To determine the prevalence and risk factors of hypertension we performed cross-sectional study in a rural area. We measured BP and body mass index(BMI), and interviewed adult residents over 30-year-old age. 337 males and 357 females participated the survey. BP was checked twice and the mean was used to determine age and sex specific mean BP and prevalence of hypertension. Prevalence of definite hypertension(BP>or=160/95 or on medication) was 14. 0% in males and 17. 7% in females. Risk factor for hypertension was analysed by multiple logistic regression; age (10years: OR=l. 7) and BMI(1 BMI unit: OR=l. 2) were positively associated with hypertension but smoking(1 pack year: OR=0.9) was shown to have inverse relationship.

The heterotopic and tissues may be divided into two categories: those that are found in the head and neck region, and those that arise elsewhere. The latter type is rare and most cases are found in the lungs of patients with neural tube defect, particularly anencephaly. Our report descrives anencephalic male infant with heterotopic glial nodules in both lungs. The largest nodule is 2x1.5x1 cm, locates in the lower lobe of the left lung, and has a round gray-white cut surface with cystic spaces. Microscopically, the nodules consist of irregularly arranged astrocytes and glial fibers, in which are embedded gland-like or cystically dilated bronchioles. The astrocytes and glial fibers are strongly positive for glial fibrillary acidic protein and show astrocytic filaments on electron microscopy. This will be an additional case supporting the amniotic fluid aspiration/implantation theory of pathogenetic mechanism of distal heerotopic glial tissue.

PURPOSE: Due to remarkable developments in technology and great efforts made by Health Organizations, most of infectious diseases had been under control. However, ecological changes and biological variations resulted in emerging and re-emerging infectious diseases, which threaten the global health and may have the possibility of being abused as biological weapon. Therefore it is indispensable to understand the latest information and knowledge in order to cope with the emergency situation. RESULTS: In Korea, several reemerging diseases such as Malaria, Hepatitis A, Shigellosis, Mumps, and food poisoning has been increasing conspicuously since 1990. Also Diphtheria, plague, yellow fever and dengue fever have been potential threats, considering substantial international trades. CONCLUSION: There have many newly emerged and re-emerged infectious diseases identified in recent few decades in Korea. Thus as epidemiologic professionals, we have to get ready, particularly following missions to be carried out : 1) to keep eyes open to look for emerging and reemerging diseases continuously and keep up the latest global information, 2) establish the co-operational organizations to prepare immediate action against the sudden outbreak, 3) publicize, educate, establish and perform the missions, taking initiative in training clinicians, 4) upgrade professional competency by familiarizing ourselves with epidemiologic investigations, and 5) fulfill the responsibilities as health keepers of the nation.

PURPOSE: The purpose of this study was to compare differences in the time when bowel sounds were heard and gas was passed in women who had an abdominal hysterectomy and were treated for 5 minutes (experimental group A) or 10 minutes (experimental group B) with San-Yin-Jiao (SP-6) acupressure. METHOD: The design of this study was a nonequivalent control group non-synchronized post test only design. The participants included 142 women, 39 in experimental group A, 30 in experimental group B, and 73 in the control group. Data was collected using a structured questionnaire which included items on general characteristics and a self report of time when gas was passed. Differences for the three groups as to time when bowel sounds were heard and gas was passed were analyzed using ANOVA. RESULT: The time when bowel sounds were heard was statistically significantly shorter in both experimental groups compared to the control group(F=10.29, p=.000). The time when gas was passed was statistically significantly shorter in experimental group B(10 min) compared to the control group(F=4.68, p=.011). CONCLUSION: It could be concluded that SP-6 acupressure of 10 minutes was effective in shortening the time until bowel sounds were heard and gas was passed for women who had had an abdominal hysterectomy. Replication of the study with a larger number of participants is necessary in order to be able to generalize the results.

Emergency department (ED) triage systems are used to classify the severity and urgency of emergency patients, and Korean medical institutions use the Korean Triage and Acuity Scale (KTAS). During the COVID-19 pandemic, appropriate treatment for emergency patients was delayed due to various circumstances, such as overcrowding of EDs, lack of medical workforce resources, and increased workload on medical staff. The purpose of this study was to evaluate the accuracy of the KTAS in predicting the urgency of emergency patients during the COVID-19 pandemic. Methods This study retrospectively reviewed patients who were treated in the ED during the pandemic period from January 2020 to June 2021. Patients were divided into COVID-19–screening negative (SN) and COVID-19–screening positive (SP) groups. We compared the predictability of the KTAS for urgent patients between the two groups. Results From a total of 107,480 patients, 62,776 patients (58.4%) were included in the SN group and 44,704 (41.6%) were included in the SP group. The odds ratios for severity variables at each KTAS level revealed a more evident discriminatory power of the KTAS for severity variables in the SN group (P<0.001). The predictability of the KTAS for severity variables was higher in the SN group than in the SP group (area under the curve, P<0.001). Conclusion During the pandemic, the KTAS had low accuracy in predicting patients in critical condition in the ED. Therefore, in future pandemic periods, supplementation of the current ED triage system should be considered in order to accurately classify the severity of patients.

Background: While hypothyroidism is associated with negative health effects in the general population, older adults with hypothyroidism have better physical function and comparable rates of depression and cognitive impairment relative to their euthyroid counterparts. The aim of this study was to investigate the association between thyroid status and health-related quality of life in Korean older adults. Methods: In this population-based cross-sectional study, 1,060 adults aged over 60 years were classified by thyroid status into four groups based on their thyroid stimulating hormone (TSH) and free T4 values: overt hypothyroid, subclinical hypothyroid, euthyroid, and subclinical hyperthyroid. The main outcome measure was self-reported health-related quality of life based on the three-level version of the EuroQol-5 dimension (EQ-5D), with utility values of -0.171 and 1.000 corresponding to the worst and best health statuses, respectively. The adjusted means of the EQ-5D three-level version utility values according to thyroid status were determined using a linear regression analysis. Results: In the adjusted analysis, the overt hypothyroid group showed significantly higher EQ-5D three-level version utility values than did the euthyroid group (0.998 vs. 0.908, P=0.000). In the subgroup analyses by sex, the overt hypothyroid group also showed significantly higher EQ-5D three-level version utility values for both men and women than did the euthyroid group (0.998 vs. 0.940, P=0.008; 0.983 vs. 0.882, P=0.001). Conclusion Asymptomatic Korean older adults aged over 60 years with TSH and free T4 values corresponding to overt hypothyroidism have better health-related quality of life than their euthyroid counterparts.

PURPOSE: Acute aortic diseases, such as aortic dissection and aortic aneurysm, can be life-threatening vascular conditions. In this study, we compared outcomes before and after the implementation of a critical pathway (CP) for patients with acute aortic disease at the emergency department (ED). MATERIALS AND METHODS: This was a retrospective observational cohort study. The CP was composed of two phases: PRE-AORTA for early diagnosis and AORTA for prompt treatment. We compared patients who were diagnosed with acute aortic disease between pre-period (January 2010 to December 2011) and post-period (July 2012 to June 2014). RESULTS: Ninety-four and 104 patients were diagnosed with acute aortic disease in the pre- and post-periods, respectively. After the implementation of the CP, 38.7% of acute aortic disease cases were diagnosed via PRE-AORTA. The door-to-CT time was reduced more in PRE-AORTA-activated patients [71.0 (61.0, 115.0) min vs. 113.0 (56.0, 170.5) min; p=0.026]. During the post-period, more patients received emergency intervention than during the pre-period (22.3% vs. 36.5%; p=0.029). Time until emergency intervention was reduced in patients, who visited the ED directly, from 378.0 (302.0, 489.0) min in the pre-period to 200.0 (170.0, 299.0) min in the post-period (p=0.001). The number of patients who died in the ED declined from 11 to 4 from the pre-period to the post-period. Hospital mortality decreased from 26.6% to 14.4% in the post-period (p=0.033). CONCLUSION: After the implementation of a CP for patients with acute aortic disease, more patients received emergency intervention within a shorter time, resulting in improved hospital mortality.
