The authors reviewed 73 cases of ligament injuries in 70 patients from October, 1972 to June, 1978 who were admitted and treated in the Orthopedic Department at Kyung Hee University Hospital. Of 70 patients, the sex distribution was 59 patients (84%) in male and 11 patients (16%) in female. The high incidence was in age group from 21 to 40 years, that was 46 patients (55%). Traffic accident was most common cause of ligament injuries that was 61 patients (87%). Methods of treatment were direct repair, reconstruction and conservative treatment. Degree of angle and distance were measured with stress radiogram. Degree of angle and distance were also compared with normal and abnormal knee joints. Eleven cases were treated conservatively, and 62 cases, operatively, of whlch direct repair performed in 56 cases and reconstructive surgery, in 6 casea, The summary were as follows: 1. The result was better in the group with conservative treatment, as compared with operative treatment. And conservative treatment was applied only in single ligament injuries. 2. In normal knee joint, degree of angle was distributed evenly in the range of 0° to 10°, and distance was in the range of 0 to 10 mm. 3. In stress radiograrn, the significance of ligament injuries was present in more than 10° and 10 mm. 4. The measurement of distance seemed to be more meaningful than degree of angle. 5. It is helpful to measure the degree of angle and distance in diagnosis of ligament injuries, though not absolute.

Evaluation of a fever of unknown origin (FUO) is complex. Recently, PET scanning has been approved for screening in FUO evaluation. We treated three cases of FUO associated with increased FDG uptake in the bone marrow of the femur and tibia on the fusion PET/CT; all three had the same pattern of uptake. Bone marrow biopsies revealed mature lymphocyte and histiocyte infiltration and myxoid changes in one case, and cortical bone involvement in another case. The cases were all young females who had fever with neutropenia and relative lymphocytosis that lasted for several weeks and then remitted spontaneously. Even though the results of the studies were not diagnostic, the unique uptake pattern on PET/CT and the histology might be related to the cause of the illness and should be studied further to assess the association with classic FUO.

Regional left ventricular dysfunction is common in patients with coronary artery disease and accurate analysis of regional dysfunction is of particular interest. For the quantitative assessment of regional dysfunction, we measured regional ejection fraction by radial sector division method in 19 patients with acute myocardial infarction and 13 normal controls who had multigated blood pool scan. And two independent observer analyzed regional wall motion using 5 point grading system in 18 patients undergoing radionuclide ventricular cineangiography. The results obtained were as follows : 1) Regional wall motion scores for the gated blood pool study agreed completely in 72 of 108 segments (66.7%) and agreed within 1 grade in 88 of 108 segments(81.5%) and agreement rate is lowest in the septal area. 2) Global left ventricular ejection fraction was 63.2+/-4.2% in normal controls, 36.6+/-6.8% in extensive anterior wall infarction group and 52.6+/-9.7% in inferior wall infarction group. The value of extensive anterior wall infarction group was significantly lower than that of inferior wall infarction group(p<0.005). 3) Regional left ventricular ejection fraction by radial sector division method in normal control group were as follows : area 1 ; 56.5+/-6.7%, area 2 : 77.9+/-4.8%, area 3 ;84.3+/-5.5%, area 4 : 76.8+/-6.6%, area 5 ; 84.7+/-7.6%, area 6 ; 85.9+/-11.2%, area 7 ; 75.5+/-12.3%, area 8 ; 74.9+/-14.0%, area 9 ; 75.5+/-8.8%, area 10 ; 54.2+/-11.0%, 11 ; 34.5+/-16.3, area 12 ; 37.1+/-18.0%. 4) Mean regional ejection fraction in 7 patients with anterior wall infarction showed significantly lower values in area 4 to area 8, and in area 2 to area 5 in case of inferior wall infarction group. 5) We thought that regional ejection fraction obtained by radial sector division method is valuable index for the management and evaluation of patients with coronary artery disease.

Suicide is a major public health problem among Korean military personnel. As multiple factors and their interactions are related to suicide, multicomponent intervention might be useful for reducing suicide and suicide-related outcomes. The United States Air Force Suicide Prevention Program (AFSPP) launched in 1996 is a good example of an evidence-based multifaceted program focusing on leadership involvement and whole community-level efforts. For early identification and management of an at-risk population, AFSPP aims to encourage help-seeking and reduce stigma by changing the community's social norms regarding mental health and suicide. The present study reviewed the key elements of this successful intervention and made a proposal for improving the suicide prevention strategy in the Korean armed forces. This review might be useful for establishing a comprehensive intervention in local communities and organizations outside of the military.

Brunners gland adenoma is a benign epithelial tumor of the duodenum originating from submucosal Brunners gland. This is an extremely rare entity that account for only 10.6% of benign duodenal tumor, which are themselves relatively rare, representing 0.008% of all surgical and autopsy specimens. The clinical manifestation are nonspecific gastrointestinal complaints, such as bloating or epigastric pain, and the tumor gives rise to melena or anemia, due to the ulceration or erosion of the tumor. The diagnosis is usually made by radiologic studies and gastroduodenal endoscopy which can also provide definitive treatment. The aim of treatment is complete removal of the lesion and exclude malignancy. We report on 4 cases of Brunners gland adenoma which was confirmed by operation or endoscopic polypectomy.

In the recovery phase of acute myocardial infarction, residual ischemia is an important predictor of future cardiac event. To quantitatively evaluate the residual ischemia in the infarct zone and to see whether it can be predicted by particular coronary angiographic characteristics, dipyridamole stress SPECT 99mTc-MIBI myocardial scan was used in 31 patients with uncomplicated acute myocardial infarction. Quantitative assessment of residual ischemia in the infarct zone was made by the ratio of reversible defect in the polar display of SPECT MIBI scan to the total polar map area. Residual ischemia in the infarct zone in these patients does not correlate with patency, collateral circulation or jeopardy score of the infarct related artery. PTCA was performed in 7 patients with significant reversible defect and suitable anatomical lesion to evaluate the reversibility by revascularization. Following the PTCA mean reversible defect decreased significantly from 10.1+/-2.2% to 1.3+/-1.3%(P<0.05). In 10 patients with multivessel disease, 7(54%) out of 13 remote sites showed significant reversible defect showing limited usefulness in the detection of concomitant remote lesion in multivessel disease. Thus dipyridamole stress 99m Tc-MIBI myocardial scan is useful in the evaluation of residual ischemia in the infarct zone, and helpful in the decision making and assessing the result of revascularization.

BACKGROUND: To evaluate the efficacy, complication and restenosis rate of percutaneous transluminal coronary angioplasty(PTCA), we analized the results of PTCA for 277 cases(308 lesions) in 240 patients admitted to Seoul National University Hospital under the diagnosis of stable angina, unstable angina, acute myocardial infarction(AMI)or postinfarction angina between April 1986 and October 1991. METHODS: We performed PTCA with over-the-guidewire technique and followed up for 2-42 months(mean 16.2 months). To evaluate the clinical efficacy, patients without AMI and unstable angina underwent pre- and post-PTCA exercise test. RESULTS: Successful PTCA's were performed in 273 out of 308 lesions(88.6%). The success rate of PTCA for left anterior descending artery(LAD), left circumflex artery(LCX) and right coronary artery(RCA) was 88.5%(177/200), 88.9%(40/44) and 87.5%(56/64), respectively. Simultaneous PTCA for multiple coronary arteries were successfnlly perfomed in 26 out of 27 cases(96.3%). Success rate for individual coronary artery subtypes according to ACC/AHA PTCA subcommitte was 99.1% for type A lesions and 78.2% for type B lesions. Total exercise duration by treadmill test increased from 6.74+/-3.24min to 9.70+/-2.85min after PTCA(p<30.01). There were non-fatal acute coronary occlusions in 8 patients(3.3%), but there was no death related to PTCA nor emergency coronary artery bypass graft(CABG). During the follow-up period of 2 to 42months(mean : 16.2months), restenosis was suspected clinically in 90 patients, and was confirmed in 43 patients with coronary angiography. Among them, we performed second PTCA in 31 patients, and third PTCA in 2 patients. Seventy nine percent of restenosis developed within 6 months after PTCA. CONCLUSION: We conclude that PTCA was an effective and safe treatment modality for patients with coronary artery disease, especially when performed in patients with type A or B lesions and some of selected type C lesions.

In an effort to facilitate fabrication procedure of all ceramic crowns, a novel preparation method for all ceramic crown using alumina tape was developed. The alumina tape having a uniform thickness was cast by using Doctor blade method. The physical properties of newly introduced alumina tape has biaxial flexure strength of 500.600 MPa. The value of toughness is 3.18~3,28 MPa.m(1/2) which corelates with facture and the linear shrinkage rate of the alumina tape is 0.44% during core production. The marginal fitness of the alumina tape all-ceramic restoration with 90degrees shoulder margin had average marginal discrepancy at 78.3micrometer and average marginal gap at 44.4micrometer. At the marginal preparation of 135degrees deep chamfer, the average marginal discrepancy at 82.1micrometer and the average marginal gap at 40.2micrometer had been reported. This fabrication procedure of all ceramic crowns with alumina tapes is easier and less technical sensitive for dental technicians. After restoration with new all ceramic crowns we followed the patients 2 years later, there were no complications as porcelain fractures or periodontal disease. We had good esthetic clinical results with new all ceramic crowns.
