As queimaduras provocam efeitos físicos e psicológicos devastadores nos indivíduos, sobretudo em crianças e adolescentes, e podem modificar a qualidade de vida da pessoa. O objetivo foi analisar o impacto das cicatrizes por queimaduras em crianças menores de oito anos na interação com amigos, família e escola, na perspectiva dos pais. Estudo quantitativo de corte transversal realizado com os pais de crianças <8 anos de idade, vítimas de queimaduras e internadas em um Centro de Tratamento de Queimados no norte do Paraná e acompanhadas ambulatorialmente, de 2017 a 2020. A coleta de dados ocorreu por meio de dois instrumentos: caracterização sociodemográfica e clínica; e Brisbane Burn Scar Impact Profile. Realizou-se análise descritiva e teste Qui-quadrado utilizando-se o SPSS®. Participaram 34 pais cujas crianças sofreram queimaduras, sendo 52,9% de 1 a 3 anos de idade, 58,8% sexo masculino, 82,2% por agente etiológico térmico e a internação foi de 73,5% devido à Superfície Corpórea Queimada ≤20%. Após a alta os pais identificaram que as cicatrizes de queimaduras tinham "um pouco" e "pouco" impacto nas cicatrizes nas relações de amizade e na interação social. Para os pais, prevaleceu a resposta "nada" de impacto, seguido por "um pouco" e "muito" na escola, nas brincadeiras, nos jogos e nas atividades diárias. Quanto às reações emocionais e ao humor, a maior parte dos pais considerou "nada". Nesse sentido, os pais responderam às questões quanto à própria percepção sobre as atividades diárias do seu filho e, em geral, a cicatriz de queimadura não impactou na qualidade de vida da criança.
Burns cause devastating physical and psychological effects on individuals, especially children and adolescents, and can change a person's quality of life. The objective was to analyze the impact of burn scars in children under eight years of age in the interaction with friends, family and school, from the parents' perspective. Quantitative cross-sectional study carried out with the parents of children <8 years old who were victims of burns and admitted to a Burn Treatment Center in northern Paraná and monitored on an outpatient basis, from 2017 to 2020. Data collection occurred using two instruments: sociodemographic and clinical characterization; Brisbane Burn Scar Impact Profile. Descriptive analysis and Chi-square test were performed using SPSS®. 34 parents participated whose children suffered burns, 52.9% aged 1 to 3 years old, 58.8% male, 82.2% due to thermal etiological agent and 73.5% hospitalization was due to Burned Body Surface ≤ 20%. After discharge, the parents identified that the burn scars had "a little" and "little" impact on the scars in friendship relationships and social interaction. For parents, the answer "nothing" of impact prevailed, followed by "a little" and "a lot" in school, play, games and daily activities. As for emotional reactions and mood, most parents considered "nothing" that impacted the child with burn scars. In this sense, parents answered questions regarding their own perception of their child's daily activities and, in general, the burn scar did not impact the child's quality of life.

BACKGROUND:How to provide sufficient skin resources for scar plastic surgery and repair of extensive deep burn patients while avoiding the re-proliferation of scar tissue in the surgical area has always been an important topic in burn and wound repair research. OBJECTIVE:To observe the clinical application effects of artificial dermis combined with autologous scar epidermis in the repair of scar after extensive burns. METHODS:Retrospective analysis was performed on 73 patients with scar hyperplasia and contracture deformity after extensive burns in Bengbu Third People's Hospital Affiliated to Bengbu Medical College from January 2021 to January 2023.The patients were divided into three groups according to the treatment method:Group A(n=21,artificial dermis combined with autologous scar epidermis transplantation was used for treatment),group B(n=27,scar epidermis was transplanted after scar release in the functional site),and group C(n=25,functional site scar release after transplantation of thick skin treatment).Skin survival and infection at the receiving site,wound healing time at the receiving site and the donor site were recorded in the three groups.The scar status and functional recovery of the recipient area and donor area were evaluated by the Vancouver Scar Scale and activities of daily living. RESULTS AND CONCLUSION:(1)The skin infection rate was lower in group B than that in groups A and C(P<0.05).The survival grade was higher in group B than that in groups A and C(P<0.05).(2)The wound healing time at the receiving site was longer in group A than that in groups B and C(P<0.05).The wound healing time at the receiving site was longer in group C than that in group B(P<0.05).The wound healing time at the donor site was longer in group C than that in groups A and B(P<0.05).(3)Vancouver Scar Scale score was higher in group B than that in groups A and C at 12 months postoperatively(P<0.05).Vancouver Scar Scale score was higher in group C than that in groups A and B at 6 and 12 months postoperatively(P<0.05).The excellent grade of activities of daily living in groups A and C was significantly higher than that of group B at 12 months postoperatively(P<0.05).(4)The results showed that the application of artificial dermis combined with autologous scar epidermis composite transplantation in the treatment of scar contracture after extensive burn could not only achieve the same effect as that of intermediate-thickness skin,but also avoid postoperative scar re-hyperplasia at the donor site and shorten the time of complete wound healing at the donor site.Compared with scar epidermal transplantation,this treatment has obvious advantages.

Objective:To explore the clinical effect of composite skin transplantation combined with systemic rehabilitation in the treatment of extensive scar contracture deformity around the popliteal fossa in children after burns.Methods:A retrospective observational research method was adopted. Seventeen children with extensive scar contracture deformities around the popliteal fossa after burns who met the inclusion criteria and were admitted to the First Affiliated Hospital of Air Force Military Medical University from March 2018 to April 2022 were selected. Among them, there were 10 males and 7 females, aged 2-11 years, with scar contracture deformities lasting from 10 months to 9 years, all located around the popliteal fossa, 10 cases of right popliteal fossa, 5 cases of left popliteal fossa, 2 cases of bilateral popliteal fossa, scars around the popliteal fossa result in a knee joint extension angle of only 95° to 115°. The scar contracture during surgery was thoroughly released, joint mobility was restored, so as to form a secondary wound range of 10 cm×8 cm-20 cm×13 cm. In stage Ⅰ, after completely releasing the scar contracture, the wound was covered with negative pressure closure drainage (VSD) for 2-3 days. In stage Ⅱ, a large autologous blade thick scalp and allogeneic decellularized dermal matrix composite graft was performed to repair the wound around the popliteal fossa. After 8-10 days of surgery, the dressing was changed to check the survival of the skin graft. One week after the skin graft survived, a 12 month orderly knee joint function training was conducted under the guidance of a rehabilitation therapist. Postoperative sequential treatment with a combination of strong pulsed light and ultra pulsed carbon dioxide lattice laser for 5-7 courses of significant scar hyperplasia in the skin graft area and edges.Results:15 cases of pediatric patients had good skin graft survival; One patient developed a wound due to partial displacement of the transplanted autologous scalp, and one patient developed a plasma swelling under the limb graft, which was drained through an opening. Two patients underwent dressing changes for 3 weeks before the wound healed. After follow-up for 6 to 36 months, the elasticity and appearance of the skin graft were similar to those of a medium thickness skin graft. Children with knee joint contracture were able to fully extend to 180°, and knee joint function was significantly improved. There was no scar formation or hair loss in the donor skin area.Conclusions:The combination of composite skin transplantation and systematic rehabilitation has a good effect on the treatment of extensive scar contracture around the popliteal fossa in children after burns, avoiding the problem of scars left in the donor area due to autologous skin grafting.

Abstract This study was carried out to evaluate the effect of Glutamine, as a dipeptide or a free amino acid form, on the progression of burn injuries in rats. Thirty male Wistar rats were burned with a comb metal plate heated in boiling water (98 °C) for three minutes, creating four rectangular full-thickness burn areas separated by three unburned interspaces (zone of stasis) in both dorsum sides. The animals were randomized into three groups (n=10): saline solution (G1-Control) and treated groups that orally received Glutamine as dipeptide (G2-Dip) or free amino acid (G3-FreeAA). Two and seven days after burn injury, lesions were photographed for unburned interspaces necrosis evolution assessment. Seven days after injury, glutathione seric was measured and histopathological analysis was performed. By photographs, there was a significant reduction in necrosis progression in G3-Free-AA between days two and seven. Histopathological analysis at day 7 showed a significantly higher stasis zone without necrosis and a higher number of fibroblasts in G2-Dip and G3-FreeAA compared with G1-Control. Also, glutathione serum dosage was higher in G2-Dip. The plasmatic glutathione levels were higher in the G2-Dip than the G1-Control, and there was a trend to higher levels in G3-FreeAA. The reduction in histological lesions, greater production of fibroblasts, and greater amounts of glutathione may have benefited the evolution of burn necrosis, which showed greater preservation of interspaces.
Resumo Este estudo foi realizado para avaliar o efeito da Glutamina, como um dipeptídeo ou forma de aminoácido livre, na progressão de queimaduras em ratos. Trinta ratos Wistar machos foram queimados com um pente de metal aquecido em água fervente (98 °C) por três minutos, criando quatro áreas retangulares queimadas separadas por três interesespaços não queimados (zona de estase) em ambos os lados do dorso. Os animais foram randomizados em três grupos (n = 10): solução salina (G1-Controle) e grupos tratados que receberam glutamina via oral como dipeptídeo (G2-Dip) ou aminoácido livre (G3-FreeAA). Dois e sete dias após a queimadura, as lesões foram fotografadas para avaliação da evolução da necrose entre os espaços não queimados. Sete dias após a lesão, foi dosada a glutationa sérica e realizada análise histopatológica. Pelas fotografias, houve uma redução significativa na progressão da necrose no G3-Free-AA entre os dias dois e sete. A análise histopatológica no dia 7 mostrou uma zona de estase significativamente maior sem necrose e número mais elevado de fibroblastos em G2-Dip e G3-FreeAA em comparação com G1-Controle. Os níveis plasmáticos de glutationa foram maiores no G2-Dip em relação ao G1-Controle, e houve tendência a níveis mais elevados no G3-FreeAA. A redução das lesões histológicas, maior produção de fibroblastos, maior quantidade de glutationa podem ter beneficiado a evolução da necrose da queimadura, que mostrou maior preservação dos interespaços.

Objective:To compare the therapeutic effects of modified plantar skin grafting and thigh skin grafting on the deep burn wounds of the back and buttocks.Methods:A retrospective cohort study was conducted to analyze the clinical data of 30 patients with deep burn wounds on their back and buttocks who were admitted to the 910th Hospital of Joint Logistic Support Force of PLA from January 2021 to April 2023, including 26 males and 4 females, aged 21-72 years [(49.9±14.0)years]. The total burn size was 50%-97% of the total body surface area (TBSA), with the third-degree burn on the back and buttocks 6%-16% TBSA. The burn wounds on the back and buttocks were repaired using plantar skin grafts alone, thigh skin grafts alone or plantar skin grafts combined with the grafts from other body parts. The patients were grouped according to the skin graft donor sites and the times of harvesting skin grafts: there were 20 patients undergone plantar skin grafting including 10 patient with plantar skin graft harvested once (group of plantar skin graft harvested once) and 10 patients with plantar skin graft harvested twice or three times (group of plantar skin graft harvested more than once), and 10 patients undergone thigh skin grafting harvested once (group of thigh skin graft harvested once). The areas of plantar skin grafts harvested at the last time and the wound areas on the back and butts that could be repaired each time were calculated. After the last harvest, the thickness of the stratum corneum, 7-day survival rate of the skin grafts, proportion of 3-month residual wound area in the skin graft area, healing time of the donor sites, and 6-month Vancouver Scar Scale (VSS) scores of the donor sites in the group of plantar skin graft harvested once were compared with those in the group of thigh skin graft harvested once and the group of plantar skin graft harvested more than once. The appearance and texture of the skin graft, patients′ walking patterns and complications were observed at 6 months after the last skin harvest.Results:All the patients were followed up for 6-18 months [(7.8±1.6)months]. In the 20 patients with plantar skin grafts harvested, the areas of skin grafts harvested at the last time were 2.5%-4.5% TBSA [(3.4±0.6)% TBSA] and the wound areas that could be repaired each time were 3%-8% TBSA [(5.5±1.5)% TBSA]. After the last harvest, the thickness of the stratum corneum in the group of plantar skin graft harvested once was (190.4±8.9)μm, which was significantly thicker than that in the group of thigh skin graft harvested once [(50.0±6.6)μm] and that in the group of plantar skin graft harvested more than once [(166.8±21.9)μm] ( P<0.01); the 7-day survival rate of the skin grafts, proportion of 3-month residual wound area in the skin graft area, healing time of the donor sites, and 6-month VSS scores of the donor sites were (93.6±2.3)%, 2.0 (0.1, 3.5)%, (9.9±1.8)days and (1.7±0.7)points in the group of plantar skin graft harvested once, (78.0±6.6)%, 5.3 (4.0, 5.8)%, (14.0±1.4)days and (4.9±2.3)points in the group of thigh skin graft harvested once, and (93.4±2.6) %, 2.0 (0.1, 3.8)%, (10.0±1.2)days and (1.8±0.8)points in the group of plantar skin graft harvested more than once. The group of plantar skin graft harvested once showed a significant increase in the 7-day survival rate and a significant decrease in the proportion of 3-month residual wound area in the skin graft area, healing time of the donor sites, and 6-month VSS scores of the donor sites in comparison with the group of thigh skin graft harvested once ( P<0.05 or 0.01), while there were no significant differences in above mentioned indices between the group of plantar skin graft harvested once and the group of plantar skin graft harvested more than once ( P>0.05). At 6 months after the last skin harvest, the skin graft areas on the back and buttocks were flat, hard and firm and all the patients in the three groups could walk normally, with no complications such as severe itching, pain or folliculitis in the skin graft area. Conclusions:In the treatment of burn wounds on the back and buttocks, compared with thigh skin grafting, modified plantar skin grafting has advantages of thicker stratum corneum, better wear resistance and pressure resistance in the skin graft areas, a higher survival rate of skin grafts, rapid healing, mild scar, and undisturbed walking pattern after surgery and no common complications.

Objective:pH low insertion peptide (pHLIP)-variant 7 (var7)-fluorescein isothiocyanate (FITC) was used to explore an accurate imaging tool that targeted burn wounds to better perform burn debridement.Methods:Twelve rat models of burn wound were established and pHLIP-var7-FITC with different concentrations (0.5, 1.5 and 2.0 mg/ml) were injected from the rat tail vein for in vivo fluorescence imaging. By determining the concentration of fluorescent conjugates to the burn wound, the scope of wound injury necrosis was judged by combining pathological sections, and its residue and toxicity in important organs such as heart, liver, kidneys, and brain were detected. The Kruskal-Wallis rank sum test, Bonferroni correction method and one-way analysis of variance were used for data analysis. Results:Within 24 h, the fluorescence photons per unit area of the burn wound in the group of 0.5 mg/ml, 1.5 mg/ml and 2.0 mg/ml were 1.49(1.31, 1.65), 2.46(1.88, 2.68), 2.77 (1.94, 3.10)×10 7 p·s -1·cm -2·Sr -1, with significant differences in the overall distribution of fluorescence photons ( H=73.55, P<0.001). The fluorescence intensity was stronger in the group with higher concentration, but with no significant difference in the number of fluorescence photons between the group of 1.5 mg/ml and 2.0 mg/ml ( P=0.263, Bonferroni correction method). At 14 time points (0.5, 1.0, 1.5, 2.0, 2.5, 3.0, 3.5, 4.0, 5.0, 6.0, 7.0, 8.0, 12, 24 h), there was no significant difference in the overall mean of fluorescence photons ( F=1.04, P=0.419), and the tissue with burn necrosis seen in tissue sections was highly consistent with the fluorescence imaging region. There was no obvious fluorescence residue in the heart, liver, kidney and brain sections. Conclusion:In superficial second-degree burn tissue, pHLIP-var7-FITC can accurately target and gather on the burn wound within 24 h, showing a clear boundary between burn tissue and normal tissue, which can assist clinical surgical debridement to determine the extent of injury.

ABSTRACT Purpose: This study aimed to describe the demographic and clinical characteristics of victims of fireworkrelated ocular trauma treated at the ophthalmologic emergency de partments of two reference centers in Pernambuco, Brazil, and to identify risk factors related to poor visual prognosis. Methods: We retrospectively evaluated the medical records of patients admitted in emergency departments with a report of firework-related trauma between January 2012 and December 2018. Data collected included patient's age, sex, place of origin, month and year of the accident, ocular structures affected, characteristics of the injuries, and type of treatment that patients received. For patients who were followed for >30 days, the final visual acuity and patient's origin were analyzed. Results: Three hundred and seventy eyes from 314 patients were included, of which 248 (79.0%) were male and 160 (51.0%) were from the metropolitan region of Recife. The mean patient age was 25.6 ± 18.8 years. In 56 (17.8%) patients, the ocular trauma was bilateral. A total of 152 (48.4%) cases occurred in June. The most affected sites were the eyelids in 91 (24.6%) eyes and ocular surface in 252 (68.1%). Surgical treatment was required in 87 (23.5%) eyes. After clinical and surgical management, 37 (10.0%) eyes presented final visual acuity of <20/400. Of these, 34 (91.9%) eyes were from patients from the countryside or from another state. Patients from the countryside presented higher risk of developing blindness after a firework trauma than those from the metropolitan area (odds ratio of 5.46). Conclusions: Victims of firework-related ocular trauma were mostly male, from the metropolitan region of Pernambuco state and mainly pediatric patients or economically active. Those coming from the countryside and other states had higher risk of developing blindness

ABSTRACT Introduction: burns represent a pivotal component of trauma in Brazil, accounting for 2 million incidents and 2,500 deaths annually. Self-intentional burns are associated with a worse prognosis, larger burned surface area, higher infection rates, and death. The lack of studies on the issue of self-immolation raises epidemiological questions regarding Brazilian victims. This study aimed to investigate the profile of burn events associated with self-injurious behavior among Brazilian victims. Methods: this systematic review was performed according to PRISMA 2020 guidelines and evaluated the correlation between self-injurious behavior as a cause of burns in Brazilian victims and its epidemiological implications in the last 20 years (2003-2023). The MeSH terms "Burns", "Self-Injurious Behavior", "Epidemiology" and "Brazil" were queried in the PubMed/MEDLINE, SciELO, and Cochrane Library databases, and, after selection by inclusion/exclusion criteria, the most relevant studies were critically analyzed. Results: From 1,077 pre-selected studies, 92 were potentially eligible, resulting in 7 manuscripts incorporated in this review. From 3,510 burned victims assembled in the pool of selected studies, 311 cases displayed self-injurious behavior. Burned patients who attempted to burn their lives have a higher risk of death (p<0.05; RR=5.1 [3.2-8.1]) and larger burned surface area (p<0.05; MD=19.2 [10-28.2]), compared to accidental cases. Moreover, the female gender was at a higher risk of attempting self-immolation (p<0.05; RR=4.01 [2.9-5.5]). Conclusion: our results show that self-inflicted burn cases were associated with a larger burned surface area and a higher risk of death, and the female gender was identified as a relevant risk factor in Brazil.
RESUMO Introdução: Queimaduras representam um componente fundamental do trauma no Brasil, sendo responsáveis por 2 milhões de incidentes e 2.500 mortes anualmente. Queimaduras autointencionais estão associadas a pior prognóstico, maior superfície corporal queimada, maiores taxas de infecção e morte. A falta de estudos sobre a problemática da autoimolação levanta questões epidemiológicas em relação às vítimas brasileiras. O estudo se objetivou investigar o perfil das queimaduras associados ao comportamento autolesivo entre vítimas brasileiras. Métodos: Esta revisão sistemática foi realizada de acordo com as diretrizes PRISMA 2020 e avaliou a correlação entre comportamento autolesivo como causa de queimaduras em vítimas brasileiras e suas implicações epidemiológicas nos últimos 20 anos (2003-2023). Os termos MeSH "Burns", "Self-Injurious Behavior", "Epidemiology" e "Brazil" foram elencados no PubMed/MEDLINE, SciELO e Cochrane Library e, após seleção por critérios de inclusão/exclusão, os estudos mais relevantes foram analisados criticamente. Resultados: Dos 1.077 estudos pré-selecionados, 92 foram potencialmente elegíveis, resultando em 7 manuscritos incorporados nesta revisão. Das 3.510 vítimas queimadas reunidas no conjunto de estudos selecionados, 311 casos apresentaram comportamento autolesivo. Pacientes que tentaram autoimolação apresentam maior risco de morte (p<0,05; RR=5,1 [3,2-8,1]) e maior superfície corporal queimada (p<0,05; MD=19,2 [10-28,2]), em comparação com casos acidentais. Ademais, o sexo feminino apresentou maior risco para tentativa de autoimolação (p<0,05; RR=4,01 [2,9-5,5]). Conclusão: Nossos resultados mostram que os casos de queimaduras autoprovocadas foram associados a uma maior área de superfície corporal queimada e a um maior risco de morte, e o sexo feminino foi identificado como um fator de risco relevante no Brasil.

Abstract Objective: to evaluate the effect of photobiomodulation with low-level 660 nm laser alone or associated with Human Amniotic Membrane in the repair of partial-thickness burns in rats. Method: an experimental study conducted with 48 male Wistar rats, randomized into four groups: Control, Human Amniotic Membrane, Low-Level Laser Therapy, and Low-Level Laser Therapy associated with Human Amniotic Membrane. The histopathological characteristics of the skin samples were analyzed 7 and 14 days after the burn. The data obtained were submitted to the Kolmogorov-Smirnov and Mann-Whitney tests. Results: the histological analysis of the burn injuries showed a decrease in inflammation (p<0.0001) and an increase in proliferation of fibroblasts (p<0.0001) mainly at 7 days in all treatments related to the control group. At 14 days, the greater effectiveness in accelerating the healing process was significant (p<0.0001) in the Low-Level Laser Therapy group associated with the Human Amniotic Membrane. Conclusion: the association of photobiomodulation therapies with the Human Amniotic Membrane allowed verifying a reduction in the healing process time of the experimental lesions, stimulating its proposal as a treatment protocol in partial-thickness burns.
