Polycythemia and Thrombocytosis
Primary Care: Clinics in Office Practice, 2016Myeloproliferative neoplasms (MPNs) are diseases of excess cell proliferation from bone marrow precursors. Two classic MPNs, polycythemia vera (PV) and essential thrombocytosis (ET), are conditions of excess proliferation of red blood cells and platelets, respectively.

POLYCYTHEMIA AND HYDRONEPHROSIS
Annals of Internal Medicine, 1961Excerpt Twenty-five years ago an association between polycythemia and renal carcinoma was suspected and reported in the literature.1Two years ago a case was described of polycythemia associated wit...

The diagnostic approach to a patient with polycythemia has been greatly simplified by the introduction of new genetic testing in addition to traditional tests, such as measurement of red cell mass and serum erythropoietin (Epo) level. Clonal erythrocytosis, which is the diagnostic feature of polycythemia vera (PV), is almost always associated with a ...

COMPOUND 8103-Abbott (A-8103), a neutral amide of piperazine (NSC-25154), 1, 4-bis (3-bromopropronyl) piperazine, was shown to have a favorable effect upon neoplastic disease including polycythemia rubra vera by Bond et al in 1962.1The antitumor properties of the neutral amide were first demonstrated in transplanted adenocarcinoma, Ca 755 in mice, and ...

Polycythemia vera (PV) is the most common myeloproliferative neoplasm (MPN), the ultimate phenotype of the JAK2 V1617F mutation, the MPN with the highest incidence of thromboembolic complications, which usually occur early in the course of the disease, and the only MPN in which erythrocytosis occurs. The classical presentation of PV is characterized by

The PCV of a llama increased from 50.8 to 74.0% during a 19-month period. The llama remained clinically normal unless stressed, when it would become dyspneic and tachypneic. Thoracic auscultation revealed sounds consistent with pneumonia, but were probably attributable to pulmonary congestion resulting from polycythemia.

Pediatrics, 1982
The article by Ramamurthy and Brans (Pediatrics 68:168, 1981) on the criteria for diagnosis and treatment of neonatal polycythemia was most interesting. Their conclusions that there are considerable and unpredictable differences between capillary, peripheral, venous, and umbilical venous hematocrit levels in the same neonate might be of much importance

Polycythemia is defined as a venous hematocrit above 65%. The relationship between viscosity and hematocrit is almost linear till 65% and exponential thereafter. Increased viscosity of blood is associated with symptoms of hypo-perfusion. The hematocrit in a newborn peaks at 2 hours of age and decreases gradually after that. The etiology of polycythemia

Polycythemia vera (PV) is one of the myeloproliferative diseases, and, as such, is an example of clonal hematopoiesis. The progeny of a single, abnormal, hematopoietic stem cell gain a growth advantage over their normal counterparts resulting in overproduction of red cells generally accompanied by overproduction of granulocytes and platelets as well ...

Erythropoietin and Polycythemias
Annals of Internal Medicine, 1981Excerpt To the editor: Koeffler and Goldwasser (1) have applied a sensitive radioimmunoassay for erythropoietin to the problem of distinguishing between primary and secondary polycythemias.
