Interrater and intrarater reliability of ultrasonographic measurements of acromion-greater tuberosity distance in healthy people.

Acromion-greater tuberosity (AGT) distance could potentially be used to assess rotator cuff tears and shoulder subluxation in patients with poststroke hemiplegia. The aim of this study was to assess the interrater and intrarater reliability of ultrasonographic measurements of AGT distance in healthy people prior to testing on patient populations. Twenty healthy individuals (9 male, 11 female) with a mean age of 21 years (SD ± 2) were recruited.

The moral universe of injecting drug users in the era of AIDS: sharing injecting equipment and the protection of moral standing.

Recent work on HIV counselling suggests that the protection of the moral status of the recipient is a key factor in the successful uptake of advice. This study suggests it may be equally important in the uptake of health promotion messages. A discourse analysis of the talk of 20 young injecting drug users (IDUs) identified a contradiction between their asserted self-identity as careful and socially responsible injectors, and their admission of risky lending and borrowing of injecting equipment.
