    Description / Table of Contents: Summary This review describes structure, function and healing of tendinous tissue and discusses new biologically based treatment options to modulate tendon healing. The repair process after tendon rupture results in a morphologically different and biomechanically inferior structure compared to a normal tendon. The collagen fibril diameters are decreased months after the traumatic lesion and show also different phenotypes. We know that cytokines and growth factors are key components for normal tissue development and regulate wound healing processes. Some growth factors have been detected to influence tenocytes by promoting cell proliferation and matrix synthesis. Application of the adequate growth factors at certain periods during the repair process might improve the healing result after tendon rupture. However, most of these growth factors are proteins which are rapidly metabolized by the organism. Transfer of growth factor genes into tenocytes might eliminate this problem by a continuous local release of growth factors at the healing site.
    Notes: Zusammenfassung Der Artikel beschreibt überblicksartig Struktur und Funktion von Sehnengewebe sowie die Abläufe im Rahmen der Sehnendefektheilung und mögliche therapeutische Einflussnahme. Im Vergleich zum unverletzten Sehnengewebe heilen Sehnenläsionen mit einem morphologisch unterschiedlichen und biomechanisch inferioren Regenerat. Vor allem die für die Funktion der Sehne entscheidenden kollagenen Fasern weisen langfristig veränderte Phänotypen und reduzierte Fibrillendurchmesser auf. Eine Einflußnahme auf die Prozesse im Rahmen der Sehnenheilung sind mittels zellulärer Wachstumsfaktoren denkbar. Zelluläre Wachstumsfaktoren nehmen während der embryonalen Gewebedifferenzierung und im Rahmen von Wundheilungsprozessen eine entscheidende Schlüsselfunktion ein. Von Wachstumsfaktoren ist bekannt, dass sie die Zellproliferation und Chemotaxis stimulieren, die Angiogenese vermitteln und die Zelldifferenzierung beeinflussen. Darüber hinaus regulieren sie zelluläre Synthese- und Sekretionsaktivität von Matrixbestandteilen. Der therapeutische Einsatz von heilungsstimulierenden Wachstumsfaktoren, bzw. der Transfer entsprechender Gene, könnte hierbei ein erfolgsversprechender Ansatz hinsichtlich einer Verbesserung der Sehnenheilung sein.

    Notes: Abstract The aim of the present analyses was to evaluate differences in suicidality (past suicide attempts, suicidal thoughts at time of admission and completed suicides during the hospital stay) between bipolar and unipolar depressed inpatients. Apart from a higher frequency of past suicide attempts in bipolar depressed patients (26.6% in bipolar vs. 17.8% in unipolar patients), findings do not indicate any further differences in suicidality (suicidal thoughts (about 40% in both groups) and completed suicides during the hospital stay (0.8% in both groups)) between bipolar and unipolar patients. Factors with a predictive value for suicidal thoughts at the time of admission were a positive family history for affective disorders, past suicide attempts, and the depressive and paranoid hallucinatory syndrome (all associated with an increased risk). Female gender, an older age at hospitalisation and a longer duration of the illness were found to be associated with a lower probability for having suicidal tendencies at the time of admission. The risk for committing suicide during the hospital stay was increased if the patients had a history of past suicide attempts and suicidal thoughts at the time of admission. A more pronounced depressive syndrome at time of admission was slightly associated with a lower risk of committing suicide.

    Notes: Abstract This paper gives a critical review of recommendations concerning the drug treatment of acute bipolar depression. The suggestions of different guidelines and consensus papers, especially in US-American and Canadian psychiatry, have a strong tendency against antidepressants in bipolar depression; they prefer mono-therapy with mood stabilizers and, in the case of co-medication with mood stabilizers and antidepressants in severe depression, to withdraw the antidepressant as early as possible. The intention of this restrictive use is to avoid the risk of mania and the risk of rapid cycling induced by antidepressants. However, apparently the risk of suicidal acts, which is as prominent in bipolar depression as in unipolar depression, has been totally neglected. Furthermore, the fact that none of the mood stabilizers have proven their antidepressive efficacy leads not only to the risk of depression-related suicidal behavior but also to the risk of chronicity of depressive symptoms due to undertreatment. Altogether the view expressed in some guidelines and consensus papers appears not well balanced. Furthermore, the fact that apparently the selective serotonin re-uptake inhibitors and possibly some other modern antidepressants have only a low risk of inducing a switch to mania should stimulate a rewriting of the guidelines on drug treatment in acute bipolar depression in a less restrictive way concerning the use of antidepressants.
