Review Comparative Study Clinical TrialDrug-induced sleep endoscopy in the obstructive sleep apnea: comparison between NOHL and VOTE classifications.
Obstructive sleep apnea (OSA) is characterized by recurrent episodes of partial or complete collapse of the pharynx that result in a decrease in oxyhemoglobin saturation. Nasofibrolaryngoscopy under induced sleep is a promising alternative for identifying sites of upper airway obstruction in patients with OSA. This study aimed to compare the obstruction sites screened by drug-induced sleep endoscopy (DISE) using the Nose oropharynx hypopharynx and larynx (NOHL) and Velum oropharynx tongue base epiglottis (VOTE) classifications. ⋯ Similar minimum SaO2 values were observed in DISE and PSG. The VOTE classification was more comprehensive in the analysis of the epiglottis and pharynx by DISE and the relationship between OSA severity and number of affected sites was also established by VOTE. The use of BIS associated with DISE is a reliable tool for the assessment of OSA patients.

ReviewOlfactory and gustatory dysfunctions due to the coronavirus disease (COVID-19): a review of current evidence.
It is reported that coronavirus disease (COVID-19) can affect the sense of smell and taste of infected people. The pathobiology of this virus is still incompletely known, and it is therefore important to explore the impact of COVID-19 infections on olfactory and gustatory functions. We aimed to review current evidence on olfactory and gustatory dysfunctions caused by COVID-19. ⋯ The results of our study support recent reports that SARS-CoV-2 may infect oral and nasal tissues and cause olfactory and gustatory dysfunctions. These findings may aid future research on the diagnosis, prevention, and treatment of COVID-19 consequences.

Incidence of intraglandular lymph nodes within submandibular gland, and involvement by floor of mouth cancer.
Resection of the submandibular gland is generally undertaken as an integral component of level I neck dissection for oral cancer. However, it is unclear whether lymph nodes are present within the submandibular gland which may form the basis of lymphatic spread. Our purpose was to investigate the frequency of lymph nodes within the submandibular gland, and the incidence and mechanism of submandibular gland involvement in floor of mouth cancer. ⋯ Mechanisms of involvement were direct extension, and by an apparent novel mechanism of carcinoma growing along bilateral Wharton's ducts. Despite the high incidence of level I metastasis in floor of mouth, lymphatic metastases to submandibular gland are unlikely based on absence of intraglandular lymph nodes. We describe a previously unreported mechanism of submandibular gland involvement.
