Attitudes towards resuscitation can be discussed with COPD patients by RNS without causing distress. Attitudes to resuscitation could not be predicted from parameters of respiratory disease severity or age.
Primary extraskeletal epithelial neoplasms with osteoclast-like giant cells are rare. We describe a case of renal cell carcinoma with a sarcomatoid component and non-neoplastic osteoclast-like giant cells. The giant cells were noted in both the conventional and the sarcomatoid components of the neoplasm. Immunohistochemical studies indicate that these cells are monocyte/histiocyte in origin and most probably a host stromal reaction to the neoplasm.
The combination of cytological and histological techniques has significantly increased the accuracy of fibreoptic bronchoscopy (FOB) in the diagnosis of lung cancer. We tested the hypothesis that cytological examination of material obtained from the whole endobronchial brush might increase the diagnostic yield in patients where conventional brush specimens were negative. Fifty patients who had undergone FOB for suspected lung cancer were studied prospectively. Bronchial lavage, bronchial biopsy and conventional brushing were performed. The whole endobronchial brush was then cut off the end of its wire and transported in a universal pot containing Shandon cytospin collection fluid. The material was dislodged from the whole brush using a vortex and the remaining fluid was centrifuged at 2,000 r.p.m. The fluid concentrate was used to maketwo cytopsin preparations. Papanicolaou stain was used. Fifty patients were studied, of which thirty-nine (78%) had endoscopicaly visible tumour. Of those, bronchial biopsy conventional brushing lavage and whole brush were positive for malignant cells in 31 (79.4%), 29 (74.3%), 21 (53.8%), and 16 (41%) of cases, respectively. A diagnosis of lung cancer was confirmed in 35 (89.7%) cases of endoscopicaly visible tumour. Conventional brushing was positive in two out of 11 (18.2%) cases with no visible tumour. Whole brush analysis was not positive in any of the cases with negative conventional brushings and was the least sensitive test in detecting malignancy Whole endobronchial brush analysis has no advantage in bronchoscopic diagnosis of patients with suspected lung cancer.
This report describes two cases of segmental pulmonary vein occlusion secondary to lung malignancy in which lung biopsies showed histological features of veno-occlusive disease. These are the first cases to be reported in the literature in which such lung parenchymal histological changes are described in association with lung malignancy.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
