ABSTRACT

The general practitioner (GP) system in Britain was developed about 40 years ago within the National Health Service (NHS) system. Currently 99% of people are registered to GPs from whom they receive primary care and, if necessary, are referred to specialists working in hospitals. Thus, there is a marked difference between the health care systems of Japan and Britain. However, the GP educational system in Britain is very helpful in increasing the number of doctors practicing primary care. The following are proposed in order to reform the pre-and postgraduate medical education system in Japan. 1. An integrated curriculum including the subject of community practice should be introduced early in the undergraduate years. 2. A compulsory, broad clinical training system that includes community practice should be introduced in the early postgraduate period. 3. The international experience of clinical trainees should be increased in order to catch up with changes in the health care in other parts of the world.

ABSTRACT

Objective.-To survey a broad sample of Japanese internists regarding the effects of postgraduate training on their ability to provide ambulatory care.<BR>Design.-Analysis of internists trained at university or non-university hospitals (as designated by the Ministry of Health and Welfare) by written questionnaire.<BR>Results.-74.0% of respondents (127 in total) had undergone ambulatory care training. 30.7% were trained in outpatient clinic sessions that were held more than once a week on average. 85.8% of respondents said they recognized the differences between ambulatory care and inpatietn care. Furthermore, the percentage of respondents who understood such differences during their postgraduate training periods was higher in the group that had had ambulatory care training than the group that had not. Many respondents also suggested the necessity of training in non-internal medicine specialties (e. g. dermatology, OB-GYN, otolaryngology, orthopedics, urology and ophthalmology) that were not popular postgraduate training programs.<BR>Conclusion.-Postgraduate training had a large effect on the ability of internists to provide ambulatory care. Japanese postgraduate training is still not sufficient in this regard. Residency training programs should put more emphasis on ambulatory care.

ABSTRACT

Our previous study concerning evaluation methods of postgraduate clinical training showed a usefulness in improving clinical training, especially in the fields of clinical skills and knowledge. However, it also pointed out the unsolved problem of assessment of those behaviors in which no significant differences were shown throughout the residency period. In order to solve this problem, a feedback system has been introduced, consisting of self-evaluation during the residensy, and appropriate counseling regarding hortcomings.<BR>In the present study, the effect of this feedback system on clinical training, particularly on physician behavior, has been analyzed. The study was performed by comparing evaluation scores, based on a five-point scale, from two groups: 35 residents who did not undergo the feedback system, and 84 residents who had. Clinical skills, knowledge, positiveness, behavior with patients and colleagues, and patients' records, were each evaluated after discussions by the teaching staff.<BR>Our results showed that there was a significant improvement not only in clinical skills and knowledge, but also in physician behavior in the group using the feedback system. Thus, it appears that this feedback system is useful in improving postgraduate clinical training.

ABSTRACT

Causative factors for thrombi formation in left atria of 38 patients with mitral stenosis who underwent mitral valve surgery (open mitral commissurotomy or mitral valve replacement) alone or in combination with other procedures were studied. There were 9 cases of left atrial thrombosis (LAT). Left atrial diameter was increased in LAT(+) group (6.1±1.6cm) compared with LAT(-) group (4.6±0.7cm). There was significant difference in the left atrial diameter between the two groups of patients (<i>p</i><0.01). Cardiac output was decreased in LAT(+) group (3.04±0.74<i>l</i>/min) compared with LAT(-) group (3.99±1.07<i>l</i>/min). Cardiac output of LAT (-) group was significantly larger than that of LAT(+) group (<i>p</i><0.05). Mean transition time of blood through left atrium (MTT<sub>LA</sub>) was calculated using left atrial volume and cardiac output. In LAT (+) group, MTT<sub>LA</sub> was significantly increased (6.2±3.9sec) compared with LAT(-) group (2.9±1.6sec). It is considered that, in mitral stenosis, prolongation of MTT<sub>LA</sub> is one of the risk factors for thrombi formation in the left atrium.

ABSTRACT

A thirteen-day-old neonate was admitted because of systolic heart murmur, tachycardia, tachypnea and sucking weakness. The chest X-ray film demonstrated remarkable cardiomegaly and pulmonary congestion. Echocardiography detected marked thickening and stenosis of the aortic valve, and left ventricular dysfunction (EF=10%). The pressure gradient between left ventricle and ascending aorta was presumed 130mmHg with pulsed Doppler echocardiography, Since he did not respond to conservative treatment, an emergency open aortic valvular commissurotomy under cardiopulmonary bypass was performed the day after admission. We made incisions of 1mm in the left side and 0.5mm in the right side commissure of the adherent bicuspid aortic valve. After the procedure, left ventricular function improved (EF=57%), and the pressure gradient was reduced to 62mmHg. He showed good recover from the congestive heart failure. There are few reports about operative treatment of congenital aortic valve stenosis in neonates. This is considered to be the third youngest successful operative case of open aortic valvular commissurotomy in Japan.

ABSTRACT

Prostaglandin E<sub>1</sub> (PGE<sub>1</sub>) was used continuously in adults from immediately after induction of anesthesia, during extracorporeal circulation, to the acute phase after open heart surgery. Using blood flow in the toe determined by laser Doppler flowmeter and the temperature difference between periphery and core as indices, the effects of afterload reduction and improvement of peripheral circulation were investigated. Subjects were 17 adults who underwent open heart surgery. PGE<sub>1</sub> was used in 7 patients and not used in 10. In the group using PGE<sub>1</sub>, continuous injection of 0.015μg/kg/min of PGE<sub>1</sub> was started immediately after induction of anesthesia and was maintained during extracorporeal circulation until the acute phase after surgery. During extracorporeal circulation, perfusion pressure was kept at 50∼60mmHg and PGE<sub>1</sub> injection was controlled within the range of 0.015∼0.030μg/kg/min. At completion of extracorporeal circulation, the dose was fixed at 0.015μg/kg/min again. The degree of improvement of peripheral circulation was evaluated on the basis of hemodynamics, blood flow in the toe determined by laser Doppler flowmeter and the temperature difference between periphery and core, at induction of anesthesia (before using PGE<sub>1</sub>) on completion of extracorporeal circulation, and in the acute phase after surgery. The value of blood flow in the toe determined by laser Doppler flowmeter was significantly higher in the PGE<sub>1</sub> group than in the non-PGE<sub>1</sub> group, from completion of extracorporeal circulation to the acute phase after surgery. Moreover, peripheral temperature was significantly higher in the PGE<sub>1</sub> group than in the non-PGE<sub>1</sub> group at completion of the extracorporeal circulation as well as immediately after surgery, and the temperature difference between periphery and core was significantly smaller. Continuous injection of PGE<sub>1</sub> enabled smooth control of perfusion pressure during extracorporeal circulation. Although there was no significant difference in peripheral vascular and total pulmonary resistance, the coefficients tended to be lower in the PGE<sub>1</sub> group. The use of PGE<sub>1</sub> during open heart surgery seems to be an effective method to improve peripheral circulation.

ABSTRACT

Fifty-five adult patients with atrial septal defect (ASD) were surgically treated. In the preoperative study, 6 patients showed high pulmonary artery systolic pressure (>50mmHg). However, there was no linear relation between PAP and age, nor between <i>Q</i><sub>p</sub>/<i>Q</i><sub>s</sub> and PAP. As for the additional surgical procedures, MVR (1), MAP (1), TAP (3), OPC (2) were carried out with ASD closure in 7 patients. Post-operative evaluation with echocardiography revealed increase in the left ventricular chamber size, decrease in the severity of tricuspid regurgitation and same grade mitral regurgitation compaired with pre-operative level. From these data, the prediction of the atrioventricular valve regurgitation after ASD closure seemed to be difficult just from the preoperative evaluation, Transesophageal echocardiography was useful for the evaluation of residual atrioventricular valve regurgitation during operation in the cases of ASD with over II grade regurgitation preoperatively.
