Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is primarily transmitted person-to-person through the aerosolization of droplets containing contaminated nasopharyngeal secretions. 1 Povidone iodine (PI) solutions at concentrations as low as 0.5% rapidly inactivate SARS-CoV-2 in vitro with contact times as short as 15 seconds. 2 We investigated whether nasopharyngeal application of PI could reduce the viral load of patients with nonsevere coronavirus disease 2019 (COVID-19) symptoms.

OBSERVATION Adolescent Presentation of Nasal Chondromesenchymal Hamartoma: A Case Report and Literature Review Nasal chondromesenchymal hamartoma (NCMH) is a very rare benign tumor of the nasal cavity and paranasal sinuses that usually presents in infancy. These tumors may be expansile and locally destructive. The etiology has remained unclear, but it has been linked in the past to pleuropulmonary blastoma as
