ANTIOXIDANT-VITAMIN C: LUNG FUNCTION; LUNG CANCER

Lung function predicts lung cancer.

Recently, we and others have shown that between 50 and 80% of patients diagnosed with lung cancer had pre-existing chronic obstructive pulmonary disease (COPD) [2–4] consistent with the findings of CALABRO et al. [1]. In our series of 446 lung cancer patients, we reported that 60–65% had prebronchodilator Global Initiative for Obstructive Lung Disease (GOLD) 1+ spirometric criteria for COPD [2]...

Dietary vitamin C intake and lung function in rural China.

The relation between dietary vitamin C intake and pulmonary function was investigated in a cross-sectional study carried out in 69 counties in rural China in 1989. Within each of the 69 counties, 120 subjects aged 35-64 years were identified using a three-stage random clustering procedure. Each subject underwent pulmonary function testing, completed a detailed questionnaire, and provided a bloo...

Vitamin D and lung function.

Afzal et al recently reported that low plasma 25-hydroxyvitamin D is associated with a decline in lung function and chronic obstructive pulmonary disease (COPD). While this finding persisted after adjustment for possible confounding variables, and concurs with the findings of others, we believe it might still be spurious. First, we suggest the association between plasma vitamin D and lung funct...

Pulmonary Actinomycosis Mimicking Lung Cancer

Herein, we reported on a case of solid type of pulmonary actinomycosis in a 10-year-old boy. He had productive cough for 40 days. Bronchoscopy was normal. Cmputed tomography revealed a solid large mass in the upper lobe of his left lung with mimicking malignant leisions. He was referred for surgery and underwent left upper lobectomy. Macroscopically, the specimen measured 13×9×5 cm and was crea...
