Effect of leaflets vs. food samples on food purchasing.

Attempts to influence purchases of oranges and whole wheat bread indicated that both leaflets describing the merits of the food and samples provided for testing had some degree of success in stimulating sales. The attempts were more successful for whole wheat bread than for oranges. The sustained effect of the promotions was not measured. Directing attention to specific foods may be an effective method of introducing nutritionally desirable foods into the diet and thus constitute an effective method of nutrition education.

Predicting outcome after appendicectomy.

AIM: To validate an intraoperative appendicitis severity score (IASS) and examine outcome following emergency appendectomy. METHODS: A prospective study was undertaken, enrolling consecutive patients undergoing emergency appendicectomy. Data were obtained independently on preoperative Alvarado scores, IASS (0-3: 0 no inflammation, 1 engorged appendix/no peritonitis, 2 peritoneal reaction/exudate or 3 evidence of perforation/abscess) and postoperative outcome parameters. RESULTS: There were 149 patients identified with a mean age of 20.7 years. There was no association between Alvarado score and length of hospital stay, septic complication, patient sex or duration of symptoms (p>0.05). IASS was found to be an independent risk factor for septic complication, wound infection (p<0.05) and length of hospital stay (p<0.001). There was no correlation between preoperative duration of symptoms or time until surgery and intraoperative score. CONCLUSIONS: This simple scoring system can identify patients more likely to suffer morbidity following emergency appendicectomy. Specifically, this system identifies patients who have a high risk of sepsis and therefore could be of use when comparing healthcare performance.

Gore-Tex prosthetic ligament in anterior cruciate deficient knees.

Reconstruction for symptomatic anterior cruciate deficient knees has yielded varying success rates. Prosthetic cruciate replacement has recently become a potentially attractive alternative. The results of the Gore-Tex polytetrafluoroethylene ligament, which is intended as a permanent replacement, are reported. Eighty-two patients were followed prospectively, mean age was 28 years (range, 16 to 51 years) and mean followup was 18 months (range, 12 to 30 months). Subjective scores improved in all categories, including pain, swelling, giving way, locking, and stair climbing. All patients without complications had no episodes of actual giving way, considered themselves improved, and returned to activities of daily living at 3 weeks and athletics at 8 months. Range of motion lacking at 3 months was 2 degrees of extension and 10 degrees of flexion, and at 12 months was 0 degrees of extension and 4 degrees of flexion. All mean objective data, including the anterior drawer, Lachman, and pivot shift, demonstrated improvement at final followup. Cybex testing revealed improvement in relative quadriceps strength from 88% to 99%. The KT-1000 Arthrometer showed improvement in the injured-normal knee difference score throughout the follow-up period. Of importance is that while final objective data was improved over initial data, an early nonprogressive shift toward loosening was indicated by worsening of the drawer, Lachman, pivot shift, and KT-1000 scores. This shift may be attributed to resorption of interposed soft tissue, creep, or loosening of the graft. Subjective scores remained stable after improving. Complications included four ruptures, four chronic sterile effusions with partial attenuation, one infection, and one symptomatic loose body.(ABSTRACT TRUNCATED AT 250 WORDS)
