Introduction: This study aimed to survey patients on polypharmacy regarding their own intention and inclination to reduce medication use, and their subjective understanding of drug effectiveness and side effects. We aimed to contribute to the establishment of an information base to address polypharmacy.Methods: We enrolled 100 adult patients who had been admitted and administered ≥ 5 oral medications. A questionnaire was utilized to assess their willingness and inclination to reduce their medications, as well as their subjective understanding of drug effectiveness and side effects.Results: Sixty-two patients expressed an intention to reduce their medication use, citing reasons including medication management, drug combinations, and side effects. The proportion of patients with this intention increased as the number of prescribed medications increased. Of the 38 individuals who responded that they had no intention of reducing their medication, 21 (55.3%) cited the reason as being that they received the prescription from a physician. The level of understanding about the effectiveness of their own medications was significantly lower among those aged ≥ 75 years. However, the level of understanding of side effects did not vary based on age or number of prescriptions.Conclusion: To promote the optimization of prescriptions, it is necessary to ascertain patients' intentions, and the relationship between patients and prescribing physicians.

Background/Aims: Bleeding is a complication of endoscopic snare papillectomy for ampullary tumors. This study aimed to investigate the clinical efficacy of hypertonic saline-epinephrine (HSE) local injection before endoscopic papillectomy for prevention of bleeding. Methods: We retrospectively reviewed the data of 107 consecutive patients with ampullary tumors who underwent endoscopic papillectomy. The rates of en bloc resection, pathological resection margins, and prevention of immediate or delayed bleeding in the simple snaring resection group (Group A) and the HSE injection group (Group B) were compared. Results: A total of 44 and 63 patients were enrolled in Groups A and B, respectively. The total complete resection rate was 89.7% (96/107); the clinical complete resection rates in Group A and Group B were 86.3% (38/44) and 92.1% (58/63), respectively (p=0.354). Post-papillectomy bleeding occurred in 22 patients. In Groups A and B, the immediate bleeding rates were 20.5% (9/44) and 4.8% (3/63), respectively (p=0.0255), while the delayed bleeding rates were 7% (3/44) and 11% (7/63), respectively (p=0.52). The rates of positive horizontal and vertical pathological margin in both groups were 27% and 16%, respectively. Conclusions HSE local injection was effective in preventing immediate bleeding and was useful for safely performing endoscopic papillectomy for ampullary tumors.

Lenalidomide (LD) was reported to increase the risk of thromboembolism when it was used along with dexamethasone (DEX). Prophylactic administration of antithrombotic drugs against thromboembolism has been recommended for proper use of LD, but none of the recommendation is stated in the package insert. The purpose of this study was to elucidate the usage of acetylsalicylic acid (ASA) for lenalidomide medication in patients withmultiple myeloma. We used the MDV analyzer to investigate clinical data retrospectively. The investigation period was from October 1, 2016 to September 30, 2017. Subjects were outpatients aged 20 years or older who were recorded in clinical data as multiple myeloma. There were 7,590 outpatients with multiple myeloma. They were divided into 4 groups by the combined use situation of LD and DEX: LD/DEX non-use group (n＝5,462), DEX alone group (n＝632),LD alone group (n＝203), and LD/DEX together group (n＝1,293), respectively. The prevalence rate of thromboembolism was 7.3% in the DEX alone group and 16.9% in the LD/DEX together group (p＜0.0001). Among the LD/DEX together group, ASA was prescribed at 63.6% in the group without thromboembolism (n＝1,074). The prevalence rate of thromboembolism was higher in the LD/DEX combined group than in the DEX alone group. Considering these findings, risk management for thromboembolism caused by administration of antithrombotic drugs should be considered. It is necessary to create more evidence concerning the necessity of administration of antithrombotic drug in combination with LD/DEX medication.

We have developed a new gait assisting device for patients with hemiplegia, by which a single therapist alone can work with : 1) swing of the paretic limb, 2) stance of the paretic limb, and 3) alternate lateral weight-shift during gait. This device (ASSWS : Assistance of Swing, Stance and Weight Shift) imitates the kinesiological complex (patellar ligament, quadriceps, iliotibial ligament and gluteus maximus) to maintain a standing posture for the lower extremities. We compared the results of a gait analysis using a motion analyzer for gait with ASSWS and gait without ASSWS. With ASSWS, the walking speed was faster, stride length was longer, and stride duration was shorter. No differences in floor reaction force were identified. With ASSWS, the flexion peak of the hip joint became larger and the knee joint was in a more flexed position throughout the walking cycle. Also, the joint moment of hip extension, hip flexion and knee extension all increased with use of the ASSWS.

OBJECTIVEExposure to polychlorinated biphenyls (PCBs) is considered to have culminated between 1950 and 1970 in Japan, and exposure through diet, the major exposure route, has decreased significantly over the last 10 years. The primary goal of the present study was to investigate the long-term trends and congener profiles of serum and dietary levels of PCBs using historical samples.

METHODSUsing banked samples collected in 1980, 1995, and 2003 surveys, we determined the daily intakes and serum concentrations of 13 PCB congeners (#74, #99, #118, #138, #146, #153, #156, #163, #164, #170, #180, #182, and #187) in women.

RESULTSThe total daily PCB intake [ng/day, geometric mean (geometric standard deviation)] decreased significantly from 523 (2.5) in 1980 to 63 (3.2) in 2003. The serum total PCB level (ng/g lipid) in women <40 years of age decreased significantly from 185 (1.8) in 1980 to 68 (1.8) in 2003. In contrast, the level in women >50 years of age increased significantly from 125 (1.7) in 1980 to 242 (1.7) in 2003. Specifically, the serum concentrations of hexa (#138, #146, #153, #156, #163, and #164) and hepta (#170, #180, #182, and #187) congeners increased significantly. A comparison of the serum PCB levels of women born from 1940 to 1953 revealed that their serum total PCB level was significantly higher in the 2003 survey [242 (1.7), n = 9] than in the 1995 [128 (2.0), n = 17] surveys. This increase in the total PCB level was attributable to increases in the hepta congener groups.

CONCLUSIONPresent results suggest a decreased rate of elimination of hepta congeners with aging in females, rather than a birth-generation phenomenon.

A 72-year-old man was referred to our hospital because of lumbago and an abdominal aortic aneurysm (AAA). Computed tomography revealed the AAA to be 5cm in diameter with a retroperitoneal hematoma. A diagnosis of chronic contained rupture of an AAA was made, and an operation was performed. At laparotomy, a punched-out defect (10×20mm) that was thought to connect the thrombosed aneurysm to an organized retroperitoneal hematoma was discovered on the right side of the aorta. The aneurysm was replaced with a Y-shaped prosthetic graft. The patient's postoperative course was uneventful. This case of chronic contained rupture of an AAA was distinctly different from cases of acute rupture. Although patients with chronic contained rupture of an AAA are hemodynamically stable, such cases should be assessed and treated as quickly as possible because of the risk of re-rupture.

A program for teaching basic clinical skills to fifth-year medical students was started at Toyama Medical and Pharmaceutical University in 1999. The five units of basic clinical skills included: 1) medical interviewing, 2) general physical examination, 3) chest examination, 4) abdominal examination, and 5) neurologic examination. The educational strategies and evaluations in each unit consisted of: 1) lectures, 2) videotape demonstrations, 3) role-playing in small groups, 4) practice on patients in small groups, 5) written examinations, and 6) objective structured clinical examinations. The students evaluated each session of the program with a five-grade rating scale and comments. Small-group sessions (role play and practice on patients) and objective structured clinical examinations received the highest scores, followed by videotape demonstrations. Lectures received significantly lower scores than did other parts of the program. In addition, most students recommended standardization of educational content, increased practice time, and fewer lectures. We conclude that evaluation by students is essential for improving programs for teaching basic clinical skills.

Left ventricular myxoma is very rare and only 13 cases have been reported in Japan. A 14-year-old girl was admitted to a local hospital in November, 1983, with a sudden onset of right hemiparalysis. Two-dimensional echocardiograms and left ventricular angiograms revealed two left ventricular tumors. The patient was transferred to our hospital for the operation which was performed one month later. Two tumors originating from the apical interventricular septum were removed with resection of the septum through a left ventriculotomy. The tumors were 2.0×1.7cm in size and 1.9g in weight, 1.9×1.5cm in size and 1.1g in weight, respectively. The pathological diagnosis was myxoma. Her postoperative course was uneventful, and there has been no recurrence for 15 years after surgery. Japanese literature on the subject was reviewed.
