Case presentation: a novel way of treating acute cauliflower ear in a professional rugby player

D J M Macdonald, N Calder, G Perrett, et al

Acute auricular haematoma is a common problem in rugby players and can be difficult to treat due to re-accumulation of the fluid and can subsequently cause the unsightly cauliflower ear. We present a case of auricular haematoma affecting the central part of the pinna in a professional rugby player. This was treated successfully by aspiration and the use of silicone splints which allowed the player to continue training and competing.

The exercise addiction inventory: a quick and easy screening tool for health practitioners

M D Griffiths, A Szabo, A Terry

Background: Exercise addiction is not routinely screened for probably because available instruments take a long time to administer, their scoring may be complicated, and their interpretation is not always obvious. A new psychometric instrument has been developed that is capable of identifying people affected by, or at risk of, exercise addiction: the exercise addiction inventory (EAI). A preliminary report showed the EAI had good reliability and validity.

Objectives: To test further the EAI’s psychometric properties and show that it would be quick and simple to administer by general practitioners.

Methods: A sample of 200 habitual exercisers were given the EAI and two existing exercise addiction scales (obligatory exercise questionnaire; exercise dependence scale). Two weeks later, another sample of 79 exercisers were administered the EAI to determine the test-retest reliability of the questionnaire.

Results: The original data from the preliminary report were reanalysed to determine the split half correlation of the EAI.

This was found to be 0.84 (Guttman split-half coefficient). A correlation between weekly frequency of exercising and EAI scores was also determined, and it was found that the two variables shared 29% of the variance (r2  =  0.29). The test-retest reliability of the scale was found to be very good (0.85).

Conclusions: The EAI is a valid and reliable tool which would be capable of helping general practitioners to quickly and easily identify people affected by, or at risk of, exercise addiction.
