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.

BACKGROUND: The purpose of this study is to obtain the accurate information on the obesity indices, such as body mass index(BMI), relative weight and waist-hip ratio(WHR) and to investigate their relationship in order to assess the childhood and adolescent obesity more appropriately. METHODS: In May, 1995, a total of 6943(male; 3469, female; 3474) students from primary, middle and high schools in Seoul were selected and each students height, weight, waist and hip circumference data were collected. RESULTS: The BMI increased with age in both sexes. From age 12 to 16, values of BMI 50th percentiles for females exceeded those for males. And the BMI 95th percentiles at the age of 13 to 14 years were higher for females than for males. The prevalence of obesity by relative weight was higher in males than in females(male ; 17.9%, female ; 13.1%). The WHR was higher in males than females in all age group and decreased with age in both sexes, showing more sharp reduction in females. Strong correlations were observed between the BMI and the relative weight, and the BMI and the relative weight correlated closely with WHR. The WHR was significanly higher in obese group' than in non-obese group. In the female obese group aged 6 to 11 years, no significant correlation was found between the relative weight and the WHR. CONCLUSIONS: There were significant relationships between the indices of obesity and body fat distribution. This study suggests that WHR as well as BMI and relative weight might be useful in assessing the childhood and adolescent obesity.

Polymorphic reticulosis(PMR) is a unique clinicopathological entity of unknown etiology, which commonly present as an aggressive, necrotizing lesion of the upper respiratory tract. It is a separate nosologic entity from Wegener's granulomatosis and idiopathic mildine destructive disease. The origin of the cells composing polymorphic reticulosis has been controversial. We reviewed 15 cases of polymorphic reticulosis with respect to clinical and histologic bases, and immunohistochemical studies were done using UCHLI (CD45RO), as a T cell marker, CD-20 as a B cell marker and alpha- I -antichymotrypsin as a histiocytic marker. Almost all cases showed characteristic histologic and immunohistochemical features similar to those of peripheral T cell lymphoma. Thus, this study indidcated that polymorphic reticulosis is a type of malignant lymphoma of T cell lineage.

Whole brain irradiation is one mode in the treatment of brain cancer and brain metastasis, but it might cause brain injury such as brain necrosis. It has been studied whether the dose distribution could be a cause of brain injury. The dose distribution in whole brain irradiated by Co-0 beam has been measured by means of calibrated TLD chips inserted in the brain of Humanoid phantom. The following results were obtained. 1. Dose distribution on each transverse section of the brain was uniform. 2. On the midsagital plane of the brain, the dose was highest in upper portion and lowest in lower portion, varying 8 from 104% to 90%. 3. When the radiation field includes free space of 2cm or more width out of the head, the dose distribution in the whole brain is almost independent of the field width. 4. It is important to determine adequate shielding area and to set shielding block exactly in repetition of treatment.

OBJECTIVES: Anticardiolipin antibody (ACA) and lupus anticoagulant (LA) are acquired antiphospholipid antibodies (APAs), which are regarded as important risk factors far vascular thrombosis and recurrent fetal loss. Although the clinical relevance of APAs in dialysis patients is uncertain, recent studies have suggested that APAs are involved in bioincompatibility and thrombogenic complications in hemadialysis (HD) patients. METHOD: We performed a cross sectional study of ACA and LA in 50 stable HD patients and their 68 vascular accesses (52 native arteriovenous fistulae and 16 synthetic arterovenous grafts), with the analysis of factors associated with the presence of APAs and the retrospective evaluation of vascular access occlusion (VAO). LA was assessed by platelet neutralization method whereas IgG-ACA was measured by a solid phase ELISA. Values higher than 23GPLU/ml (IgG phospholipid units) were considered to be positive for IgG-ACA and positive values for LA was more than 8 seconds in prolongation of the clotting time with human platelet lysate. Vascular access survival was assessed by Kaplan- Meier method, RESULTS: The mean age of the subject (M:F 21:29) was 46 years and the mean duration of hemodialysis was 49 months. The frequency of VAO in entire subjects was 0.45+/-0.98 episodes/patient year. The median value of IgG-ACA was 16.0 GPLU/ml with a distribution from 2.7 to 46.1GPLU/ ml. The median titer of I.A was 4.5 (3.1-45.6) seconds. Fourteen patients (28%) were found to have at least one episode of VAO. In spite of comparable clinical and biochemical data according to the presence of VAO, the titers of IgG-ACA (13.6+/-7.7 vs, 20.3+/-8.7GPLIJ/ml, P<0.05) and LA (4.5+/-2.9 vs. 11.7 +/-12.6sec, P<0.05) were significantly higher in VAO group. Six out of 50 patients(12%) had an increased titer of IgG-ACA and LA was found in 11 patients(22%). No patients were positive for ACA and LA simultaneously. There was no significant difference in sex, etiology of ESRD, diabetic status, the dosage of heparin during HD or the amount of erythropoietin administered according to the presence of APAs. We could not find any significant correlation between the titer of APAs and age, duration of dialysis, blood pressure, platelet count and biochemical parameters. In the patients with positive ACA, the frequency of VAO was 1.05+/-0.12 episodes/patient year, which was significantly higher than patients without ACA (0.33+/-0.17 episodes/ patient year, P<0.05). In the patients with the presence of LA(1.06+/-0.43 vs. 0.12+/-0.06 episodes/ patients year, P<0.01). The median vascular access survival time in IgG-ACA positive patients (32.7 months) was significantly decreased compared to 66.8 months in IgG-ACA negative group. CONCLUSION: Our data suggest that the presence of APAs (ACA and/or LA) affects the event-free vascular access survival in HD patients. Therefore the evaluation of APAs status have to be included in the diagnostic strategies for the patients with recurrent VAO. Further studies are necessary to explore the pharmacologic intervention method to decrease APAs and prevent VAO in HD patients.
