Clin Exp Pediatr. 2018;61(9):285-290.   Published online September 15, 2018

Purpose: To study the usefulness of the procalcitonin (PCT) test in young febrile infants between 1 and 3 months of age. Methods: We evaluated the medical records of 336 febrile infants between 1 and 3 months of age who visited the Emergency Department or outpatient department of Samsung Changwon Hospital from May 2015 to February 2017, and analyzed the clinical characteristics...

Clin Exp Pediatr. 2018;61(8):258-263.   Published online August 15, 2018

Purpose: Macrolide-resistant Mycoplasma pneumoniae pneumonia (MPP) is characterized by prolonged fever and radiological progression despite macrolide treatment. Few studies have examined serum procalcitonin (PCT) level in children with MPP. We aimed to investigate the association of acute inflammation markers including PCT with clinical parameters in children with MPP. Methods: A total of 147 children were recruited. The diagnosis of MPP...

Clinical usefulness of serum procalcitonin level in distinguishing between Kawasaki disease and other infections in febrile children
Na Hyun Lee, Hee Joung Choi, Yeo Hyang Kim
Clin Exp Pediatr. 2017;60(4):112-117.   Published online April 25, 2017
Purpose

The aims of this study were to compare serum procalcitonin (PCT) levels between febrile children with Kawasaki disease (KD) and those with bacterial or viral infections, and assess the clinical usefulness of PCT level in predicting KD.

Methods

Serum PCT levels were examined in febrile pediatric patients admitted between August 2013 and August 2014. The patients were divided into 3 groups as...

Neonatology (Perinatology)
The influencing factors on procalcitonin values in newborns with noninfectious conditions during the first week of life
Jueseong Lee, Yong Hyeon Bang, Eun Hee Lee, Byung Min Choi, Young Sook Hong
Clin Exp Pediatr. 2017;60(1):10-16.   Published online January 16, 2017
Purpose

Although procalcitonin (PCT) level is useful for the diagnosis of neonatal sepsis, PCT reliability is inconsistent because of the varied conditions encountered in neonatal intensive care units. This study aimed to investigate PCT levels and factors influencing increased PCT levelin newborns without bacterial infection during the first week of life.

Methods

In newborns hospitalized between March 2013 and October 2015, PCT levels...

Serum procalcitonin as a diagnostic marker of neonatal sepsis
In Ho Park, Seung Hyun Lee, Seung Taek Yu, Yeon Kyun Oh
Clin Exp Pediatr. 2014;57(10):451-456.   Published online October 31, 2014
Purpose

We evaluated serum procalcitonin (PCT) as a diagnostic marker of neonatal sepsis, and compared PCT levels with C-reactive protein (CRP) levels.

Methods

We retrospectively reviewed the medical records of 269 neonates with a suspected infection, admitted to Wonkwang University School of Medicine & Hospital between January 2011 and December 2012, for whom PCT and CRP values had been obtained. Neonates were categorized...

A study of neuropeptides related to headaches in children with meningeal irritation signs
Bo Gil Seo, Myung Hwan Yoo, Jae Won Shim, Jung Yeon Shim, Hye Lim Jung, Moon Soo Park, Deok-Soo Kim
Clin Exp Pediatr. 2006;49(5):533-538.   Published online May 15, 2006
Purpose : The headache, one of the symptoms of meningitis, is related to abrupt elevation of intracranial pressure(ICP) or stimulation of intracranial nociceptive structure. However, in cases of mild elevation of ICP or normal findings of cerebrospinal fluid(CSF) analysis, patients sometimes complain of headaches. Therefore, other pathways may contribute to the occurrence of headaches in aseptic meningitis or meningismus. We...
Usefulness of serum procalcitonin test for the diagnosis of upper urinary tract infection in children
Dong Wook Kim, Ju Young Chung, Ja Wook Koo, Sang Woo Kim, Tae Hee Han
Clin Exp Pediatr. 2006;49(1):87-92.   Published online January 15, 2006
Purpose : It is difficult to make a distinction between lower urinary tract infection(UTI) and acute pyelonephritis(APN) during the acute phase of febrile UTI due to nonspecific clinical symptoms and laboratory findings, especially among young children. We measured the serum procalcitonin(PCT) in children with UTI to distinguish between acute pyelonephritis and lower UTI, and to determine the accuracy of PCT...
Childhood Infection-associated Hypocalcemia

Clin Exp Pediatr. 1993;36(2):223-231.   Published online February 15, 1993
The causes of hypocalcemia in patients suffering from severe infection including sepsis are largely uncertain. So we measured serum albumin, total protein, cholesterol, PTH, and calcitonin of the infection-associated hypocalcemic chlidren and compared with those of normocalcemic children department of pediatrics of Gyeongsang National University Hospital. Hypocalcemic patients were compared to the decreased amount of serum albumin in the hypocalcemic...
A Study on Serum Ca, P, Mg, Parathyroid Hormone, Calcitionin, and 1, 25-dihydroxyvitamin D Concentrations in Normal Newborn and Low Birth Weight Infants.

Early neonatal hypocalcemia occurs within the first few days of life, with the lowest concentrations of serum calcium being reached at 24 to 48 hours of age. An infant can be considered to be hypocalcemic when serum calcium concentrations are below 7 mg/dl or when ionized calcium concentrations are below 3 to 3.5 mg/dl. The most commonly encountered causes of neonatal hypocalcemia are prematurity,...
