Most patients with high alcohol consumption but without severe liver disease do not have an AST/ALT ratio above 1. High AST/ALT ratio suggests advanced alcoholic liver disease.
This study supports the effect of naltrexone in outpatient treatment of alcohol dependence and suggests that a beneficial interaction effect with CBT can be expected.
Thrombocytopenia is more frequent in patients who develop severe AWS (DT or seizures). The findings, including the high NPV of thrombocytopenia, must be interpreted with caution due to the small number of patients who developed AWS. Further studies replicating the present finding are therefore needed before the clinical usefulness can be considered.
Eleven patients with severe Parkinson's disease and on-off-phenomena were included in a controlled double-blind study on the effect of electroconvulsive therapy (ECT). Pharmacological treatment was optimally adjusted before the trial. The severity of extrapyramidal symptoms was measured before, during and after the treatment. The patients were randomly allocated into one group, receiving active ECT and another, receiving sham treatment. The patients given active ECT showed significantly (P less than 0.05) prolonged duration of "on"-phases after ECT, in comparison to the sham-treated group. When collecting data from the controlled part of the study and the subsequent with open administration of ECT, the treatment was in addition found to significantly decrease the time and number of steps required to walk 10 meters. Moreover it reduced the severity of parkinsonian symptoms according to the Webster scale. The improvement induced by ECT was generally short-lasting. Lumbar punctures were performed before and after ECT. The concentrations of monoamine metabolites in cerebrospinal fluid were not affected by the treatment. The results indicate that ECT has an antiparkinsonian effect which probably is mediated via changed responsiveness of dopamine receptors and that further improvement is possible in patients, therapy resistant to the presently available medication.
The dexamethasone suppression test (DST) was performed on 21 patients with dementia of the Alzheimer type (DAT), 11 patients with multi-infarct dementia (MI) and 14 healthy controls. Twelve of the DAT patients and eight of the MI patients showed abnormal lack of suppression, compared with just one member of the control group. Abnormal DST was related to dementia as such and not to age or depression, or to levels of CSF monoamine metabolites. Basal serum prolactin concentrations were not increased.
Consequently, the findings in this study lend further support to the notion of an association between the DRD2 A1 allele and alcohol-dependence, although the effect size of the DRD2 A1 allele is small.
The present study is, to our knowledge, the first report of an association between the TaqI A1 allele and a substantially increased relapse rate. It should be emphasized that the number of subjects is relatively small, and this investigation should therefore be considered as a pilot study.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
