The authors say the data confirm that patients with ischaemic strokes or transient ischaemic attacks enrolled in randomised controlled trials are only partly representative of patients in clinical practice.
A multifaceted distraction method seems to have been successful in reducing both the pain and discomfort of immunisation injections in schoolchildren aged 4-6 years. The intervention added verbal suggestions of diminished sensation and a visual focusing activity to the use of an ethyl chloride spray, which is an established method for reducing pain. The distraction materials included an improvised, plastic, multipronged arm gripper and a vibrating instrument that descended on the other arm, which provided the focusing task and visual distraction (Pediatrics 2009;124:e203-9, doi:10.1542/peds.2007-3466).
