RESUMO

ETHNOPHARMACOLOGICAL RELEVANCE: Cuphea is the largest genus of the Lythraceae family. It is popularly known as "sete-sangrias" in Brazil used in folk medicine as a diuretic, antipyretic, anti-inflammatory, laxative and antihypertensive agent. The raw material of Cuphea has shown promising results in the production of fitotherapics, which are chemically characterized by quercetin core flavonoids. AIMS OF THE STUDY: Present work aims to investigate the chemical composition of Cuphea calophylla, Cuphea carthagenensis, Cuphea glutinosa and Cuphea racemosa by UHPLC-MS using ESI-Q-TOF, and also to investigate the inhibition of angiotensin-converting enzyme (ACE) in vitro. MATERIALS AND METHODS: Leaves extraction was conducted by an ultrasound-assisted system under the following conditions: 40% ethanol, particle size ≤180 µm, plant:solvent ratio 1:20 (w/v) for 30 min. The leaf extracts were analyzed by UHPLC-MS positive mode ionization. For the inhibition of ACE, the leaf extracts used were obtained from different Cuphea species collected from several regions of Rio Grande do Sul (Brazil). RESULTS: In total 26 polyphenolic compounds were proposed, which were mostly derived from quercetin, myricetin, and kaempferol. Of these compounds, ten are described in the genus for the first time. The ACE-inhibiting activities are presented in descending order: miquelianin (32.41%), C. glutinosa 1 (31.66%), C. glutinosa 5 (26.32%) and C. carthagenensis 1 (26.12%). CONCLUSION: The obtained results suggest that the ACE-inhibiting potential may be increased by the interactions among the different phytoconstituents present in the crude extract. These results corroborate with the popular usage of Cuphea genus as diuretic and antihypertensive agents in folk medicine.

RESUMO

OBJECTIVE: Cleft palate increases the risk of chronic middle ear disease and hearing loss. The goal of this report was to determine which of two palate surgeries and which timing of palate surgery were associated with better otologic and audiologic outcomes in children with unilateral cleft lip and palate at 5 to 6 years of age. DESIGN: Subjects were randomly assigned to the von Langenbeck with intravelar veloplasty or Furlow palate repair, to palate surgery at 9 to 12 months or 15 to 18 months of age, and to the Spina or Millard lip repair. SETTING: Centralized, tertiary care craniofacial treatment center. PATIENTS: A total of 673 infants with unilateral cleft lip and palate. INTERVENTIONS: Palate and lip were repaired using established techniques. Serial otoscopic and audiometric evaluations were performed. MAIN OUTCOME MEASURES: Hearing and otoscopic findings at 5 to 6 years old. RESULTS: There were 370 children available for analysis. Hearing and need for tympanostomy tube placement did not differ by palatoplasty, age at palatoplasty, cheiloplasty, or surgeon. Risk of developing cholesteatoma or perforation was higher with Millard cheiloplasty (odds ratio  =  5.1, 95% confidence interval  =  1.44 to 18.11, p  =  .012). Type and age at palatoplasty were not significantly associated with either the rate of developing these sequelae or the rate of achieving bilaterally normal hearing and ear examinations. CONCLUSIONS: Type of palatoplasty did not influence otologic and audiologic outcomes in 5- to 6-year-olds with unilateral cleft lip and palate. The potential influence of lip repair on otologic outcomes warrants further investigation.

RESUMO

The goal of this prospective randomized clinical trial was to compare 2 cohorts of standardized cleft patients with regard to functional speech outcome and the presence or absence of palatal fistulae. The 2 cohorts are randomized to undergo either a conventional von Langenbeck repair with intravelar velarplasty or the double-opposing Z-plasty Furlow procedure. A prospective 2 × 2 × 2 factorial clinical trial was used in which each subject was randomly assigned to 1 of 8 different groups: 1 of 2 different lip repairs (Spina vs. Millard), 1 of 2 different palatal repair (von Langenbeck vs. Furlow), and 1 of 2 different ages at time of palatal surgery (9-12 months vs. 15-18 months). All surgeries were performed by the same 4 surgeons. A cul-de-sac test of hypernasality and a mirror test of nasal air emission were selected as primary outcome measures for velopharyngeal function. Both a surgeon and speech pathologist examined patients for the presence of palatal fistulae. In this study, the Furlow double-opposing Z-palatoplasty resulted in significantly better velopharyngeal function for speech than the von Langenbeck procedure as determined by the perceptual cul-de-sac test of hypernasality. Fistula occurrence was significantly higher for the Furlow procedure than for the von Langenbeck. Fistulas were more likely to occur in patients with wider clefts and when relaxing incisions were not used.
