BACKGROUND: Burn injuries trigger complex immune responses and gene expression changes, impacting wound healing and systemic inflammation. Understanding these changes is crucial for identifying biomarkers and therapeutic targets. METHODS: We analyzed two gene expression omnibus datasets (wound tissue [GSE8056] and blood [GSE37069]) to identify differentially expressed genes (DEGs) in burn injury samples versus controls. Immune cell proportions were assessed using CIBERSORT. Functional enrichment analyses (Gene Ontology and Kyoto Encyclopedia of Genes and Genomes) and protein-protein interaction networks were constructed to identify key genes and pathways. RESULTS: We identified 1170 upregulated and 1227 downregulated DEGs. Gene Ontology analysis revealed enrichment in neutrophil activation, inflammatory response, and extracellular matrix organization. Kyoto Encyclopedia of Genes and Genomes analysis highlighted cytokine-cytokine receptor interaction, TNF, and IL-17 signaling pathways. Immune infiltration analysis showed significant changes in neutrophils, macrophages (M1/M2), and T-cell subsets. Protein-protein interaction network analysis identified five hub genes: JUN, STAT1, Bcl2, MMP9, and TLR2. CONCLUSIONS: This study provides a comprehensive bioinformatic analysis of gene expression and immune responses in burn injuries. The identified DEGs, hub genes, and pathways offer insights into the immune response mechanisms and suggest potential targets for diagnostic and therapeutic interventions in burn injury management.
Comprehensive management of acute neck burns is directed towards a satisfactory aesthetic and functional result. Primary microsurgical burn reconstruction of the anterior neck may offer advantages over the traditional technique of skin grafting and delayed reconstruction. It can be indicated in selected patients, obtaining good aesthetic results, with earlier functional recovery and reducing the number of surgical procedures required.
Burns in neonates have been reported following the use of pulse oximeters, various electrodes, chemical disinfecting agents and phototherapy blankets. Burn injuries in premature neonates are very rare and there have been no reports on major full skin thickness injuries. This case reports on preterm neonate male twins delivered at a Community Hospital. After the delivery they were placed on water warmers for 15-20 min and then transported into incubators. Burn injuries were noticed 1h after the delivery. Infant One, weight 1500 g, had an injury of 20% TBSA on his dorsum, waist and buttocks. The other infant, weight 1835 g, had an injury of 14% TBSA on the same areas. The infants were transported to the University Hospital. At the seventh day after the injury they recovered from respiratory distress and surgical procedures started. The eschar was excised deep to fascia and wounds were grafted with 0.1mm thickness skin grafts harvested from the thigh and cut into islets. Autografts were protected by overlay with fresh allograft harvested from the twins' father. Surgery procedures were performed in two steps, each second day, not exceeding 10% of total body area during excision. Donor sites healed at the eighth day after the surgery. Burn wounds healed gradually by way of spontaneous replacement of allograft and wound closure by spontaneous epithelization from the autograft islets. Eighteen days after the surgery all the grafted wounds were found epithelized. We conclude that in premature neonates relatively low temperatures may cause deep burn injuries. We recommend the delivery of preterm childbirths at well equipped facilities with staff qualified in nursing of premature neonates.
