Human sparganosis is a zoonotic disease caused by infection and migration of the plerocercoid of Spirometra spp. Although sparganosis were reported from most parts of the body, the sparganum parasitizing inside cerebral artery is remarkably uncommon. We report a case of cerebral intravascular sparganosis in an elderly patient with acute ischemic stroke who was diagnosed by retrieving sparganum during mechanical thrombectomy. Finally, the parasites were identi- fied as Spirometra erinaceieuropaei using multiplex PCR and cox1 gene sequencing.

Background and Purpose The outcome for older stroke patients who undergo endovascular revascularization remains unsatisfactory. We aimed to determine the effect of the extent of baseline ischemia on outcome according to age, testing the hypothesis that the restorative capacity for recovery is only marginal in older patients. Methods Two hundred and thirteen patients who underwent endovascular revascularization due to occlusion in the M1 segment of the middle cerebral artery (with or without internal carotid artery occlusions) were selected for analysis. Patients were categorized into three age groups: group A (<66 years), group B (66–75 years), and group C (>75 years). Using pretreatment diffusion-weighted imaging (DWI), the Alberta Stroke Program Early CT Score (ASPECTS) and lesion volume were independently measured and analyzed in relation to a favorable outcome. Results A favorable outcome was achieved in 111 of 213 patients overall: in 60 of the 94 (63.8%) patients in group A, in 36 of the 70 (51.4%) patients in group B, and in 15 of the 49 (30.6%) patients in group C (p=0.001). In older stroke patients (group C), a DWI ASPECTS ≥9 and lesion volume ≤5 mL were found to predict a favorable outcome, which was more restrictive than the cutoffs for their younger counterparts (groups A and B; DWI ASPECTS ≥8 and lesion volume ≤20 mL). Conclusions The age-adjusted pretreatment DWI lesion volume and ASPECTS may represent useful surrogate markers for functional outcome according to age. The use of more-restrictive inclusion criteria for older stroke patients could be warranted, although larger studies are necessary to confirm these findings.
Cognitive Impairment in Juvenile Myoclonic Epilepsy

Background and Purpose: Cognitive impairments are frequent consequences of epilepsy, with intellectual ability reportedly being lower in patients with idiopathic generalized epilepsies than in the general population. However, neuropsychological investigations have been rarely performed in patients with juvenile myoclonic epilepsy (JME). We aimed to quantify the cognitive function in JME patients using various neuropsychological tests. Methods: We compared cognitive function in 27 JME patients with that in 27 healthy volunteers using tests examining cognitive performance, such as the verbal and visual memory, frontal function, attention, IQ score, and mood. In the JME group, we examined risk factors for cognitive function such as age, sex, family history, education level, age at seizure onset, seizure frequency, EEG abnormality, disease duration, and previous intake of antiepileptic drugs. Results: Verbal learning was significantly lower in JME patients than in controls, and attention and verbal fluency were impaired in JME patients compared with controls. However, general intellectual ability and mood did not differ between the groups. Early onset of seizure and long duration of disease were closely related to impaired cognitive function. Conclusions: JME patients may exhibit impaired cognitive function, in terms of memory and execution, despite having normal intelligence and mood.

Purpose: The aim of this study was to compare the difference in acute stroke management between urban and rural areas, to investigate the factors affecting these differences,and to acquire basic information for establishing an efficient regional hub and spoke system for stroke patients. Methods: This retrospective study was based on adult patients diagnosed with acute ischemic stroke from January 2012 to December 2012 at a regional cerebrovascular center. The term “acute” was defined as 24 hours from symptom recognized. The term “urban” was defined as the region within the boundary of a metropolitan area. The distance from the symptom onset location to the stroke center was calculated using a global positioning system. Results: The rate of arriving at a stroke center within 3hours after stroke recognition for acute ischemic stroke patients was much higher in urban areas compared to rural areas (27.5 vs. 19.2%, respectively; p-value=0.011). In stroke cases in rural areas, the distance from symptom onset location to a stroke center was determined as statistically significant through multivariate logistic regression analysis (Odds ratio (OR), 0.982; 95% Confidence interval (CI) 0.969-0.995). In contrast, the use of a public ambulance (OR, 4.258; 95% CI 2.233-8.118) and inter-hospital transfer (OR, 0.416; 95% CI 0.216-0.800) were the main prehospital delay factors in urban areas. Conclusion: For stroke cases in urban areas, it was important to directly visit a stroke center without transfer using a public ambulance. For rural areas, a new hub hospital and policies are necessary for reducing prehospital delay.

Spinal cord infarction is rare, especially cervical cord infarction is lesser than thoracic and lumbar level. We describe two cases of cervical cord infarction following cerebellar infarction with vertebral artery occlusion, which initially presented with chest pain and dyspnea. Blood supply for the cervical cord comes from anterior and posterior spinal artery, which originated from the distal vertebral or posterior inferior cerebellar arteries. Therefore, occlusion of unilateral vertebral artery could cause a cervical cord infarction.
스쿠버다이빙이 원인으로 추정되는 내경동맥박리로 인한 앞맥락동맥 영역 뇌경색

We report a case of anterior choroidal artery territory infarction due to internal carotid artery dissection presumably caused by scuba diving. A 44-year-old man presented with left facial palsy and hemiparesis. He had a history of scuba diving for 18 months. His last dive was 7 days ago, and he skipped decompression practice at that dive. We assumed that repetitive traumas and microbubbles during scuba diving, which made endothelium vulnerable to damage may have caused a carotid dissection.

Although randomized control trials about endovascular treatment (EVT) of emergent large vessel occlusion (LVO) have demonstrated the success of mechanical thrombectomy as the choice of treatment, a wide range of caveats remain unaddressed. Asian patients were rarely included in the trials, thereby raising the question of whether the treatment could be generalized. In addition, there remains a concern on the feasibility of the method with respect to its application against intracranial atherosclerosis (ICAS)-related LVO, frequently observed in the Asian population. It is important to include evidence on ICAS LVO from Asian countries in the future for a comprehensive understanding of LVO etiology. Besides the issues with EVT, prognostic concerns in diabetes patients, acute kidney injury following EVT, neuroprotective management against reperfusion injury, and other peri-EVT issues should be considered in clinical practice. In the current article, we present an in-depth review of the literature that revises information pertaining to such concerns.
