We report a case of successfully treated mesenteric ischemia following emergency endovascular aortic repair (EVAR) for ruptured abdominal aortic aneurysm (r-AAA). A 79-year-old man, who had received hemodialysis for 5 years for diabetic nephropathy, presented with sudden onset abdominal pain. Contrast-enhanced computed tomography revealed an rAAA with a 60-mm diameter in the infrarenal abdominal aorta. Emergency EVAR was performed. After completion of stent graft placement, intraoperative angiogram revealed serious imaging delay of the superior mesenteric artery. An emergency saphenous vein bypass was performed from the right external iliac artery to the ileocolic artery. The postoperative course was uneventful, and there has been no evidence of endoleak or enlargement of aneurysm diameter during the follow-up period of 2 years.

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.

The use of axillofemoral bypass grafts (AxFG) has became a widely accepted treatment for high-risk patients with aortoiliac occlusive disease. On the other hand, AxFG has been associated with a variety of complications in the upper extremity. A symptom of upper extremity thromboembolism after AxFG occlusion is reported as axillofemoral bypass graft stump syndrome (AxFSS). We report the case of a 55-year-old man with repeated AxFSS after an AxFG occlusion. He underwent brachial artery exploration and embolectomy. Angiograms showed an embolus floating in the axillary artery, which originated from the occluded graft stump. The stump was obliterated with a metallic stent introduced through the same arteriotomy made for the embolectomy. The endovascular treatment of AxFSS is minimally invasive and is an effective modality in this condition.

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.

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."

Dialysis hypotension is one of the most common complications observed during hemodialysis. As it may be due to vasodilatation, vasoconstrictors are usually given to patients to control blood pressure. Howerver, there are some patients who are resistant to the medication with vasoconstrictors. Recently, it has been reported that as one of the treatments of dialysis hypotension, the cooling of dialysate is effective in inducing vasoconstriction via stimulating the sympathetic nerve system. Also, the application of the interaction of citrus juices with some kinds of drugs to the treatment of dialysis hypotension has been reported effective. In the present study, we examined the effectiveness of those two methods in nine hemodialysis patients in whom dialysis hypotension had not been improved with vasoconstrictors. Dialysate temperatures were lowered from 36.0 to 35.0 C during hemodialysis and/or 100m1 of citrus juice (grapefruit juice) were given to the patients before hemodialysis in addition to vasoconstrictors. Lowering dialysate temperaturse reduced the incidence of intradialytic hypotension and helped improve the patients' quality of life after hemodialysis therapy. Body temperature remained unchanged between before and after hemodialysis. However, we observed cramps in two patients and an impairment of consciousness in one patient during hemodialysis. Thus, we concluded due caution should be exercise against the side effects during hemodialysis when dialysate temperatures are lowered. Meanwhile, the intake of grapefruit juice before hemodialysis was not effective for the improvement of intradialytic hypotension and the patients' quality of life.

At Nippon Medical School, a "Basic Clinical Training Course" is provided as an introduction to clinical medicine. Medical students undergo initial clinical skills training with simulators. We describe the technique of effective training to acquire clinical skills and the results of student evaluations and a questionnaire survey.1) The training consisted of 8 practicums, including internal examination, funduscopic examination, otoscopic examination, breast examination, auscultation (heart sounds and lung sounds), and collection of blood samples. Medical students moved in rotation once per time period (45 minutes) and performed practical training in each unit, which comprised 2 practicums.2) The training with the prescribed number of 50 students in 4 time periods was efficiently performed for 2 days and required 9 trainers per day. Student evaluations and a questionnaire survey revealed the interest and enthusiasm of medical students and showed they thought highly of the training.3) The training was efficiently performed and was thought to help reduce the teaching load of instructors. The educational effect of the training can be strengthened by increasing the convenience of the clinical simulation laboratory, by reinforcing the education of clinical skills and attitudes in clinical clerkship, and by evaluating these factors after the completion of the clinical clerkship.

We have previously reported that the thoracolumbar posterior nerve root shows a tortuous epidural course, based on studies of human fetuses near term. For comparison with the cervical nerve, examinations were conducted using frontal, sagittal and horizontal sections of cervical vertebrae from 22 fetuses at 30–38 weeks of gestation. The cervical nerve root showed a short, straight and lateral course near the zygapophysial joint. Multiple rather than single bundles of the cervical posterior root seemed to account for the majority of sensory nerve fibers innervating the upper extremity. Fasciculation of rootlets was evident near the thoracolumbar spinal cord, whereas it was seen in the dural pocket at the nerve exit from the dural sac although both sites were subdural. As in the thoracolumbar region, the nerve sheath was continuous with the dura mater and independently surrounded each of the anterior and posterior roots. Radicular arteries were few in the cervical region. In 2 of the 22 fetuses (31 weeks and 33 weeks), there was a segmental, unilateral abnormality of nerve rootlet fasciculation where the dorsal root ganglion was located lateral or peripheral to the intervertebral region. Long nerve roots running inferiorly are a necessary adaptation to the delayed and marked growth of the thoracolumbar vertebral column.In children, the cervical nerve roots are likely to be affected by movement or dislocation of the vertebrae. The segmental abnormality of the cervical nerve root may be linked to rare variations in the brachial plexus.

PURPOSE: Sacroiliac fixation using iliac screws for highly unstable lumbar spine has been reported with an improved fusion rate and clinical results. On the other hand, there is a potential for clinical problems related to iliac fixation, including late sacroiliac joint arthritis and pain. MATERIALS AND METHODS: Twenty patients were evaluated. Degenerative scoliosis was diagnosed in 7 patients, failed back syndrome in 6 patients, destructive spondyloarthropathy in 4 patients, and Charcot spine in 3 patients. All patients underwent posterolateral fusion surgery incorporating lumbar, S1 and iliac screws. We evaluated the pain scores, bone union, and degeneration of sacroiliac joints by X-ray imaging and computed tomography before and 3 years after surgery. For evaluation of low back and buttock pain from sacroiliac joints 3 years after surgery, lidocaine was administered in order to examine pain relief thereafter. RESULTS: Pain scores significantly improved after surgery. All patients showed bone union at final follow-up. Degeneration of sacroiliac joints was not seen in the 20 patients 3 years after surgery. Patients showed slight low back and buttock pain 3 years after surgery. However, not all patients showed relief of the low back and buttock pain after injection of lidocaine into the sacroiliac joint, indicating that their pain did not originate from sacroiliac joints. CONCLUSION: The fusion rate and clinical results were excellent. Also, degeneration and pain from sacroiliac joints were not seen within 3 years after surgery. We recommend sacroiliac fixation using iliac screws for highly unstable lumbar spine.
