Observational Study
Colistin monotherapy versus colistin-based combination therapy for treatment of bacteremia in burn patients due to carbapenem-resistant gram negative bacteria.
Carbapenem-resistant gram negative pathogen (CR-GNP) infection in burn patients is a growing concern since treatment options are limited and resistance to the main line of treatment, colistin, is increasing. The goal of this study was to compare treatment outcomes of colistin monotherapy versus colistin-based combination therapy for CR-GNP bacteremia in burn patients. A retrospective observational study was conducted between 2014 and 2017 in Hangang Sacred Heart Hospital located in Seoul, South Korea. ⋯ We found that eradication rate within 7 days and 30-day mortality rate were not significantly different between the two groups (71.9% versus 75.0%, P = 0.752 and 31.2% versus 38.5%, P = 0.503). In the Cox regression analysis, Charlson's comorbidity index, renal replacement therapy before colistin use, and duration of antibiotics were associated with 30-day mortality (HR, 1.23; 95% CI, 1.02-1.49; P = 0.030, HR, 2.28; 95% CI, 1.05-4.94; P = 0.037 and HR, 0.94; 95% CI, 0.89-0.99, P = 0.042, respectively). Colistin-based combination therapy did not show significant differences with regard to microbiologic and clinical outcomes compared with colistin monotherapy.

Lactate and lactate clearance in critically burned patients: usefulness and limitations as a resuscitation guide and as a prognostic factor.
Lactate levels to guide resuscitation in critically burned patients are controversial. The purpose of our study was to determine whether absolute lactate values or lower lactate clearance predict mortality, and whether these are useful tools in the resuscitation phase. ⋯ Initial elevated lactate levels are a factor of poor prognosis and the cut-off point that best predicts mortality should be adjusted in the patients with TBSA burned < 20%. The global clearance of lactate in the first 24 h, unlike what occurs in other injuries, does not correlate with mortality. Monitoring lactate can ensure adequate peripheral perfusion during resuscitation with lower than normal fluid preload values.

Compression garments are well accepted as routine practice for scar management after burn. In a recent systematic review, six main reasons for compression garment non-adherence were identified including sensory disturbances. To further understand the impact of sensory issues, the aim of the present study is to investigate associations between sensory variables and compression garment wear. ⋯ Overall, sensory factors assessed using both self-report and quantitative sensory testing were associated with compression garment adherence. This knowledge suggests the value in developing and evaluating sensory-informed treatment strategies to improve compression garment wear.

The current evidence to support the use of massage for scar management is conflicting in the literature. The purpose of this study was to compare two scar massage protocols administered with pediatric burn survivors to determine if a more structured and standardized approach to scar massage could improve outcome. A retrospective review of the medical records of 100 children who received massage during the time period when two different protocols were implemented was conducted and data that was collected as part of the clinical exam regarding scar height, vascularity, pliability, itch and pain were extracted. ⋯ However, when comparing patients who received Protocol A to those who received Protocol B, there was no difference found in scar height, vascularity, pliability, itch or pain. Using commonly applied subjective scar assessment tools, we did not find clinically meaningful changes in scar characteristics with the implementation of a structured scar massage program compared to a general approach to massage. Further research is needed to better define the impact of massage on the recovery experience for burn survivors.

This study aims to evaluate the effects of topical sole and co-administration of Platelet-rich plasma (PRP) and chitosan on the infected burn wounds model by Candida albicans in Wistar rats. A circle partial thickness contact burn wound model occurred via brass a size of 8mm diameter between the shoulders and after that, 50μl of a suspension containing C. albicans yeast (5×107) colony forming unit was poured on the surface of the wound. The experimental groups included Control, Clotrimazole, PRP and Chitosan+PRP that received any agent, Clotrimazole®, PRP and Chitosan+PRP to treat the wound, respectively. ⋯ Immunohistochemical results for HSP 70, HSP 90 and PCNA showed positive reactions and increased intensity in all the treated groups comparing to the control group. Activities of GPx and SOD were higher and the level of MDA was lower all treated groups compared to the control group. A topical use of PRP and chitosan can be advantageous in the infected burn wounds healing.
