Secondary Immune Thrombocytopenic Purpura Due to Primary Epstein- Barr Virus Infection.

A rare complication of infectious mononucleosis is immune thrombocytopenic purpura (ITP). The majority of people affected by Epstein-Barr Virus (EBV) are below the age of 30, while ITP is usually seen with peaks of incidence in the elderly and children. The unique case of an otherwise healthy 22-year-old female will be discussed, with an initial presentation of ecchymosis, rash, and epistaxis, and was subsequently found to have severe thrombocytopenia.

Scratching below the surface: wound healing and alanine mutagenesis provide unique insights into interactions between eristostatin, platelets and melanoma cells.

To study the molecular mechanism of the disintegrin eristostatin, cellular functional studies were performed using ten recombinant alanine mutants. ADP-induced platelet aggregation revealed critical contributions of seven residues within the 'RGD loop' (R24, R27, G28, N31) and C-terminus (W47, N48, G49) of this disintegrin. Using an in vitro scratch wound healing assay, four human melanoma cell lines yielded similar results when exposed to wildtype eristostatin.
