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.

Arteriovenous mafformation(AVM) of female pelvic organ is a rare disease of unknown cause. The authors' report a case of pelvic AVM which was incidentally found during US examination of the patient with choriocarcinoma after chemotherapy. The real-time sonography revealed several cystic lesions around the uterus with adjacent dilated tortuous vessels. The color Doppler sonography depicted abundant blood flow mixed with red and blue colors within the cystic lesions and rapid turbulent systolic and diastolic flows. CT showed well-enhancing round vascular lesions with elongated vessels in the pelvis, and MRI depicted signal-void cystic lesions on both T1 and T2 weighted images with small portions of high intensity within the lesions on T2 weighted image. The angiography revealed pelvic AVM fed by tortuous uterine and vaginal arteries with a dilated draining vein

PURPOSE: Results of 181 percutaneous needle aspiration biopsies performed with an 18-gauge needle during a period of 3 years were analyzed to determine efficacy and safety of the procedure. MATERIALS AND METHODS: Biposies were performed in patients that could not be diagnosed by bronchoscopy or sputum cytology. The biopsy procedure with 18-gauge Crown needle was guided by fiuoroscopy. The biopsy specimen placed in 10% formalin solution were histologically confirmed. RESULTS: In 160 patients(89%), the positive diagnosis was made by percutaneous needle aspiration biopsy. There were 153 lung lesions(120 malignant and 33 benign lesions) and 7 mediastinal lesions. the diagnostic accuracy of malignant and benign disease was 91% and 80% respectively. Complications included pneumothorax(n=11) and hemothorax(n=l):six of them required treatment with chest tube and the remainder showed spontaneous resporption. CONCLUSION: PCNB with an 18-gauge needle provided a reliable, relatively safe diagnostic tool to establish the diagnosis of both malignant and benign chest lesions.

OBJECTIVES: This study aimed to examine the point prevalence of anxiety, depression and the associated risk factors in hospitalized patients with cancer. METHODS: A total of 114 patients with cancer who admitted to the Cancer Center in St. Mary's Hospital were enrolled for a day. The patients were asked to complete Hospital Anxiety and Depression Scale(HADS). Sociodemographic and cancer related clinical variables were also evaluated. RESULTS: The point prevalence of anxiety and depression was 10.5% and 34.2%, respectively, as assessed with HADS. Logistic regression models revealed that distant metastasis was significantly associated with anxiety in patients with cancer and previous chemotherapy and Low socioeconomic status were significantly associated with depression. CONCLUSIONS: Our results indicate that more than one third of patients with cancer suffer from either anxiety or depression. In addition, previous chemotherapy as well as low socioeconomic status and distant metastasis were associated risk factors of anxiety and depression, respectively. These findings suggest the need for screening and systematized psychosocial intervention for psychological distress in hospitalized patients with cancer.

STATEMENT OF PROBLEM: The cement-type abutment would be needed for the reduction of its body in order to correct the axis and to assure occlusal clearance. In the case of intraoral preparation, there is a potential risk that generated heat could be transmitted into the bone-implant interface, where it can cause deterioration of tissues around the implant and failed osseointegration. PURPOSE: The purpose of this study was to assess the difference of the heat transmitting effect on external and internal connection implant types under various conditions. MATERIAL AND METHOD: For evaluating the effects of alternating temperature, the thermocoupling wires were attached on 3 areas of the implant fixture surface corresponding to the cervical, middle, and apex. The abutments were removed 1mm in depth horizontally with diamond burs and were polished for 30 seconds at low speed with silicone points using pressure as applied in routine clinical practice. Obtained data were analyzed using Mann-Whitney rank-sum test and Wilcoxon / Kruskal-Wallis Tests. PESULT: Increased temperature on bone-implant interface was evident without air-water spray coolant both at high speed reduction and low speed polishing (p<.05). But, the difference between connection types was not shown. CONCLUSION: The reduction procedure of abutment without using proper coolant leads to serious damage of oral tissues around the implant irrespective of external and internal connection type.

Central serous chorioretinopathy is a disease which causes decreased visual acuity and functional disturbance. As the subretinal fluid is absorbed, the visual acuity is improved but patient's complaint such as metamorphosia is remained. To assess the recovery of visual functional disturbance in response to absorption of the fluid, the hue discrimination and contrast sensitivity were tested in central serous retinopathy patients (N=30) at the first visit, first visit after the absorption of subretinal fluid, and final visit. At the first visit, there were stastically significant differences in the mean square root of total error score, blue-yellow and red-green partial error score between normal control group and central serous retinopathy group and stastically significant differences in all spatial frequency between normal group and central serous retinopathy group. First visit after the absorption of subretinal fluid, and final visit, there were stastically significant differences in the mean square root of total error score, blue-yellow and red-green partial error score between normal control group and central serous retinopathy group and stastically significant differences in mid-high spatial frequency between normal group and central serous retinopathy group.
