[Reliability of low platelet counts--comparison of microscopic counts with automated hematology analyzer XE-2100].

Sysmex XE-2100 is an automated hematological analyzer with excellent features that can count platelets by both impedance and optical fluorescent method. Particularly, it is notable that platelet counts by optical fluorescent method (PLT-O) are automatically adopted when platelet counts by impedance method (PLT-I) are less than 50 x 10(3)/microl or platelets have abnormal distribution. We compared PLT-I with PLT-O, and also with microscopic counts, using the samples with thrombocytopenia.

Isolated hyperkalemia associated with cyclosporine administration in allogeneic stem cell transplantation for renal cell carcinoma.

Two patients with advanced renal cell carcinoma underwent allogeneic hematopoietic stem cell transplantation and received cyclosporine (CSP) as part of their immunosuppressive therapy. Despite adequate renal function, both patients developed hyperkalemia. CSP was the only pharmaceutical agent to which this electrolyte abnormality could be attributed.
