PURPOSE To evaluate the incidence of bronchial carcinoid tumor (BCT) in population affected by various lung tumors, retrospectively reviewed between 1986-2001, and to emphasize the radiographic patterns if they are characteristic. MATERIALS AND METHODS In the above mentioned period, chest x-ray and CT were performed in 1110 patients, both male and female,(More)
Chronic obstructive pulmonary disease (COPD) is a serious respiratory pathology characterized by irreversible limitation of expiratory flow and includes chronic obstructive bronchitis, chronic airflow limitation, and emphysema. To determine whether xanthine oxidase activity increased in the airspaces of COPD patients, we examined bronchoalveolar lavage(More)
Xanthine oxidase (xanthine: oxygen oxidoreductase, EC 1.1.3.22), a molybdenum-containing hydroxylase that produces superoxide and uric acid from purine substrates and molecular oxygen, is involved in the oxidative stress underlying several human pathologies including lung diseases. An enzymatic activity similar to xanthine oxidase was previously reported in(More)
The paper describes the preparation and study of the pharmacological properties of a series of derivatives with the general formula. (see article) where R is a cyclohexyl or cyclohexenyl radical and R1 is a hydrogen, methyl or cyclohexyl. The compounds with a single cycloaliphatic radical ortho to the basic chain, and in particular the one with a cyclohexyl(More)
To evaluate the role and the prognostic value of bronchoalveolar lavage (BAL) in scleroderma patients with interstitial lung disease. We reviewed the records of 79 patients with systemic sclerosis (SSc) who had dyspnea and pulmonary involvement and underwent BAL study. Sixty-two patients were prospectively followed up for 12–36 months and re-evaluated by(More)
BACKGROUND Squamous cell carcinoma has a stronger association with tobacco smoking than other non-small cell lung cancers (NSCLC). A study was undertaken to determine whether chronic obstructive pulmonary disease (COPD) is a risk factor for the squamous cell carcinoma histological subtype in smokers with surgically resectable NSCLC. METHODS Using a(More)
BACKGROUND Near-fatal asthma (NFA) is characterized by severe asthma attacks usually requiring intensive care unit admission. This phenotype of asthma has been studied mainly in acute conditions. METHODS The aim of our study was to compare the clinical, functional and inflammatory characteristics of NFA patients with mild to severe asthmatics in stable(More)
The paper describes the synthesis and the pharmacological evaluation of some derivatives of prenylamine, all with a cycloaliphatic ring within or instead of the isopropylamine moiety. Their general formulas are: (C6H5)2CH-CH2-CH2-NH-CH-CH2-R CH2 (I) (C6H5)2CH-CH2-CH2-NH-R' (II) where R contains and R' is a cycloaliphatic ring. Several compounds and(More)
BACKGROUND Reactive oxygen radicals are involved in many respiratory diseases, including chronic obstructive pulmonary disease (COPD). Carbocysteine lysine salt monohydrate (CLS) is a mucoactive drug effective in the treatment of bronchopulmonary diseases characterized by mucus alterations, including COPD. In the present study, the antioxidant activity of(More)
We report here a case of primary pulmonary epithelioid hemangioendothelioma diagnosed in a 67-year-old Caucasian man, presenting with exertion dyspnoea, dry cough, and multiple bilateral pulmonary nodules revealed by computed tomography. At the 18F-fluorodeoxyglucose positron emission tomography, these nodules were negative. The histopathological diagnosis(More)
