Wernicke encephalopathy and pellagra in an alcoholic and malnourished patient.

Deficiency of multiple vitamins can be identified in alcoholic and malnourished patients. We report a patient with Wernicke encephalopathy, a B1 deficiency and pellagra, a niacin deficiency. A 61-year-old Japanese man presented with generalised weakness. He had drunk alcohol heavily for more than a year without eating adequate meals. Physical examination showed disorientation, eye movement impairment, muscle wasting and a rash over the limbs. Multivitamin supplementations improved all the symptoms. Pellagra causes dementia, diarrhoea, or dermatitis, and can mimic non-specific erythaema in alcoholics. The differential diagnosis between pellagra and non-specific erythaema is important because of the treatability of pellagra by niacin supplementation.

Associations between hours worked, symptoms and health resource utilization among full-time male Japanese workers.

OBJECTIVES: To investigate the association between hours worked, symptoms experienced, and health resource utilization. METHODS: Data were collected from a nationally representative sample of households in Japan. We studied full-time male workers aged 18-65 yr who worked 100 h or more per month. First, we examined the association between hours worked and symptoms experienced. Second, we examined the association between hours worked and the type of health resource utilized, such as physician visits, over-the-counter (OTC) medication use, dietary supplement use, and complementary and alternative medicine (CAM) provider visits. We used a multivariable negative binominal model in each analysis. RESULTS: Of the 762 male workers, 598 reported experiencing symptoms at least once a month. We categorized participants based on the number of hours worked per month (h/mo): 100-200 h/mo, 201-250 h/mo, and over 250 h/mo. Compared with those working 201-250 h/mo, those working 100-200 h/mo had more frequent physician visits (rate ratio:1.67, 95% CI: 1.17 to 2.38) and those working over 250 h/mo had significantly lower rates of CAM provider visits and tended to use dietary supplements for symptoms. Participants who worked 201-250 h/mo used OTC medication most frequently. No significant association was observed between the number of hours worked and number of symptoms experienced. CONCLUSIONS: The more hours worked by full-time male workers, the more likely they were to use health resources that had a lower time requirement. Greater attention should be paid to patterns of health resource utilization among workers and their consequent influence on long-term health status.

Higher internality of health locus of control is associated with the use of complementary and alternative medicine providers among patients seeking care for acute low-back pain.

OBJECTIVES: Given that persons with a stronger belief in internal health locus of control (HLC) have been shown to comply well with medical advice, HLC internality may play an important role in low-back pain (LBP) prevention and management because it requires the patient's own commitment. Previous studies in conditions other than LBP have shown that the use of complementary and alternative medicine (CAM) is associated with high HLC internality. Here, we examined the relationship between CAM facility visits and internality of HLC in persons with LBP. METHODS: We analyzed the data from the Health Diary Study, which surveyed the health-related behavior of 3477 persons sampled from the general population of Japan. Among 2377 participants aged 18 to 75 years, 673 reported LBP during the study period. We examined CAM facility visits and HLC among 81 previously untreated LBP patients who sought care from western medical doctors or CAM providers during the 1-month study period. RESULTS: Of the 81 patients, 40 reported at least 1 CAM visit, whereas 41 visited western medical doctors only. Participants who visited CAM facilities had a higher internality score than those who visited western medical doctors after controlling for age, sex, size of residential city, and bodily pain score of the Short Form-8 Health Survey scale. DISCUSSION: Visitors to CAM facilities had a stronger belief in internal HLC. This finding suggests that visitors to CAM facilities are more sensitive to educational intervention for the self-management of LBP than those who visit western medicine. In order not to miss the opportunity of reaching these patients, the education should be more emphasized on CAM facilities.

Relationships between working status and health or health-care utilization among Japanese elderly.

BACKGROUND: As we have previously proposed redefining elderly from "65 years and over" to "75 and over" in Japan, many elderly Japanese now keep working beyond the traditional retirement age, around 60-65 years of age, in this rapidly aging society. It is important to assess the influence of working status on health and health-care utilization among elderly Japanese. METHODS: We evaluated a random sample of community-dwelling Japanese elderly, aged 55-74 years. Data were collected using a health diary strategy. For health-related quality of life (HRQOL), we used SF-8 with a physical component summary (PCS8) and a mental component summary (MCS8). Health-care utilization included visiting physicians as well as using dietary and physical complementary and alternative medicine (CAM). RESULTS: Among 679 participants aged 65-74 years (40.6% men), there were 254 (37.4%) working and 425 (62.6%) non-working. PCS8 and MCS8 were not significantly different between the working status groups. There were no differences in the rate for visiting physicians and using dietary and physical CAM between the working and non-working, except for those aged 70-74 years, who exhibited a higher rate for visiting a physician among the non-working. A higher annual personal income showed a significant association with better PCS8 (P = 0.031) and a trend towards better MCS8 (P = 0.055). The older participants were more likely to report better MCS8 than the young regardless of working status (P = 0.007). CONCLUSION: Working status itself does not appear to associate with health and health-care utilization among elderly Japanese. Working with a higher income may potentially improve HRQOL.

Health locus of control and use of conventional and alternative care: a cohort study.

BACKGROUND: Health locus of control influences health-related behaviour, but its association with healthcare use is unclear. AIM: To investigate the association between individuals' health locus of control and the use of conventional and alternative health care. DESIGN OF STUDY: Prospective cohort study. SETTING: A nationally representative random sample of community-dwelling adult households in Japan. METHOD: Health locus of control, symptom-related visits to physicians, and the use of dietary and physical complementary and alternative medicine (CAM) was measured. Dietary CAM included supplements, such as herbs and vitamins. Physical CAM included manipulations, such as acupuncture and acupressure. RESULTS: Of the 2453 adult participants studied, 2103 (86%; 95% CI [confidence interval] = 84 to 88%) developed at least one symptom during the 31-day study period. Of these symptomatic adults, 639 visited physicians (30%; 95% CI = 28 to 32%), 480 used dietary CAM (23%; 95% CI = 21 to 25%), and 156 (7%; 95% CI = 6 to 9%) used physical CAM. The likelihood of visiting a physician was not related significantly to individuals' health locus of control. Increased use of dietary CAM was weakly associated with control by spiritual powers (P = 0.028), internal control (P = 0.013), and less control by professionals (P = 0.020). Increased use of physical CAM was significantly associated with control by spiritual powers (P = 0.009) indicating a belief that supernatural forces control individuals' health status. CONCLUSION: The likelihood of visiting a physician is not affected by individuals' health locus of control. Control by spiritual powers is involved with increased CAM use. Internal control is weakly associated with greater use of dietary CAM; professional control is weakly associated with less use of dietary CAM.

Musculoskeletal pain in Japan: prospective health diary study.

The objective of this study was to understand musculoskeletal pain events and the use of health care services, including complementary and alternative medicine (CAM) in Japan. We conducted a prospective cohort study for a 1-month period using a health diary in a random sample of adults. Of the 2,226 adults, 1,065 (48%) reported new musculoskeletal pain events. The mean number of events was 3.6 in 1 month. Back, neck and knee pain were among the most frequent. The episodes of various musculoskeletal pain events was different by gender, age, city size of living, income, job status, education, body mass index, and baseline quality of life. The individuals with musculoskeletal pain were more likely to use CAM than to visit physicians. Musculoskeletal pain is very common and the individuals with musculoskeletal pain are more likely to use CAM than to visit physicians in Japan.

Gastrointestinal symptoms in a Japanese population: a health diary study.

AIM: To investigate the incidence of gastrointestinal symptoms and the nature of consequent utilization of health care services in a Japanese population. METHODS: Using self-report, we conducted a prospective cohort study of a nationally representative sample of the Japanese population over a one-month period to determine the incidence of gastrointestinal symptoms of all kinds and resultant health care utilization. Both information on visits to physicians and use of complementary and alternative medicine therapies were collected. RESULTS: From a total of 3568 in the recruitment sample, 3477 participants completed a health diary (response rate 97%). The data of 112 participants with baseline active gastrointestinal diseases were excluded from the analysis, leaving 3365 participants in the study. The incidence of gastrointestinal symptoms was 25% and the mean number of symptomatic episodes was 0.66 in a month. Abdominal pain, diarrhea, nausea, constipation and dyspepsia were the most frequent symptoms. Female gender, younger age, and low baseline quality of life were risk factors for developing these symptoms. The participants were more likely to treat themselves, using dietary, complementary or alternative medicines, than to visit physicians, except in the case of vomiting. CONCLUSION: Gastrointestinal symptoms are common in the Japanese population, with an incidence of 25%. Abdominal pain, diarrhea, nausea, constipation and dyspepsia are the most frequent symptoms. Risk factors for developing these symptoms include female gender, younger age, and low baseline quality of life.

Cocoa supplementation for copper deficiency associated with tube feeding nutrition.

OBJECTIVE: Because of an increasing number of case reports of copper deficiency associated with long-term tube feeding nutrition in Japan, we identified patients with copper deficiency associated with long-term tube feeding and described the prevalence, clinical data and cocoa treatment for these patients. MATERIALS AND METHODS: We conducted a retrospective study to identify patients who were referred from long-term care institutions and had copper deficiency associated with tube feeding. We reviewed all serum copper concentration data during a 6-year period. We also compared admission and post-treatment peripheral blood counts. RESULTS: Among 210 consecutive admissions with nutritional tube feeding from long-term care institutions (N=210), we identified 13 (6.2%) patients with copper deficiency (aged 46-91; 12 women). All patients had anemia, while most had neutropenia. The range of serum copper concentrations of these patients was 0.1-2.4 microg/L (normal; 6.8-12.8 microg/L). Their feeding formulas revealed a low copper content (5 to 12 microg per 100 kcal of each formula). Cocoa powder was used as the treatment. With cocoa supplements, the blood leukocyte count and hemoglobin significantly improved in all patients. Median leukocyte counts were 1,800 /mm(3)at admission and 6,300/mm(3) at follow-up (p=0.001). Median hemoglobin were 7.0 g/dl at admission and 10.3 g/dl at follow-up (p=0.001). Two patients developed transient tachycardia as a possible adverse effect of cocoa. CONCLUSION: We identified many cases with copper deficiency associated with tube feeding in Okinawa, Japan. Cocoa supplement appeared to be a safe and effective treatment. Increasing the copper content of Japanese tube feeding formulas should be considered for its prevention.
