Patch test methods. II. Regional variations of patch test responses.

BACKGROUND AND PURPOSE: Physical therapist examination of pediatric clients or clients with neurological conditions often includes the observation of stereotypical movement patterns such as the asymmetrical tonic neck reflex and righting reactions. The purpose of this study was to investigate whether extremity and trunk responses to passive head turning could be documented in newborn infants. SUBJECTS AND METHODS: Forty-two newborns with no known medical problems were videotaped within 5 days of birth while an investigator turned their heads left and right. Videotapes were stopped at 5-second intervals to record the direction of head turn with the rest of the body obscured. A second investigator recorded trunk and extremity position with the head obscured. RESULTS: The direction of head turning affected upper- and lower-extremity position, with extension stronger on the face side. The direction of trunk convexity was also affected by head position, with the trunk convex to the side to which the face was turned. CONCLUSION AND DISCUSSION: Extremity responses and trunk responses to passive head turning can be documented corresponding to patterns reported for the asymmetrical tonic neck reflex and righting reflexes in neonates with no known medical problems more frequently than would occur by chance.

Evaluation of an intervention to reduce sun exposure in children: design and baseline results.

The Kidskin Study is a 5-year intervention study (1995-1999) involving 1,776 5- and 6-year-old children attending 33 primary schools in Perth, Western Australia. The aim of the study is to design, implement, and evaluate an intervention to reduce sun exposure in young children. There are three study groups: a control group, a "moderate intervention" group, and a "high intervention" group. The control schools receive the standard Western Australian health education curriculum, while the moderate and high intervention schools receive a specially designed curricular intervention. In addition, children in the high intervention group receive program materials over the summer holidays, when exposure is likely to be highest, and are offered sun-protective swimwear at low cost. The main outcome measure is the number of nevi on the back. Other outcomes include nevi on the chest (boys only), face, and arms, levels of suntanning, degree of freckling, and sun-related behaviors. At baseline, the three groups were similar with respect to nevi and freckling after adjustment for observer and month of observation. Sun exposure was slightly higher in the high intervention group. The groups were also similar with respect to most potential confounders, although they differed with respect to Southern European ethnicity and parental education.
