serum calcium accompanying a fall in red blood cell count following treatment with phenylhydrazine. We were stimulated by this report to make some additional studies of the calcium metabolism in polycythemia, but the work was halted in its incipiency by our inability to confirm the findings of Brown and Roth. Serum calcium determinations were made in nine cases of typical polycythemia vera usin...
Polycythemia vera is a rare case confronted in dentistry with scarcely available reports. Hence scrupulous knowledge of it inevitable. It myeloproliferative disorder characterized by excessive proliferation erythroid elements, granulocytic and megakaryocytic cells. Here, the blood viscosity increases leading to menace thrombosis. The medications often used include cytoreductive agents like hydr...
Haemangioblastomas are uncommon tumours that usually occur in the cerebellum and, less commonly, in the intramedullary spinal cord. The extramedullary spinal canal is an uncommon location for these tumours. Also haemangioblastoma at this site is not known to be associated with polycythemia. We present the clinical, imaging, and histological findings of an adult patient with extramedullary spina...
Two families with polycythemia inherited as an autosomal dominant trait are described. Serial hemoglobin determinations in multiple family members and RBC volume measurements in selected affected subjects documented their polycythemia. Measurements of arterial p02s, p50s, and blood oxygen affinity were normal in all affected individuals from each family who were tested. Erythropoietin (EPO) lev...
Thrombosis is one of the major complications of polycythemia vera. Seventeen patients with polycythemia vera in good hematologic control were evaluated for abnormalities of the coagulation system. Activation of the intrinsic coagulation cascade was suggested by low levels of factor XII, prekallikrein, and kallikrein inhibitors in 12 of 17 patients. The group also demonstrated a significant inc...
To assess the possible contribution of host immune responses to the exertion of Fv2-associated resistance to Friend virus (FV)-induced disease development, we inoculated C57BL/6 (B6) mice that lacked various subsets of lymphocytes with FV containing no lactate dehydrogenase-elevating virus. Fv2(r) B6 mice lacking CD4(+) T cells developed early polycythemia and fatal erythroleukemia, while B6 mi...
In this study, we report here a rare case of polycythemia and cRCC in the same patient, which may be helpful in understanding clinical features and molecular mechanisms underlying VHL-mutation-associated cRCC and polycythemia induced by germline mutation of HIF2A. Firstly, we identified a rare but well studied germline mutation resulting in polycythemia in HIF2A (c.1609G>A, p.Gly537Trp) in the ...
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% ...
Lacunar infarction is traditionally ascribed to lipohyalinosis or microatheroma. We report the case of 40-year-old man, without traditional risk factors for ischemic stroke, who presented to the Emergency Department with recurrent episodes of transient right-sided weakness and paresthesia. Lacunar infarction was confirmed on diffusion-weighted MRI and blood tests showed a marked polycythemia. Q...
Thrombosis is one of the major complicafiltration on 4% agarose. Fibrin degradations of polycythemia vera. Seventeen pation products were normal and antitients with polycythemia vera in good thrombin III levels were slightly elevated, hematologic control were evaluated for It appears that patients with polycythemia abnormalities of the coagulation system. vera have chronic activation of the coa...
