    Background: The rapid detection of Streptococcus pneumoniae could assist in the management of pneumococcal infections. The Binax NOW S. pneumoniae test is a rapid immunochromatographic test for this purpose. Methods: Multiplex PCR in parapneumonic pleural effusion fluid (PPEF) and cerebrospinal fluid (CSF) with Binax NOW urinary pneumococcal antigen test (PAT) from 80 children was compared in this study. Results: PAT had a sensitivity of 36.4%, specificity of 97.3%, in CSF. PAT had a sensitivity of 50%, specificity of 81% for parapneumonic pleural effusion fluid. Conclusions: When rapid management of a serious infection is needed the Binax NOW test could be a reliable method for the exclusion of S. pneumoniae infection.

    This multi-center point prevalence study evaluated children who were diagnosed as having coronavirus disease 2019 (COVID19). On February 2nd, 2022, inpatients and outpatients infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) were included in the study from 12 cities and 24 centers in Turkey. Of 8605 patients on February 2nd, 2022, in participating centers, 706 (8.2%) had COVID-19. The median age of the 706 patients was 92.50 months, 53.4% were female, and 76.7% were inpatients. The three most common symptoms of the patients with COVID-19 were fever (56.6%), cough (41.3%), and fatigue (27.5%). The three most common underlying chronic diseases (UCDs) were asthma (3.4%), neurologic disorders (3.3%), and obesity (2.6%). The SARS-CoV-2-related pneumoniae rate was 10.7%. The COVID-19 vaccination rate was 12.5% in all patients. Among patients aged over 12 years with access to the vaccine given by the Republic of Turkey Ministry of Health, the vaccination rate was 38.7%. Patients with UCDs presented with dyspnea and pneumoniae more frequently than those without UCDs (p < 0.001 for both). The rates of fever, diarrhea, and pneumoniae were higher in patients without COVID-19 vaccinations (p = 0.001, p = 0.012, and p = 0.027). Conclusion: To lessen the effects of the disease, all eligible children should receive the COVID-19 vaccine. The illness may specifically endanger children with UCDs.
