  • Channelopathies are a heterogeneous group of disorders resulting from the dysfunction of ion channels located in the membranes of all cells and many cellular organelles. These include diseases of the nervous system (e.g., generalized epilepsy with febrile seizures plus, familial hemiplegic migraine, episodic ataxia, and hyperkalemic and hypokalemic periodic paralysis), the cardiovascular system (e.g., long QT syndrome, short QT syndrome, Brugada syndrome, and catecholaminergic polymorphic ventricular tachycardia), the respiratory system (e.g., cystic fibrosis), the endocrine system (e.g., neonatal diabetes mellitus, familial hyperinsulinemic hypoglycemia, thyrotoxic hypokalemic periodic paralysis, and familial hyperaldosteronism), the urinary system (e.g., Bartter syndrome, nephrogenic diabetes insipidus, autosomal-dominant polycystic kidney disease, and hypomagnesemia with secondary hypocalcemia), and the immune system (e.g., myasthenia gravis, neuromyelitis optica, Isaac syndrome, and anti-NMDA [N-methyl-D-aspartate] receptor encephalitis). The field of channelopathies is expanding rapidly, as is the utility of molecular-genetic and electrophysiological studies. This review provides a brief overview and update of channelopathies, with a focus on recent advances in the pathophysiological mechanisms that may help clinicians better understand, diagnose, and develop treatments for these diseases.

  • Purpose: This study aimed to evaluate the clinical findings in pediatric rhabdomyolysis and the predictive factors for acute kidney injury (AKI) in Korean children. Methods: Medical records of 39 Korean children, who were newly diagnosed with rhabdomyolysis from January 2008 to December 2015, were retrospectively analyzed. The diagnosis was made from the medical history, elevated serum creatinine kinase level >1,000 IU/L, and plasma myoglobin level >150 ng/mL. Patients with muscular dystrophy and myocardial infarction were excluded. Results: The median patient age at diagnosis was 14.0 years (range, 3-18 years), and the male to female ratio was 2.5. The most common presenting symptom was myalgia (n=25, 64.1%), and 14 patients (35.9%) had rhabdomyolysis-induced AKI. Eighteen patients (46.2%) had underlying diseases, such as epilepsy and psychotic disorders. Ten of these patients showed rhabdomyolysis-induced AKI. The common causes of rhabdomyolysis were infection (n=12, 30.7%), exercise (n=9, 23.1%), and trauma (n=8, 20.5%). There was no difference in the distribution of etiology between AKI and non-AKI groups. Five patients in the AKI group showed complete recovery of renal function after stopping renal replacement therapy. The median length of hospitalization was 7.0 days, and no mortality was reported. Compared with the non-AKI group, the AKI group showed higher levels of peak creatinine kinase and myoglobin, without statistical significance. Conclusion: The clinical characteristics of pediatric rhabdomyolysis differ from those observed in adult patients. Children with underlying diseases are more vulnerable to rhabdomyolysis-induced AKI. AKI more likely develops in the presence of a high degree of albuminuria.

  • The purpose of this study were to identify the quality of life for the mothers of hospitalized chronic pediatric patients, and to explore the factors affecting the QOL of those mothers. The subjects were 201 mothers whose children had hospitalized at one University hospital with chronic diseases. Data were collected from the December, 1997 to December, 1998. We used a revised QOL instrument consisting of 34 items, 5 point likert scale based on the Noh's QOL instrument. The revised QOL consists of six subscales, those are physical status and function, self esteem, emotional status, economic status, relationship with family members, and relationship with neighborhood. Data were analyzed by t-test, ANOVA, Pearson's correlation using SPSS-PC. The results were as follows: 1. The mean score of quality of life for the mothers of chronic pediatric patients was 100.31, and item mean was 2.95. In subscale analysis, item mean of economic status was the lowest, and that of relationship with family members was the highest. 2. Correlations between characteristics of chronic pediatric patients, their mothers and QOL of mothers were as follows; 1) Total QOL of mothers had a significant positive relationship with progressing time relapse after diagnosing and age of mothers. There was a significant negative relationship between the total QOL of mothers and number of hospitalization of their children. 2) QOL on self esteem and economic status had a significant relationship with age of pediatric patients, the time relapse after diagnosis, and age of mothers. Total number of family members and QOL on economic status showed a significant positive relationship. QOL on emotional status, economic status, and relationship with family members of mothers showed negative correlations with the number of hospitalization of their children. 3. Followings were the result of difference in QOL among different demographic cha- racteristics of the subjects. 1) QOL on economic status of mothers was significantly higher when fathers of pediatric patients had jobs. 2) Total QOL score, QOL on emotional status, and QOL on relationship with neighborhood were significantly higher when mothers of pediatric patients had spouses. 3) QOL on self esteem of mothers was significantly higher when mothers had religion. 4. Followings were the result of difference in QOL among different diagnosis of the children. 1) Total QOL score of mothers whose children had congenital heart disease was higher than that of mothers whose children had leukemia and cancer. 2) QOL on emotional status, economic status, and relationship with family members of mothers whose children had congenital heart disease were higher than those of mothers whose children had leukemia, cancer, and epilepsy.

  • 목 적 : 뇌실 주위 백질연화증(periventricular leukomalacia)은 동맥혈의 허혈로 인하여 뇌실 주변에 백질 괴사가 초래되어 발생하는 질환으로 미숙아와 만삭아 모두에서 관찰될 수 있으며 간질 발생의 요인이 된다. 본 연구는 뇌실 주위 백질연화증이 관찰된 간질 환아에서 재태 연령에 따라 간질 발작의 임상적인 차이점이 있는지 알아보고자 시행되었다. 방 법 : 뇌 자기공명영상으로 뇌실 주변부에 T2 강조 영상으로 고신호강도의 병변이 관찰된 108례(미숙아군 79례, 만삭아군 29례) 중 2회 이상의 간질 발작을 보이고 6개월 이상 추적 관찰이 가능했던 37례를 연구 대상으로 하였으며, 이를 다시 재태 기간이 37주 미만의 미숙아군(27례)과 37주 이상의 만삭아군(10례)으로 나누어 두 군을 비교하였다. 각각의 증례별 병력 기록지를 조사하여 두 군간의 간질 발작의 초발 연령, 첫 간질 발작의 유형, 뇌파 소견 및 항경련제에 대한 치료 반응을 비교하는 후향적 연구를 하였다. 결 과 : 첫 간질 발작은 미숙아군의 경우 평균 $22.2{\pm}18.3$개월, 만삭아군의 경우에는 평균 $26.9{\pm}21.1$개월에서 시작되었으며 통계학적으로 유의한 차이는 없었다(P=0.505). 첫 간질 발작의 유형으로는 미숙아군의 경우 영아 연축이 11례(40.7%), 단순 또는 복잡 부분 발작이 7례(25.9%), 이차성 전범화의 부분 발작이 6례(22.2%), 그리고 전신성 발작이 3례의 순으로 많았다. 만삭아군에서는 단순 또는 복잡 부분 발작이 7례(70.0%), 전신성 발작이 2례(20.0%) 그리고 지발형 영아 연축이 1례(10.0%)의 순으로 많았다. 뇌파 소견으로 미숙아군에서 고부정 뇌파가 11례(40.7%), 국소성 간질파가 6례(22.2%), 다초점성 간질파가 4례(14.8%)의 순으로 많았고, 만삭아군에서는 국소성 간질파가 5례(50.0%)였으며 3례(30.0%)에서 간질파가 관찰되지 않았다. 항경련제에 대한 반응은 추적 관찰 기간 동안 간질 발작의 재발을 보이지 않았던 경우가 미숙아군은 27례 중 16례(59.3%), 만삭아군의 경우 10례 중 6례(60.0%)였으며 난치성 간질은 미숙아군에서 6례(22.2%)가 있었으나 만삭아군에서는 1례도 관찰되지 않았다. 결 론 : 뇌실 주위 백질연화증을 가진 간질 환아에서 영아 연축과 같은 중증 간질은 미숙아군에서 주로 발생하는 경향이 있었으며 난치성 간질은 미숙아군에서만 관찰되어 만삭아군과 임상적으로 간질 발작의 유형이나 치료에 대한 반응 등에서 차이가 있는 것으로 생각된다. 향후 뇌실 주위 백질연화증의 정도나 발생 기전에 대해 두 군간의 차이점이 있는지에 대한 연구가 두 군간의 간질 발작의 임상적 차이를 이해하는데 도움이 될 것으로 생각된다.

  • Objectives : To study the pediatric contents in the 『Maijing』, the most comprehensive compilation of pulse theory. Methods : First, the original meaning was understood comprehensively through careful translation of the original text. Next, the original texts from which 『Maijing』 quoted certain verses were traced. Then, contents of 『Maijing』 were analyzed through comparison with contents from later period texts such as 『Beijiqianjinyaofang』, 『Zhubingyuanhoulun』, 『Xiaoeryaozhengzhijue』, 『Zhengzhizhunsheng』. Results : The study of pediatric contents of Wangshuhe's 『Maijing·Chapter9·Determining Pediatric Diseases 9th』 revealed that he set the standards of 'normal pulse' in terms of number of pulsation and pulse xiang[脈象] differently for children compared to adults. He summarized the most common disease patterns to be wind epilepsy[風癎], indigestion of breast milk[乳不消], and fright seizure[客忤氣], and described the pulses that reflected these conditions's physical characteristics. He also described the pulse and symptom patterns of 'growth fever[變蒸]' and 'heat in bone part[骨間有熱]' based on his observation, which contents were quoted and developed in 『Zhubingyuanhoulun』 and 『Xiaoeryaozhengzhijue』. For other miscellaneous pediatric conditions, he quoted prior texts such as 『Lingshu』 while adding words or making modifications to better reflect characteristics of children based on his observations in clinical pediatrics. Conclusions : It is concluded that 『Maijing·Chapter9·Determining Pediatric Diseases 9th』 not only describes pulse diagnostics but reflects in its contents pediatric theories and clinical knowledge of the Jin(晉)period, which affected pediatrics development of following periods.

  • Meningioangiomatosis (MA) is a rare congenital tumor that occurs mostly in 5-15 year old children. There have been only 5 cases previously reported that described the cystic nature within these tumors. We present a case of a MA accompanied by a separate macrocyst. A normally developed 2 year-old female patient presented with partial and generalized seizures. The brain computerized tomogram and magnetic resonance imaging revealed the presence of a calcified mass accompanied by a cyst in the right parietal area, surrounded by low density and high attenuation edema and hemorrhage. Upon right parietal craniotomy, a $1.6cm{\times}1.2cm{\times}0.5cm$ sized plate-like, gray-white, slightly hard mass was seen and it was completely excised. Approximately 1 cm from the mass in the anterior lateral direction, a cyst was found and subsequent biopsy of the cyst wall revealed no tumor tissue, and therefore the cyst was not removed. Pathologic report demonstrated the meningioangiomatosis. Follow up examination 2 years later showed no recurrence of the tumor, and there was no evidence of neurological deficits. Authors suggest that cysts that arise in the surrounding tissues of tumors may not be tumor cysts, and do not require surgical removal.

  • 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.

  • 외상성 뇌손상(traumatic brain injury, TBI)은 다양한 외부요인에 의해 나타나는 직접적인 뇌조직 손상으로, 변성된 뇌신경세포의 지연성 병태생리학적인 변화를 수반하는 질환으로 잘 알려져 있다. 이러한 뇌손상은 그 정도에 따라 인지기능저하 및 운동능력의 손상을 야기하는 것으로 알려져 있으며, 특히, 일부 환자에서는 뇌손상 후유증으로 회귀성 간질발작 증상이 나타나는 것으로 알려 있다. 외상성 뇌손상 후 간질발생기전에 대한 연구에서 GABAergic interneurons의 손상과 다양한 종류의 억제성 사이신경의 작용이 간질질환의 발병에 매우 중요한 역할을 하는 것으로 알려져 있다. 따라서, 본 연구에서는 외상성 뇌손상 후 초기단계에서 칼슘결합단백질이 발현되는 GABAergic interneurons의 면역반응성이 어떠한 변화를 나타내는지를 분석하고, 이와 같은 발현변화가 외상성 손상 후 간질발생 및 전파에 미치는 영향을 분석하여 이들 사이의 연관성을 규명하기 위하여 연구를 수행하였다. 연구결과 극저온으로 외상성 뇌손상을 주었을 때 극저온 손상에 노출된 대뇌의 해마에서 parvalbumin (PV) 및 calbindin D-28k (CB)와 같은 칼슘결합단백질의 발현이 시간경과에 따라 다양하게 변화되는 것을 확인 할 수 있었다. 극저온에 노출되어 손상을 받은 부위는 뇌손상 후 30분경에 대조군에 비해 PV 및 CB의 발현이 현저하게 감소하였으며, 이들에 면역반응성을 나타내는 신경세포의 숫자도 시간경과에 따라 감소하였으나, 시간이 경과함에 따라 정상수준으로 회복되었다. 그러나, 외상성 뇌손상에 노출되지 않은 반대측 해마에서는 CB의 면역반응성에는 특이한 변화가 없는 반면, PV의 발현은 뇌손상 후 1일 이후부터 대조군에 비해 특이하게 감소하였다. 따라서, 이 실험의 결과는 뇌손상후 해마에서 나타나는 칼슘결합단백질의 감소가 $GABA_A$ receptor를 통한 억제성신경전달의 감소에 관여하고, 이러한 작용에 의해 일시적으로 해마내 신경세포들의 과흥분성 신경전달이 증가하는 것으로 생각된다. 또한, 외상성 뇌손상에 노출되지 않은 반대측 해마에서 나타나는 PV 면역반응 신경세포의 감소는 외상성 뇌손상에 노출된 동측 해마에서 나타나는 칼슘결합단백질의 변화와 함께 외상성 뇌손상 후 간질발생에 중요한 역할을 할 것으로 생각된다.
