Thirty-one normal children, aged 6--18 yr, were studied by measurements of static lung volumes, static expiratory pressure-volume (PV) curves, and maximum expiratory flow-volume (MEFV) curves. A theoretical standard volume was used to compare children of differing size and this showed that total lung capacity (TLC) is also a valid standard volume. The shape(More)
Five patients in a pediatric population were identified with idiopathic follicular bronchitis (IFB) by open lung biopsy and their case records were reviewed. All were tachypneic and had a chronic cough by 6 weeks of age. The physical examination was characterized by diffuse fine crackles in four patients and by coarse rhonchi in one. The chest radiographs(More)
OBJECTIVE To determine whether physiological severity of asthma is associated with increased psychological symptoms in children. METHOD Participants were 337 children, aged 7 to 19 years (mean 11.9, SE 0.13), and a parent of each child. Children's asthma severity was rated by experienced pediatric asthma specialists using current guidelines from the(More)
Pulmonary function was measured in 18 children aged 6 to 9 years who had been born prematurely (mean birth weight 1760 +/- 555 g) and who had each received greater than 100 hours (mean 177 +/- 74 hours) of mechanical ventilation for respiratory distress syndrome (RDS). We used as controls 26 children aged 6 to 7 years who had been born prematurely (mean(More)
Noninvasive exercise testing was used to assess gas exchange in 13 patients age 6-25 yr who had undergone Fontan procedures for tricuspid atresia, five of whom had preexisting Glenn shunts. The results were compared to 28 age- and sex-matched controls. Oxygen saturation was measured by ear oximetry at rest and after exercise. Ventilation, oxygen consumption(More)
The cardiorespiratory response to exercise was examined in 13 patients, 12 to 22 yr of age, who were in stable condition while receiving regular transfusions for thalassemia major. Before transfusion (Hgb, 10.8 g/dl), the patients had reduced peak oxygen consumption for body weight (by 25%, p less than 0.002) in comparison with 20 age- and sex-matched(More)
To identify factors that bring about maturation of the respiratory system, we studied pulmonary function in 18 patients 9 to 19 yr of age with severe growth retardation caused by hypopituitarism. In 6 we measured pulmonary pressure-volume (P-V) curves before and after a 4 to 6 yr period of human growth-hormone-induced catch-up growth. Even when(More)
The objective of this study was to determine patterns of pulmonary function abnormalities and to evaluate how adequately peak flow monitoring was correlated to other spirometric indices in childhood asthma. Ninety-one children, aged 8-15 years, with moderate-to-severe asthma were repeatedly tested in a summer camp. On-site medical staff permitted(More)
The benefit of beta-adrenergic agonists in the treatment of acutely wheezing infants and young children has not been well documented in the outpatient setting. To determine the efficacy of nebulized metaproterenol sulfate, 74 children aged 36 months or younger with acute wheezing participated in a double-masked, randomized, placebo-controlled clinical(More)
