RESUMO
PURPOSE: The present randomized controlled clinical trial evaluated the efficacy of homeopathic medicines of Melissa officinalis (MO), Phytolacca decandra (PD), and the combination of both in the treatment of possible sleep bruxism (SB) in children. STUDY DESIGN: Patients (nâ¯=â¯52) (6.62 ± 1.79 years old) were selected based on the parents report of SB. The study comprised a crossover design that included 4 phases of 30-day treatment (Placebo; MO 12c; PD 12c; and MO 12c + PD 12c), with a wash-out period of 15 days between treatments. METHODS: At baseline and after each phase, the Visual Analogic Scale (VAS) was used as the primary outcome measure to evaluate the influence of treatments on the reduction of SB. The following additional outcome measures were used: a children's sleep diary with parent's/guardian's perceptions of their children's sleep quality, the trait of anxiety scale (TAS) to identify changes in children's anxiety profile, and side effects reports. Data were analyzed by ANOVA with repeated measures followed by Post Hoc LSD test. RESULTS: Significant reduction of SB was observed in VAS after the use of Placebo (-1.72 ± 0.29), MO (-2.36 ± 0.36), PD (-1.44 ± 0.28) and MO + PD (-2.21 ± 0.30) compared to baseline (4.91 ± 1.87). MO showed better results compared to PD (pâ¯=â¯0.018) and Placebo (pâ¯=â¯0.050), and similar result compared to MO+PD (pâ¯=â¯0.724). The sleep diary results and TAS results were not influenced by any of the treatments. No side effects were observed after treatments. CONCLUSION: MO showed promising results in the treatment of possible sleep bruxism in children, while the association of PD did not improve MO results.

Ilex paraguariensis (maté) is one of the best sources of chlorogenic acids (CGA) in nature. When leaves are toasted, some isomers are partly transformed into 1,5-γ-quinolactones (CGL). Both CGA and CGL are important contributors to the brew's flavor and are thought to contribute to human health. In this study, we quantified 9 CGA, 2 CGL, and caffeic acid in 20 samples of dried green and toasted maté that are commercially available in Brazil. Total CGA content in green maté varied from 8.7 to 13.2 g/100 g, dry weight (dw). Caffeic acid content varied from 10.8 to 13.5 mg/100 g dw, respectively. Content in toasted maté varied from 1.5 to 4.6 g/100 g and from 1.5 to 7.2 mg/100 g dw, respectively. Overall, caffeoylquinic acid isomers (CQA) were the most abundant CGA in both green and toasted maté, followed by dicaffeoylquinic acids (diCQA) and feruloylquinic acids (FQA). These classes accounted for 58.5%, 40.0%, and 1.5% of CGA, respectively, in green maté and 76.3%, 20.7%, and 3.0%, respectively, in toasted maté. Average contents of 3-caffeoylquinolactone (3-CQL) and 4-caffeoylquinolactone (4-CQL) in commercial toasted samples were 101.5 mg/100 g and 61.8 mg/100 g dw, respectively. These results show that, despite overall losses during the toasting process, CGA concentrations are still substantial in toasted leaves, compared to other food sources of CGA and phenolic compounds in general. In addition to evaluating commercial samples, investigation of changes in CGA profile and formation of 1,5-γ-quinolactones was performed in experimental maté toasting.
