자폐장애와 fragile X증후군의 관련성과 자폐장애 환자에서 특이한 염색체 이상유무를 알고자 자폐장애 환자 29명을 대상으로 하고 질병대조군으로 정신지체 환자 30명을 대상으로 하여, 1) PHA 자극 말초혈 임파구의 G분염에 의한 상용 염색체검사를 실시하여 염색체 이상 유무를 확인하고, 2) MTX를 함유한 배지에서 fragile site 분석을 각각 실시하였다. 연구결과 G 분염에 의한 상용 염색체검사에서는 자폐장애군과 정신지체군에서 모두 46XX 혹은 46XY로서 정상 핵형을 보였으며, fragile site 분석결과에서 fra X(q27.3)은 두 군 모두에서 한 명도 발견되지 않았다. Fragile X 이외의 염색체 이상을 보인 예는 자폐장애군 11명(37.9%), 정신지체군에서 10명(33.3%) 발견되었으나 자폐장애군과 정신지체군 상호간에 유의성 있는 차이는 발견할 수 없었으며, fragile site와 gap이 A, B, C, D, E군에서 다양하게 분포되어 있어 의미있는 분절 부위는 없었다. Fragile site가 관찰된 세포의 수는 자폐장애군에서 31개로 관찰한 모든 중기 세포의 3.6%에 해당하였고 정신지체군에서 29개, 3.2%가 발견되었으며 gap이 관찰된 세포의 수는 자폐장애군에서 43개로 관찰한 모든 중기세포의 4.9%에 해당하였고 정신지체군에서 35개, 3.9%가 발견되었다. 이상의 결과에서, 본 연구에서 조사대상으로 한 자폐장애군에서는 fragile(X)(q27.3)가 한 예에서도 관찰되지 않아, fragile X 증후군에 의한 자폐장애는 매우 드물 것으로 생각되며, fragile X증후군을 자폐장애의 직접적인 원인으로는 생각하기 힘들다. 그리고 자폐장에 환자에서 관찰되는 fragile site와 gap은 정신지체군에서도 비슷한 빈도 및 양상으로 관찰되는 바 자폐장애 환자의 특이한 소견은 아니었다.

To discover genetic markers for autism spectrum disorder (ASD), we previously applied genome-wide BAC array comparative genomic hybridization (array-CGH) to 28 autistic patients and 62 normal controls in Korean population, and identified that chromosomal losses on 8p23.1 and on 17p11.2 are significantly associated with autism. In this study, we developed an 8.5K ASD-specific BAC array covering 27 previously reported ASD-associated CNV loci including ours and examined whether the associations would be replicated in 8 ASD patient cell lines of four different ethnic groups and 10 Korean normal controls. As a result, a CNV-loss on 8p23.1 was found to be significantly more frequent in patients regardless of ethnicity (p<0.0001). This CNV region contains two coding genes, DEFA1 and DEFA3, which are members of DEFENSIN gene family. Two other CNVs on 17p11.2 and Xp22.31 were also distributed differently between ASDs and controls, but not significant (p=0.069 and 0.092, respectively). All the other loci did not show significant association. When these evidences are considered, the association between ASD and CNV of DEFENSIN gene seems worthy of further exploration to elucidate the pathogenesis of ASD. Validation studies with a larger sample size will be required to verify its biological implication.

Purpose: To evaluate the usefulness of the Korean Developmental Screening Test (K-DST) for infants and children for developmental delay assessment. Methods: This study was based on retrospective studies of the results of the K-DST, Preschool Receptive-Expressive Language Scale (PRES), Sequenced Language Scale for Infants (SELSI), Childhood Autism Rating Scale (CARS), Modified Checklist for Autism in Toddlers (M-CHAT), electroencephalography, magnetic resonance imaging, and extensive tests conducted in 209 of 1,403 patients, of whom 758 underwent the K-DST at the Korea University Guro Hospital between January 2015 and December 2016 and 645 were referred from local clinics between January 2015 and June 2016. Results: Based on the K-DST results, the male children significantly more frequently required further or follow-up examination than the female children in most test sections, except for gross motor. The male children had notably lower mean scores than the female children. The PRES/SELSI results showed that when more further or follow-up evaluations were required in the K-DST communication section, significantly more problems in language delay or disorder emerged. When further or follow-up evaluation was required in the cognitive section in the CARS/M-CHAT, the possibility of autism increased significantly. A child tended to score low in the CARS test and show autism when further or follow-up evaluation was recommended in the K-DST. Conclusion: This study demonstrated the usefulness of the K-DST as a screening test early in the development of infants and children in Korea. Data of normal control groups should be examined to determine the accuracy of this investigation.

Background: The results differ among published studies regarding exposure to meconium and the risk of developing autism spectrum disorders (ASDs). Purpose: The present study pooled all of the epidemiologic studies retrieved from broader databases on the association between meconium exposure and risk of developing ASD in children. Methods: The Web of Science, PubMed, Scopus, and Google Scholar databases were searched without language restrictions for articles published between their inception to February 20, 2020, using relevant keywords. The pooled odds ratios (ORs) and their 95% confidence intervals (CIs) were calculated as random-effect estimates of the associations among studies. A subgroup analysis was conducted to explore any potential sources of heterogeneity among studies. Results: The pooled estimate of OR reported a weakly significant association between meconium exposure and ASD development in children (OR, 1.13; 95% CI, 1.03-1.24). There was low heterogeneity among the articles reporting risk for ASD among children (I²=19.3%; P=0.259). The results of subgroup analysis based on meconium exposure showed a significant association between a meconium-stained neonate and ASD development (OR, 1.18; 95% CI, 1.11-1.24). Couclusion: Meconium exposure was weakly associated with an increased risk of ASD. However, more evidence based on large prospective cohort studies is required to provide conclusive evidence about whether meconium exposure is associated with an increased risk of ASD development.

This study examined the eating habits and preferences of foods according to the age of children with autism spectrum disorders and identified the nutritional needs of parents to support their healthy eating habits and provide basic data for the development of educational programs. A survey of 100 parents of children with autism spectrum disorders was conducted on their children's snack intake, food preferences, and parents' nutrition education needs. As a result, there were four times more boys than girls, and the body mass index differed according to age (p<0.001). Most children ate snacks more than once a day, and parents found that they wanted to develop nutritious snacks that could replace high-protein, low-calorie meals with the minimal use of additives. For the food preference, there was a significant difference in grains and starches, vegetables/seafood and fruits, milk and dairy products (p<0.05), fats and sugars, and Korean fermented pastes (p<0.01) between the two age groups. Regarding whether nutrition education was required, many parents had a high demand for nutrition education (4.24±0.70), and the intention to participate was 3.62±1.09. The most important content to be dealt with in parent education was 'Inducing a change in bad eating habits and behaviors', which was the highest (63%), and mostly face-to-face education was preferred. In conclusion, young children require diet education, and older children need to focus on weight control and obesity.

Objectives: The purpose of this study is to investigate the professional knowledge and perceptions of the early screening of Autism Spectrum Disorder (ASD) in practitioners who have contact with patients with ASD. Methods: A survey was carried out among 674 practitioners in total, where practitioners are defined as those who work at primary medical centers, public institutions, educational institutions and treatment institutions. The survey was carried out both online and offline, and it mainly focused on 1) knowledge about ASD symptoms, 2) knowledge about the early screening of ASD, 3) measures taken after ASD detection, 4) thoughts on the development of early screening tools for ASD, and 5) the current status of ASD treatment. The data collected were analyzed through descriptive statistics, analysis of frequency and cross tabulation analysis using SPSS WIN 22.0. Results: The results of this study suggest that the practitioners were not aware of the exact symptoms of ASD and their professional knowledge and the environment for early screening were insufficient. Furthermore, very few and inappropriate measures were taken after the detection of ASD. In addition, there was a high demand for early ASD screening tools to be used on site and, regarding treatment, the significance of the implementation of evidence based treatments as well as the continuity of relevant research came to the fore. Conclusion: It seems that there is a lack of knowledge and perception of the early screening of ASD and that education and training among practitioners is urgently required. This issue is discussed in more detail in the paper.

Objectives: Individuals with autism spectrum disorder (ASD) are considered to have problems with empathy. It has recently been suggested that there are two systems for empathy; cognitive and emotional. We aimed to investigate the neural response to cognitive and emotional empathy and elucidate the neurobiological aspects of empathy in patients with ASD. Methods: We recruited patients with ASD (N=17, ASD group) and healthy controls (HC) (N=22, HC group) for an functional magnetic resonance imaging study. All of the subjects were scanned while performing cognitive and emotional empathy tasks. The differences in brain activation between the groups were assessed by contrasting their neural activity during the tasks. Results: During both tasks, the ASD group showed greater neural activities in the bilateral occipital area compared to the HC group. The ASD group showed more activation in the bilateral precunei only during the emotional empathy task. No brain regions were more activated in the HC group than in the ASD group during the cognitive empathy task. While performing the emotional empathy task, the HC group exhibited greater neural activities in the left middle frontal gyrus and right anterior cingulate gyrus than the ASD group. Conclusion: This study showed that the brain regions associated with cognitive and emotional empathy in ASD patients differed from those in healthy individuals. The results of this study suggest that individuals with ASD might have defects both in cognitive empathy and in emotional empathy.

본 연구는 그룹홈에 거주하는 자폐범주성장애 성인들을 대상으로 진행된 상호적 악기연주 프로그램이 사회적 상호작용 기능 향상에 미치는 효과를 살펴보고자 하였다. 연구참여자는 발달장애 주간보호센터에 소속된 공동생활가정(그룹홈)에 거주하는 20대 후반 자폐범주성장애 1급 성인 남성 3명이다. 단일대상연구설계 중 참여자간 중다기초선설계를 적용하여 총 3개월 동안 각 참여자별로 기초선, 중재, 유지 구간을 포함하여 총 25회기 세션이 실시되었다. 중재효과를 확인하기 위하여 사전에 조작적으로 정의된 상호작용 시도 행동과 반응 행동을 매회 기 촬영된 동영상 자료를 바탕으로 관찰 및 측정하였다. 각 참여자는 음악적 환경 안에서 사회적 상호작용 시도 및 반응 행동 시점을 알려주는 음악구조와 큐에 의해 구조화된 상호적 악기 연주에 참여하였는데, 중재 이후 모든 참여자의 상호작용 시도 행동, 반응 행동 발생률이 증가하는 추세를 보였다. 이러한 결과는 상호적 악기 연주가 자폐범주성장애 성인의 자발적 상호작용 행동을 유도하는 데 효과적인 중재 방법으로 적용될 수 있음을 보여준다. 또한 음악적으로 전달된 사회적 정보가 사회적 맥락 안에서 타그룹원의 의도를 이해하고 사회적 상호작용에 참여하도록 촉진하는 효과적인 매체가 될 수 있음을 시사한다. 향후 자폐범주성장애 성인의 사회성 향상뿐만 아니라 삶의 질 향상을 위한 음악치료 중재가 지속적으로 개발되고 적용될 필요가 있음을 제안하였다.
