"Quality of life" (QOL) measurement reflects the impact of a disease on the daily life of a patient, and this can be used as an outcome measure in clinical trials. QOL measurements are rarely used in patients with neuromuscular disease. The aim of this study was to determine whether QOL is reduced in chronic polyneuropathy, whether there is a relationship between QOL and objective measures of disease severity, and whether measuring QOL is a useful addition to the assessment of severity of polyneuropathy. ⋯ Patients with both low motor and low sensory scores rated lower in physical and emotional areas than less impaired patients. A low Rankin score was related only to physical domains. We conclude that in patients with chronic axonal polyneuropathy the severity of disease can be assessed with a general QOL instrument, and that this provides additional information, particularly on areas related to emotional and social functioning.

Meta AnalysisPlacebo effect in the acute treatment of migraine: subcutaneous placebos are better than oral placebos.
We carried out a meta-analysis of 22 trials to determine the comparative placebo effect of (a) subcutaneous vs. oral and (b) in-hospital vs. at-home administration in the treatment of migraine. The headache relief rates were combined from the placebo arms of these randomised clinical trials assessing the value of sumatriptan in acute treatment of migraine. The main outcome measure was the proportion of patients reclassified from severe or moderate headache severity to no or mild headache severity 2 h after the beginning of treatment. ⋯ These findings indicate that subcutaneous administration enhances the placebo effect of acute treatment of migraine. Future trials of antimigraine drugs assessing the relative efficacy of various routes of administration should use a double-dummy technique. The interpreting of placebo-controlled trial results must therefore consider that the effect in the drug arm of the trial depends in part on the route of administration.

ReviewTreatment and outcome of severe intraventricular extension in patients with subarachnoid or intracerebral hemorrhage: a systematic review of the literature.
Severe intraventricular hemorrhage caused by extension from subarachnoid hemorrhage or intracerebral hemorrhage leads to hydrocephalus and often to poor outcome. We conducted a systematic review to compare conservative treatment, extraventricular drainage, and extraventricular drainage combined with fibrinolysis. We carried out a search in Medline of the literature between January 1966 and December 1998 and an additional hand-search from January 1990 to December 1998. ⋯ Outcome is thus poor in patients with intraventricular extension of subarachnoid or intracerebral hemorrhage. This meta-analysis suggests that treatment with ventricular drainage combined with fibrinolytics may improve outcome for such patients, although this impression is derived only from an indirect comparison between observational studies. A randomized clinical trial is warranted.

Development and validation of a short measure of health status for individuals with amyotrophic lateral sclerosis/motor neurone disease: the ALSAQ-40.
In recent years there has been an increased appreciation of the importance of measuring health status from the patient's point of view, but until now no attempt has been made to develop an amyotrophic lateral sclerosis (ALS)-specific health status measure. The development of such an instrument is especially relevant now with the introduction of drugs that prolong life in ALS but limited data is available on the impact such treatments have on quality of life. This paper reports on the development of an ALS-specific measure, the forty item ALS assessment questionnaire (ALSAQ-40). ⋯ Finally in stage 3 the data collected in stage 2 was analysed to areas measured by the instrument and to remove redundant questions. The resulting measure contains forty questions measuring five areas of health status: Eating and Drinking, Communication, ADL/independence, Physical mobility, Emotional Functioning. The measure has high face, internal and construct validity and is likely to prove a useful measure in the evaluation of treatment regimes for ALS/MND.
