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

Full Text Available Background: The burn wound represents a susceptible site for opportunistic colonization by organisms of endogenous and exogenous origin. The present study was undertaken to analyze the microflora of burn wounds of the burn patients from a tertiary care hospital in Kashmir, India. Materials sand Methods: The study included all patients with acute burns admitted from January 2010 to December 2011 (2 years. The standard techniques, as practiced during collection of microbiological specimens, were used during wound swab/biopsy collection. Results: 74.19% of swab cultures yielded single isolates. On swab culture, Pseudomonas aeruginosa was the commonly isolated organism (46.86%. Staphylococcus aureus was the most common isolate isolated during 1st postburn week (30.86%. 258/288 (89.58% blood cultures were sterile. 8/58 (13.79% blood cultures were positive during the second postburn week. S. aureus was the most common organism grown on blood culture (44.44%. P. aeruginosa was mostly sensitive to polymyxin B (86.0%, amikacin (40.0%, and ciprofloxacin (37.3%, respectively. S. aureus was most commonly sensitive to linezolid (85.0% and vancomycin (78.8%% whereas Acinetobacter spp. was sensitive to polymyxin B (65.3%, piperacillin/tazobactam (44.9%, and amikacin (38.8%. Patients (27.27% who showed local signs of burn wound infection and positive blood culture were subjected to burn wound biopsy. 93.33% of patients who had counts >105 colony-forming unit/g of tissue showed significant association with local signs of burn wound infection and positive blood culture for any organism. Conclusion: The microbiological surveillance of burn wounds needs to be continued for a rational antibiotic policy and prevention of emergence of resistant organisms. Burn wound biopsy culture is an effective tool for quantitative analysis of burn wounds; however, subjecting this biopsy to histological examination is more predictable of burn wound infection and its correlation

Wound closure represents a primary goal in the treatment of very deep and/or large wounds, for which the mortality rate is particularly high. However, the spontaneous healing of adult skin eventually results in the formation of epithelialized scar and scar contracture (repair), which might distort the tissues and cause lifelong deformities and disabilities. This clinical evidence suggests that wound closure attained by means of skin regeneration, instead of repair, should be the true goal of burn wound management. The traditional concept of temporary wound dressings, able to stimulate skin healing by repair, is thus being increasingly replaced by the idea of temporary scaffolds, or regenerative templates, able to promote healing by regeneration. As wound dressings, polymeric hydrogels provide an ideal moisture environment for healing while protecting the wound, with the additional advantage of being comfortable to the patient, due to their cooling effect and non-adhesiveness to the wound tissue. More importantly, recent advances in regenerative medicine demonstrate that bioactive hydrogels can be properly designed to induce at least partial skin regeneration in vivo. The aim of this review is to provide a concise insight on the key properties of hydrogels for skin healing and regeneration, particularly highlighting the emerging role of hydrogels as next generation skin substitutes for the treatment of full-thickness burns.

Full Text Available Skin covers the entire body. It is the most important protective organ. Since the burn injury is most painful of all injuries, dressings play an important part of the management. Dressing of the burn wound is very essential to provide pain relief, to promote early healing, to prevent contractures, and to help early mobilization. Many workers from time immemorial have used different types of dressings so as to provide desired results. I use sterile polyethylene drape as a dressing material after covering it with the first layer of gauze soaked in silver sulfadiazine cream. The results are encouraging as there is near total absence of pain experienced by patients and removal is totally pain-free without any bleeding. There is no need for escharotomies, and there is early removal of the slough with no contracture. The polyethylene drapes are easily available in the market, easy to store, available sterile, and totally cost-effective. They help reduce the hospital stay of the patient. The need of anesthesia for surgeries such as escharotomies and debridement is significantly reduced.
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.

Early management in burns, i.e. prior to admission in a burn center, is essential for an optimal process and outcome of burn care. Several publications have reported suboptimal early management, including low levels of pain medication after trauma, especially in children. The aim of this study was to evaluate the current practice in the Netherlands and factors related to early management in pediatric burns, i.e. cooling, wound covering and pain management. To study possible change and improvement over time, two study periods were compared. This study involved two periods; January 2002-March 2004 (period 1) and January 2007-August 2008 (period 2). All children (0-15 years of age) with acute burns admitted within 24h after burn to one of the three Dutch Burn centers with a formal referral were eligible. Data were obtained from patient records, both retrospectively and prospectively. A total of 323 and 299 children were included in periods 1 and 2, respectively. The vast majority of children in both study periods had been cooled before admission (>90%). Over time, wound covering increased significantly (from 64% to 89%) as well as pain treatment (from 68% to 79%). Predominantly paracetamol and morphine were used. Referral from ambulance services (OR=41.4, 95%CI=16.6-103.0) or general practitioners (OR=59.7, 95%CI=25.1-141.8) were strong independent predictors for not receiving pre-burn center pain medication. On the other hand, flame burns (OR=0.2, 95%CI=0.1-0.5) and more extensive burns (TBSA 5-10%: OR=0.4, 95%CI=-0.2 to 0.8; TBSA≥10%: OR=0.2, 95%CI=0.1-0.4) were independent predictors of receiving pain medication. Referring physicians of children with burns were overall well informed: they cool the wound after burns and cover it before transport to prevent hypothermia and reduce the pain. Additional studies should be conducted to clarify the duration and temperature for cooling to be effective. Furthermore, there is room and a need for improvement regarding early

Full Text Available Background and Objectives: Wound care in burn patients is associated with severe anxiety that is characterized by feeling of fear and prediction of burn dressing pain. The purpose of this study was to determine the correlation between pain and pain anxiety in burn patients. Methods: In this descriptive-analytical study, 60 eligible patients hospitalized in men’s and women’s burn wards of Mashhad Imam Reza Hospital, were selected using available sampling. Pain anxiety and pain severity were measured using self-report pain anxiety questionnaire and visual analog scale, respectively, before and after burn dressing during three weeks (once a week. Data were analyzed by descriptive statistics and Pearson correlation test. Results: In this study, there was a significant linear correlation between pain and pain anxiety in the first week (r=0.512, p<0.001, but there was no significant linear correlation between these variables in the second (r=0.079, p=0.547 and third (r=0.167, p=0.203 weeks. Conclusion: According to the results of this study, assessment and treatment of pain anxiety are essential elements of pain care and management in burn patients.

Burn wound care procedures are very painful and lead to distress. Live music therapy has shown beneficial effects on distress and pain in specific pediatric patient populations. In this study we measured whether live music therapy has beneficial effects in terms of less distress and pain in children with burns after wound care procedures. This randomized assessor-blinded controlled trial (RCT) took place at the burns unit of the Red Cross War Memorial Children's Hospital, Cape Town, South Africa. It included newly admitted inpatients between the ages of 0 and 13 years undergoing their first or second wound care procedures. Excluded were children with a hearing impairment or low level of consciousness. The intervention group received one live music therapy session directly after wound care in addition to standard care. The control group received standard care only. The primary outcome was distress measured with the Observational Scale of Behavioral Distress-revised (OSBD-r). The secondary outcome was pain measured with the COMFORT-behavioral scale (COMFORT-B). In addition, in children older than 5 years self-reported distress with the validated Wong-Baker scale (FACES) and pain with the Faces Pain Scale-Revised (FPS-R) were measured. Patients in both groups were videotaped for three minutes before wound care; during the music therapy or the control condition; and for two minutes thereafter. Two researchers, blinded to the study condition, independently scored the OSBD-r and the COMFORT-B from the video footage before and after music therapy. We included 135 patients, median age 22.6 months (IQR 15.4-40.7 months). Change scores did not significantly differ between the intervention and the control groups for either distress (p=0.53; d=0.11; 95% CI -0.23 to 0.45) or pain (p=0.99; d=0.04; 95% CI -0.30 to 0.38). Self-reported distress in a small group of children (n=18) older than 5 years indicated a significant reduction in distress after live music therapy (p=0

The evaluation and treatment of head and neck burns remains a challenge to the burn surgeon, because of the long-term emotional and psychologic effects of even the most minor change in facial appearance. Fortunately, the results currently achieved are orders of magnitude better than previously available, but they still remain far below the perfect outcome desired by both the physician and the burn victim.

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.

To describe the management of pain prevention associated with burn care. Multi-centre, observational, cross-sectional, descriptive study performed in 4 burn units in Spain. A total of 55 patients undergoing 64 procedures were analysed. Burns were classified as severe (90.4%), third-degree (78.2%) and caused by thermal agents (81.8%). Background analgesia consisted of non-opioid drugs (87.5%) and opioids (54.7%) [morphine (20.3%), morphine and fentanyl (14.1%) or fentanyl monotherapy (15.6%)]. Burn care was performed by experienced nurses (96.9%); 36.5% followed guidelines. The mean duration of procedures was 44 minutes (Statistical Deviation, SD: 20.2) and the mean duration of pain was 27 minutes (SD: 44.6). Procedural pain was primarily managed with opioid analgesics: fentanyl monotherapy and in combination (84%) and fentanyl monotherapy (48%) administered sublingually (89.1%). Patients described pain as different to usual baseline pain (97%), with a mean maximum intensity score of 4.2 points (SD: 3.3) on the VAS scale and a 34% increase in the intensity of pain. The mean patient and healthcare professional satisfaction score per procedure was 6/10 (SD: 1.9) and 5.5/10 (SD: 1.7), respectively. The results of the study describe the management of pain associated with burn care in clinical practice, helping optimise pain control.

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

Full Text Available Abstract Background The intense pain and anxiety triggered by burns and their associated wound care procedures are well established in the literature. Non-pharmacological intervention is a critical component of total pain management protocols and is used as an adjunct to pharmacological analgesia. An example is virtual reality, which has been used effectively to dampen pain intensity and unpleasantness. Possible links or causal relationships between pain/anxiety/stress and burn wound healing have previously not been investigated. The purpose of this study is to investigate these relationships, specifically by determining if a newly developed multi-modal procedural preparation and distraction device (Ditto™ used during acute burn wound care procedures will reduce the pain and anxiety of a child and increase the rate of re-epithelialization. Methods/design Children (4 to 12 years with acute burn injuries presenting for their first dressing change will be randomly assigned to either the (1 Control group (standard distraction or (2 Ditto™ intervention group (receiving Ditto™, procedural preparation and Ditto™ distraction. It is intended that a minimum of 29 participants will be recruited for each treatment group. Repeated measures of pain intensity, anxiety, stress and healing will be taken at every dressing change until complete wound re-epithelialization. Further data collection will aid in determining patient satisfaction and cost effectiveness of the Ditto™ intervention, as well as its effect on speed of wound re-epithelialization. Discussion Results of this study will provide data on whether the disease process can be altered by reducing stress, pain and anxiety in the context of acute burn wounds.

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

Full Text Available Introduction: Burn wound infections are important cause of mortality, morbidity and prolonged hospitalization in burn patients as the causative agent is generally a multidrug resistant organism. The pattern of microbial flora infecting burn wound varies according to geographical pattern as well as with duration of hospital stay. Objective: The present study aims to identify the causative agents of burn wound infections in our hospital, to assess the change in pattern of flora in accordance to duration of wound as well as to determine the sensitivity pattern of isolates. Materials and Methods: Wound swabs from 52 patients admitted in Burn unit of IMS and SUM Hospital, Bhubaneswar were collected every 5th day during their hospital stays and were cultured. The results were interpreted according to the standard methods and antibiotic susceptibility pattern was noted. Results: The most common organism isolated was Staphylococcus aureus, that is, 20 (47.6% while Klebsiella spp. 12 (28.6% was the most common Gram-negative isolate. The commonest organism isolated in the 1st week of hospital stay was S. aureus (15.4%, but it was Acinetobacter spp. (22.2% in 2nd week and coagulase negative Staphylococcus in 3rd week of hospital stay S. aureus was mostly sensitive to levofloxacin (77.8% and netilmycin (98%. Conclusion: The pattern of bacterial flora changes according to duration of hospital stay. Effective strict isolation techniques and infection control are thus needed to decrease the occurrence of burn wound infection.

As we have emphasized, the diagnosis of burn wound infections in the high-risk burned child can be difficult and depends on a very high degree of suspicion and daily clinical evaluation of the burn wound site by consistent observers. Appropriate precautions include meticulous hand-washing and the use of gloves when handling the wound site and prophylactic application of a topical antibacterial agent such as SSD cream. Wound therapy should include routine vigorous surgical débridement. Surveillance wound cultures should be done weekly to determine the emergency of colonization and aid in the selection of empiric antimicrobial regimens when these are appropriate. Wound biopsy for histological examination and quantitative culture is highly recommended in the severely ill child with an unclear etiology or site of infection. If, despite these measures, sepsis ensues, then systemic antibiotics must be started empirically as an adjuctive therapy to surgical débridement. Knowledge of the organisms colonizing a wound will prove useful in choosing an antibiotic regimen while awaiting definitive results of blood and wound biopsy cultures. Without this information, early burn sepsis therapy should focus on gram-positive organisms, while infection later in the course should raise suspicion of nosocomial pathogens such as P. aeruginosa, other enteric bacilli, and C. albicans. An initial regimen might include nafcillin plus ceftazidime or an aminoglycoside, with anaerobic coverage depending on considerations noted previously. Once the causative agent is identified, therapy must be modified accordingly. Amphotericin B and acyclovir use should be guided by positive cultures from the burn wound site along with systemic evidence of dissemination. Available studies do not yet make clear the role of empiric immunotherapy with intravenous gamma globulin in the burned child. Therefore, its use cannot be recommended at the present time, although the development of specific

The aim of this study was to evaluate the effect of silk sericin, a protein from silkworm cocoon, on scratch wound healing in vitro. For applicable result in clinical use, we also study the efficacy of sericin added to a standard antimicrobial cream, silver zinc sulfadiazine, for open wound care in the treatment of second-degree burn wounds. In vitro scratch assays show that sericin at concentration 100 μg/mL can promote the migration of fibroblast L929 cells similar to epidermal growth factor (positive control) at 100 μg/mL. After 1 day of treatment, the length of scratch in wounds treated with sericin was significantly shorter than the length of negative control wounds (culture medium without sericin). For clinical study, a total of 29 patients with 65 burn wounds which covered no less than 15 % of total body surface area were randomly assigned to either control (wounds treated with silver zinc sulfadiazine cream) or treatment (wounds treated with silver zinc sulfadiazine with added sericin cream) group in this randomized, double-blind, standard-controlled study. The results showed that the average time to reach 70 % re-epithelialization of the burned surface and complete healing in the treatment group was significantly shorter, approximately 5-7 days, than in the control group. Regarding time for complete healing, control wounds took approximately 29.28 ± 9.27 days, while wounds treated with silver zinc sulfadiazine with added sericin cream took approximately 22.42 ± 6.33 days, (p = 0.001). No infection or severe reaction was found in any wounds. This is the first clinical study to show that silk sericin is safe and beneficial for burn wound treatment when it is added to silver sulfadiazine cream.

Care of equine wounds in the field can be a challenging endeavor. Many times, wound care is complicated by chronicity or by prior inappropriate care in addition to the great degree of tissue trauma that occurred when the horse was wounded. Recognizing involvement of synovial structures, loss of skin, and damage to bone are critical in the initial examination of wounds and will guide future care. Education of clients is also important in that preparing them for possible outcomes during healing may help improve compliance and proper treatment of wound. Owners and trainers often perform much of the daily care and monitoring of equine wounds and thus can greatly assist or impede the progress. Bandaging is important to management of equine wounds-especially on the limbs-and is sometimes overlooked because of its labor-intensive nature and the desire for a spray, ointment, or salve that will heal the wound. The practitioner that improves and utilizes his or her understanding of the wound-healing process in concert with his or her knowledge of local anatomy will be the one who is best equipped to care for wounds in ambulatory practice.

In the last years, health care professionals faced with an increasing number of patients suffering from wounds and burns difficult to treat and heal. During the wound healing process, the dressing protects the injury and contributes to the recovery of dermal and epidermal tissues. Because their biocompatibility, biodegradability and similarity to macromolecules recognized by the human body, some natural polymers such as polysaccharides (alginates, chitin, chitosan, heparin, chondroitin), proteoglycans and proteins (collagen, gelatin, fibrin, keratin, silk fibroin, eggshell membrane) are extensively used in wounds and burns management. Obtained by electrospinning technique, some synthetic polymers like biomimetic extracellular matrix micro/nanoscale fibers based on polyglycolic acid, polylactic acid, polyacrylic acid, poly-ɛ-caprolactone, polyvinylpyrrolidone, polyvinyl alcohol, polyethylene glycol, exhibit in vivo and in vitro wound healing properties and enhance re-epithelialization. They provide an optimal microenvironment for cell proliferation, migration and differentiation, due to their biocompatibility, biodegradability, peculiar structure and good mechanical properties. Thus, synthetic polymers are used also in regenerative medicine for cartilage, bone, vascular, nerve and ligament repair and restoration. Biocompatible with fibroblasts and keratinocytes, tissue engineered skin is indicated for regeneration and remodeling of human epidermis and wound healing improving the treatment of severe skin defects or partial-thickness burn injuries.

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

Burn wound infections carry considerable mortality and morbidity amongst burn injury victims who have been successfully rescued through the initial resuscitation. This study assessed the prevalent microrganisms causing burn wound infections among hospitalized patients; their susceptibility pattern to commonly used antibiotics; and the frequency of infections with respect to the duration of the burn wounds. This study was carried out at Burn Care Centre, Pakistan Institute of Medical Sciences (PIMS), Islamabad, Pakistan over a period of two years (i.e. from June 2010 to May 2012). The study included all wound-culture-positive patients of either gender and all ages, who had sustained deep burns and underwent definitive management with wound excisions and skin auto-grafting. Patients with negative cultures of the wounds were excluded. Tissue specimens for culture and sensitivity were collected from burn wounds using standard collection techniques and analyzed at microbiological laboratory. Out of a total of 95 positive microbial growths, 36 were Pseudomonas aeruginosa (35.29%) as the most frequent isolate found, followed by 21 Klebsiella pneumoniae (20.58%), 19 Staphylococcus aureaus (18.62%), 10 Proteus (9.80%), 7 E. coli (6.86%), 7 Acinetobacter (6.86%), and 4 Candida (3.92%). A variable antibiotic susceptibility pattern was observed among the grown microbes. Positive cultures were significantly more frequent among patients with over two weeks duration of burn wounds. P. aeruginosa, K. pneumoniae and S. aureus constituted the most common bacterial microbes of burn wounds in our in-patients cases. Positive cultures were more frequent among patients with over two weeks duration of burn wounds. Early excision and skin grafting of deep burns and adherence to infection control measures can help to effectively reduce the burden of these infections.

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

Burns are frequently encountered on the modern battlefield, with 5% - 20% of combat casualties expected to sustain some burn injury. Addressing immediate life-threatening conditions in accordance with the MARCH protocol (massive hemorrhage, airway, respirations, circulation, hypothermia/head injury) remains the top priority for burn casualties. Stopping the burning process, total burn surface area (TBSA) calculation, fluid resuscitation, covering the wounds, and hypothermia management are the next steps. If transport to definitive care is delayed and the prolonged field care stage is entered, the provider must be prepared to provide for the complex resuscitation and wound care needs of a critically ill burn casualty. 2015.

Telemedical wound care is one of the applications of teledermatology. We present our experience using telemedicine in the successful assessment and treatment of three patients with hard-to-heal ulcers. Three patients were seen at the PEMEX General Hospital in Veracruz, Mexico. The first patient was a 53-year-old man with hypertension, morbid obesity, chronic venous insufficiency, recurrent erysipelas, leg ulcers and lymphoedema. There was one ulcer on his left lower leg (20 x 10 cm) and one on his right leg (9 x 7 cm). The second patient was a 73-year-old woman with class III obesity and ulcers in her right leg, secondary to surgical debridement of bullous erysipelas. The third patient was a 51-year-old female with rheumatoid arthritis with one ulcer on each leg and chronic lymphostasis. Photographs with a digital camera were taken and sent weekly via email to a wound care specialist in Mexico City. The photographs allowed the expert to diagnose and evaluate the chronic wounds periodically. In the present cases, telemedicine allowed us to have a rapid evaluation, diagnosis and treatment. The images were of enough quality to be useful and small enough to be sent via regular email to the remote physician who immediately gave his feedback. The expert was confident to give therapeutic recommendations in this way, and we considered this method to be very cost-effective, saving the patient and the health care system, especially in transportation.

The study was undertaken to evaluate the burn wound healing property of oil of Cocos nucifera and to compare the effect of the combination of oil of Cocos nucifera and silver sulphadiazine with silver sulphadiazine alone. Partial thickness burn wounds were inflicted upon four groups of six rats each. Group I was assigned as control, Group II received the standard silver sulphadiazine. Group III was given pure oil of Cocos nucifera , and Group IV received the combination of the oil and the standard. The parameters observed were epithelialization period and percentage of wound contraction. It was noted that there was significant improvement in burn wound contraction in the group treated with the combination of Cocos nucifera and silver sulphadiazine. The period of epithelialization also decreased significantly in groups III and IV. It is concluded that oil of Cocos nucifera is an effective burn wound healing agent.

Abstract: Hypergranulation tissue (or also known as overgranulation may negatively influence burn wound healing time and contribute to recurrence of contractures in burn wounds and grafts. Subsequently, the treatment of hypergranulation tissue remains controversial and problematic. In this case series, we aimed to examine the feasibility and document the use of topical hydrocortisone in the treatment of hypergranulation tissue formation resulting from burn wounds. We report five cases where hypergranulation tissue developed following deep dermal/full-thickness burns. Initial burn wound treatment included necrotic tissue debridement, wound cleansing, and Flaminal®. All five cases underwent surgical debridement and split-skin grafting. Upon identification of hypergranulation tissue, hydrocortisone acetate 0.25% was applied topically as usual care for the treatment of hypergranulation tissue. All five patients had deep dermal/full-thickness burns with a total body surface area ranging from 22% to 61% and were aged from 3–41 years. All five cases developed hypergranulation tissue during their admission after debridement and split-thickness skin grafts. All patients showed an improvement in the treated areas with a complete regression of hypergranulation tissue and closure of the burn wounds. No clinically apparent local or systemic side effects of the treatment were observed. Topical hydrocortisone can be utilized as an effective, inexpensive, and noninvasive practical option in the treatment of hypergranulation tissue resulting from burn wounds

The early diagnosis of infection or sepsis in burns are important for patient care. Globally, a large number of burn centres advocate quantitative cultures of wound biopsies for patient management, since there is assumed to be a direct link between the bioburden of a burn wound and the risk of microbial invasion. Given the conflicting study findings in this area, a systematic review was warranted. Bibliographic databases were searched with no language restrictions to August 2015. Study selection, data extraction and risk of bias assessment were performed in duplicate using pre-defined criteria. Substantial heterogeneity precluded quantitative synthesis, and findings were described narratively, sub-grouped by clinical question. Twenty six laboratory and/or clinical studies were included. Substantial heterogeneity hampered comparisons across studies and interpretation of findings. Limited evidence suggests that (i) more than one quantitative microbiology sample is required to obtain reliable estimates of bacterial load; (ii) biopsies are more sensitive than swabs in diagnosing or predicting sepsis; (iii) high bacterial loads may predict worse clinical outcomes, and (iv) both quantitative and semi-quantitative culture reports need to be interpreted with caution and in the context of other clinical risk factors. The evidence base for the utility and reliability of quantitative microbiology for diagnosing or predicting clinical outcomes in burns patients is limited and often poorly reported. Consequently future research is warranted. Crown Copyright © 2017. Published by Elsevier Ltd. All rights reserved.

Aloe vera and Vitis vinifera have been traditionally used as wound healing agents. The present study aimed to investigate the effects of aloe emodin and resveratrol in the burn wound healing procedure. Burn wounds are common in developed and developing countries, however, in developing countries, the incidence of severe complications is higher and financial resources are limited. The results of the present study demonstrated that neither aloe emodin or resveratrol were cytotoxic to THP-1 macrophages at concentrations of 1, 100 and 500 ng/ml. A significant increase in wound-healing activity was observed in mice treated with the aloe emodin and resveratrol, compared with those which received control treatments. The levels of IL-1β in the exudates of the burn wound area of the treated mice increased in a time-dependent manner over 7 days following burn wound injury. At 10 days post-injury, steady and progressive wound healing was observed in the control animals. The present study confirmed that increased wound healing occurs following treatment with aloe emodin,, compared with resveratrol, providing support for the use of Aloe vera plants to improve burn wound healing.

Summary In order to summarize the progress of burn wound management of the patients in our burn ward and its correlation with the improvement of treatment results in the past 44 years, the general data (hospitalization time, cure rate, operation times) of 12,568 cases were analysed in terms of three periods, namely 1958 to 1980, 1981 to 1990, and 1991 to 2002. The bene?cial effects of the systemic application of recombinant human growth hormone, post-burn immediate escharectomy en masse, the external application of epithelial growth factor, and the coverage of split-thickness skin donor sites with razor-thick skin on wound healing and overall therapeutic results were also analysed. It was found that there was an increase in the number of burn patients admitted to our burn ward in recent decades. The overall cure rate, especially that of major burn patients, increased signi?cantly with the improvement of burn wound management. Hospitalization time was shortened and wound-healing time reduced. The analysis suggested that escharectomy en masse as early as possible, systemic application of growth hormone, and external application of epithelial growth factor are bene?cial to early burn wound healing.

Full Text Available PURPOSE: To investigate if the methanolic extract of the Otostegia persica can accelerating healing process of burn wound because of its anti-inflammatory and antioxidant effects. METHODS:Forty eight male Wistar rats were randomized into three study groups of 16 rats each. Burn wounds were created on dorsal part of shaved rats using a metal rod. In group I the burn wound was left without any treatment. Group was treated with topical silver sulfadiazine pomade. In group III, ointment containing the OP extract was administered. Skin biopsies were harvested from burn area on the 3rd, 5th, 14th and 21st days after burn and examined histologically. RESULTS: Re-epithelialization in the control group and in group II was lower than in group III. Re-epithelialization in groups II and III was significantly different from that in the control group. On the 5th day of the experiment, we assessed lower inflammation in the burn area compared to control group. This means that the inflammation was suppressed by methanolic extract of OP. From day 5 to 14; the fibroblast proliferation peaked and was associated with increased collagen accumulation. It was obvious that angiogenesis improved more in the groups II and III, which facilitated re-epithelialisation. CONCLUSION:Methanolic extract of Otostegia persica exhibited significant healing activity when topically applied on rats. OP is an effective treatment for saving the burn site.

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

Full Text Available Haitao Ren,1 Yuan Li21Department of Burns and Wound Center, the Second Affiliated Hospital, School of Medicine, Zhejiang University, Hangzhou, People's Republic of China; 2Department of Ultrasound, Women's Hospital, School of Medicine, Zhejiang University, Hangzhou, People's Republic of ChinaAbstract: We present two typical cases of severe complications (sepsis and hemorrhage after negative pressure wound therapy (NPWT in burned patients. Necrotic tissues in some deep burn wounds are difficult to judge correctly and remove thoroughly. An electrically burned blood vessel looks “intact” but can easily break. Necrotic tissue or injured blood vessels when using NPWT are dangerous, both for causing sepsis and hemorrhage. This is the first article that reports the severe complications of NPWT in burned patients. It is imperative to heed indications and avoid contraindications. Proper preparation of wound beds, close observation, and sufficient irrigation are also crucial to avoid these severe complications, and there is an urgent need to substitute the central vacuum system with the low-pressure system.Keywords: negative pressure wound therapy, complication, burn sepsis, bleeding, drainage

Since its discovery approximately 200 years ago, chitosan, as a cationic natural polymer, has been widely used as a topical dressing in wound management owing to its hemostatic, stimulation of healing, antimicrobial, nontoxic, biocompatible and biodegradable properties. This article covers the antimicrobial and wound-healing effects of chitosan, as well as its derivatives and complexes, and its use as a vehicle to deliver biopharmaceuticals, antimicrobials and growth factors into tissue. Studies covering applications of chitosan in wounds and burns can be classified into in vitro, animal and clinical studies. Chitosan preparations are classified into native chitosan, chitosan formulations, complexes and derivatives with other substances. Chitosan can be used to prevent or treat wound and burn infections not only because of its intrinsic antimicrobial properties, but also by virtue of its ability to deliver extrinsic antimicrobial agents to wounds and burns. It can also be used as a slow-release drug-delivery vehicle for growth factors to improve wound healing. The large number of publications in this area suggests that chitosan will continue to be an important agent in the management of wounds and burns. PMID:21810057

Erythropoietin interacts with vascular endothelial growth factor (VEGF) and stimulates endothelial cell mitosis and motility; thus it may be of importance in the complex phenomenon of wound healing. The purpose of this study was to investigate the effect of recombinant human erythropoietin (rHuEPO) on experimental burn wounds. Randomized experiment. Research laboratory. C57BL/6 male mice weighing 25-30 g. Mice were immersed in 80 degrees C water for 10 secs to achieve a deep-dermal second degree burn. Animals were randomized to receive either rHuEPO (400 units/kg/day for 14 days in 100 microL subcutaneously) or its vehicle alone (100 microl/day distilled water for 14 days subcutaneously). On day 14 the animals were killed. Burn areas were used for histologic examination, evaluation of neoangiogenesis by immunohistochemistry, and expression (Western blot) of the specific endothelial marker CD31 as well as quantification of microvessel density, measurement of VEGF wound content (enzyme-linked immunosorbent assay), expression (Western blot) of endothelial and inducible nitric oxide synthases, and determination of wound nitric oxide (NO) products. rHuEPO increased burn wound reepithelialization and reduced the time to final wound closure. These effects were completely abated by a passive immunization with specific antibodies against erythropoietin. rHuEPO improved healing of burn wound through increased epithelial proliferation, maturation of the extracellular matrix, and angiogenesis. The hematopoietic factor augmented neoangiogenesis as suggested by the marked increase in microvessel density and by the robust expression of the specific endothelial marker CD31. Furthermore, rHuEPO enhanced the wound content of VEGF caused a marked expression of endothelial and inducible nitric oxide synthases and increased wound content of nitric oxide products. Our study suggests that rHuEPO may be an effective therapeutic approach to improve clinical outcomes after thermal injury.

Concentration and properties of free radicals in the burn wounds treated with propolis were examined by the use of electron paramagnetic resonance spectroscopy. Magnetic spin-spin interactions and complex free radicals structures in wound beds were studied. The results were compared to those obtained for silver sulphadiazine used as a standard pharmaceutical agent. The changes of free radicals in the matrix of injury with time of exposition on these substances were tested. The aim of this study was to check the hypothesis about the best influence of propolis on the burn wounds healing. It was confirmed that a relatively lower concentration of free radicals exists in the burn wounds treated with propolis. The homogeneously broadened spectra and a complex free radical system characterize the tested tissue samples. The fastening of spin-lattice relaxation processes in the matrix of injury after treatment with propolis and silver sulphadiazine was observed. Practical usefulness of electron paramagnetic resonance spectroscopy in alternative medicine was proved. PMID:23762125

The rate of wound healing and its effect on mortality has not been well described. The objective of this article is to report wound healing trajectories in burn patients and analyze their effects on in-hospital mortality. The authors used software (WoundFlow) to depict burn wounds, surgical results, and healing progression at multiple time points throughout admission. Data for all patients admitted to the intensive care unit with ≥ 20% TBSA burned were collected retrospectively. The open wound size (OWS), which includes both unhealed burns and unhealed donor sites, was measured. We calculated the rate of wound closure (healing rate), which we defined as the change in OWS/time. We also determined the time delay (DAYS) from day of burn until day on which there was a reduction in OWS healing (H), and 13 did not (NH). H differed from NH on age (38 years [32-57] vs 63 [51-74]), body mass index (27 [21-28] vs 32 [19-52]), 24-hour fluid resuscitation (12 L [10-16] vs 18 [15-20]), pressors during first 48 hours (72% vs 100%), use of renal replacement therapy (32% vs 92%), and mortality (4% vs 100%). Repeated measures analysis of covariance showed a significant difference between survivors and nonsurvivors on OWS as a function of time (Phealing rate (+2%/day) after postburn day 20 had 100% survival whereas those with a negative healing rate (-2%/day) had 100% mortality. For H patients, median DAYS was 41 (28-54); median DAYS/TBSA was 1.3 (1.0-1.9). Survivors had a 0.62% drop in OWS/day, or 4.3%/week. In this cohort of patients with ≥ 20% TBSA, there was a difference in mortality after postburn day 20, between patients with a positive healing rate (+2%/day, 100% survival) and those with a negative healing rate (-2%/day, 100% mortality, P < .05).

Abstract Background: Burns are common event and associated with a high incidence of death, disability, and high costs. Centella asiatica (L.) is a medicinal herb, commonly growing in humid areas in several tropical countries that improve wound healing. On the basis of previous studies, we compared the efficacy of Centiderm versus silver sulfadiazine (SSD) in partial thickness burning patients. Methods: Study population comprised burn victims referred to Velayat Burning Hospital at Rasht, Iran. The intervention group received Centiderm and control group SSD cream. Burn wounds were treated once daily at home. All of the wounds were evaluated till complete healing occurred and at the admission, days 3, 7, 14 objective signs; visual acuity score (VAS) and subjective signs were recorded. Re-epithelialization time and complete healing days were recorded. We used random fixed block for randomization. The randomization sequence was created using the computer. Patients and burning specialist physician were blinded. Results: Seventy-five patients randomized into 2 groups; (40 patients: Centiderm group; 35 patients: SSD group). The mean age of them was 30.67 ± 9.91 years and 19 of them were male (31.7%). Thirty patients in Centiderm and 30 patients in SSD group were analyzed. All of objective and subjective signs and mean of re-epithelialization and complete healing were significantly better in Centiderm group rather than SSD group (P < 0.05). There was no infection in Centiderm group. Conclusions: We showed that use of Centiderm ointment not only improved the objective and subjective signs in less than 3 days, but also the re-epithelialization and complete healing rather than SSD without any infection in the subjects.

Enzymatic wound debridement as an alternative to surgical debridement has been assessed for its effectiveness, safety and patient compliance. Aims: To assess the effectiveness and safety of papaya pulp as an enzymatic wound debriding agent in burns. Setting and Design: The study was conducted including 50 patients with second degree and third degree burns, age ranging from 15 to 60 years from January 2004 to December 2004 at the Burns Centre, Department of Plastic, Reconstructive and Burns Surgery, Jubilee Mission Medical College and Research Institute, Thrissur, Kerala, India. Materials and Methods: A prospective study including 50 patients with second degree and third degree burns, age ranging from 15 to 60 years was carried out from January 2004 to December 2004 at the Burns Centre, Department of Plastic, Reconstructive and Burns Surgery, Jubilee Mission Medical College and Research Institute, Thrissur, Kerala, India. There were 38 female and 12 male patients in the study group. Areas of burns ranging from 10% to 60% TBSA were included in the study. Daily dressings were done using autoclaved unripe papaya pulp smeared on potato peel dressing. The progress was assessed daily and application stopped when adequate debridement has been achieved or a maximum of 1 week. Statistical Analysis Used: None. Results: All 50 patients included initially completed the study. There were 38 females and 12 males. Papaya pulp was found to be a very effective debriding agent in all cases. Deep dermal wounds cleared up in 5 to 6 days and eschar in full thickness burns became loose by this period so that it needed minimal surgical debridement. The granulation tissue found following debridement with papaya pulp was pink and healthy. In patients who had to be taken up for grafting, a mild scraping was sufficient before placement of a

Full Text Available Objective: Kefir are natural probiotic compounds with anti-inflammatory properties, which were tested in experimental burn injury. Kefir gels were prepared from an extract of continuously cultured kefir in Man, Rogosa and Sharpe Broth medium for 48 and 96 h. Their extracts were used for evaluation of antibacterial effect against Pseudomonas aeruginosa in standard sample (ATCC 27853 and samples taken from patients with burns. The antibacterial effect of different kefir extract was assessment of minimum inhibitory concentration and minimum bactericidal concentration. The density of bacteria and percentage of organic acids (lactic and acetic acids were also determined. Materials and Methods: Similar burn injuries were made on dorsal skin surface of 40 rats. The rats were divided into 5 groups of 8 rats each. The base gel, silver sulfadiazine ointment, kefir 48 h gel, kefir 96 h gel were applied twice daily. Burn wound area was measured at baseline, 1 and 2 weeks. Results: Results indicated that by increasing the time of fermentation, concentration of lactic and acetic acid increased in orders of: Kefir 48 h < kefir 96 h, the end of the 2nd week the percentage of wound size were lowest in order of kefir 96 h gel < kefir grains 48 h gel < silver sulfadiazine 1% < untreated and based gel groups. Conclusion: In conclusion, the kefir gel therapy was an effective therapeutic approach to improve outcomes after severe burn when compared with conventional silver sulfadiazine treatment.

Wound pH affects a number of important factors in wound healing. It is known that the pH of the skin surface of healthy adults and children is 4.2-5.6 and that it decreases with the lapse of epithelialization. We measured the pH of the exudates from second degree burns in 26 cases. Among these, local burn wound infection developed in 6 cases. The causative organisms were Staphylococcus aureus in 2 cases and Staphylococcus epidermidis in 4 cases. The maximum pH value measured was 10.0 and the minimum was 5.0 for all samples. There were no differences in the initial measurements of pH between the non-infected cases and the local-infected cases. In cases of local infection, the pH rose prior to the onset of clinical signs of local burn infection. By consecutive measurement of pH, early detection of local wound infection can be achieved and this is very beneficial in clinical practice. Moreover, measurement is very easy and results are available immediately. In conclusion, consecutive pH measurement of exudates is considered to be a useful indicator in the treatment of second degree burns. Copyright © 2014 Elsevier Ltd and ISBI. All rights reserved.
Background The efficacy of Centella asiatica for incision and burn wounds are not fully understood. Here, we report the wound healing activities of sequential hexane, ethyl acetate, methanol, and water extracts of Centella asiatica in incision and partial-thickness burn wound models in rats. Methods Male Sprague–Dawley rats weighing 250–300 g were randomly divided into incision and burn wound groups. Each group was stratified into seven subgroups: (1) untreated; (2) NSS-; (3) Tween 20®- (vehicle control); (4) hexane extract-; (5) ethyl acetate extract-; (6) methanol extract-; and (7) aqueous extract-treated groups. The test substances were applied topically once daily. The tensile strength of the incision wound was measured on the seventh day after wound infliction. The general appearance and degree of wound healing of the burn wound were assessed on Days 3, 7, 10 and 14 after burn injury and prior to histopathological evaluation. Results On the seventh day after wound infliction, the tensile strength of incision wound in all extract-treated groups was significantly higher than that of the vehicle control (Tween 20®), but comparable to the NSS-treated group. The degrees of healing in the burn wound with the four extracts were significantly higher than that of the control on Days 3, 10 and 14. Histopathological findings on Day 14 after burn injury revealed prominent fibrinoid necrosis and incomplete epithelialization in the control and untreated groups, whereas fully developed epithelialization and keratinization were observed in all extract-treated groups. Analysis by thin layer chromatography demonstrated that the phyto-constituents β-sitosterol, asiatic acid, and asiaticoside and madecassocide were present in the hexane, ethyl acetate and methanol extracts, respectively. Conclusions All extracts of Centella asiatica facilitate the wound healing process in both incision and burn wounds. Asiatic acid in the ethyl acetate extract seemed to be the most active

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

Wound care is expensive and can cause immeasurable stress and inconvenience to patients and their significant others. It is therefore in the best interest of the patient, their significant others and the NHS as a whole that wounds are expertly assessed, managed and healed in the quickest timeframe possible. Nurses play a pivotal role in the process of accurate holistic wound assessment, evaluation and treatment. This article aims to help further develop and enhance both professional and clinical wound care assessment and evaluation skills. Pertinent wound care literature is critically reviewed and the crucial nature and important components of comprehensive wound assessment for facilitating the highest possible quality wound care to patients are presented alongside recommendations regarding how the enhanced knowledge and skills could be applied into everyday wound care practice.

The resuscitation of severe burn remains a controversial area within the burn care profession. There is ongoing debate as to what percentage burn is associated with a sufficient quality of life to support initial resuscitation efforts. We conducted a survey of delegates at the 39th Annual Meeting of the British Burns Association (2005), regarding attitudes towards resuscitation following major burns. Respondents were asked the maximum percentage total body surface area (TBSA) burn beyond which they would not wish to be resuscitated. They were also asked what maximum TBSA they perceived to be commensurate with an acceptable quality of life (QOL). One hundred and forty three of 300 delegates responded to the questionnaire. Thirty three percent of respondents would not wish to be resuscitated with 50-75% TBSA burns or greater. A further 35% would not wish to have life-sustaining intervention with 75-95% TBSA burns or greater. The remaining 32% indicated that they would not want resuscitation with TBSA burns>95%. Regardless of TBSA affected, 16% would not wish resuscitation if they had full thickness facial burns, a further 10% did not want resuscitation if both their hands and faces were affected. Our survey demonstrates the diversity of personal preference amongst burn care professionals. This would suggest that a unifying philosophy regarding the resuscitation of extensive burns will remain elusive.
There are a wide variety of dressing techniques and materials available for management of both acute wounds and chronic non-healing wounds. The primary objective in both the cases is to achieve a healed closed wound. However, in a chronic wound the dressing may be required for preparing the wound bed for further operative procedures such as skin grafting. An ideal dressing material should not only accelerate wound healing but also reduce loss of protein, electrolytes and fluid from the wound, and help to minimize pain and infection. The present dictum is to promote the concept of moist wound healing. This is in sharp contrast to the earlier practice of exposure method of wound management wherein the wound was allowed to dry. It can be quite a challenge for any physician to choose an appropriate dressing material when faced with a wound. Since wound care is undergoing a constant change and new products are being introduced into the market frequently, one needs to keep abreast of their effect on wound healing. This article emphasizes on the importance of assessment of the wound bed, the amount of drainage, depth of damage, presence of infection and location of wound. These characteristics will help any clinician decide on which product to use and where,in order to get optimal wound healing. However, there are no 'magical dressings'. Dressings are one important aspect that promotes wound healing apart from treating the underlying cause and other supportive measures like nutrition and systemic antibiotics need to be given equal attention.

Penetrating wounds in burn tissue may become infected, therefore primary closure of such wounds has only been recommended for lacerations of the face. To determine if wounds in burned areas can be closed primarily if seen early, we created partial- or full-thickness thermal burns in guinea pigs (n = 54) and made incisions through the burned tissue. One side was closed primarily at variable time intervals postburn. Infectious complications were determined by observation and the quantitative bacterial smear technique. All wounds closed primarily at 24 hours or longer postburn became infected. Wounds closed primarily at 4 hours postburn had fewer infectious complications than wounds left open (p less than 0.05). We also reviewed our experience with 23 multiply injured burn patients over an 11-year period who had peritoneal lavage or exploratory laparotomy. There were no wound infections in 12 patients with incisions closed primarily in unburned areas or in 11 patients with wounds through burned tissue. We conclude that lacerations or surgical incisions in burned tissues seen early (less than 12 hrs) postburn should be treated as wounds in unburned patients. Wounds in burned tissue seen late (greater than 24 hrs) postburn should be considered contaminated.

Statistics from various resources report that many patients in home healthcare settings have wounds. These vary from surgical, pressure, neuropathic, trauma, stasis, and venous wounds. These require the assessment, knowledge, and expertise of a clinician to assist them with wound care management. The purpose of this article is to identify and categorize types of wound care products appropriate for the various types of wounds that clinicians care for and manage in the home.

The purpose of this work is to improve a previous method developed by the authors for the classification of burn wounds into their depths. The inputs of the system are color and texture information, as these are the characteristics observed by physicians in order to give a diagnosis. Our previous work consisted in segmenting the burn wound from the rest of the image and classifying the burn into its depth. In this paper we focus on the classification problem only. We already proposed to use a Fuzzy-ARTMAP neural network (NN). However, we may take advantage of new powerful classification tools such as Support Vector Machines (SVM). We apply the five-folded cross validation scheme to divide the database into training and validating sets. Then, we apply a feature selection method for each classifier, which will give us the set of features that yields the smallest classification error for each classifier. Features used to classify are first-order statistical parameters extracted from the L*, u* and v* color components of the image. The feature selection algorithms used are the Sequential Forward Selection (SFS) and the Sequential Backward Selection (SBS) methods. As data of the problem faced here are not linearly separable, the SVM was trained using some different kernels. The validating process shows that the SVM method, when using a Gaussian kernel of variance 1, outperforms classification results obtained with the rest of the classifiers, yielding an error classification rate of 0.7% whereas the Fuzzy-ARTMAP NN attained 1.6 %.

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

Full Text Available This study aimed to clarify the effects of honey on acute-phase deep burn wounds. Two deep burn wounds were created on mice which were divided into four groups: no treatment, silver sulfadiazine, manuka honey, and Japanese acacia honey. Wound sizes were calculated as expanded wound areas and sampled 30 minutes and 1–4 days after wounding for histological observation. The wound sections were subjected to hematoxylin and eosin and immunohistological staining to detect necrotic cells, apoptotic cells, neutrophils, and macrophages. The no treatment group formed a scar. The redness around the wound edges in the silver sulfadiazine group was the most intense. All groups exhibited increased wound areas after wounding. The proportions of necrotic cells and the numbers of neutrophils in the manuka and acacia honey groups were lower than those in the no treatment and silver sulfadiazine groups until day 3; however, there were no significant differences between all groups on day 4. These results show that honey treatment on deep burn wounds cannot prevent wound progression. Moreover, comparing our observations with those of Jackson, there are some differences between humans and animals in this regard, and the zone of hyperemia and its surrounding area fall into necrosis, which contributes to burn wound progression.

The antibiotic-resistant bacteria are a major concern to wound care because of their ability to resist many of the antibiotics used today to treat infections. Consequently, other antimicrobials, in particular ionic silver, are considered ideal topical agents for effectively helping to manage and prevent local infections. Little is known about the antimicrobial efficacy of ionic silver on antibiotic-resistant bacteria at different pH values. Consequently, in this study our aim was to evaluate the effect of pH on the antimicrobial efficacy of a silver alginate (SA) and a silver carboxymethyl cellulose (SCMC) dressing on antibiotic-resistant bacteria isolated from burn patients. Forty-nine antibiotic-resistant bacteria, including Vancomycin-resistant Enterococcus faecium, meticillin-resistant Staphylococcus aureus, multidrug-resistant (MDR) Pseudomonas aeruginosa, MDR Vibrio sp, MDR Stenotrophomonas maltophilia, extended-spectrum ß-lactamase (ESBL) producing Salmonella sp, ESBL producing Klebsiella pneumoniae, ESBL producing Proteus mirabilis, ESBL producing Escherichia coli and MDR Acinetobacter baumannii, routinely isolated from burn wounds were used in the study and evaluated for their susceptibility to two silver containing wound dressings using a standardised antimicrobial efficacy screening assay [corrected zone of inhibition (CZOI)]. The mean overall CZOI for the Gram-positive isolates at a pH of 5·5 were very similar for both dressings. A mean CZOI of 5 mm was recorded for the SCMC dressing, which was slightly higher, at 5·4 mm for the SA dressing. At a pH of 7·0 both dressings, in general, showed a similar activity. However, at a pH of 8·5 the mean CZOI of the SCMC dressing was found to be significantly (P bacteria followed a similar pattern as observed with the Gram-positive bacteria. Susceptibility to silver ions did vary significantly between genera and species of bacteria. Interestingly, when pH was changed from 8·5 to 5·5 antimicrobial activity

Full Text Available The management of pain in patients with burn wounds is complex and problematic. Burn-wound pain is severe, inconsistent and underestimated. Patients experience severe pain, especially during procedures, until wound healing has occurred. A multi-modality approach is needed for effective management of pain, which requires an understanding of the mechanisms of pain. Altered pharmacokinetics and pharmacodynamics in burn-wound patients makes drug actions unpredictable. Opioids alone are seldom sufficient for pain control. The multi-modality approach includes the use of opioids and non-steroidal antiinflammatory, anxiolytic and alternative drugs. Ketamine has been found to be a useful agent for analgesia in burn-wound patients; a dose of 10 mg/kg qid per os was found to be an effective adjunct to pain therapy.

Emerging bacterial resistance to multiple drugs is an increasing problem in burn wound management. New non-pharmacologic interventions are needed for burn wound disinfection. Here we report on a novel physical method for disinfection: antiseptic pulsed electric field (PEF) applied externally to the infected burns. In a mice model, we show that PEF can reduce the load of multidrug resistant Acinetobacter baumannii present in a full thickness burn wound by more than four orders of magnitude, as detected by bioluminescence imaging. Furthermore, using a finite element numerical model, we demonstrate that PEF provides non-thermal, homogeneous, full thickness treatment for the burn wound, thus, overcoming the limitation of treatment depth for many topical antimicrobials. These modeling tools and our in vivo results will be extremely useful for further translation of the PEF technology to the clinical setting, as they provide the essential elements for planning of electrode design and treatment protocol.

Natural ingredients are of increasing interest within the field of dermatology. Bensal HP, an ointment containing 3% oak bark extract, 3% salicylic acid, and 6% benzoic acid, is believed to be efficacious against a variety of inflammatory and infectious dermatidites. Here we evaluate Bensal HP's ability to influence wound healing, which has yet to be studied in this setting. Bensal HP applied to burn wounds on the dorsal surface of BALB/c mice significantly attenuated wound expansion in the first few days post-injury as compared to controls. Histological analysis mirrored these findings with accelerated maturation of the wound bed and increased collagen deposition by the end of the study period. Cytokine analysis revealed decreased IL-6 and TNFα secretion in the Bensal HP-treated burns as compared to controls. Similarly, excisional wounds treated with Bensal HP demonstrated comparable wound healing as compared to controls with positive histologic features and increased collagen deposition. Furthermore, IL-6 production was attenuated in the Bensal-HP treated wounds at day 3, with no differences appreciated in IL-6 at day 7 or in TNFα at either time point. While Bensal-HP represents a therapeutic strategy to enhance the histologic and immunologic milieu in burn and excisional wounds, further study is needed to fully elucidate the full potential of this treatment.

Successful wound healing depends on various factors, including exudate control, prevention of microbial contaminants, and moisture balance. We report two cases of managing burn wounds with SMARTPORE Technology polyurethane foam dressing. In Case 1, a 2-year-old Asian girl presented with a delayed (11 days) wound on her right leg. She sustained a thermal injury from a hot iron that was left idle on the floor. Clinical inspection revealed an infected wound with overlying eschar that traversed her knee joint. As her parents refused surgical debridement under general anesthesia, hydrotherapy and wound dressing using SMARTPORE Technology Polyurethane foam were used. Despite the delay in presentation of this linear thermal pediatric burn injury that crossed the knee joint, the patient's response to treatment and its outcome were highly encouraging. She was cooperative and tolerated each dressing change without the need of supplemental analgesia. Her wound was healed by 24 days post-admission. In Case 2, a 25-year-old Asian man presented with a mixed thickness thermal flame burn on his left leg. On examination, the injury was a mix of deep and superficial partial thickness burn, comprising approximately 3% of his total body surface area. SMARTPORE Technology polyurethane foam was used on his wound; his response to the treatment was very encouraging as the dressing facilitated physiotherapy and mobility. The patient rated the pain during dressing change as 2 on a scale of 10 and his pain score remained the same in every subsequent change. His wound showed evidence of epithelialization by day 7 post-burn. There were no adverse events reported. Managing burn wounds with SMARTPORE Technology polyurethane foam resulted in reduced pain during dressing changes and the successful healing of partial and mixed thickness wounds. The use of SMARTPORE Technology polyurethane foam dressings showed encouraging results and requires further research as a desirable management option in

Hyperspectral imaging (HSI) is a noncontact and noninvasive optical modality emerging the field of medical research. The goal of this study was to determine the ability of HSI and image segmentation to discriminate burn wounds in a preclinical porcine model. A heated brass rod was used to introduce burn wounds of graded severity in a pig model and a sequence of hyperspectral data was recorded up to 8-h postinjury. The hyperspectral images were processed by an unsupervised spectral-spatial segmentation algorithm. Segmentation was validated using results from histology. The proposed algorithm was compared to K-means segmentation and was found superior. The obtained segmentation maps revealed separated zones within the burn sites, indicating a variation in burn severity. The suggested image-processing scheme allowed mapping dynamic changes of spectral properties within the burn wounds over time. The results of this study indicate that unsupervised spectral-spatial segmentation applied on hyperspectral images can discriminate burn injuries of varying severity.

Introduction Deep burn wounds undergo a dynamic process known as wound progression that results in a deepening and extension of the initial burn area. The zone of stasis is more likely to develop more severe during wound progression in the presence of hypoperfusion. Hydrogen has been reported to alleviate injury triggered by ischaemia/reperfusion and burns in various organs by selectively quenching oxygen free radicals. The aim of this study was to investigate the possible protective effects of hydrogen against early burn-wound progression. Methods Deep-burn models were established through contact with a boiled, rectangular, brass comb for 20 s. Fifty-six Sprague-Dawley rats were randomly divided into sham, burn plus saline, and burn plus hydrogen-rich saline (HS) groups with sacrifice and analysis at various time windows (6 h, 24 h, 48 h) post burn. Indexes of oxidative stress, apoptosis and autophagy were measured in each group. The zone of stasis was evaluated using immunofluorescence staining, ELISA, and Western blot to explore the underlying effects and mechanisms post burn. Results The burn-induced increase in malondialdehyde was markedly reduced with HS, while the activities of endogenous antioxidant enzymes were significantly increased. Moreover, HS treatment attenuated increases in apoptosis and autophagy postburn in wounds, according to the TUNEL staining results and the expression analysis of Bax, Bcl-2, caspase-3, Beclin-1 and Atg-5 proteins. Additionally, HS lowered the level of myeloperoxidase and expression of TNF-α, IL-1β, and IL-6 in the zone of stasis while augmenting IL-10. The elevated levels of Akt phosphorylation and NF-κB p65 expression post burn were also downregulated by HS management. Conclusion Hydrogen can attenuate early wound progression following deep burn injury. The beneficial effect of hydrogen was mediated by attenuating oxidative stress, which inhibited apoptosis and inflammation, and the Akt/NF-κB signalling pathway may be

Crocodile oil and its products are used as ointments for burns and scalds in traditional medicines. A new ointment formulation - crocodile oil burn ointment (COBO) was developed to provide more efficient wound healing activity. The purpose of the study was to evaluate the burn healing efficacy of this new formulation by employing deep second-degree burns in a Wistar rat model. The analgesic and anti-inflammatory activities of COBO were also studied to provide some evidences for its further use. The wound healing potential of this formulation was evaluated by employing a deep second-degree burn rat model and the efficiency was comparatively assessed against a reference ointment - (1% wt/wt) silver sulfadiazine (SSD). After 28 days, the animals were euthanized and the wounds were removed for transversal and longitudinal histological studies. Acetic acid-induced writhing in mice was used to evaluate the analgesic activity and its anti-inflammatory activity was observed in xylene -induced edema in mice. COBO enhanced the burn wound healing (20.5±1.3 d) as indicated by significant decrease in wound closure time compared with the burn control (25.0±2.16 d) ( P hand, the analgesic and anti-inflammatory activity of COBO were much better than those of control group, while they were very close to those of moist exposed burn ointment (MEBO). COBO accelerated wound closure, reduced inflammation, and had analgesic effects compared with SSD in deep second degree rat burn model. These findings suggest that COBO would be a potential therapy for treating human burns. Abbreviations: COBO, crocodile oil burn ointment; SSD, silver sulfadiazine; MEBO, moist exposed burn ointment; TCM, traditional Chinese medicine; CHM, Chinese herbal medicine; GC-MS, gas chromatography-mass spectrometry.
Full Text Available The aim of the present study was to visualize the benefits and advantages derived from preparations based on extracts of bee pollen as compared to pharmaceuticals commonly used in the treatment of burns. The bee pollen ointment was applied for the first time in topical burn treatment. Experimental burn wounds were inflicted on two white, domestic pigs. Clinical, histopathological, and microbiological assessment of specimens from burn wounds, inflicted on polish domestic pigs, treated with silver sulfadiazine or bee pollen ointment, was done. The comparative material was constituted by either tissues obtained from wounds treated with physiological saline or tissues obtained from wounds which were untreated. Clinical and histopathological evaluation showed that applied apitherapeutic agent reduces the healing time of burn wounds and positively affects the general condition of the animals. Moreover the used natural preparation proved to be highly effective antimicrobial agent, which was reflected in a reduction of the number of microorganisms in quantitative research and bactericidal activity of isolated strains. On the basis of the obtained bacteriological analysis, it may be concluded that the applied bee pollen ointment may affect the wound healing process of burn wounds, preventing infection of the newly formed tissue.

In burn wounds early discrimination between the different depths plays an important role in the treatment strategy. The remaining vasculature in the wound determines its healing potential. Non-invasive measurement tools that can identify the vascularization are therefore considered to be of high diagnostic importance. Thermography is a non-invasive technique that can accurately measure the temperature distribution over a large skin or tissue area, the temperature is a measure of the perfusion of that area. The aim of this study was to investigate the clinimetric properties (i.e. reliability and validity) of thermography for measuring burn wound depth. In a cross-sectional study with 50 burn wounds of 35 patients, the inter-observer reliability and the validity between thermography and Laser Doppler Imaging were studied. With ROC curve analyses the ΔT cut-off point for different burn wound depths were determined. The inter-observer reliability, expressed by an intra-class correlation coefficient of 0.99, was found to be excellent. In terms of validity, a ΔT cut-off point of 0.96°C (sensitivity 71%; specificity 79%) differentiates between a superficial partial-thickness and deep partial-thickness burn. A ΔT cut-off point of -0.80°C (sensitivity 70%; specificity 74%) could differentiate between a deep partial-thickness and a full-thickness burn wound. This study demonstrates that thermography is a reliable method in the assessment of burn wound depths. In addition, thermography was reasonably able to discriminate among different burn wound depths, indicating its potential use as a diagnostic tool in clinical burn practice.

Changing daily wound dressings provokes a substantial amount of pain in patients with severe burn wounds. Pharmacological analgesics alone often are inadequate to solve this problem. This study explored whether immersive virtual reality (VR) can reduce the procedural pain and anxiety during an entire wound care session and compared VR to the effects of standard care and other distraction methods. Nineteen inpatients ages 8 to 65 years (mean, 30 years) with a mean TBSA of 7.1% (range, 0.5-21.5%) were studied using a within-subject design. Within 1 week of admission, standard care (no distraction), VR, or another self-chosen distraction method was administered during the wound dressing change. Each patient received the normal analgesic regimen. Pain was measured with visual analog thermometer scores, and anxiety was measured with the state-version of the Spielberger State Trait Anxiety Inventory. After comparing different distraction methods, only VR and television showed significant pain reductions during wound dressing changes. The effects of VR were superior, but not statistical significant, to that of television. Thirteen of 19 patients reported clinically meaningful (33% or greater) reductions in pain during VR distraction. No side effects were reported. No correlations were found between the reduction in pain ratings and patient variables like age, sex, duration of hospital stay, or percentage of (deep) burns. There was no significant reduction of anxiety ratings.

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

Many wound management protocols have been developed to improve wound healing after burn with the primordial aim to restore the barrier function of the skin and also provide a better esthetic outcome. Autologous skin grafts remain the gold standard in the treatment of skin burn, but this treatment has its limitation especially for patients presenting limited donor sites due to extensive burn areas. Deep burn injuries also alter the integrity of skin-sensitive innervation and have an impact on patient's quality of life by compromising perceptions of touch, temperature, and pain. Thus, patients can suffer from long-term disabilities ranging from cutaneous sensibility loss to chronic pain. The cellular mechanisms involved in skin reinnervation following injury are not elucidated yet. Depending on the depth of the burn, nerve sprouting can occur from the wound bed or the surrounding healthy tissue, but somehow this process fails to provide correct reinnervation of the wound during scarring. In addition, several clinical observations indicate that damage to the peripheral nervous system influences wound healing, resulting in delayed wound healing or chronic wounds, underlining the role of innervation and neuromediators for normal cutaneous tissue repair development. Promising tissue engineering strategies, including the use of biomaterials, skin substitutes, and stem cells, could provide novel alternative treatments in wound healing and help in improving patient's sensory recovery.

Although the overall incidence of and mortality rate associated with burn injury have decreased in recent decades, burns remain a significant source of morbidity and mortality in children. Children with major burns require emergent resuscitation. Resuscitation is similar to that for adults, including pain control, airway management, and administration of intravenous fluid. However, in pediatrics, fluid resuscitation is needed for burns greater than or equal to 15% of total body surface area (TBSA) compared with burns greater than or equal to 20% TBSA for adults. Unique to pediatrics is the additional assessment for non-accidental injury and accurate calculation of the percentage of total burned surface area (TBSA) in children with changing body proportions are crucial to determine resuscitation parameters, prognosis, and disposition.

To compare the effects on wound bed of deep burn following eschar excision with different wound management in rabbits. Eighteen full-thickness burns models of Japanese white rabbits were established. They were randomly divided into 3 groups of traditional dressing, biological dressing and negative pressure wound therapy (NPWT) (n=6 each), according to the random number table. Eschar excision was performed three days later. The wound bed was observed and wound tissue was harvested for counting the quantity of bacteria, tissue dry wet ratio, measuring the level of tumor necrosis factor alpha (TNF-α), interleukin (IL)-1β and IL-6, the amount of collagen fibers and the microvessel density instantly and again seven days later. Statistical analyses were performed. The NPWT group was better than other groups by observing the wound bed. The quantity of bacteria of traditional dressing group, biological dressing group and NPWT group at the time point of seven days after escharectomy turned out to be (9.4±1.5)×10(4,) (8.1±2.7)×10(4,) (3.9±0.7)×10(4) cfu/g, the NPWT group was significantly lower than traditional dressing group and biological dressing group (both P0.05). The IL-6 of biological dressing group was higher than that of traditional dressing group at the time point of seven days after the eschar excision was performed[(94±10) vs (76±8) ng/L, P<0.05]. The amount of collagen fibers of three group at the time point of seven days after escharectomy turned out to be (60±9), (55±12), (77±17). The NPWT group was significantly higher than traditional dressing group and biological dressing group (P<0.05), and all higher than that at the time point of the day when escharectomy was performed[(39±6), (39±11), (38±6)](all P<0.05). The microvessel density of three groups at the time point of seven days after escharectomy turned out to be (42±6), (53±4), (82±10). The NPWT group was higher than that of the other two groups, and biological dressing group was

Burns and the associated wound care procedures can be extremely painful and anxiety-provoking for children. Burn injured children and adolescents are therefore at greater risk of experiencing a range of psychological reactions, in particular posttraumatic stress disorder, which can persist for months to years after the injury. Non-pharmacological intervention is critical for comprehensive pain and anxiety management and is used alongside pharmacological analgesia and anxiolysis. However, effective non-pharmacological pain and anxiety management during pediatric burn procedures is an area still needing improvement. Medical hypnosis has received support as a technique for effectively decreasing pain and anxiety levels in adults undergoing burn wound care and in children during a variety of painful medical procedures (e.g., bone marrow aspirations, lumbar punctures, voiding cystourethrograms, and post-surgical pain). Pain reduction during burn wound care procedures is linked with improved wound healing rates. To date, no randomized controlled trials have investigated the use of medical hypnosis in pediatric burn populations. Therefore this study aims to determine if medical hypnosis decreases pain, anxiety, and biological stress markers during wound care procedures; improves wound healing times; and decreases rates of traumatic stress reactions in pediatric burn patients. This is a single-center, superiority, parallel-group, prospective randomized controlled trial. Children (4 to 16 years, inclusive) with acute burn injuries presenting for their first dressing application or change are randomly assigned to either the (1) intervention group (medical hypnosis) or (2) control group (standard care). A minimum of 33 participants are recruited for each treatment group. Repeated measures of pain, anxiety, stress, and wound healing are taken at every dressing change until ≥95 % wound re-epithelialization. Further data collection assesses impact on posttraumatic stress

Full Text Available Abstract Background The use of honey as a natural product of Apis spp. for burn treatment has been widely applied for centuries. Tualang honey has been reported to have antibacterial properties against various microorganisms, including those from burn-related diagnoses, and is cheaper and easier to be absorbed by Aquacel dressing. The aim of this study is to evaluate the potential antibacterial properties of tualang honey dressing and to determine its effectiveness as a partial thickness burn wound dressing. Methods In order to quantitate the bioburden of the swabs, pour plates were performed to obtain the colony count (CFU/ml. Swabs obtained from burn wounds were streaked on blood agar and MacConkey agar for bacterial isolation and identification. Later, antibacterial activity of Aquacel-tualang honey, Aquacel-Manuka honey, Aquacel-Ag and Aquacel- plain dressings against bacteria isolated from patients were tested (in-vitro to see the effectiveness of those dressings by zone of inhibition assays. Results Seven organisms were isolated. Four types of Gram-negative bacteria, namely Enterobacter cloacae, Klebsiella pneumoniae, Pseudomonas spp. and Acinetobacter spp., and three Gram-positive bacteria, namely Staphylococcus aureus, coagulase-negative Staphylococcus aureus (CONS and Streptococcus spp., were isolated. Total bacterial count decreased on day 6 and onwards. In the in-vitro antibacterial study, Aquacel-Ag and Aquacel-Manuka honey dressings gave better zone of inhibition for Gram positive bacteria compared to Aquacel-Tualang honey dressing. However, comparable results were obtained against Gram negative bacteria tested with Aquacel-Manuka honey and Aquacel-Tualang honey dressing. Conclusions Tualang honey has a bactericidal as well as bacteriostatic effect. It is useful as a dressing, as it is easier to apply and is less sticky compared to Manuka honey. However, for Gram positive bacteria, tualang honey is not as effective as usual care

Objective: To validate the clinical effect of three dimensional human body scanning system BurnCalc developed by our research team in the evaluation of burn wound area. Methods: A total of 48 burn patients treated in the outpatient department of our unit from January to June 2015, conforming to the study criteria, were enrolled in. For the first 12 patients, one wound on the limbs or torso was selected from each patient. The stability of the system was tested by 3 attending physicians using three dimensional human body scanning system BurnCalc to measure the area of wounds individually. For the following 36 patients, one wound was selected from each patient, including 12 wounds on limbs, front torso, and side torso, respectively. The area of wounds was measured by the same attending physician using transparency tracing method, National Institutes of Health (NIH) Image J method, and three dimensional human body scanning system BurnCalc, respectively. The time for getting information of 36 wounds by three methods was recorded by stopwatch. The stability among the testers was evaluated by the intra-class correlation coefficient (ICC). Data were processed with randomized blocks analysis of variance and Bonferroni test. Results: (1) Wound area of patients measured by three physicians using three dimensional human body scanning system BurnCalc was (122±95), (121±95), and (123±96) cm(2,) respectively, and there was no statistically significant difference among them ( F =1.55, P >0.05). The ICC among 3 physicians was 0.999. (2) The wound area of limbs of patients measured by transparency tracing method, NIH Image J method, and three dimensional human body scanning system BurnCalc was (84±50), (76±46), and (84±49) cm(2,) respectively. There was no statistically significant difference in the wound area of limbs of patients measured by transparency tracing method and three dimensional human body scanning system BurnCalc ( P >0.05). The wound area of limbs of patients

Multispectral imaging (MSI) is an optical technique that measures specific wavelengths of light reflected from wound site tissue to determine the severity of burn wounds. A rapid MSI device to measure burn depth and guide debridement will improve clinical decision making and diagnoses. We used a porcine burn model to study partial thickness burns of varying severity. We made eight 4 × 4 cm burns on the dorsum of one minipig. Four burns were studied intact, and four burns underwent serial tangential excision. We imaged the burn sites with 400-1000 nm wavelengths. Histology confirmed that we achieved various partial thickness burns. Analysis of spectral images show that MSI detects significant variations in the spectral profiles of healthy tissue, superficial partial thickness burns, and deep partial thickness burns. The absorbance spectra of 515, 542, 629, and 669 nm were the most accurate in distinguishing superficial from deep partial thickness burns, while the absorbance spectra of 972 nm was the most accurate in guiding the debridement process. The ability to distinguish between partial thickness burns of varying severity to assess whether a patient requires surgery could be improved with an MSI device in a clinical setting.

Full Text Available A non-healing wound is defined as showing no measurable signs of healing for at least 30 consecutive treatments with standard wound care.  It is a snapshot of a patient′s total health as well as the ongoing battle between noxious factors and the restoration of optimal macro and micro circulation, oxygenation and nutrition. In practice, standard therapies for non-healing cutaneous wounds include application of appropriate dressings, periodic debridement and eliminating causative factors.  The vast majority of wounds would heal by such approach with variable degrees of residual morbidity, disability and even mortality. Globally, beyond the above therapies, newer tools of healing are selectively accessible to caregivers, for various logistical or financial reasons. Our review will focus on the use of hyperbaric oxygen therapy (HBOT, as used at our institution (CAMC, and some other modalities that are relatively accessible to patients. HBOT is a relatively safe and technologically simpler way to deliver care worldwide. However, the expense for including HBOT as standard of care for recognized indications per UHMS(Undersea and Hyperbaric Medical Society may vary widely from country to country and payment system.  In the USA, CMS (Centers for Medicare and Medicaid Services approved indications for HBOT vary from that of the UHMS for logistical reasons.  We shall also briefly look into other newer therapies per current clinical usage and general acceptance by the medical community. Admittedly, there would be other novel tools with variable success in wound healing worldwide, but it would be difficult to include all in this treatise.

The basic and clinical research in wound healing have made great progress in China in the past 50 years. The method of "intermingle skin transplantation" which was first advocated by surgeons of Ruijin Hospital in 1966 greatly reduced the amount of autologous donor skin, thus making the coverage of an extensive burn wound possible. This method is also known as "Chinese therapy". In 1986, doctors of Jishuitan Hospital reported successful coverage of an extensive burn wound with microautografts and allogeneic skin. The basic research of wound healing has been carried out since 1992, a series of studies showed the characteristics of biological behaviours of cells in concern, extracellular matrix and growth factor, the mechanism underlying progressive injury in deep second burn wound, the effect of "skin island" and the local immune tolerance induced by it (which are the key factors of intermingle transplantation). The induction of local immune tolerance has now become the research hot subject of skin transplantation immunology. Stem cell research in the field of wound healing has been extensively carried out. The theory of "dermal template defection" has been proposed as one of the mechanisms of scar formation. On the other hand, great progress has been achieved in the treatment of burns on the basis of clinical researches. Doctors of PLA 304 hospital found that excision of eschar on patients with extensive deep burn injury at early shock stage greatly decreased the occurrence of complications and mortality. Doctors of Ruijin Hospital reported that healing of deep second burn wound could be improved by tangential excision of burn eschar within 24 hours after burn injury. Doctors of Xiangya Hospital reported patients suffering from deep burns of the hands got satisfied functional restoration when treated with tangential excision of eschar while degraded dermal tissue could be retained with transplantation of autoskin grafts.

Wound healing activity of methanol extract of Alternanthera brasiliana [5% (w/w) ointment] was evaluated in experimental burn wound model in rats. Healing potential was assessed by the rate of wound contraction, estimation of anti-oxidants like catalase, superoxide dismutase, reduced glutathione, protein, vitamin C and hydroxyproline, along with histopathological examination on 8th day post wounding. The statistical data indicated that there was significant increase in wound contraction along with augmented level of antioxidants in granulation tissues in A. brasiliana treated group. Histopathological assessment of the granulation tissue revealed formation of epidermis with keratin layer and deposition of collagen fibers after treatment with the plant extract.
This article describes a local involvement in a project to evaluate a remote system of wound management, incorporating the use of digital and mobile technology. It outlines how this involvement influenced the current system of 'tele wound care' (remote wound management) in a large community organisation. The system allows remote wound assessment, management advice and ongoing monitoring of wounds to ensure that the dressing choice remains appropriate and that timely wound care support can be provided to community nurses, practice nurses and GPs.

The high contrast resolution afforded by terahertz (1 THz = 1012 Hz) imaging of physiologic tissue continues to drive explorations into the utility of THz technology for burn wound detection. Although we have previously reported the use of a novel, reflective THz imaging technology to sense spatiotemporal differences in reflectivity between partial and full thickness burn wounds, no evidence exists of a one-to-one correlation between structural damage observed in histological assessments of burn severity and THz signal. For example, varying burn induction methods may all result in a common burn wound severity, however, burn features observed in parallel THz imagery may not be identical. Successful clinical translation of THz technology as a comprehensive burn guidance tool, therefore, necessitates an understanding of THz signal and its relation to wound pathophysiology. In this work, longitudinal THz imagery was acquired with a quartz (n = 2.1, 500 μm) window of cutaneous wounds induced with the same brand geometry and contact pressure but varying contact times (5, 7, and 10 seconds) in in vivo, pre-clinical rat models (n=3) over a period of 3 days. Though all burn wounds were evaluated to be deep partial thickness with histology, THz contrasts observed for each burn contact time were intrinsically unique. This is the first preliminary in vivo evidence of a many-to-one relationship between changes in THz contrast and burn severity as ascertained by histology. Future large-scale studies are required to assess whether these observed changes in THz contrast may be interpreted as physiological changes occurring over time, morphometric changes related to anatomical change, or electromagnetic changes between dielectric substrate windows and the underlying tissue.
Full Text Available 【Abstract】The larvae of musca domestica were put in use to discard the dead tissue of a case of severe burn. A total of 50 000 aseptic maggots were put onto the infective wound surface, and aseptic dressings overlaid the surface. Three days later, another 20 000 maggots were put onto the wound for the second therapy. After twice maggot debridement, most necrotic muscle tissues of the wound were cleaned up, and eventually fresh granulation tissue grew and later the wound was covered and healed by 3 times of skin grafting. The result demonstrates that maggot therapy is safe and effective with no adverse complications except pain. Key words: Biological therapy; Wound infection; Burns; Wound healing; Debridement

Full Text Available Burn care is a huge challenge in India, having the highest female mortality globally due to flame burns. Burns can happen anywhere, but are more common in the rural region, affecting the poor. Most common cause is flame burns, the culprit being kerosene and flammable flowing garments worn by the women. The infrastructure of healthcare network is good but there is a severe resource crunch. In order to bring a positive change, there will have to be more trained personnel willing to work in the rural areas. Strategies for prevention and training of burn team are discussed along with suggestions on making the career package attractive and satisfying. This will positively translate into improved outcomes in the burns managed in the rural region and quick transfer to appropriate facility for those requiring specialised attention.

Chronic wounds are a major healthcare problem costing the United States billions of dollars a year. The American Academy of Dermatology has underscored the significance of wound care in dermatological practice. It is critical for all dermatologists to understand the elements of diagnosis and therapy. We emphasize major aspects of diagnosis and present a simple classification of wound dressings with guidelines for usage and relative cost data. After completing this learning activity, participants should be able to diagnose common types of chronic wounds, formulate a therapeutic plan, and describe the major classes of topical therapies and dressings for the chronic wound.

Terahertz electromagnetic waves have long been proposed to be ideal for spectroscopy and imaging through non-polar dielectric materials that contain no water. Terahertz radiation may thus be useful for monitoring burn and wound injury recovery, as common care treatments involve application of both a clinical dressing and topical ointment. Here, we investigate the optical properties of typical care treatments in the millimeter wave (150–300 GHz), terahertz (0.3–3 THz), and infrared (14.5–0.67 μm) ranges of the electromagnetic spectrum. We find that THz radiation realizes low absorption coefficients and high levels of transmission compared to infrared wavelengths, which were strongly attenuated. Terahertz imaging can enable safe, non-ionizing, noninvasive monitoring of the healing process directly through clinical dressings and recovery ointments, minimizing the frequency of dressing changes and thus increasing the rate of the healing process.

To investigate the effect of topical application of insulin on the burn wound healing in aging diabetes mellitus (DM) rats and to explore its mechanism. Seventy-five SPF Wistar rats (female and/or male), aged 12-24 months and weighing 300-350 g, were selected and randomly divided into group A (burn control group, n=25), group B (DM burn control group, n=25), and group C (DM insulin treatment group, n=25). The rats in group B and group C were fed with high-fat, high-protein, and high-sugar forage for 1 month and received intraperitoneal injection of streptozotocin (STZ) to establish experimental model of aging DM. The rats were fed with high-fat, high-protein, and high-sugar forage for another 8 weeks. Then, the deep second-degree burn model was established in the rats of group B and group C. The wounds in group A and B underwent local subcutaneous injection of 2 mL isotonic saline and group C received local subcutaneous injection of 0.1 U insulin. The rate of wound healing was calculated 7, 14, and 21 days after burn injury. At 1, 3, 7, 14, and 21 days after burn injury, HE staining observation, immunohistochemistry staining for CD34, detection of sugar and hydroxyproline (HOP) content in wound tissue, and microvessel density (MVD) calculation were performed. At 7, 14, and 21 days after burn injury, the wound healing rates of group A and group C was significantly higher than that of group B (P 0.05). Histology observation at 21 days after burn injury: in group A, certain degree of epithelization was evident in the wound epithelium; in group B, large quantity of necrotic tissue was evident; in group C, complete epithelization occurred in the wound epithelium with better epithelial cell differentiation and more neonatal collagen. For the sugar content in the wound tissue, group A was significantly lower than group B or group C at 1, 3, 7, 14, and 21 days (P wound tissue and the MVD count, group A or group C was significantly higher than group B (P 0.05).

To provide information about a study using a new process for continuous monitoring to improve chronic wound care quality.This continuing education activity is intended for physicians, physician assistants, nurse practitioners, and nurses with an interest in skin and wound care.After completing this continuing education activity, you should be better able to:1. Recognize problems associated with chronic wound care.2. Identify methods used in this project to improve care.3. Illustrate the findings from this and similar projects and implications for providing improved wound care.Patients with chronic wounds require complex care because of comorbidities that can affect healing. Therefore, the goal of this project was to develop a system of reviewing all hospitalized patients seen by the study authors' wound care service on a weekly basis to decrease readmissions, morbidity, and mortality. Weekly multidisciplinary conferences were conducted to evaluate patient data and systematically assess for adherence to wound care protocols, as well as to create and modify patient care plans. This review of pathology and the performance of root-cause analyses often led to improved patient care.

This study was designed to adapt a surgical wound care algorithm that is used to provide evidence-based surgical wound care in a critical care unit. This study used, the 'ADAPTE process', an international clinical practice guideline development method. The 'Bonnie Sue wound care algorithm' was used as a draft for the new algorithm. A content validity index (CVI) targeting 135 critical care nurses was conducted. A 5-point Likert scale was applied to the CVI test using a statistical criterion of .75. A surgical wound care algorithm comprised 9 components: wound assessment, infection control, necrotic tissue management, wound classification by exudates and depths, dressing selection, consideration of systemic factors, wound expected outcome, reevaluate non-healing wounds, and special treatment for non-healing wounds. All of the CVI tests were ≥.75. Compared to existing wound care guidelines, the new wound care algorithm provides precise wound assessment, reliabilities of wound care, expands applicability of wound care to critically ill patients, and provides evidence and strength of recommendations. The new surgical wound care algorithm will contribute to the advancement of evidence-based nursing care, and its use is expected as a nursing intervention in critical care.
Full Text Available The widespread existence of unhealed wounds, ulcers, and burns has a great impact on public health and economy. Many interventions, including new medications and technologies, are being used to help achieve significant wound healing and to eliminate infections. Therefore, to find an intervention that has both therapeutic effect on the healing process and the ability to kill microbes is of great value. Honey is a natural product that has been recently introduced in modern medical practice. Honey's antibacterial properties and its effects on wound healing have been thoroughly investigated. Laboratory studies and clinical trials have shown that honey is an effective broad-spectrum antibacterial agent. This paper reviews data that support the effectiveness of natural honey in wound healing and its ability to sterilize infected wounds. Studies on the therapeutic effects of honey collected in different geographical areas on skin wounds, skin and gastric ulcers, and burns are reviewed and mechanisms of action are discussed. (Ulcers and burns are included as an example of challenging wounds. The data show that the wound healing properties of honey include stimulation of tissue growth, enhanced epithelialization, and minimized scar formation. These effects are ascribed to honey's acidity, hydrogen peroxide content, osmotic effect, nutritional and antioxidant contents, stimulation of immunity, and to unidentified compounds. Prostaglandins and nitric oxide play a major role in inflammation, microbial killing, and the healing process. Honey was found to lower prostaglandin levels and elevate nitric oxide end products. These properties might help to explain some biological and therapeutic properties of honey, particularly as an antibacterial agent or wound healer. The data presented here demonstrate that honeys from different geographical areas have considerable therapeutic effects on chronic wounds, ulcers, and burns. The results encourage the use of honey

According to the latest report from the World Health Organization, an estimated 265,000 deaths still occur every year as a direct result of burn injuries. A widespread range of these deaths induced by burn wound happens in low- and middle-income countries, where survivors face a lifetime of morbidity. Most of the deaths occur due to infections when a high percentage of the external regions of the body area is affected. Microbial nutrient availability, skin barrier disruption, and vascular supply destruction in burn injuries as well as systemic immunosuppression are important parameters that cause burns to be susceptible to infections. Topical antimicrobials and dressings are generally employed to inhibit burn infections followed by a burn wound therapy, because systemic antibiotics have problems in reaching the infected site, coupled with increasing microbial drug resistance. Nanotechnology has provided a range of molecular designed nanostructures (NS) that can be used in both therapeutic and diagnostic applications in burns. These NSs can be divided into organic and non-organic (such as polymeric nanoparticles (NPs) and silver NPs, respectively), and many have been designed to display multifunctional activity. The present review covers the physiology of skin, burn classification, burn wound pathogenesis, animal models of burn wound infection, and various topical therapeutic approaches designed to combat infection and stimulate healing. These include biological based approaches (e.g. immune-based antimicrobial molecules, therapeutic microorganisms, antimicrobial agents, etc.), antimicrobial photo- and ultrasound-therapy, as well as nanotechnology-based wound healing approaches as a revolutionizing area. Thus, we focus on organic and non-organic NSs designed to deliver growth factors to burned skin, and scaffolds, dressings, etc. for exogenous stem cells to aid skin regeneration. Eventually, recent breakthroughs and technologies with substantial potentials in tissue

Chronic wounds are a major healthcare problem costing billions of dollars a year over the world. However, it is regrettable that a large number of chronic wounds are still treated simply by conventional dressing change in local clinics, lacking of definite diagnosis and personalized care. This situation results in a low wound healing rate, unsatisfied life quality of the patients, and higher medical cost for the prolonged promiscuous care. We should not only emphasize the importance of wound care in clinical practice, but also emphasize the importance of establishing wound care centers. With the experience of our practice in wound care center, the construction of wound care technology platform is strongly suggested. This platform could act as an education base to train more professional wound care doctors, nurses, and care workers, as well as resolve many technical difficulties involved in the treatment of many complicated chronic wounds.

Our various previous findings have shown the suitability of norfloxacin in the treatment of bacterial infections and burn wounds in alone as well as in combination with Curcuma longa in various topical (ointments, gels, and creams) and transdermal drug delivery systems. Keeping these facts in consideration, we have made an another attempt to prepare semisolid formulations containing 1% w/w of norfloxacin and metronidazole with different bases like Carbopol, polyethylene glycol, and hydroxypropylmethyl cellulose for effective treatment of bacterial infections and burn wounds. The prepared formulations were evaluated for physicochemical parameters, in vitro drug release, antimicrobial activity, and burn wound healing properties. The prepared formulations were compared with Silver Sulfadiazine cream 1%, USP. Antimicrobial activity of norfloxacin semisolid formulations was found to be equally effective against both aerobic and anaerobic bacteria in comparison to a marketed formulation of Silver Sulfadiazine 1% cream, USP. Based on the burn wound healing property, the prepared norfloxacin semisolid formulation was found to be in good agreement with marketed Silver Sulfadiazine 1% cream, USP. These findings suggest formulations containing norfloxacin and metronidazole may also prove as an effective alternative for existing remedies in the treatment of bacterial infections and burn wounds.

Full Text Available Objective : The aim was to evaluate the effect of honey dressing and silver sulfadiazene (SSD dressing on wound healing in burn patients. Materials and Methods : We retrospectively reviewed the records of 108 patients (14-68 years of age, with first and second degree burns of less than 50% of the total body surface area admitted to our institution, over a period of 5 years (2004-2008. Fifty-one patients were treated with honey dressings and 57 with SSD. Time elapsed since burn, site, percentage, degree and depth of burns, results of culture sensitivity at various time intervals, duration of healing, formation of post-treatment hypertrophic scar, and/or contracture were recorded and analyzed. Results : The average duration of healing was 18.16 and 32.68 days for the honey and SSD group, respectively. Wounds of all patients reporting within 1 h of burns became sterile with the honey dressing in less than 7 days while there was none with SSD. All wounds treated with honey became sterile within 21 days while for SSD-treated wounds, this figure was 36.5%. A complete outcome was seen in 81% of all patients in the "honey group" while in only 37% patients in the "SSD group." Conclusion : Honey dressings make the wounds sterile in less time, enhance healing, and have a better outcome in terms of hypertropic scars and postburn contractures, as compared to SSD dressings.

Many studies were carried out to improve sophisticated dressings to accelerate healing processes and reduce the microbial burden in burn wounds. This study evaluated the healing effect of herbal ointment containing extract of sesame oil, camphor and honey on second degree burn wounds in rats in comparison with daily dressing oil vaseline. Forty rats were randomly assigned to two equal groups. A deep second degree burn was formed on the back of each rat with using a standard burning technique. The burns were dressed daily with herbal ointment containing extract of sesame oil, camphor and honey in group 1, dressing oil vaseline in group 2. The response to treatment was evaluated by digital photography during the treatment on 0, 7, 14, 21, 28 days. Histological scoring was undertaken for scar tissue samples on 0, 7, 14, 21, 28 days. Considerable epithelization in the herbal ointment group vs. the control group over the study period was noted. Neovascularization was significantly higher in herbal ointment treated rats as well. In terms of difference of wound surface area, maximal healing was noticed in herbal ointment extract of sesame oil, camphor and honey group and the minimal repair in the control group. The greatest rate of healing was in the herbal ointment group containing sesame oil, camphor and honey, so the herbal ointment as a suitable substitute for dressing and healing of burn wound injuries is recommended.

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

We present a non-contact, reflective photoplethysmogram (PPG) imaging method and a prototype system for identifying the presence of dermal burn wounds during a burn debridement surgery. This system aims to provide assistance to clinicians and surgeons in the process of dermal wound management and wound triage decisions. We examined the system variables of illumination uniformity and intensity and present our findings. An LED array, a tungsten light source, and eventually high-power LED emitters were studied as illumination methods for our PPG imaging device. These three different illumination sources were tested in a controlled tissue phantom model and an animal burn model. We found that the low heat and even illumination pattern using high power LED emitters provided a substantial improvement to the collected PPG signal in our animal burn model. These improvements allow the PPG signal from different pixels to be comparable in both time-domain and frequency-domain, simplify the illumination subsystem complexity, and remove the necessity of using high dynamic range cameras. Through the burn model output comparison, such as the blood volume in animal burn data and controlled tissue phantom model, our optical improvements have led to more clinically applicable images to aid in burn assessment.

Full Text Available In this study 540 burns and wound swabs were collected from cancer patients of some Egyptian hospitals. The single infection was detected from 210, and 70 cases among wounded and burned patients, while mixed infection was 30 and 45, respectively. We recovered where 60 isolates of Pseudomonas aeruginosa, 60 isolates of Staphylococcus aureus, 7 isolates of Staphylococcus epidermidis, 4 isolates of Streptococcus pyogenes, 25 isolates of Escherichia coli, 23 isolates of Klebsiella pneumoniae and 27 isolates of Proteus vulgaris from 355 burn and surgical wound infections . All bacterial isolates showed high resistance to the commonly used β-lactams (amoxycillin, cefaclor, ampicillin, vancomycin, amoxicillin/clavulonic, and low resistance to imepenim and ciprofloxacin. Plasmid analysis of six multidrug resistant and two susceptible bacterial isolates revealed the same plasmid pattern. This indicated that R-factor is not responsible for the resistance phenomenon among the isolated opportunistic bacteria. The effect of ultraviolet radiation on the isolated bacteria was studied.

Skin wounds are associated with significant morbidity and mortality. Data are, however, not readily available for benchmarking, to allow prognostic evaluation, and to suggest when involvement of wound-healing experts is indicated. We, therefore, conducted an observational cohort study to investigate wound healing and all-cause mortality associated with different types of skin wounds. Consecutive skin wound patients who received wound care by home-care nurses from January 2010 to December 2011 in a district in Eastern Denmark were included in this study. Patients were followed until wound healing, death, or the end of follow-up on December 2012. In total, 958 consecutive patients received wound care by home-care nurses, corresponding to a 1-year prevalence of 1.2% of the total population in the district. During the study, wound healing was achieved in 511 (53.3%), whereas 90 (9.4%) died. During the first 3 weeks of therapy, healing was most likely to occur in surgical wounds (surgical vs. other wounds: adjusted hazard ratio [AHR] 2.21, 95% confidence interval 1.50-3.23), while from 3 weeks to 3 months of therapy, cancer wounds, and pressure ulcers were least likely to heal (cancer vs. other wounds: AHR 0.12, 0.03-0.50; pressure vs. other wounds: AHR 0.44, 0.27-0.74). Cancer wounds and pressure ulcers were further associated with a three times increased probability of mortality compared with other wounds (cancer vs. other wounds: AHR 3.19, 1.35-7.50; pressure vs. other wounds: AHR 2.91, 1.56-5.42). In summary, the wound type was found to be a significant predictor of healing and mortality with cancer wounds and pressure ulcers being associated with poor prognosis. © 2015 by the Wound Healing Society.

To study etiologic role of microorganisms during wound infection and elucidation of their populations interaction in patientswith burns. 2137 patients with wound infection treated in burn center were studied. 3179 samples of wound exudates and 6501 strains of microorganisms were studied. Assessment of microorganism's etiologic role was carried out using results of calculation of various statistic indexes, including indexes of ecological similarities of microorganisms in the wound (indexes of contamination, prevalence or persistence, incidence). Ecological similarity of wounds' microflora was determined by calculation of the coefficient Kj. It was established that Staphylococcus aureus is the most common cause of mono- and mixed wound infections. It was determined that Kj value for common agents points to antagonism or associative interaction. During particular time periods of the study values of Kj significantly differed and depended from species. Specifically, for Pseudomonas aeruginosa the values of Kj were equal or exceeded 30% during several years. It was the first time when correlation between persistence and ecological similarity indexes was studied in agents of wound infections. In order to reveal factors influencing on microbial etiology of mixed wound infections it is reasonable to consider the nature of interspecies interactions of causative agents.
Full Text Available Objective(s: Cucurbita moschata Duchesne (pumpkin is a well-known plant with several pharmacological effects. The aim of the present study was to assess burn wound healing activity of C. moschata peel extract (CE. Also, standardized CE was assessed for antioxidant activity and antibacterial effects against major pathogens of burns. Materials and Methods: Healing properties of topical preparation of 10% and 20% concentrations of CE were assessed on second degree burn in rats during a 14-day period as well as histological studies, total antioxidant power, lipid peroxidation and total thiol content of skin tissue samples. Results: Radical scavenging IC50 and ferric-reducing antioxidant power value were 4.015±0.20 mg/ml and 142.63±2.65 mmol Fe2+/g, respectively. Total mucilage content was 13.8%. The optimal results were obtained by 20% CE that showed 90.80±5.86 % wound closure and tissue repair as well as significant reduction of tissue oxidative stress biomarkers. Histological analyses confirmed wound healing activity of pumpkin peel extract. Conclusion: Considering the high mucilage content of the plant, providing a moist environment for wound, C. moschata peel extract could be a natural remedy for treatment of burns. Further clinical studies are suggested to confirm C. moschata peel extract as a wound healing agent.

Full Text Available Steve Gist, Iris Tio-Matos, Sharon Falzgraf, Shirley Cameron, Michael BeebeGeriatrics and Extended Care, Programs, VA Puget Sound Health Care Systems, American Lake Division, Tacoma, WA, USAAbstract: With our aging population, chronic diseases that compromise skin integrity such as diabetes, peripheral vascular disease (venous hypertension, arterial insufficiency are becoming increasingly common. Skin breakdown with ulcer and chronic wound formation is a frequent consequence of these diseases. Types of ulcers include pressure ulcers, vascular ulcers (arterial and venous hypertension, and neuropathic ulcers. Treatment of these ulcers involves recognizing the four stages of healing: coagulation, inflammation, proliferation, and maturation. Chronic wounds are frequently stalled in the inflammatory stage. Moving past the inflammation stage requires considering the bacterial burden, necrotic tissue, and moisture balance of the wound being treated. Bacterial overgrowth or infection needs to be treated with topical or systemic agents. In most cases, necrotic tissue needs to be debrided and moisture balance needs to be addressed by wetting dry tissue and drying wet tissue. Special dressings have been developed to accomplish these tasks. They include films, hydrocolloids, hydrogel dressings, foams, hydro-fibers, composite and alginate dressings.Keywords: wound care, pressure ulcers, vascular ulcers, diabetic ulcers, debridement, elderly

Increased utilization of inorganic silver as an adjunctive to many medical devices has raised concerns of emergent silver resistance in clinical bacteria. Although the molecular basis for silver resistance has been previously characterized, to date, significant phenotypic expression of these genes in clinical settings is yet to be observed. Here, we identified the first strains of clinical bacteria expressing silver resistance at a level that could significantly impact wound care and the use of silver-based dressings. Screening of 859 clinical isolates confirmed 31 harbored at least 1 silver resistance gene. Despite the presence of these genes, MIC testing revealed most of the bacteria displayed little or no increase in resistance to ionic silver (200 to 300 μM Ag(+)). However, 2 isolates (Klebsiella pneumonia and Enterobacter cloacae) were capable of robust growth at exceedingly high silver concentrations, with MIC values reaching 5,500 μM Ag(+). DNA sequencing of these two strains revealed the presence of genes homologous to known genetic determinants of heavy metal resistance. Darkening of the bacteria's pigment was observed after exposure to high silver concentrations. Scanning electron microscopy images showed the presence of silver nanoparticles embedded in the extracellular polymeric substance of both isolates. This finding suggested that the isolates may neutralize ionic silver via reduction to elemental silver. Antimicrobial testing revealed both organisms to be completely resistant to many commercially available silver-impregnated burn and wound dressings. Taken together, these findings provide the first evidence of clinical bacteria capable of expressing silver resistance at levels that could significantly impact wound management.

With the dramatic increase in the aging population, the study and care of wounds in the elderly have become priority topics for both researchers and clinicians. The effects of aging on wound healing in humans have remained controversial. The study was a 5-year epidemiological evaluation of standardized data collected regularly during patients' visits at a specialized Wound Care Center with the aim to determine the key factors influencing the healing of chronic lower extremity wounds. In this analysis of 1,158 chronic wounds, the frequency of wound closure was statistically significantly lower in older patients compared with younger patients. The share of closed wounds decreased by nearly 25% in the elderly patients (>or=70 years). The relationship between the patient's age and the proportion of wound closure was nonlinear. The effect of aging on the frequency of wound closure of chronic wounds became clinically apparent after age 60. The chronicity of the wounds was illustrated by their recurrent nature, their long duration, the presence of multiple wounds, and the frequency of concurrent infection. Comorbidity was documented by the coprevalence of up to three underlying diseases related to impaired wound healing. The present study clearly showed that aging affects chronic wound healing negatively.

Argan oil, produced from the kernels of the argan tree (Argania spinosa), has been shown to have antioxidant properties. To examine the effect of argan oil in second-degree burn wound healing, an in vivo experiment was conducted among 30 adult male Wistar rats divided into 5 equal groups: a sham group, a control group (burned but no topical agent), a group in which argan oil was applied once a day, a group in which argan oil was applied twice a day, and a group treated with 1% silver sulfadiazine once a day. Second-degree burns were created by scalding hot water (85˚ C for 15 seconds). Treatment began 24 hours after the burn injury; in the argan oil groups, 1 mL of argan oil was administered via syringe to the wound. The rate of wound healing was quantified by wound measurements on days 1, 7, and 14 after burn injury. Tissues were analyzed for molecular and histologic changes in TGF-β expression and fibroblast activity. Percent contraction of burned skin tissue was determined using the stereo investigator program, which calculated the burn field to the millimeter. Means (SD) were calculated and compared using Duncan's multiple comparison test. The group receiving argan oil twice daily showed significantly increased mRNA levels of TGF-β1 from 39.66- to 58.70-fold compared to the burn control group on day 14 (P less than 0.05). Both argan oil-treated groups showed significantly increased contraction compared to the burn control group at all 3 timepoints; the group receiving argan oil twice daily had a greater contraction rate (31% on day 7, 76% on day 14) than the silver sulfadiazine group (22% on day 7, 69% on day 14), (P less than 0.05). Histopathological assessments on days 3, 7, and 14 showed greater healing/contraction in both argan oil and silver sulfadiazine groups compared to the control group. These results suggest argan oil is effective in healing experimentally created second-degree burns in rats. Prospective, randomized, controlled clinical studies are

The floral richness of the North-East Indian region cannot be neglected in context to its medicinal importance. Achyranthes aspera Linn. (Amaranthaceae; Prickly Chaff flower) is an indigenous plant species of this region. Although the local traditional healers have ethnomedical knowledge on the use of this plant, there is no scientific study on wound-healing activity of this plant. The healing efficacy of methanol leaf extract of A. aspera (MEAA) in granulation tissue of burn wound and its antioxidant activity are investigated. Methanol extract of leaves of A. aspera was used for compounding 5% (w/w) ointment, which was applied topically twice daily in experimental burn wound in rats. Healing potential was assessed by rate of wound contraction, antioxidant and biochemical assay which was supported by gelatin zymography and histopathology. In the present study, 5% ointment of A. aspera showed significant (p < 0.05) wound healing, which was evident by wound contraction, elevation of various antioxidant enzymes viz. SOD, catalase, vitamin C and prohealing and biochemical parameters like hydroxyproline and protein content than the control animals. Up-regulated expression of matrix metalloproteinases (MMP-2 and 9) was also observed by gelatin zymography. Histopathological examination of the granulation tissues in the A. aspera-treated animals showed collagen deposition, fibroblast proliferation and formation of epidermis. The methanol leaf extract of A. aspera showed excellent wound-healing activities which has great potential for development of plant-based product.

This retrospective analysis of neonatal burn injuries was carried out at the Department of Plastic Surgery and Burn Care Centre, Pakistan Institute of Medical Sciences (PIMS), Islamabad, Pakistan. A total of 11 neonates who were aged less than 29 days were managed during the 2 year study period. Out of these, 72.7% (8) were male and 27.3% (3) were female. The mean age was 11.18±9.67days. The commonest underlying cause of burn insult was accidental direct contact with room heaters in 4 (36.3%) neonates. The TBSA burnt ranged from 3%-55%, with a mean of 18.72±17.13%. All the neonates (100%) presented during winter season. Among the body areas affected, the most common was face/head and neck (10). The commonest operative procedure undertaken among the neonates included early wound excision followed by resurfacing with split thickness autografts (5). There were three in-hospital mortalities (27.2%) in our series.

During the last two decades, a number of studies have been carried out on the application of regenerative medicine in the field of dermatology. The aim of this research was to critically review the application of regenerative medicine in the field of dermatology. The next aim was to look in depth to see whether regenerative medicine strategies have a place in the future of wound healing in a clinical setting. More specifically, to see if these strategies would apply for burns and non-healing diabetic wounds. Billions of dollars have been spent worldwide on research in wound treatment and skin regeneration. Although a high number of clinical trials show promising results, there is still no commercially available treatment for use. In addition, the outcome data from the clinical trials, taking place throughout the world, are not published in a standardized manner. Standardization within clinical trials is required for: protocols, outcome, endpoint values, and length of follow-up. The lack of standardization makes it much more difficult to compare the data collected and the different types of treatment. Despite several promising results from research and early phase clinical studies, the treatment for wounds as well as skin regeneration is still considered as an unmet clinical need. However, in the past three years, more promising research has been approaching clinical trials; this could be the solution that clinicians have been waiting for. This is a multibillion dollar industry for which there should be enough incentive for researchers and industry to seek the solution.

β-lapachone is a quinone of lapachol extracted from the bark of lapacho tree. Recent findings demonstrated that punched skin wounds of mice healed faster with β-lapachone treatment. The present study investigates the effects of β-lapachone on burn-wound skin of C57BL/6 mice injured by a 100 °C iron stick. Our results indicated that wounds treated with β-lapachone recovered faster than those treated with control ointment containing no β-lapachone. On the third day after burning, the area of β-lapachone treated-wound was 30% smaller than wound treated with control ointment. H&E and immunohistochemistry staining showed that burn-wound skin treated with ointment containing β-lapachone healed faster in its epidermis, dermis, and underlying connective tissues with more macrophages appeared than those treated with control ointment alone. RAW264.7 cell, a macrophage-like cell line derived from BALB/C mice, was used as a model for scrutinizing the effect of β-lapachone on macrophages. We found that the proliferation and the secretion of EGF and VEGF by macrophages were higher in cultures treated with β-lapachone and that ß-lapachone can also increase the release of EGF with TNF-α pretreatment. We conclude that β-lapachone plays an important role in accelerating burn wound healing, and that β-lapachone not only can raise the proliferation of macrophages but also increase the release of VEGF from macrophages.

Full Text Available The present investigation was undertaken to evaluate the healing efficacy of lyophilized aqueous leaf extract of Sea buckthorn (Hippophae rhamnoides L., family Elaeagnaceae (SBT and to explore its possible mechanism of action on experimental burn wounds in rats. The SBT extract, at various concentrations, was applied topically, twice daily for 7 days. Treatment with silver sulfadiazine (SSD ointment was used as reference control. The most effective concentration of the extract was found to be 5.0% (w/w for burn wound healing and this was further used for detailed study. The SBT-treated group showed faster reduction in wound area in comparison with control and SSD-treated groups. The topical application of SBT increased collagen synthesis and stabilization at the wound site, as evidenced by increase in hydroxyproline, hexosamine levels and up-regulated expression of collagen type-III. The histological examinations and matrix metalloproteinases (MMP-2 and -9 expression also confirmed the healing efficacy of SBT leaf extract. Furthermore, there was significant increase in levels of endogenous enzymatic and non-enzymatic antioxidants and decrease in lipid peroxide levels in SBT-treated burn wound granulation tissue. The SBT also promoted angiogenesis as evidenced by an in vitro chick chorioallantoic membrane model and in vivo up-regulated vascular endothelial growth factor (VEGF expression. The SBT leaf extract had no cytotoxic effect on BHK-21 cell line. In conclusion, SBT aqueous leaf extract possesses significant healing potential in burn wounds and has a positive influence on the different phases of wound repair.

Traumatic wounds and lacerations are common pediatric presenting complaints to emergency departments. Although there is a large body of literature on wound care, many emergency clinicians base management of wounds on theories and techniques that have been passed down over time. Therefore, controversial, conflicting, and unfounded recommendations are prevalent. This issue reviews evidence-based recommendations for wound care and management, including wound cleansing and irrigation, anxiolysis/sedation techniques, closure methods, and post-repair wound care.

Surface swab cultures have attracted attention as a potential alternative to biopsy histology or quantitative culture methods for microbiological burn wound monitoring. To our knowledge, the utility of adding a Gram-stained slide in this context has not been evaluated previously. To determine the degree of correlation of Gram stain with culture for the microbiological analysis of burn wound surfaces. Prospective laboratory analysis. Urban health region/centralized diagnostic microbiology laboratory. Burn patients hospitalized in any Calgary Health Region burn center from November 2000 to September 2001. Gram stain plus culture of burn wound surface swab specimens obtained during routine dressing changes or based on clinical signs of infection. Degree of correlation (complete, high, partial, none), including weighted kappa statistic (kappa(w)), of Gram stain with culture based on quantitative microscopy and degree of culture growth. A total of 375 specimens from 50 burn patients were evaluated. Of these, 239 were negative by culture and Gram stain, 7 were positive by Gram stain only, 89 were positive by culture only, and 40 were positive by both methods. The degree of complete, high, partial, and no correlation of Gram stain with culture was 70.9% (266/375), 1.1% (4/375), 2.4% (9/375), and 25.6% (96/375), respectively. The degree of correlation for all 375 specimens, as expressed by the weighted kappa statistic, was found to be fair (kappa(w) = 0.32).Conclusion.-The Gram stain is not suitable for the microbiological analysis of burn wound surfaces.

Objective: To explore the influence of different inner dressings in negative-pressure wound therapy (NPWT) on escharectomy wound of full-thickness burn rabbits. Methods: Eighteen Japanese white rabbits were inflicted with full-thickness burn on unilateral back. They were divided into polymer dressing group (PD), biological dressing group (BD), and silver biological dressing group (SBD), according to the random number table, with 6 rabbits in each group. On 3 days post burn, the wounds were performed with escharectomy, and then wounds of rabbits in group PD were covered with polyurethane foam. Wounds of rabbits in group BD were covered with porcine acellular dermal matrix (ADM) and wounds of rabbits in group SBD were covered with silver porcine ADM. Then continuous NPWT was performed on rabbits of the three groups for 7 days. Immediately after surgery and on post surgery day (PSD) 7, general observation of wound was conducted and tissue around the wound was harvested for determination of dry to wet weight ratio. The content of bacteria was counted and the content of tumor necrosis factor α (TNF-α), interleukin-1β (IL-1β), and IL-6 in wound was determined by enzyme-linked immunosorbent assay. Fibroblasts in wound were counted after Masson staining and number of microvessels was counted after CD31 antibody immunohistochemical staining. Data were processed with analysis of variance for repeated measurement, LSD- t test, paired samples t test, and Bonferroni correction. Results: (1) Immediately after surgery, there was no granulation tissue in basal wound of rabbits in the three groups, with rich blood supply and obvious edema. On PSD 7, much granulation tissue was found in basal wound of rabbits in the three groups, with no or mild edema and no obvious redness and swelling in wound edge. (2) There were no significant differences in dry to wet weight ratios of tissue around the wound among and within the three groups immediately after surgery and on PSD 7 (with F

Wound care is constantly evolving with the advances in medicine. Search for the ideal dressing material still continues as wound care professionals are faced with several challenges. Due to the emergence of multi-resistant organisms and a decrease in newer antibiotics, wound care professionals have revisited the ancient healing methods by using traditional and alternative medicine in wound management. People's perception towards traditional medicine has also changed and is very encouraging. The concept of moist wound healing has been well accepted and traditional medicine has also incorporated this method to fasten the healing process. Several studies using herbal and traditional medicine from different continents have been documented in wound care management. Honey has been used extensively in wound care practice with excellent results. Recent scientific evidences and clinical trials conducted using traditional and alternative medicine in wound therapy holds good promise in the future. PMID:23162243

Full Text Available The goal of this study was to determine the effect of topical Emu oil on the healing of burn wounds and hair follicle restoration in superficial II-degree burns in the skin of Balb/c mice. Thirty-two male Balb/c mice with burns on the back of the neck were divided into two groups: The Emu oil group received topical Emu oil twice daily, whereas the control was left untreated. Skin biopsies were obtained on days 4, 7, 10, and 14 of the experiment. Then the specimens were viewed with Olympus SZX research microscope. The Emu oil treated burns were found to heal more slowly and inflammation lasted longer in this group. The number of hair follicles in the margins of the wounds increased through time in the Emu oil group compared to the control group. Also, the hair follicles in the Emu oil group were in several layers and seemed to be more active and mature. Moreover, Emu oil had a positive effect on fibrogenesis and synthesis of collagen. The findings indicate that although Emu oil delays the healing process, it has a positive effect on wound healing and it increases the number of hair follicles in the margins of the wound.

Full Text Available Medicines of biogenic origin with micro-organic, regenerative and analgesic properties are becoming more and more significant in the treatment of burn wounds. These properties are found in apitherapeutics such as propolis and honey—products collected and processed by a honey bee. Their effect on the course of the healing processes is multidirectional. The aim of the study was a histopathological and biochemical analysis of the processes of scar formation in experimentally evoked burn wounds in white pigs treated with the 1% and 3% Sepropol balms containing standardized extracts of propolis and honey. The results were compared with the therapeutic effects obtained with dermazin cream (1% silver sulfadiazine. The level of collagen was determined in the wounds treated with 1% and 3% Sepropol and compared with the collagen level in healthy skin and wounds treated with dermazin. Granulation and regenerated epithelium formation times were compared, with the 3% Sepropol being by far the most effective. The 3% Sepropol also increased the collagen level to 116% with the control sub-groups scoring between 80% and 98%. The results show the healing process of burn wounds in pigs treated with the Sepropol balm starts earlier and has a faster course than the standard dermazin therapy.

This study assessed the effect of early vs delayed postburn wound excision and skin grafting on the in vivo neutrophil delivery to a delayed-type hypersensitivity (DTH) reaction and a bacterial skin lesion (BSL). Male Lewis rats were presensitized to keyhole-limpet hemocyanin. Group 1 comprised sham controls. Groups 2 through 4 were given a 30% 3 degrees scald burn, but the burn wounds were excised, and skin was grafted on days 1, 3, and 7, respectively, after the burn. Group 5 comprised burn controls. Twelve days after burn trauma, all rats were injected at different intervals (during a 24-hour period) with a trio of intradermal injections of keyhole-limpet hemocyanin, Staphylococcus aureus 502A, and saline at different sites. In vivo neutrophil delivery to these dermal lesions was determined by injecting indium in 111 oxyquinoline-labeled neutrophils isolated from similarly treated groups of rats. Neutrophil delivery to DTH and BSL lesions was restored to normal by excision and skin grafting of the burn wound one day after burn trauma. Waiting three days after burn trauma to excise and skin graft the wound partially, but not completely, restored the in vivo neutrophil delivery to DTH and BSL lesions. Waiting one week to excise and skin graft a burn wound resulted in no improvement in neutrophil delivery to DTH and BSL dermal lesions. It was concluded that burn wound excision and skin grafting immediately after burn trauma restored in vivo neutrophil delivery to a BSL and DTH dermal lesion. This may, in part, explain the beneficial effect of early aggressive burn wound debridement in patients with burn injuries

The disease is common in rural tropical communities in West and Central Africa, where access to proper health care is limited. Pathogenesis of the characteristic painless ulcers is linked to the elaboration by M. ulcerans of a lipid toxin called mycolactone that has potent cytopathic, immunosuppressive, and analgesic effects on a host of cells in cutaneous tissues. Mycolactone is known to profoundly inhibit secretion of a plethora of proteins that are essential for wound healing. Even though a combination antibacterial therapy of streptomycin and rifampicin for 8 weeks is effective for treatment, it relies on good and appropriate wound management to prevent secondary bacterial infections and improve healing. Evidence-based interventions for wound care in Buruli ulcer disease are often lacking and have relied on expert advice and recommendations. Surgical interventions are limited to debridement of necrotic tissue and grafting of extensive ulcers, usually after antibiotic therapy. Patients’ rehabilitation is an important component of care to reduce disabilities associated with the disease and proper integration into the community after treatment.

Most of the skin disorders that occur in neonatal intensive care units are due in part to the immaturity and vulnerability of the neonatal skin. Various iatrogenic diagnostic and therapeutic procedures are also conducive to iatrogenic damage. This study was to review the neonates admitted to our neonatal intensive care unit who needed wound management, and to assess the most common skin injuries and wounds, and their aetiology. Data were extracted from medical records of neonates who needed wound management in our Neonatal Intensive Care Unit between January 31, 2012 and January 31, 2013. Information about gestational age, sex, birth weight, area of involvement, wound aetiology, and therapy were collected. Among the 211 neonates observed, wound management was required in 10 cases of diaper dermatitis, 7 epidermal stripping, 6 extravasation injuries, 5 pressure ulcers, 1 surgical wound and infection, 1 thermal burn, and 5 other lesions. International guidelines in neonatal wound care practice are not available, and further research concerns are clearly needed. Dressings and antiseptic agents should be chosen with great care for application to neonates, with particular attention to the prevention of adverse events in this sensitive population. Team work among dermatologists, neonatologists and nurses is crucial for the successful treatment of neonates.

This research was aimed to find the skin irritation and burns treatment effect of wound dressing with mi- crospheres containing levofloxacin. We used reference GB/T16886. 10-2005 to evaluate the dressing skin irritation. We prepared rabbit models divided into three groups. The control group was rapped with Vaseline gauze bandage, while the positive control group was rapped with the wounds of nano-silver paste bandage. The experimental sample group was rapped with wound dressing with microspheres containing levofloxacin. We measured the wound without healing area and the hydroxyproline content at the ends of 3 d, 6 d, 9 d, 14 d, 21 d, 28 d. and meanwhile performed histopathological examination. The experimental results showed that the dressing primary irritation index was 0. The nonhealing wound area of theexperimental sample group and positive control group at the ends of 6 d, 9 d, 14 d, 21 d were less than that of the control group (Pdressing with microspheres containing levofloxacin has minimal skin irritation, effectively promote wound healing of burn.

While use of biocomposite temporary dressings in burn wounds is common practice, the complex anatomic structures of the hand make this treatment option challenging. For this reason, the Biobrane ((R)) Glove (Smith&Nephew) has been developed. However, limited information regarding burn treatment with Biobrane ((R)) Gloves can be found in the literature. Functional and cosmetic outcomes of 13 second degree burn wounds of the hand in 10 patients treated with Biobrane ((R)) Gloves were evaluated using the Vancouver scar scale (VSS) and the DASH-score (disabilities of the arm, shoulder and hand). We evaluated wound healing times and questioned patients about pain related to Biobrane ((R)) Glove treatment in comparison to conventionally managed second degree burn wounds in other parts of the body and about acceptance of Biobrane ((R)) Glove treatment. In addition, we estimated the costs for use and wound management time for both Biobrane ((R)) Glove treatment and conventional wound management for 14 days. Burn wounds treated with Biobrane ((R)) Gloves had excellent functional and cosmetic outcomes [DASH score median of 0 (min. 0; max. 3.33) and VSS median of 3 (min. 0; max. 5)]. Wound healing times were lower (mean 9 days). According to patients' response to overall acceptance, 90% responded as being "very satisfied" with Biobrane ((R)) Glove treatment and 75% responded that Biobrane ((R)) Glove treatment was "much less painful" compared to conventional burn management. The material costs of the Biobrane ((R)) Glove treatment, over 14 days, were approx. double compared to conventional wound management costs. In contrast, the time required for conventional wound management over 14 days was four times longer than for treatment with Biobrane ((R)) Gloves. Thus, taking personnel expenses into consideration, total costs of Biobrane ((R)) Glove treatment are comparable to those of conventional wound management. Biobrane ((R)) Glove treatment of hand burns resulted in excellent

To evaluate a calculating method of wound water loss (WWL) in hospitalized burn patients. Eighty-five adult burn patients with total burn area over 50% were enrolled in the study. The WWL formula after shock stage (after 3rd postburn day) was given as: WWL (ml/%/kg/24 h) = [input (ml/24 h)-urine output (ml/24 h)-500 ml] / actual burn wound area(%) / body weight (kg). The result was compared with that determined by other formulas such as Davies, S.M.S.P and Lamke and palm rule. The calculated daily WWL in burn patients after shock stage was found out to be 0.9 +/- 0.1 ml/%/kg/24 h by this method. This figure is comparable with that calculated by several different methods. Palm rule could be simply applied in the patients with body weight around 60 kg. This method and palm rule were proved to be simple and practical for the calculation of WWL in burn patients, which could be applied in clinical work.
Full Text Available Background: Infection is an important cause of mortality in burns. Rapidly emerging nosocomial pathogens and the problem of multi-drug resistance necessitates periodic review of isolation patterns and antibiogram in the burn ward. Aim: Keeping this in mind, the present retrospective study from wounds of patients admitted to burns unit was undertaken to determine the bacteriological profile and the resistance pattern from the burn ward over a period of three years (June 2002 to May 2005 and was compared with the results obtained during the previous five years (June 1997-May 2002, to ascertain any change in the bacteriological profile and antimicrobial resistance pattern. Materials and Methods: Bacterial isolates from 268 wound swabs taken from burn patients were identified by conventional biochemical methods and antimicrobial susceptibility was performed. Statistical comparison of bacterial isolates and their resistance pattern with previous five years data was done using c2 test. Results and Conclusions: During the period from 2002 to 2005 Pseudomonas species was the commonest pathogen isolated (51.5% followed by Acinetobacter species (14.28%, Staph. aureus (11.15%, Klebsiella species (9.23% and Proteus species (2.3%. When compared with the results of the previous five years i.e., 1997 to 2002, Pseudomonas species was still the commonest pathogen in the burns unit. However, the isolation of this organism and other gram-negative organisms had decreased in comparison to previous years. Newer drugs were found to be effective.
Full Text Available Objective : Biological dressings like collagen are impermeable to bacteria, and create the most physiological interface between the wound surface and the environment. Collagen dressings have other advantages over conventional dressings in terms of ease of application and being natural, non-immunogenic, non-pyrogenic, hypo-allergenic, and pain-free. This study aims to compare the efficacy of collagen dressing in treating burn and chronic wounds with that of conventional dressing materials. Materials and Methods : The records of 120 patients with chronic wounds of varied aetiologies and with mean age 43.7 years were collected and analyzed. The patients had been treated either with collagen or other conventional dressing materials including silver sulfadiazine, nadifloxacin, povidone iodine, or honey (traditional dressing material. Patients with co-morbidities that could grossly affect the wound healing like uncontrolled diabetes mellitus, chronic liver or renal disease, or major nutritional deprivation were not included. For the purpose of comparison the patients were divided into two groups; ′Collagen group′ and ′Conventional group′, each having 60 patients. For assessment the wound characteristics (size, edge, floor, slough, granulation tissue, and wound swab or pus culture sensitivity results were recorded. With start of treatment, appearance of granulation tissue, completeness of healing, need for skin grafting, and patients′ satisfaction was noted for each patient in both groups. Results : With two weeks of treatment, 60% of the ′collagen group′ wounds and only 42% of the ′conventional group′ wounds were sterile (P=0.03. Healthy granulation tissue appeared earlier over collagen-dressed wounds than over conventionally treated wounds (P=0.03. After eight weeks, 52 (87% of ′collagen group′ wounds and 48 (80% of ′conventional group′ wounds were >75% healed (P=0.21. Eight patients in the ′collagen group′ and 12 in the

Wound care is a classic example of a surgical realm with a great variation in care. The diversity in wounds and wound treatments, the limited amount of convincing evidence, and the diverging opinions among doctors and nurses involved in wound care contribute to this undesirable variation in care. For chronic wounds, such as arterial or venous ulcers, pressure sores, and diabetic foot ulcers, but also for acute wounds after surgery or trauma, international and national guidelines provide recommendations on diagnostic procedures and treatment options, but rely mostly on expert opinion. We present the available evidence from Cochrane systematic reviews for the systemic treatment (i.e., not prevention) of patients with wounds, as opposed to topical wound treatments. This evidence shows: - Venous ulcers: High-compression therapy is the classic and evidence-based treatment for treating venous ulcers. Oral pentoxifylline promotes ulcer healing with and without compression therapy. Oral zinc is not effective to heal venous ulcers. - Acute wounds: Recombinant human growth hormone accelerates healing of large burn wounds and donor sites, while high-carbohydrate feeding might reduce the risk of pneumonia. Linezolid is more effective than vancomycin for treating skin and soft tissue infections. Hyperbaric oxygen may help heal crush wounds and skin grafts. Therapeutic touch does not heal acute wounds. - Pressure sores: Air-fluidized and some low-tech devices appear effective for treating existing pressure ulcers. Oral zinc, protein, or vitamin C supplements seem ineffective. Also, evidence is lacking on the effectiveness of repositioning regimes as a treatment option. - Diabetic ulcers: Hyperbaric oxygen therapy and pressure-relieving devices may improve healing rates. - Arterial ulcers: Prostanoids and spinal cord stimulation may be effective in healing ischemic ulcers. Thus, fortunately, some high-level evidence exists for various local and systemic interventions in wound

Full Text Available Current wound assessment practices are lacking on several measures. For example, the most common method for measuring wound size is using a ruler, which has been demonstrated to be crude and inaccurate. An increase in periwound temperature is a classic sign of infection but skin temperature is not always measured during wound assessments. To address this, we have developed a smartphone application that enables non-contact wound surface area and temperature measurements. Here we evaluate the inter-rater reliability and accuracy of this novel point-of-care wound assessment tool.The wounds of 87 patients were measured using the Swift Wound app and a ruler. The skin surface temperature of 37 patients was also measured using an infrared FLIR™ camera integrated with the Swift Wound app and using the clinically accepted reference thermometer Exergen DermaTemp 1001. Accuracy measurements were determined by assessing differences in surface area measurements of 15 plastic wounds between a digital planimeter of known accuracy and the Swift Wound app. To evaluate the impact of training on the reproducibility of the Swift Wound app measurements, three novice raters with no wound care training, measured the length, width and area of 12 plastic model wounds using the app. High inter-rater reliabilities (ICC = 0.97-1.00 and high accuracies were obtained using the Swift Wound app across raters of different levels of training in wound care. The ruler method also yielded reliable wound measurements (ICC = 0.92-0.97, albeit lower than that of the Swift Wound app. Furthermore, there was no statistical difference between the temperature differences measured using the infrared camera and the clinically tested reference thermometer.The Swift Wound app provides highly reliable and accurate wound measurements. The FLIR™ infrared camera integrated into the Swift Wound app provides skin temperature readings equivalent to the clinically tested reference thermometer

In an attempt for better treatment of bacterial infections and burn wounds, plaster formulations containing different concentrations of norfloxacin were prepared using polymers like polyvinylpyrrolidone and polyvinyl alcohol and evaluated for physicochemical parameters, in vitro drug release, antimicrobial activity, and burn wound healing properties. The prepared formulations were compared with silver sulfadiazine cream 1%, USP. Plaster formulations containing different concentrations of norfloxacin were prepared by solvent casting method using combination of polymers like polyvinylpyrrolidone and polyvinyl alcohol. These plasters were characterized for drug content, thickness, percentage elongation, tensile strength, in vitro drug release properties, and antimicrobial activity against various strains of aerobic and anaerobic microorganisms. The wound healing property was evaluated by histopathological examination and by measuring the wound contraction. The in vitro release and in vitro skin permeation followed the first-order kinetics followed by diffusion as dominant release mechanism. In spite of the significant antimicrobial and wound healing effects produced by plasters, the observed values were less than the values obtained with silver sulfadiazine 1% cream (P norfloxacin transdermal plasters could be employed as an alternative to commercial silver sulfadiazine 1% cream.

Selecting a suitable wound dressing for patients with partial-thickness burns (PTBs) is important in wound care. However, the comparative effectiveness of different dressings has not been studied. We report the protocol of a network meta-analysis designed to combine direct and indirect evidence of wound dressings in the management of PTB. We will search for randomised controlled trials (RCTs) evaluating the wound-healing effect of a wound dressing in the management of PTB. Searches will be conducted in MEDLINE, EMBASE, the Cochrane Central Register of Controlled Trials, the Cochrane Wounds Group Specialised Register and CINAHL. A comprehensive search strategy is developed to retrieve articles reporting potentially eligible RCTs. Besides, we will contact the experts in the field and review the conference proceedings to locate non-published studies. The reference lists of articles will be reviewed for any candidate studies. Two independent reviewers will screen titles and abstracts of the candidate articles. All eligible RCTs will be obtained in full text to perform a review. Disagreement on eligibility of an RCT will be solved by group discussion. The information of participants, interventions, comparisons and outcomes from included RCTs will be recorded and summarised. The primary outcome is time to complete wound healing. Secondary outcomes include the proportion of burns completely healed at the end of treatment, change in wound surface area at the end of treatment, incidence of adverse events, etc. The result of this review will provide evidence for the comparative effectiveness of different wound dressings in the management of PTB. It will also facilitate decision-making in choosing a suitable wound dressing. We will disseminate the review through a peer-review journal and conference abstracts or posters.

Several herbal remedies have been used as topical agents to cure burn wound, one of the most common injuries in worldwide. In this study, we investigated the potential use of Cleistocalyx operculatus essential oil to treat the burn wound. We identified a total of 13 bioactive compounds of essential oil, several of which exhibited the anti-inflammatory and antimicrobial activities. Furthermore, the essential oil showed the antibacterial effect against S. aureus but not with P. aeruginosa. The supportive effect of essential oil on burn wound healing process also has been proven. Among three groups of mice, wound contraction rate of essential oil treated group (100%) was significantly higher than tamanu oil treated (79%) and control mice (71%) after 20 days (0.22 ± 0.03 versus 0.31 ± 0.02 cm 2 , resp., p essential oil formed a complete epidermal structure, thick and neatly arranged fibers, and scattered immune cells in burn wound. On the contrary, saline treated burn wound formed uneven epidermal layer with necrotic ulcer, infiltration of immune cells, and existence of granulation tissue. This finding demonstrated Cleistocalyx operculatus essential oil as promising topical dermatological agent to treat burn wound.

Background - The growing prevalence and incidence of nonhealing acute and chronic wounds is a worrying concern. A major challenge is the lack of united services aimed at addressing the complex needs of individuals with wounds. However, the WHO argues that interprofessional collaboration in education and practice is key to providing the best patient care, enhancing clinical and health-related outcomes and strengthening the health system. It is based on this background that the team approach to wound care project was conceptualised. The project was jointly initiated and realised by the Association for the Advancement of Wound Care (AAWC-USA), the Australian Wound Management Association (AWMA) and the European Wound Management Association (EWMA). Aim - The aim of this project was to develop a universal model for the adoption of a team approach to wound care. Objective The overarching objective of this project was to provide recommendations for implementing a team approach to wound care within all clinical settings and through this to develop a model for advocating the team approach toward decision makers in national government levels. Method An integrative literature review was conducted. Using this knowledge, the authors arrived at a consensus on the most appropriate model to adopt and realise a team approach to wound care. Results - Eighty four articles met the inclusion criteria. Following data extraction, it was evident that none of the articles provided a definition for the terms multidisciplinary, interdisciplinary or transdisciplinary in the context of wound care. Given this lack of clarity within the wound care literature, the authors have here developed a Universal Model for the Team Approach to Wound Care to fill this gap in our current understanding. Conclusion - We advocate that the patient should be at the heart of all decision-making, as working with the Universal Model for the Team Approach to Wound Care begins with the needs of the patient.

Although deep wounds are usually treated by flap transfers, the operation is invasive and associates with serious complications. Skin grafts may be a less invasive means of covering wounds. However, skin grafts cannot survive on deep defects unless high-quality granulation tissue can first be generated in the defects. Technologies that generate high-quality granulation tissue are needed. One possibility is to use wound care matrices, which are bioengineered skin and soft tissue substitutes. Because they all support the healing process by providing a premade extracellular matrix material, these matrices can be termed “extracellular matrix replacement therapies”. The matrix promotes wound healing by acting as a scaffold for regeneration, attracting host cytokines to the wound, stimulating wound epithelialization and angiogenesis, and providing the wound bed with bioactive components. This therapy has lasting benefits as it not only helps large skin defects to be closed with thin skin grafts or patch grafts but also restores cosmetic appearance and proper function. In particular, since it acts as a layer that slides over the subcutaneous fascia, it provides skin elasticity, tear resistance, and texture. Several therapies and products employing wound care matrices for wound management have been developed recently. Some of these can be applied in combination with negative pressure wound therapy or beneficial materials that promote wound healing and can be incorporated into the matrix. To date, the clinical studies on these approaches suggest that wound care matrices promote spontaneous wound healing or can be used to facilitate skin grafting, thereby avoiding the need to use
Full Text Available Healing of burn tissue is a complete process involving reepitelization, granulation tissue formation and extracellular matrix remodeling. Thermal injury produces profound systemic changes, such as oligemic shock, anemia, renal failure and metabolic disorders. This causes direct tissue damages: inflammation and infection reactions. The tissue lesion also leads to increased oxidative stress in cells, as it has been observed by the low activity of endogenous antioxidant enzymatic and nonenzymatic systems. In this context, tissue matrix metalloproteinases (MMP plays a key role in normal physiology of conjunctive tissue during its development, morphogenesis or wound healing, having an irregular activity and being involved in the patho-physiological processes. The analysis of biological samples, MMP profiles contribute to the characterization of some processes involving tissue remodeling, processes related to wound or burn healing, possibly to the development of new therapies. In this context we studied the proliferative effect of levan, a polysaccharide produced by Gram negative bacteria, Zymomonas mobilis, a microorganism that plays an important role in modern biotechnology to produce substances of great interest in biotechnology, food industry or in biomedicine. Our studies focused on analysis of tissue MMPs profiles from Wistar rats with lesions caused by mechanic processes on skin (wounds and thermal (burn, treated by hallotherapy inCacica and Dej salt mines, before and after the treatment with levan. The results indicate that levan, a natural polysaccharide produced by wild type Z. mobilis NCIB 11163, as well as other bacterial strains, seems to have real value in the management of wounds and burns, applied individually or in combination with natural or artificial haloteraphy. The way that levan participates in the healing process is unknown, probably by activating the tissue metalloproteinases.

Sepsis is a leading cause of death among severely burned patients. Burn injury disrupts the protective skin barrier and causes immunological dysfunction. In our previous studies, we found that burn injury and wound infection causes a significant decline in lymphocyte populations, implying adaptive immune system dysfunction. In the present study, we examined the effect of treatment with Fms-like tyrosine kinase-3 Ligand (Flt3L) on T cell phenotype and function in a model of burn wound sepsis. FLt3L is an essential cytokine required for hematopoietic progenitor cell development and expansion of both myeloid and lymphoid lineages. Flt3L has been shown to potentiate innate immune functions of dendritic cells and neutrophils during burn wound sepsis. However, the ability of Flt3L to improve T cell function during burn wound sepsis has not been previously evaluated. Mice underwent 35% total body surface area scald burn and were treated with Flt3L (10 μg) or vehicle daily via the intraperitoneal route starting 1 day after burn injury. On day 4 after burn injury, Pseudomonas aeruginosa was used to induce wound infection. Leukocytes in spleen and wound draining lymph nodes were characterized using flow cytometry. Bacterial clearance, organ injury, and survival were also assessed. Flt3L treatment prevented the decline in splenic CD4 and CD8 T cells caused by burn injury and infection. Flt3L treatment also attenuated the decline in CD28 expression on CD4 and CD8 T cells and IFNγ production by CD8 T cells in the spleen and wound draining lymph nodes. Furthermore, Flt3L decreased the levels of programmed death ligand 1 expression on splenic dendritic cells and macrophages. Flt3 treatment improved systemic bacterial clearance, decreased liver and kidney injury, and significantly improved survival in mice with burn wound sepsis. Burn injury and associated sepsis causes significant loss of T cells and evidence of T cell dysfunction. Flt3L attenuates T cell dysfunction and

Care for patients with chronic wounds can be complex, and the chances of poor outcomes are high if wound care is not optimized through evidence-based protocols. Tracking and managing every variable and comorbidity in patients with wounds is difficult despite the increasing use of wound-specific electronic medical records. Harnessing the power of big data analytics to help nurses and physicians provide optimized care based on the care provided to millions of patients can result in better outcomes. Numerous applications of machine learning toward workflow improvements, inpatient monitoring, outpatient communication, and hospital operations can improve overall efficiency and efficacy of care delivery in and out of the hospital, while reducing adverse events and complications. This article provides an overview of the application of big data analytics and machine learning in health care, highlights important recent advances, and discusses how these technologies may revolutionize advanced wound care. © AORN, Inc, 2018.

Burn wound is a global problem affecting millions of people. It is the major cause of mortality and morbidity. This study was aimed to isolate and identify the wound isolates by 16S rRNA and to assess their susceptibility to antibiotics and silver nanoparticles. Silver nanoparticles were synthesized using aqueous extract of A.indica. The silver nanoparticles were characterized by FESEM, XRD, FTIR and DSC. Antibacterial susceptibility of the isolates was assessed by well diffusion method. The wound isolates were identified as S.aureus and E.coli. Both isolates were resistant to β lactum antibiotics, aminoglycoside, quinolones and macrolides. The inhibition zone exhibited by all antibiotics against both organisms was less than 5 mm. The size of silver nanoparticles were recorded as 55 nm. XRD confirmed the crystalline nature of the nanoparticles. TGA and DSC of silver nanoparticles showed the loss of weight and the melting point of silver nanoparticles was recorded at 871.3°C. Silver nano particles inhibited S.aureus and E.coli with an inhibition zone of 27 mm and 32 mm respectively. Therefore the study demonstrated that only silver containing dressings can be used in burn wounds infected by multi drug resistant super bugs.

Telemedicine is increasingly applied in developed settings to facilitate transfer of information to and from burn surgeons across vast geographic areas. WhatsApp is a widely available and extremely user-friendly encrypted smartphone application that does not require the expensive physical and personnel infrastructure that characterizes many of these telemedicine systems. The aim of this study was to review the use of WhatsApp to facilitate paediatric burn injury consultations to a regional burn centre in a developing country, where burn care continues to be thwarted by administrative apathy, poor resource allocation and lack of attention to medical and nursing education at all levels. A retrospective review was undertaken of all consultations using WhatsApp over an 18-month period, received by the burn centre's two senior medical practitioners. The specific origin and nature of the telemedicine requests for advice, transfer or follow-up were collected, as were data relating to the demographics of the patients, the aetiology, mechanism and extent of the burn injury. The impact of the system of communication in terms of reductions in admissions and clinic visits was assessed, and a cost analysis was undertaken. Feedback was also obtained from those health practitioners regularly using the service. 838 communications occurred during the study period, which included 1562 distinct clinical queries. 486 interactions (58%) originated from within the hospital, the majority of which were initiated by surgeons in training or burn nurse practitioners. 352 (42%) consultations were from outside the hospital. Queries related to the full spectrum of burn care, including emergency management and stabilization, triage and transfer, the need for escharotomy, fluid resuscitation, wound care, the timing and nature of surgical intervention, as well as follow-up and rehabilitation. While no significant changes in the number of surgical interventions or admissions were observed when

The modified Meek micrografting technique constitutes a rapid and efficient surgical approach for the skin coverage of extensive full-thickness burn injuries. A total of 10 burn patients (mean 68 ± 9.2% TBSA) admitted to our burn unit required one or more Meek micrografting procedures (mean 2.2 ± 0.5) to cover in average 43.4 ± 11.6% TBSA (range between 10 and 75% TBSA). This goal was achieved using a donor site area ranging between 2.5 and 18% TBSA. All patients developed local infection to Pseudomona aeruginosa (75%), Stenotrophomona maltophilia (25%), methicillin-resistant Staphylococcus aureus (12.5%), and Acinetobacter baumannii (12.5%). Thus, the average of Meek regrafting after graft-take failure was 13.1 ± 6.4% TBSA (median: 9%; range from 0 to 36%). The period to obtain stable definitive wound closure was in average of 67.2 ± 21 days post injury. The modified Meek micrografting provides a reliable and versatile method for the coverage of large burn wounds with limited autograft donor sites and is now routinely used in our institution. Its systematic use improves operating times and overall outcomes reducing the number of surgeries, increasing the percentage of graft take, and decreasing the length of stay.

Small burns are common and can cause disproportionate levels of disability. The ability to measure muscle impairment and consequent functional disability is a necessity during rehabilitation of patients. This study aimed to determine the reliability and validity of grip and muscle strength dynamometry in patients with unhealed, minor burn wounds. Grip and muscle strength were assessed three times on each side. Assessment occurred at presentation for the initial injury and again every other day (or every 5 days beyond 10 days post injury) until discharge from the service. Reliability was assessed using intraclass correlation. Minimum detectable differences were calculated for each muscle group. Validity was assessed using regression analysis, incorporating appropriate burn severity measures and patient demographics. Thirty patients with TBSA ≤15% were assessed. Both grip and muscle strength demonstrated very good reliability (intraclass correlation coefficient: 0.85-0.96). Minimum detectable differences ranged from 3.8 to 8.0 kg. Validity of both forms of dynamometry was confirmed through associations with gender for all muscle groups (P dynamometry are reliable and valid assessments of strength and are applicable for clinical use in patients who have unhealed, minor burn wounds.

Objective: To explore the clinical effects of repair of wounds in the fingers after electrical burn with wrist perforator free flaps. Methods: Twelve patients (13 fingers) with electrical burn were hospitalized in our burn ward from January 2016 to January 2017. After radical debridement, the size of wounds ranged from 5.0 cm×2.0 cm to 10.0 cm×7.0 cm. Wounds with size below or equal to 6.0 cm ×2.5 cm were repaired with free flaps based on the superficial palmar branch of radial artery, with flap area ranging from 2.5 cm×2.2 cm to 6.0 cm×4.5 cm. The superficial palmar branch of radial artery, subcutaneous vein, and palmar cutaneous branch of the median nerve underwent end-to-end anastomosis with digital proper artery, dorsal superficial vein, and digital proper nerve in the finger, respectively. The donor sites were sutured directly. Wounds with size larger than 6.0 cm×2.5 cm were repaired with free flaps based on the dorsal carpal branch of ulnar artery, with flap area ranging from 4.5 cm×3.0 cm to 12.0 cm×8.5 cm. The dorsal carpal branch of ulnar artery, subcutaneous vein, and medial antebrachial cutaneous nerve underwent end-to-end anastomosis with digital proper artery, dorsal superficial vein, and digital proper nerve in the finger, respectively. The donor sites were sutured directly or covered by full-thickness skin graft from abdomen. Results: Five free flaps based on the superficial palmar branch of radial artery and 8 free flaps based on the dorsal carpal branch of ulnar artery were used in the patients. In one week after surgery, 12 flaps survived completely, while one free flap based on the dorsal carpal branch of ulnar artery suffered from slight infection, after depressing change, it survived in the end. After the follow-up of half a year, the flaps were full in shape and the distance of two-point discrimination of ranged from 4.0 to 7.0 mm. The fingers showed good functional recovery and no deformity. The grade of function of the fingers was

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. Copyright © 2013 Elsevier Ireland Ltd. All rights reserved.

Cornea is an avascular transparent tissue. Ocular trauma caused by a corneal alkali burn induces corneal neovascularization (CNV), inflammation, and fibrosis, leading to vision loss. The purpose of this study was to examine the effects of Zerumbone (ZER) on corneal wound healing caused by alkali burns in mice. CNV was induced by alkali-burn injury in BALB/C female mice. Topical ZER (three times per day, 3μl each time, at concentrations of 5, 15, and 30μM) was applied to treat alkali-burned mouse corneas for 14 consecutive days. Histopathologically, ZER treatment suppressed alkali burn-induced CNV and decreased corneal epithelial defects induced by alkali burns. Corneal tissue treated with ZER showed reduced mRNA levels of pro-angiogenic genes, including vascular endothelial growth factor, matrix metalloproteinase-2 and 9, and pro-fibrotic factors such as alpha smooth muscle actin and transforming growth factor-1 and 2. Immunohistochemical analysis demonstrated that the infiltration of F4/80 and/or CCR2 positive cells was significantly decreased in ZER-treated corneas. ZER markedly inhibited the mRNA and protein levels of monocyte chemoattractant protein-1 (MCP-1) in human corneal fibroblasts and murine peritoneal macrophages. Immunoblot analysis revealed that ZER decreased the activation of signal transducer and activator of transcription 3 (STAT3), with consequent reduction of MCP-1 production by these cells. In conclusion, topical administration of ZER accelerated corneal wound healing by inhibition of STAT3 and MCP-1 production. Copyright © 2017. Published by Elsevier B.V.

This paper reports the characteristics and local management of 826 acute wounds identified during an audit across all health care providers serving the population of Bradford, UK. Of the wounds encountered 303 were traumatic wounds and 237 primary closures with smaller numbers of other acute wound types. Of the 303 traumatic wounds 174 occurred in women (57.4%). Men predominated in the under 45s (65M:26F), this being largely accounted for by hand and finger trauma (n = 62) particularly in patients of working age (M32:F12). Women predominated in the over 65s (50M:130F), this being largely accounted for by lower limb traumatic wounds (M24:F91), the majority of these being in patients 65 and over (M14:F82). In this sub-group of 96 patients 25 had wounds of 6 weeks or longer duration, only 3 had undergone Doppler assessment and only 2 received compression bandaging. Typically these wounds were of recent origin and small in size (under 1 week and less than 5 cm2 in surface area) however exceptions occurred where 10 people had wounds over 25 cm2 in area while 3 wounds had been present for over 5 years. 101 (12.2%) of the encountered wounds were considered to be infected although the practice of wound swabbing in the presence of presumed infection seemed inadequate with 37.6% of all infected acute wounds not being swabbed while 97 non-infected wounds were swabbed. Where wounds were swabbed 4.5% were found to be MRSA positive. Across all acute wound types (with the sole exception of primary closures) antimicrobial wound dressings were the most prevalent form of dressing and covered 56 (55.4%) of all infected wounds.
Full Text Available Background This study aimed to assess the effects of the topical application of tamoxifen on wound healing of burned skin in Wistar rats by evaluating 3 healing characteristics: fibrotic tissue thickness (FTT, scar surface area (SSA, and angiogenesis in the healed scar tissue. Methods Eighteen male Wistar rats were used in this study. A third-degree burn wound was made on the shaved animals’ back, measuring 2×2×2 cm. In the first group, a 2% tamoxifen ointment was applied to the wound twice daily for 8 weeks. The second group received a placebo ointment during the same period. The third group did not receive any treatment and served as the control group. Results The median (interquartile range=[Q1, Q3] FTT was 1.35 (1.15, 1.62 mm, 1.00 (0.95, 1.02 mm, and 1.25 (0.8, 1.5 mm in the control, tamoxifen, and placebo groups, respectively (P=0.069. However, the FTT in the tamoxifen group was less than in the placebo and control groups. The median angiogenesis was 3.5 (3.00, 6.25, 8.00 (6.75, 9.25, and 7.00 (5.50, 8.25 vessels per high-power field for the control, tamoxifen, and placebo groups, respectively (P=0.067. However, the median angiogenesis was higher in the tamoxifen group than in the control group. No significant difference was observed in the mean SSA between the tamoxifen group and the control group (P=0.990. Conclusions Local application of tamoxifen increased angiogenesis and decreased the FTT, with no change in the SSA in burned skin areas. These effects are expected to expedite the wound healing process, reducing contracture and preventing hypertrophic scar and keloid formation.

The author presents a case report of an elderly patient who was extremely frail and debilitated. The patient was a resident of a skilled care facility because of advanced chronic illnesses that included end-stage Alzheimer, dementia, and Parkinson disease. This patient had acquired multiple stages III to IV pressure ulcers. Aggressive wound care treatment was initiated with partial success, but the patient passed away before the wound could completely heal. Medical literature was reviewed to offer the best possible wound care approach in providing care to patients who are terminally ill without compromising the patient's dignity and comfort and at the same time delivering cost-effective quality care.

Burn injury survival means coping with more than just the physical changes and disabilities often encountered after burn injury. Overall quality of life is important, and issues such as sexuality and intimacy are significant facets of quality of life. A literature review revealed limited research regarding current burn center practices related to sexuality and intimacy concerns of burn survivors and their partners. A 28-item survey, designed by seasoned burn care professionals and survivors, was distributed to burn care practitioners attending general sessions at several burn conferences in the United States. Seventy-one (86%) of the invited respondents completed the survey, with nursing representing the majority (63%). Mean tenure working in burn care was 10 years. Mean age of respondents was 40.5 years, with 75% being female and 25% male. Nearly half (47%) reported that specific staff was not designated to discuss sexuality and intimacy with survivors in their center. Sixty-two percent reported that special training regarding sexuality and intimacy was not available at their burn center. Only 14% of respondents indicated that they were "very comfortable" initiating conversation regarding these topics. Fifty-five percent said they were only likely to discuss sexuality and intimacy if the patient/partner initiated the discussion; however, 95% agreed that the patient should not have this responsibility. Although results represent findings from only 37 burn centers, the issues of sexuality and intimacy are not being effectively addressed in the participating centers. Designated staff to provide education is lacking, and there is limited comfort on the part of health care providers in initiating such conversations. These factors seem to often prevent burn care professionals from adequately addressing burn survivor's sexuality and intimacy needs and establish the need for further development of training and educational materials specific to sexuality, intimacy, and

Full Text Available Malva sylvestris, Punica granatum, Amygdalus communis, Arnebia euchroma and Scrophularia deserti are important medicinal plants in Iranian traditional medicine (Unani whose have been used as remedy against edema, burn, and wound and for their carminative, antimicrobial and anti-inflammatory activities. The ethanol extracts of M. sylvestris and P. granatum flowers, A. communis leaves, A. euchroma roots and S. deserti stems were used to evaluate the burn healing activity in alloxan-induced diabetic rats. Burns were induced in Wistar rats divided into nine groups as following; Group-I: normal rats were treated with simple ointment base (control, Group-II: diabetic rats were treated with simple ointment base (control, Groups-III and -VII: diabetic rats were treated with simple ointment base containing of extracts (diabetic animals, Groups VIII: diabetic rats were treated with simple ointment base containing of mixed extracts, Group-IX: diabetic rats received the standard drug (Silver Sulfadiazine. The efficacy of treatments was evaluated based on wound area, epithelialization time and histopathological characteristics. Wound contraction showed that there is high significant difference between the different groups (p<0.001. At the 18th day, A. euchroma, S. deserti, A. communis and mixed extract ointment treated groups healed 80-90%. At the 9th and 18th days the experiment, the best results were obtained with A. communis and standard drug, when compared to the other groups as well as to the controls. It may be concluded that almond leaves (sweet and bitter formulated in the simple ointment base is effective in the treatment of burns and thus supports its traditional use.

carried out in the dedicated burns theatre. The total expenditure for the study period was Indian Rupees (Rs) 46,488,067 or US$ 845,237. At 1 US$=Rs 55 it makes the cost per patient to be US$ 1060.5. Almost 70% of cost of burn management resulted from salaries, followed by investigations (11.56%) and dressings (8.24%). The mean cost of investigations per patient was Rs 6742.46 (US$ 122.59). Only 147/797 patients received 322 units of blood. Thus, the average cost of blood transfusion for all admissions was Rs 521.17 (US$ 9.47). Our study is evidence to direct costs of providing burn care in a tertiary centre of a low income country, and the large number of patients in our study while averaging the costs also validates the estimates. The 'reasonability' of care being delivered is defined by adequate resuscitation, daily topical dressings, appropriate surgery (escharotomy, debridement, and skin grafting), adequate nutrition and physical therapy. The 'reasonability' of outcomes can be measured by mortality figures. The bottom line of management is strict observation by burn staff. The low mean hospital stay also reflects our admission and discharge policy which is to benefit the maximum number of patients who require resuscitative/intensive care, and who have extensive and deep wounds, or injury of critical nature. We conclude that providing burn care based on our model can be emulated in other LICs as the costing is driven by 'necessity of expense' rather than 'ability to spend'.

Valid and reliable heuristic devices facilitating optimal wound care are lacking. The objectives of this study were to establish content validation data for a set of wound care algorithms, to identify their associated strengths and weaknesses, and to gain insight into the wound care decision-making process. Forty-four registered nurse wound care experts were surveyed and interviewed at national and regional educational meetings. Using a cross-sectional study design and an 83-item, 4-point Likert-type scale, this purposive sample was asked to quantify the degree of validity of the algorithms' decisions and components. Participants' comments were tape-recorded, transcribed, and themes were derived. On a scale of 1 to 4, the mean score of the entire instrument was 3.47 (SD +/- 0.87), the instrument's Content Validity Index was 0.86, and the individual Content Validity Index of 34 of 44 participants was > 0.8. Item scores were lower for those related to packing deep wounds (P valid and reliable definitions. The wound care algorithms studied proved valid. However, the lack of valid and reliable wound assessment and care definitions hinders optimal use of these instruments. Further research documenting their clinical use is warranted. Research-based practice recommendations should direct the development of future valid and reliable algorithms designed to help nurses provide optimal wound care.

Objective: To explore the methods and effects of wound repair and functional reconstruction of high-voltage electrical burns in wrists. Methods: From January 2009 to June 2016, 71 patients with high-voltage electrical burns in wrists were hospitalized, with 118 wrist wounds including 21 of type Ⅰ, 69 of type Ⅱ, 9 of type Ⅲ, and 19 of type Ⅳ. According to the wrist injuries, different surgical operations were performed. Forearm amputation was conducted in 20 wrists with necrosis in the distal end. On the basis of fasciotomy for decompression, early debridement was performed on the other 98 wrist wounds. After debridement, wounds with area ranging from 10 cm×7 cm to 30 cm×18 cm were repaired with tissue flaps with abundant blood supply. Thirty-two wounds were repaired with pedicled groin flaps, 11 wounds with pedicled paraumbilical flaps, 3 wounds with pedicled anterolateral thigh island flaps, 9 wounds with combined abdominal axial pattern flaps, 37 wounds with free skin flaps or myocutaneous flaps, and 6 wounds with flow-through descending branch of lateral femoral circumflex artery flaps, with tissue flap area ranging from 12 cm×8 cm to 34 cm×20 cm. Ulnar artery or radial artery vascular reconstruction was performed in 20 wrist wounds. Forty-one donor sites were sutured directly, while 14 were closed by thin split-thickness skin grafts from same-side thighs, and 43 were closed by thin split-thickness skin grafts from opposite-side thighs. Fifty-three wrist wounds were performed with tendon and nerve repair surgery, of which 20 were performed with simple tendon and nerve release surgery. Flexor digitorum profundus tendons and (or) flexor pollicis longus tendons were reconstructed with autologous or allogeneic tendon transplantation in 33 wrist wounds, and the median nerve was repaired with sural nerve graft in 21 wrist wounds. In 6 to 24 months after the last operation, tendon function of 53 wrist wounds which had tendon repair was evaluated with finger

To observe the clinical efficacy of negative pressure wound therapy (NPWT) in combination with porcine acellular dermal matrix (ADM) dressing for repairing deep burn wounds in limbs of patients with non-surgical treatment. Thirty-two patients with deep partial-thickness burn to full-thickness burn on the limbs admitted to our ward from June 2012 to December 2015, conforming to the inclusion criteria, were divided into group NPWT (n=10, treated with interval negative pressure drainage at -16.6 kPa), group ADM (n=7, treated with porcine ADM dressing), and group NPWT+ ADM (n=15, treated with interval negative pressure drainage and porcine ADM dressing as above) according to the random number table and patient's consent. After being treated for 21 d, residual wounds were cured by routine dressing change using sulfadiazine silver. On post treatment day (PTD) 7, 14, and 21, wound gross observation was conducted, wound drainage fluid volume was recorded, and wound healing rate was calculated. Wound secretion was collected for bacterial culture before treatment and on PTD 21, and bacterial clearance effect was recorded. The wound healing time was also recorded. Measurement data were processed with analysis of variance for repeated measurement, one-way analysis of variance, and LSD test. Eenumeration data were processed with chi-square test or Fisher's exact test. (1) On PTD 7, the wounds of patients in group NPWT and group NPWT+ ADM were significantly shrinked as compared with those before treatment. Skin paddle scattered on the wounds of patients in group NPWT+ ADM on PTD 7. The wounds of patients in group ADM were slightly shrinked on PTD 7 as compared with those before treatment. On PTD 14, the wounds of patients in group NPWT were slightly shrinked as compared with those on PTD 7, while those in group NPWT+ ADM were significantly shrinked as compared with those on PTD 7. Skin paddle on the wounds of patients in group NPWT+ ADM on PTD 14 were increased and fused. The

The focus of the current study was to interrogate the predictive potential of laser-induced autofluorescence (LIAF) by objectively assessing collagen synthesis in burn wound granulation tissues ex vivo. Prior grafting, granulation tissues (20 samples) following burn injury were collected from 17 subjects of age range 18- 60 years with patient/donor consent and the corresponding autofluorescence spectra were recorded at 325 nm He-Cd laser (≈ 2 mW) excitations. The resulting endogenous collagen intensity from the above tissue samples was computed by normalizing the NADH levels. In addition, the hydroxyproline content was also estimated biochemically from the same granulation tissues. A comparative assessment of both LIAF and biochemical estimations for endogenous collagen by hydroxyproline resulted in strong positive correlation among them. The above relevant observations suggest that LIAF is equally informative as that of biochemical estimations, in evaluating endogenous collagen content in wound granulation tissues. Thus, it can be concluded that LIAF has the predictive potential, as a non-invasive objective tool to measure the endogenous collagen levels in wound biopsy tissues and provide complementary data conducive for making clinical decisions.

This experiment was performed to compare the effects of Phenytoin (PHT) and Hypericin (HP) cream on healing of burn wounds in rats. Twenty rats were divided into 3 groups and second-degree burn wounds were created. The burn wounds in the first, second, and third groups were covered twice daily with PHT cream, HP cream, and saline (control), respectively. At the end of days 3, 7, 14, and 21, full-thickness skin biopsies were done for histopathologic and immunohistochemical analyses. Histopathologic evaluations at the 14th day showed that re-epithelialization scores were greater in the HP group than the PHT group, but on day 21, re-epithelialization scores were higher in the PHT group than the HP group. Collagen content on days 3 and 14 in the PHT group was found to be higher than in the HP group. Well-vascularized granulation tissue on day 7 in the PHT group was higher than in other groups. HP and PHT groups had a significant increase in VEGF and TGF-b expression in burn wound healing area compared to the control group on all days. Topical application of HP can promote re-epithelialization in burn wounds to shorten the wound healing time for superficial burns. Phenytoin, on the other hand, contributes to healing by increasing vascularized granulation tissue and collagen synthesis through re-epithelialization. The increased VEGF and TGF-b expression following PHT and HP treatment strongly indicate that PHT and HP treatment promotes VEGF and TGF-b production and action in the burn wound area.

Background: The seed oil of Zanthoxylum bungeanum Maxim (ZBSO) is considered to be rich source of fatty acids, mainly oleic and linoleic acids, and has been used for the treatment of burns in Chinese medicine. Objective: We evaluated the healing efficacy of ZBSO and explored its possible mechanism on scalded rats. Materials and Methods: Sprague-Dawley rat models with deep second-degree burns were set up, and ZBSO (500 and 1000 μl/wound) was topically applied twice daily for 7 days and then once daily until wound healing. The therapeutic effects of ZBSO were evaluated by observing wound closure time, decrustation time, wound-healing ratio, and pathological changes. Collagen type-III, matrix metalloproteinase-2 (MMP-2), MMP-9, phospho-nuclear factor-κB (p-NF-κB) p65, inhibitor of NF-κB subunit α p-IκBα, and inhibitor of NF-κB subunit α (IκBα) expression were determined using Western blotting. Results: The ZBSO-treated group showed a higher wound-healing ratio and shorter decrustation and wound closure times than the untreated group. The topical application of ZBSO increased collagen synthesis as evidenced by an increase in hydroxyproline level and upregulated expression of collagen type-III on days 7, 14, and 21 posttreatment. A reduction in MMP-2 and MMP-9 expressions also confirmed the collagen formation efficacy of ZBSO. Furthermore, there was a significant increase in superoxide dismutase levels and a decrease in malondialdehyde levels in ZBSO-treated wounds. ZBSO also decreased tumor necrosis factor alpha, interleukin-1 (IL-1) β, and IL-6 levels in serum, upregulated IκBα, and downregulated p-NF-κB p65 and p-IκBα expression in vivo, indicating the anti-inflammatory action of ZBSO. Conclusion: ZBSO has significant potential to treat burn wounds by accelerating collagen synthesis and the anti-inflammatory cascade of the healing process. SUMMARY The seed oil of Zanthoxylum bungeanum Maxim (ZBSO) is rich of fatty acidsThe healing efficacy of ZBSO on

In this review, we describe current and future potential wound healing treatments for acute and chronic wounds. The current wound healing approaches are based on autografts, allografts, and cultured epithelial autografts, and wound dressings based on biocompatible and biodegradable polymers. The Food and Drug Administration approved wound healing dressings based on several polymers including collagen, silicon, chitosan, and hyaluronic acid. The new potential therapeutic intervention for wound healing includes sustained delivery of growth factors, and siRNA delivery, targeting micro RNA, and stem cell therapy. In addition, environment sensors can also potentially utilize to monitor and manage micro environment at wound site. Sensors use optical, odor, pH, and hydration sensors to detect such characteristics as uric acid level, pH, protease level, and infection – all in the hopes of early detection of complications.

Considering the infection and second trauma caused by dressing changes, development of antibacterial and low-adherent wound dressings is urgently needed. Silver ion is a widely used antimicrobial agent, but its cytotoxicity remains a problem. In this study, low-adherent PAM (polyacrylamide) hydrogel incorporated with less toxic AgNP (silver nanoparticle), was immobilized onto PET (poly(ethylene terephthalate)) substrates by an IPN (interpenetrating polymer network) method. The modified PET is effectively antibacterial and the surface is significantly less adherent than untreated PET. However, silver-resistant bacteria become a potential problem. Thus, ionic 5,5-dimethylhydantoin (DMH) analogues containing either a quaternary ammonium moiety or a phosphonate functional group were designed and synthesized. The DMH analogues were converted to antibacterial N-chloramine counterparts through chlorination to serve as potential alternatives to AgNP. The N-chloramine with a structural cation exhibited distinctly enhanced antibacterial functions both in solution and after immobilization on fabrics.

At present there is no established national minimum data set (MDS) for generic wound assessment in England, which has led to a lack of standardisation and variable assessment criteria being used across the country. This hampers the quality and monitoring of wound healing progress and treatment. To establish a generic wound assessment MDS to underpin clinical practice. The project comprised 1) a literature review to provide an overview of wound assessment best practice and identify potential assessment criteria for inclusion in the MDS and 2) a structured consensus study using an adapted Research and Development/University of California at Los Angeles Appropriateness method. This incorporated experts in the wound care field considering the evidence of a literature review and their experience to agree the assessment criteria to be included in the MDS. The literature review identified 24 papers that contained criteria which might be considered as part of generic wound assessment. From these papers 68 potential assessment items were identified and the expert group agreed that 37 (relating to general health information, baseline wound information, wound assessment parameters, wound symptoms and specialists) should be included in the MDS. Using a structured approach we have developed a generic wound assessment MDS to underpin wound assessment documentation and practice. It is anticipated that the MDS will facilitate a more consistent approach to generic wound assessment practice and support providers and commissioners of care to develop and re-focus services that promote improvements in wound care.

Polyneuropathy is a debilitating condition which may be associated with large burns. The aim of this integrative review is to identify factors that contribute to the development of critical care polyneuropathy in patients admitted to an intensive care unit with a severe burn injury. PubMed, Scopus, CINHAL and EMBASE were searched up until July 2016. Studies/case reports focusing on critical care polyneuropathy for burn injured patients were included. The ten studies, included a total of 2755 burns subjects and identified 128 critical care polyneuropathy patients with an incidence of 4.4%. Three case reports identified prolonged ventilation and development of critical care neuropathy. Overall, factors identified as contributing to the development of critical care polyneuropathy in burn injured patients included prolonged ventilation (>7 days), large and deep total body surface area burns (mean TBSA 40%), and sepsis. Critical care polyneuropathy in burn patients remains challenging to diagnose and treat. To date, there is a lack of long term studies describing the impact of critical care polyneuropathy on functional performance or participation in activities of daily living in the burns population and this is consistent with the general literature addressing the lack of follow up assessments and long term consequences of persistent muscle weakness.

Burn injury is one of the most common reasons for admission in paediatric population. There is currently no international consensus on the best wound dressing material. Aquacel Ag, a new silver containing hydrofiber dressing material has been reported to produce good clinical results. Yet, only a limited number of studies exist in the paediatric population. This study aims to review our experience of burn management over the past 5 years and to evaluate the effectiveness of Aquacel Ag in the management of partial thickness burns. A retrospective review of all patients admitted for burn injury between January 2010 and December 2014 was conducted. Patients' demographics, mechanism of injury, body surface areas involved, treatment applied, and clinical outcomes were analyzed. Patients with superficial injury, full thickness burns that required surgical debridement, burn area less than 2 % or more than 25 % of total body surface area, or incomplete clinical data were excluded from the comparative study. A total of 119 patients were identified. 114 (96 %) was due to domestic injury, of which 108 (91 %) was food-related. The most commonly affected areas were limbs (n = 89, 74.8 %), followed by trunk (n = 62, 74.8). 84 patients fulfilled the inclusion criteria and were recruited into the study. 31 patients received Aquacel Ag dressing and 53 patients received standard paraffin gauze dressing. The two groups showed no statistical difference in age, sex, percentage of total body surface area involved, and infection rate. Outcomes of patients treated with Aquacel Ag were compared with patients treated with standard dressing. The mean hospital stay was significantly shorter for the Aquacel Ag group (14.26 vs 23.45, p = 0.045). Aquacel Ag group required much less frequent dressing change (5.67 vs 20.59, p = 0.002). 5 patients in standard dressing group developed hypertrophic scar and required prolonged pressure garment, whereas only one hypertrophic scar was

Although the benefits of wound care services and multidisciplinary team care have been well elaborated on in the literature, there is a gap in the actual practice of wound care and the establishment of an efficient referral system. The conceptual framework for establishing efficient wound management services requires elucidation.A wound care center was established in a tertiary hospital in 2010, staffed by an integrated multidisciplinary team including plastic surgeons, a full-time coordinator, a physical therapist, occupational therapists, and other physician specialists. Referral patients were efficiently managed following a conceptual framework for wound care. This efficient wound management service consists of 3 steps: patient entry and onsite immediate wound debridement, wound re-evaluation, and individual wound bed preparation plan. Wound conditions were documented annually over 4 consecutive years.From January 2011 to December 2014, 1103 patients were recruited from outpatient clinics or inpatient consultations for the 3-step wound management service. Of these, 62% of patients achieved healing or improvement in wounds, 13% of patients experienced no change, and 25% of patients failed to follow-up. The outcome of wound treatment varied by wound type. Sixty-nine percent of diabetic foot ulcer patients were significantly healed or improved. In contrast, pressure ulcers were the most poorly healed wound type, with only 55% of patients achieving significantly healed or improved wounds.The 3-step wound management service in the wound care center efficiently provided onsite screening, timely debridement, and multidisciplinary team care. Patients could schedule appointments instead of waiting indefinitely for care. Further wound condition follow-up, education, and prevention were also continually provided.

Burns to the perineum are frequently exposed to faeces. Diverting colostomy is often described to prevent faecal soiling. Because this technique is invasive with frequent complications, use of non-surgical devices including specifically designed faecal management systems has been reported in perineal burns. In order to standardise the faecal management strategy in patients with perineal burns, a group of French experts was assembled. This group first evaluated the ongoing practice in France by analysing a questionnaire sent to every French burn centre. Based on the results of this study and on literature data, the experts proposed recommendations on the management of perineal burns in adults. Specifically designed faecal management systems are the first-line method to divert faeces in perineal burns. The working group proposed recommendations and an algorithm to assist in decisions in the management of perineal burns in four categories of patients, depending on total burn skin area, depth and extent of the perineal burn. In France, non-surgical devices are the leading means of faecal diversion in perineal burns. The proposed algorithm may assist in decisions in the management of perineal burns. The expert group emphasises that large clinical studies are needed to better evaluate these devices. Copyright © 2013 Elsevier Ltd and ISBI. All rights reserved.
Full Text Available AIM: To study the effect of vasoactive intestinal peptide (VIP on wound healing in experimental alkali burns of the cornea. METHODS: Twenty-seven albino rabbits, weighing 3.2±0.75 kg were used. Alkali burns were induced on corneas by applying 10 mm Whatman paper No:50 soaked in 1 mol/L NaOH. They have further classified into 5 groups as follows: 1 control group given no treatment (n=5; 2 VIP given subconjunctivally (n=6; 3 VIP injected into anterior chamber (n=6; 4 NaCl 0.9% given subconjunctivally (n=5; 5 NaCl 0.9% given into the anterior chamber (n=5. All treatment protocols except control group were followed by topical eye drops composed of VIP at two hourly intervals for one week from 8 a.m. to 6 p.m. RESULTS: VIP treated groups of rabbits with alkali burns were found to have better wound healing findings histo-pathologically when compared to those of control group who have received no treatment on day 30. No differences were observed between groups in respect to degree of polymorphonuclear leukocytes (PMNL infiltration and degree of loss of amorphous substrate on day 15. However, PMNL infiltration and degree of loss of amorphous substrate were lower in Groups 2 and 3 when compared to that of control group on day 30 (P(0.05. CONCLUSION: We have shown that VIP has positive effects on alkali induced corneal burns. VIP may inhibit PMNL migration to cornea through an immunomodulatory effect. Inhibition of PMNL migration might reduce the release of collagenases and this might prevent the extracellular amorphous substance loss.

Most of the literature focuses on the resources required to manage particular wound types, rather than the cost of wounds to health-care organisations. Until this information is available, wound care is unlikely to be a management priority.

As the prevalence of chronic wounds continues to rise, the need for point of care wound assessment has also increased. While a variety of technologies have been developed to improve diagnostic abilities and monitoring of wounds, none have proven completely effective in all settings. Further, many of the stalwart wound management techniques remain costly, time consuming, and technically challenging. The two key pivotal events of ischemia and infection can lead to limb loss. A relatively new crop of fluorescence-based technologies, including devices that measure pathogenic auto-fluorescence, fluorescence angiography, or map cutaneous oxygenation, are increasingly being utilized for adjunct wound assessment-both clinical and operative settings can address these events. These technologies offer rapid, efficient, visual, and quantitative data that can aid the wound provider in evaluating the viability of tissues, ensuring adequate perfusion, and optimizing wound bed preparation. In the following review, pathogenic auto-fluorescence is compared to gross evaluation of wound infection and culture based diagnostics, indocyanine green fluorescence angiography is compared to various methods of visual and physical assessments of tissue perfusion by the practitioner, and cutaneous oxygenation is compared to clinical signs of ischemia. We focus on the current applications of fluorescence technologies in wound management, with emphasis placed on the evidence for clinical and operative implementation, a safety analyses, procedural limitations, and the future direction of this growing field of wound assessment.

The body´s way of debridement is an autolytic one, but especially in stagnating chronic wounds it may be slowed down due to the pathological chronification process. So a dressing for chronic wounds, they added, should ideally support autolytic debridement. This prompted them to perform a 10-patient evaluation to find.

Chronic wounds are a substantial clinical problem affecting millions of people worldwide. Pathophysiologically, chronic wounds are stuck in the inflammatory state of healing. The role of bacterial biofilms in suppression and perturbation of host response could be an explanation for this observation....... An inhibiting effect of bacterial biofilms on wound healing is gaining significant clinical attention over the last few years. There is still a paucity of suitable animal models to recapitulate human chronic wounds. The etiology of the wound (venous insufficiency, ischemia, diabetes, pressure) has to be taken...... into consideration as underlying pathophysiological mechanisms and comorbidities display tremendous variation in humans. Confounders such as infection, smoking, chronological age, sex, medication, metabolic disturbances, and renal impairment add to the difficulty in gaining systematic and comparable studies...

Infections in burn patients are still the principal cause of complications in burn injuries. The aim of this study is to assess a new strategy for burn wound management in view of infection prevention and treatment in the experience of the Burn Treatment Center in Siemianowice Śląskie. The applied methodology involved the analysis of patient records describing the hospital's epidemiological situation between 2014 and 2016. The analysis also included the use and cost of antibiotics, silver-containing dressings, and other antiseptics relative to the number of sepsis cases, including those caused by Pseudomonas aeruginosa, as well as the mortality ratio. The total costs of prevention and treatment of infections were reduced, while the use of silver-containing dressings and antiseptics increased. The number of patients with sepsis decreased, including cases caused by P. aeruginosa, and the mortality ratio was reduced. Introducing a strategy for burn wound-oriented infection prevention and treatment in burn patients provides a number of benefits. It is also cost-effective. Using locally applied active dressings and antiseptics can be a welcome choice for often-unnecessary antibiotic therapy of a suspected or existing burn wound infection. © 2017 Medicalhelplines.com Inc and John Wiley & Sons Ltd.

There has been an explosion of basic science results in the field of wound care over the past 20 years. Initially, wound dressings were the only therapeutic option available to the wound practitioner. With advanced basic science knowledge, technical innovation, and the recent participation of pharmaceutical companies, the wound clinician now has an arsenal of dressings, biological tissue replacements, gene therapy, and cell-based treatment options. What has not, however, kept pace with these changes is the education and practical training for those treating nonhealing wounds. The pace of innovation in wound diagnostic tools has also lagged, creating even more pressure on the clinician to use experience, skill, and training to properly diagnose the root cause for the nonhealing wound. As wound healing is not considered a medical specialty, there is no formal training process for physicians, and subsequently, allied health practitioners are often the only ones available to provide care for these complex patients. Wound care training, however, is also not part of any formal curriculum for these healthcare providers as well, creating confusion for patients, payors, regulators, researchers, and product manufacturers. In all other fields of medicine there is a formal process in place for physicians to train, certify, and credential. Medicine is constantly evolving and there have been several new fields of specialty care created over the past two decades that can serve as examples for the wound care field to follow. Without academic-based, clinical residency/fellowship training in wound healing ultimately leading to formal certification, the field will be unable to achieve an appropriate status in the medical establishment. Achieving this goal will impact product innovation, payment, and the sustainability of the field. The enhanced understanding of normal and dysregulated wound healing processes, which have been uncovered by basic scientists, has translated to the

Major complications of diabetes mellitus include lower leg and foot ulcers, which can result in amputation. Further study is needed to determine optimal treatments for these challenging wounds. Growth factor therapy and hyperbaric oxygen (HBO) treatments are 2 advanced therapeutic modalities that hold promise. This descriptive, retrospective review investigated healing rates of patients with diabetes mellitus and lower- extremity ulcers managed by growth factor therapy and HBO as compared to standard wound care. Retrospective review of medical records. We reviewed medical records of 89 patients with diabetes and lower-extremity wounds treated at a major outpatient wound care program in the southwestern United States. Patients were categorized according to 4 treatment modalities: (1) standard wound care, (2) growth factor therapy, (3) standard wound care plus HBO, and (4) growth factor therapy plus HBO. Wounds were measured at the start of the analysis and then weekly for a total of 8 weeks. The change in wound volume from the first to the eighth week was recorded. All patient groups demonstrated healing with the patients who received growth factor therapy alone and those who received growth factor therapy and the HBO treatments demonstrating the greatest decrease in wound volume over the 8 weeks. A 2-by-2 factorial analysis of covariance demonstrated that patients who received HBO as part of their wound care regimen demonstrated significantly greater healing than patients who received only standard wound care or growth factor therapy (P wound healing in this study, it should be noted that the mean size of the wounds in this group was 2.8 times larger than the mean size of the wounds in the other groups. Patients managed in a state-of-the-art wound care center experienced progress toward wound healing, regardless of the treatment modality selected. Those who received HBO as part of their wound care regimen healed faster than those who received standard treatment or

Chemical burns take up a high proportion of burns admissions and can penetrate deep into tissues. Various reagents have been applied in the treatment of skin chemical burns; however, no optimal reagent for skin chemical burns currently exists. The present study investigated the effect of topical body protective compound (BPC)-157 treatment on skin wound healing, using an alkali burn rat model. Topical treatment with BPC-157 was shown to accelerate wound closure following an alkali burn. Histological examination of skin sections with hematoxylin–eosin and Masson staining showed better granulation tissue formation, reepithelialization, dermal remodeling, and a higher extent of collagen deposition when compared to the model control group on the 18th day postwounding. BPC-157 could promote vascular endothelial growth factor expression in wounded skin tissues. Furthermore, 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide and cell cycle analysis demonstrated that BPC-157 enhanced the proliferation of human umbilical vein endothelial cells (HUVECs). Transwell assay and wound healing assay showed that BPC-157 significantly promoted migration of HUVECs. We also observed that BPC-157 upregulated the expression of VEGF-a and accelerated vascular tube formation in vitro. Moreover, further studies suggested that BPC-157 regulated the phosphorylation level of extracellular signal-regulated kinases 1 and 2 (ERK1/2) as well as its downstream targets, including c-Fos, c-Jun, and Egr-1, which are key molecules involved in cell growth, migration, and angiogenesis. Altogether, our results indicated that BPC-157 treatment may accelerate wound healing in a model of alkali burn-induced skin injury. The therapeutic mechanism may be associated with accelerated granulation tissue formation, reepithelialization, dermal remodeling, and collagen deposition through ERK1/2 signaling pathway.

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

Wound care is a classic example of a surgical realm with a great variation in care. The diversity in wounds and wound treatments, the limited amount of convincing evidence, and the diverging opinions among doctors and nurses involved in wound care contribute to this undesirable variation in care.

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 μm 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, γ-ray irradiation, UV light exposure, and lyophilized process. From the results of MTT, IL-8, IL-1α, IL-6, and TNF-α 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

To study migration of syngeneic bone marrow MSCs and skin fibroblasts (FB, labeled by fluorochromes, after intravenous (IV and local transplantation in a rat burn wound model (BWM. Methods. Rats were divided into 3 groups: C – without burn + IV injection of labeled MSCs and FBs mixture; O1 – BWM + IV injection of labeled MSCs and FBs mixture; O2 – BWM + fibrin matrix filled with labeled cell mixture. MSCs were labeled by green fluorochrome, and fibroblasts – by red one. The presence of labeled cells in cryocuts of the skin, liver, kidney and bone marrow was assessed on the 3 and 7 days after transplantation. Results. Skin FBs selective migration to the regenerating burn wound and MSCs accumulation in the kidneys were found in rats of group O1 on day 7 after the IV injection. The labeled cells proliferated in the transplanted fibrin matrix and participated in the wound regeneration. MSCs partly migrated to the bone marrow after the IV injections. Conclusions. IV transplanted syngeneic bone marrow MSCs and skin FBs (passage 0 migrate to the burn wound and participate in the healing. Migration of bone marrow MSCs in the kidneys can prevent kidney failure after burn.

To provide information about palliative wound care management strategies for palliative patients and their circles of care. This continuing education activity is intended for physicians and nurses with an interest in skin and wound care. After participating in this educational activity, the participant should be better able to: 1. Recognize study findings, assessment tools, and non-pharmacologic strategies used for patients with palliative wounds. 2. Summarize pharmacologic and dressing treatment strategies used for wound care management of palliative patients. The principles of palliative wound care should be integrated along the continuum of wound care to address the whole person care needs of palliative patients and their circles of care, which includes members of the patient unit including family, significant others, caregivers, and other healthcare professionals that may be external to the current interprofessional team. Palliative patients often present with chronic debilitating diseases, advanced diseases associated with major organ failure (renal, hepatic, pulmonary, or cardiac), profound dementia, complex psychosocial issues, diminished self-care abilities, and challenging wound-related symptoms. This article introduces key concepts and strategies for palliative wound care that are essential for interprofessional team members to incorporate in clinical practice when caring for palliative patients with wounds and their circles of care.

Burn wounds are often characterized by injury depth, which then dictates wound management strategy. While most superficial burns and full thickness burns can be diagnosed through visual inspection, clinicians experience difficulty with accurate diagnosis of burns that fall between these extremes. Accurately diagnosing burn severity in a timely manner is critical for starting the appropriate treatment plan at the earliest time points to improve patient outcomes. To address this challenge, research groups have studied the use of commercial laser Doppler imaging (LDI) systems to provide objective characterization of burn-wound severity. Despite initial promising findings, LDI systems are not commonplace in part due to long acquisition times that can suffer from artifacts in moving patients. Commercial LDI systems are being phased out in favor of laser speckle imaging (LSI) systems that can provide similar information with faster acquisition speeds. To better understand the accuracy and usefulness of commercial LSI systems in burn-oriented research, we studied the performance of a commercial LSI system in three different sample systems and compared its results to a research-grade LSI system in the same environments. The first sample system involved laboratory measurements of intralipid (1%) flowing through a tissue simulating phantom, the second preclinical measurements in a controlled burn study in which wounds of graded severity were created on a Yorkshire pig, and the third clinical measurements involving a small sample of clinical patients. In addition to the commercial LSI system, a research grade LSI system that was designed and fabricated in our labs was used to quantitatively compare the performance of both systems and also to better understand the "Perfusion Unit" output of commercial systems.

The aim of this study was to investigate the effects of subconjunctivally administered mesenchymal stem cells (MSCs) on corneal wound healing in the acute stage of an alkali burn. A corneal alkali burn model was generated by placing a piece of 3-mm diameter filter paper soaked in NaOH on the right eye of 48 Sprague-Dawley female rats. 24 rats were administered a subconjunctival injection of a suspension of 2×106 MSCs in 0.1 ml phosphate-buffered saline (PBS) on day 0 and day 3 after the corneal alkali burn. The other 24 rats were administered a subconjunctival injection of an equal amount of PBS as a control. Deficiencies of the corneal epithelium and the area of corneal neovascularization (CNV) were evaluated on days 3 and 7 after the corneal alkali burn. Infiltrated CD68+ cells were detected by immunofluorescence staining. The mRNA expression levels of macrophage inflammatory protein-1 alpha (MIP-1α), tumor necrosis factor-alpha (TNF-α), monocyte chemotactic protein-1 (MCP-1) and vascular endothelial growth factor (VEGF) were analyzed using real-time polymerase chain reaction (real-time PCR). In addition, VEGF protein levels were analyzed using an enzyme-linked immunosorbent assay (ELISA). MSCs significantly enhanced the recovery of the corneal epithelium and decreased the CNV area compared with the control group. On day 7, the quantity of infiltrated CD68+ cells was significantly lower in the MSC group and the mRNA levels of MIP-1α, TNF-α, and VEGF and the protein levels of VEGF were also down-regulated. However, the expression of MCP-1 was not different between the two groups. Our results suggest that subconjunctival injection of MSCs significantly accelerates corneal wound healing, attenuates inflammation and reduces CNV in alkaline-burned corneas; these effects were found to be related to a reduction of infiltrated CD68+ cells and the down-regulation of MIP-1α, TNF-α and VEGF.

To report the cost-effectiveness of a tailored handheld computerized procedural preparation and distraction intervention (Ditto) used during pediatric burn wound care in comparison to standard practice. An economic evaluation was performed alongside a randomized controlled trial of 75 children aged 4 to 13 years who presented with a burn to the Royal Children's Hospital, Brisbane, Australia. Participants were randomized to either the Ditto intervention (n = 35) or standard practice (n = 40) to measure the effect of the intervention on days taken for burns to re-epithelialize. Direct medical, direct nonmedical, and indirect cost data during burn re-epithelialization were extracted from the randomized controlled trial data and combined with scar management cost data obtained retrospectively from medical charts. Nonparametric bootstrapping was used to estimate statistical uncertainty in cost and effect differences and cost-effectiveness ratios. On average, the Ditto intervention reduced the time to re-epithelialize by 3 days at AU$194 less cost for each patient compared with standard practice. The incremental cost-effectiveness plane showed that 78% of the simulated results were within the more effective and less costly quadrant and 22% were in the more effective and more costly quadrant, suggesting a 78% probability that the Ditto intervention dominates standard practice (i.e., cost-saving). At a willingness-to-pay threshold of AU$120, there is a 95% probability that the Ditto intervention is cost-effective (or cost-saving) against standard care. This economic evaluation showed the Ditto intervention to be highly cost-effective against standard practice at a minimal cost for the significant benefits gained, supporting the implementation of the Ditto intervention during burn wound care.

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

Reliability and validity of 3D photography (3D LifeViz™ System) compared to digital planimetry (Visitrak™) has been established in a compliant cohort of children with acute burns. Further research is required to investigate these assessment tools in children representative of the general pediatric burns population, specifically children under the age of three years. To determine if 3D photography is a reliable wound assessment tool compared to Visitrak™ in children of all ages with acute burns ≤10% TBSA. Ninety-six children (median age 1 year 9 months) who presented to the Royal Children's Hospital Brisbane with an acute burn ≤10% TBSA were recruited into the study. Wounds were measured at the first dressing change using the Visitrak™ system and 3D photography. All measurements were completed by one investigator and level of agreement between wound surface area measurements was calculated. Wound surface area measurements were complete (i.e. participants had measurements from both techniques) for 75 participants. Level of agreement between wound surface area measurements calculated using an intra-class correlation coefficient (ICC) was excellent (ICC 0.96, 95% CI 0.93, 0.97). Visitrak™ tracings could not be completed in 19 participants with 16 aged less than two years. 3D photography could not be completed for one participant. Barriers to completing tracings were: excessive movement, pain, young age or wound location (e.g. face or perineum). This study has confirmed 3D photography as a reliable alternative to digital planimetry in children of all ages with acute burns ≤10% TBSA. In addition, 3D photography is more suitable for very young children given its non-invasive nature. Copyright © 2015 Elsevier Ltd and ISBI. All rights reserved.

The application of sterile and clean procedure to the practice of wound care nursing was examined. This prospective, descriptive study surveyed staff nurses regarding glove use. Seven hundred forty-three staff nurses from five health care agencies in the San Francisco Bay Area responded to the survey. A self-report wound care survey instrument was developed by Nursing Consortium for Research and Practice members from information adapted from the wound care literature. The questionnaire comprised 31 questions and required approximately 10 minutes to complete. Nursing Consortium for Research and Practice members obtained approval from their respective institutional human subjects committees and distributed questionnaires among all nurses engaged in direct care. Some agency representatives personally handed the survey instruments to subjects, but most distributed them through their agencies personnel mailing systems. Seven hundred twenty-three (38%) of 1900 questionnaires were completed and returned to the five site coordinators. Differences were found between acute care and home health nurses. Acute care nurses were more likely than home care nurses to use sterile gloves in all wound care situations. Greater variation was found with regard to sterile technique in wound care practice than in previously reported studies. Although patient risk factors and wound type significantly influenced the choice of sterile or clean gloves, additional environmental and personal factors exerted considerable influence. These included health care setting, degree of professional education, and nurses' experiential background. Attempts to modify practice through policy change alone may not be sufficient to overcome resistance to change. Instead, it may be necessary for nurses to "unlearn" lessons from basic nursing education before they can adopt to new practices and clinical policies.
Full Text Available Objective: To determine the trends in burn admissions, and aetiology, severity and mortality of patients admitted to the Burns Intensive Care Unit of the Komfo Anokye Teaching Hospital from May 2009 to April 2016 (7 years. Methods: Patients’ data used in this longitudinal and retrospective study were accessed from the records of the Reconstructive Plastic Surgery and Burns Unit. Processed data were depicted in tables and figures as appropriate. Univariate and multivariate analysis and Pearson’s rank correlation were used in comparing relevant groups. Data analysis was conducted using Excel version 2013 and SPSS version 17.0. Results: A total of 681 patients, with a male to female ratio of 1.1:1.0, were analysed. The average annual incidence was 97.28 with a progressive decline in incidence. Mortality rate was 24.2%. Majority of the patients were children less than 10 years (43.5% with scalds as the main aetiology in this group. Open flame was the major aetiology of burns (49.9%. Majority of the patients spent less than 10 days on admission (67.1%. Mean total body surface area was 30.54%. There was correlation between TBSA and disposition, total body surface area and aetiology and number of days in the Burns Intensive Care Unit, total body surface area and aetiology, and aetiology and number of days in the Burns Intensive Care Unit. Conclusions: Children below 10 years were the main victims. There was a shift from scald to open flame burns in this current study. Mean total body surface area and mortality rate have increased. There is urgent need for prevention campaign of flame burn and first aid education on intensive burns.

The aim of this study was to review clinical data and outcomes of patients with burns in a Mexican non-burn intensive care unit (ICU). We did a retrospective analysis of our single-centre database of burn patients admitted to the ICU in the Hospital Civil Fray Antonio Alcalde (University Hospital). The sample was divided for analysis into two groups according to the outcome 'death' or 'discharge' from ICU. Overall mortality was 58.2%, without a decreasing trend in mortality rates through the years. We identified the presence of third-degree burns (odds ratio (OR) 1.5, p=0.003), and >49% total burned surface area (TBSA; OR 3.3, p≤0.001) was associated with mortality. Mean age was higher in deceased patients (38.2 years vs. 31.3 years, p=0.003) as was the TBSA (62.8% vs. 36.4%, p≤0.001). At multivariate analysis, inhalation injury was not associated with increased mortality, but it was with more mechanical ventilation days. Early surgical debridement/cleansing was performed in most patients; however, the mean of the procedures was 1.7 per patient in both groups. We identified significant factors associated with mortality. These variables and prognosis from non-burn ICUs differ broadly compared with burn intensive care units (BICUs); thus, more structured, multidisciplinary and specialised treatment strategies are still needed.

Global burn injuries have been described as the "forgotten public health crises" by the World Health Organization. Nearly 11 million people a year suffer burns severe enough to require medical attention; more people are burned each year than are infected with human immunodeficiency virus/acquired immunodeficiency syndrome and tuberculosis combined. Telemedicine has the potential to link experts in specialized fields, such as burn care, to regions of the world that have limited or no access to such specialized care. A multilevel telemedicine program was developed between Massachusetts General Hospital/Shriners Hospital in Boston, Massachusetts, and City Hospital #8 in Lviv, Ukraine. The program should lead to a sustainable improvement in the care of burn victims in Ukraine. The authors helped establish a Learning Center at City Hospital #8 in Lviv, Ukraine, through which they were able to consult from Shriners Hospital in Boston, on a total of 14 acute burn patients in Ukraine. This article discusses two case reports with the use of telemedicine and how it has allowed the authors to provide not only acute care consultation on an international scale, but also to arrange for direct expert examination and international transport to their specialized burn center in the United States. The authors have established a program through doctors from Massachusetts General Hospital/Shriner's Hospital in Boston, which works with a hospital in Ukraine and has provided acute consultation, as well as patient transportation to the United States for treatment and direct assessment.

Intensive care unit-acquired weakness is an evolving problem in the burn population. As patients are surviving injuries that previously would have been fatal, the focus of treatment is shifting from survival to long-term outcome. The rehabilitation of burn patients can be challenging; however, a certain subgroup of patients have worse outcomes than others. These patients may suffer from intensive care unit-acquired weakness, and their treatment, physiotherapy and expectations need to be adjusted accordingly. This study investigates the condition of intensive care unit-acquired weakness in our burn centre. We conducted a retrospective analysis of all the admissions to our burn centre between 2008 and 2012 and identified 22 patients who suffered from intensive care unit-acquired weakness. These patients were significantly younger with significantly larger burns than those without intensive care unit-acquired weakness. The known risk factors for intensive care unit-acquired weakness are commonplace in the burn population. The recovery of these patients is significantly affected by their weakness.

Wound healing is a process to repair the damaged tissue caused by thermal burn, incised wound, or stab wound. Although the wound healing has many aspects, it is common for dynamics of collagen fiber, such as decomposition, production, or growth, to be closely related with wound healing. If such the healing process can be visualized as a timelapse image of the collagen fiber in the same subject, one may obtain new findings regarding biological repairing mechanisms in the healing process. In this article, to investigate the temporal modoification of dermal collagen fiber in the burn wound healing, we used second-harmonic-generation (SHG) microscopy, showing high selectivity and good image contrast to collagen molecules as well as high spatial resolution, optical three-dimensional sectioning, minimal invasiveness, deep penetration, the absence of interference from background light, and in vivo measurement without additional staining. Since SHG light arises from a non-centrosymmetric triple helix of three polypeptide chains in the collagen molecule, SHG intensity sensitively reflects the structure maturity of collagen molecule and its aggregates. A series of time-lapse SHG images during the wound healing process of 2 weeks clearly indicated that condensation and melting of dermal collagen fibers by the deep dermal burn, decomposition of the damaged collagen fibers in the inflammation phase, production of new collagen fibers in the proliferation phase, and the growth of the new collagen fibers in the remodeling phase. These results show a high potential of SHG microscopy for optical assessment of the wound healing process in vivo.

Increased utilization of inorganic silver as an adjunctive to many medical devices has raised concerns of emergent silver resistance in clinical bacteria. Although the molecular basis for silver resistance has been previously characterized, to date, significant phenotypic expression of these genes in clinical settings is yet to be observed. Here, we identified the first strains of clinical bacteria expressing silver resistance at a level that could significantly impact wound care and the use ...

Conclusion: It seems Arnebia euchroma ointment to some extent reduced the extent of the wound especially in superficial burns compared to other dressings. However, it is better to conduct more similar studies with a larger sample size and different method and change in timing of dressing.
Results: The main finding of the current study described herein was the percent of isolates from burn wound (60%. The most common organism was pseudomonas (49%. Multidrug resistant gram negative organisms represent about 60% of the isolates. Pattern of antibiotic sensitivity was 84% for colistin, 39% for amikacin and 35% for imipenem. The mortalities in our study were 80%.
Full Text Available Silver sulfadiazine (SSD particles in homogeneous dispersion state were prepared by an ultrasonic method and then nano- and microparticles were separated using centrifugation. SSD particles with narrow size distribution were impregnated with bacterial cellulose (BC to produce BC–SSD composite membrane used as burn wound dressing. A scanning electron microscope (SEM was used to examine the surface morphology of BC–SSD membranes. The incorporation of SSD in BC–SSD was confirmed by X-ray diffraction (XRD. Antimicrobial tests in vitro indicated that BC–SSD showed excellent antibacterial activity against Staphylococcus aureus, Pseudomonas aeruginosa and Escherichia coli. The effects of BC–SSD on burn wound healing were assessed by rat models. The comparative study confirmed that the wound treated with BC–SSD showed high healing rate. The bacteria count in BC–SSD group was far less than control group. Histological analysis showed that epithelialization progressed better in wound treated with BC–SSD. These values demonstrated that the BC–SSD composite membrane could be a promising wound dressing for burn.

To update critical care practitioners on the recent advancements in burn care. Particular topics discussed include airway management, acute resuscitation, issues within the intensive care unit, nutrition, and wound management. This is a concise review of the recent burn literature tailored to the critical care practitioner. Criteria for extubation of burn patients are examined, as is the need for cuffed endotracheal tubes in pediatric burn patients. Strategies to avoid over-resuscitation are discussed, including use of colloid, as well as nurse-driven and computer-guided resuscitation protocols. New data regarding common ICU issues such as insulin therapy, delirium, and preferred intravenous access are reviewed. The importance of nutrition in the burn patient is emphasized, particularly early initiation of enteral nutrition, continuation of nutrition during surgical procedures, and use of adjuncts such as immunonutrition and beta blockade. Finally, both short-term and long-term wound issues are addressed via sections on laser Doppler assessment of burns and pressure garment therapy to prevent long-term scarring.

Intensive care and the surgical therapy of burn injuries have made significant advancements. The immediate care on the scene of the accident, however, is not uniform. There is no 'golden hour' which will decide the further clinical process. The acute estimate of the percentage of the extent of the burns is of little relevance and does not facilitate the admission to a burn unit. The emergency calculation of the volume of intravenous infusion is not advisable. The choice of transport has no discernible impact on the prognosis of the patient. Avoiding hypothermia and perceiving associated trauma can be of crucial prognostic importance in the pre-hospital care of burn patients. Detailed knowledge about the circumstances of the injury is of exceeding importance.

Full Text Available People with complex wounds are more likely to be elderly, living with multimorbidity and wound related symptoms. A variety of products are available for managing complex wounds and a range of healthcare professionals are involved in wound care, yet there is a lack of good evidence to guide practice and services. These factors create uncertainty for those who deliver and those who manage wound care. Formal priority setting for research and implementation topics is needed to more accurately target the gaps in treatment and services. We solicited practitioner and manager uncertainties in wound care and held a priority setting workshop to facilitate a collaborative approach to prioritising wound care-related uncertainties.We recruited healthcare professionals who regularly cared for patients with complex wounds, were wound care specialists or managed wound care services. Participants submitted up to five wound care uncertainties in consultation with their colleagues, via an on-line survey and attended a priority setting workshop. Submitted uncertainties were collated, sorted and categorised according professional group. On the day of the workshop, participants were divided into four groups depending on their profession. Uncertainties submitted by their professional group were viewed, discussed and amended, prior to the first of three individual voting rounds. Participants cast up to ten votes for the uncertainties they judged as being high priority. Continuing in the professional groups, the top 10 uncertainties from each group were displayed, and the process was repeated. Groups were then brought together for a plenary session in which the final priorities were individually scored on a scale of 0-10 by participants. Priorities were ranked and results presented. Nominal group technique was used for generating the final uncertainties, voting and discussions.Thirty-three participants attended the workshop comprising; 10 specialist nurses, 10 district
AIMS AND OBJECTIVES: The aim of this phenomenological study was to explore the emotions experienced by children\\'s nurses when caring for children with burns, in addition to ascertaining how the nurses dealt with these emotions. BACKGROUND: The nature of nursing practice is such that it inevitably generates some form of emotional response in nurses. The literature reveals that the manner nurses deal with their emotional experiences can impact on their nursing care. DESIGN: The study used Husserlian phenomenology to explore the emotional experiences of eight purposively selected children\\'s nurses who have worked on the burns unit of an Irish paediatric hospital. METHODS: Data were collected using in-depth, unstructured interviews and analysed using Colaizzi\\'s seven stage framework. RESULTS: The phenomenon of participants\\' emotional experiences is captured in four themes: (1) caring for children with burns, (2) supporting parents, (3) sustaining nurses\\' emotional well-being, and (4) learning to be a burns nurse. Nursing children with burns generated a myriad of emotions for participants. Burns dressing-changes, managing burn-related pain, supporting parents and the impact of busy workloads on the emotional care of children and their parents emerged as the most emotionally challenging aspects of participants\\' role. Participants recognised the need to manage their emotional responses and spoke of the benefits of a supportive nursing team. CONCLUSIONS: The findings offer insights into both the rewarding and challenging aspects of nursing children with burns. Nurses in this environment must be supported to recognise and manage their emotional responses to their work. RELEVANCE TO CLINICAL PRACTICE: Helping nurses to manage the emotional consequences of their work will help to sustain their emotional well-being, enhance the care received by children and also enable nurses to support parents in their role as partners in care.

The objective of this literature review is to describe graduating student nurses' and student podiatrists' wound care competence. This integrative literature review has been conducted with a systematic search process. Original studies were analysed by qualitative content analysis with the following stages: open coding, creating categories and abstraction. The literature search was conducted on May 2016 and reconducted on October 2016 using the Medline/Pubmed, CINAHL, Cochrane Library, Web of Science, Scopus and National Medic databases and 12 original studies were found. All the studies addressed graduating student nurses' wound care competence. According to original studies, graduating student nurses' wound care competence was inadequate. However, the students showed a positive attitude towards wound care. Subthemes of this literature review were: 1) Wound care knowledge, 2) Attitudes towards wound care, 3) Wound care preparedness and 4) Wound care education which created the main theme Graduating nurses' wound care competence. No studies were found about graduating student podiatrists' wound care competence. Graduating student nurses' wound care knowledge was deficient. Wound care education seemed to have a positive relation to students' wound care competence. The findings indicate that more information about graduating student nurses', and especially graduating podiatrists', wound care competence is needed. Copyright © 2017 Elsevier Ltd.

To establish the prevalence of wounds and their management in a community care setting. A multi-site, census point prevalence wound survey was conducted in the following areas: intellectual disability, psychiatry, GP practices, prisons, long-term care private nursing homes, long-term care, public nursing homes and the community/public health (district) nursing services on one randomly selected day. Acute services were excluded. Formal ethical approval was obtained. Data were collected using a pre-piloted questionnaire. Education was provided to nurses recording the tool (n=148). Descriptive statistical analysis was performed. A 97.2% response rate yielded a crude prevalence rate of 15.6% for wounds across nursing disciplines (290/1,854 total census) and 0.2% for the community area (290/133,562 population statistics for the study area). Crude point prevalence ranged from 2.7% in the prison services (7/262 total prison population surveyed) to 33.5% in the intellectual disability services (72/215 total intellectual disability population surveyed). The most frequent wounds recorded were pressure ulcers (crude point prevalence 4%, 76/1,854 total census; excluding category l crude point prevalence was 2.6%, 49/1,854 total census), leg ulcers (crude point prevalence 2.9%, 55/1,854 total census), self-inflicted superficial abrasions (crude point prevalence 2.2%, 41/1,854 total census) and surgical wounds (crude point prevalence 1.7%, 32/1,854 total census). These results support previous international research in that they identify a high prevalence of wounds in the community. The true community prevalence of wounds is arguably much higher, as this study identified only wounds known to the nursing services and excluded acute settings and was conducted on one day.
Full Text Available The in vivo antibacterial and burn wound healing potency of Persian shallot bulbs (Allium stipitatum were explored in a mice burn model infected with methicillin-resistant Staphylococcus aureus (MRSA. Hexane (ASHE and dichloromethane (ASDE extracts were tested. Female BALB/c mice were inflicted with third-degree thermal injury followed by infection with MRSA. ASHE and ASDE formulated with simple ointment base (SOB at concentrations of 1%, 2%, and 5% (w/w were topically applied to burn wounds twice a day for 20 days. Silver sulfadiazine (1% served as drug positive control. Microbiological analysis was carried out on 1, 2, 3, 4, and 5 days postwounding (dpw and histopathological analysis at the end of the experiment (20 dpw. Both ointments demonstrated strong antibacterial activity with complete elimination of MRSA at 48–72 h after infection. The rate of wound contraction was higher (95–100% in mice groups treated with ASHE and ASDE ointments after 15 dpw. Histological analysis revealed significant increase (p<0.05 in epithelialization and collagenation in treated groups. The ASHE and ASDE were found to be relatively noncytotoxic and safe to Vero cell line (383.4 μg mL−1; 390.6 μg mL−1, suggesting the extracts as safe topical antibacterial as well as promising alternatives in managing thermal injuries.

Various reagents have been applied in the treatment of skin chemical burns; however, no optimal reagent for skin chemical burns currently exists. The present study investigated the effect of topical body protective compound (BPC-157 treatment on skin wound healing, using an alkali burn rat model. Topical treatment with BPC-157 was shown to accelerate wound closure following an alkali burn. Histological examination of skin sections with hematoxylin–eosin and Masson staining showed better granulation tissue formation, reepithelialization, dermal remodeling, and a higher extent of collagen deposition when compared to the model control group on the 18th day postwounding. BPC-157 could promote vascular endothelial growth factor expression in wounded skin tissues. Furthermore, 3-(4,5-dimethylthiazol-2-yl-2,5-diphenyltetrazolium bromide and cell cycle analysis demonstrated that BPC-157 enhanced the proliferation of human umbilical vein endothelial cells (HUVECs. Transwell assay and wound healing assay showed that BPC-157 significantly promoted migration of HUVECs. We also observed that BPC-157 upregulated the expression of VEGF-a and accelerated vascular tube formation in vitro. Moreover, further studies suggested that BPC-157 regulated the phosphorylation level of

Impaired burn wound healing in the elderly represents a major clinical problem. Hypoxia-inducible factor-1 (HIF-1) is a transcriptional activator that orchestrates the cellular response to hypoxia. Its actions in dermal wounds promote angiogenesis and improve healing. In a murine burn wound model, aged mice had impaired wound healing associated with reduced levels of HIF-1. When gene therapy with HIF-1 alone did not correct these deficits, we explored the potential benefit of HIF-1 gene therapy combined with the intravenous infusion of bone marrow-derived angiogenic cells (BMDACs) cultured with dimethyloxalylglycine (DMOG). DMOG is known to reduce oxidative degradation of HIF-1. The mice treated with a plasmid DNA construct expressing a stabilized mutant form of HIF-1α (CA5-HIF-1α)+BMDACs had more rapid wound closure. By day 17, there were more mice with completely closed wounds in the treated group (χ(2), P=0.05). The dermal blood flow measured by laser Doppler showed significantly increased wound perfusion on day 11. Homing of BMDACs to the burn wound was dramatically enhanced by CA5-HIF-1α gene therapy. HIF-1α mRNA expression in the burn wound was increased after transfection with CA5-HIF-1α plasmid. Our findings offer insight into the pathophysiology of burns in the elderly and point to potential targets for developing new therapeutic strategies.
On Tuesday 22 November, the House of Lords (London, UK) held a short debate 'Improving the standard of wound care in the NHS.' It consisted of nine questions from the floor and a response from Lord O'Shaughnessy, The Parliamentary Under-Secretary of State for Health (Conservative). Here, Paul Browning, (Doctoral Research Student, University of Worcester, employed by 3M UK plc) summarises the key points from the evening and explains why it is so important we keep wound care on the Government's agenda.

The prevalence of chronic wounds is closely correlated to the aging population and so-called civilizational diseases. Therefore, they are causing morbidity and mortality of millions of patients worldwide, with an unbroken upward trend. As a consequence, chronic wounds induce enormous and rapidly growing costs for our health care systems and society in general. Thus, medically effective and cost-efficient treatment methods are urgently needed. Methods of 'regenerative medicine' might offer innovative scientific solutions, including the use of stem cells, growth factors and new bioactive materials. These tools are experimentally well described but clinically poorly performed. The main reasons for this are both legislative and economic. This review describes state-of-the-art techniques, up-to-date research projects, innovative preclinical and clinical approaches in wound care, and activities to translate these innovative techniques into clinical routine.

This aim of this ethnographic study is to understand a nursing staff's cultural perspectives throughout the care of a burned client in a burn unit. Data were collected through observation and interviews and interpreted in accordance with Bourdieu's perspective, that uses the habitus concepts and field to understand the behaviors that express what is internalized by people that belong to a social group. To carry out these dimensions of care, the professionals act in agreement with the forms that already internalized, and they expressed in their depositions: to suffer together, to act firmly, and at the same time, to be kind and affectionate.

We described a health care-associated Serratia marcescens outbreak of wound and soft tissue infection lasting approximately 11 months at Ankara University Ibni Sina Hospital. After identification of S marcescens strains from the clinical and environmental samples, and their susceptibility testing to antimicrobial agents, pulsed-field gel electrophoresis (PFGE) was performed to detect molecular epidemiologic relationships among these isolates. The strains which were isolated from the saline bottles used for wound cleansing in the wound care unit were found to be 100% interrelated by PFGE to the strains from the samples of the outbreak patients. Reuse of the emptied bottles has no longer been allowed since the outbreak occurred. Besides, more efficient and frequent infection control training for hospital staff has been conducted.

Objective: Use test methods to assess the oxygen compatibility of various wound care products. Approach: There are currently no standard test methods specifically for evaluating the oxygen compatibility and safety of materials under hyperbaric oxygen (HBO) conditions. However, tests such as the oxygen index (OI), oxygen exposure (OE), and autogenous ignition temperature (AIT) can provide useful information. Results: The OI test measures the minimum oxygen concentration that will support candle-like burning, and it was used to test 44 materials. All but two exhibited an OI equal to or greater (safer) than a control material commonly used in HBO. The OE test exposes each material to an oxygen-enriched atmosphere (>99.5% oxygen) to monitor temperature and pressure for an extended duration. The results of the OE testing indicated that none of the 44 articles tested with this method self-ignited within the 60°C, 3 atm pressurized oxygen atmosphere. The AIT test exposes materials to a rapid ramp up in temperature in HBO conditions at 3 atm until ignition occurs. Ten wound care materials and seven materials usually avoided in HBO chambers were tested. The AIT ranged from 138°C to 384°C for wound care products and from 146°C to 420°C for the other materials. Innovation: This work provides useful data and recommendations to help develop a new standard approach for evaluating the HBO compatibility of wound care products to ensure safety for patients and clinicians. Conclusion: The development of an additional test to measure the risk of electrostatic discharge of materials in HBO conditions is needed.

To explore the efficacies of treating patients with large area third-degree burns by tangential excision and skin grafting for subcutaneous tissue wounds. From January 2002 to December 2013, the medical records were retrospectively reviewed for 31 consecutive adult patients with a third-degree burn area exceeding 70% and undergoing tangential excision and skin grafting on subcutaneous tissue wound (TESGSTW) for the first time within 7 days postburn at Burn Center, Affiliated Jinan Central Hospital, Shandong University. For 31 patients, wounds with relative integrity eschar underwent TESGSTW by stages. Tourniquet was not used in some extremities. The relevant clinical data including patient condition on admission, causes of death, blood loss of tangential excision wound, surgical procedures and efficacies in cured group were analyzed. Average age, burn total area and third-degree burn area of 31 patients were (32.4 ± 12.8) years, (89.0 ± 6.2)% and (80.4 ± 7.6)% respectively. There were inhalation injury (n = 25, 80.6%) and early-stage shock before hospitalization (n = 22, 71.0%). Among 18 cured ones (58.1%), 2 patients had a third-degree burn area ≥ 90%. And 13 patients (41.9%) died and 10 of them died at 4 to 19 days postburn. Burn area was a risk factor of burn mortality. Sepsis and multiple organ dysfunction syndrome (MODS) were major mortality causes. Four patients died from early-stage sepsis. Within 14 days postburn, average blood loss volume per 1% tangential excision area in non-tourniquet group was slightly higher than that in the tourniquet group, but the difference was insignificant. For 18 cured patients, TESGSTW were performed 41 times. For 14 patients (77.8%), TESGSTW was performed twice. The average time of the first tangential excision was (4.1 ± 0.6) days postburn, the time interval between the first two tangential excisions was (6.4 ± 2.0) days, the first tangential excision area (33.8 ± 7.6)% and accumulated tangential excision area (58

To test the antimicrobial effectiveness of a silver alginate dressing on opportunistic pathogens, namely meticillin-sensitive Staphylococcus aureus (MSSA) and meticillin-resistant Staphylococcus aureus (MRSA), Klebsiella spp., Enterococcus faecalis, Enterococcus faecium, Pseudomonas aeruginosa, Escherichia coli, Enterobacter sakazakii, Enterobacter cloacae, Serratia marcescens, Chryseobacterium indologenes, Proteus vulgaris and Acinetobacter baumannii. In total, 40 microorganisms were isolated from patients attending three burn centres in the US and evaluated for their susceptibility to a silver alginate wound dressing, employing a corrected zone of inhibition assay, conducted on Mueller Hinton agar (MHA). The sizes of the corrected zones of inhibition varied between and within genera. For example, all Acinetobacter baumannii strains were found to be sensitive to ionic silver at pH 7, with a mean of 2.8mm, compared with 3.5mm at pH 5.5. The silver alginate dressing also demonstrated activity on all strains of Enterobacter and Escherichia coli, with susceptibility to the silver alginate dressing enhanced at pH 5.5. For Enterococcus spp. the average corrected zone of inhibition at pH 7 was 3.6mm, versus 4.9mm at pH 5.5. All strains of Pseudomonas aeruginosa were found to be sensitive to the silver alginate dressing. The average corrected zone of inhibition was 6.9mm at pH 7, compared with 8mm at pH 5.5. For MRSA and Staphylococcus aureus, it ranged from 4.5mm to 7.5mm at pH 7. When the pH was decreased to 5.5, the corrected zone of inhibition increased. This study demonstrates the activity of a silver alginate dressing on a wide range of burn isolates, including antibiotic-resistant bacteria, isolated from three different burn centres in the US. It also highlights the possible importance of pH and its potential effects on antimicrobial performance and microbial susceptibility. However, more extensive testing is required to substantiate this.

Adequate assessment of burn wounds is crucial in the management of burn patients. Thermography, as a noninvasive measurement tool, can be utilized to detect the remaining perfusion over large burn wound areas by measuring temperature, thereby reflecting the healing potential (HP) (i.e., number of days that burns require to heal). The objective of this study was to evaluate the clinimetric properties (i.e., reliability and validity) of thermography for measuring burn wound HP. To evaluate reliability, two independent observers performed a thermography measurement of 50 burns. The intraclass correlation coefficient (ICC), the standard error of measurement (SEM), and the limits of agreement (LoA) were calculated. To assess validity, temperature differences between burned and nonburned skin (ΔT) were compared to the HP found by laser Doppler imaging (serving as the reference standard). By applying a visual method, one ΔT cutoff point was identified to differentiate between burns requiring conservative versus surgical treatment. The ICC was 0.99, expressing an excellent correlation between two measurements. The SEM was calculated at 0.22°C, the LoA at -0.58°C and 0.64°C. The ΔT cutoff point was -0.07°C (sensitivity 80% specificity 80%). These results show that thermography is a reliable and valid technique in the assessment of burn wound HP.

Purpose To evaluate the effects of dry eye on ocular surface protease activity and sight threatening corneal complications following ocular surface chemical injury. Methods C57BL/6 mice were subjected to unilateral alkali burn (AB) with or without concomitant dry eye for 2 or 5 days. Mice were observed daily for appearance of corneal perforation. Whole corneas were harvested and lysed for RNA extraction. Quantitative real-time PCR was performed to measure expression of inflammation cytokines, matrix metalloproteinases (MMP). Matrix metalloproteinase–9 activity, gelatinase activity, and myeloperoxidase (MPO) activity were evaluated in corneal lysates. Presence of infiltrating neutrophils was evaluated by immunohistochemistry and flow cytometry. Results Eyes subjected to the combined model of AB and dry eye (CM) had 20% sterile corneal perforation rate as soon as 1 day after the initial injury, which increased to 35% by 5 days, delayed wound closure and increased corneal opacity. Increased levels of IL-1β, -6, and MMPs-1, -3, -8, -9, and -13, and chemokine (C-X-C motif) ligand 1 (CSCL1) transcripts were found after 2 days in CM compared with AB corneas. Increased MMP-1, -3, -9, and -13 immunoreactivity and gelatinolytic activity were seen in CM corneas compared with AB. Increased neutrophil infiltration and MPO activity was noted in the CM group compared with AB 2 days post injury. Conclusions Desiccating stress worsens outcome of ocular AB, creating a cytokine and protease storm with greater neutrophil infiltration, increasing the risk of corneal perforation. PMID:26225631
Full Text Available Introduction. Given its efficacy and safety, NexoBrid™ (NXB has become part of our therapeutic options in burns treatment with satisfactory results. However, no cost analysis comparing NXB to the standard of care (SOC has been carried out as of today. Aim. To assess the cost of treatment with NXB and compare it to the SOC cost. Methods. 20 patients with 14–22% of TBSA with an intermediate-deep thermal burn related injury were retrospectively and consecutively included. 10 of these patients were treated with the SOC, while the other 10 with NXB. The cost analysis was performed in accordance with the weighted average Italian Health Ministry DRGs and with Conferenza Stato/Regioni 2003 and the study by Tan et al. For each cost, 95% confidence intervals have been evaluated. Results. Considering the 10 patients treated with NXB, the overall savings (total net saving amounted to 53300 euros. The confidence interval analysis confirmed the savings. Discussion. As shown by our preliminary results, significant savings are obtained with the use of NXB. The limit of our study is that it is based on Italian health care costs and assesses a relative small cohort of patients. Further studies on larger multinational cohorts are warranted.

The present controlled study assessed the systemic effect of 830-nm LED phototherapy in rodent models. Two HR-1 hairless mice and 3 HWY/Slc hairless rats were divided into two groups: the treatment group (Tx Group, one mouse, two rats) and the control group (Con Group, one mouse, one rat). All animals received an identical 12 mm × 12 mm control burn over three sites on the dorsum with a fractional ablative CO(2) laser. Wounds were protected with a film-type dressing. The abdomen of the Tx Group subjects was irradiated with an 830-nm LED array immediately post CO(2) treatment and then at 1, 5 and 6 days post laser irradiation. Wound healing was assessed macroscopically from the clinical photography. At the 2-day post-laser assessment, the healing process in the wounds in the Tx Group was already apparent compared with the Con Group. At the final evaluation (post-burn day 7), no site on the Con Group (six wounds) showed 100% healing, recovery was over 70% in four and lower than 50% in two sites. Of the nine Tx Group sites, 100% recovery was seen in three sites, over 70% in five sites and one wound was exacerbated through trauma. LED phototherapy on the abdomen produced faster wound healing of the uniform burn wounds than in animals with the same burn wounds that did not receive LED phototherapy, strongly suggesting the systemic effect of phototherapy.

As restoration of the integument is paramount to wound healing, dermatologists should be central to managing wounds; yet this is often not the case. If a training gap exists during residency training, this may account for the observed discrepancy. To identify United States (US) dermatology residents' impressions regarding their preparedness to care for wounds, and to assess the amount and type of training devoted to wound care during residency. An online survey among current US dermatology residents enrolled in a residency training program. The primary goal was to determine whether dermatology residents believe more wound care education is needed, evaluate preparedness to care for wounds, and identify future plans to manage wounds. Responses were received from 175 of 517 (33.8%) US Dermatology residents contacted. The majority of residents did not feel prepared to manage acute (78.3%) and chronic (84.6%) wounds. Over three quarters (77.1%) felt that more education is needed. Fewer than half (49.1% and 35.4%) of residents planned to care for acute and chronic wounds, respectively, when in practice. There is a gap in wound care education in US dermatology residency training. This translates to a low percentage of dermatology residents planning to care for wounds in future practice. Dermatology residents need to receive focused wound care training in order to translate the underpinnings of wound healing biology and ultimately better serve patients.

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

Complex wounds such as leg and foot ulcers are common, resource intensive and have negative impacts on patients' wellbeing. Evidence-based decision-making, substantiated by high quality evidence such as from systematic reviews, is widely advocated for improving patient care and healthcare efficiency. Consequently, we set out to classify and map the extent to which up-to-date systematic reviews containing robust evidence exist for wound care uncertainties prioritised by community-based healthcare professionals. We asked healthcare professionals to prioritise uncertainties based on complex wound care decisions, and then classified 28 uncertainties according to the type and level of decision. For each uncertainty, we searched for relevant systematic reviews. Two independent reviewers screened abstracts and full texts of reviews against the following criteria: meeting an a priori definition of a systematic review, sufficiently addressing the uncertainty, published during or after 2012, and identifying high quality research evidence. The most common uncertainty type was 'interventions' 24/28 (85%); the majority concerned wound level decisions 15/28 (53%) however, service delivery level decisions (10/28) were given highest priority. Overall, we found 162 potentially relevant reviews of which 57 (35%) were not systematic reviews. Of 106 systematic reviews, only 28 were relevant to an uncertainty and 18 of these were published within the preceding five years; none identified high quality research evidence. Despite the growing volume of published primary research, healthcare professionals delivering wound care have important clinical uncertainties which are not addressed by up-to-date systematic reviews containing high certainty evidence. These are high priority topics requiring new research and systematic reviews which are regularly updated. To reduce clinical and research waste, we recommend systematic reviewers and researchers make greater efforts to ensure that research

Studies comparing contemporary silver dressings in burns are scarce. In a prospective, randomized, controlled study, counting 50 patients/research group, we compared two frequently used silver dressings, Acticoat™ and Aquacel(®) Ag, in the management of partial thickness burns with a predicted healing time between 7 and 21 days as assessed by laser Doppler imaging between 48 and 72h after burn. Variables investigated were related to baseline research group characteristics, wound healing, bacteriology, economics, nurse, and patient experience. Both research groups were comparably composed taking into account gender, age and burn characteristics. Similar results were obtained as to healing time and bacterial control with both silver dressings. A statistically significant difference in favor of the Aquacel(®) Ag dressing was found for average ease of use (p<0.001), average ease of application (p=0.001), patient pain (p<0.001), patient comfort with the dressing (p=0.017), silver staining (p<0.001), and cost effectiveness (p<0.001). Both silver dressings resulted in comparable healing times and bacterial control but the Aquacel(®) Ag dressing significantly increased comfort for patients as well as nurses and was significantly more cost-effective than the Acticoat™ dressing for the given indication.

Summary Application of cell therapies in burn care started in the early 80s in specialized hospital centers world-wide. Since 2007, cell therapies have been considered as “Advanced Therapy Medicinal Products” (ATMP), so classified by European Directives along with associated Regulations by the European Parliament. Consequently, regulatory changes have transformed the standard linear clinical care pathway into a more complex one. It is important to ensure the safety of cellular therapies used for burn patients and to standardize as much as possible the cell sources and products developed using cell culture procedures. However, we can definitely affirm that concentrating the bulk of energy and resources on the implementation of Good Manufacturing Practice (GMP) alone will have a major negative impact on the care of severely burned patients world-wide. Developing fully accredited infrastructures and training personnel (required by the new directives), along with obtaining approval for clinical trials to go ahead, can be a lengthy process.We discuss whether or not these patients could benefit from cell therapies provided by standard in-hospital laboratories, thus avoiding having to meet rigid regulations concerning the use of industrial pharmaceutical products. “Hospital Exemption” could be a preferred means to offer burn patients a customized and safe product, as many adaptations may be required throughout their treatment pathway. Patients who are in need of rapid treatment will be the ones to suffer the most from regulations intended to help them. PMID:28149232
This study aimed to establish the prevalence and aetiology of wounds, allowing an insight into the management of wound care, the use of dressings and the nursing time allocated to the provision of wound care in a community setting in Ireland. A cross-sectional survey was used, with data collected on all clients in the community who received treatment from public health nurses or community registered general nurses for wound care over a 1-week period in April 2013. A 98.9% response rate was realised, and 188 people were identified as having wounds, equating to a crude prevalence of 5% of the active community nursing caseload. A total of 60% (n=112) had leg ulcers, 22% (n=42) had pressure ulcers, 16% (n=30) had an acute wound (surgical or traumatic wounds), 1% (n=2) had a diabetic foot wound and a further 1% (n=2) had wounds of other aetiologies. The mean duration of wounds was 5.41 months. A total of 18% of wounds were identified as infected; however, 60% (n=112) of wounds had antimicrobial products in use as either a primary or secondary dressing. The study established that there is a significant prevalence of wounds in this community care area. There was absence of a clinical diagnosis in many cases, and evidence of inappropriate dressing use, risking an increase in costs and a decrease in good clinical outcomes. It also highlighted the importance of ongoing education and auditing in the provision of wound care.

Classic determinants of burn mortality are age, burn size, and the presence of inhalation injury. Our objective was to describe temporal trends in patient and burn characteristics, inpatient mortality, and the relationship between these characteristics and inpatient mortality over time. All patients aged 18 years or older and admitted with burn injury, including inhalation injury only, between 2004 and 2013 were included. Adjusted Cox proportional hazards regression models were used to estimate the relationship between admit year and inpatient mortality. A total of 5540 patients were admitted between 2004 and 2013. Significant differences in sex, race/ethnicity, burn mechanisms, TBSA, inhalation injury, and inpatient mortality were observed across calendar years. Patients admitted between 2011 and 2013 were more likely to be women, non-Hispanic Caucasian, with smaller burn size, and less likely to have an inhalation injury, in comparison with patients admitted from 2004 to 2010. After controlling for patient demographics, burn mechanisms, and differential lengths of stay, no calendar year trends in inpatient mortality were detected. However, a significant decrease in inpatient mortality was observed among patients with extensive burns (≥75% TBSA) in more recent calendar years. This large, tertiary care referral burn center has maintained low inpatient mortality rates among burn patients over the past 10 years. While observed decreases in mortality during this time are largely due to changes in patient and burn characteristics, survival among patients with extensive burns has improved.
What does it mean to offer care when the act of caring is wounding to its giver? For peer specialists-individuals with lived experience as patients in the psychiatric system-this question shapes how they use their own histories to provide support for individuals experiencing psychiatric crisis. Peer support is unique in the way it draws on empathetic resonance and depends on carefully deployed vulnerability; where one connects with others through the recognition of shared experience and mutual hurt. For peers, care works when this guidance, reassurance, and "being with"-all of which draw upon their own stories of traumatic history and variegated suffering-mitigate the present crisis being experienced by another. Drawing on twenty-eight months of fieldwork with a peer-staffed crisis respite center in the eastern United States, I argue that the peer specialist becomes the embodiment of a novel intersection of intimacy and compensation; one that poses vulnerability not as a consequence, casualty, or risk factor in the commodification of care, but as its principle vector of resonance and the assumption on which it is based. For peers, care that works-in that it creates a mutual resonance for the recipient-becomes simultaneously care that wounds its giver.

Mimicking skin extracellular matrix hierarchy, the present work aims to develop a bilayer skin graft comprising a porous cotton-wool-like 3D layer with membranous structure of PCL-chitosan nanofibers. Emulsion electrospinning with differential stirring periods of PCL-chitosan emulsion results in development of a bilayer 3D structure with varied morphology. The electrospun membrane has fiber diameter ∼274 nm and pore size ∼1.16 μm while fluffy 3D layer has fiber diameter ∼1.62 μm and pore size ∼62 μm. The 3D layer was further coated with collagen I isolated from Cirrhinus cirrhosus fish scales to improve biofunctionality. Surface coating with collagen I resulted in bundling the fibers together, thereby increasing their average diameter to 2.80 μm and decreasing pore size to ∼45 μm. The architecture and composition of the scaffold promotes efficient cellular activity where interconnected porosity with ECM resembling collagen I coating assists cellular adhesion, infiltration, and proliferation from initial days of fibroblast seeding, while keratinocytes migrate on the surface only without infiltrating in the membranous nanofiber layer. Anatomy of the scaffold arising due to variation in pore size distribution at different layers thereby facilitates compartmentalization and prevents initial cellular transmigration. The scaffold also assists in extracellular matrix protein synthesis and keratinocyte stratification in vitro. Further, the scaffold effectively integrates and attaches with third-degree burn wound margins created in rat models and accelerates healing in comparison to standard Tegaderm dressing™. The bilayer scaffold is thus a promising, readily available, cost-effective, off-the-shelf matrix as a skin substitute.

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

Conclusions: Olea ointment is a useful treatment for burns, and it can prevent infections, accelerate tissue repair, and facilitate debridement. Therefore, using this ointment is recommended for the treatment of burns.
Full Text Available Background: Toxic shock syndrome (TSS, a dangerous consequence of Toxic shock syndrome toxin-1 (TSST-1 caused by Staphylococcus aureus. The early detection for infections of Staphylococcus aureus in burned children is very important, also the pre-vention for consequences of TSST-1. Fever is one of the most noticeable sign in burned children. On the other hand, fever is one of the important consequences of TSST-1 pro-duction. Methods: This study aimed to assess the toxic shock syndrome toxin-1 level in the wound’s specimens of two groups febrile and afebrile in the hospitalized burned chil-dren in Motahari hospital Tehran, Iran in the year 2013. In this case-control study, 90 children who admitted to the burn unit, divided in two groups of 45 patients: febrile (cases group and afebrile (control group. All of burned children under went wound biopsy, and then all of wound’s specimens were tested by PCR for specific primer of toxin producing genome. Finally all of data collected and statistically analyzed. This data include group febrile and afebrile, demographic characteristics, percentage of burned surface severity and result of PCR. Results: The positive result for PCR test, production of TSST-1 in febrile burned chil-dren (cases group was 37.7% and in afebrile burned children (control group was 11.1% that this different was statistically significant (P=0.003. The mean and stan-dard deviation for percentage of burned surface (severity in samples with positive re-sult for PCR test was 30.9±16.93 and in samples with negative result for PCR test was 20.09±11.02 that this different was statistically significant (P=0.01. There was no dif-ference between positive PCR result and negative PCR result of age and sex. Conclusion: Direct association was approved between the production of TSST-1 and the occurrence of fever in burned children. Increased surface severity of burns also re-lated to the production of TSST-1. Further research is recommended.

The aim of this study was to validate a set of previously developed criteria for wound care documentation and to use the validated criteria as a framework for developing a wound care documentation model. The Skin Integrity component of the Finnish Care Classification, the Finnish Classification of Nursing Diagnosis, and the Finnish Classification of Nursing Interventions serve as the basis for the wound care documentation model. Finnish wound care specialists, mainly nurses, from different Finnish hospitals, and from the Finnish Wound Care Society having on average 18 years of experience in wound management. Data were collected using electronic survey technology. A Delphi technique was used to develop and validate the documentation system. The final model consists of 7 main categories and 25 subcategories of the Skin Integrity component of the Finnish Classification of Nursing Diagnosis and 5 main categories and 25 subcategories of the Skin Integrity component of the Finnish Classification of Nursing Intervention. Based on the results of the Delphi survey, consensus was reached on all elements of the wound care documentation model. The Delphi process was used to develop a wound care documentation model for use in an electronic record to promote systematic documentation of both wound assessment and wound care. Future research should address the utility of this documentation model for nurses with expertise in wound care and generalist nurses.

Multi-drug resistant Pseudomonas aeruginosa has increased progressively and impedes further regression in mortality in burn patients. Such wound infections serve as bacterial reservoir for nosocomial infections and are associated with significant morbidity and costs. Anti-microbial polycationic dendrimers G3KL and G3RL, able to kill multi-drug resistant P. aeruginosa, have been previously developed. The combination of these dendrimers with a class of biological bandages made of progenitor skin cells, which secrete growth factors, could positively impact wound-healing processes. However, polycations are known to be used as anti-angiogenic agents for tumor suppression. Since, neovascularization is pivotal in the healing of deep burn-wounds, the use of anti-microbial dendrimers may thus hinder the healing processes. Surprisingly, we have seen in this study that G3KL and G3RL dendrimers can have angiogenic effects. Moreover, we have shown that a dendrimer concentration ranging between 50 and 100 μg/mL in combination with the biological bandages can suppress bacterial growth without altering cell viability up to 5 days. These results show that antimicrobial dendrimers can be used in combination with biological bandages and could potentially improve the healing process with an enhanced angiogenesis.
Full Text Available Pseudomonas aeruginosa, a ubiquitous opportunistic pathogen, is the most common infective agent of burn wounds. The aim of this study was to compare the histopathological effect of a mixture of aqueous extract of cinnamon and honey with silver sulfadiazine on the healing of Pseudomonas aeruginosa infected second grade skin burn wounds in rats. To this end, 60 male rats were randomly assigned to four experimental groups (15 rats in each group. After inducing anesthesia, second grade burn wound with the diameter of 12 mm was created in the dorsal region of rats. Then, 1.5×108 cfu/ml P. aeruginosa PA01was equally bestrewed on the wound of all rats. Every 12 hours, silver sulfadiazine (group 1, honey (group 2 and aqueous extract of cinnamon and honey (group 3 were applied to the wounds and group 4 was kept as control. On days 7, 14, and 21, five rats were selected from each group at each time point and after inducing anesthesia and measuring the diameter of the wound by coliseum, microbial and histopathological samples were taken from the wounds. Microbial studies showed that in all groups except the control group, the growth of the microbe was stopped. Histopathological observations regarding wound healing and diameter showed that there was a significant difference between treatment groups and the control group on days 7, 14 and 21 (p

Despite dramatic improvements in the management of burns, infection still remains a serious risk for the burn patient. The aim of this study was to shed light on the impact of acute burn injury with or without infection on cytokine profiles. Sprague-Dawley rats (n = 21) were randomized into three groups: 1) burn only 2) burn and infection or 3) sham burn. Weight was monitored and blood was collected for cytokine ELISA, LPS quantification, and peripheral blood analysis. Animals were sacrificed either after 6 or 12 days. Infected animals showed substantial weight loss until day 6 post-burn as compared to burn alone. Endotoxin and TNF-alpha levels were elevated early in the infected burn group within 48 hours post-burn. In contrast, significant up-regulation of the anti-inflammatory cytokine IL-10 occurred later in the clinical course and was associated with the recovery from weight loss. Our results suggest that in the presence of infection, you get a SIRS response possibly due to transient endotoxemia that is only seen in the infection group. In contrast, both burn and infection get a late IL-10 (CARS) response, which is then associated with a return to normal weight in the infection group.

Introduction: Non-invasive monitoring of wound healing is warranted. Opticalcoherence tomography (OCT) enables instant visualization of the epidermis andupper dermis. We have studied the healing of uniform epidermal wounds inhumans using OCT. Methods: Thirty-two, 16 females and 16 males, non......-smoking healthy volunteers aged18 –49 yea rs were enrolled (NCT02116725). Suction blisters were raised on each but-tock by applying chambers with a 10 mm opening at 2380 mmHg and surface tem-perature of 408C. The blister roofs comprising the entire epidermis were excised. The60 wounds were scanned by OCT on day 0...... (baseline), and post-wounding days 2 and4. Full-thickness skin biopsies (12 mm 3 3 mm) of the 60 wounds were excised andprocessed for routine histology. In two volunteers, wound healing was followed over14 days by OCT and transepidermal water loss. Data were analyzed in linear mixedmod els for repeated...
Full Text Available Advanced wound care centres are now a well established response to the growing epidemic of chronic wounds in the adult population. Is the concept transferable to children? Whilst there is not the same prevalence of chronic wounds in children there are conditions affecting the integumentary system that do have a profound effect on the quality of life of both children and their families. We have identified conditions involving the skin, scars and wounds which contribute to a critical number of potential patients that can justify the setting up of an advanced skin, scar and wound care centre for children. The management of conditions such as giant naevi, extensive scarring and epidermolysis bullosa challenge medical professionals and lead to new and novel treatments to be developed. The variation between and within such conditions calls for a customizing of individual patient care that involves a close relationship between research scientists and clinicians. This is translational medicine of its best and we predict that this is the future of wound care particularly and specifically in children.

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

Skin burn is one of the most common complications and remains a major public health issue worldwide. This experiment was conducted to study the effects of traditional medicine (Visceral Fat and Barely Seed Ash) compared with silversulfadiazine (SSD) cream on healing burn wounds in rats. Sixty adult male Wistar rats were randomly divided into four groups of equal numbers; each group consisted of 15 animals. After sedation, type II of skin burn with 1.5 cm diameter circle was created on the back of rats with a heated metal in boiling water. Group one was not treated and considered as control. The burned areas in the second, third and fourth groups were applied twice a day with normal saline, SSD cream and traditional preparation, respectively. Percentage of the burn wound concentration and histopathological examinations were used as parameters of our study on days 4, 9and 14. Obtained data were compared between the groups and days. SSD cream and traditional preparation had better effects on burnt wound healing compared with control group. Furthermore, on the final day of study, the average percentage of wound concentration in traditional medicine group was significantly greater than other groups (P < 0.05). This finding was supported and confirmed by histological examination as well. Traditional preparation significantly decreased inflammation and accelerated wound healing in treated rats. Furthermore, the findings of this study can be applied clinically in the future.

Patients with burn wounds are susceptible to wound infection and sepsis. This research introduces a novel burn wound dressing that contains silver nanoparticles (SNPs) to treat infection in a 2-acrylamido-2-methylpropane sulfonic acid sodium salt (AMPS-Na(+) ) hydrogel. Silver nitrate was dissolved in AMPS-Na(+) solution and then exposed to gamma irradiation to form SNP-infused hydrogels. The gamma irradiation results in a cross-linked polymeric network of sterile hydrogel dressing and a reduction of silver ions to form SNPs infused in the hydrogel in a one-step process. About 80% of the total silver was released from the hydrogels after 72 h immersion in simulated body fluid solution; therefore, they could be used on wounds for up to 3 days. All the hydrogels were found to be nontoxic to normal human dermal fibroblast cells. The silver-loaded hydrogels had good inhibitory action against Pseudomonas aeruginosa and methicillin-resistant Staphylococcus aureus. Results from a pilot study on a porcine burn model showed that the 5-mM silver hydrogel was efficient at preventing bacterial colonization of wounds, and the results were comparable to the commercially available silver dressings (Acticoat(TM) , PolyMem Silver(®) ). These results support its use as a potential burn wound dressing. © 2014 Wiley Periodicals, Inc. and the American Pharmacists Association.

To evaluate the clinical curative effect of applying vacuum sealing drainage (VSD) therapy in treating deep partial-thickness burn wound at the initial stage prospectively, and to provide the basis for its clinical application. Twenty-two patients with about 10% TBSA burn of the lower limbs, and in which partial-thickness wound exceeded 1% TBSA in each limb, were admitted to our hospital within 3 hours after burn from May 2009 to March 2010. Wounds in each patient were divided into VSD treatment group (treated with VSD therapy) and control group (treated with 10 g/L silver sulfadiazine cream) based on the principles of symmetry of location, identical deepness, and similarity in size etc. The amount of water evaporation, the swelling intensity, the status of bacterial colonization, the degree of pain, the healing time, and the quality of healing of wounds in 2 groups were observed and compared. Data were processed with t test and rank-sum test. The observation was completed in 21 patients. All of the wounds were treated within 4 hours post burn (PBH). The amount of water evaporation of the normal skin and burn wounds before dressing coverage in VSD treatment group was respectively close to that in control group (with t value respectively 1.310, -0.911, P values all above 0.05); the amount of water evaporation on the surface of dressing in VSD treatment group [(44.3+/-3.9) mLxh(-1)xm(-2)] was less than that in control group [(66.1+/-6.4) mLxh(-1)xm(-2), t=-11.39, P0.05). The healing quality of wounds in VSD treatment group (100.00%, 100.00%) 2 or 3 months after burn was better than that in control group (19.05%, 85.71%) (with Z value respectively -11.638, -3.870, P values all below 0.01). Early application of VSD therapy cannot expedite the healing process of deep partial-thickness burn wounds, but it can improve the healing quality. It is one of the effective methods to deal with deep partial-thickness burn wounds, which is worthy of clinical attention and further

MRSA is the predominant pathogen responsible for fatal burn wound infection in patients. Antibiotic resistance and its ability to form biofilms on the surface of burn wounds limit the use of antibiotics to contain this pathogen. The results of present study have shown that single dose of combination therapy of endolysin MR-10 (50μg/s.c) and minocycline (50mg/kg/orally) resulted in 100% survival of group of mice with systemic MRSA infection. Maximum reduction in bacterial load in various organs was observed in the group that received combination therapy. In comparison to control, a significant reduction (pendolysin MR-10 and minocycline is a better option in controlling burn wound infections. Copyright Â© 2016 Elsevier GmbH. All rights reserved.

Pseudomonas aeruginosa is often implicated in burn wound infections; its inherent drug resistance often renders these infections extremely challenging to treat. This is further compounded by the problem of emerging drug resistance and the dearth of novel antimicrobial drug discovery in recent years. In the perennial search for effective antimicrobial compounds, the authors identify short synthetic β-sheet folding peptides, IRIKIRIK (IK8L), IRIkIrIK (IK8-2D), and irikirik (IK8D) as prime candidates owing to their high potency against Gram-negative bacteria. In this study, the peptides are first assayed against 20 clinically isolated multidrug-resistant P. aeruginosa strains in comparison with the conventional antibiotics imipenem and ceftazidime, and IK8L is demonstrated to be the most effective. IK8L also exhibits superior antibacterial killing kinetics compared to imipenem and ceftazidime. From transmission electron microscopy, confocal microscopy, and protein release analyses, IK8L shows membrane-lytic antimicrobial mechanism. Repeated use of IK8L does not induce drug resistance, while the bacteria develop resistance against the antibiotics after several times of treatment at sublethal doses. Analysis of mouse blood serum chemistry reveals that peptide does not induce systemic toxicity. The potential utility of IK8L in the in vivo treatment of P. aeruginosa-infected burn wounds is further demonstrated in a mouse model. © 2017 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

Silver nanoparticles (AgNPs) are promising antimicrobial agents for treatment of wounds and burns. We synthesized AgNPs using honey at different pH values or with different gamma irradiation doses. The resulting nanoparticles were characterized by UV-vis spectroscopy, TEM, DLS and FTIR. Their antimicrobial activity, against standard bacterial strains and silver-resistant clinical isolates from infected wounds and burns, was evaluated in vitro through determination of their minimum inhibitory concentration (MIC). AgNPs prepared using 30 g of honey exposed to 5 kGy gamma radiation had the best physical characters regarding stability and uniformity of particle size and shape. They recorded the lowest MIC values against both the standard and silver-resistant isolates. In conclusion, honey and gamma radiation can be used in synthesis of highly stable pure AgNPs, without affecting the physico-chemical and antimicrobial activity of honey. This offered an advantage in terms of inhibition of silver-resistant bacteria isolates.

Background and Objective: Two thirds of all accidents and injuries leading to death all around the world occur in developing countries like Iran. One of these accidents is burn that can have unpleasant effects on the individual's body and soul. Skin wound healing is a process that happens as a result of coordination between tissues, cells, and different factors. The remaining inflammation and insufficient amount of vessel construction are among the most important causes of delayed wound healing. In recent years, jujube fruit (Zizyphus vulgaris L.) has been reported to have anti-inflammatory effects as a traditional therapeutic agent. Therefore, the present study was conducted in order to investigate the effects of jujube fruit extract on second-degree burn wound among Balb/c mice. Materials and Methods: The present empirical-interventional study included 48 Balb/c mice weighing approximately 30 +/- 3 gr. After burn wounds of 1.5 cm2 were created and second-degree burns was affirmed by a pathologist, the mice were divided into four control groups; one treated with Vaseline, one treated with silver sulfadiazine ointment, one treated with jujube fruit extract 1%, and a control group. Results: In treatment groups, 1 gr ointment containing hydroalcoholic extract of jujube fruit was utilized twice a day until complete recovery. Afterwards, the four groups were compared with regard to the wound area and histopathology. The collected data were analyzed through one-way ANOVA and Tukey tests by using SPSS software. Conclusion: There was a significant difference between the intervention group and the Vaseline and control groups with regard to the percentage of wound recovery (P smaller than 0.05). The results of the study indicated that the jujube fruit extract could accelerate burn wound healing among Balb/c mice. It is recommended that further research is conducted on the effects of different doses of this medicine on laboratory animals and then on humans.

Many months after the devastating earthquake in January 2010, wounds remain a major disease burden in Haiti. Since January 2010, through the efforts of corporations, nonprofit charitable organizations, and medical professionals, advanced wound care techniques, including negative-pressure wound therapy (NPWT), have been introduced into the wound care regimens of various hospitals in Haiti. In June 2010, the authors completed their second volunteer trip at a Haitian hospital specializing in orthopedic wounds. The medical team was composed of a plastic surgeon, orthopedic surgeon, anesthesiologist, medical assistant, scrub technician, and registered nurse (specializing in plastic surgery and orthopedics). The authors' team supplied NPWT devices, reticulated open-cell foam dressings, and canisters donated by Kinetic Concepts, Inc, San Antonio, Texas, for use at the hospital. This report describes the medical challenges in postearthquake Haiti (including limb salvage and infection), benefits of adjunctive use of NPWT/reticulated open-cell foam, and current wound care status in a Haitian orthopedic hospital. The future role of NPWT in Haiti and during mass catastrophe in a least-developed country is also discussed.

In wound care, close observation of the quantity and nature of exudate from a wound, and selection of appropriate dressing and/or medication are crucial. Care should be taken to prevent wounds with excessive exudate from becoming too moist. Furthermore, wound care at home must be easy, which is achievable through the use of readily available materials and medications. 1 ) A wound with little to moderate exudate should be treated using wrap therapy with perforated polyethylene sheets. This therapy can be used to treat pressure ulcers, wounds, wounds with slough, and burns. 2 ) An 18-gauge needle can be used to perforate wounds with little exudate, such as mild pressure ulcers or wounds with slough, and polyurethane film can then be applied. 3 ) Polyurethane film should be applied to blisters, pressure ulcers, or similar skin injuries with little exudate. 4 ) A hydrocolloid dressing should be used on wounds with light exudate. 5 ) An ointment containing steroids should be applied to critically colonized wounds. 6 ) Melolin dressings, Moiskin Pads, or a disposable diaper should be used to manage wounds with heavy exudate.

Objective: To investigate the effects of flow-through descending branch of lateral circumflex femoral artery flap on repairing high-voltage electrical burn wounds of wrist of patients. Methods: From January 2014 to June 2016, 5 patients with high-voltage electrical burn of unilateral wrist were hospitalized in our burn ward, with extensive necrosis of skin soft tissue of burn wrist. Five patients were transferred to our burn ward 6 to 12 days post injury after undergoing emergency dermotomy of wrist to reduce tension in other hospitals. In 2 to 3 days after admission, operation was performed by two surgeon group at the same time, when patients' general condition were stable. One group underwent debridement and the other group designed and dissected flap according to the range of skin soft tissue defect of wrist. Wrist wounds after debridement ranged from 15 cm×10 cm to 24 cm×15 cm. Three patients were treated with flow-through descending branch of lateral circumflex femoral artery flap and great saphenous vein for repairing wounds of wrist and reconstruction of ulnar and radial artery. Two patients were treated with flow-through descending branch of lateral circumflex femoral artery flap for repairing wounds of wrist and reconstruction of ulnar artery. The dissected flaps ranged from 16 cm×12 cm to 26 cm×16 cm and the length of bridging vessel ranged from 15 to 21 cm. Results: The flow-through descending branch of lateral circumflex femoral artery flaps of five patients survived well. Wounds of 4 patients healed and wounds of 1 patient with infection under the flap on 3 days after operation healed after changing wound dressing and undergoing debridement for 2 weeks. After the operation, wrists and hands of 5 patients had adequate blood supply and ulnar and radial artery recovered patency. Follow-up of patients for 6 months to 1 year showed good flap appearance and adequate blood supply of burn hands. Conclusions: The flow-through descending branch of lateral

The use of negative pressure wound therapy (NPWT) has been widely documented as a technique to help heal complex wounds. This article presents the findings of a preliminary study which aimed to explore quality of life (QoL) experienced by patients undergoing NPWT as part of their wound care treatment in comparison to that of patients with a wound using traditional (standard) wound care therapies. A quasi-experimental study was undertaken, with patients treated in wound care/vascular clinics with chronic/acute wounds. QoL impact was measured using the Cardiff Wound Impact Schedule and administered post-consent at timed intervals. Our results identified that there were no real differences in QoL scores recorded by patients over the 12-week period. Although there was no overall interaction between the therapies used for wound healing, NPWT did have an effect on social life: during the first 2 weeks of the application of therapy, patients in the NPWT group reported an increase in the social life domain. The authors conclude that true QoL can only be elicited if an accurate baseline is established or if data is collected over a long enough period to allow comparison of scores over time. © 2012 The Authors.

Chronic wounds represent an aberrant biochemistry that creates a toxic proteolytic milieu which can be detrimental to the healing process. Rebalancing the wound microenvironment and addressing elevated protease activity (EPA) could therefore help facilitate healing. To understand how clinicians currently diagnose and manage excessive proteolytic activity, 183 survey responses from US wound specialists were collated and analysed to find out their perceptions on the role of proteases. The majority of respondents (>98%) believed proteases were important in wound healing and that a point-of-care (POC) protease test could be useful. This study yielded a low response rate (7.1%, n = 183); however, there were adequate data to draw significant conclusions. Specialists perceived that fibrin, slough, granulation tissue and rolled wound edges could indicate EPA. About 43% of respondents, however, failed to give a correct response when asked to review photographs to determine if excessive protease activity was present, and the perceived visual signs for EPA did not correlate with the wounds that had EPA; no statistical differences between professions were observed. Respondents chose debridement, wound cleansing and advanced therapies as important in reducing excessive protease activity. It was concluded that specialists have a need for POC diagnostic tests. On the basis of the responses to wound photos, it was determined that there were no visual cues clinicians could use in determining excessive protease activity. Additional research is recommended to evaluate the efficacy of a POC diagnostic test for protease activity and the treatments and therapies applied when EPA is found. © 2012 The Authors.

With the growing global problem of antibiotic resistance it is crucial that clinicians use antibiotics wisely, which largely means following the principles of antimicrobial stewardship (AMS). Treatment of various types of wounds is one of the more common reasons for prescribing antibiotics. This guidance document is aimed at providing clinicians an understanding of: the basic principles of why AMS is important in caring for patients with infected wounds; who should be involved in AMS; and how to conduct AMS for patients with infected wounds. We assembled a group of experts in infectious diseases/clinical microbiology (from the British Society for Antimicrobial Chemotherapy) and wound management (from the European Wound Management Association) who, after thoroughly reviewing the available literature and holding teleconferences, jointly produced this guidance document. All open wounds will be colonized with bacteria, but antibiotic therapy is only required for those that are clinically infected. Therapy is usually empirical to start, but definitive therapy should be based on results of appropriately collected specimens for culture. When prescribed, it should be as narrowly focused, and administered for the shortest duration, as possible. AMS teams should be interdisciplinary, especially including specialists in infection and pharmacy, with input from administrative personnel, the treating clinicians and their patients. Available evidence is limited, but suggests that applying principles of AMS to the care of patients with wounds should help to reduce the unnecessary use of systemic or topical antibiotic therapy and ensure the safest and most clinically effective therapy for infected wounds. © The Author 2016.

Full Text Available Joshua R Burke, Rachael Morley, Mustafa Khanbhai Academic Surgery Unit, Education and Research Centre, University Hospital of South Manchester, Manchester, UK Abstract: Negative pressure wound therapy (NPWT is the continuous or intermittent application of subatmospheric pressure to the surface of a wound that improves the wound environment, accelerates healing, and reduces wound closure time. Since its first documented use, this technology has lent itself to a number of adaptations, most notably, the development of portable devices facilitating treatment in the home care setting. With advancing surgical standards, wound healing is an important rate-limiting factor in early patient discharge and often a major cost of inpatient treatment. The efficacy of NPWT in the home care setting has been investigated through rate of wound closure, time in care, and patient experience. Rate of wound closure is the most appropriate primary end point. Much can be gleaned from patient experience, but the future success of portable NPWT will be measured on time in care and therefore cost effectiveness. However, there is a lack of level 1a evidence demonstrating increased efficacy of portable over inpatient NPWT. The development of portable NPWT is an encouraging innovation in wound care technology, and extending the benefits to the home care setting is both possible and potentially more beneficial.

Residential aged care homes have, or are in the process of implementing, electronic health record (EHR) systems to improve quality of care and reduce cost. For the system to deliver benefits, it must support nursing tasks and be seamlessly integrated into the nursing workflow. To identify whether and how an EHR system can do this most effectively, direct observation was conducted in a residential aged care home on nurses' use of EHR for wound care. The work processes of wound care and its documentation were investigated. Problems in the use of EHR were identified: 1) functional deficiencies of the EHR system which included a lack of functions to remind nurses of the existence of a wound chart, unavailability of an existent function when needed and a lack of sufficient detail in the information provided; 2) a lack of mobile devices to allow nurses to access the EHR system at the point-of-care, resulting in nurses using paper for point-of-care documentation. The findings suggest that continuous improvement in both the EHR system and its management is required to achieve integration of people, task, process and technology for the optimal benefits of EHR.

Although there is significant evidence supporting the use of negative pressure wound therapy (NPWT) for the treatment of lower extremity diabetic ulcers, currently available electrically powered NPWT systems are not ideally suited for treating smaller diabetic foot ulcers. The Smart Negative Pressure (SNaP™) Wound Care System is a novel, ultraportable device that delivers NPWT without the use of an electrically powered pump. It was specifically designed to meet the wound care needs of patients with diabetes. The SNaP System is compact, silent, mobile, easy-to-use, and available off-the-shelf. It is fully disposable and may offer other important benefits over electrically powered systems to both the clinician and patient. We review the evidence for use of NPWT for the treatment of diabetic wounds and discuss the potential benefits of this new NPWT technology for patients with diabetes. We also present a case series of four difficult lower extremity diabetic ulcers that were successfully treated with the SNaP System. This study suggests that the SNaP System may be a useful addition to the armamentarium of the diabetic wound care clinician. PMID:20663444

In this study, chlorhexidine hexametaphosphate (CHX-HMP) is investigated as a persistent antimicrobial coating for wound care materials. CHX-HMP was used as a wound care material coating and compared with chlorhexidine digluconate materials with respect to antimicrobial efficacy, toxicity and wound closure. Antimicrobial efficacy at day 1, 3 and 7 was observed with experimental and commercial materials. CHX-HMP coated materials had less toxic effect on human placental cells than commercial chlorhexidine dressings. CHX-HMP in pluronic gel did not delay healing but reduced wound colonization by E. faecalis. CHX-HMP could become a useful component of wound care materials with sustained antimicrobial efficacy, lower toxicity than chlorhexidine digluconate materials, and reduction in wound colonization without affecting closure.

Full Text Available Multidrug resistant Acinetobacter baumannii and its closely related species A. pittii and A. nosocomialis, all members of the Acinetobacter calcoaceticus-baumannii (Acb complex, are a major cause of hospital acquired infection. In the burn wound center of the Queen Astrid military hospital in Brussels, 48 patients were colonized or infected with Acb complex over a 52-month period. We report the molecular epidemiology of these organisms, their clinical impact and infection control measures taken. A representative set of 157 Acb complex isolates was analyzed using repetitive sequence-based PCR (rep-PCR (DiversiLab and a multiplex PCR targeting OXA-51-like and OXA-23-like genes. We identified 31 rep-PCR genotypes (strains. Representatives of each rep-type were identified to species by rpoB sequence analysis: 13 types to A. baumannii, 10 to A. pittii, and 3 to A. nosocomialis. It was assumed that isolates that belonged to the same rep-type also belonged to the same species. Thus, 83.4% of all isolates were identified to A. baumannii, 9.6% to A. pittii and 4.5% to A. nosocomialis. We observed 12 extensively drug resistant Acb strains (10 A. baumannii and 2 A. nosocomialis, all carbapenem-non-susceptible/colistin-susceptible and imported into the burn wound center through patients injured in North Africa. The two most prevalent rep-types 12 and 13 harbored an OXA-23-like gene. Multilocus sequence typing allocated them to clonal complex 1 corresponding to EU (international clone I. Both strains caused consecutive outbreaks, interspersed with periods of apparent eradication. Patients infected with carbapenem resistant A. baumannii were successfully treated with colistin/rifampicin. Extensive infection control measures were required to eradicate the organisms. Acinetobacter infection and colonization was not associated with increased attributable mortality.

Full Text Available Wound care is a major healthcare expenditure. Treatment of burns, surgical and trauma wounds, diabetic lower limb ulcers and skin wounds is a major medical challenge with current therapies largely focused on supportive care measures. Successful wound repair requires a series of tightly coordinated steps including coagulation, inflammation, angiogenesis, new tissue formation and extracellular matrix remodelling. Zinc is an essential trace element (micronutrient which plays important roles in human physiology. Zinc is a cofactor for many metalloenzymes required for cell membrane repair, cell proliferation, growth and immune system function. The pathological effects of zinc deficiency include the occurrence of skin lesions, growth retardation, impaired immune function and compromised would healing. Here, we discuss investigations on the cellular and molecular mechanisms of zinc in modulating the wound healing process. Knowledge gained from this body of research will help to translate these findings into future clinical management of wound healing.

Being a complex traumatic event, burn injury also affects other organ systems apart from the skin. Wounds undergo various pathological changes which are accompanied by alterations in the molecular environment. Information about molecules may be obtained with the use of Raman spectroscopy and Fourier-transform infrared spectroscopy, and when combined, both methods are a powerful tool for providing material characterization. Alterations in the molecular environment may lead to identifying objective markers of acute wound healing. In general, incubation of samples in solutions of L-ascorbic acid and 5% and 7% orthosilicic acid organizes the collagen structure, whereas the increased intensity of the Raman bands in the region of 1500-800 cm- 1 reveals regeneration of the burn tissue. Since oxidative damage is one of the mechanisms responsible for local and distant pathophysiological events after burn, antioxidant therapy can prove to be beneficial in minimizing burn wounds, which was examined on the basis of human skin samples and chicken skin samples, the latter being subject to modification when heated to a temperature sufficient for the simulation of a burn incident.

The aim of the present study was morphological and morphometric investigation of burn healing impacts of an honey, milk, and Aloe vera (HMA) ointment on experimentally induced second-degree burns, to approve the medicinal basis of its use in Iranian traditional medicine. A total of 21 male Albino rats weighing 200 to 300 g were divided into 3 groups of 7, including (1) control group, (2) positive control group, and (3) the treatment group that were treated with eucerin, silver sulfadiazine 3% and HMA ointment 5% respectively.After anesthetizing, the second-degree burns (1 cm(2) areas) were made on the back of the animals using a digital controlled hot plaque, and each group was treated topically, based on the time scheduled. Then, skin punch biopsies were obtained on the 1st, 14th, and 28th days of post-burn induction; processed; and stained using hematoxylin and eosin and Masson's trichrome methods. The results showed that HMA ointment induces cell proliferation, increasing the wound closure rate, blood vessel counts, and collagen fiber density in treated animals. It also reduced the wound secretions, inflammation, and scar formation. According to the obtained morphological, morphometric results, we concluded that the traditional HMA ointment, which is rich in therapeutic biomaterials and minerals, has multiple healing effects on burn wounds in rats. © The Author(s) 2016.

An observation study, employing a nominal questionnaire, was conducted to explore the relationship between disgust emotions, response to surgical wounds and engagement in wound management. A total of 101 patients were recruited at the Royal Free Hospital plastic surgery dressing clinic, following a variety of elective or emergency surgical procedures. Participants were asked to complete the Haidt Disgust Sensitivity Questionnaire and a Wound Management Questionnaire. Participants were observed during the consultation to assess characteristics of the wound and indicators of disgust. Data were analysed using analysis of variance (ANOVA) and Z-test, with the primary outcome measure being engagement in care, as rated by the dressing nurses. Mean disgust sensitivity was significantly higher in females and in those who were observed to avert their gaze or appeared tearful during the consultation. Sensitivity was lower in participants who felt able to help the nurse with their dressing, those able to clean their wound, and those able to do their own dressing at home and who were not worried about the appearance of their scar. Wound size and severity were also found to have a significant impact on engagement in care. Both biomedical factors, such as size and severity of a wound, and psychological factors, such as disgust sensitivity, are important in wound care. Screening for disgust sensitivity pre-operatively, in association with the modified Wound Management Questionnaire, has the potential to identify patients who are at risk of avoidant behaviour and to develop psychological interventions to promote wound self management.

Burns are very common in sub-Saharan Africa and are considered to be a major health care problem. The management of burns in many African countries is challenged by limited financial resources, inaccessible health care facilities, lack of trained professionals and superstition. These limitations are related to the many burned patients seeking treatment from traditional healers. The use of traditional remedies, plant and animal products are seen as an important aspect of burn management as it is both an affordable and respected treatment modality. Despite its popularity, the use of traditional burn care remedies is faced with many challenges as little research has been done on its effectiveness, dosage and adverse reactions. This paper reviewed the traditions and customs associated with traditional burn care as well as the use of plant, animal and mineral products used by traditional healers.

Bloodstream infections are potentially life-threatening diseases. They can cause serious secondary infections, and may result in endocarditis, severe sepsis or toxic-shock syndrome. Pseudomonas aeruginosa is an opportunistic pathogen and one of the most important etiological factors responsible for nosocomial infections, mainly in immuno-compromissed hosts, characteristic of patients with severe burns. Its multiresistance to antibiotics produces many therapeutic problems, and for this reason, the development of an alternative method to antibiotic therapy is needed. Photodynamic inactivation (PDI) may be an effective and alternative therapeutic option to prevent bloodstream infections in patients with severe burns. In this study we report the use of PDI to prevent bloodstream infections in mice with third-degree burns. Burns were produced on the back of the animals and they were infected with 109 cfu/mL of multi-resistant (MR) P. aeruginosa. Fifteen animals were divided into 3 groups: control, PDT blue and PDT red. PDT was performed thirty minutes after bacterial inoculation using 10μM HB:La+3 and a light-emitting diode (LED) emitting at λ=460nm+/-20nm and a LED emitting at λ=645 nm+/-10nm for 120s. Blood of mice were colected at 7h, 10h, 15h, 18h and 22h pos-infection (p.i.) for bacterial counting. Control group presented 1×104 cfu/mL in bloodstream at 7h p.i. increasing to 1×106 at 22h, while mice PDT-treated did not present any bacteria at 7h; only at 22h p.i. they presented 1×104cfu/mL. These results suggest that HB:La+3 associated to blue LED or red LED is effective to delay and diminish MR P.aeruginosa bloodstream invasion in third-degree-burned mice.

Several randomized controlled trials comparing negative-pressure therapy to standard wound care for chronic wounds have been published. Although these studies suggest a benefit for negative-pressure therapy, the majority of the review articles on the topic conclude that the studies are inconclusive. The authors conducted a quantitative meta-analysis of the effectiveness of negative-pressure therapy for the management of chronic wounds. The MEDLINE, EMBASE, and Cochrane databases were searched from 1993 to March of 2010 for randomized controlled trials comparing negative-pressure therapy to standard wound care for chronic wounds. Measures of wound size and time to healing, along with the corresponding p values, were extracted from the randomized controlled trials. Relative change ratios of wound size and ratios of median time to healing were combined using a random effects model for meta-analysis. Ten trials of negative-pressure therapy versus standard wound care were found. In the negative-pressure therapy group, wound size had decreased significantly more than in the standard wound care group (relative change ratio, 0.77; 95 percent confidence interval, 0.63 to 0.96). Time to healing was significantly shorter in the negative-pressure therapy group in comparison with the standard wound care group (ratio of median time to healing, 0.74; 95 percent confidence interval, 0.70 to 0.78). This quantitative meta-analysis of randomized trials suggests that negative-pressure therapy appears to be an effective treatment for chronic wounds. An effect of publication bias cannot be ruled out. Therapeutic, II.

Management of full-thickness facial burns remains one of the greatest challenges. Controversy exists among surgeons regarding the use of early excision for facial burns. Unfortunately, delayed excision of deeper burns often results in more scarring and subsequent reconstruction becomes more difficult. A collagen-elastin matrix is used to improve the quality of the reconstructed skin, to reduce scarring and to prevent wound contraction. It serves as a foundation for split thickness skin graft and enhances short and long-term results. We report the usage of a collagen-elastin matrix during single-step wound closure technique of severe full-thickness facial burns in 15 children with large burned body surface area, and also we review the literature about pediatric facial burns. There were 15 pediatric patients with severe facial burns, 8 girls and 7 boys ranging in age from 10 months to 12 years, mean age 7 years and 6 months old. The facial burn surface area (FBSA) among the patients includes seven patients with 100%, five with 75%, and three with 50%. The average total body surface area (TBSA) for the patients was 72%, ranging between 50 and 90%. 5 of the patients' admissions were late, more than four days after burns while the rest of the patients were admitted within the first four days (acute admission time). The burns were caused by flame in eight of the patients, bomb blast in four, and scalding in three. All patients were treated by the simultaneous application of the collagen-elastin matrix and an unmeshed split thickness skin graft at Turgut Özal Medical Center, Pediatric Burn Center, Malatya, Turkey. After the treatment only two patients needed a second operation for revision of the grafts. All grafts transplanted to the face survived. The average Vancouver scar scales (VSS) were 2.55±1.42, ranging between one and six, in the first 10 of 15 patients at the end of 6 months postoperatively. VSS measurements of the last 5 patients were not taken since the 6

Multidisciplinary team approach is an essential component of evidence-based wound management in the community. The objective of this study was to identify and describe community-based multidisciplinary wound care teams in Ontario. For the study, a working definition of a multidisciplinary wound care team was developed, and a two-phase field evaluation was conducted. In phase I, a systematic survey with three search strategies (environmental scan) was conducted to identify all multidisciplinary wound care teams in Ontario. In phase II, the team leads were surveyed about the service models of the teams. We identified 49 wound care teams in Ontario. The highest ratio of Ontario seniors to wound team within each Ontario health planning region was 82,358:1; the lowest ratio was 14,151:1. Forty-four teams (90%) participated in the survey. The majority of teams existed for at least 5 years, were established as hospital outpatient clinics, and served patients with chronic wounds. Teams were heterogeneous in on-site capacity of specialized diagnostic testing and wound treatment, team size, and patient volume. Seventy-seven percent of teams had members from three or more disciplines. Several teams lacked essential disciplines. More research is needed to identify optimal service models leading to improved patient outcomes. © 2014 by the Wound Healing Society.

Wounds that exhibit delayed healing add extraordinary clinical, economic, and personal burdens to patients, as well as to increasing financial costs to health systems. New interventions designed to ease such burdens for patients with cancer, renal, or ophthalmologic conditions are often cleared for approval by the U.S. Food and Drug Administration (FDA) using multiple endpoints but the requirement of complete healing as a primary endpoint for wound products impedes FDA clearance of interventions that can provide other clinical or patient-centered benefits for persons with wounds. A multidisciplinary group of wound experts undertook an initiative, in collaboration with the FDA, to identify and content validate supporting FDA criteria for qualifying wound endpoints relevant to clinical practice (CP) and patient-centered outcomes (PCO) as primary outcomes in clinical trials. As part of the initiative, a research study was conducted involving 628 multidisciplinary expert wound clinicians and researchers from 4 different groups: the interdisciplinary core advisory team; attendees of the Spring 2015 Symposium on Advanced Wound Care (SAWC); clinicians employed by a national network of specialty clinics focused on comprehensive wound care; and Association for the Advancement of Wound Care (AAWC) and Wound Healing Society (WHS) members who had not previously completed the survey. The online survey assessed 28 literature-based wound care endpoints for their relevance and importance to clinical practice and clinical research. Fifteen of the endpoints were evaluated for their relevance to improving quality of life. Twenty-two endpoints had content validity indexes (CVI) ≥ 0.75, and 15 were selected as meriting potential inclusion as additional endpoints for FDA approval of future wound care interventions. This study represents an important first step in identifying and validating new measurable wound care endpoints for clinical research and practice and for regulatory

To examine the efficacy of Exsikines (patent-pending) in the treatment of chronic wounds. Subjects were treated with Exsikines every 3 to 5 days, wound healing parameters were monitored and compared with other published studies. A clinical practice. A total of 21 patients (22 chronic wounds each identified etiologically) were randomly selected for this study, based on presentation of Stage II or III wounds using the Wagner wound classification system of at least 6 weeks' duration. The average wound age in this study was 12.48 months with a median wound age of 3 months. To reflect clinical practice scenarios, no other criteria for inclusion were required. The study was initiated with 24 patients with 24 chronic wounds. Three patients were removed from the study for nonadherence of the therapeutic protocol of Exsikines application. Baseline measurements were taken of all wounds, and time of persistence was noted. Exsikines, a patent-pending mixture of homologous-derived blood products containing human cytokines and other growth factors, was applied to the wounds at approximately 4-day intervals. Wound measurements were taken intermittently. Healing times, healing rates, recurrence rates, cost of treatments, and other parameters were determined. One hundred percent of the wounds were completely healed within an average of 53.5 days (median, 41.5 days). Recurrence monitoring after wound closure averaged 8.9 months. Recurrence in diabetic ulcers and pressure ulcers occurred at a rate of 7.14% and 16.67%, respectively. Wounds were documented by digital photography. In comparison to standard wound care, as well as other wound care products, Exsikines offers a very efficacious method of treating chronic wounds.

Diabetic foot ulcers are a feared complication of diabetes. Care delivered via telemedicine is suggested to be a more integrated care pathway to manage diabetic foot ulcers than traditionally delivered healthcare. Our aim was to explore patients' experiences with telemedicine follow-up care as compared to traditional care. Interpretive description was used as an analysis strategy. Data were collected using individual semi-structured interviews in the context of a larger ongoing clustered randomized controlled trial. Twenty-four patients (13 in the intervention group; 11 in the control group), aged 38-88 years were purposively recruited from the RCT in order to obtain a diverse sample in terms of group composition (intervention vs. control), age, gender, marital status, setting, and comorbidities present. The control group received traditional care. Three themes emerged from the interpretive analysis: competence of healthcare professionals, continuity of care, and easy access. This was independed of types of follow-up that had limited impact on the patients' follow-up experiences. Competence of healthcare professionals and continuity of care were crucial, because they can either enhance or jeopardize wound care. If these two latter factors were absent, patients would lose confidence in the wound care process. If this happened, patients pointed out that the expert knowledge of a specialist clinic was essential to receive good care. When telemedicine functioned optimally, telemedicine was an advantage in the treatment, because the images quickly captured changes in the wound healing that immediately could be corrected. Easy access is important for patients, but the importance of accessibility appears to be primary when the other two factors were present. The best wound care pathway for patients with diabetes foot ulcers is depended on a combination of competence and professional skills in wound management, and continuity of care. If telemedicine is functioning as

Full Text Available Background. The evidence exists that radicals are crucial agents necessary for the wound regeneration helping to enhance the repair process. Materials and methods. The lineshape of the electron paramagnetic resonance (EPR spectra of the burn wounds measured with the low microwave power (2.2 mW was numerically analyzed. The experimental spectra were fitted by the sum of two and three lines. Results. The number of the lines in the EPR spectrum corresponded to the number of different groups of radicals in the natural samples after thermal treatment. The component lines were described by Gaussian and Lorentzian functions. The spectra of the burn wounds were superposition of three lines different in shape and in linewidths. The best fitting was obtained for the sum of broad Gaussian, broad Lorentzian, and narrow Lorentzian lines. Dipolar interactions between the unpaired electrons widened the broad Gaussian and broad Lorentzian lines. Radicals with the narrow Lorentzian lines existed mainly in the tested samples. Conclusions. The spectral shape analysis may be proposed as a useful method for determining the number of different groups of radicals in the burn wounds.
Full Text Available Electrical burns are infrequent relative to other injuries, but they are associated with high morbidity and mortality. The aim of this study was to assess management and follow-up results of pediatric patients’ who observed in intensive care unit and also review the precautions for preventing electrical burns.Materials and methods: Totally 22 patients aged under 17 years who were observed in the burn intensive care unit of Şanlıurfa Education and Research Hospital during the period between July 2009-October 2010. Cases were investigated retrospectively. The patients’ age, gender, total burn surface area, length of stay in hospital, musculo-skeletal system complication, cardiovascular system complication, kidney damage and attempts were recorded.Results: Of the 22 cases, 19 (86.3% were male and 3 (13.7% were female. The mean age of the patients was 11.5 years. In 10 (45.4% children burns were occurred in workplace and working area and 12 (54.6% were occurred in the home environment. Depth of burns were third degree in 10 (45.4% children and second degree in 12 (54.6%. The mean percentage of burn surface area was 25.9%. The mean length of stay in hospital was 17 days. Debridement and grafting were performed to 12 (54.6% cases and 10 (45.4% children were treated with dressings. No patient had increased creatinine kinase levels, oliguria, myoglobuinuria and arrhythmia. The mean hospitalization time was 17 days.Conclusion: Nearly half of patients underwent debridement plus grafting. None of our patients developed renal failure other severe system dysfunction.
According to definition, chronic wounds do not show any tendency for healing over months. From the socio-economic perspective they are of great importance due to their frequency, patient burden and costs for the health system. In wound care, medical devices play a crucial, even more important role than drugs as nearly every wound needs at least a dressing. A wound passes through several phases of wound healing, which often demand different therapies and differentiated wound dressings in the sense of a "phase-adapted" wound therapy. "Modern wound care" reflects a cross-sectoral, interdisciplinary and interprofessional approach founded on evidence-based and quality-assured procedures according to the most recent medical knowledge. Clinical research on chronic wounds is characterised by a great variety of wound types and conditions, the strong impact of pathogenetic factors and complications, a multifaceted, frequently still manual therapy and long periods of healing. In many instances, several treatments are applied intermediately in the same patient, which serve different purposes and thus require different study endpoints. An analysis of the European Wound Management Association (EWMA) revealed that, on an international level, only few of the published clinical trials on chronic wounds meet the basic quality requirements. Accordingly, it is the objective to establish national and international consensus on standards of the methodology and interpretation of wound outcomes, such as the most recent EWMA activities and the German national consensus conference started in 2012. EXAMPLE OF A HIGH-QUALITY CLINICAL WOUND STUDY: As an example of a high quality randomised study on chronic wounds, hyperbaric oxygen treatment (HBOT) was evaluated as adjuvant treatment for diabetic foot ulcers compared to placebo (Löndahl et al., 2010). This trial is characterised by a diligent study design, a substantiated study rationale and an independent steering committee. Precise and

The aim of this study was to determine the basic epidemiological characteristics of severely burned children who were admitted to the intensive care unit (ICU), Department of Burns and Reconstructive Surgery Faculty Hospital Brno, Czech Republic in the years 1997-2009. We collected and evaluated epidemiological data such as age, sex, burn etiology, length of hospitalization, duration of the ICU stay, surgical or conservative therapeutic strategies, the use of mechanical ventilation and its duration, day and month of injury and the extent of burned area. In total 383 children (253 boys, 130 girls) aged 0-14 years, underwent intensive care for at least 48h. Male to female ratio was 1.95:1. The average range of burn area in the group was 16.43±12.86% TBSA (total body surface area). During the reporting period, 16 children were admitted with burns over 50% TBSA. 328 children suffered burns indoors, with 55 children being burned outdoors. Indoor/outdoor ratio was set at 5.96:1. The most frequent etiological agent was scalding (hot water, soup, coffee, oil, tea). The total number of scalded children in this group was 312 (81.46%). Mechanical ventilation was used in 96 cases (25.07% of all the admitted patients). The duration of mechanical ventilation in these patients was 8.03±5.67 days in average. The average length of stay in ICU was 10.71±10.92 days and total length of hospital stay was an average of 21.55±14.55 days. A total of 184 patients (48.04%) were treated surgically and therefore required necrectomy and skin grafting. The other 199 (51.96%) patients were treated conservatively. During the reporting period 3 children died (0.78%). In our report we identify basic epidemiological data defined in the aim of this study for burned children requiring intensive care.

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

In recent years, a new technology for autologous epidermal harvesting has been developed to produce epidermal skin grafts (ESGs) for use over wounds. This technology employs negative pressure and heat to raise the epidermal skin layer, allowing for consistent and reproducible epidermal harvesting. The aim of this case series is to present the authors' experience using an automated, epidermal harvesting system to produce ESGs to treat wounds of patients with multiple comorbidities. This case series was conducted between January 1, 2013 and December 31, 2014. Patients with wounds (≤ 25 cm2) that failed to heal were treated with ESGs by a group of 3 wound care physicians in 2 outpatient wound care centers in a community health center setting. A total of 94 patients with 102 wounds were identified. Of the 94 patients, 3 were noncompliant and 9 were lost to follow-up. Therefore, 82 patients with 90 wounds were included in the analysis. The majority of wounds demonstrated epithelialization (83/90, 92.2%). Of the 90 wounds, 75 (83.3%) healed following epidermal grafting, 4 (4.4%) wounds displayed improvement, and 11 (12.2%) did not heal. Minimal or no pain at the donor site was reported by the patients, and all donor sites healed without complications. This case series provides additional evidence for the use of ESGs for the treatment of wounds that fail to heal.

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

Too many wound care research studies are poorly designed, badly executed, and missing crucial data. The objective of this study is to create a series of principles for all stakeholders involved in clinical or comparative effectiveness research in wound healing. The Delphi approach was used to reach consensus, using a web-based survey for survey participants and face-to-face conferences for expert panel members. Expert panel (11 members) and 115 wound care researchers (respondents) drawn from 15 different organizations. Principles were rated for validity using 5-point Likert scales and comments. A 66% response rate was achieved in the first Delphi round from the 173 invited survey participants. The response rate for the second Delphi round was 46%. The most common wound care researcher profile was age 46-55 years, a wound care clinic setting, and >10 years' wound care research and clinical experience. Of the initial 17 principles created by the panel, only four principles were not endorsed in Delphi round 1 with another four not requiring revision. Of the 14 principles assessed by respondents in the second Delphi round, only one principle was not endorsed and it was revised; four other principles also needed revision based on the use of specific words or contextual use. Of the 19 final principles, three included detailed numbered lists. With the wide variation in design, conduct, and reporting of wound care research studies, it is hoped that these principles will improve the standard and practice of care in this field. © 2012 by the Wound Healing Society.

A novel burn wound hydrogel dressing has been previously developed which is composed of 2-acrylamido-2-methylpropane sulfonic acid sodium salt with silver nanoparticles. This study compared the antimicrobial efficacy of this novel dressing to two commercially available silver dressings; Acticoat™ and PolyMem Silver(®). Three different antimicrobial tests were used: disc diffusion, broth culture, and the Live/Dead(®) Baclight™ bacterial viability assay. Burn wound pathogens (P. aeruginosa, MSSA, A. baumannii and C. albicans) and antibiotic resistant strains (MRSA and VRE) were tested. All three antimicrobial tests indicated that Acticoat™ was the most effective antimicrobial agent, with inhibition zone lengths of 13.9-18.4mm. It reduced the microbial inocula below the limit of detection (10(2)CFU/ml) and reduced viability by 99% within 4h. PolyMem Silver(®) had no zone of inhibition for most tested micro-organisms, and it also showed poor antimicrobial activity in the broth culture and Live/Dead(®) Baclight™ assays. Alarmingly, it appeared to promote the growth of VRE. The silver hydrogel reduced most of the tested microbial inocula below the detection limit and decreased bacterial viability by 94-99% after 24h exposure. These results support the possibility of using this novel silver hydrogel as a burn wound dressing in the future. Copyright © 2013 Elsevier Ltd and ISBI. All rights reserved.

The aims of this study are: firstly, to investigate if admission to specialized burn critical care units leads to better clinical outcomes; secondly, to elucidate if the multidisciplinary critical care contributes to this superior outcome. A multi-centre cohort analysis of a prospectively collected national database of 1759 adult burn patients admitted to 13 critical care units in England and Wales between 2005 and 2011. Units were contacted via telephone to establish frequency and constitution of daily ward rounds. Critical care units were categorized into 3 settings: specialized burns critical care units, generalized critical care units and 'visiting' critical care units. Multivariate logistic regression analysis and propensity dose-response analysis were used to calculate risk adjusted mortality. Multivariate logistic regression analysis shows that admission to a specialized burn critical care service is independently associated with significant survival benefit compared to generalized critical care unit (adjusted OR for in-hospital death 1.81, [95% CI, 1.24, 2.66]) and 'visiting' critical care services (adjusted OR for in-hospital death 2.24 [95% CI, 1.49, 3.38]). Further analysis using propensity dose-response analysis demonstrates that risk-adjusted in-hospital mortality rate decreased as the dose of multidisciplinary care increased, with an adjusted odds ratio of 1 (specialized burn critical care units), 1.81 (generalized critical care units) and 2.24 ('visiting' critical care units). Admission to a specialized burn critical care service is independently associated with significant survival benefit. This is, at least in part, due to care being provided by a fully integrated multidisciplinary team. Copyright © 2017 Elsevier Ltd and ISBI. All rights reserved.

Because of their extensive wounds, burn patients are chronically exposed to inflammatory mediators. Thus, burn patients, by definition, already have "systemic inflammatory response syndrome." Current definitions for sepsis and infection have many criteria (fever, tachycardia, tachypnea, leukocytosis) that are routinely found in patients with extensive burns, making these current definitions less applicable to the burn population. Experts in burn care and research, all members of the American Burn Association, were asked to review the literature and prepare a potential definition on one topic related to sepsis or infection in burn patients. On January 20, 2007, the participants met in Tucson, Arizona to develop consensus for these definitions. After review of the definitions, a summary of the proceedings was prepared. The goal of the consensus conference was to develop and publish standardized definitions for sepsis and infection-related diagnoses in the burn population. Standardized definitions will improve the capability of performing more meaningful multicenter trials among burn centers.
Open-to-Air Is a Viable Option for Initial Wound Care in Necrotizing Soft Tissue Infection that Allows Early Detection of Recurrence without Need for Painful Dressing Changes or Return to Operating Room.
Yang, Derek; Davies, April; Burge, Bailey; Watkins, Phillip; Dissanaike, Sharmila
The standard treatment of necrotizing soft tissue infection (NSTI) includes extensive surgical debridement. Care of these debridements is challenging because of the size of the wound and associated pain. A potential solution is to leave the wounds open-to-air in the period after the initial debridement, allowing for regular inspection at bedside while reducing pain associated with frequent dressing changes. We evaluated the feasibility of this approach from a pain control standpoint. An audit of wound care modalities used on adult patients with NSTI admitted to a regional burn center between January 2009 and May 2014 was performed. Patients with at least one operation were included. Those opting for palliative care were excluded. Wound care was divided into four categories: open-to-air (OTA), negative-pressure wound therapy (NPWT), packing, and ointment. Wound care, pain score, pain medication use, and number of operations were collected for the first seven days after initial debridement. Pain management was assessed by pain scores. Analgesic use was measured and compared using conversion to morphine milligram equivalents (MME). Ninety-six patients were included; 67% were men with average age of 50 years, resulting in a total of 672 days of wound care evaluated: 69 days of OTA, 127 days of NPWT, 200 days of packing, and 126 days of ointment (150 days were undocumented). Average daily pain score from all wound care modalities was 2.00. Negative pressure wound therapy had the highest reported daily pain score (2.18, p = 0.034), whereas OTA had the lowest pain score (1.63, p post-debridement period of NSTI to reduce pain, while permitting frequent re-evaluation for quick recognition of disease progression and repeat operative debridement if necessary.

Burn wounds are a global public health problem, which affects all countries, no matter the development stage and occurs in all age groups, from toddlers to elderly. In spite of burns being the cause of numerous household and work accidents, there are still no clear stated unanimous rules for their treatment. Every day new products appear on the market, each of them trying to prove more effective. Since ancient times, silver has been known for its antimicrobial properties, so it has been used for a long time in the treatment of burns and other types of wounds. One of the relatively modern methods of treatment is applying silver sheets on the scald lesions. In this paper, which was part of a larger study (research for a PhD thesis), concerning prevention and treatment of the post-burn pathological scars, the cases of some patients with burns, who were treated by using the above mentioned method were presented and analyzed. The results obtained by applying silver sheets were then commented and interpreted, pointing out the advantages and disadvantages compared to silver sulfadiazine creams and ointments, which have already been used at a large scale. The prevention and treatment of post-burn pathological (hypertrophic and keloid) scars is a field in which still little is known and in which there are also no clearly set therapy plans. We hope that through this research and the following ones we will manage to establish some major guidelines concerning the prevention of pathological scars, which are not only disabling, but also a major aesthetic issue for any patient, in order to obtain better outcomes.

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

Low-and middle-income (LMIC) countries account for 90% of all reported burns, nevertheless there is a paucity of providers to treat burns. Current studies on burns in LMICs have not evaluated the gap between care seeking and receiving. This study explores this gap across socioeconomically similar populations in a multi-country population based assessment to inform burn care strategies. The Surgeons OverSeas Assessment of Surgical Need (SOSAS) instrument is a cross sectional national, cluster random sampling survey administered in Nepal, Rwanda, Sierra Leone, and Uganda from 2011 to 2014. The survey identifies burn etiology, demographics, timing, disability, and barriers to receiving care. Among 13,763 individuals surveyed, 896 burns were identified. Rwanda had the highest proportion of individuals seeking and receiving care (91.6% vs 88.5%) while Sierra Leone reported the fewest (79.3% vs 70.3%). Rwanda reported the largest disability while Nepal reported the highest proportion with no disability (47.5% vs 76.2%). Lack of money, healthcare providers, and rural living reduce the odds of receiving care by 68% and 85% respectively. Despite similar country socioeconomic characteristics there was significant variability in burn demographics, timing, and disability. Nevertheless, being geographically and economically disadvantaged predict lack of access to burn care. Copyright © 2018 Elsevier Ltd and ISBI. All rights reserved.

Chronic wounds are a major health burden and have a severe impact on well-being. This synthesis of qualitative studies was undertaken to inform a health technology assessment of antimicrobial wound dressings. It aimed to explore patients' experiences of chronic wounds and determine improvements for clinical practice. Inclusion criteria included use of qualitative methods, and English language publication. Databases searched included MEDLINE (Ovid), MEDLINE in Process (Ovid), EMBASE (Ovid), CINAHL (EBSCOHost), and PsychInfo (EBSCOHost). Searches were limited to 1990-2014. The method of analysis was Framework synthesis. A total of 20 studies were included. The synthesis confirmed the severe physical, social and psychological impact of the chronic wound. Inadequately controlled pain and sleeplessness, restrictions to lifestyle, and the loss of previous life roles can lead to feelings of hopelessness and helplessness and therefore depression and anxiety. Dressings and dressing changes are a key aspect of treatment and provide opportunities for positive interaction and person centred-care. People with chronic wounds can be supported to live well within the severe physical, psychological and social restrictions of a chronic wound. Effective clinical pain management and the recognition of the experience of acute and chronic pain are of the utmost importance to people with a chronic wound. Treatment should not be purely focused on healing but incorporate symptom management, coping and wellbeing via person-centred and holistic care. Copyright © 2017 Tissue Viability Society.

Stevens-Johnson syndrome/toxic epidermal necrolysis (SJS/TEN) is a systemic disease that can be associated with debilitating acute and chronic complications across multiple organ systems. As patients with acute SJS/TEN are often treated in a burn intensive care unit (BICU), we surveyed burn centers across the United States to determine their approach to the care of these patients. The goal of our study was to identify best practices and possible variations in the care of patients with acute SJS/TEN. We demonstrate that the method of diagnosis, use of systemic therapies, and involvement of subspecialists varied significantly between burn centers. Beyond supportive care provided to every patient, our data highlights a lack of standardization in the acute care of patients with SJS/TEN. A comprehensive guideline for the care of patients with acute SJS/TEN is indicated. Copyright © 2015 Elsevier Ltd and ISBI. All rights reserved.

In Pakistan the practice of managing extensive burns in dedicated intensive care units is not well established. This audit aims to define the characteristics of the victims of major burns and factors that increase mortality and outcome of the protocol-based management in a dedicated burns intensive care unit (BICU). This prospective audit included all patients admitted to the BICU of Suleiman Dawood Burns Unit in Karachi from 1st September 2002 to 31st August 2011. Demographic information, type and place of burn, total body surface area burn (TBSA), type of organ support provided, length of ICU stay, any associated medical diseases, and out outcome were documented. A total of 1597 patients were admitted to the BICU in 9 years. Median age of the patients was 22 (IQR =32-7). 32% victims were children 50 years old. Male to female ratio was 1.4:1. Fire was the leading cause of burns in adults (64%) and scald burns were most common in (64%) in children. 72.4% of the accidents happened at home, where kitchen was the commonest location (597 cases). Mean TBSA burnt was 32.5% (SD ± 22.95%, 95%CI: 31.36-33.61). 27% patients needed ventilatory support, 4% were dialyzed and split skin graftings were performed in 20% patients. Average length of ICU stay was 10.42 days. Epilepsy, psychiatric illness and drug addiction were not common associations with burns. Overall mortality was 41.30% but it decreased over the years from 75% to 27%. Groups of people most vulnerable to sustain burn are young females getting burnt in the kitchen, young males getting burnt at work, and small children falling in pots of hot water stored for drinking or bathing. TBSA >40%, age >50 years, fire burn and female gender were associated with a higher risk of death. Carefully planned, protocol based management of burn patients by burn teams of dedicated healthcare professionals, even with limited resources reduced mortality.

Full Text Available Objective: To evaluate drug utilization and associated costs for the treatment of patients admitted in burn care unit of a tertiary care hospital. Methods: A prospective cross sectional study was conducted for a period of 15 months at Basaweshwara Teaching and General Hospital (BTGH, Gulbarga and the data collected was analyzed for various drug use indicators. Results: A total of 100 prescriptions were collected with 44% belonging to males and 56% to females. The average number of drugs per prescription ranged from 4.5 to 9.5. 9.5% of generics and 92% of essential drugs were prescribed. The opioid analgesics and sedatives were prescribed to all the patients who were admitted in burn care unit. The (Defined daily dose DDD/1 000/day for amikacin (359 was the highest followed by diclofenac sodium (156, pantoprazole (144, diazepam (130, ceftazidime (124, tramadol (115, ceftriaxone (84 and for paracetamol (4 which was the lowest. Conclusions: Significant amount of the money was spent on procurement of drugs. Most of the money was spent on prescribed antibiotics. The prescription of generic drugs should be promoted, for cost effective treatment. Hence the results of the present study indicate that there is a considerable scope for improvement in the prescription pattern.

Skin burn is a health problem that requires fast and accurate treatment. If not well-treated, the burn will cause various damaging conditions for the patient. The leaf extract of Madeira vine ( Anredera cordifolia (Ten.) Steenis), or popularly known as Binahong in Indonesia, has been used to treat various diseases. The purpose of this research is to determine the effects of leaf extracts of Madeira vine ( A. cordifolia (Ten.) Steenis) on skin burn healing process in rats as an animal model. In this research, there were four treatment groups: G0, G1, G2, and G3, each consisting of five rats. All these rats were given skin burns, using hot metal plates. Then, sulfadiazine was given to G0, 2.5% leaf extract of Madeira vine was given to G1, 5% extract was given to G2, and 10% extract was given to G3, for straight 14 days topically, 3 times a day. At the end of the treatment period, skin excisions were conducted, and histopathological examination was carried out. Microscopic observation on the wound healing process on the collagen deposition, polymorphonuclear infiltration, angiogenesis, and fibrosis showed that G2 had a significant difference with G0, G1, and G3 (pMadeira vine, which have the antioxidant, anti-inflammatory, and antibacterial effects. The ointment from the 5% leaf extract of Madeira vine ( A. cordifolia (Ten.) Steenis) has been proven to be effective to be used for topical burn therapy.
Full Text Available Consensus regarding optimal burns intensive care (BICU patient management is lacking. This study aimed to assess whether ventilation strategies, cardiovascular support and sedation in BICU patients have changed over time, and whether this affects outcome. A retrospective observational study comparing two 12-patient BICU cohorts (2005/06 and 2010/11 was undertaken. Demographic and admission characteristics, ventilation parameters, sedation, fluid resuscitation, cardiovascular support and outcome (length of stay, mortality data were collected from patient notes. Data was analysed using T-tests, Fisher's exact and Mann-Whitney U tests. In our study cohort groups were equivalent in demographic and admission parameters. There were equal ventilator-free days in the two cohorts 10 ± 12.7 vs. 13.3 ± 12.2 ventilator free days; P = 0.447. The 2005/06 cohort were mechanically ventilated more often than in 2010/11 cohort (568 ventilator days/1000 patient BICU days vs. 206 ventilator days/1000 patient BICU days; P = 0.001. The 2005/06 cohort were ventilated less commonly in tracheostomy group/endotracheal tube spontaneous (17.8% vs. 26%; P = 0.001 and volume-controlled modes (34.4% vs. 40.8%; P = 0.001. Patients in 2010/11 cohort were more heavily sedated (P = 0.001 with more long-acting sedative drug use (P = 0.001 than the 2005/06 cohort, fluid administration was equivalent. Patient outcome did not vary. Inhalational injury patients were ventilated in volume-controlled (44.5% vs. 28.1%; P = 0.001 and pressure-controlled modes (18.2% vs. 9.5%; P = 0.001 more frequently than those without. Outcome did not vary. This study showed there has been shift away from mechanical ventilation, with increased use of tracheostomy/tracheal tube airway spontaneous ventilation. Inhalation injury patients require more ventilatory support though patient outcomes do not differ. Prospective trials are required to establish which strategies confer benefit.

The increasing consumption of antibiotics in hospitals and the economic implications of this increase lead to survey this consumption in the various hospital units. Our study proposes to measure the annual antibiotic use and antimicrobial resistance in an intensive care Burn department in order to manage the control measures. The study was conducted during a 5 year period (1 January 2000 to 31 December 2004). The average number of admissions was 204/year and the mean number of hospitalisation was 4036/year. Antimicrobial susceptibility testing was performed by disk diffusion method. Susceptibility testing data were stored in a laboratory data base using whonet 5.3 software. The consumption of following antibiotics: imipenem, ceftazidime, ofloxacin, ciprofloxacin, piperacillin-tazobactam was measured by antimicrobial density (AD) witch takes into account the quantity of antibiotics in Grams converted to daily defined dose (DDD) and number of hospitalization days. The daily defined dose (DDD) was proposed by WHO. The calculation of the AD for each molecule was carried out according to the following formula: [AD = Quantity consumed in grams for the particular antimicrobial X 1000]/[DDD for that antimicrobial X number of days hospitalizations]. There was statistically significant relationship between increasing use of ceftazidime and ceftazidime resistant Klebsiella pneumoniae (rs=0.93; p=0.02). The use of ceftazidime was not significantly associated with resistance to this molecule in P. aeruginosa (rs=0.76 ; p=0.13). Concerning the fluoroquinolones, there was statistically significant relation ship between increasing use of ciprofloxacin and rate ciprofloxacin resistant P. aeruginosa (rs=0.89,P=0.043). Furthermore, the consumption of ciprofloxacin was significantly correlated to imipenem resistance in P. aeruginosa (rs=0.87, p=0.05 ). However, the consumption of imipenem was not significantly correlated to resistance of this drug in P. aeruginosa (rs=0.45; P=0

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.

Those practicing Emergency Medicine are frequently faced with a patient presenting with a chemical burn. Most dermal chemical burns are minor and do not require specialized treatment. Occasionally, however, the clinician may be in the position of responding to a chemical burn in which standard therapy of irrigation and good wound care may not be sufficient or, at worst, contraindicated. Several burn conditions will be reviewed, some of those requiring only specific decontamination techniques, as in hot tar, others posing special hazards to clinicians, as in elemental metals, and finally, examples are given of hazardous materials requiring attention to systemic effects, as in hydrofluoric acid.

Inflammation, proliferation, and tissue remodeling are essential steps for wound healing. The hypoxic wound microenvironment promotes cell migration through a hypoxia—heat shock protein 90 alpha (Hsp90α)—low density lipoprotein receptor-related protein-1 (LRP-1) autocrine loop. To elucidate the role of this autocrine loop on burn wound healing, we investigated the expression profile of Hsp90α at the edge of burn wounds and found a transient increase in both mRNA and protein levels. Experiments performed with a human keratinocyte cell line—HaCaT also confirmed above results. 17-dimethylaminoethylamino-17demethoxygeldanamycin hydrochloride (17-DMAG), an Hsp90α inhibitor, was used to further evaluate the function of Hsp90α in wound healing. Consistently, topical application of Hsp90α in the early stage of deep second-degree burn wounds led to reduced inflammation and increased tissue granulation, with a concomitant reduction in the size of the wound at each time point tested (pburn wound management.

More than 50 years ago, Shriners Hospitals for Children expanded their philanthropy to include care for burned children. In so doing, the effects of their work weightily expanded from rehabilitation and quality of life outcomes to include survival proper. As the first facility dedicated to the care of burned children, originally designated the Shriners Burn Institute, the Galveston hospital remains the cornerstone of this endeavor. Shriners maintains charitable pediatric hospitals, provide care irrespective of the patient's or the family's ability to pay, and promote research. The sole criterion for admission at Shriners Hospitals for Children is the determination by a surgeon at a Shriners hospital that "the child's trouble may be corrected or improved." This philanthropic effort to provide medical care for children is one expression of the human commonality recognized by Shriners. In this article, we provide some background information on how this hospital came into existence as well as a global summary of its interventions toward greater survival and more complete rehabilitation of burned children. Based on the findings presented herein, we assert that there is less suffering and less loss of life due to childhood burns today than in previous years. We attribute much of this improvement to the simple voluntary collective decision by Shriners to provide alms for burned children.

Qualitative methods are progressively being implemented by researchers for exploration within healthcare. However, there has been a longstanding and wide-ranging debate concerning the relative merits of qualitative research within the health care literature. This integrative review aimed to exam the contribution of qualitative research in burns care and subsequent rehabilitation. Studies were identified using an electronic search strategy using the databases PubMed, Cumulative Index of Nursing and Allied Health Literature (CINAHL), Excerpta Medica database (EMBASE) and Scopus of peer reviewed primary research in English between 2009 to April 2014 using Whittemore and Knaﬂ's integrative review method as a guide for analysis. From the 298 papers identified, 26 research papers met the inclusion criteria. Across all studies there was an average of 22 participants involved in each study with a range of 6-53 participants conducted across 12 nations that focussed on burns prevention, paediatric burns, appropriate acquisition and delivery of burns care, pain and psychosocial implications of burns trauma. Careful and rigorous application of qualitative methodologies promotes and enriches the development of burns knowledge. In particular, the key elements in qualitative methodological process and its publication are critical in disseminating credible and methodologically sound qualitative research.

Wound matrix materials are used to improve the regeneration of dermal and epidermal layers in both acute and chronic wounds. Contemporary wound matrices are primarily composed of biologic materials such as processed xenogeneic and allogeneic tissues. Unfortunately, existing biologic wound matrices possess multiple limitations including poor longevity, durability, strength, and enzymatic resistance required for persistent support for new tissue formation. A fully-synthetic, resorbable electrospun material (Restrata Wound Matrix, Acera, St.Louis, Missouri ) that exhibits structural similarities to the native extracellular matrix offers a new approach to the treatment of acute and chronic wounds. This novel matrix is the first product to combine the advantages of synthetic construction (e.g. resistance to enzymatic degradation, excellent biocompatibility, strength/durability and controlled degradation) with the positive attributes of biologic materials (e.g. biomimetic architecture similar to human extracellular matrix (ECM), fibrous architecture optimized to support cellular migration and proliferation, engineered porosity to encourage tissue ingrowth and vascularization). These features allow RWM to achieve rapid and complete healing of full-thickness wounds that, in preclinical studies, is comparable to Integra Bilayer Wound Matrix (Integra LifeSciences, Plainsboro, New Jersey), a gold standard biologic material with diverse clinical indications in the wound care. Together, this review suggests that the RWM offers a unique fully-synthetic alternative to existing biologic matrices that is effective, widely available, easy to store, simple to apply and low cost.
Full Text Available Nick Santamaria,1 Suzanne Kapp2 1University of Melbourne and Melbourne Health, Royal Melbourne Hospital, Melbourne, VIC, Australia; 2Royal District Nursing Service Institute, Melbourne, VIC, Australia Abstract: The use of wound telemedicine systems in the home care environment has been expanding for the last decade. These systems can generally be grouped into two main types: store and forward systems and video conference type systems; additionally, there are also hybrid systems available that include elements of both. Evidence to date suggests that these systems provide significant benefits to patients, clinicians, and to the health care system generally. Reductions in resource use, visit substitution, costs, and high patient and clinician satisfaction have been reported; however, there is a lack of integration with existing health care technology and no clearly defined technical or clinical standards as yet. Similarly, the legalities associated with wound telemedicine and remote consultation remain unclear. As wound telemedicine systems continue to evolve and be deployed in different locations, there remains significant potential to harness their power to benefit patients being treated at home.

This bachelor?s thesis deals with the actual classification of wounds and the issue of the chronic wound treatment. In the preface of the theoretical part of the thesis, the term wound is defined and the wounds are subcategorized in the terms of their pathological traumatological origin. In the next chapters, the process of the wound healing is analysed from molecular biological aspect, the terms acute and chronic wound are defined and newly introduces the term non-healing wound for the chron...
Full Text Available For centuries silver and its compounds have been in use to control infection and avoid septicaemia in the care of burns and chronic wounds. Renewed interest has resulted in a number of silver-based dressings exploiting nanotechnology that are now widely employed in burns centers. Despite extensive use, a systematic study of the chemical composition, release kinetics and biochemical action of these products has yet to be published. In this work we have characterized the morphology and elemental composition of a commercial dressings containing Ag by SEM-EDS. The silver content was determined by ICP-MS to be about 1.4 mg cm-2. Release kinetics in ultra pure water, physiological saline solution and human serum substitute were then deeply investigated. The highest release rates were found in serum substitute, with a maximum of 2.6 μg hr-1 cm-2. Our results show that the mean inhibitory concentrations are exceeded for most common pathogens in serum substitute and sterile water, while the presence of high Cllevels inactivates the dressings.

The aims were to explore the lived experience of combat-wounded patients and the military nurses who care for them. The study was a qualitative phenomenological design, and focus groups were conducted with 20 nurses and 8 combat-wounded patients. Themes common to nurses and patients were coping, shared experiences, finding meaning, psychosocial nursing care, families, and bureaucratic structure. Thematic differences were the patients' perspectives "changed self" while nurses described "professional boundaries."

A number of healthcare professionals, specialists in different fields and with different levels of education, as well as non-healthcare professionals, are involved in the care of chronic wound patients, thus forming a multidisciplinary team that is not only responsible for the course and outcome of treatment, but also for the patient quality of life. Family doctor is also member of the team the task of which is to prevent, diagnose, monitor and anticipate complications and relapses, as well as complete recovery of chronic wound patients, with the overall care continuing even after the wound has healed, or is involved in palliative care. A family medicine practitioner with specialized education and their team of associates in the primary health care, along with material conditions and equipment improvement, can provide quality care for patients with peripheral cardiovascular diseases and chronic wounds, organized according to the holistic approach. It is essential that all professional associations of family medicine as well as professional associations of other specialties - fields that are involved in wound prevention and treatment - be included in developing the continuous medical education program. The benefits of modern information technology should be used to good advantage. The education should be adapted to the needs of family practitioners in terms of the form, place, time, volume, financial affordability and choice of topic. The interest shown in team education should be transformed into specialized programs in the creation of which it is essential to include both physicians and nurses and their respective professional associations. Special attention should be paid to education and training of young doctors/nurses, those with less work experience, those that have not yet been part of such education, those that lack experience in working with wound patients, those whose teams deal mostly with elderly patients, and also residents in family medicine and

Full Text Available Aim: Skin burn is a health problem that requires fast and accurate treatment. If not well-treated, the burn will cause various damaging conditions for the patient. The leaf extract of Madeira vine (Anredera cordifolia (Ten. Steenis, or popularly known as Binahong in Indonesia, has been used to treat various diseases. The purpose of this research is to determine the effects of leaf extracts of Madeira vine (A. cordifolia (Ten. Steenis on skin burn healing process in rats as an animal model. Materials and Methods: In this research, there were four treatment groups: G0, G1, G2, and G3, each consisting of five rats. All these rats were given skin burns, using hot metal plates. Then, sulfadiazine was given to G0, 2.5% leaf extract of Madeira vine was given to G1, 5% extract was given to G2, and 10% extract was given to G3, for straight 14 days topically, 3 times a day. At the end of the treatment period, skin excisions were conducted, and histopathological examination was carried out. Results: Microscopic observation on the wound healing process on the collagen deposition, polymorphonuclear infiltration, angiogenesis, and fibrosis showed that G2 had a significant difference with G0, G1, and G3 (p<0.05, while group G0 was significantly different from G1 and G3 (p<0.05. The better burn healing process on G2 allegedly because of the activity of flavonoid, saponin, and tannin, contained in the Madeira vine, which have the antioxidant, anti-inflammatory, and antibacterial effects. Conclusion: The ointment from the 5% leaf extract of Madeira vine (A. cordifolia (Ten. Steenis has been proven to be effective to be used for topical burn therapy.
Conclusion: Cryopreserved allo-CEG contains growth factors that promote wound healing and factors that suppress scarring. Three effects, namely (1 early wound closure, (2 scarring suppression, and (3 pain relief were seen with grafts of cryopreserved allo-CEG in cases of childhood DDB. These observations show that cryopreserved allo-CEG is clinically useful and effective for the treatment of childhood DDB.

Wound healing is the intricate process that restores function to damaged skin. The process consists of the inflammatory, proliferative and remodeling phases that orchestrate dynamic cellular responses to regenerate the cutaneous barrier. However, microbial contamination of the wound site stimulates a deleterious inflammatory response with the production of endotoxins, exotoxins and proteases that result in secondary injury. The end result is delayed healing, protracted debilitation and increased health care costs. Controlling contamination is critical for proper wound management and reduced burden on the healthcare system. Based on this concern, we developed and applied a new antimicrobial therapeutic that relies on hyperosmotic nanoemulsions (HNE). The biomechanical process consists of a high-energy nanoemulsion component that permeates the protective microbial membrane and a (ii) nonionic hyperosmoticum that facilitates intracellular water extraction to critically dehydrate the pathogen. HNE was shown to be effective against a multitude of pathogens including bacteria, antibiotic-resistant variants, fungi and viruses. Reported non-clinical studies demonstrate that the membrane disrupting nanoemulsion and hyperosmotic component act synergistically to enhance microbicidal activity. Further, results illustrate that pathogen inactivation was rapid as determined by ion and macromolecule leakage assays. Application of HNE in a pre-clinical animal model of wound healing demonstrated the treatment actively promoted healing to reduce treatment times. HNE mitigated wound infection to reduce the inflammatory response and mechanically debrided the wound to facilitate wound closure. Recent work further enhanced the stability of the nanoemulsion component with the addition of surfactant stabilizers using a low-energy spontaneous emulsification process. The refined nanoemulsion composition was stable against physical stressors and long-term storage without disrupting the

Buruli ulcer (BU) is a necrotizing skin disease caused by Mycobacterium ulcerans. People living in remote areas in tropical Sub Saharan Africa are mostly affected. Wound care is an important component of BU management; this often needs to be extended for months after the initial antibiotic
Cold atmospheric plasma is an ideal medium for non-destructive modification of vulnerable surfaces. One of the most promising medical applications of cold plasma treatment is wound healing. Potential advantages in wound healing have been demonstrated in vitro: the plasma does not necrotize the cells and does not affect the extracellular matrix , has clear bactericidal or bacteriostatic effects , and stimulates fibroblast cells towards faster attachment and proliferation . However, safety issues, such as the potential cytotoxicity of the plasma must be clarified prior to clinical implementation. This work comprises the recent facts on sub-lethal plasma effects on mammalian cells, as well as studies on apoptosis induction and quantitative assessment of DNA damage. Fibroblast, smooth muscle and endothelial cells were treated using the standard cold plasma needle [1,2]; intra- and extracellular oxidant levels as well as the influence of the plasma on intracellular antioxidant balance were monitored using appropriate fluorescent markers . We have studied long-term cellular damage was monitored using flow cytometry to determine the DNA profiles in treated cells. Dose-response curves were obtained: increased proliferation as well as apoptosis were visualized under different treatment conditions. The results from the in vitro studies are satisfying.  I.E.

Full Text Available Objective: To investigate the knowledge of nursing students about the care provided to patients with neoplastic wound. Method: This is an exploratory research of a qualitative nature, which was attended by 15 students of the Bachelor's Degree in Nursing from the Center of Education and Health of the Federal University of Campina Grande, campus Cuité - PB, in the period from October to November 2015. For data collection, we used a form for an interview. The data were analyzed through the Technique of Thematic Analysis of Minayo. Results: From the analysis of the empirical material emerged the following thematic categories: Category 1 - Defining neoplastic wounds; Category 2 - Knowledge incipient on ‘neoplastic wounds’ for academic and professional practice; Category 3 - Envisioning the theme "neoplastic wound" in the Academy; Category 4 - Knowledge about methods of evaluation of neoplastic wounds and Category 5 - Knowledge of therapeutic modalities of neoplastic wounds. Conclusions: The academics know the evaluative method of a patient with neoplastic wound as integralizadora unit of care process; recognize palliative care as the best therapeutic modality for these customers, especially when they are in completion and indicate the products contraindicated in the treatment of these lesions; however, do not mention the covers and recommended substances for the control of the signs and symptoms of these injuries. In this context, it is believed that the creation of academic projects of extension, with the aim of creating opportunities for integration between theory and practice, is one of the ways to improve the knowledge.

Accurate evaluation of non-healing, chronic wounds followed by the selection of an appropriate therapeutic strategy is a must for the foundation of health-care management. Assessment of non-healing chronic wounds in clinical practice in the Czech Republic is not standardised in acute care settings or in residential social care facilities. The aim of the study was to analyse the methods being used to assess non-healing, chronic wounds in residential social services in the Czech Republic, where more patients with chronic wounds are present because of the increasing incidence of wounds in old age. The research was carried out at 66 residential social care institutions across all regions of the Czech Republic. A mixed model was used for the research (participatory observation including creation of field notes and content analysis of documents for documentation and analysis of qualitative and quantitative data). The same methodology was used in previous work which has been done in acute care settings in 2013. The results of this research have corroborated the inconsistencies in procedures used by general nurses for assessment of non-healing, chronic wounds. However, the situation was found to be more positive with regard to the evaluation of basic/fundamental parameters of a wound (e.g. size, depth and location of the wound) compared with the evaluation of more specific parameters (e.g. exudate or signs of infection). This included not only the number of observed variables, but also the action taken. Both were improved when a consultant for wound healing was present. An effective strategy for wound management depends on the method and scope of the assessment of non-healing, chronic wounds in place in clinical practice in observed facilities; improvement may be expected following the general introduction of 'non-healing, chronic wound assessment' algorithm.

Thermal burn injuries are a significant cause of morbidity and mortality worldwide. In addition to treatment of the burns, emergency clinicians must assess for inhalation injury, exposure to toxic gases, and related traumatic injuries. Priorities for emergency resuscitation include stabilization of airway and breathing, intravenous fluid administration, pain control, and local wound care. Special populations, including children and pregnant women, require additional treatment considerations. Referral to specialized burn care for select patients is necessary to improve long-term outcomes. This article reviews thermal burn classification and evidence-based treatment strategies.

Full Text Available In 1978, a landmark United Nations conference in Alma-Ata declared the goal of health for all by the year 2000 (WHO, 1978. Yet, today significant disparities exist between the health care afforded individuals in resource-limited countries and those in the industrialized world. Nursing, as a global profession, can become a powerful force for change so that better health is universally achieved. Problem/Background: This project started with a partnership between a burn center in the United States and a pediatric burn center (Burn Center in Peru, a country in which it is estimated that 15,000 children endure burn injuries each year (Huby-Vidaurre, 2016. Most are under the age of five, and suffer scald burns from pots with hot liquids left to cool on the floors of their homes. Pressure garment therapy (PGT is a major treatment to reduce scarring for pediatric burn survivors in the United States since the early 1970s, but is unavailable in Peru. Strategy: The Doctor of Nursing Practice project leader worked with the Burn Center team to develop a plan to use PGT as an intervention to address disfiguring scarring among pediatric burn survivors, utilizing the twinning approach. Methods: This quality improvement project involved interdisciplinary collaboration and international partnerships between resource-rich and resource-challenged nations. Obtaining supplies needed to promote PGT in Peru required cultivating relationships with many people in the United States, including translators and interpreters to assist in overcoming language barriers among the participants, manufacturers and distributors of pressure garments to donate fabrics, and people regularly traveling to Peru who transported the donated PGT materials. It also involved working closely with the Burn Center team on developing a culture conducive to conforming to an international standard of practice. Results: Resources were successfully leveraged to build a sustainable PGT program for all

To detect whether chitin and sepia ink sponge (CS) can promote wound healing and elevate impact of CS on phagocytosis ability of macrophages. Forty-eight rats were assigned to four groups: Normal group (Normal), negative control group (Con), chitin and sepia ink sponge group (CS) and positive control Surgicel Gauze(r) group (SG). Deep second-degree burn model was created in rats. Wound area was recorded by digital imaging and determined using Image J software. Samples were collected and kept at -80oC on 3d, 7d, 14d and 21d for cytokines detecting. Transforming growth factor (TGF)-β1, interleukin (IL)-6, matrix metalloproteinase (MMP)-1, hydroxyproline (Hyp) and macrophage activity reflected by tumor necrosis factor (TNF)-α were determined by enzyme-linked immunosorbent assay (ELISA). Comparing to Con and SG, scabs in CS group fell off and basically healed on 21 day. TGF-β1, IL-6, MMP-1 and Hyp were significantly increased by CS and SG comparing to Con (p < 0.05), CS had more apparently adjustment on TGF-β1 and MMP-1 compared to SG; results in vitro indicated CS significantly promoted phagocytosis ability of macrophages reflected in TNF-α (p < 0.05). CS improved wound healing through exerting significant influences on secretion of kinds of cytokines and activating macrophages.

In recent years, Burn Center has evolved to become a "wound intensive care unit" treating disease processes other than those due to thermal injury. Recent data have shown that more than 16% of admissions to Burn Centers are for nonburn injuries, particularly severe dermatologic diseases. The role of the Burn Center has been expanded to include treatment of patients with severe cutaneous manifestations of rheumatologic diseases. This approach has not been described before. All collagen vascular disease admissions to the Burn Center from 2005 to 2010 have been reviewed. There were 16 admissions where intensive wound management was a major component of the disease management. Disease processes included systemic lupus erythematosus, progressive systemic sclerosis, Raynaud's phenomenon, antiphospholipid syndrome, and dermatomyositis, among others. The authors describe five of these cases in detail. Comanagement of these patients by the Rheumatology and Burn services led to outstanding, successful outcomes. Collagen vascular diseases represent another area where the Burn Center may be the appropriate site for therapy.

Metallo-β-lactamase-production among Gram-negative bacteria, including Pseudomonas aeruginosa , has become a challenge for treatment of infections due to these resistant bacteria. The aim of the current study was to evaluate the metallo-β-lactamase-production and carriage of bla- VIM genes among carbapenem-resistant P. aeruginosa isolated from burn wound infections. A cross-sectional study was conducted from September 2014 to July 2015. One hundred and fifty P. aeruginosa isolates were recovered from 600 patients with burn wound infections treated at Imam-Musa-Kazem Hospital in Isfahan city, Iran. Carbapenem-resistant P. aeruginosa isolates were screened by disk diffusion using CLSI guidelines. Metallo-β-lactamase-producing P. aeruginosa isolates were identified using an imipenem-EDTA double disk synergy test (EDTA-IMP DDST). For detection of MBL genes including bla - VIM-1 and bla - VIM-2 , polymerase chain reaction (PCR) methods and sequencing were used. Among the 150 P. aeruginosa isolates, 144 (96%) were resistant to imipenem by the disk diffusion method, all of which were identified as metallo-β-lactamase-producing P. aeruginosa isolates by EDTA-IMP DDST. Twenty-seven (18%) and 8 (5.5%) MBL-producing P. aeruginosa isolates harbored bla- VIM-1 and bla - VIM-2 genes, respectively. Our findings showed a high occurrence of metallo-β-lactamase production among P. aeruginosa isolates in burn patient infections in our region. Also, there are P. aeruginosa isolates carrying the bla - VIM-1 and bla - VIM-2 genes in Isfahan province.

Diagnostic multiplex polymerase chain reaction assay for the identification of Pseudomonas aeruginosa from the skin biopsy specimens in burn wound infections and detection of antibiotic susceptibility
Mashouf, Rasoul Y.; Farahani, Hadi S.; Zamani, A.
Objective was to identify Pseudomonas aeruginosa (P. aeruginosa) from the skin biopsy specimens in burn wound infections by multiplex polymerase chain reaction (M-PCR) and detection of antimicrobial susceptibility of isolates from culture. We conducted the cross-sectional study in 140 patients with wound infections who admitted to referral burn center of Motahari, Tehran, Iran, during a 12-month period from 2005-2006. Skin biopsy specimens were aseptically taken from each patient, one for PCR and one for bacterial culture. A M-PCR test based on simultaneous amplification of 2 lipoprotein genes: oprI and oprL, was used to directly detect fluorescent pseudomonades and P. aeruginosa in skin biopsy specimens. The susceptibility of P. aeruginosa isolates to 16 antibiotics was determined using the disc diffusion method. Out of 140 biopsy specimens, M-PCR detected 66 (47.2%) isolates, while culture detected 57 (40.7%) isolates as P. aeruginosa. Positive results for both genes which observed only for P. aeruginosa, while only one gene, oprI, was amplified from other fluorescent pseudomonades (n=12) and all other bacterial tested (n=62) were negative by the amplification test. The most effective antibiotics against isolate of P. aeruginosa were cefepime (79%), azetreonam (76%), ticarcillin-clavulanic acid (68%), tobramycin (62%) and amikacin (61%). Multiplex PCR assay appears promising for the rapid and sensitive detection of P. aeruginosa from the burned skin biopsy specimens. Simultaneous amplification of 2 lipoprotein genes: oprI and oprL could detect P. aeruginosa and oprI gene only for other fluorescent pseudomonades. (author)

The aim of this systematic review was to determine the supporting evidence for the clinical use of hydrogel dressings as a first aid measure for burn wound management in the pre-hospital setting. Two authors searched three databases (Ovid Medline, Ovid Embase and The Cochrane Library) for relevant English language articles published through September 2014. Reference lists, conference proceedings and non-indexed academic journals were manually searched. A separate search was conducted using the Internet search engine Google to source additional studies from burns advisory agencies, first aid bodies, military institutions, manufacturer and paramedic websites. Two authors independently assessed study eligibility and relevance of non-traditional data forms for inclusion. Studies were independently assessed and included if Hydrogel-based burn dressings (HBD) were examined in first aid practices in the pre-hospital setting. A total of 129 studies were considered for inclusion, of which no pre-hospital studies were identified. The review highlights that current use of HBD in the pre-hospital setting appears to be driven by sources of information that do not reflect the paramedic environment. We recommend researchers in the pre-hospital settings undertake clinical trials in this field. More so, the review supports the need for expert consensus to identify key demographic, clinical and injury outcomes for clinicians and researchers undertaking further research into the use of dressings as a first aid measure. © 2015 Medicalhelplines.com Inc and John Wiley & Sons Ltd.

Negative pressure wound therapy (NPWT) is widely used in the management of acute and chronic wounds. The purpose of this 8-week study was to evaluate outcomes of using a new canisterless, portable, single-use NPWT system in patients with wounds treated in a Canadian community healthcare setting. The device is designed to provide negative pressure at 80±20 mm Hg, 24 hours a day of continuous usage, for a maximum wear time of 7 days. Data on wound outcomes, including exudate levels, wound appearance, and wound area, were collected weekly by a Registered Nurse as part of routine practice. When treatment was discontinued, patients and nurses were asked to rate their satisfaction with the device. Data from patients who had used a conventional NPWT device to manage their wounds were retrospectively abstracted from their medical records. In the prospective study, conducted between October 2011 and July 2012, 326 patients (median age=61 years; range 17-91 years) with wounds of mixed etiology (53 pressure ulcers, 21 venous leg ulcers, 16 diabetic foot ulcers, and 15 traumatic and 221 surgical wounds) were treated for a maximum of 8 weeks with the portable NPWT device. The majority of patients (228 out of 326; 68%) achieved complete wound closure within 8 weeks of treatment. The Kaplan-Meier estimate of median time to healing of all wounds was 9 weeks. The majority of patients (318 patients, 97%) reported they were pleased or satisfied with the dressing performance. Nurses indicated satisfaction with the dressing performance for all but two patients (99%). The majority (89%) of patients managed with conventional NPWT (n=539) had an open surgical wound with moderate or high levels of exudate. Healing rates in the portable and conventional NPWT group were similar (10% to 11% per week). Portable, single-use NPWT has the potential to deliver good wound outcomes in community care settings and simplify the use of negative pressure for nurses and patients. Additional research is
Full Text Available Wound healing is an intricate process that requires complex coordination between many cells and an appropriate extracellular microenvironment. Chronic wounds often suffer from high protease activity, persistent infection, excess inflammation, and hypoxia. While there has been intense investigation to find new methods to improve cutaneous wound care; the management of chronic wounds, burns, and skin wound infection remain challenging clinical problems. Ideally, advanced wound dressings can provide enhanced healing and bridge the gaps in the healing processes that prevent chronic wounds from healing. These technologies have great potential for improving outcomes in patients with poorly healing wounds but face significant barriers in addressing the heterogeneity and clinical complexity of chronic or severe wounds. Active wound dressings aim to enhance the natural healing process and work to counter many aspects that plague poorly healing wounds including excessive inflammation, ischemia, scarring and wound infection. This review paper discusses recent advances in the development of biomaterials and nanoparticle therapeutics to enhance wound healing. In particular, this review focuses on the novel cutaneous wound treatments that have undergone significant preclinical development or currently used in clinical practice.

Full Text Available This paper reports on the findings of a user trial of a mHealth application for pressure ulcer (bedsore documentation. Pressure ulcers are a leading iatrogenic cause of death in developed countries and significantly impact quality of life for those affected. Pressure ulcers will be an increasing public health concern as the population ages. Electronic information systems are being explored to improve consistency and accuracy of documentation, improve patient and caregiver experience and ultimately improve patient outcomes. A software application was developed for Android Smartphones and tablets and was trialed in a personal care home in Western Canada. The software application provides an electronic medical record for chronic wounds, replacing nurses’ paper-based charting and is positioned for integration with facility’s larger eHealth framework. The mHealth application offers three intended benefits over paper-based charting of chronic wounds, including: (1 the capacity for remote consultation (telehealth between facilities, practitioners, and/or remote communities, (2 data organization and analysis, including built-in alerts, automatically-generated text-based and graph-based wound histories including wound images, and (3 tutorial support for non-specialized caregivers. The user trial yielded insights regarding the software application’s design and functionality in the clinical setting, and highlighted the key role of wound photographs in enhancing patient and caregiver experiences, enhancing communication between multiple healthcare professionals, and leveraging the software’s telehealth capacities.

Burns are injuries caused by direct or indirect contact to chemical, physical, or biological agents. Low-level laser therapy (LLLT) is a promising treatment since it is low-cost, non-invasive, and induces cell proliferation. This study aimed to investigate the effects of LLLT (660 nm) at two different fluences (12.5 J/cm(2) and 25 J/cm(2) ) per point of application on third-degree burns in rats. Thirty rats (Wistar) divided into GC, GL12.5, and GL25 were used in the study, and submitted to burn injury through a soldering iron at 150°C, pressed on their back for 10 s. LLLT was applied immediately, and 2, 4, 6, and 8 days after wound induction. Histological analysis revealed a decreased inflammatory infiltrate in the group treated with 25 J/cm(2) , and intense inflammatory infiltrate in the control group and in the group treated with 12.5 J/cm(2) . The immunostaining of COX-2 was more intense in the control groups and in the group treated with 12.5 J/cm(2) than in the group treated with 25 J/cm(2) . Conversely, VEGF immunomarking was more expressive in the group treated with 25 J/cm(2) than it was in the other two groups. Therefore, our findings suggest that the use of 25 J/cm(2) and 1 J of energy was more effective in stimulating the cellular processes involved in tissue repair on third-degree burns in rats by reducing the inflammatory phase, and stimulating angiogenesis, thus restoring the local microcirculation which is essential for cell migration. © 2016 Wiley Periodicals, Inc.

This study was a randomized-controlled trial comparing the standard type of dry dressing, Mepore, with moist wound healing, using a hydrofiber dressing, Aquacel, in primary closed wounds after vascular surgery. The endpoints were patient comfort, cost-effectiveness, infections, wound complications....... No difference in the infection rate (13% vs. 11%, p=0.73), length of hospital stay, or wound complications was noted between the two groups. We conclude that although the Aquacel dressing needed significantly fewer changes than the conventional dressing, this did not influence the patient comfort. Moreover...

BACKGROUND:: A contributing factor to development of malignant wounds is patient-related delay caused by health care avoidance. OBJECTIVE:: The purpose of this study was to describe the experience of health care avoidance in women with advanced breast cancer who have developed malignant wounds....... RESULTS:: The women deliberately avoided health care for a median of 24 months (minimum, 3 months; maximum, 84 months). Despite being aware of the development of a malignant wound from a breast lump, the women avoided health care because of negative health care experiences and extremely burdening life...... situations. The women did not seek health care until their situations became unmanageable. The essence-"an avalanche of ignoring"-is pointing to the escalating, powerful development of destructive feelings behind health care avoidance. CONCLUSIONS:: Health care avoidance may be a way of coping both for women...
Full Text Available This study aimed to analyze accounts of nurses who undertake the dressing of fungating wounds of women with breast cancer, and to outline contributions to the nursing care. This is qualitative research, carried out in November 2010 with interviews and thematic analysis involving five nurses from the outpatient department of a public hospital in the city of Rio de Janeiro, specializing in the treatment of breast cancer. Categories were elaborated corresponding to the practice of outpatient nursing; the cancer wound; and, indications for the nursing care. It is concluded that there is a need for specific knowledge in the area of oncology nursing, professional involvement, technical skill and autonomy, the forming of a therapeutic group, clinical attendance interfacing with the palliative approach, and collaborative work as a team.

Skin changes caused by aging increase the risk of skin damages, such as pressure ulcers, during hospitalization of elderly patients. There is few information about the cost of wound treatment in Brazil. Conversely, skin and wound problems are highly reported among hospitalized elderly patients and caregivers. The purpose is to analyze the socio-demographic and clinical profile associated with skin and wound care in hospitalized elderly. This is a prospective observational study. The sample consisted of 75 patients, aged 60 years or more, randomly selected in three hospitals in Rio de Janeiro, Brazil. Data extraction from nursing records of the sample, using cross mapping with Nursing Interventions Classification. Data Synthesis supported by SAS 6.11 (SAS Institute, Inc. Cary North Carolina) in association with SPSS version 14.0 and statistics analysis. The findings were: age standard deviation 7.8, with minimum as 60, and maximum as 91 years old. Prevalence of women and married seniors. High prevalence of long-term hospitalization. There were 21 Nursing Interventions in the nursing records and seventeen of them related to skin and wound care. They were described in 57 nursing activities, present during 376 evaluations and repeated 1756 times. A significant difference was obtained between age and the presence of the nursing interventions "Positioning" (p-0.004), Eye Care/Hygiene (p- < 0.0001) and Oral Health Maintenance (p-0.0003). The skin care to prevention and treatment of skin damages represented the major demand of nursing interventions in different clinical conditions of hospitalized elderly.

Pediatric tracheostomy is commonly performed for upper airway obstruction and prolonged mechanical ventilation. Children undergoing tracheostomy typically have multiple chronic medical problems that place them at high risk for readmission and additional complications. To determine whether the institution of a postoperative protocol for parent education and wound care with a nurse trained in tracheostomy care decreases the rate of readmission and other complications. A case series and medical record review was conducted of children 18 years and younger who underwent tracheostomy at a tertiary pediatric medical center between January 1, 2009, and December 31, 2014. A postoperative tracheostomy care and education protocol. Overall 30-day readmission rate, 30-day tracheostomy-related readmission rate, tracheostomy wound complications, and additional factors that may have affected readmission rates and wound complications (age at the time of tracheostomy, discharge location, indication for tracheostomy). A total of 191 children (118 boys and 73 girls) were included; of these, 112 participated in the education protocol and 79 children did not. Following institution of the education protocol, there was no decrease in the overall readmission rate (26.8% before the protocol vs 26.6% after the protocol; difference, 0.2%; 95% CI, -12.5% to 13.0%) or in the tracheostomy-related readmission rate (10.1% before the protocol vs 7.1% after the protocol; difference, 3.0%; 95% CI, -5.0% to 11.0%). Overall, 68.6% of readmissions were associated with medical comorbidities (95% CI, 55.9% to 81.3%). There was a significant decrease in tracheostomy-related wound complications after institution of the protocol (31.6% to 17.9%; difference, 13.7%; 95% CI, 1.6% to 26.0%). Multiple logistic regression analysis showed that children who were discharged home were significantly more likely to be readmitted for a tracheostomy-related complication than were patients discharged to an advanced care

The purpose of this study was to determine whether nurses could use a structured intervention to educate patients with wounds about foods that promote healing and whether this educational intervention could be provided in a cost-effective manner. Cross-sectional survey. The study was conducted at an outpatient wound care center located on a hospital campus in the Southern United States; 3 full-time nurses and 2 nurses employed on part-time status delivered the intervention. A nutrition education intervention was developed through collaborative efforts of a registered dietitian and a nurse. A cross-sectional survey design was used to (1) evaluate nurses' perceptions of the intervention and (2) identify barriers to implementation of the intervention. Direct costs related to materials and nursing time required to deliver the intervention were calculated. Participants indicated they were competent to deliver the structured intervention, and all were willing to continue its use. Survey results indicated that nurses believed the intervention was beneficial to their patients and they indicated that patients were responsive to the intervention. The intervention was found to be low cost ($8.00 per teaching session); no barriers to implementation of the intervention were identified. The results of this exploratory study suggest that a structured nutrition education intervention can be provided by nurses in outpatient wound clinics at low cost. Further study is needed to determine the impact of this intervention on nutritional intake and wound healing.

In military medicine, one of the challenges in dealing with large combat-related injuries is the prevalence of bacterial infection, including multidrug resistant organisms. This can prolong the wound healing process and lead to wound dehiscence. Current methods of identifying bacterial infection rely on culturing microbes from patient material and performing biochemical tests, which together can take 2-3 days to complete. Surface Enhanced Raman Spectroscopy (SERS) is a powerful vibrational spectroscopy technique that allows for highly sensitive structural detection of analytes adsorbed onto specially prepared metal surfaces. In the past, we have been able to discriminate between bacterial isolates grown on solid culture media using standard Raman spectroscopic methods. Here, SERS is utilized to assess the presence of bacteria in wound effluent samples taken directly from patients. To our knowledge, this is the first attempt for the application of SERS directly to wound effluent. The utilization of SERS as a point-of-care diagnostic tool would enable physicians to determine course of treatment and drug administration in a matter of hours.

Patients' perceptions of their physician can affect subjective and objective outcomes. Physician attire influences patients' perceptions of their physician and consequently may affect patient outcomes. To determine patient preferences for different types of dermatologist attire in dermatology medical, surgical, and wound care clinics. We hypothesized that patients in the dermatology medical setting would prefer professional attire, while patients in the dermatology surgical and wound care setting would prefer surgical scrubs. This study analyzed responses to a cross-sectional, anonymous survey by English-speaking dermatology patients (aged 18 years or older) at general, surgical, and wound care clinics in an academic center in Miami, Florida. Patients who could not read and understand the survey were excluded. Participants received pictures of a physician wearing business attire, professional attire, surgical attire, and casual attire, and responded by indicating which physician they preferred for each of 19 questions. Frequencies of responses were recorded, and χ2 and regression tests were performed. Response frequencies. Surveys were administered to 261 persons, and 255 participated and completed enough of the questions to be included in the outcome analyses (118 men, 121 women, 22 unknown [did not answer sex question]), mean (SD) age, 56.3 (18.6) years; about 49% of those who reported their sex were men; 56% were Hispanic; and 85% were white. Approximately 72% of respondents held a college degree or higher. About 63%, 24%, and 13% of respondents were medical, surgical, and wound care dermatology patients, respectively. Roughly 73%, 19%, 6%, and 2% of cumulative responses were for professional, surgical, business, and casual attire, respectively. Respondents who received a picture of a black male or black female physician were more likely to exclusively prefer professional attire: unadjusted odds ratios (ORs) 3.21 (95% CI, 1.39-7.42) and 2.78 (95% CI, 1

To study the material and nursing costs and outcome of wound care at home comparing two dressing groups (occlusive vs. gauze-based) in surgical patients after hospital dismissal. The large variety in dressing materials and lack of convincing evidence make the choice for optimum local wound care at home cumbersome. Occlusive wound dressings require a lower change frequency than gauze-based dressings, which appears especially useful for homecare patients and could save costs. We investigated a consecutive series of 76 patients with wounds, included in a randomized trial comparing occlusive vs. gauze dressings. Daily dressing change frequency, consumption of dressing materials and need for district nursing visits were recorded until wound closure by means of diaries and at outpatient visits. Costs were expressed as means and 95% confidence intervals (CI) after calculation using non-parametric bootstrapping. Patient groups were similar regarding age, wound size and aetiology. Dressing change frequency in the occlusive group (median: 0.6/day) was significantly (p = 0.008) lower than in the gauze group (1.1/day). Mean daily material costs of modern dressings were euro5.31 vs. euro0.71 in the gauze group. Mean difference; euro4.60 (95% CI, euro2.68-euro6.83) while daily total (material plus nursing) costs showed no difference between the groups; mean euro2.86 (95% CI, euro-6.50-euro10.25). Wound healing in the gauze-treated group tended to be quicker than in the occlusive dressing group (medians: 30 vs. 48 days, respectively; log-rank p = 0.060). The use of occlusive dressings does not lead to a reduction in costs and wound healing time as compared with gauze dressings for surgical patients receiving wound care at home. District nurses should reconsider using gauze-based dressings, particularly in surgical patients with exudating wounds.

Objective PICC line use for central venous access in thermally injured patients has increased in recent years despite a lack of evidence regarding safety in this patient population. A recent survey of invasive catheter practices among 44 burn centers in the United States found that 37% of burn units use PICC lines as part of their treatment protocol. The goal of this study was to compare PICC associated complication rates to existing literature in both the critical care and burn settings. Methods A single institution retrospective cohort review of patients who received a PICC line during admission to a regional burn unit between 2008–2013. Fifty-three patients were identified with a total of seventy-three PICC lines. The primary outcome measurement for this study was indication for PICC line discontinuation. Results The most common reason for PICC line discontinuation was that the line was no longer indicated (45.2%). Four cases of symptomatic upper extremity deep vein thrombosis (5.5%) and 3 cases of central line associated bloodstream infection (4.3%, 2.72 infections per 1000 line days) were identified. PICC lines were in situ an average of 15 days [range 1–49 days]. Conclusions We suggest that PICC line associated complication rates are similar to those published in the critical care literature. Though these rates are higher than those published in the burn literature, they are similar to CVC associated complication rates. While PICC lines can be a useful resource in the treatment of the thermally injured patient, they are associated with significant, and potentially fatal risks. PMID:25501778

A retrospective national claims database analysis evaluated total and wound-related costs (eg, hospital readmission rates) for patients with chronic wounds treated with negative pressure wound therapy (NPWT), comparing NPWT-V (V.A.C. Therapy, KCI, an Acelity company, San Antonio, TX) and NPWT-O (other non-KCI models of NPWT, the brands of which were not known to the researchers). Patients with ≥ 1 NPWT claim from January 2009-June 2012 in outpatient settings in the United States were included, if they had continuous medical and pharmacy benefits for 12 months before the initial index date of their NPWT claim and at least 3 months post index. Mean total health care costs were assessed at 3 months and 12 months; wound-related hospital readmission rates were assessed at 3 months and 6 months. Cost differences between cohorts were analyzed by t test and readmission rates were analyzed by chi-square test. At 3 months, the cohort of NPWT-V patients was significantly younger (59.2 vs 63.6 years, P assessment, mean comorbidity scores did not differ between the NPWT-V group and the NPWT-O groups (3.38 vs 3.66). Total costs were lower for NPWT-V vs NPWT-O at 3 months ($35,498 vs $39,722, respectively; P = 0.08) and 12 months ($80,768 vs $111,212; P = 0.03). Significantly lower inpatient (P = 0.01), emergency room (P Wound-related readmission rates were significantly lower for NPWT-V at 3 months (5% vs 8%; P ≤ 0.01) and 6 months (6% vs 11%; P ≤ 0.01). For all wound types, NPWT-O patients had a 17-fold higher rate of switching to alternate NPWT models compared with NPWT-V patients. In this retrospective analysis, NPWT-V patients had lower total costs, lower wound-related costs, and lower hospital readmission rates than NPWT-O patients at all time points assessed.

To enhance the liquor absorptivity of chitosan fibers (CS-Fs), N-succinyl surface-modified chitosan fibers (NSCS-Fs) were developed and evaluated for wound healing. The NSCS-Fs exhibited cracks on the surface and high liquor absorbing capacity with absorbing-dissolvable equilibrium state in phosphate buffer solution (PBS). The bacteriostasis ratios of NSCS-Fs against E. coli, S. aureus and C. albicans were higher than 80%. No cytotoxicity has been found for mouse embryo fibroblasts (MEFs) treated with NSCS-Fs leach liquor. Acute oral toxicity and skin irritation experiment were taken to evaluate the safety of NSCS-Fs in vitro. Muscle implant study showed that NSCS-Fs were biodegradable and non-toxic in vivo. These results suggested that the surface modified NSCS-Fs had favorable biological properties and improved liquor absorptivity, indicating that they could be used as promising dressing materials for wound care.

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

Stevens-Johnson syndrome and toxic epidermal necrolysis are rare, life-threatening, cutaneous drug reactions. Medications are the most common cause, although an infection may be responsible. A link between genetics and certain medications has been established. Clinical diagnosis should be confirmed with biopsy. When the area of epidermal detachment approaches 30%, burn center care is advisable. An ophthalmologist should be consulted to optimize ocular care. Pharmacologic interruption has been sought but there is little consensus on the most appropriate agent and no high-quality studies have been conducted to demonstrate if any of these agents lead to improved survival.

Background and Objective. Early burn scar removal is the standard of care for burn patients; excisional debridement, however, often leads to excision of dermal remnants, making autografting unavoidable. Enzymatic debridement with proteolytic enzymes enriched in Bromelain (Nexobrid®) leaves these dermal remnants to allow spontaneous healing of partial thickness burns. This study evaluates if Nexobrid® (MediWound Ltd., Israel) reduces the need for surgery and autografting in intermediate and de...

This study analyses staphylococcal septicaemia in a series of 1516 burn patients who were admitted to the burn unit of the Al-Babtain Centre for Burns and Plastic Surgery, Ibn Sina Hospital, Kuwait over a period of 6.5 years (1 June 1992-31 December 1998). One hundred and nine patients (7.2%) developed clinically and microbiologically proven septicaemia, of which 80 (73.4%) showed one or the other type of Staphylococcus in their blood. Fifty (62.5%) of them were males and 30 (37.5%) females, with a mean age of 26 years and the mean total body surface area of burns (TBSA) of 45% (range 1-93%). Preschool age children comprised 27.5% of the patients. Flame was the dominant (80%) cause of burn. Of the 80 patients who had 91 episodes of septicaemia, 52 (65%) had MRSA, 8 (10%) MSSA, 11 (13.8%) MRSE and 5 (6.2%) MSSE and 4 (5%) others had mixed organisms. Only the patients with MRSA had multiple episodes. Eight patients (10%) showed septicaemic episodes within only 48 h of admission; however, the majority of the patients (77.5%) had a septicaemic attack within 2 weeks postburn. Of the 52 MRSA septicaemic cases, 39 (75%) survived and 13 (25%) died. Four patients with septicaemia due to mixed infections died. A total of 19 patients were intubated, 14 due to inhalation injury and 5 because of septicaemia; all in the former group died. Glycopeptide therapy (vancomycin/teicoplanin) was instituted immediately following the detection of staphylococci in the blood. No significant difference was noted in relation to mortality amongst the septicaemic patients, whether or not on prophylactic antibiotic. Fifty-six (70%) of the 80 patients had 139 sessions of skin grafting and survived. Of the 52 MRSA patients, 40 had 101 sessions of skin grafting and 33 of them survived. The apparent low mortality was probably due to early detection of the organism, appropriate antibiotic therapy, care for nutrition and early wound cover. This study indicates a high incidence of staphylococcal

Full Text Available Abstract Background Fenoldopam mesylate is a highly selective dopamine-1 receptor agonist approved for the treatment of hypertensive emergencies that may have a role at low doses in preserving renal function in those at high risk for or with acute kidney injury (AKI. There is no data on low-dose fenoldopam in the burn population. The purpose of our study was to describe our use of low-dose fenoldopam (0.03-0.09 μg/kg/min infusion in critically ill burn patients with AKI. Methods We performed a retrospective analysis of consecutive patients admitted to our burn intensive care unit (BICU with severe burns from November 2005 through September 2008 who received low-dose fenoldopam. Data obtained included systolic blood pressure, serum creatinine, vasoactive medication use, urine output, and intravenous fluid. Patients on concomitant continuous renal replacement therapy were excluded. Modified inotrope score and vasopressor dependency index were calculated. One-way analysis of variance with repeated measures, Wilcoxson signed rank, and chi-square tests were used. Differences were deemed significant at p Results Seventy-seven patients were treated with low-dose fenoldopam out of 758 BICU admissions (10%. Twenty (26% were AKI network (AKIN stage 1, 14 (18% were AKIN stage 2, 42 (55% were AKIN stage 3, and 1 (1% was AKIN stage 0. Serum creatinine improved over the first 24 hours and continued to improve through 48 hours (p p p p = NS. Modified inotrope score and vasopressor dependency index both decreased over 48 hours (p p = 0.0012. Conclusions These findings suggest that renal function was preserved and that urine output improved without a decrease in systolic blood pressure, increase in vasoactive medication use, or an increase in resuscitation requirement in patients treated with low-dose fenoldopam. A randomized controlled trial is required to establish the efficacy of low-dose fenoldopam in critically ill burn patients with AKI.

The Advanced Burn Life Support (ABLS) program is a burn-education curriculum nearly 30 years in the making, focusing on the unique challenges of the first 24h of care after burn injury. Our team applied high fidelity human patient simulation (HFHPS) to the established ABLS curriculum. Our hypothesis was that HFHPS would be a feasible, easily replicable, and valuable adjunct to the current curriculum that would enhance learner experience. This prospective, evidenced-based practice project was conducted in a single simulation center employing the American Burn Association's ABLS curriculum using HFHPS. Participants managed 7 separate simulated polytrauma and burn scenarios with resultant clinical complications. After training, participants completed written and practical examinations as well as satisfaction surveys. From 2012 to 2013, 71 students participated in this training. Simulation (ABLS-Sim) participants demonstrated a 2.5% increase in written post-test scores compared to traditional ABLS Provider Course (ABLS Live) (p=0.0016). There was no difference in the practical examination when comparing ABLS-Sim versus ABLS Live. Subjectively, 60 (85%) participants completed surveys. The Educational Practice Questionnaire showed best practices rating of 4.5±0.7; with importance of learning rated at 4.4±0.8. The Simulation Design Scale rating for design was 4.6±0.6 with an importance rating of 4.4±0.8. Overall Satisfaction and Self-Confidence with Learning were 4.4±0.7 and 4.5±0.7, respectfully. Integrating HFHPS with the current ABLS curriculum led to higher written exam scores, high levels of confidence, satisfaction, and active learning, and presented an evidenced-based model for education that is easily employable for other facilities nationwide.

(1) The number of funded project were 581 in H15 of NSFC during 2010-2013, total funding reached to 277.13 million RMB, including 117 projects in H1511 (emergency and intensive care medicine/trauma/burns/plastic surgery and other science issue), 96 projects in H1507 (wound healing and scar), 88 projects in H1502 (multi-organ failure), 71 projects in H1505 (burn), 61 projects in H1504 (trauma). (2) The top 10 working unit for project funding in the field of emergency and intensive care medicine/trauma/burns/plastic surgery present as Third Military Medical University (70), Shanghai Jiao tong University (69), Second Military Medical University (40), Chinese PLA General Hospital (36), Forth Military Medical University (35), Zhejiang University (22), Sun Yat-Sen University (18), Southern Medical University (14), China Medical University (11), Capital Medical University (11) respectively, the number of funded project positive correlated with funding. (3) The funded research field in H15 covered almost all important organs and system injury or repair research, our scientists reached a fairly high level in some research field, for example, sepsis, trauma, repair, et al. "Sepsis" was funded 112 projects in H15 for 4 years, the growth rate became rapid and stable comparing to shock, burns and cardiopulmonary resuscitation funded projects

Pediatric burn injuries present a major challenge to the health care team, but an orderly, systematic approach can simplify the initial stabilization and management. A clear understanding of the pathology of burn injuries is essential in providing quality burn care in the prehospital setting and at the referring hospital. After the patient has been rescued from the offending agent, assessment of the burn victim begins with the primary survey and life-threatening injuries initially addressed first. This is followed by a secondary survey to document and treat other injuries or problems. Intravenous access may be established in concert with the local/regional medical control and appropriate fluid resuscitation begun. Burn wounds should be covered with clean, dry sheets, and the patient kept warm with blankets to prevent hypothermia. The patient should be transported to the local hospital ED in the most appropriate mode available. At the local hospital, it should be determined if the burn patient needs burn center care, using the ABA Guidelines. In preparing for and organizing the transfer of the burn victim, consideration must be given to the continued monitoring and management of the patient during transport. In transferring burn patients the same priorities developed for the prehospital management are still operative. During the initial assessment and treatment and throughout the transport, an adequate airway, breathing, circulation, fluid resuscitation, urine output, and pain control must be assured. Ideally, transport of burn victims will occur through and organized, protocol driven plan that includes specialized transport mechanisms and personnel. Successful transport of burn victims, whether in the pre-hospital phase or during inter-hospital transfer, requires careful attention to treatment priorities, protocols, and attention to detail.

The author shows that surgery with craniocerebral injuries should be fully performed at the stage of specialized medical care. Wounded have to be evacuated not earlier than 5-7 days after surgery with the mandatory use of a special air transport ("Scalpel" or "Spasatel"), accompanied by Anaesthetist. In the absence of the possibility of surgery in 5-7 days at this stage the wounded have to be evacuated by air to the center hospitals. On the stage there are only patients requiring specialized care because of health reasons. Wounded with gunshot wounds of the soft tissues of the head, and those with mild forms of brain damage during the explosive and combat injury (concussion, mild brain contusion) can be evacuated by air transport accompanied by a doctor or paramedic at any period of time after the injury (trauma).

Chronic wounds, including pressure ulcers, compromise the health of 6.5 million Americans and pose an annual estimated burden of $25 billion to the U.S. health care system. When treating chronic wounds, clinicians must use meticulous documentation to determine wound severity and to monitor healing progress over time. Yet, current wound documentation practices using digital photography are often cumbersome and labor intensive. The process of transferring photos into Electronic Medical Records (EMRs) requires many steps and can take several days. Newer smartphone and tablet-based solutions, such as Epic Haiku, have reduced EMR upload time. However, issues still exist involving patient positioning, image-capture technique, and patient identification. In this paper, we present the development and assessment of the SnapCap System for chronic wound photography. Through leveraging the sensor capabilities of Google Glass, SnapCap enables hands-free digital image capture, and the tagging and transfer of images to a patient's EMR. In a pilot study with wound care nurses at Stanford Hospital (n=16), we (i) examined feature preferences for hands-free digital image capture and documentation, and (ii) compared SnapCap to the state of the art in digital wound care photography, the Epic Haiku application. We used the Wilcoxon Signed-ranks test to evaluate differences in mean ranks between preference options. Preferred hands-free navigation features include barcode scanning for patient identification, Z(15) = -3.873, p Haiku, the SnapCap System was preferred for sterile image-capture technique, Z(16
