Tumor-induced osteomalacia is a rare and often misdiagnosed condition that presents with progressively worsening unexplained chronic pain and proximal muscle weakness. The osteomalacia leads to multiple stress fractures which do not heal properly, leading to progressive disability. It is caused by chronic hypophosphatemia due to inappropriate urinary phosphate wasting. This is due to a typically benign mesenchymal tumor that over-secretes a phospaturic hormone. Neurologists need to appreciate the relevance of chronic hypophosphatemia in people with chronic unexplained pain, as timely diagnosis and treatment of tumour-induced osteomalacia can be curative.

Background Accumulating evidence suggests that primary aldosteronism (PA) is associated with several features of the metabolic syndrome, in particular with obesity, type 2 diabetes mellitus, and dyslipidemia. Whether these manifestations are primarily linked to aldosterone-producing adenoma (APA) or bilateral idiopathic hyperaldosteronism (IHA) remains unclear. The aim of the present study was to investigate differences in metabolic parameters between APA and IHA patients and to assess the impact of treatment on these clinical characteristics. Methods We conducted a retrospective multicenter study including 3566 patients with APA or IHA of Caucasian and Asian origin. We compared the prevalence of metabolic disorders between APA and IHA patients at the time of diagnosis and 1-year post-intervention, with special references to sex differences. Furthermore, correlations between metabolic parameters and plasma aldosterone, renin, or plasma cortisol levels after 1 mg dexamethasone (DST) were performed. Results As expected, APA patients were characterized by higher plasma aldosterone and lower serum potassium levels. Only female IHA patients demonstrated significantly worse metabolic parameters than age-matched female APA patients, which were associated with lower cortisol levels upon DST. One-year post-intervention, female adrenalectomized patients showed deterioration of their lipid profile, when compared to patients treated with mineralocorticoid receptor antagonists. Plasma aldosterone levels negatively correlated with the BMI only in APA patients. Conclusions Metabolic alterations appear more prominent in women with IHA. Although IHA patients have worse metabolic profiles, a correlation with cortisol autonomy is documented only in APAs, suggesting an uncoupling of cortisol action from metabolic traits in IHA patients.

Abstract In an effort to enhance the trustworthiness of its clinical practice guidelines, the Endocrine Society has recently adopted new policies and more rigorous methodologies for its guideline program. In this Clinical Practice Guideline Communication, we describe these recent enhancements—many of which reflect greater adherence to the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) approach to guideline development—in addition to the rationale for such changes. Improvements to the Society’s guideline development practices include, but are not limited to, enhanced inclusion of nonendocrinologist experts, including patient representatives, on guideline development panels; implementation of a more rigorous conflict/duality of interest policy; a requirement that all formal recommendations must be demonstrably underpinned by systematic evidence review; the explicit use of GRADE Evidence-to-Decision frameworks; greater use and explanation of standardized guideline language; and a more intentional approach to guideline updating. Lastly, we describe some of the experiential differences our guideline readers are most likely to notice.

AbstractIntroductionAlthough letters of reference (LORs) are required for postgraduate year one (PGY1) residency applications and used to distinguish between candidates, an evaluation of residency program director (RPD) perceptions and values surrounding LORs has not been described.ObjectiveThe aim of the study was to describe PGY1 RPDs' processes, values, and perceptions surrounding LORs.MethodsThis was a cross‐sectional descriptive survey. After assessing content validity, the Education and Training Practice and Research Network (PRN) taskforce sent a 25‐item electronic survey to 1266 PGY1 RPDs. Survey questions captured program demographics, LOR requirements, processes for LOR review, and perceptions about the value of LORs. Two open‐ended questions solicited suggestions for LORs and the existing standardized form; responses were evaluated via thematic analysis.ResultsA total of 291 (24%) programs completed the survey. LORs were rated as extremely or quite valuable by 82% of respondents and moderately valuable by 16% of respondents. Scoring rubrics for LOR evaluation were used by 79% of programs, and performance ratings were reported to impact interview consideration by a majority of programs. Accuracy, detailed comments, and inclusion of specific candidate strengths and areas for improvement were rated as extremely or quite important characteristics by 90% or more of respondents. Specific strengths were reported to be present in LORs more than half of the time by 81% of programs; however, accuracy, detailed comments, and inclusion of specific areas for improvement were only reported to be present about half the time or less by 41%, 63%, and 63% of respondents. Among 207 suggestions submitted to improve LOR utility, common themes included a desire for LOR authors to have candid discussions with candidates prior to letter writing, to contextualize their relationship with the candidate, and provide honest and specific assessments.ConclusionLORs remain highly valued by PGY1 RPDs during application review. Several notable findings were observed, resulting in recommendations for LOR authors, residency applicants, and the standardized LOR form.

The use of social media continues to increase in health care and academia. Health care practice, particularly the oncologic field, is constantly changing because of new knowledge, evidence-based research, clinical trials, and government policies. Therefore, oncology trainees and professionals continue to strive to stay up-to-date with practice guidelines, research, and skills. Although social media as an educational and professional development tool is no longer completely new to medicine and has been embraced, it is still under-researched in terms of various outcomes. Social media plays several key roles in professional development and academic advancement. We reviewed the literature to evaluate how social media can be used for professional development and academic promotion of oncology professionals.

Two infants and one child died suddenly and unexpectedly while receiving central venous hyperalimentation. The catheter tip in each case was wedged against myocardium resulting in myocardial necrosis and pericardial effusion. The importance of avoiding intracardiac indwelling hyperalimentation catheters is stressed.

During the past two decades, anatomy instruction has changed due to curricular reforms in medical schools. Reduction in total hours of anatomy course and cadaver dissection, as well as shifts towards an integrated curricula has raised questions whether changes have had a negative impact on the students’ knowledge of anatomy. Our purpose was to investigate the effect of changes in course hours, curriculum type, and laboratory experience on USMLE Step 1 and Step 2 CK scores. Results of 2009 AAA online survey of anatomy course directors from 54 LCME‐accredited schools were matched with USMLE scores for 6,411 examinees taking Step 1 for the first time in 2009. The USMLE scores included Step 1 total test scores, Step 1 gross anatomy sub‐scores, and Step 2 CK total test scores. Analyses of data indicate that for all three USMLE scores, examinees from schools with stand‐alone gross anatomy courses slightly outperformed examinees from schools with integrated curricula. Conversely, the number of course hours had no effect on how students performed on Step 1 or Step 2 CK. Examinees that were exposed to both dissection and prosection slightly outperformed on Step 2 examinees that had dissection only. While these relationships are statistically significant, they may not be practically meaningful and more research is needed to fully explore different aspects of anatomy curricula and retention of anatomy knowledge.
