Comparison of antigen test and polymerase chain reaction for SARS-CoV-2 in children younger than 12 years.

Stopping the spread of coronavirus disease 2019 (COVID-19) is critical and can be achieved through rapid and effective detection techniques. Our objective was to compare the diagnostic accuracy of rapid antigen tests (RAgT) and reverse transcriptionquantitative polymerase chain reaction (RT-qPCR) and to describe amplification cycle thresholds (Cts). Participants were children aged 1 month to 11 years with symptoms for less than 7 days, who did not have a detectable result in the past 90 days, and were immunocompetent.

Introduction: In 2019, a new infection was reported in China. This coronavirus was named SARS-COV-2, causative of the 21st-century pandemic, COVID-19. Health systems adopted different strategies to cope with it.

Post-bleaching sensitivity in patients with sickle cell disease.

Sickle cell disease (SCD) is a monogenic disease that affects millions of people worldwide. This study analyzed the effectiveness of bleaching and tooth sensitivity after in-office bleaching in patients with SCD. Forty volunteers were randomly assigned to four groups of 10 patients each (five with the SCD and five healthy controls) and treated using in-office bleaching with 35% hydrogen peroxide and different light activation protocols.

Acute otitis media is the most common bacterial infection in children. Despite efficient antibiotic therapy, there are still reports of both intratemporal and intracranial complications with potential risk of high morbidity and mortality. Mastoiditis, apical petrositis and labyrinthitis are caused by the extension of purulent middle ear infection into nearby structures.
