The objectives of this paper are to help specialists in Physical and Rehabilitation Medicine plan their careers, influence the future of the PRM specialty and advocate effectively for those with limitations of functioning. The experiences of the authors are the sources of its observations and suggestions. The senior author has had extensive national and international experience in the specialty as a clinician, teacher, researcher, manager, leader and advocate. The junior author adds the insights of one who only recently has become immersed in PRM. The following are suggestions and observations the authors believe could contribute to the future success of individual PRM specialists and the PRM specialty. ①Review and reinforce the significant accomplishments of PRM over the last 70 years. It has significantly expanded the focus of health care to include the importance of functioning. ②Identify the specialty′s current strengths, weaknesses, threats and opportunities. As a clinical specialty, it has expanded nationally and internationally, yet its research contributions remain limited. The absence of an evidence base for much of its activity risks reduced support from payers, yet the population needing its services continues to expand. ③Develop strategies to increase the ability of PRM specialists and PRM to improve the lives of people with or likely to have limitations of functioning. These strategies could include sharing best practices, supporting effectiveness research and developing expert consensus guidelines. The need for physicians who are experts in the strategies of improving the lives of those with complex problems of functioning will continue to expand. This need will assure the continuation of the specialty of PRM as long as it improves the abilities of its members to help those with problems of functioning, and it advocates for those whom its members serve.

Early detection of environmental disruption, unintentional or otherwise, is increasingly desired to ensure hazard minimization in many settings. Here, using a field-portable, smartphone fluorimeter to assess water quality based on the pH response of a designer probe, a map of pH of public tap water sites has been obtained. A custom designed Android application digitally processed and mapped the results utilizing the global positioning system （GPS） service of the smartphone. The map generated indicates no disruption in pH for all sites measured, and all the data are assessed to fall inside the upper limit of local government regulations, consistent with authority reported measurements. This implementation demonstrates a new security concept： network environmental forensics utilizing the potential of novel smartgrid analysis with wireless sensors for the detection of potential disruption to water quality at any point in the city. This concept is applicable across all smartgrid strategies within the next generation of the Internet of Things and can be extended on national and global scales to address a range of target analytes, both chemical and biological.

Practical Handbook of Echocardiography: 101 Case Studies Echocardiography is now one of the most commonly used diagnostic imaging tools, yet many clinicians remain unaware of the range of conditions echo can reveal or how echo can be used to help plan therapy. Moreover, it can be quite challenging even for the most seasoned practitioners to spot unusual conditions. Compiled by three echocardiographers with more than 100 years of clinical experience between them, Practical Handbook of Echocardiography uses a case-based approach to explain in detail the full spectrum of echocardiographic modalities and how to optimize their use in the clinical setting. This practical new book: Covers the full gamut of echocardiographic modalities, including M-mode, 2-D,3-D and Doppler (PW, CW, color flow, tissue and strain), transesophageal (intra-operative and routine) and contrast Describes cases in both clinical and echocardiographic terms including very interesting cases and the new clinical techniques Features beautifully reproduced, well-labeled, full color echocardiograms Includes accompanying DVD with real-time video clips Appropriate for physician echocardiographers and all cardiologists, as well as echocardiographic technicians, Practical Handbook of Echocardiography is the ideal concise guide to using echocardiography to make definitive diagnoses and improve patient outcomes.
