INTRODUCTION The cause of chest pain in patients presenting to the emergency room often remains unclear. We present a case of essential thrombocythemia as a novel cause of atypical chest pain, which responded dramatically to a simple treatment intervention. CASE PRESENTATION A 54-year-old patient presenting with atypical chest pain was found to have essential thrombocythemia as a cause for he...

Patients with essential thrombocythemia often complain of various subjective neurological symptoms. This prospective study aims to assess their incidence and response to therapy. Among 37 consecutive patients with essential thrombocythemia, 11 presented with neurological symptoms. Among them 4 had thrombotic events, 7 complained of transient or fluctuating subjective symptoms, and one had both....

Primary myelofibrosis shows histological and pathogenetic overlap with essential thrombocythemia and polycythemia vera. Several diagnostic classifications have been proposed for primary myelofibrosis, although little is known about their clinical utility. In a comparison of three recent classifications, overall concordance was 79%. Inclusion of raised serum lactate dehydrogenase categorized 9% ...

To observe the effect of the new World Health Organization (WHO) criteria on the incidence of myeloproliferative neoplasms, we performed a retrospective study of a population-based registry in the Côte d'Or area, France, from 1980 to 2007. A total of 524 myeloproliferative neoplasms were registered for the 1980-2007 period, including 135 polycythemia vera, 308 essential thrombocythemia and 81 i...

N INCREASED NUMBER of circulating platelets ( thrombocytosis, thrombocythemia, piastrinenlia ) Ilas been known to occur in response to a variety of nonhematobogic conditions. Thrombocythemia, a term applied to persistently increased platelet levels, is also an integral part of certain diseases primarily affecting the blood-forming organs. The authors have had the opportunity to study a young wo...

INTRODUCTION Thrombotic thrombocytopenic purpura and idiopathic thrombocytopenic purpura are two well recognized syndromes that are characterized by low platelet counts. In contrast, essential thrombocythemia is a myeloproliferative disease characterized by abnormally high platelet numbers.The coexistence of thrombotic thrombocytopenic purpura and idiopathic thrombocytopenic purpura in a single...
