[Aortic arch interruption and cutaneous PO2].

In three neonates with cardiac failure and coarctation the cutaneous PO2 (cPO2) has been measured during the administration of a high concentration of oxygen. One sensor was fitted to the skin just below the right clavicle (preductal) and the other on one of the legs (postductal). The difference in the cPO2 provided evidence for a large right to left shunt through the duct. This finding in conjunction with the clinical syndrome of co-arctation is characteristic, in our view, of atresia of the aortic arch. The results of the test, with clinical and echocardiographic details enable more accurate decisions to be made before catheterisation and surgery.

Evaluation of a four-year bicycle helmet promotion campaign in Quebec aimed at children ages 8 to 12: impact on attitudes, norms and behaviours.

OBJECTIVE: This study evaluated a four-year bicycle helmet promotion campaign. METHODS: Children's attitudes, social norms, intentions to wear a bicycle helmet as well as helmet ownership were measured. Evaluation was based on a pre-experimental static group comparison design repeated at two (1991) and four years (1993) after implantation, with a non-randomized control group. 3,424 students completed a self-administered questionnaire (experimental: 2,097, control: 1,327). RESULTS: The program had a significant impact on helmet ownership (1989: 4%; 1991: 26%; 1993: 56%). The program was the principal predictor of high intention to use a bicycle helmet. Time was the principal predictor of ownership with exposure to the program being the next predictor. CONCLUSION: This study showed that time is an important factor in bicycle helmet acquisition, and that a long-term community-based program can accelerate the process of adopting this behaviour.
