How safe are school and bus environments? Parents’ perception of risks and hazards in the emirate of Dubai

© 2020 Institution of Occupational Safety and Health. The increasing numbers of school bus injuries in the United Arab Emirates have generated concerns over children’s safety on school buses and around school premises. A survey was administered on 550 parents or guardians, whose children use the school bus in public and private schools of Dubai. The main objective was to assess parental perceptions of the school bus and school environments. Parents identified several factors that pose a threat to bus safety including speeding cars, poor driving, lack of seat belt use enforcement, lack of supervision, motorists’ lack of understanding of school bus stop law, and children behaviour. Results suggest a deficiency in the communication of information regarding bus safety and behavioural policies. The study also highlights parents’ concerns over safety in relation to the school bus transport and around school premises, and emphasizes the need for safety education, as well as proper provision and communication of safety policies

Anatomical considerations and biomechanics in distal humeral hemiarthroplasty: are custom-made implants essential?

Distal humerus hemiarthroplasty is a somewhat debated and relatively new therapeutic option for distal humerus fractures, their sequelae, and other humeral degenerative conditions associated with a preserved radioulnar compartment. The anatomical variability of the distal humerus is the main issue that remains to be solved, particularly in view of the limited modularity of the only implant currently available. The clinical relevance of the mismatch between the native joint and the replacement joint has yet to be clearly demonstrated in the long term, though biomechanical studies have highlighted marked ulnar cartilage wear associated with such implants. Clinical studies are needed to understand whether custom-made implants can improve the results yielded by the implant available at present
