Cervical dystonia severity scale reliability study.

Cervical dystonia (CD) is characterized by sustained contractions of the neck musculature, resulting in abnormal head postures. The Cervical Dystonia Severity Scale (CDSS) was developed to provide a reliable measure of treatment response in patients with CD. The CDSS uses a protractor and wall chart to rate the severity of the head's deviation from neutral in each of three planes of motion (rotation, laterocollis, anterocollis/retrocollis), which is then scored in 5 degree intervals (1 degree to 5 degrees deviation = 1; 86 degree to 90 degrees deviation = 18). To test the reliability of the CDSS, four centers, each with two independent examiners, evaluated 42 patients with CD. At each site, each of the two examiners used the CDSS to evaluate the head position of each patient twice, on the same day, for a total of four evaluations. The kappa value for intra-examiner agreement was 0.94 (95% confidence limit of 0.900-0.972), indicating excellent intra-examiner reliability. The kappa value for interexaminer reliability was 0.79 for the first evaluation and 0.86 for the second evaluation (95% confidence limits of 0.668-0.920 and 0.790-0.920) indicating excellent interexaminer reliability. Thus, the CDSS was highly reliable in both intra-examiner and interexaminer scoring comparisons.

A pilot evaluation of the tolerability, safety, and efficacy of tolcapone alone and in combination with oral selegiline in untreated Parkinson's disease patients. Tolcapone De Novo Study Group.

Tolcapone is a potent, reversible catechol-O-methyltransferase (COMT) inhibitor with both peripheral and central activity. It has been demonstrated to improve motor function and allow levodopa dose reductions in Parkinson's disease (PD) patients who are experiencing either a stable response or motor fluctuations while on levodopa/dopa decarboxylase inhibitor therapy. Because striatal dopamine is metabolized by COMT and monoamine oxidase (MAO), central COMT inhibition alone or in combination with MAO inhibition might provide symptomatic benefit for patients not receiving levodopa. We conducted a pilot study to evaluate the tolerability, safety, and efficacy of tolcapone alone and in combination with oral selegiline in early untreated PD patients. Patients were randomized to receive 200 mg tolcapone three times a day or placebo for the 8 weeks of the study. Open-label oral selegiline (5 mg in the morning and midday) was administered to all patients during the second 4 weeks of the study. There was no difference between treatment groups according to the investigator's assessment of tolerability at week 4. Ninety-five percent of tolcapone-treated patients and 98% of placebo-treated patients experienced excellent or good tolerability during the first 4 weeks (95% confidence interval [CI]: -10.3, 5.7; p = 0.57). A decrease in tolerability occurred in the tolcapone group during the second 4 weeks of the study following the addition of selegiline. The most commonly reported side effects were diarrhea (31% tolcapone, 7% placebo), nausea (21% tolcapone, 2% placebo), urine discoloration (12% tolcapone, 0% placebo), dizziness (12% tolcapone, 5% placebo), headaches (12% tolcapone, 10% placebo), and abdominal pain (10% tolcapone, 5% placebo). We did not identify symptomatic benefit associated with tolcapone alone or in combination with oral selegiline in this group of otherwise untreated PD patients.

An open-label study of botulinum toxin A for treatment of tardive dystonia.

Tardive dystonia is a form of tardive dyskinesia for which there is little satisfactory treatment. We reviewed our experience at four movement disorder centers in the treatment of tardive dystonia with botulinum toxin A (BTX-A). Thirty-four patients with relatively localized tardive dystonia unresponsive to oral medications were treated with injections of BTX-A into dystonia muscles. Cervical dystonia was the most frequent manifestation of tardive dystonia in this group of patients. There was marked or moderate improvement in 29 of 34 patients. Eighteen of 24 patients with cervical dystonia showed either marked or moderate improvement. In this retrospective review, BTX-A provided useful symptomatic treatment for localized dystonia in patients with tardive dystonia unresponsive to other treatment. A controlled, prospective trial of BTX-A in tardive dystonia is warranted.
