The St. Hans Rating Scale (SHRS) is a multidimensional rating scale for the evaluation of neuroleptic-induced hyperkinesia, parkinsonism, akathisia and dystonia. This scale and the Abnormal Involuntary Movement Scale (AIMS) were tested by 7 raters (2 experienced, 2 less experienced and 3 totally inexperienced) in 30 psychiatric patients with tardive dyskinesia (TD). The test was performed 3 times in the same patients: 1) live evaluation during a video recording, 2) evaluation 2 weeks later from the videotape, and 3) evaluation after another 2 weeks from the same videotape. The intrarater reliability was high in the experienced group (0.91-0.96 for SHRS hyperkinesia scale, 0.80-0.84 for AIMS, and 0.82-0.97 for SHRS total parkinsonism). No significant changes occurred from live to video evaluation. The interrater reliability coefficient for the experienced group was also high: 0.89-0.95 for the SHRS hyperkinesia scale, 0.76-0.85 for the AIMS scale and 0.95-0.98 for the SHRS parkinsonism scale. The less experienced and the inexperienced raters had coefficients for intra- and interrater reliability that were 0.10 and 0.20 lower, respectively. The SHRS parkinsonism scale had a high construct validity, as determined by the homogeneity coefficients of Cronbach (0.82) and Loevinger (0.43). The corresponding coefficients for the hyperkinesia scales were low, in agreement with the individual distribution of TD (only about 50% present extremity dyskinesia and less than 25% facial, head and trunk dyskinesia, independent of the severity of the syndrome). Finally, convergent validity was found between the SHRS hyperkinesia scale and AIMS and divergent validity between all of the other scales.(ABSTRACT TRUNCATED AT 250 WORDS)

The aim of this multicenter, randomized, double-blind, 8-week study was to compare the antidepressant efficacy and tolerability of mirtazapine and venlafaxine in the treatment of hospitalized patients with DSM-IV diagnosis of severe depressive episode with melancholic features. Patients with a baseline score of > or = 25 on the 17-item Hamilton Rating Scale for Depression (HAM-D-17) were randomly assigned to receive treatment with either mirtazapine (N = 78, 15-60 mg/day) or venlafaxine (N = 79, 75-375 mg/day, twice a day) in a rapid up-titration schedule. Efficacy was assessed with the Montgomery-Asberg Depression Rating Scale (MADRS), HAM-D-17, and Clinical Global Impression scale, and quality of life was assessed with the Quality of Life, Enjoyment, and Satisfaction Questionnaire and Quality of Life in Depression Scale. Tolerability was assessed with the Utvalg for Kliniske Undersogelser (UKU) side effect scale and by reporting adverse events. Both drugs were effective in reducing overall symptoms of depression, showing substantial reductions in group mean MADRS scores (-20.1 for mirtazapine and -17.5 for venlafaxine) and HAM-D-17 scores (-17.1 for mirtazapine and -14.6 for venlafaxine) at the end of the treatment. Although not statistically significant, at all assessment times higher percentages of patients treated with mirtazapine were classified as responders (> or =50% reduction) on the HAM-D (at endpoint, 62% vs. 52%) and MADRS (at endpoint: 64% vs. 58%). Likewise were the percentages of remitters (HAM-D score < or =7; MADRS score < or =12) also higher in the mirtazapine group. A statistically significant difference favoring mirtazapine was found on the HAM-D Sleep Disturbance factor at all assessment points (p < or = 0.03). Both treatments were well tolerated. Although slightly more subjects treated with mirtazapine reported at least one adverse event, a statistically significantly higher percentage of patients treated with venlafaxine (15.3%) than mirtazapine (5.1%) dropped out because of adverse events (p = 0.037). Quality of life improved in both treatment groups. In this study, treatment with mirtazapine resulted in a trend toward more responders and remitters than treatment with venlafaxine and in significantly fewer dropouts as a result of adverse events.

A double-blind cross-over trial of the effects of baclofen and placebo was carried out in 20 female patients suffering from neuroleptic-induced tardive dyskinesia. After 14 days of treatment 15 patients showed improvement of baclofen, whereas none showed improvement on placebo; baclofen was thus significantly more effective than placebo. Baclofen is a GABA-like drug which passes through the blood-brain barrier and which reduces the neuroleptic-induced increase of dopamine turn-over. In tardive dyskinesia is found dopaminergic hypersensitivity, and baclofen is supposed to exert its action by inhibiting the dopamine activity. Side effects, although temporary, were observed in the form of sedation, muscular hypotonia, dizziness, vomiting, and muscular rigidity. One patient developed a depression. Baclofen or other gabergic drugs used in the treatment of dyskinesias do not increase the dopaminergic hypersensitivity, which is part of the pathogenesis of these conditions; gabergic therapy must therefore be preferred to treatment with dopamine receptor blocking drugs.
