We evaluated forty cases of traumatic diaphragmatic injuries that we have experienced from Jan. 1972 to Dec. 1987. 28 patients were male and 12 were female[M:F=2.3:1]. The age distribution was ranged from 4 to 71 years with mean age of 26. The diaphragmatic injuries were due to blunt trauma in 27 cases[traffic accident 22, fall down 3, others 2] and penetrating trauma in 13 cases[stab wound 11, gun shot 1, other 1]. In the blunt injury,14 cases of 17 were diagnosed and treated within 24 hours in the left diaphragmatic injury but only 3 cases of 7 cases in the right diaphragmatic injury were diagnosed and treated within 24 hours. All cases except one in penetrating injury were diagnosed and treated within 12 hours. In the blunt injury, the rupture site was located in the left in \ulcorner7 cases and in the right in 7 cases. In the penetrating injury, the rupture site was located in the left in 11 cases and in the right in 2 cases. The repair of 37 cases were performed with thoracic approach in 20 cases, thoracoabdominal approach in 12 cases and abdominal approach in 5 cases. Over all mortality was 17.5%[7/40] and postoperative mortality was 11%[4/37]. The causes of death were hypovolemic shock[3], combined head injury[2], acute renal failure[1] and septic shock with ARDS[1].

Background: Acute kidney injury is an important issue in chemotherapy receiving patients an neutrophil gelatinase-associated lipocalin has been proposed as a novel marker. We here aimed to assess the role of urinary levels for assessment after platin exposure. Materials and Methods: Patients who had treated with cisplatin or carboplatin or oxaliplatin containg regimens were included in this study. Baseline and postchemotherapy serum urea, creatinine, urine neutrophil gelatinase-associated lipocalin and urine creatinine levels were determined. To avoid the effects of hydration during chemotherapy infusion the urinary neutrophil gelatinase-associated lipocalin/urine creatinine ratio was used to determine acute kidney injury. Results: Of a total of 42 patients receiving platin compounds,14 (33.3%) received cisplatin containing regimens, 14 (33.3%) received carboplatin and 14 (33.3%) oxaliplatin. The median age was 60 (37-76) years. Nineteen of the patients (45.2%) had lung cancer, 12 (28.6%) colorectal cancer and 11 (26.2%) others. The median pre and post chemotherapy urine neutrophil gelatinase-associated lipocalin/urine creatinin ratio was 15.6 ng/mg and 35.8 ng/mg (p=0.041) in the cisplatin group, 32.5 ng/mg and 86.3 ng/mg (p=0.004) in the carboplatin group and 40.9 ng/mg and 62.3 ng/mg (p=0.243) in the oxaliplatin group. Conclusions: Nephrotoxicity is a serious side effect of chemotherapeutic agentslike cisplatin and carbopaltin, but only to a lower extent oxaliplatin. All platin compounds must be used carefully and urine neutrophil gelatinase-associated lipocalin measurement seems to be promising in detecting acute kidney injury earlier than with creatinine.

Background: Nephrotic syndrome (NS) is the most common glomerulopathy in children. Acute kidney injury (AKI) is a common complication of NS, caused by severe intravascular volume depletion, acute tubular necrosis, interstitial nephritis, or progression of NS. However, the incidence and risk factors of childhood-onset NS in Korea are unclear. Therefore, we studied the incidence, causes, and risk factors of AKI in hospitalized Korean patients with childhood-onset NS. Methods: We conducted a retrospective review of patients with childhood-onset NS who were admitted to our center from January 2015 to July 2017. Patients with decreased renal function or hereditary/secondary NS, as well as those admitted for management of other conditions unrelated to NS, were excluded. Results: During the study period, 65 patients with idiopathic, childhood-onset NS were hospitalized 90 times for management of NS or its complications. Of these 90 cases, 29 met the Kidney Disease Improving Global Outcomes criteria for AKI (32.2%). They developed AKI in association with infection (n = 12), NS aggravation (n = 11), dehydration (n = 3), and intravenous methylprednisolone administration (n = 3). Age ${\geq}9$ years at admission and combined use of cyclosporine and renin-angiotensin system inhibitors were risk factors for AKI. Conclusion: AKI occurred in one-third of the total hospitalizations related to childhood-onset NS, owing to infection, aggravation of NS, dehydration, and possibly high-dose methylprednisolone treatment. Age at admission and use of nephrotoxic agents were associated with AKI. As the AKI incidence is high, AKI should be considered during management of high-risk patients.

Plastibell is one of the three most common devices used for neonatal circumcision in the United States, with a complication rate as low as 1.8%. The Plastibell circumcision device is commonly used under local anesthesia for religious circumcision in male neonates, because of cosmetic reasons and ease of use. Occasionally, instead of falling off, the device may get buried under the skin along the shaft of the penis, thereby obstructing the normal flow of urine. Furthermore, the foreskin of neonates is highly vascularized, and hence, hemorrhage and infection are possible when the skin is cut. Necrosis of penile skin, followed by urethral obstruction and renal failure, is a serious surgical mishap requiring immediate corrective surgery and medical attention. We report a case of fulminant urosepsis, acute renal failure, and pyelonephritis in a 4-day-old male neonate secondary to impaction of a Plastibell circumcision device. Immediate medical management was initiated with fluid resuscitation and mechanical ventilation; thereby correcting life threatening complications. Pediatricians and Emergency Department physicians should be cognizant of the complications from Plastibell circumcision device in order to institute appropriate and timely management in neonates.

Milk-alkali syndrome (MAS), a triad of hypercalcemia, metabolic alkalosis, and renal failure, is associated with ingestion of large amounts of calcium and absorbable alkali. MAS is the third most common cause of hypercalcemia in hospital, after primary hyperparathyroidism and malignant neoplasm. MAS is not often reported in the Korean literature. We describe MAS secondary to intake of calcium citrate for the treatment of osteoporosis with thoracic spine compression fracture. A 70-year-old man presented to our hospital with a 1-week history of general weakness and lethargy. He was found with acute kidney injury (serum creatinine, 4.6 mg/dL), hypercalcemia (total calcium, 14.8 mg/dL), and alkalosis. Laboratory evaluation excluded both hyperparathyroidism and malignancy. Mental status and serum calcium level was normalized within a week after proper hydration and intravenous administration of furosemide. However, he developed aspiration pneumonia, pseudomembranous colitis, and sepsis with multi-organ failure. Despite intensive treatment including inotropics, mechanical ventilation, and renal replacement therapy, he expired with no signs of renal recovery on the 28th hospital day.

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.

허혈/재관류 손상은 장기이식 분야에서 해결해야 할 주요 문제점으로 알려져 있다. 본 연구에서는 대퇴 동,정맥 부위에서 기존의 혈관 문합법 대신 맥관 connector를 이용하여 간단하면서 효과적인 체외 재관류 모델을 개발하였기에 소개하고자 한다. 개발된 모델이 허혈/재관류 손상연구에 효과적인지 알아보기 위해 혈액 동력학적 평가와 신장의 재관류 후 손상 양상을 분석하였다. 기존의 재관류 모델에서 사용되는 문합 부위인 복강 대동맥의 혈압과 본 연구에서 재관류 부위로 활용된 대퇴동맥의 혈압은 유의적 차이가 없었다. 허혈 손상 후 재관류 효과를 알아보기 위해 미니돼지에서 적출한 신장을 HTK 용액에 24, 48시간 동안 각각 저온보관 후 대퇴부에 이식하여 재관류 한 결과, 신장의 재관류까지 수술시간은 평균 $7.0{\pm}1.1$분 소요되었으며, 3시간 재관류 후 재관류 손상 정도는 저온보관시간에 따라 증가되는 것이 확인되었다. 이는 개발된 모델이 맥관 문합 없이 간단한 관류방법이면서도 기존의 복잡한 수술에 의한 재관류 방법과 유사한 손상 모델을 만들 수 있는 효과적인 허혈/재관류 동물모델이라는 것을 의미한다. 따라서 본 연구에서 개발한 신장 재관류 모델은 초기 허혈/재관류 손상 연구와 장기이식에서 이식면역연구에 효과적인 모델이라 사료된다.

Compartment syndrome has a wide spectrum from muscle pain to a life- threatening condition, such as acute renal failure and disseminated intravascular coagulation (DIC). Intracerebral hemorrhage (ICH) due to compartment syndrome has not been reported. We report a patient who presented with ICH leading to death. A 25-year-old female with no significant past history developed extensive compartment syndrome followed by rhabdomyolysis, acute renal failure, DIC, and ICH. Although the patient underwent a fasciotomy and hemodialysis and received aggressive resuscitation with massive transfusions of blood and intravenous fluids, she died. This case stresses the importance of early diagnosis and prompt treatment of compartment syndrome to prevent devastating complications.

BACKGROUND/OBJECTIVES: Hyperuricemic nephropathy is a common cause of acute kidney injury. Resveratrol can ameliorate kidney injury, but the explicit mechanism remains unclear. We investigated the effects of resveratrol on the inflammatory response and renal injury in hyperuricemic rats. MATERIALS/METHODS: A rat model of hyperuricemic nephropathy was established by the oral administration of a mixture of adenine and potassium oxinate. Biochemical analysis and hematoxylin and eosin staining were performed to assess the rat kidney function. Enzyme-linked immunosorbent assays were performed to evaluate the immune and oxidative responses. RESULTS: The expression levels of urine albumin and β2-microglobulin were significantly decreased after resveratrol treatment. In addition, the levels of serum creatinine and uric acid were significantly decreased in the resveratrol groups, compared with the control group. The levels of proinflammatory factors, such as interleukin-1β and tumor necrosis factor-α, in kidney tissue and serum were also increased in the hyperuricemic rats, and resveratrol treatment inhibited their expression. Moreover, the total antioxidant capacity in kidney tissue as well as the superoxide dismutase and xanthine oxidase levels in serum were all decreased by resveratrol treatment. CONCLUSIONS: Resveratrol may protect against hyperuricemic nephropathy through regulating the inflammatory response.
