31 de ago. de 2021 · Abstract. In the 50 years since its inception by Dr. Liebow, the diagnosis of usual interstitial pneumonia (UIP) by pathologists has changed significantly. This manuscript reviews the...
1 de jul. de 2010 · The bronchointerstitial form of interstitial pneumonia is used to describe uncomplicated viral infections of the lung due to BHV-1, PI-3, and BRSV infections.4, 5, 31 Ellis and colleagues 8 also described pulmonary lesions associated with experimental BVDV type 2 infections as bronchointerstitial pneumonia.
Histologically, moderate to severe, necrotizing to pyonecrotizing bronchointerstitial pneumonia was accompanied by serofibrinous exudation and hyaline membranes in the alveolar spaces. Influenza A virus was isolated from nasal secretions of the male and from lung homogenate of the female cat.
31 de ago. de 2021 · This evolution of the diagnostic term UIP has created challenges in the pathologic community and in the application of clinical trial results to clinical practice. This review discusses the evolution of histologic UIP over the years and defines the current state of histologic UIP in 2021.
29 de oct. de 2021 · The presence of bronchointerstitial pneumonia and PCV2 antigen in infiltrating macrophages is indicative that PCV2 plays a role in the etiology of pneumonia [52,53]. In the lung, the PCV2 antigen or genome can be detected mainly in the cytoplasm of macrophages and dendritic cells, but also in monocytes, bronchial epithelial cells ...
6 de mar. de 2022 · Diffuse alveolar damage is one of the more frequently identified histologic types of interstitial pneumonia and involves injury to alveolar epithelial and/or endothelial cells, with 3 distinct stages. The first is the “exudative” stage, with alveolar edema and hyaline membranes.
1 de abr. de 2022 · BRSV infection is known to cause several distinctive histopathological changes, including epithelial syncytia formation and intracytoplasmic viral inclusions. However, distinguishing bovine AIP from BRSV-related pneumonia by clinical presentation, gross pathology or histopathology can sometimes be challenging.
