This study was conducted to compare the date on knowledge, attitude and motivation toward blood donation between donors and non-donors. The study population included 622 donors and 322 non-donors who visited the mobile blood donation car of Taegu Red Cross Blood Center and participated the group appointed blood donation campaign managed by the center from March 1 to March 31, 1989. The donors and non-donors were questioned above mentioned items with a formulated questionnaire. Among the general characteristics of the subjects in the study, male predominance (84.1% in donors and 73.6% in non-donors) in young age group (16-24 years) was the outstanding feature. As a medium of information about blood donation, “television” was playing a dominant role (donors; 75.2%, non-donors; 78.9%), while “magazine” played more important roles among donors. Of the donors, 70.6% and of the non-donors, 58.1 replied that they had ever been induced to donate blood (p<0.01). Major inducers were friend and personnel of mobile blood donation vehicle. On the measuring of knowledge level, the average rates of correct answer was higher in donors (62.6%) than in non-donors (54.1%) (p<0.01). Higher the education level was presented, higher the knowledge level (p<0.05). There have been noticeable difference between donors and non-donors in blood replying the questionnaire set to measure their attitude toward blood donation, especially in the items such as “impression toward blood”, “selection of transfusion blood source” and “view on the situation of blood shortage.” The major motivation toward blood donation of the groups were “possible future need” and “altruism or humanitarian interest”. The major reasons for not donation blood in both groups were “fear of the needle” and “dread to visit to mobile car or center”.

PURPOSE: The aim of this study was to investigate the effects of extracorporeal shock wave therapy (ESWT) an lateral epicondylitis of the elbow. MATERIALS AND METHODS: Twenty-four patients with refractory lateral epicondylitis were treated with shock waves. The patients were evaluated by assessing of pain using visual analog scale (VAS) and a simple elbow test (SET). Overall clinical outcomes were evaluated using Roles and Maudsley scores at 12 months after ESWT. RESULTS: Significant symptom improvement were observed in 20 (83%) patients at the 12 months follow up according to the Roles and Maudesley scores. Average SET and VAS scores were also significantly improved after ESWT (p<0.05). CONCLUSION: This study suggests that shock waves therapy could be considered as an effective and noninvasive treatment modality for refractory lateral epicondylitis of the elbow.

PURPOSE: The purposes of this study were to evaluate the stress distributions and the displacements of obturator for edentulous maxillectomy patients and to compare them with those of complete denture using three-dimensional finite element analysis. MATERIALS AND METHODS: Based on the CT image of edentulous patient, three-dimensional finite element model of edentulous maxillae was constructed. Three-dimensional finite element model of edentulous maxillae with palatal defect was also fabricated. On each model, complete denture and obturator prosthesis were created. Vertical static force of 200 N was applied on the left maxillary premolar and molar region. The von Mises stress values and the displacements of models were analyzed using three-dimensional finite element analysis. RESULTS: Maximum von Mises stress values were recorded in the cortical bones of both models. The von Mises stress value in the complete denture model was 2.73 MPa and 2.69 MPa in the obturator model. High von Mises stress values were also observed on the tissue surface of prosthesis. The maximum value of the displacement in the obturator was higher than that of complete denture. CONCLUSION: The obturator showed a worse result in terms of stress distribution and displacement than complete denture. In the prosthodontic rehabilitation of edentulous maxillectomy patient accurate impression procedure based on patients' anatomy and application of prosthodontic principle should be considered.

Dermatomyositis (DM) is a connective tissue disorder characterized by inflammatory myopathy and prominent cutaneous features. Although cutaneous vasculitis has been noted frequently in child-onset DM, it rarely occurs in adult-onset DM. The clinical features of adult-onset DM showing cutaneous vasculitis have not been well characterized. A 60-year-old female patient presented with multiple deep cutaneous ulcers in both hands, elbows and foot. She was diagnosed as dermatomyositis 18 months before admission. Angiogram showed no definite arterial obstructive lesion and thrombus in both wrist and elbow, but decreased vascularity was seen in digits of both hands. Cutaneous ulceration was thought to be caused by vasculitis. Cutaneous ulceration was a rare manifestation of adult-onset DM patients, and we report this case with a review of literature.

Recently, it becomes conspicuous that the network should have enough communication bandwidth and be organized with steadiness to operate and support hospital information system successfully. Seoul National University Hospital completed to reconstruct legacy network which had been used since 1995. We had a consultation to diagnose the current problems and reconstructed the network according to the consultation. The design of network architecture was mainly focused on the circuit route in case of error condition and the suitable bandwidth for the easy communication. We also regulated the use of unsuitable protocols which might broadcast inappropriate data packets over the whole network. After 6 months of operation we evaluated the performance of newly constructed network. The average traffic rate from the input port of main servers was 0.5% and that from the output port was 6% separately. The average traffic rate on the overall ATM backbone showed around 1 %.From the result, we concluded that the newly constructed network had such an enough capability supporting hospital information system without any interruption. Furthermore, we expect that it will be sufficient to support the additional traffic increment by PACS and group ware applications.

BACKGROUND: The optimal immunosuppressive strategy for renal transplant recipients at high immunological risk requires clarification. We compared the 3 year outcomes of a sirolimus group (tacrolimus plus sirolimus) to those of a control group (tacrolimus plus mycophenolate mofetil). METHODS: This observational study was an extension of a prospective pilot study. We assessed acute rejection, glomerular filtration rate, adverse events, graft, and patient survival. RESULTS: Overall, 43% of the sirolimus group versus 78% of the control group were still on the initial immunosuppressive regimen at 3 years (P=0.005), and most discontinuations in each group were due to adverse events. No differences were observed between two groups with respect to acute rejection. The mean glomerular filtration rate at 36 months was greater in the sirolimus group than in the control group, but this was not statistically significant (64.0±6.8 mL/min/1.73 m² vs. 61.8±17.1 mL/min/1.73 m², P=0.576). Graft and patient survival were similar in both groups. Importantly, mean tacrolimus through levels were significantly lower in the sirolimus group than in the control group at each time point. No neoplasm was reported in the sirolimus group. In the control group, three cases of neoplasms developed during the study period. CONCLUSIONS: The sirolimus group had a greater number of discontinuations, particularly related to adverse events. Nevertheless, optimal concentration of sirolimus allowed reduced calcineurin inhibitor exposure in high immunologic risk patients, without increasing the risk of acute rejection and graft failure.

Several different tumors in different tissues(including the central nervous system, heart, kidney, liver, bone, and soft tissues) are found to be associated with tuberous sclerosis. In the brain, this tumor characteristically arises from the floor of the lateral ventricle and often occluded the foramen of Monro. Cardiac tumor is among the earliest signs of tuberous sclerosis and occurs in over half of affected patients, but symptomatic primary heart tumors are rare in newborn. Thus, early detections are rare in asymptomatic cases. We experienced a case of tuberous sclerosis, in a 2-day-old female newborn who presented with dilatation of lateral ventricle detected by fetal ultrasonography. Diagnosis was confirmed by brain MRI and echocardiogram demonstrated multiple cardiac tumor. Brief review and related literatures were also presented.

Immunoglobulin G4-related disease (IgG4-RD) can involve any organ. The majority of reported cases involve IgG4-RD of the biliary tract or pancreas, while only two cases of pericarditis have been reported. A 58-year-old man visited the outpatient clinic of our institution with a seven-day history of progressive dyspnea. Based on his transthoracic echocardiogram and transesophageal echocardiogram, he was diagnosed with constrictive pericarditis. The histopathology of his pericardiectomy revealed the cause of constrictive pericarditis to be IgG4-RD. Prednisolone (40 mg) was initiated after the pericardiectomy. As the patient's symptoms resolved, he was discharged and followed-up on an outpatient basis. This is the first case report of constrictive pericarditis caused by IgG4-RD in Korea.
