Fatty tumours are,the most common soft tissue tumours whereas they are among the rarest tumours in bone. Dahlin quoted an incidence of 1 in 1, 000 of all bone tumours, and fatty tumours in bone are almost single intraosseous lipoma and of four types; I. Soft tissue lipomata or liposarcomata, secondarily affecting bone. 2. Parosteal lipomata. 3. Intraosseous lipomata. 4. Liposarcoma of bone. Here we report a case of multiple intraosseous lipomas in a 23 year old woman.

Ten cases of fracture of the carpal scaphoid analysed clinically and treated by admission at Department of Orthopedic Surgery, National Police Hospital during the period of 1975 to 1980. The results were summerized as follows: 1. The mode of the injury were consist of 3 in football game, 2 in judo, 2 in army training and 1 in fallen from height, 1 in slipping down, 1 in direct blow and almost falling down by outstretched hand. 2. Of the 10 cases, there were 9 male and 1 female patients. This result showed marked predominence of male over female patients and most commonly occured between 20 and 29 of age. 3. In 8 cases, the fracture was found on the waist of the carpal scaphoid. 4. Nonunion of the carpal scaphoid were noticed in 8 cases. 5. 2 cases of the recent fracture, there were appeared by rechecking X.-ray after 2 weeks. 6. The good results were obtained by bone graft according to method of Russe.

To identify the drug abuse status and its determinant factors in high school boys in Taegu, the study was performed from April to May, 1995. Study population were selected by cluster sampling method and total 5,665 students replied to the self-administered questionnaire survey(2,207 in academic high school, 3,458 in business high school). The major findings were as follows; The proportion of drinking, smoking experience was 55.0%, 45.8%, respectively, and the proportion of current drinker, current smoker was 27.2%, 27.5%. The drinking, smoking experience rate of second grade students was higher than first grade and it was higher in business high school boys. The proportion of a stimulant, a hallucinogen, hemp leaf cigarets experience was 3.2%, 1.6%, 0.1%, respectively. Drug abuse had significant association with home environment(lower economic status, frequent move, death of father or mother, apart from family), parents environment(parents' indifference, parents' drinking and smoking, etc.), school life(lower school grades, intimate friend's drug abuse, etc.), generous attitude to drug abuse, higher level of stress. Students who replied that the law prohibited immature person(students) from drinking and smoking showed lower drug abuse rate. In multiple logistic regression analysis, second grade students, business high school students, parents' indifference, lower school grades, intimate friend's drug abuse, no recognition of the fact that the law prohibits high school students from drinking and smoking, generous attitude to drug abuse, higher level of stress were significantly related with alcohol abuse and smoking. Other drugs abuse were related with above factors. On consideration of above findings, to prevent students from drug abuse, we have to try together in house, school, and society.

PURPOSE: The purpose of this study was to investigate the diametral tensile strength of polymer-based temporary crown and fixed partial denture (FPD) materials, and the change of the diametral tensile strength with time. MATERIAL AND METHODS: One monomethacrylate-based temporary crown and FPD material (Trim) and three dimethacrylate-based ones (Protemp 3 Garant, Temphase, Luxtemp) were investigated. 20 specimens (the empty set 4 mm x 6 mm) were fabricated and randomly divided into two groups (Group I: Immediately, Group II: 1 hour) according to the measurement time after completion of mixing. Universal Testing Machine was used to load the specimens at a cross-head speed of 0.5 mm/min. The data were analyzed using one-way ANOVA, the multiple comparison Scheffe test and independent sample t test (alpha = 0.05). RESULTS: Trim showed severe permanent deformation without an obvious fracture during loading at both times. There were statistically significant differences among the dimethacrylate-based materials. The dimethacrylate-based materials presented an increase in strength from 5 minutes to 1 hour and were as follows: Protemp 3 Garant (23.16 - 37.6 MPa), Temphase (22.27 - 28.08 MPa), Luxatemp (14.46 - 20.59 MPa). Protemp 3 Garant showed the highest value. CONCLUSION: The dimethacrylate-based temporary materials tested were stronger in diametral tensile strength than the monomethacrylate-based one. The diametral tensile strength of the materials investigated increased with time.

We herein describe a case of a 55-year-old healthy woman with localized primary thymic amyloidosis presented as a mediastinal mass, found incidentally by chest radiography. Computed tomography revealed a 4.1 cm soft tissue lesion with nodular calcification in the left anterior mediastinum. The resected specimen was a well-defined lobulating mass with calcification. Microscopically, the mass was consisted of amorphous eosinophilc hyalinized substances involving the thymus and intrathymic lymph nodes. These eosinophilic substances showed apple-green bi-refringence under polarized light after staining with Congo red. In immunohistochemical study, they were positive for kappa and lambda light chains and negative for amyloid A. There was no evidence of systemic amyloidosis in clinical investigations. A final diagnosis of localized primary thymic amyloidosis was made.

Acute epiglottitis is an inflammatory process of supraglottic region, which involving the epiglottis andhypopharynx region. This disease can be recognized easily radiologically and virtually all death are preventable.The lateral neck radiograph with soft tissuse technique is of critical value when the diagnosis is in doubt andusually characteristic when compared to the normal. Authors reviewed available lateral neck radiograph of 92 casesamong the 95 cases of clinically confirmed adult epiglottitis during 4 years in wallace Memorial Hospital. Theresults are as follows; 1. Male to female sex ratio was 13:2. 2. The most common age group was 4th decade. 3. Themost common clinical symptoms are sore-throat (87%) and dysphagia(87%). 4. The radiologic findings are swelling ofhypopharynx(92%), vallecular narrowing or obliteration (92%), uvula swelling (33%), narrowing of airway adjacentto epiglottis (17%), swelling of prevertebral soft tissue(8%).

Renal infarction with ethanol was induced exprimentally in rabbits and selective renal angiography wasperformed to evaluate the effectiveness of ethanol as embolic material. The results were as follows; 1. Completeobstruction of renal artery was produced in all cases within 1 week after injection of absolute ethanol(0.5ml/kg). 2. Incomplete obstruction of renal artery was produced in majority after injection of absolute ethanol(0.2ml/kg) and changed to complete obstruction above half cases with time. 3. Incomplete obstruction of renalartery was produced in minority after injection of 60% ethanol (0.2ml/kg) and complete obstruction of renal arterywas not produced. It was considered that ethanol is an effective agent for complete renal infarction and 0.2 to0,5ml/kg of absolute ethanol is effective dose for complete renal infarction.
