PREAMBULE
• Toux chronique de l’enfant:
   –   Symptôme fréquemment rapporté
   –   Retentissement familial et social important
   –   Motif très fréquent de consultation
   –   Sujet historiquement peu exploré
   Ø Prise en charge longtemps basée sur l’application d’algorithmes de prise
     en charge «adulte » appliqués à l’enfant

• Travaux de recherche récents:
   Ø Amélioration des connaissances
      • Mécanismes physiopathologiques de la toux
      • Etiologies pédiatriques (PBB, …)
      • Evolution et morbidité(s) associée(s)
