Tiapride and chlordiazepoxide in acute alcohol withdrawal. A controlled clinical trial.

The efficacy of chlordiazepoxide and tiapride in the management of acute alcohol withdrawal syndrome was compared in a randomized, parallel-group, double-blind trial. The mean daily dose for both preparations on the first two days was four capsules, i.e., 200 mg for chlordiazepoxide and 400 mg for tiapride. Thereafter the patients were treated according to the relief of symptoms obtained. The treatment periods lasted 3-5 days. Both drugs effectively alleviated alcohol withdrawal symptoms, especially anxiety, fear, hallucinations, insomnia, sweating, tremor, abdominal pain and vertigo. Seventy percent of the patients in the chlordiazepoxide and 42% in the tiapride group considered the drug effective. The difference was statistically significant in favour of chlordiazepoxide (p less than 0.05). Tiapride is an alternative drug in the treatment of this condition, if benzodiazepines are to be avoided.

A study of attempted suicides in urban versus rural areas, with a follow-up.

The group of subjects consisted of 44 patients (attempters) who were admitted to hospital for treatment because of attempted suicide during a 3-month period in Norther Savo (in Eastern Finland), another 44 patients (non-attempters) admitted to hospital in the same period for other reasons serving as controls. The number of women was the same in both groups, and so was, in consequence, the number of men. The study compared the attempters with the non-attempters and, in addition, the patients coming from urban areas with those coming from rural areas, the ratio of the urban to the rural patients being the same in both groups. The study was based on personal psychiatric interviews with the patients, which took place in each case both immediately following the patient's admission and precisely 3 months afterwards. The results showed that schizophrenia was significantly more frequent in the rural than in the urban attempter group. By contrast, alcoholism and alcohol abuse were more frequent in the urban than in the rural attempter group. Compared with the urban patients, the rural patients tended to be physically more seriously desordered. Poisoning by drugs was a significantly more frequent means of attempted suicide in the urban than in th rural group. The patients in the latter group, again, had resorted oftener to the so-called "active" methods of attempted suicide. Of the attempters, 25% attempted suicide anew during the 3-month follow-up period, the corresponding figure for the non-attempter group being only 6%. During the follow-up period, a greater number of suicidal attempts was made by the patients in the rural group than by those in the urban group, and, as regards the intent to succeed, the attempts of the former were more serious than those of the latter. The so-called "active" methods were used more often by rural than by urban patients also during the follow-up period. All in all, the self-destructive behaviour exhibited during the follow-up period was graver in the rural than in the urban group.

Cerebral benzodiazepine receptor binding and distribution in generalized anxiety disorder: a fractal analysis.

Data obtained from animal and human brain imaging studies indicate that frontal cortex and medial temporal lobe are involved in experiencing and controlling fear and anxiety. We tested the hypothesis that benzodiazepine receptor binding is decreased in the left temporal pole and increased in the right prefrontal area among patients suffering from anxiety. We studied 10 drug-naive female patients with generalized anxiety disorder (GAD) and 10 age- and gender-matched healthy controls with MRI and with SPET by using a new (123)I-labelled specific benzodiazepine receptor radioligand, NNC 13-8241. Blindly analyzed results showed that the benzodiazepine receptor binding of [(123)I]NNC 13-8241 was significantly decreased in the left temporal pole among patients with GAD when compared with age- and sex-matched healthy controls. This hemispheric asymmetry was studied further with a fractal analysis of the SPET images. The fractal dimension of the left hemispheric benzodiazepine receptor binding in patients with GAD was significantly higher than that of controls (1.28 +/- 0.09 and 1.17 +/- 0.07, respectively), whereas the intercept was decreased by 43 +/- 23% reflecting more homogeneous cerebral benzodiazepine receptor density distribution in patients with GAD. The finding is analogous to the decreased heterogeneity of myocardial blood flow observed in patients with ischemic heart disease. The results are consistent with the general hypothesis that high regional heterogeneity of perfusion, metabolism and receptor density is necessary to maintain adaptation ability in the living organism.
