    Objective: The Stroke-Specific Quality of Life Scale (SS-QOL) is a recently developed measure to assess health-related quality of life in stroke patients. The objective of this study was to translate the American version of the SS-QOL and examine the validity of the German proxy version, in both ischemic and hemorrhagic stroke survivors. Methods: The translation was conducted according to published guidelines. The validation was performed in consecutive adult stroke survivors. Data were obtained 1 year after discharge. To examine the dimensionality of the SS-QOL, factor analyses were conducted. The validity was examined by the associations of the subscales with the Functional Independence Measure and Short Form 36. Results: The literal translation revealed no major changes between the American and the German versions of the SS-QOL. Three hundred seven stroke survivors were included in the study. Unlike the 1st validation study, most of the variance could be explained by 8 instead of 12 factors; therefore, the 8-factor solution was further examined. The validity of the SS-QOL total score and “observable” scales such as “activities” was shown. Conclusions. For the German proxy version of the SS-QOL, an 8-factor solution was found to be the most appropriate. The psychometric properties of these 8 subscales were good or excellent with respect to internal consistency. The validity of the total score was shown, but some subscales(energy, mood, and thinking) failed the hypothesized associations. Therefore, the SS-QOL needs to be further explored in other settings and populations

    Efficacy of rehabilitation interventions in rheumatic conditions

    All industrialized nations are facing a crisis in health care financing. Rising expectations coupled with increasing specialization and technologic capacities have forced health care payers to examine their assumptions and to seek data on the outcomes of medical interventions. Clinical investigators who have been taught to use randomized controlled trials that evaluate efficacy under experimental conditions have been redirected toward studies that can help answer health policy questions. Such studies examine the effectiveness of interventions in more realistic settings on a richer array of patient-centered outcomes such as function and consider cost effectiveness and relative cost effectiveness. Rehabilitation interventions, which are by and large pragmatic, have never had a strong scientific basis grounded in controlled trials, and this lack of evidence has put tremendous pressure on clinicians to justify their practices. In this article, we review the recent literature on effectiveness of rehabilitation interventions in rheumatic disorders

    Is Misoprostol Cost-effective in the Prevention of Nonsteroidal Anti-inflammatory Drug—Induced Gastropathy in Patients With Chronic Arthritis?

    Whether misoprostol, a synthetic prostaglandin E1 analogue, should be routinely prescribed along with nonsteriodal anti-inflammatory drugs (NSAIDS) to prevent gastric damage is of great clinical importance and has profound cost implications. No consensus exists on whether misoprostol cotherapy results in a cost-saving, is cost-effective, or is costly. The different conclusions reached by five economic evaluations of misoprostol can be explained solely by the assumed absolute risk reduction of symptomatic ulcer, which was more than seven times greater in the studies that concluded that misoprostol was cost-effective than in a study that concluded misoprostol to be costly. Since no study has directly shown the effectiveness of misoprostol cotherapy in preventing clinically significant ulcer disease (ie, hemorrhage and preforation), it is impossible to judge which assumptions are most appropriate. The absence of firm data on the rate of NSAID-induced gastric ulcers reduced by misoprostol makes it impossible to conclude whether it is cost-effective in patients with chronic arthritis who use NSAIDS

    Rehabilitation: The health strategy of the 21st century.

    There is strong evidence that population ageing and the epidemiological transition to a higher incidence of chronic, non-communicable diseases will continue to profoundly impact societies worldwide, putting more pressure on healthcare systems to respond to the needs of the people they serve. These trends argue for the need to address what matters to people about their health: limitations in their functioning that affect their day-to-day actions and goals in life. From its inception, rehabilitation, 1 of the 4 health strategies identified in the Declaration of Alma Ata in 1978, has had functioning as its outcome of interest. Its practitioners are from fields that include physical and rehabilitation medicine, occupational therapy, physiotherapy, speech and language therapy, orthotics and prosthetics, psychology, and evaluators of functioning interventions, including assistive technologies. Demographic and epidemiological trends suggest that the key indicators of the health of populations will be not merely mortality and morbidity, but functioning as well. This, in turn, suggests that the primary focus of healthcare will need to respond to actual healthcare demands generated by the need for long-term management of chronic conditions, including, in particular, the scaling up and strengthening of rehabilitation. This is the case for thinking that rehabilitation will become the key health strategy of the 21st century

    Developing Human Functioning and Rehabilitation Research from the comprehensive perspective.

    Get PDF
    With the International Classification of Functioning, Disability and Health (ICF) the World Health Organization (WHO) has prepared the ground for a comprehensive understanding of Human Functioning and Rehabilitation Research, integrating the biomedical perspective on impairment with the social model of disability. This poses a number of old and new challenges regarding the enhancement of adequate research capacity. Here we will summarize approaches to address these challenges with respect to 3 areas: the organization of Human Functioning and Rehabilitation Research into distinct scientific fields, the development of suitable academic training programmes and the building of university centres and collaboration networks

    Ankylosing spondylitis and sarcoidosis — Coincidence or association?

    Get PDF
    We report a 25-year-old woman presenting with sarcoidosis and bilateral sacroiliitis. Her sarcoidosis related symptoms (malaise, cough and dyspnoea) improved dramatically under treatment with steroids but severe back pain persisted. Only seven similar cases have been described over the last 40 years and the question of a possible association between the two diseases has been raised. However, prevalence data from the literature and the apparent lack of genetic links are better arguments for coincidence than for association

    Efficacy and Safety Of Radiation Synovectomy with Yttrium-90

    In this long term retrospective study of radiation synovectomy with Yttrium-90 (Y90), we evaluated the results of 164 applications in 82 patients with RA, OA with synovitis, ankylosing spondylitis and psoriatic arthritis. Radiation synovectomy with Y90 has an overall success rate of approximately 50% and is therefore an effective alternative to surgical synovectomy in chronic synovitis which fails to respond to conservative treatment. Elbow and knee responded significantly better than shoulder and ankle joints. Patients with radiological stages from 0 to 2 showed a significantly better success rate than those with stage 3 changes. In responders, repeat therapy for recurrence of symptoms or treatment of a symptomatic corresponding symmetrical joint is advisable. Repeat therapy in a previous non-responder is associated with an unacceptably high failure rate. Therefore, when a joint fails to respond after 6 months, arthroscopy should be performed to evaluate further treatment procedures. A successful result was found in only 11 of 25 joints treated with arthroscopic synovectomy followed by radiation synovectomy within 2 weeks, indicating no benefit of this combination
