Solitary subdural osteomas: Systematic review of the literature with an illustrative case.

Background: Subdural osteomas represent an extremely rare entity with only 20 cases described to date. Despite the typical benign behavior, these tumors can grow to compress the brain and occasionally detach from the dura mater.

Methods: A systematic search of the literature was performed in compliance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines.

Clinical utility of tissue Doppler imaging in prediction of atrial fibrillation after coronary artery bypass grafting.

Background: Atrial systolic dysfunction in patients with coronary artery disease might influence the development of atrial fibrillation after coronary artery bypass grafting (CABG). Tissue Doppler imaging of the mitral annulus during atrial systole has proved to quantify, accurately, left atrial contractile function. Therefore, the aim of the present study was to investigate the correlation between preoperative left atrial dysfunction assessed by tissue Doppler and postoperative atrial fibrillation after CABG.
