Objective-To determine the current prevalence of hyperuricaemia and gout in New Zealand Maori and Europeans for comparison with previous studies. Methods-342 Maori and 315 European men and women aged 15 years and older were studied by personal interview and a musculoskeletal system examination. The 1977 ARA criteria for gout in a survey setting were used and serum uric acid was determined by a uricase method. The data were compared with those of previous New Zealand studies. Results-Gout was significantly more common in Maori (6.4%) than Europeans (2.9%) ( = 3.6%, 95% confidence interval 0.4 to 6.8) and in Maori men (13.9%) than in European men (5.8%) ( = 8.1%, 95% CI 1.0 to 15.2). Hyperuricaemia was significantly more common in Maori men (27.1%) than in European men (9.4%) ( = 17.7%, 95% CI 8.3 to 27.1) and in Maori women (26.6%) than in European women (10.5%) ( = 16.1%, 95% CI 8.5 to 23.7). At least 14% of hyperuricaemic individuals were receiving diuretics, of whom 78% were women. Comparison with previous studies shows that the prevalence of gout has increased in both Maori and Europeans, particularly in men. In Maori men the prevalence of gout has risen from 4.5-10.4% previously to 13.9%, and in European men from 0.7%-2.0% previously to 5.8%. Clinical diVerences included a stronger family history, earlier age at onset, and a higher frequency of tophi and polyarticular gout in Maori than Europeans. Of those with gout, 62% of Maori and 63% of Europeans were hyperuricaemic on the day surveyed and six (19.4%) were on diuretics. Treatment of gout was inadequate in most cases. Conclusions-Hyperuricaemia and gout remain common among Maori. Of concern is that the prevalence of gout appears to be on the increase, not only in Maori but also in Europeans in New Zealand.

A study was conducted on members of the Cape Performing Arts Board (CAPAB) professional ballet company to determine the prevalence of hypermobility and to document the injuries sustained over a ten year period. If forward flexion, which is acquired through training, is excluded as a parameter the difference in hypermobility between dancers and controls is not statistically significant. Considering the stresses imposed on the musculoskeletal system, the number of injuries was surprisingly low. Ligamentous injuries about the ankle and knee were both common and accounted for the major morbidity. There were minor differences in the nature and severity of injuries in the male and female dancers. Back injuries, fractures and osteoarthrosis were uncommon and shin splints was not recorded in any of the dancers.

A follow-up study of ballet dancers was conducted to determine the influence of 4 years additional training on articular mobility using Beighton's method. The score increased in 25 (45.5%) of the 55 dancers reexamined. Acquired forward flexion accounted for this increase in 21 (84%) of the 25 dancers. These 21 dancers had had significantly less training than had the 30 dancers who could forward flex when examined initially (P less than 0.0001), showing that forward flexion is acquired through training. There were significantly more hypermobile individuals among dancers who had continued dancing than among those who had stopped (P less than 0.03). However, only 2 (16.7%) of 12 dancers who had progressed in their careers were hypermobile. We conclude that 1) most ballet dancers are able to forward flex, 2) forward flexion is usually acquired and develops after 4 or more years of training, 3) the mobility score may assist in predicting who will continue dancing, but that 4) there is no association between hypermobility and dancing excellence.
