Exercise testing was performed on 37 patients with resectable lung lesions who were deemed inoperable because of any of the following risk factors: (1) FEV1 less than or equal to 40 percent of predicted; (2) radionuclide calculated postlobectomy FEV1 less than or equal to 33 percent of predicted; or (3) arterial PCO2 greater than or equal to 45 mm Hg. The(More)
We performed flexible fiberoptic bronchoscopy (FFB) on 106 heavy cigarette smokers. Six bronchial biopsy specimens, obtained from the carina and five major bronchi, were screened for squamous metaplasia. Individual biopsy specimens were sectioned into 4-microns sections, and a metaplasia index (MI), or percentage of sections containing squamous metaplasia,(More)
PURPOSE Retinoids have proven chemopreventive efficacy in both preclinical and clinical studies. This trial was designed to confirm the finding of an earlier uncontrolled trial that the synthetic retinoid etretinate had major activity in reversing squamous metaplasia found in the bronchial epithelium of chronic smokers. PATIENTS AND METHODS We(More)
RATIONALE IgE antibodies to the mammalian oligosaccharide galactose-α-1,3-galactose (α-gal) are common in the southeastern United States. These antibodies, which are induced by ectoparasitic ticks, can give rise to positive skin tests or serum assays with cat extract. OBJECTIVES To evaluate the relationship between IgE antibodies to α-gal and asthma, and(More)
A 64-year-old woman with ovarian carcinoma that had been treated with high-dose chemotherapy and autologous bone marrow transplantation presented with a maculopapular rash on the extremities and miliary infiltrates evident on chest roentgenogram. Transbronchial biopsy specimens revealed caseating granulomas, and cultures grew Mycobacterium terrae. Six weeks(More)
BACKGROUND Harmonia axyridis, the Asian ladybug (ALB), was repeatedly introduced between 1916 and 1990. These beetles are intolerant to cold and move indoors during the winter. OBJECTIVE To investigate sensitization to ALB. METHODS Proteins in ALB extracts were purified by gel filtration and ion exchange chromatography. Purified fractions were screened(More)
Expired nitric oxide (eNO) is a marker of airway inflammation that is increased in asthma. The present study was undertaken to examine the clinical utility of eNO as an aid in the assessment of asthma in the emergency department (ED). Fifty-two adult patients with acute asthma, 53 age- and sex-matched controls, and eight patients with stable asthma were(More)
BACKGROUND Positive skin tests to allergens derived from mouse urine have been reported among patients with asthma. Very few data are available detailing the titer of IgE Ab to mouse allergen and how it varies by location and population. OBJECTIVE To evaluate further the prevalence and titer of IgE Ab to mouse-derived allergens and their relevance to(More)
Bronchial micronuclei, small fragments of extra-nuclear DNA formed during cell division, provide a non-specific but quantifiable marker of DNA damage. Micronuclei have been used to assess carcinogen exposure and as an intermediate endpoint in chemoprevention trials. As part of an ongoing chemoprevention trial, heavy smokers underwent screening bronchoscopy,(More)
