The Urogenital Epithelium and Corporal Tissues Are the Primary Targets of Rejection in Penile Vascularized Composite Allotransplantation: A New Real-Time Tissue-Based Monitoring System.
Although significant surgical advances have been made in the form of microvascular surgery and autologous free tissue transfer, penile reconstruction still poses several difficult challenges. Although interest in penile vascularized composite allotransplantation has grown since the first attempted transplant in 2006, little is known regarding the kinetics of rejection and subsequent function of penile allografts. The penis contains multiple tissue types that are not qualified by the Banff 2007 vascularized composite allotransplantation classification system, including urogenital mucosal epithelium and erectile tissues. In this study, the authors investigate the propagation of rejection and the resultant function following rejection in rat and human penile tissues. ⋯ These findings are the first to describe the kinetics of rejection in both human and rat penile vascularized composite allotransplantation and that the urethral mucosa is the most antigenic, suffering the highest level of rejection-associated apoptosis and peripheral blood mononuclear cell proliferative aggregation.

Comparative StudyArterial Wall Penetration Forces in Needles versus Cannulas.
If safety is defined as the diminished ability to penetrate facial arteries, the goal of this study was to investigate whether different-sized cannulas are safer than correspondingly sized needles for the application of facial soft-tissue fillers. ⋯ Therapeutic, V.

Role of Early Application of Pressure Garments following Burn Injury and Autografting.
Pressure garment therapy, used for reduction of postburn scarring, is commonly initiated after complete healing of the wound or autograft. Although some clinicians have suggested that earlier treatment may improve outcomes, the effect of early initiation of therapy has not been studied in a controlled environment. ⋯ Early application of pressure garments is safe and effective for reducing scar thickness and contraction and improving biomechanics. This preclinical study suggests that garments should be applied as soon as possible after grafting to achieve greatest benefit, although clinical studies are needed to validate the findings in humans.

Meta AnalysisPatient-Reported Outcome Measures for Soft-Tissue Facial Reconstruction: A Systematic Review and Evaluation of the Quality of Their Measurement Properties.
A patient's health-related quality of life can be significantly impacted by facial scarring and disfigurement. Facial soft-tissue reconstruction should aim to improve this, with outcomes measured from the patient's perspective using patient-reported outcome measures. This systematic review identifies patient-reported outcome measures for soft-tissue facial reconstruction and appraises their methodologic and psychometric properties using up-to-date methods. ⋯ This is the first systematic review to identify and critically appraise patient-reported outcome measures for soft-tissue facial reconstruction using internationally accepted criteria. Four questionnaires were deemed to have adequate levels of methodologic and psychometric evidence, although further studies should be conducted before they are used routinely in patients undergoing facial reconstruction. Through the use of psychometrically well-validated questionnaires, it is hoped that patients' concerns can be truly appreciated, the level of care improved, and the quality of reconstructive options offered advanced.

Approximately 25 percent of major limb amputees will develop chronic localized symptomatic neuromas and phantom limb pain in the residual limb. A method to treat and possibly prevent these pain symptoms is targeted reinnervation. Previous studies prove that targeted reinnervation successfully treats and, in some cases, resolves peripheral neuropathy and phantom limb pain in patients who have undergone previous amputation (i.e., secondary targeted reinnervation). ⋯ Dumanian et al. first noted the improvement of symptomatic neuroma and phantom limb pain in patients undergoing targeted reinnervation to provide intuitive control of upper limb prostheses. These findings have been substantiated by multiple previous studies at various amputation levels. This study extends the success of targeted muscle reinnervation to below-knee amputations and provides a description for this technique.
