Among these patients first 18 patients of PMV are the subjects of this study. 1) Among a total of 28 patients,10 patients were male and 18 patients were female patients. The age of the patients were between 21 and 59 years with the mean age of 40.9+/-12.2 Aortic Valve ; Atrial Fibrillation ; Balloon Valvuloplasty* ; Blood Pressure ; Cardiac Output ; Cardiac Tamponade ; Catheters ; Drainage ; Electrocardiography ; Embolism ; Female ; Humans ; Korea ; Male ; Middle Cerebral Artery ; Mitral Valve Insufficiency ; Mitral Valve Stenosis* ; Mitral Valve* ; Sepsis ; Thrombosis ; Vascular Resistance

BACKGROUND: We investigated the prevalence of dementia and mild cognitive impairment (MCI) and their risk factors in an urban community-dwelling elderly people over 65 years old. METHODS: A two-phase investigation was performed from January 2010 to December 2011. In Phase I, all subjects (n=9,485) responded to the Korean version of the Mini-Mental State Examination (K-MMSE). Based on the K-MMSE score the subjects were classified into two groups ('Normal' and 'Cognitive decline'). In Phase II, cognitive decline subjects were diagnosed as dementia or MCI according to the neuropsychological tests and doctor's interview. We also surveyed the socioeconomic and medical factors in Normal, Dementia and MCI groups. And we compared and analyzed the socioeconomic and medical risk factors by multiple logistic regressions in Dementia and MCI group. RESULTS: The prevalence of dementia and MCI was obtained 5.4% and 4.3%, respectively. Old age, alcohol intake, living together, low economic status, jobless in the past, diabetes mellitus, previous stroke, lower BMI and family history of dementia were associated with the increased dementia risk. Higher education, hypertension and physical activity were associated with the decreased dementia risk. And old age, alcohol intake, higher education, previous stroke, lower BMI and physical activity were common risk factors in MCI group. CONCLUSIONS: The prevalence of dementia and MCI was obtained much lower than previous reports. Dementia and MCI patients had common socioeconomic and medical risk factors. It is also important to control the risk factors earlier to prevent the increase of patients in dementia. And in order to prove the hypothesis that early control of the risk factors can decrease the occurrence of dementia, the further prospective studies are needed.

Non-ketotic hyperglycemia (NKH) is recognized both as a direct cause of a precipitating factor of many types of epileptic seizure, including simple partial motor, complex partial as well as reflex motor seizure, choreoathetosis and ballismus. Its association with isolated visual alteration is less known. A 74-year-old diabetic woman with visual complaints manifested as flashing colorful lights (red, yellow and blue) in both visual field with progressive increase in frequency. Among the laboratory tests, NKH of 508mg/dL stood out. Slow waves from the right occipital region maximum at O2 associated with visual symptom were recorded in EEG. Brain MRI showed subcortical T2WI and FLAIR hypointensities in the right occipital lobe with scanty enhancement. Patient was treated with hydration and insulin and her symptoms disappeared after hyperglycemia was corrected. We stress that isolated visual episodes may be initial manifestation of occipital lobe simple partial seizure associated with NKH.

10~25% of all cases of lymphoma involves the nervous system. Neurolymphomatosis, one of the complications of lymphoma, is rare clinical disorder with signs of peripheral neuropathy. It is also a rare cause of painful neuropathy and usually presents with sensorimotor polyneuropathy in nerve conduction studies. We report a case of neurolymphomatosis that had originated from a nasal type NK/T cell lymphoma with clinical and electrophysiological evidences of peripheral neuropathy, confirmed by histopathologic evidences of lymphomatous infiltration.

Toe deformities occurring after tibial shaft fracture can result from compartment syndrome or adhesion of muscle to tendon. Claw toes or checkrein deformity caused by injury of posterior compartment muscles has been reported relatively often. But, a deformity due to injury of the anterior compartment muscles is very rare. We observed the two cases of an extension deformity at the metatarsophalangeal joint of the hallux following intramedullary nailing of a tibial shaft fracture. There was no evidence of compartment syndrome. Extension deformity of the hallux was decreased with dorsiflexion of the ankle and increased with plantar flexion. Contracture of the extensor hallucis longus tendon was diagnosed, and Z-lengthening of that tendon was performed. Satisfactory results were obtained without a recurrence of deformity. We report these rare cases of toe deformities occurring after a tibial shaft fracture, with a brief review of the literature.

BACKGROUND AND PURPOSE: PurposezzInterest in gender differences in the effects of acute stroke is growing worldwide. However, gender differences in functional recovery after acute stroke in the Korean population have yet to be evaluated. The aim of this investigation was to compare long-term functional outcomes between male and female after acute stroke. METHODS: Patients with acute stroke were enrolled prospectively between January 2005 and January 2009. Baseline characteristics, risk factors, stroke subtypes, time delay from onset to arrival at a hospital, active treatment, and stroke severity were compared between male and female. Differences in mortality and disability at discharge, and at 3 months and 1 year after stroke onset were also investigated. Functional disabilities were categorized into two groups: good outcome (score on modified Rankin scale < or =2) and poor outcome (score on modified Rankin scale >2). RESULTS: Among 1,055 patients with acute stroke, 575 were male (aged 64.83+/-11.98 years, mean+/-SD) and 480 were female (aged 70.09+/-13.02 years). There were no gender differences in mortality at 3 months and 1 year after stroke. The frequency of poor outcomes was higher in female patients than in male patients at discharge (39.8% versus 30.9%, respectively; p=0.003), the 3 months follow-up (32.3% versus 20.8%, respectively; p<0.001), and the 1 year follow-up (31.1% versus 18.7%, respectively; p=0.001). After adjusting for multiple confounding factors including age and stroke severity, the female gender persisted as a predictor of poor functional outcome at 3 months and 1 year after stroke. CONCLUSIONS: Female patients have greater difficulty than male patients in recovering from a disabled state after acute stroke. Future studies should investigate the causes of this gender difference.

BACKGROUND AND PURPOSE: There is no clear description about the patterns of each mechanism of striatocapsular infarctions. The aims of our study were to elucidate differences in the distributions of lesions of acute middle cerebral artery (MCA) infarctions involving the striatocapsular region and to compare those following embolic striatocapsular infarctions with those originating from MCA disease. METHODS: We prospectively enrolled patients with acute infarcts located in the lenticulostriate artery territory that were not lacunar infarcts. Brain coronal diffusion-weighted imaging (DWI) was obtained and magnetic resonance angiography (MRA) was carried out to evaluate the distribution of infarct lesions and MCA stenosis in all patients. The types of infarct distribution were divided into three categories: (1) dominant in the distal territory (DD), (2) distributed equally between the distal and proximal territories (DE), and (3) dominant in the proximal territory. We performed tests for embolic sources (transthoracic echocardiography, transesophageal echocardiography, Holter monitoring, and contrast-enhanced MRA including the aortic arch) in most patients. Stroke mechanisms were classified into stroke from proximal embolism, MCA disease, and stroke of undetermined etiology. RESULTS: A total of 47 patients (28 men and 19 women; mean age, 62 years) were recruited. A proximal embolic source was significantly more prevalent in patients with a DE lesion than in those with a DD lesion. The most common proximal embolic source was of cardiac origin. In contrast, symptomatic MCA stenoses were more common in patients with a DD lesion than in those with a DE lesion. CONCLUSIONS: These results suggest that the dominant area of striatocapsular infarction on coronal DWI is an important clue for stroke etiology. Coronal DWI could therefore be helpful to determining the mechanisms in patients with striatocapsular infarctions that are currently described as having an "undetermined etiology" according to the Trial of Org 10172 in Acute Stroke Treatment classification.

PURPOSE: The reverse digital island flap is useful for the repair of various fingertip injuries. We present a modified surgical technique with skin strip elevation for the prevention of postoperative congestion. METHODS: From January 2005 to October 2015, we performed 31 reconstructive procedures for finger injury using a reverse digital artery island flap with and without skin strip retention. Patients' clinical characteristics, surgical outcomes, and complications were investigated. RESULTS: All flaps survived and there were no donor site problems. The mean follow-up time was 5 months (range, 3-8 months). In skin strip retention group, mild venous congestion was observed in 1 case, although it resolved spontaneously. Another case retained flexion contracture, and 2 patients had stiffness at the distal interphalangeal joint. Whereas, in no retention group, venous congestion was observed in 3 cases, 1 patient had partial flap necrosis and 2 patient suffer in flexion contracture at metacarpophalangeal joint. CONCLUSION: The reverse digital island flap procedure produces consistent results and is reliable for the treatment of fingertip injury. Our modified surgical technique of elevating the flap accompanied by skin strip retention helps prevent postoperative congestion.
