Overcrowding of emergency department is a serious and growing problem at St. Mary's Hospital. This has motivated the development of short-stay unit(SSU) as an alternative ward to routine hospital admission and ED discharge. In our hospital a SSU begun to admit patients in January 6, 1997. the SSU received 247 patients from the ED during the eight month interval(January 6, 1997 to August 31, 1997). To examine the utilization of the SSU in ED, we retrospectively analyzed 247 patients admired in SSU from the ED, and compared the average hours per patient with acute gastroenteritis spent in the ED doing the 2-month intervals before(July-August 1996) and after(July-August 1997) the establishment of the SSU. The following results were obtained; 1. The total patients consist of EM 92(37.2%), GS 48(19.4%), IM 24(9.7%), PS 21(8.5%), OS 20(8.1%), OBGY 14(5.7%) and others 28(11.3%). 2. The results of EM patients admitted in SSU from ED 1) Sex ratio of male to female was 1:1.1 and the mean age was 37.3+/-16 years. 2) In diagnosis, acute gastroenteritis was 29 cases(31.5%), multiple contusion 14 cases(15.2%), drug intoxication 12 cases(13%), limb laceration 6 cases(6.5%), tendon rupture offhand 6 cases(6.5%), and others 19 cases(20.6%). 3) Mean length of stay in ED was 9.18 hours. 4) Among 92 patients to the SSU, 79 patients(85.9%) were discharged, 11 patients(11.9%) formally admired to hospital and 2 patients(2.2%) transferred to otherhospital. The mean hospital stay time of the patients admitted to SSU was 2.6 days. 3. There was a significant reduction in the average stay time spent in the ED by treat-and-releasing patients with acute gastroenteritis after the establishment of the SSU(from 14.65+/-9.6 to 7.52+/-5.4 hr/patient, p<0.001). Conclusively, the establishment of the SSU can shorten the average stay time that treat-and-releasing patients spend in the ED, and reduce the number of admixed patients waiting in the ED.

BACKGROUND: With increase in the prevalence of obesity in recent years, much inferest has focused on obesity nowdays. Inerease in abdominal fatness raises mortality and morbidity of cardiovascular disease and there is some possibility that smoking has effect on obesity. We evaluated the influence of smoking on abdominal fatness. METHOD: This study was carried out on 475 individuals who visited the Health Promotion Center in Youngnam University Hospital in May, 1999. The subjects were checked on age, sex, life style (smoking, drinking, physical activity, exercise, etc.), past medical history, blood pressure, height, weight, waist circumference, hip circumference, body fat percent and other obesity indexes. RESULTS: In men, waist circumference (P<0.01), body fat percent (P<0.05), waist hip ratio (p<0.01) were significantly increased according to the amount of smoking after adjustment for BMI, age, alcohol intake, exercise and physical activity. But, the waist circumference, waist to hip ratio and percent body fat of mild smoker were rather shorter than that of the non-smoker or one who abstained from smoking. CONCLUSION: In men, it seems that obesity index of abdominal fatness may be significantly high in moderate to heavy smokers and low in mild smokers.

BACKGROUND: The end-tidal carbon dioxide tension(ETCO2) is defied as a partial pressure of carbon dioxide at the end of an exhaled breath.)he purpose of this study is to determine the correlation between ETCO2 and arterial carbon dioxide tension(PaO2) in nonintubated abated patients with respiratory distress in emergency department(ED). METHODS: A prospective non-blind study was performed in ED of our university hospitals. Participants included all nonintubated adult patients with respiratory distress requiring arterial blood gas analysis. ETCO2 was measured with a capnography monitor during tidal volume breathing. ETCO2 were recoreded at the time of arterial blood gas sampling. The correlation between ETCO2 and PaCO2 was analysed in all patients and in subgroups by simple linear regression. RESULTS: Sixty patients were enrolled. In all patients, ETCO2 was 5.72mmHg lower than PaCO2 and correlated well with PaCO 2(r2=0.716). ETCO2 correlated best with PaCO2) in patients who were either acidotic or non-smoking. CONCLUSION: ETCO2 correlate well with PaCO2 in nonintubated patients with respiratory distress in ED. ETCO2 may be sufficient to reflect PaCO2 in selected patients and obviate the need far repeat arterial blood gas determination.

The Korea National Health and Nutrition Examination Survey (KNHANES) is a national program designed to assess the health and nutritional status of the noninstitutionalized population of South Korea. The KNHANES was initiated in 1998 and has been conducted annually since 2007. Starting in the latter half of 2008, ophthalmologic examinations were included in the survey in order to investigate the prevalence and risk factors of common eye diseases such as visual impairment, refractive errors, strabismus, blepharoptosis, cataract, pterygium, diabetic retinopathy, age-related macular degeneration, glaucoma, dry eye disease, and color vision deficiency. The measurements included in the ophthalmic questionnaire and examination methods were modified in the KNHANES IV, V, and VI. In this article, we provide detailed information about the methodology of the ophthalmic examinations in KNHANES in order to aid in further investigations related to major eye diseases in South Korea.

PURPOSE : The aim of this study was to validate the effect and the feasibility of induction chemotherapy in patients with locally advanced non-small cell lung cancer (NSCLC) on multimodality treatment. MATERIALS AND METHODS : From January 2002 to December 2003, 84 chemonaive patients with Stage III NSCLC, median age of 64 years, ECOG perfomance satus 0, 1, or 2, and without other comorbid disease were enrolled this study and received chemotherapy every 3 weeks. After two or three cycles of induction chemotherapy (gemcitabine with cisplatin), patients were reevaluated by chest CT and then underwent resection, radiotherapy, further chemotherapy, or observation. RESULTS : Overall clinical responses were seen in 43 (57%) of the 76 assessable patients. Response rates were 61% and 53% in patients with stage IIIA and IIIB disease, respectively. Twenty-eight patients out of initially unresectable 70 patients (19 of 32 stage IIIA and 9 of 38 stage IIIB) after induction chemotherapy seemed to be resectable. Operation was done in 23 out of 32 patients who achieved clinically resectable stage after induction chemotherapy and 20 (87%) resections were complete and 3 were incomplete including 1 case of open & closure. Thirty-two patients were treated with chest radiation after chemotherapy. Eighteen patients were treated with chemotherapy upto 6 cycles and 6 patients refused further treatment after induction chemotherapy. Median follow up of all patients was 16.2 months, median survival was 16 months, and estimated disease progression free interval was 11 months. Survival and disease progression free interval were different with between induction chemotherapy followed by complete resection subgroup and followed by radiation therapy subgroup (24 vs. 14 months, p=0.04). Grade 3/4 neutropenia and thrombocytopeina were noticed in 29% and 10%, respectively and one chemotherpy related death was also noticed. CONCLUSION : Induction chemotherapy followed by surgery with or without adjuvant radiation might be the recommendable management to improve the survival in locally advanced NSCLC with feasible toxicity

PURPOSE: The aim of this study is to report on preliminary data regarding the prevalence of major eye diseases in Korea. METHODS: We obtained data from the Korea National Health and Nutrition Examination Survey, a nation-wide cross-sectional survey and examinations of the non-institutionalized civilian population in South Korea (n = 14,606), conducted from July 2008 to December 2009. Field survey teams included an ophthalmologist, nurses, and interviewers, traveled with a mobile examination unit and performed interviews and ophthalmologic examinations. RESULTS: The prevalence of visual impairment, myopia, hyperopia and astigmatism in participants over 5 years of age was 0.4 +/- 0.1%, 53.7 +/- 0.6%, 10.7 +/- 0.4%, and 58.0 +/- 0.6%, respectively. The prevalence of strabismus and blepharoptosis in participants over 3 years of age was 1.5 +/- 0.1% and 11.0 +/- 0.8%, respectively. In participants over 40 years of age, the prevalence of cataract, pterygium, early and late age-related macular degeneration, diabetic retinopathy and glaucoma was 40.2 +/- 1.3%, 8.9 +/- 0.5%, 5.1 +/- 0.3%, 0.5 +/- 0.1%, 13.4 +/- 1.5%, and 2.1 +/- 0.2%, respectively. CONCLUSIONS: This is the first nation-wide epidemiologic study conducted in South Korea for assessment of the prevalence of eye diseases by both the Korean Ophthalmologic Society and the Korea Center for Disease Control and Prevention. This study will provide preliminary information for use in further investigation, prevention, and management of eye diseases in Korea.
