Background Chronic wounds occur due to failure of the normal healing process, associated with a lack of deposition of cellular components and a suitable microenvironment such as the extracellular matrix (ECM). Acellular dermal matrix (ADM) is viewed as an ECM substitute, and a paste-type ADM has recently been introduced. We hypothesized that CGPaste, an injectable paste-type ADM, could serve as a scaffold and promote wound healing. Methods We retrospectively studied seven patients in whom CGPaste was applied between 2017 and 2018, who had pressure ulcers, necrotizing fasciitis, diabetic foot ulcers, traumatic defects, and osteomyelitis. The goal of applying CGPaste was to achieve complete wound healing with re-epithelialization or growth of granulation tissue, depending upon the wound bed status. CGPaste was injected based on the wound size along with the application of a dressing. Results Four of the seven patients showed granulation tissue on their wound bed, while the other three patients had a bony wound bed. The mean wound area was $453.57mm^2$ and the depth was 10.71 mm. Wound healing occurred in five of the seven patients (71.43%). The mean duration of complete healing was 2.4 weeks. Two patients showed failure due to paste absorption (29.57%); these patients had wound beds comprising bone with relatively large and deep wounds ($40{\times}30$ and $30{\times}20mm^2$ in area and 15 and 10 mm in depth). Conclusions CGPaste is an effective option for coverage of small and deep chronic wounds for which a flap operation or skin grafting is unfeasible.

Purpose: We present our experience involving the management of this disease, identifying prognostic factors affecting treatment outcomes. Methods: The patients treated for Fournier gangrene at our institution were retrospectively reviewed. Data collected included demographics, extent of soft tissue necrosis, predisposing factors, etiological factors, laboratory values, and treatment outcomes. The severity index and score were calculated. Multivariate regression analysis was used to determine the association between potential predictors and clinical outcomes. Results: A total of 41 patients (male:female = 33:8) were studied. The mean age was 54.4 years (range, 24-79 years). The most common predisposing factor was diabetes mellitus (n = 19, 46.3%). Sixteen patients (39.0%) were current smokers. Seven patients had chronic kidney disease. The most frequent etiology was urogenital lesion (41.5%). The mortality rate was 22.0% (n = 9). Multivariate regression analyses showed that extension of necrosis beyond perineal/inguinal area and pre-existing chronic kidney disease were significant and independent predictors of mortality. Extension of necrosis beyond perineal/inguinal area was a significant predictor of increased duration in the intensive care unit and hospital stay. In addition, pre-existing chronic kidney disease was a significant predictor of flap reconstruction in the wound. Conclusion: Fournier gangrene with extensive soft tissue necrosis and pre-existing chronic kidney disease was associated with poor prognosis and complexity of patient management. Early recognition of dissemination and premorbid renal function is essential to reduce mortality and establish a management plan for this disease.

Objective: Extracorporeal shock wave therapy (ESWT) is a nonsurgical treatment alternative to surgery for various musculoskeletal diseases that have traditionally been difficult to treat conservatively, including calcific tendinitis, tennis elbow, and plantar fasciitis. This study evaluated the effect of focused and radial shock wave therapy for calcific tendinitis of the shoulder. Design: Randomized controlled study Methods: Forty participants with calcific tendinitis were randomized into focused shock wave therapy (FSWT, n=20) and radial shock wave therapy (RSWT, n=20) groups. Patients were examined before and one week after treatment. Pain intensity was subjectively assessed using the visual analogue scale and function was assessed using the Constant-Murley score (CMS) and range of motion (ROM). Results: The results showed a significant decrease in pain and significant increase in shoulder mobility and function in both groups. However, FSWT was significantly more effective than RSWT, based on CMS and ROM assessment. Conclusions: Although it is possible to raise the energy intensity of RSWT to increase the depth at which the energy becomes dispersed, higher energy intensity is associated with a greater risk of severe neurovascular damage, and that high-intensity stimulation can cause adverse effects such as pain and petechiae. Therefore, FSWT is considered to be a safe and effective method for treating tendinous lesions while minimizing adverse effects. In conclusion, both FSWT and RSWT can reduce pain and increase mobility and function. FSWT can be considered as an alternative for calcific tendinitis of the shoulder.

Objectives This study examined recent domestic and international clinical research trends in Gua sha therapy to suggest future direction for research. Methods We used six domestic and international databases (Research Information Sharing Service, Korean studies Information Service System, Oriental Medicine Advanced Searching Integrated System, PubMed, Embase, Cochrane Library) to select clinical studies with an original text in English or Korean published after 2018. Results Finally, 55 studies were selected. Randomized controlled trials accounted for the largest amount with 42 studies. Instrument assisted soft tissue mobilization was the most frequent term referring to Gua sha. Muscle shortening, limited range of motion, and plantar fasciitis were the most common symptoms, with six cases each. Additionally, there were two studies targeting symptoms other than the musculoskeletal system. Conclusions Additional research is needed on the effects of Gua sha therapy on the back of the lower extremities and hip joints, and research is needed on the possibility of their clinical use for diseases or symptoms other than those of the musculoskeletal system. And standards for the terminology of Gua sha and the types and methods of applied interventions are needed.

Most purulent maxillofacial infections are of odontogenic origin. Treatment of infection includes the surgical intervention, such as incision and drainage, and adjunctive treatment. The use of high-dose antibiotics is also indicated. The choice of an antibiotics should be based on the knowledge of the usual causative microbes and the results of antibacterial sensitivity test. We have undertaken clinical studies on 119 patients in Dept. of Oral and Maxillofacial Surgery, Inha University Hospital from January 2000 to December 2007. Many anaerobic microbes are killed quickly when exposed to oxygen. Thus the needle aspiration techniques and the transfer under inert gas were used when culturing. The aim of this study was to obtain informations for the bacteriologic features and the effective antimicrobial therapy against maxillofaical odontogenic infections. The obtained results were as follows: 1. The most frequent causes of infections were odontogenic (88.3%), and in odontogenic cause, pulpal infections were the most common causes(53.8%). 2. The buccal and submandibular spaces (respectively 23.5%) were the most frequent involved fascial spaces, followed by masticator spaces (14.3%). 3. The most common underlying medical problems were diabetes (17.6%), however the relation with prognosis was not discovered. 4. The complications were the expiry, mediastinitis, necrotizing fasciitis, orbital abscess, and osteomyelitis. 5. The most common admission periods were 1-2 weeks, and the most patients were discharged within 3 weeks. However, patients who admitted over 5 weeks were about 10%. 6. A total of 99 bacterial strains (1.1 strains per abscess) was isolated from 93 patients (78.2%). The most common bacterium isolated was Streptococcus viridans (46.2%), followed by $\beta$-hemolytic group streptococcus (10.1%). 7. Penicillins (penicillin G 58.3%, oxacillin 80.0%, ampicillin 80.0%) have slightly lower sensitivity. Thus we recommend the antibiotics, such as glycopeptides (teicoplanin 100%, vancomycin 100%) and quinolones (ciprofloxacin 90.0%) which have high susceptibility in cases in which peni cillin therapy failed or severe infections.

Objectives The purpose of this review is to investigate studies of Scolopendrid pharmacopuncture and the evidence of it's effects in order to suggest a better research method in the future. Methods We retrieved numbers of clinical studies about Scolopendrid pharmacopuncture from 7 Korean web databases, using key words such as 'Scolopendrid', 'Scolopendrid AND Pharmacopuncture'. This study had been conducted from 1st May 2013 to 31th July 2013. Controlled studies and case studies were only used for this study. Clinical studies that we picked from the databases were classified according to the diseases that those studies are about, and from these clinical studies, we are to research what has to be improved generally in clinical researches. Results 18 case studies, 4 controlled studies had been under research. Scolopendrid pharmacopuncture has a therapeutic effect mainly in musculoskeletal and neurological diseases such as herniated intervertebral disc, carpal tunnel syndrome, swollen leg, feeling of cold on legs, wrist ganglion, lateral epicondylitis, radial nerve palsy, cervical myelopathy, cauda equina syndrome, postauricular pain; as an early symptom of Bell's palsy, pain of popliteal part, gout, plantar fasciitis, cellulitis, frozen shoulder, pain of hip adductors. However objectivity and reliability of the Scolopendrid pharmacopuncture studies still remains controversial. Conclusions It has been suggested that there are positive effects of Scolopendrid pharmacopuncture therapy in treating specific diseases (especially neuromusculoskeletal diseases). However, this narrative review can't conclude and prove that the Scolopendrid pharmacopuncture has positive effectiveness on these diseases unlike systematic review. So, in order to put Scolopendrid pharmacopuncture therapy to use for many kinds of diseases in more reasonable ways, it is essential to build well-designed clinical research tools. In the future, abundant case studies, more follow-up trials and randomized controlled trials based on the korean medicine should be done to use Scolopendrid pharmacopuncture for a clinical purpose.

$TGF-{\beta}_1$ is a potent chemotactic factor for inflammatory cells and fibroblasts. It also stimulates the celluar source and components of extracellular matrix and the production of proteinase inhibitors. Collectively, these biologic activities lead to the accumulation and stabilization of the nascent matrix, which is vital to infection control. The objective of this study is to investigate production of $TGF-{\beta}$ in vitro fibroblast culture in the presence of Staphylococcus enterotoxin B(SEB) and/or lipopolysaccharide(LPS) and to elucidate the role of $TGF-{\beta}_1$ which may be responsible for infection control. The fibroblasts were originated from gingiva and facial dermis in 26 year-old male patient. In the presence of LPS($0.01{\mu}g$, $0.1{\mu}g$, $1.0{\mu}g$), SEB($0.01{\mu}g$, $0.l{\mu}g$, $1.0{\mu}g$) respectively, $cells(5{\times}10^3ml)$ were cultivated in vitro. At 1, 3, and 5 days after incubation, cells were counted. Also, $cells(2.5{\times}10^5ml)$ were cultivated in EMEM with LPS(0.01, 0.1 and $1.0{\mu}g$), SEB(0.01, 0.1 and $1.0{\mu}g$) respectively and $LPS(0.1{\mu}g)$ and $SEB(0.1{\mu}g)$ in combination for 24, 48, and 72 hours respectively. Culture supernatants were harvested at 1, 2, and 3 days after incubation period and triplicate culture supernatants were pooled and $TGF-{\beta}_1$ was assayed in duplicate. The results were as follows. 1. In gingival fibroblast induced with SEB and LPS respectively or in combination, the suppression of cell Proliferation occurred very significantly since 3 days after incubation, compared with the control and the production of $TGF-{\beta}_1$ occurred very significantly at 1 day after incubation, compared with the control. 2. In facial dermal fibroblast induced with SEB and LPS respectively or in combination, the suppression of cell proliferation occurred very significantly at 1 day after incubation, compared with the control. In SEB exposure, the production of $TGF-{\beta}_1$ was decreased very significantly at 1 day after incubation, compared with the control. However, in LPS, SEB and LPS exposure, the production of $TGF-{\beta}_1$ was increased very significantly at 1 day after incubation, compared with the control. In conclusion, the concentration of bacterial toxins and the incubation period correlated with cell proliferation and production of $TGF-{\beta}_1$ very significantly. The gingival and facial dermal fibroblasts have different phenotype each other The orchestrated understanding of fibroblast proliferation and $TGF-{\beta}_1$ production play an important part in host defense against the bacterial Infection and may prevent tissue necrosis such as necrotizing fasciitis and life-threatening syndrome such as multiple organ failure.

본 연구에서는 국내에서 주로 소비되고 있는 감성돔(A. schlegeli), 참돔(P. major), 돌돔(O. fasciatus) 및 벵에돔(G. punctata)에 대한 기능성 식품으로서 영양학적 가치를 평가하기 위하여 인체 위암세포(AGS)와 인체 결장암세포(HT-29)에 대한 세포 독성 효과를 비교 연구하였다. 4종의 돔 A+M 및 MeOH 추출물들을 AGS 암세포에 처리했을 때 A+M추출물의 경우 첨가농도 5 mg/ml에서 참돔(P. major)과 감성돔(A. schlegeli) 추출물은 80% 이상의 높은 세포독성 효과를 나타내었으며 그 다음으로 벵에돔(G. punctata)이 70%, 돌돔(O. fasciatus)이 53%의 세포독성 효과를 보였다. MeOH 추출물의 경우 참돔(P. major)과 돌돔(O. fasciatus) 추출물이 약 80% 이상의 세포독성 효과를 나타났으며, 이어서 감성돔(A. schlegeli)과 벵에돔(G. punctata) 추출물이 약 70% 정도의 세포독성 효과를 보였다. 4종의 돔의 HT-29 암세포에 대한 세포독성 효과는 AGS 암세포의 결과와 비교했을 때 세포독성 효과는 다소 낮았다. 참돔(P. major), 감성돔(A. schlegeli), 돌돔(O. fasciitis) 및 벵에돔(G. punctata)의 A+M 추출물의 $IC_{50}$ 값은 각각 3.35, 6.16, 6.17 및 4.47 mg/ml이었고 MeOH 추출물의 경우 $IC_{50}$ 값은 각각 3.61, 5.52, 2.07, 및 6.06 mg/ml이었다. 이상의 결과로부터 4종 돔 중에서 참돔(P. major) 추출물에 의한 세포독성 효과가 상대적으로 높아 참돔(P. major) 추출물을 용매 극성에 따라 분획하여 얻어진 n-hexane, 85% aq. MeOH, n-BuOH 및 water 분획물들에 의한 인체 암세포에 대한 세포독성 효과를 알아 본 결과 85% aq. MeOH 분획물에 의한 AGS 및 HT-29암세포에 대한 $IC_{50}$ 값은 각각 0.33 및 1.58 mg/ml로 나타났다. 따라서 참돔(P. major)의 85% aq. MeOH 분획물은 AGS 및 HT-29 세포 모두에서 가장 높은 세포독성 효과를 보여 85% aq. MeOH 분획물에 활성물질이 함유되어 있을 것으로 기대되고 본 연구 결과를 기초자료로 하여 향후 참돔의 다양한 생리활성 규명이 필요하다고 사료된다.

목적: F-18 FDG PET은 근골격계 종양에서 양성과 악성병변을 감별하는 유용성에 대하여 다양한 결과가 보고되고 있다. 저자들은 F-18 FDG를 이용한 PET/CT로 근골격계 종양의 maxSUV를 분석하고 비교하여 유용성을 알아보았다. 대상 및 방법: 치료 전 46개 병소(연부 조직 종양 양성/악성 : 11/12, 골종양 양성/악성 9/14)에 대하여 F-18 FDG PET/CT를 시행하였으며, 조직학적 검사로 확진하였다. 악성과 양성을 구분하는 maxSUV 절단값은 연부 조직 종양에서는 4.1, 골종양에서는 3.05로 하였다. 결과: 연부 조직 종양에서 양성(R=11; maxSUV $3.4{\pm}3.2$)과 악성(n=12; maxSUV $14.8{\pm}12.2$) 간에 maxSUV는 통계학적으로 유의하게 (p<0.001) 차이가 있었다. 민감도와 특이도는 각각 83%, 91%였다. 그러나 골종양에서는 양성 종양(n=9; maxSUV $5.4{\pm}4.0$)과 악성 골종양(n=14; maxSUV $7.3{\pm}3.2$) 간에 통계학적으로 유의한 차이를 보이지 않았다. 연부 조직 종양에서는 결절성 근막염이 위양성으로 나타났고(maxSUV=12.4) 골종양에서는 섬유성 골이형성증과 랑게르한스세포 조직구증식증 2예 및 골모세포종이 있었다. 결론: 연부 조직 종양에서 maxSUV는 양성과 악성을 감별하는데 유용하였다. 그러나 골종양의 경우에는 maxSUV가 낮은 경우에는 악성을 배제할 수 있었으나, maxSUV가 높은 경우에는 조직학적으로 조직구나 섬유모세포 등이 포함된 종양의 감별진단을 고려하여야한다.
