For example, MRIs take longer and can require a child to be sedated occasionally, he said. ‘Ultrasound takes a particular skill set as children are not simply small adults,’ Jones added. ‘If an inexperienced ultrasound technician and radiologist will be the only option when facing a child with feasible appendicitis, for example, then a CT scan might be a better option because it is less subjective.’ Many conditions would require a CT scan, Jones explained, primarily when doctors have to look for an injury or infection deep in the body for something urgent. ‘Often it truly is the very best imaging technique and the benefits far outweigh the small risk of potential cancer decades later on,’ Jones said. ‘A classic example in pediatrics will be a young child with indications of bleeding within the brain or dangerously increased intracranial pressure, such as occurs with accidental or abusive head trauma.’ In some cases, skipping a CT scan because of concerns about side effects might mean missing the cause of a problem, resulting in serious immediate problems or death even, Jones said.The researchers tracked teen smoking prices from 1997 to 2013. The nation’s remarkable progress in reducing youth smoking since 1997 is excellent news, however the battle is definately not over, stated Vince Willmore, vice president for communications at Marketing campaign for Tobacco-Free Kids. This research reminds us that people know exactly what to do to further reduce smoking: boost tobacco taxes, enact smoke-free laws and regulations, fund effective prevention applications and implement hard-hitting media campaigns. These established strategies should be strengthened and continued, Willmore added. The researchers called for targeted prevention programs and policies that involve parents also, academic institutions, communities and the media.
