Bronchial collapse due to bronchomalacia is an important cause of chronic coughing in dogs. Radiographic and CT evidence of bronchial collapse has previously been reported in healthy Beagle dogs under forced expiration. However, published studies in brachycephalic dog breeds that are prone to bronchial collapse are currently lacking. In the present prospective analytical experimental study, CT and radiography were used to measure the bronchial diameter and collapsibility of each pulmonary bronchus during end‐expiratory, 5 mL/kg forced‐expiratory, and 10 mL/kg forced‐expiratory phases in 17 asymptomatic brachycephalic dogs and six healthy Beagle dogs. Bronchial collapsibility was significantly greater during forced expiration, than that at the end of expiration in both groups (P < .001). Bronchial collapsibility measurements of the left lung lobes and the right cranial, middle, and accessory lobes were significantly higher in asymptomatic brachycephalic dogs than those in healthy Beagle dogs, during all expiratory phases (P < .05). The higher bronchial collapsibility of brachycephalic dogs was also supported using CT multiplanar reconstruction images and radiography. In conclusion, radiographic and CT measures of bronchial collapsibility in asymptomatic brachycephalic dogs are higher than measures in healthy Beagle dogs. Therefore, measures of bronchial collapse in brachycephalic dogs should not be evaluated using the same baseline measures as those used for healthy Beagle dogs. 相似文献

Retrospective analysis of factors affecting clinical outcome following CHOP‐based chemotherapy in dogs with primary nodal diffuse large B‐cell lymphoma 下载免费PDF全文
Numerous factors are known to affect the prognosis of dogs with chemotherapy‐treated lymphomas. However, prognostic factors for dogs with specific subtypes of lymphoma are less clearly defined. The objective of this study was to identify prognostic factors for dogs receiving CHOP‐based chemotherapy for primary nodal diffuse large B‐cell lymphoma (DLBCL). Medical records of dogs treated for DLBCL at the Purdue Veterinary Teaching Hospital (PUVTH) from 2006 to 2016 were reviewed. Factors potentially related to prognosis were analysed using multivariable statistical methods. Ninety‐eight dogs were included in the study. Best overall response to chemotherapy was complete remission in 80 dogs (81.6%) and partial remission in 18 dogs (18.4%). Median progression‐free survival (PFS) for the entire population was 252 days (range 19‐1068). Factors significantly associated with achieving partial (rather than complete) remission following CHOP included presence of thrombocytopenia at diagnosis (OR 6.88; 95% CI 1.98‐23.93; P = .002), baseline serum globulin concentration (OR 2.63; 95% CI 1.03‐6.75; P = .044), and age at diagnosis (OR 1.36; 95% CI 1.08‐1.71; P = .009). Factors significantly associated with PFS in the lowest quartile (≤93 days) included presence of thrombocytopenia at diagnosis (OR 8.72; 95% CI 1.54‐49.33; P = .014), age at diagnosis (OR 1.47; 95% CI 1.12‐1.94; P = .005), and baseline neutrophil count (OR 1.18; 95% CI 1.02‐1.37; P = .025). Presence of thrombocytopenia, greater age, higher neutrophil count, and higher serum globulin concentration all may be associated with a particularly poor outcome in dogs receiving CHOP‐based chemotherapy for DLBCL. 相似文献
