The effect of intracavernosal growth differentiation factor-5 therapy in a rat model of cavernosal nerve injury.
2006
OBJECTIVE To determine whether the intracavernosal application of growth differentiation factor-5 (GDF-5) influences nerve regeneration and erectile function after cavernosal nerve injury in a rat model. MATERIALS AND METHODS Thirty-two male Sprague-Dawley rats were randomly divided into four equal groups: eight had a sham operation (uninjured controls), while 24 had bilateral cavernosal nerve crush. The crush-injury groups were treated at the time of injury with an impregnated collagen sponge implanted into the right corpus cavernosum. The sponge contained no GDF-5 (injured controls), 2 µg (low concentration), or 20 µg GDF-5 (high concentration). Erectile function was assessed by cavernosa…
Letter: Tissue-Glue-Coated Collagen Sponge (TachoSil) for Minor Cerebral Dural Venous Sinus Laceration: What is the Evidence?
2015
We read with great interest the article by Gazzeri et al1 focusing on tissue-glue–coated collagen sponge (TachoSil) application to repair minor cerebral dural sinus lacerations. In their series, 57 consecutive patients were prospectively enrolled, and tears of the cerebral venous sinus were treated by TachoSil application directly to the site of the bleeding. In all patients, venous bleeding was managed initially by standard techniques for hemostasis such as compression, application of oxidized cellulose, or gelatin sponge. TachoSil application was used when standard measures failed to be effective, were excessively time- consuming or inadequate, or were considered risky. No complications r…
