Case ReportsFree innervated latissimus dorsi muscle flap for reconstruction of full-thickness abdominal wall defects.
Full-thickness abdominal wall defects continue to be a challenge for the reconstructive surgeon. The most frequently used reconstructive techniques are transfer of a pedicled, local abdominal flap or a distant flap from the thigh region. The purpose of this paper is to present a new approach to full-thickness abdominal wall reconstruction using an innervated free latissimus dorsi musculocutaneous flap. ⋯ The combination of the dermal layer with an innervated free latissimus dorsi muscle provides a strong, vascularized fascial repair as well as an overlying vascularized soft-tissue coverage. In conclusion, adequate functional dynamic reconstruction of full-thickness abdominal wall defects is possible using an innervated free latissimus dorsi muscle flap. The reinnervated latissimus dorsi muscle is suitable for reconstitution of the missing functional and anatomic components of complex abdominal wall defects.

Regional blocking techniques as noted in dentistry, anesthesia, and anatomy texts may result in inconsistent and imperfect analgesia when needed for facial aesthetic surgery. The advent of laser facial surgery and more complicated aesthetic facial procedures has thus increased the demand for anesthesia support. ⋯ This sequence of bilateral blocks will routinely provide profound full facial anesthesia. Certain groupings of blocks are effective for perioral or periorbital laser surgery.

Comparative StudyA new evaluation system to predict the sequelae of late obstetric brachial plexus palsy.
Obstetric brachial plexus palsy has two distinct categories: (1) early obstetric brachial plexus palsy (or obstetric brachial plexus palsy in an infant) and (2) late obstetric brachial plexus palsy with deformity (or obstetric brachial plexus palsy in a child). Both early and late obstetric brachial plexus palsy lack a uniform evaluation system, and this makes correlation between them difficult. Clinical evaluation of obstetric brachial plexus palsy in infants is difficult, but in children it is easier. ⋯ The Klumpke score gives points for lower plexus functions including wrist extension, wrist flexion, metacarpophalangeal joint extension, interphalangeal joint extension, finger flexion, thumb adduction, and thumb abduction. The aims of this evaluation system are to determine the relationships between early and late obstetric brachial plexus palsy, to predict the progressive changes that take place with aging, and to propose the possible operation procedures to reconstruct. However, this evaluation system may differ by time and may not be suitable for comparisons between pre- and postreconstruction.

Randomized Controlled Trial Clinical TrialThe effects of hyaluronidase on the efficacy and on the pain of administration of 1% lidocaine.
Despite current clinical practice, there is no objective evidence to demonstrate the efficacy or pain on injection when hyaluronidase is added to lidocaine as an anesthetic combination for local anesthesia. To evaluate the usefulness of hyaluronidase added to lidocaine in affecting pain on injection and effectiveness of local anesthesia, a prospective, randomized, double blind study comparing 1% lidocaine preparations with and without hyaluronidase (15 U/cc) was conducted. A paired experiment was done with each subject receiving both treatments. ⋯ In addition, the hyaluronidase additive significantly decreases the amount of tissue distortion (p < 0.0001) without decreasing the efficacy of anesthetic action (p = 0.01). However, adding hyaluronidase to 1% lidocaine significantly increased the pain on injection (p = 0.0002). The injections of small amounts of hyaluronidase-containing solutions in this experiment did not produce any visible effects at 5 to 7 days after injection; however, the effect of hyaluronidase upon wound healing was not studied.
