  • The wound healing process can be categorized as follows : inflammation, fibroplasia, neovascularization, collagen deposition, epithelialization, and wound contraction. During the healing process, various growth factors are secreted to accelerate wound healing. Previous studies have demonstrated that endogenous growth factors, such as vascular endothelial growth factor(VEGF) are the important regulatory polypeptides for coordinating the healing process. They are released from macrophages, fibroblasts, and keratinocytes at the site of injury and participate in the regulation of reepithelization, granulation tissue formation, collagen synthesis and neovascularization. Onchung-Um has been used clinically to treat various skin diseases. In addition, Onchung-Um has been also used for congestive inflammations. In the present study, we evaluated the effects of Onchung-Um on wound healing process and wound size reduction in rats. Full-thickness skin wounds ($15mm\;{\times}\;15mm$) were created on the back of rats. Rats were then divided into 2 groups : The Onchung-Um treated group that was orally administered with a dose of 193.9mg/100g of Onchung-Um extract per day for 15 days and Control group without Onchung-Um administration. Moreover, the histological changes and VEGF immunoexpressions of two groups were estimated. In results, wound closures were significantly accelerated by oral administration of Onchung-Um extract. Furthermore, in Onchung-Um treated group, there were significant increases in fibroblast migration, epithelialization compared with the Control group. VEGF expressions were also increased in Onchung-Um treated group. This study has therefore demonstrated the Onchung-Um can significantly improve the quality of wound healing and scar formation and the oral administration of Onchung-Um extract may increase early tissue angiogenesis in the incisional wound of an experimental animal model.

  • Purpose: Pemphigus vulgaris, a rare autoimmune blistering disease of the skin and mucous membranes remains a challenging disease to treat. Management is focused on immunotherapy against autoimmune antibodies that target keratinocyte cell adhesion molecules, and antibiotics preventing secondary infections. There is no established dressing protocol and skin is usually manipulated the least amount possible in order to minimize irritation. The authors suggest that early initiation of aggressive bathing and debridement of skin lesions, with nutritional support, is essential in accelerating resolution. Methods: A 40 year-old male previously diagnosed with pemphigus vulgaris was admitted due to exacerbation of mucocutaneous lesions involving the epidermis and mucosa of the whole body. Steroids, immunosuppressants, intravenous immunoglobulin and antibiotics were administrated, but infection and de-epithelialization progressed, while his general condition deteriorated with a weight loss of over 20 kilograms. The plastic surgery department intervened with daily bathing, debridement of unhealthy debris and non-traumatizing coverage of growing epithelium. Total parenteral nutrition and mobilization with rehabilitation therapy was initiated as early as possible. Results: After bathing, healthy epithelium gradually covered the patient's entire body, while his general condition improved with a corresponding weight gain of 14 kgs. Conclusion: Treatment of pemphigus vulgaris focuses on immunotherapy and infection control. However, an equal amount of attention should be laid on early intervention with daily dressings including bathing and irrigation, nutritional support, and exercise as this accelerates resolution of existing infections, promotes healthy epithelialization and leads to faster recovery.

  • Background There are currently no guidelines for the postoperative wound management of the hard-palate donor site in cases involving mucosal harvesting. This study describes our experiences with the use of an artificial dermis for early epithelialization and transparent plate fixation in cases involving hard-palate mucosal harvesting. Methods A transparent palatal plate was custom-fabricated using a thermoplastic resin board. After mucosal harvesting, an alginic acid-containing wound dressing (Sorbsan) was applied to the donor site, which was then covered with the plate. After confirming hemostasis, the dressing was changed to artificial dermis a few days later, and the plate was fixed to the artificial dermis. The size of the mucosal defect ranged from 8×25 to 20×40 mm. Results Plate fixation was adequate, with no postoperative slippage or infection of the artificial dermis. There was no pain at the harvest site, but a slight sense of incongruity during eating was reported. Although the fabrication and application of the palatal plate required extra steps before and after harvesting, the combination of the artificial dermis and palatal plate was found to be very useful for protecting the mucosal harvest site, and resulted in decreased pain and earlier epithelialization. Conclusions The combination of artificial dermis and a transparent palatal plate for wound management at the hard-palate mucosal donor site resolved some of the limitations of conventional methods.

  • Purpose: Pain management in burn treatment is important in improving wound healing and quality of life. Ibuprofen is a proven pain relieving agent in patients with partial thickness burn by intraveous injection. The purpose of this study is to evaluate the efficacy of Biatain Ibu® (polyurethane foam containing ibuprofen) in pain control for outpatients with partial thickness burns. Methods: A prospective randomized clinical trial was performed in outpatients with partial thickness burn from August 1, 2017 to July 31, 2018. Acute pain, chronic pain, complications, days for re-epithelialization and patient's satisfaction were compared between Biatain Ibu® and Biatain® groups. Results: A total of 20 patients (Biatain Ibu®, n=10; Biatain®, n=10) were assessed in the trial. On Burn days 3, 5, 7, 11, 13, and 15, the acute pain levels were significantly lower in the Biatain Ibu® group than in the Biatain® group. Complications, chronic pain levels and days for re-epithelialization were not significantly different between the two groups. Patient's satisfaction was not statistically significant but was higher in the Biatain Ibu® group. Conclusion: Biatain Ibu® is effective in relieving pain in outpatients with partial thickness burn without decreasing patient satisfaction, wound healing ability or developing any complications.

  • Mucoepidermoid carcinoma (MEC) is the most common type of malignant neoplasm in the minor salivary gland. The hard palate is a frequently involved site of MEC. The treatment of low-grade MEC on the hard palate is wide local resection with a tumor-free margin. In the present case, the maxillary defect was reconstructed using a buccal fat pad (BFP) flap, followed by application of 4-hexylresorcinol (4HR) ointment for 2 weeks. The grafted BFP successfully covered the tumor resection defect without tension and demonstrated complete re-epithelialization without any complications.

  • The oriental ore minerals, which mainly consisted of talc, actinolite, sericite, and halloysite were developed, and then used to examine the healing effect on the skin wound in rats. Full-thickness square wounds were formed on the backs of rats after the hairs on the dorsal surface were shaved. The ore minerals were applied to examine the healing effect from day 0 to 15 after wounding. Notable wound healings in terms of congestion around the wound, wound contraction and epithelialization were found in ore mineral-treated groups. Moreover, microscopic results revealed the formation of epithelial layer, hair follicles and progressive angiogenesis in ore mineral-treated groups, while complete epithelial layer could not be found in the control. These results suggest that ore minerals from Korean indigenous ores may have wound healing effect on the skin injury in rats.

  • We present the case of a patient with severe postoperative scarring from surgical treatment for gastroschisis, with the intestine located immediately under the dermal scar. Although many patients are unsatisfied with the results of scar repair treatment, few reports exist regarding severe or difficult cases involving the surgical repair of postoperative scar contracture. We achieved an excellent result via simulation involving graph paper drawings that were generated using computed tomography images as a reference, followed by dermal scar deepithelialization. The strategy described here may be useful for other cases of severe postoperative scar contracture after primary surgery for gastroschisis.

  • Many congenital and acquired defects occur in the maxillofacial area. The buccal fat pad flap (BFP) is a simple and reliable flap for the treatment of many of these defects because of its rich blood supply and location, which is close to the location of various intraoral defects. In this article, we have reviewed BFP and the associated anatomical background, surgical techniques, and clinical applications. The surgical procedure is simple and has shown a high success rate in various clinical applications (approximately 90%), including the closure of oroantral fistula, correction of congenital defect, treatment of jaw bone necrosis, and reconstruction of tumor defects. The control of etiologic factors, size of defect, anatomical location of defect, and general condition of patient could influence the prognosis after grafting. In conclusion, BFP is a reliable flap that can be applied to various clinical situations.

  • The aim of this case report is to present a case of 68-year-old male with a history of multiple myeloma and the intravenous use of Zometa (zoledronic acid) who had developed medication-related osteonecrosis of the jaw (MRONJ) following a hot pizza burn to the palate. Clinical and radiographic findings revealed grade 1 MRONJ of the right side of the hard palate. Soft tissue trauma and delayed epithelialization may be associated with some cases of MRONJ. Patients on anti-resorptive medications or anti-angiogenic drugs should be informed of the risk of bone exposure and subsequent MRONJ secondary to physical/chemical insults to the bone and soft tissue in the oral cavity.

  • The mammalian skin contains hair follicles, which are epidermal appendages that undergo periodic cycles and exhibit mini-organ features, such as discrete stem cell compartments and different cellular components. Wound-induced hair follicle neogenesis (WIHN) is the remarkable ability to regenerate hair follicles after large-scale wounding and occurs in several adult mammals. WIHN is comparable to embryonic hair follicle development in its processes. Researchers are beginning to identify the stem cells that, in response to wounding, develop into neogenic hair follicles, as well as to understand the functions of immune cells, mesenchymal cells, and several signaling pathways that are essential for this process. WIHN represents a promising therapeutic approach to the reprogramming of cellular states for promoting hair follicle regeneration and preventing scar formation. In the scope of this review, we investigate the contribution of several cell types and molecular mechanisms to WIHN.
