Skatepark-related injuries in a southern California skatepark and their associated short-term disability and healthcare utilization.

OBJECTIVE: To assess the types of injuries, the extent of short-term disability, and the degree of healthcare utilization in skatepark-injured patients. DESIGN: The study design was a prospective case series with 1-year follow-up. SETTING: Level I trauma center and emergency department located in Orange, California. PARTICIPANTS: Subjects age 7 years or older who sustained an injury at a local skatepark and were treated in our emergency department were included in the study. Ninety-five subjects were enrolled with a total of 97 injury encounters. MAIN OUTCOME MEASUREMENTS: Types of injuries, extent of short-term disability, degree of healthcare utilization. RESULTS: Emergency department diagnoses included 57 fractures, 6 dislocations, 15 strains/sprains/contusions, 7 lacerations, 2 dental fractures, 9 head injuries, and 1 intra-abdominal injury. Nine of the emergency department encounters terminated in admission to the hospital. The peak sum of time lost from school, work, parental time lost from work, and specialist visits were found to occur at 1 month postinjury. Similarly, the number of postinjury follow-up medical visits peaked at the 1-month interval. Subject disability was largely categorized as moderate initially, with a subsequent reduction to no disability by the 9th postinjury month. CONCLUSION: Skatepark-related injuries can yield substantial time lost from school and work, considerable short-term disability, and an increase in healthcare resource utilization.

Radioactive impact in sediments from an estuarine system affected by industrial wastes releases.

A big fertilizer industrial complex and a vast extension of phosphogypsum piles (12 km2), sited in the estuary formed by the Odiel and Tinto river mouths (southwest of Spain), are producing an unambiguous radioactive impact in their surrounding aquatic environment through radionuclides from the U-series. The levels and distribution of radionuclides in sediments from this estuarine system have been determined. The analyses of radionuclide concentrations and activity ratios have provided us with an interesting information to evaluate the extension, degree and routes of the radioactive impact, as well as for the knowledge of the different pathways followed for the radioactive contamination to disturb this natural system. The obtained results indicate that the main pathway of radioactive contamination of the estuary is through the dissolution in its waters of the radionuclides released by the industrial activities and their later fixation on the particulate materials. Tidal activity also plays an important role in the transport and homogenization along the estuary of the radioactivity released from the fertilizer plants.

Child safety seat knowledge among parents utilizing emergency services in a level I trauma center in Southern California.

OBJECTIVE: To determine the level of child safety seat (CSS) and airbag safety knowledge in parents who utilize emergency care services for their children and to determine factors that influence knowledge of safe transportation of children. METHODS: A prospective survey study was conducted in a 42 000-visit-per-year Level I trauma center and emergency department (ED) in Southern California from May through October 2000. Subjects were parents of ED-registered children (< or =6 years). Research assistants administered the survey in the subject's native language. Parent knowledge of age-appropriate restraint use and airbag safety was collected. RESULTS: Six hundred fifty-five subjects were enrolled. Most parents (97%) reported a regular source of pediatric medical care, and 57% had a previous ED visit. Eighty-six percent reported owning a CSS or booster seat. Eighty-one percent were aware that infants in rear-facing CSSs should never be placed in front of an airbag. Only 46% knew that a child weighing 40 to 60 lb should travel in a booster seat, and 59% knew that the State law required CSS use for children up to 4 years and weighing up to 40 lb. When knowledge scores were examined by ethnicity, fluency in English, income, and years of education, fluency was found to have the greatest influence on both CSS and airbag knowledge. CONCLUSIONS: Although nearly all of our subjects admitted that their children had a regular source of care, many parents showed evidence of lack of knowledge of CSS and airbag safety. Furthermore, many parents were not familiar with the state law regarding child restraints. Our findings suggest that parents of small children who utilize emergency care services could benefit from child passenger safety education during their ED visit and that non-English media and materials may be important to reaching this population.
