We report a case of malignant lymphoma of the duodenum with right atrial invasion. A 71-year-old man presented with anemia and exertional dyspnea. Gastric fibroscopy showed a duodenal tumor pathologically diagnosed as diffuse large B-cell lymphoma (DLBCL). Echocardiography showed a large right atrial tumor. We performed urgent surgery to prevent a tumor embolism. As the tumor was firmly attached to the atrium, septum and ascending aorta, we performed partial resection to improve the patient's hemodynamics status. Pathologic findings showed DLBCL. Systemic chemotherapy induced partial remission with out any cardiac recurrence.

Metformin is widely prescribed for patients with type 2 diabetes mellitus (DM). Its use for patients with type 1 has been considered a contraindication because of possible adverse effects such as lactic acidosis. However, metformin has been recently used with insulin therapy to reduce insulin-dose requirements in Type 1 DM.
An 81-year-old Japanese woman with type 1 DM was treated with insulin and metformin. She was admitted to our hospital due to altered mental state and hypotensive shock via a referral from her primary care physician. The patient had severe lactic acidosis and acute kidney injury with hyperkalemia with the suspected cause being the use of metformin. She was treated successfully with hemodialysis (HD).
Although the independent predictive factor of mortality due to metformin-associated lactic acidosis is a prothrombin time (PT) activity of less than 50% in 24 hours, we recommend that HD should be performed for a patient with severe lactic acidosis even if the initial PT activity is normal.

A 3-month-old girl of univentricular heart of left ventricular type with atresia of left atrioventricular valve (LAVV) and coarctation of the aorta (Co/AO) is presented. UCG and angiography revealed concordant AV connection with straddling RAVV with transposed great arteries [SDDT]. The following pressures (in mmHg) were noted on catheterization: RA mean 1 (a=3, v=1), LA mean 12 (a=17, v=14), LV 84/0/8, Ao 81/41, and PA 74/39. Patent foramen ovale (PFO) was restrictive and balloon atrioseptostomy was not feasible. Blalock-Hanlon atrial septectomy (8×6mm), subclavian flap aortoplasy (SFA) and pulmonary arterial banding were performed simultaneously under bilateral thoracotomy. Acute renal failure occurred after surgery and the girl required peritoneal dialysis for 5 days. At 6 months after surgery, girl is doing well. There will be a predictable fall in pulmonary vascular resistance after atrial septectomy and SFA with a ligation of PDA may result transient increase in systemic resistance. Therefore, atrial septectomy and SFA in conjunction with pulmonary arterial banding should be done simultaneously.

Fourteen cases (ranged 4 days to 5 months old, mean=40 days old) of coarctation of thoracic aorta underwent subclavian flap aortoplasty were between Jan. 1986 and Dec. 1990. Early postoperative course in these patients was reviewed retrospectively. In 9 cases of these patients, complex intracardiac anormalies co-existed (VSD in 7, ECD in one, single ventricle with MA in one). Preoperative pressure gradients between upper and lower extremities were 40±7mmHg and the gradients were significantly reduced after the repair of coarctation (8±4mmHg). Serum creatinine phosphokinase (CPK) increased postoperatively reaching peak levels by day 3 (12, 315 ±8, 462IU/l) and then gradually decreased. Gultamic oxaloacetic transaminase (GOT), glutamicpyruvic transanmiase (GPT), serum urea nitrogen (BUN) and serum creatinine (S-Cr) also increased postoperatively. When patients were divided into two group following the maximum CPK levels (group A: >4, 000; group B: <4, 000IU/l), the duration of mechanical ventilation (A: 117±21; B: 20±9hr), max. S-Cr levels (A: 2.16±0.64; B: 0.47±0.13mg/dl) and max. GPT (A: 323±127; B: 58±24IU/l) were significantly increased in group A. There was no significant correlation between these factors and postsurgical residual pressure gradients. An increase in these factors did not depend on the operation time, age, body weight and additional surgical procedures such as pulmonary arterial banding. These data suggest that the transient unbalanced blood distribution might exist even under no pressure gradients between upper and lower extremities. This might be important in the management of postoperative patients after repair of coarctation.

Objective: In the intensive care unit (ICU), drugs are administered in sequence as the conditions of the patient change rapidly, and there are often cases where many injections are administered simultaneously. For this reason, it is important to quickly select the appropriate administration route. In this study, we prepared a quick reference table for incompatibilities of frequently used and highly important injections in the ICU (referred to as the “quick reference table”) that will enable selection of the appropriate administration route, and we investigated the status of use and usefulness of this quick reference table.
Methods: The drugs included in the quick reference table were extracted from prescription records from May to October 2009, and these were finalized by discussions with the nurses in the ICU. Three reference materials were used: Manual on the Supervision of Injection Preparation (3rd Edition), Data Search on Injection Incompatibilities 2009, and MICROMEDEX®. The survey was conducted with all 12 nurses in the ICU after 4 months of distributing the quick reference table.
Results: The quick reference table included 57 pharmaceutical items, and compatibility was classified into 10 categories. The quick reference table was prepared as one A3 page for convenience. The retrieval rate of the survey was 100%. The average number of years of practical experience as a nurse was 12.2 years, and 11 out of 12 nurses used the quick reference table. Of the 11 nurses who used the table, 6 answered that it was “very useful,” while 4 answered that it was “useful.” All 11 nurses who used the quick reference table answered that they “consulted the pharmacists less frequently.”
Conclusion: Satisfactory evaluations were obtained with regard to the details included in the quick reference table, and the table was estimated to be highly useful and important even for ICU nurses with many years of experience. Furthermore, it was suggested that the quick reference table was also useful in reducing the workloads of the pharmacists.

The WHO reported the importance of IPE (Interprofessional Education) in order to implement team-based medicine smoothly. Some Japanese medical educational institutes presented their IPE programs, which involved real patients, but most IPE programs used scenario-based or standardized patients. Moreover, few reports showed IPE programs for diabetic patient education. We created a new program, called the "Diabetes education class IPE" . Participants were 2 medical, 4 nursing, 4 pharmacy, and 3 dietician students. The students experienced the planning and management of and reflection on diabetes education classes. As a result of reflection, the "Diabetes education class IPE" was viewed as a useful IPE program.

To encourage the broad use of simulation-based medical education and establish partnerships to promote objective structured clinical examinations after clinical clerkship among medical teachers, we hosted the first team-based clinical skills competition event for medical students in Japan, named ‘Medical Students' Simlympic Games 2014'. Thirty-six (12 teams of three) open-recruited 5th or 6th grade medical students participated in this event. Student teams performed clinical tasks at 6 stations, which actively utilized the strengths of simulators or simulated patients. Contents, composition, difficulty level, and validity were tested by trainee doctors and examined by committee members in advance. In this report, we describe our concept, executive committee formation, a variety of arrangements, the outline on the day of the event, and the results of a questionnaire targeting participants.

To the best of our knowledge, there are few reports on acquirement of medical skills of infection control using a scenario simulation program. We report the development of a education program using scenario-based simulation named Infection Control Training Course (ICTC). The three main aims of this course are basic comprehension of standard precautions and contact precautions, acquirement of skills for wearing and removal of personal protective equipment (PPE), and precise selection of PPE for various situations.
・For the materials and methods, 225 medical staff members taking part in the ICTC at TMU participated in the study. Investigations using a questionnaire about standard precaution, contact precaution and PPE selection were carried out for the pre-course and post-course of the day. In addition, the satisfaction level was evaluated using free score text.
・The return rates of the completed questionnaire for investigating these areas were 88.4% (pre-course) and 95.1% (post-course). Among all the items investigated, improvements were verified statistically (Wilcoxon signed-rank test). The satisfaction level was 94.7 ± 9.4 points.
・In conclusion, the ICTC was considered to be effective for acquiring medical skills of infection control, particularly basic comprehension regarding standard precaution, contact precaution and precise PPE selection using a scenario simulation program.

Object: A multicenter survey was conducted to investigate the status of use of supplements and related problems in patients with diabetes mellitus.
Methods: A questionnaire was mailed to institutions where members of the Drug Information Section, Tokyo Hospital Pharmacists Association, worked, and hospitalized patients with diabetes mellitus were surveyed with a questionnaire.
Results: The response rate of the questionnaire was 85%, and 22 patients reported taking supplements. The most common motivation to purchase supplements was a recommendation from an acquaintance, followed by a recommendation from a family member and TV. Only 9.1% of the patients consulted healthcare professionals when purchasing supplements. The patients who did not follow the dosage and administration instructions and those who were not aware of precautions regarding proper use accounted for 31.8% and 63.6%, respectively. The proportion of patients who did not inform their physicians about the use of supplements was 65.2%, and 4.5% reported some health damage (rash).
Conclusion: Our results revealed that supplements were used without careful consideration and were not administered properly, suggesting that scientific evaluation of efficacy and safety was warranted in future studies. It is important for pharmacists to actively collect information on patient use of supplements and share the information within the medical team.

Clinical course and outcome of 34 patients with peripheral and visceral artery aneuryms, operated during 1975-1990, were analysed. There were 24 males and 10 females. Ages ranged from 14 to 87, with an average of 55 years. Peripheral aneurysms located most frequently in the lower extremity, and the incidence of various origin of the aneurysms were as follows: 14 in femoral, 5 in popliteal, 4 in internal iliac, 3 in subclavian, 2 in common iliac arteries, and 1 in each of vertebral, radial, splenic, renal and anterior tibial artery. Most common cause of aneurysm was arteriosclerosis. Multiple aneurysms were found in 59% of sclerotic type and in most of these with bilateral aneurysms in the iliac, femoral and popliteal. Ruptured aneurysms were seen in 26% of this series. Most of the aneurysms in the extremities were totally excised without difficulty, while the aneurysms in common iliac and internal iliac were opened with partial excision or obliterated with endoaneurysmorrhaphy. Arterial reconstruction was performed using saphenous vein graft or synthetic vascular graft, excepting that the internal iliac artery itself was not reconstructed. The early operative results were satisfactory, but late results showed two death and three complications of cardiovascular system. Therefore, careful follow up of the postoperative patients was recommended.
