Background: Acute cerebral infarction is a major risk factor for postoperative neurologic complications in cardiac surgery. However, the outcomes associated with acute silent cerebral infarction (ASCI) have not been not well established. Few studies have reported the postoperative outcomes of these patients in light of preoperative Diffusion-weighted magnetic resonance imaging (DWI). We studied the postoperative neurologic outcomes of patients with preoperative ASCI detected by DWI. Methods: We retrospectively studied 32 patients with preoperative ASCI detected by DWI. None of the patients had preoperative neurologic symptoms. The mean age at operation was $68.8{\pm}9.5$ years. Five patients had previous histories of stroke. Four patients had been diagnosed with infective endocarditis. Single cerebral infarct lesions were detected in 16 patients, double lesions in 13, and multiple lesions (>5) in three. The median size of the infarct lesions was 4 mm (range, 2 to 25 mm). The operations of three of the 32 patients were delayed pending follow-up DWI studies. Results: There were two in-hospital mortalities. Neurologic complications also occurred in two patients. One patient developed extensive cerebral infarction unrelated to preoperative infarct lesions. One patient showed sustained delirium over one week but recovered completely without any neurologic deficits. In two patients, postoperative DWI confirmed that no significant changes had occurred in the lesions. Conclusion: Patients with preoperative ASCI showed excellent postoperative neurologic outcomes. Preoperative ASCI was not a risk factor for postoperative neurologic deterioration.

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.

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.

Objectives : This study investigated stroke lesions and their relationship with warning signs and risk factors in stroke patients. Methods : Three hundred fifty-three stroke patients were recruited at the Department of Cardiovascular and Neurologic Diseases (stroke center) of Kyung Hee University Oriental hospital from October 2005 to July 2007. We evaluated their stroke lesions with brain MRI, their warning signs, and risk factors. Results : 353 subjects were included in the final analysis. The frequency of diabetes was found more in presence of brain stem lesion than without. The cortex lesion showed a close relationship with smoking, drinking and the frequency of one side paralysis or weakness. These were more common in males than in females. Conclusions : We observed stroke lesions and their characteristics in stroke patients. The subjects' brain lesions seemed affectedby the risk factors. A concrete conclusion can hardly be drawn from this study; additional research is necessary.

Objectives : This study was performed to evaluate the relationships among blood-stasis. cardio-ankle vascular index(CAVI) and cardiovascular risk. Methods : We obtained general characteristics. blood-stasis score and CAVI from 150 stroke patients. Blood-stasis score was evaluated by blood-stasis criteria. Cardiovascular risk (the following. Stuart's risk score) was evaluated by Stuart's risk scoring scale. We divided subjects into a blood-stasis group and a non blood-stasis group by blood-stasis scores. high CAVI and normal CAVI groupsby CAVI. We compared the general characteristics. CAVI (excluded from comparison between high CAVI group and normal CAVI group), Stuart's risk score and blood-stasis score (excluded from comparison between blood-stasis group and non blood-stasis group) between each pair of groups. Pearson correlation analysis was applied to examine the relationship between blood stasis score and CAVI, blood stasis score and Stuart's risk score. CAVI and Stuart's risk score. Results : The blood-stasis group had significantly higher CAVI and Stuart's risk scores than the non blood stasis group. The high CAVI group had significantly higher blood-stasis score and Stuart's risk score than the normalCAVI group. In correlation analysis. there were significant positive relationship between blood stasis score and Stuart's risk score, CAVI and Stuart's risk score. and blood stasis score and CAVI. Conclusions : This study suggeststhat there is a significant relationship among blood stasis,CAVI and cardiovascular risk.

Objectives : This study was to assess the effectiveness of oriental medical therapy (OM) on acute Bell's palsy, comparing its outcome with that of oriental-western medical therapy (OWM). Methods : Subjects were enrolled atKyung Hee Medical Center from March 2007 to December 2007. We prescribed Igigeopung-san and acupuncture therapy to both the OM and OWM groups, and prednisolone only to the OWM group. Effectiveness was assessed by the House-Brackmann facial nerve grading system (HBGS) and Yanagihara's unweighted grading system (YUGS) every week. Results : There were 31 patients in the OM group and 34 in the OWM group. About grading system scores and weekly score gaps, no significant differences were revealed between the two groups, but statistical significant difference was detected at recovery time. After 2 weeks of treatment, the OM group's HBGS score showed significant difference from baseline score, but the OWM group showed it after 1 week. After 3 weeks of medication, pain was reduced in 22% of OM group patients, but 50% in the OWM group (p=0.028). We made the same comparison study for patients treated within 4 days from onset, but there was no significant difference between the two groups. 3 cases of adverse effect of hyperglycemia were found in the OWM group, which could be due to hyperglycemic side-effect of prednisolone. Conclusion : This work could help us to understand the effectiveness of OM compared to OWM on acute Bell's palsy.

Objective : The purpose of this study was to investigate the neuroprotective effect of Jukryuk on 4-vessel occlusion(4-VO) and middle cerebral artery (MCA) ischemia. Method : After administration of Jukryuk, we compared the Jukryuk-treated group, the control, and the sham groups, in view of several points as follows 1) We evaluated the damage characterized by coagulative cell change of pyramidal neurons and pronounced gliosis in each group 2) We counted the number of normal pyramidal shapes after ischemia in each group 3) Immunohistochemistry (cyclooxygenase-2) 4) In focal ischemic injury model, we measured the volume of ischemic area Results : In this experiment, the effect of Jukryuk was determined to be protecting neuron cell shape, reducing the number of neuron cells damaged by ischemia and the volume of the ischemic area. In immunohistochemistry, Jukryuk reduced cyclooxygenase-2 expression Conclusions : According to this study, Jukryuk can protect neuron cells from injury by cerebrovascular ischemia.

Objectives : This study was to assess the effectiveness of Oriental medical treatment on carpal tunnel syndrome, comparing its outcome with that of Western medical treatment. Methods : After being diagnosed with carpal tunnel syndrome by electromyography, subjects were enrolled in Kyung Hee Medical Center from March 2006 to January 2007. We prescribed Kejibokryung-hwan to the Oriental medical therapy group (OM group) and NSAIDS to the Western medical therapy group (WM group). Effectiveness was assessed by degree of pain using visual analog scale (VAS) before and after 3 weeks' treatment. Adverse effects were also monitored. Results : There were 21 patients in the OM group and 19 in the WM group. No statistical significant difference was detected at the baseline assessment. After 3 weeks of medication, pain was reduced about 26% in the OM group and 46% in the WM group. These findings might be explained by that more than half of the WM group received local steroid injection, which has been known to have more rapid analgesic effect that oral medication. Although pain reduction rate was higher in the WM group than in the OM group, we suggest that Oriental medical treatment is still effective, faking into consideration the fact that completely recovered cases were found only in the OM group. No adverse effect was found in either of the groups. Conclusion : This work could help us to understand the effectiveness of Oriental medical treatment on carpal tunnel syndrome.

Objectives and methods : The Euibujipsung is one of the huge-scale encyclopedias about Oriental Medicine. To search the most frequently used aupoints for dysarthria after stroke, we used Euibujipsung CD-ROM database with several chinese character keyword concerned with vernal function(語, 言, 音, 啞, 瘖, etc). Results : We found four popular acupoints(PC5, GV20, GV16, TE6), and five meridians (Governor vessel, Gall Bladder, Heart, Large Intestine and Triple Energizer). We also found that the extra meridians were used more frequently than other type of meridians. Conclusion : We think that these findings can give further ideas to clinical practice and research fields for stroke rehabilitation in Oriental medicine.
