BACKGROUND: The bioincompatability of the conventional peritoneal dialysis can be partly attributed to the presence of GDPs, which are generated during the heat sterilization. Formation of GDPs can be significantly reduced by the use of multi-chamber bag systems because high concentrated glucose is separated from alkaline lactate. In order to investigate whether multi-chamber bag system can improve the in vivo biocompatibility, we performed a randomized, prospective study comparing the multi-chamber bag system with the conventional PD system, measuring CA125 and PIIINP levels in the effluent dialysates as well as the other clinical and biochemical parameters. METHODS: Forty five patients who were stable on CAPD were enrolled randomly assigned to experiment group (n=27), and control group (n=18). Overnight effluent was collected for measurement of CA125 and PIIINP and the other clinical, biochemical parameters were compared including the number of peritonitis, the ultrafiltration volume. RESULTS: In patients treated with the multiple chamber bag system, there were significantly higher levels of CA125 and PIIINP from 1 month. No clinical and biochemical parameters influenced on their levels. The incidence of peritonitis or ultrafiltration volume did not differ between the two groups. CONCLUSION: Using the low GDP solution resulted in a better preservation of peritoneal mesothelial mass and an improvement of local peritoneal homeostasis, which are supposed to contribute to the biocompatibility of peritoneal dialysis fluid.

BACKGOUND: Although the incidence has decreased markedly, mortality from uremic pericarditis still remained high at 8-10% due to hemodynamic compromise. Moreover, it is difficult to diagnose and discriminate from other causes of pericarditis such as tuberculous pericarditis in its early stage. The aim of this study was to analyze the factors that were related to the development of uremic pericarditis and factors that could distinguish it from other causes of pericarditis. METHODS: Eighteen patients who received pericardiocentesis due to uremic pericarditis from 1996 to 2005 in Korea university hospital were enrolled. All patients were diagnosed as severe uremic pericarditis by echocardiography. And as a comparison group, 37 patients with tuberculous pericarditis and 20 patients with malignant pericarditis were also enrolled. Analysis of the factors that were related to the development of uremic pericarditis or comparison of clinical, biochemical factors in uremic, tuberculous or malignant pericarditis were also done. RESULTS: In uremic pericarditis, the proportion of patients with peritoneal dialysis was higher (55.6%). The amount of pericardial effusion showed a positive correlation with the duration of dialysis, whereas showed negative correlation with hemoglobin and cholesterol levels. Pericardial fluid ADA was significantly higher in tuberculous pericarditis and pericardial fluid glucose was higher in uremic pericarditis. No specific factors that were related to the development of pericardial tamponade were identified. CONCLUSION: The development of severe uremic pericarditis might be related to poor nutritional status. In the early stage, ADA and glucose levels in pericardial fluid could be useful in distinguishing uremic pericarditis from tuberculous pericarditis. Prospective studies that enroll large patient population can be helpful in identifying factors that are related to the development of uremic pericarditis or tamponade.

BACKGROUND AND OBJECTIVES: From the view point of the molecular aspects, the fate of long standing pressure and volume overloaded atrium in severe MR has not been evaluated. This study was performed to elucidate whether apoptosis of right atrial myocytes is related to atrial changes. SUBJECTS AND METHODS: The medical records of 16 patients (M: F=8: 8, mean age=52+/-12), with severe MR having undergone valve replacement surgery, were retrospectively reviewed. The subjects were divided into 2 groups according to the duration of their symptoms (group I, symptom duration less than 12 months, n=10 and group II, more than 12 months, n=6). Using the atrial myocardium specimens obtained during surgery, TUNEL assays and immunohistochemical staining were performed for the expressions of Fas, Bax and the Bcl family. RESULTS: Apoptotic indices of TUNEL assay were 31.1+/-12.6 and 4.9+/-4.3% in groups I and II, respectively (p<0.01). The Fas expressions were 42.1+/-14.4 and 27.8+/-10.5% in groups I and II, respectively (p<0.05), but in group I, with atrial fibrillation (AF), was 49.3+/-6.9%, which was higher than the 29.2+/-12.5% in group I without AF and group II (p<0.001). The Bax expression in group I patients with a left atrial size less than 4 cm was 19.2+/-10.7%, which was higher than the 7.2+/-6.2% in group I with a left atrial size more than 4 cm and group II (p<0.05). CONCLUSION: Programmed cell death of the atrial myocardium, in severe MR, might be an early molecular pathological change rather than the late sequelae. The causality between programmed cell death and electrical and structural changes of the atrium should be further investigated.

OBJECTIVES: The aim of this study was to evaluate the reliability and validity of the Korean Version of the Diagnostic Interview Schedule for Children Version IV(DISC-IV), a highly structured diagnostic interview used to assess more than 30 psychiatric disorders in children and adolescents. METHODS: A total of 91 study subjects, including 67 subjects who visited the child and adolescent psychiatry outpatient clinic at our institution and 24 community-based subjects, were assessed using the Korean Version of the DISCIV. Clinical diagnosis was used as a gold standard for the examination of the validity of the DISC-IV. Forty-four of the study subjects were randomly selected for test-retest reliability measurement. RESULTS: The validity of the Korean Version of the DISC-IV showed kappa values ranging from 0.25 to 0.40 in the clinical sample and 0.65 to 1.00 in the community sample. The sensitivities varied according to the diagnostic categories, but the specificities were excellent for all diagnostic entities. CONCLUSION: The Korean Version of the DISC-IV showed good reliability and validity in Korean children and adolescents. The Korean Version of the DISC-IV might be a useful tool for assessing psychiatric disorders in children and adolescents.
