Journal of the Korean Radiological Society 1981;17(3):500-506
59 cases of pancreatic ultrasonography, proven by clinically, radiologically or pathologically, were analyzedand the results are as follows; 1. Enchogenecity of pancreatic cancer was low echogenic in 27 cases, highechogenic in 2 cases and had similar echogenecity in 3 cases, compared with liver. 2. There were 10 cases of livermetastasis of pancreas malignancy and the metastasis was demonstrated in 7 cases by ultrasonography. Theechogenecity of liver metastasis was low in 6 of 7 cases. 3. In 14 cases of pesudocyst, inflammatory changes inthe portion other than pseudocyst were demonstrated in 5 cases. 4. The localized enlargement of pancreas head wasdemonstrated in 3 cases of pancreatitis of 10 cases.

This study was designed to evaluate the worth of preoperative chemoradiation therapy in the management of locally advanced rectal cancer. Between march 1993 and January 1997, 64 patients with adenocarcinoma of the rectum were treated with preoperative irradiation followed by operation by one surgeon at department of surgery, Chungnam national university hospital. Cancers were treated with high-dose radiation (45 to 54 Gy) with (group 2) or without (group 1) chemotherapy Preoperatively 64 Patients were analysed prospectively, of these, 15 cases were preoperative radiotherapy alone arm and 49 cases were preoperative radiotherapy plus chemotherapy arm. The average age of the patients were 56 years (range 38~67) in group 1 and 57 years (range 27~80) in group 2. Male to female ratio was 8 : 7 in group 1 and 30 : 19 in group 2. Most clinical stage of the primary tumor mass were 73 (80% in Group 1,96% in group 2), being palpated slightly fixed (40% in group 1, 43% in group 2) or fixed (13.3% in group 1, 24.5% in group 2). As to distance of tumor from anal verge, most patients ranged from 4 to 8 cm (53% in group 1, 63.3% in Group 2). Chemotherapy consisted of 2 cycles of 5-fluorouracil (500 mg/m2/day for S days) delivered as a continuous infusion or bolus therapy and low-dose leukovorin (20 mg/m2/day for 5 days). After six weeks resting period of radiation, definitive surgical approach was performed. Overall treatment related toxicity rate was similar in both group except erythema on perineal skin, which was more frequent in group 2 than in group 1. Most frequent postoperative complication was intestinal obstruction (7.8%) followed by wound infection (6.3%), but there was no significant difference between two groups. There was one case of postoperative mortality in group 2 patients at 44 days after operation due to pneumonia and sepsis combined with liver cirrhosis. Tumor depth was downstaged in 38.5% of group 1 and 70% of group 2 patients on preoperative CT staging, and nodal downstaging was more effective on the respect of postoperative pathological report. Overall recurrence rate was 38.5% in group 1 and 20.5% in group 2. Of these, failure occured first as a distant metastasis more frequently than as a local recurrence in both group. These data do suggest that the preoperative chemotherapy and radiotherapy used are as safe as preoperative radiotherapy alone. Futhermore, tumor and lymph node downstaging are more effective in combined arm. Preoperative chemotherapy will more promising in prevention of distant metastasis when treated in the period of least metastatic tumor burden. Whether combined arm will have greater or lesser survival awaits the completion of this relevant study.

Persistent burning and derythema were present for 10 months cin he lower lip of a 55-year-old woman, who had extreme melalignment of the anterior maxillary teeth. Candida albicans was identified not only from the surface material of the lower lip but also from tl.e malaigned dental cleft, which was thought to be the source of the organisms. We feel that the impor.ance of malaligned theeth as a source of candida albicans miist be kept in mind when we face persis ent cheilitis in a patient whose teeth arrangement is bad.

STATEMENT OF PROBLEM: Proper proximal contact is important for maintaining and stabilizing the dental arch. However, the proximal contact strength (PCS) is not a constant value and can be affected by a variety of factors. PURPOSE: This study examined the influences of postural changes on the posterior PCS. MATERIAL AND METHODS: Twelve adults with a normal occlusion and had not undergone prosthetic treatment or proximal restoration were participated in this study. A metal strip was inserted into the proximal surface and removed at a constant velocity. The contact strength was measured in every contact point between canine to second molar in both arches. The PCSs were obtained initially in the upright position, secondly in the supine position and finally in the upright position again. All measurements were repeated after a 2 hour period. Statistical analysis was carried out using the Friedman test (P < .05). RESULTS: Generally, a decrease in PCS occurred when the posture was changed from the initial upright to supine position, while it increased when the posture was changed from the supine to upright position. A significant change was observed in all areas except for between the canine-first premolar in the maxilla and between the first molarsecond molar in the mandible areas. CONCLUSION: The posterior PCS, which dentists generally believe to be a static feature of occlusion, is affected significantly by posture.

Bleeding from esophageal or gastric varix is the most critical and life-threatening complication of portal hypertension and the most common cause of deaths in the patients with cirrhosis. In the management of variceal bleeding, the various therapeutic interventions including operation and nonoperative procedure were tried, but neither of management was successfully achieved. Between February 1992 and November 1994, we performed endoscopic injection sclerotherapy(EIS) in 35 cirrhotic patients who had recently bled from esophageal varices and had a past history of esophageal variceal bleeding in Chonbuk National Univesity Hospital. Among 35 patients, 32 were male and 3 were female. The underlying severity of liver disease was graded A, B or C according to modification of Child-Pugh classification. EIS was repeated every 1 week until the esophageal varices had been complete obliterated and removed. To investigate the effects of esophageal varix eradication by EIS on combined peri- cardial varix, endoscopic examinations were performed both before procedure and after complete EIS sessions and this study was performed to examine a changes of combined pericardial varices after EIS procedure for the treatment of esophageal varices bleeding secondary to portal hypertesion. We reviewed medical records and compared changes or sizes of pericardial varices before and after EIS procedure. Mean follow up peiod was 61 days. Total number of 162 EIS for variceal eradication were performed. Mean session for eradication of esophageal varices was 4.6 per person, mean amount of injected sclerosant was 8.3cc(1-18cc), mean duration of EIS was 39 days, and mean follow up was 62 days after complete EIS procedure. In total 162 EIS procedure, complications associated with EIS including substernal discomfort 53.7%(n=87), substernal chest pain 45.7%(n=74), fever 4.9%(n=8), dysphagia 14.2%(n=23) and pleural effusion 3.1%(n=5), were transient and not required specific management. During the follow-up period, complete disapperance of pericardial varix or reduction of size was appeared in l8 cases(51.4%) among total 35 patients. No significant changes of variceal size before and after procedure were l6 cases(45.7%) and only 1 case(2.9%) was more aggravated. So, these results suggest that EIS procedure of esophageal varix on pericardial varix seems either to improve or to maintain the severity of the pericardial gastric varix without aggravation.

Pulmonary artery sling is an uncommon and potentially lethal vascular anomaly that can produce airway obstruction. Despite the availibility of a corrective operation, the mortality rate remains very high due to the high incidence of associated obstructive anomalies of the tracheobronchial tree. We experienced a 70-day-old male infant who was admitted to our unit because of sudden dyspnea, cyanosis, coarse expiratory wheezing and inspiratory stridor. At first, he was treated with bronchodilator and steroid under the impression of infantile asthma, but the symptoms went on without interval change. We performed magnetic resonance imaging study followed esophagography and two dimensional echocardiography. Finally he was diagnosed as a vascular sling. We report this with a brief review and related literatures.

PURPOSE: To evaluate the findings and the role of contrast enhanced magnetic resonance imaging in avascular necrosis of femoral head. MATERIALS AND METHODS: Sixteen patients with avascular necrosis of femoral head were examined with MRI. Tl-weighted and T2-weighted images and contrast-enhanced Tl-weighted images were obtained. Enhancing characteristics of the necrotic area and synovium were determined. Also a change of the disease extent after enhancement was assessed. RESULTS: Twenty seven avascular necrosis of the femoral head including 11 cases of bilateral lesion were detected. Fifteen cases revealed collapse of the femoral head. The portions of the lesion with low signal intensity on Tl-weighted images and high signal intensity on T2-weighted images showed contrast enhancement in 15 cases. However, the portions with low signal intensities both on T1 and T2-weighted images showed enhancement in one case. There was no significant change of the disease extent after enhancement. Synovium showed enhancement in 18 cases, and joint effusion was detected in 23 cases. CONCLUSION: Contrast enhanced MR images may be helpful in predicting histopathologic findings of avascular necrosis of the femoral head, but not useful for evaluating the extent of disease.

A fabrication method of inner and outer crown using CAD/CAM is presented. The information of abutment teeth is transferred to a computer through a 3-dimensional scanner. A Konus inner and outer crown is designed on a computer and a real crown is machined based on this design using CAM. This method can save laboratory time and reduce inaccuracies compare to conventional casting procedure. A stone model with six prepared abutment teeth from a patient was used in this study. Three dimensional information from the model was transferred to a computer using a contact type 3dimensional scanner with a 25micrometer accuracy. All margins were identified on a computer image where there is a change in surface taper of a model. To provide a cement space, the image of a inner surface of a Konus inner crown was duplicated 25micrometer apart from the surface of a prepared abutment teeth image. The cement space was 20micrometer at the cervical margin. All Konus crowns were machined with a 10micrometer accuracy. It was concluded that this method can reduce working-time for the laboratory process and increase accuracy. A further research is required to make a simplified process for a more complex prosthesis.
