Objective: To present a new dexamethasone mouthwash formulation and  analyze its effectiveness and safety among patients receiving stomatitis-producing antineoplastic agents.

Method: Prospective observational study conducted in a university hospital between March 2017 and November 2019. Consecutive patients starting everolimus were enrolled. Patients were instructed to rinse dexamethasone mouthwash formulation twice daily until discontinuation of everolimus. A second cohort of patients with existing stomatitis induced by  high probability of producing stomatitis chemotherapy therapies was also  recruited to assess treatment effectiveness. Effectiveness and safety of dexamethasone mouthwash formulation was assessed.

Results: Dexamethasone mouthwash formulation was prescribed in nine patients as prophylaxis. Six patients were diagnosed with breast cancer, two with neuroendocrine tumor and one with renal cell carcinoma. Four patients developed mild stomatitis (grade 1-2) and three patients  discontinued everolimus due to other treatment-related adverse events. In  addition, dexamethasone mouthwash formulation was prescribed as treatment in five patients with existing stomatitis. All patients achieved a significant reduction in the severity of stomatitis after starting the  dexamethasone mouthwash formulation. In both cohorts, dexamethasone  mouthwash formulation was well tolerated and neither dose reduction nor  discontinuation related to stomatitis was required.

Conclusions: Dexamethasone mouthwash formulation could be considered as a  suitable alternative for stomatitis management.

Early childhood caries (ECC), a severe form of dental caries, is exacerbated by the synergistic interaction between Streptococcus mutans and Candida albicans, leading to greater disease severity than their individual effects. This underscores the need for more targeted and potent therapeutic alternatives. Given the promising anti-infective properties of quaternary ammonium surfactants (QAS), this study explores the microbicidal properties of one such QAS, cetyltrimethylammonium chloride (CTAC), against both individual- and dual-species cultures of S.

Objectives: Daily-use fluoride products are first-line protection against enamel wear from dietary-acid exposure (DAE). This study aimed to understand effects of fluoride concentration, fluoride salt, product form and ingredients in daily-use products on remineralisation and demineralisation, via network meta-analysis (NMA) of 14 studies using one well-established in-situ model. Remineralisation (surface-microhardness recovery, SHMR) after treatment, and protection against subsequent demineralisation (acid-resistance ratio, ARR) were measured.

Background: Impression materials can harbour microorganisms from saliva and blood, posing cross-contamination risks. However, post-setting disinfection might compromise the dimensional accuracy and mechanical properties of alginates. Hence, it was the aim of this research to assess the detail reproduction, tear strength, elastic recovery, and surface quality of the gypsum model of newly developed dental alginates with inherent antimicrobial properties.

Unlabelled: For the past few years, the synthesis of zinc oxide (ZnO) and other metal oxide nanoparticles has been carried out using plant tissues, extracts, and other plant parts. The green synthesis of zinc oxide nanoparticles has many advantages over other processes, and the primary areas of application are drug delivery, food additives, and surface coatings. The use of nanoparticles as an alternative antimicrobial agent in the health and biomedical sectors has increased significantly in recent years.

Molecular Insights into the Penetration Enhancement Mechanism of Terpenes to Skin.

Key Lab of Colloid and Interface Chemistry, Shandong University, Jinan, Shandong 250100, P.R. China.

Article Synopsis
  • Terpenes, often used in cosmetics as enhancers, help improve skin penetration through their effects on lipid membranes, but the exact mechanisms were not fully understood until this study.
  • Molecular dynamics simulations were conducted to assess how terpineol, 1,8-cineole, and limonene interacted with skin layers, revealing that they affect cholesterol and lipid structure differently.
  • The study found that limonene penetrates best due to its unique ability to create a "triple layer" membrane and that terpenes can lower energy barriers for other molecules to cross skin, providing new insights into enhancing skin penetration in cosmetic formulations.
