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.

Trichloroethylene is a very common chemical used principally as a solvent and a degreasing agent in industry, We have experienced a case of toxic erythema, toxic hepatitis, and subsequent exfoliative dermatitis possibly due to trichloroethylene in a 23-year-old male. He had dealed with a cleaning process with trichloroethylene in a factory of stainless steel materials. We report our case with the review of the toxicity of trichoroethylene.

Studies on the correlation between proliferative activity of biopsied specimen and pathologic findings of resected specimen have been carried out to find the prognostic factors. To estimate the proliferative activity, 100 cases of biopsied specimen of gastric adenocarcinoma were tested for the PCNA (proliferating cell nuclear antigen) and the AgNOR (argyrophilic nucleolar organizer region) by the immunohistochemical and histochemical stainings, respectively. The resected tumors classified by histologic type, differentiation, depth of invasion, and nodal metastatic status were followed by cell cycle analysis using flow cytometry. The PCNA LI (labelling index) were higher in well or moderately differentiated tumors (P<0.01) than the poorly differentiated ones and the aneuploid tumors (P<0.05) more than in diploid ones. However, there were no correlations among histologic types, depth of invasion, nodal metastatic status and PCNA LI. The AgNOR counts were higher in advanced tumor than in the EGC (early gastric cancer) (P<0.01). In cases with nodal metastasis, most of them showed the AgNOR counts higher than those without nodal metastasis. There were no correlations between the AgNOR counts and the DNA ploidy, histologic type, or differentiation. High PCNA LI and high AgNOR counts were shown in cases with advanced tumors (P=0.000) and nodal metastasis (P<0.05). No correlation was shown with the histologic type or differentiation. The results show that proliferative activity of the biopsied specimen of gastric adenocarcinoma is correlated with the differentiation and the invasion depth of resected specimen. Especially, better correlation is obtained by analyzing both the PCNA LI and the AgNOR counts than by analyzing each.

The components of bore marrow change dramatically during lifetime. To evaluate the bone marrow of cranium and upper cervical spine, the authors retrospectively evaluated 300 examinations of cranium and the second cervical bone in patients without known bone marrow abnormality. T1-weighted images were used to analyze the changes of lone marrow signal intensity according to the age and sex. The signal intensity of bone marrow of cranium increased most rapidly from birth to age of 10 years. Between 11 and 20 years of age, gradual increase of signal intensity was noted. There was minimal augment of signal intensity after age of 20 years. The examination of signal intensity of bone marrow of the cranium revealed slightly higher score in male than in female. The synchondrosis of the second cervical vertebra was visible in 97%. These results may be useful in the detection of abnormal bone marrow signal of cranium and upper cervical spine.
