Journal of Vietnamese Medicine 2001;263(9):1-4
36 patients with age of 15-63 found the cerobrovascular pathology during 2/1997-2/1998 in friendship hospital by the cerebrovascular angiography. Methods: analysis of cerebral parenchyma to find the empty focus of sign and abnormal focus, taking the vascular photograph and analysis of the cerebrovasular by resetting as MIP program comparing with the images of CT scanner, image of DSA technique (4 patients) and results of operation (6 patients). The results have shown that the comparison of the operation (6 patients) with the angiography as technique DSA found that the MRI were suitable with the arteries with diameter of 5 mm and the abnormality of the vascular. The MRI of the cerebral parenchyma give the images which was more obviously than these of CT. scanner

2.Outcomes of the support services for the establishment of regional level 1 trauma centers.
Journal of the Korean Medical Association 2016;59(12):923-930
In Korea, injury is the third most common cause of death after cancer and cerebrovascular disease, but it is the major cause of death for the working age population under 40 years old. Also, the preventable trauma death rate in Korea is still higher than in developed countries. This fact has raised awareness of the need to establish a trauma system. For this reason, support services for the establishment of regional level 1 trauma centers was launched in 2012 by the Ministry of Health and Welfare. The purpose of this service is to designate 17 regional level 1 trauma centers distributed evenly across the country and to provide adequate care for seriously injured patients 24 hours a day, 7 days a week. As a result, the preventable trauma death rate is expected to fall to the level of the developed countries by 2020. As of November 2016, 16 regional level 1 trauma centers have been selected and 9 of them have officially opened. If the project is completed as planned, the quality of all phases of trauma care (prehospital, transport, and hospital) will be high, and the lives of seriously injured patients can more often be saved and their disabilities minimized.

PURPOSE: Altered mental status (AMS) is a collective phrase that describes an undifferentiated assortment of disorders of mentation including impaired cognition, attention, awareness, and level of consciousness. Although AMS is a common chief complaint and a frequent issue in the emergency department (ED), the clinical surveys of AMS have not been conducted in Korea. We analyzed the AMS patients on the clinical basis. METHODS: From march 2002 to may 2002, we had enrolled prospectively 256 adult patients who visited the ED of Sanggye Paik Hospital because of AMS. The patients accompanied by AMS clinically were included, excluding patients caused by trauma, cerebrovascular accident with alert mentality. The clinical records were reviewed to analyze the clinical features of AMS, 9 months after discharge from ED. RESULTS: AMS was found in 256 patients which comprised the 2.2% of the ED patients during the test period, and 112 patients were admitted. The most commonly encountered mental status was drowsiness(36.3%), and the overall mortality rate 10.2%. The AMS was caused by neurogenic, metabolic, alcohol-related, psychogenic disorders in frequency accounting for most of AMS etiologies. CONCLUSION: This survey shows that the incidence of AMS is 2.2%, old age increases the rate of admission, and the common etiologies are neurogenic, metabolic, alcohol-related disorders. It seems prudent to approach the patients with AMS on the basis of etiologies and age.

We review current topics in sport-related head injuries including acute subdural hematoma (ASDH), traumatic cerebrovascular disease, cerebral concussion, and chronic traumatic encephalopathy (CTE). Sports-related ASDH is a leading cause of death and severe morbidity in popular contact sports like American football and Japanese judo. Rotational acceleration can cause either cerebral concussion or ASDH due to rupture of a parasagittal bridging vein. Although rare, approximately 80% of patients with cerebral infarction due to sport participation are diagnosed with ischemia or infarction due to arterial dissection. Computed tomography angiography, magnetic resonance angiography, and ultrasound are useful for diagnosing arterial dissection; ultrasound is particularly useful for detecting dissection of the common and internal carotid arteries. Repeated sports head injuries increase the risks of future concussion, cerebral swelling, ASDH, and CTE. To avoid fatal consequences of CTE, it is essential to understand the criteria for safe post-concussion sports participation. Once diagnosed with a concussion, an athlete should not be allowed to return to play on the same day and should not resume sports before the concussion symptoms have completely resolved. Information about the risks and management of head injuries in different sports should be widely disseminated in educational institutions and by sport organization public relations campaigns.

OBJECTIVE: Blood blister-like aneurysms (BBAs) resemble arterial dissections. The purpose of this study was to investigate the relationship between these two disease entities and highlight commonalities and distinct features. METHODS: Among 871 consecutive patients with aneurysmal subarachnoid hemorrhage, 11 BBAs of internal carotid artery and seven vertebral artery dissections (VADs) with a short segmental eccentric dilatation (Mizutani type 4), which is morphologically similar to a BBA, were selected. The following clinical factors were studied in each group : age, gender, risk factors, Hunt and Hess grade (HHG), Fisher grade (FG), vasospasms, hydrocephalus, perioperative rebleeding rate, and treatment outcome. RESULTS: The mean age was 47.9 years in the BBAs group and 46.4 years in the type 4 VADs group. All the BBA patients were female, whereas there was a slight male predominance in the type 4 VAD group (male : female ratio of 4 : 3). In the BBA and type 4 VAD groups that underwent less aggressive treatment to save the parent artery, 29% (n=2/7) and 66.6% (n=2/3), respectively, eventually required retreatment. Perioperative rebleeding occurred in 72.7% (n=8) and 28.6% (n=2) of patients in the BBA and type 4 VAD groups, respectively. There was no statistical difference in the other clinical factors in both groups, except for the male dominancy in the type 4 VAD group (p=0.011). CONCLUSION: BBAs and ruptured type 4 VADs have a similar morphological appearance but there is a distinct clinical feature in gender and perioperative rebleeding rates. Complete isolation of an aneurysm from the parent artery might be the most important discipline for the treatment of these diseases.

OBJECTIVES: Although there have been several reports that described characteristics for young age stroke, information regarding very young age (18–30 years old) has been limited. We aimed to analyze demographic factors, stroke subtype, and 3-month outcome in acute ischemic stroke patient who have relatively very young age in multicenter stroke registry. METHODS: We evaluated all 122 (7.1%) consecutive acute ischemic stroke (within 7 days after symptom onset) patients aged 18 to 30 from 17,144 patients who registered in multicenter prospective stroke registry, 1997 to 2012. Etiology was classified by Trial of Org 10172 in Acute Stroke Treatment criteria. Stroke severity was defined as National Institutes of Health Stroke Scale (NIHSS) and stroke outcome was defined by modified Rankin scale (mRS) at 3 months after index stroke. RESULTS: The mean age of all included patients was 25.1±3.7 years and 76 patients (62.2%) were male. The median NIHSS at admission was 4. Considering stroke subtype, 37 patients (30.3%) had stroke of other determined etiology (SOD), 37 (30.3%) had undetermined negative evaluation (UN) and 31 (25.4%) had cardioembolism (CE) were frequently noted. After adjusting age, sex and variables which had P<0.1 in univariable analysis (NIHSS and stroke subtype), CE stroke subtype (odds ratio, 4.68; 95% confidence interval, 1.42–15.48; P=0.011) were significantly associated with poor functional outcome (mRS≥3). CONCLUSION: In very young age ischemic stroke patients, SOD and UN stroke subtype were most common and CE stroke subtype was independently associated with poor discharge outcome.

9.Clinical analysis of 34 diffuse axonal injured (DAI) patients below GCS 8.
Yonsei Medical Journal 1992;33(4):326-336
A consecutive series of 34 severe head-injured patients (DAI) were studied prospectively. Patients were categorized according to a new, simple classification system comprised of four lesion types according to the compression or obliteration of the ventricles or cisterns. Five patients belonged to type II and 19 patients to type IV. Each type was further subdivided into two GCS score ranges (5 to 8 and below 5). The distribution of the posttraumatic infarction was mainly in the frontal and temporal lobes (60% of all cases). Our data demonstrated that the ICP was significantly lower at a 30 degrees head elevation than at 0 degree (18.6 +/- 7.21 mmHg vs 23.0 +/- 10.60 mmHg. t = 4.22 p< 0.001), but head position did not statistically affect CPP (69.4 +/- 19.86 mmHg vs 68.2 +/- 19.87 mmHg. t = -0.54, p< 0.59). The effect of intensive therapy on ICP, CPP and AVDO2 was studied in all cases, employing steroids and diuretics in a modified intensive care scale. In cases where barbiturates were employed, there were statistically significant changes in ICP and AVDO2 (p< 0.001), but CPP was not affected (p< 0.59). Surviving patients were analyzed by using the GOS and the neurological grading score (NGS, Nihon University) of the persistent vegetative state. Our data suggests that head elevation of 30 degrees and barbiturate therapy are more effective on ICP and AVDO2, and NGS more exact than GOS in vegetative patients.
