We reported two cases of developed symptoms of Metoclopramide over-dose. Metoclopramide was given as Paracetamol due to look-a-like packaging. In Emergency Departments, reviewing the patient’s medications to prevent look-a-like complications should be done for all patients with suspected drug toxicity.展开更多

It is shown that the monetary steady state is more likely to be indeterminate under an active forwardlooking rule than under the corresponding backward-looking rule. It is also shown that backward-looking roles can render the monetary steady state unstable.展开更多

The aim of this study was to assess the effectiveness of SLE based on the risk of delayed bleeding after ESD. METHODS: A total of 310 lesions of gastric epithelial neoplasms treated by ESD were reviewed. The lesions were divided into two groups based on the risk of postprocedural bleeding estimated by Forrest classification. The high risk of rebleeding group(Forrest?Ⅰa,?Ⅰb and Ⅱa) required endoscopic treatment, while the low risk of rebleeding group(Forrest Ⅱb, Ⅱc and Ⅲ) did not. Delayed bleeding after ESD was investigated. RESULTS: Sixty-six lesions were included in the high risk of rebleeding group and 244 lesions in the low risk of rebleeding group. There were no significant differences in delayed bleeding between the high risk group(1/66) and the low risk group(1/244)(P = 0.38). The high risk of rebleeding group tended to be located more often in the mid-third and had higher appearance of flat or depressed shape than the low risk group(P = 0.004 and P = 0.006, respectively). CONCLUSION: SLE with pre-emptive prophylactic endoscopic treatment is still effective in preventing delayed bleeding after ESD.展开更多
