This paper describes a clinical review of cases of gastric cancer treated surgically at the Department of Surgery of the Shirakawa Kosei General Hospital, the core medical institution in the southern part of Fukushima Prefecture.
During the period of 20 years from January 1981 through December 2000, a total of 1, 132 cases were operated on for gastric carcinoma. Surgical resection cases totaled 1, 023 (resection ratio: 90.4%); curative resection cases, 894 (curative resection ratio: 79.0%); 5-year survival rate for resection cases, 68.3%; and 5-year survival rate for curative resection cases, 75.6%. When the cases were divided into those treated during the first half of the 20 years nad those treated during the latter half of the 20 years, the number or resection cases was smaller during the latter than during the first half but the resection ratio was larger. The early stomach cancer cases in terms of the degree of progress, histological classification, depth and metastasis to lymph nodes have been increasing and the 5-year survival rate has been on the rise.

A medical-ethics course was anonymously evaluated by first-year students over 2 years. The course emphasizes problem-based learning through group discussion of clinical cases and lectures on ethical issues. A tutorial system was added to the course in the second year. Students' evaluations indicated that most students had positive attitudes about the course and that both group discussion and lectures were helpful for achieving the general instructional objectives and specific behavioral objectives of the course. A comparison of the 2 years showed that a majority of evaluated items received higher evaluations from second-year students than from first-year students. We attribute the difference to the livelier discussion with the introduction of the tutorial system and the smaller discussion groups. These results indicate that students consider medical-ethics education to be useful.

Our medical ethics course emphasizes problem-based-learning (PBL) via group discussion of clinical cases. The significanceof instructors' assessments of PBL in ethics education was studied with different assessment tools during thelast 2 years. In the first year, students' behavior and level of functioning in group discussion were assessed on a group basiswith an 8-item instrument. In the second year, students' level of functioning and flexibility in response to differentopinions in group discussion were assessed on an individual basis with a 2-item instrument. Instsments ofstudent's performance in group discussion were positively but weakly correlated with scores of their reports derivedfrom group discussions. Instructors could consistently assess student performance in PBL in terms of behavior and levelof functioning in group discussions. Furthermore, instructors rated flexibility in response to other opinions as an importantfactor in group dynamics, including interaction between students and instructors. These results suggest that instructors'assessments can be used to help evaluate students in a medical ethics course. Instructors' assessments of studentflexibility during PBL can be particularly useful in this regard.

Objective:
To assess the noncontrast two-dimensional single-shot balanced turbo-field-echo magnetic resonance angiography (b-TFE MRA) features of the abdominal aortic aneurysm (AAA) status following endovascular aneurysm repair (EVAR) and evaluate to detect endoleaks (ELs).
Materials and Methods:
We examined four aortic stent-grafts in a phantom study to assess the degree of metallic artifacts. We enrolled 46 EVAR-treated patients with AAA and/or common iliac artery aneurysm who underwent both computed tomography angiography (CTA) and b-TFE MRA after EVAR. Vascular measurements on CTA and b-TFE MRA were compared, and signal intensity ratios (SIRs) of the aneurysmal sac were correlated with the size changes in the AAA after EVAR (AAA prognoses). Furthermore, we examined six feasible b-TFE MRA features for the assessment of ELs.
Results:
There were robust intermodality (r = 0.92–0.99) correlations and interobserver (intraclass correlation coefficient = 0.97–0.99) agreement. No significant differences were noted between SIRs and aneurysm prognoses. Moreover, “mottled high-intensity” and “creeping high-intensity with the low-band rim” were recognized as significant imaging findings suspicious for the presence of ELs (p < 0.001), whereas “no signal black spot” and “layered high-intensity area” were determined as significant for the absence of ELs (p < 0.03). Based on the two positive features, sensitivity, specificity, and accuracy for the detection of ELs were 77.3%, 91.7%, and 84.8%, respectively. Furthermore, the k values (0.40–0.88) displayed moderate-toalmost perfect agreement.
Conclusion
Noncontrast MRA could be a promising imaging modality for ascertaining patient follow-up after EVAR.

Adverse Drug Reaction Relief System is intended for people who suffer adverse health effects from drugs despite their proper use, including over-the-counter (OTC) drugs. The decision-making data for the payment of relief benefits associated with OTC drugs and the instructions-for-use provided by community pharmacists and registered retailers were investigated. The results showed that the relief benefit nonpayment rate for OTC drugs was 3.9% and the number of cases was 9, of which 5 were due to improper use. Among the OTC drugs covered by relief benefits, the most common were schedule II pharmaceuticals, which were sometimes used in combination with prescription drugs. These results suggest that pharmacists and registered retailers should check for the use of concomitant drugs (e.g., with drug notebooks) at the time of the OTC drug sale. Pharmacists and registered retailers should provide a detailed explanation of the drugs to consumers and confirm that the information is understood, especially when schedule II pharmaceuticals or psychotropic drugs are sold. Additionally, information on the initial symptoms of an adverse drug reaction and treatment should be provided to prevent serious reactions. Follow-up with consumers during OTC drug use may also reduce the risk of misuse.

Objectives: “Adverse Drug Reaction Relief System” (hereinafter called the Relief System) has been established to provide prompt relief to patients experiencing health damage caused by adverse drug reactions. Since 2018, the Relief System has required community pharmacies that acquire additional points as local support system to actively report adverse drug reactions. Here, we investigated the recognition and utilization of the relief system among community pharmacists.Method: A questionnaire survey was conducted among community pharmacists between August 1 and September 30, 2019.Results: The survey achieved a response rate of 58.1%. The recognition rates of the relief system and Pharmaceuticals and Medical Devices Agency (PMDA) as its application destination were 98.9 and 74.5%, respectively. Of the community pharmacists, 2.6% had experience in utilizing the relief system; and 8.8% did not want to recommend the utilization of the relief system for patients mainly because of the “low recognition of the system” and “the complicated and troublesome preparation of the necessary documents such as medical certificates.” The community pharmacists who acquire additional points as local support system, compared with those who do not, achieved significantly higher rates in two items, including that for preparation of the documented procedures pertaining to adverse drug reactions.Conclusion: Despite the high recognition of the relief system among community pharmacists, the percentage of pharmacists with experience in actually utilizing the relief system and applying to the PMDA was low. One reason that the use of the relief system was not widespread was the low recognition particularly of the destination and procedures of reports on adverse drug reactions. In the future, educational campaigns to improve pharmacists’ comprehension of the relief system will be needed. Moreover, pharmacists must play a central role in enhancing the recognition of the public relief system and promoting medical safety.

Objectives: The long treatment duration of glaucoma and multiple drug use have decreased patient adherence to anti-glaucoma drugs. This has prompted the recent marketing of a combination drug, Xalacom ® Combination Eye Drops (hereinafter referred to as the original drug), and its generic drugs (3 generics). In this study, we compared these eye drops from a pharmaceutical viewpoint,conducted research on usability, and evaluated the selection criteria for generics.Methods: The viscosity and pH of the original drug and its generics were measured. The total number of drops per container, mean mass per drop, and the squeeze force needed for one drop of individual eye drops were measured using a digital force gauge. In addition, a questionnaire survey on the usability of each eye drop was conducted in patients.Results: The total number of drops in the contain of the original drug and generics tested almost the same. The mean mass per drop of generics from two companies was significantly lower than that of the original drug, and the squeeze force of the generic from one company was significantly lower than that of the original drug. The usability of the containers some generics was significantly higher than that of the original drug.Conclusion: No difference was observed in the total number of available drops between the original drug and generics. However,differences in squeeze force and usability were observed between the original drug and generics and among the generics. This information should preferably be described in the interview form, patient instruction manual, etc. for providing medication instructions to pharmacists. All products investigated in this study contained more than 100 drops in the containers. The expiration date of tested eye drops after opening is about one month. Reducing the volume of filling into a container may be contribute to the medical economy and avoid the risk of microbial contamination.
