ObjectivesTo examine the relationship between stress, social support, and empathy among medical students.MethodsWe evaluated the relationships between stress and empathy, and social support and empathy among medical students. The respondents completed a question-naire including demographic information, the Jefferson Scale of Empathy, the Perceived Stress Scale, and the Multidimensional Scale of Perceived Social Support. Corre-lation and linear regression analyses were conducted, along with sub-analyses according to gender, admission system, and study year.ResultsIn total, 2,692 questionnaires were analysed. Empathy and social support positively correlated, and empathy and stress negatively correlated. Similar correla-tion patterns were detected in the sub-analyses; the correla-tion between empathy and stress among female students was negligible. In the regression model, stress and social support predicted empathy among all the samples. In the sub-analysis, stress was not a significant predictor among female and first-year students.ConclusionsStress and social support were significant predictors of empathy among all the students. Medical educators should provide means to foster resilience against stress or stress alleviation, and to ameliorate social support, so as to increase or maintain empathy in the long term. Furthermore, stress management should be emphasised, particularly among female and first-year students.

BackgroundMedical education must adapt to different health care contexts, including digitalized health care systems and a digital generation of students in a hyper-connected world. The aims of this study are to identify and synthesize the values that medical educators need to implement in the curricula and to introduce representative educational programs.MethodsAn integrative review was conducted to combine data from various research designs. We searched for articles on PubMed, Scopus, Web of Science, and EBSCO ERIC between 2011 and 2017. Key search terms were “undergraduate medical education,” “future,” “twenty-first century,” “millennium,” “curriculum,” “teaching,” “learning,” and “assessment.” We screened and extracted them according to inclusion and exclusion criteria from titles and abstracts. All authors read the full texts and discussed them to reach a consensus about the themes and subthemes. Data appraisal was performed using a modified Hawker ‘s evaluation form.ResultsAmong the 7616 abstracts initially identified, 28 full-text articles were selected to reflect medical education trends and suggest suitable educational programs. The integrative themes and subthemes of future medical education are as follows: 1) a humanistic approach to patient safety that involves encouraging humanistic doctors and facilitating collaboration; 2) early experience and longitudinal integration by early exposure to patient-oriented integration and longitudinal integrated clerkships; 3) going beyond hospitals toward society by responding to changing community needs and showing respect for diversity; and 4) student-driven learning with advanced technology through active learning with individualization, social interaction, and resource accessibility.ConclusionsThis review integrated the trends in undergraduate medical education in readiness for the anticipated changes in medical environments. The detailed programs introduced in this study could be useful for medical educators in the development of curricula. Further research is required to integrate the educational trends into graduate and continuing medical education, and to investigate the status or effects of innovative educational programs in each medical school or environment.

The clinicopathologic features of the intraductal growth (IG) type of peripheral cholangiocarcinoma (PCC) were examined retrospectively. Out of 112 patients who underwent surgery for PCC at Seoul National University Hospital, Seoul, Korea, between January 1980 and December 1997, 16 were classified as having the IG type. Thirteen were men and 3 were women. Their ages ranged from 38 to 73 years with a mean age of 55.9 years. Abdominal pain was the most common symptom and jaundice was found in 18.8%. Five patients had associated clonorchiasis and 6 patients experienced hepatolithiasis. Tumor sizes ranged from 0.5 cm to 14.0 cm with a mean of 4.3 cm. The tumor was located in the right lobe in 7 cases and the left lobe in 9 cases. Thirteen patients underwent major hepatic resection, and 3 underwent minor resection, involving a subsegmentectomy. Mucin was found in the bile in 4 cases. Pathology showed papillary adenocarcinoma with a background of adenomatous hyperplasia, and the absence of lymph node metastasis in all cases. The tumors were confined to the mucosa in 5 cases. Out of the 16 hepatic resections, 1 was palliative due to a positive margin. In 2 of the patients who underwent minor resections, recurrences developed, and 1 of these died 56 months after resection. Out of the 16 patients, 15 remain alive, ranging from 1 to 13 years, postoperatively. In conclusion, the IG type of PCC should be distinguished from other types of PCC because a favorable prognosis can be expected after complete surgical resection. (HEPATOLOGY 2000;31:12-17.)Intrahepatic or peripheral cholangiocarcinoma (PCC), a primary adenocarcinoma of the liver originating from the intrahepatic bile ducts (IHD), is the second most common primary hepatic malignancy, next to hepatocellular carcinoma. 1 Because the lesion is advanced by the time of diagnosis, 2 the possibility of surgical resection is limited and the prognosis is generally poor. [3][4][5][6][7][8][9] In 1992, Yamamoto et al. 10 classified PCC into 2 types, mass-forming (MF) and periductal-infiltrating (PI), and showed their different clinical behaviors. The MF type creates an apparent lesion in the liver, with frequent remnant hepatic recurrence after resection. The PI type causes a stricture or an obstruction of the IHD without forming a definite mass in the liver. It spreads along the Glisson' s capsule and metastasizes to the hilar lymph nodes. Later, another type, intraductal growth (IG), was added. 11 This type of tumor shows a papillary growth into the lumen of the bile duct. 12 There have been a few scattered reports about the clinical and pathological features of the IG type of PCC. 13,14 Here, we describe the clinical and pathological features of the IG type of PCC in 16 patients who underwent surgical resection at

The JSE score of Korean medical students was lower than that of students in Western countries. The difference of gender and medical school admission system should be considered, and capability to apply empathy to clinical practice should be focused upon in medical training.

PurposeThe laparoscopic appendectomy has been a basic part of the principal of a more complex laparoscopic technique for the surgical trainee. As the number of laparoscopic appendectomies performed by surgical trainees has increased, we are trying to check the stability of, which is controversial, and the learning curve associated with a laparoscopic appendectomy.MethodsWe studied the demographics, histologic diagnoses, operative time, the number of complicated cases, and hospital duration of one hundred and three patients who underwent an open appendectomy (group A, 53) or a laparoscopic appendectomy (group B, 50) retrospectively through a review of their medical records. The learning curve for the laparoscopic appendectomy was established through the moving average and ANOVA methods.ResultsThere were no differences in the operative times (A, 64.15 ± 29.88 minutes; B, 58.2 ± 20.72 minutes; P-value, 0.225) and complications (A, 11%; B, 6%; P-value, 0.34) between group A and group B. Group B was divided into group C who underwent the operation in the early period (before the learning curve) and group D who underwent the operation in the later period (after the learning curve). The average operative time for group C was 66.83 ± 21.55 minutes, but it was 45.25 ± 10.19 minutes for group D (P-value < 0.0001). Although this difference was statistically significant, no significant difference in the complication rate was observed between the two groups.ConclusionA laparoscopic appendectomy, compared with an open appendectomy, performed by a surgical trainee is safe. In this study, the learning curve for a laparoscopic appendectomy was thirty cases.

Patient safety education effectively shifted students' attitudes towards systems-based thinking and increased their sense of collective responsibility. Strategies for improving superior-subordinate communication within a hierarchical culture should be added to the patient safety curriculum.

The role of hepatic resection for metastatic gastric cancer is less well defined due to the tendency of gastric cancer to widely metastasize. The purpose of this study is to examine the beneficial effect of hepatic resection in patients with metastatic gastric cancer. The clinicopathologic features and long-term results of 11 patients who underwent hepatic resection for metastatic gastric cancer from January 1988 to December 1996 at Seoul National University Hospital were analyzed retrospectively. All resected hepatic metastases were solitary lesions. Among eight patients with synchronous hepatic metastases, one patient with early gastric cancer and lymph node metastases (T1N2M1) remained alive for 8 years 6 months after hepatic resection without recurrence. Among three patients with metachronous hepatic metastases, two patients with advanced gastric cancer and lymph node metastases (T3N2M0, T2N1M0 at the initial operation, respectively) survived 8 years 6 months and 3 years after hepatic resection, respectively. Median survival times of synchronous and metachronous hepatic metastases were 13.0 and 74.3 months, respectively. In solitary hepatic metastatic lesions from gastric cancer, surgical resection should be considered as one of the treatment options.
