Identification of MCAM/CD146 as the target antigen of a human monoclonal antibody that recognizes both epithelioid and sarcomatoid types of mesothelioma.

The prognosis for patients diagnosed with mesothelioma is generally poor, and currently available treatments are usually ineffective. Therapies that specifically target tumor cells hold much promise for the treatment of cancers that are resistant to current approaches. We have previously selected phage antibody display libraries on mesothelioma cell lines to identify a panel of internalizing human single chain (scFv) antibodies that target mesothelioma-associated, clinically represented cell surface antigens and further exploited the internalizing function of these scFvs to specifically deliver lethal doses of liposome-encapsulated small molecule drugs to both epithelioid and sarcomatous subtypes of mesothelioma cells.

Calciphylaxis and bone scintigraphy: case report with histological confirmation and review of the literature.

We present a patient with a history of end-stage renal disease, who developed skin lesions in the bilateral calves a month after the initiation of hemodialysis. The lesions were biopsied, and the histological findings were consistent with a diagnosis of calciphylaxis. The patient had a baseline pretreatment bone scan that showed extensive systemic disease.
