  • Purpose: This study was based on the Korean Foot and Ankle Society (KFAS) member survey and aimed to report the current trends in the management of syndesmotic injuries over the last few decades. Materials and Methods: A web-based questionnaire containing 36 questions was sent to all KFAS members in September 2021. The questions were mainly related to the preferred techniques and clinical experiences in the treatment of patients with syndesmotic injuries. Answers with a prevalence ≥50% of respondents were considered a tendency. Results: Seventy-six (13.8%) of the 550 members responded to the survey. The results showed that the most preferred method to diagnose a syndesmotic injury was magnetic resonance imaging (MRI). Intraoperatively, the external rotation stress test and the Cotton test were most frequently used to confirm syndesmotic diastasis. The reduction was usually done by a reduction clamp. One 3.5-mm screw was used most frequently over three cortices at 2~4 cm above the ankle joint. The preferred ankle position during fixation was 0° dorsiflexion. Removal of the syndesmotic screw was routinely done by most surgeons, mainly because of the limitation of movement and risk of screw breakage. Factors that affect suture button selection included non-rigid fixation which enables adequate fixation, early weight-bearing, and an infrequent need to remove the hardware. Inadequate reduction was considered the main factor that affects poor prognosis. Conclusion: This study proposes updated information about the current trends in the management of syndesmotic injuries in Korea. Consensuses in both the diagnostic and therapeutic approach to patients with syndesmotic injury were identified in this survey study. This study may raise the awareness of the various possible approaches toward the injury and should be used to further establish a standard protocol for the management of syndesmotic injuries.

  • 본 연구는 개에서 난소자궁절제술과 난소절제술의 실시가 동물의 통증행동과 스트레스에 미치는 영향을 비교하고, 임상적용 가능성을 평가하기 위하여 실시되었다. 13 마리의 건강한 암컷 중 (4.2-5.5 kg) 6 마리의 개에서 난소절제술이 행하여졌고, 7 마리에서 난소자궁절제술이 이루어졌다. 술 후 두 그룹 간에 수술 시간, 마취 시간, 복벽의 절개 길이를 비교하였다. 또한 술 전과 술 후 1, 2, 4, 6, 12, 24 시간째에 Short form of composite measure pain scale (CMPS-SF) 를 사용하여 통증 점수를 측정하였고 혈중 glucose 와 creatine kinase 그리고 cortisol 수치를 측정하였다. 난소자궁절제술을 시행한 그룹에서는 난소절제술을 시행한 그룹에 비해 유의적으로 (p < 0.05) 긴 수술 시간, 마취 시간, 복벽 절개 길이를 나타내었다. Two-way ANOVA test 결과 CMPS-SF에 의한 통증점수가 두 그룹 간에 유의적 (p < 0.05) 차이를 보였으며 술 후 1, 2, 4, 6 시간째 난소절제술을 행한 그룹에서 유의적으로 낮은 수치를 나타내었다. Glucose 의 경우 난소자궁절제술을 행한 그룹에서는 술 전과 비교해 유의적 (p < 0.05) 농도 증가가 술 후 1 시간째에 나타났으나 난소절제술을 행한 그룹에서는 술 후 전체 관찰기간 동안 유의적 농도 증가가 관찰 되지 않았다. Creatine Kinase 의 경우 난소자궁절제술을 행한 그룹에서는 술 전과 비교하여 술 후 1, 2, 4, 6, 12 시간째에 유의적 (p < 0.05) 농도 증가를 나타내었으나 난소절제술 그룹의 경우 술 후 4, 6, 12 시간째에만 술 전과 비교하여 유의적 (p < 0.05) 농도 증가를 나타내었다. Cortisol 의 경우 두 그룹 모두 술 후 1, 2 시간째에 유의적인 (p < 0.05) 농도 상승을 나타내었다. 본 연구 결과 난소절제술을 이용한 암캐의 중성화 수술 방법은 난소자궁절제술에 비해 짧은 복벽 절개, 수술 시간, 마취 시간을 요하며, 적은 술 후 통증과 스트레스를 유발하므로 난소절제술을 시행하는 것이 환자에게 바람직할 것으로 판단된다.

  • The purposes of study was: 1. To identify the direction and scope of research activities in Korean Nursing. 2. To discuss the unique problems present in Korea that warrant nursing research. 3. To delineate the factors that facilitate and/or hinder nursing research in Korea. This study was conducted at six colleges of nursing in Korea. The schools which were selected had doctoral programs at the time, the data were collected in 1990. Four of the schools were located in the metropolitan area of the capital city, Seoul, and two were in two other cities similar in size. The total population of the study was 283 nurses. The instrument for the research was the English version of Research Profile Questionnaire which was translated into Korean by the researchers and was validated in its translation by two professors. A pretest procedure was done before the data collection process. Of the population of 283, 210 subjects received the questionnaire and 150 subjects responded(71.4%). Excluding incomplete questionnaires, 141 questionnaires were utilized for data analysis. Data were analyzed using descriptive statistics. Responses to open-ended questions were content analyzed for themes and categories. Results of the study were as follows : Respondents currently , involved in nursing research numbered 108(76.6%), but 33(23.4%) did not have any research experience. The inexperienced respondenLs tended to be younger than the experienced subjects and most( 60.6%) were employed in hospitals, while 82.4 percent of the experienced nurses were employed in nursing schools. Among the respondents with research experience, 68.5 percent were involved in one to three projects and 31.5 percent were engaged in four or more projects. The experienced nurses indicated that nursing research in Korea is active. On the other hand, the responses of the inexperienced were that nursing research is not active. The most frequently selected research subjects were patients(76.9%, 83 respondents) followed by nurses, healthy persons and nursing students. The relatively high percentage of healthy persons as study subjects, could be explained as a concern of nurses for healthy persons as well as for ill patients. The aforememioned literature review showed a dramatic change in the kinds of study subjects; approximately 33 percent were patients but 25 percent were healthy subjects of various ages. The hospital was the prevailing research setting(67.6%) but at the same time various community settings were used. This is a changing phenomena in nursing research of Korea. Current research designed to build on previous studies amounted to 75 percent; about 39.8 percem were theory and hypothesis generated. Over 65 recommended additional research focusing on hypothesis-testing 0:' theory building. The previously quoted literature review found that only 4.0 percent of the study quescions were developed from a theoretical framework. The most frequently listed current major focus of nursmg research was stress and adaptation. Patients with cancer, pain, social support and care of the elderly were the next most frequently reported. These concerns may reflect problems associated with a technological and industrializing societyl. The most frequently identified problem was lack of clinical research. The need for replication research and research that contributes to the accumulation of nursing knowledge were found to be rare in Korean research. A need for theory testing and theory construction research was also identified. Although advanced statistical methods were often utilized in nursing research, the results were frequently considered by the interviewers not to be applicable in practice, and readers had difficulty in comprehending the findings. Even though the number of clinical nurses involved in research is increasing, it is still considered inadequate. Among 108 respondents, 83(76.9%) gave lack of time as a barrier to conducting nursing research. Over fifty percent of the respondents reported lack of funding or, personally, low confidence in research skills as barriers. The respondents offered 183 suggestions for future emphasis in nursing research. Among the 51 areas of emphasis, clinical research received the highest number and nursing intervention was next. The findings suggested that nursing research should be based on theory, be related to practice and relevant to the situation of a unique Korean culture.

  • 서론: 최근 경제수준의 향상과 사회구조의 변화 등으로 신생활이 서구화되고 노령화 사회가 되어가면서 만성질환 및 성인병 등의 박병률이 급격히 증가하고 있다. 특히 당뇨병은 전 세계적으로 및 유병율이 계속 증가하고 있으면, 만성질환 중 주요사망 원인인 뇌혈관 질환과 심혈관계 질환의 중요한 위험요인으로 잘 알려져 있다. 그러나 당뇨병은 고혈당 자체보다는 여러 장기에 복합적으로 침범하는 합병증으로 인하여 환자자신은 물론 가족과 사회에 심각한 건강 문제와 사회, 경제적 문제를 초래하게 되는 질환이다. 그러므로 당뇨병의 치료에 있어 엄격한 혈당의 조절과 함께 정서적 스트레스에 대한 배려가 필요할 것이다. 이에 저자들은 당뇨병 환자의 과거 3개월간의 혈당조절의 지표로 알려진 당화혈색소를 기준으로 당뇨조절과 관련된 정신병리를 확인해보고자 하였다. 방법: 2004년 3월부터 2004년 8월까지 가톨릭대학교 성빈센트병원 내분비내과에서 치료 중인 환자 55명을 대상으로 하였으며, 이 중 당화혈색소가 7%이하인군을 혈당조절 양호군으로 하였다. 이들에 대하여 사회 인구학적인 변인에 대한 문항, Beck의 Beck Depression Inventory(BDI), Spielberger의 State-Trait Anxiety Inventory (STAI), Taylor의 Tronto Alexithymia Scale (TAS), 고경봉의 스트레스반응척도(SRI)를 사용하여, 혈당조절 양호군과 불량군간의 차이를 비교하였다. 결과: 1) 대상군 55명의 평균나이는 $49.9{\pm}9.9$세(연령분포 : $24{\sim}67$세)였으며, 이 중 남자가 49.1%(27명), 여자가 50.9% (28명)이었고, 평균 유병기간은 $47.6{\pm}62.6$개월, 평균 신체질량지수는 $25.3{\pm}4.2$로 측정되었다. 총 55명중에서 혈당조절 양호군은 10명(평균나이 $47.2{\pm}12.3$세, 남자 60%, 여자 40%)이었고, 혈당조절 불량군은 45명 (평균나이 $50.5{\pm}9.4$세, 남자 46.7%, 여자 53.3%)이었다. 2) 두 군간에서 나이, 성별, 신체질량지수 등의 인구학적 변인에서 유의한 차이는 없었으나, 당뇨병 유병기간에서 혈당조절 양호군이 $12.2{\pm}55.4$개월, 혈당조절 불량군이 $55.4{\pm}66.6$개월로 혈당조절 양호군이 유의하게 짧은 유병기간을 보이고 있었다(p=0.000). 3) 혈당조절 양호군과 불량군의 상태불안의 평균점수는 각각, $38.7{\pm}3.8$점, $43.7{\pm}6.7$점이었고, 특성불안의 평균점수는 각각, $36.9{\pm}5.7$점, $41.5{\pm}6.4$점으로 두군 모두에서 상태불안(p=0.029)과 특성불안(p=0.043)에 있어서 유의한 차이를 보이고 있었다. 4) 우울증상척도, 감정표현불능척도, 스트레스반응척도에서는 혈당조절 양호군과 불량군 모두에서 유의한 차이가 없었다. 결론: 이상의 결과에서 당뇨조절에 문제가 있는 군은 그렇지 않은 군보다 높은 상태불안 및 특성불안을 겪고 있는 것으로 확인되었다. 당뇨환자의 치료에 있어서 환자들이 느끼는 불안에 대한 통합적인 접근이 필요할 것으로 사료된다.

  • Compression Hip Screw (CHS) is one of the most widely-used prostheses for the treatment of intertrochanteric fractures because of its strong fixation capability. Fractures at the neck and screw holes are frequently noted as some of its clinical drawbacks, which warrant more in-depth biomechanical analysis on its design variables. The purpose of this study was to evaluate changes in the strength with respect to the changes in design such as the plate thickness and the number of screw holes. Both mechanical test and FEM analysis were used to systematically investigate the sensitivities of the above-mentioned design variables. For the first part of the mechanical test, CHS (n=20) were tested until failure. The CHS specimens were classified into four groups: Group Ⅰ was the control group with the neck thickness of 6-㎜ and 5 screw holes on the side plate, Group Ⅱ 6-㎜ thick and 8 holes, Group Ⅲ 7.5-㎜ thick and 5 holes, and Group Ⅳ 7.5-㎜ thick and 8 holes. Then, the fatigue test was done for each group by imparting 50% and 75% of the failure loads for one million cycles. For the FEM analysis, FE models were made for each group. Appropriate loading and boundary conditions were applied based on the failure test results. Stresses were assessed. Mechanical test results indicated that the failure strength increased dramatically by 80% with thicker plate. However, the strength remained unchanged or decreased slightly despite the increase in number of holes. These results indicated the higher sensitivity of plate thickness to the implant strength. No fatigue failures were observed which suggested the implant could withstand at least one million cycles of fatigue load regardless of the design changes. Our FEM results also supported the above results by showing a similar trend in stress as those of mechanical test. In summary, our biomechanical results were able to show that plate thickness could be a more important variable in design for reinforcing the strength of CHS than the number of screw holes.

  • Fructose-1, 6-diphosphate (FOP), a glycolytic metabolite is reported to ameliorate inflammation and inhibit the nitric oxide production in murine macrophages stimulated with endotoxin. It is also reported that FOP has cytoprotective effects against hypoxia or ischemia/reperfusion injury in brain and heart. In this study, we examined whether FDP has protective effects on UV-induced oxidative damage in skin cell culture system and human skin in vivo. FDP had a protective role in UVB-induced LDH release and ROS accumulation in HaCaT although it did not show direct radical scavenging effect in the experiment using 1, 1-diphenyl-2-picrylhydrazyl (DPPH). FDP also preserved cellular GSH content after UV irradiation in HaCaT and normal human fibroblast culture system. Cellular oxidative stress induces multiple downstream signaling pathways that regulate expression of multiple gene including MMP-1 and collagen, we examined the effects of FDP on UV-induced alteration of these protein expression in fibroblast culture and human skin in vivo. The increased MMP-1 expression in fibroblast and human skin by UV irradiation was significantly decreased by FDP. FDP also prevented the UV-induced decrease of collagen expression in fibroblast and human skin. Moreover, the decreasing the intracellular levels of reducing equivalents in human fibroblast by glutathione (GSH) depletion lowered the UVA dose threshold for reduction of procollagen expression, indicating that the differences of glutathione contents define the susceptibility of fibroblasts towards UV-induced reduction of procollagen expression. FDP also preserved cellular GSH content after UV irradiation, indicating that FDP has protective effects on UV-induced reduction of procollagen expression, which are possibly through maintaining intracellular reducing equivalent. Based on these premises, we examined the effect of daily use of a moisturizer containing FDP on facial wrinkle in comparison with vehicle moisturizer lacking FDP. In the clinical study, FDP significantly decreased facial wrinkle compared with vehicle alone after 6 months of use. Our results suggest that FDP has anti-aging effects in skin by increasing cellular antioxidant system and preventing oxidative signal and inflammatory reaction. Therefore FDP may be useful anti-aging agent for cosmetic purpose.
