A clinical analysis of infective endocarditis was done in 34 patients who were admitted to National Medical Center from march. 1972 to June. 1984, and the results were as follows. 1) There was no difference in ratio between sexes. The prevalence was highest in the 3rd decade. 2) The important preexisting heart diseases were rheumatic heart disease(32.4%), congenital heart disease(17.6%) and undefined cardiac condition(20.6%) in order of frequency. 3) The common symptoms and signs on admission were fever(88.3%), cardiac murmur(79.4%), malaise(70.6%), dyspnea (64.7%), palpitation(55.9%) and hepatosplenomegaly(55.9%). 4) The positive blood culture was obtained in 15(47%) of the cases. Those who had not received antibiotics before admission showed higher rate of positive culture(72.7%) than in those who had received(33.3%). 5) The laboratary findings revealed anemia(73.5%), leukocytosis(35.3%), increased ESR(73.5%), microscopic hematuria(61.8%) and positive CRP(100.0%). 6) The EKG findings showed normal(11.8%), sinus tachycardia(32.4%), LV hypertrophy(29.4%), non-specific ST-T change(20.6%) and AV block(14.7%). 7) Vegetation was detected by echocardiography in 43% of cases and the most frequently involved valve was aortic(66.7%). 8) The combination of penicillin and aminoglycoside was effective in 86.4% of patients so treated.

Hemodialysis is a major mode of renal replacement therapy in children as well as CAPD. PermCath , a dual lumen silicone atrial catheter with a dacron cuff, has been used as vascular access for hemodialysis. Between Aug. 1, 1994 and Mar. 31, 1996, 29 children had been received PermCath catheter implantation for hemodialysis in the Department of Pediatrics, Seoul National University Children's Hospital. Their medical records were analyzed retrospectively. The mean age and weight of the patients were 9.8+/-4.6years (6months-17years) and 25.7+/-11.0kg (6.2kg-40kg), respectively. For short-term use (60days) users, mean life span of the catheter was 230.8 +/-158.6days (61-591days) and the actuarial catheter survival rate at 1 year was 44 %. The mean recirculation rate checked in 5 patients was 9.6+/-4.0%. The rate of thrombotic occlusion was 1.5/1,000 catheter days. Most of the clots except one could be lysed with local urokinase therapy. The rate of catheter associated fever was 0.6/1,000 catheter days. One catheter needed revision due to malposition and local bleeding developed during the procedure. PermCath catheterization was immediate, durable and relatively safe vascular access in childhood hemodialysis.

PURPOSE: The purpose of this study was to examine the academic achievement of the first year medical students at Gachon University of Medicine and Science based on their characteristics (i.e. age, gender, and academic degree types (bachelors/masters), field of major (biology/ non-biology), and admission variables (i.e. MEET, GPA, attitude, interview, and English test). METHODS: The admission scores and demographic information were obtained from 39 students who had entered the university in 2005. T-test was used to examine the differences in academic achievement according to the students' characteristics. Correlations between admission variables and academic achievements were examined while multiple regression analysis was used to decipher the influence of students' characteristics and admission variables on the academic achievements. RESULTS: This study showed that the academic achievements differed significantly depending on degree level, age, and field of study, but not gender. It was also found that both the Nature Science Reasoning (NSR) of MEET subscale score and GPA score correlated significantly with academic achievement in the first year students. Attitude, interview, and English test scores did not correlate significantly. The result of the multiple regression analysis revealed that NSR 1 and 2, field of major, and age accounted for a substantial amount of the variance in academic achievement. CONCLUSION: Students with higher scores in NSR 1 and 2 who majored in biology-related fieldsand who are younger tend to do better academically in their first year of medical school. The results of this study may be helpful to graduate medical schools in designing effective admissions strategies for recruiting students, as well as, in planning the curriculum to improve the academic achievements of medical students.

PURPOSE: Obesity is related to many diseases, including urological conditions. We investigated the prevalence, risk factors, and treatment of male obesity. MATERIALS AND METHODS: This study included 17,485 men older than 20 years of age who participated in the fourth, fifth, and sixth administrations of the Korean National Health and Nutrition Examination Survey. Two main cutoff points for obesity were defined: a body mass index (BMI) ≥25 kg/m2 and a BMI≥30 kg/m2. Additionally, we defined obesity requiring pharmacotherapy as the presence of a BMI≥30 kg/m2 or a BMI≥27 kg/m2 co-occurring with at least one associated comorbid medical condition, such as hypertension, dyslipidemia, or diabetes. RESULTS: The prevalence rates of a BMI≥25 kg/m2, a BMI≥30 kg/m2, and obesity requiring pharmacotherapy were 35.7%, 3.4%, and 10.5%, respectively. The prevalence of obesity increased over time for all definitions of obesity. The prevalence of obesity requiring pharmacotherapy was highest in Jeju (12.5%) and lowest in Gangwon-do (7.7%). Having a higher income, being a non-manual worker, and having completed a high level of education were significantly related to obesity requiring pharmacotherapy. More than 70% of patients with obesity requiring pharmacotherapy reported taking diet pills, eating functional foods, or consuming a one-food diet for weight reduction, but only 13.9% reported exercising for this purpose. CONCLUSIONS: Male obesity is a common condition, the prevalence of which is expected to continue to increase over time. A better strategy is required to manage male obesity in Korea.

Background: : Emergency physicians are increasingly participating in brain-death organ tissue donation (OTD).It is difficult communication to inform family members about suspected brain-death and potential donor.This study sought to explore the experiences and communication of emergency physicians in brain-death OTD. Methods: : This is a qualitative study that interviewed 10 experienced emergency physicians with brain-death OTD and analyzed the data by thematic analysis method. Results: : The study revealed 20 subthemes and 5 themes; 1) Families who are invited to donate organs make decisions after long periods of consideration by the entire family, 2) It is uncomfortable to recommend organ donation, 3) Explaining and obtaining consent is ‘the hardest job’ for the attending physician, 4) The way the attending physician does ‘the hardest job’ is by explaining, 5) Passively solicit donation. Conclusion : The experienced emergency physicians with brain-death OTD were using methods of communication to understand and sympathized with the family members and had abundant experiences. The findings of this study will help inexperienced emergency physicians with brain-death OTD.

Background: This study aimed to investigate differences in knowledge, and attitudes toward deceased organ and tissue donation of emergency physicians. Additionally, we analyzed factors affecting the attitudes toward deceased organ and tissue donation. Methods: We conducted a survey of specialists and residents registered with the Korean Society of Emergency Medicine in December 2020. The respondents’ sex, age, position, personal registration for organ donation, experience of soliciting organ donation, participation in related education, knowledge, and attitude about brain death organ donation, and attitude toward stopping life-sustaining treatments were investigated.According to the characteristics of the respondents (specialists or residents, experience and education on organ and tissue donation), their knowledge and attitude toward deceased organ donation were compared. Stepwise hierarchical multiple regression analysis was used to investigate the factors affecting the attitudes toward deceased organ and tissue donation. Results: Of the total 428 respondents, there were 292 emergency medicine specialists and 136 medical residents. Specialists and those who registered or wished to donate organs had higher knowledge and attitude scores regarding deceased organ and tissue donation.Those who had experience recommending organ and tissue donation more than 6 times had higher knowledge scores on deceased organ and tissue donation and higher overall scores in attitude. Those who received education from the Korean Organ Donation Agency had higher knowledge scores. Specialists, and those who wished to donate or had registered as organ donors and had a higher life-sustaining treatment attitude score and knowledge about deceased organ and tissue donation, had more positive attitudes toward deceased organ and tissue donation. Conclusion For more potential deceased organ and tissue donors to be referred for donation, there should be continuous education for emergency physicians on brain-dead organ and tissue donation-related knowledge and procedures. In addition, institutional or systematic improvements that can lead to organ donation when deciding on the withdrawal of life-sustaining treatment should be considered.

PURPOSE: To assess the usefulness of MRI in the preoperative diagnosis of breast implant-relatedcomplications. MATERIALS AND METHODS: Thirty four breast implants in 17 patients were examined. Eight breasts hada history of repeated surgery due to rupture and in eight others, simultaneous interstitial silicone injection hadbeen performed. MR images of the 34 implants were prospectively analyzed for implant-related complications,without prior clinical information, and the findings were compared with the results of surgery. RESULTS: Theimplant-related complications seen on MRI were infections in three cases, seromas in two, and implant malpositionin two. The linguine sign was seen in eight cases and intraparenchymal silicone in 17. Among the 32 removedimplants, rupture was genuine in ten cases (nine, extracapsular; one, intracapsular). In evaluating the MRfindings of implant rupture, the linguine sign showed 80% sensitivity, 100% specificity and 93.8% accuracy.Intraparenchymal silicon also revealed high sensitivity (90%), but relatively low specificity and accuracy (63.7%and 71.9%, respectively); this was due to the difficulty of differentiating granulomas still present after aprevious rupture from injected silicone material. MRI was useful for visualization of implant migration, thedirect relationship of extended or extruded silicone in extracapsular rupture and the localization of siliconegranulomas, as seen on multiplanar images. The extent of infection was clearly demonstrated on contrast enhancedscan. There was relatively good correlation between the degree of contracture seen on physical examination andthat seen on MRI. CONCLUSION: MRI was an effective and useful method for the preoperative evaluation ofimplant-related complications; degree of contracture was successfully predicted.
