With the popularization of the internet, internet addiction among the youth has received a lot of attention in recent years. While.the internet is an effective tool for: communication, the youth, who find real-life communication difficult, reportedly overuse,this aspect of the internet However, this is more of an impression based on clinical cases, with few factual findings. Therefore, the aim of this research was to study the reality of internet addiction -among university students and to examine the multilateral relationship between internet addiction and interpersonal relationships. We conducted a questibnnaire stirvey among 221 uriiversity students, analyzing the level of internet addiction, relevant interpersonal relationships, personal "charcteristics, and other factors associated with internet use. We found that the number of students who were dependent on the internet was 10 (4.7%) and the number of students with a tendency toward dependency was 98 (45.6%). In interpersonal relationships, internet addiction was significantly correlated with parental overprotection, a sense of contentment from the present parent-child rela- tionship, relationships with friends, number of friends, and availability of free time. In personal characteristics, internet addiction was significantly correlated with social skills and feelings of self-esteem. In other factors, internet addiction was significantly correlated with typing on a message board, video browsing, online gaming, use of a personal computer, desire to escape, distraction, pleasure, and connecting with others. Furthermore, we conducted a multiple regression analysis to consider the effects of these three aspects associated with internet addiction. The results suggest that internet addictionl is promoted by parental overprotection, low self-esteem, having few friends, and passive internet service usage. Thus, education is required to promote careful use of the internet to prevent internet addiction from escalating. Further, it is important to understand and support interpersonal relationships to prevent internet addiction from making life worse.

An autopsy case of caffeine intoxication related to the consumption of caffeinated products, such as energy drinks and caffeine contained drugs, was reported. Case report: A male in his early twenties was working a night shift job. After work one morning he came home and was not feeling well. He was vomiting a great deal and could not move, so his family had him lay down to rest. That afternoon they discovered his death. Although the decedent was examined by postmortem computed tomography, his cause of death could not be determined. A forensic autopsy was performed to investigate his cause of death. Autopsy findings: There were no obvious injuries on his whole body. Only slight brain edema and congestion of other organs were observed, but no significant lesions were found in his organs. A yellowish granular substance was observed in the stomach, duodenum, and small intestine. Alcohol concentration was 0.01mg/ml in the blood and urine. GC-MS and LC-MS/MS analyses did not detect any chemical substance except caffeine from his blood and urine. By LC-MS/MS analysis, the caffeine level (p g/mL) was 182, 71, and 10700 in the blood, urine, and gastric contents, respectively. Results and discussion: The fatal level of caffeine in blood has been reported as >100 u g/ mL. Thus, the cause of death was diagnosed as caffeine intoxication. It was revealed that he had consumed many energy drinks to stay awake and alert. Because he had a history of feeling ill and vomiting, it is suspected that he had an excessive intake of caffeine. Energy drinks, unlike most medicines, are able to be consumed repeatedly, and caffeine intoxication is a possible result. The reporting of this case will enlighten the danger of repetitious and chronic consumption of caffeinated products, such as energy drinks and caffeine contained drugs.

While many Japanese nationals are considered to have problems with pachinko and pachisuro (Japanese slot machines), the factors contributing to the process by which gambling disorder-is aggravated remain unclear. Therefore, the aim of this study was to establish baseline data for measures to prevent the further escalation of this gambling disorder; To elucidate the contributing factors, a self-administered questionnaire was distributed to pathological gamblers. The survey items were composed of the following basic attributes; scores on the South Oaks Gambling Screen (SOGS); gambling motivation; matters arising, after gambling behavior; remedies for excessive gambling; the Kessler 6 (K6); the CAGE (Cut down, Annoyed, Guilty, Eye opener) questionnaire; and the 8-item Family Adaptability and Cohesion Evaluation Scale at Kwansei Gakuin IV (FACESKGIV-8). The results of hierarchical multiple regression analysis using SOGS scores as the dependent variable indicated that the variables determined to contribute to the aggravation of gambling addiction were age, sex, past employment experience in the service sector, obtaining money as a motivation for gambling, and seeing limits as a remedy for excessive gambling. Because gamblers tend to fixate on money and experience increasing difficulty devoting attention to other matters as gambling problems grow more serious, the results of this study suggest the need to provide environments that will enable affected individuals to reflect on their own style of gambling at the stage at which their gambling behavior begins to exceed the scope of their own revenue.

Caffeine-containing drinks are popular daily beverages worldwide and highly concentrated caffeine in the form of tablets is easily obtainable in local chemists. It is common to detect caffeine in toxicological screens in autopsy cases, but we always have to take in account that caffeine itself possesses toxicity which may sometimes lead to death The case was a 44-year-old woman who was found dead in her room one day in June. Empty packages of 'Estaron Mocha 12®, accounting for 14 tablets, were found at the scene. The autopsy showed nothing remarkable suggesting external forces, apart from white granules in her stomach. Toxicological analysis revealed 127 mg/L of caffeine concentration in the deceased's blood, which was considered to be fatal. Caffeine intoxication cases have been reported from many countries. Some are caused by accidental overtake of energy drinks, and many others are caused by intentional intake of caffeine tablets. We think that some restrictions will be effective to prevent this kind of death.

The purpose of the present review is to explain the mechanism of alcohol-induced asthma in Japanese. An oral ethanol provocation test was performed in Japanese asthmatics to measure pulmonary function, blood ethanol, acetaldehyde and histamine. Acetaldehyde dehydrogenase 2 (ALDH2) genotype was determined by polymerase chain reaction (PCR) and ethanol patch test. Human bronchi and mast cells were stimulated with acetaldehyde in vitro. Approximately half of the asthmatic subjects developed bronchoconstriction with concomitant increases in blood acetaldehyde and histamine, which was associated with genetically reduced ALDH2 activities. In vitro acetaldehyde stimulation induced bronchoconstriction and degranulation of human mast cells. Collectively, as a metabolite of alcohol, the elevation of acetaldehyde following alcohol consumption induces airway mast cells to release histamine, which result in exacerbation of asthma in susceptible population.

A 48-year-old Japanese woman with >10 years history of alcoholic had been falling repeatedly during 1 week before her death. She complained of nausea and did not eat or drink for 2 days. Thereafter, she became drowsy and she was transferred to the hospital. On arrival at the hospital, she had cardiopulmonary arrest and died soon after. Although blood tests showed metabolic ketoacidosis, a hemorrhagic lesion was also found in the brain by computed tomography. To determine the cause of death,. a forensic autopsy was performed on the next day. At autopsy, cerebral contusion, skull fracture, and subdural hemorrhage caused.by the head injury received after falling were found. Histological examination showed fatty changes and Mallory bodies in the liver. There was a marked increase in ketone bodies, especially β -hydroxybutyrate, in postmortem blood examination. Therefore, the cause of death was diagnosed as alcoholic ketoacidosis. Accurate diagnosis of mild trauma and metabolic disease is difficult by postmortem computed tomography; therefore, autopsy is required for sudden death. In this case, the cause of death and accompanying traumatic lesions that were compatible with her history was clarified by autopsy. Furthermore, because the blood was taken at the time of cardiopulmonary arrest, we.obtained reliable data from the terminal stage of alcoholic ketoacidosis. This case demonstrates the physiological and pathological changes in sudden death of a patient with alcoholic.

This article is an extension of a presentation with the same title given at the Japanese Alcohol, Nicotine & Drug Addiction Conference in Kobe on October 13th 2015: Firstly, a brief overview of support activities and services within Proyecto Hombre is given outlining the advanced assistance programs for supporting and treating addiction. problems. Secondly, it lays out the profile of persons with alcohol and drug problems as taken from "Proyecto Hombre Observatory Report 2014" vhich has informed the reality of adult users' life situation based on a series of indicators from the EuropASI, while they were being treated at Proyecto Hombre 27 Centers in Spain between 1 January, 2014 and 31 December, 2014. The sample consists of 1941 people treated during 2014 after application of the criteria for validation of the questionnaire. The profiles so obtained enable the design of treatment programs according to their specific situation in Proyecto Hombre. In order to allow some guidance to Japanese investigators and social workers regarding the design of treatments programs based on current user situation, this article draws attention to general sociodemographic data as well as data notable for its variation by gender and also by substance, and draws limited conclusions based on these.

A cognitive behavioral therapy program entitled "STEM" was implemented with 42 drug dependent outpatients at Okayama Psychiatric Medical Center. Characteristics of 1 group who completed the program were examined, with the effectiveness of the program evaluated through monitoring longitudinal changes over a period of 8.5 months. Results showed that the percentage of patients who completed the program was 52.4% (22 out of 42 people), those who completed had a longer educational history than the dropouts, a high proportion of those who completed held some form of employment and that their motivation to recover was high. Evaluation results of the program effectiveness showed significant improvement in short-term drug self-efficacy, with a tendency for later improvement in feelings and emotions also observed. While a certain level of effectiveness was proven, approximately half the group dropped out; so it is necessary to consider alternative options at an early stage for participants with a high risk of dropout, such as strengthening individual support based on their specific characteristics.

Purpose: The purpose of this study was to evaluate the efficacy of the Serigaya Methamphetamine Relapse Prevention Program (SMARPP), which is the workbook-based group therapy for individuals with drug dependence, through investigating 1-year follow-up outcomes.

Method and subjects: The sample was drawn from 231 outpatients diagnosed as DSM-IV substance use disorder, who had firstly consulted the drug dependence clinic of the Center Hospital, National Center of Neurology and Psychiatry between September 2009 and June 2013. Of the 231 potential subjects, 79 had participated in SMARPP at least once, and finally 37 who had continued contact this clinic for more than 1 year after due-day of finishing the first SMARPP course were determined as the subjects. We collected the outcome information retrospectively based on clinical records.

Result: At the 1-year follow-up point, 67.6% of the subjects had continued abstinent at least for a month, and 60% of them had continued full-abstinent for more than 1 year. One of the factors which influenced their abstinence was "having no experience of using new psychoactive substances" (p = 0.029). As for 70.3% of subjects, drug-use frequency decreased and the only factor for their improvement was "participating in SMARPP many times" (p = 0.040). Of the subjects, 23 patients corresponded to methamphetamine use disorder, and 65.2% of them had continued abstinent at least for a month at the 1-year follow-up point. Additionally, 60% of them had continued full-abstinent for more than 1 year.

Discussion and conclusion: Our study demonstrated possible effectiveness of SMARPP for patients with drug use disorder, especially methamphetamine-use-disorder. The factors of abstinence or decrease of drug-use frequency may be to participate in SMARPP many times, not to abuse "not illegal" drugs such as new psychoactive substances or hypnotics/anxiolytics and to continue treatment for more than 1 year after due-day of finishing the program.

One of the alcohol-related goals in Japan's health promotion campaign called Health Japan 21 (secondary term) is to reduce the number of high-risk drinkers (20 years old or above) who consume 40g or more pure alcohol/day in men and 20g or more in women by year 2022. To achieve this goal, a further expansion of screening and brief intervention (SBI) in the medical setting is essential. In this research, realistic and cost-effective SBI scenarios in Japan were investigated based on international systematic review and clinicians' opinions from a semi-structured interview. Several SBI scenarios were built with 2 levels of intervention based on the AUDIT scores of 8-15 (brief advice) and 16-19 (brief advice and counseling, continuous intervention), and a simulation was conducted by applying different probabilities and success rates into the scenarios. Information associated with preparation and implementation of SBI at the 2 levels was also estimated and annual costs of SBI per drinker were calculated. It was found that approximately 2,390,000 and 530,000 high-risk drinkers require brief and extensive interventions, respectively. Furthermore, incremental costs per quality-adjusted life year (QALY) gained were calculated at 723,415 yen for brief intervention and 944,762 yen for extensive intervention, suggesting cost-effectiveness of SBI in Japan. Given the limited national healthcare budget and operational challenges such as time to provide SBI especially in the primary care setting in Japan, roles of healthcare providers and wider use of information technology were discussed with some suggestions. Furthermore, lighter and more frequent interventions at various levels and not only at the medical setting but also at multiple social settings (such as workplace and among family and friends) were discussed to increase the cost-effectiveness of SBI and to keep the number of high-risk drinkers who have successfully reduced their alcohol consumption.
