OBJECTIVES: Some emotional components, such as self-esteem, depression and anxiety, have been reported to be associated with paranoia in non-clinical population and schizophrenia patients. The aim of this study was to investigate the correlation between self-esteem and paranoia in healthy controls, in ultra-high risk for psychosis and schizophrenia patients. METHODS: 34 subjects with recent onset schizophrenia, 36 subjects with ultra-high risk for psychosis, and 44 healthy volunteers participated in this study. A detailed assessment was made of the paranoia, self-esteem, depression, and anxiety. RESULTS: In all three groups, there were a negative correlation between paranoia and self-esteem, and positive correlations between paranoia and depression and anxiety. In healthy control, lower self-esteem showed a trend to predict higher paranoia, and in ultra-high risk for psychosis, this trend tern on statistically significant level, and in recent onset schizophrenia group, this correlation was disappeared. CONCLUSION: The individual who have lower self-esteem showed higher paranoia tendency under delusional level, but after formation of persecutory delusion, the tendency was disappeared. This result supports the hypothesis that persecutory delusions are a defense against negative affective process.

BACKGROUND: Oxygen free radicals have been implicated as a cause of deleterious effects in the setting of coronary reperfusion, and they are believed to be generated by the xanthine oxidase system, from activated neutrophiles and from mitochondria. We evaluate the contribution of mitochondria to the production of oxygen free radicals and clarify the mechanism of cellular damage in ischemic reperfused hearts. METHODS: Mitochondria isolated from the ischemic rabbit hearts were incubated in the reaction conditions with different oxygen tensions. Generation of superoxide anion and activities of defensive enzymes aginst oxidative stress were mesured. RESULTS: Superoxide anion genertion by mitochondria incubated in 21% oxygen condition were 0.54+/-0.09 and 0.27+/-0.04(O2./min/mg protein) in ischemic mitochondria and in control respectively(P<0.05). Activites of defensive enzymes against oxidative stress, superoxide dismutase and glutathione peroxidase, were significantly reduced in mitochondria isolated from either ischemic or reperfused hearts. With the lapse of respiration in 21% oxygen condition, ADP-stimulated state 3 oxygen consumption(306.4+/-31.5 vs 214.4+/-11.4n atoms O/min/mg protein) at 30 minutes, P : O ratio and phosphorylation rate were significantly decreased in ischemic mitochondria. CONCLUSION: Elevation of oxygen free radical generation as well as the reduction of defensive enzyme activities in ischemic reperfused mitochondria are injurious to mitochondrial respiratory function. It may contribute to the mechanism of cellular damage in ischemic reperfused hearts.

BACKGROUND: Urinary tract infections (UTIs) are the most frequent nosocomial infections and are frequently associated with indwelling urinary catheters. It is known that adherence to standard infection control measures for urinary catheters can reduce UTIs in hospitals. This study was performed to evaluate the effect of education in reducing catheter-related UTIs (CR-UTIs) in intensive care units (ICUs) of a university hospital. METHODS: CR-UTIs were prospectively monitored for all patients with indwelling urinary catheters in ICUs from July 2006 through December 2007. Recommendations based on previously known guidelines for catheter insertion, catheter management, and specimen collection to prevent CR-UTIs were formulated and educated in March 2007. Knowledge and adherence level were evaluated before and after educating healthcare workers about the recommendations using questionnaire. Changes in knowledge and adherence level before and after education were compared by Chi-square test. Changes in the rate of CR-UTIs and urinary catheter utilization ratios were also analyzed by Fisher's exact test. RESULTS: After education, knowledge level of and adherence level to most of the recommendations were improved significantly. The rate of CR-UTIs significantly decreased by 48% from 7.43/1,000 catheter-days before intervention to 3.87/1,000 catheter-days after intervention (P=0.02). CONCLUSION: Surveillance for nosocomial infections and education for standard infection control measures are very important in preventing CR-UTIs in ICUs.

Fungal infection has been observed with increasing frequency in recent years because the use of combinations of broad spectrum antibiotics, immunosuppressive agents, and antineoplastic agents is increasing and the survival rate of premature baby is increasing. We experienced a 3 month old male infant with anuria due to bilateral ureteropelvic fungus balls. He was born at 31 weeks gestation period and had been treated with broad spectrum antibiotics for 5 weeks after birth. We removed fungus balls surgically and made nephrostomy bilaterally. And then irrigation of amphotericn B through nephrostomy and systemic amphotercin B injection had performed for 3 weeks. Thereafter fungus balls completely disappeared.

The Gerbode shunt, known as the left ventricle to the right atrial communication, is a rather rare finding, following surgical closure of septal defects. Even though the surgical closure is accepted as a treatment of choice, we report a successful percutaneous transcatheter closure of the Gerbode shunt in a 3-months old baby who weighed 3 kilograms.
