  • Background: Scalding burn injuries can occur in everyday life but occur more frequently in young children. Therefore, it is important to develop more effective burn treatments. Objectives: This study examined the effects of bee venom (BV) stimulation on scalding burn injury-induced nociception in mice as a new treatment for burn pain. Methods: To develop a burn injury model, the right hind paw was immersed temporarily in hot water (65℃, 3 seconds). Immediately after the burn, BV (0.01, 0.02, or 0.1 mg/kg) was injected subcutaneously into the ipsilateral knee area once daily for 14 days. A von Frey test was performed to assess the nociceptive response, and the altered walking parameters were evaluated using an automated gait analysis system. In addition, the peripheral and central expression changes in substance P (Sub P) were measured in the dorsal root ganglion and spinal cord by immunofluorescence. Results: Repeated BV treatment at the 2 higher doses used in this study (0.02 and 0.1 mg/kg) alleviated the pain responses remarkably and recovered the gait performances to the level of acetaminophen (200 mg/kg, intraperitoneal, once daily), which used as the positive control group. Moreover, BV stimulation had an inhibitory effect on the increased expression of Sub P in the peripheral and central nervous systems by a burn injury. Conclusions: These results suggest that a peripheral BV treatment may have positive potency in treating burn-induced pain.

  • Hypoxic ischemic encephalopathy (HIE) is an important cause of permanent damage to central nervous system cells, most cases with oxygen deprivation in the nenonate due to birth asphyxia. Survival children with HIE develop problems such as cerebral palsy, mental retardation, learning difficulties, and other permanent neuro-developmental disabilities. This article report two cases of the children with HIE who had be traumatized on their teeth from oropharyngeal airway (OPA) in the emergency situation. The patients with the disease accompanying seizure or convulsion, needs special consideration for the prevention from dental trauma in emergency airway management.

  • Objective : The indications and optimal surgical treatments for intracranial cysts are controversial. In the present study, we describe long-term clinical and neuroimaging results of surgically treated intracranial cysts in children. The goal of this study is to contribute to the discussion of the debate. Methods : This study included 110 pediatric patients that underwent surgeries to treat intracranial cysts. Endoscopic cyst fenestrations were performed in 71 cases, while craniotomies and cyst excisions (with or without fenestrations) were performed in 30 patients. Cystoperitoneal shunts were necessary for nine patients. Long-term results were retrospectively assessed with medical and neuroimaging records. Results : Clinical and radiological improvement was reported in 87.3% and 92.8% of cases, respectively, after endoscopic neurosurgery, and in 93.3% and 100% using open microsurgery whereas 88.9% and 85.7% after shunt operation. There were no statistical differences in clinical outcomes (p=0.710) or volume reductions (p=0.177) among the different surgeries. There were no mortalities or permanent morbidities, but complications such as shunt malfunctions, infections, and subdural hematomas were observed in 56% of the patients that had shunt operations. A total of 13 patients (11.8%) underwent additional surgeries due to recurrences or treatment failures. The type of surgery performed did not influence the recurrence rate (p=0.662) or the failure rate (p=0.247). Conclusion : Endoscopic neurosurgeries are less invasive than microsurgeries and are at least as effective as open surgeries. Thus, given the advantages and complications of these surgical techniques, we suggest that endoscopic fenestration should be the first treatment attempted in children with intracranial cysts.

  • 목 적 : 급성 증후성 경련이란 일시적인 중추 신경계 또는 전신적인 병태생리의 변화와 밀접히 연관되어 발생하는 경련으로 이와 달리 특별한 유발 인자 없이 발생하는 경련은 비유발성 경련으로 분류한다. 급성 증후성 경련이 추후에 비유발성 경련으로 이행할 수 있다는 문헌은 다수 보고되고 있으나 증후성 경련에서 비유발성 경련의 이행에 영향을 미치는 관련 인자들에 대한 자료는 미비한 실정이다. 이에 본 논문에서는 증후성 경련으로 입원한 환아들을 대상으로 지속적인 추적 관찰을 통해 비유발성 경련과 관련된 인자들에 대해 후향적으로 조사하였고, 이러한 관련 인자들과 비유발성 경련 이행 여부에 관해 통계적인 분석을 통해 그 유의성을 알아보고자 하였다. 방 법 : 급성 증후성 경련으로 진단된 환아들을 대상으로 최소 1년간의 추적 관찰을 통해 비유발성 경련으로의 이행 여부를 후향적으로 조사하였고, 이에 따른 관련 인자로써 호발 연령, 성별, 가족력, 경련의 유형, 발달 정도 등을 포함하여 다양한 원인들을 분류하고 뇌파 검사 및 뇌영상 검사 등의 결과를 조사하여 비유발성 경련과의 관계를 통계적으로 분석하였다. 결 과 : 급성 증후성 경련에서 비유발성 경련으로 이행하는 경우는 2-6세에 가장 호발하고 성별에 따른 차이는 없으며 뇌증과 중추 신경계 감염이 많은 원인을 차지한다. 비유발성 경련으로 이행하는 경우의 관련 인자로는 간질 지속 상태를 동반한 경우와 부분 발작의 경우에 통계적으로 유의한 차이를 보이며, 이외에 뇌파 검사와 뇌 영상검사에서 이상 소견을 보이는 경우에도 비유발성 경련으로 이행하는 데 있어 통계적으로 유의한 값을 보였다. 그러나 성별, 경련성 질환의 가족력, 발달 정도, 경련시의 각성 상태 등의 인자들과 비유발성 경련의 관계에는 통계적인 유의성을 갖지 못하였다. 결 론 : 급성 증후성 경련 환아들의 비유발성 경련 이행에 따른 관련 인자로는 경련의 지속 시간, 경련의 유형, 이상 뇌파 소견 및 이상 뇌 영상검사 소견을 들 수 있다. 따라서 이러한 인자들에 해당하는 경우에는 급성 증후성 경련의 치료 후에도 지속적인 추적 관찰을 통해 향후 발생할 수 있는 비유발성 경련에 대한 적절한 검사와 대처가 필요하다고 생각된다.

  • Reports of constitutional ring chromosome 22, r(22) are rare. Individuals with r(22) present similar features as those with the 22q13 deletion syndrome. The instability in the ring chromosome contributes to the development of variable phenotypes. Central nervous system (CNS) atypical teratoid rhabdoid tumors (ATRTs) are rare, highly malignant tumors, primarily occurring in young children below 3 years of age. The majority of ATRT cases display genetic alterations of SMARCB1 (INI1/hSNF5 ), a tumor suppressor gene located on 22q11.2. The coexistence of a CNS ATRT in a child with a r(22) is rare. We present a case of a 4-month-old boy with 46,XY,r(22)(p13q13.3), generalized hypotonia and delayed development. High-resolution microarray analysis revealed a 3.5-Mb deletion at 22q13.31q13.33. At 11 months, the patient had an ATRT ($5.6cm{\times}5.0cm{\times}7.6cm$) in the cerebellar vermis, which was detected in the brain via magnetic resonance imaging.

  • Inherited metabolic disorders are individually rare but as a whole, they are nor rare. Since Archibald Garrod introduced a concept of "inborn error of metabolism" or "chemical individuality", more than 500 diseases are currently known, affecting approximately one in 500 newborns cumulatively. They frequently manifest with acute, life-threatening crisis that require immediate specific intervention or they present with insidious diverse symptoms and signs involving multiple visceral organs or tissues as well as central nervous system, hampering a correct diagnosis. In addition, many pediatricians are not familiar with all diagnostic and therapeutic strategies for diverse inherited metabolic disorders. However, the prognosis of affected children are heavily dependent on rapid and effective treatment. In this lecture, practical guidelines for the specific diagnosis based on diverse clinical features of inherited metabolic disorders will be described. Many sophisticated laboratory tests are available for confirmatory diagnosis of each disease, which challenge to general pediatricians with respect to knowledge about biochemical metabolite assay test, enzymatic test and DNA diagnostic tests. Sample collections, indications, methods and interpretation of results in varying laboratory tests will be listed as well.

  • Primary malignant leptomeningeal melanoma is very rare, accounting for less than 0.1 percent of tumors in the central nervous system. Patients with primary intracranial malignant melanoma tend to be younger than metastatic intracranial melanoma, most commonly in the fourth decade of life. This tumor is extremely rare and the biologic behavior is aggressive especially in children. The authors report a case of primary malignant leptomeningeal melanoma in a twelve-year-old boy which was initially diagnosed as meningitis. On autopsy, associated extensive leptomeningeal melanosis was confirmed and believed to be the origin of the tumor. This case emphasizes the pattern of clinical presentation and the significance of leptomeningeal melanosis in primary leptomeningeal melanoma.

  • Pelizaeus-Merzbacher disease (PMD) can be defined as an X-linked recessive leukodystrophy that is caused by a mutation in the proteolipid protein gene on chromosome Xq22. PMD is one of a group of progressive, degenerative disorders of the cerebral white matter known as the leukodystrophies. Due to the progressive nature of the disorders and their devastating effects on the central nervous system, these children frequently require anesthesia during imaging procedures such as MRI or during various surgical procedures. Anesthetic concerns in theses cases include high prevalence of seizure disorders, gastroesophageal reflux with the risk of aspiration, airway complications related to poor pharyngeal muscle control and copious oral secretions, and mental retardation. We report a successful anesthetic management in a patient with PMD for dental procedures.

  • Cytomegalovirus (CMV) is currently the most common agent of congenital infection and the leading infectious cause of brain damage and hearing loss in children. Symptomatic congenital CMV infections usually result from maternal primary infection during early pregnancy. One half of symptomatic infants have cytomegalic inclusion disease (CID), which is characterized by involvement of multiple organs, in particular, the reticuloendothelial and central nervous system (CNS). Moreover, such involvement may or may not include ocular and auditory damage. Approximately 90% of infants with congenital infection are asymptomatic at birth. Preterm infants with perinatal CMV infection can have symptomatic diseases such as pneumonia, hepatitis, and thrombocytopenia. Microcephaly and abnormal neuroradiologic imaging are associated with a poor prognosis. Hearing loss may occur in both symptomatic and asymptomatic infants with congenital infection and may progress through childhood. Congenital infection is defined by the isolation of CMV from infants within the first 3 weeks of life. Ganciclovir therapy can be considered for infants with symptomatic congenital CMV infection involving the CNS. Pregnant women of seronegative state should be counseled on the importance of good hand washing and other control measures to prevent CMV infection. Heat treatment of infected breast milk at $72{^{\circ}C}$ for 5 seconds can eliminate CMV completely.
