BACKGROUND Allergic disorders are characterized by a systemic involvement of the immune response. There is a clear link between allergic rhinitis and asthma. Bronchial hyperreactivity (BHR) may be present in rhinitics. Smaller airways may also be impaired in mild asthma. This study aimed at evaluating a group of subjects suffering from perennial allergic rhinitis alone to investigate the presen...

Background: Enteral intolerance in premature infants is associated with several morbidities, especially very low birth weight (VLBW). There are only a few dietary practices to provide better outcomes newborns VLBW. This study aimed assess the factors time achieve full enteral feeding (FEF) VLBW.
 Methods: was retrospective on VLBW Neonatology Unit of Sanglah Central General Hospital, Bali ...

BACKGROUND: Total lung capacity (TLC), forced expiratory flow between 25 and 75% (FEF25-75%), peak (PEF), or post-bronchodilator volume response is recommended to detect obstructive abnormalities in the lung. The present study was performed evaluate usefulness of these pulmonary function test (PFT) parameters diagnose disease subjects with a restrictive pattern spirometry. <...

Welding is a process during which fumes, gases, electromagnetic radiation and noise are emitted as by-products. Metal oxide particles are particularly hazardous components of welding fumes. Welding has been found to be associated with respiratory symptoms and our objective in the present study was to study the effects of welding on pulmonary function and serum oxidant-antioxidant status. Fifty-...

Parental tobacco smoking is associated with lower airway function and an increased incidence of wheezy respiratory illnesses in infants. We evaluated in 76 healthy infants whether exposure to parental tobacco smoking was associated with airway hyperreactivity, which could contribute to lower airway function and the increased wheezy illnesses. Airway function was measured using the raised-volume...

BACKGROUND We previously reported that asthmatic children with GSTM1 null genotype may be more susceptible to the acute effect of ozone on the small airways and might benefit from antioxidant supplementation. This study aims to assess the acute effect of ozone on lung function (FEF(25-75)) in asthmatic children according to dietary intake of vitamin C and the number of putative risk alleles in ...

Measuring forced expiratory flows from raised lung volume in infants represents a significant advance in the assessment of pulmonary function early in life. However, variability in the main parameters obtained with raised volume rapid thoracic compression (RVRTC), FVC, FEV(0.5), FEF(50), FEF(75), and FEF(25-75), has not been completely evaluated. This study was performed to determine the intra-...

Exhaled nitric oxide (NO) is altered in asthmatic subjects with exercise-induced bronchoconstriction (EIB). However, the physiological interpretation of exhaled NO is limited because of its dependence on exhalation flow and the inability to distinguish completely proximal (large airway) from peripheral (small airway and alveolar) contributions. We estimated flow-independent NO exchange paramete...

Background While the hereditary component of asthma has been established, its influence on early respiratory function changes in otherwise healthy offspring remains to be explored. Dynamic lung tests assess airflow and out lungs, providing valuable insights into health detecting potential limitations. This study aimed compare dynamic functions between asthmatic non-asthmatic parents. Methodolog...

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...
