Purpose: Acute kidney injury (AKI) is a common complication during hospitalization and is an accepted risk factor for in-hospital mortality. However, the association of severity of AKI with the long-term risk of death is not well known. This study aimed to investigate the incidence and clinical significance of AKI in patients with acute myocardial infarction (AMI). Methods: To examine the effect of the severity of AKI on 1-year risk of death following AMI, we performed an observational study of 1,224 patients admitted for AMI. We evaluated the association between AKI and all-cause mortality. Patients with maintaining hemodialysis treatment (n=7), and who died during hospitalization (n=71) were excluded. Remaining 1146 patients were divided into three groups according to the Acute Kidney Injury Network (AKIN) criteria (Stage-1, -2, and-3). The primary end point of the study was 1-year all-cause mortality after hospital discharge. The relation between the severity of AKI and 1-year mortality after AMI was analyzed. Results: AKI was developed in 222/1,146 (19.3%) patients during the hospital stay. Adjusted hazard ratio for 1-year mortality was 3.064 (95% CI 1.618 to 5.803, p=0.001), 6.112 (95% CI 2.344 to 15.935, p<0.001) and 20.030 (95% CI 5.428 to 73.912, p<0.001) in stage-1, -2, and stage-3 AKI groups compared with that of no AKI group. Conclusion: The severity of AKI is strongly related to 1-year all cause mortality in patients with AMI.

목적: 임상적으로 FENa가 일과성 신손상 (T-AKI)과 지속성 신손상 (P-AKI)을 감별하는 데 많이 사용되지만 이뇨제를 사용한 환자에서 FENa는 유효 혈류량 결핍 상태에서도 증가하게 되어 진단적 정확성이 떨어진다고 알려져 있다. 본 연구에서는 이뇨제 투여상황에서 FE(Na)와 비교하여 FE(Urea)의 진단적 유용성에 대하여 알아보고자 하였다. 방법: 107명의 급성 신손상 환자를 임상적 특성에 따라 일과성과 지속성 신손상 군으로 나누고 이를 다시 이뇨제 투여 유무에 따라 재분류하였다. ROC 곡선에 따라 계산된 cutoff value에 따라서 일과성 신손상을 정의하였고 이뇨제 투여로 인한 cutoff value의 변화에 따른 민감도와 특이도를 비교하였다. 결과: AKI가 발생한 107명의 모든 환자중 검사 이전에 경험적으로 이뇨제를 사용한 경우가 67명으로 63%를 보였고, 일과성 신손상군의 경우는 52명 중 27명으로 52%를, 지속성 신손상군의 경우는 55명 중 45명으로 73%를 보였다. ROC curve에 따라 cutoff value를 FE(Na)≤1.5 FE(Urea)≤30으로 하였을 때 T-AKI를 진단하는 데 사용된 두 값의 민감도와 특이도는 모든 환자군에서 FE(Na)가 81%, 98%를, FE(Urea) 가 94%, 82%를 보였다. 이뇨제 비투여군에서는 FE(Na)가 96 %, 100%를, FEUrea가 92%, 87%를 보였으며, 이뇨제 투여군에서는 FE(Na)가 63%, 98%를, FE(Urea)가 96%, 83%를 보였다. 결론: 이뇨제를 사용한 경우 P-AKI를 진단하는데 FE(Urea)도 FE(Na) 정도의 진단적 유용성을 가진다. Purpose: Although fractional excretion of sodium (FE(Na)) has been used to distinguish transient-acute kidney injury (T-AKI) from persistent-AKI (P-AKI), the availability of FE(Na) in the diagnosis of T-AKI is reported low in patients with diuretics use. We compared the diagnostic performance of fractional excretion of urea (FE(Urea)) with that of FE(Na) in patients with diuretics use. Methods: One hundred seven AKI patients were classified as having T-AKIor P-AKI according to the clinical context. Each group was again subdivided according to exposure to diuretics. According to the cut off value generated by receiver operating characteristic (ROC) curves, sensitivity and specificity of FE(Na) and FE(Urea) were compared with each other. Results: The numbers of patients administered with diuretics were 67 out of total 107 AKI patients (63%), 27 out of 52 (52%) of T-AKI patients, and 40 out of total (65) 55 (73%) of P-AKI patients. When the cutoff value of T-AKI was defined as FE(Na) ≤1.5 and FE(Urea) ≤30 according to the ROC curves, sensitivity and specificity of FE(Na) were 96% and 100% in non-diuretics group, and 63% and 98% in diuretics group, respectively. Sensitivity and specificity of FE(Urea) were 92% and 87% in non-diuretics group, and 96% and 83% in diuretics group, respectively. Conclusion: FE(Urea) is as good as FE(Na) at distinguishing T-AKI from P-AKI in patients administered with diuretics.

Background/Aims: Continuous renal replacement therapy (CRRT) has been widely used for treating critically ill patients with acute kidney injury (AKI). Whether CRRT is better than intermittent hemodialysis for the treatment of AKI remains controversial. We sought to identify the clinical features that can predict survival for the patients who are treated with CRRT. Methods: We analyzed the data of 125 patients who received CRRT between 2005 and 2007. We identified the demographic variables, the underlying diagnoses, the duration of CRRT, the mean arterial blood pressure (ABP) and the Simplified Acute Physiology Score (SAPS) II. The classification/staging system for acute kidney injury (AKI) was applied to all the patients, who were then divided into stage 1-3 subgroups. Results: The average age of the patients was 61.414.3 years and the mortality rate was 60% (75 of 125 patients). The survivors had a significantly higher mean ABP and a higher mean serum bicarbonate level, which were measured the day after CRRT, than the nonsurvivors (86.723.7 vs. 69.224.6 mm Hg, respectively, 21.43.5 vs. 16.45.4 mmol/L, respectively,; p<0.05 for each). The stage 3 AKI patients showed the worst parameters for the SAPS II score and the serum levels of creatinine and blood urea nitrogen. The mortality rate was higher for the stage 3 subgroup than the other groups (70.5%, p<0.05). Conclusions: The patients with AKI and who require CRRT continue to have a high mortality rate. A higher mean ABP and a higher serum bicarbonate level measured the day after CRRT may predict a more favorable prognosis. The staging system for AKI can improve the ability to predict the outcomes of CRRT patients.

Background: For treating displaced patella fractures, tension band wiring is the most widely used technique. However, implant removal surgery is often necessary to alleviate discomfort caused by fixation materials. On the contrary, fixation using nonabsorbable suture materials is anticipated to result in comparable outcomes without need for further implant removal surgery. However, there is a lack of clinical studies comparing the two fixation techniques (wire and nonabsorbable suture materials) for acute patella fractures. Methods: From 2014 to 2018, we retrospectively reviewed 60 patients who underwent open reduction with internal fixation for acute patella fracture. Thirty patients (group 1) who received surgery using tension band wiring and 30 patients (group 2) who received surgery using nonabsorbable suture materials were enrolled. The average follow-up period was more than 1 year after operation. Operation time, postoperative bone union time, range of motion (ROM) of the knee joint, postoperative clinical results, and complications were compared between the two groups. Result: Operation time, clinical bone union, and radiologic bone union were not statistically different between groups 1 and 2. At 3 months postoperatively, flexion was 120.3 ± 9.4° in group 1 and 110.5 ± 7.7° in group 2, showing statistically significant difference (p = 0.037). At 6 and 12 months postoperatively, the ROM was similar in both groups. Hospital for special surgery score at 3 months postoperatively was 78.4 ± 8.2 in group 1 and 83.7 ± 8.7 in group 2, showing statistically significant differences (p = 0.032). However, at 6 and 12 months postoperatively, there were no statistical differences. Lysholm score at 3 months postoperatively was 73.5 ± 8.1 in group 1 and 80.4 ± 8.2 in group 2, showing statistically significant difference (p = 0.016), but at 6 and 12 months postoperatively, there were no statistical differences. Conclusion: Fixation using multiple nonabsorbable suture materials can be an alternative surgical method in managing patella fractures, along with tension band wiring.

This study empirically investigates the effect of self presentation on SNS to interpersonal relation and quality of life. Especially, we performed exploratory analysis that how SNS affect to quality of life and wether the change of interpersonal relation is mediating effect to quality of life and intention to use. And we also suggest that the capability of communication would be a moderator. In the results, firstly, the using SNS has significantly positive effect on the change of interpersonal relation. And it as mediation variable can positive impact on the relationship between the using SNS, quality of life, and Intention to use. In the moderating analysis, SNS users who responded higher communication capability have significantly more higher effect on the change of interpersonal relation and quality of life. Secondly, the change of interpersonal relation after use of SNS as a mediation variable serves to enhance the relationship between the use of SNS and the quality of life in the positive direction.

Purpose: To report a case of bilateral Coats' disease. Case summary: A 19-month-old boy presented with esodeviation of his eyes, which started 5 months prior. A fundus exam showed total bullous exudative retinal detachment with retinal vascular telangiectasia in the right eye and localized exudative retinal detachment with vascular telangiectasia at the inferior periphery in the right eye. Fluorescein angiogram of the left eye showed retinal telangiectatic vessels, avascular area and fluorescein leakeage from telangiectatic vessels. The patient received external drainage of subretinal fluid and intravitreal air injection of the right eye and Argon LASER photocoagulation and cryotheraphy of the left eye. A cytologic exam of the subretinal fluid drained from the right eye showed no malignant cells. Forty-four months after the operation, his best corrected visual acuity was no light perception in the right eye and 0.4 in the left eye. Both fundi were flat and stable. No complications, such as glaucoma, recurred retinal detachment, or pain, occurred. Conclusions: Coats' disease rarely occurs bilaterally and can be involved asymmetrically. The disease presents more severely when bilateral and can progress after long-term observation. Proper treatment and long-term follow-up of both eyes are necessary to prevent visual loss and preserve eyes. J Korean Ophthalmol Soc 2011;52(1):112-116
