RESUMEN

As medical ethics and professionalism education continues to equip medical students and residents with long-lasting tools, educators should continue to supplement proven teaching strategies with engaging, relatable, and generationally appropriate didactic supplements. However, popular teaching aids have recently been criticized in the literature and summative information on alternatives is absent. The purpose of this review is to evaluate and assess the functional use and application of short form audiovisual didactic supplements or "icebreakers" in medical ethics and professionalism teaching. A systematic review of both the medical and humanities literature (i.e., PubMed/MEDLINE, Cochrane Library, and JSTOR) was conducted from inception to August 1, 2019. Final articles were subjected to a qualitative appraisal and thematic analysis. Thirteen articles were included for final analysis. Sixty-nine percent (n = 9) of the studies were published after 2000. Two studies were qualitative, one study was quantitative, and the remaining articles were commentaries. Short form audiovisual media was most popular outside of the United States (n = 10). Sixty-nine percent (n = 9) of articles advocated for self-contained media in the form of trigger films or short films/videos, while the remaining articles (n = 4) discussed the use of TV/film clips. Producibility of media was exclusive to short/trigger films. Nine themes were identified in the content analysis: adaptability, conversation catalyst, effective, engaging, nuance, practice, producibility, real, and subject diversity. The three most common themes in descending order of frequency were: conversation catalyst, realness, and adaptability. Trigger films represent an effective and unique pedagogical strategy in supplementing current medical ethics and professionalism teaching at the medical school level.

RESUMEN

OBJECTIVE: To systematically evaluate the scientific literature examining the effect of corticosteroid type, dose, and volume of small- and intermediate-size joint injections on pain and function. TYPE: Narrative review. LITERATURE SURVEY: Medline (PubMed), Cochrane Central Register of Controlled Trial, and SportDiscus databases were searched. METHODOLOGY: Inclusion criteria included prospective studies evaluating pain- and/or function-related improvements following a corticosteroid injection of a small- or intermediate-size joint. SYNTHESIS: A total of 28 articles were included, all studying patients with osteoarthritis and/or rheumatoid arthritis. Eleven studies were randomized-controlled trials comparing corticosteroid injections to a control treatment and three were randomized trials comparing corticosteroid dose or type; the rest were prospective case series without a control. Most studies used 10 to 20 mg of methylprednisolone or triamcinolone for small joints and 20 to 40 mg for intermediate joints; wrist joints were the only joint studied that directly compared doses-20 mg was noninferior to 40 mg. Triamcinolone hexacetonide was found to be superior to methylprednisolone in the interphalangeal finger joints in a single randomized-controlled trial; no other studies compared steroid types in any joint. No studies evaluated the effect of volume on clinical outcomes. CONCLUSIONS: Very few studies directly examine the effect of corticosteroid type, corticosteroid dose, or injectate volume on clinical outcomes for small- or intermediate-size joint arthralgia. Future studies are needed to better elucidate the most effective treatment protocols. LEVEL OF EVIDENCE: IV.

RESUMEN

BACKGROUND AND OBJECTIVES: No previous study has assessed the outcomes of cooled radiofrequency ablation (C-RFA) of the medial branch nerves (MBN) for the treatment of lumbar facet joint pain nor compared its effectiveness with traditional RFA (T-RFA). This study evaluated 6-month outcomes for pain, function, psychometrics, and medication usage in patients who underwent MBN C-RFA versus T-RFA for lumbar Z-joint pain. METHODS: In this blinded, prospective trial, patients with positive diagnostic MBN blocks (>75% relief) were randomized to MBN C-RFA or T-RFA. The primary outcome was the proportion of 'responders' (≥50% Numeric Rating Scale (NRS) reduction) at 6 months. Secondary outcomes included NRS, Oswestry Disability Index (ODI), and Patient Global Impression of Change. RESULTS: Forty-three participants were randomized to MBN C-RFA (n=21) or T-RFA (n=22). There were no significant differences in demographic variables (p>0.05). A ≥50% NRS reduction was observed in 52% (95% CI 31% to 74%) and 44% (95% CI 22% to 69%) of participants in the C-RFA and T-RFA groups, respectively (p=0.75). A ≥15-point or ≥30% reduction in ODI score was observed in 62% (95% CI 38% to 82%) and 44% (95% CI 22% to 69%) of participants in the C-RFA and T-RFA groups, respectively (p=0.21). CONCLUSIONS: When using a single diagnostic block paradigm with a threshold of >75% pain reduction, both treatment with both C-RFA and T-RFA resulted in a success rate of approximately 50% when defined by both improvement in pain and physical function at 6-month follow-up. While the success rate was higher in the C-RFA group, this difference was not statistically significant. TRIAL REGISTRATION NUMBER: NCT02478437.

RESUMEN

Background and Objectives: Genicular nerve radiofrequency ablation is an effective treatment for patients with chronic pain due to knee osteoarthritis; however, little is known about factors that predict procedure success. The current study evaluated the utility of genicular nerve blocks to predict the outcome of genicular nerve cooled radiofrequency ablation (cRFA) in patients with osteoarthritis. Methods: This randomized comparative trial included patients with chronic knee pain due to osteoarthritis. Participants were randomized to receive a genicular nerve block or no block prior to cRFA. Patients receiving a prognostic block that demonstrated ≥50% pain relief for six hours received cRFA. The primary outcome was the proportion of participants with ≥50% reduction in knee pain at six months. Results: Twenty-nine participants (36 knees) had cRFA following a prognostic block, and 25 patients (35 knees) had cRFA without a block. Seventeen participants (58.6%) in the prognostic block group and 16 (64.0%) in the no block group had ≥50% pain relief at six months (P = 0.34). A 15-point decrease in the Western Ontario and McMaster Universities Osteoarthritis Index at six months was present in 17 of 29 (55.2%) in the prognostic block group and 15 of 25 (60%) in the no block group (P = 0.36). Conclusions: This study demonstrated clinically meaningful improvements in pain and physical function up to six months following cRFA. A prognostic genicular nerve block using a local anesthetic volume of 1 mL at each injection site and a threshold of ≥ 50% pain relief for subsequent cRFA eligibility did not improve the rate of treatment success.
