STATEMENT OF PROBLEM: Every effort has been continually made to obtain objectivity in measuring the longevity of fixed restorations, such as by establishing unified judgement standard for deciding success and adopting statistical method that analyzes the data of successful and failed cases at the same time. In Korea, however, desired level of development has not to be made in this field yet. PURPOSE: This study, adopting California Dental Association (CDA) quality evaluation system, established objective standard for deciding success, and inferred the longevity of fixed restorations and their failure analysis through adopting Kaplan-Meier survival analysis. Material and method. In order to assess the longevity of fixed restorations serviced in Korea and causes of failure, a total of 1109 individuals (aged 15-74, 716 women and 393 men loaded with 2551 unit fixed restorations, and 1934 abutments) who lived in Kyung-In Province were examined and the findings were as follows: RESULTS: 1. Length of service of fixed restorations serviced in Korea was 6.86+/-0.15 yr (mean), 5.5 yr (median), and the rate of success was 65.82% in 5 year survival, and 21.15% in 10 year survival. 2. When there was patient's need for replacing old prosthetics, longevity of fixed restorations was 7.51+/-0.27 yr (mean), 7 yr (median), and the rate of success was 61.08% in 5 year survival, and 17.57% in 10 year survival. 3. Longevity of fixed restorations was longest in the over-sixty age group(9.21+/- 0.66) and that of the teen age group(3.39+/-0.28) was shortest (p<0.05). 4. Longevity of fixed restorations of women (7.38+/-0.18 years) was longer than that of men (6.00+/-0.26)(p<0.05). 5. As for the provider factor (such as unlicensed performers, university hospitals, and private clinic), there was no statistically significant difference in longevity of fixed restorations. 6. Defective margin (34.78%), periodontal disease (12.15%), periapical involvement (11.73%), was the most frequent causes of failure and poor esthetics group showed the longest life above all (p<0.05). Actual frequent causes of failure after removing old prosthetics were defective margin, periapical involvement, periodontal disease and uncemented restoration. In 75.67% of the cases, abutment state after removing old prosthetics was good enough for loading another prosthetics. 7. There was found to have statistically significant influence between longevity of single crown (6.35+/-0.20 yr) and that of 3 unit fixed restorations (7.60+/-0.30 yr) (p<0.05). In each case the most frequent cause of failure was defective margin. 8. The number of cantilever pontic, pontic/abutment ratio, oral hygiene status were found to have no statistically significant influence on longevity of fixed restorations in all groups (p>0.05). 9. Longevity of fixed restorations made of non precious metal was longest (9.60+/-0.40 yr), semi precious and precious trailing behind(p<0.05). 10. Group function group (37.04%) and partial group function group (44.62%) were predominant in frequency but showed no correlation between them and among different types of occlusal plane and different types of occlusal surface (p>0.05). 11. Longevity of fixed restorations was longest in the centric interference group(9.35+/-0.62) (p<0.05) among different types of occlusal interference. CONCLUSION: We found that longevity of fixed restorations serviced in Korea is affected by age, gender and type of material, and that most frequent cause of failure is defective margin. In order to assess the accurate longevity of fixed restorations, unified research design, overcoming inter-observer difference and establishing the objective research items are needed. Furthermore, it is thought that prospective approach through thorough study and regular follow-ups is needed just from the start of research. Nationwide detailed studies on length of service of fixed restorations manufactured in Korea are hoped to be conducted hereafter.

BACKGROUND: The laparoscopy requires CO2 insufflation and posture changes for operational convenience. However, above circumstances affect the cardiopulmonary systems significantly. And then intracranial pressure (ICP) may be also influenced. METHODS: To ascertain the changes of ICP, an experimental study was performed, in which the parameters of hemodynamic status, arterial blood gas components and ICP were measured from twelve cases of Korean mongrel dogs. Pneumoperitoneum was produced by CO2 insufflation(15 mmHg) and then posture was altered from horizontal to head-down tilt of 20, 30 and 40 degree*. The measurements were obtained before (control), after CO2 insufflated horizontal position at 20, 40 and 60 minute in CO2 insufflated tilt** and CO2 deflated horizontal***. RESULTS: MAP and HR were not related to the insufflated time and degree of tilt. CVP and PCWP were significantly increased after CO2 insufflated tilt (p<0.01), but returned to control after deflated supine. PaCO2 was not significantly changed after CO2 insufflated supine, but grdually increased with degree of tilt and time (p<0.01). ICP was increased at 40 and 60 minute of 20degree, and at 20 minute of 30degree(p<0.05), then markedly increased at 40 and 60 minute of 30degree, and at 20, 40 and 60 minute of 40degreetilt (p<0.01). The increment of ICP was parallel with time and degree of tilt. But, ICP was returned to control after deflated supine. CONCLUSIONS: ICP was increased significantly during laparoscopy in head-down tilt, although it was reversible. Therefore, the patient must be given special attention during laparoscopy in whom the increment of ICP may be harmful.

A field trial on the control effect of fipronil poison bait against German cockroaches (Blatella germanica) was carried out at different restaurant types in Sinchon, Seoul, Republic of Korea. Monitoring was performed applying food baited traps for 2 days per week. Reduction rates of German cockroaches by applying fipronil baits were 90.9% at Korean restaurants, 96.4% at Chinese restaurants, and 89.4% in beer hall kitchens after 4 weeks of the treatment. Overall average of the reduction rate was 93.9%. As the natural reduction rate at untreated restaurants was 11.5% after 4 weeks, a correction of the average reduction rate by applying the Abbot formula was 93.1%.

Simultaneous bilateral proximal femoral fractures are extremely rare, and a few have been reported in and outside the country. It may have various causes, and most cases were associated with major trauma, repetitive minor trauma, seizure, parathyroid or renal dysfunction, and anti-epileptic medications. We experienced a case of simultaneous bilateral proximal femoral fractures after generalized tonic-clonic seizure in a 70-year-old female. Herein, we report it with a review of the literature.

Axin is a negative regulator of the Wnt/beta-catenin pathway and is involved in the regulation of axis formation and proliferation. Involvement of Axin in the regulation of other signaling pathways is poorly understood. In this study, we investigated the involvement of Akt in growth regulation by Axin in L929 fibroblasts stimulated by EGF. Akt activity was increased by EGF treatment and Ras activation, respectively. Both the EGF- and Ras-induced Akt activations were abolished by Axin induction, as revealed by both Western blot and immunocytochemical analyses. The proliferation and Akt activation induced by EGF were decreased by Axin induction, and the effects of EGF were abolished by treatment of an Akt-specific inhibitor. Therefore, Axin inhibits EGF-induced proliferation of L929 fibroblasts by blocking Akt activation.

The Wallenberg's syndrome is produced by infarction of lateral medulla. Isolated ipsilateral axial lateropulsion without other common symptoms of Wallenberg syndrome has rarely been reported as manifestation of lateral medullary infarction. The responsible anatomical structure of ipsilateral axial lateropulsion is still uncertain. We describe a patient with lateral medullary infarction who present with isolated ipsilateral axial lateropulsion without other symptoms of Wallenberg syndrome.

PURPOSE: Adverse reactions to mosquito bites have been recognized for some time, and these usually consist of large swellings, generalized urticaria, angioedema, and less frequently asthma. There have been some efforts to define immunologic characteristics of mosquito allergens throughout the world. But, in Korea, the immunologic analysis of mosquito allergen have not been made. METHODS: Extracts of locally distributed female mosquito Culex pipiens, were prepared from their heads and thoraxes. By sodium dodecylsulfate-polyacrylamide gel electrophoresis, proteins of two extracts were isolated. Then their proein bands were transferred to nitrocellulose membrane. Immunoblotting was performed with sera of allergic patients to mosquito bites, then completed by antibodies to human IgE. RESULTS: Immunoblotting showed IgE binding proteins weighing 70 kD, 60 kD, 34 kD in Culex pipiens. CONCLUSION: We found that mosquito antigens induced IgE response, and it suggested that species-specific antigens exist. Further investigation using salivary gland extracts from Culex genus are needed in identifying specific allergens.

PURPOSE: Dense breasts have been suggested as a risk factor for breast cancer, but controversy still remains. This study evaluates the association of reproductive and hormonal factors with dense breasts among Korean women. MATERIALS AND METHODS: Using a cross-sectional design, 516 women were recruited and classified for breast density patterns as being either fatty or dense, using the Breast Imaging Reporting and Data System (BI-RADS) of the American College of Radiology. Univariate and multivariate logistic regression models were used for statistical analysis. RESULTS: In univariate logistic regression, older age, higher body mass index, older age at menarche, and oral contraceptive use were associated with more fatty breasts. On the contrary, longer duration of education, alcohol consumption, lower parity, menopause and use of hormone replacement therapy were associated with dense breasts. After adjustment, age and body mass index were inversely associated with breast density (p-value for trend <0.01, respectively), whereas nulliparous and premenopausal status were positively associated. Compared to women who had > or =2 children, nulliparous women had an 11.8-fold increase of dense breasts (p-value for trend <0.01). Compared to postmenopausal women, premenopausal women had 2.4-fold increase of dense breasts (odds ratio, 2.42; 95% confidence interval, 1.36 to 4.32). CONCLUSION: Young age, lower body mass index, lower parity, and premenopausal status were significantly associated with dense breasts in Korea.

PURPOSE: The purpose of this study was to investigate current statistics relating to foreigners who visit a Korean emergency department (ED). METHODS: Subjects included in this study were 125,263 patients who visited one Korean ED from January 1, 2008 to December 31, 2010. We divided subjects into two groups, natives (Koreans) and foreigners (non-Koreans). We compared the two groups according to their age, sex, chief medical complaints, department to which they were referred, their final diagnosis, results of treatment applied, ED residence time, mortality rate, total billed cost of treatment, balance of any unpaid bills and method of visiting the ED. RESULTS: Of the total patients included in the study, 119,864 (95.7%) were natives and 5,399 (4.3%) were foreigners. In natives, the majority were 0 to 10 years old (35.1%), while foreigners were mostly 41 to 50 (22.8%) years old. The most common symptom in both natives and foreigners was fever. The most common diagnosis for foreigners was head, face, and neck injury (13.8%). The main referred departments for foreigners were internal medicine (20.1%), pediatric medicine (16.9%), and orthopedics (14.3%). The admission rate for foreigners (13.0%), was lower than that of natives (17.3%). The mortality rate for foreigners (0.5%) was higher than that of natives (0.3%). The ED residence time for foreigners was higher than that of natives. The total billed cost of treatment and balance of unpaid money by foreigners was higher than that of natives. For foreigners, the proportion of medical fees paid from personal accounts and industrial medical insurance were higher than those of natives. CONCLUSION: Medical insurance and policy for the management of foreigners who visit the ED must be improved.
