Purpose: The purpose of this study was to develop a standardized education protocol for peritoneal dialysis patients. Methods: First, the demand for education was investigated from the 27 patients on peritoneal dialysis and 16 guardians, and later, the standardized nursing education protocol has been developed through the comprehensive literature review and the critical analysis of the related studies. Contents validity and applicability have been tested through the expert group survey. Results: The standardized peritoneal dialysis nursing education protocol with 9 areas and 20 items has been developed. The content validity for timing and duration, contents, method, and place of education proposed by the protocol were all above than 0.8. In terms of the applicability of the protocol, the experts scored between 4.20 to 4.93 for all items except one. The item on home visit education acquired the lowest applicability score, because there might exist potential restrictions in visiting patient's home. Conclusion: The standardized education protocol developed in this study turned out to be adequate by representing high content validity for all items and the applicability also was high except the item on home visit education. Further researches to test the effects of this education protocol should be done.

Fibrosis is characterized by excessive accumulation of extracellular matrix components. The fibrotic process ultimately leads to organ dysfunction and failure in chronic inflammatory and metabolic diseases such as pulmonary fibrosis, advanced kidney disease, and liver cirrhosis. Idiopathic pulmonary fibrosis (IPF) is a common form of progressive and chronic interstitial lung disease of unknown etiology. Pathophysiologically, the parenchyma of the lung alveoli, interstitium, and capillary endothelium becomes scarred and stiff, which makes breathing difficult because the lungs have to work harder to transfer oxygen and carbon dioxide between the alveolar space and bloodstream. The transforming growth factor beta (TGF-β) signaling pathway plays an important role in the pathogenesis of pulmonary fibrosis and scarring of the lung tissue. Recent clinical trials focused on the development of pharmacological agents that either directly or indirectly target kinases for the treatment of IPF. Therefore, to develop therapeutic targets for pulmonary fibrosis, it is essential to understand the key factors involved in the pathogenesis of pulmonary fibrosis and the underlying signaling pathway. The objective of this review is to discuss the role of kinase signaling cascades in the regulation of either TGF-β-dependent or other signaling pathways, including Rho-associated coiled-coil kinase, c-jun N-terminal kinase, extracellular signal-regulated kinase 5, and p90 ribosomal S6 kinase pathways, and potential therapeutic targets in IPF.

Familial juvenile hyperuricemic nephropathy is an autosomal dominant disease characterized by progressive renal disease and hyperuricemia or gout, affecting young people of either sex equally. There are two biochemical markers of this disorder. The first is hyperuricemia disproportionate to the degree of renal dysfunction; the second is a grossly reduced clearance of uric acid relative to creatinine, dispropotionate to age, sex and degree of renal failure. We experienced 2 family members with hyperuricemia. One family member, a 13-year-old girl who had suffered from tophaceous gout and chronic renal failure. Her younger brother also had hyperuricemia and moderately reduced renal function. Their urinary excretion fractions of uric acid($FE_{uric\;acid}$) were reduced and renal biopsy specimens showed interstitial fibrosis with tubular atrophy and interstitial urate crystal deposition. We have treated these two patients with allopurinol but we have done renal transplantation because she progressed to end stage renal disease at 16 year old age.

The DMSA scan is a useful radiologic study in diagnosis of morphologic and functional diseases of kidney. We evaluated the distribution of sex and age, clinical manifestations, diagnosis, combined diseases, treatment and prognosis of the 61 patients with non-functioning kidney(no isotope uptake or uptake below 5% in DMSA scan) who admitted in our hospital from 1980 to 1995. The proportion of patients under 1 year old age was 46%. Sex ratio was 1.4:1 with male predominance. Most diagnosis of non-functioning kidneys were congenital such as multicystic dysplastic kidney, hydronephrosis due to ureteropelvic junction obstruction, renal agenesis and renal hypoplasia. In order of frequency thirty one percent of them were previously detected on antenatal ultrasonogram. Treatment consisted of operation in 47.5%, mostly nephrectomy and 32.8% of patients were followed up at OPD base without definite treatment. The most common combined diseases was hydronephrosis, in 4patients who had both kidneys inveloved progressed to chronic renal failure, but the prognosis in most cases were good. It is important to evaluate renal diseases in perinatal periods, and we believe that highly sensitive diagnostic study contribute to early treatment plan and thus to good prognosis.

Brown tumors also called as osteoclastomas, are rare nonneoplastic lesions that arise in the setting of primary or secondary hyperparathyroidism. Parathyroid adenomas or hyperplasia constitute the major Brown tumor source in primary hyperparathyroidism while chronic renal failure is the leading cause in secondary hyperparathyroidism. Most of the patients with the diagnosis of primary hyperparathyroidism present with kidney stones or isolated hypercalcemia. However, nearly one third of patients are asymptomatic and hypercalcemia is found incidentally. Skeletal involvement such as generalized osteopenia, bone resorption, bone cysts and Brown tumors are seen on the late phase of hyperparathyroidism. The symptoms include axial pain, radiculopathy, myelopathy and myeloradiculopathy according to their locations. Plasmocytoma, lymphoma, giant cell tumors and metastates should be ruled out in the differential diagnosis of Brown tumors. Treatment of Brown tumors involve both the management of hyperparathyroidism and neural decompression. The authors report a very rare spinal Brown tumor case, arisen as the initial manifestation of primary hyperparathyroidism that leads to acute paraparesis.

Purpose: This study was conducted to examine the effects of ethyl chloride spray during arteriovenous fistula puncture on pain, depression, and noncompliance in hemodialysis patients. Methods: This study used a randomized controlled trial design on adults with chronic renal failure who received hemodialysis treatment through arteriovenous fistula. Ethyl chloride spray was applied to 20 subjects in the experimental group during arteriovenous fistula puncture, and a placebo spray was applied to 20 subjects in the control group; the intervention was conducted 12 times for 4 weeks. A total of 33 participants were used in the final analysis. The outcomes were measured using the face pain rating scale, Center for Epidemiological Studies Depression Scale (CES-D), and modified United States Renal Data System tools. Results: As a result of the pre-homogeneity test between the two groups, it was confirmed that the sexes were not homogeneous. Therefore, sex was treated as a covariate and analyzed. Puncture pain was significantly reduced in the experimental group (p<.001). However there was no significant difference between the groups in depression and noncompliance. Conclusion: Ethyl chloride spray was convenient and effective pain management intervention for both hemodialysis patients and medical staff.

Microscopic polyangiitis(MPA) is a systemic necrotizing vasculitis that involves many organ systems including the skin, joint, kidneys, and lungs. In spite of early diagnosis and intensive care, the five-year actuarial patient and kidney survival rates are 65% and 55%. We experienced a case in 7-year-old girl of microscopic polyangiitis presenting with rapidly progressive glomerulonephritis which was confirmed by renal biopsy and positive serum perinuclear antineutrophil cytoplasmic autoantibodies(p-ANCA). The diagnosis of patients first renal biopsy was MPA, p-ANCA-associated crescentic glomerulonephritis. The patients second renal biopsy was done 5 years 6 months later since first renal biopsy, and pathologic diagnosis was chronic sclerosing glomerulonephritis, advanced, due to MPA. We began methylprednisolone pulse therapy, combined with a low dose of cyclophosphamide and plasmapheresis therapy. ACE inhibitor, angiotensin II receptor blocker, and cyclophosphamide were used until now and the patients current age is 14 years old. On admission, the patients laboratory findings showed BUN 117 mg/dL and Cr 2.3 mg/dL, while on the hospital day BUN and Cr values fell to 20.8 mg/dL and 1.6 mg/dL. But renal function was progressed to chronic failure with latest laboratory data BUN 51.7 mg/dL and Cr 3.2 mg/dL. ACE inhibitor, angiotensin II receptor blocker and small dose of immunosuppressant with close observation is the key to maintain the patient survival.

The number of patients is increasing and their mean age is also increasing. Proper dietary adjustments are necessary to prevent protein-calorie malnutrition or complications but it is difficult for dialysis patients to adapt to diet therapy due to stress or anorexia. Education does not consider the individual characteristics, knowledge, dietary inhabit education demands, and initial education. The purpose of this study was to identify dialysis patient's nutrition knowledge and, dietary practice and compare those with nutrition education or counseling demands for providing basic data of desirable nutrition management. The data were collected by a survey consisting of the general characteristics, disease related characteristics, nutrition education and counsel characteristics, level of nutrition knowledge, diet therapy, and nutrition education and counsel demands from the 28th March to 22th July 2017. The total number of subjects were 33 patients among dialysis patients at two tertiary medical institutions and an artificial kidney room at a private hospital in Incheon Gyeonggi. The data collected were analyzed statistically using the SPSS program 23.0, followed by further analyses using frequency analysis, one-way ANOVA, cross analysis, and correlation analysis. The results of the dialysis patients showed that younger (P<0.05), female (P<0.05), abnormal high school diploma (P<0.001) groups had high nutrition scores. In addition, dietary practice and nutrition education and counsel demands showed a positive correlation (P<0.05, P<0.01). In particular, females were higher than males in nutrition knowledge, dietary practice, nutrition education, and counseling demand scores.

BACKGROUND: In patients with acute heart failure (AHF), diastolic dysfunction, especially pseudonormal (PN) or restrictive filling pattern (RFP) of left ventricle (LV), is considered to be implicated in a poor prognosis. However, prognostic significance of diastolic dysfunction in patients with ischemic heart disease (IHD) has been rarely investigated in Korea. METHODS: We enrolled 138 patients with IHD presenting as AHF and sinus rhythm during echocardiographic study. Diastolic dysfunction of LV was graded as ${\geq}2$ (group 1) or 1 (group 2) according to usual algorithm using E/A ratio and deceleration time of mitral inflow, E'/A' ratio of tissue Doppler echocardiography and left atrial size. RESULTS: Patients in group 1 showed higher 2-year mortality rate ($36.2%{\pm}6.7%$) than those in group 2 ($13.6%{\pm}4.5%$; p = 0.008). Two-year mortality rate of patient with LV ejection fraction (LVEF) < 40% ($26.8%{\pm}6.0%$) was not different from those with LVEF 40%-49% ($28.0%{\pm}8.0%$) or ${\geq}50%$ ($13.7%{\pm}7.4%$; p = 0.442). On univariate analysis, PN or RFP of LV, higher stage of chronic kidney disease (CKD) and higher New York Heart Association (NYHA) functional class were poor prognostic factors, but LVEF or older age ${\geq}75$ years did not predict 2-year mortality. On multivariate analysis, PN or RFP of LV (hazard ratio [HR], 2.52; 95% confidence interval [CI], 1.09-5.84; p = 0.031), higher stage of CKD (HR, 1.57; 95% CI, 1.14-2.17; p = 0.006) and higher NYHA functional class (HR, 1.81; 95% CI, 1.11-2.94; p = 0.017) were still significant prognostic factors for 2-year mortality. CONCLUSIONS: PN or RFP of LV was a more useful prognostic factor for long-term mortality than LVEF in patients with IHD presenting as AHF.

Purpose : We analyzed the demogaphic data md clinical course of Korean children with chronic renal failure (CRF) observed between 1990 and 1999. Patients and Methods : Questionnaires were mailed to all children's hospitals ail through the country. We asked for primary renal disease age and serum creatinine levels at first presentation with CRF and end-stage renal disease (ESRD), and modes of renal replacement therapy (RRT). Results : 401 children (254 boys, 147 girls) with CRF, defined as a permanent increase of serum creatinine above 1.2 mg/dl for at least 3 months or until death, were identified. This represents an incidence of 3.68 per million child population per year. Of these patients, 22$\%$ on younger than 5 years, 28$\%$ 5 to 10 years and 50$\%$ 10 to 15 year. Eight five $\%$ of the patients could be classified with a primary renal disease. The most frequent cause is glomerulonephritis (36$\%$), followed by chronic pyelonephritis (21$\%$), renal hrpo/dylplasia (9$\%$), and hereditary nephropathies (7$\%$). Reflux nephropathy (16$\%$) was the most common single cause of CRF. ESRD was reached in 70$\%$ of all patient. 99.3$\%$ of these started RRT. Hemodialysis (HD, 42$\%$), peritoneal dialysis (PD, 35$\%$) and transplantation (TP, 23$\%$) were performed as the initial mode of RRT. A total of 161 TPs were performed (159 first grafts, 2 second grafts). A total of 32 patients died. The main causes of death were dialysis related complication in HD patients and infections in PD patients. Survival rate on any form of RRT was 88.7$\%$ during the mean follow-up period of 37 months. Conclusion Major efforts should be directed toward earlier diagnosis and treatment of reflux nephropathy to prevent occurrence of Of. Dialysis and TP have now become well accepted forms of treatment in Korean children with ESRD.
