Is the pre-operative wound culture necessary before skin grafting minor burns? A pilot study in a low resource setting burn service.

The most common cited cause of split-thickness skin graft failure is infection and due to the association between bacterial findings in wound beds an attempt to decrease the bacterial burden before skin-grafting evolved. Thus, pre-operative microbiology swabs of the wound bed became routine at some institutions prior to grafting. This is not standard practice in the Pietermaritzburg burn service. Emphasis is instead placed on a strict protocol of intra-operative wound bed preparation to promote adequate graft take. This pilot study aims to evaluate whether pre-operative wound swabs are appropriate. We performed a prospective observational study to determine if positive wound cultures were associated with graft failure. All patients with a burn surface area of less than 10 %, where delayed grafting (later than 28 days from time of burn injury) was performed, from March to December 2021 were analyzed. Patient demographics, days from burn to graft, %TBSA burn, %TBSA grafted, whether sharp debridement prior to grafting in the same procedure was performed or not, use of topical gentamicin intra-operatively, graft outcome (% graft loss), need for regraft, and organism grown were recorded into an excel spread sheet for analysis. The sample included 52 patients. Of these, 17 (31.5%) were female. The median %TBSA grafted was 8% (IQR 4-13%) and similar in both groups. The median days from burn to grafting was 35 days. Thirty-nine patients (75%) had graft Take and 13 (25%) had graft Failure. In the failed group, median % graft failure was 50% (30 - 70%). Of the group with successful graft take, 90% were noted to have had a positive wound culture prior to grafting. A positive wound culture was not found to be a risk factor for graft failure (p=0.993). Despite the positive wound cultures graft take was more than 90 % in 75% of grafts performed and only 2/52 patients required supplementary grafting. We believe that this demonstrates that our local protocol is reasonable in this setting and that waiting for negative wound swabs prior to grafting should not be a reason to delay grafting.

[Umbilical pilonidal sinus - a rare disease?] / Pilonidalsinus i naveln ­ ovanlig diagnos eller stort mörkertal?

Umbilical pilonidal sinus is a rare diagnosis which is characterized by an inflammatory granulomatous reaction to hair shafts penetrating the epidermis. It is most often seen in adolescent male with a hairy abdomen. The patients often present with a history of pain and umbilical discharge. Conservative treatment with hair extraction and personal hygiene is prioritized and surgery is only recommended in recurrent cases. Here one such case is presented, which was resistant to conservative treatment and where surgical excision and primary repair was indicated. No recurrence was observed 6 months postoperatively.

Surviving Sepsis After Burn Campaign.

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 national burn organizations to recommend members to participate in the program. Two members of the ISBI developed specific "patient/population, intervention, comparison and outcome" (PICO) questions that paralleled the 2021 Surviving Sepsis Campaign [1]. SSABC participants 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 sepsis in burn patients. They should be updated on a regular 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.

Documented nutritional therapy in relation to nutritional guidelines post burn injury - a retrospective observational study.

BACKGROUND & AIMS: Intensive nutritional therapy is an essential component of burn care. Regarding post-minor burn injuries, the literature is lacking. The aim of this study was to evaluate documented nutritional 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 to individual nutritional goals post-burn injury. METHODS: A retrospective observational single-centre study including patients admitted between 2017 and 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 divided according to total body surface area burnt (TBSA %) into minor burn injuries (TBSA <20%) and major burn injuries (TBSA ≥20%). Descriptive statistics were used to analyse data. Adherence to guidelines was established 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 44 patients 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 (fat intake <35% of total energy intake and enteral nutrition as prioritized feeding route), 17% (4/24) a moderate 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 of missing 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 minor and major burn injuries. Compared to major burn injuries, lower documented adequacy for both energy and proteins was found in minor burn injuries. Given the disparity between guidelines and documented nutritional therapy, and the lack of specific guidelines for minor burn injuries, there could be a considerable risk of inadequate nutritional therapy post-burn injury.

Development and evaluation of deep learning algorithms for assessment of acute burns and the need for surgery.

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.

A Randomized Trial of Enteral Glutamine for Treatment of Burn Injuries.

BACKGROUND: Glutamine 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. METHODS: In 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. CONCLUSIONS: In patients with severe burns, supplemental glutamine did not reduce the time to discharge alive from the hospital.

Sociodemographic Patterns of Pediatric Patients in Specialized Burn Care in Sweden.

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 Linköping, between 2010 and 2020. Method: This retrospective register-based study used hospital records from the two burn centers combined with information from 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.

[Diathermy can cause deep burns after alcohol preparation or through direct contact]. / Alkoholbaserade tvättlösningar kan ge brännskador vid diatermi.

Around 36 000 people seek care in Sweden due to burns annually. This usually requires repeated wound care and in some case surgery. Iatrogenic burns are rare but may be deep. One cause could be preparation of a patient with alcohol before surgery, or direct skin contact with a diathermic probe. In this case series we present two patients with this type of burns. These cases highlight the potential harm toward the patient, and it is important to have clear guidelines and take precautions when performing a diathermy.

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

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.

Urine Hydrogen Peroxide Levels and Their Relation to Outcome in Patients with Sepsis, Septic Shock, and Major Burn Injury.

Hydrogen peroxide (H2O2) and oxidative stress have been suggested as possible instigators of both the systemic inflammatory response and the increased vascular permeability associated with sepsis and septic shock. We measured H2O2 concentrations in the urine of 82 patients with severe infections, such as sepsis, septic shock, and infections not fulfilling sepsis-3 criteria, in patients with major burn injury with associated systemic inflammation, and healthy subjects. The mean concentrations of H2O2 were found to be lower in patients with severe infections compared to burn injury patients and healthy subjects. Patients with acute kidney injury (AKI), vs. those without AKI, in all diagnostic groups displayed higher concentrations of urine H2O2 (p < 0.001). Likewise, urine concentrations of H2O2 were higher in non-survivors as compared to survivors (p < 0.001) at day 28 in all diagnostic groups, as well as in patients with severe infections and burn injury (p < 0.001 for both). In this cohort, increased H2O2 in urine is thus associated with mortality in patients with sepsis and septic shock as well as in patients with burn injury.

Delayed, Unprovoked, Hemodynamic Collapse with Following Asystole in a Pediatric Patient Following a High-Voltage Injury: A Case Report and Literature Review.

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.

Infection control measures to stop the spread of sequence type 15 OXA-23-producing Acinetobacter baumannii in a Swedish Burn Center.

OBJECTIVE: To describe the course of the outbreak and infection control measures to stop the spread of sequence type 15 OXA-23-producing Acinetobacter baumannii in the Burn Center of Uppsala University Hospital, between November 2014 and the end of April 2015. METHODS: Compliance with hand hygiene, dress code, and cleaning routines were reviewed, the ward's environment was systematically investigated to identify potential environmental sources. Sampling routines for A. baumannii, from patients and environment, were established, and the epidemiological relationship was analysed for all carbapenem-resistant A. baumannii isolates using arbitrarily primed polymerase chain reaction (AP-PCR) and pulsed-field gel electrophoresis (PFGE). RESULTS: A total of 54 patients were treated at the burn intensive care unit during the studied, approximately five months period, and an OXA-23-producing A. baumannii was isolated from nine patients (9/54, 17%), whereof two died (2/9, 22.2%). All isolates shared identical PFGE-genotype patterns and belonged to sequence type 15; AP-PCR was eligible for prompt epidemiological investigations. CONCLUSIONS: Higher awareness and increased compliance with hand hygiene and dress code as well as intensified cleaning protocols of the environment and equipment were successfully established and likely to have led to stop the spread of sequence type 15 OXA-23-producing Acinetobacter baumannii.

A proof-of-concept study on mortality prediction with machine learning algorithms using burn intensive care data.

INTRODUCTION: Burn 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. METHODS: Admission 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. RESULTS: A 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. CONCLUSION: This 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. LAY SUMMARY: Burn injuries are one of the most common traumatic injuries especially in countries with limited prevention and healthcare resources. To treat a patient with large burns who has been admitted to an intensive care unit, it is often necessary to assess the risk of a fatal outcome. Physicians traditionally use simplified scores to calculate risks. One commonly used score, the Baux score, uses age of the patient and the size of the burn to predict the risk of death. Adding the factor of inhalation injury, the score is then called the revised Baux score. However, there are a number of additional causes that can influence the risk of fatal outcomes that Baux scores do not take into account. Machine learning is a method of data modelling where the system learns to predict outcomes based on previous cases and is a branch of artificial intelligence. In this study we evaluated several machine learning methods for outcome prediction in patients admitted for burn injury. We gathered data on 93 patients at admission to the intensive care unit and our experiments show that machine learning methods can reach an accuracy comparable with Baux scores in calculating the risk of fatal outcomes. This study represents a proof of principle and future studies on larger patient series are required to verify our results as well as to evaluate the methods on patients in real-life situations.

Intranasal dexmedetomidine and rectal ketamine for young children undergoing burn wound procedures.

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.

Biosynthetic cellulose compared to porcine xenograft in the treatment of partial-thickness burns: A randomised clinical trial.

AIM: The aim was to compare two dressing treatments for partial-thickness burns: biosynthetic cellulose dressing (BsC) (Epiprotect® S2Medical AB, Linköping, Sweden) and porcine xenograft (EZ Derm®, Mölnlycke Health Care, Gothenburg, Sweden). METHODS: Twenty-four adults with partial-thickness burns were included in this randomized clinical trial conducted at The Burn Centers in Linköping and Uppsala, Sweden between June 2016 and November 2018. Time to healing was the primary outcome. Secondary outcomes were wound infection, pain, impact on everyday life, length of hospital stay, cost, and burn scar outcome (evaluated with POSAS). RESULTS: We found no significant differences between the two dressing groups regarding time to healing, wound infection, pain, impact on everyday life, duration of hospital stay, cost, or burn scar outcome at the first follow up. Burn scar outcome at the 12-month follow up showed that the porcine xenograft group patients scored their scars higher on the POSAS items thickness (p = 0.048) and relief (p = 0.050). This difference was, however, not confirmed by the observer. CONCLUSIONS: The results showed the dressings performed similarly when used in adults with burns evaluated as partial thickness.

Does the estimation of burn extent at admission differ from the assessment at discharge?

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.

First-in-Human Study to Assess the Safety, Tolerability, and Pharmacokinetics of Pirepemat, a Cortical Enhancer, in Healthy Volunteers.

Pirepemat (IRL752) is a cortical enhancer being developed for the prevention of falls in patients with Parkinson disease. This first-in-human, randomized, double-blind, placebo-controlled phase 1 study evaluated safety, tolerability, and pharmacokinetics (PK) of pirepemat administered as oral single ascending doses (10, 35, 75, 175, 350 mg) and multiple ascending doses (100 and 250 mg 3 times daily) for 7 days to healthy male volunteers. Twenty and 24 subjects were randomly assigned in the single ascending dose and multiple ascending doses parts of the study, respectively. Pirepemat was generally well tolerated, although an increased frequency of adverse events of mild intensity within nervous system disorders (headache and dizziness) was seen after administration of 350 mg as a single dose and after multiple doses of 100 and 250 mg. PK of pirepemat showed a linear relationship over the dose range studied and exhibited dose proportionality after multiple-dose administration. Accumulation after 7 days of multiple dosing was minor. Absorption was rapid, with a median time to maximum concentration of 2.0 hours on day 1 and day 7 (100 and 250 mg) and a mean terminal half-life between 3.7 and 5.2 hours. Food intake had no (obvious) impact on PK. The results support 3-times-daily dosing and further clinical development.

Left orbital compartment syndrome and right anterior ischemic optic neuropathy in a patient with severe burns despite non-aggressive fluid resuscitation.

INTRODUCTION: Ophthalmological complications such as orbital compartment syndrome (OCS) and ischemic optic neuropathy are rare complications in patients with burns and have been described in patients where aggressive fluid resuscitation was performed. While OCS requires urgent surgical intervention, no current treatment is established to treat, or prevent, ischemic optic neuropathy in patients with burns. METHODS: The authors report a case of a 38-year-old woman with flame burns including the periorbital regions who developed OCS on the left side and anterior ischemic optic neuropathy (AION) on the right side despite non-aggressive fluid resuscitation. Immediate lateral canthotomy combined with inferior cantholysis was performed on the left side. DISCUSSION AND CONCLUSION: OCS and AION need to be considered as potential complications even in critically ill patients with facial burns who do not receive aggressive fluid resuscitation. Whether an early surgical intervention will lower the risk of AION development is, however, speculative. LAY SUMMARY: Ophthalmological complications such as orbital compartment syndrome and ischemic optic neuropathy are rare complications in patients with burns and have been described in patients where aggressive fluid resuscitation was performed. We present a case of a critically ill patient with severe facial burns who developed orbital compartment syndrome on the left side and anterior ischemic optic neuropathy on the right side even though our patient did not receive aggressive fluid resuscitation.Our case is particular because both of these rare complications are seen in a single patient and neither received aggressive fluid resuscitation. The fact that the patient did not develop ischemic optic neuropathy on the side where the lateral canthotomy was performed (only on the side where the patient had orbital compartment syndrome), this case might raise the discussion of whether an early surgical intervention might lower the risk of ischemic optic neuropathy development in patients with facial burns.

A full-thickness chemical burn to the hand using formic acid-based anti-wart treatment: a case report and literature review.

INTRODUCTION: Chemical burns are comparably rare but often result in full-thickness skin defects with frequent involvement of underlying structures. Hands are the most commonly affected injury site and impaired functional outcome is common. We present a case of an unusual chemical burn to the dorsum of the hand of a child secondary to application of a topical anti-wart treatment containing formic acid. CASE REPORT: An 11-year-old girl was referred to our outpatient department with a full-thickness injury resulting from a chemical burn having used a topical formic acid solution in the treatment of common warts. On examination, a 20-mm circular full-thickness defect was noted to the dorsum of the hand. The extensor tendons were not involved and there were no signs of infection. She required surgical debridement and local flap coverage. The postoperative recovery was unremarkable. CONCLUSION: Through a comprehensive literature review, four common topical solutions used in anti-wart treatment were identified to be associated with burns. Together with our case, this highlights the importance of careful patient education in the usage of common topical over-the-counter treatments.
