Background: Operative blood loss during open-heart surgery has been decreasing recently. We have stopped predonated autologous blood transfusions to reduce hospital stay and cost. Material and methods: In 70 consecutive elective open-heart cases, we used intraoperative hemodilutional autologous transfusions and intraoperative autotransfusions to avoid homologous blood transfusion. Predonated autologous blood transfusion was not used. All patients received an infusion of high-dose tranexamic acid prior to and after cardiopulmonary bypass (CPB). Results: Homologous blood transfusion was not required in 77.1% of patients who underwent open-heart surgery. When further classified, 84.5% of patients who underwent primary open-heart surgery, 41.7% of patients who underwent a reoperation, and 33.3% of patients who were preoperatively anemic did not require homologous blood transfusion. In patients who undergo reoperation and who are preoperatively anemic, the rate of homologous blood transfusion is high. Therefore, during the reoperation, intraoperative autologous blood transfusion should be used before starting CPB, and iron should be given to anemic patients prior to reoperation. Conclusion: Our strategy of blood conservation consists of intraoperative hemodilutional autologous transfusion, intraoperative autotransfusion, infusion of high-dose tranexamic acid prior to and after CPB and, avoiding predonated autologous blood transfusion. Based on our experience, predonated autologous blood transfusion is usually unnecessary for cases who undergo surgery for the first time and are not anemic. Predonated autologous blood transfusion should be reserved only for high risk patients with anemia and reoperation cases. For further blood conservation, we need to study the safety limits of non-transfusion in open-heart surgery.

Introduction: In the rehabilitation period following a stroke, rehabilitation therapists must thoroughly evaluate the condition of patients for the purposes of goal-setting and effective training. Postgraduate education in the medical examination of patients after stroke was provided for rehabilitation therapists, and changes in their autonomy during medical examinations were subsequently assessed.
Method: The education consisted mainly of reading case reports about patients who had strokes and learning neurological examination techniques. A total of 35 once-weekly education sessions were provided to rehabilitation therapists working in a convalescent rehabilitation ward. The rehabilitation therapists evaluated their independence with respect to obtaining patient backgrounds, vital signs, physical findings, neurological findings, laboratory results, and basic knowledge of illness at the beginning and end of the education sessions and 6 months after the sessions ended. Each evaluation item was compared according to the time of evaluation.
Results: Rehabilitation therapists’ autonomy over obtaining patient backgrounds, neurological findings, laboratory results, and basic knowledge of illness was greater at the end of the education sessions than at the start of the sessions. Their autonomy over obtaining information in these 4 areas and obtaining physical findings was greater 6 months after the end of the education sessions than at the start of the sessions.
Discussion: We conclude that workplace postgraduate training in the medical examination of patients who have had strokes improves rehabilitation therapists’ autonomy during medical assessments.

Background. In recent years, aortic valve stenosis in the elderly is increasing. To determine the treatment of aortic stenosis in the elderly, we retrospectively evaluated the patients who underwent aortic valve replacement. Method. Between 1992 and 1997, 22 patients older than 70 years underwent aortic valve replacement for aortic stenosis. There were 15 women and 7 men, with a mean age of 73.0±4.0 years. Seven patients underwent concomitant procedures: 5 patients required coronary artery bypass grafts, 1 mitral valve plasty and 1 aortic root plasty. SJM prosthetic valves of sizes 19mm, 21mm and 23mm were used in 11, 8 and 3 patients respectively. Nobody underwent aortic annuloenlargement. Three patients underwent supraannular aortic valve replacement. All patients had New York Heart Association (NYHA) class III or IV symptoms. Results. There was no operative or hospital death. Five patients had atrial fibrillation after operation. There was only one late death, due to a traffic accident, and there was no significant complication during the follow up period. Of the 22, 21 patients improved to NYHA class I or II after operation. There were significant differences between patients who were 70 years or more and those under 70. BSA in these two groups were 1.495 and 1.615m2; p<0.01, and the amounts of blood transfusion were 918±702 and 408±428ml, p<0.01. However, there was no significant difference between these two groups in terms of ACC time (56.8 and 59.9min), CPB time (88.7 and 92.1min), ICU stay (4.0 and 3.3 days) and hospital stay (29.5 and 25.5 days). Conclusion. The results of aortic valve replacement in patients aged 70 years or more, were satisfactory. If the aortic annulus being small, a small mechanical valve prosthesis is suitable, and supraannular positioning yielded good results.

We investigated the relationship between lifestyle and cognitive function in elderly subjects who had
their checkups at a memory clinic. The 136 elderly study subjects included 51 with Alzheimer’s disease,
22 with vascular dementia, 23 with frontotemporal dementia, 25 with mild cognitive impairment, and
15 healthy control. The patients’ lifestyles were assessed using the Frenchay activities index (FAI),
and their cognitive functions were assessed by neuropsychological tests, such as the mini-mental status
examination and the frontal assessment battery (FAB). The FAI score was lower in the demented
patients than in the control subjects. Strong correlations were observed between the FAI scores and
the scores in the neuropsychological tests. The FAI scores did not correlate with the educational level
or the duration of disease. The fi ndings from the stepwise regression analysis indicated that the FAB
score, the number of family members, gender, and age were factors independently affecting the FAI
score. The results indicated that the lifestyles of the elderly people might be affected by not only their
age and family organization but also their cognitive function. We concluded that cognitive function
could play a role in the lifestyle of elderly people.

Peripheral arterial disease (PAD) is a common complication of Diabetes Mellitus (DM) and often culminates in amputation of the affected foot. Pseudomonas aeruginosa infections associated with PAD are difficult to treat due to their multi-drug resistance. Herein we report a 38 year old male who reported with DM, chronic kidney disease (CKD) and rest pain of the right second toe in October 2011. He underwent percutaneous transluminal angioplasty (PTA) which was unsuccessful. The gangrene of the toes worsened and amputation of the right second toe was done. Bacteriological examination showed presence of P. aeruginosa which during the course of antibiotic therapy became multi-drug resistant. Gangrene and abscess of the foot worsened and amputation of the right third toe was performed. Then autologous peripheral blood mononuclear cell (PBMNC) therapy was performed but as infection control could not still be achieved, the fourth toe was amputated. A protocol of foot bath using carbonic water, local usage of antibiotics (Polymyxin-B), and basic fibroblast growth factor (b-FGF) spray was then employed after which the infection could be controlled and improvement in vascularity of the right foot could be observed in angiography. This combined approach after proper validation could be considered for similar cases.

A new educational program for the medical doctor was introduced at Tokyo Women's Medical College in 1990 with a 4-year tutorial education model as its core. To develop the program for educational training more efficiently, current facilities were reviewed on a large scale, and various types of equipment and supplementary materials were made available. We are now investigating utilization and problems of the current program. Supplies and materials of tutorial rooms and mirror rooms have been used effectively. The library has become increasingly useful as a place for independent study and research. However, audiovisual materials have not yet been made fully available. We suggest that further improvements to the system and fostering an environment of open access to information are necessary to increase the accessibility of the support system for tutorial education.

Tutors must understand their role in advance so that tutorial education can be conducted smoothly and effectively. These abilities and attitudes require training. At our school, tutors serve as faculty for basic courses and clinical courses. We assessed their training conditions and future tasks. Of the 1, 077 faculty members who received tutor training between 1988 and 1997, 935 are current faculty members who have completed in-service training (basic course, 115; clinical course, 820). Before 1989, training was on campus, but since 1990 it has been conducted at Shirakawa Seminar House with a 2-day program. The number of working tutors per year is 192, with a basic course to clinical course ratio of 3: 7. About half of the faculty members in the basic course have had four or more experiences as tutors, whereas most clinical course faculty members have had only one experience. Thus, many tutors have had no experience. In a questionnaire survey after undergoing the training program, most participants felt that they were able to understand the theory of tutorial education and the actual role of the tutor and that they were able to concentrate on off-campus training that was removed from their everyday work. To provide added impetus to tutorial education, we suggest that in the future, in addition to the understanding and mutual cooperation of those involved, it will be necessary to provide an advanced program to train tutors who have appropriate abilities and attitudes.

Tokyo Women's Medical University introduced tutorial education in 1990 for 1st-through 4th-year students. To examine the effectiveness of this system in a basic-medicine course, questionnaires were given to all 2nd-year students. Many students felt that they had become accustomed to performing self-learning tasks through collecting information themselves and discussing their findings in a group; in particular, they found that tutorial education markedly improved their communication skills. A few students thought that this method helped them develop the ability of logical/critical thinking and analytic skills from multiple viewpoints. These findings suggest that an assessment system should be established by which students themselves could recognize the extent to which they have developed their abilities, which was the aim of tutorial education.

Personal interviews and group discussions were conducted with all 2nd-year students to examine how they feel about tutorial education used as the core of the basic-medicine course and how they recognize the importance of developing their abilities, which was the aim of this course. Many students showed slight anxiety about the results of their learning with tutorials, felt inadequate in their self-learning ability, and hoped the guidance by instructors would be improved. These findings suggest that students' anxiety will decreased and their willingness to learn will increase if their developed abilities are evaluated appropriately and if they receive adequate feedback. These findings also suggest that a retraining program for experienced instructors is needed to improve their guidance skills and to reinforce the importance of their role.

The frequencies of the urinary complaints oa the outpatients (male 188, female 339, average age 59.2+14.9) of the five acupuncture clinics were surveyed. The elder patients showed the higher frequencies of the urinary complaints. The frequencies of the complaints were as follows: nocturia (25.8%), urinary urgency (17.7%), stress incontinence (16.3%), sense of residual urine (15.2%), protracted micturition (12.0%), and retarded micturition (11.3%), respectively. The nocturia was accompanied with the majority of the other urinary complaints. These results suggest that the survey of the patient's complaint of nocturia is useful.
