AIM:To perform a single-center analysis of all double balloon endoscopy (DBE) related cases of pancreatitis identified prospectively from a recorded DBE-complication database. METHODS:From November 2003 until January 2007, 603 DBE procedures were performed on 412 patients, with data on complications recorded in a database. The setting was a tertiary care center offering DBE. DBE was performed from the antegrade or retrograde route. Out-come measurements included age, gender, medication, indication, DBE-endoscope type, insertion depth, proce-dure duration, findings, interventions, post-procedural abdominal pain, and post-procedural hospitalization. RESULTS:This is the largest single-center study report-ing on post-DBE pancreatitis prospectively. Six patients (1.0%) developed post-DBE pancreatitis, all after antegrade DBE. There was no association with gender, duration of the procedure or type of endoscope. The mean age was 51.9 years (range 25-78). Four patients had severe pancreatitis. Of these, two had inflammatory signs in the body-tail region, one had pancreatitis in the tail region, and the total pancreas was involved in one. CONCLUSION:The incidence of post-DBE pancreatitis in our series is higher than previously reported. We found no relation with DBE-endoscope type. The inflammatory changes occurred in the body-tail region of the pancreas, suggesting that post-DBE pancreatitis is caused by repetitive mechanical strain on the pancreas.

AIM: To define the association between Hashimoto’s thyroiditis and coeliac disease in Dutch patients. METHODS: A total of 104 consecutive patients with Hashimoto’s thyroiditis underwent coeliac serological tests (antigliadins, transglutaminase and endomysium antibodies) and HLA-DQ typing. Small intestinal biopsy was performed when any of coeliac serological tests was positive. On the other hand, 184 patients with coeliac disease were subjected to thyroid biochemical (thyroid stimulating hormone and free thyroxine) and thyroid serological tests (thyroglobulin and thyroid peroxidase antibodies). RESULTS: Of 104 patients with Hashimoto’s thyroiditis, sixteen (15%) were positive for coeliac serology and five patients with documented villous atrophy were diagnosed with coeliac disease (4.8%; 95% CI 0.7-8.9). HLA-DQ2 (and/or -DQ8) was present in all the five and 53 patients with Hashimoto’s thyroiditis (50%; 95% CI 43-62). Of 184 patients with coeliac disease, 39 (21%) were positive for thyroid serology. Based on thyroid biochemistry, the 39 patients were subclassified into euthyroidism in ten (5%; 95% CI 2-9), subclinicalhypothyroidism in seven (3.8%; 95% CI 1.8-7.6), and overt hypothyroidism (Hashimoto’s thyroiditis) in 22 (12%; 95% CI 8-16). Moreover, four patients with coeliac disease had Graves’ disease (2%; 95% CI 0.8-5) and one patient had post-partum thyroiditis. CONCLUSION: The data from a Dutch population confirm the association between Hashimoto’s thyroiditis and coeliac disease. Screening patients with Hashimoto’s thyroiditis for coeliac disease and vice versa is recom- mended.

具估计,40％～60％的人类癌症,其病因与内源性或外源性的性激素作用有关。激素在致癌过程中的作用日益引起人们的关注。流行病学和激素与致癌物诱发肿瘤的动物实验均说明激素是一种促癌因子。激素促肿瘤发生似与对细胞增生和分化的作用有关。但其致癌或辅助致癌的作用尚有争议,有待进一步阐明。激素诱导靶组织的肿瘤发生,究竟是渐成说抑或是基因毒在靶组织的肿瘤激发上起主要作用,目前仍不清楚。
