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.

Small cell carcinoma of the bile duct system is extremely rare, and surgical procedures have been complicated by early hematogenous dissemination. In this study, we report a patient with small cell carcinoma of the bile duct system presenting with jaundice. ⋯ We performed radiation therapy of a total of 30 Gy, resulting in a marked decrease of serum neuron specific enolase levels and amelioration of jaundice, which had been resistant to drainage procedures. The patient was then treated with combined chemotherapy of cisplatin and CPT-11, which resulted in the disappearance of the tumor mass by image tests.

To analyze a risk factor for the onset of fulminant bacterial infection. ⋯ Despite the different type of bacteria, the onset of fulminant bacterial infection depended upon depressed bacterial phagocytosis in the liver or spleen. Underlying chronic illnesses should be identified as a predisposing common risk factor. It is important to understand the relations between underlying chronic illness and the onset of fulminant infection.
