Background
Studies regarding the discrimination of non-neoplastic lesion, adenoma, and cancer of the stomach using magnifying endoscopy with flexible spectral imaging color enhancement system (FIME) in each different channel of that system have not yet been reported.Aims
To ascertain the usefulness of FIME discriminating among the three kinds of gastric lesions.Methods
When finding a lesion to be a possible neoplasm using conventional endoscopy, the examiner discriminated among the three kinds of gastric lesions by observing the pit pattern on the lesion using magnifying endoscopy with white light (WLME) and then recorded the image. The procedure was repeated three more times with FIME with channel 0, 2, and 4. The four recorded images per lesion were then given to four raters for discriminating among the three kinds of gastric lesions.Results
The proportion of agreement and the degree of agreement between endoscopic and pathological diagnosis (AEP) by WLME were 0.85 and 0.76, respectively, and those by FIME were 0.91 and 0.86, respectively. All AEPs from discriminations with FIME was higher than that with WLME. AEPs from the discriminations with FIME with channel 4 were higher than those with FIME with channel 0 or 2. The degree of interobserver agreement among the results of the four raters was 0.42 for WLME and 0.50?C0.59 for FIME with each of the three different channels.Conclusions
FICE is useful in discriminating among non-neoplastic lesions, adenoma, and cancer of the stomach, and channel 4 of the FICE is better than channel 0 and 2 for the discriminations. 相似文献992.

Background
Siroliums-eluting stents (SES) and paclitaxel-eluting stents (PES) have been widely used for the treatment of coronary artery disease. We investigated 5-year clinical outcomes of patients treated with SES versus PES in a multicenter registry.Methods
We used a propensity score matching method with 2:1 matching, including 512 patients treated with SES and 256 patients treated with PES from March 2003 to December 2004. The primary endpoint was major adverse cardiac events, which included all-cause death, myocardial infarction (MI), and target vessel revascularization (TVR).Results
After matching, baseline characteristics were similar between the two groups. At 5 years, cumulative survival free of major adverse cardiac events, MI, and stent thrombosis did not differ between the two groups. Survival free of TVR at 5 years was higher in the SES group (88.4%) than the PES group (84.3%, Log-rank p = 0.016). In contrast to the trend toward more likely target lesion revascularization in the PES group during the first 2 years (hazard ratio 0.62, p = 0.057), target lesion revascularization tended to occur more frequently in the SES group from 2 to 5 years (hazard ratio 2.26, p = 0.099).Conclusions
Long-term risk of TVR was slightly lower with SES, compared with PES, despite no significant difference in major adverse cardiac events. However, the SES group had more frequent target lesion reintervention 2 to 5 years after stent implantation, whereas reintervention in the PES group occurred mainly within the first 2 years. This may reflect the temporal difference in neointimal growth of the two stent types. 相似文献994.

Background
The present study represents the first attempt at examining variation across Korean cohorts with respect to lifetime risk of DSM-IV psychiatric disorders.Aims
To present data on lifetime prevalence and projected lifetime risk, as well as age of onset (AOO) and demographic correlates of DSM-IV psychiatric disorders as assessed in the nationwide survey of a representative sample of Korean adults.Method
The survey was based on a multistage area probability sample of non-institutionalized Koreans aged 18–64?years. The Korean version of the Composite International Diagnostic Interview 2.1 (K-CIDI 2.1) was administered by lay interviewers.Results
Lifetime prevalence of any disorder was 24.6%. Alcohol abuse (9.2%), alcohol dependence (7.0%), major depressive disorder (5.6%), specific phobia (3.8%), and GAD (1.6%) were the most common disorders. The median AOO was earliest for anxiety disorders (age 29), latest for mood disorders (age 47), and intermediate for alcohol use disorders (age 31). Compared to observed lifetime prevalence (24.6%), 35.0% of Koreans will eventually experience one of these disorders. Further, half of the population who present with a psychiatric disorder do so by the age of 32 and younger cohorts are at greater risk for most disorders.Conclusions
About one-third of the Korean adult population will meet the criteria for a DSM-IV psychiatric disorder at some time during their life. The median age of onset varies from disorder to disorder and younger cohorts appear to be at greater risk for most disorders. 相似文献998.

Purpose
The diagnosis of insomnia is based on the presence of four different symptoms: difficulty in initiating sleep (DIS), difficulty in maintaining sleep (DMS), early morning awakening (EMA), and non-restorative sleep (NRS). This study investigated the differences in sociodemographic correlates and psychiatric comorbidity between the four symptoms of insomnia in the general population of South Korea.Methods
A sample of the population aged 18–64 (N?=?6,510) was questioned using a face-to-face interview. Insomnia was defined as having at least one of the four following symptoms three or more times per week: DIS, DMS, EMA, and NRS. Psychiatric disorders were evaluated using the Korean version of Composite International Diagnostic Interview. Logistic regression analysis was used to test each of the sleep outcomes (DIS, DMS, EMA, or NRS) for an association with sociodemographic and clinical variables.Results
The prevalence of DIS, DMS, EMA, and NRS were 7.9?% (95?% CI 6.6–9.5?%), 7.9?% (95?% CI 6.5–9.6?%), 4.9?% (95?% CI 3.9–6.0?%), and 14.8?% (95?% CI 12.6–17.4?%), respectively. The overall prevalence of insomnia was 19.0?% (95?% CI 16.1–22.2?%). Being separated, divorced, or widowed, being single, having a part-time job, having a psychiatric illness, and having a physical illness were all significantly related to insomnia. Older age also increased the risk of DMS and EMA, and younger age was a risk factor for NRS. The presence of most psychiatric disorders was significantly related to insomnia. However, the relationship between the psychiatric illness and each insomnia symptom varied and was dependent on the insomnia symptom.Conclusions
Most psychiatric disorders were significantly associated with each insomnia symptom in different ways. Differences in sociodemographic and clinical correlates between the four insomnia symptoms implied the heterogeneous characteristics of insomnia as defined by the current diagnostic criteria. 相似文献999.
