  • group a streptococcal paronychia and Blistering Distal Dactylitis in children diagnostic accuracy of a rapid diagnostic test and efficacy of antibiotic treatment
    Journal of the Pediatric Infectious Diseases Society, 2019
    Co-Authors: Camille Jung, Ph Bidet, C Levy, S Bonacorsi, Jamil Amhis, Vincent Salabi, Berkani Nacera, Rahmani Samia, Said Aberrane, R Cohen

    Abstract:

    : Among 174 children with Blistering Distal Dactylitis or paronychia, 36.2% had a positive group A Streptococcus (GAS) rapid detection antigen. For GAS, the outcome for patients who received amoxicillin was favorable in all cases without any surgical procedures; 44.6% of cases due to Staphylococcus aureus infection (38.7%) required surgery.

  • Diagnostic of group A streptococcal Blistering Distal Dactylitis
    Archives de pediatrie : organe officiel de la Societe francaise de pediatrie, 2014
    Co-Authors: R Cohen, C Levy, J Cohen, F Corrard, P Deberdt, S Béchet, S Bonacorsi, Ph Bidet

    Abstract:

    Blistering Distal Dactylitis is a distinct clinical entity, generally due to S. pyogenes, unfrequently reported. Characteristically, Blistering Distal Dactylitis is described as a localized infection involving the Distal phalanx of the digits, and it usually presents as a fluid-filled blister. Between October 2009 and June 2014, 69 children (median age: 60 months, extremes: 0,6-176) were enrolled. The sensitivity of GAS rapid antigen detection test was 97 % (CI 95 %: 83-100 %), the specificity was 76 % (CI 95 %: 60-89 %), the negative predictive value was 97 % (CI 95 %: 83-100 %), and the positive predictive value 76 % (CI 95 %: 60-89 %). All patients with a positive GAS rapid antigen test were treated with antibiotics (amoxicillin essentially) and cured without surgery.

  • Use of group A streptococcal rapid diagnostic test in extra-pharyngeal infections
    Archives de pediatrie : organe officiel de la Societe francaise de pediatrie, 2014
    Co-Authors: A Wollner, Ph Bidet, C Levy, J Cohen, S Béchet, S Bonacorsi, M Benani, F Thollot, R Cohen

    Abstract:

    The purpose of this study was to assess the performances of the group A streptococcus (GAS) rapid antigen diagnostic tests (RADTs) in extra-pharyngeal infections. Between October 2009 and June 2014, 368 patients (median age: 48 months) were enrolled. The pathologies involved were : 160 perineal infections (44 %), 69 Blistering Distal Dactylitis (19 %), 55 cervical lymphadenitis (15 %), 31 crusty or bleeding rhinitis (8 %), and 53 other diseases (14 %). The sensitivity of GAS-RADT used was 96 % (95 % CI: 92-99 %), the specificity 81 % (95 % CI: 75- 86 %), the negative predictive value 97 % (CI 95 %: 93-99 %), and the positive predictive value 79 % (95 % CI: 73-85 %). Finally, positive and negative likelihood ratio were 5 (95 % CI: 4-7) and 0.05 (95 % CI: 0.02-0.11) respectively. The GAS-RADTs developed for pharyngitis have comparable performances in these settings and therefore can be used.
