We have occasionally encountered patients on nonsteroidal antiinflammatory drugs (NSAIDs) in whom double contrast barium studies revealed persistent flattening and stiffening of the distal greater curvature of the stomach. We therefore performed a study to determine the frequency of this finding in patients with NSAID-related gastropathy. Twenty-one cases of erosive gastritis, gastric ulcers, and/or gastric scarring associated with a known history of NSAID use were reviewed by two radiologists who made a joint decision regarding the presence or absence of greater curvature antral flattening. This finding was seen radiographically in five of the 21 patients (24%). Four of the five patients with antral flattening had associated erosions or ulcers in the gastric antrum. The remaining patient had antral flattening as an isolated finding. Our experience suggests that flattening of the greater curvature of the distal antrum, particularly if associated with erosive gastritis or gastric ulcers, is a useful radiologic sign of NSAID-related gastropathy. 相似文献

The impact of meat product recall events on consumer demand (beef, pork, poultry, and other consumption goods) in the USA is tested empirically. Beef, pork, and poultry recall indices are constructed from both the Food Safety Inspection Service's meat recall events and from newspaper reports over the period 1982–1998. Following previous product recall studies, recall indices are incorporated as shift variables in consumers’ demand functions. Estimating an absolute price version of the Rotterdam demand model, findings indicate that Food Safety Inspection Service's meat recall events significantly impact demand, and newspaper reports do not. Moreover, although elasticities related to recall events are significant they are small in magnitude relative to price and income effects. Any favourable effects on the demands of meat substitutes for a recall are offset by a more general negative effect on meat demand. The general negative effect indicates a shift out of meat to non-meat consumption goods. 相似文献

This paper examines the incidence and reasons for moonlighting with a focus on gender differences. The study specifies and estimates a bivariate probit model of labour supply and the decision to hold more than one job. It is found that the factors leading men and women to moonlight are similar. A wage decomposition analysis reveals that 93 percent of the differential between male and female moonlighters' wages is not explained by differences in characteristics, and little connection is found between an individual's human capital and their moonlighting wage. Finally, it is found that moonlighters are less likely to report their income. 相似文献
