PURPOSE: We carried out this study to determine if there is any difference in the occurrence rate of the epileptiform discharge between awake EEG and sleep EEG and if there are any factors influencing on the occurrence rate of EEG. METHODS: This study included 178 epileptic children who had visited neurology clinic of the department of pediatrics, Pusan National University Hospital from July 2005 to July 2006. The medical and EEG records of these children who had had both awake EEG and sleep EEG were reviewed. We analysed the occurrence rate of the epileptiform discharge between awake EEG and sleep EEG. We investigated the related clinical factors which included sex, seizure types, underlying causes, age at first seizure, antiepileptic drug (AED) medication, age at recording, and background activity. RESULTS: Among 178 epileptic children, 91 patients (51.1%) showed epileptiform discharge in awake or sleep states, 10 patients (11.0%) abnormal only in awake, 40 patients (44.0%) abnormal only in sleep, 41 patients (45.0%) abnormal in both awake EEG and sleep EEG. The occurrence rate of sleep EEG was 81 of 178 patients (45.5%) which was more than that of the awake EEG (28.7%) (P<0.001). The occurrence rate of sleep EEG is more than that of the awake EEG regardless of sex and underlying causes. But there is no significant difference from awake EEG and sleep EEG in finding the epileptiform discharge in the patient with generalized seizure, younger than 5 years old at first seizure, younger than 10 years old at recording, no antiepileptic medication, and abnormal background activity. CONCLUSION: The sleep EEG is thought to be more helpful in the diagnosis of childhood epilepsy.

Purpose: The purpose of this study was to assess the diet intake status and quality of adults from North Korea who had lived in Seoul and Gyeonggi-do, using the nutrition quotient (NQ) for Korean adults. Methods: A number of 166 adults aged from 20 to 64 years were enrolled as study subjects.A structured questionnaire was used to collect information on their demographic characteristics, food consumption frequency, eating behaviors, and NQ. The NQ score was then used to measure the overall diet quality. The NQ score was composed of four major agebased categories. ‘Balance’, ‘Diversity’, ‘Moderation’, and ‘Dietary behavior’ were utilized as scores for measurements within each of the four categories. The scores for all four categories were summed up, resulting in the total NQ score. Participants’ age groups were stratified by 20’s, 30’s, 40’, and over 50’s. A χ2 test and generalized linear regression (GLM) model were used to assess a significance for difference of subject distribution in categorical and continuous variables in the food consumption frequency, eating behaviors, and NQ scores. Results: Participants in younger age groups were more likely to report consumption of ramyeon, fast food, sweet and greasy baked products, processed beverage, delivery food, and night snacks than the older age groups. Most importantly, participants in 20’s age group were less likely to report the total NQ and moderation score than the 50’s age group. Conclusion In this study, the 20’s age group displayed a lower NQ characteristic for an unbalanced diet. Therefore, it is imperative for adults from North Korea to be given individualized diet instructions along with nutritional education programs.

Background/Aims: We investigated sex- and stage-specific associations of body mass index (BMI), fasting glucose, and high-density lipoprotein cholesterol (HDL-C) with gastric cancer. Methods: In total, 3,382 patients with gastric cancer and 19,609 healthy controls were enrolled. BMI was categorized into five groups. HDL-C was classified as low (< 40 and < 50 mg/ dl in males and females, respectively) and normal (≥ 40 and ≥ 50 mg/dl in males and females, respectively). Logistic regression analysis was performed to calculate odd ratios (ORs) and 95% confidence intervals (CIs). Results: After adjustment, low BMI (OR, 1.44; 95% CI, 1.13–1.84), low HDL levels (OR, 2.28;95% CI, 2.07–2.50), and high fasting glucose levels (OR, 2.94; 95% CI, 2.22–2.99) were associated with gastric cancer, whereas high BMI (OR, 0.61–0.81) was inversely associated with gastric cancer. In sex-specific analysis, BMI was inversely associated with gastric cancer only in males (trend: p < 0.001). Low serum HDL and high fasting glucose levels were strongly associated with gastric cancer in both males and females. The effect of high glucose content was more pronounced in females (OR, 4.02) than in males (OR, 2.58). BMI was inversely associated with both AGC (trend: p < 0.001) and EGC (trend: p = 0.001). Low serum HDL and high fasting glucose levels were strongly associated with gastric cancer in EGC and AGC. Conclusions The effect of BMI on gastric cancer varies by sex and stage, whereas low HDL levels are associated with gastric cancer regardless of these factors.

BACKGROUND: Bacterial contamination of platelets represents the highest infectious risk for a transfusion. In this study, we evaluated 2 culture-based systems that have been approved by the US FDA for bacterial screening. METHODS: Platelet concentrates were inoculated with 5 bacterial species to give a final concentration of 10(0), 10(1) and 10(2) CFU/mL. Samples for culture were taken immediately after inoculation (0 hr sample) and after 24 hrs (24 hr sample). For the BacT/ALERT 3D system, a 10 mL sample was inoculated into an aerobic culture bottle and incubated for 7 days. For the Pall eBDS system, 3 mL samples were taken from the 0 hr and 24 hr samples, respectively. The samples were incubated for 24 hrs and 30 hrs. RESULTS: Both systems detected all inoculated units both in the 0 hr and 24 hr samples, except for units inoculated with K. pneumoniae. Eleven units out of 30 units inoculated with K. pneumoniae were detected by the BacT/ALERT 3D system in the 24 hr samples. The Pall eBDS system detected 8 of 30 units in the 24 hr samples. CONCLUSION: Implementation of either system will decrease the risk of transfusing bacterially contaminated platelets. However, testing for bacterial contamination will not completely prevent septic transfusion reactions; pathogen inactivation that is now available should also be considered as an alternative method to reduce the risk of bacterial contamination.

OBJECTIVE: Chronic subdural hematoma (CSDH), a disease commonly encountered by neurosurgeons, is treated by burr hole drainage (BHD). However, the optimal surgical technique among the three types of BHD has not been determined. METHODS: We conducted a retrospective study on BHD performed on 93 patients who were diagnosed with CSDH. The subjects were divided into three groups based on the surgical technique performed: single BHD without irrigation (Group A, n=31), double BHD without irrigation (Group B, n=32), and double BHD with irrigation (Group C, n=30). The clinical factors, radiological factors and recurrences were compared between the three groups. Moreover, independent factors affecting the recurrence were analyzed. RESULTS: The change in hematoma thickness was 29.77+/-7.94%, 49.73+/-12.87%, and 75.29+/-4.32% for Group A, B, and C, respectively, while the change in midline shift was 40.81+/-15.47%, 51.78+/-10.94%, and 56.16+/-16.16%, respectively. Thus, Group C showed the most effective for resolution of hematoma and midline shift (p<0.05). Group A, B, and C had 12 cases (38.7%), 8 cases (25.0%), and 3 cases (10.0%) of recurrences, respectively. Group C had a statistically significantly fewer recurrence rate than Group A (p<0.05). Double burr hole, irrigation, and coagulopathy were each identified as independent factors that reduce recurrence (p<0.05). CONCLUSION: Among the three techniques, the double BHD with saline irrigation resulted in the fewest recurrences. It is probably the most effective technique for preventing the recurrence of CSDH.

BACKGROUND: With the rapid aging of the Korean population and the steady decrease in the donor population during the past few years, there is a need for measures to ensure balance between blood demand and supply. The trends of the donor population and donor deferral during the past eleven years (1995~2005) were examined to obtain basic data to be used in donor management policy-making. METHODS: Data on the donor population, presenting donors, deferred donors and the reasons for deferral were examined by searching the Blood Information Management System (BIMS) and Annual reports of the Korean Red Cross. RESULTS: The number of presenting donors increased until 2003. However, the actual number of eligible donors has been decreasing since 1999 due to the increase in donor deferral. By enforcing donor eligibility criteria, the donor deferral rate in 1998 increased by 75.2% compared with the previous year, and the deferral rate was 21% in 2005. A low blood specific gravity (SG) was the most common reason for deferral, and more than 90% of those deferred due to a low SG were women. CONCLUSION: In order to assure an adequate donor base, policies should not only target donor recruitment but also the management of deferred donors. The adequacy of currently applied donor eligibility criteria should be reevaluated, and deferred donors should be counseled about their reason for deferral in order to encourage donation. Furthermore, the hemoglobin criteria for women should be reconsidered.
