[Coincidence of multiple myeloma and renal clear cell adenocarcinoma].

There are only casuistic reports about the coincidence of renal carcinoma and lymphoproliferative diseases. We report a case of 59-year old patient who simultaneously developed renal clear cell carcinoma and IgG kappa multiple myeloma. After nephrectomy the progression of multiple myeloma was observed.

[Observation of D-dimer levels in serum of patients with acute leukemia].

The blood coagulation and fibrinolysis disorders are common complications observed in patients with acute leukemias, particularly in acute myelogenous leukemia. These abnormalities are mediated by thromboplastic substances released from the blast cells and the alteration of hemostatic properties of vascular endothelium. The plasma concentration of D-dimer (cross-linked fibrin degradation products), measured by enzyme immunoassay, using monoclonal antibodies, serves as a specific marker of the coagulation activation and fibrinolysis system.

Disseminated nocardiosis as a complication of Evans' syndrome.

Nocardiosis is an opportunistic infection caused by gram-positive, weakly acid-fast filamentous aerobic organisms. Three species cause infection in man: N. asteroides, N.
