PURPOSE: The purpose of this study was to identify the Clusters of health promoting schools in middle and high schools for the Korean Youth Risk Behaviors Web-based Survey. METHODS: The tool of health promoting school was developed based on a framework for action for health promoting schools in World Health Organization and Schools Health Index for middle and high schools in the United States by 2 professionals and 2 health teachers and revised as a result of the preliminary study. Data were collected with a questionnaire from teachers who attended the conference run by Korean Centers for Communicable Disease Control and Prevention in 2009. The data of 363 schools were analyzed using descriptive analysis, t-test, and ANOVA. RESULTS: As a result of comparing the scores of health promoting schools, three Clusters were identified. The Clusters differed significantly in presence of health teacher, location, and type of schools (p<.05). CONCLUSION: These results are a good reference in developing tailored strategies for health promoting schools, which will help improve health-promoting schools.

Twenty-five neonates were observed for the relationship between phenobrbital loading dose, plasma concentrations and control of seizures. Nineteen neonates (76%) had seizures controlled by phenobarbital alone. Effective plasma concentration were 10.0~31.1microgram/ml. Although 14 neonates had seizures controlled by phenobarbital concentration below 20microgram/ml, neonate required level above 30microgram/ml. We found that continued benefit was obtained until phenobarbital plasma concentrations reached 40microgram/ml and there was no adverse effects on cardiorespiratory function. We recommend that plasma phenobarbital concentrations should equal or surpass 40microgram/ml before additional anticonvulsants are used for neonates with seizure.

OBJECTIVES: We investigated the prevalence and functional impairment of premenstrual dysphoric disorder (PMDD) and premenstrual syndrome(PMS) in young women. METHODS: A total of 1063 female college students were recruited from two urban areas(Seoul and Suwon) of Korea. Questionnaires for sociodemographic data and risk factors of PMDD, attitude about menstruation, and the Premenstrual Symptoms Screening Tool(PSST) were applied. RESULTS: The prevalence of severe moderate to severe PMS and PMDD were 16.9% and 11.7%, respectively. There were differences in the alcohol and coffee consumption, severity of menstrual cramp, and family history of PMS among the moderate to severe PMS, PMDD, and no/mild PMS groups. Although some participants did not fulfill diagnostic criteria for PMDD, they showed significant functional impairment. Participants with negative attitude about menstruation reported premenstrual symptoms more frequently than those with positive or ambivalent attitude about menstruation. CONCLUSION: These results suggest that PMS and PMDD were prevalent and associated with functional impairment in young females. Some participants reported significant functional impairments although they did not meet the full DSM-IV diagnostic criteria for PMDD. Negative attitude about menstruation was associated with more premenstrual symptoms experiences.

Bronchiectasis means a permanent abnormal dilatation of one or more large bronchi owing to destruction of theelastic and muscular components of the bronchial wall. Radiological study is the most importat and mandatory procedure. Especially bronchography is essential for the definitive diagnosis of bronchiectasis and for theprecise delineation of the type and extent of the disease. The radiological and clinical findings of 48 cases ofbronchiectasis diagnosed by bronchography and treated at Chosun University Hospital during the 5 years fromJanuary 1980 to Dec. 1984 were analyzed retrospectively. The results were as follows; 1. Among the 48 cases, 34cases(70.8%) were male and 14 cases(29.2%) were female. Peak incidence was in second decade. 2. Chronic cough,productive sputum and hemoptysis are main symptoms and others are chest pain, dyspnea and recurrent bouts ofpneumonia. The most common physical sign is persistent moist rales over the involved area in 23 cases(47.9%).Others are no sign in 17 cases(35.4%), wheezing in 11 cases(22.9%) and digit clubbing in 3 cases(6.3%). 3. Thepresumed causes were composed of not known in 30 cases(62.5%) and complications of measles in 7 cases(14.6%),pertusis in 5 cases(10.4%) and pneumonia in 4 cases(8.3%). Two cases were Kartagener's syndrom and unilateralhyperlucent lung. 4. Plain chest roentgenographic findings were abnormal in 42 cases(87.5%) but normal in 6cases(12.5%). The most common radiological findings was accentuation of lung markings in 36 cases(85.7%) theothers are include in order of frequency; pneumonic infiltration, linear radiolucencies, cystic radiolucencies,decreased affected lung volume air-fluid level and pleural thickening. 5. Bilateral bronchiectasis was demonstrated in 11 cases(22.9%) and the disease was much more often involved left lung than right. The mostcommonly involved lobe is left lower lobe, and the most common site of involvement was the posterior basal segmentof the lower lobe. The type of bronchiectasis is cylindrical in 22 cases(45.8%), varicose in 11 cases(22.9%),saccular in 9 cases(18.8%) and mixed type in 6 cases(12.5%)

BACKGROUND: Alterations in ventricular loading conditions lead to changes in action potential duration via mechanoelectrical feedback. A decrease in load immediately leads to prolongation of repolarization. QT interval and QT dispersion were measured to determine the long-term effect of changes in ventricular systolic load on the ventricular repolarization. METHOD: Corrected QT interval and QT dispersion were measured in 26 patients before and 3-6 months after valvuloplasty for pulmonary stenosis. To determine the effect of ventricular load on ventricular repolarization, patients were divided in 2 groups; Group 1 was those patients with a greater than 30 mmHg and Group 2 was those patients with a less than 30 mmHg decrease in right ventricular systolic pressure. RESULTS: Corrected QT interval (412.6+/-14.5 msec vs 426.4+/-16.8 msec, p < 0.05) and QT dispersion (35.0+/-7.3 msec vs 45.7+/-14..1 msec, p < 0.05)were increased significantly only in Group 1 after vlavuloplasty. CONCLUSION: It suggested that mechanoelectrical interactions are operative for long duration in humans that changes in ventricular load after successful pulmonary valvuloplasty showed long-term effect on the ventricular repolarization.

Esophageal involvement by malignant lymphoma is extremely rare. A case of follicular lymphoma of the esophagus, misdiagnosed as focal lymphoid hyperplasia (pseudolymphoma) in a 72-year-old man is presented. The esophagogram revealed diffuse narrowing of the lumen in the middle and distal portion without ulceration. The resected esophagus showed mural thickening without any remarkable mucosal change. Microscopically, the esophagus showed scattered follicular lymphoid aggregates in the submucosa, extending into periadventitial fat tissue. Most follicles were devoid of germinal center and consisted of loosely aggregated small cleaved cells without atypia. The surrounding stroma of the submucosa showed dense fibrosis entrapping the infiltrating small lymphocytes in a "indian-file" appearance. There were some reactive follicles with germinal center. In the lamina propria, many plasma cells and a few eosinophils were infiltrated. The gene rearrangement study showed rearranged band for Jk probe which confirmed monoclonal B-cell nature of infiltrated small lymphoid cells. The small cleaved lymphocytes arranged in follicles were positive for L26 and bcl-2 protein. This case demonstrated the necessity of immunophenotypic and gene rearrangement study in the diagnosis of pseudolymphoma in the digestive tract.

PURPOSE: This study is exploratory research to check the survey instrument KDSQ-C used to measure cognition for agreement between the elderly and their caregivers. METHODS: Elderly persons from 170 families, who are aged over 65, have never been diagnosed with dementia, and who have caregivers in S City and K City were randomly selected by their nurses. A survey was conducted in the time from September to November, 2009 through personal interviews using a questionnaire. RESULTS: In terms of consistency among items, there was high consistency (0.813) in the responses regarding complex task competence for the statement 'it is hard to reach a destination alone with public transportation'. There was relatively low consistency (0.63) in the responses regard memory for the statement 'they forget an appointment'. When the subject elderly and caregiver live together, as when their children or spouses responded, consistency was greater than when the caregiver lived in a different home. CONCLUSION: KDSQ-C showed high agreement in measurement between the subject elderly and their caregivers, demonstrating that it can be used as a measurement scale for cognition which can be directly applied to the subject elderly.

BACKGROUND: Diagnosis of aortic arch obstruction can be made with two-dimensional and Doppler echocardiography in most cases.However,not infrequently,clear imaging of the aortic arch can not be obtained,particularly in sick neonates and young infants from a number of reasons and heart catheterization and angiography carries significant risk in sick babies.Therefore it is the purpose of this study to assess the feasibility and safety of counter-current aortography through a peripheral artery in young infants and neotates with suspected aortic arch obstruction. METHOD: We studied 56 patients with suspected aortic arch anomaly at Asian Medical Center from Feburary 1990 to April 1997.First choice for the peripheral artery was radial artery on the same side as the aortic arch,followed by brachial artery and axillary artery.Small 24 gauge plastic cannula was inserted and special attention was given to ensure that the peripheral artery,plastic cannula,and a syringe containing contrast material are all in the same plane.1ml/kg of contrast material was injected by rapid hand injection and biplane cineangiograms were taken at 60 frame/second. RESULTS: Fifty six patients underwent 58 angiograms.Age ranged from 5-255 days(median 30 days) and body weight nanged from 2.1-5.4kg(mean3.4kg).There were 27 males and 29 females.Arteries used were:Radial artery in 37,brachal artery in 19,and axillary artery in 2 cases.Peripheral arteries were ipsilateral side as the aortic arch in 54,contralateral side in 2 and bilateral in 2 cases.In 8 patients heart catheterization was done because of inadequate visualization of aortic arch anatomy and/or need for evaluating other defects.In 48 patients who had periperal angiography only,fluoroscopic time ranged from 0.6 to 3.5 minutes and total procedure time ranged from 10 to 15 minutes.Among these 48 patients,only 11 patients(23%) were given intraveous sedation and 37 patients(77%) did not recieve any sedation.Diagnosis of aortic arch anomaly was aortic coarctation in 38,aortic interruption in 10 and nomal aortic arch in 8 patients.Aortic arch anatomy was well demonstrated in all cases where injected artery was on the same side as the aortic arch.In patients who had angiograms through peripheral arteries contralateral to the side of the aortic arch did not haveadequate visualization of the arch.Compression of the carotid artery did not enhance the imaging of the arch.Simultanous bilateral angiography did not improve the imaging quality as compared to ipsilateral artery angiography.Transient complication,related to cannulation,e.g.,prolonged bleeding was seen in only one patient with aortic interruption.Circulation on the upper extremities was normal after angiography in all patients. CONCLUSION: Counter-current aortography using 24 gauge plastic cannular through peripheral artery is feasible,rapid,safe,economic and relatevely non-invasive procedure and provides adquate imaging of aortic arch obstruction in infants and neonates without risk of heart catheterization and angiography.We,therefore,recommend this procedure in selected patients in whom echocardiographic imaging alone is not conclusive for planning corrective sursery.

PURPOSE: This study was to investigate the factors affecting the self-rated health of vulnerable elderly in community. METHODS: The subjects were 2,328 elderly over 65 years who were enrolled in the Visiting Health Care Center in J-gu of S-city from Apr. 2007 to Sep. 2008. Data were collected using questionnaires including general characteristics, health related behavior and health status by nurse at the time of enrollment. The collected data were analyzed by descriptive statistics, test and multivariate logistic regression. RESULTS: 47.2% of the male subjects and 57.2% of the female subjects rated their health "poor". Gender differences were observed in the factors affecting on Self-Rated Health. ADL, depression and the number of diseases played a major role for men, whereas depression, IADL, the number of diseases, ADL, regular exercise and education played a major role for women. These factors explained 17~29% of variance in Self-Rated Health. CONCLUSION: Gender-specific programs for vulnerable elderly may be developed based on this study. Both physical and psychological functions need to be integrated into the programs to improve self-rated health of vulnerable elderly.
