OBJECTIVES: The prevalence of psychiatric disorders in homeless people is higher than the prevalence in a general population. With the increasing interests in homeless people after the economic crisis in Korea, psychiatrists started to investigate the prevalence of psychiatric disorders in homeless people. This study is to assess the prevalence of psychiatric disorders in homeless men living in a city shelter in Seoul and to compare these results with those of previous epiaemiological studies in Korea of homeless people and abroad. METHODS: Among 960 homeless men living in a city shelter in Seoul, 420 men were selected randomly from December 14 to December 29, 1999. Eight trained interviewer administered the Korean version of Composite International Diagnostic Interview (K-CIDI) to the subjects. The lifetime, one-year, and one-month prevalence of the psychiatric disorders in this study were compared to those of the previous studies of Korean general population and of homeless people abroad. RESULTS: The lifetime, one-year, and one-month prevalence of total psychiatric disorders were 71.7%, 49.8% and 45.0% respectively. The lifetime prevalence of nicotine dependence/withdrawal, alcohol use disorders (abuse/dependence), substance use disorders, major depressive disorder, psychotic disorders, and anxiety disorders were 31.0%, 58.6% (39.3%/19.3%), 3.1%, 11.7%, 2.4%, and 16.9% respectively. CONCLUSION: This study suggested that the prevalence of psychiatric disorders in homeless men is higher than the prevalence in general population, as the previous studies in Korea. The prevalence of alcohol use disorder was highest. The prevalence of non-alcohol substance use disorder and psychotic disorder were lower than the prevalence of these disorders in homeless people of other countries. These results suggest that there is a need to treat the psychiatric disorders, especially alcohol use disorder which is the major psychiatric problem in homeless men.

PURPOSE: To demonstrate the MRI findings of olivopontocerebellar atrophy. MATERIALS AND METHODS: We retrospectively reviewed the MRI findings of eight patients who had been diagnosed by clinical manifestation and the peculiar pattern of atrophy and signal change on MRI. RESULTS: Seven patients had an atrophy of the olive, pons and cerebellum and increased signal change of the transverse pontine fiber, median raphe and middle cerebellar peduncle on T2WI. Of these, six patients had severe atrophy of the olive, pons and cerebellum and decreased signal change of the basal ganglia, red nucleus, substantia nigra or dentate nucleus on T2WI. Additionally, four of six patients had a cerebral atrophy. Except one patient who had an urinary incontinence, these 5 patients had not been associated with extrapyramidal or autonomic symptom. The other patient with relatively short duration of the disease had only cerebellar atrophy without signal change on T2WI . CONCLUSION: With progressing of the olivopontocerebellar atrophy, cerebral atrophy and decreased signal change of the basal ganglia, red nucleus, substantia nigra or dentate nucleus on T2WI is combined. Thus, MRI is essential in establishing the diagnosis and evaluating the severity of olivopontocerebellar atrophy.

BACKGROUND: Though infections of Helicobacter pylori (H. pylori) are closely associated with activation of host angiogenesis, the underlying mechanisms, as well as the strategy for its prevention, have not been identified. Here, we investigated a causal role of H. pylori infection in angiogenesis of gastric mucosa and a potent inhibitory effect of a gastric proton pump inhibitor (PPI) on the gastropathy. MATERIALS AND METHODS: A comparative analysis of CD 34 expression in tissues obtained from 20 H. pylori-associated gastritis and 18 H. pylori-negative gastritis patients was performed. Expression of HIF-1alpha and VEGF were tested by using RT-PCR. To evaluate the direct effect of H. pylori infection on differentiation of endothelial HUVEC cells, we carried out an in vitro angiogenesis assay. RESULTS: H. pylori-associated gastritis tissues showed significantly higher density of CD34+ blood vessels than did H. pylori-negative gastritis tissues, and the levels were well correlated with expressions of HIF-1alpha. Conditioned media from H. pylori-infected gastric mucosal cells stimulated a tubular formation of HUVEC cells. We also found a significant inhibitory effect of PPI, an agent frequently used for H. pylori eradication, on H. pylori-induced angiogenesis. This drug effectively inhibited the phosphorylation of MAP kinase ERK1/2, which is a principal signal for H. pylori-induced angiogenesis. CONCLUSION: The fact that PPIs can down-regulate H. pylori-induced angiogenesis suggest that anti-angiogenic treatment using PPI may be a preventive approach for H. pylori-associated carcinogenesis.

OBJECTIVES: The purpose of this study was to examine whether Symptom Management Module-Korean Brief Version(SMM-B) is effective as a psychosocial treatment of the inpatients with chronic schizophrenia. We also questioned which of demographic and clinical characteristics could be predictors of differential treatment response. METHODS: The subjects were composed of 30 inpatients with chronic schizophrenia, who were trained with weekly session of SMM-B for 5 weeks. Before and after the training, the level of psychopathology, knowledge about schizophrenia were assessed as dependent variables by using Clinical Global Impression(CGI) and Scale to Assess Unawareness of Mental Disorder(SUMD). RESULTS: Overall, patients showed improvement over the treatment period on psychopathology as well as knowledge about psychosis. Total scores of SUMD were changed from 16.9+/-4.0 before training to 12.9+/-4.2 after training(p<0.01) and scores of CGI were improved from 3.7+/-0.9 to 2.8+/-0.8 (p<0.01). However age, gender, years of education, age of onset, duration of illness, duration of admission, numbers of psychiatric admission, and clinical status evaluated by CGI were not correlated with un-awareness of psychosis. CONCLUSION: These results suggest that SMM-B could be a reliable method to improve self-awareness of psychosis in patients with chronic schizophrenia and one of important elements in rehabilitation.

Rapid advances in the technology of gastrointestinal endoscopy as well as the evolution of science have made it necessary for us to continue update in either various endoscopic techniques or state of art lectures relevant to endoscopy. International Digestive Endoscopy Network (IDEN) 2013 was held in conjunction with Korea-Japan Joint Symposium on Gastrointestinal Endoscopy (KJSGE) during June 8 to 9, 2013 at Seoul, Korea. Two days of impressive scientific program dealt with a wide variety of basic concerns from upper gastrointestine (GI), lower GI, pancreaticobiliary endoscopy to advanced knowledge including endoscopic submucosal dissection forum. IDEN seems to be an excellent opportunity to exchange advanced information of the latest issues on endoscopy with experts from around the world. In this special issue of Clinical Endoscopy, we prepared state of art review articles from contributing authors and the current highlights will skillfully deal with very hot spots of each KJSGE, upper GI, lower GI, and pancreaticobiliary sessions by associated editors of Clinical Endoscopy.

This special September issue of Clinical Endoscopy will discuss various aspects of diagnostic and therapeutic advancement of gastrointestinal (GI) endoscopy, explaining what is new in digestive endoscopy and why international network should be organized. We proposed an integrated model of international conference based on the putative occurrence of Digestive Endoscopy Networks. In International Digestive Endoscopy Network (IDEN) 2012, role of endoscopy in gastroesophageal reflux disease and Barrett's esophagus, endoscopy beyond submucosa, endoscopic treatment for stricture and leakage in upper GI, how to estimate the invasion depth of early GI cancers, colonoscopy in inflammatory bowel disease (IBD), a look into the bowel beyond colon in IBD, management of complications in therapeutic colonoscopy, revival of endoscopic papllirary balloon dilation, evaluation and tissue acquisition for indeterminate biliopancreatic stricture, updates in the evaluation of pancreatic cystic lesions, issues for tailored endoscopic submucosal dissection (ESD), endoluminal stents, management of upper GI bleeding, endoscopic management of frustrating situations, small bowel exploration, colorectal ESD, valuable tips for frustrating situations in colonoscopy, choosing the right stents for endoscopic stenting of biliary strictures, advanced techniques for pancreaticobiliary visualization, endoscopic ultrasound-guided biliopancreatic drainage, and how we can overcome the obstacles were deeply touched. We hope that IDEN 2012, as the very prestigious endoscopy networks, served as an opportunity to gain some clues for further understanding of endoscopic technologies and to enhance up-and-coming knowledge and their clinical implications from selected 25 peer reviewed articles and 112 invited lectures.
