Refining The Optimal First Treatment For Pediatric Breast Abscesses, Kayla B. Briggs

Research Days

Background: We previously reported treatment and outcomes of children with untreated, not spontaneously draining (UTND) breast abscesses. What has not been well defined however are those with previously treated, not spontaneously draining (PTND) pediatric breast abscesses. In general, a more conservative approach is favored in children with breast abscesses to avoid damage to the developing breast bud.

Objectives/Goal: We sought to determine if care at a pediatric tertiary referral center impacts disease persistence rate.

Methods/Design: Following IRB approval, patientstherapy.

Results: In all, 114 patients met inclusion criteria, 96 in the UTND group and 18 in the PTND group (Figure 1). …

Early and accurate diagnosis of GAS is important for appropriate antibiotic therapy to prevent GAS sequalae. The Revogene Strep A molecular assay (Meridian Bioscience Canada Inc, Quebec City, QC, Canada) is an automated real-time PCR assay for GAS detection from throat swab specimens within approximately 70 min. This multicenter prospective study evaluated the performance of the Revogene Strep A molecular assay compared to that …

Development Of A Blocking Enzyme-Linked Immunosorbent Assay For Detection Of Serum Antibodies To O157 Antigen Of Escherichia Coli., W Laegreid, M Hoffman, J Keen, R Elder, J Kwang

The O157 antigen of Escherichia coli shares structural elements with lipopolysaccharide (LPS) antigens of other bacterial species, notably Brucella abortus and Yersinia enterocolitica 09, a fact that confounds the interpretation of assays for anti-O157 antibodies. To address this problem, a blocking enzyme-linked immunosorbent assay (bELISA) was designed with E. coli O157:H7 LPS as the antigen and a monoclonal antibody specific for E. coli O157, designated 13B3, as the competing antibody. The bELISA had equivalent sensitivity to, and significantly higher specificity than, the indirect ELISA (iELISA), detecting anti-O157 antibodies in sera from cattle experimentally inoculated with O157:H7. Only 13% of sera …
