Previous studies suggest that the concentration of 25-hydroxyvitamin D [25(OH)D] in cord blood may show an inverse association with respiratory tract infections (RTI) during childhood. The aim of the present study was to examine the influence of 25(OH)D concentrations in cord blood on infant RTI in a Korean birth cohort.

Methods

The levels of 25(OH)D in cord blood obtained from 525 Korean...

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...
