Question: Menorrhagia
(Click the link to comment and to vote – voting not working through email, sorry!)
You are seeing a 13 year old girl for menorrhagia. This is her second menses ever, and she has been having to change her pad every 2 hours for 7 days. Her physical exam is unremarkable except for some mild tachycardia and ongoing vaginal bleeding. She has not had any surgeries, but she does recall a nosebleed episode that lasted 15 minutes, and she does endorse easy bruising. She is not taking any medications and has no significant past medical history. There is no known family history of a bleeding disorder, and she has one older brother who is healthy.Â

D) Von Willebrand Factor antigen
The most common inherited bleeding disorder is Von Willebrand’s disease. VWD presents with mucosal bleeding (e.g. with dental work, brushing teeth), prolonged epistaxis episodes, easy bruising, menorrhagia, and excessive bleeding with procedures or trauma. PT and aPTT are often normal in VWD. Thrombocytopenia often presents with petechiae as well as gum bleeding, menorrhagia, and/or blood in the stool or urine.
