    ABSTRACT: To refine estimates of the burden of alcohol-related oesophageal cancer in Japan. We searched PubMed for published reviews and original studies on alcohol intake, aldehyde dehydrogenase polymorphisms, and risk for oesophageal cancer in Japan, published before 2014. We conducted random-effects meta-analyses, including subgroup analyses by aldehyde dehydrogenase variants. We estimated deaths and loss of disability-adjusted life years (DALYs) from oesophageal cancer using exposure distributions for alcohol based on age, sex and relative risks per unit of exposure. We identified 14 relevant studies. Three cohort studies and four case-control studies had dose-response data. Evidence from cohort studies showed that people who consumed the equivalent of 100 g/day of pure alcohol had an 11.71 fold, (95% confidence interval, CI: 2.67-51.32) risk of oesophageal cancer compared to those who never consumed alcohol. Evidence from case-control studies showed that the increase in risk was 33.11 fold (95% CI: 8.15-134.43) in the population at large. The difference by study design is explained by the 159 fold (95% CI: 27.2-938.2) risk among those with an inactive aldehyde dehydrogenase enzyme variant. Applying these dose-response estimates to the national profile of alcohol intake yielded 5279 oesophageal cancer deaths and 102 988 DALYs lost - almost double the estimates produced by the most recent global burden of disease exercise. Use of global dose-response data results in an underestimate of the burden of disease from oesophageal cancer in Japan. Where possible, national burden of disease studies should use results from the population concerned.

    ABSTRACT: No nationally representative survey of irritable bowel syndrome (IBS) among adolescents has ever been performed in Japan. In the present study, we aimed to clarify the prevalence of IBS among Japanese adolescents and the factors associated with it. The items related to the diagnostic criteria for IBS based on the Rome III Diagnostic Criteria for Functional Gastrointestinal Disorders was included in a cross-sectional nationwide survey of 'alcohol consumption and smoking habits among junior and senior high school students'. The participating schools were sampled from among all junior and senior high schools in Japan using the cluster sampling method, and self-administered questionnaires were sent to the selected schools by mail. Among 99,416 questionnaires that were collected, data from 98,411 valid responses were analyzed. The results showed that the prevalence of IBS was 18.6%. Although no sex difference was observed in the overall prevalence of IBS, the prevalence of diarrhea-predominant IBS was higher among boys than among girls, and the prevalence of constipation-predominant IBS was higher among girls than among boys. The prevalence of IBS increased with progression of the school grade, and there were the significant relationships between IBS and sleep-phase delay and insomnia symptoms. IBS was also significantly associated with poor mental health status. These results indicate that IBS is common among junior and senior high school students, and associated with lifestyle and mental health. This article is protected by copyright. All rights reserved.

    ABSTRACT: Alcoholics have a high prevalence of nicotine dependence, and smoking is a major contributor to their high mortality. Three weeks after admission to an addiction center in Japan, 193 alcoholic men who were participating in an 11-week concurrent inpatient smoking cessation and alcohol abstinence programs filled out an anonymous self-report questionnaire regarding smoking and drinking, and 6 months after the completion of the programs, 83 patients were asked to respond to a mailed questionnaire about their smoking and drinking status. Of the 193 subjects, 73.3% were current smokers, but many were highly motivated in regard to both smoking cessation and alcohol abstinence. The subjects' scores on a 0 to 10 point scale for rating motivation and confidence in regard to smoking cessation and smoking urge were significantly correlated with each other and with their scores for motivation and confidence in regard to alcohol abstinence and drinking urge. Three weeks after admission, varenicline treatment was well-tolerated, and the varenicline group had a high rate of smoking cessation than the smoker group not treated with varenicline (67.7% vs. 44.6%, p = 0.012). Forty-six (55.4%) of the 83 subjects who were mailed the questionnaire responded, and the drinking category was 'totally abstinent' in 35 subjects (42.2%), and 'mostly abstinent' in another 4 subjects (4.8%). Seventeen (20.5%) of the 83 subjects were non-smokers before treatment, but after treatment, 23 (50.0%) of the 46 responders and 20 (51.3%) of the 'totally or mostly abstinent' 39 responders were total or almost non-smokers. The response rate of 'totally or mostly abstinent' was higher among the 17 non-smokers before treatment than among the 66 smokers before treatment (70.6% vs. 40.9%, p = 0.033), and the age-adjusted odds ratio (95% confidence interval) for the response of 'totally or mostly abstinent' was 3.30 (1.03-10.56) for the non-smokers before treatment (vs. the smokers before treatment). In conclusion, smoking status had a great impact on the drinking status of treatment-seeking alcoholic men, and smoking cessation should be recommended to smoking alcoholics.

    ABSTRACT: Since the prevalence of alcohol use disorders is high among cases of drunk driving (DD), it is said that treatment interventions should be directed at preventing DD. The National Police Agency introduced a specialized two-day lecture program including Brief Intervention (BI) for drivers whose licenses had been revoked at four out of 47 prefectures in 2010. Once the driving license was revoked, he/she was compelled to attend a two-day lecture before retaking the driver's license examination. Before the new program was introduced, all of the traffic offenders attended the same lecture regardless of the reason for the revocation of their drivers' licenses. In this presentation, we compare the efficacy between the new and previous programs. In 2010, 10,745 traffic offenders participated in the lecture (681 were in the new program, while 10,064 were in the conventional program). We compared the rate of traffic offences within a year of attending the program between the two groups. The prevalence of arrests for DD and other traffic offenses in the subjects of the new program were 0% and 15.6%, respectively, while the corresponding figures for participants of the conventional program were 0.54% and 20.9%. These results suggest that BI had deterrent effects against repetition of all traffic offenses including DD, and that the treatment program should be adopted to deter DD.

    ABSTRACT: Although alcohol-related dementia occurs under ethanol intoxication with coexisting nutritional deficiency, the culprit lesions for cognitive decline of alcoholics remain fully unexplored. After consecutively recruited 113 alcoholics (54.6 ± 6.5 years old) was divided into an alcoholic with cognitive decline group (ALD, n = 58) and cognitively normal alcoholic group (ALN, n = 55), VBM for automatic detection of gray matter and SPM software for the analysis were used to make two sets of comparisons, one between a normal control group (n = 60) and the ALN, and the other between the ALN and ALD. The ALD was older with a longer duration of alcohol dependence and had a lower BMI than the ALN. The gray matter volume of the alcoholics was lower than that of the controls and it was negatively correlated with age. The ALN had more enlarged sylvian/longitudinal fissures and third/lateral ventricles, and a more atrophic in the frontal/temporal lobes and cerebellum than the control group. Parahippocampal/hippocampal atrophy was specific to ALD and atrophy of the thalamus and enlargement of the third ventricle were more severe in the ALD group than in the ALN group. The parahippocampal and hippocampal cortices may play a crucial role in the retention of short-memory in alcoholics.

    ABSTRACT: In Japan, in-patient treatment hospitals for alcohol dependence (AD) are located throughout the country. However, comprehensive studies regarding predictors of treatment outcomes after discharge have not been conducted sufficiently. Therefore, we analyzed data obtained from the Japan Collaborative Clinical Study on Alcohol Dependence (JCSA) to examine this issue.

    ABSTRACT: The treatment of alcohol use disorder (AUD) is influenced by the culture of each society, the policy of the medical systems, and the difference in clinical characteristics of the patients. In Japan, a hospitalized treatment for comparably longer (2-3 months) period is more likely to be selected. Japanese alcoholic patients tend to develop AUD later in their life and comorbid antisocial personality disorder and polydrug addiction exist less frequently compared to Western countries. Japanese therapists have developed several unique treatment programs such as Naikan therapy and Morita therapy, which are inspired by Buddhism and Zen meditation. Danshukai, a self-help group of AUD, was established in Japan based on AA, but there are some differences between Danshukai and AA. The comparison of such differences between Japan and other countries would make clear the effect of the cultural aspects on the treatment of AUD. We would like to present the unique Japanese treatment of AUD and discuss the influence of the culture, which would lead to increase the outcome of the treatment of AUD among different cultural societies.

    ABSTRACT: We registered 193 alcohol-dependent patients who visited our hospital. The six ICD-10 criteria items for alcohol dependence were checked at the time of the first visit in each case. The correlations of the checked items among the ICD-10 diagnostic criteria were then examined statistically. Furthermore, we investigated the relation between each criteria item and biochemical blood markers. Three diagnostic items in the ICD-10, (A) strong desire, (B) difficulties in controlling alcohol intake, and (E) progressive neglect of alternative pleasures or interests, were strongly correlated with each other and were thought to form the core symptoms of alcohol dependence. Two major diagnostic items, (C) physiological withdrawal state, and (D) evidence of tolerance, were not as strongly related to the former three items and seemed to be derivatives of the core symptoms. Conventional biochemical markers, such as γ-GT and MCV, which indicate a large quantity of drinking, were not associated with the ICD-10 diagnostic items. Three diagnostic items in the ICD-10, (A), (B), and E), were strongly related to each other and were considered to be the core symptoms of alcohol dependence. The core symptoms might be adapted for other forms of substance-use dependence and behavioral addiction.

    ABSTRACT: Internet technologies have made rapid progress, bringing convenience to our daily life. On the other hand, Internet overuse (IOU) and Internet addiction (IA) have reportedly become serious health and social problems across the globe. Recently Internet gaming disorder criteria have been proposed in the section of Conditions for Further Study of DSM5. Many surveys have reported that many IOU & IA patients have contracted other mental disorders and exhibit some psychiatric and physical symptoms (e.g., weight loss, reduced ability to exercise, nutrition disorder). Attention Deficit Hyperactivity disorder (ADHD), sleeping disorders, depression, obsessive compulsive disorder, and phobic anxiety disorder are extremely common comorbid mental disorders (CMD) with IUD & IA. Because CMD breaks the usual rhythm of the activities of daily living of IOU & IA patients (e.g., eating meals and sleeping), and prevents the affected patients from participating in social activities (e.g., going to schools or work, participating in sports or other hobbies), CMD causes exacerbation of all IOU & IA symptoms. It has been reported that effecting a cure of some aspects of CMD often leads to the relief of IOU & IA. The diagnosis and the treatment of CMD are therefore very important.

    ABSTRACT: Individuals with inactive aldehyde dehydrogenase-2 (ALDH2) show adverse reactions after ethanol intake, which is known to suppress the occurrence of alcohol use disorders (AUDs), nonetheless, some individuals with inactive ALDH2 do become alcoholics. It has been suggested that these individuals may carry factors facilitating the development of AUDs. In this series of studies, we attempted to identify the risk factors for AUDs, and to replicate the validity of existing factors, using the unique characteristics of alcoholics with inactive ALDH2 or the AIA model. The subjects were hospitalized male alcoholics with inactive ALDH2 (N = 91), male alcoholics with active ALDH2 (N= 81), and 201 age-matched healthy males. To examine the risk factors, we assessed the psychological characteristics of the study participants, and compared the results among the three groups. Among 15 known self-reported questionnaires, we employed the Temperament and Character Inventory (TCI) for this study. TCI is a 230-item self-reporting questionnaire used to assess the following four temperament dimensions: Harm avoidance (HA), Novelty seeking (NS), Reward dependence (RD), and Persistence (P); in addition, it is also useful to measure the following three character dimensions: Self-directedness (SD), Cooperativeness (C), and self-transcendence (ST). The score for HA was higher, while the scores for P, SD and C were lower in the alcoholics than in the control subjects. These results suggest that these personality characteristics may play a role in facilitating the development of AUDs.

    ABSTRACT: Psychological interventions are important in the treatment of dementia to reduce the cognitive dysfunction and behavioral and psychological symptoms of dementia (BPSD). However, there are few reports that highlighted psychological interventions for dementia patients with comorbid alcohol use disorder, partly because abstinence from alcohol tends to improve the cognitive functions naturally in these individuals. Here we report a trial to apply psychological interventions for the dementia patients with alcohol use disorder.
