Helmet promotion in the emergency room following a bicycle injury: a randomized trial.

Head injury is the leading cause of serious morbidity and mortality in bicycle accidents. There is good evidence to recommend helmets, yet few children wear them. Following a survey of children presenting to the emergency room with a bicycle injury, helmet promotion was evaluated in a randomized trial. The intervention consisted of physician counseling and take-home pamphlets. The study involved 334 children: 161 in the intervention group and 173 in the control group. In a follow-up telephone call, 2 to 3 weeks later, only 9.3% of the intervention group had purchased helmets, compared with 8.0% of the control group. Families in the intervention group received further counseling during the telephone contact, resulting in one additional purchase at 6-week follow-up. Evidence that a bike injury motivates cyclists to purchase helmets, and the influence of the self-administered questionnaire most likely account for the high purchase rate in the control group. Surprisingly, the helmet promotion intervention, including follow-up phone counseling, made no further impact. The results probably are best explained by a "double threshold" effect. Certain families were easily encouraged to buy a helmet, whereas others were far from ready to adapt this fairly recent innovation as routine cycling equipment. The findings suggest that physicians interested in helmet promotion would do better to participate in the design and implementation of multidisciplinary community campaigns.

Unity is strength in joint research project.

The advent of the purchaser/provider split produced a number of challenges for a coordinated approach to supporting research. This article describes a collaboration between North Derbyshire Health Commission and Chesterfield and North Derbyshire Royal Hospital NHS Trust in bringing together purchaser and provider. A research interest group spanning purchaser and provider organisations has been responsible for a number of initiatives including training days, a research database and a resource pack for would-be researchers which aim to raise the profile of research across North Derbyshire.

Randomized clinical trial comparing different iodine interventions in school children.

OBJECTIVE: The purpose of this trial was to compare three different iodine interventions. DESIGN: School children aged 8-10 years were randomized into one of three groups: group A was provided with iodized salt by researchers with an iodine concentration of 25 ppm; group B purchased iodized salt from the market; and group C was similar to group B with the exception that they were given iodized oil capsules containing 400 mg iodine at the beginning of the study. Salt iodine content was measured bimonthly for 18 months and indicators of iodine deficiency were measured at baseline and 6, 9, 12 and 18 months after randomization. RESULTS: The prevalence of abnormal thyroid volumes, based on the World Health Organization (WHO) body surface area reference >97th percentile, was 18% at baseline and declined to less than 5% by 12 months in groups A and C, and to 9% after 18 months in group B. Results for goitre by palpation were similar. The median urinary iodine was 94 microg l(-1) at baseline and increased in all groups to > 200 microg l(-1) at the 6-month follow-up. CONCLUSIONS: In this population of school children with initially a low to moderate level of iodine deficiency, the group receiving salt with 25 ppm (group A) was not iodine deficient on all indicators after 18 months of study. When the iodine content of the salt varied, such as in group B, by 18 months thyroid sizes had not yet achieved normal status.

Production responses to bovine somatotropin in northeast dairy herds.

The commercial response to bovine somatotropin was examined in northeast dairy herds from 1990 to 1998 (4-yr preapproval and 4-yr postapproval). With DHI records and Monsanto customer files, a control group (never purchased Posilac) and a bovine somatotropin (bST) group (used on at least 50% of cows) were identified. A total of 340 herds were involved and, over the 8-yr period, there were over 80,000 cows, 200,000 lactations, and 2 million test days. Herd management comparisons demonstrated the response to bST was relatively constant each year of the postapproval period. Assuming 100% of cows were supplemented, response to bST over a 305-d lactation equaled 894 kg of milk, 27 kg of milk fat, and 31 kg of milk protein. Comparisons of lactation curves were used to identify where the bST response occurred in the lactation cycle. Analysis demonstrated the responses in milk, milk fat, and protein yield were minimal in the early phase of lactation, and then gradually increased until reaching a plateau over the last half of the lactation cycle. Persistency of lactation was also improved by bST, indicating the opportunity exists to extend lactation with combined use of bST and altered reproductive management. Average age and days in milk did not differ between control and bST herds. Thus, stayability and herd-life of animals were not altered by bST treatment. Somatic cell count (SCC) linear scores were minimally affected in herds utilizing bST and the pattern of SCC over the lactation cycle was unaffected. Overall bST improved lactation yield and persistency consistently over the 4-yr postapproval period with no effects on cow stayability and herd-life.
