Anesthetic Management of a Patient With a Giant Hemangioma Who Required Urgent Embolization for Bleeding During Third Molar Extractions.

Hemangiomas in the head and neck region, especially those that may impact the airway, require special attention perioperatively because of the potential for difficulties with airway management and bleeding control. This case report describes the management of a 31-year-old male with a large hemangioma of the tongue and pharynx undergoing surgical extraction of mandibular third molars under intubated general anesthesia. Despite taking precautions and avoiding traumatizing the hemangioma while securing the airway, massive bleeding occurred during the surgical extractions, which prompted emergent transfer for angiographic embolization and a stay in the intensive care unit until extubation.

SARS-CoV-2 recombinant proteins-induced degeneration of taste buds in rat circumvallate papillae.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infections cause loss or alteration of taste and smell as early symptoms and sequelae, but the detailed mechanism remains unclear. This study investigated whether coronavirus disease 2019-induced taste disorders are caused by direct effects on taste bud cells. SARS-CoV-2 recombinant spike and nucleocapsid proteins were applied to circumvallate papillae of male Sprague-Dawley rats.
