The pedicled fillet flap concept has been successfully applied in both the upper and lower extremities for the treatment of difficult wounds. However, in case of complete extremity amputation in eletrical burn patient, the transfer of pedicled flaps from the amputated part is not possible. In such instances, we have designed total arm musculocutaneous free-fillet flaps from the amputated limb to provide wound coverage, when replantation of the amputated part was contraindicated. now we present such a case. This technique allows immediate wound coverage without the morbidity of an additional donor site. The flap provides the ideal combination of large surface area, muscle bulk, and long vascular pedicle. It can be dissected rapidly to minimize ischemic time and could therefore be applicable to traumatic forequarter amputations.

연구목적 암 환자에게 있어 통증은 삶의 질과 예후에 큰 영향을 주는 중요한 요소로 통증을 줄이기 위한 시도가 활발히 이루어지고 있다. 이러한 관점에서 위종양 환자에게 많이 시행되는 내시경 점막하 박리법 후 통증을 줄이기 위한 노력이 계속되고 있는데, 시술 후 통증에 영향을 미치는 생물학적 요인이 많이 알려진 것에 비해 심리적 요인에 대해서는 연구가 거의 이루어지지 않았다. 본 연구의 목적은 내시경 점막하 박리법을 시술 받은 위종양 환자가 시술 후 겪는 통증에 영향을 미치는 심리적 요인을 알아보고자 하였다. 방 법 본 연구는 2015년 5월부터 2016년 6월까지 국민건강보험 일산병원에 내원하여 내시경 점막하 박리법을 시술 받은 91명의 위종양 환자를 대상으로 시행되었다. 내시경 점막하 박리법을 시술 받기 전에 사회인구학적 요인과, 불안, 우울, 회복탄력성을 평가하였다. 환자들이 호소하는 통증의 정도가 시각적 유추척도 3점 이상인 군(고통증군)과 3점 미만인 군(저통증군)으로 나누었고, 시술 후 통증에 영향을 주는 요인에 대해 독립표본 T검정 및 카이제곱 검정을 시행 후 유의한 차이를 보인 요인에 대해 로지스틱 회귀분석을 시행하였다. 결 과 고통증군이 저통증군에 비해 음주량이 낮았고 우울 점수가 높게 나타났다. 또한 고통증군이 저통증군에 비해 회복탄력성 점수가 낮았으며, 회복탄력성의 하위 항목 중 자기조절능력, 긍정성 항목에서 점수가 낮았다. 다변량 로지스틱 회귀분석 결과 회복탄력성 중 자기조절능력(OR, 0.911 ; 95% CI, 0.854-0.971, p=0.004)이 낮을수록 내시경 점막하 박리법 시술 후 겪는 통증이 큰 것으로 나타났다. 결 론 본 연구 결과 내시경 점막하 박리법을 시술 받는 환자의 회복탄력성 하위 항목인 자기조절능력이 낮을수록 시술 후 더 큰 통증을 호소하는 것을 확인하였다. 따라서 본 연구에서 대상으로 한 심리적 요인 중 개인의 회복 탄력성이 통증에 영향을 주는 것을 확인하였다. Objectives : Since pain in cancer patients is an important factor that greatly affects the quality of life and prognosis, many attempts have been actively made to reduce the pain. Despite continuous effort on reducing pain after Endoscopic submucosal dissection (ESD), research has not been done on psychological factors as much as on biological factors affecting pain. The objective of this study is to investigate the psychological factors affecting postoperative pain in gastric tumor patients who underwent gastric ESD. Methods : 91 gastric tumor patients who visited National Health Service Ilsan Hospital in Korean between May 2015 and June 2016, and received ESD were evaluated. Baseline characteristics including sociodemographic factors, anxiety, depression, and resilience were evaluated before the procedure. Multivariate logistic regression was done to analyze factors affecting postoperative pain. Results : The group with high postoperative pain showed lower alcohol consumption and higher depressive symptom scores than the group with low postoperative pain. Also, the group with high postoperative pain showed lower total resilience score with lower subtotal scores in self-control and positive item. Multivariate logistic regression analysis of the postoperative pain showed that patients with lower score in self-control of resilience [odd ratio (OR), 0.911 ; 95% CI, 0.854-0.971, p=0.004) reported more pain after ESD. Conclusions : This study showed that patients with lower self-control ability of resilience felt more pain after ESD. Among the psychological factors evaluated in this study, resilience of an individual seems to have effect on pain.

곰팡이 센서(Fungal detector)를 이용한 알러지 환자 가정의 실내 환경 평가 - 사례연구

The indoor environmental condition was assessed in houses with allergy (asthma and atopy) patients by use of a fungal detector. The fungal index was calculated from the growth rate of the sensor fungi in a fungal detector encapsulating the spores, Alternaria alternata S-78, Eurotium herbariorum J-183 and Aspergillus penicillioides K-712. Fungal indices were higher in asthma patient's houses than in control houses and Eurotium herbariorum showed the highest growth response among the sensor fungi. Dust mites allergen, Der f1, was also significantly high in allergy patient's houses where fungal indices above 10 were detected. A correlation was observed between the fungal indices and dust mite allergen proliferations in examined houses. Therefore, the fungal index can be a useful tool as an indirect indication for detecting chronic dampness that brings both contaminations by fungi and dust mite.

Purpose In deep vein thrombosis test, 180sec latency test, one of existing test methods, has less accuracy of diagnosis because the image of venous thrombosis may be shown differently according to the status of cardiac output, artery occlusion, etc. thus in the present study, an attempt was made to look into the clinical availability of the new test method of performing test at the peak of a time-threshold curve for popliteal veins by using tracker method of multi-detector computed tomography. Materials and methods A retrospective study was made for total 32 patients consisting of 16 patients who took the existing test and 16 patients who took the new test among patients who visited the hospital between May and July 2008 and took deep vein thrombosis test. Using tracker method of the new test method, threshold was set to be high for popliteal veins, and tracking was started 50 seconds after beginning angiography, and when the tracking time curve started to bend downward from the peak of the threshold, test was done together with injection of a cell line in order to reduce arteriography. After test, comparison on the images between existing test method and new one was made and they went through statistical analysis, and based on these, the availability of those images in deep vein thrombosis test was evaluated. Results For thrombosis parts of total 32 patients who took deep vein thrombosis diagnosis, in existing test group, they were mainly found in large blood vessels of the pelvis and abdomen by order of iliac veins, femoral veins, and popliteal veins, while in new test group, they were equally found in popliteal veins, iliac veins, and femoral veins. This result implies that the existing test method has limitations in identifying the extent of the proximal portion for venous thrombosis according to the patient’s cardiac output, artery occlusion, etc. On the other hand, it was pointed out that the new test method showed a highly contrast-enhanced image of arteries, but the quality of image of venous phase could be raised by injection of a cell line. As a result of analysis by statistics of independent sample t-test between existing test group and new test group, a significance level was shown to be(p<0.05)p=0.008, which indicates there was statistically significant difference. Conclusion In the new test method, significantly high incidence of thrombosis was found with development of multi detector computed tomography, thus the new test method is deemed as more useful method in terms of objectivity and accuracy of diagnosis, compared to the existing test method. It is concluded that more prospective studies are required to be made for establishment of protocol with many cases.

The study reviewed issues in the reform of the medical care system for the elderly in Japan. The medical expenditure for the elderly is increasing rapidly with the progress of aging society in Japan. The medical expenditure for the elderly aged 70 and over is already taking 1/3 of national health expenditure. In order to realize fair sharing of the medical expenditure for the elderly by all citizens and contain the increasing of the medical expenditure for the elderly, it is necessary to improve the efficiency of the medical care system for the elderly and to balance the burden on the nonelderly and the elderly. The Japanese Government have implemented the reform of medical care system which involving the reform of the medical care system for the elderly since the mid of 1990"s. The main contents of the reform of the medical care for the elderly are that co-payment for patients is the fixed rate of 10%, the eligible age range is age 75+, and the structure of financial sharing between the contribution of health insurers and public fund is changed, especially toward increasing public fund, to achieve fair cost sharing of medical care for the elderly.
