Background
The healing process of burns includes coagulation, inflammation, and remodeling. Vascular endothelial growth factor (VEGF) is involved throughout this healing process. Stem cells from the platelet-rich plasma (PRP) with stromal vascular fraction (SVF) can increase concentrations of growth factors, including VEGF. This is expected to accelerate burn healing. The aim of this study was to determine the effect of a combination of PRP and SVF on VEGF levels in a rats model of deep dermal burn wound healing.
Materials and methods
This is an experimental research study in rats using a post-test control group design with 4 groups: A) control, B) Vaseline, C) topical PRP and SVF, and D) PRP and SVF injection. Burn wounds were induced according to the modified Guo method.
Results
In a rats model of deep dermal wound healing, topical Vaseline significantly increased serum VEGF compared to control. Topical application and injection of stem cells also significantly increased serum VEGF compared to control and Vaseline. The VEGF concentration was significantly higher following injection of PRP and SVF, suggesting that the injection route is more effective at increasing VEGF levels compared to the topical application of stem cells.
Conclusion
The combination of PRP and SVF, either by injection or topical application, can increase VEGF levels during the healing process from deep dermal burns.
Background: Diabetic foot ulcers are one of the leading causes of amputation in non-traumatic patients. This research aimed to investigate the correlation between the level of HDL cholesterol and the severity level of diabetic foot ulcer based on Wagner classification. The study conducted at Wahidin Sudirohusodo Hospital, Makassar, Indonesia.Methods: This is an observational study with the cross-sectional design. The data collected before and after the treatment. The change of the levels of HDL cholesterol and the severity level of the diabetic foot ulcer based on Wagner classification during the treatment were analyzed. Data analyzed using Spearman Correlation test, the paired t-test to assess the change in the levels of HDL cholesterol and the levels of severity of diabetic foot ulcer based on Wagner classification at the time admission and after the treatment. ANOVA test was used to observe the reduction significance of the severity of diabetic foot ulcer based on Wagner classification, and it was categorized as significant if p<0.05.Results: The results indicated that there is a correlation between the level of HDL cholesterol and the severity level of diabetic foot ulcer based on Wagner classification either at the early treatment with p-value = 0.003 (r = - 0.448) and the end of the treatment with p-value = 0.001(r = - 0.477). The lower of the level of cholesterol HDL, the higher was the severity level of the diabetic foot ulcer. Meanwhile, the correlation between the increase of the level of HDL cholesterol and the reduction of Wagner classification during the treatment was statistically insignificant with p-value = 0.100 (r = - 0.215).Conclusions: there was a correlation between elevated HDL cholesterol levels during treatment with Wagner classification decrease during treatment, the higher the HDL change, the higher the Wagner classification, but this was weak correlation and statistically insignificant.
Background. Soft tissue haemangiomas are non-malignant lesions; some optional management could be chosen. Sclerotherapy by the sclerosing agent has been used in the management of haemangiomas. Method. We performed intramucous embolization of haemangioma in three patients. The procedure was conducted under general anesthesia. The sclerosing agent used was an absolute alcohol 98% at a dose of 10ml, 5ml, and 2ml in each patient. After the procedure, they received analgesics and antibiotic therapy. One month after the sclerosing treatment, all patients underwent reconstruction surgery. Result. The evaluation was performed several days after the injection. The pain and tissue swelling occurs in the first week and gradually decreased each day until the second week. The final result was evaluated after the patient undergone reconstruction surgery. All patient's parent were satisfied. Conclusions. The intralesional sclerotherapy of haemangioma using absolute alcohol proved to be a safe, cheap and effective method to achieve preoperative devascularization of hemangiomas
INTRODUCTION: Anal traumas, such as blunt and penetrating injuries to the perineum, can disrupt the anal sphincter and cause considerable morbidity. Non-invasive anal trauma therapies have been widely developed, including growth factors administered as platelet-rich plasma (PRP) and stromal vascular fraction (SVFs) containing adipose[1]derived stem cells (ASCs) and limited growth factor. This study aimed to assess PRP and SVF effects on capillary histopathology in the anal trauma Wistar rat model. MATERIALS AND METHODS: This experimental study used a rat model. Rats were divided into three groups: Group A (n=12) was treated with PRP and SVFs; Group B (n=12) was treated with normal saline (placebo); Group C (n=4) was sacrificed on day 0 to obtain baseline capillary counts. Groups A and B were further divided into three subgroups, sacrificed on days 1, 7, and 14 post-treatment. RESULTS: Capillary counts significantly showed higher density between Groups A and B (p=0.037, analysis of variance). On day 7, there was a significant difference between Groups A and B (p=0.001). CONCLUSION: Mean capillary density significantly improved in anal trauma treated with a combination of PRP and SVFs compared to control. Our findings support the use of PRP and SVFs to aid recovery of patients with anal trauma.
