The effects of photobiomodulation using LED on the repair process of skin graft donor sites.

The benefits of photobiomodulation (PBM) applied to wounds are well-described in the literature; however, its effects in skin graft donor sites have been poorly studied. The aim of this study is to evaluate the effects of LED PBM on re-epithelialization and wound quality of the skin donor site and on pain during repair process. This is a case series study that part of the patients received standard treatment and the others received standard treatment combined with PBM. Data collection was performed at the Burn Unit at a Public Hospital, Brazil. The study had 21 participants and 25 donor sites, 13 in the control group (conventional treatment with Membracel® bandage) and 12 in the experimental group (Membracel® + LED). Irradiation parameters were 1.53 J/cm2, 2.55 mW/cm2, 660 nm, 600 s in the immediate postoperative period as well as on the 1st, 3rd, 5th, and 7th days postoperatively. Pain was measured using the visual analog scale. The Bates-Jensen scale was used to monitor the re-epithelialization process and measurements were performed of donor skin sites in the postoperative period. Quantitative variables were expressed as mean ± standard deviation or median and interquartile range [p25; p75]. The comparison of the distribution of these variables between groups was performed using the Mann-Whitney test. No differences between groups were found for re-epithelialization time, area or quality of the wound. Regarding pain, a significant reduction was found on the 5th postoperative day in the experimental group compared to the control group. PBM did not induce changes in the re-epithelialization period, wound area or wound quality scores of the Bates-Jensen Scale but did induce a reduction in pain compared to the group treated with Membracel® alone.

Perfil epidemiológico de pacientes queimados internados em centro de referência na cidade de São Paulo / Epidemiological profile of burning patients admitted to a reference center in the São Paulo city

OBJETIVO: Determinar o perfil epidemiológico de pacientes vítimas de queimaduras internados em um centro de tratamento de queimaduras da cidade de São Paulo. MÉTODO: Trata-se de um estudo transversal retrospectivo descritivo de abordagem quantitativa, baseado na análise dos prontuários físicos e do livro de registro do centro de tratamento de queimaduras de um hospital geral da zona norte da cidade de São Paulo, de janeiro de 2014 a dezembro de 2020. Os dados foram coletados por instrumento semiestruturado quanto a etiologia, sexo, faixa etária, classificação de grau de extensão e gravidade de queimaduras definida pelo Ministério da Saúde na Portaria Regulamentadora nº 1274, de 20 de novembro de 2000. RESULTADOS: A amostra foi de 892 pacientes, com 67% do sexo masculino. A faixa etária entre 16 e 59 anos correspondeu a 80,83%. Os agentes etiológicos mais frequentes foram fogo/inflamável, com 57,4%, seguido por escaldo em 26,23%. As queimaduras classificadas como "pequenas" corresponderam a 12,44%, as "médias" 34,42 % e as "grandes" 53,14%. CONCLUSÃO: O estudo demonstrou um perfil epidemiológico compatível com centros especializados em queimaduras, ressaltando a importância destes estudos para a definição e implantação de estratégias com principal foco na educação populacional, resultando na prevenção para a redução progressiva da prevalência das queimaduras.

OBJECTIVE: To determine the epidemiological profile of burn victim patients admitted to a burn treatment center in the São Paulo city. METHODS: This is a descriptive retrospective cross-sectional study with a quantitative approach, based on the analysis of the physical records and the record book of the burn treatment center at a general hospital in the northern part of the city of São Paulo, from January 2014 to December 2020. Data were collected using a semistructured instrument regarding etiology sex, age group, degree of corporal extent and severity classification of burns defined by the Ministry of Health through Regulatory Ordinance No. 1274 of November 20, 2000. RESULTS: The sample consisted of 892 patients, with 67% male. The age group between 16 and 59 years corresponded to 80.83%. The most frequent etiological agents were fire / flammable with 57.4%, followed by scald in 26.23%. Burns classified as "small" corresponded to 12.44%, "medium" 34.42% and "large" "53.14%. CONCLUSION: The study demonstrated an epidemiological profile compatible with specialized burn centers, emphasizing the importance of these studies for the definition and implementation of strategies with a main focus on population education, resulting in the prevention for progressive reduction in the prevalence of burns.

Perfil microbiológico e de resistência aos antimicrobianos dos pacientes internados na Unidade de Queimaduras do Hospital Geral "José Pangella" de Vila Penteado / Microbiological profile and antimicrobial resistance profile of patients admitted to the Burn Unit of Hospital Geral "José Pangella" in Vila Penteado, Brazil

Introdução: As queimaduras são responsáveis por cerca de 180.000 mortes por ano no mundo e cerca de 1.000.000 de acidentes, mais de 100.000 internações hospitalares e 2.500 mortes por ano no Brasil. Dentre as causas de morbidade e mortalidade do paciente queimado, destacam-se as infecções. O conhecimento do perfil microbiológico e o adequado tratamento dos casos de infecção impactam na diminuição nas taxas de morbimortalidade. O objetivo é analisar o perfil microbiológico e de resistência aos antimicrobianos dos pacientes internados na Unidade de Queimaduras do Hospital Geral "José Pangella" de Vila Penteado, durante o período de 2011 a 2018. Métodos: O estudo é retrospectivo e levantou todos os exames microbiológicos dos pacientes internados por queimaduras na Unidade de Queimaduras do Hospital Geral "José Pangella" de Vila Penteado, localizado na cidade de São Paulo, durante o período de janeiro de 2011 até o final de dezembro de 2018. Resultados: Foram isolados 495 microrganismos, sendo 436 bactérias (88,080%) e 59 fungos (11,919%). Entre as amostras analisadas, a maior prevalência foi do Staphylococcus sp., seguido por Pseudomonas sp. e Klebsiella sp., destacando-se, ainda, Candida sp. e Acinetobacter sp. Conclusão: O manuseio dos pacientes vítimas de queimaduras continua sendo um grande desafio para os centros de tratamento de queimaduras. Identificar os patógenos responsáveis pelas infecções dos pacientes pode acarretar em uma otimização do tratamento, com a escolha de um antibiótico eficaz, e, dessa forma, acarretar na redução da morbimortalidade desses pacientes, além de diminuir tempo de internação e custos utilizados de maneira significativa.

Introduction: Burns are responsible for about 180,000 deaths per year worldwide and about 1,000,000 accidents, more than 100,000 hospital admissions and 2,500 deaths per year in Brazil. Among the causes of morbidity and mortality of burn patients, infections stand out. Knowledge of the microbiological profile and appropriate treatment of infection cases impact on the decrease in morbidity and mortality rates. The Objetive is to analyze the microbiological profile and antimicrobial resistance profile of patients admitted to the Burn Unit of the General Hospital "José Pangella" of Vila Penteado from 2011 to 2018. Methods: This is a retrospective study and surveyed all microbiological examinations of patients hospitalized for burns at the "José Pangella" Burns Unit of Vila Penteado General Hospital, located in the city of São Paulo, from January 2011 until the end of December 2018. Results: 495 microorganisms were isolated, being 436 bacteria (88,080%) and 59 fungi (11,919%). Among the samples analyzed, the highest prevalence was Staphylococcus sp., followed by Pseudomonas sp., Klebsiella sp., Candida sp. and Acinetobacter sp. Conclusion: Handling burn patients remains a major challenge for burn treatment centers. Identifying the pathogens responsible for patients infections may result in optimal treatment, with an effective antibiotic choice and reducing the morbidity and mortality of these patients, as well as significantly reducing hospitalization time and costs.
