Autologous nerve grafts are the current criterion standard for repair of peripheral nerve injuries when the transected nerve ends are not amenable to primary end-to-end tensionless neurorrhaphy. However, donor-site morbidities such as neuroma formation and permanent loss of function have led to tremendous interest in developing an alternative to this technique. Artificial nerve conduits have therefore emerged as an alternative to autologous nerve grafting for the repair of short peripheral nerve defects of less than 30 mm; however, they do not yet surpass autologous nerve grafts clinically. A thorough understanding of the complex biological reactions that take place during peripheral nerve regeneration will allow researchers to develop a nerve conduit with physical and biological properties similar to those of an autologous nerve graft that supports regeneration over long nerve gaps and in large-diameter nerves. In this article, the authors assess the currently available nerve conduits, summarize research in the field of developing these conduits, and establish areas within this field in which further research would prove most beneficial.

Melanoma is a common malignancy with a high survival rate amongst those diagnosed early. The management of advanced disease is challenging, and current chemosurgery techniques have minimal effect on survival. Nanotechnology, offers great potential in revolutionizing the management of melanoma. New molecules and nanoparticles are designed worldwide in an aim to improve the diagnosis and spread to sentinel lymph nodes and other organs. Novel drug delivery systems are formulated to optimise the distribution and pharmacokinetics of chemotherapeutic agents while reducing their toxic effects. The scope of such molecules extends to therapeutic applications including photodynamic and photothermic therapy where light is converted to heat to combat neoplastic lesions; immunotherapy where nanoparticles are used as immunomodulators or vaccines against cancer cells; and gene therapy which targets pro-oncogenes on signal transduction pathways. This review paper presents current knowledge of the use of nanotechnology in the management of cancer, with a focus on melanoma.

Background: Electively-managed conditions account for over 100 000 inpatient surgeries a year in the English National Health Service alone, with further procedures in other regions of the UK, or performed on an outpatient basis. To quality assure this care and to conduct research, effective outcome measurement is critical. Traditional surgeon-centric outcome measures correlate poorly with hand function and are seldom important to patients. There has been an advent in the use of patient reported outcome measures (PROMs) in hand surgery although consensus of PROM choice appears to be lacking. This systematic review aimed to describe the use of relevant PROMs in clinical research of electively-managed hand conditions. Methods: A PRISMA-compliant methodology was used. A bespoke search strategy was developed in conjunction with a search strategist, and applied to Medline, EMBASE, CINAHL and PSYCHINFO from 1992 to June 2017. Pre-specified stepwise inclusion criteria were used to identify studies describing adult patients undergoing treatment for electively-managed hand conditions distal to the distal radius, with clinical outcomes measured using one or more PROMs. Results: Of 4554 results, 834 met inclusion criteria. PROMs identified included 9 disease-specific, 8 site-specific and 4 generic quality of life measures. Across all, the Disabilities of the Arm, Shoulder and Hand (DASH) was the most commonly used (overall frequency 41.0%). The most commonly reported disease-specific measure was the Boston Carpal Tunnel Questionnaire (overall frequency 23.0%). The most commonly reported generic quality of life of measure was the SF-36 (overall frequency 4%). Time-analysis demonstrated predominance of site-specific PROMs since the year 2000. Conclusions: Various PROMs have been used to study electively-managed hand conditions, with site-specific PROMs most popular. However, there appears to be limited consensus on choices. A future systematic evaluation of the published psychometric properties of identified PROMs may inform standardisation of measurement.
