A 55-year-old woman was seen in the emergency department with posterior neck pain and a headache after a traffic accident. Physical examination revealed tenderness on palpation over the posterior skull and a midline spinous process of the cervical spine without neurologic deficit. A plain radiograph of the cervical spine demonstrated the absence of the lateral portion of the posterior arch of the atlas and very lucent shadowing of the anterior midline of the atlas, suggesting a fracture of the anterior arch. On three-dimensional computed tomography (CT) of the cervical spine, anterior and posterior bony defects of the atlas were noted. Well-corticated defects were noted with sclerotic change and with no evidence of soft tissue swelling adjacent to the bony discontinuities, consistent with a congenital abnormality. With conservative therapy, the patient gradually showed a lessening of the midline tenderness. Careful investigation with radiography or CT is needed for these patients to avoid confusion with a fracture, because these patients seldom need surgical treatment.

Down syndrome, the most common chromosomal abnormality, may be associated with various neurologic complications such as moyamoya syndrome, cervical spinal cord compression due to atlantoaxial subluxation, and basal ganglia damage, as well as epileptic seizures and stroke. Many cases of Down syndrome accompanied by isolated neurologic manifestations have been reported in children; however, Down syndrome with multiple neurologic conditions is rare. Here, we have reported a case of Down syndrome in a 10-year-old girl who presented with asymptomatic moyamoya syndrome, atlantoaxial subluxation with spinal cord compression, and basal ganglia calcification. To the best of our knowledge, this is the first report of Down syndrome, in a child, which was accompanied by these 3 neurologic complications simultaneously. As seen in this case, patients with Down syndrome may have neurologic conditions without any obvious neurologic symptoms; hence, patients with Down syndrome should be carefully examined for the presence of neurologic conditions.

Purpose: We studied the impact of arterial oxygen tension (PaO₂) on the long term neurologic outcome in patients with acute carbon monoxide poisoning. Methods: The study population included 311 patients who presented to emergency department with acute CO poisoning from January 2015 to January 2018. These patients underwent arterial blood gas testing at the time of presentation. The baseline demographic, clinical, laboratory, and clinical outcome data were recorded. The primary outcome of interest was the long term neurologic status. Results: The normoxia group was significantly older and it had a higher incidence of diffusion weighted MRI abnormality, and this group needed multiple HBO sessions compared to the group with moderate or severe hyperoxia. Also, the incidence of altered mentality at discharge was higher in the normoxia group than that of the moderate hyperoxia group. The incidence of a poor long term neurologic outcome was 11.3%. The incidence of a poor long term neurologic outcome decreased as the PaO₂ increased. The PaO₂ was significantly lower in patients with a poor long term neurologic outcome than that of the patients with a good outcome 198 (165.2 to 231.1) mmHg in the good outcome group vs. 154 (119-162) mmHg in poor outcome, p<0.001). In multivariate logistic regression analysis, PaO₂ was selected as an independent factor of the poor long-term neurologic outcome (OR 0.981 (95% CI: 0.968 to 0.995)) Conclusion: Higher PaO₂ was independently associated with a lower incidence of a poor long-term neurologic outcome.

Purpose: This study aimed to determine new criteria for detecting independent factors with high sensitivity in cases of cervical spine injury. We compared the sensitivity, the specificity, and the false negative predictive value (NPV) of plain radiographs with those of computed tomography for cervical spine injury in patients with minor head injury. Methods: We retrospectively reviewed the cases of 357 patients who underwent both cervical plain radiographs and computer tomography from January 2006, to September 2008. Patients were divided into two groups: the cervical spine injury group and the no cervical spine injury group. New criteria were organized based on variables that had significant differences in the logistic regression test. Results: Among the 357 patients, 78 patients had cervical spine injuries. The average age was $43.9{\pm}15.2$ yrs old, and the male-to-female ratio was 1.90. The most common mechanism of injury was motor vehicle accidents. There was a significant difference in loss of consciousness, Glasgow Coma Scale (GCS)=14, neurologic deficit, posterior neck tenderness, and abnormality of the cervical plain radiographs between the two groups on the logistic regression test. New criteria included the above five variables. If a patient has at least variable, the area under the ROC curve of the new criteria was 0.850, and the sensitivity and the false NPV were 87.2% and 5.2%, respectively. Conclusion: New criteria included loss of consciousness, GCS=14, neurologic deficit, posterior neck tenderness, and abnormality of the cervical plain radiographs. If the patient had at least 1 variable, he or she could have a of cervical spine injury with a sensitivity of 87.2% and a false NPV of 5.2%.

배경: 최근 관상동맥 우회수술의 조기 성적이 향상됨에 따라 뇌 경색을 비롯한 신경계 합병증이 수술 후 경과를 결정하는 중요한 합병증으로서 비중이 증가하고 있다. 이에 본 연구에서는 관상동맥 우회수술 후에 발생하는 신경계 합병증의 발생 양상을 분석하고 그 위험인자를 규명하고자 하였다. 대상 및 방법: 관상동맥 우회수술을 시행받은 351명의 환자를 대상으로 신경계 합병증의 발생 여부와 형태, 위험인자를 분석하였다. 신경계 합병증은 새로운 뇌 경색이 확진된 경우와 수술후 의식 및 지남력의 완전한 회복이 24시간 이상 지연된 경우로 정의하였다. 결과: 대상 환자중 18명(5.1%)에서 신경계 합병증이 발생하였으며 그 중 뇌 경색이 확진된 환자는 9명(2.6%)이었다. 운동마비를 동반한 뇌 경색이 4명에서 발생하였고 4명은 정신 지체나 지남력 장애의 형태로 나타났으며 뇌사 판정을 받은 환자가 1명 있었다. 나머지 9명은 뇌 경색의 증거는 발견되지 않았으나 의식 및 지남력의 완전 회복이 지연된 환자들이었다. 통계적 분석 결과 180분 이상의 심폐 바이패스, 수술중 상행 대동맥의 죽상경화반이 진단된 경우, 초음파 검사로 진단된 경동맥 협착, 뇌졸중이나 일과성 뇌허혈의 과거력 등이 단변량 및 다변량 분석 모두에서 의미있는 위험인자로 분석되었다. 그밖에 고령(65세 이상), 흉부 단순 촬영상 대동맥의 석회화가 발견된 경우, 수술중 심근 경색 등도 단변량 분석시 의미있는 위험인자였다. 대동맥궁 삽관이나 single clamp technique 등 신경학적 합병증의 예방에 기여할 것으로 기대되었던 수술 수기상의 변형은 합병증 발생 빈도에 별다른 영향을 미치지 않은 것으로 분석되었으며 경동맥 협착의 정도 역시 합병증 발생 빈도와 상관관계가 없었다. 결론: 이상의 결과로 관상동맥 우회수술 후의 신경계 합병증의 발생 원인은 복합적이긴 하지만 근본적으로는 동맥계의 동맥경화성 병변과 밀접한 관계가 있음을 확인하였다. 따라서 합병증의 예방을 위해서는 수술전 동맥경화성 병변에 대한 전신적인 평가와 함께 고위험군 환자들의 경우 적극적인 수술 수기의 변형을 검토할 필요가 있다고 판단된다.

Hypoglossal neurilemmoma is extremely rare. Intracranial hypoglossal neurilemmoma has been reported to the present most commonly as a space-occupying lesion with symptoms of raised intracranial pressure. A 68-year-old women presented with deviation of the tongue to the left on protrusion. Preoperative radiological images revealed an extra-axial mass in and around the hypoglossal canal. The tumor was totally resected via retrosigmoid suboccipital approach with burrhole craniectomy. Histopathological examination verified a neurilemmoma. She had no neurologic abnormality except hypoglossal palsy which recovered completely in six months. Retrosigmoid suboccipital approach with burrhole craniectomy can be an useful approach in intracranial hypoglossal neurilemmoma without extracranial extension or with minimal extracranial extension into the hypoglossal canal.

Forestier's disease is a systemic rheumatological abnormality in which exuberant ossification occurs along ligaments throughout the body, but most notably the anterior longitudinal ligament of the spine. This disease is usually asymptomatic; however dysphagia, dyspnea, and peripheral nerve entrapment have all been documented in association with the disorder. We report a rare case of catastrophic neurologic damage caused by Forestier's disease accompanying ossification of the posterior longitudinal ligament.

Functional urinary incontinence, the absence of any neurologic or structural abnormality as a cause of urinary incontinence in children, is one of the most common clinical problems encountered in pediatric and urologic departments, and it can be socially and emotionally distressing for the affected children. The prevalence rates of functional urinary incontinence in school-aged children are not very high and differ between boys and girls. The underlying mechanisms of functional urinary incontinence are heterogenous and can be associated with the following dysfunctions of both the storage and voiding patterns of the bladder: overactive bladder, dysfunctional voiding, lazy bladder syndrome, HinmanAllen syndrome, giggle incontinence, and vaginal voiding. Treatment methods for urinary incontinence in children should be chosen according to these clinical conditions. Treatment modalities generally consist of the treatment of comorbid conditions such as urinary infection and constipation, behavior therapy to modify learned voiding patterns, and pharmacotherapy primarily with anticholinergics and ${\alpha}$-adrenergic blockers. This review discusses the optimal treatment modalities, including treatment of the underlying voiding disorders, and diagnostic approaches related to functional urinary incontinence in children.

Transient magnetic resonance (MR) signal changes in the splenium of the corpus callosum (SCC) arise from many different conditions, including encephalopathy or encephalitis caused by infection, seizures, metabolic derangements, and asphyxia. Few case reports exist on reversible SCC lesions associated with rotavirus infection. A benign convulsion with mild gastroenteritis (CwG) is frequently associated with rotaviral infections. This entity is characterized by normal laboratory findings, electroencephalogram, neuroimaging, and good prognosis. We report a case of a 2.5-year-old Korean girl with rotavirus-associated CwG demonstrating a reversible SCC lesion on diffusion-weighted MR images. She developed 2 episodes of brief generalized tonic-clonic seizure with mild acute gastroenteritis without any other neurologic abnormality. Stool test for rotavirus antigen was positive. Brain MRI done on the day of admission showed a linear high signal intensity and decreased apparent diffusion coefficient values on the SCC. The lesion completely disappeared on follow-up MRI 6 days later. The patient fully recovered without any sequelae.
