Reliability of the Columbia scale for assessing signs of Parkinson's disease.

Inter- and intrarater reliability in scoring the signs of Parkinson's disease using the original Columbia scale and a modified version of this, the Sydney scale, were assessed in five neurologists participating in a long-term study of Parkinson's disease. Scoring was done on video recordings of 41 patients whose disability ranged from mild to severe. Although all the neurologists were familiar with the scales and had received training designed to produce uniformity of scoring, interrater reliability was poor. The mean score for the Columbia scale varied from 18.6 to 30 and for the Sydney scale from 15.2 to 23.2. By contrast, intrarater reliability was good. This study highlights the limitations of clinical rating scales in Parkinson's disease when more than one rater is used. In designing clinical trials, every effort should be made to ensure that the same patient is always assessed by the same rater.

A randomised cross-over trial of antiemetic therapy for platinum-based chemotherapy. Improved control with an intensive multiagent regimen.

In a partially blinded randomised cross-over trial, 78 patients receiving cisplatinum based chemotherapy were assigned to receive two forms of antiemetic therapy: SAD, a regimen composed of serenace (haloperidol), ativan (lorazepam), and dexamethasone followed by low dose maxolon (metoclopramide) and STADMAX, a regimen composed of scopolamine (hyoscine), tavegyl (clemastine), ativan, dexamethasone and high dose maxolon. Each antiemetic regimen was given in random order, with the first and second cycles of cytotoxic chemotherapy. 66 (85%) patients completed both cycles of antiemetic therapy and were available for the cross-over comparison. Significantly less acute vomiting, as assessed by nurse observer (P < 0.0001), and less delayed vomiting, as assessed by patient diary (P = 0.03), were seen with STADMAX. In the first 18 h, complete control of vomiting (no episodes) was achieved in 30 (45%) patients with STADMAX compared with 10 (15%) receiving SAD. Overall, major control of emesis (< or = 2 episodes) was achieved in 56 (85%) patients with STADMAX compared with 35 (53%) receiving SAD. Vomiting was also better controlled on STADMAX in the week after this initial 18 hour period based on the 7 day patient diary with no vomiting episodes in 18/65 (28%) on STADMAX vs. 13/65 (20%) on SAD. However, no significant differences in appetite, nausea or vomiting were found when based on linear analogue self assessment (LASA) scales recorded by patients. Significant differences in side effects of the two antiemetic regimens were noted on LASA scales with more dry mouth (P = 0.01), blurred vision (P = 0.03) and diarrhoea (P = 0.04) associated with STADMAX and more restlessness (P = 0.002) associated with SAD. Significantly, no episodes of dystonic reactions were seen among patients on either regimen. In the 68 patients who completed both cycles and were in a position to express a preference, 46 (68%) preferred STADMAX compared with only 20 (29%) who preferred SAD (P = 0.001), while 2 patients expressed no preference. It is concluded that STADMAX is the preferred regimen to SAD for the control of cisplatinum-related emesis. It has a role, both where specific serotonin 3 antagonists are not available and as a model for building more effective combinations where these agents are available.

The epidemiology of incomplete childhood immunization: an analysis of reported immunization status in outer western Sydney.

We surveyed parents of children enrolled in kindergarten in 1992 in outer western Sydney and the Blue Mountains. Using parents' reports, we determined the prevalence of immunization uptake for children starting school, compared the prevalence of immunization uptake among Catholic, government and independent schools, and identified immunization providers. We also documented parental beliefs about immunization and their influence on immunization status, and identified risk factors for incomplete immunization. Nearly 89% of children were reported to be fully immunized. Immunization status did not vary significantly among the different types of school. General practitioners provided 84% of all immunizations and local councils 11%. Incomplete immunization was associated with more negative beliefs in immunization, with post-secondary education and with families who do not speak English at home. Reminder letters had little effect on immunization status.
