Background: The increasing global prevalence of obesity poses significant public health problems, as obesity exerts adverse effects on many systems and lung function. However, research on the lung function of preschool children with obesity is limited and inconclusive. In addition, studies specific to obesity indices that influence lung function in young children with obesity are limited.
Purpose: This study aimed... |
Airway pathology in children with atopic asthma can be reflected by the concave shape of the maximal expiratory flow-volume (MEFV) curve and high fractional exhaled nitric oxide (FeNO) values. We evaluated the capacity of the curvilinearity of the MEFV curve, FeNO, and their combination to distinguish subjects with atopic asthma from healthy individuals. FeNO and angle β, which characterizes the general... |
Idiopathic scoliosis is a structural lateral curvature of the spine of unknown etiology. The relationship between degree of spine curvature and cardiopulmonary function has not yet been investigated. The purpose of this study was to determine the association between scoliosis and cardiopulmonary characteristics. Ninety children who underwent preoperative pulmonary or cardiac evaluation at a single spine institution over 41 months were... |
Purpose : The results of pulmonary function test (PFT) in children are variable according to the patient's cooperation and comprehensiveness. This study has intended to figure out the effectiveness of pre-education and training with balloons on PFT in children. Methods : One hundred six children mean aged 9.35?.92 years were tested. All participants performed PFT twice in 30 minutes intervals.... |
Purpose : Asthma is defined as chronic inflammation of the lower small airways, and bronchial hyperreactivity (BHR) is a pathophysiologic feature of asthma. It has been proposed that although there is no direct variable capable of assessing the small airways, a forced expiratory flow of between 25 and 75 percent (FEF25-75) might be considered a more sensitive early marker of... |
Purpose : Obesity is associated with disturbances of ventilatory functions in adults. But few studies have evaluated the pulmonary complications of obesity in the pediatric population. The purpose of this study is to clarify the effects of obesity on pulmonary function and body composition in obese children. Methods : Forty seven obese children whose ages ranged from nine to twelve... |
Purpose : To evaluate the patterns of preoperative pulmonary function tests(PFTs) and their correlation with postoperative pulmonary impairment in patients with adolescent idiopathic scoliosis(AIS), who had orthopaedic operation with or without rib resection thoracoplasty. Methods : The case records and radiographs of 79 patients(12, boys and 67, girls) of a mean age of 13.3 years(7-15 years) with AIS who underwent orthopaedic... |
Purpose : The incidence of obesity has increased in Korea recently. Obesity leads to higher risks of hypertension, hyperlipidemia and insulin resistance. It also leads to risks of respiratory complications. This study was performed to see the effects of obesity on children's pulmonary functions and on developed bronchospasm after exercise loading according to their obesity degrees. Methods : 257 obese... |
Purpose : To evaluate gas exchange, hemodynamics and pulmonary function during partial liquid ventilation(PLV) using PFC(perfluorodecalin), compared with conventional gas ventilation in newborn piglets with saline lavage-induced respiratory distress. Methods : In a total of 16 instrumented and ventilated piglets, acute respiratory distress(below 70 mmHg of PaO2 at FiO2 1.0) was induced by repeated saline pulmonary lavage. The piglets were randomized... |
Purpose : To understand the characteristics of early childhood asthma, we evaluated and compared the characteristics between early persistent wheezers and late wheezers. Methods : From January, 1998 to December, 1998, 106 children aged six to seven years were divided into three groups according to the onset of wheezing : Early persistent wheezers(n=36) who had wheezing both before three years of... |
Purpose : We performed a pulmonary function test with simple, computerized spirometry composed of pneumotachometry and evaluated the predicted normal values of air flow rates and lung volumes in healthy Korean children. We calculated each of the simple and complex linear and logarithmic regression equations setting the predicted values. Methods : Four hundred and fifty-two healthy children were enrolled from December, 1994 to August, 1995.... |
Purpose : To get the normal predicted value of airway resistance in Korean primary school-aged children by using flow interrupter technique which is simple and easy enough to be applicable even to young children. Methods : Among all the children of one primary school, we selected 964 (Male 469, Female 495). Excluded children were out of normal range in growth with Korean standard and/or... |
Purpose : Pulmonary function test is an important diagnostic tool in neonatal intensive care. These tests provide a detailed assessment an infant's pulmonary status that can be used in several ways: to monitor the progression of lung disease, to streamline ventilator management, and to assess the infant's response to new treatments, such as surfactant replacement therapy or bronchodilator. The purpose... |
Purpose : Neonatal pulmonary function test(PFT) adds a new dimension to the understanding and care of the infant at risk for lung dysfunction. PFT can be identified the risk for pulmonary problems and safely and effectively diagnosed, quantified, and qualified the dysfunction. So it is possible to early institution of prophylatic respiratory therapy in such neonates and it can improved... |
Purpose : Bronchial asthma is a disorder that is characteized by symptoms of reversible airway obstruction and increased responsiveness of the bronchus and to quantify the degree of br onchial hyperresponsivenes can be very helpful in determing the severity of disease and the prognosis. But the Methacholine provocation test is not always easy to be performed in all patients. Thus... |
An objective evaluation of the degree of respiratory impairment in children depends on the establishment of standards of normal function. In addition to sex and growth, various factors such as race and geography have been shown to be important determinants of lung function. The purposes of this paper are to report the result of lung function tests performed on a... |
Pulmonary function test is one of the most important tools in the management of patients with respiratory tract diseases and allergic diseases. As with the difficulties in performing the test, it has been seldom used in pediatric field. But with the advent of simple, computerized tools, pediatric pulmonologist and allergist try to manage the patients using PFE. Still the normal... |
To evaluate the relationship between spontaneous diuresis and improvement of pulmonary function in respiratory distress syndrome, 15 premature neonates requiring mechanical ventilation for RDS, who admitted in NICU of Wonkwang University Hospital from January 1990 to June 1992, were studied. The results were as follows(results are mean¡¾SEM) 1) Mean birth weight of study infants was 1.82¡¾0.08Kg, and mean gestational age was 32.80¡¾0.54... |
In recent years pulmonary function tests have had a wide application in clinical pulmonary diseases. By combining a number of different pulmonary function tests, abnormality present in a particular patient can be defined. This narrows the list of possible diagnosis and allows to determine accurately the degree of impairment and assess the response to therapy. To assess the pulmonary function in... |
The purpose of this study was to determine the relationship between improvement of pulmonary, function and diuresis in respiratory distress syndrome. This study was based on 24 cases of RDS infants admitted in NICU of Ewha Womans University from January 1988 to December 1990. The results were as follows. 1) Mean birth weight of study cases was 2.11 kg with gestational age between 29〜39 weeks. 2) Maximum... |
To determine the frequency, severity, time course and relations of exercise induced changes in lung function, forty-one asthmatic children and fifteen control children were subjected to free running and forced vital capacity (FVC), one-second forced expiratory volume (FEV1), maximum mid-expiratory flow rate (FEF 25-75%), and peak expiratory flow rate (PEFR) were measured before and serially for 60 minutes following exercise. The results were as follows. 1) Significant... |
