Abstract
OBJECTIVES To describe dermoid cyst formation as an uncommon complication of the pinch grafting technique in horses. STUDY DESIGN Case report. ANIMAL A 8 year old Arabian gelding. METHODS Clinical presentation, imaging, treatment, and histopathology records were reviewed. The horse originally presented due to delayed healing of a laceration to the distal aspect of the metatarsus. The wound was treated initially with debridement and it was allowed to fill with healthy granulation tissue prior to pinch grafting. Two months after grafting, the horse started to show self-mutilation behavior targeting the wound site. Ultrasonographic examination revealed the presence of cystic lesions in the subcutaneous tissue in the wound bed and adjacent to the long digital extensor tendon. RESULTS Treatment involved surgical excision of the cysts, which resulted in a resolution of the self-mutilation episodes. The specimens were submitted for histopathological investigation, which revealed findings compatible with dermoid cyst formation, suspected to be secondary to the skin-grafting procedure. CONCLUSION Dermoid cysts formation should be considered as a potential differential diagnosis for skin graft complications in horses.

Abstract
INTRODUCTION Major traumatic injuries are a known risk factor for persistent opioid use, but data describing the relationship between specific traumatic injuries and opioid use is lacking. METHODS We used insurance claims data from January 1, 2001 to December 31, 2020 to estimate the incidence of new persistent opioid use in three hospitalized trauma populations: individuals hospitalized after burn injury (3809, 1504 of whom required tissue grafting), individuals hospitalized after motor vehicle collision (MVC; 9041), and individuals hospitalized after orthopedic injury (47, 637). New persistent opioid use was defined as receipt of ≥1 opioid prescriptions 90-180 days following injury in an individual with no opioid prescriptions during the year prior to injury. RESULTS New persistent opioid use was observed in 12% (267/2305) of individuals hospitalized after burn injury with no grafting, and 12% (176/1504) of burn injury patients requiring tissue grafting. In addition, new persistent opioid use was observed in 16% (1454/9041) of individuals hospitalized after MVC, and 20% (9455/47, 637) of individuals hospitalized after orthopedic trauma. In comparison, rates of persistent opioid use in all trauma cohorts (19%, 11, 352/60, 487) were greater than the rates of persistent opioid use in both non-traumatic major surgery (13%) and non-traumatic minor surgery (9%). CONCLUSIONS These data demonstrate that new persistent opioid use frequently occurs in these common hospitalized trauma populations. Improved interventions to reduce persistent pain and opioid use in patients hospitalized after these and other traumas are needed.

Comparing the Efficacy of Diluted Lidocaine Solution and Placebo in Reducing Pain Perception During Burn Wound Dressing Change. J Burn Care Res 2024; 45:200-204.

Abstract
The aim of this study was to evaluate the effectiveness of 0.08% diluted lidocaine solution during and after wound dressing procedures for patients with burn injuries. Fifty burn patients aged 18-60 years, with burns ranging from 30% to 60%, were divided into intervention and control groups. The intervention group received dressings diluted with 0.08% lidocaine solution, while the control group received a placebo. Vital signs were continuously monitored before, during, and after the application of new dressings. Pain was assessed using the Visual Analog Scale (VAS) checklist before and after the dressing change in both groups. The study included 25 participants in the intervention group with a mean age of 40.2 ± 6.5 and 25 participants in the control group with a mean age of 39.1 ± 6.8. The groups were comparable in terms of baseline characteristics, including gender, age, weight, height, body mass index, percentage and degree of burns, as well as average morphine intake. No significant differences were observed in vital signs or pain scores before and after dressing changes between the 2 groups. However, the intervention group reported significantly lower pain scores during the dressing change compared to the control group (P < .001). Diluted lidocaine solution during wound dressing procedures can reduce pain in burn patients. Further research with larger sample sizes is needed to establish the safety and efficacy of this technique. This study suggests that lidocaine can be a useful tool in the management of pain during dressing changes for burn patients.

Front Med (Lausanne) 2022; 9:997183.

Abstract
Itch and pain are common after burns. Neuropathic mechanisms may underlie both modalities but remain not well-understood. This study aims to prospectively document neuropathic pain symptoms and to identify potential itch symptom profiles that differ regarding duration and co-occurrence with neuropathic pain which may inform underlying pathophysiological mechanisms and respond to different treatments. Adult burn survivors (n = 192) self-reported itch and neuropathic pain at 2 weeks post-discharge, 3, 6, 12, and 18 months post-burn. Based on the presence of itch and pain symptoms over time, participants were allocated to one itch profile: transient itch/pain, chronic itch, or chronic itch & pain. Profiles were compared on itch intensity over time using General Linear Modeling. Age, gender, burn severity, posttraumatic stress (PTS) symptoms and baseline itch intensity were examined as potential predictors of the profiles in a Multi-nominal regression analysis. Neuropathic pain occurred in 54% after discharge which decreased to 24% 18 months later. Itch intensity was highest in the chronic itch & pain profile. Compared to the transient itch profile, the chronic itch & pain profile was associated with higher burn severity and more PTS symptoms. Compared to the chronic itch profile, the chronic itch & pain profile was associated with more PTS symptoms. Findings suggest that biological and psycho-dermatological processes underlie both chronic neuropathic pain and itch processes in burn scars. Further research should elucidate the mechanisms underlying the different itch profiles, with specific focus on skin innervation and psychological factors.

Abstract
ABSTRACT Clinically significant new or worsening pain (CSNWP) is a common, yet often overlooked, sequelae of sexual assault. Little is known regarding factors influencing the development of CSNWP in sexual assault survivors. The current study used data from a recently completed prospective study to evaluate whether posttraumatic alterations in arousal and reactivity in the early aftermath of sexual assault influence the transition from acute to clinically significant new or worsening persistent pain. Women ≥ 18 years of age (n = 706) presenting for emergency care after sexual assault to 13 emergency care sites were enrolled in the study. Women completed assessments at the time of presentation as well as at 1 week (n = 706, 100%) and 6 weeks (n = 630, 91%). Nearly 70% of women reported CSNWP at the time of emergency care (n = 475, 69%), which persisted to 6 weeks in approximately 2 in 5 survivors (n = 248, 41%). A structural equation model adjusted for age, race, past trauma exposure, and preassault pain levels suggested that posttraumatic alterations in arousal/reactivity symptoms 1 week after assault partially mediated the transition from acute to persistent CSNWP. A significant portion (41%) of women sexual assault survivors develop CSNWP 6 weeks postassault. Posttraumatic arousal/reactivity symptoms in the early aftermath of assault contribute to CSNWP development; such symptoms are potential targets for secondary preventive interventions to reduce chronic postassault pain.

Abstract
BACKGROUND Patient-reported outcomes are important for understanding recovery after burn injury, benchmarking service delivery and measuring the impact of interventions. Patient-Reported Outcomes Measurement Information System (PROMIS)-29 domains have been validated for use among diverse populations though not among burn survivors. The purpose of this study was to examine validity and reliability of PROMIS-29 scores in this population. METHODS The PROMIS-29 scores of physical function, anxiety, depression, fatigue, sleep disturbance, ability to participate in social roles, and pain interference were evaluated for validity and reliability in adult burn survivors. Unidimensionality, floor and ceiling effects, internal consistency, and reliability were examined. Differential item functioning was used to examine bias with respect to demographic and injury characteristics. Correlations with measures of related constructs (Community Integration Questionnaire, Satisfaction with Life Scale, Post-Traumatic Stress Checklist-Civilian, and Veteran's Rand-12) and known-group differences were examined. RESULTS Eight hundred and seventy-six burn survivors with moderate to severe injury from 6 months to 20 years postburn provided responses on PROMIS-29 domains. Participants' ages ranged from 18 years to 93 years at time of assessment; mean years since injury was 3.4. All PROMIS domain scores showed high internal consistency (Cronbach's α = 0.87-0.97). There was a large ceiling effect on ability to participate in social roles (39.7%) and physical function (43.3%). One-factor confirmatory factor analyses supported unidimensionality (all comparative fit indices >0.95). We found no statistically significant bias (differential item functioning). Reliability was high (>0.9) across trait levels for all domains except sleep, which reached moderate reliability (>0.85). All known-group differences by demographic and clinical characteristics were in the hypothesized direction and magnitude except burn size categories. CONCLUSION The results provide strong evidence for reliability and validity of PROMIS-29 domain scores among adult burn survivors. Reliability of the extreme scores could be increased and the ceiling effects reduced by administering PROMIS-43, which includes six items per domain, or by administering by computerized adaptive testing. LEVEL OF EVIDENCE Diagnostic Test or Criteria, level III.

Abstract
ABSTRACT Biologic factors that predict risk for and mediate the development of common outcomes of trauma exposure such as chronic posttraumatic pain (CPTP) are poorly understood. In the current study, we examined whether peritraumatic circulating 17β-estradiol (E2) levels influence CPTP trajectories. 17β-estradiol levels were measured in plasma samples (n = 254) collected in the immediate aftermath of trauma exposure from 3 multiethnic longitudinal cohorts of men and women trauma survivors. Chronic posttraumatic pain severity was evaluated 6 weeks, 6 months, and 1 year after traumatic stress exposure. Repeated measures mixed models were used to test the relationship between peritraumatic E2 levels and prospective CPTP. Secondary analyses in a nested cohort assessed the influence of participant body mass index on the E2-CPTP relationship. In women, a statistically significant inverse relationship between peritraumatic E2 and CPTP was observed (β = -0.280, P = 0.043) such that higher E2 levels predicted lower CPTP severity over time. Secondary analyses identified an E2 * body mass index interaction in men from the motor vehicle collision cohort such that obese men with higher E2 levels were at greater risk of developing CPTP. In nonobese men from the motor vehicle collision cohort and in men from the major thermal burn injury cohort, no statistically significant relationship was identified. In conclusion, peritraumatic circulating E2 levels predict CPTP vulnerability in women trauma survivors. In addition, these data suggest that peritraumatic administration of E2 might improve CPTP outcomes for women; further research is needed to test this possibility.

Abstract
Chronic pain is a significant co-morbidity of burn injury affecting up to 60% of survivors. Currently, no treatments are available to prevent chronic pain after burn injury. Accumulating evidence suggests that omega-3 fatty acids (O3FA) improve symptoms across a range of painful conditions. In this study, we evaluated whether low peritraumatic levels of O3FA predicts greater pain severity during the year after burn injury. Burn survivors undergoing skin autograft were recruited from three participating burn centers. Plasma O3FA (n=77) levels were assessed in the early aftermath of burn injury using liquid chromatography/mass spectrometry and pain severity was assessed via the 0-10 numeric rating scale for 1 year following burn injury. Repeated-measures linear regression analyses were used to evaluate the association between peritraumatic O3FA concentrations and pain severity during the year following burn injury. Peritraumatic O3FA concentration and chronic pain severity were inversely related; lower levels of peritraumatic O3FA predicted worse pain outcomes (β=-.002, p=.020). Future studies are needed to evaluate biological mechanisms mediating this association and to assess the ability of O3FA to prevent chronic pain following burn injury.

Abstract
Major thermal burn injuries result in approximately 40,000 hospitalizations in the United States each year. Chronic pain affects up to 60% of burn survivors, Black Americans have worse chronic pain outcomes than White Americans. Mechanisms of chronic pain pathogenesis after burn injury, and accounting for these racial differences, remain poorly understood. Due to socioeconomic disadvantage and differences in skin absorption, Black Americans have an increased prevalence of Vitamin D deficiency. We hypothesized that peritraumatic Vitamin D levels predict chronic pain outcomes after burn injury and contribute to racial differences in pain outcomes. Among burn survivors (n=77, 52% White, 48% Black, 77% male), peritraumatic Vitamin D levels were more likely to be deficient in Blacks vs. Whites (27/37 (73%) vs. 14/40 (35%), p<.001). Peritraumatic Vitamin D levels were inversely associated with chronic post-burn pain outcomes across all burn injury survivors, including those who were and were not Vitamin D deficient, and accounted for approximately 1/3 of racial differences in post-burn pain outcome. Future studies are needed to evaluate potential mechanisms mediating the effect of Vitamin D on post-burn pain outcomes and the potential efficacy of Vitamin D in improving pain outcomes and reducing racial differences.

Abstract
Prominent clinical problems related to the skin-nerve interface include barrier dysfunction and erythema, but it is the symptoms of pain and itch that most often lead patients to seek medical treatment. Tissue-engineered innervated skin models provide an excellent solution for studying the mechanisms underlying neurocutaneous disorders for drug screening, and cutaneous device development. Innervated skin substitutes provide solutions beyond traditional monolayer cultures and have advantages that make them preferable to in vivo animal studies for certain applications, such as measuring somatosensory transduction. The tissue-engineered innervated skin models replicate the complex stratified epidermis that provides barrier function in native skin, a feature that is lacking in monolayer co-cultures, while allowing for a level of detail in measurement of nerve morphology and function that cannot be achieved in animal models. In this review, the advantages and disadvantages of different cell sources and scaffold materials will be discussed and a presentation of the current state of the field is reviewed. Impact statement A review of the current state of innervated skin substitutes and the considerations that need to be addressed when developing these models. Tissue-engineered skin substitutes are customizable and provide barrier function allowing for screening of topical drugs and for studying nerve function.

Abstract
AIM Children's burns care in Australasia is performed by paediatric surgeons and by plastic surgeons. The aim was to determine practices regarding the donor site wound (DSW), and to explore any differences by training scheme or nature of unit (paediatric vs. mixed). METHODS Online survey of Australasian burns surgeons. RESULTS Forty surgeons responded. 23/40 paediatric surgeons, 23/40 worked in a stand-alone children's burns unit. All used powered dermatomes. Alginates were the most common DSW dressing. Idealised dressings favour patient factors over cost. Plastic, and mixed-practice, surgeons use a broader range of dermatome settings in children >1 year. Mixed practice surgeons use thicker settings. All surgeons see pain as a common DSW problem. Paediatric surgeons recognise itch as a problem. CONCLUSIONS While there are differences related to training scheme and the mix of patients being treated, there is a broader commonality of practice.

Abstract
Burn-injured patients provide unique challenges to those providing anaesthesia and pain management. This review aims to update both the regular burn anaesthetist and the anaesthetist only occasionally involved with burn patients in emergency settings. It addresses some aspects of care that are perhaps contentious in terms of airway management, fluid resuscitation, transfusion practices and pharmacology. Recognition of pain management failures and the lack of mechanism-specific analgesics are discussed along with the opioid crisis as it relates to burns and nonpharmacological methods in the management of distressed patients.

Abstract
Approximately three quarters of major thermal burn injury (MThBI) survivors suffer from hypertrophic scarring (HTS) and over half experience chronic pain or itch. In survivors of MThBI, HTS and chronic pain or itch are considered one of the greatest unmet challenges of postburn injury care and psychosocial reintegration. Although scarring, itch, and pain have been clinically associated, there are no prospective, multisite studies examining tissue autograft site pain or itch and scar outcomes. The authors collected a representative cohort (n = 56) of MThBI survivors who received autografting within 14 days of injury and evaluated graft-site pain or itch severity (0-10 Numeric Rating Scale) and HTS using a validated scar photograph assessment scale 6 months following MThBI. Given that stress is known to influence wound healing, the authors also assessed the relationship between previous trauma exposure, peritraumatic stress, preburn overall health (SF-12), scarring, and chronic pain or itch severity using Spearman's correlation. Association between HTS and chronic pain or itch was significant in a linear regression model adjusted for age, sex, and ethnicity (β = 0.2, P = .033 for pain, β = 0.2, P = .019 for itch). Results indicate that prior trauma exposure is inversely correlated (r = -.363, P = .030) with scar severity, but not pain or itch severity 6 months after MThBI. Study results suggest that preburn chronic pain or itch is associated with pathological scarring 6 months following MThBI. Results also indicate that stress may improve scarring after MThBI. Further work to understand the mechanisms that underlie both HTS and chronic pain or itch and their relationship to chronic stress is critical to the development of novel therapies to assist burn survivors recover.

Abstract
Abstract
Adult-acquired burn injuries are a life-altering event that can lead to debilitating functional or psychological impairments. With advancements in health care resulting in decreased mortality rates, survivors of burn injuries can expect to live longer. This warrants a shift in focus to better understand what happens to adults once they are discharged from the hospital into the community. Therefore, the purpose of this scoping review was to map the literature regarding the long-term outcomes of community-dwelling adult-acquired burn survivors. A computer-assisted literature search was conducted on literature from January 1, 2000 to August 31, 2018 utilizing four large databases (MEDLINE, EMBASE, CINHAL, and PsycINFO). Articles were included if they had a minimum of five individuals with a burn injury as a result of an accidental injury who were at least 18 years of age at the time of injury. Fifty-four articles were found suitable for inclusion in this review. The majority of studies were conducted in the United States and were longitudinal in design. Four themes were apparent from the articles: postburn complications, psychosocial outcomes, quality of life, and community participation. Data are lacking with respect to outcomes more than 5 years postburn as well as qualitative research. Furthermore, more literature is needed to understand the impact of postburn complications, coping strategies, and posttraumatic growth as well as barriers to community participation. Overall, there is an emerging body of literature that describes the long-term outcomes of adult-acquired burn survivors up to 5 years postburn.

Abstract
Over the past decade there has been an increasing reliance on strong opioids to treat acute and chronic pain, which has been associated with a rising epidemic of prescription opioid misuse, abuse, and overdose-related deaths. Deaths from prescription opioids have more than quadrupled in the USA since 1999, and this pattern is now occurring globally. Inappropriate opioid prescribing after surgery, particularly after discharge, is a major cause of this problem. Chronic postsurgical pain, occurring in approximately 10% of patients who have surgery, typically begins as acute postoperative pain that is difficult to control, but soon transitions into a persistent pain condition with neuropathic features that are unresponsive to opioids. Research into how and why this transition occurs has led to a stronger appreciation of opioid-induced hyperalgesia, use of more effective and safer opioid-sparing analgesic regimens, and non-pharmacological interventions for pain management. This Series provides an overview of the epidemiology and societal effect, basic science, and current recommendations for managing persistent postsurgical pain. We discuss the advances in the prevention of this transitional pain state, with the aim to promote safer analgesic regimens to better manage patients with acute and chronic pain.

Pain and itch outcome trajectories differ among European American and African American survivors of major thermal burn injury. Pain 2018; 158:2268-2276.

Abstract
More than half of individuals experiencing major thermal burn injury (MThBI) receive an autologous skin graft (autograft), in which skin is removed from a healthy "donor" site and transplanted to the burn site. Persistent pain and itch at the graft site are major causes of suffering and disability in MThBI survivors. African Americans have a higher risk of MThBI, and in other clinical settings African Americans experience a greater burden of pain and itch relative to European Americans. However, to our knowledge, ethnic differences in skin graft site pain and itch outcomes after MThBI have not been assessed. We evaluated skin graft site pain and itch severity (0-10 Numeric Rating Scale [NRS]) over 1 year in a prospective multicenter cohort sample of African Americans and European Americans. In adjusted linear mixed models, African Americans experienced a slower rate of pain resolution in the acute phase of recovery (β = -0.05 vs -0.08 NRS points per day, P < 0.001), which resulted in a higher pain severity in the persistent phase of recovery (NRS mean difference = 1.21, 95% confidence interval [0.12-2.29]), although not statistically significant after correction for multiple comparisons. African Americans also experience greater itch severity in 6 weeks to 12 months after burn injury compared with European Americans (NRS mean difference = 1.86 [0.80-2.93]), which results from a faster rate of itch development in African Americans in the acute recovery phase after burn injury. Future studies may improve outcomes in African Americans and lead to new pathogenic insights that benefit all burn injury survivors.
