BACKGROUND: To prevent the platelet refractoriness, repeated plateletpheresis is often required in HLA matched single-donors. Korean Transfusion Standard permits the repeated plateletpheresis of a single donor at 72-hour intervals. To evaluate this standard, hematological responses of donors were assessed after plateletpheresis by Haemonetics V50 (Haemonetics Co., USA). METHODS: The pre- and post-donated hematological indices of 22 healthy donors(17 males and 5 females) were evaluated. Single donated donors were 12 males and 4 females. Multiple donated donors were 5 males and one female. Post-donated platelet counts were measured immediately, 6 hours, 12 hours, 1 day, 3 days, 5 days, 7 days and 9 days after plateletpheresis. Platelet aggregation test, serum protein, PT, and aPTT were also examined before and after platelet collection. RESULTS: Only 9 (56.2%) of 16 single-donated donors and 4 (66.7%) of 6 multiple donated donors showed normal restoration up to 97% of platelet counts of pre-donation levels at the day 3. In 9 (75%) of 12 single donated males restoration of platelet count was observed within 3 days, but 3 (75%) of 4 single donated females showed restoration of platelet count within 5 days. Changes of other indices were not significantly different between the pre- and post-donations of platelet. CONCLUSIONS: Although no clinical complication was noted after plateletpheresis, these data suggested that Korean Transfusion Standard on plateletpheresis should be reconsidered.

In spite of recent introduction of such highly sophisticated diagnostic modalities as computerized tomography,cardioangiography and polytomography the simple PA chest remaines as an essential and important method of chestdiagnosis especially in terms of vascular diseases of the lung and heart. Until recently, however, theinterpretation of chest x ray has been largely dependent on much subjective observation of roentgen anatomy of thechest. Several years ago Simon proposed a quantitative approach to interpretation of the chest in an attempt tomake the judgement more objective. In the present study we have carried out a clinical study on normalities of thestandard PA chest of Korean adults. The materials consisted of 216 normal chest films. Age ranged from 20 to 60years and sex distribution 103 males and 113 females, We counted the number of vessels in both lung fields,measured the diameter of the basal artery and investigated the level of hilum points as well as hilar distance.There were 9 to 11 vessels in the upper zone and 9 to 12 in the lower zone. There were no significant sexdifference. The number of vessels was not affected by aging. The average diameter of the basal artery was11.7±2.4mm in the right lower zone and 10±1.8mm in the left lower zone in female. There was significant sexdifference (p 0.01). Aging seemed not to be affected the size of the basal artery. The majority of hilum point waslocated at the level of 5-6th rib at axillary portion and the left hilar point is 0.3-2.0cm higher in locationthan the right. The hilar distance was 4.1±0.4cm on the right 5.0±1.1cm on the left in male and 4.0±0.7cm onthe right and 4.7±0.5cm on the left in female. There was significant sex difference (p 0.01). There wassignificant difference in size of the basal arteries and hilar distance between the Koreans and Englishmen but thenumbers of vessels were not significantly different.

PURPOSE: To evaluate the usefulness of CT for the diagnosis and treatment planning of mechanical intestinal obstruction. MATERIALS AND METHODS: We retrospectively reviewed 38 patients who were clinically suspected of mechanical intestinal obstruction and had undergone abdominal CT. The CT scans were evaluated for the absence or presence, severity, cause and site of intestinal obstruction. CT findings were compared with the results of laparotomy, barium study and clinical course. The absence or presence and severity of intestinal obstruction were classified into no obstruction, partial obstruction, complete obstruction. Diagnosis was estabilished by means of laparotomy in 20 cases, barium study in 9 cases and clinical course in 9 cases. RESULTS: Of 38 cases, 7(18.4%) showed no obstruction, 22(57.9%) showed partial obstruction, and 9(23.7%) showed complete obstruction. The presence or absence and severity on CT scans were corretly predicted in 36 of 38 cases (sensitivity 95%, specificity 97%, accuracy 96%) (in case of no obstruction:sensitivity 100%, specificity 94%, accuracy 95%;in case of partial obstruction:sensitivity 91%, specificity 100%, accuracy 95%;in case of complete obstruction:sensitivity 100%, specificity 100%, accuracy 100%). All 9 cases with complete obstruction underwent prompt and immediate laparotomy. 13 cases, excluding those with mass around the site of transition and adhesion with strangulation, with partial obstruction improved with conservative treatment without laparotomy. The causes of obstruction were adhesion in 13, hernia in 6, primary cancer in 5, metastatic cancer in 3, abscess in 2, intestinal tbc in 1, and Crohn's disease in 1. The cause of obstruction on CT scans were correctly predicted in 27 of 31 cases (87.1%). The sites of obstruction on CT scans were correctly predicted in 22 of 26 cases (84.6%). CONCLUSION: CT is valuable in the evaluation of absence or presence, severity, cause and site of intestinal obstruction, and is considered to be helpful in treatment planning for the patients with intestinal obstruction.

PURPOSE: The purpose of this study was to investigate the correlation between acculturative stress and depression of Vietnamese immigrant workers in Korea. METHODS: The subjects were 230 Vietnamese immigrant workers residing legally in B or K City. Data were collected from July 12, 2014 to August 3, 2014, and were analyzed using the SPSS PASW 21.0 program. RESULTS: The average level of acculturative stress was 2.91 and there were significant differences in the score according to whether to have a religion, the number of homeland friends, and Korean language skill. The average depression level of the subjects was 15.3 and the level was different significantly according to whether to have a religion, the number of homeland friends, salary, working hours, and Korean language skill. Acculturative stress and depression showed a significant positive correlation with each other. The influencing factors of depression were acculturative stress and the number of homeland friends. The most significant factor was acculturative stress. CONCLUSION: This result shows the necessity of various programs to diminish acculturative stress to control the depression of immigrant workers.

PURPOSE: We analyzed the clinical outcome of osteosarcoma developed in distal radius and the effect of delayed treatment on prognosis. MATERIALS AND METHODS: Twelve patients with distal radius osteosarcoma were analysed. We categorized patients into two groups of standard treatment or non-standard treatment. The patients of standard treatment group are all stage IIB and non-standard treatment group includes five stage IIB and one stage III. RESULTS: Five-year overall survival and disease-free survival rates of standard treatment group were 100% and 83%. Five-year overall survival rate of non-standard treatment group was 44%. Between two group, there are differences in age, tumor size, surgery type, symptom duration. CONCLUSION: Distal radius osteosarcoma have good prognosis than other extremity osteosarcoma. Survival rate of non-standard treatment group were lower than standard treatment group. Although the prognosis of non standard treatment group is poorer, the duration till death was longer than that of other sites with similar condition. Further multi-institutional study should be needed.

Recently MRI has been shown to be a sensitive and specific study for the noninvasive detection of meniscal tears and several MRI findings of bucket-handle meniscal tears have been reported. Therefore, the MRI findings of the menisci proven to be the bucket-handle tear with arthroscopy were evaluated and the typical MRI findings seen to be the bucket-handle meniscal tear of the knee were analysed. 76 patients with proven bucket-handle meniscal tears arthroscopically were reviewed retrospectively, in which MRI was performed in 24 patients. The 3 typical findings of bucket-handle meniscal tears were assessed: double PCL (posterior cruciate ligament) sign, flipped meniscus sign, and fragment in the intercondylar notch. In 245 cases of meniscus tears, bucket-handle meniscal tears were 76 cases (31.0%) with 52 cases at medial meniscus and 24 cases at lateral meniscus. As to clinical and physical findings of the bucket-handle meniscal tears, McMurray test, locking, joint line tenderness and giving way sense were presented in orders. The sites of bucket-handle meniscal tear were medial meniscus in 17 cases and lateral in 7 cases. The double PCL sign was seen in 10 cases (58.8%) of in medial bucket-handle meniscal tears and in 3 cases (42.9%) of 7 lateral bucket-handle meniscal tears. The flipped meniscus sign were seen in 3 cases (17.6%) of medial bucket-handle meniscal tears and in 3 cases (42.9 %) of lateral bucket-handle meniscal tears. Fragments were identified in the intercondylar notch in 8 cases (47.1%) of medial bucket-handle meniscal tears and in 3 cases (42.9%) of lateral bucket-handle meniscal tears. There were 19 cases (79.2%) in which at least one or more typical findings were presented on MR images. The MRI is a sensitive study for detection of bucket-handle meniscal tears but precise interpretation of MRI is needed for diagnosis of bucket-handle tears. In this respect, the above three typical findings are helpful and reproducible for diagnosis of bucket-handle meniscal tears with MR images; double PCL sign, fragment in the intercondylar notch and flipped meniscus sign.

In evaluating the esophago-gastric junction, many difficulties are well known in a single contrast study, andit may often be resolved with double contrast technique. By double contrast technique, the special en face viewfor the esophago-gastric junction was obtained in 298 cases at Inje Medical College Paik Hospital from Jan. 1981 to June 1981. Five basic patterns were recognized and classifed from type I to V. Their incidences were obtained.-type I ; 18%, type II; 50%, type III; 23% type IV ; 7%, type V; 2%. The most common position of patients is left lateral, and zero degree is the most common at elevation of fluoroscopic table. Type III is the most common typeof the esophage-gastric junction in inspiration, and type I expiration. Any significant deviations from thesenormal geometry of the esophago-gastric junction as displayed by double contrast study, indicate an abnormality.More special attentions are required to evaluate a minute pathologic condition of the esophago-gastric junction.
