  • A 4-month-old boy diagnosed with acute myocarditis was treated with extracorporeal membrane oxygenation (ECMO). Follow-up echocardiography eight hours after ECMO revealed intracardiac thrombosis involving all four heart chambers. Because of the high risk of systemic embolization due to a pedunculated thrombus of the aortic valve, we performed an emergency thrombectomy. After the operation, the patient had a minor neurologic sequela of left upper arm hypertonia, which had almost disappeared at the last outpatient clinic two months later. He was diagnosed with a major mutation in MTHFR (methylenetetrahydrofolate reductase), which is related to thrombosis.

  • Recent advances in the diagnosis and treatment of inborn errors of metabolism have improved substantially the prognosis of many of these diseases, if diagnosed early enough before irreversible damage occurs. This makes it essential that the practicing pediatrician, especially neonatologists be familliar with the clinical presentations and systematic approaches of these disorders. Characteristic clinical presentations, methods of systematic approach and typing of various disorders is discussed in this review. The signs of neurological dysfunctions of many IEMs manifesting in the neonatal period is very nonspecific, such as poor feeding, poor sucking, apnea or tachypnea, vomiting, hypertonia, hypotonia, seizure, letharginess, consciousness change and coma. Many other non-metabolic severe disorders of neonatal period such as neonatal sepsis and intracerebral hemorrhage share these nonspecific symptoms. Hyperammonemia, metabolic acidosis, ketosis and hyperlatic acidemia are observed in many of these conditions but there are exceptions in which conditions all basal laboratory tests are normal, such as NKH, sulfite oxidase deficiency and peroxisomal disorders. According to the results of basal laboratory tests, IEMs in the neonatal period can be categorized in to 6 types. Grouping of IEMs into 6 types will make confirmatory tests and early emergency treatment more efficient.

  • Short-chain acyl-CoA dehydrogenase deficiency (SCADD; OMIM # 201470) is an autosomal recessive inborn error of mitochondrial fatty acid ${\beta}$-oxidation, presenting with a variety of clinical signs and symptoms. Developmental delay, hypertonia or hypotonia, ketotic hypoglycemia, and epilepsy are most frequently reported. In general, patients diagnosed through newborn screening have shown normal growth and development in contrast to those diagnosed as a result of clinically initiated evaluations. Here, the case of an asymptomatic Korean newborn with SCADD identified by tandem mass spectrometry is reported. The patient showed an elevated concentration of butyrylcarnitine detected on newborn screening. Urinary excretion of ethylmalonic acid was elevated by urine organic acid analysis. To confirm the diagnosis of SCADD, a direct sequencing analysis of 10 coding exons and the exon-intron boundaries of the ACADS gene were performed. Genetic analysis of ACADS showed the following novel compound heterozygous missense mutations: c.277C>A (p.Leu93Ile) on exon3 and c.682G>A (p.Glu288Lys) on exon6. These results will provide further evidence of mutational heterogeneity for SCADD.

  • 유전성대사장애질환의 진단과 치료는 최근들어 비약적인 발전을 하고 있으며, 치료가 불가능하여 대증적인 치료만이 가능하였던 많은 병들이 치료가 가능하 여지고 있다. 이러한 사실은 비가역적인 후유증이 생기기전의 조기진단의 중요성을 더 크게 한다. 유전성 대사장애질환은 현재 밝혀진 것만 하더라도 수백 가지의 질병에 이르며, 가까운 미래에 그 수는 수천에 이를 것으로 전망되고 있다. 이와 같은 질병의 다양성과 그 증상 및 임상적발현의 다양성은 임상의들이 정확한 진단에 이르는데 크나큰 장애요인이 되고 있다. 신생아기와 영아기 초기의 임상적인 발현은 비특이적이지만 나이가 들어가면서 다양한 특징적인 증상을 나타내게 된다. 같은 질병일지라도 잔류효소농도(residual enzyme activity)가 거의 없는 경우에는 신생아기 또는 영아기 등 이른시기에 증상이 나타나지만 잔류효소농도가 어느 정도 남아 있는 경우에는 늦게 소아기 또는 성인기에 증상을 나타내며, 유기산이나 지방산대사이상의 경우에는 이화작용이 증가되는 스트레스상태에서 갑작스런 악화를 보일 수도 있다. 본 논문에서는 이러한 다양한 증상과 검사소견들을 정리하여 보고, 그러한 증상을 일으키는 주된 질병들을 정리하여 감별진단과 검사를 체계적으로 접근할 수 있도록 하였다.
