OBJECTIVE: To retrospectively evaluate the frequency and risk factors for developing thrombus in a systemic vein such as the infrarenal inferior vena cava or the iliac vein, in which a balloon-occluded retrograde transvenous obliteration (B-RTO) catheter was indwelled. MATERIALS AND METHODS: Forty-nine patients who underwent B-RTO for gastric varices were included in this study. The B-RTO procedure was performed from the right femoral vein, and the B-RTO catheter was retained overnight in all patients. Pre- and post-procedural CT scans were retrospectively compared in order to evaluate the development of thrombus in the systemic vein in which the catheter was indwelled. Additionally, several variables were analyzed to assess risk factors for thrombus in a systemic vein. RESULTS: In all 49 patients (100%), B-RTO was technically successful, and in 46 patients (94%), complete thrombosis of the gastric varices was achieved. In 6 patients (12%), thrombus developed in the infrarenal inferior vena cava or the right common-external iliac vein. All thrombi lay longitudinally on the right side of the inferior vena cava or the right iliac vein. One of the aforementioned 6 patients required anticoagulation therapy. No symptoms suggestive of pulmonary embolism were observed. Prothrombin time-international normalized ratio and the addition of 5% ethanolamine oleate iopamidol, on the second day, were related to the development of thrombus. CONCLUSION: Development of a thrombus in a systemic vein such as the inferior vena cava or iliac vein, caused by indwelling of the B-RTO catheter, is relatively frequent. Physicians should be aware of the possibility of pulmonary embolism due to iliocaval thrombosis.

To smoothly proceed with the national policies and projects concerning dementia measures, it is important that pharmacists who take care of patient in clinical practice sufficiently understand its contents. In this study, we conducted a questionnaire survey involving chain community pharmacists to investigate the level of awareness concerning these policies and projects. Subjects were 446 chain community pharmacists. The questionnaire consisted of 17 items (e.g. the level of awareness regarding the “Comprehensive Strategy to Accelerate Dementia Measures (New Orange Plan)”, “Dementia Supporters Caravan Program (Caravan Program)”, and “Dementia training certified pharmacist program (Certification program)”). The questionnaires were filled out anonymously. The levels of awareness concerning the “New Orange Plan” and “Caravan Program” were 34.7% and 48.9%, respectively. Sixty-one percent of subjects attended a “Dementia Supporter Training Lecture”, 30.4% of whom were wearing the “orange ring”. The levels of awareness and the hope of acquisition concerning the “Certification program” were 47.8% and 79.8%, respectively. To achieve the purpose of “contribution to early detection of dementia by pharmacist” of the “New Orange Plan”, it is necessary to conducting the workshop and to create an opportunity to come in contact with dementia patients. It is also important to recognize that it is necessary to enlighten the meaning of wearing an “orange ring” and to enlarge the circle of dementia supporters. In addition, it is thought that more dementia patients can be supported in the community by increasing the levels of awareness concerning the “Certification program” and giving appropriate advice and response.

Objective: Glaucoma is the most frequent cause of blindness in Japan and is primarily treated using IOP-lowering ophthalmic solutions. Although the patients themselves frequently instill ophthalmic solutions, instillation by caregivers may be necessary for various reasons. Therefore, we evaluated pharmaceutical characteristics of antiglaucoma ophthalmic solutions and their usability from the caregivers' viewpoint.Methods: Five dorzolamide hydrochloride-timolol maleate ophthalmic solutions and 2 travoprost-timolol maleate ophthalmic solutions were evaluated concerning the pharmaceutical characteristics and subjective squeezability rated by adults aged 20 years or above.Results: Among the dorzolamide hydrochloride-timolol maleate compounding ophthalmic solutions, the squeeze force was the lowest in COSOPT® ophthalmic solution (11.8 N), and DORMOLOL® combination ophthalmic solution NITTEN was rated highest, with 68.2% of the subjects placing it within the top 3 levels of a 7-level scale. Of the travoprost-timolol maleate ophthalmic solutions, the squeeze force was 9.8 N, lower than the pioneer drug, in TraTimo® combination ophthalmic solution NITTO, which was also rated in the top 3 levels by 90.3% of the subjects. A strong negative correlation was observed between the squeeze force and squeezability.Conclusion: In instillation by caregivers, the squeeze force was shown to be correlated with subjective squeezability as in instillation by patients themselves. This study provided information concerning the usability of ophthalmic solutions from the caregivers' viewpoint. For the future, it is necessary to select ophthalmic solutions from the caregivers' as well as the patients' viewpoints by utilizing information obtained in this study.

Background:
Dual SC screw (DSCS) is a unique concept internal fixation device consisting of a sliding screw and barrel assembly that enables compression force to be applied to the femoral neck fracture side. There are two types of barrels: a thread barrel and a plate barrel that has a one-holed side plate to prevent varus deformity. We report clinical results of the application of a DSCS with combined use of a thread barrel screw as an anti-rotational screw and a plate barrel screw as a compression hip screw.
Methods:
We used DSCS for femoral neck fractures in 196 hip joints of 190 patients between November 2005 and June 2017. Among them, 70 hips in 66 patients (13 men and 53 women; mean age, 73.2 years) were followed up for at least 24 months. There were 53 nondisplaced fractures (Garden’s classification stage 1 or 2) and 17 displaced fractures (stage 3 or 4). We evaluated the postoperative walking ability of the patients who were followed up for at least 24 months and examined details of all complications.
Results:
The mean follow-up period was 37.4 months (range, 24–144 months). Forty-two (64%) out of the 66 patients who were followed up for at least 2 years were able to walk independently with or without a cane. The incidence of complications was 11.5% in nondisplaced fractures and 17.5% in displaced fractures, and arthroplasty was required in 5.8% and 5.0%, respectively. The most frequent complication was secondary displacement including cutout and shortening of the femoral neck, but no implants showed varus displacement.
Conclusions
The application of DSCS for the treatment of femoral neck fractures had satisfactory results. The complication rate was low, and there was no postoperative varus displacement of DSCS in either displaced or nondisplaced fractures. We suggest DSCS is a reliable option for both displaced and nondisplaced femoral neck fractures.

To reduce the stress on the medial tibial cortex and to decrease the risk of fracture, a varus cut of the tibia appears to be a reasonable alternative to the orthogonal cut by conventional methods. We present a new instrument and procedure, which enables a varus tibial cut for Oxford unicompartmental knee arthroplasty. We used a custom-made, slidable fixator instead of the standard fixator to set the extramedullary rod on the leg. We also made a numeric formula and a chart to arrange the varus cutting angle using the length of the mediolateral shift of the distal end and the longitudinal extension length of the extramedullary tibial rod. A varus cut up to 4.5° can be controlled. This technique is a simple and useful means of obtaining a varus tibial cut for Oxford unicompartmental knee arthroplasty.

Following the revision of the structure and content of the Model Core Curriculum for Medical Education to be more outcome-based and the legal status of the medical practice performed by medical students in the clinical clerkship, we have revised the Guideline for Participatory Clinical Clerkship. The following items were revised or newly described : significance of enhancing the participatory clinical clerkship, scope of medical practice, confidentiality, patient consent, patient consultation and support service, objectives of the clinical clerkship, simulation education, departments where the clinical clerkship is conducted, assessment in the clinical practice setting, CC-EPOC, and entrustable professional activities. A foundation has been established to promote seamless undergraduate and postgraduate medical education. However, future work is needed to examine the specific level of performance expected at the end of the clinical clerkship and department-specific clinical practice goals and educational strategies.
