Scar outcomes for conservatively managed children post burn injury: A retrospective study.

Hypertrophic scarring is a significant complication post burn injury, especially for delayed healing after 3 weeks. Burn injuries healing prior to 3 weeks also have the potential to develop hypertrophic scarring, even when prescribed prophylactic conservative scar interventions. A retrospective chart audit reviewed 326 burn patients treated at a paediatric tertiary hospital from 2014 to 2019 who sustained a partial thickness burn, healed >14 days and did not receive skin grafting. A scar was deemed hypertrophic if >1 mm in height. Early hypertrophic scar prevalence was defined as 3-6 months post burn, while persistent hypertrophic scarring was defined as 12-18 months post burn. Median days to wound closure was 18. The prevalence of early and persistent hypertrophic scarring was 56.1% and 16.3%, respectively. Seventeen (5.2%) children underwent medical interventions for scar modulation. Early signs of hypertrophic scarring were seen in just over half the patients presenting to burn therapy and despite scar intervention, persistent hypertrophic scarring was seen in 16.3%. At both time points, just over half of the children presenting healed between 14 and 21 days. Therefore, children healing prior to 21 days have potential to develop hypertrophic scarring.

Etiological structure and antibiotic resistance pattern of burn wound infections in hospitalized patients - a one-center study in Varna, Bulgaria.

In the present retrospective study, we have evaluated bacterial pathogens isolated from patients admitted to the Burn Care Unit at the Military Medical Academy, Varna, Bulgaria over a three-year period (January 2019 - December 2021). We also tried to summarize the corresponding antibiotic resistance pattern of the isolated infectious agents. A total of 1030 isolates were obtained from 1912 burn wound samples investigated. There were 553 Gram-positive (53.7%) and 477 Gram-negative (46.3%) isolates. The most common isolates for the study period were coagulase-negative staphylococci (CoNS) (25%), Pseudomonas aeruginosa (17.7%), Staphylococcus aureus (16.6%), Acinetobacter baumannii (7.7%), Enterobacter spp. (7.1%), Escherichia coli (4.4%), Proteus spp. (3.4%), and Klebsiella spp. (2.9%). Glycopeptide antibiotics and linezolid were the most effective drugs against gram-positive isolates, followed by amikacin (for synergistic combinations), whereas colistin, imipenem, meropenem, cefoperazon/sulbactam, and piperacillin/tazobactam were the most active drugs against Gram-negative isolates, and colistin, ampicillin/sulbactam - against A. baumannii.

Prognostication of the development of septic complications in children with burn injuries.

OBJECTIVE: Aim: To determine the prognostic criteria for the development of septic complications in children with thermal injury. PATIENTS AND METHODS: Materials and Methods: A single-center retrospective-prospective cohort study included a retrospective analysis of 98 medical histories of children of different ages with severe burns who were treated from 2007 to 2017. A prospective study was conducted among children (n=63) from 1 to 5 years old, who received various degrees severity burn injury, according to an open comparative method in the period from 2018 to 2021. RESULTS: Results: Indicators of a high risk of developing sepsis were burns by flames of any etiology, damage severity index ≥75 units, total burn surface ≥25 %, deep burn area ≥ 5%. The threshold value of procalcitonin (PCT) ≥ 0.86 ng/ml on the 1st-3rd day and PCT > 0.51 ng/ml on the 7th day of burn disease, had a prognostic value for assessing the probability of sepsis. On the 1st day of hospitalization, the development of sepsis was predicted if the C-reactive protein (CRP) value was higher than 6.98 ng/ml, on the 3rd - the CRP level was above 7.43 ng/ml, on the 7th day - above 7.28 ng/ml. CONCLUSION: Conclusions: Based on the obtained data, we selected the criteria with the best prognostic characteristics, which allows us to predict and prevent the development of sepsis in the early stages of burn disease in children.

IL-8 Induces Neutrophil Extracellular Trap Formation in Severe Thermal Injury.

Neutrophil extracellular traps (NETs) have a dual role in the innate immune response to thermal injuries. NETs provide an early line of defence against infection. However, excessive NETosis can mediate the pathogenesis of immunothrombosis, disseminated intravascular coagulation (DIC) and multiple organ failure (MOF) in sepsis. Recent studies suggest that high interleukin-8 (IL-8) levels in intensive care unit (ICU) patients significantly contribute to excessive NET generation. This study aimed to determine whether IL-8 also mediates NET generation in patients with severe thermal injuries. IL-8 levels were measured in serum samples from thermally injured patients with ≥15% of the total body surface area (TBSA) and healthy controls (HC). Ex vivo NET generation was also investigated by treating isolated neutrophils with serum from thermal injured patients or normal serum with and without IL-8 and anti-IL-8 antibodies. IL-8 levels were significantly increased compared to HC on days 3 and 5 (p < 0.05) following thermal injury. IL-8 levels were also significantly increased at day 5 in septic versus non-septic patients (p < 0.001). IL-8 levels were also increased in patients who developed sepsis compared to HC at days 3, 5 and 7 (p < 0.001), day 10 (p < 0.05) and days 12 and 14 (p < 0.01). Serum containing either low, medium or high levels of IL-8 was shown to induce ex vivo NETosis in an IL-8-dependent manner. Furthermore, the inhibition of DNase activity in serum increased the NET-inducing activity of IL-8 in vitro by preventing NET degradation. IL-8 is a major contributor to NET formation in severe thermal injury and is increased in patients who develop sepsis. We confirmed that DNase is an important regulator of NET degradation but also a potential confounder within assays that measure serum-induced ex vivo NETosis.

Deciphering AKI in Burn Patients: Correlations between Clinical Clusters and Biomarkers.

Acute kidney injury (AKI) is a significant complication in burn patients, impacting outcomes substantially. This study explores the heterogeneity of AKI in burn patients by analyzing creatinine time-series data to identify distinct AKI clusters and evaluating routine biomarkers' predictive values. A retrospective cohort analysis was performed on 2608 adult burn patients admitted to Hangang Sacred Heart Hospital's Burn Intensive Care Unit (BICU) from July 2010 to December 2022. Patients were divided into four clusters based on creatinine trajectories, ranging from high-risk, severe cases to lower-risk, short-term care cases. Cluster A, characterized by high-risk, severe cases, showed the highest mortality and severity, with significant predictors being PT and TB. Cluster B, representing intermediate recovery cases, highlighted PT and albumin as useful predictors. Cluster C, a low-risk, high-resilience group, demonstrated predictive values for cystatin C and eGFR cys. Cluster D, comprising lower-risk, short-term care patients, indicated the importance of PT and lactate. Key biomarkers, including albumin, prothrombin time (PT), cystatin C, eGFR cys, and total bilirubin (TB), were identified as significant predictors of AKI development, varying across clusters. Diagnostic accuracy was assessed using area under the curve (AUC) metrics, reclassification metrics (NRI and IDI), and decision curve analysis. Cystatin C and eGFR cys consistently provided significant predictive value over creatinine, with AUC values significantly higher (p < 0.05) in each cluster. This study highlights the need for a tailored, biomarker-driven approach to AKI management in burn patients, advocating for the integration of diverse biomarkers in clinical practice to facilitate personalized treatment strategies. Future research should validate these biomarkers prospectively to confirm their clinical utility.

Demographic Study of Epileptic Burn Patient in a Tertiary Level Hospital of Bangladesh.

Burns are very common and important injuries associated with epilepsy. Epileptics are afflicted with burns when they come in contact with fire or other burning agents while seizing, due to loss of consciousness. The aim of the study was to identify the causes of burn, pattern and characteristics of burn in patients with epilepsy, duration of hospital stay and pattern of treatment in these patients. This prospective observational study was conducted in the Department of Burn and Plastic Surgery, Mymensingh Medical College Hospital, Bangladesh from January 2022 to December 2023. Epileptics were found in 0.84% (n=19) of the total admission (2274) in Burn unit. Majority of the patients were females (84.2%) and the mean age was (31.42±1.32) years. Maximum patients were housewives (78.9%). Among 19 cases, 11 cases (57.89%) had history of irregularly taking antiepileptic drugs and 8 cases (42.11%) had no history of treatment for epilepsy. Two cases (10.53%) had history of previous burn injury. Flame burn was the major etiology (89.5%). Mean total burn surface area (TBSA) was (6.94±4.12%). Most patients had full thickness burns (63.2%). Regarding distribution of burn, maximum involvement was in upper limb i.e. 68.21% cases. Surgical treatment was needed in the majority of the patients (68.5%). Mean hospital stay of these patients was (5.36±2.26) weeks. Epilepsy patients whose seizures are inadequately controlled are at increased risks of injury, especially burn. For prevention of burn, epilepsy should be treated properly.

Interventions for postburn pruritus.

BACKGROUND: Postburn pruritus (itch) is a common and distressing symptom experienced on healing or healed burn or donor site wounds. Topical, systemic, and physical treatments are available to control postburn pruritus; however, it remains unclear how effective these are. OBJECTIVES: To assess the effects of interventions for treating postburn pruritus in any care setting. SEARCH METHODS: In September 2022, we searched the Cochrane Wounds Specialised Register, the Cochrane Central Register of Controlled Trials (CENTRAL), Ovid MEDLINE (including In-Process & Other Non-Indexed Citations), Ovid Embase, and EBSCO CINAHL Plus. We also searched clinical trials registries and scanned references of relevant publications to identify eligible trials. There were no restrictions with respect to language, publication date, or study setting. SELECTION CRITERIA: Randomised controlled trials (RCTs) that enrolled people with postburn pruritus to compare an intervention for postburn pruritus with any other intervention, placebo or sham intervention, or no intervention. DATA COLLECTION AND ANALYSIS: We used the standard methodological procedures expected by Cochrane. We used GRADE to assess the certainty of the evidence. MAIN RESULTS: We included 25 RCTs assessing 21 interventions with 1166 randomised participants. These 21 interventions can be grouped into six categories: neuromodulatory agents (such as doxepin, gabapentin, pregabalin, ondansetron), topical therapies (such as CQ-01 hydrogel, silicone gel, enalapril ointment, Provase moisturiser, beeswax and herbal oil cream), physical modalities (such as massage therapy, therapeutic touch, extracorporeal shock wave therapy, enhanced education about silicone gel sheeting), laser scar revision (pulsed dye laser, pulsed high-intensity laser, fractional CO2 laser), electrical stimulation (transcutaneous electrical nerve stimulation, transcranial direct current stimulation), and other therapies (cetirizine/cimetidine combination, lemon balm tea). Most RCTs were conducted at academic hospitals and were at a high risk of performance, attrition, and detection bias. While 24 out of 25 included studies reported change in burn-related pruritus, secondary outcomes such as cost-effectiveness, pain, patient perception, wound healing, and participant health-related quality of life were not reported or were reported incompletely. Neuromodulatory agents versus antihistamines or placebo There is low-certainty evidence that doxepin cream may reduce burn-related pruritus compared with oral antihistamine (mean difference (MD) -2.60 on a 0 to 10 visual analogue scale (VAS), 95% confidence interval (CI) -3.79 to -1.42; 2 studies, 49 participants). A change of 2 points represents a minimal clinically important difference (MCID). Due to very low-certainty evidence, it is uncertain whether doxepin cream impacts the incidence of somnolence as an adverse event compared to oral antihistamine (risk ratio (RR) 0.64, 95% CI 0.32 to 1.25; 1 study, 24 participants). No data were reported on pain in the included study. There is low-certainty evidence that gabapentin may reduce burn-related pruritus compared with cetirizine (MD -2.40 VAS, 95% CI -4.14 to -0.66; 1 study, 40 participants). A change of 2 points represents a MCID. There is low-certainty evidence that gabapentin reduces the incidence of somnolence compared to cetirizine (RR 0.02, 95% CI 0.00 to 0.38; 1 study, 40 participants). No data were reported on pain in the included study. There is low-certainty evidence that pregabalin may result in a reduction in burn-related pruritus intensity compared with cetirizine with pheniramine maleate (MD -0.80 VAS, 95% CI -1.24 to -0.36; 1 study, 40 participants). A change of 2 points represents a MCID. There is low-certainty evidence that pregabalin reduces the incidence of somnolence compared to cetirizine (RR 0.04, 95% CI 0.00 to 0.69; 1 study, 40 participants). No data were reported on pain in the included study. There is moderate-certainty evidence that ondansetron probably results in a reduction in burn-related pruritus intensity compared with diphenhydramine (MD -0.76 on a 0 to 10 numeric analogue scale (NAS), 95% CI -1.50 to -0.02; 1 study, 38 participants). A change of 2 points represents a MCID. No data were reported on pain and adverse events in the included study. Topical therapies versus relevant comparators There is moderate-certainty evidence that enalapril ointment probably decreases mean burn-related pruritus compared with placebo control (MD -0.70 on a 0 to 4 scoring table for itching, 95% CI -1.04 to -0.36; 1 study, 60 participants). No data were reported on pain and adverse events in the included study. Physical modalities versus relevant comparators Compared with standard care, there is low-certainty evidence that massage may reduce burn-related pruritus (standardised mean difference (SMD) -0.86, 95% CI -1.45 to -0.27; 2 studies, 166 participants) and pain (SMD -1.32, 95% CI -1.66 to -0.98). These SMDs equate to a 4.60-point reduction in pruritus and a 3.74-point reduction in pain on a 10-point VAS. A change of 2 VAS points in itch represents a MCID. No data were reported on adverse events in the included studies. There is low-certainty evidence that extracorporeal shock wave therapy (ESWT) may reduce burn-related pruritus compared with sham stimulation (SMD -1.20, 95% CI -1.65 to -0.75; 2 studies, 91 participants). This equates to a 5.93-point reduction in pruritus on a 22-point 12-item Pruritus Severity Scale. There is low-certainty evidence that ESWT may reduce pain compared with sham stimulation (MD 2.96 on a 0 to 25 pressure pain threshold (PPT), 95% CI 1.76 to 4.16; 1 study, 45 participants). No data were reported on adverse events in the included studies. Laser scar revision versus untreated or placebo controls There is moderate-certainty evidence that pulsed high-intensity laser probably results in a reduction in burn-related pruritus intensity compared with placebo laser (MD -0.51 on a 0 to 1 Itch Severity Scale (ISS), 95% CI -0.64 to -0.38; 1 study, 49 participants). There is moderate-certainty evidence that pulsed high-intensity laser probably reduces pain compared with placebo laser (MD -3.23 VAS, 95% CI -5.41 to -1.05; 1 study, 49 participants). No data were reported on adverse events in the included studies. AUTHORS' CONCLUSIONS: There is moderate to low-certainty evidence on the effects of 21 interventions. Most studies were small and at a high risk of bias related to blinding and incomplete outcome data. Where there is moderate-certainty evidence, practitioners should consider the applicability of the evidence for their patients.

A deep dive into burn-mediated ARDS severity assessment: a retrospective study on hematological markers.

Acute Respiratory Distress Syndrome (ARDS) is a critical form of Acute Lung Injury (ALI), challenging clinical diagnosis and severity assessment. This study evaluates the potential utility of various hematological markers in burn-mediated ARDS, including Neutrophil-to-Lymphocyte Ratio (NLR), Mean Platelet Volume (MPV), MPV-to-Lymphocyte Ratio (MPVLR), Platelet count, and Platelet Distribution Width (PDW). Employing a retrospective analysis of data collected over 12 years, this study focuses on the relationship between these hematological markers and ARDS diagnosis and severity in hospitalized patients. The study establishes NLR as a reliable systemic inflammation marker associated with ARDS severity. Elevated MPV and MPVLR also emerged as significant markers correlating with adverse outcomes. These findings suggest these economical, routinely measured markers can enhance traditional clinical criteria, offering a more objective approach to ARDS diagnosis and severity assessment. Hematological markers such as NLR, MPV, MPVLR, Platelet count, and PDW could be invaluable in clinical settings for diagnosing and assessing ARDS severity. They offer a cost-effective, accessible means to improve diagnostic accuracy and patient stratification in ARDS. However, further prospective studies are necessary to confirm these findings and investigate their integration with other diagnostic tools in diverse clinical settings.

Multimodality management of locoregionally extensive Marjolin ulcer: a case report and review of the literature.

BACKGROUND: Marjolin ulcer (MU) is an aggressive cutaneous malignancy that commonly occurs in those with a chronic wound such as post-burn scar. CASE REPORT: A 20-year-old male who sustained a flame burn over the scalp at 3 months of age developed a nonhealing ulcer over the burn scar 20 years later, which was treated with adequate surgical margins with adjuvant mold brachytherapy. Two months after completion of that treatment, he developed parotid nodal metastasis with positron emission tomography (PET)-positive bilateral cervical, supraclavicular, right suboccipital, and mesenteric lymph nodes that were treated with concurrent chemoradiation. One month later, the patient developed an ulcerative lesion involving the left parotid region with PET showing infiltration of the parotid gland, but with resolution of other previous sites of uptake. The patient was treated surgically with radical parotidectomy with elective neck dissection and reconstruction with locoregional flap. At 6-month follow-up, the patient developed extensive locoregional recurrence and distant metastasis and was started on oral metronomic therapy. The patient was alive with stable disease at 3-month follow-up after initiation of palliative chemotherapy. CONCLUSION: Despite timely multimodality therapy, MU may present with a hostile clinical course with a short disease-free interval and early recurrence.

[Hydrogen sulfide balneotherapy in comprehensive sanatorium-resort treatment of post-burn scars in children]. / Serovodorodnaya bal'neoterapiya v kompleksnom sanatorno-kurortnom lechenii posleozhogovykh rubtsov u detei.

Thermal lesions in children leave behind cicatricial contractions, contractures, deformations of the wrists, feet, face. Sanatorium-resort treatment using balneotherapy is an integral part of rehabilitation measures in such patients. OBJECTIVE: To analyze the results of hydrogen sulfide balneotherapy in children with consequences of thermal injury. MATERIAL AND METHODS: A single-center observational retrospective non-controlled study was carried out, in which sanatorium-resort treatment concerning post-burn scars in 812 children aged 5-17 years was analyzed. Hydrogen sulfide balneotherapy was prescribed to patients depending on the age in mild (5-6 years) or moderate-to-high (7-17 years) exposure modes. The imported hydrogen sulfide mineral water from the T-2000 well of the Matsesta field with the H2S total concentration of 410-420 mg/l was used for treatment. The applications were performed to children alternate days, 8 procedures of balneotherapy per course. RESULTS: Lightening of the affected areas of the skin, reduction of the sensation of contraction and tension of the scars, which became softer, more elastic and more mobile with regard to the subjacent tissues have been noted in patients after the course of balneotherapy. The head mobility increased after applications in the presence of scars. The large joints' range of motion grew up. In addition, an increase in the mobility of the fingers of wrists and feet, a decrease in the stiffness of movements, increase or recovery of the affected skin's tactile sensitivity have been observed. Children well tolerated procedures, adverse events were seen in 0.7% of cases in the form of mild reactions at the beginning of the applications' course, namely of balneological (0.6%) and toxico-allergic (0.1%) nature. CONCLUSION: Hydrogen sulfide balneotherapy in combination with rehabilitation exercises and other sanatorium-resort factors is an effective mean of post-burn scars correction in children.

The impact and validity of the Berlin criteria on burn-induced ARDS: Examining mortality rates, and inhalation injury influences. A single center observational cohort study.

BACKGROUND: As several recent studies have shown low mortality rates in burn injury induced ARDS early (≤7 days) after the burn, the Berlin criteria for the ARDS diagnosis in this setting may be disputed. Related to this issue, the present study investigated the incidence, trajectory and risk factors of early Acute Respiratory Distress Syndrome (ARDS) and outcome in burn patients, as per the Berlin criteria, along with the concurrent prevalence and influence of inhalation injury, and ventilator-acquired pneumonia (VAP). METHODS: Over a 2.5-year period, burn patients with Total Burn Surface Area (TBSA) exceeding 10% admitted to a national burn center were included. The subgroup of interest comprised patients with more than 48 h of ventilatory support. This group was assessed for ARDS, inhalation injury, and VAP. RESULTS: Out of 292 admissions, 62 sustained burns > 10% TBSA. Of these, 28 (45%) underwent ventilatory support for over 48 h, almost all, 24 out of 28, meeting the criteria for ARDS early, within 7 days post-injury and with a PaO2/FiO2 (PF) ratio nadir at day 5. The mortality rate for this early ARDS group was under 10%, regardless of PF ratios (mean TBSA% 34,8%). Patients with concurrent inhalation injury and early ARDS showed significantly lower PF ratios (p < 0.001), and higher SOFA scores (p = 0.004) but without impact on mortality. Organ failure, indicated by SOFA scores, peaked early (day 3) and declined in the first week, mirroring PF ratio trends (p < 0.001). CONCLUSIONS: The low mortality associated with early ARDS in burn patients in this study challenges the Berlin criteria's for the early ARDS diagnosis, which for its validity relies on that higher mortality is linked to worsening PF ratios. The finding suggests alternative mechanisms, leading to the early ARDS diagnosis, such as the significant impact of inhalation injury on early PF ratios and organ failure, as seen in this study. The concurrence of early organ failure with declining PF ratios, supports, as expected, the hypothesis of trauma-induced inflammation/multi-organ failure mechanisms contributing to early ARDS. The study highlights the complexity in differentiating between the contributions of inhalation injury to early ARDS and the related organ dysfunction early in the burn care trajectory. The Berlin criteria for the ARDS diagnosis may not be fully applicable in the burn care setting, where the low mortality significantly deviates from that described in the original Berlin ARDS criteria publication but is as expected when considering the actual not very extensive burn injury sizes/Baux scores as in the present study.

The impact of inhalation injury on fluid resuscitation in major burn patients: a 10-year multicenter retrospective study.

BACKGROUND: It remains unclear whether additional fluid supplementation is necessary during the acute resuscitation period for patients with combined inhalational injury (INHI) under the guidance of the Third Military Medical University (TMMU) protocol. METHODS: A 10-year multicenter, retrospective cohort study, involved patients with burns ≥ 50% total burn surface area (TBSA) was conducted. The effect of INHI, INHI severity, and tracheotomy on the fluid management in burn patients was assessed. Cumulative fluid administration, cumulative urine output, and cumulative fluid retention within 72 h were collected and systematically analyzed. RESULTS: A total of 108 patients were included in the analysis, 85 with concomitant INHI and 23 with thermal burn alone. There was no significant difference in total fluid administration during the 72-h post-burn between the INHI and non-INHI groups. Although no difference in the urine output and fluid retention was shown in the first 24 h, the INHI group had a significantly lower cumulative urine output and a higher cumulative fluid retention in the 48-h and 72-h post-burn (all p < 0.05). In addition, patients with severe INHI exhibited a significantly elevated incidence of complications (Pneumonia, 47.0% vs. 11.8%, p = 0.012), (AKI, 23.5% vs. 2.9%, p = 0.037). For patients with combined INHI, neither the severity of INHI nor the presence of a tracheotomy had any significant influence on fluid management during the acute resuscitation period. CONCLUSIONS: Additional fluid administration may be unnecessary in major burn patients with INHI under the guidance of the TMMU protocol.

Correlation of risk factors with systemic inflammatory response syndrome in burn patients at the Burn Center of Dr Soetomo General Hospital, Surabaya, Indonesia.

INTRODUCTION: Systemic inflammatory response syndrome (SIRS) is the main cause of death in burns and is associated with high burn mortality rates. SIRS occurs when burns are in the subacute phase and is affected by several factors, such as host, trauma and management. The research was conducted at the Burn Center of Dr Soetomo General Hospital, Surabaya, Indonesia, using retrospective observational analytic research design. The aim of the study was to assess the correlation of risk factors which include age, extent of burns, cause of burns, inhalation trauma, history of hyperglycaemia, anaemia, hypoalbuminemia and ESBL infection with the incidence of SIRS. MATERIALS AND METHODS: The study is observational analytic research using a retrospective design and secondary data of all burn patients treated at the Burn Center of Dr Soetomo General Hospital, Surabaya, Indonesia from January 2018 to December 2019. RESULTS: A total of 163 burn patients were included. Among comorbidities found were inhalation trauma (39.3%), diabetes mellitus (2.5%), anaemia (14.7%), hypoalbuminemia (40.5%) and ESBL infection (1.2%). A total of 11 patients (6.7%) suffered from SIRS. The statistical analysis showed that anaemia (p=0.012), hypoalbuminemia (p=0.030) and the percentage of burns (p=0.001) were significantly correlated to the incidence of SIRS while age, sex, cause of burn injury, inhalation trauma, diabetes mellitus and ESBL infection have no significant correlation with SIRS. CONCLUSION: Burn surface area is the most influencing factor of SIRS incident. It is important to meticulously monitor patients with extensive burn areas for indications of SIRS. However, the sample size of this study was relatively small, and it used a retrospective approach, so a larger sample size and a prospective or cohort design method were recommended for further study.

Malignant melanoma arising in a burn scar.

Secondary malignancies are rare but devastating complications of longstanding burn scars. Squamous cell carcinoma is the most common, followed by basal cell carcinoma and melanomas. There are fewer than 50 total reported cases of malignant melanomas arising in burn scars. We report a case of malignant melanoma arising within a longstanding burn scar confirmed by histology, FISH, and PRAME staining to further characterize melanomas arising in burn scars and to illustrate the diagnostic challenges they present.

Update on Hypertrophic Scar Management in Burn Patients.

Hypertrophic scars arise from burn injuries because of persistent inflammation in the reticular dermis. Several risk factors promote this chronic inflammation. One is tension on the burn wound/scar due to surrounding skin tightness and bodily movements. High estrogen levels and hypertension are also important systemic risk factors. Thus, to prevent burn wounds from developing into hypertrophic scars, it is important to focus on quickly resolving the reticular dermal inflammation. If conservative treatments are not effective and the hypertrophic scar transitions to scar contracture, surgical methods such as Z-plasty, full-thickness skin grafting, and local flaps are often used.

Management of the Sequelae of Skin Grafting: Pruritis, Folliculitis, Pigmentation Changes, and More.

Scars commonly give rise to unpredictable, potentially irritating, cutaneous complications including pruritis, folliculitis, and pigment changes. These problems can be self-limiting and are prevalent in many burn cases, although their expression varies among individuals. A better understanding of the presentation, risk factors, and pathophysiology of these long-term sequelae allows for more comprehensive care of burn survivors.

Surgical Management of Chronic Neuropathic Burn Pain.

Burn-related chronic neuropathic pain can contribute to a decreased quality of life. When medical and pharmacologic therapies prove ineffective, patients should undergo evaluation for surgical intervention, consisting of a detailed physical examination and elective diagnostic nerve block, to identify an anatomic cause of pain. Based on symptoms and physical examination findings, particularly Tinel's sign, treatments can vary, including a trial of laser therapies, fat grafting, or nerve surgeries (nerve decompression, neuroma excision, targeted muscle reinnervation, regenerative peripheral nerve interfaces, and vascularized denervated muscle targets). It is essential to counsel patients to establish appropriate expectations prior to treatment with a multidisciplinary team.

Risk factors for in-hospital acquisition of carbapenem-resistant Enterobacterales in patients with severe burns.

BACKGROUND: Although patients with severe burns are prone to severe infections with antibiotic-resistant bacteria and inevitably have some risk factors for carbapenem-resistant Enterobacterales (CRE) acquisition, risk factors for CRE infection or colonization in these patients have not been investigated. AIM: To identify the independent risk factors for CRE acquisition in patients with severe burns. METHODS: Patients admitted to the burn intensive care unit (BICU) for acute burn care were categorized based on culture results during BICU care into the CRE group and non-CRE group, which included the carbapenem-susceptible Enterobacterales (CSE) and control groups. Clinical and microbiological factors were compared between the CRE and non-CRE groups, and between the CRE and CSE groups to identify independent risk factors for in-hospital CRE acquisition. FINDINGS: Among the included 489 patients, 101 (20.7%) and 388 (79.3%) patients were classified in the CRE and non-CRE groups, respectively. The non-CRE group included 91 (18.6%) and 297 (60.7%) patients in the CSE and control groups, respectively. In multivariate analysis between the CRE and non-CRE groups, exposure to other CRE-acquired patients (P = 0.018), abbreviated burn severity index score ≥9 (P = 0.012), and mechanical ventilation (P < 0.001) were associated with CRE acquisition. In multivariate analysis between the CRE and CSE groups, exposure to other CRE-acquired patients was associated with CRE acquisition (P = 0.048). CONCLUSION: Considering the limitation of controlling the burn severity in hospitalized patients, enhanced infection control measures for preventing in-hospital CRE transmission among patients with severe burns should be emphasized.
