Hemophilia

Why?

● A newborn with bleeding from the umbilical stump should be evaluated for coagulation protein defects, including factor XIII deficiency [3]. Intracranial hemorrhage in an infant without other risk factors should also prompt consideration of this diagnosis. ()

A male infant who is starting to walk and presents with a painful swollen joint after a fall is presumed to have hemophilia until proven otherwise. Similarly, an unusually prominent forehead hematoma (“goose-egg”) in a male infant or young boy is a common presentation of hemophilia [4], as is excess bleeding after circumcision. (

“Clinical manifestations and An otherwise healthy child who presents with petechiae and/or mucocutaneous purpura in the wake of a viral infection most likely has acute postinfectious immune thrombocytopenia [5-8]. (.)

An adolescent girl who presents with excessive menstrual bleeding, recurrent nosebleeds, and pallor may have von Willebrand disease (VWD), the most common inherited bleeding disorder [9].

What is the importance ogFamily history ?

The family history is helpful in supporting a possible diagnosis of an inherited disorder of coagulation. The presence of bleeding manifestations only in male siblings and maternal uncles is suggestive of X-linked recessive inheritance, such as that seen in hemophilia A or B. However, a negative family history does not exclude an inherited coagulation disorder, as up to one-third of patients with hemophilia have a negative family history
