Ubiquitin pathway: another link in the polyubiquitin chain?

Polyubiquitin has long been recognised as an intracellular signal. It now appears that different lysine linkages between the ubiquitin moieties are recognised as distinct signals and act in different cell processes. The generation of these different polyubiquitin chains may play an important part in the life of a cell.

Disablement following stroke.

PURPOSE: Stroke is the most disabling chronic condition, newly affecting 35000 persons in Canada each year. Because of declining fatality, a growing number of persons will have to cope with stroke-related disability. The purpose of this paper is to describe the disabilities experienced by persons with stroke during the first year and explore the evolution of impairment, disability, handicap and health-related quality of life. SUBJECTS: The data for this paper come from a series of longitudinal and cross-sectional studies, collectively known as the McGill Stroke Rehabilitation Research Program. RESULTS: Within the first week post-stroke, getting out of bed and walking over a short distance, even with assistance, was a strong predictor of discharge home. Most of the improvement in measures of impairment and disability occurred during the first month and, by 3 months, there was still considerable room for improvement in all measures: 85% of persons were still impaired on gait speed, 78% had not reached age-specific norms for upper extremity function, 68% still demonstrated slow physical mobility, 37% needed some assistance with basic activities of daily living and 29% were still impaired on balance. By 1 year, 73% of persons scored the maximum for basic activities of daily living but 51 and 67% of persons reported their physical health and mental health to be lower than expected. Among a hardy group of stroke survivors, still living in the community 1 year post-stroke, the most striking area of difficulty was endurance, as measured by the 6 minute walk test. Those subjects well enough to complete this task (50% of sample) were able to walk, on average, only 250 metres, equivalent to 40% of their predicted ability. This series of snapshots taken at different points in time suggests that much of the improvement in impairment and disability occurs during the first month and then reaches a plateau. Handicap and quality of life continue to be issues later. Rehabilitation strategies need to consider the multifaceted nature of disablement, which in itself changes with time post-stroke.

Heel seats and shoe wear.

Seventy-two children with excessive heel valgus and markedly uneven shoe wear were treated by Helfet heel seats for 18-36 months. Of the 52 children reviewed in this study, 44 had improved shoe wear. Simple heel seats offer economical treatment for children whose foot deformities destroy their shoes.

The use of quality benchmarking in assessing web resources for the dermatology virtual branch library of the National electronic Library for Health (NeLH).

BACKGROUND: In 1998, the U.K. National Health Service Information for Health Strategy proposed the implementation of a National electronic Library for Health to provide clinicians, healthcare managers and planners, patients and the public with easy, round the clock access to high quality, up-to-date electronic information on health and healthcare. The Virtual Branch Libraries are among the most important components of the National electronic Library for Health. They aim at creating online knowledge based communities, each concerned with some specific clinical and other health-related topics. OBJECTIVES: This study is about the envisaged Dermatology Virtual Branch Libraries of the National electronic Library for Health. It aims at selecting suitable dermatology Web resources for inclusion in the forthcoming Virtual Branch Libraries after establishing preliminary quality benchmarking rules for this task. Psoriasis, being a common dermatological condition, has been chosen as a starting point. METHODS: Because quality is a principal concern of the National electronic Library for Health, the study includes a review of the major quality benchmarking systems available today for assessing health-related Web sites. The methodology of developing a quality benchmarking system has been also reviewed. Aided by metasearch Web tools, candidate resources were hand-selected in light of the reviewed benchmarking systems and specific criteria set by the authors. RESULTS: Over 90 professional and patient-oriented Web resources on psoriasis and dermatology in general are suggested for inclusion in the forthcoming Dermatology Virtual Branch Libraries. The idea of an all-in knowledge-hallmarking instrument for the National electronic Library for Health is also proposed based on the reviewed quality benchmarking systems. CONCLUSIONS: Skilled, methodical, organized human reviewing, selection and filtering based on well-defined quality appraisal criteria seems likely to be the key ingredient in the envisaged National electronic Library for Health service. Furthermore, by promoting the application of agreed quality guidelines and codes of ethics by all health information providers and not just within the National electronic Library for Health, the overall quality of the Web will improve with time and the Web will ultimately become a reliable and integral part of the care space.

Disease-modifying antirheumatic drugs in rheumatoid arthritis: current concepts.

Disease-modifying antirheumatic drugs are used in virtually all patients with established rheumatoid arthritis. An increasingly large number of new drugs is now available. Furthermore, old therapies are being used in novel ways. Treatment is now begun earlier and patients are rarely left untreated. This report summarises recent developments regarding the drugs currently in use and those that may be available in the near future.
