Skin is an ectodermal derivative that maintains internal homeostasis of the body. Any damage to the skin like burn injury internal homeostasis is lost, resulting in delayed healing. The aim is to study the histoarchitecture comparative effect of silver nitrate gel, and BMSCs (DDP) on third-degree burns in Wistar rats. A burn wound of size 2.5 cm (length) x 2.5 cm (breadth) x 6 mm (depth) was created using a preheated metal plate on flanks of Wistar rat. Every burn wound was treated with silver nitrate gel (commercially available as silverex), bone marrow differentiated dermal precursors, and monitored for 1, 7, 14, 21 days until wound healing. Wound surface area was measured and compared among groups with histological and gross observations. The healing time was faster in bone marrow differentiated dermal precursors (DDP) group compared to control. Prolonged silver nitrate gel usage heals burn wound with no infection, but silver toxicity was noted. Wound contraction is slower but steady using bone marrow differentiated dermal precursors (DDP) cell when compared to the group treated with silver nitrate gel. The data from this study help use to use bone marrow differentiated dermal precursors (DDP) cells as an alternate and effective way to treat burn wounds.

Burn Wound Healing

Burn wound healing involves a series of complex processes which are subject to intensive investigations to improve the outcomes, in particular, the healing time and the quality of the scar. Burn injuries, especially severe ones, are proving to have devastating effects on the affected patients. Stem cells have been recently applied in the field to promote superior healing of the wounds. Not only have stem cells been shown to promote better and faster healing of the burn wounds, but also they have decreased the inflammation levels with less scar progression and fibrosis. This review aims to highlight the beneficial therapeutic effect of stem cells in burn wound healing and to discuss the involved pathways and signaling molecules. The review covers various types of burn wound healing like skin and corneal burns, along with the alternative recent therapies being studied in the field of burn wound healing. The current reflection of the attitudes of people regarding the use of stem cells in burn wound healing is also stated.

The Relationship

[Formula: see text] Increased burn wound healing time has been shown to influence abnormal scarring. This study hypothesised that scar severity increases commensurate to the increase in time to healing (TTH) of the wound. Wound healing and scar data from burn patients treated by the Burn Service of Western Australia at Royal Perth Hospital were examined. The relationship between TTH and scar severity, as assessed by the modified Vancouver Scar Scale (mVSS), was modelled using regression analysis. Interaction terms evaluated the effect of surgery and total body surface area – burn (TBSA) on the main relationship. Maximum likelihood estimation was used to account for potential bias from missing independent variable data. The sample had a median age of 34 years, TTH of 24 days, TBSA of 3% and length of stay of five days, 70% were men and 71% had burn surgery. For each additional day of TTH, the mVSS score increased by 0.11 points ( P ≤ 0.001) per day in the first 21 days and 0.02 points per day thereafter ( P = 0.004). The relationship remained stable in spite of TBSA or surgical intervention. Investigation of the effect of missing data revealed the primary model underestimated the strength of the association. An increase in TTH within 21 days of injury is associated with an increase in mVSS or reduced scar quality. The results confirm that efforts should be directed toward healing burn wounds as early as possible.

PURPOSE: Evaluation of the rheological, biological and therapeutic properties of a new topical formulation consisting of chitosan gel containing 1% silver sulfadiazine, as an alternative for the treatment of burn wounds. METHODS: An experimental study was done with 21 Wistar rats divided into three groups. Group I was treated with chitosan gel without the antimicrobial, group II was treated with chitosan gel with 1% silver sulfadiazine and group III was treated with commercially available 1% silver sulfadiazine cream. RESULTS: Due to its pseudoplastic characteristic and good bioadhesiveness, the chitosan gels showed a satisfactory retention time over the wounds. No statistical difference was found in the amount of drug released from the chitosan gel and commercially available cream, as well as in the healing time among the groups. Wounds treated with chitosan gel with silver sulfadiazine showed a higher fibroblast production and a better angiogenesis than in the other groups, which are important parameters on the evolution of the healing process. CONCLUSION: The topical use of chitosan gel in association with silver sulfadiazine ameliorated the neovascularization and inflammatory reaction in burn wounds. This new formulation showed advantageous rheological properties and efficient release of the drug.

Childbirth is a natural process, but sometimes labor can also cause birth canaltrauma, especially in the aluminum region, this trauma can be injuries to the periniumarea, the cause can be intentional biases such as episiotomy or unintentional actions such as spontaneous tears in the process of removing the baby. Injury to the perineum if not treated properly can cause postpartum infection because the wound area will be a medium for developing germs. The purpose of this study was to analyze the effect of the use of breast milk in the treatment of periniem wounds with the duration of perinium wound healing at the Ramlah Parjib Clinic in Samarinda. The method used in this study was Posttest Only Control Group Desigen research subjects were postpartum motherswith a sample of 60 respondents taken by random sampling and grouped based on treatment using ASI. Data analysis using ANOVA test. The results showed that the use of ASI had a significant effect on the treatment of periniem wounds with a healing time seen from the P value of 0,000. Conclusion: Periniuem wound care techniques are factors that influence the duration of perinieum wound healing

Background: The development and pathogenetic substantiation of the new agents used for local therapy of thermal trauma (TT) is an urgent problem in medicine. Melatonin (MT) is an endogenous factor of homeostasis regulation with pleiotropic potential. The aim of our study was to assess the morphology, expression of matrix metalloproteinase-9 (MMP-9) and vascular endothelial growth factor (VEGF), indicators of repair, oxidative destruction of lipids in the skin lesion focus in the dynamics of experimental TT under the conditions of using the original dermal film (DF) with MT. Methods and Results: The experiment was performed on 104 male Wistar rats weighing 200-240 g. For modeling TT II degree according to ICD-10 a relative area of 3.5% of the body surface, an interscapular region isolated from the surrounding tissues, was immersed in distilled water at 98-99 °C for 12 sec. DF based on sodium carboxymethylcellulose with an area of 12 cm2 with MT at a concentration of 5 mg/g was applied daily for five days. The wound area and epithelialization rate were calculated. The content of MMP-9 and VEGF in the burn wound was assessed by an immunohistochemical method. In the homogenate of the burn wound, the content of LPO products was assessed. Morphological and biochemical studies were performed on Days 5, 10 and 20 after TT induction. With experimental TT from Day 5 to Day 20, the absolute area of the burn wound decreases by 35%, the rate of epithelialization increases, the number of neutrophils in the focus of thermal damage decreases, while the representation of lymphocytes, histiocytes, and fibroblasts increases; the expression of MMP-9 and VEGF increases; predominantly secondary and final LPO products in the heptane phase accumulate, the final products of LPO in the isopropanol phase of the lipid extract. The use of MT in the composition of DF daily for 5 days with experimental TT leads to a decrease in the area of the wound defect (by 46% of the original area on Day 20), an increase in the rate of its epithelialization, an increase in the content of lymphocytes and fibroblasts in the burn wound on Days 5, 10 and 20 of TT, a decrease in the representation of neutrophils and macrophages on Days 5 and 10, as well as an increase in VEGF expression on Days 5 and 10, MMP-9 - on Day 5 and a decrease in MMP-9 expression on Days 10 and 20 of TT. In addition, the use of MT in the composition of DF leads to a decrease in the content of predominantly secondary and end products of LPO in the heptane and isopropanol phases of the burn wound on Days 10 and 20 of TT. Correlation analysis revealed that a decrease in the burn surface area under a local application of MT occurs with an increase in the content of VEGF in the wound area and a decrease in the content of MMP-9 and secondary and final LPO products in the heptane phase and the isopropanol phase. On Day 20, there were direct moderate correlations between the absolute burn surface area, on one hand, and secondary and final LPO products, on the other, in the heptane phase (R=0.51, R=0,68; P<0.05) and the isopropanol phase (R=0.44, R=0.46; P<0.05), respectively. Conclusion: The results obtained expand the existing understanding of the role of changes in the expression of MMP-9 and VEGF in the pathogenesis of TT. We believe that the repair-stimulating effect of MT in the DF, which we established during TT at the preclinical stage, is associated with the LPO-limiting effect of MT and a change in the expression of MMP-9 and VEGF in the burn wound and is a prerequisite for further study of the mechanism of action and the effectiveness of MT application in clinical conditions in TT.

Burns are serious life-threatening health problems. This study was performed to determine the effect of educated platelets on burn wound healing process. 28 female wistar albino 200-220 gr rats were randomly divided into four groups. Group A1 rats(n:7) were the first-line burnt group from which blood samples are extracted to develop platelet-rich plasma(PRP) with the educated platelets that have a response to burn injury. Group B1 rats(n:7) were the unburnt group with ordinary platelets. Group A2 rats(n:8) were the second-line burnt group which was given PRP with educated platelets. Group B2 rats(n:6), as control group, were the second-line burnt group which was given PRP with ordinary platelets. Photos of rats' dorsum were taken by digital camera on the first day and 21st day of the study. Wound healing was determined by scar surface area. In the study group (Group A2) mean wound area was  53±37 mm², in the control group (Group B2) mean wound area was 114±55 mm² on the last day of the experiment. The sizes of the wounded areas were significantly lower in the study group compared with the control group (p: 0.039). Educated platelets seem to facilitate the recovery period of burn wound healing in rats.

Background: The final aim of burn management is to prevent infection, to promote early epithelialization as well as healing of wound and betterment of functional and asthetic after effects. The present study aimed to compare the effect of nano crystalline silver gel and silver sulfadiazine cream on the healing of second-degree burn wounds.Methods: After matching the inclusion and exclusion criteriaburn wounds of patients were divided into two parts (sides); one part was dressed with silver sulfadiazine cream and the other one was dressed with nano crystalline silver gel. The wound dressing was changed everyday after washing the wound with normal saline. Wound parameters were measured on the ninth day and twenth day of dressing, using clinical assessment and photographic tool. The obtained data were statistically analyzed using the Chi-square test.Results: In our study, most patients were noted to have increased epithelization, increased granulation tissue, decreased inflammation, decreased wound infection as well as decreased slough following dressing with both nanocrystalline silver gel and silver sulfadiazine cream but there were more in numbers of patients dressing with nanocrystalline silver gel.Conclusions: The effect of nanocrystalline silver gel on the reduction of the healing time and necrotic tissue amount and increasing the granulation, epithelialization, and necrotic tissue type was greater. Considering the above findings nanocrystalline silver gel is more recommended to be used for burn wounds.

Chronic wounds are a challenge for clinicians. Treating chronic wounds in elderly patients is difficult due to comorbidities and poor immunity, tissue renewal, and regeneration. This study shared the therapeutic experiences of 40 patients with super long-term difficult-to-heal wounds and to describe the effects of negative pressure wound therapy (NPWT)-assisted debridement and autologous scalp grafting. Elderly patients with chronic wounds for more than 60 years who underwent NPWT-assisted debridement and autologous scalp grafting between 2015 and 2017 were retrospectively analyzed. Forty patients were identified and analyzed. Among all patients, the average wound area was 56 (interquartile range 30-90) cm2. The wound infection rate was 82.1%, and that before the first autologous scalp grafting was 51.3%. The average total number of surgeries was 3, and the number of times the NPWT device was replaced was once. A total of 97.4% of patients had one autologous scalp grafting performed. The transplanted scalp survived completely in 97.4% of patients. One hundred percent of patients had no postoperative complications and healed. The average wound healing time was 34.5 ± 10.1 days. This study showed that NPWT-assisted debridement and autologous scalp grafting have the advantages of high survival rate of the skin and decreased wound recurrence and may be a suitable treatment for super long-term difficult-to-heal wounds in elderly patients.
