Epidemiology of injuries due to tropical cyclones in Hong Kong: a retrospective observational study.
Tropical cyclones are huge circulating masses of wind which form over tropical and sub-tropical waters. They affect an average of 78 million people each year. Hong Kong is a large urban centre with a population of just over 7 million which is frequently affected by tropical cyclones. We aimed to describe the numbers and types of injuries due to tropical cyclones in Hong Kong, as well as their relation to tropical cyclone characteristics. ⋯ In tropical cyclone related injuries in Hong Kong the head and upper limb are the most commonly affected sites with falls and being hit by a falling or flying object being the most common mechanisms of injury. Hourly maximum gust appears to be more important that mean hourly wind speed in determining risk of injury. These findings have implications for injury prevention measures and emergency planning in Hong Kong and other regions effected by tropical cyclones.

The objective of this study is to provide estimates of firearm related injuries in children seeking care in hospital based emergency departments. ⋯ The current study used the largest all-payer hospital based emergency department dataset to provide national estimates of firearm related injuries amongst children in the United States during the year 2008 and highlights the public health impact of such injuries.

The American College of Cardiology (ACC) and the American Heart Association (AHA) have developed guidelines for perioperative assessment of patients in case of non-cardiac surgery. The aim of this study was to investigate if the preoperative cardiac evaluation of geriatric patients with hip fracture was in accordance with these guidelines and what the effects were on outcome. ⋯ Preoperative cardiac screening is frequently unnecessary after hip fracture, especially in patients with intermediate risk predictors and increases the delay to surgery. Delay of >48 h was associated with more cardiovascular complications and mortality postoperatively. The implementation of the ACC/AHA guidelines may prevent unnecessary cardiac consultations which reduces preoperative resources, delay to surgery and possibly decreases postoperative complications.
