Immunoperoxidase method was used to study carcinoembryonic antigen in tissue sections of 75 patients with transitional cell carcinoma, inflammation and normal mucosa of the bladder. Transitional cell carcinomas were divided into 3 grades by the degree of cellular differentiation and 4 groups (A: superficial tumors without recurrence, B: superficial tumors with recurrence, C: superficial tumors with recurrence and up-staging and D: initially invasive tumors) according to recurrence and invasiveness. Overall positive rate of CEA for transitional cell carcinomas was 38% and 5 normal and 5 inflammatory vesical mucosas were negative for CEA in the cytoplasm of the cell. The positive rates of A, B, C and D were 25%, 57%, 30% and 50%, respectively and those of grade I, II and III were l9%, 34 % and 73%, respectively. The positive rate of CEA was well correlated with the grade but not with the recurrence or invasiveness. These conflicting data suggest that further extensive study will be necessary whether immunoperoxidase detection of CEA in tissue sections could be of prognostic value in patients with transitional cell carcinoma of the bladder.

Purpose: To validate the value of Duplex Color Doppler Ultrasonography (DDU) for the incidence and location of postoperative deep vein thrombosis (DVT) that developed after hip surgery Materials and Methods: 260 consecutive patients who did not undergo any preventive treatment for DVT and underwent hip surgery (osteosynthesis for femoral neck and intertrochanteric fracture, acetabular fracture, and hip joint arthroplasty) from July, 2003 to May, 2005 were evaluated for the incidence of DVT. DDU was carried out on 7th postoperative day in all cases. Results: DVT was detected in 16 cases (6.2%) with 7 being in the femoral vein and 3 in the calf vein. Only two cases showed clinical symptoms such as pain and edema but no pulmonary embolism developed. Conclusion: The incidence of DVT obtained from DDU after hip surgery was 6.2 %, and no serious complications developed due to the early diagnosis. DDU is valuable as a screening test for postoperative DVT as well as for the prevention of serious complications such as pulmonary embolism.

PURPOSE: To determine the usefulness of microbubble contrast enhanced power Doppler ultrasonography (PDUS)for the detection of residual tumor in hepatocellular carcinomas (HCCs) treated by transcatheter arterialchemoembolization (TACE). MATERIALS AND METHODS: Fourteen nodular HCCs (size range: 1 - 7.3 cm, mean: 3.5) intwelve patients treated by TACE, and on the basis of follow-up liver CT, thought to have a residual tumor, wereincluded in this study. Between July 1997 and April 1998, PDUS examinations were performed with a 2-4 MHz convextransducer before and after intravenous injection of a microbubble contrast agent (Levovist(, Schering AG, Berlin,Germany). Real-time power Doppler ultrasonographic images were recorded on videotape and representative imageswere color-printed. Tumor vascularity was analyzed on real-time images with regard to its presence or absence, andchanges, and two observers reached a consensus. The results were compared with those of other diagnostic tests(three-phase helical CT, conventional angiography, percutaneous biopsy, and/or surgical pathology). RESULTS: Contrast-enhanced PDUS revealed intratumoral vascularity in ten of 14 tumors, none of which showed vascularity onunenhanced PDUS. In the remaining four tumors, both unenhanced and enhanced PDUS showed intratumoral tumorvascularity, which in all cases was more pronounced on enhanced than on unenhanced PDUS. Other diagnostic testsrevealed residual tumors in eleven lesions. CONCLUSION: Microbubble contrast-enhanced PDUS was more sensitivethan non-enhanced PDUS in depicting vascularity within a residual tumor and could be a useful method for thedetection of residual tumor in HCCs treated by TACE.

PURPOSE: To assess the outcome of tunneled central venous catheter placement via the right internal jugular vein. MATERIALS AND METHODS: Between June 2001 and May 2002, 670 consecutive Hickman catheters were placed in 654 patients via the right internal jugular vein. The procedural complications arising and follow-up data obtained from May to July 2002 were evaluated. RESULTS: The technical success rate for catheter placement was 99.9% (669/670). Procedural complications were limited to eight cases (1.2%), including three pneumothoraces, one early migration of the catheter, one clinically unimportant air embolism, one catheter injury, one catheter kinking and one primary malpositioning in the azygos vein. Catheter dwelling time ranged from 1 to 407 (mean 107.1) days. During the follow-up period, 416 catheters were removed for various reasons: treatment had ended (n=334), patients declined treatment or their drug regimen was changed (n=16), late complications arose (n=53), or other circumstances intervened (n=13). Late complications included 44 cases of catheter-related infection (6.6%), five of catheter migration (0.7%), two of catheter occlusion (0.3%), one of thrombophlebitis (0.15%), and one of catheter-related right atrial thrombosis (0.15%). Only one instance of symptomatic venous thrombosis or stenosis was noted , namely the one case of thrombophlebitis. CONCLUSION: Because the incidence of subsequent symptomatic venous thrombosis or stenosis is lower, the preferred route for tunneled central venous catheter placement is the right internal jugular vein.

PURPOSE: To evaluate the safety and efficacy of Hickman catheter placement via the subclavian vein under fluoroscopic guidance with intravenous contrast injection. MATERIALS AND METHODS: During an eleven-month period, 187 Hickman catheters were percutaneously placed in 167 consecutive patients in an interventional radiology suite. Subclavian venous puncture was made with injection of contrast medium into the peripheral venous line. After subclavian venous access had been obtained, a subcutaneous tunnel was created using a peel-away sheath or a tunneler. The Hickman catheters were inserted through a peel-away sheath, the distal tip of which was at the junction of the right atrium and the superior vena cava. RESULTS: One hundred and eighty-six Hickman catheters were successfully placed; the one failure was due to an atomical tortuosity of the vein(0.53%). Complications included one case of subclavian vein occlusion (0.53%); three of line occlusion by thrombus (1.6%); one of oozing at the suture site (0.53%); six of infection or inflammation (3.2%); eight of natural removal (4.2%); one case of air embolism (0.53%) and two of malposition (0.1%). Major complications such as pneumothorax or arterial puncture leading to mediastinal hemorrhage did not, however, occur. CONCLUSION: The authors concluded that radiologic Hickman catheter placement offers advantages over traditional approaches in terms of safety, convenience, and time and cost savings.

The use of bioabsorbable fixation system for the craniomaxillofacial surgeon has become available for prevention of intracranial migration, growth restriction by metal implants in pediatric patients as well as palpability in patients of all of ages. Recently, the field of bioabsorbable fixation system was expanded and the bioabsorbable screws were used successfully in endoscopic brow lift surgery. We reviewed 6 cases in which bioabsorbable plates and screws were used in aesthetic genioplasty: one male and 5 female patients between 17 and 38 years of age. The fixation of repositioned bone segment in genioplasty was obtained by using plates composed of a copolymer, polyglycolic acid and polylactic acid(LactoSorb, Walter Lorenz Surgical, Jacksonville, Fla.). The fixation devices were evaluated with regard to satisfactorily rigid fixation at the time of procedure. The postoperative follow-up procedure evaluated clinical wound healing, infection, palpability of plates through the skin and its visibility on imaging technique. Our experience with bioabsorbable fixation system in aesthetic surgery has been very favorable and reliable, although prospective studies with a longer follow-up of a larger number of patients are desirable to confirm these findings.

BACKGROUND: To pass through the microcirculation, erythrocytes need to undergo considerable deformation. We performed an experiment to investigate the erythrocyte deformability in healthy adults and in patients with uncontrolled hypertension and controlled hypertension. METHODS: 5ml of whole blood is anticoagulated with 2mg ethylenediaminotetra-acetic acid(EDTA). 1ml graduated plastic syringe, without its plunger, is filled with anticoagulated whole blood to the 1ml mark, And the syringe is put into the assembled membrane holder. Under standard condition, whole blood is passed through a 5micro polycarbonate membrane filter under negative pressure of 20cm H2O. The studies are performed at roon temperature and within two hours of venipuncture. RESULTS: Erythrocyte deformability was observed in 91 normal healthy adults and 25 patients with uncontrolled hypertension and 18 patients with controlled hypertension. Following results were obtained. 1) In male control age group I, II, III, the erythrocyte deformability indices were 0.776+/-0.125, 0.792+/-0.189, and 0.714+/-0.172 respectively and in female the indices were 0.880+/-0.138, 0.865+/-0.182 and 0.796+/-0.170 accordingly. 2) THe RBC deformability indices in female control troup were significantly higher than the male group in statistics(p<0.05). 3) No significant differences were observed among each age group in control. 4) In patients with uncontrolled hypertension, each age group I, II and III, the erythrocyte deformability indices were 0.785+/-0.050, 0.775+/-0.122, and 0.692+/-0.133 respectively and in control group, the indices were 0.8365+/-0.140, 0.8252+/-0.186 and 0.7534+/-0.173 accordingly. And in patients with controlled hypertension, the indices were 0.820+/-0.00, 0.788+/-0.135 and 0.716+/-0.141 accordingly. 5) The erythrocyte deformability inddex in patients with uncontrolled hypertension were significantly lower than the control group(p<0.05), and no significant differences were observed among each age group between male and female in patients with uncontrolled hypertension. 6) There was no significant statistical difference of deformability indices between uncontrolled group and controlled group(p>0.05). CONCLUSION: This study reveals that the erythrocyte deformability in patients with essential hypertension is significantly lower than the healthy adults.

Cardiovascular respons follwing ethanol ingeation was conapared in two groups of male college studenta; 20 who ahowed visble facial flushing and 25 whe showed on flushing. Ethanol was administered as 25% Korean liquor (Kumbokju) a dose of 2ml per kg body weight, the heart rate, blood pressure and respiratory rate were measured. The reaults areas follows. The heart rate after ethanol ingestion increased significantly in both flushing and non-flushing groups. However, the degree of the heart rate increased in the flushing group was aignificantly higher than that in the non-flushing group. The blood pressure was decreased significantly from 40minutes after ethanol ingestion in both groups. Howyer, the flushing group showed higher systolic pressure, and lower diastalic pressure and mean arterial pressure than the non-flushing group. The reapiratory rate following ethanol administration was increased in the flushing group but decreased in the non-flishing group when compared with the resting respiratory rate. The results clearly indicate that a signifcant difference in cardiovascular resoponrses to ethanol exists the flushing and non-flushing groups. The flushing group shows a greater tachycardia and greater fall in. mean arterial pressure followig ethanol ingestion than the non-flushing group.
