Specific cell typing in lung cancer has important implications for assessment of prognosis and the planning of treatment. Cell typing is, however, often difficult and the problem has been compounded by the universal use of the flexible fibreoptic bronchoscope, which yields specimens only 2 mm in diameter. We have reviewed the records of 107 patients who had(More)
To determine whether occupational exposure to vinyl chloride gas and polyvinyl chloride dust is associated with changes in pulmonary function, spirometry and maximum expiratory flow-volume curves were obtained in 348 workers in a VC polymerization plant. The major finding was diminution in air flow in 200 workers (57.5 percent). This abnormality correlated(More)
A 46-year-old man with diabetes mellitus and cadaveric kidney transplant, maintained on a regimen of prednisone and azathioprine, developed a necrotizing pneumonia. The abscess cavity became secondarily infected with Rhizopus and was cured by surgical resection. Secondary invasion of an abscess cavity by Rhizopus and the successful surgical treatment of(More)
Expression of major histocompatibility complex (MHC) class II antigens is a requirement for accessory cell function in antigen presentation. Recent reports have demonstrated the presence of class II antigens on human bronchial epithelial cells. In the present study, immunohistochemical staining revealed HLA-DR on human airway epithelial cells obtained from(More)
Pulmonary function tests in 25 newly studied patients with Stage I and 19 with Stage II sarcoidosis revealed normal mean values in Stage I for all tests except DLCOSB. Mean values for VC, TLC, MMF, and exercise Pao, were abnormal in Stage II and significantly different from Stage I. There was a parallel difference in prevalence of impairment of these(More)
A 41-year-old man presented with an asymptomatic superior mediastinal mass. At thoracotomy, a duplication cyst of the foregut was found. Microscopic examination of the cyst revealed mucosal alterations ranging from dysplasia and in situ carcinoma to infiltrating colonic carcinoma. Although malignant change has been reported in intra-abdominal foregut cysts,(More)
Most physicians fail to recognize Mycobacterium avium-intracellulare (MAI) as a major pathogen for pulmonary disease among patients admitted to hospitals throughout the United States. In a review of all records of positive MAI cultures during the 10 years beginning July 1, 1979, at The Mount Sinai Hospital, New York City, we have identified 244 patients who(More)
