Clin Exp Pediatr. 2011;54(2):69-78.   Published online February 28, 2011
Purpose

The aim of this study was conducted to investigate the mean nRBC count in very low births weight infants (VLBWIs) and to determine the usefulness of the nRBC as an independent prognostic factors of perinatal complications in VLBWIs.

Methods

This study was conducted on 112 VLBWIs who were hospitalized in the neonatal intensive care unit (NICU) of the author's hospital within the...

Reference values for respiratory system impedance using impulse oscillometry in healthy preschool children
Jye Hae Park, Jung Won Yoon, Youn Ho Shin, Hye Mi Jee, Young Sun Wee, Sun Jung Chang, Jung Hwa Sim, Hye Yung Yum, Man Yong Han
Clin Exp Pediatr. 2011;54(2):64-68.   Published online February 28, 2011
Purpose

The normal values for lung resistance and lung capacity of children, as determined by impulse oscillometry (IOS), are different for children of different ethnicities. However, reference values there is no available reference value for Korean preschool children have yet to be determined. The aim of the present study was to determine the normal ranges of IOS parameters in Korean preschool...

Normative data of penile length in Korean newborns
Sang Yeob Kim, Jae Sung Jun, Sang Geel Lee
Clin Exp Pediatr. 2008;51(9):944-949.   Published online September 15, 2008
Purpose : As modern society has became more open, interest in healthy internal and external growth has increased, including that pertaining to penile length in children. A micropenis is defined as one where penile length is more than 2 SD (standard deviation) below the mean, and it can be traced back to chromosome and endocrine disorders. The authors executed this...
Normal antistreptolysin O titers of children by age group in the Gyeonggi-Incheon region

Clin Exp Pediatr. 2007;50(10):965-969.   Published online October 15, 2007
Purpose : Measurement of antistreptolysin O (ASO) is often necessary to confirm a clinical diagnosis of recent streptococcal infection, especially in patients suspected of rheumatic fever and acute glomerulonephritis. Standard normal ranges for ASO should be established locally for each age group. We analyzed ASO to determine the upper limit of normal (ULN) ASO in children in the Gyeonggi-Incheon area. Methods...
Reference values for respiratory system impedance using impulse oscillometry in school-aged children in Korea
Young Sun Wee, Hyoung Yun Kim, Da Wun Jung, Hye Won Park, Yoon Ho Shin, Man Yong Han
Clin Exp Pediatr. 2007;50(9):862-867.   Published online September 15, 2007
Purpose : The impulse oscillometry (IOS) is applicable to young children because it requires minimal cooperation and a non-invasive method to measure the mechanics of respiratory system. This study aimed to develop the reference values in school-aged children in Korea, using IOS which is a modification of forced oscillation technique (FOT). Methods : Measurements were performed in 92 previously untrained healthy...
Quantification of Age-related Reference Values for Urinary Organic Acids in the Healthy Korean Population
Yong Jae Choi, In Cheol Kim, You Kyoung Choi, Hong Jin Lee, Bong Sung Kim, Won Il Park, Kyoung Ja Lee, T. Giudic, M. Blaskovics
Clin Exp Pediatr. 2001;44(12):1413-1423.   Published online December 15, 2001
Purpose : For the accurate diagnosis of organic acidopathies, quantification of urinary organic acid should be done and we should know the normal ranges of each organic acid excreted in the urine. The amount of organic acids excreted in the urine shows wide variability according to ethnic group, diet and age. We have quantified 82 organic acids to make a Korean reference value. Methods...
Hematologic Reference Values of Peripheral Blood in Healthy Newborns and Infants.
Nam Hyuk Joo, Hong Ja Kang, Soon Ho Kim
Clin Exp Pediatr. 1990;33(4):481-490.   Published online April 30, 1990
To estimate hematologic reference values of the peripheral blood of newnboms and infants, the author examined the routine hematologic parameters by heel or finger puncture in 73 cases of first day newborn, 64 cases of 7 day newborns, 10 cases of 2 month infants, 14 cases of 3~6 month infants and 13 cases of 15~18 month children. The routine hematologic parameters including red cell...
