Removal of leukocytes from blood components may prevent alloimmunization to leukocyte antigens, febrile nonhemolytic transfusion reactions, transmission of leukotropic viruses or bacteria, and graft-versus-host disease. New surface-modified fibrous polyester filters were evaluated; they require no special processing of blood components and can be used at the patient's bed-side. Pall RC100TM(Pall Co., USA) was used to filter 2 units of RBCs at a time for a total of 8 filtrations: mean red cell recovery rate was 88.7%, mean WBC removal rate 99. 99%, and mean residual WBC count after filtration 2.77x 10 5. Twelve units of apheresis platelets were filtered with Pall PL50TM(Pall Co., USA): mean platelet recovery rate was 90.7%, mean WBC removal rate 99.95%, and mean residual WBC count after filtration 6.99 x 10 5. This study indicates that these filters efficiently remove WBCs without significant loss of red cells or platelets and that this kind of filters can be easily used at the patient's bed side.

This study was conducted to evaluate the relations between alcohol intake and blood lipid level in a group of 1,138 Korean adult men, ages 20 to 69 years. Total number of each of a variety of drinks in the previous two weeks was obtained by questionnaire and converted into grams of alcohol consumed in a week. The levels of blood lipid such as Cholesterol, HDL-Cholesterol, Triglyceride and LDL-Cholesterol were examined by enzyme method. We also observed the effects of various variables such as age, body mass index, smoking, exercise and blood pressure on blood lipid level. The results obtained were as follows; 1. Average weekly alcohol intake was 129.0+/-167.4 gm and that of 30-39 age group was the highest as 149.3+/-170.4gm. 2. Levels of Cholesterol, Triglyceride and LDL-Cholesterol tended to increase with increasing age, but level of HDL-Cholesterol showed no significant relationship with age. 3. The positive linear regressions of alcohol intake on HDL-Cholesterol and Triglyceride were noted statistically significant. 4. Multiple regression analysis demonstrated that the effect of alcohol on HDL-Cholesterol and Triglyceride was statistically significant and the contribution rates were 5.0% and 0.8%, respectively. And, in the case of HDL-Cholesterol, the alcohol intake was the most significant independent variable.

Larsen's syndrome is a very rare deformity, which is characterized by multiple congenital dislocations with a characteristic facial abnormality. The authors experienced a case of typical Larsen's syndrome that had saddle nose, hypertelorism, high-arched palate, dislocation of the hip joint, subluxation of the knee joint, dislocation of both radial heads, equinovarus deformities of both feet and winged scapulae of both shoulders. The dislocated left hip joint was reduced surgically and the result was excellent.

Numerous operations have been described to treat the recurrent anterior dislocation of the shoulder, but no one procedure was accepted as the choice of operation. We perforemed 6 Bristow procedures and 5 combined Bankart and Putti-Platt procedures and examined six shoulders by arthroscope from sep. 1989 to Sep. 1992, and we analysed the pathologic feature and the results of them. The average follow-up period was 2.2 years. 1. There were 8 males and 3 females and their average age was 33.7 years. The mean age in initial dislocation was 28 years. 2. The number of recurrent dislocation before operation was 17.9 times and the average duration of the disease was 5.7 years. 3. The pathologic lesions observed in intraoperative field were Hill-Sachs lesion (72.7%), Bankart lesion (90.9%), and the erosion of the glenoid rim (54.5%). On arthroscopic examination of 6 cases, Hill-Sachs lesion was found in 4 cases, Bankart lesion was seen in all of 6 cases, and the erosion of the glenoid rim was observed in 4 cases. 4. The average range of the limitation of external rotation was 17.3 and its significant difference was not observed between 2 operative groups. 5. By Rowes rating sheet, 4 cases of 5 combined Bankart and Putti-Platt operations were excellent and 1 case was good. 6. In conclusion, combined Bankart and Putt-Platt operation was considered as a good surgical procedure in the treatment of recurrent anterior dislocation of the shoulder.

The clinical value of CT in the diagnosis of pelvic bone fractures is being explored. Conventional radiographic projections, including internal and external oblique views, although very helpful, often cannot provide sufficent jnformation to give a true sense of the fractures. CT conversely displays the anatomy in an axial plane, thereby providing the missing pieces of information and fascilitating classification of these fractures. From January 1983 to June 1986, 34 patients with pelvic bone fractures, admitted to Department of Orthopedic Surgery, Severance Hospital, were given both CT and conventional radiographs. Comparing the conventional radiographic findings with those of CT, the following conclusions were obtained. 1. For patients with multiple trauma who necessitate position changes during conventional radiography, no further change in position was required during CT. 2. CT clearly showed intraarticular loose bodies, anterior wall fractures of the acetabulum, and separations of the saicroiliac joint which were hardly detected on conventional radiographs. 3. CT permitted a better evaluation of the shape, extent, and degree of separation of fracture fragment, so it was very helpful in formulating the treatment plan. 4. Follow-up CT was helpful in evaluating the effectiveness of treatment.

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.
