RESUMEN
OBJECTIVES: To compare the prognosis of subacromial impingement (SAI) stage II treated conservatively or with subacromial decompression. METHODS: A follow-up study after 4-8 years in a randomized controlled trial (RCT) with 90 adult cases with SAI treated in a Danish hospital from 1996 to 2000 with graded physiotherapy and exercises or arthroscopic subacromial decompression. Outcomes were proportion of time per year with income transfers (indexed 0-1), including total transfers (marginalization), sick leave and disability pension obtained from the registry at the Ministry of Work. Self-reported function, working capability, employment status and global improvement were obtained by questionnaire in September 2004. The main outcomes are given as differences in development from baseline. RESULTS: Seventy-nine (88%) responded to the questionnaire and registry data were obtained from 81. After 1 year the marginalization index increased by 0.45 [95% confidence interval (CI) 0.35-0.56] for surgery and 0.25 (0.16-0.34) for physiotherapy. Cases undergoing surgery also tended to have more sick payments during the first year, but the difference was not significant. Four years after inclusion, changes in indices did not differ between treatment groups. Self-reported outcomes after 4-8 years did not differ between treatment groups. CONCLUSION: The results of surgical decompression were equal to those of conservative treatment, and the surgery group had more income transferrals during the first year of follow-up.

OBJECTIVES: To compare the effect of graded physiotherapeutic training of the rotator cuff versus arthroscopic subacromial decompression in patients with subacromial impingement. METHODS: Randomised controlled trial with 12 months' follow up in a hospital setting. Ninety consecutive patients aged 18 to 55 years were enrolled. Symptom duration was between six months and three years. All fulfilled a set of diagnostic criteria for rotator cuff disease, including a positive impingement sign. Patients were randomised either to arthroscopic subacromial decompression, or to physiotherapy with exercises aiming at strengthening the stabilisers and decompressors of the shoulder. Outcome was shoulder function as measured by the Constant score and a pain and dysfunction score. "Intention to treat" analysis was used, with comparison of means and control of confounding variables by general equation estimation analysis. RESULTS: Of 90 patients enrolled, 84 completed follow up (41 in the surgery group, 43 in the training group). The mean Constant score at baseline was 34.8 in the training group and 33.7 in the surgery group. After 12 months the mean scores improved to 57.0 and 52.7, respectively, the difference being non-significant. No group differences in mean pain and dysfunction score improvement were found. CONCLUSIONS: Surgical treatment of rotator cuff syndrome with subacromial impingement was not superior to physiotherapy with training. Further studies are needed to qualify treatment choice decisions, and it is recommended that samples are stratified according to disability level.

OBJECTIVES: To determine whether minimal intervention by occupational specialists involving information about the disorder, encouragement to stay active and instruction in graded self-performed exercises could enhance the prognosis of lateral epicondylitis compared with the treatment usually given in general practice, to quantify workplace factors associated with the prognosis, and to consider treatments given in general practice. METHODS: A randomized controlled trial was performed in a cohort of 266 consecutive new cases of lateral epicondylitis diagnosed in general practice. Workplace factors were assessed with questionnaires at the time of inclusion, and patients completed follow-ups at 3, 6 and 12 months. Status at 1 yr was assessed as overall improvement and pain reduction compared with the time of diagnosis. General practitioners (GPs) registered the treatments given for both cases and controls during follow-up. Numbers of contacts with GPs and physiotherapists were obtained from the National Health Insurance registry. Prognostic factors were analysed by multiple logistic regression analysis. RESULTS: After 1 yr, 83% of cases showed improvement in the condition, but the intervention was found to have had no advantage. Poor overall improvement was associated with employment in manual jobs [odds ratio (OR) 3.0, 95% confidence interval (CI) 1.0-8.7], a high level of physical strain at work (OR 8.5, CI 1.0-74.7) and a high level of pain at baseline (OR 2.3, CI 1.0-5.3). Pain reduction less than 50% was associated with manual jobs (OR 2.3, CI 1.1-5.1), high physical strain at work (OR 3.6, CI 1.0-12.9), high baseline distress (OR 1.9, CI 1.0-4.0) and tennis elbow on the dominant side (OR 3.1, CI 1.4-6.8). The intervention group received less treatment and fewer treatment modalities, but the intervention was not followed by a reduction in the number of visits to GPs and physiotherapist clinics during 12 months of follow-up. CONCLUSIONS: Poor prognosis at 1 yr of follow-up for lateral epicondylitis was related to manual work and high baseline pain, whilst no relation was found between the type of medical treatment given/chosen and prognosis. This may have implications for the future management of lateral epicondylitis in terms of a greater focus on interaction with the workplace regarding job modification to reduce physical demands during recovery.

AIMS: To assess the importance of physical and psychosocial risk factors for lateral epicondylitis (tennis elbow). METHODS: Case-referent study of 267 new cases of tennis elbow and 388 referents from the background population enrolled from general practices in Ringkjoebing County, Denmark. RESULTS: Manual job tasks were associated with tennis elbow (odds ratio (OR) 3.1, 95% confidence interval (CI) 1.9 to 5.1). The self reported physical risk factors "posture" and "forceful work" were related to tennis elbow. Among women, work involving performing repeated movements of the arms was related to tennis elbow (OR 3.7, CI 1.7 to 8.3). Among men, work with precision demanding movements was related to tennis elbow (OR 5.2, CI 1.5 to 17.9). Among both males and females, the results for work with hand held vibrating tools were inconsistent, partly because of few exposed subjects. A physical strain index was established based on posture, repetition, and force. The adjusted ORs for tennis elbow at low, medium, and high strain were 1.4 (CI 0.8 to 2.7), 2.0 (CI 1.1 to 3.7), and 4.4 (CI 2.3 to 8.7). Low social support at work, adjusted for physical strain, was a risk factor among women (OR 2.4, CI 1.3 to 4.6). CONCLUSION: Results indicate that being a new case of tennis elbow is associated with non-neutral postures of hands and arms, use of heavy hand held tools, and high physical strain measured as a combination of forceful work, non-neutral posture of hands and arms, and repetition. Furthermore, tennis elbow among women was associated with low social support at work. The results for precision demanding movements and for vibration were less consistent.

This article describes a cluster of epoxy related contact dermatitis in a glassfibre reinforcement plant, using mostly preimpregnated epoxylaminate (Pre-Preg), but also fluid epoxy-products. An occupational medical and dermatological examination revealed nine of 26 cases as allergic contact eczema, 14 as toxic epoxyrelated eczema and three cases of other non-occupationally related skin diseases. The plant uses seven different epoxyresins with 15 epoxyhardeners. Preventive measures were gradually improved, but even then it was difficult to rule the production into safe procedures with this potent allergen used in large scale production of windmill wings.
