- Electrical incidents are common and mostly uneventful, though can be severe and sometimes lethal. Aside from skin, muscle and soft tissue damage, electrical injuries can cause cardiac arrhythmias, the most common cardiac complication. The case of a 14-year-old girl who sustained 48.5% TBSA burns following a high-voltage electrical injury is described. She suffered five episodes of asystole 78 h following the injury, requiring extracorporeal membrane oxygenation. The cause of the delayed asystole was investigated and a PubMed literature search was conducted to explore late presenting cardiac sequelae following electrical injuries. This yielded fifteen studies, identified as relevant, of high quality and in the English language. These studies included a total of 1411 patients of whom only 3 were found to have had late potentially lethal arrhythmias, all manifesting within the first 24 h after the injury. Of these patients, 32 suffered cardiac arrests shortly after the electrical injury, 11 of which were documented as asystolic arrests though these were all from a single study with the rural locale and prolonged delay in arrival to the hospital setting contributing to this finding. To our knowledge, this is the only pediatric cardiac arrest developing in a stable patient over 72 h following the initial electrical injury. No other patient has suffered any significant cardiac complications first presenting outside the initial 24-h period following the electrical injury. Guidelines and recommendations on post electrical injury observation of patient vary and further research into this field is required to allow for guidance unification.

- SUMMARYDelayed complications of electrical burns are mostly unexpected, and the link between the injury and the symptoms oftengoes unrecognized. A possible relation between source-ground sites and late clinical manifestations was recently emphasized. We report aunique case of combined intestinal-spinal delayed complications following a high-voltage electrical injury, a possible explanation being agreater current flow through the right hemisoma. The potential for late complications is an additional feature that physicians must considerin managing electrical injuries. Manifestations are variable and presentation is confounding, but current flow path can constitute a precioussource of information to predict complications in the late phase of management.

Altered adrenal and gonadal steroids biosynthesis in patients with burn injury
- 2016
-
Ingår i: Clinical Mass Spectrometry. - : Elsevier BV. - 2213-8005 .- 2376-9998. ; 1, s. 19-26

- Introduction: Burn injury inevitably leads to changes in the endogenous production of cytokines, as well as adrenal and gonadal steroids. Previous studies have reported gender-related differences in outcome following burn injury, which suggests that gonadal steroids may play a role. The aim of this study was to assess alterations in concentration of endogenous steroids in patients with burn injury.Methods: For this single-center, prospective descriptive study, high-sensitivity liquid chromatography tandem mass spectrometry (LC-MS/MS)-based steroid quantification was used to determine longitudinal profiles of the concentrations of endogenous steroids in plasma from sixteen adult male patients with burn injury (14.5-72% of total body surface area). Steroids were extracted from plasma samples and analyzed using multiple reaction monitoring acquisition, with electrospray ionization on a triple quadruple mass spectrometer. Total protein concentration was measured in the samples using spectrophotometry.Results: Steroid and total protein concentration distributions were compared to reference intervals characteristic of healthy adult men. Concentrations of the following steroids in plasma of burn injured patients were found to correlate positively to the area of the burn injury: cortisol (r = 0.84), corticosterone (r = 0.73), 11-deoxycortisol (r = 0.72), androstenedione (r = 0.72), 17OH-progesterone (r = 0.68), 17OH-pregnenolone (r = 0.64) and pregnenolone (r = 0.77). Concentrations of testosterone decreased during the acute phase and were up to ten-times lower than reference values for healthy adult men, while concentrations of estrone were elevated. By day 21 after injury, testosterone concentrations were increased in younger, but not older, patients. The highest concentrations of estrone were observed on day 3 after the injury and then declined by day 21 to concentrations comparable to those observed on the day of the injury.Conclusion: Burn injury alters endogenous steroid biosynthesis, with decreased testosterone concentrations and elevated estrone concentrations, during the first 21 days after the injury. Concentrations of glucocorticoids, progestagens and androgen precursors correlated positively with the area of burn injury. The finding of increased estrone following burn injury needs to be confirmed in a larger hypothesis driven study.

Tidskriftsartikel (refereegranskat)abstract
- Burn injury causes major inflammatory activation and cytokine release, however, the temporal resolution of the acute and sub-acute inflammatory response has not yet been fully delineated. To this end, we have quantified 20 inflammatory mediators in plasma from 44 adult patients 0-21 days after burn injury and related the time course of these mediators to % total body surface area (TBSA) burned, clinical parameters, organ failure and outcome. Of the cytokines analyzed in these patients, interleukin 6 (IL-6), IL-8, IL-10 and monocyte chemoattractant protein 1 (MCP-1) correlated to the size of the injury at 24-48h after burn injury. In our study, the concentration of IL-10 had prognostic value in patients with burn injury both measured at admission and at 24-48h after injury. However, simple demographic data such as age, % burned TBSA, inhalation injury and their combination, the Baux score and modified Baux score, outperform most of the cytokines, with the exception of IL-8 and MCP1 levels on admission, in predicting death.

Development and evaluation of deep learning algorithms for assessment of acute burns and the need for surgery
- 2023
-
Ingår i: Scientific Reports. - : Springer Nature. - 2045-2322. ; 13:1
-
Tidskriftsartikel (refereegranskat)abstract
- Assessment of burn extent and depth are critical and require very specialized diagnosis. Automated image-based algorithms could assist in performing wound detection and classification. We aimed to develop two deep-learning algorithms that respectively identify burns, and classify whether they require surgery. An additional aim assessed the performances in different Fitzpatrick skin types. Annotated burn (n = 1105) and background (n = 536) images were collected. Using a commercially available platform for deep learning algorithms, two models were trained and validated on 70% of the images and tested on the remaining 30%. Accuracy was measured for each image using the percentage of wound area correctly identified and F1 scores for the wound identifier; and area under the receiver operating characteristic (AUC) curve, sensitivity, and specificity for the wound classifier. The wound identifier algorithm detected an average of 87.2% of the wound areas accurately in the test set. For the wound classifier algorithm, the AUC was 0.885. The wound identifier algorithm was more accurate in patients with darker skin types; the wound classifier was more accurate in patients with lighter skin types. To conclude, image-based algorithms can support the assessment of acute burns with relatively good accuracy although larger and different datasets are needed.

Documented nutritional therapy in relation to nutritional guidelines post burn injury : a retrospective observational study
- 2023
-
Ingår i: Clinical Nutrition ESPEN. - : Elsevier. - 2405-4577. ; 56, s. 222-229
-
Tidskriftsartikel (refereegranskat)abstract
- Background & aims: Intensive nutritional therapy is an essential component of burn care. Regardingpost-minor burn injuries, the literature is lacking. The aim of this study was to evaluate documentednutritional therapy in relation to international guidelines after both minor and major burn injuries. The secondary aim of this study was to evaluate the adequacy of energy and protein intake compared toindividual nutritional goals post-burn injury.Methods: A retrospective observational single-centre study including patients admitted between 2017and 2019 at a burn centre in Sweden was performed. The patients included in the study were >18 years old and in need of hospital care for > 72 h post-burn injury. Information about patients' demographics,nutritional therapy, and clinical characteristics of burn injury was collected. The patients were dividedaccording to total body surface area burnt (TBSA %) into minor burn injuries (TBSA <20%) and major burninjuries (TBSA >20%). Descriptive statistics were used to analyse data. Adherence to guidelines wasestablished by comparing 24 nutritional therapy recommendations to documented treatment. If documented nutritional treatment were in accordance with guidelines, adherence was considered high(>80%), moderate (60-79.9%) or low (<59.9%).Results: One hundred thirty-four patients were included, 90 patients with minor burn injuries and 44patients with major burn injuries. Documented adherence to the nutritional guideline was overall low.After minor burn injury, 8% (2/24) of nutritional therapy recommendations had a high adherence (fatintake <35% of total energy intake and enteral nutrition as prioritized feeding route), 17% (4/24) amoderate adherence, and 75% (18/24) a low adherence. In patients treated after a major burn injury,there were two recommendations with documented high adherence (Vitamin C and Zinc); 25% (6/24)had moderate adherence, and 67% (16/24) had low adherence. In addition, quite a large amount ofmissing data was found.Adequacy of documented nutritional intake, compared to the individual documented goal, was 78%(±23%) for energy and 66% (±22%) for protein after minor burn injury. After major burn injury, the adequacy was 89% (±21%) for energy and 78% (±19%) for protein, respectively.Conclusions: This study revealed low adherence to nutritional guidelines in patients treated for minorand major burn injuries. Compared to major burn injuries, lower documented adequacy for both energyand proteins was found in minor burn injuries. Given the disparity between guidelines and documentednutritional therapy, and the lack of specific guidelines for minor burn injuries, there could be aconsiderable risk of inadequate nutritional therapy post-burn injury.

Two Modified Questionnaires for the Assessment of Nutrition Impact Symptoms in the Rehabilitation Phase after Burn Injury : A Content Validation Study
- 2022
-
Ingår i: European Burn Journal. - : MDPI. - 2673-1991. ; 3:1, s. 156-164
-
Tidskriftsartikel (refereegranskat)abstract
- Disease Related Appetite Questionnaire (DRAQ) and Eating Symptom Questionnaire(ESQ) are used to assess nutrition impact symptoms, which are symptoms that can negatively affectthe patients’ food intake. However, these questionnaires have not yet been adapted to the needsof patients recovering from burn injuries. Our aim was therefore to develop DRAQ and ESQ forassessments of nutrition impact symptoms after burn injury. A content validation index (I-CVI) foritems included in DRAQ and ESQ, regarding their relevance for possible nutrition impact symptomsin a burn-injured patient (Likert scale 1–4), was performed by an expert review group. A clarityvalidation by expert and non-expert reviewers was carried out. Two of the eleven questions inDRAQ and eight of the fourteen questions in ESQ were not considered relevant and were thereforeremoved from the questionnaires. Five additional questions were added to DRAQ and two to ESQ.A high degree of consensus on relevance (scale-content validity index average, S-CVI/Ave, 0.86 forDRAQ-burn and 0.83 for ESQ-burn) was reached in the expert group. To conclude, it is suggestedthat we use developed forms of DRAQ and ESQ (DRAQ-burn and ESQ-burn) for the assessment ofnutrition impact symptoms, specifically during the rehabilitation phase of burn-injured patients.

Fatigue after burn – Is it common? A preliminary survey
- 2021
-
Ingår i: Burns Open. - : Elsevier. - 2468-9122. ; 5:3, s. 134-136
-
Tidskriftsartikel (refereegranskat)abstract
- Physical function and daily activities are often affected after burn injury. Fatigue is a condition that is rarely assessed. Being a well-known sequela after traumatic brain-injury or diseases of the nervous system, fatigue has also been described among the burn population with a negative impact on daily activities and reduced capacity for work.The aim of this study was to examine if, and to what extent, fatigue is a problem among our burn victims.Twenty consecutive patients scheduled for follow-up at the Burn center’s outpatient clinic in Uppsala, were asked to fill out the Fatigue Severity Scale (FSS). A healthy reference group without a burn injury, gender and age matched, were asked to fill out the same questionnaire.The results show that the patient group has a statistically significant higher score of fatigue compared to the reference group (p = 0.004). However, the results must be interpreted with caution considering the relatively small sample size. In future research it is also important to investigate the relationship between fatigue and daily activities, depression, return to work, and quality of life.

-
Tidskriftsartikel (refereegranskat)abstract
- A burn injury affects a person’s health-related quality of life (HRQoL) in different ways and might influence their daily life for months and years afterward. The aim of this study was to examine how activity performance and subjective scar estimation relate to self-rated health and whether this changes in the first year post-burn. Fifty consecutive patients who were scheduled for follow-up at the Burn Center’s outpatient clinic in Uppsala were included. Assessments of HRQoL (EQ-5D), activity performance (DASH), and subjective scar evaluation (POSAS) were conducted at 6 and 12 months post-burn. The results show a statistically significant correlation between self-rated HRQoL and activity performance (p = 0.001) and between self-rated HRQoL and subjective scar estimation (p = 0.000) at 6 but not at 12 months post-burn. A possible explanation of the lack of correlation at one year post-burn might be the patient´s expectations of his or her recovery. In future research, it would be interesting to investigate the long-term correlations between quality of life and activity performance.

Tidskriftsartikel (refereegranskat)abstract
- IntroductionBurn injuries are a common traumatic injury. Large burns have high mortality requiring intensive care and accurate mortality predictions. To assess if machine learning (ML) could improve predictions, ML algorithms were tested and compared with the original and revised Baux score.MethodsAdmission data and mortality outcomes were collected from patients at Uppsala University Hospital Burn Centre from 2002 to 2019. Prognostic variables were selected, ML algorithms trained and predictions assessed by analysis of the area under the receiver operating characteristic curve (AUC). Comparison was made with Baux scores using DeLong test.ResultsA total of 17 prognostic variables were selected from 92 patients. AUCs in leave-one-out cross-validation for a decision tree model, an extreme boosting model, a random forest model, a support-vector machine (SVM) model and a generalised linear regression model (GLM) were 0.83 (95% confidence interval [CI] = 0.72–0.94), 0.92 (95% CI = 0.84–1), 0.92 (95% CI = 0.84–1), 0.92 (95% CI = 0.84–1) and 0.84 (95% CI = 0.74–0.94), respectively. AUCs for the Baux score and revised Baux score were 0.85 (95% CI = 0.75–0.95) and 0.84 (95% CI = 0.74–0.94). No significant differences were observed when comparing ML algorithms with Baux score and revised Baux score. Secondary variable selection was made to analyse model performance.ConclusionThis proof-of-concept study showed initial credibility in using ML algorithms to predict mortality in burn patients. The sample size was small and future studies are needed with larger sample sizes, further variable selections and prospective testing of the algorithms.

Evaluating topical opioid gel on donor site pain : A small randomised double blind controlled trial
- 2016
-
Ingår i: International Journal of Surgery Open. - : Elsevier BV. - 2405-8572. ; 4, s. 5-9
-
Tidskriftsartikel (refereegranskat)abstract
- BackgroundAutologous donor skin harvested for transplantation is a common procedure in patients with burns, and patients often feel more pain at the donor site than is justified by the extent of trauma. Topical morphine gels have been thought to have an effect on peripheral opioid receptors by creating antinociceptive and anti-inflammatory effects, which could potentially reduce the systemic use of morphine-like substances and their adverse effects.MethodsWe therefore did a paired, randomised, double-blind placebo study to investigate the effect of morphine gel and placebo on dual donor sites that had been harvested in 13 patients. Pain was measured on a visual analogue scale (VAS) 15 times in a total of 5 days.ResultsThe mean (SD) VAS was 1.6 (2.3) for all sites, 1.5 (2.2) for morphine, and 2.0 (2.5) for placebo. The pain relieving effects of morphine gel were not significantly better than placebo.ConclusionThe assessment of pain at donor sites is subjective, and more systematic and objective studies are needed.

Accumulation of Silver and Delayed Re-epithelialization in Normal Human Skin : An ex-vivo Study of Different Silver Dressings.
- 2009
-
Ingår i: Wounds (King of Prussia, Pa.). - 1044-7946 .- 1943-2704. ; 21:5
-
Tidskriftsartikel (refereegranskat)abstract
- Silver is commonly used in wound dressings and topical formulations to assist in the management of wounds that are infected or at risk of becoming infected. They provide potent broad-spectrum antimicrobial activity, but should not cause sustained staining of the skin, dermal or systemic accumulation of silver, or discomfort to the patient. However, clinicians and healthcare personnel have been concerned about topical staining of the skin and complaints of additional pain from patients treated with certain silver dressings. Some delay in re-epithelialization has also been noticed and reported. The reasons for this are not clear, and the authors believed further study regarding the possible effects of silver accumulation and silver dressings' effect on re-epithelialization was required. The authors studied possible silver accumulation and re-epithelialization in normal human dermal skin. The results showed that most of the dressings or treatments discolored the wound surface and that there was a dermal accumulation of what were assumed to be silver particles. Varying grades of accumulation were found in deep dermal tissue, particularly around blood vessels, depending on the dressing used. The results also indicated that all of the tested products delayed re-epithelialization in this model. .

Tidskriftsartikel (refereegranskat)abstract
- Spider silk is an interesting biomaterial for medical applications. Recently, a method for production of recombinant spider silk protein (4RepCT) that forms macroscopic fibres in physiological solution was developed. Herein, 4RepCT and MersilkTM (control) fibres were implanted subcutaneously in rats for seven days, without any negative systemic or local reactions. The tissue response, characterised by infiltration of macrophages and multinucleated cells, was similar with both fibres, while only the 4RepCT-fibres supported ingrowth of fibroblasts and newly formed capillaries. This in vivo study indicates that 4RepCT-fibres are well tolerated and could be used for medical applications, e.g., tissue engineering.

- Background: Safe and effective methods for sedation and analgesia in pediatric burn patients are strongly warranted. This retrospective study of electronic health care records aims to evaluate the safety and efficacy of intranasal dexmedetomidine combined with rectal ketamine as procedural sedation for young children undergoing dressing changes and debridement of burn wounds.Methods: Documentation was analyzed from 90 procedures in 58 pediatric patients aged <5 years. Safety and efficacy of the method were assessed based on documentation for complications, adverse effects, pain level, level of sedation and preoperative and recovery time.Results: All 90 sedations were completed without significant adverse events with acute airway management or medical intervention. The combination of dexmedetomidine-ketamine produced acceptable analgesia during the procedure and effectively relieved postoperative pain. However, the approach was insufficient for 7/58 patients (7.8%); these patients were converted from the dexmedetomidine-ketamine combination to intravenous anesthesia. In 23% of the cases an extra dose of either ketamine of dexmedetomidine was administered. Moreover, there were two cases of delayed awakening with recovery time >120 min.Conclusion: The drug combination intranasal dexmedetomidine and rectal ketamine is a safe and reliable approach for procedural sedation and analgesia in pediatric patients undergoing burn wound procedures, producing a clinically stable sedative condition requiring only basic monitoring.

- Objective: Acceleration of wound healing promises advantages for patients and caregivers in reducing the burden of disease, avoiding complications such as wound infections, and improving the long-term outcome. However, medicines that can accelerate wound healing are lacking. The objective of this open, blindly evaluated, randomized, multicenter phase III study was to compare intra-individually the efficacy and tolerability of Oleogel-S10 with fatty gauze dressing versus Octenilin (R) wound gel with fatty gauze dressing in accelerating the healing of superficial partial thickness burn wounds. Methods: Acute superficial partial thickness burn wounds in adults caused by fire, heat burn or scalding were divided into 2 halves and randomly assigned to treatment with Oleogel-S10 or Octenilin (R) wound gel. Photos for observer-blinded analysis of wound healing were taken at each wound dressing change. Percentages of reepithelialization were assessed at defined intervals. Efficacy and tolerability were evaluated based on a 5-point Likert scale. Results: Of 61 patients that were enrolled, 57 received the allocated intervention and 48 completed treatment. The percentage of patients with earlier wound healing was significantly higher for Oleogel-S10 (85.7%, n=30) compared to Octenilin (R) wound gel (14.3%, n= 5, p <0.0001). The mean intra-individual difference in time to wound closure was -1.0 day in favour of Oleogel-S10 (-1.4, -0.6; 95% CI, p <0.0001). Most investigators (87.0%) and patients (84.8%) evaluated the efficacy of Oleogel-S10 to be 'better' or 'much better' than that of Octenilin (R) wound gel. Long-term outcome 3 months and 12 months post injury was improved in some patients. Conclusions: Oleogel-S10 (Episalvan) significantly accelerated the healing of superficial partial thickness burn wounds. It was safe and well tolerated. (C) 2018 Elsevier Ltd and ISBI.

- Sex steroid exposure constitutes a risk factor for breast cancer, but little is known about the effects of sex steroids on the normal breast, largely because of the lack of convenient models. We have developed a method of culturing normal breast tissue ex vivo. We have applied this method to investigate the effects of estradiol and progesterone on the key angiogenic mediator, vascular endothelial growth factor (VEGF), in the breast. Whole breast tissue was obtained from routine reduction mammoplasty. Tissue biopsies were cultured in vitro for 1-3 weeks, and the expression of luminal cytokeratin 18 was determined by immunohistochemistry. As an application, tissue biopsies were treated in vitro for 1 week with or without estradiol or estradiol and progesterone. Estrogen receptor, progesterone receptor, and Ki-67 were analyzed, and VEGF levels were examined by quantitative immunoassay and immunohistochemistry. Whole breast tissue was cultured ex vivo for 1 week with preserved morphology. Increased detachment of the luminal epithelium was observed after 2 weeks. Estradiol increased extracellular levels of VEGF in normal breast tissue biopsy medium. The addition of progesterone had neither stimulatory nor inhibitory effects on secreted VEGF. The method of whole breast tissue culturing thus provide a means by which to explore the biology of normal breast tissue. Our results suggest that estradiol exerts pro-angiogenic effects in normal breast by increasing levels of biologically active VEGF.

Tidskriftsartikel (refereegranskat)abstract
- Background: It is unknown whether lung-protective ventilation is applied in burn patients and whether they benefit from it. This study aimed to determine ventilation practices in burn intensive care units (ICUs) and investigate the association between lung-protective ventilation and the number of ventilator-free days and alive at day 28 (VFD-28). Methods: This is an international prospective observational cohort study including adult burn patients requiring mechanical ventilation. Low tidal volume (V-T) was defined as V-T <= 8 mL/kg predicted body weight (PBW). Levels of positive end-expiratory pressure (PEEP) and maximum airway pressures were collected. The association between V-T and VFD-28 was analyzed using a competing risk model. Ventilation settings were presented for all patients, focusing on the first day of ventilation. We also compared ventilation settings between patients with and without inhalation trauma. Results: A total of 160 patients from 28 ICUs in 16 countries were included. Low V-T was used in 74% of patients, median V-T size was 7.3 [interquartile range (IQR) 6.2-8.3] mL/kg PBW and did not differ between patients with and without inhalation trauma (p= 0.58). Median VFD-28 was 17 (IQR 0-26), without a difference between ventilation with low or high V-T (p= 0.98). All patients were ventilated with PEEP levels >= 5 cmH(2)O; 80% of patients had maximum airway pressures <30 cmH(2)O. Conclusion: In this international cohort study we found that lung-protective ventilation is used in the majority of burn patients, irrespective of the presence of inhalation trauma. Use of low V-T was not associated with a reduction in VFD-28.

- Introduction: The Surviving Sepsis Campaign was developed to improve outcomes for all patients with sepsis. Despite sepsis being the primary cause of death after thermal injury, burns have always been excluded from the Surviving Sepsis efforts. To improve sepsis outcomes in burn patients, an international group of burn experts developed the Surviving Sepsis After Burn Campaign (SSABC) as a testable guideline to improve burn sepsis outcomes. Methods: The International Society for Burn Injuries (ISBI) reached out to regional or na-tional burn organizations to recommend members to participate in the program. Two members of the ISBI developed specific "patient/population, intervention, comparison and out-come" (PICO) questions that paralleled the 2021 Surviving Sepsis Campaign [1]. SSABC parti-cipants were asked to search the current literature and rate its quality for each topic. At the Congress of the ISBI, in Guadalajara, Mexico, August 28, 2022, a majority of the participants met to create "statements" based on the literature. The "summary statements" were then sent to all members for comment with the hope of developing an 80% consensus. After four reviews, a consensus statement for each topic was created or "no consensus" was reported. Results: The committee developed sixty statements within fourteen topics that provide guidance for the early treatment of sepsis in burn patients. These statements should be used to improve the care of sepsis in burn patients. The statements should not be considered as "static" comments but should rather be used as guidelines for future testing of the best treatments for in burn should be on a basis. Conclusion: Members of the burn community from the around the world have developed the Surviving Sepsis After Burn Campaign guidelines with the goal of improving the outcome of sepsis in burn patients.

- Providing cutaneous wounds with sufficient epidermis to prevent infections and fluid loss is one of the most challenging tasks associated with surgical treatment of burns. Recently, application of cultured keratinocytes in this context has allowed this challenge to be met without several of the limitations connected with the use of split-thickness skin grafts. The continuous development of this novel approach has now revealed that transplantation of cultured autologous keratinocytes as single-cell suspensions exhibits several advantages over the use of cultured epidermal grafts. However, a number of methodological problems remain to be solved, primarily with regards to the complexity of culturing these cells; loss of viability and other negative effects during their preparation and transportation; the relatively long period of time required following transplantation to obtain a sufficiently protective epidermis. In the present investigation we attempted to eliminate these limitations by culturing the keratinocytes on macroporous gelatin spheres. Accordingly, the efficacies of normal human keratinocytes in single-cell suspension or growing on macroporous gelatin spheres, as well as of split-thickness skin grafts in healing wounds on athymic rats were compared. Human keratinocytes were found to adhere and proliferate efficiently both on the surface and within the pores of such spheres. Transplantation of such cells adherent to the spheres resulted in significantly more rapid formation of a stratified epidermis than did transplantation of single-cell suspensions or spheres alone. Twenty-three days after transplantation, the epidermis formed from the cells bound to the spheres was not as thick as the epidermis on wounds covered with split-thickness skin grafts, but significantly thicker than on wounds to which single-cell suspensions, spheres alone or no transplant at all was applied. Furthermore, fluorescence in situ hybridisation revealed that the transplanted keratinocytes, both those adherent to gelatin spheres and those in single-cell suspension, were components of the newly formed epidermis. These findings indicate that application of biodegradable macroporous spheres may prove to be of considerable value in designing cell-based therapies for the treatment of acute and persistent wounds.

- BACKGROUNDGlutamine is thought to have beneficial effects on the metabolic and stress response to severe injury. Clinical trials involving patients with burns and other critically ill patients have shown conflicting results regarding the benefits and risks of glutamine supplementation.METHODSIn a double-blind, randomized, placebo-controlled trial, we assigned patients with deep second-or third-degree burns (affecting >= 10% to >= 20% of total body-surface area, depending on age) within 72 hours after hospital admission to receive 0.5 g per kilogram of body weight per day of enterally delivered glutamine or placebo. Trial agents were given every 4 hours through a feeding tube or three or four times a day by mouth until 7 days after the last skin grafting procedure, discharge from the acute care unit, or 3 months after admission, whichever came first. The primary outcome was the time to discharge alive from the hospital, with data censored at 90 days. We calculated subdistribution hazard ratios for discharge alive, which took into account death as a competing risk.RESULTS A total of 1209 patients with severe burns (mean burn size, 33% of total body-surface area) underwent randomization, and 1200 were included in the analysis (596 patients in the glutamine group and 604 in the placebo group). The median time to discharge alive from the hospital was 40 days (interquartile range, 24 to 87) in the glutamine group and 38 days (interquartile range, 22 to 75) in the placebo group (subdistribution hazard ratio for discharge alive, 0.91; 95% confidence interval [CI], 0.80 to 1.04; P = 0.17). Mortality at 6 months was 17.2% in the glutamine group and 16.2% in the placebo group (hazard ratio for death, 1.06; 95% CI, 0.80 to 1.41). No substantial between-group differences in serious adverse events were observed.CONCLUSIONSIn patients with severe burns, supplemental glutamine did not reduce the time to discharge alive from the hospital.

- Scald is one type of burn that s often mentioned alone and occurs mostly in the paediatric population. Inhaled steam is mostly cooled off in the airways, why thermal damage is rarely seen. A sudden exposure to hot steam/inhalation can cause a thermal inhalation injury. A scoping review was performed, with the aim to summarize all published papers in English, about steam-related injuries. The search was conducted using the PubMed (R) and Cochrane libraries on 19th of May 2021, without a set time period. Out of a total of 1186 identified records, 31 were chosen for review. Burns related to the contact with steam are generally rare and can be both minor and severe. The more severe cases related to steam exposure are mostly workplace accidents and the minor injuries reported in the literature are often related to steam inhalation therapy, especially in the paediatric population. This review describes the challenges that can be found dealing with patients suffering from cutaneous steam burns and/or steam inhalation injuries. A steam injury to the airways or the skin can be directly life-threatening and should be treated with caution. This type of injury can lead to acute respiratory insufficiency and sometimes death. A case of a male patient with extensive cutaneous steam burns and a steam inhalation injury who passed away after 11 days of treatment is also presented to illustrate this review. Level of evidence: Level V, Therapeutic; Risk/Prognostic Study.

Tidskriftsartikel (refereegranskat)abstract
- Introduction: Estimation of total body surface area (TBSA) burnt and burn depth are among the most central parts of acute burn assessment/treatment as they determine the level and type of care needed. Traditional methods for determining burn extent on admission often lead to inaccurate estimations, especially in paediatric or overweight patients.Aim: To compare %TBSA at admission with validated %TBSA at discharge in different patient populations to investigate if significant over- or underestimation occurs.Method: This retrospective observational study is based on a patient registry of all the patients (n = 863) treated at the Uppsala University Hospital's Burn Centre between 2010 and 2018. The patients were divided into subgroups based on age, gender, body mass index (BMI) and validated burn extent. The %TBSA estimated at admission was compared to the validated %TBSA in all groups separately.Results: As has been published before, we also found that the %TBSA in paediatric patients was more often overestimated as were the smaller injuries, whereas larger injuries were often underestimated. BMI did not clearly affect the estimations and there was no clear difference between the genders in estimated %TBSA.Conclusion: Inaccurate estimations of %TBSA are common, particularly for paediatric patients and small or large injuries. We recommend a careful accurate approach when calculating %TBSA in the paediatric population to avoid over- and under-resuscitation. Increased education and training are recommended to improve accurate estimation in the future.Lay Summary: The correct estimation of both extent and depth of burn is very important. This assessment guides the lever of care needed, the necessary amount of fluid resuscitation, the predicted outcome and more. It has been proven notably difficult to correct assess, especially the extent of a burn. Despite different tools as the "Rule of Nine" (body area divided into multiples of 9% body surfaces), the "Rule of Palm" (Patient's palm, fingers included, approximates 1% of body surfaces), the Lund & Browder chart (detailed, age-specific body areas) and different more technical solutions. Often inaccurate estimations are done which thus affect the treatment. This depth and extent estimation is usually performed when the patient is admitted. However, it is known that burns change appearance during the first few days of care. In our Burn Center we have also performed this estimation when the patient is discharged. At this point it is known the true extent and depth of the initial burn. In this retrospective observational study, we compared the burn extent estimated on admission with the one on discharge to investigate whether the initial assessment is accurate. This study highlights the issue of frequent inaccurate burn extent estimations, especially in subgroups as overweight patient or pediatric patients.

Purpura fulminans, TEN, and disseminated herpes simplex : An unexpected combination
- 2022

Tidskriftsartikel (refereegranskat)abstract
- Stevens-Johnson syndrome (SJS), toxic epidermal necrolysis (TEN), and purpura fulminans (PF) are all rare conditions. A combination of these 3 conditions together with a viral infection is very rare. A 52-year-old, previously healthy woman which developed SJS, potentially due to a reaction to CT contrast, although this is still unknown. This developed into TEN on day 10 of the initial admission, the patient scored 3 points on SCORTEN. On day 12 from initial admission, she developed unexpected multiorgan failure and PF. The patient passed away 2 days later, the autopsy demonstrates herpes simplex virus in the bladder and lungs on immunohistological staining. Our clinical case encountered the challenge of differentiating TEN and PF. The microscopic and immunochemical examination confirmed the clinical suspicion of PF but also a disseminated herpes simplex infection. We speculate the clinical route of this case started SJS and TEN, leading to superimposed infection with three different types of bacteria, confirmed in blood cultures, and a disseminated viral infection. The combination of all these diagnoses are very rare, no similar case has been described in adults to the authors' knowledge. We recommend a prompt diagnosis and early recognition of both bacterial and viral infections to prevent the development of PF.

Sociodemographic Patterns of Pediatric Patients in Specialized Burn Care in Sweden
- 2022
-
Ingår i: Plastic and Reconstructive Surgery - Global Open. - : Ovid Technologies (Wolters Kluwer Health). - 2169-7574. ; 10:4

Tidskriftsartikel (refereegranskat)abstract
- Background: Trauma is a leading cause of mortality in children. Burns affect children disproportionally. Although burn incidence and mortality are decreasing, differences in the risk depend on socioeconomic status. The present study aimed to investigate the sociodemographic patterns of pediatric patients (0-17 years) managed at the two burn centers in Sweden. Uppsala, and Linkoping, between 2010 and 2020.Method: This retrospective register-based study used hospital records from the two burn centers combined with information front Statistics Sweden plus data regarding number of asylum seekers from the Swedish Migrations Agency. Choropleth maps representing the patients' geographical distribution were created. Information about income levels per geographic area was added. A Wilcoxon signed-rank test was performed to investigate differences in median income levels between the areas where the patients lived, related to Sweden's median income.Results: The study included 2455 patients. Most of the children aged below 5 years (76%) and were boys (60%). The mean percentage of total skin area was 4.2%. There was no significant increment or decrease in the incidence of pediatric burns during the study. Most patients with recorded zip codes lived in areas with an income level below the national median (n = 1974, 83%). Children with asylum status were over-represented compared with residents and/or Swedish citizens.Conclusions: In Sweden, most pediatric burns occur in families that live in areas with low-income levels. Pediatric burns affect children with asylum status disproportionally compared with those who are residents in and/or citizens of Sweden. Prevention strategies should be designed and implemented to alleviate this health inequity.

- Continuous improvement in burn trauma care has led to decreasing mortality, morbidity, and length of hospital stay. Current data from the Swedish population is lacking, which was the reason for this investigation. Data was gathered from the Swedish database for medical care (based on ICD-9). All Swedish care providers are enrolled and assumed to report data. Hence, the quality of the database is considered reasonably good, although data from individual patients may be incorrectly recorded due to clerical errors. Available data indicate that the number of burn victims seeking medical care has decreased by 16% during the past decade, whereas mortality has decreased by 70%! The demographic data is otherwise similar to what has previously been reported in the international literature.

- In Sweden, approximately 6% of all human transportation is made via buses. The Swedish Board of Accident Investigation and the Swedish Rescue Services Agency have pointed out repeatedly that buses are potential fire and burn hazards, not only when involved in collisions but also in other circumstances. The number of fire incidents is increasing, especially in newer buses. In conjunction with the Swedish Rescue Services Agency, we examined some of the recent bus fires in Sweden. We did not find any casualties, but the results of our study suggest that casualties as a result of bus fires are imminent unless preventive measures are taken. We also studied experiences from previous bus fires and suggest preventive measures.

- Full thickness skin wounds in humans heal with scars, but without regeneration of the dermis. A degradable poly(urethane urea) scaffold (PUUR), Artelon® is already used to reinforce soft tissues in orthopaedics, and for treatment of osteoarthritis of the hand, wrist and foot. In this paper we have done in vitro experiments followed by in vivo studies to find out whether the PUUR is biocompatible and usable as a template for dermal regeneration. Human dermal fibroblasts were cultured on discs of PUUR, with different macrostructures (fibrous and porous). They adhered to and migrated into the scaffolds, and produced collagen. The porous scaffold was judged more suitable for clinical applications and 4 mm Ø, 2 mm-thick discs of porous scaffold (12% w/w or 9% w/w polymer solution) were inserted intradermally in four healthy human volunteers. The implants were well tolerated and increasing ingrowth of fibroblasts was seen over time in all subjects. The fibroblasts stained immunohistochemically for procollagen and von Willebrand factor, indicating neocollagenesis and angiogenesis within the scaffolds. The PUUR scaffold may be a suitable material to use as a template for dermal regeneration. ©2008 Landes Bioscience.
