AbstractAbstract PDF
An institutional review board (IRB) should independently safeguard the right, safety, and well-being of all clinical trial subjects. It should consist of members who are qualified and experienced to review and evaluate the science, medical aspects, and ethics of the proposed trial. They have to pursue continuing efforts to improve the standards of review. The levels of review include the full board review, expedited review, continuing review, or exempt from review, while the levels of decision-making include approval, conditional approval, deferred approval, and disapproval. Investigators must follow the approved protocols and regulations honestly, and it is the IRB's mission to audit clinical trial sites as well.

AbstractAbstract PDF
Collapsing glomerulopathy (CG) has become an important cause of end-stage renal disease (ESRD). First delineated from other proteinuric glomerular lesions in the 1980s, CG is now recognized as a common, distinct pattern of proliferative parenchymal injury that portends a rapid loss of renal function and poor responses to empirical therapy. The first cases in the literature trace back to human-immunodeficiency-virus (HIV)-negative patients who underwent biopsy in 1979. A 45-year-old male patient complained of hematuria and proteinuria eight years ago. He showed an abrupt serum creatinine increase from 1.75 to 2.65mg/dL in the last preceding months. Afterwards, his serum creatinine progressively increased up to 6.82mg/dL. Moreover, his 24 h urine protein level was determined to have reached 6,171 mg/day, as opposed to 670 mg/day a year earlier. Consequently, renal biopsy was performed, and its result showed collapsing glomerulopathy, compatible with the diagnosis. He has undergone continuous ambulatory peritoneal dialysis as renal replacement therapy. Thus, it is reported herein that a patient clinically diagnosed with chronic kidney disease eight years ago showed a sudden renal-function decrease and was clinicopathologically diagnosed with collapsing glomerulopathy based on the results of his renal biopsy.

AbstractAbstract PDF
Henoch-Schonlein purpura (HSP) is a leukocytoclastic vasculitis of small vessels with deposition of IgA, commonly resulting in skin, joint, gastrointestinal, and kidney involvement. HSP is an uncommon disorder in adults and accounts for 0.6% to 2% of adult nephropathy. We report a case of HSP with acute renal failure successfully treated with corticosteroid. In this case, the patient presented with vasculitic purpuric rash on lower extremity, arthralgia in the wrist, abdominal pain, hematochezia, oliguria and azotemia. Abdominal CT showed wall thickening of the small and large bowels. Skin biopsy revealed leukocytoclastic vasculitis. Percutaneous renal biopsy showed no crescent formation, but mesangial IgA and C3 deposits were observed by immunofluorescence. The patient was treated with corticosteroid (1mg/kg per day) and hemodialysis. After treatment, renal function improved and purpuric lesion, arthralgia and abdominal pain disappeared. Thus, when adults present with purpuric rash and rapidly progressive glomerulonephritis (RPGN), HSP should be a diagnostic consideration.

AbstractAbstract PDF
We report the result of a high-dose intravenous immunoglobulin therapy in a Henoch-Sch?nlein purpura patient with severe abdominal pain and nephrotic syndrom who did not respond to methylprednisolone pulse therapy. Kidney bbiopsy showed diffuse mesangial cell proliferative glomerulonephritis with fibrocellular crescent formation in approximately 50% of glomeruli. Mesangium of all glomeruli were strong positive for IgA and C3 antibodies. High-dose intravenous immunoglobulin treatment was introduced and dramatic improvement of gastrointestinal symptom and proteinuria as well as hematuria was noted. Immunoglobulin administration should be considered in Henoch-Schnlein purpura patients with sterois-resistant intractable dastrointestinal manifestation and renal involvenment.

BACKGROUND
The number of glomerulus has been considered one of the etiologic factors especially for focal segmental glomerulosclerosis. However. glomeruli are too many to calculate them correctly. Although the fractionator method has became convinced, in which they used selected sections, not whole kidney sections, with same intervals, it is also very hard to get good results. Because it is still very time-consuming and laborous work which leads to make big observers' biases. METHODS AND MATERIALS: We designed the index for glomerular number to estimate the tendency of increase or decrease of the number of it in different kidneys and which was evaluated by other conventional methods including fractionator method. Index was based upon the theory by 1\yengaard: "the number of glomerulus correlates with the weight of kidney, which is positively correlated with body weight". Calculating formula is the number of glomeruli/surface areas of cortices which contain calculated glomeruli multiplies by kidney weight/body weight. RESULTS: We applied this index to kidneys of FGS/Kist mouse and those of RFM/ Nga mouse. The former is spontaneous glomerulosclerosis modelwith heavy protein uria and renal failure and the latter is the mother side of FGS/Kist mouse but has no glomerular disease or protein uria. The number of glomerulus of FGS/Kist mouse was decreased by 30% to those of RFM/Nga mouse. CONCLUSION: This index was useful and reliable for estimating the relative glomerular number between two groups.

AbstractAbstract PDF
A rare case of telangiectatic osteosarcoma of the sphenoid bone was reported. The patient was a 27-year-old male and had suffered from left eye protrusion and diplopia for three months. Radiologically, a lobulated osteolytic lesion was located between sphenoid and left temporal bone. Pathologically, the tumor had multiloculated blood filled cystic vascular spaces and osteoid formation by malignant spindle osteoblast cells. The differential diagnosis of this rare entity from aneurysmal bone cyst was important radiologically and pathologically. This case is the second case of telangietatic osteosarcoma of the sphenoid bone followed by a case of Whitehead RE and Melhem ER in 1998.
