Because recent changes in medical care security policy have made clinical skills training difficult, even in teaching hospitals, training with suitable models and simulators is becoming essential for medical students to acquire clinical skills. On the basis of these changes, we performed a nationwide survey on the prevalence and application of clinical skills laboratories for clerkships in Japan. Registered questionnaires were sent to all medical schools in Japan （n＝80） in December 2012. The response forms were filled out by clinical instructors and by the staff responsible for the skills laboratory. The response rate was 94% （75 of 80 schools）. Seventy-one schools （95%） have already installed clinical skills laboratory; however, floor area and availability varied greatly among schools. Floor space ranged from 24 to 2,250 m2 （median, 214 m2）. The number of uses of the facility by medical students in the 2011 school year ranged from less than 100 to more than 10,000 （median, 1,402）. Forty-two schools （59%） had a resident director for the skills laboratory. Simulators of most universities （> 90%） were venopuncture simulators, lung-sound simulators, basic life support mannequins, heart-sound simulators, surgical suture trainers, and automated external defibrillator trainers, and all were frequently used. These results suggest considerable differences among schools in simulation-based learning environments during clinical clerkships. Although most medical schools in Japan have their own clinical skills laboratories, their size, service, and frequency of use vary greatly.

To accurately assess the clinical competencies of medical students at Fukushima Medical University, we have developed a novel online self–assessment system, which covers all goals in the "Model Core Curriculum for Medical Education in Japan." We added "Emergency," "Communication skills with staff," and "Simulation–based learning." Following their clinical clerkships, 79 sixth–year medical students assessed themselves and their clinical clerkships.
1)This novel online self–assessment system, consisting of 68 checklists in 15 fields, easily informs us of the actual conditions of clinical clerkships and students' confidence in their clinical competencies.
2)This internet–based self–assessment system revealed the current status and problems of clinical clerkships, prompting feedback to clinical instructors and members of the instruction committee.
3)Students felt "confident" or "confident to a certain degree" in most learning areas; however, simulation–based learning seems to be necessary in several areas, such as clinical skills, where feelings of shame or discomfort may be associated with patient care.
4)Students who had high total self–assessment scores evaluated clinical clerkships favorably. In contrast, students whose self–assessments frequently included "no learning experience" evaluated their clerkships negatively in the educational aspects of "skill" and "attitude."

To investigate the effects of generational factors on the lives of medical students in the first and second years, we surveyed students about the frequency of problems and the seeking of advice.1) A questionnaire was distributed to first- and second-year students in January 2009 asking about problems regarding academic work, mental health, financial concerns, career options, physical wellness, and interpersonal relationships.2) About 70% of the students had sought advice regarding academic work and interpersonal relationships. Also, about 50% had sought advice regarding mental health.3) Students chose potential advisors depending on the type of problem; however, they preferred to consult with their classmates and upperclassmen. In addition, their parents played a role. In contrast, students rarely consulted with teachers.4) High percentages of first- and second-year medical students had various problems. Creating a support system to address these problems is important.

Background: With the expanding use of social media, medical students have been posting an increasing amount of content that against ethics and professionalism.　Objective: To develop a checklist for social media use within medical education based on our national survey.　Methods: We analyzed and classified unprofessional behaviors that occurred over the past ten years in Japan. Then, we developed an event-based checklist for the use of social media use.　Result: The behaviors violating ethics and professionalism were classified into 3 categories. We have developed a social media checklist consisting of 10 items.　Discussion: Since social networking services are becoming vital information technology, every medical student or professional may risk unprofessional behaviors when they post or exchange any professional information. We propose appropriate education using an event-based checklist for social media usage.

Introduction: To implement effective medical education, it is important to clarify the process of recognizing and comprehending medical terms.　Methods: We conducted a questionnaire survey of 492 first- to fifth-year medical students to evaluate the recognition and comprehension rates of 57 medical terms in each grade. The terms were classified using the hierarchical cluster analysis based on the recognition and comprehension rates.　Results: The response rate was 91.1% (n=448). The 57 terms were classified into the following five clusters: #1, 30 terms that the students recognized and comprehended from Y1; #2, 18 terms that the students recognized from Y1 and comprehended as the grade increased; #3, six terms that the students recognized and comprehended as the grade increased; #4, two terms that the students recognized from Y1 but had not comprehended even in upper grades; #5, one term that the students recognized as the grade increased but had not comprehended even in Y5.　Discussion: Teachers may need to devise educational strategies while considering different patterns of students’ recognition and comprehension of medical terms.

The patient was a 52-year-old woman who had undergone laparoscopic colectomy with lymph node dissection and inferior mesenteric artery preservation for cancer of the descending colon. Functional end-to-end anastomosis was performed using a linear stapler. Colonoscopy at the 1-year follow-up revealed a type 2 tumor at the anastomotic site. She was diagnosed with anastomotic recurrence. We performed laparoscopic high anterior resection with inferior mesenteric artery dissection. Rectal resection preceded mobilization of the mesocolon because of severe adhesion around the anastomotic site. Laparoscopic surgery for anastomotic site recurrence is an option under the condition that the initial surgery was laparoscopic.

A 14-year-old girl (Case 1) with respiratory distress during exercise was referred to our department after a pancreatic mass was detected by computed tomography (CT). Contrastenhanced CT scan showed a low-density mass measuring 2.5 × 2 cm in the body of the pancreas. Low signal intensity was seen on T1-weighted magnetic resonance imaging (MRI) and high signal intensity on T2-weighted MRI. We suspected solid-pseudopapillary neoplasm (SPN) of the pancreas and performed laparoscopy-assisted spleen-preserving distal pancreatectomy. The postoperative course was uneventful, and she was discharged on postoperative day 13. A 15-yearold girl (Case 2) with abdominal pain and fever was referred to our department after an abdominal cystic mass was detected by ultrasound examination. Contrast-enhanced CT showed a 4-cm well-circumscribed mass. Higher signal intensity was seen on T2-weighted MRI. We suspected SPN of the pancreas and performed laparoscopic spleen-preserving distal pancreatectomy. The postoperative course was uneventful, and she was discharged on postoperative day 8. Laparoscopic or laparoscopy-assisted surgery should be considered for SPN of the pancreas.

A 66-year-old, postmenopausal woman was referred to our hospital because of abnormal breast cancer screening results. A tumor was found in the upper outer part of the left breast. Biopsy revealed papillotubular carcinoma, ER (Allred score total score [TS] 3 = proportion score [PS] 2 + intensity score [IS] 1), PgR (Allred score TS 3 = PS 2 + IS 1), HER2 (2+), fluorescent in situ hybridization 1.1 (negative), and Ki-67 labeling index 15%. In diagnostic imaging, the tumor size was 35 mm. The diagnosis was T2N0M0 Stage IIA, luminal B-like breast cancer. First, letrozole 2.5 mg/day was administered as preoperative hormone therapy. After 2 months of treatment with letrozole, the tumor size had increased to 44 mm and preoperative hormone therapy was discontinued. She was started on preoperative chemotherapy (4 courses of epirubicin plus cyclophsphamide followed by 4 courses of triweekly docetaxel). The tumor size decreased, becoming undetectable. After these preoperative treatments, nipple-sparing mastectomy, sentinel lymph node biopsy, and breast reconstruction with a primary latissimus dorsi flap were performed. As of 3 years and 6 months after the operation, there has been no recurrence. At first, preoperative hormone therapy is performed for Luminal B-like breast cancer as in this case, if the response is insufficient, preoperative chemotherapy after hormone therapy may be a therapeutic option.

A 48-year-old woman with a history of recurrent alcoholic pancreatitis was found to have a pancreatic pseudocyst. In November 20XX, she visited the emergency department due to sudden abdominal pain. Contrast-enhanced computed tomography showed a pancreatic pseudocyst with a maximum diameter of 67 mm and ascites. A ruptured pancreatic pseudocyst was suspected and abdominal paracentesis was performed. The amylase level in the ascitic fluid was high (3444 IU/L), leading to a diagnosis of acute generalized peritonitis due to rupture of a pancreatic pseudocyst. Intraoperative findings revealed 500 mL of ascites mixed with pancreatic juice and turbid cyst contents, and distal pancreatectomy was performed. The postoperative course was favorable, and the patient was discharged on hospital day 14. Rupture of pancreatic pseudocyst is rare. In this case, it was promptly diagnosed and successfully treated with emergency surgery.
