Spontaneous rupture of the kidney. W?nderlich syndrome, is a rare event but potentially life-threatening condition. The most comman causes are clear cell carcinoma, benign angiomyolipoma and vascular disease. Among this event, acute pyelonephritis is a very unusual cause. A 67-year-old diabetic woman was admitted with high fever and left flank pain due to acute pyelonephritis. She had uterine prolapse for 10 years with both renal hydronephrosis before this event. Abdominal ultrasonography and CT scan showed fluid collection around left kidney with a rupture of renal parenchyme at lower pole. The renal angiography showed displaced capsular artery due to subcapsular hematoma and decreased blood flow at lower pole. The percutaneous needle aspiration revealed blood collection around left kidney, which confirmed spontaneous rupture of the kidney. We report this case with a review of the relevant literature.

Baclofen, a derivative of the inhibitory neurotransmitter gamma-aminobutyric acid (GABA), is used for the treatment of muscle spasm, intractable hiccups and multiple sclerosis. It is mostly excreted by glomerular filtration with a clearance that is proportional to creatinine clearance. Early hemodialysis is a treatment of the choice for baclofen-induced neurologic complication in renal failure patients. We experienced a 57-year-old hemodialysis patient with right arm muscle spasm who developed baclofen-associated encephalopathy by a single dose of oral baclofen (10 mg). He admitted to the hospital with the symptom of stuporous mental status with no specific focal neurologic signs. Brain CT imaging and blood biochemistry showed no specific abnormality. EEG revealed the typical metabolic encephalopathy findings, such as triphasic wave and frontal lobe syndrome with delta wave. After daily hemodialysis for 3 days, there was a complete recovery of an altered mentality. After one month later, the follow-up EEG showed normal finding with the resolution of abnormal waves. We report this case with a review of relevant literature. Baclofen should be used carefully, and rather recommended not to be administered in patients with renal failure.

목적: 본 연구에서는 실험적 당뇨 백서에서 p38 MAPK 억제재가 단백뇨 발생 및 세극막 관련 단백의 발현 변화에 미치는 영향을 알아보고자 하였다. 방법: Sprague-Dawley 백서 32마리를 대상으로, 16마리는 streptozotocin (65 mg/kg)으로 당뇨를 유발시켰으며 (DM군), 16마리는 위약을 투여하였다 (C군). 각 군에서 8마리는 p38 MAPK 억제제인 FR167653을 5 mg/kg의 용량으로 6주간 매일 근주하였다 (C+FR,DM+FR). 당뇨 유발 6주 후 24시간 소변을 수집한 다음 희생시켜 신장을 적출한 후 사구체를 분리하였다. 24시간 뇨알부민 배설량은 ELISA로 측정하였으며, 사구체 내 nephrin, P-cadherin, 그리고 ZO-1의 mRNA와 단백 발현은 각각 real-time PCR과 Western blot으로 분석하였다. 결과: 당뇨 유발 6주 후 24시간 뇨알부민 배설량은 C군 (0.29±0.04 mg/day)파 C+FR군 (0.32±0.04 mg/day)에 비하여 DM군 (1.09±0.17 mg/day, p<0.05)에서 유의하게 증가되었으며, 이러한 증가는 FR167653 투여로 의미있게 억제되었다 (0.38±0.05 mg/day, p<0.05). 세극막 관련 단백 중 nephrin mRNA 및 단백 발현은 DM군에서 C군에 비하여 각각 1.9배, 1.6배 증가되었으며, 이러한 증가는 FR167653 투여로 각각 74%, 89% 억제되었다 (p<0.05). 반면에, FR167653은 DM군에서 발현이 감소된 P-cadherin과 발현이 증가된 ZO-1에 의의있는 영향을 미치지 않았다. 결론: 이상의 결과로, FR167653은 당뇨 백서에서 p38 MAPK 활성화를 효과적으로 억제하였고, 뇨알부민 배설을 유의하게 감소시켰으며, 이러한 효과는 nephrin의 발현 변화의 호전과 관련이 있을 것으로 생각된다. Purpose: This study was undertaken to investigate the effect of a p38 mitogen-activated protein kinase (p38 MAPK) inhibitor, FR167653, on urinary albumin excretion and on the expression of slit diaphragm-associated proteins in diabetic rats. Methods: Thirty-two Sprague-Dawley rats were injected with diluent [control (C), N=16] or streptozotocin intraperitoneally (DM, N=16). Eight rats from each group were treated with 5 mg/kg/day FR167653 (C+FR, DM+FR) for 6 weeks. At the time of sacrifice, 24-hour urinary albumin excretion was determined by ELISA. Glomerular nephrin, P-cadherin, and ZO-1 mRNA and protein expression were determined by real-time PCR and Western blot, respectively, with sieved glomeruli. Results: Urinary albumin excretion was significantly higher in DM compared to C rats, and this increase in albuminuria was significantly inhibited by the administration of FR167653 in DM rats. Glomerular phospho-p38 MAPK protein expression was significantly increased in DM rats compared to C rats, and FR167653 treatment significantly attenuated the increase in phospho-p38 MAPK expression in DM glomeruli. Nephrin mRNA and protein expression were higher in 6-week DM compared to C glomeruli, and these increases were significantly abrogated with FR167653 treatment in DM rats. In contrast, FR167653 had no effects on the decrease in P-cadherin expression and the increase in ZO-1 expression observed in DM glomeruli.
