Global prevalence of classic phenylketonuria based on Neonatal Screening Program Data: systematic review and meta-analysis
Hamid Reza Shoraka, Ali Akbar Haghdoost, Mohammad Reza Baneshi, Zohre Bagherinezhad, Farzaneh Zolala
Clin Exp Pediatr. 2020;63(2):34-43.   Published online February 6, 2020
Question: What is the global prevalence of classic phenylketonuria based on Neonatal Screening Program Data?
Finding: The overall worldwide prevalence of the disease is 6.002 per 100,000 neonates. The highest prevalence (38.13) was reported in Turkey, while the lowest (0.3) in Thailand.
Meaning: This difference in the prevalence may be due to differences in the number of consanguineous marriages among the different regions, phenylalanine cutoff points, and sample sizes.

Comparative validity of microalbuminuria versus clinical mortality scores to predict pediatric intensive care unit outcomes
Shifa Nismath, Suchetha S. Rao, B.S. Baliga, Vaman Kulkarni, Gayatri M. Rao
Clin Exp Pediatr. 2020;63(1):20-24.   Published online August 12, 2019
Question: Does microalbuminuria predict mortality in pediatric intensive care unit?
Finding: Positive correlation was found between albumin-creatinine ratio and pediatric intensive care unit stay, organ dysfunction and need of inotropes. Area under the receiver operating characteristic curve for albumin-creatinine ratio was comparable to mortality scores.
Meaning: Microalbuminuria is a good predictor of outcome in pediatric intensive care unit and is comparable with mortality scores.

Ensiyeh Jenabi, Saeid Bashirian, Salman Khazaei
Clin Exp Pediatr. 2020;63(1):8-13.   Published online November 7, 2019
Autism spectrum disorder is a common neurodevelopmental disorder with an unknown etiology. The correlation between neonatal jaundice and the risk of developing autism spectrum disorder was investigated previously. Some studies showed significant associations, whereas others demonstrated no association. In this meta-analysis, we pooled the results of observational studies to examine the association between neonatal jaundice and the risk of autism...

High-flow nasal cannula oxygen therapy in children: a clinical review
Ji-Won Kwon
Clin Exp Pediatr. 2020;63(1):3-7.   Published online October 28, 2019
High-flow nasal cannula (HFNC) is a relatively safe and effective noninvasive ventilation method that was recently accepted as a treatment option for acute respiratory support before endotracheal intubation or invasive ventilation. The action mechanism of HFNC includes a decrease in nasopharyngeal resistance, washout of dead space, reduction in inflow of ambient air, and an increase in airway pressure. In preterm...

Clin Exp Pediatr. 2019;62(12):450-455.   Published online October 28, 2019
Background: Lipid accumulation product (LAP) is associated with the presence and severity of nonalcoholic fatty liver disease (NAFLD) in adults.

Hypoxia-inducible factor: role in cell survival in superoxide dismutase overexpressing mice after neonatal hypoxia-ischemia
Ga Won Jeon, R. Ann Sheldon, Donna M Ferriero
Clin Exp Pediatr. 2019;62(12):444-449.   Published online October 18, 2019
Background: Sixty percent of infants with severe neonatal hypoxic-ischemic encephalopathy die, while most survivors have permanent disabilities. Treatment for neonatal hypoxic-ischemic encephalopathy is limited to therapeutic hypothermia, but it does not offer complete protection. Here, we investigated whether hypoxia-inducible factor (HIF) promotes cell survival and suggested neuroprotective strategies.
Purpose: HIF-1α-deficient mice have increased brain injury after neonatal hypoxia-ischemia (HI), and the...

Reconsideration of urine culture for the diagnosis of acute pyelonephritis in children: a new challenging method for diagnosing acute pyelonephritis
Jun Ho Lee, Seonkyeong Rhie
Clin Exp Pediatr. 2019;62(12):433-437.   Published online October 18, 2019
Acute pyelonephritis (APN) should be detected and treated as soon as possible to reduce the risk of the development of acquired renal scarring. However, in the medical field, urine culture results are not available or considered when the prompt discrimination of APN is necessary and empirical treatment is started. Furthermore, urine culture cannot discriminate APN among children with febrile urinary...

Association between Body Mass Index and Hepatitis B antibody seropositivity in children
Yoowon Kwon, Su Jin Jeong
Clin Exp Pediatr. 2019;62(11):416-421.   Published online August 12, 2019
Background: The seropositivity rate of hepatitis B surface antigen (anti-HBs) antibodies is known to be ≥95% after hepatitis B virus vaccination during infancy. However, a low level or absence of anti-HBs in healthy children is discovered in many cases. Recent studies in adults reported that a reduced anti-HBs production rate is related to obesity.
Purpose: To investigate whether body mass index...

Clinical impact of admission hypothermia in very low birth weight infants: results from Korean Neonatal Network
Na Hyun Lee, Soo Kyung Nam, Juyoung Lee, Yong Hoon Jun
Clin Exp Pediatr. 2019;62(10):386-394.   Published online May 22, 2019
