pathophysiologic classification of blood disorders

ABSTRACT

In these classifications of haemopoietic diseases, we tried at the same time to integrate them together. This was done by dividing them first into disorders of haemopoiesis and of haemostasia. We integrated together the different cellular disorders under the heading of haemocytopenia, haeroocytosis and hoemocythemias. The unity of these disorders, the use of one single classification for the different causes of decrease of the erythrocytes, leucocytes and thrombocytes facilitates the approach to the disorders and stress their correlation. Also, the use of one single classification for the causes of increase of the erythrocytes and thrombocytes serves the same aim. The classification given to proliferative diseases group together disorders as the leukaemias, lymphomas and reticulosis which seemed previously not related. Grouping together the manifestations of the different disorders of haemopoiesis obviate their unity and facilitate their description and memorization. The same goes for the manifestations of the haemorrhagic disorders. Such an approach makes the understanding and the diagnosis of the haemopoietic diseases easier
