Integrating complementary and alternative medicine instruction into health professions education: organizational and instructional strategies.

A few years ago, the National Institutes of Health National Center for Complementary and Alternative Medicine funded a program called the Complementary and Alternative Medicine (CAM) Education Project. Grantees were 14 medical and nursing schools and the American Medical Student Association, which funded six additional medical schools. Grants were awarded in cohorts of five per year in 2000, 2001, and 2002-2003.The R25 grant recipients identified several major themes as crucial to the success of integrating CAM into health professions curricula. The rationale for integrating CAM curricula was in part to enable future health professionals to provide informed advice as patients dramatically increase the use of CAM. Success of new CAM education programs relied on leadership, including top-down support from institutions' highest administrators. Formal and informal engagement of key faculty and opinion leaders raised awareness, interest, and participation in programs. A range of faculty development efforts increased CAM-teaching capacity. The most effective strategies for integration addressed a key curriculum need and used some form of evidence-based practice framework. Most programs used a combination of instructional delivery strategies, including experiential components and online resources, to address the needs of learners while promoting a high level of ongoing interest in CAM topics. Institutions noted several benefits, including increased faculty development activities, the creation of new programs, and increased cross- and inter-university collaborations. Common challenges included the need for qualified faculty, crowded and changing curricula, a lack of defined best practices in CAM, and post-grant sustainability of programs.     

MRI of the Stener lesion

Objective. To assess the utility of MR in detecting surgically induced Stener lesions (displaced thumb ulnar collateral ligaments) in cadaveric models. Design. Six cadaver thumbs had ulnar collateral ligament (UCL) tears created surgically. MR examinations (2D STIR and 3D GRASS) were performed identically on all specimens both before displacement (non-Stener) and after displacement (Stener lesion) of the UCL. The MR images were then randomly numbered. Each image was evaluated separately in blinded fashion by four musculoskeletal radiologists for the presence or absence of a Stener lesion. Each radiologist reinterpreted the images after an interval of several days. The interpretation was based on previously published criteria for Stener lesion diagnosis by MR. Results. The sensitivity of GRASS ranged from 0.17 to 0.67 with the most experienced reader scoring the lowest. The specificity of GRASS ranged from 0.33 to 1.0 (most experienced reader 0.67, 0.83). STIR had a sensitivity of 0.00–0.17 and a specificity of 0.53–0.83. The values for inter- and intraobserver agreement were measured. The intraobserver for GRASS was 0.27–0.75 (most experienced reader 0.75). Conclusions. 2D imaging is probably inadequate for the evaluation of Stener lesions. The most likely reason is that the STIR slice thickness of 3 mm limits resolution of small UCLs. The poor sensitivity and specificity of GRASS as well as poor interobserver agreement suggest that MR may not be sufficiently accurate for Stener lesion evaluation.     

Computerized bone densitometric analysis: operator-dependent errors

PURPOSE: To determine the nature and relative frequency of operator-dependent data analysis errors in dual x-ray absorptiometry. MATERIALS AND METHODS: Over 40 months, 2,528 dual x-ray absorptiometric examinations of the forearm, femoral neck, and lumbar spine were performed by 11 technologists by using standard techniques and software. Each analysis was reviewed by a radiologist; errors were recorded and corrected. RESULTS: There were no forearm analysis errors. There were 24 (0.9%) femoral neck analysis errors, of which 23 resulted from misplacement of the analysis region. There were 33 (1.3%) spinal analysis errors, of which 24 resulted from misplacement of intervertebral disk space markers. Analysis errors of the femur and spine resulted in six misdiagnoses (0.2%). CONCLUSION: Misdiagnosis due to analysis errors is rare. Femoral neck analysis errors were easily detectable, but accurate spinal analyses depended on accurate identification of vertebral end plates and posterior elements. Nonetheless, these potentially serious errors can be detected and corrected if the analyses are reviewed and interpreted by a supervising physician who is familiar with the relevant anatomy, proper analysis techniques, and factors--such as artifacts--that adversely affect the accuracy of the analysis.     

Successful reconstruction of natural femoral anteversion using a short femoral stem in total hip arthroplasty surgery

ObjectiveTotal hip arthroplasty (THA) involves postoperative risks, such as thigh pain, periprosthetic fractures, and stress yielding. Short, anatomical, metaphyseal-fitting, cementless femoral stems were developed to reduce these postoperative risks. This study aimed to examine the “MiniMAX” prosthesis, which is a new generation, short, anatomical femoral stem made by Medacta.MethodsPatients underwent a low-dose computed tomography scan. Femoral anteversion was measured. We assessed the position and anteversion of the femoral component and compared them with the unoperated side. We also assessed the patients’ satisfaction and functional levels at 6 months postsurgery using the Harris Hip Score (HHS) and the Oxford Hip Score (OHS).ResultsNineteen individuals were recruited in this study. We found no significant difference in femoral anteversion between the operated hip and the native hip. Using the HHS and OHS questionnaires, we found clinical improvement in the 6-month postoperative scores compared with the preoperative scores.DiscussionThe new-generation, short, anatomical femoral stem made by Medacta is successful in reproducing natural femoral anteversion, while also improving patients’ functioning and lifestyle. Future large-scale, prospective comparison trials are required to further investigate this topic.     

Strategies to promote resilience,empathy and well-being in the health professions: Insights from the 2015 CENTILE Conference

The high prevalence of physician burnout is of great concern and may begin with observed declines in empathy and increases in stress and burnout in medical and health professions students. While underlying causes have been described, there is less certainty on how to create effective interventions in curricula and workplace. In October 2015, The Center for Innovation and Leadership in Education (CENTILE) at Georgetown University, together with MedStar Health, Georgetown’s clinical partner, and six academic institutions sponsored a conference in Washington, DC. The goal was to discuss the current state of stress and burnout in the health professions, and to share best practices on strategies to promote resilience, empathy and well-being in students, residents, faculty and practitioners across health professions. In this issue of Medical Teacher, three articles address pertinent themes of the conference. Maslach and Leiter provide insights into burnout and strategies to alleviate it. Ekman and Krasner discuss various types of empathy and how neuroscience can be used to effectively cultivate empathy. In the third paper, Kreitzer and Klatt highlight three successful curricular interventions that foster self-awareness and boost resilience. Ultimately, effective strategies will be needed to address this issue at both the individual and organizational levels.     

Restoration of a phosphaturic response to parathyroid hormone in the immature rat

Recent studies have shown that immature rats display a diminished sensitivity to the phosphaturic effects of parathyroid hormone (PTH), and that the responsiveness to PTH increases with age. The attenuated phosphaturia may reflect an inability of the neonate to respond to the hormone because of functional immaturity of the developing kidney. Alternatively, PTH may actually inhibit tubular phosphate reabsorption in the neonate but, due to other phosphate conservation mechanisms, no phosphaturia occurs. Our objective was to determine whether a phosphaturic response to PTH would be elicited in immature rats during infusion of moderate amounts of phosphate (Pi). Clearance experiments were performed on 26 acutely thyroparathyroidectomized immature Wistar rats (3-5 wk of age) fed a normal Pi diet (0.63%). In response to infusion of either Pi (1 mumol/min.100 g) (group I) or PTH (8.3 ng/min.100 g) (group II) alone, the fractional excretion of phosphate rose minimally (from 0.01 +/- 0.01% to 4.9 +/- 1.9% and from 0.12 +/- 0.12% to 2.9 +/- 1.4% for groups I and II, respectively). However, when Pi and PTH were combined either Pi first followed by PTH (group III) or PTH first followed by Pi (group IV), the fractional excretion of Pi rose dramatically (from 0.01 +/- 0.01 to 21.8 +/- 3.5% and from 0.04 +/- 0.04 to 27.7 +/- 3.3% for groups III and IV, respectively). A significant increase in urinary cAMP excretion occurred during infusion of PTH even when Pi excretion was minimal, but there was no further increase in urinary cAMP during the combined infusion of Pi and PTH.(ABSTRACT TRUNCATED AT 250 WORDS)     

PACS and RIS: approaches to integration

PACS and RIS have traditionally been discrete information systems with separate databases. Maintaining more than one database containing identical data sets creates the potential for outdated information being used in parallel with accurate information. Today, because of increased implementation of PACS and improved Web technology, this problem must be solved. Furthermore, as PACS technology is applied to areas outside radiology such database issues become more critical. Application of XML offers a cost-effective and workable solution to many of the thorniest problems that will likely become more prevalent in the post-Y2K era.
