RESUMO

OBJECTIVE: To determine the effects of short bouts of ergometric exercises on the number of days in the burn intensive care unit (ICU), body mass, and functional ambulation. DESIGN: Multi-center, randomized controlled trial. SETTING: Burn intensive care unit. PARTICIPANTS: Children ages 7-17 with severe burns covering over 30% total body surface area (TBSA). INTERVENTION: All patients received standard of care (Control) with the experimental group receiving additional exercise with a cycle ergometer (Exercise). MAIN MEASURES: The number of days in the ICU, total weight, lean body mass (LBM), and functional ambulation were taken shortly after randomization and again within one week of the scheduled hospital discharge. Results of outcomes are expressed as median ± interquartile range (IQR), unless otherwise noted (e.g. demographics). RESULTS: Fifty-four severely burned children (n = 18 Control, n = 36 Exercise) were included. The average ± standard deviation for age was 12 ± 3 years and TBSA was 48 ± 16%. The median ± IQR ICU days for Control was 46 ± 51 days vs 31 ± 29 days for Exercise. The median total weight loss for Control was 2.2 ± 1.2 kg vs 1.8 ± 1.4 kg in Exercise. Control lost 0.75 ± 0.8 kg of LBM vs 0.46 ± 0.43 kg in Exercise. Both groups showed significant improvement in functional ambulation (p < 0.01). However, exercise did not add additional benefits. CONCLUSION: Short bouts of ergometric exercises are feasible for severely burned patients while receiving care in the ICU but did not add additional benefits.

RESUMO

BACKGROUND: As the cost of healthcare rises, it is imperative to assess value delivered to patients and impact on the economic viability of institutions. We aimed to characterize plastic surgery operative time management and identified areas for efficiency improvement. METHODS: Procedures from a US academic plastic surgery division from September 2017 to August 2018 were reviewed. Times were categorized into preparation (patient in room to incision), procedure (incision to closure), exit (closure to patient exiting room), and turnover (patient out of room to next patient in room). Median and interquartile ranges were calculated. Procedures were classified by relative value units (RVUs) for comparison of procedure complexities and resources. Components were plotted against RVUs; r2 values were calculated. RESULTS: We analyzed 522 cases; 69 were excluded for missing data, primary surgeon not a plastic surgeon, emergent cases, or burn procedures; a total of 453 cases were analyzed. Median and interquartile range (in minutes) for preparation was (34, 18 minutes; 23% of total), procedure (53, 75 minutes; 36% of total), exit (30, 27 minutes; 20% of total), and turnover (30, 26 minutes; 20% of total). Normalized to RVUs, preparation demonstrated the most variability (r2 = 0.19), followed by exit (r2 = 0.38), and procedure (r2 = 0.57). Average work RVUs per month was 678.1 ± 158.7. Average work RVUs per OR hour was 7.2. CONCLUSIONS: The largest component with greatest variability was preparation for surgery in the OR. Improved efficiency by decreasing variability increases the value of healthcare delivered to patients and OR throughput.

RESUMO

Burn wound conversion refers to the phenomenon whereby superficial burns that appear to retain the ability to spontaneously heal, convert later into deeper wounds in need of excision. While no current treatment can definitively stop burn wound conversion, attempts to slow tissue damage remain unsatisfactory, justifying the need for new therapeutic interventions. To attenuate burn wound conversion, various studies have targeted at least one of the molecular mechanisms underlying burn wound conversion, including ischemia, inflammation, apoptosis, autophagy, generation of reactive oxygen species, hypothermia, and wound rehydration. However, therapeutic strategies that can target various mechanisms involved in burn wound conversion are still lacking. This review highlights the pathophysiology of burn wound conversion and focuses on recent studies that have turned to the novel use of biologics such as mesenchymal stem cells, biomaterials, and immune regulators to mitigate wound conversion. Future research should investigate mechanistic pathways, side effects, safety, and efficacy of these different treatments before translation into clinical studies.

RESUMO

OBJECTIVE: Stevens-Johnson syndrome (SJS) and its more severe counterpart, toxic epidermal necrolysis (TEN), are skin hypersensitivity reactions defined by epidermal blistering and necrosis. The exact pathophysiology of SJS/TEN is yet to be deciphered, but a number of risk factors have been identified including adverse drug reactions. The diagnosis of SJS/TEN is made on a clinical basis, and treatment consists of supportive care and occasionally immunosuppressants, such as cyclosporin, high-dose intravenous immunoglobulins and/or corticosteroids. Mortality rates can reach 20-25% in adults but are reduced with early intervention. To identify optimal treatment regimens, to better understand the patient cohort affected, and to help identify key risk factors for mortality, we report our experience with the treatment and management of SJS/TEN patients. METHODS: A retrospective review of consecutive patients with SJS and/or TEN admitted to a single burns centre in Germany, between 2008 and 2018, was conducted. The primary outcomes of demographics, clinical course, treatment and patient-reported outcomes were recorded and compared with a control group of patients with burns without a diagnosis of SJS/TEN. RESULTS: A total of 23 patients with SJS/TEN met the inclusion criteria: 17 (74%) with TEN; four (17%) with SJS/TEN overlap; and two (9%) with SJS. Of the patients, 14 (61%) were female and nine (39%) were male. Patient age ranged from 32-78 years (mean: 52 years). A matched cohort of 23 patients with burns served as the control group. All patients received standard of care with a multidisciplinary team. Compared with the control group, SJS/TEN patients had higher mortality rates (n=6, 26% versus n=8, 35%, respectively). The average age of death was 69 years in SJS/TEN patients versus 63 years in control group patients. Age and SCORTEN scores were significant predictors of mortality. CONCLUSIONS: SJS and TEN are rare but extreme reactions of the skin and mucosa, associated with high disease mortality rates. This 10-year single-centre retrospective review contributes to the bank of information for reviews evaluating the management of SJS/TEN patients.

RESUMO

OBJECTIVE: Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) are rare and severe skin and mucosal reactions that are associated with high mortality. Despite the severity, an evidence-based treatment protocol for SJS/TEN is still lacking. METHOD: In this systematic review and meta-analysis, the PubMed database was searched using the following terms: [Stevens-Johnson syndrome] OR [toxic epidermal necrolysis] AND [therapy] OR [treatment] over a 20-year period (1999-2019) in the German and English language. All clinical studies reporting on the treatment of SJS/TEN were included, and epidemiological and diagnostic aspects of treatment were analysed. A meta-analysis was conducted on all comparative clinical studies that met the inclusion criteria. RESULTS: A total of 88 studies met the inclusion criteria, reporting outcomes in 2647 patients. Treatment was either supportive or used systemic corticosteroid, intravenous immunoglobulin, plasmapheresis, cyclosporine, thalidomide or cyclophosphamide therapy. The meta-analysis included 16 (18%) studies, reporting outcomes in 976 (37%) patients. Systemic glucocorticoids showed a survival benefit for SJS/TEN patients in all analyses compared with other forms of treatment. Cyclosporine treatment also showed promising results, despite being used in a small cohort of patients. No beneficial effects on mortality could be demonstrated for intravenous immunoglobulins. CONCLUSION: Glucocorticoids and cyclosporine may be tentatively recommended as the most promising immunomodulatory therapies for SJS/TEN, but these results should be investigated in future prospective controlled trials.

RESUMO

Thermal injuries have been a phenomenon intertwined with the human condition since the dawn of our species. Autologous skin translocation, also known as skin grafting, has played an important role in burn wound management and has a rich history of its own. In fact, some of the oldest known medical texts describe ancient methods of skin translocation. In this article, we examine how skin grafting has evolved from its origins of necessity in the ancient world to the well-calibrated tool utilized in modern medicine. The popularity of skin grafting has ebbed and flowed multiple times throughout history, often suppressed for cultural, religious, pseudo-scientific, or anecdotal reasons. It was not until the 1800s, that skin grafting was widely accepted as a safe and effective treatment for wound management, and shortly thereafter for burn injuries. In the nineteenth and twentieth centuries skin grafting advanced considerably, accelerated by exponential medical progress and the occurrence of man-made disasters and global warfare. The introduction of surgical instruments specifically designed for skin grafting gave surgeons more control over the depth and consistency of harvested tissues, vastly improving outcomes. The invention of powered surgical instruments, such as the electric dermatome, reduced technical barriers for many surgeons, allowing the practice of skin grafting to be extended ubiquitously from a small group of technically gifted reconstructive surgeons to nearly all interested sub-specialists. The subsequent development of biologic and synthetic skin substitutes have been spurred onward by the clinical challenges unique to burn care: recurrent graft failure, microbial wound colonization, and limited donor site availability. These improvements have laid the framework for more advanced forms of tissue engineering including micrografts, cultured skin grafts, aerosolized skin cell application, and stem-cell impregnated dermal matrices. In this article, we will explore the convoluted journey that modern skin grafting has taken and potential future directions the procedure may yet go.

RESUMO

Background and Objectives: Porcine xenografts have been used successfully in partial thickness burn treatment for many years. Their disappearance from the market led to the search for effective and efficient alternatives. In this article, we examine the synthetic epidermal skin substitute Suprathel® as a substitute in the treatment of partial thickness burns. Materials and Methods: A systematic review following the PRISMA guidelines has been performed. Sixteen Suprathel® and 12 porcine xenograft studies could be included. Advantages and disadvantages between the treatments and the studies' primary endpoints have been investigated qualitatively and quantitatively. Results: Although Suprathel had a nearly six times larger TBSA in their studies (p < 0.001), it showed a significantly lower necessity for skin grafts (p < 0.001), and we found a significantly lower infection rate (p < 0.001) than in Porcine Xenografts. Nonetheless, no significant differences in the healing time (p = 0.67) and the number of dressing changes until complete wound healing (p = 0.139) could be found. Both products reduced pain to various degrees with the impression of a better performance of Suprathel® on a qualitative level. Porcine xenograft was not recommended for donor sites or coverage of sheet-transplanted keratinocytes, while Suprathel® was used successfully in both indications. Conclusion: The investigated parameters indicate that Suprathel® to be an effective replacement for porcine xenografts with even lower subsequent treatment rates. Suprathel® appears to be usable in an extended range of indications compared to porcine xenograft. Data heterogeneity limited conclusions from the results.

RESUMO

Hair is a defining feature of mammals and has critical functions, including protection, production of sebum, apocrine sweat and pheromones, social and sexual interactions, thermoregulation, and provision of stem cells for skin homeostasis, regeneration, and repair. The hair follicle (HF) is considered a "mini-organ," consisting of intricate and well-organized structures which originate from HF stem and progenitor cells. Dermal papilla cells are the main components of the mesenchymal compartments in the hair bulb and are instrumental in generating signals to regulate the behavior of neighboring epithelial cells during the hair cycle. Mesenchymal-epithelial interactions within the dermal papilla niche drive HF embryonic development as well as the postnatal hair growth and regeneration cycle. This review summarizes the current understanding of HF development, repair, and regeneration, with special focus on cell signaling pathways governing these processes. In particular, we discuss emerging paradigms of molecular signaling governing the dermal papilla-epithelial cellular interactions during hair growth and maintenance and the recent progress made towards tissue engineering of human hair follicles.

RESUMO

OBJECTIVE: To review the effects of burn injury on nutritional requirements and how this can best be supported in a healthcare setting. METHOD: A literature search for articles discussing nutrition and/or metabolism following burn injury was carried out. PubMed, Embase and Web of Science databases were searched using the key search terms 'nutrition' OR 'metabolism' AND 'burn injury' OR 'burns'. There was no limitation on the year of publication. RESULTS: A total of nine articles met the inclusion criteria, the contents of which are discussed in this manuscript. CONCLUSION: Thermal injury elicits the greatest metabolic response, among all traumatic events, in critically ill patients. In order to ensure burn patients can meet the demands of their increased metabolic rate and energy expenditure, adequate nutritional support is essential. Burn injury results in a unique pathophysiology, involving alterations in endocrine, inflammatory, metabolic and immune pathways and nutritional support needed during the inpatient stay varies depending on burn severity and idiosyncratic patient physiologic parameters.

RESUMO

OBJECTIVE: Self-inflicted burns typically result in extensive injuries requiring intensive care and attention in a specialised burn unit. Burn units should be familiar with the optimal management of self-inflicted burns, including the psychological and psychiatric treatment. This paper describes the experiences of managing these challenging injuries in a German burn centre. METHODS: A retrospective review of patients with self-inflicted burns admitted to the burn centre between 2000 and 2017. Demographics, details of injury, presence of psychiatric disorder, clinical course, operative management and patient outcomes were recorded and compared with a control group without self-inflicted burns. Outcome measures included graft take rate, complications and need for further surgery. RESULTS: There were a total of 2055 burn patient admissions, with 17 cases (0.8%) of self-inflicted burns. The mean age was 36±11 years with an mean percentage total body surface area (%TBSA) burned of 43.5±22.5% which was not significantly different from the control group (p=0.184). Schizophrenia and personality disorder were the most common diagnoses in the self-inflicted burns patients (n=11; 65%). Of these, four had sustained previous self-inflicted burns. Length of hospital stay was significantly longer in the self-inflicted burn group than in the control group (49.0±16.7 days, respectively, p=0.002). CONCLUSION: Attempted suicide by self-inflicted burns represents <1% of burn admissions. This population demonstrates a high incidence of prior psychiatric disorders. Successful treatment includes multidisciplinary management of acute medical, surgical, and psychiatric care.

RESUMO

Burn wounds disrupt the body's primary defense against invasion and colonization by microorganisms. Topical antimicrobials are one component in burn wound care. These agents suppress microbial growth to advantage skin cells and wound healing. Topical antimicrobials can be divided into 2 superclasses: antiseptics and antibiotics. We review the 4 main classes of topical antiseptics (emulsifiers, acids, oxidizers, and heavy metals) and antiseptic-impregnated dressings in current clinical use and address the mechanisms, as well as the advantages and disadvantages of each antiseptic for burn wound management.

RESUMO

Improvements in acute burn care have enabled patients to survive massive burns that would have once been fatal. Now up to 70% of patients develop hypertrophic scars after burns. The functional and psychosocial sequelae remain a major rehabilitative challenge, decreasing quality of life and delaying reintegration into society. Approaches to optimise healing potential of burn wounds use targeted wound care and surgery to minimise the development of hypertrophic scarring. Such approaches often fail, and modulation of the established scar is continued although the optimal indication, timing, and combination of therapies have yet to be established. The need for novel treatments is paramount, and future efforts to improve outcomes and quality of life should include optimisation of wound healing to attenuate or prevent hypertrophic scarring, well-designed trials to confirm treatment efficacy, and further elucidation of molecular mechanisms to allow development of new preventive and therapeutic strategies.

RESUMO

Currently, there are various therapeutic approaches to reduce hypertrophic scarring; however, there is no standard evidence-based treatment protocol. Hence, a systematic review was performed to obtain a summary of the latest clinical trials to evaluate evidence for the treatment of hypertrophic scars. The review protocol was registered and approved by PROSPERO (CRD42015027040). PubMed and Web of Science were searched using predefined MeSH-Terms to identify studies published within the last 10 years regarding treatment for hypertrophic scars. Exclusion criteria included a level of evidence (LoE) lower than I, nonhuman in vivo studies, in vitro studies, studies on keloids, literature reviews, and non-English articles. The literature search identified 1,029 unique articles, whereas 6 articles were prospective, randomized, blinded, controlled clinical trials with a LoE I, and were thus included in the systematic analysis. Three clinical trials evaluated silicone products and pressure garments, and the other three studies investigated the efficacy of intralesional injections of triamcinolone (TAC), 5-Fluorouracil (5-FU) combined with TAC as well as the additional irradiation with a 585 nm pulsed-dye laser (PDL). Intralesional injections revealed significant improvements of the scar quality in terms of height, thickness, erythema, and pigmentation. Pressure garments showed favorable results but there was no evidence that silicone products were able to improve the scar quality. The systematic review demonstrated that there are just a few clinical trials with a LoE of I. Consequently, evidence is still lacking especially for noninvasive treatment regimens for hypertrophic scars. Intralesional injections of 5-FU mixed with a low dose of TAC can be seen as most appropriate treatment modality. Prospective clinical trials to determine the efficiency of silicone products are warranted.

RESUMO

BACKGROUND: Burn patients are prone to infections which often necessitate broad antibiotic coverage. Vancomycin is a common antibiotic after burn injury and is administered alone (V), or in combination with imipenem-cilastin (V/IC) or piperacillin-tazobactam (V/PT). Sparse reports indicate that the combination V/PT is associated with increased renal dysfunction. The purpose of this study was to evaluate the short-term impact of the three antibiotic administration types on renal dysfunction. METHODS: All pediatric and adult patients admitted to our centers between 2004 and 2016 with a burn injury were included in this retrospective review if they met the criteria of exposition to either V, V/IC, or V/PT for at least 48 h, had normal baseline creatinine, and no pre-existing renal dysfunction. Creatinine was monitored for 7 days after initial exposure; the absolute and relative increase was calculated, and patient renal outcomes were classified according to the Kidney Disease Improving Global Outcomes (KDIGO) criteria depending on creatinine increases and estimated creatinine clearance. Secondary endpoints (demographic and clinical data, incidences of septicemia, and renal replacement therapy) were analyzed. Antibiotic doses were modeled in logistic and linear multivariable regression models to predict categorical KDIGO events and relative creatinine increase. RESULTS: Out of 1449 patients who were screened, 718 met the inclusion criteria, 246 were adults, and 472 were children. Between the study cohorts V, V/IC, and V/PT, patient characteristics at admission were comparable. V/PT administration was associated with a statistically higher serum creatinine, and lower creatinine clearance compared to patients receiving V alone or V/IC in adults and children after burn injury. The incidence of KDIGO stages 1, 2, and 3 was higher after V/PT treatment. In children, the incidence of KDIGO stage 3 following administration of V/PT was greater than after V/IC. In adults, the incidence of renal replacement therapy was higher after V/PT compared with V or V/IC. Multivariate modeling demonstrated that V/PT is an independent predictor of renal dysfunction. CONCLUSION: Co-administration of vancomycin and piperacillin-tazobactam is associated with increased renal dysfunction in pediatric and adult burn patients when compared to vancomycin alone or vancomycin plus imipenem-cilastin. The mechanism of this increased nephrotoxicity remains elusive and warrants further scientific evaluation.

RESUMO

Partial-thickness burns involve damage to the upper layer of skin, which leaves nerve endings exposed, and therefore represent the most painful of several categories of thermal injuries. Historically, partial-thickness burns were treated conservatively by debriding the blisters, by daily tubbing and washing, and the application of new bandages with topical medications. Human amniotic membrane has been used for centuries as a biological wound dressing. In the past 20 years, there has been an increasing body of literature addressing the use of amniotic tissue in chronic wounds and burns. In this review, we present an overview of the use of amniotic membrane in the treatment of burns including processing methods and early clinical use. We believe that amniotic membranes have great potential in improving burn wound care in the future. Standardized processing methods and terminal sterilization ensure safety and allow the material to be available for use by health care providers around the world in clinical trials and for patient care.

RESUMO

OBJECTIVE: The aim of our Internet survey was to assess the preferences of burn specialists who use skin substitutes in patients with burns covering 20% or more of their total body surface area (TBSA). METHODS: An open, voluntary Internet-based cross-sectional survey was performed. Responses to 19 noncompulsory questions, and participant career and location information were collected. RESULTS: One hundred eleven specialists from 36 countries responded to our questionnaire. Sixty participants were located in Europe (54%), followed by 31 (28%) in North America, 15 (14%) in Asia, three (3%) in South America, one (1%) in Africa, and one (1%) in Australia. The importance of skin substitutes in medium-sized burns (covering 20%-60% TBSA) was rated as "essential" by 28% and "desirable" by 56% of the respondents. In severe burns >60% of TBSA, 81% of responders rated the use of skin substitutes as "essential" and 14% as "desirable". Skin substitutes were used in daily clinical practice by 96% of all participants. Biological and synthetic dressings were used by 53%. A majority (86%) think that biological dressings do not pose a risk to patients. Allografts represent the most frequently used wound coverage (51%), followed by xenografts (28%). All participants of the survey indicated that as of yet, there is no ideal skin substitute available. CONCLUSIONS: Split-thickness autografts still represent the most used wound cover for definitive treatment of severe burns. However, creation and implementation of an ideal skin substitute have yet to be achieved and therefore should be the focus of future work.

RESUMO

BACKGROUND: Several scar-scoring scales exist to clinically monitor burn scar development and maturation. Although scoring scars through direct clinical examination is ideal, scars must sometimes be scored from photographs. No scar scale currently exists for the latter purpose. MATERIALS AND METHODS: We modified a previously described scar scale (Yeong et al., J Burn Care Rehabil 1997) and tested the reliability of this new scale in assessing burn scars from photographs. The new scale consisted of three parameters as follows: scar height, surface appearance, and color mismatch. Each parameter was assigned a score of 1 (best) to 4 (worst), generating a total score of 3-12. Five physicians with burns training scored 120 representative photographs using the original and modified scales. Reliability was analyzed using coefficient of agreement, Cronbach alpha, intraclass correlation coefficient, variance, and coefficient of variance. Analysis of variance was performed using the Kruskal-Wallis test. Color mismatch and scar height scores were validated by analyzing actual height and color differences. RESULTS: The intraclass correlation coefficient, the coefficient of agreement, and Cronbach alpha were higher for the modified scale than those of the original scale. The original scale produced more variance than that in the modified scale. Subanalysis demonstrated that, for all categories, the modified scale had greater correlation and reliability than the original scale. The correlation between color mismatch scores and actual color differences was 0.84 and between scar height scores and actual height was 0.81. CONCLUSIONS: The modified scar scale is a simple, reliable, and useful scale for evaluating photographs of burn patients.

RESUMO

We have yet to create a human scar model that demonstrates the complex nature of hypertrophic scar and keloid formation as well as ways to prevent them despite emerging advances in our understanding of the immune system, the inflammatory response, and proteomic and genomic changes after injury. Despite more complex in vitro models, we fail to explain the fundamental principles to scar formation, and the timeline of their development. The solution to developing the ideal in vitro scar model is one that mimics the heterogeneous cellular and molecular interactions, as well as the evolving structure and function of human skin.

RESUMO

Exercise training for burn patients has become a major part of rehabilitation programs within the last decades. One of the main reasons for prolonged and long-term increased morbidity and mortality in this population is a persistent catabolic state with subsequent loss of lean body mass (LBM). A combination of resistance and aerobic exercises as well as stretching has shown to improve physical function by enhancing cardiopulmonary fitness, LBM, and strength and thus leading to ameliorated long-term outcomes of patients recovering from burns. In this literature review, we show an outline of the implementation of exercise training over the last decades into standardized care for patients with burns.

RESUMO

Global surgery describes a rapidly developing field that seeks to improve surgical treatment internationally, specifically in those specialized treatments that are not readily accessible, considered complex and expensive. Burns cause 300,000 deaths annually, 90% of which occur in low- and middle-income countries (LMICs). Burns are a public health problem since they can cause disability and death. Shriners Children's Texas is a unique model of global surgery for an important number of countries in Central and South Americas and Mexico, providing specialized acute burn care with low mortality for burned children. Survivors of severe burns may face devastating sequelae due to burn scar contractures and hypertrophic burn scars that may limit the social reintegration. Burn reconstruction is not easily accessible to patients in LMICs. After discharge from acute burn treatment at our hospital, patients may return every 6 months for in-person follow-up to assess any surgical, psychological, or rehabilitative needs. Telemedicine allows for monitoring of postoperative results and evaluation for new surgical procedures. Follow-up clinic visits called outreach clinics held in international hospitals or international Shriners Temples allow for evaluation of follow-up patients and new patients with reconstructive needs that may benefit from a treatment in Shriners Children's Texas in Galveston, Texas.
