Incidence and cause of fractures in European districts.
AIMS: To compare fracture rates in European districts. SETTING: Geographically defined areas of Wales (Swansea and Neath Port Talbot), Norway (Harstad, Trondheim, Stavanger, and Drammen), Sweden (Jamtlands), and Finland (Porvoo). METHODS: Surveillance of fractures at emergency departments and hospitals and linkage with population data. Comparison of age adjusted and crude rates. Calculation of confidence intervals for ratios. RESULTS: A total of 4113 fractures occurred in 167 560 children during 1996. Fracture rates in south Wales (36 per 1000) were substantially higher than in Scandinavian districts (which were similar). Limiting analysis to the most severe injuries to correct for the possibility of ascertainment bias reduced some of the excess rate in Wales: the Welsh:Scandinavian fracture ratio was 1.82 (95% confidence interval: 1.64 to 2.03). CONCLUSIONS: Fracture rates in Welsh children are substantially higher than in Scandinavian children.

Children's fractures: a population based study.
OBJECTIVE: To measure the incidence of childhood fractures in a defined population. SETTING: Accident and emergency (A&E) departments covering the Swansea and Neath Port Talbot areas of South Wales in 1996. METHODS: Linkage of data from A&E departments with population data to produce fracture incidence rates by anatomical site and cause in children aged 0-14 years. RESULTS: During 1996, 2463 new fractures occurred in 2399 residents yielding a fracture rate of 36.1/1000 children. Fractures were more common in boys than girls and increased with age in both groups. Sports and leisure activities accounted for 36% of fractures, assaults for 3.5%, and road traffic accidents 1.4%. Fractures of the radius/ulna were most frequent (36%). CONCLUSIONS: The fracture rate in South Wales children is twice the rate reported in previous studies. Further research is required to elucidate the reasons behind this high rate. Many fractures could be prevented by the use of safer surfaces in school playgrounds, and wrist protection in in-line skaters and possibly in soccer players.

Discrimination of motion in depth trajectory following acute alcohol ingestion.
Evoked potentials were recorded at four scalp sites O1, O2, T5, T6; before and after the consumption of one of two alcohol dose levels, to the occurrence of disparate stimuli in dynamic random dot stereograms. Twenty young adult subjects, all of whom had vision which was normal or corrected to normal, were randomly assigned to the two dosage groups. Subjects viewed stimuli which embodied crossed disparity and followed one of three trajectories in depth. The task was to distinguish between and identify, by specific button presses, these trajectories. One half of the stimuli were presented with monocular cues to motion in depth (dark condition); in the remainder only stereoscopic depth information was available (uniform condition). Responses to both conditions showed alcohol-related reduction of evoked responses across all sites. It was concluded that the visual systems associated with the processing of motion in depth were susceptible to alcohol effects, as revealed by reductions in the amplitude of evoked responses.
