ABSTRACT
Abstract Background Tuberous sclerosis (TS) is a multisystem genetic disease in which epilepsy is a frequent manifestation and is often difficult to control. Everolimus is a drug with proven efficacy in the treatment of other conditions related to TS, and some evidence suggests that its use benefits the treatment of refractory epilepsy in these patients. Objective To evaluate the efficacy of everolimus in controlling refractory epilepsy in children with TS. Methods A literature review was conducted in the Pubmed, BVS, and Medline databases, using the descriptors Tuberous sclerosis, Children, Epilepsy, and Everolimus. Original clinical trials and prospective studies published in Portuguese or English in the last decade that evaluated the use of everolimus as an adjuvant therapy in the control of refractory epilepsy in pediatric patients with TS were included. Results Our search screened 246 articles from electronic databases, 6 of which were chosen for review. Despite the methodological variations between the studies, most patients benefited from the use of everolimus to control refractory epilepsy, with response rates ranging from 28.6 to 100%. Adverse effects were present in all studies leading to dropouts of some patients; however, the majority were of low severity. Conclusion The selected studies suggest a beneficial effect of everolimus in the treatment of refractory epilepsy in children with TS, despite the adverse effects observed. Further studies involving a larger sample in double-blind controlled clinical trials should be performed to provide more information and statistical credibility.

BACKGROUND: Brazil is a middle-income country that aims to provide universal health coverage, but its surgical system's efficiency has rarely been analyzed. In an effort to strengthen surgical national systems, the Lancet Commission on Global Surgery proposed bellwether procedures as quality indicators of surgical workforces. This study aims to evaluate regional inequalities in access to bellwether procedures and their associated mortality across the five Brazilian geographical regions. METHODS: Using DATASUS, Brazil's national healthcare database, data were collected on the total amount of performed bellwether procedures-cesarean section, laparotomy, and open fracture management-and their associated mortality, by geographical region. We evaluated the years 2018-2020, both in emergent and elective conditions. Statistical analysis was performed by one-way ANOVA test and Tukey's multiple comparisons test. RESULTS: During this period, DATASUS registered 2,687,179 cesarean sections, 1,036,841 laparotomies, and 648,961 open fracture treatments. The access and associated mortality related to these procedures were homogeneous between the regions in elective care. There were significant geographical inequalities in access and associated mortality in emergency care (p < 0.05, 95% CI) for all bellwether procedures. The Southeast, the most economically developed region of the country, was the region with the lowest amount of bellwether procedures per 100,000 inhabitants. CONCLUSION: Brazil's public surgical system is competent at promoting elective surgical care, but more effort is needed to fortify emergency care services. Public policies should encourage equity in the geographic allocation of the surgical workforce.
