Petechiae
Petechiae
Sorry, I didn't mean to frighten you as this is probably nothing to worry about, but I would get it doublechecked just to be safe. The concern, as I understand it, would be with the platelet count.
Katie has had two incidences of petechiae. The first time I thought it was a heat rash because it was just on her trunk - front and back, where her clothes rubbed and it was summer. Her ped, though, immediately diagnosed it as petechiae. Katie was on just aspirin therapy at the time - not coumadin, but her ped ordered a blood test anyway to check her platelet count. Her platelet count was a little below the norm, but nothing to be concerned about, and the petechiae went away after a few days. The second time I knew what it was and took her in. The ped ordered a blood test again just to be safe. Again, Katie's platelet count was a bit low, but nothing to be overly concerned about. Just as before, we did nothing different, and it went away on its own as before.
So, it wouldn't hurt to run this back by your dad's GP, especially if he is not well-versed in coumadin. I have to confess that we are new to coumadin, too, but I assume that the concern would still be with the platelet count.........dunno if that would mean that the INR is too high, too........maybe someone else on here could shed some light on that.
Here is one site's definition of petechiae (sorry I can't remember which one I got it off of, but if you google it, I'm sure you can find some stuff):
Definition of Petechiae
Petechiae: Pinpoint flat round red spots under the skin surface caused by intradermal hemorrhage (bleeding into the skin). Petechiae are red because they contain red blood that has leaked from the capillaries into the skin. Petechiae are quite tiny (less than 3 millimeters in diameter) and do not blanch when pressed upon.
There are many conditions in which petechiae may be seen. These conditions range from very minor to very major. The common causes of petechiae include local injury and trauma, allergic reactions, autoimmune diseases, viral infections that impair blood coagulation (clotting), thrombocythemia (an abnormally high platelet level), certain medical treatments such as radiation and chemotherapy, idiopathic thrombocytopenic purpura (ITP), leukemia and other bone marrow malignancies that may lower the number of platelets, and sepsis (bloodstream infection). Petechiae are commonly seen right after birth in the newborn and after violent vomiting or coughing. Drugs such as the anticoagulants warfarin (Coumadin) or heparin, aspirin, and cortisone can also cause petechiae.

Again, please remember that Katie had it twice and was fine both times. I just thought I should alert you that this is a possibility and might be worth keeping an eye on. I truly hope this helps and didn't mean to alarm you. Hugs. J.
