Fifty normophonic women underwent two sessions of voice loading in which the required intensity level of voice varied: 60-65 dB(A) for the first session, and 70-75 dB(A) for the second session. Objective measurements and subjective self-ratings were presented in a previous study (Remacle, Finck, Roche & Morsomme, 2012). Here are the results of perceptual analysis based on comparative judgments. Ten expert listeners evaluated the pressedness and the breathiness of one sentence recorded before and after each loading session. Pairs of stimuli were presented randomly to listeners who were asked to designate the most pressed sample at a first listening and the most breathy sample at a second listening. Each pair of stimuli was presented twice in order to evaluate the reliability. Results indicate that inter-judges and intra-judges reliability was poor to fair. Concerning the duration effect of vocal loading, results showed a significant decrease of breathiness but no change of pressedness after reading in both sessions. The decreased breathiness represents a voice improvement which could be interpreted as an adaptation of voice to loading. When comparing the two intensity levels, no difference was found for breathiness and pressedness after vocal loading. Similarly to objective measurements and self-ratings, perceptual assessments suggest that the duration of vocal loading has more effects on voice than its intensity level.

La prévalence élevée des troubles de la voix chez ces professionnels serait en partie liée aux trois facteurs principaux de charge vocale que sont la durée de phonation, le niveau de pression sonore, et la fréquence vocale. Ces facteurs sont associés à des contraintes mécaniques appliquées aux plis vocaux lors de la vibration, potentiellement responsables de microtraumatismes du tissu, et participant au développement de lésions bénignes. Notre contribution intervient à deux niveaux d’étude de la charge vocale. Dans un premier temps, nous l’avons quantifiée en situation écologique dans une population d’enseignantes, en comparant deux niveaux de l’enseignement ordinaire belge : le maternel et le primaire. A cette fin, le comportement vocal de 12 enseignantes du maternel et de 20 enseignantes du primaire a été enregistré durant une semaine de travail, à l’aide d’un système de dosimétrie. Les objectifs étaient, d’une part, de déterminer les différences d’utilisation vocale selon le niveau d’enseignement, et d’autre part, de comparer l’utilisation vocale professionnelle et extra-professionnelle des enseignantes. Globalement, nos résultats montrent une charge vocale plus élevée en situation professionnelle qu’en situation extra-professionnelle. Par ailleurs, les enseignantes du maternel présentent une charge vocale plus élevée que celles du primaire, en termes de nombre de cycles vibratoires et de distance parcourue par les plis vocaux. Dans un deuxième temps, nous avons étudié l’impact de la charge vocale sur la fonction phonatoire et sur la qualité vocale en condition de laboratoire. Une première condition expérimentale avait pour but d’améliorer la compréhension des facteurs de durée et d’intensité de la charge vocale, en soumettant 50 femmes normophoniques à 2 heures de charge, réalisées à deux reprises en variant le niveau d’intensité. Une seconde condition expérimentale avait pour but de comparer les effets de 2 heures de charge chez 16 enseignantes normophoniques et 16 enseignantes dysphoniques. Les effets de la charge vocale ont été évalués à l’aide de mesures objectives et subjectives. Les principaux résultats montrent plus d’impact de la durée que de l’intensité de la charge sur les paramètres observés. Par ailleurs, peu de différences sont observées entre les deux groupes d’enseignantes au cours de la tâche de charge, suggérant que les enseignantes dysphoniques présentent une bonne résistance durant la charge.

This study compared vocal loading of kindergarten and elementary school teachers; professional and non-professional vocal load was determined for both groups. Method: Twelve kindergarten and twenty elementary school female teachers were monitored during one workweek using the Ambulatory Phonation Monitor, Model 3200 (KayPENTAX). Vocal loading parameters analyzed were phonation time, F0, SPL, distance dose and cycle dose. A total of 160 days (≈1513 hours) of collected data were analyzed. Results and conclusions: All the parameters were higher for kindergarten teachers than for elementary school teachers in both professional and non-professional environments, but the differences were significant only for the cycle dose and the distance dose (p < .05). The higher vocal load measured in kindergarten teachers suggests that they could be more at risk for developing voice disorders than elementary school teachers. Particular attention should be paid to this specific group of teachers working with young children. Concerning the comparisons between professional and non-professional voice use, significant differences were observed for all parameters (p < .0001), indicating that vocal load was higher in the professional environment for both groups.

CX3CR1, the only receptor for fractalkine/CX3CL1, is abundantly expressed by NK cells, and was recently shown to also be a receptor for eotaxin-3/CCL26. However, no reports explored the NK cells-CX3CL1-CCL26 axis via CX3CR1 in allergy. OBJECTIVE: Our goals were first to determine specifically NK cell recruitment pattern in nasal tissue of allergic chronic rhinosinusitis (ACRS) and non-allergic chronic rhinosinusitis (NACRS) patients in comparison with healthy controls, and secondly, to investigate the function of CX3CR1 in NK cell migration. METHODS: Immunohistochemistry, microchemotaxis chambers, flow cytometry and confocal microscopy were used in this study. RESULTS: Herein, we showed that NK cells infiltrated the epithelial layers of nasal tissue only in ACRS patients and not in NACRS patients or controls. NK cells were also more numerous in the stroma of the nasal tissue from ACRS patients compared with NACRS patients or controls. This migration could be mediated by both CX3CL1 and CCL26, as these two chemokines induced NK cell migration. Moreover, both molecules also stimulated cytoskeleton changes and F-actin reorganisation in NK cells. Chemotaxis and cytoskeleton changes were sensitive to genistein, a tyrosine kinase inhibitor. By flow cytometry, we demonstrated that a single antigen nasal provocation challenge increased the expression of CX3CR1 on NK cells in allergic rhinitis (AR) patients. The function of this receptor was associated with a significant augmentation of NK cell chemotaxis against the optimal doses of CX3CL1 and CCL26. CONCLUSIONS AND CLINICAL RELEVANCE: Our results highlight a novel role for CX3CR1 in NK cell migration that may contribute to the NK cell trafficking to the allergic upper airway. This could be mediated largely by CX3CL1 and CCL26 stimulation of the tyrosine kinase pathway. <br/> <br/>Commentary: (c) 2012 Blackwell Publishing Ltd.
