Windows 10 is clearly different enough from Windows 8.1 to be considered a different operating system, which hasn't always been the case with Microsoft's version releases. For desktop users, Windows 10 has more in common with Windows 7 than 8.
Thrombocythemia: Introduction. Thrombocythemia: A haematological disorder in which there is excessive proliferation of platelet precursor cells, resulting in increased numbers of platelets in the blood. More detailed information about the symptoms, causes, and treatments of Thrombocythemia is available below.
In this condition, faulty stem cells in the bone marrow make too many platelets. What causes this to happen usually isn't known. When this process occurs without other blood cell disorders, it's called essential thrombocythemia. A rare form of thrombocythemia is inherited. (Inherited means the condition is passed from parents to children through the genes.) In some cases, a genetic mutation may cause the condition. In addition to the bone marrow making too many platelets, the platelets also are abnormal in primary thrombocythemia. They may form blood clots or, surprisingly, cause bleeding when they don't work well. Bleeding also can occur because of a condition that develops called von Willebrand disease.
