Extended－release Oxycodone tablet has been available for cancer pain treatment since 2003 in Japan. After pure oxycodone injection became available in 2012, we have tried to switch from oral to injection when oral intake becomes difficult because of bowel obstruction, nausea or drowsiness due to progression of the disease. There is no evidence regarding the ratio of switching from oral to injection at present in Japan. We always pay attention to avoid patients drowsiness because of an overdose of opioid, because there is not enough time left for cancer patients in the terminal stage, and drowsiness takes away from the patient’s good QOL. We switched Oxycodone from oral to injection in 8 cases from June to December in 2012. At first, we assess if the patient is well controlled by oral oxycodone or not. If the patient is not relieved from the pain enough, we switch oxycodone from oral to continuous subcutaneous injection with a dose of around 75％ at first. After that we titrate the dose little by little up to an appropriate level. We were able to evaluate 5 patients out of 8 because there were 3 patients with consciousness disorder. As a result, we were able to decrease dosage to 46.4％ on average.

In atrioventricular (AV) discordance, a morphologic tricuspid valve functioning as a systemic AV valve often becomes incompetent and needs to be replaced. However, mitral valve replacement concomitant with tricuspid valve replacement is unusual in the disease. Here, we report a case of successful double AV valve replacement long after functional biventricular repair in AV discordance. A 32-year-old man with AV discordance was admitted with orthopnea. He had undergone the Rastelli procedure at age 10 and removal of the deteriorated conduit valve at age 24. Preoperative examinations revealed not only tricuspid but also mitral regurgitation. Both deteriorated valves were replaced with mechanical valves. In AV discordance after Rastelli procedure, a non-valved conduit may accelerate mitral deterioration because pulmonary hypertension from tricuspid regurgitation increases the afterload of the pulmonary ventricle.

Objectives : The present study investigates the effects of body iron stores upon indices of biosynthesis and destruction of red blood cells (RBC) induced by a single session of cycling exercise.
Design : Eight sedentary female students were divided into groups depending on their body iron stores : normal (C group, n=5) and iron deficient (D group, n=3) . Blood samples were collected at five time points of before (pre), immediately after (0 hours), then 1, 3 and 6 hours after exercise (248±31 kcal, 70% V0₂ peak level) . Osmotic fragility and serum haptoglobin (hp) concentration served as of for degradation, and δ-aminolevulinate dehydratase (ALAD) activity, erythropoietin concentration and number of reticulocytes served as indices of RBC biosynthesis.
Results : A single session of cycling exercise did not affect the level of RBC, hemoglobin, hematocrit, serum iron, ferritin, transferrin saturation, hp and osmotic fragility in either groups. The δ-ALAD activity increased at 3 (p<0.05) and 6 hours (p<0.01) after exercise compared with that at 0 hours in the C group. In contrast, δ -ALAD activity in the D group was significantly lower at 3 hours after exercise than that of C group (p<0.001) . Reticulocytes and erythropoietin concentration increased gradually in the C group after exercise, but not in the D group.
Conclusions : A single session of cycling exercise under our experimental conditions enhanced RBC biosynthesis indicated by δ -ALAD activity, whereas exercise-induced hemolysis was not evident. Body iron stores affect the δ -ALAD activity induced by a single bout of cycling exercise.

Personal lifestyles constitute one of the strategic frontiers of preventive medicine. We carried out a survey of eating habits of people in three rural communities in the southern part of Akita Prefecture, where fundamental health screening programs have been implemented regularly. Differences in eating habits between men and women and between age groups were found. The health status of the examinees was judged by using data on blood pressure, obesity and lipid levels measured at the latest health checkup.
To find a correlation between eating habits and physical health status, the frequency of illness was examined according to the number of times of eating various kinds of food. It was found that with age, people take in fish and shellfish, cow's milk, beans, vegetables, Japanese confections and soup more frequently and eat less meat. The incidence of hypertension varied by age and sex, but was higher in those who eat less soup, pickles and milk. Likewise, abnormally high levels of total serum cholesterol were found in women who eat meat, eggs and greasy food less than twice a week. It was thought that those hypertensives and those with high cholesterol values are cuttingdown on their intake of those foods of their own accord. Therefore, we would like to point out that, in the secondary prevention setting, physicians and other health care providers should know in advance whether their patients are putting themselves on a restricted diet or not.
When the average serum lipid values were examined according to the number of times of eating meat or fish and shellfish per day, it was found that men aged 70 years or above who eat those foods more than once every day have high HDL cholesterol values and that these values significantly vary depending on the kind of meat. These findings suggested that persons of advanced age who eat well and who are not particular about their food are full of vitality. This could serve as an important point in the care of the aged with serum lipid abnormalities.
A study of evacuation and its relation to vegetable intake showed that the less the frequency of bowel movements, the smaller the amount of vegetable intake. There was a significant difference in the frequency of evacuation between vegetable eaters and those who do not consume an adequate amount of fiber.

 Since the 1960s, Japanese nurses have been working as international nursing collaborators with or for the people in developing countries in order to promote health through transferring nursing knowledge and skill. However a number of nurses reported that they did not have enough competencies as international nursing collaborators. The objectives of this study were: a) to describe the experiences of Japanese international nursing collaborators whose mission was transferring nursing knowledge and skill and b) to determine their learning needs as international collaborators, and to design educational programs (graduate program) based on the results of survey. The participants of this study were twenty-seven nurses who had had an international collaborative mission and stayed in a developing country for more than one year. Semi-structured group or individual interviews were used in order to describe activities process and leaning needs as international collaborators. The interview data were analyzed using content analysis from the viewpoint of competency and learning needs. Nurses reported needs in two major areas: Fundamental Competences and Knowledge, and Required Competences for Development of International Collaborative Tasks. Fundamental Competences and Knowledge consisted of nine components: (1) cross-cultural experiences, (2) acceptance of cultural differences, (3) professional experience, (4) degree and qualifications, (5) philosophy of nursing, (6) language, (7) interdisciplinary knowledge for international cooperation activities, (8) knowledge about own project, and (9) knowledge on theories of international cooperation. Required Competences for Development of International Collaborative Tasks consisted of thirty components which were divided into four phases (personal competences, preparation and planning phase, implementation phase, and after project.) Based on the result of this survey the investigators designed the international nursing graduate program. The program has started from the academic year of 2005 at the investigators' college. The progress of students' learning and outcomes of these educational programs should be monitored using formative evaluation.

Objective: It is important to prevent dispensing errors for the safety of patients.  For this purpose, it is necessary to improve the dispensing process on the basis of risk priority.  Quantitative evaluation of risk in each operation makes it possible to compare the risk relatively.  In this study, we analyzed data reported in the Pharmacy Risk Error Management System (PREM-S) to evaluate the risk priority in the medicine preparation step of the dispensing process.
Methods: Data of 1,202 cases concerning medicine preparation step were extracted from in 2,458 cases reported into PREM-S between May 2010 and April 2011.  We classified the medicine preparation step into 31 categories based on the operation.  We analyzed the levels in each category as adverse effects on patient’s health by the errors and also the relationship between adverse effect and detection time.  The level represents the degree of adverse effect for the patient.
Results: Information on levels of the 31 categories was obtained from the analysis.  Eight categories included reports of effects on the health of patients.  Three categories such as calculation of powder medicine included level 4 cases.  Detection time was significantly different between level 1 and levels 2 to 4, but there was no significant difference between levels 2 to 4.
Conclusion: The results suggest that analysis of data reported in PREM-S enables evaluation of the risk priority systematically and efficiently.  Evaluation of the risk priority will contribute to prevention of dispensing errors and health effects derived from them.

  An inquiry was made into the health of 10 one-time asbestos workers now living in the southern part of Akita Prefecture who had taken screening tests for asbestosis on a regular basis. The purpose of this study was to provide pertinent information and better health support to these people at high risk of developing asbestos-related diseases. The average number of years they served as asbestos workers was 11.1±2.12 years and 29.8±4.64 years had passed sincefirst exposure. All the subjects were found to have had no idea about guarding against exposure to asbestos while at work. Neither had they been told to protect themselves from this fibrous mineral by their employers. What motivated them to take examinations for asbestosis was news reports provided by newspapers and other mass media about pulmonary disorders caused by earlier contact with asbestos fibers. Half of the subjects did not know anything about qualifications for receiving the health card for retired asbestos workers. They expressed apprehensions about their health. One subject said, “I may be taken ill anytime,” another said, “The psychological burden of always taking meticulous care of my health is overwhelming,” and still another said, “There is no way of knowing whether I am suffering from asbestosis because there is no symptom.” The latest statistics showed that the number of officially acknowledged victims of asbestos-related pulmonary diseases is increasing across the nation together with the incidence of mesothelioma. To allay the anxiety of former asbestos workers about their health, this study suggested that as the responsibilities of the medical profession, we should (1) get acquainted with the relief system and related laws, (2) help the patients maintain their quality of life by following up the their problems over a long period of time, and (3) continue research activities and make the results public so as to contribute to the relief of the patients.

A 43-year-old man visited another hospital because of dry cough and dyspnea in a supine position after having experienced chest pain about 1 month prior to his visit. He had undergone open aortic commissurotomy and ligation of the ductus arteriosus due to congenital bicuspid valve aortic stenosis and patent ductus arteriosus at age 13. CT scan showed a dissected giant aortic aneurysm (12.0cm in diameter) of the DeBakey Type II which compressed surrounding organs, such as his trachea, bilateral main bronchus, superior vena cava, and right main pulmonary artery. Echocardiograms revealed severe aortic stenosis and a dissecting ascending aortic aneurysm. The patient was admitted to our hospital and an urgent operation was performed. Under cardiopulmonary bypass with selective cerebral perfusion, a replacement of the aortic root and the ascending-arch aorta with the inclusion technique was performed. Postoperatively, the patient suffered from ventilatory disturbance under mechanical ventilation. CT scan showed a giant aneurysmal sac containing a hematoma in the perigraft space and the false lumen of the aneurysmal wall and remaining tracheobronchial compression. A reoperation was performed for removal of the hematoma and placation of the aneurysmal sac. The subsequent postoperative course was good. The patient was weaned from mechanical ventilation at 12 days and discharged at 67 days after the initial operation. Histologically, the resected aortic wall showed cystic medial necrosis.

In Palliative care, we meet patients with easy-bleeding superficial malignant tumors, such as head and neck cancer, skin metastasis of all kinds of cancer and unresectable breast cancer. But it is not easy to control bleeding even though we use various means, and many doctors have difficulties in stopping bleeding. We report a case with a recurrent tumor of pharyngeal cancer that showed easy-bleeding and discharged massive exudates. Although she received several alcohol local injections because of bleeding of the tumor, she needed a dressing change over 5 times in a day. It made her QOL worse. In this case, we used Mohs paste and after using it, the surface had been fixed and dried up, resulting in a decrease in bleeding, exudate, frequency of dressing change and bad odor. Mohs paste was made of distilled water, zinc chloride, zinc starch and Glycerol. Zinc chloride changes to zinc ion by water in the wound and makes protein cohere and thereafter tissues, vessels and cell membrane of bacteria are fixed chemically. We could stop bleeding for 15 days with only 20 minutes contact with Mohs paste, and massive exudates and bad odor decreased. Mohs paste, which is made in your hospital pharmacy with cheap materials, can be used for bleeding or massive exudates repeatedly if there is not a thick blood vessel anatomically under the tumor. It was effective to improve her QOL. Palliat Care Res 2009; 4(2): 346-350

Coix lacryma-jobi L. var. ma-yuen Stapf is a grass long been used in traditional medicine as a nourishing food and reported to possess pharmacological effects including anti-tumor, anti-obesity, anti-diabetic, etc. In order to evaluate the possible mutagenicity of the hot water extract of all parts (husks, pellicles, and astringent skin) of the food, we performed a reverse mutation test in bacteria, a mouse lymphoma assay and a mouse micronucleus test. The results of all tests were negative. It was concluded that the extract has no mutagenicity for living bodies.
