Arthroscopically Assisted Reduction and Internal Fixation of Talar Neck Fracture: A Case Report.

Introduction: Arthroscopic-assisted reduction and internal fixation (ARIF) is a recent concept and is increasingly used for articular fractures, due to the minimally invasive nature and high accuracy. However, there are few reports in literature about this procedure in talar fractures.

Case Report: The authors describe a clinical case of a 22-year-old woman with a closed right articular talar neck fracture, Hawkins type II, treated with arthroscopically ARIF.

Duration of post-vaccination humoral immunity against yellow fever in children.

Introduction: Vaccination is the most important measure for prevention and control of yellow fever. It is recommended by the World Health Organization (WHO) for residents of endemic areas and travelers to risk areas. In 2013, the WHO discontinued the recommendation of booster doses every 10 years, indicating a single dose as sufficient for lifelong protection.

Cytokine signatures of innate and adaptive immunity in 17DD yellow fever vaccinated children and its association with the level of neutralizing antibody.

Background: The live attenuated yellow fever (YF) vaccines have been available for decades and are considered highly effective and one of the safest vaccines worldwide.

Methods: The impact of YF-17DD-antigens recall on cytokine profiles of YF-17DD-vaccinated children were characterized using short-term cultures of whole blood samples and single-cell flow cytometry. This study enrolled seroconverters and nonseroconverters after primovaccination (PV-PRNT⁺ and PV-PRNT⁻), seroconverters after revaccination (RV-PRNT⁺), and unvaccinated volunteers (UV-PRNT⁻).
