The majority of the radiologically detected solitary pulmonary nodules are benign, although relatively infrequent malignant nodules always make problems. Regarding the high prevalence rate of pulmonary tuberculosis in this country, it could be assumed that a large number of the benign pulmonary nodules are tuberculomas. There have been various attempts with CT in the evaluation of solitary pulmonary nodules. Most of them were focused on the nodule itself, however. We evaluated not only the character of the nodules bus also the parenchymal changes around the nodules to find evidences of associated pulmonary tuberculosis by using highresolution CT. We analyzed 35 benign solitary pulmonary nodules which are less than 4cm in size. Three or 5 high-resolution CT images were obtained in additon to the conventional CT images. Most of the nodules were located at the periphery of lung. Most of the nodules were proved to betuberculomas or presumed to be tuberculomas (n=32). The mean diameter of the nodules was 22mm. Most of the nodules were well-marginated. We observed a lobulated margin in 16 tuberculomas and a finely spiculated margin in 6 tuberculomas. Typical patterns of benign calcification were observed in 12 tuberculomas and one margin in 6 tuberculomas. Typical patterns of benign calcification were observed in 12 tuberculomas and one hamartoma. the findings of parenchymal tuberculosis such as interlobular septal thickening, small centrilobular micronodules, and lobular overinflation were identified in 12, 6 and 12 cases of tuberculomas respectively. The changes of juxtanodular lung parenchyma as well as the character of nodule itself were well demonstrated on high-resolution CT. which is valuabel I the evaluation of the equivocal solitary pulomnary nodules. Evidences of pulmonary tuberculosis around the nodule would be the secondary sign of benignancy.

BACKGROUND: We compared the clinical outcomes of cardiac valve surgery in adult Jehovah's Witness patients refusing blood transfusion to those in non-Jehovah's Witness patients without any transfusion limitations. METHODS: From 2005 to 2014, 25 Jehovah's Witnesses (JW group) underwent cardiac valve surgery using a blood conservation strategy. Twenty-five matched control patients (non-JW group) were selected according to sex, age, operation date, and surgeon. Both groups were managed according to general guidelines of anticoagulation for valve surgery. RESULTS: The operative mortality rate was 4.0% in the JW group and 0% in the non-JW group (p = 1.000). There was no difference in postoperative major complications between the groups (p = 1.000). The overall survival rate at 5 and 10 years was 85.6% ± 7.9% and 85.6% ± 7.9% in the JW group, respectively, and 100.0% ± 0.0% and 66.7% ± 27.2% in the non-JW group (p = 0.313). The valve-related morbidity-free survival rates (p = 0.625) and late morbidity-free survival rates (p = 0.885) were not significantly different between the groups. CONCLUSIONS: Using a perioperative strategy for blood conservation, cardiac valve surgery without transfusion had comparable clinical outcomes in adult patients. This blood conservation strategy could be broadly applied to major surgeries with careful perioperative care.

CT was found to be highly accurate in predicting tumor size and assessing invasion of the surroundingstructures and distant metastasis. Also CT played an important role for determination of operability of esophagealcarcinoma. The CT findings with barium esophagogram in 21 patients with histologically proven esophageal carciomawere reviewed from Feb. 1985 to Feb. 1986 at the department of Radiology, Yonsei University ,College of Medicine.The results were as follows: 1. Number of patients in each stages were: 2 in stage 1, 6 in stage 2, 4 in stage 3,and 9 in stage 4. 2. Peak age distribution was in its 6th decasedes as 9 patiens (42.9%). Overall mean age was 60.8 years. Number of male patients were 19 and 2 of female. 3. Histologic types of esohageal carcinoma were 19cases of epidermoid (90.5%) and 2 cases of adenocarcinoma(9.5%). 4. The tumor location was 1 case in upper, 14cases(66.7%) in middle and 6 cases in lower one-third. 5. Various types of esophageal carcinoma were as follows: 3cases of fungating, 4 cases of infiltrating, 5 cases of ulcerofungating, and 9 cases of ulceroinfiltrating type.6. Average length of involvement in each stages were 4cm in stage 1, 5.5cm in stage 2, 8.8cm in stage 3, and 8.3cmin stage 4. The involved length was longer in advanced cases. In 11 cases(52.4%), the involved length was between4 and 8cm. 7. Angle of periaortic fat plane obliteration of the aortic circumference were as follows: Below 45degrees( 7 cases 33.3%), 45degrees-90degrees (3 cases 14.3%), over 90 degrees(11 cases, 52.4%). 8. Method oftreatment of esophageal carcinoma were as follows: Only radiotherapy in 11 cases(52.4%), radiotherapy withoperation in 5 cases, only operation in 1 cases, and no treatment in 4 cases. 9. Distant metastatic sites were:brain in 1, pericardium in 5, liver in 5, trachea in 2, bronchus in 9, and distant lymph node in 5 cases.

19 years old female had untreated Veau classification class II cleft palate with ectopic eruption of upper right lateral incisor and congenital missing of lower lateral incisors. Upper left lateral incisor, left first molar aid lower left first molar were root restswithperiapicalpathologiclesions. So all root rests were extracted and prosthodontic rehabilitation after orthodontic treatment was planned. She was treated by means of multibanded system with face bow. After 23 months all orthodontic correction were achieved and, as soos as debanding procedure was done she was referred to oral surgeon and prosthodontist for surgical operation and bridge construction.
