[Self-training versus conventional physiotherapy in subacromial impingement syndrome].

AIM: This prospective, randomized study was aimed to compare the effect of a standardized self-training versus standard physiotherapist-supervised exercises in the non-operative treatment of shoulder impingement syndrome types Neer I and II. METHOD: 40 patients with subacromial impingement I/II were randomized to two groups. Group 1 performed a mostly isometric self-training after instruction by a physiotherapist, group 2 received prescriptions for physiotherapy and "strengthening exercises for the rotator cuff". Follow up was performed after 6 and 12 weeks with the use of the constant score (unpondered). Patient satisfaction with the treatment was controlled by VAS (1 - 6). RESULT: After 12 weeks, patients of group 1 had performed the exercises 5 x/week for 15 minutes. Patients of group 2 had received 30 sessions in average. Patients of group 1 improved from a mean of 59 points (39.5 - 86) to a mean of 68 points (37 - 88) after 6 and 75 points (65 - 90) after 12 weeks. Patients of group 2 improved from 60.5 points (41 - 83) to 67 points (39.5 - 92) and 72 points (43 - 93), respectively. Patient satisfaction was higher in the self-training group (1.9 : 2.8). CONCLUSION: Strengthening of the centering muscles around the humeral head leads to good results in the non-operative treatment of subacromial impingement. Self-training after instruction showed no difference to physiotherapist-supervised exercises in the non-operative treatment of subacromial impingement.

[Is running associated with premature degenerative arthritis of the hip? A systematic review].

AIM: The study was performed to investigated correlations between running and degenerative arthritis of the hip, according to the principles of evidence-based medicine. METHOD: The database Medline, the Cochrane Library, the centre for Evidence Based Medicine in Oxford and the sports science database Spolit, Spofor and Spowis were scanned systematically for the keywords "arthritis, osteoarthritis, degenerative, hip, sports, running, jogging, walking". RESULTS: 10 retrospective case control studies and 3 prospective studies were included for further analysis. The clinical examinations reported in the prospective studies did not reveal a significant difference between runners and non-runners. In one study a slightly increased risk for signs of arthritis at the X-ray was found in runners below 50 years with a very high mileage. No increased risk for degenerative arthritis was reported in most of the retrospective studies. A few authors of retrospective studies reported a slightly to moderately increased risk. The pooled estimate of the included studies showed a slightly increased risk for degenerative arthritis in runners (pooled OR 1.24 95 % CI 0.87-1.85). However, the increased risk did not reach a level of statistical significance. The graphic analysis of the data with the technique of the funnel plot gives an OR of 1.04. CONCLUSION: There is no evidence that running is associated with an increased risk for degenerative arthritis of the hip. There is no evidence for a different risk in men and women.

[Osteochondral lesions of the talus -- indications for MRI with a contrast agent].

AIM: This study aims to establish the indication for a pre- and postoperative MRI examination with an intravenous contrast agent in patients with an osteochondral lesion of the talus. METHODS: 20 patients with an osteochondral lesion of the talus in the different stages according to DiPaola were prospectively examined preoperatively and 6 months postoperatively by an MRI investigation with an i. v. contrast agent. The Weber ankle score was determined pre- and postoperatively. A correlation was calculated between MRI and arthroscopic findings of an osteochondral lesion (Spearman-rho). RESULTS: There was a significant correlation among the radiological, the MRI and the arthroscopically determined locations. With regard to staging only 12 out of 20 lesions were staged correctly by MRI using arthroscopy as a gold standard. Due to metal artifacts and morphological changes the postoperative MRI could not be used for staging. CONCLUSION: A preoperative MRI investigation is indicated in patients with ankle pain of unknown origin, a normal radiograph and a suspected osteochondral lesion of the talus. MRI is not indicated to determine the localization and the stage of an osteochondral lesion. A postoperative MRI is only necessary for the exclusion of a secondary pathology.

Taenia saginata cysticercosis: a comparison of routine meat inspection and carcase dissection results in calves.

Seventy-nine calves aged between two and 12 months, originating from a known Taenia saginata endemic area, were slaughtered and the carcases subjected to routine meat inspection and afterwards dissected and sliced. At dissection 75.9 per cent were found infected. However, only 38.3 per cent of the infected carcases were detected at meat inspection. Of these, 21.7 per cent had cysts in the triceps muscle only. During slicing 34 out of 60 infected animals (56.7 per cent) were negative for cysts at the so-called predilection sites--muscles of mastication, tongue, heart, oesophagus and diaphragm.

[Histomorphometric contribution to W. Beier's exponent of the aging function].

We determined aging changes of the nucleus-cytoplasm-relation in the epithelium of the epiglottis and intestine of human beings and rats. The results were compared with data about the proliferation of connective tissue and the decrease of muscle cells in the wall of the intestine and in the ciliary muscle. We adapted exponential functions to the measured results. For comparing the several equations and the derivable aging velocities, the nucleus-cytoplasm-relation must be transformed into nucleus volume rate of the total cell volume. Similarities in the decrease of the aging speed in the course of life and in the value of the exponent of the aging function by W. Beier (approximately equal to 0,03) were demonstrated.
