Efficacy, immunogenicity and safety of a recombinant tetravalent dengue vaccine (CYD-TDV) in children aged 2-17 years: systematic review and meta-analysis.

Background: Randomised controlled trials have evaluated the recombinant tetravalent dengue vaccine (CYD-TDV). However, individual results may have little power to identify differences among the populations studied.

Objective: To evaluate efficacy, immunogenicity and safety of CYD-TDV in the prevention of dengue in children aged 2-17 years.

Compartment surgery in treatment strategies for retroperitoneal sarcomas: a single-center experience.

Background: Retroperitoneal sarcomas (RPS) are rare tumors and radical surgery is still the only curative treatment. We aim to estimate postoperative morbidity and mortality and identify significant prognostic factors for survival of patients with RPS and then evaluate the effect of en bloc resection on survival.

Methods: This was a retrospective follow-up study of 91 patients with RPS who underwent surgery at the Section of Abdominopelvic Surgery of the National Cancer Institute-Brazil (INCA) between June 1992 and January 2008.
