Alcohol dependence was shown to affect overall HRQOL and its domains, including general health, physical and mental health, general and social functioning, activities of daily living, pain and sleep. The evidence demonstrating that alcohol dependence is a primary cause of impairments in overall HRQOL, general health, mental and physical health and social functioning was fairly strong. Treatment interventions helped improve HRQOL and its aforementioned domains. The reduction or cessation of alcohol use facilitated these improvements; however, it was not reported to be predictive of improvement in all instances where improvement was reported. Depression was associated with further decreases in HRQOL. Personality disorders contributed to the severity of social functioning impairment.

This article describes a widespread outbreak of hepatitis A virus (HAV) infection amongst drug abusers in Finland. Although attempts to demonstrate the virus in amphetamines failed, the infection was assumed to be linked to intravenous use of the drug. The unusual mode of transmission prompted us to analyse possible atypical clinical features as well as the spread of the virus to the general population, nowadays practically without protective immunity. Serologically verified cases that occurred in Helsinki were interviewed, their hospital records were analysed and their contacts were serology tested. Amphetamine lots, as well as faecal samples from patients, were examined with RT-PCR. Detailed information was obtained from 238 subjects, among whom 131 admitted drug abuse and 67 cases were classified as secondary cases. Phylogenetic analysis of virus strains from HAV-infected cases suggested a common origin, and epidemiological observations linked it with particular lots of amphetamine. Three cases died, and 3 presented with severe clinical disease. Icterus was more common among i.v. drug abusers than others. Infection with hepatitis A virus was probably related to the faecal contamination of amphetamine associated with the transportation of the drugs in the gastrointestinal tract.

Alcohol dependence profoundly affects the family and social network of the afflicted person. The most frequent difficulties in activities and participation have to do with interpersonal interactions, economic and work life, dealing with aggression and legal problems. Problems with high-risk behaviours and in seeking appropriate treatment are also common. Treatment targeted at reduction or cessation of alcohol use is effective in reducing these psychosocial difficulties. The ICF offers a structure for systematic evaluation of the wide range of difficulties encountered in alcohol dependence.
