Background: The aim of this study was to understand the importance of professional oral care for inpatients by examining the type and frequency of surgery and hospital discharge period at dental hospitals, and identify the types of professional oral care actually in progress. Methods: In this study, the type of surgery and length of hospitalization were investigated among patients admitted to the dental hospital for oral and maxillofacial surgery, and the professional oral care status of inpatients who had difficulty self-managing their oral care was retrospectively identified by collecting data on oral care before and after surgery, including the type and frequency. Results: The majority of inpatients at dental hospitals were male (57.6%), elderly patients over 60 years accounted for 20% of patients, and the average length of hospitalization was 4 days. In the 20s (aged 20~29 y), the number of orthognathic surgery patients (73.1%) was high, and the incidence of cysts was high in middle-aged patients. Regarding the oral care of hospitalized patients, scaling was performed once by a dentist before surgery. After surgery, surgical dressings using H₂O₂ balls were applied and oral care education was introduced before discharge. Conclusion: Based on the results of this study, professional oral care is essential to prevent infection and complications caused by oral bacteria among inpatients at dental hospitals. It is necessary to use various oral hygiene aids for inpatients and to conduct effective oral care instruction according to each patient's situation. In addition, it is necessary to raise awareness and the role of dental hygienists in professional oral care.

Background Chitosan (CS) is a well-known antimicrobial dressing material. Moreover, widely used amniotic membranes contain growth factors beneficial for wound healing. Herein, we created a novel amnion-conjugated CS-alginate membrane dressing and tested its wound healing potency in a diabetic swine model. Methods The bovine amniotic powder growth factor contents were evaluated by protein assay, and the powder's wound healing effects were assessed in vitro by HaCaT cell scratch closure. In vivo, two minipigs developed streptozotocin-induced diabetes. Serial serum glucose measurements and intravenous glucose tolerance tests were performed to confirm their diabetic status. Twelve square-shaped wounds created on each pig's back were randomly divided into control (n = 4), CS (n = 4), and amnion-CS (AC; n = 4) groups and treated accordingly with different dressings. Wound healing in each group was assessed by measuring wound contraction over time, capturing wound perfusion with indocyanine green (ICG) angiography, and histologically analyzing inflammatory markers. Results Amniotic powder elution promoted HaCaT cell migration in the scratch wound model, suggesting its beneficial in vitro wound healing effects. In vivo, the CS and AC groups showed earlier wound contraction initiation and reepithelialization and earlier wound perfusion improvement by ICG angiography than the control group. Additionally, the wound size of the AC group at week 3 was significantly smaller than those in the control group. There was no significant difference in the numbers of acute and chronic inflammatory cells between the groups. Conclusion The amnion-conjugated CS-alginate membrane, as well as CS dressing alone, could be a favorable dressing option for diabetic wounds.

Purpose: Driveline infection (DLI) is one of the major adverse events of Left Ventricular Assist Device (LVAD). The purpose of this study was to explore the incidence of DLI according to the driveline dressing methods. Methods: This study was a retrospective cohort study that investigated the medical records of 75 patients who implanted LVAD from January 2015 to December 2020 at a hospital in Seoul, Korea. Traditionally, sandwich dressing method was applied until October 2019, after which newly winded dressing method was adopted for driveline dressing to LVAD patients. The outcome variables were compared between sandwich dressing method applied group (n=41) and winded dressing method applied group (n=34). The follow-up period for DLI was 1 year. Results: When compared participants' characteristics, there was no difference between the two groups, except the type of LVAD device. The incidence of DLI was 17.1% in sandwich dressing group, while no infection was found in winded dressing group (p=.011). Conclusion: Although there were difference in the LVAD devices, it is considered that winded dressing contributed to the reduction of DLI. Further research on standardized dressing methods was required for DLI prevention in Korea.

Objectives : The purpose of this review study is to identify clinical indications of Hwangryunhaedok-tang(HHT) external application and to suggest directions for future research and treatment by analyzing domestic cases applying HHT external treatment except for pharmacopuncture research. Methods : We searched 235 studies published in Korean since 2000 from four domestic databases: Oriental Medicine Advanced Searching Integrated System(OASIS), Research Information Sharing Service(RISS), Korean Traditional Knowledge Portal(KTKP), and Korean studies Information Service Systems(KISS) using keywords such as 'HTT and external use', 'HHT and external agent' 'HHT and wet dressing', or 'HHT and case'. We excluded duplicate papers, papers related to acupuncture including pharmacopuncture, or papers not related to the topic. Results : We selected and analyzed seven case reports. HHT external agent was used alone in one case, as main treatment in two cases, and as adjuvant treatment in four cases. HHT external application was applied to various skin diseases accompanied by inflammation mainly in the form of wet dressings. Conclusion : HHT external agent may be effective on various skin diseases accompanied by inflammation when applied alone or in combination with other agents according to the treatment stage. Based on this results, further studies will be needed to establish the primary clinical indication of HHT external agent.

본 연구는 지방함량이 낮고 건강지향적인 고품질 오디 샐러드드레싱 개발을 위해 식초대신 오미자, 점도를 높이기 위해 생마즙을 사용하여 샐러드 드레싱을 제조하고 그 이화학적 특성 및 항산화성을 분석하였다. 샐러드 드레싱에 첨가되는 재료는 샐러드베이스(플레인 요거트:마요네에즈:생크림=8:1:1):오디분쇄물:오미자청:생마즙=4:4:6:1 또는 4:4:6:3 으로 첨가하였으며, 이때 첨가된 생마는 전체 샐러드 드레싱의 0,7, 18% 수준이었다. 샐러드 드레싱의 pH는 생마즙이 증가할수록 높아졌으며, 산도는 낮아졌다. 점도는 생마즙을 첨가하지 않은 대조군은 83.20 cP로 낮았으나, 생마즙 첨가량이 증가할수록 점도는 유의적으로 증가하여 생마즙 7%첨가군은 113 cP, 18% 첨가군은 125 cP 를 나타내었다(p<0.001). 유화 안정성은 생마즙 첨가량과 관계없이 49-50으로 일정한 값을 나타내었다. 색도 중 명도와 황색도는 생마즙 첨가량이 증가할수록 높아지는 경향을 나타내었다. 총 페놀성 화합물 함량은 대조군이 0.087 mg/g 이었으며, 생마즙 7% 첨가 오디 샐러드 드레싱은 0.101 mg/g, 생마즙 18% 첨가 오디 샐러드 드레싱은 0.122 mg/g 으로, 생마즙 함량이 증가할수록 총 페놀성 화합물 함량이 증가하였다. DPPH 라디칼 소거능 $IC_{50}$ 값은 대조군이 34.4 mg/mL, 생마즙 7% 첨가군이 32.3 mg/mL, 18% 첨가군이 29.7 mg/mL으로 생마 첨가량이 증가할수록 DPPH 라디칼 소거능의 $IC_{50}$ 값이 낮아져 샐러드 드레싱의 항산화능이 증가하였다. Hydroxyl 라디칼 소거능의 $IC_{50}$ 값은 대조군이 16.556 mg/mL, 7% 첨가군은 14.297 mg/mL, 18% 첨가군은 11.812 mg/mL 으로, 생마즙 함량이 증가할수록 hydroxyl 라디칼 소거능은 증가하였다. 관능적 특성으로 기호도 검사 결과, 외관, 향, 맛, 조직감에서 대조군에 비하여 생마즙 첨가군이 높았으며, 전반적인 기호도는 7% 첨가군이 가장 높았다. 이상의 결과로부터 오미자와 생마즙을 첨가한 오디 샐러드 드레싱 제조시 7%의 생마즙을 첨가할 경우 윤기, 색, 점도, 맛, 향, 기호도면에서 우수할 뿐 아니라 항산화성이 우수하여 고품질 천연 샐러드드레싱으로서 상품화 가능성이 높을 것으로 사료된다.

Purpose: Full thickness skin grafts are useful in the reconstruction of facial skin defects when primary closure is not feasible. Although the supraclavicular area has been considered as the choice of donor site for large facial skin defect, many patients are reluctant to get a neck scar and some patients do not have enough skin to cover the defect owing to the same insult occurred to the neck such as burn accident. We present several cases of reconstruction of facial skin defects by freehand full-thickness skin graft from anterolateral chest wall resulting aesthetically acceptable outcome with lesser donor site morbidity. Methods: Retrospective review was performed from March, 2007 to September, 2009. 15 patients were treated by this method. Mean age was 31.5 years. The ethiology was congenital melanocytic nevus in 7 cases, capillary malformation in 5 cases and burn scar contracture in 3 cases. Mean area of lesion was measured to 67.3 cm2 preoperatively. The lesion was removed beneath the subcutaneous fatty tissue layer. The graft was not trimmed to be thin except defatting procedure. For the larger size of defect, two pieces of grafts were harvested from both anterolateral chest wall in separation and combined by suture. Results: The mean follow up period was 9.7 months. All the grafts survived without any problem except small necrotic areas in 4 cases, which healed spontaneously under conventional dressings in 6 weeks postoperatively. Color match was relatively excellent. There were 2 cases of hyperpigmentation immediately, but all of them disappeared in a few months. Conclusion: In cases of large facial skin defects, the anterolateral chest wall may be a good alternative choice of full-thickness skin graft.

In partial thickness burn injuries, silver sulfadiazine cream 1%(SSD, $Silvadene^{(R)}$) is the most commonly used topical agent worldwide. But silver sulfadiazine cream 1% has no exudate absorption property. Usually after escar is removed from wound surface, $Silvadene^{(R)}$ is changed to saline wet gauze dressing to promote epithelization. $Aquacel^{(R)}$(ConvaTec, UK) is a 100% sodium carboxymethylcellulose Hydrofiber material. It absorbs exudates directly into the hydrofibers by vertical wicking which allows rapid uptake of liquid into the fibers. The absorbed exudate fluid can be distributed to the entire dressing rather than just over the wound surface, which results in larger fluid absorption capacity. From April, 2003 to July, 2004 a study was done with 40 patients who had variable partial thickness burns. $Aquacel^{(R)}$ dressing was compared in 21 cases to silver sulfadiazine cream 1% and saline wet gauze dressings in 19 cases. In the $Aquacel^{(R)}$ cases, the average healing time on the face was $5.36{\pm}1.69$ a day; on the hands was $8.46{\pm}2.15$ a day; and, on the neck was $6.0{\pm}2.0$ a day. With the $Silvadene^{(R)}$ and Saline wet gauze dressing, the average healing time on the face was $6.44{\pm}1.74$ a day; on the hands was $13.79{\pm}5.35$ a day; and, on the neck was $11.17{\pm}3.31$ a day. As a result, the $Aquacel^{(R)}$ group showed a shorter healing time compared to the $Silvadene^{(R)}$ and saline wet gauze dressing group and patients were satisfied because of less pain and improved comfort. In conclusion, $Aquacel^{(R)}$ is a better choice for partial thickness burn injuries because of shorter healing time, less pain and more confortable dressing.
