Purpose : This study was conducted to identify the peritonitis occurence of CAPD, by which a basis for efficient patient management could be provided. Method: Data were collected by questionnaires and hospital record from 55 people who underwent or were going through CAPD from January 1998 to April 2004 in a university subsidiary hospital kidney department. Result: 1) There were many elderly people of 61 years or above taking up 50.9%, 75% had low levels of education with middle school graduation or less, and the cases where separate individual rooms enabling the exchange of CAPD were not possessed was shown to be 61.8%. 2) With the management feature of CAPD, those who bathed once or less per 7 days made up 60.0%, and 60% washed their hands well before exchanging solutions which meant that 40% did not wash well or just washed moderately, and in terms of CAPD education, the proportion of those receiving education both before and after dialysis was 29.1%. also, with nutrition conditions, cases where the level of serum albumin was lower than 3.0 made up 38.2%, and those who were conducting self CAPD management was 65.5%, and cases where the management was done by the spouse or family members was revealed to be 34.5%. 3) There were Peritonitis occurrences in 40% of cases, and the number of Peritonitis occurrences within the period was 36, with an occurrence rate of $0.65{\pm}0.99$. Also, 66.7% of the causing bacteria were no growth, Gram positive bacteria made up 27.8%, and Gram negative bacteria consisted of 5.5%. 4) No significant difference was found peritionitis occurrence according to general and management characteristics. Lower peritionitis occurrence were shown with those who had spouses or family members conducting CAPD management as opposed to self-managing patients(p=0.037). Conclusion: Elderly patients there needs to be the participation of family or other support resources rather than subjecting them to self-management of solution exchange and entry/exit. Also, The high occurrence rate from Gram positive bacteria is shown so the importance of CAPD management education including bathing and hand washing needs to be emphasized.

Purpose: This study was to examine the reliability and validity of the Korean version of the Cornell Assessment of Pediatric Delirium (CAPD). Methods: For testing the reliability of the Korean version of the CAPD, this study calculated the internal consistency (Cronbach's α) and the Interrater Correlation Coefficient (ICC) by comparing the independent assessment results of three nurses in Pediatric Intensive Care Unit (PICU). For testing the validity of the Korean version of the CAPD, the assessment result of the Korean version of the CAPD compared with that of the Diagnostic and Statistical Manual of Mental Disorders V (DSM-V). Receiver Operating Characteristics (ROC) analysis was used for measuring sensitivity and specificity. Results: Overall interrater reliability of the Korean version of the CAPD, ICC was .98 (95% CI .96~.99). Cronbach's α was .91 for eight items. The concordance between the Korean version of the CAPD and psychiatrist's diagnosis was 90.0%. When the Korean version of the CAPD has the cut point of 9, sensitivity was 93.8%, and specificity was 75.0%. The area under the curve indicated by the ROC analysis was .88. Conclusion: The Korean version of the CAPD showed good reliability and validity. This tool will be useful for pediatric delirium screening and management in Korean PICU.

In connection with the monitoring of the insulation degradation of large power apparatus in order to predict their expected service failures, a statistical treatment, such as phase resolved partial discharge analysis (PRPDA), has been established for the on-line monitoring system during the past decades. However, this method has shown some inconveniences to identify the nature of the PD source in power apparatus. In this regard, a novel approach based on the chaotic analysis (CAPD) is proposed describing the fundamental ideas, outcomes and different viewpoints from the conventional PRPDA. As a model for the possible defects causing sudden failures in service, three types of specimen are prepared. And partial discharge signals, originated from those samples, are measured and analyzed by means of CAPD. Throughout this work, it seems that the correlation between the consecutive PD pulses, depending on the nature of PD, could be clarified by CAPD. Thereffre, it could be considered that the nature of PD source can be identified more distinctively when the CAPD is combined with PRPDA.

Malnutrition is common and the major risk factor of mortality of end stage renal disease (ESRD) patients. The aim of this study is to assess nutritional status of malnutrition patients on dialysis by various methods and compare nutritional parameters of continuous ambulatory peritoneal dialysis (CAPD) patients with hemodialysis patients. 137 patients on dialysis from April 2009 to July 2013 were enrolled. Nutritional parameters of 66 CAPD and 71 hemodialysis patients were investigated by anthropometry, biochemical study, diet analysis and questionnaires. Malnutrition patients were selected by body mass index (BMI), serum albumin and pre-albumin based on International Society of Renal Nutrition and Metabolism (ISRNM) diagnostic criteria for protein-energy wasting and compared with non-malnutrition patients. In comparison of CAPD and hemodialysis patients, most anthropometric values showed no significant difference except total body water (TBW). TBW was lower in CAPD patients (P=0.024). Although serum albumin was slightly higher in hemodialysis patients (P=0.047), pre-albumin were significantly higher in CAPD patients (P=0.000). Serum blood urea nitrogen (BUN) was higher in hemodialysis patients (P=0.000). In diet analysis, Total calorie (P=0.000) and total cholesterol (P=0.012) intakes were higher in CAPD patients. Mean subjective global assessment (SGA) grade was higher in CAPD patients (P=0.003). Several nutritional parameters of CAPD patients were better than hemodialysis patients implying more intensive therapeutic approach may be needed for hemodialysis patients. We have to understand multiple factors contributing malnutrition of ESRD patients and individualized therapeutic approach is needed.

The present study was designed to compare the nutritional status of hemodialysis (HD) and continuous ambulatory peritoneal dialysis (CAPD) patients. Subjects were 58 HD patients (male/female = 29/29) and 33 CAPD patients (male/female = 23/10) undergoing dialysis treatment in Artificial Kidney Unit of Chonbuk National University Hospital. For nutritional assessment, %IBW (ideal body weight), %TSF (tricep skin fold), %MAC (mid arm circumference), %MAMC (mid arm muscle circumference), serum albumin, serum transferrin, TLC (total lymphocyte count), SGA (subjective global assessment) and estimated energy and protein intakes by 1-month food frequency method were used. Between HD and CAPD group, mean age (50 $\pm$ 12 vs. 52 $\pm$ 12 yr), dialysis durations (37 $\pm$ 36 vs. 30 $\pm$ 26 mon), dietary energy intakes (28.3 $\pm$ 9.0 vs. 28.8 $\pm$ 8.6 kcal/kg/day), dietary protein intakes (1.1 $\pm$ 0.4 vs. 1.2 $\pm$ 0.3 g/kg/day) and incidence of co-morbid conditions (69.0% vs. 69.7%) were not significantly different. Data by using SGA showed a higher incidence of malnutrition in CAPD patients (45.6%) than in HD patients (36.2%). %IBW (p < 0.001), %TSF (p < 0.001) and %MAC (p < 0.001) were higher in CAPD patients than were in HD patients. But serum albumin (p < 0.001) and transferrin (p < 0.001) were significantly lower in CAPD patients than were in HD patients. A higher incidence of malnutrition was shown in CAPD Patients than in HD Patients due to different dialysis type. A significant finding was that CAPD showed protein deficient malnutrition and HD did calorie deficient malnutrition. It suggests that an adequate dietary intake considering dialysis type prevents a prevalence of malnutrition.

The purpose of this study was to assess the frequently consumed dish consumption frequencies of continuous ambulatory peritoneal dialysis(CAPD) patients with osteopenia and develop recipes to improve bone mineral density of CAPD. The subjects were 96 CAPD patients with osteopenia(male 39, female 57) (osteopenia group) and 45 CAPD patients with normal BMD(male 24, female 21), matched with key variables(normal group). Fifty dishes(foods) that most frequently consumed were determined and food consumption frequency for each dish(food) for two groups were compared. Osteopenia group showed lower consumption frequency for ice-cream but higher frequency in apple. Of the 50 most frequently consumed dishes(foods), 20 dishes assessed as safe and recommendable for CAPD patients with osteopenia based on the contents of protein and mineral were selected : white boiled rice, white gruel, beef soup, steamed cabbage, roasted dried laver, fried egg, roasted bean-curd, cooked and seasoned bean sprouts, corn-starch jelly, cheese, ice-cream, orange juice, apple, grape, peach, peanut, raw lettuce, raw cucumber, and injulmi rice cake. wenty eight new dishes with modified recipes were developed for CAPD patients. Protein and mineral contents were analyzed for frequently consumed 17 dishes, assessed as modification of recipes are needed. The recipes were modified to decrease P, Na and K contents and to increase protein and Ca contents. Twenty dishes(foods) selected as having reasonable protein and mineral contents ratio or 28 newly developed dishes modified with protein and mineral contents or ratio would be helpful for nutrition education or counseling for CAPD patients with osteopenia. Dishes(foods) suggested in this study would also be useful for all CAPD patients for preventing osteoporosis.

목적 : 지속적 외래 복막투석(CAPD)직후 발생하는 비감염성 호산구성 복막염(eosinophilic peritonitis, EP)의 임상경과 및 검사소견을 분석하고 가능한 원인인자를 확인하고자 하였다. 방법 : 1994년 1월 1일부터 1996년 12월 31일까지 3년간 서울대학교 어린이병원 소아과에서 만성신부전으로 CAPD를 시행한 34명의 환아들을 대상으로 EP의 발생여부에 따른 임상소견, 검사소견, 임상경과 등의 차이에 대하여 후향적 고찰을 하였다. 결과 : 34명의 전체 환아들중 EP가 병발한 예는 7명 (21%) 이었다. EP 발생유무에 따른 연령, 성별, 원인질환 간의 유의한 차이는 없었다. EP는 5례(71%)에서 CAPD 카테타 삽입후 4일 이내에 발생하였고 주증상은 전례에서 투석액의 혼탁이었으며 발열, 복통, 배액장애 등의 소견은 동반되지 않았고 각종 세균에 대한 투석액의 배양검사는 전례에서 음성이었다. 투석액의 혼탁은 항생제 투여 유무와 무관하게 저절로 좋아지는 경과를 보였다. CAPD 시술전의 말초혈액 호산구 증가와 EP의 발생과는 유의한 상관관계가 있었고 (P=0.002), CAPD 시술 전에 혈액투석을 받은 경우에도 혈액투석용 카테터 삽입 후의 말초혈액 호산구 증가와 EP의 발생과는 유의한 상관관계가 있었다 (P=0.016). CAPD 시술 후의 말초혈액 호산구 증가와 EP와는 유의한 상관관계가 없었다. 한편 투석액중 호산구의 정확한 계수를 위하여는 투석액의 cytospin검사가 필요하였다. 결론 : CAPD를 시작한 만성신부전 환아에서 CAPD 카테터 삽입전에 이미 말초혈액 호산구 증가가 있을 경우 초기에 EP의 발생 가능성이 있음을 염두에 두고, 다른 임상증상없이 투석액의 혼탁만 있는 경우 투석액의 cytospin 검사를 시행하여 조기에 EP를 진단함으로써 불필요한 항생제의 투여를 방지할 수 있다.

Massive hydrothorax complicating continuous ambulatory peritoneal dialysis (CAPD) is relatively rare. A 67-year-old male and a 23-year-old female patients during CAPD presented massive pleural effusion. They have been performing peritoneal dialysis due to end-stage renal disease for 8 months and 2 weeks respectively. We injected $^{99m}Tc$-labelled radiopharmaceutiral (phytate and MAA, respectively) into peritoneal cavity with the dialysate. The anterior, posterior and right lateral images were obtained. The studies reveal visible radioactivity in the right chest indicating the communication between the peritoneal and the pleural space. After sclerotherapy with tetracycline, the same studies reveal no radioactivity in the right chest suggesting successful therapy. We think nuclear imaging is a simple and noninvasive method for the differential diagnosis of pleural effusion in patients during CAPD and the evaluation of therapy.

PD phenomena can be regarded as a deterministic dynamical process where PD should be occurred if the local electric field be reached to be sufficiently high. And thus, its mathematical model can be described by either difference equations or differential equations using several state variables obtained from the time sequential measured data of PD signals. These variables can provide rich and complex behavior of detectable time series, for which Chaos theory can be employed. In this respect, a new PD pattern recognition method is proposed and named as 'Chaotic Analysis of Partial Discharges (CAPD)' for this work. For this purpose, six types of specimen are designed and made as the models of the possible defects that may cause sudden failures of the underground power transmission cables under service, and partial discharge signals, generated from those samples, are detected and then analyzed by means of CAPD. Throughout the work, qualitative and quantitative properties related to the PD signals from different defects are analyzed by use of attractor in phase space, information dimensions ($D_0$ and D2), Lyapunov exponents and K-S entropy as well. Based on these results, it could be pointed out that the nature of defect seems to be identified more distinctively when the CAPD is combined with traditional statistical method such as PRPDA. Furthermore, the relationship between PD magnitude and the occurrence timing is investigated with a view to simulating PD phenomena.

Continuous Ambulatory Peritoneal Dialysis (CAPD) has now become an established form of renal replacement therapy in children. Despite of technical improvements, there are various complications in CAPD. We reviewed medical records of children who received CAPD at Seoul National University Children's Hospital in the period between May 1991 and June 2002. Ninety-three procedures of CAPD catheter insertion in 70 patients were included in this study. Complication rate was 64.5%, and CAPD catheter related peritonitis was most common. In conclusion, CAPD catheter related peritonitis develops in considerable number of pediatric patients. Although the peritonitis could be treated with empirical antibiotics therapy, further investigation to prevent complication is required.
