Case Reports
Use of intravenous immunoglobulin G to treat spontaneous heparin-induced thrombocytopenia.
Spontaneous heparin-induced thrombocytopenia (HIT) is a rare but serious prothrombotic syndrome characterized by thrombosis, thrombocytopenia, and strong platelet-activating HIT antibodies in the absence of heparin exposure, and is frequently characterized by a suboptimal response to standard therapies. Here, we present the first report of intravenous immunoglobulin G (IVIG) use in a patient with spontaneous HIT. ⋯ These results suggest that IVIG may be a useful adjunctive therapy in spontaneous HIT.

Case Reports
Massive transfusion of low-titer cold-stored O-positive whole blood in a civilian trauma setting.
Based on the improved outcomes achieved with fresh whole blood in cases of military trauma as well as with 1:1:1 transfusion strategies for massive traumatic hemorrhage in civilian settings, there has been resurgent interest in using whole blood for civilian trauma patients. There have been reports of giving up to 4 units of low-titer cold-stored O-positive to these patients. This is the first modern report of a massive transfusion with unrestricted low-titer group O whole blood (LTOWB) use in a civilian trauma patient. ⋯ This is the first report of a massive transfusion for civilian trauma based on cold-stored whole blood in the recent era. While this patient suffered a tremendous burden of traumatic injury and his recovery is not yet complete, his LTOWB resuscitation was successful. Frequent monitoring of coagulation status with thrombelastography during utilization of LTOWB is indicated because the efficacy of its components (particularly platelets) is not yet fully understood.
