PURPOSE: The purpose of this study was to identify the health behaviors by a risk level of metabolic syndrome (MS) among petty merchants in traditional markets. METHODS: The data were collected through questionnaires and physical examination on abdominal circumstance, triglyceride, HDL, blood pressure, and FBS of 177 subjects in S city, Korea. The data were analyzed by descriptive statistics, chi2-test (or fisher's exact test) and ANOVA using SPSS/WIN 18.0 program. RESULTS: The prevalence of MS was 15.8%, and risk group was 72.9%. The abdominal circumstance and triglyceride levels were higher in MS group than those of the risk group and normal group. The HDL and systolic blood pressure levels were also higher in MS group than those of the normal group. CONCLUSION: The prevalence of MS and risk groups was high among petty merchants in traditional markets. However, these merchants did not practice health behaviors nor take institutional health management benefit. Therefore, governmental level community based health management services are requested for them.

OBJECTIVES: To understand the relationship between monthly household income and number of remaining teeth as an indicator of oral health, and to find the differences between middle-aged and older people in this respect. METHODS: This study was conducted on data extracted from the Korean National Health & Nutrition Examination Survey, which surveyed all Korean citizens in 2012. From these data, data of 4502 people about 40 years of age who completed the questionnaires and examination survey were selected and analyzed. This study investigated the main factors affecting the remaining teeth, and analyzed the moderating effect of age on the relationship between income level and remaining teeth. RESULTS: The average number of remaining teeth was 25.17 for middle-aged people and 15.95 for older people, which was significantly different. The number of remaining teeth for middle-aged people showed a significant relationship with income level, education level, and smoking habit. The number of remaining teeth in older people was related to the same factors, along with an additional factor of whether or not they underwent oral examinations. From the interaction analysis conducted to find the moderating effect of age on the relationship between the number of remaining teeth and income level, the number of remaining teeth was more affected by income level in older people than in middle-aged people. CONCLUSIONS: Income level was strongly related to oral health, particularly in older people. Therefore, it can be concluded that an oral health promotion policy is necessary for low-income people, particularly those in the older age group.

BACKGROUND: The aim of the study was to determine prevalence of potential heterogeneous vancomycin-resistant Staphylococcus aureus (h-VRSA) among methicillin-resistant S. aureus (MRSA) isolated in Korea by using Mu-3 agar and to determine the effect of in vitro vancomycin exposure on the resistance. METHODS: MRSAs isolated in 1980-1999 were screened for the presence of VISA or h-VRSA using Mu-3 agar. MIC of vancomycin was tested by NCCLS agar dilution and broth microdilution tests. Suspected h-VRSA were selected by vancomycin-containing media and change of resistance was determined by population analysis. A strain with Mu50 type growth was serially exposed to 8 pg/ml of vancomycin containing media and change of the vancomycin resistance was determined. RESULTS: Among the 455 MRSA isolates, 18 (3.9 %) grew on selective brain heart infusion agar (BHIA), and 354 (77,8%) on Mu-3 agar, 66 (14.5%) with Mu3 type growth and 78 (17.1%) with Mu50 type growth. MIC of vancomycin was 11 pg/ml for some of the isolates when inocula were approximately 10' CFU, but VISA was not present when tested by NCCLS broth microdilution test. Exposure of the isolates to van-cornycin raised the MIC. Serial exposure once to 8 pg/ml of vancomycin resulted in significant decrease of cells susceptible to 8-12 pg/ml of vancomycin. CONCLUSION: VISA was not present among the test isolates, but 34.2% were suspected to be potential h-VRSAs, suggesting possible emergence of VISA if vancomycin was administered prolonged period. It is considered that suitable screening media are vancomycin containing BHIA for VISA and Mu-3 agar for h-VRSA. The isolates showing Mu50 type growth on Mu-3 agar are not always VISA, but rather h-VRSA.

Hand, foot and mouth disease (HFMD) is a highly contagious viral infection affecting young children during the spring to fall seasons. Recently, serious outbreaks of HFMD were reported frequently in the Asia-Pacific region, including China and Korea. The symptoms of HFMD are usually mild, comprising fever, loss of appetite, and a rash with blisters, which do not need specific treatment. However, there are uncommon neurological or cardiac complications such as meningitis and acute flaccid paralysis that can be fatal. HFMD is most commonly caused by infection with coxsackievirus A16, and secondly by enterovirus 71 (EV71). Many other strains of coxsackievirus and enterovirus can also cause HFMD. Importantly, HFMD caused by EV71 tends to be associated with fatal complications. Therefore, there is an urgent need to protect against EV71 infection. Development of vaccines against EV71 would be the most effective approach to prevent EV71 outbreaks. Here, we summarize EV71 infection and development of vaccines, focusing on current scientific and clinical progress.

This study was conducted to analyze the effect of male middle school students'eating school breakfast on their attitudes toward breakfast and school breakfast. In addition, the effect of school breakfast on breakfast-related eating behaviors and academic achievement was investigated. The study subjects were selected from a male middle school located in Gyeonggi-do, Republic of Korea. Breakfast was provided at the school for 7 weeks during the 2nd semester of the year 2006. Two sophomore classes were selected for the experimental study. All the students from one class (n = 34; School Breakfast Eaters) have eaten school breakfast while none of the students from the other class (n = 33; School Breakfast Non-eaters) have done so. About two weeks after the school breakfast service was terminated, questionnaires were distributed to the two classes and the responses were analyzed. The results showed that School Breakfast Eaters had more positive attitudes toward breakfast and school breakfast than School Breakfast Non-eaters. In addition, School Breakfast Eaters perceived the positive effect of eating breakfast on their school life more highly than School Breakfast Non-eaters. However there was no significant difference between the two groups in their breakfast eating behaviors in terms of breakfast skipping when the breakfast service was not available. No significant difference was found between the two groups with regards to math score variation before and after school breakfast service. In conclusion, school breakfast for 7 weeks had positive effects on male middle school students'attitudes toward breakfast and school breakfast, although the effect was not confirmed in their breakfast-related eating behaviors after the school breakfast service was terminated.

BACKGROUND: This study evaluated the effects of family type and sociodemographic factors on medical treatment, health behavior, and subjective health status in Koreans 60 years and older. METHODS: This study was based on data from the 5th Korea National Health and Nutrition Examination Survey (KNHANES), a nationwide health interview survey using a rolling sampling design involving complex, stratified, multistage, probability cluster. Our subjects included those > or =60 years of age (n=1,946) participating in the KNHANES 2010. Family type was categorized into 7 groups according to cohabitation: alone, couple cohabitation (living with a spouse), parent(s) cohabitation (couple living with parent(s)), offspring cohabitation (no spouse, living with offspring), couple offspring cohabitation (couple living with offspring), couple offspring parents cohabitation (couple living with parent(s) and offspring), and others. Logistic regression analyses were used to examine the association of family type and sociodemographic factors with health care. RESULTS: The most common family type was couple cohabitation (38.26+/-1.8%). In this group, the percentage of non-receipt of needed medical care (odds ratio [OR], 0.60; 95% confidence interval [CI], 0.42 to 0.87) and current smoking rate (OR, 0.32; 95% CI, 0.20 to 0.50) were significantly lower than those living alone. Among the sociodemographic charicteristics, male gender, apartment dwelling, high middle household income, 2 member family, education higher than middle school, and possessing own house were associated with good health care behavior. CONCLUSION: This study shows that couples have better health care behavior than other family types, in particular, limited smoking, appropriate medical treatment, and positive subjective health status. Those living alone visit medical clinics less often and have a negative subjective health status.

PURPOSE: Acute lower respiratory tract infections(LRIs) are an important cause of pediatric morbidity and mortality. Causes of acute LRI in infants and children include bacteria, mycoplasma and respiratory viruses. Understanding of the epidemiology, etiology and clinical features of acute viral LRI is essential to improve the methods of prevention, diagnosis and management of these infections. METHODS: Viral etiologic agents and clinical features of acute viral LRI were studied from November 1990 through April 1994 in apparently healthy children. Nasal aspirates were collected from 334 children, who visited or admitted to Seoul National University Hospital due to acute LRI. Viral agents were detected by virus isolation and/or antigen detection by indirect immunofluorescent staining. Medical records of children with proven viral LRIs were reviewe retrospectively. RESULTS: 1) One or more viral agents were identified in 162 cases(48.45%). 2) The pathogens identified were RSV(54.6%), adenovirus(12.8%), parainfluenza virus type 3(12.1%), influenza A virus(8.5%), parainfluenza virus type 1(5.7%), influenza B virus(1.4%), parainfluenza type 2(1.4%) and mixed(two) viruses(3.5%). 3) Mean age was 15 months and acute viral LRIs occurred mostly in the first two years of life(82%). 4) Clinical patterns of viral LRI were pneumonia(45%), bronchiolitis(32%), croup(13%) and tracheobronchitis(2.1%). 5) Forty-three percents of febrile patients had fever of 39 degrees C or more and 44.5% had fever for 5 days or more. 6) Leukocytosis and increased CRP(more than 3+) were detected in 23% and 16%, respectively. 7) The major radiologic features are parahilar peribronchial infiltration, overaeration and consolidation. CONCLUSIONS: We studied the etiologic agents and clinical features of acute viral LRI in apparently healthy children, the results of which may be helpful to the clinicians and further studies are needed for prevention and treatment of acute viral LRI.

OBJECTIVE: To evaluate concurrent validity between the Korean-Ages and Stages Questionnaires (K-ASQ) and the Denver Developmental Screening Test II (DDST II), and to evaluate the validity of the K-ASQ as a screening tool for detecting developmental delay of Korean children. METHOD: A retrospective chart review was done to examine concurrent validity of the screening potentials for developmental delay between the K-ASQ and the DDST II (n=226). We examined validity of the K-ASQ compared with Capute scale (n=141) and Alberta Infant Motor Scale (AIMS) (n=69) as a gold standard of developmental delay. Correlation analysis was used to determine the strength of the associations between tests. RESULTS: A fair to good strength relationship (k=0.442, p<0.05) was found between the K-ASQ and the DDST II. The test characteristics of the K-ASQ were sensitivity 76.3-90.2%, specificity 62.5-76.5%, positive likelihood ratio (PLR) 2.41-3.40, and negative likelihood ratio (NLR) 0.16-0.32. CONCLUSION: Evidence of concurrent validity of the K-ASQ with DDST II was found. K-ASQ can be used for screening of developmental delay.

BACKGROUND: Perioperative hypothermia can develop easily during shoulder arthroscopy, because cold irrigation can directly influence core body temperature. The authors investigated whether active warming and humidification of inspired gases reduces falls in core body temperature and allows redistribution of body heat in patients undergoing arthroscopic shoulder surgery under general anesthesia. METHODS: Patients scheduled for arthroscopic shoulder surgery were randomly assigned to receive either room temperature inspired gases using a conventional respiratory circuit (the control group, n = 20) or inspired gases humidified and heated using a humidified and electrically heated circuit (HHC) (the heated group, n = 20). RESULTS: Core temperatures were significantly lower in both groups from 30 min after anesthesia induction, but were significantly higher in the heated group than in the control group from 75 to 120 min after anesthesia induction. CONCLUSIONS: In this study the use of a humidified and electrically heated circuit did not prevent core temperature falling during arthroscopic shoulder surgery, but it was found to decrease reductions in core temperature from 75 min after anesthesia induction.

PURPOSE: To demonstrate the effectiveness of the conservative treatment which was introduced to the extraarticular triplane fractures of the distal tibia. MATERIALS AND METHODS: We reviewed radiographs and medical records of eight patients with extraarticular triplane fractures of the tibia. Four patients were treated with closed reduction and internal fixation and the others with closed reduction and plaster. RESULTS: In all patients, the union of fractures was obtained. Although the physes were closed early, there was no angular deformity or leg length discrepancy. CONCLUSION: In case of extraarticular triplane fracture, except for open fracture or failure of closed reduction, conservative treatment yield good result.
