Case Reports
A fulminant case of renal vein thrombosis in a patient with autoimmune disorder and membranous nephropathy.
A previously healthy middle-aged woman noted a rapid onset of flank pain with gross hematuria. Enhanced CT scan showed thrombosis of the inferior vena cava and right renal vein. Laboratory findings revealed nephrotic proteinuria, Sjogren's syndrome (SjS), and Graves' disease (GD). ⋯ Renal specimens showed venous infarction with diffuse hemorrhagic and severe congestive renal necrosis, and membranous nephropathy (MN). The present case was diagnosed as acute renal necrosis due to catastrophic thrombosis in a patient with SjS, GD, and MN. It was thought that sudden development of thrombosis may have been caused by the status of the autoimmune disorders, and the associated MN.

We investigated whether or not "low dose" metformin could prevent weight gain induced by pioglitazone. ⋯ This study indicates potential benefits of the addition of pioglitazone to "low dose" metformin in terms of improvement of glucose and lipid metabolism without weight gain.

A 28-year-old woman with severe ketoacidosis was admitted to our hospital on day 11 after giving birth. However, her HbA(1C) level was normal (5.2%) and both GAD and anti-insulin autoantibody were negative, and the WBC count was extremely high (57,500/ml) with immature leucocytes in the peripheral blood. ⋯ This is the first report of a patient with both fulminant type 1 diabetes and a leukemoid reaction. The mechanism that triggered the leukemoid reaction could not be clarified, but severe ketoacidosis may have been involved.

Case Reports
Successful treatment of intravascular large B-cell lymphoma diagnosed by bone marrow biopsy and FDG-PET scan.
Early diagnosis of intravascular large B-cell lymphoma (IVLBCL) is difficult, but is critical for longer survival for the patients. We report a case of IVLBCL that was diagnosed with the help of FDG-PET. A 76-year-old woman was referred to us for the evaluation of her elevated serum LDH. ⋯ FDG-PET imaging showed increased uptake of FDG in the vertebra, bilateral femurs, sternum, and iliac bones. A diagnosis of IVLBCL was made by bone marrow biopsy. She was successfully treated with rituximab and modified CHOP therapy.

Fleet enema (sodium phosphate, C. B. Fleet Co., Inc., Lynchburg, Virginia) is widely used for bowel preparation or constipation relief in the hospital and over the counter. ⋯ The patients with older age, bowel obstruction, small intestinal disorders, poor gut motility, and renal disease are contraindicated or should be administered with caution. We present a patient with old age and chronic renal failure who developed severe hyperphosphatemia and hypocalcemic tetany with coma after sodium phosphate enema. We recommend the use of alternative enema preparations, such as simple tap water or saline solution enemas, which can prevent fatal complications in high risk patients.
