Histopathologic changes are not specific for diagnosis of gastric antral vascular ectasia (GAVE) syndrome - A review of the pathogenesis and a comparative image analysis morphometric study of GAVE syndrome and gastric hyperplastic polyps

We studied the nonspecific nature of the histologic findings in the gastric antral vascular ectasia (GAVE) syndrome by using a morphometric comparison with common gastric lesions including hyperplastic polyps and gastritis. Five clinicopathologically confirmed cases of GAVE syndrome and 41 cases of gastric hyperplastic polyps were diagnosed during a 5-year interval at Summa Health Systems (Akron, Ohio). These cases, as well as 16 randomly selected cases of nonspecific gastritis and 9 normal gastric antral biopsy specimens, were evaluated. A semiquantitative comparison of the light microscopic findings believed to be essential in diagnosis of GAVE syndrome, including vascular hyperplasia, mucosal vascular ectasia, intravascular fibrin thrombi, and fibromuscular hyperplasia, was performed. Image analysis morphometric measures of the area ratio (vascular area/total biopsy area), mean vascular area, and number of ectatic vessels per square millimeter of tissue were performed on the CAS 200 Image Analyzer (Becton Dickinson, San Jose, Calif). By morphometric and statistical parametric analysis, several histopathologic variables, including area ratio, mean vascular area, mucosal vascular ectasia, and fibromuscular hyperplasia, did not confidently differentiate the histologic features of gastric hyperplastic polyp from those of GAVE syndrome, but did apparently differentiate GAVE syndrome from gastritis and normal gastric mucosa. The propensity of gastric hyperplastic polyps to undergo prolapse changes and prolapse as one proposed mechanism for development of the GAVE syndrome lesion probably accounts for this morphologic similarity. Specific diagnostic histopathologic changes probably do not exist for the GAVE syndrome.

EMERGENCE OF ANTIMICROBIAL RESISTANCE IN GRAM-NEGATIVE BACILLI CAUSING BACTEREMIA DURING THERAPY
beta-lactam antibiotics; cephalosporins; enterobacter-cloacae; Pathology
Treatment of serious infections caused by gram-negative bacilli with beta-lactam antimicrobial agents can induce Class I beta-lactamase production. This phenomenon can result in resistant microorganisms, and has been postulated to be a cause of therapeutic failure. The charts of patients bacteremic with Pseudomonas aeruginosa, Serratia marcescens, Enterobacter cloacae, Citrobacter freundii, Proteus vulgaris, and Providencia species (n=120) during a 3-year period were reviewed to determine how common the emergence of resistance was, and to determine if in vitro susceptibility testing was a reliable therapeutic guide. Emergence of resistance was believed to occur when a subsequent bacteremic isolate showed at least a fourfold increase in minimum inhibitory concentration accompanied by a change of interpretive susceptibility category. In the group of patients who survived at least 48 hours that received beta-lactam therapy (n=76), one case of emergence of resistance was identified (1.3%). Emergence of resistance to beta-lactam antimicrobial agents did not commonly cause therapeutic failure at our institution, and susceptibility testing of gram-negative bacilli by usual methods was a reliable guide to antimicrobial therapy.

Impact of Interventions to Change CBC and Differential Ordering Patterns in the Emergency Department.
Objectives: A CBC with leukocyte differential (CBC-DIFF) is a frequently ordered emergency department (ED) test. The DIFF component often does not add to clinical decision making. Our objective was to evaluate the impact of a performance improvement project on CBC ordering. Methods: ED orders for CBC-DIFF were identified through the laboratory information system. Two interventions were evaluated: an educational intervention regarding CBC-DIFF uses and a reprioritization of ED CBC-DIFF and CBC in the electronic medical record (EMR) orders. Pearson chi2 tests were used to assess for differences in the proportions. Results: There was no difference in the proportion of CBC tests performed after the education intervention (175/6,192, 2.8% [95% CI, 2.39%-3.21%] vs 219/6,270, 3.5% [95% CI, 3.05%-3.95%]). There was a significant increase in CBC samples ordered following the EMR intervention (604/6,044, 9.1% [95% CI, 8.37%-9.83%]; P \textless .01). Conclusions: Reprioritizing EMR laboratory orders can reduce overutilization of CBC-DIFF testing.
