The purposes of this study was to determine the effects of limited hyperextension at knee joint using Limited Motion Knee Brace on balance and walking in patients with hemiplegia. The subjects of this study were 20 post-stroke hemiplegic patients admitted. Subjects were randomly assigned to either experimental group (Limited Motion Knee Brace group) or control group (manual restriction group). Both groups received traditional physical therapy intervention. The effects of each therapeutic method were evaluated by measurements of gait ability assesment, Berg balance scale (BBS), 10-meter walk speed (10MWS), Timed Up & Go (TUG) Test. The results of this research were as followings: (1) After treatment, there were significant BBS scores differences in both experimental and control group compared with pre-treatment(p<0.05). (2) After treatment, there were significant TUG test scores differences in both experimental and control group compared with pre-treatment (p<0.05). (3) After treatment, there were significant 10MWS differences in both experimental and control group compared with pre-treatment (p<0.05). (4) There were significant BBS scores differences in third and fourth week between experimental and control group (p<0.05). It was concluded that Limited Motion Knee Brace was effective for improving balance and for reducing fatigue for experimental group. Therefore, further studies are required to investigate the effect of knee orthosis for improving balance and walking in patients with hemiplegia.

Background: At present, many surgeons prefer axillary artery cannulation because it facilitates antegrade cerebral perfusion and may diminish the risk of cerebral embolization. However, axillary artery cannulation has not been established as a routine procedure because there is controversy about its clinical advantage. Materials and Methods: We examined 111 patients diagnosed with acute type A aortic dissection between January 2000 and December 2009. The right axillary artery was cannulated in 58 patients (group A) and the femoral artery was cannulated in 53 (group F). The postoperative outcomes were retrospectively reviewed and compared between the two groups. Results: There were 46 male and 65 female patients with a mean age of $58.9{\pm}13.1$ years (range, 26 to 84 years). The extent of aortic replacement in both groups did not differ. There were 8 early deaths (7.2%) and 2 late deaths (1.8%). The mean follow-up duration was $46.0{\pm}32.6$ months (range, 1 month to 10 years). Transient neurologic dysfunction was observed in 11 patients (19.0%) in group A and 14 patients (26.4%) in group F. A total of 11 patients (9.9%) suffered from a permanent neurologic dysfunction. Early and delayed stroke were observed in 6 patients (10.3%) and 2 patients (3.4%), respectively, in group A as well as 2 patients (3.8%) and 1 patient (1.9%), respectively, in group F. There were no statistical differences in the cannulation-related complications between both groups (3 in group A vs. 0 in group F). Conclusion: There were no differences in postoperative neurologic outcomes and cannulation-related complications according to the cannulation sites. The cannulation site in an aortic dissection should be carefully chosen on a case-by-case basis. It is important to also pay attention to the possibility of intraoperative malperfusion syndrome occurring and the subsequent need to change the cannulation site.

The purpose of this study was to determined the effects of reciprocal inhibition on spatial-temporal gait parameters in spastic hemiplegic patients through GaitRite system. The subjects were consisted 45 patients who had spastic hemiplegia due to stroke. All subjects randomly assigned to 3 group : manual reciprocal inhibition program group(manual group), neuromuscular electrical stimulation group(NMES group) and control group. The manual group received voluntary isometric contraction of pre-tibia muscle. The NMES group received neuromuscular electrical stimulation on tibialis anterior. The control group was not recieved any therapeutic intervention. Before and after experiments, spatial-temporal gait parameters and functional ambulatory profile was measure in all patients. The data of 30 patients who complete experimental course were statistically analysed. The results of this study were as following : 1. The percentage of change of functional ambulatory profile were markedly increased in manual group but statistically non significant(p>.01). 2. The percentage of change of gait velocity and cadence were markedly increased in manual group but statistically non significant(p>.01). 3. Asymmetry ratio of gait elements were more improved in manual group but statistically non significant(p>.01). 4. There were no statistical difference between pre-test and post-test with functional ambulatory profile, gait velocity, cadence and asymmetry ratios in NMES group(p>.01). 5. There were no statistical difference between pre-test and post-test with unctional ambulatory profile, gait velocity, cadence and asymmetry ratios in control group(p>.01). In conclusion, the present results revealed that reciprocal inhibition which produced by voluntary isometric contraction of pre-tibia muscle can be improved spatial-temporal gait parameters including functional ambulatory profile in hemiplegic patients. Therefore, reciprocal inhibition is useful to improve functional activities in hemiplegic patient. Further study should be done to analyze the effects of intervention duration of reciprocal inhibition, appropriate muscle contraction, optimal time to apply the reciprocal inhibition in more long period.

Hyperlipidemia is one of the major factors causing the atherosclerosis of coronary arteries and well-documented modifiable risk factors of stroke, especially of the ischemic type. For Insulin-Dependent Diabetes Mellitus sufferers, if blood sugar is appropriately maintained, lipid and lipoprotein are normal, but if blood sugar is inappropriately maintained or clinical Diabetic nephropathy induces metabolic disorder of lipid, then Total cholesterol, low density lipoprotein cholesterol, triglyceride and very low density lipoprotein cholesterol levels go up and high density lipoprotein levels go down. The purpose of this study is to evaluate the effect of treatment with Ojeok-san and to observe the changes in Fasting Blood Sugar(FBS), 2 Hours Postprandial Blood Sugar(PP2h), Haemoglobin A1c(HbA1c), Total Cholesterol(T-Chol) and Triglyceride(TG). After the treatment, Fasting Blood Sugar decreased from 149mg/dl to 89mg/dl. 2 Hours Postprandial Blood Sugar decreased from l85mg/dl to 110mg/dl. Haemoglobin A1c decreased from 6.3% to 5.7%. Total Cholesterol decreased from 268mg/dl to 217mg/dl. And Triglyceride decreased from 438mg/dl to 265mg/dl. These results support a role for oriental medical therapy in treating Diabetic Hyperlipidemia. Further case studies of herbal treatment of this ailment are needed.

The urea cycle, consisting of a series of six enzymatic reactions, plays key roles to prevent the accumulation of toxic nitrogenous compound and synthesize arginine de novo. Five well characterized diseases have been described, resulting from an enzymatic defect in the biosynthesis of one of the normally expressed enzyme. This presentation will focus on two representative diseases; ornithine transcarbamylase(OTC) deficiency and citrullinemia(argininosuccinate synthetase deficiency). OTC deficiency is one of the most common inborn error of urea cycle, which is inherited in X-linked manner. We identified 17 different mutations in 20 unrelated Korean patients with OTC deficiency; L9X, R26P, R26X, T44I, R92X, G100R, R141Q, G195R, M205T, H214Y, D249G, R277W, F281S, 853 del C, R320X, V323M and 10 bp del at nt. 796-805. These mutations occur at well conserved nucleotide sequences across species or CpG hot spot. The L9X and R26X lead to the disruption of leader sequences, required for directing mitochondrial localization of the OTC precursor. Their phenotypes are severe, and neonatal onset. The G100R, R277W and V323M mutations were uniquely identified in patients with late onset OTC deficiency. The other genotypes are associated with neonatal onset. Out of 20 patients with OTC deficiency, only 6 patients are alive; two were liver transplanted, and normal in growth and development at 2, 4 years after transplantation respectively. Citrullinemia is an autosomal recessive disease, caused by the mutations in the argininosuccinate synthetase(ASS) gene. We identified in 3 major mutations in 11 unrelated Korean patients with citrullinemia; G324S, $IVS6^{-2}$ A to G, and 67 bp ins at nt 1125-1126. Among these, the 67 base pair insertion mutation is novel. The allele frequency of each mutation is; G324S(45%), IVS6-2 A to G(32%), and 67 base pair insertion(14%). All patients are diagnosed at neonatal or infantile age. Interestingly, two patients presented with stroke like episode. Out of 11 patients, 5 patients died. Among 6 patients alive, one patient was successfully liver transplanted.

To improve the oral health status of Korean people, it is necessary to encourage proper oral hygiene management habits, such as toothbrushing, through appropriate health promotion techniques. Therefore, the purpose of this study was to evaluate the removal of plaque and tooth abrasion using ultra-soft (filament 0.11~0.12 mm) and soft toothbrushes for toothbrushing. The plaque removal was performed using a dentiform and Arti-spray, and the Patient Hygiene Performance (PHP) index was calculated as the sum total score divided by the total number of surfaces. In the abrasivity experiment, according to the number of brushings, a micro Vickers hardness tester was used, and a sample in the range of 280~380 Vickers hardness number was selected. The number of toothbrushing stroke were 1,800 (2 months), 5,400 (6 months), 10,800 (12 months), and 21,600 (24 months). The tooth abrasion was measured using a scanning electron microscope. Statistical analysis was performed using IBM SPSS Statistics 22.0 and a p-value <0.05 was considered significant. According to the results, there was no statistically significant difference in the degree of plaque removal between ultra-soft and soft toothbrushes. The difference in tooth abrasion between before and after toothbrushing was found to be greater with the soft toothbrushes than with the ultra-soft toothbrushes. Therefore, the ultra-soft toothbrush not only lowers tooth damage by reducing tooth abrasion, but also shows a similar ability to remove plaque as soft toothbrushes.

Hypertension is an important public health problem because it increases the risk of stroke, angina, myocardial infarction, heart failure, and end-stage renal disease. If it is not actively treated, morbidity and mortality increase with hypertension-induced complications and quality of life decreases. This study was to evaluate the use of antihypertensive drugs and blood pressure changes and to compare algorithms chosen (or the 1st and 2nd line therapy of hypertension based on the JNC VI recommendations. The medical charts of 222 patients with essential hypertension at St. Vincent's Hospital in Suwon from January 1997 to January 2000 were reviewed retrospectively. Data collection and analysis included baseline BP underlying diseases and complications, administered antihypertensives, BP changes, changes of antihypertensive regimen, and adverse effects with treatments. As results, the higher BP the patients had, the more frequent they had target organ damages and clinical cardiovascular diseases. Mean duration to reduce blood pressure less than 140/90 mmHg was 8 weeks in $85.3\%$ of the patients. The rate of control in BP was $82.4\%$ at 6 months. The major antihypertensive drugs prescribed were calcium channel blockers $(61.8\%)$ , ACE inhibitors $(19.1\%),\;\beta-blockers\;(13.7\%)$ and diuretics $(5.3\%)$ as the 1st-line monotherapy. The methods of treatment used as the 1st-line therapy were monotherapy$(59\%)$ and combination therapy $(41\%)$. Blood pressure change was significantly greater for combination therapy than monotherapy$(-26.2\pm21.4\;vs.\;-18.56\pm16.7$ mmHg for systolic blood pressure; P<0.003, $-16.9\pm13.2\;vs.\;-9.2\pm12.8$ mmHg for diastolic blood pressure; p<0.001). When blood pressure was not completely controlled with the first antihypertensive selected, the 2nd line therapy had 4 options: addition of 2nd agent from different class; $66.2\%$, substitution with another drug, $21.9\%$ increase dose $11.9\%$ continue first regimen $27.9\%$ Calcium channel blockers were the most frequently prescribed agents. This was not comparable to the JNC VI guideline which recommended diuretics and $\beta-blockers$ for the 1st-line therapy. Most of patients achieved the goal BP and maintained it until 6 months, but the remaining patients should be controlled more tightly to improve their BP with combination of life style modification, patient education, and pharmacotherapy.

Background: We assessed the efficacy of intraoperative intra-aortic balloon pump therapy for achieving hemodynamic instability during off-pump coronary artery bypass surgery. Material and Method: We studied seven hundred ninety-six patients who underwent off-pump coronary artery bypass between January 2000 and December 2006. The patient were divided into group I (n=39), which received intraoperative intra-aortic balloon pump therapy, and group II (n=757), which did not receive intraoperative intra-aortic balloon pump therapy. Result: There were no differences in the operative mortalities (2.6%, 1/39 vs 0.8%, 6/757; p=0.195) and morbidities such as atrial fibrillation (p=0.691), stroke (p=0.908) and mediastinitis (p=0.781) between the 2 groups, although the ventilator support time, the length of the intensive care unit stay and the length of the hospital stay were longer in group I than in group II (p<0.05). Multivariate analysis failed to prove that group I was a high risk group for operative mortality (p=0.549). There were 3 intraoperative intra-aortic balloon pump-related complications in group I (7.9%). However, no longer complications occurred after 2003, when the surgeons began using a smaller sized 8 F catheter that was inserted using a sheathless technique. Conclusion: Intraoperative intra-aortic balloon pump therapy for achieving hemodynamic instability during off-pump coronary artery bypass surgery can be performed safely and it showed comparable clinical results to that of not using intraoperative intra-aortic balloon pump therapy.

Hemiplegic migraine (HM) is a rare subtype of migraine with aura and is accompanied by a fully reversible motor aura. HM can occur in two forms: familial or sporadic. Currently, three genes are related to familial HM. Typically, HM occurs in the first or second decade of life and involves gradually progressing aura symptoms in succession, accompanied by headaches. The aura includes visual, sensory, motor, aphasic and often basilar-type symptoms. Motor aura (weakness) is related to the regions where the sensory aura is involved, and it usually starts at the hand before spreading to the arm and face. Aphasia is a common form of speech aura, but does not typically present as a difficulty in understanding. In this case report, the sensory-motor aura started at the right face and then gradually progressed to the right leg without any symptoms in the ipsilateral upper extremity. To the best of my knowledge, there has been no previous case report for the presentation of a hemiplegic migraine, as in this case report. As there is a possibility of misdiagnosis of Bell's palsy at the early stage of this case, this case report suggests that a physician should consider the rare possibility of stroke or HM when a patient presents with unilateral facial palsy.

Objective : Emergency superficial temporal artery to middle cerebral artery (STA-MCA) anastomosis in patients with large vessel occlusion who fails mechanical thrombectomy or does not become an indication due to over the time window can be done as an alternative for blood flow restoration. The authors planned this study to quantitatively measure the degree of improvement in cerebral perfusion flow using perfusion magnetic resonance imaging (MRI) after bypass surgery and to find out what factors are related to the outcome of the bypass surgery. Methods : For a total of 107 patients who underwent emergent STA-MCA bypass surgery with large vessel occlusion, the National Institute of Health stroke scale (NIHSS), modified Rankin score (mRS), infarction volume, and hypoperfusion area volume was calculated, the duration between symptom onset and reperfusion time, occlusion site and infarction type were analyzed. After emergency STA-MCA bypass, hypoperfusion area volume at post-operative 7 days was calculated and analyzed compared with pre-operative hypoperfusion area volume. The factors affecting the improvement of mRS were analyzed. The clinical status of patients who underwent emergency bypass was investigated by mRS and NIHSS before and after surgery, and changes in infarct volume, extent, degree of collateral circulation, and hypoperfusion area volume were measured using MRI and digital subtraction angiography (DSA). Results : The preoperative infarction volume was median 10 mL and the hypoperfusion area volume was median 101 mL. NIHSS was a median of 8 points, and the last normal to operation time was a median of 60.7 hours. STA patency was fair in 97.1% of patients at 6 months follow-up DSA and recanalization of the occluded vessel was confirmed at 26.5% of patients. Infarction volume significantly influenced the improvement of mRS (p=0.010) but preoperative hypoperfusion volume was not significantly influenced (p=0.192), and the infarction type showed marginal significance (p=0.0508). Preoperative NIHSS, initial mRS, occlusion vessel type, and last normal to operation time did not influence the improvement of mRS (p=0.272, 0.941, 0.354, and 0.391). Conclusion : In a patient who had an acute cerebral infarction due to large vessel occlusion with large ischemic penumbra but was unable to perform mechanical thrombectomy, STA-MCA bypass could be performed. By using time-to-peak images of perfusion MRI, it is possible to quickly and easily confirm that the brain tissue at risk is preserved and that the ischemic penumbra is recovered to a normal blood flow state.
