Clinical and Laboratory Comparison of Covid-19 and Influenza A/B in Children.

Background: The clinical picture of COVID-19 shows significant similarity with influenza. In this study, it was aimed to compare the clinical and laboratory findings between pediatric patients diagnosed with COVID-19 and those with influenza A or B, and to obtain data on the differential diagnosis of COVID-19 from influenza in children.

Methods: The study included 104 patients with COVID-19, 140 patients with influenza A and 135 patients with in-fluenza B (379 patients in total) who were admitted to our tertiary hospital with symptoms of acute respiratory tract infection.

The Importance of Neutrophil/Lymphocyte and Lymphocyte/Monocyte Ratios in The Diagnosis of Influenza in Children.

Background: We aimed to analyze the neutrophil/lymphocyte ratio (NLR) and lymphocyte/monocyte ratio (LMR) to investigate their value in supporting the diagnosis of influenza in cases with influenza-like symptoms.

Methods: A total of 5,693 pediatric patients who applied to the Pediatric Clinic between January 2015 and December 2018 were included in the study. Complete blood count and influenza rapid antigen tests were evaluated at the time of admission.

Evaluation of Patterns of Presentation, Practice, and Outcomes of Upper Tract Urothelial Cancer: Protocol for an Observational, International, Multicenter, Cohort Study by the Clinical Research Office of the Endourology Society.

Background: Available guidelines on the management of upper tract urothelial carcinoma (UTUC) are restricted due to the lack of strong evidence-based recommendations. Adequate, well-powered randomized trials are missing due to the rarity of the disease. To overcome this problem, we need alternative study designs to provide generalizable data.
