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: We evaluated the therapeutic results of intercondylar fractures of the distal humerus that were treated through the modified tricepssparing approach. MATERIALS AND METHODS: From February, 1997 to september, 2001, we reviewed sixteen cases of intercondylar fracture of the distal humerus, which were treated by surgical treatment. The follow up period ranged from one year to three years, averaging 1 year 8 months. The articularsurface of the distal humerus was exposed through elevation of the triceps from the medial and the lateral intermuscular septum. Theulna nerve was identified and protected, and then, the fracture sites were fixed with double plates. The functional results were evaluated using Broberg and Morrey's functional scale. RESULTS: All united at 14.5 weeks in an average. The functional results were as follows; three excellent, ten good, two fair and one poor. The range of the elbow joint motion was flexion contracture 11 degree to further flexion 130 degree in average. The one patient presented poor result had coronal shear fracture of the capitulum combined with severe comminution. The incomplete ulnar nerve palsy developed in one case. CONCLUSION: The modified triceps sparing approach provided sufficient exposure for rigid fixation of intercondylar fracture of the humerus. But in cases with severe comminution or coronal shear fracture, additional anterior approach or olecranon osteotomy should be considered.

OBJECTIVE: Pterional craniotomy (PC) using myocutaneous (MC) flap is a simple and efficient technique; however, due to subsequent inferior displacement (ID) of the temporalis muscle, it can cause postoperative deformities of the muscle such as depression along the inferior margin of the temporal line of the frontal bone (DTL) and muscular protrusion at the inferior portion of the temporal fossa (PITF). Herein, we introduce a simple method for reconstruction of the temporalis muscle using a contourable strut plate (CSP) and evaluate its efficacy. MATERIALS AND METHODS: Patients at follow-ups between January 2014 and October 2014 after PCs were enrolled in this study. Their postoperative deformities of the temporalis muscle including ID, DTL, and PITF were evaluated. These PC cases using MC flap were classified according to two groups; one with conventional technique without CSP (MC Only) and another with reconstruction of the temporalis muscle using CSP (MC + CSP). Statistical analyses were performed for comparison between the two groups. RESULTS: Lower incidences of ID of the muscle (p < 0.001), DTL (p < 0.001), and PITF (p = 0.001) were observed in the MC + CSP than in the MC Only group. The incidence of acceptable outcome was markedly higher in the MC + CSP group (p < 0.001). ID was regarded as a causative factor for DTL and PITF (p < 0.001 in both). CONCLUSION: Reconstruction of the temporalis muscle using CSP after MC flap is a simple and efficient technique, which provides an outstanding outcome in terms of anatomical restoration of the temporalis muscle.

Intraosseous lipomas are extremely rare and this incidence has been reported to be less than one per 1,000 primary bone tumors. Because of its rarity, information of this tumor is obtained from case reports. We report a case of intraosseous lipoma that developed in the proximal humerus. The patient was a 69-year-old male who had experienced night pain and intermittent pain at the proximal humerus for 10 years. Simple x-ray revealed a well demarcated osteolytic lesion, which was measured 4 cm in width with a central calcific lesion. There was no cortical destruction in the proximal humerus. He was treated by currettage without bone graft, thereafter his symptoms were relieved.

Background and Objectives:
This study aimed to investigate the association between cardiovascular events and 2 different levels of elevated on-treatment diastolic blood pressures (DBP) in the presence of achieved systolic blood pressure targets (SBP).
Methods:
A nation-wide population-based cohort study comprised 237,592 patients with hypertension treated. The primary endpoint was a composite of cardiovascular death, myocardial infarction, and stroke. Elevated DBP was defined according to the Seventh Report of Joint National Committee (JNC7; SBP <140 mmHg, DBP ≥90 mmHg) or to the 2017 American College of Cardiology/American Heart Association (ACC/AHA) definitions (SBP <130 mmHg, DBP ≥80 mmHg).
Results:
During a median follow-up of 9 years, elevated on-treatment DBP by the JNC7 definition was associated with an increased risk of the occurrence of primary endpoint compared with achieved both SBP and DBP (adjusted hazard ratio [aHR], 1.14; 95% confidence interval [CI], 1.05–1.24) but not in those by the 2017 ACC/AHA definition. Elevated ontreatment DBP by the JNC7 definition was associated with a higher risk of cardiovascular mortality (aHR, 1.42; 95% CI, 1.18–1.70) and stroke (aHR, 1.19; 95% CI, 1.08–1.30). Elevated on-treatment DBP by the 2017 ACC/AHA definition was only associated with stroke (aHR, 1.10;95% CI, 1.04–1.16). Similar results were seen in the propensity-score-matched cohort.
Conclusion
Elevated on-treatment DBP by the JNC7 definition was associated a high risk of major cardiovascular events, while elevated DBP by the 2017 ACC/AHA definition was only associated with a higher risk of stroke. The result of study can provide evidence of DBP targets in subjects who achieved SBP targets.

PURPOSE: Dexrazoxane has been used as an effective cardioprotector against anthracycline cardiotoxicity. This study intended to analyze cardioprotective efficacy and secondary malignancy development, and elucidate risk factors for secondary malignancies in dexrazoxane-treated pediatric patients. MATERIALS AND METHODS: Data was collected from 15 hospitals in Korea. Patients who received any anthracyclines, and completed treatment without stem cell transplantation were included. For efficacy evaluation, the incidence of cardiac events and cardiac event-free survival rates were compared. Data about risk factors of secondary malignancies were collected. RESULTS: Data of total 1,453 cases were analyzed; dexrazoxane with every anthracyclines group (D group, 1,035 patients) and no dexrazoxane group (non-D group, 418 patients). Incidence of the reported cardiac events was not statistically different between two groups; however, the cardiac event-free survival rate of patients with more than 400 mg/m2 of anthracyclines was significantly higher in D group (91.2% vs. 80.1%, p=0.04). The 6-year cumulative incidence of secondary malignancy was not different between both groups after considering follow-up duration difference (non-D, 0.52%±0.37%; D, 0.60%±0.28%; p=0.55). The most influential risk factor for secondary malignancy was the duration of anthracycline administration according to multivariate analysis. CONCLUSION: Dexrazoxane had an efficacy in lowering cardiac event-free survival rates in patients with higher cumulative anthracyclines. As a result of multivariate analysis for assessing risk factors of secondary malignancy, the occurrence of secondary malignancy was not related to dexrazoxane administration.

PURPOSE: Wilms tumor is the most common malignant renal tumor in children. We investigated the epidemiology, clinical features and treatment outcome of the children with Wilms tumor in Korea during the recent 10 years. METHODS: Two hundred forty six patients were enrolled between January 1991 and December 2000 from 26 major hospitals in Korea. The data regarding the clinical features including sex, age, pathologic type, prognostic factor and treatment outcome of patients were analyzed retrospectively by review of patient's medical records. Kaplan-Meier survival curves were constructed, The differences between groups were analyzed by log-rank test. RESULTS: There were 130 males and 116 females. The incidence between the age of 1~4 years was the highest with 66.2%. The annual incidence rate per 1, 000, 000 population varied from 1.9 to 2.1. The 10 years overall survival rate according to sex, clinical stage, pathologic type and relapse were as follows: 88.6% in male, 90.9% in female, 100% in stage I, 94.7% in stage II, 92.1% in stage III, 63.4% in stage IV, 85.7% in stage V, 95.3% in favorable histology, 64.1% in unfavorable histology, 94.8% in non-relapse, and 40.9% in relapse. The relapse rate was 12%. The 10 years overall survival rate of 246 patients were 89.1%. CONCLUSION: Our results could provide the most recent and important clinical information on Wilms tumor of children in Korea.
