In South Africa the two sports responsible for virtually all serious injuries to the cervical spine are rugby and diving. For some years I have been analysing the clinical and radiological features of patients who have sustained cervical spinal injuries while participating in these two activities. I am surprised by the interest, publicity and controversy surrounding rugby injuries and the almost total lack of concern about the more common and equally tragic cases of traumatic spinal cord injury and paralysis due to diving accidents.
Over the past few years, there has been an increasing incidence of distress in runners participating in long distance races (marathon distance and further). It has been very difficult to assess these reports accurately as they have been conveyed by word of mouth or by brief, sometimes sensational newspaper reports. These instances have been descriptionbed as ""collapse"", ""heat stroke"", ""exhaustion"", even ""heart attack"".
Asthma is a disease that is characterised by increased responsiveness of the bronchial tree to a number of stimulae. Of the known triggers of asthma, allergens and exercise have been extensively studied. Both are powerful and natural occurring precipitants, but exercise is a potential factor in the daily life of every asthmatic.
