  • Objective : This study was designed to analyze seizure outcome and to investigate the prognostic factors for predicting seizure outcome according to the preoperative evaluations, surgical procedures, topectomy sites and histopathological findings in patients with extratemporal lobe epilepsy [ETLE]. Methods : This study comprised 63 patients with ETLE who underwent surgery. Preoperative evaluations included semiologic analysis, chronic video-EEG monitoring, and neuroimaging studies. Surgical procedures consisted of topectomy in 51 patients, corpus callosotomy in 9, functional hemispherectomy in 2, and vagus nerve stimulation [VNS] in 1. Histopathological findings were reviewed. Postoperative seizure outcomes were assessed by Engel's classification at the average follow up period of 66.8 months. Chi-square test was used for statistics. Results : Total postoperative seizure outcomes were class I in 51 [80%] patients, class II in 6 [10%], class III in 6 [10%]. Patients with structural abnormalities on neuroimaging study showed class I in 49 [88%] patients [p<0.05]. Patients with focal and regional ictal EEG onset revealed class I in 47 [90%] patients [p<0.05]. Semiologic findings, surgical procedures, topectomy sites and histopathological findings did not show statistical correlation with seizure outcome [p<0.05]. Conclusion : A good seizure outcome was obtained in patients with ETLE. The factors for favorable seizure outcome are related to the presence of structural abnormalities on neuroimaging study, and focal and regional ictal EEG onset.

  • Background: Panax ginseng is a well-known immune modulator, and there is concern that its immune-enhancing effects may negatively affect patients with rheumatoid arthritis (RA) by worsening symptoms or increasing the risk of adverse effects from other drugs. In this randomized, crossover clinical trial, we evaluated the impact of Korean Red Ginseng (KRG) on disease activity and safety in RA patients. Methods: A total of 80 female RA patients were randomly assigned to either the KRG (2 g/d, n = 40) treatment or placebo (n = 40) groups for 8 wk, followed by crossover to the other treatment group for an additional 8 wk. The primary outcome was the disease flare rate, defined as worsening disease activity according to the disease activity score 28 joints-erythrocyte sedimentation rate (DAS28-ESR). The secondary outcomes were development of adverse events (AEs) and patient reported outcomes. Outcomes were evaluated at baseline and 8 wk and 16 wk. The outcomes were compared using the Chi-square test. Results: Of the 80 patients, 70 completed the full study. Their mean age was 51.9 yr, and most exhibited low disease activity (mean DAS28-ESR $3.5{\pm}1.0$) at enrollment. After intervention, the flare rate was 3.7% in each group. During KRG treatment, 10 AEs were reported, while five AEs were developed with placebo; however, this difference was not statistically significant (p = 0.16). Gastrointestinal- and nervous system-related symptoms were frequent in the KRG group. Conclusion: KRG is not significantly associated with either disease flare rate or the rate of AE development in RA patients.

  • Purpose: The purpose of this study was to examine anger-expression patterns and their association with state and trait anger and physical and psychological health status in health care workers. Method: Four hundred and forty eight nurses, physicians and technicians from a large medical center completed standardized questionnaires of anger, anger-expression patterns and mood. They also had blood pressure, cholesterol, blood glucose and body mass index measured during their annual physical examinations. Data was analyzed using descriptive statistics, independent t-test, chi-square and ANOVA. Results: Subjects showed two major clusters of anger-expression patterns: anger-control and anger-in/out. Subjects with the anger-in/out pattern reported higher state and trait anger and more anxiety, depression and fatigue than subjects with the anger-control pattern. Physical health indicators, however, were not significantly different between the two clusters of anger-expression patterns. Conclusion: Anger-expression patterns are associated with psychological health status but not with physical health status. Anger-expression patterns, however, need to be examined over time to assess their long-term effects on the physical and psychological health status in future studies.

  • Purpose: The association between pain and sleep is described as a vicious cycle and psychological distress is well known as comorbid condition in the patients with pain and sleep problems. The aim of the study was to evaluate the prevalence of self-reported sleep disturbance and its relationship to clinical and psychological profiles in temporomandibular disorder (TMD) patients. Methods: The sample consisted of 123 TMD patients (90 women and 33 men), with a mean age of $39.9{\pm}15.4years$. Self-report measures of sleep quality, pain and psychological profile were conducted via the Pittsburgh Sleep Quality Index (PSQI), the Brief Pain Inventory and the Symptom Checklist-90-Revision at the initial visit. The primary diagnosis of TMD were categorized as TMD with internal derangement without pain, TMD with joint pain, TMD with muscle pain and TMD with joint-muscle combined pain. The chi-square test, independent t-test, oneway ANOVA and multiple linear regression analysis were used for statistics. Results: The patients was grouped as good sleepers (n=32, scores of 5 and lower) and poor sleepers (n=91, scores of 6 and higher) according to the recommended cutoff point of the global PSQI score (>5). TMD patients with pain showed poor sleep quality than TMD patients with internal derangement without pain. Poor sleepers had high pain interference and elevated psychological distress. Among them, pain interference and depression were significant predictors to sleep quality. Conclusions: The results suggest that sleep disturbance is a prevalent complaint in TMD patients, and sleep problems in TMD patients are associated with pain and psychological distress.

  • Background: Ovarian cancer is recognized as the fourth leading cancer in Malaysia. However, women do not always seek help in a timely manner and gaps in awareness may influence screening uptake and presentation. The purpose of this study was to determine levels of awareness of ovarian cancer risk factors in female population in Penang, Malaysia. Materials and Methods: A cross-sectional study was conducted in Penang, Malaysia from January until February 2014. Eighty-seven women were selected by convenient sampling. Awareness of risk factors of ovarian cancer was assessed using a self-administered questionnaire. Data were analyzed using statistical package for the social sciences (SPSS) version 20.0 for descriptive statistics and Pearson chi-square test for the association between socio-demographic data and awareness. A p value ${\leq}0.05$ was considered statistically significant. Results: In all, 74.7% of participants answered correctly for the risk factor of increasing age, although 94.3% were unaware of increased risk of tall women. A majority, 71.3%, had a low level of awareness of ovarian cancer risk factors. There was a significant association between age and knowledge (p=0.047). Additionally, there was a significant association between higher education level and level of awareness of ovarian cancer risk factors (p=0.039). Conclusions: This study revealed that awareness of ovarian cancer risk factors among Malaysian women is low. The results show a need for improved public understanding about ovarian cancer risks and provision of important information for health professionals about initiatives needed for future awareness, prevention and screening programs.

  • Background: The survival of patients with hypopharyngeal cancer is low amongst head and neck cancer cases. The incidence rates of hypopharyngeal cancers in our population are amongst the highest in the world and there are limited data available on the literature on varied responses to first course of treatment with radiotherapy (RT) and concurrent chemo-radiotherapy (CRT) in our population. Materials and Methods: Clinical characteristics and initial responses to treatment in patients who had received radiotherapy and chemo-radiotherapy in a regional cancer center from January 2010 to December 2013 were evaluated. The data were obtained from the hospital cancer registry, and analysis was carried using descriptive statistics. Pearson's chi-square was used to test for differences in the variables and p<0.05 was considered statistically significant. Results: A total of 554 patients were included in the analysis, 411 (74.2%) receiving RT and 143 (25.8%) being given CRT. There was significantly lower number of patients above 70 years with a higher proportion of patients below 50 years who had received CRT (p<0.05). Some 79.3% and 84.6% of patients in the RT and CRT groups respectively presented with a favorable performance status, and in the RT group 240 (58.4%) showed complete response (CR), and in the CRT group 103 (72.0%) showed CR at the first follow-up (p<0.05). Conclusions: Concurrent chemo-radiotherapy gives better short term response to treatment in locally advanced hypopharyngeal cancers.

  • The heightened consumers' interest in health and well-being gave rise to the needs for performance infants' wear, which are made with environmentally-friendly and healthy functional materials. This study intends to compare purchasers and non-purchasers of performance infants' wear in terms of their shopping behavior, shopper and infants' characteristics, and reasons for purchasing or not purchasing performance infants' wear. A total of 241 questionnaires were collected from women with infants less than 4 years old, who are living in the Seoul metropolitan area. Using SPSS 10.0, chi-square, paired t-test, and descriptive statistics were calculated to analyze the data. The results of the study were as follows: First, the purchasers of performance infants' wear shopped more often at department stores and were more likely to buy comparatively high-price products than non-purchasers. Second, for performance infants' wear, non-purchasers considered laundry/care methods and fiber contents more, while purchasers considered colors, design, price, and performance of the products less than for infants' wear in general. Third, in terms of demographic characteristics, significant differences were found for the number of children and the child's birth order. Fourth, the primary reason for buying performance infants' wear was 'health'. The primary reason for not buying was 'too high price' and 'lack of information'. The 'high price compared to its performance' and 'lack of color choice' were among the purchasers complaints about performance infants' wear.

  • Purpose: This study aimed to identify the alcohol drinking pattern of parents and to analyze drinking related factors in problem drinking among adolescent's parents. Method: This study was conducted through a structured questioning from November 5th to 22th in 2002. Those are 2,522 parents of the students of the 1st and 2nd grade who were selected randomly among 26 middle and high schools located in Socho-gu, Seoul. Data was analyzed using SAS program that included descriptive statistics, Chi-square test, and multiple logistic regression analysis. Result: 1. For frequency of drinking, 33.1% of the subjects responded to drink two-four times a month, 26.0% drink more than two times a week. 2. For the amount of drinking, 29.6% drink one or two glasses while 9.4% drink over ten glasses at a time. 3. The mean AUDIT score was 8.27 7.02(score of range: 0- 40). 4. Based on AUDIT score, drinkers with less than eight point from AUDIT(normal group) were 55.1%, from more than eight point to less than twelve point from AUDIT(problematic drinker) were 16.3%, and more than twelve point from AUDIT(alcohol abuse and dependency) were 28.6%. 5. Based on more than twelve point from AUDIT, female(mother), high school and, have religion, housekeeper were the significantly higher score than counter parts. Conclusion: Alcohol drinking pattern and level of drinking of their parents links to their children's drinking and results in family, social, and national loss. Active prevention is needed. Specially, pertinent education about drinking and public education for mothers who are housekeepers should be carried out with concentrated intervention programs for the problematic drinker so alcohol abuse and dependency can be reduced.

  • Purpose: The purpose of the study was to identify differences in physiological· psychological environmental behavioral characteristics between obese and control children participating in a health camp and to identify the factors related to childhood obesity. Methods: Two hundred eighty seven children aged 6 to 12 years were recruited from a health camp for elementary students in D city, Korea. Data collection was done on November 28 and 29, 2009. Anthropometric measurements, blood tests, and self-report surveys were conducted. Chi-square test, independent t-test, ANCOVA, and multiple logistic regression were performed using PASW statistics 18.0. Results: Obese children had adverse conditions for both physiological and psychological characteristics. In terms of environmental and behavioral characteristics, high maternal BMI and more than two hours of TV watching were significantly associated with high risk of childhood obesity (OR=1.11, 95% CI=1.02-1.21; OR=2.05, 95% CI=1.23-3.41). Conclusion: Through a multi-factorial approach, the current study identified the differences between obese and control children participating in a health camp and risk factors of childhood obesity. These findings provide preliminary data and perspectives on intervention research for prevention and management of childhood obesity.
