About

The investigators try to improve the screening of bleeding disorders in children by identifying symptoms, laboratory abnormalities and clinical scores discriminating patients congenital bleeding disorders in order to create a simple screening algorithm applicable in pediatrics, aiming for use in pre-anesthetic consultation and in consultation by pediatricians and general practitioners.

Full description

Objective : To determine simple clinical and biological factors that can improve the screening of hemostatic diseases at risk of hemorrhage in children.

Method:

• Retrospective inclusion of all patients <18 years referred to the CRTH in pediatric consultation for the reason of exploration of a hemorrhagic syndrome or exploration of an anomaly in the hemostasis assessment.
• Data collected (by collection in the medical file):

Patient data: Age, sex, personal and family history of hemorrhagic disease

Clinical data: hemorrhagic symptomatology (epistaxis, gingivorrhagia, etc.) Biological data: PT, TCK, factor assay, platelet function Medical data: complete diagnosis if diagnosis of hemorrhagic disease

• Scores: HEMOSTOP, PBQ, ISTH, TOSETTO score
• Analyzes: calculation of the Odd Ratio, AUC, Se, Sp, VPP, VPN for different clinical / biological factors and each score.

Enrollment: 96 patients

Sex: All

Ages: Under 18 years old

Volunteers: No Healthy Volunteers

Inclusion criteria

• referred by their general practitioner or another caring physician for evaluation of bleeding symptoms
• abnormal laboratory test results or family study
• the patient being the first-degree relative of a patient with a known bleeding disorder.
