Recent studies showed that air pollution is a risk factor for hospitalization for chronic obstructive pulmonary disease (COPD). However, there is limited evidence to suggest which subpopulations are at higher risk from air pollution. This study was undertaken to examine the modifying effect of specific secondary diagnosis (including hypertension, diabetes, pneumonia, congestive heart failure) on the relationship between hospital admissions for COPD and ambient air pollutants concentrations. Hospital admissions for COPD and ambient air pollution data for Taipei were obtained for the period from 1999-2009. The relative risk of hospital admissions for COPD was estimated using a case-crossover approach. None of the secondary diagnosis we examined showed much evidence of effect modification.

A 15 years Old girl was admitted with chief complaints of intermittent claudication of lower extremity, dizziness, and headache for 5 years. On admission, malignant hypertension was noted in the upper part of body [190-150/120-110] but femoral & dorsalis pedis pulse could not palpate. Once she had experienced C. V. A. due to hypertension of upper part, about years ago. On auscultation, systolic murmur was audible along the left sternal border. E.C.G. Showed left ventricular hypertrophy pattern, and others within normal limit. Retrograde aortography demonstrated diffuse narrowing of entire thoracic aorta with underdeveloped lower abdominal aorta [below the renal artery] & both common lilac artery, and rich collaterals, but normally visualized greater arteries in the aortic arch. On left posterolasteral thoracotomy, entire descending thoracic aorta revealed marked narrowing with mild perivascular adhesion, but no mediastinal pleura adhesion. These findings suggest as congenital type of atypical coarctation in the entire thoracic aorta with mild secondary change. But histopathology was showed the findings of chronic non-specific aortitis, later. Dacron by pass graft was performed with end to side anastomosis between graft and aortic wall. After operation, all her preoperative symptoms & signs were disappeared, and discharged with good general condition.

This study presents the variations on drug utilization for outpatients' URI, gastritis. and hypertension by the type of hospital- tertiary hospital. general hospital. hospital. clinic. It investigated drug expenses. daily drug expenses. days of medication. the highest price of the drugs used. and the number of the different drugs used for each disease and type of hospital. This study also performed analysis to see how much the variations of variables related to drug use affect the variations of drug expenses. The dependent variable was drug expenses and the independent variables were days of medication. the average price of the drugs used. and the number of the different drugs used. Analysis of the drug utilization was performed on NFMI(National Federation of Medical Insurance) 1994 medical expense claim data. Patients with secondary diseases were excluded. In this study. 379 patients with URI, 386 patients with gastritis. 1.257 patients with hypertension were included. It was founded that there were large variation on drug utilization between the types of hospital for same diseases. Days of medication were longest in tertiary hospitals and shortest in hospitals or clinics. Clinics showed the lowest daily drug expenses in all of the diseases investigated. Daily drug expenses were highest in general hospitals or hospitals. which also tended to use drugs of higher price than other types of hospital. General hospitals and hospitals had larger variations in daily drug expenses and the highest price of drugs. It suggested that drug might be utilized overly in general hospitals and hospitals and some other factors might influence on drug utilization in these hospitals. It was found that the variations of drug expenses were affected by the variations of drug price and days of medication rather than the number of the different drugs. Then the strategy to reduce the variations of drug utilization and to improve the quality of drug utilization should focus on the drug price and days of medication. Further study is needed to assess the quality as well as the variation of drug utilization and to show the factors which affect them.

Background/Aims: The association between metabolic syndrome and colorectal cancer (CRC) has been suggested as one of causes for the increasing incidence of CRC, particularly in younger age groups. The present study examined whether the current age threshold (50 years) for CRC screening in Korea requires modification when considering increased metabolic syndrome. Methods: We analyzed data from the National Health Insurance Corporation database, which covers ~97% of the population in Korea. CRC risk was evaluated with stratification based on age and the presence/absence of relevant metabolic syndrome components (diabetes, dyslipidemia, and hypertension). Results: A total of 51,612,316 subjects enrolled during 2014 to 2015 were analyzed. Among them, 19.3% had diabetes, hypertension, dyslipidemia, or some combination thereof. This population had a higher incidence of CRC than did those without these conditions, and this was more prominent in subjects <40 years of age. The optimal cutoff age for detecting CRC, based on the highest Youden index, was 45 years among individuals without diabetes, dyslipidemia, and hypertension. Individuals with at least one of these components of metabolic syndrome had the highest Youden index at 62 years old, but the value was only 0.2. Resetting the cutoff age from 50 years to 45 years achieved a 6% increase in sensitivity for CRC detection among the total population. Conclusions: Starting CRC screening earlier, namely, at 45 rather than at 50 years of age, may improve secondary prevention of CRC in Korea.

Background : Ginseng has traditionally been used in oriental countries to recover vital energy from Qi deficiency, and has shown various biomedical effects in the scientific literature. Recent reports suggest that ginseng could regulate blood pressure (BP), but much controversy still remains. Therefore, we intended to assess the anti-hypertensive effect of several ginseng types frequently used in clinics. We also investigated the anti-hypertensive effect on Koreans and Chinese, and by the body type according to Sasang Constitution Medicine (SCM). Methods : The study subjects were recruited from mildly hypertensive patients who exhibited pre-hypertension(120/80 to 139/89 mmHg) and stage I hypertension (140/90 to 159/99 mmHg) in Korea and China. After assigning the subjects into a Korean, a Chinese, a red, and an American ginseng group by randomization, we prescribed ginseng at a dose of 4.5 g per day for 4 weeks. To assess the anti-hypertensive effect, we compared the mean of systolic and diastolic BP between before and after ginseng medication using a 24-hour ambulatory blood pressure monitor (24 hr ABPM. We also monitored adverse effect and laboratory findings to secure the subjects' safety. In addition, all of the subjects in Korea consulted a specialist of Sasang Constitution Medicine to identify their constitutional type. Results : There were 64 subjects treated with Korean ginseng, 58 treated with Chinese ginseng, 33 treated with red ginseng, and 64 treated with American ginseng. Korean, Chinese, and American ginseng all reduced subjects' BP; Korean and Chinese ginseng showed more effect. The secondary analysis on the subjects' nationality revealed that all of the ginseng types showed more significant anti-hypertensive effect in Chinese patients than in Koreans. The third analysis on the constitutional type of SCM showed there was no significant difference in the effectiveness and the safety of ginseng among the constitutional types. Conclusions : We suggest ginseng, especially Panax ginseng without any steaming-drying process, could be useful for mild hypertension. Further, ginseng is safe regardless of subjects' constitutional type or type of ginseng within a dosage of 4.5g per day.

Background and Purpose : Hypertension is one of the modifiable risk factors for stroke. Lowering blood pressure is a primary or secondary preventative measure for stroke. This study aims to assess the efficacy of Chunghyul-dan(Qingxue-dan) in stage 1 hypertensive patients who have suffered a stroke by 24 hour ambulatory blood pressure monitoring(24ABPM). Subjects& Methods : We enrolled 40 hospitalized stroke patients with stage 1 hypertension and divided them into 2 groups by stratified randomization; group A took 1200mg of Chunghyul-dan(Qingxue-dan) at 8:00 a.m. for two weeks without changing herbal medicine, and group B was the control group. 28 patients were included in the final analysis(15 in group A. 13 in group B). Blood pressure is monitored from 8:00 am to 7:30 am every 30 minutes for 24 hours. Blood pressure was monitored two times at baseline and again two weeks later. We used 3 parameters for evaluating the efficacy of Chunghyul-dan(Qingxue-dan); The first parameter is change from baseline to two weeks later in blood pressure and pulse rate. The second parameter is the trough/peak ratio(TPR) and smoothness index(SI). The third parameter is antihypertensive rate by antihypertensive efficacy guideline. Results : There is no significant difference in the baseline assessment hetween the two groups. Systolic blood pressure $(141.37{\pm}8.96\;mmHg\;vs\;132.28{\pm}9.46\;mmHg)$ decreased after two weeks of 1200mg(P=0.03) intake of Chunghyul-dan(Qingxue-dan). Systolic TPR and SI was 0.87 and 1.04 in group A. Antihypertensive rate was higher in group A. Conclusion: These results suggest that 1200mg doses of Clunghyul-dan(Qingxue-dan) is an effective antihypertensive agent on stage 1 hypertension patients who have suffered a stroke.
