The overall prognosis of Henoch-Schoenlein purpura (HSP) is favorable, but severe nephritis has a high risk of progression to end stage renal failure. Recent studies emphasize the importance of early treatment in children with severe HSP nephritis, but the treatment of severe HSP nephritis still remains controversial due to the rarity of randomized controlled studies in this field. Nevertheless, several intensive therapies, such as intravenous high-dose methylprednisolone pulse, immunosuppressive/cytotoxic drugs, fibrinolytic therapy, anticoagulants, antiplatelet agent and plasma exchange, have been used in children with severe HSP nephritis. In this review, we focus on the treatment of severe HSP nephritis in children.

This article aims to enhance the biodegradability and environment-friendliness of petroleum based biodegradable poly(butylene adipate-co-succinate-co-terephthalate)(PBAST) by blending chemically modified thermoplastic starch(CMPS). CMPS is a kind of bio-based biodegradable resin which is manufactured by reacting starch with maleic anhydride(MA) in the presence of a plasticizer and a free radical initiator. The characteristic properties of PBAST/CMPS blends were investigated by observing their morphology, thermal, mechanical properties, and biodegradability. The good interfacial adhesion between the phases examined by SEM revealed that PBAST/CMPS blends were compatible blends. The tensile strength and elongation decreased with increasing CMPS content, while modulus increased. The biodegradability of the blends was much higher than that of pristine PBAST and increased with increasing CMPS contents.

Purpose: The purpose of this paper was to identify blood pressure, interdialytic weight gain, thirst and intradialytic discomfort in subjects after applying individual low-sodium dialysis fluid (1,2,3 mEq/L) to hemodialysis patients for 12 weeks. Methods: This study was a non-equivalent pre-post design. For 12 weeks, dialysate concentration was maintained at 1 mEq/L or 2 mEq/L or 3 mEq/L based on average sodium concentration of each individual, and the difference was compared after applying individually. Results: Change in blood pressure significantly decreased in the group where in pre-hemodialysis systolic pressure decreased the gradient of sodium concentration in serum sodium and dialysis solution by 2mEq/L. Interdialytic weight gain, and thirst showed significant decrease in all three groups. But in all three groups, intradialytic discomfort among dialysis showed no significant changes. Conclusion: Although application of low sodium dialysis fluid showed no change in intradialytic discomfort, lowered blood pressure, thirst, and interdialytic weight gain, which could be used for individual showing increased interdialytic weight gain and increased blood pressure. There is need for continued study on this.

Purpose : This descriptive survey aims to identify the prevalence of factors associated with sarcopenia among hemodialysis patients. Methods : The study subjects were 137 patients with chronic kidney failure undergoing hemodialysis in three artificial kidney centers in B and Y cities. Data were collected from August 1 to September 30, 2020, using the SARC-F (Strength, Assistant walking, Rising from a chair, Climbing stairs, Falls) questionnaire, Mini Nutritional Assessment-Short Form (MNA-SF), International Physical Activity Questionnaire (IPAQ-SF), Bioelectrical Impedance Analysis (BIA), and a grip dynamometer. The collected data were analyzed using t-tests, crossover analysis, and logistic regression using the IBM SPSS 23 program. Results : The prevalence of sarcopenia among hemodialysis patients, determined using the SARC-F questionnaire, was 16.1%. The associated factors of sarcopenia among hemodialysis patients were found to be gender (OR=6.44, p =.002), age (OR=1.07, p =.015), nutritional status (OR=10.37, p =.027), and albumin level (OR=0.10, p =.014). These findings are supported by an explanatory power of 46.3% (p =.597). Conclusion : The identified risk factors for sarcopenia in hemodialysis patients were; sex, age, nutritional status, and albumin level. The findings of this study can serve as clinical evidence for the development of an intervention program for preventing and managing sarcopenia in patients undergoing hemodialysis.

The aim of this research article is to investigate the life and educational ministry of friars, focusing on the Dominican friars, along with its influence on parish priests and laymen during late middle Ages. The friars' apostolic life and competent teaching ministry greatly contributed to the faith formation of the laity who desperately sought out sacred truth. In particular, the Dominican friars' teaching of orthodox theology and logical argument gave rise to the conversion of some heretics, including Cathars. In addition, their ministry helped parish priests maintain hold on the essence of the church and their apostolic vocation. Finally, the friars' educational ministry played a significant role in enabling the parish priests to take their responsibilities as confessors, teachers, preachers, and healers of souls.

한의학에서 신장(腎臟)은 단순히 소변을 만들어내는 곳으로 보는 것이 아니라 정력과 생식 활동을 담당하는 곳으로 표현하고 있다. 이러한 신장은 두 개의 강낭콩처럼 생긴 모양을 띄고 있으며 서로 마주 보고 있고 등에 붙어 있어 체내의 조절 기능을 수행하고 있다. 이와 같은 역할을 수행하는 신장에 이상이 발생하면 신부전, 신장염, 신우염 및 부종 등의 신장 질환을 앓게 된다. 따라서 본 논문에서는 신장 기능의 이상 유무를 손쉽게 판단하기 위한 방법으로 음성 분석을 통한 자가 진단법을 제안하고자 한다. 이를 위해 한의학에서 제시하고 있는 신장 질환자에 대한 목소리 패턴을 객관적 지표로 설계하기 위해 정상인과 신장 질환자를 대상으로 음성의 고저(高低)에 해당하는 분석 요소를 적용하여 피실험자 집단간의 비교, 분석을 실험으로 입증하고자 한다.

Hemarthrosis occurring after arthroscopic surgery for lesions of the shoulder joint is a very rare complication that can develop due to an injury to the blood vessels when an anterior portal is formed. This is a complication that rarely develops in patients who are taking antithrombotic drugs or who do not have associated diseases, such as thrombocytopenia. We report a case of hemarthrosis that occurred after performing arthroscopic surgery to repair a rotator cuff tear in a patient with a stenosis in an arteriovenous fistula for hemodialysis in the ipsilateral upper arm.

Purpose : The urinary mass screening program for the detection of proteinuria in school aged population has been performed in Seoul since 1981. Systematic evaluation in corporation with the Seoul School Health Center for students with proteinuria identified in the mass screening has been performed from 1987. The results of urinary mass screening up to 1994 was reported. I report here the results of urinary mass screening from 1995 to 1997 and compare them with previous results and attempt to reveal the significance of urinary mass screening. Objects and Methods : In the 3-year period between 1995 and 1997, annually about 460,000 students comprising 3 different age groups; 5th grade of elementary school, 2nd grade of middle school and 2nd grade of high school were chosen, corresponding to the approximate ages of 11, 14, and 17 years, respectively. These subjects accounted for 26% of total school aged children in Seoul. The screening program was carried out in 3 steps. The 1st test was performed with dipstick at school and the 2nd at the Seoul School Health Center. Those students who showed proteinuria in the 1st and 2nd tests were referred to the hospital. Laboratory examinations including renal biopsies were performed to those students with pathologic proteinuria to clarify the incipient renal diseases. Results : 1) The prevalence of asymptomatic proteinuria was 0.28% in the 1st test. It peaked at the group of 14 years old as 0.34%, compared with 0.26% at the group of 11 years old and 0.24% at the group of 17 years old. It reached to 0.26% in male and 0.30% in female. 2) 25 percent of those having proteinuria at the first test were positive at the second test. 3) The proportion of patients with proteinuria by 3rd test were as follows; 25% of transient proteinuria, 55% of orthostatic proteinuria, 6% of constant proteinuria, 12% of proteinuria with hematuria, and 2% of transient proteinuria with isolated hematuria. Pathologic proteinuria were totaled as 20%. The prevalence of renal diseases among the age group of 7-18 years old was estimated to be 1.4 per 10,000. 4) Renal biopsy performed on 38 children with proteinuria at the third test revealed IgA nephropathy in 17(44%), focal segmental glomerusclerosis in 5(13%), minimal change disease in 4(11%), membranoproliferative glomeronephritis in 3(8%), $Henoch-Sch\"{o}nlein$ purpura nephritis in 3(8%), and others in 6(16%). Therefore, the prevalence of IgA nephropathy among the age group of 7-18 years old was estimated to be 0.64 per 10,000. 5) The prevalence of chronic renal failure was estimated to be 5.7 per 1 million of 7 to 18 years age group. Conclusions : 1) The prevalence of proteinuria in the first screening test was 0.28% and finally only 5% of them showed the pathologic proteinuria at the third test. 2) The prevalence of IgA nephropathy and chronic renal failure were 0.63 per 10,000 and 5.7 per 1 million, respectively among school-aged children in Seoul.
