adults and to report our experience in their treatment. Eight consecutive cigarette lighter burn victims are treated in the Helsinki Burn Center in the year 2006. Seven of the patients were women; their mean age was 50 years. All were under the influence of alcohol at the time of injury. The mean burnt area was 3.5% TBSA. The burnt areas were primarily forehead, cheek, and ipsilateral ear. After a conservative treatment, all the patients underwent an operation, whereby the nonhealing burns were excised and covered with autologous split thickness skin grafts. Postoperative period was uneventful in all the patients. Besides having severe detrimental effects on general health status and wound healing, smoking is the leading cause of residential and total fire deaths worldwide. The patients in this article suffered deep facial burns because of cigarette lighters.

    CHEN Zhong-yong; WANG Shi-liang; YU Bin; LI Ao


    To assess the clinical effects ofenteral nutrition on intestinal structure and function in the early stage of severe burns. Methods: Nineteen cases of severe burn injury were divided randomly into enteral nutrition group (EN) and parenteral nutrition group (PN). Gastrin, motilin, malondialdehyde (MDA), superoxide dismutase (SOD), endotoxin, rumor necrosis (TNF), diamine oxidase (DAO) and lactulose/mannitol (L/M) were determined on postburn day 1, 4, 8, 14 (PBD) respectively. Results: Serum gastrin and motilin on PBD 4 and 8 were significantly higher in EN group than in PN group (P<0.05-0.01). Plasma MDA on PBD4 and PBD8 was obviously lower in EN group than in PN group (P<0.01). Plasma SOD on PBD4 and PBD8 was significantly higher in EN group than in PN group (P<0.01). At the most time points, endotoxin and TNF were significantly lower in EN group than in PN group (P<0.01). Serum DAO tended to decrease in EN group, and on PBD4 it was obviously lower in EN group than in PN group (P<0.01). Gut permeability L/M on PBD4, PBD8 was obviously in EN group lower than in PN group (P<0.05-0.01). There was positive correlation between L/M and DAO, and between MDA and TNF (P<0.05-0.01), and negative correlation between L/M and SOD (P<0.01). Conclusion: On the basis of the findings, it is considered that the early enteral nutrition is more effective to preserve the secretion and motility of gastrointestinal tract, decrease intestinal ischemia and reperfusion injury, reduce intestinal permeability, decrease plasma endotoxin and mediators,and maintain mucosa barrier function. Enteral nutrition is superior to parenteral nutrition in the early stage of severe bum injury.

  9. Living with burn scars caused by self-immolation among women in Iraqi Kurdistan: A qualitative study. (United States)

    Mirlashari, Jila; Nasrabadi, Alireza Nikbakht; Amin, Pakestan Mohammad


    Patients with burns have to live with a variety of long-term physical and psychosocial consequences. Burns lead to prolonged hospital stay, disfiguring scars, disability, and even death. Since self-immolation is common in women of Iraqi Kurdistan, the present study sought to explore the experiences of women living with scars caused by self-immolation. This paper was part of a qualitative research study. A purposive sample of 18 female self-immolation survivors from Iraqi Kurdistan was selected, and 21 individual interviews were conducted and analyzed using conventional content analysis. Four categories emerged during the data analysis: (1) feelings of disbelief, regret, and anger caused by post-burn scars; (2) desperately seeking solutions; (3) grief due to disappointment and surrender to despair; and (4) rejection and isolation. In conclusion, individuals with scars and disfigurements sometimes adopted inappropriate measures to deal with the psychological problems caused by others' behaviors and wrong perceptions. Educational and support programs are hence indicated to promote awareness levels of self-immolation survivors, their families, and the whole society.

    Asquith, Catherine; Kimble, Roy; Stockton, Kellie


    The aim of this study was to quantify and describe the characteristics of burns in children caused by sun heated surfaces. Children presenting between January 2013 and February 2014 with a burn due to sun heated surfaces were included in the study. Fifteen children were identified representing 1.7% of new burns. The mean age was 18.3 months. All burns occurred during the warmer months between 11a.m. and 4p.m. and the feet were commonly involved. Most cases occurred in the child's home garden but six cases occurred in public play areas. Metal was the most common surface involved. Most burns were superficial partial thickness with two burns deep dermal partial thickness and one child needed a skin graft. Burns due to sun heated surfaces are relatively frequent. Parents need to be aware that in summer surfaces can become hot enough to cause burns to bare feet in young children. Play areas need to be shaded or covered in surfaces that do not become hot enough to cause burns and metal objects should not be left in the sun in children's play areas.

  15. Phytocontact Dermatitis due to Mustard Seed Mimicking Burn Injury: Report of a Case

    Directory of Open Access Journals (Sweden)

    Hakan Yabanoglu


    Full Text Available Mustard seeds have been used in traditional folk medicine as a stimulant, diuretic, and purgative and to treat a variety of ailments including peritonitis and neuralgia. Mustards are still used today in mustard plasters to treat rheumatism, arthritis, chest congestion, aching back, and sore muscles. To make a mustard plaster, mix equal parts of flour and powdered mustard and spread it as a paste on a doubled piece of soft cloth. Apply mustard plaster to the affected area for a maximum of 15 minutes. Prolonged application can result in burns to the skin and nerve damage. Skin lesions occur within hours after exposure, and there is no significant therapy procedure. This case report is about a patient with second-degree burn, occurred when a mixture including mustard seed was exposed to her skin in the pain therapy of the osteoarthritis in her left knee. There are no studies analyzing treatment of skin burns induced by mustard seed in the literature. While in this type of burns our experience is limited, we think that conservative approach should be first choice of treatment.

  17. Contribution of gene expression to metabolic fluxes in hypermetabolic livers induced through burn injury and cecal ligation and puncture in rats. (United States)

    Banta, Scott; Vemula, Murali; Yokoyama, Tadaaki; Jayaraman, Arul; Berthiaume, François; Yarmush, Martin L


    Severe injury activates many stress-related and inflammatory pathways that can lead to a systemic hypermetabolic state. Prior studies using perfused hypermetabolic rat livers have identified intrinsic metabolic flux changes that were not dependent upon the continual presence of elevated stress hormones and substrate loads. We investigated the hypothesis that such changes may be due to persistent alterations in gene expression. A systemic hypermetabolic response was induced in rats by applying a moderate burn injury followed 2 days later by cecum ligation and puncture (CLP) to produce sepsis. Control animals received a sham-burn followed by CLP, or a sham-burn followed by sham-CLP. Two days after CLP, livers were analyzed for gene expression changes using DNA microarrays and for metabolism alterations by ex vivo perfusion coupled with Metabolic Flux Analysis. Burn injury prior to CLP increased fluxes while decreases in gene expression levels were observed. Conversely, CLP alone significantly increased metabolic gene expression, but decreased many of the corresponding metabolic fluxes. Burn injury combined with CLP led to the most dramatic changes, where concurrent changes in fluxes and gene expression levels occurred in about 1/3 of the reactions. The data are consistent with the notion that in this model, burn injury prior to CLP increased fluxes through post-translational mechanisms with little contribution of gene expression, while CLP treatment up-regulated the metabolic machinery by transcriptional mechanisms. Overall, these data show that mRNA changes measured at a single time point by DNA microarray analysis do not reliably predict metabolic flux changes in perfused livers.

    Institute of Scientific and Technical Information of China (English)



    Objective To explore the characteristic and treatment of the severe head injury due to motorcycle accident.Methods Review and analysis of 27 motorcycle traffic trauma cases who were admitted to our hospital from Oct.1995 to Sep.1997.Results Young men were the main composition of these patients.Multiple injuries associated with brain ste or diffuse axonal injury were common,which were the main factors influencing the consciousness and prognosis of the patients.The wound was usually severely contaminated.Evacuation of hematomas,decompression by depleting skull flap,hypotheymia and artificial hibernation were conducted in this series.Among them,14 cases were cured ,3 cases were seriously disabled,10 cases died.Conclusions Motorcycle's weight is light so it easily loses its balance.The riders and the passengers are exposed and lack protection.Driving against traffic regulations is frquently seen.All these are the reasons why the motorcycle traffic accidents often take place. When the traffic accident happens,the patients' head generally is thrown a long distance and dashed against the barrier or the ground.The psture nd mechanism of injury were complicated and varied.The decelerated injury and rolling injury occurred frequently and they were the main reasons for brain stem or diffuse axonal injury.The patients who have surgical indication should be operated upon as soon as possible.Hibernation and low temoerature therapy are conducive to the protection of the brain function at the early stage of postinjury or postoperation.A careful epluchage is essential to reduce infection of the open injury.

    Nonpenetrating chest trauma with injury to the heart and aorta has become increasingly common, particularly as a result of rapid deceleration in high-speed vehicular accidents, over the past 2-3 decades. The high mortality rate of cardiac injuries and possible late onset complications make blunt cardiac injuries an important challenging point for legal medicine. One hundred and ninety cases with blunt cardiac injuries in a period of 3 years were analyzed retrospectively in terms of patterns of cardiac injury, survival times, and demographic profiles of the cases in this study.

    Full Text Available Abstract Background Work-related burns are common among occupational injuries. Zhejiang Province is an industrial area with a high incidence of chemical burns. We aimed to survey epidemiological features of chemical burns in Zhejiang province to determine associated factors and acquire data for developing a strategy to prevent and treat chemical burns. Methods Questionnaires were developed, reviewed and validated by experts, and sent to 25 hospitals in Zhejiang province to prospectively collect data of 492 chemical burn patients admitted during one year from Sept. 1, 2008 to Aug. 31, 2009. Questions included victims' characteristics and general condition, injury location, causes of accident, causative chemicals, total body surface area burn, concomitant injuries, employee safety training, and awareness level of protective measures. Surveys were completed for each of burn patients by burn department personnel who interviewed the hospitalized patients. Results In this study, 417 victims (87.61% got chemical burn at work, of which 355 victims (74.58% worked in private or individual enterprises. Most frequent chemicals involved were hydrofluoric acid and sulfuric acid. Main causes of chemical injury accidents were inappropriate operation of equipment or handling of chemicals and absence of or failure to use effective individual protection. Conclusions Most chemical burns are preventable occupational injuries that can be attributed to inappropriate operation of equipment or handling of chemicals, lack of employee awareness about appropriate action and lack of effective protective equipment and training. Emphasis on safety education and protection for workers may help protect workers and prevent chemical burns.

  1. Abnormal strong burn-in degradation of highly efficient polymer solar cells caused by spinodal donor-acceptor demixing (United States)

    The performance of organic solar cells is determined by the delicate, meticulously optimized bulk-heterojunction microstructure, which consists of finely mixed and relatively separated donor/acceptor regions. Here we demonstrate an abnormal strong burn-in degradation in highly efficient polymer solar cells caused by spinodal demixing of the donor and acceptor phases, which dramatically reduces charge generation and can be attributed to the inherently low miscibility of both materials. Even though the microstructure can be kinetically tuned for achieving high-performance, the inherently low miscibility of donor and acceptor leads to spontaneous phase separation in the solid state, even at room temperature and in the dark. A theoretical calculation of the molecular parameters and construction of the spinodal phase diagrams highlight molecular incompatibilities between the donor and acceptor as a dominant mechanism for burn-in degradation, which is to date the major short-time loss reducing the performance and stability of organic solar cells.

    On January 2013, a disaster at Santa Maria (RS) due to a fire in a confined space caused 242 deaths, most of them by inhalation injury. On November 2013, four individuals required intensive care following smoke inhalation from a fire at the Memorial da América Latina in São Paulo (SP). The present article reports the clinical progression and management of disaster victims presenting with inhalation injury. Patients ERL and OC exhibited early respiratory failure, bronchial aspiration of carbonaceous material, and carbon monoxide poisoning. Ventilation support was performed with 100% oxygen, the aspirated material was removed by bronchoscopy, and cyanide poisoning was empirically treated with sodium nitrite and sodium thiosulfate. Patient RP initially exhibited cough and retrosternal burning and subsequently progressed to respiratory failure due to upper airway swelling and early-onset pulmonary infection, which were treated with protective ventilation and antimicrobial agents. This patient was extubated following improvement of edema on bronchoscopy. Patient MA, an asthmatic, exhibited carbon monoxide poisoning and bronchospasm and was treated with normobaric hyperoxia,bronchodilators, and corticosteroids. The length of stay in the intensive care unit varied from four to 10 days, and all four patients exhibited satisfactory functional recovery. To conclude, inhalation injury has a preponderant role in fires in confined spaces. Invasive ventilation should not be delayed in cases with significant airway swelling. Hyperoxia should be induced early asa therapeutic means against carbon monoxide poisoning, in addition to empiric pharmacological treatment in suspected cases of cyanide poisoning.

  5. A qualitative study of teachers' experiences of a school reintegration programme for young children following a burn injury. (United States)

    Wilson, Hannah M N; Gaskell, Sarah L; Murray, Craig D


    School reintegration programmes provide support to both children absent from school as a result of a serious health problem and their teachers, but little is known regarding their efficacy, or the impact of the situation on teachers. This qualitative study explored the experience of primary school teachers who were involved in a school reintegration programme, following a burn injury to a child in their class. Data was collected using semi-structured interviews with four primary school teachers. Transcripts were analysed using interpretative phenomenological analysis. The findings indicated that participants were positive regarding the programme, but detailed aspects which could be improved, for example better communication before the child's return. They discussed their fears and concerns, including a strong need to protect the child from further harm. Implications of this study include the need to provide adequate support to teachers in similar positions, and further develop school reintegration programmes to best facilitate the child's return to school.

    Full Text Available Background: Tear gas shells are used to disperse the mob during any type of street protests. Vascular injuries due to tear gas shells have not been reported. The present study was un-dertaken to analyse the pattern, presentation, management and outcome of vascular injury due to tear gas shells. Methods: Eighteen patients with vascular injury caused by tear gas shells from 1st Jan. 2008 to 31st Dec 2009 were studied. Patients with vascular injuries caused by causes other than tear gas shells were excluded from the study. Results: All patients were treated with reverse saphenous vein graft as segmental loss was less than 2.5 cm. Wound infection was the most common complication, followed by graft occlusion. Amputation rate was 16.66%. Associated nerve injury occurred in 44.44% of the patients. Conclusion: Tear gas shell injuries should not be taken lightly. They can cause injuries as serious as vascular injuries. Vascular injuries cased by tear gas shells require prompt revascularisation to improve limb salvage. De-spite proper revascularisation, patients have significant morbidity and need proper rehabilitation in the follow ups.

  7. Correlates of undefined cause of injury coded mortality data in Australia. (United States)

    McKenzie, Kirsten; Chen, Linping; Walker, Susan M


    The objective of this research was to identify the level of detail regarding the external causes of death in Australia and ascertain problematic areas where data quality improvement efforts may be focused. The 2003 national mortality dataset of 12,591 deaths with an external cause of injury as the underlying cause of death (UCOD) or multiple cause of death (MCOD) based on ICD-10 code assignment from death certificate information was obtained. Logistic regression models were used to examine the precision of coded external cause of injury data. It was found that overall, accidents were the most poorly defined of all intent code blocks with over 30% of accidents being undefined, representing 2,314 deaths in 2003. More undefined codes were identified in MCOD data than for UCOD data. Deaths certified by doctors were more likely to use undefined codes than deaths certified by a coroner or government medical office. To improve the quality of external cause of injuries leading to or associated with death, certifiers need to be made aware of the importance of documenting all information pertaining to the cause of the injury and the intent behind the incident, either through education or more explicit instructions on the death certificate and accompanying instructional materials. It is important that researchers are aware of the validity of the data when they make interpretations as to the underlying causes of fatal injuries and causes of injury associated with deaths.

  8. Estimating the distribution of external causes in hospital data from injury diagnosis. (United States)

    Bhalla, Kavi; Shahraz, Saeid; Naghavi, Mohsen; Lozano, Rafael; Murray, Christopher


    Hospital discharge datasets are a key source for estimating the incidence of non-fatal injuries. While hospital records usually document injury diagnosis (e.g. traumatic brain injury, femur fracture, etc.) accurately, they often contain poor quality information on external causes (e.g. road traffic crashes, falls, fires, etc.), if such data is recorded at all. However, estimating incidence by external causes is essential for designing effective prevention strategies. Thus, we developed a method for estimating the number of hospital admissions due to each external cause based on injury diagnosis. We start with a prior probability distribution of external causes for each case (based on victim age and sex) and use Bayesian inference to update the probabilities based on the victim's injury diagnoses. We validate the method on a trial dataset in which both external causes and injury diagnoses are known and demonstrate application to two problems: redistribution of cases classified to ill-defined external causes in one hospital data system; and, estimation of external causes in another hospital data system that only records nature of injuries. In comparison with age-sex proportional distribution (the method usually employed), we found the Bayesian method to be a significant improvement for generating estimates of incidence for many external causes (e.g. fires, drownings, poisonings). But the method, performed poorly in distinguishing between falls and road traffic injuries, both of which are characterized by similar injury codes in our datasets. While such stop gap methods can help derive additional information, hospitals need to incorporate accurate external cause coding in routine record keeping.

The face facilitates important social, including nonverbal, communication. Therefore, sustaining a severe burn, and in particular a facial burn, is a devastating and traumatizing injury. Burn survivors may encounter unique psychosocial problems and experience higher rates of psychosocial maladjustment, although there may be a number of potentially mediating factors. Objectives: The purpose of this phenomenological study was to examine the early recovery experience of patients with a facial burn. In particular, this study focused on how the injury impacted on the participants’ relationship with their own body and the challenges of early psychosocial adjustment within the first 4 months of sustaining the injury. Methods: In 2011, six adult participants encompassing two females and four males

  10. Burn wound: How it differs from other wounds?

    Directory of Open Access Journals (Sweden)

    V K Tiwari


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

    Pan-xi Yu; Wen-qi Diao; Zuo-liang Qi; Jing-long Cai


    Objective To explore the effects of dermabrasion combined with ReCell® on large superficial facial scars caused by burn, trauma and acnes. Methods Nineteen patients with large superficial facial scars were treated by the same surgeon with dermabrasion combined with ReCell®. According to the etiology, patients were classified into post-burning group (n=5), post-traumatic group (n=7) and post-acne group (n=7). Fifteen patients completed the follow-ups, 5 patients in each group. Healing time, complication rate, the preoperative and 18-month-post-operative assessments using Patient Satisfaction Score (PSS), Vancouver Scar Scale (VSS), and Patient and Observer Scar Assessment Scale (POSAS) of each group were analyzed to compare the effect of the combined therapy on outcomes. Results The healing time of post-burning group (19.6±4.0 days), post-traumatic group (15.8±2.6 days), and post-acne group (11.4±3.1 days) varied remarkably (F=7.701,P=0.007). The complication rates were 60%, 20%, and 0 respectively. The post-operative POSAS improved significantly in all groups (P<0.05), where the most significant improvement was shown in the post-acne group (P<0.05). The post-operative PSS and VSS improved only in the post-traumatic group and post-acne group (allP<0.05), where the more significant improvement was also shown in the post-acne group (P<0.05). Conclusions The combined treatment of dermabrasion and ReCell® has remarkable effect on acne scars, moderate effect on traumatic scars and is not suggested for burn scars. POSAS should be applied to assess the therapeutic effects of treatments for large irregular scars.

  12. Piriformis syndrome surgery causing severe sciatic nerve injury. (United States)

    Justice, Phillip E; Katirji, Bashar; Preston, David C; Grossman, Gerald E


    Piriformis syndrome is a controversial entrapment neuropathy in which the sciatic nerve is thought to be compressed by the piriformis muscle. Two patients developed severe left sciatic neuropathy after piriformis muscle release. One had a total sciatic nerve lesion, whereas the second had a predominantly high common peroneal nerve lesion. Follow-up studies showed reinnervation of the hamstrings only. We conclude that piriformis muscle surgery may be hazardous and result in devastating sciatic nerve injury.

  17. Characteristics of 985 pediatric burn patients in the south of Liaoning province of China

    Directory of Open Access Journals (Sweden)

    Hongjun Zhai


    Full Text Available Accidental injury due to burns is a serious and common, but preventable, occurrence in children. To analyze the characteristics of pediatric burns in the south of Liaoning province of China, a retrospective review was conducted of information, including general characteristics, demographics, etiology of burns, anatomical areas burned, and severity of injuries, obtained from medical records of pediatric burn patients admitted to the Burn Center of Anshan Hospital of the First Hospital of China Medical University from 2002 to 2011. Differences between age-groups and cause and severity of injuries were examined using Cochran-Mantel-Haenzsel ­(C-M-H statistic or chi-square (χ2 analyses where appropriate. A total of 985 pediatric burn cases were included, with only one death. The maximal burn area recorded was 80% and the maximal third-degree burn area was 45%. The majority of burns (637/985, 64.67% were moderate second-degree wounds, encompassing 5-14% of the total body surface area. The infant age-group (<3 years old had the largest representation (622/985, 63.15%, with more males than females affected. Most of the injuries occurred at home in children living in the local region. Scalding accounted for 89.85% (885/985 of all injuries, with a decreasing incidence with age, whereas injuries due to flames and from electrical sources markedly increased with age. Only a minority of guardians (244/985, 24.77% had burn prevention knowledge, and none of them knew how to provide first-aid treatment for burn injuries. These results indicate that the majority of pediatric burns occur in children less than 3 years of age from scalds received while at home. As a large proportion of these cases occurred in rural areas, programs emphasizing burn prevention and treatment knowledge should therefore be made more available to these families.

    Hong-Feng Zhao; Guo-Wei Zhang; Jie Zhou; Jian-Hua Lin; Zhong-Lin Cui; Xiang-Hong Li


    BACKGROUND: There is a controversy over the degree of liver and biliary injury caused by the period of secondary warm ischemia. A liver autotransplantation model was adopted because it excludes the effects of infection and immunological rejection on bile duct injury. This study was undertaken to assess biliary tract injury caused by relative warm ischemia (secondary warm ischemia time in the biliary tract) and reperfusion. METHODS: One hundred and two rats were randomly divided into 5 groups: groupⅠ (control); groupsⅡ toⅤ, relative warm ischemia times of 0 minute, 30 minutes, 1 hour and 2 hours. In addition to the levels of serum alkaline phosphatase, and total bilirubin, pathomorphology assessment and TUNEL assay were performed to evaluate biliary tract damage. RESULTS: Under the conditions that there were no signiifcant differences in warm ischemia time, cold perfusion time and anhepatic phase, group comparisons showed statistically signiifcant differences. The least injury occurred in groupⅡ (portal vein and hepatic artery reperfused simultaneously) but the most severe injury occurred in groupⅤ (biliary tract relative warm ischemia time 2 hours). CONCLUSIONS: Relative warm ischemia is one of the factors that result in bile duct injury, and the relationship between relative warm ischemia time the bile injury degree is time-dependent. Simultaneous arterial and portal reperfusion is the best choice to avoid the bile duct injury caused by relative warm ischemia.

  19. Characteristics and formation mechanism of a heavy air pollution episode caused by biomass burning in Chengdu, Southwest China. (United States)

    Chen, Yuan; Xie, Shao-Dong


    To track the chemical characteristics and formation mechanism of biomass burning pollution, the hourly variations of meteorological factors and pollutant concentrations during a heavy pollution on 18-21 May, 2012 in Chengdu are presented in this study. The episode was the heaviest and most long-lasting pollution event in the historical record of Chengdu caused by a combination of stagnant dispersion conditions and enhanced PM2.5 emission from intensive biomass burning, with peak values surpassing 500 μg m(-3). The event was characterized by three nighttime peaks, relating to the burning practice and decreased boundary layer height at night. The prevailing northeasterly wind during nighttime preferentially brought more pollutants to the urban regions from northern suburbs of Chengdu, where dense fire spots were observed. Due to the obstruction of hilly topography and weak wind speed, minor regional features were reflected from the PM10 variations in nearby cities, whereas the long-distance transport of the plume impacted extensive regions in northern and eastern China. Carbon monoxide (CO) concentrations increased by more than 200%, while exceptionally high PM2.5 levels of 190.1 and 268.4 μg m(-3) on 17 May and 18 May, were observed and showed high correlation with CO (r=0.75). The relative contribution of biomass burning smoke to organic carbon was estimated from OC/EC ratios (organic carbon/elemental carbon) and elevated to 81.3% during the episode, indicating a significant impact on urban aerosol levels. The occurrence of high PM2.5/PM10 ratios (>0.80) and K(+)/EC ratios (>1.0), along with the increased carbonaceous concentrations and their fraction in PM2.5 (>40%) and high OC/EC ratios (about 8), could be used as immediate indicators for biomass burning pollution in cities. In addition, the heavy pollution involved a mixture of anthropogenic sources, reflected from the high SOR and NOR values and increases in the EFs (enrichment factors) of Mo, Zn, Cd, and Pb.

  20. Suprascapular nerve injury: A cause to consider in shoulder pain and dysfunction. (United States)

    Yao, Kaihan; Yew, Wei Ping


    Suprascapular nerve injury is increasingly being recognized as an important cause of shoulder dysfunction. The non-specific clinical features of suprascapular nerve injury can make diagnosis difficult. However, it is essential for clinicians to consider it as part of the differential diagnoses in patients with vague pain or sensory disturbances over the posterosuperior part of their shoulder or have unexplained atrophy and weakness of their supraspinatus or infraspinatus muscle. Electrodiagnostic studies are useful in confirming and localising the nerve injury, while MRIs can be employed to determine the cause of nerve injury and assess the integrity of the rotator cuff muscles. Isolated suprascapular nerve injury can be managed with a trial of conservative management for at least 6 months. Subsequently, decompression of the nerve through open or arthroscopic techniques can be considered - both are associated with high rates of pain relief and functional improvement.

  1. A case of perforating injury of eyeball and traumatic cataract caused by acupuncture

    Directory of Open Access Journals (Sweden)

    Han Shuang


    Full Text Available Perforating globe injury is the leading cause of monocular blindness and vision loss. A 58-year-old male was injured by acupuncture needle during acupuncture treatment for his cerebral infarction. To the best of our knowledge, this is the first case report of perforating injury of the eyeball and traumatic cataract caused by acupuncture. The patient was hospitalized due to diagnosis of perforating ocular injury, traumatic cataract, and corneal and iris perforating injury. Moreover, he had to accept treatments of phacoemulsification, anterior vitrectomy along with intraocular lens implantation in the sulcus to improve his visual acuity. As acupuncture therapy has been widely performed for various diseases and achieved highly approval, the aim of this report is to remind acupuncturists operating accurately to avoid unnecessary injury during the treatment process, or the cure can also become the weapon.

    Billig Allan


    Full Text Available Abstract Introduction Toxic epidermal necrolysis is a rare exfoliative disorder with a high mortality rate. Case presentation We present a 70-year-old woman of Iranian descent who presented with toxic epidermal necrolysis that was initially diagnosed as a scald burn. Further anamnesis prompted by spread of the lesions during hospitalization revealed that the patient had been receiving ceftriaxone for several days. To the best of our knowledge, this is the first case of ceftriaxone-induced toxic epidermal necrolysis in the English literature. Conclusion Toxic epidermal necrolysis is an acute, life-threatening, exfoliative disorder with a high mortality rate. High clinical suspicion, prompt recognition, and initiation of supportive care is mandatory. Thorough investigation of the pathogenetic mechanisms is fundamental. Optimal treatment guidelines are still unavailable.

  5. The effect of virtual reality on pain and range of motion in adults with burn injuries. (United States)

    Carrougher, Gretchen J; Hoffman, Hunter G; Nakamura, Dana; Lezotte, Dennis; Soltani, Maryam; Leahy, Laura; Engrav, Loren H; Patterson, David R


    Few studies have empirically investigated the effects of immersive virtual reality (VR) on postburn physical therapy pain control and range of motion (ROM). We performed a prospective, randomized controlled study of the effects of adding VR to standard therapy in adults receiving active-assisted ROM physical therapy, by assessing pain scores and maximal joint ROM immediately before and after therapy on two consecutive days. Thirty-nine inpatients, aged 21 to 57 years (mean 35 years), with a mean TBSA burn of 18% (range, 3-60%) were studied using a within-subject, crossover design. All patients received their regular pretherapy pharmacologic analgesia regimen. During physical therapy sessions on two consecutive days (VR one day and no VR the other day; order randomized), each patient participated in active-assisted ROM exercises with an occupational or physical therapist. At the conclusion of each session, patients provided 0 to 100 Graphic Rating Scale measurements of pain after each 10-minute treatment condition. On the day with VR, patients wore a head-position-tracked, medical care environment-excluding VR helmet with stereophonic sound and interacted in a virtual environment conducive to burn care. ROM measurements for each joint exercised were recorded before and after each therapy session. Because of nonsignificant carryover and order effects, the data were analyzed using simple paired t-tests. VR reduced all Graphic Rating Scale pain scores (worst pain, time spent thinking about the pain, and pain unpleasantness by 27, 37, and 31% respectively), relative to the no VR condition. Average ROM improvement was slightly greater with the VR condition; however, this difference failed to reach clinical or statistical significance (P = .243). Ninety-seven percent of patients reported zero to mild nausea after the VR session. Immersive VR effectively reduced pain and did not impair ROM during postburn physical therapy. VR is easily used in the hospital setting and

  6. The air pollution caused by the burning of fireworks during the lantern festival in Beijing (United States)

    Wang, Ying; Zhuang, Guoshun; Xu, Chang; An, Zhisheng

    The effects of the burning of fireworks on air quality in Beijing was firstly assessed from the ambient concentrations of various air pollutants (SO 2, NO 2, PM 2.5, PM 10 and chemical components in the particles) during the lantern festival in 2006. Eighteen ions, 20 elements, and black carbon were measured in PM 2.5 and PM 10, and the levels of organic carbon could be well estimated from the concentrations of dicarboxylic acids. Primary components of Ba, K, Sr, Cl -, Pb, Mg and secondary components of C 5H 6O 42-, C 3H 2O 42-, C 2O 42-, C 4H 4O 42-, SO 42-, NO 3- were over five times higher in the lantern days than in the normal days. The firework particles were acidic and of inorganic matter mostly with less amounts of secondary components. Primary aerosols from the burning of fireworks were mainly in the fine mode, while secondary formation of acidic anions mainly took place on the coarse particles. Nitrate was mainly formed through homogeneous gas-phase reactions of NO 2, while sulfate was largely from heterogeneous catalytic transformations of SO 2. Fe could catalyze the formation of nitrate through the reaction of α-Fe 2O 3 with HNO 3, while in the formation of sulfate, Fe is not only the catalyst, but also the oxidant. A simple method using the concentration of potassium and a modified method using the ratio of Mg/Al have been developed to quantify the source contribution of fireworks. It was found that over 90% of the total mineral aerosol and 98% of Pb, 43% of total carbon, 28% of Zn, 8% of NO 3-, and 3% of SO 42- in PM 2.5 were from the emissions of fireworks on the lantern night.

  7. "Burn catatonia": a case report and literature review. (United States)

    Quinn, Davin Kenneth


    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.

    Arnon D. Cohen


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

    Okoro Philemon


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

    After the rats were iufficted with 8Gy total body gamma ray irradiation and 15% total body surface area (TBSA) full thickness burn injury, they were treated with blood transfusion (BT) and bone marrow transplantation (BMT). Then the survival of allografts grafted on the eschareetomized burn wounds in the 24, 48 and 72 h postinjury was observed. It was found that when the burn wounds were closed with allografts in the 24h postinjury, there were an early elevation of leucocytes, the appearance of the donor''s cells and a significantly higher survival rate of the rats on the 30 day postinjury. The allogaafts could survive longer and wounds showed no signs of infection and healed quicker. When the allografts were grafted in the 48 h or 72 h postinjury, only harmful effects to hasten the death of rats were observed.

  13. An unusual cause of acute kidney injury due to oxalate nephropathy in systemic scleroderma. (United States)

    Mascio, Heather M; Joya, Christie A; Plasse, Richard A; Baker, Thomas P; Flessner, Michael F; Nee, Robert


    Oxalate nephropathy is an uncommon cause of acute kidney injury. Far rarer is its association with scleroderma, with only one other published case report in the literature. We report a case of a 75-year-old African-American female with a history of systemic scleroderma manifested by chronic pseudo-obstruction and small intestinal bacterial overgrowth (SIBO) treated with rifaximin, who presented with acute kidney injury with normal blood pressure. A renal biopsy demonstrated extensive acute tubular injury with numerous intratubular birefringent crystals, consistent with oxalate nephropathy. We hypothesize that her recent treatment with rifaximin for SIBO and decreased intestinal transit time in pseudo-obstruction may have significantly increased intestinal oxalate absorption, leading to acute kidney injury. Oxalate nephropathy should be considered in the differential diagnosis of acute kidney injury in scleroderma with normotension, and subsequent evaluation should be focused on bowel function to include alterations in gut flora due to antibiotic administration.

    Wang, Xin-gang; Zhang, Yuan-hai; Han, Chun-mao


    Hydrofluoric acid (HF) is one of the most common inorganic acids used widely in industrial circle. HF not only causes cutaneous burn, but also induces systemic toxicity by its unique injury mechanism. Accurate and timely diagnosis and treatment are critical after HF burns. To date, the strategies for treating HF burns have been developed, mainly including topical treatments and systematic support. However, there is no standard treatment strategy with wide acceptance in the world. This paper presents a comprehensive overview of the advances in the research of strategies for the treatment of HF burns.

    Phrenic nerve injury after cardiac surgery increases postoperative pulmonary complications. The purpose of this study was to analyze the causes and effects of phrenic nerve injury after cardiac surgery. Prospectively collected data on 2084 consecutive patients who underwent cardiac surgery from Jan. 1995 to Feb. 2002 were analyzed. Twenty-eight preoperative and operation related variables were subjected to logistic analysis with the end point being phrenic nerve injury. Then phrenic nerve injury and 6 perioperative morbidities were included in the analysis as variables to determine their independent predictive value for perioperative pulmonary morbidity. An identical approach was used to identify the independent risk factors for perioperative mortality. There were 53 phrenic nerve injuries (2.5 %). There was no phrenic nerve injury in non-coronary surgery or coronary surgery using conduits other than the internal mammary artery. The independent risk factors for phrenic nerve injury were the use of internal mammary artery (Odds ratio (OR)=14.5) and the presence of chronic obstructive pulmonary disease (OR=2.9). Phrenic nerve injury was an independent risk factor (OR=8.1) for perioperative pulmonary morbidities but not for perioperative mortality. Use of semi-skeletonized internal mammary artery harvesting technique and drawing attention to possible vascular or mechanical causes of phrenic nerve injury may reduce its occurrence. Unilateral phrenic nerve injury, although rarely life-threatening, is an independent risk factor for postoperative respiratory complications. When harvesting internal mammary arteries, it should be kept in mind avoiding stretching, compromising, or inadvertently dissecting phrenic nerve is as important as avoiding damage of internal mammary artery itself.

    Directory of Open Access Journals (Sweden)

    Sh. Fahimi


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

  19. Dual therapeutic functions of F-5 fragment in burn wounds: preventing wound progression and promoting wound healing in pigs. (United States)

    Bhatia, Ayesha; O'Brien, Kathryn; Chen, Mei; Wong, Alex; Garner, Warren; Woodley, David T; Li, Wei


    Burn injuries are a leading cause of morbidity including prolonged hospitalization, disfigurement, and disability. Currently there is no Food and Drug Administration-approved burn therapeutics. A clinical distinction of burn injuries from other acute wounds is the event of the so-called secondary burn wound progression within the first week of the injury, in which a burn expands horizontally and vertically from its initial boundary to a larger area. Therefore, an effective therapeutics for burns should show dual abilities to prevent the burn wound progression and thereafter promote burn wound healing. Herein we report that topically applied F-5 fragment of heat shock protein-90α is a dual functional agent to promote burn wound healing in pigs. First, F-5 prevents burn wound progression by protecting the surrounding cells from undergoing heat-induced caspase 3 activation and apoptosis with increased Akt activation. Accordingly, F-5-treated burn and excision wounds show a marked decline in inflammation. Thereafter, F-5 accelerates burn wound healing by stimulating the keratinocyte migration-led reepithelialization, leading to wound closure. This study addresses a topical agent that is capable of preventing burn wound progression and accelerating burn wound healing.

    Isbister, G K; Warner, G


    A 67-year-old female suffered envenoming by a Sydney funnel-web spider (Atrax robustus), complicated by ST elevation and elevated troponin levels consistent with an acute myocardial injury. She was treated primarily with funnel-web spider antivenom, admission to intensive care and initial respiratory support for acute pulmonary oedema. The mechanism by which funnel-web spider envenomation caused myocardial injury is unclear but follow-up nuclear studies in the patient demonstrated that she had minimal atherosclerotic disease.

    Full Text Available Abstract Background Premature death from suicide is a leading cause of death worldwide. However, the pattern and risk factors for suicide and other external cause injuries are not well understood. This study investigates mortality from suicide and other injuries and associated risk factors in China. Methods A prospective cohort study of 169,871 Chinese adults aged 40 years and older was conducted. Mortality due to suicide or other external cause injuries was recorded. Results Mortality from all external causes was 58.7/100,000 (72.3 in men and 44.4 in women: 14.1/100,000 (14.2 in men and 14.2 in women for suicide and 44.6/100,000 (58.1 in men and 30.2 in women for other external cause injuries. Transport accidents (17.2/100,000 overall, 23.4 in men and 10.8 in women, accidental poisoning (7.5/100,000 overall, 10.2 in men and 4.8 in women, and accidental falls (5.7/100,000 overall, 6.5 in men and 5.0 in women were the three leading causes of death from other external cause injuries in China. In the multivariable analysis, male sex (relative risk [RR] 1.56, 95% confidence interval [CI] 1.03-2.38, age 70 years and older (2.27, 1.29-3.98, living in north China (1.68, 1.20-2.36 and rural residence (2.82, 1.76-4.51 were associated with increased mortality from suicide. Male sex (RR 2.50, 95% CI 1.95-3.20, age 60-69 years (1.93, 1.45-2.58 and 70 years and older (3.58, 2.58-4.97, rural residence (2.29, 1.77-2.96, and having no education (1.56, 1.00-2.43 were associated with increased mortality from other external cause injuries, while overweight (0.60, 0.43-0.83 was associated with decreased risk of mortality from other external cause injuries. Conclusions External cause mortality has become a major public health problem in China. Developing an integrated national program for the prevention of mortality due to external cause injuries in China is warranted.

    Wang, S.Y.; Zhang, H.X.; Fan, W.; Fang, S.J.; Kang, P.P.; Chen, X.G.; Yu, M.J. [Xinxiang Medical College, Xinxiang (China)


    The goal is to investigate the effects of endemic fluoride poisoning caused by coal burning on the physical development and intellectual ability of children. Random sampling from the relevant population, 176 fluorosis sufferers aged 7-12 (the subjects) were drawn from a heavily fluoride poisoned area of Zhijin County, with 50 children without dental fluorosis (the control) selected from a less severely poisoned area. The children were subjected to tests to determine levels of urinary fluoride, physical development, and intellectual ability, followed by analysis of the various measurements. Compared to the control group, the fluorosis group showed retarded physical development, and the levels of urinary fluoride and intellectual ability were both lower than the control (P < 0.05 for both). Conclusion: high fluoride burden has a definite effect on the intellectual and physical development of children.

  4. Epidemiology of pediatric burn in southern Taiwan. (United States)

    Lin, Tsai-Ming; Wang, Kai-Hung; Lai, Cheng-Sheng; Lin, Sin-Daw


    A 5-year retrospective review of 157 pediatric patients admitted to burn center of Kaohsiung Medical University Hospital (Kaohsiung, Taiwan) was undertaken to identify the incidence, mechanism, and agents of pediatric burn. The highest incidence of pediatric burn was in children aged 1-6 years (57.3%), followed by age group 6-14 years (31.8%). Scald burn (75.2%) made up the major cause of this injury and was dominant in each age group compared to non-scald burn. The kitchen/dining area (57.3%) and living room (29.9%) accounted for the most frequent places where pediatric burns occurred. Among the agents of scald burn, hot drink (49.2%) and soup (32.2%) were the two leading causes. There were more pediatric burns reported in colder seasons (38.2% and 33.1% in winter and fall respectively) and during dining time (19.7% in 11 a.m.-1 p.m. and 35.0% in 5 p.m.-8 p.m.). The results of this report may be closely related to special culinary habits (use of chafing-dish and making hot tea) in the south of Taiwan.

    Full Text Available BACKGROUND: Burn injuries are a major cause of morbidity and mortality in children. These are the third most common injury causing death in children, following motor vehicle accidents and drowning accidents. AIM: To study the Epidemiological parameters for assessment of morbidity & mortality rate in pediatric burns and to form effective preventive strategy. MATERIAL AND METHODS: The study was done at the Department of Surgery, PIMS, Jalandhar. Total 50 patients (n=50 up to age of 12 years, were included in the study retrospectively. Data regarding age, sex, demographic distribution, seasonal variation, Total body surface area (TBSA involved, type and place of burn injury, parent’s occupation, family size and mortality rate were noted and analysed. RESULT S: Total 50 patients (n =50 of which 32 were males and 18 females were included in the study. Mean age of burn injuries was 3.6 years. Scalds burns were the most common cause of burns followed by thermal burns. It involved mostly upper limbs (67%, anterio r trunk (56%, lower limbs (53%, face (4%, and posterior trunk including buttocks (16% . The time lapse from injury to presentation to hospital ranged from 1 hour to 3 weeks. Total body surface area burnt was ranged from 2 – 60%. Mean hospital duration was 12 . 4 days. Complications ranged from wound sepsis in 11 patients (22%, contractures of fingers in 3 patients ( 6 % and hypertrophic scarring in 8 patients (16% . After healing of wounds, patients were advised pressure garments and oil massage and night splint age regularly for six months. CONCLUSION: Children constitute a vulnerable group of burns. Most injuries occur in the home setting where effective control measures can be adopted. Advances have also made in resuscitation, intensive care, antimicrobi als, vascular access, nutritional support, and skin banking. Splintage, physiotherapy, massage and pressure garments also help in reducing the morbidity and overall long term burden over

  6. Honey oil burns: a growing problem. (United States)

    Jensen, Guy; Bertelotti, Robert; Greenhalgh, David; Palmieri, Tina; Maguina, Pirko


    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.

  8. Burns and epilepsy--review and case report. (United States)

    Gragnani, Alfredo; Müller, Bruno Rafael; Oliveira, Andrea Fernandes; Ferreira, Lydia Masako


    Decompensation of epilepsy in burned patients may be caused by several factors. Burn is a classic etiology of systemic inflammatory response syndrome, and evolves into two physiological phases. The first 48h after injury corresponds to the first phase involving severe hypovolemic shock. The second phase corresponds to the hypermetabolic response to burns. Altered pharmacokinetics of anticonvulsant drugs is observed. Albumin and other plasma proteins are reduced, leading to increased free fraction of phenytoin, resulting in greater clearance and a lower total drug concentration. Associated with metabolic changes of burned patient, this fact predisposes to seizures in epileptic burned patients. The authors present the case of an epileptic 36-year-old-woman who developed recurrent seizures after a thermal injury, despite using the same medications and doses of anticonvulsant drugs of last 12 years, with controlled epilepsy.

  9. Fabrication and hemocompatibility assessment of novel polyurethane-based bio-nanofibrous dressing loaded with honey and Carica papaya extract for the management of burn injuries (United States)

    Balaji, Arunpandian; Jaganathan, Saravana Kumar; Ismail, Ahmad Fauzi; Rajasekar, Rathanasamy


    Management of burn injury is an onerous clinical task since it requires continuous monitoring and extensive usage of specialized facilities. Despite rapid improvizations and investments in burn management, >30% of victims hospitalized each year face severe morbidity and mortality. Excessive loss of body fluids, accumulation of exudate, and the development of septic shock are reported to be the main reasons for morbidity in burn victims. To assist burn wound management, a novel polyurethane (PU)-based bio-nanofibrous dressing loaded with honey (HN) and Carica papaya (PA) fruit extract was fabricated using a one-step electrospinning technique. The developed dressing material had a mean fiber diameter of 190±19.93 nm with pore sizes of 4–50 µm to support effective infiltration of nutrients and gas exchange. The successful blending of HN- and PA-based active biomolecules in PU was inferred through changes in surface chemistry. The blend subsequently increased the wettability (14%) and surface energy (24%) of the novel dressing. Ultimately, the presence of hydrophilic biomolecules and high porosity enhanced the water absorption ability of the PU-HN-PA nanofiber samples to 761.67% from 285.13% in PU. Furthermore, the ability of the bio-nanofibrous dressing to support specific protein adsorption (45%), delay thrombus formation, and reduce hemolysis demonstrated its nontoxic and compatible nature with the host tissues. In summary, the excellent physicochemical and hemocompatible properties of the developed PU-HN-PA dressing exhibit its potential in reducing the clinical complications associated with the treatment of burn injuries.

    Full Text Available Indian crested porcupine (Hystrix indica is a member of the family of Old World porcupines (Hystricidae. Its body is covered with multiple layers of quills, which serve for warning and attack if animal is threatened. However, the literature data on injuries caused by Indian crested porcupine are absent. We describe pathomorphological lesions in an Indian crested porcupine from the Ljubljana Zoo, which died after a fight with a younger male that caused a perforative quill injury of the thoracic wall, followed by septicaemia. Macroscopic, microscopic and bacteriological findings were detailed

    F Panahi


    Full Text Available Introduction: In this retrospective study, we decided to determine the death causes and severity of injuries in traffic accidents according to reports of the forensic medical center of Yazd. Methods: A total of 251 fatalities due to traffic accidents that had undergone autopsy examinations at the Yazd forensic medicine center from2006 till 2008 were included in the study by census method. Data regarding gender, road user type, type of vehicle (car, motorcycle, autobus or minibus, consciousness level, and intensive care unit (ICU admission was gathered. For evaluation of injury severity, we used Injury Severity Score (ISS. Results: The population under study consisted of 202 men (80.5% and 49 women (19.5% with an average age of 34.1 years (range: 1-89 years. Motorcycle-pedestrian accidents were the most common type of injury (100, 39.8%. Head (220, 87.6% and face (169, 67.3% were the two most common sites of injuries. Mean (±SD of ISS was 23.2 (±10.4. According to autopsy records, the main cause of death was head trauma (146, 58.1%. Conclusion: Public awareness in terms of primary prevention of road accidents should be considered important. Also, regarding the high prevalence of brain injuries and complications associated with skull fractures, accessibility to neurosurgeons and availability of imaging devices have an important role in decreasing the mortality rate of traffic accidents.

    XIANG Jun; SUN Zhen; HUAN Jing-ning


    In this case report, we describe our experience of managing a patient with chemical burns caused by hot chromic acid that covered over 60% of the patient's body. The patient developed anuria 48 hours after injury. Early excision of burn eschars and hemodialysis were carried out. The patient survived after a series of comprehensive treatments, including allografting and autografting. In patients burned by hot chromic acid, excision of affected skin down to the muscle fascia should be carried out as soon as possible after injury. Dialysis to remove circulating chromium in the first 24 hours after injury is also recommended.

  13. Rethinking airbag safety: Airbag injury causing bilateral blindness

    Directory of Open Access Journals (Sweden)

    Olufunmilola Abimbola Ogun


    Full Text Available A healthy 40-year-old man, restrained in the front passenger seat, suffered visually disabling blunt ocular trauma following spontaneous release of the passenger side air-bag module, during vehicular deceleration, without an automobile crash. Though the driver-side airbag was also released, the driver was unharmed. The passenger suffered bilateral hyphema, bilateral vitreous hemorrhage and suspected posterior scleral rupture in the left eye and also had an eyebrow laceration, from impact with the dashboard panel covering the air-bag module, which was detached by the force of airbag deployment. This is the first reported case from West Africa and the first case in which part of the airbag module detached to cause additional trauma. This report adds to the growing burden of evidence world-wide, for a review of the safety aspects of the automobile airbag. This case clearly illustrates that although airbags reduce mortality, they carry a high risk of ocular morbidity, even with seat belt restraint.

    Hagiuda, J; Ishikawa, H; Hanawa, Y; Marumo, K


    Some cases of testicular trauma cause infertility especially when the injured testes are not removed. However, only a few long-term follow-up studies investigating endocrinological and semen parameters in patients who had testicular trauma have been conducted. Herein, we report an interesting case of a patient who spontaneously recovered from azoospermia due to a traffic injury and present in detail the results of the hormonal examination and semen analysis. The patient was a 22-year-old man with a history of left testicular injury and bilateral orchidopexy. Four months after the injury, the semen parameters improved but azoospermia occurred 1 year later. However, spermatogenesis spontaneously recovered without any treatment or without undergoing orchiectomy 6 months after the testicular injury.

    Objective To explore the changes of intestinal trefoil factor(ITF) as well as ITF mRNA expression in rat small intestine after severe burn injury .  Methods The distribution and the content of ITF in intestine were quantitatively determined with in situ hybridization (ISH), immunohistochemistry and high performance liquid chromatography (HPLC).  Results ITF and ITF mRNA were distributed in whole small intestine and most of them localized in goblet cell of intestinal villus. After burn injury, the structure of intestinal mucosa was severely damaged and ITF mRNA expression was lessened. Moreover, the ability of goblet cell synthesis and ITF secretion, especially ITF dimmer were significantly decreased, i.e., from (369.33±65.56) ng/g before burn injury to (15.83±4.40) ng/g 7 days after burn injury, only accounting for 4% of that before injury. Conclusions The post burn damage to intestinal structure is the main cause for the declination in ability of goblet cell synthesis and ITF secretion; and ITF drop especially ITF dimmer can enhance intestinal mucosa injury and delay intestinal mucosa repair.%目的 探讨严重烧伤对大鼠肠三叶因子(ITF)及其mRNA表达的影响及意义。 方法 48只健康成年Wistar大鼠,制成30%TBSAⅢ度烧伤模型并随机分成正常对照组及伤后1,2,3,5,7 d共6组,每组8只。采用原位杂交、免疫组化等手段观察伤后ITF 及ITF mRNA表达的变化,并使用高效液相色谱仪对肠黏膜ITF含量进行定量检测。 结果 正常对照组大鼠小肠中ITF及ITF mRNA均有一定表达,它们主要分布于肠绒毛杯状细胞中。烧伤后肠黏膜组织结构受损,ITF mRNA表达明显减少,肠杯状细胞合成和分泌ITF的能力大幅下降(P<0.01),特别是ITF二聚体的含量远远低于伤前[(369.33±65.56) ng/g],伤后7 d[(15.83±4.40) ng/g]仅为伤前的4%。 结论 严重烧伤后肠黏膜组织结构受损是ITF合成

  17. Antecedent thermal injury worsens split-thickness skin graft quality: A clinically relevant porcine model of full-thickness burn, excision and grafting. (United States)

    Carlsson, Anders H; Rose, Lloyd F; Fletcher, John L; Wu, Jesse C; Leung, Kai P; Chan, Rodney K


    Current standard of care for full-thickness burn is excision followed by autologous split-thickness skin graft placement. Skin grafts are also frequently used to cover surgical wounds not amenable to linear closure. While all grafts have potential to contract, clinical observation suggests that antecedent thermal injury worsens contraction and impairs functional and aesthetic outcomes. This study evaluates the impact of antecedent full-thickness burn on split-thickness skin graft scar outcomes and the potential mediating factors. Full-thickness contact burns (100°C, 30s) were created on the backs of anesthetized female Yorkshire Pigs. After seven days, burn eschar was tangentially excised and covered with 12/1000th inch (300μm) split-thickness skin graft. For comparison, unburned wounds were created by sharp excision to fat before graft application. From 7 to 120days post-grafting, planimetric measurements, digital imaging and biopsies for histology, immunohistochemistry and gene expression were obtained. At 120days post-grafting, the Observer Scar Assessment Scale, colorimetry, contour analysis and optical graft height assessments were performed. Twenty-nine porcine wounds were analyzed. All measured metrics of clinical skin quality were significantly worse (pskin graft quality, likely by multiple mechanisms including burn-related inflammation, microscopically inadequate excision, and dysregulation of tissue remodeling. A valid, reliable, clinically relevant model of full-thickness burn, excision and skin replacement therapy has been demonstrated. Future research to enhance quality of skin replacement therapies should be directed toward modulation of inflammation and assessments for complete excision.

    Full Text Available Physicians who first meet with burned patients are often emergency service employees. When the patient was admitted to emergency service, especially in patients with major burn injury, is a matter should be dealt with strongly. Before sending the patients to a burn center, some interventions could became life saving which should be done as a first line treatment. Herein, review of the literature related to emergency burn treatment was performed and presented to all physicians as a summary guide. In addition, some questions such as how should be physician, who first meet with the burned patient, evaluated the patient, what should be physician paid attention, which principles should be employed for fluid replacement, how should be approached to burn wound are tried to be addressed.

  19. Sustainable antimicrobial effect of silver sulfadiazine-loaded nanosheets on infection in a mouse model of partial-thickness burn injury. (United States)

    Ito, Keisuke; Saito, Akihiro; Fujie, Toshinori; Nishiwaki, Keisuke; Miyazaki, Hiromi; Kinoshita, Manabu; Saitoh, Daizoh; Ohtsubo, Shinya; Takeoka, Shinji


    Partial-thickness burn injury has the potential for reepithelialization and heals within 3weeks. If the wound is infected by bacteria before reepithelization, however, the depth of disruption increases and the lesion easily progresses to the full-thickness dermal layers. In the treatment of partial-thickness burn injury, it is important to prevent the wound area from bacterial infection with an antimicrobial dressing. Here, we have tested the antimicrobial properties of polymeric ultra-thin films composed of poly(lactic acid) (termed "PLA nanosheets"), which have high flexibility, adhesive strength and transparency, and silver sulfadiazine (AgSD), which exhibits antimicrobial efficacy. The AgSD-loaded nanosheet released Ag(+) for more than 3days, and exerted antimicrobial efficacy against methicillin-resistant Staphylococcus aureus (MRSA) in an in vitro Kirby-Bauer test. By contrast, a cell viability assay indicated that the dose of AgSD used in the PLA nanosheets did not show significant cytotoxicity toward fibroblasts. In vivo evaluation using a mouse model of infection in a partial-thickness burn wound demonstrated that the nanosheet significantly reduced the number of MRSA bacteria on the lesion (more than 10(5)-fold) and suppressed the inflammatory reaction, thereby preventing a protracted wound healing process.

  20. Effects of fluid resuscitation methods on the pro- and anti-inflammatory cytokines and expression of adhesion molecules after burn injury. (United States)

    Foldi, Viktor; Lantos, Janos; Bogar, Lajos; Roth, Elizabeth; Weber, Gyorgy; Csontos, Csaba


    Fluid resuscitation management can influence inflammatory response after burn injury. The aim of this study was to analyze the effects of two fluid resuscitation methods on the cytokine production and on the expression of the leukocyte surface markers. Thirty patients were included in this prospective randomized study with burn injury affecting more than 20% of the body surface area. Fluid resuscitation was guided by hourly urine output (HUO, n = 15) or by intrathoracic blood volume index (ITBVI, n = 15). Blood samples were taken on admission and on the next five consecutive mornings. Concentrations of interleukin (IL)-1beta, IL-6, IL-8, IL-10, IL-12p70, and tumor necrosis factor-alpha were measured in phorbol myristate acetate-stimulated and -nonstimulated samples. Leukocyte surface marker expressions (CD11a, CD11b, CD14, CD18, CD49d, and CD97) were also determined. In the ITBVI group, IL-6 levels on days 2 to 3 and IL-6/IL-10 ratios on days 2 to 3, and the IL-8/IL-10 ratios on days 3 to 5 were significantly higher than those in HUO group (P burned patients suppresses the shift toward anti-inflammatory imbalance and the expression of leukocyte surface markers more than HUO-guided resuscitation.

  1. Systematic care management: a comprehensive approach to catastrophic injury management applied to a catastrophic burn injury population--clinical, utilization, economic, and outcome data in support of the model. (United States)

    Kucan, John; Bryant, Ernest; Dimick, Alan; Sundance, Paula; Cope, Nathan; Richards, Reginald; Anderson, Chris


    The new standard for successful burn care encompasses both patient survival and the burn patient's long-term quality of life. To provide optimal long-term recovery from catastrophic injuries, including catastrophic burns, an outcome-based model using a new technology called systematic care management (SCM) has been developed. SCM provides a highly organized system of management throughout the spectrum of care that provides access to outcome data, consistent oversight, broader access to expert providers, appropriate allocation of resources, and greater understanding of total costs. Data from a population of 209 workers' compensation catastrophic burn cases with a mean TBSA of 27.9% who were managed under the SCM model of care were analyzed. The data include treatment type, cost, return to work, and outcomes achieved. Mean duration of management to achieve all guaranteed outcomes was 20 months. Of the 209 injured workers, 152 (72.7%) achieved sufficient recovery to be released to return to work, of which 97 (46.8%) were both released and competitively employed. Assessment of 10 domains of functional independence indicated that 47.2% of injured workers required total assistance at initiation of SCM. However, at termination of SCM, 84% of those injured workers were fully independent in the 10 functional activities. When compared with other burn research outcome data, the results support the value of the SCM model of care.

  2. Critical issues in burn care. (United States)

    Holmes, James H


    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.

  3. Thalidomide decreases the plasma levels of IL-1 and TNF following burn injury: is it a new drug for modulation of systemic inflammatory response. (United States)

    Eski, Muhitdin; Sahin, Ismail; Sengezer, Mustafa; Serdar, Muhittin; Ifran, Ahmet


    TNF and IL-1, which are produced from phagocytic cells, can produce a significant systemic inflammatory response independently by inducing systemic leukocyte and endothelial cell activation. These cytokines play a pivotal role in development of systemic inflammatory response after severe burn. Thalidomide has been shown to decrease the secretion of TNF from phagocytic cells, therefore suppression of TNF and IL-1 production from activated phagocytic cells might be a successful treatment modality for prevention of systemic inflammatory response following severe burn. To address this issue, we aimed to show whether thalidomide treatment decreased or suppressed plasma levels of TNF and IL-1 following burn in rats. Following the injury, 36 rats were randomly separated into two experimental groups at the third and seventh days. Rats in the experimental group had oral thalidomide (10mg/kg day) treatment for three and seven consecutive days whereas animals in control groups had no treatment. Thalidomide treatment decreased TNF and IL-1 significantly in both experimental groups at both the points (PTNF and IL-1, we speculate that thalidomide may have modulatory effect on the systemic inflammatory response after burn by decreasing plasma levels of TNF and IL-1.

  7. Spinal Cord Injury Caused by Stab Wounds: Incidence, Natural History, and Relevance for Future Research. (United States)

    McCaughey, Euan J; Purcell, Mariel; Barnett, Susan C; Allan, David B


    Spinal cord injury caused by stab wounds (SCISW) results from a partial or complete transection of the cord, and presents opportunities for interventional research. It is recognized that there is low incidence, but little is known about the natural history or the patient's suitability for long-term clinical outcome studies. This study aims to provide population-based evidence of the demographics of SCISW, and highlight the issues regarding the potential for future research. The database of the Queen Elizabeth National Spinal Injuries Unit (QENSIU), the sole center for treating SCI in Scotland, was reviewed between 1994 and 2013 to ascertain the incidence, demographics, functional recovery, and mortality rates for new SCISW. During this 20 year period, 35 patients with SCISW were admitted (97.1% male, mean age 30.0 years); 31.4% had a cervical injury, 60.0% had a thoracic injury, and 8.6% had a lumbar injury. All had a neurological examination, with 42.9% diagnosed as motor complete on admission and 77.1% discharged as motor incomplete. A total of 70.4% of patients with an American Spinal Injury Association Impairment Scale (AIS) level of A to C on admission had an improved AIS level on discharge. Nine (25.7%) patients have died since discharge, with mean life expectancy for these patients being 9.1 years after injury (20-65 years of age). Patients had higher levels of comorbidities, substance abuse, secondary events, and poor compliance compared with the general SCI population, which may have contributed to the high mortality rate observed post-discharge. The low incidence, heterogeneous nature, spontaneous recovery rate, and problematic follow-up makes those with penetrating stab injuries of the spinal cord a challenging patient group for SCI research.

    In the wound healing process after a deep burn injury,improper treatment in the early stage and lack of functional rehabilitation measures in the late stage usually lead tohyperplastic scar,joint contracture,synarthrophysis,and other deformities.All of them may result in cosmetic and functional impairments,loss of work ability,poor life quality,and even psychopathy of the patients.Thus,the improvement in rehabilitation methods and the maximal recovery of appearance and functions have drawn intense attention.This article mainly discusses the prevention,systematic treatment principles and methods for the hyperplastic scar and scar contracture,as well as the problems need to be solved in burn rehabilitation,based on the introduction of the new advancement in the rehabilitation techniques.

  9. Risk factors for frequent work-related burn and cut injuries and low back pain among commercial kitchen workers in Japan. (United States)

    Tomita, Shigeru; Muto, Takashi; Matsuzuki, Hiroe; Haruyama, Yasuo; Ito, Akiyoshi; Muto, Shigeki; Haratani, Takashi; Seo, Akihiko; Ayabe, Makoto; Katamoto, Shizuo


    This study investigated risk factors for frequent work-related burn and cut injuries and low back pain (LBP) among kitchen workers including personal, work-related and environmental factors. Subjects were 991 kitchen workers in 103 schools, 17 hospitals and nursing homes, and 6 restaurants in central Japan. A cross-sectional survey was carried out using a structured self-administered questionnaire. Logistic regression models were used to examine associations between frequent injuries/LBP and risk factors. The effective response rate was 75.1% (n=744), the mean age was 40.7 (SD 11.7) and 77.2% were female. Burn injury was associated with a smaller kitchen (OR 1.94; 95%CI, 1.13-3.33), and gas kitchens rather than electric kitchens (OR 2.30; 95%CI, 1.17-4.52). LBP was associated with female gender (OR 2.46; 95%CI, 1.37-4.43), high body height (>160 cm) (OR 2.03; 95%CI, 1.22-3.36), and large number of meals produced per person (≥ 150 meals) (OR 1.83; 95%CI, 1.12-3.00). The results of this study suggest that securing adequate work space and introducing electric kitchen systems may reduce the risk to kitchen workers, as well as the importance of adequate height of cooking equipment and selecting an appropriate volume of meals to produce per person to prevent LBP in kitchen workers.

    Yu Chen; Liangbi Xiang; Jun Liu; Dapeng Zhou; Hailong Yu; Qi Wang; Wenfeng Han; Mingming Guo


    Intrathecal injection of dynorphin into rats via subarachnoid catheter induces damage to spinal cord tissue and motor function. Injection of the kappa opioid receptor antagonist nor-binaltorphine, or the excitatory amino acid N-methyl-D-aspartate receptor antagonist MK-801 into rats alleviated the pathological changes of dynorphin-caused spinal cord tissue injury and reduced the acid phosphatase activity in the spinal cord. The experimental findings indicate that there are opioid and non-opioid pathways for dynorphin-induced spinal cord injury, and that the non-opioid receptor pathway may be mediated by the excitatory amino acid N-methyl-D-aspartate receptor.

  14. Is the Target of 1 Day of Stay per 1% Total Body Surface Area Burned Achieved in Chemical Burns? (United States)

    Tan, Teresa; Wong, David S Y


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

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

    Full Text Available Introduction: A high grade burn is one of the most devastating injuries with several medical, social, economic, and psychological effects. These injuries are the most common cause of accidental deaths after traffic injuries in both the developed and developing countries. Therefore this research was aimed to determine demographic characteristics of patients with burn injury admitted to the emergency department and identify predictive factors of hospitalization. Methods: This is a cross sectional descriptive study, which is done in 20 March up to 20 September 2011 in emergency department of Sina Hospital, Tabriz, Iran. Patients’ information including demographic characteristic, cause of burn, place of accident, anatomical areas burned, grading and percent of burning and disposition were gathered and analyzed using SPSS version 18.0 statistical software. Stepwise multivariate regression analysis was used for recognition of independent predictive factors of hospitalization in burned patients. Results: One hundred and sixty patients were enrolled (54.4% female. The average age of those was 20.47±13.5 years. The prevalence of burn was significantly higher in ages under 20 years (p<0.001. Lower limb (37.5%, head and neck (21.25% and upper limb (17.5% were three frequent site of burn. The most common cause of burns was boiling water scalding (34.4%.

  20. Chaparral ingestion. The broadening spectrum of liver injury caused by herbal medications. (United States)

    Gordon, D W; Rosenthal, G; Hart, J; Sirota, R; Baker, A L


    Unconventional medical practices, including the use of herbal remedies, are prevalent in the United States. Chaparral is an herbal preparation made from a desert shrub and used for its antioxidant properties. We report the case of a 60-year-old woman who took chaparral for 10 months and developed severe hepatitis for which no other cause could be found. Despite aggressive supportive therapy, the patient deteriorated and required orthotopic liver transplantation. She is now well, more than 1 year after her transplant. This case suggests that chaparral can cause serious liver injury and fulminant hepatic failure. Herbal medications should be considered as potential causes of liver toxicity.

  2. Mesenteric lymph reperfusion exacerbates spleen injury caused by superior mesenteric artery occlusion shock

    Li, L.L.; Zhang, C.H.; Liu, J.C.; Yang, L.N.; Niu, C.Y.; Zhao, Z.G. [Institute of Microcirculation, Hebei North University, Zhangjiakou, Hebei, China, Institute of Microcirculation, Hebei North University, Zhangjiakou, Hebei (China)


    The intestinal lymph pathway plays an important role in the pathogenesis of organ injury following superior mesenteric artery occlusion (SMAO) shock. We hypothesized that mesenteric lymph reperfusion (MLR) is a major cause of spleen injury after SMAO shock. To test this hypothesis, SMAO shock was induced in Wistar rats by clamping the superior mesenteric artery (SMA) for 1 h, followed by reperfusion for 2 h. Similarly, MLR was performed by clamping the mesenteric lymph duct (MLD) for 1 h, followed by reperfusion for 2 h. In the MLR+SMAO group rats, both the SMA and MLD were clamped and then released for reperfusion for 2 h. SMAO shock alone elicited: 1) splenic structure injury, 2) increased levels of malondialdehyde, nitric oxide (NO), intercellular adhesion molecule-1, endotoxin, lipopolysaccharide receptor (CD14), lipopolysaccharide-binding protein, and tumor necrosis factor-α, 3) enhanced activities of NO synthase and myeloperoxidase, and 4) decreased activities of superoxide dismutase and ATPase. MLR following SMAO shock further aggravated these deleterious effects. We conclude that MLR exacerbates spleen injury caused by SMAO shock, which itself is associated with oxidative stress, excessive release of NO, recruitment of polymorphonuclear neutrophils, endotoxin translocation, and enhanced inflammatory responses.

    Full Text Available Abstract Background Ankle pain and swelling following sports injuries are common presenting complaints to the accident and emergency department. Frequently these are diagnosed as musculoskeletal injuries, even when no definitive cause is found. Vascular injuries following trauma are uncommon and are an extremely rare cause of ankle swelling and pain. These injuries may however be limb threatening and are important to diagnose early, in order that appropriate treatment can be delivered. We highlight the steps to diagnosis of these injuries, and methods of managing these injuries. It is important for clinicians to be aware of the potential for this injury in patients with seemingly innocuous trauma from sports injuries, who have significant ankle pain and swelling. Case presentation A young, professional sportsman presented with a swollen, painful ankle after an innocuous hyper-plantar flexion injury whilst playing football, which was initially diagnosed as a ligamentous injury after no bony injury was revealed on X-Ray. He returned 2 days later with a large ulcer at the lateral malleolus and further investigation by duplex ultrasound and transfemoral arteriogram revealed a Pseudo-Aneurysm of the Anterior Tibial Artery. This was initially managed with percutaneous injection of thrombin, and later open surgery to ligate the feeding vessel. The patient recovered fully and was able to return to recreational sport. Conclusion Vascular injuries remain a rare cause of ankle pain and swelling following sports injuries, however it is important to consider these injuries when no definite musculo-skeletal cause is found. Ultrasound duplex and Transfemoral arteriogram are appropriate, sensitive modalities for investigation, and may allow novel treatment to be directed percutaneously. Early diagnosis and intervention are essential for the successful outcome in these patients.

    Full Text Available Extracorporeal shock wave therapy (ESWT enhances tissue vascularization and neoangiogenesis. Recent animal studies showed improved soft tissue regeneration using ESWT. In most cases, deep partial-thickness burns require skin grafting; the outcome is often unsatisfactory in function and aesthetic appearance. The aim of this study was to demonstrate the effect of ESWT on skin regeneration after deep partial-thickness burns. Under general anesthesia, two standardized deep partial-thickness burns were induced on the back of 30 male Wistar rats. Immediately after the burn, ESWT was given to rats of group 1 (N=15, but not to group 2 (N=15. On days 5, 10, and 15, five rats of each group were analyzed. Reepithelialization rate was defined, perfusion units were measured, and histological analysis was performed. Digital photography was used for visual documentation. A wound score system was used. ESWT enhanced the percentage of wound closure in group 1 as compared to group 2 (P<0.05. The reepithelialization rate was improved significantly on day 15 (P<0.05. The wound score showed a significant increase in the ESWT group. ESWT improves skin regeneration of deep partial-thickness burns in rats. It may be a suitable and cost effective treatment alternative in this type of burn wounds in the future.

  5. Management of a Low-Energy Penetrating Brain Injury Caused by a Nail

    V. R. Ferraz


    Full Text Available Low-energy penetrating nail injury to the brain is an extremely rare neurosurgical emergency. The most common cause of nail gun injury is work related accidents; other causes result from accidental firing of a nail gun, suicide attempts by firing nail guns into the brain, and bomb blasts containing pieces of nails. Neurosurgical treatment performed by craniotomy still seems to be the safest one; there are reports of complications such as subdural hematoma and intraparenchymal hemorrhages following the blind removal of foreign bodies leading to suggestions that all penetrating foreign bodies should be removed under direct vision. We report a rarely described neurosurgical approach for removal of a penetrating nail from the brain and skull without evidence of associated hematoma and other brain lesions.

  7. Fatal injuries caused by guns using shotshell: case reports and ballistic studies. (United States)

    Rougé, D; Telmon, N; Alengrin, D; Marril, G; Bras, P M; Arbus, L


    The authors present six cases of homicide and suicide in which the weapon involved was a handgun using shotshell. The injuries caused are described and the ballistic characteristics of the weapons are studied. Such weapons, which are relatively easy to obtain, are not as innocuous as they may appear, since they may be modified either by changing the barrel or by removal of the device inside the barrel which is intended to prevent the firing of solid slugs.

Despite rapid improvizations and investments in burn management, >30% of victims hospitalized each year face severe morbidity and mortality. Excessive loss of body fluids, accumulation of exudate, and the development of septic shock are reported to be the main reasons for morbidity in burn victims. To assist burn wound management, a novel polyurethane (PU-based bio-nanofibrous dressing loaded with honey (HN and Carica papaya (PA fruit extract was fabricated using a one-step electrospinning technique. The developed dressing material had a mean fiber diameter of 190±19.93 nm with pore sizes of 4–50 µm to support effective infiltration of nutrients and gas exchange. The successful blending of HN- and PA-based active biomolecules in PU was inferred through changes in surface chemistry. The blend subsequently increased the wettability (14% and surface energy (24% of the novel dressing. Ultimately, the presence of hydrophilic biomolecules and high porosity enhanced the water absorption ability of the PU

  9. The global burden of child burn injuries in light of country level economic development and income inequality. (United States)

    Sengoelge, Mathilde; El-Khatib, Ziad; Laflamme, Lucie


    Child burn mortality differs widely between regions and is closely related to material deprivation, but reports on their global distribution are few. Investigating their country level distribution in light of economic level and income inequality will help assess the potential for macro-level improvements. We extracted data for child burn mortality from the Global Burden of Disease study 2013 and combined data into 1-14 years to calculate rates at country, region and income levels. We also compiled potential lives saved. Then we examined the relationship between country level gross domestic product per capita from the World Bank and income inequality (Gini Index) from the Standardized World Income Inequality Database and child burn mortality using Spearman coefficient correlations. Worldwide, the burden of child burn deaths is 2.5 per 100,000 across 103 countries with the largest burden in Sub-Saharan Africa (4.5 per 100,000). Thirty-four thousand lives could be saved yearly if all countries in the world had the same rates as the best performing group of high-income countries; the majority in low-income countries. There was a negative graded association between economic level and child burns for all countries aggregated and at regional level, but no consistent pattern existed for income inequality at regional level. The burden of child burn mortality varies by region and income level with prevention efforts needed most urgently in middle-income countries and Sub-Saharan Africa. Investment in safe living conditions and access to medical care are paramount to achieving further reductions in the global burden of preventable child burn deaths.

Each selected article is mentioned briefly with editorial comment.

  11. Loss of the intestinal mucus layer in the normal rat causes gut injury but not toxic mesenteric lymph nor lung injury. (United States)

    Sharpe, Susan M; Qin, Xiaofa; Lu, Qi; Feketeova, Eleonora; Palange, David C; Dong, Wei; Sheth, Sharvil U; Lee, Marlon A; Reino, Diego; Xu, Da-Zhong; Deitch, Edwin A


    There is substantial evidence that gut barrier failure is associated with distant organ injury and systemic inflammation. After major trauma or stress, the factors and mechanisms involved in gut injury are unknown. Our primary hypothesis is that loss of the intestinal mucus layer will result in injury of the normal gut that is exacerbated by the presence of luminal pancreatic proteases. Our secondary hypothesis is that the injury produced in the gut will result in the production of biologically active mesenteric lymph and consequently distant organ (i.e., lung) injury. To test this hypothesis, five groups of rats were studied: 1) uninstrumented naive rats; 2) control rats in which a ligated segment of distal ileum was filled with saline; 3) rats with pancreatic proteases placed in their distal ileal segments; 4) rats with the mucolytic N-acetylcysteine (NAC) placed in their distal ileal segments; and 5) rats exposed to NAC and pancreatic proteases in their ileal segments. The potential systemic consequences of gut injury induced by NAC and proteases were assessed by measuring the biological activity of mesenteric lymph as well as gut-induced lung injury. Exposure of the normal intestine to NAC, but not saline or proteases, led to increased gut permeability, loss of mucus hydrophobicity, a decrease in the mucus layer, as well as morphological evidence of villous injury. Although proteases themselves did not cause gut injury, the combination of pancreatic proteases with NAC caused more severe injury than NAC alone, suggesting that once the mucus barrier is impaired, luminal proteases can injure the now vulnerable gut. Because comparable levels of gut injury caused by systemic insults are associated with gut-induced lung injury, which is mediated by biologically active factors in mesenteric lymph, we next tested whether this local model of gut injury would produce active mesenteric lymph or lead to lung injury. It did not, suggesting that gut injury by itself may not

    Michael Griesser

    Full Text Available One of the main techniques for recognizing individuals in avian field research is marking birds with plastic and metal leg rings. However, in some species individuals may react negatively to rings, causing leg injuries and, in extreme cases, the loss of a foot or limb. Here, we report problems that arise from ringing and illustrate solutions based on field data from Brown Thornbills (Acanthiza pusilla (2 populations, Siberian Jays (Perisoreus infaustus and Purple-crowned Fairy-wrens (Malurus coronatus. We encountered three problems caused by plastic rings: inflammations triggered by material accumulating under the ring (Purple-crowned Fairy-wrens, contact inflammations as a consequence of plastic rings touching the foot or tibio-tarsal joint (Brown Thornbills, and toes or the foot getting trapped in partly unwrapped flat-band colour rings (Siberian Jays. Metal rings caused two problems: the edges of aluminium rings bent inwards if mounted on top of each other (Brown Thornbills, and too small a ring size led to inflammation (Purple-crowned Fairy-wrens. We overcame these problems by changing the ringing technique (using different ring types or larger rings, or using different adhesive. Additionally, we developed and tested a novel, simple technique of gluing plastic rings onto metal rings in Brown Thornbills. A review of studies reporting ring injuries (N = 23 showed that small birds (35 g tend to get rings stuck over their feet. We give methodological advice on how these problems can be avoided, and suggest a ringing hazard index to compare the impact of ringing in terms of injury on different bird species. Finally, to facilitate improvements in ringing techniques, we encourage online deposition of information regarding ringing injuries of birds at a website hosted by the European Union for Bird Ringing (EURING.

  16. The burn wound inflammatory response is influenced by midazolam. (United States)

    Babcock, George F; Hernandez, Laura; Yadav, Ekta; Schwemberger, Sandy; Dugan, Amy


    Burn patients requiring hospitalization are often treated for anxiety with benzodiazepines (BDZs). Benzodiazepines are reported to influence immune system function. Immune system alterations are a major cause of burn-induced mortality. We wanted to determine whether the BDZ, midazolam given daily at an anxiolytic dose, had any influence on the burn injury-induced inflammatory response in the blood and wound. Mice received a 15% total body surface area flame burn and received either midazolam 1 mg/kg i.p. or saline 0.1 ml daily. Blood and skin wounds were harvested 24 h after injection on post-burn day 2, 3, 7, or 8. Mice treated with midazolam had significantly lower serum IL-1β (p=0.002), TNF-α (p=0.002), IL-6 (p=0.016), IL-10 (p=0.009), and TGF-β (p=0.004) than saline-treated mice, with little impact on serum chemokine levels. In the wound, TNF-α and IL-10 were the only cytokines significantly influenced by the drug, being lower (p=0.018) and higher (p=0.006), respectively. The chemokines in the wound influenced significantly by midazolam were MIP-1α, MIP-1β, and MIP-2 while MCP-1 and KC were not. There were more inflammatory cells at the burn wound margin in midazolam-treated mice on post-burn day 3. Although serum nitrate/nitrite was significantly increased by midazolam (p=0.03), both eNOS and iNOS mRNA expression in the wound were similar to the saline group. We found that midazolam given daily after burn injury significantly influenced the inflammatory response. The clinical implications of these findings on wound healing and shock following burn injury, especially larger burns, deserve further investigation.

    Emami, Seyed-Abolhassan; Motevalian, Seyed Abbas; Momeni, Mahnoush; Karimi, Hamid


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

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

  20. MicroRNA dysregulation in Spinal Cord Injury: causes, consequences and therapeutics

    Directory of Open Access Journals (Sweden)

    Manuel eNieto-Díaz


    Full Text Available Trauma to the spinal cord causes permanent disability to more than 180,000 people every year worldwide. The initial mechanical damage triggers a complex set of secondary events involving the neural, vascular, and immune systems that largely determine the functional outcome of the spinal cord injury (SCI. Cellular and biochemical mechanisms responsible for this secondary injury largely depend on activation and inactivation of specific gene programs. Recent studies indicate that microRNAs function as gene expression switches in key processes of the SCI. Microarray data from rodent contusion models reveal that SCI induces changes in the global microRNA expression patterns. Variations in microRNA abundance largely result from alterations in the expression of the cells at the damaged spinal cord. However, microRNA expression levels after SCI are also influenced by the infiltration of immune cells to the injury site and the death and migration of specific neural cells after injury. Evidences on the role of microRNAs in the SCI pathophysiology have come from different sources. Bioinformatic analysis of microarray data has been used to identify specific variations in microRNA expression underlying transcriptional changes in target genes, which are involved in key processes in the SCI. Direct evidences on the role of microRNAs in SCI are scarcer, although recent studies have identified several microRNAs (miR-21, miR/486, miR-20 involved in key mechanisms of the SCI such as cell death or astrogliosis, among others. From a clinical perspective, different evidences make clear that microRNAs can be potent therapeutic tools to manipulate cell state and molecular processes in order to enhance functional recovery. The present article reviews the actual knowledge on how injury affects microRNA expression and the meaning of these changes in the SCI pathophysiology, to finally explore the clinical potential of microRNAs in the SCI.

    Vitarelli, Antonio; Divenuto, Lucia; Palminteri, Enzo; Lorusso, Giovanni; Pagliarulo, Arcangelo


    Urethral injuries due to penile prosthesis implant represent a rare complication of the intervention to position penile prosthesis, but unfortunately scientific literature about this is poor. This rare complication may occur during surgery and in the postoperative period, both early and late. It recognizes a variety of causes that may include anatomical or functional conditions, for example cavernosal fibrosis or outcomes of inflammations or previous urethral lesions and pathological sensibility due to diabetic neuropathy or other forms of neuropathy including those from spinal cord injury or myelopathy. This review evaluates the possible predisposing conditions, the clinical presentations, and the devices in the surgical procedures to use to minimize the risk of onset of this lesions and the measures to take if they occur.

    Trauma related injuries of permanent teeth occur frequently and are the most pressing issue the dentists are facing today. In different age groups the same type of trauma affects the teeth with different frequencies. For instance, accident related dental trauma in children and adults affected permanent teeth in 30% and deciduous teeth in 20%, respectively. It should also be noted that front teeth are more susceptible to traumatic injuries compared to the incisors. Upper front teeth were injured in 72% of cases, while lower central, upper lateral incisors, canines and premolars only in 6-8%. The severity of dental injury depends on the type and extent of the trauma. Dental injury can be result of either direct or indirect trauma. A strong, «fast as lightning» impact most often affects the dental crown. A weak and dull impact (thump) extends toward the root apical direction resulting in avulsion of the tooth and root fracture. Dental injury caused by trauma has been always considered as an emergency condition. It requires prompt complex treatment methods from maintaining pulp vitality to tooth extraction option. Treatment plan always depends on the type and severity of the injury and on current clinical condition of tooth. In all cases, the combined treatment includes: care of visible wound, fixation of teeth, performance of surgical manipulations, determining of the need of endodontic treatment, restorations and orthodontic consultation. The recorded clinical cases include descriptions of dental injuries of various types, as well as performed diagnostic and treatment procedures. In both cases root was fractured by impact. In Clinical Case 1 the tooth 2.1 vertical partial displacement of the tooth (extrusion) with root fracture in the apical third was observed; Clinical Case 2 - 1.1 dental root fracture in its middle third and vertical extrusion. Treatment strategy is dictated by pulp condition (Assessment of pulp vitality and status). In both cases, the

    Juliann G. Kiang


    Full Text Available Exposure to ionizing radiation alone (RI or combined with traumatic tissue injury (CI is a crucial life-threatening factor in nuclear and radiological events. In our laboratory, mice exposed to 60Co-γ-photon radiation (9.5 Gy, 0.4 Gy/min, bilateral followed by 15% total-body-surface-area skin wounds (R-W CI or burns (R-B CI experienced an increment of ≥18% higher mortality over a 30-day observation period compared to RI alone. CI was accompanied by severe leukocytopenia, thrombocytopenia, erythropenia, and anemia. At the 30th day after injury, numbers of WBC and platelets still remained very low in surviving RI and CI mice. In contrast, their RBC, hemoglobin, and hematocrit were recovered towards preirradiation levels. Only RI induced splenomegaly. RI and CI resulted in bone-marrow cell depletion. In R-W CI mice, ghrelin (a hunger-stimulating peptide therapy increased survival, mitigated body-weight loss, accelerated wound healing, and increased hematocrit. In R-B CI mice, ghrelin therapy increased survival and numbers of neutrophils, lymphocytes, and platelets and ameliorated bone-marrow cell depletion. In RI mice, this treatment increased survival, hemoglobin, and hematocrit and inhibited splenomegaly. Our novel results are the first to suggest that ghrelin therapy effectively improved survival by mitigating CI-induced leukocytopenia, thrombocytopenia, and bone-marrow injury or the RI-induced decreased hemoglobin and hematocrit.

  4. Mole gun injury. (United States)

    Pistré, V; Rezzouk, J


    A mole gun is a weapon, which is used to trap and kill moles. This report provides an overview of the state of knowledge of mole gun injuries, comparable to blast injuries caused by fireworks, explosive or gunshot. Over a 2-year period, the authors reported their experience with ten hand injuries caused by mole gun. Radial side of the hand was often concerned, particularly the thumb. The authors explain their choices in the management of such lesions. Surgery was performed primarily and a large debridement currently seemed to offer the best outcome for the patient. Blast, crush, burns and lacerations may explain the higher rate of amputation to the digits. A long period of physiotherapy, specifically of the hand, was needed before the patient could return to work. This ballistic hand trauma encountered by surgeons requires knowledge and understanding of these injuries. It should be in accordance with firearms law because of severe injuries encountered and possible lethal wounds.

  5. Defining the cause of death in hospitalised patients with acute kidney injury.

    Nicholas M Selby

    Full Text Available BACKGROUND: The high mortality rates that follow the onset of acute kidney injury (AKI are well recognised. However, the mode of death in patients with AKI remains relatively under-studied, particularly in general hospitalised populations who represent the majority of those affected. We sought to describe the primary cause of death in a large group of prospectively identified patients with AKI. METHODS: All patients sustaining AKI at our centre between 1(st October 2010 and 31(st October 2011 were identified by real-time, hospital-wide, electronic AKI reporting based on the Acute Kidney Injury Network (AKIN diagnostic criteria. Using this system we are able to generate a prospective database of all AKI cases that includes demographic, outcome and hospital coding data. For those patients that died during hospital admission, cause of death was derived from the Medical Certificate of Cause of Death. RESULTS: During the study period there were 3,930 patients who sustained AKI; 62.0% had AKI stage 1, 20.6% had stage 2 and 17.4% stage 3. In-hospital mortality rate was 21.9% (859 patients. Cause of death could be identified in 93.4% of cases. There were three main disease categories accounting for three quarters of all mortality; sepsis (41.1%, cardiovascular disease (19.2% and malignancy (12.9%. The major diagnosis leading to sepsis was pneumonia, whilst cardiovascular death was largely a result of heart failure and ischaemic heart disease. AKI was the primary cause of death in only 3% of cases. CONCLUSIONS: Mortality associated with AKI remains high, although cause of death is usually concurrent illness. Specific strategies to improve outcomes may therefore need to target not just the management of AKI but also the most relevant co-existing conditions.

  6. Management of burn wounds. (United States)

    Schiestl, Clemens; Meuli, Martin; Trop, Marija; Neuhaus, Kathrin


    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.

  7. Serotonin syndrome caused by minimum doses of SSRIS in a patient with spinal cord injury


    Satoh, Koichiro; Takano, Shizuko; Onogi, Takashi; Ohtsuki, Koji; Kobayashi, Toshio


    There have been only a few reports of serotonin syndrome developing after mono-therapy with a selective serotonin reuptake inhibitor (SSRI). We report a case of serotonin syndrome caused by long-term therapy with fluvoxamine prior to treatment with paroxetine. An 18-year-old man with spinal cord injury (SCI) at thoracic level 2-3 presented with onset of serotonin syndrome after taking fluvoxamine (50 mg per day) for 8 weeks prior to treatment with paroxetine (10 mg per day) for 6 days. He had...

  8. Acute cigarette smoke exposure causes lung injury in rabbits treated with ibuprofen

    Energy Technology Data Exchange (ETDEWEB)

    Witten, M.L.; Lemen, R.J.; Quan, S.F.; Sobonya, R.E.; Magarelli, J.L.; Bruck, D.C.


    We studied lung clearance of aerosolized technetium-labeled diethylenetriamine pentaacetic acid (/sup 99m/TcDTPA), plasma concentrations of 6-keto-PGF1 alpha and thromboxane B2, and pulmonary edema as indices of lung injury in rabbits exposed to cigarette smoke (CSE). Forty-six rabbits were randomly assigned to 4 groups: control sham smoke exposure (SS, N = 9), sham smoke exposure ibuprofen-pretreated (SS-I, N = 10), CSE (N = 9), sham smoke exposure ibuprofen-pretreated (SS-I, N = 10), CSE (N = 9), and CSE ibuprofen-pretreated (CSE-I, N = 19). Ibuprofen (cyclooxygenase eicosanoid inhibitor) was administered as a single daily intramuscular injection (25 mg/kg) for 7 days before the experiment. Cigarette or sham smoke was delivered by syringe in a series of 5, 10, 20, and 30 tidal volume breaths with a 15-min counting period between each subset of breaths to determine /sup 99m/TcDTPA biological half-life (T1/2). In the ibuprofen pretreated group, CSE caused significant decreases in /sup 99m/TcDTPA T1/2 and dynamic lung compliance. Furthermore, these changes in lung function were accompanied by severe injury to type I alveolar cell epithelium, pulmonary edema, and frequently death of the rabbits. These findings suggest that inhibition of the cyclooxygenase pathway before CSE exacerbates lung injury in rabbits.

    Tobin, Grainne A McMahon; Zhang, Jun; Goodwin, David; Stewart, Sharron; Xu, Lin; Knapton, Alan; González, Carlos; Bancos, Simona; Zhang, Leshuai; Lawton, Michael P; Enerson, Bradley E; Weaver, James L


    Previously we found that regulation of eNOS is an important part of the pathogenic process of Drug-induced vascular injury (DIVI) for PDE4i. The aims of the current study were to examine the phosphorylation of eNOS in mesentery versus aorta at known regulatory sites across DIVI-inducing drug classes and to compare changes across species. We found that phosphorylation at S615 in rats was elevated 35-fold 2 hr after the last dose of CI-1044 in mesentery versus 3-fold in aorta. Immunoprecipitation studies revealed that many of the upstream regulators of eNOS activation were associated with eNOS in 1 or more signalosome complexes. Next rats were treated with drugs from 4 other classes known to cause DIVI. Each drug was given alone and in combination with SIN-1 (NO donor) or L-NAME (eNOS inhibitor), and the level of eNOS phosphorylation in mesentery and aorta tissue was correlated with the extent of vascular injury and measured serum nitrite. Drugs or combinations produced altered serum nitrite levels as well as vascular injury score in the mesentery. The results suggested that phosphorylation of S615 may be associated with DIVI activity. Studies with the species-specific A2A adenosine agonist CI-947 in rats versus primates showed a similar pattern.

  10. Why most traumatic brain injuries are not caused by linear acceleration but skull fractures are.

    Directory of Open Access Journals (Sweden)

    Svein eKleiven


    Full Text Available Injury statistics have found the most common accident situation to be an oblique impact. An oblique impact will give rise to both linear and rotational head kinematics. The human brain is most sensitive to rotational motion. The bulk modulus of brain tissue is roughly five to six orders of magnitude larger than the shear modulus so that for a given impact it tends to deform predominantly in shear. This gives a large sensitivity of the strain in the brain to rotational loading and a small sensitivity to linear kinematics. Therefore, rotational kinematics should be a better indicator of traumatic brain injury risk than linear acceleration. To illustrate the difference between radial and oblique impacts, perpendicular impacts through the center of gravity of the head and 45o oblique impacts were simulated. It is obvious that substantially higher strain levels in the brain are obtained for an oblique impact, compared to a corresponding perpendicular one, when impacted into the same padding using an identical impact velocity. It was also clearly illustrated that the radial impact causes substantially higher stresses in the skull with an associated higher risk of skull fractures, and traumatic brain injuries secondary to those.

  11. Both the H2S biosynthesis inhibitor aminooxyacetic acid and the mitochondrially targeted H2S donor AP39 exert protective effects in a mouse model of burn injury. (United States)

    Ahmad, Akbar; Szabo, Csaba


    Hydrogen sulfide (H2S) exerts beneficial as well as deleterious effects in various models of critical illness. Here we tested the effect of two different pharmacological interventions: (a) inhibition of H2S biosynthesis using the cystathionine-beta-synthase (CBS)/cystathionine-gamma-lyase (CSE) inhibitor aminooxyacetic acid (AOAA) and the mitochondrially targeted H2S donor [10-oxo-10-[4-(3-thioxo-3H-1,2-dithiol-5-yl)phenoxy]decyl]triphenyl-phosphonium (AP39). A 30% body surface area burn injury was induced in anesthetized mice; animals were treated with vehicle, AOAA (10mg/kg i.p. once or once a day for 6days), or AP39 (0.3mg/kg/day once or once a day for 6days). In two separate groups, animals were sacrificed, at 24h post-burn or on Day 7 post-burn, blood and lungs were collected and the following parameters were evaluated: myeloperoxidase (MPO) and malondialdehyde (MDA) in lung homogenates, plasma cytokines (Luminex analysis) and circulating indicators of organ dysfunction (Vetscan analysis). Lung MPO levels (an index of neutrophil infiltration) and MDA levels (an index of oxidative stress) were significantly increased in response to burn injury both at 24h and at 7days; both AOAA and AP39 attenuated these increases. From a panel of inflammatory cytokines (TNFα, IL-1β, IL-6, IL-10, MCP-1, MIP-2, VEGF and IFNγ) in the plasma, IL-6 and IL-10 levels were markedly elevated at 24h and VEGF was slightly elevated. IL-6 remained highly elevated at 7days post-burn while IL-10 levels decreased, but remained slightly elevated over baseline 7days post-burn. The changes in cytokine levels were attenuated both by AP39 and AOAA at both time points studied. The burn-induced increases in the organ injury markers ALP and ALT, amylase and creatinine were reduced by both AOAA and AP39. We conclude that both H2S biosynthesis inhibition (using AOAA) and H2S donation (using AP39) suppresses inflammatory mediator production and reduces multi-organ injury in a murine model of burn

    Mohammad Mehdi Soltan Dallal


    Full Text Available Background: Burns and its complications are regarded as a major problem in the society. Skin injuries resulted from ultraviolet radiation, radioactivity, electricity or chemicals as well as respiratory damage from smoke inhalation are considered burns. This study aimed to determine the epidemiology and outcome of burn patients admitted to Motahari Hospital, Tehran, Iran. Methods: Two hundred patients with second-degree burns admitted to Motahari Referral Center of Burn in Tehran, Iran. They were studied during a period of 12 months from May 2012 to May 2013. During the first week of treatment swabs were collected from the burn wounds after cleaning the site with sterile normal saline. Samples were inoculated in blood agar and McConkey agar, then incubation at 37 C for 48 hours. Identification was carried out according to standard conventional biochemical tests. Treatment continued up to epithelial formation and wound healing. Results of microbial culture for each patient was recorded. Healing time of the burn wounds in patients was recorded in log books. Chi-square test and SPSS Software v.19 (IBM, NY, USA were used for data analysis. Results: Our findings indicate that the most causes of burns are hot liquids in 57% of cases and flammable liquid in 21% of cases. The most cases of burns were found to be in the range of 21 to 30 percent with 17.5% and 7% in male and female respectively. Gram-negative bacteria were dominated in 85.7% and among them pseudomonas spp. with 37.5% were the most common cause of infected burns, followed by Enterobacter, Escherichia coli, Staphylococcus aureus, Acinetobacter and Klebsiella spp. Conclusion: The results of this study showed that the most cause of burns in both sex is hot liquid. Men were more expose to burn than women and this might be due to the fact that men are involved in more dangerous jobs than female. Pseudomonas aeruginosa was the most common organism encountered in burn infection.

    Background Organophosphate poisoning is an important health problem in developing countries which causes death mainly by inducing acute lung injury.In this study,we examined the effects of penehyclidine hydrochloride (PHC),a selective M-receptor inhibitor,on dichlorvos-induced acute lung injury in swine.Methods Twenty-two female swines were randomly divided into control (n=5),dichlorvos (n=6),atropine (n=6),and PHC (n=5) groups.Hemodynamic data,extravascular lung water index (EVLWI),and pulmonary vascular permeability index (PVPI) were monitored; blood gas analysis and acetylcholinesterase (AchE) levels were measured.PaO2/FiO2,cardiac index (Cl),and pulmonary vascular resistance indices (PVRI) were calculated.At termination of the study,pulmonary tissue was collected for ATPase activity determination and wet to dry weight ratio (W/D) testing 6 hours post-poisoning.TUNEL assay,and Bax,Bcl-2,and caspase-3 expression were applied to pulmonary tissue,and histopathology was observed.Results After poisoning,PHC markedly decreased PVRI,increased CI more effectively than atropine.Anticholinergic treatment reduced W/D,apoptosis index (AI),and mitigated injury to the structure of lung; however,PHC reduced AI and caspase-3 expression and improved Bcl-2/Bax more effectively than atropine.Atropine and PHC improved ATPase activities; a significant difference between groups was observed in Ca2+-ATPase activity,but not Na+-K+-ATPase activity.Conclusions The PHC group showed mild impairment in pathology,less apoptotic cells,and little impact on cardiac function compared with the atropine group in dichlorvos-induced acute lung injury.

    Full Text Available Children are a vulnerable to burns, an injury, which is often preventable. A study of the profile of cases of children admitted for burns will provide background information to suggest locally doable preventive strategies as well as supply basic information for future reference. We studied the records of 62 children aged 0-16 years, admitted for burns, at the University of Benin Teaching Hospital, Benin City, between January 2002 and December 2006. There were 34 male and 28 female children. Children under three years constituted 56.5%. Whereas the leading cause of burns in all the children was flame burns from kerosene explosions (52%, scalds were responsible for 68.6% of cases in those under three. The extent of burn injury ranged from 6 to 50% and most of them presented late. 64.6% were discharged within three weeks. Wound sepsis and post burn contractures were the most frequently encountered complications (19.4% and 9.7% respectively. There were two deaths (3.2% related to sepsis. Particular attention to burn safety precautions in children (especially, in the> 3 years age group, safer storage and dispensing of combustible chemicals particularly petroleum products is advocated. Fire safety awareness, correct first aid measures and early presentation in the hospital will reduce morbidity and mortality. Early physiotherapy and splinting strategies will reduce contractures. There is the need locally for the establishment of specialized burn centres both to treat these children and to stimulate interest in burn management.

  16. Chemical burns--an historical comparison and review of the literature. (United States)

    Hardwicke, Joseph; Hunter, Thomas; Staruch, Robert; Moiemen, Naiem


    Chemical burns represent a small proportion of cutaneous burn with an incidence of up to 10.7%, but have been reported to account for up to 30% of all burn deaths. A review of the literature shows incidences ranging from 2.4% to 10.7%, with a substantial predominance in males. Adult patients with a burn referred to our Regional Burns Centre, over an eight-year period, were identified. 185 chemical burns were recorded (7.9%). The mean age of patient was 40 years (range 16-81 years) and male to female ratio was 6.4:1. Over three-quarters of chemical injuries occurred in the domestic or industrial setting. Acids caused 26% of all chemical burns and alkalis caused 55%. A previous study from the same centre highlights a change in the demographics of chemical burn over the last 25 years. The proportion of chemical burns has risen from 2.7% to 7.9%. Chemical burns occurring in an industrial setting, have dropped, whilst the number of domestic chemical burns has increased by over three times. This change reflects the improved industrial health and safety policy in recent years. The move from the industrial setting to the domestic has implications for future regulations.

  18. Severe metabolic acidosis following assault chemical burn. (United States)

    Roock, Sophie D; Deleuze, Jean-Paul; Rose, Thomas; Jennes, Serge; Hantson, Philippe


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

    Full Text Available The mechanical harvesting causes injuries on seeds and may affect their quality. Different threshing mechanisms and their adjustments may also affect the intensity of impacts that machines cause on seeds. So, this study aimed at diagnosing and evaluating the effect of two combines: the first one with a threshing system of axial flow and the other one with a threshing system of tangential flow, under adjustments of concave opening (10 mm, 30 mm and 10 mm for a combine with axial flow and 3.0 mm, 15 mm and 3.0 mm for a combine with tangential flow and three cylinder rotations on the quality of soybean seeds harvested at two moisture contents. Soybean seeds of cultivar 'ND 4910' were harvested at 16.6% moisture (mid - morning and 13.7% moisture in the afternoon. The seeds quality was evaluated by germination tests, germination speed index (GSI, germination rate, moisture content, percentage of purity and vigor by tetrazolium test. Despite the combine, the results showed that the mechanical injury has most reduced seeds quality, at 16.6% moisture content, concave opening of 30 mm (axial and 10 mm (tangential and cylinder rotation of 1100 rpm (axial and 1000 (tangential, both with the highest rotations used. The combine with tangential flow had the highest degree of seeds purity. When seeds moisture content at harvest was close to 13.7%, there was the highest seed injury, while, at 16.6%, there was the highest number of crushed soybeans, regardless the combine adjustment.

    The goal of this study was to examine the clinical course of 60-GHz millimeter-wave induced damages to the rabbit eye and to report experimental conditions that allow reproducible induction of these injuries. The eyes of pigmented rabbits (total number was 40) were irradiated with 60-GHz millimeter-waves using either a horn antenna or one of two lens antennas (6 and 9 mm diameter; phi6, phi9) Morphological changes were assessed by slit-lamp microscopy. Additional assessments included corneal fluorescein staining, iris fluorescein angiography, and lens epithelium light microscopy. Under the standardized eye-antenna positioning, the three antennas caused varying damages to the eyelids or eyeglobes. The most reproducible injuries without concurrent eyelid edema and corneal desiccation were achieved using the phi6 lens antenna: irradiation for 6 min led to an elevation of the corneal surface temperature (reaching 54.2 +/- 0.9 degrees C) plus corneal edema and epithelial cell loss. Furthermore, mitotic cells appeared in the pupillary area of the lens epithelium. Anterior uveitis also occurred resulting in acute miosis (from 6.6 +/- 1.4 to 2.2 +/- 1.4 mm), an increase in flares (from 6.7 +/- 0.9 to 334.3 +/- 130.8 photons per second), and iris vasodilation or vessel leakage. These findings indicate that the three types of millimeter-wave antennas can cause thermal injuries of varying types and levels. The thermal effects induced by millimeter-waves can apparently penetrate below the surface of the eye.

  3. Serious axillary nerve injury caused by subscapular artery compression resulting from use of backpacks. (United States)

    Haninec, Pavel; Mencl, Libor; Bačinský, Peter; Kaiser, Radek


    A palsy of the brachial plexus elements caused by carrying a heavy backpack is a very rare injury usually occurring in soldiers or hikers, and recovery is usually spontaneous. We describe here the case of male civilian presenting with an isolated serious axillary nerve palsy associated with chronic backpack use. During the surgery, a dumbbell-shaped neuroma-in-continuity was found which was caused by direct pressure from the subscapular artery. After resection of the neuroma, a nerve graft from the sural nerve was used to reconstruct the nerve. Reinnervation was successful and the patient was able to abduct his arm to its full range, with full muscle strength, within 24 months.

  4. Protective effect of natural flavonoids on rat peritoneal macrophages injury caused by asbestos fibers. (United States)

    Kostyuk, V A; Potapovich, A I; Speransky, S D; Maslova, G T


    Exposure of macrophages to asbestos fibers resulted in enhancement of the production of oxygen radicals, determined by a lucigenin enhanced chemiluminescence (LEC) assay, a formation of thiobarbituric acid reactive substances (TBARS), a LDH release into the incubation mixture, and a rapid lysis of the cells. Rutin (Rut) and quercetin (Qr) were effective in inhibiting LEC, TBARS formation, and reducing peritoneal macrophages injury caused by asbestos. The concentrations pre-treatment of antioxidants that were required to prevent the injury of peritoneal macrophages caused by asbestos by 50% (IC50) were 90 microM and 290 microM for Qr and Rut, respectively. Both flavonoids were found to be oxidized during exposure of peritoneal macrophages to asbestos and the oxidation was SOD sensitive. The efficacy of flavonoids as antioxidant agents as well as superoxide ion scavengers was also evaluated using appropriate model systems, and both quercetin and rutin were found to be effective in scavenging O2.-. These findings indicate that flavonoids are able to prevent the respiratory burst in rat peritoneal macrophages exposed to asbestos at the stage of activated oxygen species generation, mainly as superoxide scavengers. On the basis of this study it was concluded that natural flavonoids quercetin and rutin would be promising drug candidates for a prophylactic asbestos-induced disease.

  5. Injury/Fatality-Causing Incidents Involving the Rearward Movement of Agricultural Machinery: Types, Causes, and Preventive Measures

    Shawn G. Ehlers


    Full Text Available The research reported here sought to more fully understand the types and causative factors of injury/fatality incidents resulting from the rearward-movement of tractors and other self-propelled agricultural machinery, with the view that such findings might lead to the development, improvement, and/or better utilization of safety procedures, design principles, and technologies that would prevent—or at least markedly reduce—their occurrence. Thus, the scope of this study focused only on rearward-travel (not mechanical malfunction incidents, and principally on agricultural equipment (although cases involving similar equipment in industrial or construction settings were also drawn upon. Applying these two criteria, a search of published and online sources uncovered more than 100 documented cases, 35 of which could clearly be identified as rearward-movement incidents, of which 28 (80% were fatal. Each of these 35 cases were then assessed, based on the type of machine, type of worksite, and type/description of incident (i.e., ‘scenario’, which fell into one of three distinct categories or classifications—(1 co-worker run over/crushed/otherwise injured because operator loses visual contact with co-worker; (2 bystander run over/crushed/otherwise injured because operator is unaware of bystander’s presence; and (3 operator run over/crushed/otherwise injured because operator loses visual contact with, or is unaware of, a stationary object or a hazard. Then, from each scenario, a representative incident (i.e., case study was selected for a more in-depth analysis. The collective findings, from these three case studies and all 35 machinery rearward-movement incidents, were as follows: (1 The ‘victim’ could be the machine operator as well as a co-worker or a bystander; (2 The specific site of the co-worker or bystander injury/fatality was at the base of the machine’s rear tires or tracks, at the hitching point, or behind a towed implement; (3

  6. Bronchoscopy-derived correlates of lung injury following inhalational injuries: a prospective observational study.

    Directory of Open Access Journals (Sweden)

    Samuel W Jones

    Full Text Available BACKGROUND: Acute lung injury (ALI is a major factor determining morbidity following burns and inhalational injury. In experimental models, factors potentially contributing to ALI risk include inhalation of toxins directly causing cell damage; inflammation; and infection. However, few studies have been done in humans. METHODS: We carried out a prospective observational study of patients admitted to the NC Jaycees Burn Center who were intubated and on mechanical ventilation for burns and suspected inhalational injury. Subjects were enrolled over an 8-month period and followed till discharge or death. Serial bronchial washings from clinically-indicated bronchoscopies were collected and analyzed for markers of cell injury and inflammation. These markers were compared with clinical markers of ALI. RESULTS: Forty-three consecutive patients were studied, with a spectrum of burn and inhalation injury severity. Visible soot at initial bronchoscopy and gram negative bacteria in the lower respiratory tract were associated with ALI in univariate analyses. Subsequent multivariate analysis also controlled for % body surface area burns, infection, and inhalation severity. Elevated IL-10 and reduced IL-12p70 in bronchial washings were statistically significantly associated with ALI. CONCLUSIONS: Independently of several factors including initial inhalational injury severity, infection, and extent of surface burns, high early levels of IL-10 and low levels of IL-12p70 in the central airways are associated with ALI in patients intubated after acute burn/inhalation injury. Lower airway secretions can be collected serially in critically ill burn/inhalation injury patients and may yield important clues to specific pathophysiologic pathways.

    Burns and thermal injuries related with magnetic resonance imaging (MRI) are rare. Previous literature indicates that medical devices with cable, cosmetics or tattoo are known as risk factors for burns and thermal injuries. However, there is no report of MRI-related burns in Korea. Herein, we reported a case of deep second degree burn after MRI in a 38-year-old female patient with multiple uterine leiomyomas including some that were large and degenerated. The large uterine leiomyoma-induced protruded anterior abdominal wall in direct contact with the body coil during MRI was suspected as the cause of injury, by retrospective analysis. Therefore, awareness of MRI related thermal injury is necessary to prevent this hazard, together with extreme care during MRI.

    Ali Arhami Dolatabadi


    Full Text Available Abstract Background and Aim: Motor vehicle accidents are common cause of mortality, morbidity and disability. Human factors are principle cause for frequency of motor vehicle accident. In most studies, 52-40% lower limb injuries are trauma from a motorcycle accident. These accidents cause high financial cost and harm for society. Materials and Methods: In this study, patients with lower limb injuries referred to the hospital trauma ward of Imam Hussein were evaluated during one year. Questionnaire forms were designed and completed for patients then data of these forms was inserted in a database. The information was analyzed by statistical software SPSS 18. Results: from 766 patients with lower limb traumas which were examined and evaluated, 92 % were male and mean age of patients was 25± 12 years. 156 patients suffered from head and neck trauma and 134 persons had skin damage in addition to lower limb trauma. Injury to leg was most common injuries in lower leg and tibia shaft fracture was more frequent than lower bone fracture. Most injuries in pelvic trauma associated with fractures of the superior pubic ramus and coccyx bone. Seventy percent of related knee injuries included injury to patella and tibia plateau. The most observed injuries in ankle and foot were lateral malleolus fracture and lisferanc injuries. About 11 percent of patients were discharged from emergency room after primary management and other patients were admitted in hospital.Conclusion: Given the high incidence of lower extremity injuries, especially the leg, in the accident of motorcycle riders, procurement and construction of an efficient protective equipment, especially protective guard can be effective in reducing accidents.

    Full Text Available The aim of this study to analyse the occurrence of injuries in undergraduates of the Physical Education Course at the State University of Maringá. Types of injuries were diagnosed, the opinion of students and professors with regard to their probable causes was taken and the factors that could render injuries less damaging were identified. Research was carried out in the second semester of 1991 when 231 students were regularly enlisted. Data were collected by means of questionnaires for professors and for students. Forty injury cases were verified, 13 with males and 27 with females. The most common type of injury was bruises (55% followed by strain (18%. The inferior members were the most affected region. Judo was the subject in which the greatest number of injuries occurred. Students stated that salient probable causes were: agressivity of colleages in practical exercises (33% and defective sports facilities (25%. In the professors opinion, however, the two chief causes were: students’ distraction (20% and physical inability (20%. The establishment of an Internal Commission for the Prevention of Accidents has been suggested made up of professors, under graduate students and personnel of the Physical Education Department at the State University of Maringá. Its aims are to carry out a following up of this situation, to promote the prevention of injuries and to suggest possible improvements in the premises.

    S J Baruah


    Full Text Available Penile incarceration injury by heavy metallic ring is a rare genital injury. A man may place metal object for erotic or autoerotic purposes, for masturbation or increasing erection, and due to psychiatric disturbances are some of the reasons for a penile incarceration injury. The incarcerating injury results in reduced blood flow distal to the injury, leading to edema, ischemia, and sometimes gangrene. These injuries are divided into five grades and their treatment options are divided into four groups. Surgical techniques are reserved for the advanced grades (Grades IV and V. We describe an innovative surgical technique, which can be adopted in Grades II and III injuries.

    Eight burn wound sepsis patients, in which 6 cases were diagnosed as MODS and two as septic shock, were treated consecutively in our hospital from September 1997 to October 1998. The plasma concentration of IL-6, IL-8, TNFα and LPS were assayed before and after surgical intervention, as well as when the patients' vital signs became stable. The results showed: ①The patients' conditions abruptly deteriorated when the burn wound sepsis emerged;②The major cause related to burn wound sepsis was extensive burn injuries, with large areas of deep burn remaining open; ③Although wound swabs taken on admission revealed the presence of colonization by many pathogenic bacteria, Pseudomonas aeruginosa was one of the most frequent bacteria isolated from the subeschar tissue; ④The plasma concentrations of IL-6, IL-8, TNF and LPS before surgical intervention were significantly higher than that after surgical intervention (P<0.05) ;⑤The lowest level of the inflammatory mediators was observed when the patients' conditions became stable, as compared with before surgical intervention (P<0. 001).These findings suggest that the clinical characteristics of burn wound sepsis are abrupt deterioration of the general condition and prominent septic symptoms, often complicated by MODS. The main cause of burn wound sepsis is the presence of a large area of open deep burn wounds, which should be excised and covered early. LPS and pro-inflammatory mediators play an important role in the pathogenesis of burn wound sepsis. Although success in treating these patients is the result of appropriate application of multiple treatments, early, aggressive and thorough surgical excision of invasive burn infectious tissue and closure of wound play a crucial role in the successful treatment of patients complicated by burn wound sepsis. Other treatments are adjuvant but also important.

  13. Nerve injury-induced neuropathic pain causes disinhibition of the anterior cingulate cortex. (United States)

    Blom, Sigrid Marie; Pfister, Jean-Pascal; Santello, Mirko; Senn, Walter; Nevian, Thomas


    Neuropathic pain caused by peripheral nerve injury is a debilitating neurological condition of high clinical relevance. On the cellular level, the elevated pain sensitivity is induced by plasticity of neuronal function along the pain pathway. Changes in cortical areas involved in pain processing contribute to the development of neuropathic pain. Yet, it remains elusive which plasticity mechanisms occur in cortical circuits. We investigated the properties of neural networks in the anterior cingulate cortex (ACC), a brain region mediating affective responses to noxious stimuli. We performed multiple whole-cell recordings from neurons in layer 5 (L5) of the ACC of adult mice after chronic constriction injury of the sciatic nerve of the left hindpaw and observed a striking loss of connections between excitatory and inhibitory neurons in both directions. In contrast, no significant changes in synaptic efficacy in the remaining connected pairs were found. These changes were reflected on the network level by a decrease in the mEPSC and mIPSC frequency. Additionally, nerve injury resulted in a potentiation of the intrinsic excitability of pyramidal neurons, whereas the cellular properties of interneurons were unchanged. Our set of experimental parameters allowed constructing a neuronal network model of L5 in the ACC, revealing that the modification of inhibitory connectivity had the most profound effect on increased network activity. Thus, our combined experimental and modeling approach suggests that cortical disinhibition is a fundamental pathological modification associated with peripheral nerve damage. These changes at the cortical network level might therefore contribute to the neuropathic pain condition.

  14. Pain in burn patients. (United States)

    Latarjet, J; Choinère, M


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

    Pant, R; Manandhar, V; Wittgenstein, F; Fortney, J A; Fukushima, C


    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.

  16. Characterization of Feeding Injuries Caused by Ceresa nigripectus Remes Lenicov (Hemiptera: Membracidae) on Alfalfa Stems. (United States)

    Grosso, T P; Mercado, M I; Ponessa, G I; Conci, L R; Virla, E G


    Piercing-sucking insects cause mechanical and physiological injury to plants. Ceresa nigripectus Remes Lenicov is a pest of alfalfa in subtropical regions of South America and a carrier of the ArAWB phytoplasma. The aim of this study was to determine the feeding habits of this treehopper and to describe the effects of the feeding injuries on stem vascular tissues in alfalfa. Adults and nymphs of C. nigripectus inserted their stylets repeatedly girdling the stem. One week after feeding, alfalfa stems exhibited numerous feeding canals with salivary deposits, most of which reached the phloem. Two weeks after feeding, cortex and phloem cells next to the salivary sheath collapsed, mature tracheal elements became sparse and appeared with an increased cross-section area, and phenolic compounds increased in cells and cell walls compared to undamaged plants. Three weeks after feeding, an annular callus, formed by abnormal cell division and hypertrophy of preexisting cortex and vascular cambium cells, appeared immediately above the stem girdle. Parenchyma cells from the outer layers of the callus differentiated to form secondary anomalous amphicribal bundles in the wound. The aerial parts above the stem girdle eventually withered and died.

    Full Text Available Background: Developing countries have a high incidence of burn injuries, creating a formidable public health problem. The exact number of cases is difficult to determine: however in a country like India, with a population of over 1 billion, we would estimate 700,000 to 800,000 burn admissions annually. Objective: The study was done to investigate the epidemiology of various causations and their outcomes in terms of morbidity and mortality. Also, the effect of social stigma and cultural issues associated with burns on the victim and his family was assessed. Materials and Methods: All burn cases (n=412 admitted to the burns unit of M. Y. Hospital, Indore over a period of one year (2005-2006 were investigated. The data regarding sex, age predisposition, geographical origin, mode and nature of injury were obtained by questionnaire-interview with the patient themselves. Clinical assessment was done in the form of depth and extent of injury and complications. In case of mortality, again various factors like age, sex and cause of death were analyzed. The data was analyzed by SPSS 11.0 version. The interrelationship between various factors was studied using multivariate logistic regression analysis. Results: Burns were found more commonly in middle-aged groups. The incidence was more in females as an absolute number (70.3% as well as when stratified by age. Most burns were domestic, with cooking being the most prevalent activity. Flame (80.3% was the most common agent. Most of the cases of burn were accidental (67.7%. Moreover, the patients had third degree burn that leads to more mortality in our circumstances. Death occurred in more than one-half (62.3% of cases with septicaemia and disseminated intravascular coagulation (35.4% as the leading causes. When using logistic regression analysis, the outcome of the burn injury was significantly associated with degree, depth, extent and mode of injury. Conclusion: This series provides an overview of the most

  18. [The pain from burns]. (United States)

    Latarjet, J


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

    Akira Yabuki


    Full Text Available A 10-year-old spayed female Papillon weighing 4.0 kg presented with a history of persistent hematuria and pollakiuria. Concurrent bladder calculi, a mammary gland tumor, and nonazotemic early stage of chronic kidney disease with contracted kidneys were noted in this dog. The dog underwent cystectomy, unilateral mastectomy, and intraoperative renal biopsy. On the basis of histopathological analysis of renal biopsy results, it was suspected that renal injury of the dog was caused by persistent hypertension, and a follow-up examination revealed severe hypertension. The dog was treated with a combination of an angiotensin-converting enzyme inhibitor and calcium channel blocker. The treatment produced a good outcome in the dog, and there has been no progression of the chronic kidney disease for over 2 years.

The passage of electric current through the body is capable of producing a wide spectrum of injuries, including serious damage to the heart, brain, skin and muscles. Naked high-voltage electric cables negligently abandoned in residential, commercial and industrial areas are a recipe for disaster. This is a case report of a 5-year girl child who had bilateral lower limb gangrene followin...

  1. Human-Wildlife Conflicts in Nepal: Patterns of Human Fatalities and Injuries Caused by Large Mammals. (United States)

    Acharya, Krishna Prasad; Paudel, Prakash Kumar; Neupane, Prem Raj; Köhl, Michael


    Injury and death from wildlife attacks often result in people feeling violent resentment and hostility against the wildlife involved and, therefore, may undermine public support for conservation. Although Nepal, with rich biodiversity, is doing well in its conservation efforts, human-wildlife conflicts have been a major challenge in recent years. The lack of detailed information on the spatial and temporal patterns of human-wildlife conflicts at the national level impedes the development of effective conflict mitigation plans. We examined patterns of human injury and death caused by large mammals using data from attack events and their spatiotemporal dimensions collected from a national survey of data available in Nepal over five years (2010-2014). Data were analyzed using logistic regression and chi-square or Fisher's exact tests. The results show that Asiatic elephants and common leopards are most commonly involved in attacks on people in terms of attack frequency and fatalities. Although one-horned rhinoceros and bears had a higher frequency of attacks than Bengal tigers, tigers caused more fatalities than each of these two species. Attacks by elephants peaked in winter and most frequently occurred outside protected areas in human settlements. Leopard attacks occurred almost entirely outside protected areas, and a significantly greater number of attacks occurred in human settlements. Attacks by one-horned rhinoceros and tigers were higher in the winter, mainly in forests inside protected areas; similarly, attacks by bears occurred mostly within protected areas. We found that human settlements are increasingly becoming conflict hotspots, with burgeoning incidents involving elephants and leopards. We conclude that species-specific conservation strategies are urgently needed, particularly for leopards and elephants. The implications of our findings for minimizing conflicts and conserving these imperiled species are discussed.

  2. Niacinamide abrogates the organ dysfunction and acute lung injury caused by endotoxin. (United States)

    Kao, Shang-Jyh; Liu, Demeral David; Su, Chain-Fa; Chen, Hsing I


    Poly (ADP-ribose) synthabse (PARS) or polymerase (PARP) is a cytotoxic enzyme causing cellular damage. Niacinamide inhibits PARS or PARP. The present experiment tests the effects of niacinamide (NCA) on organ dysfunction and acute lung injury (ALI) following lipopolysaccharide (LPS). LPS was administered to anesthetized rats and to isolated rat lungs. In anesthetized rats, LPS caused systemic hypotension and increased biochemical factors, nitrate/nitrite (NOx), methyl guanidine (MG), tumor necrosis factoralpha (TNFalpha), and interleukin-1beta (IL-1beta). In isolated lungs, LPS increased lung weight (LW) to body weight ratio, LW gain, protein and dye tracer leakage, and capillary permeability. The insult also increased NOx, MG, TNFalpha, and IL-1beta in lung perfusate, while decreased adenosine triphosphate (ATP) content with an increase in PARP activity in lung tissue. Pathological examination revealed pulmonary edema with inflammatory cell infiltration. These changes were abrogated by posttreatment (30 min after LPS) with NCA. Following LPS, the inducible NO synthase (iNOS) mRNA expression was increased. NCA reduced the iNOS expression. Niacinamide exerts protective effects on the organ dysfunction and ALI caused by endotoxin. The mechanisms may be mediated through the inhibition on the PARP activity, iNOS expression and the subsequent suppression of NO, free radicals, and proinflammatory cytokines with restoration of ATP.

  3. Lung injury caused by greenstick fracture of the scapular body in a 6-year-old boy. (United States)

    Shin, Sung Jin; Wang, Sung Il; Kim, Jung Ryul


    Complications caused by a scapular body fracture are rare, and usually occur due to concomitant injuries or nonunion. Intrathoracic displacement of a fractured scapula has only been described in two reports involving adolescents. In this report, we describe a 6-year-old boy with a parenchymal lung injury caused by a greenstick fracture fragment of the scapular body after being struck by a dump truck. Three-dimensional CT (3D CT) scan showed an incomplete fractured fragment impaling the left lung parenchyma resulting in pneumothorax, parenchymal contusion, and pneumatocele in the left upper lobe. The patient underwent emergency open reduction of the scapular fracture and chest tube insertion. A rare subtype of scapular fracture with resultant fragment rotation and intrathoracic penetration can injure the lung parenchyma. To the best of our knowledge, lung injury caused by incomplete fracture of the scapula in patients younger than 10 years has not been reported previously.

    Full Text Available This study had the objective of evaluating the injuries caused by animals to young imbu tree (Spondias tuberosa Arruda plants in native and degraded Caatinga areas, between the years 1997 and 2002. One thousand imbu tree scions were planted, being 500 in a degraded Caatinga area at the community of Alto do Angico, Petrolina-PE, and 500 in a native Caatinga area at the Caatinga Experimental Station of Embrapa Tropical Semi-Arid, Petrolina-PE. At every 30 days after having planted the scions, data were collected regarding survival and injuries caused by animals to the plants. The results showed that goats are responsible for the reduction on survival rates and for the slow development of young imbu tree in the degraded Caatinga area. In the native Caatinga area, of the collared peccary (Tayassu tajacu and armadillo (Euphractus sexcinctus caused the highest injury levels.

  5. The efficacy of hair and urine toxicology screening on the detection of child abuse by burning. (United States)

    Hayek, Shady N; Wibbenmeyer, Lucy A; Kealey, Lyn Dee H; Williams, Ingrid M; Oral, Resmiye; Onwuameze, Obiora; Light, Timothy D; Latenser, Barbara A; Lewis, Robert W; Kealey, Gerald P


    Abuse by burning is estimated to occur in 1 to 25% of children admitted with burn injuries annually. Hair and urine toxicology for illicit drug exposure may provide additional confirmatory evidence for abuse. To determine the impact of hair and urine toxicology on the identification of child abuse, we performed a retrospective chart review of all pediatric patients admitted to our burn unit. The medical records of 263 children aged 0 to 16 years of age who were admitted to our burn unit from January 2002 to December 2007 were reviewed. Sixty-five children had suspected abuse. Of those with suspected abuse, 33 were confirmed by the Department of Health and Human Services and comprised the study group. Each of the 33 cases was randomly matched to three pediatric (0-16 years of age) control patients (99). The average annual incidence of abuse in pediatric burn patients was 13.7+/-8.4% of total annual pediatric admissions (range, 0-25.6%). Age younger than 5 years, hot tap water cause, bilateral, and posterior location of injury were significantly associated with nonaccidental burn injury on multivariate analysis. Thirteen (39.4%) abused children had positive ancillary tests. These included four (16%) skeletal surveys positive for fractures and 10 (45%) hair samples positive for drugs of abuse (one patient had a fracture and a positive hair screen). In three (9.1%) patients who were not initially suspected of abuse but later confirmed, positive hair test for illicit drugs was the only indicator of abuse. Nonaccidental injury can be difficult to confirm. Although inconsistent injury history and burn injury pattern remain central to the diagnosis of abuse by burning, hair and urine toxicology offers a further means to facilitate confirmation of abuse.

  6. Tiotropium bromide suppresses smoke inhalation and burn injury-induced ERK 1/2 and SMAD 2/3 signaling in sheep bronchial submucosal glands. (United States)

    Jacob, Sam; Zhu, Yong; Asmussen, Sven; Ito, Hiroshi; Herndon, David N; Enkhbaatar, Perenlei; Hawkins, Hal K; Cox, Robert A


    The effects of tiotropium bromide on ERK 1/2, SMAD 2/3 and NFκB signaling in bronchial submucosal gland (SMG) cells of sheep after smoke inhalation and burn injury (S + B) were studied. We hypothesized that tiotropium would modify intracellular signaling processes within SMG cells after injury. Bronchial tissues were obtained from uninjured (sham, n = 6), S + B injured sheep 48 h after injury (n = 6), and injured sheep nebulized with tiotropium (n = 6). The percentage (mean ± SD) of cells showing nuclear localization of phosphorylated ERK 1/2, pSMAD 2/3, and NFκB (p65) was determined by immunohistochemistry. Nuclear pERK 1/2 staining was increased in injured animals as compared to sham, (66 ± 20 versus 14 ± 9), p = 0.0022, as was nuclear pSMAD, 84 ± 10 versus 20 ± 10, p = 0.0022. There was a significant decrease in pERK 1/2 labeling in the tiotropium group compared to the injured group (31 ± 20 versus 66 ± 20, p = 0.013), and also a decrease in pSMAD labeling, 62 ± 17 versus 84 ± 10, p = 0.04. A significant increase for NFκB (p65) was noted in injured animals as compared to sham (73 ± 16 versus 7 ± 6, p = 0.0022). Tiotropium-treated animals showed decreased p65 labeling as compared to injured (35 ± 17 versus 74 ± 16, p = 0.02). The decrease in nuclear expression of pERK, pSMAD and NFκB molecules in SMG cells with tiotropium treatment is suggestive that their activation after injury is mediated in part through muscarinic receptors.

  7. Breviscapine reduces neuronal injury caused by traumatic brain injury insult: partly associated with suppression of interleukin-6 expression

    Directory of Open Access Journals (Sweden)

    Ling Jiang


    Full Text Available Breviscapine, extracted from the herb Erigeron breviscapus, is widely used for the treatment of cardiovascular diseases, cerebral infarct, and stroke, but its mechanism of action remains unclear. This study established a rat model of traumatic brain injury induced by controlled cortical impact, and injected 75 μg breviscapine via the right lateral ventricle. We found that breviscapine significantly improved neurobehavioral dysfunction at 6 and 9 days after injection. Meanwhile, interleukin-6 expression was markedly down-regulated following breviscapine treatment. Our results suggest that breviscapine is effective in promoting neurological behavior after traumatic brain injury and the underlying molecular mechanism may be associated with the suppression of interleukin-6.

    Ma, Shuo; Chen, Chong; Cao, Tingting; Bi, Yue; Zhou, Jicheng; Li, Xintao; Yu, Deqin; Li, Shuzhuang


    Multiple organ dysfunctional syndrome secondary to mechanical trauma (MT) has attracted considerable research attention. The heart is one of the most important organs of the body, and secondary cardiac insufficiency caused by MT seriously affects the quality of life. This study aims to investigate whether proanthocyanidin can alleviate myocardial injury and improve heart function in the process of MT leading to secondary cardiac insufficiency. Noble-Collip drum wasused to prepare MT model in rats. And myocardial apoptosis index was calculated after TUNEL staining. Ventricular intubation was employed to detect heart function. Changes in myocardial ultrastructure were observed using an electron microscope. ELISA was used to detect the content of TNF-α and reactive oxygen species generated from monocytes and cardiomyocytes. The changes in Ca2+ concentration in cardiomyocyte were observed by confocal microscope. Compared with trauma group, the administration group had a decreased apoptosis index of cardiomyocytes, and increased ±dp/dtmax. Meanwhile, proanthocyanidin can inhibit monocytes’ TNF-α production, and reduce plasma TNF-α concentration. Moreover, proanthocyanidin can attenuate the excessive oxidative stress reaction of cardiomyocyte, and inhibit calcium overload in cardiomyocytes. In conclusion, proanthocyanidin can effectively ease myocardial damage and improve cardiac function, through anti-inflammatory and antioxidant effects in secondary cardiac insufficiency caused by MT.

    Saima Aslam Bharwana


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

    Sepsis is the most common cause of acute respiratory distress syndrome, a severe lung inflammatory disorder with an elevated morbidity and mortality. Sepsis and acute respiratory distress syndrome involve the release of inflammatory mediators to the systemic circulation, propagating the cellular and molecular response and affecting distal organs, including the brain. Since it has been reported that sepsis and acute respiratory distress syndrome contribute to brain dysfunction, we investigated the brain-lung crosstalk using a combined experimental in vitro airway epithelial and brain cell injury model. Conditioned medium collected from an in vitro lipopolysaccharide-induced airway epithelial cell injury model using human A549 alveolar cells was subsequently added at increasing concentrations (no conditioned, 2%, 5%, 10%, 15%, 25%, and 50%) to a rat mixed brain cell culture containing both astrocytes and neurons. Samples from culture media and cells from mixed brain cultures were collected before treatment, and at 6 and 24 h for analysis. Conditioned medium at 15% significantly increased apoptosis in brain cell cultures 24 h after treatment, whereas 25% and 50% significantly increased both necrosis and apoptosis. Levels of brain damage markers S100 calcium binding protein B and neuron-specific enolase, interleukin-6, macrophage inflammatory protein-2, as well as matrix metalloproteinase-9 increased significantly after treating brain cells with ≥2% conditioned medium. Our findings demonstrated that human epithelial pulmonary cells stimulated with bacterial lipopolysaccharide release inflammatory mediators that are able to induce a translational clinically relevant and harmful response in brain cells. These results support a brain-lung crosstalk during sepsis and sepsis-induced acute respiratory distress syndrome. PMID:25135986

    Full Text Available Hippocampal injury-associated learning and memory deficits are frequent hallmarks of brain trauma and are the most enduring and devastating consequences following traumatic brain injury (TBI. Several reports, including our recent paper, showed that TBI brought on by a moderate level of controlled cortical impact (CCI induces immature newborn neuron death in the hippocampal dentate gyrus. In contrast, the majority of mature neurons are spared. Less research has been focused on these spared neurons, which may also be injured or compromised by TBI. Here we examined the dendrite morphologies, dendritic spines, and synaptic structures using a genetic approach in combination with immunohistochemistry and Golgi staining. We found that although most of the mature granular neurons were spared following TBI at a moderate level of impact, they exhibited dramatic dendritic beading and fragmentation, decreased number of dendritic branches, and a lower density of dendritic spines, particularly the mushroom-shaped mature spines. Further studies showed that the density of synapses in the molecular layer of the hippocampal dentate gyrus was significantly reduced. The electrophysiological activity of neurons was impaired as well. These results indicate that TBI not only induces cell death in immature granular neurons, it also causes significant dendritic and synaptic degeneration in pathohistology. TBI also impairs the function of the spared mature granular neurons in the hippocampal dentate gyrus. These observations point to a potential anatomic substrate to explain, in part, the development of posttraumatic memory deficits. They also indicate that dendritic damage in the hippocampal dentate gyrus may serve as a therapeutic target following TBI.

    Full Text Available Burn injuries are a huge public health issue for children throughout the world, with the majority occurring in developing countries. Burn injuries can leave a pediatric patient with severely debilitating and deforming contractures, which can lead to significant disability when left untreated. Rehabilitation is an essential and integral part of pediatric burn treatment. The aim of this article was to review the literature on pediatric burn rehabilitation from the Medline, CINAHL, and Web of Science databases. An attempt has been made to present the basic aspects of burn rehabilitation, provide practical information, and discuss the goals and conceptualization of rehabilitation as well as the development of rehabilitation philosophy and strategies.

  16. iNOS as a Driver of Inflammation and Apoptosis in Mouse Skeletal Muscle after Burn Injury: Possible Involvement of Sirt1 S-Nitrosylation-Mediated Acetylation of p65 NF-κB and p53 (United States)

    Yasukawa, Takashi; Ishimaru, Kazuhiro; Yasuhara, Shingo; Yu, Yong-Ming; Martyn, J. A. Jeevendra; Tompkins, Ronald. G.; Shimokado, Kentaro; Kaneki, Masao


    Inflammation and apoptosis develop in skeletal muscle after major trauma, including burn injury, and play a pivotal role in insulin resistance and muscle wasting. We and others have shown that inducible nitric oxide synthase (iNOS), a major mediator of inflammation, plays an important role in stress (e.g., burn)-induced insulin resistance. However, it remains to be determined how iNOS induces insulin resistance. Moreover, the interrelation between inflammatory response and apoptosis is poorly understood, although they often develop simultaneously. Nuclear factor (NF)-κB and p53 are key regulators of inflammation and apoptosis, respectively. Sirt1 inhibits p65 NF-κB and p53 by deacetylating these transcription factors. Recently, we have shown that iNOS induces S-nitrosylation of Sirt1, which inactivates Sirt1 and thereby increases acetylation and activity of p65 NF-κB and p53 in various cell types, including skeletal muscle cells. Here, we show that iNOS enhances burn-induced inflammatory response and apoptotic change in mouse skeletal muscle along with S-nitrosylation of Sirt1. Burn injury induced robust expression of iNOS in skeletal muscle and gene disruption of iNOS significantly inhibited burn-induced increases in inflammatory gene expression and apoptotic change. In parallel, burn increased Sirt1 S-nitrosylation and acetylation and DNA-binding capacity of p65 NF-κB and p53, all of which were reversed or ameliorated by iNOS deficiency. These results indicate that iNOS functions not only as a downstream effector but also as an upstream enhancer of burn-induced inflammatory response, at least in part, by Sirt1 S-nitrosylation-dependent activation (acetylation) of p65 NF-κB. Our data suggest that Sirt1 S-nitrosylation may play a role in iNOS-mediated enhanced inflammatory response and apoptotic change, which, in turn, contribute to muscle wasting and supposedly to insulin resistance after burn injury.

    Full Text Available Quorum Sensing and type III secretion system play an important role in the virulence of Pseudomonas (P. aeruginosa in burn wound infections. We aimed to explore the feasibility of using 3-oxo-C12-HSL-r-PcrV conjugate as a candidate vaccine against P. aeruginosa caused infections. 3-oxo-C12-HSL-r-PcrV conjugate was prepared and used for immunization of mice (10 μg, subcutaneous, three times, at 2-week intervals. Mice were divided into five groups: I: PcrV; II: 3-oxo-C12-HSL-r-PcrV (10 μg; III: 3-oxo-C12-HSL-r-PcrV (20 μg; IV: 3-oxo-C12-HSL; and V: PBS receiving groups.  After each shot of immunization, total and isotype antibody responses against corresponding antigen were measured to determine the immunization efficacy. One month after the last immunization, all groups were burned and challenged subeschar with P. aeruginosa PAO1. Survival rate and bacterial quantity in the skin and internal organs (liver and spleen were evaluated 25-hr after burn infection. Immunization with 3-oxo-C12-HSL-r-PcrV significantly increased total IgG and specific subclass antibodies (IgG1, IgG2a, IgG2b, and IgM in the serum of the groups II and III compared to the control group (p<0.001. While all the control mice (PBS injected group died within 2 days after bacterial challenge, 64% of the group I, 78% of group II, and 86% of group III, survived within 14 days after challenge. Interestingly, bacterial burden in the liver and spleen of 3-oxo-C12-HSL-r-PcrV injected group (III was significantly lower than the control group (p<0.001.  The present study proposed two-component vaccine to inhibit Pseudomonas infections in burned mouse. 

  18. Validity of death certificates for injury-related causes of death. (United States)

    Moyer, L A; Boyle, C A; Pollock, D A


    Exploration of the validity of death certificate information for classifying underlying causes of death has historically focused on "natural" or disease-related causes of death. Current interest in injury-related deaths has emphasized the need for proper certification and coding of these deaths. In this study, the authors compared agreement of the underlying cause of death as determined from death certificate information with that determined from an independent review of all relevant medical and legal documents of death by a panel of physicians. The study sample included all deaths (n = 446) occurring over an approximately 18-year follow-up period (1965-1983) in a randomly selected cohort of 18,313 US Army Veterans of the Vietnam era. Using the physician panel as the "gold standard," sensitivity and specificity were 90% or greater for broad groupings of motor vehicle crash deaths (International Classification of Diseases, Ninth Revision (ICD-9), codes E810-E825), suicides (codes E950-E959), and homicides (codes E960-E969). Agreement for deaths from unintentional poisonings (codes E850-E869), mostly drug- and alcohol-related, was poor (sensitivity, 50 percent); in general, the ICD-9 drug- and alcohol-specific nomenclature is difficult to apply. The specificity and sensitivity for the individual three-digit suicide and homicide codes were all greater than 90%, and although the specificity for three-digit motor vehicle crash deaths was also above 90%, the sensitivity was lower, from 29% to 83%. Agreement on the fourth digit of ICD-9--for example, the role of the decedent in a motor vehicle crash death--was generally poor. The lack of descriptive information on death certificates to allow detailed coding was chiefly responsible for the poor agreement.

  19. Basing the treatment of stereotypic and self-injurious behaviors on hypotheses of their causes. (United States)

    Repp, A C; Felce, D; Barton, L E


    Stereotypic and self-injurious behaviors are common forms of maladaptive responding demonstrated by severely handicapped persons. Various review papers suggest that no single treatment procedure is universally effective. Although there may be many reasons for this finding, one could be that people engage in these behaviors for various reasons, and that procedures that are incompatible with the cause of the behavior are unlikely to be effective. These studies also suggest many hypotheses for the development and maintenance of these behaviors, three of which are the self-stimulation, positive reinforcement, and negative reinforcement hypotheses. The purpose of this paper was to determine whether one of these hypotheses could be matched to the cause of the behavior and used as an effective treatment procedure. We therefore compared one hypothesis with one other for 3 subjects in a three-phase study. During baseline, data were taken in two classrooms for each subject, and a judgement was made about the hypothesis most likely to be related to the cause of the behavior. During the second phase, a treatment based on that hypothesis was used in one classroom, and a treatment based on another hypothesis was used in the second classroom. During the third phase, the treatment that was most effective in the second phase was used in both classrooms. Results showed that a successful treatment program can be developed on an hypothesis of why the behavior occurred during baseline. Results are discussed in terms of supporting the argument that treatment programs should be based on a functional analysis of the behavior in its environmental context.

    Background Environmental toxins can destroy the physiological process of spermatogenesis and even lead to male infertility.Resveratrol(RES)is a natural phytoalexin with a wide range of biological activities.Some recent researches have demonstrated that RES can increase sperm output and protect sperm from apoptosis caused by physical damage.However,there is no evidence indicating that it can also exhibit a similar activity in testis injury caused by environmental toxins.This study was designed to evaluate the protective effect of resveratrol on testis damaged by environmental toxins and to elucidate the possible mechanism of its protective effect.Methods In this study 2,5-hexanedione(2,5-HD)was used as the injury agent.Forty male SD rats were randomly divided into 5 groups.During the first 5 weeks,group A was raised normally,groups B,C,D and E were exposed to 1% 2,5-HD;during the following 9 weeks,group C,D,E received intragastric administration of different concentrations of carboxymethylcellulose.Physical signs,body weight gain and testis weight were comparatively obsewed.Numbers and diameters of seminiferous tubules were analyzed following HE staining.In addition,expression of the c-kit protein and gene in spermatogenic cells jn every group was detected with immunohistochemistry,Western blot or RT-PCR.Results The 2,5-HD treatment resulted in physical signs that became worse and in emarciated testis.HE staining and immunohistochemistry showed that seminiferous tubules became emarcid,obsolete spermatogonia being stagnant and expression of c-kit protein being depressed.After oral administration of resveratrol,the 2,5-HD.induced physical signs were improved and close to the normal rats.The gain of body weight increased(P<0.01).The recovery of testis weight was significant(P<0.01).At the histological level,the seminiferous epithelia began to differentiate(P<0.01):and even the physiological process of spermatogenesis restarted.Moreover,expression of c-kit protein

  3. 烧伤高代谢机制的再认识及调控策略%Further understanding of the hypermetabolism mechanism in burn injury and the strategy of regulation and control

    Institute of Scientific and Technical Information of China (English)



    The pattern of metabolism changes obviously after severe burn trauma,and it is characterized by an immensely increase in energy consumption,persistent strengthening in catabolism,and impediment of utilization of nutrient substrate.It will lead to autophagy,continuous consumption,and progressive emaciation,etc.If these pathological phenomena can not be effectively corrected,the prognosis of patients with serious burn will be poor,with complications of organ damage,immune dysfunction,and delayed wound healing,etc.Hypermetabolism after burn has become one of the leading causes of multiple organ dysfunction and even death.After many years' research,we have a certain understanding of burn hypermetabolism,but it is still difficult to clearly explain the mechanism up to now.Moreover,the measures of regulating hypermetabolism are still not perfect,hampering the advance of treatment of serious burn trauma.The purpose of the article is to analyze and discuss the essential mechanism of hypermetabolism after burn,basing on the new literature and a series of our experimental and clinical studies.Meanwhile the regulation strategy concerning burn hypermetabolism is proposed.It focuses on regulation of endocrine and inflammatory mediators,as well as maintenance of gastrointestinal structure and function.

    Hashemi, Sayed Saeed; Sharhani, Asaad; Lotfi, Bahare; Ahmadi-Juibari, Toraj; Shaahmadi, Zahra; Aghaei, Abbas


    Burn is the most common pediatric injuries all over the world. The aim of this study was to study the epidemiology of burn in under 15-year-old Iranian children by applying a systematic review. The related articles published before 2016 have been gathered from international databases by using the keywords in term of pediatric burns such as ScienceDirect, PubMed, Iranmedex, Google Scholar, Embase, Magiran, and SID. The checklists of STROBE have been applied to evaluate the quality of the reviewed data. A total of 35 relevant studies were extracted and evaluated. In most studies, the incidence of pediatric burns in male patients was more than female patients by 9.5 to 50 cases in 100,000 per children. Mortality rate of pediatric burn was between 1.7 and 18.5%. The most common cause of pediatric burn was hot water or other hot liquids. Pediatric burn in urban areas was higher and the highest number of pediatric burns occurred at home. Burn is considered as one of the major incidents related to children's health that required planning to reduce its incidence, especially in the lower age groups as well as male patients who are more active and susceptible to burn.
