Glutamic acid in withdrawal and weaning in patients classified according to Cloninger's and Lesch's typologies.

Aims: Though glutamic acid is well known as a working excitatory in the CNS, its impact on the modulation of alcohol withdrawal symptoms and withdrawal fits are not yet clear. The study has been undertaken to examine the levels of glutamic acid in chronic alcohol-dependent patients at different stages of alcohol withdrawal and weaning and to examine any existence of any differences according to Cloninger's and Lesch's typologies.

Patients And Methods: One hundred and fifty-nine alcohol-dependent patients were assessed according to Cloninger's and Lesch's typologies and related to abstinence duration, age, and gender.

Epidemiology of substance use in a representative sample of 18-year-old males.

Aims: To assess recent drug use through urine testing as well as the prevalence of tobacco and alcohol dependence among young males and to analyse the associations between tobacco dependence and cannabis use (delta-9-tetrahydrocannabinol, THC), tobacco dependence, and alcohol dependence as well as between THC use and other illicit drug use.

Methods: Urine samples were collected, and nicotine and alcohol questionnaires were administered. Carbon monoxide was assessed in exhaled air.

Craving and other characteristics of the comorbidity of alcohol and nicotine dependence.

Purpose: In this cross-sectional study we compared alcohol-dependent smokers and non-alcohol-dependent smokers with respect to intensity of nicotine dependence, craving conditions, sleep disturbances, comorbidity with major depression, reasons for smoking, accompanying somatic diseases and patients' prolonged abstinence from smoking during the 3 years preceding the study.

Subjects And Methods: Fifty-one alcohol-dependent smokers and 327 non-alcohol-dependent smokers diagnosed as ICD-10 and DSM-IV-nicotine dependent, were investigated by means of the Fagerström Test for Nicotine Dependence, the Lübeck Craving-Recurrence Risk Questionnaire and the Lesch Alcohol Dependence Typology (both adapted to smoking).

Results: The intensity of nicotine dependence was more enhanced in alcohol-dependent smokers compared to non-alcohol-dependent smokers.

CDT values are not influenced by epithelial cell apoptosis in chronic alcoholic patients-preliminary results.

Carbohydrate-deficient transferrin (CDT) has been well established as a marker for high alcohol consumption. As studies concerning the specificity of CDT in patients with liver disease have shown controversial outcomes, efforts to illuminate mechanisms leading to impaired CDT specificity in this patient group cannot yet be considered successful. Evidence of apoptosis as examined in 72 alcohol-dependent patients using serum contents of caspase-related M30 monoclonal antibody significantly correlated with aspartate aminotransferase, alanine aminotransferase, and gamma-glutamyl transpeptidase but did not influence CDT levels.

The Austrian multicentre study on smoking: subgroups of nicotine dependence and their craving.

Background: The misconception of tobacco smoking as a 'bad habit' has been replaced by a diagnosis of addiction. Although help to quit is offered by nicotine replacement, antidepressants and psychotherapeutic support, there is no cure yet. One cause of impediment might be psychiatric comorbidity.
