Purpose: This study determined the effects of interprofessional education (IPE) on self-efficacy and attitude by comparing an interprofessional (IP) group of medical students (MSs) and nursing students (NSs) and a uniprofessional (UP) group of MSs. Methods: An experimental IP group consisting of 49 MSs and 62 NSs was selected, alongside a UP control group of 48 other MSs. The groups participated in a class titled “Team Communication and Interprofessional Collaboration.” A sub-analysis of the two groups’ professions was also conducted. The groups participated in the same lesson separately, with a week’s interval. The Interprofessional Attitudes Scale (IPAS) and the Self-Efficacy Perception for Interprofessional Experiential Learning (SEIEL) scale were used before and after the class to compare changes in reports of self-efficacy and attitudes in both groups. Students’ responses to learning experiences and satisfaction were also evaluated. Results: IPAS and SEIEL values increased after the class for MSs in both groups; there were no differences between the groups. IPAS and SEIEL values increased after the class in MSs and NSs in the IP group, and the effect size for IPAS was larger for IP-group NSs than for IP-group MSs. Satisfaction scores exceeded 3.70 in both groups. Conclusion The UP group showed similar IPE effects as the IP group, as measured by SEIEL and IPAS, in a single IPE program that used role-play and case-based discussion. However, it would be desirable for the UP group to interact with other professions to improve understanding and experience.

A collodion baby is born with a tough, inelastic parchment-like membrane covering the whole body surface. As the meinbrane fissures and peels, a more characteristic ichthyosiform change is evident beneath the collodion membrane. Uncommonly, normal skin is found under it. We herein present two cases af collodion baby, which were confirmed as a sporadic case of lamellar ichthyosis and a case of lamellar exfoliation of the newborn, respectively, after long-term clinical observation. It is necessary that detailed genetical and molecular biological studies should be perforrned in order to elucidate the fur:damental, molecular changes that cause these dramatic cutaneous changes.

Interprofessional education (IPE) fosters knowledge, skills, and attitudes related to interprofessional collaboration (IPC) for safe, quality patient care. In recent years, the importance of IPC has extended beyond the medical field to local community settings. However, IPE has only recently been introduced and has yet to become widespread. This study reviews the origin and development of IPE in Korean medical education by comparing it with established models in other countries that provide useful insights into future directions for IPE in Korea. Dedicated institutions led the IPE effort in other countries; however, IPE initiatives in Korea were mainly driven by individual professors’ and medical schools’ interest and commitment, without structural support systems. An important finding of this study is that the lack of awareness and organizational support within the medical education community resulted in the absence of a mandatory curriculum for IPE, as it was omitted from the accreditation standards. For more organized adoption and implementation of IPE in Korea, this study suggests the need to widely communicate the importance of IPE to the medical community and the public. It is also imperative to establish leadership capable of guiding IPE, share materials through trusted institutions with IPE experience, and include IPE in the accreditation standards. These steps are essential for actively implementing IPE and meeting societal healthcare needs in Korea.

PURPOSE: To assess the accuracy of MR cholangiography(MRC) in the diagnosis of cholelithiasis, and to determine interobserver agreement. MATERIALS AND METHODS: Between March and September 1999, 43 consecutive patients with biliary obstruction [24 men and 19 women aged 25 -85 (mean, 58) years] underwent MRC using the single-shot fast spin-echo technique. Heavily T2-weighted source images(axial and coronal) 3 -5 mm thick and 12 projection images with 15- degree rotation and 5-cm thickness were obtained. All images were reviewed blindly and indepen-dently by two radiologists specialized in the interpretation of abdominal imaging information. Choledocholithiasis was evaluated in eight segments of the intrahepatic duct(IHD), extrahepatic duct(EHD) and gall bladder lumen. Final diagnosis was established on the basis of operative (n=31) and other radiological (n=12) findings. The sensitivity, specificity and accuracy of the MRC findings were assessed, and using kappa measurement (cross-table analysis,SPSS Windows for 8.0), interobserver agreement was determined. RESULTS: Thirty of the 43 patients, had choledocholithiasis (IHD stones in 7 cases, EHD stones in 15, and GB stones in 18). For radiologist 1, sensitivity, specificity and accuracy were 86%, 100% and 98%, respectively, in the diagnosis of IHD stones; 100%, 89% and 93%, respectively, in the diagnosis of EHD stones; and 81%, 96% and 91%, respectively, in the diagnosis of GB stones. For radiologist 2, the corresponding figures were 86%, 94% and 93% (1HD stones); 87%, 89% and 88% (EHD stones); and 81%, 86% and 84% (GB stones). Interobserver agreement for the diagnosis of choledocholithiasis was excellent in all cases. The kappa mesurement was 0.91 for 1HD stones, 0.77 for EHD stones, and 0.70 for GB stones. CONCLUSION: MRC is an excellent imaging modality for the diagnosis of choledocholithiasis, and interobserver agreement was also excellent.

The population aged 95 years and older in Seoul approximately increased to five-fold over the past 10 years, while nationwide rates increased to three-fold. In order to examine the dietary habit and nutritional status of oldest-old population living in Seoul, we recruited 87 subjects (25 males and 62 females) aged 95 years and older. The prevalence of underweight (BMI < 18.5 kg/m2) and obesity (BMI > or = 25 kg/m2) were 18.2% and 18.2% in males, and 20.8% and 9.4% in females, respectively. In self-assessment of health, only 25.3% answered to be unhealthy. More males exercised regularly and reported a wide range of activities than females. The average of %Kcal from carbohydrate, protein and fat (C : P : F) was 64.9 : 13.8 : 21.2 in males and 68.1 : 14.2 : 17.7 in females. The average daily energy intake was 1,307 kcal in males and 1,304 kcal in females. More than 75% of subjects were taking under estimated average requirements (EAR) for vitamin B1, B2 & C and Ca. The average of mean adequacy ratio (MAR) was 0.66 in males and 0.70 in females, and 28.8% of males and 12.9% of females were in MAR < 0.50. Based on MAR, 32.0% of males and 14.5% females were classified as normal and 16.0% of males and 25.8% of females were classified as malnourished. Our subjects were taking more animal food, especially milk and its products, compared to those living, in rural areas. However, a significant proportion did not meet the EAR for vitamin B1, B2 & C and Ca.

Purpose: This study aimed to develop a mobile-based self-management health alarm (MSHA) program for modifying obese children's lifestyle based on the information-motivation-behavioral skills (IMB) model and to test its feasibility. Methods: A methodological study for the development of the MSHA program and pilot study with a one-group pretest-posttest design for feasibility testing was conducted. The MSHA program was designed to provide obesity-related information (I), monitor daily diet and exercise, provide motivational text messages (M), and enhance healthy diet and exercise skills (B) via a mobile-based web platform. In the feasibility test, six obese children participated in the 4-week program, and the number of days per week that they achieved their goals and differences in metabolic components were assessed. Data were analyzed using descriptive statistics and the Wilcoxon signed-rank test. Results: Participants successfully achieved their diet and exercise goals≥5 days per week. Body mass index (z=-1.99, p=.046), waist circumference (z=-2.20, p=.028), and triglyceride levels (z=-2.21, p=.027) significantly decreased. Conclusion The MSHA program showed positive effects on health behaviors and metabolic syndrome risk. The program may be effective in improving metabolic syndrome in obese children by promoting self-health management behaviors.

This study aimed to analyze the subjects, situations, and reflection levels related to role modeling experienced by medical students during their clinical clerkship and their own reflections. This study intends to suggest ways of improving how residents and clinical faculty should treat and teach medical students. Written interviews were conducted regarding senior medical students’ role modeling experiences during their clinical clerkships in 2018 and 2019. Content analysis was conducted for a total of 224 cases from 196 students. Content analysis revealed three types of role modeling content: subjects (faculty, residents, nurses, peer students), situations (clinical competence, personal qualities, teaching skills), and the level of reflection (critical reflection, reflection, thoughtful action, and habitual action) in each case. As role model subjects, faculty were found to be the paramount role model (n=142, 62.83%). Role modeling was the most frequently performed for clinical competence (n=103, 45.98%). Clinical competence was frequently shown in communication and empathic listening during rounds and outpatient relationships between the patient and doctor. Regarding the level of reflection for role modeling, the number of critical reflections was 86 (38.39%) and that of reflections was 80 (35.71%). In particular, negative role modeling showed a high level of critical reflection in relation to faculty (64.44%) and nurses (8.89%). In conclusion, role modeling of medical students participating in clinical clerkships occurs in situations that the role models are not aware of, with positive or negative effects on the formation of professional identity among medical students.

BACKGROUND: To determine the natural progression of conservatively treated rotator cuff tears, we evaluated changes in radiologic and clinical parameters in patients whose recalcitrant tears were neglected after conservative treatment. METHODS: A total of 73 patients with recalcitrant rotator cuff tears in spite of conservative treatment were included in this study. We measured changes in tear size and in the extent of fatty infiltration of the rotator cuff by comparing the initial and final follow-up magnetic resonance imagings (MRIs). To determine factors influencing the change in tear size, we collected the medical history of patients taken at the time of initial admission. RESULTS: The average follow-up period was 20.1 months, and the average increase in tear size across this period was 6.2 mm. In terms of steroid injection, we found that the increases in tear size of the steroid injection group (p=0.049) and of the sub-group that had received more than three steroid injections (p=0.010) were significantly greater than that of the non-steroid injection group. CONCLUSIONS: We found that the increase in cuff tear size was on average 6.2 mm across the follow-up period, indicating that neglecting cuff tears may cause them to progress into more severe tears. We also observed that a history of steroid injection might be a possible risk factor for a worse prognosis of cuff tears. Therefore, we suggest that patients with rotator cuff tears and a history of steroid injection are recommended aggressive modes of treatment such as surgery.

The objective of this study was to evaluate the relationship between beta-galactosidase activity in urine, in serum and urinary N-acetyl-beta-glucosarminidase activity as an early indicator of renal effect and mercurT concentration in urine and blood, reflecting the intensity of exposure to or the amount of body burden of mercury. This study was carried out among 70 workers exposed to mercury vapor and 63 non-exposed workers as a reference. The results were as follows ; 1. The mean concentration of urinary mercury (43.5 microgram/1) in exposed subjects was about nine times higher than that of non-exposed subjects, but the mean values of blood mercury were not different from each other 2. The mean values of beta-galactosidase activity in urine (119.7micromoleMU/h/g creatinine) and in blood (73.7 moIMU/H/l) of mercury-exposed subjects were significantly higher than those of non-exposed subjects. 3. In mercury-exposed subjects, beta-galactosidase activities in urine (r=0.38, p<0.01) and in serum (r=0.26, p<0.05) were correlated to urinary mercury concentration, but not to blood mercury concentration. The urinary excretion of beta-galactosidase activity was closely associated with urinary mercury concentration in the result of the multiple regression analysis. 4. The urinary beta-galactosidase activity in exposed subjects increased as the urinary mercury increased, and in the exposed subjects with more than 50microgram/1 of urinary mercury was highly related to urinary beta-galactosidase activity(r=0.47, p<0.05). 5. Among exposed subjects with more than 50microgram/l of urinary mercury, 20.0% of them showed abnormal value of urinary beta-galactosidase activity.
