Comparative StudyNon-cross-linked porcine acellular dermal matrices for abdominal wall reconstruction.
Non-cross-linked porcine acellular dermal matrices have been used clinically for abdominal wall repair; however, their biologic and mechanical properties and propensity to form visceral adhesions have not been studied. The authors hypothesized that their use would result in fewer, weaker visceral adhesions than polypropylene mesh when used to repair ventral hernias and form a strong interface with the surrounding musculofascia. ⋯ Porcine acellular dermal matrix becomes incorporated into the host tissue and causes fewer adhesions to repair sites than does polypropylene mesh, with similar implant-musculofascia interface strength. It also inhibits adhesions to adjacent dermal matrix in the combination repairs. It has distinct advantages over polypropylene mesh for complex abdominal wall repairs, particularly when material placement directly over bowel is unavoidable.

Fibula free flap reconstruction of the pelvis in children after limb-sparing internal hemipelvectomy for bone sarcoma.
Neoadjuvant chemotherapy has improved the treatment of bone sarcomas, making wide resection with limb salvage frequently possible. However, resection of iliac tumors without reconstruction causes pelvic instability and significant leg length discrepancy. Free vascularized bone autograft reconstruction represents a potentially optimal method for iliac reconstruction because of the faster healing time and rapid hypertrophy of the grafts. Furthermore, living incorporated autograft may be more durable in the setting of radiation therapy or chemotherapy. The purpose of this study was to characterize the successful reconstruction of the pelvis in children using a triangular double-barrel fibula free flap following limb-sparing internal hemipelvectomy for sarcoma. ⋯ An "A-frame" double-barrel fibula free flap can be used effectively for reconstruction of the type I internal hemipelvectomy defect. It permits a return to ambulation and minimizes leg length discrepancy and other complications, which may be critical in the immature pediatric skeleton.

Facial transplantation: an anatomic and surgical analysis of the periorbital functional unit.
Complete loss of eyelid pair is associated with chronic discomfort, corneal ulceration, and visual impairment. Contemporary reconstructive techniques rarely provide functionally acceptable results. Composite tissue allotransplantation may provide a viable alternative. This study reports on neurovascular anatomy and technical details of harvesting an isolated periorbital unit and discusses its functional potential. ⋯ Surgical harvest of a functional periorbital allotransplant is technically feasible. Revascularization of the isolated periorbital unit is influenced by variations in regional anatomy and cannot be guaranteed by a single vascular pedicle. The orbicularis oculi muscle and its innervation can be preserved, and recovery, albeit without the certainty of reflexive blinking, is expected.

Psychosocial predictors of an interest in cosmetic surgery among young Norwegian women: a population-based study.
The present study investigated psychosocial factors expected to predict an interest in cosmetic surgery. It was hypothesized that body dysmorphic disorder-like symptoms, personality, interpersonal attachment insecurity, low self-esteem, poor body image, dissatisfaction with sexual life, distorted eating behavior, emotional distress, low education, poor relationship with parents and friends, teasing history, social acceptance of cosmetic surgery, and low level of physical activity would relate to an interest in cosmetic surgery. ⋯ The study gives new insights into psychosocial factors predicting an interest in cosmetic surgery. In addition to previously known predictors, having been teased for appearance and having children were positive predictors, whereas education and quality of relationship with parents were negative predictors of an interest in cosmetic surgery. The results may contribute to a better understanding of the various factors that may motivate an individual to undergo cosmetic surgery.
