Neurilemoma (schwannoma) is the most commonly encountered nerve sheath tumor of the oral cavity. It generally appears as a single encapsulated nodule that occasionally causes pain or discomfort. The tongue is involved most frequently, followed by the palate, floor of mouth, and buccal mucosa. Neurilemomas occur most often during the second or third decades of life. Our patient is a 21-year-old woman with a recurrence of a palatal mass that was excised 3 years earlier. Histologically the lesion appeared to be a multinodular neurilemoma, a pattern rarely reported in the oral cavity.

Airway pressures generated by high flow nasal cannula in patients with acute hypoxemic respiratory failure: a computational study.

Introduction And Objectives: High flow nasal cannula (HFNC) therapy is an increasingly popular mode of non-invasive respiratory support for the treatment of patients with acute hypoxemic respiratory failure (AHRF). Previous experimental studies in healthy subjects have established that HFNC generates flow-dependent positive airway pressures, but no data is available on the levels of mean airway pressure (mP) or positive end-expiratory pressure (PEEP) generated by HFNC therapy in AHRF patients. We aimed to estimate the airway pressures generated by HFNC at different flow rates in patients with AHRF, whose functional lung volume may be significantly reduced compared to healthy subjects due to alveolar consolidation and/or collapse.

Background: Oral infectious diseases, such as dental caries, periodontitis and periapical periodontitis, are often complicated by causative bacterial biofilm formation and significantly impact human oral health and quality of life. Bacteriophage (phage) therapy has emerged as a potential alternative with successful applications in antimicrobial trials. While therapeutic use of phages has been considered as effective treatment of some infectious diseases, related research focusing on oral infectious diseases is few and lacks attention.

Various interventions are available for the management, of which microinvasive techniques such as infiltration, sealants, glass ionomers, are novel and convenient. The purpose of this systematic review and meta-analysis was to compare microinvasive techniques with noninvasive or invasive treatment modalities in terms of effectiveness in halting interproximal caries lesion progression radiographically assessed.

Increasing evidence suggests that interlocutors use visual communicative signals to form predictions about unfolding utterances, but there is little data on the predictive potential of facial signals in conversation. In an online experiment with virtual agents, we examine whether facial signals produced by an addressee may allow speakers to anticipate the response to a question before it is given. Participants (n = 80) viewed videos of short conversation fragments between two virtual humans.

Objectives: This cross-sectional study aimed to evaluate the occurrence of Streptococcus spp., Streptococcus mutans, its serotypes (c, e, f, and k), collagen-binding genes (cnm/cbm), and Candida albicans in medium deep (D2) and deep (D3) dentin carious lesions of permanent teeth.
Materials And Methods: Carious dentin was collected from D2 (n = 23) and D3 (n = 24) lesions in posterior teeth from 31 individuals.
