Pseudohyperkalemia and platelet count in thrombocythemia

Platelet count and aging.

Platelet density distribution in essential thrombocythemia.

Essential thrombocythemia (ET) is characterized by high platelet counts and a slightly increased bleeding risk. Why severe hemorrhage does not occur more frequently is not known. Variations of platelet density (kg/l) depend mainly on cell organelle content in that high-density platelets contain more α and dense granules. This study compares ET patients (n = 2) and healthy volunteers (n = 2) wit...

Platelet Satellitism in a Three and Half Year Old Girl with Hemolytic Anemia and Normal Platelet Count

Platelet adherence surrounding leucocytes in a rosette formation or platelet satellitism is a rare phenomenon. This finding has been observed almost exclusively in Ethylenediaminetetraacetic acid treated blood at room temperature. The mechanism underlying this phenomenon is not fully understood. In many reports of platelet satellitism platelets clump to polymorphonuclear neutrophils in healthy...

Platelet activation and inhibition in polycythemia vera and essential thrombocythemia.

Persistently enhanced platelet activation has been characterized in polycythemia vera (PV) and essential thrombocythemia (ET) and shown to contribute to a higher risk of both arterial and venous thrombotic complications. The incidence of major bleeding complications is also somewhat higher in PV and ET than in the general population. Although its efficacy and safety was assessed in just 1 relat...

The association of platelet count and mean platelet volume (MPV) index with types of stroke

Background: Stroke is known to be the third most prominent cause of death in the developing countries and the most common debilitating neurologic disease. This study aimed to investigate the association of platelet count (PC) and mean platelet volume (MPV) index with various stroke types. Methods: This cross-sectional study was carried out on patients over the age of 18 years who presented wit...
