The most common method of evaluating beneficial impacts of environmental policies is cost-benefit analysis (CBA). In the present review, CBA methods for air pollution impacts are reviewed. Three types of air pollution effects are identified, including health, productivity, and amenity. Market valuation, stated preference methods, and revealed preference methods are identified for valuing benefits. Three types of costs are described, including private sector costs, societal costs, and governmental regulatory costs. A benefits valuation approach based on Freeman’s principals is described. A costs valuation approach based on U.S. Environmental Protection Agency and Dixon et al. principals is described. Limitations associated with estimates of benefits and costs are summarized. Input assumptions and results are compared for several existing air pollution control analyses. The importance of CBA in environmental policy studies is discussed. Our conceptual approaches should be useful in analyses of urban air pollution impacts and air pollution prevention policies.

A 13-year-old girl was admitted to our hospital with a history of syncope after exercise. Neither left ventricular (LV) function nor hypertrophy was detected by transthoracic echocardiography. However, 24-h Holter electrocardiogram demonstrated ST segment depression with increasing heartbeat. Exercise ²⁰¹Tl myocardial scintigram also demonstrated ischemia of the anterior LV wall. Multi-slice coronary computed tomography (CT) demonstrated hypoplasia of the left main coronary artery. The syncope on exertion was ascribed to myocardial ischemia due to hypoplasia of the left main coronary artery. We performed off-pump coronary artery bypass graft (CABG) (left internal thoracic artery-left descending artery). The postoperative course was uneventful and postoperative stress ²⁰¹Tl myocardial scintigram demonstrated the absence of myocardial ischemia. Coronary CT demonstrated good graft patency. To date, there has not been any recurrence of syncope on exertion. We herein report a successful off-pump CABG for a patient with syncope due to hypoplasia of the left main coronary artery. Syncope on exertion due to hypoplasia of the left main coronary artery is very rare. However, certain forms of congenital coronary anomalies are associated with adverse cardiac events, including sudden cardiac death. The diagnosis, therefore, can be important and CABG is indicated, especially when there is repetitive syncope due to myocardial ischemia.

The objective of this study is to assess the differences in access to antiretroviral treatment among health insurance recipients, using a patient-based analysis.
METHODS: The subjects were 324 outpatients with the human immunodeficiency virus who were treated at a regional hospital for infectious diseases in Khon Kaen Province. We collected data every visit of the patients during the study period between April1 and September 30 in 2002. We defined access to antiretroviral treatment as having a prescription for antiretroviral drugs on at least one visit during the study period. We examined the relationship between access to antiretroviral treatment and age, sex, stage of acquired immune deficiency syndrome (AIDS), and health insurance. We also compared the results of the patient-based analysis and the record-based analysis that was used in our previous study.
RESULTS: Multiple logistic regression analysis shows that patients insured by the Civil Servant Medical Benefit Scheme have better access to antiretroviral treatment than the others (vs. Universal Coverage; odds ratio=11.38, 95% confidence interval=4.09, 31.65). We have also shown that patients with AIDS-related complex have better access to antiretroviral treatment compared to asymptomatic AIDS patients (odds ratio=3.38, 95% confidence interval=1.31-8.76). Values of these odds ratios were lower in the record-based analysis than in the patient-based analysis.
CONCLUSIONS: Patients insured by the Civil Servant Medical Benefit Scheme had better access to antiretroviral drugs. We reconfirm the differences in access to antiretroviral treatment among health insurance recipients, using the patient-based analysis.

Objective
 To investigate the relationship between uses of highly active antiretroviral therapy (HAART) and sexual behavior among people living with HIV (PLHIV) in northeast Thailand.
Methods
 Data were collected both by interviews using a structured questionnaire and by a self-administered questionnairewith HIV positive patients who made an outpatient visit to a public hospital in northeast Thailand between March2004 and January 2005. Fisher's exact test and multiple logistic regression analysis were conducted to identify thefactors associated with regular condom use when these patients had sex with their spouse/partner.
Results
 Among 289 patients (146 with HAART and 143 without HAART) who participated in the study, 122 had sex with their spouse/partner in the three months before the survey. Among them, 70 used a condom every time, 17 used a condom sometimes, 32 never, and 3 unknown. Excluding the 6 patients who did not answer all of the questions, 116 patients remained in the analysis. In the multiple logistic regression analysis, sex, education, employment, years since HIV infection, illness episode in the past one month, and use of HAART were entered as the explanatory factors. Use of HAART (odds ratio=9.8, 95% CI: 2.9 - 32.9) and current employment (odds ratio= 5.2, 95%CI: 1.3 - 20.9) were significantly associated with regular condom use.
Conclusion
 Use of HAART was positively associated with use of condoms when PLHIV had sex with their spouse or partner.

Purpose：This study investigated the current state of medical care and home palliative care for terminally ill cancer patients in Japan. Methods：We conducted a retrospective questionnaire study of 352 cancer patients who received home palliative care from 6 specialized home care clinics and discontinued home care or died from January to June in 2012. Results：The questionnaire was answered by 290 patients〔165 men（57％）, mean age：72±13 years〕who started home palliative care after completing cancer treatment. Home visits from nurses were used by 238 patients（98％）and 95 patients（39％）used home care workers. Within a month before discontinuation of home care or death, 72 patients（30％）received fluid therapy and 127 patients（52％）received strong opioids. The outcome of home palliative care was death at home in 242 patients（83％）and discontinuation of home care in 48 patients（17％）. The reason for discontinuation was family physical and mental problems or physical problems of the patient. Conclusion：This study demonstrated the current state of home palliative care by specialized home care clinics.

Objectives:To determine the factors influencing death or the cessation of palliative care in home-based setting among patients with cancer. Methods:We included 352 terminally ill patients with cancer who received home-based palliative care from six specialized palliative care clinics. We reviewed the medical charts when patients died at home or chose to stop home care. Results:A total of 82％ of participants died at home, and 18％ chose to stop home care. Multiple logistic regression analysis revealed five independent factors that affected cessation of home-based palliative care:patient and informal caregiver preferences for the place of death not to be at home［odds ratio, 10.1（95％ Confidential interval, 2.5-40.9）and 51.9（11.9-226.6）, respectively］or uncertain preferences［5.0（1.3-19.4）, 10.8（2.3-50.5）］;anxiety and depression among informal caregiver［4.1（1.2-13.9）］;lower frequency of informal care［6.8（2.0-23.4）］;and history of admittance to hospital during home care［11.6（4.0-33.9）］. Conclusion:We revealed independent factors influencing death or the cessation of palliative care in home-based settings among patients with cancer. Our findings suggest the importance of providing support for decision making about the place of death and hospital admission, and psychosocial support for informal caregiver to ensure home death consistent with patient preference.

Surgical interventions for aorto-iliac obstructive diseases were studied through the operative results. Eighteen patients underwent aorto-femeral bypass (AOF) and 23 who were over 70 years of age or who had serious preoperative complications had axillofemoral bypass (AXF). No perioperative death occurred in AOF patients, while the mortality rate of AXF patients was 8%. Postoperative ankle pressure indexes were significantly higher in AOF patients than in AXF patients. Follow-up graft patency rate was 100% in AOF patients at 54 months (mean), and 85% in AXF patients at 44 months respectively. AOF should be the first choice for patients with aorto-iliac obstructive disease, and AXF is suitable only for high-risk patients.

In a consecutive series of abdominal aortic aneurysm repairs, a non-washing autotransfusion unit system was used in 47 patients, and was not used in 25. In the 47 patients treated with the autotransfusion unit, the average amount of autotransfused blood was 1, 109±131ml in elective cases. The amount of banked blood transfusion was significantly smaller in autotransfused patients (mean; 712ml), compared to non-autotransfused patients (mean; 1, 405ml). Postoperative levels of serum bilirubin were higher in patients with greater autotransfused blood volumes than those with smaller volumes. The combination of preoperative autologous blood donation (2-3 units) and intraoperative autotransfusion is necessary to perform abdominal aortic aneurysm repair without homologous blood transfusion.

A non-anastomotic false aneurysm occurred in a 77-year-old male 11 years after bypass grafting between the left external iliac artery and the right femoral artery using a Cooley double velour knitted Dacron graft. The false aneurysm was caused by rupture of an artificial graft. A partial resection of the graft and its replacement using a Hemashield^® graft were successfully performed. It was speculated that the mechanical stress by the inguinal band degenerated graft fibers and developed aneurysmal formation.

OBJECTIVES: This study aimed to identify factors associated with initiation and adherence of osteoporosis medication from a patient perspective. METHODS: A web-based survey was developed based on health behavior theories. Descriptive analyses were conducted for all survey items. Analyses in a structural equation modeling framework were conducted to identify factors associated with treatment initiation and adherence. RESULTS: Five hundred forty-five women completed the questionnaire. A majority were currently receiving medications for osteoporosis (n = 376, 69.0%) and 25.0% of these patients (n = 94) were considered adherent to their treatment. Knowledge was strongly associated with osteoporosis treatment initiation (standard error [SE], 0.58). Greater knowledge of disease was associated with increased likelihood of initiating medication. Medication complexity (SE, 0.49) and perceived susceptibility to fracture and loss of independence (SE, −0.37) were also associated with initiation. Perceived barriers (SE, −0.85) such as inconvenience, lack of efficacy and financial burden were observed to be the greatest obstacle to adherence. The greater the perceived barriers, the less likely patients were to adhere to medication. Patients' perception of self-efficacy (SE, 0.37) also affected adherence. The greater the patient perception of ability to independently manage their medication, the more likely they were to adhere to the medication. CONCLUSIONS: Different factors were found to be associated with initiation and adherence of osteoporosis medication. Patient knowledge of their disease and the perception of barriers were found to be the most influential. Empowering patients with the knowledge to better understand their disease and decreasing the perception of barriers through education initiatives may be effective in improving patient outcomes.
