Approved and investigational fluorescent optical imaging agents for disease detection in surgery.

Fluorescent optical imaging is becoming an increasingly attractive imaging tool that physicians can utilise as it can detect previously 'unseen' changes in tissue at a cellular level that are consistent with disease. This is possible using a range of fluorescently labelled imaging agents that, once excited by specific wavelengths of light, can illuminate damaged and diseased tissues. For surgeons, such agents can permit dynamic, intraoperative imaging providing a real-time guide as they resect diseased tissue.

"The journey of a thousand miles begins with one step": An Asian American perspective on mentoring in neuropsychology.

OBJECTIVE: The Asian Neuropsychological Association (ANA) is a recently established cultural identity-based organization with the mission to ensure accessibility and provision of culturally sensitive neuropsychological services for individuals of Asian descent. One of ANA's programmatic goals has been to foster a pipeline of neuropsychologists through mentoring and networking. In this paper, we aim to understand the historical context as well as unique considerations that are relevant for mentoring in the Asian American community. METHODS: A search of the existing literature in psychology and allied fields such as counseling and sociology was conducted to identify and formulate suggestions for mentoring culturally diverse communities, with a specific focus on Asian Americans. Firsthand narrative descriptions of effective examples of mentoring experiences in the context of shared values are discussed. FINDINGS AND IMPLICATIONS: This paper reviews the historical context and establishes an initial contextual foundation for increasing knowledge about best practices that can be used to establish effective mentoring relationships for Asian Americans. Six key considerations were identified: model minority myth, acculturation and enculturation, ethno-racial status and gender, the context of communication, quantity and quality of mentorship, and unique values specific to the Asian American community. Our findings identify the value of cultural identity-based organizations in creating communities that can support the professional development of future neuropsychologists at various career stages. Overall, findings have implications for maintaining the relevance of the field of neuropsychology in adequately serving an increasingly culturally diverse national and international population.

Intrmedullary versus extramedullary fixation of lateral malleolus fractures.

INTRODUCTION: Intramedullary nails (IM nails) now include dedicated fibular nails for lateral malleolus fractures. This study reviewed nail versus plate for fixation of unstable ankle fractures. DESIGN: Systematic review and meta-analysis of published reports. RESULTS: Four studies met the inclusion criteria, including 375 patients. Two included studies were randomised-control studies and two were non-randomised case series. The implants investigated included: Knowles Pins, Fibular Nails, Rush Rods and Inyo Nails. The overall risk of bias was high. Pooled data showed a statistically significant lower risk of wound infection (RR 0.10; 95% CI 0.02 to 0.44), symptomatic hardware (RR 0.14; 95% CI 0.05 to 0.35) and removal of hardware (RR 0.57; 95% CI 0.39 to 0.81) with intramedullary nail fixation. CONCLUSIONS: There is a paucity of literature upon which to draw reliable conclusions. There was a high risk of bias towards favourable outcomes for the nail group. It would appear that intramedullary nail fixation of distal fibular fractures can outperform conventional fixation with plate and screws. There is a need for adequately powered, scientific trials.
