Rush University Medical Center, Chicago, IL, USA.
Avascular necrosis (AVN) of the femoral head accounts for up to 10% of all total hip arthroplasties performed annually. Typically associated with intravascular coagulation, AVN is extremely rare in patients with bleeding disorders such as hemophilia B. In this report, we describe the therapeutic management of a 46-year-old male with hemophilia B, presenting with chronic left hip pain and AVN of the femoral head.

Disseminated intravascular coagulation (DIC) is a complex and serious condition characterized by widespread activation of the coagulation cascade, resulting in both thrombosis and bleeding. This review aims to provide a comprehensive overview of DIC, emphasizing its clinical significance and the need for improved management strategies. We explore the primary causes of DIC, including sepsis, trauma, malignancies, and obstetric complications, which trigger an overactive coagulation response.

Introduction: Autoimmune hemolytic anemia (AIHA) is a condition in which there is decreased survival of red blood cells (RBC) due to the destruction of RBC by autoantibodies. AIHA is classified into warm, cold, and mixed according to temperature sensitivity. The antibodies may be immunoglobulin G, immunoglobulin M, immunoglobulin A, or complement proteins, and hemolysis may be intravascular or extravascular.
