We conducted experimental classes in an elementary school to examine how the advantages of using stereoscopic 3D images could be applied in education. More specifically, we selected a unit of the Tumulus period in Japan for sixth-graders as the source of our 3D educational materials. This unit represents part of the coursework for the topic of Japanese history. The educational materials used in our study included stereoscopic 3D images for examining the stone chambers and Haniwa (i.e., terracotta clay figures) of the Tumulus period. The results of our experimental class showed that 3D educational materials helped students focus on specific parts in images such as attached objects of the Haniwa and also understand 3D spaces and concavo-convex shapes. The experimental class revealed that 3D educational materials also helped students come up with novel questions regarding attached objects of the Haniwa, and Haniwa's spatial balance and spatial alignment. The results suggest that the educational use of stereoscopic 3D images is worthwhile in that they lead to question and hypothesis generation and an inquiry-based learning approach to history.

Background: Task-specific dystonia (TSD) confined to the lower extremities (LE) is relatively rare. This report describes dystonia confined to the LE only during forward walking. This case required careful neurological and diagnostic assessment because the patient was taking several neuropsychiatric drugs that cause symptomatic dystonia, such as aripiprazole (ARP).Case: A 53-year-old man visited our university hospital with a complaint of abnormalities in the LE that appeared only during walking. Neurological examinations other than walking were normal. Brain magnetic resonance imaging revealed meningioma in the right sphenoid ridge. The patient had been treated for depression with neuropsychiatric medications for a long time, and his abnormal gait appeared about 2 years after additional administration of ARP. After the meningioma was removed, his symptoms remained. Surface electromyography showed dystonia in both LE during forward walking, although his abnormal gait appeared to be accompanied by spasticity. The patient was tentatively diagnosed with tardive dystonia (TD). Although dystonia did not disappear clinically, it was alleviated after discontinuing ARP. Administration of trihexyphenidyl hydrochloride and concomitant rehabilitation improved his dystonia until return to work, but some residual gait abnormalities remained.Discussion: We report an unusual case of TD with task specificity confined to the LE. The TD was induced by the administration of ARP in combination with multiple psychotropic medications. Careful consideration was required for clinical diagnosis, rehabilitation, and assessment of its relevance to TSD.

【Background/Purpose】 The deep brain stimulation of subthalamic nucleus (STN-DBS) is a surgical treatment for Parkinson's disease (PD) to reduce off-state. There have been scarce reports that indicate the effectiveness of postoperative rehabilitation on the axial symptoms. The purpose of this study is to examine the effectiveness of postoperative rehabilitation in PD patients.【Methods or Cases】 The data of 31 postoperative PD patients who received 2 week physical therapy from May 2017 to May 2018 were extracted from a prospectively maintained database, and were analyzed retrospectively. Outcome measures were the Mini-Balance Evaluation Systems Test (Mini-BESTest), Trunk impairment scale (TIS), Leg extension torque, 10 times toe tapping (10TTT) and Treadmill gait analysis. The patients were evaluated at pre-operation, post-operation and discharge period. One-way repeated measures analysis of variance (ANOVA) and post-hoc Paired t-tests with Bonferroni adjustment for multiple comparison were used to analyze the data (P < 0.05).【Results】 The ANOVA showed that all clinical data had the significant differences among three periods. The post hoc test revealed that there were significant differences between pre-operation and discharge periods in the Mini-BESTest (P < 0.0001), TIS (P < 0.0001), Step length on the Treadmill (P=0.004) and 10TTT (P=0.009), but the lower limb extension torque (P=0.11). There was only significantly different between pre-operation and post-operation in the Step length on the Treadmill (P=0.032). 【Discussion/Conclusion】 The results showed that postoperative rehabilitation has a positive effect on the balance ability, trunk function, gait function and limb akinesia of the PD patients. These facts might indicate that STN-DBS and postoperative rehabilitation provide different effects on the PD patients.【Ethical consideration】This study was conducted with the declaration of Helsinki. This study was approved by the institutional ethics review board (JHS 18-007).

Although improving energy metabolism in ischemic brain has been accepted for the treatment of cerebrovascular diseases, administration of glucose, as an energy substrate, would aggravate ischemic brain damage via activating anaerobic glycolysis, which leads to lactate accumulation. β-hydroxybutyrate (BHB) is one of the ketone bodies that can be utilized as an energy source during starvation. The purpose of our study was to define the protective effects of BHB on brain damage induced by hypoxia, anoxia and ischemia. The isotonic solution of BHB administered 30 min before the induction of ischemia at doses over 50 mg · k g −1 · h −1 showed remarkable protective effects against hypoxia and anoxia. BHB administered immediately after a bilateral carotid artery ligation at a dose of 30 mg · kg−1 · h −1 significantly suppressed the elevation of cerebral water and sodium contents as well as maintaining high ATP and low lactate levels. In contrast, glycerin, a hypertonic agent, substantially reduced the water content but did not show any significant effect on other parameters. We demonstrated that BHB, unlike glycerin, when used as an energy substrate in ischemic brain, has protective effects on cerebral hypoxia, anoxia and ischemia-induced metabolic change.
