Reconstruction of extensive lower limb defects with thoracodorsal axis chimeric flaps.
Extensive defects of the lower extremities are usually reconstructed with microvascular free flaps because of inadequate local tissues and wound complexity. Many attempts have been made to reconstruct such defects using the chimeric flap concept, enabling flaps with larger surface areas to be used while maintaining economical tissue use. The latissimus dorsi chimeric flap is one of the most useful tools for resurfacing extensive limb defects. ⋯ Therapeutic, IV.

Randomized Controlled Trial Comparative StudyAnalgesic efficacy of lidocaine for suction-assisted lipectomy with tumescent technique under general anesthesia: a randomized, double-masked, controlled trial.
Suction-assisted lipectomy is one of the most common procedures performed in plastic surgery. To minimize blood loss and to obtain adequate analgesia, a liquid solution is infiltrated into the subcutaneous plane before suction. The objective of this study was to determine whether the use of lidocaine in the infiltration solution reduces postoperative pain. ⋯ Therapeutic, I.

Comparative StudyMicrovascular autologous breast reconstruction in the context of radiation therapy: comparing two reconstructive algorithms.
When postmastectomy radiation therapy is anticipated, delaying autologous reconstruction prevents radiation delivery issues and radiation-induced contour irregularities. Delayed-immediate autologous breast reconstruction may allow for maintenance of the breast skin envelope as compared with delayed reconstruction with the temporary insertion of a tissue expander. The authors compared perioperative complications and revision surgery rates of comparative cohorts to determine which method is preferable. ⋯ Therapeutic, III.

Comparative StudyBiological and electrophysiologic effects of poly(3,4-ethylenedioxythiophene) on regenerating peripheral nerve fibers.
Uninjured peripheral nerves in upper-limb amputees represent attractive sites for connectivity with neuroprostheses because their predictable internal topography allows for precise sorting of motor and sensory signals. The inclusion of poly(3,4-ethylenedioxythiophene) reduces impedance and improves charge transfer at the biotic-abiotic interface. This study evaluates the in vivo performance of poly(3,4-ethylenedioxythiophene)-coated interpositional decellularized nerve grafts across a critical nerve conduction gap, and examines the long-term effects of two different poly(3,4-ethylenedioxythiophene) formulations on regenerating peripheral nerve fibers. ⋯ Both poly(3,4-ethylenedioxythiophene) formulations were compatible with peripheral nerve regeneration at 3 months. This study supports poly(3,4-ethylenedioxythiophene) as a promising adjunct for peripheral nerve interfaces for prosthetic control and other biomedical applications because of its recognized ionic-to-electronic coupling potential.
