Airway collapse (AC) in dogs includes a tracheal collapse, mainstem and lobar bronchial collapse, and bronchomalacia (i.e., segmental/subsegmental bronchial collapse). The clinical presentation of AC may overlap with non-collapsible airway disease (NCAD) or another non-lower airway respiratory disease (NLARD). This study determined whether paired inspiratory (I)/expiratory (E)-breath-hold computed tomography (I/E-BH CT) can detect a static and dynamic AC in dogs with spontaneous respiratory disease and it compared the CT-derived metrics of the AC to the tracheobronchoscopy metrics. The CT-acquired I and E diameter and cross-sectional area (CSA) for the trachea, mainstem and lobar bronchi in dogs with an AC (n = 16), NCAD (16), and NLARD (19) served for a dynamic percent of the airway narrowing (%AN) calculation. A scoring system assessed the bronchomalacia. The circularity was calculated for each airway. The results were compared to the tracheobronchoscopy collapse grading. In the dogs with an AC, the %AN was larger for the trachea, right mainstem bronchus and right middle lobar bronchus when they were compared to the dogs with NCAD and NLARD. Flattening was only identified for the trachea of the AC dogs. The agreement between the CT and tracheobronchoscopy scores was 20% from trachea to the lobar bronchi and 47% for the segmental/subsegmental bronchi. Paired I/E-BH CT can detect static and dynamic AC with limited agreement with the tracheobronchoscopy metrics. Independent scoring systems that are tailored to the clinical manifestations of functional impairments are needed.
La femme enceinte appréhende de nouveaux ressentis, un corps à l’apparence nouvelle et au rôle contenant. À la confrontation avec un corps étrange s’ajoute la problématisation du corps étranger en soi. Cette métamorphose de la femme en mère implique un jeu d’identifications, identification à l’être en devenir, et identification à la mère. L’ordre des générations est aussi bouleversé : la femme s’ancre dans sa famille non plus seulement en fille mais également en mère. Or, des enfants adoptés à l’international apprennent à se construire avec un corps identique, mais au sein d’une nouvelle culture, d’une nouvelle famille et selon une nouvelle filiation. La grossesse serait donc susceptible de fragiliser des femmes qui ont été adoptées des années auparavant. Suite à des entretiens et des constructions d’arbre généalogique avec sept femmes ayant été adoptées, il semble que devenir mère puisse avoir un retentissement particulier chez des femmes adoptées dans leur enfance.
