  • Diabetic ulcer is usually seen in people with uncontrolled blood sugar. Reportedly, many factors such as impaired glucose metabolism, and macrovascular and microvascular diseases caused angiogenesis disorders and delayed the healing of diabetic ulcers, thus affecting the body's metabolism, nutrition, and immune function. This study aimed to explore the effect of paeonol on skin wound healing in diabetic rats and the related mechanism. A rat model of diabetic ulcer was established. High glucose-treated mouse skin fibroblasts were co-cultured with M1 or M2-polarized macrophages treated with or without paeonol. H&E and Masson staining were used to reveal inflammatory cell infiltration and collagen deposition, respectively. Immunohistochemistry visualized the expression of Ki67, CD31, and vascular endothelial growth factor (VEGF). Western blot was used to detect interleukin (IL)-1β, tumor necrosis factor (TNF)-α, IL-4, IL-10, CD31, VEGFA, and collagen I/III. The expression of iNOS and arginase 1 was revealed by immunofluorescence staining. Paeonol treatment augmented collagen deposition and the expression of Ki67, CD31, VEGF, and macrophage M2 polarization markers (IL-4 and IL-10) and reduced wound area, inflammatory cell infiltration, and macrophage M1 polarization markers (IL-1β and TNF-α) in the ulcerated area. In vitro, paeonol treatment promoted M2-polarization and repressed M1-polarization in macrophages, thereby improving the repair of cell damage induced by high glucose. Paeonol accelerates the healing of diabetic ulcers by promoting M2 macrophage polarization and inhibiting M1 macrophage polarization.

  • Objectives : The purpose of this study is to report on the treatment of wound dressing in patients with diabetic foot ulcers in the dermatology clinic of Korean medicine. Methods : First, sufficient marginal resection of the ulcer and necrotic tissue on the foot of a patient with diabetic peripheral neuropathy was performed. Inflammation was treated with Anti-inflammatory pharmacopuncture solution, and dressings were applied for one month using Cornu Cervi Parvum pharmacopuncture solution, and Haeboo ointment for granulation tissue formation and skin regeneration. Results : After 10 days of the treatment, the formation of new granulation tissue was observed in the necrotic tissue area, and the extent of the lesion decreased sharply from the 14th day. On the 40th day, epithelialization progressed so that the treatment was terminated, and complete keratinization of the site was observed at follow-up 3 weeks after the end of the treatment. Conclusions : In the treatment of wound dressings in diabetic foot ulcer patients, marginal resection treatment with the application of pharmacopuncture solution and herbal ointment showed good effect.

  • Purpose : This study was performed to evaluate the effects of a prolonged a $30^{\circ}$ side-lying position on comfort and skin condition by applying the trunk maintenance repositioning method, which can keep the $30^{\circ}$ side-lying position effective for preventing pressure ulcers. Method : Fifty-four healthy nurses working at a general hospital in Seoul were randomly assigned to an experimental group (n=27) or a control group (n=27) and assumed a position of lying on their right or left side for two hours. The trunk maintenance repositioning method was applied to the experimental group using the pillow made by the researcher, while the original repositioning method was applied to the control group using the regular pillow from the subject hospital. Participants' posture angles, comfort, and skin condition were measured at the time of the intervention, as well as at one and two hours after the intervention. Results : There was no statistically significant difference in position angle, comfort, skin condition change, or sacrum and greater trochanter pressure change between the two groups over time. Conclusion : It is necessary to review the method and frequency of change of position in each hospital. In addition, a proper position changing pillow should be developed in consideration of patients' various body shapes.

  • Objectives This paper was aimed to review experimantal and clinical articles on Yeoldahanso-tang(YDHS), figuring out the recent tendency and suggesting the future prospects of YDHS-related studies. Methods The articles published in Korean or English since 2000 were searched, screened, and classified into experimental or clinical studies. And we structured designs, methods and results of the included studies into each table for the experimental studies or the clinical studies. Especially tools to diagnose constitutions and patterns identified in clinical researches were also summarized in the tables. Results 28 articles are finally included. 14 experimental studies are mostly in vitro designs to show efficacy of YDHS. There are only 2 studies for the safety. Among 14 clinical studies, 12 case studies target disorders of central nervous system, viral infection, skin ulcer and so on. 2 studies are before and after studies on cerebral infarction and effects on liver function. Conclusions Based on the efficacy of YDHS on central nervous system, it acquires higher level of evidence such as randomized controlled trials in the future. In addition other diseases such as skin ulcer and so on, it needs to be done more specific experimental or clinical studies so that we can get statistically significant results.

  • Purpose: Malignant changes of Marjolin's ulcer arising from chronic burn scar are rare. The majority of them are squamous cell carcinoma and basal cell carcinoma. Malignant fibrous histiocytoma is a deep seated pleomorphic sarcoma, which occurs principally as a mass of the extremities, abdominal cavity, or retroperitoneum in adults. Methods: We report a 58-year-old male patient who was admitted due to $3.5{\times}5cm$ chronic ulceration of anterior chest wall on the center of old burn scar. His scar had been occurred by boiling oil and treated with conservative treatment 45 years ago. Preoperative punch biopsy showed suspicious malignant changes and contrast enhanced chest CT showed well-defined, irregular shape enhancing lesion on anterior chest wall without intrathoracic metastasis. Results: The tumor was widely excised and defect was covered with skin graft without infection, necrosis and any other complication. The pathologic findings are compatible with malignant fibrous histiocytoma(storiform - pleomorphic type). The patient underwent 3 cycles of chemotheraphy. Although distant metastasis to the lung developed 6 months later and the patient died 9 month later, there was no local reoccurrence. Conclusion: Aggressive and early excision is needed because malignant fibrous histiocytoma has characteristics of high malignancy with a propensity for early and distant spread. Furthermore, the patient's education about disease entity and postoperative regular follow-up for local recurrence or metastasis is very important. To prevent malignancy from secondly healing burn scar, early skin graft is recommended for patients with deep second degree burn.

  • Purpose: Most paraquat poisonings are easily diagnosed by history taking on physical examination, however, some are failed to be diagnosed initially if the poisoning was veiled. The purpose of this study was to explore the clinical characteristics of veiled paraquat poisoning. Methods: We retrospectively reviewed the medical records of patients whose discharge diagnosis was paraquat poisoning in one university teaching hospital between 1 Jan, 2001 and 31 Dec, 2010. Veiled paraquat poisoning was determined when there was a positive urine paraquat kit in patients who did not mention paraquat poisoning in an initial physical examination or had unknown cause of pulmonary fibrosis, acute renal failure, or multi-organ failure. Results: Of the 117 patients with paraquat poisoning during the study period, 6 patients (5.1%) had veiled paraquat poisoning. The clinical characteristics were 1) proteinuria - 6 (100%), 2) increased creatinine - 4 (66.7%), 3) green skin stains - 2 (33.3%), 4) mucosal ulcer - 3 (50%). Blood chemistry results were variable. Conclusion: We should suspect veiled paraquat poisoning for patients who have proteinuria, increased creatinine, green skin stain, mucosal ulcer and vomiting, or if they have rapidly progressing acute renal failure or multi-organ failure with unknown cause, even if patients didn't mention about paraquat poisoning upon the initial physical examination. In cases with the above clinical conditions, a thorough repeated physical examination including history taking and use of urine paraquat kits should be performed.

  • An 11-year-old, female Miniature Schnauzer dog was presented with recurrent skin ulcer of the second metatarsal region in the right hindlimb following metatarsal resection. Physical examination revealed an ulcerated and bleeding lesion of the second metatarsal region in the right hindlimb. Impression smears of the ulcerative lesion confirmed numerous degenerated neutrophils and mixed bacterial infection. Initially, the dog was treated with antibiotics and povidone-iodine flushing for the control of deep pyoderma. Because the skin lesion had been deteriorated over time despite of topical and systemic treatments, skin biopsy was performed. Histopathologic examination indicated squamous cell carcinoma based on the features of multiple nests of squamous neoplastic cells and mitotic figures. Although amputation of the right hindlimb was performed, the dog was expired five months later because of tumor metastasis to the lung and the popliteal lymph node. This is the first case report describes malignant digital squamous cell carcinoma in Korea.

  • Cochlear implant extrusion, which is a common complication of cochlear implants, is generally repaired by a well visualized soft-tissue flap. A 61-year-old female patient with a medical history of schizophrenia who had a skin ulcer that caused cochlear implant extrusion, but that would be a stronger statement was referred to our department for removal of the implant and reconstruction of the resultant scalp defect. Accordingly, the broad defect was covered via rotation of a temporoparietal fascia flap (TPFF) using the superficial temporal artery, with the pedicle in the preauricular region as the pivot point. Coverage of TPFF was achieved with a split-thickness skin graft using the scalp as the donor site, which led to a quick recovery after the operation and satisfactory results in terms of aesthetics. This case suggests that a TPFF might be used as a flexible flap with low donor site morbidity for reconstructing cases of cochlear implant extrusion accompanied by a large full-layer scalp defect.

  • Purpose: This study was to compare the predictive validity of Norton Scale(1962), Cubbin & Jackson Scale(1991), and Song & Choi Scale(1991). Method: Data were collected three times per week from 48~72hours after admission based on the four pressure sore risk assessment scales and a skin assessment tool for pressure sore on 112 intensive care unit(ICU) patients in a educational hospital Ulsan during Dec, 11, 2000 to Feb, 10, 2001. Four indices of validity and area under the curve(AUC) of receiver operating characteristic(ROC) were calculated. Result: Based on the cut off point presented by the developer, sensitivity, specificity, positive predictive value, negative predictive value were as follows : Norton Scale : 97%, 18%, 35%, 93% respectively; Cubbin & Jackson Scale : 89%, 61%, 51%, 92%, respectively; and Song & Choi Scale : 100%, 18%, 36%, 100% respectively. Area under the curves(AUC) of receiver operating characteristic(ROC) were Norton Scale .737, Cubbin & Jackson Scale .826, Song & Choi Scale .683. Conclusion: The Cubbin & Jackson Scale was found to be the most valid pressure sore risk assessment tool. Further studies on patients with chronic conditions may be helpful to validate this finding.
