We report a case of a chronic contained rupture of abdominal aortic aneurysm associated with spinal caries. A giant retroperitoneal mass with bony destruction of the anterior bodies of thoracic and lumber vertebrae was detected on computed tomography in a 72-year-old woman. The patient was asymptomatic but had a history of spinal tuberculosis complicated with cold abcess 44 years earlier. Magnetic resonance imaging suggested the presence of a paravertebral retroperitoneal abscess or organized hematoma. Surgery was performed through median laparotomy and an aortotomy revealed a punched-out defect, 17mm×17mm in size, in the posterior wall of the abdominal aorta, and the large cavity of an aneurysm with an organized thrombus was observed through the defect. The abdominal aorta and common iliac arteries were replaced with a bifurcated graft. The punched-out defect was closed with the anterior wall of the aorta for the purpose of isolating the prosthesis from the aneurysm. The postoperative course was uneventful and there were no signs of prolonged inflammatory reactions. In this case, it was considered that chronic contained rupture of the abdominal aortic aneurysm resulted from spinal tuberculous osteomyelitis eroding into the aorta.

To evaluate the effects of acupuncture on the immune system, the leukocyte, monocytes, lymphocyte and lymphocyte surface markers, CD2, CD4, CD8, CD11b, CD16, CD19 and CD56 in the peripheral blood of seventeen healthy volunteers were counted. The leukocyte above CD+ cell counts significantly increased after acupuncture. The results indicate that acupuncture may regulate the immune system and can increase the activity of cellular and humoral immunity and NK cell.
According to the percentage of lymphocytes or granulocytes, volunteers were divided into two types, those with more than 70% of granulocyte were recognized as G type and those with more than 40% of lymphocyte were divided into L type. Interestingly, before and after the treatment of acupuncture, the number of granulocytes and lymphocytes had a negative relationships. Namely we found an increase in the lymphocytes as well as a decrease in the granulocytes in the G type. On the other hand in the L type, we found an increase in the granulocytes and a decrease in the lymphocytes. Therefore we suggest that acupuncture can enhance the activity that maintains the balance of the immune function.

A main symptom of chronic fatigue syndrome (CFS) is fatigue which continues for more than 6 months and does not improve with rest, leading to a marked decrease in quality of life. Other problems include fever, sleep disorder, and headache. Etiologically, a preceding viral infection, immunological disorder, and changes in the central nervous system, especially in hippocampus have been reported. However, the precise pathogenesis of CFS has not been elucidated, and neither diagnostic markers nor effective treatments have yet to be discovered. Here, we report a case of CFS, successfully treated with Kampo medicines.
The patient was a 16-year-old high school student, who had received medical therapy for one year under the diagnosis of CFS. His chief complaint was a continuing fever and strong malaise after influenza infection. At his visit to our outpatient clinic, we confirmed that his symptoms met the criteria for CFS. A combination treatment with Kampo medicine (sanoshashinto) and duloxetine improved his malaise and fatigue in 4 weeks, but fever and anorexia remained. The addition of hochuekkito to the combination dramatically ameliorated his symptoms. This case suggests that Kampo medicines would contribute to the effective treatment of CFS, which is refractory to Western medicines.

Background:
Few studies have examined the performance of the public long-term care insurance (LTCI) from the perspective of geographic equity. This study investigated regional variations and associated factors in the supply and utilization of nursing home care within and also between Japan and Korea.
Methods:
A comparative dataset was developed by extracting data from 2013–2015 LTCI statistics yearbooks and Organization for Economic Cooperation and Development regional statistics, as well as other comparable data in Japan and Korea. The unit of analysis was the prefecture in Japan and the province in Korea. We computed variation indices and conducted regression analyses for regional variations within each country and decomposition analyses to examine the variations between the countries.
Results:
The overall regional supply and use of nursing home care were higher in Japan, but the regional variations in Korea were larger than in Japan. In both countries, the nursing home supply was negatively associated with the proportion of older people with independent living. Nursing home use was also negatively associated with the supply of hospital beds and home care agencies in Korea; the relationship was the opposite in Japan, however. The country-based differences were more likely to be explained by differences in the distributions of the variables included in the analytical model than country-specific characteristics.
Conclusion
Regional-level nursing home supply and use were unequal in both countries, and the contributing factors were not the same. Policy efforts are needed to advance regional equality in long-term care (LTC) and collaboration between health and LTC institutions for frail older people, especially in Korea.

Introduction: Paroxysmal atrial fibrillation (Paf) occurred in an inpatient who has been prescribed methadone for cancer pain in our palliative care unit, but oral administration of aprindine (antiarrhythmic agent) succeeded in defibrillation and methadone administration could be continued. Case: A 75-year-old man had developed multiple bone metastases after resection of thyroid cancer. Due to refractory cancer pain, switching from oxycodone to methadone was performed. Pain relief was achieved with methadone 40 mg/day and without QT interval prolongation. After methadone administration about 9 months, there suddenly became loss of appetite in the morning of one day. ECG examination revealed Paf onset. Aprindine 20 mg was orally administered for the purpose of defibrillation. After about 2 hours sinus rhythm was gained and later without recurrence. Conclusion: This case was considered to have the coincidental complication of paroxysmal atrial fibrillation in the course of methadone administration. If administration of antiarrhythmic agents is performed in a patient whom has been prescribed methadone, it is feared to lead to result in QT interval prolongation due to drug interactions. It is important to carefully select an agent that rarely leads to QT prolongation.

BACKGROUNDChina has achieved universal health insurance coverage. This study examined how patients and hospitals react to the different designs of the plans and to monitoring of patients by the local authority in the Chinese multiple health security schemes.
METHODSThe sample for analysis consisted of 1006 orthopedic inpatients who were admitted between January and December 2011 at a tertiary teaching hospital located in Beijing. We conducted general linear regression analyses to investigate whether medical expenditure and length of stay differed according to the different incentives.
RESULTSPatients under plans with lower copayment rates consumed significantly more medication compared with those under plans with higher copayment rates. Under plans with an annual ceiling for insurance coverage, patients spent significantly more in the second half of the year than in the first half of the year. The length of stay was shorter among patients when there were government monitoring and a penalty to the hospital service provider.
CONCLUSIONSOur results indicate that the different designs and monitoring of the health security systems in China cause opportunistic behavior by patients and providers. Reformation is necessary to reduce those incentives, and improve equity and efficiency in healthcare use.

BACKGROUND:
There is substantial evidence on the association between lower education and unhealthy behaviors. However, the mechanism underlying this association remains unclear. This study aimed to examine whether income, health literacy, and social support mediate the association between education and health-related behaviors.
METHODS:
A questionnaire survey was conducted in metropolitan areas in Japan from 2010 to 2011 among residents aged 25-50 years. Data from 3663 participants were used in this study. Health literacy was measured using the Communicative and Critical Health Literacy scale. Health-related behaviors were current smoking, poor dietary habits, hazardous drinking, and lack of exercise. Poisson regression analyses with robust variance estimators were conducted to examine the associations between education and these health-related behaviors. Multiple mediation analyses were conducted to estimate the magnitudes of the mediating effects of income, health literacy, and social support on these associations.
RESULTS:
Less educated participants had higher risks of all unhealthy behaviors. Income mediated the associations of education with smoking (6.4%) and exercise (20.0%). Health literacy mediated the associations of education with dietary habits (15.4%) and exercise (16.1%). Social support mediated the associations of education with dietary habits (6.4%) and exercise (7.6%). The education-drinking association was mediated by income in the opposite direction (-10.0%). The proportions of the total effects mediated by income, health literacy, and social support were 9.8% for smoking, 24.0% for dietary habits, -3.0% for drinking, and 43.7% for exercise.
CONCLUSIONS
These findings may provide clues for designing effective interventions to reduce educational inequalities in health-related behaviors.

BACKGROUND: Although the utility of flaps for the treatment of sternal wound infections following median sternotomy has been reported for 30 years, there have been few reports on the risk factors for complications after reconstruction. The objective of this investigation was to identify factors related to complications after the reconstruction of sternal wound infections. METHODS: A retrospective analysis of 74 patients with reconstructive surgery after sternal wound infection over a 5-year period was performed. Clinical data including age, sex, body mass index (BMI), comorbidities, bacterial culture, previous cardiac surgery, wound depth, mortality rate, type of reconstructive procedure, and complication rate were collected. RESULTS: The patients' BMI ranged from 15.2 to 33.6 kg/m2 (mean, 23.1+/-3.74 kg/m2). Wound closure complications after reconstructive surgery were observed in 36.5% of the cases. The mortality rate was 2.7%. Diabetes mellitus significantly affected the rate of wound closure complications (P=0.041). A significant difference in the number of complications was seen between Staphylococcus aureus (S. aureus) and coagulase-negative Staphylococci (P=0.011). There was a correlation between harvesting of the internal thoracic artery and postoperative complications (P=0.048). The complication rates of the pectoralis major flap, rectus abdominis flap, omentum flap, a combination of pectoralis major flap and rectus abdominis flap, and direct closure were 23.3%, 33.3%, 100%, 37.5%, and 35.7%, respectively. CONCLUSIONS: Diabetes mellitus, S. aureus, harvesting of the internal thoracic artery, and omentum flap were significant factors for complications after reconstruction. The omentum flap volume may be related to the complications associated with the omentum flap transfer in the present study.

BACKGROUND: Cutaneous malignant melanoma has a poor prognosis. The detrimental effect of incisional biopsies on the outcome of malignant melanoma has been debated. The aim of this study was to determine the effect of the presence and type of biopsy on the prognosis of malignant melanoma. METHODS: The medical records of 109 malignant melanoma patients treated at Tokushima University Hospital from 1983 to 2007 were reviewed. After excluding 28 cases with stage 0 disease or incomplete data, 81 cases were analyzed in detail with respect to patient sex, age, tumor site, clinical stage at diagnosis, presence of ulceration or lymph node metastasis, and prognosis. The five-year survival and five-year disease-free survival rates of patients who underwent incisional or excisional biopsies were compared with those who did not undergo a biopsy. RESULTS: The male-to-female ratio was 1:1.19. The mean age was 61.3 years (range, 19-93 years). The most common site was a lower extremity, and the most common clinical stage was stage II. No significant differences in clinicopathological features, five-year survival rates, and five-year disease-free survival rates were observed among the three groups. CONCLUSIONS: The presence and type of biopsy neither affected the metastatic rate nor the prognosis of malignant melanoma. The use of incisional biopsies is not encouraged because tumor thickness cannot be measured accurately. However, they may be helpful for confirming the diagnosis if an excisional biopsy cannot be performed.

OBJECTIVESWith greater concern for efficient resource allocation and profiling of medical care, a case-mix classification was applied for the per-diem payment system in Japan. Many questions remain, one of which is the role of comorbidity and complication (CC) in grouping logic. We examined the association of the number of CC with the length of hospital stay (LOS) and hospital mortality as well as the proportion of LOS high outliers in 19 major diagnostic categories (MDCs).
METHODSThis study was a secondary data analysis embedded in a government research project, including anonymous claims and clinical data during a 4-month period from July 2002. Every 19 MDC, LOS, hospital mortality or proportion of LOS high outliers was compared by the number of CC and presence of any procedures.
RESULTSFrom 82 special function hospitals, 241,268 patients were enrolled in this study. Among all patients, 50.5% were identified without any CCs, 32.4% with one or two, 13.4% with three or four, and 3.7% with over five CCs. The overall mean LOS was 22.15 days and hospital mortality 26.05 cases per 1,000 admissions. In any MDC, LOS and the proportion of outliers increased as the number of CC rose. The mortality rate increased prominently in the respiratory system and the hematology system.
CONCLUSIONSThis study demonstrated that the occurrence of more CC caused longer LOS and higher mortality in some major disease categories. Further study will clarify the association of the weighted CC with resource use through controlling procedures specific for MDC.
