Aim. To develop a method for determining the lung inflation by indexes of forced expiratory flowvolume spirometry. Materials and methods. In 43 patients with mild persistent uncontrolled asthma in combination osmotic airway hyperresponsiveness, function were assessed spirometry using bronchodilation test bodyplethysmography. Results. From entire set parameters, regression analysis, two equatio...
On the assumption that short term changes in lung function may reflect the potential for a long term decline the evolution of lung function indices in 25 steelworkers from a strandcasting department and in 11 comparable steelworkers not exposed to dust was investigated over an almost uninterrupted 21 day working period and over three different workshifts. The mean total dust level in the strand...
background: respiratory diseases cause a considerable amount of morbidity and mortality in the world. pulmonary function tests are important measures for the diagnosis and management of respiratory disorders. workers in tile and ceramic industry are exposed to high amounts of respiratory pollutants. objective: to identify the changes in spirometric parameters in a 2-year period among tile and c...
OBJECTIVES For the purpose of evaluation of exhaled NO as an index of airway inflammation, we assessed changes in fractional exhaled NO (FeNO) across a work shift and its relationship with respiratory complaints. MATERIAL AND METHODS Chronic and work-aggravated respiratory complaints were assessed using a questionnaire in 89 male textile workers. FeNO and spirometry were performed before and ...
A study was performed to determine whether prediction equations issued by the European Community for Steel and Coal (ECSC) and the European Respiratory Society (ERS) fit spirometric data in young adult males. The study comprised 246 randomly selected Dutch conscripts, who participated in the study on the basis of informed consent. A questionnaire was used to assess respiratory symptoms and smok...
BACKGROUND We sought to determine torso injury rates and sensitivities associated with fluid-positive abdominal ultrasound, metabolic acidosis (increased base deficit and lactate), and impaired pulmonary physiology (decreased spirometric volume and PaO2/FiO2). METHODS Level I trauma center prospective pilot and post-pilot study (2000-2001) of stable patients. Increased base deficit was < 0.0 ...
BACKGROUND Current published guidelines on spirometry interpretation suggest an elevated FVC and FEV(1) > 100% of predicted with an obstructive ratio may represent a physiological variant. There is minimal evidence whether this finding can be indicative of symptomatic airways obstruction. METHODS Pulmonary function testing databases for a 4-year period were retrospectively reviewed. All tech...
Fifty-nine children with well-controlled, mild to moderate persistent asthma were studied for the presence and load of torquetenovirus (TTV) in nasal fluid. Rates of TTV positivity and mean nasal TTV loads were not dissimilar to those observed in the general population and in a group of 30 age- and residence-matched healthy control children without a history of asthmatic disease. However, in th...
