Tracheobronchopathia osteochondroplastica (TO) is a rare benign disease characterized by the presence of osseous and cartilaginous submucosal nodules projecting into the tracheobronchial tree. Most cases are asymptomatic and discovered incidentally at post‐mortem. We identified a case of TO on thoracic spiral CT and confirmed the diagnosis on bronchoscopy. This article reviews the imaging characteristics of TO, and shows the 3‐D virtual bronchoscopic and multiplanar reconstruction appearances of TO. 相似文献

The present study compared the accuracy of ventilation perfusion scintigraphy (VQS) and CT pulmonary angiography (CTPA) for the diagnosis of pulmonary embolism. This was a prospective observational study of 112 patients with suspected pulmonary embolism (PE) who could be studied with both investigations within 24 h. Results were compared to final diagnosis at completion of 6-month follow up, using receiver operating characteristic (ROC) analysis. Pulmonary embolism was diagnosed in 27 referred patients (24%). The sensitivity and specificity of VQS and CTPA were similar to that reported from the literature. A normal VQ scan had the highest negative predictive value (100%), while a high-probability VQ scan had the highest positive predictive value (92%). There was no overall difference (area under the ROC curve (AUC)) between VQS (AUC (95% CI) = 0.82 (0.75,0.89)) and CTPA (AUC = 0.88 (0.81,0.94)) for the diagnosis of PE. Among patients with abnormal chest X-rays, CTPA (AUC 0.90 (0.83,0.97)) appeared somewhat better than VQS (AUC 0.78 (0.68,0.88)) but this difference did not reach statistical significance. In this instance, CTPA is at least as accurate as VQS and may provide an opportunity to make alternative diagnoses. 相似文献

Who can give ‘spiritual care’? The management of spiritually sensitive interactions between nurses and patients Aims This article considers the purpose of contemporary ‘spiritual care’ in order to help managers make informed decisions about its appropriate delivery in a clinical context. Background Although there are national policies in place concerning spiritual care, surveys indicate that nurses are reluctant to engage with the spiritual needs of patients. Evaluation A consideration of the character of spiritual care indicates the need to take account of the context of contemporary Western society. A model drawn from the social psychology of religion is used to analyse the different types of nurse–patient interaction available in the provision of spiritual care. Key Issues Although religious and spiritual commitments can vary widely, they are subject to the same pressures in a secular and pluralist social context. This enables some general guidelines to be developed. Conclusions Effective spiritual care requires a consideration of both the patient’s and the nurse’s implicit and explicit religious commitments. Implications for nursing management Nurse managers need to take account of the personal commitments of nurses when directing them to offer spiritual care. This article offers a diagnostic tool for deploying nurses in an appropriate way. 相似文献
