Changes in lymphocyte subpopulations after prolonged exercise.

In order to assess the changes in the cellular immune system, 27 healthy male subjects were selected who participate in leisure-time sports and in whom measurements of the lymphocyte subsets in venous blood were carried out before and after a standardized endurance exercise test (EI, 60 minutes in length, intensity: 63% of maximum performance). The percentages of the following parameters were measured: total T-lymphocytes, B-lymphocytes and O-lymphocytes as well as T4-lymphocytes (helper T-lymphocytes, CD4+) and T8-lymphocytes (cytotoxic/suppressor T-lymphocytes, CD8+). In a subgroup consisting of 8 subjects, the parameters indicated above were measured again 24 hours following E. In order to check the reproducibility of the findings, the endurance exercise test was repeated 21/2 weeks later (EII).

[Can ultrasonography be used to measure torsion angle of the humerus? Comparison of ultrasonographic, computerized tomographic and anthropometric methods].

Sonographic measurements on 40 cadavaric humeri of the angle of torsion according to Harland had been performed. The results were referred to different computertomographic and anthropometric methods. Sonographic measurements proofed to be accurate and were easily reproducible. Comparing sonographically detected angles with the anthropometric results there was shown a mean difference of 28.9 degrees +/- 7.8 degrees. We conclude that sonography is able to give accurate and reproducible results that do not exactly reflect the angle of torsion.

Noninvasive diagnosis of cruciate ligament damage with particular reference to computed tomography with arthrography.

Computed tomography (CT) with arthrography, a method not requiring anesthesia, has worked well in cruciate ligament damage diagnosis, particularly in the detection of PCL damage and in differentiation between ACL and PCL lesions. Evidence has been produced of its superior accuracy by comparison, in the study of 40 patients, among clinical findings, findings obtained from initial radiography, and diagnostic data produced by CT alone. Reference is also made to false interpretations in the context of clinical examination and CT.

[Therapeutic possibilities of shoulder arthroscopy at the orthopedic clinic of the Charité and the surgical clinic Berlin-Weissensee].

We report on arthroscopic procedures of 279 shoulder joints which were done in two hospitals of East-Berlin. We stress out the intention to arthroscopic diagnostic and simultaneous surgery. Arthroscopic surgery was mainly performed as resections and exstirpations. In cases of luxation and severe rotator cuff tears the open revision was necessary to perform.

[The value of arthroscopy for diagnosis of instability of the shoulder joint].

As a glenohumeral instability is defined each case of transient recurrent and permanent decentration of the joint. We propose to differentiate primary and secondary glenohumeral instabilities. Arthroscopical diagnostic is helpful to classify the luxation and subluxation and for verify transient instabilities. In cases clinically snapping phenomena were noticed, arthroscopic findings were documented. A relation between those phenomena and arthroscopic findings is discussed.
