  • A 1-year-old Korean domestic short-haired cat presented with skin hyperextensibility and a severely macerated wound on the skin of the dorsal part of the neck. Diagnostic studies including histopathology and skin extensibility index revealed congenital cutaneous asthenia (Ehlers-Danlos syndrome). In this cat, the skin wounds and defects were successfully managed with standard wound management and cosmetic surgery. Although skin hyperextensibility is persistent, the cat has lived well without other complications to date. To the best of our knowledge, this is the first report of cutaneous asthenia in a cat in Korea.

  • This study was under taken to investigate the healing of Sa Gun Ja Tang extract (SE) and Sa Gun Ja Tang added Radix Astragali extract (SHE) on the artificial wound on rabbit skin. The granulation tissues were observed by microscope at the five day interval for twenty days. In order to understand the healing mechanism chick embryo culture was carried out in the presence of the extracts and the growth ratio and fusion index were counted. The results obtained were as follows: 1. The healing power of SE treated group on wound was more significant than the control group. 2. The healing power on wound was more effective at the SHE than the SE. 3. The growth ratio and fusion index were higher at the SHE treated groups than the SE treated groups. From the above result, SHE was more effective than the SE on wound healing activity by the mechanism of stimulating the cell growth ratio and fusion index.

  • Background The free anterolateral thigh (ALT) flap has been widely used for various kinds of reconstructions. However, delayed healing at the donor site occasionally occurs due to wound dehiscence or the partial loss of grafted skin at the donor site. The aim of the present study was to identify reliable predictive factors for delayed healing at the donor site after the harvest of a free ALT flap. Methods This study included 52 patients who underwent reconstructive procedures using free ALT flaps. The delayed healing group included patients with wounds at the donor site that had not healed over 3 weeks after surgery, and the normal healing group included patients who showed wound healing within 3 weeks after surgery. Multivariate logistic regression models were created to identify the risk factors for delayed healing at the ALT flap donor site. Results Among the 52 patients, 24 (46.2%) showed delayed healing at the donor site, and 6 patients required additional operative treatment. A high preoperative body mass index (BMI), smoking, and skin grafting were found to be significantly associated with delayed healing at the ALT donor site. Of the 37 patients who underwent skin grafting, 23 (62%) experienced delayed healing at the donor site. Conclusions A high preoperative BMI, smoking, and skin grafting were risk factors for delayed healing at the free ALT donor site. Skin grafting at the ALT donor site should be avoided in patients with a high BMI or a habit of smoking.

  • Background: Antibiotic resistance is a significant public health concern around the globe. Antimicrobial peptides exhibit broad-spectrum and efficient antibacterial activity with an added advantage of low drug resistance. The higher water content and 3D network structure of the hydrogels are beneficial for maintaining antimicrobial peptide activity and help to prevent degradation. The antimicrobial peptide released from hydrogels also hasten the local wound healing by promoting epithelial tissue regeneration and granulation tissue formation. Objective: This study aimed at developing sodium alginate based hydrogel loaded with a novel antimicrobial peptide Chol-37(F34-R) and to investigate the characteristics in vitro and in vivo as an alternative antibacterial wound dressing to treat infectious wounds. Methods: Hydrogels were developed and optimized by varying the concentrations of crosslinkers and subjected to various characterization tests like cross-sectional morphology, swelling index, percent water contents, water retention ratio, drug release and antibacterial activity in vitro, and Pseudomonas aeruginosa infected wound mice model in vivo. Results: The results indicated that the hydrogel C proved superior in terms of cross-sectional morphology having uniformly sized interconnected pores, a good swelling index, with the capacity to retain a higher quantity of water. Furthermore, the optimized hydrogel has been found to exert a significant antimicrobial activity against bacteria and was also found to prevent bacterial infiltration into the wound site due to forming an impermeable barrier between the wound bed and external environment. The optimized hydrogel was found to significantly hasten skin regeneration in animal models when compared to other treatments in addition to strong inhibitory effect on the release of pro-inflammatory cytokines (interleukin-1β and tumor necrosis factor-α). Conclusions: Our results suggest that sodium alginate -based hydrogels loaded with Chol-37(F34-R) hold the potential to be used as an alternative to conventional antibiotics in treating infectious skin wounds.

  • An 87-year-old woman was referred for the extraction of residual teeth and removal of tori prior to prosthetic treatment. After surgery under general anesthesia, the surgical tape was removed to detach the bispectral index sensor and the hair cover. After the surgical tape was removed, skin injury occurred on the left side of her face. After epidermis repositioning and ointment application, a dressing was placed over the injury. Her wound was found to have healed completely on follow-up examination. Medical adhesive related skin injury (MARSI) is a complication that can occur after surgery and subjects at the extremes of age with fragile skin are at a higher risk for such injuries. Careful assessment of the risk factors associated with MARSI is an absolute necessity.

  • Background and Objectives For experiments on simulated burn, the preparation of an animal model is a very important step. The purpose of the current experiment is to design a simple and controllable method for the preparation of third-degree scald in a mouse model using the boiling water method. Materials and Methods A total of 18 Swiss mice were used. After the anesthetization, the mice were scalded by boiling water (100℃) using a mold with a 1 cm2 circle area on the dorsum at contact times of 3s, 5s, and 8s. After confirming that 8 seconds of scald can cause a third-degree scald, the skin samples were collected at day 2, 4, 6, 8, 10, and 12, and analyzed by histopathological examinations. The wound retraction index (WRI) was also measured. Results Third-degree scald involving full-thickness skin was observed in the 8-second scald group, while a 3-second scald caused a superficial second-degree scald and a 5-second scald caused a deep second-degree scald. After third-degree scald, the burn wound continued to contract until day 14. Conclusion The scalding model of mice can be successfully established by the boiling water method. This method is easy to operate, it has a low cost, and it can control the scald depth by controlling the scald time. This is adequate to study skin thermal injury in the future. The scald model established by this method can last for 14 days.

  • Purpose: Necrotizing fasciitis is a life-threatening, destructive soft tissue infection with a very high rate of mortality that needs early diagnosis and aggressive treatment. Systemic Lupus Erythematosus (SLE) is a systemic, autoimmune disease and it's major cause of mortality is an infection. But necrotizing fasciitis in SLE is very rare and there have been only 22 cases reported in the literatures. We reported a patient of necrotizing fasciitis with SLE and reviewed 22 others from literature research. Methods: A 40-year-old female patient with a history of SLE for 6 years came to the emergency room. The patient complained of severe pain and swelling on her right leg. She was diagnosed as necrotizing fasciitis and underwent emergency fasciotomy. As wound cultures showed variable organisms, she was treated with broad-spectrum antibiotics and underwent several surgical debridements. Then, the wound was treated with the V.A.C (Vacuum Assisted Closure) device and split thickness skin grafting was performed two times. Results: Skin graft was well taken within 2 weeks after operations and the patient was discharged to outpatient follow up. There was no complication related with surgery and she could walk without cane after 3 months. Conclusion: We treated a necrotizing fasciitis in a patient with SLE and reviewed 22 others from literature research. The case presented here suggests that necrotizing fasciitis is a rare disease in SLE patients, but should be considered in the differential diagnosis of soft tissue infection in SLE patients. A high index of suspicion is needed for early diagnosis and proper management in these patients.

  • Purpose: The purpose of this study was to develop an algorithm for preventing and managing of pressure ulcer and to verify the its appropriateness. Methods: The first step was development of a pre-algorithm through a literature review and expert opinion. The second step was to establish content validity by submitting the algorithm questionnaires about the content to 12 experts. The third step was the revision of the algorithm. The fourth and last step was to establish the clinical validity of the algorithm with 25 experienced nurses. Results: For the ease of the practitioner the algorithm for prevention and the management of pressure ulcers was confined to one page depicting the main algorithm pathway and seven stepwise guidelines. The guidelines included skin care of pressure ulcer prevention, mechanical loading care, support surface care, reposition care of pressure ulcer, and Stages II, III and IV explanations along with debridement/wound irrigation and infection control. Most of all algorithm courses chosen more than 80% of agreement by expert index of content validity. The usefulness, appropriateness, and convenience of the algorithm were demonstrated through clinical validity with intensive care unit and ward nurses. Conclusion: The algorithm will improve the quality of pressure ulcer nursing care as it provides a model for decision making for clinical nurses as well as providing consistent and integrated nursing care for patients with pressure ulcer throughout an institution.
