1) Although maternity leave can facilitate the professional success of female students.The extent to which maternity leave is implemented remains unknown.A cross-sectional questionnaire survey of all Japanese medical schools and postgraduate schools in medicine (N=81) was performed.Responses were received from 55 medical schools and postgraduate medical schools (response rate=67.9%).The results showed that no school had formally established a maternity leave policy for students.
2) We found that medical educators had reorganized clinical clerkship programs to accommodate the pregnancies of students but expressed confusion about how to manage such situations.
3) We also found that many female postgraduate students drop out because of pregnancy or child-care responsibilities. Medical schools and postgraduate schools should recognize the importance of maternity leave and should not close their doors to pregnant students who are contending with both motherhood and academic achievement.

Gait disturbance is a serious problem in Parkinson's disease (PD). Exercise therapy is used to alleviate this complaint. We investigated the effects of a videotaped arm swinging-based home exercise program on gait in PD patients. The subjects included 25 outpatients aged between 55 and 77 years (average age 68.9 years) with PD in Hoehn and Yahr stages II-IV. We prepared a master video tape in which a trainer was shown to be performing an arm swinging exercise or steps in synchrony with a metronome. The exercise menu consisted of 4 parts : arm swinging in a seated position, arm swinging in an upright position without stepping, arm swinging with stepping, and walking on the floor or taking a walk. The patients performed the arm swinging exercise while watching a video tape everyday for a period of 3.4 weeks. Of the 25 patients, 22 completed the exercise program. Following the program, these patients showed significant improvements in their walking times for a 20m walk (10 m, return, 10 m) (before/after=29.6/24.3 sec, p=0.002) and in the step length (before/after=43.7/50.1 cm, p<0.001). Frozen gait was a negative factor to complete the programs. Improvement of gait speed after the exercise was related with less frequency of cadence. Loss of arm swinging in PD may be associated with a disturbance in the internal rhythm formation process. Arm swinging exercises are one of the exercise methods that use rhythmic cues. This study suggests that a videotaped arm swinging-based home exercise therapy is effective in such patients.

1) To our knowledge, medical student abuse has not previously been studied in Japan.
2) In our survey, 68.5% of respondents experienced medical student abuse.
3) Several students reported that they had been frequently neglected or ignored by teaching physicians during clinical clerkships and that such attitudes discouraged them and decreased their motivation.
4) To improve the learning environment, medical educators must take action to resolve this serious issue.

OBJECTIVE: We implemented automatic online medical consultation software. It infers disease of patients with knowledge about symptoms and the epidemiologic data. And we compared its performance of inference with that of human doctors. METHODS: This software accepts information about users' age, sex, and symptoms, lists up diseases compatible with these information, and sorts diseases by probability. We implement this software with Ruby and C. RESULTS: We compared diseases listed up by this software with those that by two human doctors, and found that 1) 90% of confirmed diagnoses was included in the list this software inferred, and 2) more than 50% of diseases in the list this software inferred are same diseases as ones both of two human doctors inferred. CONCLUSION: This software can not determine final diagnosis. But this software lists up probable diseases only by interview. Then we believe this software will be useful for patients when they want to check themselves before consulting their doctor. We believe that this software will be useful for patients to check their health status.

Cardiac surgery in patients aged 90 years or older is not common. We report 2 successful cases in nonagenarians. A 90-year-old man underwent the Bentall operation for aortic root aneurysm with moderate aortic valve regurgitation. A 91-year-old man underwent aortic valve replacement and single CABG (LITA to LCX) for severe aortic valve stenosis with single coronary artery disease. Their postoperative courses were uneventful. We emphasize that cardiac surgery in nonagenarians should not be withheld on the basis of age alone, but should be based on careful assessments of the relative medical risks and benefits, as well as the wishes of the patient and family.

Characteristics of low attenuation area (LAA) of the lungs on HRCT were studied in 132 patients with asthma, and long-term spa therapy on the LAA of the lungs was observed in 5 patients with asthma, whose me an %LAA was more than 30%.
1. The morphology of LAA of the lungs on HRCT observed in asthma was different from that in pulmonary emphysema. 2. The LAA of the lungs in asthma was closely related to residual volume (RV). 3. The mean %LAA value significantly decreased from 33.5% before spa therapy to 24.5% at 24 months after beginning of the therapy. CT number also significantly increased after long-term spa therapy. 4. %FEV1.0 value significantly improved from 52.1% before spa therapy to 72.1% at 24 months after spa therapy. The RV value also decreased by spa therapy, however, the decrease was not significant. These results suggest that LAA of the lungs in asthma is associated with hyperinflation, and the LAA of the lungs decreases after long-term spa therapy.

Clinical effects of spa therapy for patients with pulmonary emphysema (PE) were evaluated by observing changes in %LAA of the lung on HRCT, %RV, %FVC, %FEV 1.0, and %DLco values after the long-term therapy. The subjects in this study 16 patients with PE. The subjects were divided into two groups according to the extent of %LAA<-950 HU of the lung on HRCT: %LAA<50% (N=6) and 50%≤%LAA (N=8). 1. Spa therapy significantly improved %LAA (42.5% at the initial stage to 36.3% 24 months after spa therapy), %RV (202.1% to 156.1%) and %DLco 71.0% to 85.7%), but not %FVC and %FEV 1.0, in patients with PE of %LAA<50%, however, significant. Improvement of these parameters was not observed in patients without spa therapy. 2. Spa therapy did not improve the values of %LAA, %RV, and %DLco, as well as %FVC and %FEV 1.0, in patients with PE of 50%≤%LAA. These parameters tended to decrease in the patients of 50%≤%LAA. These results suggest that spa therapy improves %LAA and parameters related to pulmonary function when they are at early stage of PE, however, the therapy was not remarkably effective for these parameters when they were at advanced stage of PE.

A 13-year-old girl with asplenia syndrome who previously had undergone left subclavian-to-pulmonary artery shunt after removal of a cavopulmonary shunt with interposition of a short segment of the left superior vena cava was admitted for congestive heart failure. Angiography revealed aneurysmal dilatation of the left superior vena cava. Percutaneous coil embolization of the shunt was successfully performed and the venous aneurysm was diminished. Interposition of a venous component in systemic-to-pulmonary artery shunt should be avoided even after removing a cavopulmonary shunt.

Up until the present, the primary treatment for threatened premature labor has been bed rest, with drug therapy as a supplement. However, with drug therapy the problems of side effects and dosage limitations have made it difficult to achieve therapeutic effectiveness. In this paper, the authors report the favorable results obtained in such cases when moxibustion and a microwave emitter were used for stimulation therapy based on Oriental medical theory. Moxibustion was carried out on Shim, Yusen and Saninko (acupuncture points) in cases of threatened premature labor beyond the 24th week. Despite the short duration of treatment, uterine tension was relieved, fetal movement increased, and resistance in the umbilical artery and uterine artery reduced. Similar results were achieved with multiple microwave stimulation treatments; the effects lasted for long periods and were not accompanied by side effects. Thus, the results showed that through the use of moxibustion therapy in conjunction with drug therapy, the dosage could be reduced, and the frequency of side-effect appearance lowered. These results suggest that moxibustion therapy has potential as an effective and safe new treatment for threatened premature labor.

Correction of fetal malpresentation such as knee-chest positioning and external cephalic version, has long been performed in cases of breech presentation. The reliability and safety of such treatment, however, remains unclear. We performed moxibustion on three acupoints, namely, Saninko, Shiin, and Yusen to correct the condition.
We studied a total of 28 women, 22 of whom were observed until delivery, and six who had not reached full term by the end of the study. Cephalic presentation was achieved in 25 (89.3%), All but one of the fetuses that were corrected to cephalic presentation had full term vaginal delivery. The remaining one underwent premature delivery due to premature rupture of the membrane at 35 weeks 6 days. None of the babies showed any abnormalities. Correction could not be achieved in three women by the time of delivery. One of these three had dicornate uterus and underwent caesarian section due to premature rupture of the membrane. The other two had full term vaginal delivery of live babies. These results indicate that the correction of breech presentation by moxibustion is a safe method which cause no adverse effects on the mother or baby.
