Intracranial lipoma is a rare tumor. It is considered as congenital malformation, caused by poor differentiation and abnormal persistence of the primitive meninges. More frequently intracranial lipomas are central and located in the midline especially in corpus callosum. We report the two cases of intracranial lipoma, one case was detected in cerebellum by antenatal sonography and the other one was detected in right temporal cistern by cranial sonography during the postnatal follow-up.

PURPOSE:This study was designed to know the clinical significance and risk factors of hyperkalemia in very low birth weight infants (VLBWI). METHODS:We compared the incidence of hyperkalemia and its associated ECG abnormalities and mortality rate according to birth weight (102 of less than 1,000 g vs. 328 of 1,000 to 1,500 g) in 430 VLBWI who were born from Jan. 2000 to July 2004, retrospectively, and also compared the several parameter according to serum potassium (35 of hyperkalemia vs. 11 of normokalemia) in 49 selected VLBWI who need mechanical ventilation for respiratory distress without oliguria within 72 hours of life to know the risk factors of hyperkalemia. RESULTS:Overall incidence of hyperkalemia in VLBWI was 21.1%, and was significantly higher in below 1,000 g than in 1,000 to 1,500 g (32.4% vs. 17.7%, P<0.05). Hyperkalemia associated ECG abnormalities, life-threatening cardiac arrhythmia, and death were also significantly higher in below 1,000 g. There were no significant differences in maternal or infant's characteristics, laboratory findings and clinical conditions between hyperkalemic vs. normokalemic group. The incidence of cardiac arrhythmia and mortality rate were also significantly higher in hyperkalemic group. CONCLUSION:Early onset nonoliguric hyperkalemia is often associated with life- threatening cardiac arrhythmia and death in VLBWI, especially less than 1,000 g. Although perinatal risk factors were not found in this study, prospective study is needed to establish the preventive strategy and to improve the outcome.

BACKGROUND: To establish effective preventive measures for hepatitis A virus (HAV) infection, a nationwide epidemiologic study on seroprevalence of anti-HAV and the disease prevalence is needed. The aim of this study was to analyze the recent sero-epidemiological changes of hepatitis A markers in Korea. METHODS: The results of 11,068 anti-HAV total and 32,360 anti-HAV IgM tests by electro-chemiluminescence immunoassay (ECLIA) that had been requested in recent four years (2005-2008) to a reference medical laboratory from 1,699 institutions nationwide were retrospectively analyzed according to the distribution of year, sex, and age groups. RESULTS: The overall positive rate of anti-HAV total was 62.8%. The overall positive rate of anti-HAV IgM was 11.0%, showing a significantly increasing trend by year: 7.7%, 10.9%, 8.9%, and 14.3% in 2005, 2006, 2007, and 2008, respectively (P<0.0001). The positive rate of anti-HAV IgM was higher in male than in female subjects (11.8% vs 10.0%, P<0.0001), and 81.8% (2,916/3,566) of the anti-HAV IgM positive results were observed in the age groups of 21-40 yr. The annual positive rates of anti-HAV total and anti-HAV IgM showed significantly decreasing and increasing trends, respectively, in the age groups of > or =21 yr. Conclusion: In accordance with a decreasing sero-positivity of anti-HAV total, the prevalence of acute hepatitis A virus infection has been considerably increased during the recent four years in the age groups of > or =21 yr. The results of this study could be used effectively as a basic data for establishing effective preventive measures for hepatitis A including vaccination in these susceptible age groups.

BACKGROUND: There are limited data regarding smoking cessation treatment by physicians in Korea. Thus, we investigated the attitude to smoking cessation intervention and services among Korean physicians. METHODS: This survey was conducted in 987 participating physicians who had experiences in smoking cessation services. The subjective difficulties of smoking cessation services and its causes and the presumptive reasons for failure of smoking cessation among their patients were investigated using questionnaires. RESULTS: Overall smoking rate among Korean physicians who participated in this survey was 12.6%. Most participating physicians had a difficulty in smoking cessation services and its causes were high cost of medication for smoking cessation due to non-imbursement (50.7%) and the absence of a medical fee on smoking cessation services (34.8%). The high cost of medication for smoking cessation due to non-imbursement (29.5%) also ranked high in the presumptive reasons for failure of smoking cessation among their patients. CONCLUSION: The smoking rate of Korean physicians in this survey was lower than those of the general population. Most participating physicians had a difficulty in offering smoking cessation services. And the most common cause for the difficult was non-imbursement of their services and medication.

This study was conducted to estimate the socioeconomic costs of overweight and obesity in a sample of Korean adults aged 20 yr and older in 2005. The socioeconomic costs of overweight and obesity include direct costs (inpatient care, outpatient care and medication) and indirect costs (loss of productivity due to premature deaths and inpatient care, time costs, traffic costs and nursing fees). Hypertension, diabetes mellitus, dyslipidemia, ischemic heart disease, stroke, colon cancer and osteoarthritis were selected as obesity-related diseases. The population attributable fraction (PAF) of obesity was calculated from national representative data of Korea such as the National Health Insurance Corporation (NHIC) cohort data and the 2005 Korea National Health and Nutrition Examination Survey (KNHANES) data. Direct costs of overweight and obesity were estimated at approximately U$1,081 million equivalent (men: U$497 million, women: U$584 million) and indirect costs were estimated at approximately U$706 million (men: U$527 million, women: U$178 million). The estimated total socioeconomic costs of overweight and obesity were approximately U$1,787 million (men: U$1,081 million, women: U$706 million). These total costs represented about 0.22% of the gross domestic product (GDP) and 3.7% of the national health care expenditures in 2005. We found the socioeconomic costs of overweight and obesity in Korean adults aged 20 yr and older are substantial. In order to control the socioeconomic burden attributable to overweight and obesity, effective national strategies for prevention and management of obesity should be established and implemented.

Myalgia, muscle weakness, muscle cramping, muscular rigidity and elevated levels of serum creatinine kinase (CK) are very common in patients with hypothyroidism. However, these symptoms are not clinically serious in most cases and are not found in primary care. So far, 5 Cases with hypothyroid myopathy have been reported in the Korean literature. However, it is not reported that this case has been found in primary care or in periodic health examination. We report a case of hypothyroid myopathy that was presented with exercise-induced myalgia. This case was diagnosed as hypothyroid myopathy through abnormal thyroid function test and elevated levels of serum CK and myoglobin in periodic health examination. Muscle symptoms and laboratory abnormality were improved only with thyroid hormone replacement therapy.

OBJECTIVES: This study was conducted to estimate medical expenditure attributable to overweight and obesity in adults with hypertension, diabetes and dyslipidemia using Korea National Health and Nutrition Examination survey data and Korea National Health Corporation data. METHODS: The medical expenditure of hypertension, diabetes and dyslipidemia related to overweight and obesity were composed of inpatient care costs, outpatient care costs and medication costs. The population attributable risk (PAR) of overweight and obesity was calculated from national representative data of Korea such as the National Health Insurance Corporation cohort data and 2005 Korea National Health and Nutrition Examination survey data. RESULTS: The medical expenditure attributable to overweight and obesity of hypertension were 456 billion won (men : 215 billion won, women : 241 billion won). Those of diabetes were 282 billion won (men : 148 billion won, women : 135 billion won), and of dyslipidemia were 17 billion won (men : 9 billion won, women : 8 billion won). Consequently, these costs corresponded to 33.3% of total medical expenditure due to hypertension, diabetes and dyslipidemia. CONCLUSIONS: We found a substantial medical expenditure due to overweight and obesity of hypertension, diabetes and dyslipidemia were very high. In order to reduce these costs, effective national strategies for prevention and management of overweight and obesity should be established and implemented.

Purpose: This study aimed to investigate the difference in satisfaction and learning benefits between e-portfolios compared to paper portfolios during clinical practice in medical schools. Methods: Utilization of and satisfaction with e-portfolios among 40 third-year medical students in the medicine department of Ajou University School of Medicine was collected using an online survey in December 2020. The collected data were analyzed using descriptive statistics and an analysis of variance. Results: Students perceived that e-portfolios were highly beneficial for consistently documenting activities during clinical practice, when compared to paper-based portfolios (mean±standard deviation [SD]=2.60±1.22). However, the least rated aspect was that e-portfolios require less time than paper-based portfolios (mean±SD=1.80±1.14). Additionally, among the various clinical practice courses using e-portfolios, the highest satisfaction was observed with the fewest content items in the e-portfolio. Conclusion To maximize the potential benefits of e-portfolios, improvements in implementation and usability are essential. Additionally, for effective utilization of e-portfolios in clinical practice, it is necessary to clearly define students’ required competencies and ultimate goals, and structure content accordingly.
