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
Superior vena cava syndrome caused by an intravascular thrombosis due to underlying prostate carcinoma.
Superior vena cava (SVC) syndrome is usually caused by malignant tumors or their lymph node metastases oppressing a SVC. However, we encountered a case of SVC syndrome that was caused by a thrombus in the SVC, which we considered as a manifestation of Trousseau's syndrome triggered by underlying prostate cancer. A 60-year-old man patient complained of facial swelling. ⋯ Histological examination of both percutaneous transluminally aspirated thrombus via a catheter through jugular vein and the axillary lymph nodes included metastatic prostate cancer. Although the ultrasonic and MR images were not compatible with the prostate cancer, needle biopsies from the prostate established the diagnosis. The SVC syndrome as an initial manifestation of underlying unknown malignancy and also due to intravascular thrombosis caused by cancer metastasis to the vascular wall is extremely uncommon.

Comparative Study
Long-term intensive insulin therapy for Japanese patients with type 2 diabetes mellitus.
To determine the clinical usefulness of long-term intensive insulin therapy in Japanese patients with type 2 diabetes. ⋯ Our results indicated the clinical usefulness of intensive insulin therapy over the long term in Japanese patients with type 2 diabetes and that such therapy could be especially useful for previously untreated patients.

Case Reports
An unusual case of acute brucellosis presenting with Coombs-positive autoimmune hemolytic anemia.
Brucellosis can mimic several primary hematological diseases. Mild anemia and leukopenia have been frequently associated with acute brucellosis, but pancytopenia, thrombocytopenia, and hemolysis are less frequently seen. To our knowledge, brucellosis has not previously been described in association with Coombs-positive autoimmune hemolytic anemia. ⋯ The patient responded well to short-term pulse corticosteroid therapy followed by antibrucellosis treatment. We suggest that Brucella infection may be the probable cause of the immune hemolytic anemia in this patient. Therefore, the differential diagnosis of Coombs-positive autoimmune hemolytic anemia should include brucellosis, especially in areas where the disease is endemic.

An 85-year-old man patient was admitted to the hospital complaining of fever and bilateral leg pain with swelling and erythema. A laboratory investigation revealed leukocytopenia, thus suggesting sepsis. Gram negative rods were detected in the specimen from the affected skin and empiric antibacterial therapy was initiated. ⋯ An autopsy revealed necrotizing fasciitis due to P. aeruginosa. This is a rare case and its clinical presentation was atypical. The clinical diagnosis of this infection may be difficult, and therefore such cases warrant the careful attention of physicians.
