BACKGROUND: Endoscopic laser coagulation of placental anastomoses is the first-line treatment for severe twin-to-twin transfusion syndrome. A recent randomized controlled trial reported that laser coagulation along the entire vascular equator was associated with a similar dual survival and survival of at least 1 twin compared with the group that was treated with the selective technique. In addition, there was a significantly lower incidence of postoperative recurrence of twin-to-twin transfusion syndrome and the development of twin anemia-polycythemia sequence in the equatorial group...

JAK-STAT signaling through the JAK2V617F mutation is central to the pathogenesis of myeloproliferative neoplasms (MPN). However, other events could precede the JAK2 mutation. The aim of this study is to analyze the phenotypic divergence between polycytemia vera (PV) and essential thrombocytemia (ET) to find novel therapeutics targets by a proteomic and functional approach to identify alternative routes to JAK2 activation. Through 2D-DIGE and mass spectrometry of granulocyte protein from 20 MPN samples, showed differential expression of HSP70 in PV and ET besides other 60 proteins...

More than 20,000 blood samples of individuals living in The Netherlands and suspected of hemolytic anemia or diabetes were analyzed by high resolution cation exchange high performance liquid chromatography (HPLC). Besides common disease-related hemoglobins (Hbs), rare variants were also detected. The variant Hbs were retrospectively analyzed by capillary zone electrophoresis (CZE) and by isoelectric focusing (IEF). For unambiguous identification, the globin genes were sequenced. Most of the 80 Hb variants detected by initial screening on HPLC were also separated by capillary electrophoresis (CE), but a few variants were only detectable with one of these methods...

The erythrocyte sedimentation rate (ESR) is a time-honored blood test, which assesses the degree of erythrocyte aggregation by acute phase proteins such as fibrinogen and immunoglobulins. Various intrinsic factors may influence the ESR, among them polycytemia, microcytosis or fibrinogen consumption lead to a decreased ESR, while anemia, macrocytosis or hypoalbuminemia lead to an increased ESR. The ESR still is a very valid test for the diagnosis of certain chronic diseases (polymyalgia, rheumatoid arthritis, multiple myeloma, septic arthritis and ostemyelitis) and the follow-up of certain chronic diseases (polymyalgia rheumatica, systemic lupus erythematodes, chronic infections, prostatic cancer, and Hodgkin's disease)...

A 55-year-old male with a history of positive HIV serology and polycythemia vera underwent coronary artery bypass graft surgery with normothermic extracorporeal circulation. Following heparin administration the activated clotting time (ACT) was 633 seconds (Hemocron with kaolin). Lower than expected arterial and venous oxygen partial pressures together with high pressure (350 mmHg) in the arterial line upstream of the oxygenator were observed. Because of these signs the oxygenator was changed during the procedure...

Neurological manifestations in polycytemia vera are common. However, chorea is an exceptionally revealing feature of this disease. We report a 78-year-old man who presented with headache and an abnormal movement disorder corresponding to chorea. Laboratory findings showed increased levels of hemoglobin at 20 g/dl and hematocrit at 62.3%. An elevated erythrocyte mass to twice the normal value demonstrated the absolute erythrocytosis. A JAK2 V617F gene mutation was identified. A diagnosis of polycytemia vera-associated chorea was obtained...

Polycythemia vera is a myeloproliferative disorder characterized by thrombotic complications both in the arterial and venous systems. We report the case of a 55-year-old patient affected by polycythemia vera, presenting with acute superior vena cava syndrome due to thrombosis of the upper part of the superior vena cava. Diagnosis was done clinically and by computed tomography scan and showed an unusual finding: an air bubble trapped in the brachiocephalic venous trunk. The patient underwent emergency surgery...

The sensibility to erythropoietin oferythroblastic islands of bone marrow which were made in different terms after the creation of transfusion polycytemia is researched. It turned out that the central macrophags of involuting erythroblastic islands are more sensible to erythropoietin than residual macrophags of bone marrow. The capability of residual macrophags to form erythroblastic islands is opened to the bigger inhibitory influence during the development of transfusion polycytemia than to the central macrjphags of involuting erythroblastic islands...

The effect of experimental inhibition of the erythropoiesis on ability of the erythroide "crown" cells of erythroblast islands of the bone marrow to respond to the erythropoietin by the increase of the proliferative activity was studied. It was discovered that this ability depended on the degree of the erythropoiesis inhibition and on the class of the erythroblast island maturity. In the culture of the erythroblast islands of the bone marrow on the second 24-hour period after transfusion polycytemia reproduction, the proliferative activity of the erythroid cells in response to brining of the erythropoietin to the culture increased more in the erythroblast islands of the first and second maturity classes than in the reconstructing the erythroblast islands...

Budd-Chiari syndrome still represents a challenge for the hepatologist with regard to its causes and its most effective therapy. Polycythemia vera is considered to be the most frequent condition causing the Budd-Chiari syndrome (10-40% of cases). We present a 34-year-old patient in post-partum who was admitted for right upper abdominal quadrant pain and asthenia. Laboratory data, abdominal echography and angioMRI all raised the suspicion of BCS, but it was in the haematological department that polycytemia vera was diagnosed as the cause of the hepatic condition...

In order to examine whether symptoms of iron deficiency anemia are due to the iron deficiency itself or the associated anemia, 34 patients with polycytemia vera (PV) treated with venesectio, who had iron deficiency but normal hemoglobin (Hb) levels, were given a questionnaire covering symptoms of iron deficiency including the international RLS-scale and the Fact-fatigue quality of life scale (QoL). We found a prevalence of pica of 11.7%, mouth paresthesias of 5.8% and rest-less legs 29.6% (RLS "normal" prevalence 10%)...

Evaluation of plasma viscosity has been underutilized in the clinical practice. Plasma viscosity is determined by water-content and macromolecular components. Plasma is a highly concentrated protein solution, therefore weak protein-protein interactions can play a role that is not characterized by electrophoresis. The effect of a protein on plasma viscosity depends on its molecular weight and structure. The less spheroid shape, the higher molecular weight, the higher aggregating capacity, and the higher temperature or pH sensitivity a protein has, the higher plasma viscosity results...

Increased PRV-1 mRNA expression and the presence of Jak2(V617F) mutation in peripheral blood granulocytes are specific markers for chronic myeloproliferative disorders (MPD), which facilitate the differential diagnosis between polycythemia vera (PV) and secondary erythrocytosis (SE) and may be helpful for monitoring treatment efficacy in MPD patients. We evaluated the presence of the Jak2V617F mutation and increased PRV-1 mRNA expression along with previously established markers - erythropoietin (EPO) independent colony formation (EEC) and erythropoietin level for diagnosis of PV and assessment of treatment efficiency...

Erythroblastic islands of the bone marrow are morpho-fuctional units of erythropoiesis. The functional state of the erythroblastic islands' erythrokariocytes and central macrophages of the bone marrow was first studied by estimation of the content of ribonucleoproteids in its cells (Brashe reaction). Acute blood loss and posttransfusion polycytemia lead to enhancement of the content of ribonucleoproteids in erythrokariocytes and central macrophages of the bone marrow of the rates.

Twin pregnancies are becoming common as a result of increased assisted reproduction. Studies have shown that the smaller twin of a pair is at greater risk of morbidity and mortality. Our aim was to determine if there is a relation between birth-weight discordancy and neonatal morbidity and mortality and to test the occurrence of respiratory distress syndrome (RDS) in discordant twins. For 5 years all twins admitted to our intensive care unit were included in the study. Discordance was calculated as the difference between twins' weights divided by the heavier weight...
