A realistic model is very useful in laying the foundation for clinical treatment and further study of high-voltage electrical burns. We therefore established a soft-tissue-injury model of high-voltage electrical burn in rabbits using the highest voltage alternating current reported. Twenty-five healthy big-ear white rabbits were randomly divided into five groups (five in each group): control group (C group) before injury and 0.5-h, 24-h, 48-h and 72-h groups after injury. ⋯ Moreover, pathological changes were found in vital organs distal to the electric shock sites, such as the heart, liver, lung and kidney, indicating systemic injuries. The level of serum myocardial enzymes was significantly elevated, especially 24h after injury. Thus, electric shock at 3000 V output electric voltage for 0.1s can cause severe, focal, soft-tissue injury and pathological changes in the vital organs such as heart, liver, kidney and lung with the characteristics similar to those of high-voltage-electrical-burn patients.

Previous critical care and cardiology studies find that critically ill patients have worse outcomes when admitted to the hospital during off-hours as compared to those admitted during weekdays. As severe burn is equally emergent we hypothesized that this disparity in outcomes would exist for burn patients as well. ⋯ Contrary to studies in other critically ill patient populations, off-hours admission is not predictive of worse outcomes in burn patients.

Little published evidence is available regarding the recovery of patients with minor burns. Poor attendance at review clinics results in incomplete data which hampers accurate analysis of patient recovery. It is often assumed that non-attendance for review is due to full recovery and the inconvenience associated with clinic attendance. This study aimed to obtain final outcomes for a group of minor burn patients and identify factors contributing to missing data. ⋯ Minor burn patients with upper limb involvement recover well and intensive review of these patients is unnecessary.

Silver dressings are an integral part of the management of burn patients. Package inserts assert a lack of compatibility and safety with magnetic resonance imaging (MRI) and recommend removal prior to any MRI procedure, although there is no clear evidence to support this recommendation. Dressing removal is associated with increased pain, anxiety, stress, and analgesia use. This study was to determine whether these products produce MRI image distortion or if the agitation of the silver particles generates enough heat which might produce further skin damage. ⋯ Our data suggests silver containing wound dressings do not cause a significant increase in dressing temperature or image distortion and thus their removal is not warranted for clinical MRI examinations.

Randomized Controlled Trial Comparative Study
Comparison of efficacy of silicone gel, silicone gel sheeting, and topical onion extract including heparin and allantoin for the treatment of postburn hypertrophic scars.
We compared the efficacy of silicone gel (Scarfade), silicone gel sheet (Epi-Derm), and topical onion extract including heparin and allantoin (Contractubex) for the treatment of hypertrophic scars. Forty-five postburn scars were included in the study. Patients with scars less than 6 months from injury were assigned at random to three groups each containing 15 scars, and their treatment was continued for 6 months. ⋯ The difference between Scarfade group and Epi-Derm group was not significant; however, the differences of the other groups (Scarfade-Contractubex, Epiderm-Contractubex) were significant. Silicone products, either in gel or sheet, are superior to Contractubex in the treatment of the hypertrophic scar. The therapist should select the most appropriate agent according to the patient's need and guidelines of these signs.
