Abstract
BACKGROUND Autonomic symptoms in alcohol withdrawal syndrome (AWS) are associated with a sympathetic-driven imbalance of the autonomic nervous system. To restore autonomic balance in AWS, novel neuromodulatory approaches could be beneficial. We conducted a pilot trial with percutaneous auricular vagus nerve stimulation (pVNS) in AWS and hypothesized that pVNS will enhance the parasympathetic tone represented by a reduction of pupillary dilation in a parasympatholytic pharmacological challenge. METHODS Thirty patients suffering from alcohol use disorder, undergoing AWS, and stable on medication, were recruited in this open-label, single-arm pilot trial with repeated-measure design. Peripheral VNS (monophasic volt impulses of 1 msec, alternating polarity, frequency 1 Hz, amplitude 4 mV) was administered at the left cymba conchae for 72 h, followed by pupillometry under a tropicamide challenge. We assessed craving with a visual analog scale. We used pupillary mean as the dependent variable in a repeated-measures ANOVA (rmANOVA). RESULTS A repeated-measures ANOVA resulted in a significant difference for pupillary diameter across time and condition (F(2,116) = 27.97, p < .001, ηp2 > .14). Tukey-adjusted post hoc analysis revealed a significant reduction of pupillary diameter after pVNS. Alcohol craving was significantly reduced after pVNS (p < .05, Cohen's d = 1.27). CONCLUSION Our study suggests that pVNS activates the parasympathetic nervous system in patients with acute AWS, and that this activation is measurable by pupillometry. To this end, pVNS could be beneficial as a supportive therapy for AWS. Potential confounding effects of anti-craving treatment should be kept in mind.

Abstract
BACKGROUND This study intended to determine whether certain traits of temperament are associated with former and current ADHD symptomatology in a non-clinical sample of 18 year old males. METHODS We performed a cross sectional descriptive study of 3280 men during the examination for military service. The investigation included a socio-demographic questionnaire, screening for substance abuse, temperament (TEMPS-M), past (WURS) and current (ADHD symptom checklist) ADHD symptomatology. RESULTS We found a correlation of cyclothymic (p<.001), irritable (p<.001) and anxious (p<.05) temperament with occurrence and severity of past and present ADHD symptomatology. No significant correlation has been detected for hyperthymic and depressive temperament. Judged retrospectively, ADHD symptoms were strongly consistent over time. LIMITATIONS The sample consists of men only. These had to be fit enough to be enlisted for military service; men with severe mental or physical disorders were thus excluded. Furthermore, the cross-sectional study design does not allow making conclusions about the temporal relationships between ADHD symptoms and substance misuse. CONCLUSIONS These results indicate that a temperament based approach towards those affected by ADHD might be useful. Subtyping ADHD by integrating temperament profiles in diagnosis and treatment of the disorder could help explain some of the heterogeneity of the disease.

Abstract
AIMS The first aim of this study is to investigate the impact of different temperaments in opiate dependency patients. The second aim of this study is to define therapy relevant subgroups in opiate addiction for further basic clinical research and therapy. METHODS In the time period from September to November 2010, 101 patients (72 males and 29 females) which fulfilled the diagnosis of opiate dependency according to DSM-IV-TR were recruited consecutively. All patients were in treatment at the Oum El Nour rehabilitation center/Lebanon (Inpatient and Outpatient groups). Lesch Alcoholism Typology modified for assessment of opiate addicts, and the briefTEMPS-M, Arabic version were used. RESULTS The organic Type IV group was the most prevalent (48.5%) among the sample followed by the Affective Type III group (41.6%) and the minority represented the two other types (I & II). The organic Type IV group represented the major type in the cyclothymic and anxious temperament. In the contrary the other two groups (I & II) were the minority among the cyclothymics.

Abstract
BACKGROUND Suicide is a major health problem accounting for up to 1.5 percent of all deaths worldwide and represents one of the most common causes of death in adolescents and young adults. A number of studies has been performed to establish risk factors for suicide in patients with psychiatric disorders including temperamental features. This study set out to assess the relationship between suicidal ideation and temperament in young adults. METHODS A cross-sectional sample of healthy college students (n=1381) was examined using a self-rating questionnaire. Suicidal ideation, social background, educational status, substance abuse, and affective temperament according to TEMPS-M were assessed. Predictors of lifetime suicidal ideation were examined in multivariate logistic regression analyses. RESULTS Suicidal ideation was reported by 12.5% of all subjects at some point in their life and was higher in nicotine dependents, youth with alcohol related problems and users of illicit substances as well as in youth with lower educational status. Lifetime suicidal ideation was associated with the anxious, depressive and cyclothymic temperament in both sexes and the irritable temperament in males. These results remained significant after adjustment for smoking status, frequency of alcohol consumption, drug experience and educational status in a multivariate logistic regression analysis. LIMITATIONS The use of self-rating instruments always reduces objectivity and introduces the possibility of misreporting. CONCLUSIONS Considering the fact that many subjects completing suicide have never been diagnosed with mental disorders it might be reasonable to include an investigation of temperament in screenings for risk of suicide. This might be especially useful for health care professionals without mental health care background.

Abstract
AIMS The aim of this study was to assess the impact of temperamental traits in alcohol dependent patients on the course of illness. METHODS The case files of 116 alcohol dependent patients, according to ICD-10 and DSM-IV-TR, were examined retrospectively. All patients were in treatment between 02/08 and 03/09 at the Psychiatric Department of the General Hospital Vienna, either at the alcohol outpatient clinic or the psychiatric ward, which has the treatment focus on alcohol dependence. The brief TEMPS-M auto-questionnaire was used to assess the temperamental distribution. The dimensions of alcohol dependence have been assessed using the Lesch Alcoholism Typology, a computerized structured interview. The potential effect of temperamental scores on various outcomes describing the course of illness is investigated using multi-variable regression models. RESULTS Cyclothymic score was the only temperament which significantly influenced the age of onset of alcohol abuse and age of onset of alcohol dependence. Backward selection among temperaments exhibits depressive temperament as most important effect regarding the likelihood of suicide-attempts in the patient's case history and anxious temperament as most important effect regarding having psychiatric treatment focusing on alcohol dependence prior to current in- or outpatient stay. LIMITATIONS The sample size of this study is small compared to the number of investigated outcomes and temperaments. Further, a healthy control group, matched for age and gender, was not available for comparison of the temperament sub-scores. CONCLUSION Dominant cyclothymic, but also depressive and anxious temperament, seem to be negative predictors for the course of illness in alcohol dependence. Regarding positive long term outcome specific evidence based medical treatment approaches are needed for these patients.

Abstract
BACKGROUND During the last 20 years Austrian psychiatric services underwent fundamental changes, as a focus was set on downsizing psychiatric hospitals. Little is known about how restructuring of mental health services affected patients with major depression and suicide rates. METHODS Monthly hospital discharges from all hospitals in Austria with the diagnosis of unipolar major depression as primary reason for inpatient treatment were obtained for the time period between 1989 and 2008. These data were correlated with relevant parameters from the general health system, such as number of hospital beds, suicide rate, density of psychotherapists and sales of antidepressants. RESULTS While the number of psychiatric beds was reduced by almost 30%, the total annual numbers of inpatient treatment episodes for depression increased by 360%. This increase was stronger for men than for women. Further on this development was accompanied by a decrease in the suicide rate and an improvement in the availability of professional outpatient mental health service providers. LIMITATIONS Only aggregated patient data and no single case histories were available for this study. The validity of the correct diagnosis of unipolar major depression must be doubted, as most likely not all patients were seen by a clinical expert. CONCLUSIONS Our data show that although inpatient treatment for unipolar major depression dramatically increased, reduction of psychiatric beds did not lead to an increase of suicide rates.

Abstract
Objective. To validate NAT (NETER's alcoholic typology), taking into account the differentiated distribution of the measures used as external criteria in alcohol-dependent sub-groups and its relationship with Lesch's alcoholic typology (LAT). Method. A sample of 133 alcohol-dependent patients integrated in the alcoholism unit of the Psychiatric Service of Santa Maria University Hospital were included in the study. Results and Conclusions. Convergent validity was assured by the agreement between the subtypes of the two typologies (NAT and Lesch), considering the same underlying model of alcoholism development: anxiopathic subtype of NAT and Type II (model of anxiety, alcohol as conflict solution) of Lesch and the tymopathic subtype of NAT and type III (model of depression, alcohol as antidepressant) of Lesch. Discriminant analysis (external criteria) showed significant differences between the subtypes in the following variables: gender; tobacco; beer and whisky consumption; daily average of drinks; clinical conditions such as delirium tremens, alcoholic blackouts and seizures; severity of alcohol-related problems; psychological dimensions such as psychological maturity and extroversion; and suicidal ideation during the alcohol consumption period. A more exhaustive description of alcoholic sub-groups may improve genetic studies of alcoholism and provide the alcoholic patient with an adequate specific therapeutic protocol.

Abstract
A study recently finished by our research group elucidated the effectiveness of flupenthixol decanoate (FLX) in maintaining abstinence in detoxified alcoholics. Flupenthixol decanoate is an established antipsychotic drug, which is well known for its mild antidepressant and anxiolytic activity as well as for its minimal sedation at low doses. It blocks dopamine binding at a number of receptor subtypes, primarily at D-1, D-2, D-3 and with less affinity at D4-receptors. It also affects serotonin binding at 5-HT2A and 5-HT2C receptors. In a double-blind placebo-controlled multicenter trial, 77 women and 204 men suffering from moderate or severe DSM-II-R alcohol dependence were randomly assigned to either 10 mg FLX or placebo both injected every second week over a period of 24 weeks (treatment phase) succeeded by a medication-free 24-weeks follow-up period. In the overall analysis the number of patients relapsed after 24 weeks of treatment (=main criterion of efficacy) was significantly higher in the FLX treated group (85.2%) than under placebo (65.5%). However, when differentiating this result according to sex the analysis revealed a gender-related discrepancy: while male patients had an almost 4-fold higher risk to relapse under FLX than under placebo (OR=3.95) this risk was barely elevated for female patients (OR=1.51). A significantly negative outcome due to FLX treatment was restricted to male alcoholics solely. In conclusion, gender-related differences to pharmacological relapse prevention with FLX have probably contributed to a better treatment outcome in women than in men.

Abstract
Alcohol abuse and alcoholism cut across gender, race and nationality. In general, more men than women are alcohol dependent or have alcohol problems, but women are at greater risk for adverse effects and alcohol-related diseases. Death rates among female alcoholics are 50 to 100 percent higher than those of men. Major physiological impairments, the diagnostic distribution, the psychosocial consequences and their implication on treatment will be outlined.

Abstract
OBJECTIVE The primary aim of this paper was to compare the effects of flupenthixol and risperidone on subjective quality of life and attitude towards medication in chronic schizophrenic patients with mainly negative symptoms. In a spectrum ranging from its typical end "haloperidol" to its atypical end "clozapine", flupenthixol has typical and atypical characteristics. METHODS The effects of flupenthixol versus risperidone were investigated in a multicenter, double-blind trial, whereas subjective quality of life was assessed by means of the EuroQuol-Visual Analogue Scale and the patient satisfaction questionnaire. The attitude towards medication was assessed by means of the Drug Attitude Inventory-30 (DAI-30). RESULTS Mean daily dose of study medication was 6.6 (SD 2.9) mg/day flupenthixol and 3.6 (SD 1.2) mg/day risperidone. Both groups showed a significant improvement regarding subjective quality of life and positive attitude towards medication. Especially the categories "control of their thoughts", concentration and "feeling better in general" ameliorated in both groups. In the flupenthixol group, the "ability to cope with stress", "feel more relaxed" and the "ability to achieve something" improved significantly more than in the risperidone group. CONCLUSIONS (1) The spectrum of schizophrenia can be treated effectively with different neuroleptic treatments. (2) Flupenthixol especially improves the ability to cope with stress, the ability to achieve something and feeling more relaxed. (3) Subjective quality of life significantly increased with no difference between the groups.

Abstract
Gamma-hydroxybutyric acid is a gamma-aminobutyric acid analogue which can be found in the human brain and is believed to be a neurotransmitter in the central nervous system. In animal experiments as well as in humans gamma-hydroxybutyric acid has been shown to alleviate the symptoms of the alcohol withdrawal syndrome. 299 patients, who were admitted to hospital for reasons primarily unrelated to their alcohol dependence, were treated with gamma-hydroxybutyric acid when symptoms of the alcohol withdrawal syndrome occurred. Gamma-hydroxybutyric acid was usually given at a daily dose of 50 mg/kg in 3 divided doses, the clinical course of the patients was followed for 7 days or until discharge from hospital. Patients were 214 men and 82 women aged 18-87 years. The reasons for admission to hospital were frequently internal diseases, neurological/psychiatric problems, trauma or surgery. At the start of gamma-hydroxybutyric acid treatment, tremor was present in 81% of patients, sweating in 76% and unrest in 92%. Symptoms occurred 1-72 hours after admission. The efficacy of gamma-hydroxybutyric acid to ameliorate or suppress the symptoms of the alcohol withdrawal syndrome was judged to be excellent in 57%, good in 34%, fair in 18%, insufficient in 3% of patients. Drug tolerance was judged to be excellent in 79%, good in 17%, fair in 2% and poor only in 1% of patients. Adverse events were rare and mild. It is concluded that gamma-hydroxybutyric acid is an attractive alternative to tranquilizers in the management of the alcohol withdrawal syndrome in hospital.

Abstract
Information provided by patients about the amounts of alcohol they drink may often be too subjective and therefore unreliable. Because of the possible serious consequences of interactions between alcohol and medication, reliable laboratory test markers for alcohol consumption are needed. Carbohydrate-deficient transferrin (CDT) is at present the best available objective measure of drinking behavior. During a withdrawal trial, 92 alcohol-dependent patients who had been admitted to a hospital in an ethanol-intoxicated state were monitored over the following 28 days by using the percent carbohydrate-deficient transferrin (%CDT of total transferrin) (%CDT) method. At the time of admission, 63% showed elevated %CDT levels. After a subsequent period of abstinence, a decrease in %CDT levels was apparent in four different groups of patients, whereas in two groups, comprising the greatest number of patients, normal %CDT levels were evident after 14 days of abstinence. In patients whose CDT levels were very high at study initiation, it took at least 21 to 28 days--and sometimes longer--for CDT to decrease to the radioimmunoassay (RIA) %CDT test cutoff point of 2.5. In a further study of 56 male alcohol-dependent patients, we measured liver enzyme concentrations, mean corpuscular volume (MCV), and four CDT variants on the first day of evidence of withdrawal syndrome. We found a significant correlation between results on the Munich Alcoholism Test (MALT) and MCV levels; among gamma-glutamyltransferase (GGT), aspartate aminotransferase (AST), and alanine aminotransferase (ALT) levels; and among all four CDT variants. A cluster analysis yielded three clusters: (1) GGT, AST, and ALT levels; (2) MCV levels and MALT results; and (3) all CDT measurement variants. We conclude that these three clusters measure different detriments to the patient and that all available CDT variants are commensurate.

Abstract
The long term course of alcohol dependence often includes one or several relapses, which can be divided into low (< 5 standard drinks = lapse, slip) and high intake of alcohol with loss of control (relapse). The biological etiology of relapse is derived from different phenomena such as alcohol craving, psychosocial reasons, development of withdrawal symptoms, different primary psychiatric diseases and "addiction memory". Moreover, the metabolism of alcohol itself substantially contributes to alcohol dependence. For about 100 years different definitions for subgroups of alcohol dependence have been described, of which the Lesch typology is internationally acknowledged, especially for medical treatment. This typology differentiates between four types of alcohol dependent patients in which prevention and treatment of relapse should be specific to the primary psychiatric disease of the patient and to alcohol related disabilities. The aim is a long term improvement of sobriety rates of alcohol dependent patients as well as quality of life and life expectancy.

Abstract
Flupenthixol, with its broad receptor profile, interacts with a variety of dopamine and serotonin binding sites which are important in the neurobiology of alcohol dependence. Its pharmacology, together with encouraging results from both animal studies and clinical trials with cocaine users, led us to postulate that flupenthixol would significantly prevent relapse in detoxified alcohol-dependent individuals. We conducted a prospective, randomized, double-blind, placebo-controlled, multi-centre trial with two parallel groups and appropriate statistical evaluation. Subjects met criteria for moderate to severe alcohol dependence (DSM-III-R), without any concomitant psychiatric disorder. After complete detoxification, 281 women and men received either 10 mg of flupenthixol decanoate or placebo as i.m. injection every second week for 6 months on an out-patient basis, followed by 6 months of follow-up. Efficacy was based on absolute abstinence, with relapse being defined as consumption of any alcohol after inclusion in the study. In contrast to the hypothesis, flupenthixol did not reduce, but was associated with more, relapses. Though well tolerated, relapse rates after 6 months of treatment were 85.2% (flupenthixol) versus 65.5% (placebo), a highly significant difference from the medication. Flupenthixol was also inferior to placebo with regard to other secondary criteria of efficacy (cumulative abstinence duration, relapse rate after 12 months). These results indicate that a 10 mg dose of flupenthixol decanoate does not have a beneficial effect on abstinence maintenance in alcohol-dependent individuals.

Abstract
Even though alcohol dependence is not often found in the elderly, alcohol consumption and alcohol abuse are both common. As the elderly also often take medication on a regular basis, this group is at particularly high risk for problems resulting from the concurrent use of these substances. Physical changes as a result of the aging process (e.g. reduction of body water, decrease of hepatic blood flow) and alcohol related diseases can influence the pharmacokinetics and pharmacodynamics of both ethanol as well as other drugs. Alcohol dehydrogenase (ADH), acetaldehydede hydrogenase (ALDH) and cytochrome P450 2E1 are the enzymes responsible for the metabolism of ethanol. These enzymes are also the sites of direct pharmacological interaction between ethanol and other drugs, however, altered effects of medication can also be caused by ethanol adding to or reducing the drug's effect. Although some of these effects result from heavy use of alcohol, others can also occur with moderate use. Interactions have most frequently been described for analgetics, psychopharmacologically active drugs, antihistamines, anticoagulants antihypertensive drugs and antibiotics.

Abstract
In an excellent methodological approach, the European acamprosate study project showed that acamprosate increases sobriety times. In one randomized prospective study (n = 260) comparing acamprosate and placebo, with a 1-year treatment phase and 1-year follow-up phase, the authors found that acamprosate is effective only in Lesch type I and type II patients. To investigate the possible influence of diagnostic subgrouping, we applied the Lesch typology in a co-work with the main researchers of the UK study. The UK results concerning acamprosate's effects in the types do not mirror the Vienna results, but the numbers of type I and type II patients, retrospectively found as included in the UK centers, were too small for any conclusions. The distribution of the types points to the fact that too many type III and IV patients had been included to give acamprosate the chance to be effective. Following our typology and also these studies, we developed special treatment approaches. For relapse prevention studies, the cumulative abstinence duration together with the Lesch typology seems to be promising.

Abstract
A considerable number of animal studies on the effects of dopaminergic agents on alcohol intake behavior have been performed. Acute alcohol administration in rats induces dopamine release in the caudate nucleus and in the nucleus accumbens, an effect related among others to reinforcement. It has been repeatedly suggested that D1 and D2 receptor activation mediates reward. As alcohol consumption and dopaminergic transmission seem to have a close relationship, all kinds of dopaminergic agents may be regarded as putative therapeutics for preventing relapse. In a prospective European double-blind multicenter clinical trial, comparing the D1, D2, D3 antagonist flupenthixol and placebo in 281 chronic alcohol-dependent patients (27.4% women), the application of the Lesch typology made an outcome differentiation possible. It could be shown in which patients flupenthixol administration was followed by a significantly higher relapse rate and in which patient groups no differences were found when compared to placebo.

Abstract
Early diagnosis and monitoring of an alcohol relapse in patients after orthotopic liver transplantation for alcoholic cirrhosis is of importance for the long-term outcome. A prospective study of 97 patients who underwent orthotopic liver transplant for alcoholic cirrhosis has been performed. All of the recipients considered for analysis survived for at least 3 months and were under the care of one specialist psychologist. Mean follow-up amounted to 48.5+/-1.4 months. The rates of alcohol relapse at 1 and 3 years after orthotopic liver transplant were 6 and 9%, respectively. Carbohydrate-deficient transferrin is a biological marker for alcohol abuse independently of liver disease and has been used for the first time ever in liver graft recipients. A total of 830 values were included prospectively in the study population. Detection of alcohol relapse had a sensitivity of 92% and a specificity of 98%. Changes in carbohydrate-deficient transferrin levels indicated clandestine and sporadic drinking after transplantation. Furthermore, clinical events were not found to influence carbohydrate-deficient transferrin, either in patients with or without alcoholic relapse. In our opinion, carbohydrate-deficient transferrin is a useful screening marker for alcohol relapse in patients after orthotopic liver transplant for alcoholic cirrhosis, to select those patients who need special attention from the psychologist.

Abstract
OBJECTIVES The aim of this study was to examine the relationship between alcohol consumption and postural control in alcohol-dependent patients. MATERIAL AND METHODS Posturographic measurements were performed in 82 abstinent patients and in 54 healthy controls. The findings in the patients were compared with those in the controls as well as with the daily alcohol consumption, the consumption during 6 months before the admission for alcohol withdrawal therapy and the estimated lifetime alcohol consumption. RESULTS Postural control was impaired in alcohol-dependent patients compared to healthy controls. This impairment was related with the lifetime alcohol consumption, but not with the alcohol consumption per day and prior to admission, respectively. Comparing healthy controls, and alcohol-dependent patients with an estimated lifetime alcohol consumption of < 1000 kg and > or = 1000 kg revealed a significant increase in 6 of 8 sway parameters. Furthermore, the lifetime alcohol consumption increased significantly from patients with normal posturographic and clinical findings to those with abnormalities in both examinations. CONCLUSION This study suggests that postural imbalance in abstinent alcohol-dependent patients is related to the lifetime alcohol consumption.

Abstract
BACKGROUND Hepatitis G (GBV-C/HGV) is an RNA-virus belonging to the flavivirus family and is capable of inducing hepatitis in rare cases. Its importance as a co-factor in the pathogenesis of liver disease needs to be clarified. AIMS To determine the prevalence of HGV in chronic alcoholics with and without liver cirrhosis. PATIENTS 86 alcoholics, 44 with liver cirrhosis and 42 without liver cirrhosis, were investigated; 93 healthy individuals served as controls. METHODS Serum was tested for GBV-C/HGV-RNA by reverse-transcription polymerase chain reaction (RT-PCR) and for anti-E2, a marker of resolved GBV-C/HGV infection, by ELISA. GBV-C/HGV-RNA positive samples were sequenced and the GBV-C/HGV subtype determined. RESULTS Eight out of 86 (9.3%) alcoholics were GBV-C/HGV-RNA positive, as compared to 2 out of 93 (2.2%) healthy controls (n. s.). Twenty-one (24.4%) alcoholics had anti-E2 in serum, whereas this antibody was found in 12 (12.9%) healthy persons only (n. s.). However, significantly more alcoholic patients (33.7%) than healthy controls (15.1%) had past or present contact with GBV-C/HGV (p = 0.006). 11.4% of alcoholic patients with liver cirrhosis and 7.1% of alcoholic patients without liver cirrhosis showed GBV-C/HGV-RNA. 34.1% of alcoholic patients with liver cirrhosis and 16.6% of alcoholic patients without liver cirrhosis had anti-E2. Among the 44 patients with liver cirrhosis, 8 out of 11 (72.7%) patients with variceal bleeding, but only 11 of 33 patients without bleeding had contact with GBV-C/HGV (p = 0.05). Seven out of 8 GBV-C/HGV-RNA positive alcoholics had genotype 2a, 1 had type 1a of GBV-C/HGV. CONCLUSION Alcoholic patients have a significantly higher contact rate with GBV-C/HGV as compared to healthy controls. Alcoholics with liver cirrhosis tend to be more frequently infected than alcoholic patients without liver cirrhosis. A previous variceal bleeding episode is significantly associated with GBV-C/HGV infection.

Abstract
Mnestic disturbances in alcoholics may be related to cholinergic deficiency as well as to central nervous system inactivation. After instillation of tropicamide, cholinergic receptors are blocked and pupillary dilatation occurs. It is assumed that the more severe the cognitive deterioration, the wider the pupillary dilatation. Pupillary oscillations reflect central activation. Changes of pupillary diameter after topical instillation of tropicamide and pupillary oscillations were measured in 44 alcohol-dependent patients aged 40-55 years, diagnosed according to the DSM-III-R as severe alcoholics (>7 symptoms), having been abstinent for at least 3 weeks (objectively tested with carbohydrate-deficient transferrin), compared with 18 healthy controls. The pupillary diameter of the left eye was measured eight times within 103 min, as were pupillary oscillations. Using Fourier analysis, the amplitudes of oscillations were measured in five frequency bands and the sum of the frequency bands was calculated. In addition, central activation was measured during a calculation test at 3 and 103 min. The pupillary dilatation of 22% in alcoholics compared to 14% of normal controls after tropicamide raises the question of a cholinergic deficit in alcohol dependence. With regard to basic activation, measured by Fourier analysis of pupillary oscillations, alcoholics demonstrated significantly lower power (sum of the frequency bands) than controls at baseline and at 3, 20, and 40 min (P < 0.01) as well as at 60, 80, 100, and 103 min (P < 0.05). After a cognitive task, a difference between alcoholics and healthy controls was found at 3 min. Alcoholics showed lower basic activation and decreased cognitive activation. By means of cross-validation, a differentiation between alcohol-dependent patients (n = 44 and n = 42 respectively) and normal controls (n = 18) was possible.

Abstract
Several studies have shown that psychiatric disorders are common in nursing homes, but information on the course of psychiatric morbidity shortly after admission is still lacking. Therefore, we interviewed 262 residents of Austrian nursing homes within 2 weeks following admission, and a second time after 6 months. Using the Clinical Interview Schedule and its case criteria, prevalence was 76.3% at admission, and 69.9% 6 months later. In the intervening period, the mortality rate was markedly higher among psychiatric cases, and the incidence of new psychiatric cases (5.9%) was slightly lower than the rate of remission (8.6%). At both assessments, organic mental illness was the most frequent diagnosis. Nursing home residents suffering from psychiatric disorders were treated predominantly by general practitioners applying a psychotropic drug regimen.

Abstract
The tetrahydroisoquinoline alkaloids salsolinol and norsalsolinol were found in human urine samples in concentrations ranging from 0.1 to 29.5 ng/ml. Great interindividual variation was found in urine levels of these alkaloids in a collection of chronic alcoholics and in a group of nonalcoholics. Thus, levels of the individual alkaloids are insufficient markers for distinguishing between alcoholics and nonalcoholics. However, by using the concentration ratio of norsalsolinol and salsolinol, the so-called dopamine-aldehyde adduct ratio (DAAR), significant differences between alcoholics (median 1.3) and nonalcoholics (median 0.6) were detected. This concentration ratio could serve as a marker for the processor state of the dopaminergic system.

Abstract
Cocaine abuse as a risk factor for acute cerebrovascular events has received too little attention, in particular in young patients. Cocaine hydrochloride causes mainly intracerebral and subarachnoidal bleeding, while crack (freebase) causes intracranial hemorrhage and ischemic infarctions with equal frequency. Although no specific antidote is known, an attempt should be made to detect the substance or its metabolites in the urine so as to provide optimal management, and encourage the patient to seek expert counselling.

Abstract
Human urine samples were examined for the occurrence of formaldehyde-derived tetrahydroisoquinolines and tetrahydro-beta-carbolines generated by condensation of the methanol oxidation product with biogenic amines. Positive results were obtained for the tryptamine condensation product 1,2,3,4-tetrahydro-beta-carboline and the serotonine condensation product 6-hydroxy-1,2,3,4-tetrahydro-beta-carboline as well as for the condensation products with tyramine, dopamine, adrenaline and noradrenaline 1,2,3,4-tetrahydroisoquinoline, 6,7-dihydroxy-1,2,3,4-tetrahydroisoquinoline, N-methyl-4,6,7-trihydroxy-1,2,3,4-tetrahydroisoquinoline, 4,6,7-trihydroxy-1,2,3,4-tetrahydroisoquinoline, and the metabolite 6-methoxy-7-hydroxy-1,2,3,4-tetrahydroisoquinoline. Negative results were obtained for N-methyl-1,2,3,4-tetrahydroisoquinoline and 6,7-dimethoxy-1,2,3,4-tetrahydroisoquinoline, N-methyl-1,2,3,4-tetrahydro-beta-carboline, 6-methyl-1,2,3,4-tetrahydro-beta-carboline, and 6-methoxy-1,2,3,4-tetrahydro-beta-carboline in samples of chronic alcoholics as well as in the urine of healthy volunteers. No correlation between alcohol ingestion or state of alcoholization could be demonstrated.

Abstract
A total of 728 patients admitted to the medical, gynaecological and surgical departments of one urban and one rural general hospital in Austria were investigated for psychiatric morbidity. Using the Clinical Interview Schedule and its case criteria, the prevalence of psychiatric morbidity was found to be highest in medical departments (38.2%), followed by surgical departments (32.5%), and lowest in gynaecological departments (20.7%). Among medical and surgical patients, dementia and substance abuse disorders were the most frequent psychiatric categories, while in gynaecological departments neurotic disorders showed the highest frequency. For the sample as a whole, single status (i.e. unmarried, widowed or divorced), lower social class and rural catchment area of the general hospital predicted a high prevalence of psychiatric morbidity in a logistic regression analysis, while complications of childbirth, pregnancy or the puerperium, and diseases of the skin or the musculoskeletal system showed a negative association with psychiatric illness.

Abstract
BACKGROUND About 50% of alcoholic patients relapse within 3 months of treatment. Previous studies have suggested that acamprosate may help to prevent such relapse. The aim of our study was to assess the efficacy and safety of long-term acamprosate treatment in alcohol dependence. METHODS In this multicentre, double-blind, placebo-controlled study, we recruited 455 patients, aged 18-65 years, with chronic or episodic alcohol dependence. Patients were randomly allocated treatment with acamprosate (1998 mg daily for bodyweight > 60 kg; 1332 mg daily for < or = kg) or placebo for 360 days. Patients were assessed on the day treatment started and on days 30, 90, 180, 270, and 360 by interview, self-report, questionnaire, and laboratory screening. Patients were classified as abstinent, relapsing, or non-attending. Time to first treatment failure (relapse or non-attendance) was the primary outcome measure. FINDINGS Seven patients were excluded from the intention-to-treat analysis because they did not attend on the first treatment day and therefore received no medication. The acamprosate (n = 224) and placebo (n = 224) groups were well matched in terms of baseline demographic and alcohol-related variables. 94 acamprosate-treated and 85 placebo-treated patients completed the treatment phase: of those withdrawn, 104 (52 in each group) relapsed, 69 (33 vs 36, respectively) were lost to follow-up, 63 (31 vs 32) refused to continue treatment, 16 (15 vs 11) had concurrent illness, three (two vs one) died, ten (six vs four) had adverse side-effects, one (acamprosate treated) received the wrong medication, and three (placebo treated) were non-compliant. The proportion without treatment failure was higher in the acamprosate than in the placebo group throughout the treatment period (p < 0.001, Mantel-Cox). At the end of treatment, 41 (18.3%) acamprosate-treated and 16 (7.1%) placebo-treated patients had been continuously abstinent (p = 0.007). Mean cumulative abstinence duration was significantly greater in the acamprosate group than in the placebo group (138.8 [SD 137.5] vs 103.8 [119.0] days; p = 0.012). 148 patients (79 acamprosate, 69 placebo) completed 27 months follow-up: 27 (11.9%) acamprosate-treated and 11 (4.9%) placebo-treated patients remained continuously abstinent, and the mean cumulative abstinence duration was 230.8 days (259.1) and 183.0 days (235.2), respectively. Apart from occasional diarrhoea, there was no difference in side-effects between groups. INTERPRETATION Acamprosate is an effective and well-tolerated pharmacological adjunct to psychosocial and behavioural treatment programmes for treatment of alcohol-dependent patients.

Abstract
We investigated %CDT (carbohydrate-deficient transferrin) in 92 ethanol-intoxicated alcohol-dependent patients after consecutive admission to hospital and followed the for 28 days under controlled conditions. At admission, 63% (58 patients) showed elevated CDT (> 2.5%) and 34 patients (37%) had normal CDT levels (< 2.5%). No correlation of the %CDT values to alcohol-related disabilities, severity of the withdrawal syndrome, alcohol-drinking pattern before admission, or several other factors was found. The sensitivity of GGT (gamma-glutamyl transferase) was 58% for the same group of patients. Levels of %CDT decreased during the 28 days following abstinence, whereby we could separate four statistically different groups of "CDT decrease'. In two of these groups, comprising most of the cases studied, normal %CDT levels were reached after 14 days of abstinence. Those patients with %CDT levels exceeding the upper normal level after 14 days of sobriety, showed a decrease during the following 14 days to levels of 2.55-2.61%.

Abstract
We investigated the usefulness of the laboratory marker of alcohol consumption carbohydrate-deficient transferrin (CDT) in 101 consecutively admitted patients in a surgical and internal medical ward of a hospital in a rural wine-growing area. Four major aspects were considered: the influence of liver disease, the method of expression of CDT values (relative % vs absolute units/1), level and pattern of alcohol consumption and comparison with y-glutamyl transferase (GGT). The results show that %CDT is a more valuable discriminating marker of high alcohol consumption than absolute CDT values and its usefulness in this respect is independent of changes in serum total transferrin levels, as in liver disease. Sensitivity and specificity of % CDT were 70 and 98% respectively, compared with 65 and 83% respectively for GGT.

Abstract
This paper reports the results of a 3-week drinking experiment in 51 healthy male subjects, examining the value of %CDT (carbohydrate-deficient transferrin) in the context of different levels of alcohol intake. All healthy persons were urine-tested drug-free and underwent daily breath alcohol tests for the 7 days preceding, and during the whole 3 weeks of, the experiment. Subjects were divided into five groups, consuming different amounts of alcohol daily over a 3-h period in the presence of the investigators. The five groups consisted of 10, 9, 10, 16 and 6 subjects respectively and consumed a daily dose of ethanol of 20, 40, 60, 80 and 80 g respectively for 3 weeks. No significant changes in %CDT were detected in most subjects, even in the 80 g alcohol-consuming groups. The results suggest that CDT is not sensitive for the detection of short-term heavy drinking by healthy subjects.

Abstract
In recent years, the term 'chronic alcoholism' has had a meaning that is more descriptive than diagnostic. Several subtypes of alcoholism have been established and are now a necessary tool for studying therapy outcome. Alcohol-dependent patients can be subtyped based on clearly assigned dimensions (e.g. biological, sociological and psychological disturbances). Craving and the underlying disturbance must be treated. The number of pharmacological agents that may reduce alcohol intake has increased recently. We conducted a prospective long-term study based on four subtypes of alcohol-dependent patients to assess the efficacy of acamprosate. Our findings demonstrate that these patient subtypes are relevant to outcome in trials of pharmacological agents. We strongly recommend subtyping alcohol-dependent subjects in future trials, because the usefulness of effective drugs could be overlooked when they are tested in a heterogeneous population.

Abstract
Specific laboratory tests can be used to identify patients who are alcohol-dependent. The laboratory values of a number of biological 'markers', including carbohydrate-deficient transferrin, are often elevated in cases of chronic and acute alcohol abuse. Trait markers reflect a predisposition for alcoholism; state markers reflect actual alcohol consumption. It has been suggested that state markers can be subdivided into screening and relapse markers, and even further subdivided into pre-relapse markers, i.e. craving markers. We hypothesize that methanol metabolism and the presence of condensation products in the blood may serve as state and pre-relapse markers for alcoholism. Since the sensitivities and specificities of laboratory screening tests vary, and an absolute marker for alcoholism has yet to be identified, research in the area of biological markers for alcoholism should continue.

Abstract
The development of pharmacological agents in treating alcoholism represents one of many different ways to suppress alcohol intake. Regarding the hypothetical involvement of different neurochemical systems in "alcohol craving", specific substances have been examined in animals models (especially rats) and increasingly in man. Promising results in reducing "alcohol craving" were described in the use of different kinds of chemical substances. "Craving" therefore can hardly be explained on the basis of a deficit in only one neurochemical (neurotransmitter) system. This conclusion is supported by the data. The efficiacy of many anti-craving substances described in smaller studies must first be confirmed in clinical studies on a wider scale.

Abstract
72% of a collective of chronic alcoholics (DSM-III-R, ICD 9), who were admitted under the influence of alcohol in order to undergo alcohol withdrawal, showed a serum methanol concentration (SMC) above 10 mg/l. This level is usually considered to be the one for the detection of regular alcohol consumption. The SMC values were considerably higher in cases where alcoholic beverages with a higher methanol content were consumed rather than the ones lower in methanol. In the majority of patients a decrease of the methanol concentration could only be detected once an individually varying limit concentration of ethanol (0-0.62 g/kg) was reached. There were, however, a few exceptions where the elimination of methanol independent from the ethanol concentration could be seen. Contrasting the general collective, these 'ethanol independent' methanol eliminators showed a much higher serum level of ethanol and methanol at the time of admission. As a sign of addiction, all patients showed increased beta 60 values for ethanol and preferred high proof beverages, which at the same time have high methanol contents.
