A growing body of evidence suggests that a majority of people with celiac disease and on a gluten-free diet can safely consume pure oats in moderate amounts; however, previous studies have indicated that the commercial oat supply in other countries, and in Canada to some extent, is contaminated with other grains. This study has confirmed that the commercial oat supply in Canada is heavily contaminated with gluten from other grains. Approximately 88% of the oat samples (n = 133) were contaminated above 20 mg kg(-1) and there were no differences between the oat types tested. Only one gluten-free variety of oats was analysed and it consistently provided negative results in all analyses. It is difficult to determine where the contamination originates, but there are possibilities for cross-contamination in the field, in the transport of the grain, in the storage of the grain, and in the milling and packaging facilities. It is clear from this study that only those products that have been certified 'pure' oats would be appropriate for a gluten-free diet. 相似文献

This study was undertaken to describe 'isolated' osteoarthritis of the scaphotrapeziotrapezoid articulation in six patients with chronic scapholunate ligament disruption. Each patient included for study had scapholunate ligament disruption with secondary dorsal intercalated segmental instability. Secondary volar tilt of the scaphoid appeared to be limited in each case by impaction and development of osteoarthritis at the scaphotrapeziotrapezoid articulation. Isolated osteoarthritis at the scaphotrapeziotrapezoid articulation may accompany chronic scapholunate ligament disruption, its identification should trigger a search for associated scapholunate ligament disruption in the absence of a known systemic arthropathy. 相似文献

It has been slightly less than 3 years since mutations of the RET proto-oncogene were identified in multiple endocrine neoplasia type 2. The period since the initial report has been one of intense activity with a wide spectrum of mutations identified in exons 10, 11, 13, 14, 15 and 16 of this gene. Recent studies have provided experimental evidence for an activating effect of the exon 11 and 16 mutations. Two questions are addressed in this report: the high rate of false positive tests in prospective screening studies and the implications for future interpretation of this test: and the mechanism of transformation in MEN 2. 相似文献
