Disseminated Nonsegmental Vitiligo Associated With Halo Nevi and Premature Gray Hair [Case Report]
Ramachandran, Vignesh; Kim, Katelyn M; Zhang, Lisa
Halo nevi (HN) are acquired melanocytic nevi circumferentially surrounded by a depigmented patch. HN are commonly associated with vitiligo and can be associated with uveal, mucosal, or cutaneous melanoma in certain patient populations. HN may also have localized leukotrichia of terminal hair overlying the nevus. We report a less common triad of rapid-onset HN, nonsegmental vitiligo, and premature hair graying (PHG) of scalp hair.

Efficacy of quality improvement and patient safety workshops for students: a pilot study
Shah, Kevin P; Goyal, Shreya; Ramachandran, Vignesh; Kohn, Jaden R; Go, Jonathan A; Wiley, Zachary; Moturu, Anoosha; Namireddy, Meera K; Kumar, Anjali; Jacobs, Ryan C; Stampfl, Matthew; Shah, Jesal R; Fu, Justin; Lin, Weijie V; Ho, Brandon; Wey, Grace; Lin, Sophie Y; Caruso, Andrew C; Gay, Lindsey Jordan; Stewart, Diana E; Andrabi, Sara
BACKGROUND:While the Association of American Medical Colleges encourages medical schools to incorporate quality improvement and patient safety (QI/PS) into their curriculum, medical students continue to have limited QI/PS exposure. To prepare medical students for careers that involve QI/PS, the Institute for Healthcare Improvement chapter at an allopathic medical school and school of allied health professions initiated self-directed learning by offering student-led workshops to equip learners with skills to improve the quality and safety of healthcare processes. METHODS:In this prospective cohort study, workshops were hosted for medical students between 2015 and 2018 on five QI/PS topics: Process Mapping, Root-Cause Analysis (RCA), Plan-Do-Study-Act (PDSA) Cycles, Evidence Based Medicine (EBM), and Patient Handoffs. Each workshop included a hands-on component to engage learners in practical applications of QI/PS skills in their careers. Change in knowledge, attitudes, and behaviors was assessed via pre- and post-surveys using 5-point Likert scales, and analyzed using either the McNemar test or non-parametric Wilcoxon signed-rank test. Surveys also gathered qualitative feedback regarding strengths, future areas for improvement, and reasons for attending the workshops. RESULTS:Data was collected from 88.5% of learners (n = 185/209); 19.5% of learners reported prior formal instruction in these topics. Statistically significant improvements in learners' confidence were observed for each workshop. Additionally, after attending workshops, learners felt comfortable teaching the learned QI/PS skill to colleagues (mean pre/post difference 1.96, p < 0.0001, n = 139) and were more likely to pursue QI/PS projects in their careers (mean pre/post difference 0.45, p < 0.0001, n = 139). Lastly, learners demonstrated a statistically significant increase in knowledge in four out of five skills workshop topics. CONCLUSION/CONCLUSIONS:Few medical students have formal instruction in QI/PS tools. This pilot study highlights advantages of incorporating an innovative, student-directed modified 'flipped classroom' methodology, with a focus on active experiential learning and minimal didactic instruction.

Association between pemphigus and psoriasis: a systematic review and meta-analysis [Letter]
Phan, Kevin; Ramachandran, Vignesh; Smith, Saxon D
Pemphigus has been associated with other autoimmune and autoinflammatory disorders. Specifically, some case reports in the literature document coexistence of pemphigus with psoriasis, but this association is lacking larger scale investigation. With this in mind, we conducted a systematic review and meta-analysis to evaluate the association between pemphigus and psoriasis. In doing so, we found an association between the two conditions. Pemphigus was more common in patients with psoriasis than in controls (OR 2.64, 95% CI 1.24-5.59, P=0.01), with heterogeneity (I2=94%). We go on to propose pathophysiologic mechanisms and its relevance for diagnostic and management considerations.

Crew-Friendly Countermeasures Against Musculoskeletal Injuries in Aviation and Spaceflight
O'Conor, Daniel K; Dalal, Sawan; Ramachandran, Vignesh; Shivers, Bethany; Shender, Barry S; Jones, Jeffrey A
Aviation and space medicine face many common musculoskeletal challenges that manifest in crew of rotary-wing aircraft (RWA), high-performance jet aircraft (HPJA), and spacecraft. Furthermore, many astronauts are former pilots of RWA or HPJA. Flight crew are exposed to recurrent musculoskeletal risk relating to the extreme environments in which they operate, including high-gravitational force equivalents (g-forces), altered gravitational vectors, vibratory loading, and interaction with equipment. Several countermeasures have been implemented or are currently under development to reduce the magnitude and frequency of these injuries. Cervical and lumbar spine, as well as extremity injuries, are common to aviators and astronauts, and occur in training and operational environments. Stress on the spinal column secondary to gravitational loading and unloading, ± vibration are implicated in the development of pain syndromes and intervertebral disk pathology. While necessary for operation in extreme environments, crew-support equipment can contribute to musculoskeletal strain or trauma. Crew-focused injury prevention measures such as stretching, exercise, and conditioning programs have demonstrated the potential to prevent pre-flight, in-flight, and post-flight injuries. Equipment countermeasures, especially those addressing helmet mass and center of gravity and spacesuit ergonomics, are also key in injury prevention. Furthermore, behavioral and training interventions are required to ensure that crew are prepared to safely operate when faced with these exposures. The common operational exposures and risk factors between RWA and HPJA pilots and astronauts lend themselves to collaborative studies to develop and improve countermeasures. Countermeasures require time and resources, and careful consideration is warranted to ensure that crew have access to equipment and expertise necessary to implement them. Further investigation is required to demonstrate long-term success of these interventions and inform flight surgeon decision-making about individualized treatment. Lessons learned from each population must be applied to the others to mitigate adverse effects on crew health and well-being and mission readiness.

Does it match? Analyzing self-reported online dermatology match data to Charting Outcomes in the Match
Ramachandran, Vignesh; Nguyen, Hai-Yen; Dao, Harry
Dermatology is arguably the most competitive residency (81.6% match rate for United States allopathic seniors) with significantly more applicants than available positions. To objectify this process, the National Residency Match Program (NRMP) has produced bi-annual Charting Outcomes in Match (COM) datasets, which aggregate data from the prior two application cycles and tabulate statistics to aid applicants. In parallel, online forums provide medical trainees with vast amounts of information, including residency application insights. Reddit medical school subforum compiles annual spreadsheets of anonymous, individualized applicant data to aid future applicants. We compared this data to NRMP data to show that although the data means are similar (e.g. Step 1), the Reddit dermatology spreadsheet collects more data and the individualized nature aids applicants in a personalized way unlike the mean aggregate data in NRMP. Under univariate analysis, Alpha Omega Alpha status, overall publications, and dermatology-specific publications are associated with interview invitation rates. Although limitations of the study include small data size and reporting bias, this is the first of its kind to our knowledge to compare these two often-used tools to aid dermatology applicants. Future endeavors should expand anonymous data reporting and use the data to carry out more extensive studies to investigate factors influencing the application process.
