OBJECTIVES: In previous studies, significant correlations between depression or somatization and the mode of anger expression were reported. However few studies were done in psychiatric patients, while some evidences were found that anger expression as well as anger suppression were related to development of somatization. This study aimed to investigate the relationship of the state-trait anger and the mode of anger expression to depression and somatization in psychiatiric patients. METHODS: The depression and somatization questionnaire of SCL-90-R and Korean Adaptation of the State-Trait Anger Expression Inventory were administered to 53 psychiatric patients and 59 normals. The relationship of anger to depression and somatization was analyzed by correlation and regression analyses. RESULTS: In comparison with the normal control group, the psychiatric patient group showed significant differences on trait anger temperament but no significant differences on other anger variables. In regression analysis, the anger-in score was related to depression and somatization. However, the degree of explanatory power was higher in depression than in somatization. In the case of analyzing the state-trait anger, anger-in was significant predictor variable for depression in psychiatric patient group. CONCLUSION: These results suggested that anger-in is the important factor in the onset of depression and somatization. Rather than the relationship of anger-in and somatization, the relationship of anger-in and depression is higher; therefore the caution is necessary in the interpretation of previous studies. The relationship of anger-in to depression and somatization may have important implications for psychotherapy.

OBJECTIVE: This study was aimed to determine effectiveness and tolerability of Osmotic-controlled Release Oral delivery (OROS) methylphenidate (MPH) and its optimal dose administered openly over a period of up to 12 weeks in drug naive Korean children with ADHD. METHODS: Subjects (n=143), ages 6 to 18-years, with a clinical diagnosis of any subtype of ADHD were recruited from 7 medical centers in Korea. An individualized dose of OROS-MPH was determined for each subject depending on the response criteria. The subjects were assessed with several symptom rating scales in week 1, 3, 6, 9 and 12. RESULTS: 77 of 116 subjects (66.4%) achieved the criteria for response and the average of optimal daily dose for response was to 30.05+/-12.52 mg per day (0.90+/-0.31 mg/kg/d) at the end of the study. Optimal dose was not significantly different between ADHD subtypes, whereas, significant higher dose was needed in older aged groups than younger groups. The average of optimal daily dose for response for the subjects aged above 12 years old was 46.38+/-15.52 per day (0.81+/-0.28 mg/kg/d) compared to younger groups (p<0.01). No serious adverse effects were reported and the dose did not have a significant effect on adverse effects. CONCLUSION: Optimal mean dose of OROS-MPH was significantly different by age groups. Higher dose was needed in older aged groups than younger groups. Effectiveness and tolerability of OROS-MPH in symptoms of ADHD is sustained for up to 12 weeks.

Streptococcus bovis (S. bovis) organisms, part of the gastrointestinal normal flora are gram-positive group D streptococci that may be misidentified as enterococci or viridans streptocci. The most important clinical infections caused by S. bovis are bacteremias and endocarditis. S. bovis causes 27% of the episodes of streptococcal native valve endocarditis. Besides, it has been known that there is a association between S. bovis bacteremia and underlying malignancy of the colon. After this association was demonstrated by Klein in 1977, many cases have been reported. But, it is not clear if S. bovis plays an etiologic role in carcinoma of colon or merely a marker for the disease and cases from Korea have rarely been reported. Therefore, we report one case that two synchronous colon cancers, the one on ascending colon and the other on sigmoid colon is accompanied by S. bovis endocarditis.

BACKGROUND/AIMS: Capsule endoscopy (CE) has become a valuable modality for the detection of small bowel lesions. The usefulness of CE for obscure gastrointestinal (GI) bleeding has been established with an overall diagnostic yield of 60%. It is unknown whether CE is of equal value in all the patients or of greater benefit in selected groups in Korea. We evaluated the factors that affect the diagnostic yields of CE in patients with obscure GI bleeding. METHODS: CE was performed in 126 consecutive patients [74 men and 52 women mean age : 52.5 years (25-75 yrs), 23 with active bleeding] with obscure GI bleeding between September 2002 and July 2004. Patients were divided into two groups: those with documented bleeding lesions and those with non specific CE findings. We analyzed the clinical characteristics and other parameters that influenced the diagnostic yields of CE. RESULTS: A definite or probable cause for obscure GI bleeding was found in 69% (80/116) of the patients. NSAID induced ulcer (16.4%) and angiodysplasia (12.1%) were the most common diagnoses. In patients with active bleeding, the diagnostic yield was significantly greater than that of the patients with occult bleeding (80% vs. 68.3%, p<0.05). However, there was no significant difference in parameters between patients with abnormal CE and those with normal CE in respect to gender, age, previous bleeding history, need for transfusion, cecum imaging, and bowel preparation. CONCLUSIONS: The diagnostic yield of CE in patients with obscure GI bleeding is 69%. It is significantly higher in patients with active bleeding.

BACKGROUND/AIMS: Gastroesophageal reflux disease (GERD) is known to be one of the contributing factors to cause epigastric soreness, which we often experience after intake of flour-based meals. The aim of this study was to evaluate gastroesophgeal reflux (GER) and its mechanism according to intake of different ingredients of meals. METHODS: We investigated the effect of meals of different ingredients on the lower esophageal sphincter (LES) pressure, the frequency of transient LES relaxation (tLESR) and GER in seven healthy volunteers. The meals used in this study were either rice cakes or flour cakes, which were isocaloric and isovolumetric. A mylohyoid electromyogram, LES pressure and esophageal pH were simultaneously recorded for 3 hours after ingestion of each meal on two different occasions. RESULTS: There was no significant difference in incidence of GER between two meals. CONCLUSION: The intake of isocaloric and isovolumetric meals of either flour or rice cake did not result in significant discrepancies in frequency of GER. The increase in the frequency of swallow- and strain-associated GER observed in the case of a flour cake may be caused by reduced LES pressure after ingestion.
