A Randomized Controlled Trial of Silver Sulfadiazine, Biafine, and Saline-soaked Gauze in the Treatment of Superficial Partial-thickness Burn Wounds in Pigs

Topical use of Jiawei Simiao Yongan Gao to prevent radiodermatitis in patients with head and neck cancer: A retrospective cohort study

Radiodermatitis is a common side effect of radiotherapy, but currently there is no standard treatment for its prevention. This study aimed to observe the effect of topical application of a paste based on traditional Chinese medicine, Jiawei Simiao Yongan Gao, on radiodermatitis caused by radiotherapy for patients with head and neck cancer.This was a retrospective cohort study of 40 patients with head and neck cancer evaluated during their radiotherapy. Of these, 20 patients were treated with Jiawei Simiao Yongan Gao on the irradiated skin from the beginning of radiotherapy (JSY group). The other 20 patients were given standard nursing (standard group). Acute skin reactions were classified according to the radiation-induced skin reaction assessment scale (RISRAS) and American radiation therapy oncology group (RTOG) acute toxicity grading criteria every 2 weeks, and adverse effects were recorded until the end of the radiotherapy.The two groups showed differences in severity of radiodermatitis. At 0 to 30 Gy, the skin reactions were similar in the two groups, while above 40 Gy the skin reactions were significantly lower grade in the JSY group (P < .05). At 0 to 20 Gy, there was no statistical significance (P > .05); but above 30 Gy they were lower in the JSY group (P < .05).Jiawei Simiao Yongan Gao effectively alleviated acute radiodermatitis caused by radiotherapy of head and neck cancer patients compared with standard nursing.

Assessment of microcirculatory influence on cellular morphology in human burn wound healing using reflectance-mode-confocal microscopy

Previous studies have assessed the effects of changes in microcirculation on wound healing; however, the influence of microcirculation on tissue histomorphology remains widely unknown. Reflectance-mode-confocal microscopy (RMCM) enables in vivo tissue observation on a cellular level. We present RMCM data evaluating the local microcirculation and assess the influence on histomorphology during burn healing. RMCM was performed in 12 patients (aged; 36.2+/-14.2 years, maximum-burn-extent: 4% total body surface area) at times 12, 36, and 72 hours after a superficial burn. The following parameters were assessed: quantitative blood-cell-flow (cbf), epidermal thickness (Emin), basal-layer thickness (tbl), and granular cell-size (Agran). Cbf was found to be 54+/-3.6 cells/minutes (control), increased to 91+/-3.6 cells/minutes (p<0.05) 12 hours postburn; decreased to 71+/-6.1 cells/minutes (p<0.05) (36 hours), and to 63+/-2.3 cells/minutes (p>0.05) 72 hours postburn. Emin was 43.74+/-3.87 mum (control), increased to 51.67+/-4.04 mum (p<0.05) 12 hours, decreased to 48.67+/-3.51 mum (p<0.05) 36 hours, and to 45.33+/-3.21 mum (p>0.05) at 72 hours postburn. Tbl was 14.17+/-0.6 mum (control), increased to 16.93+/-1.15 mum (p<0.05) 12 hours, decreased to 15.93+/-1.20 mum (p<0.05) 32 hours, and to 15.00+/-0.85 mum (p>0.05) 72 hours postburn. Agran was 718+/-56.20 mum(2) (control), increased to 901+/-66.02 mum(2) (p<0.05) 12 hours, decreased to 826+/-56.86 mum(2) 36 hours, and 766+/-65.06 mum(2) at 72 hours postburn. RMCM enables in vivo observation of wound microcirculation and allows direct assessment of vascular effects on cutaneous histomorphology during the healing course of superficial burns.
