Abstract :Aim: Epistaxis may be a symptom of an inherited bleeding disease.. We aimed to analyze an approved pediatric bleeding score insert ignore into journalissuearticles values(PBS); as a screening test for von Willebrand Disease insert ignore into journalissuearticles values(VWD); in children with epistaxis Material and Method: We retrospectively reviewed the medical records of pediatric patients, who applied to the Pediatric Hematology Department with the complaint of epistaxis between January 2018 and December 2019. Results: One hundred and sixty eight patients enrolled in this study There were 65insert ignore into journalissuearticles values(38.7%); girls and 103insert ignore into journalissuearticles values(61.3%); boys, with a mean age of 114±49 months insert ignore into journalissuearticles values(range 8 months to 18 years);.The PBS of 34 patients was greater than/ or equal to 2. Factor 8, von Willebrand factor antigen, and von Willebrand Ristocetin cofactor levels were significantly lower in patients with PBS≥2 compared to those in patients with PBS<2 insert ignore into journalissuearticles values(%73±43 vs % 91±29, p=0.03; 87±44 vs 106±29 IU/dl, p=0.03; 72±39 vs 98±30 IU/dl, p=0.001, respectively);. While 15 insert ignore into journalissuearticles values(44%); of 34 patients with PBS ≥ 2 diagnosed VWD, but in the group with PBS<2, VWD was diagnosed for only 4 children insert ignore into journalissuearticles values(0.02%); insert ignore into journalissuearticles values(4/134);. The sensitivity, specificity, positive predictive value insert ignore into journalissuearticles values(PPV);, and negative predictive value insert ignore into journalissuearticles values(NPV); of PBS for diagnosis of VWD was 79.0%, 87.2%, 44%, and 97% respectively. Conclusion: PBS could be integrated into the evaluation of children suspected of having a bleeding disorder such as VWD in pediatrician’s offices. Our cut off value 2 appears to be significant in exclusion of VWD, since its high negative predictive value.
