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: Studies conducted on both animal and adult human subjects have demonstrated that a decrease in cerebral blood flow (CBF) causes cerebrocortical dysfunction resulting in an abnormal electroencephalogram (EEG). Although it is assumed that in premature infants with patent ductus arteriosus (PDA), the shunt will decrease CBF and alter the cerebrocortical function thus resulting in an abnormal EEG, this has yet to be firmly established. This comparative study, therefore, measures EEG as effected by CBF before and after PDA closures. Furthermore, in order to observe the effect of PDA on CBF and EEGs, the results were compared against a control group made up of premature infants without PDA. METHOD: All subjects were premature infants admitted to the neonatal intensive care unit of Chungbuk National University Hospital between February and August of 1997, were under gestational age (GA) 36 weeks, and weighed less than 2 kilograms: PDA group (group I consisted of 8 with PDA and respiratory distress syndrom (RDS); group II of 5 with PDA but without RDS) and Control group (group III of 6 without PDA but with RDS; group IV of 12 with neither PDA nor RDS). Studies were performed on the third and seventh day after birth and continued weekly throughout the period of study. Using Acuson 128XP/10c Doppler Echo cardiography, we measured the peak systolic velocity (PVS), the end-diastolic velocity (EDV) and the area under the velocity curve (AUVC) of the anterior cerebral artery (ACA), the blood flow of the left carotid artery and the descending aorta, calculated the LA/Ao ratio and conducted EEG's. RESULTS: 1) Birth weight and gestational age There was a significant difference between group I and group IV. However, when contrasting the two control groups overall, we found no significant variation. 2) In the PDA group, the infants were treated as follows: four infants were performed PDA ligations and seven were administrated indomethacine, resulting in 5 successful closures. Two infants had PDA which closed naturally without any treatment.3) PSV, DV, AUVC in the PDA group before and after closureThe incidence of decreased cerebral blood flow tended to increase after the PDA closure; however, the variation was not significant. In the groupes with RDS, on the other hand, the increase of CBF was significant after treatment, especially in group III.4) Incidence of abnormal EEGsThe preliminary EEG was abnormal for the above infants, with the background EEG appearing as suppressed or sharp and spike wave discharges. There was no significant difference in the results of the two groups and all EEG's were normalized in subsequent examinations. CONCLUSION: The decreased cerebral blood flow in premature infants with PDA increased following closure of the shunt; however, this increase was not significant. In groupes with RDS, the decreased cerebral blood flow significantly increased as the RDS improved, especially in group III. Nonetheless, despite the observed changes in CBF, we were unable to detect a corresponding change in the EEGs of the newborns in this study.

PURPOSE: A laparoscopic appendectomy (LA) is becoming popular for the treatment of acute and perforated appendicitis. Since it was first described, the LA has been modified many times. We present the result for a new technique of LA, in which the LA is conducted through a single umbilical incision without exteriorizing the appendix to perform the operation. METHODS: A single incision laparoscopic appendectomy was attempted in 25 patients (17 men, 8 women). Under general anesthesia, a wound retractor was inserted through the umbilicus. The appendix was grasped and dissected from surrounding tissues with a single flexible dissector or grasper. After mesenteric dissection with ultrasonic shear, the base of the appendix was ligated with an Endoloop. The appendix was withdrawn into the wound protector and extracted from the abdomen. RESULTS: A single incision laparoscopic appendectomy was completed in 25 patients. No major intraoperative or postoperative complications were encountered. The average duration of the procedure was 50.3+/-21.3 min. The average hospital stay was 4.1+/-2.4 days. CONCLUSION: This new technique, a single incision laparoscopic appendectomy, further improves the minimal invasiveness of a LA because a single incision is used. This procedure is a safe, very minimally invasive procedure with excellent cosmetic results.

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.

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.

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.

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.
