  • Purpose: Esophageal cancer patients have a difficulty in the intake of meals through the blocked esophageal lumen, which is caused by an ingrowth of cancer cells and largely influences on the prognosis. It is reported that esophageal cancer has a very low survival rate due to the lack of nourishment and immunity as the result of this. In this study a new radioactive stent, which prevents tumor ingrowth and restenosis by additional radiation treatment, has been developed. Materials and Methods: Using ${\ulcorner}HANARO{\lrcorner}$ research reactor, the radioactive stent assembly ($^{166}Ho$-SA) was prepared by covering the metallic stent with a radioactive sleeve by means of a post-irradiation and pre-irradiation methods. Results: Scanning electron microscopy and autoradiography exhibited that the distribution of $^{165/166}Ho\;(NO_3)$ compounds in polyurethane matrix was homogeneous. A geometrical model of the esophagus considering its structural properties, was developed for the computer simulation of energy deposition to the esophageal wall. The dose distributions of $^{166}Ho$-stent were calculated by means of the EGS4 code system. The sources are considered to be distributed uniformly on the surface in the form of a cylinder with a diameter of 20 mm and length of 40 mm. As an animal experiment, when radioactive stent developed in this study was inserted into the esophagus of a Mongrel dog, tissue destruction and widening of the esophageal lumen were observed. Conclusion: We have developed a new radioactive stent comprising of a radioactive tubular sleeve covering the metallic stent, which emits homogeneous radiation. If it is inserted into the blocked or narrowed lumen, it can lead to local destruction of the tumor due to irradiation effect with dilatation resulting from self-expansion of the metallic property. Accordingly, it is expected that restenosis esophageal lumen by the continuous ingrowth and infiltration of cancer after insertion of our radioactive stent will be decreased remarkably.

  • The purpose of this descriptive study was to evaluate the clinical validity of QSCCII (Questionnaire for the Sasang Constitution Classification), whose high accuracy as a constitutional diagnostic tool has been recognized by medical professionals. The subjects of this study were 568 clients from an A university hospital in Suwon. Of the subjects, 259 were health center visitors and 292 were ambulatory clinic visitors. Data were collected using self-reported questionnaire and were analyzed by $X^2$-test and one-way ANOVA. The results of this study as follows: 1. In 4 types of constitution, Soeumin type was found in 41.5% of the subjects. Taeumin type in 39.2%.,and Soyangin type in 19.2%, respectively. There was no Tayangin type found in this study. There were no significant differences on types of constitution by demographic characteristics such as age, sex, marital status, education, religion, and economic status. 2. As for 15 item-selective questionnaire, there were statistically significant differences on the response rate of the 12 items, except items such as A4, A11 and A14, by the types of constitution. When the subjects' own criteria on their constitution were compared to the given constitutional criteria on each item, 4 items such as A6, A11, A13 and A14 were advisable to be excluded from the questionnaire or to be reunited to the other criteria. In the meanwhile, 3 items such as A7, A18 and A15 were desirable to be re-categorized to the other constitutional types and reconstructed to the QSCC II questionnaire. 3. In terms of 106 true-false questionnaire, there were statistically significant differences on the response rate of 46 items by the types of constitution. The 46 items include 15 items (32.6%) of the domain of 'handling something/strength and weakness', 4 items (8.7%) of the domain of 'interpersonal relationship', 9 items (19.6%) of the domain of 'state of mind at ordinary times', 2 items (4.3%) of the domain of 'distinctive emotional characteristics' area, 11 items (23.9%) of the domain of 'specific behavioral trait' and 5 items (10.9%) of the domain of 'physical characteristics'. Therefore, the areas of 'handling something/strength and weakness' and' specific behavioral trait' mainly contributed to the classification of constitutional type. 4. When the 106 true-false items were simplified to the 46 items, statistically significant differences were found on the rate of items allocated to the 3 types of constitution. The rate of selection assigned to the 3 constitutional types of the simplified 46-item questionnaire was higher than that of the original 106-item questionnaire. Conclusions; It was concluded that the rate of selection of each lay person about his own constitutional type would be still higher even though the simplified items of QSCC II questionnaire were applied. If more replicated studies are conducted on the diverse population using the simplifying QSCC II questionnaire in the future, a more simplified standardized Sasang Constitution Questionnaire that is available to the public rather than to medical staffs in the clinical settings could be developed. Moreover, the simplified scale will help nurses deliver more efficient nursing care by providing a more rapid way of health assessment.

  • Purpose : This study was conducted to assess clinical practices related to the evaluation and treatment of patients with acute gastrointestinal infection(AGI) in infants and children. This survey also evaluated the current opinion regarding the use of rotavirus vaccine. Methods : This survey was conducted using a self-administered questionnaire provided to 82 pediatricians in private clinics of Jeonbuk province. From April to June, 2002, 63 of 82 pediatricians(76.8 %) responded to the survey. Results : The annual proportion of patients with AGI was 13%. The highest proportion of patients with diarrhea were reported for the months of October through December. For the treatment of diarrhea, pediatricians preferred to prescribe lactobacillus products, oral rehydration solution, enzyme products, anti-emetics, anti-diarrheal formula, nothing by mouth(NPO) and bowel movement inhibitors in descending order of frequency. Most pediatricians(79.4%) prescribed antibiotics in less than 20% of patients with AGI. Amoxicillin was the most commonly prescribed antibiotics followed by trimethoprim/sulfamethoxazole(TMP/SMX) and amoxicillin/clavulanate. Clinical manifestations that pediatricians considered as important factors in prescribing antibiotics were bloody diarrhea, mucoid diarrhea, high fever, persisting disease and abdominal pain. Diagnostic procedures that pediatricians preferred for AGI patients were stool examination(rotavirus antigen, RBC, WBC), abdominal X-ray, and serum electrolytes. Pediatricians had a strong interest in rotavirus vaccine(71.4%). Conclusion : Acute gastrointestinal illness remains a common problem, especially during the winter months in Korea. AGI manifesting as watery diarrhea is appropriately treated with commonly available agents but pediatricians appear ready to consider additional approaches to decrease the sizable disease burden of AGI among children in Korea.

  • Background: Breast cancer is the leading cause of cancer deaths among women worldwide. High breast cancer mortality has been attributed to lack of public awareness of the disease. Little is known about the level of knowledge of breast cancer in Central African Republic. This study aimed to investigate the knowledge of health professionals on breast cancer. Materials and Methods: This cross-sectional study was conducted among 158 health professionals (27 medical; 131 paramedical) in 17 hospitals in Bangui using a self-administered questionnaire. Descriptive statistical analysis, Person's ${\chi}^2$ test and ANOVA were applied to examine associations between variables with p < 0.05 being considered significant. Results: Data analyzed using SPSS version 20 indicates that average knowledge about breast cancer perception of the entire population was 47.6%, diagnosis method 45.5%, treatment 34.3% and risk factors 23.8%. Most respondents (65.8%) agreed that breast cancer is important in Central African Republic and that family history is a risk factor (44.3%). Clinical assessments and mammography were considered most suitable diagnostic methods, and surgery as the best treatment. The knowledge level was significantly higher among medical than paramedical staff with regard to risk factors, diagnosis and treatment. However the trainee group had very high significant differences of knowledge compared with all other groups. Conclusions: There is a very urgent need to update the various training programs for these professionals, with recommendations of retraining. Health authorities must create suitable structures for the overall management of cancer observed as a serious public health problem.

  • Objectives: To determine the current status of the treatment of breast cancer patients by Korean Medicine doctors (KMDs) and to examine the need for clinical practice guidelines (CPGs) for the supportive care of these patients. Methods: This cross-sectional study used a self-administered questionnaire. Participants were asked about their experience in treating breast cancer patients; the number of breast cancer patients they currently treat; the main complaints expressed by, diagnoses of, and treatments used for such patients; and their opinions about Korean Medicine (KM) as the basis for providing supportive care for breast cancer. Results: The data for this study were collected from 322 respondents. 84 of whom reported having ever treated patients with breast cancer. Most breast cancer patients who visited the KM clinic were classified as stage I or II, and their major complaints were fatigue, general weakness and musculoskeletal pain. The major diagnostic strategies were syndrome differentiation and pulse diagnosis. The major treatments administered were herbal medicine, acupuncture, and moxibustion. KMDs cited a need for medical information, such as CPGs, as their most important concern with regard to the treatment of breast cancer patients. Conclusions: This survey determined the prevalence of the use of KM for Korean breast cancer patients. Our results underscore the need for clinical practice guidelines for using of KM as the basis of supportive care for breast cancer and for informing clinicians and patients about this approach.

  • Background: Spontaneous pneumomediastinum is an uncommon, benign, self-limited disorders that usually occurs in young adults without any apparent precipitating factors or disease. The purpose of this study was to review our experience in dealing with this entity and describe a reasonable course of assessment and management. Material and Method: A retrospective case series was conducted to identify adults patients with SPM who were diagnosed and treated in a single institution between 2001 and 2005. Result: Fifteen patients were identified who included 14 men and 1 women with a mean age of 26 years. Presenting symptoms were chest pain in 12 patients ($80\%$), dyspnea in 5 patients ($33\%$), and throat discomfort in 4 patients ($26\%$). Two cases were associated with use of inhalational drugs and 3 cases were associated with exercise. The predisposing factors were asthma, excessive exercise, and vomiting in spontaneous pneumomediastinum. The physical findings were subcutaneous emphysema in 10 patients ($77\%$). Chest radiography and computerized tomography were the diagnostic methods in all cases with CT scan revealing six cases with associated pulmonary abnormalities. Esophagogram and flexible bronchoscopy were selectively used. Fifteen patients ($100\%$) were admitted to the hospital. Their mean hospital stay was 3 days. All patients were conservatively treated. In a follow-up of 3 years no complications or recurrences were observed. Conclusion: Most simple spontaneous pneumomediastinum cases were benign diseases and most of them ($77\%$) had shown typical chest pain, dyspnea and subcutaneous emphysema. Inhalational drug use was not a major cause of SPM; however, increased use of bronchoinhalers was a suspicious cause of SPM.

  • Dementia is major epidemic disease of the 21st century in the world. Dementia is one of the major issues in public health globally. Also in Korea, the estimated prevalence of dementia was 8.7%(0.47 million) in 2010, the number will reach the 1 million mark in 2024, it will become a 15.1%(2.71 million) by 2050. Among Koreans aged 65 or older, 725,000 are estimated to be suffering from dementia in 2017. Against dementia, Korea developed three National Dementia Plans in 2008, 2012, and 2016. The 1st plan was came into effect in 2008 and focused on prevention, early diagnostic, development and coordination of infrastructures and management, and improving awareness. The 2nd plan was launched in 2012, addressed the same priorities but had a stronger focus on supporting family members. In 2012 the Dementia Management Act established a statutory basis for organization of the National Dementia Plans. Under the Dementia Management Act, the government is required to produce a comprehensive plan for dementia every 5 years. The Act also orders that the government should register the dementia patients and collect statistics on epidemiology and the management of the dementia conditions. The Dementia Management Act of Korea required the operation of the National Institute of Dementia and Metropolitan/Provincial Dementia Centers to make and carry out dementia management plans throughout the nation. The Act also mandate to establish Dementia Counselling Centers in every public health center and the National Dementia Helpline. The 3rd National Dementia Plan of 2016 aims to build a dementia friendly community to ensure people with dementia and their carer live well. This plan focus on community-based prevention and management of dementia, convenient and safe diagnosis, treatment, and care for people with dementia, the reduction of the care burden for family care-givers of people with dementia, and support for dementia research through research, statistics and technology. In 2017, Moon's government will introduce the "National Dementia Responsibility System," which guarantees most of the burden caused by dementia. This plan include that the introduction of a ceiling on self-pay for dementia diseases, expansion of the application of dementia care standards through alleviating the support criteria for long-term care insurance for mild dementia, expansion of dementia support centers, expansion of national and public dementia care facilities. In the meantime, Korea has accomplished many accomplishments by establishing many measures related to dementia and promoting related projects in a short time, but there are still many challenges.

Association between Risk of Obstructive Sleep Apnea and Subjective Health and Health-Related Quality of Life of the Korean Middle-Aged and Elderly Population (한국 중고령층의 폐쇄성 수면무호흡증 위험과 주관적 건강 및 건강 관련 삶의 질 간의 연관성)

  • Background: This study aimed to identified the relationship between the risk of obstructive sleep apnea, subjective health, and health-related quality of life among the middle-aged and elderly population in Korea. Methods: Adults aged 40 or older were extracted from the total 22,559 respondents to the 2019-2020 Korea National Health and Nutrition Examination Survey VIII, and secondary analysis was conducted on a total of 6,659 middle-aged and elderly people with no missing values. Logistic regression analysis and multiple regression analysis were conducted to examine the relationship between obstructive sleep apnea risk factors and subjective health as well as quality of life. Results: The subjective health status decline in the high-risk group compared to the non-risk group for obstructive sleep apnea was statistically significantly higher, with an odds ratio of 1.84 (p<0.001). The health-related quality of life was also statistically significantly lower by 0.02 points (β, -0.02; p<0.001). As a result of subgroup analysis on specific variables, the association between the risk of obstructive sleep apnea and subjective health and health-related quality of life was statistically significant depending on gender, sleep time, presence of depression, household income, and number of household members. Based on the obstructive sleep apnea risk group, women had a higher correlation with low subjective health and lower health-related quality of life scores than men. Sleeping time of more than 8 hours or less than 6 hours was more associated with low subjective health and lower health-related quality of life score than sleeping time of 6-8 hours. Patients with depression were more likely to have low subjective health than those without depression. The lower the household income level and the smaller the number of household members, the higher the association with low subjective health and the lower the health-related quality of life score. Conclusion: It is essential to recognize that the risk of obstructive sleep apnea not only directly affects sleep disorders but also impacts individuals' subjective health and quality of life. Consequently, social support and education should be provided to raise awareness of this issue. Particularly, programs for preventing and managing obstructive sleep apnea should target vulnerable groups such as women, individuals in single-person households, low household income, and those with depression, aiming to improve their subjective health and quality of life.
