    Notes: regina freestone peaches from california were given low postharvest doses of gamma radiation (65-75 krads) and were compared with non-irradiated controls approximately one month after harvest. Practiced judges were used, with a technique of minimal cross-sensory interference, as an analytical tool to guide subsequent instrumental analysis. Strong differences were found in odor and components of taste not associated with sweetness. Lesser trends were noted for firmness and appearance. Untrained subjects also detected gross sensory differences.

    Notes: Bing cherries from California were given low postharvest doses of gamma radiation (60-80 Krads) and were compared with nonirradiated controls during a period 3-11 days after harvest. Irradiated cherries showed a greater degree of shrivelling, a trend to be softer on chewing and also exhibited flavor differences. Trends for consistent differences in firmness tested manually, darkness of skin color and degree of brown blemishing were not noted.

    Notes: Navel oranges from two locations in California were given low postharvest doses of gamma radiation (60 - 80 Krads) and compared with nonirradiated controls for taste, flavor, odor, firmness, degree of orange color, degree of brown blemishing, ease of peeling and intactness of the membranes on sectioning. Practiced judges were used as an analytical screening tool using minimal cross-sensory interference, while untrained subjects were used to determine whether changes might be distinguished by‘nonexperts’. Greatest differences were found for degree of blemishing, lesser differences for flavor by mouth and odor and some trends for taste, color, texture and ease of peeling.

    Notes: Background : Clopidogrel causes significantly less symptomatic peptic ulcer disease and gastrointestinal bleeding than low-dose aspirin in average-risk patients. The gastrotoxicity of clopidogrel in patients with active peptic ulcer disease is unknown.Aim : To compare the incidence of unhealed ulcers in patients receiving clopidogrel or aspirin.Methods : Patients with aspirin-induced peptic ulcer disease treated with omeprazole (20 mg/day) were randomized to receive clopidogrel (75 mg/day) or to continue with low-dose aspirin. Success was defined as ulcer/erosion healing at the eighth week.Results : One hundred and twenty-nine patients were recruited (69 received clopidogrel and 60 continued with aspirin). Thirty-one (45%) in the clopidogrel group and 25 (42%) in the aspirin group had a minor gastrointestinal bleed. No ulcer showed an adherent clot or visible vessel. The distributions of peptic ulcer disease were similar in the clopidogrel and aspirin groups (gastric ulcer: 41% vs. 40%; duodenal ulcer: 10% vs. 12%; gastric ulcer + duodenal ulcer: 6% vs. 3%; gastritis: 32% vs. 37%; duodenitis: 4% vs. 7%; gastritis + duodenitis: 0% vs. 2%). Clopidogrel and aspirin were re-started after 0.86 ± 1.79 and 0.44 ± 1.60 days, respectively (P = 0.170). Three (4%) patients stopped clopidogrel due to drug rash. Using per protocol analysis, the treatment success rates of clopidogrel and aspirin were 94% (62/66) and 95% (57/60), respectively.Conclusions : In patients with aspirin-associated peptic ulcer disease of low to moderate grade, both early conversion from aspirin to clopidogrel and continuation of aspirin are safe.

    Notes: Background:  In average-risk patients, the new anti-platelet agent, clopidogrel, causes less upper gastrointestinal adverse events than aspirin. However, there are no safety data on the use of clopidogrel in high-risk patients.Aim:  To evaluate the safety of clopidogrel in patients with peptic ulcer disease in a retrospective cohort longitudinal study.Methods:  During the period from January 2000 to May 2002, 70 patients who were prescribed clopidogrel (75 mg/day) for a previous history of non-aspirin-related peptic ulcer disease or a history of aspirin-related gastrointestinal complications (dyspepsia or peptic ulcer) were recruited. The occurrence of ulcer complications (bleeding/perforation/obstruction) was the primary end-point.Results:  After a median follow-up of 1 year, nine patients (12%) developed gastrointestinal bleeding and one had a perforated peptic ulcer. Clopidogrel-associated gastrointestinal bleeding was significantly more common in patients with a history of gastrointestinal bleeding than in those without (22% vs. 0%; P = 0.007; odds ratio, 1.3; 95% confidence interval, 1.1–1.5).Conclusions:  Clopidogrel is associated with a high incidence of upper gastrointestinal bleeding in high-risk patients. A previous history of gastrointestinal bleeding appears to be a predictor of adverse gastrointestinal events.

    Notes: The proportion of duodenal ulcers not associated with Helicobacter pylori infection or the use of non-steroidal anti-inflammatory drugs (NSAIDs) is increasing.〈section xml:id="abs1-2"〉〈title type="main"〉Aim:To identify the clinical and endoscopic characteristics of non-H. pylori, non-NSAID duodenal ulcers.〈section xml:id="abs1-3"〉〈title type="main"〉Methods:Clinical and endoscopic data and H. pylori status were prospectively collected from consecutive patients who underwent upper endoscopy from 1997 to 1999. Patients with duodenal ulcers were identified, and those with non-H. pylori, non-NSAID duodenal ulcers were analysed further.〈section xml:id="abs1-4"〉〈title type="main"〉Results:A total of 11 717 upper endoscopies were performed in 8344 patients. Of these, 1153 (14%) had duodenal ulcers. Of 599 patients with active ulcers and known H. pylori status, 104 (17%) had ulcers not associated with H. pylori or the use of NSAIDs, 393 (66%) had ulcers associated with H. pylori alone, 51 (8.5%) had ulcers associated with the use of NSAIDs alone and 51 (8.5%) had ulcers associated with both. Multivariate logistic regression analysis revealed that the presence of concomitant diseases (odds ratio=15.0; 95% confidence interval, 8.64–25.9; P 〈 0.001) and the absence of epigastric pain/discomfort (odds ratio=0.52; 95% confidence interval, 0.29–0.91; P=0.022) were independent predictors for non-H. pylori, non-NSAID duodenal ulcers.〈section xml:id="abs1-5"〉〈title type="main"〉Conclusions:Non-H. pylori, non-NSAID duodenal ulcers exhibit certain distinct clinical and endoscopic characteristics. The presence of concomitant diseases is an important predictive factor.

    Notes: Aim : Pyogenic liver abscesses result in substantial morbidity and mortality. Antimicrobial regimens using sequential intravenous/oral therapy may reduce the length of hospital stay. In this retrospective analysis, the efficacy of continuous intravenous antibiotic therapy (group I) vs. sequential intravenous/oral antibiotic therapy (group II) was studied in patients with pyogenic liver abscess.Methods : One hundred and twelve consecutive patients (55 in group I and 57 in group II) with pyogenic liver abscess were analysed. Clinical response, length of hospital stay and relapse rates were examined.Results : Group II had a significantly shorter duration of intravenous antibiotic treatment (3.2 weeks vs. 5.9 weeks, P 〈 0.01) and a shorter length of hospital stay (28 days vs. 42 days, P 〈 0.01) when compared to group I. Oral antibiotics were prescribed for a median duration of 2.9 weeks in group II after discharge. No relapse occurred within 6 weeks after the completion of treatment in both groups. The cost of therapy was significantly lower in group II than in group I by 33%.Conclusions : A sequential intravenous/oral antibiotic regime is a safe and effective treatment for pyogenic liver abscess. This reduces the cost of therapy and the length of hospital stay.
