1/460. prognosis of acute poststreptococcal glomerulonephritis in childhood: prospective study and review of the literature.Serial, clinical, clinicopathologic and histologic studies performed simultaneously following onset of PS-AGN in children for a period of up to 144 months revealed no evidence of progression to chronic glomerulonephritis. Although acute morphologic changes were more severe in renal tissue obtained from patients with AGN following streptococcal upper respiratory infection than following pyoderma, the acute manifestations in both groups subsided 6 to 12 weeks after onset. Cumulative morphologic healing occurred in 20% of patients at 24 months, in 43% at 48 months after onset of PS-AGN; 1 patient who was unhealed at 49 months was lost to follow-up. In 2 patients (6%), acute histologic exacerbations without clinical signs occurred within 24 months after onset. Subsequent healing was documented histologically. Addis counts remained abnormal in a high percentage of patients throughout the 12 years of observation and did not correlate with the histologic findings of renal biopsy tissue. The occasional demonstration of renal vascular disease and/or hypertension may merely reflect the early development of spontaneous essential hypertension although the possibility of a relationship to the previous attack of PS-AGN is intriguing. This question cannot be answered at this time. Renal biopsy studies are more dependable than Addis counts in assessing the course of PS-AGN. The significance of persistence of immunofluorescent and/or electron microscopic changes (subepithelial dense deposits) many years after onset in 58% of 12 patients studied, at a time when a majority of patients (84%) revealed healing by light microscopy, remains to be assessed.- - - - - - - - - - ranking = 1keywords = nephritis (Clic here for more details about this article) |
2/460. Recovery of both acute massive pulmonary hemorrhage and acute renal failure in a systemic lupus erythematosus patient with lupus anticoagulant by the combined therapy of plasmapheresis plus cyclophosphamide.Acute massive pulmonary hemorrhage (AMPH) is a rare and highly fatal complication in systemic lupus erythematosus (SLE). We report here survival in a case of AMPH in a SLE patient with both rapidly progressive glomerulonephritis and lupus anticoagulant. The AMPH occurred while the nephritis was refractory to 2 courses of pulse methylprednisolone therapy. After combined therapy with plasmapheresis plus cyclophosphamide, circulating immune complex levels declined, AMPH recovered, and serum creatinine levels returned to normal. In conclusion, the combined therapy of plasmapheresis plus cyclophosphamide should be considered for treating AMPH especially in those SLE patients with rapidly progressive glomerulonephritis.- - - - - - - - - - ranking = 0.6keywords = nephritis (Clic here for more details about this article) |
3/460. Computed tomography and pathologic findings in fulminant forms of idiopathic interstitial pneumonia.This study describes the computed tomography features of various fulminant forms of idiopathic interstitial pneumonia and to clarify the usefulness of computed tomography in such patients. Computed tomography scans in 19 patients with fulminant forms of idiopathic interstitial pneumonia were reviewed. This study included patients with acute interstitial pneumonia (n = 7), an accelerated form of idiopathic pulmonary fibrosis (n = 2), and an acute exacerbation of idiopathic pulmonary fibrosis (n = 10). Pathologic confirmation of the diagnosis was obtained in all patients. Follow-up computed tomography scans were available for eight patients, and postmortem computed tomography scans were available for three patients. All patients had progressive ground-glass attenuation, consolidation, or both. In patients with an acute exacerbation of idiopathic pulmonary fibrosis, subpleural honeycombing was also seen. Follow-up computed tomography showed a change from ground-glass attenuation to consolidation with distortion. Architectural distortion, traction bronchiectasis, and ground-glass opacity were the prominent features in the initial computed tomography scans obtained more than 7 days after the onset of symptoms, and cystic lesions were seen in follow-up computed tomography obtained more than 1 month after the onset. High-resolution computed tomography was more sensitive than the plain radiographs in the early detection of these entities. Computed tomography examination at the onset of the acute symptoms is useful in classifying these fulminant forms of idiopathic interstitial pneumonia.- - - - - - - - - - ranking = 0.088240175102574keywords = interstitial (Clic here for more details about this article) |
4/460. Tubulointerstitial nephritis associated with minimal self reexposure to rifampin.We report the case of a 27-year-old Asian man who self-medicated with two capsules of rifampin 1 year after completing a continuous course of chemotherapy for tuberculosis that included that drug. He developed flank pain and edema and presented with uremia requiring dialysis; despite this, he had a serum potassium of only 3.5 mEq/L. Renal biopsy showed interstitial infiltrate with inflammation of the tubules. Renal function began to improve after a 3-week course of prednisone. This case is remarkable for the severity of the renal failure despite such a minimal self-exposure.- - - - - - - - - - ranking = 1.6795516337164keywords = interstitial nephritis, nephritis, interstitial (Clic here for more details about this article) |
5/460. A case of acute diffuse interstitial nephritis due to sulpyrine.Sulpyrine is commonly used in japan.

6/460. Acute respiratory distress syndrome in a welder exposed to metal fumes.A 43-year-old man began having malaise, chills, and fever 12 hours after cutting a galvanized steel grating with an acetylene torch at work. Over the next 72 hours, his symptoms persisted and became worse with progressive shortness of breath. He was admitted to the hospital and begun on antibiotics and steroids. The next day his condition had deteriorated to the point that he had to be intubated. Chest x-ray film and computed tomography showed patchy and interstitial infiltration bilaterally, consistent with acute respiratory distress syndrome. Open lung biopsy showed focal mild interstitial pneumonia. Multiple laboratory studies were negative for an infectious or an immune process. The patient remained on mechanical ventilation for 10 days and was discharged from the hospital 2 days after extubation. He continued to improve, with minimal symptoms and a return to normal activity levels several months after the incident with no continued treatment. Re-creation of his exposure was done under controlled circumstances, with air sampling revealing elevated air levels for cadmium and zinc and borderline levels of arsenic, manganese, lead, and iron.- - - - - - - - - - ranking = 0.022060043775643keywords = interstitial (Clic here for more details about this article) |
7/460. Acute eosinophilic interstitial nephritis and uveitis (TINU syndrome) associated with granulomatous hepatitis.A 23-year-old male presented with renal failure, cholestatic liver enzyme elevation and uveitis. Percutaneous renal biopsy revealed marked eosinophilic infiltration of the renal interstitium, which made the diagnosis of TINU syndrome (Tubulo-Interstitial Nephritis and uveitis). Percutaneous liver biopsy showed granulomatous hepatitis, which was not described as a part of TINU syndrome. The diagnostic dilemma and the literature are discussed.- - - - - - - - - - ranking = 1.6685216118286keywords = interstitial nephritis, nephritis, interstitial (Clic here for more details about this article) |
8/460. Acute interstitial nephritis following amoxicillin overdose.Antibiotics are commonly prescribed medications for pediatric infections. Acute interstitial nephritis has been reported with B-lactam antibiotics. We report the case of a 4-year-old boy who ingested 240 mg/kg of amoxicillin and developed acute oliguric renal failure with hematuria and crystalluria. The patient was hospitalized for serial renal function and electrolyte evaluation. Although he developed hyperkalemia, full recovery was obtained with conservative management. This case emphasizes that medications considered to be non-toxic even with overdose can have serious adverse effects which may require therapeutic intervention.- - - - - - - - - - ranking = 2.0856520147857keywords = interstitial nephritis, nephritis, interstitial (Clic here for more details about this article) |
9/460. peliosis hepatis with initial presentation as acute hepatic failure and intraperitoneal hemorrhage in children.peliosis hepatis, a condition characterized by the presence of blood-filled lacunar spaces in the liver, usually has a chronic presentation pattern and is mainly reported in adult patients in association with chronic wasting disorders and after administration of various drugs. The present report concerns two previously healthy young children in whom peliosis hepatis initially presented as acute hepatic failure and who had escherichia coli pyelonephritis. Both patients had active intraperitoneal hemorrhage from the peliotic liver lesions, and liver ultrasonography showed multiple hypoechoic areas of different sizes, which in this context should suggest the diagnosis. One child died from hypovolemic shock and the other recovered. This study indicates that acute peliosis hepatis can be a serious life-threatening disease in children.- - - - - - - - - - ranking = 0.2keywords = nephritis (Clic here for more details about this article) |
10/460. nephrotic syndrome and acute interstitial nephritis associated with the use of diclofenac.Commonly reported renal complications of non-steroidal anti-inflammatory drugs (NSAID) include acute renal failure and/or acute interstitial nephritis; in rare cases a nephrotic syndrome was also observed. In most cases this was due to the development of secondary membranous nephropathy. Following withdrawal of the drug the nephrotic syndrome usually resolved rapidly. We report a 65-year-old woman who developed a nephrotic syndrome and acute renal failure during 6 months of treatment with the NSAID diclofenac. Renal biopsy revealed both, membranous nephropathy and interstitial nephritis. After discontinuation of diclofenac and treatment with prednisone 1 mg/kg/day, furosemide 400 mg/day and simvastatin at a dose of 20 mg/day, creatinine clearance gradually increased and after 5 months of treatment complete remission of the nephrotic syndrome was observed.- - - - - - - - - - ranking = 2.5027824177429keywords = interstitial nephritis, nephritis, interstitial (Clic here for more details about this article) |
