Diagnostic Performance of a New Rapid Lateral Flow Immunoassay in Patients Suspected of Heparin-Induced Thrombocytopenia and Its Clinical Consequences.

We prospectively evaluated the diagnostic accuracy of a new rapid assay (STic Expert HIT) alone or in combination with a clinical score in 90 HIT-suspected patients. The 4Ts score was calculated, and ELISA and serotonin-release assay (SRA) were performed; the average time taken for test results were 2 and 5 days for ELISA and SRA, respectively. The STic test was performed in our laboratory as an evaluation exercise and the result was available in 1 hour, but results were not communicated to the clinicians so as to not influence management.

Perioperative challenges of atrial fibrillation.

Purpose Of Review: The management of atrial fibrillation has seen marked changes in recent years. This is the result of better knowledge of the pathophysiology and risks factors for atrial fibrillation, better stratification for thromboembolic and bleeding risks, changing practices in anticoagulation management, and the development of new antiarrhythmic drugs. This article focuses on these new issues, with particular attention to their relevance in the perioperative period.

[Atrial fibrillation: from cardiology to perioperative management].

Atrial fibrillation (AF) is the most frequent arythmia. During the perioperative period and in intensive care units, management of patients with AF is frequent and difficult. As in cardiology, two main issues are present: the risk of acute hemodynamically instability and the risk of thromboembolic complication.
