BACKGROUND: Recent advances in stroke therapies require patients to be treated very early after the onset of symptoms. To reduce the delay in time upon stroke and arriving at the hospital, we assessed the time delay, stroke recognition, and awareness before and after a public education program designed to increase recognition and awareness. METHODS: Prospective standardized and structured interviews were performed in 155 patients with ischemic stroke who were admitted to the Severance hospital before and after the public education program. The educational program included local newspaper articles, distribution of pamphlets, and lectures to 119 emergency care teams. Time delay, variable factors, stroke recognition, and stroke awareness of patients were then assessed (75 pre-education and 80 post-education groups). RESULTS: 52% of the pre-education group and 52.5% of the post-education group arrived at the hospital within 24 hours. Those who arrived within 3 hours were only 21.3% and 15% respectively. A direct visit to the hospital and a cardioembolic infarction appeared to be associated with a shorter time delay. About half of the patients recognized their symptoms as a stroke before a diagnosis was made by a doctor. Most of them had known that a stroke should be treated urgently. However, the stroke recognition and awareness was not associated with an early arrival, which suggests that their knowledge was not solid. The efforts to inform the public using local newspaper articles and pamphlets geared towards the local residents for the limited time period was not effective in shortening arrival times. CONCLUSIONS: Many of the stroke patients did not arrive within the therapeutic time window. Our findings suggest that extensive and multi-directional campaigns should be performed to reduce the time delay. Our findings also suggest that educational aims should include the need for the rapid treatment of stroke and a therapeutic time window as well as stroke recognition.

The authors present the case of basilar artery bifurcation area aneurysm showing the growth of sac. A 46-year-old man was admitted for evaluation of fluctuating dysarthria. He had a history of lacunar infarction 3 years ago. The cerebral angiogram, taken at that time, showed a small aneurysm on basilar artery bifurcation area. Surgical intervention was not performed because of its small size. Brain MRI, taken for evaluation of dysarthria, showed large signal void at the basilar artery bifurcation area and following cerebral angiogram revealed the growth of previous aneurysm in its size. This observation suggests that careful follow-up examination should be performed for incidental small sized aneurysm.

We performed a percutaneous vertebroplasty at the compressed L2 vertebral body of a 73-year-old female using a left-sided unilateral extrapedicular approach. She complained severe radiating pain and a tingling sensation in her left leg two hours after the vertebroplasty. Spinal computed tomographic scan showed a large retroperitoneal hematoma, and a subsequent spinal angiography revealed a left L2 segmental artery injury. Bleeding was successfully controlled by endovascular embolization. Recently, extrapedicular approaches have been attempted, allowing for the avoidance of facet and pedicle injury with only a unilateral approach. With this approach, however, the needle punctures the vertebral body directly. Therefore, this procedure carries the potential risk of a spinal segmental artery.

We report a very rare case of a rapidly calcified chronic epidural hematoma (EDH) in a neonate. A 26-day-old female infant was referred to us from a regional hospital because of drowsy mentality and a seizure attack. She was delivered through caesarian section because normal spontaneous vaginal delivery was prolonged and failed. At birth, mild scalp swelling was found on the right frontal area. Scalp swelling was spontaneously resolved and she was discharged without any problems. On the 25th day after her birth, the baby presented with drowsiness and hypotonia following a generalized tonic-clonic seizure. Magnetic resonance imaging (MRI) and a computed tomography (CT) scan revealed a chronic EDH that had a thick layer of calcification. A small burr-hole trephination was performed and a single silastic drainage catheter was inserted. After the operation, a total of 12 ml of liquefied hematoma was drained, and the patient's mentality improved from drowsiness to alertness. The patient was asymptomatic when discharged.

Obesity is considered a mild inflammatory state, and the secretion of inflammation-related cytokines rises as adipose tissue expands. Inflammatory cytokines, including tumor necrosis factor-alpha (TNF-alpha), interlukin 6 (IL-6) and monocyte-chemoattractant protein 1 (MCP-1), are modulated by adipose tissue and known to play an important role in insulin resistance which is the common characteristics of obesity related disorders. In this study we analyzed the effects of Sasa borealis leaves extract on inflammatory cytokines and insulin resistance in diet induced obese C57/BL6J mice. The obese state was induced by a high fat diet for 20 weeks and then the mice were divided into two groups; obese control group (OBC, n = 7) and experimental group (OB-SBE, n = 7). The OBC group was fed a high fat diet and the OB-SBE group was fed a high fat diet containing 5% Sasa borealis leaves extract (SBE) for 12 weeks. We also used mice fed a standard diet as a normal control (NC, n = 7). The body weight and adipose tissue weight in the OB group were significantly higher than those in the NC group. The effects of the high fat diet were reduced by SBE treatments, and the body weight and adipose tissue deposition in the OB-SBE group were significantly decreased compared to the OBC group. The OBC group showed higher serum glucose and insulin levels which resulted in a significant increase of incremental area under the curve (IAUC) and HOMA-IR than the NC group. Also, serum leptin, TNF-alpha, and IL-6 levels were significantly higher in the OBC group than in the NC group. In contrast, the OB-SBE group showed a reversal in the metabolic defects, including a decrease in glucose, insulin, IAUC, HOMA-IR, TNF-alpha, IL-6 and leptin levels. These results suggest that BSE can suppress increased weight gain and/or fat deposition induced by a high fat diet and theses effects are accompanied by modulation of the inflammatory cytokines, TNF-alpha and IL-6 secretion resulting in improved insulin resistance.

Object : This study was conducted to evaluate the surgical results of the active treatment of unruptured intracranial aneurysms (UIAs) and to suggest treatment indications. METHODS: Operations were performed on 49 patients with 52 UIAs between 1999 and 2005. Medical records and radiologic studies of the patients with UIAs were retrospectively reviewed. The clinical outcomes were evaluated in each patient by the modified Glasgow Outcome Scale (m-GOS) one month after operation. RESULTS: UIAs had a high frequency of a middle cerebral artery (MCA) and an internal carotid artery (ICA) aneurysm. Forty-four UIAs (84.6%) ranged between 5 mm to 15 mm in diameter. Fortysix UIAs were treated by clipping, 2 by wrapping, and coil embolization was used in 3 UIAs. In one patient, which had only one UIA, one procedure and one operation was performed. There was no surgical mortality. In most patients, surgical complications or neurological deteriorations were not found. In three patients, minor neurological deficits of ptosis (2 patients) and spinal subdural hematoma (1 patient) were newly developed after operation. However the patients completely recovered within 3 months after operation. Finally, the surgical mortality and morbidity rate was 0%. CONCLUSION: If the UIAs are larger than 5 mm in diameter and located in a susceptible area for rupture, surgical treatment should be considered for the UIAs. If operation is performed by an expert neurosurgeon, surgical clipping is one of the best treatment modalities with or without endovascular treatment.

Primary leptomeningeal malignant melanoma is rare entity. We present a case of primary leptomeningeal malignant melanoma of 66-year-old male, who had suffered severe headache, confusion, and right hemiparesis. The brain computed tomography and magnetic resonance image revealed a well enhancing mass with hemorrhage in the left fronto-parietal region. Total surgical removal of the lesion was performed without neurological deficit. He died at home 6 months after operation. Probably, it seems that the cause of death was poor general condition due to obtunded mentality or brain herniation due to increased intracranial pressure. The literature on this subject is briefly reviewed.

Spinal subdural hematoma(SSDH) is rare disease. Furthermore, it rarely occurs as a complication of intracranial surgery. There are few case reports which describing SSDH after craniotomy. Although the exact pathogenetic mechanism is obscure, some investigators propose that downward migration of intracranial hematoma by the effect of gravity is one of the cause of SSDH, and which is commonly suggested. But others propose that cerebrospinal fluid(CSF) hypotension is an another possible mechanism. In this paper, we report two cases of SSDH after clipping of an aneurysmal neck.

OBJECTIVE: To determine the relationship between the clinical outcome and the extent of surgical laminectomy for adequate decompression on the cases of cauda equina syndrome, the authors review and analyze their cases and compared with those of literatures. METHODS: The authors reviewed 655 patients retrospectively who had underwent surgery on the cases of lumbar disc herniation from January 2000 to December 2004. There were 19 patients (2.9%) who presented for clinical cauda equina syndrome. Among them, we selected and analyzed 15 patients who were treated by unilateral partial hemilaminectomy with discectomy or bilateral partial laminectomy with discectomy, and they had been followed from 5 weeks to 47 months postoperatively (mean, 13.47 months). The levels of the disc herniations were L4-5 in 8 patients, following L5-S1 in 4 patients and 2 levels(L4-5 and L5-S1) in 3 patients. Motor and sensory recoveries were recorded. Postoperative urinary function recovery was defined according to Gleave and Macfarlane7). RESULTS: In 12 months postoperatively, the bladder function was obtained in 14 of 15 patients(93%) with regaining urinary continence. Thirteen of 15 patients(86%) with preoperative motor weakness of lower extremities were recovered. Sensory deficit of lower extremities, perianal and saddle anesthesia were all recovered. Patients had recovered on lumbosciatic pain and saddle hypesthesia, in turn, motor function and urinary incontinence. CONCLUSION: In treating cauda equina syndrome, the authors did less extensive surgery, such as unilateral partial hemilaminectomy with discectomy or bilateral partial laminectomy with discectomy for adequate decompression. The outcome is satisfactory and comparable with those of subtotal or total laminectomy.

Ankylosing spondylitis (AS) is a chronic inflammatory rheumatic disease. Pathologic changes occurred in patients with AS result in a weakened vertebral column with increased susceptibility to fractures, even though a trivial injury. Fractures usually tends to involve the lower cervical spine, but rarely, they are also occurred in thoracolumbar spine. We present our experiences of three cases of spinal fracture in patients with AS, cervical, thoracic, and lumbar spine, with a review of literatures.
