Clinical characteristics and outcomes of orbital fractures: a sex-based cohort analysis.

Purpose: This study aims to identify clinical similarities and differences between males and females presenting with orbital fracture.

Methods: Patient charts of adult orbital fracture cases diagnosed via computed tomography and referred by a level 1 trauma center to the McGill University Health Centre between August 2015 to January 2018 were examined and analyzed. Clinical parameters included age, sex, mechanism of injury, morphology of orbital fracture, symptoms and examination features, and rates of ocular pathology.

Impact of nanoscale roughness of titanium thin film surfaces on bacterial retention.

Two human pathogenic bacteria, Staphylococcus aureus CIP 68.5 and Pseudomonas aeruginosa ATCC 9025, were adsorbed onto surfaces containing Ti thin films of varying thickness to determine the extent to which nanoscale surface roughness influences the extent of bacterial attachment. A magnetron sputter thin film system was used to deposit titanium films with thicknesses of 3, 12, and 150 nm on glass substrata with corresponding surface roughness parameters of R(q) 1.
