As polycythemia vera is a myeloproliferative syndrome, it is based on an autonomic increase in the proliferation of all hematopoetic cells--mostly of erythropoesis. An increase in blood viscosity induces disturbed microcirculation, resulting in headaches with clinical symptoms. So far, the headache
Herein, we report on a 44-year-old man who presented with cluster headache (CH)-like pain triggered by polycythemia vera (PV). He had severe unilateral head pain attacks lasting about 30 min not associated with cranial autonomic symptoms. After the exclusion of secondary etiologies, the patient was
Ruxolitinib was recently approved for the treatment of patients with polycythemia vera who are resistant/intolerant to hydroxyurea based on data from the RESPONSE studies. This phase 3b, Expanded Treatment Protocol study (NCT02292446) of ruxolitinib for hydroxyurea-resistant/intolerant patients with
Polycythemia vera (PV) is a myeloproliferative disorder most commonly associated with JAK2V617F mutation. Cerebral venous sinus thrombosis (CVST) has a wide range of etiologies and PV is one of them. CVST associated with PV has a poor prognosis. Some patients with classical PV lack
A 45-year-old male patient presented with gradual onset of headache, vomiting and blurring of vision of 28 days duration. Ophthalmological examination revealed normal anterior segment and pupillary reflex. No abnormality was detected in the vitreous. Optic disc showed features of advanced
Whole blood viscosity was determined in 10 patients with polycythemia vera and 129 normal controls using a cone-plate type rotational viscometer at 37 degrees C. Three of the patients with polycythemia vera exhibited vascular occlusions including cerebral and myocardial infarction. The remaining
We analyze symptoms, clinical course, and survival time of 86 patients with polycythemia vera treated between 1966 and 1987 at the medical polyclinic of the University Hospital of Zürich. The mean age of disease onset in 40 men and 46 women studied was 59 years. Most commonly the first symptoms were
We report the case of a 59 year old woman who presented with a six week history of worsening bifrontal headache. On CT brain the only abnormal finding was a partially empty sella potentially indicative of increased intracranial pressure. MRI found a large cerebral venous sinus thrombosis in the
A case of a 12-year-old girl presenting with headache and splenomegaly and fulfilling the diagnostic criteria of polycythemia vera is reported. Her peripheral blood values were as follows: hemoglobin 18 g/dL, red blood cells 7,000,000/mm3, while blood cells 22,000/mm, and platelets 1,248,000/mm3.
More than a century has elapsed since the appearance of the modern descriptions of polycythemia vera (PV). During this time, much has been learned regarding disease pathogenesis and PV-associated molecular aberrations. New information has allowed amendments to traditional diagnostic criteria.
Polycythemia vera (PV) is a chronic myeloproliferative neoplasm characterized by erythrocytosis and the presence of Janus kinase (JAK) 2V617F or similar mutations. This review summarizes the pathophysiology of PV, the challenges associated with traditional treatment options, and
Neurological symptoms (NS) of 33 patients diagnosed as suffering from polycythemia vera (PV) are described. 24 of them (73%) had NS at some point in their evolution, the most frequent being related to blood hyperviscosity (headache 51%, dizziness 36%, paresthesias 30%, sight alterations 21%). 5
The data of 140 patients with polycythemia vera during the period 1955--1975 were analyzed with regard to clinical signs and prognosis. The average age was 53,4 years. The sex ratio was 1.9:1 in favor of men. The most frequent symptoms were headache and vertigo. In more than half of the cases
The 'gold standard' for the treatment of polycythemia vera (PV) is to date undefined. We performed a retrospective analysis to evaluate the outcome of a cohort of PV patients treated with pipobroman (PB) at a single institution during a period of 20 years (November 1971-October 1991). During this
The quality of life (QoL) at the time of diagnosis of myeloproliferative neoplasm (MPN) has, to date, not been studied. One hundred and seventy-nine patients with MPN: 80 with essential thrombocythemia (ET), 73 with polycythemia vera (PV), 22 with primary myelofibrosis (PMF) and four with MPN
