BACKGROUND: Despite the expansion of antenatal syphilis screening programs, congenital syphilis (CS) remains a concern. PURPOSE: This study aimed to analyze the manifestation and progress of CS, including treatment and follow-up, based on a nationwide study. METHODS: From the Korean National Health Insurance Service database, a total of 548 infants were examined for CS during their first year of life from 2013 to 2018. Neurosyphilis and complications were investigated using the International Cla

Despite advances in obstetric care, hypoxic ischemic encephalopathy (HIE) remains a significant disease burden. We determined the national trends of HIE prevalence, therapeutic hypothermia (TH) use, mortality, and outcomes from 2012 to 2019. This study included term infants diagnosed with HIE between 2012 and 2019 from the National Health Insurance Service database. The prevalence of HIE was 2.4 per 1000 births without significant change during the period. TH was performed in approximately 6.7%

Risk factors for rickets of prematurity have not been re-examined since introduction of high mineral formula, particularly in ELBW infants. We analyzed the incidence and the risk factors of rickets in extremely low birth weight (ELBW) infants. As a retrospective case-control study from 2004 to 2008, risk factors were analyzed in 24 patients with rickets versus 31 patients without. The frequency of rickets in ELBW infants was 24/55 (44%). Infants with rickets were diagnosed at 48.2 ± 16.1 days of

AIM: We investigated the significance of the calculated delta neutrophil index (DNI) as a diagnostic factor for neonatal sepsis. METHODS: In retrospective study, 24 infants were diagnosed with blood culture-proven sepsis, and 48 non-septic neonates matched for gestational age, and birth weight served as controls. Among the 24 infants with sepsis, 5 died within 7 days at diagnosis. RESULTS: Mean DNI (at diagnosis, after 24 h and 72 h), CRP and WBC counts were significantly higher, and neutrophil

To evaluate national epidemiologic data on infants treated for patent ductus arteriosus (PDA) in Korea and analyze outcomes associated with different PDA treatments. We retrospectively evaluated data on 12,336 patients diagnosed with PDA (International Classification of Diseases-10 code: Q250) between 2015 and 2018 from the Health Insurance Review and Assessment database. Among them, 1623 patients underwent surgical ligation (code: O1671). We used birth certificate data from Statistics Korea to

BACKGROUND: Sudden infant death syndrome (SIDS) still remains one of the leading causes of infant death worldwide, especially in high-income countries. To date, however, there is no detailed information on the global health burden of SIDS. AIMS: To characterize the global disease burden of SIDS and its trends from 1990 to 2019 and to compare the burden of SIDS according to the socio-demographic index (SDI). DESIGN: Systematic analysis based on the Global Burden of Disease (GBD) 2019 data. METHOD

PURPOSE: Hypothermia at admission is associated with increased mortality and morbidity in preterm infants. We performed a quality improvement (QI) effort to determine the impact of a decrease in admission hypothermia in preterm infants. METHODS: The study enrolled very low birth weight (VLBW) infants born at Gangnam Severance Hospital between January 2013 and December 2016. This multidisciplinary QI effort included the use of occlusive wraps, warm blankets, and caps; the delivery room temperatur

The risk of neurodevelopmental disorders in low birth weight (LBW) infants has gained recognition but remains debatable. We investigated the risk of attention-deficit/hyperactivity disorder (ADHD) and autism spectrum disorder (ASD) in school-aged children according to their birth weight. We conducted a retrospective cohort study using the Korean National Health Insurance claims data of 2,143,652 children who were born between 2008 and 2012. Gestational age of infants was not available; thus, out

BACKGROUND: Pulmonary surfactant (PS) replacement therapy, as a safe and effective treatment for respiratory distress syndrome (RDS) may have further increased with the extended insurance coverage since 2011 in Korea. Thus, this study aimed to investigate the epidemiologic data of PS replacement therapy for RDS in Korea and to analyze the complications associated with RDS. METHODS: We included 19,442 infants who were treated with PS and diagnosed with RDS (International Classification of Disease

Ornithine transcarbamylase (OTC) deficiency is well known as the most common inherited disorder of the urea cycle, and 1 of the most common causes of hyperammonemia in newborns. We experienced a case of a 3-day-old boy with OTC deficiency who appeared healthy in the first 2 days of life but developed lethargy and seizure soon afterwards. His serum ammonia level was measured as >1700 µg/dL (range, 0 to 45 µg/dL). Continuous renal replacement therapy (CRRT) in the mode of continuous venovenous hem

PURPOSE: The aims of the study were to develop and evaluate a machine learning model with which to predict postnatal growth failure (PGF) among very low birth weight (VLBW) infants. MATERIALS AND METHODS: Of 10425 VLBW infants registered in the Korean Neonatal Network between 2013 and 2017, 7954 infants were included. PGF was defined as a decrease in Z score >1.28 at discharge, compared to that at birth. Six metrics [area under the receiver operating characteristic curve (AUROC), accuracy, preci

Purpose: The goal of nutritional support for very-low-birth-weight (VLBW) infants from birth to term is to match the in utero growth rates; however, this is rarely achieved. Methods: We evaluated postdischarge growth patterns and growth failure in 81 Korean VLBW infants through a retrospective study. Weight and height were measured and calculated based on age percentile distribution every 3 months until age 24 months. Growth failure was defined as weight and height below the 10th percentile at 2

We aimed to evaluate risk factors for growth failure in very low birth weight (VLBW) infants at 18-24 months of corrected age (follow-up1, FU1) and at 36 months of age (follow-up2, FU2). In this prospective cohort study, a total of 2,943 VLBW infants from the Korean Neonatal Network between 2013 and 2015 finished follow-up at FU1. Growth failure was defined as a z-score below -1.28. Multiple logistic regression was used to analyze risk factors for growth failure after dividing the infants into s

Montelukast was not effective in reducing moderate or severe BPD. There were no significant adverse drug events associated with Montelukast treatment.
