Polycythæmia Rubra Vera

Reno-vascular disease in polycythaemia rubra vera.

Hypertension and polycythaemia rubra vera commonly occur in the same patient. This is regarded as coincidence and the hypertension does not respond to correction of polycythaemia. We report a case of renal artery stenosis occurring simultaneously with polycythaemia rubra vera and suggest that renovascular occlusive disease should be excluded in such patients with refractory hypertension.

Polycythaemia rubra vera and hairy cell leukaemia in the same patient: studies on the spleen.

The first association of polycythaemia rubra vera (PRV) and hairy cell leukaemia (HCL) is reported. The secretion by spleen cells in short term culture of IfGlambda to the exclusion kappa demonstrated that despite aberrant surface marker studies the HCL was a monoclonal tumour of B cells. Chromosomal studies on splenic cells were not able to demonstrate the common clonal origin of the two tumours.

New diagnostic criteria for polycythemia rubra vera: Artificial neural network approach

An ANN-based approach in optimal selection of input parameters for Polycythemia Vera (PV) diagnostics and classification based on this new input set is presented in this paper. Results showed that a trained artificial neural network, known as a robust modeling system, gives the solution for classification of “gray” PV diagnostic zones that occur in practice, and therefore it obtain high quality...
