S1-2Waon therapy for ischemic heart disease / 日本温泉気候物理医学会雑誌

<b>Objectives: </b>Waon therapy relieves ischemic symptoms in patients with peripheral arterial disease. Waon therapy increases capillary density and blood flow in ischemic hindlimbs of mice (Circ J 2006;70:463). Moreover, we have shown that Waon therapy increases capillary densities of non-infarcted myocardium of rat with myocardial infarction in association with increases in myocardial expression of eNOS and VEGF mRNA (Am J Physiol Heart Circ Physiol 2011;301:H548).

The severity of ischemia was quantified by thallium-201 myocardial perfusion scintigraphy with adenosine before and after 3-week Waon therapy. Treadmill exercise test, flow-mediated dilation (FMD) of the brachial artery, and the number of circulating CD34-positive bone marrow-derived cells, a putative precursor of endothelial progenitor cells, were determined.

Overexpression of Epstein-Barr virus-induced gene 3 protein (EBI3) in MRL/lpr mice suppresses their lupus nephritis by activating regulatory T cells.

To identify the effect of an imbalance of Th1/Th2 cytokines on the development of autoimmune glomerulonephritis (lupus nephritis), we studied the modification of pathological changes in diffuse proliferative glomerulonephritis (DPGN) and membranous glomerulonephritis (MGN) in MRL/lpr mice, which are animal models of systemic lupus erythematosus (SLE). Transgenic MRL/lpr mice (Tg) that overexpressed Epstein--Barr virus-induced gene 3 (EBI3) showed almost normal renal function, which was demonstrated by healing of glomerulonephritis upon renal histology, as compared to the wild-type MRL/lpr (Wt) mice. The levels of anti-dsDNA antibodies and IgE decreased in the Tg mice compared to Wt mice. Quantitative real-time PCR indicated an increase in the mRNA levels of FoxP3, and a decrease in that of IFNγ in the splenocytes of Tg mice as compared to Wt mice. In addition, flow cytometric analysis showed an increase in CD4(+)CD25(+)FoxP3(+)-T cells in the former, as compared to the latter. Our findings suggest that EBI3-overexpression in MRL/lpr mice induces generation of regulatory T cells, which causes suppression of autoimmune and inflammatory reactions by affecting the Th1/Th2 cytokine balance.

Transesophageal Echocardiographic Findings Are Independent and Relevant Predictors of Ischemic Stroke in Patients with Nonvalvular Atrial Fibrillation

BACKGROUND AND PURPOSE: Not only clinical factors, including the CHADS2 score, but also echocardiographic findings have been reported to be useful for predicting the risk of ischemic stroke in patients with nonvalvular atrial fibrillation (NVAF). However, it remains to be determined which of these factors might be more relevant for evaluation of the risk of stroke in each patient. METHODS: In 490 patients with NVAF who underwent transesophageal echocardiography (TEE), we examined the long-term incidence of ischemic stroke events (mean follow-up time, 5.7+/-3.3 years). For each patient, the predictive values of gender, the CHADS2 risk factors (congestive heart failure, hypertension, age > or =75 years, diabetes mellitus, history of cerebral ischemia), the CHADS2 score, and the findings on echocardiography, including TEE risk markers, were assessed. RESULTS: The ischemic stroke rate was significantly correlated with the CHADS2 score (p or =75 years, history of cerebral ischemia, CHADS2 score > or =2, and presence of TEE risk were significantly correlated with the incidence of ischemic stroke. Cox proportional hazards regression analyses identified age > or =75 years and presence of TEE risk as significant predictors of subsequent ischemic stroke events in patients with NVAF. As compared with that in persons below 75 years of age without TEE risk, the ischemic stroke rate was significantly higher in persons who were > or =75 years of age with TEE risk (4.3 vs. 0.56%/year, adjusted hazard ratio=8.94, p or =75 years with TEE risk.

Predictors of Poor Outcome in Patients with Acute Cerebral Infarction

BACKGROUND AND PURPOSE: Plasma D-dimer levels are elevated during the acute phase of cerebral infarction (CI). We investigated whether the D-dimer level on admission and other clinical characteristics could be used to predict the poor outcome of patients with acute CI. METHODS: The clinical characteristics and plasma D-dimer levels measured within 3 days of onset were compared according to outcome among patients with acute CI. RESULTS: In total, 359 consecutive patients (mean age, 71.8 years) were examined, of which 174 had a poor outcome [score on the modified Rankin scale (mRS) > or =3] at 30 days after hospitalization. The mean mRS score was higher and a poor outcome was observed more frequently among women than among men (p or =75 years), prior history of CI or transient ischemic attack, and elevated D-dimer level (> or =1.0 microg/mL) were significantly higher among patients with a poor outcome than among those with a good outcome. A multivariate analysis showed that elevated D-dimer level [> or =1.0 microg/mL; odds ratio (OR), 2.45; 95% confidence interval (95% CI), 1.52-3.89; p<0.01], advanced age (OR, 1.93; 95% CI, 1.21-3.07; p<0.01), and female gender (OR, 1.75; 95% CI, 1.08-2.83; p=0.02) were independent predictors of a poor outcome. CONCLUSIONS: Certain clinical characteristics (gender and advanced age) and an elevated D-dimer level upon admission can be used to predict the outcome of patients with acute CI at 30 days after hospitalization.

A case of gastric cancer with abdominal pain in whom successful pain control was achieved by opioid rotation to morphine

<b>Introduction</b>: Although fentanyl patch (FP) are often used to treat cancer pain because of the low incidence of adverse effects of this formulation, there are cases in which it is impossible to eliminate the pain despite increasing the doses. We report a patient of advanced gastric cancer with abdominal pain, in whom successful pain control was achieved by opioid rotation from FP to continuous intravenous infusion of morphine hydrochloride. <b>Case Report</b>: The patient was a male in his 60's who had been diagnosed as having primary gastric cancer and complained of abdominal pain, thought to be visceral pain caused by obstruction of the digestive tract. Oral intake became more difficult as the disease progressed. Despite a switch to FP from oxycodone used to treat the abdominal pain and an increase in the dose, pain relief was not achieved. Then, we undertook a partial opioid rotation to continuous intravenous infusion of morphine hydrochloride, which provided adequate pain control. <b>Discussion</b>: One possible reason for the pain relief in this patient is suppression of the gastrointestinal motility by morphine. When adequate pain relief cannot be achieved with one opioid, opioid rotation should be considered. We concluded that the opioid rotation should, however, be performed in a stepwise manner.

Pooling System for Multiple-Choice Questions for the National Examination for Medical Practitioners. Results of a Field Study in Japan / 医学教育

The Ministry of Health and Welfare of Japan is planning a pooling system for multiple-choice questions (MCQs) for the national examination for medical practitioners. To clarify possible problems of such a system, a field study was performed by 10 medical schools in Japan using 90 MCQs from previous examinations. Nine hundred twenty-four 6th-year students participated in the field test. For each MCQ, the correct-response rates at the originating school and those obtained in the field test were significantly correlated. Thus, the correct-response rates to questions on the field test could be predicted from the rates at the originating schools. However, for each question the correct-response rate was significantly higher for students of the originating school than for students of other schools. In the national examination, care should be taken to prevent differences in scores on the basis of question sources.

Association between the Combination Therapy and Underlying Diseases for Hypertensive Patients by a Drug Utilization Survey / 薬剤疫学

Objective : To examine the association between the combination therapy of calcium antagonists with angiotensin converting enzyme (ACE) inhibitors and underlying diseases for hypertensive patients.<BR>Design : Cross-sectional survey of the drug utilization.<BR>Methods : This survey included 603 hypertensive patients who had visited Toyama Medical and Pharmaceutical University Hospital, Toyama, Japan more than twice from January to June in 1996 and received the prescriptions of calcium antagonists and/or ACE inhibitors. Main outcome measure was the combined medication of calcium antagonists with ACE inhibitors. Underlying diseases under consideration were diabetes mellitus (DM), hyperlipidemia (LIPID), ischemic heart disease (IHD), chronic heart failure (CHF), and ischemic stroke (STROKE).<BR>Results : Out of 603 hypertensive patients, 57.5% received only calcium antagonists, 23.7% received only ACE inhibitors, and 18.7% received both of them. Patients with either IHD or CHF tended to receive the combination therapy as compared to DM or LIPID. Although men tended to receive the combination therapy, a gender effect might be a confounder for the association. Logistic regression showed a 33% increase (P=0.265) in frequency of the combination therapy in patients with IHD after adjusting for age and gender.<BR>Conclusion : Some underlying diseases were associated with more frequent prescriptions of the combination therapy for hypertensive patients, especially with ischemic heart diseases. This result should be regarded as an exploratory stage although the pattern of antihypertensive drug use could be reasonably explained from the pharmacological sense.

On Farmer's Lung / 日本農村医学会雑誌

Farmer's lung is a form of hypersensitivity pneumonitis, which is manifested mainly as an occupational disease among dairy farmers exposed to organic dusts from moldy hay and compost in silos and lofts. In Europe and America, it has been known for many years. In Japan, it frequently occurs in Hokkaido, Iwate and Hokuriku districts during winter months from November to March. The culprit antigens are spores of actinomycetes thermophilus such as Micropolyspora faeni and Thermoactinomyces vulgaris. In recent years, various preventive measures have been taken. For instance, in order to prevent hay from heating by fermentation and the thermophile from thriving, farmers desiccate hay as much as possible and keep it in air-tight plastic containers. The result is a notable decrease in the prevalence rate of this ailment. Nonetheless, with graying the rural population, pulmonary fibrosis caused by chronic exposure to low levels of organic dust is posing a grave health problem in the dairy farming communities. As a prophylactic measure against chronic fibrotic lung disease, there is a need to implement a comprehensive heath control program consisting of continual sanitary checkups at workplace and counseling at an early stage in addition to periodic health examinations. Another health threat which has more recently loomed up in the dairy farming communities is environmental pollution.

Preventive health strategies for farm housewives in southern Tokushima prefecture / 日本農村医学会雑誌

The subjects are farm housewives in two different agricultural communities of southern Tokushima Prefecture. Most of them are engaged in mixed farming on hilsides facing south. The climate is mild all the year around.<BR>The people in the two communities, like others in the district, undergo medical checkups regularly executed under the outreach health program of our hospital.<BR>In order to obtain data related to their way of living and working conditions, a questionnaire was conducted. In a similar way, a survey was carried out to measure the change in the attitude of the subjects toward health care after medical examination and consultation.<BR>In Community A, the economy is largely based on orange growing in vinyl-covered hothouses and bamboo shoots. Of the housewives who responded to our survey, 87.3% said their livelihood depends chiefly on agriculture.<BR>Working hours were longest among those in their 40s, 26.8% of whom were found suffering from anemia, in the latest health checkup.<BR>Lower levels of neutral fat and a lower degree of albuminurea were noted among those aged 40 or under. These findings suggest that health promotion measures be taken from the standpoint of nutrition.<BR>The latest health checkup also revealed that the health conditions remained poor among those who had given little thought to the results found in the previous group medical examination.<BR>In Community B, agriculture is dominated by paddy rice and orange growing. But the community is suburban.<BR>In formulating a health control program for women in Community B, emphasis should be placed on prevention of hypertension, obesity and other conditions associated with the adult disease.
