    Description / Table of Contents: Abstract Traumatic instability of the shoulder has to be distinguished from instability due to capsular hyperlaxity if a stable shoulder and good functional results are to be achieved after surgery. Physical examination, radiological studies and arthroscopy are the most important diagnostic tools for this distinction. On the basis of our own experience and the results reported in the literature, we propose a strategy of patient selection for an arthroscopic stabilizing procedure. This procedure is indicated for first-time, traumatic dislocation and for chronic instability with a history of fewer than five recurrences without hyperlaxity.
    Notes: Zusammenfassung Die traumatische Schulterinstabilität muss von der Instabilität aufgrund hyperlaxer Kapsel-Band-Strukturen unterschieden werden, um dem therapeutischen Ziel einer stabilen und in ihrer Funktion nicht gestörten Schulter nahe zu kommen. Hierzu sind die klinische, radiologische und arthroskopische Diagnostik entscheidend. Auch der Enstehungsmechanismus und die Häufigkeit der Luxationen müssen berücksichtigt werden. Aufgrund der bisher gemachten Erfahrung und den in der Literatur verfügbaren Ergebnissen entstand eine Therapiestrategie der traumatischen Schulterinstabilität, die in Abhängigkeit von der präoperativen Reluxationsrate, den anatomischen Gegebenheiten und dem Anspruch des Patienten eine Selektion für oder wider eine arthroskopische Stabilisierungsoperation vorschlägt. Die Indikation zu diesem Eingriff sehen wir bei der traumatischen Erstluxation und der rezidivierenden traumatischen Schulterinstabilität ohne Hyperlaxität, wenn weniger als 5 Rezidive in der Anamnese zu erheben sind.

    Notes: Abstract The aim of the present study was to investigate the occurrence and autoregulation of both glucocorticoid receptor mRNAs in rat gastrocnemius muscle. The expression of both receptor forms was studied 1, 4 or 12hours after intra-tracheal instillation of a high dose (100μg) of budesonide; muscular expression was compared with glucocorticoid receptor expression in lung tissue. After Northern blot analysis, hybridization was performed with glucocorticoid receptor, glyceraldehyde-3-phosphate dehydrogenase and glutamine synthetase probes. In the gastrocnemius muscle, both the α and β glucocorticoid receptor mRNA forms were detected and found to be downregulated four hours after the budesonide instillation. α/β glucocorticoid receptor ratios were lower in the gastrocnemius (1.1±0.2) than in the lungs (2.6±0.6). In the lungs, at all time points, the average α glucocorticoid receptor mRNA levels did not differ from controls, although glutamine synthetase mRNA levels were upregulated. The β glucocorticoid receptor mRNA was slightly reduced at 1 and 4hours. In conclusion, after intra-tracheal instillation of budesonide, both α and β glucocorticoid receptor forms were downregulated in muscle tissue. The difference in α/β glucocorticoid receptor mRNA ratios and concentrations between lung and gastrocnemius muscle supports the hypothesis of differential gene regulation by glucocorticoids in different cell types. © Kluwer Academic Publishers.
