Severe oral mucositis relating to pain and worse oral condition among patients with solid tumors undergoing treatment with FOLFIRI and 5-FU: a retrospective study.

Background: There is a need for studies that correlate the severity of oral mucositis (OM) with chemotherapy protocols, transient myelosuppression and oral health.

Objective: To analyze the severity of OM among individuals with solid tumors during hospitalization and its correlation with the type of chemotherapy, myelosuppression and oral health condition.

Design And Setting: Retrospective study at a public hospital in Bauru, state of São Paulo, Brazil, that is a regional referral center.

Chemical Composition, Larvicidal Activity, and Enzyme Inhibition of the Essential Oil of Schauer from the Caatinga Biome against Dengue Vectors.

Insect resistance and environmental pollution are among the drawbacks of continuous use of synthetic insecticides against the vectors of dengue, and . The objective of this study was to analyze the composition of the essential oil of Schauer collected from plants, in three periods of the year, to compare the larvicidal activity and enzymatic inhibition of the dengue vectors. The oilsanalyzed by gas chromatography coupled to mass spectrometry (GC-MS), presented thymol and 1,8-cineole, as the main constituents, in all three periods.
