Comparison of the ventilating and injection bronchoscopes.

Carcinoma of the lung, stage III. Experience with the new TNM-AJCC classification.
1988
The records of 228 patients who underwent surgery for primary lung cancer in 1970–1986 were reviewed. In 115 cases (94 men, 21 women) the disease was in stage III according to the 1978 classification of the American Joint Committee on Cancer (AJCC). These 115 cases were retrospectively reassessed, using a recently proposed new TNM classification with subdivision of stage III into IIIa, in which the patients may benefit from surgery, and IIIb, in which surgery is not advisable. Stage IIIa disease was present at operation in 87 cases and stage IIIb in 28. Actuarial analysis of survival rates showed that the new subclassification permits identification of those stage III patients who may benef…
Successful treatment of a patient with ARDS after pneumonectomy using high-frequency oscillatory ventilation.
1999
High frequency oscillatory ventilation (HFOV) was used in a patient who developed the acute respiratory distress syndrome 5 days following a right pneumonectomy for bronchogenic carcinoma. When conventional pressure-controlled ventilation failed to maintain adequate oxygenation, HFOV dramatically improved oxygenation within the first few hours of therapy. Pulmonary function and gas exchange recovered during a 10-day period of HFOV. No negative side effects were observed. Early use of HFOV may be a beneficial ventilation strategy for adults with acute pulmonary failure, even in the postoperative period after lung resection.
Hsp60 and Hsp10 down-regulation predicts bronchial epithelial carcinogenesis in smokers with chronic obstructive pulmonary disease.
2006
BACKGROUND. The relation between smoking, chronic obstructive pulmonary disease (COPD), and lung cancer (LC) is an open field of investigation. A higher frequency of adenocarcinoma has been reported in patients with COPD. Heat shock proteins (Hsps) are implicated in tumoral cell growth and differentiation. The aim of the present study was to investigate the expression of Hsp60 and Hsp10 in bronchial biopsies from smokers with COPD and in 10 lung cancer patients and to evaluate the association between Hsps expression and carcinogenetic steps of LC. METHODS. An immunohistochemical study was performed for Hsp60 and Hsp10 in bronchial biopsies from 35 COPD (postbronchodilator forced expiratory …
Induction of accessory cell function of human alveolar macrophages by inhalation of human natural interleukin-2.
1996
Accessory function allows antigen-presenting cells to produce sufficient secondary signals for optimum T cell proliferation and interleukin-2 (IL-2) production. Alveolar macrophages are inferior accessory cells compared to monocytes (PBM). We report here that the accessory index (AI) of alveolar macrophages and PBM of patients with lung metastases of solid tumors treated with inhalations of human natural IL-2 (hnIL-2) increased following its administration (P0.005). The accessory index was significantly elevated from baseline values after 2 weeks of inhalation of 300,000 IU hnIL-2/day (8.2 +/- 10.2 compared to 1.1 +/- 1; P0.001). The inhalation of 150,000 IU also induced increases in the in…
Contrast-enhanced MRI of the lung
2000
The lung has long been neglected by MR imaging. This is due to unique intrinsic difficulties: (1) signal loss due to cardiac pulsation and respiration; (2) susceptibility artifacts caused by multiple air-tissue interfaces; (3) low proton density. There are many MR strategies to overcome these problems. They consist of breath-hold imaging, respiratory and cardiac gating procedures, use of short repetition and echo times, increase of the relaxivity of existing spins by administration of intravenous contrast agents, and enrichment of spin density by hyperpolarized noble gases or oxygen. Improvements in scanner performance and frequent use of contrast media have increased the interest in MR ima…
