A 5-year-old, 2.7 kg, spayed female Scottish Fold cat presented with hematemesis after administration of oral zaltoprofen, a non-steroidal anti-inflammatory drug, by the owner. Diagnostic imaging and blood analyses indicated development of acute kidney injury (AKI) resulting from zaltoprofen ingestion. To correct dehydration and anemic conditions, the cat received intravenous fluid therapy with whole blood transfusion and peroral N-acetylcysteine. Clinical signs resolved, but persistent azotemia was unresolved indicating that AKI could progress to chronic kidney disease. This case suggests that although zaltoprofen may have low adverse effects on humans, administration of zaltoprofen in cats can have serious adverse effects.

Background: To examine survival rates and renal function after partial nephrectomy (PN) and radical nephrectomy (RN) in patients with chronic kidney disease (CKD). Methods: We studied 4,332 patients who underwent PN or RN for pathological T1a-T2N0M0 renal cell carcinoma from 1988 to 2014. Patients were divided into two subgroups of CKD stage I-II and stage III. Kidney function, and survival outcomes were compared between groups. Results: We included 1,756 patients with CKD I-II and 276 patients with CKD III in the final pair-matched analysis. Kidney function was significantly better preserved in the PN than in the RN group among all patients. However, the beneficial effect of PN on kidney function gradually disappeared over time in CKD III patients. The 5-year overall survival (OS) rates after PN and RN differed in patients with CKD I-II disease (99.4% vs. 96.5%, respectively, P = 0.015). The 5-year OS rates after surgery were not affected by mode of nephrectomy in CKD III patients (97.8% vs. 93.5%, P = 0.103). The 5-year cancer-specific survival rates did not differ between treatment groups in all CKD stage. Cox hazard analysis showed that the operative method was a significant factor for OS in CKD I-II patients (hazard ratio [HR], 0.320; confidence interval [CI], 0.122-0.840; P = 0.021). However, PN was not beneficial in terms of OS in CKD III patients (HR, 0.395; CI, 0.086-1.172; P = 0.117). Conclusion: PN is associated with a higher OS rate and better kidney function in patients with preoperative CKD stage I and II, but not in those with CKD stage III.

Purpose : To report the decreasing indicence of HBV(Hepatitis B virus)-associated membranous nephropathy in children after HBV vaccination and to elucidate the clinical course and treatment strategies of IMN(Idiopathic membranous nephropathy). Methods : We retrospectively reviewed the clinico-pathological findings of HBV-MN and IMN patients who underwent a renal biopsy from 1986 to 2005. We compared the HBV-MN and the IMN groups and the remission and the non-remission groups of patients with IMN. Results : Among 24 cases of MN patients, HBV-MN comprised 6 cases(25%) and IMN 18 cases(75%). Clinical masnifestations were nephrotic syndrome(3 cases, 50%), nephritic syndrome(1 case, 16.7%), asymptomatic(2 cases, 33.4%) in the HBV-MN group, asymptomatic(10 cases, 55.5%), nephrotic syndrome(5 cases, 27.8%), and gross hematuria(3 cases, 16.7%) in the IMN groups. From 1996 to 2000, there were 2 cases(28%) of HBV-MN and 5 cases(72%) of IMN. After 2001 all 10 cases were IMN. In the HBV-MN group, 4 cases(66.7%) received interferon and 1 cases received methylprednisolone pulse therapy. In the IMN group, 16 cases(88.9%) received methylprednisolone, 8 cases(44.4%) were in complete remission, 2 cases(11.1%) were in partial remission, 2 cases(11.1%) were in chronic renal failure, and 5 cases(27.8%) were lost to follow-up with sustained proteinuria, 1 case(5.6%) continued to have frequent relapse of nephrotic syndrome without renal insufficiency. In the comparison between remission and non-remission groups, nephrotic range proteinuria and hypertension were more significantly common in the non-remission group(P<0.05). Conclusion : With HBV vaccination, HBV-MN has decreased markedly. IMN is a rare glomerular disease in children. Because the prognosis for patients with nephrotic range proteinuria is poor this group needs more aggressive treatment.

Background: This study aimed to evaluate the impact of the treatment modality on post-procedural acute kidney injury (AKI) and other clinical outcomes in patients with advanced chronic kidney disease who underwent surgical or transcatheter aortic valve replacement (AVR). Methods: A total of 147 patients with advanced chronic kidney disease (stage 3 to 5) who underwent isolated surgical AVR (SAVR group; n=70) or transcatheter AVR (TAVR group; n=77) were retrospectively studied. Postprocedural AKI was defined according to the RIFLE definition (an acronym corresponding to the risk of renal dysfunction, injury to the kidney, failure of kidney function, loss of kidney function, and end-stage kidney disease). Factors associated with postoperative complications and mortality were analyzed using multivariable logistic regression models and Cox proportional hazard models. Results: Postprocedural AKI occurred in 17 (24.3%) and 6 (7.8%) patients in the SAVR and TAVR groups, respectively (p=0.006). Multivariable analyses demonstrated that the SAVR group had higher risks of AKI (odds ratio [OR], 5.63; 95% confidence interval [CI], 1.85-17.73; p=0.002) and atrial fibrillation (OR, 16.65; 95% CI, 4.44-62.50; p<0.001), whereas the TAVR group had a higher risk of permanent pacemaker insertion (OR, 5.67; 95% CI, 1.21-26.55; p=0.028). The Cox proportional hazard models showed that the occurrence of AKI, contrary to the treatment modality, was associated with overall survival. Conclusion: In patients with chronic kidney disease, the risk of postprocedural AKI might be higher after SAVR than after TAVR.

Due to its efficacy and tolerability, low dose oral methotrexate (MTX) therapy has been widely used for treatment of rheumatoid arthritis (RA). However, it can rarely cause serious, life-threatening hematologic toxicities, such as pancytopenia. We report here on two patients with chronic kidney disease (CKD), who developed severe pancytopenia after 5 years (cumulative dose 1,240 mg) and 4 years (cumulative dose 1,320 mg) of low dose MTX therapy for treatment of RA, respectively. Both patients presented with renal insufficiency, hypoalbuminemia, concurrent use of nonsteroidal anti-inflammatory drugs, and elevated mean corpuscular volume of red blood cells (RECs), all of which are known as risk factors of MTX-induced pancytopenia. Despite receiving treatment, which included REC and platelet transfusions, antibiotic therapy, granulocyte colony stimulating factor, and leucovorin rescue, one patient died of sepsis. Based on our case study, prompt investigation of risk factors associated with MTX toxicity is required for all patients receiving MTX therapy. MTX treatment, even at a low dose, should be discontinued in patients with advanced CKD.

aortoiliac pattern, Group II; femoropopliteal pattern and Group g; tibioperoneal pattern. A majority of patients belonged to group I [27 cases], 8 patients came under group II .and none in group g. Thirty patients underwent bypass operation with autogenous saphenous vein or synthetic graft with or without concomitant lumbar sympathectomy. Remaining 5 patients were operated on with sympathectomy only, Bypass procedures were anatomic bypass in 22 cases: aortoiliac artery bypass in 11 cases, femoropopliteal artery bypass in 10 cases, sequential femoropopliteal artery bypass in one case and extra-anatomic bypass in 8 cases, axillary-bifemoral artery bypass in one case and femorofemoral artery bypass in 7 cases. Postoperative complications which mainly composed of superficial wound infection[5 cases] which were treated without any significant sequel in all cases and thrombosis[2 cases]. Three patients died whose causes of death were acute renal failure in 2 cases and myocardial infarction in other, The overall patency, rate was 70Zo in 5 years. In conclusion, the clinical pattern and operative outcome were similar to he western pattern and all cases of death did not related to operative procedures and ischemic symptoms were relieved by bypass operations except several cases. I think and recommend that all patients suffering chronic arterial insufficiency by atherosclerosis obliterans ought to be managed with urgent and adequate operative procedure.

목 적 : MPGN은 소아에서는 11년 이내에, 성인에서는 8년 이내에 50%가 사망하게 되는 불량한 예후를 지닌 만성신장병중의 하나이다. 한국에서는 1998년부터 학교집단뇨검사가 법으로 제정되어 시행되었다. 우리는 학교집단뇨검사를 통해 진단된 무증상의 막증식성 사구체신염과 증상이 있는 막증식성 사구체신염의 예후를 비교하였다. 방 법 : 1996년 1월부터 2005년 12월까지 본원 소아과에 입원하여 경피적 신생검 시행 후 병리조직학적 검사상 제 1형 MPGN으로 진단 받고 스테로이드 단독 또는 cyclosporine과 함께 또는 스테로이드만 단독으로 투여받고 있는 환자 18명의 특징과 예후를 분석하였다. 추적 관찰된 기간은 평균 6.3년이었다. 18명의 환자중에 7명의 환자는 학교집단뇨검사를 통해 진단된 환자이고, 11명의 환자는 진단당시 신증후군이나 급성신염, 육안적 혈뇨를 보이는 환자들이었다. 결 과 : 학교집단뇨검사로 진단된 환자들 가운데 남자는 4명이고, 여자는 3명이었다. 이들의 평균나이는 12.6세였다. 학교집단뇨검사에서 4명의 환자는 혈뇨와 단백뇨를 보였고, 1명의 환자는 단백뇨만 보였으며, 2명의 환자는 혈뇨만 보였다. 이들 가운데 3명이 진단 당시 혈청보체치가 감소하여 있었다. Methylprednisolone 충격요법 후에 5명의 환자(72%)가 혈뇨나 단백뇨없이 관해하였으며, 신기능이 저하된 환자는 한명도 없었다. 학교집단뇨검사를 받지 않은 그룹 가운데 남자는 9명이었고, 여자는 2명이었다. 이들의 평균나이는 14.4세였다. 진단 당시 7명의 환자는 신증후군 소견을 보였고, 3명의 환자는 육안적 혈뇨를 보였고, 1명의 환자는 현미경적 혈뇨와 함께 급성신부전의 소견을 보였다. 이들 가운데 진단 당시 혈청보체치가 감소하여 있던 환자는 5명이었다. 그리고 4명의 환자(36%)가 관해를 이루었으며, 1명의 환자는 복막투석을 필요로 하였으며, 3명의 환자에서 신기능이 저하되었으며 이 중 1명의 복막 투석을 필요로 하였다. 결 론 : 위의 사실들을 확실히 하기 위해서는 장기간의 연구가 필요하겠지만, 우리의 연구는 학교집단뇨검사를 통한 조기진단과 스테로이드 치료가 1형 막증식성사구체신염 환아의 예후에 도움이 될 것임을 보여주었다.

Purpose: The purpose of this study was to compare differences in spiritual needs (SNs) and factors influencing SNs between patients with progressive terminal kidney disease and their family caregivers. Methods: An explorative comparative survey was used to identify the SNs of patients (N=102) with progressive terminal kidney disease undergoing hemodialysis and their family caregivers (N=88) at a general hospital located in Seoul, South Korea. The data were analyzed using descriptive statistics, the chi-square test, the independent t-test, one way analysis of variance, the Scheffe test, and multiple regression with dummy variables. Results: The SNs among family caregivers were higher than in the patient group. SNs were higher among those who were religious in both groups. Loving others was the highest-ranked subdimension in the patient group, followed in descending order by maintaining positive perspective, finding meaning, Reevaluating beliefs and life, asking "why?", receiving love and spiritual support, preparing for death, and relating to God. In the family group, the corresponding order was maintaining positive perspective, loving others, finding meaning, receiving love and spiritual support, preparing for death, relating to God, and asking "why?". The factors that had a negative influence on the level of SNs were not being religious in the patient group and having only a middle school level of education in the family group. Conclusion: The results of this study may serve as evidence that spiritual care for non-cancer patients' family caregivers should be considered as an important part of hospice and palliative care.

Purpose: Hepatocellular carcinoma is the 3rd leading cause of cancer death in Korea and its prognosis is very poor. We aimed to investigate the clinical characteristics of terminal patients with hepatocellular carcinoma on admission into a hospice unit, and to know if they had received appropriate hospice and palliative care. Methods: We retrospectively reviewed the medical records in 62 patients with hepatocellular carcinoma who had admitted, received palliative care, and died in a hospice unit between January 2003 and December 2005. Results: The median age of patients was 56.5 years with 50 men(80.65%) and 12 women(19.35%) and gender ratio(male to female) was 417. Child-Pugh class A, B, and C were 6(9.68%), 22(35.38%), and 34(58.84%) respectively. We divided the patients into two groups and compared, the terminal HCC patients with class C as group I and those with class A & B as group 2. The median time from hospice referral to death was significantly short in group 1 with 15.5 days compared to group 2 with 53 days. Statistically more prevalent symptoms in group I were ascites, dyspnea, peripheral edema, and hepatic encephalopathy with abnormal laboratory findings (jaundice, hypoalbuminemia, or renal insufficiency). There, however, was no significant difference in complications and managements during admission between group 1 and 2. Conclusion: Most terminal HCC patients were often accompanied with chronic liver disease. The length of hospice and palliative care for above patients was not enough to attend them. Therefore, we suggest that proper education and information should be provided to physicians, patients, and their family members for effective hospice and palliative care.
