Purpose : To determine the optimal scheme of postoperative chemoradiotherapy in rectal cancer by comparing survival, Patterns of failure, toxicities in early and late radiotherapy groups using a Phase III randomized prospective clinical trial. Materials and Methods : From January 1996 to March 1999, 307 patients with curatively resected AJCC stage II and III rectal cancer were assigned randomly to an 'early (151 patients, arm 1)' or a 'late (156 patients, arm II)' and were administered combined chemotherapy (5-FU $375\;mg/m^2/day$, leucovorin $20\;mg/m^2$, IV bolus daily, for 3 days with RT, 5 days without RT, 8 cycles with 4 weeks interval) and radiation therapy (whole pelvis with 45 Gy/25 fractions/5 weeks). Patients of arm I received radiation therapy from day 1 of the first cycle of chemotherapy and those of arm II from day 57 with a third cycle of chemotherapy. The median follow-up period of living patients was 40 months. Results : Of the 307 patients enrolled, fifty patients did not receive scheduled radiation therapy or chemotherapy. The overall survival rate and disease free survival rate at 5 years were $78.3\%\;and\;68.7\%$ in arm I, and $78.4\%\;and\;67.5\%$ in arm II. The local recurrence rate was $6.6\%\;and\;6.4\%$ (p=0.46) in arms I and II, respectively, no significant difference was observed between the distant metastasis rates of the two arms ($23.8\%\;and\;29.5\%$, p=0.16). During radiation therapy, grade 3 diarrhea or more, by the NCI common toxicity criteria, was observed in $63.0\%\;and\;58.2\%$ of the respective arms (p=N.S.), but most were controlled with supportive care. Hematologic toxicity (leukopenia) greater than RTOG grade 2 was found in only $1.3\%\;and\;2.6\%$ of patients in each respective arm. Conclusion : There was no significant difference in survival, patterns of failure or toxicities between the early and late radiation therapy arms. Postoperative adjuvant chemoradiation was found to be a relatively safe treatment but higher compliance is needed.

Objective : This study was to find out the level of sensory process type, adult attachment and interpersonal problems on university students and then to investigate the correlation. Methods : For this study, 169 students who don't know about the evaluation tool in university students of K area in Korea were participated. To execute evaluation, Adolescents/Adults Sensory Profile (AASP) was used for the sensory process type, Short Form of the Korean Inventory of Interpersonal Problems Circumplex Scale (KIIP-SC) was used for interpersonal problems, and Experiences in Close Relationships Scale-Revised (ECR-R) was used for the adult attachment. The correlation between sensory process type and interpersonal problems, adult attachment was analyzed by using pearson correlation analysis. Results : Sensory process type of university students appeared that sensory seeking was lower than general people, and the rest of items showed similar results with general people. For interpersonal problems, there was a lot of difficulty in self-sacrificing and overly accommodating, whereas there was a little difficulty in vindictive and domineering / controlling. For adult attachment, attachment avoiding was more stable than attachment anxiety. Also, low registration and sensory sensitivity all showed positive correlation with interpersonal problems and adult attachment. Among interpersonal problems, self-sacrificing and intrusive showed positive correlation with sensory seeking whereas cold, socially inhibited, nonassertive, and overly accommodating showed positive correlation with sensory avoiding. Thus, sensory seeking and sensory avoiding showed different results (p<.05). Conclusion : In occupational therapy clinic, not only the disabled but non-disabled people that experience issue of interpersonal problems and attachment could be helped with managing high quality social activity if they execute intervention according to sensory process type.

Background: The long-term administration of oral anticoagulant to the patients with a mechanical heart valve prosthesis is mandatory. However, the appropriate intensity of oral anticoagulant therapy to prevent thromboembolic or hemorrhagic complications is still controversial. We tried to apply low intensity anticoagulant therapy for which the International Normalized Ratios ranged between 1.5 and 2.5, and we analyzed the anticoagulation-related long term outcomes. Material and Method: From January 1992 to December 2002, 144 patients who underwent a single cardiac valve replacement were included in the study, and their ages ranged from 15 to 72 years (mean age: $47.4{\pm}15.1$): there were 49 aortic valve replacements (AVR) and 95 mitral valve replacements (AVR). The patients were followed up monthly or bi-monthly at the outpatient clinic with clinical examinations and measuring the prothrombin time to adjust the International Normalized Ratios (INRs) within the low-intensity target range between 1.5 and 2.5. Result: The follow-up period was 835.3 patient-years (mean: $5.9{\pm}3.5$) and the INRs of 7,706 measurements were available for evaluation. The mean INRs of the aortic and the mitral valve replacement groups were significantly different (p<0.01). All the patients' INRs were within the target range in 61.9% of the measurements. The mean INRs $(2.16{\pm}0.23)$ of the patients with atrial fibrillation, which was found in 30.3% of the patients, were definitely higher than those $(2.03{\pm}0.27)$ measured in the patients with regular rhythm (p<0.01). Thromboembolic episodes occurred in 9 patients with an incidence of 1.08%/patient-year. Major bleeding occurred in 2 patients (MVR) with an incidence of 0.24%/patient-year. The patients who displayed better compliance showed a lower incidence of complications (p=0.000). Conclusion: The anticoagulation therapy with a low-intensity target range after MVR or AVR seems to be effective and feasible, and increasing the patients’ compliance should be done for achieving more effective anticoagulation therapy.

Background: Following the implantation of heart valve prostheses, it is important to maintain therapeutic INR to reduce the risk of thromboembolism. The objective of this study was to suggest a practical dosing guideline for Korean outpatients with prosthetic heart valves managed by a pharmacist-run anticoagulation service (ACS). Material and Method: A retrospective chart review was completed for all patients enrolled in the ACS at Seoul National University Hospital from March, 1997 to September, 2000. Patients who were at least 6 months post-valve replacement and had nontherapeutic INR value (less than 2.0 or greater than 3.0) were included. The data on 688 patients (1,782 visits) requiring dosing adjustment without any known drug or food interaction with warfarin were analyzed. The amount of adjusted dose and INR changes based on the INR at the time of the event were calculated. Aortic valve replacements (AVR) patients and mitral or double valve replacement (MVR/DVR) patients were evaluated separately. Result: Two methods for the warfarin dosage adjustment were suggested: Guideline I (mg-based total weekly dose (TWD) adjustment), Guideline II (percentage-based TWD adjustment). The effectiveness of Guideline 1 was superior to Guideline II overall in patients with both AVR and MVR/DVR. Conclusion: The guideline suggested in this study could be useful when the dosage adjustment of wafarin is necessary in outpatients with mechanical heart valves.

Backgrounds : Today, tuberculosis cannot only be cured medically, but also controlled by public health. Despite the overall worldwide decline in tuberculosis, the disease continues to be a significant problem among developing countries and in the slums of large cities in some industrialized countries. Particularly, this communicable disease has come into the public health spotlight because of its resurgence in the 1990's. our country has been operating the Korean National Tuberculosis Control Program since 1962, focusing around public health centers. Therefore, this study aims to compare the effectiveness of tuberculosis control activities, one of the major public health activities in Korea, by producing indexes, such as the yearly registration rate per 100,000 population and treatment compliance of tuberculosis on in small areas (communities). Methods : This work was accomplished by constructing a time-series analytic model using data from "1980~2000: the Yearly Statistical Report" with patient registry data of 234 City. County. District public health centers and by identifying the factors influencing the tuberculosis indexes. Results : The trends of pulmonary tuberculosis positive point prevalence and pulmonary tuberculosis negative point prevalence on X-ray screening have declined steadily, beginning in 1981 and continuing to 1998 by region (city, county, district). Although the tuberculosis mortality rate steadily shows a declining trend by year and region, but Korea still ranks first among 29 OECD countries in 1998, with a tuberculosis mortality rate of 7.1 per 100,000 persons, according to the time-series analysis for fatal diseases. Conclusion : The results of the study will form the fundamental basis of future regional health care planning and the Korean Tuberculosis Surveillance System on 2000. Since the implementation of local autonomy through the Local Health Act of 1995, it has now become vita1 for each city, county, district public health centers to determine its own priorities for relevant health care management, including budget allocation and program goals.

Background : Tuberculous lymphadenitis is one of the most common forms of extrapulmonary tuberculosis. It was recently reported that the treatment for tuberculous lymphadenitis could be shortened to 6 months without increasing the risk of a relapse. However, there is no report of a prospective randomized study on the use of 6-month chemotherapy with HERZ for cervical lymphadenitis, which is regimen recommended in the areas concerned with the initial drug resistance. The aim of this study is to evaluate the efficacy of the 6-month regimen with HERZ for cervical lymphadenitis in areas where there is a high prevalence of drug resistance in Korea. Method : From January 1997 to February 2002, 92 patients with cervical tuberculous lymphadenitis were recruited from Kyungpook national university hospital. Forty-six patients were given the 6-month regimen(2HERZ/4HER) and the other forty-six patients were given the 9-month regimen(2HERZ/7HER). Result : Of the 46 patients given the 6-month regimen, 5 had residual lymph nodes greater than 5 mm after the completion of treatment and 3 had new lymph nodes or an increased lymph node size during the follow-up period. Of the 46 patients in the 9-month regimen, 9 had residual lymph nodes and 8 had new events during the follow-up period. There were no significant differences between the two groups. Conclusion : These results suggest that the 6-month HERZ regimen can be used safely as the initial treatment for tuberculous lymphadenitis in areas with a similar prevalence of drug resistance.

Purpose: Helicobacter pylori infection is known to be associated with acute or chronic abdominal pain and upper gastrointestinal bleeding in children. This study was performed to analyze the gastroduodenoscopic findings and the efficacy of triple therapy with omeprazole, amoxicillin and clarithromycin between one and two weeks of duration in children with H. pylori infection. Methods: We have assessed retrospectively 60 patients presented with acute or chronic abdominal pain or upper gastrointestinal bleeding. H. pylori infection was confirmed by endoscopic biopsy and rapid urease test. Out of 60 patients, 30 patients were treated with a combination of omeprazole, amoxicillin, and clarithromycin for one week, and the other 30 patients were treated for two weeks with the same medication. Efficacy of treatment was assessed 4 weeks after the termination of treatment by using the $^{13}C$ urea breath test. Results: The 60 patients with the complaint of diffuse abdominal pain, epigastric pain, vomiting or hematemesis were included in this study. One-week treatment group (group I) consisted of 30 patients (14 male, 16 female) with mean age of $11.6{\pm}2.67years$. Two-week treatment group (group II) consisted of 30 patients (11 male, 19 female) with mean age of $10.7{\pm}4.17years$. In group I, H pylori were eradicated in 26 out of 30 patients (86.7%). In group II, H. pylori were eradicated in 26 out of 30 children (86.7%). Both groups did $^{13}C$ urea breath test after 4 weeks after termination of the triple therapy. The eradication rates were same in both groups as 86.7%, 26 out of 30 patients in each group. The results of endoscopy were nodular gastritis 26 (43.3%), erosive gastritis 10 (16.7%), hemorrhagic gastritis 7 (11.7%), gastric ulcer 2 (3.3%) and normal finding 15 (25.0%). Conclusion: In this study, the nodular gastritis was most common endoscopic findings with H. pylori positive patients. The eradication rate of H. pylori with omeprazole, amoxicillin and clarithromycin was 86.7% and it would be highly effective as primary treatment with no significant differences in the eradication rate between one-week and two-week treatment groups. However, we should need more long-term follow-up data.

Purpose : To conduct a nationwide survey on the principals in radiotherapy for rectal cancer, and produce a database of Korean Patterns of Care Study. Materials and Methods : We developed web-based Patterns of Care Study system and a national survey was conducted using random sampling based on power allocation methods. Eligible patients were who had postoperative radiotherapy for rectal cancer without gross residual tumor after surgical resection and without previous history of other cancer and radiotherapy to pelvis. Data of patients were Inputted to the web based PCS system by each investigators in 19 institutions. Results : Informations on 309 patients with rectal cancer who received radiotherapy between 1998 and 1999 were collected. Male to female ratio was 59 : 41, and the most common location of tumor was lower rectum ($46\%$). Preoperative CEA was checked in $79\%$ of cases and its value was higher than 6 ng/ml in $32\%$. Pathologic stage were I in $1.5\%$, II in $32\%$, III in $53\%$, and IV in $1.6\%$. Low anterior resection was the most common type of surgery and complete resection was peformed in $95\%$ of cases. Distal resection margin was less than 2 cm in $30\%$, and number of lymph node dissected was less than 12 in $31\%$. Chemotherapy was peformed in $91\%$ and most common regimen was 5-FU and leucovorine ($59\%$). The most common type of field arrangement used for the initial pelvic field was the four field box (Posterior-Right-Left) technique ($65.0\%$), and there was no AP-PA parallel opposing field used. Patient position was prone in $81.2\%$, and the boost field was used in $61.8\%$. To displace bowel outward, pressure modulating devices or bladder filling was used in $40.1\%$. Radiation dose was prescribed to isocenter in $45.3\%$ and to isodose line in 123 cases ($39.8\%$). Percent delivered dose over $90\%$ was achieved in $92.9\%$. Conclusion : We could find the Patterns of Care for the radiotherapy in Korean rectal cancer patients was similar to that of US national survey. The type of surgery and the regimen of chemotherapy were variable according to institutions and the variations of radiation dose and field arrangement were within acceptable range.

This study aimed to develop a planned discharge nursing intervention guideline for patients with pneumothorax, and to examine its influence on drug compliance, knowledge about disease, compliance level with therapeutic regimen, and nursing satisfaction. Methods: The planned discharge nursing intervention guideline was developed based on comprehensive literature reviews and clinical experiences. Patients having video-assisted thoracoscopic surgery at a single general hospital were allocated to either intervention (n=30) or control group (n=29). Participants in the intervention group were administered planned discharge nursing intervention thrice, 30 minutes each, by a cardiovascular nurse. Standard care was provided to patients in the control group. Data were collected from March, 2010 to December, 2010. Results: Participants in the intervention group presented statistically significant improvement in drug compliance (t=-2.05, p=0.044), pill count (t=-2.61, p=0.011), knowledge about disease (t=-4.39, p=0.001), and nursing satisfaction (t=-4.13, p=0.001). No significant difference in compliance levels was observed with standard therapeutic regimen. Conclusion: Planned discharge nursing intervention can be successfully implemented for patients undergoing thoracoscopic surgery. Further research is required to evaluate long-term effects like complication or relapse.

Objectives : The risk of weight gain is high when using antipsychotic drugs, and the prevalence of obesity in people with mental illness is high. Obesity management in psychiatric patients is important because obesity causes various complications and lowers treatment adherence and quality of life. Methods : In this review, we summarized the management strategies for obesity that can occur when using antipsychotic drugs through a web search. Results : Evaluate obesity-related risk factors and related indicators from the beginning of treatment, and conduct regular monitoring. If an antipsychotic drug is used and obesity is induced, a change to a drug with a low metabolic risk may be attempted. Sufficient interventions are also needed on the need to manage obesity, a healthy diet, and exercises in patients and their families. If weight loss is not achieved and obesity-related complications are associated, the use of anti-obesity drugs may be considered. Pharmacological treatment approaches should be carefully considered. Conclusions : Non-pharmacological and pharmacological therapies can be applied to manage weight gain and obesity caused by the use of antipsychotic drugs. When using anti-obesity drugs, the characteristics of mental disorders, drug safety, and drug interactions should be considered.
