Approaches to nasal and oral decontamination with povidone-iodine (PVP-I) have been published to reduce nosocomial spread of Severe Acute Respiratory Syndrome-Coronavirus 2 (SARS-CoV-2). The safety of PVP-I topically applied to the nasal and oral cavity is addressed by a literature review. The specific efficacy of PVP-I against coronaviruses and its potential efficacy against SARS-CoV-2 is discussed. ⋯ Povidone-iodine can safely be used in the nose at concentrations up to 1.25% and in the mouth at concentrations up to 2.5% for up to 5 months. Povidone-iodine rapidly inactivates coronaviruses, including SARS and MERS, when applied for as little as 15 seconds. There is optimism that PVP-I can inactivate SARS-CoV-2, but in vitro efficacy has not yet been demonstrated.

Pharyngodynia, nasal congestion, rhinorrhea, smell, and taste dysfunctions could be the presenting symptoms of coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2. The aim was to perform a systematic review of current evidences on clinical presentation of COVID-19, focusing on upper airway symptoms in order to help otolaryngologists identifying suspected cases. ⋯ Otolaryngologists should know that pharyngodynia, nasal congestion, olfactory, and gustative disorders could be the presenting symptoms of COVID-19. Clinical presentation together with radiological and laboratory findings could help to identify suspected cases.

Review Case Reports
Unusual pseudomyiasis with Musca domestica (housefly) larvae in a tracheostomy wound: a case report and literature review.
We report a case of pseudomyiasis (accidental myiasis) in a 52-year-old man who had previously undergone surgery and placement of a tracheostomy tube for laryngeal cancer. The patient presented to our outpatient department with a foul-smelling, blood-stained discharge and frequent and severe episodic pain at the site of the tracheostomy. He also reported the discharge of many whitish larvae from the site. ⋯ We also discuss the need for the proper care of tracheostomy wound myiasis because the site of such an infestation is close to vital organs in the neck. To the best of our knowledge, only 3 cases of tracheostomy wound myiasis have been previously reported in the English-language literature; 2 of them involved infestation with Chrysomyia bezziana larvae and 1 with Lucilia caesar larvae. We believe our case is the first case of tracheostomy wound pseudomyiasis attributable to M domestica larvae.

Review Case Reports
Sphenopalatine artery pseudoaneurysm after endoscopic sinus surgery: a case report and literature review.
Previously reported cases of iatrogenic sphenopalatine artery (SPA) pseudoaneurysm have occurred only after trans-sphenoidal surgery for pituitary tumors or maxillofacial surgery. In this article, the author presents what to the best of her knowledge is the first reported case of an SPA pseudoaneurysm that developed following endoscopic sinus surgery (ESS). The patient was a 76-year-old woman with myelodysplastic syndrome who presented with a 6-month history of unilateral sinus symptoms. ⋯ The pathogenesis may include intraoperative trauma, infection, pressure necrosis from packing, or a combination of these factors. Optimal management includes either ligation or embolization, depending on anatomic, patient, staff, and resource factors. The author reviews the pertinent anatomy and the pathophysiology, diagnosis, management, and prevention of this rare complication.
