Aggressive fluid resuscitation has been extensively discussed after the establishment of fluid creep phenomenon as a morbidity and mortality factor in burn children. Sepsis is currently the leading cause of death in survivors of burn shock. ⋯ Fluid creep, surgery procedures and length of stay in hospital parameters showed better results in burn children treated with early albumin. Fluid creep and length of stay in the hospital were associated with infection, providing a negative prognosis.

Early burn wound assessment is a major problem in pediatrics. It involves regular clinical evaluations, and may be helped by objective tools, such as thermal imagers. Because of the skin temperature difference between partial and full thickness burns, due to injured vascular perfusion of the dermis in the latter, it could precisely identify areas with superficial burns which could heal from controlled wound healing, and those with deep burns which would need skin graft, at an early stage. The objective of this study was to assess the validity of the Flir one thermal imager® for this purpose. ⋯ The Flir One Thermal Imager® is an inexpensive, non-invasive, and easy-to-use device. It measures indirectly but with an excellent specificity the dermis perfusion reflecting the burns depth in children. However its low sensitivity calls for additional research to allow skin grafts earlier in common practice and decrease the length of stay.

Thermal injury repair is a complex process during which maintaining the proliferation of human dermis fibroblasts (HDFs) and synthesis of extracellular matrix (ECM) plays a critical role. In the present study, we analyzed potential molecular markers and the probable association between differentially-expressed lncRNAs and protein-coding genes within denatured dermis following thermal injury, attempting to provide further insights to thermal injury repair pathogenesis. ⋯ In conclusion, mRNAs and lncRNAs could be differentially expressed in the denatured dermis following thermal injury. mRNA and lncRNA regulatory signaling pathways could participate in thermal injury repair pathogenesis. More importantly, LINC00302 may play a critical role in thermal injury repair.

Silver sulfadiazine (SSD) has been widely used in burned patients for the prevention of local infections. To be biologically active and exert antimicrobial properties, silver needs to be present in the form of silver ions (Ag1+) that bind to negatively charged proteins, namely, the RNA and DNA in microorganisms. However, previous published studies conducted with SSD in the 1990s reported a high level of silver absorption through damaged skin and noted the potential cytotoxicity of Ag1+ to human cells. SSD toxicity, however, had been described in cell cultures using arbitrary silver concentrations. In the present study, we determined the serum silver levels in burned patients treated with SSD and, taking into account the molar Ag1+ concentrations found in these patients, we evaluated the Ag1+ toxicity effects on inflammatory cells (ROS and cytokine production) in vitro. ⋯ These findings suggest that Ag1+ may contribute to negative outcomes after burns, decreasing the primary defense mechanism (respiratory burst) and altering cytokine production.

Observational Study
Characteristics and outcomes of patients with grill-related Burn injuries admitted to the Cologne Burn Center, Germany.
Grilling has become increasingly common in Germany. Although grilling is considered a non-negligible household burn hazard, few reports have assessed this type of injury. This study aimed to determine the patterns and characteristics of grill-related burn injuries and to compare these with other types of burn injuries. ⋯ Grill-related injuries are a relatively common cause of admission to the Cologne Burn Center. Although grill-related injuries underwent a less aggressive approach than the other investigated fire injuries, the former represent a public health concern because they mainly affect the upper body, with both psychologic and aesthetic consequences. We recommend a German nationwide multi-centric study of the patterns and characteristics of burn injury.
