The researchers also took swabs from inside the nose - much like a COVID-19 test - from each child and tested for the three main types of bacteria involved in sinusitis. and randomly assigned them to receive either a course of antibiotics or placebo. With the goal of developing a better tool to diagnose bacterial sinusitis, Shaikh and his team enrolled about 500 children with sinusitis symptoms from six centers across the U.S. But for sinusitis, we have nothing to go on from a physical exam.

Sinusitis, which is an inflammation or swelling of the sinuses, can cause congestion, runny nose, discomfort and difficulty breathing. "Our study suggests that only half of these kids see an improvement in symptoms with antibiotic use, so by identifying who they are, we could greatly reduce unnecessary antibiotic use." get prescribed antibiotics for sinusitis each year," said lead author Nader Shaikh, M.D., pediatrician at UPMC Children's Hospital of Pittsburgh and professor of pediatrics and clinical and translational science at Pitt.
