[MANAGEMENT OF VENOUS THROMBOEMBOLISM: WHICH DRUG, WHAT DOSE AND FOR HOW LONG].

Venous thromboembolism is a major cause of morbidity and mortality. The main initial therapy for thromboembolism is anticoagulation for a period of three months (active treatment period). The aim of treatment beyond three months is prevention of recurrence.

Cardiac Manifestations of Antiphospholipid Syndrome With Focus on Its Primary Form.

Antiphospholipid syndrome (APS) is a multisystem autoimmune disease most commonly associated with recurrent arterial and venous thromboembolism and recurrent fetal loss. Other possible antiphospholipid antibody (aPL)-related clinical manifestations include cardiac involvement. The heart can be involved through immune mediated and /or thrombotic mechanisms.

The complexity of an overlap type resistant cryoglobulinemia: a case report and review of the literature.

Type I cryoglobulinemia is associated with B cell proliferative diseases, whereas essential mixed cryoglobulinemia is classically associated with infections, malignancy, and autoimmune diseases, but may be idiopathic. Prognosis in patients with grave manifestations and renal involvement is often poor. We report a case of a 40-year-old woman, 2 weeks post-partum for pre-eclampsia who was hospitalized with nephritic syndrome and acute renal failure.

Laryngeal Side Effects of Tyrosine Kinase Inhibitors.

Objectives: Tyrosine kinase inhibitors (TKIs) are common targeted drugs, used in the treatment of hematological and solid malignancies. These drugs present a multitude of potential adverse effects. Laryngeal manifestations, including laryngeal edema, secondary to TKIs treatment have not been well studied, despite their potential lethality.

[Laboratory evaluation of lupus anticoagulant in Israel].

Lupus anticoagulants (LAC) are antibodies which are detected by a prolongation of phospholipid-dependent coagulation assays, and are associated with thrombotic events and pregnancy complications in patients with the antiphospholipid syndrome. The antiphospholipid syndrome is defined by arterial or venous thrombosis and/or pregnancy morbidity and by laboratory diagnosis of antiphospholipid antibodies. The laboratory diagnosis is based on LAC and/or anticardiolipin and/or anti-beta2-glycoprotein I antibodies present in plasma, on two or more occasions at least 12 weeks apart.

Oxidative stress in red blood cells, platelets and polymorphonuclear leukocytes from patients with myelodysplastic syndrome.

Low-risk myelodysplastic syndrome (MDS) is characterized by cytopenia, mainly anemia, because of ineffective hematopoiesis. Some of the patients with ineffective erythropoiesis, with or without ring sideroblasts in their bone marrow, develop severe anemia requiring frequent blood transfusions and consequently develop iron overload. Excess free iron in cells catalyses the generation of reactive oxygen species (ROS) that cause cell and tissue damage.

No evidence for myocardial iron overload in multitransfused patients with myelodysplastic syndrome using cardiac magnetic resonance T2 technique.

The method of cardiovascular T2 magnetic resonance imaging (MRI) allows in vivo estimation of iron in the heart and liver and was used to measure the degree of iron overload in 10 transfused MDS patients (average 90 blood units) and in 3 patients with congenital hemolytic anemia. In all MDS patients iron overload was found in the liver but not in the heart. Patients with congenital anemias had iron in both organs despite iron chelation.

[Anthrax--an overview at 2002].

Bacillus anthracis, the causative agent of anthrax, is well known in human history as a major cause of disease in domestic and wild animals and as a rare condition in humans. For the last seventy years, anthrax was developed and occasionally stored as an agent of biological weapon arsenal in numerous countries. The incubation period in humans is 1-6 days and the disease may be present as three distinct clinical syndromes: cutaneous, inhalational, and gastrointestinal disease.
