2.Pulmonary Venous Flow Pattern by Color Doppler Echocardiography in Childhood.
Korean Circulation Journal 1994;24(2):259-271
BACKGROUND: Biphasic or triphasic or quadriphasic pattern of pulmonary venous flow has been described by color Doppler echocardiography in normal subjects. Absolute velocity measurements varied with the position of the probe in relation to the pulmonary vein. The purpose of this study is to evaluate the normal pulmonary venous flow pattern and compare the data according to age, body weight, height and body surface area. METHODS: 244 normal children underwent transthoracic echocardiography from December 1992 to July 1993. Age ranged from newborns to 13 years. From the apical four chamber view, pulmonary venous flow velocity and integral were obtained. RESULTS: Quadriphasic pulmonary flow pattern(early systolic flow, late systolic flow, diastolic flow, atrial reversal flow) was identified. Pulmonary venous peak flow velocity was not different according to increasement of age, body weight, height or body surface area. But pulmonic flow integral was significantly increased according as increasement of age, body weight, height, or body surface area. CONCLUSION: Transthoracic color Doppler echocardiography is a good noninvasive diagnostic tool to evaluate pulmonary venous flow pattern in children.

4.Pulmonary Venous Flow Pattern by Doppler Echocardiography before and after Closure of Ductus Arteriosus in Newborns.
Journal of the Korean Pediatric Society 1994;37(9):1213-1219
Color Doppler echocardiography was performed to evaluate pulmonary venous flow pattern at 1st~2nd day of birth in 84 fullterm newborns (36: patent ductus arteiosus, 48: closed ductus arteriosus). Aortic and pulmonic diameter, velocity and integral were estimated. The purpose of this study ascertained that patent ductus arteriousus changed the pulmonary vein velocity and flow integral. The results were as follows. 1) There was no significant difference in aortic diameter and peak velocity, but significant difference in flow integral before and after closure of ductus arteriosus. 2) There was no significant difference in pulmonic velocity and flow integral, but significant difference in diameter before and after closure of ductus arteriosus. 3) Early systolic flow velocity, late systolic flow velocity, diastolic flow velocity in pulmonary vein were higher in patent ductus arteriosus group at 1st~2nd day, but atrial reversal flow velocity was not significantly different. 4) Diastolic pulmonary venous flow integral was higher in patent ductus arteriosus group at 1st~2nd day. Thus four distinct phases(early systolic wave, late systolic wave, diastolic wave, and atrial reversal wave) were identified before and after closure of ductus arteriosus. Left to right shunt via ductus arteriosus increased systolic, diastolic pulmonic venous velocity and diastolic flow integral. We will investigate pulmonary venous flow patterns in other left to right congenital heart diseases or mitral regurgitation.

The allergic skin test and RAST are used commonly to demonstrate the presence of skin sensitizing IgE antibody in the diagnosis of allergic disease. To evaluate the agreement rate and correlation between results of skin test and RAST (radioallergosorbent test) in allergic subject, 83 allergic childhood with positive skin test (bronchial asthma: 26, allergic rhinitis: 27, atopic dermatitis and urticaria: 6 bronchial asthma and allergic rhinitis: 24) and 16 nonallergic childhood were studied. The results were as follows. 1) Peripheral eosinophil counts were significantly elevated in groups with bronchial asthma, allergic rhinitis, bronchial asthma & allergic rhinitis except atopic dermatitis & urticaria group in comparison with normal control group. 2) Serum IgE levels were significantly higher in groups with bronchial asthma, allergic rhinitis, bronchial asthma & allergic rhinitis than in normal control group except atopic dermatitis & urticaria group but there was no significant differences among study groups. 3) RAST units of D.p and D.f were significantly higher in study group except atopic dermatitis & urticaria group. RAST units of cockroach, however, were not significantly increased but in D.f, combined group of bronchial asthma & allergic rhinitis was significantly higher than bronchial asthma or allergic rhinits (p<0.05). 4) Each agreement rate between 3+ skin test and positive rate of RAST in D.p, D.f, cockroach was 37.5%, 63.6% and 12.5% respectively and 4+ skin test and positive rate of RAST was 84.0%, 89.1% and 38.4%. 5) Correlation coefficient between skin test and RAST was 0.71 in D.P, 0.59 in D.f and 0.23 in cockroach. In conclusion, there was difference in agreement rate between positive skin test and RAST to each allergen. Agreement rate between positive skin test and RAST was higher in D.p and D.f. These results suggest that RAST can be used simultaneously with skin test for detecting allergens.
