목 적 : 최근 체계적인 산전 관리 및 다양한 인공호흡기 치료를 비롯한 신생아집중치료술의 발전은 극소저출생체중아 생존율의 많은 향상을 가져왔다. 그러나 극소저출생체중아에서의 허혈성, 저산소성손상의 주된 병변인 뇌실주위백질연화증 및 중증뇌실출혈의 발생 위험성은 여전히 크다. 두 질환에 있어 여러 가지 산전, 산후 위험요소와 더불어 신생아집중치료실에서의 인공호흡기 치료는 뇌혈류의 변화를 유발하는 위험인자로 간주되고 있다. 이에 인공호흡기 치료가 두 질환의 발생에 있어 위험인자로서 작용하는 지를 알아보고자 하였다. 방 법 : 1999년 1월부터 2003년 12월까지 5년간 대구파티마병원에서 출생한 신생아 중에서 신생아집중치료실에 1개월 이상 입원 치료를 받았던 출생체중 1,500 g 미만의 극소저출생체중아 255명을 대상으로 하였다. 이 중 뇌실주위백질연화증 환아 15명 및 중증뇌실출혈 환아 8명, 총 23명을 연구군으로 하였다. 전체 대상 255명 중 인공호흡기 치료를 받았던 환아는 139명이었다. 모든 대상아는 병력지를 기초로 산전 및 산후 병력 및 임상적 특성, 인공호흡기 치료 중 경과를 분석하였고, 뇌초음파검사 결과를 토대로 선별하였다. 결 과 : 전체 255례 중 뇌실주위백질연화증은 16례, 중증뇌실출혈은 8례였고, 출생체중이 작을수록 발생빈도는 더 높았다. 전체 대상 중 인공호흡기 치료병력이 있었던 환아가 139례였고 그 중 15례에서 뇌실주위백질연화증이, 8례에서 중증뇌실출혈이 발생하였다. 반면에, 인공호흡기 치료병력이 없었던 나머지 124례에서는 뇌실주위백질연화증 1례만이 발생하였다. 병력지를 기초로 한 후향적 조사에서 뇌실주위백질연화증과 연관되는 위험인자로서 유의할만한 것은 출생 시 가사(Apgar 점수<5), 무호흡, 인공호흡기 치료병력, 패혈증 및 산혈증이 있었고, 중증뇌실출혈의 경우는 출생 시 가사, 무호흡, 인공호흡기 치료병력, 호흡곤란증후군 및 산혈증이 유의할만 하였다. 인공호흡기 치료를 받았던 139례 중 두 질환군의 경우 이환되지 않았던 환아들에 비해 출생 당시 가사, 산혈증 및 무호흡의 병력이 더 많았고, 인공호흡기 치료 시 고농도의 흡입산소가 필요했던 경우와 장기간의 인공호흡기 치료가 필요했던 경우도 많았다. 결 론 : 다른 연구에서와 같이 본 연구에서도 인공호흡기 치료가 중증뇌실출혈과 뇌실주위백질연화증의 발생과 연관이 있는 것으로 나타났다. 그러나 분만 당시 인공호흡기 치료를 필요로 하는 선행 위험인자를 가지는 경우가 대부분이고, 또한 최근의 인공호흡기 치료기법의 발전으로 인해 인공호흡기 치료 자체가 중증뇌실출혈과 뇌실주위백질연화증의 직접적인 원인이라고 생각되어지지는 않으며 인공호흡기 치료가 요구되어지는 선행질환의 중증도가 더 직접적인 위험요소로 작용할 것으로 추정된다. 결론적으로 적절한 인공호흡기 치료와 더불어 보다 전문적인 산전 관리가 뇌실주위백질연화증 및 중증뇌실출혈의 발생빈도를 줄이는 중요한 수단이 될 것이라고 생각된다.

The obesity epidemic is a worldwide problem. Factors predisposing to obesity include genetics, race, socioeconomic conditions, birth by cesarean section, and perinatal antibiotic use. High protein (HP) content in infant formulas has been identified as a potential culprit predisposing to rapid weight gain in the first few months of life and leading to later obesity. In a large multicountry study the effects of lower protein (LP) formula (1.77 and 2.2 g protein/100 kcal, before and after the 5th month, respectively) were compared to those of higher protein (2.9 and 4.4 g protein/100 kcal, respectively). Results indicated that at 24 months, the weight-for-length z score of infants in the LP formula group was 0.20 (0.06, 0.34) lower than that of the HP group and was similar to that of the breastfed reference group. The authors concluded that a HP content of infant formula is associated with higher weight in the first 2 years of life but has no effect on length. LP intake in infancy might diminish the later risk of overweight and obesity. At 6 years of age HP children had a significantly higher body mass index (by 0.51; 95% confidence interval [CI], 0.13-0.90; p=0.009) and a 2.43 (95% CI, 1.12-5.27; p=0.024) fold greater risk of becoming obese than those who received the LP. In conclusion, several factors may influence development of metabolic syndrome and obesity. Breastfeeding should always be encouraged. An overall reduction of protein intake in formula non breastfed infants seems to be an additional way to prevent obesity.

Background: Severe perinatal asphyxia results in multiple organ involvement, neonate hospitalization, and eventual death. Purpose: This study aimed to investigate the predictive factors of death in newborns with hypoxic-ischemic encephalopathy (HIE) receiving selective head cooling. Methods: This cross-sectional descriptive-retrospective study was conducted from 2013 to 2018 in Fatemieh Hospital of Hamadan and included 51 newborns who were admitted to the neonatal intensive care unit with a diagnosis of HIE. Selective head cooling for patients with moderate to severe HIE began within 6 hours of birth and continued for 72 hours. The required data for the predictive factors of death were extracted from the patients' medical files, recorded on a premade form, and analyzed using SPSS ver. 16. Results: Of the 51 neonates with moderate to severe HIE who were treated with selective head cooling, 16 (31%) died. There were significant relationships between death and the need for advanced neonatal resuscitation (P=0.002), need for mechanical ventilation (P=0.016), 1-minute Apgar score (P=0.040), and severely abnormal amplitude-integrated electroencephalography (a-EEG) (P=0.047). Multiple regression of variables or data showed that the need for advanced neonatal resuscitation was an independent predictive factor of death (P=0.0075) and severely abnormal a-EEG was an independent predictive factor of asphyxia severity (P=0.0001). Conclusion: All cases of neonatal death in our study were severe HIE (stage 3). Advanced neonatal resuscitation was an independent predictor of death, while a severely abnormal a-EEG was an independent predictor of asphyxia severity in infants with HIE.

Intraventricular hemorrhage (IVH) is a serious concern for preterm infants and can predispose such infants to brain injury and poor neurodevelopmental outcomes. IVH is particularly common in preterm infants. Although advances in obstetric management and neonatal care have led to a lower mortality rate for preterm infants with IVH, the IVH-related morbidity rate in this population remains high. Therefore, the present review investigated the pathophysiology of IVH and the evidence related to interventions for prevention. The analysis of the pathophysiology of IVH was conducted with a focus on the factors associated with cerebral hemodynamics, vulnerabilities in the structure of cerebral vessels, and host or genetic predisposing factors. The findings presented in the literature indicate that fluctuations in cerebral blood flow, the presence of hemodynamic significant patent ductus arteriosus, arterial carbon dioxide tension, and impaired cerebral venous drainage; a vulnerable or fragile capillary network; and a genetic variant associated with a mechanism underlying IVH development may lead to preterm infants developing IVH. Therefore, strategies focused on antenatal management, such as routine corticosteroid administration and magnesium sulfate use; perinatal management, such as maternal transfer to a specialized center; and postnatal management, including pharmacological agent administration and circulatory management involving prevention of extreme blood pressure, hemodynamic significant patent ductus arteriosus management, and optimization of cardiac function, can lower the likelihood of IVH development in preterm infants. Incorporating neuroprotective care bundles into routine care for such infants may also reduce the likelihood of IVH development. The findings regarding the pathogenesis of IVH further indicate that cerebrovascular status and systemic hemodynamic changes must be analyzed and monitored in preterm infants and that individualized management strategies must be developed with consideration of the risk factors for and physiological status of each preterm infant.

Global developmental delay (GDD) is a relatively common early-onset chronic neurological condition, which may have prenatal, perinatal, postnatal, or undetermined causes. Family history, physical and neurological examinations, and detailed history of environmental risk factors might suggest a specific disease. However, diagnostic laboratory tests, brain imaging, and other evidence-based evaluations are necessary in most cases to elucidate the causes. Diagnosis of GDD has recently improved because of remarkable advances in genetic technology, but this is an exhaustive and expensive evaluation that may not lead to therapeutic benefits in the majority of GDD patients. Inborn metabolic errors are one of the main targets for the treatment of GDD, although only a small proportion of GDD patients have this type of error. Nevertheless, diagnosis is often challenging because the phenotypes of many genetic or metabolic diseases often overlap, and their clinical spectra are much broader than currently known. Appropriate and cost-effective strategies including up-to-date information for the early identification of the "treatable" causes of GDD are needed for the development of well-timed therapeutic applications with the potential to improve neurodevelopmental outcomes.

Cerebral palsy is a neurodevelopmental impairment caused by a nonprogressive defect or lesion in single or multiple locations in the immature brain. The defect or lesion can occur in utero or during or shortly after birth and produces sensory-motor impairment that are usually evident in early infancy. The causes of cerebral palsy are not completely understood, certain prenatal, perinatal, and postnatal factors have been associated with cerebral palsy. This study was analysed the clinical features of 50 children with cerebral palsy (29 males and 21 females) in National Rehabilitation Hospital from March 17 to June 27, 1998. The time of initial visit was over than 12 months in 74%, and their cheif complains were delayed developments (78%). The preterm infants were 40% and the infants with low birth weight were 36%. The maternal age at childbirth was over than 30 years old in 52%. The most common type of cerebral palsy was spastic (54%), mixed (22%), athetosis and hypotonia (10% each), ataxia (4%). The cerebral palsy with preterm infants and low birth weight were more likely to have spastic type (P=0.002, P=0.023 each). The most preterm infants were born between 30 and 35 years old of maternal age, and there were statistical significance in difference (P=0.031).

Environmental contaminants are one of the important causal factors for development of various human diseases. In particular, the perinatal period is highly vulnerable to environmental toxicants and resultant dysregulation of fetal development can cause detrimental health outcomes potentially affecting life-long health. Perfluoroalkyl compounds (PFCs), emerging environmental pollutants, are man-made organic molecules, which are widely used in diverse industries and consumer products. PFCs are non-degradable and bioaccumulate in the environment. Importantly, PFCs can be found in cord blood and breast milk as well as in the general population. Due to their physicochemical properties and potential toxicity, many studies have evaluated the health effects of PFCs. This review summarizes the epidemiological and experimental studies addressing the association of PFCs with neurotoxicity and immunotoxicity. While the relationships between PFC levels and changes in neural and immune health are not yet conclusive, accumulative studies provide evidence for positive associations between PFC levels and the incidence of attention deficit hyperactivity disorder and reduced immune response to vaccination both in children and adults. In conclusion, PFCs have the potential to affect human health linked with neurological disorders and immunosuppressive responses. However, our understanding of the molecular mechanism of the effects of PFCs on human health is still in its infancy. Therefore, along with efforts to develop methods to reduce exposure to PFCs, studies on the mode of action of these chemicals are required in the near future.

Objectives: Regression, while not a core symptom of autism spectrum disorder (ASD), has been suggested to be a distinct subtype by previous studies. Therefore, this study aimed to explore the prevalence and clinical differences between those with and without regression in children with ASD. Methods: This study includes data from toddlers and young children aged 2-7 years acquired from other projects at Seoul National University Bundang Hospital. The presence and characteristics of regression were explored using question items #11-28 from the Autism Diagnostic Interview-Revised. Chi-square and independent t-tests were used to compare various clinical measurements such as autistic symptoms, adaptative behavior, intelligence, and perinatal factors. Results: Data from 1438 young children (1020 with ASD) were analyzed. The overall prevalence rate of regression, which was mainly related to language-related skills, was 10.2% in the ASD group, with an onset age of 24 months. Regarding clinical characteristics, patients with ASD and regression experienced ASD symptoms, especially restricted and repetitive interests and behaviors, with greater severity than those without regression. Furthermore, there were significant associations between regression and hypertension/placenta previa. Conclusion: In-depth surveillance and proactive interventions targeted at young children with ASD and regression should focus on autistic symptoms and other areas of functioning.
