With 2mm-thick CT scanning during the rapid infusion of contrast material(TICT), cerebral aneurysms arising from the circle of Willis and adjacent vessels can be directly visualized. Twenty-five patients who had cerebral aneurysm confirmed by surgery were examined with TIGT and digital subtraction angiography. The authors examined TIGT prospectively to assess the detection rate of the cerebal aneurysms and to evaluate the clinical usefulness of TIGT. The detection rates of aneurysms by TIGT and digital subtraction angiography were 68% and 84%, respectively. TIGT is a rapid, safe and reliable method in the evaluation of patients with suspected cerebral aneurysm, permitting direct visualization of the aneurysm.

Open carpal tunnel release has been the standard method of sumical treatment of carpal tunnel syndrome. Recently endoscopic carpal tunnel release has been introduced and is heing used by many authors. The advantages of this new technique are less postoperative pain, rapid restoration of power and rapid return-to-work. However many considerate authors, in spite of these advantages. insist that the inevitahle risk of neurovascular injury during the endoscopic procedure should not he underestimated. The purpose of our study is to compare the clinical results of endoscopic carpal tunnel release with those of open release. 20 open carpal tunnel releases in 16 patients and 15 endoscopic carpal tunnel reieases (single-portal technique) in 11 patients were performed hy the first author. Preoperative conditions of both groups are not different. Authors compared the clinical results between the two groups with some parameters. The overall clinical results were not different significantly hetween two groups. Rapid return-to-work(36 days in endoscopic group versus 60 days in open group) and less postoperative scar and pillar pain in endoscopic group were demonstrated. However, the major complication of one median nerve injury in endoscopic group seemed to overweigh these some benefits. We suggest that the standard operative technique for carpal tunnel syndrome should be open carpal tunnel release and more considerations should be takcn in choosing endoscopic method because of its inherent risk.

Purpose: To evaluate the efficacy of the preventive abduction brace in dementia patients after bipolar hemiarthroplasty of the hip. Materials and Method: A review of 30 patients who had dementia prior to bipolar hemiarthroplasty of the hip. 20 females and 10 males were evaluated and their mean age was 80.4 years old (range, 68 to -92 years old). The average MMSE-K in dementia patients was 14.2 (range, 8 to 20). The reasons for the bipolar hemiarthroplasties were femoral neck fractures in all the cases. We analyzed the dislocation rates of those who had preventive abduction braces applied prospectively. Results: The average follow-up period after hemiarthroplasty was 2.2 years. All 30 patients had preventive abduction braces and no dislocations occurred after the bipolar hemiarthroplasties. Conclusion: Hip dislocations were not detected in those patients who preventive abduction braces applied. The present findings suggest that having a preventive abduction brace will definitely reduce the dislocation rate in dementia patients who have difficulties with rehabilitation after their operations.

PURPOSE: Congenital Iobar agenesis of the liver is a rare anomaly. We report five cases (three cases of right Iobar agenesis and two cases of left Iobar agenesis) and discuss the radiologic findings of this congenital anomaly. MATERIALS AND METHODS: Between July, 1992 and February, 1993, three cases of right Iobar agenesis and two cases of left Iobar agenesis of the liver were diagnosed by means of computed tomography(CT) and/or sonography. MR imging was performed in two patients, cholangiography in two, and digital subtraction angiography in one. RESULTS: The main findings of right Iobar agenesis of the liver were nonvisualization of the right portal vein and absence of liver tissue to the right of gallbladder. The findings of left Iobar agenesis were nonvisualization of left portal vein, absence of liver tissue to the left of the gallbladder, and absence of ligamentum teres. The ancillary finding of the Iobar agenesis was visualization of less than three hepatic veins. CONCLUSION: It is important to consider Iobar agenesis of the liver in differential diagnosis when imaging studies reveal abnormal portal vein branches, unusual position of gallblader, absence of ligamentum teres, and visualization of less than three hepatic veins.

A 81-year-old man was referred for respiratory failure by emergency medical technicians. He admitted at intensive care unit for ventilator treatment. Several hours before admission, he took sildenafil 100 mg for erectile dysfunction without prescription. The episodes of hemoptysis occurred several hours later. Computed tomography revealed multifocal diffuse ground-glass attenuation in both lungs. And the more we performed bronchoalveolar lavage, the more the color of it was turned into red. We treated him with empirical antibiotics and tranexamic acid, and hemoptysis was stopped in one day after admission. But in the 5th admission day, he died from sepsis combined with pneumonia caused by Acinetobacter baumannii abruptly.

We have experienced 4 cases which were clinically diagncsed as granuloma pyogenicum, but histologically as a malignant melanorna, an eccrine angiomatous hamartoma with granuloma pyogenicum, a subungual exostosis, and a lipoma, with granulation tissue. A granuloma pyogenicum may have clinical resemblances to various benign or malignant lesions. Therefore, any lesion that resembles a granuloma pyogenicum should have this clinical impression confirmed by histologic examination.

Carcinosarcoma, often referred to as "malignant mixed tumor" is a rare neoplasm, but this tumor occurs in various organs, including the gallbladder. We report herein a carcinosarcoma of the gallbladder which consisted of adenocarcinomatous and undifferentiated sarcomatous ares, the latter differentiating towards abundant osteoid and calcified but nonlamellated bony trabeculae formation. There are 18 reported cases of this type tumor of the gallbladder in the literature.

The relationship between the intestinal histopathology and number and position of intraepithelial lymphocytes (IEL) was observed chronologically in the small intestine of rats experimentally infected with Metagonimus yokogawai. Fifteen Sprague-Dawley rats were orally infected each with 3,000 metacecariae, and 3 were kept uninfected for controls. Three rats each were sacrificed on the day 5, 10, 15, 24 and 70 post-infection (PI) and samples of the small intestine, 5 cm, 10 cm, 20 cm and 70 cm posterior to the pylorus were taken. The samples were processed routinely and stained with Giemsa. The intestinal histopathology was severe during the day 5-15 PI and characterized by villous atrophy, crypt hyperplasia, and decrease of villus/crypt height ratio. After the day 24 PI, the intestinal lesions showed some tendency of recovery. The number of IEL increased at the early stage of infection, but decreased thereafter to a lower level than that of controls, with progression of the pathological changes. Then, the IEL number began to increase again after the day 24 PI. In control rats, the great majority of the IEL were located at the basal region of the epithelium. During the early stage of infection, however, a considerable proportion of IEL was found to have moved to the intermediate or apical region of the epithelium. From the above results, it is suggested that the change of IEL number and position during the course of M. yokogawai infection should be closely related to the progression and recovery of the intestinal histopathology.

BACKGROUND: This study aimed to empirically investigate the determinants on oxygen free radical degree which causes biological damage focusing on smoking habit and health behaviors in daily life. METHODS: In this cross-sectional study, the subjects were adult males who submitted free radical tests among the examinees of the comprehensive medical testings at an university hospital in Suwon from 2008 to 2010. Total 497 samples were used in analyses for clarifying the relations of free radical degree to age, smoking, obesity, and other health behaviors. RESULTS: First, the degree of oxygen free radical increases by 0.164 as the age group increases (P<0.05). Second, the degree of oxygen free radical increases by 0.547 as the smoking habit increases (P<0.001). Third, the degree of oxygen free radical increases by 0.087 as the exposure to hazardous factors in workplace increases (P<0.001). CONCLUSIONS: The findings of the study imply that the smoking habit has more great influence on the increase of oxygen free radical in body than any other health behaviors. The causality of free radical to smoking and health behavior was not identified due to the limit of the cross-sectional study so it needs to be studied prospectively in the future.
