BACKGROUND: More than 90% of acute stroke patients have measurable cardiovascular sequelae, but we have been often overlooked in formal discussions of treatment. If we estimate the incidence of myocardial injury in patient with spontaneous SAH, we may figure the possibility of cardiac dysfunction in such patients. This study was designed to investigate the incidence of myocardial injury in patients with spontaneous SAH using cardiac troponin I(cTnI). METHODS: A prospective single emergency center study was performed to determined preoperative incidence of unrecognized cardiac injury in patients suffering spontaneous SAH. We include the spontaneous SAH patients who underwent serum measurements of the cardic troponin I immediately upon admission last six month period. ECG, CK, CK-MB and myoglobin were also performed at admission. We excluded the spontaneous SAH patients who had past history of myocardial ischemia and ECG abnormality. RESULTS: Fifty-two patients(34 females, 18 males) with spontaneous SAH were studied prospectively. 18 patients(34.6% of the total study population) had cTnI level above 0.5ng/ml. ECG was performed in 52 patients and was abnormal in 15 of the 52 patients(28.8%). CONCLUSION: The measurement of cTnI has provided physicians with a myocardial marker that has a cardiac sensitivity for cardiac injury equal to that of CK-MB yet with greater specificity. So, cardiac troponin I is useful to estimate the incidence of myocardial injury in patients with spontaneous SAH. And we may estimate the possibility of cardiac dysfunction in such patients. This knowledge will hopefully aid in the care and improve the outcome.

PURPOSE : To investigate the incidence and prevalence of C-shaped root canal using computed tomographic images of head and neck in Korean population. MATERIALS AND METHODS : Regardless of each examination purpose, randomly selected 268 examples which have serial axial computed tomographic images with 8 normal molars in maxilla and mandible were selected and investigated. Defined C-shaped root canal and we could get 82 proper image examples in view of this definition. These were detected and investigated of incidence and prevalence of C-shaped root canal. RESULTS : C-shaped root canals were found in 82 examples among 268 (30.6%) and 147 teeth. They were only found on molar area, and the highest incidence was 37.41% of left mandibular second molars, and the lowest was 2.04% of right maxillary second molars. On prevalence of tooth position, mandibular second molar was the highest, 65% of C-shaped root canal teeth and maxillary second molar was 6% the lowest. CONCLUSION : 31% of randomly selected CT images no considering check-up reason have C-shaped root canals. The C-shaped root canals of mandibular second molar are found most frequently and they are also detectable on maxilla. On Korean population, C-shaped root canals are one of conditions that have to concern with dental treatment for it appears at a high prevalence relatively.

PURPOSE: A pancreatic ductal adenocarcinoma is one of the most fatal cancers, as the majority of the patients present with locally advanced or metastatic tumors in the late stages of the disease. However, there is no simple, sensitive, noninvasive, and inexpensive test for the early detection of pancreatic ductal adenocarcinomas. In recent studies, S100A4 has emerged as an important protein in the tumorgenesis of pancreatic adenocarcinomas. METHODS: The possibility of the expression of S100A4 as a new tumor marker of pancreatic adenocarcinomas was confirmed using immunohistochemistry to 32-pancreatic ductal adenocarcinomas, 20 IPMN (intraductal papillary mucinous neoplasm), 8 serous cystadenomas, 5 chronic pancreatitis and 3 neuroendocrine tumors. RESULTS: Thirty-one (96.9%) ductal adenocarcinoma cases and 11 (55.5%) IPMN expressed S100A4, whereas all normal pancreatic tissues (47 cases), chronic pancreatitis and endocrine tumors did not. The expression of S100A4 was associated with the degree of dysplasia in IPMN, but not with the differentiation of ductal adenocarcinomas. CONCLUSION: The overexpression of S100A4 in adenocarcinomas and early emerging IPMN may suggest its potential as a diagnostic marker for the early detection of pancreatic ductal adenocarcinomas.

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.

OBJECTIVE: A variety of factors are known to have an influence on the recurrence of chronic subdural hematoma (CSDH). In this study, the authors investigated the influential factors for recurrence of CSDH after burr hole drainage. METHODS: 45 patients with unilateral CSDH were treated with one-burr hole trephination and closed drainage in our hospital during last 6 years, whom the drainage catheter tip was randomly located and checked on postoperative computed tomography (CT). The clinical status of patients, thickness of hematoma, midline displacement of before and after surgery, amount of subdural air collection, drainage catheter tip location were estimated and the relationship of those factors with the recurrence was analyzed. RESULTS: Patients with located catheter tip in frontal had a better clinical and radiological result. And the recurrence of CSDH was lower who has lesser amount of subdural air collection in postoperative CT. CONCLUSION: The recurrence rate of unilateral CSDH is influenced by the location of drainage catheter tip and the amount of subdural air collection.

Familial intracranial aneurysm is rare. We have clipped two posterior circulation intracranial aneurysms in mother and son. Mother was 48 years old and presented with severe headache and drowsy mentality. A basilar artery bifurcation aneurysm was found on DSA(digital subtraction angiography) and successfully clipped with transsylvian pterional approach. Her son was 24-year-old and presented with seizure and drowsy mentality. An aneurysmal sac was found on the bifurcation of vertebral artery and posterior inferior cerebellar artery. We have clipped it successfully with far lateral suboccipital approach. The authors recommended the use of screening test, such as MRIand high resolution CT, on the group of patients with the characteristic features of familial intracranial aneurysm.

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.

OBJECTIVES: We aimed to develop a common health information exchange (HIE) platform that can provide integrated services for implementing the HIE infrastructure in addition to guidelines for participating in an HIE network in South Korea. METHODS: By exploiting the Health Level 7 (HL7) Clinical Document Architecture (CDA) and Integrating the Healthcare Enterprise (IHE) Cross-enterprise Document Sharing-b (XDS.b) profile, we defined the architectural model, exchanging data items and their standardization, messaging standards, and privacy and security guidelines, for a secure, nationwide, interoperable HIE. We then developed a service-oriented common HIE platform to minimize the effort and difficulty of fulfilling the standard requirements for participating in the HIE network. The common platform supports open application program interfaces (APIs) for implementing a document registry, a document repository, a document consumer, and a master patient index. It could also be used for testing environments for the implementation of standard requirements. RESULTS: As the initial phase of implementing a nationwide HIE network in South Korea, we built a regional network for workers' compensation (WC) hospitals and their collaborating clinics to share referral and care record summaries to ensure the continuity of care for industrially injured workers, using the common HIE platform and verifying the feasibility of our technologies. CONCLUSIONS: We expect to expand the HIE network on a national scale with rapid support for implementing HL7 and IHE standards in South Korea.

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.
