Thermal damage to the skin from 8.2 and 95 GHz microwave exposures in swine.

A study of burn thresholds from superficially penetrating radio-frequency (RF) energy at 8.2 and 95 GHz for swine skin was conducted. The study determined the thresholds for superficial, partial-thickness, and full-thickness burn severities after 5 seconds of exposure at power densities of 4-30 W/cm2and 2-15 W/cm2at 8.2 and 95 GHz, respectively. There were significant differences in he burn thresholds at the different severities between the two frequencies due to the large difference in energy penetration depths. Biopsies were collected from each burn site at 1, 24, 72, and 168 hr post exposure. Each sample was assessed by a burn pathologist against 20 histological factors to characterize the damage resulting from these RF overexposures. A one-dimensional, layered digital phantom that utilized realistic values for dielectric and thermal properties was used to explain some observed thresholds. The results of the heating and cooling response of the animal model and histology scores of each exposure are provided to enhance future efforts at simulation of RF overexposures and to establish damage thresholds.

The cost of keeping warm: a relationship between a rise in the cost of domestic energy and burn injuries caused by personal heating equipment.

INTRODUCTION: During 2022-2023, the UK found itself in the midst of a domestic energy crisis, with the average domestic gas and electricity bill rising by 75% between 2019 and 2022. As a result, the use of hot water bottles, radiant heaters, and electric blankets increased. An unintended consequence of this may be an increase in burn injuries caused by misfortune, misuse, or the use of items in a state of disrepair. PURPOSE: The aim of this study was to explore any increase in referrals to a single burns centre in England for injuries caused by hot water bottles, radiant heaters, or electric blankets. METHODS: This was a retrospective study of a prospectively maintained database of referrals. All referrals between January 2022 and January 2023 were selected and compared with the same period from 2020-2021 (before the rise in energy prices). Referrals were screened for the terms "hot water bottle," "electric heater," "electric blanket," and "heater." Total referrals in each period, demographic data (age, gender), anatomical location and the mechanism of injury were compared between cohorts. RESULTS: We found a statistically significant increase in the number of burns relating to heating implements between 2020/21 and 2022/23, rising from 54 to 81 (p = 0.03) - a 50% increase in injuries. Injuries in working age adults increased significantly (52% to 69%, p < 0.05). The most frequently injured area was the leg (30%) followed by the hand (18%). The commonest type of injury described was scald (72%). We found a moderately-strong correlation between the number of referrals and the average cost of energy in 2022-23. CONCLUSION: The number of injuries sustained by people using personal heating equipment is significantly increasing, which correlated with the rise in domestic energy prices. The most affected demographic appears to be working age adults, with wider implications around lost work-time yet to be explored. Further prospective, population-based work is indicated to assess the strength of the correlation seen in this study.

Incidence and predictors of thermal oesophageal and vagus nerve injuries in Ablation Index-guided high-power-short-duration ablation of atrial fibrillation: a prospective study.

AIMS: High-power-short-duration (HPSD) ablation is an effective treatment for atrial fibrillation but poses risks of thermal injuries to the oesophagus and vagus nerve. This study aims to investigate incidence and predictors of thermal injuries, employing machine learning. METHODS AND RESULTS: A prospective observational study was conducted at Leipzig Heart Centre, Germany, excluding patients with multiple prior ablations. All patients received Ablation Index-guided HPSD ablation and subsequent oesophagogastroduodenoscopy. A machine learning algorithm categorized ablation points by atrial location and analysed ablation data, including Ablation Index, focusing on the posterior wall. The study is registered in clinicaltrials.gov (NCT05709756). Between February 2021 and August 2023, 238 patients were enrolled, of whom 18 (7.6%; nine oesophagus, eight vagus nerve, one both) developed thermal injuries, including eight oesophageal erythemata, two ulcers, and no fistula. Higher mean force (15.8 ± 3.9 g vs. 13.6 ± 3.9 g, P = 0.022), ablation point quantity (61.50 ± 20.45 vs. 48.16 ± 19.60, P = 0.007), and total and maximum Ablation Index (24 114 ± 8765 vs. 18 894 ± 7863, P = 0.008; 499 ± 95 vs. 473 ± 44, P = 0.04, respectively) at the posterior wall, but not oesophagus location, correlated significantly with thermal injury occurrence. Patients with thermal injuries had significantly lower distances between left atrium and oesophagus (3.0 ± 1.5 mm vs. 4.4 ± 2.1 mm, P = 0.012) and smaller atrial surface areas (24.9 ± 6.5 cm2 vs. 29.5 ± 7.5 cm2, P = 0.032). CONCLUSION: The low thermal lesion's rate (7.6%) during Ablation Index-guided HPSD ablation for atrial fibrillation is noteworthy. Machine learning based ablation data analysis identified several potential predictors of thermal injuries. The correlation between machine learning output and injury development suggests the potential for a clinical tool to enhance procedural safety.

Acute Burn Care.

LEARNING OBJECTIVES: After studying this article and viewing the videos, the participant should be able to: 1. Describe the current epidemiology of burn injuries. 2. Understand burn pathophysiology and perform a wound assessment. 3. Summarize the initial emergency management of a burn patient. 4. Calculate the anticipated fluid resuscitation requirements for a burn injury, and diagnose the complications of overresuscitation. 5. Describe the diagnosis and management of inhalation injury. 6. List the goals of wound care for superficial and deep burns, and describe the closed dressing technique. 7. Perform excision of a burn wound. 8. Compare various wound closure techniques using autografts and skin substitutes. SUMMARY: Plastic surgeons are essential members of the multidisciplinary burn team. Burn injuries remain common, and plastic surgeons have an opportunity to develop and innovate the field of acute burn care in light of workforce shortages. Burn pathophysiology is complex and dynamic, which informs the challenges encountered during the perioperative phase. Accurate burn wound assessment remains difficult, with implications for diagnosis and management. A systematic approach is required when stabilizing a major burn and/or inhalation injury with newly updated fluid resuscitation and triage guidelines. Wound care continues to evolve, with an emphasis on a closed dressing technique. For deeper burns, new surgical techniques are emerging for surgical débridement, along with improvements to traditional methods of tangential excision. Following excision, a number of established and novel techniques are available to close the wound with either autografts or skin substitutes.

Antecubital Burn Resulting From Antenna Coupling: A Case Report.

CASE: We present the case of a 54-year-old man who underwent elective hip disarticulation complicated by third-degree burn of the left antecubital fossa requiring skin graft. After careful review, it was determined that "antenna coupling" as a result of electrosurgery was the likely cause. We present an experiment demonstrating this phenomenon. CONCLUSION: Antenna coupling is a real but rare cause of intraoperative burns not previously described in the orthopaedic literature. Care should be taken to avoid coiling or running bovie or other electrosurgical device cords with other metallic cords or corded devices.

Never events in plastic surgery: An analysis of surgical burns and medical malpractice litigation.

INTRODUCTION: Burns and fires in the operating room are a known risk and their prevention has contributed to many additional safety measures. Despite these safeguards, burn injuries contribute significantly to the medical malpractice landscape. The aim of the present study is to analyze malpractice litigation related to burn and fire injuries in plastic and reconstructive surgery, identify mechanisms of injury, and develop strategies for prevention. METHODS: The Westlaw and LexisNexis databases were queried for jury verdicts and settlements in malpractice lawsuits related to burn and fire injuries that occurred during plastic surgery procedures. The Boolean terms included "burn & injury & plastic", "fire & injury & "plastic surg!"" in Westlaw, and "burn & injury & "plastic surg!"", "fire & injury & "plastic surg!"" in LexisNexis. RESULTS: A total of 46 cases met the inclusion criteria for this study. Overheated surgical instruments and cautery devices were the most common mechanisms for litigation. Plastic surgeons were defendants in 40 (87%) cases. Of the included cases, 43% were ruled in favor of the defendant, while 33% were ruled in favor of the plaintiff. Mishandling of cautery devices 6 (13%), heated surgical instruments 6 (13%), and topical acids 2 (4%) were the most common types of errors encountered. CONCLUSION: Never events causing burn injury in plastic and reconstructive surgery are ultimately caused by human error or neglect. The misuse of overheated surgical instruments and cauterizing devices should be the focus for improving patient safety and reducing the risk of medical malpractice. Forcing functions and additional safeguards should be considered to minimize the risk of costly litigation and unnecessary severe harm to patients.

Ultra-restrictive red blood cell transfusion strategies in extensively burned patients.

In recent years, due to the shortage of blood products, some extensive burn patients were forced to adopt an "ultra-restrictive" transfusion strategy, in which the hemoglobin levels of RBC transfusion thresholds were < 7 g/dl or even < 6 g/dl. This study investigated the prognostic impacts of ultra-restrictive RBC transfusion in extensive burn patients. This retrospective multicenter cohort study recruited extensive burns (total body surface area ≥ 50%) from three hospitals in Eastern China between 1 January 2016 and 30 June 2022. Patients were divided into an ultra-restrictive transfusion group and a restrictive transfusion group depending on whether they received timely RBC transfusion at a hemoglobin level < 7 g/dl. 1:1 ratio propensity score matching (PSM) was performed to balance selection bias. Modified Poisson regression and linear regression were conducted for sensitive analysis. Subsequently, according to whether they received timely RBC transfusion at a hemoglobin level < 6 g/dl, patients in the ultra-restrictive transfusion group were divided into < 6 g/dl group and 6-7 g/dl group to further compare the prognostic outcomes. 271 eligible patients with extensive burns were included, of whom 107 patients were in the ultra-restrictive transfusion group and 164 patients were in the restrictive transfusion group. The ultra-restrictive transfusion group had a significantly lower RBC transfusion volume than the restrictive transfusion group (11.5 [5.5, 21.5] vs 17.3 [9.0, 32.5] units, p = 0.004). There were no significant differences between the two groups in terms of in-hospital mortality, risk of infection, hospital length of stay, and wound healing time after PSM or multivariate adjustment (p > 0.05). Among the ultra-restrictive transfusion group, patients with RBC transfusion threshold < 6 g/dl had a significantly higher hospital mortality than 6-7 g/dl (53.1% vs 21.3%, p = 0.001). For extensive burn patients, no significant adverse effects of ultra-restrictive RBC transfusion were found in this study. When the blood supply is tight, it is acceptable to adopt an RBC transfusion threshold of < 7 g/dL but not < 6 g/dL.

Is multiple wavelength diode laser for facial contouring safe?

The multiple wavelength diode laser (MWDL) is a sophisticated device designed to target deeper skin layers by emitting various wavelengths. Its unique feature is the ability to deliver heat to specific depths within the tissue using different wavelengths while simultaneously cooling the skin surface. Recent research by Choi et al. suggests that wavelengths of 755 and 810 nm can induce carbonization in hair follicles, while the 1064 nm wavelength penetrates deeper into tissues. MWDL has been proposed for fat redistribution in aging, but concerns have been raised regarding ocular safety and potential tissue damage, particularly when used near the eyes. Studies have shown ocular injuries during cosmetic laser procedures, emphasizing the need for robust ocular protection and safety protocols. Additionally, there are reports of internal ischemic necrosis and burns, highlighting the importance of precise energy settings and parameter management. While MWDL shows promise, further research and comprehensive guidelines are needed to ensure safe and effective usage in clinical practice.

An Unusual Pediatric Case of an Insidious Thermal Airway Injury Without Initial Signs of Facial or Intraoral Scalding.

Thermal airway injuries, usually accompanied by facial burns, require emergency management. We encountered a pediatric case of a late airway-scalding injury without any initial signs of scalding on the face or inside the oral cavity. A 16-month-old boy was accidentally exposed to boiling water from overhead and developed tachypnea and dyspnea at 8 h after the injury. When he visited our hospital at 12 h after the injury, there were no scalding-related findings on his face or inside his oral cavity; however, severe laryngeal edema was observed, which required emergency intubation. Thermal airway injuries can occur later, even if there is no evidence of facial or oral scalding immediately after the injury. Airway injuries should be considered when a patient has been exposed to hot water from overhead.

Cold burn injuries in the United Kingdom: retain-->A 5-year cohort study of patients presenting to a regional burn unit.

AIMS: To assess the aetiology, management and outcomes of cold burn injuries presenting to a regional burn unit in the United Kingdom. METHODS: Retrospective cohort study of consecutive patients over a 5-year period (2018-2022). RESULTS: Sixty-two patients (M:F 34:38; median age 23.5 years) were identified. The most common aetiology was aerosol (n = 28, 45.2%). Seven (11.5%) injuries were sustained during a social media or peer 'challenge' and 19 (31.2%) were self-harm, of whom 5 (26.3%) were inpatients on a mental health ward at the time of injury. All 'challenge' and self-harm injuries were caused by aerosol. Patients with 'challenge' injury were younger than those with self-harm (p = .007) and non-intentional injuries (p < .001). A greater proportion of self-harm injuries were in female patients compared with non-intentional injuries (p < .001). Median total body surface area (TBSA) was 0.35% (IQR: 0.3). Most burns were superficial partial thickness (n = 35, 56.5%), followed by deep dermal (n = 18, 29.0%), full-thickness (n = 8, 12.9%), and superficial (n = 1, 1.6%). The upper limb was most frequently affected (n = 35, 56.5%). Aetiology and a non-intentional, 'challenge' or self-harm injury did not affect TBSA (p = 0.776 and p = 0.364) or depth (p = 0.353 and p = 0.381). Five (8.1%) patients underwent autografting. The median time to healing was 17 days (range: 7-45, IQR: 22.75). Follow-up ranged from 1 to 173 weeks. CONCLUSIONS: The incidence of cold burns has increased when compared with previous literature. A disproportionate number of cold burns are self-inflicted using aerosols, either as self-harm or because of social media or peer 'challenges'. Other emerging aetiologies include non-intentional skin contact with nitrous oxide containers during its recreational use.

Scalding saline injuries: Preventing a rare but serious event in medical litigation.

This study aimed to investigate the causes, outcomes, and compensation amounts of saline-induced perioperative burns, a rare but entirely preventable event. Saline-induced burns pose a significant risk to patients, and understanding the factors associated with such incidents is crucial for improving patient safety. Previous studies highlighted the use of hot saline bags and solution during medical procedures as a potential cause of these burns. A retrospective analysis of cases involving perioperative saline-induced burns was conducted using the Westlaw and Lexis Nexis legal databases. Eight relevant cases were identified and analyzed to determine the causes, outcomes, and compensation amounts. Hot saline bags used for positioning and hot saline solution were identified as the primary causes of saline-induced burns. Out of the eight cases analyzed, four resulted in a favorable verdict for the plaintiff, three cases were settled, and one case was in favor of the defense. Compensation amounts ranged from no monetary compensation to over one million dollars. This study highlights the need for increased awareness among medical professionals regarding the risks associated with saline-induced burns, and the importance of implementing guidelines for the safe use of hot saline bags and solution. Together these measures can hopefully mitigate the occurrence of these preventable incidents, improve patient safety, and reduce medicolegal exposure.

Aetiology of bioethanol related burn accidents: A qualitative study.

BACKGROUND: Since insight into the motivation of behaviour in bioethanol related burn accidents is lacking, this study aimed to qualitatively examine influencing factors in bioethanol related burn accidents. In order to identify target points for effective burn prevention. METHODS: Patients previously admitted with bioethanol related acute non-intentional burn injury to the three Dutch burn centres were eligible. One interviewer conducted fourteen semi-structured interviews. Interviews were transcribed and coded by two independent researchers. Conclusions were drawn based on generalised statements on the concerned topics. RESULTS: Four overall themes in influencing factors were found, namely 1) motivation; including non-designated use and impaired judgement, 2) knowledge and education; including unknown product and properties and information overload, 3) risk perception; including poor recognisability of risks and preferred trial and error and 4) thresholds; including easy availability and unclear liability. CONCLUSION: Trust in consumers may be over-estimated, as proper use cannot be expected. To prevent future bioethanol related burn incidents, thresholds for obtaining and using bioethanol should be increased, safe alternatives to ignite open fires and wood stoves should be provided and knowledge and warnings should be improved.

Death on New Year's Eve caused by illegal fireworks-a firework shell.

During the turn of the year, injuries caused by fireworks occur in Germany every year. According to the professional associations, the Unfallkrankenhaus Berlin, for example, treats an average of 50 injuries caused by fireworks on New Year's Eve. Patients come with burns, soft tissue injuries, or fractures; eyes and hands are particularly frequently affected. Again and again, there are also very serious or even fatal injuries. The background is usually the improper or illegal use of larger fireworks. Smaller fireworks such as sparklers, bangers, or smaller rockets are available in Germany in most supermarkets, and their use is permitted from the age of 12 or 18. However, the use of larger fireworks in Germany requires proof of an official permit to handle pyrotechnic objects, which is why they are often acquired abroad. The following report describes such a case. Shortly after the turn of the year 2022, a young man died as a result of an explosive effect on the facial skull after using an illegal firework shell. The case is discussed with regard to the autopsy findings, the possible cause of the accident, and the type of firework used.

Changing Epidemiology and Outcome of Pediatric Thermal Burn Injury in South Western Nigeria.

The pediatric age group has been noted to be particularly vulnerable to burn injuries. Burn is the fifth most common cause of childhood injuries. Nigeria has a very young population with a median age of 18.1 years. Scald is the most common form of burn injuries in this age group globally; however, previous reports from our institution found flame to be the most common form of burn in pediatric age. The most recent report from 13 years ago still maintained flame as the most common cause of pediatric burn injury. This study was carried out to determine the changes in epidemiology and outcome of pediatric thermal burn injury. This was a retrospective study carried out between January 2013 and December 2022. Data were analyzed using the statistical package for social sciences software version 23. The significance was set at a P-value of .05. Two hundred and sixty-five children presented with thermal burn with a male-to-female ratio of 1.3:1. 63.4% occurred in children 0-5 years. Scald (59.6%) was the most common cause of injury. Most flame injuries in females were due to liquified petroleum gas cookstove explosion, while petrol explosion was the most common cause in males (P ≤ .001). There is a yearly increase in burn depth (P = .009). Most inhalation injuries occurred in those aged 11-16 years (P = .006). Mortality rate was 10.2%, with total body surface area burned (P ≤ .001), burn depth (P ≤ .001), and inhalation injury (P ≤ .001) associated with increasing mortality. Scald is now the most common cause of thermal burn in our institution, with a remarkable reduction in mortality rate.

Domestic Cylinder Blasts: A Neglected Torpedo.

High-pressure cylinders are used to store liquefied petroleum gas (LPG). An instant and swift explosion of these cylinders can result in serious burn injuries. This current research was conducted to study the epidemiological characteristics of LPG-related burns to highlight a major public health issue. Analysis was conducted on patients with LPG-related burns over a span of 10 years admitted to our center between January 2011 and December 2020. The data recorded included demographic features, site of burn, %TBSA, associated injuries, and outcomes. The variable data were documented for every patient in a Microsoft Excel file and analyzed by IBM SPSS version 25.0. Over the span of 10 years, 678 patients were affected by LPG-related accidents. The peak incidence was seen in 2019 when there was a surge to 18.03%. The patient's age ranged from 1 to 79 years, with a median of 40.86 ± 15.27 years. Of the 678 patients, 52.50% were males and 47.50% were females. The majority (57.96%) of patients had a total BSA of >60% and 86.72% were diagnosed with inhalation injury. The majority of burns (84.66%) occurred at home. The mean hospital stay was 24.5 days. The total mortality rate was 59.58%. This study concludes that LPG cylinder blast is a preventable cause that can be minimized by making people aware of its safe use and by arranging awareness programs at every national level.

Suspected Burn From a 9-Voltage Battery.

Advancements in technology allow for the utilization of low-voltage battery-powered devices for patients admitted to the hospital. There have been rare cases of burns due to leakage of the internal contents from low-voltage batteries, but to date, there have been no reports of electrical burns caused by low-voltage batteries. We present the case of an 89-year-old female who presented to the general surgery service with a suspected electrical burn from laying on a 9-volt battery. The patient underwent operative debridement with no evidence of a deeper injury. The patient continues to follow up with an outpatient wound clinic and is healing well. This case highlights the importance of teaching and raising awareness of all small devices that may become entangled or lost in patients' linens, such as 9-volt telemetry batteries, to prevent harm.

Burn Injuries From TikTok Challenges: A Brief Report.

Social media (e.g., TikTok) challenge is a relatively new phenomenon wherein a user creates and posts videos performing an often-dangerous task. The ease of access and availability of social media in recent times make teens and young adults susceptible to these viral Internet challenges and accidental injury. The severity, morbidity, and mortality of burn injuries from social media challenges have not readily been documented in the medical literature. In this brief report, we present three cases of accidental burns after attempting social media challenges involving boiling water or flame. The injuries ranged from superficial partial thickness burns to 24% total body surface area (TBSA) full thickness burns. Online challenges show the potential for severe injury and disability and underlie the importance of awareness and education of the public, further research into the usage of TikTok and other media platforms, and early referral to the American Burn Association recognized center.

Skin branding for jaundice in children: A brutal cultural dermatosis.

Dermatological conditions associated with socio-cultural and religious practices, known as "cultural dermatoses," are commonly seen in medical practice. This article presents seven cases of children who underwent skin branding for jaundice in Southern India. Skin branding, a traditional healing method, involves applying heated objects to cause third-degree burns. Healthcare providers should be aware of these cultural practices to avoid misdiagnosis.

No lockdown for pediatric burns.

BACKGROUND: The health crisis related to the COVID-19 pandemic led to an unprecedented situation in France: complete lockdown. The population had to live confined with their families, which often meant that parents telecommuted while caring for their children. However, daily risks remained more than ever at the forefront. The aim of this study was to assess the epidemiology of burns among children during three different periods of family time: school time, vacation, and lockdown. METHODS: A single-center retrospective study was conducted at Tours University Hospital. All pediatric surgical emergency room visits recorded from February 10, 2020 to March 31, 2020 were included. The three aforementioned periods were assessed. RESULTS: During lockdown there were significantly more burns compared to other injuries (p = 0.004). Preschool-age children suffered significantly more from burns during the same period (p = 0.029). There were no significant differences for nursery school (p = 0.522), primary school (p = 0.519), middle school (p = 0.613), and high school (p = N) children. CONCLUSION: This study underlines the need to establish a targeted prevention campaign geared toward a complicated geopolitical situation a pandemic that might occur again.
