Abstract

We appreciate Dr Weinberger's comments, and we are aware of his prior contributions to the exercise-induced dyspnea literature. [1] Abu-Hasan M. Tannous B. Weiberger M. Exercise-induced dyspnea in children and adolescents: if not asthma then what?. Ann Allergy Asthma Immunol. 2005; 94: 366-371 Abstract Full Text PDF PubMed Scopus (162) Google Scholar We completely agree with the title of his correspondence, [2] Weinberger M. Exercise-induced dyspnea that is not from asthma is more than vocal cord dysfunction or laryngomalacia. Ann Allergy Asthma Immunol. 2014; (in press) PubMed Google Scholar and in fact we have previously published a retrospective case description entitled “Masqueraders of Exercise-Induced Vocal Cord Dysfunction.” [3] Tilles S.A. Inglis A.F. Masqueraders of exercise-induced vocal cord dysfunction. J Allergy Clin Immunol. 2009; 124: 377-378 Abstract Full Text Full Text PDF PubMed Scopus (15) Google Scholar We also agree that it is unfortunate that in our current study we were not able to include the total number of children examined with our exercise protocol, but our goal was not to present a cross-section of all of the patients referred to our clinic. Rather, our study focused only on patients with documented paradoxical laryngeal motion during symptoms provoked by free running exercise challenge. We believe that this group of patients may include a common dominant phenotype. Exercise-induced dyspnea: more than vocal cord dysfunction or laryngomalaciaAnnals of Allergy, Asthma & ImmunologyVol. 112Issue 3PreviewThe report by Tiles et al1 describes identification of 83 children and adolescents with exercise-induced vocal cord dysfunction (EIVCD) and 60 with exercise-induced laryngomalacia (EIL). Unfortunately, the authors do not indicate how many children were examined using the free-running protocol described to find 143 children with those disorders. However, the number of patients they describe with those disorders is inconsistent with physiologic abnormalities associated with exercise-induced dyspnea that we previously reported. Full-Text PDF
