Aim: To assess the treatment outcome in patients with malignant skin melanoma and prognostic factors for distant metastases (DM), disease-free survival (DFS) and overall survival (OS). Materials and Methods: A retrospective analysis was conducted on 113 patients with malignant skin melanoma (60 females, 53 males, average age-55 years) who were treated surgically. Primary treatment consisted of local excision. In 12 cases, it was accompanied by lymph node excision. In 93 (82%) cases, radicalization was necessary, which was either local only (19 cases) or accompanied by lymph node surgery/biopsy (74 cases). Possible prognostic factors such as Clark's stage and Breslow's depth of invasion, ulceration, average tumor dimensions, lymph nodes metastases (pN+), gender, tumor location and primary excision margins were considered. Results: In 51 (45%) cases, treatment failure occurred. The 5-year DM rate was 47%, the 5-year DFS was 38%, and the 5-year OS was 56%. In the univariate analysis, the important factors with respect to at least one endpoint included Clark's stage, Breslow's depth of invasion, ulceration, average tumor dimensions, lymph nodes metastases, gender and primary tumor localization. The presence of metastasic nodes was the most important prognostic factor, with a 5-year DM rates of 30% for pN(-) and 76% for pN(+) and a 5-year DFS and OS of 56% and 76% for pN(-) and 13% and 24% for pN(+), respectively. The average tumor dimension was independently significant for DFS and OS, with 5-year rates of 69% and 80% for ${\leq}1cm$, 28% and 53% for 1-2 cm, and 18% and 30% for >2 cm, respectively. Tumor location was also significant for DM and OS, with 5-year rates of 69% vs 33% and 41% vs 66% for trunk vs other locations, respectively. Conclusions: The natural course of a malignant skin melanoma treated radically is disadvantageous, with unsuccessful outcome in nearly half of the cases. Common clinical factors, such as Clark's tumor stage, Breslow's depth of invasion and the presence of metastatic nodes, have high prognostic significance. The size and location of the primary lesion may be considered independent prognostic factors. The most important negative prognostic factor is the presence of metastatic regional lymph nodes. Only one quarter of patients with metastases in lymph nodes survive 5 years from primary surgery.

Purpose: Continuous renal replacement therapy (CRRT) is becoming the treatment of choice for supporting critically ill pediatric patients. However, a few studies present have reported CRRT use and outcome in neonates weighing less than 3 kg. The aim of this study is to describe the clinical application, outcome, and complications of CRRT in small neonates. Methods: A retrospective review was performed in 8 neonatal patients who underwent at least 24 hours of pumped venovenous CRRT at the Samsung Medical Center in Seoul, Korea, between March 2007 and July 2010. Data, including demographic characteristics, diagnosis, vital signs, medications, laboratory, and CRRT parameters were recorded. Results: The data of 8 patients were analyzed. At the initiation of CRRT, the median age was 5 days (corrected age, $38^{+2}$ weeks to 23 days), and the median body weight was 2.73 kg (range, 2.60 to 2.98 kg). Sixty-two patient-days of therapy were reviewed; the median time for CRRT in each patient was 7.8 days (range, 1 to 37 days). Adverse events included electrolyte disturbances, catheter-related complications, and CRRT-related hypotension. The mean circuit functional survival was $13.9{\pm}8.6$ hours. Overall, 4 patients (50%) survived; the other 4 patients, who developed multiorgan dysfunction syndrome, died. Conclusion: The complications of CRRT in newborns are relatively high. However, the results of this study suggest that venovenous CRRT is feasible and effective in neonates weighing less than 3 kg under elaborate supportive care. Furthermore, for using potential benefit of CRRT in neonates, efforts are required for prolonging filter survival.

목 적 : 최근 신생아 집중 치료의 발달로 인하여 출생체중 1,500 g 미만의 극소 저체중출생아(very low birth weight infants, VLBWI)의 생존율이 높아지고 있다. 이에 저자들은 최근 12년간 한림대학교 강남성심병원 신생아 중환자실에 입원한 극소 저체중 출생아의 치료 결과의 변화를 조사하였다. 방 법 : 1997년 1월 1일부터 2008년 12월 31일까지 한림대학교 강남성심병원 신생아 중환자실에 입원한 1,500 g 미만의 VLBWI 339명을 대상으로 하였고 I기(1997-2003년), II기(2004-2008년)로 나누어 각기별 출생체중과 재태연령의 변화, 생존율, 이환율, 사망원인 및 시기에 대해 병록지 검토를 통해 후향적으로 조사하였다. 결 과 : VLBWI 발생 빈도는 II기에 유의하게 증가하였으며 평균 출생체중 및 재태 연령도 I기에 비해 II기에 유의하게 감소하였으나 1분과 5분 아프가 점수는 II기에 더 높았고(P<0.05), 인공 호흡기 사용기간, 산소 총 투여 기간에는 두 기간사이의 통계적으로 유의한 차이는 없었다(P>0.05). 산모와의 관계를 보면 자궁경부 근무력증, 출생 전 스테로이드 사용, 조기 양막파수는 II기에 유의하게 증가하였다. 생존율에 있어서는 I기에 59.1%, II기에 74.2%로 유의한 증가를 보였으며(P<0.05), 출생체중 1,000 g 미만, 재태연령 28주 미만의 환아의 생존율 증가가 두드러졌다. 극소 저체중 출생아에서 흔히 동반되는 질환으로는 호흡곤란 증후군, 미숙아 망막증, 패혈증, 기관지폐 형성이상, 동맥관 개존증, grade III 이상의 뇌실 내 출혈 및 뇌백질 연화증, 괴사성 장염의 발생은 동맥관 개존증을 제외하고는 두 기간 간의 유의한 차이는 없었다. 사망 원인으로는 호흡곤란 증후군이 가장 많았고 폐출혈, 패혈증이 그다음을 차지하였고, 사망 시기는 두 기간 모두 7일 이내 사망률이 가장 높았다. 결 론 : 최근 12년간 본원에서 출생한 VLBWI의 생존율은 현저히 향상되었으며 특히 1,000 g 미만 28주 미만 환아에서의 생존율 향상이 두드러졌다. 이는 여러 가지 신생아 집중치료술의 향상에 따른 것으로 생각된다. 하지만, 아직 초기 사망율이 높으므로 급성기 치료에 더욱 관심을 갖고 출생체중, 재태연령, 산소치료등과 밀접한 관계가 있는 합병증인 기관지폐 형성이상, 미숙아 망막증 등의 빈도를 줄이기 위해 노력해야 할 것으로 생각된다.

Polyarteritis nodosa (PAN) is a systemic necrotizing vasculitis that typically affects the medium-sized muscular arteries, with occasional involvement of the small muscular arteries. As with other vasculitides, PAN can affect any organ system, including the cardiovascular, gastrointestinal and central nervous systems. The prognosis for patients with untreated PAN is relatively poor, with five-year survival rates of approximately 13 percent. The outcome has improved with proper therapy to approximately 80 percent survival at five years. We report here on a case of a 46 year old man with polyarteritis nodosa and who suffered from pulmonary tuberculosis.

Purpose: Radiotherapy (RT) is considered a mainstay of treatment in parameningeal rhabdomyosarcoma (PM-RMS). We aim to determine the treatment outcomes and prognostic factors for PM-RMS patients who treated with RT. In addition, we tried to evaluate the adequate dose and timing of RT. Materials and Methods: Twenty-two patients with PM-RMS from 1995 to 2013 were evaluated. Seven patients had intracranial extension (ICE) and 17 patients had skull base bony erosion (SBBE). Five patients showed distant metastases at the time of diagnosis. All patients underwent chemotherapy and RT. The median radiation dose was 50.4 Gy (range, 40.0 to 56.0 Gy). Results: The median follow-up was 28.7 months. Twelve patients (54.5%) experienced failure after treatment; 4 local, 2 regional, and 6 distant failures. The 5-year local control (LC) and overall survival (OS) were 77.7% and 38.5%, respectively. The 5-year OS rate was 50.8% for patients without distant metastases and 0% for patients with metastases (p < 0.001). Radiation dose (<50 Gy vs. ${\geq}50Gy$) did not compromise the LC (p = 0.645). However, LC was affected by ICE (p = 0.031). Delayed administration (>22 weeks) of RT was related to a higher rate of local failure (40.0%). Conclusion: RT resulted in a higher rate of local control in PM-RMS. However, it was not extended to survival outcome. A more effective treatment for PM-RMS is warranted.

Purpose: The aim of the present study was to evaluate the clinical outcome of resorbable blasting media surface tapered implant. Methods: 169 Osstem$^{(R)}$ GS III dental implants in 73 patients who received implant treatments at Seoul National University Bundang Hospital, were included in this study. The incidence of biological and prosthetical complications has been carefully analysed for each implant. Results: The short-term implant survival rate was 97.63%, success rate 94.7%. The prevalence of biological complications was 15.38% and the prevalence of prosthetic complications was 13.04%. The mean value of crestal bone loss was $0.28{\pm}0.57$ mm. The relationship between loading periods and marginal bone loss was small and not statistically significant. In mandible, marginal bone loss was larger than in maxilla, no statistically significant. Also, length and diameter of implant had no relationship with marginal bone loss. Conclusion: We suggest that this implant system could achieve successful and stable results.

Purpose: Health Insurance Review & Assessment Service (HIRA) launched an Acute Myocardial Infarction(AMI) assessment for the Payment For Performance(Quality Incentives) Pilot Project from July 2007. Assessment measures of AMI were composed of five process measures and one outcome measure, and each measure was incorporated into one composite quality score to Pay for Performance. Method: For calculation of composite quality score, we considered weighting for the measures using the Delphi method. The questionnaire was composed of three measure groups, 'Reperfusion rate'(Fibrolytic therapy received within 60 minutes of hospital arrival, Primary Percutaneous Coronary Intervention within 120 minutes of hospital arrival), 'Medication prescription rate'(Aspirin at arrival, Aspirin prescribed at discharge, Beta-blocker prescribed at discharge) and 'Survival Index'(30-day mortality rate). Result: A panel composed of 18 and completed a questionnaire by allocation of 10 scores to the three above mentioned measure groups. The Delphi was carried out until three rounds of surveys. In conclusion, each measure group was weighted differently and the 10 scores were allocated as 4.5 to 'Reperfusion rate', 2.5 to 'Medication prescription rate', and 3.0 to 'Survival Index'. Conclusion: The results of this study proposed the calculation method for weighting of Acute Myocardial Infarction quality indicators.

Objective: To evaluate the prognostic factors of gallbladder carcinoma. Methods: Presentation, operative data, complications, and survival outcome were examined for 132 gallbladder carcinoma patients who underwent gallbladder surgery in our unit during 2002-2007, and follow-up results were obtained from every patient for univariate and multivariate survival analysis. Results: The univariate analysis showed that gallbladder lesion history, tumor cell differentiation, Nevin staging, preoperative lymph node metastasis and the surgical approach significantly correlated with the prognosis of the patients (p<0.05). The results of the multivariate analysis (Cox regression) showed that gallbladder lesion history, Nevin staging and the surgical approach were independent predicators with relative risks of 6.9, 4.4, 2.8, respectively (p=0.002, 0.003, 0.008). Conclusion: Gallbladder lesion history, Nevin staging and the surgical approach are independent prognostic factors for gallbladder carcinoma, a rapidly fatal disease. Therefore, early diagnosis, anti-infective therapy and radical surgery are greatly needed to improve the prognosis of gallbladder carcinoma.

Objective: To investigate any association between XRCC1 and XRCC3 polymorphisms and outcome of platinum-based chemotherapy in ovarian cancer patients. Methods: With a prospective study design was cases were consecutively collected from January 2005 to January 2007. All 310 included patients were followed-up until the end of January 2010. Genotyping of XRCC1 and XRCC3 polymorphisms was conducted by TaqMan Gene Expression assays. Results: A total of 191 patients died during follow-up. Our study showed a lower survival rate in XRCC1 399 Arg/Arg genotype than Gln/Gln, with a significant increased risk of death (HR=1.69, 95%CI=1.07-2.78). Similarly, those carrying XRCC3 Thr/Thr genotype had a increased risk as compare to the Met/Met genotype, with a HR (95% CI) of 1.90 (1.12-3.41). There was no significant association between XRCC1 Arg194Trp and XRCC1Arg280His gene polymorphisms and ovarian cancer death. Conclusion: Our study demonstrates that polymorphisms in DNA repair genes have roles in the susceptibility and survival of ovarian cancer patients.

Background : I investigated clinical research methodology of Traditional Korean Medicine(TKM) for treatment of lung cancer with Evidence Based Medicine(EBM) approach. Methods : I conducted the internet search of National Central Library, the National Assembly Library, Korea Education & Research Information Service, Korea Institute of Science and Technology Information for Korean theses and papers, and MEDLINE for the outside articles. Conclusion : In addition to outcomes of clinical trial, abundant clinician's experience and patients' preference are also considered. Pragmatic trials and quasi-experimental trials are better than clinical trials to plan clinical design of TKM for lung cancer and appropriate endpoints includes overall survival, disease-free survival, patient reporting outcome.
