Introduction: This study used a meta-analysis to investigate factors related to dizziness/vertigo and their effect size in community-dwelling elderly people.Methods: The search terms "elderly," "dizzy," "community dwelling," and others were used, and a database search was conducted using Ichushi Web and PubMed.Result: In total, 10 studies were extracted. Meta-analysis calculated 28 items as significantly related factors: anxiety, fatigue, taking nitric acid drugs, taking anxiolytics, low self-rated health, memory impairment, depression, sleep disorder, dementia, cancer, balance failure, gait disturbance, physical dysfunction, taking diuretics, living alone, heart disease, fall history, rheumatoid arthritis, stroke, taking sleeping pills, taking multiple drugs, visual impairment, female, ADL impairment, osteoporosis, taking antihypertensive drugs, hypertension, and low education level.Conclusion: The above items may be key variables for investigating dizziness/vertigo in the future.

We report a case of cholesterol crystal embolism (CCE) after endovascular aortic repair for abdominal aortic aneurysm (AAA). A 68-year-old man with AAA underwent endovascular aortic repair. He complained of left lower abdominal pain after the operation. Abdominal CT showed renal infarction on postoperative day 10. Renal dysfunction developed after postoperative day 17. A biopsy of the renal infarct lesion demonstrated characteristic cholesterol clefts in the small arteries. We diagnosed CCE. Steroid therapy was administered and the patient's condition improved remarkably. Diagnosis of CCE is difficult and its prognosis still remains poor. Therefore, we should keep this unusual complication in mind.

Immunoglobulin G4 (IgG4)-related disease can occur in various organs, most of which comprise glandular or ductal tissue. We report a case of IgG4-related disease which occurred in a cardiovascular lesion. A 69-year-old man was found to have a tumorous lesion around the coronary artery. Open chest biopsy showed the diffuse lymphoplasmacytic infiltration, occasional eosinophils and numerous IgG4-positive plasma cells within the lesions. The serum concentration of IgG4 in the postoperative period was 1,080 mg/dl (reference range, <135). We diagnosed IgG4-related periarteritis manifesting as a tumor around the coronary artery. This case suggests that IgG4-related disease can occur around the coronary artery and manifest as a periarterial mass lesion.

OBJECTIVES: This study aimed to investigate differences in physical function by bone mass category as assessed by speed of sound, and the association between bone mass and physical function in Japanese elderly women. METHODS: Participants (≥65 years, n = 954) were divided into the osteoporosis, osteopenia, and normal groups based on speed of sound values, and physical function parameters were compared among groups. In addition, the predictive ability of physical function for low bone mass was determined by area under the curve analysis. Data were collected in 4 cities in Nara, Japan, in 2007 or 2008. RESULTS: All physical functions were significantly lower in the osteoporotic group than in the normal group. Lower bone mass was associated with poor muscle strength and physical function after adjusting for age, height and weight. In addition, one-leg standing time and 10-m gait time were predictive of low bone mass (osteopenia and osteoporosis levels, respectively). Elderly women with low physical function, especially those with a short one-leg standing time, should be suspected of having decreased bone mass. CONCLUSIONS: Measurements of physical function can effectively identify elderly women with low bone mass at an early stage without the need for bone mass measurements. In particular, one-leg standing time and 10-m gait time were good predictors of low bone mass, and is easy to measure, low-cost, and can be self-measured. These findings will be helpful in the prevention and treatment of osteoporosis.

This study examined the effectiveness of a communication program in undergraduate medical education in improving communication in physicians' clinical practice. The effectiveness of the program was assessed with a mail survey using self-rated questionnaires 9 years later. Ninety participants were follwed up in late 1994; 57.8% of them replied to the questionnaire. Of the respondents, 60% replied that programs concerned with active listening and role-playing had benefits on communicating with patients and families. In addition, 40% of respondents answered that case studies aimed at teaching comprehensive medicine with the team approach was effective in improving communication with co-medical staff. These results suggest that the communication program in undergraduate medical education is effective in improving clinical communication in clinical practice when students are highly motivated.

OBJECTIVESTo verify whether the concentrations of arsenic (As) and its compounds in the air (referred to here as arsenic concentrations) affect the standardized mortality ratio (SMR) associated with lung cancer.

METHODSUsing monitoring survey data on arsenic concentrations published by the Ministry of the Environment, we classified the municipalities for which arsenic concentrations were measured (measured municipalities) into ten groups according to the average arsenic concentration. We then determined the SMR of lung cancer, stomach cancer, pneumonia, cerebrovascular disease and cardiac disease for each group using socio-demographic data, such as the national census and demographic trends. The relationships between these factors were compared and investigated by statistical means.

RESULTSNo effect of arsenic concentrations on stomach cancer, cerebrovascular disease or cardiac disease was observed, and while significant differences in pneumonia were observed among several of the male subjects, there were no significant effects of arsenic concentration. However, lung cancer and arsenic concentration showed a significantly positive correlation for both males and females (males: Spearman r = 0.709, P < 0.05; females: Spearman r = 0.758, P < 0.05). The probability of type alpha error was less than 5% in areas with more than 1.77 ng As/m(3) (71st percentile) and less than 1% in areas with more than 2.70 ng As/m(3) (91st percentile). These results confirm that the SMR of lung cancer tends to be higher than the national average in areas of higher arsenic concentrations.

CONCLUSIONSThe SMR of lung cancer is significantly higher in areas with arsenic concentrations of 1.77 ng/m(3) or more.

Introduction: Number of palliative care team increase every year, but the quality of team might differ from each other. We developed “Self-Check Program for Palliative Care Team” to assess and improve the quality of palliative care team. We report the result of the multi-center study to assess the feasibility of this program. Methods: We underwent the “Self-Check Program” as a trial at seven hospitals in Japan in February 2016. We took a questionnaire survey to team leaders and participants to assess the feasibility of this program. Results: Fifty-two medical staffs in six hospitals accomplished this program. Time scheduling and the integration of opinions from each team members were the difficulties came up from questionnaire survey. All team leaders and 87.8% of the participants answered that this program was effective to extract and improve the problem of the team. Also 83.3% of the team leaders were satisfied with the process of planning. Conclusion: Despite some difficulties, majority of the participants considering useful, this program is considered feasible.
