• Emergency Facial Injuries in Athletics. Clinics in sports medicine Tsao, J., Hwang, C. E. 2023; 42 (3): 463-471

  Abstract

  Dental and oral injuries are a common occurrence in sport. Initial evaluation should always begin with an assessment of the patient's airway, breathing, circulation, as well as identification of associated injuries. Tooth avulsions are the only true dental emergency. Oral lacerations frequently do not require repair; however, special attention should be paid to lip lacerations involving the vermillion border. Most tooth and oral lacerations can be treated on the field with urgent referral to a dentist.

• Prevalence of Positive Rapid Antigen Tests After 7-Day Isolation Following SARS-CoV-2 Infection in College Athletes During Omicron Variant Predominance. JAMA network open Tsao, J., Kussman, A., Segovia, N. A., Abrams, G. D., Boehm, A. B., Hwang, C. E. 2022; 5 (10): e2237149

  Abstract

  Importance: The US Centers for Disease Control and Prevention shortened the recommended isolation period for SARS-CoV-2 infection from 10 days to 5 days in December 2021. It is unknown whether an individual with the infection may still have a positive result to a rapid antigen test and potentially be contagious at the end of this shortened isolation period.Objective: To estimate the proportion of individuals with SARS-CoV-2 infection whose rapid antigen test is still positive starting 7 days postdiagnosis.Design, Setting, and Participants: This case series analyzed student athletes at a National Collegiate Athletic Association Division I university campus who tested positive for SARS-CoV-2 between January 3 and May 6, 2022. Individuals underwent rapid antigen testing starting 7 days postdiagnosis to determine whether they could end their isolation period.Exposures: Rapid antigen testing 7 days after testing positive for SARS-CoV-2.Main Outcomes and Measures: Rapid antigen test results, symptom status, and SARS-CoV-2 variant identification via campus wastewater analysis.Results: A total of 264 student athletes (140 [53%] female; mean [SD] age, 20.1 [1.2] years; range, 18-25 years) representing 268 infections (177 [66%] symptomatic, 91 [34%] asymptomatic) were included in the study. Of the 248 infections in individuals who did a day 7 test, 67 (27%; 95% CI, 21%-33%) tests were still positive. Patients with symptomatic infections were significantly more likely to test positive on day 7 vs those who were asymptomatic (35%; 95% CI, 28%-43% vs 11%; 95% CI, 5%-18%; P<.001). Patients with the BA.2 variant were also significantly more likely to test positive on day 7 compared with those with the BA.1 variant (40%; 95% CI, 29%-51% vs 21%; 95% CI, 15%-27%; P=.007).Conclusions and Relevance: In this case series, rapid antigen tests remained positive in 27% of the individuals after 7 days of isolation, suggesting that the Centers for Disease Control and Prevention-recommended 5-day isolation period may be insufficient in preventing ongoing spread of disease. Further studies are needed to determine whether these findings are present in a more heterogeneous population and in subsequent variants.
