The optimal strategy for monitoring cystic fibrosis lung disease in infancy remains unclear. Our objective was to describe longitudinal associations between infant pulmonary function tests, chest radiograph scores and other characteristics. Cystic fibrosis patients aged ≤24 months were enrolled in a 10-centre study evaluating infant pulmonary function tests four times over a year. Chest radiogr...

BACKGROUND Ipe is a resistant hardwood that contains naphtoquinones. It is easily found and frequently used in South and Central America. Naphtoquinones are skin sensitizers. OBJECTIVE To describe a case of occupational asthma related to Ipe wood dust. METHODS The patient was submitted to a clinical evaluation consisting of a respiratory symptom questionnaire, occupational history, serial m...

Wheezing during infancy has been linked to early loss of pulmonary function. We prospectively investigated the relation between bronchial hyperresponsiveness (BHR) and progressive impairment of pulmonary function in a cohort of asthmatic infants followed until age 9 years. We studied 129 infants who had had at least three episodes of wheezing. Physical examinations, baseline lung function tests...

OBJECTIVE To determine whether intermittent positive-pressure breathing (IPPB) improved lung compliance, work of breathing, and respiratory function in patients with recent high spinal cord injury (SCI). DESIGN An unblinded randomized crossover trial. SETTING Rehabilitation hospital. PARTICIPANTS Patients (N=14) with SCI caused by trauma within the last 6 months and located between C5 and...

PURPOSE To test quantitative functional lung MRI techniques in young adults with cystic fibrosis (CF) compared to healthy volunteers and to monitor immediate treatment effects of a single inhalation of hypertonic saline in comparison to clinical routine pulmonary function tests. MATERIALS AND METHODS Sixteen clinically stable CF patients and 12 healthy volunteers prospectively underwent two f...

conclusions any discrepancy between histopathologic changes in time-zero biopsies and pattern of early liver laboratory alterations may be considered as a warning for causes other than pri. objectives the aim of this study was to show the correlation between histopathologic changes of pri and the alterations in liver tests in the early post-transplantation period. materials and methods between ...

background: galvanization is the process of coating steel or cast iron pieces with a thin layer of zinc allowing protection against corrosion. one of the important hazards in this industry is exposure to zinc compounds specially zinc oxide fumes and dusts. in this study we evaluated chronic effects of zinc oxide on the respiratory tract of galvanizers. method : 188 workers were selected from a ...

Pulmonary function testing (PFT) is used extensively by pulmonary specialists to address two common clinical questions: (1) What is the risk of a postoperative pulmonary complication in an individual with lung disease? and (2) Will the patient be able to tolerate lung resection surgery? Today, there are numerous tests available to measure pulmonary function; making judicious use of these tests ...
