Bronchial carcinoid tumors account for 1–2% of all primary lung tumors and are separated into 2 subgroups: typical and atypical carcinoids. Atypical carcinoids as intermediategrade malignancies can metastasize more frequently, thus exhibiting poorer prognosis than the low-grade typical carcinoid tumors. Surgical resection remains the mainstay of treatment for pulmonary carcinoids. Bronchoscopic...

Background: Pseudomonas aeruginosa is a cause of infections of the lower respiratory tract among patients with chronic lung disorders. It is questionable whether virulence of this species may be influenced by multidrug resistance (MDR). Objectives: To define the impact of MDR in experimental lung infection. Methods: Experimental empyema was induced in rabbits by MDR (group A, n = 16) and by sus...

A parallel, double-blind, randomized study comparing iohexol and metrizamide-both 180 mg I/ml-in lumbar myelography was carried out in 60 consecutive patients. Eight to 15 ml of contrast medium were administered with the upper level at the middle thoracic column. A detailed neurologic examination was performed before and 24 hr after myelography. EEG recordings-evaluated visually and with fast F...

Background: Acute exacerbation is a substantial cause of death in patients with idiopathic pulmonary fibrosis with poorly described prognostic factors. Objectives: To review the features associated with acute exacerbation of idiopathic pulmonary fibrosis and assess its prognostic factors. Methods: Thirty-seven occurrences of acute exacerbation of idiopathic pulmonary fibrosis were retrospective...

OBJECTIVE To examine the effects of animal-source foods on toddler growth. DESIGN A 5-month comparison feeding intervention study with one of three millet-based porridges randomized to eighteen feeding stations serving 303 children aged 11-40 months. Feeding stations served plain millet porridge (Plain group), porridge with milk (Milk group) or porridge with beef (Meat group). Anthropometry, ...

Background: Few prospective studies have evaluated the role of endobronchial needle aspiration in diagnosing central airways neoplasms. Rapid on-site evaluation has long been used in transbronchial needle aspiration of adenopathies and peripheral lesions, but its role in sampling central malignancies has not been substantiated yet. Objectives: In this study we evaluated if endobronchial needle ...

Background: There have been several attempts to systematically assess performance in bronchoscopy. Earlier validation studies have used bronchoscopy simulators, not real-life performance in patients. Objectives: The aim of this study was to explore the reliability and validity of an assessment tool aimed for the use in a clinical setting. Methods: Five junior residents, 5 senior residents and 9...

Background: Natural surfactant combined with beclomethasone decreases pulmonary oxidative stress in preterm lambs with respiratory distress syndrome (RDS). Objectives: To test the hypothesis that this occurs through a decrease in pulmonary inflammation. Methods: Preterm lambs received 200 mg/kg of natural surfactant or 200 mg/kg of natural surfactant combined with 400 or 800 g/kg of beclomethas...

Ten subjects with normal hemodynamics were studied during elective cardiac catheterization with right and left heart multisensor micromanometry to assess hemodynamic responses to the Mueller maneuver. Simultaneous right and left circulatory hemodynamics and left ventricular, pulmonary arterial, and aortic pressures were recorded, in addition to pulmonary arterial and aortic flow velocities. Ste...
