Pectoralis Major Tendon Reconstruction With Achilles Tendon Allografts Utilizing Combined Pulvertaft Weave and Onlay Techniques.

Surgical treatment of chronic pectoralis major tears presents a technical challenge, as injury chronicity may preclude the ability to perform a direct repair. Many techniques have been described to repair an acute pectoralis tendon rupture, including utilization of unicortical buttons within the humeral footprint. In the chronic setting when direct repair is not possible, reconstruction with allograft tissue can restore strength, improve cosmesis, and yield high functional outcomes; however, literature is limited to small case series.

[Extended nasal skin reconstruction with a retroauricular free flap harvested on the superficial temporal pedicle].

The microsurgical coverage of large nasal skin avulsion was performed in a 40 years old patient after a human bite. Widely exposing the columelle, the alar cartilages and the distal part of the septum, the defect was covered with a retroauricular free flap harvested on the superficial temporal pedicle and transferred on the upper labial vessels in the nasogenian area. Thanks to its excellent colour and texture match with the nose integuments, this flap enjoyed of an optimal integration in the centrofacial area.

After portal branch ligation in rat, nuclear factor kappaB, interleukin-6, signal transducers and activators of transcription 3, c-fos, c-myc, and c-jun are similarly induced in the ligated and nonligated lobes.

Several studies have emphasized the involvement of transcription factors, cytokines, and proto-oncogenes in initiating the regenerative process after partial hepatectomy. To assess whether these events do specifically occur in a cellular system undergoing regeneration, we studied the induction of nuclear factor kappaB (NFkappaB), interleukin-6 (IL-6), signal transducers and activators of transcription 3 (Stat3), c-fos, c-myc, c-jun, after portal branch ligation (PBL), which produces atrophy of the deprived lobes (70% of the liver parenchyma), whereas the perfused lobes undergo compensatory regeneration. Nuclear extracts and total RNA were prepared from control livers as well as from atrophying and regenerating lobes at 0.
