30,185 | [Lemierre syndrome: a diagnosis to keep in mind]. | Lemierre syndrome (also called post-anginal sepsis or necrobacillosis) is an uncommon complication of oropharyngeal infections for which early recognition and aggressive therapy is mandatory, since it is potentially life-threatening. Due to it's rarity, with a prevalence of 0.8 cases per million in the general populati... |
30,186 | Rehabilitation in Guillian Barre syndrome. | Guillian Barre syndrome (GBS) is the most common form of neuromuscular paralysis. It mostly affects young people and can cause long-term residual disability.</AbstractText>This article outlines the rehabilitation treatment for patients recovering from GBS.</AbstractText>Recovery from GBS can be prolonged. Early rehabil... |
30,187 | Periprocedural management of anticoagulation in patients on extended warfarin therapy. | Patients receiving chronic anticoagulation therapy pose a clinical challenge when therapy needs to be interrupted for surgical or invasive procedures. Maintaining anticoagulation places them at risk of serious bleeding complications, whereas discontinuing anticoagulation puts them at risk of thromboembolic complication... |
30,188 | Role of thrombophilia in deciding on the duration of anticoagulation. | It is now possible to identify hereditary risk factors in a substantial percentage of patients presenting with a venous thrombotic event. Discovery of the factor V Leiden and prothrombin G20210A mutations has greatly increased the percentage of patients in whom venous thrombosis can be attributed to hereditary thrombop... |
30,189 | Mortality rates and risk factors for asymptomatic deep vein thrombosis in medical patients. | The clinical importance of asymptomatic proximal and distal deep vein thrombosis (DVT) remains uncertain and controversial. The aim of this retrospective, post-hoc analysis was to examine mortality and risk factors for development of proximal DVT in hospitalized patients with acute medical illness who were recruited in... |
30,190 | Elevated plasma osteoprotegerin levels are associated with venous thrombosis and bleeding in patients with polycythemia vera. | Patients with polycythemia vera (PV) have an increased risk for the development of thrombohemorrhagic complications. The pathogenesis of these complications is still unclear. An important role in vascular disease has recently been attributed to osteoprotegerin (OPG). It has been shown that various tissues of the cardio... |
30,191 | Treatment of 51 pregnancies with danaparoid because of heparin intolerance. | Pregnant patients with acute venous thrombosis or a history of thrombosis may need alternative anticoagulation, when heparin intolerance occurs. Only limited data on the use of the heparinoid danaparoid are available in literature. We reviewed the use of danaparoid in 51 pregnancies of 49 patients identified in literat... |
30,192 | Conformational Asn187Asp/Lys antithrombin variants and thrombosis. Clinical and biological features in 13 new heterozygotes. | Antithrombin Rouen VI (N187D) is a rare conformational thermolabile variant. The unique symptomatic carrier reported in the literature developed 3 thrombotic events during pregnancy, in each case in a context of pyrexial infection. In fresh plasma, antithrombin activity and antigen level were normal but in vitro experi... |
30,193 | Long lives, short indications. The case for removable inferior cava filters. | Vena cava filters have been in use for decades to prevent pulmonary embolization from deep venous thrombosis. These filters have been shown to be effective, with fairly low rates of filter migration, fracture and thrombosis. However considering that filters remain in situ for the life of the patient and that studies do... |
30,194 | Dilation of the minor arterial circle of the iris preceding rubeosis iridis during retinal vein occlusion. | To report in four patients with retinal vein occlusion the presence of biomicroscopically visible circulation in the minor arterial circle of the iris, preceding rubeosis iridis in two cases.</AbstractText>Retrospective observational case series.</AbstractText>Four patients with ischemic type of central or hemi-central... |
30,195 | Retinal blood flow analysis using intraoperative video fluorescein angiography combined with optical fiber-free intravitreal surgery system. | To report a new method to perform intraoperative video fluorescein angiography (VFA) using an optical fiber-free intravitreal surgery system (OFFISS) and retinal blood flow analysis during surgery.</AbstractText>Observational case series.</AbstractText>Four eyes of four patients with macular edema as a result of branch... |

In all the cases of brain infarction due to carotid dissection, history of trauma, immediate typical headache after the accident, development of infarction 24 hours after the acciden... |
30,197 | [Conus medullaris and cauda equina infarct in the course of thrombosis of deep veins of lower extremities]. | A 61-year man showed symptoms of conus medullaris and cauda equina syndrome. MR examination of spine and spinal cord SL section showed changes in medullary cone of ischaemial character. Spinal cord injury was probably caused by thrombosis of spinal cord venous vessels, which developed, with diabetes of the second type,... |
30,198 | [Essential thrombocythemia and retinal vein thrombosis]. | Essential thrombocytosis is a disorder of the hematopoietic stem cell that causes proliferation of platelets. We report two cases: a 72-year-old woman with ischemic retina and tortuous and white veins in the superior retina and diffuse hemorrhages in the inferior retina with blot hemorrhages scattered throughout the eq... |
30,199 | Access monitoring does not really improve outcomes. | It is widely accepted that hemodialysis access monitoring combined with preemptive percutaneous transluminal angioplasty (PTA) improves outcomes. The many studies that have evaluated monitoring during the last decade provide an opportunity to examine whether this hypothesis is valid. Because synthetic grafts are more l... |
