Clin Exp Pediatr. 1999;42(8):1159-1164.   Published online August 15, 1999
Propionic acidemia is an autosomal-recessive inborn error of branched-chain amino acid metabolism. It is caused by deficient activity of propionyl-coenzyme A carboxylase and is characterized by a spectrum of clinical and biochemical findings. It usually manifests in the neonatal period or early infancy. Since Childs et al first described the propionic acidemia of infants in 1961, it has rarely been...

Intralipid Infusions Effect on Nutrophil Elastase Level in Newborns
Sue Jeen Min, Yong Woon Baek, Yong Woon Baek, Yong Woon Baek
Clin Exp Pediatr. 1999;42(5):666-671.   Published online May 15, 1999
Purpose : Parenteral nutrition is given to infants who tempararily cannot take oral feeding adequately. A lipid emulsion is added to the parenteral to supply essential fatty acids. In neonatal sepsis, elastase from azuropilic granules of the neutrophils is released and rapidly bound to α1- Proteinase Inhibitor(α1-PI). The lipid emulsion has been noted to markedly inhibit chemotaxis of neutrophils, so...

Jae Eun Lee, Seung Woo Baeck, Wan Seob Kim, Chun Hee Lee
Clin Exp Pediatr. 1999;42(1):128-132.   Published online January 15, 1999
Individuals with Down syndrome have a high incidence of hematologic diseases such as transient myeloproliferative disorder(TMD) & acute leukemia. Because it is difficult to distinguish TMD from acute myeloblastic leukemia, the diagnosis in neonate, who have Down syndrome, should be made with extreme caution. TMD usually undergoes spontaneous remission within a few months, but acute leukemia can develope after remission...
