摘要：Background and Aim: Natural topical products have been used to enhance wound healing, especially in immunocompromised animals. The aims of this study were to evaluate and to compare the effects of moist exposed burn ointment (MEBO) and honey on the healing of full-thickness skin wounds in immunocompromised dogs. Materials and Methods: The study was conducted using 12 adults, apparently healthy mongrel dogs. Immunosuppression was induced in six dogs by oral administration of prednisone (2 mg/kg) and azathioprine (2 mg/kg), once a day for 21 days. On each dog, a total of 9, 1.5 cm in diameter full-thickness skin circular wounds were created aseptically in the thoracolumbar area under general anesthesia using customized skin punch biopsy kit. In a random fashion, three wounds in each dog were treatment using MEBO (contains b-sitosterol, baicalin, and berberine as active ingredients in a base of beeswax and sesame oil), honey or no treatment (control), once per day for 21 days. Wounds were grossly evaluated once a day for signs of inflammation or infection. In addition, biopsy specimens and digital imaging data of each wound were obtained on days 7, 14, and 21 for histopathological evaluation of the healing process. Results: Wounds in immunocompromised dogs appeared to heal significantly in a slower fashion than in non-immunocompromised counterparts. Digital analysis data showed that MEBO-treated wounds expressed better epithelialization area, faster contraction, and smaller wound area percentage when compared with honey-treated wounds. Histopathological analysis showed significantly higher angiogenesis scores in MEBO-treated wounds when compared with other treatments. Conclusion: Results of this study showed that MEBO resulted in significant enhancement of wound healing in both healthy and immunocompromised dogs. However, when compared to honey, the wound healing effect of MEBO was superior to that of honey.

摘要：BACKGROUND Aplasia cutis congenita (ACC) in newborns is a condition in which congenital defects or hypoplasia is present in part of the epidermis, dermis and even subcutaneous tissue (including muscle and bones). First reported by Cordon in 1767, ACC is a rare disease with a low incidence of 1/100000 to 3/10000. Currently, there are 500 cases reported worldwide. ACC can be accompanied by other malformations. The onset mechanism of the disease remains unknown but is thought to be correlated to factors such as genetics, narrow uterus, foetal skin and amniotic membrane adhesion, use of teratogenic drugs in early pregnancy and viral infection. CASE SUMMARY In August 2018, we treated a newborn with ACC on the left lower limbs using a combination of ionic silver dressing and moist exposed burn ointment (MEBO) and achieved a satisfactory treatment outcome. The skin defects were observed on the external genitals and on areas from the left foot to 3/4 of the upper left side. Subcutaneous tissue and blood vessels were observed in the regions with skin defects. The following treatments were provided. First, the wound was rinsed with 0.9% sodium chloride solution followed by disinfection with povidone-iodine twice. And then MEBO was applied to the wound at a thickness of approximately 1 mm. After applying ionic silver dressing, the wound was covered with sterile gauze. The wound dressing was replaced every 2-3 d. At the 4-mo follow-up, the treatment outcome was satisfactory. There was minimal scar tissue formation, and limb function was not impaired. CONCLUSION The combination of ionic silver dressing and MEBO to ACC is helpful.

摘要：Topical treatment for facial burns, Review question, We reviewed the evidence about the effects of topical (applied to the surface of the skin) treatments for healing burn wounds on the face or neck. We wanted to find out which treatments were most effective at healing these wounds and improving the appearance of scars, which is a particularly important issue in relation to facial burn injuries. We also wanted to find out how topical treatments affected the risk of complications such as infection and pain, and how they impacted on peoples' quality of life., Background, Burn injuries are an important health problem, and a major global cause of disability and disfigurement in both adults and children. Women and children in low‐income countries are at particular risk. Burns pose particular problems when they occur on the head or neck. The face is central to a person's identity and plays a vital role in communication. Other basic functions such as hearing, smell and breathing may become affected as a direct result of a facial burn. Topical treatments such as (non) antimicrobial creams and skin substitutes, are most commonly used to treat facial burns. We wanted to compare the effectiveness of these treatments to evaluate their benefits and harms., Study characteristics, In December 2019, we searched for randomised controlled trials (RCTs) investigating topical treatments for facial burns. RCTs are medical studies where the treatment or care people receive is chosen at random. This type of study design provides the most reliable health evidence about whether different approaches to treatment or care can make a difference. We found 12 studies that were suitable for inclusion in this review update, with 507 participants with mean ages ranging from 5.3 to 41.9 years. Three studies compared antimicrobials with non‐antimicrobials agents, two studies compared different antimicrobials, four studies compared skin substitutes with antimicrobials, while four studies compared a variety of topical treatments. One study contributed to two comparisons. Eight studies were small (fewer than 40 participants) and almost all studies were at high risk of bias due to lack of blinding (where participants and evaluators may have known which group the participants were allocated to and interpreted effects differently)., Key results, Overall, there is mainly low to very low‐certainty evidence on the effects of any topical intervention on wound healing or infection in people with facial burns. In addition, there is low to very low‐certainty evidence on the effects of the included interventions on need for surgery, pain, scar quality, patient satisfaction, length of hospital stay and side effects., All results were at high risk of bias and varied, which may have exaggerated the effects., Certainty of the evidence, Overall, the certainty of the evidence about the effectiveness of topical treatments for facial burns is low to very low. There is insufficient reliable evidence as to whether topical treatments improve outcomes for people with facial burns including improving wound healing, or rates of infection. Better trial design and reporting of these studies is required to contribute to evidence‐based burn care., How up to date is this review?, We searched for studies that had been published up to December 2019.

摘要：BACKGROUND: Thermal tissue injury is partly mediated by reactive oxygen metabolites. Oxygen free radicals are contributory to local tissue damage following thermal injury and accordingly an interventional therapy using antioxidants may be beneficial. Copper nicotinate complex can scavenge reactive oxygen species (i.e., has antioxidant activity). OBJECTIVES: To examine time-related morphological and biochemical changes following skin thermal injury and their modulation by copper nicotinate complex. MATERIALS AND METHODS: An animal model composed of 80 albino rats was established. Ten rats (nonburn group) served as a control group. Seventy rats (burn group) were anesthetized, given a 10% total body surface area, full-thickness burn. Ten rats (from the postburn group) were sacrificed after 24 h (without treatment, i.e., untreated-burn group). The remaining rats were divided into three subgroups (20 rats, each) and were treated topically either with soft paraffin, moist exposed burn ointment (MEBO, a standard therapeutic treatment for burns), or copper nicotinate complex. Five animals from each subgroup were sacrificed every week over a period of 4 weeks. The morphological and biochemical changes were evaluated and compared among the different groups. RESULTS: High levels of the plasma and skin nitiric oxide (marker of oxidative stress) were observed in the untreated-burn group. These levels were significantly low following the application of copper nicotinate complex. Low levels of plasma and skin superoxide dismutase (marker of oxidative stress) and plasma ceruloplasmin were observed in the untreated-burn group. These levels were significantly high following copper nicotinate complex treatment. The total and differential leukocyte counts were low following the onset of the thermal injury. They gradually returned to normal levels over a 4-week period following the application of MEBO or copper nicotinate complex. Compared to untreated-burn group, postburn-healing changes (resolution of the inflammatory reaction, reepithelization of the epidermis, angiogenesis, deposition of collagen fibers, and recovery of the subcellualr organelles) were significantly accelerated following the application of either MEBO or copper nicotinate complex. CONCLUSIONS: Application of copper nicotinate complex was associated with improved healing of the thermal burns of the skin. The underlying molecular changes underlying these effects await further investigations.
