To understand the seroepidemiological patterns of haemorrhagic fever with renal syndrome in Korea, a nation-wide survey collaborated with fourteen clinics was carried out from 1994 to 1996. Sera of 4,547 patients with acute febrile episodes were tested by indirect immunofluorescent antibody test and the seroepidemiological analysis including sex, age, seasonal and regional distributions were performed. According to the results obtained in this study, the epidemiological characteristics of haemorrhagic fever with renal syndrome in Korea were summarized as follows: 1. Seropositive rate of hemorrhagic fever with renal syndrome among the patients with acute febrile episodes was 6.4% by the cut-off point of 1:40. 2. Among the seropositives, male outnumbered female and the ratio of males to females was 2.0:1.0. 3. Seventy six % of the seropositive patients were 21-60 years old. 4. The number of seropositive cases increased from October and reached maximum in December and began to decrease gradually from January. 5. The geographical distribution of the seropositives cover most areas including Cheju province in Korea.

BACKGROUND: Carotid artery stenting (CAS) is emerging as an alternative to carotid endarterectomy for the treatment of carotid stenosis. The effects of CAS on cognitive function have not been fully addressed. The aim of this study was to assess the effect of carotid stenting on cognitive function from baseline to 3 months in patients with severe carotid artery stenosis through the use of a detailed neuropsychological test. METHODS: We recruited 28 patients with carotid artery stenosis (> or =70%) at baseline on a consecutive basis between February, 2009 and December, 2010. Twenty-two patients out of 28 cases, who had undergone CAS and follow-up neuropsychological evaluation after 3 months, were included in our analysis. Main cognitive outcome measures were the Seoul Neuropsychological Screening Battery-Dementia version (SNSB-D), which containing detailed cognitive tasks. We evaluated the baseline clinical characteristics and changes of cognitive outcome measures using SNSB-D in our cases from baseline to 3 months follow-up period, respectively. RESULTS: After a 3 month follow-up period, patients that underwent CAS showed significant improvement in cognitive function in total SNSB-D score compared to the baseline state of 18.1 points at 3 months (p<0.05). The other cognitive outcome measures showed significant improvements (p<0.05) in the task of confrontational naming, visual memory, and the scale of clinical dementia rating sum of box. CONCLUSION: We found that there might be a positive effect of carotid artery stenting on cognitive function from baseline to 3 months in patients with severe carotid artery stenosis.

PURPOSE: This study was performed to analyze human maxillary and mandibular trabecular bone using the data acquired from micro-computed tomography (micro-CT), and to characterize the site-specific microstructures of trabeculae. MATERIALS AND METHODS: Sixty-nine cylindrical bone specimens were prepared from the mandible and maxilla. They were divided into 5 groups by region: the anterior maxilla, posterior maxilla, anterior mandible, posterior mandible, and mandibular condyle. After the specimens were scanned using a micro-CT system, three-dimensional microstructural parameters such as the percent bone volume, bone specific surface, trabecular thickness, trabecular separation, trabecular number, structure model index, and degrees of anisotropy were analyzed. RESULTS: Among the regions other than the condylar area, the anterior mandibular region showed the highest trabecular thickness and the lowest value for the bone specific surface. On the other hand, the posterior maxilla region showed the lowest trabecular thickness and the highest value for the bone specific surface. The degree of anisotropy was lowest at the anterior mandible. The condyle showed thinner trabeculae with a more anisotropic arrangement than the other mandibular regions. CONCLUSION: There were microstructural differences between the regions of the maxilla and mandible. These results suggested that different mechanisms of external force might exist at each site.

PURPOSE: This study was performed to evaluate condylar surface changes and remodeling after orthognathic surgery using three-dimensional computed tomography (3D CT) imaging, including comparisons between the right and left sides and between the sexes. MATERIALS AND METHODS: Forty patients (20 males and 20 females) who underwent multi-detector CT examinations before and after surgery were selected. Three-dimensional images comprising thousands of points on the condylar surface were obtained before and after surgery. For the quantitative assessment of condylar surface changes, point-to-point (preoperative-to-postoperative) distances were calculated using D processing software. These point-to-point distances were converted to a color map. In order to evaluate the types of condylar remodeling, the condylar head was divided into six areas (anteromedial, anteromiddle, anterolateral, posteromedial, posteromiddle, and posterolateral areas) and each area was classified into three types of condylar remodeling (bone formation, no change, and bone resorption) based on the color map. Additionally, comparative analyses were performed between the right and left sides and according to sex. RESULTS: The mean of the average point-to-point distances on condylar surface was 0.11±0.03 mm. Bone resorption occurred more frequently than other types of condylar remodeling, especially in the lateral areas. However, bone formation in the anteromedial area was particularly prominent. No significant difference was found between the right and left condyles, but condylar surface changes in males were significantly larger than in females. CONCLUSION: This study revealed that condylar remodeling exhibited a tendency towards bone resorption, especially in the lateral areas. Condylar surface changes occurred, but were small.

Background: The purpose of this study was to establish effective measures and preventive managements to the cases of bloodborne exposures among the health care workers. Method: We reviewed 331 cases that were reported to the infection control services of five hospitals from March 2000 to February 2002. The SPSS PC 10.0 was used to analyze the date. Result: The proportion of registered nurses, doctors, housekeepers, unrse aid and technicians were 48.0%, 27.8%, 10.0%, 6.0%, and 5.4% in order. The proportion of female exposures was 75.2%. Fifty six point eight percent of exposure have been working less than 3 years. The data also indicated that there were differences by their Occupations. Thirty nine point six percent of the exposures occurred at the general ward, and 16.6% of them occurred at the operation room and 13.0% of them occurred at the intensive care unit. Most of the bloodborne exposures occurred during blood sampling (26.3%), putting away the needle including the recapping(18.4%). and giving injection (14.5%). The major instruments of exposures were syring-needle (79.6%), blade (7.3%), suture needle (6.1%), and direct contact with blood (2.7%). The hands were the most common body parts of exposures (95.2%). The bloodborne pathogens were hepatitis B virus (HBV, 38.1%(126/331), hepatitis C virus (10.3%), syphilis (4.5%), and human immuno-dificiency virus (2.7%). Forty one point three percent(52/127) of health care workers(HCWs) usually didn't realize whether they had antibody to the HBV or not at the time of exposure; Seventy five percent (39/52) of them found out later to be positive for HBV antibody. Only 48.7% (19/39) of them could get the medical treatment since they didn't know about immunity before the test. The cases with completion of management at the time of exposure, those of follow-up evaluations, and the cases with lost follow-up were 40.7%, 38.6% and 20.7%. in order. None of the cases were led to actual infections. Conclusion: The results from this study can be applied to establish effective measures of prevention and managements of the bloodborne exposures among the HCWs. If the laboratory data of HCWs were available at the time of exposure, more effective management would be possible. Also the results from this study emphasized the need for the systematic and practical follow-up.

Purpose: The purpose of this study is to determine the risk adjusted nosocomial infection (NI) rate and distribution of Nls and their causative pathogens in adult lCU. Methods: Prospective surveillance was performed at 12 lCU's of 5 acute care hospitals in Seoul and Kyonggi Do during a 3-months period from May to July 2002. The case finding was done by direct reviews of medical charts regularly for all patients by ICPs using CDC definitions. Results: Total NI rate was 10.18/1,000 patient-days in Medical-surgical ICU (MSICU) and 12.35/1,000 patient-days in Neurosurgucal ICU(NCI). Risk adjusted infection rate was 3.44 in indwelling catheter associated UTI 2.12 in central line associated BSI. 3.51/1,000 device-days in ventilator associated pneumonia in MSICU. There were 3.72, 2.26, 6.06/1,000 device-days in NCU. The infection rate by leu type showed no significant difference. The distribution of Nls were PNEU (28.99%). UTI (28.99%), BSI (18,84%), SSI(4.35%) in MSICU, and UTI(48.0%), PNEU(24.0%), BSI (14.0%), SSI(6.I) in NCU. The most commonly isolated organisms were Candida spp (38.6%), Enterococcus spp. (13.4%) in UTI, Staphylococcus aureus(36.2%), p. aeruginosa(18.8%) in PNEU and Coagulase negative staphylococcus(44.1%). S. aureus (14.7%) in BSL, S. aureus (19.8%) was the most common organism from overall nosocomial infections in the ICU, and 96.3% of S. aureus were MRSA. Conclusion: Distribution of site-specific nosocomial infection and isolated organisms were similar to the results of KOSNIC (Korea society for nosocomial infection control) surveillance in 1996. However, the total infection rate and a risk adjusted infection rate at MSJCU is lower than 1996's. This decrease is considered to be a result of efforts to prevention and control nosocomial infections.

This study compared total sodium amounts in 'Healthy Restaurant for Sodium Reduction' menu items located in Seoul, Chungcheong, and Gyeongsang in 2011 and 2012. In addition, this study explored reduced sodium cooking methods in 'Healthy Restaurant for Sodium Reduction'. This study monitored and collected menu samples from a total of 103 restaurants participating in 'Healthy Restaurant for Sodium Reduction' in 2011 and 2012. We also surveyed restaurant employees to identify reduced sodium cooking methods in 2012. The results showed significant reductions in total amounts of sodium in menu items of restaurants located in Seoul, Chungcheong, and Gyeongsang between 2011 (310.8+/-156.8 mg/100g) and 2012 (211.6+/-110.3 mg/100g). Amounts of sodium in all seven foodgroups showed significant reductions between 2011 and 2012: 'Gook/Tang' (from 226.6+/-127.7 mg/100g to 168.5+/-74.3 mg/100g), 'Jjigae/Jeongol' (from 385.8+/-111.7 mg/100g to 257.1+/-82.53 mg/100g), 'Noodle/Dumpling' (from 263.8+/-116.9 mg/100g to 194.1+/-55.6 mg/100g), 'Gui' (from 390.3+/-120.6 mg/100g to 258.8+/-92.7 mg/100g), 'Steamed dish' (from 305.3+/-124.3 mg/100g to 175.6+/-76.6 mg/100g), 'Bob' (from 273.7+/-162.5 mg/100g to 167.1+/-93.1 mg/100g), and 'Stir-fried dish' (from 368.6+/-116.6 mg/100g to 219.0+/-72.4 mg/100g). The survey results showed that responses for 'Reducing salt amount' were 75.7%, responses for 'Using enchovy stock, shrimp, radish, or fruit soup' were 64.1%, and responses for 'Liking the taste because it is bland' were 50%. This study indicates that 'Healthy Restaurant for Sodium Reduction' nutrition policy was successful for reducing sodium contents of restaurant menu items, and also consumers were satisfied with the tastes.
