It has been suggested recently that financial links between manufacturers of sports drinks and professional Sports Science organisations in North America have suppressed information on the existence and ways of preventing an epidemic of exercise-associated hyponatraemia (EAH). This article reviews evidence for the prevalence of both biochemical and clinical hyponatraemia. ⋯ However, this information has been widely reported, both in North America and in other parts of the world. Claims of an 'epidemic' seem unwarranted, and there is no solid evidence supporting the claim that information has been suppressed because of ties between sports scientists and sports drink manufacturers.

The paper reports on a symposium on sports helmets and presents a synthesis of information and opinion from a range of presenters and disciplines. A review of the literature shows that helmets play an important role in head injury prevention and control. Helmets have been shown to be very efficacious and effective in a range of sports and in preventing specific head injury risks, especially moderate to severe head injury. ⋯ It was identified that athletes, families and sports organisations can benefit from access to information on helmet performance. The importance of selecting the appropriate-sized helmet and ensuring that the helmet and visor were adjusted and restrained optimally was emphasised. The translation pathway from the science to new and better helmets is the development of appropriate helmet standards and the requirement for only helmets to be used that are certified to those standards.

Exercise-associated collapse (EAC) commonly occurs after the completion of endurance running events. EAC is a collapse in conscious athletes who are unable to stand or walk unaided as a result of light headedness, faintness and dizziness or syncope causing a collapse that occurs after completion of an exertional event. ⋯ On review of the evidence, EAC is now believed to be principally the result of transient postural hypotension caused by lower extremity pooling of blood once the athlete stops running and the resultant impairment of cardiac baroreflexes. Once life-threatening aetiologies are ruled out, treatment of EAC is symptomatic and involves oral hydration and a Trendelenburg position - total body cooling, intravenous hydration or advanced therapies is generally not needed.

Economic burden of physical activity-related injuries in Dutch children aged 10-12.
Injuries in children occur most often in physical activity-related activities. A lot of these injuries result in direct and indirect costs. A detailed overview of the economic burden of those injuries in children is lacking. ⋯ Physical activity-related injuries are common in children and result in medical costs. Injuries that lead to the highest costs are those that occur during leisure time activities and upper extremity injuries. Intervention programmes for children to prevent upper extremity injuries and leisure time activity injuries may reduce direct (ie, healthcare) and indirect costs.

To describe the impact of an expanded primary care-based sports medicine clinic on referrals to an orthopaedics clinic and to describe the patients seen and procedures performed. ⋯ Very few patients with musculoskeletal pathology were referred by a primary care-based sports medicine clinic to an orthopaedics clinic. Of the referred patients, sports medicine physicians and orthopaedists frequently agreed on the need for surgery. Expansion of a primary care-based sports medicine service could help relieve overburdened orthopaedics departments of patients with conditions not requiring surgery.
