Dental infections may lead to severe local or systemic infections such as endocarditis, brain abscesses and mediastinitis. Fever may be the only symptom. We aim to highlight dental/odontogenic abscesses as the occult source of unexplained fever by reporting on three cases and reviewing the relevant literature.

Indirect laryngoscopic assessment for the diagnosis of difficult intubation in patients undergoing microlaryngeal surgery.

Background: The aim of this study is to investigate the feasibility of using indirect laryngoscopy for the diagnosis of difficult intubations in patients who are undergoing microlaryngeal surgery.
