In Japan, community–based education remains uncommon in undergraduate programs for students in schools of health sciences. The purpose of this study was to examine how students are affected by their participation in off–campus classes, which are considered as a main course of community–based education at the School of Health Sciences, Gunma University.
1)Reports submitted by students after participating in off–campus classes were broken down into sentences (with care being taken that each sentence made sense). The extracted sentences were carefully consolidated by means of the Kawakita Jiro method (affinity diagram).
2)A total of 972 sentences were extracted and were categorized into 3 categories: "enjoy going out to the community," "increased activity through experiences," "awareness of what one wants to be and one's insufficient abilities." Five middle–sized categories and 10 small categories were obtained.
3)Experiences in off–campus classes are expected to increase the activity of students and to have synergic effects with on–campus classes.
4)Community–based education might be effectively included in undergraduate programs for students in schools of health sciences.

Background & Objective: It is well established that the effectiveness of vagus nerve stimulation (VNS) therapy increases over 2-3 years. When increasing the dose of VNS, some patients were noted to respond even at low-dose stimulation in the first few months. The purpose of this study was to evaluate the relationship between an initial response to VNS and long-term response in a retrospective study of patients with intractable epilepsy. Method: We retrospectively analysed 56 patients who had VNS implantation in our centre. All patients had undergone complete presurgical evaluation. After implantation, the patients were examined at regular intervals of one month for 6-9 months and then followed up regularly for more than 2 years. Their seizure frequency and intensity were documented in their seizure logs. Results: Six patients achieved Engel class I (11%) seizure outcome, 16 achieved Engel class II (28%), and 19 achieved Engel class III (34%). Of the 22 patients with Engel I and II, the 19 in Engel class I (100%) and II (81%) showed an initial response within 6 months, an earlyonset response of VNS implantation. Conclusions: Early-onset response could be an independent predictor for achievement of Engel class I and II in long-term follow-up.

The effect of octylphthalide (OP) bathing was compared with placebo bathing on patients with rheumatoid arthritis (RA).
A liquid containing octylphthalide was dissolved in water of 40°C at a concentration of 10ppm. A liquid which has quite similar appearance and perfume to the above was used as a placebo. Double blind controlled study tests were performed.
Twenty patients (10 for OP bathing and 10 for placebo bathing) were tested by single bathing, 33 other patients (16 patients for OP bathing and 17 for placebo bathing), by serial bathing for 30 days (once a day).
After a single bathing, while grip strengths, tender joints scores, and 20m walking time improved significantly in the OP bathing group, only tender joint scores and 20m walking time improved significantly in the placebo bathing group.
After serial bathing for 30 days, tender joint scores improved significantly in the OP bathing group, but no improvement was observed in the placebo bathing group. The above results suggest that OP bathing may be beneficial for RA patients, but further study may be needed.

We studied possible factors to cause left ventricular rupture after mitral valve replacement and the prevention in eight patients of 1, 046 receiving mitral valve replacement between September, 1965 and August, 1991. The age at operation ranged from 43 to 67 years old (average 58 years old), and there were one man and seven women. According to the Treasure and Miller's classification, the type of rupture was type I in 5, type II in 2, and type III in 3. The onset time of rupture was immediately after cardiopulmonary bypass in 3 and at the time of chest closure in one. In four patients it occurred 11 hours, 14 hours, 18 hours and 25 hours after operation, respectively. In 8 patients, repair was performed with external closure under heart beating and in five patients with both internal and external closure during cardiac arrest under cardiopulmonary bypass. Two patients under cardiopulmonary bypass were successful for hemostasis, however, they died with low cardiac output syndrome, following to multiple organ failure 2 or 44 days after operation, respectively. The repair was not successful in 6 patients. In four patients the left ventricular rupture occurred immediately after hypertension and pathological findings showed severe myocardial degeneration of left ventricular muscle in all of them. These findings may suggest that hypertension after the operation is one of major factors to cause left ventricular rupture and thus the careful management of the systemic blood pressure after mitral valve replacement is effective to prevent the left ventricular rupture.

Clinical course and outcome of 34 patients with peripheral and visceral artery aneuryms, operated during 1975-1990, were analysed. There were 24 males and 10 females. Ages ranged from 14 to 87, with an average of 55 years. Peripheral aneurysms located most frequently in the lower extremity, and the incidence of various origin of the aneurysms were as follows: 14 in femoral, 5 in popliteal, 4 in internal iliac, 3 in subclavian, 2 in common iliac arteries, and 1 in each of vertebral, radial, splenic, renal and anterior tibial artery. Most common cause of aneurysm was arteriosclerosis. Multiple aneurysms were found in 59% of sclerotic type and in most of these with bilateral aneurysms in the iliac, femoral and popliteal. Ruptured aneurysms were seen in 26% of this series. Most of the aneurysms in the extremities were totally excised without difficulty, while the aneurysms in common iliac and internal iliac were opened with partial excision or obliterated with endoaneurysmorrhaphy. Arterial reconstruction was performed using saphenous vein graft or synthetic vascular graft, excepting that the internal iliac artery itself was not reconstructed. The early operative results were satisfactory, but late results showed two death and three complications of cardiovascular system. Therefore, careful follow up of the postoperative patients was recommended.
