Safety and efficacy of a 100% dimethicone pediculocide in school-age children.

BACKGROUND: Head lice most commonly affect children, ages 3 to 11. Concerns exist about the safety and efficacy of pesticide-based treatments. Published studies suggest dimethicone is a potentially safe and effective non-toxic treatment, but have not evaluated 100% dimethicone in a pediatric population. The objectives were to evaluate the efficacy and safety of 100% dimethicone for the treatment of head lice in children, monitored by school nurses. METHODS: This was a multi-site, open-label study of a 100% dimethicone gel for the treatment of head lice in a pediatric population. Children (ages 3-12) suspected of infestation with head lice were evaluated by school nurses at six schools and daycare programs in New York and New Jersey. Inclusion criteria were presence of at least three live lice, or one live louse and 10 viable eggs (eggs found within 1.27 cm of the scalp) and no use of any head lice treatment within four weeks of enrollment. Counts of live lice and viable eggs found in 58 subjects were tracked at baseline (Day 0) and on Day 1, Day 7, and Day 14 after treatment. RESULTS: After 1 day of treatment with 100% dimethicone, 98.30% of subjects were free of live lice and 55.20% were free of viable eggs. On day 14, 96.50% were still free of live lice, and 80.70% were free of viable eggs. All subjects were monitored by the school nurse at baseline and throughout the study period for adverse effects, including scalp erythema, excoriation, flaking and edema. There was one adverse event of skin irritation lasting 10 min, and no serious adverse events reported. Overall, scalp conditions improved from the baseline: 10 subjects (17.5%) reported mild to moderate scalp erythema on day 1, compared with only one subject (1.7%) on day 14; 8 subjects (14.3%) reported mild scalp excoriation on day 1, with none reporting on day 14. CONCLUSIONS: 100% dimethicone was found to be a safe and highly effective treatment for pediatric head lice. Because dimethicone avoids pesticide exposure and resistance issues, dimethicone should be considered as a first-line treatment for head lice.

Medical Students on the Virtual Front Line: A Literature Review Elective to Provide COVID-19 Clinical Teams With Essential Information.

PROBLEM: At the Hackensack Meridian School of Medicine (HMSOM) in New Jersey, clinical activities for students were suspended on March 15, 2020, due to the COVID-19 pandemic. Clinical teams at Hackensack Meridian Health (HMH) needed resources for identifying and assimilating the medical literature regarding COVID-19, which was expanding and evolving daily. HMH leaders reached out to HMSOM leaders for assistance. The HMSOM leadership and faculty quickly organized a literature review elective. APPROACH: Eight second-year medical students participated in a literature review elective course to research and synthesize the COVID-19 clinical literature to provide synopses of best practices for various clinical teams. By March 23, students were searching the literature and writing reports independently, mentored by a senior dean (an infectious diseases specialist) and supported by the associate dean of libraries and library team. The library team updated and categorized student reports daily on a website dedicated to the elective. OUTCOMES: During the 6-week elective, 8 students produced 70 reports synthesizing the emerging COVID-19 literature to help answer practitioners' clinical questions in real time. One student report was posted on the American Academy of Ophthalmology website. All 70 were published online in Elsevier's health education faculty hub. On course evaluations, students expressed regret about not being directly involved in patient care but articulated their gratitude to be able to contribute to the clinical teams. NEXT STEPS: In June 2020, the students returned to their clinical clerkships as COVID-19 clinical volumes declined and personal protective equipment became more available. Students continued to be available to the clinical teams to assist with COVID-19 questions. This literature review elective can serve as a model for other medical schools to use to deploy students to help synthesize the evolving literature on COVID-19 or other rapidly emerging research topics.
