Acquired hemophilia A (AHA) is a rare bleeding disorder caused by autoantibodies against factor VIII (FVIII). Treatment with clopidogrel is a cause of AHA, but its clinical course is unknown. Recently, we treated a 65-year-old man who was hospitalized for cerebellar infarction and had a prolonged activated partial thromboplastin time (aPTT) with soft tissue oozing after 3 weeks of clopidogrel u...

The Aha! experience is not a unitary construct, and several different dimensions have been proposed as its constituents. However, a systematic analysis of how much each purported dimension predicts the overall Aha! experience is needed. Presented with a large set of difficult problems (magic tricks), participants were asked to rate their solving experience with regard to suddenness in the emerg...

Recombinant activated factor VII (rFVIIa) is the bypassing agent used in the first-line hemostatic therapy for acquired hemophilia A (AHA); however, the occurrence of thrombotic complications in rFVIIa-treated AHA patients was recently reported to be 2.9-6.5%. Therefore, the investigation of the proper administration of rFVIIa for AHA is needed. In the present study, we retrospectively investig...

BACKGROUND Immune system involvement is suggested as an underlying cause for Doberman hepatitis (DH) based on female predisposition, lymphocyte infiltration, abnormal hepatocyte expression of major histocompatibility complex class II antigens, and homozygosity for dog leukocyte antigen DRB1*00601. OBJECTIVE To measure serum antinuclear antibodies (ANA) and serum antihistone antibodies (AHA) i...

the latest american heart association (aha) statement for preventing infectious endocarditis, has not recommended prophylactic antibiotic therapy prior to fiberoptic bronchoscopy (fb) except for patients with preexisting predisposing cardiac conditions. our aim was to determine the incidence of bacteriemia and fever following fb in our experience and compare with those which have been mentioned...

Acquired hemophilia A (AHA) is a severe bleeding diathesis caused by the appearance of autoantibodies against coagulation factor VIII (FVIII). Clinical features of inherited and acquired hemophilia are spontaneous as well as posttraumatic deep muscle-joint and mucosal bleeding. 50% cases of AHA are associated with autoimmune diseases, malignancies, medications and the postpartum period, but in ...

Formation dynamics of antibodies to rat erythrocytes (REs) and auto-antibodies to mouse erythrocytes were studied in an experimental model of autoimmune hemolytic anemia (AHA) in mice. The experimental conditions of AHA were simulated in a mathematical model of an immune network. It was found that maximal production of auto-antibodies and antibodies to REs do not synchronize. Antiserum, obtaine...

Acquired hemophilia A (AHA) is a rare coagulopathy caused by autoantibodies to coagulation factor VIII (FVIII). Most patients with AHA have been previously healthy; however, a variety of morbidities have been associated with the condition including pregnancy. A 40-yr-old woman visited our institution with extensive hematoma on the right hip area. Her medical history revealed no personal or fami...
