We report a case of chronic mesenteric ischemia associated with severe aortic valve regurgitation and stenosis (ASR). The patient was a 76-year-old man who had been given a diagnosis of ASR in his 40s. He gradually developed heart failure and chronic kidney disorder due to deterioration of ASR. He had started hemodialysis 1 year before admission and had complained of abdominal pain after meals and weight loss during that period. He was admitted to the Department of Cardiology in our hospital for evaluation of ASR. Severe ASR with low output syndrome (C. I. 2.00 L/min/m2) were confirmed by cardiac catheter examination. In addition, abdominal angiography revealed total occlusion of the superior mesenteric artery (SMA) and severe stenosis of the celiac artery (CA). We considered that low cardiac output due to severe ASR had exacerbated the mesenteric ischemia. We performed AVR and abdominal aorta-SMA bypass at the same time to prevent acute mesenteric ischemia in the perioperative period. The combination of valvular disease and CMI is very rare. This is the first report in Japan of simultaneous valve replacement and mesenteric artery revascularization.

Objective: The objective of this study was to clarify issues in providing more effective guidance in the drug treatment, especially the usage instructions of inhaled steroids, of adult bronchial asthma patients by verifying which points of explanation are especially important in controlling attacks, and whether or not issues exist stemming from a evaluation gap between patients and pharmacists regarding the degree of explanation and understanding on the usage instructions of inhaled steroids.
Method: Our survey targeted pharmacists working at community pharmacies in eight different areas of Japan, along with adult bronchial asthma patients using these pharmacies. Patients were questioned regarding the content and the degree of explanation in inhalation methods, the degree of understanding, and the degree of improvement in symptoms. For each point of explanation, the ratio of the score gap between (1) the patients’ evaluation (‘perception’) of the degree of the pharmacists’ explanation and pharmacists’ own evaluation of the degree of his/her own explanation, and (2) the patients’ evaluation of the degree of their own understanding and the pharmacists’ evaluation of the degree of patient understanding was calculated. We also verified the relationship between the patients’ evaluation and the degree of control of asthma attacks using a χ² test. We then reviewed the points of explanation which indicated significant difference, in an attempt to elucidate the characteristics of the patient-pharmacist “evaluation gap.”
Results: The results indicated that the degree of explanation of the “objectives of using inhaled steroids,” and “how to cope with asthma attacks,” as well as the degree of understanding of the “objectives of using inhaled steroids,” “directions for use and dosage,” and “drug interactions” provided an important clue to controlling asthma attacks. Of special note was the existence of “a gap in evaluation (perception)” regarding the degree of explanation and understanding between the patients and the pharmacists for the “objectives of using inhaled steroids” and “how to cope with asthma attacks.”
Conclusions: It is crucial to pay special attention to the objectives of using inhaled steroids and how to cope with asthma attacks when guiding patients.

Objective: This study quantitatively analyzes the factors causing dispensing errors in community pharmacies and explores the characteristics of these factors and their order of importance.
Design and Methods: We collected data records on the contents and causes of dispensing errors as reported between April and July 2009 by a total of 320 pharmacists at 56 stores of two pharmacy chains (15 stores in Hokkaido and 41 stores in the Kansai area). We focused on the following three types of dispensing error: 1) “measurement error”, 2) “wrong drug dispensing error” and 3) “wrong dosage form specification error”. We conducted multiple regression analyses and discriminant analyses with occurrence frequency of each type of error as dependent variables and count frequency of each causal factor as independent variables.
Results: The result of the multiple regression analyses indicated that the primary causes of the three types of errors in order of strength of the regression coefficients were as follows. For “measurement error”: 1) pharmacist’s wrong assumption and 2) calculation error; for “wrong dosage form specification error”: 1) insufficient confirmation of prescription and 2) pharmacist’s wrong assumption; for “wrong drug dispensing error”: 1) pharmacist’s wrong assumption and 2) insufficient confirmation of prescription. The results of the discriminant analysis indicated that only for the discriminant coefficient between “wrong dosage form specification error” and “wrong drug dispensing error” no significant difference in the mean was found (p=0.539).
Conclusions: Results show that partly different factors cause “measurement error” as compared with the two other types of dispensing errors. In addition, while basically the same factors were found to cause “wrong drug dispensing error” and “wrong dosage form specification error,” there was a difference in the order of importance of these factors. This study uncovered differences in terms of causal factors affecting each dispensing error type.

OBJECTIVE: We conducted a pooled analysis of published studies to compare the performance of human papillomavirus (HPV) testing and cytology in detecting residual or recurrent diseases after treatment for cervical intraepithelial neoplasia grade 2 or 3 (CIN 2/3). METHODS: Source articles presenting data on posttreatment HPV testing were identified from the National Library of Medicine (PubMed) database. We included 5,319 cases from 33 articles published between 1996 and 2013. RESULTS: The pooled sensitivity of high-risk HPV testing (0.92; 95% confidence interval [CI], 0.90 to 0.94) for detecting posttreatment CIN 2 or worse (CIN 2+) was much higher than that of cytology (0.76; 95% CI, 0.71 to 0.80). Co-testing of HPV testing and cytology maximized the sensitivity (0.93; 95% CI, 0.87 to 0.96), while HPV genotyping (detection of the same genotype between pre- and posttreatments) did not improve the sensitivity (0.89; 95% CI, 0.82 to 0.94) compared with high-risk HPV testing alone. The specificity of high-risk HPV testing (0.83; 95% CI, 0.82 to 0.84) was similar to that of cytology (0.85; 95% CI, 0.84 to 0.87) and HPV genotyping (0.83; 95% CI, 0.81 to 0.85), while co-testing had reduced specificity (0.76; 95% CI, 0.75 to 0.78). For women with positive surgical margins, high-risk HPV testing provided remarkable risk discrimination between test-positives and test-negatives (absolute risk of residual CIN 2+ 74.4% [95% CI, 64.0 to 82.6] vs. 0.8% [95% CI, 0.15 to 4.6]; p<0.001). CONCLUSION: Our findings recommend the addition of high-risk HPV testing, either alone or in conjunction with cytology, to posttreatment surveillance strategies. HPV testing can identify populations at greatest risk of posttreatment CIN 2+ lesions, especially among women with positive section margins.

Objective: In our country, the measure for the spread of the generic has been introduced over several-time as part of the moderation in health care cost plan. However, not having related to an enough spread unlike Europe and America yet is a current state. Then, we investigated from the view point of patients. A detailed examination was performed for the acknowledgment level and attitude toward the generic drug.
Design and Method: The questionnaire survey was performed for the patient who used the community pharmacy for dispensing prescription. The investigation was performed for two weeks (June and July, 2008) at the 50 drugstores in Hokkaido. The patient attribute, source of information, and kind of the taking medicine were examined as a factor to affect decision making for generic drug substitution.
Result: The main results are as follows. The patients who did not know generic drugs accounted 52% of the total and the patients who did not know the words called generic drugs was 16%. This result shows that the degree of the recognition about generic drugs at that time was still low. The information source for the patients who learned generic drugs were articles of the newspaper, a TV program, and advertising with accounted 52% of the total. Also, the patients who prefer generic drugs in the future were 64%. In the relationships between presence of wish for generic drugs and the source of information, the case of from the doctor, was significant (p<0.05) and the case from the pharmacist showed the tendencies of statistical significance (p=0.076).
Conclusion: From the viewpoint of medicine costs restraint in our country, it seems that the pharmacist contributes for the patient’s generic drugs selection expected positively.

We herein report on a case in which we conducted bypass surgery for occlusion of a left axillary artery aneurysm with ischemic symptoms 21 years after the contraction of Kawasaki disease and achieved symptomatic improvement. The case involved a 22-year-old man who had been suffering from Kawasaki disease since the age of one. He had been undergoing antiplatelet therapy for bilateral axillary artery aneurysms by orally taking aspirin for 20 years. He suffered from symptoms of upper limb ischemia 21 years after receiving a diagnosis of peripheral aneurysms and occlusion of a left axillary artery aneurysm upon 3DCTA. We conducted aneurysmotomy, plication, and bypass surgery between the axillary and brachial arteries via the autologous vein. Pathological examination revealed due to the formation of atheroma in the tunica intima and disarrangement of the layer structure in the tunica media : thickening of the tunica media was partially observed. His fatigue upon exertion of his left upper extremity remarkably improved following surgery. Although peripheral aneurysms associated with Kawasaki disease are rare, as seen in this case, peripheral arterial disease remains and progresses even after long periods of time. It is believed necessary to carry out long term follow-up and examine the approaches to therapy including surgery in accordance with the site and degree of the disease.

Introduction
During the course of primary health care activities in Khammouane province of Lao PDR by non- profit organization, international support and partnership for health, an exceedingly high infant mortality rate was recognized in some villages. As thiamine deficiency was strongly suspected for the main cause of the high mortality, the household survey with an emphasis on nutritional aspect and the measurement of thiamine level in the blood of mothers as well as their breast-milk were carried out for the confirmation.
Methods
The survey was conducted at Sibounhouane sub-district (Group 1) with the highest infant mortality and Hatkhamhieng sub-district (Group 2) with the lowest mortality. Fifty families of the two groups, each consisting of randomly selected 25 families with less than one year old infant(s) were interviewed by using prepared questionnaire. The body weight of both mother and infant was measured and blood and milk were taken from the mother.
Results
The ethnic minorities of the group 1 consisted of Lao Lum (44%) and Lao Theung (56%), whereas only Lao Lum in the group 2. The economical indicators and the mother's educational level in the group 1 were inferior to those in the group 2. There was no significant difference in the methods of preparing staple glutinous rice, likely to flux thiamine and intake of thiaminases between the two groups. High infant mortality rate was documented in the group 1 whose clinical symptoms were mostly consistent with those of infantile beriberi. The concentration of thiamine in the blood and milk of mothers in both groups were considerably lower and significant reduction of thiamine level was observed in the group 1 than the group 2. Nevertheless, both groups of those infants tended to be inadequately fed with the foods except for breast-milk during their early infantile phase.
Conclusions
The low concentration of thiamine in the blood and milk of mothers was strongly suggestive that infantile beriberi due to thiamine deficiency was the principal cause of the infant mortality in the study region. We hereby surmise that thiamine deficiency could be extensively prevalent in Lao PDR than the currently studied areas because of their traditional preparing methods of staple dietary rice, postpartum food taboos and intake of thiaminases. For the prevention of infant death due to severe thiamine deficiency, necessary measures including the exchange of information among the institutions concerned, adequate thiamine supplementation and nutritional counseling have to be urgently adopted.

In our hospital the palliative care committee has been held once a month since 2000. In 2007, a total of 1,583 cancer patients were admitted to our hospital orreceived medical care at home. The average length of hospital stay was 24 days. Of the total number of patients, 88.4% was informed that they had cancer. In the latter half of the year it increased to 92.6% because the palliative caretakers gave doctors accurate information on patients' psychology and social background. In October 2007 a questionnaire survey was conducted on those who visited our palliative care section on the occasion of the hospital festival. A total of 46 responded to our survey about the knowledge of palliative care, physician's precise explanation about the illness, image of opioids, desirable place of death and so on. Twenty-eight respondents (60.9%) did not know anything about palliative care. Forty-four (95.7%) wanted precise explanation of cancer. Thirty-four (73.9%) said they had had a night image of opioids after reading the panel. Twenty-eight (60.9%) responded they would rather stay at home until death. We should give healthy people more information about palliative care and opioids.

BACKGROUND: Specific IgE antibodies against the low-molecular-weight carbohydrate antigen that does not bridge IgE molecules on mast cells are not associated with clinical symptoms. Cross reactivity can be determined in allergen-specific IgE detection assays when the carbohydrate structures between pollen allergens and plant derived food allergens are similar; in such cases, false positive results for grain or legume allergens can be reported for pollen allergic patients who are not sensitized to those allergens. This phenomenon arises owing to the presence of cross-reactive carbohydrate determinants (CCDs). OBJECTIVE: This study aimed to assess the impact of CCD interference on the results for pollen allergen-specific IgE antibodies in the general adult population and to perform CCD inhibition tests evaluating the involvement of CCD on samples positive to pollen allergens. METHODS: Serum samples from 322 subjects were tested for IgE antibodies to pollens and CCD. The research subjects were given questionnaires about pollen allergic symptoms to help assess the presence of allergies. Allergen IgE antibodies for Japanese cedar, Japanese cypress, orchard grass, ragweed, MUXF, bromelain, horseradish peroxidase (HRP), and ascorbate oxidase (ASOD) were analyzed. RESULTS: It was observed that among individuals who tested positive to any of the pollen allergens, the positive ratio of CCD-specific IgE antibody was the highest for HRP (13.5%–50.0%). The results from the inhibition tests revealed that CCD was marginally present. Although IgE antibodies for cedar pollen did not react with CCD, IgE antibodies for Japanese cypress, orchard grass, and ragweed might be detected by the presence of CCD. CONCLUSION: The results of the inhibition tests revealed the obvious presence of CCD suggesting its involvement. Considering these findings, careful evaluation of patient IgE results should be performed for Japanese cypress, orchard grass, and ragweed.
