Purpose: The purpose of this study is to investigate correlations in vital sign changes, the severity of pain, signs of complications, and the duration of sandbag management in order to suggest a standardized practice related to sandbag management in children with Nephrotic Syndrome(NS). Method: From October 2000 to May 2001, seventy children with NS who underwent kidney biopsy were interviewed at one hospital in Seoul Korea, and participated in this study. Result: 1) The average sandbag applying time after kidney biopsy was 18.1 hours. 2) Systolic blood pressure and respiration increased until 15 minutes after kidney biopsy, after then, they decreased signifi- cantly (systolic BP, p= .006; respiration, p= .029). However, no significant changes were noted in diastolic blood pressure and pulse. 3) Pain was reported minimal for 1 hour after kidney biopsy. The severity of pain increased until 12 hours after the procedure, then, decreased significantly(p= .0001). 4) Reported complications were hematuria (74.7％) and abnormal sonogram (32.9％). No apparent bleeding on the biopsy region was reported in any children. Conclusion: From these findings, it is possible to change the protocols of the duration of absolute bed rest time and sandbag application management shortly after kidney biopsy. But it is needed to study the fit protocols for kidney biopsy. Several implications in nursing practice are suggested. 1) Replicated studies for more participants are needed. 2) Further research on the effect of sandbag application after kidney biopsy is required. 3) The best duration of sandbag application management after kidney biopsy need to be investigated.

Proteinuria is an important risk factor for renal and cardiovascular disease. It is associated with a risk for glomerulonephritis, chronic kidney disease, and end-stage renal disease. Therefore, if persistent proteinuria is detected, kidney biopsy is considered to diagnose and treat the underlying disease. Recently, variants in the cubilin (CUBN) gene, which is associated with albuminuria, have been reported. This gene encodes cubilin, a membrane glycoprotein receptor expressed in the renal proximal tubules. Cubilin is a component of the megalin and cubilin-amnionless complex that mediates albumin reabsorption into the proximal tubules through endocytosis. A defect in cubilin leads to a reduction in albumin reuptake, resulting in albumin-dominant proteinuria. Although numerous controversies exist, several reports suggest that cubilin defects lead to proteinuria with a high portion of albuminuria but may not impair renal filtration function. If albuminuria due to reduced cubilin function is confirmed as a benign condition, we can consider using genetic studies to detect CUBN mutations in patients with proteinuria and they may not require any treatment or kidney biopsy. Here, we review recent papers on CUBN mutations and discuss the prognosis and management of individuals with this mutation.

Purpose : To analyse the results of the renal biopsies and the clinical diagnoses of patients who had undergone percutaneous kidney biopsies in the department of pediatrics at Kyunghee University Hospital for 22 years from 1984 to 2005. Methods : We retrospectively reviewed the medical records of 1559 patients and analyzed the chief complaints that led to a renal biopsy, age, sex, histopathologic findings and diagnosis. Routine kidney biopsies were performed by automated gun biopsy guided by real time ultrasonography. The diagnoses were made based on the specimen's light microscopy, immunofluorescence microscopy and electron microscopy findings and clinical symptoms and signs. Results : The mean age of the patients was 10 years with the male to female ratio being 1.3:1. The chief complaints that led to a renal biopsy included hematuria only(753 cases, 48.3%), proteinuria only(125 cases, 8.0%) and hematuria combined with proteinuria(537 cases, 34.4%). The most frequent histopathological finding was primary glomerular disease(75.4%) which included IgA nephropathy(30.1%) and mesangial proliferative glomerulonephritis(27.6 %). Systemic disease comprised 11.4% which included Henoch-$Sch\ddot{o}nlein$ nephritis(10.5%) and lupus nephritis(0.8%). Alport syndrome was found in 1.1% of cases which was attributed to hereditary causes. 628 children(40.3%) visited the clinic due to abnormal school urine screening abnormalities and among these, 237 children had mesangial proliferative glomerulonephritis and 234 children who had IgA nephropathy were managed thereafter. Conclusion : IgA nephropathy and mesangial proliferative glomerulonephritis were the two major forms of primary glomerulonephritis found in Korean children who had kidney biopsies from 1984 to 2005.

Purpose: The purpose of this study was to examine the effect of absolute bed rest(ABR) on occurrence of bleeding, discomfort and back pain after kidney biopsy. Method: This study was the nonequivalent control group posttest design. The experimental group was allowed to stay in beds for 18 hour-bed rest(BR) after 6 hour-ABR while the control group was allowed to stay ABR for 24 hours. Results: No bleeding sign was showed for all the patients. Discomfort of voiding, eating, ABR in the control group appeared at a higher level. Three subjects in the control group needed nelaton catheterization, whereas no catheterization was required in the experimental group. There was no significant difference in back pain. However, the control group used more pain killer with significant difference. From these results. Conclusion: There was no significant correlation between ABR time and bleeding. On the other hand, the discomfort of the experimental group appeared at a lower level by reducing ABR time. Therefore, Reduction of ABR time after kidney biopsy would be more efficient way for patients.

Glomerulocystic kidney disease(GCKD) is a rare form of renal cystic disease defined histopathologically by containing dilated Bowman's space with variable atrophy of glomerular tufts, which may occur as sporadically or as familial cases and can be presented as a major component of heritable syndromes. It has not been recognized in Korean children but only one report of adult case has been reported having GCKD. We experienced a case of GCKD in a 10-year-10-month-old boy, who was admitted for hypertension. Abdominal ultrasonography and computed tomography revealed clustered numerous small cysts in left kidney and renal biopsy findings was consistent with the GCKD showing cystic dilatation of Bowman's space with intact glomerular structure.

Nutcracker syndrome (NCS) is a disease caused by compression of the left renal vein between the superior mesenteric artery and the abdominal aorta. Immunoglobulin A (IgA) nephropathy (IgAN) is characterized by the predominance of IgA deposits in the glomerular mesangial area. Hematuria and proteinuria can be present in both diseases, and some patients can be concurrently diagnosed with NCS and IgAN; however, a causal relationship between the two diseases has not yet been clarified. Here, we report two pediatric cases of NCS combined with IgAN. The first patient presenting with microscopic hematuria and proteinuria was diagnosed with NCS at the initial visit, and the second patient was later diagnosed with NCS when proteinuria worsened. Both patients were diagnosed with IgAN based on kidney biopsy findings and treated with angiotensin-converting enzyme inhibitors and immunosuppressants. A high index of suspicion and timely imaging or biopsy are essential for the proper management of NCS combined with glomerulopathy.

Cerebral toxoplasmosis is often life-threatening in an immunocompromised patient due to delayed diagnosis and treatment. Several differential diagnoses could be possible only with preoperative brain images of cerebral toxoplasmosis which show multiple rim-enhancing lesions. Due to the rarity of cerebral toxoplasmosis cases in Korea, the diagnosis and treatment are often delayed. This paper concerns a male patient whose cerebral toxoplasmosis was activated 21 years post kidney transplantation. Brain open biopsy was decided to make an exact diagnosis. Cerebral toxoplasmosis was confirmed by immunohistochemistry and PCR analyses of the tissue samples. Although cerebral toxoplasmosis was under control with medication, the patient did not recover clinically and died due to sepsis and recurrent gastrointestinal bleeding.
