Purpose: This study describes a case report of wound care performed by a community health practitioner for a rural older adult with diabetic ulcers. Methods: Data were collected from a rural older adult who had a diabetic lower extremity ulcer, and wound dressing was applied over 20 weeks after the skin graft operation. Results: The patient visited a primary healthcare post for regular ulcer care, and a community health practitioner applied appropriate wound dressings and managed the patient's diabetic condition. Conclusion: In rural areas, where healthcare resources are scarce compared with urban areas, rural nurses, such as community health practitioners, are primarily required to manage rural residents' health problems. Advanced nursing practices such as complicated wound care should also be appropriately provided to patients by enhancing rural nurses' competencies in the changing health care environment.

This study assessed the color, polyphenol content, and sensory characteristics of dressing containing varying concentrations (0, 3, 6 and 9%) of freeze-dried Natto. We determined that the absence of freeze-dried Natto (0%) imparted the highest additive value for both L and a, b. The polyphenol contents obtained were 0.63, 0.69, 0.74, and 0.82 mg/g for 0, 3, 6 and 9% of dressing containing freeze-dried Natto, respectively. The appearance, color, taste, texture, and overall preference of dressings with freeze-dried Natto showed significant differences between the samples. The overall preference was highest at 5.92 points, with dressing containing 9% Natto. The quality characteristics of the 9% added samples exhibited significantly higher values as compared to those of the controls, raising the possibility of development as a health-functional dressing.

Chronic wounds, pressure sores, lesions, and infections of microbial origin in bedridden, paralyzed, or malnutrition patients remain the object of study of many researchers. A variety of factors behind the development of these disorders are related to the patient's immune system, making it unable to respond effectively to the treatment of the wound. These factors can be properly controlled, giving particular importance to the ethiology and stage of the wound, as well as the time periods corresponding to the replacement of the dressings. The present research reports a novel foam/soft material, ${{\small}L}$-Cys-g-PCL, with an application for decubitus/pressure ulcers, especially for wounds with a difficult healing process due to infections and constant oxidation of the soft tissues. During this work, the interactions between S. aureus and ${{\small}L}$-Cys-g-PCL foam were studied under conditions that simulate decubitus ulcers; namely, pH and exudate. The effects of duration of grafting (1 or 8 h) and pH (7.0 and 8.9) on wettability, surface energy, swelling, and porosity were also evaluated. Results showed an effective microbicidal activity exhibiting an inhibition ratio of 99.73% against S. aureus. This new ${{\small}L}$-Cys-g-PCL soft material showed saftey to contact skin, ability to be shaped to fill in sunken holes (craters) - pressure ulcers stage III - and to act as a smart material responsive to pH, which can be tailored to develop better swelling properties at alkaline pH where exudates are normally higher, so as to address exudate self-cleaning and prevention of desiccation.

Fleischmann et al. first described the concept of using sub-atmospheric pressure to treat open or infected wounds in 1993. Since then, Argenta and Morykwas developed subatmospheric, or negative pressure dressings in 1997 as a means of managing complicated wounds. Since its introduction in 1997, the vacuum-assisted closure (VAC) system has been used widely in general plastic surgery, general surgery, and orthopedic surgery to manage complicated wounds of the torso and extremities. However, there is a paucity of literature describing its use in the head and neck region, particularly in oral and maxillofacial surgery. We report a successful case of postoperative orocutaneous fistula closure using a VAC system in a 59-year male with a review of the relevant literature.

Background Various focal heating devices are popular in Korea under the cultural influence of the traditional ondol under-floor method of home heating. These devices can cause severe burn-like injuries resulting from device malfunction or extended with low heat contact. In addition to injuries under these high heat contact, burns can be occurred by low heat exposure with prolonged periods despite the devices are properly functioning. In order to develop strategies to reduce the duration of periods of illness due to low-temperature burns, we analyzed and compared treatment methods and therapeutic periods for this type of injury. Methods This retrospective study included 43 patients burned under low heat conditions. Patients were divided into an operative group and a conservative group. The patients in the operative group underwent at least one surgical excision, and were further subdivided into early and late visit groups. The conservative group was treated only with dressings. We compared the treatment periods between the operative group and the conservative group, and also compared the preparation periods and treatment periods between the two operative groups. Results The average treatment period was significantly shorter in the operative group (P=0.02). In the early visit operative group, both wound preparation and treatment were briefer than in the late visit group. Conclusions We recommend that early proper burn care and early surgical intervention, including appropriate excision, are feasible ways to reduce the treatment period of lowtemperature burn patients.

Purpose: The objective of this study is to prevent postoperative lower eyelid retraction and scleral show. There are several approaches for orbital rim reconstruction. But these techniques are sometimes difficult to perform, and have some merits and faults. Maybe most common unwanted and unpleasant result that we have experienced by subciliary incision preseptal approach is the lower eyelid retraction and the scleral show. Therefore, I want to find out the causes and the solutions for such complication. We must know the mechanics for those unpleasant result first of all. Methods: We conducted a comparison of postoperative photographs between retroseptal approach group and preseptal approach group, both with subciliary incision. In experimental retroseptal group, incision was applied at subciliary region. After elevating skin flap to preserve pretarsal muscle, not with muscle flap elevation, but direct oblique incision through the muscle, retroseptal dissection was applied to the ROOF and the septum. Fixating fracture line, periosteal and septal repair was followed by skin repair. The light compressive dressings and protection were kept in place for 7 days. The effectiveness of this operative method was made comparison with control group which the preseptal approach was applied to, by postoperative 2nd week and 2nd month. Results: Author's technique had been used in 20 patients and control group was composed of 50 patients over 19months period. There were better results in experimental group than in control group and all of experimental group had no complaint about the lower eyelid retraction and the scleral show. Conclusion: It must be known about the reason of the lower eyelid retraction and the scleral show induced by subciliary and preseptal approach. Mechanically it can be easily proved. And the solution maybe will be easier if we get more information about the mechanics. I recommend the retroseptal subciliary approach

Background Negative-pressure wound therapy (NPWT) is believed to accelerate wound healing by altering wound microvascular blood flow. Although many studies using laser Doppler have found that NPWT increases perfusion, recent work using other modalities has demonstrated that perfusion is reduced. The purpose of this study was to investigate the influence of NPWT on tissue oxygenation of the foot, which is the most sensitive region of the body to ischemia. Methods Transcutaneous partial pressure of oxygen ($TcpO_2$) was used to determine perfusion beneath NPWT dressings of 10 healthy feet. The sensor was placed on the tarso-metatarsal area of the foot and the NPWT dressing was placed above the sensor. $TcpO_2$ was measured until it reached a steady plateau state. The readings obtained at the suction-on period were compared with the initial baseline (pre-suction) readings. Results $TcpO_2$ decreased significantly immediately after applying NPWT, but gradually increased over time until reaching a steady plateau state. The decrease in $TcpO_2$ from baseline to the steady state was 2.9 to 13.9 mm Hg (mean, $9.3{\pm}3.6$ mm Hg; $13.5{\pm}5.8%$; P<0.01). All feet reached a plateau within 20 to 65 minutes after suction was applied. Conclusions NPWT significantly decrease tissue oxygenation of the foot by 2.9 to 13.9 mm Hg. NPWT should be used with caution on feet that do not have adequate tissue oxygenation for wound healing.

Objective : Radiodermatitis is a common sequelae in 95% of patients receiving radiation therapy, which is important to be well managed as it can affect the patient's quality of life as well as the cancer treatment schedule. The aim of this study is to review and summarize the interventions available for the treatment of acute radiodermatitis, including traditional Korean medicine, and to propose treatment algorithms for clinicians. Methods : To collect studies about managements for radiodermatitis, domestic and foreign database were used such as Korean journal of traditional knowledge portal (KTKP), Korean studies information service system (KISS), national discovery or science leaders (NDSL), and oriental medicine advance searching integrated system (OASIS), Pubmed, Google scholar and Scopus. Results : Thirty-two studies were selected. There were nine studies on usual care and dressing, eleven studies on chemical agents, two studies on biological preparations, and ten studies on herbal medicines. Conclusion : Hygienic options and dressings have proved to be useful in the management of radiodermatitis. Chemical agents such as corticosteroid, statin, and topical antibiotic agent have proved to alleviate symptoms and severity, regenerate damaged skin, and prevent secondary infection. In biological preparations, EGF (epidermal growth factor) and GM-CSF (granulocyte-macrophage colony-stimulating factor) could be used to protect skin and prevent radiodermatitis. For herbal medicines, Calendula, catechin, β-sitosterol, and Jaungo (紫雲膏) may be effective for symptoms including pain, itching, and burning sensation induced by radiation therapy. Because of some research with conflicting results, further studies are needed to propose an algorithm for more optimal treatments.

인공피부 관련 기술은 1980년대에서는 혈액이나 생체 이식에 적합한 필터/붕대/패드/기타 피복용품의 제조기술(A6IF)에 속하는 것으로 모 또는 피부이식기술 분류(A6IF-002/10)가 주요 연구과제로 진행되어 오다가 1990년대 이후에는 보철 또는 보철물을 피복 또는 코팅을 위한 소재분류(A6IL-027/00)로 전환되어 현재에 이르고 있다. 이것은 초기 피부이식 자체의 외과적인 처리기술에 필요한 기술로 시작되어 점차 소재기술로 큰 전환점을 맞이하였고, 즘 더 나아가서 세포 및 조직 배양기술 (Cl2N-005/00, Cl2N-005/06)의 접목으로 고도화되고 있다는 것을 확인할 수 있다. 전반적인 기술적 수준은 미국이 가장 앞서 있으며, 유럽, 일본, 한국의 상황은 북미 지역에 비해 약간 뒤지고 있으나, 세포를 배양하는 기술적인 수준의 차이는 크지 않다고 보여지며, 아직도 배양피부의 색상, 항균성, 생체적합성 등에서 개선의 과제가 남아 있다고 보여진다 따라서 부작용 가능성 해소, 보급 확대를 위한 제품생산 코스트 인하, 대량생산 시스템 구축, 제품인식도 제고 등이 필요한 것으로 파악되고 있다.
